 lease right-of-use (“ROU”) asset and lease liability are recognized based on the present value of lease payments over the lease term. While the operating leases may include options to extend the term, these options are not included when calculating the operating lease ROU asset and lease liability unless it is reasonably certain such options will be exercised. The Company uses the incremental borrowing rate to determine the present value of the future lease payments, which is the theoretical interest rate that the Company would pay to borrow under similar terms and payments on a collateralized basis for the lease. The Company applies the short-term lease measurement and recognition practical expedient to its leases with an initial term of 12 months or less, which are not recorded in the consolidated balance sheets. The Company’s lease agreements include both lease and non-lease components, such as common area maintenance, which are variable and are accounted for together with the lease as a single lease component.

#### Property, Software, and Equipment, Net
Property, software, and equipment are stated at cost, net of accumulated depreciation. Expenditures for repairs and maintenance are expensed in the period incurred. Property, software, and equipment, net is included in other noncurrent assets in the consolidated balance sheets. Depreciation is computed using the straight-line method based on estimated useful lives of the respective assets. Depreciation expense is included in the consolidated statements of operations, allocated to operations and support, product development, marketing, and general and administrative expenses based on relative payroll percentages by function.

The Company capitalizes expenses for developing and enhancing internal-use software once the preliminary project stage is complete, it is probable that the project will be completed and the software will be used to perform the function intended. Capitalized costs are amortized over the estimated useful life of the software on a straight-line basis. The useful life of all capitalized internally developed software as of January 31, 2024 and 2025 was three years. Capitalization ceases when the software project is substantially complete and ready for its intended use. The Company capitalizes personnel-related expenses for employees directly involved in the internal-use software development, limited to the time directly spent on the projects.
