Exhibits 95 GLOSSARY OF ACRONYMS 96 SIGNATURE 97 2 Forward-Looking Statements Certain matters discussed in this Quarterly Report on Form 10-Q contain “forward-looking statements” 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, although 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 and other countries; • armed conflict involving Iran or heightened geopolitical tensions in other regions, including resulting oil price volatility and energy and other supply disruptions; • changes in the commercial and consumer real estate markets; • changes in consumer or commercial spending, savings and borrowing habits, 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 market 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 its ability to receive dividends from subsidiaries; • any strategic acquisitions or divestitures; and • 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 future results to differ materially from historical performance and any forward-looking statements, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 27, 2026 under the heading Item 1A. Risk Factors and the Company’s subsequent filings with the SEC. Forward-looking statements speak only as of the date they are made and are based solely on information then actually known to the Company. The Company does not undertake, and expressly disclaims, any obligation to update or revise any forward-looking statements to reflect events or circumstances after the date of such statements, except as required by law. 3 PART I — FINANCIAL INFORMATION ITEM 1.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Note 1 — Basis of Presentation and Current Accounting Developments 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”) is a registered bank holding company that offers a full range of banking services to individuals and businesses through its subsidiary bank, East West Bank and its subsidiaries (“East West Bank” or the “Bank”). The unaudited interim Consolidated Financial Statements in this Quarterly Report on Form 10-Q (this “Form 10-Q”) include the accounts of East West, East West Bank and East West’s subsidiaries. All i ntercompany balances and transactions have been eliminated in consolidation. The unaudited interim Consolidated Financial Statements are presented in accordance with United States (“U.S.”) Generally Accepted Accounting Principles (“GAAP”), applicable guidelines prescribed by regulatory authorities and general practices in the banking industry. 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, 2025, filed with the U.S. SEC on February 27, 2026 (the “Company’s 2025 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 2025 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. Recent Accounting Pronouncements Yet to be Adopted Standard Required Date of Adoption Description Effect on Financial Statements Accounting Standards Update (“ASU”) No. 2025-09, Derivatives and Hedging (Topic 815) : Hedge Accounting Improvements January 1, 2027 Early adoption is permitted. ASU 2025-09 addresses five specific matters: 1. Broadens the set of hedged risk that may be combined within a group of individual forecasted transactions in a cash flow hedge. 2. Enables entities to apply cash flow hedge accounting on “choose-your-rate” debt. 3. Broadens situations where hedge accounting can be applied to forecasted purchases and sales of nonfinancial assets. 4. Removes the requirement to perform net written option assessment for a compound derivative when it is designated as a hedging instrument. 5. In the case of a dual hedge where a foreign-currency-denominated debt instrument is designated as the hedging instrument in a net investment hedge and a hedged item in a fair value of interest rate risk, the ASU requires the debt instruments’ fair value-hedge basis adjustment be excluded when performing the net investment hedge effectiveness assessment. This guidance must be applied prospectively for all hedging relationships. The Company does not expect adoption to have a material impact on the Company’s Consolidated Financial Statements. 10 Recent Accounting Pronouncements Yet to be Adopted (Continued) Standard Required Date of Adoption Description Effect on Financial Statements ASU No. 2025-08, Financial Instruments—Credit Losses (Topic 326) January 1, 2027 Early adoption is permitted. ASU 2025-08 broadens the population of financial assets that are within scope of the gross up approach under Accounting Standards Codification (“ASC”) 326 to include purchased seasoned loans which are defined as: • Non-Purchased Credit Deteriorated (“PCD”) loans that are obtained in a business combination. • Non-PCD loans that are (1) obtained in an asset acquisition or upon consolidation of a VIE that is not a business and (2) are acquired more than 90 days after their origination date by a transferee that was not involved in their origination. The guidance also introduces an accounting policy election to use the amortized cost basis of the asset rather than the discounted cash flow analysis to subsequently measure the credit losses on purchased seasoned loans. The new guidance is not applicable to credit card loans, ASC 606 receivables, or debt securities. The guidance must be applied prospectively. The Company does not expect adoption to have a material impact on the Company’s Consolidated Financial Statements. ASU No. 2024-03, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40): D isaggregation of Income Statement Expenses December 31, 2027 Early adoption is permitted. ASU 2024-03 requires public companies to disclose, in interim and annual reporting periods, additional information about certain expenses in the notes to financial statements. Disclosures of disaggregated expenses include the following: • The amounts of (a) purchases of inventory; (b) employee compensation; (c) depreciation; (d) intangible asset amortization; and (e) depreciation, depletion and amortization of capitalized costs related to oil- and gas-producing activities in each relevant expense caption. • A qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. The Company does not expect adoption to have a material impact on the Company’s Consolidated Financial Statements. 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 2025 Form 10-K. Assets and Liabilities Measured at Fair Value on a Recurring Basis For additional information regarding the valuation methodologies used for the Company’s assets and liabilities measured at fair value on a recurring basis, as well as their general classification within the fair value hierarchy, see Note 2 — Fair Value Measurement and Fair Value of Financial Instruments to the Consolidated Financial Statements in the Company’s 2025 Form 10-K. 11 The following tables present financial assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2026 and December 31,

Nonrecurring fair value adjustments may result from the impairment on certain individually evaluated loans held-for-investment and affordable housing partnership, tax credit and CRA investments, from the write-downs of OREO and other nonperforming assets, or from the application of lower of cost or fair value on loans held-for-sale. Loans Held-for-Sale — Loans held-for-investment subsequently transferred to held-for-sale are recorded at the lower of cost or fair value upon transfer. Loans held-for-sale may be measured at fair value on a nonrecurring basis when fair value is less than cost. Fair value is generally determined based on available market data for similar loans and therefore, loans held-for-sale are classified as Level 2. For additional information regarding the valuation methodologies used for the Company’s assets and liabilities measured at fair value on a nonrecurring basis, as well as their general classification within the fair value hierarchy, see Note 2 — Fair Value Measurement and Fair Value of Financial Instruments to the Consolidated Financial Statements in the Company’s 2025 Form 10-K.

