Management to host a conference call tomorrow, November 6, 2025, at 14:00 CET / 08:00 AM ET 

Mechelen, Belgium; November 5, 2025, 22:01 CET; regulated information – Galapagos NV (Euronext & Nasdaq: GLPG) today announced its financial results for the first nine months of 2025, and provided a third quarter and recent business update.  

“We successfully delivered on our commitment to define a clear path forward for Galapagos following the completion of the strategic review of our cell therapy business,” said Henry Gosebruch, CEO of Galapagos. “We have built a team with world-class strategy and business development capabilities as we focus on disciplined capital stewardship and transformative business development, supporting a stronger and sustainable future for Galapagos.”  

Gosebruch added, “Looking ahead, we will seek to strategically deploy our capital in a disciplined manner by pursuing value-accretive transactions. Our business development team is actively evaluating a broader array of opportunities with priority given to promising small molecule and biologics programs with proof-of-concept in immunology and oncology and potential to deliver meaningful patient impact. We believe our partnership with Gilead can be a strategic advantage as we pursue these opportunities. We expect to focus on transactions that can deliver meaningful value to patients and shareholders while ensuring effective risk diversification.”  

“We ended the third quarter with a strong balance sheet that provides us with the flexibility to allocate capital strategically and invest in future business development opportunities,” said Aaron Cox, CFO of Galapagos. “We expect to end the year with approximately €2.975 billion to €3.025 billion in cash and financial investments, excluding any business development activities and currency fluctuations. If the intention to wind down the cell therapy business is implemented and the process is completed, we would expect to be cash flow neutral to positive by the end of 2026, excluding any business development activities and currency fluctuations.”  

Third quarter 2025 and recent business update 

Outcome of the Strategic Alternatives Process for Galapagos’ Cell Therapy Business

• On October 21, 2025, Galapagos announced its intention to wind down its cell therapy business as part of the Company’s ongoing transformation. This intention is subject to the conclusion of consultations with works councils in Belgium and the Netherlands, during which Galapagos will continue to operate the business. Galapagos would consider any viable proposal to acquire all, or part of the cell therapy business, if such a proposal were to emerge during the wind down process.
• If ultimately implemented, the wind down would impact approximately 365 employees across Europe, the U.S., and China, and would include the closure of sites in Leiden (the Netherlands), Basel (Switzerland), Princeton and Pittsburgh (U.S.), and Shanghai (China).
• The remaining Galapagos organization is expected to be a lean organization of approximately 35-40 employees by the end of 2026, repositioned for long-term growth through transformational business development, while maintaining a dedicated presence at its headquarters in Mechelen, Belgium and its hub in Chicago, IL (U.S.).

Corporate

• Senior leadership has been further strengthened with the appointment of Fred Blakeslee as Executive Vice President and General Counsel on October 16, and Sooin Kwon as Chief Business Officer and Dan Grossman as Chief Strategy Officer, effective August 4. These appointments have added strong corporate, business development and strategic assessment capabilities to the leadership team.
• As part of the Company’s ongoing commitment to long-term governance and strategic continuity, several changes to the Board of Directors were announced:
  • Dawn Svoronos and Jane Griffiths were appointed by way of co-optation as Non-Executive Independent Directors, replacing Peter Guenter and Simon Sturge, effective July 28.
  • Dr. Neil Johnston has been appointed to the Board of Directors by way of co-optation as Non-Executive Independent Director, effective November 1. In addition, Devang Bhuva, current Senior Vice President of Corporate Development and Alliance Management at Gilead, has been appointed by way of co-optation as Non-Executive Non-Independent Director, effective November 1. In connection with these co-optations, Non-Executive Independent Directors Dr. Elisabeth Svanberg and Dr. Susanne Schaffert, and Non-Executive Non-Independent Director and current CFO of Gilead, Andrew Dickinson, stepped down, effective November 1. An additional Non-Executive Independent Director is expected to be appointed in the near future as part of the Board’s commitment to maintain a balanced, diversified Board composition with appropriate capabilities and profiles.

