#### 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’s leases do not include substantial variable payments based on index or rates. The Company’s lease agreements do not contain any significant residual value guarantees or material restrictive covenants.

### NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
<div align='center'>For the years ended December 31, 2023 and 2022</div>

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 on a collateralized basis with similar terms and payments, and in similar economic environments. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The lease payments related to the next 12 months are included in operating lease liabilities, current on the consolidated balance sheets. The Company recognizes a single lease cost on a straight-line basis over the term of the lease, and the Company classifies all cash payments within operating activities in the consolidated statements of cash flows.

The Company did not have any finance leases as of December 31, 2023 or 2022.

#### Intangible Assets
