The company’s financial profile shows a number of mixed signals for a hybrid‑bond issuance. Revenue grew strongly from €10.6 bn in 2021 to €20.1 bn in 2022, but profitability is modest with an operating profit of only €0.53 bn (≈2.6 % of revenue) and a net profit of €0.31 bn. The balance sheet is heavily leveraged: total financial liabilities (including current portions) were about €6.3 bn in 2022 while cash on hand was €1.9 bn, giving a net debt of roughly €4.4 bn. Net debt to EBITDA stands at about 3.7× (EBITDA ≈ €1.2 bn), which is above the typical investment‑grade threshold of 3.5× but still within a range that some lenders consider acceptable for a regulated utility. Interest coverage (EBIT / finance costs) is 2.5×, providing a modest buffer.

Cash‑flow metrics are weaker. Cash generated from operating activities fell dramatically to €0.036 bn in 2022 after a large working‑capital outflow (increase in receivables and inventories). When the working‑capital impact is stripped out, operating cash flow before changes is €1.2 bn, yielding free cash flow of roughly €0.5 bn after capex – a positive but thin margin. The company also carries a relatively low equity ratio (≈21 % of total assets) and a net‑debt‑to‑equity ratio of about 1.2×, indicating limited cushion for additional subordinated obligations.

Overall, HERA exhibits moderate leverage and coverage, but the low profitability, thin free cash flow after capex, and high net‑debt‑to‑EBITDA suggest a borderline credit profile. Without an explicit credit rating, the metrics point to a company that could accommodate a hybrid bond but with limited margin for error – fitting the “Marginally Suitable” category.
