THE GALAPAGOS GROUP

Letter from the management

Dear shareholder,

2021 was a year of reflection, resulting in refocused R&D activities and resized spend, as well as
commercial roll-out, with a major effort to launch Jyseleca® throughout Europe.

We made excellent progress with Jyseleca (filgotinib) and successfully completed the process
of becoming Marketing Authorization Holder (MAH) in Europe for our first medicine. Improving
independent
patients’
European biopharma is a major achievement to make that mission a reality for patients suffering
from chronic debilitating conditions.

lives is at the core of what we do, and becoming a fully integrated,

One year after receiving approval for Jyseleca in Europe for the treatment of adults with
moderate to severe rheumatoid arthritis (RA), we secured reimbursement in 14 countries,
including the major markets of Germany, France, Spain,
Italy, and Great Britain. As of
31 December 2021, we reported €14.8 million of Jyseleca sales in Europe out of a total in-market
performance of €25.7 million, supporting confidence in the potential of our filgotinib franchise in
Europe and in our own commercial capabilities.

We also received approval by the European Commission (EC), and most recently by the Medicines
and Healthcare products Regulatory Agency (MHRA) in Great Britain, for a second indication for
Jyseleca for patients suffering from moderate to severe active ulcerative colitis (UC). We are now
progressing full steam ahead with the commercial roll out and Jyseleca is currently on the market
for UC in Germany and the Netherlands, with other European territories to follow in the course
of 2022.

We announced the completion of patient enrollment in the global Phase 3 DIVERSITY study
with filgotinib in Crohn’s Disease (CD), with topline results anticipated in the first half of 2023.
In October, we announced that we will be solely responsible for all development activities for
DIVERSITY and the long-term extension study starting 1 April 2022. Gilead will make a one-
time payment of $15 million to support Galapagos with the remaining DIVERSITY trial costs, and
should the EC grant regulatory approval of filgotinib for the treatment of CD based on data from
the DIVERSITY trial, royalties payable by Galapagos to Gilead will be reduced by 30% across all
filgotinib indications, or 5.6% to 10.5% of net sales in Europe. These royalties are payable as of
2024.

Also for filgotinib, we were pleased to report on the primary endpoint with the MANTA and
MANTA-RAy studies investigating the effect on semen parameters,
indicating that 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.

Galapagos NV Annual Report 2021

THE GALAPAGOS GROUP

Differentiated portfolio

Note: filgotinib is approved for RA in EU and Japan, approved for UC in EU and filed for UC in Japan

Due to the unfavorable risk/benefit profile observed by an Independent Data Monitoring
Committee (IDMC) in the Phase 3 study of ziritaxestat (GLPG1690) in idiopathic pulmonary
fibrosis (IPF), we had to discontinue further development of this program. This not only was a
major setback for Galapagos but most importantly for patients suffering from this terrible disease
for which current treatment options remain limited.

In 2021, we also made important progress across our broader inflammation pipeline, most notably
with our TYK2 and SIKi programs. We observed clinical activity with our TYK2 inhibitor GLPG3667 in
a Phase 1b study in psoriasis (Pso), and we are currently finalizing a Phase 1 dose escalation study
in healthy volunteers. We reported results from the first patient studies of our SIKi program with
SIK2/3 inhibitor GLPG3970. The biological activity observed in the studies in Pso and UC highlights
the pioneering role we are playing to unravel the role of SIKi in inflammation, and support further
development of our SIKi portfolio. We are currently working on a set of follow-up SIKi compounds with
improved pharmacology and selectivity profiles, and plan to select a preclinical candidate to move
into a healthy volunteer study this year.

Beyond inflammation, we completed patient recruitment in our MANGROVE Phase 2 trial with
GLPG2737, a novel Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) inhibitor, in
autosomal dominant polycystic kidney disease (ADPKD), with results expected in 2023.

I am very proud of our committed teams for working tirelessly to bring novel mode of action
medicines to patients, and now that my tenure at the helm of this company is drawing to an end, I
could not be more honored to hand over the baton to Dr. Paul Stoffels on 1 April.1 As a co-founder
and board member in the early years, Paul has a keen understanding of our roots as well as who
we are today. I strongly believe that Paul’s strategic and inspirational leadership, along with his deep
knowledge of both the industry and Galapagos, make him the right next CEO to deliver tremendous
value to all stakeholders, including investors, shareholders, and patients.

R&D

In the field of inflammation:

We received approval in Europe from the EC for filgotinib 200mg (Jyseleca) for the treatment
of moderate to severe UC

Gilead announced that NICE recommended filgotinib for reimbursement for moderate to
severe RA patients in Great Britain

We initiated the FILOSOPHY Phase 4 study with filgotinib in RA

We and Gilead announced interim data on the MANTA and 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 announced completion of patient enrollment for DIVERSITY Phase 3 study with filgotinib
in CD including a 10-week induction phase, followed by a 47-week maintenance phase.
Topline results are anticipated in the first half of 2023

We reported encouraging exploratory data from the DIVERGENCE 2 trial with filgotinib in
fistulizing CD

We observed activity with TYK2 inhibitor GLPG3667 in Pso, with a generally safe and well
tolerated profile, and are currently completing a dose escalation study in healthy volunteers

We reported on biological activity with SIK2/3 inhibitor GLPG3970 in inflammation, and more
particularly in the CALOSOMA Phase 1b study in Pso and the SEA TURTLE Phase 2a study
in RA. Following the first read-outs
in UC. We did not see activity in the LADYBUG trial
with GLPG3970, we decided to terminate the TAPINOMA Phase 1b study with GLPG3970
in systemic lupus erythematosus due to slow recruitment in this trial and low likelihood of
success

We published the SELECTION Phase 3 data (Feagan etal. 2021) in TheLancet and 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, GLPG1690, in the ISABELA Phase 3 program in
IPF

Other clinical programs:

We announced the full recruitment for the MANGROVE Phase 2 trial with investigational CFTR
inhibitor GLPG2737 in patients with ADPKD

Corporate:

On 4 January 2021 we sold fee-for-service business Fidelta to Selvita for a total of
€37.1 million

We raised €3.3 million from subscription right exercises

We announced an extension of the lock-up period for Gilead’s current shares (currently
25.49%) in Galapagos to 2024

6

Galapagos NV Annual Report 2021

THE GALAPAGOS GROUP

We announced the planned departure of Piet Wigerinck, our Chief Scientific Officer, and the
planned retirement of Onno van de Stolpe, founder and Chief Executive Officer

We received the second installment of €75 million from Gilead in Q2, following payment of
an earlier installment of €35 million in January 2021, included under the revised filgotinib
agreement as announced in December 2020

We announced that we will assume operational and financial responsibility for the ongoing
DIVERSITY clinical study in CD with filgotinib and the long-term extension study. Gilead will
make a one-time payment of $15 million to Galapagos to support the costs of the DIVERSITY
clinical program, and if the EC grants regulatory approval based on data from the DIVERSITY
trial, royalties payable by Galapagos to Gilead will be reduced by 30% across all filgotinib
indications

As MAH for Jyseleca in RA and UC, we own full commercialization responsibilities across
Europe

Post-period events:

We are finalizing the Phase 1 study with SIK3 inhibitor GLPG4399 in healthy volunteers

On 11 February 2022, EMA announced that
its Pharmacovigilance Risk Assessment
Committee (PRAC) started an article 20 specific pharmacovigilance procedure to investigate
the safety data for all JAK inhibitors following recent results from the ORAL surveillance
study with tofacitinib (Xeljanz®, Pfizer) as well as the data from an observational study with
baricitinib (Olumiant®, Eli Lilly)

We appointed Dr. Paul Stoffels1 as Chief Executive Officer and successor for our current CEO
and founder Onno van de Stolpe effective 1 April 2022. Onno will stay on until October 31
2022 as an advisor to hand over his activities and support Paul in specific projects.

We received approval in Great Britain from the MHRA for filgotinib 200mg (Jyseleca) for the
treatment of moderate to severe UC. Gilead anticipates a decision for Jyseleca in UC from the
Japanese authorities in the first half of 2022

We announced Sobi as our third-party partner for the distribution and commercialization of
Jyseleca in Eastern and Central Europe, Portugal, Greece, and the Baltic countries

We decided to terminate the GLIDER Phase 2a study with SIK2/3 inhibitor GLPG3970 in
Sjögren’s disease

2021: Details of the financial results

After the sale of our fee-for-service business (Fidelta) to Selvita on the 4 January 2021 for a total
consideration of €37.1 million, we only have one remaining reporting segment. The results of
Fidelta, including the impact of the 2021 sale, are presented as “Net results from discontinued
operations” in our consolidated income statements for the year 2021 and 2020.

Net revenues from continuing operations

Our net revenues from continuing operations for 2021 amounted to €484.8 million, compared
to €478.1 million in 2020.

Galapagos NV Annual Report 2021

THE GALAPAGOS GROUP

We reported net sales of Jyseleca in 2021 amounting to €14.8 million, which reflects the sales
booked by Galapagos after the country-by-country transition from Gilead.

Collaboration revenues amounted to €470.1 million in 2021, compared to €478.1 million last
year. The revenue recognition linked to the upfront consideration and milestone payments in
the scope of the collaboration with Gilead for filgotinib, amounted to €235.7 million in 2021
(€228.1 million in 2020). The revenue recognition related to the exclusive access rights for Gilead
to our drug discovery platform amounted to €230.6 million in 2021 (€229.6 million in 2020).
Additionally we have recognized royalty income from Gilead for Jyseleca for €3.8 million in 2021
(compared to €16.2 million in 2020, which was mainly from income related to upfront payments
from a distribution agreement for the commercial launch of filgotinib in Japan).

Our deferred income balance on 31 December 2021 includes €1.8 billion allocated to our drug
discovery platform that is recognized linearly over 10 years, and €0.6 billion allocated to the
filgotinib development that is recognized over time until the end of the development period.

Results from continuing operations

We realized a net loss from continuing operations of €125.4 million in 2021, compared to a net
loss of €311.0 million in 2020.

We reported an operating loss amounting to €165.6 million in 2021, compared to an operating
loss of €178.6 million in 2020.

Cost of sales related to Jyseleca net sales in 2021 amounted to €1.6 million.

Our R&D expenditure in 2021 amounted to €491.7 million, compared to €523.7 million in 2020.
This decrease was primarily due to the winding down of the programs with ziritaxestat (IPF),
MOR106 (atopic dermatitis), and GLPG1972 (OA) and reduced spend on our other programs.
This was partly offset by costs increases for our filgotinib, Toledo (SIKi) and TYK2 programs, on a
yearly comparison basis.

Our S&M and G&A expenses were respectively €70.0 million and €140.9 million in 2021,
compared to respectively €66.5 million and €118.8 million in 2020. This increase was primarily
due to an increase in personnel costs resulting from an increase in headcount and other
operating expenses mainly driven by the commercial launch of filgotinib in Europe. This increase
was partly offset by higher cost recharges from us to Gilead in the scope of our commercial cost
sharing for filgotinib in Europe.

Other operating income (€53.7 million in 2021 vs €52.2 million in 2020) slightly increased, mainly
driven by higher grant income.

We reported a non-cash fair value gain from the re-measurement of initial warrant B issued to
Gilead, amounting to €3.0 million in 2021 (€3.0 million in 2020), mainly due to the decreased
implied volatility of the Galapagos share price and its evolution between 31 December 2020 and
31 December 2021.

Net other financial income in 2021 amounted to €39.6 million, compared to net other financial
loss of €134.2 million in 2020. Net other financial income in 2021 was primarily attributable to

8

Galapagos NV Annual Report 2021

THE GALAPAGOS GROUP

€57.2 million of currency exchange gains on our cash and cash equivalents in U.S. dollars, and
to €8.8 million of net interest expenses. The other financial expenses also contained the effect of
discounting our long term deferred income of €9.3 million.

Results from discontinued operations

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

Group net results

We reported a group net loss in 2021 of €103.2 million, compared to a net loss of €305.4 million
in 2020.

Cash, cash equivalents and current financial investments

Current financial
investments and cash and cash equivalents totaled €4,703.2 million on
31 December 2021 as compared to €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 cash and cash equivalents and current financial investments amounted to
€466.1 million in 2021, compared to a net decrease of €611.5 million in 2020. This net decrease
was composed of (i) €564.8 million of operational cash burn2, offset by (ii) €6.8 million positive
changes in (fair) value of current financial
investments and €59.9 million of mainly positive
exchange rate differences, (iii) €3.3 million of cash proceeds from capital and share premium
increase from exercise of subscription rights in 2021, and (iv) €28.7 million cash in from disposal
of subsidiaries.

Our balance sheet on 31 December 2021 included R&D incentives receivables from the French
government (Crédit d’Impôt Recherche3), and from the Belgian Government, for a total of
€144.0 million.

Outlook for 2022
Early in 2022, we announced the appointment of Dr. Paul Stoffels1 as successor for founder
and current CEO Onno van de Stolpe, effective 1 April 2022. Paul is widely recognized as an
inspirational industry leader with exceptional R&D as well as global executive experience, with an
outstanding track record of accelerated product development in biotech and pharma through
insightful acquisitions and strategic partnerships.

In 2022, we expect reimbursement decisions in most key European markets for Jyseleca in
UC, and we anticipate our distribution partner Sobi to progress further with reimbursement
discussions for Jyseleca in RA and UC in Eastern and Central Europe, Portugal, Greece, and the
Baltic countries. In Japan, our collaboration partner Gilead expects a decision on the use of
Jyseleca in UC in the first half of 2022.

Earlier this year, the EMA announced that its Pharmacovigilance Risk Assessment Committee
(PRAC) started an article 20 specific pharmacovigilance procedure to investigate the safety data
for all JAK inhibitors following recent results from the ORAL Surveillance study with tofacitinib4
as well as the data from an observational study with baricitinib5. Following initiation of this
procedure, all JAKi MAHs will be invited to submit evidence and we will continue to work with the
EMA. The European Commission has asked the EMA to give its opinion by 30 September 2022.

Within our broader inflammation portfolio, we expect the read out from a healthy volunteer
Phase 1b trial with JAK1 inhibitor GLPG0555 for application in knee osteoarthritis and from
multiple Phase 1 trials in healthy volunteers. We aim to progress our TYK2 inhibitor GLPG3667
into a Phase 2 program, following the dose escalation Phase 1 study currently being finalized,
also taking into account the current regulatory and competitive landscape for TYK2 as a class. We
aim to advance selected compounds with optimized pharmacology and selectivity from our SIKi
portfolio into the clinic. Within our fibrosis portfolio, we are evaluating the start of a Phase 2 trial
with chitinase inhibitor GLPG4716 in lung fibrosis.

For 2022 we anticipate a further significant reduction of our cash burn and expect to land
between €450 and €490 million. This includes sales for Jyseleca that we anticipate between €65
and €75 million.

We believe our strong cash balance affords us the opportunity to develop our pipeline through
internal as well as externally sourced assets. We expect our scientific expertise, strong leadership,
and growing commercial franchise to propel us forward as we rebuild a differentiated pipeline of
novel mode of action drug candidates to help patients in need of new treatment options.

We want to thank you for your continued support as we took important decisions and actions to
set our foundations for future growth. My 23 years at the helm of this company have been an
incredible journey and I am very pleased that Paul will take over as CEO. Together with the board
and our strong management team, we believe that we can look forward with confidence to the
future of our company.

Respectfully,

COVID-19 impact

As the COVID-19 pandemic continues, we continue to innovate to accommodate for the new
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 for 2021:

Staff
In 2021, we continued to follow the strict measures put in place to help prevent the spread
of the COVID-19 virus and protect the physical and mental health of our staff. We rolled
out our global and site-specific business continuity plans and continue to take appropriate
recommended precautions.

During lock-down periods, we arranged for essential tasks to be carried out within our
facilities. Consequently, the majority of our Research staff continues to work from the
office/labs, with periodic exceptions for local lockdowns during which no staff is allowed into
the facilities. For those employees coming to the office, we maintain stringent cleaning and
sanitation protocols, and we strictly respect social distancing policies at all times in order to
minimize risk of exposure.

Based on the learnings from the first year of the pandemic, we piloted and gradually
implemented a hybrid working model in 2021, in locations where the ongoing COVID-19
situation and corresponding local governmental measures permitted to do so.

Additionally, we learned that most of the international travel could 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 way-of-working has been retained and
has become part of our corporate travel guidance.

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

The scorecard of the research department objectives shows a similar productivity compared
to previous years, indicating that we were able to minimize the impact, at least on the short
term.

11

Galapagos NV Annual Report 2021

THE GALAPAGOS GROUP

Development portfolio
We have a business continuity plan for our clinical development programs. We closely
monitor each program in context of the current global and local situation of the pandemic
and the associated specific regulatory,
institutional, 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 were 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, amongst 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 to mitigate the study where necessary and to facilitate the interpretation and
reporting of results.

Filgotinib filing process UC
As of publication of this report, our collaboration partner Gilead had not been informed by
the regulatory agency in Japan of approval timeline delays.

Manufacturing and supply chain
To date, there has been no COVID-19 impact to the commercial supply of filgotinib. All sites
involved in the manufacturing of filgotinib are established sites that currently manufacture
other marketed products and are in good standing with the FDA and are GMP certified.
Galapagos became marketing authorization holder of filgotinib in the European Economic
Area and Great Britain end 2021, and is responsible for manufacturing. The same
manufacturing sites as Gilead continue to supply filgotinib except for secondary packaging
and labelling for which a new vendor has been selected.

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, and thus became partially
virtual. The teams invested in digital channels as part of the overall commercial build strategy,
and these channels are being utilized during our ongoing commercial launch. Thus far we
note no material impact on the relative competitiveness of 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. Nevertheless, healthcare systems are under pressure across
Europe, increasing the volatility in reimbursement procedures and potentially reducing the
number of new therapy options initiated by healthcare providers.

Strategy

Our mission is to develop and commercialize first-in-class medicines based on novel targets to
improve patients’ lives.

Using human primary cells, we discover which proteins (“targets”) play a key role in disease
pathways. We then identify and develop small molecules that are designed to inhibit these
targets, and thereby positively influence the course of the disease. This approach is designed to
address the root cause of the disease rather than just treating symptoms, and has produced a
differentiated pipeline of molecules.

In 2021, we became the official Marketing Authorization Holder (MAH) for Jyseleca in the
European Economic Area (EEA) and Great Britain, realizing our ambition to become a fully
integrated, independent European biopharma. We are committed to pioneering for patients, with
the aim to enrich our product pipeline to address unmet medical needs, both through internal
R&D efforts and externally sourced opportunities.

The key elements of our strategy include:

Maximize and capture the value of our target discovery platform and our differentiated
pipeline based on novel modes of action
We continue to scale-up our target and drug discovery productivity, and as a result of the
strategic revision exercise announced in 2021, we set goals to focus and adjust the overall
risk profile of our clinical pipeline. We also continue to explore additional modalities of
drug therapies, such as PROTACs1 and oligonucleotides, and are actively collaborating with
external research partners to accelerate the innovation process.

Grow our Jyseleca franchise in the European Union and Great Britain
We successfully completed the process of becoming MAH of Jyseleca following the amended
agreement with Gilead announced in December 2020 (see Notes to the consolidated
financial statements) and continue the roll-out of Jyseleca in RA and UC throughout the
European Union and Great Britain. Patient enrollment for DIVERSITY Phase 3 in CD was
completed in October 2021, and we anticipate topline results in the first half of 2023. Gilead
remains responsible for sales outside of Europe and obtained approval for filgotinib in RA in
Japan in 2020 where it is distributed by co-promotion partner Eisai. Gilead also submitted the
application for approval of filgotinib in UC in Japan and anticipates a decision for approval in
the first half of 2022.

Deploy stringent cost discipline and operational excellence to maintain a strong balance
sheet and execute to internal and externally sourced opportunities
Following a strategic review of operations in March 2021, we initiated a cost savings program
of €150 million on a full year basis, where more than 50% of these targeted savings were
realized in 2021. Meanwhile we diligently evaluate business development opportunities to
strengthen our R&D engine and product pipeline.

Galapagos NV Annual Report 2021

THE GALAPAGOS GROUP

Build long-term value and accelerate our pipeline with our collaboration partner Gilead
In July 2019 we and Gilead entered into a strategic R&D collaboration, giving Gilead access
to our innovative portfolio of compounds and our drug discovery platform, in return for a
$3.95 billion upfront payment and a $1.5 billion equity investment (including the exercise of
warrant A). Gilead is subject to a 10-year standstill, securing our long-term independence,
with a lock-up of the full 25.49% of outstanding shares currently held by Gilead until
22 August 2024.

We strongly believe that the long-term collaboration with Gilead is mutually beneficial: we
gain access to Gilead’s extensive experience in drug development and commercialization,
and Gilead has access to our platform and pipeline, with option rights to our current
and future programs outside Europe. If Gilead opts in, the program is co-developed, and
Galapagos and Gilead share all costs.

Following the amendment in 2020 of the arrangement for the commercialization and
development of filgotinib, we assumed sole responsibility for commercialization of Jyseleca in
Europe and for the clinical development for the majority of the ongoing trials with filgotinib.
For further details: see the Notes to the consolidated financial statements.

Going concern statement

To date, we have incurred significant operating losses, which are reflected in the balance sheet
showing €367.2 million accumulated losses as at 31 December 2021. We realized a consolidated
net loss of €103.2 million for the year ended 31 December 2021. Our existing current financial
investments and cash and cash equivalents of €4,703.2 million at 31 December 2021 will enable
us to fund our operating expenses and capital expenditure requirements at least for the next 12
months. The supervisory board is also of the opinion that additional financing could be obtained,
if required. Taking this into account, as well as the potential developments of our drug discovery
and development activities, the supervisory board is of the opinion that it can submit the financial
statements on a going concern basis. Whilst our current financial investments and cash and cash
equivalents are sufficient at least for the next 12 months, the supervisory board points out that if
the R&D activities go well, we may seek additional funding to support the continuing development
of our products or to be able to execute other business opportunities.

Risk management and internal control

Risk management is embedded in our strategy and is considered important for achieving our
operational targets.

To safeguard the proper implementation and execution of the group’s strategy, our management
board has set up internal risk management and control systems within Galapagos. The
supervisory board has delegated an active role to the audit committee members to monitor
the design, implementation and effectiveness of these internal risk management and control
systems. The purpose of these systems is to manage in an effective and efficient manner the
significant risks to which Galapagos is exposed.

The internal risk management and control system is designed to ensure:

the careful monitoring of the effectiveness of our strategy

Galapagos’ continuity and sustainability, through consistent accounting, reliable financial
reporting and compliance with laws and regulations

our focus on the most efficient and effective way to conduct our business

We have defined our risk tolerance on a number of internal and external factors including:

financial strength in the long run, represented by revenue growth and a solid balance sheet

liquidity in the short run; cash

business performance measures; operational and net profitability

scientific risks and opportunities

dependence on our alliance partners

compliance with relevant rules and regulations

reputation

The identification and analysis of risks is an ongoing process that is naturally a critical component
of internal control. On the basis of these factors and Galapagos’ risk tolerance, the key controls
within Galapagos will be registered and the effectiveness will be monitored. If the assessment
shows the necessity to modify the controls we will do so. This could be the situation if the external
environment changes, or the laws or regulations or the strategy of Galapagos change.

The financial risks of Galapagos are managed centrally. The finance department of Galapagos
coordinates the access to national and international financial markets and considers and
manages continuously the financial risks concerning the activities of the group. These relate
to the following financial markets risks: credit risk, liquidity risk, currency and interest rate risk.
Our interest rate risk is limited because we have nearly no financial debt. In case of decreasing
interest rates we will face a reinvestment risk on our strong cash position. The group does not
buy or trade financial instruments for speculative purposes. For further reference on financial risk

management, see note 33 of the notes to the consolidated financial statements. We also refer to
the Risk factors section of the annual report for additional details on general risk factors.

The company’s internal controls over financial reporting are a subset of internal controls and
include those policies and procedures that:

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect
the transactions and dispositions of the assets of the company

provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with IFRS as adopted by the EU, and that
our receipts and expenditures are being made only by authorized persons

provide reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use or disposition of our assets that could have a material effect on the financial
statements

Our internal control over financial reporting includes controls over relevant IT systems that have
an impact on financial reporting including accuracy and completeness of our account balances.

Since the company has securities registered with the U.S. Securities and Exchange Commission
(SEC) and is a large accelerated filer within the meaning of Rule 12b-2 of the U.S Securities
Exchange Act of 1934, the company needs to assess the effectiveness of internal control over
financial reporting and provide a report on the results of this assessment.

In 2021 management has reviewed its internal controls over financial reporting based on criteria
established in the Internal Control – Integrated Framework (2013) issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO) and engaged an external advisor
to help assess the effectiveness of those controls.

As described in Section 404 of the U.S. Sarbanes-Oxley Act of 2002 and the rules implementing
such act, we will
include the management and the statutory auditor’s assessment of the
effectiveness of internal control over financial reporting in our annual report on Form 20-F, which
is expected to be filed with the SEC on or around the publication date of the present annual
report.

Overview statutory results of Galapagos
NV

This overview only concerns the non-consolidated statutory results of Galapagos NV. These
results are part of the consolidated results as discussed in the Letter from the management.

Galapagos NV’s operating income in 2021 amounted to €916.0 million compared to
€1,037.0 million in 2020. This decrease is due to a lower turnover for €55.4 million, primarily due
to decreased milestone revenues, upfront payments and royalties related to the collaboration
agreement with Gilead. There was also a decrease due to internally generated intangible assets
– being capitalized R&D expenses – which contributed by €68.1 million less to operating income
than previous year. Other operating income amounted to €18.5 million, including €7.3 million
of grants recognized for R&D projects and €9.0 million recuperation of withholding taxes for
scientists.

The operating costs of 2021 amounted to €1,107.7 million compared to €1,146.0 million in 2020.
Services and other goods decreased substantially to €500.0 million compared to €543.0 million
in 2020, primarily due to decreased internal and external subcontracting for our preclinical
studies and clinical trials as well as decreased fees for insourced personnel.

Material purchases increased slightly from €10.3 million in 2020 to €13.1 million in 2021.

Personnel costs in 2021 amounted to €70.4 million compared to €59.9 million in 2020. The
number of employees at Galapagos NV at the end of 2021 amounted to 460 as compared to 508
at the end of 2020, excluding insourced personnel. The average number of FTE in 2021 however
increased to 487, compared to 436 in 2020.

Depreciation decreased to €401.8 million in 2021, compared to €467.8 million in 2020, and
related primarily to amortization of R&D expenses.

Galapagos NV’s 2021 financial income increased to €85.8 million compared to €25.8 million in
2020, while financial costs decreased to €28.1 million compared to €139.9 million in 2020. This
can mainly be explained by higher currency exchange gains on U.S. dollar in 2021. Non-recurring
finance income in 2021 consisted of €33.5 million of gain on sale of subsidiaries. Non-recurring
finance cost in 2021 consisted of impairment on financial assets.

Tax income recorded in 2021 of €20.2 million as compared to €21.6 million tax income in 2020,
related to tax incentives for investments in intangible fixed assets.

Galapagos NV capitalizes its incurred R&D expenses to the extent that the costs capitalized do
not exceed a prudent estimate of their value in use or their future economic benefits for the
entity. The ability to recover the capitalized amounts takes into account assumptions (e.g. future
peak sales, market share, sale prices, attrition rates regarding the successful completion of the
different R&D phases) which have a highly judgmental nature and depend on the outcome of
uncertain factors which are beyond the control of the entity (e.g. test results). The achievement of

23

Galapagos NV Annual Report 2021

THE GALAPAGOS GROUP

these assumptions is critical and may impact the recoverability of the amounts capitalized. R&D
expenses capitalized are fully amortized in the year in which they are capitalized.

Investments in fixed assets in 2021 amounted to €10.5 million, excluding the internally generated
assets. They consisted mainly of investments in intangible assets, being a license payment and
software, as well of costs for building improvements, new laboratory and IT equipment.

Non-current and current other receivables amounted to respectively €92.5 million and
€116.6 million and included the receivable for tax incentives amounting to respectively
€92.5 million and €6.6 million in 2021, compared to other receivables for tax incentives of
€78.3 million and €5.5 million in 2020.

Galapagos NV’s cash position at the end of 2021 amounted to €4,681.3 million.

The non-consolidated annual accounts of Galapagos NV which we submit for your approval were
prepared in accordance with Belgian accounting rules as well as with the legal and regulatory
requirements. They show a negative result. The financial year 2021 closed with a loss of
€92.7 million compared to a loss of €196.0 million in 2020. The non-consolidated annual
accounts of Galapagos NV show accumulated losses of €369.2 million as at 31 December 2021;
we refer to the Going concern statement for justification for the application of the valuation
rules under the going concern assumption.

In 2021, Galapagos NV did not make use of financial instruments.

Our broad pipeline and innovative drug
discovery engine

We discover and develop small molecule medicines with novel modes of action, several of which
are currently in clinical development in multiple diseases with high unmet medical need. Our
highly flexible discovery platform is applicable across many therapeutic areas.

Having achieved approval in the European Union, Great Britain, and Japan for our first ever
medicine in RA, and in the European Union and Great Britain in UC, we remain highly committed
to progressing our pipeline of drug candidates to address unmet medical needs and improve the
lives of millions. We refocused our product portfolio by critically examining the risk profile and
breadth of the pipeline.

Our differentiated clinical pipeline includes: 1) preferential
JAK1 inhibitor filgotinib, which is
approved for the treatment of RA in the European Union, Great Britain, and Japan, approved
for the treatment of UC in the European Union and Great Britain and submitted for approval in
UC in Japan, and currently in a Phase 3 trial in CD; 2) GLPG3667, a TYK2 inhibitor which showed
activity in a Phase 1b study in Pso in 2021; 3) GLPG4399, a SIK3 inhibitor currently in Phase 1; 4)
GLPG4716, a chitinase inhibitor in-licensed from OncoArendi, for which we anticipate to start a
Phase 2 study in lung fibrosis; and 5) GLPG2737, a CFTR-inhibitor, currently in Phase 2 in ADPKD.

In both our inflammation and fibrosis portfolios, we have multiple novel mechanism of action
candidates in early research. These programs are almost exclusively based on inhibiting targets
which were identified using our proprietary target discovery platform.

Versatile target discovery platform

Our target discovery platform provides a significant and substantial competitive advantage as it:

closely mimics the in vivo situation through the use of primary human cells with a relevant
trigger and readout for a specific disease phenotype;

identifies possible points to intervene in a disease pathway by suppressing the expression of
an individual protein in these pathways; and

enables us to rapidly analyze all of the druggable and non-druggable genes and select
pharmaceutically tractable protein targets directly by their ability to regulate key disease
biology.

A proof of success of this unique approach is demonstrated with filgotinib which acts on
preferential JAK1, a novel target which role in a specific disease was discovered by us using our
discovery platform.

The human genome consists of tens of thousands of genes which code for the proteins that
make up the human body. Nearly all chronic diseases and disorders are caused by a disruption
in the normal function of certain proteins. The main goal of the biopharma industry is to
discover and develop molecules that alter the activity or expression of these proteins so that
normal function returns and the cause of the disease is minimized or eliminated. One of the
main obstacles in discovering new drugs is to understand exactly which of the body’s tens of
thousands of proteins play a key role in a particular disease. Once these proteins are discovered,
they become targets for drug design. Finding these targets is one of the critical steps in the drug
discovery process. Our approach to target discovery is unique as our discovery platform focuses
on target identification using primary human cells, and incorporates patient data and pathway
screening early on, which we believe is the best way to study the effect that a protein might have
on the disease in the human body.

RESEARCH & DEVELOPMENT

To study proteins in human cells, we take advantage of the distinctive properties of viruses in
combination with RNA interference. The virus particle has the capability to infect almost every
type of human cell. The virus particles we work with have been engineered to act as a shuttle
vehicle, allowing the delivery of specific pieces of DNA into human cells. Additionally, these viruses
cannot replicate in the human cells they infect and do not interfere with the processes in the
cell. We engineered the viruses to carry small pieces of DNA, specific for individual human genes.
When the virus enters the cell, this piece of DNA leads to the production of a short sequence of
RNA that is processed in the cell to become “short interfering RNA,” or siRNA, which specifically
interferes with the mRNA of the protein it was designed for. As a result, the cells block, or “knock-
down,” the production of a certain protein and determine its impact on restoring normal function.

Our drug discovery research is based on the targets discovered using this technology. We started
by focusing on 6,000 human genes that belong to the small molecules druggable genome. We are
in the process of expanding our expertise with novel technologies such as oligonucleotide-based
techniques (antisense (AS) or siRNA) and degrader approaches (Proteolysis Targeting Chimeras
or PROTACs). These additions enable us to go broader and explore a broader set, coming closer
to the total of 20,000 protein-coding genes. Once a target is validated, we will use the most
suitable method to develop a potential therapeutic drug.

In small molecule drug discovery, an assay developed to assess the activity of the target is
subjected to large collections of chemical small molecules allowing the identification of chemical
structures that interact with the target to block or activate its activity. These chemical structures
are then modified to obtain a preclinical candidate, and upon successful optimization and
preclinical testing in animal models, the product candidate is tested in humans. Other
technologies to modulate relevant targets, such as oligonucleotides or PROTACs, are being
explored. In both cases the result is the removal of the target from the cells leading to the
prevention of its disease-contributing effects. Based on the properties of the target and its
cellular location, one or more modalities are selected and developed.

