On October 28, 2021, the Company entered into a lease for office and research and development space under a non-cancellable lease in Los Angeles, California (the “2021 Lease”). The 2021 Lease payment start date was May 1, 2022 and the total lease term is for 16 years and runs through 2038. Monthly rent for 2022 and 2023 was fully or partially abated while the lessor and the Company completed planned tenant improvements to the facility. The Company was responsible for construction costs over the tenant improvement allowance of $7.2 million. The construction was completed as of December 31, 2024, and the Company received the full allowance. Out-of-pocket expenses to be incurred by the Company are considered noncash lease payments, and included in the lease liability and right-of-use asset.

In connection with the execution of the 2021 Lease, the Company delivered an irrevocable standby letter of credit in the amount of $5.0 million to the landlord in 2022.

Impairment of ROU Asset

During the year ended December 31, 2025, an impairment charge of $5.4 million was recognized related to the Company’s office and research and development space under a non-cancelable operating lease in Marina del Rey, California. The impairment resulted from changes in the anticipated timeline in the Company’s plan to sublease the vacated space. The ROU asset was determined to be not fully recoverable as the estimated undiscounted cash flows expected from sublease income were insufficient to recover the ROU asset’s carrying amount. The impairment charge was determined using level 3 inputs measured based on an income approach, with unobservable inputs including the estimates and assumptions for sublease income and a discount rate commensurate with the remaining lease term of 21.6%. There was no impairment of long-lived assets during the year ended December 31, 2024.

Legal Proceedings

From time to time, the Company may be involved in disputes, including litigation, relating to claims arising out of operations in the normal course of business. Any of these claims could subject the Company to costly legal expenses and, while management generally believes that there is adequate insurance to cover many different types of liabilities, the Company’s insurance carriers may deny coverage or 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 the consolidated results of operations and financial position. Additionally, any such claims, whether or not successful, could damage the Company’s reputation and business. The Company is currently 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 its consolidated results of operations or financial position.
