Leases
The Company has entered into various operating lease agreements for office space, data center, lab and warehouse use, with remaining terms ranging from 0.3 to 7.5 years, some of which include one or more options to renew. As leases approach maturity, the Company considers various factors such as market conditions and the terms of any renewal options that may exist to determine whether it will renew the lease, as such, the Company does not include renewal options in its lease terms for calculating its lease liability, as the renewal options allow it to maintain operational flexibility and the Company is not reasonably certain it will exercise these renewal options at the time of the lease commencement.
In April 2025, the Company entered into a lease amendment for its office and lab space of approximately 163,000 square feet in Redwood City, California, the Redwood City lease, and extended the lease terms by additional 3.1 to 6.0 years to December 31, 2030, and December 31, 2031. The Company accounted for this amendment as a lease modification by remeasuring the ROU assets and lease liabilities as of the effective date, and recorded additional ROU assets and lease liabilities of $35.4 million, respectively. In addition, the Redwood City lease has been classified as an operating lease. The Company estimated the incremental borrowing rate of 7.98% to determine the present value of lease payments for the Redwood City lease using market yield curves based on similar terms and the Company's credit rating.
Operating lease expense for the years ended December 31, 2025, 2024 and 2023, was $33.6 million, $31.1 million and $29.7 million, respectively, which includes both lease and non-lease components (primarily common area maintenance charges and property taxes).

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.
