Subcontracting costs increased mainly related to CAR-T and small molecule programs in oncology, and costs for early termination of collaboration agreements. Personnel expenses increased due to severance costs, the increase in depreciation and impairment costs was due to impairment costs related to small molecules assets, of which €10.8 million was recorded on installations and machinery.

Cash position

Cash and cash equivalents and financial investments totaled €3,091.5 million on June 30, 2025 (€3,317.8 million on December 31, 2024).

Cash and cash equivalents and financial investments comprised cash at banks, term deposits, treasury bills (nil at June 30, 2025) and money market funds. Our cash management strategy monitors and optimizes our liquidity position. Our cash management strategy allows short-term deposits with an original maturity exceeding three months while monitoring all liquidity aspects.

All cash and cash equivalents are available upon maximum three months’ notice period and without significant penalty. Cash at banks were mainly composed of current accounts. Our credit risk is mitigated by selecting a panel of highly rated financial institutions for our deposits.

Current financial investments comprised €751.6 million of term deposits which all had an original maturity longer than three months and which are not available on demand within three months. Our current financial investments also comprised money market funds and treasury bills. Our portfolio of treasury bills contained only AAA rated paper, issued by France, Belgium and Europe. 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.

The decrease of the fair value of the equity instruments, which is due to exchange losses, of €6.0 million is reflected in the other reserves (other comprehensive income) in the consolidated equity. The valuation of all our equity investments is based on Level 3 assumptions as it includes investments in non-quoted companies. These investments are valued initially at fair value through the established purchase price between a willing buyer and seller. Subsequent valuation is based on internal and external evidence such as information from recent financing rounds, scientific updates and other valuation techniques.

The contingent consideration receivable relates to fair value of the future earn-outs to be obtained from Alfasigma for the sale of Jyseleca®. €7.0 million is presented on the line “Trade and other receivables” and €50.6 million is presented on the line “non-current contingent consideration receivable”. The total potential amount consists of sales-based milestone payments totaling €120 million and mid-single to mid-double-digit royalties on European sales. The valuation is based on Level 3 assumptions based on our best estimate of the expected earn-outs and sales milestones in the future, considering probability adjusted sales forecasts of Jyseleca® discounted using an appropriate discount rate. The fair value is reviewed at each reporting date and any changes are reflected in our consolidated income statement, in the line 'Net profit/loss (-) from discontinued operations, net of tax'. On June 30, 2025, the fair value of the future earn-outs was increased based on an adjustment of the sales forecasts of Jyseleca®  in Europe considering the evolution of the actual net sales. A change in expected sales by 15% would result in a change of €18.0 million in the total contingent consideration receivable on June 30, 2025.

 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 June 30, 2025 of these milestones amounted to €21.2 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 June 30, 2025 include a discount rate of 13.50% for the first two milestones and a discount rate of 14% for the third milestone, 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 €3.0 million in the total contingent consideration liability on June 30, 2025. As per June 30, 2025, changes were made to the key assumptions as compared to December 31, 2024 regarding the discount rate and the expected timing of the milestones. This impact, together with the discounting effect, was recognized in the financial results.

We refer to critical accounting judgements and key sources of estimation uncertainty for details about the fair value of the convertible loan.
