13.  Leases

The Company has commitments under operating leases for laboratory, warehouse, clinical trial sites and office space. The Company also has finance leases for manufacturing space and office and laboratory equipment. The Company’s leases have initial lease terms ranging from 1.5 years to 191 years. Certain lease agreements contain provisions for future rent increases. Payments due under the lease contracts include fixed payments.

Total rent expense recorded under these leases was $4.8 million and $5.6 million for the years ended December 31, 2025 and 2024, respectively.

The Company entered into a lease agreement for laboratory space in March 2025 with an initial lease term of 91 months. The Company also entered into a lease agreement for office space in July 2025 with an initial lease term of 39 months. The lease for the laboratory space contains provisions for tenant allowances and future rent increases. The Company took possession of both spaces in August 2025 and recognized initial operating lease right-of-use assets in the amount of $8.2 million and corresponding lease liabilities in the amount of $8.0 million, in connection with these leases, which are included in the right-of-use assets and lease obligations in the consolidated balance sheets as of December 31, 2025. The lease liabilities have been measured using the incremental borrowing rate (“IBR”) rather than the rate implicit in the lease agreements, as the implicit rates could not be readily determined. The IBR applied to both leases reflects the parent company’s borrowing rate as the Company considers it to be a more appropriate reflection of the financing rate that would be available to the consolidated group, rather than the rates specific to the subsidiary that is the lessee under the agreements. There were no leases recognized during the year ended December 31, 2024. During the year ended December 31, 2025, the Company determined that it was reasonably certain to exercise its early termination option on an operating lease for laboratory and office space, resulting in a remeasurement of the ROU asset and lease liability reflected in the accompanying consolidated balance sheets. The lease was terminated August 31, 2025.

Eight clinical trial site leases were assigned to Johnson & Johnson Innovative Medicine during the year ended December 31, 2024 in connection with the Asset Purchase Agreement and related agreements.
