Overview of our company,  
our strategy and 2022 achievements 

Forward with Purpose

THE GALAPAGOS GROUP

Letter from the CEO and Chairman

As I reflect on my first year as the CEO and
Chairman of the Board of Directors of Galapagos,
we can be proud of what we have achieved in a
very short time to embrace and execute on a new
R&D strategy for accelerated growth and a
sustainable future for our patients, our people, and
our shareholders.

2022 was characterized by major transformation
and change but our purpose remains unchanged:
through life-
transforming patient outcomes
changing science and innovation for more years of
life and quality of life.

By year-end, we implemented a therapeutic area
focused R&D model in immunology and oncology,
and we added new drug modalities to include CAR-
T cell therapy and biological capabilities. We aim to rebuild our portfolio with
transformational medicines, by accelerated innovation and shorter drug development
timelines.

Dr. Paul Stoffels

Through the acquisitions of CellPoint and AboundBio, we gained access to a
breakthrough, point-of-care CAR-T manufacturing platform, a clinical-stage CAR-T
oncology pipeline and research capabilities for novel, differentiated CAR-T constructs,
that together have the potential to deliver life-saving medicines to more patients, faster
and more efficiently. Through the two acquisitions, we also onboarded an excellent team
of cell therapy scientists and oncology experts.

We brought forward our CD19 CAR-T candidates manufactured at point-of-care in two
Phase 1/2 studies in patients with relapsed/refractory non-Hodgkin lymphoma and
chronic lymphocytic leukemia. We reported encouraging initial safety and efficacy Phase
1/2 results for both CAR-T candidates, which we believe demonstrate that through the
decentralized delivery model, a 7-day vein-to-vein, leukapheresis to infusion time, is
feasible. In addition, using non-frozen cells with a short culture time seems to result in a
promising safety and efficacy profile of the CAR-T therapy.

Over the next years, we aim to further broaden our CAR-T oncology portfolio and bring
additional differentiated CAR-T candidates into the clinic and to market, while further
advancing the ongoing Phase 1/2 studies in hemato-oncology, for which Phase 1 topline
results are expected around mid-2023.

THE GALAPAGOS GROUP

In addition, we remain fully committed to immunology, an area where there is still
significant unmet patient need and for which we have built deep scientific know-how
and expertise since our founding. With our programs targeting multiple modes-of-action
and drug modalities, we have a differentiated portfolio of preclinical to commercial
assets.

We are very proud that our first marketed medicine, Jyseleca®, an orally administered
JAK1 preferential inhibitor, continued to deliver solid in-market performance with a
growing European base and €87.6 million in net sales for the year 2022, reaching 18,000
patients with rheumatoid arthritis and ulcerative colitis across Europe.

Although the topline results from the Phase 3 DIVERSITY trial of filgotinib in Crohn’s
disease were not supportive to submit a Marketing Authorization Application in Europe
as the induction cohorts did not meet the co-primary endpoints, we were encouraged by
the confirmed safety profile and the efficacy results observed in the maintenance study
and will thoroughly review the full data to further help our understanding of this disease
and to support future research efforts.

We plan to further invest in our Jyseleca® franchise and later this year, we aim to start a
Phase 3 study in axial spondyloarthritis, a type of arthritis that typically begins between
the age of 20 and 40, and that causes pain and swelling in the spine and the joints that
connect the bottom of the spine to the pelvis.

Over the past year, we also made progress with GLPG3667, our selective TYK2 kinase
inhibitor, and we aim to start a Phase 2 study in dermatomyositis in the first half of 2023
and in systemic lupus erythematosus in the second half of 2023.

Finally, to accelerate time-to-patients, we have expanded our drug modality capabilities
in immunology, and recently announced that we aim to start clinical development with
a CD19 CAR-T candidate in refractory systemic lupus erythematosus in 2023.

2022 was characterized by major transformation and
change but our purpose remains unchanged:
through life-
transforming patient
changing science and innovation for more years of
life and quality of life.

outcomes

Beyond our renewed portfolio focus, our strategic transformation also includes
formalizing our Environmental, Social and Governance (ESG) ambitions. Over the course
of 2022, we completed a new materiality analysis, which allows us to further focus our
Sustainability ambitions in those areas that we believe are most material and where we
can make the greatest impact.

THE GALAPAGOS GROUP

With the new strategic direction, a new Executive Committee composition was
implemented with the retirement of Dr. Walid Abi-Saab and André Hoekema, and the
appointments of Valeria Cnossen, General Counsel, also responsible for Compliance &
Ethics, the Corporate Secretary Office and Intellectual Property, and Annelies Missotten,
Chief Human Resources Officer. In addition, our Board of Directors approved an updated
Corporate Governance Charter, which refers, amongst other updates,
to the
establishment of the Management Committee supporting the Executive Committee. As
a result, our senior leadership team has been further strengthened with key hires and
in Research, Development, Business Development and
internal promotions
Commercial. We continue to endeavor to attract experienced top talent across the
organization to execute on our strategy and accelerate innovation and time-to-patients
in our strategic focus areas of immunology and oncology.

During 2022, we focused on optimizing our organizational set-up and cost base.
Financially, we ended 2022 with a strong balance sheet of €4.1 billion in cash and current
financial investments, which provides us with the necessary means to look for additional
innovation to accelerate our R&D portfolio while progressing our internal
external
programs. We are confident that with our renewed focus to bring transformational
medicines to more patients, faster, we are well-positioned to deliver significant long-
term value for our shareholders.

Taking Galapagos on course for the future and embracing a new strategic direction was
challenging and hard work for all the teams. I would like to thank all our employees
for their commitment during the past year and for their relentless efforts to pioneer
for patients. I want to sincerely thank our shareholders for their trust and continued
commitment to stay with us on our journey.

We look forward with great optimism to a sustainable future as we continue to innovate
for patients to give them what matters the most: more time with family and friends. More
joy. Longer, healthier, better-quality lives.

Respectfully,

Dr. Paul Stoffels1
CEO and Chairman of the Board of Directors

THE GALAPAGOS GROUP

Our Strategy
We are a fully integrated biotechnology company united around a single purpose: to
transform patient outcomes worldwide through the relentless pursuit of life changing
science and innovation for more years of life and quality of life.

More than two decades ago, Galapagos was founded to discover new medicines with
novel modes of action. Since then, we identified numerous novel targets, generated an
R&D pipeline across multiple indications, entered into a significant strategic partnership
with Gilead, and successfully brought to market a medicine in two indications. We have
built a solid foundation based on strong financials, deep scientific and therapeutic
expertise in key areas, and a significant commercial footprint.

In 2022, we unveiled a new strategy to accelerate growth and value creation by reshaping
the way we innovate and operate. This strategy provides a clear path forward based on
three key pillars:

1. We shift from novel target-based discovery to patient-focused medical need
research and development with a focus on our key therapeutic areas of immunology
and oncology;

2. We build on our current capabilities and de-risk R&D through multiple drug
modalities, including CAR-T, small molecules and biologicals, and by focusing on
best-in-disease validated targets in our strategic therapeutic areas with shorter time-
to-patient potential;

3. We increase our business development efforts to complement our internal pipeline
and continue to work with our collaboration partner Gilead to bring more medicines
to patients worldwide.

Our differentiation is our entrepreneurship and integrated approach – patient-focused,
risk managed, collaborative and driven by medical need – combined with the scale
of our resources and our deep scientific expertise in key therapeutic areas. Together,
these enable us to significantly reduce time-to-results and accelerate delivery of
transformational innovations and medicines to patients.

Entered into the field of oncology through the combined acquisitions of CellPoint
B.V. (CellPoint) and AboundBio, Inc. (AboundBio), in all-cash transactions against
payment of an upfront amount of €125 million for CellPoint, with an additional
€100 million to be paid upon achievement of certain milestones, and against
payment of an amount of $14 million for AboundBio

Received various transparency notifications from EcoR1 Capital LLC and FMR LLC,
indicating that their shareholdings in Galapagos changed, crossing the 5% threshold,
to 5.2% and 5.9%, respectively, of the current outstanding Galapagos shares

Raised €6.7 million through the exercise of subscription rights

Announced changes to the Executive Committee: Dr. Walid Abi-Saab (Chief Medical
Officer) and Dr. André Hoekema (Chief Business Officer) retired from the company,
and Valeria Cnossen (General Counsel) and Annelies Missotten (Chief Human
Resources Officer) appointed as new members of the Executive Committee as of 1
January 2023. We anticipate announcing a Head of R&D and Executive Committee
member in the first half of 2023. Until such appointment, Dr. Paul Stoffels will act as
Head of R&D ad interim

Post-period events

The European Commission approved the recommendation of the PRAC to add
measures to minimize risks of serious side effects with all JAK inhibitors used for
chronic inflammatory disorders

Obtained reimbursement for Jyseleca® in UC in Italy and Denmark

Completed MANGROVE Phase 2 study with GLPG2737 in polycystic kidney disease
and decided not to-out-license the program due to lack of effect of GLPG2737 on
kidney volume and renal progression compared to placebo. The open-label
extension study was subsequently stopped

Data from SELECTION long-term extension (LTE) study of filgotinib in patients with
UC presented at annual ECCO congress showed that filgotinib 200mg maintained
a consistent safety profile observed in previous SELECTION studies. In addition,
symptomatic remission rates and health-related quality of life (HRQoL) improved in
patients with moderate to severe active UC who received filgotinib 200mg for nearly
four years

Poster presentation at annual EBMT-EHA congress demonstrating initial encouraging
safety and efficacy results from ongoing EUPLAGIA-1 Phase 1/2 study with a fresh
point-of-care manufactured CD19 CAR-T candidate, GLPG5201,
in patients with
relapsed/refractory chronic lymphocytic leukemia (rrCLL) and small lymphocytic
lymphoma (rrSLL), with or without Richter’s transformation (RT). All 7 out of 7 eligible
rrCLL patients, including 4 patients with RT, responded to treatment (Objective
Response Rate of 100%), and GLPG5201 showed an acceptable safety profile with
no cytokine release syndrome (CRS) higher than grade 2, or immune effector cell-
associated neurotoxicity syndrome (ICAN) observed

Announced topline results from the DIVERSITY study, a combined induction and
maintenance Phase 3 study of filgotinib in Crohn’s disease. While the co-primary
endpoints for filgotinib 200mg in the maintenance part of the study were met and the
observed safety profile is consistent with its known safety profile, the two induction
cohorts missed the co-primary endpoints of clinical remission and endoscopic
response at Week 10. Galapagos decided not to submit a Marketing Authorization
Application in Europe based on these topline data

(*) The number of employees on 31 December 2020 included 185 employees of Fidelta, which has been sold to Selvita on 4 January 2021.

Our net revenues in 2022 amounted to €505.3 million, compared to €484.8 million in 2021.

We reported product net sales of Jyseleca® in Europe in 2022 amounting to €87.6 million,
compared to €14.8 million last year.

Cost of sales related to Jyseleca® net sales in 2022 amounted to €12.1 million, compared
to €1.6 million in 2021.

Collaboration revenues amounted to €417.7 million in 2022, compared to €470.1 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 €174.4 million in
2022 (compared to €235.7 million in 2021). This decrease was due to a lower increase in
the percentage of completion, slightly offset by higher revenue recognition of milestone
payments, strongly influenced by the milestone achieved in 2022 related to the
regulatory approval in Japan for UC.

12
Galapagos NV Annual Report 2022

THE GALAPAGOS GROUP

The revenue recognition related to the exclusive access rights granted to Gilead for our
drug discovery platform amounted to €230.4 million in 2022 (compared to €230.6 million
in 2021). We also recognized royalty income from Gilead for Jyseleca® for €10.7 million
in 2022 (compared to €3.8 million in 2021). Additionally, we recorded in 2022 milestone
payments of €2.0 million triggered by the initial sales of Jyseleca® in the Czech Republic
and Portugal by our distribution and commercialization partner Sobi.

Our deferred income balance at 31 December 2022 includes €1.5 billion allocated to our
drug discovery platform that is recognized linearly over the remaining period of our
10-year collaboration, and €0.5 billion allocated to the development of filgotinib which
is recognized over time until the end of filgotinib’s development period.

Our R&D expenditure in 2022 amounted to €515.1 million, compared to €491.7 million in
2021. Depreciation and impairment costs in 2022 amounted to €54.5 million (compared to
€17.5 million in 2021). This increase was primarily due to an impairment of €26.7 million of
previously capitalized upfront fees related to our collaboration with Molecure on the dual
chitinase inhibitor OATD-01 (GLPG4716) and impairments of intangible assets related to other
discontinued projects recorded in 2022. Personnel costs increased from €165.2 million in
2021 to €190.1 million in 2022 related to increases in restructuring costs and accelerated non-
cash cost recognition for subscription right plans related to good leavers. This was partly
offset by a decrease in subcontracting costs from €251.1 million in 2021 to €214.9 million in
2022 following the evolution of our programs.

Our S&M and G&A expenses amounted to €292.5 million in 2022, compared to
€210.9 million in 2021. This increase was primarily due to the termination of our 50/
50 filgotinib co-commercialization cost sharing agreement with Gilead for filgotinib in
2022 which explains €59.7 million of the variance. The cost increase was also explained
by an increase in personnel costs of €26.6 million in 2022 compared to 2021, which are
related to an increase in our commercial work force driven by the commercial launch of
filgotinib in Europe, accelerated non-cash cost recognition for subscription right plans
related to good leavers and restructuring costs.

Other operating income (€46.8 million in 2022 compared to €53.7 million in 2021)
decreased, mainly driven by lower grant and R&D incentives income.

We reported an operating loss amounting to €267.5 million in 2022, compared to an
operating loss of €165.6 million in 2021.

Net financial income in 2022 amounted to €52.4 million, compared to net financial income of
€42.6 million in 2021. Net financial income in 2022 was primarily attributable to €41.3 million
of unrealized currency exchange gains on our cash and cash equivalents and current financial
investments at amortized cost in U.S. dollars, and to €6.9 million of positive changes in the (fair)
value of our current financial investments. The other financial expenses also had the effect of
discounting our non-current deferred income of €7.7 million. Net interest income amounted to
€11.1 million in 2022 as compared to €8.8 million of net interest expense in 2021.

We reported a group net loss in 2022 of €218.0 million, compared to a group net loss of
€103.2 million in 2021.

Cash, cash equivalents and current financial investments
Current financial investments and cash and cash equivalents totaled €4,094.1 million on
31 December 2022 as compared to €4,703.2 million on 31 December 2021.

Total net decrease in cash and cash equivalents and current financial investments
amounted to €609.1 million in 2022, compared to a net decrease of €466.1 million in
2021. This net decrease was composed of (i) €513.8 million of operational cash burn, (ii)
€153.4 million cash out from the acquisitions of CellPoint and AboundBio, net of cash
acquired, offset by (iii) €6.9 million positive changes in (fair) value of current financial
investments and €44.5 million of mainly positive exchange rate differences, and (iv)
€6.7 million of cash proceeds from capital and share premium increase from exercise of
subscription rights in 2022.

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 decrease or increase in our cash and cash equivalents
(excluding the effect of exchange rate differences on cash and cash equivalents), minus:

1.

2.

3.

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

the net proceeds or cash used, if any, in acquisitions or disposals of businesses; the
movement in restricted cash and movement in current financial investments, if any,
the loans and advances given to third parties, if any, included in the net cash flow
generated from/used in (–) investing activities

the cash used for other liabilities related to the acquisition of businesses, if any,
included in the net cash flow generated from/used in (–) operating activities.

Potential external impacts

COVID-19
Whilst the beginning of 2022 was globally marked by steeply increasing infection rates
mainly due to the spread of the highly infectious Omicron-variant, the situation
improved significantly as of the second quarter and the strict measures taken by local
governments to help prevent the spread of the COVID-19 virus and protect the physical
and mental health of our staff could gradually be loosened. We nevertheless continue to
monitor COVID-19 infection rates at global and local levels, and have systems in place
to react quicky where needed to guarantee business continuity. We report the following
impacts:

Staff
At Galapagos, we maintained the measures put in place by local governments to
help prevent the spread of the COVID-19 virus and protect the physical and mental
health of our staff, albeit that these measures were gradually loosened during 2022.
The majority of our research staff continued to work from the office/labs. For
teleworkable functions we continued the implementation of our hybrid working
model launched in 2021, in locations where the ongoing COVID-19 situation and
corresponding local governmental measures permitted us to do so. For those
employees coming to the office, we maintained stringent cleaning and sanitation
protocols. We further kept our global and site-specific business continuity plans up-
to-date and continued to take appropriate recommended precautions.

Development portfolio
We have a business continuity plan for our clinical development programs. We
closely monitor each program in the context of the current global and local situation
of the COVID-19 pandemic and the associated specific regulatory,
institutional,
government guidance and policies related to COVID-19. Within the boundaries of
these guidelines and policies, and in consultation with our contract research
organizations (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 its effect on
the study where necessary and to facilitate the interpretation and reporting of results.

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
impact on the relative
competitiveness of our commercial operations due to travel restrictions, nor have
the effects of COVID-19 impacted our ability to engage in market access discussions.
Nevertheless, healthcare systems are under pressure across Europe, increasing the
volatility in reimbursement procedures and cost containment measures, and
potentially reducing the number of new therapy options initiated by healthcare
providers.

Conflict in Ukraine

We currently have no clinical studies that are enrolling patients in Ukraine and
Russia. If our CROs experience significant or extended 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 pivotal studies such as DIVERSITY has
remained 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 CROs’ and our 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. This 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 conflict and the associated
specific regulatory, institutional, and government guidance and policies.

Going concern statement

To date, we have incurred significant operating losses, which are reflected in the
consolidated balance sheet showing €496.7 million accumulated losses as at
31 December 2022. We realized a consolidated net loss of €218.0 million for the year
ended 31 December 2022. Our existing current financial investments and cash and cash
equivalents of €4,094.1 million at 31 December 2022 will enable us to fund our operating
expenses and capital expenditure requirements at least for the next 12 months. The
Board of Directors 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 Board of Directors 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 Board of Directors 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
Executive Committee has set up internal risk management and control systems within
Galapagos. The Board of Directors 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

20
Galapagos NV Annual Report 2022

THE GALAPAGOS GROUP

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 34
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 2022 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.

Jyseleca® in rheumatoid arthritis (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 five major European markets (EU5)
is approximately €3.3 billion. Despite progress in the treatment of RA, there
remains a considerable unmet need as sustained remission remains rare.7

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.

To date there are 4 JAK inhibitors approved for the treatment of RA in the EU5, including
Jyseleca® (filgotinib) an orally administered preferential JAK1 inhibitor.

Below we present the RA market in the EU5.

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

In 2022, the Pharmacovigilance Risk Assessment Committee (PRAC) of the European
Medicines Agency (EMA) concluded its Article 20 safety review of all JAK inhibitors
approved in the EU for the treatment of inflammatory diseases and recommended the
harmonization of all labels. PRAC concluded that JAK inhibitors should maintain their
indication for the treatment of patients with RA who have responded inadequately to
or who cannot tolerate disease modifying anti-rheumatic drugs (DMARDs) therapy, and
for patients with UC who have responded inadequately to or who cannot tolerate
conventional therapy or biologics. PRAC also recommended all JAK inhibitor product
labels be updated to include a precautionary approach for use of JAK inhibitors in
patients with identified risk factors only if no suitable treatment alternative is available

(Section 4.4 of the product label – Warning and Precautions). On 11 November 2022,
the Committee for Medicinal Products for Human Use (CHMP), the scientific committee
of the EMA, adopted PRAC’s recommendation and on 10 March 2023, this decision was
approved by the European Commission.

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 programs.

31
Galapagos NV Annual Report 2022

PORTFOLIO

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, which enrolled subjects who completed either
the FINCH 1, FINCH 2, or FINCH 3 studies.

We and Gilead published integrated safety data from 7 RA studies in Annals of the
RheumaticDiseases(Winthrop etal.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 a similar incidence rate across
all dose groups. The data underscore the acceptable safety and tolerability profile of
filgotinib as monotherapy and in conjunction with MTX/csDMARDs8 in RA.