The Company manages credit exposure from certain transactions by entering into master netting agreements and collateral arrangements with the counterparties. The relevant agreements allow for an efficient closeout of the transaction, liquidation and set-off of collateral against the net amount owed by the counterparty following a default. It is the Company’s policy to take possession, where possible, of the assets underlying resale agreements. As a result of the Company’s credit risk mitigation practices with respect to resale agreements as described above, the Company did not hold any reserves for credit impairment with respect to these agreements as of both March 31, 2026 and December 31, 2025. There were no repurchase agreements as of December 31, 2025. Balance Sheet Offsetting The Company’s resale and repurchase agreements are transacted under legally enforceable master netting agreements that, in the event of default by the counterparty, provide the Company with the right to liquidate securities held and to offset receivables and payables with the same counterparty. The Company nets resale and repurchase transactions with the same counterparty on the Consolidated Balance Sheet when it has a legally enforceable master netting agreement and the transactions are eligible for netting under ASC 210-20-45-11, Balance Sheet Offsetting Repurchase and Reverse Repurchase Agreements . Collateral received includes securities that are not recognized on the Consolidated Balance Sheet. Collateral pledged consists of securities that are not netted on the Consolidated Balance Sheet against the related collateralized liability. Securities received or pledged as collateral in resale and repurchase agreements with other financial institutions may also be sold or re-pledged by the secured party, and are usually delivered to and held by third-party trustees. For more information regarding the Company’s accounting policy related to resale and repurchase agreement, see Note 1 — Summary of Significant Accounting Policies — Significant Accounting Policies — Assets Purchased under Resale Agreements and Securities Sold under Repurchase Agreements to the Consolidated Financial Statements in the Company’s 2025 Form 10-K.

In comparison, as of December 31, 2025, the Company had 429 AFS debt securities in a gross unrealized loss position, primarily consisting of 222 U.S. government agency and U.S. government-sponsored enterprise mortgage-backed securities, 47 corporate debt securities and 66 non-agency mortgage-backed securities. Allowance for Credit Losses on Available-for-Sale Debt Securities The Company evaluates each AFS debt security where the fair value declines below amortized cost. 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 — Significant Accounting Policies — Allowance for Credit Losses on Available-for-Sale Debt Securities to the Consolidated Financial Statements in the Company’s 2025 Form 10-K. The gross unrealized losses presented in the preceding tables were primarily attributable to interest rate movement and the widening of liquidity and/or credit spreads. U.S. Treasury, U.S. government agency, U.S. government-sponsored agency, and U.S. government-sponsored enterprise debt and mortgage-backed securities are issued, guaranteed, or otherwise supported by the U.S. government and have a zero credit loss assumption. The remaining securities that were in an unrealized loss position as of March 31, 2026 were mainly comprised of the following: • Corporate debt securities — The market value movement as of March 31, 2026 was primarily due to interest rate movement and spread change. A portion of the corporate debt securities is comprised of subordinated debt securities issued by U.S. banks. These securities are nearly all rated investment grade by nationally recognized statistical rating organizations (“NRSROs”) and issued by well-capitalized financial institutions with strong profitability. The contractual payments from these corporate debt securities have been and are expected to be received on time. The Company will continue to monitor the market developments in the banking sector and the credit performance of these securities. • Non-agency mortgage-backed securities — The market value movement for the majority of these securities as of March 31, 2026 was primarily due to interest rate movement and spread change. A substantial majority of the non-agency mortgage-backed securities are rated investment grade by NRSROs or have high priority in the cash flow waterfall within the securitization structure, and the contractual payments have historically been on time. Accordingly, the Company believes the risk of credit losses on these securities is low. As of both March 31, 2026 and December 31, 2025, the Company intended to hold the AFS debt securities with unrealized losses through the anticipated recovery period and it was more-likely-than-not that the Company would not have to sell these securities before the recovery of their amortized cost. The issuers of these securities have not, to the Company’s knowledge, established any cause for default on these securities. As a result, the Company expects to recover the entire amortized cost basis of these securities. There was no allowance for credit losses recorded against these securities as of March 31, 2026, compared with an allowance for credit losses of $ 2 million as of December 31, 2025, related to a non-agency commercial mortgage-backed security that experienced a deterioration in both its credit rating and expected cash flows, resulting in its fair value falling below amortized cost. A $ 192 thousand reversal of credit losses was recognized for the three months ended March 31, 2026, as a result of the sale of this security, compared with no provision for credit losses for the three months ended March 31, 2025 Allowance for Credit Losses on Held-to-Maturity Debt Securities The Company separately evaluates its HTM debt securities for any credit losses using an expected loss model, similar to the methodology used for loans. For additional information on the Company’s credit loss methodology, refer to Note 1 — Summary of Significant Accounting Policies — Significant Accounting Policies — Allowance for Credit Losses on Held-to-Maturity Debt Securities to the Consolidated Financial Statements in the Company’s 2025 Form 10-K. 23 The Company monitors the credit quality of the HTM debt securities using external credit ratings. As of March 31, 2026, all HTM securities were rated investment grade by NRSROs and issued, guaranteed, or supported by U.S. government entities and agencies. Accordingly, the Company applied a zero credit loss assumption and no allowance for credit losses was recorded as of both March 31, 2026 and December 31, 2025. Overall, the Company believes that the credit support levels of the debt securities are strong and based on current assessments and macroeconomic forecasts, expects that full contractual cash flows will be received.

The Company’s goal is to manage interest rate sensitivity and volatility to mitigate the effect of interest rate changes on earnings or capital. The Company may also use foreign exchange contracts to manage the foreign exchange rate risk associated with certain foreign currency-denominated assets and liabilities, the funding needs of, as well as the Bank’s investment in, East West Bank (China) Limited. The Company recognizes all derivatives on the Consolidated Balance Sheet at fair value. While the Company designates certain derivatives as hedging instruments in a qualifying hedge accounting relationship, other derivatives serve as economic hedges. For additional information on the Company’s derivatives and hedging activities, see Note 1 — Summary of Significant Accounting Policies — Significant Accounting Policies — Derivatives to the Consolidated Financial Statements of the Company’s 2025 Form 10-K. The following table presents the notional amounts and fair values of the Company’s derivatives as of March 31, 2026 and December 31, 2025. Certain derivative contracts are cleared through central clearing organizations where variation margin is applied daily as settlement to the fair values of the contracts. The fair values are presented on a gross basis prior to the application of bilateral collateral and master netting agreements, but after the application of variation margin payments as settlement to fair values of contracts cleared through central clearing organizations. Applying variation margin payments as settlement to the fair values of derivative contracts cleared through the London Clearing House (“LCH”) and the Chicago Mercantile Exchange (“CME”) resulted in reductions in the derivative asset and liability fair values of $ 14 million and $ 34 million, respectively, as of March 31, 2026. In comparison, applying variation margin payments as settlement to LCH- and CME-cleared derivative transactions resulted in reductions in the derivative asset and liability fair values of $ 16 million and $ 3 million, respectively, as of December 31, 2025. Total gross derivative asset and liability fair values are then adjusted to reflect the effects of legally enforceable master netting agreements and cash collateral received or paid. The resulting net derivative asset and liability fair values are included in Other assets and Accrued expenses and other liabilities , respectively, on the Consolidated Balance Sheet.

