Note 10. Commitments and contingencies

Purchase commitments

The Company has contractual arrangements with research and development organizations and suppliers; however, these contracts are generally cancelable on 30-60 days’ notice and the obligations under these contracts are largely based on services performed. The Company may also enter into contracts in the normal course of business with clinical research organizations for clinical trials, with contract manufacturing organizations for clinical supplies and with other vendors for preclinical studies, supplies and other services and products for operating purposes. These contracts generally provide for termination on notice. As of June 30, 2025 and December 31, 2024, there were no amounts accrued related to termination charges.

The Company has entered into a Biologics Master Services Agreement (the "WuXi Agreement") with WuXi Biologics (Hong Kong) Limited ("WuXi"). The WuXi Agreement provides the terms and conditions under which WuXi will coordinate the Company’s biologics development and manufacturing services. Pursuant to the WuXi Agreement, the Company may be required to pay WuXi a royalty percentage or a one-time milestone payment on global net sales of third-party manufactured products at the Company’s election. The royalty or one-time milestone payment is only payable if the Company does not use WuXi as the manufacturer in part, or in totality. As of June 30, 2025 and December 31, 2024, there are no minimum commitments under the WuXi Agreement. Additionally, as of June 30, 2025 and December 31, 2024, there are no royalties or milestones payable. The WuXi Agreement agreement will survive the Merger.

 

Operating leases

 

The Company’s operating leases are as follows:

 

An April 2016 lease, as amended, provides for a total of 2,684 square meters of office and laboratory space in Gosselies, Belgium and commenced in May 2016. In January 2021, the Company entered into an amendment to extend the lease, effective February 2021 with a termination date of January 2030. There is no option within the lease agreement to extend the termination date. In July 2025, the Company provided notice of termination of the lease and is obligated to pay rent for twelve months from such notice.
A November 2021 lease for 9,068 square feet of office space in Watertown, Massachusetts, which commenced in November 2021 and terminates in February 2027. The lease is subject to fixed-rate rent escalations. There is no option within the lease agreement to extend the termination date. The Company expects to provide notice of termination for this lease in the third quarter of 2025.
A July 2023 lease for 859 square meters of laboratory space in Gosselies, Belgium, for which the Company took occupancy in March 2024 and will terminate in December 2028. This lease does not contain any variable lease payments. There is no option within the lease agreement to extend the lease prior to the termination date. In July 2025, the Company provided notice of termination of the lease and is obligated to pay rent for six months from such notice.
Various car leases that the Company enters into from time to time. The life of each car lease ranges from 48 to 60 months.

The Company identified and assessed the following estimates in recognizing the operating lease right of use assets and corresponding liabilities.

Expected lease term: The expected lease term includes non-cancelable lease periods and, when applicable, periods covered by an option to extend the lease if the Company is reasonably certain to exercise that option, as well as periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise that option.

Incremental borrowing rate: As the discount rates in the Company’s lease are not implicit, management estimated the incremental borrowing rate based on the rate of interest the Company would have to pay to borrow a similar amount on a collateralized basis over a similar term.

Lease and non-lease components: The Company is required to pay fees for operating expenses in addition to monthly base rent for certain operating leases ("non-lease components"). The Company has not elected the practical expedient which allows non-lease components to be combined with lease components for all asset classes. Variable non-lease components are not included within the lease right-of-use asset and lease liability on the condensed consolidated balance sheet, and instead are reflected as expense in the period they are paid.

Rent expense was $0.4 million and $0.8 million for the three and six months ended June 30, 2025 and 2024, respectively.
