Depreciation and amortization expense related to property and equipment, inclusive of amortization expense associated with capitalized internal-use software development costs, was approximately $6.6 million and $4.8 million for the three months ended March 31, 2026 and 2025, respectively. On January 31, 2025, the Company amended the lease agreement for its corporate headquarters located in Boston, Massachusetts which, among other things, extended the term of the lease to March 2033. Under the Company’s accounting policy, the useful life of leasehold improvements is the lesser of the lease term and the useful life of the asset. As such, the extension of the lease represents a change in estimate of the useful life of the leasehold improvements within the corporate headquarters. The Company accounted for this change in the useful lives as a change in accounting estimate under ASC 250 Accounting Changes and Error Corrections, which were recorded prospectively upon execution of the lease amendment. This change in estimate resulted in a reduction of $1.2 million and $0.6 million in depreciation expense for the three months ended March 31, 2026 and 2025, respectively, and an immaterial impact on basic and diluted net loss per share attributable to Series A and Series B common stockholders.
