In this Quarterly Report on Form 10-Q, the term “Bancorp” refers to Cathay General Bancorp and the term “Bank” refers to Cathay Bank. The terms “Company,” “we,” “us,” and “our” refer to Bancorp and the Bank collectively.

The statements in this report include forward-looking statements within the meaning of the applicable provisions of the Private Securities Litigation Reform Act of 1995 regarding management’s beliefs, projections, and assumptions concerning future results and events. We intend such forward-looking statements to be covered by the safe harbor provision for forward-looking statements in these provisions. All statements other than statements of historical fact are “forward-looking statements” for purposes of federal and state securities laws, including statements about anticipated future operating and financial performance, financial position and liquidity, growth opportunities and growth rates, growth plans, acquisition and divestiture opportunities, business prospects, strategic alternatives, business strategies, financial expectations, regulatory and competitive outlook, loan and deposit growth, investment and expenditure plans, financing needs and availability, level of nonperforming assets, and other similar forecasts and statements of expectation and statements of assumptions underlying any of the foregoing.

2. Basis of Presentation and Summary of Significant Accounting Policies

The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the interim periods presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2025. For further information, refer to the audited Consolidated Financial Statements and Notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 28, 2025 (the “2024 Form 10-K”).

The preparation of the Consolidated Financial Statements in accordance with GAAP requires management of the Company to make estimates and judgments that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities at the date of the Consolidated Financial Statements. Actual results could differ from those estimates. The Company expects that the most significant estimate subject to change is the allowance for loan losses.

3. Other Accounting Standards Pending Adoption

In September 2025, ASU No. 2025-06, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software.” ASU 2025-06 simplifies and modernizes the accounting for internal-use software by removing prescriptive project stage guidance and introducing a new capitalization threshold. Under the revised standard, software development costs are capitalized when management authorizes and commits funding for the project and it is probable the software will be completed and used as intended. ASU 2025-06 will be effective in 2028. The Company is currently evaluating the impact of this guidance on it's Consolidated Financial Statements.

In November 2024, ASU No. 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, was issued. This ASU requires disaggregated disclosure of income statement expenses for public business entities. ASU 2024-03 requires new financial statement disclosures in tabular format, disaggregating information about prescribed categories underlying any relevant income statement expense caption. The prescribed categories include, among other things, employee compensation, depreciation, and intangible asset amortization. Additionally, entities must disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. ASU 2024-03 is effective for us, on a prospective basis, for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, though early adoption and retrospective application is permitted. ASU 2024-03 is not expected to have a significant impact on our financial statements.

In December 2023, ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” was issued. This ASU amends the disclosure requirements for income taxes, including the requirement for further disaggregation of the income tax rate reconciliation and income taxes paid disclosures. The amendments in this guidance are effective for annual periods beginning after December 15, 2024. These amendments should be applied prospectively, with the option to apply retrospectively. ASU 2023-09 is effective for us beginning after December 15, 2025, and is not expected to have a significant impact on our financial statements.

4. Cash, Cash Equivalents and Restricted Cash

The Company manages its cash and cash equivalents based upon the Company’s operating, investment, and financing activities. Cash and cash equivalents, for the purposes of reporting cash flows, consist of cash and due from banks, short-term investments, and interest-bearing deposits. Cash and due from banks include cash on hand, cash items in transit, cash due from the Federal Reserve Bank of San Francisco (“FRBSF”) and other financial institutions. Short-term investments and interest-bearing deposits include cash placed with other banks with original maturity of three months or less.

The Company had average excess balance with FRBSF of $1.10 billion as of September 30, 2025, and $1.05 billion as of December 31, 2024. As of September 30, 2025, and December 31, 2024, the Company had $16.5 million and $43.4 million, respectively, as cash margin that serves as collateral on deposits in a cash margin account for interest rate swaps.

