**Reasoning**

| Issuer | Sector & Regulatory Status | Credit Metrics (2022) | Existing Hybrid Capital | Need for Hybrid Issuance | Suitability Category |
|--------|----------------------------|-----------------------|-------------------------|--------------------------|----------------------|
| **Ørsted A/S** | Renewable energy infrastructure (off‑shore wind). Long‑term contracts give highly visible cash flows; treated as quasi‑regulated / utility‑like. | Net debt/EBITDA ≈ 1.5×; interest coverage ≈ 8×. Strong investment‑grade profile (BBB area). | Hybrid capital ≈ 19.8 bn DKK (≈ 2.8 bn EUR) – perpetual hybrid bonds with coupon payments. | Large capex (≈ 33 bn DKK) and possible refinancing of the existing hybrid; however leverage is already low, so a new hybrid would only modestly improve ratios. | **Strongly suitable** – regulated‑like, investment‑grade, visible cash flows, strong funding rationale. |
| **Enel SpA** | Global electricity utility (generation & distribution) – partly regulated. | Net debt/EBITDA ≈ 4.2×; interest coverage ≈ 4.6×. Higher leverage and thus more vulnerable to a downgrade if metrics deteriorate. | Hybrid bonds ≈ 5.6 bn EUR (perpetual). Coupon payments ongoing; issuance in 2021‑2022 shows active hybrid program. | Massive capex (≈ 13 bn EUR) and high leverage make a hybrid issuance highly effective to improve adjusted leverage, FFO/debt and rating headroom. Refinancing of the existing hybrid is also a driver. | **Strongly suitable** – utility, investment‑grade, clear leverage improvement, refinancing need. |
| **A2A Energia S.p.A.** | Partially regulated Italian energy utility; moderate cash‑flow visibility. | Net debt/EBITDA ≈ 2.9×; interest coverage ≈ 7.6×. Leverage is moderate, not under immediate pressure. | No existing hybrid capital. | Opportunistic – would use hybrid for M&A, refinancing or to avoid equity; impact on leverage is modest and pricing may be more sensitive. | **Marginally suitable** – industrial/partial‑regulated, moderate cash‑flow visibility, not a core recurring funding instrument. |

**Applying the KPIs**

1. **Refinancing of existing hybrids** – Both Ørsted and Enel have outstanding hybrids, giving them a funding rationale. A2A has none.  
2. **Deteriorating credit metrics** – Enel’s high leverage (≈ 4.2×) makes it most exposed to a potential downgrade; Ørsted’s metrics are strong; A2A is moderate.  
3. **Material improvement in adjusted leverage** – A new hybrid would have the greatest effect for Enel (reduce net‑debt/EBITDA from ≈ 4.2× to ≈ 3.8×). Ørsted’s improvement would be modest; A2A’s limited.  
4. **Cost of hybrid vs. average cost of debt** – For investment‑grade issuers (Ørsted, Enel) the incremental cost of a hybrid is marginal; for A2A (lower rating) the spread is likely larger, making the transaction less attractive.  
5. **Category** – Ørsted and Enel are **Strongly suitable**; A2A is **Marginally suitable**.

**Ranking**

- **First priority:** **Enel (B)** – highest leverage, clear rating‑down‑pressure, existing hybrid needing refinancing, and a hybrid would materially improve leverage and rating headroom.  
- **Second priority:** **Ørsted (A)** – strongly suitable, large capex needs, existing hybrid, but less credit‑risk pressure and lower leverage benefit.  
- **Third priority:** **A2A (C)** – marginally suitable, no existing hybrid, modest leverage improvement, and higher cost of hybrid relative to debt.

Thus the bank should engage Enel first, then Ørsted, then A2A.
