Events after the end of the reporting period

On 10 April 2019, the board of directors of Galapagos approved “Warrant Plan 2019,” a warrant plan intended mainly for the employees of the company and its subsidiaries, and also for directors and an independent consultant of the company, and “Warrant Plan 2019 RMV,” a warrant plan intended for the employees of its French subsidiary, Galapagos SASU, within the framework of the authorized capital. Under these warrant plans, 2,070,000 warrants were created, subject to acceptances, and offered to the beneficiaries of the plans. The offer of warrants to directors remains subject to approval of the annual shareholders’ meeting of 30 April 2019. The warrants have an exercise term of eight years as of the date of the offer and have an exercise price of €95.11 (the average closing price of the share on Euronext Amsterdam and Brussels during the thirty days preceding the date of the offer). In principle, the warrants are not transferable and cannot be exercised prior to 1 January 2023. Each warrant gives the right to subscribe to one new Galapagos share.
