Severance Payments

On April 15, 2025, Galapagos announced the departure of Mr. Thad Huston, CFO and COO and Executive Committee member, effective August 1, 2025. Upon recommendation of the Remuneration Committee, the Board approved a termination compensation of €153,125, which takes into account a severance compensation and legal fees. The Board determined this arrangement would best serve the interests of Galapagos, in particular as it ensured Mr. Huston’s continued support for specific business operations and an orderly transition of his responsibilities. Effective July 31, 2025, Mr. Huston was no longer a member of the Executive Committee. He did not receive any equity grants (RSUs and subscription rights) in 2025. He qualifies as a good leaver under the terms and conditions of the Subscription Right Plan 2023 BE with respect to his sign-on subscription rights, which were issued as a replacement for lapsed equity with a previous employer and were not part of his termination package. Any and all other subscription rights granted by Galapagos lapsed upon his end date.

On May 13, 2025, Galapagos announced the appointment of Mr. Henry Gosebruch by Galapagos’ Board of Directors as CEO of Galapagos, effective as of May 12, 2025 (23:59 CET), succeeding Stoffels IMC BV, permanently represented by Dr. Paul Stoffels. Effective May 12, 2025, Stoffels IMC BV was no longer a member of the Executive Committee. Upon recommendation of the Remuneration Committee, the Board approved a retirement compensation of €539,500, which takes into account a severance compensation. He remains available to Galapagos under a consulting agreement until date May 2, 2026, and during this period, he remains entitled to RSU vestings and pay-outs. The Board determined that this arrangement would best serve the interests of Galapagos, in particular given his knowledge of the cell therapy business and its relevance to the strategic alternatives exercise. Stoffels IMC BV did not receive any equity grants (RSUs and subscription rights) in 2025. He qualifies as a good leaver under the terms and conditions of the relevant subscription right plans, which are not part of his termination package.

On October 16, 2025, Galapagos announced the departure of Ms. Valeria Cnossen, General Counsel and Executive Committee member. Upon recommendation of the Remuneration Committee, the Board approved a termination compensation of €653,445, which takes into account a severance compensation in lieu of notice period, legal fees, and the loss of certain unvested RSUs, excluding the continued use of the leased car for two months. Effective October 16, 2025, Valeria Cnossen was no longer a member of the Executive Committee. The Board determined this arrangement would best serve the interests of Galapagos. Ms. Cnossen did not receive any subscription rights in 2025 and the details of her 2025 RSU grant are set forth in the section“Further Information on Equity-Based Remuneration”. She qualifies as a good leaver under the terms and conditions of the relevant subscription right plans, which are not part of her termination package.

On February 23, 2026, Galapagos announced the end of Mrs. Annelies Missotten’s mandate as member of the Executive Committee, effective December 31, 2025. She will continue to serve as a full-time consultant. Upon recommendation of the Remuneration Committee, the Board approved a termination compensation of €173,750, which takes into account a severance compensation in lieu of notice period. Ms. Missotten agreed to serve as a full-time consultant until June 30, 2026, for a total consultancy fee of €225,587 (excluding VAT) which is comparable to what her compensation as CHRO would have been. In addition, bonus arrangements will apply while Ms Missotten serves as a full-time consultant. The Board determined this arrangement would best serve the interests of Galapagos, in particular given the critical role played by the outgoing CHRO in supporting the wind-down of the cell therapy business, leading the 2025 compensation cycle, and ensuring business continuity as a successor is onboarded. Annelies Missotten did not receive subscription rights in 2025 and the details of her 2025 RSU grant are set forth in the section “Further Information on Equity-Based Remuneration”. She qualifies as a good leaver under the terms and conditions of the relevant subscription right plans, which are not part of her termination package. There was no contract termination cost for Annelies Missotten accounted for in our 2025 consolidated financial statements. The severance and agreed compensation will be expensed in the first half of 2026.
