Miguel Stilwell d’Andrade CEO of EDP and EDP Renewables Message from the CEO 009 Integrated Annual Report 2022 Message from the CEO Our Company Dear Shareholders and Stakeholders, Rarely has our sector been in the spotlight as much as in the last year. The conflict in Ukraine has shown that our over-reliance on fossil fuels as a society is not only harm- ing the climate, but also compromising energy security and affordability. Investing in clean energy is critical to achieving environmen- tal goals such as Net Zero by 2050, but also to the long-term sustainability of the energy system. Governments, business and civil society must come together to ensure that there is more investment in renewables, relying on the power of the sun, the wind and water. In 2022 important steps were taken to achieve this goal. The European Commission increased the headline 2030 target for renewables installed capacity from 40% to 45% and approved important measures towards faster and more comprehensive permiing procedures, reducing European energy dependence and promoting energy efficiency. With this framework in place, it is now crucial that Member States urgently and adequately implement it in their jurisdictions. In the United States, the Inflation Reduction Act (IRA) represents a huge political accomplishment. By providing a simple, stable and long-term investment framework, it will further accelerate the development of clean energy and support our investment in the region. 

010 Integrated Annual Report 2022 Message from the CEO Our Company At EDP we are leading the needed energy transition across the world with a very clear mission: drive a beer tomorrow and create positivity to our stakeholders every step in the way. Our main achievements in 2022 Renewables generation In 2022 EDP grew significantly in renewables, adding 2.1 GW of renewables installed capacity and a pipeline of a further 4.0 GW under construction, more than twice the level we had in December 2021. We have now delivered more than 50% of our 20 GW capacity additions target for the 2021-25 business plan period. Besides concluding the establishment of our renewables growth platform for APAC based out of Singapore, we have acquired a solar developer company based in Germany that allowed us to expand our footprint in Europe to 12 countries, which together cover more than 90% of the expected solar capacity additions in the European Union until 2030. In Iberia, we commissioned our first hybrid solar and w ind energy park in the region and secured a grid connection that will allow EDP to build a 70 MW floating solar project in Alqueva hydro power plant – a project that falls within our more than 500 MW of solar and wind projects under development to hybridize our hydro assets – an innovative and efficient way of combining several renewable energy sources using the same grid connection point (a scarce resource in many markets. In the United States, we completed the construction of the largest solar park in Indiana and our first repowering project in Oklahoma, and we started construction on 13 new projects to reach a record of more than 2 GW of new capac- ity under construction in the country. In offshore, we are proud to be in the top 5 players world-wide, through the joint venture Ocean Winds 50% held by EDP Renewables, reaching by year-end a portfolio of 16.6 GW through 15 projects across 7 countries worldwide. We have evolved our presence in storage, starting construction on our first sizeable storage project in the United States. Regarding Hydrogen, we have produced our first hydrogen molecule in a pilot project in Brazil and our three green hydrogen initiatives in thermoelectric plants Aboño, Los Barrios and Soto Ribera in Spain have been selected as key projects to be supported by the European Commission and the Spanish Recovery and Resilience program. Networks In 2022 we invested more than 800 million euros in the development and optimization of our distribution networks and in the growth of transmission in Brazil, commissioning several new lots and finalizing the acquisition of EDP Goiás. We have distributed 85 TWh of energy (+0.5% vs 2021) and delivered an excellent performance in quality of service of our grids, reaching record levels at our Spanish platform and our Brazilian distribution company in Espírito Santo. By the end of 2022 we have installed 6.4 million smart meters (+740,000 vs 2021), allowing us to have 80% of energy metered (+3.3 pp vs 2021). Client Solutions Despite the extraordinary context in the energy sector that brought added complexity to our energy supply activity, we managed to maintain the price stability commitment assumed with our clients in Portugal and sustain a competi- tive price during the year. We have scaled our distributed solar generation business, a high growth and aractive energy transition technology, with total gross additions of 1.1 GWac over the past three years, across North America, Europe, Brazil, APAC, including as a result of multi-geography partnerships that secured large distributed solar energy installations across the world. We have also taken important steps in the democratization of access to decentralized solar generation through our energy communities which have reached more than 30 MWp of contracted capacity this year, enabling more than 35,000 neighbours to benefit from solar energy in self-con- sumption in Portugal. Regarding electric mobility, we have delivered our ambition to reach 3,000 contracted public charging points in the Iberian Peninsula. One of our flagship projects was the entry into operation of 50 fast and ultra-fast charging points across 17 locations in Portugal's main motorways, giving faster and modernized solutions to drivers in the country. Business enablement Despite the challenging context, in 2022 our workforce grew by 7.4% and EDP employs now more than 13,000 people with 64 nationalities spread all over the world. We continue to evolve as a global organization, supported by a common purpose: our energy and heart drive a beer tomorrow. We have launched a renewed brand identity that represents a more global and inclusive company focused on the future, 

sustainability, innovation, social responsibility, and on the ambition to lead the energy transition. We have continued to invest throughout our 7 innovation domains – renewables, smart networks, distributed solar, hydrogen, mobility, flexibility, storage – to accelerate the delivery of new solutions through 3 key channels – internal incubation, corporate venture capital and partnerships. Digital and Technology are an important accelerator and enabler of the energy transition. This year we implemented a new strategy focused on 7 critical action drivers – global, digital, cloud, data, cyber, excellence, people – and managed to migrate about 70% of eligible applications to the cloud. Our commitment to ESG excellence We have taken important steps to further strengthen our Environmental, Social and Governance (“ESG”) credentials across our company. Environment Within the just transition action plan, we made progress in the transformation of our coal sites in Spain and Brazil into Green Hubs alongside 4 business streams: green hydrogen, renewables, storage and flexibility. We kept our activities rooted in our commitment to the 10 principles of the United Nations Global Compact, notably to build a more sustainable world, aligned with the values of respect for environmental protection. Moreover, EDP became a signatory of the United Nations Sustainable Ocean Principles, recognizing the urgency and global importance of taking measures to promote the sustainability of the oceans for current and future generations. Social To address the inequalities of today and anticipate those of tomorrow, we created a central department fully dedicated to social responsibility, which aims to invest more than 300 million euros in social impact projects by 2030, promoting a fair energy transition and access to energy, while fighting energy poverty. We launched the fourth edition of the A2E (Access to Energy) Fund, supporting nine projects which provide renewable energy to remote and vulnerable communities in Mozambique, Nigeria, Angola and Malawi, with direct impact on priority areas such as health, agriculture, educa- tion and access to drinking water. Governance We have continued the transition to a business platform management model, streamlining our organizational structure and revamping the internal KPIs to ensure the proper alignment and incentives within the organization. Further-more, we have improved our decision-making process to promote efficiency, agility and simplicity on an increasingly global company. As we ensure that we follow corporate governance best practices and deliver the best interests of our stakeholders, we have obtained the highest score at the FTSE Russel’s ESG ratings for good governance practices and for quality of corporate governance. We progressed with our Health & Safety program (PlayitSafe) that aims to reach zero working accidents. This year the focus was training and education for all EDP leaders, from the Executive Board of Directors to managers across all business units, on the absolute commitment of the company to safety. There is still work to be done on this top priority area for EDP but I was proud to see that the organization recognizes its importance, with Safety being the dimension with the highest scoring category in our internal climate study of 2022. ESG recognition EDP's sustainability practices have once again been recog- nized in the S&P Dow Jones Sustainability Index, with EDP keeping its place as number one integrated electric utility, scoring 90 points, well above the sector average of 50 points. CDP Water and Climate Change recognized EDP as one of the world's leading companies in the fight against climate change for the sixth year. Furthermore, we saw our net-zero science-based target by 2040 approved by SBTi. The company was also included for the third consecutive year in the Bloomberg Gender-Equality Index, improving its overall score compared to last year, which reflects our commitment to creating a more diverse and inclusive work- place. In this context, we are proud to have launched our DEIB (Diversity, Equity, Inclusion, and Belonging) Global Policy, as well as an updated Gender Equality Plan (2022/2023) and an Equal Pay Project within our global compensation frame- work. Moreover, EDP was once again recognized by the Top Employer Institute as an employer of first choice. Finally, EDP is proud to have joined the Executive Commit- tee of the World Business Council for Sustainable Develop- ment (WBCSD), the largest international business organiza- tion promoting sustainable development. Our financial performance Despite 2022 being severely impacted by drought in Iberia and the huge price volatility resulting from the Ukraine conflict, we managed to deliver good results, with a recur- rent EBITDA of 4,522 million euros, representing a 21% increase year-on-year, benefiting from a strong perfor- mance of renewables, networks and thermal in Iberia. 011 Integrated Annual Report 2022 Message from the CEO Our Company 

Recurrent net profit of 871 million euros improved 6% compared to the previous year, driven by EBITDA growth, though penalized by higher financial costs. We have further strengthened our financial base with 2 billion euros of proceeds mainly related with 7 asset rotation trans- actions closed during the year, allowing us to crystallize value upfront and redeploy capital into new growth opportunities. Despite a challenging and volatile debt capital markets environment, we re-opened the senior Eurobonds’ market in March 2022 with a 1.25 billion euros issuance and in October 2022 we issued a couple of additional bonds, accessing both the Euro and US dollars markets for 500 million each. We signed our first sustainability-linked loan, amounting to 3.65 billion euros, linked to two ESG KPIs - reduction of scope 1 and 2 greenhouse gas emissions and increase in the percentage of installed capacity from renewable sources within EDP group. By year-end, green bonds already represented 44% of our financial debt. EDP maintained its “BBB” long-term corporate credit ratings by Standard & Poor's Global Ratings and Fitch Ratings, with Stable Outlooks, and also maintained its Baa3 rating with Positive Outlook from Moody’s. Looking ahead to 2023 I am immensely grateful to all those who have contributed to EDP's success over the last year. A special word of thanks goes to my dear colleagues of EDP’s Executive Board of Directors for leading by example and to the Chairman and all members of the General and Supervisory Board for their collaboration and advice throughout a very demanding year for EDP. I also thank our stakeholders, notably our shareholders, customers, suppliers, regulators, partners and local communities, for their trust and support along the way. Finally, I want to show my deepest gratitude to our 13,000 employees across the world who are the driving force of our company and the main contributors to its success. EDP is about to start a new chapter, strengthening its commitment to lead the energy transition, through a prom- ising strategic update for the 2023-2026 period. I look forward to working with all of you to achieve this goal together. Miguel Stilwell d’Andrade 012 Integrated Annual Report 2022 Message from the CEO Our Company

Resources A global energy company, leading the energy transition to create superior value. In the transmission the energy generated is delivered to the transport network, which is made of very high voltage lines and which then channels the energy to the distribution network. In EDP this is a growing business segment in Brazil. Generation is the first activity in the value chain of the electricity sector. Power plants transform the various energy sources into electricity. These energy sources may be of renewable or non-renewable origin. In EDP, 75% of the energy produced comes from renewable sources.

The distribution network allows the flow of energy to the supply points. Electricity distribution networks are composed of high, medium and low voltage lines and cables. EDP has made major investments in the modernization of its network such as the increase in the number of smart meters installed. In the supply activity the distributed energy arrives at the supply point and is sold by the supplier. Throughout the electricity and gas value chain, supply is the closest activity to the customer and responsible for the relationship with final consumers. EDP has been focusing on developing new solutions for customers responding to new challenges of the energy transition.

Stakeholder management is an extremely demanding exercise for companies that involves sharing informa- tion and being transparent in their relationship with society and, in particular, with all who are affected by their activities. Engaging with stakeholders is a strategic priority for EDP to establish an open dialogue, following the ESG (Environment; Social; Governance) growing impor- tance in the business world. EDP strongly believes this activity is key to enabling the implementation of the business plan, improving busi- ness success, anticipating risks, and also to create value for the stakeholders involved. To pursue these objectives, it has been fundamental to rely on the joint effort of all the EDP business units across the world to know their main stakeholders, understand their priori- ties and needs, establish continuous communication, and deploy ambitious action plans to tackle the main risks and meet stakeholder's needs. Understand > INCLUDE > IDENTIFY > PRIORITISE > INTEGRATE > SHARE > COOPERATE > INFORM Colaborate • We have dynamically and systematically identified the Stakeholders who influence and are influenced by the Company. • We analyze and seek to understand stakeholders’ expectations and interests in the decisions that impact them directly. > TRANSPARENCY > INTEGRITY > RESPECT > ETHICS Trust • We believe promoting trust with our stakeholders is crucial to establish stable and long-term relations. • Our relationship with stakeholders is based on such values as transparency, integrity, and mutual respect. > INFORM > LISTEN > UNDERSTAND Communicate • We are commied to promoting a two-way dialogue with Stakeholders through information and advisory activities. • We listen, inform, and respond consistently, clearly, accurately and transparently to stakeholders in order to build close, strong and lasting relationships. • We aim to work with stakeholders to build strategic partner- ships that collate and share knowledge, skills and tools, thereby promoting the creation of shared value in a differentiated way.

Integrated Annual Report 2022 Strategic Approach Global energy trends 028 2.1. Global energy trends An extraordinary challenge Limiting the increase in global temperature to 1.5°C compared with the pre-industrial levels requires the global economy to fully decarbonize by 2050. To overcome this unprecedented challenge, there must be a coordinated commitment from all countries, involving policymakers, businesses, and consumers. Currently, more than 130 countries have announced or are considering net-zero targets, covering 83% of global emissions. This corresponds to more than 90% of the global GDP and 80% of the world population1. However, the announced pledges fall short of reaching the target by 2050, and there is still an ambition gap to be fulfilled (see figure below). GLOBAL CO2 EMISSIONS BY SCENARIO, 2010-2050 1 Data retrieved from Net Zero Tracker on January 6th, 2023 As an overarching target, providing access to electricity to the entire global population is critical to clean and energy-efficient demand. Many of the poorest households often use low- quality and polluting fuels, with impacts on their health and the environment, combined with inefficient equipment. The International Energy Agency (IEA) considers that under a carbon neutrality scenario, there will be no one without access to electricity by 2030, compared to 770 million people today. An energy transition driven by three key pillars A global energy crisis marked the year 2022, with high commodity prices impacting businesses and households. The exposed fragilities of a fossil fuel-dependent energy system reinforced the need for change and highlighted the importance of pursuing the main carbon neutrality drivers: renewables, electrification, and energy efficiency. The IEA estimates in its Net-Zero Emissions scenario of the World Energy Outlook 2022 that clean technologies must dominate the energy mix to enable the energy transition. While today fossil fuels account for 80% of the primary energy demand, there will have to be a complete change in the coming decades. Renewables should represent 70% of the mix by 2050, and the remaining fossil fuels must be combined with carbon capture and storage technology (see figure next page). Decarbonization is happening at a faster pace in the power sector, in which renewables are already a cost-competitive solution for most key markets around the world. More than two-thirds of the world population lives in countries where either onshore wind or solar PV are the cheapest technologies for new builds (BloombergNEF). Electric solutions are often more efficient than other alternatives, as is the case of electric vehicles or heat pumps. All in all, electrification supported by a renewable mix should be the most effective solution for cleaner and more efficient energy consumption. 

Integrated Annual Report 2022 Strategic Approach Global energy trends 029 GLOBAL PRIMARY ENERGY DEMAND FOR THE NET-ZERO SCENARIO Source: International Energy Agency, World Energy Outlook 2022 Energy efficiency plays a critical role, since more efficient appliances ensure a lower energy demand, reducing costs, and ultimately lowering energy bills for consumers. Some of the most effective energy efficiency measures include renovating buildings and investing in efficient appliances, reducing energy needs, and improving thermal comfort. Other clean technologies are necessary to reach net-zero Renewables, electrification, and energy efficiency will be the key pathways to pursue to reach carbon neutrality. However, global decarbonization efforts will have to be complemented by investment in alternative low-carbon technologies, especially for hard-to-abate uses. Hydrogen will play an important role in sectors such as heavy industry, long-distance, and heavy-duty vehicles, shipping, and aviation. With the expected decrease in the cost of electrolysers and in the cost of electricity generation, renewable electrolysis should become a more competitive solution to produce hydrogen. Hydrogen has been gaining global recognition, and today more than 50 countries already have either a Hydrogen National Strategy or are preparing one (BloombergNEF). The future power system will also require a strong increase in the availability of flexible technologies as a response to the intermittent nature of renewables. From mature technologies to the ones still growing, all will have an important part to play, including pumped hydro, battery storage, interconnections, and demand-side response. Innovation and digitalization as key enablers To keep up with the decarbonization goals, innovation will be essential, as we need to adopt existing technologies at a faster rate while developing new ones. R&D will be critical to further develop the technologies that are still in the prototype or demonstration phase and without which carbon neutrality cannot be reached. Digitalization also offers several opportunities for utilities throughout the entire value chain, fostering energy transition. For the generation side, digitalization solutions will comprise embedding data into everyday activities to maximize outputs and operations efficiency (e.g., predictive maintenance, automated work). For networks, a more digital business will facilitate managing a system with much higher levels of renewables and distributed energy resources, while also making operations more efficient (e.g., smart meters, smart grids, predictive maintenance).

Integrated Annual Report 2022 Strategic Approach Materiality 031 2.2. Materiality EDP's Materiality analysis process has been developed since 2016, through a transversal methodology, common to the whole group, systematised and detailed in a specific report available at www.edp.com. The EDP group carries out its Materiality process every two years, accompanying the revision of its Business Plans. This process makes it possible to identify the relevance of non-financial issues for stakeholders, cross-referencing it with their relevance to the business priorities and strategy. This analysis supports the decision-making process and the development of strategies in the organization, particularly the clarification of its performance in terms of sustainability. The main stages of the materiality process are described in the infographic on the right. EDP's methodological approach in the definition of materiality considers the concept of double materiality, as defined by GRI Standards. This alignment reflects the importance given by the group to the relevance of the issues for society, in which it takes into account their impact on its stakeholders. However, as the concept of double materiality becomes operational in the international regulatory context, namely with the creation of the International Sustainability Standards Board and as defined by the European Financial Reporting Advisory group (EFRAG), EDP is dealing with possible adjustments to its methodology for identifying material themes in subsequent reports, in order to meet the expectations of its stakeholders and fulfil its commitment to society and the environment. In 2022, material themes remain stable compared to 2021, and 18 material themes have been identified for the EDP group, whose relevance for society and for business is positioned in accordance with the matrix presented on the following page, highlighting: 7\. Customer Satisfaction and Service \- Sustainable Consumption stands out for its increased relevance for both society and business. Thus, this is a subject to which EDP intends to give particular focus in its activity plan. Additionally, the growing weight of the issue of Energy Prices at a European level was also identified as one of the most relevant issues for society in 2022\. 

Integrated Annual Report 2022 Strategic Approach Materiality 032 6\. Safety - Mental Health has distinguished itself by the increasing growth of its relevance to society, distinguishing it from other Safety themes for 2022. 17\. Supplier Management \- The growing relevance of the topic for business and society is due to the increased importance given to environmental criteria in the supply chain, namely the reduction of CO2 emissions in the context of decarbonisation, in light of global goals. The Materiality process also makes it possible to identify the degree of priority given by each stakeholder group to sustainability issues. This analysis shows a natural dispersion of the relevance attributed by various stakeholders to the analysed themes, inherently related to their nature and relationship with the company. The figure in the next page details the identified themes, aggregated by the degree of relevance attributed to each of the stakeholder groups.

Integrated Annual Report 2022 Strategic Approach Risk management 034 2.3. Risk management 2.3.1. Risk governance model The EDP group follows a risk governance model, generally recognised in specialist literature 1, based on the concept of three lines of defence internal to the organisation - which may be complemented, in specific circumstances, by a fourth external line of defence, in the form of external auditing and regulation/supervision. For every line of defence there are clearly defined responsible bodies and forums for debate and decision, formally established to materialize each line of defence at corporate and Business Units levels, avoiding duplication of efforts and/ or the existence of gaps, and promoting the cooperation and collaboration between different areas. RISK GOVERNANCE MODEL OF THREE LINES OF DEFENCE 1 Instituto de Auditores Internos em IIA, Position Paper, The three lines of defense in effective risk management and control, Janeiro 2013 Risk management is represented by the Risk – Corporate Global Unit at corporate level, as well as by the local risk units across the Business Units (lead by their respective risk-officer) that functionally report to the Risk – Corporate Global Unit, guaranteeing a fluid articulation and communication concerning key risk sources and mitigation actions. In addition, Risk Committees are held at corporate level and locally, at Business Units, gathering top management and relevant specialists for the analysis, debate and advice on key risk exposures for the group, respective limits and other mitigation actions. A more detailed description about the intervening bodies in the risk governance model at EDP group, as well as attributed responsibilities, is available in the Corporate Governance Report. CORPORATE FUNCTIONS 

Integrated Annual Report 2022 Strategic Approach Risk management 035 2.3.2. Key risks EDP group seeks to have a comprehensive view over the key risks it is exposed to, at strategic, business, financial and operational level, establishing processes to assure follow-ups and proactive management. The year 2022 was marked by the geopolitical crisis caused by the conflict in Ukraine, resulting in an energy crisis (in part of the year aggravated by a period of drought in Iberia). The financial markets also noted some concern about the sharp rise in inflation and increase in interest rates. Risk management reaffirmed its importance, playing an essential role in this disruptive environment. A more detailed description of the various risks is available in the Corporate Governance Report.

Emerging risks Besides the close monitoring of the main risks inherent to the group's activity, the main trends (global and sectorial) that may translate into threats and opportunities for the group are also comprehensively mapped, and adequate mitigation strategies are proactively developed. In 2022, the emerging risks assessment was updated, with the evaluation by EDP group's top management, executive and non-executive. The most relevant emerging risks, even due to their impact over recent years, are (1) the regulatory risk and unadjusted energy market design, (2) the instability of global supply chains, (3) the increased inflationary pressure and rising interest rates, (4) the growing threat of cyber-risks and (5) the increase in climate risks (physical and transition risks), as well as the potential misalignment of international commitments for climate transition, and (6) the lack of talent supply in the labour market. Description Impact Mitigation Measures Regulatory risk and energy market design mismatch Structural change from a centralized towards a decentralized energy production model, and greater need for flexibility, along with efforts to decarbonize the economy. In this sense, a progressive revision of the regulatory framework is necessary. • Potential abrupt change in remuneration mechanisms, as well as their possible retroactive consequences, impacting profitability of current businesses and discouraging new investments. • Unclear market design could lead to market or investment incentive distortions (e.g., to address supply chain constraints / price spikes). • Close monitoring of regulatory developments and active participation in national and international discussions. • Diversification by business line and by geography. • Creation of contractual resilience in order to share the risk of possible structural changes in market design. Instability of global supply chains Global supply chains exposed to extreme events (e.g., environmental, social, geopolitical, macroeconomic) leading to supply disruptions or price pressure. Geographical concentrations of raw materials enhance this risk. Threats related to: • Fuel and raw materials/equipment supply chain constraints, critical to new investments; • Delays in maintenance, construction, among others; • Possible impact on operations, costs of delays (COD) and CAPEX deviations in new investments. • Analysis and assessment of supplier exposure to potential supply chain disruptions and monitoring of critical suppliers (taking into consideration financial criteria and ESG criteria), as well as supplier diversification reducing dependencies (mainly for critical supplies). • When applicable, evaluation of the trade-off of extending ongoing contracts vs. new bids/anticipating purchases to cover shortages and price increases. Increased inflationary pressure and rising interest rates Rising inflation and upward pressure on interest rates (exacerbated by the conflict in Ukraine) pressing liquidity of population and businesses, leading to extraordinary governmental measures (e.g., extraordinary taxes and fees). • Increase in the company's financial costs. • Generalized increase in the cost of raw materials and equipment, impacting the profitability of assets in operation and under construction. • Current asset sale strategy impacted by changes in investors’ appetite. • Integrated inflation control - aligning revenues with inflation-related costs (directly or through proxies). • Maintenance of a mostly fixed debt strategy and increased debt duration. • Prudent liquidity management. Cyber-risks Exposure to cyber risks of different natures, arising from of increasing technological sophistication and integration. Financial, operational and reputational loss, arising from (among others): • Operating losses/interruption (dispatch/plants, billing, customer service); • Damage/destruction of assets (networks, central offices, other systems); • Data breach/destruction (personal and others). • Continuous improvement of the security of internal systems. • Dedicated Security Operations Center (SOC) for continuous security monitoring of the group's OT/IT infrastructure. • Dedicated Cyber-range for simulation and testing to cyber attacks • Online training and awareness actions on information security principles. • Cyber risk insurance. Increased climate risks and potential misalignment of international commitments for climate transition Physical risks associated with climate change (e.g., chronic risks such as increased temperature or reduced precipitation, and acute risks such as extreme temperature and precipitation events) impacting portfolio profitability and increasing costs. In a transition phase other regulatory, technological obsolescence, and market risks arise. • Structural loss of portfolio profitability: o Damage to physical assets and loss of revenue caused by more frequent extreme weather events. o Increases in overall costs (including insurance). • Limitation of the economic potential of investments in new technological solutions (e.g., green hydrogen). • Structured assessment of climate risks (TCFD), updating scenarios, evolution of climate variables and key risks and opportunities for each business. • Development of climate adaptation plans by Business Unit in line with the main risks identified. • Integration of climate risk assessment into investment analysis. • Close monitoring of national and international commitments in decarbonization and adjustment of EDP's strategy accordingly. 

Integrated Annual Report 2022 Strategic Approach Risk management 040 Description Impact Mitigation Measures • Asymmetry between energy sectors across countries (e.g., European integration) and across economic sectors (e.g., restrictions on energy sector versus transport). • Geographic, technological and business line diversification. Lack of supply of talent in the labour market Increased competition for labour resources (skilled and unskilled), structural changes in work culture (driven by remote), and digital transformation. • Lack of talent supply to meet the company's human resources needs, impacting team sizing and productivity (including digital). • Rise of personnel costs and other benefits, as a way to attract talent. • Increased difficulty in retaining talent in the company. • Increased presence in social networks, participating and developing hiring and networking initiatives, youth-oriented programs, more agile recruitment and inclusive methodologies. • Flexibilization of work in line with new reality of and work culture. • Global development of the company culture as a talent management strategy (development and internal requalification) and development of the internal market. More details on the TCFD climate dashboard framework is available on the Climate Transition Plan report. 

Integrated Annual Report 2022 Strategic Approach Risk management 041 2.3.4. Risk appetite The EDP group is exposed to a number of risks due to its dimension and diversity of businesses and geographies in which it operates, hence it recognizes risks as an integral and unavoidable component of its activity, both as threats as opportunities. Acknowledging this fact, the group establishes explicitly and implicitly its risk appetite for all internal and external stakeholders, both at corporate and Business Units level, as well as for the various categories of risks, through a set of mechanisms: • the periodical development and approval of the group’s Business Plan by the Executive Board of Directors, which is communicated to all stakeholders, and where key strategic orientations are set for the upcoming three to five years; • the rigorous evaluation of risk related to investment and divestment opportunities proposed by the Business Units and approved by the Executive Board of Directors, including the estimation of returns adjusted to risks vs. established hurdles. This evaluation is supported by the opinion of the Investments Committee, which includes specialists from relevant areas of expertise; • the development of a wide set of risk management policies, both at corporate and Business Unit level, which establish guidelines, methodologies of evaluation and exposure limits for key risks 2 ; • the periodical development of risk mapping exercises, based on objective, quantitative and comparable criteria, allowing an analysis of the exposure to key risks, as well as the adoption of preventive treatment actions for excessive exposure to risks (regarding the established tolerance of risk); • the establishment of a wide set of mechanisms for periodical reporting of key risks, at group and Business Unit level, thus allowing a regular monitoring of the evolution of actual and emerging risks, and comparison of the exposure to different risk profiles within the established limits; • the adoption of a risk governance model based on three independent lines of defense (business, risk/ compliance and internal audit), which guarantees the implementation of the established strategies and alignment with risk appetite; • the definition of an internal framework for risk appetite, approved by Executive Board of Directors. 2 Including, among others, the Enterprise Risk Management Policy, the Risk Appetite Framework Policy, the Limits Structure of the Energy Management Business Unit, the Financial Management Policy, the Counterparty Policy, the Insurable Risk Management Policy, the Occupational Health and Safety Policy, the Information Security Policy, and the Principles, Structure, and Procedures for Crisis Management and Business Continuity. • the periodic reporting to the EBD and GSB of risk indicators and limits aligned with the group's strategy and performance metrics. The framework of risk appetite in EDP group is structured around four pillars: • The governance model identifies the key actors in the process of risk appetite and their responsibilities; • The risk appetite statement formally defines a set of risk appetite statements complemented by risk indicators and thresholds. In terms of positioning, the group establishes maintaining a controlled risk profile as a fundamental pillar of its strategy; • The monitoring and follow-up, defining the key processes of monitoring, update and action plan; • And the technological platform, embodied in a risk appetite dashboard that allows the follow up of risk appetite in EDP group. The group is exposed to a number of risks inherent to its dimension and diversity of business and geographies where its present, recognizing the risk assumption as an integrant and inevitable component of its activity, as a threat and opportunity.

Integrated Annual Report 2022 Performance Markets and regulation 052 3.1. Markets and regulation 3.1.1. Fuels in the world and Europe The commodities’ market in 2022 was marked by high volatility, impacted by multiple factors from the demand and supply sides. Prices started trending upwards in 2021, as a faster than expected economic recovery led to a growth in fuel demand that was not fully met by supply, and this imbalance was severely aggravated by Russia’s invasion of Ukraine in February of 2022, with a stronger impact felt in Europe. Pressure on commodity prices coupled with disruptions in the global supply chains contributed to high inflation levels, which have begun to ease by November. The average price of Brent crude oil in 2022 was 104 dollars per barrel ($/bbl). With a reference of 70 $/bbl at the start of 2022, the price increased in the first trimester due to a lower than expected increase in production from OPEC+ (Organization of the Petroleum Exporting Countries and associates) and the impact of the Russian invasion of Ukraine, reaching a maximum of 135 $/bbl in June. However, in the third and fourth trimesters, China Covid restrictions and a slower global demand contributed to a price decrease, with the year ending with Brent at 83 $/bbl. Natural gas experienced the highest volatility of all key fuel commodities, especially in Europe. The European reference gas index (TTF) price at the beginning of the year was 86 €/MWh, and it reached 204 €/MWh in March, as Russian exports began to be curtailed. The rush to replace Russian gas and fill the European gas reservoirs drove the price even higher in competition with JKM for liquefied natural gas (LNG), and the TTF reached a record of 309 €/MWh in August. As European storage levels reached the European Union’s set targets, and milder than expected temperatures persisted late in the year, prices remained volatile with a low of 29 €/MWh in October but increasing to a maximum of 128 €/MWh by December. The average annual price was 123 €/MWh. API#2, a widely used European price reference for coal, started the year at 120 $/ton, but the onset of the war in Ukraine led to a significant jump in price, reaching a peak of 439 $/ton in March due to reduced coal exports from Russia. However, the final trimester of the year saw bearish pressure on the market, and the API#2 price fell to 234 $/ton by the end of the year. Despite this fluctuation, the average price of API#2 throughout the year was approximately 291 $/ton, significantly higher than the 122 $/ton for the year of 2021. The carbon price in Europe in 2022 saw a mix of ups and downs throughout the year, averaging 81 €/ton. Several events led to fluctuations in the price, with the lowest price of 57 €/ton registered in March. In August, the price briefly reached 99 €/ton due to the typical reduction in primary auctions, which resulted in a surge in demand in the secondary market. This price point represented the historical maximum and highlighted the influence of market dynamics on the price of CO2. ANNUAL COMMODITIES AND CARBON PRICES EVOLUTION Source: Reuters, ICE The wholesale power prices in several European markets had a strong increase throughout 2022, mostly reflecting the escalation in natural gas prices, but also, even if at a lower degree, the CO2 price. In Spain and Portugal, the Iberian exception mechanism led to a lower pool value than the rest of the European countries, with an average of 168 €/MWh. Most of the markets registered values significantly higher, with France reaching a historical high of 3000 €/MWh in April due to several outages in their nuclear fleet and ended the year with an average of 275 €/MWh. 71 120 46 11 53 104 291 123 21 81 Crude oil Brent ($/bbl) Carvão API#2 ($/ton) Natural gas TTF (€/MWht) Natural gas Henry Hub (€/MWht) CO₂ (€/ton) 2021 2022 

Integrated Annual Report 2022 Performance Markets and regulation 053 ANNUAL EUROPEAN MARKETS POOL PRICE EVOLUTION (€/MWh) Source: OMIE, Nordpool, GME, Reuters. 3.1.1.1. Macroeconomic context Inflation was a major talking point this year. The average inflation in the Euro Zone was 8.4%, a significant increase from the 2.6% registered last year. This very high value was mainly driven by the high energy prices. To tackle this, many countries applied extraordinary measures in order to contain the impact of the escalation of energy prices in the wholesale markets. For Portugal, the average yearly inflation was slightly below the Euro Zone with +7.8%, while Spain was in line with the European average, registering +8.3%. The real GDP in 2022 increased by 6.7% and by 5.5% year-on-year, in Portugal 1 and in Spain 2 respectively, pushed by private demand from families and by private investment. In Brazil, on the other hand, the inflation was 5.9% in November 2022, a reduction compared to 2021’s inflation value (10.06%) which was the highest level in 6 years. The accumulated GDP 3 in the four quarters ending in September 2022 increased by 3.0% compared to the immediately previous four. In this period, industry (+0.8%) and services (+4.4%) had a growth, while agriculture fell by 1.31%. However, comparing just the third quarter of 2022 with 2021, 1 “Instituto Nacional de Estatística” of Portugal 2 “Instituto Nacional de Estadística” of Spain 3 “Instituto Brasileiro de Geografia e Estatística” (IBGE). the GDP growth was 3.6%. Industry had an increase of 2.8%, whose 11.2% represents electricity and gas segments, and waste management activities with “cheaper tariffs” (green energy flags) contrasting with the hydro crisis in 2021. Services (+2.8%) and farming (+3.2%) also increased. 3.1.2. Energy and environmental policy in Europe To address the disruptions in the commodity markets and security of supply concerns, the European Commission presented the REPowerEU plan on May 18th. The plan aims to turn the European energy system into a more resilient one, by accelerating the energy transition and reducing the European Union’s dependence on Russian fossil fuels. To achieve that, the REPowerEU plan lies on four main pillars: accelerate the energy transition, diversify energy sources, save energy, and smart investments. The plan considers several short-term measures to address the gas supply concerns, and also medium-term actions, including the definition of more ambitious renewable and energy efficiency targets for 2030. Regarding the share of renewables in demand, the REPowerEU plan proposes setting a target of 45% share for 2030, five percentage points above the Fit-for-55 target. This higher ambition is expressed in the different sectors, with specific targets for each of them: 69% for the power sector, 46% for heating and cooling, and 32% for transport. In the power sector, the plan foresees reaching a total of 1,236 GW of renewable capacity by 2030, of which 592 GW of solar PV capacity and 510 GW of wind, a multiple of 2.5 versus today. Accelerating the capacity deployment will require speeding up permitting processes, and the plan proposes establishing a maximum period for renewables permitting of 1 to 2 years and creating “go-to” areas which are specific locations designated as suitable for the installation of renewable plants. An ambitious target of 20 Mton of green hydrogen by 2030 was also set in the plan, which foresees 10 Mton of internal EU production and 10 Mton of imports. 111 132 125 109 62 97 168 216 304 275 136 234 Iberia UK Italy France Nordpool Germany 2021 2022 

Integrated Annual Report 2022 Performance Markets and regulation 054 In terms of energy savings, the REPowerEU plan proposes an efficiency target of 13% versus 9% in the Fit-for-55. The REpowerEU plan requires an additional €210 billion in investment through 2027 on top of the Fit-for-55 package. This includes, among others, €113 billion for renewables and key hydrogen infrastructure and €56 billion for energy efficiency and heat pumps. Some of the measures proposed by the European Commission already received the agreement of both the European Parliament and the European Council, and counterproposals, as in the table below. REPOWEREU APPROVAL STATUS EUROPEAN COMMISSION PROPOSALS EUROPEAN PARLIAMENT EUROPEAN COUNCIL Renewable energy target of 45% by 2030 Proposal of 40% Permitting processes maximum period & ‘go-to’ areas implementation Energy efficiency target of 13% by 2030 Proposal of 14.5% During the year 2022, some progress was made in the approval of the Fit-for-55 package. Not only targets were revised to incorporate the REPowerEU plan, as stated previously but also some steps forward were taken, namely: • a provisional deal on the revision of the Emissions Trading System (ETS) was reached between the European Parliament and the Council, with an upward revision proposal of the emissions reductions target from 61% to 62%. This corresponds to a reduction from 2005 to 2030 in the emissions from the sectors covered by ETS • a provisional agreement on the Carbon Border Adjustment Mechanism was reached between the European Parliament and the Council, establishing a mechanism that taxes CO2 emissions from imported goods coming from outside the EU • an agreement on the CO2 emissions standards for cars and vans was reached between the European Parliament and the Council, establishing the target of a 100% reduction in CO2 emissions by 2035, which implies the end of internal combustion engine cars and vans sales by then 3.1.3. Iberian Peninsula 3.1.3.1. Evolution of the electricity sector In 2022, electricity consumption in Spain fell significantly, reaching a 20-year low due to the combination of high electricity prices and lower industry demand, the sector with the most sensitivity to price volatility. In Portugal, electricity demand was higher than in 2021 even surpassed 2019 levels. • Portugal: +1.8% annual demand increase (+2.4% adjusted for temperature and business days effects) Source: REN 28% 24% 1% 28% 4% 15% 19% 32% 29% 6% 14% 2022 44,1 TWh 2021 46,7 TWh 

Integrated Annual Report 2022 Performance Markets and regulation 055 • Spain: -2.9% annual demand reduction (-3.8% adjusted for temperature and business days effects), with a strong decrease in the last trimester of -7.5% Source: REE Regarding electricity generation, 2022 was a year with very low hydro inflows in the Iberia Peninsula as the hydro production index (IPH) stood at 0.6 in Portugal and 0.7 in Spain. The low hydro availability and higher exports to France, following the implementation of the Iberian gas cap mechanism, led to an increase in the gas and coal generation. Renewable generation supplied 57% of power energy in Portugal in 2022, with wind generation representing 29% of the total, while hydro’s share stood at 19%. In Spain, renewables supplied almost 44% of the electricity demand, with the increase in solar generation (+25% YoY) partially replacing the lower hydro output. In Portugal, despite the increase in demand (+1.8%), electricity generation was 5.7% lower, leading to a rise in imports. 3.1.3.2. Regulatory Framework Portugal On 14 January, Decree-Law 15/2022 was published, establishing a new organisation and management of the National Electricity System (SEN). To mitigate the high energy prices in Portugal, following the energy crisis exacerbated by the Russia-Ukraine conflict, the Portuguese Government has approved several measures, namely: • the extraordinary and temporary mechanism for adjusting the costs of electricity generation in the MIBEL (“Iberian Mechanism”) • the suspension of the competitive equilibrium mechanism (“Clawback”) during 2022 • the suspension of ISP and CO2 added tax in the last quarter of 2022, as well as their prorogation in 2023 • a reduction of the VAT rate in electricity supply according to the consumption tiers (to the reduced VAT rate) • the Energy Saving Plan 2022-2023 (“Plano de Poupança de Energia 2022-2023”) With impact on the generation activity, in response to the severe drought experienced in Portugal’s mainland for most of 2022, a Hydro Strategic Reserve (“Reserva Estratégica Hídrica”) was set and a temporary suspension of the use of water resources of 15 hydropower plants (13 belonging to EDP) from 1 st of October 2022, until the minimum levels of storage of their useful capacity are reached, fixed administratively. Concerning the retail activity, the status of Electro intensive Consumer (“Estatuto do Cliente Eletrointensivo”) was established and measures were approved to simplify and provide flexibility to several tax and declarative obligations arising from the sale to the grid of the surplus of electricity produced for self-consumption. An exceptional and temporary measure was also approved allowing the return to the regulated tariffs to final consumers with gas consumption equal to or below 10,000 m 3 , and additional obligations were imposed on operators considered dominant (market share exceeding 20% in volume or number of customers), in particular, to promote continuity of supply. 13% 22% 15% 2% 24% 10% 14% 8% 21% 23% 3% 23% 12% 10% 2021 246,9 TWh 2022 262,1 TWh 

Integrated Annual Report 2022 Performance Markets and regulation 056 Within the scope of renewables, the targets for energy consumption from renewable sources were established, partially transposing Directive (EU) 2018/2001. Several extraordinary measures for the simplification of licensing procedures for energy production from renewable energy sources were also approved (in line with the REPowerEU Plan proposed by the European Commission). In the electricity tariffs, the regulator (ERSE) proceeded with two updates to the energy tariff during 2022, reflecting a 5 €/MWh increase from April 1 st and October 1 st onwards, and an extraordinary tariffs settlement in the 2 nd semester of 2022, establishing an average reduction of the network tariffs (TAR) of 102% and an increase of the energy tariff of 23%. For 2023, a transitory tariff to the end user in the normal voltage network (BTN) increase of 3.3% was approved and an average decrease of TAR of 506%. Regarding the electricity sector tariff debt, the tariffs foresee an ex-ante debt of 879 million euros by the end of 2023, a reduction of 830 million in comparison with the end of 2022. A tariff debt reduction has been observed since 2015, the year in which it reached its peak, according to the sector’s sustainability target. Related to the gas tariffs, ERSE proceeded with two updates to the energy tariff during the gas year 2021-2022, a 2 €/MWh increase from April 1 st and July 1 st . The gas tariffs for the year 2022-2023 were also approved, in force from October 1 st 2022, until September 30 th , 2023, with an increase of the transitory tariff to the end user in low pressure of 8.2%, which suffered a first quarterly update with an increase of 2€ /MWh in force from January 1 st , 2023, onwards. Spain Given the current crisis resulting from the conflict between Russia and Ukraine, the main measures taken have been aimed at reducing the impact of the rise in energy prices, as well as encouraging savings and promoting renewable energies. As main consumer protection measures: • fiscal measures were extended until the end of 2023: VAT reduced to 5% for electricity and gas, special tax of 0.5% on electricity, and temporary suspension of the Tax on the Value of Electricity Production (IVPEE) • a new mechanism for financing the social bonus was regulated so that all parties in the electricity sector will have to pay it. The range of vulnerable consumers with the right to the social bonus was extended • a new Tariff of Last Resort (TUR) was established for community heating systems in force until the end of 2023, which will be financed by the General State Budget 2023 (3,000 million euros). As measures to protect industry: • the 80% reduction in tolls for the electro-intensive industry was maintained until June 30 th , 2023, and the flexibility of natural gas supply contracts was regulated • the gas reduction mechanism was extended until the end of 2023 and its scope of application was extended to energy contracted at a fixed price if the price is higher than 67 €/MWh, excluding coal and RECORE • in May, a temporary adjustment mechanism was established for the production cost of marginal fossil fuel technologies, which aims to obtain a reduction equivalent to this adjustment in the bids made by these technologies on the market. The amounts corresponding to this adjustment are financed by those consumers who benefit from the aforementioned reduction. As measures to promote renewables and reduce consumption: • regulation aimed at administrative simplification in processing, commissioning, and injection is formulated. In self-consumption, the distance between production and consumption is extended to 2 km, and the minimum time of permanence in a modality is reduced to 4 months. In addition, for low voltage self-consumption installations of up to 100 kW with surpluses, a maximum period of 2 months was set for the activation of the contract. If this period is exceeded, the consumer will receive a "discount for the delay in the activation of self-consumption", which must be expressly stated on the bill • distributors were temporarily obliged to include in their annual investment plans actions to increase capacity for access to new renewable generation and self-consumption • Measures associated with the use of basic underground storage facilities were established for the 2022 gas year • the Council of Ministers approved the Plan + SE, which aims to reduce gas consumption by between 5.1% and 13.5%, improve energy autonomy, and increase the competitiveness of the economy and energy exports, in solidarity with the rest of the EU • in September, an active demand response service was created, configured as a specific balancing product with annual contracting by auction 

Integrated Annual Report 2022 Performance Markets and regulation 057 • regarding the rest of the regulatory measures, electricity storage is assimilated to generation for the purposes of its processing, and RD 413/2014 is amended to allow the installation of storage associated with RECORE • the processing of modifications to installations in the gas system network to adapt them to the injection of renewable gases was eased and Law 34/1998 on Hydrocarbons and RD 1434/2002 were amended to facilitate the connection of direct lines for renewable gases • the general framework of the regulatory sandbox for the promotion of research and innovation in the electricity sector was established In addition, a temporary levy on energy and credit institutions was approved in December, to be applied in 2023 and 2024 based on the results of 2022 and 2023. It is a non-deductible levy, and it will be calculated as 1.2% of the net turnover of the activity carried out in Spain, excluding regulated activities. Neither the total amount payable nor the initial payment may be passed on. Regarding the distribution activity, on 31 May, Order TED/490/2022 was published, implementing the Supreme Court ruling in relation to the declaration that Order IET/980/2016, of 10 June, which establishes the remuneration of electricity distribution companies for 2016, is detrimental to the public interest. In addition, Order TED/749/2022, of 27 July, approves the incentive or penalty for the reduction of losses in the electricity distribution network for 2016, modifies the base remuneration for 2016 for several distribution companies, and approves the remuneration of electricity distribution companies for 2017, 2018 and 2019. 4 Experts consulted include GWEC, IHS Markit, Bloomberg New Energy Finance, Wood Mackenzie, IEA, Wind Europe, and the American Clean Power Association, among others 3.1.4. EDPR Markets 3.1.4.1. The evolution of renewables around the world Wind In 2022, wind capacity additions were around 95-98 GW, according to energy analysts4. Of this, around 90% was onshore wind (84-88 GW) and the remaining capacity was offshore (9-13 GW). Although wind global net capacity added to the power system in 2022 remained fairly the same as in 2021, the additions on onshore technology were significantly higher than offshore. Overall, China remains the largest wind market, although additions have dropped from last year’s record-breaking figures. According to the National Energy Administration (NEA), China added 37.6 GW of wind power, down 21% in annual terms, due to the end of subsidies to offshore projects and to the imposed restrictions associated with the Covid-19 pandemic. In the USA, sources point to 10-11 GW of onshore wind capacity installed in 2022. This is a slowdown compared to previous years, which is mainly explained by the phase-down of the Production Tax Credit (PTC) prior to the approval of the Inflation Reduction Act (IRA). Onshore wind installations in the European Union represented around 90% of the total of 15 GW, according to Wind Europe, with Germany, Sweden, Finland, Spain, and France leading the ranking. Regarding offshore, France commissioned its first wind farm with a capacity of 500MW, while the UK added 3 GW to the energy system, one of the countries ranking highest in terms of offshore wind additions. Meanwhile, in Latin America, Brazil was likely the largest market in 2022, with wind experts pointing to around 3 GW of new onshore wind additions. All analysts highlighted the challenges faced by the wind industry. The difficulties felt on the supply chains across the globe affected the wind deployment rate, and the higher cost of materials and turbine components caused disruptions in the business of turbine manufacturers. Besides the 2022-specific challenges, the constraints felt before 2022 are 

Integrated Annual Report 2022 Performance Markets and regulation 058 still being tackled, namely the slow and bureaucratic permitting processes \- acknowledged by many analysts to be one of the main obstacles to a faster deployment of onshore wind. Solar PV Solar PV reported additions were very distinct from source to source with a range of 206 to 268 GW of new capacity in 2022. In any case, the capacity additions of 2022 surpassed the 200 GW milestone, confirming analysts’ expectations from last year. China remains the largest solar PV market worldwide and once again achieved a new historical high in new installations, with 87 GW added according to the National Energy Administration (NEA). Currently, almost 90% of polysilicon – a key material for solar PV modules - is produced in China, supporting the country’s dominant role in the solar PV market. More than 40 GW were installed in the European Union in 2022, according to SolarPower Europe, significantly above the 28 GW installed in 2021. Germany is the EU country driving most of the growth, having installed 8 GW in 2022, followed by Spain with 7.5 GW, Poland with 5 GW, and the Netherlands with 4 GW. In the US, 7 GW of utility-scale solar PV were added in the first three quarters of 2022, according to data presented by the American Clean Power Association (ACP). Although overall results are positive, the preliminary data points to a relative slowdown of the sector, mainly explained by trade barriers, high equipment prices, and ongoing supply chain constraints, that are hindering solar energy’s fast progress. The energy experts’ last estimates on new solar PV additions in Latin America revealed that 2022 might be a record year. Since 2018, the region has, every year, added more solar PV than wind, and this trend is set to continue. The strong rise of solar PV is primarily driven by the small-scale segment. The rapid expansion of the sector was witnessed in Brazil, with 2.7 GW added in 2022, according to ANEEL, and Chile with 1.8 GW, according to ACERA data. 3.1.4.2. Regulatory Framework Belgium Belgium has implemented a green certificate scheme (GC) to promote the use of renewable energy sources. Under this scheme, wind farms receive the market price for the electricity they produce, as well as additional GCs per megawatt-hour (MWh) produced. The number of GCs per MWh (kECO) for new plants' contracts was previously revised every two years. However, due to rising electricity prices, an extraordinary revision was done in December 2021\. From April 2022, onshore wind projects will receive 0.52 GCs per MWh instead of the current rate of 0.73 GCs per MWh. Given the current high pool prices, the kECO value published in December 2022 for new reservations in 2023 is 0 GCs per MWh. This means that the 7%-IRR target for such units would be already reached during their lifetime without needing any GCs on top of market revenues. This is because Belgium's scheme methodology assumes long-term pool prices forecast by inflating current FWDs values. If later on, pool prices decrease in a way that GCs are needed to reach the target IRR, the GC rate will be adjusted accordingly and become again higher than zero. The minimum price for GCs is set at 65€/GC in Wallonia. Poland In Poland, the electricity price can be established through bilateral contracts. Wind farms commissioned before 2018 are supported through a Green Certificate (GC) scheme. Under this scheme, wind farms receive 1 GC per MWh during a 15-year period. Electricity suppliers are required to comply with GC obligations and a substitution fee is imposed for non- compliance. Since 2018, wind farms in Poland are supported by 15-year two-side Contracts-for- difference awarded through auctions. Italy Prior to 2012, wind farms in operation were supported by a feed-in-premium scheme that was applicable during the first 15 years of operation. Under this scheme, wind farm operators were given a premium on top of the market price for the electricity they produced. 

Integrated Annual Report 2022 Performance Markets and regulation 059 In 2013, the Italian government introduced a new support mechanism for wind farms, known as the Contract for Difference (CfD) scheme. Under this scheme, wind farms commissioned from 2013 to 2017 were supported by a 20-year floor price, awarded through competitive auctions. Since 2017, wind farms in Italy have been supported by a new 20-year two-sided CfD scheme. Portugal Portugal has a long history of supporting the development of wind energy. Wind farms commissioned before 2006 are subject to a Feed-in-tariff (FiT) whose value is correlated with production and indexed to the Consumer Price Index (CPI). The initial tenure of the FiT was the soonest of 15 years (or until 2020) or 33GWh/MW. However, in 2013 the government introduced a tariff extension of 7 years, with a cap and floor scheme in exchange for annual payments between 2013 and 2020. This provided a level of predictability and stability for wind farm operators, allowing them to secure financing and plan for the long-term. Wind farms under the new regime (Commissioning operation date (COD) after 2006) are subject to a FiT for 20 years from COD or 44 GWh per MW installed. The tariff value is also indexed to the (CPI). Additionally, since 2019, solar projects are awarded following a new auction system. Solar PV projects awarded in the 2019 and 2020 auctions achieved record- low prices, providing a cost-effective way for Portugal to increase its renewable energy generation. Participants in the auction can choose among different remuneration schemes: a fixed guaranteed tariff structure (that was transformed into a CfD in the 2020 auction), a market scheme where players bid for a contribution made to the National Electric System, and, since 2020, a new system consisting of a market scheme for power plants incorporating a storage system, in which participants bid the value of the capacity payment what they would like to receive. Spain Under Royal Decree 413/2014, wind energy projects receive a pool price and a premium per MW in order to achieve a target return defined by regulation. In 2019, the Spanish government introduced a new support mechanism for wind farms with the Royal Decree Law 17/2019. This law has set the target return (TRF) at 7.398% for wind farms prior to 2013 for the next two regulatory periods (until 2031) and 7.09% for new installations for the current regulatory period (until 2026). The premium calculation is based on standard assets (standard load factor, production, and costs). Since 2016, all the new renewable capacity is allocated through competitive auctions. In 2020, Royal Decree 960/2020 defined the framework for a new auction mechanism. In 2021, two auctions under the new scheme (set by RD 960/2020) were held: wind and onshore PV projects competed for 12-year fixed-price PPAs with certain exposure to market prices (5% for non-dispatchable and 25% for dispatchable RES). Participants were awarded unidentified MWs but were requested to comply with stringent deadlines and submit a strategic plan. France Old wind farms in France receive feed-in tariffs (FiTs) for 15 years, with values depending on their COD and load factors achieved. In December 2016, a transitory CfD scheme was released in which wind farms having requested a PPA in 2016 would receive a 15-year CfD, with the strike price being very similar to the previous FiT. This scheme was closed in December 2019. From 2017 onwards, the French Government introduced a new set of rules for supporting wind farms: • wind farms with 6 wind turbines or less, and with a maximum of 3MW per turbine generator, can request a 20-year CfD, which strike price ranges from 72€/MWh to 74€/MWh, depending on the turbine's diameter and may include a FiT reduction when a yearly generation cap is reached. Since April 2022, an additional tip height restriction (below 132m) has been implemented • wind farms that are not eligible for the above scheme need to participate in competitive tenders in order to obtain a 20-year CfD • w new set of rules ("Cahier des Charges") that will govern auctions (both technology- specific and neutral) from H2 2021 until 2026 were published in August 2021 Romania In Romania, wind assets (installed until 2013) received 2 GW/MWh until 2017 and 1 GC/MWh after 2017 until completing 15 years. Out of the 2 GC earned until March 2017, 1 was postponed and could only be recovered gradually from January 2018. 

Integrated Annual Report 2022 Performance Markets and regulation 060 Similarly, solar assets received 6 GC/MWh for 15 years. Out of the 6 GC earned until December 2020, 2 were postponed and may only be recovered gradually from 2025. The GCs are traded in the market under a cap and floor system (cap 35.0€ and floor 29.4€). Wind assets (installed after 2013) receive 1.5 GC/MWh until 2017 and 0.75 GC/MWh afterward until completing 15 years. Solar PV facilities (installed after 2014) only receive 3 GC. Additionally, the GCs issued after April 2017 and the CGs postponed to trading from July 2013 will remain valid and may be traded until March 2032. Greece In Greece, renewable energy projects are supported by a 20-year feed-in premium (CfD) awarded through auctions. In 2022, Greece launched a new support system, based on two- way contract-for-difference (CfD) contracts, awarded through auctions. Under this system, for both onshore wind and solar installations, support will be awarded through a joint competitive tendering procedure, with minimum reserves per technology of 30%. Hungary In Hungary, renewable energy projects before 2016 benefited from a feed-in tariff scheme (“KÁT system”). In 2016, the FiT was closed to new projects and replaced by a new support system (“MÉTAR system”) consisting of 15-year Contracts-for-Difference (CfD) granted through technology-neutral tenders. United Kingdom The United Kingdom has supported the development of renewables through a 15-year two-way Contracts-for-difference (CfD) scheme, awarded through auctions, since 2013. This scheme has progressively replaced the former Green Certificate. Under the CfD scheme, "established technologies" which include onshore wind and solar PV, compete for budgets in each allocation round. Less mature technologies have a separate "pot" of the allocated budget. For the first time, in the 2023 auction, offshore will compete with mature technologies. Vietnam In Vietnam, onshore wind projects were supported under two different Feed-in-tariff (FiT) regimes. Projects were granted a 20-year PPA with EVN, the state utility. However, as the latest feed-in tariff was closed for new projects, a new support scheme is expected to be released soon, and most likely, competitive auctions will be introduced. The FIT schemes are no longer available. However, a transitional scheme has been published for renewable projects that had a FiT signed but failed to commission on time. The transitional scheme would be subject to price negotiation with EVN. Other APAC In the Asia Pacific region, many geographies enacted Feed-in-tariff (FIT) schemes in the early stages of renewables development, such as Japan, Taiwan, India, and Thailand among others. However, most of these geographies are now transitioning to other schemes, mainly auction-based systems, and are opening up to the possibility of private corporate power purchase agreements (PPAs). For example, South Korea, Malaysia, and some states in Australia are now allowing for private PPAs. Other geographies, such as India or South Korea, have opted for Green Certificate (GC) systems, although this system has not been widely used in the Asia Pacific region. An increasing number of geographies in the region are setting auctions to remunerate renewable projects, such as Singapore, Japan, China, some states in Australia, Taiwan, India, and Malaysia. USA The major update in 2022 was the passage of the Inflation Reduction Act (IRA) in August, the most robust federal commitment to clean energy to date. This new US law allocates $369 billion for energy and climate provisions, over a 10-year period, three times the current annual budget for energy. The technology-neutral tax credits and other funding will push toward the energy transition, making it easier to deploy renewable energy, build out green technologies and subsidize consumer adoption from electric cars to heat pumps. The IRA extended and expanded the clean energy tax credit system. The credit rate available for Production Tax Credit (PTC) and Investment Tax Credit (TC) can increase if labour, 

Integrated Annual Report 2022 Performance Markets and regulation 061 domestic content, and location requirements are met. If all bonuses are met, the maximum PTC value is $31.2 /MWh and the maximum ITC value is 60% of the capital expenditure. One of the highlighted provisions of the IRA that is different from past energy legislation is the domestic manufacturing credits. These credits apply to OEMs manufacturing in the US and give a 10% bump to the ITC and PTC for projects that meet the domestic content requirement. This new proposed measure led to several companies already publicly announcing intentions to bring solar manufacturing to the US. Wood Mackenzie estimates an additional 15 GW of announced manufacturing capacity by 2023, while BloombergNEF tracked 28 GW of US-based module factory new announcements in 2022. In April 2022, the AD/CVD tariff investigation was initiated, and it has been impacting the US solar developer’s market ever since. On December 2, 2022, the US Commerce Department has delivered a preliminary finding that four of the eight major solar exporters it was investigating from Thailand, Malaysia, Cambodia, and Vietnam had helped Chinese solar suppliers circumvent decade-old anti-dumping duties. However, an executive order President Joe Biden issued in June 2022, which suspended any new tariffs resulting from Commerce’s inquiry until June 6, 2024, should blunt the ruling’s impact on US solar development. Another key regulatory update of 2022 was the enforcement of the Uyghur Forced Labour Protection Act (UFLPA) on June 21 st , imposing additional restrictions on solar modules made with polysilicon sourced from China’s Xinjiang province. Its detentions began shortly thereafter, but even after several months, Customers and Border Protection (CBP) has not made major releases of equipment. The requirements to demonstrate compliance with the UFLPA are more rigorous than those for the Withhold Release Order (WRO) issued last fall. Canada In November 2022, Canada’s government proposed new tax credits for investments made in clean technology and hydrogen in its Fall Economic Statement, hoping to keep pace with the financial support provided to manufacturers in the US through the IRA. If enacted, a tax credit of up to 30% of the capital cost of investments made in electricity generation systems as well as a tax credit of at least 40 % for the production of clean hydrogen, would be made available from the first day of next year’s federal budget and end in 2035 and 2030, respectively. In Alberta, in October 2022, Danielle Smith was elected the next premier, after winning the leadership of the United Conservative Party. Part of her initial platform was the implementation of the Alberta Sovereignty Act, which would allow the province to ignore federal laws, such as the carbon tax. However, legal experts believed the Act, as proposed, had no constitutional grounds, which is likely why days after being elected she de-fanged it. While the current regulatory construct in Albert strongly supports renewables, this act and Smith’s hostile attitude towards renewable energy brings an uncertain direction for Carbon Policy & Net-Zero in this region. Mexico In April 2022, the constitutional reform to the power sector was rejected by the Mexican Congress. This proposal had been presented on October 2021 and would have granted CFE the monopoly in the electric energy value chain, taking over the regulatory activities of the industry, establishing tariffs, operating the electric dispatch, and executing the energy transition. The independent regulator of the energy sector, CRE, would have been eliminated, and the State-owned company would have acquired constitutional autonomy. There were also updates on the 2021 Modifications to the Electricity Industry Law (LIE), which proposed reforms that would negatively impact the economic dispatch logic, cancelling the Clean Energy Certificates as well as all generation permits and Purchase Power Agreements (PPA) for private market participants. In April 2022, the Mexican Supreme court declared Constitutional the modifications to the Electricity Industry Law (LIE), but it also allowed legal procedures against its application. Later, in July 2022 a federal judge granted an injunction with general effects against the LIE modification implying a return to the legal structure before the modification for all market participants. Brazil Old wind farms in Brazil receive support under a feed-in program known as "PROINFA". However, since 2008, the Brazilian government has implemented a new mechanism for supporting the development of wind energy through competitive auctions. Under this mechanism, 20-year Power Purchase Agreements (PPAs) are awarded to the winning projects. Additionally, electricity may also be sold under private PPAs in Brazil. The non-refund for solar generation curtailment caused by electrical unavailability has been an issue for entrepreneurs in Brazil, but in 2022 the National Electrical Energy Agency (ANEEL) published transition rules to calculate the compensation for the solar plants 

Integrated Annual Report 2022 Performance Markets and regulation 062 constrained-off with regulated contracts. ANEEL launched the Public Consultation nº 48/2022 to discuss the regulation for this compensation including solar plants with bilateral contracts. Considering the end of tariffs’ discounts for solar and wind power plants established by Law 14.300/2021, the Energy Research Office - EPE and the Ministry of Mines and Energy – MME released a Public Consultation to discuss the proposal for guidelines establishing environmental benefits for the power sector, including the creation of a market for carbon credits. The outcome of the Public Consultation has not yet been published. Colombia In Colombia, wind farms are awarded 15-year contracts through competitive pay-as-bid auctions. These contracts are signed with distribution companies, which guarantees the pur- chase of the energy produced by the wind farm. Additionally, Colombian wind farms must secure reliability charge contracts, which provide a monthly payment in exchange for having part of their capacity available when the system is under tight supply conditions. Chile In Chile, the government has implemented a system of technology-neutral auctions to support the development of renewable and non-renewable energy projects. These auctions award 15-year PPAs with distribution companies. Additionally, large non-regulated customers can also enter into PPAs directly with generators or organize a public auction. 5 Period of time under which the system supply goes from maximum to minimum storage, without intermediate refill, respecting some established tolerances. The critical period in hydrology is one element taken into consideration within the calculation of physical guarantees. 6 Generation Scaling Factor 3.1.5. Brazil 3.1.5.1. Regulatory Framework Regarding the power market opening, the Minister of Mines and Energy (MME) launched a Public Consultation to discuss the liberalization for consumers with less than 500kW load and voltage levels equal to or greater than 2.3kV, from January 2024, represented by retailers. Another Public Consultation was launched to discuss an Ordinance draft proposing the liberalization, in which low voltage consumers could choose their energy seller from January 2026 onwards represented by retailers (Residential and Rural Consumers Class only from 2028). The Ordinance for low voltage consumers’ market opening has not been published yet. In 2022, an ordinary review of the physical guarantee (GF) of hydroelectric power plants was made, adjusting the GF for 2023. In this process, 4 of 5 EDP’s hydro plants were eligible for the review. After the end of this process, some companies positioned themselves against the critical period 5 used in the GF’s calculation. These companies took legal action, requesting MME a new calculation for their power plants using the critical period updated. If this legal action succeeds, it may worsen the GSF 6 , negatively impacting all power plants participants of the energy reallocation mechanism (MRE). A regulatory framework was created for the development of Distributed Generation (DG) in Brazil. In summary, a transition period was established for the charge of levies over energy injected in the grid, signalling legal security and regulatory stability to this kind of investments, thus incentivizing clean energies. The main topics of this Law were: • existing installations (current model up to 2045): Mini and micro-generators already established will only pay a component of the tariff over the difference, if positive, between total consumption and energy production injected in the distribution grid, up to 2045. The waiver will also apply to new investments if access to the distributor is requested within two months after the Law’s publication. Only mini and micro-generators that require access to the grid until January 6 th , 2023, shall benefit from the levies • new installations (Tariff Transition): the Law created a transition period, of six to eight years, for the payment of distribution charges, with a gradual percentual increase up to 2028\. The difference will be borne by distribution companies through CDE. 

Integrated Annual Report 2022 Performance Markets and regulation 063 On June 27, 2022, was determined the allocation, in favour of consumers, of the amounts related to the exclusion of ICMS 7 of the database of the PIS/Pasep/Cofins 8 . This topic was object of several lawsuits. The Law established that the allocation of referred values should be made through the tariff processes of distribution utilities, as forecast and availability of credits by the Federal Revenue Service of Brazil. Later in the year it was determined that transmission concessions will be auctioned at the end of the contractual term, with the possibility of renewal only as an exception (unfeasibility of bidding or in case of any prejudice for the public interest). This Decree was preceded by a Public Consultation opened by the MME in which EDP included some contributions. Between 2024 and 2032, twenty-four transmission concession agreements will expire. It is worth noting that EDP's first transmission contract expires in January 2043. Given that 2021 was the year with the worst water shortage in 91 years, the House of Exceptional Rules for Hydro management (CREG) decided to put in motion a simplified auction, as an exceptional measure to ensure a fast thermal energy supply between 2022 and 2025\. The Simplified Competitive Procedure (PCS) was held on October 25 th , 2021. However, the hydrologic situation was much better than expected at the beginning of 2022, making it doubtful to dispatch the power plants that bid in PCS, since these contracts have, on average, much higher prices, overcharging the consumers. Furthermore, these contracts have a clause establishing the contract termination if the projects didn’t initiate the operation until May 1 st , 2022, which was the case for the greatest part of the winning projects. MME released a Public Consultation proposing a friendly termination of the PCS contracts for those who have not violated clauses that imply contract termination, without charging fines and penalties, and for those who have violated those clauses, the strict application of contractual clauses. In December 20 th 2022 was published the friendly termination guidelines. 7 ICMS – Brazilian tax on the circulation of goods and provision of services. 8 PIS: Program of Social Integration; COFINS: Contribution for the Financing of Social Security

Integrated Annual Report 2022 Performance Business area analysis 066 3.3. Business area analysis 3.3.1. Renewables Financial Analysis • Renewables EBITDA (wind, solar and hydro) increased 10% vs. 2021 to 2,528 million euros, supported by: • Wind and solar EBITDA increased to 2,157 million euros in December 2022 reflecting: (i) the benefits from portfolio expansion (average MWs installed +9% vs 2021), (ii) higher average selling price (+21% vs 2021), (iii) recovery of wind resources (+3p.p. vs 2021), namely in North America, (iv) exchange rate tailwind, namely USD and BRL (+89 million euros vs 2021), (v) and last year’s Polar Vortex in February in US, most significantly affecting the Ercot/Texas assets (c.-35 million euros); more than offset the weak performance of Hydro Iberia mainly driven by poor hydro resources throughout the year coupled with pre-hedged volumes and increased electricity prices (-37% vs. long term average in Portugal in 2022 vs. -7% in 2021), despite some recovery in fourth quarter of 2022. • Hydro EBITDA decreased 163 million euros vs 2021 to 370 million euros. In Iberia, EBITDA decrease 174 million euros impacted by the extreme dry weather in a context of very high wholesale electricity prices (total hydro production shortfall in 2022: 3.5 TWh normalized year vs. 3.3 TWh as of first nine months of 2022), despite the strong surge in hydro resources particularly in December (67% above long-term average). In Brazil, EBITDA increased +6% vs 2021 (+10 million euros) due to the recovery of hydro volumes which had a net positive impact coupled with 17% avg. BRL appreciation. Operational Analysis Hydro Generation Iberia • EDP's hydro production portfolio in the Iberia includes a total of 5.5GW of installed capacity, of which 45% includes pumping. • Hydro generation in 2022 decreased 38% year on year (-3.8TWh), to 6.0TWh, reflecting the most extreme drought in the last 90 years in Iberia, with hydro generation coefficient of 0.63 in Portugal, compared with a coefficient of 0.93 in 2021. Brazil • The Hydro generation portfolio in Brazil includes a total of 1.4 GW of installed capacity which constitutes a decrease of 0.2 GW against 2021 due to the sale of Mascarenhas power plant (Energest). The portfolio also includes 0.6 GW of equity installed capacity. • In 2022, following an improved hydrological scenario, the average GSF stayed at 86% (up from previous year’s 77%). Consequently, the volume of energy production, considering the consolidated companies, was 5,731 GWh, an increase of 5% year-on- year. € EBITDA Renewables €2,528M 10% vs. 2021 

Integrated Annual Report 2022 Performance Business area analysis 067 Wind and Solar Generation • The Group's wind and solar generation portfolio corresponds to a total of 14.7 GW of installed capacity, an increase of 1.2 GW (+9%) explained by the growth of the portfolio of EDP Renováveis (“EDPR”) net of deconsolidations resulting from the asset rotation strategy. • In 2022, EDPR added a total of 2,121 MW, including the acquisition of a solar portfolio in Vietnam (200 MW) and Sunseap’s acquisition (+402 MW portfolio of solar and solar DG assets, in several countries in APAC). • Regarding the EBITDA portfolio, EDPR added: i) 1,053 MW of onshore wind technology: 378 MW in Europe (145 MW in Spain, 100 MW Poland, 83 MW Italy, 33 MW France, 18 MW Portugal), 96 MW in Mexico and 580 MW in Brazil; ii) 597 MW of solar PV technology: 200 MW in the United States, 53 MW in Europe (36 MW Poland, 9 MW Spain, 8 MW Portugal) and 345 MW in APAC (340 MW Vietnam, 4 MW in Singapore, 1 MW Taiwan); iii) 455 MW of solar DG technology: 116 MW in the United States and 338 MW in APAC (225 MW Singapore, 44 MW China, 37 MW Vietnam, 31 MW Taiwan, 1 MW Thailand). • Following the asset rotation strategy, EDPR concluded the following sales: 100% stake on 181 MW in Spain, 172 MW in Italy, 149 MW in Poland and 260 MW in Brazil wind onshore portfolios; and 200 MW of a Build and Transfer solar project in the United States. • Regarding the equity portfolio, the variation was +15 MW on the back of Sunseap’s acquisition (6 MW Japan, 5 MW Cambodia, 5 MW Malaysia). • Wind and solar generation increased by 10% in 2022, reflecting the higher average installed capacity (+1 GW). • At the end of 2022, EDPR had 4.0 GW of capacity under construction, of which 1.2 GW related to onshore wind, 2.4 GW solar PV and 0.4 GW offshore wind. Regarding onshore wind, 188 MW were under construction in Europe (119 MW Italy, 22 MW Portugal, 20 MW Spain, 15 MW France, 12 MW Poland), 502 MW in North America (202 MW in the United States and 300 MW in Canada) and 504 MW in Colombia. Solar PV projects respect to 659 MW in Europe (193 MW in Italy, 184 MW in Poland, 170 MW in Portugal and 112 MW in Spain), 1,573 MW in the United States, and 126 MW in APAC (88 MW in Singapore, 26 MW in China, 6 MW Taiwan and 6 MW in Thailand). On wind offshore, 419 MW were under construction in the United Kingdom and 12 MW in France. Risk outlook • Renewable generation volumes: uncertainty regarding hydro generation levels, with high volatility, being 2022 an example of a year with very low production in the Iberian Peninsula; uncertainty regarding the remaining technologies with less annual volatility. • Prices of PPAs: rising trend of increase of capacity through auctions and directly by contracting corporate PPAs. • Prices for generation to market: increased price volatility in the energy market, including electricity prices, green certificates, and RECs (Renewable Energy Credits). • Policy / regulatory support for renewables: uncertainty regarding long-term regulatory frameworks (i.e., incentives, capacity, among others), as well as potential clawbacks to inframarginal technologies. • Political/social risk in EDP geographies: risk of political uncertainty and instability in EDP geographies, the most current example being Brazil, with the risk of social unrest increasing after the 2022 presidential elections. • Counterparty: possibility of counterparties defaulting on their obligations (i.e., energy sales contracts, equipment purchase contracts, among others). • Interest rates and capital gains: increased volatility of reference interest rates, impacting the expected profitability of new investments and impacting the lower-than-expected selling price of parks, leading to lower capital gains. • FX: potential evolution of key currencies leading to lower results in EUR. • Construction and asset development: delays in the allocation of construction permits and potential capex deviations and delays in the commissioning date, due to supply chain related constraints and cost increases. • Asset operation and availability: uncertainty regarding damage of assets and/ or loss of profit, risk of delays in maintenance and construction due to logistical and supply chain constraints. 

Integrated Annual Report 2022 Performance Business area analysis 068 3.3.2. Networks Financial Analysis • EBITDA from networks increased 13% vs 2021 to 1,506 million euros, mainly explained by: (i) 188 million euros increase in the Brazilian networks segment mainly reflecting the regulated revenues indexation to inflation (90 million euros), a stronger BRL (90 million euros) and a 32 million euros increase in the transmission’s EBITDA from RAP indexation to inflation and new lines commissioned which more than offset the sale impact and gains associated with the asset rotation of the transmission lines in December of 2021 (37 million euros contribution in 2021 and 46 million euros gain). In Iberia, EBITDA was broadly stable compared to 2021 as the positive impact from higher Portuguese 10Y bond yields on the return on RAB and the benefits from integration of Viesgo were compensated by a normalization of OPEX, in Portugal, and “Lesividad” provision reversal, booked in 2021. Operational Analysis Distribution Iberia • The Distribution network in Iberia reached the length of 284,733 km in 2022 corresponding to a slight increase of 1% vs 2021. • At the end of 2022, EDP reached 6.0 million smart meters installed in the entire distribution network in the Iberian Peninsula. Smart meters are aligned with the efficiency, digitalization and innovation strategies and are considered a strong bet in the Group, especially in Portugal where there was an increase of 15% against 2021. • In 2022 the volume of electricity distributed in Iberia remained flat. • The Installed Capacity Equivalent Interruption Time (ICEIT) in Portugal registered an increase vs 2021, reaching the value of 54 minutes, which is still below the regulator’s benchmark. In Spain, the registered ICEIT value was of 18 minutes, a decrease from the previous year’s value of 20 minutes. • Regarding energy losses in the network, Portugal registered an increase in the indicator (measured based on energy output from the grid) which reached 8.74% in 2022 (+0.1pp vs 2021), remaining below the upper regulatory limit of 9.25%. In Spain (measured based on energy input into the grid), an increase to 4.8% was registered (+0.2pp vs 2021). Brazil • The Distribution network in Brazil reached the length of 96,055 km in 2022, corresponding to an increase of 1% vs 2021. • In 2022, the volume of energy distributed increased 1.8%, (2.0% at EDP SP and 1.6% at EDP ES). This increase reflects the resumption of economic activity after the pandemic which still affected the initial months of 2021. • The number of new customers increased 2.6% with free customers increasing by 14.5% (122 customers at EDP SP and 118 customers at EDP ES), due to the migration of captive customers to the free market. • In both distributors, service quality indicators improved in comparison to 2021. At EDP SP and EDP ES, the Equivalent Duration of Interruption (DEC) was at 366 and 420 minutes respectively. As for the Equivalent Frequency of Interruption (FEC), it reached the value of 3.3 in both companies. • As for energy losses in the network, both distribution companies showed improvements with EDP SP reaching a value of 7.9% (-0.4pp vs 2021) and EDP ES reaching 11.9% (- 0.5pp vs 2021). € EBITDA Networks €1,506M 13% vs. 2021 

Integrated Annual Report 2022 Performance Business area analysis 069 Transmission Brazil • During 2022, the acquisition of CELG-T (now “EDP Goiás”) was successfully concluded, and a new lot (Lot 2) was awarded to EDP after placing a winning bid at the auction. • 2022 was also a year of great construction progress: the two lots that were in partial operation by the end of 2021, started fully operating in 2022\. Additionally, of the three that were under construction and not yet operating, two of them started operations successfully. • This way, by December 2022, 4 of the 5 transmission lots and EDP Goiás were in full operation (2,185 km), 1 lot was still under development (350 km) and 1 lot yet to start construction (188 km). Risk Outlook • Market price: increased price volatility in the energy market, including the price of electricity, with impact across the business in Generation, Networks (in Brazil) and Retail. • Low voltage network concessions (Portugal): uncertainty as to the timing of the launch of the tender and its terms, with possible fragmentation of the activity and increased costs for the system. • Political/social risk: risk of political uncertainty and instability in EDP geographies, the most current example being Brazil, with the risk of social unrest increasing after the 2022 presidential elections. • Counterparty: possibility of default or failure of counterparties to meet their obligations, leading to possible delays, penalties or lost revenue. • Construction and asset development: delays in the allocation of construction permits and potential capex deviations and delays in the commissioning date due to supply chain related constraints and cost increases. • Asset operation and availability: uncertainty regarding damage of assets; risk of delays in maintenance and construction due to logistical and supply chain constraints. • Business continuity: impact of extreme events with possible materialization in a prolonged interruption of operations. 3.3.3 Client Solutions and Energy Management Financial Analysis EBITDA from Client solutions and Energy Management (thermal generation, supply and energy management), increased to 486 million by: • In Iberia, EBITDA increased significantly driven by: i) In Supply, a normalization of operating conditions vs 2021, despite seasonal effects of higher sourcing costs, ii) increase in thermal generation particularly in the first nine months of 2022 and iii) the positive impact of energy management results driven by a reduction in energy prices by the end of the year and adequate management of exposure vis-à-vis regulatory uncertainty and changes during the year. • In Brazil, the segment performance benefited from: i) higher volume of electricity, ii) better optimization of the intermediation operation and iii) higher availability of Pecém thermal power plant. • Operational Analysis • Thermal Generation € EBITDA Client Solutions and Energy Management €486M 297% vs. 2021 

Integrated Annual Report 2022 Performance Business area analysis 070 Iberia • The Iberian thermal generation portfolio has an installed capacity of 4.9 GW, with most of the capacity being CCGT (59% or 2.9 GW) and coal (37% or 1.8 GW). The remaining thermal capacity is divided between nuclear (0.2 GW), cogeneration and waste. • Thermal generation increased 45% compared to 2021 (+5.3 TWh), to 17.2TWh, reflecting the response of the impact of the drought in Iberia and the increase of electricity exports to France. Nuclear generation remained stable. Brazil • In Brazil, EDP has 720 MW of installed thermal capacity corresponding to Pecém plant. • In 2022, Pecém was not dispatched due to the improved hydrological scenario. • Despite not being dispatched, Pecém’s availability stayed at 97.5%. Supply Europe • 2022 marked the most challenging year of the current century in terms of providing energy-related products and services. Wholesale energy and commodities prices soared during 2022 in response to gas supply shortage due to Ukraine-Russian conflict and sanctions taken by Western counties against Russian gas supply, which led to all- time high inflation levels in energy products and services. • The already in place Energy Transition plans were fast paced worldwide with countries and companies committing to more ambitious Net Zero targets, which resulted in higher prices and supply chain disruptions. These decisions affected directly prices and supply of solar panels and Electric Charges to face a higher demand of customers looking for green solutions and energy independence. • The high uncertainty and price oscillations led clients to go back to the regulated business. In Portugal the regulated electricity business (operated by EDP under SU Electricidade brand) increased 5% vs 2021 in number of clients to 1 million, and 20% in electricity sold to 3 TWh. • On the other hand, and in line with the regulated business exodus, EDP liberalized electricity business saw a 3% reduction in number of clients to 3.9 million, and an increase of volumes sold to 18 TWh, mainly due to the increase in large accounts consumptions vs a 2021 impacted by the pandemic and lockdowns. As a direct effect of the increase in gas products and the governmental incentive in the regulated business, • the liberalized gas business lost competitiveness, and therefore EDP portfolio of gas customers in Portugal reduced by 15% to 550 thousand, and volumes decreased by 17% to 3.5 TWh. • In Spain, EDP also registered an increase of 12% in electricity sold to 12 TWh, due to no pandemic restrictions and lockdowns, and a decrease of 14% in gas volume sold to 3.3TWh. • In the services sector, among the main traditional services, emphasis should be placed on “Funciona” portfolio, which grew by 11% to 600 thousand customers and “EDP Saúde”, which registered a total number of 220 thousand customers in Portugal, 13% more than in 2021. • Regarding the commitment and the focus on to new services more focused on efficiency and energy transition, emphasis is placed on solar DG and Electric Mobility. Even with the global supply chain disruption, EDP installed in Iberia 200 MWac, 2.4x more than 2021. In mobility, EDP installed 2.3 thousand chargers, both public and private. • Following the acquisition of Enertel in 2021 (a solar DG company in Italy), in 2022 EDP reinforced the strategy of Solar DG geographical expansion with the acquisitions of Soon Energy and Zielona, two Polish providers of Solar DG solutions. In Italy and Poland, EDP installed 32 MWac in 2022. 

Integrated Annual Report 2022 Performance Business area analysis 071 Brazil • Following the trends in Iberia, the volume of energy sold in 2022 increased by 8% to 15 TWh, with the increase coming from the liberalized B2B business. The regulated business increased 1% to 13.7 TWh. • The focus on distributed generation is also a reality in Brazil, even though it was the geography most harmed by the supply chain disruptions and installations delayed, with solar DG installations dropping from 33 MWac to 9 MWac, although the delays are planned to be executed during 2023. Risk outlook • Market price: increased price volatility in the energy market, including electricity prices, with impact across the business in Generation, Distribution (in Brazil) and Commercialization, as well as fuel prices with impact on the Energy Management activity. • Risk on thermal revenue: possibility of a fall in thermal generation spreads. • Retail margin/market share: uncertainty regarding the evolution of retail margin or loss of market share, marketing of new products and services and potential deviations in demand vs. energy previously contracted). • Political/social risk in EDP geographies: risk of political uncertainty and instability in EDP geographies, the most current example being Brazil, with the risk of social unrest increasing after the 2022 presidential elections. • Counterparty: possibility of counterparties defaulting on their obligations (i.e., energy sales contracts, energy purchase contracts, equipment purchase contracts, among others). • Operation and availability of assets: uncertainty regarding damage to assets and/or loss of profits, risk of delays in maintenance and construction due to logistical and supply chain constraints.

