Mechelen, Belgium; 24 February 2022, 22.01 CET; regulated information – Galapagos NV ((Euronext &, NASDAQ:GLPG) presents financial results 2021, reviews key events for the company, and provides outlook for 2022.

"2021 was a year of reflection, resulting in refocused R&D activities and resized spend, as well as commercial roll-out, with a major effort to launch Jyseleca throughout Europe," said Onno van de Stolpe, CEO of Galapagos. "We made excellent progress with Jyseleca and successfully completed the process of becoming Marketing Authorization Holder (MAH) in Europe for our first medicine. Improving patients' lives is at the core of what we do, and completing our transition to a fully integrated, independent European biopharma is a major achievement to make that mission a reality for patients suffering from chronic debilitating conditions.

We received approval by the European Commission (EC), and most recently by the Medicines and Healthcare products Regulatory Agency (MHRA) in Great Britain, for a second indication for Jyseleca for patients suffering from UC, and we continue to roll out Jyseleca in RA and UC throughout Europe. Furthermore, following the completion of patient enrollment in the DIVERSITY Phase 3 program with filgotinib in CD, we anticipate topline results in the first half of 2023.

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

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

Beyond inflammation, we discontinued further development of ziritaxestat (GLPG1690) in IPF due to the unfavorable risk/benefit profile observed by an Independent Data Monitoring Committee (IDMC) in the Phase 3 trials. This not only was a major setback for Galapagos but most importantly for patients suffering from this debilitating disease for which current treatment options remain limited.

Finally, we completed the patient recruitment in our MANGROVE Phase 2 trial with our novel CFTR² inhibitor GLPG2737 in patients with ADPKD³, with results expected in the first half of 2023.

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

Bart Filius, President, COO and CFO of Galapagos, added: "We ended 2021 with a very strong balance sheet, providing us with the foundations for future growth. One year after receiving approval for Jyseleca in RA in Europe and Great Britain, we secured reimbursement in 14 countries, covering the major markets of Germany, France, Spain, Italy, and Great Britain. We reported €14.8 million of Jyseleca sales in Europe out of a total in-market performance of €25.7 million.

Following a strategic operational review in March 2021, we implemented a cost savings program of €150 million on a full year basis, which will take full effect in the course of 2022. Our operational cash burnⁱ in 2021 was €564.8 million, within our reduced guidance. For 2022 we anticipate a further significant reduction of our cash burn and expect to land between €450 and €490 million. This includes sales for Jyseleca that we anticipate between €65 and €75 million."

Details of the financial results

After the sale of our fee-for-service business (Fidelta) to Selvita on 4 January 2021, we only have one remaining reporting segment. The results of Fidelta, including the impact of the 2021 sale, are presented as "Net profit from discontinued operations" in our consolidated income statements for the years 2021 and 2020.

Revenues from continuing operations

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

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

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

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

Results from continuing operations

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

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

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

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

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

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

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

Net other financial income in 2021 amounted to €39.6 million, compared to net other financial loss of €134.2 million in 2020. Net other financial income in 2021 was primarily attributable to €57.2 million of currency exchange gains on our cash and cash equivalents in U.S. dollars, and to €8.8 million of net interest expenses. The other financial expenses also contained the effect of discounting our long term deferred income of €9.3 million.

Results from discontinued operations

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

Group net results

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

Cash position

Current financial investments and cash and cash equivalents totaled €4,703.2 million on 31 December 2021, as compared to €5,169.3 million on 31 December 2020 (including the cash and cash equivalents included in the assets as classified as held for sale).

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

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

Outlook 2022

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

In 2022, we expect reimbursement decisions in most key European markets for Jyseleca in UC. In Japan, collaboration partner Gilead expects a decision on the potential approval for Jyseleca in UC in the first half of 2022, which potentially could add a second indication for Jyseleca in this market.

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

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

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

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

Galapagos cautions the reader that forward-looking statements are not guarantees of future performance. Forward-looking statements are based on management's current expectations and beliefs and are subject to a number of risks, uncertainties and other important factors that may cause actual events, financial condition and liquidity, performance, or results to differ materially from any historic or future results, financial conditions and liquidity, performance or achievements expressed or implied by such forward-looking statements. When used in this press release, the words "anticipate", "believe", "could", "expect", "intend", "will", "plan", "potential", "should", and similar expressions are intented to identify forward-looking statements. In addition, even if Galapagos' results, performance, financial condition and liquidity, and the development of the industry in which it operates are consistent with such forward-looking statements, they may not be predictive of results or developments in future periods. Among the factors that may result in differences are that one or more assumptions, beliefs or expectations underlying management's guidance regarding our 2022 revenues, operating expenses and financial results may be incorrect (including one or more of its assumptions underlying its expense expectations), the inherent uncertainties associated with competitive developments, clinical trial and product development activities and regulatory approval requirements (including the risk that data from Galapagos' ongoing and planned clinical research programs in rheumatoid arthritis, Crohn's disease, ulcerative colitis, idiopathic pulmonary fibrosis, osteoarthritis, other inflammatory indications and kidney disease may not support registration or further development of its product candidates due to safety or efficacy concerns or other reasons), risks related to our reliance on collaborations with third parties (including, but not limited to, our collaboration partner Gilead), the risks related to the timing and implementation of the transition of the European commercialization responsibility of filgotinib from Gilead to us, the risk that the transition will not be completed on the currently contemplated timeline or at all, including the transfer of the supply chain, the risk that the transition will be more expensive to us than expected, the risk that the transition will not have the currently expected results for our business and results of operations, the risk that our projections and expectations regarding the commercial potential of filgotinib and any other product candidates may be inaccurate, the risk that our planned leadership transition may be disruptive to our business operations, the risk that we will be unable to successfully achieve the anticipated benefits from our planned leadership transition, the risk that we will encounter challenges retaining or attracting talent; risks related to continued regulatory review of filgotinib following approval by relevant regulatory authorities and the EMA's planned safety review of JAK inhibitors used to treat certain inflammatory disorders, including the risk that the EMA and/or other regulatory authorities determine that additional non-clinical or clinical studies are required with respect to filgotinib, the risk that the EMA may require that the marketing authorization for filgotinib in the EU be amended, the risk that the EMA may impose JAK class-based warnings, and the risk that the EMA's planned safety review may negatively impact acceptance of filgotinib by patients, the medical community, and healthcare payors, the risk that regulatory authorities may require additional post-approval trials of filgotinib or any other product candidates that are approved in the future, and risks related to the ongoing COVID-19 pandemic. For a discussion of other risks and uncertainties and other important factors any of which could cause our actual results to differ from those contained in the forward-looking statements, see the section entitled "Risk Factors" in our most recent Annual Report on Form 20-F filed with the U.S. Securities and Exchange Commission (SEC), as supplemented and/or modified by any other filings and reports that we have made or will make with the SEC in the future.

ⁱ The operational cash burn (or operational cash flow if this performance 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, in acquisitions or disposals of businesses; the movement in restricted cash and movement in current financial investments, if any, included in the net cash flows generated from/used in (-) investing activities.

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

The operational cash burn in 2021 amounted to €564.8 million and can be reconciled to our cash flow statement by considering the increase in cash and cash equivalents of €33.5 million, adjusted by (i) the cash proceeds from capital and share premium increase from the exercise of subscription rights by employees for €3.3 million, (ii) the net sale of current financial investments amounting to €566.4 million, and (iii) the cash in from sale of subsidiaries, net of cash disposed, of €28.7 million.
