ENEL shows solid operating cash flows (≈ €8.7 bn) and positive profitability (operating profit ≈ €11 bn, net profit ≈ €2.9 bn). Its net‑debt/EBITDA ratio of roughly 4.2× is moderate for a utility, and the company already has €5.6 bn of hybrid bonds outstanding with scheduled coupon payments, indicating it can service hybrid instruments. However, key credit metrics are weak: interest coverage (EBIT/finance costs) is only about 1.9×, the equity‑to‑assets ratio is low (~19 %), and total financial debt is high (≈ €89 bn). These factors limit the company’s capacity to take on additional subordinated debt without increasing financial risk. Therefore, while ENEL can access the hybrid market, the metrics suggest only marginal suitability for further hybrid‑bond issuance.
