Hera S.p.A. appears to be a **regulated multi-utility / infrastructure-like issuer**, which is generally one of the most suitable sectors for hybrid capital. Its activities are consistent with the regulated utilities framework: essential services, large asset base, and likely significant regulated or quasi-regulated cash flows. This supports investor appetite for subordinated hybrid instruments, especially compared with cyclical or commodity pure-play issuers.

Credit metrics also create a plausible rationale for hybrid issuance. The company’s 2022 S&P Net Debt / EBITDA of **4.23x** is elevated for a BBB-area utility, while S&P FFO / Net Debt of **17.3%** indicates moderate but not weak cash-flow coverage. Moody’s adjusted leverage trend is described as **deteriorating**, which is a key reason a utility might consider hybrids to preserve rating headroom, support capex, or avoid common equity issuance. Balance sheet leverage increased materially, with noncurrent financial liabilities rising from about **€3.7bn to €5.7bn**, while free cash flow was pressured by large working-capital absorption and capex.

However, there are important constraints. Hera had **not issued hybrid bonds in 2021 or 2022** and has **never previously issued hybrids**, which is a strong negative signal under the provided guidance. This suggests hybrid capital is not an established funding tool for the company and may not be part of its recurring financial policy. In addition, the 2022 market environment was materially less attractive than 2020-2021: euro swap rates rose sharply, and subordinated spreads were wider, increasing the cost of hybrid issuance. That would make hybrids less compelling unless the rating-support need were urgent.

Overall, Hera has several characteristics that support hybrid suitability: regulated utility profile, investment-grade-like leverage metrics, large capital needs, and deteriorating leverage. But the absence of any prior hybrid issuance and the higher 2022 cost of subordinated capital prevent a “Strongly Suitable” assessment. The company is better viewed as a credible but not obvious hybrid candidate.
