As of June 30, 2026, the Company had an operating lease with Kilroy Realty, L.P. (the "Landlord") for office space located in San Diego, California, which was entered into in April 2019 and subsequently amended in May 2020. Coinciding with the Company's ability to direct the use of the office space, which occurred in phases over 2020, and utilizing a discount rate equal to the Company's estimated incremental borrowing rate, the Company established right-of-use assets totaling $34.6 million and lease liabilities totaling $34.5 million. The total right-of-use asset and lease liability at measurement were each offset by lease incentives associated with tenant improvement allowances totaling $7.9 million.

The initial term of the office lease ends in August 2028, and the Landlord has granted the Company an option to extend the term of the lease by a period of five years. At lease inception, it was not reasonably certain that the Company will extend the term of the lease and therefore the renewal period has been

excluded from the aforementioned right-of-use asset and lease liability measurements. The measurement of the lease term occurs from the February 2021 occupancy date of the office space.

In November 2024, the Company entered into a sublease for a portion of the premises. The term of the sublease runs from January 2025 through August 2028. The Company’s sublease arrangement has been classified as an operating lease with sublease income recognized on a straight-line basis over the term of the sublease arrangement. To measure the Company’s periodic sublease income, the Company elected to use a practical expedient under ASC 842 to aggregate non-lease components with the related lease components because (i) the timing and pattern of transfer for the non-lease components and the related lease components are the same and (ii) the lease components, if accounted for separately, would be classified as an operating lease.

The following is a schedule of the future minimum rental commitments for the Company's operating lease reconciled to the lease liability and right-of-use asset as of June 30, 2026 (in thousands):