Clinical Pipeline
GLPG5101, a CD19 CAR-T candidate in Phase 1/2 across eight hematological malignancies

• Two abstracts have been accepted for an oral and poster presentation at the 67th American Society of Hematology (ASH) Annual Meeting and Exposition, to be held in Orlando, from December 6-9.
• In August, the FDA granted RMAT designation to GLPG5101 for the treatment of relapsed/refractory mantle cell lymphoma. 

GLPG3667, a small molecule TYK2 inhibitor in two Phase 3-enabling studies in systemic lupus erythematosus (SLE) and dermatomyositis (DM)

• Both the SLE and DM studies have progressed well, and topline data from both studies are expected in early 2026.
• On October 26, Galapagos presented in vitro pharmacology data at the American College of Rheumatology (ACR) Convergence 2025, suggesting differentiation of GLPG3667 from other TYK2 inhibitors at their clinical dose regimens. 

Financial performance

Key figures for the first nine months of 2025 (consolidated)
(€ millions, except basic & diluted earnings/loss (-) per share)

Details of the financial results for the first nine months of 2025
Total operating loss from continuing operations for the first nine months of 2025, amounted to €462.2 million, compared to an operating loss of €125.6 million for the first nine months of 2024. This operating loss was negatively impacted by an impairment on the cell therapy business of €204.8 million as a result of the Company’s previously announced strategic alternatives process for the cell therapy business, and the executed strategic reorganization announced in January 2025, for €135.5 million. The latter is reflected in severance costs of €47.5 million, costs for early termination of collaborations of €45.5 million, impairment on fixed assets related to small molecules activities of €9.5 million, deal costs of €21.4 million, €9.8 million accelerated non-cash cost recognition for subscription right plans related to good leavers and €1.8 million other operating expenses.

• Total net revenues amounted to €211.4 million for the first nine months of 2025, compared to €200.1 million for the first nine months of 2024. The revenue recognition related to the exclusive access rights granted to Gilead for Galapagos’ drug discovery platform amounted to €172.6 million for the first nine months, for both 2025 and 2024. The deferred income balance at September 30, 2025, includes €896.4 million allocated to the Company’s drug discovery platform. Royalties on Jyseleca® from Gilead amounted to €8.3 million for the first nine months of 2025 (€8.4 million for the same period last year).
• Cost of sales amounted to €29.3 million for the first nine months of 2025, compared to €19.1 million for the first nine months of 2024, 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 amounted to €351.9 million for the first nine months of 2025, compared to €238.2 million for the first nine months of 2024. Increased personnel expenses (mainly related to severance costs), impairment on fixed assets (related to small molecules programs) and costs for early termination of collaboration agreements lead to this increase in R&D expenses.
• S&M and G&A expenses amounted to €109.0 million for the first nine months of 2025, compared to €93.2 million for the first nine months of 2024. This increase was mainly due to higher personnel costs (primarily severance costs) and higher legal and professional fees (deal costs).
• Impairment of cell therapy business is a result of the Company’s previously announced strategic alternatives process for the cell therapy business whereby the Company assessed the cell therapy business associated assets’ recoverable amount in accordance with IAS 36. The recoverable amount was estimated lower than the assets’ carrying value. As a result, the Company recognized an impairment loss of €204.8 million, thereby aligning the cell therapy assets’ book value with the Company’s strategic intention to wind down the cell therapy business, which resulted in a full impairment of both the associated goodwill and intangible assets and a partial impairment of property, plant and equipment.
• Other operating result amounted to €21.4 million for the first nine months of 2025, compared to €24.8 million for the first nine months of 2024, mainly driven by lower grant and R&D incentives income and no recharges to Alfasigma. 

Net financial loss amounted to €20.1 million for the first nine months of 2025, compared to net financial income of €103.5 million for the first nine months of 2024.

