About the Board of Directors

Galapagos NV’s Board of Directors consists of at least five and no more than nine members. At least three members of our Board of Directors are independent. On December 31, 2025, the Board of Directors consisted of eight members, four of whom are independent within the meaning of article 7:87 of the BCCA and provision 3.5 of the 2020 Code, or 50%.

Except for Henry Gosebruch, all members of the Board of Directors are Non-Executive Directors.

The members of our Board of Directors are appointed by the Shareholders’ Meeting upon the proposal of the Board of Directors, for a renewable term of up to four years. Members of the Board of Directors whose mandate has come to an end may be re-appointed. When a position on the Board of Directors becomes vacant, the remaining members may temporarily fill the mandate by co-optation until appointment of a new Board member at the next shareholders’ meeting. Each member of the Board of Directors appointed as such by the Shareholders’ Meeting shall complete the tenure of the member of the Board of Directors he/she replaces, unless the Shareholders’ Meeting decides otherwise. The Nomination Committee nominates, for approval by the Board of Directors, candidates to fill vacancies as they arise, and advises on proposals for appointments originating from shareholders, in each case taking into account the Company’s needs and the selection criteria determined by the Board of Directors. In proposing candidates, particular consideration is given to gender diversity and diversity in general, as well as complementary skills, knowledge and experience.

Provision 3.12 of the 2020 Code recommends that, in case of a one-tier governance structure, (a) there should be a clear division of responsibilities between the person presiding over the Board of Directors (the Chair) and the person assuming executive responsibility for running the Company’s business (the CEO), and (b) the Chair of the Board of Directors and the CEO should not be the same individual. In deviation from this provision, Stoffels IMC BV (permanently represented by Dr. Paul Stoffels), who was our CEO from April 1, 2022 until May 12, 2025, was also appointed as Chair of the Board of Directors on of April 26, 2022 and served in that role until May 12, 2025. In light of the prevailing circumstances, the Board of Directors considered that the one-tier governance structure and the combined role as CEO/Chair allowed the Company to fully leverage the leadership of Dr. Paul Stoffels, and to efficiently set and implement the Company’s direction and strategy. Furthermore, the Board of Directors was of the opinion that such combined role had a positive impact on the functioning and efficiency of the Board, as well as on the provision of information to the Board of Directors, allowing the Board to monitor the Company’s (and the Galapagos group’s) performance more effectively during the first half of 2025. In order to ensure a sufficient balance, the Board adopted a counter balancing governance structure that included the election of a Lead Non-Executive Director acting as the principal liaison between the Chair and the Non-Executive members of the Board of Directors (see also below). Effective as of March 21, 2023 and until May 12, 2025, Jérôme Contamine was appointed as Lead Non-Executive Director of the Company. The Lead Non-Executive Director was entrusted with the responsibilities and powers set out in the Corporate Governance Charter of Galapagos NV. Effective May 12, 2025, Stoffels IMC BV stepped down as CEO and Chair, and Jérôme Contamine succeeded Stoffels IMC BV as Chair.

The following table sets forth certain information with respect to the members of our Board of Directors during the financial year ended on December 31, 2025:

On December 31, 2025, the Board of Directors thus consisted of three women, or 37.5%, and five men, or 62.5%, representing different nationalities and age categories.

During 2025, we complied with our obligations with respect to gender diversification in the Board of Directors as set forth in article 7:86 of the BCCA, and the Board of Directors will continue to monitor future compliance. In proposing candidates, particular consideration is given to diversity in gender, age, nationality, educational and professional background, as well as complementary skills, knowledge and experience. The profiles of all members of the Board of Directors per December 31, 2025 are included in this report (see above) and the profiles of all members of the Board of Directors at the date of the publication of this report are also available on www.glpg.com.

The below charts show the status per December 31, 2025:

The role of the Board of Directors is to pursue the long-term success of and sustainable value creation by Galapagos NV. The Board of Directors does so by assuming the authority and responsibilities assigned to it under applicable laws and regulations (including, without limitation, the BCCA and the 2020 Code) and the Articles of Association, and by combining entrepreneurial leadership with appropriate risk assessment and management. Each of the Directors’ expertise and experience is exemplified by the varied professional activities they carry out and offices they hold. During its meetings in 2025, the Board of Directors dealt with matters pertaining to, among other things, the intended separation of the Company as announced on January 8, 2025 and the discontinuation of the small molecules research activities, the evaluation of business development projects, the convening of the 2025 AGM and preparation of resolutions to be submitted for approval to the shareholders, strategy and value creation, the strategic alternatives process for cell therapy activities, the intention to wind down cell-therapy activities, the amendment of our collaboration with Gilead, the search and recruitment of new Directors and Officers, the review of clinical trial results, the creation of advisory Board Committees and related update of our Corporate Governance Charter, and the review and approval of our financial and non-financial reporting.

In 2025, twenty-three meetings of the Board of Directors took place physically, through written resolutions or calls to discuss specific matters, including two meetings in the presence of a notary public (relating to the issuance of Subscription Right Plan 2025 (A) and Subscription Right Plan 2025 (B)). The first meeting in the presence of a notary public was attended by Jérôme Contamine and Peter Guenter. All other Directors, except for Henry Gosebruch, were represented by proxy at the Board meeting in the presence of a notary public. The second meeting in the presence of a notary public was attended by Jérôme Contamine and Elisabeth Svanberg. All other Directors were represented by proxy at the Board meeting in the presence of a notary public. Except for the meetings in the presence of a notary public, the overall attendance rate for Board meetings was 99%. In 2025, Stoffels IMC BV (permanently represented by Dr. Paul Stoffels), Andrew Dickinson, Linda Higgins, Peter Guenter, and Henry Gosebruch recused themselves from deliberation and decision-making on a number of agenda items due to conflicts of interest, in accordance with article 7:96 of the BCCA, as set forth in further detail in the section titled Conflicts of interest and related parties. This was not considered when assessing overall attendance.

The Board of Directors acts as a collegial body.

Provision 9.1 of the 2020 Code recommends that the Board of Directors assess its own performance and its interaction with the executive management, as well as its size, composition, functioning and that of its committees at least every three years. An evaluation of the Board of Directors and its Board Committees was carried out in the second half of 2022. As part of this exercise, the Board of Directors’ composition was reviewed, a composition matrix was created, and interviews were held with Board members on the functioning and composition of the Board of Directors. Board member profiles were established, which served the Board in the search for Director candidates to fill open positions by co-optation. In light of the Company’s ongoing transformation and the appointment by way of co-optation of several new Directors in 2025, the Board concluded that conducting an evaluation during 2025 would have been premature. The Board expects to undertake an evaluation in 2026.

Pursuant to the Company’s Corporate Governance Charter and as a counter balancing governance structure for the combined CEO and Chair role within the Board (until May 12, 2025), the Board of Directors had appointed a Lead Non-Executive Director. The Lead Non-Executive Director is also automatically the Vice-Chair of the Board of Directors. The Lead Non-Executive Director is entrusted with the responsibilities and powers set out in Galapagos NV’s Corporate Governance Charter, including, but not limited to, serving as principal liaison between the Non-Executive Directors and the Chair of the Board. Effective as of March 21, 2023 and until May 12, 2025, Jérôme Contamine was appointed as the Lead Non-Executive Director of Galapagos NV.

The Board of Directors has appointed a Secretary entrusted with the functions set out in Galapagos NV’s Corporate Governance Charter, including, but not limited to, advising the Board of Directors and its individual members on all corporate governance matters.
