8. Leases

As of June 30, 2026, the Company maintained one finance lease for equipment and two operating leases for real estate. The operating leases had terms of 36 and 37 months and included one or more options to extend the duration of the agreements. These operating leases are included in "Other assets" on the Company's condensed consolidated balance sheets and represent the Company's right to use the underlying assets for the term of the leases. The Company's obligation to make lease payments are included in "Lease liability, current portion" and "Lease liability, non-current portion" on the Company's condensed consolidated balance sheets.

On December 9, 2025, the Company extended its operating lease for its headquarters located at 5370 Kietzke Lane, Reno, NV. The lease extension was determined to be a lease modification that qualified as a change of accounting on the existing lease and not a separate contract. As such, the Right-of-Use (“ROU”) assets and operating lease liabilities were remeasured using an incremental borrowing rate at the date of modification of 9.26%, which resulted in an increase of the ROU asset of $147,000 and an increase in the operating lease liabilities of $159,000.

Based on the present value of the lease payments for the remaining lease term of the Company's existing operating leases, as of June 30, 2026, total ROU assets were approximately $311,000, and operating lease liabilities were approximately $319,000.

The Company currently maintains one finance lease for equipment. On April 1, 2024, the Company entered into a finance lease for laboratory equipment which expires in 2029. The Company's obligation to make finance lease payments are included in "Lease liability, current portion" and "Lease liability, non-current portion" on the Company's consolidated balance sheets. As of June 30, 2026 total finance lease liabilities were $122,000.