In preclinical animal toxicology studies, when administered at doses beyond its
approved dose in humans, filgotinib induced adverse effects on semen parameters.
Consequently, we and Gilead conducted dedicated male patient semen analysis studies
in UC and CD patients called MANTA, and RA, ankylosing spondylitis (AS), and psoriatic
arthritis (PsA) patients, called MANTA-RAy, concurrent to all Phase 3 programs.

In March 2021, we reported on the primary endpoint with the MANTA and MANTA-RAy
studies investigating the effect on semen parameters, which indicated 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. Subsequently, a Type II variation application was
submitted to the EMA in June 2022, supported by interim data on the primary, secondary
and exploratory endpoints at Week 13 and 26 for subjects who met a prespecified sperm
decrease at these timepoints (up to Week 52) from the MANTA and MANTA-RAy studies.
Following assessment of the interim data by the CHMP, it was concluded in the opinion
that the data did not reveal a difference between treatment groups in the proportion of
patients who had a 50% or more decrease from baseline in semen parameters at Week
13 (pooled primary endpoint: filgotinib 6.7%, placebo 8.3%) and at Week 26. Further,
CHMP concluded that the data did not show any relevant changes in sex hormone
levels or change from baseline in semen parameters across treatment groups. The CHMP
concluded that these clinical data were not suggestive of filgotinib-related effects on
testicular function. In October 2022, we received a positive CHMP opinion to update
the European label whereby the language in the section of the Special Warnings and
Precautions about the potential effect of filgotinib on sperm production and male
fertility was removed from the Summary of Product Characteristics (SmPC). In addition,
the MANTA/RAy studies were removed from the Risk Management Plan (RMP).

In 2022, we presented preliminary results from our first international, real-world arthritis
study, FILOSOPHY, FILgotinibObservational Study Of Patient Health-related outcomes,
at the American College of Rheumatology (ACR) Convergence 2022 meeting. The data
showed that filgotinib induced rapid relief in pain and fatigue as early as Week 1 as
well as improvements in disease activity9 at Month 1. These interim results were based

Jyseleca® in ulcerative colitis (UC)

UC is an inflammatory bowel disease (IBD) resulting in ulcerations and
inflammation of the inner layer of the colon and rectum. The current market
for UC treatments is estimated at ~€1.0 billion in the EU5.

Current treatment landscape in UC in Europe

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 UC for
some patients, 30% of patients do not respond to treatment,10 and 19% to 59% of initial
responders do not have a sustainable treatment response.11

Therefore, the medical need for improved treatment efficacy with additional treatment
options remains high.

The current market in Europe for UC is approximately €1.0 billion and is expected to grow
at a CAGR of 10% between 2020 and 2029.12

Safety and efficacy in the filgotinib UC development program

Filgotinib 200mg has shown favorable results in terms of rapid onset of action, efficacy,
safety, and tolerability from the SELECTION Phase 3 program in patients with moderate
to severe UC. The SELECTION Phase 3 data (Feagan etal. 2021) were published in The
Lancet.

Both in biologic-naïve and in biologic-experienced patients, a rapid onset of action for
filgotinib 200mg at Week 2, with a sustained effect up to 10 weeks, was observed in a pre-
specified exploratory analysis of the SELECTION study. The graph below shows the rapid
onset in both cohorts using the partial Mayo Clinic Score.

Furthermore in 2021, additional safety data from the SELECTION studies were presented
at the 16th European Crohn’s and Colitis Organisation (ECCO) 2021 virtual congress
(Schreiber etal.2021). Data were analyzed from the SELECTION induction, maintenance,
and long-term extension study with a cumulative treatment exposure of 1,207 patient
years for filgotinib 200mg versus 318 patient years for placebo, showing results
consistent with the original induction and maintenance studies, where filgotinib was
well tolerated in patients with moderate to severe active UC.

In 2022, we presented a set of new data from the SELECTION study and SELECTION long-
term extension study in UC at the ECCO 2022 annual conference. The key findings were:

1. Continued treatment with filgotinib for up to an additional 96 weeks in the long-
term extension study was effective in maintaining long-term improvements in UC
symptoms;

2. Retreatment with filgotinib upon interruption resulted in recovery of efficacy in most

patients and filgotinib was well tolerated with no new safety concerns;

3.

4.

Filgotinib’s efficacy profile was consistent and the safety profile acceptable
regardless of the age group, analysing patients up to 75 years of age; and

Filgotinib was able to achieve the high bar of efficacy as defined by a combined
endpoint of clinical and quality of life (QoL) remission, endoscopic and biomarker
improvement.

In 2023, we presented additional new analyses from the SELECTION program with
filgotinib at the annual ECCO congress. These include new analysis from the long-term
extension (LTE) study evaluating the safety and efficacy of filgotinib in UC for nearly
four years; an analysis of the prolonged benefit of filgotinib in UC; an analysis exploring
factors associated with the partial Mayo Clinic Score (pMCS) over time; and analysis of
the effect of filgotinib on anaemia in UC patients. Additionally, we presented pooled
data from five Phase 2/3 trials, and two long-term extension trials of filgotinib designed
to further understand the safety profile of filgotinib in UC and RA. Data from the
SELECTIONLTE study showed that filgotinib 200mg maintained symptomatic remission
and health-related quality of life (HRQoL) for up to approximately four years. Amongst
subjects who completed the study, the reduction in mean pMCS in SELECTION was
maintained up to LTE Week 144. In non-responders, mean pMCS decreased from LTE
baseline to Week 192. The results also showed that a high proportion of completers
(>80% of patients) and non-responders (>70% of patients) achieved remission according
to the Inflammatory Bowel Disease Questionnaire13. The safety profile of filgotinib 200mg
in the SELECTIONLTE study was generally consistent with the safety profile observed in
previous SELECTION studies, with no new safety signals observed.

Filgotinib in Crohn’s disease (CD)

CD is an IBD of unknown cause, which results in chronic inflammation of the
gastrointestinal (GI) tract with a relapsing and remitting course.

FITZROY Phase 2 program in CD

The FITZROY Phase 2 trial evaluated the efficacy and safety of filgotinib 200mg once-
daily 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 TheLancet(Vermeire etal.
2016), the FITZROY Phase 2 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.

DIVERSITY Phase 3 program in CD

Gilead initiated the Phase 3 DIVERSITY trial with filgotinib in CD in November 2016, and
following our amended collaboration agreement with Gilead, Galapagos became the
sole sponsor of DIVERSITY (including all development costs) and the long-term extension
study, and the parties completed the transfer of all data to Galapagos in March 2023.
Under the terms of the amended agreement, Gilead made a one-time payment of
$15 million to Galapagos.

DIVERSITY consisted of a combined (induction and maintenance), double-blind,
placebo-controlled Phase 3 trial, enrolling 1,374 biologic-naive and biologic-experienced
patients with moderate to severe active CD in 384 centers worldwide. The primary
objectives of the trial were to evaluate the safety and efficacy of filgotinib 100mg or
200mg, once-daily oral treatments, versus placebo.

The co-primary endpoints at Week 10 and Week 58 were clinical remission per Patient
Reported Outcome (PRO-2) and endoscopic response per Simple Endoscopic Score for
Crohn’s Disease (SES-CD). Clinical remission measured by the Crohn’s Disease Activity
Index (CDAI) was a key secondary endpoint in the induction and maintenance phase
of the study. Additional secondary endpoints were clinical remission and endoscopic
response (combined into a single endpoint on a patient level) at Week 10, clinical
remission and endoscopic response (combined into a single endpoint on a patient level)
at Weeks 10 and 58, sustained clinical remission and endoscopic response at Weeks
10 and 58, and 6-month corticosteroid-free clinical remission at Week 58 (see graphic
below).

Induction Cohort A included biologic-naïve (54%) and biologic-experienced (46%)
patients; induction Cohort B included biologic-experienced patients. In total, 33% of
patients in Cohort A and 52% of patients in Cohort B had failed treatment with 3 or more
biologic drugs.

On 8 February 2023, Galapagos announced topline results from the DIVERSITY study.

Both induction cohorts of the study failed to meet the co-primary endpoints of clinical
remission and endoscopic response for filgotinib, 100mg and 200mg once-daily. In the
maintenance phase of the study, a statistically significant higher proportion of patients
receiving filgotinib 200mg once-daily achieved the co-primary endpoints of clinical
remission (43.8% vs. 26.4%; p=0.0382) and endoscopic response (30.4% vs. 9.4%;
p=0.0038) compared to placebo at Week 58.

The safety observations of the study were in line with the underlying disease and were
consistent with the safety profile of filgotinib observed in previous studies across
indications.

Our TYK2 program: GLPG3667
GLPG3667 is an investigational reversible and selective TYK2 kinase domain inhibitor
that was discovered by us and evaluated in a Phase 1 healthy volunteer study in 2020.
The 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 exvivo
with several cytokines, including IFNα, to analyze the level of inhibition of inflammation,
including the effect on phosphorylated signal transducer and activator of transcription
(pSTAT) signaling as well as hematological parameters,
lipids and creatine-
phosphokinase (CPK) (see graphs below).

Following these results, we initiated a randomized, placebo-controlled, double-blind
Phase 1b study in 31 patients with moderate to severe plaque psoriasis. Patients were
randomized in a 1:1:1 ratio to a daily oral dose of GLPG3667 (low dose or high dose) or
placebo, for a total of 4 weeks.

In July 2021, we announced positive topline results demonstrating that GLPG3667 was
generally well tolerated with a positive response signal at Week 4 (see graph below):

At Week 4, four out of 10 patients in the high dose group had a Psoriasis Area and
Severity Index (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.

One subject in the low dose group interrupted participation in the study for one day
due to exacerbation of psoriasis. The majority of treatment related adverse events
(AEs) were mild in nature and transient. There were no deaths or serious adverse
events (SAEs) in this 4-week study.

Following these results, in 2022, we initiated the preparations for the Phase 2 studies with
GLPG3667 in dermatomyositis (DM) and systemic lupus erythematosus (SLE).

DM is the most common form of idiopathic inflammatory myopathies (IIM) and is
characterized by inflammatory and degenerative changes of the muscles and skin. IIMs
are a heterogenous group of rare autoimmune disorders primarily affecting the proximal
muscles. They are characterized by severe muscle weakness, muscle enzyme elevations,
inflammation on muscle biopsy, and extra-muscular manifestations. The quality of life of
patients with DM is impaired due to muscle weakness and pain, and skin disease activity.

PORTFOLIO

Our SIK program
The Salt-Inducible Kinases (SIK) belong to a novel class of targets with immune-
modulatory function discovered in an inflammation phenotypic cell assay with our
proprietary target discovery platform. The search, identification, and validation for this
novel class of targets started with the ambition to find novel druggable targets with
a differentiating mechanism-of-action to develop new therapeutic candidates
demonstrating an improved efficacy and safety profile relative to existing therapies.
Although significant progress has been made with novel therapies in recent years, for
instance in psoriasis, the unmet need to manage chronic inflammatory diseases related
to joints, the bowel, and other organs remains an important objective in public health.

The SIK family, which includes 3 members SIK1, SIK2, and SIK3, has been shown to
contribute to biologic pathways across multiple immune cells. SIK inhibition has the
potential to reduce the production of pro-inflammatory cytokines coupled with
enhanced production of immunoregulatory mediators. This unique mechanism-of-
action offers the potential to restore the immune balance that is typically out of balance
in autoimmune diseases, and differentiate product candidates from existing therapies
that predominantly act by suppressing the immune system.

We have been focusing our medicinal chemistry efforts on these targets, delivering over
5,000 synthesized molecules, and more than 11 different chemical series with different
SIK-isoform selectivity profiles. The first lead molecule from this program, GLPG3970,
a selective SIK2/SIK3 inhibitor, has demonstrated a response across several disease
models that has led to the investigation of a series of early-stage clinical trials in psoriasis
(CALOSOMA), UC (SEA TURTLE), and RA (LADYBUG). The topline results for GLPG3970
were announced in July 2021.

Thorough analysis of clinical endpoints and exploratory biomarker research has
confirmed meaningful signals of biological activity in psoriasis and UC patients despite
short treatment duration and suboptimal PK properties. A second candidate, GLPG4399,
selective for SIK3, was tested in a Phase 1 healthy volunteer study but will not be further
pursued for clinical development.

SIK portfolio outlook

From the clinical studies described above 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 and GLPG4399 further 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. We are currently
performing medicinal chemistry activities with the goal to start preclinical development
with a selective SIK inhibitor later in 2023.

CAR-T pipeline

GLPG5101 in refractory SLE
SLE is a female predominant,
relapsing and remitting autoimmune disease,
characterized by the formation of autoantibodies and immune complex–mediated
inflammation. This results in systemic progressive multiple organ damage, which is
associated with high morbidity and mortality.

Recently published data from a pilot study indicate that CAR-T cell therapy may have the
potential to achieve long-term drug-free SLE remission.15,16

Given our deep disease knowledge and expertise in the field of immunology and our
novel approach in the manufacturing of CAR-T therapies at the point-of care (see
ONCOLOGY section), we plan to initiate a Phase 1b patient study with our CD19 CAR-T
candidate, GLPG5101, later in 2023.

Oncology

Our differentiating approach
In 2022, we entered the field of oncology, CAR-T, and antibody-therapy research and
development through the acquisitions of CellPoint and AboundBio. The transactions
provide us with end-to-end capabilities in CAR-T therapy development and offer the
potential
for a paradigm shift in the space through the implementation of a
breakthrough, decentralized point-of-care manufacturing model, and cutting-edge fully
human antibody-based capabilities to design next-generation CAR-Ts and biologicals.

Point-of-care manufacturing
Despite continued progress with current CAR-T cancer therapies, long lead times, costly
central manufacturing and complex logistics continue to be limiting factors for large-
scale capacity and broad patient access.

To address important limitations of current CAR-T treatments, CellPoint (a Galapagos
company) has developed, in a strategic collaboration with Lonza, a novel decentralized
delivery model designed to manufacture non-frozen CAR-T therapies at the point-of-
care.

Through decentralized manufacturing, complex logistics and cryopreservation of the
cells can be avoided, and the average vein-to-vein time can be drastically reduced from
up to months for currently approved CAR-T therapies to 7 days with our CAR-T
candidates currently observed in our clinical trials.

Antibody engineering capabilities
AboundBio (a Galapagos company) has developed several very large, diverse human
antibody libraries in standard fragments of antigen binding (Fab), single-chain
variable fragments (scFv), and unique variable (VH) domain formats. The team can
rapidly (days to weeks) discover novel, high affinity, binders in multiple formats, engineer
them if needed to improve their developability properties, and convert them for multiple
uses including multi-specific, CARs, fusion proteins and antibody drug conjugates
(ADCs). The proprietary methodologies to build large fully-human antibody-based
libraries offer the potential to increase binder diversity, affinity and specificity; coverage
identifying a lead
of potential antigens; screening capacity; and probability of
therapeutic antibody candidate.

In the field of oncology, AboundBio provides unique research capabilities for next
generation CAR-T therapies that have the potential to deliver deeper and durable clinical
responses, as well as additional drug modalities beyond small molecules.

Our new generation of fully human, multi-specific CAR-T constructs have the potential to
transform patient outcomes through potentially more effective and longer-lasting care
options, even in the event of relapse after previous CAR-T-cell therapy. Together with
the decentralized CAR-T point-of-care manufacturing model, we aim to broaden patient
access and ultimately hope to change their lives.

GLPG5101: CD19 CAR-T in relapsed/refractory non-
Hodgkin’s lymphoma

Non-Hodgkin’s lymphoma (NHL) is a cancer originating from lymphocytes, a
type of white blood cell which is part of the body’s immune system. NHL can
occur at any age although it is more common in adults over 50 years old. Initial
symptoms usually are enlarged lymph nodes, fever, and weight loss. There are
many different types of NHL. These types can be divided into aggressive (fast-
growing) and indolent (slow-growing) types, and they can be formed from
either B lymphocytes (B cells) or in lesser extent from T lymphocytes (T cells)
or Natural Killer cells (NK cells). B cell lymphoma makes up about 85% of NHL
cases diagnosed in the US. Prognosis and treatment of NHL depend on the
stage and type of disease.

GLPG5101 is our second generation anti-CD19/4-1BB CAR-T product candidate,
administered as an intravenous infusion of a fresh product candidate in a single fixed
dose. Its feasibility, safety, and efficacy of point-of-care manufacturing are currently
being evaluated in the ATALANTA-1 Phase 1/2, open-label, multicenter study in patients
with relapsed/refractory non-Hodgkin lymphoma (rrNHL).

The primary objective of the Phase 1 part of the ATALANTA-1 study is to evaluate safety
and to determine the recommended dose for the Phase 2 part of the study. Secondary

objectives include assessment of efficacy and feasibility of point-of-care manufacturing
of GLPG5101. The dose levels that are evaluated in the Phase 1 part are 50x106 (DL1),
110x106 (DL2) and 250x106 (DL3) CAR-T cells. The primary objective of the Phase 2 part
is to evaluate the objective response rate (ORR) while the secondary objectives include
complete response rate (CRR), duration of response, progression free survival, overall
survival, safety, pharmacokinetic profile, and feasibility of point-of-care manufacturing.
Each enrolled patient will be followed for 24 months.

In December 2022, we presented initial data from the ATALANTA-1 Phase 1 study during
a poster session at the 64th Annual American Society of Hematology (ASH) Congress in
New Orleans, Louisiana. The initial results from 7 patients that were eligible for efficacy
evaluation (ATALANTA-1 Phase 1 study cut-off date: 8 November 2022) indicated that
a 7-day vein-to-vein time was feasible and demonstrated strong and consistent invivo
CAR-T expansion levels. Moreover, the initial efficacy results were encouraging with an
observed ORR of 86% and a complete response (CR) observed in all responding patients.
A duration of response of up to 7 months has been reported and follow-up is ongoing.
Two patients who received DL1 that progressed, after initial stable disease or CR
respectively, had a CD19-negative escape. No CD19-positive relapses have been
observed.

In the initial safety analysis of these 7 patients, adverse events were consistent with
the known toxicities of CD19 CAR-T treatment. No grade 3 or higher cytokine release
syndrome (CRS) or immune effector cell-associated neurotoxicity syndrome (ICANS) was
observed in any of the patients. At DL2, CRS grade 1 or 2 was reported in 4 patients and
ICANS grade 1 was reported in 3 patients. Patients at DL1 did not experience any grade of
CRS or ICANS. Dose-limiting toxicity (neutropenia grade 4 for >21 days) was observed in 1
patient (DL2) and the majority of grade ≥3 adverse events were hematological toxicities.

GLPG5201: CD19 CAR-T in relapsed and refractory chronic
lymphocytic leukemia

Chronic lymphocytic leukemia (CLL) is one of the chronic lymphoproliferative
disorders (lymphoid neoplasms). It is characterized by the excessive and
uncontrolled proliferation of functionally incompetent B lymphocytes from
lymphocyte leukemia (SLL) are
monoclonal origin. CLL and small cell
essentially the same type of B-cell non-Hodgkin lymphoma (NHL), with the
only difference the location where the primary cancer occurs. CLL affects B-
cells in the blood and bone marrow and SLL cancer cells are located in lymph
nodes and/or the spleen. Richter’s Transformation (RT) is an uncommon
clinicopathological condition observed in patients with CLL. It is characterized
by the sudden transformation of the CLL into a significantly more aggressive
form of large cell lymphoma, and occurs in approximately 2 – 10%16 of all
CLL patients. CLL/SLL usually follows an indolent course and is an incurable
disease. Patients who develop relapsed and refractory disease and become
resistant to new agents have a dismal prognosis and a high unmet medical
need for new therapeutic options such as CAR-T cells. With an estimated
incidence rate of 4.7 new cases per 100,000 individuals, CLL/SLL are the most
prevalent lymphoid malignancies and the most common forms of adult
leukemia in the US and in Europe17.

EUPLAGIA-1 is an ongoing Phase 1/2 study in heavily pre-treated patients with rrCLL and
rrSLL, with or without RT, to evaluate the safety, efficacy, and feasibility of GLPG5201, a
non-frozen CD19 CAR-T product candidate manufactured at point-of-care.

GLPG5201 is our second generation anti-CD19/4-1BB CAR-T product candidate,
administered as an intravenous infusion of a fresh product candidate in a single fixed dose.

