To assess suitability for hybrid bonds, we examine Acea S.p.A.’s credit profile, leverage, interest coverage, cash flow stability, and equity cushion based on the provided 2022 data.

**1. Profitability and coverage**
- Revenue grew from €3,972m (FY2021) to €5,138m (FY2022), driven by higher energy prices.
- EBITDA (Gross Profit) increased from €1,256m to €1,305m.
- Net profit attributable to owners of parent declined from €313m to €280m.
- Interest costs: Finance costs were €112m in FY2022 (FY2021: €97m). Interest coverage (EBITDA / finance costs) is approximately 1,305 / 112 = 11.7x, which is very strong.

**2. Leverage**
- Non-current financial liabilities: €4,722m (mostly borrowings and bonds).
- Current financial liabilities: €619m.
- Cash and equivalents: €560m.
- Net debt roughly = (€4,722m + €619m) - €560m = €4,781m.
- Equity: €2,755m.
- Net debt / EBITDA ≈ 4,781 / 1,305 ≈ 3.7x. For a regulated utility with stable cash flows, this is moderate but not excessive.
- Equity / Total assets = 2,755 / 11,339 ≈ 24%. Adequate.

**3. Cash flow stability**
- Operating cash flow: €727m in FY2022, down from €760m, but still robust and covers interest many times over.
- High capex: Investing cash outflows of €863m reflect infrastructure spending, typical for a utility. Free cash flow after capex and dividends is negative, but this is manageable with debt/equity funding.

**4. Hybrid bond specific factors**
- Hybrid bonds require strong, predictable cash flows to support subordinated interest payments and a long-dated or perpetual structure.
- The company is an established Italian multi-utility (water, energy, environment) with a regulated/ quasi-regulated asset base, giving revenue visibility.
- Equity component and retained earnings are solid; group structure is the parent issuer with diversified subsidiaries.
- The slight profit decline and negative free cash flow are noted but not alarming in this sector.
- Market risk: The entity is Italian, implying sovereign-related spread risk, but hybrid issuance from investment-grade utilities in Italy has precedent.

**Conclusion**
Acea’s financial metrics (solid interest coverage, moderate leverage, stable cash generation, regulated business model) make it a suitable candidate for hybrid bonds. The “marginally” qualifier is not needed because the coverage and asset profile are clearly within acceptable ranges for hybrid issuance. There is no insufficiency of data.