This discovery approach provides starting points for the discovery and development of drugs
with new modes of action. Since 2009, we have generated 49 preclinical candidates. Of these, 24
have entered first-in-human clinical development, 18 of which are believed to have novel modes
of action, and 15 entered into patient studies.

In addition to our pipeline of molecules in the clinic, we have multiple discovery programs
advancing toward clinical development.

Our inflammation franchise

Our first approved medicine

In 2021, we made significant progress with our Jyseleca (filgotinib) franchise. In September, we
celebrated Jyseleca’s first year on the market following the approval for the treatment of adult
patients with moderate to severe active RA in the European Union, Great Britain, and Japan.
Following the amended agreement with Gilead from late 2020, we successfully completed the
transfer of commercial activities from Gilead, and we are the proud MAH of Jyseleca in the
European Economic Area (EEA) and Great Britain since December 2021. In addition, filgotinib is
now also approved in the European Union and Great Britain for the treatment of adult patients
with moderate to severe UC, adding a second indication for filgotinib.

After years of hard work by so many, we are very excited to bring a new treatment option to
patients living with RA and UC throughout Europe.

The market for anti-inflammatory drugs in Europe is considerable:
it is estimated that the
inflammation market today in the five largest European markets is worth approximately
€6.1 billion, with about 50% of the current market going to RA therapies and about 50% to UC
and CD combined:

Jyseleca in RA

RA is a chronic autoimmune disease that affects more than three million patients in the United
States and Europe. RA is characterized by inflammation and degeneration of the joints. Patients
suffer from pain, stiffness, and restricted mobility due to a persistent inflammation of multiple
joints, ultimately resulting in irreversible damage of the joint cartilage and bone. The current
market for RA treatments in the EU5 is approximately €3.3 billion, with 60% of patients treated
with advanced therapies, including injectables, biological therapies and tsDMARDS.

Despite progress in the treatment of RA, there remains a considerable unmet need as sustained
remission is rare.1

Oral therapies targeting the Janus kinase (JAK) signaling pathway are approved to treat
inflammatory diseases.
In 2003, we discovered JAK1 as a novel, differentiated target in an
inflammation target discovery assay and subsequently developed filgotinib as a novel small
molecule inhibitor with preferential selectivity for JAK1.

Within the commercial space of the RA market in the EU5, we observe an expanding market share
for JAK inhibitors, compared to anti-TNF and other biologics. To date there are 4 JAK inhibitors
approved for the treatment of RA in EU5, including Jyseleca as a JAK1 preferential inhibitor. The
growth of the JAK class can be seen in both the total and dynamic (switchers and naïve patients)
market share, as shown in the figure below.

Regulatory approvals of Jyseleca in RA

In September 2020, Jyseleca (filgotinib 200mg and 100mg) obtained approval in European Union,
Great-Britain, and Japan for the treatment of adult patients with moderate to severe active RA.

The European Summary of Product Characteristics for filgotinib, which includes contraindications
and special warnings and precautions, is available at www.ema.europa.eu. The interview form
from the Japanese Ministry of Health, Labour and Welfare is available at www.info.pmda.go.jp.
The individual Great Britain and Northern Ireland Summary of Product Characteristics can be
found
at www.medicines.org.uk/emc and www.emcmedicines.com/en-GB/
northernireland respectively.

In 2020, Gilead received a Complete Response Letter (CRL) from the U.S. FDA for the New Drug
Application (NDA) for filgotinib. Consequently, Gilead decided not to advance with resubmission
in the U.S. for approval of filgotinib as a treatment for RA.

Commercialization of Jyseleca in RA

In 2021, we took full ownership of the manufacturing and commercialization of Jyseleca in Europe
and became MAH in 27 European countries, Iceland, Norway, and Liechtenstein. The medicine
is now reimbursed in 14 countries, including the major markets of Germany, France, Spain, Italy,
and Great Britain. In Central and Eastern Europe, Portugal, Greece and the Baltic countries,
our partner Sobi is responsible for the distribution and commercialization. The graphic below
represents the reimbursement progress throughout Europe since approval in September 2020.

Safety and efficacy in the filgotinib RA development program

Filgotinib has shown favorable results in terms of onset of action, efficacy, safety, and tolerability
from the FINCH Phase 3 and DARWIN Phase 2 clinical study programs.

As part of the filgotinib development program we initiated FINCH 4 in RA. The FINCH 4 study is a
multi-center, open-label, long-term extension study to assess the safety and efficacy of filgotinib
in patients with RA, enrolling subjects who completed either FINCH 1, FINCH 2, or FINCH 3
studies.

We and Gilead published integrated safety data from 7 RA studies in Annals of the Rheumatic
Diseases (Winthrop et al 2021). Data were integrated from 3 Phase 3 studies (FINCH 1 – 3), 2
Phase 2 studies (DARWIN 1, 2), and 2 long-term extension studies (DARWIN 3, FINCH 4) including
up to 5.6 years of filgotinib exposure, and over a median of 1.6 years. In this pooled analysis,
filgotinib was well-tolerated, and no new safety concerns were identified. Adverse events of
MACE and DVT/PE were rare and occurred in similar numbers among all treatment groups, and
with similar incidence rate across dose groups. The data highlight the acceptable safety and
tolerability profile of filgitinib as monotherapy and in conjunction with MTX/csDMARDs2 in RA.

In animal toxicology studies in the preclinical phase, filgotinib at an exposure dose above the
approved dose in humans induced adverse effects on semen parameters. Consequently, Gilead
and Galapagos committed to conducting dedicated male patient semen analysis studies in RA,
AS, and PsA patients, called MANTA-RAy, and in UC and CD patients called MANTA, concurrent to
all Phase 3 programs.

In March 2021, we were pleased to report on the primary endpoint with the MANTA and MANTA-
RAy studies investigating the effect on semen parameters,
indicating that 8.3% of patients
on placebo and 6.7% of patients on 200mg filgotinib had a 50% or more decline in sperm
concentration at week 13.

Biologic therapies for UC were dominated by tumor necrosis factor (TNF) antagonists for nearly
20 years, but anti-integrin and anti-interleukin (IL)-12/IL-23 antibodies have recently become
available. Although the introduction of advanced therapies has improved the treatment of some
patients, 30% of patients do not respond to treatment,1 and 19% to 59% of initial responders
don’t have a sustainable treatment response.2,3 Therefore, the medical need for improved
treatment efficacy with additional treatment options remains high.

Commercialization and regulatory progress of Jyseleca in UC

Following approval of Jyseleca (200mg) for the treatment of adults with moderate to severe UC
in the European Union in 2021 and in January 2022 in Great Britain, Jyseleca is now launched in
UC in Germany and the Netherlands, with roll-out throughout the rest of Europe anticipated this
year.

Filgotinib in CD

FITZROY Phase 2 and global DIVERSITY Phase 3 program in CD

CD is an IBD of unknown cause, resulting in chronic inflammation of the gastrointestinal (GI)
tract with a relapsing and remitting course. The market today for CD treatments is estimated to
approximately €1.8 billion in the five largest European markets.

Today, with the most advanced therapies, only 30 – 40% of CD patients on treatment achieve
prolonged clinical remission. There are currently no highly effective oral therapies approved for
CD and, like RA, treatment is dominated by injectable, biological treatments including anti-TNF
therapies. Anti-TNF agents have improved the management of CD; however, not all patients
respond to these drugs, and secondary loss of response during the first year is reported in up
to 50% of patients annually in placebo-controlled trials. Therefore, a considerable unmet need
remains with existing treatments.

Dysregulation of the JAK signaling pathway has also been associated with CD, which suggests
that filgotinib, with its preferential selectivity for JAK1, may offer an attractive alternative for the
treatment of CD. It is hypothesized that with preferential inhibition of JAK1, unwanted side effects
such as anemia may be reduced. This is of particular importance to IBD patients, who frequently
experience fecal blood loss.

The FITZROY Phase 2 trial (NCT02048618) evaluated the efficacy and safety of 200mg once-daily
filgotinib in 174 patients with moderate to severe active CD and mucosal ulceration, who were
either anti-TNF naive or anti-TNF failures. As reported in The Lancet (Vermeire et al. 2016),
the FITZROY trial achieved the primary endpoint of clinical remission at week 10, and filgotinib
demonstrated a favorable tolerability profile consistent with the DARWIN trials in RA.

Gilead initiated the Phase 3 DIVERSITY trial (NCT02914561) with filgotinib in CD in November
2016. In October 2021, we announced the completion of patient enrollment with topline data
anticipated in the first half of 2023. The DIVERSITY Phase 3 trial investigates the efficacy and
safety of 100mg and 200mg filgotinib once-daily compared to placebo in patients with moderate
to severe active disease including those with prior antibody therapy failure. The DIVERSITY trial
enrolled 1,374 patients from the U.S., Europe, Latin America, Canada, and Asia/Pacific regions.
Men and women in the DIVERSITY trial will be randomized to receive placebo, 100mg, or 200mg
filgotinib. Due to preclinical findings with filgotinib regarding semen parameters,
in the U.S.
randomization to 200mg was restricted to male patients who failed at least one anti-TNF therapy
and vedolizumab.

Following the amended agreement with Gilead, Galapagos will now become the sole sponsor
of the DIVERSITY trial and the long-term extension study. The parties intend to complete the
transfer no later than 30 June 2022. Under the terms of the agreement and upon completion of
the transfer, Gilead will make a one-time payment of $15 million to Galapagos. From 1 April 2022,

Our TYK2 program with GLPG3667

GLPG3667 is a reversible and selective TYK2 kinase domain inhibitor discovered by us.

In 2020, we tested the molecule in a healthy volunteer study. This Phase 1 study was a
randomized, double-blind, placebo-controlled dose escalation study evaluating safety,
tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of single and multiple ascending
oral doses of GLPG3667 for 13 days. Blood was drawn at multiple time points on Day 1 and
on Day 10 and stimulated ex vivo with several cytokines, including IFNα, to analyze the level of
inhibition in pSTAT signaling. The Phase 1 data showed an encouraging PK profile for once-daily
dosing and PD activity of GLPG3667:

weeks.

In July 2021, we announced positive topline results demonstrating that GLPG3667 was generally
well tolerated with a positive efficacy signal at week 4:

At week 4, four out of 10 patients in the high dose group had a PASI 50 response, defined
as at least a 50% improvement in PASI from baseline, compared to one out of 10 subjects
on placebo. There were no subjects with a PASI 50 response on the low dose of GLPG3667.
The 4 responders in the high dose group of GLPG3667 achieved a 52%, 65%, 74% and 81%
improvement respectively in their PASI scores from baseline, while the subject randomized
to placebo improved by 52%. Positive efficacy signals were also observed with the high dose
for other endpoints, including affected Body Surface Area and physician and patient global
assessment, versus placebo at week 4.

RESEARCH & DEVELOPMENT

Our SIK program

The Salt-Inducible Kinases (SIKs) belong to a novel target class in inflammation which we
discovered with our proprietary target discovery platform. The search for this novel target class
started with the ambition to find new anti-inflammatory drug candidates with a favorable efficacy
and safety profile relative to existing therapies. Although significant progress has been made with
novel therapies in recent years, for instance in psoriasis, there remains a high unmet need for
diseases related to overactive inflammation in joints, the bowel, and other organs.

Molecules discovered by us and which inhibit the different members of the SIK family have shown
the potential to modulate anti-inflammatory cytokines and pro-inflammatory cytokines. Targeted
and selective inhibition of SIK proteins brings an opportunity to restore the immune balance that
is typically out of balance in autoimmune diseases. This approach brings potential differentiation
from existing therapies that predominantly act by suppressing the immune system (see figure
below).

SIK portfolio

The family of SIKs contains three targets: SIK1, SIK2 and SIK3. In our search for compounds
acting on these targets, over 5,000 molecules were synthesized leading to more than 11 different
chemical series with multiple selectivity profiles. Our first efforts in the space led to compound
GLPG3312, a pan-SIK inhibitor, that was tested in Phase 1 and soon thereafter replaced by a
more selective SIK2/3 compound, GLPG3970. We initiated a series of early-stage clinical trials
with GLPG3970 and reported the first topline results in July 2021. These initial results resulted
in proof-of-mechanism data, elucidating the role of SIKs in inflammation. GLPG4399, a selective
SIK3 inhibitor, is in Phase 1, whereas tissue selective SIK2/3 inhibitor GLPG4605 and other SIK
inhibitors are advancing preclinically (see figure below). Several other compounds with different
profiles are being explored in discovery.

Pioneering role of SIKi in inflammation

We evaluated GLPG3970 in three randomized, placebo-controlled, double-blind studies:
i) a
Phase 1b study in patients with moderate to severe psoriasis and ii) two Phase 2a studies in
patients with moderate to severely active UC and RA. GLPG3970 or placebo were administered
orally once-daily for 6 weeks. The main objectives of the studies were to evaluate the safety and
tolerability of GLPG3970 as well as early signs of biological and clinical activity.

Across the three studies, GLPG3970 was generally safe and well tolerated. There were no deaths
nor serious adverse events, and the majority of treatment emergent adverse events (TEAEs) were
mild or moderate in nature.

CALOSOMA Phase 1b study in psoriasis

This randomized placebo-controlled study enrolled 26 patients with moderate to severe
psoriasis.

At week 6, four out of 13 patients on GLPG3970 had a PASI 50 response, defined as at least a 50%
improvement of baseline PASI, compared to none on placebo. Specifically, the four responders
achieved 50%, 50%, 56%, and 77% improvement in their PASI scores from baseline, reaching
statistical significance compared to placebo (p=0.002) at week 6. Positive signals of clinical activity
were also consistently observed for other endpoints, including affected Body Surface Area and
physician and patient global assessment, versus placebo at week 6.

This randomized placebo-controlled study enrolled 31 biologic-naïve patients with moderate to
severely active UC.

At week 6, positive signals on objective parameters such as endoscopy, histology, and fecal
calprotectin were observed in patients treated with GLPG3970. These findings did not translate in
a differentiation from placebo on change from baseline in the total Mayo Clinical Score (MCS), the
primary endpoint of this 6-week study (GLPG3970 -2.7, placebo -2.6). Seven out of 18 patients on
GLPG3970 who underwent endoscopy at week 6 met the criteria for Endoscopic Improvement,
defined as a score of 0 or 1 on the endoscopic response score, compared to one out of 9 patients
on placebo. The robustness of these signals will be further examined by assessing the correlation
to histological endpoints and tissue biomarker data.

Outlook SIK portfolio

From these three clinical studies we learned that the SIK pathway has the potential to play
an important role in inflammation and confirms the therapeutic potential of SIK inhibitors in
inflammatory diseases. Although we will not progress GLPG3970 into clinical development, the
study results are an essential part of the broad evidence package that we are assembling on our
SIK program. This strengthens our understanding of the best approach going forward. Today, we
have several molecules targeting SIK2 and SIK3 with higher potency, as well as more selective
molecules acting on SIK2 and SIK3 combined, that we aim to advance. Generating data with
relative inhibition of SIK2 versus SIK3 will deepen our knowledge of the safety profile and inform
us which isoforms best match with specific inflammatory conditions. We are currently finalizing a
Phase 1 study with our SIK3 inhibitor GLPG4399 in healthy volunteers.

RESEARCH & DEVELOPMENT

Our fibrosis portfolio

Fibrotic disorders represent an area of significant unmet need and we currently focus our R&D
efforts on Idiopathic Pulmonary Fibrosis (IPF) and adjacent indications involving lung fibrosis.

About IPF

IPF is a major cause of morbidity and mortality globally. It is a chronic, relentlessly progressive
fibrotic disorder of the lungs that typically affects adults over the age of 40. In 2018, 232,000
patients were diagnosed with IPF in the U.S., EU4 & UK and Japan,1 and this population is
expected to grow, due to improved diagnosis, the aging population and worsening air pollution.
The clinical prognosis of patients with IPF is poor, with median survival at diagnosis only two
to four years. There are currently no treatment options available that can reverse or stop the
progression of disease and improve the quality of life of patients. Lung transplantation may be
an option for some patients with progressive disease and minimal comorbidities.

Esbriet
(pirfenidone, marketed by Roche/Genentech) and Ofev (nintedanib, marketed by
Boehringer Ingelheim) are approved in the U.S. and Europe for the treatment of mild to moderate
IPF, and have been shown to slow the rate of functional decline in IPF. These medicines are gaining
ground as the standard of care worldwide with combined sales of $3.5 billion in 2020.2

While these approvals represent a major breakthrough for IPF patients, these novel therapies
do not stop the decline in lung function and patients continue to experience disease worsening.
Additionally, the adverse effects associated with these therapies are considerable3 (e.g., diarrhea
and liver function test abnormalities with Ofev; nausea and rash with Esbriet). There remains thus
a high unmet medical need for patients with IPF.

Our CFTR program with GLPG2737 in ADPKD

Autosomal dominant polycystic kidney disease (ADPKD) affects approximately 12.5 million people
worldwide and is the fourth leading cause of kidney failure today.1 Typically with this disease, both
kidneys enlarge with fluid-filled cysts, leading to kidney failure for approximately half of patients
by the age of 60, and requiring dialysis and possibly kidney transplantation.2 Patients may also
suffer from hypertension, abdominal pain, kidney infections, cyst ruptures, bleeding, and other
symptoms impacting quality of life. Other organs may be affected as well. Treatment is aimed at
relieving symptoms and controlling the accompanying hypertension. Currently, only one therapy
(tolvaptan3) is available to slow down the progression of cyst development and renal insufficiency;
however, not all patients tolerate this therapy.4

GLPG2737 is a Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) inhibitor which
was observed to be well tolerated by patients in previous clinical trials. It is hypothesized that
inhibition of the CFTR channel might reduce cyst growth and kidney enlargement for patients
with ADPKD.

We are currently investigating GLPG2737 in the MANGROVE Phase 2 randomized, double-blind,
placebo-controlled trial evaluating a once-daily oral dose of GLPG2737. GLPG2737 or placebo is
administered for 52 weeks, followed by an open-label extension period of 52 weeks, in 66 ADPKD
patients with rapidly progressing disease. The primary objectives of the trial are to assess the
effect on growth of total kidney volume over 52 weeks compared to placebo as well as overall
safety and tolerability. The secondary objectives include renal function, pharmacokinetics, and
pharmacodynamics.

Our R&D collaborations

Our collaboration with Gilead

In July 2019, we and Gilead entered into a strategic R&D collaboration, giving Gilead access to our
innovative portfolio of compounds and our drug discovery platform, in return for a $3.95 billion
upfront payment and a $1.5 billion equity investment (including the exercise of warrant A). Gilead
is subject to a 10-year standstill, securing our long-term independence, and a lock-up until
22 August 2024. Following the amendment of the arrangement for the commercialization and
development of filgotinib late 2020, we have assumed sole commercial responsibility in Europe
and clinical development for the majority of ongoing trials with filgotinib. For the remainder of
the pipeline, we are eligible to receive a $150 million opt-in fee per program, plus tiered royalties
ranging from 20 – 24% on net sales of all our products outside of Europe (ex-filgotinib) opted-
in by Gilead. Galapagos retains European commercialization rights. Gilead remains responsible
for filgotinib outside Europe, including in Japan where filgotinib is approved and co-marketed
with Eisai. We received payments from Gilead in connection with changes in responsibility for the
commercialization and development of filgotinib in Europe, and Gilead will receive royalties from
European net sales on filgotinib.

Following the amended agreement with Gilead announced in October 2021, Galapagos will
become now the sole sponsor of the DIVERSITY trial of filgotinib in CD and the long-term
extension study. The parties intend to complete the transfer no later than 30 June 2022. Under
the terms of the agreement and upon completion of the transfer, Gilead will make a one-time
payment of $15 million to Galapagos. From 1 April 2022, Galapagos will also be solely responsible
for all development costs for DIVERSITY. In addition, if the EMA grants regulatory approval of
filgotinib for the treatment of CD based on data from the DIVERSITY trial, then royalties payable
by Galapagos to Gilead will be reduced by 30% across all filgotinib indications and will become
5.6 to 10.5% of net sales in Europe. These royalties are payable as of 2024. Gilead remains
responsible for commercial activities outside of Europe. See also Notes to the consolidated
financial statements.

IBD targets discovered by Scipher, after which we have the exclusive option to progress up to five
targets into drug discovery and development. Under the terms of the agreement, we will retain
the rights for the discovery, development, and commercialization of therapeutics for the selected
target(s).

Our fibrosis collaborations

In January 2019 we announced a global collaboration with Fibrocor focused on novel targets
in IPF. Fibrocor is responsible for all research activities until
lead optimization, and we are
responsible for the further development and commercialization of the in-licensed programs.
Galapagos took an undisclosed equity stake in Fibrocor (privately held).

In November 2020 we entered into an exclusive collaboration and license agreement with
OncoArendi Therapeutics for the global development and commercialization of GLPG4716, a
chitinase inhibitor, in IPF. Under the terms of the agreement, we are responsible for the further
development and commercialization of the program. In addition, we have the option to initiate
negotiations to obtain development or commercialization rights for selected preclinical candidate
molecules.

In October 2018, we and AbbVie amended and restated our collaboration agreement whereby
AbbVie took over all programs in CF. AbbVie obtained exclusive worldwide rights to the current
CF investigational drug candidate portfolio developed by the two companies in the course of the

new therapeutic approaches to modulate a specific mechanism involved in IPF and potentially
in other fibrotic indications. e-therapeutics will be responsible for all computational activities
for the selected compounds. We will perform all experimental testing and are responsible for

Risk  
factors

Description of the risks of which 
investors should be aware

Foundation & Future

RISK FACTORS

Risks related to commercialization

The marketing and sale of filgotinib or future approved products may be unsuccessful or less
successful than anticipated. We are heavily dependent on the success of filgotinib, which is
approved for the treatment of RA in the European Union, Great Britain and Japan, and for the
treatment of UC in the European Union and Great Britain, and under regulatory review for the
treatment of ulcerative colitis in Japan.

The commercial success of filgotinib and of any future products will depend upon the degree of
market acceptance by physicians, healthcare payers, patients, and the medical community.

We have limited sales and distribution experience and are currently building a marketing and
sales organization. We expect to continue to invest significant financial and management
resources to continue to build these capabilities and to establish a European commercial
infrastructure. To the extent any of our product candidates for which we maintain commercial
rights is approved for marketing, if we are unable to establish marketing and sales capabilities or
enter into agreements with third parties to market and sell our products, we may not be able to
market and sell any product effectively, or generate product revenues.

Coverage and reimbursement decisions by third-party payers may have an adverse effect on
pricing and market acceptance. Legislative and regulatory activity may exert downward pressure
on potential pricing and reimbursement for any of our product candidates, if approved, that
could materially affect the opportunity to commercialize.

Risks related to product development and
regulatory approval

We operate adequate standard operating procedures to secure the integrity and protection
of our research and development activities and results, and the optimum allocation of our
R&D budgets. The progress of the most important research and development programs is
continuously monitored by our management board; they are discussed with the supervisory
board at least once per quarter, and supervisory board members with expertise in clinical and
scientific matters occasionally attend meetings with our scientific staff to discuss and assess such
programs. Nevertheless, due to our limited resources and access to capital, we must and have
in the past decided to prioritize development of certain product candidates; these decisions may
prove to have been wrong and may adversely affect our business.

We are heavily dependent on the success of our candidate filgotinib. We are also dependent
on the success of our other product candidates, such as GLPG2737, GLPG3667, GLPG4716,
GLPG0555, GLPG3121, and GLPG4399. Filgotinib is approved for use in RA in the European
Union, Great Britain and Japan and for use in UC in the European Union and Great Britain,
and is currently under regulatory review for use in UC in Japan. In addition, we are heavily
investing in our early-stage product pipeline, including our SIK early-stage compounds, and these

58

Galapagos NV Annual Report 2021

RISK FACTORS

drug candidates must undergo rigorous preclinical and clinical testing, the results of which are
uncertain and could substantially delay or prevent the drug candidates from reaching the market.

We cannot give any assurance that any product candidate will successfully complete clinical trials
or receive regulatory approval, which is necessary before it can be commercialized.

Our business and future success is substantially dependent on our ability to develop successfully,
obtain regulatory approval for, and then successfully commercialize our product candidate
filgotinib and our other product candidates. We are not permitted to market or promote any
of our product candidates before we receive regulatory approval from the FDA, the EMA, the
MHRA, the MHLW or any other comparable regulatory authority, and we may never receive such
regulatory approval for any of our product candidates. We cannot give any assurances that our
clinical trials for filgotinib or our other product candidates will be completed in a timely manner,
or at all. If filgotinib or any other product candidate is not approved and commercialized in certain
jurisdictions, we will not be able to generate any product revenues for that product candidate.

The regulatory approval processes of the FDA, the EMA, the MHRA, the MHLW and other
comparable regulatory authorities are lengthy, time consuming and inherently unpredictable,
and if we are ultimately unable to obtain regulatory approval for our product candidates, our
business will be substantially harmed.

Clinical testing is expensive and can take many years to complete, and its outcome is inherently
uncertain. Results of earlier studies and trials as well as data from any interim analysis of ongoing
clinical trials may not be predictive of future trial results, and failure can occur at any time during
the clinical trial process. If we experience delays in the completion of, or termination of, any
clinical trial of our product candidates, the commercial prospects of our product candidates will
be harmed, and our ability to generate product revenues from any of these product candidates
will be delayed. If filgotinib or any other product candidate is found to be unsafe or has lack of
efficacy, we will not be able to obtain or maintain regulatory approval for it and our business
would be materially harmed.

The rates at which we complete our scientific studies and clinical trials depend on many factors,
including, but not limited to, patient enrolment. Patient enrolment is a significant factor in the
timing of clinical trials and is affected by many factors including competing clinical trials, clinicians’
and patients’ perceptions as to the potential advantages of the drug being studied in relation to
other available therapies and the relatively limited number of patients. Any of these occurrences
may harm our clinical trials and by extension, our business, financial condition and prospects.

Our product candidates may cause undesirable side effects or have other properties that could
delay or prevent their regulatory approval, limit the commercial profile of an approved label, or
result in significant negative consequences following marketing approval, if any.

Undesirable side effects caused by our product candidates could cause us or regulatory
authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or
the delay or denial of regulatory approval by the FDA, the EMA, the MHRA, the MHLW or other
comparable regulatory authorities. The drug-related side effects could affect patient recruitment
or the ability of enrolled patients to complete the trial or result in potential product liability claims.
Any of these occurrences may harm our business, financial condition and prospects significantly.

59

Galapagos NV Annual Report 2021

RISK FACTORS

Filgotinib, if approved or following approval, may have a labeling statement warning for male
patients. In animal toxicology studies in the preclinical phase, filgotinib at an exposure dose
above the approved dose in humans induced adverse effects on semen parameters. Adjacent to
the filgotinib Phase 3 programs, we and Gilead are conducting dedicated male semen analysis
studies in CD and UC patients (MANTA) and in RA, psoriatic arthritis, or PsA, and ankylosing
spondylitis, or AS, patients (MANTA-RAy).

Even now when filgotinib has received regulatory approval or marketing authorization in certain
jurisdictions, other regulatory authorities may impose dosing restrictions that differ from the
approved dosing regimen in other jurisdictions.

Box warnings, labeling restrictions, dose limitations and similar restrictions on use could have a
material adverse effect on our ability to commercialize filgotinib in those jurisdictions where such
restrictions apply.

EMA announced that its Pharmacovigilance Risk Assessment Committee (PRAC) started an article
20 specific pharmacovigilance procedure to investigate whether certain serious risks associated
with the JAK inhibitors Xeljanz (tofacitinib) and Olumiant (baricitinib) are associated with all JAK
inhibitors authorized in the EU for the treatment of inflammatory disorders, including filgotinib.
If the outcome of the EMA’s safety review results in amendments to the marketing authorization
for filgotinib, other additional requirements that the EMA may put in place with respect to
the development of JAK inhibitors generally, or other future actions by the EMA and other
comparable regulatory authorities, then such delays or (perceived) adverse developments or
results may harm our business, financial condition and prospects significantly.

If we lose orphan product exclusivity or are not able to obtain such status for future product
candidates for which we seek this status, or if our competitors are able to obtain orphan product
exclusivity before we do, we may not be able to obtain approval for our competing products for
a significant period of time.

Risks related to our financial position and
need for additional capital

We are an integrated biopharmaceutical company with a first commercial launch and have not
yet generated significant income. Our operations to date have been limited to developing our
technology and undertaking preclinical studies and clinical trials of our product candidates.

Since our inception, and with the exception of the year 2019, we have incurred significant
operating losses. We expect to continue incurring significant research, development and other
expenses related to our ongoing operations, and to continue incurring operating losses for the
foreseeable future. We cannot be sure to generate future revenues from the sales of filgotinib,
our first product approved for commercialization in the European Union, Great Britain and
Japan in the third quarter of 2020. Because of the numerous risks and uncertainties associated
with pharmaceutical product development, we are unable to predict the timing or amount of
expenses and when we will be able to achieve or maintain profitability, if ever.

Galapagos NV Annual Report 2021

RISK FACTORS

We may require substantial additional future capital which may not be available to us on
acceptable terms, or at all, in order to complete clinical development and, if we are successful, to
commercialize any of our current product candidates. In addition, raising additional capital may
cause dilution to our existing shareholders, restrict our operations or require us to relinquish
rights to our product candidates or technologies. The incurrence of additional indebtedness
could result in increased fixed payment obligations and could also result in certain additional
restrictive covenants that could adversely impact our ability to conduct our business.

For further reference on financial risks in particular, see note 33 of the notes to the consolidated
financial statements.

Risks related to our reliance on third
parties

We are heavily dependent upon our collaboration arrangements with Gilead and certain other
third parties for the development and commercialization of our products and there can be no
assurance that these arrangements will deliver the benefits we expect.

In July 2019, we entered into a 10-year global research and development collaboration with Gilead.
In connection with our entry into the option, license and collaboration agreement, we received an
upfront payment of $3.95 billion and a €960 million ($1.1 billion) equity investment from Gilead.
Under the option, license and collaboration agreement, we will fund and lead all discovery and
development autonomously until the end of the relevant Phase 2 clinical study. After the completion
of the Phase 2 clinical study (or, in certain circumstances, the first Phase 3 study), Gilead will have the
option to acquire an exclusive commercial license to that program in all countries outside of Europe.
If the option is exercised, we and Gilead will co-develop the compound and share costs equally. In
addition, we are heavily dependent on Gilead for the commercialization of filgotinib and the further
development of our product candidate filgotinib outside of Europe. Gilead may not devote sufficient
resources or give sufficient priority to the programs in respect of which it acquires a commercial
license pursuant to the option, license and collaboration agreement. Furthermore, Gilead may not
be successful in the commercialization of filgotinib outside of Europe and further development and
commercialization of filgotinib or other programs for which it acquires a commercial license, even
when they do devote resources and prioritize their efforts for such programs.

the terms of

In addition,
the collaboration with Gilead and any collaboration or other
arrangement that we may establish may not ultimately prove to be favorable to us or may not be
perceived as favorable, which may negatively impact the trading price of the ADSs or our ordinary
shares. In addition, pursuant to the collaboration with Gilead, we are entitled to certain option
payments and tiered royalties, and milestone payments on certain products. There can be no
assurance that such payments will be sufficient to cover the cost of development of the relevant
product candidates.

We are subject to a number of additional risks associated with our dependence on our
collaborations with third parties, the occurrence of which could cause our collaboration
arrangements to fail. In particular, the collaboration we entered into in July 2019 is managed by
a set of joint committees comprised of equal numbers of representatives from each of us and

61

Galapagos NV Annual Report 2021

RISK FACTORS

Gilead. Conflicts may arise between us and Gilead, such as conflicts concerning the interpretation
of clinical data, the achievement of milestones, the interpretation of financial provisions or the
ownership of intellectual property developed during the collaboration, and there can be no
assurance that the joint committees will be able to resolve any such conflicts. If any such conflicts
arise, Gilead could act in a manner adverse to our best interests. Any such disagreement could
result in one or more of the following, each of which could delay or prevent the development or
commercialization of product candidates subject to the collaboration arrangements, and in turn
prevent us from generating sufficient revenues to achieve or maintain profitability:

reductions or delays in the payment of milestone payments, royalties or other payments we
believe are due;

actions taken by Gilead inside or outside our collaboration which could negatively impact
our rights or benefits under our collaboration including termination of the collaboration for
convenience; or

unwillingness on the part of Gilead to keep us informed regarding the progress of its
development and commercialization activities or regulatory approval or to permit public
disclosure of the results of those activities.

In addition to our collaboration with Gilead, we may also enter into future collaborations which
will give rise to similar risks, although our ability to enter into such collaborations may be limited
given the scale of our collaboration with Gilead.