(3) The Company held warrant equity contracts in nine private companies as of both March 31, 2026 and December 31, 2025. (4) Equity contracts classified as derivative liabilities consist of 349  thousand performance-based RSUs granted as part of EWBC’s consideration in an investment. 27 Derivatives Designated as Hedging Instruments Cash Flow Hedges — The Company uses interest rate swaps and collars to hedge the variability in the interest amount received on certain floating-rate commercial loans due to changes in the contractually specified interest rates. As of March 31, 2026, interest rate contracts in notional amounts of $ 4.3  billion were designated as cash flow hedges to convert certain variable-rate loans from floating-rate payments to fixed-rate payments. Gains and losses on the hedging derivative instruments are recognized in AOCI and reclassified to earnings in the same period the hedged cash flows impact earnings and are recorded within the same income statement line item as the hedged cash flows. Considering the interest rates, yield curve and notional amount as of March 31, 2026, the Company expects to reclassify an estimated $ 2  million of after-tax net gains on derivative instruments designated as cash flow hedges from AOCI into earnings during the next 12 months. The following table presents the pre-tax changes in AOCI from cash flow hedges for the three months ended March 31, 2026 and 2025.

The Company also utilizes foreign exchange contracts to mitigate the effect of currency fluctuations on certain foreign currency-denominated on-balance sheet assets and liabilities, primarily foreign currency denominated deposits that it offers to its customers, as well as to meet its funding needs in certain foreign currencies. A majority of the foreign exchange contracts had original maturities of one year or less as of both March 31, 2026 and December 31, 2025. 28 The following table presents the notional amounts and the gross fair values of interest rate and foreign exchange derivatives entered into with customers and with third-party financial institutions, which serve as economic hedges to customers’ positions, as of March 31, 2026 and December 31, 2025: March 31, 2026 December 31, 2025 Fair Value Fair Value ($ in thousands) Notional Amount Assets Liabilities Notional Amount Assets Liabilities Customer-related positions: Interest rate contracts: Swaps $ 7,535,710   $ 29,626   $ 209,641   $ 7,566,889   $ 47,448   $ 206,794   Written options 1,298,056   —   3,093   1,463,110   —   1,900   Collars and corridors 340,632   53   312   444,604   311   20   Subtotal 9,174,398   29,679   213,046   9,474,603   47,759   208,714   Foreign exchange contracts: Forwards and spot 1,322,892   21,382   9,419   1,156,203   23,661   2,831   Swaps 831,485   9,187   5,435   785,956   13,272   661   Written options 64,561   —   2,276   63,460   —   73   Subtotal 2,218,938   30,569   17,130   2,005,619   36,933   3,565   Total $ 11,393,336   $ 60,248   $ 230,176   $ 11,480,222   $ 84,692   $ 212,279   Economic hedges and other: Interest rate contracts: Swaps $ 7,573,642   $ 212,016   $ 30,074   $ 7,604,959   $ 208,860   $ 47,682   Purchased options 1,298,056   3,130   —   1,463,110   1,922   —   Collars and corridors 340,632   312   58   444,605   20   335   Subtotal 9,212,330   215,458   30,132   9,512,674   210,802   48,017   Foreign exchange contracts: Forwards and spot 236,106   3,863   4,712   234,278   1,602   3,498   Swaps 2,637,352   18,893   28,147   2,246,744   5,718   36,083   Purchased options 64,561   2,278   2   63,460   87   14   Subtotal 2,938,019   25,034   32,861   2,544,482   7,407   39,595   Total $ 12,150,349   $ 240,492   $ 62,993   $ 12,057,156   $ 218,209   $ 87,612   29 The Company enters into energy commodity contracts with its customers in the oil and gas sector, which allow them to hedge against the risk of fluctuation in energy commodity prices.

Under the RPAs, a portion of the credit exposure is transferred from one party (the purchaser of credit protection) to another party (the seller of credit protection). The seller of credit protection is required to make payments to the purchaser of credit protection if the underlying borrower defaults on the related interest rate contract. The Company may enter into protection sold or protection purchased RPAs. Credit risk on RPAs is managed by monitoring the credit worthiness of the borrowers and the institutional counterparties, which is a part of the Company’s normal credit review and monitoring process. Assuming the underlying borrowers referenced in the interest rate contracts defaulted, the maximum exposure in the credit protection sold RPAs would be $ 584 thousand and $ 590 thousand as of March 31, 2026 and December 31, 2025, respectively. 30 The following table presents the notional amounts and the gross fair values of RPAs sold and purchased outstanding as of March 31, 2026 and December 31, 2025: March 31, 2026 December 31, 2025 Notional Amount Fair Value Notional Amount Fair Value ($ in thousands) Assets Liabilities Assets Liabilities RPAs — protection sold (1) $ 178,620   $ —   $ 129   $ 133,756   $ —   $ 51   RPAs — protection purchased 169,624   16   —   169,665   25   —   Total RPAs $ 348,244   $ 16   $ 129   $ 303,421   $ 25   $ 51   (1) All reference entities of the protection sold RPAs were investment grade.

