This report includes our report on the annual accounts together with our report on other legal and regulatory requirements. These annual accounts comprise the balance sheet as at 31 December 2016 and the income statement for the year then ended, as well as the summary of accounting policies and other disclosures.

Report on the annual accounts - Unqualified opinion

We have audited the annual accounts of Galapagos NV ("the company") , prepared in accordance with the financial reporting framework applicable in Belgium, which show total assets of 1,139,920 (000) EUR and a loss for the year of 45,228 (000) EUR.

Board of directors' responsibility for the preparation of the annual accounts

The board of directors is responsible for the preparation and fair presentation of annual accounts in accordance with the financial-reporting framework applicable in Belgium, and for such internal control as the board of directors determines is necessary to enable the preparation of annual accounts that are free from material misstatement, whether due to fraud or error.

Statutory auditor's responsibility

Our responsibility is to express an opinion on these annual accounts based on our audit. We conducted our audit in accordance with International Standards on Auditing (ISA). Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the annual accounts are free from material misstatement,

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the annual accounts. The procedures selected depend on the statutory auditor's judgment, including the assessment of the risks of material misstatement of the annual accounts, whether due to fraud or error. In making those risk assessments, the statutory auditor considers internal control relevant to the company's preparation and fair presentation of the annual accounts in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the company's internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by the board of directors, as well as evaluating the overall presentation of the annual accounts. We have obtained from the company's officials and the board of directors the explanations and information necessary for performing our audit.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.
