HANMI FINANCIAL CORP

We have established various accounting policies that govern the application of GAAP in the preparation of our financial statements. Our significant accounting policies are described in the Notes to the consolidated financial statements in the 2025 Annual Report on Form 10-K. We had no significant changes in our accounting policies since the filing of the 2025 Annual Report on Form 10-K.

Certain accounting policies require us to make significant estimates and assumptions that have a material impact on the carrying value of certain assets and liabilities, and we consider these to be critical accounting policies. For a description of these critical accounting policies, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies” in the 2025 Annual Report on Form 10-K. Actual results could differ significantly from these estimates and assumptions, which could have a material impact on the carrying value of assets and liabilities at the balance sheet dates and our results of operations for the reporting periods. Management has discussed the development and selection of these critical accounting policies with the Audit Committee of the Company’s Board of Directors.