If our global research and development collaboration with Gilead or other collaborations on
research and development candidates do not result in the successful development and
commercialization of products or if Gilead or another one of our collaboration partners
terminates its agreement with us, we may not receive any future research funding or milestone
or royalty payments under the collaboration. If we do not receive the funding we expect under
these agreements, our development of our product candidates could be delayed and we may
need additional resources to develop product candidates.

in establishing future development and commercialization
We may not be successful
collaborations, particularly given the scale of our collaborations with Gilead, and this could
adversely affect, and potentially prohibit, our ability to develop our product candidates.

trials, obtaining regulatory approval,
Developing pharmaceutical products, conducting clinical
establishing manufacturing capabilities and marketing approved products are expensive. Accordingly,
we have sought and may in the future seek to enter into collaborations with companies that have more
resources and experience. In the future, however, our ability to do so may be limited given the scale
of the 10-year global research and development collaboration that we entered into with Gilead in July
2019. If Gilead declines to exercise its option and we are otherwise unable to obtain a collaboration
partner for our product candidates, we may be unable to advance the development of our product
candidates through late-stage clinical development and seek approval in any market. In situations where
we enter into a development and commercial collaboration arrangement for a product candidate,
we may also seek to establish additional collaborations for development and commercialization in
territories outside of those addressed by the first collaboration arrangement for such product
candidate. If any of our product candidates receives marketing approval, we may enter into sales
and marketing arrangements with third parties with respect to otherwise unlicensed or unaddressed

62

Galapagos NV Annual Report 2021

RISK FACTORS

territories. Furthermore, there are a limited number of potential collaboration partners, and we expect
to face competition in seeking appropriate collaboration partners. If we are unable to enter into any
development and commercial collaborations and/or sales and marketing arrangements on acceptable
terms, or at all, we may be unable to successfully develop and seek regulatory approval for our product
candidates and/or effectively market and sell approved products, if any.

We rely on third party suppliers for which a reliable supply of materials is required in order to
avoid delays in the drug discovery and development process and commercial supplies of any
approved product. Most goods and services are provided by several different suppliers, which
mitigates the risk of loss of key suppliers.

Expanding the suppliers’ network can be time consuming as all source suppliers are subject
to rigorous ethical and quality control standards. Our suppliers are required to adhere to
contractual terms that include anti-bribery and anti-corruption provisions. Our general terms and
conditions of purchase also contain a specific clause on anti-bribery and anti-corruption. They
can be found on our website.

We have relied on and plan to continue to rely on contract research organizations, or CROs, to
monitor and manage data for our preclinical and clinical programs. We and our CROs also rely
on clinical sites and investigators for the performance of our clinical trials in accordance with the
If CROs do not

successfully carry out their contractual duties or obligations or meet quality standards, regulatory
requirements or expectations, our clinical trials may be extended, delayed or terminated and we may
not be able to obtain regulatory approval for or successfully commercialize our product candidates.
We do retain responsibility for all our studies and are required to and have put in place measures to
manage, oversee, and control our studies, including the CRO selection process, audits, strong focus
on deliverables, timelines, roles & responsibilities, and oversight of conduct of the studies.

We rely on clinical data and results obtained by third parties that could ultimately prove to
be inaccurate or unreliable. If the third-party data and the results that we rely on prove to be
inaccurate, unreliable or not applicable to our product candidates, we could make inaccurate
assumptions and conclusions about our product candidates and our research and development
efforts could be materially adversely affected.

Risks related to our competitive position

We face significant competition for our drug discovery and development efforts, and if we do not
compete effectively, our commercial opportunities will be reduced or eliminated.

The biotechnology and pharmaceutical industries are intensely competitive and subject to rapid
and significant technological change. Our competitors may develop drug products that render
our products obsolete or non-competitive by developing more effective drugs or by developing
their products more efficiently. In addition, our ability to develop competitive products would be
limited if our competitors succeeded in obtaining regulatory approvals for drug candidates more
rapidly than we were able to or in obtaining patent protection or other intellectual property rights
that limited our drug development efforts.

63

Galapagos NV Annual Report 2021

RISK FACTORS

Risks related to our intellectual property

Our ability to compete may decline if we do not adequately protect our proprietary rights.

We endeavor to protect our proprietary technologies and know-how by entering into
confidentiality and proprietary information agreements with our employees and partners, and by
setting up special procedures (e.g. with respect to the handling of the laboratory books).

Our commercial success depends on obtaining and maintaining proprietary rights to our product
candidates, as well as successfully defending these rights against third party challenges. We
will only be able to protect our product candidates, and their uses from unauthorized use by
third parties to the extent that valid and enforceable patents, or effectively protected trade
secrets, cover them. If we fail to maintain to protect or to enforce our intellectual property rights
successfully, our competitive position could suffer, which could harm our results of operations.

Pharmaceutical patents and patent applications involve highly complex legal and factual
questions, which, if determined adversely to us, could negatively impact our patent position. Our
success will depend in part on our ability to operate without infringing the intellectual property
and proprietary rights of third parties. We cannot guarantee that our business, products and
methods do not or will not infringe the patents or other intellectual property rights of third
parties. There is significant litigation activity in the pharmaceutical
industry regarding patent
and other intellectual property rights. Such litigation could result in substantial costs and be a
distraction to management and other employees.

The patent positions of biotechnology and pharmaceutical companies can be highly uncertain
and involve complex legal and factual questions. The interpretation and breadth of claims
allowed in some patents covering pharmaceutical compositions may be uncertain and difficult
to determine, and are often affected materially by the facts and circumstances that pertain to
the patented compositions and the related patent claims. The standards of the United States
Patent and Trademark Office, the European Patent Office, and other foreign counterparts are
sometimes uncertain and could change in the future. If we fail to obtain and maintain patent
protection and trade secret protection of our product candidates, we could lose our competitive
advantage and the competition we face would increase, reducing any potential revenues and
adversely affecting our ability to attain or maintain profitability.

We will not seek to protect our intellectual property rights in all jurisdictions throughout the
world and we may not be able to adequately enforce our intellectual property rights even in the
jurisdictions where we seek protection.

Filing, prosecuting and defending patents on our product candidates in all countries and
jurisdictions throughout the world would be prohibitively expensive, and our intellectual property
rights in some countries could be less extensive than those in the United States and Europe.
Consequently, we may not be able to prevent third parties from practicing our inventions in all
countries, or from selling or importing products made using our inventions.

64

Galapagos NV Annual Report 2021

RISK FACTORS

Risks related to our organization,
structure and operation

Our future success depends on our ability to retain the members of our management board
and to attract, retain and motivate qualified personnel. If we are not successful in attracting and
retaining highly qualified personnel, we may not be able to successfully implement our business
strategy. Attractive development and training programs, adequate remuneration and incentive
schemes and a safe and healthy work environment mitigate this risk.

We expect that if we continue to build our development, medical and commercial organizations,
we will require significant additional investment in personnel, management and resources. Our
ability to achieve our research, development and commercialization objectives depends on our
ability to respond effectively to these demands and expand our internal organization, systems,
controls and facilities to accommodate additional anticipated growth. If we are unable to manage
our growth effectively, our business could be harmed and our ability to execute our business
strategy could suffer.

We are currently further building our marketing and sales organization. To the extent any of our
product candidates for which we maintain commercial rights is approved for marketing, if we are
unable to establish marketing and sales capabilities or enter into agreements with third parties
to market and sell our product candidates, we may not be able to effectively market and sell any
product candidates, or generate product revenues.

Our information technology systems could face serious disruptions that could adversely affect
our business. Continuing an uninterrupted performance of our IT system is critical to the success
of our business strategy and operations. A recovery plan for data has been implemented, as well
as a system for interception of power failures. Fire walls and virus scanners provide an additional
and adequate protection. Our personnel should adhere to continuity plans and procedures
regarding access rights and installation of different programs. Business interruptions could delay
us in the process of developing our product candidates. This risk has a high potential impact, but
is mitigated by policies and procedures such as surveillance of the buildings, annual appraisals
and bonuses, and monthly management meetings.

including the European General Data
We have to comply with applicable data privacy laws,
Protection Regulation, or GDPR, which imposes strict obligations and restrictions on the
collection and use of personal data. In the ordinary course of our business, we collect and store
sensitive data. Many third party vendors that support our business processes also have access
to and process sensitive information. Although we have taken preventative measures and set
up procedures regarding data processing, data breaches, loss of data and unauthorized access
could still occur. These could result in legal claims or proceedings, liability under laws that protect
the privacy of personal information, including the GDPR, and significant regulatory penalties,
disrupt our operations and damage our reputation.

Despite our efforts to monitor social media and comply with applicable rules, there is a risk that
the use of social media by us or our employees to communicate about our drug candidates

65

Galapagos NV Annual Report 2021

RISK FACTORS

or business may cause us to be found in violation of applicable requirements. In addition, our
employees may knowingly or inadvertently make use of social media in ways that may not
comply with our social media policy or other legal or contractual requirements, which may
give rise to liability, lead to the loss of trade secrets, or result in public exposure of sensitive
information. Furthermore, negative posts or comments in social media could seriously damage
our reputation, brand image, and goodwill.

We may undertake strategic acquisitions in the future and any difficulties from integrating such
acquisitions could adversely affect our share price, operating results and results of operations.
We may acquire companies, businesses and products that complement or augment our existing
business. We may not be able to integrate any acquired business successfully or operate any
acquired business profitably. Integrating any newly acquired business could be expensive and
time-consuming. Integration efforts often take a significant amount of time, place a significant
strain on managerial, operational and financial resources, result in loss of key personnel and
could prove to be more difficult or expensive than we predict. As part of our efforts to acquire
companies, business or product candidates or to enter into other significant transactions, we
conduct business, legal and financial due diligence with the goal of identifying and evaluating
material risks involved in the transaction. Despite our efforts, we ultimately may be unsuccessful
in ascertaining or evaluating all such risks and, as a result, might not realize the intended
advantages of the transaction.

If we are unable to use tax loss carryforwards to reduce future taxable income or benefit from
favorable tax legislation, our business, results of operations and financial condition may be
adversely affected. We may incur unexpected tax charges, including penalties, due to the failure
of tax planning or due to the challenge by tax authorities on the basis of transfer pricing. Any
changes to Belgian and international taxation legislation or the interpretation of such legislation
by tax authorities may influence our activities, financial situation and results. Such potential
changes and their impact are monitored carefully by management and its advisors.

Being active in research and development in Belgium, France and the Netherlands, we have
benefited from certain research and development incentives. If the Belgian and/or the French
and/or the Dutch government decide to eliminate, or reduce the scope or the rate of, the
research and development incentive benefit, either of which it could decide to do at any time, our
results of operations could be adversely affected.

As a company active in research and development in Belgium, we also expect to benefit from
the “innovation income deduction” in Belgium. The innovation income deduction regime allows
net profits attributable to revenue from among others patented products (or products for which
the patent application is pending) to be taxed at a lower effective rate than other revenues. The
effective tax rate can thus be reduced up to 3.75%. At 31 December 2021 we had €301.3 million
of carryforward innovation income deduction in Belgium.

Our inability to qualify for the abovementioned advantageous tax regimes, as well as the
introduction of the minimum taxable base and any other future adverse changes of Belgian tax
legislation, may adversely affect our business, results of operations and financial condition.

We have received several technological innovation grants to date, to support various research
programs from an agency of the Flemish government to support technological innovation in

66

Galapagos NV Annual Report 2021

RISK FACTORS

Flanders. In 2021 we have also received a grant from the National Institute for Health and
Disability Insurance. If we fail to comply with our contractual obligations under the applicable
technological innovation grant agreements, we could be forced to repay all or part of the grants
received.

We annually establish a detailed budget that is submitted to the supervisory board for review
and approval. Our performance compared to the budget is continuously monitored by our
management board and is discussed with the supervisory board at least once per quarter.
For the establishment of our financial information, we have processes and methods in place
that enable the preparation of consolidated financial statements for our annual and quarterly
reporting. Our management reporting systems – which include an advanced integrated ERP
system – secure the generation of consistent financial and operational
information, allowing
management to follow-up our performance on a daily basis.

Our business may be adversely affected as a result of computer system failures. We may
suffer data leaks, security incidents or become the target of cyber-attacks, as a result of which
information and/or intellectual property may be materially
our financial assets, confidential
negatively impacted. We may not be able to successfully protect our computer systems against
unauthorized access by third parties.

The occurrence of unforeseen or catastrophic events, including extreme weather events and
other natural disasters, man-made disasters, or the emergence of epidemics, depending on their
scale, may cause different degrees of damage to the national and local economies and could
cause a disruption in our operations and have a material adverse effect on our financial condition
and results of operations. Man-made disasters, pandemics, and other events connected with the
regions in which we operate could have similar effects. For example, the impact of COVID-19 on
our business is uncertain at this time and will depend on future developments, but prolonged
closures may disrupt our operations and the operations of our agents, contractors, consultants
or collaborators, which could negatively impact our business, results of operations and financial
condition. Further, uncertainty around these and related issues could lead to adverse effects on
the economy of the United States and other economies, which could impact our ability to develop
and commercialize our products and raise capital going forward.

The armed conflict between Russia and Ukraine could cause a disruption in our operations. We
currently have ongoing clinical studies for filgotinib with CROs located in Ukraine and Russia. If
our CROs experience disruptions to their business due to the military conflict in Ukraine and the
sanctions against Russia, it could result in delays in our clinical development activities, including
delay of our clinical development plans and timelines, or could cause interruptions in operations
of regulatory authorities. The impact on ongoing pivotal studies such as DIVERSITY 1 will remain
limited. We continue to monitor the situation and are taking measures to mitigate the impact
on our ability to conduct clinical development activities. Interruptions or delays in our and our
CROs’ ability to meet expected clinical development deadlines or to comply with contractual
commitments with respect to the same, could lead to delays in our overall developmental
and commercialization timelines, which would adversely impact our ability to conduct clinical
development activities and complete them on a timely basis. Since 24 February 2022, we have
extended the focus of the business continuity plan to closely monitor each program in context
of the currently ongoing Ukraine-Russia crisis and the associated specific regulatory, institutional,
and government guidance and policies.

RISK FACTORS

Market risks relating to the Galapagos
shares

We have identified the following major market risks:

Possible volatility of share price
The market price of the shares might be affected by a variety of factors outside management
control, such as the global economic situation, the business development of competitors,
sector mergers and acquisitions; it is difficult to mitigate this risk.

Economic risk due to failure in confidence
General public confidence about future economic conditions or performance of us or our
suppliers or customers may impact the ability or willingness of others to trade with us.

Dilution through capital increases
Raising additional capital may cause dilution to our existing shareholders. By raising
additional capital through capital increases with cancellation of the preferential subscription
rights of our existing shareholders, these shareholders will be diluted.

Dilution through exercise of subscription right plans
The exercise of existing subscription rights can significantly increase the number of
outstanding Galapagos shares.

Inability to distribute dividends
We have a limited operating history and future profitability cannot be guaranteed. Galapagos
NV has significant losses carried-forward and will thus not be able to distribute dividends in
the near future. This can cause people to refrain from investing in Galapagos shares.

Reputational damage
High ethical standards are maintained throughout the entire organization at all levels. Laws
and guidelines are complied with. Our suppliers are required to adhere to contractual
terms which include anti-bribery and anti-corruption provisions. In addition, our external
consultants are required to comply with our Code of Business Conduct and Ethics and U.S.
Foreign Corrupt Practices Act Policy.

Belgian law provisions
There are several provisions of Belgian company law and certain other provisions of Belgian
law, such as the obligation to disclose important shareholdings and merger control, that may
apply to us and which may make an unfriendly tender offer, merger, change in management
or other change in control, more difficult. These provisions could discourage potential
takeover attempts that third parties may consider and thus deprive the shareholders of the
opportunity to sell their shares at a premium (which is typically offered in the framework of a
takeover bid).

Foundation & Future

CSR REPORT

Our commitment

Since the foundation of Galapagos in 1999, we have worked hard and continuously on bringing
novel medicines to patients. I am proud of, and grateful for, the dedication of our employees as
they have worked towards these goals, striving for innovation and knowledge while conducting
business in an ethical and responsible manner. Our core values and culture are engrained in our
DNA, as we build on these foundations for the future.

Our commitment to Corporate Social Responsibility (CSR) is intrinsically linked to our core
mission: to discover and develop novel mechanism of action medicines for diseases with high
unmet medical needs, to make a lasting positive contribution to society and improve the lives of
patients worldwide.

Based on our core mission, in 2018, we engaged with internal and external stakeholders across
our different locations to define the four material aspects of our corporate responsibility and
sustainability approach. These help us to identify and prioritize the issues that matter most to
our business in terms of growth, risk, and goals, and to our stakeholders, including patients,
investors, partners, and suppliers. The four material aspects have remained the
employees,
pillars of our CSR strategy and action plans in 2021 and ensure that we report on the subjects
that matter most.

71

Galapagos NV Annual Report 2021

CSR REPORT

Today, we are excited to announce that in 2022, we will embark upon a company-wide CSR
strategy to further strengthen the foundations for our sustainable future as an independent,
fully integrated European biotech. Supported by the members of our management board, we
have established a CSR Steering Committee, comprised of representatives from key departments
throughout the organization. We plan to review our materiality assessment with internal and
external stakeholders, to assess whether our current pillars best describe our contributions
to, and impact on, society. Based on this, we aim to define a long-term ambition, measurable
objectives, and a roadmap to improve performance and boost engagement. To increase our
reporting on sector-relevant objectives, aid transparency and improve access to goals and
performance, we intent to add further reporting frameworks in future CSR reports.

CSR REPORT

Material aspect 1: Driving innovation

We strive to discover, develop, and commercialize breakthrough medicines with novel
mechanism of action, addressing diseases where a high unmet medical need remains. Our
mission is to add years of life and to improve the quality of life of patients suffering from severe
diseases, with innovative medicines that offer alternative treatment options.

We are pioneering for patients

There is a real need for innovative medicines that address the underlying cause of a disease.
There are many diseases for which there is no approved therapy today, and many more diseases
for which current therapies leave room for improvement in patient outcomes. New mechanism
of action medicines offer patients and caregivers alternative clinical options. At the same time,
they have the potential to decrease the burden for society, by lowering healthcare costs.

We create value through science and
innovation

Based on our powerful drug discovery engine, we are building a differentiated pipeline of novel
product candidates to ensure continued innovation, with potential benefits to patients, healthcare
professionals and society. To deliver on our mission to improve people’s lives, we build partnerships
to accelerate science and innovation, while sharing knowledge with a wider community.

CSR REPORT

Accelerating science and innovation through
collaboration

Innovation is the key for us to deliver on our mission to improve people’s lives. We strive to spark,
establish, and endorse innovation at every level of our company. To realize that ambition, we
foster team work and actively collaborate with different partners, each with their own specific
experience, knowledge, and field of excellence.

Collaboration with academic institutions

We establish relationships and work closely with academic organizations and universities to
accelerate development and boost innovation in discovery, preclinical, and clinical development.

Our team in discovery partners with a number of renowned institutions and consortia, including:

Institut de Ricerca Biomedica (IRB) in Barcelona, to identify and validate up to 20 drug targets
in inflammation and fibrosis;

S. Fillatreau, Institut Necker Enfants Malades in Paris, in order to gain a deeper understanding
of the involvement of B-cell subtypes in human pathologies;

M. Mendoza, Genopole in Evry, to develop and use spatial transcriptomics approaches;

SMART Organ-on-Chip, a consortium of academic and industry partners, coordinated by
Prof.dr.ir.
Jaap den Toonder, Eindhoven University of Technology (TU/e), to develop a
standardized open modular approach to recapitulate tissue and disease biology, funded by
NWO.

To gain more insights in specific disease areas, we collaborate with a number of experts,
including:

For IBD:

Prof. Dr. Séverine Vermeire, University Hospital Leuven (Belgium) for IBD back-translation
approaches using patient samples (blood, colon biopsies);

Dr.ir. Paul Vos, INIMINI-health, Wageningen University (The Netherlands) to study health-
promoting nutrition and drugs using immune- and microbiota-competent intestine-on-a-
chip. This research aims to integrate microbiota and immunity into a miniaturized assays
and is funded by Health Holland.

For IPF:

Prof. Wim Wuyts, University of Leuven (Belgium) to discover targets and biomarkers in IPF
using IPF lung transplant samples.

For ADPKD:

VLAIO collaboration with Prof. Djalila Mekhali, University Hospital Leuven (Belgium) to
better understand cystogenesis in ADPKD;

Prof. Steven Ballet, Drug Innovation and Modulation research group at the Free
University of Brussels (Belgium) for oligonucleotides peptide conjugation for kidney
targeting.

Prof. Gerjo van Osch, HypOA, Erasmus Medical Center (The Netherlands) to understand
the early processes in osteoarthritis through single cell RNA sequencing and
development of in vitro assays that recapitulate relevant disease processes, funded by
Health Holland.

Our research throughout these different disease areas is reflected in our differentiated pipeline
as shown below:

Differentiated portfolio

Note: filgotinib is approved for RA in EU and Japan, approved for UC in EU and filed for UC in Japan

Beyond these specific disease areas, we partner with Exeter University (UK) to contribute to
sociological research around clinical trials in rare diseases, to optimize patient engagement and
expand access to clinical trials. The project will also cover ethnographic research on planning and
implementation of patient engagement activities at Galapagos. The collaboration started in 2021 and
will span a period of three years.

Furthermore, we welcome students through internships and study projects, while we support
our employees to collaborate with universities to obtain a doctoral research degree (PhD).

Collaborations with patient organizations and healthcare
providers

stakeholders, in 2021, we started working with three independent patient advisors and seven
representatives from key umbrella and therapeutic area-specific patient organizations to develop
the Galapagos Patient Partnership Charter (PPC).

In true Galapagos spirit, the Charter is about leading by example. We decided, from the start, to
co-develop it with the patient community.

Launched in early 2022, the Charter defines what we stand for, what partnering with patients
means to us, and our approach and commitments to working with and for patients.

To ensure continuity, we want to build on the great collaboration with patient representatives
and advocates that we are currently engaging with. We are in the process of setting up the
Galapagos Patient Engagement Council, a consultative body that will advise Galapagos on patient
engagement-related topics and act as a knowledge exchange platform between Galapagos and
the patient community.

We entered into a strategic R&D collaboration with Gilead in 2019. We strongly believe that this is
a mutually beneficial long-term collaboration, as we gain access to Gilead’s extensive experience
in drug development and commercialization, and Gilead to our platform and pipeline, with option
rights to our current and future programs outside Europe.

Additionally, we have:

Collaborations with Ryvu and Scipher Medicine to further expand our inflammation pipeline
and discover and develop novel targets in inflammation;

Collaborations with Fibrocor and OncoArendi to jointly work on innovative approaches to
treat severe fibrotic diseases.

In addition to these ongoing collaborations, we continue to diligently evaluate new business
development opportunities in our pursuit to bring innovation to patients.

Providing access to our knowledge

Promoting an open innovation model, while reaching out to a
wider community

At Galapagos, we are committed to communicate the results from patient studies in a
transparent way. Even if a clinical study has been terminated earlier than anticipated, we report
the findings, based on the endpoints defined in these trials and share these with the medical
community.

Open access publishing best serves our aim to make our observations in clinical development
available barrier free to the research and medical community as well as to other stakeholders.
Open access ensures that the highest quality, peer-reviewed evidence is available to anyone,
anywhere in the world. It improves transparency, advances medical science and, we believe,
ultimately improves people’s lives.

We are proud that amongst our peers, we are one of the very first to publish with open access
and as of October 2020 we, by our policy, make our publications freely accessible in peer-
reviewed scientific and medical journals.

Furthermore, as of 2020 we actively participate in Open Pharma initiative, a first-ever
collaborative, multi-sponsor, non-profit project. We believe that publications are the route to
credible, compliant pharma communications. Open Pharma’s long-term goal is to secure the
same terms for authors who publish company-funded research as those for authors who publish
research funded through other means. As such, all research findings are freely available to read
and reuse, from the date of publication.

In 2021, Open Pharma published recommendations for plain language summaries of peer
reviewed medical publications. We all believe that, as a minimum standard, publications should
include a plain language summary in the style of an abstract that is easily accessible and
straightforward to understand, free of expert jargon, unbiased, and non-promotional.

We promote careers in science through science, technology,
engineering, math (STEM) initiatives

We actively engage in promoting science education and careers in science. We joined a
consortium of more than 18 global companies and local organizations with one joint objective:

creating a spark for science, technology, engineering, and math, specifically targeting youngster
between the age of 10 and 14. Together with young people, we are engaging parents, teachers,
and businesses to achieve this goal, and are targeting schools, businesses, events, and online
channels, using an inclusive and gender-sensitive approach.

Our goals are to inspire children and youngsters, and to enhance access to STEM related
subjects. We aim to:

Demonstrate that major societal challenges such as biodiversity, climate change, vaccines,
and digitization can be tackled with STEM knowledge;

Collaborate with parents, teachers, and businesses to get STEM online and offline, in order
to bring it closer to the target audience;

Illustrate that STEM is for everyone, regardless of background, gender, and ethnicity, by giving
due attention to specific target groups.

Material aspect 2: Our employees are the
strength behind Galapagos

Employees are the key to our success in developing novel mechanism of action drugs that have
the potential to make a real difference for patients. Attracting, inspiring and retaining employees
and making Galapagos a great place to work are essential for the success of our company. Our
approach to talent stems from our corporate values and strategic talent initiatives.

‘MakeitHappen’ is core to our culture: people feel they can make an impact in our organization,
which is highly motivating. We ensure that this value is protected and managed as we continue
to develop as an organization.

We are dedicated to continuing to build a diverse workforce and to fostering an inclusive, open
and supportive work environment across our locations in Europe and the U.S.

As we aim to expand our differentiated pipeline in 2022, while rolling out our first marketed
product across Europe, our organization continues to develop and build expertise.

Gender Equality

We strive for gender equality across multiple dimensions,
including talent attraction, female
leadership, and talent pipeline development, pay, creation of an inclusive culture. We foster a
diverse and inclusive organization and protect each other against all forms of harassment and
discrimination. We support gender equality through policy development, representation, and
transparency.

In 2021, we celebrated the International Day of Women and Girls in Science, endorsing equal
access to, and participation in, science for women and girls. 60% of our R&D colleagues are
women and their talent and dedication are essential in our aim to help patients now and in the
future.

As described in the section on Material Aspect 1, we are part a consortium of companies working
on Science, Technology, Engineering, and Mathematics (STEM) initiatives for youngsters, with a
key focus on sparking interest in STEM amongst girls via targeted social media outreach that
speaks to them (www.dasgeniaal.be and www.cestgenial.be).

Our corporate culture

At Galapagos, we believe a strong culture is fundamental to our business success. Our spirit
of challenging ourselves without fear of failure underpins our work. Since this boldness is
fundamental to us – and we recruit exceptional people who are the right fit – we have defined
our culture in a behavioral framework as follows:

We act as a pioneer and are optimistic in our ambitions, motivated by innovation and
attracted by the unknown

We positively embrace change and adapt to circumstances. Failing on occasion doesn’t deter
us; it’s how we pick ourselves up that matters

We challenge ourselves and, in doing so, raise the bar of what is possible

Together, we want to create value and improve lives through science – and we continuously
strive to find ways to make it happen

87

Galapagos NV Annual Report 2021

CSR REPORT

As new colleagues from different backgrounds join us, we want to ensure our culture evolves
accordingly. We continue to develop structured, integrated systems and onboarding practices
that help us look in the same direction, because our culture transcends everything we do.

We invest in our employees

Our employees are at the core of everything we do.
In our continued efforts to enable a
great experience at Galapagos, we offer our employees the platform to grow, develop, fail,
learn, and succeed. Our ambitious business strategy offers great opportunities to keep pushing
boundaries and enhance skills and competencies with the aim of delivering innovative science
and breakthrough medicines to patients. We honor our successes, while constantly raising the
bar and allowing room for trial and error to drive innovation. We encourage our people to take
ownership, be entrepreneurial, and make a difference.

At Galapagos, we offer competitive and evolving remuneration packages to reward, recognize,
develop, and retain our employees in a way that aligns with the company’s strategy and culture.

Performance bonuses and,
sustainable performance and commitment, and reward employees for their contributions to our
success.

The benefits we offer vary from country to country, based on local customs and statutory
conditions. Employee benefits include insurance for critical risks and key life events, as well as
provisions for different forms of leave in support of work-life balance.

We aim to ensure an inclusive, open, and supportive professional environment across our
international locations. We organize regular engagement meetings across all our business units
to inspire and align teams behind our vision and ambition. Informal sessions with members of
our management board help to inspire new and long-term employees across our different sites.

We listen to our people through formal and informal channels established to ensure openness
and psychological safety. Focused surveys evaluate our actions, impact, and the agility of our
people processes and help us enhance the employee experience.

During the COVID pandemic, we helped employees manage this health crisis by providing
additional electronic equipment to facilitate working from home, organizing online mindfulness
sessions, and paying a stipend to cover the additional costs incurred through working from
home. We also undertook initiatives to create team cohesion and strengthen the feeling of
belonging to the Galapagos family.

We engage with local communities and charities

We want to be part of the communities in which we work and live. In 2021, we transformed our
annual Company Day, where we traditionally devote time to a range of social organizations and
green initiatives, into a cross-site 'We Care' initiative. Across our different locations, we engaged
with social and nature conservation organizations in a concerted way.

Material aspect 2: our actions in 2021

In 2021, talent engagement and retention became a clear priority, and a range of
activities supported this:

In 2021, we improved our candidate experience. Our governance, planning and
approach in the continued period of pandemic led to an increased use of
assessment and recruitment tools to assure and ensure talent fit with the
culture of the company. Virtual conversations and case-based presentations
aided the process

We consistently partnered with colleagues to promote references and build a
pipeline of talent, in line with our goal to hire and develop diverse talent

As we established operations across Europe, our talent base has become more
international and diverse, too

Onboarding was refined, to become more efficient, robust, and attractive. It led
to a smooth integration with our culture and values, motivating new colleagues
to find their way in the organization, understand what is expected from them
and know what systems and tools to use. All colleagues joining from Gilead in
our commercial organization participated in culture and value workshops to fully
embed them in our company DNA. All newcomers got assigned a ‘buddy’ as
guide and support for any questions during the first months

Employee well-being is critical to our success. In the context of the continued
pandemic, managers engaged in 'How are you' conversations with their team
members. More than ever, we wanted to make sure that every employee felt
safe, listened to, and cared for

We focused on enhancing the performance and unlocking the potential of all
employees by promoting the development of personal and professional skills. To
support continued development during the pandemic, learning journeys
remained virtual, with team building adapted to online and hybrid experiences

We capitalized on internal lateral mobility, which is demonstrated by the fact that
about 95 colleagues (of which 60% women) were assigned new roles with
increased responsibilities in 2021

Regular performance and development conversations played a crucial role in
ensuring we remain performance-oriented and develop employees for current
and future roles

We have created a financial support package for remote working, rolled-out new
family leave policies and an annual stock-based program, and improved various
local benefit offerings

89

Galapagos NV Annual Report 2021

CSR REPORT

We set the stage to achieve digital ambitions for HR, with the successful launch
of SAP SuccessFactors. We initiated the employee self-service journey, supported
by strong change management and user-adoption practices to ensure a smooth
launch. We now have the architecture and analytics to consistently report on key
HR KPIs going forward and generate insights that matter to the business

We hired and onboarded 328 new colleagues, 80 of whom came from our
collaboration partner Gilead, as we took over the commercialization of Jyseleca
in regions in Europe that were initially covered by Gilead. We significantly
expanded our commercial organization and set up operations in six countries
(i.e. Austria, Finland, Sweden, Norway, Denmark, and Republic of Ireland) to
realize our ambition to become marketing authorization holder for Jyseleca in
Europe. We unfortunately had to rightsize our R&D and Shared Services
departments in view of our revised R&D portfolio following pipeline setbacks

Following recent events and in response to the strategic reset during the year,
we invested in regular communication plans, with extensive Questions and
Answers for senior leaders, to equip them to be closer to their teams.
Transparent presentations during townhall meetings helped employees put the
corporate news in perspective and maintain trust in our ability to overcome
headwinds with a plan and commitment

Future ambitions

‘We Care’ is part of our community engagement approach and we remain
committed to several initiatives, including:

supporting local STEM initiatives throughout our different sites

donating IT materials to local organizations for educational support

giving employees the opportunity to share any volunteering initiative on our
internal communication Yammer platform and allow others to engage
behind

The recruitment team will continue to focus on ensuring quality recruitment
externally but also supporting the internal redeployment and talent mobility
processes. We aim to improve our employer branding position via social media
campaigns and other career channels etc. to inspire and increase our outreach

At Galapagos, we continue to engage with early talents by collaborating with
universities/schools/academia to increase talent inflow via internships and/or
young graduate hire. Early pipelining is seen as a way to diversify the talent pool
and as a long-term objective to develop young talents into the leaders of the
future. We plan to remain competitive, evolving towards integrated talent
management that includes our employees, consultants, and our contingent
workforce

Our ambition is to improve the competitiveness of our talent and our
organization, and have a highly engaged workforce. We create opportunities for
our leaders to role model key behaviors, embody corporate values and create
the context for their teams to excel. Programs that generate transformative
learning in the space of personal and professional excellence will continually be
upgraded, while we embark on building strategic capabilities. We will continue to
enhance awareness of compliance and regulatory practices in a systematic way.
This journey will be further sharpened and enhanced towards establishing our
platform for success to promote growth in performance and potential in line
with industry benchmarks to prepare our workforce for the future

We continue to adopt cutting edge and digital solutions to boost candidate and
employee experience. Deployment of empowering people processes by
continuous improvement and streamlining, investing in the scalability and
consistency of our processes across the whole organization, will be instrumental
to success. We continue to invest in intuitive solutions to simplify HR processes
and employee self-service. To enhance the employee experience, we aim to
deploy digital tools that will provide them with solutions via a dedicated
knowledge base

91

Galapagos NV Annual Report 2021

CSR REPORT

Our focus will continue to be on evolving our competitive remuneration package
to support the attraction, retention, and engagement of talented employees,
helping Galapagos differentiate itself and creating a competitive advantage. In
particular, we hope to drive forward our wellbeing offering as a company and
explore further possibilities around the future of mobility. In addition, we will
look for further opportunities to bring to life our remuneration principles,
including reinforcing linkages between pay and performance, enabling
employees to share in the company’s success in alignment with shareholder
interests, remaining competitive in existing and new geographic markets, and
supporting employees and their families with locally relevant employee benefits

We will continue to drive and enable both mindset and practice when it comes to
organization agility. It starts with building a resilient organization, having the right
strategic capabilities and remaining highly responsive to our people and to the
context we operate in. Further, leadership and line manager capabilities will be
strengthened, internal mobility boosted along with our approaches to retain and
grow our talents, offering them diverse experiences across projects and
programs

We will continue to deploy initiatives to foster our strong culture to drive
innovation in science and make differentiating medicines available to as many
patients as possible. Increased focus on wellbeing, recognition and CSR
programs will contribute to becoming an even more inspiring, inclusive place to
work, where people can become their best selves. Our people are our
ambassadors. We put them in the spotlight and visualize how proud they are to
work for Galapagos and how proud the company is to work with such amazing
talents. We have an inclusive atmosphere of bringing people together from
various backgrounds to collaborate and deliver on meaningful solutions, both
internally within the company and as well as to our patients

Galapagos NV Annual Report 2021

CSR REPORT

Material aspect 3: Conducting business
ethically and responsibly

Our core business is the discovery and development of drugs with novel modes of action, and we
prioritize ethical behavior in all its aspects.

