The Nomination Committee has convened a total of eight (8) times to prepare its proposal, engaged an international executive search partner for candidate identification and evaluation, and has held discussions with the company's significant shareholders.

The Nomination Committee of Summa Defence Oyj proposes to the Annual General Meeting that the number of Board members be confirmed at six (6).

The Nomination Committee proposes that the following current members continue on the Board:

• Arto Räty
• Sirpa-Helena Sormunen

The following are proposed as new members of the Board of Directors:

• Ville Jaakonsalo
• Ville Heikkinen

Board Remuneration

The Nomination Committee proposes to the Annual General Meeting that the following annual fees be paid to members of the Board of Directors:

• Chair of the Board of Directors: EUR 72,000 per year
• Board member: EUR 36,000 per year
• Chair of the Audit Committee: EUR 15,000 additional fee

Members of any other committees that may be established will be paid a meeting fee of EUR 300 per meeting.

60% of the annual fees would be paid in cash and 40% in shares of Summa Defence Oyj. The share portion would be paid at the beginning of the Board term and the cash portion monthly. No separate meeting fees will be paid.

The proposed remuneration structure has been set at a level that is comparable to board fees at similarly sized Finnish listed companies and takes into account the skills and time commitment expected of board work in the defence sector and in the company's current growth phase. The share component (40%) aligns the financial interests of Board members with those of shareholders. The overall cash impact of the proposal on the company's board remuneration is close to the current level.

The Nomination Committee has assessed the independence of the proposed Board members. The assessment covers both financial and ownership factors as well as any material business relationships with the company. The Nomination Committee considers that all proposed members of the Board of Directors are independent of the company and its significant shareholders.
