The report on the remuneration of the governing bodies is available on the company’s website at www.harviagroup.com on 25 March 2026 at the latest.

11. Resolution on the remuneration of the members of the Board of Directors

The Shareholders’ Nomination Board proposes to the Annual General Meeting that the remuneration be paid to the Board members as follows: the Chair of the Board of Directors is paid a monthly remuneration of EUR 5,500 (in 2025: EUR 5,000), Deputy Chair of the Board EUR 4,000 (in 2025: EUR 3,500) and other members of Board of Directors each are paid a monthly remuneration of EUR 3,500 (in 2025: EUR 3,000).

In addition, the Nomination Board proposes that the remuneration of the Board committee members be paid as meeting fees as follows: EUR 1,400 (in 2025: EUR 1,000) per meeting for the chair of the committee and EUR 900 (in 2025: EUR 600) per meeting for the other members.

The proposed increase in remuneration is based on analysis made for the Nomination Board of the total annual remuneration for Board members at comparable Finnish publicly listed companies. Harvia’s aim is to pay competitive remuneration to experienced Board Members proposed by the Nomination Board.

Further, the Nomination Board proposes that the monthly remuneration of the Board members be paid in company shares and in cash in such a way that 40% of the total monthly remuneration will be paid in company shares purchased at a price determined in public trading on Nasdaq Helsinki Ltd or via a share issue and 60% will be paid in cash. The company will pay any trading costs and transfer tax related to the purchase of the remuneration shares. In case the remuneration cannot be paid in the company’s shares due to legal or other regulatory restrictions or due to other reasons related to the company or a member of the Board of Directors or if the payment of the remuneration in shares would prove to be unreasonably difficult in practice, the remuneration will be paid in cash.

The Nomination Board recommends that a member of the Board of Directors does not transfer the shares received as remuneration for Board membership in 2026 until two years have passed since the date of the receipt of the shares.

It is proposed that the remuneration for the Board committee work be paid fully in cash.

In addition, it is proposed that the members of the Board of Directors who live outside Finland be paid a separate meeting fee of EUR 900 for each meeting if the member travels to Finland only for that meeting. It is proposed that the fee be paid in cash. When the member of the Board of Directors attends the meeting by telephone or other electronic means, no such separate fee will be paid for that meeting. No fee is paid for decisions made without convening a meeting.

It is also proposed that the travel expenses of the members of the Board of Directors are compensated in accordance with the company’s travel policy.

12. Resolution on the number of members of the Board of Directors

The Shareholders’ Nomination Board of Harvia Plc proposes to the Annual General Meeting that the number of members of the Board of Directors shall be seven.

The Nomination Board proposes that, should any candidate proposed by the Shareholders’ Nomination Board be prevented from serving, the proposed Board members who are not prevented from serving shall be elected as members of the Board of Directors and the proposed number of Board members shall be decreased accordingly.

13. Election of members of the Board of Directors

The Shareholders’ Nomination Board proposes to the Annual General Meeting that the current members Catharina Stackelberg-Hammarén, Petri Castrén, Anders Holmén, Hille Korhonen, Markus Lengauer and Olli Liitola be re-elected to the Board of Directors for a term beginning at the close of the Annual General Meeting and ending at the close of the next Annual General Meeting. Heiner Olbrich has announced that he is not available for re-election for the next term of the Board of Directors.

In addition, the Nomination Board proposes that Martin Richter be elected as a new member of the Board of Directors.

All proposed persons have given their consent to the appointment. They are independent of the company and of the major shareholders of the company.

The CVs of the current Board members are available at www.harviagroup.com/investor-relations/corporate-governance/harvia-board-of-directors/.

The CV of the proposed new member of the Board of Directors will be made available at https://harviagroup.com/general-meeting/annual-general-meeting-2026/.

The Nomination Board recommends that the Board of Directors would elect Catharina Stackelberg-Hammarén as its Chair and Markus Lengauer as its Deputy Chair.

The task of the Nomination Board is to ensure that the proposed Board of Directors as a whole has sufficient expertise, knowledge and competence and that the composition of the Board of Directors takes into account the independence requirements set out in the Finnish Corporate Governance Code for listed companies and the stock exchange rules that apply to the company. The Nomination Board has assessed that the proposed Board, as a whole, enables effective functioning of the Board and is suitable for the task both collectively and individually, based on their expertise, experience, and other personal qualities.

The Nomination Board’s proposal for the composition of the Board deviates from the recommendation concerning equal representation of women and men in accordance with the Corporate Governance Code, in that two of the members of the proposed seven-member Board are women. According to the aforementioned recommendation, for a seven-member Board of Directors, the minimum representation of the less represented gender is three members.