Excluding non-recurrent effects Recurrent EBITDA increased 21% to 4,522 million euros, benefitting from a strong growth of EDP Renováveis, Client Solutions and Energy Management recovery in Iberia and electricity networks in Brazil. • In Renewables, 10% increase vs. 2021 to 2,528 million euros. This performance was mainly driven by a strong performance of EDPR, namely due to an increase in wind resources (+3 p.p. vs 2021), higher average installed capacity (+9%vs 2021), positive ForEx impact (+89 million euros) and higher average selling prices; on the other hand, Hydro Iberia EBITDA declined 49% vs. 2021 impacted by the driest year in a century in a context of extreme high prices where expected production was 100% hedged. • In Networks, 13% increase to 1,506 million euros. Excluding one-off impacts (1 million euros in 2022 vs. 13 million euros in 2021), Recurring EBITDA increased 12% vs 2021 (+164 million euros), mainly driven by the 44% increase in networks EBITDA in Brazil, reflecting the update of revenues regulated to inflation, the start of four transmission lines, as well as the positive FX impact in the period. € EBITDA €4,524M 22% vs. 2021 

Integrated Annual Report 2022 Performance Group’s Financial Analysis 073 • Client Solutions and Energy Management amounted to 486 million euros in 2022. Excluding the one-off impacts (-6 million euros vs 2021, from net gain of 4 million euros in 2021 to net loss of 2 million euros in 2022), Recurring EBITDA increased 370 million euros vs 2021 to 488 million euros. The increase in thermal generation, as well as the positive results from energy management in the fourth quarter of 2022, and the supply normalization, more than compensated the negative impact from the largest drought in decades, that generated a -3.5 TWh deviation in hydro production vs. average, in a context of high wholesale energy prices. • Opex costs increased 21% vs. 2021 to 1,874 million euros. The tight cost control and successful implementation of ongoing saving programs, mainly in Iberia, were offset by the requirements needed to accelerate growth in renewables and EDP Góias integration. • Other net operating revenues/(costs) decreased by 298 million euros, to a net operating revenue of 38 million euros, mainly on the lower gains from the asset rotation and higher regulatory costs in Europe. • EBIT increased 31% vs. 2021, to 2,530 million euros, negatively impacted by the increase of amortizations mainly driven by portfolio expansion, impairments mainly related with thermal assets in Iberia and Brazil (335 million euros) and ForEx. • Net Financial results amounted to -910 million euros in 2022 penalized by -58 million of euros of ForEx. Net financial interests increased 32% to -726 million of euros in 2022, driven by ForEx and higher cost of debt indexed to inflation in Brazil. Average cost of debt increased to 4.4%, penalized by all currencies but mainly due to the increase in inflation in Brazil that more than doubled the cost of debt of EDP in that currency. Excluding BRL cost of debt increased ~20 bps from 2.5% to 2.7%. • Income taxes amounted to 398 million euros, representing an effective tax rate of 25% in 2022. • Non-controlling interests increased 10% to 491 million euros in 2022, including (i) 362 million euros related to EDPR, mainly explained by a better performance in projects with minorities and higher free float vs. 2021; (ii) 84 million euros related to EDP Brasil on the back of the strong growth in net profit and the impact of BRL , partly mitigated by an increase of EDP stake in EDP Brasil after buyback program; and (iii) 45 million euros mainly attributable to the 25% minority stake at the electricity networks business in Spain. • Net profit attributable to EDP shareholders reached 679 million euros in 2022 (+3% vs. 2021). This result was penalized by non-recurrent effect of -€192m in 2022, including impairment of thermal in Brazil and Iberia, recurring net profit increase 6%, to 871 million euros in 2022, driven by strong performance of networks in Brazil and renewables in Europe and a better performance of Client Solution and Energy Management despite the adverse energy and weather context in Iberia. These factors were compensated by the increase in interest costs. € EBITDA €4,524M 22% vs. 2021 EBIT €2,530M 31% vs. 2021 EBIT €2,530M 31% vs. 2021 NET PROFIT Attributable to EDP Shareholders €679M 3% vs. 2021 

Integrated Annual Report 2022 Performance Group’s Financial Analysis 074 3.4.2. Investment Activity Expansion Investments (including Expansion Capex and Financial Investments), 6,018 million euros (+80% vs. 2021) • Expansion Investment represented 90% of total investment and mostly dedicated to new renewables capacity and electricity networks (~96%). • Expansion Investment in new wind & solar capacity amounted to 5.2 billion (+77% vs. 2021), distributed by North America (38%), Europe (26%), APAC (22%) and South America (14%). • In Brazil, in local currency, Expansion Capex in transmission investments doubled while capex in distribution increased by 46% vs 2021, namely due to the acquisition of new transmission lines and grid expansion and improving quality of service in distribution. Maintenance Capex, €656M (+15% vs. 2021) • Maintenance capex amounted to 656 million euros in 2022 and was mostly absorbed by networks in Iberia and Brazil (76 % of total). The execution of our asset rotation strategy was strong during 2022: In 2022 we announced and closed several asset rotation deals, of which it’s worth highlighting: (i) a 181 MW wind portfolio in Spain (233 Million euros), (ii) a 149 MW wind portfolio in Poland (315 Million euros), (iii) a 172 MW wind portfolio in Italy (382 Million euros), (iv) the Build & Transfer Agreement of EDPR’s 200 MW Indiana Crossroads Solar in the US and (147 Million euros), and (v) a 260 MW wind portfolio in Brazil (133 Million euros). The remaining asset rotation proceeds resulted from transactions announced in 2021, which only were cashed-in in 2022. 3.4.3. Net Debt As of December 2022, net debt stood at 13.2 billion euros, 14% higher vs. December 2021, impacted by (i) a robust performance of the organic cash flow (2.6 billion euros); (ii) proceeds from asset rotations in the period (2 billion euros). This decrease was partly mitigated by our core expansion activity with the significant step up of our expansion investment (6.0 billion euros, including financial investments) and the annual dividend payment (753 million of euros).

Integrated Annual Report 2022 Performance Share performance 3.5. Share performance 3.5.1. Share EDP market price was 4.656€ per share at the end of 2022, 3.8% below the 4.838€ per share at the end of 2021. Based on the payment of dividends to shareholders held on April 6 th , 2022 (0.19€ per share), which implied a dividend yield of 3.9% (considering 2021’s year-end closing price), in 2022 EDP generated a total shareholder return (TSR) of 0.5%, assuming automatic reinvestment of the dividends received into new shares. 3.5.2. Market Performance In 2022, European Equities benchmark index, Eurostoxx 600, yielded a TSR of -11.4% significantly impacted by geo-political tensions that challenged the trend of globalization, of which the most relevant was the invasion of Ukraine which triggered an exceptional energy and food crisis across most of the world. In most developed economies, a strong surge in inflation led the central banks to sharply increase the cost of money, pressuring the assets’ real value. The Utilities Sector outperformed the Eurostoxx600 and exhibited total return of -7.1% return in 2022 as investors sought more defensive stocks during the market downturn and the setup of the European recovery plan and approval of the inflation reduction act (IRA) in the USA which is expected to strongly promote decarbonizing the economies and securing energy independence improved the renewables outlook. On the other hand, performance was affected by the increase of the interest rates as central banks tried to curb inflation. Furthermore, some energy companies were penalized by increasing energy sourcing costs caused by volatile energy markets and political intervention. In 2022, the global benchmark for clean energy-related businesses, S&P Global Clean Energy Index, registered a TSR of -4.7%, mainly driven by easing of the global congestions in supply chains and improvement of the outlook for renewables development, namely in the EU and in the USA. These factors were offset by concerns on the sustainability of renewables’ projects internal rates of return as the cost of capital increased due to higher interest rate. EDP’s TSR of +0.5% in 2022 outperformed both European and Utilities benchmark Indexes, benefiting from renewables stronger growth prospects, namely in Europe and in the US, relative regulatory stability in Portugal and recovery of the hydro conditions towards the end of the year. The performance was nonetheless hampered by concerns about the cost of debt, risk of regulatory intervention in Europe and volatile energy management results at EDP level. 3.5.3. Factors influencing the change in EDP share price The performance of EDP’s share price in 2022 was impacted by several factors. On one hand, the improvement of the macro situation on the back of the end of Covid-19’s lockdowns led to a recovery of electricity demand as economies re-opened which caught supply chains unprepared. On the other hand, the execution and strong delivery of EDP’s Strategic Plan growth targets in the first year of this plan. 076

Decarbonising the world Alignment with the SDGs Objectives KPIs 2022 Target 2025 Installed capacity of renewable origin 79% 90% Smart meters installed in Iberia 87% 100% EV charging stations 6k >40K The fight against climate change and, in particular, the fulfilment of the climate goals of the Paris Agreement, reinforced in the Glasgow Pact, has led to a five-fold acceleration in the pace of decarbonisation of the world economy. The electricity sector, through the use of renewable energies, is key to this acceleration by promoting the electrification of the remaining sectors, particularly transport, air conditioning in buildings and industry. EDP, by the nature of its activity, plays a pivotal role in this collective effort to combat climate change, an integral part of its global strategy. Leading the energy transition, contributing to a low carbon economy, has been a primary objective of the group, which is now a globally recognised reference among its peers. EDP contributes to the decarbonisation of the world economy on two different fronts: • through the decarbonisation of generation, through expansion into renewable energies and the progressive closure of thermoelectric plants • through the electrification of consumption, offering new low carbon product and service solutions. These services include: • distributed generation: installation of solar photovoltaic systems on a self-consumption basis and adapted to customers and local characteristics, including energy communities • sustainable mobility: support, advice and availability of in-home and out-of-home charging solutions currently available in Portugal, Spain and Brazil • energy efficiency: more efficient equipment and lighting, such as LED lamps, high- efficiency motors, electronic variable speed drives and heat pumps, as well as advisory services and energy audits. 

Integrated Annual Report 2022 Performance Sustainability 084 3.6.1.1.1. Renewable energy 1 North America installed capacity includes 1 MW of storage. The path to decarbonisation involves a strong commitment to electricity production from renewable sources. The 2021-2025 Business Plan emphasised the acceleration of the group's investment in renewable energy, with a planned investment of 19.2 billion euros for its expansion, which corresponds to 80% of the group's total investment in the energy transition. This unprecedented investment in renewable energy includes wind, solar and green hydrogen complemented by energy storage technologies. The Plan targets 20 GW gross added renewable capacity by 2025. On average, new gross capacity is estimated at 4 GW/year, during the period 2021 to 2025, preferably in low-risk markets with regulatory stability, favouring long-term PPA (Power Purchase Agreement) and energy purchases Contracts for Difference (CfD). In technological terms, 47% of the total planned capacity, i.e., 9.4 GW, will be allocated to solar technology, 46% (9.1 GW) to onshore wind technology, 7% (1.4 GW) to decentralised solar and 5% (0.9 GW) to offshore wind, to be carried out by the company Ocean Winds (50/50 joint venture with Engie). To increase flexibility, EDP also intends to expand its energy storage capacity beyond its traditional storage in hydroelectric plants with a pumped-storage reservoir. An increase of 0.4 GW of capacity is therefore planned for 2021-2025. The group's asset rotation continuity strategy significantly contributes to this implementation. In 2022, EDP installed 1,053 MW of wind farms and 1,052 MW of solar farms, and sold a total of 790 MW, resulting in a net addition of 1,315 MW of installed capacity. In line with the marked investment planned in renewable energies, EDP has set demanding targets, aiming to achieve full carbon neutrality (Scope 1 and 2 emissions) in 2030. By 2025, the installed capacity of renewable origin should exceed 90%, reaching 100% in 2030. In relative terms, at the end of 2022, the percentage of installed capacity of renewable origin was 79%, i.e. a decrease of 1 p.p. compared with 2021. This variation was mainly due to the inclusion of the Los Barrios power station (coal) in the consolidation perimeter. In 2022, renewable energy represented 74% of the electricity generated by the group, 2% less than in 2021. Of this 74%, wind energy represented 70%, hydro 26% and solar 4%. The slight drop in this indicator was essentially due to (1) the sharp reduction in hydroelectric generation in the Iberian Peninsula (IPH below 0.7) as a result of the severe drought that affected the Iberian Peninsula until November; (2) the sharp increase in generation from coal- KPI 2022 Renewable energy TARGET 2025 79% Installed capacity of renewable origin >90% 74% Production from renewable sources 83% 974 MW Installed capacity in centralized solar systems 5.5 GW 700 MW 1 Installed capacity in decentralized solar photovoltaic systems 3.7 GW 

Integrated Annual Report 2022 Performance Sustainability 085 fired power stations in Spain as a result of the drought and the escalating price of natural gas, also a consequence of the war in Ukraine; (3) the increase in wind and solar generation and the fact that the Pecém power station has been shut down have not been enough to compensate for previous situations. RENEWABLE INSTALLED CAPACITY (%) RENEWABLE ENERGY GENERATION (%) The decarbonisation route that the group has followed also involves the development of innovative projects, in anticipation of future business solutions. There is notable investment in areas such as energy hybridisation, which leverages potential synergies between different technologies (solar, wind, hydro and storage), the medium-term production of green hydrogen and solar and wind installations on offshore structures. In 2022, EDP completed the installation of the largest floating solar plant in Portugal, located in the reservoir of the Alqueva hydroelectric power station, with an installed capacity of 5 MWp and a battery of 1 MW/2 MWh. Also in this field, EDP secured the right to install a 70 MVA power plant on the same reservoir in the first floating solar plant tender launched in Portugal. The grid connection capacity allocated in this process should allow the installation of up to 154 MW of renewable energy, including the 70 MW of floating solar PV and, additionally, 14 MW of solar equipment and hybridisation of 70 MW of wind capacity. EDP, through Ocean Winds, has been raising its profile in offshore wind growth with 1.5 GW gross capacity in operation by 2022, around 0.9 GW under construction and a portfolio of 14 GW under development. This focus on offshore wind goes far beyond what was foreseen in PN21-25. 3.6.1.1.2. Distributed generation Anticipating the new energy paradigm, EDP has been consolidating its presence in a future in which power production, consumption and distribution will be increasingly decentralised. In this sense, the group offers a variety of solutions aimed at the specific needs of the various customer segments, through a diverse and competitive set of products and services in the solar photovoltaic field, which avoid emissions in the final consumption of energy. In addition to the suppliers in Portugal, Spain and Brazil, and the services offered in Italy and Poland by EDP Comercial, EDP Renováveis has also begun this activity: • in the United States, with the acquisition of a majority stake in the company C2 Omega, with a portfolio of 88 MWp of installed capacity and a short-term pipeline of more than 150 MWp in 16 states • in APAC, with the consolidation of the acquisition of 91% of Sunseap in Singapore, the largest decentralised solar company in Southeast Asia, with 563 MW of solar projects operational and under construction and a portfolio of 10 GW of renewable projects in different stages of development 48% 70% 72% 74% 74% 74% 79% 80% 79% 91% 100% 2005 2015 2016 2017 2018 2019 2020 2021 2022 2025 2030 20% 58% 66% 56% 67% 67% 74% 76% 74% 83% 100% 2005 2015 2016 2017 2018 2019 2020 2021 2022 2025 2030

In 2022, EDP installed a total of 256 MW of solar photovoltaic systems, both in the transactional format, with a customised installation service tailored to each customer, and in the as-a-service format, in which the investment and operation of the system is ensured by EDP during a certain contracted period with the customer. The total installed capacity amounted to 700 MW, which produced 565 GWh and avoided 300 ktCO2e of emissions. DECENTRALISED SOLAR INSTALLED CAPACITY (%) (1) North America installed capacity includes 1 MW of storage. 3.6.1.1.3. Sustainable mobility EDP has made a pioneering commitment to promote electric mobility over the next few years. The objectives now outlined are in line with the conviction that combating climate change and decarbonising the economy will involve greater penetration of renewable energies and electrification of consumption, particularly in the transport, heating and cooling sectors. In conjunction with the group's strategic objectives of achieving 100% renewable installed capacity by 2030 and reducing its specific CO2 emissions by 90% in 2030 compared to 2015 levels, we are actively contributing to accelerating the transition to sustainable mobility. EDP is committed to achieving a 100% electric fleet (light vehicles) by 2030, which will require considerable investment in the renewal of its vehicle fleet. This transition will now be accelerated and will lead to a 70% reduction in CO2 emissions from the global fleet, which consists of some 4,000 service vehicles. EDP has also committed to the installation of 40,000 public and private charging points by 2025 in all the countries where we are commercially active (Portugal, Spain and Brazil), as well as for 180,000 customers with electric mobility solutions by 2025. Within the scope of the services provided by EDP, which contribute to the decarbonisation of energy consumption, electric mobility also plays a fundamental role. Given the potential for action, the company has internalised a great proportion of its efforts in the area of electric mobility through solutions (products, services and charging networks), mostly aimed at its customers, but also in internal measures at group level. In this sphere, EDP has established initiatives to encourage the acquisition of electric vehicles by its employees, maintaining the "Electric Mobility Employee Pack" initiative, which offers special conditions KPI 2022 Sustainable mobility TARGET 2025 76.5 K Customers with electric mobility solutions 180k 14.6% Electrification of the light fleet 100% (in 2030) 6,010 Charging points installed >40k 14,7% 1,7% 8,1% 0,8% 26,5% 48,3% Portugal Spain South America Rest of the Europe North America (1) APAC 

Integrated Annual Report 2022 Performance Sustainability 087 to employees in Portugal for the acquisition of electric vehicles and the use of charging solutions. In 2022, EDP launched the "Sustainable Mobility Support Credits" initiative, which allocates an annual sum to employees for use in shared mobility programmes (excluding individual combustion-powered vehicles). In addition, EDP's approach has included the promotion of an ecosystem of partnerships and initiatives for electric mobility at international level: • EDP actively participates in Eurelectric - where it will chair the E-Mobility Working group from 2023, contributing to the ongoing discussions within these organisations for the development of business-oriented regulations and frameworks to support the transition to clean mobility • EDP is a board member of ChargeUp Europe, an association of EV charging infrastructure industry companies, which works actively on policy advocacy to promote the rapid and effortless deployment of EV charging infrastructure in Europe. EDP was the first Portuguese company to join this association • It collaborates with the WBCSD on a multisectoral programme that addresses business solutions and guidelines for the decarbonisation of mobility • It is a founding member of TDA, which brings together the 3 Cs (countries, cities/regions and businesses) as the key drivers of sustainable, low-carbon mobility - it aims to accelerate the global transformation of the transport sector to a net zero-emission mobility system before 2050 • EDP is part of The Climate group's ambitious EV100 initiative • In order to give visibility to electric mobility, EDP continues to promote the "Portugal Mobi Summit", the largest urban mobility event in Portugal for the fifth consecutive year, in partnership with the Global Media group. Products and Services The EDP group has a diverse commercial offer of products and services, particularly in Portugal, Spain and Brazil. Throughout 2022, EDP worked to make available the best charging solutions to its customers. The group focused, on the one hand, on the development of increasingly complete electric mobility solutions tailored to the needs of the growing market. And, on the other, on more competitive prices, and so progressively reaching more drivers of electric vehicles. In Portugal EDP Comercial supplies and installs charging solutions for electric vehicles through charging stations for the B2C and B2B segments. EDP Comercial has refreshed its website with relevant information to help customers overcome the initial barriers of this new paradigm of sustainable transport, including a simulator to help customers choose the best solution for their electric vehicle based on their mobility profile and home electric installation. In 2022, EDP Comercial made a huge digital transformation of the E-mobility ecosystem, which resulted in the launch of a new mobile app and web portals. The EDP Charge application allows customers to run on the public grid, at home and in the workplace. Using this new app, customers can check charger availability, run simulations of charging session costs, start and stop digitally, resulting in a new and seamless customer experience. The new EDP Charging Portals for condominium and B2B customers enable various charger management features, monitor charging sessions and take remote actions on chargers that give customers self-sufficiency and flexibility. Smart charging was also launched in 2022. It offers a more convenient way to charge electric vehicles when there is less electrical power available. As a result of exponential increases in mobility, this topic has become a major concern for customers. In terms of charging solutions for the B2B segment, the EDP Comercial platform that provides access to personalised energy efficiency recommendations and technical services adapted to the business, Save to Compete, has updated its offer with charging solutions adapted to the real needs of business customers, both for private and public access spaces, with different levels of customisation and also available as-a-service. In Spain The product MiVē, is an app aimed at the B2C segment, fully configurable by the customer through a calculator that covers all consumer needs in a single fixed monthly fee, particularly: charging at home, including the charger, the respective installation and energy consumption; 

Integrated Annual Report 2022 Performance Sustainability 088 charging away from home, at the public charging stations on EDP's public charging app (MOVE ON); and other additional services. In the B2B segment, EDP continued to invest in the promotion of the Save to Compete platform that offers the possibility of managing its charging points through MOVE ON. In this way, the corporate customer decides the conditions of access to its charging points (users, prices, etc.) and EDP manages them, subsequently returning the income generated to the corporate customer. The participating company thus obtains a potentially new source of revenue. Public charging network Teleworking and the boom in micro-mobility have significantly boosted the demand for electric vehicles and the inevitable need for charging infrastructure. In Portugal The estimated electric charging needs for the coming years indicate a demand for 20,000 charging stations by 2025. EDP has contributed positively to the creation of a vast public charging network, increasing the number of charging points in Portugal´s key locations with strategic partners (Brisa, McDonalds, Burger King, etc.). In 2022, EDP increased its number of contracted charging points by more than 70% and formed several important partnerships that resulted in more than 2,000 contracted charging points. EDP's growing network of partners, who provide space on their premises for the deployment of charging points, continues to be crucial for EV users, ensuring greater capillarity of the public charging infrastructure. It is important to note that 2022 saw the highest use of EDP´s public charging network, with over 400,000 charging sessions in Portugal. EDP leads the CEME market - the public charging market - with more than 50k customers benefiting from one of the most attractive tariffs in the public charging market. In Spain By the end of 2022, EDP accounted a total of 800 public charging stations in Spain. Agreements have been established with various organisations, such as municipal councils and service stations, but also alliances with private companies such as the Ahorramas supermarket chain, where EDPplans to install 450 charging points in 140 car parks and company offices. Together with Ahorramas, the alliance is being extended to include a large self-consumption solar project at its central platform in Velilla de San Antonio, consisting of more than 3,300 solar panels and having an installed power of 1,800 kWp, which will mean annual energy savings of 25% of total consumption at its logistics warehouses and central offices. With this installation, which will produce around 3,000 MWh annually, more than 1,650 tonnes of CO2 will be avoided. At regional level, in the Principality of Asturias, an agreement was also signed with Masymas (Hijos de Luis Rodríguez) for the installation of 20 chargers, each with a power of 22 kW, at eleven shops in the region. The Mastercard pilot project was also developed, between EDP and Efibat, in which the first 5 public charging points were set up with technology that allows customers to pay using bank cards and/or mobile phones. In Brazil After the 2021 installation of two more charging stations at the Guarulhos International Airport and nine ultra-fast charging points (one of them being 350 kW, the most powerful in Latin America), EDP Brasil started, in 2022, the installation of an ultra-fast charging network covering the entire state of São Paulo and connecting the main electric corridors in the country. This project, which should already be completed by early 2023, is part of EDP Smart's initiatives in electric mobility presented to Aneel via Research & Development, totalling investments close to R$ 50 million. 

Integrated Annual Report 2022 Performance Sustainability 089 3.6.1.1.4. Energy efficiency EDP promotes the improvement of energy efficiency throughout the value chain as an important contribution to decarbonisation, contributing to greater efficiency in the end use of energy by offering its customers low carbon products and services. In 2022, 38% of B2C customers on the liberalised market had sustainable services, such as energy efficiency, electric mobility or decentralised solar services. The aim is to ensure that we offer these services to 25% of these customers by 2025 and 50% by 2030. In Portugal, the Casa Elétrica programme continued, focusing on B2C customers, which aims to promote the change of butane or propane gas consumption to electricity, with an impact on energy consumption and safety, and in alignment with the strategy of electrification of consumption. In the corporate segment, EDP supports companies in the implementation of integrated energy efficiency services by offering solar energy, sustainable mobility and consumption management solutions. In Brazil, EDP also invests in energy efficiency initiatives, either through distribution companies, which operate in the regulated market, or through the service company EDP Smart, which operates in the liberalised market. The distributors, according to the legislation of the Brazilian electricity sector, have the obligation to apply 0.4% of net operating revenue annually in Energy Efficiency Programs (PEE) and 0.1% in the National Program of Electric Energy Conservation (PROCEL). EDP Smart offers solutions to improve energy efficiency (lighting, air conditioning) and also in the area of electric mobility and distributed generation. By 2022, the implemented measures led to energy savings of 30 GWh and 32 ktCO2 avoided. Energy efficiency services generated around 491 million euros of income in 2022, representing a 88% increase compared to 2021. The set of energy efficiency, sustainable mobility and distributed generation initiatives carried out in 2022 led to an estimated energy saving of 490 GWh, avoiding the emission of 1,755 ktCO2, including those corresponding to the sale of electricity from renewable sources, through the guarantees of origin scheme. Since 2015, the savings generated from sustainable services have made it possible to avoid the emission of 11.9 MtCO2, which represents around 80% of the 2025 target.

Integrated Annual Report 2022 Performance Sustainability 090 HISTÓRIA: PRIMEIRA MOLÉCULA DE HIDROGÉNIO VERDE 

Integrated Annual Report 2022 Performance Sustainability 091 3.6.1.2. Customer experience EDP provides energy supply and services to residential customers in the Iberian Peninsula and in Brazil, and business customers in Portugal, Spain, Italy, Poland and Brazil. In Iberia, the regulatory framework defines the separation of distribution (regulated market), supply (liberalised and regulated market) and supply in the regulated market. While, in Portugal, EDP operates in the three activities through independent companies, in Spain it is present in distribution (regulated market) and supply (liberalised market). In Brazil, in the states of São Paulo and Espírito Santo, EDP operates in the regulated market, in distribution and supply, as well as in supply in the liberalized market. In 2022, the growth in the market for solar solutions for self-consumption stands out. Although the demand for this type of solutions has increased in all countries, it is important to highlight the company's consolidation in relatively new territories through acquisitions. Such an example is the purchase of Soon Energy and Zielona-Energia.com, in Poland, and Enertel, in Italy, the later still in 2021. In the current market context, there are several events and trends that put pressure on service quality and challenge the commercial relationship with customers, of which we highlight the following: • the volatility in the energy markets that forces adjustments in price and contractual conditions and the search for solutions that favour price stability and predictability • the priority to decarbonise and adapt to climate change, through continuous technological, digital and legislative innovation • new regulatory dynamics and customer behaviour associated with decarbonisation objectives • the growing importance of energy services compared to the traditional business of selling energy • the increasing frequency of extreme events with an impact on infrastructure. As a result, transformation dynamics in the market context are changing the classic segmentation of customers, widening their diversity and expanding business opportunities and challenges. In this area, special attention must focus on trends towards the energy rating of buildings, the acceleration of electric mobility, self-consumption and energy communities, and the increase in the divide between customers with the capacity to invest in energy efficiency and customers in the state of energy poverty. The EDP group maintained its commitment to accelerating investment in commercial innovation by diversifying its portfolio of services and markets to ensure a highly satisfying customer experience through its commercial services, and excellence in the quality of the commercial relationship. Commitments that are part of the EDP’s values and culture and translated into quantitative strategic objectives. 3.6.1.2.1. Promoting sustainable consumption In line with EDP's ambition to be the global leader in energy transition, the group has been broadening its portfolio to provide consumers with products and services that enable them to contribute to a more sustainable planet. Efficient solutions and equipment To achieve carbon neutrality, it is necessary not only to electrify consumption, but also to change the way in which we consume energy, making it more conscious. In this context, EDP has at its customers' disposal a kit of energy-efficient equipment that allows consumers to use less energy but meet the same day-to-day goals. Examples are air-conditioning appliances \- which today are up to four times more efficient than traditional electric heaters - and water heaters, whose savings, in the case of solar water heaters, can account for up to 60% of water heating, among others. For those seeking an integrated solution, EDP also has the Casa Elétrica (Electric Home) service available, which includes advice, technical assessment and installation for the electrification of the home, resulting in greater levels of comfort and savings for the customer. Solar energy In a year of great volatility in the energy markets having an impact on gas and electricity prices for residential and business customers, the focus on solar energy has gained new relevance. This clean and virtually inexhaustible energy source allows customers to transition smoothly, at the same time reducing their exposure to fluctuating electricity prices and, consequently, their energy bill. EDP offers its customers a portfolio of solutions to maximise the investment and benefits of solar installation, with emphasis on a consumption monitoring system and the possibility of installing a storage battery so that the customer can use solar energy during the day or store it for later use. 

Integrated Annual Report 2022 Performance Sustainability 092 For the corporate sector, EDP is developing services tailored to the unique needs of each business, with an emphasis on the as-a-service model, in which EDP assumes the entire investment and takes charge of the installation, operation and maintenance of the power station. 2022 was also a year of growth for Solar Neighbourhoods, renewable energy communities that are democratising access to solar energy. In these neighbourhoods, producers make their space available for the installation of solar panels and the energy generated is shared among the neighbours of the community. Electric mobility EDP helps in all steps of an electric vehicle user's journey, from initial research to charging solutions inside and outside the home. In this sense, in addition to information initiatives and integrated offers for private charging, EDP has significantly increased the public charging network, having exceeded 3,000 public charging points contracted at the Iberian level by 2022\. Increasing the charger network is one of EDP's major focuses to reduce what is still an obstacle to the adoption of electric vehicles: the charging experience. With a strong and clear focus on digital and user experience, in 2022, EDP launched the new “EDP Charge”, the first application in Portugal to integrate the management of charging in public and private spaces. The app, already at 14,000 downloads, provides users with a map of charging points on the national grid, their availability and tariffs and can be used to link EDP’s Electric Mobility card to charge with 100% green energy, fully digitally, at any station on the grid, in Portugal. 3.6.1.2.2. Customer satisfaction The EDP group has made the commitment to maintain a customer satisfaction level of over 75%. This objective is monitored through customer satisfaction in their interactions with the company, the number of complaints, and through satisfaction questionnaires carried out periodically. In Portugal, in the liberalised market, a satisfaction level of 88% was achieved, an increase on the previous year. The NPS (Net Promoter Score) of the liberalised market, which measures the degree of customer recommendation in relation to the company, was 26% in B2C segment and 22% in B2B. In the regulated market, satisfaction levels reached 80%. Despite having been a year marked by volatility and rising energy prices in wholesale markets, the actions implemented throughout the year, particularly in terms of communication with customers, allowed the usually negative effects of these increases not to be reflected in the satisfaction of the end customer. In Brazil, the main indicator used to measure customer satisfaction is the Quality Satisfaction Index (ISQP), obtained through the ABRADEE Residential Survey. In 2022, there has been an improvement in the ranking (EDP São Paulo 69.5% and EDP Espírito Santo 74%). In Spain, the B2B segment recorded an average satisfaction rate of 7.5 (on a scale of zero to ten). 3.6.1.2.3. Complaint and claim management The EDP group continuously invests in the development of channels and means of handling complaints and grievances, as well as improving customer experience. In addition to facilitating conventional means of service, alternative solutions to those provided by law are made available, such as the Customer Ombudsman, the Ethics Ombudsman (see Ethics chapter) and participation in citizenship initiatives, such as the Complaints Portal. In Portugal, EDP has a Customer Ombudsman, an independent body whose role is to assess customer complaints in cases where they are not satisfied with the responses obtained from the standard system. 

Integrated Annual Report 2022 Performance Sustainability 093 RESPONSE DETAILS FROM THE CUSTOMER OMBUDSPERSON (%) In Portugal, in the liberalised market, despite the current context of natural gas price increase and integration of the Iberian CAP value, the energy supply segment recorded a significant reduction in the volume of complaints (-17p.p. compared to 2021), reaching the lowest value ever recorded. This result is mainly due to post-pandemic stabilisation, the greater robustness of business cycle processes and a less severe winter that resulted in fewer incidences of power failure and/or losses. Regarding solar energy, there was a reduction in the volume of claims, despite a significant increase in installations. This was due to the continuous improvement of sales, installation and after-sales procedures and evolutions in the performance of the smart meter replacement process and settlement activation. As for electro mobility, due to the context of strong growth of this activity, there was a natural increase in the volume of complaints, although not significant when compared with the installed number of recharging stations and CEME cards. 1 From December 2020, EDP stopped operating in B2C in Spain for the sale of electricity and gas. 2020 figure represents claims to 30 November 2020. In B2B energy in Spain, as in Portugal, the year was marked by complex changes in the energy sector that negatively affected the number of complaints. Several improvement and prevention measures were implemented, which contributed to a substantial reduction in the volume of complaints registered in 2022. In Brazil, at EDP São Paulo, complaints had a very positive evolution. In September, the decrease against the same period of 2021 was already 16%. The FER (Equivalent Frequency of Complaints) improved 22% compared to 2021 (in the period from January to August), reaching a FER of 4.04, well below the regulatory target (16). 3.6.1.2.4. Energy prices In the Iberian Peninsula, energy trading is free, and consumers can contract their supply with any trading company. In Portugal, and according to ERSE, in September 2022, the liberalised market represented around 86% of total customers and approximately 93% of consumption, in Portugal, and the COMPLAINTS UN 2022 2021 Portugal 80,247 95,427 B2B # 1,796 1,034 B2C # 77,873 93,727 SU # 578 666 Spain 1 450 921 B2B # 344 921 E-REDES # 106 n.a.

Integrated Annual Report 2022 Performance Sustainability 094 regulated market tariff is expected to be abolished at the end of 2025. Until then, liberalised market Normal Low Voltage electricity customers have the right to access a scheme equivalent to regulated tariffs and may return to the regulated market if their supplier does not provide this equivalent scheme. The average reference price tariffs for end user in Portugal, in 2022, was mostly composed of energy and supply costs (92.2%), as a result of the worsening of electricity prices in wholesale markets, with the costs of energy policy and use of networks representing, respectively, -11.2% and 19.0% of the total. In Spain, on 30 September 2022, the liberalised market accounted for 64.9% of total customers, 98.8%, in the SME segment, and 99.1% in industrial segments, and 63.8% of customers in the domestic segment. Domestic prices in Spain had an energy policy cost component of around 25% of the final tariff, while the energy and network use components represented, respectively, 57% and 18% of the total. In Brazil, in September 2022, the liberalised market represented 0.03% of total customers (30,086 out of about 89 million customers), about 34% of consumption. Since January 2020, all consumers with contracted power greater than or equal to 500 kW are eligible to migrate to the liberalised market, provided they purchase energy from renewable sources, with those contracting power greater than or equal to 2,000 kW being able to purchase energy from any source. Under Ministry of Mines and Energy (MME) Ordinance 465/2019, which set out the timetable for reducing the compulsory purchase of certain sources and opening the market, consumers with contracted power greater than or equal to 1,500 kW can, since 1 January 2021, purchase energy from any source as free consumers, with this threshold decreasing to 1,000 kW from 1 January 2022 and 500 kW from 1 January 2023. In September 2022, MME Directive 50/2022 was published, which allows consumers in the high voltage market to buy electricity from any supplier as from January 2024. In the same month, a Public Consultation was opened with a proposal for an Ordinance containing the schedule for opening the low voltage market starting from 2026, with predicted total opening by 2028, including residential and rural customers. With regard to the breakdown of the price of electricity, energy and sales costs constitute about 50% of the costs invoiced to the customer, with the costs of using the networks (transport and distribution) and energy policy corresponding to around 39% and 11%, respectively. 3.6.1.2.5. Quality of service Improving the quality of the technical service provided to customers is one of EDP's main aims as an operator of distribution networks. EDP maintains a rigorous process of monitoring technical service quality, allowing the adoption of mitigating measures when required. At the same time, additional checks and analyses are carried out at the point of delivery to customers in accordance with regulatory provisions. These procedures aim to support the optimisation of the maintenance and operation of the distribution network, focusing on improving the quality levels of service provided. In 2022, the quality of service remained high as a result of the technical teams’ commitment, a joint effort between EDP and service providers, management measures, new investments, and cooperation and dialogue with stakeholders. In Portugal, specific investments and maintenance plans in network assets, as well as modernisation projects and the automation of the AT, MT and BT networks that were developed over the last decade, have contributed to good performance in the distribution network, alongside stabilisation of the main indicators of service continuity in recent years, confirming the widespread progress that reflects E-REDES´ good performance in improving Quality of Technical Service in electricity distribution. In 2022, the distribution network was subjected to a number of unusual climatic phenomena, which included the storm in the southern region on 7 and 8 December and the Efrain depression between 11 and 13 December. In the southern region storm, the Tejo Valley, Metropolitan Area of Lisbon and the south of mainland Portugal were the regions most affected by these adverse meteorological conditions. In the Efrain depression, the entire country, with the exception of the Mondego Asset Area, was affected, with winds gusting at more than 110 km/h, impacting the national distribution network at all voltage levels. E-REDES developed an effective response to these events, having alerted its entire operational structure with the activation of the POAC-RD (Distribution Network Crisis Operational Action Plan), resulting in the strengthening E-REDES teams, the contact centre (fault communication service) and its external service providers; and the enhancement of vehicle, generator and other specialised equipment allocation. In 2022, E-REDES focused on the treatment of data already collected and made available by the various equipment that makes up the electricity network, with the clear goal of improving the operation and management of the network. Thus, was born the EasyINC. The project actioned a set of algorithms and rules for processing SCADA data in order to identify without delay a relevant set of information about an occurrence (affected phases, defect elimination time, success or failure of automatic reconnections, among others). This information allows the operation to deal with an increasing number of alarms and obtain essential information about them, ensuring high levels of effectiveness and diminishing the possibility of error. From 

Integrated Annual Report 2022 Performance Sustainability 095 an operation management perspective, it was possible to build a control dashboard that ensures aggregate information about what type of defects occur most in a part of the network, or the success rate of automatic reconnections. It is also possible to observe and monitor the behaviour of some substation assets, such as the opening time of a circuit breaker on demand when its preventive performance is required, promoting a culture of action and foresight, avoiding the failure of technical assets. Also, within the framework of initiatives to improve the Quality of Technical Service, work in the field of smart grids was intensified during 2022, with the development of projects aimed at enhancing the use of information provided by intelligent measurement equipment. E-REDES España, for the second consecutive year, stands out as a leading company in safety and quality of supply, a consequence of the investment made mainly in the digitisation of the network so that it becomes totally intelligent, and in operational efficiency, articulated through the Veja project. In Brazil in 2022, the indicators of distributors EDP São Paulo and EDP Espírito Santo remained below the regulatory limits established by ANEEL, mainly due to improvement actions and preventive maintenance. Distributors count on specific projects to improve quality indexes and are focused on remedying recurrent cuts, the improvement of internal processes and the acquisition of new technologies. In the last year, the indicators of Equivalent Duration of Interruption per Consumer Unit (DEC) and Equivalent Frequency of interruption per Consumer Unit (FEC) recorded in both São Paulo and Espírito Santo was consistently better than the limits defined by the regulator and lower than that observed in 2021. 3.6.1.2.6. Safety of products and services The safety of products and services sold by EDP represents a fundamental aspect for the sustainability of the business. Risk prevention and control of all activities and equipment is an essential organisational requirement, committed to at the highest level and adhered to by the entire group. Within the scope of energy services in EDP's portfolio, there is a set of promoted practices that foster safety for products and services, namely: • promotion of online simulators that allow solutions to be customised and sized according to each client's needs. In these offers, prior visits are made to adjust the solution and ensure that all additional interventions are considered • steps are taken to ensure that the legal compliance of all services and products is met in accordance with the regulations in force • training and supervision of all installation teams as well as the inclusion of instructions for use and safety rules made available to all customers • specific studies for safety analyses of the structure of buildings and of accessory equipment, enabling safety risks to be mitigated or even eliminated, for continuous improvement • regular inspection of assets, according to their function, type and regulation, to ensure their safe operation during their life cycle. 3.6.1.2.7. Vulnerable customers Quality of life and well-being are directly dependent on access to energy and, in particular, to quality electrical energy at affordable prices. In an increasingly technological and digital society, ensuring that everyone can enjoy this essential asset is a challenge that the EDP group places at the centre of its business strategy, for which it has established quantitative objectives (more details at www.edp.com) and a commitment to contribute to the targets of the United Nations sustainable development goals (SDG 7). EDP’s approach to customer energy vulnerability is based on three pillars: Commercial Commitments EDP scrupulously applies the service guarantees specified by regulation and which aim to protect priority customers from interruptions in the supply of energy. Priority customers are informed individually about supply interruptions that are subject to prior notice, with the minimum adequate prior notice, and have priority in the restoration of service in the event of COMMERCIAL COMMITMENTS ENERGY POVERTY ACCESS TO ENERGY Service guarantee Adapted solutions Social tariffs Energy efficiency New business Social dimensions 

Integrated Annual Report 2022 Performance Sustainability 096 breakdowns. Priority clients are health services, security forces, firefighters, civil protection, maritime and air safety, and penitentiary facilities. Similarly, for customers with special needs, with limited vision, hearing or oral communication or olfactory deficit, EDP adapts its information and communication systems and guarantees the same levels of quality of service and rights available to other customers. EDP also provides the “Safe Invoice” service, which covers situations of involuntary unemployment, temporary incapacity for work or total and permanent disability. Energy Poverty Energy poverty is associated with the inability of families to obtain the necessary energy services to ensure adequate thermal comfort, i.e., inability to heat and cool their homes adequately at an acceptable cost. The structural causes of energy poverty are poor energy performance of the housing stock and the inability of unemployed and poor families to invest in improving the energy efficiency of their homes. The social impacts of energy poverty are also well-known: deepening structural poverty and social exclusion, with significant impacts on public health. EDP argues that support for energy poor customers should be directed at solving the structural problem, fundamentally through the implementation of energy efficiency measures and the adoption of preventive measures to avoid power being cut off in response to non-payment. In line with the European Commission's guidelines, the group also advocates that this type of measure be financed, preferably by the State, as an obligation of the Social State, or alternatively supported by other consumers as a national solidarity measure. In Portugal, since 2010, legislation has provided for the application of a social tariff for electricity and natural gas, which translates into a discount in the access tariff awarded to economically vulnerable customers which is financed, in the case of electricity, by electricity producers in the normal regime and, in the case of natural gas, by the transmission system operator, distribution system operators and natural gas traders. In 2016, access to the social tariff was facilitated, with the extension of its eligibility criteria and its automatic allocation. In the process of defining the tariffs for 2022, the Energy Services Regulatory Authority estimated a number of beneficiaries of the social electricity tariff in Portugal of around 845 thousand customers, with a discount equivalent to 33.8% of the gross price of the transitory regulated market tariffs, corresponding to €121 million, of which €81 million would be borne by EDP. In turn, it estimated around 57 thousand beneficiaries of the natural gas social tariff in mainland Portugal, with a discount equivalent to 31.2% of the invoice before tax in the regulated market, corresponding to a value of 2.6 million euros, of which 220 thousand euros would be borne by the EDP group supply companies. In December 2022, the number of social tariff beneficiaries in EDP's customer portfolio was approximately 529 thousand customers for electricity and 19 thousand for gas. In addition, the support measures for customers exposed to the pandemic (unemployment, drop in household income equal to or greater than 20%, or infection by COVID-19) remained in force until 31 March 2022, cutting off electricity and natural gas supply due to non-payment was prohibited and debt payment was made more flexible, by dividing the amounts owed into up to 12 monthly instalments, with no late payment interest. In Spain, the social tariff has been implemented since 2009, covering, however, only electricity customers. The mechanism currently in force distinguishes three categories of social tariff beneficiaries, depending on their income level: vulnerable customers, with a 25% dis-count, severely vulnerable customers, with a 40% discount, and customers at risk of exclusion, with a 100% discount. However, as a result of the publication of Decree-Law 18/2022, of 18 October, vulnerable customers and severely vulnerable customers see their discounts increased to 65% and 80%, respectively, until 31 December 2023. The discounts in question apply to fixed term and maximum energy consumption. The social tariff is not granted automatically and must be requested and renewed periodically by the customer, if they meet the eligibility conditions, in particular, income-related criteria. Following the sale of the B2C commercial business to Total in December 2020, there are no social tariff beneficiaries in the customer portfolio of EDP's suppliers in Spain. From the beginning of 2022, the financing of the social tariff discount is assumed by all agents of the electricity sector value chain in proportion to their turnover, following the decision of the Spanish Supreme Court, which considered the previous model discriminatory because it only applied to electricity suppliers. The sum financed by the EDP group, accumulated to the October 2022, amounts to €14.1 million. In Brazil, the Social Tariff was implemented in 2002 and consists of a benefit created by the Federal Government applicable to low-income families. This is a discount on the tariff applicable to the residential class of the electricity distributors, which can vary between 10%, 40% and 65%, according to the consumption of each residence, up to a maximum of 220 kWh/month. Indigenous and quilombola families who meet the specified requirements benefit, in turn, from a 100% discount up to a consumption limit of 50 kWh/month. In 2022, EDP's two energy distribution companies had approximately 464 thousand customers in the social tariff (base December 2022). ANEEL provides monthly databases with the information 

Integrated Annual Report 2022 Performance Sustainability 097 necessary for distributors to cross-check the information, so that if a customer is identified as falling within the social tariff criteria, the benefit will be granted automatically. The EDP group’s contribution to protecting vulnerable customers is not limited, however, to the promotion of the social tariff and compliance with legal obligations. Voluntarily, through its Social Investment Policy, EDP also develops programmes to combat energy poverty (see chapter Voluntary investment in communities). Access to Energy This third axis is aimed at promoting access to energy for populations without connection to electricity networks, either through investments in start-ups with this theme in mind, or through the provision of an annual financing fund for accessibility to electricity projects in countries with a high energy deficit. The theme of voluntary contributions to mitigate energy poverty and promote access to energy is addressed in greater detail in the Social Investment Report of the EDP group.

Integrated Annual Report 2022 Performance Sustainability 099 3.6.2 Future-proof organisation 3.6.2.1. Ethics and compliance The EDP group assumes Integrity and Good Governance as one of its sustainable development principles, which is reflected in compliance with established legislation and ethical standards, upholding and promoting respect for human rights within its sphere of influence and ensuring governance of participatory, competent and integrity-based business. Accordingly, to contribute to its sustainability objectives, since 2005 EDP has had a Code of Ethics that establishes group-wide ethical principles and commitments applicable to all activity, complemented by other policies such as the Code of Conduct for Senior Management and Senior Financial Officers, the Integrity Policy, the Information Security Policy, the Personal Data Protection Policy, the Supplier Code of Conduct, the Code of Good Conduct for Preventing and Combating Harassment at Work, the Policy of Respect for Human and Labour Rights, which are implemented through specific procedures. In turn, there is a Compliance Management System which includes a range of policies, organizational rules and responsibilities, action plans and procedures defined at corporate level and applying to the whole group. Whenever necessary, corporate guidelines are specified by the business units, in order to meet the specific requirements of the different geographical areas and activities. 3.6.2.1.1. Ethics Ethics Office (ETH) and Ethics Ombudsperson activity in 2022 Since 2019, the Ethics Office's activity has been based on the design, management (and implementation as far as it is responsible) of Ethics Programs. Having concluded the 19-21 three-year period and with it the business ethics program aimed at strengthening the Ethics infrastructure at EDP - the program was called "Raising the Ethical Building @EDP - a new program was designed for the 22-24 three-year period whose main goal is, now, to strengthen the "substance" of business ethics in the Company's daily life - we therefore call the program "Making Ethics Real". In both programs, but with particular emphasis on the current program, one of the main objectives is the alignment of the business ethics policy throughout the EDP group, which is sought to materialize mainly through the sharing and implementation of practices in organizational matters, training, and communication. In the first year of the new program, 2022, the Ethics Office and the Ethics Ombudsperson's activities focused on increasing the Company's involvement with the Business Ethics Policy and strengthening employees' trust in the whistleblowing management process, issues whose importance became more evident because of the ethical climate survey conducted at the end of the previous year. As part of the efforts to further embed the Corporate Ethics Policy in the EDP universe, updating and revising the Code of Ethics was one of the most relevant initiatives, in which, while maintaining the essence of the Code in force, an attempt was made to update the document with new ethical topics and, as far as possible, make it more relevant and useful for all stakeholders. EDP's new strategy and purpose were incorporated, the commitment to an effective Speak Up policy was strengthened and the role of managers in exemplary behaviour was emphasized. The entire image of the document was revised and aligned with the Company's new brand. Another important action in this line of increasing awareness of the importance of Ethics in the Company's activities was the dissemination, through meetings with management, of the results of the Ethics survey conducted at the end of the previous year. This sharing, carried out in all geographies, made it possible to identify the main areas for improvement in this matter and to encourage the corresponding mitigating action plans. Similarly, training and communication in Ethics were also activities that marked the year 2022, as foreseen in the Ethics Program, having been developed several training sessions, this year mainly aimed at managers, and in which we highlight the face-to-face training "Approaching Ethics", held for about 170 middle managers, as well as the "Lead Now" sessions held for 50 new managers. In the live online version, we highlight the training, already started in 2021, on "Ethical Risks in Business", which this year reached 77 middle managers, and also 

Integrated Annual Report 2022 Performance Sustainability 100 the "Leading Through Others" session for 30 top managers at international level. The overall completion rate of these sessions was 65%. Most of this training was designed and implemented in cooperation with AESE Business School as part of the Ethics Chair held between the school and EDP. Training in Ethics for Partners remained a priority and the smart learning map initiative developed last year continued to be replicated with the main suppliers. A new e-learning solution has since been built and will be launched in the first quarter of 2023. Aware of the impact that adequate communication can have in disseminating an ethical culture, several notes on the importance of Ethics at EDP were published in the various internal channels during the year. Of special note was the global celebration, in October, of Ethics Day, as well as the publication throughout the 12 months of the year of the comic strip “Do the right thing!”, that allowed to alert employees, through a "friendly" format, to several themes of Ethics and Compliance present in the Code of Ethics. The strengthening of employees' confidence in the whistle-blower management process, a very clear recommendation resulting from the aforementioned Ethics survey, was addressed by revising the entire management model - processes, procedures, reporting channel - along with the emphasis given, namely in the text of the revised Code of Ethics in the second part of the year, to the speak up and non-retaliation policy. As such, and taking advantage of the opportunity created by the publication in Portugal of Law No. 93/2021, of December 20, which transposed into Portuguese law Directive (EU) 2019/1937 of the European Parliament and of the Council, of October 23, 2019, on the protection of persons who report violations of European Union law, EDP revisited its performance in this area, and rebuilt the entire whistle-blower management model, seeking for greater effectiveness, efficiency and quality in the instruments made available to all stakeholders and, in particular, its employees. The Ethics Office was therefore deeply involved, in partnership with the Compliance and Legal areas of EDP, and also with the Digital Global Unit, in the reconstruction of this model, which involved the redesign of processes, the drafting of new procedures and a new design of the IT support system - namely through the centralization of the multiple channels for reporting existing denouncements - and also its adaptation to the new processes created, while maintaining the same technological platform that previously supported the corporate Ethics Channel. The new model, which allows for full compliance with the legal provisions in force in Portugal, was also implemented at EDP R and constitutes an example of excellence that we believe will ensure the desired confidence of all stakeholders. Although in production since June last year, a transversal training session on the operation of the new model is being prepared. The process of managing potentially ethical contacts - responsibility of the Ethics Ombudsperson, shared in the new model of whistle-blower management with the Compliance Department regarding topics of a legislative and/or integrity nature \- followed its normal course in 2022. After analysis and if considered potentially ethical after investigation, the contacts are assessed by the Ethics Committee, which issues the competent opinions and informs the interested parties. The Ethics Ombudsperson, with the support of the Ethics Office, is also responsible for supporting the activity of the Ethics Committees of EDP S.A. and EDP R, and participating in the meetings of the Ethics Committee of EDP B. In 2022 in particular, the Ethics Ombudsperson prepared the quarterly status reports for the Annual Ethics Plan 22, as well as the Whistle-blower Management Scorecards throughout the year. 3.6.2.1.2. Compliance The EDP group undertakes to carry out its activity in strict compliance with current legislation and regulations, together with the promotion of responsible action guided by the highest standards of ethics and integrity, requiring its entities, employees and service providers who act on its behalf to conduct themselves in accordance with this commitment. EDP therefore undertakes a zero-tolerance policy for Compliance in relation to any act that fails to comply with the applicable legal and regulatory rules, based on the principles of transparency and justice, to prevent and combat illegal acts, particularly bribery, corruption, money laundering and financing terrorism, among others. To put this commitment into practice, EDP's Compliance & Internal Control (C&IC) area is responsible for promoting it by implementing a Compliance Management System in line with International Best Practice, namely with Standard ISO 37301 - Compliance Management Systems, EDP SA having obtained the respective certification by an independent entity. EDP's Compliance Management System breaks down into nine components (see image next page) 

Integrated Annual Report 2022 Performance Sustainability 101 consisting of different Specific Compliance Programmes (SCPs), as follows: (1) Integrity/Anti- Corruption; (2) Personal Data Protection; (3) Competition; (4) Prevention of Money Laundering; (5) Separation of Activities; (6) Environment; (7) Health and Safety; (8) Internal Financial Reporting Control System. This structure has harmonized the guidelines and methodologies of Compliance management throughout the organization and in different regulatory areas. The Compliance Management System, as well as the respective SCP, are continuously monitored by the C&IC and periodically subjected to internal and external audits, which may result in the identification of opportunities for improvement, considered for the purposes of improving compliance management. In this context, a global Survey was also carried out in 2022 among all the group's employees to assess their perception and position regarding Compliance issues, as well as to identify potential areas for improvement. Corruption, bribery, fraud, money laundering prevention In EDP SA, EDP in Spain, EDP Renováveis and EDP Brasil, the group has implemented a Specific Integrity Compliance Programme, which is certified according to the requirements of Standard ISO 37001 - Anti-corruption Management Systems. In this context, EDP's Integrity Policy, which also applies to its service providers, reinforces the policy of zero tolerance for corruption or bribery practices, clarifies the prohibition of facilitation payments, and details the principles related to: preventing conflicts of interest; donations and sponsorship; gifts and invitations to events; contribution to political parties; relationships with politically exposed persons (PEPs); monitoring international sanctions; preventing money laundering and combating the financing of terrorism. This policy also establishes guidelines for carrying out integrity Due Diligence with third parties. The principles and guidelines set out in the Integrity Policy are embodied in specific internal procedures, of which we highlight the following: • the integrity due diligence procedure of third parties with whom EDP has relationships, namely suppliers, business partners/counterparties, beneficiaries of sponsorship/ donations, employee candidates and other third parties, evaluating the various integrity risks (if necessary, using specialised external consultants) through analysis of possible existing legal proceedings, adverse news, involvement with PEPs, inclusion in sanctions lists, situations of conflict of interest, etc COMPLIANCE MANAGEMENT SYSTEM • the procedure for relations with PEPs, which provides for specific rules of action, foreseeing the need to record and communicate certain types of interaction • the procedure for offers and invitations to events, defining rules of action and thresholds for their award and acceptance, as well as review and approval mechanisms • the procedure for the attribution of donations and sponsorships, under which the integrity of the respective beneficiaries must be ensured, and the actual application of the support granted must be monitored 

Integrated Annual Report 2022 Performance Sustainability 102 • the conflict-of-interest management procedure establishing rules that guarantee impartiality and transparency in decision-making and to prevent misconduct or inappropriate behaviour • investigation procedure, defining the principles of action and rules to be followed in an investigation, involving five phases: preliminary analysis, documentary investigation, interviews, investigation and the release of a final report. In 2022, 6,317 (2021: 6,395) third parties were analysed under the third-party integrity due diligence (IDD) procedure. The conclusions of IDDs are attributed a rating and set out in an opinion that includes specific recommendations on the approval of the transaction, the adequacy of the contractual conditions and monitoring of contract performance. As part of its commitment to compliance, the EDP group provides various channels for making complaints, some of them global and others specific to certain matters or with a specific scope of application by company, country or subgroup, whose management is ensured by independent and impartial bodies. In this context, globally, one incident relating to corruption and bribery remained open in 2021, and 20 new cases were registered in 2022. Among the total incidents recorded, the analysis of 14 cases had been completed, by the end of 2022, of which two were found justified. These two cases triggered disciplinary actions against the contractors involved and an awareness-raising action was promoted among the respective teams. Specifically in the scope of Prevention of Money Laundering and Combating the Financing of Terrorism, in 2022 no reports were received, nor any suspicious operations identified at group level. In 2022, training and awareness-raising actions were also developed across the board to ensure the strengthening of the culture of compliance and Integrity, complemented by specific initiatives developed at local level according to the needs identified, of which the following are highlighted: • cross-cutting training "Compliance - The right way", addressing the principles and methodology of compliance management at EDP • cross-cutting training "ComplianceFLIX | How I met Integrity", with practical cases relating to the application of the procedures • monthly cross-cutting publication of comics "Do the Right Thing", illustrating principles of Ethics and Compliance. INTEGRITY DUE DILLIGENCE (# OF ANALYSED TRANSACTIONS) In terms of ongoing improvement, the following initiatives are also highlighted throughout 2022: • formalisation and public disclosure of the Corruption Risks Prevention Plan (covering all required EDP companies in Portugal) following the entry into force of the General Framework for the Prevention of Corruption • review of the whistleblowing channels and creation of new "Speak up" channels, meeting the requirements of the European Directive on Whistle-blower Protection and its implementation into national legislation • review / improvement of risk analysis methodologies and internal regulations on integrity, taking into account the changing context and continuous adherence to best practice. In this context, a total of 25,637 participations were recorded in the various sessions available (2021: 23,978), corresponding to a total of 7,445 hours of training (2021: 7,706 hours). 3 111 1 148 1 365 693 Portugal Spain Brazil EDP Renováveis 

Integrated Annual Report 2022 Performance Sustainability 103 Data protection Strict respect for privacy and protection of the personal data of its customers, employees, service providers, suppliers, partners and other stakeholders is assumed by EDP as a commitment throughout the value chain. In this context, the Specific Personal Data Protection Programme is one of the main cross-cutting programmes of EDP's Compliance Management System. This commitment is set out in the group's Data Protection Policy, which guarantees compliance based on observance of the following principles: (1) Lawfulness and purpose; (2) Transparency and Loyalty; (3) Proportionality; (4) Monitoring; (5) Privacy from the very start; (6) Responsibility and (7) Safety. These principles are embodied in the different norms and procedures across the group that guide the actions of the various group companies and that address, namely: • the Privacy by Design processes • the risk assessments of processing activities and data protection impact assessments • management of subcontractors • the response to the exercise of rights process • the handling of personal data breaches. These are complemented by specific procedures and controls defined at the level of each Business Unit for the entire life cycle of processing activities, according to their respective exposure to Personal Data Protection risks. In their relationship with customers and other data subjects, the group companies provide information on the data processing carried out, either by themselves or by their subcontractors, namely through the Privacy Policies available on their respective sites or informative disclaimers provided on data collection forms or in contractual clauses. In these documents, the EDP group entities identify, among other aspects, the purposes for which they process the data, the respective grounds for lawfulness, retention periods, if applicable, whether they share the data with other parties, as well as providing the contact details of the entity responsible for data processing and the contact details of the respective Data Protection Officer (DPO), through which the data subjects may exercise their rights in relation to the protection of personal data, request information or clarification about their data, and lodge complaints. With regard to incidents with personal data, in 2022, the EDP group entities: • received a total of 324 Customer complaints (2021: 364); and • notified the respective control authorities of three breaches of Customers' personal data in Portugal (2021: nine) and two in Spain (2021: zero) Of these, were also communicated to data subjects, one data subjects in Portugal (2021: two) and zero in Spain (2021: zero).

Whenever legally required, this Governance Model also includes the DPO. Under the Personal Data Protection Compliance programme, a total of 11,619 participations were recorded in the sessions provided in 2022, corresponding to a total of 4,374 training hours (2021: 6,158 employees/3,976 hours). In this context, we highlight the cross-cutting training, "ComplianceFLIX | The Data Protection Officer", with the staging of practical cases from different areas of data protection and special awareness raising on personal data breaches. 

Integrated Annual Report 2022 Performance Sustainability 104 With regard to ongoing improvement initiatives developed in 2022, the following stand out: • the revision and updating of the SCP Governance Model, with the aim of systematising and clarifying the main areas of intervention, adjusting some functions and responsibilities • the review process of the Personal Data Protection regulations, with a view to updating, better systematising, clarifying and streamlining procedures • the identification and implementation of improvements to the Personal Data Protection Programme Management Tool. Fair competition practices EDP promotes strict compliance with Competition rules, based on the commitments assumed in its Code of Ethics, its Integrity Policy, its Commitment to Healthy Competition and its Competition-related Specific Compliance Programme. The Specific Compliance Programme (SCP) - Legal Obligations for Competition aims to strengthen the EDP group companies' guarantees of compliance with the legal requirements in matters of competition in Portugal, particularly with regard to contracts and the performance of its employees in accordance with the highest standards of ethics, integrity and competitive compliance, contributing to the sustainability and development of the markets in which EDP operates. The SCP was approved at the end of 2019, with a focus on the EDP group companies operating in Portugal, comprising the following elements and documents: • Governance Model of the EDP group in respect of compliance with national and European community competition legislation, which establishes the relationship model, the rights and the responsibilities of the various participants who act within the scope of the SCP • EDP group's Competition Manual, which is required knowledge for employees. It contains the rules of conduct that must be followed by employees in their work, with a view to promoting strict compliance with competition law • training courses among EDP group employees in Portugal on the basic concepts of Competition, the main rules of conduct to be observed and the consequences of non- compliance with competition rules • specific e-mail address for employees to clarify any doubts they may have about the application of Competition rules • specific controls for compliance with competition rules in the different business units covered. Such controls are periodically monitored by the heads of the different business units, with the support of the Competition & Energy Policy • checklist and standard clause to ensure that contracts comply with the Competition rules. These rules also apply explicitly to EDP's participation in associations of companies • internal policies and procedures regarding the activity of the EDP group, namely in matters of wholesale and retail offers and access to networks, in order to ensure that the principles to be followed in matters of Competition are respected. 2020 was the pilot year for the implementation of the SCP in the various EDP group business units operating in Portugal, the results of which were extremely positive, with proven adherence by employees and business units to fair jurisprudence practices. The business units presented evidence of their performance in accordance with the competition rules. Since then, and based on the results obtained over the years, some opportunities for improvement have been implemented in the business units, with revisions to existing elements and new elements of the SCP approved, namely: • update of the Generation Offers Procedure • revision of the Competition Manual, with dissemination to all employees, with the sponsorship of the Chairperson of the Executive Board of Directors • new Coordination Procedure for the notification of concentration operations to the Competition Authorities • launch of a new training course in 2021 on the concepts of Competition and the main rules of conduct to be observed by employees. Two online training courses are currently available to all EDP employees in Portugal regarding the Competition rules: the course, "100% Compliant - the Competition Game", launched in 2020, and the "Competition Quiz", launched in 2021. Both training courses have had very high access rates, over 70%, and the course launched in 2020 is part of the programme for welcoming new EDP employees. At present, two legal proceedings of a competition law nature are ongoing: • in the first case, EDP, S.A. and EDP Comercial were charged by the Portuguese Competition Authority (AdC) with entering into an alleged non-compete agreement with Sonae MC - Modelo Continente. This decision was appealed before the Portuguese Competition, Regulation and Supervision Court (TCRS), which reduced the fines by 10%, 

Integrated Annual Report 2022 Performance Sustainability 105 to EUR 2.6 million and EUR 23.2 million, respectively. This TRCS decision was appealed before the Lisbon Court of Appeal. In April 2021, this court referred the case back to the Court of Justice of the European Union, which scheduled the trial hearing for November 2022\. The decision is pending • in the second case, EDP Produção is accused by the Portuguese Competition Authority (AdC) of abusing its dominant position in the secondary regulation band market, with the imposition of a fine of EUR 48 million. EDP Produção has appealed against the decision of the Competition Authority to the TCRS. This court confirmed the conviction of EDP Produção, which appealed this sentence to the Lisbon Court of Appeal in September 2022\. Even so, EDP Produção has already been judicially ordered to pay the fine by AdC even before the trial and the final decision of the TCRS. Following this process, the Ius Omnibus Association filed a citizen suit, anchored in the AdC decision, claiming the payment of compensation to all consumers in Portugal allegedly harmed. This process is suspended until a final decision is taken on the appeal by EDP Produção • the EDP group is fully convinced that in neither case were offences committed. A similar approach to preventing and mitigating practices that restrict competition is being implemented for the remaining countries, without prejudice to the codes and manuals already in place. Internal Control System for Financial Reporting (ICFR) EDP, within the scope of its financial reporting obligations, has an Internal Control System for Financial Reporting (ICFR), consisting of a model for the evaluation and mitigation of financial reporting risks, through the monitoring of the execution of control activities and the identification of potential improvement actions and their implementation. The EDP group's ICFR was developed and implemented based on the criteria established by the internal control regulatory framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO 2013") in relation to business processes and overall controls, and by the Control Objectives for Information and related Technologies ("COBIT") in relation to general information technology controls. In 2022, the ICFR mapped and monitored a total of 3338 controls that contribute to mitigating the risks in Financial Reporting, including those of fraud and information systems. Currently the ICFR is undergoing an external audit by an independent body, and since 2010 it has been considered, in all materially relevant aspects, an appropriate and effective internal control system and is certified by the external auditor without conditions and comments. 

Integrated Annual Report 2022 Performance Sustainability 106 3.6.2.2. Communication and transparency 3.6.2.2.1. Responsible political involvement Representation of interests EDP group institutional engagement and external affairs are managed in accordance with legal requirements and in line with the principles of action established in the Code of Ethics, Integrity Policy and other internal provisions of the Company governing its relations with stakeholders, in particular those of integrity, transparency and responsible political involvement. EDP is now preparing a Policy of Representation of Interest, to be enforced in 2023, but has throughout its activity followed its principle of responsible political involvement: It prohibits any contribution or association of the EDP brand to political parties, candidates, political campaigns/candidacies or to related people or entities. This covers the direct or indirect delivery of goods or provision of services on behalf of, or representing, EDP. It also includes the prohibition on using EDP resources for actions related to political processes. None of the group’s companies have made monetary contributions or contributions in kind to political parties, although permitted in some of the legal regimes in countries where the EDP group operates. Nevertheless, EDP participates in public decision-making processes, and engages in activities with various national, European and international institutions, with a view to conveying to public bodies their legitimate interests and/or those of the sector, which it considers worthy of consideration within the scope of legislative processes. These activities include: 1\. Awareness of specialized people and institutions EDP Renewables undertakes awareness activities for specialized individuals and institutions according to local legislation. In addition, and in accordance with US law, and at the request of US employees, EDP Renewables North America (EDPR NA) provides duly regulated mechanisms for the participation of employees in political processes and has established a policy action committee (PAC) called "EDPR NA PAC". The EDPR NA PAC is funded entirely by voluntary personal monetary contributions made by members of the PAC, who are employees, according to US law. Decisions on which political campaigns to support are made with the approval of the PAC's Board of Directors, whose members are elected PAC members, also in accordance with US law. The activities representing the interests of EDPR mainly involve the following awareness- raising initiatives, presented below which exclude the amounts under EDPR NA PAC. • Contributions to America Energy Action activities EDP Renewables North America contributes to the activities of America Energy Action, a social welfare organization established under Section 501(c) (4) of the US Federal Internal Revenue Code. This type of organization can legally participate in political activities by defending or opposing candidates for public office. However, these kinds of activities must be absolutely independent of specific candidates or campaigns: they can be undertaken for ideas, concepts or public interests. • Contributions to Non-Governmental Organisations (NGOs) EDP Renewables North America works with a number of organisations with social or environmental objectives, pursuing goals aligned with support for decarbonisation and the transition to a low carbon economy. This type of organisation can support a candidate with its own funds, but its communications cannot be coordinated by a political party, campaign or candidate. • Procurement of lobbying services EDP Renewables North America has lobbying consultants operating with the US Government and in some US states. These political consultants are prohibited from making contributions to candidates or political parties and campaigns on behalf of EDPR NA, to ensure that their activities never violate the prohibition on making political contributions, established with the EDP group. 

Integrated Annual Report 2022 Performance Sustainability 107 2\. Participation in the main European or international Sectoral or Industrial Associations During 2022 EDP sought to raise awareness among the various stakeholders in the context of the European institutions (European Council, European Parliament and European Commission) on a number of issues central to sustainability in the field of energy, either proactively or as part of public consultations. The Energy Crisis brough upon by the Russian invasion of Ukraine enforced public European discussions on Market Design and Permitting, that revealed EDP group’s commitment within the main European sectoral associations, in particular Eurelectric, WindEurope, Solar Power Europe ChargeUp Europe, European Distribution System Operators (E.DSO) or the European Federation of Energy Traders (EFET). At the same time, to promote the development of the energy sector, its sustainability and efficiency, EDP strengthened alliances with similar parties to establish macro platforms for joint public positions that reflect the vision of the sector as a whole vis-à-vis the major decarbonisation commitments undertaken internationally. In this context, the following are of note, i) the argument for putting the development of renewables as key to guarantee the EU’s energy independence, ii) the letters sent to European Commission representatives, for example supporting the RePowerEU plan and its objectives; iii) the various initiatives advocating for the publication of the Green H2 Delegated Act in order to materialize a clear framework for the development renewable hydrogen; and iv) the multiple contacts with decision-makers in different institutions seeking to contribute to opinion-forming and communicating the Company’s views on such wide-ranging and decisive issues as the Market Design, Permitting, European Funds, and Biodiversity. Membership and activity undertaken in global associations such as the World Business Council for Sustainable Development group (WBCSD); the joining at Partner level at the World Economic Forum, or at European level such as Eurelectric, or yet at national level, in the different geographical areas, such as the Portuguese Association of Electricity Sector Companies (Elecpor), the Spanish Association of Electric Energy Companies (Aelec), The Brazilian Association for the electrical grid (Abradee) , The North American Solar Energy Industry Association, The American Energy Action, the Transport Decarbonization Alliance and others, clearly identify the shared and constructive path that the EDP group continues to build, advocating sound climate action, world sustainability and security, all aligned with EDP’s Human and Labor Rights Policy. Advocacy to combat climate change Active participation preparing the COP27 in Egypt; the UN Compact continuous work pursuing the EDP all green by 2030 commitment; the preparation of Davos Annual Meeting in themes like CyberSecurity or Solving for net zero through industrial Clusters, or yet the Hydrogen Acceleration, built up to behaviour and positioning commitments among energy utilities in all of these fronts, fulfilling the corporate strategy on leading the energy transition, by creating superior value on a path aligned with the ambition of the Paris Agreement. The persistent advocacy in all representations of the Climate positioning, following the Paris Agreement as stated throughout EDP’s policies and public commitments, is mapped in the group’s Strategy, mirroring the transparent, scrutinized, and constructive positioning of the EDP group's growth. The 2022 commitment towards a NetZero planet can be identified at the 74% of the TOP20 external representation being relevant and involved work on Climate position Organizations, through an investment of 2,5 million euros. From our selected TOP20 representations of interest, 98% of the work was taken through Business or Sectoral Associations, and 2% through lobbying. 3\. The direct or indirect Involvement of employees appointed/designated for this purpose At European level, the transparency of lobbying activities carried out by appointed lobbyists is ensured through the publication of their activities in the European Union Transparency Register, a public register in which organizations representing specific interests in the European Union register and provide up-to-date information on these interests. Internally, EDP group has developed a Stakeholder Relationship Policy, with the definition of principles and guidelines for interaction with strategic groups, in particular Employees and Politically Exposed Persons and, based on four guiding commitments: Understand, Communicate, Trust and Collaborate. There is also an internal compliance platform for registration with PEP; another to record actions and contacts established (TRUST) and a shared map of EDP's external representations in society. 

Integrated Annual Report 2022 Performance Sustainability 108 Value of the activities of representation of interests For the year 2022, the costs of representation of interests were around 6 million euros and related particularly to the decarbonisation of the economy, electric mobility, energy efficiency and security of supply. Facing the energy crisis and dealing with the European Market Design were strategic focuses, bringing Renewable Energies as key to guarantee Independence. The focus of advocacy work with the main national energy sector associations (UNESA, Eurelectric, American Wind Energy Association and TDA), above all, concerned matters related to the European Green Deal and market design, the National Climate and Energy Plans of the member states and biodiversity as a whole.

Tax transparency The fiscal footprint of the group EDP is a utility present in 29 countries, the value chain of which includes the activities of production, transportation and distribution and sales of energy. These activities involve various types of taxes, levies and financial contributions which, when considered in a global manner, determine the level of taxation to which the EDP group is subject. Of all the phases in the EDP value chain, its energy production activity is the one that contributes most significantly to the payment of taxes and other contributions. Global contribution of the EDP group In 2022, the EDP group's overall tax contribution to the public revenue of the various countries where it is present amounted to around 3 billion euros, of which 891 million euros corresponded to taxes and contributions borne (paid) by the EDP group and 2.1 billion euros to contributions to the State on behalf of other economic actors, as seen in the charts: TAXES BORNE (PAID) BY THE EDP GROUP, BY GEOGRAPHICAL AREA TAXES BORNE (PAID) BY THE EDP GROUP, BY TYPE OF CONTRIBUTION 39% 18% 15% 7% 11% 10% Portugal Spain Brazil USA and Canada Romania Other (23 countries) €0.9 billion in 2022 25% 40% 17% 8% 10% Corporate Income Tax Specific taxation on the energy sector (includes CESE) Social security contributions payable by companies Property taxes Other €0.9 billion in 2022

Considering the set of taxes that are the burden of the EDP group, the most relevant tranche (34%) concerns specific taxation on the energy sector (including the windfall tax paid in Romania and Italy and the Extraordinary Contribution to the Energy Sector in Portugal - ECES), followed by income tax (24%) and, finally, social security contributions borne by companies (17%). As regards income taxes, in the main countries in which it operates, the EDP group is subject to nominal rates of taxation varying between 16% in Romania and 31.5% in Portugal, adding municipal and state surtaxes to the nominal rate in the case of companies located in Portugal. In Portugal, taxes borne (paid) in 2022 amounted to 352 million euros, essentially underlining the burden of specific taxation for the energy sector, of which 52 million euros refers to the ECES, and 74 million euros of social tariff. To these amounts should be added 77 million euros of social security contributions payable by the companies and 92 million euros relating to other taxes and levies. With regard to taxes collected by the EDP group and delivered to the states where it carries out its activity (third-party costs), this value rose to 2.1 billion euros in 2022, mostly associated with the collection of excise taxes (e.g.: VAT). Specific taxation for the energy sector in 2022 In the context of energy emergency and with a view to tackling high energy prices, Council Regulation (EU) 2022/1854 of 6 October 2022 (Regulation) came into force, which provided for, among other things, the introduction of price cap mechanisms for market revenues obtained by electricity producers from, essentially, renewable energy, and a temporary solidarity contribution applicable exclusively to companies active in the crude oil, natural gas, coal and refining sectors. Although the rules contained in this Regulation are aimed at creating standardising measures in the European Union in response to rising energy prices, certain countries where the EDP group is present have introduced unilateral measures, giving rise to the payment of windfall taxes in Romania and Italy, amounting to approximately 95 million euros and 9.5 million euros respectively. 39% 34% 24% 3% Portugal Spain Brazil Other (26 countries) €2.1 billion in 2022 

Integrated Annual Report 2022 Performance Sustainability 110 Nevertheless, based on the set of countries where the EDP group operates, Portugal continues to be the one with the highest level of energy taxation, both in the number of taxes and in amounts collected, having represented, in 2022, a charge of 176 million euros, as presented here: • The social tariff consists of a discount on the electricity bill allocated to economically vulnerable consumers, the number of which has been extended over time, and which is fully financed by ordinary electricity producers. In 2022, the amount borne by the EDP group in this respect amounted to approximately 74 million euros SPECIFIC TAXES AND CONTRIBUTIONS ON THE ENERGY SECTOR BORNE (PAID) BY THE EDP GROUP, IN PORTUGAL, IN 2022 • In 2022, EDP group paid 51.5 million euros by way of ECES. This tax is on the net assets of the production, transport, distribution and marketing of electricity • The mechanism to restore competitive balance between electricity producers operating on Portuguese territory and electricity producers operating in Spain (known as clawback) was created following the introduction of the Impuesto Sobre el Valor de la Producción de la Energía Eléctrica in Spain. The latter was suspended in Spain during 2022, and Portuguese legislature also provided for the suspension of clawback for the same period. However, the chart shows an amount paid of approximately 36 million euros, which corresponds to payments for the years 2019 and 2020. 29% 4% 20% 3% 42% 2% CESE Wind Energy – Rents Paid to Municipalities Clawback Rents of Energy Power Plants Social Tariff – Electricity Other €176 million in 2022

Transforming our Business Alignment with the SDGs Objectives KPIs 2022 Target 2025 Investment in R&D+i 289 1,000 M€ Investment in digital 532 1,000 M€ 3.6.2.3.1. Digital transformation EDP's Digital Global Unit (DGU) has the mission of defining a global technological strategy and vision for the group, making EDP a truly digital organisation, integrating digital technology into its business domains and transforming the way it works and delivers value. In 2022 the DGU progressed to version 2.0, with a new organisation guided by three main objectives: (1) more global focus, enhancing an integrated and transversal approach to all the group's regions, (2) more digital, accelerating a digital transformation focused on value creation, and (3) closer to business, strengthening the partnership relationship with the different business platforms. The energy transition imperative has a profound impact on the energy sector along the value chain, requiring both an increase in electricity consumption in the final energy consumption mix and an increase in renewables in the electricity production mix. These two conditions imply not only a change in technology and customer behaviour, but also a more robust integration of energy systems, only feasible through a true digital transition. In this context, digital transformation plays a key role in the Energy Transition - digital transition technologies such as Cloud, Big Data & Analytics, Artificial Intelligence, IoT, AR/VR and Blockchain will be key for the energy sector in its energy transition journey, as enablers and also as accelerators. In this way, digital transformation is a central part of the EDP group's strategy and is fundamental to achieving the ambitious commitments of the 2021-25 strategic plan and EDP's vision of leading the energy transition. Therefore, EDP has committed to invest a total of €1 billion CAPEX in digital transformation in the period of the present strategic plan. Digital transformation at EDP is based on three key points: • digital strategy, setting priorities for digital transformation and ambitious targets in close collaboration with the business, and monitoring developments with an integrated overview • digital products, accelerating the digitalisation of business with the introduction of new technologies and digital tools, which create value for all EDP stakeholders • digital culture, driving the adoption of new, agile and collaborative ways of working, and the attraction, development and retention of talent. EDP's digital transformation is transversal to all businesses, and to all its people, processes and tools. In addition, it has a transversal contagion effect on the group's wider stakeholders ' ecosystem, with special emphasis on the digital acceleration of partners and suppliers, in Portugal and in the different countries where the group operates. Digital Strategy To steer the group towards the intended digital transformation, ambitious objectives have been set in the group's various business and operating strands, reflected in the group's digital KPIs. By 2022, some of these Digital KPIs have already reached the goal set for 2025, according to: The levels achieved by these digital KPIs reveal EDP's robust digital performance, which has allowed the group and its businesses to reach high levels of digital maturity, according to the annual assessment carried out by external entities. In 2022 the digital roadmaps of each group platform were also updated, defining a digital ambition both at group level and for each business, prioritising and giving visibility to a group of digital initiatives focused on accelerating value creation.

As of mid-2020, and the current digital product portfolio of Digital at EDP covers four distinct typologies, depending on their duration and scope, namely: • digital boost: integrated and transformational solutions, which promote significant changes in organisation, processes and ways of working, of entire areas (development >6 months) • MVP (Minimum Viable Product): solutions, based on Agile methodologies, that deliver a tool ready to operate with the necessary and sufficient functionalities for the business in a short period of time, and that can be subsequently scaled (development 3-4 months) • scale-up: solutions that allow a previously delivered solution to scale up with additional functionalities, integrations and/or scope, boosting the adoption and impact of the original solution, as in the case of MVP, for example, (development <3 months) • quickWin: agile and pragmatic solutions that solve a business problem by leveraging standard tools like Office365, PowerBI, MSTeams, PowerAutomate, or new ways of working, like Virtual Communications, Design Thinking (development <1 month). In 2022, EDP focused on delivering more global solutions, transversal to the group's different businesses and regions, leveraging synergies, opportunities and efficiency, with more than 100 digital products having been delivered to the business during this year, of which we highlight: • Digital4Vega: a solution that uses artificial intelligence to predict vegetation growth near the power grid, supporting the identification of necessary interventions • trading decisions tool: analytical models to support renewable energy traders' decision- making in scenarios of uncertainty or volatility, reducing the associated risk • documents & files security: cataloguing, cleaning and migrating ~120TB of files to the cloud, boosting security and employee productivity • due diligence automation: automation of the Due Diligence process, ensuring compliance with the procedure established by EDP in alignment with the money laundering law • EDP Yes (You Empower Society) website: independent website for the presentation of all the group's social investment projects and respective content management • analysis of the proximity of fires to power lines: solution for monitoring fires close to power lines, triggering the dispatch of a team to the field to assess/prevent damage to assets and the population • customer communications' centralized management: application for centralized management of customer communication templates and massive change management, making communication with customers clearer and more effective • fleet Management Tool: mobile application that allows employees to book service vehicles, including the possibility of "offering a lift", reducing the environmental impact of corporate travel. Digital Culture Digital transformation is only possible with the change of the organisation itself, implementing a digital culture common to the entire group, materialised in the adoption of new ways of working and a digital mindset by all employees. For the implementation of this digital culture, in 2022, EDP stepped up the pace for developing different digital communication and collaboration initiatives, such as: • digital talks and clinics (seminar): interactive sessions in online format, to increase knowledge on digital topics, with 66 sessions having been promoted in 2022 that addressed topics such as artificial intelligence, cybersecurity, blockchain and automation and that made known some projects developed in the EDP group • DGU Weekly: w weekly newsletter sharing the main events and progress made at digital and technological level in the EDP group by DGU • Digital Global Community: virtual community that promotes collaboration and sharing of knowledge and experience on digital technologies and methodologies (e.g.: IoT, AR/VR, Blockchain, Agile), currently with over 1,700 members The creation of this Digital Global Community resulted from the strategic review carried out in 2021 on the positioning and objectives of the 9 Virtual Communities developed in 2019, which led to 4 Global Communities being launched in 2022, including this one dedicated to Digital. The launch of this new Community - part of initiative #21 of the Changing Tomorrow 

Integrated Annual Report 2022 Performance Sustainability 113 Now... With You programme, which is part of the strategic axis Future proof organisation - developed by the Digital Global Unit (DGU) in partnership with P&OD, aimed to bring together employees with high knowledge and experience in the digital area, as well as those with an interest in increasing their knowledge of the topic, promoting a more global, agile and efficient company. New dynamics were created in the communities that, combined with the pre- existing ones, contributed to an increase in participation. Within the scope of digital training and upskilling, training is a decisive element in the development of the employee's digital skills. In 2022, EDP continued to strengthen the diversification of its training offer in digital topics, complemented by informal on-the-job and collaborative learning. In addition to the focus on e-learning courses produced in-house, this year the offer was enriched with the subscription and availability of the Udemy platform, reinforcing the democratisation of access to content in self-service format. The training offer of digital content, provided by EDP University with the support of the DGU, addresses themes such as Digital Transformation, new ways of working, Design Thinking, Cloud, AI and advanced analytics, among others. In 2022 there was a high level of performance in digital training: 9,095 employees of the current staff were trained in digital topics, and during the year 31,239 hours of training were given, of which 95% were given in remote formats (live online or e-learning), providing increasingly flexible and global learning. At the same time, EDP has been strengthening its focus on training group employees in the use of collaborative and productivity tools, which are increasingly essential in a hybrid working model supported by technology. Externally, EDP also has a proactive presence in international forums on digitalisation, such as participation in Eurelectric working groups (e.g.: Digitopia Working group), where it contributes to the sharing of best practice and promotes the development of the electricity sector at European level, and leadership and participation in R&D projects in the sector, critical to its transformation and digitalisation (e.g.: www.e-redes.pt/pt-pt/transicao- energetica/projetos-europeus/euniversal). Additionally, EDP also participates in initiatives that promote digital transformation and inclusion, of which we highlight Digital with Purpose and MUDA. • Digital with Purpose After EDP joined Digital with Purpose (DWP) in 2021 - an initiative of the Global Enabling Sustainability Initiative (GeSI), whose main objective is to promote the progress of the technology industry combined with sustainable practices - it participated, in 2022, in the DwP Assessment. EDP's result in this evaluation allowed for an increase of one level in the classification attributed by this organisation in comparison with the previous year. Additionally, EDP sponsored and actively participated in the DwP Global Summit 2022 event, held in Lisbon on 23 September 2022. • MUDA The digital projects developed for the different EDP group business units resulted in the creation of a number of products contributing to the digital inclusion of customers: Making services available online, electronic invoicing, interaction through mobile applications and attendance by virtual assistants are some of the products that improve service efficiency and speed, as well as customer satisfaction. EDP has been a partner of MUDA – Movimento pela Utilização Digital (Movement for Digital Utilization) since its launch in 2017. Promoted by several private entities and the Portuguese State, it has merited recognition from the European Commission since 2018, under the DESI (Digital Economy & Society Index), namely for the actions it developed to enable all citizens to have access to information (i.e., reducing information-exclusion) and benefit from digital transformation through the acquisition and development of digital skills (inclusive and participatory). 

