**Reasoning**

To gauge the suitability for issuing hybrid bonds, we examine key credit and financial metrics:

| Metric | 2022 (or FY end) | Commentary |
|---|---|---|
| **EBIT (Operating profit)** | €533.8 M | Provides core earnings power. |
| **Depreciation & Amortisation** | €667.1 M | Adds back to obtain an approximate EBITDA of ~€1.2 bn. |
| **Net debt** (total debt – cash) | €4.5 bn (debt €6.4 bn – cash €1.9 bn) | Moderate‑high leverage. |
| **Net debt / EBITDA** | ≈ 3.7× | Slightly above the typical investment‑grade threshold of 3.5×, indicating limited headroom. |
| **Interest expense (finance costs)** | €217.2 M | – |
| **EBIT / Interest coverage** | ≈ 2.5× | Below the 3× level often required for senior debt, but still positive. |
| **Operating cash flow before working‑capital changes** | €1.2 bn | Strong; covers interest more than 9× on a cash basis. |
| **Operating cash flow after working‑capital changes** | €35.7 M | Sharp decline due to large working‑capital outflows (receivables & inventories) – a risk factor if growth continues. |
| **Total debt / total assets** | ≈ 37.5 % | Moderate, but equity base is relatively thin (≈ 21 % of assets). |
| **Profitability (net profit)** | €305 M (≈ 8 % ROE) | Adequate for a utility, but not exceptionally high. |
| **Cash flow from financing** | €1.78 bn (large borrowing) | Demonstrates ability to access capital markets, an essential prerequisite for hybrid issuance. |

Hybrid bonds are generally suited to issuers that:
1. Have investment‑grade credit ratings (or at least strong coverage ratios).
2. Exhibit stable, predictable cash flows.
3. Maintain leverage within acceptable limits (net debt/EBITDA ≤ 4× for many hybrid investors).
4. Possess adequate equity‑like buffers (hybrids are treated as 50 % equity in rating agency capital calculations).

**Assessment**

- The company generates robust operating cash flows before working‑capital changes, and its EBITDA (~€1.2 bn) comfortably covers interest on a cash basis.
- However, net debt/EBITDA of ~3.7× and EBIT/interest coverage of ~2.5× sit on the borderline of what many hybrid‑bond investors consider acceptable.
- The thin equity layer (≈ 21 % of assets) and the large working‑capital outflows in 2022 introduce some uncertainty regarding near‑term cash flow stability.
- The firm’s ability to raise €2.1 bn in new borrowings shows market confidence, yet the high leverage and modest coverage ratios indicate that the company is not a “best‑in‑class” candidate.

Overall, the balance of strengths and weaknesses places the issuer in the **marginally suitable** category for hybrid‑bond issuance.
