For more information, please visit: . About ZYMFENTRA® (infliximab-dyyb) [1] ZYMFENTRA is a prescription medicine used as an injection under the skin (subcutaneous injection) by adults for the maintenance treatment of: moderately to severely active ulcerative colitis following treatment with an infliximab product given by intravenous infusion (IV), moderately to severely active Crohn's disease following treatment with an infliximab product given by intravenous infusion (IV). ZYMFENTRA blocks the action of tumor necrosis factor-alpha (TNF-alpha), a protein that can be overproduced in response to certain diseases and cause the immune system to attack normal, healthy parts of the body. ZYMFENTRA® (infliximab-dyyb) was approved by the FDA through the Biologics License Application (BLA) under the 351 (a) pathway of the Public Health Service Act (a "stand-alone" BLA). ZYMFENTRA is considered a new biologic with a first-approved subcutaneous administration form and thus will be under patent protection for its dosage form by 2037 and for its route of administration by 2040. Indication and Important Safety Information ZYMFENTRA is a prescription medicine indicated in adults for maintenance treatment of: Moderately to severely active Crohn's disease following treatment with an infliximab product administered intravenously. Moderately to severely active ulcerative colitis following treatment with an infliximab product administered intravenously. It is not known if ZYMFENTRA is safe and effective in children under 18 years of age. What is the most important information I should know about ZYMFENTRA? SERIOUS INFECTIONS Patients treated with ZYMFENTRA are at increased risk for developing serious infections involving various organ systems and sites that may lead to hospitalization or death. Discontinue ZYMFENTRA if a patient develops a serious infection or sepsis. Reported infections include: Active tuberculosis (TB), including reactivation of latent TB. Patients frequently presented with disseminated or extrapulmonary disease. Patients should be tested for latent TB before and during treatment with ZYMFENTRA. Treatment for latent infection should be initiated prior to treatment with ZYMFENTRA. Invasive fungal infections, including histoplasmosis, coccidioidomycosis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patients may present with disseminated, rather than localized, disease. Empiric anti-fungal therapy should be considered in patients at risk for invasive fungal infections who develop severe systemic illness. Bacterial, viral, and other infections due to opportunistic pathogens, including Legionella and Listeria. The risks and benefits of treatment with ZYMFENTRA should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection. Closely monitor patients for the development of signs and symptoms of infection during and after treatment with ZYMFENTRA, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy. Risk of infection may be higher in patients greater than 65 years of age, patients with comorbid conditions and/or patients taking concomitant immunosuppressant therapy. In clinical trials, other serious infections observed in patients treated with infliximab included arthritis bacterial, pneumonia, and urinary tract infection. MALIGNANCIES Malignancies, some fatal, have been reported in children, adolescents, and young adults treated with TNF blockers, including infliximab products. Approximately half of these cases were lymphomas, including Hodgkin's and non-Hodgkin's lymphoma. The other cases represented a variety of malignancies, including rare malignancies that are usually associated with immunosuppression and malignancies that are not usually observed in children and adolescents. The malignancies occurred after a median of 30 months after the first dose of therapy. Most of the patients were receiving concomitant immunosuppressants. Post-marketing cases of hepatosplenic T-cell lymphoma, a rare type of T-cell lymphoma, have been reported in patients treated with TNF blockers, including infliximab products. These cases have had a very aggressive disease course and have been fatal. The majority of reported cases have occurred in patients with Crohn's disease or ulcerative colitis, and