Integrated Annual Report 2022 Performance Sustainability 114 In 2022, the following themes, developed or supported by MUDA, in which EDP actively collaborated, were of note: • digital and social inclusion with democratisation of internet use in Portugal, including: (1) The "EUSOUDIGITAL" Programme to increase the digital literacy of adults in the use of the Internet, through 175 centres and +5,000 volunteer mentors; (2) "MUDA NUM MINUTO" Programme on RTP1, RTP3 and Antena1; (3) "Chave Móvel Digital para todos" Programme extended to services in companies, with EDP being a pioneer • Encouraging the use of online business and state services with "MUDAR É GANHAR", including: (1) Activation of more than 1M codes with the participation of 1.5M people, offering +5,700 prizes in 5 months of the contest; (2) EDP's contribution with +127k codes activated (top 3), +86% vs. the previous year, and award of ~1,200 prizes • EDP's active participation in the Digital First Initiative, with the aim of guiding the determination of targets and public policies for the Digitalisation and Administrative Modernisation of Portugal that will enable a Digital First economy and society to be built. The results of this initiative will be presented at a conference in March 2023 • Promotion of EDP initiatives on the news portal MUDA EM CASA, in which articles were published on EDP Services such as Planeta Zero EDP, NOS and EDP together for a greener future and how to optimise energy consumption, with the help of EDP. 3.6.2.3.2. Innovation Overview Innovation has long been a traditional investment priority for EDP, with EDP Inovação (EDPI) as the key promoter for innovation within the group. It was established in 2007 with the objective of creating an autonomous entity responsible for internal innovation activities as well as fostering stronger links with the entrepreneurial ecosystem. EDP's innovation operating model is based on a fast adopter logic with a well-defined purpose of accelerating new businesses with impact and promoting the rapid adoption of innovative solutions to lead the energy transition. It seeks to solve the energy transition problems through the integration of new technologies, processes, and products, as well as innovative business models in EDP´s business to enhance competitiveness and create value for stakeholders. EDPI follows an Open Innovation philosophy that engages and promotes adoption through three innovation paths that act in parallel and complementary to one another, fed by a transversal sourcing process, namely: internal delivery (innovation portfolio developed internally), external partnerships through the open innovation ecosystem (start-ups, corporates, universities, among others), and external investments through EDP Ventures. INNOVATION STRATEGY TO BE DELIVERED THOUGHOUT 3 INNOVATION AVENUES These innovation avenues are supported by the right funding and investment, coordination, and expertise development to ensure EDP is at the forefront of market trends and innovation. EDPI also ensures the development and management of the infrastructure to disseminate innovation culture and best practices across the organization, fostering both entrepreneurship and intrapreneurship. EDPI focuses on seven (+one) innovation domains aligned with corporate strategy and market trends, which positions EDP along the energy industry value chain. • Renewable energies, their integration and flexibility, to help EDP achieve its renewable energy targets • Networks, an enabler of the energy transition • Distributed energy systems that support B2B and B2C customers in developing their distributed generation solutions • Green hydrogen to support the energy transition in sectors whose activity is preponderantly dependent on carbon-emitting solutions • Energy storage and flexibility, which tests new storage technologies, flexibility management 

Integrated Annual Report 2022 Performance Sustainability 115 • Sustainable mobility, which supports EDP customers in their transition to electric mobility and provides associated services • Decarbonisation of energy uses, which supports EDP customers' decarbonisation efforts by developing new solutions and speeding up their adoption • Moreover, EDPI continuously searches for new solutions. The “Open Box” domain creates space for ideas/projects to be developed that do not fit rigidly into any of the other domains. 2022 in summary Last year marked an important milestone at EDP in innovation: Following the definition of the innovation model last year, 2022 was a year of consolidation. EDPI aligned and prioritized its opportunity spaces along its domains for greater team focus and also reinforced its team to start delivering the first opportunities within the innovation funnel. 2022 also marked the return of the face-to-face events, with editions of the Free Electrons and Energy Starter, in Chicago / São Paulo and Oviedo, respectively, and a large presence of EDP teams at the Web Summit taking the Innovation at EDP and its message to the largest global Innovation and Technology conference. In terms of investments, this was also a particularly exciting year, with new portfolio companies totalling ≈€14 million invested. Overall, 2022 was a very important consolidation year, setting the stage for the ambitious goals for the forthcoming years. Internal delivery This was the first year of the new internal incubation process, developing an internally sourced portfolio (though internally and externally scouted), supported by a de-risking funnel from opportunity to scale-up solutions & businesses, aligned with EDP strategy and priorities. 20 new emergent business opportunities (EBO) were submitted for evaluation of a global innovation decision committee. Based on its merit to move-forward, and competition for resources between opportunities, 11 EBOs were selected. Out of these, three were later stopped at the Validation phase and today eight impactful projects are moving on. 2022 set the stage for a business scale-up expectation already in 2023 with two projects in the build phase. Below are some of the projects in the funnel: • in the validate phase - The Automating PVs Installation project – with the objective to incorporate advanced solutions to automate critical construction tasks of utility-scale solar PV power plants. Relevant cost savings can be achieved by a mindset shift of the installation process from construction to manufacturing • in the build phase - The Going Net Zero project – with the objective to help C&I customers to decarbonize by a digital platform able to offer fully automatized one fits all emissions assessment and reporting with advisory-based service, able to prescribe detailed reduction plans. All these 11 EBOs involved six different EDP business units and more than 100 people across geographies. 

Integrated Annual Report 2022 Performance Sustainability 116 Open ecosystem The year 2022 represented a return to the execution of Open Innovation programs in face-to- face format, particularly the Free Electrons (founded by EDP, it is already in its sixth edition with a total of +4,000 start-up applications and +$80M investment) and Energy Starter programs, with execution in multiple geographies, as well as the carrying out of pilot projects with start-ups. Among the multiple programs in which EDP was involved in 2022, there were +1,000 start-ups evaluated, +100 meetings to explore opportunities with start-ups and nine pilots started with new solutions and technologies. • In 2022, two face-to-face events of the Free Electrons programme were held in Chicago and in São Paulo. In São Paulo, EDP was the main host, receiving 15 start-ups, more than 30 intentions of pilots, five of which are pilots with EDP. There was also an open day of the Program with an exposure to the Brazilian ecosystem of Free Electrons projects and initiatives, involving more than 150 participants in person and almost 500 digitally • During the year, the Energy Starter program was restructured in line with EDPI´s recent innovation model and corporate strategy, comprising three verticals: Grids, Renewables & Green Hydrogen, and Customer Solutions. Within Grids and Renewables & Green Hydrogen, the first session took place with four pilots approved, as well as a face-to-face bootcamp in Oviedo. Sessions on Customer Solutions are expected for 2023. The Energy Starter program engaged more than 100 people from EDP in multiple geographies and business units • From the pilots kicked off in 2022 the most remarkable ones are with Power to Hydrogen, a US-based start-up focused on electrolyser technologies, that kick off a two-year pilot with a consortia formed by EDP and three other major energy player across the world which can lead into a Venture Capital investment; the second pilot project to highlight is a collaboration between EDP Innovation and E-REDES to further develop technologies for voltage control together with three start-ups – Elexys, Idenergie and IONATE - that will support grid improvement and reliability. Ventures 2022 was a remarkable year for EDP Ventures: • record year in terms of investment: ~14M€ of venture capital investments (compared to ~5M€ of average annual investment in 2018-21) • seven new portfolio companies added to the portfolio, across different domains • first investment in Green H2 domain (Hysilabs, which developed a novel hydrogen carrier technology able to transport and store H2 in a liquid state) • first investment in Singapore (Green Li-ion, which developed a technology to rejuvenate li-ion batteries) • significant rounds raised by portfolio companies, namely Sepio Systems, Probely or Yotta Energy • EDP Ventures has sourced +550 start-ups • sponsorship of Ecosummit and Energy Tech Summit event, giving additional visibility to EDP Ventures within the VC climatech ecosystem. Current portfolio is composed by 38 companies across all the innovation domains from several geographies, from USA to Australia and offers high valuation and exit perspectives which result from solid pipeline and high internal and external sourcing efforts. During 2022, there were several collaboration projects between companies in EDP Ventures portfolio and EDP business units, in several geographies, contributing to innovation within the group; currently, +90M€ of total contract value was closed between portfolio companies and 

Integrated Annual Report 2022 Performance Sustainability 117 EDP group. Several opportunities with relevant tickets are in negotiation and expected to close during 2023. Innovation enablement and expertise Last year market a significant dissemination of the innovation culture across the organization: EDPI initiatives reached 830 internal audience FTEs (with 15% participating in more than one initiative) and a further 1,482 colleagues from 29 corporate areas and 22 different countries via our online Innovation Global Community. Below are some of the highlights: • the Innovation Immersion Program in Tel Aviv immersed 15 colleagues from 12 Business areas and three Geographies. In 1Q 2023, to the program will take and extended delegation to visit Singapore´s innovation ecosystem • the Innovation Global Community, with its+700 subscribers from 15 countries and 22 Business areas hosted 16 live sessions and five workshops with over 1 500 participants since its launch in February 2022 • once again, EDP returned to the Web Summit conference with a delegation of 185 EDP colleagues from four countries and 15 business areas, and Executive Board speaking opportunities on the Planet Tech and Corporate Innovation stages. During the four days EDP registered 1,230 participants’ engagements on the EDP stand and in parallel over 600 meetings were held with prominent stakeholders that led to +200 qualified Innovation leads • ground breakers brought together 82 colleagues, from 12 business areas, ten nationalities and the five Innovation hubs at EDP, the first in person meeting of the Innovation Global Team. In parallel, EDPI was also particularly active this year in the development of expertise on the Energy Transition, bringing significant value added to the Business Units and for top management decisions. Final remarks Overall, 2022 was very important consolidation year, which reinforced the importance of the innovation at EDP, and of EDPI in catalysing EDP’s businesses and providing optionality for potential future businesses for the group. 3.6.2.3.2. Research and development EDP NEW – Centre for NEW Energy Technologies is EDP’s Research and Development Centre, fully dedicated to the development and implementation of innovative / R&D projects across different areas of the energy sector. NEW adopts a collaborative approach to innovation, partnering with EDP’s business units and multiple European institutions, companies and universities to develop large R&D projects leveraged by public competitive funding for Research and Innovation – like the European Commission’s Horizon 2020 and Horizon Europe programs. EDP NEW’s current project portfolio includes nearly 40 ongoing projects covering all the 7 (+1) innovation domains in EDP’s innovation model. These projects focus on developing, testing, validating and scaling- up innovative concepts, technologies and business models that contribute to EDP’s objectives and to the global decarbonization targets. Organized around five technical areas closely matching the innovation domains, NEW currently boasts over 50 researchers with distinctive and increasingly diverse academic backgrounds and profiles and complimentary skillsets. Since its establishment in 2015, NEW has secured close to €30 million in funding for R&D and innovation for EDP, which have supported NEW’s growing and sustainable operation based on an agile, project-based structure complimented by international technical consultancy and partnerships. NEW is also continuously scouting for emerging solutions and technologies in the energy sector and beyond, crucially supported by its wide network of 700+ top tier partners across Europe, to continue to create knowledge and help shape the energy future through applied R&D. 

Integrated Annual Report 2022 Performance Sustainability 118 Case studies: key projects at EDP NEW EU-SysFlex EDP was one of the leading partners in the recently concluded R&D project EU-SysFlex. This project aimed to contribute to the acceleration and massification of deployment of renewable energy. For four years, the project’s 34-partner consortium developed and tested several flexibility tools to help ensure a stable, safe and reliable integration of large shares of variable renewables in the European power system. Pilots of the various solutions created were carried out in 6 different European countries, including Portugal, with EDP taking the lead of the demonstrations of two concepts. One was a utility-scale Virtual Power Plant (VPP), for the joint operation and management of variable (Wind) and controllable renewables units (Hydro). The successful tests in operating EDP’s assets established the VPP as a powerful generation portfolio management tool which may prove an alternative option to enable the participation of variable RES in energy markets. The other concept, the Flexibility Hub, is a new market platform to source and integrate flexibility from the various players in the power system – consumers, grid assets – and then use this flexibility to ensure grid stability and reliability. POCITYF The POCITYF project is coordinated by EDP and is aimed at creating positive energy blocks – zones of a city with an annual positive energy balance: locally-produced renewables energy superior to the energy demand. The project covers the heritage cities of Évora, Portugal and Alkmaar, Netherlands, as well as six more fellow cities spread across Europe. Through the implementation of these positive energy blocks, POCITYF aims to transform the urban fabric of these cities, with relevant cultural and historical areas, more affordable, healthy, accessible and reliable for is citizens. In Évora, building integrated PV innovative solutions, such as shingles and glass, will be installed respecting the architectonic and cultural heritage of the city. Additionally, a Community Solar Farm will be built, and second life residential batteries will be used, together with a P2P energy trading platform and control algorithms to provide flexibility and market services.

People management Alignment with the SDGs Objectives KPIs 2022 Target 2025 Employee Engagement 84% High performance company Female employees 27.5% 30% 3.6.2.4.1. Our purpose EDP is committed to evolving as a global, agile and efficient organisation, with a people- centred approach that seeks to attract, develop and retain the skills needed to meet the challenges of the future. In order for EDP to be a truly future-proof organisation, an ambitious People and Organisation (P&O) strategy has been defined, with the intention of fulfilling the following in the coming years: • provide its people with a human and meaningful experience, through global purpose and skills, and concrete measures of wellbeing and flexibility • focus on attracting and retaining internal talent, through a strong global strategy of employer branding and onboarding, as well as a customised career and development strategy • foster growth opportunities for all employees in an engaging manner, in line with a global development mindset • invest in collaboration and promotion of mobilities as a way of sharing knowledge, and individual and organisational development • treat diversity, equality and inclusion as catalysts for innovation • promote agility and efficiency through the improvement and digitalisation of processes in order to reduce decision-making time • use the global tools of people analytics as instruments to support decision-making and strategic planning. The major events of 2022, which continue to transform the global labour market, reinforce the importance of today for the changes of tomorrow and of preparing EDP for the challenges of the future whilst at the same time meeting the needs of its people, which has grown significantly compared to 2021: • increase of 7.4% in the global population (906), considering the inclusion of six new markets and 19 new headcount companies, representing 17 new nationalities • increase of 1.6% in voluntary turnover (5.7%) • increase of 0.8% in the global representation of women (27.5%) and of 1.9% in leadership positions (28.4%) • generations Y and Z already represent around 61% of the global population, with an increase of 5.5% of generation Y in leadership positions (42%) • growth of 1.4% of people working outside their country of origin (3.6%), in a reality where 60% of the global population continue to work in a hybrid model. Considering the current size of the EDP group, the work developed in terms of people management in 2022 was based on the activation of a new people narrative through the integration of a global purpose, supported by 12 human skills, in the main people management processes, strengthening the sense of belonging and pride in employees: Our energy and heart drive a better tomorrow 3.6.2.4.2. Our energy Is the strength, legacy and motivation of EDP's people to deliver green energy continually, leading to an increasingly empowered organisation. Organisation EDP seeks to promote the sharing of best organisational practices and ensure the delegation of skills and digital tools suitable for the fulfilment of its objectives. In 2022, the transition to a management model by business platforms continued, with the unification of the Generation platform (Portugal and Spain) and the implementation of the Client Solutions, Networks, Shared Services and Energy Management platforms. In addition, platform KPIs were added to the organisational performance management model and global guidelines were approved for a greater Span of Control, a decrease in the number of 

Integrated Annual Report 2022 Performance Sustainability 120 management levels (from seven to five) and a general reduction in the weight of Enablement Functions. Efficiency and decision-making In 2022, the efficiency of the P&O and decision-making systems was also assured, with the implementation of various improvements that allowed a reduction of more than 1,300 hours of work and the introduction of five new attributes in the About Me platform, allowing greater refinement of people data. To continue improving the efficiency of its processes, a three-year digital roadmap was also followed up in 2022, with the aim of improving digital maturity, governance model and P&O reference architecture. Cooperation EDP has also been discovering new opportunities to bring its people together, through digital collaborative tools such as virtual global communities. Currently, EDP has already implemented eight global communities (Finance Ahead; ESG; People & Organization; Global Energy Management; Brand & Communication; Innovation; Digital; Generation), connecting more than 30% of the global population and providing access to content and initiatives in an innovative and customised way to each functional family. 3.6.2.4.3. Our heart People are at the heart of EDP's strategy, and this dimension of its global purpose reflects their importance and fundamental role in delivering the organisation's commitments to customers, partners and communities. Recent years have led the EDP group to rethink its working models in favour of a more flexible and balanced working environment and to an active listening strategy that has demonstrated the organisation's work in this direction. Organisational climate The organisational climate constitutes a fundamental, active-listening tool for monitoring different dimensions of employee experience, and the 2022 climate survey had the participation of 93% of EDP group employees. In terms of engagement, it was found that 84% of employees feel involved with the company, where the majority show pride in working for EDP (89%) and would recommend EDP as a great place to work (80%). In terms of empowerment, it was also concluded that 72% of employees have a high perception of organisational support, where 79% feel they have the opportunity to carry out challenging work and 75% believe that their skills and abilities are well used. Rewards and benefits The work environment at EDP must also create global conditions of equality and recognition. Therefore, in 2022, and through the global compensation strategy defined in the previous year, it was possible to standardise compensation concepts in all EDP markets and define a global compensation strategy, encompassing annual base salary, short and long-term incentives, customised competitive benefits and guidelines for total remuneration of merit programmes. Furthermore, the organisational segments associated with a set of job grades were reviewed and a new functional family model was defined, fostering branching career paths. EDP globally assigns long-term incentive plans to the Top Management segment and critical positions in the Senior Management segment. The Executive Board of Directors (EBD) considers the attribution of these incentives as a tool for attracting and retaining talent, focusing on achieving results, and complying with the business plan. Flexibility and welfare In 2022, in addition to consolidating its hybrid working model, EDP extended Flex Fridays to all its markets, a voluntary measure to make working hours more flexible, allowing employees to adapt their weekly working hours and not work on Friday afternoons. Throughout 2022, continuity was also given to the global strategy of well-being defined in the previous year, based on five pillars (physical, social, professional, financial and emotional). To this end, global awareness campaigns have been developed (e.g.: Global Well-being Week; Mind Your Mind) to encourage the adoption of healthy behaviours, the accountability of the organisation's leaders was promoted and the global offer was revised and simplified for better communication and access to the different channels and helplines. 

Integrated Annual Report 2022 Performance Sustainability 121 In recent years, EDP has promoted the Mind your Mind campaign in order to raise awareness of the importance of mental health. As part of its global well-being strategy, this campaign calls for preventive behaviours and publicises the various assistance and support services available, through different types of initiatives (eg., talks, workshops, testimonials). Gabriela Pesente, an EDP Brasil employee, shared her personal experience through one of the initiatives of this campaign, the "Trust Space". “Here at EDP, I have always been lucky to have managers I could talk to, but I have also had other people I could always talk to, such as in the health area, always available, work colleagues. So, I think that as a company, we have to be aware of how significant we are in the life of the individual and keep the doors open to give a person access. When I make myself vulnerable before another person, they know they can count on me.” Gabriela Pesente, Planning Consultant, EDP Brasil To access the full interview, click here. In 2021, EDP Brazil launched the first electrician school exclusively for trans people, a pioneering initiative in the electricity sector. There were two classes, both formed in June 2022, and of those 19 people, 73% are now members of staff at EDP or its partners. “I´ve been working with the transgender population since 1990, and I can count on the fingers of one hand the number of truly revolutionary projects that actually changed the lived experience of this truly excluded and forgotten group. Without a doubt, the formation of this school is one of those moments. A project that goes beyond employability and thinks about equity and real inclusion, that builds bridges across such a giant abyss of multiple inequalities. I am proud to be part of this beautiful seed that will now not stop producing good fruit.” Maite Schneider, TRANSEMPREGOS Cofounder Maite Schneider Gabriela Pesente 

Integrated Annual Report 2022 Performance Sustainability 122 Diversity, equality, inclusion and sense of belonging By ensuring fairness and inclusion for its people, EDP is also creating a more diverse working environment. To reflect the EDP group's maturity in these matters, the acronym DEIB (Diversity, Equity, Inclusion and Belonging) was adopted in 2022 and included in the revision of the Global Policy, which determines a set of responsibilities and mechanisms to promote a more human and innovative company. In addition to various awareness-raising initiatives and continued efforts to promote increasingly inclusive recruitment, the first Global DEIB Council was held in 2022, which set out the priorities for the next business cycle, and the Gender Equality Plan (2022-2023) and Equal Pay project were reviewed, ensuring internal cross-cutting practices to guarantee pay parity. 3.6.2.4.4. Our impetus This dimension of EDP's global purpose reflects its ambition of, and leadership in, bringing about change as an organisation prepared for the challenges of the future. Talent attraction For EDP, it is essential to develop a strong employer branding strategy that is increasingly global and attractive, which, in 2022, meant revising its employee value proposition to reflect the company's global positioning and its flexible, inclusive and development-oriented culture. Overall, in 2022, the EDP group impacted more than 55,000 people, through more than 190 initiatives and strong positioning on its main social networks, which resulted in more than 500 people-related content. In addition to this digital communication, EDP used other digital tools to strengthen its relationship with candidates - for example, a monthly newsletter with 6 issues and around 80 mail shots. In 2022, the attractiveness strategy gave rise to more than 235,000 applications in EDP's different markets, resulting in 1,797 admissions and 647 internships, mostly with fully digital recruitment processes. In 2022, the first global Onboarding experience was also designed and the EDP group's Mobility Policy revised, processes that play a fundamental role in attracting and retaining employees. These efforts resulted in several distinctions, such as a new recognition by the Top Employers Institute, highlighting the EDP group's strong positioning with candidates and employees, and its dedication and commitment. Talent development and management 2022 was a turning point, with the implementation of a global development model based on a holistic assessment of the employee, considering his/her past individual performance, his/her skills in the present and his/her capacity to face future challenges. This mindset is supported by regular development conversations and a new learning and development experience, which enables access to a myriad of on-demand content. The change management process for this mindset involved over 300 sessions and over 9,000 employees. Throughout 2022, a new development approach was also established for EDP's leadership, characterised by a focus on prioritising topics related to the areas of leadership, digital, innovation, safety, ethics and compliance. By 2022, total EDP group training was more than 200 thousand training hours. The EDP group's employee succession plan is also crucial to ensure the continuity of the business, acting as an important people management tool. In 2022, objective criteria were defined to continue to build a global and diverse leadership pool, with the succession exercise involving the positions of the Top and Senior Management segments. As a result of this exercise, 173 successors and 355 potential career moves for 71 Top Management positions and 620 successors and 1,125 potential career moves for 290 Senior Management positions were mapped. Considering EDP’s growth, the competitiveness of the market and the scarcity of talent, several customised development initiatives for these segments and their successors were also ensured in 2022. 3.6.2.4.5. A better tomorrow EDP's current strategy sets out ambitious commitments for the coming years, allowing it to become a future-proof organisation focused on providing a better tomorrow for current and future generations. 

Integrated Annual Report 2022 Performance Sustainability 123 In this sense, EDP's P&O strategy will continue to focus on meeting the challenges of attracting, developing and retaining the skills needed to meet the challenges of the future, ensuring: • a global organisational design strategy that supports management by platforms • a strong employer branding strategy to attract the best talent • greater digital maturity and efficiency of processes • greater collaboration through the implementation of new global communities • an inclusive and flexible working environment that promotes well-being • a culture geared towards learning and development that holds employees and leadership accountable. With people at the centre of its strategy, EDP will thus continue to work towards an increasingly human and meaningful experience for all its employees, guaranteeing that what we do today makes a difference tomorrow. 

Integrated Annual Report 2022 Performance Sustainability 124 3.6.2.5. Health and safety Alignment with the SDGs Objectives KPIs 2022 Target 2025 Severity index (employees and contractors) 118 <150 Fatal accidents (employees and contractors) 5 0 EDP uses Humanisation as one of its fundamental values and places people at the heart of its strategic agenda. Safeguarding the health and safety of employees (both inside and outside the group), suppliers, external service providers (ESP), customers and stakeholders, is an EDP group priority. For the group, no situation or emergency can justify endangering a person's life! In fact, EDP guides its action in this matter by the principles established in the Health and Safety at Work Policy, a binding document that covers all group employees and external service providers, making the entire hierarchical structure responsible. To this end, the EDP group requires everyone to adopt practices in line with the principles of this policy, in order to ensure continuous improvement. Safety practices The implementation of EDP's annual occupational health and safety programme was based on a set of actions aimed at preventing occupational accidents, as measured by a reduction in the frequency rates and the seriousness of accidents and occupational illnesses, and included training for EDP employees and service providers, the ongoing evaluation and control of labour risks and the implementation of an internal and external inspection and audit programme of EDP facilities and works. The Plan of Strategic OHS Objectives contains the repository of commitments and initiatives undertaken by the different organisational units for the execution of the six vectors of intervention defined on a strategic and corporate level, concerning OHS approved for 2020/25: (1) Commitment of leaderships to OHS; (2) Behaviour, preventive activities and learning from mistakes; (3) Streamlining, digitalising and standardising OHS processes in the EDP group; (4) Skills; (5) Communication and involvement; (6) Management of OHS in the contracting of SHP. With regard to emergency preparedness and response, 460 simulated drills were carried out throughout the EDP group, covering various industrial, administrative and construction sites, in order to test the effectiveness of the planned response capacity in potential emergency situations. These drills included the participation of the civil defence force, the fire brigade, police and public safety authorities, as well as employees, service providers and the surrounding communities. In order to prevent electrical accidents involving third parties not involved in the group's activity, EDP ensures that the risks associated with its facilities and equipment are identified and communicated. However, in 2022 there were 41 accidents of electrical origin with third parties, which resulted in the deaths of 14 people. These accidents were the result of civil construction activities, tampering with the grid and leisure, among others. Safety indicators The Health and Safety at Work Policy within the EDP group demonstrates its commitment to a model of Health and Safety Work Management based on continuous improvement and the conviction that working in a safe, healthy environment is instrumental for employee satisfaction and provides added value for successful results. To improve management of the Policy objectives, EDP has a Corporate Safety Management System based on ISO 45001:2018 and the ILO-OSH 2021 recommendation. This system can be adopted in its entirety by each of the companies, or, alternatively, taken as a reference for the implementation of their own systems. In 2022, the EDP group counted a total of 10,604 employees covered by ISO 45001:2018 certification. The certification covers 96% of net installed power in production activities.

Integrated Annual Report 2022 Performance Sustainability 125 In EDP group, 133 work-related accidents occurred out of all EDP employees and service providers (ESP), representing a reduction of 13% compared with 2021. The frequency rate (FR) amongst EDP employees and service providers in 2022 grew 3% compared with the previous year, consequently we were unable to achieve the target of 1.69 set for 2022. During 2022, there were six fatal accidents at work with service providers (fall from height, electrical origin) and one accident in commuting (road). Additional information visit www.edp.com. FREQUENCY RATE (Fr) SEVERITY RATE (Sr) Accidents that occurred due to interaction with objects are responsible for 33% of accidents, followed by incorrect movements or over-straining at 14%, 11% being falls from heights, 8% of electrical origin, and 20% attributed to other causes. TIPOLOGY OF ACCIDENTS AT WORK (%) Health promotion The health and well-being of the group's employees are promoted and protected through compliance with occupational health monitoring requirements, in accordance with applicable legislation. Health monitoring programmes guarantee fulfilment of the regular medical examinations plan, workplace inspections, participation in the Occupational Health and Safety and Internal Accident Prevention Committees, and the implementation of a range of preventive campaigns. During 2022, 10,311 medical exams, 1,175 consultations with employees who have nutrition programmes, 1,105 cardiovascular screenings and 3,776 vaccination programmes against influenza, pneumococcal infection, hepatitis B and yellow fever, which covered 1,212 employees, were carried out in the EDP group. Also, within the scope of occupational medicine activities, 11 screening sessions for alcohol and drugs were carried out. EDP group monitors and follows up the occurrence of occupational diseases.

Integrated Annual Report 2022 Performance Sustainability 126 3.6.2.6. Crisis management Alignment with the SDGs Objectives KPIs 2022 Target 2025 BitSight rating 810 ≥740 Climate change adaptation plans implemented 50% 100% Organizations today face a multiplicity of adverse situations, as a result of their international positioning, making them more exposed to the materialization of disruptive events with high negative potential. Being aware of this position allows, on the other hand, to adopt a state of continuous monitoring and alertness, for the evolution of possible crises on a global scale with impact on the organization. The EDP group assumes Crisis Management as a strategic capacity that enhances its supported and sustainable response to abnormal situations, characterized by high uncertainty and with potential negative impact on its strategic and business commitments and objectives, requiring urgent attention and action to protect the life and physical integrity of people, the environment, the assets, and reputation of the EDP group. The EDP group Crisis Management Plan (OS 4/2021/CAE), which is transversal and strategic in nature and aligned with the reference BS 11200:2014, establishes the management structures, guiding principles for decision making and practices to be observed in the three phases of the crisis management process: before, during and after the crisis. Alongside the Crisis Management Plan, the Crisis Communication Plan was established, which supports the actions of the teams responsible for ensuring effective communication - transparent, coherent, and consistent - in these highly complex and volatile contexts. Designed to allow a strategic response to crisis and pre-crisis situations of a diverse nature and with different levels of complexity, these plans are reflected in the Business Units and Divisions of the Corporate Centre, when applicable, ensuring the tactical and operational capacity to respond to the Crisis, and an adequate escalation to the EBD and the EDP group's Crisis Management Office. In order to strengthen its resilience, the EDP group established, in the OS 1/2018/CAE, its approach to Business Continuity Management, also specifying the methodological parts to be observed, in alignment with the ISO 22301:2019 benchmark, strengthening its ability to detect and respond appropriately to risks with potential impact on its activity. EDP has therefore developed and has a robust set of human, procedural and technological controls, and safeguard measures that it has been improving, complemented by recovery plans at the operational level, such as the Business Continuity Plans for priority processes/services, Contingency Plans or Disaster Recovery Plans, among others. These allow EDP to increase its capacity to continue to provide its services at acceptable levels even in the face of incidents, emergencies, and disasters, fulfilling the assumed objectives. To ensure their effectiveness and adequacy, the plans are subject to periodic exercises and simulations, both internally and in collaboration with external entities relevant to EDP's value chain. Also noteworthy is the creation of the Safety, Security & Business Continuity Unit (SSBC) in January 2022, which allowed the strategic reframing of the themes of Crisis Management and Business Continuity, Safety (prevention and security) and Security (physical security and duty of care), with a view to the holistic and transversal management to the group of a set of related themes and whose complementarity and integrated approach adds benefits to EDP. With a view to strengthening this commitment, the EDP group has defined the Security Policy (OS 8/2022/CAE), which establishes the guiding principles to be followed by all Business Units and Corporate Centre departments. Monitoring the evolution of the Russia-Ukraine conflict In February 2022, following what was established in its Crisis Management Plan and Crisis Communication Plan, EDP assumed to be facing a Pre-Crisis Situation, motivated by the emergence of the Russia-Ukraine conflict, which resulted in a worsening of geopolitical instability in Europe and worldwide. Starting an intensive follow-up of the evolution of this situation, a monitoring group was established that includes different areas of the Corporate Centre of EDP, S.A., and the Business Units, especially those with a greater presence in the region. This monitoring is carried out in terms of topics such as the physical safety of people and assets, cybersecurity, 

Integrated Annual Report 2022 Performance Sustainability 127 business continuity, risk management, supply chain, energy management, finance, regulation and stakeholders, compliance, communication, and social support. This monitoring group, under the coordination of the SSBC, meets regularly and is responsible for reporting to the EBD on the main risks existing at each moment, changes in the environment, the status of implementation of risk management measures defined, as well as measures proposed for adoption. The presence of EDP Renováveis and, more recently, EDP Comercial in countries bordering the conflict zone led to the adoption of a series of immediate measures to safeguard its people in these regions and the EDP group's people from Ukraine and Russia who are in other operations, as well as its assets under construction and in operation, including Evacuation Plans. As a complement to the analysis and monitoring of the situation by the different areas of EDP, it also opted to use entities specialized in the management of geopolitical conflicts, in order to acquire greater knowledge of potential developments and thus anticipate its response to potential risks or threats. Considering the possible scenarios of the evolution of the conflict, an evaluation was developed of the most relevant risks and impacts for EDP, and of the main risk management and impact mitigation measures. 3.6.2.6.1. Information security EDP recognises information security as a strategic objective and a fundamental business requirement, and makes this commitment at top management level. The EDP group's Information Security Policy, approved by the Executive Board of Directors, establishes information security as a competitive factor, generating confidence in its stakeholders, but also as a critical responsibility in a social context, as a result of its role as an operator of critical infrastructures and manager of large volumes of personal data on customers and employees. The governance of information security in the EDP group involves the existence of the Digital and Information Technology Committee. This committee includes members of the various business units´ management, the Company´s Chief Information Security Officer (CISO) and a member of the Executive Board of Directors, who chairs it. This committee has, among others, the task of discussing and issuing opinions on guidelines for the strategic planning of information security, and is also responsible for assessing the company's cyber-security risks, monitoring scenarios of serious incidents in the energy sector and the organization's cyber- security risk profile. Every month, the Executive Board Director responsible for information security receives a report of activities and indicators from the organisation's CISO and the entire Executive Board receives the same information on a quarterly basis. The EDP group's cyber-security risk is presented annually to the members of the General and Supervisory Board. Cybersecurity in 2022 in the EDP group 2022 was marked by changes in cyberspace. From the beginning of the year we saw high- impact cyber-attacks on organisations from various sectors, such as media, communications service providers and retail in Portugal, but also attacks on European port terminals and other infrastructures supporting essential services around the world. Some of the attacks were only destructive with unknown motive, which, along with the conflict in Ukraine, confirmed the trend of joint and coordinated action between physical and cyber conflict ("Hybrid Warfare"), aggravating the risk of cyber threats, particularly in the energy sector, which became one of the main targets of attack. In order to face the new cyber threats, EDP raised, in the first quarter of 2022, the cyber risk alert level to orange throughout the group, which resulted in an increase of 24/7 monitoring, at the same time as it integrated more information sources in its security operations, having also promoted additional business continuity exercises, specifically an exercise called "Red Button" that simulates a service disruption that forces the isolation of critical networks and systems. Although there was an increase in cyber threats throughout the year, apart from a few DoS (Denial of Service) attacks on the corporate edp.com and edp.pt websites in July and September, which resulted in temporary difficulties accessing these resources, no incidents with a significant impact on either the group's image or its operations were recorded throughout the group. Cybersecurity activities and indicators The rating adopted, defined as the group's KPI for this area, observes the EDP group's behaviour in cyberspace, specifically by checking aspects such as the security of its public websites, access from its networks to dangerous locations and incidents that affect the organisation publicly. During 2022, the rating remained at the advanced level, oscillating between 790 and 810 points, well above the average for the sector. 

Integrated Annual Report 2022 Performance Sustainability 128 To support the challenge of energy and digital transitions, as well as efficient and secure operations in EDP's energy networks and facilities, a "Zero Trust" strategy for cybersecurity was adopted, comprising a plan of initiatives for the years 21-23, both in the domain of networks and IT systems and in the OT domain (Operational Technology that supervises and controls energy management infrastructures, some of which are mission critical). Plans are being executed without major deviations from the original. With regard to awareness and training, because of the pandemic, which made face-to-face training impossible, the training schedule in EDP's “cyber range” (a unique cyber security training infrastructure in Portugal, which simulates, in the classroom and with real equipment, the power grid’s control systems), and was also adapted to remote format. However, due to the easing of restrictions in the face of the pandemic, we had about 30 in-person trainees in 2022\. There is also integrated programme of training, e-Learning and security exercises for delivery across the entire EDP group, which was delivered to 11,000 employees in 2022. In addition to its operational capabilities, the EDP group's vision is to position itself as a company of reference in the use of best practice and innovation in the area of information security. In this sense, the EDP group continues to integrate several national and international work and study groups (such as CERT.PT, the World Economic Forum, the Cyber DSO group \- Distribution System Operators - and the International Energy Agency), as well as European projects with other European counterparts, academic and governmental organisations. BITSIGHT SECURITY RATING 3.6.2.6.2. Critical infrastructures Directive 2008/114/EC defines "Critical Infrastructure" as "the asset, system or part thereof located in Member States which is essential for the maintenance of vital societal functions, health, safety, security, economic or social well-being, and the disruption or destruction of which would have a significant impact in a Member State as a result of the failure to maintain those functions". EDP has under its responsibility a set of critical infrastructures in Spain and Portugal, which include electricity generation and distribution infrastructures (physical and control facilities), as well as related customer service activities, which have been identified within the scope of the transposition of Directive 2008/114/EC into Spanish and Portuguese law. It should be noted that a new European directive was recently approved, Directive (EU) 2022/2557 of the European Parliament and Council of December 14, 2022, on the resilience of critical entities (repealing Directive 2008/114/EC with effect from October 18, 2024), which is awaiting transposition into national law. Due to the diversity of the critical infrastructures under its responsibility, EDP has proactively adopted strategies to respond to risks of different natures, such as physical risks (e.g., fires, earthquakes, atmospheric events, including extreme events), and technological risks (including, but not limited to, cybersecurity risks for operational systems and information systems). In addition, the measures and tools adopted to mitigate these risks are diversified and different in nature, adjusted to the specifics of the infrastructures, necessarily covering physical security (safety and security aspects), technological security and cybersecurity, as well as the management of Business Continuity, leveraged by a strong component of training and exercises. EDP has developed, for each of the critical infrastructures, the respective security plan, supported by the conclusions of the risk analysis on them and the set of measures implemented, in line with the provisions of Directive 2008/114/EC and in alignment with the recently revised national legislation DL 20/2022 (repealed DL 62/2011). Furthermore, it is important to mention the role assumed by EDP in promoting the adoption of good practices in the management of critical infrastructures in the sector, through its dissemination, but also through collaboration with external entities, participating in exercises and workshops relevant to the topic. 800 805 810 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 

Integrated Annual Report 2022 Performance Sustainability 129 With a focus on establishing and developing a Security Culture, EDP promoted a set of awareness-raising activities, provided by SIS - Security Information Service; (i) the Knowledge and Sensitive Information Protection Program, which aims to alert entities in Portugal to espionage threats and raise their awareness of the importance of protecting knowledge and sensitive information and (ii) the Krítica Program, with the aim of contributing to improving the protection of critical infrastructures and sensitive national points against the terrorist threat. Also, in this context and following the approval of the Sendai Framework for Disaster Risk Reduction 2015-2030, EDP has participated, in Portugal, in the National Platform for Disaster Risk Reduction (PNRRC in its Portuguese acronym), under the responsibility of a sub- committee coordinated by ANEPC (National Authority for Emergency and Civil Protection). We highlight the participation in the development of the Handbook on "Good Resilience Practices for Critical Infrastructure - Private Sector and State Business Sector", as part of the PNRRC activities for the 2015-2017 triennium, available on the PNRRC website. 3.6.2.6.3. Infectious diseases Preparation for crisis situations, particularly focusing on people's health and protection is part of EDP's performance and commitment. The EDP group Contingency Plan was created during the course of infectious disease situations and in order to prepare the company for similar or more serious future situations, such as pandemics. This track record for continuous monitoring of epidemiological situations through the implementation of Contingency Plans allowed EDP to be more prepared when, in 2020, the COVID-19 Pandemic was decreed. The Contingency Plans define EDP's procedures for the adequate management of the impacts around these situations, which may affect employees and service providers, as well as the group's companies´ business, which includes: • safeguarding people's lives in order to reduce the risk of contamination in the workplace, strengthening the information and knowledge of the employees and favouring self- protection • implementation of a decision-making and coordination structure in EDP and the group's companies • activation of the Business Continuity Plans, in order to guarantee an adequate operational response capacity that simultaneously minimises the conditions for the propagation of the pandemic and ensures the functioning of essential services • monitoring the progress of the disease, the effectiveness of the measures taken and the need for further action depending on the context within and outside EDP • responding to internal and external notification and communication needs • resumption of activity under safe conditions as soon as the country/region allows. Given the pandemic data, the governments of the countries where EDP operates have established a plan for the gradual lifting of restrictive measures. The evolution of vaccination against Covid-19 allowed for a move towards the relief of restrictions through a gradual and extended plan. EDP accompanied this plan and, in accordance with the directives, went ahead with a survey of the measures applied in all the countries in which it operates.

Creation of a long-term value We address the path of sustainability by facilitating the long-term investment in companies. This means to channel the capital into sustainable assets. Since 2004, EDP has announced publicly the commitment to carry on its business while seeking a balance between the economic, environmental, and social aspects of the company’s activity and pursuing an approach that incorporates the priorities of their stakeholders. In 2022, the economic value generated by EDP was 22,661 million euros, compared to 16,480 million euros in 2021. This value includes turnover and other income. In 2022, 90% of the Generated Economic Value (GEV) was distributed in a total amount of 20,375 million euros. The aggregated economic value (AEV), the difference between the GEV and the Distributed Economic Value (DEV) corresponds to the remaining 10% and includes retained earnings and non-payable costs. ECONOMIC VALUE GENERATED (€M) 3.6.3.1.2. EDP ESG performance assessment During 2022, EDP has carried on the efforts of providing ESG data (qualitative and quantitative) to several ESG analysts. Analysts are evaluating the group's performance on climate change, policy commitments, worker safety, diversity, governance and other ESG factors, based on each in-house methodology. This explains why scores, ratings and/or level of risk obtained based on different ESG performance indicators, such as GHG emissions or violations against the UN Global Compact (UNGC) used by the different analysts are not comparable with each other. EDP achieved its objective of inclusion in the upper quartile in performance against the ESG ratings established for 2025, in the Dow Jones Sustainability Index, Sustainalytics, FTSE4Good Index Series, and MSCI ESG Indices. It should also be noted that the group has responded to questionnaires that grant recognition in the areas of climate change and water management (CDP Climate Change and CDP Water Security), in sustainability (GRESB) and in ethics (Ethisphere Institute). 2 449 2 136 2 285 11 307 14 344 20 375 13 756 16 480 22 661 2020 2021 2022 Distributed Economic Value Accumulated Economic Value

Integrated Annual Report 2022 Performance Sustainability 134 3.6.3.1.3. Facts & figures of sustainable finance Since the 2030 Agenda for Sustainable Development and the historic signature of the Paris Agreement, there have been made important progress in the battle against climate change and towards a greener, more resilient, more inclusive global economy. Sustainable finance has the potential redirect the funds to climate action and transition to a climate-neutral economy. According the last report of the Global Sustainable Investment Alliance – GSIA Report 2020) the global sustainable investment reached USD35.3 trillion in five major markets (Europe; United States; Canada; Australia; Japan)-. Sustainable investment assets under management make up a total of 35.9% of total assets under management, up from 33.4% in 2018\. The GSIA expect that sustainable investment could exceed USD 50 trillion by 2025. Investors The year 2022 started with the implementation of the ambitious agreement “Glasgow Financial alliance for Net Zero (GFANZ)” established in November 2021, which assembled a few of the world’s most powerful financial institutions to fight global warming, by pledging to bring loan and investment portfolios to net-zero by 2050. However, as the year unfolded, sustainable finance had to stave off a backlash against ESG policies. At the end of 2022, Vanguard group, the world’s second-largest asset manager and a major index investor, pulled out the GFANZ, saying it aims “provide the clarity our investors desire about the role of index funds and about how we think about material risks, including climate-related risks.” Regulators In July 2022, the European Central Bank (ECB) announced, a measure to be applied from October 2022, that will adjust the purchase of corporate bonds and the pandemic emergency purchase programme according to a climate score based on three factors: backward-looking emissions (issuers’ past emissions), forward-looking targets (issuer’s ambitious decarbonization targets) and climate disclosures (issuers’ reporting of greenhouse gas emissions: scope one, two and three). The EU is following a step-by-step approach starting with the climate taxonomy (2022), the environmental taxonomy (2023) and the social taxonomy (with no date yet known). Other EU regulations are building on the different dimensions of the EU Taxonomy, as for example: • the Corporate Sustainability Reporting Directive (CSRD)- This regulation was published on 16 December 2022 in the Official Journal. It will be applicable in 2025 to companies already subject to the Non-Financial Reporting Directive – NFRD • the Sustainable Finance Disclosure Regulation (SFDR) – This regulation was published on 9 December 2019 in the Official Journal. It has been applicable since 10 March 2021. It is a key regulation to increase transparency and enable investors to reorient capital • the Corporate Sustainability Due Diligence Directive (CSDDD). This regulation proposed, for the first time, a mandatory framework for companies registered or operating within the EU to carry out due diligence throughout their supply chains and to identify, prevent or stop adverse impacts related to human rights and the environment. The final text is expected in May 2023. The last major introductions regarding sustainable finance, in 2022, were the following: • the EU Taxonomy: The European Commission published and adopted the Complementary Climate Delegated Act. This legal text proposes that gas and nuclear activities are classified in the EU Taxonomy framework. Please see EDP’s position in our 2021 Sustainability Report, page 166 • the disclosure under the article 8 of the EU Taxonomy: EDP has disclosed, for the first time in 2021, information on eligibility and alignment with the Taxonomy under the mandatory tables for its revenues, operating expenses (OPEX) and capital expenditure (CAPEX). More details in the Report on implementing article 8 of the EU Taxonomy Regulation • the disclosure of the report on minimum safeguards by the Platform on Sustainable Finance: The purpose is to orient companies on implementing article 18 of the EU Taxonomy • the announcement of new reporting climate disclosures from Securities and Exchange Commission (SEC) and International Sustainability Board (ISSB): Their final goal is to issue the final standards in 2023. 

Integrated Annual Report 2022 Performance Sustainability 135 EDP Impact of ESG performance measurement Currently, 29.8% of the capital of EDP's shareholder structure comes from SRI investors. EDP has demonstrated its expertise in ESG matters and its knowledge to reply to investors who follow active and passive investment approaches. Additionally, regarding the financing component, the group has responded to requests from investors, who are increasingly demanding in terms of mitigating the risks inherent in ESG factors. EDP Sustainability Linked Finance In March 2022, EDP updated its 2018 green bond framework with a new Green Finance Framework. The new framework, which you can found on the following here, is aligned with the Company’s overall sustainability strategy and initiatives and will further contribute to EDP’s key environmental priorities. The framework is aligned with the Green Bond Principles 2021 (GBP), as administered by ICMA, and Green Loan Principles 2021 (GLP), as administered by LMA, APLMA and LSTA. In addition, it is also aligned with the EU taxonomy. The framework is supported by a second-party review from Sustainalytics. The proceeds of the issued green finance instruments are used to finance and/or refinance new and/or existing wind and solar assets of EDP Renováveis (EDPR). Eligible assets include the design, construction, installation and maintenance of wind and solar assets. As of 31 December 2022, our green finance instruments (the first was in 2018) represent 44% of our total nominal debt. EDP has a target to have 50% of its funding from sustainable sources by 2025. Our green bond reporting is done through our annual sustainability report that is audited by an external party. That information appeared on the Report on the allocation and impact of Green Finance. 

Integrated Annual Report 2022 Performance Sustainability 136 3.6.3.2. Caring for our planet Alignment with the SDGs Objectives KPIs 2022 Target 2025 Reducing the intensity of CO2 emissions (scope 1 and 2) -56% -70% Recycling of waste from activities 52% 85% EDP contributes to Sustainable Development, recognising the Environment as a strategic management element and acting towards the prevention of pollution, mitigation of impacts and consequences of its activity. To this end, through its Environmental Policy, the group assumes a set of commitments that safeguard the implementation and maintenance of environmental management systems, certified in accordance with ISO 14001:2015 by accredited external entities. To ensure ongoing improvement, the environmental management of the facilities/activities is aligned with objectives and a strategic plan supported in a Corporate Environmental Management System with the scope "corporate management of policies, commitments and environmental performance of EDP group worldwide". The group's Environmental Policy is considered in the business plan, which leverages and realises the capacity to contribute to the prevention of pollution, resulting in positive evidence in terms of the protection of Biodiversity, decarbonisation, the efficient use of natural resources and the promotion of a Circular Economy. The electricity generation and distribution activities have a significant direct environmental impact in terms of fuel consumption, use of chemical products, greenhouse gas emissions, atmospheric pollutant emissions, water consumption licences, effluent discharge after treatment, effects on fauna, effects on flora and noise in some assets´ specific situations. To ensure the control and mitigation of these impacts, in addition to the existence of Environmental Management Systems certified in accordance with ISO 14001, the thermoelectric power stations are covered by demanding environmental licences, which establish continuous monitoring, taking into account the parameters and sensitivity of the environments in which are located. All thermal power plants have physical/chemical wastewater treatment processes, ensuring that they are disposed of according to the limit values established for each parameter. The reduction in thermoelectric production of coal- fired power stations in the Iberian Peninsula and the early closure plan, integrated into the decarbonisation strategy, result in a significant reduction in atmospheric emissions of sulphur dioxide (SO2), nitrogen oxides (NOx) and particulates. In distribution, the main impact mitigation measures are the landscape integration of overhead lines, oil retention systems and the installation of acoustic barriers. In the management of transformers with polychlorinated biphenyls (PCBs), in addition to complying with current legislation, EDP uses best practice for the identification, screening and appropriate final treatment of PCB waste. The deadline for decommissioning equipment contaminated with PCB concentrations above 50 ppm, defined in legislation and the plans of the relevant companies, is the year 2025. Also worth noting is the fact that in the Brazilian 

Integrated Annual Report 2022 Performance Sustainability 137 distribution companies, all medium and low voltage transformers that are removed from the network are replaced by transformers equipped with vegetable oil. In terms of emergency and incident response capacity in 2022, 99 small oil spills were recorded, containment and remediation measures were taken, also recorded were 101 environmental near-accidents and 270 simulations were carried out. The corrective and prevention measures implemented resulted in zero accidents with environmental damage. In addition, training and awareness-raising events on emergency response are also held for employees, service providers and others involved such as the local community (when applicable). The number of environmental complaints has decreased again in all areas of activity and has reduced globally 15% (vs. 2021). The theme noise represents 23% of the reasons for environmental complaints, followed by the theme waste, with 16% representation. On the other hand, in order to have a positive effect on the environment, EDP continues to invest heavily in improving technologies and in initiatives to prevent and mitigate the environmental impacts of its operations, totalling EUR 105.5 million by 2022. 3.6.3.2.1. Protection of biodiversity Biodiversity is under threat, and it has never been more urgent to restore damaged ecosystems. Expectations lie in strengthening the global commitments and targets of the 2021-2030 agenda, the defining decade recognised as the United Nations Decade for Ecosystem Recovery. According to the United Nations Environment Programme (UNEP), the degradation of marine and terrestrial ecosystems significantly affects the well-being of 3.3 billion people worldwide, and has an associated annual cost of around 10% of the planet's gross product in terms of loss of species and ecosystem services essential for food, agriculture and the supply of quality water, among others. In this sense, EDP assumes the Environment as a strategic management element, aiming to reduce the impacts of its activity through a set of general and specific complementary commitments, expressed by the Environmental Policy, among which is the protection of biodiversity: • contributing to the reduction of biodiversity loss, prioritising mitigation line management and aiming for a positive outcome on the biodiversity balance sheet in the long term • contributing to the deepening of scientific knowledge of biodiversity and ecosystem services, including through the establishment of partnerships. In parallel, EDP also commits to "not building new electricity production facilities in areas that are part of Natural Sites on the UNESCO World Heritage List", to ensure that it continues to have no presence in these territories, and made a global commitment in 2022 to become positive for nature by 2025, which means going further and anticipating the "No Net Loss" commitment already made for 2030, and achieving a Net Gain of biodiversity in all new projects with significant residual impacts by 2025. The location of own assets, leased, administered within or adjacent to protected areas and areas of high biodiversity value outside protected areas are shared openly, in the UN´s own annual reports (EDP Brasil and EDP Renováveis) and in the annual reports, corporate website, and biodiversity reports. In strengthening the biodiversity conservation objectives of the "Net Gain of Biodiversity” project, EDP makes two additional commitments in the baseline mitigation line-management approach, also by 2025: • No Net Deforestation • 100% of its assets with Biodiversity Action Plans (BAPs) defined and implemented, when these facilities are recognised as having high biodiversity risks. At project management level, mitigation line management (see Biodiversity Report 2020- 2022), allows EDP to anticipate and avoid potential impacts; minimise, when it is not possible to avoid them entirely; restore, when impacts occur; and offset, when residual impacts remain. It is a gradual and cumulative process with the main objective of progressively reducing impact until there are no adverse effects on biodiversity and achieving the Net Gain biodiversity conservation objectives. In 2022, in an action underlying the line management of mitigation, EDP developed the Space4Nature (making space for nature) initiative, an initiative promoting Nature-based Solutions (NbS) as a simultaneous response to business and societal problems and challenges. This is a kick-start to the ambition of a positive business for nature (see Biodiversity Report). Also in a commitment to positive business for nature, EDP follows the evolution of metrics and indicators based on science that are being worked on internationally and which are expected 

Integrated Annual Report 2022 Performance Sustainability 138 to stabilise from the second half of 2023 onwards (TNFD, SBTN, GRI, for example) to integrate the biodiversity and natural capital theme in: • identification and assessment of impacts and dependencies, extending to key supply chains. However, in the matter of suppliers and subcontractors, EDP's procurement policy, whenever possible, is already considered a reference to the implementation of policies consistent with those established by society, in particular in the environmental and biodiversity dimension • monitoring the evolution of related risks in different time horizons and integrating this information in strategic and operational planning where applicable. EDP's power generation (hydroelectric, thermoelectric, wind and solar) and electricity transmission and distribution activities have the greatest impact on biodiversity, through disturbances caused by the alteration/conversion of land use that result in the fragmentation, alteration and destruction of habitats with a direct or indirect impact on species However, habitats and potentially-impacted species are the target of the conservation measures and impact mitigation described in three aspects: protection of bird fauna, ecological flows and natural capital. In 2022 the following stand out: Bird protection Portugal In 2022, the Avifauna IX protocol began and actions continued to be developed under the Avifauna VIII Protocol, the LIFE Projects and the National Specific Program for Wild Birds (PENAS). The actions provided for in the Protocol continued the work of surveying the land around certain power lines, and the compilation and validation of information on risk charts of endangered species. The corrections of medium and high voltage overhead power lines (MT/AT) were performed with the use of mitigating technical solutions, such as the rotating “firefly” type to minimise collision, and the change from horizontal to vertical disconnectors and a combined solution to electrocution, at around 15 km. From the beginning of the avifauna protocols (2003) to the end of 2022, there have been about 1,371.7 km (accumulated value) of exist- ing electricity distribution lines corrected with measures to protect avifauna, inside and outside Classified Areas, both in the licensing of electric lines and in the context of voluntary correction. Spain Environmental impact studies have been carried out for EDP Spain network installation projects which, due to their delineation throughout the protected areas, are subject to an environmental assessment by the competent body. Studies that ensure the identification of technical solutions with the lowest environmental impact, and compliance with the minimisation measures contained in the corresponding environmental impact statements (DIA), allow the avoidance of liquid damage to biodiversity. Ecological flows Portugal Of the 16 hydroelectric uses identified for the construction of ecological flow schemes (CERs), 15 have already had their CERs implemented, and their monitoring programmes are underway to assess effectiveness as defined in the Concession Contracts. Only in the case of the Upper Cávado, given the poor quality of the water in the reservoir water and the good quality of the water present in the downstream section of the reservoir, it was decided not to launch an Ecological Flow (EC) given the possible negative effects on the body of water. However, this section of the river downstream of the dam is being monitored. Spain Compliance with the Hydrological Plan for the Hydrographic Demarcation of Western Cantabria 2015-2021, certified in 2019 for the implementation of the ecological flow regime in EDP Spain hydroelectric power plants, is at a very advanced stage, pending completion in Valdemurio, Tanes, Furacón and Priañes, once the execution of projects for the adaptation of the dam drainage bodies has been completed. Natural capital Spain As part of the Working group on Natural Capital in the energy sector created in 2019, contributed to the environmental impact rapid assessment tool developed for electricity distribution lines in ecosystem habitats, species and services; and assisted in decision- making when drawing sections of new lines (completed in 2021). In 2022 it took the opportunity to activate all the experience and knowledge shared in this group to prepare a guide document (which awaits completion) with conclusions for all the activities of the electricity sector that will serve as a basis for future work on the reclamation of natural capital in the environment of our facilities. 

Integrated Annual Report 2022 Performance Sustainability 139 In addition, in 2022, EDP continued to strengthen its public commitments in this area by: • implementing the commitments made under Act4Nature-Portugal, whose 2021 and 2022 results can be analysed in the biodiversity brochure 2020-2022. Act4Nature is an initiative led by the BCSD-Portugal and fostered by the biodiversity working group since 2020, where EDP is part of the Steering Committee and the Advisory Board • in 2022, this working group organised and presented the "I Natural Capital Conference", which took place in Lisbon on 23/11/2022 • implementation of the commitments made under the Brazilian Business Commitment for Biodiversity The Commitment - IBNBIO, whose results can be analysed in the Biodiversity Report 2020-2022 • membership in the Act4Nature-Portugal initiative, and subscribed to the ten common commitments and 12 individual commitments by 2030. By 2021, of the 12 individual commitments, ten have been reached or are underway, and two are yet to begin. From the EDP biodiversity agenda, the following initiatives stand out in 2022: In Brazil, another phase of project “Capibaxa Sweet Springs”, a partnership initiative with the Earth Institute, recovering 10 tributary springs in the municipality of Baixo Guando in Espírito Santo. The aim is to promote the recovery and conservation of water resources through the forest restoration of springs and the installation of five mini sewage treatment plants in rural properties. In Portugal, in the activity of electricity distribution, E-Redes celebrated the 20th anniversary of the Protection of Avifauna in the Distribution Network, a partnership that joins E-REDES and the Institute for Conservation of Nature and Forests (ICNF), Quercus, the Portuguese Society for the Study of Birds (SPEA) and the League for the Protection of Nature (LPN). Event that took place on 10 October 2022, when we looked back on this partnership and pondered the "New ideas in Distribution'' in the challenges and opportunities brought about by the compatibility of the economy´s electrification needs and the safeguarding of natural values (see more information in the Biodiversity Report). Also in the electricity distribution activity, partnerships with several bodies are highlighted through the LIFE program (European Union financial instrument for the Environment and Climate Action), focused on minimising the impact of existing high and medium voltage overhead power lines: • the LIFE LxAquila project was continued, focusing on the Bonelli eagle species, where 47 medium voltage network supports were corrected with combined solution, inversion from horizontal to vertical sectioners and also nesting deterrents • two projects were approved: LIFE PowerLines4Birds, focused on seven threatened target species (black vulture, Egyptian vulture, Iberian imperial eagle, great bustard, little bustard, golden eagle and roller), in 23 Special Protection Zones (Natura 2000 Network) in the Iberian Peninsula (14 in Portugal and nine in Spain), and LIFE SafeLines4Birds, directed at the White Stork in Portugal, and 12 other endangered species, both of which count on the participation of several partners in: Belgium, France, Germany, the USA and Portugal, in partnership with other utilities Operators of Similar Distribution Network and Electricity Transport. In 2022, work was developed to improve the existing fish transposition systems during hydropower production activities, and monitoring systems were implemented. (see more information in the Biodiversity Report). Prevention of pollution EDP assesses the potential effects on biodiversity of its main construction, operation & maintenance activities, where aspects related to soil, water, air and noise pollution are considered. This analysis ensures that they are covered by the environmental management systems put in place and makes it possible to systematise and optimise best management practice for mitigating impact on biodiversity across the group. (see more information in the Biodiversity Report). The following preventive operational actions regarding pollution in the context of biodiversity protection in electricity production and distribution activities stand out, namely: • programme of screening and elimination of oils with PCB • prevention of the production of waste and its hazards Sorting, storage and assurance of adequate final destination of waste produced In Portugal, EDP has cumula- tively achieved the extension of 1,371.7 km correction of critical distribu- tion lines for existing birdlife in protected areas and the Natura 2000 Network 

Integrated Annual Report 2022 Performance Sustainability 140 • replacement of transformers’ mineral oil, which causes hazardous waste, with vegetable oil • analysis of the cause of occurrences having environmental impact and identification of measures for rapid action in correction and prevention • implementation of noise minimisation measures • contractual environmental requirements from external service providers, with penalties applied if these requirements are not met, and • environmental training to employees with activities that impact the environment. 3.6.3.2.2. Circular economy The Circular Economy is one of the axes of the EDP group's sustainability strategy, constituting an important pillar of its Environment Policy. For EDP, the Circular Economy is based on the efficient use of natural resources from a life-cycle analysis perspective, with the objectives of: • Minimise the use of natural resources necessary for the proper execution of its activities • Efficiently optimise and manage internal products and services capable of leveraging the circular economy in its customers • Maximise the recovery of waste and its reintroduction into the economy as by-product. EDP´s strategic vision for the circular economy is based on three fundamental pillars: Reduction, Reclamation and Optimisation as a way to promote the increase of circularity in the business, implemented through seven priority axes of action (see figure to the side). EDP has set out four ambitious circular economy targets for 2025, contributing to its commitment to SDGs 8 and 12, promoting decent work and economic growth, and sustainable production and consumption (see table on the following page). To achieve these objectives, a corporate roadmap was determined, to which projects and initiatives developed by the different Business Units of the group contribute. In 2022, there are several best practices for circular economy, for each of the priority axes of action, which are detailed in the following table. KPI 2022 Promoting the Circular Economy TARGET 2025 74% Accelerating circularity in renewables in terms of operational waste and decommissioning >80% -66% Reduction of operational waste -82% 52% Increased rate of recyclability in the operation 85% -77% Reduction of water consumption -78%

The introduction of cork instead of conventional float materials, such as plastic, allows the replacement of a non- renewable material with a renewable material, neutral in GHG emissions in production and more favourable to biodiversity. Within the scope of the project, a life cycle analysis (LCA) was performed specifically to evaluate the impact of this type of floating photovoltaic project versus projects that use conventional floats. EDP Produção - Portugal Application of the Ecodesign Directive in the purchase of transformers in Distribution In accordance with the European Commission's Ecodesign Directive, tier 1 transformers have not been purchased since 1 July 2021. Its replacement by Tier 2 transformers will reduce energy waste by 10% compared to Tier 1. E-REDES - Portugal Energy storage system with batteries at solar farms Installation of batteries for energy storage in solar farms with the aim of improving the flexibility of electrical systems, thus incorporating greater renewable capacity. EDP Renováveis - Europe and Brazil Durability Reuse of buildings and infrastructure at the Sines plant under the GreenH2Atlantic hydrogen project Reuse of buildings and infrastructure so as to increase their durability and prevent the production of waste. In particular through: reuse of the water outlet; electro chlorination building; group 4 adduction water duct; group 3 and 4 rejection channels; breakwaters; water treatment system building; demineralised water tanks; cable track tunnel between the plant and the water outlet; buried nets; accesses, etc. EDP Produção - Portugal Digitalisation Transformers overhaul Reconditioning of transformers and the use of predictive analysis and remote monitoring of this equipment in real time, which allows an increase in the responsiveness and quality of service, and simultaneously increases the useful life of resources through dematerialisation processes. E-REDES - Portugal LIDAR system on power lines Use of LIDAR flights for maintenance and monitoring of lines, avoiding travel and saving resources. EDP Spain - Spain Resources enhancement Reclamation of wood resulting from the clearance of vegetation Reclamation of cut vegetation in between the lines subject to Secondary Network Fuel Management Strips, focusing on supporting the protection and preservation of biodiversity and carbon sequestration. E-REDES - Portugal Demolition waste reclamation Deactivations have a minimum reclamation rate of 90%. Waste recovery with clear resource savings in other industries (e.g., steel and iron) and filling materials (if we reuse uncontaminated construction and demolition waste in the environmental reconversion of decommissioning). EDP Produção - Portugal 

Integrated Annual Report 2022 Performance Sustainability 143 Axis of action Initiative Description Business Unit New business models Solar energy sales as a service Development of a business model as a service for solar, in which the management of panels made by EDP contributes to their better maintenance and, therefore, to an extension of their useful life, in addition to the fact that when the customer no longer needs them, they can be reused by other customers. EDP COMERCIAL and EDP Spain - Iberia Capacity building and raising awareness (Environmental Accreditation - The Environmental Management System carried out and certified in all operational facilities in Europe and Brazil, which allows the promotion of circular economy guidelines that increase innovation and overall process efficiency, along with awareness of the theme among employees and suppliers. EDP Renováveis - Europe and Brazil Training: Circulating at EDP Initiative that aims to internalise the concept of the circular economy in EDP through the training of employees, with a focus on the development of mindset and competencies. It includes three axes: (1) Introduction to the circular economy, for all employees, with the objective of internalising the concept; (2) Short immersion courses on specific circular economy topics; (3) Circular Economy Days, developing mentoring aimed at developing examples of circularity in the company's business. EDP Brasil - Brazil EDP gathers efforts to develop solutions so that its main waste materials can be used as by- products and raw materials for another industry, namely fly ash and coal slag which made up around 96% of the total waste materials recovered (362,848 tonnes). With regard to construction, operational activities and the maintenance of facilities, reuse is prioritised so that, when discarding, recycling is always considered as the first solution. In this way, contracts are established with licensed operators who transport the waste to the appropriate destination for recovery. Efficient waste management goes beyond the suitable disposal of waste and its incorporation into the economic circuit, by promoting its reintegration whenever possible. This management starts upstream, in design and in the choice of materials necessary for the functioning of operations. Water management EDP recognises access to drinking water and sanitation as a universal Human Right and assumes its responsibility in the pursuit of SDGs, in particular SDG 15, contributing to the sustainable use of freshwater ecosystem services, and SDG 7, seeking to ensure the supply of clean and affordable energy for all. Under its Environmental Policy, EDP is committed to mitigating its impacts, managing risks and promoting the ongoing improvement of processes, practices and performance through a collaborative approach with stakeholders for the sustainable management and efficient use of water. Water is a vital resource for electricity generation, particularly hydroelectric power, which is an important part of EDP's renewable generation portfolio and is crucial to its strategy of reducing CO2 emissions and mitigating climate change. Although, and contrary to the other activities of the organization, the use of water in hydroelectric production is not considered consumption, EDP monitors the volume of water managed in these assets, which has reached 112 million cubic metres, -44% compared to 2021\. This indicator depends heavily on the hydropower productivity index in Portugal, in which the water portfolio is more relevant, being the same 0.63 (vs. 0.93 in 2021), 37 p.p. below the average hydrological year. 

Integrated Annual Report 2022 Performance Sustainability 144 WATER CONSUMPTION (%, THOUSAND m 3 ) WATER WITHDRAWAL (%, THOUSAND m 3 ) The specific consumption of fresh water changed in 2022 (-25% compared to 2021), with the decrease in the EDP group's coal-fired electricity generation (10% vs. 2021), which is justified by the fact that the Pecém thermoelectric power station in Brazil has been shut down. EDP monitors potential shortages, water quality and sediments, as well as the impact of the management of this resource on biodiversity, for which it undertakes mitigation activities such as the release of ecological flows, the transfer and transport of fish, and support for scientific research on these topics. It is important to mention the fact that the Pecém thermoelectric power station in Brazil is located in a water stress zone, so EDP uses the World Resources Institute´s Aqueduct tool to assess its exposure to water risk at the hydrographic basin scale, then a local analysis is conducted considering quantitative information from national institutions and the experience of internal operational teams. Since 2010, EDP has responded to the CDP Water Security, where it provides a detailed description of its ongoing initiatives. In 2022, EDP achieved the highest performance level of this index (leadership) with a rating of A. 3.6.3.2.3. Climate change Prominently positioned at the forefront of energy transition, EDP recognises the importance of the electricity sector, and of its contribution to a low-carbon economy, as a solution for tackling climate change. Given the current context of climate emergency, as well as compliance with the global commitment established by the Paris Agreement and reinforced by the Glasgow Pact to limit the increase in global average temperature to 1.5ºC, EDP's contribution to combating climate change is realised through its Climate Action approach, embodied in the Climate Transition Plan (published in an autonomous document). EDP's Climate Action approach focuses on mitigation actions - with the aim of reducing greenhouse gas (GHG) emissions and adopting climate change adaptation plans in all regions and business units exposed to significant climate risks. These actions are supported across the board by innovation - which aims to promote the development of carbon-neutral technologies and increase energy efficiency; and by capacity building, increasing awareness and transparency on climate change, both within and outside EDP. This approach is the responsibility of corporate governance, which assumes a strategic role in the appropriate management of climate responsibilities and action plans, where it includes In 2022, EDP attained the level of higher performance (leadership) with the rating A CDP Climate Change CDP Water Security 32.7% 4,834 1.4% 213 65.9% 9,750 67.3% 9,964 Brackish Fresh Water stress Non water stress Fresh 11,275 1.7% Brackish 11,442 1.7% Salt 652,951 96.6% 

Integrated Annual Report 2022 Performance Sustainability 145 the identification, analysis and management of climate-related risks and opportunities (more details in Climate Transition Plan). EDP has publicly assumed a set of short, medium and long-term objectives and targets that support its decarbonisation strategy, approved by the Science Based Target initiative (SBTi) as being aligned with a decarbonisation trajectory of 1.5ºC. It has also committed to achieving carbon neutrality by 2030 for its scope 1 and 2 emissions. Despite ongoing efforts to reduce GHG emissions, there are residual emissions that cannot be eliminated. For these, EDP will offset them through the use of carbon credits. The following emission reduction targets are being validated by SBTi: SCOPE 2030 2040 S1+S2 [intensity] -95% -96% S3 [absolute] -45% -90% S1+S3C3 [intensity] -80% \- S3C11 [absolute] -45% -90% S1+S2+S3 [absolute] \- -90% EDP follows the recommendations of the TCFD (Task Force on Climate-related Financial Disclosures), disclosing information on governance, strategy, risk and opportunity analysis, metrics and objectives and financial impact of climate change on the company (Annex "EDP’s Alignment with TCFD Recommendations"). The EDP group publicly discloses its response to the CDP Climate Change questionnaire, in which it details its strategy and performance in the fight against climate change in line with the TCFD (CDP Climate Change EDP 2022). In 2022, EDP achieved the highest level of this index (Leadership A) in both the CDP Climate Change and CDP Water Security. 

Integrated Annual Report 2022 Performance Sustainability 146 Climate action mitigation Mitigation is directly linked to EDP's Business Plans, both on the supply side and on the demand side, with the aim of reducing global GHG emissions by implementing solutions based on four main pillars: In 2022, the first pillar was strongly influenced by the global energy crisis caused by the Russia-Ukraine war, which translated into an escalation of the price of natural gas on the international markets and conditioning the entire energy sector in Europe. In comparison with 2021 EDP observed: • a significant increase in electricity generation from coal-fired thermoelectric power plants in Spain (+ 64%) • the closure of coal-fired power plants in Portugal, together with the severe drought experienced until November - the Hydroelectric Capability Index (HPI) was below 0.7, led to a considerable increase in electricity generation in CCGT (+ 35%) • the net increase in renewable capacity (wind and solar) was only 1,320 MW. As a result of these extraordinary operating conditions, there was an increase both in primary energy consumption (+ 4% than in 2021), although emissions associated with electricity generation fell by 4%largely due to the shutdown of the Pecém coal-fired power station in Brazil. EDP reports its GHG emissions in accordance with the GHG Protocol Corporate Accounting and Reporting Standard (categories detailed in annex table). In summary: • scope 1 emissions: includes stationary emissions from thermoelectric power plants, which represent 99.7% of the total, as well as emissions from the vehicle fleet, fugitive emissions (SF6) and those corresponding to natural gas consumption in buildings. In 2022, they totalled 9. 4 MtCO2e, 4% less than in 2021 • scope 2 emissions: refer to electricity consumption, including losses in transport and distribution networks (the part produced by third parties), internal consumptions in power plants and consumption in administrative buildings supplied by third parties. In 2022, they totalled around 0.47 MtCO2e, 41% less than in 2021, largely due to the significant reduction in emission factors in Portugal and Brazil, affecting the contribution of losses in the distribution networks • scope 3 emissions: comprise all remaining indirect emissions upstream and downstream of the value chain, not accounted for in the other scopes. They essentially include emissions associated with purchased goods and services, energy and fuel- related activities and the sale of gas to end customers. The total value of scope 3 emissions reached 9.3 MtCO2e, 10% less than in 2021, essentially due to the reduction in the categories of sale of gas to end customers and energy and fuel related activities. SCOPE1, 2 AND 3 EMISSIONS (ktCO2e) 1\. Continued reduction of production from coal-fired power plants (by 2025) and natural gas (by 2030). 2\. Increase in renewable power, with the public objective assumed by EDP of reaching 100% in 2030. 4\. Promoting innovation aimed at mitigating the effect of climate change, contributing to the energy transition to a low carbon economy. 3\. Strengthening electrification and promoting energy efficiency, favouring the supply and demand of renewable energies and sustainable mobility solutions. 21 550 18 931 23 159 18 429 14 363 9 304 9 819 9 405 982 547 802 602 846 594 791 469 14 623 12 469 13 039 11 334 11 730 11 572 10 304 9 279 2015 2016 2017 2018 2019 2020 2021 2022 Scope 1 Scope 2 Scope 3 

Integrated Annual Report 2022 Performance Sustainability 147 The 7% reduction in Scope 1 and 2 emissions, combined with the slight increase in electricity produced (+ 2.6%), meant that specific Scope 1 and 2 emissions decreased by around 9% compared to 2021, settling at 160 gCO2/kWh. SCOPE 1 AND 2 SPECIFIC EMISSIONS (gCO2/kWh) The production of electricity at renewable energy power plants by replacing fossil-based thermoelectric production in the country where they operate avoids the emission of greenhouse gases in an amount corresponding to that which would be emitted by a mix of the existing thermoelectric portfolio in that country, producing the same electricity. In 2022, avoided emissions amounted to 22.7 Mt CO2e, 4% less than in 2021. The decarbonisation strategy also has an impact on improving energy efficiency along the value chain, contributing to the reduction of upstream primary energy consumption and, on the other hand, to greater efficiency in the end use of energy (third pillar), avoiding GHG emissions. In the car fleet, the percentage of electric light vehicles rose from 13% to 15% in 2022\. It should be noted that EDP has assumed a commitment to electrify more than 40% of the light vehicle fleet in 2025 and 100% in 2030. The fourth pillar regarding innovation is developed in chapter 3.6.2.3.2. Climate action adoption Ensuring the resilience of its electricity generation and distribution infrastructures is one of the priorities of EDP's climate action. EDP has set a goal to have Adaptation Plans in place in its Business Units by 2022 which ensure the resilience of infrastructures that may be exposed to extreme events of greater intensity and frequency, given the reality we know today. By the end of 2025, the global commitment is to achieve 100% implementation of these adaptation plans. To this end, the common corporate methodology supports the Business Unit plans already in place and the evaluation and quantification of physical risks are consolidated at corporate level in accordance with EDP's risk taxonomy, aligned with TCFD Recommendations. The level of exposure of EDP's infrastructures to physical climate risks is assessed considering the relevant climate variables, the short, medium and long -term IPPC scenarios and level of regionalisation. In addition to supporting the sensitivity analyses of the group's business units in the implementation of climate change adaptation plans, the physical risk analysis serves to support the decision for new investments.

Scope 3 of everything Recent years have seen a profound evolution in the regulatory framework and societal expectations regarding supply chains, with companies now assuming responsibility beyond their direct suppliers and subcontractors and into human and labour rights, integrity, cybersecurity and circularity. Companies should manage their scope 3 emissions with respect to everything, not just CO2. The renewable sector is particularly exposed to this demand because of the hopes for decarbonisation and access to electricity placed in it, and because its supply chain is based on cutting-edge technology, consuming energy and natural resources in a global market that is too concentrated, with numerous supplier layers, and lacking the required transparency. In particular, the photovoltaic and semiconductor sector is one of the most exposed to these demands. Another challenging year 2022 was marked by Russia's invasion of Ukraine, with economic and humanitarian consequences including rising energy and food costs, and an ever-present climate crisis whose effective mitigation will require global transition to a low-carbon economy. Inflation accelerated in many countries as a result of pandemic-related disruptions combined with consumer demand and higher commodity prices. As a result, economic recovery plans focused on re-industrialisation are emerging simultaneously in the US and the EU, accompanied by increasingly demanding legislative packages for the environment and human rights. This whole context is increasingly defined by the interaction of complex disruptions with disparate origins and long-term consequences for which organisations in general are not fully prepared, forcing an adaptation of the way risk is managed in this new environment. In this sense, the concept of resilience, particularly in supply chains, gains relevance, as it is seen as the ability of organisations to cope with adversity, adapt and continuously accelerate as disruptions and crises arise over time. For an organisation like EDP, present in multiple markets and business areas, supply chains hide interdependencies, potentially leading to crises, where hidden interruptions may arise, unexpectedly impacting the company's business plan. However, the changes introduced during the COVID-19 pandemic, and more recently with the war in Ukraine, have also represented a new impetus for accelerated growth: the shift to digitalisation, new hybrid working models, rethinking supply chains and accelerating climate change investments. 2022 is therefore representative of the capacity to reinvent and innovate in the face of disruption.

Integrated Annual Report 2022 Performance Sustainability 149 Direct Challenges faced by EDP Procurement In 2022, procurement faced market shortages and sharply rising fossil fuel costs and confronted the difficulties of timely supply of photovoltaic panels, electrical and IT equipment, ensuring with its partners the proper accreditation of entry into each country and managing customs blockages in the US. At the same time, procurement met the growing number of EDP investment projects, portfolio realignment and geographical expansion, which required structural organisational measures. Likewise, regulatory changes have required measures to update processes and procedures. EDP worked with 4,199 suppliers and bought over 10 billion euros, registering occasional, unforeseeable, and contained negative occurrences arising from established contractual relationships. The level of occupational accidents in the subcontracting of construction, installation and maintenance of equipment persists as one of the top priorities. Supply chain - hot topics Reporting Directive: the EU has approved new transparency and reporting rules for large companies. The measure will boost comparability between companies and favour procurement processes through the standardisation of indicators. Due Diligence: in anticipation of the European Due Diligence Directive, companies are already embracing the substance of the law internally, cooperating to define sector standards and audits. DNSH and minimum safeguards: the concepts of Do No Significant Harm and minimum safeguards have become the letter of the law with the European taxonomy. The funder must assess the negative effects of the projects it is financing on human rights, climate, biodiversity, water and material consumption. Direct and indirect Effects. Scope 3: the SBTi initiative has become the benchmark for assessing decarbonisation trajectory and Scope 3 emissions must be calculated by all companies War and monopolies: The invasion of Ukraine and the US-China geopolitical tension have shown the energy imbalance between the powers. The West has decided to accelerate renewable energy and reindustrialisation. Forced labour: The complicity or alienation of companies in relation to forced and/or unprotected, poorly paid, segregated, repressive labour has become a frequent reason for scrutiny in dialogue between companies and suppliers. Material scarcity and innovation: Uncertainty about timing, quantities, prices and continuity of access to suppliers is being accompanied by a high level of innovation and diversification in the electricity sector. 3.6.3.3.2. Identification and mitigation of Procurement Risks Through criticality analysis, the EDP group identifies and segments the potential risks associated with each type of specification. The analysis is carried out using the Sustainability Matrix (EDP Sustainability Protocol), which combines the relevant risks of the activity, identified by consulting stakeholders and attributable to the sector, with the characteristics of the specifications. Based on this criterion, the following was analysed: financial, business relevance and continuity; dependence and autonomy; access to data; facilities; customers; local communities; cybersecurity; emissions potential; waste; environmental accidents; accidents at work; integrity and compliance; human and labour rights. Once the risks of each type of purchase have been identified, non-negotiable clauses are included in the specifications that establish the minimum qualifications that suppliers must meet, as well as the rules for monitoring execution of the contract. Suppliers that submit proposals only enter the negotiation phase after due diligence of integrity, legal and ethical, financial, technical, social and environmental compliance is carried out. Through the application of Go/No-go rules in the selection of suppliers and contractual clauses that include monitoring, audits and performance assessment, EDP ensures that it works with low-risk suppliers with skills appropriate to each activity´s inherent risks. Due Diligence to Suppliers EDP started implementing ESG Due Diligence in 2017, in accordance with the United Nations Ruggie methodology. As of 2020, with the approval of amendments to the Hu- man Rights Policy and the ESG Protocol for Suppliers, the Due Diligence process was extended to all business units.

However, in the equipment and technology chain the identification of specific indirect suppliers is unfeasible until an international standard for traceability and origin of materials can be established (see Action Plan). ESG DUE DILIGENCE LAYERS See chapter “Promote and respect Human Rights”. 

Integrated Annual Report 2022 Performance Sustainability 151 EDP’s core supply chain There are four ESG risk segments in the supply chain that correspond to the purchasing categories of the value chain. In 2022 there was a very significant increase in the volume of purchases, which rose from EUR 5.7 billion to EUR 10.1 billion. The increase in fuel prices explains 50% of the growth and the decarbonisation investments arising from the Business Plan justify the rest 3.6.3.3.3. Supply Chain ESG Goals In 2020, EDP expanded the sustainable procurement targets to define the obligation of strategic alignment of suppliers with EDP's objectives. In fact, pursuing goals of carbon neutrality, circularity, biodiversity gains, respect and promotion of human rights, EDP needs its supply chain to commit to the same practices and contribute to transparency, traceability, verification of impacts and the reduction of the negative ESG footprint.

Integrated Annual Report 2022 Performance Sustainability 153 Javier Rodríguez Diez Chief Sales Officer of Vestas Wind Systems “Our partnership with EDPR goes beyond a pure commercial relationship: for the last 15 years, we have worked together to contribute to the deployment of wind energy across the globe. We have successfully executed very complex projects across different geographies and that is only possible when two leaders work passionately towards the same goal. Our commitment to accelerate the energy transition to help tackle climate change, our shared values and a historical partnership built on trust allow us to continuously innovate and reinforce best practices together. We also support one another to find optimal solutions for any challenge that may arise, to maximise the quality of our products, minimise risks, decarbonise our operations across our entire value chain, and of course, to have a positive impact on the communities where we operate. Our collaboration through the initiative Keep It Local to train people living in rural areas to become service technicians is a testament to our willingness to maximise the value we offer to society through job creation. I know we still have a long way to go, and I feel proud to have been myself part of this exciting journey along with EDPR. We are grateful for their trust in our people and in our solutions.” Javier Rodríguez Diez 

Integrated Annual Report 2022 Performance Sustainability 154 3.6.3.4. Respect and advocate for human rights Alignment with the SDGs Objectives KPIs 2022 Targets 2025 Protect Human Rights in the supply chain, according to the Ruggie methodology through Due Diligence, audits and performance assessment 100% 100% Carry out human rights impact assessments on the development of infrastructure projects, following the Ruggie methodology 100% 100% Management approach EDP pursues a policy of full respect for human and labour rights and, at the same time actively promotes universal human values. The commitments are set out in the Human and Labour Rights Policy that was updated in 2021, in conjunction with the Code of Ethics, the Stakeholder Relations Policy and the Supplier Code of Conduct. In addition, the EDP group also has Diversity and Voluntary Investment in Community policies. The Human Rights Policy covers the entire EDP group, has been approved by the Board of Directors and has a dedicated Committee. The Policy is prescriptive in nature, identifies the references, standards and international conventions to which it is subject, establishes the strategic principles, specifies the principles for action, assigns responsibilities, determines obligations and management bodies. The Policy details operational commitments, its workings, complaint and communication channels, reporting and training obligations and extends obligations to suppliers. In particular, the Policy sets out Due Diligence procedures, implementing the Ruggie and OECD methodology, and anticipating the EU Due Diligence directive. The report on Human and Labour Rights is carried out in an integrated manner through a specific annual report. In this report, the subject of human rights is separated into several sections and should be read in conjunction with the Ethics and Integrity, Suppliers, People and Prevention and Safety reports. The annual Human and Labour Rights report aggregates all the themes, publishes the country and risk maps, as well as the specific risks of each stakeholder group. Identification of risks The analysis of the risks related to the respect for human and labour rights is carried out by assessing the country risk, the local risk and the specific risk of each activity according to the nature of the project, informed by the sector's risk map. Depending on whether we are considering new investments, the creation or modification of infrastructures, contracting suppliers and other counterparties, or operations with customers and employee management, specific risk control and mitigation measures are implemented. The EDP group's activity is exposed to four main risks for negative impact on human rights. Stakeholders Risk Indirect suppliers to the electricity sector Failure to follow ILO Conventions Service providers (contractors) Accidents at work Local communities of coal-fired plants to be closed Unemployment Vulnerable local and indigenous communities Negative impact on the land Failure to follow ILO conventions Fundamental labour rights are enshrined in eight International Labour Organisation conventions: freedom of association and the effective recognition of the right to collective bargaining; the elimination of all forms of forced or compulsory labour; the effective abolition of child labour; and the elimination of discrimination in respect of employment and occupation. EDP faces indirect risks of failure to respect fundamental labour rights relating to the extraction and production of the materials necessary for the value chain of manufacturers of electrical technologies. These risks occur several levels upstream of the direct suppliers and focus on internationally identified regions. Accidents at work The risks of accidents at work are manifested in operations and construction work, and in the installation and maintenance of equipment, carried out mainly in outdoor spaces. When contracting suppliers, the EDP group always ensures full prior verification of compliance with the fundamental conventions of the International Labour Organisation, as well as requiring proof of satisfaction of remuneration conditions, and monitors compliance with the Supplier Code of Conduct throughout the contract, as detailed in the chapter on Supplier Management in this report. 

