Regulatory press release

The board of Yubico has resolved on repurchase of own ordinary shares

The board of Yubico AB ("Yubico") has resolved to utilize the authorization from the Annual General Meeting held on 13 May 2025, regarding the repurchase of own shares. The purpose of the repurchase is to hold the shares in treasury in order to utilize the shares in connection with potential future acquisition opportunities and to give the board additional flexibility in its efforts to deliver long-term shareholder value and total return.

Repurchase shall take place in accordance with Nasdaq Stockholm's Rulebook for Issuers of Shares and may take place on one or more occasions during the period up until Yubico's Annual General Meeting 2026, whereby ordinary shares for a maximum amount of SEK 200 million may be repurchased.

Yubico's holding of own ordinary shares following repurchase may pursuant to the resolution by the Annual General Meeting at no point in time exceed five (5) percent of all of the shares in Yubico. Repurchase shall be made on Nasdaq Stockholm at a price per share which is within the at each time registered price interval, which is the interval between the highest buying price and the lowest selling price. Where the repurchase is effected by a stock broker as assigned by the company, the price of shares may, however, correspond to the volume weighted average price during the time period within which the shares were acquired, even if the volume weighted average price on the day of delivery to the company falls outside the price range. Payment for the shares shall be made in cash.

Reporting of repurchased shares will be carried out in accordance with applicable rules.

At the time of this press release, the total number of shares in Yubico amounts to 87,291,882, of which 865,000 class C shares are held in treasury by Yubico.
