Events after the end of the reporting period

On 19 April 2018, the board of directors of Galapagos approved the “Warrant Plan 2018,” a warrant plan intended mainly for certain (future) employees of the company and its subsidiaries, and also for directors and an independent consultant of the company, and the “Warrant Plan 2018 RMV,” a warrant plan intended for certain employees of its French subsidiary, Galapagos SASU, within the framework of the authorized capital. Under these warrant plans, 1,585,000 warrants were created, subject to acceptances, and offered to the beneficiaries of the plans. The warrants have an exercise term of eight years as of the date of the offer and have an exercise price of €79.88 (the average closing price of the share on Euronext Amsterdam and Brussels during the thirty days preceding the date of the offer). The warrants are not transferable and can in principle not be exercised prior to 1 January 2022. Each warrant gives the right to subscribe to one new Galapagos share.