The Nomination Board has identified the areas of expertise required of member candidates by the company’s business operations and Board work and has made its proposal for the composition taking into account the company’s current and future business development. After thorough consideration, the Nomination Board has concluded that the member candidates and the proposed Board as a whole are best able to meet the requirements set by the company’s business operations and strategic objectives. The recruitment process has been based on areas of expertise confirmed in advance by the Nomination Board, a candidate search conducted by an external expert, and interviews with several female and male member candidates. The identification of areas of expertise and member candidates is carried out annually, and the Nomination Board aims to take into account the balancing of gender distribution in the coming years, while also considering the specific areas of expertise required of candidates.

With regard to the selection procedure for the members of the Board of Directors, the Shareholders’ Nomination Board recommends that shareholders take a position on the proposal as a whole at the General Meeting.

14. Resolution on the remuneration of the auditor

The Board of Directors proposes to the Annual General Meeting that the Auditor to be appointed will receive remuneration in accordance with a reasonable invoice approved by the company.

15. Election of the auditor

The Board of Directors proposes to the Annual General Meeting that Authorised Public Accounting firm Deloitte Oy be elected as the Auditor of the company for the following term of office. Deloitte Oy has stated that Authorised Public Accountant Johan Groop will act as the Responsible Auditor should Deloitte Oy be elected as the Auditor of the company.

16. Resolution on the remuneration of the sustainability reporting assurer

The Board of Directors proposes to the Annual General Meeting that the authorised sustainability auditor to be appointed will receive remuneration in accordance with a reasonable invoice approved by the company.

17. Election of the sustainability reporting assurer

The Board of Directors proposes to the Annual General Meeting that Deloitte Oy be elected as the company’s authorised sustainability auditor for a term that lasts until the end of the company’s next Annual General Meeting. Deloitte Oy has stated that Johan Groop, ASA, APA would act as the responsible authorised sustainability auditor.

In connection with the proposed legislative amendment relating to the directive amending the European Union's sustainability reporting obligations, the sustainability reporting obligations in force on the date of this notice to the Annual General Meeting may no longer apply to the company for the financial year 2026. Therefore, the Board of Directors proposes that the election of the sustainability reporting assurer be made conditional so that the election shall only become effective if the company is, pursuant to the legislation in force at the end of the financial year 2026, obligated to prepare a sustainability report for the financial year 2026 and to obtain assurance thereof.

18. Authorising the Board of Directors to decide on the repurchase of the company’s own shares

The Board of Directors proposes to the Annual General Meeting that the Annual General Meeting authorise the Board of Directors to resolve on the repurchase of a maximum of 934,711 shares in the company in one or several tranches.

The maximum number of shares that can be repurchased corresponds to approximately 5% of all the shares in the company on the date of this notice. However, a decision to acquire own shares shall not be made so that the treasury shares in the possession of the company and its subsidiaries would exceed one tenth of all shares. Only the unrestricted equity of the company can be used to repurchase own shares on the basis of the authorisation. The shares will be repurchased otherwise than in proportion to the shareholdings of the shareholders in public trading arranged by Nasdaq Helsinki Ltd for the market price formed at the moment of purchase or otherwise at a price formed on the market.

The authorisation is proposed to be used e.g., for the purposes of the company’s share-based incentive systems, for the purposes of board compensation or for other purposes decided by the Board of Directors.

Shares purchased by the company may be held by it, cancelled or transferred. The Board of Directors decides on other matters related to the repurchasing of own shares.

The Board of Directors proposes that the authorisation replaces the authorisation of the Board of Directors to resolve on the repurchase of own shares granted by the shareholders of the company on 8 April 2025.

It is proposed that the authorisation remain valid until the closing of the next Annual General Meeting, but no longer than until 30 June 2027.

19. Authorising the Board of Directors to decide on the issue of shares, options and other special rights entitling to shares

The Board of Directors proposes to the Annual General Meeting that the Annual General Meeting authorise the Board of Directors to resolve on the issuance of shares and the issuance of special rights entitling to shares as referred to in Chapter 10 Section 1 of the Finnish Limited Liability Companies Act in one or several parts, either against payment or without payment.

The aggregate number of shares to be issued, including the shares to be received based on special rights, must not exceed 1,869,423 shares. The maximum number of shares to be issued corresponds to approximately 10% of all the shares in the company as at the date of this notice. The Board of Directors may resolve to issue new shares or to transfer own shares possibly held by the company.

The Board of Directors is authorised to decide on all other matters related to the issuance of shares and special rights entitling to shares, including the right to deviate from the pre-emptive right of shareholders to subscribe to shares to be issued. The authorisation is proposed to be used for the purposes of strengthening the balance sheet and financing position of the company, for the purposes of board compensation or for other purposes decided by the Board of Directors.

It is proposed that the authorisation remain valid until the closing of the next Annual General Meeting, but no longer than until 30 June 2027. The authorisation replaces and revokes all previous unused authorisations of the Board of Directors to resolve on the issuance of shares, options and other special rights entitling to shares.
