The Company’s operating lease for its headquarters facility office space in Redwood City, California began in June 2021 and expired in May 2023. In April 2023, the Company entered into a twenty-four month lease extension commencing on June 1, 2023. The term of the lease extension expires in May 2025. On February 8, 2024, the Company entered into a six-month office license agreement to license 4,141 square feet of additional space adjacent to its existing office where the Company is currently located. The term for the additional space expires on October 31, 2024, unless terminated earlier in accordance with the license agreement. In July 2024, the Company provided notice of early termination of the license agreement for the additional space effective September 17, 2024.

On June 13, 2024, the Company entered into a new office lease in Redwood City, California for office space for its headquarters facility. The lease provides office space of approximately 18,026 square feet and for base monthly rent payments beginning at $57,400 that increase annually by approximately 3.0% over the term of five years from the date of occupancy. In addition to base rent, the Company has agreed to reimburse the landlord for certain operating expenses under the terms of the lease. The lease commencement date is September 1, 2024 when the premises will be available for occupancy and therefore as the office lease has not commenced, the related operating lease ROU assets and liabilities are not recorded in the Company's condensed consolidated balance sheet as of June 30, 2024.

The Company's operating lease ROU assets, current operating lease liabilities and long-term operating lease liabilities each appear as a separate line within the Company's condensed consolidated balance sheet. As of June 30, 2024 and December 31, 2023, the Company's short-term liabilities were equal to $0.3 million and $0.3 million, respectively, and the long-term operating lease liabilities were equal to zero and $0.1 million, respectively. Due to the short-term nature of the February 2024 office license agreement, the license agreement obligations are not included in the Company's right-of-use assets and lease liabilities on the Company's condensed consolidated balance sheet.

In 2023, the Company recorded an increase to its right-of-use asset by $0.6 million and an increase to its lease liability by $0.6 million as a result of the 2023 lease extension. The weighted average discount rate related to the Company's lease liabilities as of June 30, 2024 was 8.25% over a remaining term of 11 months. The weighted average discount rate related to the Company's lease liabilities as of December 31, 2023 was 8.25% over a remaining term of 17 months. The discount rate was determined based on estimates of the Company’s incremental borrowing rate, as the discount rate implicit in the lease cannot be readily determined.

In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnifications. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future but have not yet been made. The Company accrues a liability for such matters when it is probable that future expenditures will be made, and such expenditures can be reasonably estimated.
