REN – Redes Energéticas Nacionais appears **Strongly Suitable** for hybrid bond issuance.

REN is a regulated Portuguese energy networks/infrastructure group, with characteristics that are generally favorable for hybrid capital: essential-service assets, high cash-flow visibility, regulated concession/intangible asset base, and established access to debt capital markets. Its business profile is much closer to a regulated utility than to a cyclical industrial or commodity-exposed issuer.

Key considerations:

- **Business profile supports hybrid acceptance.** REN operates national energy transmission/network infrastructure, a natural-monopoly, regulated utility-type business. This is one of the sectors where rating agencies and investors are typically most receptive to hybrids because cash flows are relatively predictable and regulation provides cost-recovery mechanisms.

- **Large stable asset base and recurring operating cash flow.** Total assets were about **€6.45bn** at year-end 2022, with very substantial regulated concession/intangible assets of about **€4.08bn**. Operating cash flow was strong at **€613m** in 2022, despite being lower than 2021’s **€700m**.

- **Investment-grade-type profile, but leverage remains material.** Gross borrowings were about **€2.33bn** at year-end 2022, comprising **€1.70bn long-term borrowings** and **€639m current borrowings**. Cash was **€365m**, implying net debt of roughly **€1.97bn**. EBITDA-like operating cash flow before depreciation can be estimated at about **€489m** from operating profit of **€240m** plus depreciation/amortization of **€249m**, implying net debt/EBITDA around **4.0x**. This is consistent with a regulated utility in the BBB-type area rather than an A-category low-leverage issuer.

- **Hybrid capital could provide meaningful rating-headroom benefit.** For a regulated utility with high debt needs, partial equity credit from a hybrid could improve adjusted leverage, FFO/debt, and financial flexibility without issuing common equity. Given REN’s sizeable borrowings and ongoing capex on concession/intangible assets, the potential benefit is material.

- **Clear refinancing and funding rationale.** REN had a high level of current debt maturities at year-end 2022, with **€639m** of current borrowings/current portion of noncurrent borrowings. It also continues to invest materially, with **€202m** of intangible asset purchases in 2022. Hybrid issuance could support refinancing, preserve liquidity, and fund regulated investment while protecting credit metrics.

- **Capital market credibility appears solid.** The group executed large borrowings and repayments in 2022, with **€1.165bn** of borrowing proceeds and **€1.523bn** of repayments, indicating active capital markets/bank funding access. Cash liquidity of **€365m** also supports market confidence.

- **Interest rate environment was less favorable in 2022, but still compatible.** Euro swap rates rose sharply in 2022, and subordinated spreads increased, making hybrids more expensive than in 2020–2021. However, for a regulated utility with strategic refinancing/capital-structure objectives, hybrid issuance can still be justified if rating equity credit and balance-sheet support are important.

The main caution is that REN’s metrics do not appear distressed: operating profit rose to **€240m**, net profit increased to **€112m**, equity improved to **€1.52bn**, and operating cash flow remains robust. However, the combination of regulated utility status, sizeable refinancing needs, ongoing capex, and BBB-like leverage makes hybrid capital a highly credible and strategically useful instrument rather than merely expensive subordinated debt.