Equity Contracts — As part of the loan origination process, the Company may obtain warrants to purchase the preferred and/or common stock of its borrowers’ companies, which are mainly in the technology and life sciences sectors. Warrants grant the Company the right to buy a certain class of the underlying company’s equity at a certain price before expiration. In connection with an investment the Company made during the third quarter of 2023, the Company granted performance-based RSUs as part of its consideration. The vesting of these equity contracts is contingent on the investee meeting certain financial performance targets during the future performance period. For additional information on these equity contracts, refer to Note 2 — Fair Value Measurement and Fair Value of Financial Instruments to the Consolidated Financial Statements in this Form 10-Q. The following table presents the net gains (losses) due to fair value changes that are recognized on the Company’s Consolidated Statement of Income related to derivatives not designated as hedging instruments for the three months ended March 31, 2026 and 2025: Three Months Ended March 31, ($ in thousands) Classification on Consolidated Statement of Income 2026 2025 Derivatives not designated as hedging instruments: Interest rate contracts Customer derivative income and derivative mark-to-market adjustments $ 1,247   $ ( 1,402 ) Credit contracts Customer derivative income and derivative mark-to-market adjustments ( 87 ) 10   Commodity contracts Customer derivative income and derivative mark-to-market adjustments ( 226 ) ( 78 ) Total derivative mark-to-market and credit valuation adjustments Customer derivative income and derivative mark-to-market adjustments 934   ( 1,470 ) Foreign exchange contracts Foreign exchange income 14,338   13,238   Equity contracts - warrants Lending and loan servicing fees 61   179   Equity contracts - performance-based RSU Other investment income 688   —   Net derivative gains $ 16,021   $ 11,947   Credit-Risk-Related Contingent Features — Certain of the Company’s over-the-counter derivative contracts contain early termination provisions that require the Company to settle any outstanding balances upon the occurrence of a specified credit-risk-related event. Such an event primarily relates to a downgrade of the credit rating of East West Bank to below investment grad e. As of March 31, 2026, the aggregate fair value amounts of all derivative instruments with credit risk-related contingent features that were in a net liability position totaled $ 4 million , for which $ 4 million collateral was posted to cover these positions. In comparison, a s of December 31, 2025, the aggregate fair value amounts of all derivative instruments with credit risk-related contingent features that were in a net liability position totaled $ 3 million, for which $ 3 million collateral was posted to cover these positions. In the event that the credit rating of East West Bank had been downgraded to below investment grade, the Company would have been required to post minimal additional collateral as of both March 31, 2026 and December 31, 2025. 31 Offsetting of Derivatives The following tables present the gross derivative fair values, the balance sheet netting adjustments, and the resulting net fair values recorded on the Consolidated Balance Sheet, as well as the cash and noncash collateral associated with master netting arrangements.

Accrued interest receivable on loans held-for-investment was $ 249 million and $ 251 million as of March 31, 2026 and December 31, 2025, respectively, and was included in Other assets on the Consolidated Balance Sheet. The interest income recognized and reversed on nonaccrual loans was immaterial for both the three months ended March 31, 2026 and 2025. For the Company’s accounting policy on accrued interest receivable related to loans held-for-investment, see Note 1 — Summary of Significant Accounting Policies — Significant Accounting Policies — Loans Held-for-Investment to the Consolidated Financial Statements of the Company’s 2025 Form 10-K. The Company also has loans held-for-sale. For the Company’s accounting policy on loans held-for-sale, refer to Note 1 — Summary of Significant Accounting Policies — Significant Accounting Policies — Loans Held-for-Sale to the Consolidated Financial Statements in the Company’s 2025 Form 10-K. The Company’s FRB and FHLB borrowings are primarily secured by loans held-for-investment. Loans held-for-investment totaling $ 42.8 billion and $ 41.8 billion were pledged to secure borrowings and provide additional borrowing capacity as of March 31, 2026 and December 31, 2025, respectively. Credit Quality Indicators All loans are subject to the Company’s credit review and monitoring process. For the commercial loan portfolio, loans are risk rated based on an analysis of the borrower’s current payment performance or delinquency, repayment sources, financial and liquidity factors, including industry and geographic considerations. For the consumer loan portfolio, payment performance or delinquency is typically the driving indicator for risk ratings. The Company utilizes internal credit risk ratings to assign each individual loan a risk rating of 1 through 10: • Pass — loans risk rated 1 through 5 are assigned an internal risk rating category of “Pass.” Loans risk rated 1 are typically loans fully secured by cash. Pass loans have sufficient sources of repayment to repay the loan in full, in accordance with all terms and conditions. • Special mention — loans assigned a risk rating of 6 have potential weaknesses that warrant closer attention by management; these are assigned an internal risk rating category of “Special Mention.” 33 • Substandard — loans assigned a risk rating of 7 or 8 have well-defined weaknesses that may jeopardize the full and timely repayment of the loan; these are assigned an internal risk rating category of “Substandard.” • Doubtful — loans assigned a risk rating of 9 have insufficient sources of repayment and a high probability of loss; these are assigned an internal risk rating category of “Doubtful.” • Loss — loans assigned a risk rating of 10 are uncollectible and of such little value that they are no longer considered bankable assets; these are assigned an internal risk rating category of “Loss.” Loan exposures categorized as criticized consist of special mention, substandard, doubtful and loss categories. The Company reviews the internal risk ratings of its loan portfolio on a regular basis, and adjusts the ratings based on changes in the borrowers’ financial status and the collectability of the loans. 34 The following tables summarize the Company’s loans held-for-investment and year-to-date gross write-offs by loan portfolio segments, internal risk ratings and vintage year as of the periods presented. The vintage year is the year of loan origination, renewal or major modification. Gross write-offs in the following tables are for the three months ended March 31, 2026, and the year ended December 31, 2025. Revolving loans that are converted to term loans presented in the tables below are excluded from the term loans by vintage year columns.