Patients with CD19 rrCLL or rrSLL with >2 lines of therapy are eligible to participate, and
patients with RT are eligible regardless of prior therapy. The primary objective of the
Phase 1 part of the study is to evaluate safety and determine the recommended dose
for the Phase 2 part of the study. The dose levels that are evaluated in the Phase 1
part of the study are 35x106 (DL1), 100x106 (DL2) and 300x106 (DL3) CAR+ viable T cells.
The primary objective of the Phase 2 part of the study is to assess the ORR and the
secondary objectives include the analysis of the CRR, duration of response, progression
free survival, overall survival, safety pharmacokinetic profile, and feasibility of point-of-
care manufacturing.

We presented initial encouraging safety and efficacy data from the EUPLAGIA -1 Phase
1 study during a poster session at the EBMT-EHA 5th European CAR-T-cell Meeting in
Rotterdam in February 2023 (EUPLAGIA-1 Phase 1 study data cut-off date: 9 January
2023). At the moment of analysis on 9 January 2023, 7 patients diagnosed with rrCLL (4
patients of which have RT) were enrolled in the study (n=4 at dose level 1 (DL1); n=3 at
dose level 2 (DL2). All patients received GLPG5201 as a fresh infusion with a median vein-
to-vein time of 7 days.19

The initial results from these 7 patients that were eligible for efficacy analysis (EUPLAGIA
-1 Phase 1 cut-off date: 9 January 2023) indicated that a 7 day vein-to-vein time was
feasible and that the 'fresh' CAR-T product candidate demonstrated strong and
consistent in vivo CAR-T expansion levels. Moreover, the initial efficacy results were
encouraging with an observed ORR of 100%. A CR was observed in 6 out of 7 patients
(86%) and in all 4 patients with RT. A duration of response of up to 7.9 months has been
reported and follow-up is ongoing. Only 1 patient (DL1) progressed (progressive disease
after partial response, (PR)) and had a CD19-negative relapse with confirmed Richter’s
transformation.

In the safety analysis of these 7 patients, adverse events were consistent with the known
toxicities of CD19 CAR-T treatment. None of the patients experienced a cytokine release
syndrome (CRS) higher than grade 2 at both dose levels and no immune effector cell
associated neurotoxicity syndrome (ICANS) was reported. No dose limiting toxicities
(DLTs) were reported and the majority of grade ≥3 adverse events were hematological.
Only one serious adverse event was reported at DL2 with a patient experiencing a CRS
grade 2, but the event was resolved after 7 days.

The EUPLAGIA-1 study is continuing to enrol rrCLL and rrSLL patients in Europe,
including patients with RT, and we aim to provide Phase 1 topline results around
mid-2023.

GLPG5301: BCMA CAR-T in relapsed and refractory multiple
myeloma

Multiple myeloma (MM)
is typically characterized by the neoplastic
proliferation of plasma cells producing a monoclonal immunoglobulin. The
plasma cells proliferate in the bone marrow and may result in extensive
skeletal destruction with osteopenia, and osteolytic lesions with or without
pathologic fractures. The diagnosis of MM is made when one (or more) of
the following clinical presentations are present: bone pain with lytic lesions
discovered on routine skeletal films or other imaging modalities, an increased
total serum protein concentration with the presence of a monoclonal protein
in the urine or serum, and anemia, hypercalcemia or renal failure. The patient
may be either symptomatic or their disease may be discovered incidentally.

PAPILIO-1 is a Phase 1/2, open-label, multicenter study to evaluate the feasibility, safety,
and efficacy of point-of-care manufactured GLPG5301, our BCMA CAR-T product
candidate, in patients with relapsed/refractory multiple myeloma (rrMM).

GLPG5301 is a second generation anti-BMCA/4-1BB CAR-T product candidate,
administered as an intravenous infusion of a fresh product candidate in a single fixed
dose. Each enrolled patient will be followed for 24 months.

The primary objective of the Phase 1 part of the PAPILIO-1 study is to evaluate safety
and determine the recommended dose for the Phase 2 part of the study. Secondary
objectives of the Phase 1 part of the study include assessment of efficacy and feasibility
of point-of-care manufacturing of GLPG5301.

The primary objective of Phase 2 of the study is to evaluate the ORR while the secondary
objectives include assessment of CRR, duration of response, progression free survival,
overall survival, safety, pharmacokinetic profile, and feasibility of point-of-care
manufacturing.

We expect to start enrolling patients with rrMM in Europe in the second quarter of 2023.

Risk factors

Description of the risks  
investors should be aware of

Forward with Purpose

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 and UC in Europe, and Japan.

The commercial success of filgotinib and of any future products, if approved, will depend
upon the degree of market acceptance by physicians, healthcare payers, patients, and
the medical community. Market acceptance will depend on a number of factors, many of
which are beyond our control, but not limited to (i) the wording of the product label, (ii)
changes in the standard of care for the targeted indications for any product and product
candidate, (iii) acceptance by physicians, patients and healthcare payers of the product
as safe, effective and cost-effective and (iv) sales, marketing and distribution support.

We have limited experience in the sale or marketing of pharmaceutical products and
have build and continue to further develop a marketing and sales organization. We have
established our own sales force in several European countries. We expect to continue
to invest significant financial and management resources to continue to build these
capabilities and to establish a European commercial infrastructure or to enter into
collaboration arrangements with third parties to outsource the distribution or
commercialization, such as SOBI, our distribution and commercialization partner in
Eastern and Central Europe, Portugal, Greece, and the Baltic countries for filgotinib.
Recruiting and training a sales force is expensive and costs of creating an independent
sales and marketing organization and of marketing and promotion could be above those
anticipated by us. 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, which in turn would have a material adverse effect on our business,
financial condition, and results of operation.

Further, to the extent that Gilead is commercializing filgotinib in one or more
jurisdictions or a third party, such as Eisai, is commercializing filgotinib in one or more
jurisdictions, we are significantly dependent on their successful accomplishment of
commercialization efforts.

Coverage and reimbursement decisions by third-party payers may have an adverse
effect on pricing and market acceptance. Legislative and regulatory activity, including
enacted and future legislation, 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.

53
Galapagos NV Annual Report 2022

RISK FACTORS

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 Executive Committee; they are
discussed with the Board of Directors at least once per quarter, and the members of our
Board of Directors 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 and during
financial year 2022 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 filgotinib. We are also dependent on the
success of our other product candidates, such as GLPG3667, GLPG5101, GLPG5201 and
GLPG5301. During 2022, we shifted from novel target-based discovery to patient-focused
medical need research and development with a focus on our key therapeutic areas of
immunology and oncology. Filgotinib is approved for use in RA and UC in the European
Union, Great Britain and Japan. In addition, we are heavily investing in our early-stage
product candidate pipeline, including our SIK early-stage compounds, and these 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. Through the acquisitions of CellPoint and AboundBio, we gained access
to innovative, scalable, decentralized and automated point-of-care cell therapy supply
model as well as a fully human antibody-based therapeutics platform. We are heavily
investing in building our therapeutic area of oncology, whereby cell therapies are novel,
complex, and difficult to manufacture and require rigorous preclinical and clinical
testing, the results of which are uncertain.

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 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, including our CD19 CAR-T 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.

54
Galapagos NV Annual Report 2022

RISK FACTORS

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, including its financial condition, 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 of our product candidates are found to be unsafe or have a 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 enrollment. Patient enrollment 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 or unacceptable 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 and may adversely impact the viability of
our other product candidates or preclinical programs.

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. As
a result, filgotinib may have a labeling statement warning for male patients. Adjacent to
the filgotinib Phase 3 programs, we and Gilead were conducting dedicated male semen
analysis studies in CD and UC patients (MANTA) and in RA, PsA, and AS, patients (MANTA-
RAy). In March 2021, we reported on the primary endpoint with the MANTA and MANTA-
RAY studies. Following submission of a type II variation application to the EMA and
assessment of the data by the CHMP, a positive opinion has been issued in October 2022
by the CHMP to update the European label of filgotinib whereby the language in the

section of the Special Warnings and Precautions about the potential effect of filgotinib
on sperm production and male fertility was removed from the Summary of Product
Characteristics (SmPC). Such labeling statement warnings or changes of such labeling
statement warnings may harm the commercialization of our product candidates and our
business.

Even now when filgotinib has received regulatory approval or marketing authorization
in previously mentioned 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.

the European Medicines Agency’s (EMA) announced that

In February 2022,
its
Pharmacovigilance Risk Assessment Committee (PRAC) initiated 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. In November 2022, the EMA's Committee for Medicinal Products
for Human Use, CHMP, adopted the recommendation of the PRAC to add measures to
minimize risk of serious side effects with JAK inhibitors used for chronic inflammatory
disorders, followed by the approval of the European Commission on 10 March 2023.
If such safety review(s) result(s) in amendments to the marketing authorization for
filgotinib, or 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 or maintain 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. Even if we are able
to obtain orphan designation, we may not be the first to obtain marketing approval
for such indication due to the uncertainties associated with developing pharmaceutical
products. Orphan drug designation neither shortens the development time or regulatory
review time of a drug nor gives the drug any advantage in the regulatory review or
approval process.

We must establish and maintain a pharmacovigilance system, including a qualified
person responsible for oversight, submit safety reports to the regulators and comply
with the good pharmacovigilance practice guidelines adopted by the relevant regulatory
authorities. Failure to comply with these guidelines may harm our clinical trials or
regulatory process and by extension, our business.

If the FDA, EMA, or any other comparable regulatory authority approves any of our
product candidates, the manufacturing processes, distribution, adverse event reporting,

56
Galapagos NV Annual Report 2022

RISK FACTORS

storage, advertising, and recordkeeping for the product will be subject to extensive and
ongoing regulatory requirements, which currently is applicable for filgotinib. These
requirements include submissions of safety and other post-marketing information and
reports, registration requirements and continued compliance with current good
manufacturing practices, or cGMPs, and good clinical practices, or GCPs, for any clinical
trials that we conduct post-approval. Failure to comply with the aforementioned
practices may harm our clinical trials or regulatory process and by extension, our
business, financial condition and prospects.

Risks related to our financial position and
need for additional capital

We are an integrated biopharmaceutical company with a first and single commercial
launch and have not yet generated significant income. We have only very recently
commenced our transition from a clinical-stage to commercial-stage company. Until our
first commercial launch, our operations 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. Our losses resulted principally from costs incurred in research and
development, preclinical testing, clinical development of our product and our product
candidates as well as costs incurred for research programs, (pre-)commercial activities
and from general and administrative costs associated with our operations. 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 we will generate future profits from the sales of filgotinib, our
first product which was approved for commercialization in the European Union, Great
Britain and Japan. 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.

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, if approved.
Our ability to raise additional funds will depend on financial, economic and market
conditions and other factors, over which we may have no or limited control. 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 34 of the notes to the
consolidated financial statements.

57
Galapagos NV Annual Report 2022

RISK FACTORS

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 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. To the extent that Gilead is commercializing filgotinib in one or more
jurisdictions via a third party, such as Eisai for certain Asian markets, we are significantly
dependent on their successful accomplishment of commercialization efforts.

In addition, the terms of 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 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

58
Galapagos NV Annual Report 2022

RISK FACTORS

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.

We may not be successful in establishing future development and commercialization
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.

Developing pharmaceutical products, conducting clinical trials, obtaining regulatory
approval, 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

59
Galapagos NV Annual Report 2022

RISK FACTORS

or unaddressed 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.

In October 2021, we signed an agreement (as amended from time to time) with Sobi
regarding the distribution of Jyseleca®. Sobi acts as our distribution and
commercialization partner of filgotinib and will distribute the medicine in Central and
Eastern Europe, Greece, Portugal, and the Baltic countries. Launches and first sales of
filgotinib in the aforementioned countries trigger milestone payments by Sobi to us. We
are significantly dependent on Sobi's successful accomplishment of commercialization
efforts, and if, for any reason, the collaboration terminated, we may be unable to timely
or successfully find another distribution and commercialization partner, which may
interrupt or delay our commercialization efforts.

Through the acquisitions of CellPoint and AboundBio, we gained access to an innovative,
scalable, decentralized and automated point-of-care cell therapy supply model as well
as fully human antibody-based therapeutics platform and research capabilities for novel,
differentiated CAR-T constructs. To address important limitations of current CAR-T
treatments, CellPoint has developed, in a strategic collaboration with Lonza, a Swiss
manufacturing company for the pharmaceutical, biotechnology and nutrition sectors,
a novel decentralized delivery model designed to manufacture non-frozen CAR-T
therapies at the point-of-care. The platform consists of CellPoint’s end-to-end xCellit
workflow management and monitoring software and Lonza’s Cocoon®, a functionally
closed, automated manufacturing platform for cell therapies. Clinical studies with this
decentralized supply model have been approved by regulatory authorities in Belgium,
Spain, and the Netherlands. If, for any reason, the collaboration is terminated or is
otherwise materially changed and we are no longer entitled to use such technology
platform, then we may be unable to secure alternatives to such technology and, our
research, development or other efforts may be interrupted or delayed, and our financial
condition and results of operation may be materially adversely affected.

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

60
Galapagos NV Annual Report 2022

RISK FACTORS

trials in accordance with the applicable protocols and applicable legal, regulatory and
scientific standards, including Good Clinical Practices (GCPs). Regulatory authorities
enforce these GCPs through periodic inspections of trial sponsors, investigators and
clinical sites. If CROs do not successfully carry out their contractual duties or obligations
or meet quality standards, regulatory requirements or expectations, such as the
applicable GCPs, our clinical trials may be extended, delayed or terminated, the clinical
data generated in our clinical trials may be deemed unreliable and regulatory authorities
may require us to perform additional clinical trials before approving our marketing
applications 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. In addition to
GCPs, our clinical trials must be conducted with products produced under current Good
Manufacturing Practice (cGMP) regulations.

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 and innovation. Our competitors may
now or in the future 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.

These third parties compete with us in recruiting and retaining qualified scientific and
management personnel, establishing clinical trial sites and patient registration for
clinical trials, as well as in acquiring technologies complementary to, or necessary for,
the development of our product and product candidates. If we, our product and product
candidates or our technology platforms do not compete effectively, it is likely to have a
material adverse effect on our business, financial condition and results of operation.

61
Galapagos NV Annual Report 2022

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 and product candidates, as well as successfully defending these rights against
third party challenges. We will only be able to protect our product and 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, product, product candidates 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 and 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 and product candidates in all
countries and jurisdictions throughout the world would be prohibitively expensive, and

62
Galapagos NV Annual Report 2022

RISK FACTORS

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.

Risks related to our organization, structure
and operation

Our future success depends on our ability to retain the members of our Executive
Committee, and to attract, retain and motivate qualified personnel to develop our
business if we expand into the fields that will require additional skills and expertise,
including oncology. If we are not successful in attracting and retaining highly qualified
personnel, we may not be able to achieve our objectives and successfully implement
our business strategy, which could have a material adverse effect on our business and
prospects. Attractive development and training programs, adequate remuneration and
incentive schemes, and a safe and healthy work environment mitigate this risk as they,
among others, induce valuable qualified personnel to continue their employment or
services with our business.

We expect that if we continue to build our development, medical and commercial
organizations, including in the field of oncology, 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, expand our internal organization, systems,
controls and facilities to accommodate additional anticipated growth, and upon our
management developing and implementing strategies for our business to realize these
objectives. 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 have limited experience in the field of oncology, and continue to build our
therapeutic area of oncology. We expect to invest significant financial and management
resources to continue to build these capabilities and to establish such therapeutic area
within our business. In June 2022, we acquired CellPoint and AboundBio with the aim
to enter the space of oncology. Through such acquisitions, we believe we reinforced
our portfolio by gaining access to an innovative, scalable, decentralized and automated
point-of-care cell therapy supply model as well as fully human antibody-based
therapeutics platform. Cell therapies are novel, complex, and difficult to manufacture,
and we may not be successful in our efforts to develop and commercialize such
therapies,
in which case our financial condition and results of operation may be
materially adversely affected. The manufacturing processes that we use to produce
product and our product candidates for human therapeutics are complex, novel and
have not been validated for commercial use. Several factors could cause production
interruptions,
limitation) equipment malfunctions and facility
contamination. Problems with the manufacturing process, even minor deviations from

including (without

63
Galapagos NV Annual Report 2022

RISK FACTORS

the normal process, could result in product defects or manufacturing failures that can
result in lot failure or product liability claims.

We remain 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.

We must have a robust quality management system and team in place to ensure
(continued) compliance with current good laboratory practices, current good
manufacturing practices and current good clinical practices. If we are unable to comply
with these practices, this may harm our clinical trials or regulatory process and by
extension, our business.

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, and thus we have a
process to identify and mitigate threats by policies and procedures such as surveillance
of the buildings, annual appraisals and bonuses, and monthly management meetings.
Moreover, despite our efforts, the possibility of these events occurring cannot be
eliminated entirely, and there can be no assurance that any measures we take will
prevent cyber-attacks (including phishing attempts or e-mail fraud to cause payments or
information to be transmitted on an unintended recipient), security breaches or similar
attacks or breaches that could adversely affect our business.

We have to comply with applicable data privacy laws, including the European General
Data Protection Regulation (GDPR), which, among others, 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 personal data. 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
including the GDPR, and significant regulatory penalties, disrupt our
information,
operations and damage our reputation. Any of the foregoing could materially harm our
business, prospects, financial condition, and results of operation.

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 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

64
Galapagos NV Annual Report 2022

RISK FACTORS

requirements, which may give rise to liability, lead to the loss of trade secrets or other
intellectual property, 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. As our programs may require the use of
property rights held by third parties, the growth of our business will likely depend in part
on our ability to acquire, license-in or use these proprietary rights. We may be unable to
acquire or in-license any third-party proprietary rights that we identify necessary for our
drug candidates, for whatsoever reason. 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 adversely affect our activities,
financial situation and results. Such potential changes and their impact are monitored
carefully by our management and 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, the
French or the Dutch governments decide to eliminate, or reduce the scope or the rate of,
the research and development incentive benefits, either of which they 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 down to 3.75%. At 31
December 2022 we had €346.2 million of carry-forward innovation income deduction in
Belgium.

65
Galapagos NV Annual Report 2022

RISK FACTORS

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 from an agency of the
Flemish government to support various research programs and technological innovation
in Flanders. 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, which could adversely affect our ability to finance our research and
development projects.

We annually establish a detailed budget that is submitted to the Board of Directors
for review and approval. Our performance compared to the budget is continuously
monitored by our Executive Committee, and is discussed with the Board of Directors
at least once per quarter. For the establishment of our financial information, we have
processes and methods in place that enable the preparation of non-consolidated and
consolidated financial statements for our annual and quarterly reporting. Our
management reporting systems – which include an advanced integrated Enterprise
Resource Planning (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 information technology or
computer system failures. We may suffer data leaks, security incidents or become the
target of cyber-attacks, as a result of which our financial assets, confidential information
and/or intellectual property may be materially negatively impacted. We may not be
able to successfully protect our information technology or computer systems against
unauthorized access by third parties.

The occurrence of unforeseen or catastrophic events, including extreme weather events
and other acts of god or natural disasters, man-made disasters, electricity or
telecommunication interruption, geopolitical an and other economic and political
events or conditions (such as the armed conflict between Russia and Ukraine), or the
emergence of epidemics or diseases, 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, epidemics or diseases, 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, operations and financial performance cannot be precisely
determined or quantified, and will depend on future developments, but governmental
measures in order to control the spread of the virus 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,
continuing 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.

66
Galapagos NV Annual Report 2022

RISK FACTORS

The armed conflict between Russia and Ukraine could cause a disruption in our
operations, including clinical development activities and clinical trials. We currently have
no clinical studies that are enrolling patients in Ukraine and Russia.
If our CROs
experience significant or extended 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 pivotal studies such as DIVERSITY has remained 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 CROs’ and our
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. This 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
conflict and the associated specific regulatory, institutional, and government guidance
and policies.

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's control, such as, without limitation, the global economic situation,
the business development of competitors, and sector mergers and acquisitions; it is
difficult to mitigate these risk.

