Fortum Corporation STOCK EXCHANGE RELEASE 25.1.2005

FORTUM REASSERTS ITS CALL OPTION OVER E.ON FINLAND SHARES Fortum Oyj has received a reply from E.ON Nordic regarding its call option to the shares in E.ON Finland owned by E.ON Nordic. Referring to its 2001 shareholders´ agreement with the City of Espoo, E.ON states that it is not in a position to sell its shares in E.ON Finland. According to Fortum, E.ON´s refusal is unfounded. As a result, Fortum will commence the necessary legal proceedings to secure its rights. In its reply, however, E.ON Nordic has stated that it will have to evaluate the situation differently if the City of Espoo accepts Fortum´s offer for the shares in E.ON Finland owned by the City. Moreover, the 2003 shareholders´ agreement between E.ON Nordic and the City of Espoo states that E.ON can sell its shares if the City accepts the transaction. Fortum has made a 257 million euro offer to acquire the shares of E.ON Finland owned by the City. This offer is still valid.
