Acciona S.A. appears **suitable for hybrid bond issuance, but not at the strongest level** based on the financial profile and business characteristics provided.

Acciona has several features that support hybrid suitability:

- **Infrastructure and energy-linked business profile:** Acciona is a large Spanish infrastructure, construction, concessions, and renewable-energy group. Its asset base is capital intensive, with very large property, plant and equipment of about **€9.5 billion** and total assets of **€22.6 billion** at year-end 2022. This gives it an infrastructure-like profile, although not a pure regulated utility.
- **Large capex and funding rationale:** The company is investing heavily. Cash capex for property, plant, equipment, intangibles, investment property, and other noncurrent assets was about **€2.2 billion** in 2022, well above operating cash flow of **€1.65 billion**. Investing cash flow was negative **€1.94 billion**. This creates a clear rationale for long-term capital funding, including hybrid capital, especially to support renewables and infrastructure growth without excessive senior debt.
- **Market access and issuer credibility:** Acciona is a sizeable listed Spanish S.A. with established access to debt markets. It issued about **€4.0 billion** of financial debt instruments in 2022 and repaid about **€3.2 billion**, suggesting active capital markets access and refinancing capability.
- **Positive operating performance:** Revenue increased strongly to **€11.2 billion** from **€8.1 billion**, operating profit rose to **€1.33 billion** from **€829 million**, and net profit attributable to owners rose to **€441 million** from **€332 million**. Operating cash flow also improved materially to **€1.65 billion** from **€574 million**.
- **Hybrid could improve adjusted leverage/headroom:** Reported debt-like financial obligations are substantial. Noncurrent bonds/preferred/marketable securities plus noncurrent loans and lease liabilities total around **€6.16 billion**, and current equivalents add roughly **€1.76 billion**, for gross financial debt around **€7.9 billion** before considering cash. Cash is sizeable at **€2.36 billion**, giving approximate net financial debt around **€5.6 billion**. A hybrid instrument receiving partial equity credit could support leverage metrics and preserve rating flexibility during a heavy investment cycle.

However, the case is not clearly “Strongly Suitable”:

- **Not a pure regulated utility:** Acciona has meaningful exposure to construction, infrastructure development, and unregulated renewable generation. Cash flows are more visible than a typical industrial company, but less predictable than a fully regulated network utility.
- **Financial metrics are improving, not deteriorating:** 2022 showed stronger revenue, operating profit, net income, and operating cash flow. Equity also increased from **€5.56 billion** to **€6.30 billion**. This weakens the argument that hybrid issuance is urgently needed to preserve an existing rating.
- **Leverage is meaningful but not distressed:** The company has significant debt and capex needs, but also strong liquidity, positive profitability, and access to refinancing. A hybrid would likely be helpful rather than essential.
- **Market conditions became less favorable in 2022:** EUR swap rates rose sharply, and subordinated spreads widened. Hybrid issuance would be feasible for an issuer like Acciona, but pricing would be more sensitive than in 2020-2021.

Overall, Acciona fits best as an **infrastructure-adjacent / partially regulated energy and infrastructure issuer with moderate-to-good cash flow visibility**, meaningful growth capex, and likely capital market access. Hybrid bonds could provide useful rating and leverage headroom, but the issuance would likely be more opportunistic or growth-funding oriented than strictly necessary.
