Letter from the management

Dear shareholders,

We present you with our report on the first quarter of 2021, one in which we both delivered progress with and faced adversity in our pipeline, while driving our commercial business in Europe through the launch of Jyseleca (filgotinib) in rheumatoid arthritis (RA). We move forward with confidence at Galapagos, applying lessons learned to our pipeline decisions, and re-fitting our organization to the new situation.

In February, we announced the end of the development program for ziritaxestat, a molecule in Phase 3 trials in idiopathic pulmonary fibrosis (IPF), due to the unfavorable risk/benefit profile observed by an Independent Data Monitoring Committee (IDMC). As disappointed as we were, and for patients in need of a new treatment option in this very complex, debilitating condition, we continue to work hard on our differentiated pipeline.

These last months, we embarked on a review of our plans. We listened to our shareholders and had constructive discussions with our R&D teams and management board members, as well as with our supervisory board. We all agree that our scientific foundations are solid, we have outstanding teams, and we have the financial resources to execute our own programs as well as to enrich our pipeline.

Onno van de Stolpe, CEO Bart Filius, President & COO

We do not intend to deviate from our mission to build on novel targets to address unmet medical needs in inflammation, fibrosis, and kidney disease. Also, we remain fully committed to the launch of filgotinib in Europe. Our teams are working very hard to ensure our drug reaches the greatest number of patients and we've already hit some important milestones in RA. Furthermore, Gilead submitted the new drug application in Japan for filgotinib for the treatment of ulcerative colitis (UC) patients with an inadequate response to conventional therapies, and, in Europe, we anticipate a Committee for Medicinal Products for Human Use (CHMP) opinion on the submission for potential approval in UC later this year.

The key objective of our exercise was to refocus development plans for 2021, taking lessons learned on board and right-sizing our organization with the goal to select a more risk-balanced pipeline.

In the end we made three key decisions:

    1. Refocus our clinical pipeline by critically examining its risk profile and breadth;
    1. Cut significant cost in the organization to support this re-sized pipeline development; and
    1. Task our business development team to identify and execute on a transformative opportunity.

Starting with our pipeline, we carefully evaluated the risk-balance and prioritized assets with what we believe have enhanced chances of clinical success in our core therapeutic areas:

  • We are testing our lead Toledo program '3970, a SIK2/3 inhibitor, in five Proof of Concept studies in different indications, and pending on the outcome of the studies, we plan to roll out our further development plans in the second half of the year;
  • We selected an additional molecule from our Toledo program, SIK2/3 inhibitor '4876, as a candidate to accelerate from preclinical phase into clinical development;
  • We aim to progress our TYK2 inhibitor '3667 into Phase 2b;
  • We selected chitinase inhibitor '4617 to progress to Phase 2 in IPF and decided to stop development of our other IPF molecule '1205;
  • We stopped further work on '4059 for metabolic disease, given that this is not a core therapeutic area;
  • We discontinued our early research efforts in metabolic diseases and osteoarthritis (OA); and
  • We challenged and fine-tuned our stage-gating process to advance compounds.

Our reviewed pipeline offers significant newsflow and we look forward to sharing results this year and next.

In line with our review, we decided to discontinue or cancel certain studies, and we identified opportunities to reduce operational costs, for a total potential savings of €150 million on a full-year basis. Roughly half of these savings will be realized in 2021, resulting in a 2021 cash burn guidance of between €580 million and €620 million.

Meanwhile, we remain well on track in launching filgotinib in Europe. In the first quarter, we successfully completed the transitions of commercial and medical teams from Gilead in Germany, the UK, Spain, and Italy. Everything is in place to complete the final transitions from Gilead to us by year-end. Q1 also saw progress on access and reimbursement for filgotinib in RA. We are delighted with the recommendation by the National Institute for Health and Care Excellence (NICE) for filgotinib in the UK for the treatment of eligible adult patients with moderate to severe active RA. Furthermore, we received an additional benefit in RA by the Gemeinsamer Bundesausschuss (G-BA) in Germany. We are encouraged by the primary endpoint outcome with the MANTA/RAy semen parameter studies as we await the CHMP opinion in UC.

