Former Chair of the Board of Directors of Metsä Board Corporation ("Metsä Board" or the "Company"), Mr. Ilkka Hämälä, has resigned from his duties on the Board of Directors effective 1 July 2025 in accordance with the stock exchange release given on 12 June 2025. Pursuant to the resolution of the Annual General Meeting of Metsä Board held on 20 March 2025, a portion of Mr. Hämälä's annual remuneration was provided in Metsä Board's B shares on 30 April 2025. Following the resignation of Mr. Hämälä, the Company has today received from him, without consideration, a total of 10,738 B shares, which had previously been acquired to him as annual remuneration. The received amount of shares corresponds to approximately 8.5 months of the Board term that was not realised, and the paid remuneration has therefore been adjusted to reflect the actual term served by Mr. Hämälä.

Following the return of these shares, the Company holds a total of 352,444 of its own B shares.

On 31 July 2025, Metsä Board announced that Erja Hyrsky would step down from the Company's Board of Directors with immediate effect following her appointment as SVP, Commercial Operations as of 1 August 2025. It was also agreed with Hyrsky that her annual remuneration would be proportionally adjusted to reflect the actual term served on the Board of Directors, which amounted to approximately 4.5 months. However, the portion of the annual remuneration subject to return has been incorporated into her overall compensation as an employee of Metsä Board, and therefore the total number of shares held by the Company remains unchanged.