most were in adolescent and young adult males. Almost all of these patients had received treatment with azathioprine or 6-mercaptopurine concomitantly with a TNF blocker at or prior to diagnosis. Carefully assess the risks and benefits of treatment with ZYMFENTRA, especially in these patient types. In clinical trials of all TNF blockers, more cases of malignancies were observed compared with controls and the expected rate in the general population. In clinical trials of some TNF blockers, including infliximab products, more cases of other malignancies were observed compared with controls. As the potential role of TNF blocker therapy in the development of malignancies is not known, caution should be exercised when considering treatment of patients with a current or a past history of malignancy. Melanoma and Merkel cell carcinoma have been reported in patients treated with TNF blocker therapy, including infliximab products. Periodic skin examination is recommended for all patients, particularly those with risk factors for skin cancer. CONTRAINDICATIONS ZYMFENTRA is contraindicated in patients with a previous severe hypersensitivity reaction to infliximab-dyyb, other infliximab products, any of the inactive ingredients of ZYMFENTRA or any murine proteins (severe hypersensitivity reactions have included anaphylaxis, hypotension, and serum sickness). HEPATITIS B VIRUS REACTIVATION TNF blockers, including infliximab products, have been associated with reactivation of hepatitis B virus (HBV) in patients who are chronic carriers. Some cases were fatal. Patients should be tested for HBV infection before initiating ZYMFENTRA. For patients who test positive, consult a physician with expertise in the treatment of hepatitis B. Exercise caution when prescribing ZYMFENTRA for patients identified as carriers of HBV, and monitor closely for active HBV infection during and following termination of therapy with ZYMFENTRA. Discontinue ZYMFENTRA in patients who develop HBV reactivation and initiate antiviral therapy with appropriate supportive treatment. Exercise caution when considering resumption of ZYMFENTRA, and monitor patients closely. HEPATOTOXICITY Hepatobiliary disorders, including acute liver failure, jaundice abnormal hepatic function, hepatic steatosis, hepatitis, hepatotoxicity, hyperbilirubinemia, and non-alcoholic fatty liver, have been reported in patients receiving infliximab products post-marketing. Some cases were fatal or required liver transplant. Aminotransferase elevations were not noted prior to discovery of liver injury in many cases. Patients with symptoms or signs of liver dysfunction should be evaluated for evidence of liver injury. If jaundice and/or marked liver enzyme elevations (eg, ≥5 times the upper limit of normal) develop, ZYMFENTRA should be discontinued, and a thorough investigation of the abnormality should be undertaken. CONGESTIVE HEART FAILURE Cases of worsening congestive heart failure (CHF) and new onset CHF have been reported with TNF blockers. Some cases had a fatal outcome. In several exploratory trials of other TNF blockers in the treatment of CHF, there were greater proportions of TNF-blocker-treated patients who had CHF exacerbations requiring hospitalization or increased mortality. ZYMFENTRA has not been studied in patients with a history of CHF and ZYMFENTRA should be used with caution in patients with CHF. HEMATOLOGIC REACTION Cases of leukopenia, neutropenia, thrombocytopenia, and pancytopenia (some fatal) have been reported. The causal relationship to infliximab-product therapy remains unclear. Exercise caution in patients who have ongoing or a history of significant hematologic abnormalities. Advise patients to seek immediate medical attention if they develop signs and symptoms of blood dyscrasias or infection. Consider discontinuation of ZYMFENTRA in patients who develop significant hematologic abnormalities. HYPERSENSITIVITY AND OTHER ADMINISTRATION REACTIONS In post-marketing experience, serious systemic hypersensitivity reactions (including anaphylaxis, hypotension, and serum sickness) have been reported following administration of infliximab products. If an anaphylactic or other clinically significant hypersensitivity reaction occurs, institute