We believe that ethical behavior is particularly important and inherent to our business:
in
preclinical and clinical trials, expanded access to medicines currently in development for patients
who are not eligible to enroll in clinical trials, clear and adequate information to patients, clinical
trials that are tailored to the needs of patients and investigational site staff and our codes of
ethical conduct.

To ensure our business is compliant with regulatory and corporate policies, and that we conduct
business in an ethical way, we have developed a Compliance and Ethics Program, available on
our company intranet.

Animal welfare in drug development

Regulatory authorities worldwide require that new medicines are evaluated in both animals and
humans to ensure the quality, safety and efficacy of these products before granting approval.
Without animal testing, no new medicines would be approved.

We created the Galapagos Animal Welfare Committee in 2019 to oversee animal welfare activities
and to support the scientists in charge of animal testing. The Animal Welfare Committee put a
framework in place to enforce animal welfare best standards (policy, KPI, laboratory evaluations
and audits, recommendations, mitigation and corrective actions, regulatory and legal actions)
and to ascertain that our ethical values are well understood by our partners. The Animal Welfare
Committee reports directly to the Development and Research Management Committees and
CEO of Galapagos, and in addition to its advisory role, the Committee will regularly evaluate
animal study practices.

Galapagos explicitly forbids the unethical treatment of animals, such as neglect or cruelty, and
strives to provide animals with a good quality of life, while constantly seeking ways to make
improvements.

For non-clinical studies, including those that assess efficacy and safety of our product candidates,
we firmly stand behind the 'Three Rs’ principle: Refinement, Reduction, and Replacement. The
Three Rs principle is based on the premise that animals should be used only if a scientist’s best
efforts to find a non-animal alternative have failed, and that when animals are needed, only the

93

Galapagos NV Annual Report 2021

CSR REPORT

most humane methods should be used on the smallest number of animals required to obtain
valid information.

We have implemented practices that demonstrate our commitment and responsibility to refine,
reduce and replace non-clinical testing involving use of animals to the greatest extent possible,
and we will continue to research, promote, and implement alternative methods. We make more
frequent use of in silico (computer modelling) and in vitro (cellular testing) study designs and
approaches. Examples are the implementation of new modelling and simulation approaches for
supporting the toxicity assessment of our compounds as well as the use of invitrocardiomyocyte
assays to allow for the early assessment of potential cardiotoxicity issues. Other improvements
include the implementation of new pharmacological models
reducing animal-based
development or the review of procedures by the ethical and animal welfare committees.

We are engaged in several partnerships, including the Virtual Human Platform, an organization
that aims to accelerate the transition to animal-free safety assessments through innovation in
data science, human tissue culture models and transition management.

Our focus on animal welfare triggers a continuous improvement of, amongst others, the housing
conditions of animals (group vs single housing, size of cages), enrichment of the animal
environment (food, games, social activities), reviewing any irregularities, and the commitment to
immediate action. We expect the same ethos from third parties we work with such as Contract
Research Organizations (CROs) and academia. We carry out a thorough assessment of all third
parties and release an animal welfare policy that clarifies our expectations.

In Europe, compliance with Directive 2010/63/EU forms part of the pre-assessment and selection
process of the European laboratories that we use for non-clinical testing, and we monitor animal
welfare in the laboratories we engage with on a regular basis. Outside the European Union,
we require compliance in laboratories with local animal welfare regulations. In the U.S., for
example, we only work with laboratories that are accredited by the Association for Assessment
and Accreditation of Laboratory Animal Care. We also follow the national regulations defining
high standards for animal welfare for our internal studies in France. We systematically submit our
projects to the National Authorities for ethical approval and are regularly inspected in order to
maintain the highest accreditations.

Our clinical trials ethics

Galapagos sponsors and conducts clinical trials in accordance with applicable international
standards. The fundamental guidelines are the Declaration of Helsinki (and its amendments)
and Good Clinical Practice (including amendments), as well as Good Pharmacovigilance
Practice guidelines of the International Council for Harmonization. Our adherence to these
internationally recognized guidelines ensures the rights, safety, and well-being of participants in
our clinical trials.

for
In addition, other international guidelines such as The Belmont Report, Council
Coordination of International Medical Congresses guidelines, The Nuremberg Code, United
National Educational, Scientific and Cultural Organization’s (UNESCO) Declaration on Bioethics
and Human Rights form the ethical foundation for our trial activities. We comply with laws
and regulations in the countries/regions in which we are conducting our trials, including the

94

Galapagos NV Annual Report 2021

CSR REPORT

U.S. Code of Federal Regulations, the EU Directive on Clinical Trials and the EU Clinical
Trial Regulation (when applicable). Furthermore, we uphold our own internal procedures and
standards for clinical trials, irrespective of the country in which the trial is conducted. Overall, it
is our policy that the interest, safety, and well-being of trial participants and patients will always
supersede those of science and commerce.

Our trials are only initiated if they are scientifically and medically justified and when they are
externally validated by clinical experts. Moreover, they will always be reviewed by local health
authorities and ethical committees before initiation. Trial participants (or their legally authorized
representative) must give written consent after being properly informed of the trial, including the
risks and potential benefits. Participants are duly informed that they can withdraw from the trial
at any time, without any explanation, and then will receive appropriate care.

We, or our representatives, conduct regular site monitoring visits to ensure that clinical trials
are conducted in accordance with the applicable approved study protocol. Adverse events are
monitored and reported to authorities and ethical committees as needed, and appropriate
actions are taken when needed. Our Safety Monitoring Committee enables timely evaluation of
accumulating safety data of ongoing studies and adopts risk-management strategies to support
safe and ethical conduct of Galapagos studies.

An Independent Data Monitoring Committee (IDMC) may be introduced to act as an advisor to
Galapagos on whether to continue, modify, or terminate a trial based on periodic assessment of
trial data. The IDMCs are independent from Galapagos and are composed of members with no
conflicts of interest.

Our trials ensure proper indemnification of participants in case a product candidate or trial
procedure causes bodily harm.

We favor transparency and therefore, independent of the outcome, make patient study results
available to physicians and researchers, with full consideration for protection of patient data
privacy and commercial confidentiality. We report the outcome in accordance with the CONSORT
Statement, or Consolidated Standards of Reporting Trials, designed to improve transparency
around clinical trials.

Clinical trials and summary results are registered on Clinicaltrials.gov and/or the EU Clinical Trials
Register. Starting 1 January 2021, we committed to registering Galapagos sponsored Phase 1 to
4 clinical trials conducted in any geographical territory. We commit to making a summary of
the results of Galapagos-sponsored Phase 2 to 4 clinical trials publicly available within 6 months
of completion for pediatric studies, and 12 months for adult studies. As discussed above in
Material aspect 1, we provide publicly available open access to our publications in peer-reviewed
journals free of charge. We attempt to publish results in peer-reviewed journals, in accordance with
Good Publication Practice and the International Committee of Medical Journal Editor’s Uniform
Requirements for Manuscripts Submitted to Biomedical Journals, and at relevant scientific
meetings and congresses. As a publicly listed company, we also have the obligation to communicate
trial results by other means to the investor community, such as via press releases.

95

Galapagos NV Annual Report 2021

CSR REPORT

In some rare cases, patients are unable to participate in clinical trials and have exhausted
all available treatment options. Here, Galapagos has a policy in place to assess whether the
investigational product can be offered to a patient outside of a clinical trial, through a program
called 'expanded access’, also often referred to as 'compassionate use’. A full copy of our
Expanded Access Policy can be found on our website.

Patient safety for our first marketed product

We currently have one product, Jyseleca, on the market in the European Union, and Great
Britain. Adverse events and other information relevant to assess the benefit/risk profile of
Jyseleca are collected and evaluated by Galapagos in the frame of its pharmacovigilance system.
Individual and aggregated reports are submitted to the authorities as required. When needed,
appropriate actions are taken to ensure a positive benefit/risk balance for our patients. The
Safety Management Team, overseen by the Safety Board, enables timely evaluation of
accumulating safety data and adopts risk-management strategies to support the marketed
product. Galapagos has a Qualified Person for Pharmacovigilance who ensures the function
of the pharmacovigilance system and continuous monitoring of the benefit/risk profile of
Galapagos’ marketed products.

Our Code of Conduct

In 2021, we refined our Code of Conduct to fully reflect what it means to ‘Make it Happen the
Right Way’ at Galapagos.

Like a compass, our Code is there to navigate and steer us in the right direction, enabling us to
feel confident and proud of the choices we make, however hard they may be.

The new Code includes specific guidance to ensure that we live by the principles that are
important to us, as members of the Galapagos team:

Putting patients first

Acting ethically and with integrity

Being thoughtful and considered in our actions

Speaking up for what is right

Maintaining individuality and diversity

Holding ourselves accountable for our actions

Galapagos’ supervisory board is responsible for administering the Code. Our Compliance &
Ethics function is responsible to for designing and implementing the code through our
Compliance & Ethics Program and this is done in close collaboration with our General Counsel.

We expect our supervisory board members, management board members, and employees to
exercise reasonable judgment when conducting our business and encourage them to refer to
this Code frequently to ensure that they are acting within both the letter and the spirit of this
Code.

96

Galapagos NV Annual Report 2021

CSR REPORT

We expect our employees and third-party suppliers to conduct business ethically, with integrity
and respect for human rights. We expect them to turn away from conflicts of interest, corruption,
and fraud. All Galapagos employees and officers are required to read and absorb the Code which
is also available on our company website. Our suppliers are required to adhere to contractual
terms that include anti-bribery and anti-corruption provisions. We consider CSR criteria in our
vendor selection process as appropriate for the type of vendor that we are working with. Our

Making it Happen the Right Way - The Making Of…

Time for Change: the Why…

As an organization, we are coming through some significant changes not least having recently
been joined by our colleagues from Gilead. So now, more than ever, it is of key importance that
we take the time to think about our culture and what it means to be a member of the Galapagos
team; No better time for us to launch our new Code.

Like a compass, our Code is there to navigateus and steer us in the rightdirection, enabling us
to feel confident and proud of the choices we make, however hard they may be.

Meet our Compliance & Ethics Team: the Who…

The project to revamp our new Code of Conduct was led by our Compliance & Ethics team,
headed by Stephanie Wingrove, our Head of Compliance & Ethics. We asked her and the team
what inspired them to create this new Code;

Q: The new Code looks and feels dramatically different
to our old Code, and to those of the majority of our
peers. What inspired you?

A: Our team was really keen to create something that
was unique to Galapagos. As a team, we are interested
in how we can use the principles of behavioral science
to influence behavior within our organization and this
was at the forefront of our minds when we were
creating the Code.

Q: Could you give us an example of how you did this?

Stephanie Wingrove, Head of Compliance &
Ethics

it was really
A: Yes, we have a few! For example,
important that the language, tone and imagery we used
was likely to trigger an emotional response in our
readers. This is important because by doing this, the
document is far more likely to resonate with our people and to stick in their minds. People are
far more likely to “sign up” to a Code that has made them feel something and which aligns with
their own personal values.

CSR REPORT

Q: The Code incorporates quotes from employees across our organization- why did you choose
to include these?

A: This was about more than just including the quotes in our Code. For us, it was key that our
employees were engaged in the process of building the code and that their contributions played
a part in the final product- this is so important to ensure buy-in. As you can imagine, we received
a high number of quotes, and unfortunately not all could be included in the Code itself. But they
weren’t wasted; we incorporated these into our communications campaign for the new Code so
that everyone who participated saw the value of their contribution.

Q: This all sounds great. So, what next for the Code and the Compliance & Ethics team?

A: Well, Chapter 4 of our Code states that at Galapagos, we Speak Up for what is right. Cultivating
an environment in which every member of our team feels safe and empowered to use their voice
is a key part of building a strong culture. So, we will be rolling our Speak Up/ Listen Up campaign
over the course of 2022. We’d love to come back next year to tell you all about it!

Animal welfare

The Animal Welfare Committee took more than 20 major 'Refine, Reduce,
Replace’ initiatives and made decisions in line with our ‘Three Rs’ philosophy, and
these decisions informed the selection process for non-clinical partners

Clinical trial ethics

We launched the Galapagos Clinical Trials Portal in order to increase clinical
trial awareness and understanding for patients, their caregivers and healthcare
professionals. The portal includes a clinical trials finder for Galapagos later-stage
trials, and provides support to empower patients in preparing a clinical trials
conversation with their healthcare professional

In order to help patients make a well informed decision on potential clinical trials
participation, we redesigned our Informed Consent template in accordance with
the Health Literacy principles, taking into account applicable regulations

Code of Conduct

Since the launch of our new Code of Conduct in 2021, 93.5% of our employees
completed the training on our new Code of Conduct

During the onboarding process of new employees, we emphasize the
importance of our Compliance and Ethics Program, our Code of Conduct and
indicate all the channels available to them to raise questions and concerns

Material aspect 4: We care about the
environment, health, and safety

Our mission is to bring innovative medicines with novel modes of action to patients suffering
from severe diseases in the most sustainable way, caring about the health, safety and well-
being of our employees and respecting our planet by keeping our environmental footprint to a
minimum.

To render this more tangible, in 2021 we issued a global environmental, health and safety (EHS)
policy, defining key operational guidelines focusing on:

1. Ensuring regulatory compliance:

As we operate in a highly regulated sector which is subject to a set of strict laws and regulations
related to environmental impact, well-being and safety of employees, we identify, evaluate and
comply with all applicable EHS laws, in all countries in which Galapagos operates.

2. Growing sustainable operations:

To prevent work-related injury and illness, we provide safe and healthy working conditions
that are appropriate to the specific nature of the EHS risks to which workers and others are
exposed;

We minimize the organization’s carbon footprint and the creation of pollution and waste from
our operations throughout our value chain;

We strive to diminish our consumption of natural resources, using sustainable resources
where possible;

We pursue, evaluate and eliminate the health and safety risks to which our employees and
service suppliers are exposed, to prevent any incidents or accidents;

We foster openness and dialogue on EHS matters with our employees, employee
representatives and internal and external stakeholders;

We educate, train, motivate and involve Galapagos employees to work in a safe and
environmentally responsible manner, making every employee responsible for protecting
people and environment in and around their workplace.

Our health and safety performance data for 2021 show that no fatalities because of work-related
injuries or work-related ill-health were reported, nor did we have any high-consequence work-
related injuries.

Material aspect 4: our actions in 2021

Whilst a hybrid working policy was offered as a guidance for teams to start
working in the ‘next normal’ and to decide what works best for them during and
beyond the pandemic, specific measures to mitigate pandemic-related health
and safety risks were discussed at the newly established Cross-Site Operations
Meeting. These discussions resulted in global travel guidelines, guidance on
organizing and attending internal and external events, as well as habits to
consistently keep hygiene rules in mind. Thanks to disciplined adherence,
operations in 2021 were hardly impacted by the pandemic

The pandemic also led to an increased focus on physical and mental well-being,
aimed at providing employees with optimal working conditions whether at home
or at a Galapagos location. Specific actions included: surveys aimed at identifying
psychosocial risks, training sessions for line management aimed at recognizing
early symptoms of burn-out, a cash allowance to help install and maintain a
professional working environment at home, ergonomic training sessions aimed
at optimizing workstations at home, and mindfulness sessions. A first voluntary,
global vaccination campaign against the seasonal flu was successfully launched

Additional joint health and safety committees were established to ensure that
potential issues are proactively addressed, and proposed programs are
constructively challenged and optimized

We supported new operations in six countries, set up to grow our
commercialization efforts as part of an overall commercial ambition, by creating
a network of EHS experts providing country-specific advice on employee health,
safety, and wellbeing

Within this context, we strengthened our product stewardship capabilities to
ensure compliance with any Registration, Evaluation, Authorization and
Restriction of Chemicals (REACH) requirements

Criteria addressing social and environmental sustainability were included in the
selection processes of key vendors such as facility management providers and
contract manufacturing organizations, as well as in the design of any new
facilities (where BREEAM1 and WELL2 guidelines are applied), and certification is
sought when appropriate

BREEAM is a profound sustainability assessment for masterplanning projects, infrastructure, and building. It recognises
and reflects the value in higher performing assets across the built environment lifecycle, from new construction to in-use
and refurbishment.
The WELL Building Standard takes a holistic approach to health in the built environment addressing behavior, operations
and design, and is a performance-based system for measuring, certifying, and monitoring features of the built
environment that impact human health and well-being, through air, water, nourishment, light, fitness, comfort and mind.

Galapagos NV Annual Report 2021

CSR REPORT

Future ambitions

As part of our CSR strategy, we will define a long-term ambition, qualitative and
quantitative objectives and an implementation roadmap focusing on optimizing
employee health, safety, and well-being, promoting a circular mindset, and
minimizing our carbon footprint throughout our value chain. We will identify
relevant performance indicators to measure and report on the progress we
make and for inclusion in future reports

In support of this, we will launch specific 'Planet' and 'Wellbeing' workstreams at
global and local level to co-create and implement the roadmaps, also leveraging
existing initiatives such as 'Next Ways of Working'

To raise awareness and boost engagement, we will start celebrating the United
Nation’s World Safety Day on 28 April and World Environment Day on 5 June

We will define our ecological footprint, focusing on scope 1, 2 and 3 carbon
emissions, water consumption and waste management

We will include any agreed ambitions, objectives, and initiatives in our EHS
Management Systems aimed at mitigating any related risks

We will specifically review our processes related to emergency response,
maintenance management and contractor management, and integrate them
into a newly created Data Management System

Reporting on EU Taxonomy

EU Taxonomy 2021 statement

The European Commission’s action plan on financing sustainable growth led to the creation of an
EU classification system for sustainable activities, being an EU taxonomy. As a listed non-financial
company with more than 500 employees, Galapagos is in scope of the European Regulation
2020/852 of 18 June 20201 (the ‘EU Taxonomy Regulation’). For the reporting in 2021, Galapagos
has to disclose the proportion of its 2021 turnover, capital expenditures (‘CapEx’), and operating
expenses (‘OpEx’) eligible under the EU Taxonomy on sustainable activities. In the future eligibility
to the EU Taxonomy will need to be complemented with disclosure on the alignment with the
EU Taxonomy.

The EU Taxonomy Regulation introduces a classification system for environmentally sustainable
activities and an activity is deemed environmentally sustainable if it meets all of the following
overarching criteria:

substantially contributing to at least one of the six environmental objectives of the
EU Taxonomy Regulation: (i) climate change mitigation; (ii) climate change adaptation; (iii)
sustainable use and protection of water and marine resources; (iv) transition to a circular
economy,
(v) pollution prevention and control; and (vi) protection and restoration of
biodiversity and ecosystems;

not significantly harming any of these environmental objectives;

complying with minimum safeguards; and

complying with certain scientifically based technical screening criteria (‘TSCs’) established by
the EU Commission.

The EU has published a catalog of economic activities that can be considered as Taxonomy-
eligible activities for the first two environmental objectives, climate mitigation and climate
adaptation by means of using NACE2 codes. This EU Taxonomy Climate Delegated Act3 covers
the TSCs in relation to these two forgoing environmental objectives for more than 100 activities
within different sectors.

Following analysis of the EU Taxonomy legal framework4 and applying the NACE codes, we do
not consider our core business activities, being discovering, developing and commercializing
innovative medicines, to be in scope of the EU Taxonomy Regulation’s technical annexes on

Activités économiques dans la Communauté Européenne.
Commission Delegated Regulation (EU) 2021/2139 of 4 June 2021 supplementing Regulation (EU) 2020/852 of the
European Parliament and of the Council by establishing the technical screening criteria for determining the conditions
under which an economic activity qualifies as contributing substantially to climate change mitigation or climate change
adaptation and for determining whether that economic activity causes no significant harm to any of the other
environmental objectives.
Commission Delegated Regulation (EU) 2021/2178 of 6 July 2021 supplementing Regulation (EU) 2020/852 of the European
Parliament and of the Council by specifying the content and presentation of information to be disclosed by undertakings
subject to Articles 19a or 29a of Directive 2013/34/EU concerning environmentally sustainable economic activities, and
specifying the methodology to comply with that disclosure obligation, and the legislation set forth under footnote 1-3.

109

Galapagos NV Annual Report 2021

CSR REPORT

climate change mitigation and climate change adaptation. Our core economic activities qualify as
EU Taxonomy non-eligible activities.

For the determination of turnover, CapEx and OpEx during this analysis, we use the reported
data in the consolidated financial statements included in this report:

Turnover covers all business activities of Galapagos at 31 December 2021 and the
denominator can be reconciled with the 2021 IFRS Total revenue recognized pursuant to
€484.8 million and disclosed in note 6, being the revenues from commercial and
collaboration activities.

CapEx consists of additions to tangible and intangible assets during the financial year 2021
considered before depreciation, amortization and any re-measurements recognized by
Galapagos pursuant to IAS 38. The denominator can be reconciled with the sum of the
lines ‘Additions’ disclosed in notes 13 and 14 (total €63.4 million) of the consolidated financial
statements. The majority of CapEx is associated with building costs of new office spaces in
Belgium and the Netherlands, and is therefore non-eligible for the EU Taxonomy.

OpEx, according to the EU Taxonomy, is determined by the direct non-capitalized costs of
research and development, building renovation measures, short-term leases, maintenance
and repair and any other direct expenditures relating to the day-to-day servicing of assets
of property, plant and equipment by the undertaking or third-party outsources that are
necessary to ensure the continued and effective functioning of such assets. The majority of
OpEx is associated with our R&D expenditure.

Based on available data and the assessment of requirements, we have no eligible activities
to report. Taxonomy eligible Turnover, CapEx and OpEx is 0%, and it is 100% Taxonomy not
eligible. The “non-eligibility” under the EU Taxonomy refers to the fact that our activities currently
remain outside of the scope of the economic activities for which TSCs have been developed
under the Delegated Regulations. We want to clarify that revenues, CapEx and OpEx currently
considered non-eligible under the EU Taxonomy Regulation should not be interpreted as an
indication of our performance in pursuing or achieving certain corporate sustainability objectives
or our “greenness”.

We note that the required disclosures under the EU Taxonomy Regulation will keep evolving and
that we will continue to consider its impact as well as future reporting obligations.

Foundation & Future

CORPORATE GOVERNANCE

Galapagos’ corporate governance policies

As a listed company with its registered office at Mechelen (Belgium), Galapagos NV is required
to apply the Belgian Code of Companies and Associations (the "Belgian Companies Code") and
the 2020 Belgian Corporate Governance Code (the “2020 Code”). Both entered into force on
1 January 2020.

For the reporting year beginning on 1 January 2021, the 2020 Code was our reference code.
On 28 April 2020, following the amendment of our articles of association as a consequence of
the then newly applicable Belgian Companies Code, Galapagos' supervisory board approved an
updated corporate governance charter (which is available on our website, www.glpg.com). The
corporate governance charter applies in addition to the law, Galapagos' articles of association
and the corporate governance provisions included in the Belgian Companies Code and the
2020 Code. It describes the main aspects of corporate governance at Galapagos, including its
governance structure, the terms and functioning of the supervisory and management board and
its committees, and the rules of conduct.

For the reporting year beginning on 1 January 2021, the supervisory board strove to comply with
the rules of the 2020 Code and no deviations from the provisions of 2020 Code occurred. As a
result, this corporate governance statement does not contain any section making reference to
the “comply or explain” principle.

Our governance structure

The 2020 Code requires companies to make an explicit choice for one of the governance
structures provided for in the Belgian Companies Code. As of 28 April 2020, Galapagos has a
two-tier governance structure as provided by the Belgian Companies Code, with the supervisory
board replacing the board of directors, and the management board replacing the executive
committee.

112

Galapagos NV Annual Report 2021

CORPORATE GOVERNANCE

Two-tier governance structure

The supervisory board is responsible for the general policy and strategy of the company and
has all powers which are specifically reserved for it under the Belgian Companies Code. The
supervisory board also supervises the management board. The management board exercises
all powers which are not reserved for the supervisory board in accordance with the Belgian
Companies Code.

The supervisory board has established an audit committee and a nomination and remuneration
committee. Both have an advisory function. Finally, the management board has delegated the
daily management of the company to one management board member, i.e. its Chief Executive
Officer.

In addition to the information set out below, we refer to the Risk management and Risk factors
sections of this report for a description of the most important characteristics of our internal
control and risk management systems. The Risk management and Risk factors sections are
incorporated by reference in this corporate governance statement.

Proposed change of governance structure

In light of the recent leadership transition, the supervisory board reviewed whether the chosen
governance structure is still appropriate and decided to propose a new governance structure to
the general shareholders’ meeting, being a one-tier governance structure, consisting of a board
of directors and an executive committee to which certain powers are delegated by the board of
directors. On the date of this report, our articles of association have not yet been amended. The
supervisory board invites the shareholders of Galapagos to approve the introduction of a one-
tier governance structure at the occasion of the extraordinary shareholders’ meeting to be held
on 26 April 2022.

About the supervisory board

Galapagos' supervisory board consists of minimum five and maximum nine members. All
supervisory board members are non-executive directors, including the Chairman. At least three
supervisory board members are independent. On 31 December 2021, the supervisory board
consisted of eight members, five of whom are independent within the meaning of article 7:106
juncto article 7:87 of the Belgian Companies Code and provision 3.5 of the 2020 Code.

The supervisory board members are appointed by the shareholders’ meeting upon the proposal
of the supervisory board, for a renewable term of up to four years. Members of the supervisory
board whose mandate has come to an end may be reappointed. When a position on the
supervisory board becomes vacant, the remaining members may temporarily fill the mandate
until the next shareholders’ meeting appoints a new supervisory board member. Each member
of the supervisory board appointed this way by the shareholders’ meeting shall complete the
mandate of the member of the supervisory board he replaces, unless the shareholders’ meeting
decides otherwise. The nomination and remuneration committee nominates, for the approval
of the supervisory board, candidates to fill vacancies and advises on proposals for appointment
originating from shareholders,
in each case taking into account Galapagos’ needs and the
selection criteria determined by the supervisory board.

board: Dr. Parekh (Chairman), Mr. Rowe, Ms. Bosley, Dr. Kerr, Mr. Guenter, Mr. O’Day, Dr. Higgins
and Dr. Svanberg. Mr. Rowe, Ms. Bosley, Dr. Kerr, Mr. Guenter and Dr. Svanberg were appointed
as independent supervisory board members within the meaning of article 7:106 juncto article
7:87 of the Belgian Companies Code and provision 3.5 of the 2020 Code. In 2021, the supervisory
board was therefore composed of a majority of independent members.

At the annual shareholders’ meeting of 28 April 2021, the mandates of Dr. Parekh and Ms. Bosley
were renewed respectively for a term of four years and one year.

In 2021, the supervisory board thus consisted of four women and four men, representing four
different nationalities and different age categories.

During 2021, Galapagos NV complied with the Law of 28 July 2011 with respect to gender
diversification in the supervisory board, and in accordance with article 7:106 of the Belgian
Companies Code, the supervisory board will continue to monitor future compliance. In proposing
candidates, particular consideration is given to diversity in gender, age, nationality, educational and
professional background, as well as complementary skills, knowledge and experience. The profiles of

The supervisory board’s role is to pursue the long-term success of Galapagos. The board does
so by assuming the authority and responsibilities assigned to it by Belgian corporate law and
by combining entrepreneurial leadership with appropriate risk assessment and management.
Each of the supervisory board members’ expertise and experience is exemplified by the varied
professional activities they carry out and offices they hold. During its meetings in 2021, the
supervisory board dealt with matters pertaining to, among other things, our strategy and growth,
the new arrangement with Gilead for the commercialization and development of filgotinib,
the evaluation of other business development opportunities, the search and recruitment of a
suitable successor to lead our organization and a CSO, clinical trial results and shareholder
activism, convening of the shareholders’ meeting and preparation of resolutions to be submitted
for approval to the shareholders, and review and approval of our financial reporting.

In 2021, given the continuing COVID-19 pandemic and all related safety measures, the
supervisory board was unable to hold regular in person meetings, which were instead replaced
by digital meeting formats. Sixteen meetings took place by telephone conference or videocall
to discuss specific matters, including one meeting in the presence of a notary public (relating
to the issuance of Subscription Right Plan 2021 BE, Subscription Right Plan 2021 RMV and
Subscription Right Plan 2021 ROW). The meeting in the presence of a notary was attended by
Mr. Guenter and Dr. Svanberg via telephone conference; all other directors were represented
by proxy. The attendance rate for the other meetings, as identified in the table above, was as
follows: Dr. Parekh: 100%; Mr. Rowe: 93%; Ms. Bosley: 93%; Dr. Kerr: 100%; Mr. Guenter: 67%;
Mr. O’Day: 87%; Dr. Higgins: 93% and Dr. Svanberg: 100%. The overall attendance rate was 92%.
Mr. O’Day and Dr. Higgins recused themselves from one meeting because of a conflict of interest,

118

Galapagos NV Annual Report 2021

CORPORATE GOVERNANCE

in accordance with article 7:115, § 1, 4 of the Belgian Companies Code, as set forth in further
detail in the section titled Conflict of interests and related parties.

The supervisory board acts as a collegial body. A formal evaluation of the supervisory board
and its committees was carried out in September 2021. Each board member provided feedback
through individual assessment forms. The results were presented on an aggregate basis by
the secretary ad interim of the supervisory board and served as a basis for discussion by the
full supervisory board. This evaluation specifically addressed the functioning of the supervisory
board, the size and composition of the supervisory board, the interaction between the
supervisory board and the management board, and the functioning of the audit committee and
the nomination and remuneration committee.

The supervisory board has appointed a secretary entrusted with the functions set out in
Galapagos’ corporate governance charter.

In accordance with the articles of association, the extraordinary shareholders’ meeting of
Galapagos NV authorized the supervisory board to increase the share capital of Galapagos NV,
in one or several times, and under certain conditions set forth in extenso in the articles of
association of Galapagos NV.

This authorization consists of two parts. A general authorization for capital increases up to 20%
of the share capital at the time of convening the shareholders’ meeting of 22 October 2019 (i.e.
€67,022,402.04) was renewed and is valid for a period of five years from the date of publication
of this renewal in the Annexes to the Belgian State Gazette, i.e. 13 November 2019. A specific

renewed and is valid for a period of five years from the date of publication of this renewal in the
Annexes to the Belgian State Gazette, i.e. 31 May 2017. This specific part of the authorized capital
can, however, only be used in a number of specific circumstances and upon a resolution of the
supervisory board that all independent members of the supervisory board (within the meaning
of article 7:87 of the Belgian Companies Code) approve. This specific authorization will expire on
30 May 2022.

In 2021, Galapagos NV’s supervisory board made use of the right to increase the capital in the

2021, an amount of €41,775,187.16 still remained available under the general part of the
authorized capital and an amount of €13,717,929.80 remained available under the specific part
of the authorized capital.

board may,

subscription rights, even if such restriction or cancellation is made for the benefit of one or more
specific persons other than the employees of the group.

in Galapagos NV’s interest, restrict or cancel

Procedure for changes in Galapagos NV’s share
capital

In accordance with the Belgian Companies Code, Galapagos NV may increase or decrease its
share capital by decision of the extraordinary shareholders’ meeting approved by a majority of
75% of the votes cast, at a meeting where at least 50% of the share capital of Galapagos NV
is present or represented. If the attendance quorum of 50% is not met, a new extraordinary
shareholders’ meeting must be convened at which the shareholders may decide on the agenda
items, irrespective of the percentage of share capital present or represented at such meeting. In
this respect, there are no conditions imposed by Galapagos NV’s articles of association that are
more stringent than those required by law.