Economic risk due to failure in confidence
General public confidence about future economic conditions or performance of us,
our business, 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 would be
diluted.

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

67
Galapagos NV Annual Report 2022

RISK FACTORS

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 Conduct
and our Anti-Bribery and Anti-Corruption Policy.

Belgian law provisions
There are several provisions of Belgian company law and certain other provisions
of Belgian law, such as, without limitation, 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).

General statement about Galapagos’ risks

According to our current assessment and knowledge, we consider the major risks to be
manageable, and our going concern not to be endangered at the time of the current
report. Assuming no further deterioration of the global business,
financial, and
regulatory environment, we consider ourselves prepared to meet future challenges.

Committee, comprised of representatives from all departments throughout our organization, and
we completed a new materiality analysis. The materiality analysis informs our efforts and allows us
to focus our Sustainability ambitions on those areas where we can have the greatest influence and
make positive impact: Our Patients, Our People, Planet, and Trust & Transparency.

OurnewapproachtoSustainabilityisencapsulatedintheprinciple“Forward,Sustainably”,designed
to accelerate progress in our mission to bring more years of life and more quality of life to people
around the world. It’s about being ethical and innovative in everything we do, from research and
development, to workplace, culture, and leadership. We know that acting as a responsible and
sustainable business is key to our success as we continue to focus on the needs of patients who trust
and depend on us.

I am proud of all our employees who work hard to embrace the principles behind our Sustainability
pillars on a daily basis, and act as ambassadors for our company and values.

Respectfully,

CEO and Chairman of the Board of Directors

Our Materiality Assessment

Driven by our purpose to transform patient outcomes through life-changing science and
innovation, we recognize that our activities have an impact that reaches well beyond our
financial performance.

To determine our key goals and priorities, we conducted a new materiality assessment in
2022, allowing us to identify the topics that are most relevant to our internal and external
stakeholders. The analysis also enabled us to capture our current and potential impact
on society and the world, and to effectively track areas in view of emerging challenges
and opportunities.

To enhance the value of the materiality assessment, we updated the methodology we
applied for the 2018 materiality assessment and significantly increased the number
of stakeholders participating in the assessment. Externally we engaged with
representatives from patient organizations, patient experts, healthcare providers, supply
chain partners, our collaboration partners, and investors. Internally, next to the members
of our Executive Management and our Sustainability Steering Committee, all Galapagos

employees were given the opportunity to provide input regarding the materiality of
certain topics through a company-wide survey.

Internal and external stakeholders were invited to review a list of 35 potential material
topics and to identify five topics they found most relevant, five topics they found less
important for Galapagos and our core mission, and if any topic was missing.

The initial results further confirm the results from previous years with the top three pillars
clustered around People, Planet, and Trust & Transparency with one main change: the
desire to add a new pillar dedicated to Innovation for Patients.

We therefore adapted our focus areas and the four pillars as presented in the below

Our Ambition

Following our materiality assessment, in 2023, we aim to identify KPIs and set targets to
reach our 2028 call for action, as depicted in the graph below.

Our call for action by 2028

Add more years of life and
quality of life for patients

and inclusive,
and trusted organization

Be climate neutral

Our Sustainability Governance

In 2022, supported by the members of our Executive Committee, we established a
Sustainability Steering Committee, comprised of representatives from all departments
within our organization. The Sustainability Committee ensures that environmental,
social and governance considerations are fully integrated into the decision-making
processes,
including those related to the business strategy, key investments, and
performance. Our Sustainability Committee manages and coordinates the relevant
activities, and is responsible for the publication of related information and data. The
Committee consists of members of senior management and experts in the relevant
fields, including Compliance, Patient Advocacy, Legal, Finance, Environment, Health &
Safety (EHS), Procurement, Human Resources, Site Operations, Investor Relations, and
Communications.

The Executive Committee oversees the Sustainability Committee and approves both
the measures and operational structure related to Sustainability. In addition, our Board
of Directors, supported by the Audit Committee, oversees the Sustainability oversight
structure as well as the strategy for public disclosure with respect to ESG matters.

Reporting framework
To standardize our data collection, we use the United Nations Sustainable Development
Goals (SDGs), also known as the Global Goals, as our reference framework to link these
material aspects to areas of engagement. The SDGs were adopted by all United Nations
Member States in 2015 as a universal call to action to end poverty, protect the planet,
and strive to ensure that all people enjoy peace and prosperity by 2030.

We are preparing detailed reporting on our material aspects according to the Corporate
Sustainability Reporting Directive (CSRD) and anticipate reporting as of full year 2024 in
line with EU Sustainability Reporting Standards (ESRS).

The current sustainability report provides the non-financial information required by
articles 3:6 § 4 and 3:32 § 2 of the Belgian Companies Code. For a discussion on risks,
please see the section on Risk factors in this Annual Report.

We have identified two core SDG goals where we believe we can make a difference, as
well as six enabling SDG goals. Together they will help us to execute on our commitment
to our four Sustainability pillars.

The table below links our material aspects and engagement areas to selected aspects of
the SDG framework:

to advancing
transformational medicines for diseases with significant unmet medical needs. Our
commitment to improving the lives of people worldwide is reflected from our innovative
research to our product development and providing patient access to our innovative
medicines.

That is why we value continued improvement in our research, development, and access
approaches, in an unwavering focus on outcomes with the greatest value to patients.
It is why we embrace change and support disruptive innovation, aim to build a culture
of responsible innovation throughout the entire medicine lifecycle and are committed
to enable the safe and appropriate use of our medicines as they are prescribed by
physicians and used by patients in the medical practice.

We focus our development efforts on areas where we have deep expertise and map out
the critical path towards market with the goal of reducing the time it takes to bring new
medicines to the patients who need them.

At every stage of the patient journey, we aim to pioneer for patients by working in
close partnership with patients and patient organizations, starting with the design of our
clinical studies.

SUSTAINABILITY REPORT

We therefore co-developed our Patient Partnership Charter in 2021 with the patient
community to set our commitment to engage with patients. Using the Charter as a
guideline we defined our roadmap to:

strengthen our relationships with academia, patient groups, and industry partners;

include patient and investigational site expectations into the design of late phase
clinical trials with the aim of making participation easier and more rewarding:

identify measurable performance indicators; and

assess our performance during clinical development as well as after.

We believe our research and development efforts can help advance science beyond
the patients we serve. Our plain language summaries of our data make them easily
understandable, and our commitment to our Open Access publishing enables us to
communicate clearly and effectively to all our stakeholders.

Furthermore, since 2020, we actively participate as a member
in the 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.

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. Through a bi-yearly performance cycle, we aim to ensure an open and
supportive professional environment. Performance bonuses and, for many employees,
share-related opportunities, help drive sustainable performance and commitment, and
reward employees for their contributions to our success. As part of the performance
cycle, we also increased our investment in the development and engagement of our
employees, by focusing on learning, coaching, and training opportunities. Additionally,
we introduced “How Are You?” conversations to stimulate an open dialogue between
manager and employee as well as departmental “Talent Talks” focused on development
opportunities within and outside the different departments.

The benefits we offer vary from country to country, based on local customs and statutory
conditions. We enriched our employee benefits at both the international and country
level:

Enhanced pay for performance linkages in our Year-End compensation review and
related programs;

Broad-based annual stock-based awards to drive further alignment between the
company and all our employees;

Roll-out of further family leave policies;

Improvements to various local benefits offerings ranging from enhanced time off to
improved medical provision; and

The implementation of mobility programs to encourage environmentally sound
transportation behaviors.

Further to our Environmental, Health and Safety (EHS) policy, we provide safe and
healthy working conditions aiming to prevent any work-related personal harm. Our

2022 HIGHLIGHTS

For the fourth year in a row we are included in the 2023
Bloomberg Gender-Equality Index. The Bloomberg Gender-
Equality Index is an objective measure that tracks gender
equality across five pillars: leadership & talent pipeline,
equal pay & gender pay parity, inclusive culture, anti-sexual
harassment policies, and external brand. The list
encompasses 484 companies headquartered in 45
countries and regions

We hired and onboarded 179 new colleagues, including our new CEO, bringing the
headcount to 1,338 people. Given the era of talent and the scarcity in the market
for many profiles, we increased our focus on proactive talent sourcing, created an
internship program to attract and grow young talents and launched a compelling
employer brand campaign, with the tagline #IFoundMyPurpose, that consisted of
podcasts and videos with employee testimonials

A revised strategy was set-out soon after onboarding our new CEO, redesigning the
company around our two strategic therapy areas, immunology and oncology, as core
value drivers. As part of this strategic expansion in oncology, we led the due diligence,
onboarding and integration of new colleagues at CellPoint and AboundBio, in the
Netherlands and the U.S. respectively. Another part of the transformation was the
reset towards a fit-for-purpose organization, and we announced a restructuring
potentially affecting 200 positions. We organized face-to-face sessions on three
locations to coach employees in dealing with change and insecurity. In total, over
150 employees attended these sessions and more than 85% of the participants rated
them as ‘helpful’

We celebrated the United Nations’ Health and Safety at Work Day on 28 April by
organizing a wide range of well attended, site–specific awareness and training
sessions related to first aid, the use of Automated External Defibrillators, ergonomic
workplace design, fire and explosion prevention, etc.

Belgian companies are required by law to conduct a wellbeing survey and we
launched the RAPSi20 survey at beginning of 2022 for our staff employed at our
headquarters in Mechelen. 74% of our employees participated and overall wellbeing
met or exceeded the Belgian benchmark in the vast majority (88%) of the questions
included in the survey. In addition, we conducted a separate Employee Engagement
Survey among our commercial affiliates for which we reported overall engagement
rates above Global & Industry Benchmarks. The level of employee motivation,
commitment to the company’s mission, and strong relationships between employee
and line manager stood out

to the Planet

We are conscientious: Our Commitment to the Health of Our
Planet
The health of the planet and the health of people are interconnected.

To support our environmental ambitions, we have set the clear aspiration to become
carbon neutral by 2028. We have defined a 5-year roadmap on how to achieve this
goal, applying a sound and credible mix of carbon reduction and carbon
compensation projects. We are also embracing the circular economy, reducing waste,
and reusing or recycling materials where and when we can.

As the reduction of green-house gas emissions is an essential success factor in our
approach, our reduction roadmap entails three pathways. These include initiatives to

Systematically replace any fossil fuels by renewable energy sources used in our
buildings and car fleet;

Improve energy efficiency of our operations; and

Drive behavioral change and raising environmental awareness among our staff.

As an example, we are seeking BREEAM (Building Research Establishment Environmental
Assessment Method) and WELL (eco-friendly initiative focusing on human health and
welfare enterprise) certifications for our newly constructed buildings.

For instance, in Oegstgeest, The Netherlands, we obtained a BREEAM Excellent and a
WELL Gold certification for our new building and our garden gather native plants, trees,
shrubs, as well as beehives and insect hotels.

Our
Commitment to
Trust & Transparency

We are transparent: Our commitment to Trust &
Transparency
Doing business ethically is about being a responsible corporate citizen. The standards
we apply and decisions that we make every day are thoughtful and considered, ensuring
that we act in the best interest of patients, people, and the planet. It is about building
trust by setting measurable goals, communicating them clearly, and being open and
transparent about the progress we are making to deliver on them – both where we are
doing well and where we need to put more effort.

We prioritize ethical management of our supply chain, vendors and partners. Just as
we seek partners and suppliers who share our commitment to the planet, we also
ensure they share our commitment to quality and ethical business practices. We refined
our third-party onboarding through an enhanced risk assessment framework and due
diligence on quality, IT security, data protection and privacy, compliance and ethics,
and environment. We also continually evaluate our supply chain to ensure continuity
and optimization of costs, and we provide a consistent framework for partners and
employees that outlines clear and comprehensive guidance for ethical and transparent
behavior across our company.

To ensure our products meet the highest quality standards, we work with qualified and
certified (GMP-licensed) distributors that ensure that all processes related to receipt,
storage, handling and final distribution to customers comply with the regulations. We
regularly audit our GxP manufacturers and distributors.

We work to protect our people, patients, our planet, and our business by taking every
reasonable measure to ensure that we all operate in accordance with the applicable
regulations and standards as well as compliance laws.

We nurture a culture of voice that encourages every one of our employees to share ideas
and that ensures that our employees feel protected if they believe something needs to
be corrected.

We also nurture a culture of integrity, in which our employees, partners and suppliers
value and take accountability for upholding our standards.

We operate in an environment where the safety of patients is paramount. We currently
have one medicine, Jyseleca®, on the market in Europe and Japan. We have
implemented a pharmacovigilance system designed to monitor the safety of Jyseleca®
and to detect any change to the benefit/risk profile.

To protect our patients, our partners, employees, and other stakeholders, we
implemented state of the art security monitoring systems, data and cyber security and
governance frameworks.

We explicitly forbid animal neglect or cruelty. We have also implemented practices that
demonstrate our commitment and responsibility to refine, reduce and replace testing
involving the use of animals to the greatest possible extent, and we will continue to
research, promote, and further implement alternative methods. From a scientific
perspective, it is not yet possible to examine all the complex interactions a potential
treatment triggers in a living organism without animal testing. Additionally, there is
the legal framework for medicine development with regulatory authorities worldwide
requiring new medicines be evaluated in animals to ensure the quality, safety, and
efficacy of these products before granting approval. However, we are committed to
continue to implement 3R (Replacement, Reduction, and Refinement) principles. Our
Animal Welfare Committee supported more than 15 major 3R initiatives in 2022,
including six new initiatives. Our Animal Welfare Policy was endorsed by senior
management and is requested from all our Research and Development suppliers.
Assessment of animal welfare was also reinforced through several key actions, including
laboratories,
requirement of animal standards for
verification of the implementation of these practices, detailed review and update of the

Reporting on EU Taxonomy

EU Taxonomy 2022 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 company with more than 500 employees, Galapagos is in scope of the EU
Taxonomy Regulation26. For reporting over the fiscal year 2022, Galapagos has to disclose
the proportion of its 2022 turnover, capital expenditures (‘CapEx’), and operating
expenses (‘OpEx’) eligible and aligned under the EU Taxonomy on sustainable activities.

The EU Taxonomy 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:
(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;

(i) climate change mitigation;

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; the determination of eligibility happens on the basis of the
description of activities. An eligible activity becomes Taxonomy-aligned when it meets
all the aforementioned overarching criteria, which includes that such activity should
substantially contribute to at least one of the six environmental objectives. However,
only activities that contribute to the two first environmental objectives (climate change
mitigation (“CCM”) and climate change adaptation (“CCA”)) have been formally adopted
so far.

Following thorough analysis of the EU Taxonomy legal framework27, we do not consider
our core business activities, being discovering, developing and commercializing
innovative medicines, to be in scope of the Climate Delegated Act. Our core economic
activities qualify as EU Taxonomy non-eligible economic activities, and do not
substantially contribute neither to CCM nor to CCA, and are therefore are not EU
Taxonomy-aligned.

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.

87
Galapagos NV Annual Report 2022

SUSTAINABILITY REPORT

For the determination of turnover, CapEx and OpEx during this analysis, we use the
reported data in the 2022 consolidated financial statements included in this report:

Turnover covers all business activities of Galapagos at 31 December 2022 and the
denominator can be reconciled with the 2022 IFRS total net revenues recognized
pursuant to €505.3 million and disclosed in note 6, being the revenues from
commercial sales and collaboration activities.

CapEx consists of additions to tangible and intangible assets during the financial
year 2022 considered before depreciation, amortization and any re-measurements
recognized by Galapagos pursuant to IAS 38. The denominator (total CapEx) can
be reconciled with the sum of the lines ‘Impact of acquisitions of businesses’ and
‘Additions’ disclosed in notes 13 and 14 (total €170.0 million) of the consolidated
financial statements. The majority of CapEx is associated with licences, rights,
technology and in-process R&D acquired through a business combination, and
building costs of new office spaces in Belgium and the Netherlands.

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. These costs are for the majority associated with our R&D
expenditure, as disclosed in note 7 (total €515.1 million).

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 as a result
each are 100% Taxonomy not eligible, therefore not EU Taxonomy-aligned.

Please refer to the Annexes to this Annual Report for the disclosure on KPIs of non-
financial undertakings as required by Annexes II of the Climate Delegated Act.

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.

(hereinafter "Galapagos NV" or the "Company") 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 of which entered into force on 1
January 2020.

For the reporting year beginning on 1 January 2022, the 2020 Code was our reference
code. On 26 April 2022, as a consequence of the introduction of a one-tier governance
structure at the Company through the amendment of our Articles of Association,
Galapagos NV’s Board of Directors approved an updated Corporate Governance Charter.
On 21 March 2023, our Board of Directors approved an amendment to the Corporate
Governance Charter. The amended Corporate Governance Charter refers to the
establishment of the Management Committee supporting the Executive Committee,
allows the same person to be Lead Non-Executive Director and Chairman of the Audit
Committee, provides that the Lead Non-Executive Director is member or Chairman of
the Nomination Committee and clarifies that the Lead Non-Executive Director supports
the Chairman in ensuring the prevention and managing of conflicts of interests involving
potentially a director. Galapagos NV’s Corporate Governance Charter is available on
our website (www.glpg.com). The Corporate Governance Charter applies in addition
to the applicable laws and regulations, Galapagos NV’s Articles of Association and the
corporate governance provisions included in the Belgian Companies Code and the 2020
Code. The Corporate Governance Charter describes the main aspects of corporate
including its governance structure, the terms and
governance at Galapagos NV,
functioning of the Board of Directors (including its Board Committees), the Executive
Committee and the rules of conduct.

For the reporting year beginning on 1 January 2022, the Board of Directors strove to
comply with the rules and recommendations of the 2020 Code. At the same time, the
Board of Directors is of the opinion that certain deviations from the rules and
recommendations of the 2020 Code were justified, in view of our activities, our size, and
the specific circumstances in which we operate. In such cases, which are mentioned in
this corporate governance statement, we apply the “comply or explain” principle as set
forth in the 2020 Code. Reference is made to the About the Board of Directors and
Nomination Committee sections below.

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.

From 1 January 2022 until 26 April 2022, Galapagos NV had a two-tier governance
structure as provided by the Belgian Companies Code, with two governance bodies: the
Supervisory Board and the Management Board. The Supervisory Board was responsible
for the general policy and strategy of the Company, and had all powers which are
specifically reserved for it under the Belgian Companies Code. The Supervisory Board
also supervised the Management Board. The Management Board exercised all powers
which are not reserved for the Supervisory Board in accordance with the Belgian
Companies Code,
including the management of the Galapagos group and the
supervision of actual performances compared to strategic goals, plans and budgets.

As from 26 April 2022, Galapagos NV adopted a one-tier governance structure as
provided by the Belgian Companies Code, with the Board of Directors replacing the
(former) Supervisory Board and the Executive Committee replacing the (former)
Management Board.

CORPORATE GOVERNANCE

The role of the Board of Directors is to pursue sustainable value creation by the
Company, by setting the Company’s strategy, putting in place effective, responsible and
ethical leadership and monitoring the Company’s performance. The Board of Directors is
the ultimate decision-making body, with the overall responsibility for the management
and control of the Company, and is authorized to carry out all actions that are necessary
or useful for the realization of the Company’s object with the exception of those reserved
to the Shareholders’ Meeting by applicable law. The Board of Directors also supervises
the Executive Committee. The Board acts as a collegiate body.

The Board of Directors has delegated certain powers to manage the Company to the
Executive Committee, led by our Chief Executive Officer. The Executive Committee is
responsible and accountable to the Board of Directors for the discharge of
its
responsibilities. Furthermore, the Board of Directors has delegated the day-to-day
management of the Company to one Executive Committee member, i.e. our Chief
Executive Officer.

In order to efficiently fulfill its tasks and in view of the size and activities of the Company,
the Board of Directors has established an Audit Committee, a Remuneration Committee
and a Nomination Committee. These Board Committees serve in an advisory capacity
to the Board of Directors on the matters delegated to them respectively as set forth in
the applicable laws and the Company’s Corporate Governance Charter. Until 2 May 2022,
there was a combined Nomination and Remuneration Committee. As from 2 May 2022,
our Board of Directors has set up a separate Nomination Committee and Remuneration
Committee.