appropriate therapy and discontinue ZYMFENTRA. INJECTION SITE REACTIONS In clinical studies, localized injection-site reactions were reported following administration of ZYMFENTRA. If a clinically significant injection-site reaction occurs, institute appropriate therapy and discontinue ZYMFENTRA. NEUROLOGIC REACTIONS Agents that inhibit TNF have been associated with central nervous system (CNS) manifestation of systemic vasculitis, seizure, and new onset or exacerbation of CNS demyelinating disorders, including multiple sclerosis and optic neuritis, and peripheral demyelinating disorders, including Guillain-Barré syndrome. Exercise caution when considering ZYMFENTRA in patients with these disorders and consider discontinuation if these disorders develop. RISK OF INFECTION WITH CONCURRENT ADMINISTRATION OF OTHER BIOLOGICS PRODUCTS Serious infections and neutropenia have been reported with concurrent use of ZYMFENTRA with other immunosuppressive biological products. The concurrent use of ZYMFENTRA with other immunosuppressive biological products used to treat UC and CD may increase the risk of infection and is not recommended. RISK OF ADDITIVE IMMUNOSUPPRESSIVE EFFECTS FROM PRIOR BIOLOGICAL PRODUCTS Consider the half-life and mode of action of prior biological products to avoid unintended additive immunosuppressive effects when initiating ZYMFENTRA. AUTOIMMUNITY Treatment with TNF blockers may result in the formation of autoantibodies and in the development of a lupus-like syndrome. Discontinue ZYMFENTRA treatment if symptoms of a lupus-like syndrome develop. VACCINATIONS AND USE OF LIVE VACCINES/THERAPEUTIC INFECTIOUS AGENTS Prior to initiating ZYMFENTRA, update vaccinations in accordance with current vaccination guidelines. Live vaccines or therapeutic infectious agents should not be given with ZYMFENTRA due to the possibility of clinical infections, including disseminated infections. At least a 6-month waiting period following birth is recommended before the administration of any live vaccine to infants exposed in utero to ZYMFENTRA. ADVERSE REACTIONS In clinical trials with ZYMFENTRA, the most common adverse reactions occurring in ≥3% of ZYMFENTRA -treated patients included site reactions, COVID-19, anemia, arthralgia, infection site reaction, increased alanine aminotransferase and abdominal pain for UC, and COVID-19, headache, upper respiratory tract infection, injection site reaction, diarrhea, increased blood creatine phosphokinase, arthralgia, increased alanine aminotransferase, hypertension, urinary tract infection, neutropenia, dizziness and leukopenia for CD.

This includes more than 20 programs, with four assets in clinical development across 11 indications, and more than 15 preclinical programs in oncology and immunology. We achieved a major regulatory milestone with the FDA clearance of the Investigational New Drug (IND) application for the Phase 1/2 ATALANTA-1 study of our CD19 CAR-T candidate, GLPG5101, in relapsed/refractory non-Hodgkin lymphoma (R/R NHL), marking an important step forward in our cell therapy pipeline using our innovative decentralized manufacturing platform.We resumed recruitment in the Phase 1/2 PAPILIO-1 study with our BCMA CAR-T candidate, GLPG5301, in relapsed/refractory multiple myeloma (R/R MM). As part of our collaboration agreement with Blood Centers of America (BCA), we selected Excellos in the San Diego area as the first decentralized manufacturing unit (DMU) within BCA’s nationwide network to manufacture GLPG5101 for the ATALANTA-1 study sites in the region. We further advanced our early-stage proprietary pipeline and progressed a next-generation armed, bispecific CAR-T candidate in hemato-oncology and a potential best-in-class small molecule candidate in immunology into IND-enabling studies, targeting clinical development in 2025-2026.We have €3.3 billion in cash and financial investments as of September 30, 2024, supporting our pipeline. We reconfirm the full-year 2024 cash burni guidance of €370 million to €410 million. Webcast presentation on October 31, 2024, at 13:00 CET / 8:00 am ET, www.glpg.com Mechelen, Belgium; October 30, 2024, 21:01 CET; regulated information – Galapagos NV (Euronext & NASDAQ: GLPG) today announced financial