Within the framework of the powers granted to it under the authorized capital, the supervisory
board may also increase Galapagos NV’s capital as specified in its articles of association.

Galapagos NV Annual Report 2021

CORPORATE GOVERNANCE

Purchase and sale of Galapagos treasury shares

In accordance with the Belgian Companies Code, Galapagos NV may purchase, subject to the
provisions of the Belgian Companies Code, Galapagos NV’s own shares and dispose thereof by
decision of the extraordinary shareholders’ meeting approved by a majority of 75% of the votes cast,
at a meeting where at least 50% of the share capital of Galapagos NV is present or represented. If the
attendance quorum of 50% is not met, a new extraordinary shareholders’ meeting must be convened
at which the shareholders may decide on the agenda items, irrespective of the percentage of share
capital present or represented at such meeting. The aforementioned rules are also applicable to the
acquisition of shares of Galapagos NV by its subsidiaries.

The supervisory board has currently not been authorized by an extraordinary shareholders’
meeting to purchase or sell its own shares.

On 31 December 2021, neither Galapagos NV nor any subsidiary of Galapagos NV held any
shares in Galapagos NV, nor did any third party hold any shares in Galapagos NV on behalf of
Galapagos NV or any of its subsidiaries either.

Anti-takeover provisions in Galapagos NV’s articles of
association

Galapagos NV’s articles of association currently do not contain any anti-takeover provisions.

Anti-takeover provisions under Belgian law

Under Belgian law, public takeover bids for all outstanding voting securities of the issuer are subject to
the supervision of the FSMA. If the latter determines that a takeover violates Belgian law, it may lead to
suspension of the exercise of the rights attached to any shares that were acquired in connection with
the envisaged takeover. Pursuant to the Belgian Law of 1 April 2007 on public takeovers, a mandatory
takeover bid must be made when, as a result of its own acquisition or the acquisition by persons acting
in concert with it, a person owns, directly or indirectly, more than 30% of the securities with voting rights
in a company with registered office in Belgium whose securities are admitted to trading on a regulated
or recognized market. The acquirer must offer to all other shareholders the opportunity to sell their
shares at the higher of (i) the highest price offered by the acquirer for shares of the issuer during the 12
months preceding the announcement of the bid or (ii) the weighted average price of the shares on the
most liquid market of the last 30 calendar days prior to the date on which it became mandatory for the
acquirer to launch a mandatory takeover bid for the shares of all other shareholders.

Material contracts containing change of control
clauses

The second amended and restated collaboration agreement between Galapagos NV and AbbVie
S.à r.l. (“AbbVie”) dated 24 October 2018 contains provisions granting certain rights to AbbVie
upon the occurrence of a public takeover bid on our shares or a change of control in respect
of Galapagos NV, including, but not limited to clause 11.2 (Change in Control of Galapagos),
entitling AbbVie, to oblige Galapagos NV to take appropriate measures to avoid the disclosure of

128

Galapagos NV Annual Report 2021

CORPORATE GOVERNANCE

confidential information, to limit AbbVie’s reporting obligations to Galapagos NV, or, depending
on the stage in which the change of control occurs, to terminate the agreement.

Procedure for amendments to Galapagos NV’s
articles of association

Pursuant to the Belgian Companies Code, any amendment to the articles of association, such as
an increase or decrease in the share capital of Galapagos NV, and certain other matters, such as
the approval of the dissolution, merger or de-merger of Galapagos NV may only be authorized
with the approval of at least 75% of the votes validly cast at an extraordinary shareholders’
meeting where at least 50% of Galapagos NV’s share capital is present or represented. If the

Agreements between Galapagos NV shareholders

On the date of this report, Galapagos NV had no knowledge of the existence of any shareholders’
agreements between its shareholders.

Agreements with major Galapagos NV shareholders

On 14 July 2019, we and Gilead announced that we entered into a 10-year global research
and development collaboration. In the context of the transaction, Gilead also made an equity
investment in Galapagos. We also amended and restated the license agreement for filgotinib that
we originally entered into with Gilead on 16 December 2015. On 23 August 2019, the closing of
the transaction took place and we received an upfront payment of €3,569.8 million ($3.95 billion)
and a €960.1 million ($1.1 billion) equity investment from Gilead.

On 15 December 2020, we and Gilead announced that we agreed to amend our existing
arrangement for the commercialization and development of filgotinib again.

Terms of the equity investment

As part of the research and development collaboration, Gilead entered into a share subscription
agreement with us. On 23 August 2019, Gilead Therapeutics A1 Unlimited Company subscribed
to 6,828,985 new Galapagos shares at a price of €140.59 per share, including issuance premium.

Subject to the approval of Galapagos’ shareholders and certain other conditions, Gilead has the
right under the terms of the share subscription agreement to have two designees appointed
to our board of directors. The special shareholders’ meeting of 22 October 2019 approved the
appointment of Daniel O’Day and Linda Higgins as directors of Galapagos NV.

On 22 October 2019, our extraordinary shareholders’ meeting further issued a warrant to Gilead
Therapeutics A1 Unlimited Company, known as warrant A, that confers the right to subscribe
for a number of new shares sufficient to bring the number of shares owned by Gilead and its
affiliates to 25.1% of the issued and outstanding shares. Warrant A expires one year after the
issue date and the exercise price per share is €140.59. On 6 November 2019, Gilead exercised
warrant A and increased its ownership in Galapagos to 25.10% of the then outstanding shares.
Warrant A expired on 22 October 2020.

On 22 October 2019, Gilead Therapeutics A1 Unlimited Company was also issued another
warrant, known as the initial warrant B, that confers the right to subscribe for a number of new
shares sufficient to bring the number of shares owned by Gilead and its affiliates to 29.9% of the
issued and outstanding shares. The warrant will expire on 23 August 2024. The exercise price per
share will be the greater of (i) 120% multiplied by the arithmetic mean of the 30-day daily volume
weighted average trading price of the Galapagos shares preceding the date of the exercise notice
with respect to such exercise, and (ii) €140.59. Between 57 and 59 months of 23 August 2019,
subject to and upon approval by the shareholders’ meeting, Gilead Therapeutics A1 Unlimited
Company will be issued a warrant with substantially similar terms, including as to exercise price,
to the initial warrant B. This subsequent warrant B will expire on the earlier of the date that is five
years after the fifth anniversary of the closing and the date that the warrant is issued.

to certain standstill
Gilead and Gilead Therapeutics A1 Unlimited Company are subject
restrictions until the date that is 10 years following the closing (23 August 2019). Among other
things, during this time Gilead and its affiliates and any party acting in concert with them may
not, without our consent, acquire voting securities of Galapagos exceeding more than 29.9%
of the then issued and outstanding voting securities, and Gilead and Gilead Therapeutics A1
Unlimited Company may not propose a business combination with or acquisition of Galapagos.
The standstill restrictions are subject to certain exceptions as provided in the share subscription
agreement.

Pursuant to the terms of the share subscription agreement, Gilead and Gilead Therapeutics A1
Unlimited Company also agreed to certain lock-up provisions. They shall not, and shall cause their
affiliates not to, without our prior consent, dispose of any equity securities of Galapagos prior to
the second anniversary of the closing (23 August 2019). During the period running from the date
that is two years following the closing until the date that is five years following the closing, Gilead
and its affiliates shall not, without our prior consent, dispose of any equity securities of Galapagos
if after such disposal they would own less than 20.1% of the then issued and outstanding voting
securities of Galapagos. The lock-up restrictions are subject to certain exceptions as provided in
the share subscription agreement and may terminate upon certain events. In April 2021, Gilead
and Galapagos agreed to amend the share subscription agreement to extend the full lock-up of
all of Gilead’s securities of Galapagos to a period of five years until 22 August 2024.

Terms of the global research and development collaboration

We will fund and lead all discovery and development autonomously until the end of Phase 2.
After the completion of a qualifying Phase 2 study (or, in certain circumstances, the first Phase 3
study), Gilead will have the option to acquire a license to the compound outside Europe. If
the option is exercised, we and Gilead will co-develop the compound and share costs equally.
Gilead will maintain option rights to our programs through the 10-year term of the collaboration.
This term can be extended, at the discretion of Gilead, for up to an additional three years
thereafter for those programs, if any, that have entered clinical development prior to the end of
the collaboration term. On top, a final term extension can be granted in certain circumstances.

For all programs resulting from the collaboration (other than GLPG1972 and GLPG1690), Gilead
will make a $150 million opt-in payment per program and will owe no subsequent milestones.
We will receive tiered royalties ranging from 20 – 24% on net sales of all our products licensed by
Gilead in all countries outside Europe as part of the agreement. For GLPG1972, Gilead declined
to exercise its option under the collaboration agreement in November 2020. In February 2021,
the development of GLPG1690 (ziritaxestat) was discontinued.

Revised filgotinib collaboration

Under the terms of the new arrangement agreed in December 2020, we assumed all
development, manufacturing, commercialization and certain other rights for filgotinib in Europe.
Gilead retains commercial rights and remains marketing authorization holder for filgotinib
outside of Europe, including in Japan. The transfer was subject to applicable local legal, regulatory
and consultation requirements. Most activities transferred to Galapagos by 31 December 2021
and we intend to complete the transition by 31 December 2022. The new arrangement was
formalized in (1) the Transition and Amendment Agreement of 3 April 2021 pursuant to which
Gilead transitioned the exploitation of filgotinib in Europe to Galapagos by the end of 2021,

131

Galapagos NV Annual Report 2021

CORPORATE GOVERNANCE

(2) the DIVERSITY Letter Agreement of 6 September 2021 pursuant to which we and Gilead
agreed to transfer the sponsorship of and operational and financial responsibility for the ongoing
DIVERSITY study and its long-term extension study (LTE) study to Galapagos, and (3) the Second
Amended and Restated License and Collaboration Agreement of 24 December 2021, amending
and restating the existing collaboration agreement, with effect as of 1 January 2022. In March
2022, Gilead and Galapagos agreed to transfer the sponsorship of and the operational
responsibility for the MANTA study and its long-term extension to Galapagos.

Since 1 January 2021, we bear the future development costs for certain studies, in lieu of the
equal cost split contemplated by the previous agreement. These studies include the DARWIN3,
FINCH4, FILOSOPHY, and Phase 4 studies and registries in RA, MANTA and MANTA-RAy, the
PENGUIN1 and 2 and EQUATOR2 studies in PsA, the SEALION1 and 2 studies in AS, the
HUMBOLDT study in uveitis in addition to other clinical and non-clinical expenses supporting
these studies and support for any investigator sponsored trials in non-IBD conditions and
non-clinical costs on all current trials. The existing 50/50 global development cost sharing
arrangement will continue for the following studies: SELECTION and its long-term extension
study (LTE) in UC, DIVERSITY and its LTE, DIVERGENCE 1 and 2 and their LTEs and support for
Phase 4 studies and registries in Crohn’s disease, pediatric studies and their LTEs in RA, UC and
Crohn’s disease, and support for investigator sponsored trials in IBD. In September 2021, we and
Gilead agreed to transfer the sponsorship of the DIVERSITY study and its LTE study from Gilead
to Galapagos. The transfer is intended to be completed by 30 June 2022. From 1 April 2022,
Galapagos will also be solely responsible for all development costs for the DIVERSITY study and its
LTE study. In March 2022, we and Gilead agreed to transfer the sponsorship of the MANTA study
and its long-term extension from Gilead to Galapagos. The transfer is intended to be completed
by 31 December 2022.

All commercial economics on filgotinib in Europe will transfer to us as of 1 January 2022, subject
to payment of tiered royalties of 8 to 15 percent of net sales in Europe to Gilead, starting in
2024. If the European Medicines Agency grants regulatory approval of filgotinib for the treatment
of CD based on data from the DIVERSITY study, then royalties payable by Galapagos to Gilead
will be reduced by 30 percent across all filgotinib indications and will become 5.6 to 10.5
percent of net sales in Europe. In connection with the amendments to the existing arrangement
for the commercialization and development of filgotinib, Gilead has agreed to irrevocably pay
Galapagos €160 million, subject to certain adjustments for higher than budgeted development
costs. Gilead paid €35 million in January 2021 and an additional €75 million in April 2021 and
will pay €50 million in 2022. Furthermore, upon completion of the transfer of and operational
responsibility for the DIVERSITY study, Gilead will make a one-time payment of $15 million
to Galapagos in consideration for Galapagos assuming responsibility for the DIVERSITY study.
In addition, we will no longer be eligible to receive any future milestone payments relating
to filgotinib in Europe. However, we will remain eligible to receive tiered royalty percentages
ranging from 20% to 30% on Gilead’s global net sales of filgotinib outside of Europe and future
development and regulatory milestone-based payments of up to $295 million and sales-based
milestone payments of up to $600 million.

Our remuneration policy

A revised remuneration policy will apply as from 1 January 2022, subject to its approval by the
shareholders' meeting to be held on 26 April 2022. Such document is available on our website.

Remuneration report

Introduction: remuneration report 2021

Galapagos’ remuneration policy

Galapagos’ remuneration policy was prepared in accordance with the Belgian Companies Code.
the 2020 annual
Galapagos’ shareholders approved the current remuneration policy at
shareholders’ meeting with 68.21% of shareholder votes. The policy became effective as of
1 January 2020 and applies for the reporting year beginning on 1 January 2021. In this report we
will look back at 2021.

Galapagos encourages an open and constructive dialogue with its investors to discuss its
approach to governance, including remuneration. The increased disclosure in the remuneration
report reflects the input received from Galapagos’ shareholders over the years as well as
developments in the legislative framework, including individual disclosures for each supervisory
and management board member.

The objective of our remuneration policy is to attract, motivate and retain the diverse qualified
and expert individuals who are key in order to achieving our strategic and operational objectives.
We further aim to be competitive in the labor market by benchmarking against relevant peer
groups, incentivizing performance at the highest possible level, allowing for differential rewards
according to individual performance, avoiding discrimination on any grounds other than
performance, and reinforcing an open, fair, consistent and equitable culture.

Following the introduction of a one-tier governance structure, consisting of a board of directors
and an executive committee, to be proposed to the extraordinary shareholders’ meeting to be
held on 26 April 2022, a revised remuneration policy reflecting such change will be submitted for
approval of the annual shareholders’ meeting to be held on 26 April 2022.

Peer group and benchmarking

for

Galapagos’ remuneration policy takes into account relevant benchmarks with appropriate peer
companies and,
the management board members, also the group’s performance
management system. For the most recent benchmarking exercise executed in 2018, our
nomination and remuneration committee worked with Willis Towers Watson as external advisor.
Willis Towers Watson also provided external support for the benefit of the nomination and
remuneration committee in 2020. The peer group taken into consideration consisted of publicly
listed, early-stage high value biotechnology companies with a comparable market capitalization
in the U.S. and biotechnology and pharmaceutical companies in Europe. This benchmarking

133

Galapagos NV Annual Report 2021

CORPORATE GOVERNANCE

exercise indicated that in the biotechnology/pharmaceutical subsector, the “transatlantic” gap is
higher than in broader general industry and in the wider health sciences sector. The observed
gap in market pay levels between regional peer groups was attributable to long-term incentives;
in Europe,
long-term incentives were materially smaller. Galapagos’ pay-mix for all executive
functions was broadly in line with market practice observed within the U.S. peer group, while
in comparison to the European peer group it was more leveraged toward long-term incentives.
These findings were in line with and reinforced remuneration committee priorities for executive
compensation. The committee found the U.S. benchmark to be more relevant than that of
Europe given the majority of our competitors are based in the U.S., we have a significant number
of U.S. based shareholders whose views on remuneration are based on U.S. practices, and the
overall relevance of the U.S. market to the pharmaceutical industry.

Remuneration of supervisory board members

Remuneration structure components

The remuneration of supervisory board members consists of (i) a fixed annual cash amount, and
(ii) an equity-based component. The remuneration of the supervisory board members does not
contain a variable component, and hence no performance criteria apply to their remuneration.

(2) Ms. Bosley waived her equity-related remuneration for financial year 2021.

(3) Mr. O’Day and Dr. Higgins, both Gilead representatives, do not receive any remuneration for their mandate as supervisory

board members.

Cash remuneration

The supervisory board members receive a fixed annual cash amount, irrespective of the number
of board meetings that are held during the year. These board fees are paid in quarterly
installments at the end of each calendar quarter.

135

Galapagos NV Annual Report 2021

CORPORATE GOVERNANCE

For the financial year 2021 the chairman of the supervisory board received cash remuneration of
€100,000 and the other members €50,000 each. In addition, committee membership entitles the
supervisory board members to an additional €15,000 in cash and committee chairmanship to an
additional €20,000 in cash.

Equity based remuneration

In accordance with provision 7.6 of the 2020 Code, Galapagos also grants supervisory board
members an equivalent to remuneration in shares. During the financial year 2021, the
supervisory board members received the following additional cash compensation: for the
chairman of the supervisory board €100,000 and for the other members €50,000 each, in each
case subject to the requirement to use the net amount (after taxes) to acquire Galapagos shares.
One supervisory board member waived the equity-based remuneration for the financial year
2021. These share purchases took place on 15 December 2021 and resulted in the number of
shares identified in the table above. The shares that each supervisory board member so acquires
are to be held until at least one year after the supervisory board member leaves the supervisory
board and at least three years after the time of acquisition. These latter payments make up
the equivalent of an equity component of the supervisory board members’ remuneration, as
recommended by the 2020 Code.

As of 2020 Galapagos does not grant any subscription rights to supervisory board members
(non-executive directors).

Remuneration of management board members

Remuneration structure components

The remuneration of management board members consists of (i) fixed remuneration consisting
of base salary, pension and other benefits and (ii) variable remuneration consisting of a cash
bonus and the grant of restricted stock units (“RSUs”) and subscription rights (“SRs”). For the
variable part of the management board members’ remuneration, performance criteria apply.

Performance criteria and evaluation methods for
management board members

For 2021, the performance criteria considered in decision-making for cash bonuses and annual
RSU grants include the elements identified in the table below, whereby each of the corporate
objectives is further detailed in a clear and measurable way to enable robust evaluation by
the nomination and remuneration committee as well as the supervisory board. Our ambition
is to establish ourselves as a successful commercial stage biopharmaceutical company focused

136

Galapagos NV Annual Report 2021

CORPORATE GOVERNANCE

on the discovery, development and commercialization of novel medicines in areas of unmet
medical needs to improve the lives of people suffering from serious diseases.
In order to
achieve this long-term goal, we want to keep innovation in our research efforts while making
sound clinical progress year over year and maintaining a healthy cash position. In addition, our
corporate development and business goals aim to foster the growth of the company and the
creation of value for all shareholders, including via business development opportunities in our
core therapeutic areas. Finally, our commercial development goal is intended to continue to
build our filgotinib franchise throughout Europe, remain on track to complete the transition
of the full European commercial operations for filgotinib from Gilead to us and becoming a
commercially successful biopharmaceutical company which brings novel medicines to market
(subject to having obtained governmental approvals).

In terms of the individual performance evaluation, this is supported by the group’s performance
management system that assesses the performance of all employees (including management
board members) over the calendar year against a set of objectives determined at the start of the
year.

Finally, Galapagos’ policy is to grant a number of subscription rights each year based on a
consideration of each management board member’s role,
individual performance for the
performance year as well as individual impact on long-term value creation.

The nomination and remuneration committee is responsible for evaluating the management
board members’ performance in accordance with the principles set out above. The nomination
and remuneration committee is composed exclusively of non-executive directors and a majority
of its members qualify as independent supervisory board members. This helps prevent the

includes tax advisory fees.

(6) Management board member until 30 November 2021. His exit package is set out under section 'Severance clauses and payments'.

(7) Mr. Manto’s other components figure includes one-time compensation in relation to an adverse change in personal taxation basis. This change was

brought about by Galapagos’ decision for Mr Manto’s services to be provided under a management agreement with Galapagos from 1 January 2020, in
compliance with newly introduced Belgian Code and the introduction of the two-tier governance model and his appointment as mamagement board
member.

Fixed remuneration

The supervisory board, for the CEO upon recommendation of the nomination and remuneration
committee and for the other management board members upon proposals of the CEO, decided
that for the financial year 2021 each management board member received the base salary (gross
amount) as identified in the total remuneration table above. The fixed remuneration is a base
salary designed to fit responsibilities, relevant experience and competences, in line with market
rates for equivalent positions.

138

Galapagos NV Annual Report 2021

CORPORATE GOVERNANCE

Variable remuneration

Galapagos’ policy is to grant a number of
long-term incentives based on the individual
performance for the performance year while also considering individual impact on long-term
value creation. Bonuses consist both of a short-term cash component and a long-term RSU
component. Management board members were also offered subscription rights in 2021.

Under our remuneration policy, the CEO’s cash bonus can be maximum 75% of base salary. The
aggregate cash bonuses of the other members of the management board can be maximum 50%
of the aggregate base salaries. An equivalent number of RSUs will be granted to the CEO and the
other members of the management board under the RSU Annual Long-Term Incentive Plan.

(a) Short-term variable remuneration

The supervisory board determined an overall achievement of 75% (out of a maximum of 100%)
against the 2021 corporate objectives. In arriving at this determination, the supervisory board
considered that some of the objectives were not achieved, some had been achieved and some
overachieved. Highlights over 2021 included commercialization efforts to deliver Galapagos’ first
medicine to patients, the refocusing of our pipeline and rightsizing of our operations, and strong
financial discipline and operational excellence ensuring a long-term sustainable business.

The 75% corporate funding level is applicable to the wider Galapagos workforce for the corporate
component of their bonus funding, including the management board members. The supervisory
board, for the CEO upon recommendation of the nomination and remuneration committee and
for the other management board members upon proposals of the CEO, considered this level of
funding, as applied to the wider workforce, together with individual performance of management
board members in order to determine the individual cash bonus outcomes for 2021 set out in
the total remuneration table above: Mr. Onno van de Stolpe (€360,000; 56.63% of 2021 base
salary), Mr. Bart Filius (€215,906; 43.18% of 2021 base salary), Dr. Andre Hoekema (€92,531;
24.35% of 2021 base salary), Dr. Walid Abi-Saab (€154,219; 36.29% of 2021 base salary) and
Mr. Michele Manto (€154,219; 45.36% of 2021 base salary). These 2021 cash bonuses will be
paid in April 2022. With the exception of the retiring CEO, each of the management board
members will be granted an equivalent number of RSUs under the 2022 RSU Annual Long-Term
Incentive Plan as long-term variable remuneration. Galapagos applied a maximum corporate
funding (100%) for the determination of Dr. Wigerinck's bonus and Dr. Wigerinck received a pro
rata maximum cash bonus for 2021 (€194,792; 45.83% of 2021 base salary). His bonus has been
paid out in December 2021 and he will not be entitled to any subsequent RSU grant.

(b) Long-term variable remuneration

In 2021 the management board members were offered new subscription rights under
Subscription Right Plan 2021 BE and each accepted all subscription rights granted as per the
following: Mr. Onno van de Stolpe: 85,000 subscription rights, Mr. Bart Filius: 50,000 subscription
rights, each of Dr. Piet Wigerinck and Dr. Walid Abi-Saab: 40,000 subscription rights and each
of Dr. Andre Hoekema and Mr. Michele Manto: 30,000 subscription rights. Further reference is
made to the Equity components of the remuneration section, which contains, among others, a
description of the 2021 grant of subscription rights.

The total remuneration table above sets forth the value of the number of RSUs vested and
paid out in 2021 for each management board member. Each RSU represents the right to

receive, at Galapagos’ discretion, one Galapagos share or a payment in cash of an amount
equivalent to the volume-weighted average price of the Galapagos share on Euronext Brussels
over the 30-calendar day period preceding the relevant vesting date. During 2021, there were
RSU vestings under three different RSU plans: Plan 2019.II, Plan 2019.III and Plan 2020.II. The pay-
outs to the management board members occurred accordingly and the aggregate amounts are
set forth in the total remuneration table above. Reference is made to the Equity components of
the remuneration section.

For a description of the RSU grants to the management board members in 2021, reference is
made to the Equity components of the remuneration section. This section also sets out the
main characteristics of the different RSU plans issued by Galapagos to its management board
members in 2019, 2020 and 2021.

The 50% deferred part of the bonus awarded and relating to the financial year 2018 was entirely
forfeited and not paid out in 2021 as a result of the share performance of Galapagos NV’s share
over the period 2018 – 2021 relative to the Next Biotech Index (which tracks Euronext-listed
biotech companies) as per the provisions of the Senior Management Bonus Scheme.

Pension and other components

insurance programs (covering life insurance, disability, travel

In addition, the management board members enjoy a number of benefits such as a retirement
plan,
insurance and health),
company cars and the provision of tax advisory services. The aforementioned retirement plan is
set up as a defined contribution arrangement and is in line with market practice in Belgium. The
pension and other components of the remuneration of each management board member are
summarized in the total remuneration table above.

Subscription rights awarded, exercised or expired

In 2021, we issued three subscription right plans for the benefit of employees of the group
and of management board members: Subscription Right Plan 2021 BE, Subscription Right Plan
2021 RMV and Subscription Right Plan 2021 ROW. The management board members were
offered new subscription rights under Subscription Right Plan 2021 BE, subject to acceptance.
Subscription rights is the new term for instruments formerly referred to as “warrants” under
the new Belgian Companies Code. The final number of accepted subscription rights under
Subscription Right Plan 2021 BE was enacted by notary deeds of 2 July 2021 and 18 August 2021.
The table below sets forth the numbers of subscription rights offered and accepted by each
management board member in 2021 under Subscription Right Plan 2021 BE.

The main characteristics of the subscription right plans offered to the management board
members are as follows:

The subscription rights are offered for no consideration;

The subscription rights typically have a lifetime of eight years and a vesting period of three
years after the year of grant;

Good and bad leaver rules apply in case of termination prior to the end of the vesting period;
and

The subscription rights are not transferable.

Under Subscription Right Plan 2021 BE, the subscription rights have a lifetime of eight years
and an exercise price of €64.76. Each subscription right gives the right to subscribe for one
new Galapagos share. For all the beneficiaries under the Subscription Right Plan 2021 BE, the
subscription rights vest only and fully on the first day of the fourth calendar year following
the calendar year in which the grant was made. The subscription rights can in principle not
be exercised prior to 1 January 2025. The table below sets forth the main characteristics for
subscription right plans issued during previous years.

As from 1 January 2020, Galapagos no longer grants any subscription rights to supervisory board
members, taking into account the stricter rules of the Belgian Companies Code and provision 7.6
of the 2020 Code, which stipulates that non-executive directors should not be entitled to receive
stock options. Prior to 2020, supervisory board members were granted subscription rights and
hence the table below also contains disclosures for supervisory board members.

No subscription rights expired for management board or supervisory board members in 2021.

The table below sets forth the subscription rights outstanding and exercisable per
31 December 2021 for
the
subscription rights awarded to the management board members during 2021 and exercised by
the management board or supervisory board members in 2021, including for our former CSO
Dr. Wigerinck:

RSUs offered to, vested or expired for the management board
members

In 2021, the management board were offered new RSUs under 2021 RSU Annual Long-Term
Incentive Plan and the 2021 RSU Retention Plan, subject to acceptance. The members of the
management board accepted all RSUs offered to them, except for two management board
members who did not accept their grant under the 2021 RSU Annual Long-Term Incentive Plan.
The grant under the 2021 RSU Annual Long-Term Incentive Plan is the long-term portion of the
bonus for 2020 and this RSU grant will vest in full three years after the offer date. The grant under
the 2021 RSU Retention Plan has a four-year vesting period, with 25% vesting each year and a
first vesting date on 1 May 2022. The RSUs are not transferable. The table below sets forth the
total number of RSUs offered to each management board member during 2021: Mr. Onno van

149

Galapagos NV Annual Report 2021

CORPORATE GOVERNANCE

de Stolpe: 63,830 RSUs, Mr. Bart Filius: 62,730 RSUs, Dr. Piet Wigerinck: 835 RSUs, Dr. Walid Abi-
Saab: 44,038 RSUs, Dr. Andre Hoekema: 52,312 RSUs and Mr. Michele Manto: 31,694 RSUs.

The main characteristics of the RSU plans for the management board members are as follows:

The RSUs are offered for no consideration;

Three or four year vesting periods apply, as set forth per plan in the table below;

In case of termination of service before the vesting date, forfeiture rules apply.

Each RSU represents the right to receive, at Galapagos’ discretion, one Galapagos share or a payment
in cash of an amount equivalent to the volume-weighted average price of the Galapagos share on
Euronext Brussels over the 30-calendar day period preceding the relevant vesting date. However, in
respect of management board members, any vesting prior to the third anniversary of the offer date
will always give rise to a payment in cash rather than a delivery of shares as an incentive.

No RSUs expired during financial year 2021. The table below sets forth the main characteristics
of RSU plans issued to the management board members in 2019, 2020 and 2021, the number
of RSUs awarded to each management board member under the respective RSU Plan, and the
number of RSUs vested and paid out to each management board member during 2021, including
for our former CSO, Dr. Wigerinck:

(1) Dr. Andre Hoekema did not accept his offer under the 2021.I RSU Plan.

(2) Upon substantiated recommendation of the remuneration and nomination committee, the supervisory board approved a deviation of the vesting

rules under the RSU Plan 2021.IV. The second vesting of 25% of the RSU grant under the aforementioned plan (corresponding with 12,858 RSUs) will
occur earlier than under the normal plan rules.

(3) Dr. Piet Wigerinck did not accept his offer under the 2021.I RSU Plan.

Pursuant to the terms and conditions of the RSU plans all unvested RSUs of Dr. Piet Wigerinck,
as set out in the table above, became null and void on his termination date, 30 November
2021. Reference is made to the one-time lump-sum payment as compensation for his unvested
outstanding RSUs as set out in the section on severance payments for departing management
board members.

In 2022, as part of the management board’s long-term variable remuneration, a number of
RSUs equivalent to the 2021 short-term cash bonuses (based on the average share price of the
Galapagos share on Euronext Amsterdam during the month of April 2022) will be granted to
the management board members under the 2022 RSU Annual Long-Term Incentive Plan (i.e. the
long-term portion of the bonus for 2021), except to the retiring CEO.

(1) The directors' remuneration overview contains for each individual management board and supervisory board member two separate rows, whereby
the first row sets out their cash remuneration, being the annual base salary, cash bonus and (if any) exceptional bonus, to enable the comparison
with the average remuneration of employees on FTE basis, and the second row sets out their total remuneration, including equity-related
remuneration such as granted SRs and vested RSUs.

(2) The first row shows the cash remuneration of each management board member, being the annual base salary, cash bonus and (if any) exceptional

bonus.

(3) The second row shows the total remuneration of each management board member, including equity-based remuneration such as RSUs vested and
subscription rights granted during the year. The value of the subscription rights is calculated by comparing the exercise price of the subscription
right plan with the average share price as quoted on Euronext Brussels and Amsterdam during the respective financial year. For example, for
financial year 2021 the exercise price of the Subscription Right Plan 2021 BE is compared with the average share price as quoted on Euronext
Brussels and Amsterdam during the financial year 2021.

(4) Management board member until 30 November 2021. Both rows set out his remuneration from 1 January 2021 until 30 November 2021, excluding

his severance package.

(5) Management board member as of 1 January 2017. The total remuneration for FY 2017, as set out on the second row for FY 2017, includes Dr. Walid

Abi-Saab's hiring grant of subscription rights under Warrant Plan 2016 (B).

(11) Prior to the financial year ended 31 December 2021, R&D expenditure presented on this line is reflecting the total Group related expenditure
including Fidelta, our fee-for-service business sold to Selvita on 4 January 2021, classified as discontinued operations in our 2020 consolidated
financial statements. R&D expenditure of our continuing operations presented in our consolidated financial statement were €523,667 thousands for
the financial year ended 31 December 2020, €420,090 thousands for the financial year ended 31 December 2019 and €316,222 thousands for the
financial year ended 31 December 2018.

(12) Cash position on 31 December 2020 included €7,884 thousands of cash held in Fidelta and classified as assets held for sale in our 2020 consolidated

financial statements.

(13) The number of employees per 31 December includes employees and insourced personnel (external contractors). At 31 December 2020, the number

of employees included 185 employees of our fee for service activity Fidelta, which was sold to Selvita on 4 January 2021.

(14) The average remuneration of employees is calculated on FTE basis, excluding trainees and internships, for employees employed for the full
applicable financial year. It takes into account the employees' base salary, annual cash bonus and (if any) exceptional cash bonus during the
respective financial year. During 2019, all Galapagos' employees received an exceptional bonus as a result of the Gilead transaction. Annual cash
bonuses are included in the year upon which performance is based and not in the year in which they are paid. Due to the timing of the 2021 year-
end process, the actual annual figures for employees had not been finalized by the date of this report. Therefore, 2021 annual bonus figures
represent target figures multiplied by the applicable approved organizational bonus funding scores, being the company’s best estimate of actual
bonus outcomes.

Ratio between the highest and lowest remuneration

The ratio between the highest and lowest remuneration at Galapagos during financial year 2021
is: 1:33.

The ratio is calculated on the basis of the lowest FTE pay per 31 December 2021, excluding
trainees and internships. The remuneration which has been taken into account in this exercise
includes the annual base salary, annual cash bonus and (if any) exceptional bonus; annual cash
bonus is included in the year upon which performance is based and not in the year in which
it is paid. Due to the timing of the 2021 year-end process, the actual annual bonus figures for
employees below the management board level had not been finalized by the date of this report.
Therefore, target figures for these employees were used, multiplied by the applicable approved
organizational bonus funding scores, being the company’s best estimate of 2021 actual bonus
outcomes.

