The priority order should be **A first, C second, B third**.

**1) Entity A — TenneT Holding B.V. — highest priority**

TenneT is the strongest candidate for proactive hybrid bond origination.

Key reasons:

- **Very strong sector fit:** TenneT is a transmission system operator, a regulated energy infrastructure business with highly visible cash flows. This fits the “Strongly Suitable” category very well.
- **Existing hybrid capital:** TenneT already has **€2.125bn of hybrid capital**, with annual hybrid distributions of **€57m**, showing it is already an established hybrid issuer and likely has investor acceptance.
- **Large capex and funding need:** Capex was very substantial, with purchases of PPE/intangibles of about **€4.4bn in 2022**, up from **€3.7bn in 2021**. The balance sheet expanded materially, with assets rising from **€31.2bn to €38.5bn**.
- **Deteriorating credit metrics / leverage pressure:** Long-term borrowings rose sharply from **€12.4bn to €19.0bn**, while the company reported a **net loss of €879m** and negative operating profit. This creates a clear credit-metric and rating-headroom rationale for hybrid issuance.
- **Hybrid would materially support adjusted leverage:** Given the scale of debt growth and capex funding, additional hybrid capital could improve rating-agency adjusted leverage and help preserve rating headroom.
- **Shareholder support but continued funding need:** The Dutch State provided a **€1.23bn capital contribution**, but debt still increased significantly. Hybrid issuance would be a logical complement to state equity and senior debt.

Overall, TenneT is a regulated infrastructure issuer with high capex, deteriorating metrics, existing hybrid capital, and a strong rating-preservation rationale. It should be approached first.

**2) Entity C — ENGIE — second priority**

ENGIE is also a credible hybrid candidate, but the rationale is less urgent than for TenneT.

Key reasons:

- **Strong issuer scale and capital markets credibility:** ENGIE is a major European energy utility with very large institutional market access.
- **Existing hybrid-like capital:** ENGIE has **deeply subordinated perpetual notes**, declining from **€3.767bn to €3.393bn** during 2022, with “operations on deeply subordinated perpetual notes” of **€451m**. This indicates an existing hybrid framework and possible refinancing activity.
- **Large balance sheet and leverage relevance:** ENGIE has very large borrowings, including **€28.1bn long-term borrowings** and **€12.5bn current borrowings**. A hybrid could be material for adjusted leverage and rating headroom.
- **Mixed but not clearly distressed credit picture:** Operating cash flow was strong at **€8.6bn**, and cash was high at **€15.6bn**. However, reported net income fell sharply to **€390m**, profit attributable to owners was only **€216m**, and continuing operations were loss-making. This creates some credit-metric pressure, but ENGIE’s liquidity and scale reduce urgency.
- **Partially regulated / diversified energy profile:** ENGIE has regulated and infrastructure-like elements, but it is broader and more exposed to commodity/energy market volatility than a pure transmission grid operator like TenneT.

ENGIE is suitable, likely between strongly and marginally suitable depending on rating context and hybrid call schedule. It should be engaged second, especially if there is a known call/refinancing window for its deeply subordinated notes.

**3) Entity B — Redeia Corporación SA — third priority**

Redeia is a high-quality regulated infrastructure issuer, but it appears less urgent as a hybrid origination target.

Key reasons:

- **Strong sector fit:** Redeia is an electricity transmission/infrastructure group, so its business profile is highly compatible with hybrid issuance.
- **Stable profitability and cash flow:** It generated operating profit of about **€962m**, net profit of **€681m**, and operating cash flow of **€1.57bn**. These are stable and supportive metrics.
- **Improved equity and leverage position:** Equity rose materially from **€3.69bn to €4.89bn**, while long-term borrowings declined from **€5.90bn to €5.49bn** and current borrowings also decreased. This suggests improving rather than deteriorating credit metrics.
- **No evident existing hybrid refinancing trigger:** Unlike TenneT and ENGIE, the data does not show existing hybrid capital or deeply subordinated perpetual notes requiring refinancing.
- **Hybrid rationale is more opportunistic:** Redeia could issue hybrid debt to increase rating headroom, fund investments, or optimize capital structure, but the urgency is lower because its leverage and earnings profile appear relatively stable.

Redeia is a credible issuer but appears more “marginally suitable” or lower-priority “strong suitable” because there is no clear deterioration or refinancing need.