Integrated Annual Report 2022 Performance Sustainability 155 Unemployment In the field of new investments and infrastructures, the main risks are related to guaranteeing the rights of local communities, namely property rights, which are typically rights of use that are not embodied in full ownership, such as the situation of indigenous territories, fishing or hunting areas, protected landscapes and land use rights. In these cases, the construction right authorised by the public authorities can be substantially challenged by the communities. Negative impact on communities Likewise, the installation or modification of an infrastructure may have effects on local social dynamics or ecosystems. For these reasons, the EDP group normally conducts social and environmental impact studies and opens communication channels in order to ensure proper management of projects, including full consultation with stakeholders, as established in its policies. Negative Occurrences The procedures established ensured that, throughout 2022, as in previous years, the EDP group was not subject to accusations or suspicions of violations of fundamental human and labour rights. However, occasional occurrences were registered and dealt with, being neither structural nor recurrent and often related to individual behaviours or situations leading to complaints that were solved within the ethical process and, when justified, gave rise to corrective measures, penalties or reinforcement of established procedures. Among the dozens of EDP projects, there are investments with a significant community impact, such as the São Manoel hydroelectric plant in Amazonia, the transmission network in Brazil and the wind project in Colombia. Objectives and action programmes OBJECTIVE 2020 2021 2022 TARGET 2025 Protect Human Rights in the supply chain, through due diligence, audits and performance assessment 100% 100% 100% 100% Assessing human rights impacts in the development of infrastructure projects, according to the Ruggie/OECD methodology 100% 100% 100% 100% In addition to the management system that guarantees and implements objectives, EDP has action programmes directed at the most salient risks. Risk Action Programme Failure to follow ILO Conventions Extension of Due Diligence to Indirect Suppliers Solar Stewardship Initiative \- due diligence standard for the solar sector Bettercoal \- due diligence standard for the mining sector Accidents at work Global PlayitSafe Programme Unemployment Just Transition Local Reinvestment Plans Negative impact on the land Local Community Development Programme Supply Chain Traceability and Due Diligence Programme EDP systematically scrutinises any evidence of human rights violations that may be related to any counterparty, and especially to the electricity sector and decarbonisation, through a due diligence process on legal compliance, integrity, human and labour rights to counterparties with deals above €25,000. This process covers 99% of the purchasing volume and results in the exclusion of those who do not guarantee compliance with national and international standards. Additionally, for the suppliers of the electricity sector’s value chain, and according to specific risk maps, there is scrutiny on climatic and environmental issues, on skills and sustainability management practices, financial risks and business continuity, cybersecurity, prevention and safety management, and quality, among others. Once the contractual relationship has been established, where the ESG requirements are converted into contractual clauses, EDP monitors, audits and evaluates the performance of its critical suppliers. However, the Due Diligence process has been directed at contracted or yet-to-be contracted suppliers. Currently, regarding the relevant sectors for the value chain of the electricity sector, EDP aims to extend Due Diligence for indirect suppliers. Conducting audits of the suppliers of 

Integrated Annual Report 2022 Performance Sustainability 156 suppliers is an emerging issue on the international agenda - it requires time, a change in mentality, and collaborative work from companies. EDP is currently working on this issue, discussing with its suppliers exposed to risks, modifying contractual clauses, requesting equivalent commitments and the principle of independent auditing. In this area, the photovoltaic panels sector is a priority, insofar as it is a strategic technology in EDP's business plan and is exposed to geopolitical conflict, is affected by accusations of forced labour, customs controls, price rises and logistical disruptions, generating significant medium/long term uncertainty. Believing that extending the practice of due diligence to indirect suppliers depends on companies from each industry sector working together, EDP is a co-founder of the Solar Stewardship Initiative, a Solar Power Europe programme, which has established a code of conduct and auditing principles specific to the solar sector. Auditing of companies, especially those exposed to charges of colluding with forced labour, is the action plan for 2023. PlayitSafe The persistence of serious occupational accidents of people working for companies subcontracted for electricity infrastructure construction and maintenance services is also at the top of EDP's priorities. The programme is detailed in the chapter on Prevention and Safety. Respect for local and indigenous communities The implementing of new technologies on the Energy Transition requires the approach of new territories, often sparking issues of distrust and fear with the building of new facilities for renewable energy generation. In the United States a most recent lawsuit was filed in December ’22 against Wildcat Creek and EDPR NA and reported at RepRisk, although the operation is functional, and no community complaints were registered at the regular auscultations or grievance line activation. Differently from the opposition groups active in Rolling Uplands Wind Farm, still at Project phase, where all assessments required were published and no risks identified. Still, the community is worried about viewshed impacts and EDP works its way through ongoing dialogue with project stakeholders, local authorities and attendance at public meetings. The same mistrust of the newcomers led Village of Misenheimer officials (where the Misenheimer Solar Park is being built) to delay issuing a permit on clearing trees, while waiting to become familiar with the project, and ensure EDP was abiding by environmental agency requirements. Throughout, the dialogue with the Village is ongoing, with public events hosted in the community. Judy Waligory Landowner When the Maple Ridge Wind Farm came to New York state, landowners like Judy Waligory worked with EDPR NA to host turbines on their land and bring new opportunities to their rural community. “My husband’s family farmed this land, and we now have eight wind turbines on our property. EDPR’s wind turbines have helped us stabilize our family’s income. We use the income from the turbines for living expenses and planning for the future. I have two children and five grandchildren, so this will help make their lives a little bit better. The income that families, towns, school districts, and municipalities get from the wind farm really benefits everybody. It’s not just the landowners—it’s the entire community. Many of the EDPR employees have lived here for a long time, so this is their neighbourhood. They want to see the whole community be a success. We’re able to provide more services for children in this school and better services for taxpayers. It feels good to contribute to green energy to help not only our own community and our country, but also the entire world. It’s just a small part of the picture, but it’s our part.” Judy Waligory, Landowner 

Integrated Annual Report 2022 Performance Sustainability 157 Other countries are going through the same fear of the new, such as Colombia where the operation is at the building phase and the indigenous region of the Wayúus has faced group protests: EDP is committed to develop long-term programmes for the territorial and socio- economic enhancement of these communities, in full compliance with the obligations arising from the socio-environmental licensing and acting with full respect for the legislation and indigenous rights protection standards. The implementing of the programs, projects and assumed commitments will be due with the assumed proactiveness, dialogue and commitments to the people and local authorities. Collaboration with local associations and institutions has been reinforced, to understand local people needs and decide according to their priorities. The communication channels are operational and a total of $ 9,276,000 COP on food and essential commodities was donated to the “Shoshinchon community”, affected by weather issues. In Brazil the São Manoel Hydroelectric Power Station has been exposing EDP to impacts arising from interference in the territories historically used by the Kayabi, Munduruku and Apiaká ethnic groups, made up of around 1,400 people living in 19 villages on the banks of the Teles Pires River. As mitigation measures and environmental compensation for the benefit of these peoples, the Indigenous Components of the Basic Environmental Plan of UHE São Manoel (PBAIs), were prepared respecting the specificities/particularities of each indigenous people, being constituted in a long participatory process of dialogue that was monitored and approved by FUNAI at all stages of development. Each PBAI is contemplated with the execution of 17 programs that aim to improve the quality of life of these peoples. For the implementation and monitoring of the programs, Management Councils were created with representatives from the Company, FUNAI and each of the indigenous communities involved. The execution is prioritized around the execution of actions linked to subsistence activities, such as: Program for Strengthening Indigenous Organizations, Program for Identification and Management of New Sources of Non-timber Forest Products, Environmental Project for Management and Conservation of Tracajá, Program for Monitoring Chelonians and their Reproductive Habitats, between others. The construction of one school, two flour houses, a health support housing facility and Basic Indigenous Health Units in the Papagaio and Bom Futuro villages of the Munduruku people as well as in Aldeia Três Maria I and III Povo Apiaká resumed. 2022 continued implementing the granting of higher and technical scholarships, within the scope of the Program for Strengthening Indigenous Organizations. 38 scholarships have already been awarded. Art and handicrafts are being promoted through generation teaching: The pieces produced are being marketed in partnership between the artisans and the Indigenous Associations. An Integrity Management Support Program was implemented throughout 4 million hectares identifying the pressure vectors, such as prospecting activities and agricultural expansion that act with actions direct impact, mainly on deforestation. The development of the Community and Nature Integration Project, inserted within the Environmental Education Program at UHE São Manoel, was constituted from the realization of the Participatory Evaluative Diagnosis that prioritized the involvement of the local population. Facing the identified risk of dam breaking, new training was promoted through the workforce and inhabitants, as well as alarm systems and personal equipment reinforced. This same risk was identified at UHE Cachoeira (Amapá) Human Rights and Labour Assessments, and again an alert system was created through sirens. Cachoeira Caldeirão has developed social projects in partnership with Instituto EDP all year long. In general, projects were carried out to meet the social needs of people in situations of vulnerability, especially those most affected by the pandemic. Work accidents with employees or third parties were identified at Gielly Nayara Euzebio Arreco / Valeria Lopes Pereira / Kassio De Souza Kuster (EDP Espirito Santo) and Rafael do Prado grids: there were no complaints through grievance or auscultation, but group protests arouse when facing difficulties as problems with invoices, Charge for irregularity, Reading mistakes, Deadlines, Consumption Variation, etc. EDP is providing specific education as a new path to fight these vulnerabilities, and reinforcing social projects around health, entrepreneurship, sports and culture throughout the year, bonding the communities with the operation. Negative events The established procedures ensured that, throughout 2021, as in previous years, the EDP group was not subject to accusations or suspicions of violations of fundamental human and labour rights. However, occasional occurrences, which were neither structural nor recurrent, were recorded and dealt with, often related to individual behaviours, and translated into individual complaints that were endorsed and solved within the framework of the ethical process and, when justified, gave rise to corrective measures, penalties or reinforcement of procedures. 

Integrated Annual Report 2022 Performance Sustainability 158 Just transition The closure of power plants will always be both a sign of Energy Transition on the path to NetZero emissions, as it will always leave the trail of unemployment, economy depression and social challenging times to local communities. That’s why Just Transition must be the moto for this commuting: ensure decarbonization while mitigating all the outcomes of the coal shutdown. EDP is a world leader on energy transition, assuming its responsibilities towards the communities where it acts. Communities are engaged from a close and human perspective, promoting local development as a tool for the implementation of Human Rights. Our commitment is to fight Climate change, striving for NetZero leaving no one behind. EDP worked closely with the European Union institutions in to fasten the policy making, the funds and the acts protecting the energy transition. Several steps were taken at stakeholder engagement level by the EDP group towards the policy makers of the European Union: • July 2022: Joint letter with ENEL and Iberdrola, pushing for a rapid adoption of H2 Delegated Act. EDP on LinkedIn: Delegated Act - Joint Letter • letter to the EC with EDP Positioning on RePowerEU: supporting RePowerEu strategy and calling for a rapid adoption of H2 Delegated Act • response to Commissioner of Energy Kadri Simson’s response to EDP letter • June 2022: EBD member meeting with Commissioner for Innovation and Research Mariya Gabriel • October 2022: Letter with environment groups and civil society calling the EC to publish h2 delegated act • November 2022: Business Letter Urging the Commission to Issue a Strong RFNBO Delegated Act promoted by Google and other partners In this letter, EDP claimed an hourly correlation of consumption with renewable electricity generation for electrolytic hydrogen to justifiably be named renewable, geographic correlation in terms that hydrogen and renewable electricity production should occur within the same geography and the introduction of the principle of additionality. • meeting with the cabinet of VP for the EC, Frans Timmermans, on the H2 delegated act. In Sines (Portugal) the power plant began its closing process in January 2021, and a social programme “Futuro Ativo Sines” was put together, designed as a Fair Transition tool for the southern Portuguese region. The numbers evolved in 2022 showing the success of its implementation: EDP website public info on the Programme also disclosed at Sines Municipality site on EDP social Programme. A support office was put together with the Municipality and the National Institute for Skilling and Employment (IEFP): 111 registrations were held there, from 128 ex-workers that were registered at the IEFP. 67% are now working; 4% still under support from the Institute; 9% retired or are under health leave, and 20% undertook reskilling programs. 19 social entities received material from the dismantled plant; and 11 local ONG received from the Fund created to support the region, EDP Solidária Sines, a total of 141,000€. A reskilling program was created and an entrepreneurship scholarship created: EDP website on the entrepreneurship skilling also public at Sines Public Technological school site, on the entrepreneurship skilling. The case study of Sines inspired and fed the World Economic Forum toolkit for the Coal to Renewables engagement. Presented at the Davos meeting in 2022, the Programme won the Community Involvement Program of the Year at Environmental Finance's Sustainable Company Awards 2022. Throughout 2022, EDP Spain engaged in its path to a Just Transition: • at Aboño, the H2 “fase 150MW” proceeds with the Basic Project and has started the environmental processes ESIA and MS AAI. The Natural Gas exchange is building its Basic Project, and already started the environmental procedures ESIA and MNS AAI. There’s a Syncronous Compensator being studied for implementation after Aboño 1 is definitely closed. Side-by-side with the technical transition, the social process was engaged to focus on communities: The municipalities of Carreño, Gozón, Corvera de Asturias, Llanera y Villaviciosa had an entrepreneur program called ENTAMA, previous to EDP Spain but now focused on the JT regions; the recovery of rural paths and ecosystem services was established by the Mi Entorno program (Mi Entorno program) • at Soto de Ribera, the H2 “fase 5 MW” has its Basic Project being completed and has started the environmental procedures ESIA and MS AAI. The synchronous compensator 

Integrated Annual Report 2022 Performance Sustainability 159 is being studied and will only apply after the closing of Soto 3. Storage: several distinct long term technology approaches are being studied. Socially, over 18,000€ were invested in upskilling (EDP + Joven) through technological scholarships to 75 young men also on the municipalities of Ribera de Arriba, Morcín, Riosa, Quirós, Teverga, Mieres, Aller y Lena, along with other programs recovering the Nalón River or the planting of trees • in Los Barrios and Puente Nuevo, those programs (EDP + cerca; ENTAMA; mi entorno) were also applied, in order to reinforce the social network and the communities affected by the energy transition. Scholarships for electrical skills were very much appreciated by young people in those areas. Championing Human Rights programme The active promotion of human and labour rights is an integral part of EDP's strategy. The approach and programmes to promote human and labour rights are dealt with in depth in the People chapter and the Social Investment chapter. Through the Social Investment Policy, according to the B4SI methodology, in alignment with the global priorities of the United Nations expressed in the Sustainable Development Goals, EDP gives priority to social inclusion programmes, in particular directed at vulnerable communities, for the development of skills, and for energy inclusion, either through measures to combat energy poverty or through energy access programmes for populations not connected to electricity grids. 

Integrated Annual Report 2022 Performance Sustainability 160 3.6.3.5. Voluntary investment in the community 3.6.3.5.1. EDP group’s social investment – strategic vision The EDP group actively contributes to the sustainable development of the communities in which it operates worldwide, through its own social investment and collaborative initiatives, donations and volunteering. As social impact is a strategic pillar of the EDP group, these initiatives aim to meet social needs in line with the group's core themes, namely investment in fair energy transition projects which should represent around 45% of investment by 2025. The Fair Energy Transition projects include support for energy access, energy inclusion and communities impacted by the closure of thermal power plants, projects aimed at protecting natural heritage and biodiversity and also projects promoting energy efficiency and renewable energies, contributing to decarbonisation and combating climate change. On the other hand, the group's social investment strategy is also based on Culture, with the mission of promoting access to culture, stimulating art and protecting cultural heritage. Cultural projects are projected to represent around 30% of investment by 2025. In parallel and recognising the need to continue to support projects that respond to other social needs in the communities where EDP is present, part of the annual budget is earmarked for investment in various areas, such as training, health, social inclusion and response to emergency situations, among others. These Pillars are aligned with the Social Investment Policy at edp.com/yes In 2022, the EDP Y.E.S - You Empower Society brand was created, whose main objective is to communicate to the various stakeholders of the EDP group the social investment projects developed in the countries where EDP is present. The projects are classified into five main Pillars: Energy, Planet, Skills, Culture and Community, which are framed within the thematic focuses of EDP's social investment strategy. For more information on the social investment projects that are part of each EDP Y.E.S pillar and the respective social investment focused, please see the EDP group Social Investment Report. THE FRAMEWORK OF THE EDP YES PILLARS IN THE SOCIAL INVESTMENT THEMATIC FOCUSES 3.6.3.5.2. Voluntary contributions – application of the B4SI methodology EDP uses the international methodology B4SI - Business for Societal Impact to characterise and assess its voluntary investment in the community, which accounts for most of the investment made in this area (98%). This model promotes alignment between the purpose of companies and social needs, facilitating the structuring of priorities and reflecting on their results and benefits for the communities. In 2022, from a B4SI perspective, voluntary investment in the EDP group's communities was 31.2 million, supporting the projects of 634 entities, resulting in 3.2 million direct beneficiaries. Of this amount, 94% was classified as strategic, 3% as not strategic and 3% as commercial initiatives. Monetary contributions were the main form of contribution (90%), followed by in-kind contributions (9%) and time contributions (1%).

Integrated Annual Report 2022 Performance Sustainability 161 contributions, equivalent to € 261 thousand, correspond to EDP volunteer work initiatives carried out during working hours. Investment in Education was primarily directed at skills development projects, access to education for disadvantaged people, support for entrepreneurship and job creation. The investment in Health was directed at supporting health institutions and health professionals (equipment, support for health research, among others) and the investment in Emergency Response was made in projects that required a rapid and coordinated response (for example, support for the Ukrainian population, alleviating the consequences of the military conflict with Russia). Investment in Economic Development gave priority to energy access projects for communities without access to the electricity grid, with the A2E Fund standing out. Projects for social inclusion and the fight against energy poverty contributed to the investment in Social Welfare. Voluntary investment in the environment was carried out through projects to promote biodiversity, decarbonisation and climate change awareness-raising. In turn, the investment in Art and Culture gave priority to projects providing access to art and culture, and those preserving and promoting cultural heritage. 3.6.3.5.3. Mandatory contributions In addition to voluntary contributions, EDP also invests in the communities in which it operates through mandatory contributions. These types of contributions correspond to support for projects arising from offsets, commercial/legal levies or compensatory measures. In 2022, the compulsory investment in the communities of the EDP group was € 397 million (1.3% of total investment in the community) supporting 4 entities. Although with less weight than voluntary contributions and not recognised by the B4SI methodology as social investment, these contributions promote the sustainable development of the communities where EDP operates and, at the same time, are an important instrument to obtain the social license to operate in territories where new EDP infrastructure is to be built or new markets are to be entered. 3.6.3.5.4. Contribution to the SDGs In addition to contributions through its operations/business, the EDP group also contributes to the Sustainable Development Goals (SDGs) through its social investment programmes, prioritising goals 5, 7, 8, 9, 11, 12, 13, 15 and 17, in accordance with the Social Investment Policy. EDP reports its contribution to the SDGs not only at the level of the SDG objectives and targets, but also at the level of the indicators set by the United Nations. In 2022, of all the voluntary contributions recognised by the B4SI methodology, EDP supported projects that contributed to the SDGs with an investment of € 15 million (48% of total voluntary contributions) supporting projects of 512 entities, resulting in 1.7 million direct beneficiaries.

Integrated Annual Report 2022 Performance Sustainability 162 3.6.3.5.5. Volunteer work strategy EDP Volunteer Work is a fundamental pillar of the company's relationship with communities and, at the same time, contributes to the development of employees, expanding the purpose and meaning of their activity. The Volunteering Programme’s areas of intervention are aligned with the EDP group's Social Investment Policy and focus on social inclusion, empowerment, energy inclusion, biodiversity and climate action. Over the years, the Volunteer Programme has attracted a growing number of participants, in particular because it allows the allocation of hours to the various initiatives to be reconciled with working hours, reinforcing the important role of volunteering for the EDP group. The aim is to achieve a 30% share of the EDP group's Headcount (HC) by 2023. In all the different actions and projects promoted throughout 2022, 3,626 volunteer employees participated (27% of the company's HC), contributing 10,551 hours during working hours and 2,699 hours outside working hours. Given the inclusive nature of the Volunteering Programme, 283 EDP Friend volunteers (company retirees, friends, family and partners) were also involved, contributing 618 volunteer hours. In total, in 2022, the EDP group Volunteering Work Programme involved 3,909 volunteers, making a total of 13,868 volunteer hours. In 2022, the main focus of the Volunteering Programme was to provide an effective response to the main challenges identified in the volunteering strategy defined for 2022-2025, in particular communication, awareness raising and the involvement of leaderships on the subject of volunteering, as well as working on new ways to recognise and involve more volunteers in its mission. Additionally, in 2022, the Programme sought to stimulate more volunteering actions for skills related to energy, given the relevance of this type of volunteering that places the individual talents and skills of employees at the service of the community, having the potential to produce greater and longer-lasting social impact. There has been a clear commitment to this type of volunteering, and in 2023 it is intended to strengthen this component further, particularly with projects that contribute to fair energy transition. In 2022, worthy of mention was the 2,556 hours in skills-based volunteering projects (19% of total volunteer hours) carried out by EDP employees, of which 2,439 hours took place during working hours. Over the last few years, the EDP group has also sought to provide an integrated and expeditious response to emergency situations that ravage the world we live in and affect people and communities, acting in partnership with organisations on the ground. In light of the armed conflict in Ukraine, which began in 2022, the EDP group sought to provide a rapid response, but always in alignment with local partners, which allowed real needs to be identified, promoting various initiatives on a global level that include the involvement of volunteers, who play a fundamental role in this response.

Integrated Annual Report 2022 Performance Sustainability 164 A2E Fund| Koolboks “Man wey naked no dey put hand for pocket” is a saying in Nigerian pidgin, a Creole language based on English and spoken as a lingua franca throughout Nigeria. Loosely translated, the expression means something like "You can't do anything without certain conditions." The motto for the launch of Fundo A2E (A2E Fund) as financial support for one of the projects selected in the third edition, Koolboks, a sustainable model for the financing of off-grid solar refrigerators for women fish traders. The typical fish trader at the market in Ijora, Nigeria, loses 30% of their merchandise every day due to the lack of reliable and affordable refrigeration. Because the power grid is unreliable, traders complement it with diesel generators, which are environmentally harmful and expensive, and they need to spend around $4 on fuel every two days to run the generator. Solar refrigeration is a potential solution which would guarantee the fish traders access to continuous refrigeration; however, initial costs are prohibitive. Koolboks technology creates ice compartments in the refrigerator cabinets so that during the day, when the sun is out, ice is made in the compartments. At night, the energy inside transfers to the ice, maintaining the temperature within the cabinet until the next day, when the sun comes out again. Thanks to this technology, the cost of having a solar refrigerator off the grid has dropped by about 40%. This solution is capable of generating continuous cooling for up to four days, even in the absence of power and with limited sunlight. Alhaja Boluwatife is a 53-year-old woman owner of a restaurant business inherited from her mother. With 20 years of experience, she was initially sceptical about the efficiency of a solar refrigerator: "Let me see how it works with my friend, Alhaja Aderinoye. I just bought a Honda generator for 550,000 nairas, but the fuel consumption is 5,000 nairas a day. This lasted from 6am until 3pm”. Two weeks later, with a positive review from her friend, Alhaja Boluwatife bought a 538 Litre Out. In addition to conserving fresh fish and selling cold drinks, the trader could now also sell ice, getting an extra income. In 2022, Fundo A2E supported the setting up of this project with 66.000 euros to supply solar refrigerators with 15 kWp of installed power, which impacted 144 direct beneficiaries, 150 indirect, and created 22 new jobs. It was also put to bet the recruitment and training of sales agents to support new business as well as capacity-building, training for equipment maintenance, certification and partnership with more than 60 direct sales agents and installers.

Integrated Annual Report 2022 Financial Statements and Notes 229 Conflict situation and geopolitical instability in Eastern Europe - Macroeconomic, Regulatory, Operational, Accounting Impact and relationship with Stakeholders On 24 February 2022, a military conflict was initiated in Ukraine with the invasion of its territory by the Russian troops which has resulted in a humanitarian crisis. Direct and indirect victims, and a significant number of refugees and displaced citizens (UN estimate of over 14 million people by end of December 2022) have been caused by the attacks to Ukrainian localities with several repercussions on the energy, commodities, intermediate goods, customer and service markets. This note identifies actual and potential business, financial, operational, accounting and strategic impacts. Given its geopolitical positioning, the conflict has particular relevance to the continuity of EDP Group's business in Europe, and for possibly more attenuated spill-overs for the operations in North America, Latin America and Asia. The magnitude of geopolitical tensions remains high, with relevant impacts arising from this crisis continuing to be felt, the worsening and/or prolonging of this conflict may increase an even greater increase in risk and negative impacts for EDP Group’s business. Impact on energy markets – energy crisis The prices of energy markets, particularly in Europe, rose to historically high levels in the 2nd half of 2021. The military conflict has further weakened energy markets and led to a larger sustained increase in energy prices in Europe, since Russia is one the main exporters of natural gas. Taking into account the introduction of regulatory measures to contain the price of gas and electricity all over Europe and, in particular, in Iberia, the pool price has stabilised. The main impacts/risks in terms of energy markets are: ● Prices of commodities: the sanctions and economic boycott of Russia, in an attempt to stop the aggression against Ukraine, have led to a limitation in the supply of natural gas, and an increase in demand from other markets (e.g., US’s LNG market), putting high pressure on prices of raw materials and, consequently, in the final price of energy; and ● Energy dependence/availability of resources/increase in economic protectionism: European energy reliance on Russia has also forced a reflection on viable alternatives to ensure energy independence, reinforcing the problem already felt at various levels (economic, political and now energetic) of regionalization/clustering – in opposition to globalization. This phenomenon consists in the approximation and dialogue with countries/neighbouring regions with common principles and goals, and an increase in protectionism in relation to other countries, operating autonomously in relation to the rest of the world. EDP continues to take a cautious approach, seeking to undertake a balanced integrated position in energy (especially in Iberia, where it has a Generation and Supply business), and closely monitoring the evolution of the markets. In terms of gas supply, EDP does not have any supply contract in place with Russia and is relatively more protected than other European peers from potential disruptions in the supply chains. The energy transition is also seen as a measure to increase the resilience and energetic independence of the markets, increasing the renewable share in the energy portfolio, reducing dependence on gas supply, with EDP being a player with a leadership role in this area. Regulatory impact In a context of economic uncertainty and energy crisis, the way in which international and governmental institutions in each country accommodate the impacts and try to limit economic consequences for economic agents was object of analysis and discussion. Several measures with significant impact have already been adopted, while others remain under analysis. In particular, to contain energy prices increase, regulatory mechanisms were created in Portugal and Spain by introducing a cap on the value considered for gas, as an electricity production factor (approved on 8 June, with effective date from 15 June 2022 to 31 May 2023). This mechanism implies the payment of compensation amounts to the electricity generators by consumers who will have benefited from the effects of the mechanism. Additionally, several packages of measures leading to energy savings were approved in several European countries, namely Portugal and Spain. Other regulatory mechanisms with an impact on EDP's business were also applied, namely clawback to inframarginal generation in specific countries (eg Spain, Romania). In Portugal, in addition to the partial reduction of the VAT rate applicable to electricity, the constitution of a strategic water reserve was also approved, which aims to ensure that the storage levels of 15 hydro power plants reach more comfortable values. Other mechanisms are being discussed at European level, namely the definition of a maximum cap on revenues from inframarginal power plants, a solidarity contribution tax on the oil & gas and coal sector, intervention in retail prices and liquidity guarantee mechanisms (collateral). Noteworthy is the recent approval of a European Regulation, which contains several of the measures mentioned above and which gives States members some discretion in their adoption or in the adoption of measures with a similar effect. 

Integrated Annual Report 2022 Financial Statements and Notes 230 In regulatory terms, the main risks identified are: ● Possible increase in sectorial charges or taxes on energy companies: creation/increase of additional fees and taxes to bridge the gap between energy production and sale prices; and ● Change in market structure: possible changes in market structure (e.g., introduction of a cap on the price of electricity, or decoupling of gas). EDP has been closely monitoring the developments on this topic, positioning itself in the best possible way in the face of the challenges brought about by the aforementioned changes. Financial impact In addition to energy markets, financial market continues to experience times of huge instability and volatility, with a significant negative impact. The main financial risks identified are: ● Inflation: current constraints are not only limited to gas sourcing, with impact in the energy sector, but also to essential raw materials in sectors such as agriculture, transport, among others, leading to a general increase in prices. EDP Group’s business has a high degree of indexation, directly or indirectly, of its revenues to inflation, mitigating this risk; ● Growing interest rates: pressure on interest rates leads to increases in financing costs related with floating rate debt and new fixed rate debt. EDP has focused on increasing the duration of its fixed debt during the year 2022 and on pre-hedging future financing; ● Counterparty default: the huge increase of prices in the energy market raised the exposure to counterparties in long positions. Additionally, the prolongation of the conflict and the increase of sanctions against Russia and the penalizations of several institutions may lead to an increase in the default risk of some counterparties; and ● Liquidity: extremely high initial margins in organized markets due to very high prices and volatility, giving rise to significant cash variations and an increase in collateral requests. EDP has been closely monitoring the evolution of the financial markets and the financial situation of its counterparties, seeking to mitigate exposure to potential financial risks, with a cautious approach in terms of the interest rate combination with a high percentage of fixed rate, a careful choice of its main counterparties favouring high ratings and high levels of liquidity (cash and available credit lines). Operational impact The Russia-Ukraine conflict has been resulted in several operational impacts, direct and indirect, either due to the presence of EDP operations in border regions with Ukraine, or due to the dependence on products and raw materials coming from the region. Several risks with operational impacts were identified, namely: ● Physical assets and operations: the proximity of physical generation assets (EDP Renováveis) to the border with Ukraine, namely in Poland, Romania and Hungary, countries with greater risk of suffering damage in the event of a geographic expansion of the military conflict, is noteworthy. There may also be additional constraints, including increases in the maintenance costs of assets due to a rise in the price of resources and raw materials, and/or due to the unavailability of labour coming from the affected countries; ● People's safety: the existence of generation infrastructures close to the conflict region also implies the presence of EDP teams and subcontracted teams, which, even though these are not permanently in these facilities, may expose them to a higher level of risk with the evolution of the conflict; ● Cybersecurity: there continues to be a high number of cyberattacks worldwide, with an increase level of sophistication and a potential impact for EDP, directly or indirectly (for example, through providers of critical IT and OT services), which continues to motivate a reinforcement of safety monitoring and the adoption of complementary measures by EDP; ● Supply chain: there continues to be no relevant direct exposure of EDP to countries in conflict or sanctioned, however, there may be indirect dependence through EDP suppliers of products and raw materials (fuels, but also other resources such as copper, aluminium, nickel, among others), from Russia or Ukraine, or whose transport route crosses/passes in the area of the conflict zone, raising the possibility that the supply chain may be subject to disruptions by different causes and with variable duration. There is also an increase in the costs associated with these goods, both in terms of production, given the shortage of some raw materials, and in terms of transport; and ● Compliance: the application of sanctions to Russia by different countries and organizations, including the EU, continues to require internal monitoring in order to reduce the risk of EDP's non-compliance with such sanctions and manage any previously established partnerships. EDP continues to reinforce the security and contingency mechanisms associated with its employees, as well as its operation and critical assets, including but not limited to the active monitoring of the evolution of the different risk factors identified. Additionally, EDP established local plans and strategies to answer to the possible geographic spread of the conflict, in order to protect people and assets. 

Integrated Annual Report 2022 Financial Statements and Notes 231 EDP's operational and investment activities are reliant on local and global supply chains, with an active management of critical supplies being carried out to minimize potential impacts of disruptions in these chains. Accounting impact EDP Group has not applied any different classifications from those normally used in its Consolidated Income Statement, as a result of the conflict above mentioned. To assess possible accounting impacts, the Group reassessed the estimates it considers relevant and which may have been impacted by this fact, in particular those arising from the aforementioned increase in inflation rates and interest rates. The impacts recognised at 31 December 2022, as well as the respective sensitivity analyses, are described throughout the notes to financial statements, namely regarding the impairment tests of non-financial assets (see note 12), provisions for dismantling (see note 36) and employee benefits (see note 35). Strategic impact (macroeconomics and relationship with key stakeholders) Macroeconomic impact The current geopolitical crisis in Eastern Europe includes significant risks for the economy and society, with an associated level of uncertainty about the duration of the conflict and the economic impacts that will outcome. In global macroeconomic, impacts have been felt in terms of increased costs of raw materials, particularly regarding energetic and agricultural, as well as a greater probability of disruption in international supply chains. Additionally, beside causing the escalation of existing geopolitical tensions, contributing to global instability with still uncertain medium-long- term consequences, the proximity of the conflict to the borders of the EU also represents a challenge to the cohesion between the member states. Relationship with stakeholders Since the first moment, EDP Group has assumed the commitment to safeguard the interests of its stakeholders and has been permanently following up the main developments of the military conflict and possible implications for all the stakeholders involved. This monitoring and intervention has been manifested at different levels, of which the following stand out: ● Employees: EDP has been reinforcing its internal communication, raising awareness of possible impacts arising from the conflict, as well as its positioning and measures adopted to manage such outcomes; ● Customers: EDP reinforced its concern with stabilizing energy prices, particularly in the free market, despite the high volatility of costs associated with fuels and other raw materials; ● Communities: EDP has launched a humanitarian aid campaign with its employees, and has combined efforts with institutions presented locally in order to support the most disadvantaged and vulnerable; and ● Shareholders: the Executive Board of Directors has been working closely with the General and Supervisory Board, in order to act in the most suitable manner, protecting the interests of its shareholders. 

Integrated Annual Report 2022 Financial Statements and Notes 232 1\. Economic activity of EDP Group EDP - Energias de Portugal, S.A. (hereinafter referred to as EDP), currently with head office in Lisbon, Avenida 24 de Julho 12 and with its shares listed on the Euronext Lisbon stock exchange, results from the transformation of Electricidade de Portugal, E.P., incorporated in 1976 following the nationalization and consequent merger of the main companies in the electricity sector in Portugal. During 1994, as established by Decree- laws 7/91 and 131/94, the EDP Group (EDP Group or Group) was set up following the split of EDP, which led to a number of directly or indirectly wholly owned subsidiaries of EDP. The Group’s businesses are currently focused on the generation, transmission, distribution and supply of electricity and supply of gas. Additionally, the Group also operates in related areas such as engineering, laboratory tests, professional training, energy services and property management. EDP Group operates essentially in the European (Portugal, Spain, France, Poland, Romania, Italy, Belgium, United Kingdom and Greece), American (Brazil, Colombia and North America) and Southeast Asia energy sectors. 2\. Accounting policies a) Basis of presentation The accompanying condensed consolidated and company financial statements of EDP - Energias de Portugal, S.A. reflect the results of the company's operations and its subsidiaries (EDP Group or Group) and the Group's interest in its joint ventures and associated companies, for the periods ended on 31 December 2022 and 2021 and EDP S.A.'s Executive Board of Directors approved them on 01 March 2023. The financial statements are presented in thousand Euros, rounded to the nearest thousand. In accordance with Regulation (EC) 1606/2002 of the European Council and Parliament, of 19 July 2002, as transposed into Portuguese legislation through Decree-law 35/2005 of 17 February 2005, with changes updated by the Decree-law 158/2009 of 13 July and Decree-law 98/2015 of 2 June, the company's financial statements and the Group's consolidated financial statements are prepared in accordance with International Financial Reporting Standards (IFRS), as endorsed by the European Union (E.U). IFRS comprise accounting standards issued by the International Accounting Standards Board (IASB) as well as interpretations issued by the International Financial Reporting Interpretations Committee (IFRIC) and their predecessor bodies. The EDP Group's consolidated and company financial statements for the years ended 31 December 2022 and 2021 were prepared in accordance with IFRS as adopted by the E.U. and effective since 1 January 2022. The accounting policies used by the Group in preparing the consolidated financial statements described in this note were adopted in accordance. The new standards and interpretations recently issued but not yet effective and that the Group has not yet applied on its consolidated financial statements, are detailed in note 3. The financial statements have been prepared on a going concern basis and under the historical cost convention, modified by the application of the fair value accounting to derivative financial instruments, financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income. Assets and liabilities that are hedged under hedge accounting are stated at fair value in respect of the hedged risk. Non-current assets and disposal groups held for sale are stated at the lower of carrying amount and fair value less costs to sell. Liabilities for defined benefit plans are recognised at the present value of the obligation net of plan assets fair value. In accordance with IFRS 3 - Business Combinations, if the initial purchase price allocation of assets, liabilities and contingent liabilities acquired is identified as provisional, in the subsequent 12 months after the business combination transaction, the legal acquirer should make the final allocation of the purchase price related to the fair value of the assets, liabilities and contingent liabilities acquired. These adjustments with impact on the amount of goodwill determined and booked in previous periods, originate a restatement of the comparative information, which is reflected on the statement of financial position, with effect from the date of the business combination transaction. Change in the presentation of Social Tariff costs Within the scope of the regulatory changes verified in Spain in 2022, the Group has reassessed the accounting of the costs related to Social Tariff in its income statement. Due to the nature of these costs, it has been concluded that they should be accounted for as "Other expenses". In this sense, the costs related to social tariff incurred in 2021 were reclassified from the “Cost of energy sales and other” to “Other expenses” (amounting to 72,271 thousand Euros at 31 December 2021). 

Integrated Annual Report 2022 Financial Statements and Notes 233 Change in the presentation of green certificates - Inventories During 2022, the Group has reviewed its accounting policy relating to Green Certificates and RECs, based on decisions issued by the European Securities and Markets Authority (ESMA) regarding transactions of a similar nature. According to the analysis carried out, it has been concluded that these Certificates are considered government support in accordance with IAS 20 that must be accounted for under the caption “Revenues and cost of Energy Sales and Services and Other”, with unsold certificates being recognised as inventories in accordance with IAS 2. In this sense, the Group proceeded to reclassify the amounts recognised under "Intangible assets" to "Inventories" (amounting to 157,532 thousand Euros at 31 December 2021 and 148,668 thousand Euros at 1 January 2021), since it has been concluded that this is the most appropriate presentation and the one that better reflects the nature of these assets, maintaining all other recognition and measurement criteria unchanged. The preparation of financial statements in conformity with IFRS requires the Executive Board of Directors to make judgments, estimates and assumptions that affect the application of the accounting policies and the reported amounts of assets, liabilities, income and expenses. The estimates and related assumptions are based on historical experience and other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments regarding the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. The issues involving a higher degree of judgment or complexity, or where assumptions and estimates are considered to be significant, are presented in note 4 - Critical accounting estimates and judgments in preparing the financial statements. Accounting policies have been applied consistently by all Group companies and in all periods presented in the consolidated and company financial statements. b) Basis of consolidation The accompanying consolidated financial statements reflect the assets, liabilities and results of EDP, S.A. and its subsidiaries (Group or EDP Group) and the equity and results attributable to the Group, through the investments in associates and jointly controlled entities. Controlled entities Investments in subsidiaries where the EDP Group has control are fully consolidated from the date the Group assumes control over their financial and operating activities and/or over their assets and liabilities until the moment that control ceases to exist. An investor controls an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee, independently of the percentage of voting rights held. Accumulated losses are attributed to non-controlling interests in the corresponding proportions held, implying that the Group can recognise negative non-controlling interests. On a step acquisition process resulting in the acquisition of control the revaluation of any interest previously held is booked against the income statement when goodwill is calculated. On a partial disposal resulting in loss of control over a subsidiary, any participation retained is revalued at market value on the sale date and the gain or loss resulting from this revaluation is booked against the income statement, as well as any gain or loss resulting from the disposal. Jointly controlled entities EDP Group classifies an arrangement as a joint arrangement when the jointly control is contractually established. Joint control exists only when decisions about the relevant activities require the unanimous consent of the parties that collectively control the arrangement. After determining the existence of joint control, the Group classifies joint arrangements into two types - joint operation or joint venture. A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement (i.e. joint operators) have rights to the assets and obligations for the liabilities relating to the arrangement, so the assets and liabilities (and related revenues and expenses) in relation to its interest in the arrangement are recognised and measured in accordance with relevant IFRS applicable. A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement (i.e. joint ventures) have rights to the net assets of the arrangement, so these investments are included in the consolidated financial statements under the equity method. The consolidated financial statements include the Group's attributable share of total reserves and profits or losses of joint ventures, included under the equity method. When the Group’s share of losses exceeds its interest in a joint venture, its carrying amount is reduced to zero and recognition of further losses is discontinued, except to the extent that the Group has a legal or contractual obligation to cover such losses on behalf of that entity. 

Integrated Annual Report 2022 Financial Statements and Notes 234 Entities over which the Group has significant influence Investments in associates are included in the consolidated financial statements under the equity method from the date the Group acquires significant influence to the date it ceases. Associates are entities over which the Group has significant influence, but not control, over its financial and operating policies. The existence of significant influence by the Group is usually evidenced by one or more of the following: \- Representation on the Executive Board of Directors or equivalent governing body of the investee; \- Participation in policy-making processes, including participation in decisions about dividends or other distributions; \- Existence of material transactions between the Group and the investee; \- Interchange of managerial personnel; and \- Provision of essential technical information. The consolidated financial statements include the Group's attributable share of total reserves and profits or losses of associates, included under the equity method. When the Group’s share of losses exceeds its interest in an associate, its carrying amount is reduced to zero and recognition of further losses is discontinued, except to the extent that the Group has a legal or constructive obligation to cover such losses on behalf of the associate. Accounting for investments in subsidiaries, joint ventures and associates in the company's financial statements Investments in subsidiaries, joint ventures and associates not classified as held for sale or not included in a disposal group which is classified as held for sale are accounted for at cost in the company's financial statements, and are subject to periodic impairment tests, whenever indication exists that certain financial investment may be impaired. Goodwill Following the transition to International Financial Reporting Standards (IFRS) on 1 January 2004 and as permitted under IFRS 1 - First-time Adoption of International Financial Reporting Standards, the EDP Group decided to maintain the goodwill resulting from business combinations that occurred prior to the transition date, calculated in accordance with the Group's previous accounting policies. Costs directly attributable to the acquisition of a subsidiary are booked directly in the income statement. As from the transition date to IFRS, total positive goodwill arising from acquisitions is recognised as an asset carried at acquisition cost and is not subject to amortisation. Goodwill arising on the acquisition of subsidiaries, joint ventures and associates is defined as the difference between the cost of acquisition and the corresponding share of the fair value of the net assets acquired. The EDP Group has the possibility to book non-controlling interests at fair value or at cost, implying that the full amount of goodwill can be booked in the financial statements, including the portion attributable to the non-controlling interests, against non-controlling interests, if the first option is chosen. Goodwill arising on the acquisition of subsidiaries, joint ventures and associates is defined as the difference between the cost of acquisition and the total or corresponding share of the fair value of the net assets acquired, depending on the option taken. Negative goodwill arising on an acquisition is recognised directly in the income statement in the period when the business combination occurs. The recoverable amount of the goodwill is assessed annually, regardless of the existence of any impairment triggers. Impairment losses are recognised in the income statement. The recoverable amount is determined based on the value in use of the assets, calculated using valuation methodologies supported by discounted cash flow techniques, considering market conditions, the time value of money and the business risks. Goodwill is not adjustable due to changes in the initial estimate of the contingent purchase price and the difference is booked in the income statement. Purchases of non-controlling interests and dilution In acquisitions (dilutions not resulting in a loss of control) of non-controlling interests, the difference between the fair value of the non-controlling interests acquired and the consideration paid, is accounted against reserves. The acquisitions of non-controlling interests through written put options related with investments in subsidiaries held by non-controlling interests, are recorded as a liability for the fair value of the amount payable, against non-controlling interests. The fair value of the liability is determined based on the contractual price which may be fixed or variable. In case of a variable price, the changes in the liability are recognised against the income statement as well as the effect of the financial discount of the liability (unwinding). 

Integrated Annual Report 2022 Financial Statements and Notes 235 Investments in foreign operations The financial statements of the foreign subsidiaries, joint ventures and associates of the Group are prepared using their functional currency, defined as the currency of the primary economic environment in which they operate. In the consolidation process, the assets and liabilities of foreign subsidiaries are translated into Euros at the official exchange rate at the balance sheet date. Regarding the investments in foreign operations that are consolidated using the full consolidation method and equity method, the exchange differences between the amount of equity expressed in Euros at the beginning of the period and the amount translated at the official exchange rates at the end of the period, on a consolidated basis, are booked against reserves. Foreign currency goodwill arising on the acquisition of these investments is remeasured at the official exchange rate at the balance sheet date directly against reserves. The income and expenses of foreign subsidiaries are translated into Euros at the approximate exchange rates at the dates of the transactions. Exchange differences from the translation into Euros of the net profit for the period, arising from the differences between the rates used in the income statement and those prevailing at the balance sheet date are recognised in reserves. On disposal of a foreign subsidiary, the related exchange differences previously recognised in reserves, are accounted for in the income statement. Balances and transactions eliminated on consolidation Inter-company balances and transactions, including any unrealised gains and losses on transactions between Group companies, are eliminated in preparing the consolidated financial statements. Unrealised gains and losses arising on transactions with associates and jointly controlled entities are eliminated to the extent of the Group's interest in those entities. Business combinations achieved in stages In a business combination achieved in stages, on the date of obtaining control, the excess of the aggregate of (i) the consideration transferred; (ii) the amount of any non-controlling interest recognised in the acquiree; and (iii) the fair value of the previously held equity interest in the acquired business; over the net of amounts of the identifiable assets acquired and liabilities assumed, is recognised as goodwill. If applicable, the negative difference, after evaluating the consideration transferred, of the amount of any non-controlling interest recognised in the acquiree and the fair value of the previously held equity interest in the acquired business, over the net value of the identifiable assets acquired and liabilities assumed, is recognised in the income statement. The Group recognises the difference between the fair value of the previously held equity interest in the acquired business and the carrying value in consolidated results in Other income. Additionally, the Group reclassifies the deferred amounts in other comprehensive income relating to the previously held equity interest to the income statement or consolidated reserves, according to their nature. c) Foreign currency transactions Foreign currency transactions are translated at the exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currency are translated into Euros at the exchange rates at the balance sheet date. These exchange differences arising on translation are recognised in the income statement as financial results. Foreign currency non-monetary assets and liabilities accounted for at historical cost are translated using the exchange rates at the dates of the transactions. Foreign currency non-monetary assets and liabilities stated at fair value are translated into Euros at the exchange rates at the dates the fair value was determined. d) Derivative financial instruments and hedge accounting Derivative financial instruments are recognised on the trade date at fair value. Subsequently, the fair value of derivative financial instruments is remeasured on a regular basis, being the gains or losses on re-measurement recognised directly in the income statement, except for derivatives designated as cash flow hedging instruments. Recognition, in the income statement, of the resulting gains and losses on re-measurement of hedging derivatives depends on the hedge model used. The fair value of derivative financial instruments corresponds to their market value, if available, or to quotes indicated by external entities through the use of valuation techniques accepted by the market, which are compared in each date of report to fair values available in common financial information platforms, namely Bloomberg and Reuters. 

Integrated Annual Report 2022 Financial Statements and Notes 236 Hedge accounting The Group uses financial instruments to hedge interest rate risk, exchange rate risk and price risk resulting from its operational and financing activities. Derivatives not qualified for hedge accounting under IFRS 9 are accounted for as trading instruments. Hedging derivatives are recorded at fair value, being the gains and losses recognised in accordance with the hedge accounting model applied by the Group. Hedge relationship exists when: (i) The hedging relationship consists only of hedging instruments and hedged items that are eligible as per determined in IFRS 9; (ii) At the inception of the hedge there is formal documentation of the hedging relationship and the Group's risk management objective and strategy for the hedge; (iii) There is an economic relationship between the hedged item and the hedging instrument; (iv) The effect of credit risk does not dominate the value changes that result from that economic relationship; and (v) The hedge ratio of the hedging relationship is the same as that resulting from the quantity of the hedged item that the entity actually hedges and the quantity of the hedging instrument that the entity actually uses to hedge that quantity of hedged item. Fair value hedge Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in the income statement, together with any changes in the fair value of the hedged assets and liabilities or group of hedged assets and liabilities that are attributable to the hedged risk. For cross currency interest rate swaps, the currency basis spread is excluded from the hedge designation, but considered as a hedging cost in other comprehensive income, in cost of hedging reserve. When the hedging relationship ceases to comply with the requirements for hedge accounting, the accumulated gains or losses concerning the fair value of the risk being hedged are amortised over the residual period to maturity of the hedged item. Cash flow hedge Changes in the fair value of derivatives qualified as cash flow hedges are recognised in reserves. The cumulative gains or losses recognised in reserves are reclassified to the income statement when the hedged item affects the income statement. When a hedging relation of a future transaction is discontinued, if the transaction is still expected to take place, the changes in the fair value of derivative recognised in reserves remain recognised in reserves until the future hedged transaction occurs. When the future transaction is no longer expected to occur, the cumulative gains or losses recognised in reserves are recorded immediately in the income statement. Net investment hedge The net investment hedge model is applied on a consolidated basis to investments in subsidiaries in foreign currencies. This model allows that the exchange differences recognised in the currency translation reserve to be offset by the foreign exchange differences in foreign currency loans or currency derivatives contracted, recognised in Currency translation reserve - Net investment hedge. For cross currency interest rate swaps, the cross currency basis spread and forward points are not designated into the hedge relationship, but deferred as a hedging cost in other comprehensive income, in Currency translation reserve - Net investment hedge - Cost of hedging, and recognized in profit or loss over the period of the hedge. The ineffective portion of the hedging relationship is recognised in the income statement. The accumulated foreign exchange gains and losses regarding the net investment and the related hedging instrument recognised in equity are transferred to the income statement when the foreign currency subsidiary is sold, as part of the gain or loss resulting from the disposal. Effectiveness For a hedge relationship to be classified as such, in accordance with IFRS 9, its effectiveness must be demonstrated. Therefore, the Group performs prospective tests at the inception date and at each balance sheet date, in order to demonstrate its effectiveness, showing that any adjustments to the fair value of the hedged item attributable to the risk being hedged are offset by adjustments to the fair value of the hedging instrument. Any ineffectiveness is recognised in the income statement when it occurs. e) Debtors and Other assets The financial assets are classified based on the business model for managing the financial assets ("business model test") and their contractual cash flow characteristics ("SPPI test"). EDP Group classifies its financial assets, at the initial recognition, in accordance with the aforementioned requirements introduced by IFRS 9, on the following categories: 

Integrated Annual Report 2022 Financial Statements and Notes 237 Financial assets at amortised cost A financial asset is measured at amortised cost if: (i) it is held within a business model whose objective is to hold assets in order to collect its contractual cash flows; and (ii) the contractual cash flows represent solely payments of principal and interest. Financial assets included within this category are initially recognised at fair value and subsequently measured at amortised cost. Any gain or loss arising on derecognition is recognised directly in profit or loss and presented in other gains/(losses) together with foreign exchange gains and losses. Impairment losses are presented as separate line item in the statement of profit or loss. Loans and trade receivables are generally held to collect contractual cash flows and are expected to give rise to cash flows representing solely payments of principal and interest, thus they meet the criteria for amortised cost measurement under IFRS 9. Financial assets measured at fair value through other comprehensive income (FVOCI) A financial asset is measured at fair value through other comprehensive income if (i) the objective of the business model is achieved by both collecting contractual cash flows and selling financial assets; and (ii) the asset’s contractual cash flows represent solely payments of principal and interest. Financial assets included within this category are initially recognised and subsequently measured at fair value, with the changes in the carrying amount booked in other comprehensive income, except for the recognition of impairment gains or losses, interest revenue and foreign exchange gains and losses, which are recognised in profit and loss. When the financial asset is derecognised, the cumulative gain or loss previously recognised in other comprehensive income is reclassified to profit or loss. Financial assets measured at fair value through profit or loss (FVTPL) Financial assets that do not meet the criteria to be classified under the previously referred categories, are classified at fair value through profit or loss, deemed to be a residual category under IFRS 9. Regardless of the business model assessment, EDP Group can elect to classify a financial asset at fair value through profit or loss if doing so reduces or eliminates a measurement or recognition inconsistency (“accounting mismatch”). Changes in the business model assessment over time Financial assets are not reclassified subsequent to their initial recognition. However, if the Company changes its business model for managing financial assets, it will classify newly originated or newly purchased financial assets under the new business model, but will keep the classification of existing assets under the previous business model. Recognition and derecognition of financial assets Purchases and sales of financial assets are recognised on the trade date, which is the date on which the Group commits to purchase or sell these financial assets. Financial assets are derecognised when: (i) the Group contractual rights to receive their future cash flows have expired, (ii) the Group has transferred substantially the risks and rewards of ownership, or (iii) although retaining some, but not substantially all the risks and rewards of ownership, the Group has transferred control over the assets. Impairment EDP Group recognises an impairment loss based on the Expected Credit Loss (ECL) model, before the objective evidence of a loss event from past actions. This model is the basis for the recognition of impairment losses on held financial assets that are measured at amortised cost or at fair value through other comprehensive income (which includes cash and cash equivalents, trade receivables, loans and debt securities). The impairment methodology applied depends on whether there has been a significant increase in credit risk since initial recognition. If the credit risk on a financial asset does not increase significantly since its initial recognition, EDP Group measures the loss allowance for that financial asset at an amount equal to 12-month expected credit losses. If the credit risk increases significantly since its initial recognition, EDP Group measures the loss allowance for that financial asset at an amount equal to lifetime expected credit losses. Regardless of the above, a significant increase in credit risk is presumed if there is an objective evidence that the financial asset is impaired, including if there is observable data that comes to the attention of the holder of the asset about the following loss events, among others: significant financial difficulty of the issuer or obligor; restructuring of an amount due to the Group in terms that it would not consider otherwise; a breach of contract, such as a default or delinquency in interest or principal payments; or it becoming probable that the borrower will enter bankruptcy or other financial reorganisation. 

Integrated Annual Report 2022 Financial Statements and Notes 238 As soon as the loss event occurs in terms of IFRS 9, the impairment allowance would be allocated directly to financial asset affected, that is, the asset’s carrying amount is reduced and the amount of the loss is recognised in profit or loss. If, in a subsequent period, the amount of the impairment loss decreases, the previously recognised impairment loss is reversed in profit or loss, if the decrease can be related objectively to an event occurring after the impairment loss was recognised. Trade receivables, including contract assets EDP Group applies the simplified approach and records lifetime expected losses on all trade receivables and contract assets, including those with a significant financing component. The estimated ECL are calculated based on actual credit loss experience over a period that, per business and type of customers, is considered statistically relevant and representative of the specific characteristics of the underlying credit risk. When applicable, EDP Group estimated the ECL rates separately for corporates and individuals. Considering the particularities of each business, exposures are segmented based on common credit risk characteristics such as credit risk grade, geographic region and/or industry - for corporates; and type of product purchased - for individuals, as applicable. Actual credit loss experience is adjusted by scalar factors to reflect differences between economic conditions during the period over which historical data was collect, current conditions and EDP Group's view of economic conditions over the expected lives of the receivables. Other receivables and financial assets For receivable assets related to regulatory assets, loans, financial entities and State carried at amortised cost and FVOCI, EDP Group performs an analysis based on the general approach. On making its assessment, the company has to make assumptions about risk of default and expected loss rates, which requires judgement. The inputs used for risk assessment and for calculation of the loss allowances for financial assets includes: (i) credit ratings (as far as available) from external credit rating companies such as Standard and Poors, Moody’s and Fitch; (ii) significant changes in the expected performance and behaviour of the borrower, including changes in the payment status of borrowers in the Group and changes in the operating results of the borrower; (iii) public market data, namely on probabilities of default and loss given default expectations; and (iv) macroeconomic information (such as market interest rates or growth rates). Leases – Lessor perspective A lessor classifies each of its lease as either an operating lease or a finance lease. A lease is classified as a finance lease if it transfers substantially all the risks and rewards incidental to ownership of an underlying asset. A lease is classified as an operating lease if it does not transfer substantially all the risks and rewards incidental to ownership of an underlying asset. At the commencement date, a lessor recognises assets held under a finance lease in its statement of financial position and present them as a receivable at an amount equal to the net investment in the lease. A lessor recognises lease payments from operating leases as income on either a straight‐line basis or another systematic basis (if that basis is more representative of the pattern in which benefit from the use of the underlying asset is diminished). The assets subject to operating leases are presented in its statement of financial position according to the nature of the underlying asset. f) Trade payables and other liabilities An instrument is classified as a financial liability when there is a contractual obligation for the issuer to liquidate capital and/or interests, through delivering cash or other financial asset, regardless of its legal form. Financial liabilities are recognised at the issuance date (trade date): (i) initially at fair value less transaction costs; and (ii) subsequently at amortised cost, using the effective interest method. All financial liabilities are booked at amortised cost, with the exception of the financial liabilities hedged at fair value hedge, which are stated at fair value on risk component that is being hedged. Derecognition of financial liabilities EDP Group derecognises a financial liability (or a part of a financial liability) from its statement of financial position when, and only when, the obligation specified in the contract is discharged, cancelled or expired. An exchange between an existing borrower and lender of debt instruments with substantially different terms is accounted for as an extinguishment of the original financial liability and the recognition of a new financial liability. Similarly, a substantial modification of the terms of an existing financial liability, or a part of it, is accounted for as an extinguishment of the original financial liability and the recognition of a new financial liability. The difference between the carrying amount of a financial liability (or part of a financial liability) extinguished or transferred to another party and the consideration paid, including any non-cash assets transferred or liabilities assumed, is recognised in profit or loss. 

Integrated Annual Report 2022 Financial Statements and Notes 239 Initial measurement of the lease liabilities As provided by IFRS 16, the lease liabilities on the commencement date are measured by the Group based on the present value of the future payments of that lease contracts, discounted using EDP Group's incremental borrowing rate for each portfolio of leases identified. EDP Group determines the lease term as the non‐cancellable period of a lease, together with both: (i) periods covered by an option to extend the lease, if the lessee is reasonably certain to exercise that option; and (ii) periods covered by an option to terminate the lease, if the lessee is reasonably certain not to exercise that option. EDP Group applies the recognition exemption provided by IFRS 16 for the leases which lease term is 12 months or less, or that are for a low-value asset. After the commencement date, the lease liabilities are increased to reflect interest on the liability and reduced to reflect the lease payments made. Remeasurement of the lease liabilities EDP Group remeasures the lease liabilities, and adjusts the corresponding right-of-use assets, by discounting the revised lease payments, using an unchanged discount rate, if either: i) there is a change in future lease payments resulting from a change in an index or a rate used to determine those payments; or ii) there is a change in the amounts expected to be payable under a residual value guarantee. If there is a lease modification that do not qualifies to be accounted as a separate lease, EDP Group remeasures the lease liabilities and adjusts the corresponding right-of-use assets, by discounting the revised lease payments, using a revised discount rate at the effective date of the modification. The variable lease payments that do not depend in an index or a rate are not included in the measurement of the lease liabilities, nor the right-of- use asset. Those payments are recognised as cost in the period in which the event or condition that gives rise to the payments occurs. g) Equity instruments A financial instrument is classified as an equity instrument when there is no contractual obligation at settlement to deliver cash or other financial asset to another entity, regardless of its legal form, and there is a residual interest in the assets of an entity after deducting all its liabilities. Costs directly attributable to the issuance of equity instruments are recognised in equity, as a deduction to the amount issued. Amounts paid or received relating to sales or acquisitions of equity instruments are recognised in equity, net of transaction costs. Distributions related to equity instruments are deducted from equity, as dividends, when declared. Preference shares issued by the Group are considered as an equity instrument when there is no contractual obligation to redeem the shares and dividends are paid at the discretion of the Group. Preference shares issued by subsidiaries, classified as equity instruments and held by third parties, are recognised as non-controlling interests. Equity instruments at fair value EDP Group classifies the equity instruments that are held for trading at fair value to profit or loss. For all other equity instruments, management has the ability to make an irrevocable election on initial recognition, on an instrument-by-instrument basis, to present changes in fair value in other comprehensive income. If this election is made, all fair value changes, excluding dividends that are a return on investment, will be included in other comprehensive income. There is no recycling of amounts from other comprehensive income to profit and loss (for example, on sale of an equity investment) being, at that time, transferred to retained earnings. h) Property, plant and equipment Property, plant and equipment is stated at acquisition cost less accumulated depreciation and impairment losses. On transition to IFRS, on 1 January 2004, the Group decided to consider as deemed cost the revalued amount of Property, plant and equipment in accordance with the Group's previous accounting policy, which was comparable in general terms to the depreciated cost determined in accordance with IFRS. Subsequent costs are recognised as Property, plant and equipment only when it is probable that future economic benefits associated with the item will flow to the Group. Repair and maintenance costs are charged in the income statement as incurred, according to the accrual principle. 

Integrated Annual Report 2022 Financial Statements and Notes 240 The Group carries out impairment tests whenever events or circumstances may indicate that the book value of an asset exceeds its recoverable amount, being any impairment recognised in the income statement. The recoverable amount is the higher of fair value less costs to sell and value in use, the latter being calculated by the present value of the estimated future cash flows obtained from continued use of the asset and its sale at the end of its useful life. Land is not depreciated. Depreciation of tangible assets is calculated on a straight-line basis over their estimated useful lives, as follows: Buildings and other constructions 8 to 50 Plant and machinery: \- Hydroelectric generation 30 to 75 \- Thermoelectric generation 25 to 45 \- Renewable generation 30 to 35 \- Electricity distribution 10 to 40 \- Other plant and machinery 4 to 25 Transport equipment 4 to 25 Office equipment and tools 2 to 16 Other property, plant and equipment 3 to 50 According to IFRS, the estimate of the useful life of assets should be reviewed whenever a change in the expected economic benefits flowing from the assets occurs as well as when the technical use planned for the assets differs from previous estimates. Changes occurring in the depreciation charge for the year are accounted prospectively. Capitalisation of borrowing costs and other directly attributable costs Borrowing costs that are directly attributable to the acquisition or construction of assets are capitalised as part of the cost of these assets. A qualifying asset is an asset that needs a substantial period of time to be ready for its intended use or sale. The amount of interest costs eligible for capitalisation is determined by applying a capitalisation rate to the expenditures on those assets. The capitalisation rate corresponds to the weighted average of the borrowing costs applicable to the outstanding borrowings during the period. The capitalisation of borrowing costs begins when expenditure for the assets is being incurred, borrowing costs have been incurred and activities necessary to prepare all or part of the assets for their intended use or sale are in progress. Capitalisation ceases when substantially all the activities necessary to prepare the qualifying assets for their intended use or sale are completed. Other expenses directly attributable to the acquisition and construction of the assets, such as cost of consumed materials and personnel costs, are also capitalised as part of the cost of the assets. Investment government grants Investment government grants are initially booked as Trade payables and other liabilities from commercial activities - Non-Current only when there is reasonable certainty that the grant will be received and that the Group will fulfil the grant term conditions. Grants that compensate the Group for expenses incurred are booked in the income statement on a linear basis, on the same period in which the expenses are incurred. Grants that compensate the Group for the acquisition of assets are recognised in the income statement over the related assets useful life. Transfers of assets from customers Transfers of assets from customers concession arrangement and out of the scope of IFRIC 12, in accordance with IFRS 15, are related to payments of performance obligations fulfilled over the useful life of the underlying asset. Accordingly, when they are received from the customers, they are booked as liabilities instead of revenue. The assets are recognised by the estimated construction cost and are depreciated over their useful lives. The liabilities are recognised as revenue based on the corresponding useful life of the underlying asset. i) Intangible assets The Group's intangible assets are booked at acquisition cost less accumulated amortisation and impairment losses. The Group performs impairment tests whenever events or circumstances may indicate that the book value of the asset exceeds its recoverable amount, being any impairment recognised in the income statement. The recoverable amount is the higher of fair value less costs to sell and value in use, the latter being calculated by the present value of the estimated future cash flows obtained from continued use of the asset and its sale at the end of its useful life. Acquisition and development of software The costs of purchasing software and the costs incurred by the Group to implement it are capitalised and amortised on a straight-line basis over the expected useful life of the asset. Number of years 

Integrated Annual Report 2022 Financial Statements and Notes 241 Costs incurred by the Group directly related to the development of software, that are expected to generate economic benefits beyond one year, are recognised as intangible assets. Such costs include employee costs directly associated to the project and are amortised on a straight-line basis over its estimated useful life. Software maintenance costs are charged to the income statement when incurred. Concession rights on distribution of electricity The concession rights on distribution of electricity in Brazil are recorded as intangible assets and amortised on a straight-line basis over the concessions period, not exceeding 30 years. Concession rights to use the public hydric domain Portuguese concession rights to use the public hydric domain are booked as intangible assets and depreciated on a straight-line basis over the concession period, which does not exceed 74 years. EDP Group records as concession rights the financial compensations for the use of public domain assets, whenever these compensations are paid and for all the Group subsidiaries. The accounting policy related to intangible assets assigned to concessions in the scope of IFRIC 12 is described in z), Group concession activities. Concession rights on generation of electricity The concession rights on generation of electricity in Brazil are recorded as intangible assets and amortised on a straight-line basis over the concession period. Industrial property and other rights Industrial property and other rights are amortised on a straight-line basis over the estimated useful life of the assets, not exceeding 6 years. j) Right-of-use assets EDP Group presents the information related to lease contracts in the caption Right-of-use assets, in a separate line in the Statement of Financial Position. These assets are accounted for at cost less accumulated depreciation and impairment losses. The cost of these assets comprises the initial costs and the initial measurement of the lease liabilities, deducted from the prepaid amounts and any incentives received. Depreciation of right-of-use assets is calculated on a straight-line basis over their estimated useful lives, considering the lease contract terms. Remeasurement of right-of-use assets If EDP Group remeasures the lease liability (see f)), the corresponding right-of-use assets shall be adjusted accordingly. k) Investment property The Group classifies as investment property, property held for capital appreciation and/or for rental purposes. Investment property is recognised initially at acquisition or production cost, including directly attributable transaction costs, and is subsequently measured at cost less accumulated depreciation and any impairment losses. Subsequent expenditures on investment property are only added to the cost of the asset when it is probable that additional future economic benefits will arise when compared to initial recognition. Investment property is depreciated on a straight-line basis over the estimated useful life of the assets (between 8 and 50 years). l) Inventories Inventories are measured at the lower of acquisition cost and net realisable value. The cost of inventories includes purchases, conversion and other costs incurred in bringing the inventories to their present location and condition. The net realisable value is the estimated selling price in the ordinary course of business less the estimated selling costs. The cost of inventories is determined by using the weighted average cost method. CO2 Licenses held by the Group for trade purposes are booked as inventories and measured at fair value, at each balance sheet date, against the income statement. 

Integrated Annual Report 2022 Financial Statements and Notes 242 The green certificates are considered government support in accordance with IAS 20 that are accounted for under the caption "Revenues and cost of Energy Sales and Services and Other", with unsold certificates being recognised as inventories in accordance with IAS 2. m) Employee benefits Pensions Some EDP Group companies grant post-employment benefits to employees under defined benefit and defined contribution plans, namely pension plans that grant complementary retirement benefits for age and early retirement pensions. Defined benefit plans In Portugal, the defined benefit plan is assured by (i) a closed pension fund managed by an external entity, covering responsibilities with benefits that are complementary to those provided under the Social Security System (namely retirement and early retirement pensions); and (ii) by a complementary specific provision, recognised in the statement of financial position. Benefits are generally determined and assigned through the combination of one or more factors, such as age, years of service and the relevant base retribution (pensionable salary). The responsibilities for early retirement are not covered by the fund’s assets, being adequately provisioned through a specific provision. In Spain, the defined benefit plan is partially covered by insurance policies, and complemented by a specific provision, recognised at the balance sheet. Benefits are generally determined and assigned through the combination of one or more factors, such as age, years of service and the relevant base retribution (pensionable salary). In Brazil, EDP São Paulo and EDP Espírito Santo have defined benefit plans managed by a closed complementary welfare entity, external to EDP Group, covering responsibilities associated with retirement and early retirement pensions, according to factors such as age, years of service and the relevant base retribution. In the pension plans in Brazil, the surplus amount of the assets fund generally can not be reimbursed to the company, since there are very strict rules on the amount that can be recovered, therefore the asset amount to be recognised is greatly reduced. The Group’s pension liability for each plan is calculated by independent experts annually, for each plan, at the balance sheet date, using the projected unit credit method. The discount rate used in the calculation is determined based on market interest rates of high quality corporate bonds denominated in the currency in which the benefits will be paid and that have similar maturity to the related pension liability. Actuarial gains and losses presented in consolidated statement of comprehensive income comprise: (i) the actuarial gains and losses resulting from increases or decreases in the present value of the defined benefit obligation because of changes in actuarial assumptions and experience adjustments; (ii) the return on plan assets, excluding amounts included in net interest on the net defined benefit liability (asset); and (iii) any change in the effect of the asset ceiling, excluding amounts included in net interest on the net defined benefit liability (asset). The increase in past service costs arising from early retirements (retirements before the normal retirement age) or plan amendments is recognised in the income statement when incurred. The Group recognises as operational results, in the income statement, current and past service costs. Net interest on the net defined benefit liability (asset) is recognised in financial results. The assets of the plan comply with the recognition criteria established by IFRIC 14 - IAS 19 and the minimum funding requirements established by law or by contract. Defined contribution plans Some Group companies in Portugal, Spain and Brazil have defined contribution social benefit plans that complement those granted by the Social Security System, under which they pay an annual contribution to the plans, calculated in accordance with the rules established in each plan. These contributions represent a percentage of the fixed and variable remuneration of the employees included in this plan and are accounted for as cost for the period in which they are due. 

Integrated Annual Report 2022 Financial Statements and Notes 243 Other benefits granted - Defined Benefit Type Medical benefits Some EDP Group companies provide medical benefits under which employees and immediate eligible family members have favourable conditions in medical assistance and health care services, namely: \- Concerning EDP Group companies in Portugal, through the provision of medical assistance that is complementary to the one provided under the National Health System, provided using infrastructures owned and managed internally; \- Concerning EDP Group companies in Spain and Brazil, through the share of costs in eligible medical and health expenses, in an external agreed network. In Portugal, the medical benefit and death benefits plan is assured by (i) a closed fund managed by an external entity, created in December 2016, and (ii) a complementary specific provision, recognised in EDP Group company’s statement of financial position. In Spain, the medical care and death subsidy benefits plan is partially covered by insurance policies, and complemented by a specific provision, booked in EDP Group company’s statement of financial position. In Brazil, the liability is being covered by provisions booked in EDP Group company’s statement of financial position. Measurement and recognition of the medical benefits liabilities are similar to the defined benefit pension plans liabilities, explained above. Other benefits In addition, EDP Group grants other benefits, supporting charges arising from responsibilities for disability benefit’s complements, survival benefits, life insurance, antiquity and retirement benefits, power tariff discounts, among others. These responsibilities are fully covered by a provision. Benefits included in each Plan for Portugal and Brazil are detailed in EDP’s Collective Labor Agreement, published in the Labor Bulletin of 8 October 2014 and in the website of the Plan management entity Enerprev (www.enerprev.com.br), respectively. n) Provisions Provisions are recognised when: (i) the Group has a present legal, contractual or constructive obligation; (ii) it is probable that settlement will be required in the future; and (iii) a reliable estimate of the obligation can be made. Provisions for dismantling and decommissioning in electric power plants The Group accounts for provisions for dismantling and decommissioning of assets at the end of the assets’ useful life when there is a legal, contractual or constructive obligation. Therefore, such provisions have been booked for the electric power plants to cover the cost of restoring the location and land to their original condition. The provisions are calculated at the present amount of the expected future liability and are accounted for as part of the cost of the related property, plant and equipment being depreciated on a straight-line basis over the useful life of those assets. Decommissioning and dismantling provisions are remeasured on an annual basis based on the best estimate of the settlement amount. The unwinding of the discount at each balance sheet date is charged to the income statement. o) Recognition of revenue from contracts with customers EDP Group recognises revenue to depict the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for these goods or services, as provided in the 5 steps methodology introduced by IFRS 15, namely: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to performance obligations; and (v) recognise revenue when (or as) the entity satisfies a performance obligation. Revenue in EDP Group arises essentially from electricity generation and distribution and energy (electricity and gas) supply activities. Revenue related to the sale of energy and access tariffs to energy distribution network is measured at fair value of the consideration received or receivable, net of value added tax, rebates and discounts and after elimination of intra-group sales. 

Integrated Annual Report 2022 Financial Statements and Notes 244 Regarding the electricity generation, the transfer of control occurs when the energy is generated and injected into the transport/distribution grids. The electricity generated is sold under free market conditions or through the establishment of medium/long term power purchase agreements. The energy distribution is a regulated activity, which is remunerated through tariffs set by each country Regulatory Body (Entidade Reguladora dos Serviços Energéticos (ERSE) in Portugal, Comisión Nacional de Energía (CNE) in Spain and Agência Nacional de Energia Elétrica (ANEEL) in Brazil). In Portugal and Spain, revenue arises mainly from the sale of access tariffs, as well as from the recovery, from the commercialisation entities, of the costs related to the global management activity of the system. In Brazil, revenue results from the electricity sales to final consumers, in the regulated market, based on the tariffs determined by ANEEL, which are included the use of the distribution and transport system tariff, among other components. In Portugal and Brazil, these activities are subject to public service concession arrangements (see z)). Following the Directive 13/2018, of 15 December, on tariffs to be in force in 2019, and the premisses of IFRS 15, E-Redes – Distribuição de Eletricidade, S.A. acts as an agent in the purchase and sale of access to the transmission network (CVART) and therefore, as from this date onwards the associated amounts of costs and revenues are recorded at net value in the caption Revenues and cost of Energy Sales and Services and Other. The energy supply is carried out in regulated and non-regulated markets. In non-regulated market, revenue is recognised based on commercial agreements. In regulated market, revenue is recognised according to the tariffs determined by each country Regulatory Body. For contracts with customers in which the sale of energy and access tariffs are generally expected to be the only performance obligation, EDP Group recognises the revenue at a point in time when control of the asset is transferred to the customer, generally on delivery of the goods. Revenue recognition includes two components: (i) energy sales already invoiced, based on actual consumption readings and/or in estimated consumption based on the historical data of each consumer; and (ii) estimates of energy supplied and not yet invoiced (energy into energy meter). Differences between estimated and actual amounts are recorded in subsequent periods. For pluriannual contracts with customers for energy sales including a termination clause determined based on the estimated consumption and contractual set prices, revenue is recognised based on the "Input Method". Under this method, revenue is recognised according to the percentage of the contract execution and the corresponding contractual margin. The margin is reviewed annually, on a contract-by-contract basis, based on the updating of estimated energy supply volumes until the end of the contract. Additionally, it should be noted that, in energy distribution and supply activities, there is a tariff adjustment mechanism through which gains or losses of a certain year are recognised in the period to which they relate and recovered in the future years tariffs – Tariff Adjustments (see w)). EDP Group recognises the revenue related with services rendered over time in accordance with IFRS 15, given that the customer simultaneously receives and consumes the benefits provided by the Group. EDP Group also sells products and services as a part of an integrated commercial offer ("bundled"). In a bundled sale arrangement, the Group accounts the sale of each product and/or service separately if they are distinct, that is, if the product or service is separately identifiable in the context of the integrated offer and the customer benefits from it. The consideration paid is allocated between the goods or services separately identifiable based on their relative stand-alone selling prices. The stand-alone selling price is determined based on EDP Group price lists on goods or services sold separately or, if they are not listed, based on the market valuation approach. In what concerns variable transaction prices, EDP Group only recognises revenue when it is highly probable that there will not be any significant reversal of the recognised revenue, when it becomes certain. EDP Group considers the facts and circumstances when analysing the terms of each contract with customers, applying the requirements that determine the recognition and measurement of revenue in a harmonized manner, when considering contracts with the same characteristics and in similar circumstances. Contract liabilities As provided by IFRS 15, EDP Group presents a contract liability if the Group has an obligation to transfer goods or services to a customer for which the Group has received consideration (or an amount of consideration is due) from the customer. Contract assets As provided by IFRS 15, EDP Group presents a contract asset if the Group has a right to consideration that is conditional on something other than the passage of time. This is common when the Group has transferred goods or services to a customer usually before invoicing and the payment is due, excluding any amounts presented as a Trade receivables (unconditional rights to consideration). 

Integrated Annual Report 2022 Financial Statements and Notes 245 Incremental costs of obtaining a contract EDP Group establishes certain contracts with third parties for the promotion (sale) of energy and related services. These third parties act as sales agents and are paid through sales commissions. The Group recognises incremental costs of obtaining contracts with customers as an asset if the entity expects to recover these costs over the respective contracts. The costs incurred by an entity to obtain a contract with a customer are considered as incremental costs whenever it is clear that the entity would not incur these costs if the contract had not been obtained (for example, a sales commission). Therefore, EDP Group understands that the incremental costs to obtain a contract are eligible for capitalisation, accounting for a contract asset under the caption Debtors and other assets of commercial activities - Non-current. This asset shall be recognised in the income statement as amortisation, on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates. Considering the analysis carried out on the set of goods and services provided by the EDP Group to which these commissions relate, the useful life allocated to them varies between 6 and 8 years. p) Financial results Financial results include interest costs on borrowings, interest income on funds invested, dividend income, foreign exchange gains and losses, realised gains and losses, changes in fair value of derivative financial instruments related to financing activity classified by the Group, within IFRS 9, as held for trading and consequently measured at fair value through profit or loss, and changes in the fair value of hedged risks, when applicable. Interest is recognised in the income statement on an accrual basis. Dividend income is recognised on the date the right to receive is established. Considering the accounting model provided by IFRS 16, the financial results includes the interest expenses (unwinding) calculated on the lease liabilities. q) Income tax Income tax recognised in the income statement includes current and deferred tax. Income tax is recognised in the income statement except to the extent that it relates to items recognised directly in equity, in which case it is also recognised in equity. Deferred taxes arising from the revaluation of assets (debt instruments) measured at fair value through other comprehensive income and cash flow hedge derivatives recognised in equity are recognised in the income statement in the period the results that originated the deferred taxes are recognised. Current tax is the tax expected to be paid on the taxable income for the period, using tax rates enacted at the balance sheet date and any adjustment to tax payable in respect of previous years. Deferred taxes are calculated in accordance with the balance sheet liability method, considering temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax basis, using the tax rates enacted or substantively enacted at the balance sheet date for each jurisdiction and that are expected to be applied when the temporary differences are reversed. Deferred tax liabilities are recognised for all taxable temporary differences except for goodwill not deductible for tax purposes, differences arising on initial recognition of assets and liabilities that affect neither accounting nor taxable profit and differences relating to investments in subsidiaries, to the extent that these will probably not be reversed in the future. Deferred tax assets are recognised to the extent that it is probable that future taxable profits will be available to absorb deductible temporary differences for taxation purposes. The compensation between deferred tax assets and liabilities is performed at each subsidiary, and therefore the consolidated financial statements reflect in its assets the total of the deferred tax of subsidiaries that have deferred tax assets and in its liabilities the total of the deferred tax of subsidiaries that have deferred tax liabilities. The Group offsets, as established in IAS 12, the deferred tax assets and liabilities if, and only if: (i) the entity has a legally enforceable right to offset current tax assets against current tax liabilities; and (ii) the deferred tax assets and the deferred tax liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities which intend either to settle current tax liabilities and assets on a net basis, or to realise the assets and settle the liabilities simultaneously, in future periods in which deferred tax liabilities or assets are expected to be settled or recovered. When accounting for interest and penalties related to income taxes, EDP Group considers whether a particular amount payable or receivable is, in its nature, a taxable income and, if so, applies IAS 12 to this amount. Otherwise, IAS 37 is applied. 

Integrated Annual Report 2022 Financial Statements and Notes 246 Regarding the IFRIC 23 regarding IAS 12 – Income tax, when there is uncertainty over income tax treatments, EDP Group measures its current or deferred tax asset or liability applying the requirements in IAS 12. Additionally, the Group analyses all the pending litigations or disputes with tax authorities regarding income tax and records contingency and litigation provisions whenever necessary. r) Earnings per share Basic earnings per share are calculated by dividing the consolidated and the company net profit attributable to the equity holders of EDP, S.A. by the weighted average number of ordinary shares outstanding during the period, excluding the average number of shares held by the Group and by EDP, S.A., respectively. For the diluted earnings per share calculation, the weighted average number of ordinary shares outstanding is adjusted to consider conversion of all dilutive potential ordinary shares, such as convertible debt and stock options granted to employees. The dilution effect corresponds to a decrease in earnings per share resulting from the assumption that the convertible instruments are converted or the options granted are exercised. s) Share based payments The stock options remuneration program enables the Group's employees to acquire parent company shares. The exercise price of the options is calculated based on the listed price of the shares at the grant date. The fair value of the options granted, determined at the grant date, is recognised in the income statement against equity during the vesting period, based on their market value calculated at the grant date. In case the option is exercised, the Group acquires shares in the market to grant them to employees. Shareholders of EDP Brasil structured and implemented a Share based Compensation Policy, which began in June 2016. The referred policy comprises two types of programs to be granted to certain employees (incentive and retention programs), being the eligible beneficiaries and assignment requirements subject to the conditions established. t) Non-current assets held for sale and discontinued operations Non-current assets or groups of non-current assets held for sale (groups of assets and related liabilities that include at least one non-current asset) are classified as held for sale when their carrying amounts will be recovered mainly through sale, the assets or groups of assets are available for immediate sale and its sale is highly probable. The Group also classifies as non-current assets held for sale, non-current assets or groups of assets acquired exclusively for its subsequent resale, that are available for immediate sale and its sale is highly probable. Prior to their classification as held for sale, the measurement of all non-current assets and all assets and liabilities included in a disposal group, is adjusted in accordance with the applicable IFRS standards. Subsequently, these assets or disposal groups are measured at the lowest between their carrying amount and fair value less costs to sell. u) Cash and cash equivalents Cash and cash equivalents include balances with maturity of less than three months from the contract date, including cash and deposits in banks. This caption also includes other short-term, highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value, and specific demand deposits in relation to institutional partnerships that are funds required to be held in escrow sufficient to pay the remaining construction related costs of projects in institutional equity partnerships. On a company basis, EDP S.A. classifies as Cash and cash equivalents the current account balances with Group companies formalized through Cash Pooling Agreements (Group's financial system). v) Operating segments The Group presents the operating segments based on internal management information. In accordance with IFRS 8, an operating segment is a Group component: (i) that engages in business activities from which it may earn revenues and incur expenses; (ii) whose operating results are reviewed regularly by the entity's chief operating decision maker in order to make decisions about resources to be allocated to the segment and assess its performance; and (iii) for which discrete financial information is available. 