Minimum share ownership

From the financial year 2020, the remuneration policy has set a minimum threshold of shares
to be held at any time by the CEO to the number of shares equivalent to one year of the CEO’s
annual base salary and by the other management board members to the number of shares
equivalent to six months’ of the relevant management board member’s annual base salary.
Thresholds will be re-calculated on an annual basis and need to be reached within four years.

Severance clauses and payments

Severance payments for departing management board
members

In 2021 Dr. Piet Wigerinck, CSO and management board member,
left Galapagos. Upon
substantiated recommendation of the nomination and remuneration committee, the supervisory
board approved the following severance package: (i) a severance compensation equal to six
(ii) a one-time lump-sum payment of €553,766 as
months of remuneration,
compensation for his unvested outstanding RSUs on his termination date and (iii) a non-compete
of 12 months after the termination date in consideration of the payment by Galapagos of a
monthly fee of €35,416.66 as stipulated in his management contract, except if Galapagos waives
enforcement of the non-compete. Galapagos also paid Dr. Wigerinck’s 2021 pro rata (11/12)
maximum cash bonus.

i.e. €212,500,

Dr. Wigerinck will not receive the long-term portion of the 2021 bonus, being a number of RSUs
equivalent to the 2021 short-term cash bonus. He qualifies as a good leaver under the terms and
conditions of the subscription right plans and this is not part of his severance package.

On 30 August 2021, Galapagos announced the planned retirement of its CEO Onno van de
Stolpe. After a transition period during which the retiring CEO will hand over his activities,
Stoffels IMC BV, permanently represented by Dr. Paul Stoffels will fully take over as CEO effective
1 April 2022. Upon substantiated recommendation of
the nomination and remuneration
committee, the supervisory board approved the following retirement package: a non-compete of
12 months against the payment of a monthly fee of €150,000 by Galapagos, except if Galapagos
waives enforcement of the non-compete. Until 31 October 2022, Onno van de Stolpe will execute
a purely advisory role as advisory member of the management board, for which he will continue
including entitlement to RSU pay-outs until the
to receive his base salary and benefits,
aforementioned date. In 2022, Onno van de Stolpe will not be eligible to 2022 performance
variable remuneration,
i.e. a cash bonus and the long-term portion of the bonus for 2021.
Furthermore, he will not be eligible for any equity grants (RSUs and subscription rights) in 2022.
He qualifies as a good leaver under the terms and conditions of the subscription right plans and
this is not part of his severance package.

Claw-back right of Galapagos relating to variable
remuneration

As from financial year 2020, contractual provisions apply to each management board member
to ensure that Galapagos has the right to have each management board member forfeit any
unvested RSUs, deferred portions of previous cash bonuses or unvested subscription rights in
the event of a restatement of the financial statements that has a material negative effect on
Galapagos or a material breach of our Code of Conduct and Ethics.

During the financial year 2021 no claw-back events occurred.

158

Galapagos NV Annual Report 2021

CORPORATE GOVERNANCE

The 2021 RSU plans and 2021 subscription right plans contain bad leaver provisions that can
result in forfeiture of any unvested RSU and/or subscription right grants in case the beneficiary
leaves Galapagos prior to the relevant vesting date.

Deviations from the remuneration policy

Galapagos’ remuneration policy sets out that the supervisory board may decide to deviate
from any items of the policy if necessary to serve the long-term interests and sustainability
of Galapagos. Any such deviation must be discussed at the nomination and remuneration
committee, which will provide a substantiated recommendation to the supervisory board.

During the financial year 2021, the supervisory board decided to deviate from the Galapagos’
remuneration policy, upon substantiated recommendation of the nomination and remuneration
committee, with the intention of serving the long-term interests and sustainability of Galapagos
and in view of a successful and thorough implementation of the leadership transition whilst
guaranteeing continuity, at three occasions:

On 22 June 2021, a termination package for Dr. Wigerinck has been approved, being,
in
addition to a 6 months’ severance compensation of €212,500, a one-time lump-sum payment
of €553,766 for his unvested outstanding RSUs at his termination date and a non-compete
of 12 months in consideration of the payment by Galapagos of a monthly fee €35,416.66
as stipulated in his management contract. However, his total termination package does not
exceed his annual remuneration for the financial year 2020 (for which shareholder approval
would have been required);

On 26 August 2021, a retirement package for Mr. van de Stolpe has been approved, being a
non-compete of 12 months in consideration of the payment by Galapagos of a monthly fee of
€150,000. However, his total retirement package does not exceed his annual remuneration
for the financial year 2020 (for which shareholder approval would have been required); and

On 20 September 2021, a one-time deviation of the vesting rules of the RSU Plan 2021.IV
for the RSU grant under the aforementioned plan to Dr. Hoekema has been approved. The
second vesting of 25% (corresponding with 12,858 RSUs) will occur earlier than under the
normal plan rules.

Conflict of interests and related parties

We consider that Gilead became a related party of Galapagos in 2019 because of Gilead’s then
25.84% shareholding (25.49% on 31 December 2021) in Galapagos and the fact that Gilead is
entitled to propose two candidates to be appointed to our supervisory board under the share
subscription agreement.

On 6 September 2021, we entered into a related party transaction with Gilead within the
meaning of article 7:116 of the Belgian Companies Code, by agreeing to transfer the sponsorship
of and the operational and financial responsibility for the DIVERSITY clinical study, evaluating
filgotinib in Crohn’s Disease, and its long-term extension study, from Gilead to us. Daniel O’Day
and Linda Higgins only participated in the discussion among the supervisory board prior to the
deliberation and resolutions in relation to the DIVERSITY Letter Agreement, and then recused
themselves from the supervisory board meeting held on 4 September 2021 regarding this
related party transaction, since they are representatives of Gilead. The remaining supervisory
board members considered that the related-party transaction’s approval mechanism didn’t need
to be applied, since the value of the DIVERSITY Letter Agreement is less than 1% of the Company’s
consolidated net equity (based on the consolidated interim financial statements of Galapagos
for the six months ended 30 June 2021) and since Galapagos is therefore able to rely on the
materiality exemption set out in article 7:116, § 1, 2° of the Belgian Companies Code. A more
detailed explanation of our transactions with Gilead in 2021 can be found in the section titled
Agreements with major Galapagos NV shareholders. We further refer to note 31.

In the event of a transaction where a supervisory board member’s interest conflicts with the
interest of Galapagos NV, the board member shall notify the supervisory board in advance of
the conflict and will act in accordance with the relevant rules of the Belgian Companies Code
(i.e. article 7:115 of the Belgian Companies Code for supervisory board members). In the event
of a transaction where a management board member’s interest conflicts with the interest of
Galapagos NV, the management board shall refer the decision regarding such transaction to the
supervisory board.

In addition, Galapagos’ Corporate Governance Charter and Galapagos’ Related Person
Transaction Policy contain procedures for transactions between Galapagos and its supervisory
board members, management board members, major shareholders or any of their immediate
family members and affiliates. Without prejudice to the procedure defined in articles 7:115
and 7:117 of the Belgian Companies Code, these policies provide that all transactions between
Galapagos and its supervisory board members, management board members or
its
representatives need the approval of the audit committee and the supervisory board, which
approval can only be provided for transactions at normal market conditions. Moreover, conflicts
of interest, even in the event they are not a conflict of interest within the meaning of articles 7:115
and 7:117 of the Belgian Companies Code, are enacted in the meeting minutes, and the relevant
board member cannot participate in the voting.

160

Galapagos NV Annual Report 2021

CORPORATE GOVERNANCE

In 2021, the following conflict of interests between Galapagos NV and a director within the
meaning of article 7:115 of the Belgian Companies Code was noted:

in a meeting of the supervisory board held on 4 September 2021, the following was reported
in accordance with article 7:115 of the Belgian Companies Code in connection with the
proposed DIVERSITY Letter Agreement: the chairman declared that Daniel O’Day and Linda
Higgins had informed him that, since they are representatives of Gilead, they might have a
conflict of interest in relation to the resolutions to be passed by the supervisory board in
relation to the DIVERSITY Letter Agreement. Accordingly, Daniel O’Day and Linda Higgins only
participated in the discussion among the supervisory board prior to the deliberation and
resolutions in relation to the DIVERSITY Letter Agreement, and then recused themselves for
the meeting.

Code of Business Conduct and Ethics

In 2021, we have established a new Code of Business Conduct and Ethics to ensure that
our supervisory board members, management board members and employees are making
ethical and legal decisions when conducting Galapagos’ business and performing their day-
to-day duties. We expect our supervisory board members, management board members and
employees to conduct business with integrity, ethics and respect for human rights. We expect
them to turn away from conflicts of interest, corruption and fraud. To this end, we give trainings
on this new Code to our employees, including our subsidiaries’ employees. So far, since the
launch of our new Code of Business Conduct and Ethics, 93.5% of our employees have
completed the training.

The new Code of Business Conduct and Ethics is available at https://www.glpg.com/
governance-information.

One breach of our Code of Business Conduct and Ethics was reported to the audit committee in
2021.

Notes to the consolidated financial
statements

1. General information

Galapagos NV is a limited liability company incorporated in Belgium and has its registered office
at Generaal De Wittelaan L11 A3, 2800 Mechelen, Belgium. In the notes to the consolidated
financial statements, references to “we”, “us,” “the group” or “Galapagos” include Galapagos NV
together with its subsidiaries.

We are an integrated biopharmaceutical company active in the discovery, development, and
commercialization of medicines with novel modes of action, several of which are currently in
clinical development in multiple diseases with high unmet medical need. Our highly flexible
discovery platform is applicable across many therapeutic areas.

Having achieved approval in the European Union and Great Britain for our first ever medicine
in RA and UC, we remain highly committed to progressing our pipeline of drug candidates to
address unmet medical needs and improve the lives of millions.

We devote substantially all of our resources to our drug discovery efforts from target discovery
through clinical development, and to our commercialization efforts for filgotinib in Europe.

The components of the operating result presented in the financial statements include the
following companies: Galapagos NV, Galapagos Biopharma Belgium BV, Galapagos Real Estate
Belgium BV (Mechelen, Belgium); Galapagos SASU (Romainville, France); Galapagos B.V.,
Galapagos Biopharma Netherlands B.V. and Galapagos Real Estate Netherlands B.V. (Leiden,
the Netherlands); Galapagos, Inc. and its subsidiary Xenometrix, Inc. (United States); Galapagos
GmbH (Basel, Switzerland); Galapagos Biotech Ltd (Cambridge, UK); Galapagos Biopharma
Germany GmbH (München, Germany); Galapagos Biopharma Spain S.L.U.
(Madrid, Spain),
Galapagos Biopharma Italy S.r.l. (Milan, Italy), Galapagos Biopharma Sweden AB (Stockholm,
Sweden), Galapagos Biopharma Norway AS (Oslo, Norway), Galapagos Biopharma Finland Oy
(Helsinki, Finland), Galapagos Biopharma Denmark ApS (Copenhagen, Denmark), Galapagos

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.

2. Summary of significant transaction

On 14 July 2019 we and Gilead announced that we entered into a 10-year global research
and development collaboration. Through this agreement, Gilead gained exclusive access to our
innovative portfolio of compounds, including clinical and preclinical programs and a proven drug
discovery platform. At inception of this collaboration in 2019, we received an upfront payment
€3,569.8 million ($3.95 billion) and a €960.1 million ($1.1 billion) equity investment from Gilead.

On the closing date of the transaction (23 August 2019) we concluded that the upfront payment
implicitly included a premium for the future issuance of warrant A and initial and subsequent warrant
B. The expected value of the warrants to be issued is treated as a contract liability (“warrant issuance
liability”) and reduces the transaction price until approval date of the issuance of the underlying
warrants. As from approval date, the allocation of the upfront payment to the respective warrant
becomes fixed and future changes in the fair value of the respective warrant are recognized in profit
or loss. As such, the part of the upfront payment allocated to the warrant A and initial warrant B
reflects the fair value of these financial liabilities at the warrant approval date (22 October 2019).

On 6 November 2019 Gilead exercised warrant A, which resulted in an additional equity
investment of €368.0 million.

Subsequent warrant B is still subject to approval by an extraordinary general meeting of
shareholders and is therefore still presented as warrant issuance liability in our deferred income
(we refer to note 25 for more information). The value allocated to the subsequent warrant B
reflects the fair value of the underlying liability on 31 December 2020 and 31 December 2021.
On 31 December 2021 the value of the subsequent warrant B decreased to €2.4 million, driven
by the decrease of our share price, and of the implied volatility in 2021.

At inception of this collaboration, we identified the following three performance obligations: (i) the
transfer of an extended license on GLPG1690, (ii) the granting of exclusive access to our drug
discovery platform (i.e. the IP, technology, expertise and capabilities) during the collaboration period
and exclusive option rights on our current and future clinical programs after Phase 2 (or, in certain
circumstances, the first Phase 3 study) outside Europe and (iii) an increased cost share from 20/
80 to 50/50 on the global development activities of filgotinib, as a result of the revised license and
collaboration agreement.

As part of the collaboration, Gilead also received option rights for GLPG1972, a Phase 2b
candidate for osteoarthritis, in the United States. In November 2020, Gilead however declined to
exercise its option for GLPG1972.

Since 22 October 2019, Gilead has had two representatives on the supervisory board of
Galapagos (Daniel O’Day and Linda Higgins).

174

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

In Q4 2020, Gilead decided not to pursue FDA approval of the RA indication for filgotinib in the
U.S. as a result of Complete Response Letter (CRL) from the Food and Drug Administration (FDA).
Due to this, in December 2020 Gilead and we agreed to amend our existing collaboration for the
commercialization and development of filgotinib. This resulted in the execution of the Transition
and Amendment Agreement of 3 April 2021 and the Second Amended and Restated license and
Collaboration Agreement of 24 December 2021, effective as of 1 January 2022.

In September 2021 we agreed together with Gilead to also take over the sponsorship of and
operational and financial responsibility for the ongoing DIVERSITY clinical study, evaluating
filgotinib in CD, and its long-term extension study. We intend to complete the transfer of the
DIVERSITY clinical study no later than 30 June 2022. From 1 April 2022, we will also be solely
responsible for all development costs for the DIVERSITY clinical study.

Gilead remains responsible for commercial activities outside of Europe.

These modifications to the collaboration with Gilead did not result in the creation of new
performance obligations, and only the performance obligation related to the development
activities for filgotinib has been reassessed.

We retain the following three performance obligations, of which the first one was satisfied
completely in 2019; (i) the transfer of an extended license on GLPG1690, (ii) the granting of
exclusive access to our drug discovery platform (i.e. the IP, technology, expertise and capabilities)
during the collaboration period and exclusive option rights on our current and future clinical
programs after Phase 2 (or, in certain circumstances, the first Phase 3 study) outside Europe and
(iii) an increased cost share from 20/80 to 50/50 to 100/0 (for certain agreed activities (Group A
activities, as defined below)) on the global development activities of filgotinib, until we complete
the remaining development activities.

We refer to the critical accounting judgments and key sources of estimation uncertainty section
(note 4) explaining critical judgments and estimates in applying accounting policies.

Terms of the collaboration

We will fund and lead all discovery and development autonomously until the end of Phase 2. After the
completion of a qualifying Phase 2 study (or, in certain circumstances, the first Phase 3 study), Gilead
will have the option to acquire a license to the compound outside Europe. If the option is exercised,
we and Gilead will co-develop the compound and share costs equally. Gilead will maintain option
rights to our programs through the 10-year term of the collaboration. This term can be extended
for up to an additional three years thereafter for those programs, if any, that have entered clinical
development prior to the end of the collaboration term. In addition, a final term extension can be
granted in certain circumstances. Development of GLPG1690 was discontinued in February 2021.

For GLPG1972, after the completion of the ongoing Phase 2b study in osteoarthritis, Gilead had
the option to pay a $250 million fee to license the compound in the United States but declined
to exercise its option in November 2020.

175

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

For all other programs resulting from the collaboration, Gilead will make a $150 million opt-in
payment per program and will owe no subsequent milestones. We will receive tiered royalties
ranging from 20% – 24% on net sales of all our products licensed by Gilead in all countries
outside Europe as part of the agreement.

Revised filgotinib collaboration

Under the revised agreement of December 2020, we assume all development, manufacturing,
commercialization and certain other rights for filgotinib in Europe, providing the opportunity to
build a commercial presence on an accelerated timeline. The transfer is subject to applicable
local legal, regulatory and consultation requirements. Most activities have been transferred as
of 31 December 2021 and the parties intend to complete the transition by 31 December 2022.
Beginning on 1 January 2021, we bear the future development costs for certain studies (defined
as “Group A activities”), in lieu of the equal cost split contemplated by the previous agreement.
These studies initially included the DARWIN3, FINCH4, FILOSOPHY, and Phase 4 studies and
registries in RA, MANTA and MANTA-RAy, the PENGUIN1 and 2 and EQUATOR2 studies in PsA, the
SEALION1 and 2 studies in AS, the HUMBOLDT study in uveitis in addition to other clinical and
non-clinical expenses supporting these studies and support for any investigator sponsored trials
in non-IBD conditions and non-clinical costs on all current trials. The DIVERSITY study has been
added to the “Group A activities” in September 2021. The existing 50/50 global development
cost sharing arrangement will continue for the following studies (defined as “Group B activities”):
SELECTION and its long-term extension study (LTE) in UC, DIVERGENCE 1 and 2 and their
LTEs and support for Phase 4 studies and registries in Crohn’s disease, pediatric studies and
their LTEs in RA, UC and Crohn’s disease, and support for investigator sponsored trials in
IBD. All commercial economics on filgotinib in Europe will transfer to us as of 1 January 2022,
subject to payment of tiered royalties of 8% to 15% of net sales in Europe to Gilead, starting
in 2024. In addition, if the European Medicines Agency grants regulatory approval of filgotinib
for the treatment of CD based on data from the DIVERSITY trial, then royalties payable by us to
Gilead will be reduced by 30% across all filgotinib indications and will become 5.6% to 10.5%
of net sales in Europe. In connection with the amendments to the existing arrangement for
the commercialization and development of filgotinib, Gilead has agreed to irrevocably pay us
€160 million, which is split between a €110 million payment received in 2021 and a €50 million
payment to be received in 2022 and is subject to certain adjustments for higher than budgeted
development costs. Upon completion of the DIVERSITY study transfer in 2022, Gilead will make
a one-time payment of $15 million to us in consideration for assuming responsibility for the
DIVERSITY clinical study. In addition, we will no longer be eligible to receive any future milestone
payments relating to filgotinib in Europe. Other terms of the original license agreement remain
in effect, including the remaining $295 million in development and regulatory milestones, sales-
based milestone payments of up to $600 million and tiered royalties ranging from 20% – 30%
payable in territories outside Europe (whereas before it was applicable for all countries outside of
Belgium, France, Germany, Italy, Luxembourg, the Netherlands, Spain and the United Kingdom).

In addition, we achieved two regulatory approval milestones in 2020 totaling $105 million. No
regulatory approval milestones were achieved during 2021.

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

Terms of the equity investment

As part of the research and development collaboration of 2019 Gilead also entered into a
share subscription agreement with us. Gilead’s equity investment consisted of a subscription
for new Galapagos shares at a price of €140.59 per share, representing on 14 July 2019 a
20% premium to Galapagos’ 30-day, volume-weighted average price. This equity subscription
took place at closing of the transaction, on 23 August 2019 and increased Gilead’s stake in
Galapagos from approximately 12.3% to 22.04% of the then issued and outstanding shares in
Galapagos. In addition, the extraordinary general meeting of shareholders of 22 October 2019
approved the issuance of warrant A and initial warrant B allowing Gilead to further increase its
ownership of Galapagos to up to 29.9% of the company’s issued and outstanding shares. The
initial warrant B has a term of five years and an exercise price per share equal to the greater
of (i) 120% multiplied by the arithmetic mean of the 30-day daily volume weighted average
trading price of Galapagos’ shares as traded on Euronext Brussels and Euronext Amsterdam,
and (ii) €140.59. Subsequent warrant B is still subject to approval by an extraordinary general
meeting of shareholders. This extraordinary general meeting of shareholders shall take place
between 57 and 59 months after the closing of the subscription agreement (23 August 2019)
and this warrant will have substantially similar terms, including as to exercise price, to the initial
warrant B. The agreement also includes a 10-year standstill restricting Gilead’s ability to propose
a business combination with or acquisition of Galapagos or increase its stake in Galapagos
beyond 29.9% of the company’s issued and outstanding shares, subject to limited exceptions.
On 6 November 2019, Gilead exercised warrant A and increased its ownership in Galapagos to
25.10% of the then outstanding shares. Warrant A expired in October 2020. Gilead’s ownership
amounted to 25.49% at 31 December 2021.

3. Significant accounting policies

Our principal accounting policies are summarized below.

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

177

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

Standards and interpretations published, but not yet
applicable for the annual period beginning on 1 January 2021

A number of new standards are effective for annual periods beginning on or after 1 January 2022
with earlier adoption permitted. However we have not early adopted new or amended standards
in preparing our consolidated financial statements. We are currently still assessing the impact of
these new accounting standards and amendments that are not yet effective but we expect no
standard to have a material impact on our financial statements in the period of initial application.

The following amendments are effective for the period beginning 1 January 2022:

Onerous Contracts – Cost of Fulfilling a Contract (Amendments to IAS 37);

Property, Plant and Equipment: Proceeds before Intended Use (Amendments to IAS 16);

Annual Improvements to IFRS Standards 2018-2020 (Amendments to IFRS 1, IFRS 9, IFRS 16
and IAS 41); and

References to Conceptual Framework (Amendments to IFRS 3).

The following amendments are effective for the period beginning 1 January 2023:

Disclosure of Accounting Policies (Amendments to IAS 1 and IFRS Practice Statement 2);

Definition of Accounting Estimates (Amendments to IAS 8);

Deferred Tax Related to Assets and Liabilities arising from a Single Transaction (Amendments
to IAS 12); and

IFRS 17 Insurance Contracts and Amendments to IFRS 17.

Consolidated reporting

The consolidated financial statements comprise the financial statements of Galapagos NV and
entities controlled by Galapagos NV. Control is achieved where Galapagos NV has the power
to direct the relevant activities of another entity so as to obtain benefits from its activities. The
results of subsidiaries are included in the income statement and statement of comprehensive
income from the effective date of acquisition up to the date when control ceases to exist.
Where necessary, adjustments are made to the financial statements of subsidiaries to ensure
consistency with our accounting policies. All
income and
expenses are eliminated when preparing the consolidated financial statements.

intra-group transactions, balances,

Intangible assets

Expenditure on research activities is recognized as an expense in the period in which it is
incurred.

An internally generated intangible asset arising from our development activities is recognized
only if all of the following conditions are met:

Technically feasible to complete the intangible asset so that it will be available for use or sale

We have the intention to complete the intangible assets and use or sell it

We have the ability to use or sell the intangible assets

178

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

The intangible asset will generate probable future economic benefits, or indicate the
existence of a market

Adequate technical, financial and other resources to complete the development are available

We are able to measure reliably the expenditure attributable to the intangible asset during
its development.

(i) Internally generated intangible assets

The amount capitalized as internally generated intangible assets is the sum of the development
costs incurred as of the date that the asset meets the conditions described above. Because of
risks and uncertainties inherent to the regulatory authorizations and to the development process
itself, management estimates that the conditions for capitalization are not met until we obtain
regulatory approval from the competent authorities.

Currently we recognize all development costs as an expense in the period in which they are
incurred, even for approved products because they do not generate separately identifiable
incremental future economic benefits that can be reliably measured.

(ii) Licenses, patents & know-how

Acquired in-process research and development obtained through in-licensing agreements,
business combinations, collaboration agreements or separate acquisitions are capitalized as an
intangible asset provided that they are separately identifiable, controlled by us and expected
to provide economic benefits. As the probability criterion in IAS 38 is always considered to
be satisfied for separately acquired research and development assets, upfront and milestone
payments to third parties for products or compounds for which regulatory approval has not yet
been obtained are recognized as intangible assets. We consider such intangible assets as not
yet available for use until the moment that the underlying asset is approved and commercially
is approved for
launched. Amortization will commence when the underlying asset
commercialization and the asset will be amortized over its useful life.

Licenses, patents and know-how will be amortized over their useful life (generally between 5 and
20 years), using the straight-line method.

Intangible assets may also consist of upfront fees paid to third party institutions in exchange for
an option to negotiate a license to any of the third party’s rights in technology resulting from the
collaboration. The upfront fee paid in exchange for this option is capitalized as intangible asset
and amortized over the expected duration of the option.

In the event an asset has an indefinite life, this fact is disclosed along with the reasons for being
deemed to have an indefinite life. Intangible assets with an indefinite useful life and intangible
assets which are not yet available for use are tested for impairment annually, and whenever there
is an indication that the asset might be impaired.

(iii) Software

Acquired software is recognized at cost less accumulated amortization and any impairment loss.
Amortization is recognized so as to write off the cost of assets over their useful lives (generally
between 3 and 5 years), using the straight-line method.

179

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

(iv) Contract costs

Contract costs are those costs we incur to obtain a contract with a customer that we would not
have incurred if the contract has not been obtained and are capitalized as intangible assets only
if they are expected to be recoverable. Capitalized contract costs are amortized on a systematic
basis that reflects the pattern of transfer of the related promised goods or services to the
customer. Costs that we would have incurred regardless of whether the contract is obtained or
those costs that are not directly related to obtaining a contract would not be capitalized.

Property, plant and equipment

Property, plant and equipment are recognized at cost less accumulated depreciation and any
impairment loss.

Depreciation of an asset begins when it is available for use, ie when it is in the location and
condition necessary for it to be capable of operating in the manner intended by management.

Depreciation is recognized so as to write off the cost of assets over their useful lives, using the
straight-line method, on the following bases:

Installation & machinery: 3 – 15 years

Furniture, fixtures & vehicles: 4 – 10 years

Leasehold improvements are depreciated over 3 - 10 years, being the term of the lease, unless a
shorter useful life is expected.

The other tangible assets category mainly consists of assets under construction. Assets under
construction are not depreciated.

Any gain or loss incurred at the disposal of an asset is determined as the difference between the
sale proceeds and the carrying amount of the asset and is recognized in profit or loss.

Leases

All leases are accounted for by recognizing a right-of-use asset and a corresponding lease liability
except for:

Leases of low value assets; and

Leases with a duration of 12 months or less.

Liabilities arising from a lease are initially measured on a present value basis. Lease liabilities
include the net present value of the lease payments that are not paid at the commencement
date, discounted using the rate implicit in the lease. If this rate cannot be readily determined,
we will apply the incremental borrowing rate. The lease payments can include fixed payments,
variable payments that depend on an index or rate known at the commencement date, expected
residual value guarantees, termination penalties and extension option payments or purchase
options if we are reasonably certain to exercise this option.

180

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

After initial recognition, the lease liability is measured at amortized cost using the discount
rate determined at commencement and will be re-measured (with a corresponding adjustment
to the related right-of-use asset) when there is a change in future lease payments in case of
renegotiation, changes of an index or rate or in case of reassessment of options.

At the commencement date, the right-of-use assets are measured at cost, comprising the
amount of the initial lease liability, initial direct costs and the expected dismantling and removing
costs (when we incur an obligation for these costs), less any lease incentives received from the
lessors.

After initial recognition, the right-of-use assets are measured at cost and depreciated over the
shorter of the underlying asset’s useful life and the lease term on a straight-line basis. The right-
of-use assets will be adjusted for any re-measurements of the lease liability as a result of lease
modifications. The right-of-use assets are subject to impairment testing if there is an indicator for
impairment, as for property, plant and equipment. The right-of-use assets are presented in the
statement of financial position under the caption “Property, plant and equipment” and the lease
liabilities are presented as current and non-current lease liabilities.

In determining the lease term, we consider all facts and circumstances that create an economic
incentive to exercise an extension option, or not exercise a termination option. We only include
in the lease term if the lease is
extension options (or periods after termination options)
reasonably certain to be extended (or not terminated). The assessment is reviewed if a significant
event or a significant change in circumstances occurs which affects this assessment and that is
within our control.

Each lease payment is allocated between the liability and financial expenses. The finance cost is
charged to the income statement over the lease period so as to produce a constant periodic rate
of interest on the remaining balance of the liability for each period.

Inventories

Inventories consist of raw materials, semi-finished products and finished products purchased for
resale. These inventories are initially recognized at cost, and subsequently at the lower of cost
and net realizable value. Cost comprises all costs of purchase, including transportation costs, and
is determined using the FIFO-method.

Financial instruments

Financial assets and financial liabilities are recognized on our balance sheet when we become a
party to the contractual provisions of the instrument. We do not actively use currency derivatives
to hedge planned future cash flows, nor do we make use of forward foreign exchange contracts.
Additionally, we do not have financial debts at 31 December 2021.

(i) Financial assets

Financial assets are initially recognized either at fair value or at their transaction price. All
recognized financial assets are subsequently measured at either amortized cost or fair value
under IFRS 9 on the basis of both our business model for managing the financial assets and the
contractual cash flow characteristics of the financial asset.

181

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

a financial asset that (i) is held within a business model whose objective is to collect the
contractual cash flows and (ii) has contractual cash flows that are solely payments of principal
and interest on the principal amount outstanding is measured at amortized cost (net of any
write down for impairment), unless the asset is designated at fair value through profit or loss
(FVTPL) under the fair value option;

a financial asset that (i) is held within a business model whose objective is achieved both by
collecting contractual cash flows and selling financial assets and (ii) has contractual terms that
give rise on specified dates to cash flows that are solely payments of principal and interest
on the principal amount outstanding, is measured at fair value through other comprehensive
income (FVTOCI), unless the asset is designated at FVTPL under the fair value option;

all other financial assets are measured at FVTPL.

A financial asset is classified as current when the cash flows expected to flow from the instrument
mature within one year.

We derecognize a financial asset when the contractual rights to the cash flows from the asset
expire, or we transfer the rights to receive the contractual cash flows on the financial asset in a
transaction in which substantially all the risks and rewards of ownership of the financial asset are
transferred.

We classify non-derivative financial assets into the following categories:

financial assets at fair value through profit or loss (equity instruments, current financial
investments and cash equivalents)

financial assets at amortized cost (receivables, current financial investments and cash and
cash equivalents).

(a) Financial assets at fair value through profit or loss

Financial assets are designated at fair value through profit or loss if we manage such investments
and make purchase and sale decisions based on their fair value in accordance with the
investment strategy. Attributable transaction costs are recognized in profit or loss as incurred.
Financial assets at fair value through profit or loss are measured at fair value, and changes
therein, which take into account any dividend income, are recognized in profit or loss.

Equity instruments

We hold investments in equity instruments, which based on IFRS 9, are designated as financial
assets at fair value through profit or loss. The fair value of listed investments is based upon the
closing price of such securities on Euronext at each reporting date. If there is no active market
for an equity instrument, we establish the fair value by using valuation techniques.

Current financial investments measured at fair value through profit or loss

Current financial investments include financial assets measured at fair value through profit or
loss and may comprise short term bond funds that have a maturity equal or less than 12 months,
and money market funds.

182

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

Cash equivalents measured at fair value through profit or loss

Cash equivalents measured at fair value through profit or loss may comprise bonds and money
market funds that are readily convertible to cash and are subject to an insignificant risk of
changes in value.

(b) Financial assets at amortized cost

Receivables

Receivables are designated as financial assets measured at amortized cost. They are initially
measured either at fair value or at transaction price, in the absence of a significant financing
component.

All receivables are subsequently measured in the balance sheet at amortized cost, which
generally corresponds to nominal value less expected credit loss provision.

Receivables mainly comprise trade and other receivables and current/non-current R&D
incentives receivables.

The R&D incentives receivables relate to refunds resulting from R&D incentives on research and
development expenses in France and Belgium. Research and development incentives receivables
are discounted over the period until maturity date according to the appropriate discount rates.

Current financial investments measured at amortized cost

Current financial
investments measured at amortized cost include treasury bills that have a
maturity equal or less than 12 months. We apply settlement date accounting for the recognition
and de-recognition of current financial
investments measured at amortized cost. Current
financial
investments measured at amortized cost also include short-term deposits with
maturities exceeding three months from the acquisition date.

Cash and cash equivalents measured at amortized cost

Cash and cash equivalents measured at amortized cost mainly comprise of notice accounts and
short-term deposits that are readily convertible to cash within three months or less and and that
are subject to an insignificant risk of changes in their value .

Cash and cash equivalents exclude restricted cash, which is presented in the line other non-
current assets in the statement of financial position.

(ii) Financial liabilities

Financial
Subsequent to initial recognition, financial liabilities are measured at amortized cost.

liabilities are initially measured either at fair value or at their transaction price.

Financial liabilities mainly comprise trade and other liabilities.

Trade and other liabilities are comprised of liabilities that are due less than one year from the
balance sheet date and are in general not interest bearing and settled on an ongoing basis during
the financial year. They also include accrued expense related to our research and development
project costs.

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

We derecognize a financial liability when our contractual obligations are discharged, cancelled or
expire.

(iii) Financial instruments: derivative assets/liabilities

Financial assets and financial liabilities are recognized on our balance sheet when we become a
party to the contractual provisions of the instrument.