Assets acquired may include real properties (e.g., real estate, land, and buildings) and commercial and personal properties. The Company recognizes foreclosed assets upon receiving assets in satisfaction of a loan (e.g., taking legal title or physical possession). Foreclosed assets, consisting of OREO and other nonperforming assets, are included in Other assets on the Consolidated Balance Sheet. The Company had $ 15 million of foreclosed assets as of March 31, 2026, compared with $ 21  million as of December 31, 2025. The Company commences the foreclosure process on consumer mortgage loans after a borrower becomes more than 120 days delinquent in accordance with the Consumer Financial Protection Bureau guidelines. The carrying value of the consumer real estate loans that were in an active or suspended foreclosure process was $ 26 million and $ 16 million as of March 31, 2026 and December 31, 2025, respectively. Loan Modifications to Borrowers Experiencing Financial Difficulty As part of the Company’s loss mitigation efforts, the Company may agree to modify the contractual terms of a loan to assist borrowers experiencing financial difficulty. The Company negotiates loan modifications on a case-by-case basis to achieve mutually agreeable terms that maximize loan collectability and meet the borrower’s financial needs. The Company considers various factors to identify borrowers experiencing financial difficulty. The primary factor for consumer loan borrowers is delinquency status. For commercial loan borrowers, these factors include credit risk ratings, the probability of loan risk rating downgrades, and overall risk profile changes. The modification may include, but is not limited to, payment delays, interest rate reductions, term extensions, principal forgiveness, or a combination of such modifications. Commercial loan borrowers that require immaterial modifications such as insignificant interest rate changes, short-term extensions (90 days or less) from the original maturity date, or temporary waivers or extensions of financial covenants which would not constitute material credit actions, are generally not considered to be experiencing financial difficulty and are not included in the disclosure. Insignificant payment deferrals (three months or less in the last 12 months) are also not included in the disclosure. 40 The following tables present the amortized cost of loans that were modified during the three months ended March 31, 2026 and 2025 by loan class and modification type: Three Months Ended March 31, 2026 Modification Type ($ in thousands) Term Extension Payment Delay Combination: Term Extension/ Payment Delay Total Modification as a % of Loan Class Commercial: C&I $ 83,122   $ —   $ —   $ 83,122   0.43   % CRE 39,686   —   —   39,686   0.26   % Land and construction —   19,334   —   19,334   2.38   % Total commercial 122,808   19,334   —   142,142   0.35   % Consumer: SFR —   5,680   —   5,680   0.04   % HELOCs —   1,286   —   1,286   0.07   % Total consumer —   6,966   —   6,966   0.04   % Total $ 122,808   $ 26,300   $ —   $ 149,108   0.26   % Three Months Ended March 31, 2025 Modification Type ($ in thousands) Term Extension Payment Delay Combination: Term Extension/ Payment Delay Total Modification as a % of Loan Class Commercial: C&I $ 15,651   $ —   $ 23,749   $ 39,400   0.23   % CRE 18,082   —   —   18,082   0.12   % Multifamily 280   —   —   280   0.01   % Total commercial 34,013   —   23,749   57,762   0.15   % Consumer: SFR —   4,061   88   4,149   0.03   % HELOCs —   975   911   1,886   0.10   % Total consumer —   5,036   999   6,035   0.04   % Total $ 34,013   $ 5,036   $ 24,748   $ 63,797   0.12   % 41 The following table presents the financial effects of the loan modifications for the three months ended March 31, 2026 and 2025 by loan class and modification type: Financial Effects of Loan Modifications for the Three Months Ended March 31, 2026 2025 ($ in thousands) Weighted-average Term Extension (in years) Weighted-average Payment Delay (in years) Weighted-average Term Extension (in years) Weighted-average Payment Delay  (in years) Commercial: C&I 1.1 0.0 1.1 1.0 CRE 1.1 0.0 5.0 0.0 Land and construction 0.0 0.7 0.0 0.0 Consumer: SFR 0.0 0.5 10.0 1.0 HELOCs 0.0 1.1 17.6 15.4 A modified loan may become delinquent and may result in a payment default (generally 90 days past due) subsequent to modification.

Allowance for Credit Losses The Company has a current expected credit losses framework for all financial assets measured at amortized cost and certain off-balance sheet credit exposures. The Company’s allowance for credit losses, which includes both the ALLL and the allowance for unfunded credit commitments, is calculated with the objective of maintaining a reserve sufficient to absorb losses inherent in our credit portfolios. The measurement of the allowance for credit losses is based on management’s best estimate of lifetime expected credit losses, periodic evaluation of the loan portfolio, lending-related commitments and other relevant factors. The allowance for credit losses is deducted from the amortized cost basis of a financial asset or a group of financial assets so that the balance sheet reflects the net amount the Company expects to collect. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts, deferred fees and costs, and escrow advances. Subsequent changes in expected credit losses are recognized in net income as a provision for, or a reversal of, credit loss expense. 43 The allowance for credit losses estimation involves procedures to consider the unique risk characteristics of the portfolio segments. The majority of the Company’s credit exposures that share risk characteristics with other similar exposures are collectively evaluated. The collectively evaluated loans include performing loans and unfunded credit commitments. If an exposure does not share risk characteristics with other exposures, the Company generally estimates expected credit losses on an individual basis. ALLL for Collectively Evaluated Loans The allowance for collectively evaluated loans consists of a quantitative component that assesses the different risk factors considered in our models and a qualitative component that considers risk factors external to the models. These components are described below. Quantitative Component — The Company applies quantitative methods to estimate ALLL by considering a variety of factors such as historical loss experience, the current credit quality of the portfolio, and an economic outlook over the life of the loan. The Company incorporates forward-looking information using macroeconomic scenarios which include variables that are considered key drivers of increases and decreases in credit losses. The Company utilizes a probability-weighted, multiple-scenario forecast approach. These scenarios may consist of a base forecast representing management's view of the most likely outcome, combined with downside or upside scenarios reflecting possible worsening or improving economic conditions. The quantitative models incorporate a probability-weighted calculation of these macroeconomic scenarios over a reasonable and supportable forecast period. If the life of the loans extends beyond the reasonable and supportable forecast period, the Company will consider historical experience or long-run macroeconomic trends over the remaining life of the loans to estimate the ALLL. There were no changes to the reasonable and supportable forecast period, and no change to the reversion to the historical loss experience method for the three months ended March 31, 2026 and 2025. The following table provides key credit risk characteristics and macroeconomic variables that the Company uses to estimate the expected credit losses by portfolio segment: Portfolio Segment Risk Characteristics Macroeconomic Variables C&I Risk rating, sector, loan origination size, loan