9.1 Reappointment of Mr. Kevin Helash, as director of the Company

Taking into account and in accordance with the recommendation and advice of the Nomination and Remuneration Committee, the Board of Directors recommends the reappointment of Mr. Kevin Helash as a director of the Company for an additional term of four years starting immediately after the Shareholders Meeting and which will terminate immediately after the ordinary general meeting to be held in 2029 deciding on the financial statements of the Company for the fiscal year 2028.

Mr. Kevin Helash does not receive a remuneration pursuant to his mandate as director.

Voting instruction:

9.2 Reappointment of Mr. Simon E. Moroney as a non-executive independent director

Voting instruction:

FOR	AGAINST	ABSTENTION

9.3 Reappointment of Mr. Johan Cardoen as a non-executive independent director

Taking into account and in accordance with the recommendation and advice of the Nomination and Remuneration Committee, the Board of Directors recommends the re-appointment of Mr. Johan Cardoen, as a non-executive independent director of the Company for an additional term of four years starting immediately after the Shareholders Meeting and which will terminate immediately after the ordinary general meeting to be held in 2029 deciding on the financial statements of the Company for the fiscal year 2028. With the exception of item 2 of the provision 3.5 of the Belgian Corporate Governance Code 2020 ("not have served for a total term of more than twelve years as a non-executive board member") Mr. Johan Cardoen meets, and has declared to meet, the independence criteria of Article 7:87 of the Belgian Code on Companies and Associations and provision 3.5 of the Belgian Corporate Governance Code 2020. Mr. Johan Cardoen has expressly declared that he does not maintain any relationship with the Company or any major shareholder that would compromise his independence, and the Board of Directors hereby expressly declares that it has no indication of any element that could call into question Mr. Johan Cardoen's independence within the meaning of Article 7:87 of the Belgian Code on Companies and Associations. Regarding point 2 of provision 3.5 of the Belgian Corporate Governance Code 2020 ("not have served for a total term of more than twelve years as a nonexecutive board member"), the Board of Directors mentions that Mr. Johan Cardoen has been a member of the Board of Directors as a non-executive director since 2013 and as an independent director since 2021. However, the Board of Directors believes that there is no reason to question Mr. Johan Cardoen's independence. Mr. Johan Cardoen does not perform any special assignments for the Company or for a major shareholder outside his directorship for which he is

remunerated. Furthermore, Mr. Johan Cardoen has always demonstrated independence and critical thinking in his capacity as director and member of the Research and Development Committee and Mr. Johan Cardoen makes a significant contribution through his scientific knowledge and knowledge of the industry in which the Company operates. The Board of Directors therefore proposes to the general meeting to deviate from the requirement of point 2 of provision 3.5 of the Belgian Corporate Governance Code 2020 and to qualify Mr. Johan Cardoen as a non-executive independent director.

Proposed resolution: On the proposal of the Board of Directors, in accordance with the recommendation and advice of the Nomination and Remuneration Committee, the general meeting resolves (a) to reappoint Mr. Johan Cardoen with address 9255 Buggenhout (Belgium), Ten Hove 16 as a non-executive independent director of the Company, for a term of four years starting immediately after this shareholders meeting and which will terminate immediately after the ordinary general meeting to be held in 2029 deciding on the financial statements of the Company for the fiscal year 2028, and (b) to confirm his mandate in his capacity as an independent member of the Board of Directors in that (i) Mr. Johan Cardoen meets, and has declared to meet, the independence criteria of Article 7:87 of the Belgian Code on Companies and Associations and provision 3.5 (except for point 2 thereof) of the Belgian Corporate Governance Code 2020, (ii) Mr. Johan Cardoen has expressly declared that he does not maintain any relationship with the Company or any major shareholder that would compromise his independence, and (iii) the Board of Directors has expressly stated that it has no indication of any element that could call Mr. Johan Cardoen's independence within the meaning of Article 7:87 of the Belgian Code on Companies and Associations, into question. The general meeting also decides to deviate from point 2 of provision 3.5 of the Belgian Code on Corporate Governance 2020 and to confirm the independence of Mr. Johan Cardoen notwithstanding the fact that through the reappointment Mr. Johan Cardoen will hold a mandate as a non-executive director for more than 12 years based on the argumentation of the Board of Directors that (i) Mr. Johan Cardoen does not perform any special assignments for the Company or for a major shareholder outside his directorship for which he is remunerated, (ii) Mr. Johan Cardoen has always demonstrated independence and critical thinking in his capacity as a director of the Company and member of the Research and Development Committee and (iii) Mr. Johan Cardoen makes a significant contribution through his scientific knowledge and knowledge of the industry in which the Company operates. The general meeting resolves that the mandate of Mr. Johan Cardoen be remunerated as provided for non-executive independent members of the Board of Directors in the Company's remuneration policy and as approved by the general meeting from time to time.
