The arbitral tribunal has confirmed Diana BidCo Oy's redemption right over the minority shares in WithSecure Corporation, and trading in the WithSecure Corporation shares has been suspended

The arbitral tribunal appointed by the Redemption Board of the Finland Chamber of Commerce in connection with the redemption proceedings concerning the minority shares in WithSecure Corporation (“WithSecure”) has in its interim decision confirmed that Diana BidCo Oy (“Diana BidCo”) has the right to redeem the minority shares in WithSecure, and that Diana BidCo has the right to obtain title to the minority shares by posting a security approved by the arbitral tribunal for the payment of the redemption price and the interest accruing thereon.

WithSecure announced on 13 March 2026 that the Board of Directors of WithSecure has resolved to apply for the termination of public trading in the shares of WithSecure and for the delisting of its shares from the official list of Nasdaq Helsinki Ltd (“Nasdaq Helsinki”) so that the delisting in respect of the WithSecure shares admitted to trading on the official list of Nasdaq Helsinki would become effective as soon as possible after Diana BidCo has gained title to all the shares in WithSecure in the pending redemption proceedings under Chapter 18 of the Finnish Companies Act.

Following the confirmation of Diana BidCo's redemption right, Nasdaq Helsinki has suspended trading in the WithSecure shares today on 25 March 2026 before the opening of trading. The possible posting of the security and the delisting of the WithSecure shares will be announced separately.