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

Changes to our Board of Directors
The tenure of Katrine Bosley and Howard Rowe as members of our Board of Directors
came to an end on 26 April 2022. We thank Katrine Bosley and Howard Rowe for their
contributions and commitment to the Company over the years.

About the Board of Directors
Galapagos NV’s Board of Directors consists of at least five and no more than nine
members. At least three members of our Board of Directors are independent. On 31
December 2022, the Board of Directors consisted of nine members, five of whom are
independent within the meaning of article 7:87 of the Belgian Companies Code and
provision 3.5 of the 2020 Code.

Except for Stoffels IMC BV (permanently represented by Dr. Paul Stoffels), all members of
the Board of Directors are non-executive directors.

The members of our Board of Directors are appointed at the Shareholders’ Meeting
upon the proposal of the Board of Directors, for a renewable term of up to four years.
Members of the Board of Directors whose mandate has come to an end may be re-
appointed. When a position on the Board of Directors becomes vacant, the remaining
members may temporarily fill the mandate by cooptation and until appointment of a
new Board member at the next Shareholders’ Meeting. Each member of the Board of
Directors appointed as such by the Shareholders’ Meeting shall complete the tenure of
the member of the Board of Directors he/she replaces, unless the Shareholders’ Meeting
decides otherwise. The Nomination Committee nominates, for approval by the Board
of Directors, candidates to fill vacancies as they arise, and advises on proposals for
in each case taking into account the
appointment originating from shareholders,
Company's needs and the selection criteria determined by the Board of Directors. In
proposing candidates, particular consideration will be given to gender diversity and
diversity in general, as well as complementary skills, knowledge and experience.

Provision 3.12 of the 2020 Code recommends that, in case of a one-tier governance
structure, (a) there should be a clear division of responsibilities between the person
presiding over the Board of Directors (the Chairman) and the person assuming executive
responsibility for running the company’s business (the CEO), and (b) the Chairman of
the Board of Directors and CEO should not be the same individual. In deviation from
this provision, Stoffels IMC BV (permanently represented by Dr. Paul Stoffels), who is our
CEO since 1 April 2022, was also appointed as Chairman of the Board of Directors as of
26 April 2022. In light of the prevailing circumstances, the Board of Directors considered
that the one-tier governance structure and the combined role as CEO/Chairman allows
the Company to fully leverage the leadership of Dr. Paul Stoffels, and to efficiently set
and implement the Company's direction and strategy (including in the field of business
development). Furthermore, the Board of Directors is of the opinion that such combined
role has a positive impact on the functioning and efficiency of the Board, as well as on
the provision of information to the Board of Directors, allowing the Board of Directors
to monitor the Company’s (and group’s) performance more effectively during 2022. In
order to ensure sufficient balance, the Board adopted a counter balancing governance

102

CORPORATE GOVERNANCE

structure that includes the election of a Lead Non-Executive Director acting as the
principal liaison between the Chairman and the non-executive members of the Board of
Directors (see also below). Dr. Rajesh Parekh was appointed as the Lead Non-Executive
Director of the Company, effective as of 2 May 2022. Effective as of March 21, 2023,
Jérôme Contamine is appointed as the new Lead Non-Executive Director of Galapagos,
replacing Dr. Rajesh Parekh. The Lead Non-Executive Director is entrusted with the
responsibilities and powers set out in the Corporate Governance Charter of Galapagos
NV.

Companies Code (i.e. an amendment of the mangement agreement between Galapagos NV and Stoffels IMC BV). Having a conflict of
interests concerning the proposed amendment, Stoffels IMC BV (permanently represented by Dr. Paul Stoffels) left the meeting before the
deliberation and vote concerning this agenda item took place. Afterwards, he rejoined the Board meeting for the next agenda items. Thus,
this meeting was taken into account for his attendance rate during the 2022 financial year.

In 2022, the following persons, as identified in the table above, were members of the
Board of Directors (former Supervisory Board): Stoffels IMC BV (permanently represented

Baker (member since 26 April 2022). On 31 December 2022, Mary Kerr, Peter Guenter,
Elisabeth Svanberg, Jérôme Contamine and Dan Baker were independent members
of the Board of Directors within the meaning of article 7:87 of the Belgian Companies
Code and provision 3.5 of the 2020 Code. In 2022, the Board of Directors was therefore
composed of a majority of independent directors.

At the Annual Shareholders’ Meeting of 26 April 2022, the tenure of Howard Rowe and
Katrine Bosley as members of the Board of Directors came to an end.

In 2022, the Board of Directors thus consisted of three women (except between
1 January 2022 and 26 April 2022 when the Board consisted of four women), and six
men (except between 1 January 2022 and 26 April 2022 when the Board consisted of four
men), representing five different nationalities and different age categories.

During 2022, Galapagos NV complied with its obligations with respect to gender
diversification in the Board of Directors as set forth in article 7:86 of the Belgian
Companies Code, and the Board of Directors 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 all members of the Board of Directors are

The role of the Board of Directors is to pursue the long-term success and sustainable
value creation by Galapagos NV. The Board of Directors does so by assuming the
authority and responsibilities assigned to it by Belgian corporate law, the Company’s
Articles of Association, and the Corporate Governance Charter, and by combining
entrepreneurial leadership with appropriate risk assessment and management. Each of
the directors’ expertise and experience is exemplified by the varied professional activities
they carry out and offices they hold. During its meetings in 2022, the Board of Directors
dealt with matters pertaining to, among other things, our strategy and growth, the entry
into the field of oncology through the combined acquisitions of CellPoint and
AboundBio, the evaluation of other business development opportunities, the search
and recruitment of our new Chief Executive Officer, the implementation of our new
governance model, the implementation of our new strategic direction to accelerate
innovation and time-to-patients (including a focus on key therapeutic areas of
immunology and oncology, and an expansion of drug modalities beyond small
molecules, such as biologicals and CAR-T), clinical trial results, commercialization of
Jyseleca®, and regulatory developments, convening of the Shareholders’ Meeting and
preparation of resolutions to be submitted for approval to the shareholders, the creation
of new subscription rights for the benefit of the personnel of Galapagos NV and its
subsidiaries, and review and approval of our financial reporting.

In 2022, fourteen meetings took place physically, through written resolutions, telephone
conferences or videocalls to discuss specific matters, including three meetings in the
presence of a notary public (relating to the issuance of Subscription Right Plan 2022
(A), Subscription Right Plan 2022 (B), Subscription Right Plan 2022 BE, Subscription
Right Plan 2022 RMV and Subscription Right Plan 2022 ROW). Two of the meetings in
the presence of a notary public were attended by Peter Guenter and Rajesh Parekh via
telephone conference. The third meeting in the presence of a notary public was attended
by Mary Kerr and Elisabeth Svanberg via telephone conference. All other directors were
represented by proxy at the meetings in the presence of a notary public. The attendance
rate for the other Board meetings, as identified in the table above, was as follows: Rajesh
Parekh: 91%; Stoffels IMC BV (permanently represented by Dr. Paul Stoffels) (member
since 26 April 2022): 100%; Howard Rowe (member until 26 April 2022): 100%; Katrine
Bosley (member until 26 April 2022): 100%; Mary Kerr: 91%; Peter Guenter: 91%; Jérôme

2022): 100%; Daniel O’Day: 100%; Linda Higgins: 100%, and Elisabeth Svanberg: 100%.
The overall attendance rate was 98%. Stoffels IMC BV (permanently represented by Dr.
Paul Stoffels) recused itself from deliberation and decision-making on one agenda item
because of a conflict of interests,
in accordance with article 7:96 of the Belgian
Companies Code, as set forth in further detail in the section titled Conflict of interests
and related parties.

The Board of Directors acts as a collegial body. A formal evaluation of the Board of
Directors (formerly Supervisory Board) and its Board Committees was carried out in
September 2021. Each member of the Board of Directors provided feedback through
individual assessment forms. The results were presented on an aggregate basis by the
Secretary adinterimof the (former) Supervisory Board (currently Board of Directors), and
served as a basis for discussion by the full (former) Supervisory Board. This evaluation
specifically addressed the functioning of the (former) Supervisory Board, the size and
composition of the (former) Supervisory Board, the interaction between the (former)
Supervisory Board and the (former) Management Board (currently the Executive
Committee), and the functioning of the Board Committees. A new Board evaluation
exercise was performed in the second half of 2022. As part of this exercise, the Board of
Directors' composition was reviewed, a composition matrix was created, and interviews
were held with Board members on the functioning and composition of the Board of
Directors.

Pursuant to the Company’s Corporate Governance Charter and as a counter balancing
governance structure for the combined CEO & Chairman role within the Board, the
Board of Directors appointed a Lead Non-Executive Director. The Lead Non-Executive
Director is also automatically the Vice-Chairman of the Board of Directors. The Lead Non-
Executive Director is entrusted with the responsibilities and powers set out in Galapagos
NV’s Corporate Governance Charter, including, but not limited to, serving as principal

Rights attached to Galapagos shares
Each share (i) entitles its holder to one vote at the Shareholders’ Meetings; (ii) represents
an identical fraction of the share capital and has the same rights and obligations and
shares equally in the profit of Galapagos NV; and (iii) gives its holder a preferential
subscription right to subscribe to new shares, convertible bonds or subscription rights in

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. This
general authorization will expire on 12 November 2024; and

117
Galapagos NV Annual Report 2022

CORPORATE GOVERNANCE

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 was 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 could, however, only be
used in a number of specific circumstances and upon a resolution of the Board of
Directors that all independent directors (within the meaning of article 7:87 of the
Belgian Companies Code) approve. This specific authorization expired on 30 May
2022.

In 2022, Galapagos NV’s Board of Directors made use of the right to increase the capital
in the framework of the authorized capital on three occasions:

On 13 January 2022, in connection with the issuance of Subscription Right Plan
2022 (A) under which a maximum of 30,000 new shares could be issued for a total

On 31 December 2022, an amount of €24,889,284.17 still remained available under the
general part of the authorized capital.

of Directors may, if in Galapagos NV’s interest, restrict or cancel the shareholders’
preferential 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.

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.

118
Galapagos NV Annual Report 2022

CORPORATE GOVERNANCE

Within the framework of the powers granted to it under the authorized capital, the
Board of Directors may also increase Galapagos NV’s capital as specified in its Articles of
Association.

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

or represented at such meeting. The aforementioned rules are also applicable to the
acquisition of shares of Galapagos NV by its subsidiaries.

The Board of Directors has currently not been authorized by an Extraordinary
Shareholders’ Meeting to purchase or sell its own shares.

On 31 December 2022, 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.

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.

to take appropriate measures to avoid the disclosure of 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 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

appointed to our Board of Directors. The Board members Daniel O’Day and Linda
Higgins are representatives of Gilead.

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.

Company subscribed to 6,828,985 new Galapagos shares at a price of €140.59 per share,
which included an 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, both of whom are still directors of Galapagos NV today.

On 22 October 2019, our Extraordinary Shareholders’ Meeting approved the issuance of 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 of the
Company. 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.

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 of the Company. The initial
Warrant B 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 from 23 August
2019, subject to and upon approval by the Company's Shareholders’ Meeting, Gilead
Therapeutics A1 Unlimited Company will be issued a warrant with substantially similar
terms, including exercise price, to the initial Warrant B. This subsequent Warrant B will
expire on the earlier of (i) the date that is five years after the fifth anniversary of the
closing and (ii) the date that the warrant is issued.

Gilead and Gilead Therapeutics A1 Unlimited Company are subject to certain standstill
restrictions until 10 years following the closing, which occured on 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 beginning on 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 for a period of five
years until 22 August 2024. In 2022, Gilead and Galapagos agreed to amend the share
subscription agreement for conformity with the change from a two-tier to a one-tier
governance system by Galapagos.

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 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 the marketing authorization
holder for filgotinib outside of Europe,
including in Japan, where filgotinib is co-
marketed with Eisai. The transfer was subject to applicable local legal, regulatory and
consultation requirements. Most activities transferred to Galapagos by 31 December
2021 and we completed the transition during 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, (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 from Gilead to Galapagos, and (3) the Second
Amended and Restated License and Collaboration Agreement of 24 December 2021,

123
Galapagos NV Annual Report 2022

CORPORATE GOVERNANCE

amending and restating the existing collaboration agreement, which went into 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, a safety study in men with moderately
to severely active UC and CD to assess semen parameters while taking filgotinib, and its
long-term extension, from Gilead 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 continued 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 CD, 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 was intended to be completed by 30 June 2022 and was completed by March
2023. From 1 April 2022, Galapagos is 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 LTE from Gilead to Galapagos, which transfer
was largely completed by 31 December 2022.

All commercial economics on filgotinib in Europe transferred 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. 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, an additional €75 million
in April 2021 and €50 million in 2022. Furthermore, Gilead made a one-time payment of
$15 million to Galapagos in 2022 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 $275 million and sales-based milestone payments of up to
$600 million.

On 28 March 2022 filgotinib was approved by the Japanese Ministry of Health, Labour
and Welfare for UC, for which we received a $20.0 million (€18.2 million) regulatory
milestone payment from Gilead in May 2022.

In March 2022, Gilead and Galapagos agreed to further amend the collaboration by
adding the following countries to the Galapagos territory: Andorra, San Marino, Monaco,
and Vatican City.

Our remuneration policy

A revised remuneration policy is applicable as of 1 January 2022, and has been approved
by the 2022 Shareholders' Meeting. Such document is available on our website.

Remuneration report

Introduction: remuneration report 2022

Galapagos’ remuneration policy
Galapagos’ current remuneration policy was prepared in accordance with the Belgian
Companies Code and approved by Galapagos’ shareholders at the 2022 Annual
Shareholders’ Meeting with 64.40% of shareholder votes. The policy became effective as
from 1 January 2022 and applies for the reporting year beginning on 1 January 2022. In
this report we will look back at 2022 and reflect on how the progress made with regard
to our 2022 corporate objectives has influenced the remuneration outcomes.

Galapagos encourages an open and constructive dialogue with its shareholders to
discuss its approach to governance, including remuneration, and to understand what
they consider best practices. The disclosure in the remuneration report reflects the input
received from Galapagos’ shareholders over the years as well as developments in the
legislative framework, including the introduction of the comparison table and pay ratio.

The objective of our remuneration policy is to attract, motivate and retain diverse,
qualified and expert individuals who are key in order to achieve our strategic and
operational objectives. Our further goals are to be competitive in the appropriate market
by benchmarking against relevant peer groups, incentivizing performance at the highest
possible level, allowing for differential rewards according to individual performance, not
to discriminate on any grounds other than performance, and to reinforce an open, fair,
consistent and equitable culture.

Peer group and benchmarking
Galapagos’ remuneration policy strives to take into account relevant benchmarks with
appropriate peer companies and, for the Executive Committee members, the group’s
performance management system is also considered. Over the years, our Nomination
and Remuneration Committee has conducted such benchmarking exercise and has
been supported by external advisors during the performance of its responsibilities.

125
Galapagos NV Annual Report 2022

CORPORATE GOVERNANCE

Currently a new benchmarking exercise for Executive Committee roles is ongoing in the
light of our strategic transformation and reviewed R&D strategy, focused on immunology
and oncology with the aim to transform patient outcomes through life-changing science
and innovation. Galapagos is at a pivotal juncture in its history to reset its strategic path,
and is building an oncology franchise where attracting and retaining highly specialized
expertise in an international labor market is essential to succeed.

The peer groups currently determined by the Remuneration Committee consist of
publicly listed biotechnology companies with a comparable market capitalization in
the U.S. and biotechnology and pharmaceutical companies with a broadly comparable
market capitalization in Europe,
in both cases taking into account the R&D and
commercialization profile and business model to the extent possible. The Committee
considers both these reference points given the talent pool for the Executive Committee
extends to both Europe and the U.S., with the majority of our competitors based in
the U.S. These benchmarks will support the Remuneration Committee in its decision
making, also taking into account Galapagos’ strategic context and requirements,
company performance, individual performance and skills as well as broader workforce
considerations. Finally, the committee also determined to maintain a view to a Bel20
(the benchmark stock market index of Euronext Brussels) general industry peer group
(excluding financial services companies) to ensure an understanding of the local Belgian
listed market given the location of our headquarters; however, given the international
nature of our executive leadership and specific sector considerations, it is not the
reference to inform our pay policy.

Remuneration structure components
The remuneration of the members of the Board of Directors consists of (i) a fixed annual

entitled to any additional remuneration for its mandates of Chairman of the Board of
Directors or of any Committee.

127
Galapagos NV Annual Report 2022

CORPORATE GOVERNANCE

Cash remuneration
The members of the Board of Directors receive a fixed annual cash amount, irrespective
of the number of Board meetings that are held during the year. The remuneration of
the directors does not contain a variable part. These Board fees are paid in quarterly
installments at the end of each calendar quarter.

For the financial year 2022 the previous Chairman of the Board of Directors, Mr. Rajesh
Parekh, received a total cash remuneration of €67,072 and the other members €50,000
each (if in function for the entire year). In addition, Committee membership entitles the
directors to an additional €15,000 in cash and Committee chairmanship to an additional
€20,000 in cash (if in function for the entire year).

Equity based remuneration
In accordance with provision 7.6 of the 2020 Code, Galapagos also grants members of
the Board of Directors an equivalent to a remuneration in shares, being a cash amount
equal to the respective Board member’s annual cash remuneration whereby the net
portion (after taxes) should be used to acquire Galapagos shares. During the financial
year 2022, the members of the Board of Directors received the following additional cash
compensation: for the previous Chairman of the Board of directors €100,000 (prorated
amount if not in function for the entire year) and for the other members €50,000 each
(prorated amount if not in function for the entire year), in each case subject to the
requirement to use the net amount (after taxes) to acquire Galapagos shares. One former
Board member waived the equity-based remuneration for the financial year 2022. These
share purchases resulted in the number of shares identified in the table above. The
shares that each director so acquires are to be held until at least one year after the
Board member leaves the Board of Directors and at least three years after the time of
acquisition. These latter payments make up the equivalent of an equity component of
the members of the Board of Directors’ remuneration, as recommended by the 2020
Code.

As of 2020 Galapagos does not grant any subscription rights to members of the Board of
Directors (non-executive directors).

focused on the discovery, development

Our ambition is to continue establishing ourselves as a successful commercial stage
biopharmaceutical
and
commercialization of innovative medicines in areas of unmet medical needs with the
aim to improve the lives of people suffering from serious diseases. In order to achieve
this long-term goal, we are striving for continued innovation in our research efforts
and sound clinical progress year over year, while maintaining a healthy cash position.
Considering our new strategy, we shifted from novel target-based discovery to patient-
focused medical need research and development with a focus on our key therapeutic
areas of immunology and oncology.
In addition, our corporate development and
business goals aim to foster the growth of the company and value creation for all
shareholders, including via business development opportunities, to complement our
internal pipeline. Finally, our commercial development goal intends to continue to build
our filgotinib franchise throughout Europe,
in order to become a commercially
successful biopharmaceutical company which brings transformational medicines to
patients (subject to having obtained governmental approvals).

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

Taking all considerations into account, Galapagos’ policy is to grant a number of
subscription rights each year based on a consideration of each Executive Committee
member’s role, individual performance for the performance year as well as individual
impact on long-term value creation.

The Remuneration Committee is responsible for evaluating the Executive Committee
members’ performance in accordance with the principles set out above. The
Remuneration Committee is composed exclusively of non-executive directors and a
majority of its members qualify as independent Board members. This helps prevent the
occurrence of conflicts of interest regarding the implementation of the remuneration
policy in relation to the Executive Committee members. The members of the Executive
Committee are not invited to take part in any discussions of the Remuneration
Committee related to their own individual remuneration.

The level of achievement of the objectives for the CEO is assessed at the end of each
year by the Remuneration Committee and discussed and finally established by the Board
of Directors. The level of achievement of the objectives of the other members of the
Executive Committee is assessed by the CEO at the end of the year, discussed by the
Remuneration Committee and finally established by the Board of Directors.

Galapagos’ policy is to grant a number of long-term incentives based on the individual
performance for the performance year while also considering individual (future) impact
on long-term value creation. Bonuses consist both of a short-term cash component and
a long-term RSU component. Members of the Executive Committee were also offered
subscription rights in 2022.