We are pleased that our partner Gilead recently announced an extension of the lockup period for their current holding in Galapagos (16,707,477 shares) until 2024, which is testament to their continued support.

Altogether, these adjustments make for a right-sized, refocused version of Galapagos, on a path towards success with our first commercial product as well as with new R&D opportunities, substantial clinical news flow, and a lengthened cash runway for clinical validation of our early assets.

Operational overview Q1 2021

In inflammation

  • We and Gilead announced interim data on the MANTA/RAy studies. 8.3% of patients on placebo and 6.7% of patients on filgotinib had a 50% or more decline in sperm concentration at week 13; these results are being shared with regulatory authorities
  • We initiated two additional Proof of Concept trials with Toledo compound '3970, a SIK2/3 inhibitor. The first patients were dosed in both the TAPINOMA study in systemic lupus erythematosus and in the GLIDER study in Sjögren's syndrome
  • Gilead announced that NICE recommended filgotinib for reimbursement for moderate to severe RA patients in the UK
  • We published the FINCH 1 Phase 3 data (Combe et al. 2021) and FINCH 3 Phase 3 data (Westhovens et al. 2021) in the Annals of the Rheumatic Diseases

In fibrosis

▪ We discontinued development of ziritaxestat in the ISABELA Phase 3 program in IPF

Corporate & other

  • Bart Filius was promoted to President and Chief Operating Officer
  • We raised €2.3 million from subscription right exercises

Recent events

  • All annual general meeting (AGM) proposals were approved by shareholders at the AGM on 28 April 2021
  • We received a transparency notification from the Capital Group indicating they hold 4.65% of the current outstanding Galapagos shares
  • Gilead submitted the new drug application in Japan for filgotinib for the treatment of UC with an inadequate response to conventional therapies
  • We and Gilead ended the DIVERGENCE 2 trial with filgotinib in fistulizing CD
  • We completed enrollment of the SEA TURTLE Phase 2 study with '3970 in UC
  • We announced an extension of the lockup period for Gilead's current shares in Galapagos to 2024
  • We received the second installment of €75 million from Gilead, following payment of an earlier installment of €35 million in January 2021, included under the revised filgotinib agreement as announced in December 2020

Q1 2021 financial result

Details of financial results

Due to the sale of our fee-for-service business (Fidelta) to Selvita on 4 January 2021 for a total consideration of €37.1 million (including customary adjustments for net cash and working capital), the results of Fidelta are presented as "Net profit from discontinued operations" in our consolidated income statements.

Revenues and other income from continuing operations

Our revenues and other income from continuing operations for the first three months of 2021 amounted to €124.2 million, compared to €103.6 million for the first three months of 2020.

Revenues amounted to €113.9 million for the first three months of 2021 compared to €94.8 million for the first three months of 2020, and were higher mainly driven by the increase in revenue recognition of upfront consideration and milestone payments received in the scope of the collaboration with Gilead for filgotinib amounting to €55.3 million for the first three months of 2021 (€35.4 million for the same period last year).

Other income (€10.3 million vs €8.7 million for the same period last year) increased, mainly driven by higher incentives income from the government for our R&D activities.

Results from continuing operations

We realized a net loss from continuing operations of €12.8 million for the first three months of 2021, compared to a net loss of €52.3 million for the first three months of 2020.

We reported an operating loss amounting to €50.8 million for the first three months of 2021, compared to an operating loss of €46.2 million for the same period last year.

Our R&D expenditure in the first three months of 2021 amounted to €130.0 million, compared to €115.5 million for the first three months of 2020. This increase was due to an increase in subcontracting costs primarily related to our filgotinib program, our Toledo program and other clinical programs, compensated by a decrease for ziritaxestat, the OA program with GLPG1972 and the program in atopic dermatitis (AtD) with MOR106. Furthermore, personnel costs increased explained by a planned headcount increase following the growth of our activities and increased cost of our subscription right plans. This last factor, together with increased costs of the commercial launch of filgotinib in Europe, contributed to the increase in our G&A and S&M expenses which were €45.0 million in the first three months of 2021, compared to €34.3 million in the first three months of 2020.

