Webcast presentation tomorrow, 24 February 2023, at 14.00 CET / 8 AM ET, www.glpg.com

Mechelen, Belgium; 23 February 2023, 22.01 CET; regulated information – Galapagos NV ((Euronext &, NASDAQ:GLPG) reports 2022 results, supported by strong adoption of Jyseleca^® across Europe, and provides outlook for 2023.

Commenting on the full year results 2022, Dr. Paul Stoffels, CEO and Chairman of the Board of Directors of Galapagos said: "As I reflect on my first year as the new CEO and Chairman, we can be proud of what we have achieved in a very short time to reset our organization and embrace a new R&D strategy for a sustainable future. 2022 was a year of transformation and change.

Adding oncology as a new strategic therapeutic area, and CAR-T and biologicals as novel drug modalities, were key steps in our transformation. 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 a research engine for novel, differentiated CAR-T constructs, that together have the potential to deliver life-saving medicines to more patients, faster and more efficiently.

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, most recently including CAR-T, we have a differentiated portfolio of preclinical through to commercial assets."

Bart Filius, President, COO and CFO of Galapagos, added: "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 RA and UC across Europe. Based on the topline results from the Phase 3 DIVERSITY study of filgotinib in Crohn's disease, Galapagos decided not to submit a Marketing Authorization Application in Europe in this indication. On the other hand, following the positive opinion from the Committee for Medicinal Products for Human Use on the Type II variation application based on the safety data on semen parameters from the MANTA and MANTA-RAy studies, the European label for RA and UC has been updated, potentially broadening access for European patients who may benefit from this treatment. For 2023, we anticipate net Jyseleca^® sales in a range between €140 and €160 million. For the longer term, we believe Jyseleca^® can reach €400 million peak sales in RA, UC and axial spondyloarthritis.

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 external innovation to accelerate our R&D portfolio while progressing our internal programs. As part of our company transformation, we have meaningfully reduced our cost base. We anticipate our full year 2023 operating cash burn to decline to a range of €380 to €420 million."

Details of the financial results

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.

On 8 February 2023 we announced topline results from the Phase 3 DIVERSITY trial of filgotinib in Crohn's disease and, based on these topline data, decided not to submit a Marketing Authorization Application in Europe. While this recent event will not have an impact on our financial statements for the year ended 31 December 2022, we will provide further information in our 2022 annual report on the potential revenue recognition impact on our financial statements for the year ended 31 December 2023.

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 inital sales of Jyseleca^® in 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 primarily 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 G&A and S&M 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 €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 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 position

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, offset by (ii) €6.9 million positive changes in (fair) value of current financial investments and €44.5 million of mainly positive exchange rate differences, (iii) €6.7 million of cash proceeds from capital and share premium increase from exercise of subscription rights in 2022, and (iv) €153.4 million cash out from the acquisitions of CellPoint and AboundBio, net of cash acquired.

Acquisition of CellPoint and AboundBio

We have completed the initial accounting of the acquisitions of Cellpoint and AboundBio, including the purchase price allocations. Disclosures on the business combinations will be included in our full year 2022 annual report.

Outlook 2023

Immunology franchise

This year, we expect additional reimbursement decisions for Jyseleca^® in UC in Europe, and we anticipate that Sobi will further progress with reimbursement discussions in RA and UC in Eastern and Central Europe, Greece, and the Baltic countries. We also expect the final decision from the European Commission following CHMP's adoption of the recommendation of the PRAC to harmonize the EU labels of all approved JAK inhibitors. We plan to start a Phase 3 study in axial spondyloarthritis, and anticipate announcing the initial results from the FILOSOPHY Real-World Evidence Phase 4 study in RA.

We aim to recruit the first patients in the Phase 2 programs with our TYK2 inhibitor product candidate, GLPG3667, in DM in the first quarter of 2023, followed by the start of a study in SLE later this year.

To accelerate time-to-patients, we are diversifying our drug modality capabilities in immunology and recently announced that we aim to start clinical development with the CD19 CAR-T candidate, GLPG5101, in refractory systemic lupus erythematosus (rSLE).

Oncology portfolio

Patient recruitment in the European sites of the ATALANTA-1 Phase 1/2 study with CD19 CAR-T candidate, GLPG5101, in rrNHL as well as in the EUPLAGIA-1 study with CD19 CAR-T candidate GLPG5201 in rrCLL/SLL is progressing. We aim to provide Phase 1 topline results from both studies around mid-2023 and aim to include US patients in 2023.

We aim to expand the CAR-T portfolio with a BCMA CAR-T product candidate, GLPG5301, in refractory/relapsed multiple myeloma (rrMM) and aim to start enrolling patients in the PAPILIO-1 Phase 1/2 study in Europe in the second quarter of 2023.

Financial guidance

For the full year 2023, we anticipate further reduction of our cash burn and anticipate landing between €380 and €420 million (compared to €514 million for the full year 2022), including the acceleration in oncology. We also anticipate between €140 and €160 million net sales of Jyseleca^® for the full year 2023.

Taking into account multiple factors, we have revised our estimates of the peak sales potential for Jyseleca^® in RA, UC and axial spondyloarthritis and expect this to reach €400 million by the end of the decade.

ⁱⁱ The operational cash burn (or operational cash flow if this liquidity measure is positive) is equal to the increase or decrease in our cash and cash equivalents (excluding the effect of exchange rate differences on cash and cash equivalents), minus:

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

• the net proceeds or cash used, if any, related to the acquisitions or disposals of businesses; the movement in restricted cash and movement in current financial investments, if any, the cash advances and loans given to third parties, if any, included in the net cash flows 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 flows generated from/used in (-) operating activities.

This alternative liquidity measure is in our view an important metric for a biotech company in the development stage. The operational cash burn for the year 2022 amounted to €513.8 million and can be reconciled to our cash flow statement by considering the decrease in cash and cash equivalents of €1,747.5 million, adjusted by (i) the cash proceeds from capital and share premium increase from the exercise of subscription rights by employees for €6.7 million, (ii) the net purchase of current financial investments amounting to €1,087.0 million, and (iii) the cash out from acquisition of subsidiaries, net of cash acquired, of €153.4 million