age, delinquency status Unemployment rate, gross domestic product (“GDP”), and U.S. Treasury rates CRE, Multifamily residential, and Construction and land Collateral value, property type, geographic location, loan age, delinquency status Unemployment rate, GDP, and U.S. Treasury rates SFR and HELOCs Collateral value, FICO score, geographic location, loan age, delinquency status House Price Indices, unemployment rate, GDP Other consumer Loss rate approach Immaterial — Macroeconomic variables are included in the qualitative estimate Quantitative Component — ALLL for the Commercial Loan Portfolio The Company’s C&I lifetime loss rate model estimates the loss rate expected over the life of a loan. This loss rate is applied to the amortized cost basis, excluding accrued interest receivable, to determine expected credit losses. The lifetime loss rate model’s reasonable and supportable period spans eight quarters, thereafter, immediately reverting to the historical average loss rate, expressed through the loan-level lifetime loss rate. To generate estimates of expected loss at the loan level for CRE, multifamily residential, and construction and land loans, projected probabilities of default (“PDs”) and loss given defaults (“LGDs”) are applied to the estimated exposure at default, considering the term and payment structure of the loan. The forecast of future economic conditions returns to long-run historical economic trends within the reasonable and supportable period. To estimate the life of a loan under both models, the contractual term of the loan is adjusted for estimated prepayments based on historical prepayment experience. 44 Quantitative Component — ALLL for the Consumer Loan Portfolio For SFR and HELOC loans, projected PDs and LGDs are applied to the estimated exposure at default, considering the term and payment structure of the loan, to generate estimates of expected loss at the loan level. The forecast of future economic conditions returns to long-run historical economic trends after the reasonable and supportable period. To estimate the life of a loan for the SFR and HELOC loan portfolios, the contractual term of the loan is adjusted for estimated prepayments based on historical prepayment experience. For other consumer loans, the Company uses a loss rate approach. Qualitative Component — The Company considers the following qualitative factors in the determination of the collectively evaluated allowance if these factors have not already been captured by the quantitative model. Such qualitative factors may include, but are not limited to: • loan growth trends; • the volume and severity of past due financial assets, and criticized or adversely classified financial assets; • the Company’s lending policies and procedures, including changes in lending strategies, underwriting standards, collection, write-off and recovery practices; • knowledge of a borrower’s operations; • the quality of the Company’s credit review system; • the experience, ability and depth of the Company’s management and associates; • the effect of other external factors such as the regulatory and legal environments, or changes in technology; • actual and expected changes in international, national, regional, and local economic and business conditions in which the Company operates; and • risk factors in certain industry sectors not captured by the quantitative models. The magnitude of the impact of these factors on the Company’s qualitative assessment of the allowance for credit losses changes from period to period according to changes made by management in its assessment of these factors. The extent to which these factors change may depend on whether they are already reflected in quantitative loss estimates during the current period and the extent to which changes in these factors diverge from period to period. While the Company’s allowance methodologies strive to reflect all relevant credit risk factors, there continues to be uncertainty associated with, but not limited to, potential imprecision in the estimation process due to the inherent time lag of obtaining information and normal variations between expected and actual outcomes. The Company may hold additional qualitative reserves that are designed to provide coverage for losses attributable to such risk. ALLL for Individually Evaluated Loans When a loan no longer shares similar risk characteristics with other loans, such as in the case of certain nonaccrual loans, the Company estimates the ALLL on an individual loan basis. The ALLL for individually evaluated loans is measured as the difference between the recorded value of the loans and their fair value. For loans evaluated individually, the Company uses one of three different asset valuation measurement methods: (1) the fair value of collateral less costs to sell; (2) the present value of expected future cash flows; or (3) the loan's observable market price. If an individually evaluated loan is determined to be collateral dependent, the Company applies the fair value of the collateral less costs to sell method. If an individually evaluated loan is determined not to be collateral dependent, the Company uses the present value of future cash flows or the observable market value of the loan. • Collateral-Dependent Loans — The allowance of a collateral-dependent loan is limited to the difference between the recorded value and fair value of the collateral less cost of disposal or sale. As of March 31, 2026, collateral-dependent commercial and consumer loans totaled $ 58 million and $ 17 million, respectively. In comparison, collateral-dependent commercial and consumer loans totaled $ 69 million and $ 10 million, respectively, as of December 31, 2025. The Company's collateral-dependent loans were secured by real estate. As of both March 31, 2026 and December 31, 2025, the collateral value of the properties securing the collateral-dependent loans, net of selling costs, exceeded the recorded value of the majority of the loans. 45 The following tables summarize the activity in the ALLL by portfolio segments for the three months ended March 31, 2026 and 2025: Three Months Ended March 31, 2026 Commercial Consumer CRE Residential Mortgage ($ in thousands) C&I CRE Multifamily Residential Construction and Land SFR HELOCs Other Consumer Total ALLL, beginning of period $ 475,613   $ 221,494   $ 36,555   $ 15,468   $ 53,463   $ 5,804   $ 1,376   $ 809,773   Provision for (reversal of) credit losses on loans (a) 17,892   11,160   2,880   2,593   3,519   92   ( 262 ) 37,874   Gross charge-offs ( 18,385 ) ( 1,305 ) —   ( 893 ) ( 121 ) —   ( 75 ) ( 20,779 ) Gross recoveries 7,918   453   11   2   22   3   251   8,660   Total net (charge-offs) recoveries ( 10,467 ) ( 852 ) 11   ( 891 ) ( 99 ) 3   176   ( 12,119 ) Foreign currency translation adjustment 346   —   —   —   —   —   —   346   ALLL, end of period $ 483,384   $ 231,802   $ 39,446   $ 17,170   $ 56,883   $ 5,899   $ 1,290   $ 835,874   Three Months Ended March 31, 2025 Commercial Consumer CRE Residential Mortgage ($ in thousands) C&I CRE Multifamily Residential Construction and Land SFR HELOCs Other Consumer Total ALLL, beginning of period $ 384,319   $ 218,677   $ 32,117   $ 17,497   $ 44,816   $ 3,132   $ 1,494   $ 702,052   Provision for (reversal of) credit losses on loans (a) 36,370   8,105   201   ( 305 ) 2,072   1,739   ( 120 ) 48,062   Gross charge-offs ( 988 ) ( 13,937 ) ( 4 ) ( 1,996 ) ( 9 ) —   ( 49 ) ( 16,983 ) Gross recoveries 1,564   54   10   3   50   8   13   1,702   Total net recoveries (charge-offs) 576   ( 13,883 ) 6   ( 1,993 ) 41   8   ( 36 ) ( 15,281 ) Foreign currency translation adjustment 23   —   —   —   —   —   —   23   ALLL, end of period $ 421,288   $ 212,899   $ 32,324   $ 15,199   $ 46,929   $ 4,879   $ 1,338   $ 734,856   In addition to the ALLL, the Company maintains an allowance for unfunded credit commitments. The Company has three general