To prioritize prospects for a hybrid bond transaction, I would look for issuers that combine: large financing needs, demonstrated access to hybrid/perpetual capital, balance-sheet motivation to preserve credit metrics, and a plausible capacity to absorb another hybrid issue.

**Entity C — Iberdrola — strongest first prospect.** Iberdrola is a very large, investment-grade utility with substantial capital needs and an active financing profile. It has sizeable assets and infrastructure capex, with 2022 investing cash outflow of about €10.2bn and continuing growth in property, plant and equipment. It also has meaningful debt/refinancing activity, issuing/drawing about €14.8bn of debt while repaying about €10.3bn. Importantly, it has clear precedent in hybrid/perpetual-style funding: it issued €2.74bn of perpetual subordinated obligations in 2021, and continued paying hybrid interest in 2022. Its profitability and cash generation remain strong, with 2022 profit attributable to owners of €4.34bn and operating cash flow of €10.44bn. This makes Iberdrola the most promising target: sizeable recurring capital needs, proven hybrid investor acceptance, and a strategic reason to optimize credit metrics.

**Entity A — EDF — second prospect.** EDF has by far the largest absolute financing requirement and issued hybrid/subordinated capital in both years, including proceeds from subordinated liabilities and convertible instruments of roughly €994m in 2022 and €1.235bn in 2021. It also had very large borrowing activity in 2022, with borrowings proceeds of €34.2bn. However, it is a weaker near-term origination prospect than Iberdrola because 2022 financial performance was severely stressed: operating loss of €19.4bn, net loss of €18.2bn, negative operating cash flow of €7.4bn, and equity fell sharply. Although EDF’s scale and prior hybrid use make it relevant, execution could be more dependent on state support, timing, ratings constraints, and investor appetite after a difficult year.

**Entity B — Terna — third prospect.** Terna is financially healthy and already completed a sizeable hybrid/perpetual bond transaction in 2022, with €989m of equity instruments/perpetual hybrid bonds recognized in equity. Its regulated profile and profitability are attractive, but that recent issue reduces immediate urgency for another hybrid. Its capital needs are also much smaller than Iberdrola’s or EDF’s, with 2022 investing cash outflow of about €1.86bn and operating cash flow of €2.32bn. Terna is a credible repeat issuer but less urgent and less sizeable as a near-term origination target.