We reported a non-cash fair value gain from the re-measurement of initial warrant B issued to Gilead, amounting to €2.0 million, mainly due to the decreased implied volatility of the Galapagos share price as well as its evolution between 31 December 2020 and 31 March 2021.

Net other financial income in the first three months of 2021 amounted to €36.2 million, compared to net other financial income of €14.8 million for the first three months of 2020, which was primarily attributable to €45.5 million of currency exchange gain on our cash and cash equivalents and current financial investments in U.S. dollars and to €6.5 million of negative changes in (fair) value of current financial investments and financial assets.

Results from discontinued operations

The net profit from discontinued operations for the three months ended 31 March 2021 consisted of the gain on the sale of Fidelta, our fee-for-services business, for €22.2 million.

Group net results

The group realized a net profit for the first three months of 2021 amounting to €9.4 million, compared to a net loss of €50.6 million for the same period in 2020.

Cash position

Current financial investments and cash and cash equivalents totaled €5,114.7 million on 31 March 2021 (€5,169.3 million on 31 December 2020, including the cash and cash equivalents included in the assets classified as held for sale).

Total net decrease in current financial investments and cash and cash equivalents amounted to €54.6 million in the first three months of 2021, compared to a net decrease of €58.4 million during the first three months of 2020. This net decrease was composed of (i) €127.7 million of operational cash burn,1 (ii) offset by €2.3 million of cash proceeds from capital and share premium increase from exercise of subscription rights in the first three months of 2021, (iii) €3.6 million of negative changes in (fair) value of current financial investments and €45.7 million of mainly positive exchange rate differences, (iv) €28.7 million cash in from the disposal of Fidelta, net of cash disposed.

Finally, our balance sheet on 31 March 2021 held a receivable from the French government (Crédit d'Impôt Recherche 2 ) and a receivable from the Belgian Government for R&D incentives, for a total of €142.3 million.

Outlook 2021

We anticipate regulatory announcements with filgotinib as well as news on progress in our differentiated pipeline of novel target-based candidates this year.

We expect reimbursement decisions in most key European markets for filgotinib in RA this year, as we complete the transition to a full European commercial operation by year end. We anticipate a CHMP opinion and a European Commission decision for filgotinib in UC. We expect that our collaboration partner Gilead will complete recruitment for the global DIVERSITY Phase 3 trial in Crohn's disease this year.

Within our broader inflammation portfolio, we expect to report topline results from several trials this year, including a Phase 1b trial with TYK2 inhibitor '3667 in psoriasis and three Proof of Concept studies with lead Toledo candidate SIK2/3 inhibitor '3970 in psoriasis, UC, and RA.

Within our fibrosis portfolio, we expect to progress early clinical compounds with novel mechanisms of action, with the aim to develop novel treatments to help patients suffering from this debilitating condition.

Following the review of our plans for 2021, we give guidance for full year 2021 operational cash burn of €580 to €620 million, and potential savings of €150 million on a full-year basis.

We thank you for your continued support, as we move forward on our strategy to develop novel mechanism of action drugs aimed at addressing unmet need in inflammation, fibrosis, and kidney disease. We are confident that we have a strong cash position, expert teams, and excellent science to achieve this.

COVID-19 impact

During the COVID-19 pandemic, we continue to innovate to accommodate for the current situation and minimize the impact to operations. We closely follow local governmental measures and apply these as appropriate within our organization, guided and supported by our dedicated COVID-19 task force teams. All local and global task force teams meet regularly and make recommendations directly to the COO.

