To assess the suitability of Acciona S.A. for issuing hybrid bonds, we examine its financial position and capacity to absorb the characteristics of hybrid instruments:

1.  **Profitability and Earnings Quality**: The company demonstrates strong growth in Revenue (from 8.1 billion EUR in 2021 to 11.2 billion EUR in 2022) and an increase in Profit/Loss from Continuing Operations (from 404 million EUR to 615 million EUR). The positive Operating Cash Flow (1.65 billion EUR in 2022) indicates a robust ability to generate the cash required to service interest/coupons.
2.  **Solvency and Leverage**: As of the end of 2022, Acciona has a significant amount of "Participaciones Preferentes Obligaciones YOtros Valores Negociables No Corrientes" (3.1 billion EUR), indicating prior experience with and an existing base of hybrid-like instruments or long-term debt.
3.  **Financial Stability**: The company’s Equity is substantial (6.3 billion EUR) compared to total liabilities. While there is significant debt, the cash position remains strong at 2.36 billion EUR.
4.  **Strategic Context**: Companies in capital-intensive sectors like infrastructure and renewables (Acciona's primary business) often utilize hybrid bonds to optimize their capital structure, maintain credit ratings, and finance long-term assets without diluting equity. Given the consistent profitability and high capital expenditure requirements (Purchase of PPE/Intangible assets of 2.19 billion EUR), hybrid bonds serve as an efficient tool to bridge financing needs while preserving equity credit.

Given the existing presence of similar financial instruments in the capital structure and the strong operating performance, the company is well-positioned to issue such debt.
