### Notes to Consolidated Financial Statements

#### Accounts Receivable
Accounts receivable are carried at the amount due. Accounts receivable are written off when management deems all realistic efforts to collect the amount outstanding have been exhausted. A provision for credit losses is estimated by management based on evaluations of its historical bad debt and current collection experience. As of December 31, 2024 and 2023, an allowance for credit losses was not required. Write-offs of accounts receivable were not significant during the years ended December 31, 2024 and 2023.

#### Inventory
Inventory is stated at the lower of cost or net realizable value. Cost is determined using the weighted-average cost method. The Company periodically reviews the value of items in inventory and provides write-offs of inventory that is obsolete. Appropriate consideration is given to obsolescence, excessive levels, deterioration, and other factors in evaluating net realizable value. Once inventory has been written down below cost, it is not subsequently written up.

#### Property and Equipment, Net
Property and equipment, net are recorded at cost, less accumulated depreciation. Expenditures for major additions and improvements are capitalized and minor replacements, maintenance, and repairs are charged to current operations as incurred. When property and equipment are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations for the respective period. Depreciation is provided over the estimated useful lives of the related assets using the straight-line method. Leasehold improvements are amortized over the lesser of the term of the related lease or the estimated useful lives of the assets.

#### Leases
The Company primarily enters into leases for office space that are classified as operating leases. The Company determines if an arrangement is or contains a lease at inception. The Company accounts for leases by recording right-of-use (“ROU”) assets and lease liabilities on the consolidated balance sheets in the captions operating lease right-of-use assets, net and operating lease liabilities, respectively. The lease term includes the non-cancelable period of the lease plus any additional periods covered by an option to extend that the Company is reasonably certain to exercise. The Company’s leases do not include substantial variable payments based on an index or rates. The Company’s lease agreements do not contain any significant residual value guarantees or material restrictive covenants.

The Company’s leases do not provide a readily determinable implicit discount rate. The Company’s incremental borrowing rate is estimated to approximate the interest rate