Integrated Annual Report 2022 Financial Statements and Notes 247 w) Tariff adjustments Classification and measurement of regulatory assets, which qualify as financial assets in EDP Group’s financial statements, is analysed based on the business model used in the management of the assets and the characteristics of the contractual cash flows (see e)). In this sense, deviations and tariff deficits exclusively recovered or returned through electricity and gas tariffs, applicable to customers in subsequent periods, are recognised at amortised cost. On the other hand, deviations or deficits that can be recovered, either through electricity rates (receipt of capital and interest) or through sales with recourse to third parties (bilateral contracts or securitization operations) are recognised at fair value through comprehensive income. This classification results from the existing history of sales to third parties and from the management's perspective regarding the existing assets. In regulated activities, the regulator establishes, through the tariff adjustment mechanism, the criteria to recognise gains or losses of one period in future periods. The tariff adjustments accounted for in the EDP Group financial statements represent the difference between the amounts invoiced by Portuguese regulated companies (based on the applicable tariffs published by ERSE in December of the previous year) and the regulated revenue calculated based on actual costs. The assets or liabilities resulting from the tariff adjustments are recovered or returned through the electricity and gas tariffs charged to customers in subsequent periods. Decree-Law 165/2008 of 21 August recognised the unconditional right of the regulated operators of the electric sector to recover the tariff adjustments under a regime identical to the one used for the tariff deficits. Consequently, EDP Group booked under the income statement caption Revenues from energy sales and services and other - Energy and access, the effects resulting from the recognition of tariff adjustments, against Debtors and other assets from commercial activities. According to the referred Decree-Law, the tariff adjustments determined annually, will be recovered by the regulated operators even in case of insolvency or cease of operations. ERSE is the entity responsible to establish the method to ensure that the entity entitled to these rights continues to recover the tariff adjustments until its complete payment. The Decree-Law also allows the transfer of the right to receive the tariff adjustment to third parties, in whole or in part, through future electricity tariffs. Decree-Law 87/2011 of 18 July establishes the unconditional right of regulated operators in the natural gas sector to recover tariff adjustments and related interest expenses, notwithstanding the form of the future payment or situations of insolvency and cessation of operations, and allows the transfer to third parties of the right to receive tariff adjustments. The EDP Group recorded in the income statement, under the caption Revenues from energy sales and services and other - Gas, the effects of the recognition of tariff adjustments of Natural Gas, against Debtors and other assets from commercial activities and Trade payables and other liabilities from commercial activities. x) CO2 Licenses and greenhouse gas emissions The Group holds CO2 Licenses in order to deal with gas emissions resulting from its operational activity and Licenses for trading. The CO2 and gas emissions Licenses held for its own use are booked as intangible assets at the acquisition cost. CO2 licenses consumption is recorded in accordance with the weighted average price of the CO2 and gas emissions Licenses held for consumption in that year. The Licenses held by the Group for trading purposes are booked under Inventories (see l)). y) Statement of Cash Flow The Statement of Cash Flow is presented under the indirect method, by which gross cash flows from operating, financing and investing activities are disclosed. The Group classifies cash flows related to interest and dividends paid as financing activities and interest and dividends received as investing activities. 

Integrated Annual Report 2022 Financial Statements and Notes 248 z) Group concession activities in the scope of IFRIC 12 EDP Group applies IFRIC 12 to the public-private concession contracts in which the public entity controls or regulates the services rendered through the utilisation of certain infrastructure as well as the price for such services and also controls any significant residual interest in the infrastructure. The infrastructures allocated to concessions are not recognised by the operator as property, plant and equipment or as financial leases, as the operator does not control the assets. These infrastructures are recognised according to one of the following accounting models, depending on the type of remuneration commitment of the operator assumed by the grantor within the terms of the contract: Financial Asset Model This model is applicable when the operator has an unconditional right to receive certain monetary amounts regardless of the level of use of the infrastructure within the concession and results in a financial asset recognition, booked at amortised cost. Intangible Asset Model This model is applicable when the operator, within the concession, is remunerated on the basis of the level of use of the infrastructure (demand risk) and results in an intangible asset recognition. Mixed Model This model is applicable when the concession includes simultaneously guaranteed remuneration and remuneration based on the level of use of the infrastructure within the concession. Intangible assets within concessions are amortised over their respective useful lives during the concession period. The Group carries out impairment tests to the intangible assets within concessions whenever events or circumstances may indicate that the book value of an asset exceeds its recoverable amount, being any impairment recognised in the income statement. Grants received from customers related to assets within concessions are delivered to the Group on a definitive basis, and, therefore, are not reimbursable. These grants are deducted from the value of the assets allocated to each concession. The concession contracts that currently exist in EDP Group are mainly based in the Intangible Asset Model, namely in the electricity special regime production concessions (PRE) in Portugal and in the Mixed Model, namely in the electricity distribution concessions in Portugal and in Brazil. aa) Institutional partnerships in North America The Group has entered in several partnerships with institutional investors in North America (EDPR NA), through operating agreements with limited liability companies that apportion the cash flows generated by the wind farms between the investors and the Company and allocates the tax benefits, which include Production Tax Credits (PTCs), Investment Tax Credits (ITC) and accelerated depreciation, largely to the investor. The institutional investors purchase their minority partnership interests for an upfront cash payment with an agreed targeted internal rate of return over the period that the tax credits are generated. This anticipated return is computed based on the total anticipated benefit that the institutional investors will receive and includes the value of PTC’s / ITC's, allocated taxable income or loss and cash distributions received. The control and management of these wind farms are a responsibility of EDP Group and they are fully consolidated in these financial statements. The financial instruments held by the institutional investors issued by the partnerships represent compound financial instruments as they contain characteristics of both financial liabilities and equity. The Group has determined that at the funding dates, the fair values of the original proceeds is equal to the fair values of the liabilities at that time and no value was assigned to the equity component. Subsequently, these liabilities are measured at amortized cost. This liability is reduced by the value of tax benefits provided and cash distributions made to the institutional investors during the contracted period. The value of the tax benefits delivered, primarily accelerated depreciation and ITC are recognised as Income from institutional partnerships on a pro-rata basis over the useful life of the underlying projects and, from 1 January 2021 onwards, over the 5-year recapture period, respectively (see note 8). The value of the PTC's delivered are recorded as generated. This liability is increased by an interest accrual that is based on the outstanding liability balance and the targeted internal rate of return agreed. 

Integrated Annual Report 2022 Financial Statements and Notes 249 After the flip date, the institutional investor retains a non-significant interest for the duration of the structure. This non-controlling interest is entitled to distributions ranging from 2.5% to 10% and taxable income allocations ranging from 5% to 10%. EDPR NA has an option to purchase the institutional investor’s residual interest at fair market value during a defined period following the flip date. Post flip non-controlling interests is the portion of equity that is ascribed to the institutional investor in the institutional equity partnership at flip date. This amount is reclassified from the total equity attributable to the Parent to non-controlling interests caption in the period in which the flip date takes place. ab) Disposal of assets under Asset Rotation strategy The Asset rotation strategy allows EDP Group to crystallize the value of a project by selling with loss of control, and reinvesting the proceeds in another projects, targeting greater growth. Typically, the developer retain the role of O&M supplier. The gains on disposals under this strategy are recognised in the caption Other income. 3\. Recent accounting standards and interpretations issued Standards, amendments and interpretations issued effective for the Group The amendments that have been issued and that are already effective and that the Group has applied on its financial statements, with no significant impacts, are the following: ● IFRS 3 (Amended) - Reference to the Conceptual Framework; ● IAS 16 (Amended) - Proceeds before Intended Use; ● IAS 37 (Amended) - Onerous Contracts – Cost of Fulfilling a Contract; and ● Annual Improvement Project (2018-2020). Standards, amendments and interpretations issued but not yet effective for the Group The standards, amendments and interpretations issued but not yet effective for the Group (whose effective application date has not yet occurred or, despite their effective dates of application, they have not yet been endorsed by the EU), which impact is being evaluated, are the following: ● IAS 12 (Amended) - Deferred tax related to assets and liabilities arising from a Single Transaction The IASB amended IAS 12 - Income taxes, to clarify the recognition of deferred tax on particular transactions that, on initial recognition, give rise to equal amounts of taxable and deductible temporary differences. The amendments target the recognition of deferred tax assets and liabilities in respect of: \- Right-of-use assets and Lease liabilities; and \- Provisions for dismantling and decommissioning and the corresponding amounts recognised as part of the cost of the related asset. Within the adoption of these amendments, effective on 1 January 2023, EDP Group has analysed the potential impacts. As of 31 December 2022, EDP Group has recognised in its Consolidated Statement of Financial Position the net deferred tax assets and liabilities regarding dismantling and lease liabilities for those jurisdictions where those amounts are not deductible until the payment date. Therefore, on 1 January 2023, EDP Group will breakdown these net deferred tax assets and liabilities regarding dismantling and lease liabilities, whenever applicable, being estimated an increase between 223 and 243 million Euros in the captions Deferred tax assets and Deferred tax liabilities. ● IFRS 17 - Insurance Contracts (and amendments related to initial application and comparative information) In preparation of the adoption of IFRS 17, effective as of 1 January 2023, the EDP Group carried out an analysis of the contracts of the subsidiary Energia RE - Sociedade Cativa de Resseguro. From the analysis performed, it was concluded that all contracts are eligible, and thus classified, within the Premium Allocation Approach (simplified model) measurement method provided for in IFRS 17. Thus, no material accounting impacts were determined for the EDP Group resulting from the adoption of IFRS 17, in replacement of IFRS 4. The standards, amendments and interpretations issued but not yet effective for the Group (whose effective application date has not yet occurred or, despite their effective dates of application, they have not yet been endorsed by the EU) for which no significant impact is expected, are the following: ● IAS 1 (Amended) - Classification of Liabilities as Current or Non-current; ● IAS 1 (Amended) - Disclosure of Accounting Policies; ● IAS 8 (Amended) - Definition of Accounting Estimates; and ● IFRS 16 (Amended) - Lease liability in a sale and leaseback. 

Integrated Annual Report 2022 Financial Statements and Notes 250 4\. Critical accounting estimates and judgements in preparing the financial statements IFRS requires the use of judgement and the making of estimates in the decision process regarding certain accounting treatments, with impact in total assets, liabilities, equity, costs and income. The actual effects may differ from these estimates and judgements, namely in relation to the effect of actual costs and income. The main accounting estimates and judgements used in applying the accounting policies are discussed in this note in order to improve the understanding of how its application affects the Group’s reported results and disclosures. A broader description of the accounting policies employed by the Group is disclosed in note 2 - Accounting policies. Considering that in many cases there are alternatives to the accounting treatment adopted by EDP Group, the reported results could differ if a different treatment was chosen. The Executive Board of Directors believes that the choices made are appropriate and that the financial statements present fairly the Group operations in all material respects. Financial asset related with infrastructure concession contracts in Portugal The caption “Amounts receivable from concessions - IFRIC 12”, refers to the financial assets receivable by EDP Group companies that operate infrastructures under concession contracts, and arises from the unconditional right to receive this amount regardless of the utilisation level of the infrastructures covered by the concession. In these companies is included E-Redes – Distribuição de Eletricidade, S.A. as the National Distribution Network (RND) concessionaire, which comprises the medium and high voltage network (MT and HT), and low voltage distribution networks (LT), being these concessions exercised exclusively through public service concession contracts. The RND’s operation, which is part of the HT and MT, is carried out through a public service concessions’ attribution, by the Portuguese State. On the other hand, the right to distribute low voltage electricity is attributed to the Portuguese mainland municipalities. The legislation that establishes the basis of each concession sets up that the ownership or possession of the goods assigned to these concessions revert to the concessionaires at the end of their respective concessions. They also establish that in return for the assets returned to grantors, whether State or municipalities, compensation corresponding to the assets’ book value assigned to the concession, net of amortisations, financial contributions and non-refundable subsidies will be paid. Therefore, the assets’ estimated residual value at the end of each concession constitutes a financial asset, and the remaining fair value component of the concession assets is an intangible asset to be amortised over its useful life. Hence, the end date of each concession is one of the main assumptions to determine the amount of the financial and intangible assets. In May 2017 Law 31/2017 was approved, which lays down the principles and general rules concerning the organisation of public tendering procedures for the awarding, by contract, of the municipal LT concessions’ operation in the Portuguese mainland. This Law foresee the simultaneous launch, in 2019, of public tender procedures for all municipalities that do not opt for direct management of the electricity distribution activity. However, the new Decree-Law 15/22, of January 2022, determined the automatic extension, without the need for further terms, of the current concession contracts for electricity distribution networks in BT, including those that had already reached their term, until the effective entry into operation of a new contractor, following the tenders for the attribution of BT concessions that will be held in the future. On the other hand, there is currently no set date in the legislation for the holding of future tenders for the attribution of BT concessions. In this context, at this date it is not yet possible to predict the end date of the low voltage concession contracts currently in force, so an annual extension of contracts that have already reached the originally planned end date is assumed. Thus, with reference to 31 December 2022, the financial asset and the intangible asset related to the concessions whose contracts have not yet ended were determined based on the respective expiry dates and, for the remaining concessions, the financial asset and the intangible asset are determined assuming the validity of the contracts until 31 December of the year following the year in question. Measurement criteria of the concession financial receivables under IFRIC 12 in Brazil In 2012, the Provisional Measure 579/12 was published in Brazil, meanwhile converted into Law 12.783/13, which determines that the amount of the indemnisation payable to the distribution companies regarding the assets not amortised or depreciated at the end of each concession, should be determined based in the methodology of the Value of Replacement as New (VNR). The indemnisation amount variation is booked against Revenues from energy sales and services and other. This amount corresponds to the difference between the residual value determined based on the value of replacement as new and the residual value determined based on the historical cost. 

Integrated Annual Report 2022 Financial Statements and Notes 251 ANEEL reviews the VNR, through the valuation report of the Regulatory Remuneration Base, every three years for EDP Espírito Santo and every four years for EDP São Paulo, as established in the concession contracts. Within these periods the distribution companies use their best estimate for the VNR. The use of different assumptions could result in different values of financial assets, with the consequent impact in the Statement of Financial Position (see note 26). Impairment of long term assets and Goodwill Impairment tests are performed whenever there is a trigger that the recoverable amount of property, plant and equipment and intangible assets is less than the corresponding net book value of the assets. On an annual basis, the Group reviews the assumptions used to assess the existence of impairment in goodwill resulting from acquisitions of shares in subsidiaries. The assumptions used are sensitive to changes in macroeconomic indicators and business assumptions used by management. The investments in subsidiaries, on a company basis, and in associates are reviewed when circumstances indicate the existence of impairment. Considering the uncertainties regarding the recoverable amount of property, plant and equipment, intangible assets and goodwill as they are based on the best information available, changes in the assumptions could result in changes on the determination of the amount of impairment and, consequently, in results (see notes 12 and 19). Measurement of the fair value of financial instruments Fair values are based on listed market prices, if available. Otherwise, fair value is determined either by the price of similar recent transactions under market conditions, or determined by external entities, or based on valuation methodologies, supported by discounting future cash flows techniques, considering market conditions, time value, yield curves and volatility factors. These methodologies may require the use of assumptions or judgements in determining fair values. Consequently, the use of different methodologies and different assumptions or judgements in applying a particular model, could generate different financial results from those reported. Classification of financial instruments Financial instruments’ classification as debt or equity requires judgement in the interpretation of contractual clauses and in the evaluation of the existence of a contractual obligation to deliver cash or other financial assets. Review of the useful life of the assets The Group reviews annually the reasonableness of the assets' useful lives that are used to determine the depreciation rates of assets assigned to the activity. When applicable, the Group changes the depreciation charge of the year, prospectively, based on such review. Useful lives of generation assets - Hydro independent generator in Brazil The hydro generation assets in Brazil for independent generators are amortised during their estimated useful lives, considering the existing facts and circumstances at the date of preparation of the financial statements. This includes, among other issues, EDP's best expectations of the useful lives of such assets, which are consistent with the useful lives defined by ANEEL, the respective contractual residual indemnification values at the end of each concession period, as well as related technical and legal opinions. The remaining period of amortisation and the indemnification values at the end of the concessions may be influenced by changes in the regulatory legal framework in Brazil (see note 16). Lease Liabilities The Group recognises right-of-use assets and lease liabilities, if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset, the Group assesses whether: i) the contract involves the use of an identified asset; ii) it has the right to obtain substantially all of the economic benefits from the use of the asset throughout the period of use; and iii) it has the right to direct the use of the asset. EDP Group uses judgement on its assessment, namely concerning the termination and extension contract options and the determination of the incremental borrowing rate to be applied for each portfolio of leases identified (see notes 17 and 39). 

Integrated Annual Report 2022 Financial Statements and Notes 252 Tariff adjustments Portugal Tariff adjustments in Portugal represent the difference between costs and income of the National Electricity, estimated at the beginning of each period for purposes of calculating the tariff, and the actual costs and income of the System established at the end of each period. The tariff adjustments assets or liabilities are recovered or returned through electricity and gas tariffs to customers in subsequent periods. Decree-Law 237-B/2006 of 19 December, and Decree-Law 165/2008 of 21 August, recognised an unconditional right of the operators of the electricity sector to recover the tariff adjustments and related interest expenses, notwithstanding the form of the future payment or situations of insolvency and cessation of operations. Additionally, the legislation allows the transfer to third parties of the right to receive tariff adjustments. Therefore, under this legislation, regulated companies may provide to third parties, in whole or in part, the right to receive the tariff adjustments through the electricity tariffs. In accordance with the accounting policy in force, the EDP Group books under the caption Revenues from energy sales and services and other - Electricity and network access, the effects of the recognition of tariff adjustments in the electricity sector, against Debtors and other assets from commercial activities and Trade payables and other liabilities from commercial activities. Brazil On 25 November 2014, ANEEL made addendums to the concession contracts with brazilian electric distribution companies to reduce significant uncertainties regarding to the recognition and realization of regulatory assets/liabilities that existed since 2010, when the IFRS were adopted in Brazil. As a consequence, the CPC ("Comitê de Pronunciamentos Contábeis") issued on 28 November 2014, the OCPC 08 (Recognition of Certain Assets and Liabilities in Accounting and Financial Reports of Electric Distribution) which determines how to treat these regulatory assets/liabilities in the financial statements. Therefore, on 10 December 2014, EDP Brasil signed the Fourth and Fifth Addendum to the Concession Agreement, where it was established that, in the case of concession termination, the outstanding balances of any failure of payment or reimbursement by the tariff (assets and liabilities), will be considered on the indemnity calculation, based on the regulator pre-established regulations. EDP Group considers, based on the issued legislation (Portugal and Brazil), that the requirements for the recognition of tariff deficits as receivables and payables against the income statement of the period have been satisfied (see notes 7, 26 and 38). Revenue recognition Energy sales revenue is recognised when the monthly energy invoices are issued, based on actual meter readings or estimated consumption based on the historical data of each consumer. Revenue relating to energy to be invoiced, regarding consumption up to the balance sheet date but not measured, is booked based on estimates that take into consideration factors such as consumption in prior periods and analysis relating to the energy balance of the operations. The use of different estimates and assumptions could affect the Group’s revenue and, consequently, its reported results (see note 7). Income taxes The Group is subject to income taxes in several jurisdictions. Certain interpretations and assumptions are required in determining the global amount of income tax. There are several transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business. It is the Group's understanding that, in general, the tax treatment follows the accounting treatment, and therefore, no significant tax adjustments have been made to the accounting records arising from the implementation of the new standards. Different interpretations and assumptions could result in a different level of income taxes, current and deferred, recognised in the period (see note 14). Pensions and other employee benefits Determining pension and other employee benefits liabilities requires the use of assumptions, including actuarial projections, estimated rates of return on investments, discount rates and pension and salary growth and other factors that can impact the cost and liability of pension plans, medical plans and other benefits. Changes in the assumptions could materially affect the amounts determined (see note 35). 

Integrated Annual Report 2022 Financial Statements and Notes 253 Provisions for dismantling and decommissioning of power generation units EDP considers to exist legal, contractual or constructive obligations to dismantle and decommission property, plant and equipment assets allocated to electricity generation operations. The Group records provisions in accordance with existing obligations to cover the present value of the estimated cost to restore the locations and land where the electricity generation units are located. EDP Group provisions include the calculation of the present value of the expected future liabilities. The use of different assumptions and judgement from those referred could lead to different financial results than those considered (see note 36). Entities included in the consolidation perimeter In order to determine which entities must be included in the consolidation perimeter, EDP Group evaluates whether it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee ("de facto" control). This evaluation requires the use of judgement and assumptions in order to conclude whether the Group is in fact exposed to the variability of returns and has the ability to affect those returns through its control over the investee. Other assumptions and judgements could lead to a different consolidation perimeter of the Group, with direct impact on the consolidated financial statements (see note 6). Business combination Under IFRS 3 (Business Combination) in a business combination, the acquirer shall recognise and measure in the consolidated financial statements the assets acquired and liabilities assumed at fair value at the acquisition date. The difference between the purchase price and the fair value of the assets and liabilities acquired leads to the recognition of goodwill or a gain from a purchase at a low price (bargain purchase). The fair value determination of the assets acquired and liabilities assumed is carried out internally or by independent external evaluators, using the discounted cash flows method, using the replacement cost or other fair value determination techniques, which rely on the use of assumptions including macroeconomic indicators such as inflation rates, interest rates, exchange rates, discount rates, sale and purchase prices of energy, cost of raw materials, production estimates and business projections. Consequently, the determination of the fair value and goodwill or gain from a purchase at a low price is subject to numerous assumptions and judgments and therefore changes could result in different impacts on results (see note 49). Fair value measurement of contingent consideration Contingent consideration from a business combination or a sale of a financial investment is measured at fair value at the acquisition date as part of the business combination or at the date of the sale in the event of a sale of a financial investment. This contingent consideration is subsequently remeasured at fair value at each report date. Fair value is based on discounted cash flows. The main assumptions consider the probability of achieving each objective and the discount factor, corresponding to the best estimates of management at each report date. Changes in assumptions could have significant impact on the values of contingent assets and liabilities recognised in the financial statements (see notes 27 and 39). Acquisition of assets out of the scope of IFRS 3 In order to assess whether an acquisition of an asset or a group of assets is a business, the Group identifies the elements in the acquired entity (inputs, processes and outputs), assesses the capability to create outputs (it should have at a minimum, an input and a substantive process to be assessed as a business) and, finally, assesses the capability of market participants to continuing to create outputs (conducting the activities as a business). In the case of an integrated set of activities that is in an early-stage of development and has not started to generate outputs, the Group considers other factors to determine whether it constitutes a business, such as if: (i) planned principal activities have begun; (ii) employees, intellectual property, and other inputs and processes are present; (iii) a plan to produce outputs is being pursued; and/or (iv) access to customers who will purchase the outputs can be obtained. Generally, an early-stage entity that has employees capable of developing an output will be considered a business. Therefore, in application of the above, the Group concludes that IFRS 3 is not applicable when there are no outputs at the acquisition date due to an early-stage of development, and the acquired process(es) cannot be considered substantive. Thus, the acquisition of an asset or a group of assets that does not fulfill the conditions to be considered a business is classified as an acquisition of a company out of scope of IFRS 3. 

Integrated Annual Report 2022 Financial Statements and Notes 254 Contractual stability compensation - CMEC The approval in 2004 of the Decree-Law 240/2004, of 27 December, determined the early Power Purchase Agreements (PPA) extinction, and the adoption of a contractual stability compensation (CMEC), which EDP Produção entered into after signing the Contractual stability on 27 January 2005, approved by the competent Government member (Order 4672/2005, of 4 March). This mechanism includes three types of compensation: initial compensation, annual adjustment (or revisibility) and final adjustment. The last two types of compensation are relevant for this purpose. i) Contractual stability compensation – Annual revisibility mechanism During period I (2007/2017) of the contractual stability compensation mechanism, there was a correction on an annual basis, resulting from positive or negative deviations between the estimates made for the initial stability compensation calculation and actual amounts arising from an efficient performance, using the "Valorágua" model, as established in the Decree-Law 240/2004. Later, Order 4694/2014 was published to define the guidelines of the annual revisibility calculation with respect to the revenues from the ancillary services market, regarding power plants under CMEC. Revisibility amounts for the years 2007 to 2014 were determined and approved by the Member of the Government responsible for the energy sector, and were contested by EDP Produção: a) As regards the approval of the 2011 and 2012 revisibilities, the fact that it did not consider the costs incurred with the social tariff in the calculation of the revisibilities; and b) As regards the approval of the 2014 revisibility, the fact that it did not take into account in the calculation of the revisibility the costs incurred with the social tariff and CESE. Regarding the revisibility to the year 2012, the Administrative Court dismissed the special administrative action brought by EDP Produção, not recognizing the costs with the financing of the Social Tariff for the determination of the amount of the annual adjustment of the CMEC relating to 2012\. EDP Produção, not agreeing with the decision, filed, on 9 January 2023, an Appeal, with suspensive effect, to the Southern Central Administrative Court. The annual revisibility of 2015 was approved by the Government member responsible for the energy sector in 20 October 2020 in the amount of 62.7 million Euros, after deducting an amount of 72.9 million Euros related to the alleged overcompensation of CMEC, due to their participation in the ancillary services market, in the period between 2009 and the first quarter of 2014 (see section Ancillary Services). EDP Produção challenged the order for ratifying the annual revisibility for the year 2015 on 19 January 2021, as it did not agree with the assumption of overcompensation within the scope of its performance in the system services market, between 2009 and 2014 and, consequently, do not agree with the deduction of the underlying value (72.9 million Euros) in that revisibility. It should also be noted that EDP Produção has already contested the imposition of a fine by the Competition Authority on matters of the same scope. The challenge also covered the non- consideration of the Social Tariff and CESE amounts paid by the centrals operating under the CMEC regime and also the non-approval of the annual revisibilities from 2016 to 2017, which still await the respective approval by the Government member responsible for the area of energy. ii) Contractual stability compensation – Final Adjustment The CMEC’s Final Adjustment is calculated in accordance with number 7 of article 3rd and Annex IV of Decree-Law 240/2004, of 27 December. The State budget for 2017 (Law 42/2016 of 28 December) determined, in its article 170, that the final adjustment amount is determined and based on a study prepared and presented by ERSE. This entity had the technical support of EDP Produção and REN (Work Team), legally enforced. Accordingly, the technical group EDP/REN has presented to ERSE its report on the CMEC final adjustment calculation, which was achieved by strictly following the calculation methodology described in Decree-Law 240/2004, of 27 December. This calculation, performed by the technical group EDP/REN was presented to ERSE and comes to a range of amounts between 256.5 and 271 million Euros. At the end of September 2017, ERSE has also presented to the Government its report on the calculation of the CMEC final adjustment, reaching an amount of 154 million Euros, which was provisionally considered in the document of Tariffs and Prices for 2018. In the Financial statements as at 31 December 2017, EDP Group has included its best estimate of the CMEC final adjustment, by recognising an asset in the amount of 256.5 million Euros against deferred income, based on the methodology established for this purpose in Decrew-Law 240/2004, of 27 December, and in the legal opinions obtained in the meantime on this understanding. 

Integrated Annual Report 2022 Financial Statements and Notes 255 On 3 May 2018, EDP was notified (through a DGEG’s letter from 25 April 2018) that the CMEC final adjustment had been officially approved, according to ERSE’s proposal, in the amount of 154 million Euros. EDP reflected this reality in its financial statements as of 31 December 2018, recognising a provision by the difference in the final adjustment amounts already recognised in the Group's revenues. On 31 December 2021 EDP maintains the provision in its accounts (see note 36). Considering that the administrative act contained in the Dispatch of approval of the SSE of 25 April 2018 lacks technical, economic and legal basis, and that, in particular, it does not apply the calculation methodology contained in Decree-Law 240/2004, of 27 December, and which would lead to the determination of an amount close to the one determined by the technical group, on 3 September 2018, EDP Produção has legally contested it. "Clawback" - Portuguese regulatory mechanism to ensure the competitive balance in the wholesale electricity market, in particular Iberian Following some tax changes occurred in Spain, which affected electricity generators operating in this country, Decree-Law 74/2013, of 4 June, was approved in Portugal, which aimed to rebalance the competition between electricity generators operating in Portugal and other players operating in Europe. Pursuant to relate diploma and its regulations, in order to restore such balance, the power plants operating on a market regime situated in Portugal, which were not covered by the PPA or CMEC regime, should pay to the System an amount per MWh produced. The amount payable should consider, on one hand, an estimate of the impact that the off-market events in the European Union (such as the above-mentioned tax changes in Spain) would have in pool prices, and on the other hand, the existence of national extra-market events that affect the competitiveness of electricity generators operating in Portuguese territory. Consequently, a net competition advantage would allegedly arise to generators operating in Portugal. Under this mechanism regulation – commonly known as clawback – Social tariff and CESE were determined by Dispatch 11566-A/2015, of 3 October, as off-market events that should be considered as competitive disadvantages of generators operating in Portugal. Dispatch 7557-A/2017, of 25 August, superseded Dispatch 11566-A/2015 (which defined the variables for the computation formula of the amount to be paid by each of the power-generating plants under Decree-Law 74/2013, of 4 June, for each injected MWh) in its entirety. It states that ERSE, after consulting DGEG, should present proposals for a new definition of the variables, as well as reference terms for the new study. Subsequently, the Dispatch 9371/2017, of 24 October, partially nulled the Dispatch 11566-A/2015, in relation to the decisions presented under its numbers 11 and 12 (the deduction of social tariff and CESE costs in the unit price). ERSE was asked to consider in 2018 UGS tariff, the recovery, in benefit of the consumers, of the amounts allegedly unproperly included in previous years’ tariffs (2016 and 2017). Dispatch 9955/2017, of 17 November, defines a new amount for the estimate of the off-market events’ impact in EU, which is -4.75 €/MWh, with retroactive effects as at August 24. Following these Dispatches, the document of prices and tariffs for 2018 has included a clawback amount of around 90 million Euros to be returned to tariffs, which includes power plants operating under CMEC and estimated generation. Based on its interpretation of the Law, as well as on legal opinions obtained, EDP Produção considers that the Decree-Law 74/2013, of 4 of June, aims to re-establish a situation of competition balance between generators operating in Portugal and their peers operating in other European countries, which means to consider as off-market events all the taxes and contributions that fall only over generators located outside of Portugal (particularly in Spain), as well as all the taxes and contributions that fall only over generators located in Portugal. Consequently, in the EDP Produção’s understanding, supported by legal opinions, Dispatch 9371/2017 and 9955/2017 have completely distorted the clawback mechanism, having filed its legal action in January 2018. In the Financial statements as at 31 December 2018, EDP Group has included the clawback amount as calculated by EDP Produção, regarding the legislation in place in each period, namely Decree-Law 74/2013, of 4 of June, Order 225/2015, Ordinance 9371/2017 and Dispatch 9955/2017. It is important to notice that this mechanism is not applicable to power plants in 2018 still operating under CMEC regime. However, this situation was subsequently changed and disputed by EDP Produção, as mentioned below. On 5 October 2018, the Spanish legislature, by the sixth and seventh additional lines on Article 21 of Royal Decree-Law 15/2018, suspended the 7% tax on electricity generation approved in 2012 for a period of six months, from the beginning of October 2018 to the end of March 2019. This tax suspension corresponds to the suspension of the off-market event verified within the European Union, which is considered in the clawback calculation. 

Integrated Annual Report 2022 Financial Statements and Notes 256 Following the temporary suspension of the tax on electricity production in Spain: \- Order 895/2019 of 23 January, establishing the suspension of the "Clawback" was approved for a period of 6 months as from 1 October 2018; \- The Tariff and Price Document for 2019, published on 17 December 2018, estimates a Clawback value of € 4.18/MWh, to be applied after the end of the suspension period (more specifically from 6 April 2019); \- ERSE informed EDP Produção that any clawback invoicing relating to the referred suspension period should be deleted or cancelled; \- The State Budget Law for 2019 provided that "the Government shall, until the end of the first quarter of 2019, review the regulatory mechanism designed to ensure the balance of competition in the wholesale electricity market in Portugal, provided for under DL 74/2013, of 4 June, adapting it to the new rules of the Iberian Electricity Market, with the aim of creating harmonized regulatory mechanisms that reinforce competition and protect consumers". On 1 April 2019, the suspension of the tax on the production of electric energy in Spain was terminated, and it became effective again. From that moment, the "clawback" invoiced to EDP Produção was resumed, based on a value of 4.75€/MWh. On 9 August 2019, Decree-Law 104/2019 was published, which makes the first amendment to Decree-Law 74/2013, of 4 June, by changing the scope of the clawback mechanism. Previously, “electricity producers under the ordinary regime and other producers not covered by the guaranteed remuneration regime" were subject to clawback. With the publication of this diploma, the CMEC centrals are now included in the scope of the clawback. Considering that this scope contradicts the Decree Law 240/2004, of 27 of December, EDP Produção proceeded to its challenge. The same Decree-Law introduced the possibility to define CIT (corporate income tax) – advanced payment, and on 26 September 2019 was published the Order 8521/2019, which set the amounts of advanced payment related to the clawback mechanism at 2.71€/MWh for coal-fired power plants and 4.18€/MWh for other power plants. In the Tariff and Price Document for 2020, published on 16 December 2019, ERSE considered the unit values defined in Dispatch 8521/2019, correcting only the value applicable to coal to 1.23 € / MWh, due to the increase in the ISP tax percentage and CO2 addition planned for 2020. EDP Produção presented on 10 March of 2020 an action seeking a declaration of nullity or annulment of that administrative act by ERSE. On 27 December 2019, Dispatch 12424-A / 2019 was published, which identifies as national extra-market events to be considered in the Study to be prepared by ERSE until April 2020 (with reference to 2019) under the Clawback mechanism, the taxation of petroleum and energy products used in the production of electricity (ISP), CESE and the Social Electricity Tariff. On 30 June 2020, Dispatch 6740/2020 was published by the Secretary State of Energy (SEAE) which establishes the CIT (corporate income tax) – advanced payment to be applied in 2020 to electric power producers covered by the "Clawback" mechanism. The value of CIT (corporate income tax) – advanced payment for the year 2020 is set at € 2.24/MWh for plants that are not subject to extra market internal events, that is, only to some renewable energy producers in the market with the exception of the power generation centers included in the scope of internal extra-market events identified. On 22 October 2020, Dispatch 10177/2020, issued by the SEAE Office, was published, which determines the final compensation of the “Clawback” for the year 2019, considering the ISP regime as the only internal off-market event within the National Electrical System (SEN), thus determining a value of € 2.24 / MWh for hydro, gas and PRE on the market and 0.68€/MWh for coal power plants. This determination is not consistent with that contained in Dispatch 12424-A/2019, of 27 December, which identifies ISP, CESE and Social Tariff as internal off-market events for 2019. EDP Produção challenged Order 10177/2020 on 22 January 2021. On 25 June 2021, the Spanish legislator, within the scope for the adoption of urgent measures regarding energy taxation due to the high prices verified in the MIBEL, published the Royal Decree-Law 12/2021, which, among others, proceeds the suspension of the 7% tax on the production of electricity, approved in 2012, for a period between 1 July and 30 September 2021 (3 months), and with effects on the determination of the “Clawback”. Following Royal Decree-Law 17/2021, the Spanish legislator has once again suspended the 7% tax on electricity production for another 3 months, between 1 October and 31 December of 2021. Following the temporary suspension of the tax on the production of electricity in Spain, Dispatch 6398-A/2021, of 29 June, was published, which established the suspension of the “Clawback” in the period between 1 July 2021 and 30 September 2021, and Order 9975/2021, of 14 October, which determines the suspension of this mechanism between 1 October and 31 December 2021. 

Integrated Annual Report 2022 Financial Statements and Notes 257 On 14 October 2021, Order 9974/2021, of the SEAE Office, was published, which determines the final compensation of the "Clawback" for the year 2020, considering as the only extra-market event within the National Electric System the regime of ISP (noting that it is consistent with the Dispatch that approved the final value for the year 2019), resulting in the following “Clawback” values: 3.64€/MWh for hydro plants and Special Regime Production (PRE) in the market; 3.42€/MWh for CCGTs; and 2.16€/MWh for coal plants. This determination is not coherent with the goals and rationale underlying the “Clawback” mechanism, as it does not admit the Social Tariff and CESE as internal extramarket events. EDP Produção challenged Order 9974/2021 on 14 January 2022. The Spanish legislator suspended again the 7% tax on electricity production for another 6 months, through Royal Decree-Ley 29/2021, of 21 December (for the period between 1 January and 31 March 2022) and Royal Decree-Ley 6/2022, of 29 March (for the period between 1 April and 30 June 2022). Following this temporary suspension of the tax on electricity production in Spain, Order 1322/2022 of 1 February was published, which established the suspension of the “Clawback” between 1 January and 31 March 2022, and Order 6287/2022, of 19 May, which extended this suspension until 30 June 2022. More recently, the Spanish legislator, due to the maintenance of high prices in the MIBEL resulting, above all, from the Russia-Ukraine conflict, resumed the suspension of the 7% tax on electricity production until the end of 2022, through the Royal Decree-Ley 11/2022, of 25 June, and Order 9838/2022, of 9 August, determined the suspension of the “Clawback” for the period between 1 July and 31 December 2022 in Portugal. In the year 2023 the tax on generation in Spain is suspended, in accordance with Royal Decree-Ley 20/2022 of 27 December, so the suspension of the "Clawback” in Portugal is also expected in the same period. Social Tariff Scheme EDP Group filed a request to the European Commission to assess the compliance of the Social Tariff funding mechanism, fully supported by ordinary regime generators, with the rules and principles of European Union law. On this, since 2011, EDP has already been charged more than 530 million Euros. EDP does not question the existence of the Social Tariff, and agrees with its purpose, but cannot, in light of the current regime, conform with the terms in which the legislator enshrined its method of financing. In fact, in Spain, similar mechanisms for financing the price of electricity were considered not to comply with the legal framework and were therefore subject to modification. The verification request aimed to obtain confirmation on the inadequacy of the current national social tariff financing mechanism and to prompt the review of national legislation on this financing mechanism. The European Commission recognised the discriminatory nature of the financing mechanism for the social tariff in Portugal and informed that it would keep monitoring the evolution of the social tariff in Portugal, particularly in the context of the revision of tariffs for 2023. In the 2023 tariffs, the social tariff discount continues to be attributed to eligible customers and the respective cost is being temporarily borne by the network operators, pending definition of the financing model for this cost. Ancillary Services i) Secondary regulation band service On 3 September 2018 the Autoridade da Concorrência (AdC) adopted a Note of Illegality, under which it intended to attribute to EDP Produção a behaviour of abuse of a dominant position in the secondary regulation band service. AdC claimed that EDP Produção restricted the offer of a segment of the Electricity System (the secondary regulation band or teleregulation service) between January 2009 and December 2013, limiting the capacity offer of its plants under CMEC regime to benefit market power plants, in order to benefit twice, to the detriment of consumers. On 28 November 2018, EDP Produção exercised its right to be heard and to defend itself in relation to the wrongful act was imputed and the sanctions it could incur, that is, it responded to the Note of Illegality. On 18 September 2019, AdC informed EDP Produção of its decision to condemn, imposing a fine of 48 million Euros, for alleged abuse of dominant position in the secondary regulation band market in mainland Portugal between January 2009 and December 2013. According to AdC, EDP Produção would have manipulated its offer of tele-regulation service or secondary regulation band, limiting the capacity offer of its CMEC power plants to offer it through its market power plants, benefiting in two ways: \- Highest compensation paid to CMEC plants (annual revisability), as their lower participation in the provision of secondary regulation band service would be below what would be expected (according to competitive market criteria); and \- The increase of the market price of the secondary bandwidth service, as a result of the limited supply by CMEC plants, favouring market- based power plants. 

Integrated Annual Report 2022 Financial Statements and Notes 258 On 30 October 2019, EDP Produção filed an appeal against this decision before the Competition, Regulation and Supervision Court (TCRS), awaiting the AdC's counter-allegations. On 20 May 2020, EDP Produção was notified of an order from TCRS, which, among other things, admitted its Appeal of Judicial Contestation, establishing a purely return effect and determining the payment of the fine imposed within 20 days. In this context, EDP Produção submitted requests, invoking supervening facts to demonstrate the considerable damage associated with a putative payment of the fine, and arguing defects in the decision that determined the attribution of a merely devolutive effect to the Judicial Challenge Appeal. However, despite EDP Produção's well-founded convictions about the possibility of providing a bank guarantee or bond, instead of paying the fine, the TCRS ended up determining the payment of the fine, which occurred on 20 October 2021. The trial started in September 2021 and on 10 August 2022, the TCRS confirmed the AdC's decision, maintaining the fine of 48 million Euros to EDP Produção for alleged abuse of dominant position. EDP Produção filed an appeal against the aforementioned decision to the Lisbon Court of Appeal on 30 September 2022. The EDP Group considers that EDP Produção did not abuse any dominant position, having acted strictly in accordance with the legal framework in force. On 29 September 2021, EDP Produção was cited in a class action filed by Associação IUS Omnibus based on the alleged abuse of dominant position in the secondary regulation band market between the beginning of 2009 and the end of 2013, requesting, in representation of consumers, a compensation in the amount of 94.8 million euros, as estimated by AdC in the scope of process PRC/2016/05. EDP Produção has already presented its defense within the legal deadline established for that purpose. A Order was issued, in which the court decided, among other things, to suspend the proceedings until a final decision is rendered in administrative offense case 309/19.0YUSTR. The appeal filed by EDP Produção with the Lisbon Court of Appeal regarding this decision to suspend the proceedings is pending. ii) CMEC's revisibility overcompensation On 20 October 2020, EDP Produção became aware, by letter sent by DGEG, of the dispatch of the SEAE regarding the approval of the revisibility for the year 2015, which is deducted in the amount of 72.9 million Euros, relating to the alleged overcompensation. In this respect, the EDP Group has registered a provision in the amount of 72.9 million Euros, and carried out a judicial appeal against the order of SEAE at the Administrative Court of the Lisbon Circle at 19 January 2021. Innovative Features On 9 July 2018, EDP has been notified, within the scope of a stakeholder hearing promoted by the DGEG, to present its opinion on the possibility of DGEG proposing to the Secretary of State for Energy an amount associated with the alleged "innovative features" introduced in CMEC regime regarding PPA, to a maximum amount of 357.9 million Euros. According to DGEG, this amount shall be associated with the lack of legal scope for tests on the availability of the CMEC plants (285 million Euros) and the ancillary services, mentioned above (72.9 million Euros). On 26 September 2018, EDP Produção was notified of the Order of the SEE of 29 August, which considers as an "innovative features" the topic "procedures for calculating the verified availability coefficient", quantified at 285 million Euros. This Order refers to the alleged lack of legal forecast of availability tests of CMEC plants. Considering that the Order in question lacks technical, economic and legal basis, on 8 October 2018 EDP Produção has submitted an administrative appeal. Subsequently, EDP Produção received a letter from ERSE dated 12 November 2018 and became aware of the Order of the SEE of 4 October, which, following the Order of 29 August, declared the annulment of the annual adjustments in the part in which they considered the alleged "innovative features" concerning the procedures for calculating the coefficient of availability. In the Tariff and Price Document for 2019, ERSE considered the refund of an amount of 90 million Euros for a portion of the 285 million Euros referred to, expecting that the remaining portion will be paid for a number of years that allow the CMEC to have zero tariff impact by including the 86.5 million Euros in the tariffs of 2020, 86.5 million Euros in tariffs of 2021 and 21.9 million Euros in 2022. Without having received any response to the gracious complaint filed on 1 February 2019, EDP Produção challenged in court the Orders of 29 August and 4 October and the Tariff and Price Document for 2019. In the Electricity Tariffs and Prices Document for 2020, approved by ERSE on 16 December 2019, that entity charged again 86.5 million Euros, as it had foreseen the previous year. Although the EDP Group considers that there were no innovative features weighted in CMEC adjustments, this aspect was reflected in these financial statements as of 31 December 2018, by recognising a provision of 285 million Euros. In 2019 EDP made the payment of 92,458 thousand Euros, during 2020 made the payment of 110,963 thousand Euros, during 2021 made the payment of 69,374 thousand Euros and during 2022 made the payment of 12,105 thousand Euros (see note 36) thus using the entirety of this provision on 31 December 2022. 

Integrated Annual Report 2022 Financial Statements and Notes 259 Hydro power plants of Fridão and Alvito On 17 December 2008, EDP Produção and the Portuguese State signed the Contract for the Implementation of the National Program for High Hydroelectric Potential Power Plants (PNBEPH) regarding the Hydro Power Plants of Fridão (AHF) and Alvito (AHA), with the payment, by EDP Produção of 231,700 thousand Euros. Of this amount, 217,798 thousand Euros relates to the exclusive right to explore the AHF during the concession period. EDP Produção followed up on the procedures for the implementation of these projects, having, in the case of the AHF, obtained a Favourable Environmental Impact Declaration and an Environmental Compliance Report of the Execution Project (RECAPE). On 22 October 2013, EDP Produção requested to the Minister of the Environment, Land Management and Energy, based on a change of circumstances, to postpone the signing of the concession contract for the AHF. This request was formally rejected on 2 May 2014, and the terms of the concession contract, were subsequently negotiated between EDP Produção and the Portuguese Environmental Agency (APA) and a specific date for the respective signature for 30 September 2015, which was revoked by the Government without rescheduling a new date. In 2016, following the beginning of the XXI Constitutional Government, the Government Program provided the reassessment of the PNBEPH. In this context, it was suspended, for three years, the execution of the Contract for the implementation of the AHF, as well as was agreed the annulment of the implementation Contract regarding AHA, through a Memorandum of Understanding signed on 5 December 2016, concluded by an agreement between the Portuguese State and EDP Produção on 11 April 2017. On 16 April 2019 EDP Produção received, by email, an official letter from the Ministry of the Environment and Energy Transition, dated 11 April 2019, informing the State's conclusion that there is no need for implementation of AHF to meet national targets for energy production from renewable sources and for reducing the emission of Greenhouse Gases, as well as "that the State does not find any reason to inhibit the construction of the Fridão Hydro Power Plant". Simultaneously, the Minister of the Environment and Energy Transition (MATE) announced at the National Assembly, in a hearing at the Environment, Land-use Planning, Decentralization, Local Power and Housing Committee, that the State's decision was not to build the AHF and that "the State will always comply with the contract but believes there are no reasons for any repayment of the amount that was given to the State ten years ago". It acknowledged, however, that there was no agreement with EDP on this matter. EDP Produção notified the Portuguese State to clarify that at no time did EDP express its intention to not proceed with the construction of power plants and to return all the investment already made, including the consideration paid on the provisional award, and, as well, to compensate it for other losses and damages resulting from the non-compliance, to be settled in a timely manner. The Group reclassified these Assets under construction to Other debtors and other assets and valued them in accordance with the principles defined in IFRS 9 (see note 27). On 24 January 2020, EDP Produção initiated an arbitration process against the State in which it claimed its rights. The arbitration hearing sessions took place during the month of April 2021 and in July 2021 the closing arguments were presented. In July 2022, the competent Arbitration Decision was handed down, obliging the State to refund to EDP Produção the aforementioned amount of 217,798 thousand Euros, which concerns the exclusive right to explore the AHF during the concession period. The other requests by EDP Produção and the State were dismissed. On 7 October 2022, the Portuguese State filed an appeal against the aforementioned Arbitration decision and EDP Produção presented its counter-claims on the 11 November 2022. On the 15 December 2022, the Supreme Administrative Court delivered the Judgment admitting the review appeal filed by the Portuguese State. In view of this decision, EDP filed an appeal with the Constitutional Court. EDP Produção submitted, on 13 December 2022, an appeal for the execution of the Arbitration Decision, demanding the payment of the amount in which the Portuguese State was sentenced, in the amount of 217,798 thousand Euros. The appeal was admitted. Sale of real estate by E-Redes – Distribuição de Eletricidade, S.A. In the 2009-2018 period, E-Redes – Distribuição de Eletricidade, S.A. (E-REDES) disposed a set of real estate that were unused for the activities of the various electricity distribution concessions, in the amount of approximately 52 million Euros, obtaining a total net value of gains of 33.9 million Euros (35.7 million Euros of gains and 1.7 million Euros of losses). In the regulated accounts sent to ERSE in April 2018, E-REDES identified the amount to be returned into tariffs related to the depreciation of the properties that were sold in the period 2012-2017. ERSE did not consider this amount in the 2019 rates and submitted the topic for further analysis. 

Integrated Annual Report 2022 Financial Statements and Notes 260 In the Tariffs for 2020, ERSE recognized the principle of profit sharing with the system and assumed the return into the tariffs of approximately 16.6 million Euros referring to half of the net gains obtained from the sale of real estate by E-Redes – Distribuição de Eletricidade, S.A. between 2009 and 2018, having mentioned that the position to be taken by the respective grantors of the Concession Contract for the National Distribution Network (RND) and the electricity distribution network concessions in BT may determine the revision of this amount. E-Redes did not question the return to the tariff of half of the capital gains generated with the sale of real estate not allocated to any of the activities included in the RND concession and in the concessions of the municipal low voltage electricity distribution networks, having the respective representative on the ERSE Tariff Board voted in favor of this solution. Subsequent to the publication of the Tariffs for 2020, in 17 December 2019, the Government approved an Order that stipulates that the total value of the gains generated by the sale of real estate by E-Redes – Distribuição de Eletricidade, S.A. between 2009 and 2018, and which were subject to remuneration for the tariffs, “reverts entirely to the grantor”, and should be “fully reflected in the electricity tariffs”. On 17 March 2020, E-Redes – Distribuição de Eletricidade, S.A. initiated an arbitration process at the Commercial Arbitration Center, in which claims, moreover, (i) the principle of sharing benefits in this case, may not result in the granting ownership of all the gains generated from the sale of real estate; (ii) that the maintenance of the alienated properties would entail costs for the system, so that their alienation proves to be correct; (iii) that, in relation to all E-Redes real estate where no specific technical installations for each voltage level are installed, as is the case, it is not possible to make any distinction between the respective allocation to the RND concession, or to the municipal concessions for low voltage electricity distribution networks. On 15 December 2020, the Regulator published the tariffs for 2021 and it was considered the return to the system of the remaining amount of 16.6 million Euros referring the net gains obtained from the sale of properties in the period between 2009 and 2018, in accordance with the Dispatch sent by MAAC, despite the ongoing arbitration process. On 25 March 2022, the Arbitration Court issued its decision, which, in summary, results in an interpretation of the Concession Agreement, according to which the income resulting from the sale of the aforementioned real estate and which exceeds the global amount of accumulated depreciation must be recognized as income allowed to the concessionaire. In accordance with the interpretation adopted regarding the RND Concession Agreement, the Arbitration Court decided that the amount of 27.9 million Euros, corresponding to the accumulated depreciation of the real estate transferred between 2009 and 2018, by E-REDES, for a total amount of around 52 million Euros. In view of the finality of this arbitration decision, E-REDES recorded in the first half of 2022 an income of 5.3 million Euros, which will be recovered in the 2023 tariffs and which results from the difference between the amount already returned to the tariffs (33.2 million Euros) and the amount that should have been returned in accordance with the arbitration decision (27.9 million Euros). E-Redes acted in a transparent manner and within the framework of regulatory efficiency standards dictated by ERSE itself, as is evident from the values that have always been evidenced in the published Annual Reports and in the Regulated Accounts presented. Sale of the portfolio of Hydroelectric Projects The project for the sale of the portfolio of Hydroelectric Projects located in the Douro basin falls within the scope of EDP's strategic plan for 2019 2022, as presented to the market in March 2019 and reinforced with EDP's Strategic Plan for 2021-2025 presented in February 2021, in particular within the scope of the strategy of portfolio balancing and capital reallocation, as a way to finance new investments, particularly in renewable energy, including in Portugal. The transaction was concluded on 16 December 2020, through the sale of the entire share capital of the company Camirengia Hidroelétricos S.A. (“Camirengia”), by its sole shareholder, EDP - Energias de Portugal, S.A. ("EDP"), to the company Movhera - Hidroeléctricas do Norte, S.A. (previously known as Águas profundas, S.A., company incorporated in Portugal and therefore resident for tax purposes in Portugal, owned by the consortium formed by GDF International SAS, from ENGIE Group, by 40%, Mirova S.A. by 35% and Predica Prevoyance Dialogue du Credit Agricole, S.A. in 25%). The company Camirengia was incorporated under the simple demerger of EDP - Gestão da Produção de Energia, S.A. ("EDP Produção"), under which a complex set of items was carved-out from this company, comprising not only the titles of use of the hydric resources related to the portfolio mentioned above, but also by a multiplicity of assets, liabilities, resources and contractual positions associated and necessary for the development of the exploration activity. 

Integrated Annual Report 2022 Financial Statements and Notes 261 From a strictly operational, regulatory, technical and legal point of view, the demerger was the only viable and feasible option to proceed with the detachment of the portfolio, considering its size and complexity. In this sense, EDP followed the only model, the demerger and the subsequent sale of shares, that guaranteed the continuity of operations and the maintenance of all the commitments (including environmental nature and towards the municipalities) necessary for the portfolio normal operation and also to respond to the need of the buyer of acquiring a functional and autonomous company that would ensure the operation of all activity, without disruption, immediately after the sale - which was also required by the regulator. On the other hand, the contractual model used in the implementation of the transaction is fully in line with market standards. After its conclusion, the transaction was subject to media attention, based on the assumption that it constitutes a transfer of concessions and that, therefore, would be subject to Stamp Duty (under paragraph 27.2 of the Stamp Duty General Table). In EDP's view, that assumption is not at all applicable, and Stamp Duty is not due, as the transaction did not entail a transfer of concessions, but rather a demerger followed by the sale of the entire share capital of a company (Camirengia) holding the patrimonial assets assigned to the portfolio, operations that are not subject to Stamp Duty. In this context, on 16 March 2021, the President of the EDP Executive Board of Directors was requested to attend the Environment, Energy and Spatial Planning Commission of the Portuguese Parliament, in order to address the abovementioned transaction, where EDP had the opportunity to clarify all questions addressed by the Members present. In addition, on 1 April 2021, that Commission sent EDP a request for information and questions about the transaction. On 15 April, EDP, committed to contribute to the swift, full and definitive clarification of the questions that were presented, sent to the Portuguese Parliament answers to all the questions raised, and made available all the requested documentation, despite its private and confidential nature, as a testament to the collaborative, transparent and good faith attitude with which EDP has been guiding its relationship with the State and its institutions. In this spirit of collaboration, transparency and good faith in its relationship with the State and its institutions, EDP proactively contacted the Tax Authority, making itself available to clarify the tax aspects of the operation. On 6 July 2021, EDP became aware that DCIAP is investigating the sale of the Douro portfolio, with searches carried out at the premises of EDP and EDP Produção. During the diligence, and basing its action on a cooperative posture, all cooperation and assistance was provided to the authorities. EDP scrupulously fulfils all of its obligations, including tax obligations, adopting very strict practices in the technical framework of all issues, having made this transaction under the tax framework applicable, assessing the tax rules in force on the date of the transaction, a framework that was also subject to validation by Opinions requested from reputable tax experts. 5\. Financial risk management policies The military conflict between Russia and Ukraine, which began on 24 February 2022, is having several impacts, namely in the financial markets, due to the volatility it entails, the uncertainty it carries, in a time when Central Banks have been announcing and implementing measures such as the end of asset purchase programs and the hike of interest rates moving away from an accommodative monetary policy which has been in place in the last few years. The Group regularly monitors the financial markets evolution and the market variables to which it has exposure, seeking to mitigate that exposure by maintaining a mix of interest rate with a high percentage of fixed rate, maintaining prudent levels of foreign exchange hedging, choosing carefully its main counterparties favoring high ratings and high levels of liquidity (cash and available credit lines). The Group has adjusted its Financial Risk Management Policies incorporating worst case scenarios sufficiently conservative, therefore adequate to the Group profile. However, given that the duration of the conflict and its global impacts are still unknown, the Group continues to monitor the risks, seeking to anticipate and manage possible additional impacts not currently contemplated. Exchange-rate and interest rate risk management Financial risk management The EDP Group’s business is exposed to a variety of financial risks, including the effect of changes in market prices, foreign exchange and interest rates. The Group’s exposure to financial risks arises essentially from its debt portfolio, its investments and from the volatility of commodity prices, resulting in interest and exchange rate exposures as well as commodity market price exposure. The status and evolution of the financial markets are analysed on an on-going basis in accordance with the Group’s risk management policy. The management of financial risks of EDP, S.A. and other EDP Group entities is undertaken centrally by EDP, S.A., in accordance with policies approved by the Executive Board of Directors. The Financial, the Energy Management and the Risk Management Departments identify, evaluate and submit to the Board, for approval, hedging mechanisms appropriate to each exposure. The Executive Board of Directors is responsible for the definition of general risk management principles and the establishment of exposure limits. 

Integrated Annual Report 2022 Financial Statements and Notes 262 As for the subsidiaries of EDP Energias do Brasil, the management of the financial risks inherent to the variation of interest rates, exchange rates and commodities is carried out locally, according to the rules set by EDP Energias do Brasil's Management and aligned with the principles/policies set by EDP Group for this geographical area. Exchange-rate risk management EDP Group operates in different geographies, therefore becoming exposed to exchange rate risk in US Dollar (USD), Brazilian Real (BRL), Polish Zloty (PLN), Romanian Leu (RON), Canadian Dollar (CAD), Pound Sterling (GBP), Hungarian Forint (HUF), Colombian Pesos (COP), Singapore Dollar (SGD) and other asian currencies. Currently, these exposures result essentially from investments of EDP Group in wind parks (and solar) in the USA, Poland, Romania, Canada, United Kingdom, Hungary, Colombia and Singapore. The exposure to Brazilian Real results essentially from investments of EDP Group in EDP Energias do Brasil and EDP Renováveis Brasil. The majority of these investments were financed with debt contracted in the respective local currency which allows to mitigate the exchange rate risk related to these assets, and such financing is complemented, in certain cases, with derivatives to hedge exchange-rate risk on net investment. The policy implemented by the EDP Group consists of undertaking derivative financial instruments to hedge exchange rate risk with similar terms to those of the hedged asset or liability. The operations are revalued and monitored throughout their useful lives and, periodically, their effectiveness in controlling and hedging the risk that gave rise to them is assessed. Investments in the Brazilian subsidiaries of EDP Energias do Brasil, whose net assets expressed in Brazilian Real expose EDP Group to the exchange rate risk from its conversion to Euros, are monitored through analysis of the evolution of the BRL/EUR exchange rate. In the hedge relationships, the main source of ineffectiveness is the effect of the counterparties’ and the Group’s own credit risk on the fair value of the forward foreign exchange contracts and cross currency interest rate swaps, which is not reflected in the change in the fair value of the hedged cash flows attributable to the change in exchange rates. Sensitivity analysis - exchange rate Regarding the financial instruments that result in an exchange rate risk exposure, a fluctuation of 10% in the EUR/USD exchange rate, as at 31 December 2022 and 2021, would lead to an increase/(decrease) in the EDP Group results and/or equity as follows: Thousand Euros Dec 2022 Profit or loss Equity +10% -10% +10% -10% USD 9,696 -11,851 -65,279 79,785 Thousand Euros Dec 2021 Profit or loss Equity +10% -10% +10% -10% USD -14,282 17,456 -64,579 78,930 This analysis assumes that all other variables, namely interest rates, remain unchanged. Interest rate risk management The aim of the interest rate risk management policies is to manage the impact on financial charges, from contracted debt, related to the exposure to interest rate risk from market fluctuations. In the floating rate financing context, the EDP Group enters, when considered appropriate, into interest rate derivative financial instruments to hedge the cash flows associated with future interest payments, which have the effect of converting floating interest rate loans into fixed interest rate loans. Long-term debt engaged at fixed rates is, when appropriate, converted into floating rate debt through interest rate derivative financial instruments designed to level them to current and expected market conditions. All the operations are undertaken on liabilities in the EDP Group’s debt portfolio and mainly involve perfect hedges, resulting in a high level of correlation between changes in fair value of the hedging instrument and changes in fair value of the interest rate risk or future cash flows. In the hedge relationships, the main source of ineffectiveness is the effect of the counterparty’s and the Group’s own credit risk on the fair value of the interest rate swaps, which is not reflected in the change in the fair value of the hedged cash flows attributable to the change in interest rates. 

Integrated Annual Report 2022 Financial Statements and Notes 263 The EDP Group has a portfolio of interest rate derivatives with maturities up to 17 years. The Group’s Financial Department undertakes sensitivity analyses of the fair value of financial instruments to interest rate fluctuations. As at 31 December 2022, after the hedging effect of the derivatives 75% of the Group's liabilities are at fixed rate. During 2022, the EDP Group also entered into forward-starting interest rate swaps, in EUR and USD, in order to pre-hedge its exposure to the risk of interest rates increasing until the expected refinancing date of its outstanding debt, for the next 2 years. Sensitivity analysis - Interest rates (excluding the Brazilian operations) Based on the Group's debt portfolio, except for Brazil, and the related derivative financial instruments used to hedge the related interest rate risk, a 100 basis points change in the reference interest rates at 31 December 2022 and 2021 would lead to an increase/(decrease) in the EDP Group results and/or equity as follows: Thousand Euros Dec 2022 Profit or loss Equity 100 bp increase 100 bp decrease 100 bp Increase 100 bp decrease Cash flow effect: Hedged debt -10,103 10,103 \- \- Unhedged debt -8,844 8,844 \- \- Fair value effect: Cash flow hedging derivatives \- \- 11,268 -11,268 Trading derivatives (accounting perspective) 68 -68 \- \- -18,879 18,879 11,268 -11,268 Cash flow effect: Hedged debt -18,682 18,682 \- \- Unhedged debt -2 2 \- \- Fair value effect: Cash flow hedging derivatives \- \- 12,848 -12,848 Trading derivatives (accounting perspective) 5,501 -5,501 \- \- -13,183 13,183 12,848 -12,848 This analysis assumes that all other variables, namely exchange rates, remain unchanged. Brazil - Exchange and interest rate risk management Stress tests and sensitivity analysis are carried out for purposes of risk management in the Brazilian subsidiaries. Through these two tools, the financial impact in different market scenarios is monitored. For sensitivity analysis, the exposure of portfolio of operations is evaluated through 25% and 50% changes in the main risk factors, currency and interest rates, and the scenario with the highest probability of occurrence is presented (25%). The stress test is performed on the fair value of the operations and uses as premise the interest rate curve projections of the Brazilian basic macroeconomic scenario. Brazil - Sensitivity analysis - exchange rate Three Brazilian subsidiaries are mainly exposed to the USD/BRL exchange rate, arising from USD debt for which the exposure is completely offset by cross currency interest rate swaps. Brazil - Sensitivity analysis - Interest rates Based on the portfolio of operations, a 25% change in the interest rates, to which the Brazilian subsidiaries are exposed to, would have an impact to EDP Energias do Brasil Group in the amount of: Thousand Euros Dec 2022 Dec 2021 \+ 25% \- 25% \+ 25% \- 25% Financial instruments – assets 24,881 -24,499 11,328 -10,913 Financial instruments – liabilities -105,539 117,991 -110,495 109,851 Derivative financial instruments -2,686 9,352 -7,580 8,137 -83,344 102,844 -106,747 107,075 Thousand Euros Dec 2021 Profit or loss Equity 100 bp 100 bp increase decrease 100 bp increase 100 bp decrease 

Integrated Annual Report 2022 Financial Statements and Notes 264 Counterparty credit risk management EDP Group’s policy in terms of counterparty risk on financial transactions (see note 2 e)) is managed through an analysis of the technical capacity, competitiveness, credit rating and exposure to each counterparty, avoiding significant concentrations of credit risk. Counterparties in derivative financial instruments are institutions with high credit rating so the risk of counterparty default is not considered to be significant. Therefore, guarantees and other collaterals are not typically required for these transactions. EDP Group has documented its financial operations in accordance with international standards. Derivative financial instruments are mainly contracted under ISDA Master Agreements. The amount receivable from customers is mainly generated by operations in Portugal, Spain and Brazil, with a diversified customer base, both geographically and in terms of segments (business clients, private and public sector) and size (Supply companies, Business to Business (B2B) and Business to Consumer (B2C)). EDP is present in several countries and continents, structured in 4 regional hubs: Europe, Asia-Pacific, North America and South America. It has more than 8.5 million customers in the electricity sector and 0.6 million customers in the gas sector, and usually the contractual relationship with the counterparty tends to be long-lasting. The maximum exposure to customer credit risk by counterparty type is detailed as follows: Thousand Euros Dec 2022 Dec 2021 Corporate and private sector: Supply companies 200 81,366 B2B 496,804 443,937 B2C 425,163 354,586 Other Public sector: Debt with payment agreement 556,939 652,790 1,479,106 1,532,679 1,375 4,059 Debt without payment agreement 160,197 202,896 161,572 206,955 1,640,678 1,739,634 Trade receivables by geographical market for the Group EDP, is as follows: Thousand Euros Dec 2022 Portugal Spain Brazil USA Other Group Corporate and private sector 669,995 315,698 374,164 27,248 92,001 1,479,106 Public sector 34,223 112,988 13,909 \- 452 161,572 704,218 428,686 388,073 27,248 92,453 1,640,678 Corporate and private sector 860,518 281,042 350,076 22,287 18,756 1,532,679 Public sector 38,780 149,831 18,034 \- 310 206,955 899,298 430,873 368,110 22,287 19,066 1,739,634 The amounts receivable from supply companies are concentrated mainly in Portugal, Brazil and EDP Renováveis Group, as follows: \- In Portugal, these counterparties present a significantly reduced days sales outstanding, about 20 days, and these entities are subject to the sector regulation that establishes collaterals to reduce credit risk. The collateral provided is updated based on the average of the last quarter monthly sales, which reinforces a low risk profile; \- In Brazil, it refers mainly to: (i) the amounts from sale of electricity to wholesale dealers and supply companies, (ii) accounts receivable relating to energy traded in the Electric Energy Trading Chamber - CCEE; and (iii) charges for the electricity network access; \- In EDPR EU (Europe) & Latin America platform, main customers are utilities and regulated entities in the different countries. Credit risk is not significant due to the limited average collection period for customer balances and the quality of its debtors. Additional counter-party risk comes from the countries with renewables incentives, which it is usually treated as regulatory risk; \- In EDPR NA (North America) platform, main customers are regulated utility companies and regional market agents in the US. As it occurs in Europe, credit risk is not significant due to the limited average collection period for customer balances and the quality of the debtors. However, the exposure due to the mark-to-market of long term contracts may be significant; and \- In EDPR APAC (Asia-Pacific) platform, the Group’s main customers are Distributed Generation offtakers and regulated entities in the different markets, namely in Singapore and Vietnam. As it occurs in the other platforms, credit risk from trade receivables is not significant due to same reasons. However, counter-party risk comes from countries with renewables incentives through regulated tariffs, which it is usually treated as regulatory risk. Thousand Euros Dec 2021 Portugal Spain Brazil USA Other Group 

Integrated Annual Report 2022 Financial Statements and Notes 265 Exposure in all markets EDPR operates is managed by a detailed assessment of the counter-party before signing any long term agreement and by a requirement of collaterals when financial soundness of the counterparty deteriorates. Regarding the remaining receivables from companies and individual customers, resulting from the current activity of EDP Group, the credit risk is essentially the result of customers defaults, whose exposure is limited to the supply made until the possible date of supply disruption. A very criterious credit risk analysis made for new costumers, as well as the large number of customers and their diversity in terms of sectors of activity are some of the main factors that mitigate the concentration of counterparty credit risk. Amounts receivable from public sector customers include amounts receivable from renegotiated debt with payment agreements, which, as the counterparty is a public entity and has already recognised the debt through payment protocols, present a lower risk. These amounts also include debt without payment agreements arising from the normal power supply activity similar to that described for the corporate and individual sector. In accordance with accounting policies - note 2 e), impairment losses are determined using the simplified approach precluded in IFRS 9, based on life time expected losses. Regarding third-party receivables generated by the Group’s day-to-day business, the credit risk arises essentially from customers default, whose exposure is limited to the Low Tension Electricity supplied with usual delays in payments. The very criterious credit risk analysis made for new costumers, as well as the large number of customers and their diversity in terms of sectors of activity are some of the main factors that mitigate the concentration of counterparty credit risk. EDP Group believes that the amount that best represents the Group's exposure to credit risk corresponds to the carrying amount of customers and of Contract assets related to energy sales net of the impairment losses recognised. The Group believes that the credit quality of these receivables is adequate and that no significant impaired credits exist that have not been recognised as such and provided for. As at 31 December 2022, in accordance with the methodology for determining impairment losses on amounts receivable from the electric sector, no impairment loss has been booked. The risk levels for amounts receivable from the electric sector have been considered to be the same as the country risk levels for Brazil, Portugal and Spain, which have high credit ratings. The maximum exposure to credit risk of Contract assets related to energy sales and Amounts receivable from the electric sector is as follows: Thousand Euros Dec 2022 Dec 2021 Contract assets related to energy sales: Contract assets receivable from energy sales contracts 1,449,960 1,727,613 Amounts receivable from the electric sector: Amounts receivable from tariff adjustments - Electricity (see note 26) 1,449,960 1,727,613 483,217 860,661 Amounts receivable relating to CMEC (see note 26) 603,475 657,734 Amounts receivable from concessions - IFRIC 12 (see note 26) 1,966,939 1,208,888 3,053,631 2,727,283 4,503,591 4,454,896 Liquidity risk management The EDP Group undertakes management of liquidity risk through the engagement and maintenance of credit lines and financing facilities, with a firm underwriting commitment with international reliable financial institutions, as well as term deposits, allowing immediate access to funds. These credit lines are used to complement and backup national and international commercial paper programmes, allowing the EDP Group’s short-term financing sources to be diversified (see note 34).

Energy market risk management Energy market risk management (excluding the Brazilian operations) In the sphere of its operations in the Iberian market for both electricity and gas, EDP Group purchases fossil fuels to generate electric energy which is sold in organized markets (OMIE and OMIP) as well as to third parties or, in the gas business, sells natural gas to clients either through EDP Group’s trading companies or directly to third parties. As a result, the Group is fully exposed to energy market risks. As a result of its energy management operations, EDP Group has a portfolio of operations related to electricity and gas businesses. The portfolio is managed through the engagement of operations with financial and physical settlement on the forward energy markets. The objective of the operations is to reduce volatility of the financial impact resulting from the managed positions and to benefit from arbitration or positioning within the trading limits approved by the Executive Board of Directors. The financial instruments traded include swaps (electricity, coal and gas) and futures to fix prices. In the hedge relationships, the main source of ineffectiveness is the effect of the counterparty’s and the Group’s own credit risk on the fair value of the derivative financial derivatives, which is not reflected in the change in the fair value of the hedged cash flows attributable to the change in market prices. Energy management activity is subject to a series of variables which are identified and classified based on their common uncertainty characteristics (or risk). Such risks include market price evolution risk (electricity and fuel) with impact in the expected energy volume generated, as well as credit risk of the counterparties. Monitoring the price, volume and credit risks includes their quantification in terms of positions at risk which can be adjusted through market operations. This quantification is made by using specific models that value positions to determine the maximum loss that can be incurred, with a given probability and a determined time frame. Risks are managed in accordance with the strategies defined by the Executive Board of Directors, which are subject to a periodic review based on the evolution of the operations, to change the profile of the positions and adjust them to the established management objectives. Risks are monitored by means of a series of actions involving daily monitoring of the different risk indicators, of the operations grouped in the systems and the prudence limits defined by management area and risk component, as well as regular backtesting and supplementary validation of the models and assumptions used. This monitoring not only ensures the effectiveness of the strategies implemented, but also provides elements to enable initiatives to be taken to correct them, if necessary. 

Integrated Annual Report 2022 Financial Statements and Notes 267 The main price and volume risk indicator used is the margin at risk (P@R), which estimates the impact of the variation of the different risk factors (price of electricity and hydrological) on the next 24 month’s margin, P@R corresponding to the difference between an expected margin and a margin of a pessimistic scenario with a probability to occur of 5% (confidence interval of 95%) considering a time frame of 2 months. Both the volumes which are certain and those, which although uncertain, are expected, namely production of the plants and the corresponding consumption of fuel, are considered. The P@R distribution by business segment is as follows: Thousand Euros P@R Distribution by business segment Dec 2022 Dec 2021 Business Electricity Portfolio Trading 50,483 2,391 Electricity Trading \+ Hedging 342,309 369,883 Gas Hedging 120,588 77,363 Diversification effect -93,380 -17,505 420,000 432,131 Regarding credit risk, the quantification of exposure considers the amount and type of transaction (e.g. swap or forward), the rating of the counterparty risk that depends on the probability of default and the expected value of credit to recover, which varies depending on the guarantees received or the existence of netting agreements. The EDP Group's exposure to credit risk rating is as follows: Dec 2022 Dec 2021 Credit risk rating (S&P) A+ to A- 22.45% 47.53% BBB+ to BBB- 49.88% 34.70% No rating assigned 27.67% 17.77% 100.00% 100.00% Brazil - Energy market risk management Arising from the energy trading activity in Brazil, EDP Trading Comercialização e Serviços de Energia, S.A. and EDP Smart Energia Lda. are exposed to market price risk associated with future commitments, resulting from bilateral contracts for the purchase and sale of energy. At reporting date, the result of future commitment contracts is determined as the differential, for each maturity term, between the prices of the bilateral contracts for the purchase and sale of energy and their mark-to-market valuation using forward price curves. The result of future commitment contracts presents volatility associated with energy price fluctuation, generating market price risk. The management of market price risk is carried out through the determination and daily monitoring of the risk respecting the limits approved by the Management of EDP Brazil, and framed within the Risk Management Policy of the EDP Group, for the purchase and sale of energy using a methodology established in the Energy Risk Policy. The methodology adopted is a VaR (Value at Risk) with 95% confidence that considers a forward curve of market prices, the exposure of the portfolio (difference between purchase and sell) and the volatility and liquidity observed in the free market for each period. For sensitivity analysis, the exposure of portfolio of operations is evaluated through 25% and 50% changes in the forward curve of market energy prices. Below shows the scenario with the highest probability of occurrence (25%).

Therefore, capital management is carried out within the financial risk management process of the entity. Additionally, management describes this aspect of its strategic objectives, policies and processes to manage risks, including the financial risks, in the chapters of the Annual Report of 2022: Part I - 02 Strategic Approach 2.3 Risk Management: Key Risks - Financial; Risk Appetite - Financial; and 2.4.Strategic Guidelines Compliance - Sustainable Financial Leveraging.

Integrated Annual Report 2022 Financial Statements and Notes 268 The Group’s goal in managing capital is to safeguard the Group’s capacity to continue operating as a going concern, grow steadily to meet established objectives and maintain an optimum capital structure to reduce equity cost. In conformity with other groups operating in this sector, the Group controls its financing structure based on several control mechanisms and ratios. 6\.

Integrated Annual Report 2022 Financial Statements and Notes 276 11\. Other expenses Other Expenses are as follows: Thousand Euros Group Dec 2022 Dec 2021* Concession rents paid to local authorities and others 286,968 281,209 Direct and indirect taxes 374,965 300,326 Donations 21,570 21,219 Write-off of tangible assets 40,591 31,195 Other 105,630 94,016 829,724 727,965 * Includes restatement originated by changing the classification of the Social Tariff Costs as described in note 2a) The caption Concession rents paid to local authorities and others includes essentially the rents paid to the local authorities under the terms of the low tension electricity distribution concession contracts and rents paid to city councils where the power plants are located. The increase in the caption Direct and indirect taxes essentially results from the new taxes on generation in Spain, as a result of the legislation issued in September 2021 to reduce the impact of the high price of gas on the sale price of generation and the regulatory changes in Spain regard to the Social Tariff in 2022 and in Romania and Poland regarding to Windfall taxes in 2022. The caption "Write-off" of tangible fixed assets includes, essentially, the write-off of tangible fixed assets resulting from losses in materials and equipment in Brasil and the abandonment of the renewable projects in Europe and North America.

Amortisation and impairment Amortisation and impairment are as follows: Thousand Euros Group Company Dec 2022 Dec 2021 Dec 2022 Dec 2021 Depreciation/impairment of Property, plant and equipment (see note 16) 1,371,272 1,214,239 6,156 5,519 Depreciation/impairment of Right of use asset (see note 17) 113,380 77,640 5,219 5,661 Amortisation/impairment of Intangible assets (see note 18) 514,968 449,362 19,359 16,673 Amortisation/impairment of Investment property (see note 23) 1,999,620 1,741,241 30,734 27,853 289 297 4,225 3,796 Compensation of depreciation Partially-funded property, plant and equipment (see note 38) 1,999,909 1,741,538 34,959 31,649 -28,579 -22,517 \- \- Amortisation of Incremental costs of obtaining contracts with customers 7,677 7,747 \- \- Impairment of Goodwill (see note 19) \- 4,987 \- \- 1,979,007 1,731,755 34,959 31,649 During 2022, due to the revision of market assumptions (in mainly, commodity prices and energy sales prices), as well as the entry of renewable energy capacity, the Group carried out a review of its future estimates of value by carrying out impairment tests for some of the production assets. The above impairment tests carried out led to the recording of the following impairments on assets in Portugal: 81,740 thousand Euros in the Lares combined cycle thermoelectric power plant and 43,666 thousand Euros in the Ribatejo combined cycle thermoelectric power plant. Impairments were also recorded in Brazil at the Pecém plant (233,125 thousand Euros) and in Colombia at the wind farms of Eolos Energia and Ventos de Norte (54,088 thousand Euros) (see notes 16 and 18). In the scope of impairment tests on these assets, sensitivity analyzes were performed on key variables, namely discount rates. An increase of +0.5% in the discount rate would determine an additional impairment of approximately: 8,579 thousand Euros in Lares, 10,668 thousand Euros in Ribatejo, 7,643 thousand Euros in Pecém and 49,776 thousand Euros in Eolos Energia wind farms and Ventos del Norte in Colombia. 

Integrated Annual Report 2022 Financial Statements and Notes 277 Additionally, given the changes in market conditions, impairments amounting to 39,305 thousand in the coal-fired power plant in Espanhã Aboño 2 and 40,976 thousand in the coal-fired power plant in Soto3 were reversed (see note 16). 13\. Financial income and expenses Financial income and expenses, for the Group, are as follows: Thousand Euros Group Dec 2022 Dec 2021 Financial income Interest income from bank deposits and other investments 80,689 15,097 Interest from derivative financial instruments 33,600 16,558 Interest income on tariff deficit: \- Portugal - Electricity (see note 26) 111 2,733 \- Brazil - Electricity (see note 38) 16,664 6,057 Other interest income 65,002 53,476 Derivative financial instruments 223,328 53,936 Foreign exchange gains 353,572 100,746 CMEC: \- Interest on the initial CMEC 23,950 27,336 \- Financial effect considered in the calculation 7,147 7,198 Other financial income 38,937 81,746 Financial expenses Interest expense on financial debt 843,000 364,883 705,812 523,928 Bonds buyback \- 24,248 Capitalised borrowing costs: \- Assigned to concessions (see note 7) -4,442 -57,816 \- Other (see note 16) -41,405 -33,086 Interest from derivative financial instruments 134,765 33,411 Interest expense on tariff deficit: \- Portugal - Electricity (see note 38) 4,484 53 \- Brazil - Electricity (see note 38) 16,079 3,989 Other interest expense 40,063 22,435 Derivative financial instruments 259,167 106 Foreign exchange losses 356,958 126,165 CMEC 5,231 7,681 Unwinding of discounted liabilities 140,955 123,248 Unwinding of lease liabilities (see note 39) 46,146 39,511 Net interest on the net pensions plan liability (see note 35) 5,132 3,300 Net interest on the medical liabilities and other benefits (see note 35) 14,985 13,290 Other financial expenses 69,290 45,353 Financial income/(expenses) 1,753,220 875,816 -910,220 -510,933 Capitalised borrowing costs includes the interest capitalised in assets under construction according to Group accounting policy (see note 2 h)). Regarding the rate applicable to borrowing costs related with tangible/intangible assets under construction that is used in the determination of the amount of borrowing costs eligible for capitalisation (see notes 16 and 18), it varies depending on business unit, the country and currency, since EDP Group incorporates in its scope of consolidation a significant number of subsidiaries in several geographies with different currencies. Therefore, for the most representative geographies, the weighted average funding rates, in use in 2022, ranged from 1.22% to 6.66% in Portugal, from 1.05% to 6.79% in Spain and from 0.44% to 7.75% in North America, depending on related assets under construction and related financing. The costs related to the Unwinding liabilities at discounted value refer essentially to: (i) the financial update of the provision for dismantling and decommissioning of production assets in the amount of 6,609 thousand Euros (31 December 2021: 3,753 thousand Euros) (see note 36); (ii) the implied financial return in institutional partnerships of 96,955 thousand Euros (31 December 2021: 79,023 thousand Euros) (see note 37); and (iii) the financial expenses related to the discount of the liability associated to the concessions of Alqueva/Pedrógão, Investco and Enerpeixe of 20,700 thousand Euros (31 December 2021: 26,256 thousand Euros). The Derivative financial instruments caption includes income and expenses related with financial assets and liabilities measured and fair value through profit and loss, while the remaining captions of financial income and expenses are registered at amortised cost, based on the effective interest rate method. 

Integrated Annual Report 2022 Financial Statements and Notes 278 In the third quarter of 2021, under the agreement entered into with Sonatrach with a view to ending commercial relations between the companies, it was agreed a debt cancellation that EDP had with Sonatrach companies in the amount of 79 million of Euros for a payment of 15 million Euros. The impact of this operation is included in the Caption Other Financial Income. Financial income and expenses, for the Company, are as follows: Thousand Euros Company Dec 2022 Dec 2021 Financial income Interest income from loans to subsidiaries and related parties (see note 44) 35,873 37,906 Interest from derivative financial instruments 106,745 81,127 Derivative financial instruments 444,047 164,763 Income from equity investments (see note 44) 1,003,733 1,164,310 Other financial income 60,030 11,210 Financial expenses Interest expense on financial debt 1,650,428 1,459,316 194,411 195,422 Bonds Buyback 17,882 16,525 Interest from derivative financial instruments 119,570 102,457 Derivative financial instruments 425,300 136,176 Unwinding of lease liabilities 5,874 4,949 Impairment on equity investments and shareholders loans (see note 20) 26,630 \- Other financial expenses 69,058 19,010 Financial income/(expenses) 858,725 474,539 791,703 984,777 On March 2022, EDP S.A. has bought an amount of 900 million Euros from the issue "EUR1.500.000.000 Fixed Rate Notes due Dec 2022", booking a cost related to the transaction of 17,882 thousand Euros. On December 2021, EDP S.A. has bought an amount of 150 million Euros from the issue "EUR1.000.000.000 Fixed Rate Notes due 2025", booking a cost related to the transaction of 16,525 thousand Euros. The caption Other financial income includes 14,911 thousand Euros related to nominal interests from bonds issued by EDP Finance B.V., repurchased by EDP S.A. (see notes 27 and 44). The effective interest of these instruments amounts to 1,111 thousand Euros (includes the recognition of premium and transaction costs associated with the buyback transaction by the effective interest rate method). The fluctuation on Other financial income and expenses, on an individual basis, is mainly explained by the impact of the foreign exchange of the American Dollars. 14\. Income tax The following note includes an analysis on the reconciliation between the theoretical and the effective income tax rate applicable at an individual level and at the level of the EDP Group, on a consolidated basis. In general terms, this analysis aims to quantify the impact of the income tax, recognised in the income statement, which includes both current and deferred tax. As the EDP Group prepares and discloses its financial statements in accordance with IFRS, an alignment between the accounting of income tax expense or income and the corresponding cash flow is not mandatory. Accordingly, this analysis does not represent the income tax paid or received by the EDP Group for the correspondent reporting period. The overall tax contribution borne by the EDP Group (which includes comments on the contributions paid to the respective states where the Group operates), as well as other relevant information (such as EDP Group's tax footprint, specific taxation over energy sector and procedures to control and manage adverse tax exposures), are disclosed on the annual Integrated Report, available on EDP website (www.edp.com). The general principles concerning EDP Group's mission and tax policy are also addressed in the same report. This document also describes the key principles with respect to transfer pricing policy applicable to the EDP Group, under which the Group's policy is to abide within the international rules, guidelines and best practices applicable in the various geographies where it operates. It should be noted that, as a multinational group, the EDP Group fully complies with the annual obligation of communication and report, which results from the transposition to the Portuguese domestic Law of the disposals of Action 13 of the Base Erosion and Profit Shifting (named Country-by-Country Reporting), as a part of a set of measures adopted by OECED and G20 countries to enhance transparency for tax administrations. Furthermore, this obligation is fulfilled in Portugal by the parent company, within the deadlines foreseen by law. 

