Leases
Lease Commitments
In May 2025, the Company amended the operating lease for its corporate headquarters in Skokie IL., the terms of which terminated certain floors of the leased space and was treated as a lease modification as of the effective date. The partial lease termination of the corporate headquarters leased space resulted in a reduction in the Company’s future minimum fixed lease obligations as of the lease modification date. As a result of the partial lease termination, the Company remeasured its operating lease liabilities and recorded a decrease of $13,085 to reflect the reduced lease payments. The Company also recorded a decrease to right-of-use assets of $13,025 based on the proportionate decrease in the right-of-use asset, which resulted in a gain of $60 recognized in other income (expense), net within the Company’s consolidated statements of operations and comprehensive loss for the year ended December 31, 2025. The lease liability was remeasured using a revised incremental borrowing rate (“IBR”) of 8.0% as of the amendment date in determining the present value of lease payments. The Company estimated the IBR based upon comparing interest rates available in the market for similar borrowings and the credit quality of the Company.
Under the terms of the lease agreement for the Company’s headquarters, the Company was required to deliver the security deposit in the form of a letter of credit to the landlord no later than June 30, 2025. Until such delivery, the obligation represents a commitment under the lease agreement. The letter of credit will not be drawn upon unless the Company fails to perform under the lease terms.
The Company leases certain office space and laboratory facilities. The Company’s lease agreements typically do not contain any significant guarantees of asset values at the end of a lease, renewal options or restrictive covenants. Pursuant to ASC 842, Leases, all leases are classified as operating leases.
