EDP appears to be a credible candidate for hybrid bond issuance, but with some leverage and cash-flow considerations.

Key positives:
- Large, established utility business: EDP operates in electricity generation, transmission, distribution, supply, and gas supply. Utilities are frequent hybrid bond issuers because of stable regulated/contracted cash flows and capital-intensive balance sheets.
- Significant scale: 2022 revenue was about €20.7bn, up from €15.0bn in 2021.
- Positive profitability: net profit was about €1.17bn in 2022, with €679m attributable to owners of the parent. Profit remained positive year-on-year.
- Strong operating cash flow: cash flow from operating activities rose to about €3.78bn in 2022 from €2.02bn in 2021.
- Market access likely: the company already has substantial long-term borrowings and institutional partnership financing, suggesting it is an active capital-markets borrower.
- Hybrid bonds would fit the profile: EDP has heavy investment needs, with investing cash outflows of about €6.08bn and capex-related payments of about €3.50bn in 2022. Hybrid capital could help fund growth while receiving partial equity credit from rating agencies.

Concerns:
- Leverage is substantial: total liabilities were about €45.0bn versus equity of €13.8bn at year-end 2022, and borrowings increased materially, especially current borrowings.
- Negative free cash flow after investing: operating cash flow did not cover investing cash outflows in 2022, requiring financing.
- Equity declined slightly from 2021 year-end to 2022 year-end despite positive earnings, partly due to dividends and OCI effects.
- Finance costs increased sharply to €1.75bn in 2022 from €0.88bn in 2021, indicating sensitivity to interest rates and debt burden.

Overall, EDP has the scale, business stability, profitability, and capital-market profile generally supportive of hybrid bond issuance. However, leverage and funding needs prevent an unqualified “strong” assessment unless external credit ratings and market terms are known. The company is suitable, but with some caution.
