HANMI FINANCIAL CORP

Note 1 — Organization and Basis of Presentation

Hanmi Financial Corporation (“Hanmi Financial,” the “Company,” “we,” “us” or “our”) is a bank holding company whose primary subsidiary is Hanmi Bank (the “Bank”). Our primary operations are related to traditional banking activities, including the acceptance of deposits and the lending and investing of money by the Bank.

In management’s opinion, the accompanying unaudited consolidated financial statements of Hanmi Financial and its subsidiaries reflect all adjustments of a normal and recurring nature that are necessary for a fair presentation of the results for the interim period ended March 31, 2025. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. The unaudited consolidated financial statements are prepared in conformity with GAAP and in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission. Operating results for the three-month periods ended March 31, 2025 are not necessarily indicative of the results that may be expected for the year ended December 31, 2025 or for any other period. The interim information should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2024 (the “2024 Annual Report on Form 10-K”).

The preparation of interim unaudited consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions affect the amounts reported in the unaudited financial statements and disclosures provided, and actual results could differ.

Descriptions of our significant accounting policies are included in Note 1-Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements in the 2024 Annual Report on Form 10-K.

Effective January 1, 2025, the Company changed its methodology for estimating expected credit losses on its loan portfolio in accordance with Accounting Standards Update ("ASU") 2016-23, Financial Instruments – Credit Losses. Previously, the Company primarily used a Probability of Default / Loss Given Default (PD/LGD) model to determine the allowance for credit losses. Following a periodic review of its credit loss estimation process, the Company concluded that a historical loss rate approach, adjusted for current conditions and reasonable and supportable forecasts, more appropriately reflects the expected credit losses for its loan portfolio. This change is considered a change in accounting estimate resulting from a change in methodology and assumptions, and is accounted for prospectively in accordance with ASC 250-10-45-17 through 45-18.

The change in methodology had an immaterial impact to the Company’s operating results and financial condition. The provision for credit losses for the quarter ended March 31, 2025 reflects this change in estimate. Management believes the revised approach enhances the accuracy and relevance of its allowance for credit losses by aligning the methodology more closely with the Company’s historical experience, the nature of its loan portfolio, and expectations for future economic conditions.