results for the first nine months of 2024 and provided a business update. “I am proud of our team’s commitment in executing our Forward, Faster strategy,” said Paul Stoffels1, MD, Galapagos’ CEO and Chair of the Board of Directors. “The FDA's clearance of the ATALANTA-1 study of GLPG5101, produced on our decentralized manufacturing platform in patients with relapsed/refractory non-Hodgkin lymphoma, marks a pivotal step towards realizing our vision of transforming patient outcomes through life-changing science and innovation. This is the first-ever FDA clearance for a clinical study in the U.S. with a fresh CAR-T product candidate delivered in a median vein-to-vein time of seven days. We remain focused on advancing our clinical pipeline in 11 indications and our potential best-in-class early-stage programs across multiple modalities and indications.” “With more than 20 active cell therapy and small molecule programs in oncology and immunology, we are accelerating our internal pipeline while we continue to assess business development opportunities. We reaffirm our 2024 cash burn guidance in the range of €370-410 million,” Thad Huston, Galapagos’ CFO and COO, added. Third quarter and recent business highlights and anticipated milestonesRegulatory and pipeline: The investigational new drug (IND) application for the Phase 1/2 ATALANTA-1 study of our CD19 candidate, GLPG5101, in R/R NHL has been cleared by the U.S. Food and Drug Administration (FDA) and our goal is to activate clinical study sites and start enrolling patients in the U.S. before the end of 2024.We expect to submit an IND in early 2025 for the Phase 1/2 EUPLAGIA-1 study in relapsed/refractory chronic lymphocytic leukemia (R/R CLL) and Richter transformation (RT) of our CD19 CAR-T candidate, GLPG5201.Following the submission of a Clinical Trial Application (CTA) to the European Medicines Agency (EMA) for the Phase 2 dose expansion study of GLPG5201 in R/R CLL and RT, we aim to start enrolling patients in 2025.We resumed enrolment in the Phase 1/2 PAPILIO-1 study of our BCMA CAR-T candidate, GLPG5301, in R/R MM.We will present new data from the ATALANTA-1 and EUPLAGIA-1 studies along with pre-clinical data for uza-cel, our TCR-T cell therapy candidate produced on our decentralized manufacturing platform in collaboration with Adaptimmune, at the American Society of Hematology (ASH) Annual Meeting in December.We continued enrolling patients in the ongoing Phase 2 GALARISSO study in dermatomyositis (DM) and the Phase 2 GALACELA study in systemic lupus erythematosus (SLE) with our oral small molecule TYK2 inhibitor, GLPG3667.We further advanced our early-stage proprietary pipeline and progressed a next-generation armed, bispecific CAR-T candidate in hemato-oncology and a potential best-in-class small molecule candidate in immunology into IND-enabling studies, targeting clinical development in 2025-2026.We are accelerating our early-stage pipeline of more than 15 programs in oncology and immunology with the objective of launching at least four IND/CTA-enabling studies in 2025 across different modalities and indications. From 2026 onward, our ambition is to fuel the clinical pipeline with at least two new clinical assets annually in various indications and across our cell therapy and small molecule portfolio. Operational: As part of our collaboration agreement with Blood Centers of America (BCA), we selected Excellos in the San Diego area as the first decentralized manufacturing unit (DMU) within BCA’s nationwide network to manufacture GLPG5101 for the ATALANTA-1 study sites in the region.We continue to expand our DMU network in Europe and the U.S. to manufacture our cell therapy candidates for clinical development and to support pivotal and commercial readiness. External innovation: We are exploring strategic partnerships, early-stage research collaborations, licensing, and bolt-on acquisitions in areas of high unmet medical need to accelerate our cell therapy and small molecule pipeline in oncology and immunology. Corporate: The Board of Directors appointed Mr. Oleg Nodelman as Non-Executive Non-Independent Director by way of co-optation effective October 7, 2024, replacing Dr. Dan Baker who stepped down on October 6, 2024.

