7. Contract liabilities

Contract liabilities represent the Group’s obligation to transfer services to a customer for which the Group has received advanced consideration, before the performance obligation has been satisfied. These liabilities are recognized when a customer prepays for services or when the Group has an unconditional right to consideration before the performance obligation is fulfilled.

Contract liabilities comprise entirely of advance consideration received from customers (deferred revenue) in respect of the AstraZeneca collaboration as of June 30, 2025. The current contract liabilities represent the amount of estimated revenue to be reported in the next 12 months related to amounts invoiced to its partners, while the non-current portion represents everything beyond 12 months. Current and non-current contract liabilities include future revenue from collaboration recharged expenses, upfront payments, and milestones achieved to June 30, 2025.