Under our remuneration policy, the CEO’s cash bonus can be maximum 75% of its base
salary. The aggregate cash bonuses of the other members of the Executive Committee
can be maximum 50% of the aggregate base salaries. An equivalent number of RSUs will

131

CORPORATE GOVERNANCE

be granted to the CEO and the other members of the Executive Committee under the
RSU Annual Long-Term Incentive Plan.

(a) Short-term variable remuneration

Upon recommendation of the Remuneration Committee, the Board of Directors
determined an overall achievement of 80% (out of a maximum of 100%) against the 2022
corporate objectives. In arriving at this determination, the Board considered that some
of the objectives were not achieved, some had been met and some overachieved. This
determination included an evaluation of activities that were either stopped, started or
modified by the strategic reset that occurred during the course of the year following the
appointment of our new CEO.

The performance highlights over 2022 included: (i) the acquisition of CellPoint &
AboundBio, propelling us into the field of oncology, and next generation CAR-Ts and
biological drug modalities, (ii) Jyseleca® performance beyond expectations, with actual
full year net sales of €87.6 million, at the upper end of the guidance of €80 – 90 million
and above the initial 2022 net sales guidance of €65 – 75 million – reaching 18,000
patients in Europe and reimbursed for RA in 15 countries, and for UC in 11 countries,
(iii) regulatory progress, including completion of the PRAC article 20 procedure for all
JAK inhibitors in Europe to treat certain inflammatory disorders, including filgotinib, and
separately, a positive CHMP opinion on the type II variation application for filgotinib
based on the MANTA and MANTA-RAy studies, resulting in a label update of the European
label for RA and UC, (iv) the launch of our new Forward, Faster strategy involving the
transformation of our R&D organization into a fit-for-purpose R&D organization, built
around our key therapeutic areas oncology and immunology and (v) initial encouraging
safety and efficacy results from ongoing Phase 1/2 study in refractory/relapsed non-
Hodgkin’s lymphoma with CD19 CAR-T candidate, GLPG5101, manufactured at point-of-
care.

The 80% corporate funding level is applicable to the wider Galapagos workforce for the
corporate component of their bonus funding, including the members of the Executive
for the CEO upon recommendation of the
Committee. The Board of Directors,
Remuneration Committee and for the other Executive Committee members upon
proposals of the CEO, considered this level of funding, as applied to the wider workforce,
together with individual performance of Executive Committee members in order to
determine the individual cash bonus outcomes for 2022 set out in the total remuneration
table above: Stoffels IMC BV, permanently represented by Dr. Paul Stoffels (€337,500; 60%
of 2022 base salary)28, Mr. Bart Filius (€230,000; 45% of 2022 base salary), and Mr. Michele
Manto (€164,300; 47% of 2022 base salary). Our former Executive Committee members
have the following cash bonus outcomes: Dr. Andre Hoekema (€100,000; 31% of 2022
base salary) and Dr. Walid Abi-Saab (€165,000; 38% of 2022 base salary). These 2022 cash
bonuses will be paid in April 2023. With the exception of the retired Chief Business Officer
and Chief Medical Officer, each of the members of the Executive Committee will be
granted an equivalent number of RSUs under the 2023 RSU Annual Long-Term Incentive
Plan as long-term variable remuneration.

28

The conflict of interest procedure within the meaning of article 7:96 of the Belgian Companies Code has been applied for the 2022 bonus
decision for Stoffels IMC BV, a full disclosure shall happen in the annual report for the financial year 2023.

(b) Long-term variable remuneration

In 2022, our (new) CEO, Stoffels IMC BV (permanently represented by Dr. Paul Stoffels),
was offered 1,000,000 subscription rights under Subscription Right Plan 2022 (B) as a
sign-on remuneration given the strategic importance of hiring Dr. Stoffels as CEO, his
knowledge and experience in the pharmaceutical sector and leadership capabilities. He
accepted all the granted subscription rights.

The members of the Executive Committee were offered new subscription rights under
Subscription Right Plan 2022 BE and each accepted all subscription rights granted as
per the following: Mr. Bart Filius: 68,000 subscription rights, Dr. Walid Abi-Saab: 32,000
subscription rights and Mr. Michele Manto: 24,000 subscription rights. Further reference
is made to the Equity components of the remuneration section, which contains, among
others, a description of the 2022 grant of subscription rights.

The total remuneration table above sets forth the value of the number of RSUs vested
and paid out in 2022 for each member of the Executive Committee. 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 2022, there were RSU vestings under five different RSU plans: Plan 2019.I,
Plan 2019.II, Plan 2019.III, Plan 2020.II and Plan 2021.IV. The pay-outs to the Executive
Committee 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 Executive Committee members in 2022,
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 members of the Executive Committee in 2019, 2020, 2021 and 2022.

Pension and other components
In addition, the members of the Executive Committee enjoy a number of benefits in line
with our remuneration policy such as a retirement plan, insurance programs (covering
life insurance, disability, travel insurance and health), company cars and the provision
of certain tax 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 Executive Committee member are
summarized in the total remuneration table above.

Equity components of the remuneration

Subscription rights awarded, exercised or expired
In 2022, we issued subscription right plans for the benefit of employees of the group
and of Executive Committee members: Subscription Right Plan 2022 (A), Subscription
Right Plan (B), Subscription Right Plan 2022 BE, Subscription Right Plan 2022 RMV and
Subscription Right Plan 2022 ROW. Each subscription right gives the right to subscribe

133
Galapagos NV Annual Report 2022

CORPORATE GOVERNANCE

for one new Galapagos share. Our CEO was offered new subscription rights under
Subscription Right Plan 2022 (B) and the members of the Executive Committee were
offered new subscription rights under Subscription Right Plan 2022 BE, subject to
acceptance. The final number of accepted subscription rights under Subscription Right
Plan 2022 (B) was enacted by the notary deed of 25 March 2022 and under Subscription
Right Plan 2022 BE by notary deeds of 7 July 2022 and 2 September 2022. The table
below sets forth the numbers of subscription rights offered and accepted by the CEO and
each other member of the Executive Committee in 2022, respectively under Subscription
Right Plan 2022 (B) and Subscription Right Plan 2022 BE.

The main characteristics of the subscription right plans offered to the members of the
Executive Committee 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.

Under Subscription Right Plan 2022 (B), the subscription rights have a lifetime of eight
years and an exercise price of €50.00. The subscription rights under Subscription Right
Plan 2022 (B) 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 2026.

Under Subscription Right Plan 2022 BE, the subscription rights have a lifetime of eight
years and an exercise price of €57.46. For all the beneficiaries under the Subscription
Right Plan 2022 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 2026 and are not transferable.
The table below sets forth the main characteristics for subscription right plans issued
during previous years and 2022.

As from 1 January 2020, Galapagos no longer grants any subscription rights to members
of the Board of Directors, 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, members of the Board
of Directors were granted subscription rights and hence the table below also contains
disclosures for Board members.

No subscription rights expired for members of the Board of Directors or Executive
Committee in 2022.

The table below sets forth the subscription rights outstanding and exercisable per 31
December 2022 for the (former) members of the Board of Directors or Executive
Committee, the subscription rights awarded to the (former) Executive Committee

RSUs offered to, vested or expired for the Executive
Committee members
In 2022, the Executive Committee members were offered new RSUs under 2022 RSU
Annual Long-Term Incentive Plan, except our new CEO who joined per 1 April 2022,
and under the 2022 RSU Retention Plan, subject to acceptance. The members of the
Executive Committee accepted all RSUs offered to them, except for one member. The
grant under the 2022 RSU Annual Long-Term Incentive Plan is the grant equivalent to
the actual bonus for 2021 and this RSU grant will vest in full three years after the offer
date. The grant under the 2022 RSU Retention Plan has a four-year vesting period, with
25% vesting each year and a first vesting date on 1 May 2023. With the exception of the
RSUs offered to and accepted by Stoffels IMC BV (permanently represented by Dr. Paul
Stoffels), the RSUs are not transferable. The table below sets forth the total number of
RSUs offered and accepted by each Executive Committee member during 2022: Stoffels
IMC BV (permanently represented by Dr. Paul Stoffels): 74,408 RSUs, Mr. Bart Filius: 61,442
RSUs, Dr. Walid Abi-Saab: 37,274 RSUs and Mr. Michele Manto: 27,354 RSUs.

The main characteristics of the RSU plans for the Executive Committee 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 Executive Committee 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.

(1) The directors’ remuneration overview contains for the CEO, other Executive Committee members and directors 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 the CEO and the other Executive Committee members, being the annual base salary, cash bonus and (if any) exceptional bonus.
(3) The second row shows the total remuneration of the CEO and the other Executive Committee members, 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 2022 the exercise price of the Subscription Right Plan 2022 BE is compared
with the average share price as quoted on Euronext Brussels and Amsterdam during the financial year 2022.

(4) CEO as of 1 April 2022.
(5) CEO until 31 March 2022.
(6) The other Executive Committee members during financial year 2022 are Mr. Bart Filius, Dr. Walid Abi-Saab (until 31 December 2022), Dr. Andre Hoekema (until 31 October 2022) and

Mr. Michele Manto. Their remuneration over the five year period is included under the “Other Executive Committee members”.

(7) The first row shows the total cash remuneration of each member of the Board of Directors, being the board fees.
(8) The second row shows the total remuneration of each member of the Board of Directors, including equity-based remuneration such as subscription rights granted during the year. As

from 1 January 2020, Galapagos no longer grants any subscription rights to members of the Board of Directors.

(9) Chairman of the Board of Directors until 26 April 2022.
(10) Director until 26 April 2022.
(11) Director as of 30 April 2019.
(12) Director as of 28 April 2020.
(13) 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.

(14) 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.
(15) 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.

(16) 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 2022 year-end process, the actual annual figures for employees had not been finalized by the date of this report. Therefore, 2022 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 2022 is: 1:37.75.

The ratio is calculated on the basis of the lowest FTE pay per 31 December 2022,
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 2022 year-end
process, the actual annual bonus figures for employees below the Executive Committee
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 2022 actual bonus outcomes.

Minimum share ownership
From the financial year 2020, our remuneration policy has set a minimum threshold of
shares to be held at any time by the Chief Executive Officer to the number of shares
equivalent to one year of the Chief Executive Officer’s annual base salary and by the other
members of the Executive Committee to the number of shares equivalent to six months’
of the relevant Executive Committee member’s annual base salary. Thresholds will be re-
calculated on an annual basis and need to be reached within four years. For our Chief
Executive Officer, Stoffels IMC BV (permanently represented by Dr. Paul Stoffels), we will
calculate and disclose the applicable threshold for the first time in our annual report for
financial year 2023.

Severance clauses and payments

Severance payments for departing members of the
Executive Committee
On 30 August 2021, Galapagos announced the planned retirement of its Chief Executive
Officer Onno van de Stolpe and after a transition period Stoffels IMC BV, permanently
represented by Dr. Paul Stoffels, took over as Chief Executive Officer effective 1 April 2022.
The retirement package of our former Chief Executive Officer, Onno van de Stolpe, has
been disclosed in the annual report for financial year 2021.

In 2022, Dr. Andre Hoekema retired from Galapagos per 31 December 2022 and as of
31 October 2022 he was no longer a member of the Executive Committee. He executed
an advisory role until 31 December 2022, for which he continued to receive his base
salary. He qualifies as a good leaver under the terms and conditions of the subscription
right plans given his retirement.

For the avoidance of doubt, Dr. Hoekema will not receive a grant under the 2023 RSU
Annual Long-Term Incentive Plan equivalent to his 2022 short-term cash bonus.

Effective 1 January 2023, Dr. Walid Abi-Saab is no longer a member of our Executive
Committee. He will execute a purely advisory role until 31 May 2023, for which he will
continue to receive a his 2022 base salary and retains entitlement to RSU pay-outs until
the aforementioned date.

For the avoidance of doubt, Dr. Walid Abi-Saab will not receive a grant under the 2023
RSU Annual Long-Term Incentive Plan equivalent to his 2022 short-term cash bonus. He
will qualify as a good leaver under the terms and conditions of the subscription right
plans, pursuant to an exception granted by the Board of Directors under the relevant
subscription right plans.

Claw-back right of Galapagos relating to variable
remuneration
As from financial year 2020, contractual provisions apply to each member of the
Executive Committee to ensure that Galapagos has the right to have each Executive
Committee member forfeit any unvested RSUs, deferred portions of previous cash
bonuses or unvested subscription rights (i) in the event of a restatement of the financial
statements that has a material negative effect on Galapagos or (ii) a material breach of
our Code of Conduct and Ethics.

During the financial year 2022 no claw-back events occurred.

The 2022 RSU plans and 2022 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. On the leaver date of Mr.
Onno van de Stolpe and Dr. Andre Hoekema, their outstanding RSUs under several RSU
plans became null and void, respectively, being 65,158 RSUs and 39,407 RSUs.

Deviations from the remuneration policy
Galapagos’ remuneration policy sets out that the Board of Directors 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 Remuneration
Committee, which will provide a substantiated recommendation to the Board of
Directors. No deviations are disclosed in this remuneration report.

Conflict of interests and related parties

We consider that Gilead became a related party of Galapagos NV in 2019 because of
(i) Gilead’s then 25.84% shareholding (25.38% on 31 December 2022) in Galapagos NV,
and (ii) the fact that Gilead is entitled to propose two candidates to be appointed to
our Board of Directors under the share subscription agreement dated 14 July 2019, as
amended.

On 4 March 2022, 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 responsibility for the MANTA study, a safety study
in men with moderately to severely active UC and CD to assess semen parameters
while taking filgotinib, and its long-term extension study, from Gilead to us. The (former)
Supervisory Board (currently Board of Directors) resolved and confirmed, as far as
needed, that the related party transaction approval mechanism as set forth in article
7:116 of the Belgian Companies Code did not have to be applied, since the value of the
aforementioned related party transaction is less than 1% of the Company’s consolidated
net equity (based on the consolidated financial statements of Galapagos NV for the
financial year ended on 31 December 2021) and since Galapagos NV is therefore able
to rely on the materiality exemption as set out in article 7:116, § 1, 2° of the Belgian
Companies Code. Furthermore, we entered into some mainly technical and non-
material amendments to the existing transactions with Gilead during 2022. A more
detailed explanation of some of our transactions with Gilead 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 member of the Board of Directors has a conflict of
interests within the meaning of article 7:96 of the Belgian Companies Code, such Board
member shall notify the Board of Directors in advance of the respective conflict, and will
act in accordance with the relevant rules as set out in the Belgian Companies Code (i.e.
article 7:96 of the Belgian Companies Code).

Pursuant to our Corporate Governance Charter, if a member of the Executive Committee
has a direct or indirect interest of a monetary nature that conflicts with the interests
of the Company in respect of a decision or an act falling within the scope of the
responsibilities of the Executive Committee, the Executive Committee shall refrain from
making any decision. The Executive Committee shall instead escalate the matter to the
Board of Directors. The Board of Directors shall decide whether or not to approve such
decision or act, and shall apply the conflict of interests procedure set out in article

145
Galapagos NV Annual Report 2022

CORPORATE GOVERNANCE

7:96 of the Belgian Companies Code. In the event a conflict of interests exists within
the Executive Committee that falls outside of the scope of article 7:96 of the Belgian
Companies Code, the existence of such conflict shall be reported by the relevant
Executive Committee member, its existence shall be included in the minutes (but shall
not be published) and the relevant Executive Committee member shall not vote on the
matter.

In addition, the Company's Corporate Governance Charter and Galapagos’ Related
transactions between
Person Transaction Policy contain certain procedures for
Galapagos NV (including its affiliated and associated companies within the meaning
of articles 1:20 and 1:21 of the Belgian Companies Code) and its Board or Executive
Committee members, major shareholders, or any of their immediate family members
and affiliates. Without prejudice to the procedure as set out in article 7:96 of the Belgian
Companies Code, these policies provide that all transactions between Galapagos NV
(including its affiliated and associated companies within the meaning of articles 1:20 and
1:21 of the Belgian Companies Code) and its Board or Executive Committee members,
need the approval of the Audit Committee and the Board of Directors, which approval
can only be provided for transactions at arm’s length. Moreover, conflicts of interests,
even if they are not a conflict of interests within the meaning of article 7:96 of the
Belgian Companies Code, are enacted in the Board of Directors' meeting minutes, and
the relevant Board member cannot participate in the deliberation or voting on the
concerned item on the agenda.

In 2022, the following conflict of interests between Galapagos NV and a director within
the meaning of article 7:96 of the Belgian Companies Code was noted:

In a meeting of the Board of Directors held on 21 June 2022, the following was
reported in accordance with article 7:96 of the Belgian Companies Code in
connection with the proposed amendment of the management agreement between
Galapagos NV and Stoffels IMC BV: the Chairman, being a party to the management
agreement (as CEO), declared having a conflict of interests concerning the proposed
amendment. The Chairmain subsequently left the meeting before the deliberation
and the vote concerning this point on the agenda took place. The Board considered
that said amendment is limited in scope and cost neutral for the Company: the
reimbursement by the Company of Stoffels IMC BV’s expenses for travel was reduced,
and it was clarified that Stoffels IMC BV will bear all costs related to commuting travel.
This was proposed to be compensated by an increase of its fixed fee with €50,000 on
a yearly basis. As such, the Board considered that said amendment is justified and
will have no material impact on the financial position of the Company.

Code of Business Conduct and Ethics

Since 2021, we have established a Code of Business Conduct and Ethics to ensure that
our members of the Board of Directors, Executive Committee members and employees
are making ethical and legal decisions when conducting Galapagos’ business and
performing their day-to-day duties. We expect our members of the Board of Directors,
members of the Executive Committee and employees to conduct business with integrity,
ethics and respect for human rights. We expect them to turn away from conflicts of
interests, corruption and fraud. To this end, we give trainings on this Code to our
employees, including our subsidiaries’ employees. So far, since the launch of our Code
of Business Conduct and Ethics, 97.1% of our employees has completed the training.

Our Code of Business Conduct and Ethics is available at our website (www.glpg.com).

At the beginning of 2023, we made some updates to our Code of Business Conduct and
Ethics to ensure that it continues to reflect who we are as an organization, including, but
not limited to, (a) an explicit applicability of our Code of Business Conduct and Ethics to
our suppliers and business partners, and (b) an overview of some of the work done in the
past year in the field of ESG.

One breach of our Code of Business Conduct and Ethics was reported to the Audit
Committee in 2022.

of Fidelta (our fee-for-service segment), we have reported this segment as discontinued
operations.

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.

Conflict in Ukraine
To date, we have experienced very limited impact of the armed conflict between Russia
and Ukraine. However, we keep on monitoring the impact of the situation.

2. Summary of significant transactions

GILEAD COLLABORATION AGREEMENT
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
Sareholders 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
2021 and 31 December 2022. On 31 December 2022 the value of the subsequent Warrant
B decreased to €0.7 million, driven by the decrease of our share price, and of the implied
volatility in 2022.

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

157
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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 Board of Directors of
Galapagos (Daniel O’Day and Linda Higgins).

In Q4 2020, Gilead decided not to pursue FDA approval of the RA indication for filgotinib
in the U.S. as the result of a 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 DIVERSITY clinical study, evaluating
filgotinib in CD, and its long-term extension study. The DIVERSITY clinical study was
transferred and as of 1 April 2022, we were 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.

FINANCIAL STATEMENTS

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.

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.

requirements. All activities have been as of 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 continued 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 were transferred 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 connection with the amendments to the existing arrangement for the
commercialization and development of filgotinib, Gilead paid us €160 million, which
is split between a €110 million payment received in 2021 and a €50 million payment
received in 2022 and is subject to certain adjustments for higher than budgeted
development costs. In 2022, Gilead made a one-time payment of $15 million to us in
consideration for assuming responsibility for the DIVERSITY clinical study. In addition, we

159
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

will no longer be eligible to receive any future milestone payments relating to filgotinib
in Europe. In 2022, we also received from Gilead $20 million of milestone payment for
the regulatory approval of filgotinib in UC in Japan. Other terms of the original license
agreement remain in effect, including the remaining $275 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).

