**Reasoning**
| Entity | Regulatory status & cash‑flow visibility | Credit‑metric trend (FY 2022 vs FY 2021) | Net debt / EBITDA (approx.) | Existing hybrid | Need for hybrid (refinancing / rating‑headroom / capex) | Suitability class |
|--------|-------------------------------------------|------------------------------------------|-----------------------------|----------------|----------------------------------------------------------|-------------------|
| **A – TenneT Holding B.V.** | Regulated transmission‑system operator (TSO) – highly visible, recurring transmission‑charge revenues (€7.5 bn FY 2022). | • Operating loss widened from –€275 m to –€976 m.
• Net profit turned more negative (–€879 m vs –€340 m).
• Long‑term borrowings surged from €12.4 bn to €19.0 bn, pushing leverage to ~55× Net‑debt/EBITDA. | ~55× (Net debt ≈ €14 bn; EBITDA ≈ €0.26 bn) | €2.125 bn hybrid capital (both years) – existing hybrid that may be callable in the near term. | Deteriorating metrics expose the group to a potential rating downgrade; a new hybrid would provide rating headroom, help refinance the existing hybrid and fund a large capex programme (≈ €4.4 bn in FY 2022). | **Strongly Suitable** |
| **B – REDEIA Corporación S.A.** | Regulated electricity‑grid operator – stable, regulated cash flows (revenue €2.0 bn). | • Profit from operating activities essentially flat (≈ €962 m).
• Net profit stable (≈ €681 m).
• Debt modest (net debt ≈ €5.4 bn; Net‑debt/EBITDA ≈ 3.6×). | ~3.6× (Net debt ≈ €5.4 bn; EBITDA ≈ €1.5 bn) | No hybrid capital reported. | No immediate refinancing need; moderate leverage means a hybrid would only modestly improve ratios, but the company has a sizable capex pipeline (≈ €0.5 bn FY 2022) and could use a hybrid for funding flexibility. | **Strongly Suitable** (but less urgent than A) |
| **C – ENGIE** | Large, diversified energy group; only partially regulated (transmission/distribution assets are a minority). Cash‑flow visibility moderate. | • Operating profit fell sharply from €6.7 bn to €1.1 bn.
• Net profit dropped from €3.8 bn to €0.39 bn.
• Net‑debt/EBITDA ≈ 4.0× (moderate, but trending upward). | ~4.0× (Net debt ≈ €25 bn; EBITDA ≈ €6.3 bn) | Deeply‑subordinated perpetual notes €3.4 bn (treated as hybrid equity). | Existing hybrid is perpetual; no imminent refinancing requirement. Improvement in leverage from a new hybrid would be modest; the group’s financing needs are already covered by a broad capital‑markets access. | **Marginally Suitable** |
**Prioritisation**
1. **TenneT (A)** – meets the “strongly suitable” profile: regulated utility, investment‑grade, deteriorating credit metrics, existing hybrid requiring refinancing, and a clear capex‑funding rationale. Issuing a hybrid would give the most rating headroom and address the refinancing need, making it the top target for a hybrid‑bond origination.
2. **REDEIA (B)** – also a regulated utility with strong cash‑flow visibility and a stable credit profile. While it does not have an existing hybrid, it could benefit from a hybrid issuance to support its capex programme and modestly improve leverage. It is a strong candidate, but less urgent than TenneT.
3. **ENGIE (C)** – classified as marginally suitable (industrial, partially regulated). It already carries a hybrid (perpetual notes) and its credit metrics, while softening, are not under the same pressure as TenneT’s. A new hybrid would be opportunistic rather than a critical refinancing tool, making it the lowest priority.
