To assess whether Acciona S.A. is suitable to issue hybrid bonds, we look at several key financial indicators from the provided 2022 report:

1.  **Profitability:** Acciona has shown strong growth, with revenue increasing from 8,104 million EUR (2021) to 11,195 million EUR (2022). Profit for the period grew from 404 million EUR to 615 million EUR, and profit attributable to the parent reached 441 million EUR.
2.  **Solvency and Leverage:** The company maintains a significant level of non-current liabilities (8,467 million EUR in 2022) and has a substantial equity base (6,304 million EUR). While the company is capital-intensive, the growth in "Equity Attributable to Owners of Parent" (from 4,312 million EUR to 4,885 million EUR) indicates a healthy strengthening of the balance sheet.
3.  **Cash Flow:** Operating cash flow is robust (1,648 million EUR in 2022), providing a solid cushion to cover potential interest payments on hybrid instruments. The ability to manage large capital expenditures (2,195 million EUR in investing activities) while maintaining positive free cash flow metrics suggests strong operational health.
4.  **Nature of Business:** Acciona operates in infrastructure and energy, sectors that typically require long-term, stable capital structures. Hybrid bonds (which can be treated as equity for rating purposes) are a common tool for companies with heavy asset bases to manage leverage ratios while maintaining or improving credit ratings.

Given the consistent profitability, positive cash flow generation, and the capital-intensive nature of their operations (which aligns well with the structural benefits of hybrid debt for optimizing balance sheets), Acciona demonstrates the financial profile and maturity expected of an issuer of hybrid bonds.
