Redwood City, California

The Company has a lease for facilities in Redwood City, California. Related to this lease, the Company provided the landlord with a letter of credit in the amount of $2.5 million, which is classified as restricted cash under long term assets on the Company's condensed consolidated balance sheets.

In March 2023, the Company entered into an amendment to accelerate the expiration of one of its Redwood City premises under the existing lease from December 31, 2031 to September 30, 2023. Concurrently, the Company entered into an agreement for additional tenant improvement allowance towards its other Redwood City premises. As a result of the modification the Company revalued the lease liability based on the new and remaining lease terms, which resulted in a reduction to the lease liability of $8.3 million, and recognized the remeasurement to the lease liabilities as an adjustment to the right-of-use asset. The estimated value of non-cash consideration, composed primarily of leasehold improvements and furniture and fixtures, was $14.9 million.

In April 2023, the Company entered into an amendment to reduce the rent payments for the NC Premises, which will be effective as of May 1, 2023.

On October 26, 2021, the Company entered into a sublease agreement with a subtenant for the NC Premises through October 2037, the remainder of the lease term. In line with the amendment to the NC Premises' lease, sublease rent payments were correspondingly reduced.