• Fair value adjustments and net currency exchange results amounted to a negative amount of €50.5 million for the first nine months of 2025, compared to positive fair value adjustments and net currency exchange gains of €31.8 million for the first nine months of 2024, and were primarily attributable to €29.1 million of negative changes in fair value of financial investments, €44.0 million of unrealized currency exchange losses on our cash and cash equivalents and financial investments at amortized cost in U.S. dollars, partly offset by a positive effect of €22.7 million as consequence of the settlement of a hedging instrument.
• Net other financial income amounted to €30.4 million for the first nine months of 2025, compared to net other financial income of €71.7 million for the first nine months of 2024. Interest income amounted to €31.4 million for the first nine months of 2025, compared to €70.6 million of interest income for the first nine months of 2024, due to a decrease in the interest rates and a shift from investments in term deposits generating financial income to investments in money market funds generating fair value changes. Fair value gains and interest income derived from cash, cash equivalents and financial investments excluding any currency exchange results amounted to €77.2 million for the first nine months of 2025 (compared to €108.9 million for the same period last year). 

Income taxes amounted to €19.3 million for the first nine months of 2025. The increase is mainly explained by the reversal of the deferred tax liabilities linked to capitalized intangible assets related to the cell therapy business, as the Company recorded an impairment on these intangible assets.

The Company reported a net loss from continuing operations of €463.0 million for the first nine months of 2025, compared to a net loss from its continuing operations of €20.4 million for the first nine months of 2024.

Net profit from discontinued operations related to Jyseleca® amounted to €1.7 million for the first nine months of 2025, compared to net profit amounting to €69.2 million for the first nine months of 2024. The net result for discontinued operations included €10.4 million of R&D expenses primarily related to the final settlement of disputed expenses with Alfasigma, and €11.4 million of other operating income related to a fair value adjustment of the contingent consideration receivable from Alfasigma as a consequence of an adjusted sales forecast. The operating profit from discontinued operations for the first nine months of 2024, was mainly related to the gain on the sale of the Jyseleca® business to Alfasigma of €52.3 million.

Galapagos reported a net loss of €461.3 million for the first nine months of 2025, compared to a net profit of €48.8 million for the first nine months of 2024.

Cash position

Financial investments and cash and cash equivalents totaled €3,050.1 million on September 30, 2025, as compared to €3,317.8 million on December 31, 2024. The cash and cash equivalents and financial investments included $2,161.1 million held in U.S. dollars ($726.9 million on December 31, 2024) which could generate foreign exchange gains or losses in the financial results in accordance with the fluctuation of the EUR/U.S. dollar exchange rate as the Company’s functional currency is EUR (translated at a rate of 1.1741 €/$ at September 30, 2025).

Total net decrease in cash and cash equivalents and financial investments amounted to €267.7 million during the first nine months of 2025, compared to a net decrease of €345.7 million during the first nine months of 2024. This net decrease was composed of (i) €145.1 million of operational cash burn, which includes cash in of €77.7 million related to the return on financial investments) (ii) €118.6 million of negative exchange rate differences, positive changes in fair value of current financial investments, variation in accrued interest income, (iii) €20.0 million convertible loan issued to a third party, and (iv) €16.0 million of net cash is related to the sale of subsidiaries.

Financial guidance

Galapagos anticipates ending 2025 with approximately €2.975 billion to €3.025 billion in cash, cash equivalents and financial investments, excluding any business development activities and currency fluctuations. In the event that the Board would effectively proceed with a full wind down decision of the cell therapy business (i.e., if the intention is confirmed after works council processes), the Company would expect to incur the following spend related to the cell therapy business: €100 million to €125 million of operating cash impact from Q4 2025 through 2026 and €150 million to €200 million of one-time restructuring cash impact in 2026. If the intention to wind down is implemented and the process is completed, the Company would expect to be cash flow neutral to positive by the end of 2026, excluding any business development activities and currency fluctuations.

The operational cash burn (or operational cash flow if this liquidity measure is positive) is equal to the increase or decrease in the 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 acquisition of financial assets held at fair value through other comprehensive income; the movement in restricted cash and movement in 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 or disposal of businesses, if any, included in the net cash flows generated from/used in (-) operating activities.
This alternative liquidity measure is in the view of the Company an important metric for a biotech company in the development stage. The operational cash burn for the first nine months of 2025, amounted to €145.1 million and can be reconciled to the cash flow statement by considering the increase in cash and cash equivalents of €3.3 million, adjusted by (i) the net sale of financial investments amounting to €152.4 million, (ii) the cash-in related to the sale/acquisition of subsidiaries of €16.0 million, and (iii) the convertible loan issued to a third party of €20.0 million.