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. Gilead’s ownership amounted to 25.38% at 31 December 2022.

BUSINESS COMBINATIONS
On 21 June 2022 we acquired, in an all-cash transaction, 100% of the shares and voting
interests of CellPoint. On the same date we acquired all of the outstanding capital and
voting interests of AboundBio.

We refer to note 12 Goodwill and impairment of goodwill and note 26 Business
combinations during the period, for more information.

3. Significant accounting policies
Our principal accounting policies are summarized below.

Basis of preparation and going concern assumption
The consolidated financial statements are prepared in accordance with the International
Financing Reporting Standards (IFRS), as adopted by the EU. The consolidated financial
statements provide a general overview of our activities and the results achieved. They
give a true and fair view of our financial position, our financial performance and cash
flows, on a going concern basis.

New standards and interpretations applicable for the annual
period beginning on 1 January 2021
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.

New standards and interpretations applicable for the annual
period beginning on 1 January 2022
New standards and interpretations applicable for the annual period beginning on
1 January 2022 did not have a material impact on our consolidated financial statements.

Standards and interpretations published, but not yet
applicable for the annual period beginning on 1 January
2022
A number of new standards are effective for annual periods beginning on or after
1 January 2023 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

Consolidated reporting
The consolidated financial statements comprise the financial statements of Galapagos
NV and entities controlled by Galapagos NV (subsidiaries). 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 intra-group transactions, balances, income and expenses are
eliminated when preparing the consolidated financial statements.

financial position, the acquiree’s identifiable assets,

Business combinations
Business combinations are accounted for using the acquisition method. In the statement
of
liabilities and contingent
liabilities are initially recognized at their fair value at the acquisition date. The results
of acquired operations are included in our consolidated income statement from the
date on which control is obtained. Any contingent consideration to be transferred by
us is recognized at fair value at the acquisition date. Subsequent changes to the fair
value of the contingent consideration, which is deemed to be an asset or liability, will
be recognized in profit or loss. The excess of the fair value of the total purchase
consideration transferred over the fair value of the acquired assets and assumed
liabilities is recognized as goodwill. The valuations in support of
fair value
determinations are based on information available at the acquisition date. Acquisition
related costs are expensed as incurred.

Contingent amounts payable or paid by us to former shareholders of acquired
companies, who continue to be employed by us, but which would be automatically
forfeited (or become repayable) upon termination of employment before a specific date,
are classified as remuneration for post-combination services on the appropriate line
in our consolidated income statement. These cash-settled contingent amounts are
recognized in accordance with IAS 19 and are recorded on the balance sheet on the
lines “other (non-) current assets” and “other non-current/trade and other liabilities”
depending on the timing of the payment by us.

Goodwill
Goodwill
is initially measured as the excess of the total purchase consideration
transferred and the fair value of
the acquired assets and assumed liabilities.
Subsequently, goodwill is stated at cost less impairment and tested for impairment at
least annually at the level of the cash generating unit to which it was allocated. Any
impairment costs are recorded in our consolidated income statement on the line “Other
operating income/expense”.

162
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

Intangible assets other than goodwill
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

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, rights, technology and in-process research and development

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 launched.
Amortization will
is approved for
commence when the underlying asset
commercialization and the asset will be amortized over its useful life.

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

163
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

option is capitalized as intangible asset and amortized over the expected duration of the
option.

Exclusivity contracts and technology acquired through business combinations are
valued independently as part of the fair value of the businesses acquired and are
amortized over their estimated useful lives. The estimated useful life is based on the
lower of the contract life or the economic useful life.

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.

(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.

164
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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.

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 extension options (or periods after termination options) in the lease
term if the lease is 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.

165
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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.
These inventories are initially recognized at cost, and subsequently at the lower of cost
and net realizable value. Cost comprises all costs of purchase, conversion costs and
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 2022.

(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.

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.

166
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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.

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

167
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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 to 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 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 liabilities are initially measured either at fair value or at their transaction price.
Subsequent to initial recognition, financial liabilities are measured at amortized cost.

Financial
consideration liabilities.

liabilities mainly comprise trade and other

liabilities and contingent

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 expenses related to
our research and development project costs.

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

Contingent consideration liabilities

Any contingent consideration to be transferred by us in relation to businesses acquired
are linked to milestone payments and are initially recognized at fair value as a financial
liability. They are adjusted for the probability of their likelihood of payment and are
appropriately discounted to reflect the impact of time.

Changes in the fair value of these contingent consideration liabilities in subsequent
periods are recognized in our consolidated income statement on the line “other
operating income/expense”. The effect of unwinding the discount over time is
recognized in other financial results.

(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.

168
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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 the primary economic environment in which the entity operates. The
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.

169
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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 the sales of Jyseleca® in Europe, which are reported as
“Product net sales” in our consolidated income statement.

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:

170
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

Collaboration revenues

(i) identify the contract

In our 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.

(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 (which is generally only when the milestone is
achieved). 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

171
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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 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) to
measure the progress of the satisfaction of the underlying performance obligation
(which is the applied method for the filgotinib 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 (which is the applied method for the
performance obligation related to our drug discovery platform).

172
Galapagos NV Annual Report 2022

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.

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

174
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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) Bonus plans

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

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

Share-based payments

(i) Equity-settled share-based payments

We grant equity-settled incentives to certain employees, members of the Executive
Committee 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.

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

Members of the Executive Committee 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.

175
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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 other than goodwill

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.

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.

(iii) Goodwill

As goodwill is considered to have an indefinite life, it is tested for impairment annually,
and whenever there is an indication that it may be impaired, by comparing its carrying
amount with its recoverable amount (i.e. the higher of value in use and fair value less
costs to sell). If the recoverable amount of the cash-generating unit is less than the
carrying amount of the unit, the impairment loss is allocated first to reduce the carrying
amount of any goodwill allocated to the unit and then to the other assets of the unit pro
rata on the basis of the carrying amount of each asset in the unit. Impairment losses on
goodwill are not reversed.

176
Galapagos NV Annual Report 2022

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 in 2021 our reportable segments were R&D and fee-for-
service business. Fidelta is reported as discontinued operations for the year ended 31
December 2021.

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.

On 4 January 2021 we sold of our fee-for-service business Fidelta.

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.

178
Galapagos NV Annual Report 2022

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 2022.

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 2022 amounted to
€174.4 million. Our total deferred income balance related to this filgotinib performance
obligation amounts to €456.4 million on 31 December 2022. 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
2022 of €15.4 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 2022 of €16.0 million and a corresponding decrease in current
and non-current deferred income.

Goodwill impairment

Determining whether goodwill is subject to impairment requires an estimate of the
recoverable amount of the cash-generating unit to which the goodwill has been
allocated. The calculation of this recoverable amount includes forecasts of future cash
flows of the cash-generating unit (highly dependent upon the probability of success
linked to the progress of our clinical programs) and an appropriate discount rate is
required to calculate present values, a process which involves estimates. These

179
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

estimates are constantly monitored, and an impairment test will be performed as soon
as there is an impairment indicator and at least annually. The carrying value of goodwill
at 31 December 2022 is €69.8 million.

Contingent consideration

The contingent consideration included in the consideration payable for the acquisition
of CellPoint was recorded at fair value at the date of acquisition. These fair values were
mainly based on our best estimate of probabilities of reaching the underlying milestones
and by applying an appropriate discount rate. The fair values are reviewed at each
reporting date and any changes are reflected in our consolidated income statement. We
refer to the specific note on contingent consideration for more details.

5. Segment information

Geographical information
We are currently operating as a single operating segment. Prior to the disposal of Fidelta
in 2021 we had two reportable segments: R&D and fee-for-service business.

In 2022 our operations were mainly located in Belgium, France, the Netherlands,
Germany, Italy, Spain, Switzerland and the United Kingdom. The revenues from our
collaboration partner Gilead represented 82% of our total net revenues in 2022
(97% in 2021).

In 2022 we reported €87.6 million of product net sales for Jyseleca® in Europe
(€14.8 million in 2021) of which €7.3 million realized in Belgium (€1.7 million in 2021).

Product net sales
We reported product net sales of Jyseleca® for the year ended 31 December 2022 of
€87.6 million, as compared to €14.8 million for the year ended 31 December 2021. Our
counterparties for the sales of Jyseleca® during 2022 were mainly hospitals and
wholesalers located across Europe. Jyseleca net sales have significantly grown driven by
volume uptake of existing business and by new launches in both indications in multiple
countries.

Net sales exclusively consisted of sales of Jyseleca® in Europe.

€230.4 million in 2022. For the year ended 31 December 2022 we also recognized in
revenue €10.7 million of royalties from Gilead on filgotinib.

Additionally, we recorded in 2022 milestone payments of €2.0 million triggered by the
initial sales of Jyseleca® in the Czech Republic and Portugal by our distribution and
commercialization partner Sobi.

(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, to €57.3 million on 31 December 2021 and to €58.7 million on 31 December 2022.

In 2022 we received $20.0 million (€18.2 million) of milestone payments for the regulatory
approval of filgotinib in UC in Japan and recognized €10.7 million of royalties from
Gilead.

A summary of our main contracts with customers and distribution/commercialization
partners is given below:

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

183
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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).

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.

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
the
delivered. Milestone payments are included in the transaction price of
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 2021 and 2022 we
reported respectively €3.8 million and €10.7 million of revenues from royalties from
Gilead.

184
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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.

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 2022.

Collaboration with Sobi
In October 2021, we signed an agreement with Sobi regarding the distribution of
Jyseleca®. Sobi will distribute the medicine in Central and Eastern Europe, Greece,
Portugal, and the Baltic countries.

Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

The variance in our R&D expenditure in 2022 compared to 2021 was principally due to
the following elements:

Depreciation and impairment costs in 2022 amounted to €54.5 million (€17.5 million
in 2021). This increase was primarily due to an impairment of €26.7 million of
previously capitalized upfront fees related to our collaboration with Molecure on
the dual chitinase inhibitor OATD-01 (GLPG4716) in fibrosis and impairments of
intangible assets related to other discontinued projects recorded in 2022 for an
amount of €8.9 million.

Personnel costs increased from €165.2 million in 2021 to €190.1 million in 2022
primarily explained by increases in restructuring costs and accelerated non-cash cost
recognition for subscription right plans related to good leavers.

Subcontracting costs decreased from €251.1 million in 2021 to €214.9 million in 2022
following the evolution of our programs.

The increase in R&D expenditure in 2022 was primarily explained by cost increases for
our filgotinib program and new investments in 2022 in CAR-T programs in oncology.
This was partly offset by cost decreases due to the winding down of the ziritaxestat (IPF)
program and reduced spend on our SIKi, TYK2 and other programs.

Major part of the increase in our sales and marketing expenses in 2022 is due to the
termination of our 50/50 filgotinib co-commercialization cost sharing agreement with
Gilead as from 1 January 2022 explaining €59.7 million of the variance. Personnel costs
increased by €12.8 million in 2022 compared to 2021, explained by an increase in salaries
and benefits following the growth of the commercial work force from 248 average FTEs in
2021 to 305 average FTEs in 2022 driven by the commercial launch of filgotinib in Europe.

Other operating expenses increased from €7.2 million in 2021 to €15.0 million in 2022
largely due to increased travel expenses.

External outsourcing costs decreased by €8.3 million primarily explained by lower costs
for marketing studies and materials.

The grant income in 2022 and 2021 were 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 also included a grant of
€5.4 million from the National Institute for Health and Disability Insurance (2022: nil).
This grant aimed to incentivize innovative Belgian biotech companies who are
performing research and development activities in order to identify new medicines.

R&D incentives income was primarily composed of:

Income from an innovation incentive system of the French government, which
represented €11.4 million for the year ended 31 December 2022 compared to
€12.4 million for the year ended 31 December 2021

Income from Belgian R&D incentives with regard to incurred R&D expenses, which
represented €17.3 million for the year ended 31 December 2022 compared to
€20.9 million for the year ended 31 December 2021

Other income increased from €1.5 million in 2021 to €6.4 million in 2022 mainly due to

During 2022 we changed the presentation of our financial results in our consolidated
income statement in order to isolate the net currency exchange differences and fair value
re-measurements. We retrospectively adjusted the 2021 comparative figures to reflect
this change. In our 2021 consolidated financial statements we reported total currency
exchange gains of €60.7 million and total currency exchange losses of €4.2 million for
the year ended 31 December 2021 on the "other financial income" and "other financial
expenses" line respectively. The (fair) value gains on current financial investments (€6.8
million for the year ended 31 December 2021) were also reported on the line "other
financial income" in our 2021 consolidated financial statements.

The net currency exchange gain in 2022 of €44.4 million primarily consisted of an
unrealized exchange gain of €41.3 million on cash and cash equivalents and current

190
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

investments at amortized cost held in U.S. dollars, as compared to an
financial
unrealized exchange gain in 2021 of €56.6 million on cash and cash equivalents and
current financial investments at amortized cost held in U.S. dollars. 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.

Fair value re-measurement of warrants refers to the fair value re-measurement of initial
warrant B. The fair value of the financial liability related to the initial warrant B of
€0.02 million on 31 December 2022 (€0.2 million on 31 December 2021) is presented as
part of trade and other liabilities in our consolidated statement of financial position and
will be re-measured at each reporting period. We refer to note 2 for more information.

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. This resulted in a
net book value of zero of the financial assets held at fair value through profit or loss on
31 December 2021. The fair value gain on the current financial investments in 2022 and
2021 reflected the positive exchange differences booked on the money market funds,
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
2022 and on 31 December 2021. These re-measurement losses were mainly the result of
the negative returns on the EUR denominated money market funds.

Interest income was related to interests on term deposits, notice accounts and current
financial investments. Net interest income increased due to increasing interest rates.

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 2022 also
included €7.7 million of costs (€9.3 million for the year ended 31 December 2021) 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. They also comprise the discounting effect of other non-current liabilities as
deferred consideration and milestones payables related to the acquisition of
subsidiaries.

The goodwill resulting from both the acquisition of CellPoint (€62.4 million) and
AboundBio (€7.4 million) was allocated to the same cash-generating unit (CGU),
“oncology”. The intangible assets acquired as a result of both business combinations
were also allocated to this cash-generating unit, together with some other (in)tangible
assets related to the “oncology” cash-generating unit. The valuation method of the
recoverable amount of this cash-generating unit is based on the fair value less costs of
disposal.

The valuation technique that was applied to determine the fair value less costs of
disposal of the cash-generating unit is a discounted cash flow method (“DCF”) with
projected cash flows that cover a period of 13 years. The period considered exceeds
five years because the main sales are expected for the period beyond 2027. The key
assumptions used in this valuation (level 3 in the fair value hierarchy) of the recoverable
amount of the underlying cash-generating unit were:

Probability of success of our clinical programs that is based on benchmarks in
combination with management estimate

Terminal growth rate of –50% reflecting the anticipated sales evolution beyond 2035

Discount rate of 12.5%

Future revenue and investment assumptions are based on management estimate of
the overall cell therapy market

No impairment was identified per 31 December 2022.

Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

New additions in 2022 primarily related to the capitalization of an in-licensing fee for
an amount of €7.5 million and of a milestone payment of $1.0 million, and software
acquisitions for a total amount of €1.1 million.

In 2022 we recorded an impairment of €26.7 million on previously capitalized upfront
fees related to our collaboration with Molecure on the dual chitinase inhibitor OATD-01
(GLPG4716) in fibrosis, and impairments of €8.9 million on intangible assets related to
other discontinued projects.

On 31 December 2022, our balance sheet did not hold any internally generated assets
capitalized as intangible asset.

The other tangible assets primarily consist of assets under construction, which are not
yet available for use and therefore not yet depreciated as per 31 December 2022.

During 2022, the construction of our new building in Oegstgeest (the Netherlands) was
completed which explains the reclassification from “other tangible assets” to “land,
building and building improvements” for €64.3 million.

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).

The increase in R&D incentives receivables is explained by additional R&D incentives
reported in 2022 for €28.7 million (€11.4 million related to French incentives and
€17.3 million related to Belgian incentives), by the release of discounting profit of
€0.1 million, partly offset by the setup of tax provisions in France and Belgium for
respectively €0.2 million and €0.2 million and decreased by the payments received in
2022 related to French and Belgian incentives amounting to respectively €10.2 million
and €16.1 million. The R&D tax 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 2022.

FINANCIAL STATEMENTS

Trade and other receivables decreased primarily due to the outstanding receivables
as at 31 December 2021 of €50.0 million on Gilead related to the additional payments
in the scope of the renegotiated agreement of December 2020 for filgotinib, and of
€12.6 million ($15 million) on Gilead following the agreement for the take-over by us of
the DIVERSITY clinical trial, which were both paid in 2022. 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 interest income and deferred charges.

On 31 December 2022, we did not have any provision for expected credit losses.

Term deposits refer to non-cancellable term deposits with a maturity exceeding three
months from the acquisition date. Our portfolio of treasury bills contains only AAA rated
paper, issued by Germany. Our money market funds portfolio consists of AAA short-term
money market funds with a diversified and highly rated underlying portfolio managed
by established fund management companies with a proven track record leading to an
insignificant risk of changes in value. The funds have an important daily liquidity and can
be easily converted to cash.

On 31 December 2022, our current financial investments included $809.6 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 net exchange differences
(exchange difference on term deposits) and in the fair value result of current financial
investments (exchange difference on money market funds) in our consolidated income
statement.

We refer to note 34 for more information on our current financial investments and to
note 9 for more details about the fair value re-remeasurements and currency exchange
gains or losses recognized in our income statement.

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 2022 comprised
€50.0 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 2022, our cash and cash equivalents included $97.3 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 9 for more details about the currency exchange gains
or losses recognized in our consolidated income statement.

The Board of Directors 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 such
renewal in the Annexes to the Belgian State Gazette, which occurred on 13 November
2019. This general authorization will expire on 12 November 2024.

A specific authorization for capital increases of more than 20% and up to 33% of the
share capital at the time of the convening of 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 such renewal in the Annexes to the Belgian State Gazette,
which occurred on 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 Board of Directors that all independent members of the Board of Directors
(within the meaning of article 7:87 of the Belgian Companies Code and 2020 Code)
approve. The Board of Directors 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 expired on
30 May 2022.

As of 31 December 2022, an amount of €24,889,284.17 still remained available under the
general part of the authorized capital.

The consolidated tax losses, innovation income deduction, dividend received deduction
and investment deduction carried forward and the deductible temporary differences
on 31 December 2022 amounted in total to €1,882.5 million (2021: €1,653.7 million),
€2.7 million were related to tax losses with expiry date between 2028 and 2034.

Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

The available tax losses carried forward that can be offset against possible future taxable
profits amounted to €883.6 million on 31 December 2022 (€635.6 million on 31
December 2021) and can be carried forward for an indefinite period except for an
amount of €2.7 million in the United States with expiry date between 2028 and 2034. On
31 December 2022, the available tax losses carried forward in Galapagos NV (Belgium)
amounted to €769.9 million (2021: €556.9 million). In addition to the latter, Galapagos
NV (Belgium) also benefits from the Belgian innovation income deduction regime which
led to report, on 31 December 2022, a carried forward tax deduction amounting to
€346.2 million (2021: €301.3 million) that can also be offset against possible future
taxable results. In addition, Galapagos NV (Belgium) also has available investment
deduction carried forward of €1 million (2021: €1 million) and dividend received
deduction carried forward of €18.7 million (2021: €8.2 million) that can be offset against
possible future taxable profits. There is no limit in time for the innovation income
deduction, 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 2022, except for one subsidiary operating on a cost
plus basis,
for which a deferred tax asset was recognized for €1.1 million (2021:
€4.0 million, for two subsidiaries).

Net deferred tax liabilities were initially calculated based on the fair value of the
intangible assets identified from the acquisition of CellPoint and AboundBio, adjusted
by considering the related recognizable deferred tax assets. We refer to note 26 for more
information on the purchase price allocation of the business combinations.

The increase in both trade and other liabilities and other non-current liabilities can
be largely explained by contingent and deferred considerations payable related to the
acquisition of CellPoint, recorded in 2022.

