’s leases do not provide an implicit rate, the Company uses its incremental
borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Company calculates the associated lease liability and corresponding ROU asset upon lease commencement using a discount
rate based on a credit-adjusted secured borrowing rate commensurate with the term of the lease. As of December 31, 2024, the Company has no finance leases.

In April 2023, the Company modified the lease term for its principal executive offices located in Palo Alto, California. The modification extended the lease
term for an additional three years, with the lease term expiring in September 2027. As a result of the modification, the Company recognized additional ROU assets and corresponding lease liabilities of $2.5 million.

Lease expense was $1.0 million and $1.1 million for the years ended December 31, 2024 and 2023, respectively, and was primarily comprised of
operating lease costs. The lease expense also included variable lease costs and sublease income, which were immaterial for the periods presented.