We report the following impacts:

▪ Staff

We implemented strict measures to help prevent the spread of the virus and protect the health of our staff. We rolled out our global and site-specific business continuity plans and took appropriate recommended precautions, including suspending almost all business travel. We continue to believe that during the pandemic most of the international travel can be replaced by virtual meetings, resulting in improved cost efficiency, a better work-life balance, and a reduced carbon footprint. The positive impact of this forced wayof-working will therefore be retained in our future habits and updated work place strategy, called "To the Next Normal."

During lock-down periods, we arranged for essential tasks to be carried out within our facilities. Employees working on site need an authorization letter signed by the line leader and site head. Consequently, the majority of our Research staff continue working from the offices/labs, with periodic exceptions for local lockdowns during which no staff is allowed to come into the facilities. For those employees coming to the office, we have stringent cleaning and sanitation protocols in place, and we strictly respect social distancing policies at all times in order to minimize risk of exposure. Except for employees with laboratory operations and safety roles which require an on-site presence, over 95% of our staff systematically work from home.

As the global pandemic continues into 2021, we anticipate that we will maintain our measures and protocols to ensure the health of our employees.

▪ Research portfolio

By prioritizing the most advanced projects very early on, increasing the flexibility of our staff in the labs within projects, and maintaining our hiring efforts and outscourcing as planned, we sustain our research delivery, keep the compound management facility running at all times, and continue our early drug research and the implementation of new modalities for target or drug discovery.

So far, the scorecard of the research department objectives shows a similar productivity compared to previous years, indicating that we continue to minimize the impact of the pandemic.

▪ Development portfolio

We have a business continuity plan for our clinical development programs. We closely monitor each program in the context of the current global and local situation of the pandemic and the associated specific regulatory, institutional, and government guidance and policies related to COVID-19. Within the boundaries of these guidances and policies, and in consultation with our CROs and clinical trial sites, we applied various measures to minimize the impact of the COVID-19 pandemic on our clinical development programs, with the primary aim to ensure the safety of our trial participants and to preserve the data integrity and scientific validity of the trials. These measures continue to be implemented on a case-by-case basis, tailored to the specific study and country needs at any given time, with specific attention paid to vulnerable populations and the use of investigational medicines with immunosuppressive properties. The measures include, among others, increased, transparent communication to all stakeholders and the direct supply of investigational medicines to patients. For each clinical trial, we actively monitor and document the impact of COVID-19 on the study where necessary and to facilitate the interpretation and reporting of results.

Following the global increase of COVID-19 testing and vaccinations, we issued an internal guidance on the impact of testing and vaccinations on clinical trials.

▪ Filgotinib filing process UC

As of publication of this Q1 report, our collaboration partner Gilead has not been informed by the regulatory agencies in Europe of approval timeline delays related to the pandemic.

▪ Manufacturing and supply chain

To date, there has been no COVID-19 impact to the commercial supply of filgotinib. Gilead also confirmed that all sites involved in the manufacturing of filgotinib are established sites that currently manufacture other Gilead marketed products and are in good standing with the FDA and are GMP certified. Under the revised agreement with Gilead for filgotinib in Europe, Galapagos plans to become the marketing authorization holder of filgotinib in Europe by year-end 2021, and then become responsible for manufacturing. We intend to work with the same manufacturing sites to ensure continuity.

▪ Commercial organization

The form of outreach of our commercial teams to physicians and hospitals was impacted by the COVID-19 pandemic and consequent travel restrictions, becoming virtual instead. The teams invested in virtual channels as part of the overall commercial build strategy, and these channels are being utilized during our commercial launch today. We note as of now no material impact on our commercial operations due to travel restrictions, nor has there been an impact of COVID-19 on our ability to engage in market access discussions thus far. Nevertheless, healthcare systems are under pressure across Europe, increasing the risk of future volatility in reimbursement procedures and potentially reducing the number of new therapy initiations.

Notes to the unaudited condensed consolidated interim financial statements for the first three months of 2021

Basis of preparation

These condensed consolidated interim financial statements have been prepared in accordance with IAS 34 'Interim Financial Reporting' as adopted by the European Union and as issued by the IASB. The condensed consolidated interim financial statements do not contain all information required for an annual report and should therefore be read in conjunction with our Annual Report 2020.