As of December 31, 2024, the Company held $0.3 million in a restricted escrow account with a major bank for its alternative energy investments.

5. Earnings per Share

Basic earnings per share excludes dilution and is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per common share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock and resulted in the issuance of common stock that then shared in earnings. Restricted stock units (“RSUs”) with anti-dilutive effect were not included in the computation of diluted earnings per share. The following table sets forth earnings per common share calculations:

	*Three Months Ended September 30,*				*Nine Months Ended September 30,*
	*2025*		*2024*		*2025*		*2024*

6. Stock-Based Compensation

Pursuant to the Company’s 2005 Incentive Plan, as amended and restated, the Company may grant incentive stock options (employees only), non-statutory stock options, common stock awards, restricted stock, RSUs, stock appreciation rights and cash awards to non-employee directors and eligible employees.

RSUs are generally granted at no cost to the recipient. RSUs generally vest ratably over three years or cliff vest after one or three years of continued employment from the date of the grant. While a portion of RSUs may be time-vesting awards, others may vest subject to the attainment of specified performance goals and are referred to as “performance-based RSUs.” All RSUs are subject to forfeiture until vested.

Performance-based RSUs are granted at the target amount of awards. Based on the Company’s attainment of specified performance goals and consideration of market conditions, the number of shares that vest can be adjusted to a minimum of zero and to a maximum of 150% of the target. The amount of performance-based RSUs that are eligible to vest is determined at the end of each performance period and is then added together to determine the total number of performance shares that are eligible to vest. Performance-based RSUs generally cliff vest three years from the date of grant.

Compensation costs for the time-based awards are based on the quoted market price of the Company’s stock at the grant date. Compensation costs associated with performance-based RSUs are based on grant date fair value, which considers both market and performance conditions. Compensation costs of both time-based and performance-based awards are recognized on a straight-line basis from the grant date until the vesting date of each grant.

The Company recognized an unrealized net loss of $2.3 million for the nine months ended September 30, 2025, compared to an unrealized net loss of $6.2 million for the nine months ended September 30, 2024. The $3.9 million decrease in unrealized loss was due to an increase in fair value of equity investments with readily determinable fair values for the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024. Equity securities were $32.1 million and $34.4 million as of September 30, 2025, and December 31, 2024, respectively.

Allowance for Credit Losses

The AFS securities that were in an unrealized loss position at September 30, 2025, were evaluated to determine whether the decline in fair value below the amortized cost basis resulted from a credit loss or other factors. For a discussion of the factors and criteria the Company uses in analyzing securities for impairment related to credit losses, see Note 1 - Summary of Significant Accounting Policies - Allowance for Credit Losses on Available for Sale Securities to the Consolidated Financial Statements in the Company’s 2024 Form 10-K.

The Company concluded the unrealized losses were primarily attributed to yield curve movement, together with widened liquidity spreads and credit spreads. The issuers have not, to the Company’s knowledge, established any cause for default on these securities. The Company expects to recover the amortized cost basis of its securities and has no present intent to sell and will not be required to sell securities AFS that have declined below their cost before their anticipated recovery. Accordingly, no allowance for credit losses was recorded as of September 30, 2025, against these securities, and there was no provision for credit losses recognized for the three and nine months ended September 30, 2025.

AFS securities having a carrying value of $19.5 million and $17.8 million as of September 30, 2025, and December 31, 2024, respectively, were pledged to secure public deposits and other borrowings.

The Company also has loan clients in Hong Kong. The Company has no specific industry concentration, and generally its loans, when secured, are secured by real property or other collateral of the borrowers. The Company generally expects loans to be paid off from the operating profits of the borrowers, from refinancing by other lenders, or through sale by the borrowers of the secured collateral.

The Company has adopted ASU 2022-02, "Financial Instruments – Troubled Debt Restructurings ("TDR") and Vintage Disclosures". The Company has elected to apply the guidance prospectively and the practical expedient to exclude the accrued interest receivable balance from the disclosed amortized cost basis of loan modifications to debtors experiencing financial difficulty, consistent with our Allowance for Credit Losses ("ACL") approach discussed further below in this footnote.