areas for which it provides the allowance for unfunded credit commitments: (1) recourse obligations for loans sold, (2) letters of credit, and (3) unfunded lending commitments. The allowance for unfunded credit commitments is maintained at a level that management believes to be sufficient to absorb estimated expected credit losses related to unfunded credit facilities. See Note 9 — Commitments and Contingencies to the Consolidated Financial Statements in this Form 10-Q for additional information related to unfunded credit commitments. The following table summarizes the activity in the allowance for unfunded credit commitments for the three months ended March 31, 2026 and 2025: Three Months Ended March 31, ($ in thousands) 2026 2025 Unfunded credit facilities Allowance for unfunded credit commitments, beginning of period $ 48,690   $ 39,526   (Reversal of) provision for credit losses on unfunded credit commitments (b) ( 1,682 ) 938   Foreign currency translation adjustments ( 3 ) —   Allowance for unfunded credit commitments, end of period $ 47,005   $ 40,464   Provision for credit losses on loans, leases and unfunded credit commitments (a) + (b) $ 36,192   $ 49,000   46 The allowance for credit losses on loans, leases and unfunded credit commitments was $ 883 million as of March 31, 2026, an increase of $ 25  million, compared with $ 858 million as of December 31, 2025. The increase in the allowance for credit losses was primarily driven by the Company’s net loan growth, qualitative risk assessment, and an economic outlook that reflected continued caution regarding inflation, the high-interest rate environment, and rising oil prices as a result of the Middle East conflict. The Company considers multiple economic scenarios to develop the estimate of the ALLL. The scenarios may consist of a baseline forecast representing management's view of the most likely outcome, and downside or upside scenarios that reflect possible worsening or improving economic conditions. As of March 31, 2026, the Company assigned the same weighting to each of its upside, downside and baseline scenarios as compared with December 31, 2025. Compared with the December 2025 forecast, the March 2026 baseline forecast for GDP growth showed improvement in the near term and deterioration starting the fourth quarter of 2026. Unemployment rates have also decreased slightly in the current forecast due to lower forecasted labor force growth. The downside scenario assumed the economy falls into recession in the second quarter of 2026 as a result of rising oil prices, inflation, tariffs, deportations, and still-elevated interest rates. The upside scenario assumed a more optimistic economic outlook, including faster resolutions to global conflicts, stronger growth, stable financial markets, and full employment starting in the second quarter of 2026. Loan Transfers, Sales and Purchases The Company’s primary business focus is on directly originated loans. The Company also purchases loans from and participates in loan financing with other banks. In the normal course of business, the Company also provides other financial institutions with the ability to participate in commercial loans that it originates, by selling loans to such institutions. Purchased loans may be transferred from held-for-investment to held-for-sale, and write-downs to ALLL are recorded, when appropriate. The following tables provide information on the carrying value of loans transferred, sold and purchased, during the three months ended March 31, 2026 and 2025: Three Months Ended March 31, 2026 Commercial Consumer CRE Residential Mortgage ($ in thousands) C&I Multifamily Residential SFR Total Loans transferred from held-for-investment to held-for-sale (1) $ 101,777   $ 9,959   $ 5,345   $ 117,081   Sales (2)(3) $ 98,280   $ 9,959   $ 363   $ 108,602   Purchases $ 109,892   (4) $ —   $ 140,511   $ 250,403   Three Months Ended March 31, 2025 Commercial Consumer CRE Residential Mortgage ($ in thousands) C&I CRE Construction and Land SFR Total Loans transferred from held-for-investment to held-for-sale (1) $ 6,356   $ 20,338   $ 9,500   $ —   $ 36,194   Sales (2)(3) $ 6,356   $ 20,338   $ 11,316   $ —   $ 38,010   Purchases $ 136,943   (4) $ —   $ —   $ 87,364   $ 224,307   (1) Includes write-downs of $ 2 million to the allowance for loan losses related to loans transferred from held-for-investment to held-for-sale for each of the three months ended March 31, 2026 and 2025. (2) Includes originated loans sold of $ 69 million and $ 34 million for the three months ended March 31, 2026 and 2025, respectively. Originated loans sold were primarily comprised of C&I loans for the three months ended March 31, 2026, and CRE and construction loans for the three months ended March 31, 2025. (3) Includes $ 39 million and $ 4 million of purchased loans sold in the secondary market for the three months ended March 31, 2026 and 2025, respectively. (4) C&I loan purchases were comprised of syndicated C&I term loans. 47 Note 7 — Affordable Housing Partnership, Tax Credit and Community Reinvestment Act Investments, Net The CRA encourages banks to meet the credit needs of their communities, particularly low- and moderate-income individuals and neighborhoods. The Company invests in certain affordable housing projects in the form of ownership interests in limited partnerships or limited liability companies that qualify for CRA consideration and tax credits. These entities are formed to develop and operate apartment complexes designed as high-quality affordable housing for lower income tenants throughout the U.S. To fully utilize the available tax credits, each of these entities must meet the affordable housing regulatory requirements for a 15-year minimum compliance period. The Company also invests in small business investment companies and new markets tax credit projects that qualify for CRA consideration, as well as eligible projects that qualify for production, historic and renewable energy tax credits. Investments in new markets tax credits promote development in low-income communities; investments in production and renewable energy tax credits help promote the development of renewable energy sources; and investments in historic tax credits promote the rehabilitation of historic buildings and economic revitalization of the surrounding areas. The majority of the affordable housing partnership, tax credit and CRA investments discussed above are variable interest entities where the Company is a limited partner in these investments, and an unrelated third party is typically the general partner or managing member who has control over the significant activities of these investments. While the Company’s interest in some of the investments may exceed 50% of the outstanding equity interests, the Company does not consolidate these investments due to the general partner’s or managing member’s ability to manage the entity, which is indicative of the general partner’s or managing member’s power over the entity. The Company’s maximum exposure to loss in connection with these partnerships consists of the unamortized investment balance and any tax credits claimed that may become subject to recapture. The Company elects to account for its tax credit investments using the proportional amortization method (“PAM”) on a program-by-program basis if certain conditions are met. For the Company’s accounting policies on PAM, see Note 1 — Summary of Significant Accounting Policies — Significant Accounting Policies — Income Taxes to the Consolidated Financial Statements in the Company’s 2025 Form 10-K. For discussion on the Company’s impairment evaluation and monitoring process for tax credit investments, refer to Note 2 — Fair Value Measurement and Fair Value of Financial Instruments — Affordable Housing Partnership, Tax Credit and CRA Investments, Net to the Consolidated Financial Statements in this Form 10-Q.