The condensed consolidated interim financial statements were subject to a review by the statutory auditor, but have not been audited.

Impact of COVID-19 on the financial statements

To date, we have experienced limited impact on our financial performance, financial position, cash flows and significant judgements and estimates, although we continue to face additional risks and challenges associated with the impact of the outbreak.

We refer to the section Covid-19 impact in this Q1 report for a comprehensive overview of the impact of Covid-19 on the business evolution of Galapagos.

Significant accounting policies

There were no significant changes in accounting policies applied by us in these condensed consolidated interim financial statements compared to those used in the most recent annual consolidated financial statements of 31 December 2020.

New standards and interpretations applicable for the annual period beginning on 1 January 2021 did not have any impact on our condensed consolidated interim financial statements.

We have not early adopted any other standard, interpretation, or amendment that has been issued but is not yet effective.

Revenues and other income

Revenues

The following table summarizes our revenues for the three months ended 31 March 2021 and 2020.

Three months ended 31 March

Total revenues 113,892 94,817

Revenues (€113.9 million for the first three months of 2021, compared to €94.8 million for the first three months of 2020) were higher mainly driven by the increase in revenue recognition of upfront consideration and milestone payments received in the scope of the collaboration with Gilead for filgotinib amounting to €55.3 million for the first three months of 2021 (€35.4 million for the same period last year). The increased cost share and the additional upfront consideration as a consequence of the renegotiated arrangement between Gilead and Galapagos in December 2020, as well as the milestones for the approval of filgotinib in Europe and Japan achieved in the third quarter of 2020, all contributed to this increase in revenues.

FINANCIAL STATEMENTS

The rollforward of the outstanding balance of the current and non-current deferred income between 1 January 2021 and 31 March 2021 can be summarized as follows:

(1) The outstanding balance at 31 March 2021 and at 31 December 2020 comprises the issuance liability for the subsequent warrant B and the upfront payment allocated to the drug discovery platform.

(2) With regard to the additional consideration received for the extended cost sharing for filgotinib, we assume the existence of a significant financing component reflecting the time value of money on the estimated recognition period.

Other income

Other income (€10.3 million for the first three months of 2021, compared to €8.7 million for the first three months of 2020) increased by €1.6 million, mainly driven by higher incentives income from the government for R&D activities.

Results from continuing operations

We realized a net loss from continuing operations of €12.8 million for the first three months of 2021, compared to a net loss of €52.3 million in the first three months of 2020.

We reported an operating loss amounting to €50.8 million for the first three months of 2021, compared to an operating loss of €46.2 million for the same period last year.

Our R&D expenditure in the first three months of 2021 amounted to €130.0 million, compared to €115.5 million in the first three months of 2020. This increase was due to an increase of €3.4 million in subcontracting costs primarily related to our filgotinib program, our Toledo program and other clinical programs, compensated by a decrease for ziritaxestat, the OA program with GLPG1972 and the AtD program with MOR106. Furthermore, personnel costs increased by €10.1 million from €30.3 million in the first three months of 2020 to €40.4 million in the first three months of 2021. This increase is explained by a planned headcount increase and increased costs of the subscription right plans.

FINANCIAL STATEMENTS

The table below summarizes our R&D expenditure for the three months ended 31 March 2021 and 2020, broken down by program.

Three months ended 31 March
(thousands of €) 2021 2020
Filgotinib program (36,932) (29,296)
Ziritaxestat program (10,513) (13,783)
OA program with GLPG1972 (636) (6,427)
Toledo program (27,823) (16,871)
AtD program with MOR106 (152) (4,248)
Other programs (53,904) (44,828)
Total research and development expenditure (129,960) (115,453)

Our G&A and S&M expenses were €45.0 million in the first three months of 2021, compared to €34.3 million in the first three months of 2020. This increase mainly resulted from higher personnel costs for €9.6 million (€26.5 million in the first three months of 2021 compared to €16.9 million in the same period last year). This increase was due to a planned headcount increase following the commercial launch of filgotinib in Europe as well as higher costs of the subscription right plans.