The contingent consideration arrangement relating to the acquisition of CellPoint
requires us to pay the former owners of CellPoint additional considerations up to €100.0
million. This amount is due when certain sequential development (€20.0 million),
regulatory (€30.0 million) and sales-based (€50.0 million) milestones would be achieved.
Total fair value at acquisition date of these milestones amounted to €20.2 million.

The fair value measurement is based on significant inputs that are not observable in
the market, which are classified as Level 3 inputs. Key assumptions in the valuation
at 31 December 2022 include a discount rate of 12.5%, an appropriate probability of
success of reaching these milestones and expected timing of these milestones. A change
in probabilities of success of each milestone by 5 percentage points would result in a
change of €3.1 million in the total contingent consideration liability on 31 December
2022.

As per 31 December 2022 no change was made to the key assumptions. The only impact
that was recognized compared to the date of acquisition is the discounting effect. This is
recognized on the line “other financial expenses”.

Of the total contingent consideration liability at 31 December 2022, €8.5 million is
expected to be paid within one year and therefore presented on the line “trade and other
liabilities” in our statement of financial position. The long-term portion, amounting to
€13.6 million, is presented on the line “other non-current liabilities”.

26. Business combinations during the period
On 21 June 2022 we acquired, in an all-cash transaction, 100% of the shares and voting
interests of CellPoint for a total agreed payment at completion of €125 million, including
consideration for other liabilities associated with the transaction amounting to
€10.3 million. Additional contingent consideration up to €100.0 million is due when
certain milestones would be achieved.

On the same date we acquired all of the outstanding capital of AboundBio, for a total
agreed price of $14 million, including consideration for other liabilities associated with
the transaction.

FINANCIAL STATEMENTS

The main reason for these acquisitions is to position ourselves in the next-generation
cancer therapy market and to significantly broaden our portfolio and capabilities. As
a result of these acquisitions, we gain access to an innovative, scalable, decentralized
and automated point-of-care cell therapy supply model as well as a next-generation fully
human antibody-based therapeutics platform. Combined and supported by us as a fully
integrated biopharma, they have the potential to disrupt the CAR-T treatment paradigm.
The goal is to expand the current market for CAR-T therapies and have an important
impact on patients in need of additional and improved treatment options.

At the time of approval for issuance of these consolidated financial statements, our initial
accounting for the business combinations, including the purchase price allocation, has
been completed.

Details of the fair value of identifiable assets and liabilities acquired in both transactions,
the purchase consideration, the goodwill at the acquisition date and the net cash
outflow arising on acquisition are as follows:

As part of the acquisitions, we identified the following acquired intangible assets:

IPR&D: in-process research and development related to two CD19 CAR-T product
candidates in Phase 1/2a clinical studies. The fair value at acquisition date
(€28.2 million) was based on the relief from royalty method.

Exclusive rights: through the acquisition of CellPoint we acquired on the one hand
a collaboration agreement between CellPoint and Lonza providing the exclusive
right to use the automated Lonza Cocoon® Platform in the development and
commercialization of CAR-T cell products, and secondly, a collaboration agreement
between CellPoint and Hypertrust providing exclusivity to use the jointly developed
XCellit software for workflow management and monitoring for the manufacturing of
the CAR-T cells using the Lonza Cocoon® Platform. The fair values at acquisition date
amounted to €89.7 million and €2.6 million respectively. A with and without method
was retained to value the exclusivity with Lonza and the XCellit software was valued
based on the applicable royalty rate in the contract.

Technology: through the acquisition of AboundBio, we acquired a fully human
antibody-based therapeutics platform which was valued at €4.1 million at the time of
acquisition.

We assessed that the carrying value of all other acquired assets and assumed liabilities
approximate their fair value at acquisition date.

The goodwill arising from both transactions totaling €69.8 million is attributable to buyer
specific synergies, the value of the assembled workforce and the accounting for net deferred

212
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

tax liabilities for a total amount of €23.3 million, consisting of deferred tax liabilities on the
acquired intangible assets of €32.3 million less recognized deferred tax assets of €9.0 million.

The acquisition costs related to both transactions were considered not to be material
and were recognized in our consolidated income statement on the line "general &
administrative expenses”.

Since the acquisition date, there has not been a material contribution by both acquired
companies to total revenues and total result, nor were there major expenses prior to the
acquisitions, except for expenses directly linked to the acquisitions.

27. Discontinued operations
On 23 November 2020 we signed a share purchase agreement with Selvita S.A. in relation
to the disposal of Fidelta d.o.o. (our previous fee-for-service segment).

The transaction was completed on 4 January 2021 for a total consideration of
€37.1 million. Fidelta will continue performing drug discovery services for us for the
next three years for which we have purchase commitments for an aggregate amount of
€12.2 million on 31 December 2022.

Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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 2022 in relation to subscription right plans
amounted to €88,506 thousand (2021: €70,726 thousand).

The following table provides an overview of the outstanding subscription rights per
category of subscription right holders on 31 December 2022 and 31 December 2021:

The outstanding subscription rights at the end of the accounting period have a weighted

1,913 days (2021: 1,955 days).

Restricted stock units (RSUs)
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, in accordance with the terms and conditions of the relevant RSU
program.

We currently have the following RSU programs:

Plan 2020.I, Plan 2021.I and Plan 2022.I: these plans are intended to provide a long-
term incentive to certain of our employees and Executive Committee members and, as
of 2020, replace the deferred portion of the bonus under the former Senior Management
Bonus Scheme;

Plan 2019.II, Plan 2020.II, Plan 2021.II, Plan 2021.IV and Plan 2022.II: these plans are
designed with the aim to retain a specific group of our key employees and Executive
Committee members whose retention is considered so important for our future
performance that an additional incentive is desirable. The beneficiaries are nominated
by the Remuneration committee and the Board of Directors approves this list of
beneficiaries. The four-year vesting period is designed to be aligned with long-term
shareholder interests;

221
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

Plan 2019.I: this plan was granted at the discretion of the Board of Directors;

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 and Plan 2022.III: these plans are 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 RSU 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 Executive Committee, 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.

The table below sets forth a summary of RSUs outstanding at 31 December 2022, per

share on Euronext Brussels over the 30-calendar day period preceding the reporting
period and they are re-measured at each reporting date. We recognize the corresponding
expense and liability over the vesting period. The total liability relating to outstanding
RSUs on 31 December 2022 amounted to €12.9 million (2021: €11.3 million).

Relationship and transactions with entities with control of,
or significant influence over, Galapagos

Gilead

Gilead exercises 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 25.49% at
31 December 2021 and to 25.38% at 31 December 2022, due to seven capital increases
resulting from the exercise of subscription rights under employee subscription right
plans in the course of 2021 (four capital increases) and 2022 (three capital increases).

223
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

The presumption of significant influence is also confirmed by Gilead's right, for as long
as it holds more than 20% of Galapagos’ share capital, to appoint two investor Board
designees to Galapagos’ Board of Directors, out of a total of nine.

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 mainly contained €50 million of
receivables related to the in 2020 modified collaboration for filgotinib, €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 and €23.8 million of profit and
cost sharing receivables relating to our collaboration for filgotinib. All these amounts
were paid during 2022. The outstanding receivables on 31 December 2022 mainly relate
to development cost sharing receivables relating to our collaboration for filgotinib
(€5.0 million) and €2.6 million of receivables relating to royalties.

During 2022 we recognized in revenue €230.4 million (€230.6 million for the year ended
31 December 2021) relating to the performance obligation for the drug discovery
platform and a total of €174.4 million (€235.7 million for
the year ended
31 December 2021) 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.

Additionally, we recognized in 2022 royalty income for an amount of €10.7 million in
relation to the commercialization of
the year ended
31 December 2021).

filgotinib (€3.8 million for

the year ended
Furthermore, we recognized €0.4 million (€18.1 million for
31 December 2021) 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). A net amount of €2.4 million (€81.3 million for
the year ended
31 December 2021) relating to cross charges from and to Gilead relating to filgotinib was
recognized as expense on the line research and development expenditure.

Finally, we recognized in 2022 €0.03 million as a deduction of sales and marketing
expenses and €0.03 million as a research and development expenditure (compared to a
deduction of €59.7 million of sales & marketing expenses and a deduction of €7.0 million
of research & development expenditure for the year ended 31 December 2021) 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.

224
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

This profit/(cost) share mechanism for sales and marketing expenses came to an end
beginning of 2022, which explains the variance compared to 2021.

We purchased raw materials, semi-finished products and finished products of Jyseleca®
from Gilead for an amount of €13.5 million for the year ended 31 December 2022
(€24.9 million for the year ended 31 December 2021).

As at 31 December 2022 we have two outstanding performance obligations under IFRS
15 towards Gilead, which are 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 €1.5 billion for the drug discovery platform
(including the warrant issuance liability relating to subsequent warrant B) and
€456 million for the performance obligation relating to filgotinib.

A detailed explanation of our transactions with Gilead in 2022 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.

34. Financial risk management

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 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.

Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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 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 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
investments and cash and cash equivalents amounted to
financial
€4,094.1 million on 31 December 2022. 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 product sales,
royalties, 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.

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.

230
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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 is no history of material credit losses and the high-quality nature of our customers.

Aging balance of receivables that are due, but that are still considered collectable:

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.

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 €40.9 million (2021: €47.0 million); a 100
basis points decrease in interest rates would have decreased profit or loss, and equity,
by approximately €40.9 million (2021: €47.0 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
functional currency is euro, but we receive payments from our main
principal
collaboration partner Gilead in U.S. dollars and acquire some consumables and
materials in U.S. dollars, Swiss francs, and GB pounds.

231
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

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 collaboration 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:

Net book value (thousands of €)

Increase in Euros - U.S. Dollars

Increase in Euros - GB Pounds

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
investments, cash and cash
equivalents, 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.

financial

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.

35. Statutory auditor’s remuneration
The statutory auditor’s fees for carrying out its mandate at group level amounted to
€ 1,127.1 thousand in 2022 (2021: €860.3 thousand). Audit-related fees, which generally
the auditor provides, amounted to €26.9 thousand in 2022 (2021: €101.1 thousand).
Other fees related to non-audit services executed by the statutory auditor amounted

232
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

to €0 in 2022 (2021: €0). Other fees related to non-audit services executed by persons
related to the statutory auditor amounted to €429.5 thousand in 2022 and related to
advisory services in relation to IT and quality management (2021: €587.7 thousand). The
Audit Committee and the Board of Directors 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 and Associations
Code.

36. Events after balance sheet date
On 8 February 2023, we announced topline results from Phase 3 DIVERSITY trial of
filgotinib in CD and our decision not to submit a Marketing Authorization Application in
Europe based on these topline results. By consequence, we expect a decrease to the
total estimated remaining costs for us to complete the filgotinib development, resulting
in a positive catch up of revenues in 2023. At the time of the issuance of this annual
report, our re-assessment of the estimated remaining costs is still ongoing. If our best
estimate of the remaining cost to complete the filgotinib performance obligation would
be decreased by 15% to 25%, this would result in an increase in revenue recognition in
2023 of €50 million to €86 million, and a corresponding decrease in current and non-
current deferred income.

On 20 March 2023, 61,560 subscription rights were exercised (with an average exercise
price of €28.75 per subscription right). This resulted in a share capital increase (including
issuance premium) of €1,769,850, and the issuance of 61,560 new ordinary shares as per
20 March 2023. The closing price of our share on Euronext Brussels and Amsterdam on
20 March 2023 was €35.47.

Our consolidated financial statements were approved by the Board of Directors, and
authorized for publication on 21 March 2023. They were signed on behalf of the Board of

Galapagos NV’s operating income decreased by €130.7 million in 2022,
€916.0 million in 2021 to €785.3 million in 2022. This decrease was due to a lower
turnover of €84.9 million, primarily due to decreased revenue recognition of upfront
payments, because of the lower increase in percentage of completion, as well as lower
revenue recognition of milestone payments. There was also a decrease due to internally
generated intangible assets – being capitalized R&D expenses – which contributed by
€43.2 million less to our operating income than previous year. Other operating income
decreased with €5.7 million and amounted to €12.8 million for the year ended
31 December 2022, including €1.8 million of grants recognized for R&D projects and
€8.5 million recuperation of withholding taxes for scientists.

The operating costs of 2022 amounted to €1,016.9 million compared to €1,107.7 million
in 2021.

Material purchases increased from €13.1 million in 2021 to €19.9 million in 2022.

235
Galapagos NV Annual Report 2022

FINANCIAL STATEMENTS

Services and other goods decreased substantially to €420.8 million compared to
€500.0 million in 2021, primarily due to decreased internal and external subcontracting
for our preclinical studies and clinical trials.

Personnel costs in 2022 increased to €77.8 million compared to €70.4 million in 2021,
mainly due increased severance payments. The number of employees at Galapagos NV
at the end of 2022 amounted to 442 as compared to 460 at the end of 2021, excluding
insourced personnel. The average number of FTE in 2022 decreased to 433, compared to
487 in 2021.

Depreciation decreased to €357.4 million in 2022, compared to €401.8 million in 2021,
and related primarily to amortization of capitalized R&D expenses. Galapagos NV
capitalizes its incurred R&D expenses and fully amortizes them in the same year.

Other operating charges decreased from €120.7 million in 2021 to €102.1 million in 2022
caused by a reduction in transferpricing management fees. Non-recurring operating
costs consisted of impairments of intangible fixed assets related to discontinued
projects.

Galapagos NV’s 2022 financial
income increased to €135.6 million compared to
€85.8 million in 2021, financial costs increased as well to €61.0 million compared to
€28.1 million in 2021. The net exchange gain decreased from €74.0 million in 2021 to
€54.9 million in 2022 and consisted mainly of non-realized currency exchange gains on
U.S. dollar, while the net interest income in 2022 amounted to €10.8 million as compared
to a net interest cost of €11.4 million in 2021. Financial income also included dividend
income of €10.5 million. 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 2022 of €19.1 million as compared to €20.2 million tax income in
2021, related to tax incentives for investments in intangible fixed assets.

Investments in fixed assets in 2022 amounted to €17.0 million, excluding the internally
generated assets. They consisted mainly of investments in intangible assets, being a
license and milestone payment and software, as well of costs for building improvements,
new laboratory and IT equipment.

Non-current and current other receivables amounted to respectively €87.8 million and
€82.4 million and included the receivable for tax incentives amounting to respectively
€87.8 million and €14.2 million in 2022, compared to other receivables for tax incentives
of €92.5 million and €6.6 million in 2021.

Galapagos NV’s cash position at the end of 2022 amounted to €4,091.1 million.

Report of the statutory auditor

Statutory auditor’s report to the shareholders’
meeting of Galapagos NV for the year ended
31 December 2022 – 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.

in accordance with the proposal of

We were appointed in our capacity as statutory auditor by the shareholders’ meeting
of 28 April 2020,
the board of directors
(“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 17 consecutive periods. We are the statutory auditor of Galapagos NV for
23 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 2022, 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 4 734 351 (000) EUR
and the consolidated statement of income and comprehensive income/loss shows a loss
for the year then ended of 217 991 (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 2022 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.

238
Galapagos NV Annual Report 2022

REPORT OF THE STATUTORY AUDITOR

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
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 board of directors 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 filgotinib performance
obligation under the license and collaboration
agreement with Gilead – 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 174,4 million EUR in 2022 from upfront
payments and milestone payments related to the filgotinib performance obligation
under the license and collaboration agreement with Gilead (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. 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

239
Galapagos NV Annual Report 2022

REPORT OF THE STATUTORY AUDITOR

consideration for our conclusion that procedures relating to the determination of the
estimated costs to complete the performance obligation,
impacting the revenue
recognition for 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 audit procedures related to the determination of the estimated costs impacting
the percentage of completion used for revenue recognition related to the filgotinib
performance obligation under the license and collaboration agreement with Gilead
included the following, among others:

We evaluated and tested 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.

We tested, on a sample basis, the accuracy and completeness of actual costs
incurred to date.

Our procedures on the reasonableness of the assumptions also included evaluating
management’s ability to reasonably estimate costs to complete the performance
obligation. Specifically, we:

Evaluated the appropriateness of changes made during the period to
management’s estimates of total costs to complete.

Performed a comparison of management’s prior period cost estimates to actual
costs incurred and approved.

Evaluated the period over which management is expecting the company to
complete its performance obligation.

Compared certain costs to third-party supporting evidence.

Considered the impact of any subsequent events on management’s
assumptions.

Accounting for Business Combinations – Cellpoint
B.V. – Refer to notes 3, 4, 12, 13, 24 and 26 to the
consolidated financial statements

Key Audit Matter Description
The company entered into an agreement to acquire CellPoint B.V. (“Cellpoint”) in June
2022, where the company acquired 100 percent of the outstanding shares and voting
interests in an all-cash transaction.

We identified the valuation of acquired in-process research and development (“IPR&D”)
and the valuation of the collaboration agreement for the exclusive right to use the Lonza
Cocoon® manufacturing platform, in addition to the contingent consideration liability
recognized in connection with the acquisition of CellPoint, as a key audit matter because

240
Galapagos NV Annual Report 2022

REPORT OF THE STATUTORY AUDITOR

of the judgments necessary for management to estimate the acquisition date fair value
of such balances.

The significant assumptions used to estimate the fair value of the acquired IPR&D,
collaboration agreement for the exclusive right to use the Lonza Cocoon® manufacturing
platform, and contingent consideration included discount rates, as well as certain other
business-related assumptions that form the basis of
forecasted financial results,
including probability of success factors and revenue forecasts. Given the complexity
of these assumptions this matter required a high degree of auditor judgment, and
increased extent of effort
including involvement of valuation specialists, when
performing audit procedures and evaluating the results of those procedures.

How the Key Audit Matter Was Addressed in the Audit
Our audit procedures related to the company’s accounting for the IPR&D, collaboration
agreement for the exclusive right to use the Lonza Cocoon® manufacturing platform
and the contingent consideration liability recognized in connection with the CellPoint
acquisition, included the following, among others:

We tested the effectiveness of the company’s controls associated with accounting for

Responsibilities of the board of directors for the preparation
of the consolidated financial statements
The board of directors 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 board of
directors 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 board of directors 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 board of directors either intends to liquidate the group or to cease
operations, or has no other realistic alternative but to do so.

REPORT OF THE STATUTORY AUDITOR

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 board
of directors in the way that the company’s business has been conducted or will be
conducted.

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 board of directors;

conclude on the appropriateness of the use of the going concern basis of accounting
by the board of directors 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;

242
Galapagos NV Annual Report 2022

REPORT OF THE STATUTORY AUDITOR

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 board of directors
The board of directors is responsible for the preparation and the content of the directors’
report on the consolidated financial statements, the statement of non-financial

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.

Single European Electronic Format (ESEF)
In accordance with the draft standard on the audit of the compliance of the financial
statements with the Single European Electronic Format (“ESEF”), we have also
performed the audit of the compliance of the ESEF format and of the tagging with the
technical regulatory standards as defined by the European Delegated Regulation No.
2019/815 of 17 December 2018 (“Delegated Regulation”).

The board of directors is responsible for the preparation, in accordance with the ESEF
requirements, of the consolidated financial statements in the form of an electronic file in
ESEF format (“digital consolidated financial statements”) included in the annual financial
report.

Small bowel CD (SBCD)
CD causes chronic inflammation and erosion of the intestines. It can affect different
regions of gastrointestinal tract including the stomach and small and large intestines.
While isolated SBCD is an uncommon presentation of CD, involvement of some portion
of the small bowel, particularly the ileum, is common

Small cell lymphocyte leukemia (SLL)
Small cell lymphocyte leukemia is a type of B-cell non-Hodgkin lymphoma, where the
SLL cancer is located in lymp nodes and/or the spleen

Statin
Statins are a class of lipid-lowering medications that reduce illness and mortality in those

(1) We disclose the tables in accordance with Annex II of Article 8 Climate Delegated Act and Article 2 of the Complementary Climate Delegated Act, although Galapagos concluded that

our core economic activities qualify as taxonomy-non-eligible activities (concurrently resulting in the absence of any taxonomy-eligible activities) and nil alignment with the
environmental objectives listed under the EU Taxonomy Regulation; hence we consider the informational value of this tables minimal. In addition, Galapagos does not perform any
fossil gas and nuclear energy related activities, as covered by the Complementary Climate Delegated Act.
