EDF shows volatile earnings with large losses in 2022-2023, negative operating and profit figures, high leverage with substantial noncurrent liabilities and long-term provisions, including nuclear decommissioning, but also large equity and significant post-2022 issuance of equity and financing activities. Hybrid bonds (perpetual subordinated instruments) require stable earnings, solid capitalization, and investor protection signals. EDF’s 2022-2023 period exhibits negative profitability, high comprehensive income fluctuations, and significant borrowing activities. However EDF has substantial equity and large noncontrolling interests, and in prior year issued perpetual subordinated bonds; there is some track record of hybrids. Given mixed signals but elevated risk, not strongly suitable, possibly marginally suitable, but due to weak profitability and high risk, could be considered Not Suitable. I choose Marginally Suitable.