The comparative first nine months of 2023 have been restated accordingly for the presentation of the results related to the Jyseleca® business. Results from our continuing operationsTotal operating loss from continuing operations for the nine months ended September 30, 2024, was €125.6 million, compared to an operating loss of €41.9 million for the nine months ended September 30, 2023. Total net revenues for the nine months ended September 30, 2024, amounted to €200.1 million, compared to €179.8 million for the nine months ended September 30, 2023. The revenue recognition related to the exclusive access rights granted to Gilead for our drug discovery platform amounted to €172.7 million for the first nine months of both 2024 and 2023. Our deferred income balance on September 30, 2024, includes €1.1 billion allocated to our drug discovery platform that is recognized linearly over the remaining period of our 10-year collaboration. Cost of sales for the nine months ended September 30, 2024, amounted to €19.1 million and related to the supply of Jyseleca® to Alfasigma under the transition agreement. The related revenues are reported in total net revenues.R&D expenses in the first nine months of 2024 amounted to €238.2 million, compared to €167.2 million for the first nine months of 2023. This increase was primarily explained by higher costs for cell therapy and small molecule programs in oncology.G&A and S&M expenses amounted to €93.2 million in the first nine months of 2024, compared to €87.4 million in the first nine months of 2023. This increase was primarily due to an increase in legal and professional fees, mainly related to business development activities and due to an increase in S&M expenses due to investments in strategic marketing for oncology. Both increases were partly offset by a decrease in G&A personnel expenses, mainly due to a decreased cost for our subscription rights plans.Other operating income amounted to €24.8 million in the first nine months of 2024, compared to €32.9 million for the same period last year. This decrease is mainly driven by lower grants and R&D incentives. Net financial income in the first nine months of 2024 amounted to €103.5 million, compared to net financial income of €90.3 million for the first nine months of 2023. Fair value adjustments and net currency exchange results in the first nine months of 2024 amounted to €31.8 million, compared to fair value adjustments and net currency exchange gains of €36.3 million for the first nine months of 2023, and were primarily attributable to €3.1 million of unrealized currency exchange losses on our cash and cash equivalents and current financial investments at amortized cost in U.S. dollars, and to €35.7 million of positive changes in fair value of current financial investments.Net other financial income in the first nine months of 2024 amounted to €71.7 million, compared to net other financial income of €54.0 million for the first nine months of 2023, and was primarily attributable to €70.6 million of interest income, which increased significantly due to the increase in interest rates. Net tax income in the first nine months of 2024 amounted to €1.7 million, compared to net tax expenses of €12.2 million for the first nine months of 2023. The net tax expenses in 2023 were primarily due to the re-assessment of net deferred tax liabilities and corporate income tax payables as a result of a one-off intercompany transaction. Net loss from continuing operations for the first nine months of 2024 was €20.4 million, compared to a net profit from continuing operations of €36.2 million for the first nine months of 2023.Results from discontinued operations (€ millions) Nine months ended September 30 % Change 2024 2023 Product net sales 11.4 82.1 -86% Collaboration revenues 26.0 187.0 -86% Total net revenues 37.4 269.1 -86% Cost of sales (2.2) (13.5) -84% R&D expenses (13.6) (145.0) -91% G&A and S&M expenses (10.8) (94.7) -89% Other operating income 55.2 7.1 Operating profit 66.0 23.0 Net financial result 3.3 (3.7) Income taxes (0.1) (1.4) Net profit from discontinued operations 69.2 17.9 Total operating profit from discontinued operations amounted to €66.0 million in the first nine months of 2024, compared to an operating profit of €23.0 million in the same period last year.

The operational cash burn for the first nine months of 2024 amounted to €321.3 million and can be reconciled to our cash flow statement by considering the decrease in cash and cash equivalents of €111.8 million, adjusted by (i) the net sale of current financial investments amounting to €260.2 million, (ii) the cash-out related to the sale of subsidiaries of €13.8 million, and (iii) the acquisition of financial assets held at fair value through other comprehensive income of €36.9 million.ii General and administrativeiii Sales and marketing Attachment Galapagos Reports Third Quarter 2024 Financial Results and Provides Business Update
