Fortum shows large negative Profit Loss in Discontinued Operations and overall Comprehensive Income negative, but operating cash flows and EBITDA metrics are modest; there is significant equity decline and large noncontrolling interests changes. Hybrid bonds typically require stable earnings, predictable cash flows, and solid equity base. The data shows volatility and large one-off items (Discontinued Ops), and equity decline from 2022 to 2023, though equity attributable to owners of parent remains positive. Also high negative profit loss attributed to discontinued operations indicates potential risk. However, Fortum is a large energy company with ongoing operations and available headroom in liquidity (Cash and cash equivalents), but covenants unknown. Given mixed signals and lack of clear stability, I would categorize as Marginally Suitable, not strongly suitable.
