Operating Leases

We currently have two operating leases for administrative and research and development office and lab space in San Diego, California and Boston, Massachusetts that expire between July 2031 and May 2033. Under the terms of the operating leases, as each may be amended from time to time, we are required to pay our proportionate share of property taxes, insurance and normal maintenance costs. Both of our leases include renewal options for an additional five years, which were not included in the determination of the ROU asset or lease liability as the renewal was not reasonably certain at the inception of the lease. Our Boston lease provided for $1.4 million in reimbursements for allowable tenant improvements and rent credits, which effectively reduced the total lease payments owed. Our San Diego research and development, lab, and principal executive office space lease entered into in January 2025 and amended in June 2025 provides (i) $2.4 million in rent credits, and (ii) a $6.2 million tenant improvement allowance expected to be received in the first half of 2026. The leases are also subject to additional variable charges for common area maintenance, property taxes, property insurance and other variable costs. Variable charges were not included in the measurement of our operating lease ROU assets.

As of December 31, 2025 and 2024, the weighted-average discount rate was 12.3% and 11.4%, respectively, and the weighted-average remaining lease term was 6.4 years and 5.9 years, respectively.

Total cash paid for amounts included in the measurement of operating lease liabilities, net of tenant improvement reimbursements, was $0.9 million, $1.5 million and $2.1 million for the years ended December 31, 2025, 2024 and 2023, respectively. Operating lease ROU assets obtained in exchange for operating lease liabilities were $2.7 million and $4.7 million for the years ended December 31, 2025 and 2023, respectively. There were no operating lease ROU assets obtained in exchange for operating liabilities for the years ended December 31, 2024.

Total operating lease expense and rent expense for the years ended December 31, 2025, 2024 and 2023 was approximately $3.1 million, $1.9 million and $2.0 million, respectively.

Litigation

From time to time, we may be involved in disputes, including litigation, relating to claims arising out of operations in the normal course of our business. Any of these claims could subject us to costly legal expenses and, while we generally believe that we have adequate insurance to cover many different types of liabilities, our insurance carriers may deny coverage or our policy limits may be inadequate to fully satisfy any damage awards or settlements. If this were to happen, the payment of any such awards could have a material adverse effect on our results of operations and financial position. Additionally, any such claims, whether or not successful, could damage our reputation and business. We currently are not a party to any legal proceedings, the adverse outcome of which, in management’s opinion, individually or in the aggregate, would have a material adverse effect on our results of operations or financial position.