Derivative assets and liabilities are initially measured at fair value. After initial measurement we
will measure the derivatives at fair value through profit or loss.

Taxation

Income tax in the profit or loss accounts represents the sum of the current tax and deferred tax.

Current tax is the expected tax payable on the taxable profit of the year. The taxable profit of the
year differs from the profit as reported in the financial statements as it excludes items of income
or expense that are taxable or deductible in other years and it further excludes items that are
never taxable or deductible. Our liability for current tax is calculated using tax rates that have
been enacted or substantively enacted by the balance sheet date.

Deferred income tax is provided in full, using the liability-method, on temporary differences
arising between the tax bases of assets and liabilities and their carrying amounts in the financial
statements. However, the deferred income tax is not accounted for if it arises from the initial
recognition of an asset or liability in a transaction other than a business combination that at the
time of the transaction affects neither accounting nor taxable profit nor loss.

Deferred income tax is determined using tax rates (and laws) that have been enacted or
substantively enacted by the balance sheet date and are expected to apply when the related
deferred income tax asset is realized or the deferred income tax liability is settled. Deferred tax
assets are recognized to the extent that it is probable that future taxable profit will be available
against which the temporary differences can be utilized. As such, a deferred tax asset for the
carry forward of unused tax losses will be recognized to the extent that is probable that future
taxable profits will be available.

Foreign currencies

Functional and presentation currency

Items included in the financial statements of each of our entities are valued using the
currency of

consolidated financial statements are presented in Euros, which is our presentation
currency.

Transactions and balances in foreign currency

Foreign currency transactions are translated into the functional currency using the exchange
rates prevailing at the dates of transaction. Foreign currency gains and losses resulting from
the settlement of such transactions and from the translation at closing rates of monetary
assets and liabilities denominated in foreign currencies are recognized in the financial result
in the income statement.
Non-monetary assets and liabilities measured at historical cost that are denominated in
foreign currencies are translated using the exchange rate at the date of the transaction.

Financial statements of foreign group companies

The results and financial position of all our entities that have a functional currency different
from Euro are translated as follows:

Assets and liabilities for each balance sheet presented are translated at the closing rate
at the date of that balance sheet

Income and expenses for each income statement are translated at average exchange
rates

All resulting cumulative exchange differences are recognized as a separate component
of equity

Such cumulative exchange differences are recognized in profit or loss in the period in
which the foreign operation is disposed of.

Recognition of expenses linked to clinical trial milestones

We recognize expenses specifically linked to clinical trial milestones with regard to patient
recruitment and patient treatment (i.e. completion), incurred in carrying out clinical trials, in line
with actual patient recruitment or treatment at each period end, in reference to the milestone
targets for patient recruitment or treatment.

This involves the calculation of clinical trial accruals at each period end, for which an estimation
of the expected full clinical trial milestone cost is required, as well as the current stage of patient
recruitment or treatment.

Clinical trials usually take place over extended time periods and typically involve a set-up phase,
a recruitment phase and a completion phase which ends upon the receipt of a final report
containing full statistical analysis of trial results. Accruals for patient recruitment and patient
completion are prepared separately for each clinical trial in progress and take into consideration
the stage of completion of each trial including the number of patients that have entered the trial
and the number of patients that have been treated in the trial. In all cases, the full cost of each
trial is expensed by the time the final report is received.

Revenue recognition

Revenues to date have consisted principally of collaboration revenues, which consist of
milestones, license fees, non-refundable upfront fees and royalties received in connection with
collaboration and license agreements. Starting in 2021 we also have commercial revenues from

185

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

the sales of Jyseleca, which are reported as “Product net sales” in our consolidated income
statement. We also generated revenue from our fee-for-service activities, which is reported as
discontinued operations per 31 December 2020.

The revenue recognition policies can be summarized as follows:

We recognize revenue when our customer obtains control of promised goods or services, in an
amount that reflects the consideration that we expect to receive in exchange for those goods
or services. To determine revenue recognition for agreements that we determine are within the
scope of IFRS 15, we perform the following five steps:

Collaboration revenues

(i) identify the contract

In our current agreements with customers we are mainly transferring licenses on our IP and
in some cases this is combined with access rights and/or providing research and development
services and/or cost sharing mechanisms. In some cases our collaborations also include an
equity subscription component. If this is the case, we analyze if the criteria to combine contracts,
as set out by IFRS 15, are met.

(ii) identify the performance obligations in the contract

Depending on the type of the agreement, there can be one or more distinct performance
obligations under IFRS 15. This is based on an assessment of whether the promises in an
agreement are capable of being distinct and are distinct from the other promises to transfer
goods and/or services in the context of the contract. For some of our agreements we combine
the transfer of the license with the performance of research and development activities because
we consider that the license is not capable of being distinct and is not distinct in the context of
the contract.

(iii) determine the transaction price

Collaboration and license agreements with our commercial partners for research and
development activities generally include non-refundable upfront fees; milestone payments, the
receipt of which is dependent upon the achievement of certain clinical, regulatory or commercial
milestones; license fees, royalties on sales and sometimes reimbursement income or profits
sharing arrangements.

(a) License fees or upfront payments

If the license to our intellectual property is determined to be distinct from the other performance
obligations identified in the arrangement, we recognize revenues from non-refundable upfront
fees allocated to the license at the point in time the license is transferred to the customer and
the customer has the right to use the license.

For licenses that are bundled with other promises, we utilize judgment to assess the nature of the
combined performance obligation to determine whether the combined performance obligation
is satisfied over time or at a point in time. If the performance obligation is satisfied over time,
revenue is recognized based on a pattern that best reflects the transfer of control of the service
to the customer.

186

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

(b) Milestone payments other than sales based milestones

A milestone payment is only included in the transaction price to the extent that it is highly probable
that a significant reversal in the amount of cumulative revenue recognized will not occur when the
uncertainty associated with the variable consideration is subsequently resolved. Where milestone
payments are included in the transaction price we estimate the amount to be included in the
transaction price using the most likely amount method. The transaction price is allocated to each
performance obligation on a stand-alone selling price basis. We recognize revenue as or when the
performance obligations under the contract are satisfied. At the end of each subsequent reporting
period, we re-evaluate the probability of achievement of relevant milestones and any related
constraint. If necessary we adjust our estimate of the overall transaction price. Any such adjustments
are recorded on a cumulative catch-up basis, which would affect revenue and earnings in the period
of adjustment.

(c) Reimbursement income for R&D services

Collaboration and license agreements may include reimbursement or cost sharing for research
and development services: such as outsourcing costs and payment for full-time equivalents at
contractual rates. R&D services are performed and satisfied over time given that the customer
simultaneously receives and consumes the benefits provided by us.

Such costs reimbursements received are recognized in revenues when costs are incurred and agreed
by the parties when we are acting as a principal in the scope of our stake of the R&D activities. If the
later condition is not fulfilled, costs reimbursements are accounted for as a decrease of the related
expenses.

(d) Sales based milestone payments and royalties

License and collaboration agreements include sales-based royalties, including commercial milestone
payments based on the level of sales, and the license has been deemed to be the predominant item
to which the royalties relate. Related revenue is recognized as the subsequent underlying sales occur.

(iv) allocate the transaction price to the performance obligations in the contract

We allocate the transaction price to each performance obligation identified in the contract based
upon stand-alone selling price. The stand-alone selling price of each performance obligation is
estimated by using one of the following methods: adjusted market assessment approach, the
expected cost plus a margin approach or the residual approach. If management assesses that there
is only one single performance obligation, the entire transaction price would be allocated to this
performance obligation.

(v) recognize revenue when (or as) the entity satisfies a performance obligation

Revenue is recognized when our customer obtains control of the goods and/or services foreseen
in the contracts. The control can be transferred over time or at a point in time – which results in
recognition of revenue over time or at a point in time.

In case of revenue recognition over time, we use either an input model that considers estimates
of the percentage of total research and development costs that are completed each period
compared to the total estimated costs (percentage of completion method) or we apply an output
method to measure the progress of the satisfaction of the underlying performance obligation. In
other cases, depending on specific circumstances, we recognize revenue on a straight-line basis
over the estimated term of the performance obligation.

187

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

Product net sales

Revenue on the sale of Jyseleca is recorded as “Product net sales” in our consolidated income
statement.

Product net sales is the net amount of revenue recognized resulting from transferring control
over our products to our customer (for example wholesalers and hospitals). Product sales
revenue is recognized at a point in time when control of the goods has transferred to the
customer. This is generally when the goods are delivered to the customer depending on the
specific incoterms in the contract with a customer.

The amount of revenue recognized is the amount allocated to the satisfied performance
obligation taking into account variable consideration. The estimated amount of variable
consideration is included in the transaction price only to the extent that it is highly probable
that a significant reversal in the amount of cumulative revenue recognized will not occur when
the uncertainty associated with the variable consideration is subsequently resolved. Variable
consideration that is included in the transaction price is primarily composed of rebates,
discounts, cash discounts and chargebacks granted to various customers that are part of
commercial and governmental contractual arrangements or other reimbursement programs.
Shelf stock adjustments are granted to some of our customers to cover the inventory held by
them at the time of a price decrease becomes effective. A liability is recognized for expected
rebates, cash discounts, chargebacks or other reimbursements payable directly or indirectly to
customers in relation to sales made until the end of the reporting period.

The amount of variable consideration is estimated using several elements such as third-party
market data, product pricing, the specific terms in the individual agreements, estimated inventory
levels and the shelf life of our product. If actual results differ, these estimates will be adjusted.

Net sales are presented net of value added tax and other sales related taxes.

We refer to note 6 for detailed information per agreement and to our Critical accounting
judgments and key sources of estimation uncertainty for more information.

Cost of sales

Our cost of sales includes primarily the purchase cost of the goods sold and transportation costs.

Other operating income

Grants and R&D incentives

As we carry out extensive research and development activities, we benefit from various grants
and R&D incentives from certain governmental agencies. These grants and R&D incentives
generally aim to partly reimburse (approved) expenditures incurred in our research and
development efforts and are credited to the income statement, under other income, when the
relevant expenditure has been incurred and there is reasonable assurance that the grants or
R&D incentives are receivable.

FINANCIAL STATEMENTS

Equity instruments

Equity instruments issued by us are measured by the fair value of the proceeds received, net of
direct issue costs.

Employee benefits

(i) Defined contribution plans

Contributions to defined contribution pension plans are recognized as an expense in the income
statement as incurred.

(ii) Defined benefit plans

For defined retirement benefit plans, the cost of providing benefits is determined using the
projected unit credit method, with actuarial valuations being carried out at the end of each
annual reporting period. Re-measurement, comprising actuarial gains and losses, the effect of
the changes to the asset ceiling (if applicable) and the return on plan assets (excluding interest),
is reflected immediately in the statement of financial position with a charge or credit recognized
in other comprehensive income in the period in which they occur. Re-measurement recognized
in other comprehensive income is reflected immediately in retained earnings and will not be
reclassified to profit or loss. Past service cost is recognized in profit or loss in the period of a
plan amendment. Net interest is calculated by applying the discount rate at the beginning of the
period to the net defined benefit liability or asset.

Defined benefit costs are categorized as follows:

Service cost (including current service cost, past service cost, as well as gains and losses on
curtailments and settlements)

Net interest expenses or income

Re-measurement

The retirement benefit obligation recognized in the consolidated statement of financial position
represents the actual deficit or surplus in our defined benefit plans. Any surplus resulting from
this calculation is limited to the present value of any economic benefits available in the form
of refunds from the plans or a reduction in future contributions to the plans. A liability for a
termination benefit is recognized at the earlier of when we can no longer withdraw the offer of
the termination benefit and when we recognize any related restructuring costs.

(iii) Staff bonus plan

We recognize an expense in the income statement for staff bonus plans.

(iv) Management bonus plan

(a) Bonuses which were granted for performance years until 2018

The management board members, together with other senior managers, are eligible to receive
bonuses under the Senior Management Bonus Scheme established in 2006. Pursuant to the
rules of the Senior Management Bonus Scheme, 50% of the bonus is paid immediately around

189

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

year-end and the payment of the remaining 50% is deferred for three years. The deferred 50%
component is dependent on the Galapagos share price change relative to the Next Biotech
Index (which tracks Euronext-listed biotech companies). The Galapagos share price and the Next
Biotech Index at the start and end of the 3‑year period is calculated by the average price over the
preceding and last month of the 3‑year period, respectively.

If the Galapagos share price change is better than or equal to the change in the Next Biotech
Index, the deferred bonus will be adjusted by the share price increase/decrease percentage
and paid out

If the Galapagos share price change is up to 10% worse than the change in the Next Biotech
Index, 50% of the deferred bonus will be adjusted by the share price increase/decrease
percentage and paid out, and the remainder will be forfeited

If the Galapagos share price change is more than 10% worse than the change in the Next
Biotech Index the deferred bonus will be forfeited

We recognize the possible payment of the deferred component of the Senior Management
Bonus Scheme within three years at the moment that the bonus amount is determined, based
on the fair value of the liability at each reporting period. The fair value of the liability is measured
by use of the Monte Carlo valuation model taking into consideration (a) the average reference
price of the Galapagos share and Next Biotech Index, (b) the average price of the reporting period
of the Galapagos share and the Next Biotech Index, (c) the simulation of the evolution of the
Galapagos share price and the Next Biotech Index based on their volatility and correlation until
maturity of the bonus, (d) the applicable discount rates at the end of the reporting period and
(e) the probability of the number of beneficiaries assumed to stay with us until maturity of the
bonus. The changes in fair value are recognized in profit or loss for the period.

(b) Bonuses which were granted for performance year 2019 and beyond

The management board members, together with other senior managers are eligible to receive a
bonus based on achievement of personal and corporate objectives. This bonus is paid in cash.

Share-based payments

(i) Equity-settled share-based payments

We grant equity-settled incentives to certain employees, members of the supervisory board and
consultants in the form of subscription rights. Equity-settled subscription rights are measured
at fair value at the date of acceptance. The fair value determined at the acceptance date of
the subscription rights is expensed over time until the end of the vesting period, based on our
estimate of subscription rights that are expected to be exercised. Fair value is measured by use
of the Black & Scholes model. The expected life used in the model has been adjusted, based
on management’s best estimate, for the effects of non-transferability, exercise restrictions, and
behavioral considerations.

190

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

(ii) Long-term incentive plans in RSUs (Restricted Stock Units)

Management board members and other employees are granted RSUs. An RSU is a grant that
takes the form of a promise that employees will receive Galapagos stock in the future and it will
be payable, at the company’s discretion in cash or in shares, upon completion of a certain vesting
period. Each RSU reflects the value of one Galapagos share.

The RSUs are measured based on the volume weighted average share price over the 30-calendar
day period preceding the measurement date. We recognize the corresponding expense and
liability over the vesting period. The fair value of the liability is re-measured at each reporting date
because currently it is management’s intention to settle the RSUs in cash.

Provisions

Provisions are recognized on the balance sheet when we have a present obligation as a result
of a past event; when it is probable that an outflow of resources embodying economic benefits
will be required to settle the obligations and a reliable estimate can be made of the amount of
the obligations. The amount recognized as a provision is the best estimate of the expenditure
required to settle the present obligation at the balance sheet date. If the effect is material,
provisions are determined by discounting the expected future cash flows at a pre-tax rate that
reflects current market assessments of the time value of the money and, when appropriate, the
risk specific to the liability.

Impairment

(i) Financial assets

The impairment loss of a financial asset measured at amortized cost is calculated based on the
expected loss model.

For trade receivables, in the absence of a significant financing component, the loss allowance
is measured at an amount equal to lifetime expected credit losses. Those are the expected
credit losses that result from all possible default events over the expected life of those trade
receivables.

Impairment losses are recognized in the consolidated income statement.

(ii) Property, plant and equipment and intangible assets

For intangible assets with an indefinite life or intangible assets not available for use yet, we
perform an impairment test at least on an annual basis. Furthermore we review at each balance
sheet date the carrying amount of our tangible and intangible assets to determine whether
there is any indication that those assets have suffered an impairment loss. If any such indication
exists, the recoverable amount of the asset is estimated in order to determine the extent of the
impairment loss (if any). Where the asset does not generate cash flows that are independent
from other assets, we estimate the recoverable amount of the cash-generating unit to which the
asset belongs. If the recoverable amount of an asset or cash generating unit is estimated to be
less than the carrying amount, the carrying amount of the asset is reduced to its recoverable
amount. An impairment loss is recognized as an expense immediately.

191

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

When an impairment loss subsequently reverses, the carrying amount of the asset is increased to
the revised estimate of its recoverable amount, but so that the increased carrying amount does
not exceed the carrying amount that would have been determined, had no impairment loss been
recognized for the asset in prior years. A reversal of an impairment loss resulting from a sale
of a subsidiary is recognized as income. In other cases impairment losses of goodwill are never
reversed.

Net income/loss per share

Basic net income/loss per share is computed based on the weighted average number of shares
outstanding during the period. Diluted net income per share is computed based on the weighted
average number of shares outstanding including the dilutive effect of subscription rights, if any.

Segment reporting

We currently have one operating and reportable segment. Prior to the disposal of our fee-for-
service business Fidelta our reportable segments were R&D and fee-for-service business. Fidelta
is reported as discontinued operations at 31 December 2020 and at 31 December 2021.

Assets held for sale and discontinued operations

A discontinued operation is a component of an entity that either has been disposed of, or
that is classified as held for sale. It must either: represent a major separate line of business or
geographical area of operations; be part of a single coordinated disposal plan; or be a subsidiary
acquired exclusively with a view to resale.

Intercompany transactions between continuing and discontinued operations are eliminated
against discontinuing operations.

Non-current assets and disposal groups are classified as assets held for sale if their carrying
amount is to be recovered principally through a sale transaction rather than through continuing
use. This condition is regarded as met only when the sale is highly probable and the asset (or
disposal group) is available for immediate sale in its present condition.

They are stated at the lower of carrying amount and fair value less costs to sell with any resulting
impairment recognized. Assets related to discontinued operations and assets of disposal group
held for sale are not depreciated.

On 4 January 2021 we sold of our fee-for-service business Fidelta. We classified the assets and
the associated liabilities of Fidelta as held for sale in our financial statements for the year ended
31 December 2020.

4. Critical accounting judgments and key sources of
estimation uncertainty

In the application of the accounting policies, we are required to make judgments, estimates and
assumptions about the carrying amounts of assets and liabilities that are not readily apparent
from other sources. The estimates and associated assumptions are based on historical
experience and other factors that are considered to be relevant. Actual results may differ from
these estimates.

Our estimates and assumptions are reviewed on an ongoing basis. Revisions to accounting
estimates are recognized in the period in which the estimate is revised if the revision affects only
that period or in the period of the revisions and future periods if the revision affects both current
and future periods.

The following are the critical
judgments that we have made in the process of applying the
accounting policies and the key sources of estimation uncertainty that have the most significant
effect on the amounts recognized in the consolidated financial statements presented elsewhere
in this annual report.

Critical judgments in applying accounting policies

IFRS 15 – Revenue recognition Gilead

Our critical judgments were as follows:

Identification of the contract

Despite our obligation to pay future sales-based royalties to Gilead and a change in the
governance structure for the development activities, management judged that all activities
are still beneficial for the further development of filgotinib, for which Gilead still owns the ex-
Europe rights. All contract modifications have thus been analyzed following the requirements
of IFRS 15 as we concluded that Gilead is still to be considered as a customer. This is also
supported by the fact that we concluded that there continues to be only one performance
obligation with respect to filgotinib.

Identification of the performance obligation

The modifications of 2020 and 2021 did not give rise to new performance obligations. There
was only a change in scope and price of the existing filgotinib performance obligation, which
was only partly satisfied at the time of the modification. It is management’s judgement that
the Group A and Group B development activities (see note 2 for more details) still to be
performed are interrelated and thus cannot be seen as separate performance obligations.
Based on this, the contract modification has been treated on a cumulative catch-up basis
under IFRS 15.

193

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

Allocation of the total transaction price

The increased fixed consideration as result of the modifications has been allocated in its
entirety to the filgotinib performance obligation. We assessed that the contract modification
only changes the scope of the filgotinib performance obligation and the change in both
fixed and variable consideration is reflective of the updated stand-alone selling price for
the remaining activities of this performance obligation. If we would have concluded that
the increased consideration was not, or only partially, related to the filgotinib performance
obligation, the consideration would have been potentially allocated to other performance
obligations in the contract, which would alter the timing of revenue recognition.

The denominator used in the calculation of the percentage of completion reflects our best
estimate of the total costs to complete the filgotinib performance obligation. These costs
were assessed considering management’s best estimate of the design and duration of
ongoing and planned clinical trials

Key sources of estimation uncertainty

The following are the key sources of estimation uncertainty that have the most significant
effect on the amounts recognized in our consolidated financial statements for the year ended
31 December 2021.

Costs to complete the filgotinib performance obligation

The denominator used in the calculation of the percentage of completion reflects our best
estimate of the total costs to complete the filgotinib performance obligation (which is
composed of the actual costs already incurred at reporting date and our best estimate of
the remaining costs to complete the performance obligation). As our estimate of the costs
is depending on the evolution of the development activities, it may be subject to change
in the future. If the outcome of certain activities would be different from the assumptions
that we made, it could lead to a material adjustment to the total estimated costs, resulting
in a reallocation of revenue between current and future periods. Revenue recognized for
upfront payments and milestone payments in 2021 amounted to €235.7 million. Our total
deferred income balance related to this filgotinib performance obligation amounts to €604.9
million on 31 December 2021. At reporting date, had our best estimate of the remaining
cost to complete the filgotinib performance obligation been increased by 5%, this would have
resulted in a decrease in revenue recognition in 2021 of €16.7 million and a corresponding
increase in current and non-current deferred income. Had our best estimate of the
remaining cost to complete the filgotinib performance obligation been decreased by 5%, this
would have resulted in an increase in revenue recognition in 2021 of €17.5 million and a
corresponding decrease in current and non-current deferred income.

to the filgotinib agreement amounted to €235.7 million in 2021. We recognize the consideration
from Gilead allocated to the drug discovery platform on a linear basis over 10 years, of which
we recognized €230.6 million in 2021. Additionally, for the year ended 31 December 2021, we
recognized in revenue €3.8 million of royalties from Gilead on filgotinib.

(1) With regard to the additional consideration received as a result of the Option, License and Collaboration

agreement (14 July 2019) allocated to the filgotinib performance obligation, we assumed the existence of a
significant financing component estimated to €44.5 million as of 31 December 2019 reflecting the time value of
money on the estimated recognition period. This financing component was reassessed to €55.3 million as of 31
December 2020, and to €57.3 million on 31 December 2021.

A summary of our main contracts with customers is given below:

Collaboration with Gilead

We refer to note 2 of this financial report for a general description of our collaboration with Gilead.

We retain the following three performance obligations, of which the first one was satisfied completely
in 2019; (i) the transfer of an extended license on GLPG1690, (ii) the granting of exclusive access to
our drug discovery platform (i.e. the IP, technology, expertise and capabilities) during the collaboration
period and exclusive option rights on our current and future clinical programs after Phase 2 (or, in
certain circumstances, the first Phase 3 study) outside Europe and (iii) an increased cost share from
20/80 to 50/50 to 100/0 (for Group A activities only) on the global development activities of filgotinib,
until we complete the remaining development activities (Group A and Group B activities).

198

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

We concluded as follows:

Determination of the total transaction price

We assessed that the contract modifications of 15 December 2020 and 6 September 2021
only change the scope of the filgotinib performance obligation and the changes in both
fixed and variable consideration are reflective of the updated stand-alone selling price for
the remaining activities of this performance obligation. As a result of these modifications,
there were increases in the transaction price of €160.0 million and $15.0 million, respectively,
which have been allocated in their entirety to the filgotinib performance obligation.

Financing component

Management has considered it is appropriate to adjust the part of the transaction price
that was allocated to the filgotinib performance obligation, for the time value of money. The
additional consideration as a result of the contract modification of 15 December 2020 has
also been adjusted for the time value of money.

License on GLPG1690

This performance obligation is completely satisfied at 31 December 2019. Following the
discontinuation of the ziritaxestat trials, we do not expect future milestone payments or
royalties.

After granting the license for GLPG1690, we shared Phase 3 costs equally with Gilead.
Any cost reimbursement from Gilead was not recognized as revenue but accounted as a
decrease of the related expenses.

Filgotinib amendment

There is one single performance obligation under IFRS 15: the transfer of a license combined
with performance of R&D activities. This is because we considered that the license is not
distinct in the context of the contract.

The transaction price is currently composed of a fixed part, being non-refundable upfront
and license fees and a variable part, being milestone payments, sales based milestones
and sales based royalties, and cost reimbursements for R&D activities delivered. Milestone
payments are included in the transaction price of the arrangement to the extent that it is
highly probable that a significant reversal of revenue will not occur. Milestone payments
received from Gilead are recognized in revenue over time till the end of the development
plan. Sales based milestones and sales based royalties are also part of the arrangement and
are recognized as revenues at a point in time at the moment they occur. During 2020 and
2021 we reported respectively €16.2 million and €3.8 million of revenues from royalties from
Gilead.

Revenues, excluding sales based milestones and sales based royalties, are recognized over
time through satisfaction of the performance obligation. The “cost-to-cost” input model is
applied to measure the progress of the satisfaction of this performance obligation. The
estimated costs to complete the performance obligation have been reassessed as a result of
the contract modifications from 2020 and 2021.

199

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

Access rights to the drug discovery platform, option rights and R&D
activities

The revenue allocated to the drug discovery platform is recognized over time as Gilead
receives exclusive access to our drug discovery platform and option rights on our current
and future pipeline as well as R&D activities during the collaboration term. Management
concluded that an equal spread over the collaboration period is the most reliable and
appropriate recognition method.

At inception of the collaboration (July 2019) we assessed the appropriate period over which
to recognize the drug discovery platform revenue to be 10 years. This is because we granted
exclusive rights over a 10-year period. However, if at the end of the 10-year period, some
programs in existence as of this time would have reached the clinic (i.e. IND filed with
regulatory authorities), the rights for those specific programs may be extended, for a
maximum of three years. This critical estimate is reassessed at each year-end based on the
evolution of our pipeline and is still valid per 31 December 2021.

The decrease in our R&D expenditure was principally due to reduced subcontracting costs
primarily due to the winding down of the programs with ziritaxestat (IPF), MOR106 (atopic
dermatitis) and GLPG1972 (OA) and to reduced spend on our other programs. This was partly
offset by costs increases for our filgotinib, Toledo (SIKi) and TYK2 programs, on a yearly
comparison basis.

200

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

This decrease was partly offset by:

A slight increase in personnel costs explained by an increase in salaries driven by higher
average number of FTEs on a yearly comparison basis, mainly driven by an increase in our
Medical Affairs staff. This increase was partly offset by decreased costs of the subscription
right plans and by a reassessment of the defined benefit accounting of our employee benefit
plans under IFRS.

Impairment of capitalized in-licensing fees, and increase in professional
fees due to
additional consulting expenses related to the implementation of new R&D software
applications.

Increase in other operating expenses, mainly software and license expenses.

(61,757)

The increase in our sales and marketing expenses for the year ended 31 December 2021, is due
to the commercial launch of filgotinib in Europe.

Personnel costs increased explained by an increase in the commercial work force from 99
average FTEs in 2020 to 248 average FTEs in 2021. External outsourcing costs increased primarily
explained by increased costs for marketing campaigns and information, market research and
promotional expenses. This was partially offset by additional cost recharged by us to Gilead in
the scope of our co-commercialization cost sharing for filgotinib in Belgium, the Netherlands,
Luxembourg, France, Italy, Spain, Germany and Great Britain, for which we have recharged
€59.7 million to Gilead in 2021 (compared to €4.7 million recharges for the year ended
31 December 2020). This was due to the shift of commercial activities from Gilead to us in the
course of 2021.

As from 1 January 2022, the 50/50 filgotinib co-commercialization cost sharing agreement with
Gilead will come to its end and we will therefore bear all commercialization costs for Europe.

(118,757)

The increase in our general and administrative expenses in 2021 was mainly due to an
exceptional impairment cost of €9.3 million on other tangible fixed assets following our decision
to reassess the construction project of our new future headquarter location in Mechelen
(Belgium), as well as higher costs for our insurance programs (an increase of €4.0 million
compared to 2020) and the newly applicable tax on securities accounts in 2021 in Belgium for an
amount of €4.3 million, both reported as other operating expenses. The Belgian tax on securities
accounts is an annual tax of 0.15% which is levied on securities accounts of which the average
value calculated according to certain principles would exceed €1.0 million.

The grant income in 2021 was fully related to grants from a Flemish agency and the Belgian
government. In many cases these grant agreements carry clauses which require us to maintain a
presence in the same region for a number of years and invest according to pre-agreed budgets.
Grant income in 2021 included a grant of €5.4 million from the National Institute for Health and
Disability Insurance (2020: €5.0 million). This grant aims to incentivize innovative Belgian biotech
companies who are performing research and development activities in order to identify new
medicines.

Gilead warrants B

We measured the warrants (initial and subsequent warrant B) at fair value and recognized a
warrant issuance liability at closing date of the transaction on 23 August 2019. Upon approval
of the issuance of initial warrant B on 22 October 2019 (warrant approval date) the variable
consideration was re-measured with a corresponding impact on the transaction price allocated
to the performance obligation relating to our drug discovery platform, and the warrant issuance
liability became a financial liability measured at fair value with changes through profit or loss as
from that moment.

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 December 2021. The fair
value measurement of this financial liability is categorized as level 3 in the fair value hierarchy.
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 €3.0 million for the year
ended 31 December 2021, is mainly the result of the decrease of our share price and of its
implied volatility in 2021. The fair value of the financial liability related to the initial warrant B of

The currency exchange gain in 2021 of €60.7 million primarily consisted of an unrealized
exchange gain of €56.6 million on cash and cash equivalents held in U.S. dollars, as compared to
an unrealized exchange loss in 2020 of €106.4 million on cash and cash equivalents and current
financial investments held in U.S. dollars. As from 2021, the currency exchange results on the
current financial investments (an exchange gain of €16.3 million in 2021) are reported, together
with the other fair value results on current financial
investments, on the line fair value gain
(or loss) on current financial investments. We have cash, cash equivalents and current financial
investments held in U.S. dollars, which could generate foreign currency exchange gain or loss in
our financial results in accordance with the fluctuation of the EUR/U.S. dollar exchange rate as
our functional currency is EUR.

Net currency exchange gain amounted to €56.5 million for the year ended 31 December 2021,
compared to a net currency exchange loss of €105.7 million for the year ended 31 December
2020.

Interest expenses were related to interests on term deposits, treasury bills that came to maturity
and on leases of buildings and cars. Other financial expense for 2021 also included €9.3 million
of costs (€16.3 million for the year ended 31 December 2020) linked to the accounting under
IFRS 15 for a financing component embedded in the upfront consideration received from Gilead
in connection with the revised agreement for filgotinib.

Interest income was related to interests on term deposits, notice accounts and current financial
investments.

207

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

For the year ended 31 December 2021, fair value loss on financial assets held at fair value
through profit or loss consisted of negative effects from the fair value re-measurement of
financial assets classified as equity investments which qualify for level 1 fair value measurement
based upon the closing price of such securities at each reporting date, and of an impairment
loss on a participation in a non-listed company. The fair value gain on the current financial
investments in 2021 reflected the positive exchange differences booked on these current
financial
investments, compensated by the interest on the treasury bills which have not yet
expired and the effect of the re-measurement at fair value of our money market funds on
31 December 2021. These re-measurement losses were mainly the result of the negative returns
on the EUR denominated money market funds.

The other tangible assets primarily consist of assets under construction, mainly related to our
new building in Leiden (the Netherlands), which are not yet available for use and therefore not
yet depreciated as per 31 December 2021.

In 2021 we recorded an exceptional
impairment of €9.3 million on the other tangible fixed
assets following our decision to reassess the construction project of our new future headquarter
location in Mechelen (Belgium).

Restricted cash on 31 December 2021 was composed of bank guarantees on real estate lease
obligations in Belgium and in the Netherlands for €1.0 million, and €0.4 million, respectively.

Financial assets held at fair value through profit or loss at 31 December 2020 consisted of equity
instruments of both listed and non-listed companies. During 2021 all equity instruments of listed
companies were sold. We have no restrictions on the sale of these equity instruments and
the assets are not pledged under any of our liabilities. These instruments are designated as

financial assets held at fair value through profit or loss. The fair value of the equity instrument
in the non-listed company which was originally determined mainly by reference to the initial
transaction price (classified as level 3 in the fair value hierarchy) has been reduced to nil at
31 December 2021.

Fair value changes on financial assets with fair value through profit or loss are recognized in other

The increase in R&D incentives receivables is explained by additional R&D incentives reported
in 2021 for €33.2 million (€12.4 million related to French incentives and €20.9 million related
to Belgian incentives), by the release of discounting profit of €0.1 million, decreased by the

217

setup of tax provisions in France and Belgium for respectively €0.7 million and €0.05 million and
decreased by the payments received in 2021 related to French and Belgian incentives amounting
to respectively €18.8 million and €5.5 million. The R&D incentives receivables are future expected
refunds or tax deductions resulting from tax incentives on research and development expenses
in France and Belgium. Non-current R&D incentives receivables are reported at their net present
value and are therefore discounted over the period until maturity date.