In the first three months of 2021, we reported a non-cash fair value gain from the re-measurement of initial warrant B issued to Gilead, amounting to €2.0 million, mainly due to the decreased implied volatility of the Galapagos share price as well as its evolution between 31 December 2020 and 31 March 2021.

Net other financial income in the first three months of 2021 amounted to €36.2 million (as compared to €14.8 million in the same period last year), which was primarily attributable to €45.5 million of currency exchange gains on our cash and cash equivalents and current financial investments in U.S. dollars (as compared to €34.3 million in the first three months of 2020) and €3.6 million negative changes in (fair) value of current financial investments (€14.5 million in the same period last year). The other financial expenses also contained the effect of discounting our long term deferred income for €2.4 million (€4.4 million in the same period last year) and the fair value loss of financial assets held at fair value through profit or loss of €2.9 million (€2.7 million in the same period last year).

Cash position

Cash and cash equivalents and current financial investments totaled €5,114.7 million on 31 March 2021 (€5,169.3 million on 31 December 2020, including the cash and cash equivalents included in the assets classified as held for sale).

A net decrease of €54.6 million in cash and cash equivalents and current financial investments was recorded during the first three months of 2021, compared to a net decrease of €58.4 million during the first three months of 2020. This net decrease was composed of (i) €127.7 million of operational cash burn, (ii) offset by €2.3 million of cash proceeds from capital and share premium increase from exercise of subscription rights in the first three months of 2021, (iii) €3.6 million of negative changes in (fair) value of current financial investments and €45.7 million of mainly positive exchange rate differences, and (iv) €28.7 million cash in from disposal of subsidiaries, net of cash disposed of.

The operational cash burn (or operational cash flow if this performance measure is positive) is a financial measure that is not calculated in accordance with IFRS. Operational cash burn/cash flow is defined as the increase or decrease in our cash and cash equivalents (excluding the effect of exchange rate differences on cash and cash equivalents), minus:

i. the net proceeds, if any, from share capital and share premium increases included in the net cash flows generated from/used in (–) financing activities

ii. the net proceeds or cash used, if any, in acquisitions or disposals of businesses; the movement in restricted cash and movement in current financial investments, if any, included in the net cash flows generated from/used in (–) investing activities.

This alternative performance measure is in our view an important metric for a biotech company in the development stage.

The following table represents a reconciliation of the operational cash burn (–)/operational cash flow:

Three months ended 31 March
(thousands of €) 2021 2020
Increase in cash and cash equivalents (excluding effect of exchange differences) 379,129 864,695
Less:
Net proceeds from capital and share premium increases (2,258) (5,355)
Net sale of current financial investments (475,844) (942,738)
Cash in from disposal of subsidiaries, net of cash disposed of (28,696) -
Total operational cash burn (127,669) (83,398)

Cash and cash equivalents and current financial investments comprised cash at banks, short-term bank deposits, treasury bills and money market funds that are readily convertible to cash and are subject to an insignificant risk of changes in value. Our cash management strategy monitors and optimizes our liquidity position. Our cash management strategy allows short-term deposits with an original maturity exceeding three months while monitoring all liquidity aspects. Cash and cash equivalents comprised €1,358.0 million of term deposits which all had an original maturity longer than three months. All cash and cash equivalents are available upon maximum three months notice period and without significant penalty. Cash at banks were mainly composed of notice accounts and term deposits. Our credit risk is mitigated by selecting a panel of highly rated financial institutions for our deposits.

Cash invested in highly liquid money market funds represented €1,107.4 million (€1,571.9 million on 31 December 2020) and are presented as current financial investments on 31 March 2021. The current financial investments also include treasury bills, amounting to €1,453.3 million on 31 March 2021 (€1,454.4 million on 31 December 2020). Our portfolio of treasury bills contains only AAA rated paper, issued by Germany and The Netherlands. Our money market funds portfolio consists of AAA short-term money market funds with a diversified and highly rated underlying portfolio managed by established fund management companies with a proven track record leading to an insignificant risk of changes in value.

