TenneT Holding B.V. is a regulated electricity transmission‑system operator that operates a critical, monopoly‑type infrastructure network in the Netherlands (and Germany). Its business risk profile is shaped by a strong regulatory environment that allows full and timely recovery of operating and capital costs, provides visible cash‑flows, and supports a stable, compensatory return on the asset base. These characteristics meet the “regulated, quasi‑regulated, infrastructure‑like, utility” criterion for a strongly suitable issuer.

From a financial perspective, the company carries a large debt load (total debt > €21 bn) while Funds from Operations (FFO) are modest – CFO of €1.2 bn plus interest paid yields an estimated FFO/debt ratio of roughly 6‑7 %, which places the financial risk profile in the “weak” region for a regulated utility. The net loss of –€879 m in 2022 and the high capital‑expenditure programme (≈ €4.4 bn in 2022) further indicate deteriorating metrics and a need to bolster equity‑like capital to preserve the current rating.

The existing hybrid capital (€2.125 bn) already provides a portion of equity‑like funding, but the company’s leverage and FFO‑to‑debt metrics would benefit materially from additional hybrid issuance. Issuing a new hybrid bond would improve adjusted leverage, increase rating headroom, and help fund the substantial capex pipeline and refinancing requirements. Moreover, the company has demonstrated access to institutional capital markets and a credible financial policy, and it faces a near‑term refinancing need for the existing hybrid instrument.

All the “Strongly Suitable” criteria are satisfied: regulated utility with visible cash‑flows, investment‑grade profile in the BBB area, material improvement in leverage/FFO‑debt, strong financing rationale, high credibility, and deteriorating financial metrics that necessitate hybrid capital to maintain the rating.

**Conclusion:** The entity is a strong candidate for hybrid‑bond issuance.