Integrated Annual Report 2022 Financial Statements and Notes 279 Main features of the tax systems of the countries in which EDP Group operates The statutory corporate income tax rates applicable in the main countries in which EDP Group operates are as follows: Dec 2022 Dec 2021 Europe: Portugal 21% - 31,5% 21% - 31,5% Spain 24% - 25% 24% - 25% Netherlands 25.8% 25% Belgium 25% 25% France 25% 26,5% - 27.5% Italy 24% - 28,8% 24% - 28,8% Poland 19% 19% Romania 16% 16% United Kingdom 19% 19% Asia Singapore 17% 17% Vietnam 20% 20% America: Brazil 34% 34% United States of America 24.91% 24.91% Canada 26.5% 26.5% Mexico 30% 30% EDP Group companies are taxed, whenever possible, on a Group consolidated basis as allowed by the tax legislation of the respective countries. As per the applicable legislation, in general terms, tax periods may be subject to review and reassessment by the various tax authorities during a limited number of years. Statutes of limitation differ from country to country, as follows: Portugal 4 years or, if tax losses or credits have been used, the number of years that such tax losses or credits may be carried forward; Spain 4 years; USA and The Netherlands 3 years; and Brazil 5 years. In the remaining main jurisdictions, the deadline for review and reassessment by the various tax authorities ranges between 3 and 10 years. Tax losses generated in each year are also subject to tax authorities' review and reassessment and may be used to offset yearly taxable income assessed in the subsequent periods, in the main jurisdictions in which EDP is present, as follows: in Portugal 5 years (for tax losses of 2017 to 2019 and 2022, not being considered the years 2020 and 2021 for the purposes of this period); and 12 years (for tax losses of 2014 to 2016, the years 2020 and 2021 are also not considered for the purposes of this count), and a reduction in the annual deduction limit as a percentage of taxable income without term in the Netherlands, Spain, USA and Braziland. From 2023 onwards, in Portugal, there is no longer a time limit for reporting tax losses (including those whose reporting period is in progress on 1 January 2023). Moreover, in the Netherlands the tax losses of a given year may be used to recover current tax of the previous year with limitations. However, the deduction of tax losses in Portugal, Spain, Netherlands, USA and Brazil may be limited to a percentage of the taxable income of each period or is subject to other limitations. EDP Group companies may, in accordance with the law, benefit from certain tax benefits or incentives in specific conditions, namely the Production Tax Credit in North America, which are the dominant form of wind remuneration in this country, and represent an extra source of revenue per unit of electricity, over the first 10 years of the asset’s life. Wind facilities that qualify for the application of the Production Tax Credits prior to 1 January 2017, benefit from 100% of the credit ($25/MWh in 2020 and in 2021, being adjusted to inflation in subsequent years). The credit amount is reduced by 20% for wind facilities qualifying in 2017, 40% in 2018 and 60% in 2019. Additional legislation in 2020 and 2021 extended the aforementioned regime to wind facilities, with start of construction in 2020 or 2021, attributing 60% of the tax credit amount. Additionally, EDP Group companies benefit from the Investment Tax Credit which avails solar projects to a credit based upon its capital expenditures. This credit amount equates to 26% for projects that start construction before 2022 and 22% for projects starting construction in 2023 as long as these projects go into service by 2025. Relevant events for EDP Group with impact in 2022 During the course of 2021 and 2022 several European countries enacted the so called windfall taxes. In what concerns to EDP Group, as of 31 December 2022, these taxes mainly impact Romania, Poland and Italy. 

Integrated Annual Report 2022 Financial Statements and Notes 280 In this context, governments in Romania and Poland have recently introduced emergency clawback mechanisms to restrict the revenues earned by renewable energy producers and other market participants. In Romania, a 100% tax is applied on revenues over 450 RON/MWh as well as a withholding tax on behalf of offtakers. In Poland, the clawback mechanism consists in a 100% tax on revenues above 345 PLN/MWh for wind projects under Green Certificate (GC) scheme and the corresponding strike price for projects under CfD scheme. Lastly, during 2022 was approved in Italy a retroactive increase of the windfall tax to 50% (previously set at 25%) that applied in 2022 to the portion of total income determined for corporate income tax purposes that exceeds by, at least, 10% of the average total income determined for corporate income tax purposes earned in the periods between 2018 and 2021 by producers and sellers of electricity, natural gas and petrol products. The amount of this extraordinary contribution shall not exceed 25% of the equity value of the assets at the end of 2021. The European Union Council Regulation 2022/1854 of 6 October 2022 consubstantiated on a European Union wide emergency intervention to address high energy prices. While EDP Group fully acknowledges that the existing emergency situation required for extraordinary measures, the Group also considers that (i) the principle of not taxing unrealized extra-profits should always prevail and (ii) the compatibility with existing, legitimately implemented, risk management strategies, needs to be ensured. These requirements are necessary to avoid harming producers that do not actually benefit from the current high electricity prices, due to having hedged, individually or at Group level, their revenues, against fluctuations in the wholesale electricity market. These financial hedges follow the Group’s established low risk strategy to secure long term revenues and to remove electricity prices volatility on the Group’s earnings. EDP will pursue all legal actions at its disposal in order to challenge the legality of these measures. Corporate income tax provision Income tax expense is as follows: Thousand Euros Group Company Dec 2022 Dec 2021 Dec 2022 Dec 2021 Current tax -374,432 -191,433 22,068 38,028 Deferred tax -24,058 -70,459 35,602 20,456 -398,490 -261,892 57,670 58,484 Reconciliation between the theoretical and the effective income tax expense The effective income tax rate is as follows: Thousand Euros Group Company Dec 2022 Dec 2021 Dec 2022 Dec 2021 Profit before tax and CESE 1,619,773 1,419,852 790,895 765,586 Income tax expense -398,490 -261,892 57,670 58,484 Effective income tax rate 24.6% 18.4% -7.3% -7.6% The difference between the theoretical and the effective income tax expense results from the application of the law provisions, in the various countries where EDP operates, in the determination of the taxable base, as demonstrated below. The reconciliation between the theoretical and the effective income tax expense for the Group, in December 2022 and 2021, is as follows: Thousand Euros Dec 2022 Dec 2021 Profit before income tax and CESE 1,619,773 1,419,852 Theoretical income tax rate * 29.5% 29.5% Theoretical income tax expense 477,833 418,856 Different tax rates (includes state surcharge) and CIT rate changes 5,212 -74,081 Tax losses and tax credits -97,364 14,579 Dividends -22,179 -15,327 Tax benefits -16,520 -21,686 Differences between accounting and fiscal provisions/depreciations 80,891 11,062 Accounting/fiscal differences on the recognition/derecognition of assets 7,634 -69,764 Taxable differences attributable to non-controlling interests -18,870 -16,576 Other adjustments and changes in estimates -18,147 14,829 Effective income tax expense as per the Consolidated Income Statement 398,490 261,892 * Average tax rate considering the different tax rates applicable to EDP Group companies in Portugal.

Integrated Annual Report 2022 Financial Statements and Notes 281 The caption Accounting/fiscal differences on the recognition/derecognition of assets mainly includes the impacts inherent to transactions of production and energy supply business assets, in the several geographies in which the Group operates as a result of its business activity (see note 6). The caption Different tax rates (includes state surcharge) and CIT rate changes mainly refer to the difference between the tax rates applicable in the countries in which the EDP Group operates as compared to the tax rate used as reference for the theoretical income tax expense calculation. The caption Taxable differences attributable to non-controlling interests (North America) include the effect inherent in the attribution of taxable income to non-controllable interests in EDPR Group in the USA, as determined by the tax legislation of that geography. The reconciliation between the theoretical and the effective income tax expense for the Company, in 2022 and 2021, is as follows: Thousand Euros Dec 2022 Dec 2021 Profit before income tax 790,895 765,586 Nominal income tax rate 21% 22,5%* Theoretical income tax expense 166,088 172,257 Tax losses and tax credits -11,329 26,461 Dividends -209,151 -261,970 Accounting/fiscal temporary differences on the recognition / derecognition of assets -9,780 \- Other adjustments and changes in estimates 6,502 4,768 Effective income tax expense as per the Company Income Statement -57,670 -58,484 * Statutory Corporate Income Tax rate applicable in Portugal (21%) and municipal surcharge (1.5%), 15\. Extraordinary contribution to the energy sector (CESE) Law 83-C/2013, of the State Budget 2014 ("Lei do Orçamento de Estado 2014"), approved by the Portuguese Government on 31 December 2013, introduced CESE, with the objective of financing mechanisms that promote the energy sector systemic sustainability, through the establishment of a fund which aims to contribute for the reduction of tariff debt and to finance social and environmental policies in the energy sector. This contribution focuses generally on the economic operators that develop the following activities: (i) generation, transmission or distribution of electricity; (ii) transportation, distribution, storage or wholesale supply of natural gas; and (iii) refining, treatment, storage, transportation, distribution and wholesale supply of crude oil and oil products. CESE is calculated based on the companies’ net assets as at 1 January, which comply, cumulatively, to: (i) property, plant and equipment; (ii) intangible assets, except industrial property elements; and (iii) financial assets assigned to concessions or licensed activities. In the case of regulated activities, CESE focuses on the value of regulated assets if it is higher than the value of those assets. The general rate is 0.85%. However, in case of natural gas combined cycle power plants with an annual utilization equivalent of installed capacity equal or higher to 1,500 hours and lower than 3,000 hours, is expected a reduced rate of 0.565%. Nevertheless, this rate could be 0.285% in case the annual utilization of installed capacity is lower than 1,500 hours. The CESE system has been successively extended and is now valid for 2022 through Law nº 99/2021 of 31 December. EDP has paid 558,205 thousand Euros relating to CESE so far.

Client Solutions & Energy Management The increase in goodwill is related with the acquisition of the companies SOON Energy Polska sp z.o.o. and Zielona-Energia (see note 6). Goodwill impairment test analysis – EDP Group The recoverable amount of the goodwill in subsidiaries is assessed annually, as at 30 September, independently of the existence of any indicators of impairment. The recoverable amount is determined based on the value in use of the assets, calculated using valuation methodologies supported by discounted cash flow techniques, considering market conditions, the time value of money and the business risks. Any impairment losses are recognised in the income statement for the period. EDP Group segments based on which the Group monitors its activity are as follows (see note 51): • Renewables - corresponds to the activity of producing electricity through renewable energy sources, with emphasis on hydro, wind and solar; • Networks - corresponds to the electricity distribution and transmission activity, including regulated energy retailers; • Client Solutions and Energy Management - includes the following activities: production of electricity using non-renewable energy sources, with emphasis on coal and gas; commercialization of electricity and gas and energy solutions services to customers; and the intermediation business responsible for managing the purchase and sale of energy in the Iberian and Brazilian markets, as well as for the respective hedging operations; For the purposes of these tests, the EDP Group has defined a set of assumptions to determine the recoverable amount of the main investments by each cash generating unit, being presented by aggregation in each business units after the impairment tests carried out at each subgroup/cash generating unit. Goodwill impairment test analysis – Renewables Segment The future cash flows are based on the useful life of wind farms, solar and hydro assets. This projection also considers long-term energy sales contracts and long-term energy price estimates, for assets with market exposure. The main assumptions on which impairment tests are based are as follows: \- Regarding the production of wind and solar energy, the “net capacity factors” used for each cash-generating unit consider: (i) the installed capacity and the forecast resulting from the studies on the occurrence of wind in the long term; and (ii) that regulatory mechanisms in almost all geographies determine the production and priority of energy dispatch whenever weather conditions permit; \- Regarding hydro production, the “net capacity factors” used for each cash-generating unit consider: (i) the installed capacity and the forecast for hydraulic production; and (ii) that the regulatory mechanisms in each geography; 

Integrated Annual Report 2022 Financial Statements and Notes 287 \- Energy remuneration: the approved or contracted remunerations were considered in the event of long-term energy sales contracts for the total or partial useful life of the assets or remunerations determined by the regulatory framework in force in each geography. In the remaining cases, the long-term market price curves projected by the Group were used based on past experience and internal models built on the basis of external information sources; \- Operating costs: the land and maintenance contracts in force were used. The other operating costs were projected consistently based on the experience acquired, on the Budget approved for the next year and taking into account internal analysis models; \- Terminal value: considered as a 15% of the initial investment in each wind farm, considering inflation; and \- Discount rate: the discount rates used are post-tax, reflect EDP Group’s best estimate of the risks specific to each CGU and range as follows: 2022 2021 Europe (EUR) 3.7% - 4.8% 2.9% - 4.0% North America (USD) 5.7% - 7.1% 4.8% - 6.7% Brazil (BRL) 7.9% - 9.6% 7.6% - 9.3% Impairment tests were performed taking into account the regulatory changes in each country known at the end 2022. The impairment tests carried out on Goodwill did not lead to any impairment registration. Goodwill impairment test analysis – Grids Segment The cash flow projection assumes the extent of the concessions related to the electricity distribution business in Brazil. In the case of the concession in Spain, it is perpetual. These cash flows are estimated considering the volume of production and expected consumption, installed capacity, the evolution forecast of the tariff and the energy purchase / sale agreements. The discount rates after taxes used in the networks segment for the purposes of impairment tests ranged between 3.8% (Spain) and 8.5% (Brazil in BRL) (2021: between 3.2% and 7.4% respectively). The main assumptions used to project cash flows are as follows: \- Investment costs: the best available estimates of the investments to be made were used to ensure regular use of current assets, as well as those resulting from legislative changes; \- Regarding operating costs, the projections made considered the current operating costs projected based on the historical experience acquired, in the Budget approved for the next year and taking into account internal models of analysis; \- The most recent remuneration rates proposed by ANEEL and CNMC ("Comisión Nacional de los Mercados y la Competencia") were considered, applying the updating mechanisms as provided for in the regulation; \- The projections for the electricity distribution businesses are based on long-term estimates of the various assumptions considered in the analysis; \- The terminal value of the distribution assets corresponds to the present value of the net assets at the end of the concession ("Net Regulatory Asset Base”). Sensitivity analyzes were carried out on the results of the impairment tests carried out, namely at discount rates. The results of the sensitivity analyzes carried out conclude that an increase of 50 basis points in the different discount rates, does not determine the existence of signs of impairment in "goodwill" or concession rights. 20\.

In the context of impairment tests carried out at EDP Group, the financial investments held by EDP, S.A. in subsidiaries are reviewed, based on the higher of the value in use and the fair value less costs related to the sale. The main assumptions considered in the valuation models of the main financial holdings in Portugal of EDP, S.A. are as follows: \- The discount rates used reflect the best estimate regarding the specific risks associated to each subsidiary activity within a range between 3.7% and 5.8% (2021: between 3.2% and 5.1%); \- For the activities subject to regulation, the remunerations currently in force and/or approved were considered, applying the updating mechanisms as provided for in the regulation, and incorporates the expectation of renewal of the concessions currently in force and the best estimate of CAPEX and the future regulatory framework; \- Fuel prices (brent, gas, coal and CO2 licenses) and electricity prices forecast were defined considering market expectations for future prices and the application of internal models for building price curves, taking into account the regulatory framework in force and the best expectation regarding its future evolution. Regarding fuel prices, the prices and clauses established in long-term supply contracts, including gas purchase contracts, were also considered. Production assets were valued from a portfolio management perspective, without prejudice to an individual analysis as to recoverability, based on the estimate of the evolution of the market share; \- The production estimates were based on an average hydrological year over the projection period for the hydroelectric plants, the estimated evolution of demand, market share projections and current installed and under construction capacity, as well as the best estimate of the plants to be decommission in the projection period; \- Additionally, other system costs are considered, such as: ISP and CO2 addition fee, CESE and other income; \- The operating costs considered were based on extrapolations from current operating costs based on the knowledge acquired in each activity. The impairment tests led to the recording of an impairment on EDP GEM Portugal, S.A., for the amount of 12,100 thousand Euros in the equity participation and 14,530 thousand Euros in shareholders loans (see note 13). There were no additional impairments, beside the one already The assumptions used in the valuation models of EDP S.A.'s financial holdings in other geographies, as well as the respective sensitivity analyses are described in note 19. 21\.

The company uses several inputs on making its assessment of the credit risk related to these assets, such as the analysis of the historical possible delays and/or impairment losses indications, companies rating (when applicable) and market and macroeconomic data that may change the probability of default and the expectation of delays in the receivable amounts. According to the analysis performed, as per 31 December 2022, impairment was recognized on granted loans to EDP GEM Portugal, S.A. (see note 20). The variation of the caption Loans to related parties - Current, on a consolidated basis, is mainly due to new loans granted to OW FS Offshore, S.A. in the amount of 319,246 thousand Euros, being the total amount of loans granted 326,814 thousand Euros at 31 December 2022. The variation in the item Guarantees rendered to third parties is essentially explained by the significant increase in electricity and gas prices, which originated the need to reinforce collateral/collateral usually requested for transactions in these markets.

Integrated Annual Report 2022 Financial Statements and Notes 316 Following the decision and implementation of the autonomisation of the Medical Plan and Death Subsidy Plan in Portugal, EDP Group has made contributions of 34,560 thousand Euros in 2022 (31 December 2021: 11,520 thousand Euros). In the following years, until the end of 2027 and in the scenario where the liabilities associated with the mentioned plans are not 100% financed, the Group estimates to make additional contributions in the approximate total amount of 104 million Euros, in line with the financing plan approved by Insurance and Pension Funds Supervisory Authority (ASF) (see note 44). The Pension Plans in Portugal, Spain and Brazil are subject to several risks, in which are included the risk of changes in market rates (which impacts the discount rate and the fixed rate of return rate on assets), the risk of changes on the expected lifetime of plan participants, the risk of changes on the pension increase rate and the risk of changes on the social security pension increase, to which are made the following sensitivity analysis for the liabilities at the end of the period: Thousand Euros Portugal Spain Brazil Increase Decrease Increase Decrease Increase Decrease Discount rate (0.5% movement) -29,617 31,790 -108 103 -10,168 11,032 Mortality (increase of 1 year in expected lifetime of plan participants) 32,265 \- 3,820 The solvency level of the fund for the financing of pension plan liabilities in Portugal may vary not only from the risks described above, but also from the performance of the different classes of assets that comprise it.

The medical care and other benefits Plans in Portugal, Spain and Brazil are subject to several risks, in which are included the risk of changes in market rates (which impacts the discount rate and the fixed rate of return rate on assets), the risk of changes in the health care costs and the risk of changes on the expected lifetime of plan participants, to which are made the following sensitivity analysis for the liabilities at the end of the period: Health care cost trend (0.5% movement) -14,989 -11,080 \- \- \- \- Mortality (increase of 1 year in expected lifetime of plan participants) 11,678 \- 7,716 The level of solvency of the fund for the financing of post-employment medical care liabilities in Portugal may vary not only from the risks described above, but also from the performance of the different classes of assets that comprise it.

Provision for legal and labour matters and other contingencies includes provisions for litigation in progress and other labour contingencies, which are related essentially with: i) Requests for the refund of tariff increases paid by industrial consumers of the brazilian subsidiaries EDP São Paulo and EDP Espírito Santo in the amount of 17,181 thousand Euros (31 December 2021: 12,324 thousand Euros). These requests result from the application of Administrative Orders DNAEE no. 38 of 27 February 1986 and no. 45 of 4 March 1986 - Plano Cruzado, effective from March to November 1986; ii) The remaining legal litigations correspond mainly to indemnities for damages allegedly suffered in consequence of interruption of electricity supply, power accidents and fires. Provisions for customer guarantees under current operations include essentially provisions for commercial losses. 

Integrated Annual Report 2022 Financial Statements and Notes 321 Provisions for dismantling and decommissioning includes : (i) 42,525 thousand Euros of the dismantling Trillo nuclear power plant; (ii) 264,762 thousand Euros of the dismantling of wind and solar farms (replacement of sites and land in its original state), mainly, in Europe (110,441 thousand Euros), North America (140,723 thousand Euros), Asia-Pacific (10,913 thousand Euros) and Brazil (2,679 thousand Euros); and (iii) 197,876 thousand Euros of the dismantling and environmental requalification of thermal electro-producing centers in Spain (132,445 thousand Euros) and Portugal (65,431 thousand Euros). These provisions were calculated based on the present value of future liabilities and recorded against an increase in the respective tangible fixed assets, which are amortized over the average useful life of these assets. The calculation of these provisions was based on the following discount and inflation rates: Europe North America Brazil Asia-Pacific Discount Rate [2.24% - 8.75%] [4.02% - 4.42%] [12.40% - 12.50%] [3.50% - 7.67%] Inflation Rate [1.90% - 3.88%] [2.07% - 3.51%] [3.45% - 3.59%] [1.40% - 3.90%] Provision for other liabilities and charges The BOE 223/2017 published during the third quarter of 2017 opened the hearing process of the Order of the Minister of Energy, Tourism and Digital Agenda of 13 September, introducing "lesividad" declaration procedure for the public interest Order IET/980/2016, of 10 June, which established the remuneration of electricity distribution companies until 2016. Thus, the remuneration that has been determined has allegedly been higher than that due for the year 2016. Until the "lesividad" procedure is finitely resolved, the remuneration of the distribution activity for the years 2016, 2017, 2018 and 2019 is considered provisional. With reference to 31 December 2020, EDP España recorded an accumulated provision of 93,105 thousand Euros corresponding to the potential effect of "lesividad" for the financial years 2016, 2017, 2018, 2019 and 2020. Since 2016, EDP España, like other companies in the sector, have been in place with legal proceedings to resolve the “lesividad” procedure. At the same time, companies initiated processes to determine the real value of assets subject to remuneration and proceeded with the reformulation and deposit of their annual accounts from 2014 to 2020, ending this process during 2021. Although no new liquidation or a new regulation has been issued, the companies consider that, in accordance with the order 481/2020 of the Supreme Court, the reformulated and deposited annual accounts must be considered for the calculation of the remuneration. Thus, in 2021, EDP España updated the provision for the “lesividad” procedure for the years 2016 to 2020, reversing it by approximately 47 million Euros. On 1 June 2022, order TED/490/2022, of 31 May, was published in BOE 130/2022, which executes the judgment of the Federal Supreme Court in relation to the declaration of "lesividad" to the public interest of the Order IET/980/2016, of 10 June. The remuneration approved by the Ministry of Ecological Transition and the Demographic Challenge in the referred Order did not take into account the accounts reformulated by the distribution companies, resulting in a notable decrease in their remuneration compared to the expected and accounted values corresponding to a correct execution of the sentence. Subsequently, the "Comisión Nacional de los Mercados y la Competencia" (CNMC) settled the payment obligations arising from the "lesividad" referring to the years 2016, 2017, 2018, 2019, 2020 and 2022 in the Provisional Agreement 5/2022 (partially corresponding to the year 2022) approved by the CNMC on 14 July 2022 and those corresponding to the 2021 financial year in the “2021 Definitive Settlement of regulated activities in the electricity sector”, approved by the CNMC on 4 November 2022. The distribution companies of the EDP Group filed lawsuits against order TED/490/2022 and against the Final Settlement of 2021, in order to obtain the collection of amounts due from a correct execution of the judgment. Before the publication of order TED/490/2022, the provisions corresponding to the expected impact of the execution of the sentence amounted to approximately 47 million Euros. After its publication, the existing provisions were used for this purpose, with the Group recording a receivable in assets, awaiting the decision of the respective lawsuits filed against order TED/490/2022, corresponding to approximately 63 million Euros for the period from 2016 to 2021, and an amount of around 9 million Euros for the period of 2022. On 3 May 2018, it has come to EDP’s knowledge (through a DGEG’s letter) that the CMEC final adjustment had been officially approved, according to ERSE’s proposal, in the amount of 154 million Euros. EDP reflected this reality in its financial statements as of 31 December 2018, recognising a provision by the difference in the final adjustment amounts already recognised in the Group's revenues. On 31 December 2022 EDP maintains the provision in its accounts (see note 4). On 26 September 2018, DGEG notified EDP about a dispatch issued by the Secretary of State for Energy (SSE) on 29 August 2018, which quantifies at 285 million Euros the alleged overcompensation of EDP related to the calculation of the real availability factor of the plants under the CMEC regime. EDP reflected this in the financial statements as at 31 December 2018, through a provision of the same amount. During 2022, EDP made payments of 12,205 thousand Euros, the amount that was still registered, settling the provision as at 31 December 2022 (see note 4). 

Integrated Annual Report 2022 Financial Statements and Notes 322 In their ordinary course of business, EDP Group subsidiaries are involved in several litigations and contingencies (of possible risk) of administrative, civil, tax, labour and other natures. These legal, arbitration or other actions, involve customers, suppliers, employees and administrative authorities. In EDP Group and its legal advisors' opinion, the risk of a loss in these actions is not probable, and the outcome will not affect on a material way its consolidated financial position. The processes whose losses were considered as possible, do not require the recognition of provisions and are periodically reassessed. The detail of possible contingencies is analised as follows: Thousand Euros Group Company Dec 2022 Dec 2021 Dec 2022 Dec 2021 Administrative and Civil 325,437 255,406 336 330 Fiscal 773,643 656,768 13,321 9,541 Other 125,107 114,305 2,791 2,811 1,224,187 1,026,479 16,448 12,682 The events and possible contingencies more relevant in Portugal, are as follows: i) On 29 July 2016, the Portuguese Competition Authority (AdC) has notified EDP S.A. and EDP Comercial, S.A. with a notice for alleged violation of competition laws, regarding the process of the commercial campaign done in partnership with Modelo Continente, designated as "Plano EDP Continente". This was an occasional campaign, limited to two years, which was one of several campaigns usually performed by several other market agents. On 5 May 2017, EDP S.A. and EDP Comercial, S.A. received AdC final decision which applied a fee of 2,900 thousand Euros to EDP S.A. and 25,800 thousand Euros to EDP Comercial. EDP Group is convinced that this campaign has brought real benefits to consumers and competition in markets and that no transgression has been committed. The companies filed their appeal on 19 June 2017 to TCRS. By this court was determined a court hearing that EDP and EDP Comercial would provide security in the amount of 50% of the fine imposed on them by the AdC, and on 19 June 2020, EDP and EDP Comercial provided surety bond and surety in the amounts of 1,450 thousand Euros and 12,900 thousand Euros, respectively. On 30 September 2020, a judgment was issued by the TCRS, which maintained the conviction of the two companies of the EDP Group, as well as Sonae Group's Companies, having also reduced fines by 10%. Fines were determined at 2,610 thousand Euros and 23,220 thousand Euros for EDP and EDP Comercial, respectively. On 30 October 2020, EDP and EDP Comercial appealed the condemnatory sentence handed down by the TCRS, to the Lisbon Court of Appeal. On 6 April 2021, the parties were notified of the judgment handed down by the Court of Appeal of Lisbon, through which it decreed the suspension of the proceedings and the preliminary referral of the case to the Court of Justice of the European Union, under the foreseen mechanism Article 267(b) of the Treaty on the Functioning of the European Union. The case was filed at the Registry of the Court of Justice on 26 May 2021, with written observations having been submitted by the parties on the questions referred by the Lisbon Court of Appeal. The oral trial hearing at the Court of Justice of the European Union took place on 9 November 2022, pending the presentation of conclusions by the Advocate General, which will be followed by the delivery of judgment; ii) On 3 September 2018, the Portuguese Competition Authority (AdC) notified EDP Produção with a Statement of Objections, under which EDP Produção is accused of abuse of a dominant position in the secondary regulation band market (a part of the ancillary services market). AdC claims that EDP Produção has deliberately limited the participation of CMEC plants in the secondary regulation market between 2009 and 2014, benefitting its non-CMEC power plants. The alleged benefit, to the detriment of consumers, would be twofold: receiving higher compensation under CMEC annual adjustment regime; profiting from higher market prices in said market. AdC has estimated that the alleged practice of EDP Produção has generated damages to the national electricity system and to consumers of around 140 million Euros. AdC pointed out that the adoption of a Statement of Objections did not determine the result of the investigation, which began in September 2016 and is still in course. On 28 November 2018, EDP Produção presented to AdC its facts about the accusation. On 18 September 2019, AdC has notified EDP Produção of an alleged infraction to competition rules. This contingency was estimated with a value of 48 million Euros and its graduation was assessed as possible. On 30 October 2019, EDP Produção presented an appeal against this decision to the TCRS. On 20 May 2020, EDP Produção was notified of a decision by the TCRS, which, among other things, admitted its Judicial Challenge Appeal, establishing a purely return effect and determining the payment of the fine imposed within 20 days. In this regard, EDP Produção submitted requests, invoking supervening facts for the demonstration of considerable damage, and arguing defects in the decision that determined the attribution of a mere devolution effect to the Judicial Challenge Appeal. On 16 July 2020, EDP was notified of an order which implied the existence of substantial losses if the fine was paid in advance. Thus, the payment order was therefore suspended. 

Integrated Annual Report 2022 Financial Statements and Notes 323 However, on 12 October 2020, EDP Produção was notified of the appeal filed by the Public Prosecutor's Office, at the Lisbon Court of Appeal, against the TCRS order of 16 July 2020, and considered the existence of considerable damage in the early payment of the fine and suspended the payment order. On 18 November 2020, EDP Produção was notified of a decision by the Lisbon Court of Appeal, granting the appeal presented by the Public Prosecutor and, consequently, revoking the order of TCRS of 16 July 2020. EDP Produção appealed this judgment to the Constitutional Court on 30 November 2020. On 22 February 2021, EDP Produção was notified of the decision of the Constitutional Court in the sense of not knowing the object of the appeal. The case was returned to the TCRS to establish the effect of the appeal filed, to determine whether EDP Produção must pay a fine or provide a guarantee. By order of the same day, the TCRS has scheduled the trial hearing for 27 September, 7, 11 and 25 October, 4, 8, 18, 22 November and 2 and 6 December 2021. On 16 September 2021, the TCRS issued an order that demanded the payment of the fine. Despite having lodged an appeal against this order, on 20 October 2021 EDP Produção paid the amount under appeal, and is waiting for a decision on the appeals submitted. The trial hearing, which began in October 2021, continued with several inquiries until the end of March 2022, with closing arguments taking place on 6 July 2022. On 10 August 2022, the TCRS delivered a judgement, through which it confirmed the conviction of EDP Produção and the imposition of a fine of 48 million Euros, which had already been paid. On 30 September 2022, EDP Produção filed an appeal against the aforementioned decision to the Lisbon Court of Appeal. This was followed by the filing of counter-claims by the AdC and the Public Prosecutor's Office, pending further developments. iii) On 19 July 2021, Celulose Beira Industrial, SA (CELBI), submitted to SU Eletricidade, SA a constitutional request of an Arbitral Tribunal, regarding a conviction of a payment of the energy produced by it under special production in cogeneration, and its interest, since April 2020 (date on which, in accordance with the law and the understanding of DGEG and followed by SU Eletricidade, CELBI has moved to the transitional remuneration scheme provided for in DL No. 23/2010 and Ordinance No. 140/2012), and throughout the term of operation of its Cogeneration Center (which it estimates to be at least 25 years), i.e. at least until 24 March 2035 (supporting this understanding in the fact that the 2002 Remuneration Scheme does not establish any period); or, in the alternative, until 24 March 2030 (claiming that you are entitled to be remunerated under the 2002 Remuneration Scheme for a further 120 months (10 years) from March 2020); or, in the alternative, until November 2020 (claiming that the transition to the 2012 Remuneration Scheme should only take place six months after the effective knowledge of the communication sent by the SRB); or, in the alternative, until August 2020 (in the alternative claiming that the transition from CELBI's remuneration scheme would operate from the beginning of the month following the date of the audit report certifying primary energy savings, which means the transition would operate from August 2020 because the audit report is from July 2020). The overall value of the application amounts to 6,839 thousand Euros and has been classified as possible risk. In October 2021, SU Eletricidade filed a challenge. In February 2022, Procedural Decision no. 1 was delivered, under which the Arbitration Court considered itself competent to adjudicate the dispute between the parties, which was challenged by SU Eletricidade through annulment action filed in March 2022, which is pending at the Central Administrative Court, the pleadings phase has elapsed. In April 2022, the preparatory hearing was held, which was intended in particular to discuss previous questions raised as well as to the fixing of the list of the facts not at issue and the themes of the evidence. In June 2022, the parties filed a joint application alleging supervening facts. The trial hearing took place on 13, 14 and 15 September 2022 and, on 5 of December 2022, the parties presented their final written allegations. On 30 January 2023, the parties were notified of the arbitration judgment, which partially upheld one of the requests made by CELBI (corresponding to 11.75% of them), and SU Eletricidade is currently assessing and considering the respective terms and the possible effects. The possible contingencies more relevant in Brazil, are as follows: i) Investco is involved in a legal action of a civil nature mostly related with indemnity claims resulting from the filling of the hydroelectric reservoir, in the amount of 23,365 thousand Euros (31 December 2021: 17,297 thousand Euros); ii) There is a public civil action filed against EDP São Paulo and EDP Espírito Santo by ADIC – Associação de Defesa dos Interesses Colectivos, claiming a compensation arising from a tariff readjustment on part A from 43 concessionaires. The estimated value attributable to EDP São Paulo and EDP Espirito Santo amounts to 74,402 thousand Euros (31 December 2021: 55,031 thousand Euros); iii) EDP São Paulo is a party to a lawsuit related to the COFINS (Contribution for social security financing) from 1993 to 1995 in joinder with AES Eletropaulo, where is discussed the application of the tax amnesty introduced by the Provisional Measures paragraphs 1858-6 and 1858-8, granted to taxpayers who did not collect COFINS, considering it improper. In the trial of 2nd Instance, was partially confirmed the right to amnesty, and applied the Decree-Law 1,025/69, which established the payment of procedural costs in favour of the National Treasury. From this decision, an appeal was presented, which holds trial. The updated amount as at 31 December 2022 is 14,058 thousand Euros (31 December 2021: 12,267 thousand Euros); iv) EDP São Paulo and EDP Espírito Santo have administrative and judicial actions regarding tax compensations not ratified by the Brazilian Federal Revenue Bureau, which: (i) are protected by judicially recognised credits (IRPJ - Corporate tax income and CSLL - Social Contribution on net profits) and (ii) that result from tax contributions in 2001 of IRPJ, CSLL, PIS (Social integration programme) and COFINS considered to be excessive as a consequence of the application of "Parecer COSIT 26/2002" (Extraordinary Tariff Adjustment - RTE) published by the Brazilian Tax Authorities. According to this opinion, the amounts resulting from tariffs updated under RTE should be recognised and taxed only as of 2002. During 2021 there was a reduction in the amount due to the success obtained in one of the administrative proceedings, cancelling the debt collection. As at 31 December 2022, the updated values amount to 19,736 thousand Euros (31 December 2021: 17,007 thousand Euros); 

Integrated Annual Report 2022 Financial Statements and Notes 324 v) Lajeado has a judicial tax action initiated by the Brazilian Tax Authorities in 2014 aimed at collecting tax contributions (IRPJ and CSLL) resulting from the disallowance of expenses regarding goodwill arising from a business combination (acquisition). As at 31 December 2022, this contingency amounts to 27,388 thousand Euros (31 December 2021: 23,030 thousand Euros); vi) Porto do Pecém was the subject of tax execution procedure in the amount of 17,673 thousand Euros, resulting from alleged non-taxation under IRPJ and CSLL of financial income and exchange variations related to previous periods (31 December 2021: 14,850 thousand Euros); and vii) Following a period of drought in the State of Ceará, the local government, through Decree 32,044 of 16 September 2016, introduced an extraordinary rate called the Emergency Water Charge (EHE) over the actual water consumption of thermoelectric power plants, and in particular the Porto do Pecém. On 13 October 2016, the Porto do Pecém submitted an administrative request to ANEEL for the purpose of transferring this additional cost to the Unit Variable Cost (CVU), in order to restore the economic-financial balance of the contract (CCEAR). ANEEL, through Order 3,293 of 16 December 2016, denied the request of the Porto do Pecém, which initiated proceedings against ANEEL. As at 31 December 2022, the lawsuit is estimated in an amount of 31,214 thousand Euros (31 December 2021: 23,087 thousand euros). During 2020 there was a revision of assumptions used to calculate the contingency which previously was considering the estimative of the value of EHE to be paid following the historical average. The new calculation is based on the claim effective risk considering the transference of CVU. Finally, even if EDP Group classifies its risk as remote, it is important to identify the following litigation: i) On 27 October 2009 and 5 January 2010, the EDP Group received two tax settlements regarding 2005 and 2006 taxable income for the EDP tax Group, which included an adjustment of 591 million Euros regarding its subsidiary, EDP Internacional SGPS, related to the tax treatment considered by the EDP Group in relation to a capital loss generated with the liquidation of a subsidiary, whose main assets consisted of investments in operating subsidiaries in Brazil, namely EDP Espírito Santo and Enersul. As at 31 December 2022, the amount of this tax contingency amounts to 315 million Euros (31 December 2021: 307 million Euros). Considering the analysis made, the technical advice received and a favourable binding opinion obtained from the tax authorities in relation to the nature of the transaction occurred in the year of the assessment, the EDP Group considers as remote the risk associated with this matter. Under this analysis, the capital loss is tax deductible for income tax purposes as established in article 75 no. 2 of the Corporate Income Tax Code ("Código do IRC") based on the wording of the law in force at that date (existing article 81). Given the above, and considering that the EDP Group’s tax procedures comply with applicable Portuguese tax legislation at the date of the events, the Group is currently using all available legal means to contest these additional settlements. Thus, following the implied rejection of the hierarchical appeal, EDP presented a judicial claim, on 6 June 2012. In November 2018, EDP Group was notified with a decision in favour. The Treasury filed an appeal on that decision. 37\.

The fair value of derivative financial instruments is booked in Other debtors and other assets (see note 27) and Other liabilities and other payables (see note 39), according to its nature. Fair value of derivative financial instruments is based on listed market prices, whenever available, or on valuations determined through valuation models that use variables observable on the market. Therefore, according to IFRS 13 requirements, the fair value of the derivative financial instruments is classified as of level 2 (see note 45) and no changes of level were made during this period. These valuation models are based on generally accepted discounted cash flow techniques and option valuation models, using market data obtained through financial information platforms. Derivative financial instruments classified as trading are financial hedging instruments contracted for economic hedging at EDP Group level (see note 5), however such instruments are not eligible for hedge accounting under IFRS.

Some of the transactions related to the disposal of non-controlling interests while retaining control, carried out in previous years, incorporate contingent assets and liabilities according to the terms of the corresponding agreements. Additionally, some of the assets acquisition transactions foresee contingent liabilities which depend on certain milestones and, although EDP Group has recognized the fair value of these liabilities in the consolidated financial statements, changes in the assumptions could change these liabilities.

As a result, in December 2022, EDP and EDP Produção, Hidroelétrica do Guadiana and Greenvouga entered into the mandate contract for the placement (purchase and sale) of electricity on the market (“Contract”) produced by hydroelectric and natural gas combined cycle plants in Portugal during the years 2023 and 2024. Within the scope of this Contract, as of 1 February 2023, EDP will issue dispatch instructions to EDP Produção, Hidroelétrica do Guadiana and Greenvouga, in order to adapt the production of electricity to the offers it makes on the market. In addition, EDP started to assume, in full and upon payment of a substantially fixed consideration, the economic risks and benefits associated with the dispatch of electricity production and subsequent placing on the market and the purchase of fuels and CO2 licenses necessary for the operation of the Thermal Power Plants, with the volatility associated with price and volume variation related to electricity and fuels being substantially assumed by EDP S.A. Within the scope of this Contract, EDP will be responsible for: \- issue Dispatch Instructions relating to the electricity to be produced by the Electric Power Plants for placing on the market; \- carrying out an adequate programming of the operation of the Electric Power Plants, taking into account the fulfillment of the contractual or legal obligations to which EDP Produção, Hidroelétrica do Guadiana and Greenvouga are bound in their capacity as holder of the production and exploration licenses; \- develop all necessary actions for the acquisition and supply of fuels, as well as the CO2 licenses necessary for the operation of the Thermal Power Plants; and \- ensure the relationship with the Market Operator and the System Operator, as well as with any other official entities and with counterparties. In turn, EDP Produção, Hidroelétrica do Guadiana and Greenvouga will be responsible for: \- ensure the production of electricity in accordance with EDP's dispatch instructions, managing the Electric Power Plants, in order to maximize efficiency, availability and safety, as well as ensuring compliance with all legal, regulatory and contractual requirements in the production of electricity; \- fully ensure the operation and maintenance of the Electric Power Plants, bearing all costs associated with this operation and maintenance; \- comply with the Dispatch Instructions given by EDP in order to minimize Deviations and ensure the provision of the Complementary Services requested, as well as the applicable System Services, without prejudice to, in a justified and reasoned manner, refuse the execution of a Dispatch Instruction for the production of electricity on a given day and time, in cases where this is necessary to ensure compliance with contractual or legal obligations to which they are attached in their capacity as holders of production and exploration licenses; and \- manage the relationship with all public or private entities that intervene in matters that impact the operation of the reservoirs, in activities that interfere with the normal operation of the Electric Power Plants, as well as manage the relationship with REN Gasodutos, as operator of the national network of gas transport, within the scope of the operational management of natural gas. The increase in future cash flows, on an individual basis, includes mainly this contract, which was included in the Transfer ("Trespasse") (see note 46).

Fair value of EDP Group’s financial debt was determined considering current market, namely listed price (level 1). The market value of financial debt, when no listed market prices are available, is calculated based on the discounted cash flows at market interest rates at the balance sheet date, increased by the best estimate, at the same date, of market conditions applicable to Group's debt. According to IFRS 13 requirements, EDP Group established the way it obtains the fair value of its financial assets and liabilities. The levels used are defined as follows: ● Level 1 – Fair value based on the available listed price (not adjusted) in the identified active markets for assets and liabilities; ● Level 2 – Fair value based in market inputs not included in level 1, but observable in the market for the asset or liability, either directly or indirectly; ● Level 3 – Fair value of the assets and liabilities calculated with inputs that are not based on observable market information.

Integrated Annual Report 2022 Financial Statements and Notes 349 The amounts receivable from concessions - IFRIC 12 at fair value through profit or loss are valued based in the methodology of the Value of Replacement as New (VNR). This method requires that each asset is valued, at current prices, for all the expenses needed for its replacement by equivalent asset that performs the same services and has the same capacity as the existing asset. The valuation for each asset is based on (i) Data Bank of Referential Prices - which is defined in the Tariff Adjustment Procedures - PRORET; or (ii) Data Bank of Prices from the Distribution company - which is formed based on the company's own information; or (iii) Referential Budget – that corresponds to the calculation by comparison of market data, relating to other assets with similar characteristics. ANEEL reviews the VNR, through the valuation report of the Regulatory Remuneration Base, every three years for EDP Espírito Santo and every four years for EDP São Paulo, as established in the concession contracts. The market value of investment properties is based on assessments using current market practices: the comparative method, in cases where there is an active and comparable market, the income method, through discounted cash flows and the cost method, which considers the market value of the land and the construction costs. The movement in financial assets and liabilities included in Level 3 is as follows: At fair value through other comprehen- profit or loss Thousand Euros sive income Balance at beginning of period 31,016 63,115 Change in fair value (see note 22) 248 7,082 Acquisitions 25,591 6,903 Disposals -3,747 \- Other changes 3,100 48 Balance at the end of the period 56,208 77,148 The assumptions used in the determination of Equity Instruments at Fair Value are described in note 22, as required by IFRS 13. 46\.

Business combinations Sunseap Group EDP Renováveis, S.A (EDPR) entered in November 2021 into an agreement with BPIN Investment Company Limited (owner of 47% of shares) , Mr. Frank Phuan and Mr. Lawrence Wu (as the “Founder Shareholders” and owners of 14% of shares), and the additional selling shareholders (owners of 36% of shares) for the acquisition of up to 91.4% of the shares of Sunseap Group Pte.Ltd which holds a portfolio including of close to 10 GW of renewable projects at different stages of development. The agreement also includes the acquisition of the subscription rights granted to some shareholders and employees of the company by EDPR and the new issuance of those shares to be paid by EDPR. The completion of this transaction was subject to customary conditions precedent that were completed in February 2022. EDPR acquired 91.4% of the mentioned Group for a total consideration of 659,658 thousand Euros. This transaction is considered under the scope of IFRS 3 - Business combinations. Upon completion of the agreement, Sunseap Group Pte.Ltd performed a capital increase which was subscribed solely by EDP Renováveis, S.A and lead to EDP Renováveis, S.A holding 92.28% of the total stake of the acquired company. The amount of the capital increase was not considered within the consideration transferred for the business combination. Additionally, EDPR holds call options to acquire the remaining stake of the capital of the Sunseap Group and the sellers have put options to sell their shares. Considering the principles of IFRS 3 Business Combinations and in order to follow consistently the Group's policy in similar situations, EDPR recognized in the Consolidated Financial Statements the put option as a liability, measured at fair value at the date of acquisition (IAS 32), and following the premises stated for the anticipated-acquisition method, would recognize 100% of investment in the Consolidated Financial Statements. This transaction will not give rise to any Non-Controlling Interests (NCI), since EDPR has acquired the 92.28% of Sunseap Group and has assumed an anticipated acquisition of the remaining 7.72% due to the put option over NCI. The exercise price for these options has been determined in an amount equal to 56,442 thousand Euros (see note 39). The Group used the financial statements as at 28 February 2022 of the company acquired, to determine pre-acquisition balance sheet and results, and, consequently, the companies have been consolidated from that date following the full consolidation method. Thus, this acquisition has contributed to the consolidated financial statements with Revenues, mainly from energy sales, in the approximate amount of 108,763 thousand Euros and with a Net profit in the approximate amount of 224 thousand Euros, referring to the ten-month period ended at 31 December 2022. If this acquisition had occurred in the beginning of the exercise, it would have contributed to the consolidated financial statements with revenues, mainly from energy sales, in the approximate amount of 121,430 thousand Euros and with a Net loss for the period in the approximate amount of 7,623 thousand Euros, referring to the twelve-month period ended at 31 December 2022. 

Integrated Annual Report 2022 Financial Statements and Notes 353 At the acquisition date, EDPR Group has determined the fair value of the assets acquired and liabilities assumed, with the assistance of a specialized and independent firm. The valuation methodology utilized has been the Multi-Excess Earning Method (MEEM) and the discounted cashflow approach. This valuation methodology assumes that the kind of assets to be valued normally generates cash flows in combination with other tangible and intangible assets and therefore consists in deducting the estimated cost of the use of other assets, such as PP&E or working capital, from the estimated cash flows associated to the asset to be valued. The main components of cashflow, namely production, long term power prices and operational costs were estimated using EDPR’s own methodology using historical data and experience assessing investments of similar solar PV projects in EDR’s portfolio. These internal assumptions used in the preparation of the cashflows of the portfolio have been challenged by the specialized firm. The after tax cash flows were then discounted at the weighted average cost of capital within a range of 6.3-10.8% (blended), that has been calculated by the firm, reflecting the risks of the specific countries and adjusted for the profile of each project. Such valuation has determined a fair value of the net assets acquired in the amount of 296,173 thousand Euros. Fair values of identifiable assets and liabilities at the acquisition date are presented as follows: Thousand Euros Book value at acquisition date Fair value adjustment Fair value at acquisition date Assets Property, plant and equipment 409,589 110,932 520,521 Right-of-use assets 39,000 \- 39,000 Intangible assets 422 113,295 113,717 Goodwill 2,159 -2,159 \- Investments in joint ventures and associates 9,111 14,842 23,953 Deferred tax assets 9,908 \- 9,908 Other debtors and other assets 145,038 \- 145,038 Cash and cash equivalents 127,576 \- 127,576 Total Assets 742,803 236,910 979,713 Liabilities Financial Debt 264,172 \- 264,172 Provisions 6,163 \- 6,163 Deferred tax liabilities 1,836 38,836 40,672 Other liabilities and other payables 334,547 \- 334,547 Total liabilities 606,718 38,836 645,554 Net Assets 136,085 198,074 334,159 Non-controlling interests -37,986 Net assets acquired at fair value 296,173 Acquisition cost 659,658 Goodwill 363,485 The aforementioned Sunseap's group valuation has determined a fair value for Property, plant and equipment in the amount of 520,521 thousand Euros, generating a fair value adjustment of 110,932 thousand Euros corresponding to the permits, licenses and concessions and an associated deferred tax liability in the amount of 21.472 thousand Euros (see note 16 and 24). Furthermore, the valuation has determined a fair value for Intangible assets in the amount of 113,717 thousand Euros, generating a fair value adjustment of 113,295 thousand Euros corresponding to the power purchase agreements and feed-in-tariffs of the whole portfolio and an associated deferred tax liability in the amount of 17,378 thousand Euros (see note 18). The purchase price allocation exercise carried out in accordance with IFRS 3 resulted in a goodwill recognition in the amount of 363,485 thousand Euros, as per the difference of the net assets acquired at fair value and the consideration transferred for the acquisition of the shares. The aforementioned goodwill recognition resulting from the purchase price allocation, is mainly attributable to EDPR's establishment in the APAC platform within the context of EDP Business plan 2021-2025, allowing EDPR to establish a portfolio for the APAC region of close to 10 GW of solar projects, of which 563 MW operating and under construction, and an experienced team of more than 600 employees spread across 9 markets, providing a growth platform for the region. 

Integrated Annual Report 2022 Financial Statements and Notes 354 Xuan Thien EDP Renováveis, S.A. (EDPR), through its subsidiary Sunseap Commercial & Industrial Assets (Vietnam) Co., Ltd. entered in 2022 into an agreement with Xuan Thien Group for the acquisition of 99,99% of the shares of Xuan Thien Ninh Thuan JSC and Xuan Thien Thuan Vac JSC, each of one holding a PV project totalling 200 MWac (255MWdc) (see note 6). The completion of this transaction was subject to customary conditions precedent that were completed in 7 September 2022. The total consideration for this transaction was 202,298 thousand Euros (213,030 thousand USD) which includes an amount of 41,288 thousand Euros that corresponds to the retentions that, in accordance with the sale and purchase agreement, will be paid when certain milestones related to financing, module damages repairs and land use rights are fulfilled (see note 39). This transaction is considered under the scope of IFRS 3 - Business combinations. The Group used the financial statements as at 7 September 2022 of the companies acquired, to determine pre-acquisition balance sheet and results, and, consequently, the companies have been consolidated from that date following the full consolidation method. Thus, this acquisition has contributed to the Consolidated Financial Statements with Revenues, mainly from energy sales, in the approximate amount of 9,319 thousand Euros and with a Net profit in the approximate amount of 1,819 thousand Euros, referring to the four months period ended at 31 December 2022. If this acquisition had occurred in the beginning of the exercise, it would have contributed to the consolidated financial statements with revenues, mainly from energy sales, in the approximate amount of 33,225 thousand Euros and with a Net profit for the period in the approximate amount of 8.985 thousand Euros , referring to the twelve-month period ended at 31 December 2022. At the acquisition date, EDPR Group has determined the fair value of the assets acquired and liabilities assumed, with the assistance of a specialized and independent firm. The valuation methodology utilized has been the Multi-Period Excess Earning Method (MEEM) and the discounted cashflow approach. This valuation methodology assumes that the kind of assets to be valued normally generates cash flows in combination with other tangible and intangible assets and therefore consists in deducting the estimated cost of the use of other assets, such as PP&E or working capital, from the estimated cash flows associated to the asset to be valued. The main assumptions of cashflow, namely production, long term power prices and operational costs were estimated using EDPR’s own methodology using historical data and experience assessing investments of similar solar assets in EDPR’s portfolio. These internal assumptions used in the preparation of the cashflows of the portfolio have been challenged by the specialized firm. The after tax cash flows were then discounted at the weighted average cost of capital, that has been calculated by the firm, reflecting the risk of the country and adjusted for the profile of the projects. Such valuation has determined a fair value of the net assets acquired in the amount of 181,062 thousand Euros. Fair value of identifiable assets and liabilities at the acquisition date is presented as follows: Thousand Euros Book value at acquisition date Fair value adjustment Fair value at acquisition date Assets Property, plant and equipment 171,487 26,754 198,241 Intangible assets \- 85,476 85,476 Deferred tax assets \- 237 237 Other debtors and other assets 18,064 -16 18,048 Cash and cash equivalents 314 \- 314 Total Assets 189,865 112,451 302,316 Liabilities Financial Debt 102,777 \- 102,777 Provisions 2,303 \- 2,303 Deferred tax liabilities \- 8,497 8,497 Other liabilities and other payables 4,522 3,155 7,677 Total liabilities 109,602 11,652 121,254 Net Assets 80,263 100,799 181,062 Net assets acquired at fair value 181,062 Acquisition cost 202,298 Goodwill 21,236 The aforementioned Xuan Thien's projects valuation has determined a fair value for Property, plant and equipment in the amount of 198,241 thousand Euros, generating a fair value adjustment of 26,754 thousand Euros corresponding to the permits, licenses and concessions (PLCs) and an associated deferred tax liability in the amount of 2,026 thousand Euros (see note 16 and 24). Furthermore, the valuation has determined a fair value for Intangible assets in the amount of 85,476 thousand Euros, which equals the amount of the fair value adjustment corresponding to the power purchase agreements that these companies have in place and an associated deferred tax liability in the amount of 6,471 thousand Euros. 

Integrated Annual Report 2022 Financial Statements and Notes 355 The purchase price allocation exercise carried out in accordance with IFRS 3 resulted in goodwill recognition in the amount of 21,236 thousand Euros, as per the difference of the net assets acquired at fair value and the consideration transferred for the acquisition of the shares. The aforementioned goodwill recognition resulting from the purchase price allocation, which is identified according to what is indicated in note 2.A, is mainly attributable to EDPR doubling its operational capacity in Vietnam, strengthening its presence in the APAC region, a market where it entered in 2021 and has been since reinforced with the integration of Sunseap in February 2022. Kronos Group In the third quarter, EDP Renewables Europe, S.L.U. entered into an agreement with Summercourt Capital GmbH (owner of 85% of the shares) and Bohne-Vermögensverwaltungs-GmbH (owner of 15% of the shares) to acquire a 66,80% stake of Kronos Solar Projects Gmbh which holds a solar generation portfolio of 9,4GW under development located in Germany, Netherlands, France and UK (see note 6). The completion of this transaction was subject to customary conditions precedent which were completed in 5 October 2022. Subsequently, Kronos Solar Projects GmbH carried out a capital increase which was fully subscribed by EDP Renewables Europe, S.L.U., thus increasing the total stake in the acquired company to 70% and assumed the anticipated acquisition of the remaining 30% due to the put option on the Non Controlling Interest. The value of the capital increase was not considered in the amount transferred for the business combination. Thus, the total acquisition value of this shareholding amounted to 663,030 thousand Euros, of which the amount of 341,995 thousand Euros corresponds to the estimated value for exercising the agreed put options and the amount of 71,035 thousand Euros relating to the estimate of success fees to be paid to the sellers (see note 39). This transaction is considered under the scope of IFRS 3 - Business Combinations. The Group used the financial statements as at 30 September 2022 of the acquired companies, to determine pre-acquisition balance sheet and results, and, consequently, the companies have been consolidated from that date following the full consolidation method and equity method when applicable. Thus, this acquisition has contributed to the consolidated financial statements with no revenues since none of the projects of the portfolio are operating and no sales of projects have occurred during the period and with a Net loss in the approximate amount of 438 thousand Euros, referring to the four-month period ended at 31 December 2022. If this acquisition had occurred in the beginning of the exercise, it would have contributed to the consolidated financial statements with no revenues since none of the projects of the portfolio are operating and no sales of projects have occurred during the year and with a Net loss in the approximate amount of 1,176 thousand Euros, referring to the twelve month period ended at 31 December 2022. Fair value of identifiable assets and liabilities at the acquisition date is presented as follows: Thousand Euros Book value at acquisition date Fair value adjustment Fair value at acquisition date Assets Property, plant and equipment 4,871 \- 4,871 Intangible assets 3,331 \- 3,331 Other debtors and other assets 2,045 \- 2,045 Cash and cash equivalents 13,423 \- 13,423 Total Assets 23,670 \- 23,670 Liabilities Provisions 493 \- 493 Deferred tax liabilities 151 \- 151 Other liabilities and other payables 11,565 \- 11,565 Total liabilities 12,209 \- 12,209 Net Assets 11,461 \- 11,461 Non-controlling interests 88 Net assets acquired at fair value 11,373 Acquisition cost 663,030 Goodwill 651,657 At the acquisition date, EDPR Group has determined internally the fair value of the assets acquired and liabilities assumed. Since the portfolio acquired is still in an early stage of development EDPR has taken a cautious approach and has not allocated any value to specific assets, hence the difference amounting to 651,657 thousand Euros between the consideration transferred and the net assets acquired has been allocated to goodwill. 

Integrated Annual Report 2022 Financial Statements and Notes 356 The aforementioned goodwill recognition resulting from the purchase price allocation, which is identified as provisional according to what is indicated in note 2.A, is mainly attributable to the opportunity of entrance in new regions for EDPR (namely Netherlands and Germany), which benefit from ambitious renewables targets given the increased importance of security of supply and energy independence coupled with government initiatives such as the “Easter Package” in Germany that stands out with ambitious renewables capacity targets, with 360 GW of renewable installed capacity until 2030. In that sense almost 50% of the acquired solar development portfolio is located in Germany. Another element to consider within the goodwill is the well-proven know-how and track record of Kronos’s team with 1,4 GW developed through 80 successfully installed projects in 9 countries. Finally, this acquisition is considered to be highly complementary with EDPR geographical current set up, not only allowing the entrance in Germany and Netherlands, but also scaling presence in France and the UK with a fully solar focused business. Longroad EDPR through its subsidiary, EDPR NA Distributed Generation, LLC, entered into an agreement in April 2022 to acquire 100% of the equity interests in eighty four companies owning an aggregate nameplate capacity of 99.3 MW of operating solar plants located throughout the US. The acquisition of these companies has been structured in 8 different transactions (tranches) which are independent from each other. However, given that the seller is the same, the assets have same nature and risks and are all located in the same geography, the Group has opted to present all these transactions aggregated in the same note, grouping the assets and liabilities acquired depending on whether the transaction has generated goodwill or badwill. The completion of this transaction was subject to certain conditions precedent, which were specific for each acquired company, necessitated multiple closings of discrete asset groups in separate tranches. With the aforementioned conditions precedent fulfilled, EDPR acquired the aforementioned 100% equity interests in 84 companies in four tranches, each of which is considered under the scope of IFRS 3 – Business combinations, for the following cash consideration: Purchase Closing Date Projects Price Capacity acquired thousand (MW dc) Euros 19 April 2022 (1) 7 16,659 6.46 9 August 2022 (2) 3 248 1.82 9 August 2022 (1) 6 3,522 10.65 9 August 2022 (1) 2 2,623 1.22 3 October 2022 (2) 7 38,257 24.19 3 October 2022 (2) 18 22,867 16.93 9 December 2022 (3) 11 3,661 5.94 9 December 2022 (3) 30 45,155 32.09 84 132,992 99.3 (1) acquisitions which generated goodwill (2) acquisitions which generated badwill (3) acquisitions which the purchase price allocation has not yet been finalized The Group used the financial statements as at each respective closing date to determine pre-acquisition results and, consequently, the companies and their operations have been consolidated since that date. The profit and loss and statement of cash flows reflect the activity of these project companies from the respective date of closing presented in the table above. If these acquisitions had occurred at the beginning of 2022, these would have contributed to the consolidated financial statements with Revenues, mainly from energy and environmental attribute (REC) sales, in the approximate amount of 14,244 thousand Euros (15,000 thousand USD) and with Net income for the period in the approximate amount of 2,279 thousand Euros (2,400 thousand USD), referring to the twelve- month period ended at 31 December 2022. At the acquisition dates for each respective tranche, the Group has determined the fair values of the assets acquired and liabilities assumed, based on valuations performed by a third party. The valuation methodology utilized was a discounted cashflow approach, where cash flows for each project were forecasted for the remaining life of the assets. The main components of cashflow, namely production, long term power prices and operational costs were estimated using EDPR’s own methodology using historical data of the assets provided by the seller. The after tax cash flows were then discounted at the weighted average cost of capital of 8.25% reflecting the risk of the debt and equity financing components adjusted for the contracted profile of each project. Lastly to the aggregate value of the portfolio, adjustments were made for one- off items, other balance sheet assets or liabilities and synergies, to reach the final equity valuation. 

Integrated Annual Report 2022 Financial Statements and Notes 357 Such valuation has determined a fair value of the net assets acquired in the amount of 77,372 thousand Euros. Inputs and assumptions included in the valuation models relied upon the use of significant estimates including market energy pricing curves, federal income tax rates and other present value factors. Fair values of identifiable assets and liabilities at the acquisition dates for tranches resulting in goodwill from the transaction are presented as follows: Thousand Euros Book value at acquisition date Fair value adjustment Fair value at acquisition date Assets Property, plant and equipment 41,506 \- 41,506 Intangible assets \- 11,570 11,570 Other debtors and other assets 3,800 \- 3,800 Cash and cash equivalents 129 \- 129 Total Assets 45,435 11,570 57,005 Liabilities Provisions 4,416 -3,702 714 Institutional partnerships in US 2,821 -212 2,609 Other liabilities and other payables 37 \- 37 Total liabilities 7,274 -3,914 3,360 Net Assets 38,161 15,484 53,645 Net assets acquired at fair value 53,645 Acquisition cost 61,372 Goodwill 7,727 The purchase price allocation exercise carried out in accordance with IFRS 3 resulted as a Goodwill recognition in the amount of 7,727 thousand Euros, as per the difference of the net assets acquired at fair value and the consideration transferred for the acquisition of the shares of these projects. This goodwill is mainly attributable to the acquisition of above-market power purchase agreements. Fair values of identifiable assets and liabilities at the acquisition dates for tranches resulting in badwill from the transaction are presented as follows: Thousand Euros Book value at acquisition date Fair value adjustment Fair value at acquisition date Assets Property, plant and equipment 29,273 \- 29,273 Intangible assets \- 9,097 9,097 Other debtors and other assets 3,516 \- 3,516 Cash and cash equivalents 1,662 \- 1,662 Total Assets 34,451 9,097 43,548 Liabilities Provisions 1,639 -1,280 359 Institutional partnerships in US 22,071 -2,900 19,171 Other liabilities and other payables 291 \- 291 Total liabilities 24,001 -4,180 19,821 Net Assets 10,450 13,277 23,727 Net assets acquired at fair value 23,727 Acquisition cost 22,804 Badwill -923 The purchase price allocation carried out in accordance with IFRS 3 resulted in a badwill recognition in the amount of 923 thousand Euros. Additionally, the purchase price allocation has not yet been finalized for the projects acquired on 9 December 2022. The book value of the net assets of these projects at the acquisition date amounted to 27,578 thousand Euros, with goodwill having been recognized in these transactions in amounting to 21,238 thousand Euros (see note 19). EDP Goiás On 14 October 2021, EDP Energias do Brasil S.A, won the public auction for 100% of the equity shares of Celg Transmissão S.A,. Following this auction, on 7 February 2022, EDP - Energias do Brasil acquired 99.99% of Celg Transmissão S.A., later renamed EDP Transmissão Goiás S.A., for an amount of 2,114 million brazilian Reais (375 million Euros). This transaction is considered under the scope of IFRS 3 - Business combinations (see note 6). 

Integrated Annual Report 2022 Financial Statements and Notes 358 EDP Goiás has a portfolio of 755 km of transmission network and operates 14 substations, predominantly through the Brazilian State of Goiás, with three contracted concessions until 2043, 2045 and 2046. This transaction reinforces EDP Brasil's growth cycle, with an emphasis on the distribution and transmission segments. The Group used the financial statements as at 31 January 2022 of the company, to determine pre-acquisition balance sheet and results, and, consequently, has consolidated from that date onward using the full consolidation method. Thus, this acquisition has contributed to the Consolidated Financial Statements with Revenues, mainly Revenue from assets assigned to concessions, in the approximate amount of 70,241 thousand Euros and with a Net profit in the approximate amount of 14,497 thousand Euros, referring to the eleven-month period ended at 31 December 2022. If this acquisition had occurred in the beginning of the exercise, it would have contributed to the consolidated financial statements with Revenues, mainly Revenue from assets assigned to concessions, in the approximate amount of 75,465 thousand Euros and with a Net profit for the period in the approximate amount of 15.985 thousand Euros, referring to the twelve-month period ended at 31 December 2022\. With reference to the acquisition date, the book value of net assets in this portfolio amounted to 1,071 million Brazilian Reais (170 million Euros), and an external evaluation determined the allocation of its fair value, which resulted, essentially, in the recognition of a concession right (see note 18). The evaluation methodology used was the Multi Period Excess Earning (“MEEM”).

Investigation process about CMEC and DPH Following the enactment of an EU legislation package regarding the construction of the Internal Energy Market, aimed at, among others, promoting the liberalization of the electricity sector, the existence of long-term Power Purchase Agreements (“Contratos de Produção de Energia” – CAE), and the Portuguese legal framework involving a “single buyer”, ceased to be compatible with EU law. Accordingly, Decree-Law no. 240/2004, of 27 December, was enacted in the context of the liberalization of the Portuguese energy sector, establishing the early termination of the CAEs entered into in 1996 and, at the same time, approving the methodology to be used in accomplishing said termination, as well as the compensation due to energy producers in that respect. This methodology was subjected to the European Commission’s (EC) prior approval, expressed in the Decision concerning State aid N161/2004, which deemed it effective and strictly necessary. Additionally, the enactment of the aforementioned Decree-Law by the Portuguese Government was object of a legislative authorization, granted by the Portuguese Parliament. In that context, and according to the approved methodology, EDP and REN - Rede Eléctrica Nacional, S.A. (REN) signed the CAE early termination agreements in 2005, their entry into force having taken place on 1 July 2007, after being amended earlier that same year. Both termination agreements were ratified by the member of the Portuguese Government responsible for the energy sector. 

Integrated Annual Report 2022 Financial Statements and Notes 359 Pursuant to the provisions of the 2005 CAE termination agreements, on 8 March 2008 the Portuguese Government, REN and EDP Produção entered into a number of concession agreements formalizing EDP’s right of use over the Public Hydro Domain (“Domínio Público Hídrico” – DPH) until the end of the operational life of the hydroelectric plants subject to the so-called Costs for the Maintenance of the Contractual Balance mechanism (“Custos de Manutenção do Equilíbrio Contratual“ – CMEC). Decree-Law 226-A/2007, of 31 May, introduced a new obligation to EDP, unforeseen in the 2004 legislation or in the 2005 termination agreements, which consisted in the payment by EDP of an amount concerning the “economic and financial balance” of each power plant. Pursuant to this legal framework, and following assessments carried out by two independent financial institutions appointed by the Government, EDP Produção was ordered to pay EUR 759 million, as consideration for the extension of its right of use over the DPH. This included approximately EUR 55 million due for the Hydro Resources Tax. In 2012, the EC and Portuguese authorities (the Central Department of Criminal Investigation and Prosecution, a part of the Public Prosecutor’s Office – “Departamento Central de Investigação e Ação Penal”, DCIAP) received complaints regarding (i) the methodology adopted for the early termination of the CAEs and the implementation of the CMEC mechanism and; (ii) EDP’s right of use over the DPH. So far as the complaint received by the EC is concerned, this institution addressed a clarification request to the Portuguese Government over the early termination of the CAEs, and its replacement by the CMEC framework. The EC decided, in September 2013, that the compensation attributed to EDP Produção in the context of the early termination of the CAEs did not exceed the amount required to reimburse the investment costs meant to be recovered throughout the operational life of the assets in question. Furthermore, it certified that the execution of the CMEC framework respected the terms that were notified to the EC, and approved, in 2004\. Accordingly, the EC has at this stage concluded its investigation regarding the early termination of the CAEs. Having found no evidence of non-compliance with the framework in force in Portugal (approved by the EC itself in 2004) or at the EU level, it decided not to pursue an in- depth investigation on the matter. Simultaneously, in September 2013, the EC decided to undertake an in-depth investigation exclusively in respect of the right of use over the DPH matter. These in-depth investigation proceedings over EDP’s right of use over the DPH were formally concluded in May 2017, with the EC having decided that the consideration paid by EDP was in line with market conditions. It further concluded that the financial methodology followed to determine the price to be paid by EDP for the right of use over the DPH was appropriate and resulted in a fair market price, expressly adding that the accusations that such price (759 million euros) had been underappreciated were baseless, and resulted from an inaccurate financial calculation methodology. In 2 June 2017, EDP was made aware of the investigation being carried out by the DCIAP since 2012 regarding the amounts due to EDP for the early termination of the CAEs and the right of use over the DPH. On that date, the authorities carried out a search in EDP’s offices, as well as REN’s (as network operator) and a consultant. At that time, DCIAP informed, by way of a public press release, that investigations were ongoing, and the alleged facts could amount to active and passive corruption, and economic participation in business deals. The DCIAP further informed, in said press release, that some members of EDP’s Executive Board of Directors, as well as former directors who executed the relevant agreements, were suspects in that investigation. On 6 July 2020, a measure of constraint to suspend the exercise of functions in EDP’s Executive Board of Directors was proposed by the Public Prosecutor’s Office, and applied by the court, to António Mexia and João Manso Neto (then Chairman and member of the board, respectively), while the investigation remained in the inquiry stage. On the same day, the General and Supervisory Board and the Executive Board of Directors resolved to appoint then Chief Financial Officer Miguel Stilwell de Andrade as interim Chairman, for the duration of the impediment of the current Chairman of the Executive Board of Directors, in addition to his functions at the time. On 13 July 2020, and as in due course disclosed to the market (https://www.edp.com/sites/default/files/2020- 07/20200713_Notifica%C3%A7%C3%A3o%20do%20DCIAP_EN_0.pdf ), EDP was notified by the Portuguese Authorities to appoint a legal representative to appear at the DCIAP for questioning and constitution of EDP as defendant, for the facts related to the hiring by EDP Group of the father of the then Secretary of State Artur Trindade. Such diligence has already occurred and EDP was named as a defendant in the context of such judicial procedure and is now waiting for further developments of the procedure. On 30 November 2020, and as communicated to the market on that same date, EDP received formal notices of both suspended members of the Executive Board of Directors, informing of their unavailability to be re-appointed to serve in EDP’s corporate bodies for the 2021-2023 term of office. On 19 January 2021, an Extraordinary General Shareholders’ Meeting was held, and a new management team was appointed to the Executive Board of Directors, for the 2021-2023 triennium. 

Integrated Annual Report 2022 Financial Statements and Notes 360 EDP reaffirms that no irregularities exist regarding the matters at hand and believes the amounts due by the early termination of the CAEs and the proceedings regarding the DPH, in particular the amounts paid, were fair and according to market conditions. EDP remains determined in the pursuit of its corporate purpose and in the fulfilment of its clients, shareholders, employees, and remaining stakeholders’ highest expectations. EDP is committed to the accomplishment of its strategic goals, and no impact to its consolidated financial statements is expected to arise as a consequence of the above. Regarding the judicial procedure, it is still under investigation and till the present date there are no relevant developments regarding the reason that uphold EDP as a defendant. 51\.

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 385 Organisation and Corporate Governance PART I Information on Ownership Structure, Organisation and Corporate Governance A. Ownership Structure I. Capital Structure 1\. Capital Structure The share capital of EDP – Energias de Portugal, S.A. (Company or EDP) is of EUR 3,965,681,012 and is fully paid up, according to Article 4 of EDP's Articles of Association, being represented by 3,965,681,012 ordinary shares, which have a face value of 1 euro each. The geographical and investor type breakdown of the EDP shareholder structure on 31 December 2022 was as follows: 2\. Restrictions on Share Transferability In the terms of the Articles of Association, the shares are not subject to any limitations in terms of transferability, given that, according to the Portuguese Securities Code, shares traded in the market are fully transferable. 3\. Treasury stock As of 31 December 2022, EDP owned 18,616,167 treasury stock shares, corresponding to 0.47% of the share capital. 8% 8% 34% 15% 36% Breakdown of shareholder structure by geography (%) PORTUGAL SPAIN REST OF EU + UK USA REST OF THE WORLD Source: Interbolsa 95% 5% Breakdown of shareholder structure by investors type (%) INSTITUTIONAL PRIVATE PERSONS 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 386 Organisation and Corporate Governance At the General Shareholders’ Meeting held on 6 April 2022, shareholders resolved on the granting of authorization to the Executive Board of Directors for the acquisition and sale of own shares by EDP and subsidiaries of EDP for an eighteen-month period as from the proposal approved in the General Meeting. 4\. Change of company control EDP has not entered into any significant agreements that come into force, are amended or terminate in the event of a change in control of the Company following a takeover bid, except for normal market practice in terms of debt issuance. In fact, EDP is usually a party in financing agreements and issuer of bonds that include change of control clauses, which are typical set forth in such agreements and securities and are necessary for the completion of transactions, not considering that its existence is likely to harm the economic interest in the transfer of EDP shares, nor the free assessment by shareholders of the directors' performance. 5\. Defensive measures EDP has not taken any measures to prevent takeover bids that would put the interests of the Company and its shareholders at risk. The supplementary rules on this matter remain thus in force. In this regard, it is important to note that, pursuant to Article 14 (3) of EDP's current Articles of Association, votes cast by a shareholder on his own behalf or representing another will not be considered if they exceed 25% of all the votes corresponding to the share capital. Although EDP's Articles of Association impose this limitation on the exercise of voting rights, this limitation is not a measure to prevent successful takeover bids. In fact, the inability of the limitation on voting rights to prevent the success of a takeover bid is the result of EDP's current capital structure and of the compliance of the deliberative quorum of two-thirds of the votes cast, which is set out in EDP's Articles of Association for an amendment to the company agreement on this matter with Article 182 - A (2) of the Portuguese Securities Code. No defensive measures have been taken aimed at or resulting in serious erosion of EDP's assets in the event of transfer of control of the company or a change in the composition of the Executive Board of Directors, thereby prejudicing the free transferability of the shares and free appraisal by the shareholders of the performance of the members of the Executive Board of Directors. 6\. Shareholder agreements According to the Article 7 of EDP's Articles of Association, shareholder agreements regarding the Company must be communicated in full to the Executive Board of Directors and the General and Supervisory Board by the shareholders that have signed them in the 30 (thirty) days following their conclusion. According to information provided to the Company by the shareholders, the Executive Board of Directors is aware of the existence of a single shareholder agreement, which was entered into on 11 April 2007 by Parpública, Caixa Geral de Depósitos, S.A. ("CGD") and Société Nationale pour la Recherche, la Production, Le Transport, La Transformation et la Commercialisation des Hydrocarbures ("Sonatrach"). Although Parpública has sold its shareholdings in EDP's share capital and CGD and Sonatrach do not own a qualifying shareholding in EDP's share capital, according to information at EDP's disposal this does not represent automatic cessation of the effects of the shareholder agreement. EDP has not been informed of any agreement to revoke or amend the said shareholder agreement. In 2021, EDP and Sonatrach agreed to terminate the partnership entered into in 2007, under which EDP assumed full control of the combined cycle natural gas plant, Soto 4, in Spain, with an installed capacity of 426MW, through the acquisition of 25% stake held by Sonatrach, and terminates the commercial relations with Sonatrach that were associated with this partnership. II. Shareholdings and Bonds Owned 7\. Qualifying holdings Pursuant to Article 8 (1) (b) of CMVM Regulation 5/2008, we are providing the following information on qualifying holdings owned by EDP shareholders as at 31 December 2022 and attributable voting rights in accordance with Article 20 (1) of the Portuguese Securities Code.

During 2022, the Executive Board of Directors did not used any of these authorizations. 10\. Significant business relationships between owners of qualifying holdings and the Company In pursuit of its activity and regardless of its relevance, EDP conducts business with and enters into transactions under normal market conditions for similar operations with several entities, beyond which are included qualified shareholders of EDP or companies related to those.

Pursuant to Article 14 (4) of EDP’s Articles of Association, votes for which, under Article 20 (1) of the Securities Code or any legal rule that amends or replaces it, he is responsible will be considered cast by the same shareholder. Pursuant to Article 15 (2) and (3) of the Articles of Association, EDP's shareholders are obliged to provide the Executive Board of Directors, in writing and in a complete, objective, clear, truthful form, and in a manner acceptable to the board, all information that it requests from them on facts concerning them and related to Article 20 (1) of the Securities Code. Noncompliance with this obligation shall result in prevention of the exercise of voting rights pertaining to the shares owned by the shareholder in question. If the limitation on the counting of votes affects a number of shareholders, it will operate in proportion to the ordinary shares owned by each one (Article 14 (5) of the Articles of Association). Furthermore, pursuant to Article 20 (1) of the Portuguese Securities Code, or any legal rule that amends or replaces it, shareholders who become owners of a shareholding of 5% (five percent) or more of the voting rights or share capital, must inform the Executive Board of Directors thereof within five business days of the date on which ownership occurred.

Maximum percentage of voting rights that can be exercised by a single shareholder or shareholders that are related in some of the relations of Article 20 (1) See item 12. 14\. Decisions of shareholders who, under the Articles of Association, can only be made by a qualified majority other than those provided for by law Decisions by the General Meeting are taken by a majority of votes cast, unless the law or the Articles of Association require a qualified majority (Article 11 (3) of the Articles of Association). Article 10 (1) of the Articles of Association defines the performance of functions in any corporate body is incompatible with: • the status of a legal person that is a competitor of EDP or a company in a control or group relation with EDP; • the status of a legal person or an individual related to a legal person that is a competitor of EDP; • the exercise of functions, of any nature or for any reason whatsoever, notably by appointment to a corporate office, by employment contract or by services provision agreement, at a legal person that is a competitor of EDP or at a legal person related to a legal person that is a competitor of EDP; • the appointment, even if only in fact, for a corporate body member by a competing legal person or a person, natural or legal, related to a legal person competing with EDP. Nevertheless, Article 10 (4) defines that the incompatibilities set forth in the foregoing paragraphs may also not apply to the performance of functions as a member of the general and supervisory board, to the extent permitted by law, subject to 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 396 Organisation and Corporate Governance authorization given by prior resolution, with the favour of two thirds of the votes cast at the elective general shareholders’ meeting. The competition relation must be expressly referred to and precisely identified in the appointment proposal, and the authorization resolution may be subject to conditions, notably to a holding of no more than 10% of EDP’s share capital. It should also be highlighted that, according to Article 10 (10) of EDP’s Articles of Association, it should not be deemed to be a competitor of EDP the legal person shareholder that individually holds at least 20% of the share capital of EDP, and that, directly or through a legal person which is in a domain relationship with it, enters into and maintains a medium or long term strategic partnership of business cooperation in the activities of generation, distribution or supply of electricity or natural gas, approved in accordance with legal and statutory provisions, with prior favourable opinion of the General and Supervisory Board. In all other cases, the deliberative quorum set out in Article 383 (2) of the Portuguese Companies Code applies. II. Management and Supervision A) Composition 15\. Corporate governance model EDP's governance structure is a dual model one and consists of the General Meeting, Executive Board of Directors, General and Supervisory Board and the Statutory Auditor. The separation of management and supervision roles is embodied in an Executive Board of Directors, which is responsible for the management of the Company’s business, and a General and Supervisory Board, the highest supervisory body. The division of competences, inherent to such model, between the Executive Board of Directors and the General and Supervisory Board, has been assuring an effective management of the Company, benefitted by a constant and attentive supervision. The dual model of corporate governance in place at EDP since July 2006 has allowed for an effective separation of the Company’s supervision and management in pursuit of the goals and interests of EDP and its shareholders, employees, and other stakeholders, thereby contributing to achieving the degree of trust and transparency necessary for its adequate functioning and optimization. It is also important to note that this governance model has proven to be adequate to the size and shareholder structure of the Company, allowing for constant supervision both by the reference shareholders and by the independent members, through the respective intervention in the General and Supervisory Board. Considering the transversal competences of the General and Supervisory Board and the specificities of the activities of the four Specialized Committees, the integration of members of the General and Supervisory Board and of the Executive Board of Directors of EDP should, according to the Selection Procedure of the members of the General and Supervisory Board and of the Executive Board of Directors, ensure diverse skills, professional experiences, diversity of knowledge, gender and cultures, taking into account the specificities of the Company's business. Along with the concern for the individual adequacy of each member, it is also sought that the composition of the governing bodies and corporate bodies demonstrate a collective adequacy, bringing together the professional and personal skills necessary for the proper performance of the functions of each body of EDP. Likewise, in determining the respective number of members, the size of the Company, the complexity of its activity and its geographical dispersion are considered, in addition to the costs and the desirable speed of operation of the administration. According to Article 11 (2) (b) of the Articles of Association, it is the responsibility of the General Meeting of EDP to elect and dismiss the members of the Executive Board of Directors and the General and Supervisory Board, as well as their Chairmen and Vice-Chairmen, if any, and the Statutory Auditors, based on a proposal by the General and Supervisory Board (or by delegation to the Financial Matters Committee / Audit Committee). The General Meeting also appoints the members of the Environment and Sustainability Board, on proposal of the Executive Board of Directors, and Remuneration Committee of the General Meeting. For a better understanding of EDP's corporate governance, EDP's website allows shareholders and the general public to view the up-to-date Articles of Association in Portuguese and English, the Internal Regulation of the Executive Board of Directors, General and Supervisory Board and its committees, documents that have been modified in order to accommodate best practices, notably the principles and recommendations set forth by the Corporate Governance Code issued by the Portuguese Institute for Corporate Governance. Worth noting also that EDP has since 2010 a Corporate Governance Manual, whose primary objective consists of registering and sharing the provisions of the Executive Board of Directors and of General and Supervisory Board regarding best practices recommendations applicable to EDP on corporate governance. The Manual has a dynamic nature. It should therefore continue to be revised periodically, considering the contributions of all interested parties in the continuous development of EDP’s governance model. 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 397 Organisation and Corporate Governance The Manual for the Corporate Governance of EDP is available to shareholders and general public at its website: Corporate Governance Manual | edp.com. In what concerns prevention and fighting against harassment at work, and complementing the commitments already taken on by EDP in its Code of Ethics, available at EDP’s website, the Good Conduct Code for the Prevention and Fight Against Harassment at Work entered into force as of 21 November 2017 and it is applicable to all EDP Group’s employees. According to this Code, other service providers and suppliers are explicitly required to uphold or adhere to the principles established, in accordance with their obligations under qualification procedures or current contracts. In this regard, during 2022, a new channel for reporting complaints was created, available at EDP's website - Speak Up EDP Channel\- and on the other websites of the applicable EDP Group companies. Additionally, the Integrity Policy approved by the Executive Board of Directors has implemented the mandatory execution to all EDP Group companies as well as to its employees, service providers acting on its behalf, in strict compliance with the legal framework applicable in geographies where the Group is present which aim to avoid unlawful conducts, in particular those associated with the practice of corruption acts, money laundering and terrorism financing. EDP Group is committed to promote an exempt, honest, integrated, professional, and fair action and requires that its employees and contracted third parties behave in accordance with such commitment, complying with the legislation and regulation in force. The EDP Group Companies has implemented and has disseminated prevention, detection, and control measures towards any form of corruption, prevarication, conduct on conflict of interest, influence peddling, money laundering, terrorism financing and other illegal acts. In this regard, the EDP Group Companies may adopt more demanding additional measures, according to local needs, always ensuring the compliance with the local applicable legislation. Additionally, the Compliance & Internal Control which independence is guaranteed through the reporting to the Executive Board of Directors and to the General and Supervisory Board / Financial Matters Committee / Audit Committee of EDP is responsible to biennially review this Policy or whenever any relevant legislative change occurs, submitting those amendments to the Executive Board of Directors for approval. The Integrity Policy of EDP Group was revised in 2022 and is available at EDP’s website: EDP Integrity Policy | edp.com. EDP intends to continue to assume a precursor and excellence role about the promotion of best government practices, in the hope that this initiative may also contribute to enrich the debate on these matters in the general context of the organization and functioning of public limited companies, particularly in Portugal. The EDP Group has been publicly distinguished with several recognitions regarding the behaviours observed in terms of promoting integrity, ethics, and sustainability. Among these recognitions, the following stand out: • The results of the ETHISPHERE ranking, which, since 2012, has considered EDP as one of the “World Most Ethical Companies”; • The Top Employer certification awarded by the Top Employers Institute, in which EDP was assessed on twenty different topics, with particular reference to Business Strategy and Ethics and Integrity, having obtained the maximum score; • A prominent position in the “Codes of Conduct / Compliance / Corruption and Bribery” criterion of the Dow Jones Sustainability Indexes (DJSI), which have presented EDP as one of the most sustainable companies in the world since 2008, integrating the respective indexes (DJSI World and DJSI Europe); • The presence of EDP in the Investment Register of the Ethibel Forum as Pioneer and Excellence, which presents a group of companies that have an above average performance in the respective sector of activity, with the assessment being carried out based on sustainability criteria; • EDP’s presence in the Solactive Global and Europe Corporate Social Responsibility Index based on information provided by Forum Ethibel; • Obtained ISO 37001 (Anti-bribery Management Systems) certification by EDP Energias do Brasil; • Obtained ISO 37001 (Anti-bribery management system) and certification UNE 19601 (Criminal Compliance Management Systema) by EDP Renováveis; • Obtained ISO 37001 certification (Anti-bribery management system) and UNE 19601 certification (Criminal Compliance Management System) by EDP España; • Obtained ISO 37001 certification (Anti-bribery management system) and ISO 37301 certification (Compliance Management System) by EDP. 16\.

