10.Leases

The Company leases approximately 27,532 square feet of office space for its corporate headquarters in Redwood City, California under a lease agreement that expires in September 2027. The Company also leases approximately 25,017 square feet for its laboratory facilities in Camarillo, California. This lease commenced in January 2020, terminates in May 2027 and contains a one-time option to extend the lease term for five years. Both facility leases provide for certain limited rent abatement and annual scheduled rent increases over their respective lease terms.

The Company determined that the above facility leases were operating leases. No options to extend the lease terms were included as part of the right-of-use assets or lease liabilities as it was not reasonably certain the Company would exercise those options.

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.
