The board of directors invites the shareholders to attend the annual general meeting to be held on Tuesday May 26, 2026 at 14h00 at Amaryllis Hall at Botanic Sanctuary Antwerp, Leopoldstraat 26 in Antwerp. The shareholders are welcome as of 12h30 to facilitate compliance with the admission formalities for the meeting.

AGENDA

1. Annual report of the board of directors for the financial year ended December 31, 2025
2. Auditor's report for the financial year ended December 31, 2025
3. Approval of the statutory and consolidated annual accounts for the financial year ended December 31, 2025 – Authorisation

Proposed decision: approval of the statutory and consolidated annual accounts for the financial year ended December 31, 2025, including the approval of a gross dividend of 4.60 euros per share.

As treasury shares are not entitled to a dividend, the total amount of the dividend payment will depend on the number of treasury shares held by Ackermans & van Haaren NV and the persons acting in their own name but on its behalf. Determination of May 27, 2026 at 23:59 Belgian time (i.e. the business day before the ex-date) as the relevant time for determining the dividend entitlement and thus the cancellation of dividend rights attached to the treasury shares. Authorisation to the board of directors to insert the final amount of the total dividend payment (and other resulting changes in the profit allocation) in the statutory annual accounts.

1. Discharge of the directors

Proposed decision: granting discharge to the directors for the performance of their mandate during the financial year ending December 31, 2025.

1. Discharge of the statutory auditor

Proposed decision: granting discharge to the statutory auditor for the performance of his mandate during the financial year ending December 31, 2025.

1. Reappointment of directors¹

6.1 Proposed decision: approval of the renewal of the mandate of Menlo Park BV, permanently represented by Mrs Victoria Vandeputte, for a period of four (4) years until the end of the annual general meeting in 2030 and this as an independent director, given that she meets the independence criteria outlined in article 2.3.4 of the company’s Corporate Governance Charter.

6.2 Proposed decision: approval of the renewal of the mandate of Venatio BV, permanently represented by Mr Bart Deckers, for a period of four (4) years until the end of the annual general meeting in 2030 and this as an independent director, given that he meets the independence criteria outlined in article 2.3.4 of the company’s Corporate Governance Charter.

It should be noted that Mr Bart Deckers' spouse is a minority shareholder of Belfimas NV, with no specific representation or blocking rights. The board of directors considers that this situation does not affect Bart Deckers' status as an independent director.

6.3 Proposed decision: approval of the renewal of the mandate of Mr Thierry van Baren as non-executive director for a period of four (4) years until the end of the annual general meeting in 2030.
