SCHEDULE 13D

This Amendment No. 1 to Schedule 13D (this 'Schedule 13D/A') amends and supplements the statement on Schedule 13D originally filed with the Securities and Exchange Commission on July 23, 2019 (the 'Schedule 13D') filed by Gilead Sciences, Inc., a Delaware corporation ('Gilead'), and Gilead Therapeutics A1 Unlimited Company, an unlimited liability company formed under the laws of Ireland and a wholly owned subsidiary of Gilead ('A1' and together with Gilead, the 'Reporting Persons'), with respect to the ordinary shares, no par value (the 'Ordinary Shares'), of Galapagos NV (the 'Issuer').

This Schedule 13D/A is being filed to report the closing of an investment in the Issuer pursuant to the previously disclosed Subscription Agreement, dated July 14, 2019, between A1 and the Issuer (the 'Subscription Agreement'). Except as expressly amended by this Schedule 13D/A, the Schedule 13D remains in effect.

Item 1. Security and Issuer.

This Schedule 13D/A amends and supplements the Schedule 13D with respect to the Ordinary Shares of the Issuer. The principal executive offices of the Issuer are located at Generaal De Wittelaan L11 A3, 2800 Mechelen, Belgium.

Item 3. Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and supplemented with the addition of the following:

On August 23, 2019, A1 purchased 6,828,985 Ordinary Shares pursuant to the terms of the Subscription Agreement. The aggregate purchase price for the additional Ordinary Shares purchased pursuant to the Subscription Agreement and disclosed in this Schedule 13D/A was EUR 960,087,001.15.
