Certain matters discussed in this Quarterly Report on Form 10-Q contain “forward-looking statements” that are intended to be covered by the safe harbor for such statements provided by the Private Securities Litigation Reform Act of 1995. East West Bancorp, Inc. (referred to herein on an unconsolidated basis as “East West” and on a consolidated basis as the “Company,” “we,” “our” or “EWBC”) may make forward-looking statements in other documents that it files with, or furnishes to, the United States (“U.S.”) Securities and Exchange Commission (“SEC”) and management may make forward-looking statements to analysts, investors, media members and others. Forward-looking statements are those that do not relate to historical facts and that are based on current assumptions, beliefs, estimates, expectations and projections, many of which, by their nature, are inherently uncertain and beyond the Company’s control. Forward-looking statements may relate to various matters, including the Company’s financial condition, results of operations, plans, objectives, future performance, business or industry, and usually can be identified by the use of forward-looking words such as “anticipates,” “assumes,” “believes,” “can,” “continues,” “could,” “estimates,” “expects,” “forecasts,” “goal,” “intends,” “likely,” “may,” “might,” “objective,” “plans,” “potential,” “projects,” “remains,” “should,” “target,” “trend,” “will,” “would,” or similar expressions or variations thereof, and the negative thereof, but these terms are not the exclusive means of identifying such statements. You should not place undue reliance on forward-looking statements, as they are subject to known and unknown risks and uncertainties.

Factors that might cause future results to differ materially from historical performance and any forward-looking statements include, but are not limited to:

• changes in local, regional and global business, economic and political conditions, and natural or geopolitical events;
• the soundness of other financial institutions and the impacts related to or resulting from bank failures and other industry volatility, including potential increased regulatory requirements, Federal Deposit Insurance Corporation insurance premiums and assessments, and deposit withdrawals;
• changes in trade, tariff, tax, monetary and fiscal policies;
• changes in immigration laws and enforcement practices, or travel and visa related policies;
• current or potential disputes between the U.S., the People’s Republic of China, Singapore and other countries;
• changes in the commercial and consumer real estate markets;
• changes in consumer or commercial spending, savings and borrowing habits, and patterns and behaviors;
• the Company’s ability to compete effectively against financial institutions and other entities, including as a result of emerging technologies;
• the success and timing of the Company’s business strategies;
• the Company’s ability to retain key officers and employees;
• changes in interest rates, competition, regulatory requirements and product mix;
• changes in the Company’s costs of operation, compliance and expansion;
• disruption, failure in, or breach of, the Company’s operational or security systems or infrastructure, or those of third-party vendors with which the Company does business, including as a result of cyber-attacks, and the disclosure or misuse of confidential information;
• the adequacy of the Company’s risk management framework;
• future credit quality and performance, including expectations regarding future credit losses and allowance levels;
• adverse changes to the Company’s credit ratings;
• legal proceedings, regulatory investigations and their resolution;
• the Company’s capital requirements and its ability to generate capital internally or raise capital on favorable terms;
• the impact on the Company’s liquidity due to changes in the Company’s ability to receive dividends from its subsidiaries; and
• any strategic acquisitions or divestitures, the introduction of new or expanded products and services or other events that may directly or indirectly result in a negative impact on the financial performance of the Company and its customers.

For a more detailed discussion of some of the factors that might cause such differences, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 28, 2025 under the heading Item 1A. Risk Factors . You should treat forward-looking statements as speaking only as of the date they are made and based only on information then actually known to the Company. The Company does not undertake, and specifically disclaims any obligation to update or revise any forward-looking statements to reflect the occurrence of events or circumstances after the date of such statements except as required by law.

While the unaudited interim Consolidated Financial Statements reflect all adjustments that, in the opinion of management, are necessary for fair presentation, they primarily serve to update the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the U.S. SEC on February 28, 2025 (the “Company’s 2024 Form 10-K”), and may not include all the information and notes necessary to constitute a complete set of financial statements. Accordingly, they should be read in conjunction with the audited Consolidated Financial Statements and notes thereto included in the Company’s 2024 Form 10-K.

