Yeah in Finland Fortum owns Fortum Power and Heat that owns the 2 reactors in Loviisa and ~25% of TVO.
TVO is the other nuclear company that owns the 3 reactors in Olkiluoto. The other owners of TVO is Pohjolan Voima with ~60% which is owned by the wood/paper companies UPM-Kymmene and Stora-Enso together with a bunch of smaller municipal power companies. Helen (fully owned by Helsinki city) also owns the last ~15% of TVO though its subsidiary Oy Mankala Ab.
Importantly in Finland this ownership structure also plays into how the plants operate. In the case of TVO it does not directly sell its power to end users but to its owners at cost (who are also mandated to buy it) who then use it themselves or sell it forwards.
