8. Leases

The Company has operating leases for buildings, equipment and vehicles. Existing leases have remaining terms ranging from less than one year to approximately 5 years. Some leases contain options to extend the lease, usually for up to five years, along with termination options. The Company’s facility lease has an expiration date of April 30, 2030 and contains an option to extend the lease, for up to five years, along with termination options. The Company is utilizing one floor (19th floor) for its corporate operations with all expense for this floor included within selling, general and administrative expense on the Company’s consolidated statements of operations for the years ended December 31, 2024 and 2023.

In connection with the Merger, the Company assumed three leases for office and laboratory space, with lease terms of three to five years. One of the assumed leases expired on June 30, 2024 and has not been renewed. The remaining leases require monthly lease payments that may be subject to annual increases throughout the lease term. The remaining leases also include renewal options at the Company's election to renew or extend the leases for additional periods ranging from three to ten years.

As part of the Company’s restructuring plan discussed further in Note 17, in August 2022, the Company entered into an agreement to sublease approximately 25% of its corporate headquarters space (18th floor) in South San Francisco, California for a period of 39 months, which commenced in October 2022. The Company expects to recognize $4.8 million of sublease income over the lease term. As of December 31, 2024, 12 months were remaining on the sublease. The Company expects to recognize $1.6 million of sublease income over the remaining lease term. In addition, on February 28, 2023, the Company signed a second agreement to sublease an additional 25% of its corporate headquarters (21st floor) for a period of 77 months, which commenced on December 1, 2023. The Company expects to recognize additional sublease income of $9.1 million over the lease term. At December 31, 2024, $7.7 million of sublease income is expected to be recognized over the remaining 64 months of the lease term.

Rent expense, net of sublease income, is reported within restructuring and related charges for the year ended December 31, 2024, in the consolidated statements of operations. The Company has fully vacated and is in the process of potentially subleasing an additional floor (20th floor).

About Leases Disclosures

Lease disclosures under ASC 842 provide a comprehensive view of a company's leased asset portfolio, including the split between operating and finance leases, discount rates used to present-value future payments, and the maturity schedule of lease obligations. This section reveals a significant source of off-balance-sheet commitments that were largely hidden before the current standard.

Key signals: the weighted-average discount rate affects the size of recorded lease liabilities — a higher rate reduces the reported obligation, so compare the chosen rate against the company's incremental borrowing rate. The operating versus finance lease mix affects both EBITDA and operating income presentation. Watch the maturity table for concentration risk: large payment cliffs in specific years may create cash flow pressure. Variable lease payments excluded from the liability measurement represent real obligations that do not appear on the balance sheet. Compare total lease costs against prior-year operating lease expense to assess the true economic burden.
