**Reasoning**

- **Revenue & Profitability:** Revenue grew strongly from €81.9 bn (2021) to €135.7 bn (2022). Operating profit rose to €11.2 bn and profit before tax to €8.7 bn, indicating solid underlying earnings power.  
- **Cash Flow:** Operating cash flow was €8.7 bn (2022), comfortably covering net interest (≈ €2.4 bn cash) and even leaving a positive cash result after interest. However, after heavy capital expenditures (≈ €13.6 bn) and dividend payments (≈ €4.9 bn), free cash flow before financing turned modestly negative, reflecting the capital‑intensive nature of the utility business.  
- **Leverage:** Net debt is roughly €78 bn (total financial debt ≈ €89 bn minus cash €11 bn). With EBITDA of ≈ €18.6 bn, net‑debt/EBITDA is about 4.2×, a moderate level for a regulated utility but above the lower‑end threshold of 3–3.5× used for “strong” issuers.  
- **Interest Coverage:** EBIT/interest ≈ 4.6× (EBIT of €11.2 bn vs. net finance cost ≈ €2.5 bn), providing decent protection.  
- **Equity Base:** Equity stands at €42 bn (≈ 19 % of total assets). After deducting intangible assets (≈ €17.5 bn, including goodwill), tangible equity falls to ≈ €24.6 bn, lowering the cushion against subordinated obligations.  
- **Existing Hybrid Instruments:** The company already has perpetual hybrid bonds with an equity component of ≈ €5.6 bn, showing it can service hybrid coupons (cash coupon paid in 2022 ≈ €123 mn).  
- **Credit Quality:** While the company is investment‑grade (BBB‑/BBB range typical for large utilities), the modest equity ratio, relatively high net‑debt/EBITDA and negative free cash flow after capex indicate less headroom than a “strong” issuer.  

Overall, the firm meets the basic criteria for hybrid issuance – stable regulated cash flows, acceptable interest coverage, and a track record with hybrid instruments – but the leverage and equity cushion are not exceptionally strong, placing it in a borderline category.
