**Reasoning**

- **Strong cash‑flow generation:** Operating cash flow rose sharply from €574 M (2021) to €1,648 M (2022), giving a cash‑flow‑to‑revenue ratio of ~15 %. This demonstrates robust capacity to service hybrid‑bond coupons.
- **Moderate leverage:** Net debt (total interest‑bearing debt less cash & equivalents) is €5.1 bn, yielding a net‑debt/EBITDA of ~2.4× and net‑debt/equity of ~0.8× – well within investment‑grade thresholds for hybrid issuance.
- **Sound interest coverage:** EBIT of €1,334 M covers finance costs of €256 M by ~5.2×, indicating comfortable buffer for additional hybrid‑bond interest.
- **Large asset base:** Non‑current assets of €14.4 bn (≈ 64 % of total assets) provide ample collateral backing for hybrid instruments.
- **Existing hybrid‑type securities:** The company already carries “Participaciones Preferentes” (preferred shares) of over €4 bn, showing market acceptance of hybrid capital and proving the firm can manage such instruments.
- **Profitability trend:** Net profit grew from €404 M to €615 M (+52 %) and EBITDA is ~€2.1 bn, supporting sustainable coupon payments.

All key metrics meet typical criteria for hybrid‑bond issuers (investment‑grade rating, leverage < 4× net‑debt/EBITDA, interest coverage > 3×, strong operating cash flow). Therefore, Acciona S.A. appears well‑positioned to issue hybrid bonds.
