The Company’s leases consist primarily of operating leases for administrative office space, research and development facilities, manufacturing facilities, and sales offices in various countries around the world. The Company determines if an arrangement is a lease at inception. Some lease agreements contain lease and non-lease components, which are accounted for as a single lease component. Total rent expense was $0.2 million and $0.4 million for the three and six months ended June 30, 2025, respectively, and $0.2 million and $0.4 million for the three and six months ended June 30, 2024, respectively.

Initial lease terms are determined at commencement and may include options to extend or terminate the lease when it is reasonably certain the Company will exercise the option. Remaining lease terms range from one to three years, some of which include options to extend for up to five years. Leases with an initial term of 12 months or less are not recorded on the condensed consolidated balance sheets. As the Company’s leases do not provide an implicit rate, the present value of future lease payments is determined using the Company’s incremental borrowing rate based on information available at the lease commencement date.