Pursuant to Article 9 (1) of EDP's Articles of Association, independence is “absence of direct or indirect relations with the Company or one of its bodies and an absence of any circumstances that might affect impartiality of analyses or decisions, e.g., because the people in question own or are acting on behalf of owners of a qualifying shareholding of 2% (two percent) or more of the share capital of EDP or have been re-elected for more than two continuous or intermittent mandates". In view of the need to clarify the aforementioned Article 414 (5) of the Company Code, as there are diverging legal opinions, Associação de Emitentes de Valores Cotados em Mercado (“AEM”) requested an opinion from the CMVM , whose opinion was that the capacity as independent is only lost if, “on the basis of the criterion of number of terms of office, in a situation likely to affect his/her impartiality in analyses or decisions if the members of the supervisory bodies of public limited companies, having been elected for a first term of office and re-elected continuously or intermittently for a second and third term, are re-elected (for the third time, therefore) for a fourth term of office.” Pursuant to its Internal Regulation, the General and Supervisory Board has in place a specific procedure regarding compliance with a large number of rules on incompatibilities and independence applicable to positions on this board (Articles 7 and 8 of the General and Supervisory Board Internal Regulation). This procedure includes the following aspects: • acceptance of a position as member of the General and Supervisory Board is subject to a written statement setting out specifically (i) the inexistence of any incompatibility under the law or Articles of Association; (ii) compliance with the independence requirements set out in its Internal Regulation, if the person has been elected as an independent member; (iii) the members' obligation to report to the Chairman of the 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 401 Organisation and Corporate Governance General and Supervisory Board or, for the Chairman, directly to the board any subsequent event that might generate incompatibility or loss of independence; • every year, the members of the General and Supervisory Board must renew their statements as to the inexistence of incompatibility and, if applicable, the compliance with the independence requirements. Also, every year, the General and Supervisory Board conducts a general assessment of compliance with the rules of incompatibility and independence by its members. At the same time, the Internal Regulation of the General and Supervisory Board (article 8) has broadened the independence criteria applicable to its members, going beyond the provisions of Article 414 (5) of the Companies Code and Article 9 of EDP's Articles of Association, and so people who directly or through their spouse or relative or similar in a straight line and to the collateral third degree, inclusive, are in one of the following situations cannot have independent status: • being holder, director, having contractual ties or acting on behalf or on the account of owners of a qualifying shareholding of 2% (two percent) or more of the share capital or voting rights in EDP or the same percentage in a company of which it is a subsidiary; • being a holder, director, having contractual ties or acting on behalf or on the account of owners of a qualifying shareholding of 2% (two percent) or more of the share capital or voting rights in a company that is a competitor of EDP; • having been re-elected for more than two consecutive or non-consecutive terms of office; • having exercised for twelve years, on a consecutive or non-consecutive basis, functions in any corporate body of the Company exception made to, from the end of its functions in any body and its new appointment, at least a three-year period has elapsed; • having, in the last three years, provided services or had a significant commercial relation with the Company or one of its Subsidiaries; and, • being a remuneration beneficiary paid by the Company or one of its Subsidiaries other than the remuneration deriving from the execution of its functions as a member of the General and Supervisory Board. The rules of independence covering members of the General and Supervisory Board are particularly important regarding the following requirements: • the board must consist of a majority of independent members (Article 434 (4) and Article 414 (5) and (6) of the Companies Code and Article 21 (4) of EDP's Articles of Association); • the Financial Matters Committee/Audit Committee is composed, at least by, three independent members of the General and Supervisory Board (Article 23 (2) of EDP Articles of Association and Article 3 (1) of the Financial Matters Committee/Audit Committee’s Internal Regulation); • the Remuneration Committee of the General and Supervisory Board must comprise a majority of independent members (Article 27 (1) of the Articles of Association and Article 28 (b) of the General and Supervisory Board's Internal Regulation); • the United States of America (USA) Business Affairs Monitoring Committee must be composed mainly of independent members (Article 3 (1) of the Internal Regulation of the Business Monitoring Committee in the United States of America); • the Corporate Governance and Sustainability Committee must be composed mainly of independent members (Article 3 (1) of the Internal Regulation of the Corporate Governance and Sustainability Committee. In compliance with the above procedure, at the start of their terms of office, the members of the General and Supervisory Board stated that they were not in any of the situations of incompatibility set out in the Companies Code (Article 414-A (1) (a) to (e), (g) and (h) (ex vi Article 434 (4)) and Article 437 (1)) or under Article 10 (1) of the Articles of Association and, where applicable, that they complied with the independence requirements of the Internal Regulation of the General and Supervisory Board and the Articles of Association of EDP (article 9 (1), article 11 (2) (d) and article 21 (4)) . Of the incompatibility situations for the exercise of the role of member of the General and Supervisory Board, pursuant to the Article 414-A of the Companies’ Code, it is considered the exercise of functions of administration or supervisory in five companies. Therefore, one may not be elected or designated a member of the General and Supervisory Board if holds office of administrator or supervisor in five companies. At the end of 2022, the members of the General and Supervisory Board renewed their statements on incompatibilities and on independence. The above statements are available to the public at EDP's website at General and Supervisory Board Incompatibility Statements The independent members of the General and Supervisory Board are shown in the chart in Item 17 above. 19\.

Internal Organisation I. Articles of Association 48\. Rules on amendments to the company’s Articles of Association EDP's Articles of Association do not set forth special rules on their amendment and the general rule set out in 3 Article 386 (3) of the Companies Code therefore applies, i.e., decisions to amend the Articles of Association must be approved at a General Meeting by two-thirds of the votes cast. EDP's Articles of Association may also be amended under the powers of the Executive Board of Directors to move EDP's registered office (Article 2 (1) of EDP's Articles of Association) and increase EDP's share capital (Article 4 (3) and (4) of EDP's Articles of Association) provided that a favourable prior opinion of the General and Supervisory Board is obtained (article 17 (2) paragraph g) of EDP's Articles of Association). II. Whistleblowing 49\. Whistleblowing policy and channels The EDP Group has long pursued a policy of trust and transparency regarding the way it develops its activity and relates to all its stakeholders, making its options clear in this matter, both through the Code of Ethics, created in 2005, and through the Integrity Policy, which define the company's principles and commitments in this area. This policy of trust and transparency naturally includes channels for reporting alleged unethical and/or illegal behaviour, which all stakeholders can use when they consider that the company's ethical and integrity principles may be at risk. In 2022, following the entry into force of Law no. 93/2021, of December 20, which transposed Directive (EU) 2019/1937 of the European Parliament and of the Council, of October 23, 2019, on the protection of persons who report violations of European Union law, and which established the legal obligation to define and implement a reporting channel for any legal person that has 50 or more employees, or who carry out certain activities provided for in the aforementioned Directive, EDP reviewed and updated the channels previously made available, its complaint management process, the procedures resulting from it and the technological support for the reporting channels. In compliance with the new legislation, specific reporting channels were also created (hereinafter “Speak Up” Channels) for each obliged EDP Group company. In this context, the previously existing EDP Ethics channels and the channel for communication of irregularities to the Financial Matters Committee / Audit Committee (FMC/AUDC) of the General and Supervisory Board, were consolidated in the new EDP “Speak up” channel. In the period in which the 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 423 Organisation and Corporate Governance aforementioned FMC/AUDC channel was still active, until June 2022, a complaint was received, and, from the respective analysis, it was concluded that there was no confirmation of any irregularity. In 2022, the analysis of a complaint carried over from 2021 was also completed, also without confirmation of irregularities. The entire complaint management process follows, at each stage, essential guiding principles such as independence, impartiality and objectivity in the analysis and treatment of registered cases, along with the guarantee of absolute confidentiality. Complaints can also be reported anonymously, being guaranteed, notwithstanding this condition, the possibility of interaction with the whistle- blower, as deemed necessary. EDP ensures the protection and non-discrimination of whistle-blowers who make their communications or complaints, in good faith and in a well-founded manner, even if the facts reported are not precise or do not give rise to any disciplinary or judicial proceedings. Any acts of reprimand or retaliation, directly or indirectly motivated by a complaint, causing any damage to the complainants, are not accepted. EDP provides access to the Speak Up channels, through its website, as well as to the respective Whistleblowing Management Regulation, that can be read at: Whistleblowing Management Regulation Speak Up | edp.com III. Internal Control and Risk Management 50\. People, bodies, or committees responsible for internal audits or implementation of internal control systems The EDP Group's Compliance Management System, aligned with the risk management model, is founded on an internal control system based on the “three lines of defence”, in order to properly identify and manage the risks arising from the activity, under the terms of which: • The First line of defence (Business): has, among others, the responsibility for the daily and proactive management of compliance risks, in line with the established regulations. The top management of each functional, business or support unit and all its employees are part of it. • The Second line of defence (Compliance): it has, among others, the responsibility of ensuring business support in the identification, analysis, evaluation, mitigation, and monitoring of risk, as well as challenging and questioning the potential risks that may arise. The main responsibles are the Compliance & Internal Control – Corporate Global Unit, supported by the Compliance Departments of EDP España, EDP Energias do Brasil and EDP Renováveis, and a network of Compliance Partners, Compliance Business Partners and the Local SCIRF (Internal Control over Financial Reporting System) Managers. • The Third line of defence (Internal Audit): it has, among others, the responsibility for carrying out independent audits to the Compliance Management System. These audits may also be carried out by independent external entities with recognized capacity for that purpose. As defined, this model allows the rationalization of resources and efforts, promotes coordination between functions and the homogenization of language connecting all Business Units / Departments through a common infrastructure, sharing the same information systems and processes, and promoting the effective implementation of compliance mechanisms at the different levels of the organization. The compliance function's mission is therefore to promote a culture of compliance and integrity, by identifying relevant compliance risks and by disseminating and coordinating the implementation of mechanisms that promote compliance, providing proactive and systematic advice to the entire organization. The Compliance & Internal Control’s activity is essentially based on four pillars, namely: • identification analysis and assessment of compliance risks; • promotion and coordination of the implementation of policies, procedures, and other control mechanisms, in order to mitigate the identified compliance risks; • monitoring of procedures and other compliance mechanisms adopted, in order to assess the maintenance of their adequacy and effectiveness; • periodic reporting to the Executive Board of Directors and the Financial Matters Committee / Audit Committee of the most relevant topics that may represent a significant risk for the Group. The Compliance & Internal Control also has as main responsibilities to contribute to the improvement of risk management processes associated, in an external plan, with legal and regulatory compliance and, in an internal plan, with compliance with the internal regulations and procedures in force, also ensuring the implementation of the Internal Control over for Financial Reporting System (SCIRF). 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 424 Organisation and Corporate Governance In the performance of its duties, the Compliance & Internal Control reports hierarchically to the Executive Board of Directors and functionally to the General and Supervisory Board, through its Financial Matters Committee / Audit Committee. For its part, the Executive Board of Directors establishes a culture of tone at the top in Compliance matters, approving, disseminating, and ensuring the implementation of EDP's Compliance Management System in line with the Group's strategic objectives. The General and Supervisory Board, through the Financial Matters Committee / Audit Committee, monitors and supervises the implementation of the referred compliance culture and approves the business plan of the Compliance & Internal Control’s activity plan, also ensuring the follow-up of the respective execution. The Group's Compliance Management System, approved by the Executive Board of Directors and by the Financial Matters Committee / Audit Committee, is formalized through EDP’s Compliance Standard, updated in 2022, and is aligned with best international practices, namely with the references of ISO 37301:2021 Compliance Management Systems – Requirements with guidance for use – having EDP obtained the respective certification issued by an external independent entity - and with the COSO (Committee of Sponsoring Organizations of the Treadway Commission) framework for risk management, internal control and fraud prevention (Fraud Risk Management). This system demonstrates the EDP group’s commitment to ensure (i) an adequate identification, assessment, and management of compliance risks, in order to minimize the risk of sanctions, namely financial and possible operational and reputational impacts, and (ii) the confidence of its stakeholders, reinforcing the competitiveness of the EDP Group. The Compliance Management System allows for the harmonization of guidelines and methodologies for compliance management, across the organization and different regulatory scopes, ensuring alignment with other internal policies and procedures, seeking the continuous improvement of the activities developed. Through the work developed over the years, EDP Group's Compliance Management System currently has different mechanisms, such as specific policies and procedures, whistleblowing channels, periodic training / awareness initiatives and monitoring instruments that enable the identification of situations to analyze in a logic of continuous improvement, responding to internal and external challenges. This system is developed at corporate level and covers all activities, businesses, and geographies, defining the organization and functioning model of the Compliance Function and identifying the most relevant specific regulatory scopes, for which the development of a Specific Compliance Program is foreseen. EDP Group adopted a model for structuring its Compliance Management System, based essentially on nine components, which can be classified into three action levels. COMPLIANCE MANAGEMENT SYSTEM Design 1\. Governance model 2\. Risk assessment and management 3\. Policies, Standards and Procedures 4\. Training and Awareness / Communication Implementation 5\. Whistleblowing channels and incident management 6\. Monitoring and testing (internal and external audit) 7\. Report Assessment 8.Implementation of improvement opportunities 9\. Continuous improvement / risk reassessment Based on the defined governance model, the EDP Group's Compliance Management System develops from a risk assessment, which is reviewed periodically or whenever there are material changes in the legal and regulatory context or in the organizational context, and that allows the identification of the compliance obligations or of the most relevant normative scopes for the organization, resulting in the structuring and development of Specific Compliance Programs, through a process that goes through different sequential phases: (i) planning, (ii) conceptual structuring and design , (iii) support for implementation; (iv) monitoring of implementation and (v) ongoing maintenance and continuous improvement. The identification of these most relevant topics is carried out based on the identification and assessment of the legal and other compliance obligations applicable to the activities carried out by the Group, whose analysis is organized into normative blocks (corporate governance, 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 425 Organisation and Corporate Governance energy sector, reporting, environment, health, and safety; information security, among others), resulting in the development of Specific Compliance Programs. At the Specific Compliance Program level, and as a function of specific risks identification and assessment, policies, procedures, and other compliance mechanisms are developed, through which the fundamental principles in compliance management are formalized and detailed control rules and mechanisms implemented, reflecting on the activities developed internally or by third parties on behalf of EDP, and which are key elements for the dissemination of a culture of compliance across the Group. Another fundamental element for the development of Specific Compliance Programs is the training and awareness actions carried out both at the transversal group level and at a specific to certain Business Units or regulatory scope level. The compliance function ensures the follow-up and monitoring of the development, operation, and implementation of Specific Compliance Programs. For its part, and in accordance with the respective annual activity plan, the Audit function conducts specific audit work, addressing compliance topics. In addition, the Compliance Management System and some Specific compliance programs are also subject to independent external review. The results of the monitoring and any recommendations issued by internal and / or external auditing are considered for the purpose of improving compliance management, in a perspective of continuous improvement. The compliance function reports the activities carried out to the Executive Board of Directors and to General and Supervisory Board, through its Financial Matters Committee / Audit Committee. Without prejudice to other mechanisms previously developed, since the definition of the methodological approach to compliance management in the EDP Group, it was possible to structure the different relevant compliance topics at the corporate and local level, being this work reflected in the evolution of the different Specific Compliance Programs, with emphasis among others on the following scopes: • Integrity / Corruption Prevention. The systematization of this Specific Compliance Program had as fundamental element the definition of an Integrity Policy in which the commitments, general principles of action and the duties of the entities of the Group, its employees and business partners were defined, with regard to prevention illicit acts, complementing the set of norms and compliance mechanisms that already exist both at the corporate level (namely the Code of Conduct for Suppliers, the Code of Conduct for Senior Management and Senior Financial Officers, Transaction with Related Parties Policy and the Social Investment Policy, in addition to the EDP Group's own Code of Ethics and the irregularity communication channels made available), as in the different companies of the group, namely the models of prevention and control of criminal liability in EDP Spain and EDP Renováveis and EDP's corruption prevention Compliance program in Brazil (which in turn include a significant set of specific compliance policies and procedures). The EDP Group's Integrity Policy, periodically reviewed (last revision in 2022), is disclosed to all employees (as a mandatory reading document, with record of the respective acknowledgment) and available at EDP’s website reinforces the zero tolerance policy regarding the adoption of practices that could be perceived as acts of corruption or bribery, clarifies the ban on facilitation payments and details the principles related to the prevention of conflicts of interest, donations and sponsorships, contributions to political parties and prevention of money laundering and combating the financing of terrorism, as well as guidelines regarding the performance of third party integrity due diligences, the relationship with politically exposed persons (PPE), the acceptance and assignment of offers and invitations to events and the monitoring of international sanctions. Within the scope of the reporting of irregularities, the principle of non-retaliation is maintained, the different channels available internally and externally and the process of investigating potential situations of non-compliance and the identification and implementation of possible corrective actions are addressed. These principles and guidelines were implemented in specific internal procedures developed within the scope of the Integrity Specific Compliance Program. In 2022, in terms of continuous improvement the following initiatives stand out: (i) the formalization and public disclosure of the Plan for the Prevention of Corruption Risks (covering the companies of the EDP Group in Portugal that are obliged to do so) following the entry into force of the General Regime for the Prevention of Corruption; (ii) reviewing/improving risk analysis methodologies and different internal normatives on Integrity, taking into account changes in context and continuous adherence to best practices and (iii) strengthening the culture of Compliance and Integrity , through the development of training and awareness actions at a global level. The Specific Integrity Compliance Program obtained certification in accordance with the requirements of Standard ISO 37001:2016 – Antibribery management systems – Requirements with guidance for use, both at EDP level 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 426 Organisation and Corporate Governance and at the level of its subsidiaries EDP Spain, EDP Renováveis and EDP Energias do Brasil, certifications issued by independent entities. • Prevention of Money Laundering and Terrorism Financing. As part of the structuring of the Specific Compliance Program for the Prevention of Money Laundering and Combating Terrorism Financing,specific internal regulations and a transversal procedure related to the reporting of suspicious transactions were implemented by the obliged entities and a specific channel is also available for the presentation of complaints in this area, covering the different companies covered by the legal requirements. The obliged companies also proceeded to designate a Responsible for Normative Compliance, according to the legal requirements, whose activity is articulated with the governance model defined in the scope of this compliance program. Throughout 2022, compliance with the applicable legal requirements was ensured, with emphasis on compliance with identification and diligence duties of counterparties with business relationships and/or occasional transactions with EDP group entities subject to the legal regime for the prevention of money laundering. • Protection of Personal Data. This program aims to ensure that EDP Group entities comply with the applicable legal requirements in terms of Data Protection, being supported by a specific governance model, which includes the coordination of the Compliance & Internal Control Global Unit, specific teams with the responsibility for promoting the dissemination, knowledge, training and implementation of the Compliance program in the respective areas of activity and with the Internal Audit in the 3rd line of defense and also and whenever this legal obligation exists, with the figure of the Data Protection Officer. In this context, EDP implemented a Personal Data Protection Policy, available at the EDP website : EDP’s Personal Data Protection Policy | edp.com, with generalized application across all the Group's Business Units, which reinforces the commitments and positioning assumed by EDP in terms of privacy and protection of personal data and defines the principles of action to ensure compliance. This policy thus embodies the company's values and principles, which are also reflected in the different cross-cutting regulations that make up this Compliance Program, which are complemented by specific procedures and control mechanisms defined at the business areas level, in accordance with the respective exposure to Personal Data Protection risks, namely, in its operations, by various privacy policies that govern the processing of data carried out by the different Business Units. Within the scope of the communication and training plans defined annually at the level of each geography, different specific initiatives were carried out and targeted according to the exposure of employees to the risks associated with the processing of personal data. In 2022, in terms of continuous improvement, the following initiatives stand out: (i) the review and update of the Compliance Program Governance Model, with the aim of systematizing and clarifying the main areas of intervention, adjusting some functions and responsibilities; (ii) the process of revising internal Personal Data Protection regulations, with a view to their updating, better systematization and clarification and streamlining of procedures; (iii) carrying out training and awareness actions at a global level and (iv) identifying and implementing improvements to the Personal Data Protection Program Management support tool. • Competition. The Specific Competition Compliance Program aims to reinforce the guarantee of compliance by the EDP Group companies, in Portugal, with the legal requirements in terms of competition, namely regarding contracts signed and the performance of its employees in accordance with the highest standards of ethics and integrity, contributing to the sustainability and development of the markets in which EDP operates. A similar approach to preventing and mitigating practices that potentially restrict competition is being implemented for the rest of the geographies, without prejudice to the codes and manuals already applied. This Specific Competition Compliance Program is, like the others, subject to a continuous improvement scrutiny, having been monitored throughout 2022, with the corresponding review of implemented procedures and control mechanisms. • Prevention of Criminal Legal Risks. The Criminal Legal Risk Prevention Program was implemented in a first phase in companies in Spain (also including a specific program at EDP Renováveis), following different reforms of the criminal law in this country, which introduced and deepened the concept of criminal liability of legal entities with respect to certain crimes, also defining the requirements to be considered when implementing compliance models. The Compliance programs implemented under this scope at EDP, meanwhile extended to other geographies with similar legal frameworks, provide the organization with a management system that includes supervision and control measures to prevent the occurrence of crimes or mitigate the risk of their occurrence, highlighting the issues of prevention of corruption, bribery and other similar offenses (which allows the capture of synergies with other Compliance programs with a transversal scope at the EDP Group level, such as the Integrity Compliance Program). EDP Spain and EDP Renováveis' Criminal Legal Risk Prevention programs are certified in accordance with the UNE Standard 19601:2017 – Criminal Compliance Management Systems, certifications awarded by independent entities. From the established governance model, and with the objective of identifying, assessing, monitoring, and 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 427 Organisation and Corporate Governance controlling the risks to which the EDP Group is exposed, in addition to the Compliance & Internal Control, the Risk and the Internal Audit – Corporate Global Units also play an important role. The Risk – Corporate Global Unit is primarily responsible for coordinating risk assessment studies for the Group, with the aim of supporting the Executive Board of Directors in their control and mitigation and providing integrated risk-return analyses, as presented the respective chapter, which activity is detailed in items 52 to 54 of this Annual Report. In turn, internal audit, formalised in the EDP Group's Basic Internal Audit Standard, revised in 2021, is an objective and independent activity, of guarantee and advisory, aimed at adding value and improving operations of EDP Group, assisting the organization in pursuing its objectives, through a systematic and disciplined approach in assessing and improving the effectiveness of risk management, control, and governance procedures. The internal audit function has the mission of increasing and protecting the value of EDP, providing assurance, advisory and insight, covering several fields of action. The EDP Group's internal audit is a corporate function performed by the Internal Audit – Corporate Global Unit, which has a double dependency, on the one hand administrative structure of the Executive Board of Directors and, on the other, functional of the General and Supervisory Board, to which reports the respective exercise. The EDP Group's Internal Audit are present in Portugal, Spain, the United States of America, and Brazil, depending functionally on Internal Audit . In addition to conducting operational and regulatory audits to Business Units in Portugal and auditing information systems at the Iberian level, Internal Audit’s main duties are to propose audit policies and objectives, in accordance with the law and with the best international practices, ensuring the harmonization of internal audit methods, processes and manuals and with a view to implementing the respective support tools, establishing and managing the systematic planning of internal audits at the Group level. Regarding the areas that make up the Internal Audit, although each area has (operational and regulatory audits and information systems audits) its specific duties, multidisciplinary and the growing interaction between the operational audit and information systems audit teams (with an Iberian scope) have allowed synergies in the analysis of information and data extracted from computer systems to support business processes and, therefore, a better quality of the conclusions obtained, a closer proximity to the business and an increasing monitoring of the degree of evolution of the projects most relevant. On the other hand, Internal Audit’s commitment to quality and the continuous improvement of the processes and activities it carries out led to the creation of the Quality and Continuous Improvement Office at Internal Audit, which, in a fundamentally methodological aspect, ensures an internal service with a view to increasing value added in relation to the internal audit activity in the EDP Group. The Internal Audit Departments, as well as all professionals assigned to this function, govern their performance by the Fundamental Principles for the Practice of Internal Auditing, the Code of Ethics and the International Standards for the Professional Practice of Internal Auditing approved by The Institute of Internal Auditors (IIA). EDP Group has internal auditors experienced in several areas (e.g., finance, accounting, legal, information systems), with a deep knowledge of the Group, allowing a multipurpose and transversal analysis of the issues in question and of the activities carried out. In addition to specific training and experience in the area, the employees assigned to the information systems audit area know the systems implemented in the Group and follow market trends, allowing them to obtain a broad view of the systems and processes with the greatest technological risk. and of greater relevance for the different Business Units. The internal audit activities are developed based on plans aligned with the objectives and mission of the function, in which the audit works that comprise them have as main inputs the consultation with the government bodies and the alignment with the Group's Strategic Plan and with the sustainability objectives, the prioritization of processes based on the risk analysis carried out by Internal Audit, the interactions with the statutory auditor throughout the year and the consideration of topics of interest that it has identified in the scope of the SCIRF audit and the financial audit, international trends and best practices in matters of internal audit, and the identification and assessment of the control environment existing in the various lines of defence that affect each process, in a perspective of Combined Assurance. Internal Audit's lines of activity are the analysis of the effectiveness and efficiency of operations, reliability, and integrity of information, both financial and operational, compliance with internal procedures and standards, compliance with external standards, auditing of information systems and integrity of assets. The changing macroeconomic, social, and political context, as well as the growing technological transformations and the news and changes that have been affecting the energy sector in general and the EDP Group in particular have forced a constant adaptation of the internal audit activity in order to maintain an ability to respond adequately to the challenges 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 428 Organisation and Corporate Governance ahead, aiming to maximize the added value that this activity can and should offer to its stakeholders. Internal Audit has been monitoring the extent and development of the Group's activity in new markets, business lines and geographies, incorporating in its business plan, actions aimed at evaluating and reinforcing the existing internal control environment. The continuous auditing model has evolved consistently, consolidating the methodology, continuing existing audits, implementing new audits to evaluate different business areas, some with real-time analysis, with a set of new indicators and automation of communication exceptions to the audited entity at the time they are detected. It is a robust monitoring and evaluation model, very relevant for the automatic processing of a high volume of data, allowing to obtain efficiency gains in terms of internal control and in the prevention and detection of irregularities. Within the scope of information systems audits, actions have been carried out covering several areas of high criticality, considering, in particular, the digitization program underway at the EDP Group, which has been a lever for strengthening and growing business processes, the increase in processes / activities analysed by continuous auditing and the expansion of routine automation in order to speed up the monitoring of the Group's information systems. In recent years, the existing competencies in the field of information systems and data analytics have been strengthened by recruiting employees who are specialists in these matters in an internal audit perspective, complementing the profiles already existing in the information systems and operational audit teams. The relationship with the various stakeholders is developed, mainly, through periodic meetings with the Financial Matters Committee / Audit Committee and the members of the Executive Board of Directors, interactions with the Business Units, both at the level of the Boards of Directors and with those in charge of the audited areas, interactions with other areas of the Group, such as risk, sustainability, legal advice, human resources, regulation, strategy, management control, compliance, information systems, in order to identify risk areas and to ensure the update on the various matters of the organization. Internal Audit carries out, annually, a process of self- assessment of the Group's internal audit activity, which consists of a reflection and analysis on the structure, composition, skills, relationship, reports, methodologies, DAI procedures and work carried out throughout the year, among others, and includes a global conclusion expressed by the responsible person of Internal Audit's activity in line with the best practices of the function. On the other hand, Internal Audit 's activity and performance is evaluated annually by the Financial Matters Committee / Audit Committee based, among others, on the analysis of the interaction that the Commission develops throughout the year with DAI and on the analysis of information and documentation made available by it regarding the process of its self-assessment. Internal Audit’s activity has been subject to external evaluations since 2010 by the IIA (every 5 years, as established in the International Standards for the Professional Practice of Internal Auditing) and, since that date, the opinion of the evaluation teams has been that the internal audit activity "Generally Complies" with the International Standards for the Professional Practice of Internal Auditing and the IIA Code of Ethics, this qualification being the highest granted by the IIA. The last external evaluation took place in 2020, in all locations where the internal audit function is developed, with the aim of obtaining joint independent certification, with the opinion issued in the external evaluation reports being that the internal audit activity “generally complies” with the Standards and Code of Ethics issued by the IIA in all locations (Portugal, Spain, United States and Brazil), in all its aspects (government, personnel, management and procedures). It is also worth mentioning, and in line with the information described above, the competence of the General and Supervisory Board, which, under legal terms, permanently monitors and evaluates the internal procedures related to accounting and auditing matters, as well as the effectiveness of the risk, the internal control and the compliance management system. This competence is attributed to the Financial Matters Committee / Audit Committee, which is responsible, among other tasks, for permanently monitoring and supervising: (i) financial matters and accounting practices; (ii) internal audit practices and procedures; (iii) the internal mechanisms and procedures of the Internal Control over Financial Reporting System (SCIRF); (iv) matters relating to the risk management and control system; (v) the activities and mechanisms of the compliance management system and (vi) the activity and independence of the company’s Statutory Auditor. 51\. Description of hierarchical and/or functional dependency on other company bodies or committees In the performance of their duties, the Internal Audit administratively reports to the Executive Board of Directors and functionally reports to the General and Supervisory Board that supervises its activity through the Financial Matters Committee / Audit Committee. On the other hand, the Compliance & Internal Control reports hierarchically to the Executive Board of Directors, and functionally to the 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 429 Organisation and Corporate Governance Financial Matters Committee / Audit Committee of the General and Supervisory Board. The Risk Department reports hierarchically to the Executive Board of Directors, without prejudice to the permanent monitoring, by the Financial Matters Committee/Audit Committee, of risk-related matters, as described in item 52 below. 52\. Other company areas with risk control duties The risk management is an integral part of the common practices of business management, and it is the responsibility of all, from the Executive Board of Directors right down to the individual staff member. Each one is responsible for knowing the risks existing in their area of intervention and for managing them in accordance with their role, expertise, and delegated responsibilities. The EDP Group manages its meaningful risks in a portfolio approach, optimizing the risk/ return trade-off transversely across its business areas, aiming to create value and to stand out in the markets where it operates. The EDP Group also works towards a permanent progress of its risk management processes in order to reflect the evolution of its needs and to maintain its alignment with international risk management best practices. The integration of risk management in the most relevant business and decision-making processes is promoted as part of i) strategic development, ii) investment decisions, iii) business plan and iv) operations management, with the purpose of ensuring stability in results and optimize its response to changes in context and opportunities. The risk management process is structured around 3 lines of defence (business operation, risk management/ compliance and internal and external auditing), each led independently and ensuring an adequate level of segregation relative to one another. The functions of risk identification, analysis, evaluation, treatment, and monitoring are followed by a set of bodies with clearly established roles and responsibilities, typified by Group policies that are approved and ratified by the competent bodies of the Group: • The General and Supervisory Board, in particular the Financial Matters Committee/ Audit Committee, is responsible for permanently monitoring the effectiveness of the risk management system, namely in terms of risk identification, assessment, control and management and assessing the degree of internal compliance with the Company's risk management system, continuously monitoring its performance and effectiveness, in articulation with the Executive Board of Directors, namely the risk control policies, the identification of key risk indicators (KRI) and the integrated risk evaluation methodologies, and must evaluate and issue its opinion on the EDP Group's strategic guidelines and corporate risk management policy, prior to their final approval by the Executive Board of Directors. The Executive Board of Directors is ultimately responsible for the decision, supervision and control of risk management, and is responsible for setting the EDP Group's management objectives and policies. In addition to sharing the responsibilities defined for the Boards of Directors, it is also responsible for defining the Risk Appetite set out in the Business Plan, defining the EDP Group's risk policies (in particular, the respective exposure limits by risk category) and for allocating resources in accordance with the risk-return profile of the various options available. • Risk – Corporate Global Unit headed by the Chief Risk Officer, performs a function that is independent from the conduct of business, and supports the Executive Board of Directors at the level of the second line of defense. Its mission is to promote an integrated vision of the EDP Group's risk, ensuring the alignment of risk policies and limits with the appetite defined for the Group, and coordinating risk-return studies at Group level, in order to support the EBD in monitoring and mitigating the main risks. Its main responsibilities are to (i) define concepts, methods, risk measures and key risk indicators (KRI), in accordance with best practices and promoting an integrated and harmonized view of risk in the Group , (ii) update the Corporate Risk Management Policy and Manual, (iii) maintain and update the taxonomy of the Group's most significant risks and promote its implementation in the various Business Units and Corporate Global Units (iv) the promotion and monitoring of the Risk Appetite framework, ensuring consistency with strategy, and monitoring and reporting of conclusions and possible non-compliance to the EBD , (v) the identification and reporting of needs to define new policies, limits or adjustment to the exposure limits already established by the EBD, (vi) the development, jointly with the Business units and Platforms risk-officers, of significant risk assessment projects and risk-return analyses, (vii) the quantification and qualification of the materiality of BU or platform risks, (viii) the interlocution and adequate information flow to and from the local risk-officers, decision making bodies and other relevant stakeholders on all relevant risk related matters, (ix) the promotion of the monitoring process of the main risks (recurrent and structural monitoring) and reporting to the EBD on the evolution of their level of exposure and contrast with established limits, and finally (x) the promotion of a Group-wide risk management culture. • The risk-owners of the Business Units and Corporate Global Units are all the business managers who assume risk in their day-to-day activities and act in accordance with the defined risk strategies. From a risk perspective, they should coordinate their activities with 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 430 Organisation and Corporate Governance the risk-officer of the Business Unit/ Platform, and are responsible for (i) implementing mitigation measures and treatment plans in accordance with what is defined in the risk policies, (ii) monitoring the risk indicators defined (KRIs) by RISK, reporting on their evolution and providing visibility to the risk-officer of the Business Unit/ Platform whenever there is or there is anticipated behavior that could compromise the defined risk strategy, (iii) collect and report risk information to the risk-officer, within the scope of their activity, in accordance with recurring activities (risk maps, reports, etc.) or whenever necessary. • Local structures for risk management (risk-officers) assume a key role on operationalizing risk management, typically under the direct hierarchical dependence of the respective Board of Directors, with functional coordination with the Group's Chief Risk-Officer, acting in a segregated manner and independent from business operation. In large and/ or particularly complex Business Units local replicas of risk management corporate structure exist, articulated with the Risk. Their responsibilities include: (i) following the risk management methodology defined for the Group, (ii) identifying the main risks (threats and opportunities) within the scope of the activity, in close articulation with those responsible for the business, (iii) characterizing the main risks, with quantification and qualification of their materiality (iv) to escalate material risks to its Board of Directors and Risk - Corporate Global Unit, (v) to carry out studies on the main strategic themes and associated risks, in close articulation with those responsible for the business and Risk - Corporate Global Unit, (vi) to support its Board of Directors in taking strategic decisions from a risk perspective, (vii) to propose or issue opinions on ways of mitigating or hedging the main risks, including, where applicable, defining risk management policies, risk treatment guidelines and risk limits, in liaison with the Risk - Corporate Global Unit (viii) to follow up and monitor relevant risks through the preparation of periodic reports on risk exposure and disclosure to the decision-making bodies and Risk - Corporate Global Unit, as well as monitoring the implementation of risk management policies, standards and procedures, including the monitoring of exposures in relation to the established limits, (ix) to coordinate the holding of Risk Committee meetings (x) ensure the interlocution and the adequate flow of information to and from the Risk - Corporate Global Unit, decision making bodies and other relevant stakeholders in all relevant risk related matters. 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 431 Organisation and Corporate Governance Model for risk function report at EDP Group (and communication with the corporate centre) Furthermore, there are several regular forums for the discussion, analysis, and issue of opinions on risk-related topics: • The main objective of the EDP Group’s Risk Committee is to support the decisions of the Executive Board of Directors in the identification, analysis, evaluation, treatment and monitoring of risk, in terms of (i) supporting the identification of significant sirks and the characterization of the EDP Group risk profile, (ii) to discuss the results of significant risk analysis and evaluation projects developed in conjunction with the Business and Corporate Global Units, (iii) to propose and issue opinions and/or recommendations on significant risk management strategies (e.g. policies, procedures and limits) for appraisal and approval by the Executive Board of Directors, and (iv) to monitor and control the evolution of significant risks. This Committee meets periodically and, whenever necessary, extraordinarily, preferably at least quarterly. The Committee is composed of the Group's main decision-makers and risk managers (members of the Executive Board of Directors, key corporate areas and members with responsibility for risk management of the main platforms/ geographies). • The Individual Risk Committees are created and conducted at the Group's Business Unit level when the degree of complexity of risk management justifies it, assuming a structure replicated from the Group's Risk Committee. These committees are typically coordinated by the respective risk-officer and include members of the Board of Directors, key areas of the Business Unit, as well as a member of the Risk - Corporate Global Unit, to ensure alignment at the Group level. 53\. The main types of economic, financial, and legal risk to which the company is exposed in its business The EDP Group's risk taxonomy aggregates, from an integrated perspective and in a common language, the various risk mappings existing at the level of the Group's various Business Units, and is structured around four major families: strategic & ESG, business, financial and operational. Taxonomy of risks of the EDP Group 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 432 Organisation and Corporate Governance In 2022, the conflict in Ukraine resulted in a geopolitical and energy crisis with a transversal impact on strategic & ESG, business, financial and operational risks. In particular, for EDP Group, the main impacts were at the business level, with the increase in gas and energy prices, at the regulatory level, with the introduction of clawbacks on infra-marginal technologies, and at the financial markets level, with the increase in the cost of debt. Additionally, hydro power generation was substantially below average due to lower rainfall in the Iberian Peninsula. Strategic & ESG risks The EDP Group closely monitors and reports on strategic risks, since it considers that these risks may have a significant impact if they occur. The strategic & ESG risks can be broken down into two different types: • Strategic risks, associated with strategic developments that could translate into a material negative impact for the Group, of a predominantly emerging nature. Examples of this type of risk are the risks of social and political crisis in the main geographies in which the Group operates, technological disruptions of various kinds, disruptive changes in the competitive paradigm and geopolitical risks. • In terms of the risk of social and political crisis, the presence in various countries leads to greater exposure to risks related to political instability and discontent/ social crises, motivated by challenging macroeconomic/ political situations. These risks may impact the EDP Group, for example, from increases in volatility in the financial markets and regulatory risk. • In terms of technological disruptions, the EDP Group has sought to position itself at the forefront of technological development in the sector, viewing this issue not as a threat but as a central vehicle for promoting growth in the future. In this sense, the EDP Group has invested and researched actively and transversally in the promotion of new technologies in the various stages of the value chain (namely at the level of the activity of EDP Inovação, and the Digital Global Unit). • In terms of disruptive modifications to the competitive paradigm, the Group recognises risks associated with alterations in the paradigm of the business model (for example, in terms of distributed generation). The EDP Group addresses this risk through rigorous analysis and prospective investments, allowing it to anticipate and proactively adapt its business model to possible market evolution trends. • In terms of geopolitical risks, the Group recognizes the risks arising from the relationship between two countries, which may result from various factors, including commercial exchanges, military or political activity. Geopolitical tensions may have relevant impacts at the level of instability of energy and financial markets, counterparty and supply chain risks, among others. • ESG risks, associated with environmental, social, governance and other transversal ESG risks. • At the environmental level, the Group is exposed to risks related to climate change (physical risks and opportunities, e.g. temperature rise and reduced precipitation, and transitional risks, e.g. market and technological risks), risk of impact of its activity on the loss of nature and biodiversity (e.g. pollution and threat to protected species) and circular economy (e.g. scarcity of raw materials and waste management). • At the social level, the Group is exposed to a number of risks in its relationship with its employees and society: people risks (including employee welfare risks, management of employee talent and human rights violations), impact of the company's activities on communities (including risks of engagement with local communities and economies and economic inclusion), and security and asset and service quality risks (including service quality, customer satisfaction, security and data privacy and security). • At the governance level, the EDP Group is exposed to two categories of risk: risks of inadequate corporate governance (including executive compensation, governance bodies and strategic alignment) and risks of business and ethical misconduct (including fraud and unethical behavior). • Transversal ESG risks are considered to be risks that are not exclusively environmental, social or governance issues, but are transversal in nature, namely potential misalignment of ESG practices and direct/ indirect non-compliance with ESG commitments by counterparties, such as customers, suppliers, partners and financial or energy counterparties, impacting EDP's reputation. Additionally, risks associated with company communication, through external means such as the media, and internal such as departmental decisions, in misalignment with signed commitments, which may imply an adverse reputational impact for the company. Business risks Business risks include all risk factors intrinsically linked to the remuneration of the EDP Group's core business in energy generation, trading, distribution and supply in the various 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 433 Organisation and Corporate Governance countries and markets in which it operates. The business risks can be broken down into two distinct types: • Energy market risks, related to electricity prices (pool) and other commodities, renewable energy generating volumes (hydro, wind, and solar power), energy consumption (associated with demand) and supply margins. • Regarding price of electricity, the impact is limited by the fact that a significant part of the generation is long term contracted, mainly at EDP Renewables and most of the installed capacity in Brazil. Currently, (i) all generation in Portugal and Spain under the ordinary regime, (ii) generation in Brazil in excess or in deficit of the PPAs and (iii) part of EDP Renewables'1 wind farms in Spain, United States, Poland and other geographies are subject to market price fluctuations. Global Energy Management (GEM) is responsible for acting proactively in the spot and forward energy markets (both organized markets and over-the-counter) to optimize the market production margin and limit the respective risk, in accordance with clearly established delegated responsibilities and ensuring periodic P@R - Profit at Risk - reports, based on a proprietary model. GEM's performance is duly framed by a specific risk policy, including exposure limits. • The price of other commodities (essentially fuels and CO2 ) subject to fluctuations resulting from supply and demand dynamics or changes in international legislation and relevant only to power plants subject to the market, is monitored and managed proactively by GEM, which negotiates and manages coal and gas contracts and CO2 licenses, and is also responsible for mitigating, via hedging, fuel price risk (including exchange rate risk 1 Annual Wind Energy Ratio versus Annual Benchmark in US dollars, in coordination with Finance - Corporate Global Unit). • In terms of renewable energy generation volumes, the EDP Group has a material degree of exposure, particularly with respect to hydro volumes (the Wind Yield Index1 and Solar Yield Index2 tend to be less volatile than the Hydro Yield Index3 , on an annual basis), resulting from its commitment to a portfolio of increasingly renewable generation, as well as its hydro portfolio in Portugal and Brazil. Although this risk can introduce a certain annual volatility in the results, it has a significantly lower impact in the long term on EDP's generation portfolio, since (i) there is an inter- annual diversification of the risk, (ii) there is technological diversification, with a volume versus price compensation with the other technologies in the Group's portfolio (a lower hydroelectricity output is partly compensated by higher thermal generation and an upward trend in the pool price) and (iii) it is a risk with little market correlation. On the other hand, in Brazil, the exposure is significantly mitigated by the fact that (i) there is a diversification of hydroelectricity throughout the territory (through financial coupling mechanisms), (ii) there is a PPA on established firm energy, as well as (iii) the Group has adhered at the end of 2015, to the hydrological risk re-pricing mechanism which, combined with the price ceiling of the Settlement Price for the Differences (PLD), allows limiting the exposure to the deficit of allocated energy in relation to the energy sold in PPAs (for the regulated contracting environment). • Regarding energy consumption (electricity and gas), the EDP Group is subject to fluctuations in the amounts of energy sold depending, among others, on factors such as economic activity and annual 2 Ratio of Annual Solar Energy versus Annual Reference temperatures, as well as extraordinary events (such as the COVID-19 pandemic in 2020). Besides such economic cycle fluctuations and energy efficient solutions, consumption can also be affected by situations of rationing (as happened in Brazil in 2001). Given the difficulty to mitigate these risks, EDP chooses to manage them through diversification across multiple technologies, countries and business lines. • Regarding sales margins, the current customer migration to the free market enhances the competitiveness of offers from suppliers and can add additional volatility in terms of market shares and unit margins. Moreover, there is risk associated with deviations in actual consumption from the forecasting model adopted by the Group. These risks are managed by the Group's energy sales companies, with particular emphasis on initiatives to i) strengthening the core offer (e.g., through combined electricity and gas products); and ii) introducing innovative products and services (e.g., Funciona and Re:dy). In addition, a team dedicated to the prices and volumes matters evaluates and regularly makes recommendations for the dynamic management of this risk. • Regulatory risks, related to changes in legislation and regulations that the Group is required to comply with in the various countries and markets in which it operates (in particular, but not limited to, sectoral packages, regulatory frameworks, environmental legislation, and taxes, and other). This risk is managed proactively by the EDP Group, through monitoring and thorough preparation of the various dossiers and adopting a constructive and cooperative attitude in their discussion. This allows the materialization of options out of synch with reality in the different market contexts in 3 Annual Hydro Power Ratio versus Annual Reference 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 434 Organisation and Corporate Governance which the Group operates to be anticipated and minimized. Financial risks The financial risks encompass the market risk factors linked to the (non-operational) energy business of the EDP Group in the various countries and markets where it operates. Financial risks can be divided into four different types: • Financial markets risks, associated with fluctuations in international markets in interest rates, exchange rates, inflation and valuation of financial assets held by the Group. • Regarding interest rates, the risk is mainly associated with the percentage of debt at floating rates, as well as any increases in costs associated with fixed rate debt refinancing needs in a context of rising current interest rates. This risk is managed and mitigated by the Finance - Corporate Global Unit, which ensures compliance with the established risk profile, using the procedures and instruments provided for in the Group's policies, with periodic reports being prepared on the evolution of these variables and risk sources. • Regarding foreign currency exchange rates, the risk is associated with fluctuations in the cost of the purchase and sale of electricity and fuel, as well as with fluctuations in the value of net assets, debt and income generated in currencies other than the Group's functional currency. The EDP Group acts proactively to ensure a balanced net structural exposure (assets - liabilities) in US Dollars, British Pounds Sterling and Canadian Dollars. On the other hand, the geographical diversification of the Group's businesses (and corresponding exposure to multiple currencies) contributes to reducing volatility in the annual result. The remaining risk is managed and mitigated by Finance - Corporate Global Unit, in conjunction with GEM, EDP Renewables and EDP Brazil, in the same way as above. • Regarding inflation, the risk is mainly associated with the fluctuation of revenues and operating costs in the various countries where the EDP Group operates. In terms of its mitigation, the remuneration models of the regulated activities, as well as part of the PPA contracts, include inflation indexation components in order to preserve an adequate remuneration to the activity. On the other hand, a significant component of the Group's current activity is focused on markets with more stable inflation levels. For the remaining risk, in addition to active management of the various supply and services contracts, the EDP Group addresses this risk from an integrated standpoint, mitigating it by means of a debt profile (fixed/variable rate) aligned with the respective revenue profile. • Regarding the valuation of financial assets, EDP adopts a conservative risk policy with reduced levels of exposure, based on a reduced weight of strategic financial assets and short-term cash investments mainly based on bank deposits (without market risk). This risk mainly results from the possibility of devaluation of the financial assets that EDP holds (traded on securities markets). It is managed according to the procedures and tools provided by the Group's risk policies. • Counterparty and credit risks, associated with unexpected changes in the compliance capacity with obligations by customers, financial counterparties (mainly associated with deposits in financial institutions and financial derivatives) and energy counterparties. • Regarding financial counterparties, this risk is managed through: i) a careful selection of counterparties; ii) an appropriate diversification of risk over multiple counterparties; iii) an exposure based on financial instruments of reduced complexity, high liquidity and of a non-speculative nature; and iv) regular monitoring of the positions held. • Regarding energy counterparties, this risk is reduced for the operations in organized market, being that, for the operations in over-the-counter market and for the fuel purchases, GEM, responsible for the follow-up and interface with the wholesale markets, carries out the respective follow-up through the application of exposure and trading limits previously established and approved by a superior level, according to the counterparties' rating (external whenever possible, or internal if the previous one is unavailable), as well as the use of clearing houses. Similarly, there is also counterparty risk associated with long-term energy sales contracts, partially mitigated by the fact that some of the counterparties in this context are sovereign entities (Governments or State Electric Systems), while strict scrutiny and approval criteria are also applied to private counterparties. • Regarding customers, the Group is exposed to default risk in Portugal, Spain, and Brazil. The average level of risk in Spain is structurally mitigated in terms of expected loss due to a mix of customers with greater weight of the B2B segment (which has less relative weight of average default). The risk in Brazil is mitigated through financial collateral to mitigate the loss (for the Free Contracting Environment), and through the partial recovery of non-compliance by the regulated tariff (for the Regulated Contracting Environment). This is monitored by E-Redes and EDP Comercial (in 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 435 Organisation and Corporate Governance Portugal) and EDP España, which are responsible for carrying out the meter reading cycles and cutting off the service/taking legal action and debt recovery. In addition, mitigation tools such as credit insurance, credit risk premium and setting up bank collateral are used, whenever this is deemed necessary. • Liquidity/solvency risk, associated with specific cash shortfalls, difficulties in access/ cost of credit and rating reduction risk. • Regarding possible sporadic cash shortfalls, there is a risk of possible default of the EDP Group in meeting all its short-term liabilities in the committed time periods, or just being able to do so under unfavorable conditions. This risk is mitigated through careful liquidity management, by means of: i) centralization (cash pooling) of all the Group's liquidity at the holding company except for Brazil; ii) keeping adequate levels of liquidity (cash and firmly committed credit lines) based on detailed forecasting of cash requirements (reviewed in 2016 to cover two years of refinancing); iii) an appropriate strategy to diversify funding sources; and iv) the diversification of debt type and maturity profiles. • Regarding access to and the cost of credit, the EDP Group has achieved, despite the adverse economic context, all funding necessary for the usual roll over of debt and to finance the Group's business. EDP's Group has successfully continued with its strategic commitment to reduce leverage (expressed as Net Debt/EBITDA excluding Regulatory Assets) over forthcoming years. Additionally, the Group has acted towards increasing the average maturity of its debt and reducing its average cost. • Regarding the risk of a ratings decline, the EDP Group can be impacted in its access to and cost of financing by adverse changes in its rating profile (assigned by international agencies). EDP proactively manages this risk by maintaining a low risk profile and maintaining stable contractual standards, which assure that its liquidity position does not depend on mechanisms as financial covenants or rating triggers. • Social liabilities' risk, associated with obligations relating to the capitalization of the Defined Benefit Pension Fund of the Group for Portugal, Spain and Brazil (which has a risk associated with the market value of its assets), and additional costs associated with early retirement as well as medical expenses. The liabilities for employee social benefits are calculated annually by an Independent Actuary on the basis of IFRS-IAS assumptions (taking various factors into account, including interest rate, demographic aspects, economic variables and the applicable requirements). The Defined Benefit Pension Fund is regularly monitored by the Pension Fund Committee that meets at an established frequency, in terms of the value of its assets and the variations in terms of its liabilities (e.g., actuarially related). Operational risks The operational risks encompass the risk factors other than those linked to the energy and financial business of the EDP Group in the various countries and markets where it operates, associated with the planning, construction and operation of physical assets, implementation of processes, systems and legal litigation and compliance. The operational risks can be broken down into five different types: • Physical assets risks, related to unforeseen occurrences in projects under development/ construction, damage to physical assets in operation and (technical and non-technical) operating losses, associated with the operation of the assets (mainly in distribution). • Regarding projects under development/ construction and assets in operation, the EDP Group is exposed to incidents derived from external causes (e.g., atmospheric phenomena, fires, damage to structures, assaults or thefts, environmental pollution) or internal causes (e.g., or installation), which may translate, among others, into threats to the physical integrity of the Group's employees or third parties, equipment repair or replacement costs, unavailability of assets and consequent loss of profit or compensatory damages to third parties. These risks are, firstly, managed and mitigated by the various operational areas of the Group's Business Units, which jointly propose and implement best practices at the level of various policies, standards and operating procedures, inspection and regular preventive maintenance, as well as crisis management and business continuity plans for catastrophic events. Secondly, a significant part of the remaining risk is mitigated through a comprehensive set of insurance policies (essentially at the level of property damage, civil liability and environment), ensured in an integrated manner through a dedicated area - the Insurable Risks Unit of EDP Global Solutions. This approach ensures consistency of risk management policies and dissemination of best practices, as well as strengthening the Group's negotiating position. The insurance policies in force contribute to relevant mitigation of the impact of major incidents (e.g. those associated with extreme and wide-ranging 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 436 Organisation and Corporate Governance atmospheric phenomena, revenue unavailability of generation assets or relevant compensation to third parties), as well as very low-frequency incidents of catastrophic impact (e.g. earthquakes). • Regarding operating losses, the EDP Group is, firstly, liable for regulatory penalties if it does not meet the objectives set for distribution efficiency (technical losses) and also, on the other hand, for the loss of revenue associated with increased consumption of non-invoiced energy (non- technical losses). The various energy distribution Business Units (E-Redes, EDP España, Espírito Santo and São Paulo) are responsible for this risk. Programs are continuously developed to monitor and mitigate this risk (including the launch of comprehensive programs to combat fraud). • Process execution risks, associated with irregularities in the implementation of various processes (particularly, but not limited to, commercial activities, supplier selection and management, billing and collection from customers, planning and budgeting of activities). This risk is monitored by the various Business Units. Its mitigation regarding financial reporting is controlled through the group-wide Financial Reporting Internal Control System (SCIRF), which systematically assess both quantitatively and qualitatively the existence and adequacy of the design and documentation of the various existing processes, as well as their internal control mechanisms, based on annual cycles. • Systems risks, associated with both the non- availability of information systems, as well as failure in the integrity and security of their data, due to a growing sophistication and integration of the several informatic systems and technologies. These risks are managed by dedicated areas within each the Business Unit (centralized in the Digital Global Unit for Portugal and Spain). To mitigate IT risks, there were established in collaboration with Business Units (end-users) critical levels and maximum unavailability timings allowed for each key application. Disaster recovery redundant systems have also been sized and implemented to address the business specifications (particularly strict for critical systems related with, for example, the implementation of financial transactions, communication and grid operation and trading of energy). Business Units with operational information systems (i.e., EDP Produção and E-Redes) have specialized teams to guarantee the security and integrity of systems. Additionally, regarding cyber security, a number of mitigation measures have been developed, namely i) the creation of a Security Operations Centre (SOC) dedicated to the continuous monitoring of the security of IT/ OT infrastructures, ii) the creation of a cyber range to simulate and test the reaction of employees in case of cyber-attack, iii) insurance coverage of cyber risks, and iv) the development of training and other awareness initiatives about the key principles of information security. • Legal and compliance risks, associated with losses arising from non-compliance with existing tax, labour, administrative, or civil legislation, or any other, that has an economic (penalties, compensation and agreements) and reputation impact. EDP Group analyses, monitors, and reports the aggregate exposure and material developments to all relevant bodies, whether at the level of the Board of Directors or the General and Supervisory Board. In addition to overall exposure and by country, all cases deemed to be of a material nature (contingency over EUR 2.5 million) are collected, analysed, and reported individually. All ongoing processes are evaluated and classified individually by legal advisors as probable, possible, or remote, according to their probability of resulting in a negative impact on the EDP Group. The Executive Board of Directors of EDP and the Boards of Directors of its subsidiaries, based on the information provided by legal advisors and on the analysis of pending lawsuits, recognizes provisions to cover the losses estimated as probable, related with litigations in progress. This treatment includes not only ongoing disputes (litigation in courts and out-of-court), but also the main contingencies in dispute and not materialized (and which may also translate into a negative impact, through the materialization of a dispute). • Regarding potential unethical conduct by employees or other associated entities, the EDP Group provides regular training (for all employees) on ethical models of action and behaviour in case of transgressions in the ethical field. This risk is monitored by the EDP Group's Ethics Ombudsman Office, an internal structure responsible for collecting, analysing and assessing, in the Ethics Committee, all allegations of unethical behaviour, under strict conditions of confidentiality and protection of the respective sources. In addition, the EDP Group's Ethics Committee is responsible for defining lines of action to mitigate and sanction unethical behaviour, whenever necessary, according to the facts collected and reported by the Ombudsman. Risks associated with non-compliance with processes or corruption are also monitored by the Compliance & Internal Control. 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 437 Organisation and Corporate Governance 54\. Identification, analysis, evaluation, treatment, and monitoring of risks Given the size of EDP Group and its geographical diversity, it is important to define a common process for all Business Units that recognizes and manages the heterogeneity of businesses and activities in which the Group operates. Accordingly, risk management in the EDP Group can be divided into five major integrated and structured phases (identification, analysis, evaluation, treatment, and monitoring), complemented by a previous phase of establishment of context, and adequate levels of communication between all stakeholders: • The identification of risks refers to mapping and updating the main risks associated with the Group's activity, as well as representing them in a structured repository - the taxonomy of risks. This exercise is, in the first place, the responsibility of each of the Business Units and Corporate Global Units within their respective scope, and the Risk - Corporate Global Unit, in coordination with the respective risk-officers, is responsible for validating and integrating the various exercises in a general repository (at the EDP Group level). In this sense, a mapping of the EDP Group's main risks in relation to the budget and/or business plan, of the main emerging risks, and of the climatic risks (in accordance with the TCFD recommendations) complemented by local exercises in some Business Units, is carried out on a recurrent basis. More recently, the EDP Group's risk taxonomy was revised to guarantee the inclusion of ESG risks in a structured manner, and complemented by a specific taxonomy of ESG risks with greater detail, thus promoting the adoption of a common language and facilitating the structuring of the various risk identification exercises carried out in the scope of specific risks and/or or Business Units. • The analysis of risks is related to the establishment of criteria to evaluate the nature and materiality of risks, as well as the analysis of the respective individual and aggregate exposure in accordance with the defined criteria. This exercise is, in the first place, the responsibility of each Business Unit and Corporate Global Units within their respective scope, and it is up to the Risk - Corporate Global Unit, in coordination with the respective risk-officers, to support the respective execution, namely through the development of adequate methodologies. This standardization and systematization of analysis and assessment criteria enables risks of heterogeneous natures to be compared, to inform the various decision-making bodies about the relative orders of magnitude of the various risks, and to guide the prioritization of management and mitigation actions, as well as the definition of clear risk management policies at various levels (including the definition of limits). In addition to the isolated analysis of individual risks, risk-return analyses and quantitative risk maps (based on EBITDA@Risk, Cash-flow@Risk or other methodologies) are also systematically carried out, supporting the Group's main strategic decisions and guidelines (for example, at the level of the Group's Strategic Plan, investment decisions). • The evaluation of risks consists of comparing the risk profile with the Group's risk exposure appetite (explicit or implicit), as well as the consequent definition of adequate strategies for the respective treatment, when necessary. This exercise is the responsibility of the Executive Board of Directors and the various Business Units, supported by the respective risk-officers, who act in articulation with the business management (risk- owners) and with the Risk - Corporate Global Unit, led by the Chief Risk-Officer. In this 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 438 Organisation and Corporate Governance sense, we should highlight the formalisation of a risk appetite for the EDP Group, which simultaneously serves the external purpose of structuring a holistic narrative articulated around the strategic pillar of controlled risk for the EDP Group, as well as the internal purpose of promoting reflection on strategic options of risk-return trade-offs. • The treatment consists of the appropriate implementation of the risk strategies previously established, including the definition of adequate control mechanisms. This exercise is the responsibility of each of the Business Units and Corporate Global Units, within their respective scope. • The monitoring ensures the effectiveness of action on identified risks, both with regard to control and periodic reporting of the position in terms of the various risk factors, and with regard to the effective implementation of policies, standards and procedures established for risk management. This exercise is the responsibility of the Executive Board of Directors and the Group's various Business Units. The Risk - Corporate Global Unit and the risk- officers of the various Business Units are responsible for promoting and stimulating risk management and control activities, disseminating best practices and supporting the dissemination of concepts, methods, risk measures and key risk indicators (KRI). Additionally, Risk - Corporate Global Unit and the respective network of risk-officers develop a set of management information reports at defined intervals, disclosed to the Executive Board of Directors and to the Boards of Directors of the various Business Units. These reports allow the organization to regularly track KRIs that are aligned with performance metrics and, as such, mirror the risk profile at each moment. Additionally, these indicators are subject to risk limits in turn aligned with the objectives and strategy of the EDP Group, thus allowing this to be implemented at the operational level. This information and the evolution of the company's risk profile are also reported to the General Supervisory Board, through the Financial Matters /Audit Committee, namely through the Risk Appetite dashboard that is shared quarterly. 55\. Main features of the risk management and internal control systems in place in the company for the disclosure of financial information EDP Group has implemented the Internal Control System of Financial Reporting (ICFR), based on criteria established by the regulatory framework of internal control issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO 2013), in relation to business processes and entity level controls, and the Control Objectives for Information and Related Technologies (COBIT), in relation to the general controls of information technology.

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 442 Organisation and Corporate Governance Remuneration Committee to be appointed by the General Shareholders’ Meeting – Item 11 of the Agenda | edp.com III. Remuneration Structure 69\. Remuneration policy of management and supervisory bodies Executive Board of Directors The Executive Board of Directors' Remuneration Policy ensures a (fixed) base remuneration, the payment of which is not dependent on performance evaluation, which must be fair, competitive, and sufficiently relevant in relation to the total remuneration, in order to allow greater flexibility in the conformation of the variable component of the remuneration. The Remuneration Policy of the Executive Board of Directors comprises a variable remuneration, with an annual component, and a multi-annual component, with the nature of reward/incentive appropriate to the individual and collective performance of the members of the Executive Board of Directors and the promotion of good conduct, taking into account EDP's short- and long-term, financial, and non- financial objectives that are achieved, and the way in which they were achieved (pay for performance). The annual variable component is linked to financial and non-financial objectives established in accordance with EDP's Annual Budget, measured annually, with an impact on the year and subject to evaluation and consequent repercussion in the following years, being paid in cash. The annual variable remuneration must be determined after the approval of EDP's accounts at the Annual General Meeting each year, by reference to the previous year/period of annual performance. The payment of multi-annual variable remuneration is partially deferred. The multi-annual variable component is linked to the quantitative and qualitative objectives of EDP's Business Plan, the fulfilment of which will be evaluated at the end of a period of three years, with the respective payment subject to partial deferral. The multi-annual variable remuneration is paid exclusively in shares representing the share capital of EDP. The determination of the variable annual and multi-annual remuneration of the members of the Executive Board of Directors in accordance with the Remuneration Policy is the responsibility of the Remuneration Committee of the General and Supervisory Board. The payment of the variable remuneration is subject to the permanence of the member of the Executive Board of Directors at EDP until the end of the annual or three-year period of relevant performance, without prejudice to the provisions of the Remuneration Policy. The Remuneration Policy approved at the General Shareholders’ Meeting held on 14 April 2021 determines therefore the following: • Fixed remuneration \- The base remuneration of the members of the Executive Board of Directors must be aligned with the base remuneration practiced by a group of companies comparable with EDP, of the national market (PSI 20 Index) and of the international electricity sector, in terms of size, market capitalization, risk profile, relevance and geographic implantation, also considering, at all times, the complexity of the functions performed, the remuneration conditions of EDP workers and the non-increase of the average remuneration gap of the market between workers and managers. Considering the reduction in the number of members of the Executive Board of Directors and the organizational / functional review of the same with the consequent increase in responsibilities resulting therefrom, in particular the lower overall remuneration level of the Executive Board of Directors, the Remuneration Policy in force has eliminated a remuneration level in the Executive Board of Directors, reducing, compared to the previous Remuneration Policy, from three to two, the levels of remuneration of the members of the Executive Board of Directors, under the following terms: (i) annual base remuneration of the CEO: 800,000.00 Euro; and (ii) annual base remuneration of the other members of the Executive Board of Directors: 560,000.00 Euro. The base remuneration of the members of the Executive Board of Directors is paid in 14 monthly instalments. • Annual variable remuneration \- The maximum annual variable remuneration may not be higher than 80% of the base remuneration in force in the year to which the referred annual variable remuneration refers, being determined, and falling due, after the approval of accounts for the year to which it relates. The annual variable remuneration has the nature of an incentive / performance bonus linked to short-term financial and non-financial objectives (linked to the business plan and budget), analysed annually, with a reflection on the year under evaluation and possible repercussions in the following years, being paid in cash. The amount of the annual performance bonus will be determined within three months after the approval of EDP's accounts at the Annual General Shareholders Meeting each year, by reference to the previous annual performance period. Key annual performance indicators (and weightings) pursuant to the budget for the year at stake are as follows: • regarding the quantitative component: (i) Growth – Earnings per share recurring (20%), (ii) shareholder remuneration – Total Shareholder return vs Eurostoxx utilities (20%), (iii) Balance sheet solidity – Funds from Operations/Net Debit (10%), (iv) Operational efficiency – Recurring Cash 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 443 Organisation and Corporate Governance OPEX (10%); (v) ESG indicator(s)(20%) including Dow Jones Sustainability Index Results, performance in the employees’ yearly climate study and performance in the customer satisfaction index; the 80% resulting from the weighted sum of these indicators reflects a performance that is common to all members of the EBD; and, • regarding qualitative component: (i) implementation of the Business Plan in the year (25%), (ii) team management (25%), (iii) Teamwork (25%) and (iv) Stakeholder management (25%). This 20% weighting results from an individual qualitative assessment carried out by the Remuneration Committee of the General and Supervisory Board, based on the individual performance of each member of the Executive Board of Directors and, after consultation with the Executive Board of Directors. • Multiannual variable remuneration \- The multiannual variable remuneration will be calculated and will be due within 3 (three) months after the approval of accounts for the last financial year of the three-year period to which it relates and will be paid in EDP Shares. The number of EDP shares to be awarded to each member of the Executive Board of Directors will be the one resulting from the quotient between the value of the remuneration calculated as to be paid in EDP shares after performance evaluation, and the price attribution of EDP shares corresponding to the average price of EDP shares in the last month prior to the General Shareholders' Meeting on 14 April 2021: 4.95 Euros. The multi-annual variable remuneration will be measured according to the fulfilment of long-term financial and non-financial objectives in accordance with the Business Plan approved by EDP, including the Company's sustainability metrics within the scope of ESG (Environment, Social and Governance) policies and objectives. Key multi-annual performance indicators for the three-year term of office (and weightings) against the 2021-2025 Business Plan subject to a prior favourable opinion of the General and Supervisory Board of 24 February 2021, after approval by the Executive Board of Directors: • Regarding the quantitative component: (i) Shareholder remuneration - Total shareholder return vs Eurostoxx utilities (40%); (ii) Growth - Earnings per share recurring cumulative (20%) and (iii) ESG indicators (20%) including increase of share of renewable energy production, emissions reduction and Bloomberg Gender Equality Index Performance. The 80% resulting from the weighted sum of these indicators reflects a performance that is common to all members of the Executive Board of Directors. The remaining 20% result from an individualized qualitative assessment carried out by Remuneration Committee, based on the individual performance of each of the members of the Executive Board of Directors, and after consulting the Executive Board of Directors. • Regarding qualitative component (i) strategy and execution (25%), (ii) employee development (25%), (iii) teamwork and new forms of working and (25%) stakeholders management (25%). For more detailed information please see Part IV – Remuneration Report. General and Supervisory Board In compliance with the provisions of article 440 of the Commercial Companies Code, the remuneration of the members of the General and Supervisory Board is of a fixed nature, taking into account the duties performed. The remuneration of the Chairman of the General and Supervisory Board was fixed considering, namely, the necessary availability for the exercise of the respective functions as well as the significant institutional representation component required. The remuneration of the Chairman of the General and Supervisory Board also includes the costs associated with the use of the vehicle and its driver. The Remuneration Committee elected by the General Meeting defined the remuneration policy for the members of the General and Supervisory Board, having as a guiding principle that it should be simple, transparent, moderate, adapted to the working conditions performed and the Company's economic situation, but, also competitive and equitable, in order to guarantee the purpose of creating value for shareholders and other stakeholders. Based on these criteria and considering the challenges that the Company intends to pursue during the next term of office, the Remuneration Committee elected by the General Meeting decided that the following guidelines should apply: • a distinction must be maintained between the remuneration attributed to the members of the General Supervisory Board and those fixed to the members of the Executive Board of Directors, with the former not being allocated a variable remuneration component or any other remuneration supplement. • the performance with merit and the complexity of the functions performed by the members of each body must be considered, so that the cohesion, stability, and development of the Society are not jeopardized. • regarding the Chairman of the General Supervisory Board, it must be considered that the functions require great availability and include a strong component of institutional representation. He may also chair the 

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 444 Organisation and Corporate Governance Financial Matters Committee/Audit Committee, without additional remuneration. • if the chairmanship of the Financial Matters Committee/Audit Committee is assigned to another member of the General Supervisory Board, other than its Chairman, he/she must have a compatible remuneration, depending on the responsibility of the position and the requirement of availability. • in any case, the Chairman of the General Supervisory Board, or the Chairman of the Financial Matters Committee/Audit Committee, if they are separate persons, may not accumulate any other remuneration in relation to the basis assigned to them. • it is also important to differentiate the performance of other specific functions, within the scope of the General Supervisory Board, namely the participation of members of the General Supervisory Board in other committees, as well as the functions performed in these committees. • finally, it should be considered that, historically, the remuneration of the Chairman of the Board of the General Meeting is similar to the remuneration attributed to the Chairman of a Committee. For this reason, the remuneration of the Chairman of the Board is aligned accordingly, and his inherent membership of the position of Member of the General Supervisory Board is also considered. For more detailed information please see Part IV – Remuneration Report. 70\. How remuneration is structured to allow alignment of the interests of the members of the managing body with the company's long-term interests and how it is based on assessment of performance and discourages excessive risk-taking As set out in the Remuneration report, the Remuneration Policy of the Executive Board of Directors comprises a variable remuneration, with an annual component, and a multi-annual component, with the nature of reward/incentive appropriate to the individual and collective performance of the members of the Executive Board of Directors and the promotion of good conduct, taking into account EDP's short- and long-term, financial and non- financial objectives that are achieved, and the way in which they were achieved (pay for performance). Pursuant to the principles set out in the Remuneration Policy approved at the General Shareholders’ Meeting, the remuneration of the members of the Executive Board of Directors should be aligned with the interests of shareholders, be focused on the creation of long-term value and be compatible with adequate risk management and rigorous, thus contributing to the Company's strategy, to its values and long-term interests and to its sustainability. The right to variable remuneration and its effective payment is conditioned to the non-performance, by the members of the Executive Board of Directors, of any malicious illegal acts known after the evaluation has been carried out, and which cause damage to EDP or jeopardize the sustainability of performance of EDP and are the subject of a claim for compensation to EDP, by shareholders or third parties. EDP’s Executive Board of Directors Members do not enter into contracts, either with the Company or with third parties, the effect of which is to mitigate the risk associated with the variability of the remuneration determined for them by the Company.

The multi-annual variable component is linked to the quantitative and qualitative objectives of EDP's Business Plan, the fulfilment of which will be evaluated at the end of a period of three years, with the respective payment subject to partial deferral. The multi-annual variable remuneration is paid exclusively in shares representing the share capital of EDP.

The number of EDP shares to be awarded to each member of the Executive Board of Directors will be the one resulting from the quotient between the value of the remuneration calculated as to be paid in EDP shares after performance evaluation, and the price attribution of EDP shares corresponding to the average price of EDP shares in the last month prior to the General Shareholders' Meeting on 14 April 2021: EUR. 4.95.

Integrated Annual Report 2022 Corporate Governance Report Information on Ownership Structure, 451 Organisation and Corporate Governance 90\. Transactions that underwent controls in the year Attentive to the current reporting obligations, the Executive Board of Directors, during 2022, submitted to the General and Supervisory Board the information concerning the transactions between related parties. Such information concerned the transactions listed below: • EDP Group, through EDP Clientes, S.A. provided electricity and gas supply services as well as the installation of solar panels to the company Cementos Tutela Veguín in the amount of approximately 90.8 million Euros (Cementos Tutela Veguín is a subsidiary of the Group Masaveu, which, in turn, holds 55.9% of the company Oppidum Capital, SL); • As disclosed to the market on 29 July 2022 and on 23 December 2022, EDP agreed to sell to China International Water & Electric Corporation, company that integrates China Three Gorges group, its 50% stake in Hydro Global Investment Limited, with registered office in Hong Kong, for US$ 68 million; • Additionally, and as disclosed to the market on 15 November 2021 and on 27 June 2022, EDP, through its subsidiary EDP Renováveis, S.A., sold to China Three Gorges a 100% stake in an operational wind portfolio with 181 MW located in Spain, for an Enterprise Value of 328 million Euros. The General and Supervisory Board noted that, with basis on the cases analysed and information provided by the Executive Board of Directors for 2022, there was no evidence that the potential conflict of interests in EDP operations were resolved contrarily to the Company’s interests. At the same time, it is important to highlight Article 17(2) of EDP Articles of Association, that defines a number of matters subject to prior opinion from the General and Supervisory Board. This corporate body has competences to set the parameters for measuring the economic or strategic value of the operations that must be submitted for its opinion, and these were updated by the referred Board on the 13 May 2021\. In this context, in 2022, 8 investment/divestment operations were submitted to the General and Supervisory Board for a prior opinion, with an average amount above 350 million Euros, as well as four financing operations, with the approximate average amount of 1.6 billion Euros Regarding the use of the expedited mechanism for issuing a prior opinion, two operations were submitted to the General and Supervisory Board for financing reasons and seven operations regarding investments or divestments, with an approximate average amount of 345 million Euros. The Kronos Solar Projects GmbH solar generation portfolio was acquired for the amount of 663 million euros, and was the highest value transaction, approved under this mechanism during 2022. Also in this context, during the 2022 financial year, seven operations were submitted to the United States of America Business Affairs Monitoring Committee for a prior opinion, with an average value of 385 million dollars, with the maximum value of which was 600 million dollars. Regarding the issuance of a prior opinion by an expedited mechanism, one operation was submitted to the United States of America Business Affairs Monitoring Committee, with a of 247 million dollars. Regarding transactions analysed by the United States of America Business Affairs Monitoring Committee, none of them had a related party transaction underlying them. 91\. Procedures and criteria applicable to the supervisory body's prior assessment of transactions between the company and holders of qualifying shareholdings or entities related to them in any way The rules in force applicable to the issuance of a prior opinion and to the expedited mechanisms of opinion in urgent cases of the General and Supervisory Board were updated on 13 May 2021, as well as the procedures for communication and provision of clarifications between that corporate body and the Executive Board of Directors. The Articles of Association of EDP also establish that the General and Supervisory Board should set the parameters for measuring the economic or strategic value of the operations that must be submitted to it for an opinion, as well as establish expedited mechanisms for issuing an opinion in urgent cases or when the nature of the matter justifies it and the situations in which exemption from issuing such an opinion is permitted (Article 21 (7)). In fact, the expedited mechanism for issuing an opinion by the General and Supervisory Board can only occur in situations of exceptional urgency or when the nature of the matter justifies it, as set out in the EDP’s Articles of Association and the Internal Regulations of the General and Supervision (Article 15(5)). With reference to prior opinion mechanism, General and Supervisory Board of EDP established a set of demanding rules regarding the conclusion of business between related parties, aimed at preventing situations of conflict of interests. In this context, it is important to highlight the provisions of the Transaction with Related Parties Policy – reviewed in January 2023 - regarding the procedures and criteria applicable to the intervention of the supervisory body for prior assessment of the business purposes to be carried out between the Company and holders of qualifying holdings or entities that are in any relationship with them. In particular, in

The Corporate Centre is organized by Corporate Departments and Business Units, allowing a better optimization and efficiency of the organizational structure. I.2. Diversity in the composition and functioning of the company’s governing bodies Principle I.2.A Companies ensure diversity in the composition of its governing bodies, and the adoption of requirements based on individual merit, in the appointment procedures that are exclusively within the powers of the shareholders. The respect for diversity within the governing bodies and in the appointment, procedures constitute one of the structuring elements of EDP’s corporate purpose. The Internal Regulations of the corporate bodies, corporate entities and Specialized Committees which form part of EDP’s structure set forth several provisions related to reputation, independence, and incompatibilities applicable to the members of those bodies. Regarding the General and Supervisory Board and the Executive Board of Directors, EDP has a specific policy entitled “Policy on Selection of the Members of the General and Supervisory Board and Executive Board of Directors” according to which the integration of several skills, professional experiences, and knowledge, as well as genre and cultural diversity should always be assured, considering the specificities of the Company’s business. Such policy establishes that the election proposal of any candidate to be submitted to the Shareholders’ General Meeting should be duly substantiated in what concerns the candidate’s profile and function to be performed, so as to enable the shareholders to verify the adequacy of the candidate’s profile, knowledge, and curriculum to the functions to be performed. Under the abovementioned policy, some of the general selection criteria are: (i) promotion of equality of rights and opportunities in a context of diversity; (ii) enhancement of diversity, notably regarding age, gender, geographical origin, skills, competences, qualifications, and experience; (iii) promotion of the increase in the number of members of the under-represented gender; and (iv) prevention of potential conflicts of interest. Said selection policy also foresees the competences that the members of the Executive Board of Directors and of the General and Supervisory Board should possess, among which we highlight the following: (i) technical-professional competences suitable for the function; (ii) integrity, ethics and professional and personal values; (iii) sufficient knowledge of the legal, regulatory and statutory rules applicable to its functions and to the Company; (iv) sufficient availability to comply with the respective legal and statutory functions; (v) fulfilment of the independence requirements established by law and in the Articles of Association; (vi) commitment with the provisions set forth in policies, codes and Internal Regulations of the Company; (vii) commitment towards compliance with the best corporate governance practices; (viii) competences and experience in company management, risk management and supervision suitable for the function and (ix) industry knowledge and experience in the sector. In particular, regarding gender diversity, it is convened by compliance with Law 62/2017, of 1 August, related to the balanced representation between men and women in governing and supervisory bodies in public sector entities and listed companies. Furthermore, EDP has a diversity policy according to which it undertakes to (i) promote mutual respect and equal opportunity, (ii) acknowledge the differences as a source of strengthening human potential and valuing diversity in organizing, managing and in the strategy, and (iii) adopt positive discrimination and awareness measures, not only internally but also towards the community in order to have an effective and efficient implementation of the diversity policy. Under the terms of Law no. 62/2017, of 1 Items 11 | Items 15 to 17 and 30 to 33 | Annex I Principle I.2.B Companies should be provided with clear and transparent decision structures and ensure a maximum effectiveness of the functioning of their governing bodies and commissions. Item 21 | Items 27 to 31 Principle I.2.C Companies ensure that the functioning of their bodies and committees is duly recorded, namely in minutes, to allow an understanding not only of the meaning of the decisions taken, but also of their grounds and opinions expressed by their members.

Companies should establish standards and requirements regarding the profile of new members of their governing bodies, which are suitable according to the roles to be carried out. Besides individual attributes (such as competence, independence, integrity, availability, and experience), these profiles should take into consideration general diversity requirements, with particular attention to gender diversity, which may contribute to a better performance of the governing body and to the balance of its composition.

It also enables the enhancement of skills and knowledge through the inclusion of all, promoting a better and more motivating work environment and, consequently, greater levels of productivity and retention of talent. Recommendation I.2.2.

In 2022, and following the entry into force of Law 93/2021 of 20 December, which transposes Directive (EU) 2019/1937, EDP reformulated its whistleblowing channels with a view to structuring an Integrated Whistleblowing Management System.

Also in 2022, EDP approved the Whistleblowing Management Regulation Speak Up that sets forth reception mechanisms and procedures, irregularities communication retention and processing on several matters received by the Company on alleged unethical behaviour that does not comply with the law and internal regulations in force. Under the terms of this Regulation, the communication of irregularities is handled as confidential information by all those who receive information on the reported facts and the anonymity of the whistleblower is assured, if he/she so requests. Further information is available at Speak Up Channel and Whistleblowing Management Regulation. In 2021, the Integrity Policy as well as the remaining procedures and compliance mechanisms associated to this program where the object of training directed at the employees and have been internally disclosed for review in EDP’s internal communication channels.

EDP’s Article of Association expressly set forth that all corporate bodies of the Company should, to the extent of their competences, create the necessary conditions for a harmonious, articulated and informed performance of their duties, with reporting and information sharing mechanisms implemented in accordance with recommendation I.1.1. In addition, the Internal Regulations of the General and Supervisory Board, the Executive Board of Directors and of the specialized committees contain several provisions that set forth the need to report, namely to supervisory bodies, information regarding annual activity plans, resolutions and minutes.

