1. Authorizing the Board of Directors to decide on the repurchase of the Company's own shares

The Board of Directors proposes to the AGM that the Board of Directors be authorised to decide on the repurchase of the Company's own shares as one or several instalments using non-restricted shareholders' equity, such that the maximum quantity repurchased be 16,200,000 shares. On the date of the notice of meeting, the proposed quantity equals approximately 10 per cent of the total amount of Company's shares. The shares shall be repurchased through public trading organised by Nasdaq Helsinki Ltd in accordance with its rules or using another method. The consideration paid for the shares shall be based on the market price at the time of repurchase.

The authorisation also entitles the Board of Directors to decide on the repurchase of shares in different proportions than the proportion to the shares owned by the shareholders (directed repurchase) with weighty financial reasons. Shares may be repurchased to implement arrangements associated with the share-based incentive systems, remuneration of the Board of Directors or Company's business operations, or to be otherwise transferred or to be cancelled. The repurchased shares can also be held by the Company itself.

The Board of Directors is authorised to make decisions on all other conditions and circumstances pertaining to the repurchase of own shares. The repurchase of own shares reduces the non-restricted shareholders' equity.

The authorisation is proposed to remain valid until the end of the following annual general meeting but in any case, not longer than 30 June 2026. The proposed authorisation shall replace the Company's previous authorisation to repurchase own shares granted by the AGM on 19 June 2024.

1. Authorizing the Board of Directors to decide on the issuance of shares as well as the issuance of options and other special rights entitling to shares, as well as the transfer of own shares

The Board of Directors proposes that the AGM authorise the Board of Directors to decide on the issue of a maximum of 16,200,000 shares through a share issue or by granting options or other special rights entitling to shares as one or several instalments. On the date of the notice of meeting, the proposed quantity equals approximately 10 per cent of the total amount of Company's shares. The authorisation includes the right to issue either new shares or own shares held by the Company, either against payment or without consideration. New shares can be issued and own shares held by the Company transferred in deviation from the shareholders' pre-emptive subscription right (directed issue) if there is a weighty financial reason for the Company to do so and, in case of an issue without consideration, an especially weighty reason for both the Company and in regard to the interests of all shareholders in the Company. The Board of Directors is authorised to decide on all other conditions and circumstances pertaining to a share issue, to the granting of special rights entitling to shares, and to the transfer of shares.

The authorisation may be used, inter alia, to execute Company's share-based incentive systems, to pay the remuneration of the Board of Directors, to strengthen the capital structure, to expand the ownership base, to use as consideration in transactions, or when the Company purchases assets associated with its operations.

The authorisation is proposed to be valid until the end of the following annual general meeting but in any case, no later than 30 June 2026. The authorisation shall replace previous share issue and option authorisations granted by the AGM on 19 June 2024.
