To prioritize hybrid bond origination prospects, I would look for: (1) demonstrated willingness to use hybrids, (2) balance-sheet need for equity credit or leverage support, (3) investment/capex funding needs, (4) ability to access capital markets, and (5) relative urgency.

**Entity C — Terna — strongest first target.**  
Terna is the clearest prospect because it already issued a sizeable hybrid/perpetual equity instrument in 2022: **“Equity Instruments Perpetual Hybrid Bonds” of €989m**. That is direct evidence of appetite and internal acceptance of hybrid capital. It also has heavy grid investment needs, with capex-like investing cash outflows of about **€1.86bn** and PPE purchases of about **€1.49bn**, while maintaining a regulated infrastructure profile and solid profitability. Its leverage is meaningful, but operating cash flow is strong and positive. Since it has recently used hybrids, a bank could realistically pitch a follow-on, refinancing, or benchmark-sized additional hybrid.

**Entity A — Redeia — second target.**  
Redeia is also a regulated electricity infrastructure issuer with stable earnings and cash flows, making it a plausible hybrid candidate. It has meaningful debt and significant investment activity, and hybrids could help support credit metrics while funding infrastructure growth. However, unlike Terna, there is no explicit evidence in the data that it has recently issued hybrid/perpetual equity instruments. Its balance sheet also improved materially in 2022, with equity rising strongly and current financial liabilities falling, so urgency appears lower than for a repeat issuer like Terna. Still, it is a high-quality infrastructure name and likely a credible second prospect.

**Entity B — EDF — third target.**  
EDF has by far the largest financing need and already has hybrid-like instruments, including payments and issuance/redemption of perpetual subordinated bonds and convertible instruments. However, it reported a very large 2022 loss, negative operating cash flow, heavy leverage, and substantial state influence. While this could imply need for capital, it also makes hybrid origination more complex: investor appetite, ratings treatment, state ownership dynamics, and broader restructuring/government support considerations may dominate. EDF may issue capital instruments, but as a bank origination prospect it is less straightforward and less “promising” than the cleaner regulated grid names, especially Terna.