Adopted This recommendation is also complied with considering article 5 of the Internal Regulation of the Executive Board of Directors. Currently, EDP also has an internal instrument that systematizes the operating principles and rules to be observed in the interaction of the Executive Board of Directors with the General and Supervisory Board, developing the legal framework, the Articles of Association and the Internal applicable to such matters. Items 21 to 45 Recommendation I.3.2. Each of the company’s boards and committees should ensure the timely and suitable flow of information, especially regarding the respective calls for meetings and minutes, necessary for the exercise of the competences, determined by law and the bylaws, of each of the remaining boards and committees. Adopted All Internal Regulations set forth reporting and information sharing mechanisms. In particular, it should be highlighted the relevance of the information sharing platform between the General and Supervisory Board and the Executive Board of Directors. Regarding the applicable provisions, one should highlight: \- Articles of Association: Article 22 (1) (L); \- Internal Regulation of the Executive Board of Directors: Articles 5 (1) (e) and 10 (4); \- Internal Regulation of the General and Supervisory Board: Article 5 (c) and (e), and Article 11 (1) (a); Article 14 and Article 17; \- Internal Regulation of the Financial Matters / Audit Committee: Article 5 (1) (f), Article 10 (1) (a) and Article 13; \- Internal Regulation of the Remuneration Committee: Article 5 (1) (d); Article 10 (1) (a) and (2); \- Internal Regulation of the Corporate Governance and Sustainability Committee: Article 5 (e); Article 10 (1) (a), (2), and (3) (c); Articles 12 and 13; Items 21 to 45

I.4. Conflict of interests Principle: The existence of current or potential conflicts of interest, between members of the company’s boards or committees and the company, should be prevented. The non-interference of the conflicted member in the decision process should be guaranteed. Since 17 May 2010, EDP has implemented rules on identification, internal reporting and actions to be carried out should a case of conflict of interests occur. This Regulation is applicable to all EDP Group employees that have a decision-making role on the completion of a transaction with related parties. In 2021, and with the review of internal regulations, the Transaction with Related Parties Policy came into force, aiming to establish general principles of action and reporting in order to identify, prevent, detect and settle situations of conflicts of interest in Related Party Transactions, which was revised in January 2023. In addition, it aims to contribute to the promotion of ethics and integrity in the development of the business of EDP and other companies and/or entities forming part of the EDP Group, ensuring compliance with legislation and the principles and rules laid down. The Internal Regulations of EDP’s bodies and committees set forth provisions by which the members of such bodies and committees should inform the respective body or committee on facts that could constitute or give cause to a conflict between his/hers interests and the corporate interest, the communication of a conflict of interest occurs whenever there are facts that may constitute or give rise to it, and not limited to the deliberative context. All corporate bodies and Specialized Committees’ Internal Regulations set forth a specific provision on the conduct to be adopted by the respective body or committee member in case of an effective or apparent conflict of interests, as well as a duty to provide information or clarifications. The respective articles that specifically set forth this recommendation are the following: \- Internal Regulation GSB: Article 10 \- Internal Regulation EBD: Article 6 \- Internal Regulation FMC/AC: Article 9 \- Internal Regulation RC: Article 9 \- Internal Regulation CGSC: Article 9 \- Internal Regulation BAMC: Article 8 Item 10 | Item 18 | Item 20 | Item 21 | Item 91 Recommendation I.4.1. The members of the managing and supervisory boards and the internal committees are bound, by internal regulation or equivalent, to inform the respective board or committee whenever there are facts that may constitute or give rise to a conflict between their interests and the company’s interest. Adopted Item 10 | Item 18 | Item 20 | Item 21 | Item 91 Recommendation I.4.2. Procedures should be adopted to guarantee that the member in conflict does not interfere in the decision-making process, without prejudice to the duty to provide information and other clarifications that the board, the committee or their respective members may request. Adopted Item 10 | Item 18 | Item 20 | Item 21 | Item 91 I.5. Related party transactions Principle: Due to the potential risks that they may hold, transactions with related parties should be justified by the interest of the company and carried out under market conditions, subject to principles of transparency and adequate supervision. Regarding this matter, in addition to the legal and statutory provisions, there is an internal regulation on conflicts of interest and transactions with related parties, reviewed in January 2023 - Transactions with Related Parties Policy – which is available for consultation at EDP’s website. Under the terms of EDP’s Articles of Association and the applicable law, the Executive Board of Directors is responsible for the management of the Company and for transaction with related parties purposes, are deemed decision-makers: (i) the members of EDP's corporate bodies and its Subsidiaries Companies; (ii) first-line managers of the EDP Corporate Centre reporting directly to the management; (iii) first-line managers of the company controlled by EDP who report directly to the management within the scope of the activity of that company or of a company under its Control;; (iv) EDP employees, regardless of their labour contract, who may individually perform acts in the amount equal to or greater than EUR 100,000, as a result of the respective delegations of powers or in accordance with the limits arising from the respective established legal relationships; (v) whenever the EBD expressly qualifies EDP Group employees as decision-makers, indicating the respective scope of activity. All decision-making persons should therefore report any information deemed relevant over transactions performed or to be performed with related parties, namely with Item 10 | Items 89 to 92 Recommendation I.5.1. The managing body should disclose in the corporate governance report or by other means publicly available the internal procedure for verifying transactions with related parties. Adopted Item 10 | Items 89 to 92 

Integrated Annual Report 2022 Corporate Governance Report Assessment of Corporate Governance 459 PRINCIPLES AND RECOMMENDATIONS ADOPTED NOT ADOPTED NOT APPLICABLE COMMENTS REPORT DESCRIPTION controlled companies or with the own decision-makers. There are also identified in Transaction with Related Parties Policy, transactions of significant relevance, specifying the type and scope of the transactions subject to prior opinion. Furthermore, article 17 (2) of EDP’s Articles of Association sets forth a range of matters subject to favourable prior opinion of the General and Supervisory Board, with the Board retaining power to set the parameters, in terms of economic or strategic value of the transactions, that should be subject to opinion, namely regarding acquisitions and disposals of goods, rights or shareholdings of a significant amount, under the terms of article 21 (7) of EDP’s Articles of Association and article 15 of the General and Supervisory Board Internal Regulation. The General and Supervisory Board is responsible for, under the scope of the annual and interim management EDP report assessment and taking into consideration the activity performed by the Financial Matters Committee/Audit Committee, analyse, and issue an opinion regarding transactions with related parties. In effect, the General and Supervisory Board contains a Specialized Committee, the Financial Matters Committee/Audit Committee, whose attributions include reviewing related party transactions. Its Internal Regulation clarifies that the final decision is up to the General and Supervisory Board, in accordance with article 12 (1) (i). Furthermore, the Corporate Governance and Sustainability Committee is responsible for monitoring and supervising the systems for evaluating and resolving conflicts of interest, namely regarding the Company's relations with shareholders, by analysing the proposed remedies for situations that reported to it by the Committee by the Financial Matters Committee/Audit Committee. EDP also displays a set of rules on the issuance of prior opinion by the General and Supervisory Board, as well as the communication procedures between the General and Supervisory Board and the Executive Board of Directors. In addition, the Executive Board of Directors should, within 20 (twenty) days of the end of each quarter, inform the General and Supervisory Board of all “significant transactions”, being set forth in the respective policy the elements that should be submitted on such communication (see Article 22 (1) (l) of the Articles of Association and article 14 (1) (k) of the General and Supervisory Board Internal Regulation). The General and Supervisory Board intervention in the assessment made to such transaction is always preceded of the analysis and scrutiny of the Executive Board of Directors. Also, under the terms of the Internal Regulation in force regarding this matter, the General and Supervisory Board and, more specifically, the Financial Matters Committee/Audit Committee analyses all transactions between EDP and subsidiaries in the amount equal or superior to: (i) EUR 75M, for subordinated and standard loans; (ii) EUR 75M for purchase, sale, marketing or supply of electricity and natural gas (and connected products and services) and (iii) EUR 5M for all other transactions. Recommendation I.5.2. The managing body should report to the supervisory body the results of the internal procedure for verifying transactions with related parties, including the transactions under analysis, at least every six months. adopted For Transaction with Related Parties Policy purposes, the Executive Board of Directors should inform the General and Supervisory Board, within 20 (twenty) days after the end of each quarter, of all transactions that constitute relevant situations.

Integrated Annual Report 2022 Corporate Governance Report Assessment of Corporate Governance 460 PRINCIPLES AND RECOMMENDATIONS ADOPTED NOT ADOPTED NOT APPLICABLE COMMENTS REPORT DESCRIPTION shareholders in matters of corporate governance is a positive factor for the company’s governance. Principle II.B The company should stimulate the personal participation of shareholders in general meetings, which is a space for communication by the shareholders with the company’s boards and committees and also of reflection about the company itself. Item 5 | Item 6 | Item 7 | Item 10 | Items 12 to 16 | Item 56 Principle II.C The company should implement adequate means for the participation and remote voting by shareholders in meetings. Item 5 | Item 6 | Item 7 | Item 10 | Items 12 to 16 | Item 56 Recommendation II.1. The company should not set an excessively high number of shares to confer voting rights [II.1.(1)], and it should make its choice clear in the corporate governance report every time its choice entails a diversion from the general rule: that each share has a corresponding vote [II.1.(2)]. Adopted [II.1.(1)] EDP establishes in Article 14 (1) and (2) of its Articles of Association that to each share corresponds one vote and that all shareholders with voting rights may participate in the Shareholders’ General Meeting provided that they have such capacity on registration date. [II.1.(2)] \- Not applicable. Item 5 | Item 6 | Item 7 | Item 10 | Items 12 to 16 | Item 56 Recommendation II.2. The company should not adopt mechanisms that make decision making by its shareholders (resolutions) more difficult, specifically, by setting a quorum higher than that established by law. Adopted Article 11 (3) of EDP’s Articles of Association establishes that Shareholders’ General Meeting resolutions are adopted by a majority of voting cast, unless a legal or statutory provision requires a qualified majority. Item 5 | Item 6 | Item 7 | Item 10 | Items 12 to 16 | Item 56 Recommendation II.3. The company should implement adequate means for the participation and remote voting by shareholders in meetings. Adopted While EDP has always favoured maximizing shareholder participation in general meetings, which entails direct interaction with the holders of its share capital, which constitutes a positive factor for the proximity with its shareholding structure, for the efficient functioning of the Company and for the pursuit of its corporate purpose, the COVID-19 pandemic context has inevitably altered that understanding. EDP has held three General Shareholder Meetings in a state of emergency, in 16 April 2020, in 19 January 2021 and in 14 April 2021, and this has required the implementation of procedures to allow the meetings to take place remotely, as per the convening notices available at General Shareholders’ Meetings | edp.com The quorum in the aforementioned Annual and Extraordinary General Shareholders’ Meetings were respectively of 67,3% in April 2020, of 73,9068% in January 2021 and of 74.415 in April 2021. Due to these exceptional circumstances, all voting rights were exercised remotely, either by post or by electronic means, as provided in Article 384(8) and (9) of the Portuguese Companies Code, Article 22 of the Portuguese Securities Code, and in Article 14(6) and (8) of EDP’s Articles of Association. Holding the General Shareholders’ Meeting remotely has allowed all duly registered Shareholders to access the live audio and video feed of the meeting. To that effect, a hyperlink to a digital platform was sent the day prior to the meeting to the registered e-mail address of each shareholder who had communicated its intent to attend. 

Integrated Annual Report 2022 Corporate Governance Report Assessment of Corporate Governance 461 PRINCIPLES AND RECOMMENDATIONS ADOPTED NOT ADOPTED NOT APPLICABLE COMMENTS REPORT DESCRIPTION Besides being able to ask questions in writing, through the platform, about the topics included in the Agenda which warranted clarification during the meeting, shareholders were allowed to submit questions in advance, up to two days prior to the respective General Shareholder Meeting dates. In the Extraordinary General Shareholders’ Meeting held on 19 January 2021 and the Annual General Shareholders’ Meeting held on 14 April 2021, and in order to allow for the complete clarification of the shareholder’s questions before they exercised their voting rights – without prejudice to the timely disclosure of documents supplementing the Agenda and the abovementioned alternative, shareholders were allowed to submit questions within the scope of information rights as foreseen in Article 290 of the Portuguese Companies Code, up to 8 (eight) days before the meeting, so that shareholders have all the questions they had before the exercise of voting rights were fully clarified. At the General Shareholders’ Meeting held on 6 April 2022, EDP implemented a hybrid model, giving shareholders the option to participate in the General Shareholders’ Meeting in person or by telematic means. Recommendation II.4. The company should also implement adequate means for the exercise of remote voting, including by correspondence and electronic means. Adopted EDP’s Articles of Association enable the exercise of voting rights by post (Article 14 (6)), they also, on the other hand, determine the procedure for the exercise of postal vote, including by electronic means, in accordance with requirements that ensure its authenticity (Article 14 (6) to (8). At EDP’s website shareholders may find the necessary drafts for postal and e-mail voting. Due to the abovementioned exceptional circumstances, all voting rights in the General Shareholder Meetings held in April 2020 and January and April 2021 were exercised remotely, either by post or by electronic means, as provided in Article 384(8) and (9) of the Portuguese Companies Code, Article 22 of the Portuguese Securities Code, and in Article 14(6) and (8) of EDP’s Articles of Association. Holding the General Shareholder Meeting remotely has allowed all duly registered Shareholders to access the live audio and video feed of the meeting. EDP has been actively seeking technological solutions that are safe and ensure audio quality, transparency and voting secrecy, which are compatible with the Portuguese legal framework, in order to implement real-time electronic voting. Item 5 | Item 6 | Item 7 | Item 10 | Items 12 to 16 | Item 56 Recommendation II.5. The bylaws, which specify the limitation of the number of votes that can be held or exercised by a sole shareholder, individually or in coordination with other shareholders, should equally provide that, at least every 5 years, the amendment or maintenance of this rule will be subject to a shareholder resolution — without increased quorum in comparison to the legally established — and in that resolution, all votes cast will be counted without observation of the imposed limits. Not adopted Considering the current shareholder structure of the Company, this recommendation does not have any practical applicability. However, over the past few years, the subject of statutory limitation on voting rights has already been discussed by the General Shareholders Meeting of EDP on three occasions, the last of which on 24 April 2019. The shareholders have thus been called on to decide on limiting the number of votes. The continued existence of the limitation has prevailed, and the reflection on the adjustment of the relevant ceiling for counting voting rights has been precisely to progressively increase this level. The shareholding dynamics of the Company has thus proven to be perfectly in tune with the sense advocated in this recommendation, and to be sufficiently apt for pursuing its goals, avoiding rigid formulas for this review set down in the Articles of Association, which has also fostered a particularly intense scrutiny of this clause by shareholders, and does not constitute an impediment to adequate functioning of the market for corporate control. These circumstances confirm that the voting cap does not prevent the relevant shareholders’ involvement in EDP’s corporate governance, again bearing in mind that three resolutions of the General Shareholders’ Meeting have been adopted, from 2011 to 2019, regarding this statutory limitation. In effect, the voting limitation set forth in article 14 of the Articles of Association reflects the express wish of EDP’s shareholders through the General Meeting resolutions, in the defense of the Company’s specific interests: (i) the increase of the limit from 5% to 20% was approved by the shareholders at the General Meeting of 25 August 2011, involving the participation of 72.25% of the share capital and the approval of a majority of 94.16% of the votes cast; (ii) a subsequent increase to the current 25% cap was approved at the General Meeting of 20 February 2012, involving the 

Integrated Annual Report 2022 Corporate Governance Report Assessment of Corporate Governance 462 PRINCIPLES AND RECOMMENDATIONS ADOPTED NOT ADOPTED NOT APPLICABLE COMMENTS REPORT DESCRIPTION participation of 71.51% of the share capital and the approval by a majority of 89.65% of votes cast and (iii) the removal of the voting cap set out in the Articles of Association was rejected by a majority of 56.61% of votes cast, with the participation of 64.29% of the share capital. Recommendation II.6. The company should not adopt mechanisms that imply payments or assumption of fees in the case of the transfer of control or the change in the composition of the managing body, and which are likely to harm the free transferability of shares and a shareholder assessment of the performance of the members of the managing body. Adopted As provided for in EDP’s Corporate Governance Manual, there are no known measures in place that prevent free transmission of shares and free performance assessment of the members of the Executive Board of Directors. Identically, EDP has not entered into any significant agreements that come into force, are amended or terminate in the event of a change in control of the Company following a takeover bid, except for normal market practice in terms of debt issuance. In fact, EDP is usually a party in financing agreements and issuer of bonds that include change of control clauses, which are typical set forth in such agreements and securities and are necessary for the completion of transactions, not considering that its existence is likely to harm the economic interest in the transfer of EDP shares, nor the free assessment by shareholders of the directors' performance. Additionally, with regard to measures adopted that determine payments or the assumption of costs by the company in the event of a change in the composition of the management body, and in addition to the situations referred in the Remuneration Report, there are no contracts in force at EDP that provide for payments in the event of dismissal or termination by agreement of the director's duties, nor any other measures that determine the assumption of liabilities by EDP in the event of a change in the composition of the management body. Items 4 and 5 | Remuneration Report CHAPTER III – NON-EXECUTIVE MANAGEMENT, MONITORING AND SUPERVISION Principle III.A The members of governing bodies who possess non- executive management duties or monitoring and supervisory duties should, in an effective and judicious manner, carry out monitoring duties and incentivize executive management for the full accomplishment of the corporate purpose, and such performance should be complemented by committees for areas that are central to corporate governance. Items 15 to 19 | Item 21 | Item 29 Principle III.B The composition of the supervisory body and the non-executive directors should provide the company with a balanced and suitable diversity of skills, knowledge, and professional experience. The election proposal of any candidate of the General and Supervisory Board and of the Executive Board of Directors to be submitted to the General Shareholder Meeting should be duly substantiated, considering the candidate’s profile and function to be performed so as to enable the verification of the adequacy of the candidate’s profile, knowledge and curriculum. Among the established criteria are (i) the promotion of equality of rights and opportunities in a context of diversity; (ii) the enhancement of diversity, notably in matters of age, gender, geographical origin, skills, competences, qualifications and experience; (iii) the promotion of the increase in the number of members of the under-represented gender; (iv) prevention of potential conflicts of interest. As provided in recommendation I.2.1, a selection policy is in force which sets forth specifically the skills that the members of such bodies should possess. Item 21 | Item 29 | Item 31 | Item 68 Principle III.C The supervisory body should carry out a permanent oversight of the company’s managing body, also in a preventive perspective, following the company’s Items 15 to 19 | Item 21 | Item 29

Recommendation III.1. Without prejudice to the legal powers of the chair of the managing body, if he or she is not independent, the independent directors should appoint a coordinator, from amongst them, namely, to: (i) act, when necessary, as an interlocutor near the chair of the board of directors and other directors, (ii) make sure there are the necessary conditions and means to carry out their functions; and (iii) coordinate the independent directors in the assessment of the performance of the managing body, as established in recommendation V.1.1. Not Applicable This recommendation is not applicable considering the Company’s governance model in force. Recommendation III.2. The number of non-executive members in the managing body [III.2.(1)], as well as the number of members of the supervisory body [III.2.(2)] and the number of the members of the committee for financial matters [III.2.(3)] should be suitable for the size of the company and the complexity of the risks intrinsic to its activity, but sufficient to ensure, with efficiency, the duties which they have been attributed. The formation of such suitability judgment should be included in the corporate governance report. Adopted [III.2(1)] This sub-recommendation is not applicable in light of the governance model in force at the Company. [III.2.(2)] The General and Supervisory Board is composed of a minimum of nine members, but always higher than the number of directors, under Article 21 (1) of the Articles of Association. [III.2.(3)] The Financial Matters Committee / Audit Committee should be composed by at least three independent members according to Article 3 of the Financial Matters Committee / Audit Committee Internal Regulation, which is entirely proportional to the Company’s features. Item 15 | 17 | Item 21 | Item 29 | Recommendation III.3. In any case, the number of non-executive directors should be higher than the number of executive directors. Not applicable This recommendation is not applicable considering the Company’s governance model in force. Recommendation III.4. Each company should include several non-executive directors that corresponds to no less than one third, but always plural, who satisfy the legal requirements of independence. For the purposes of this recommendation, an independent person is one who is not associated with any specific group of interest of the company, nor under any circumstance likely to affect his/her impartiality of analysis or decision, namely due to: i. having carried out functions in any of the company’s bodies for more than twelve years, either on a consecutive or non-consecutive basis; Not applicable This recommendation is not applicable considering the Company’s governance model in force.

Recommendation III.5. The provisions of (i) of recommendation III.4 does not inhibit the qualification of a new director as independent if, between the termination of his/her functions in any of the company’s bodies and the new appointment, a period of 3 years has elapsed (cooling-off period). Not applicable This recommendation is not applicable considering the Company’s governance model in force. Recommendation III.6. The supervisory body, in observance of the powers conferred to it by law, should assess and give its opinion on the strategic lines [III.6.(1)] and the risk policy prior to its final approval by the management body [III.6.(2)]. Adopted EDP’s current governance model foresees the attribution to the General and Supervisory Board of a significant function in this respect. While it does not have managerial attributes, as provided in Article 422(1) of the Portuguese Companies Code, Article 17(2) of EPD’s Articles of Association provides (as does Article 15 of the Internal Regulation of the General and Supervisory Board) that the Company’s strategic plan as well as the performance, by EDP or any of its subsidiaries, of the following transactions are subject to prior favourable opinion of this body: (i) acquisition and sale of assets, rights or shareholdings of significant economic value, (ii) contracting financing operations of significant value, (iii) the opening and closure of establishments, or important parts thereof, and important increases or reductions in activity, (iv) other transactions or operations of significant economic or strategic value, (v) the commencement or termination of strategic partnerships or other forms of lasting cooperation, (vi) plans for divisions, mergers or transformations, and (vii) changes to the EDP’s Articles of Association, including moving the head office and increasing the share capital proposed by the Executive Board of Directors. Also relevant are the specific attributions of the Financial Matters Committee / Audit Committee regarding financial and accounting matters, Item 21 | Item 24 | Item 29 | Items 49 to 55 

Integrated Annual Report 2022 Corporate Governance Report Assessment of Corporate Governance 465 PRINCIPLES AND RECOMMENDATIONS ADOPTED NOT ADOPTED NOT APPLICABLE COMMENTS REPORT DESCRIPTION internal auditing practices and procedures, the functioning of the Internal Control System of Financial Reporting (SCIRF), matters relating to risk management procedures and compliance mechanisms, as well as the work and independence of the Company’s statutory auditors. The Financial Matters Committee/Audit Committee is responsible for monitoring, on a permanent basis, the assessment of internal procedures regarding the effectiveness of the risk management system, internal control and internal audit systems, and must evaluate and comment on the strategic lines and policy of the EDP Group's corporate risk management prior to the respective final approval by the Executive Board of Directors, under the terms of article 12 (2) (i) of the Internal Regulation of the FMC/AUDC. The General and Supervisory Board is also involved in the EDP Group's Business Plan, implicitly ensuring an alignment between management and shareholders with regard to the Group's risk appetite. Key risk indicators are also regularly reported to the General and Supervisory Board, in line with performance metrics and which allow this body to monitor the evolution of the Company's risk profile. Recommendation III.7. Companies should have specialized committees, separately or cumulatively, on matters related to corporate governance [III.7.(1)], appointments [III.7.(2)], and performance assessment [III.7.(3)]. In the event that the remuneration committee provided for in article 399 of the Commercial Companies Code has been created and should this not be prohibited by law, this recommendation may be fulfilled by conferring competence on such committee in the aforementioned matters Adopted [III.7(3)] The Remuneration Committee elected by the General Meeting (CVEN AG) is responsible for submitting a proposal for a remuneration policy for the members of the General and Supervisory Board, the members of the Board of the General Meeting, the ROC and the members of the Environment and Sustainability Board. One of the guiding principles of CVEN AG's activity is based on the definition of a simple, clear, transparent policy in line with EDP's culture, so that the remuneration practice can be based on uniform, consistent, fair, and balanced criteria. In this context, the remuneration policy proposed by CVEN AG aims to ensure levels of homogeneity and stability compatible not only with the necessary cohesion of the governing bodies and bodies, but also and above all with their non-executive nature, not being considered desirable to attribute variable remuneration mandatorily conditional on the performance of the respective members. In this context, it is considered appropriate to defend the - growing - differentiation between the remuneration treatment of directors with executive functions, on the one hand, and that of the remaining members of the other governing bodies, namely supervisory and supervisory bodies, on the other hand. Thus, and in line with the provisions of the applicable legislation, the fixed remuneration safeguards the distance between the exercise of supervisory and/or supervisory functions and the risk inherent to business activity, as well as the fundamental independence within the scope of supervision and/or unbiased and effective supervision. The aforementioned differentiating treatment is even reflected in the IPCG Code itself, namely under the terms of the Chapter V Principle, according to which “Society shall promote the evaluation of the performance of the executive body and its individual members and also of the overall performance of the body”. of administration and of the specialized committees constituted within it.”. In this instance, the performance evaluation of members of corporate bodies other than the members of the Executive Board of Directors, the General and Supervisory Board and the Specialized Committees is performed in a different way, and, for this purpose, solid mechanisms of checks and balances and internal control are sufficient. In this sense, in addition to the shareholder prerogative at the General Shareholders’ Meeting, there are internal mechanisms, of an instrumental nature, to evaluate, at first hand and with in-depth knowledge, the performance of the members of the governing bodies and bodies, there are no benefits to establish a mechanism additional measure to assess the individual performance of each of the members of EDP's corporate and governing bodies. In this sense, the performance evaluation mechanisms are duly safeguarded, namely through the evaluation and self-evaluation process of the General and Supervisory Board, certified by a specialized external entity, including the Chairman of the Board of the General Meeting, of the evaluation process of the Statutory Auditor by the FMC/AUDC, with the Environment and Sustainability Board being a social Item 21 | Item 29 | Remuneration Report | Annual Reporto of the General and Supervisory Board 

Integrated Annual Report 2022 Corporate Governance Report Assessment of Corporate Governance 466 PRINCIPLES AND RECOMMENDATIONS ADOPTED NOT ADOPTED NOT APPLICABLE COMMENTS REPORT DESCRIPTION body with consultative functions and whose the monitoring of its activity is performed by the Executive Board of Directors . Considering that the Remuneration Policy proposed by CVEN AG only proposes to provide for the remuneration - always with a fixed nature - of the aforementioned governing bodies and bodies and the Company having established effective and resilient internal mechanisms of evaluation and control to assess the individual performance of each one of the members, including their contribution to the functioning of the body and the relationship between the various bodies of the Company, this sub-recommendation [III.7(3)] should be considered as equivalent to adoption. CHAPTER IV – EXECUTIVE MANAGEMENT Principle IV.A As a way of increasing the efficiency and the quality of the managing body’s performance and the suitable flow of information in the board, the daily management of the company should be carried out by directors with qualifications, powers and experience suitable for the role. The executive board is responsible for the management of the company, pursuing the company’s objectives and aiming to contribute towards the company’s sustainable development. Item 17 | Item 18 | Item 19 | Item 21 Principle IV.B In determining the number of executive directors, it should be taken into account, besides the costs and the desirable agility in the functioning of the executive board, the size of the company, the complexity of its activity, and its geographical spread. Item 17 | Item 18 | Item 19 | Item 21 Recommendation IV.1. The managing body should approve, by internal regulation or equivalent, the rules regarding the action of the executive directors applicable to their performance of executive functions in entities outside of the group. Adopted The Internal Regulation of the Executive Board of Directors expressly addresses this issue. In particular, Article 6 provides that board members cannot hold executive functions in more than two companies outside of the EDP Group, and the performance of such functions must be subject to prior appraisal by the Executive Board of Directors. Item 17 | Item 18 | Item 19 | Item 21 Recommendation IV.2. The managing body should ensure that the company acts consistently with its objects and does not delegate powers, namely, in what regards: i) the definition of the strategy and main policies of the company [IV.2.(1)]; ii) the organization and coordination of the business structure [IV.2.(2)]; iii) matters that should be considered strategic in virtue of the amounts involved, the risk, or special characteristics [IV.2.(3)]. Not applicable This recommendation is not applicable in light of the Company’s governance model in force.

Integrated Annual Report 2022 Remunerations Report 511 This Remuneration Report aims to provide a comprehensive and integrated description of the remuneration earned by the members of the governing bodies and bodies of EDP – Energias de Portugal, SA (“EDP” or “Company”), including all benefits, regardless of the respective form, attributed or due during the 2022 financial year. As provided for in the EDP Articles of Association until the amendments resulting from the General Meeting held on 14 April 2021, the remuneration of the members of the governing bodies was fixed by a Remuneration Committee appointed by the General Meeting, with the exception of the remuneration of the members of the Board of Directors Executive Board, which were set by a Remuneration Committee appointed by the General and Supervisory Board. These Committees submitted annually to the General Shareholders’ Meeting a declaration on the remuneration policy of the members of the governing bodies, pursuant to the provisions of paragraph 1 of article 2 of Law no. 28/2009, of 19 June. With the entry into force of Law no. 50/2020, of 25 August, which transposed Directive (EU) no. 2017/828 of the European Parliament and of the Council of 17 May 2017, the Remuneration Committee is responsible to submit to the Company's General Shareholders’ Meeting a proposal for a Remuneration Policy for the Members of the Governing Bodies. Following the General Meeting held on 14 April 2021, the proposal for the remuneration policy of the members of the governing bodies submitted by the Remuneration Committee appointed by the General Meeting, the proposed policy remuneration of the members of the Executive Board of Directors, which was submitted by the Remuneration 1 For more information, see: Remuneration Report EDP 2020 e Remuneration Policy Statement submitted to the General Shareholders Meeting from April 16th 2020 Committee appointed by the General and Supervisory Board, the last two respectively by 98.69% and 98.58%. At the General Meeting of April 6, 2022, the individual and consolidated financial statements for 2021, including the sole management report (including chapter on corporate governance and the remuneration report), the individual and consolidated accounts and the annual report and the opinion of the General and Supervisory Board (which includes the annual report of the Financial Matters/Audit Committee) and the legal certification of the individual and consolidated accounts were approved by the majority of the votes cast (98.66% of votes in favour). A. Remuneration policy applicable to members of the Executive Board of Directors approved by the Remuneration Committee appointed by the General and Supervisory Board Procedures for adopting the policy Until the General Shareholders’ Meeting held on 14 April 2021, the definition of the remuneration policy for the members of the management body was defined by the Remuneration Committee appointed by the General and Supervisory Board, which established a fixed component and a variable component. Regarding the variable component, this Committee established the remuneration to be awarded to the directors, seeking to ensure that it reflected the performance of each of the members of the Executive Board of Directors in each year of the mandate (annual variable remuneration), as well as their performance for the entire term of office, by setting a variable component 2 For more information, see: Remuneration Policy approved at the General Shareholders Meeting of April 14th 2021 consistent with maximizing EDP's long-term performance (multi-annual variable remuneration). The remuneration policy was revised annually 1 and, with the same periodicity, was subject to the General Shareholders’ Meeting appreciation. At the General Shareholders’ Meeting held on 14 April 2021 approved the proposed remuneration 2 policy for the members of the Executive Board of Directors, submitted by the Remuneration Committee appointed by the General and Supervisory Board. As stated in the remuneration policy for the members of the Executive Board of Directors prepared by the Remuneration Committee appointed by the General and Supervisory Board, under the terms of Law no. 50/2020, 25 August, and considering the Corporate Governance Code of the Portuguese Institute of Corporate Governance (IPCG) adopted by EDP, the beginning of a mandate with a new Executive Board of Directors, and also the approval of a new business plan and the feedback received from analysts and investors on the remuneration system of the Executive Board of Directors, understood the Remuneration Committee of the General and Supervisory Board it was opportune to review the Remuneration Policy of the Executive Board of Directors, submitting the proposal for the Remuneration Policy of the Executive Board of Directors of EDP resulting from the aforementioned revision to the EDP General Shareholders’ Meeting of 14 April 2021 for approval. The policy review work that gave rise to the proposal presented to the General Shareholders’ Meeting was also based on the conclusions of a study requested by the Remuneration Committee of the General and Supervisory Board and carried out by an independent consultant, as well as on the advice obtained by the aforementioned Committee

In the proposed Executive Board of Directors' Remuneration Policy, the evolution of the remuneration system for directors and other EDP employees, the reduction in the number of members of the Executive Board of Directors, with the functional reorganization of that Board and consequent increase in responsibilities resulting therefrom, in particular for the global lower remuneration level of the Executive Board of Directors, also taking into account the reasonable expectations of its members, elected in January 2021, regarding the remuneration model and its adequacy and competitiveness. The consideration of employment conditions and the remuneration model for EDP's workers and the economic and financial situation in the country and worldwide also contributed to this end. In fact, the consideration of these elements advised that, on that occasion, and without prejudice to the reduction in the number of levels of fixed remuneration of the members of the Executive Board of Directors, as described below, no further review of the fixed component of the remuneration should be carried out. of the members of the Executive Board of Directors, with the impact that such an option has on the other components of the remuneration, although from the point of view of analysing the functions of the current five members of the Executive Board of Directors and the sector benchmark, such a review could prove to be appropriate. EDP, as the apex of a responsible multinational business group (“Group”) has a solid governing culture that ensures the management, monitoring, control, and supervision of the risks that the Group, its shareholders, employees, customers and, in general, all its stakeholders face, including those arising from the remuneration systems it adopts. EDP adopts remuneration practices transversal to the Group, consistent and based on common principles, which comply with the regulations applicable in the jurisdictions where it carries out its activity. EDP's remuneration systems, including those of the Executive Board of Directors, are defined to promote a culture of merit and high performance that ensures that people and teams are recognized, encouraged and rewarded according to their responsibility, availability, loyalty and competence placed at the service of EDP, guaranteeing action in line with the long-term interests of shareholders and its stakeholders and the promotion of sustainable performance by EDP aligned with ESG (Environment, Social and Governance) objectives. The proposal for the Remuneration Policy for the members of the Executive Board of Directors was also aimed at simplification, transparency, and clarity, favouring a complete understanding of the framework of principles and rules that constitute it, which are applied by the Remuneration Committee of the General Board and Supervision. Definition, review, and renewal of the Policy The definition of the remuneration policy of the Executive Board of Directors is submitted for approval by the General Meeting of EDP, at the proposal of the Remuneration Committee of the General and Supervisory Board. Changes to the Internal Regulations of the Remuneration Committee of the General and Supervisory Board include the process of reviewing and applying the Remuneration Policy of the Executive Board of Directors, in accordance with the following principles: • the Remuneration Committee of the General and Supervisory Board meets at least once a semester in order to monitor the situation of EDP in relevant matters for the purposes of determining and fixing the variable remuneration of the Chairman of the Executive Board of Directors and the other Directors and for the analysis of relevant information that may justify the consideration of adjustments to the application of the Remuneration Policy, proceeding as necessary and convenient to the hearing of the Financial Matters Committee/Audit Committee and the Corporate Governance and Sustainability Committee of the General and Supervisory Board, of the Executive Board of Directors or any of EDP’s corporate body in terms of compliance, risk management and Human Resources; • the definition and possible proposals for reviewing the Remuneration Policy are based on the articulation of EDP's long-term objectives, measured according to its strategic plan at any given moment, on the conclusions of comparative remuneration studies with national listed companies and with peers’ foreign sectors and in an articulation of principles with the remuneration plan of other workers and employees of EDP; • on an annual basis, the Remuneration Committee of the General and Supervisory Board will assess the opinions expressed by shareholders and analysts on EDP's Remuneration Policy or on the Remunerations Report; • the Remuneration Committee of the General and Supervisory Board may hire the consultants and external support necessary to carry out studies on comparative remuneration and best corporate 

Integrated Annual Report 2022 Remunerations Report 513 governance practices within the scope of remuneration policies for directors, assessing their independence conditions to the provision of services that may be requested. Without prejudice to (extraordinary) revision proposals, the Remuneration Committee of the General and Supervisory Board should, at least at the end of each term of office, when assessing compliance with the objectives set for the term in question, specifically analyse and decide on a reasoned basis, on the opportunity to propose the revision/update (ordinary) of the Remuneration Policy in any of its components, in order to ensure, at all times and with adequate agility, the fulfilment of the objective of the remuneration policy of retention and attraction of talent. The review of the base remuneration must also imply the weighting, according to benchmark criteria, of the total remuneration model practiced by comparable companies, in order to always ensure that the remuneration model of the members of the Executive Board of Directors of EDP remains balanced, fair, and competitive. Whenever a remuneration policy is proposed for reviewed, all relevant changes introduced will be described and how these changes reflect the votes and opinions expressed by shareholders on the remuneration policy, as well as the remuneration reports issued based on the aforementioned policy. Principles and General Characteristics The Remuneration Policy of the Executive Board of Directors of EDP aims to comply with the applicable legislation, also in terms of its content, under the terms of Article 26-C of the Securities Code, the IPCG Corporate Governance Code adopted by EDP and good international practices, being mutatis mutandis coherent and consistent with the remuneration policy and remuneration practices applied to Group employees. Regardless of the functions performed in companies of the Group, namely at EDP Renováveis, in accordance with the Remuneration policy of the members of the Executive Board of Directors, the members of this Board do not receive any remuneration or benefit from any other company of the Group, being exclusively remunerated through EDP. The remuneration of the members of the Executive Board of Directors must be aligned with the interests of shareholders, be focused on the creation of long-term value and be compatible with adequate and rigorous risk management, thus contributing to the Company's strategy, to its long-term values and interests and for its sustainability. Total remuneration and the remuneration model, in general, must be competitive, aligned with the practices of the international electricity sector and the market, facilitating the attraction and retention of talent, and the commitment to the company's challenges and ambitions. The competitiveness of the remuneration model/system of the Executive Board of Directors must be regularly and periodically assessed, namely through the analysis of the functions performed and benchmark exercises to be carried out with the support of independent entities, which is assumed to be done with a minimum triennial frequency, corresponding to the duration of the term-of-office of the Executive Board of Directors. The Executive Board of Directors' Remuneration Policy ensures a (fixed) base remuneration, the payment of which is not dependent on performance evaluation, which must be fair, competitive, and sufficiently relevant in relation to the total remuneration, in order to allow greater flexibility in the conformation of the variable component of the remuneration. The Remuneration Policy of the Executive Board of Directors comprises a variable remuneration, with an annual component, and a multi-annual component, with the nature of reward/incentive appropriate to the individual and collective performance of the members of the Executive Board of Directors and the promotion of good conduct, considering EDP's short- and long-term, financial, and non- financial objectives that are achieved, and the way in which they were achieved (pay for performance). The annual variable component is linked to financial and non-financial objectives established in accordance with EDP's Annual Budget, measured annually, with an impact on the year and subject to evaluation and consequent repercussion in the following years, being paid in cash. The annual variable remuneration must be determined after the approval of EDP's accounts at the Annual General Meeting each year, by reference to the previous year/period of annual performance. The payment of the annual variable remuneration is partially deferred. The multi-annual variable component is linked to the quantitative and qualitative objectives of EDP's Business Plan, the fulfilment of which will be evaluated at the end of a period of three years, with the respective payment subject to partial deferral. The multi-annual variable remuneration is paid exclusively in shares representing the share capital of EDP (“EDP Shares”). The determination of the variable annual and multi-annual remuneration of the members of the Executive Board of Directors in accordance with the Remuneration Policy is the responsibility of the Remuneration Committee of the General and Supervisory Board. The payment of the variable remuneration is subject to the permanence of the member of the Executive Board of Directors at EDP until the end of the annual or three-year 

Integrated Annual Report 2022 Remunerations Report 514 period of relevant performance, without prejudice to the provisions of the Remuneration Policy. In the event that EDP or members of the Executive Board of Directors are responsible, by shareholders or third parties, for intentional unlawful acts of management, the annual and multiannual variable remuneration of the directors in question may, by decision of the Remuneration Committee of the General and Supervisory Board, be suspended or not awarded, until such claims are determined and, in case they are considered valid, the variable remuneration paid during the period of practice of the facts, overdue, or to be awarded, will be reimbursed, retained or not awarded for compensation for damages caused up to the full amount thereof (malus and clawback clauses). In assessing the annual and multi-annual performance of the members of the Executive Board of Directors and determining the amount of the variable remuneration due to them, the Remuneration Committee of the General and Supervisory Board may take into account exceptional circumstances with which EDP does not comply, caused by decisions of a political or administrative nature beyond the control of the members of the Executive Board of Directors, which have an impact on EDP's performance and level of achievement of objectives, neutralizing their impacts on annual and multi-annual performance metrics, provided that it ensures that, in case of reversal of the decisions of a political or administrative nature in question, by means of an arbitration, judicial or arbitration procedure, the members of the Executive Board of Directors will also not benefit from the effects of such reversal decision. Likewise, the Remuneration Committee of the General and Supervisory Board may consider other exceptional conjunctural and exogenous circumstances that EDP is faced with, which have an impact on the Company's performance and the level of achievement of objectives set for its members. of the Executive Board of Directors, adjusting or justifiably adopting appropriate solutions to neutralize, for the benefit of EDP or the members of the Executive Board of Directors, as the case may be, in whole or in part, the impact of said consequences on annual and multi-annual performance metrics. In addition to some of the benefits provided to EDP employees, which the members of the Executive Board of Directors also benefit from, the members of this Board must also benefit, by virtue of the duties performed and in accordance with market practices and EDP's culture from a set of additional benefits, of a non-financial nature. As with EDP employees and in accordance with the legislation and Article 27(1) of EDP's Articles of Association, the Company must provide directors with a supplementary retirement pension due to old age or disability or, in its place, and in accordance with the practice consistently followed by the company, a retirement savings plan or equivalent instrument, namely a unit linked capitalization insurance. The Financial Matters Committee / Audit Committee and the Corporate Governance and Sustainability Committee of the General and Supervisory Board shall, together with the Remuneration Committee of the General and Supervisory Board and at its request, monitor the adequacy and application of the Policy of Remuneration of the Executive Board of Directors and other documents, namely of a regulatory nature that develop it, with a view to ensuring its compliance with the legislation and internal policies and risk culture of EDP, as well as evaluating its effects on the appetite for risk and how such effects are managed. The Remuneration Committee of the General and Supervisory Board ensures certification, by an independent entity, of the application of performance metrics in accordance with the approved Remuneration Policy. Without prejudice to a proposal for an extraordinary review during the term of office according to benchmark criteria, the Remuneration Policy will be valid for a period of three years (2021-2023) and must be the subject of a proposal for renewal or revision to be submitted to the General Meeting of EDP to be held in 2024. EDP’s Executive Board of Directors Members do not enter into contracts, either with the Company or with third parties, the effect of which is to mitigate the risk associated with the variability of the remuneration determined for them by the Company. Apart from the situations described in this Remuneration Report, there are no contracts in force at EDP that foreseeing payments in the event of dismissal or termination by agreement of the directors' duties. Components of the remuneration of the members of the Executive Board of Directors Fixed Component – Base Remuneration The base remuneration of the members of the Executive Board of Directors must be aligned with the base remuneration practiced by a group of companies comparable with Executive Board of Directors, of the national market (PSI 20 Index) and of the international electricity sector, in terms of size, market capitalization, risk profile, relevance and geographic implantation, also considering, at all times, the complexity of the functions performed, the remuneration conditions of EDP workers and the non-increase of the average remuneration gap of the market between workers and managers. 

Integrated Annual Report 2022 Remunerations Report 515 Considering the reduction in the number of members of the Executive Board of Directors and the organizational / functional review of this structure with the consequent increase in responsibilities resulting therefrom, in particular the lower remuneration level of the Executive Board of Directors, the current Remuneration Policy has eliminated a remuneration level in the EBD, reducing, compared to the previous Remuneration Policy , from three to two, the levels of remuneration of the members of this Board, under the following terms: a.

Integrated Annual Report 2022 Remunerations Report 523 Performance evaluation of the General and Supervisory Board and qualitative assessment of the Executive Board of Directors to be carried out by the Remuneration Committee of the General and Supervisory Board Under the terms of the remuneration policy in force, the remuneration of directors comprises a qualitative component, namely in relation to the annual variable remuneration (weighted by the individual performance evaluation of each of the members of the Executive Board of Directors, representing 20% and taking into account performance during one year) and the multi-annual variable remuneration (weighted by the individual performance evaluation of each of the members of the Executive Board of Directors, representing 20%, and taking into account the performance during the three-year period). For this purpose, the General and Supervisory Board carries out a self-assessment of its activity and performance, as well as of the respective Committees, whose conclusions are presented in the annual activity report of the General and Supervisory Board (Article 12 of the Internal Regulations of the General and Supervisory Board). This corporate body also carries out an independent assessment of the activity and performance of the Executive Board of Directors, conclusions of which are presented to the General Shareholders’ Meeting and annexed to above referred report. EDP, on the initiative of the General and Supervisory Board, voluntarily instituted a formal and objective process to assess both the activity of this body and the activity of the Executive Board of Directors. The experience of recent years has allowed the General and Supervisory Board to introduce some changes to the process with a view to making it more effective and efficient. During 2022, the methodology adopted comprised the following steps: • conduction of the process of collective evaluation of the General and Supervisory Board, its Specialized Committees, and the Executive Board of Directors by an external entity, with a view to carrying out interviews based on individual questionnaires to the members of the supervisory body and to support in completing and validation of the treatment of information supporting the evaluation process; • at the beginning of 2023, each member of the General and Supervisory Board was interviewed by specialized consultants, answering questions of a quantitative and qualitative nature; namely, issues related to the composition, organization and functioning, performance of the General and Supervisory Board's activity and the relationship of this Board with its Specialized Committees and with other EDP governing bodies were analysed; Likewise, issues related to the composition and organization of the Executive Board of Directors, performance of the respective activity and the relationship between the Executive Board of Directors and the General and Supervisory Board were analysed; • assessment reports were produced by the General and Supervisory Board, its Specialized Committees, and the Executive Board of Directors, which were made available for consideration at a meeting of the General and Supervisory Board; • at a meeting, the General and Supervisory Board issued the respective assessment opinions, which are included in this body's annual activity report; • at the General Meeting, in the point concerning the assessment of the Executive Board of Directors, the Chairman of the General and Supervisory Board presents the respective opinion. In January 2023, the General and Supervisory Board also contracted Mercer (Portugal), Lda. to provide services within the scope of certification of the evaluation process of the afore mentioned body, its Specialized Committees, and the Executive Board of Directors. These certifications can be consulted in the 2022 Annual Report of the General and Supervisory Board.

Integrated Annual Report 2022 Remunerations Report 526 Pursuant to Article 402 of the Portuguese Companies Code and Article 27(1) of EDP's Articles of Association, the Company may create old-age or disability retirement pension supplements in favour of the members of the Executive Board of Directors. EDP has not created a supplementary retirement pension fund or plan for directors, instead making annual contributions / or co-contributions with the director to a Retirement Savings Plan (PPR) in a net amount corresponding to 10% of the respective remuneration base. Malus and clawback rules The right to variable remuneration and its effective payment is conditioned to the non-performance, by the members of the Executive Board of Directors, of any malicious illegal acts known after the evaluation has been carried out, and which cause damage to EDP or jeopardize the sustainability of performance of EDP and are the subject of a claim for compensation to EDP, by shareholders or third parties. If the provisions of the previous paragraph are verified, the variable remuneration paid during the period of practice of the facts, overdue, or to be awarded, will be reimbursed, withheld, or not awarded to compensate for the damages caused up to the competition of the full amount thereof. Exceptional payments arising from termination of service and non-compete agreements Following the suspension of duties, during 2020, of Dr. António Luís Guerra Nunes Mexia, Chairman of the Executive Board of Directors for the three-year period 2018- 2020 and João Manuel Manso Neto, Board Member during the same mandate, by court order issued within the scope of the process concerning the termination of Energy Acquisition Contracts and transition to the Contractual Balance Maintenance Costs regime and the extension of the use of the Public Hydric Domain, and the conclusion with EDP, on 20 November 2020, of termination of office and non-compete agreements, it was agreed that EDP would maintain the obligation to pay the aforementioned Directors the monetary amounts due as remuneration in relation to the mandate elapsed between 2018 and 2020, including the respective fixed and variable, annual and pluriannual, whose evaluation is the responsibility of the Remuneration Committee of the General and Supervisory Board, under the terms in force in the respective the remuneration policy statement approved by this Committee and submitted to the appreciation of the General Meeting. In this context, the amounts paid in 2022 are those provided for in the itemized remuneration section of this Remuneration Report. Given that Dr. António Luís Guerra Nunes Mexia had access, as a result and inherent in the performance of their duties, for a period of fourteen years, to knowledge and extensive privileged and particularly sensitive information in terms of competition in relation to the strategy and business of the EDP Group, non-compete pact was also signed with reference to the period after termination of duties. According to the analysis that preceded the conclusion of the termination of functions and non-compete agreements, the interests of the signatory parties were duly safeguarded, with the respective final terms being based on the best market practices. As consideration for the non-compete obligation, EDP undertook to pay to Dr. António Luís Guerra Nunes Mexia, for a period of three years, the amount of 800,000 Euros and the maintenance, during the same period, of the payment of insurance premiums and life insurance, as well as the PPR Life Insurance whose net amount represents 10% of the fixed annual remuneration. The termination and non-compete agreement entered into was subject to approval by the Remuneration Committee of the General and Supervisory Board, under the terms of article 429 of the Commercial Companies Code, article 27 of the EDP Statutes and the article 12, point h) of the Internal Regulations of the Remuneration Committee of the General and Supervisory Board at a meeting held on 13 November 2020, and the General and Supervisory Board, at the meeting held on 17 November 2020, expressed its agreement to the respective conclusion and conferred powers to two members of the Remuneration Committee of the General and Supervisory Board to represent the Company in the signature of the referred agreement. In this context, in 2022, 400,000 Euros were paid to Dr. António Mexia as consideration for the non-compete obligation, in January and July, totalling 800,000 Euros, as well as the aggregate amount of 145.896,72 Euros relating to insurance premiums health and life insurance and PPR Life Insurance. In May 2022, the amount of 73.375,83 Euros was also refunded relating to the Personal Income Tax withheld with reference to the year 2021. B. Remuneration policy applicable to members of the Governing Bodies approved by the Remuneration Committee elected by the General Meeting The Remuneration Committee elected by the General Meeting takes into account, for the purposes of the proposed remuneration policy for the members of the General and Supervisory Board, the Board of the General Meeting and the Statutory Auditor, namely, their fixed nature, as well as the mandatory rules on their determination, in particular the provisions of number 2 of article 440 of the Commercial Companies Code, which explains the criteria for determining the remuneration of the General and Supervisory Board, in article 374-A of the Commercial Companies Code, pursuant 

Integrated Annual Report 2022 Remunerations Report 527 to Law no. 50/2020, of 25 August, on the remuneration of members of the Board of the General Meeting and in article 60 of Decree-Law no. 224/2008, of 20 November, on the remuneration of the Statutory Auditor. It is therefore incumbent upon the Remuneration Committee elected at the General Meeting to set the remuneration of the members of the following governing bodies: Board of the General Meeting, Chairman and members of the General and Supervisory Board, Statutory Auditor and the Environment and Sustainability Board. The Financial Matters Committee/Audit Committee is treated together with the other Specialized Committees of the General and Supervisory Board. Considering the competence of the Remuneration Committee elected at the General Meeting, its attributions aim to define fixed remuneration, so the legal determinations and others relating to variable remuneration, with their various dimensions, are not applicable here, without prejudice to the necessary alignment, underlying the principles that shape remuneration policies, anchored, namely in the EDP Business Plan for the period 2021-2025. Procedures for adopting the policy In the definition of the Remuneration Policy, proposals are made to ensure that remuneration is adequate, contribute to the business strategy and sustainability of EDP and reflect the risk profile and the long-term objectives and interests of EDP, showing still complying with legal norms, principles, and relevant national and international recommendations. The Remuneration Committee elected by the General Shareholders’ Meeting is also attentive to market references, following benchmark studies carried out in due course. Also in defining this policy, the Remuneration Committee elected by the General Meeting maintains interactions both with members of the relevant governing bodies and with the Company's stakeholders. As is the case of the Executive Board of Directors, the General and Supervisory Board and its Specialized Committees, the Remuneration Committee elected by the General Shareholders’ Meeting develops mechanisms for the prevention and management of conflicts of interest, under the terms set out in article 10 of the EDP Statutes, observing the following essential rules: i. When a member of the Remuneration Committee is in a situation of actual or apparent conflict of interest in a decision to be taken by this body, he must previously inform the Committee of the facts that may constitute or give rise to a conflict between his interests and the Social. ii. In the situation referred to in the previous number, the member of the Remuneration Committee must abstain from participating and voting at the meeting in which the topic is discussed and voted on, without prejudice to the duty to provide information and clarifications that the Committee or the respective members ask you. It should also be noted that, under the statutory terms, the Remuneration Committee elected by the General Meeting is composed of a majority of independent members. General Definition and Characterization When defining the remuneration policy presented by the Remuneration Committee and approved at the General Meeting, held on 14 April 2021, the following factors were considered: i. There is a renewal of the governing bodies with some depth, with the decrease in the number of members of the General Supervisory Board being highlighted; ii. Experience has shown that the functions are increasingly demanding and complex, which requires greater availability of this body, and it should be noted that, in 2020, instead of the eleven annual meetings that were usually held, there were nineteen; iii. The remuneration of the governing bodies, with the exception of the remuneration of the Chairman of the General Supervisory Board, has not changed since 2009, and in that year there was a reduction in relation to the 2006/2008 term of office; iv. Remuneration must also consider market comparables and be sufficiently attractive and adjusted to the responsibilities of the functions; v. The current remuneration of the members of the General Supervisory Board is, for the reasons mentioned above, well below market comparables, namely in the sector in which EDP operates. The proposed Remuneration Policy for the Members of the Governing Bodies aims to comply with the provisions of Law no. 50/2020, 25 August, and incorporate the corporate governance guidelines set out in the IPCG Corporate Governance Code adopted by the Company, framing within the guidelines that have been defined by the Company's reference shareholders, which are formulated in accordance with the aforementioned applicable rules and recommendations and with the best practices existing in the sector. It should be noted, as already mentioned, that the proposal for the Remuneration Policy for the Members of the Governing Bodies has a necessarily limited and reduced scope, since the definition of the remuneration policy for the members of the Executive Board of Directors is in charge of the Remuneration of the General and Supervisory Board. 

Integrated Annual Report 2022 Remunerations Report 528 Therefore, the scope of the proposed Remuneration Policy does not include any variable remuneration to directors, remuneration based on shares or any other remuneration complement, a matter that is the responsibility of the Remuneration Committee of the General and Supervisory Board. For this reason, several legal provisions deriving from Law no. 50/2020, 25 August, concerning the referred matters, notably, those set forth in Article 26-C (3) (4) of the Portuguese Securities Code. Principles underlying the remuneration policy of the members of the Governing Bodies (excluding that of the Executive Board of Directors) The Remuneration Committee elected by the General Shareholders’ Meeting defined the remuneration policy for the members of the General and Supervisory Board, having as a guiding principle that it should be simple, transparent, moderate, adapted to the working conditions performed and the Company's economic situation, but, also competitive and equitable, in order to guarantee the purpose of creating value for shareholders and other stakeholders. The Remuneration Committee elected by the General Shareholders’ Meeting based its decisions on remuneration policy on the following main guiding principles: i. Definition of a simple, clear, understandable, transparent policy in line with EDP's culture, so that the remuneration practice can be based on uniform, consistent, fair, and balanced criteria. ii. Definition of a policy consistent with effective risk management and control, to avoid excessive exposure to risk and conflicts of interest and seeking consistency with the Company's long-term objectives and values. iii. Evaluation and encouragement of a judicious action in which merit must be duly rewarded, ensuring levels of homogeneity compatible with the necessary cohesion of the General Supervisory Board, while also considering the economic and financial situation of the company and the country, even though EDP operates on a global scale. iv. Alignment of the remuneration of the various members of the governing bodies by companies with the highest market capitalization and European counterparts, naturally adapted to the Portuguese market. v. The most recent recommendations issued by the European Union and the Securities Market Commission. vi. Alignment of remuneration with the specific responsibilities inherent to the position in question. vii. Alignment of remuneration with the time required to spend in each position. viii. Simplification of the remuneration policy. Structure of the remuneration policy for the members of the Governing Bodies (excluding that of the Executive Board of Directors) Based on these criteria and considering the challenges that the Company intends to pursue during the term of office 2021-2023, the Remuneration Committee elected by the General Meeting decided that the following guidelines should apply i. A distinction must be maintained between the remuneration attributed to the members of the General Supervisory Board and those fixed to the members of the Executive Board of Directors, with the former not being allocated a variable remuneration component or any other remuneration supplement. ii. The performance with merit and the complexity of the functions performed by the members of each body must be considered, so that the cohesion, stability, and development of the Society are not jeopardized. iii. Regarding the Chairman of the General Supervisory Board, it must be considered that the functions require great availability and include a strong component of institutional representation. He may also chair the Financial Matters Committee/Audit Committee, without additional remuneration. iv. If the chairmanship of the Financial Matters Committee/ Audit Committee is assigned to another member of the General Supervisory Board, other than its Chairman, he/she must have a compatible remuneration, depending on the responsibility of the position and the requirement of availability. v. In any case, the Chairman of the General Supervisory Board, or the Chairman of the Financial Matters Committee/Audit Committee, if they are separate persons, may not accumulate any other remuneration in relation to the basis assigned to them. vi. It is also important to differentiate the performance of other specific functions, within the scope of the General Supervisory Board, namely the participation of members vii. of the General Supervisory Board in other committees, as well as the functions performed in these committees. viii. Finally, it should be considered that, historically, the remuneration of the Chairman of the Board of the General Meeting is similar to the remuneration attributed to the Chairman of a Committee. For this reason, the remuneration of the Chairman of the Board is aligned 

Integrated Annual Report 2022 Remunerations Report 529 ix. accordingly, and his inherent membership of the position of Member of the General Supervisory Board is also considered. C. Specifics applicable to the remuneration of the members of the General and Supervisory Board In compliance with the provisions of article 440 of the Commercial Companies Code, the remuneration of the members of the General and Supervisory Board is of a fixed nature, considering the duties performed. The remuneration policy currently in force was approved at the General Shareholders’ Meeting held on 14 April 2021. The remuneration of the Chairman of the General and Supervisory Board was set considering, namely, the necessary availability for the performance of his duties as well as the important component of institutional representation required. The remuneration of the Chairman of the General and Supervisory Board also includes the costs associated with the use of the vehicle and its driver. Remuneration limits Accordingly, and considering the aforementioned, the Remuneration Committee elected by the General Shareholders’ Meeting submitted to the shareholders the proposal for the gross remuneration of the members of the governing bodies identified below, for the financial year that began on 14 April 2021 and until the term of office, under the terms that follow: GENERAL AND SUPERVISORY BOARD ANNUAL REMUNERATION CHAIRMAN OF THE GENERAL AND SUPERVISORY BOARD: EUR. 515,000.00 Member of the General and Supervisory Board: EUR. 70,000.00 Financial matters committee / Audit committee: the following values add to the base remuneration ANNUAL REMUNERATION PRESIDENT: \+ EUR. 73,000.00 (*) (TOTAL DE EUR. 143,000.00) Member: \+ EUR. 25,000.00 (*) Applicable in this term of office, since the function is not performed by the Chairman of the General Supervisory Board.

Integrated Annual Report 2022 Annexes Annex 2 - Reporting principles 539 Annex 2 - Reporting principles EDP has reported in accordance with the GRI Standards for the period from January 1st, 2022 to December 31st, 2022. GRI Standards reporting principles Reporting quality Balance The content of the Report considers both the most positive facts of the year and those less positive when materially relevant. Comparability The information reported covers a four-year time series in the material topics indicators relevant to the EDP group's business (Chapter 2.2. Materiality) and enables a comparative analysis of the company's performance. Transparency An online glossary is provided in Annex 7 – Glossary. helping to understand some of the technical terms used. In addition to the publications in pdf, a web version is also available, facilitating navigation through the different contents. Accuracy The scope of the Report is explained, as well as the consolidation criteria. All exceptions and changes to criteria are duly identified and highlighted. The definitions and descriptions of the calculation methodologies of the main indicators employed are available online, in the glossary. Timeliness The Report has an annual frequency and covers the calendar year 2022. Reliability The internal process verification is described in this page, under ‘Internal and external assurance’. External verification is an additional guarantee of the reliability of the content, regarding the indicators included in GRI Table. Content principles Sustainability context Within the framework of the defined strategy, EDP fosters a corporate culture of permanent demand for excellence in sustainability, based on its nine principles of sustainability (additional information at www.edp.com). The group's sustainability performance is globally reported based on the consolidation criteria defined and described in the next point. Regarding the subsidiary companies, the group defines a clear strategy for continuous improvement of its performance, supported by the internal process of identifying the year's material issues and emerging trends in the sector, always considering the local conditions in which it operates. Regarding the jointly controlled companies, the group positively influences its performance and highlights the major initiatives of the year throughout the Report, when materially relevant. In the supply chain, the approach is management, and the material issues are published. In this context, the group advocates a relationship supported in trust, collaboration and shared value creation (Supplier Management). Finally, on the customer side, EDP has a growth strategy supported by an increasingly clean supply, contributing to higher energy efficiency through decarbonisation solutions (Decarbonising the world). Consolidation criteria The consolidation criteria of non-financial information are as follows: • in the subsidiary companies where the group exercises control, the performance of companies is reported at 100% • in jointly controlled companies and where the group exercises significant influence, the operational, environmental and social information is published, given its relevance to the group. 

Integrated Annual Report 2022 Annexes Annex 2 - Reporting principles 540 A list with the companies and the respective consolidation method is available in Part II – Financial statements. Included in this list is the company Iberenergia, S.A.U. in which the group has a 100% holding and which is consolidated by the full consolidation method. This company owns 15.5% of Trillo Nuclear Power Plant and as EDP is a minority shareholder it does not exercise operational control or have the power to make financial decisions, through the limited percentage it owns of this power plant Given this, EDP does not report operational, environmental and company information regarding this plant in its Integrated Annual Report. However, information on its performance can be consulted at www.cnat.es. Materiality In terms of sustainability management and reporting on its performance, the EDP Group periodically identifies the themes and trends that in the short, medium and long term are capable of influencing value creation for the company. The Material Issues add both financial and non-financial dimensions, namely those of the economic, environmental and social dimensions that may influence, or be influenced by, different EDP stakeholders. The materiality analysis assesses and prioritises the relevance of an issue for EDP and its respective stakeholders, periodically reviewing their expectations in order to support the organisation's decision-making and strategy development process. More detail on the EDP group's internal methodology for determining Materiality, as well as the list of topics analysed in 2020, is available in the EDP group's 2020 Materiality Process Report at www.edp.com. Verification according to AA1000 (2018) Material topics (Chapter 2.2 Materiality) are identified within the framework defined by AA1000 AP (2018), ensuring the identification of critical stakeholders; integrating their expectations into the corporate and operational strategy and seeking to respond appropriately to their expectations. As in previous years, EDP was subject to verification of compliance with AA1000 AP (2018) in 2022 by the auditors, PwC, specifically in the principles of inclusion, materiality, response and impact. Inclusion of stakeholders The principle of inclusion envisages that stakeholders are consulted, that their expectations and concerns are known and are incorporated into the decision-making process. Periodically, interaction initiatives are promoted with different segments of the company's stakeholders, while there are also dedicated communication channels devoted to specific segments. Response and Integrity EDP undertook commitments and delineated Action plans for material themes, replying strategically to the main stakeholders' expectations. The Objectives and Goals are listed in Chapter 2.4. Strategic priorities, and in Chapter 2.2. Materiality is the group's materiality matrix for 2022, whose themes are developed throughout the document. Internal and external assurance The overall coordination of the process of preparing the EDP Sustainability Report is the responsibility of the Sustainability Department. The contents are subsequently viewed and approved by the Executive Board of Directors. The external verification of sustainability content, carried out by PricewaterhouseCoopers & Associados - Sociedade de Revisores Oficiais de Contas, Lda. has the external verification level "Limited" for a set of indicators according to the GRI Table. Except for the emission and energy consumption indicators which are appropriately flagged with “Reasonable assurance".

Simultaneously, the following table identifies the available information that responds to the ten principles of the Global Compact, demonstrating EDP's commitment to this initiative. 

Integrated Annual Report 2022 Annexes Annex 3 - Proposal for the appropriation of profits 542 Annex 3 - Proposal for the appropriation of profits In accordance with Article 30 (1) of EDP’s Articles of Association, the Executive Board of Directors hereby proposes for approval by the Shareholders that: 1\. The 2022 financial year results, in the total amount of € 848,564,984.40, have the following allocation: • Endowment to EDP Foundation * → € 6,200,000.00 • Retained Earnings → € 842,364,984.40 2\. Dividends to be paid in the amount of €0.190 per share, in the total amount of €753.479.392,28. * The proposed endowment amount remains unchanged from 2019. The total amount of € 753,479,392.28 in dividends to be paid from distributable assets, corresponding to €0.190 per share, considers the total number of shares representing EDP’s share capital, nevertheless, under applicable law, no payment of dividends shall take place regarding own shares held by EDP as of the date that dividends are made available for payment, and such amount is added to the amount of retained earnings. Additionally, EDP is studying the possibility of carrying out an accelerated book building under the authorization of article 4, paragraph 4 of the Bylaws. If, as a result of this accelerated book building, the share capital is increased, the proposal for the distribution of results to be presented to the EDP General Assembly will be revised accordingly, in particular: i. allocating the necessary amount to the legal reserve; and ii. maintaining the dividend of €0.190 per share.

Integrated Annual Report 2022 Annexes Annex 5 - Tax transparency 544 Annex 5 - Tax transparency The fiscal footprint of the group EDP is a utility present in 29 countries, the value chain of which includes the activities of production, transportation and distribution and marketing of energy. These activities involve various types of taxes, levies and financial contributions which, when considered in a global manner, determine the level of taxation to which the EDP group is subject. Of all the phases in the EDP value chain, its energy production activity is the one that contributes most significantly to the payment of taxes and other contributions. Tax strategy mission The EDP group´s tax strategy rests on five fundamental pillars: 1\. The EDP group considers that it has an ethical and civic duty to contribute to the financing of the general functions of the states where it is present by paying taxes, levies and other contributions due, contributing to the well-being of citizens and to the development of the group's local businesses. In this context, it carries out its fiscal function with the utmost rigour and professionalism in line with the Fiscal Mission of the EDP group, in accordance with the following principles: • it implements the options which are most appropriate to the business and shareholders in faithful compliance with the spirit and letter of the Law • it pays the taxes that are due in all the geographical areas where it carries out its activity • it adopts the principle of full competition in intra-group transactions, in the context of applicable international rules, guidelines and best practice on transfer pricing in the light of Organisation for Economic Cooperation and Development (OECD) guidelines, implementing across the board an internal transfer pricing policy based on three main principles: i. all intra-group transactions of a commercial or financial nature have pre- defined and aligned pricing with respect to their terms and conditions, in line with what would normally be practised between independent entities in comparable transactions ii. the determination of the transfer price is based on the economic rationale underlying intra-group transaction and cannot, in accordance with the internal rules of the EDP group, constitute a planning tool iii. intra-group transactions are documented in accordance with the transfer pricing legislation in force in each geographical region. Transfer pricing tax dossiers are usually drawn up in which intra-group transactions are identified and their pricing is validated on the basis of economic analyses prepared by an independent body. • it adopts tax practices based on principles of economic appropriacy and commonly accepted business practices • it discloses true and complete information concerning the relevant transactions • it seeks to defend its legitimate interests by administrative means and, where appropriate, judicially, when the payment of any taxes, contributions and levies reasonably raises doubts of legality. 2\. The EDP group reconciles responsible compliance with its tax obligations with the commitment to create value for its shareholders, advocating efficient management of its tax burden through the use of legally available tax benefits and incentives in each jurisdiction and which are appropriate to the business carried out. 3\. The EDP group is committed to maintaining a relationship with the Tax Authorities of the countries where it operates based on principles of trust, goodwill, transparency, cooperation and reciprocity, the aim being to facilitate the implementation of tax law and minimize litigation. However, whenever adjustments promoted by the Tax Authorities, in particular in transfer pricing, result in double taxation of income within the group because different geographical regions are involved, EDP may consider it appropriate to challenge this situation by using the legal mechanisms provided for this purpose (Conventions to Avoid Double Taxation/Friendly Procedure/Tax Arbitration). 4\. The EDP group applies responsible fiscal policies, striving to maintain a low-risk tax profile that allows it to avoid conduct that could generate significant tax risks. To this end, it has put in place an across-the-board risk management policy with the objective of identifying, quantifying, managing, monitoring and minimizing, among other things, fiscal risks, in close liaison with the highest levels of control and decision (Executive Board of Directors and General and Supervisory Board). In this implementation, the General Supervisory Board appointed a Committee on Financial Matters/Audit Committee, which, among others, has the function of tracking and monitoring the group's policy and fiscal activity. 

Integrated Annual Report 2022 Annexes Annex 5 - Tax transparency 545 5\. The EDP group regards transparency as a basic principle for its fiscal function, particularly through: • not using opaque structures or operations in jurisdictions for reasons that are not strictly connected to the economic activity carried out within them. The EDP group does not have subsidiaries in territories considered to be uncooperative under Portuguese legislation and/or OECD guidelines • the mission and Fiscal Policy, followed right across the EDP group, was approved by the group's Executive Board of Directors, is available online and is mentioned in the EDP group’s Report and Accounts. Global contribution of the EDP group In 2022, the EDP group's overall tax contribution to the public revenue of the various countries where it is present amounted to around 3 billion euros, of which 891 million euros corresponded to taxes and contributions borne (paid) by the EDP group and 2.1 billion euros to contributions to the State on behalf of other economic actors, as seen in the following charts (side column and next page). Regarding the taxes borne by the EDP group, Portugal is the country with the highest level of taxation, accounting for 40% of total taxes borne by the EDP group. Considering the set of taxes that are the burden of the E DP group, the most relevant tranche (31%) concerns specific taxation on the energy sector (including the windfall tax paid in Romania and Italy and the Extraordinary Contribution to the Energy Sector in Portugal - ECES), followed by income tax (24%) and, finally, social security contributions borne by companies (17%).

Integrated Annual Report 2022 Annexes Annex 5 - Tax transparency 546 TAXES COLLECTED BY THE EDP GROUP AND DELIVERED TO THE STATES (BURDEN OF OUR AGENTS), BY GEOGRAPHICAL AREA TAXES COLLECTED BY THE EDP GROUP AND DELIVERED TO THE STATES (BURDEN OF OUR AGENTS), BY TYPE OF CONTRIBUTION As regards income taxes, in the main countries in which it operates, the EDP group is subject to nominal rates of taxation varying between 16% in Romania and 31.5% in Portugal, adding municipal and state surtaxes to the nominal rate in the case of companies located in Portugal. In Portugal, taxes borne (paid) in 2022 amounted to 352 million euros, essentially underlining the burden of specific taxation for the energy sector, of which 52 million euros refers to the ECES, and 74 million euros of social tariff. To these amounts should be added 77 million euros of social security contributions payable by the companies and 92 million euros relating to other taxes and levies. With regard to taxes collected by the EDP group and delivered to the states where it carries out its activity (third-party costs), this value rose to 2.1 billion euros in 2022, mostly associated with the collection of excise taxes (e.g.: VAT). Specific taxation for the energy sector Specific taxation on the energy sector is a significant burden on the EDP group, especially in Portugal, which in 2022 represents about 48% of the total amount paid by the entire EDP group in the field of taxes associated with the energy sector. In view of the high impact that the energy sector has on communities (populations and environment), especially the electricity sector, and its weighting in economies, several countries have implemented specific taxation mechanisms in this regard. This taxation is not generally related to the result of the economic activity carried out and is liable to influence the decisions of economic agents in the development of their businesses and in financing, investment and divestment decisions. In fact, while income taxes are levied on taxable income, other taxes, levies and contributions of significant impact relate, for example, to the quantity of energy produced, the use of natural resources, the possession of certain assets associated with the generation and distribution of electricity, waste produced or the use of fossil fuels, and are therefore not related to the economic performance of the business as reflected in its accounting results, thus capturing part of the share value. 39% 34% 24% 3% Portugal Spain Brazil Other (26 countries) €2.1 billion in 2022 40% 3% 34% 13% 6% 2% 2% Consumption Tax Social security contributions payable by workers Income tax withheld at Source Concession rents – distribution activity Audiovisual tax Specific taxation on the energy sector Other €2.1 billion in 2022 

Integrated Annual Report 2022 Annexes Annex 5 - Tax transparency 547 Specific taxation for the energy sector in 2022 In the context of energy emergency and with a view to tackling high energy prices, Council Regulation (EU) 2022/1854 of 6 October 2022 (Regulation) came into force, which provided for, among other things, the introduction of price cap mechanisms for market revenues obtained by electricity producers from, essentially, renewable energy, and a temporary solidarity contribution applicable exclusively to companies active in the crude oil, natural gas, coal and refining sectors. Although the rules contained in this Regulation are aimed at creating standardising measures in the European Union in response to rising energy prices, certain countries where the EDP group is present have introduced unilateral measures, giving rise to the payment of windfall taxes in Romania and Italy, amounting to approximately 101 million euros and 9.5 million euros respectively. Nevertheless, based on the set of countries where the EDP group operates, Portugal continues to be the one with the highest level of energy taxation, both in the number of taxes and in amounts collected, having represented, in 2022, a charge of 176 million euros, as presented here: SPECIFIC TAXES AND CONTRIBUTIONS ON THE ENERGY SECTOR BORNE (PAID) BY THE EDP GROUP, IN PORTUGAL • the social tariff consists of a discount on the electricity bill allocated to economically vulnerable consumers, the number of which has been extended over time, and which is fully financed by ordinary electricity producers. In 2022, the amount borne by the EDP group in this respect amounted to approximately 74 million euros • in 2022, EDP group paid 51.5 million euros by way of ECES. This tax is on the net assets of the production, transport, distribution and marketing of electricity • the mechanism to restore competitive balance between electricity producers operating on Portuguese territory and electricity producers operating in Spain (known as clawback) was created following the introduction of the Impuesto Sobre el Valor de la Producción de la Energía Eléctrica in Spain. The latter was suspended in Spain during 2022, and Portuguese legislature also provided for the suspension of clawback for the same period. However, the chart shows an amount paid of approximately 36 million euros, which corresponds to payments for the years 2019 and 2020. 29% 4% 20% 3% 42% 2% CESE Wind Energy – Rents Paid to Municipalities Clawback Rents of Energy Power Plants Social Tariff – Electricity Other €176 million in 2022 

Integrated Annual Report 2022 Annexes Annex 5 - Tax transparency 548 TAXATION IN THE VALUE CHAIN Disclosure of fiscal information On a quarterly basis, the EDP group describes in its Reports and Accounts the main characteristics of the tax systems applicable in the countries where it operates, such as nominal rates for tax on income, the legal framework for tax losses/benefits and the most relevant legislative changes. In addition, this publicly disclosed information includes an analysis of the reconciliation between the nominal rate and the effective rate of tax on income applicable to the EDP group, in a consolidated way. Through this analysis, the EDP group explains the weighting of the tax on income recorded in the income statement, which includes, overall, the impact of current tax and the effect of existing temporary differences (deferred taxes). To the extent that the international accounting regulation (IFRS) under which the EDP group prepares and discloses its financial statements does not necessarily advocate alignment between the accounting of income tax expenditure or income and the corresponding cash inflow or outflow effect, it should be stressed that the information contained in the report and accounts does not necessarily represent the tax paid or received by the EDP group, in the period to which it relates. Rather, in this Report, taxes paid and received by the EDP group are disclosed on an annual basis, including a set of fiscal information and metrics. In addition, it should be noted that the EDP group, as a multinational group, fully complies with the annual communication and reporting obligations arising from the implementation of the provisions of Action 13 of the Base Erosion and Profit Shifting project (known as Country-by- Country Reporting), which is part of a plan to strengthen transparency for tax administrations adopted by the OECD and G20 countries. This obligation is fulfilled in Portugal by the parent company, in accordance with the established legal deadlines (corresponding to the last reporting period for 2021). Also, within the Framework of the OECD and its Pillar 2 project - which aims to ensure a minimum overall effective taxation of 15% in each geographical region where the multinational company has a presence - EU Directive 2022/2523 was published on 14 December, which came into force the day following its publication in the Official Journal of the EU and is due to be transposed by Member States by 31 December 2023. Taking into account the preliminary analysis carried out on it and the magnitude of EDP group´s consolidated income, it is expected that it will be subject to this tax regulation. However, since its implementation is dependent on the terms under which it is transposed by the various Member States it is not yet possible to anticipate the impact of this regulation on the EDP group. Financial risk management The fiscal risk management and control process begins with the identification and cataloguing of the risks to which the EDP group is subject. In this sense, the EDP group continuously monitors fiscal risks and uncertainties, conducting regular exercises to identify and quantitatively assess its main fiscal risks, and closely monitoring the development of possible external events with potential material impact. The group identifies the risks to which it is exposed based on the following classification: 

Integrated Annual Report 2022 Annexes Annex 5 - Tax transparency 549 • compliance risk, associated with potential full and timely failure to comply with tax obligations • technical analysis risk that leads to potentially less appropriate fiscal decision-making, especially in contexts of uncertainty concerning its fiscal handling • internal and external communication risk, associated with the risk of deficient communication between the teams that make up the tax areas and internal (e.g., business units) or external entities (e.g.: Tax Authorities) • reputational risk, related to distortions in stakeholders’ interpretation of the financial and tax information disclosed. Contingency, in close cooperation with the relevant business units, corporate legal services and external lawyers and consultants, with a six-monthly report of their development presented to the General and Supervisory Board of the EDP group. In addition, the EDP group's Executive Board of Directors is involved in the decision-making process of the most important operations, and fiscal impact, if any, must be analysed, recorded and included in the documentation submitted for approval, in particular when this may constitute an important element in decision-making, in order to ensure long-term value creation for shareholders. EDP also has a Financial Matters Committee/Audit Committee, the main mission of which, by delegation of the General and Supervisory Board, is to monitor and supervise, on a permanent basis, inter alia, matters related to the internal control system of financial information and the risk management process, in particular in the area of tax.

Refers only to medium voltage. DIVIDEND PAY-OUT RATIO Measures the percentage of a company’s net income that is given to shareholders in the form of dividends (Total Dividends per Share of period “n”/ Earnings per Share of period “n-1”). DIVIDEND YIELD Considers the ratio between gross dividend per share and its share price. DPS (DIVIDEND PER SHARE) Dividend per share (DPS) is the sum of declared dividends issued by a company for every ordinary outstanding share. DPS is calculated by dividing the total dividends paid out by a business, including interim dividends, over a period of time by the number of outstanding ordinary shares issued. E EBIT Earnings before Interest and Tax: EBITDA deducted from provisions, amortizations and impairments. EBITDA Earnings before Interest, Tax, Depreciations and Amortizations: Gross Profit - Supplies and services - Personnel costs and employee benefits +/- Other income/expenses. EBITDA@risk Estimated loss of EBITDA, in a given period of time and for a given confidence interval. Usually it is used an horizon of 12 months and a level of confidence of 95%. EOLICITY Indicator that allows to quantify the deviation of the total value of energy produced by wind in a given period, in relation to an average wind regime. ENERGY BOX Energy Box is a household energy manager that does much more than metering energy, being endowed with technology that supports the supply of electricity services, namely, in remote communications. EPS (Earnings per share) The portion of a company's net profit allocated to each outstanding share of common stock. F FEC Equivalent interruption frequency of energy per consumed unit. Refers only to medium voltage.

G GC (GREEN CERTIFICATE) Tradable commodity resulting from electricity generated using renewable energy sources. GHG (GREENHOUSE GASES) Gases that trap the heat of the sun in the Earth's atmosphere, producing the greenhouse effect. The two major greenhouse gases are water vapor and carbon dioxide. Lesser greenhouse gases include methane, ozone, chlorofluorocarbons, and nitrogen oxides. GROSS PROFIT Includes Revenues from energy sales and services and other minus Cost of energy sales and other. GSF (Generation Scaling Factor) Ratio of the deficit of hydroelectric companies' actual generation volumes to their assured energy delivery. GW (Gigawatt) Unit of electric power equal to 1,000 MW. GWh Equal to 1,000 MW used continuously for one hour. H HEDGING Risk management strategy used in limiting or offsetting probability of loss from fluctuations in the prices of commodities, currencies, indexes, or securities. HYDRO COEFFICIENT Indicator that allows to quantify the deviation of the total value of hydroelectric energy produced in a given period, in relation to an average hydro regime. Values above "1" translate a period with inflows and energy generated above the average ("wet" period) and bellow "1" the reverse ("dry" period). I ICEIT (Installed capacity equivalent interruption time) Indicator that represents the equivalent interruption time of installed power per geographical area of the operator of the distribution network in a given period, excluding extraordinary

Integrated Annual Report 2022 Annexes Annex 9 - Report on the allocation and impact 605 of green finance Annex 9 - Report on the allocation and impact of green finance Sustainable financing Alignment with the SDG Objectives KPIs 2022 Target 2025 Sustainable financing 44% 50% In the end of 2022, sustainable finance amounted to €12.4 billion: (1) €8.7 billion in green bonds; and (2) and €3.7 billion in sustainability-linked loans, which represented 44% of the nominal debt. EDP has a target to have 50% of its funding from sustainable sources by 2025. Our Green Bonds and sustainability-linked loan have promoted a greater alignment of the company’s financial policy with our sustainability strategy, while increasing market awareness for this topic. EDP’s sustainable financing has contributed heavily towards UN Sustainable Development Goal SDG 7: affordable and clean energy and SDG 13: climate action. Green bonds As part of EDP's strategy and to promote greater alignment of its financial policy with its sustainability strategy, in October 2018, the group (through EDP Finance BV) issued its first green bond, amounting to €600 million (senior debt). Since then, and until the end of 2022, EDP has issued approximately €8.7 billion in green bonds: seven senior debt issuances, two of which in US dollars, and five subordinated debt issuances (hybrid). In March 2022, EDP published a new Green Finance Framework. It includes the green financing instruments (for example, green bonds or green loans) issued by EDP, EDP finance BV and EDP Renováveis and its subsidiaries and project companies to finance or refinance wind (onshore and offshore) and solar (PV and CSP) eligible assets and projects. These assets and projects will be included in the portfolio at the current IFRS balance sheet value. Eligible Green Assets will also include acquisitions of companies and equity participations in entities substantially active in wind and solar activities. EDP’s green finance framework is aligned with the International Capital Market Association’s (ICMA) Green Bond Principles 2021, the Loan Market Association’s (LMA) Green Loan Principles 2021 (GLP). The eligible assets and projects financed and refinanced will contribute towards the climate change mitigation objective of the EU Taxonomy. The framework is supported by a second-party review (SPO) from Sustainalytics. This report is part of the commitment to report on an annual and portfolio basis to investors on how the funding was allocated. The data presented here is externally verified. The details about the several issuances and the information included in this report is also available at EDP’s website (under the fixed income section). The approximately €8.7 billion issued in green bonds between 2018 and 2022 were fully allocated by 31 December 2022, with 2.9 billion euros being allocated to new projects wind and solar that came into operation between 2018 and 2022, 5.0 billion euros being allocated to existing projects and 0.8 billion to equity participations and acquisitions. It should be noted that the amount of green funding allocated to new projects corresponds to wind and solar farms that have begun operating at the year of the date of issuance of the respective green bonds. All EDP green issuances are aligned with EDP’s sustainability strategy, as part of EDP’s Strategic Agenda and Business Plan 2021-2025, with the proceeds being used to support its objectives to increase renewable capacity (90% by 2025 and 100% by 2030), and to reduce our scope 1 and 2 specific emissions by 70% by 2025 and 98% by 2030, approved by SBTi in 2021\. These targets are aligned with a 1.5ºC decarbonization trajectory. Recently, in January 2022, EDP has submitted new targets to the SBTi, currently under validation, in line with the new net-zero standard. EDP’s Green Finance Framework EDP published a new Green Finance Framework in March 2022 Green Bonds Issued over the period 2018-2022 €8.7B EDP’s Green Finance Framework SPO Sustainalytics is the opinion that the Framework’s two el- igible activities fully align with the applicable Tech- nical Screening Criteria in the EU Taxonomy and align with the Do No Significant Harm Criteria (fully for three and partially for climate change adaptation). The Framework is compliant with the EU Taxonomy’s Minimum Safeguards. 

Integrated Annual Report 2022 Annexes Annex 9 - Report on the allocation and impact 606 of green finance The impact of the portfolio was 10.8GW of renewable energy capacity, 24.8 TWh of annual renewable energy production and the avoidance of 15.0 MtCO2 of emissions. These impact metrics are consolidated at a portfolio level and not reported at a bond level. It should be noted that, since 2022, following the publication of our 2022 Green Finance Framework, green proceeds can be allocated to acquisitions of companies and equity participations in entities substantially active in wind and solar, which do not have impact KPIs associated, namely installed capacity (MW), production (GWh) and GHG emissions avoided (tCO2). *Bloomberg (January 2023) In terms of geographical split, 65% of the projects financed with green proceeds are in the United States (49%) and Spain (16%). A minority of projects is in the United Kingdom (7%), Romania (6%), Poland (5%), Portugal (5%), Brazil (4%), France (3%), Italy (3%), and Mexico (2%). With negligible weight are projects in the geographies of Greece, Belgium, Canada and Vietnam.

Evaluation and selection of projects Compliance with the objectives of EDP's environmental and social policies, supported by a screening of ESG aspects. Management of the funds obtained The net balance of the funds obtained through the emission of green bonds follows a portfolio approach. The resources shall be used to (re-)finance eligible green projects (wind and solar). Eligible green assets will also include acquisitions of companies and equity participations in entities substantially active in wind and solar. Until the net balance of the finds obtained from green bonds emissions has been fully assigned, EDP will invest the unassigned funds to the portfolio of eligible projects, in treasury liquidity or in the repayment/purchasing of existing debt, according to its own criteria. Net proceeds are expected to be fully allocated within 24 months from the issue date. Report on the application of the funds obtained The report is made based on the following indicators: portfolio value of eligible projects net balance of unused resources quantity and percentage of new projects and existing projects Report on the impacts of the funds obtained The report is made based on the following indicators: Installed capacity (MW) CO2 Emissions avoided (tCO2) Generation of renewable energy (MWh) Note: The CO2 emissions avoided correspond to the emissions that would have occurred if the electricity generated by renewable sources had been produced by thermal power stations. For each country, this is obtained by multiplying the net renewable generation by the emission factor for thermally generated electricity in the country.
