Hera S.p.A. appears to be a large, established utility group with substantial revenues and asset base, which is generally supportive for hybrid bond issuance.

Key considerations:

- Scale is strong: 2022 revenue was about EUR 20.1 billion, almost double 2021 revenue, and total assets were about EUR 17.1 billion at year-end 2022. This indicates significant market presence and funding capacity.
- Business profile is likely supportive: Hera is an Italian multi-utility group, and regulated or essential-service utilities are common hybrid bond issuers because they often have stable cash flows and large capital investment needs.
- Profitability remains positive: profit before tax was EUR 408.8 million in 2022, broadly stable versus EUR 406.9 million in 2021. Net profit was EUR 305.3 million, though down from EUR 372.7 million.
- Leverage is elevated but not prohibitive for a utility: liabilities were EUR 13.47 billion versus equity of EUR 3.64 billion, giving a high liabilities-to-equity ratio. Financial liabilities also increased significantly, especially noncurrent borrowings. Hybrid bonds could help support credit metrics by receiving partial equity treatment.
- Cash flow is a concern: operating cash flow fell sharply to EUR 35.7 million in 2022 from EUR 1.05 billion in 2021, mainly due to working-capital absorption. Free cash flow after investments was strongly negative. This weakens the case for “Strongly Suitable.”
- Interest coverage is acceptable but pressured: operating profit of EUR 533.8 million versus finance costs of EUR 217.2 million implies coverage of roughly 2.5x. This is serviceable but not especially robust.
- Capital markets rationale exists: the company has large capex needs, rising debt, and a sizeable equity base. A hybrid bond could be suitable to strengthen capitalization without immediate shareholder dilution.

Overall, Hera has the scale, utility-sector profile, positive earnings, and capital structure rationale to issue hybrid bonds, but weak 2022 operating cash flow and elevated leverage make the suitability less than clearly strong.