Cash and cash equivalents included in assets classified as held for sale - 7,884
Total cash and cash equivalents 2,553,950 2,143,071

On 31 March 2021, our cash and cash equivalents and current financial investments included \$1,007.9 million held in U.S. dollars (\$1,418.9 million on 31 December 2020) which could generate foreign exchange gains or losses in our financial results in accordance with the fluctuation of the EUR/U.S. dollar exchange rate as our functional currency is EUR. The foreign exchange loss (–)/gain in case of a 10% change in the EUR/U.S. dollar exchange rate amounts to €86.0 million.

Finally, our balance sheet held R&D incentives receivables from the French government (Crédit d'Impôt Recherche), to be received in four yearly tranches, and R&D incentives receivables from the Belgian Government, for a total of €142.3 million as at 31 March 2021.

Capital increase

On 31 March 2021, Galapagos NV's share capital was represented by 65,511,581 shares. All shares were issued, fully paid up and of the same class. The below table summarizes our capital increases for the period ended 31 March 2021.

Fair value re-measurements

Gilead warrants B

The issuance of initial warrant B was approved on 22 October 2019 by the extraordinary general meeting of shareholders and is not yet exercised by Gilead at 31 March 2021. Initial warrant B has been valued on the basis of a Longstaff-Schwartz Monte Carlo model. The input data used in the model were derived from market observations (volatility, discount rate and share price) and from management estimates (number of shares to be issued and applied discount for lack of marketability). The recognized fair value gain of €2.0 million was mainly the result of a decrease in the implied volatility of our share price as well as its evolution between 31 December 2020 and 31 March 2021. The fair value of the financial liability related to the initial warrant B amounted to €1.2 million on 31 March 2021 and was presented as a current financial instrument.

Subsequent warrant B is still subject to approval by an extraordinary general meeting of shareholders and is therefore still presented as issuance liability in our deferred income.

Approval of interim financial statements

The interim financial statements were approved by the management board on 5 May 2021.

Report on the review of the condensed consolidated interim financial statements for the three-month period ended 31 March 2021

The original text of this report is in Dutch

In the context of our appointment as the company's statutory auditor, we report to you on the condensed consolidated interim financial statements. These condensed consolidated interim financial statements comprise the consolidated statements of financial position as at 31 March 2021, the consolidated statements of income and comprehensive income / loss (-), the consolidated statements of changes in equity and the consolidated cash flow statements for the period of three months then ended, as well as selective notes.

Report on the condensed consolidated interim financial statements

We have reviewed the condensed consolidated interim financial statements of Galapagos NV ("the company") and its subsidiaries (jointly "the group"), prepared in accordance with International Accounting Standard (IAS) 34, "Interim Financial Reporting" as adopted by the European Union.

The consolidated statement of financial position shows total assets of 5 615 059 (000) EUR and the consolidated income statement shows a consolidated profit (group share) for the period then ended of 9 361 (000) EUR.

The management board of the company is responsible for the preparation and fair presentation of the condensed consolidated interim financial statements in accordance with IAS 34, "Interim Financial Reporting" as adopted by the European Union. Our responsibility is to express a conclusion on these condensed consolidated interim financial statements based on our review.

Scope of review

We conducted our review of the condensed consolidated interim financial statements in accordance with International Standard on Review Engagements (ISRE) 2410, "Review of interim financial information performed by the independent auditor of the entity". A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit performed in accordance with the International Standards on Auditing (ISA) and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion on the condensed consolidated interim financial statements.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the condensed consolidated interim financial statements of Galapagos NV have not been prepared, in all material respects, in accordance with IAS 34, "Interim Financial Reporting" as adopted by the European Union.

Signed at Zaventem, 6 May 2021. The statutory auditor