The preparation of the Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the Consolidated Financial Statements, income and expenses during the reporting periods, and the related disclosures. Although our estimates consider current conditions and how we expect them to change in the future, it is reasonably possible that actual results could be materially different from those estimates. Hence, the current period’s results of operations are not necessarily indicative of results that may be expected for any future interim period or for the year as a whole. Certain items on the Consolidated Financial Statements and notes for the prior periods have been reclassified to conform to the current presentation. Events subsequent to the Consolidated Balance Sheet date have been evaluated through the date the Consolidated Financial Statements are issued for inclusion in the accompanying Consolidated Financial Statements.

Significant Accounting Policies Update

Stock-Based Compensation — The Company recognizes compensation expense related to stock awards over the requisite service period, generally based on the instruments’ grant-date fair value, reduced by expected forfeitures. Effective third quarter 2025, compensation cost related to awards granted to employees who meet certain age plus years-of-service requirements (“retirement-eligible employees”) is accrued over the service period required to earn the award prior to the grant date, in accordance with ASC 718-10-55-108. This change in the timing of recognition for awards that were granted to or are expected to be granted to retirement-eligible employees resulted in $ 27 million of additional compensation expense during the three months ended September 30, 2025. For more information on the Company’s accounting policies related to stock-based compensation, see Note 1 — Summary of Significant Accounting Policies — Significant Accounting Policies — Stock-Based Compensation to the Consolidated Financial Statements of the Company’s 2024 Form 10-K.

Note 2 — Fair Value Measurement and Fair Value of Financial Instruments

Under applicable accounting standards, the Company measures a portion of its assets and liabilities at fair value. These assets and liabilities are predominantly recorded at fair value on a recurring basis. At times, certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, they are subject to fair value adjustments only as required through the application of an accounting method such as lower of cost or fair value or write-down of individual assets. The Company categorizes its assets and liabilities into three levels based on the established fair value hierarchy and conducts a review of fair value hierarchy classifications on a quarterly basis. For more information regarding the fair value hierarchy and how the Company measures fair value, see Note 1 — Summary of Significant Accounting Policies — Significant Accounting Policies — Fair Value to the Consolidated Financial Statements in the Company’s 2024 Form 10-K.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following section describes the valuation methodologies used by the Company to measure financial assets and liabilities on a recurring basis, as well as the general classification of these instruments within the fair value hierarchy.

Available-for-Sale Debt Securities — The fair value of AFS debt securities is generally determined by independent external pricing service providers who have experience in valuing these securities or by taking the average quoted market prices obtained from independent external brokers. The valuations provided by the third-party pricing service providers are based on observable market inputs, which include benchmark yields, reported trades, issuer spreads, benchmark securities, bids, offers, prepayment expectations and reference data obtained from market research publications. Inputs used by the third-party pricing service providers in valuing collateralized mortgage obligations and other securitization structures also include newly issued data, monthly payment information, whole loan collateral performance, tranche evaluation and “To Be Announced” prices. In valuing securities issued by state and political subdivisions, inputs used by third-party pricing service providers also include material event notices. The valuations provided by the brokers incorporate information from their trading desks, research and other market data.

On a monthly basis, the Company validates the valuations provided by third-party pricing service providers to ensure that the fair value determination is consistent with the applicable accounting guidance and that the financial instruments are properly classified in the fair value hierarchy. To perform this validation, the Company evaluates the fair values of securities by comparing the fair values provided by the third-party pricing service providers to prices from other available independent sources for the same securities. When significant variances in prices are identified, the Company further compares the inputs used by different sources to ascertain the reliability of these sources. On a quarterly basis, the Company reviews the valuation inputs and methodology furnished by third-party pricing service providers for each security category. On an annual basis, the Company assesses the reasonableness of broker pricing by reviewing the related pricing methodologies. This review includes corroborating pricing with market data, performing pricing input reviews under current market-related conditions, and investigating security pricing by instrument as needed.
