Fortum to support Uniper dividend proposal

FORTUM CORPORATION STOCK EXCHANGE RELEASE 21 MARCH 2018 9.00 EET

On 26 February 2018, Uniper's management board proposed to have a dividend of EUR 0.74 cents per share for the financial year 2017 distributed by resolution of the Ordinary Annual General Meeting (AGM) scheduled to be held on 6 June 2018. Following such proposal, Fortum Corporation and E.ON SE have agreed that, in the event that Fortum's public takeover offer to all Uniper shareholders closes after Uniper's AGM, E.ONshall be free to vote for the dividend in the amount of EUR 0.74, or any other amount higher than EUR 0.69 per Uniper share up to EUR 0.74 per share. In addition, E.ONhas agreed to compensate Fortum in the amount the dividend exceeds EUR 0.69 per share, multiplied by the number of shares for which the PTO has been accepted i.e. 172,439,375 Uniper shares, representing a total acceptance rate of 47.12%. In the event a dividend of EUR 0.74 per share is resolved, E.ONwould pay to Fortum an amount of approximately EUR 8.6 million.

"We support Uniper's commitment to drive shareholder value including the distribution of attractive dividends," said Pekka Lundmark, President and CEO of Fortum.

If the public takeover offer closes prior to Uniper's AGM, resulting in Fortum having voting rights, Fortum would also support Uniper's proposed dividend distribution of EUR 0.74 cents per share.
