Noncancelable lease agreement description In January 2025, the Company entered into a lease amendment to its headquarters location lease (the “Headquarters Amendment”), pursuant to which the Company will relocate to a new office space located in the same building. In May 2025, the Company took possession of the new office space upon substantial completion of the landlord’s work. As of June 30, 2025, the remaining lease term of the new office space is 36 months. Monthly lease payments increased when the Company took possession of the new office space and will escalate through the lease term, resulting in an annualized payment of $0.6 million. The Company remains subject to additional charges for common area maintenance and other costs. The Company has one option to extend the lease for an additional term of three years, and the monthly payment amounts would be determined by the landlord at the then-prevailing rate.Upon entering into the Headquarters Amendment, the Company remeasured the right-of-use asset and lease liability pertaining to its current headquarters, and as a result recorded an additional $0.1 million to both its right-of-use asset and lease liability on its condensed consolidated balance sheet. Upon possession of the new office space, the Company recognized a right-of-use asset and lease liability of $1.6 million on its condensed consolidated balance sheet. As there was not an implicit rate within the lease amendment, a discount rate of 8% was determined using a set of peer companies’ incremental borrowing rates.     In October 2021, the Company entered into a 38-month noncancelable office space lease for its current headquarters location in San Diego, California. Under the terms of the agreement, there is no option to extend the lease, and the Company is subject to additional charges for common area maintenance and other costs.
