To prioritize likely hybrid bond origination prospects, I would focus on: existing hybrid/perpetual subordinated capital market behavior, leverage/funding need, equity-credit motivation, and ability/need to refinance or add rating-agency-friendly capital.

**Entity B — EDF — should be first.** EDF has the strongest immediate rationale for hybrid capital: it suffered a very large 2022 loss, negative operating cash flow, heavy capex, and a major increase in borrowing. Equity fell sharply from EUR 62.0bn to EUR 46.6bn, while financing cash inflows were very large. It also has an established precedent of issuing subordinated/hybrid instruments: proceeds from subordinated liabilities and convertible instruments were EUR 994m in 2022 and EUR 1.235bn in 2021, with payments to holders of perpetual subordinated bonds. This combination of demonstrated market access, large balance-sheet pressure, capital intensity, and need for rating support makes EDF the most promising hybrid bond target.

**Entity C — Veolia — should be second.** Veolia is also clearly hybrid-relevant. It has outstanding deeply subordinated securities, including a sizeable increase linked to Suez hybrid debt contribution, and it paid coupons on these instruments. The Suez acquisition materially expanded its balance sheet, goodwill, assets, financial liabilities, and integration-related funding needs. However, unlike EDF, Veolia remained profitable, generated positive operating cash flow, and had a much stronger 2022 performance profile. It is a good prospect, especially for refinancing or optimizing its hybrid stack, but the urgency is lower than EDF’s.

**Entity A — EDP — should be third.** EDP is capital intensive and has rising borrowings, but it remained profitable, generated positive operating cash flow, and does not show explicit existing hybrid/perpetual subordinated securities issuance in the data. It already has meaningful equity, stable earnings, and less visible immediate need for hybrid capital compared with EDF and Veolia. It is still a possible utility hybrid candidate, but less compelling from the provided evidence.
