**Reasoning**

| Criterion | EDF (Entity B) | EDP (Entity A) | Veolia (Entity C) |
|-----------|----------------|----------------|-------------------|
| **Refinancing of existing hybrids** | EDF already has perpetual sub‑ordinated bonds and is actively issuing new hybrids to replace maturing ones (payments to holders ≈ €606 M, proceeds from new issuances ≈ €994 M). The need to refinance existing hybrid debt is immediate. | No existing hybrid debt is reported; the question is **new** issuance, not a refinancing of a current hybrid. | Veolia has deeply‑subordinated securities (≈ €3.5 bn) and repaid € 500 M in 2022, indicating some refinancing activity, but the urgency is lower than for EDF. |
| **Deteriorating credit metrics – rating‑downgrade risk** | 2022 net loss ≈ €‑18 bn; operating cash flow negative (‑€7.4 bn); net debt > €100 bn; credit metrics are significantly weakened and a downgrade would be material. | Net profit ≈ €1.2 bn; operating cash flow ≈ €3.8 bn; net debt/EBITDA ≈ 3.4 x; metrics are solid but debt has risen, creating some pressure. | Profit ≈ €1.0 bn; operating cash flow ≈ €4.1 bn; net debt/EBITDA ≈ 3.4 x; metrics are stable, no clear deterioration. |
| **Hybrid issuance would materially improve adjusted leverage** | Issuing a new hybrid (treated as 50 % equity for rating purposes) would reduce reported leverage and could restore rating headroom, which is critical given the current weak metrics. | A hybrid would improve leverage (net‑debt/EBITDA) but the effect is modest compared with the scale of EDF’s problem. | A hybrid would also help leverage, but the improvement would be incremental rather than decisive. |
| **Cost of hybrid vs. average cost of debt** | EDF’s average cost of debt is low (government‑backed, ~2‑3 %). A hybrid would be priced a few percentage points higher, still marginal for the company’s overall financing cost. | EDP’s average cost of debt is ~5‑6 %; a hybrid would be priced slightly above that, again marginal. | Veolia’s cost of debt is also around 4‑5 %; the hybrid pricing would be modestly higher, still marginal. |
| **Suitability category** | **Strongly suitable** – regulated electricity utility, investment‑grade (BBB area), deteriorating metrics, clear refinancing need. | **Strongly suitable** – energy‑infrastructure utility, investment‑grade, but no immediate refinancing need. | **Strongly suitable** – water/waste‑management utility (regulated‑like), investment‑grade, but less urgent credit pressure. |

Combining the four weighted factors:

1. **Refinancing need** → EDF (most urgent) > Veolia > EDP (no current hybrid to refinance).  
2. **Deteriorating credit / rating‑downgrade risk** → EDF (critical) > EDP (moderate) > Veolia (stable).  
3. **Leverage improvement from hybrid** → EDF (largest impact) > EDP > Veolia.  
4. **Cost & suitability** → all three are strongly suitable, but EDF’s need and risk make it the top priority.

Therefore the bank should engage **EDF first**, **EDP second**, and **Veolia third** for a hybrid‑bond transaction.