The table below provides detailed information on the maturity of the non-current R&D incentives
receivables reported in our balance sheet on 31 December 2021.

Non-current and current trade and other receivables decreased primarily due to the outstanding
receivable as at 31 December 2020 of €160.0 million on Gilead related to the renegotiated
agreement of December 2020 for filgotinib, for which we received payments in 2021 of
€110 million (a receivable of €50 million being still outstanding on 31 December 2021 and
expected to be received in the first quarter of 2022). Additionally, we also recorded a receivable
of €12.6 million ($15 million) from Gilead following the agreement for the take-over by us of the
DIVERSITY clinical trial. We refer to note 2 Summary of significant transaction for more details.

We consider that the carrying amount of trade and other receivables approximates their fair
value.

The other current assets mainly included accrued income from subsidy projects and deferred
charges.

On 31 December 2021, we did not have any provision for expected credit losses.

19. Current financial investments

On 31 December 2021, our current financial
investments amounted to €2,469.8 million
compared to €3,026.3 million on 31 December 2020. On 31 December 2021 these current
financial investments included treasury bills for an amount of €877.3 million (€1,454.4 million
on 31 December 2020), money market
funds of €1,317.5 million (€1,571.9 million on
31 December 2020) and non-cancellable term deposits with a maturity exceeding three months
from the acquisition date of €275.0 million (nil on 31 December 2020). Our portfolio of treasury
issued by Germany. Our money market funds portfolio
bills contains only AAA rated paper,

219

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

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. The funds have an important daily liquidity and
can be easily converted to cash.

On 31 December 2021, our current financial investments included $134.6 million held in USD,
which could generate a foreign currency exchange gain or loss in our financial results in
accordance with the fluctuation of the EUR/USD exchange rate as our functional currency is
EUR. This effect is embedded in the fair value result of current financial investments in our
consolidated income statement.

We refer to note 33 for more information on our current financial investments and to note 10 for

Cash and cash equivalents may comprise cash at banks, bank deposits and money market funds
that are readily convertible to cash and are subject to an insignificant risk of changes in value.
Cash and cash equivalents on 31 December 2021 comprised €1,007.5 million of term deposits
which all had an original maturity longer than 3 months but are readily convertible to cash
without a significant penalty. All cash and cash equivalents are available upon maximum three
month notice period and without significant penalty. Cash at banks were mainly composed of
notice accounts and current accounts. Our credit risk is mitigated by selecting a panel of highly
rated financial institutions for our deposits.

On 31 December 2021, our cash and cash equivalents included $807.9 million held in USD, which
could generate a foreign currency exchange gain or loss in our financial results in accordance
with the fluctuation of the EUR/USD exchange rate as our functional currency is EUR. We refer
to note 10 for more details about the currency exchange gains or losses recognized in our
consolidated income statement.

The net increase in cash and cash equivalents of €90.3 million was composed of (i) €564.8 million
of operational cash burn, (ii) €3.3 million of cash proceeds from capital and share premium
increase from exercise of subscription rights in 2021, (iii) the net sale of current financial

220

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

investments of €566.4 million, (iv) €56.8 million of positive unrealized exchange differences, and
(v) €28.7 million cash proceeds from disposal of Fidelta.

Operational cash burn (or operational cash flow if this liquidity 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:

in the net cash flows generated from/used in (–) investing activities.

development stage.

The supervisory board is authorized for a period of five years starting from the date of publication
in the Annexes to the Belgian State Gazette of the shareholders’ resolution that granted the
renewed authorization to increase the share capital of Galapagos NV within the framework of the
authorized capital through contributions in kind or in cash, with limitation or cancellation of the
shareholders’ preferential subscription rights. Said authorization can be renewed. The authorized
capital of Galapagos NV consists of two parts. A general authorization for capital increases up to
20% of the share capital at the time of convening the shareholders’ meeting of 22 October 2019
(i.e. €67,022,402.04) was renewed and is valid for a period of five years from the date of
publication of this renewal in the Annexes to the Belgian State Gazette, i.e. 13 November 2019. A
specific authorization for capital increases of more than 20% and up to 33% of the share capital
at the time of the convening the shareholders’ meeting of 25 April 2017 (i.e. €82,561,764.93), was
renewed and is valid for a period of five years from the date of publication of this renewal in
the Annexes to the Belgian State Gazette, i.e. 31 May 2017. This specific part of the authorized
capital can, however, only be used in a number of specific circumstances and upon a resolution
of the supervisory board that all independent supervisory board members (within the meaning
of article 7:87 of the Belgian Companies Code and 2020 Code) approve. The supervisory board

225

is currently not authorized to increase the share capital after notification by the FSMA (Financial
Services and Markets Authority) of a public takeover bid on Galapagos NV’s shares. The specific
authorization will expire on 30 May 2022.

As of 31 December 2021, an amount of €41,775,187.16 still remained available under the general
part of the authorized capital and an amount of €13,717,929.80 remained available under the
specific part of the authorized capital.

the dividend received deduction and investment deduction carried forward.

With the exception of 2019, we have a history of losses. We forecast to continue incurring taxable
losses in the foreseeable future as we continue to invest in clinical and preclinical development
programs and discovery platforms. Consequently, no deferred tax asset was recognized as at
31 December 2021, except for subsidiaries operating on a cost plus basis, for which deferred tax
assets were recognized for €4.0 million (2020: €4.5 million).

29. Contingent assets and liabilities

On 4 January 2021, we closed the sale of our Croatian subsidiary Fidelta. Selvita acquired 100%
of the outstanding shares in Fidelta for a total consideration of €37.1 million. In accordance with
common practice, we gave representations and warranties which are capped and limited in time.

As explained in the summary of the significant transaction in note 2 to our consolidated financial
statements, Gilead and we entered into a license and collaboration agreement to co-develop
filgotinib in different indications. The collaboration was amended several times and in connection
with these amendments Gilead has agreed to irrevocably pay us €160 million, subject to certain
adjustments for higher than budgeted development costs. Gilead paid €110 million in 2021 and
will pay an additional €50 million in 2022. In addition, we will no longer be eligible to receive
any future milestone payments relating to filgotinib in Europe. However, we will remain eligible
to receive tiered royalty percentages ranging from 20% to 30% on Gilead’s global net sales of
filgotinib outside of Europe and future development and regulatory milestone-based payments
of up to $295 million and sales-based milestone payments of up to $600 million. We will pay
royalties on net sales of filgotinib in Europe to Gilead starting 1 January 2024. Under the terms of
the 2021 amendment and upon completion of the transfer of the DIVERSITY clinical study, Gilead
will make a one-time payment of $15 million to us in consideration for assuming responsibility
for this clinical study. From 1 April 2022, we will also be solely responsible for all development
if the European Medicines Agency grants
costs for the DIVERSITY clinical study. In addition,
regulatory approval of filgotinib for the treatment of CD based on data from the DIVERSITY trial,
then royalties payable by us to Gilead will be reduced by 30% across all filgotinib indications and
will become 5.6% to 10.5% of net sales in Europe. Gilead remains responsible for commercial
activities outside of Europe.

Furthermore Gilead received exclusive option rights to acquire a license on compounds.
Exercising such an option would trigger an opt-in payment, a 50 – 50 cost share mechanism for
the future development activities, potential future development and sales-based milestones and
royalties.

FINANCIAL STATEMENTS

The exercise price of the subscription rights is determined pursuant to the applicable provisions
of the Belgian Law of 26 March 1999.

The weighted average estimated volatility is calculated on the basis of the implied volatility of the
share price over the weighted average expected life of the subscription rights.

The weighted average expected life of the subscription right is calculated as the estimated
duration until exercise, taking into account the specific features of the plans.

Our share based compensation expense in 2021 in relation to subscription right plans amounted
to €70,726 thousand (2020: €79,959 thousand).

The following table provides an overview of the outstanding subscription rights per category of
subscription right holders on 31 December 2021 and 31 December 2020:

subscription rights at 31 December 2020 were reported on the line 'Management board members' while at 31
December 2021 his outstanding subscription rights are presented on the line 'Personnel'.

The outstanding subscription rights at the end of the accounting period have a weighted average
exercise price of €92.69 (2020: €103.95) and a weighted average remaining life of 1,955 days
(2020: 2,050 days).

Restricted stock units (RSUs)

Each RSU represents the right to receive one Galapagos share or a payment in cash of an amount
equivalent to the volume-weighted average price of the Galapagos share on Euronext Brussels
over the 30-calendar day period preceding the relevant vesting date, in accordance with the
terms and conditions of the relevant RSU program.

We currently have the following restricted stock unit (RSU) programs:

Plan 2020.I and Plan 2021.I under which the grants are intended to be made every year, subject
to a decision of the supervisory board. This plan is intended to provide a long-term incentive to
certain of our employees and management board members and replaces the deferred portion
of the bonus under the former Senior Management Bonus Scheme;

Plan 2019.II, Plan 2020.II, Plan 2021.II and Plan 2021.IV. These plans are aimed at retaining a
specific set of our employees and management board members whose retention is deemed so
important for our future performance that an additional incentive is desired. The beneficiaries

240

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

are nominated by the nomination and remuneration committee and the supervisory board
approves the list of beneficiaries;

Plan 2019.I This plan was granted at the discretion of the supervisory board;

Plan 2019.III This exceptional RSU grant took place in 2019 under an RSU Transaction Bonus
Plan for the successful closing of the Gilead transaction;

Plan 2021.III This plan is intended to compensate employees who transferred from Gilead to
us in the framework of the transfer of European commercialization rights, for the long-term
incentive plans within Gilead under which unvested RSU awards lapse upon transfer out of the
Gilead group. These employees received a one-time Restricted Stock Units grant from us.

The main characteristics of all these plans are as follows:

the RSUs are offered for no consideration;

generally four-year vesting period, with 25% vesting each year, except for some plans or
some beneficiaries for which the RSUs will all vest at the same time three years after the offer
date (bullet vesting); vest 50% after two years and 50% after three years or vest over three
years with 34% vesting the first year and 33% in each of the remaining two years;

payout will be in cash or shares, at Galapagos’ discretion, it being understood that in respect
of members of the management board, any vesting prior to the third anniversary of the offer
date will always give rise to a payment in cash rather than a delivery of shares as an incentive;

any unvested RSUs are forfeited upon termination of service before the vesting date.

Relationship and transactions with entities with control of, or
significant influence over, Galapagos

Gilead

Gilead is exercising significant influence over Galapagos as from the equity subscription on
23 August 2019. As a result of the equity subscription we received a transparency notification
from Gilead on 28 August 2019 confirming they held 22.04% of the then issued and outstanding
shares of Galapagos.

By exercising warrant A on 6 November 2019, Gilead increased its ownership in Galapagos
to 25.10% of the then outstanding shares. Gilead further increased its ownership to 25.84%
at 31 December 2019. Gilead’s ownership then diluted to 25.54% at 31 December 2020 and
to 25.49% at 31 December 2021, due to four capital increases resulting from the exercise of
subscription rights under employee subscription right plans in the course of respectively 2020
and 2021.

The presumption of significant influence is also confirmed by the fact that Gilead has the right,
for as long as it holds more than 20% of Galapagos’ share capital, to appoint two investor board
designees to Galapagos’ supervisory board, out of a total of eight.

The following balances are outstanding at the end of the reporting period in relation to Gilead:

The trade and other receivables on 31 December 2021 contain €50 million of receivables related
to the in 2020 modified collaboration for filgotinib, for which we already received €110.0 million
in the course of 2021. They also contain €12.6 million related to the transfer of the sponsorship
and operational and financial responsibility of the ongoing DIVERSITY clinical trial from Gilead to
us, €23.8 million of profit and cost sharing receivables relating to our collaboration for filgotinib
and €1.9 million receivables relating to royalties. The outstanding liabilities mainly relate to the
cross charges from Gilead for the development costs sharing of filgotinib in the fourth quarter of
2021 (€5.7 million) and €1.6 million to purchases of finished goods.

During 2021 we recognized in revenue €230.6 million (€229.6 million for the year ended
31 December 2020) relating to the performance obligation for the drug discovery platform and
a total of €235.7 million (€228.1 million for the year ended 31 December 2020) representing
the total impact on our revenues coming from the filgotinib performance obligation. The latter
consists of upfront payments and milestone payments that were recognized in accordance with
the percentage of completion of the underlying performance obligation.

244

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

Additionally, we recognized in 2021 royalty income for an amount of €3.8 million in relation to the
commercialization of filgotinib (€16.2 million for the year ended 31 December 2020).

Furthermore, we recognized €18.1 million (€34.1 million for the year ended 31 December 2020)
of cost reimbursements from Gilead related to the development of GLPG1690 as a decrease
of the related expenses (on the line research and development expenditure). An amount of
€81.3 million (€101.0 million for the year ended 31 December 2020) relating to cross charges
from Gilead relating to filgotinib was recognized as expense on the line research and
development expenditure.

Finally, we recognized in 2021 €59.7 million as a deduction of sales and marketing expenses and
€7.0 million as a deduction of research and development expenditure (compared to a deduction
of €4.7 million of sales & marketing expenses and a deduction of €3.1 million of research &
development expenditure for the year ended 31 December 2020) mainly relating to our 50/50
profit/(cost) share mechanism with Gilead for direct sales of filgotinib in the shared territory and
expenses incurred for the co-promotion activities for filgotinib.

We purchased raw materials, semi-finished products and finished products of Jyseleca from
Gilead for an amount of €24.9 million for the year ended 31 December 2021 (€0.2 million for the
year ended 31 December 2020).

As at 31 December 2021 we have two outstanding performance obligations under IFRS 15
towards Gilead, being the performance obligation related to our drug discovery platform and
the performance obligation relating to filgotinib. This results in an outstanding deferred income
balance of €1.8 billion for the drug discovery platform (including the warrant issuance liability
relating to subsequent warrant B) and €605 million for the performance obligation relating to
filgotinib.

A detailed explanation of our transactions with Gilead in 2020 and 2021 can be found in
the section titled Agreements with major Galapagos NV shareholders. There are no other
shareholders or other entities who, solely or jointly, control Galapagos or exercise significant
influence over Galapagos.

Financial risk factors

Our financial risks are managed centrally. Our finance department coordinates the access to
national and international financial markets and considers and manages continuously the
financial risks concerning our activities. These relate to the following financial markets risks: credit
risk, liquidity risk, currency and interest rate risk. Our interest rate risk is limited because we have
nearly no financial debt. In case of decreasing interest rates we will face a reinvestment risk on
our strong cash and cash equivalents and current financial investments balance. We do not buy
or trade financial instruments for speculative purposes.

The carrying amounts of trade payables and trade receivables are considered to be the same as
their fair values, due to their short-term nature.

Financial assets held at fair value through profit or loss

Financial assets held at fair value through profit or loss consisted of equity instruments of listed/
non-listed companies and current financial investments.

We have no restrictions on the sale of these equity instruments and the assets are not pledged
under any of our liabilities. These instruments are classified as financial assets held at fair value
through profit or loss. The equity investments in listed companies qualified for level 1 fair value
measurement based upon the closing price of such securities on Euronext at each reporting
date.

The market price of those shares might face fluctuations and might be affected by a variety of
factors, such as the global economic situation, the business development of competitors, sector
mergers and acquisitions; it is difficult to mitigate this risk.

The fair value of the equity instrument in the non-listed company has been determined mainly by
reference to the initial transaction price (classified as level 3 in the fair value hierarchy).

Current financial investments include money market funds in EUR and USD, which all classify for
level 1 fair value measurement.

Liquidity risk

Current financial investments and cash and cash equivalents amounted to €4,703.2 million on
31 December 2021. Management forecasts our liquidity requirements to ensure that we have
sufficient cash to meet operational needs. We have no credit lines. Such forecasting is based on
realistic assumptions with regards to milestone and upfront payments to be received, taking into
account our past track record, including the assumption that not all new projects that are being
planned will be realized.

251

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

All our cash and cash equivalents have only an insignificant liquidity risk as they are all convertible
upon a maximum three month notice period and without incurring a significant penalty in normal
market circumstances.

Credit risk

The term “credit risk” refers to the risk that counterparty will default on its contractual obligations
resulting in financial loss for us.

The trade receivables consist of receivables on our collaboration partner Gilead, creditworthy
pharmaceutical wholesalers and hospitals in Europe. To limit the risk of financial losses, we have
developed a policy of only dealing with creditworthy counterparties.

We grant credit to our clients in the framework of our normal business activities. Usually, we
require no pledge or other collateral to cover the amounts due. Management continuously
evaluates the client portfolio for creditworthiness. All our receivables are considered collectable.

We applied the IFRS 9 simplified approach to measuring expected credit losses which uses a
lifetime expected loss allowance for all receivables. To measure the expected credit losses,
receivables have been grouped based on credit risk characteristics and the days past due. The
provision for expected credit losses was not significant given that there have been no credit
losses over the last three years and the high quality nature of our customers.

Our cash and cash equivalents are invested primarily in current, notice and term accounts. For
banks and financial institutions, only independently rated parties with a minimum rating of ‘A’ are
accepted at the beginning of the term. Our current financial investments are also kept within
different financial institutions and include term deposits, money market funds and treasury bills
with an AAA rating. The money market funds are invested in a well-diversified portfolio of highly
rated assets.

Interest rate risk

The only variable interest-bearing financial
instruments are cash and cash equivalents and
current financial investments. Our interest rate income is impacted by the negative interest rate
environment in EUR, and the low interest rate environment in USD.

Changes in interest rates may cause variations in interest income and expenses resulting from
short-term interest-bearing assets. Management does not expect the short-term interest rates

to decrease significantly in the immediate foreseeable future, which limits the interest exposure
on our cash and cash equivalents and current financial investments.

Effect of interest rate fluctuation

A 100 basis points increase in interest rates at balance sheet date would have increased profit
or loss, and equity, by approximately €47.0 million (2020: €51.7 million); a 100 basis points
decrease in interest rates would have decreased profit or loss, and equity, by approximately
€47.0 million (2020: €51.7 million). These scenarios assume our entire cash portfolio would
immediately reprice at the new interest rates.

Foreign exchange risk

We are exposed to foreign exchange risk arising from various currency exposures. Our principal
functional currency is euro, but we receive payments from our main collaboration partner Gilead
in U.S. dollars and acquire some consumables and materials in U.S. dollars, Swiss francs, and GB
pounds.

To limit this risk, we attempt to align incoming and outgoing cash flows in currencies other than
EUR. In addition, contracts closed by our different entities are mainly in the functional currencies
of that entity, except for the alliance agreement signed with Gilead for which payments are
denominated in U.S. dollars.

The exchange rate risk in case of a 10% change in the exchange rate amounts to:

The exchange rate risk on the U.S. dollar is primarily related to our cash and cash equivalents
and current financial investments held in U.S. dollars.

Capital risk factors

We manage our capital to safeguard that we will be able to continue as a going concern. At
the same time, we want to ensure the return to our shareholders through the results from our
research and development activities.

Our capital structure consists of current financial
investments, cash and cash equivalents,
financial debt (as of 31 December 2021, we only have leasing liabilities), and equity attributed to
the holders of our equity instruments, such as capital, reserves and results carried forward, as
mentioned in the consolidated statement of changes in equity.

253

Galapagos NV Annual Report 2021

FINANCIAL STATEMENTS

We manage our capital structure and make the necessary adjustments in the light of changes
of economic circumstances, the risk characteristics of underlying assets and the projected cash
needs of the current research and development activities.

The adequacy of the capital structure will depend on many factors, including scientific progress in
the research and development programs, the magnitude of those programs, the commitments
to existing and new clinical CROs, the ability to establish new alliance or collaboration
agreements, the capital expenditures, the new commercial activities, market developments and
any future acquisition.

Neither Galapagos NV nor any of its subsidiaries are subject to any externally imposed capital
requirements, other than those imposed by generally applicable company law requirements.

34. Statutory auditor’s remuneration

The statutory auditor’s fees for carrying out its mandate at group level amounted to €860.3
thousand in 2021 (2020: €1,202.8 thousand). Audit-related fees, which generally the auditor
provides, amounted to €101.1 thousand in 2021 (2020: €214.4 thousand). Other fees related
to non-audit services executed by the statutory auditor amounted to €0 in 2021 (2020: €47.7
thousand). Other fees related to non-audit services executed by persons related to the statutory
auditor amounted to €587.7 thousand in 2021 and related to advisory services in relation to
IT and quality management (2020: €890.7 thousand). The audit committee and the supervisory
board are of the opinion that these non-audit services do not affect the independence of the
statutory auditor in the performance of his audit. The abovementioned additional fees were fully
approved by the audit committee in accordance with article 3:64 of the Belgian Companies Code.

35. Events after balance sheet date

On 13 January 2022, the supervisory board approved Subscription Right Plan 2022 (A) within
the framework of the authorized capital. Under this subscription right plan 30,000 subscription
rights were offered and accepted by the beneficiary of the plan. The subscription rights have an
exercise term of eight years as of the date of the offer and have an exercise price of €46.18
(the closing price of the share on Euronext Amsterdam and Brussels on the day preceding the
date of the offer). The subscription rights are not transferable. Subscription rights under this plan
vest in instalments: with 25% of each grant being exercisable as of 1 January 2023, 25% as of
1 January 2024 and 50% (the remainder) as of 1 January 2025.

On 26 January 2022, the supervisory board approved Subscription Right Plan 2022 (B) for the
benefit of a new member of the personnel of Galapagos within the framework of the authorized
capital. Under this subscription right plan 1,000,000 subscription rights were created, subject to
acceptance, and offered to the beneficiary of the plan. The subscription rights have an exercise
term of eight years as of the date of the offer and have an exercise price of €50. The subscription
rights can in principle not be exercised prior to 1 January 2026.

On 18 March 2022, 95,500 subscription rights were exercised (with an average exercise price of
€22.61 per subscription right), of which 50,000 subscription rights were exercised by our CEO
and 10,000 subscription rights by one member of our management board. This resulted in a
share capital increase (including issuance premium) of €2,159,600.00 and the issuance of 95,500
new ordinary shares. The closing price of our share on 18 March 2022 was €57.38.

Our consolidated financial statements were approved by the supervisory board and authorized
for publication on 22 March 2022. They were signed on behalf of the supervisory board by:

REPORT OF THE STATUTORY AUDITOR

Report of the statutory auditor

Statutory auditor’s report to the shareholders’
meeting of Galapagos NV for the year ended 31
December 2021 – Consolidated financial statements

The original text of this report is in Dutch

In the context of the statutory audit of the consolidated financial statements of Galapagos NV
(“the company”) and its subsidiaries (jointly “the group”), we hereby submit our statutory audit
report. This report includes our report on the consolidated financial statements and the other
legal and regulatory requirements. These parts should be considered as integral to the report.

We were appointed in our capacity as statutory auditor by the shareholders’ meeting of 28 April
in accordance with the proposal of the board of directors, now supervisory board
2020,
(“bestuursorgaan” / “organe d’administration”)
issued upon recommendation of the audit
committee. Our mandate will expire on the date of the shareholders’ meeting deliberating on the
financial statements for the year ending 31 December 2022. We have performed the statutory
audit of the consolidated financial statements of Galapagos NV for 16 consecutive periods. We
are the statutory auditor of Galapagos NV for 22 consecutive years.

Report on the consolidated financial statements

Unqualified opinion

We have audited the consolidated financial statements of the group, which comprise the
consolidated statement of financial position as at 31 December 2021,
the consolidated
statement of income and comprehensive income/loss, the consolidated statement of changes in
equity and the consolidated cash flow statement for the year then ended, as well as the summary
of significant accounting policies and other explanatory notes. The consolidated statement of
financial position shows total assets of 5 193 160 (000) EUR and the consolidated statement
of income and comprehensive income/loss shows a loss for the year then ended of 103
231 (000) EUR.

In our opinion, the consolidated financial statements give a true and fair view of the group’s
net equity and financial position as of 31 December 2021 and of its consolidated results and
its consolidated cash flow for the year then ended, in accordance with International Financial
Reporting Standards (IFRS) as adopted by the European Union and with the legal and regulatory
requirements applicable in Belgium.

Basis for the unqualified opinion

We conducted our audit in accordance with International Standards on Auditing (ISA), as
applicable in Belgium. In addition, we have applied the International Standards on Auditing
approved by the IAASB applicable to the current financial year, but not yet approved at national

260

Galapagos NV Annual Report 2021

REPORT OF THE STATUTORY AUDITOR

level. Our responsibilities under those standards are further described in the “Responsibilities of
the statutory auditor for the audit of the consolidated financial statements” section of our report.
We have complied with all ethical requirements relevant to the statutory audit of consolidated
financial statements in Belgium, including those regarding independence.

We have obtained from the supervisory board and the company’s officials the explanations and
information necessary for performing our audit.

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

Key audit matters

Key audit matters are those matters that, in our professional judgment, were of most significance
in our audit of the consolidated financial statements of the current period. These matters were
addressed in the context of our audit of the consolidated financial statements as a whole and in
forming our opinion thereon, and we do not provide a separate opinion on these matters.

Determination of the estimated costs impacting the percentage of completion used for
revenue recognition related to the license and collaboration agreement for filgotinib – Refer
to Notes 2, 4, 6, and 25 to the consolidated financial statements

Key Audit Matter Description

As described in notes 2, 4, 6 and 25 to the consolidated financial statements, the company
recognized collaboration revenues of 235,7 million EUR in 2021 from upfront payments and
milestone payments in relation to the Gilead collaboration agreement for filgotinib (the
“agreement”). For this filgotinib performance obligation, the company recognized revenue using
the cost-to-cost input method, which management believes best depicts the transfer of control to
the customer, being Gilead. Under the cost-to-cost input method, the extent of progress towards
completion is measured based on the ratio of actual costs incurred to the total estimated costs
expected upon satisfying the filgotinib performance obligation.

Significant management judgment is required in determining the total estimated costs required
under the agreement and the period over which the company is expected to complete its
performance obligation. This significant estimate is the principal consideration for our conclusion
the estimated costs to complete the
that procedures relating to the determination of
performance obligation,
impacting the revenue recognition of the filgotinib performance
obligation is a key audit matter. This increased level of judgment by management led to a high
degree of auditor judgment, complexity, and effort in performing procedures and in evaluating
audit evidence related to management’s assumptions related to the estimation of total costs to
complete.

How the Key Audit Matter Was Addressed in the Audit

Our procedures included testing the effectiveness of controls relating to the revenue recognition
process, including controls over the actual costs incurred to date and controls over the inputs
and assumptions used to estimate the total costs required to complete the performance
obligation, as well as increasing the nature and extent of our audit procedures where such
controls were not operating effectively.

261

Galapagos NV Annual Report 2021

REPORT OF THE STATUTORY AUDITOR

These procedures included, among others (i) evaluating and testing management’s process for
determining the estimate of total costs to complete the performance obligation, which included
evaluating the reasonableness of significant assumptions related to the estimate, and (ii) testing,
on a sample basis, the actual costs incurred to date.

Our procedures on the reasonableness of the assumptions used also included evaluating
management’s ability to reasonably estimate costs to complete the performance obligation
by (i) evaluating the appropriateness of changes made during the period to management’s
estimates of total costs to complete; (ii) performing a comparison of management’s prior period
cost estimates to actual costs incurred and approved; (iii) evaluating the period over which
management is expecting the company to complete its performance obligation; (iv) comparing
certain costs to third-party supporting evidence, and (v) performing sensitivities on the current
year’s revenue recognition resulting from changes to these estimates.

Responsibilities of the supervisory board for the preparation
of the consolidated financial statements

The supervisory board is responsible for the preparation and fair presentation of
the
consolidated financial statements in accordance with International Financial Reporting Standards
(IFRS) as adopted by the European Union and with the legal and regulatory requirements
applicable in Belgium and for such internal control as the supervisory board determines is
necessary to enable the preparation of consolidated financial statements that are free from
material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, the supervisory board is responsible for
assessing the group’s ability to continue as a going concern, disclosing, as applicable, matters
to be considered for going concern and using the going concern basis of accounting unless the
supervisory board either intends to liquidate the group or to cease operations, or has no other
realistic alternative but to do so.

Responsibilities of the statutory auditor for the audit of the
consolidated financial statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial
statements as a whole are free from material misstatement, whether due to fraud or error, and to
issue a statutory auditor’s report that includes our opinion. Reasonable assurance is a high level
of assurance, but is not a guarantee that an audit conducted in accordance with ISA will always
detect a material misstatement when it exists. Misstatements can arise from fraud or error and
are considered material if, individually or in the aggregate, they could reasonably be expected
to influence the economic decisions of users taken on the basis of these consolidated financial
statements.

During the performance of our audit, we comply with the legal, regulatory and normative
framework as applicable to the audit of consolidated financial statements in Belgium. The scope
of the audit does not comprise any assurance regarding the future viability of the company nor
regarding the efficiency or effectiveness demonstrated by the supervisory board in the way that
the company’s business has been conducted or will be conducted.

262

Galapagos NV Annual Report 2021

REPORT OF THE STATUTORY AUDITOR

As part of an audit in accordance with ISA, we exercise professional judgment and maintain
professional skepticism throughout the audit. We also:

identify and assess the risks of material misstatement of
the consolidated financial
statements, whether due to fraud or error, design and perform audit procedures responsive
to those risks, and obtain audit evidence that is sufficient and appropriate to provide a
basis for our opinion. The risk of not detecting a material misstatement resulting from
fraud is higher than for one resulting from an error, as fraud may involve collusion, forgery,
intentional omissions, misrepresentations, or the override of internal control;

obtain an understanding of internal control relevant to the audit 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 group’s internal control;

evaluate the appropriateness of accounting policies used and the reasonableness of
accounting estimates and related disclosures made by the supervisory board;

conclude on the appropriateness of the use of the going concern basis of accounting by the
supervisory board and, based on the audit evidence obtained, whether a material uncertainty
exists related to events or conditions that may cast significant doubt on the group’s ability
to continue as a going concern. If we conclude that a material uncertainty exists, we are
required to draw attention in our statutory auditor’s report to the related disclosures in
the consolidated financial statements or, if such disclosures are inadequate, to modify our
opinion. Our conclusions are based on the audit evidence obtained up to the date of our
statutory auditor’s report. However, future events or conditions may cause the group to
cease to continue as a going concern;

evaluate the overall presentation, structure and content of the consolidated financial
statements, and whether the consolidated financial statements represent the underlying
transactions and events in a manner that achieves fair presentation.

obtain sufficient appropriate audit evidence regarding the financial information of the entities
and business activities within the group to express an opinion on the consolidated financial
statements. We are responsible for the direction, supervision and performance of the group
audit. We remain solely responsible for our audit opinion.

We communicate with the audit committee regarding, amongst other matters, the planned scope
and timing of the audit and significant audit findings, including any significant deficiencies in
internal control that we identify during our audit.

We also provide the audit committee with a statement that we have complied with relevant
ethical requirements regarding independence, and we communicate with them about all
relationships and other matters that may reasonably be thought to bear on our independence,
and where applicable, related safeguards.

From the matters communicated to the audit committee, we determine those matters that were
of most significance in the audit of the consolidated financial statements of the current period
and are therefore the key audit matters. We describe these matters in our report unless law or
regulation precludes any public disclosure about the matter.

Other legal and regulatory requirements

Responsibilities of the supervisory board

The supervisory board is responsible for the preparation and the content of the directors’ report
on the consolidated financial statements, the statement of non-financial information attached to
the directors’ report on the consolidated financial statements and other matters disclosed in the
annual report on the consolidated financial statements.

Responsibilities of the statutory auditor

As part of our mandate and in accordance with the Belgian standard complementary to the
International Standards on Auditing (ISA) as applicable in Belgium, our responsibility is to verify,
in all material respects, the director’s report on the consolidated financial statements, the
statement of non-financial information attached to the directors’ report on the consolidated
financial statements and other matters disclosed in the annual report on the consolidated
financial statements, as well as to report on these matters.

Aspects regarding the directors’ report on the consolidated
financial statements and other information disclosed in the
annual report on the consolidated financial statements

In our opinion, after performing the specific procedures on the directors’ report on the
consolidated financial statements, this report is consistent with the consolidated financial
statements for that same year and has been established in accordance with the requirements of
article 3:32 of the Code of companies and associations.

In the context of our statutory audit of the consolidated financial statements we are responsible
to consider, in particular based on information that we became aware of during the audit, if
the directors’ report on the consolidated financial statements and other information disclosed in
the annual report on the consolidated financial statements, are free of material misstatements,
either by information that is incorrectly stated or otherwise misleading. In the context of the
procedures performed, we are not aware of such a material misstatement.

The non-financial information as required by article 3:32, § 2 of the Code of companies and
associations, has been disclosed in the directors’ report on the consolidated financial statements
that is part of the section on corporate social responsibility of the annual report (section “CSR
Report”). This non-financial information has been established by the company in accordance with
the United Nations’ Sustainable Development Goals (“SDG’s”). In accordance with article 3:80 § 1,
5° of the Code of companies and associations we do not express any opinion on the question
whether this non-financial information has been established in accordance with these SDG’s.

Statements regarding independence

Our audit firm and our network have not performed any prohibited services and our audit
firm has remained independent from the group during the performance of our mandate.

The fees for the additional non-audit services compatible with the statutory audit, as defined
in article 3:65 of the Code of companies and associations, have been properly disclosed and
disaggregated in the notes to the consolidated financial statements.