Under this guidance on loan modifications made to borrowers experiencing financial difficulty, when a loan held for investment is modified and is considered to be a continuation of the original loan, the Company uses the post-modification contractual rate to derive the effective interest rate when using a discounted cash flow method to determine the allowance for credit loss.

The amendments in this guidance require that an entity evaluate whether the modification represents a new loan or a continuation of an existing loan.

The Company establishes a specific reserve for individually evaluated loans that do not share similar risk characteristics with the loans included in the quantitative baseline. These individually evaluated loans are removed from the pooling approach for the quantitative baseline, and include non-accrual loans, loan modifications made to borrowers experiencing financial difficulty, and other loans as deemed appropriate by management. The Company applies the loan refinancing and restructuring guidance provided in ASU 2022-02 to determine whether a modification made to a borrower results in a new loan or a continuation of an existing loan.

If economic conditions or other factors worsen relative to the assumptions the Company utilized, the expected loan losses will increase accordingly in future periods.

The following table presents the amortized cost of loans modified to borrowers experiencing financial difficulty disaggregated by class of financing receivable, type of concession granted and the financial effects of the modifications for the three and nine months ended September 30, 2025, and September 30, 2024, by loan class and modification type.

The Company considers a loan to be in payment default once it is 60 to 90 days contractually past due under the modified terms. The Company tracks the performance of modified loans.

There were no loans that received modifications within the twelve months preceding payment default that subsequently defaulted during the three and nine months ended September 30, 2025, and September 30, 2024.

A modified loan may become delinquent and may result in a payment default (generally 90 days past due) subsequent to modification.

The Company closely monitors the performance of modified loans to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts.

The following table presents the performance of loans that were modified in the twelve months ended September 30, 2025, and 2024.

Under the Company’s internal underwriting policy, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification in order to determine whether a borrower is experiencing financial difficulty.

As of September 30, 2025, there were no commitments to lend additional funds to borrowers experiencing financial difficulty and whose loans were modified.

As part of the on-going monitoring of the credit quality of our loan portfolio, the Company utilizes a risk grading matrix to assign a risk grade to each loan. Loans are risk rated based on analysis of the current state of the borrower’s credit quality. The analysis of credit quality includes a review of sources of repayment, the borrower’s current financial and liquidity status and other relevant information. The risk rating categories can be generally described by the following grouping for non-homogeneous loans:

●

Pass/Watch – These loans range from minimal credit risk to higher than average, but still acceptable, credit risk. The loans have sufficient sources of repayment to repay the loans in full, in accordance with all the terms and conditions and remain currently well protected by collateral values.

●

Special Mention – Borrower is fundamentally sound, and loan is currently protected but adverse trends are apparent that, if not corrected, may affect ability to repay. Primary source of loan repayment remains viable but there is increasing reliance on collateral or guarantor support.

●

Substandard – These loans are inadequately protected by current sound net worth, paying capacity, or collateral. Well-defined weaknesses exist that could jeopardize repayment of debt. Loss may not be imminent, but if weaknesses are not corrected, there is a good possibility of some loss.

●

Doubtful – The possibility of loss is extremely high, but due to identifiable and important pending events (which may strengthen the loan), a loss classification is deferred until the situation is better defined.

●

Loss – These loans are considered uncollectible and of such little value that to continue to carry the loan as an active asset is no longer warranted.

The following table summarizes the Company’s loans held for investment and current year-to-date gross write-offs as of September 30, 2025, and December 31, 2024, presented by loan portfolio segments, internal risk ratings and vintage year. The vintage year is the year of origination, renewal or major modification. Revolving Loans that are converted to term loans presented in the table below are excluded from the term loans by vintage year columns.
