Hera S.p.A. appears to have several characteristics that can support hybrid bond issuance, but also some constraints.

Key positives:
- Large scale and established issuer profile: 2022 revenue was €20.1bn, almost double 2021, indicating a substantial operating platform.
- Regulated/utility-like business profile is implied by the nature of Hera Group, which generally supports access to long-term capital markets.
- Positive profitability: operating profit remained positive at €533.8m, and profit before tax was stable at €408.8m versus €406.9m in 2021.
- Equity base increased: total equity rose from €3.42bn to €3.64bn.
- Cash position strengthened materially: cash and cash equivalents increased from €885.6m to €1.94bn.
- The company successfully raised substantial long-term funding in 2022, with proceeds from noncurrent borrowings of €2.13bn, suggesting capital-market or lender access.

Key concerns:
- Leverage increased significantly. Total liabilities rose to €13.47bn from €10.61bn, and noncurrent financial liabilities increased sharply to €5.69bn from €3.72bn.
- Operating cash flow deteriorated materially, falling to only €35.7m from €1.05bn in 2021, mainly due to a large working-capital outflow.
- Net profit declined from €372.7m to €305.3m, and profit attributable to owners fell from €333.5m to €255.2m.
- Interest coverage is acceptable but not especially strong: operating profit of €533.8m compared with finance costs of €217.2m gives roughly 2.5x coverage.
- Free cash flow was negative after investing activities, before financing, increasing reliance on external funding.

Assessment:
Hybrid bonds are often suitable for large, capital-intensive utility issuers because they can strengthen rating-agency-adjusted equity while supporting investment needs. Hera’s scale, stable profitability, large equity base, and financing access are supportive. However, the sharp rise in leverage and weak 2022 operating cash flow reduce the strength of the case. Therefore, the company looks suitable, but not strongly so based solely on the provided data.