(3) For affordable housing partnership, tax credit and CRA investments that are qualified for accounting under PAM, amortization is included in Income tax expense on the Consolidated Statement of Income. (4) For tax credit and CRA investments that are not accounted for under PAM, amortization is included in Amortization of tax credit and CRA investments as part of Noninterest expense on the Consolidated Statement Income. The Company also held equity securities without readily determinable fair values totaling $ 117 million as of both March 31, 2026 and December 31, 2025, included in Other Assets on the Consolidated Balance Sheet. Note 8 — Federal Home Loan Bank Advances and Long-Term Debt The following table presents details of the Company’s FHLB advances and long-term debt as of March 31, 2026 and December 31, 2025: March 31, 2026 December 31, 2025 ($ in thousands) Interest Rates Maturity Dates Amount Amount Parent company Junior subordinated debt — floating (1)   5.49 % 12/15/2035 $ 32,400   $ 32,320   Bank FHLB advances (2) : Floating (3) 3.78 % — 3.88 % 2026 — 2027 $ 1,900,000   $ 2,000,000   Fixed 3.87 % — 3.95 % 2026 1,100,000   750,000   Overnight N/A N/A —   250,000   Total FHLB advances $ 3,000,000   $ 3,000,000   N/A — Not applicable. (1) As of March 31, 2026, the outstanding junior subordinated debt was issued by MCBI Statutory Trust I and had a stated interest of 3-month CME Term Secured Overnight Financing Rate (“SOFR”) + 1.81 %. The contractual interest rates for junior subordinated debt were 5.49 % and 5.53 % as of March 31, 2026 and December 31, 2025, respectively. For additional information on the junior subordinated debt, refer to Note 10 - Federal Home Loan Bank Advances and Long-Term Debt in the Company’s 2025 Form 10-K. (2) The weighted-average interest rates for FHLB advances were 3.87 % and 3.94 % as of March 31, 2026 and December 31, 2025, respectively. (3) Floating interest rates are based on the SOFR plus the established spread. 49 The Bank’s available borrowing capacity from FHLB advances totaled $ 11.7  billion as of March 31, 2026. The Bank’s available borrowing capacity from the FHLB is derived from its portfolio of loans that are pledged to the FHLB, reduced by any outstanding FHLB advances and standby letters of credit (“SBLC”). As of March 31, 2026, all advances were secured by real estate loans. Note 9 — Commitments and Contingencies Commitments to Extend Credit — In the normal course of business, the Company provides loan commitments and letters of credit to customers on predetermined terms. These outstanding commitments to extend credit are not reflected in the accompanying Consolidated Financial Statements. The following table presents the Company’s credit-related commitments as of March 31, 2026 and December 31, 2025: March 31, 2026 December 31, 2025 ($ in thousands) Expire in One Year or Less Expire After One Year Through Three Years Expire After Three Years Through Five Years Expire After Five Years Total Total Loan commitments $ 4,699,796   $ 3,405,090   $ 855,790   $ 219,462   $ 9,180,138   $ 9,623,963   Commercial letters of credit and SBLCs 1,339,368   566,099   152,788   934,073   2,992,328   2,956,290   Total $ 6,039,164   $ 3,971,189   $ 1,008,578   $ 1,153,535   $ 12,172,466   $ 12,580,253   Loan commitments are agreements to lend to customers provided there are no violations of any conditions established in the agreement. Commitments generally have fixed expiration dates or other termination clauses and may require commitment fees. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future funding requirements. Commercial letters of credit are issued to facilitate domestic and foreign trade transactions, while SBLCs are generally contingent upon the failure of the customers to perform according to the terms of the underlying contract with the third party. As a result, the total contractual amounts do not necessarily represent future funding requirements. The Company’s historical experience is that SBLCs typically expire without being funded. Additionally, in many cases, the Company holds collateral in various forms against these SBLCs. As part of its risk management activities, the Company monitors the creditworthiness of customers in conjunction with its SBLC exposure. Customers are obligated to reimburse the Company for any payment made on the customers’ behalf. If the customers fail to pay, the Company would, as applicable, liquidate the collateral and/or offset existing accounts. As of March 31, 2026, total letters of credit of $ 3.0 billion consisted of SBLCs of $ 3.0 billion and commercial letters of credit of $ 39 million. In comparison, as of December 31, 2025, total letters of credit of $ 3.0 billion consisted of SBLCs of $ 2.9 billion and commercial letters of credit of $ 31 million. As of both March 31, 2026 and December 31, 2025, substantially all letters of credit were graded “Pass” using the Bank’s internal credit risk rating system. The Company applies the same credit underwriting criteria to extend loans, commitments, and conditional obligations to customers. Each customer’s creditworthiness is evaluated on a case-by-case basis. Collateral and financial guarantees may be obtained based on management’s assessment of a customer’s credit risk. Collateral may include cash, accounts receivable, inventory, personal property, plant and equipment, and real estate property. Estimated exposure to loss from these commitments is included in the allowance for unfunded credit commitments and amounted to $ 47 million and $ 49 million as of March 31, 2026 and December 31, 2025, respectively. For further information on the allowance for unfunded credit commitments, refer to Note 6 — Loans Receivable and Allowance for Credit Losses to the Consolidated Financial Statements in this Form 10-Q. 50 Guarantees — The Company occasionally sells or securitizes single-family and multifamily residential loans with recourse in the ordinary course of business. The Company is obligated to repurchase up to the recourse component of the loans if the loans default. The following table presents the maximum potential future payments and carrying value of loans sold or securitized with recourse as of March 31, 2026 and December 31, 2025: Maximum Potential Future Payments Carrying Value (1) March 31, 2026 December 31, 2025 March 31, 2026 December 31, 2025 ($ in thousands) Expire After One Year Through Three Years Expire After Three Years Through Five Years Expire After Five Years Total Total Total Total SFR loans sold or securitized with recourse $ 14   $ 397   $ 2,580   $ 2,991   $ 3,137   $ 2,991   $ 3,137   Multifamily residential loans sold or securitized with recourse 116   39   14,841   14,996   14,996   15,595   15,895   Total $ 130   $ 436   $ 17,421   $ 17,987   $ 18,133   $ 18,586   $ 19,032   (1) Represents the unpaid principal balance. The Company continues to experience minimal losses from the single-family and multifamily residential loan portfolios sold or securitized with recourse and recorded an immaterial recourse reserve as of both March 31, 2026 and December 31, 2025. Litigation — The Company is a party to various legal actions arising in the ordinary course of its business. In accordance with ASC 450, Contingencies, the Company accrues reserves for outstanding lawsuits, claims and proceedings when a loss contingency is probable and can be reasonably estimated. The Company estimates the amount of loss contingencies using current available information from legal proceedings, advice from legal counsel and available insurance coverage. Due to the inherent subjectivity of the assessments and unpredictability of the outcomes of the legal proceedings, any amounts accrued or included in this aggregate amount may not represent the ultimate loss to the Company from the legal proceedings in question. Thus, the Company’s exposure and ultimate losses may be higher, and possibly significantly more, than the amounts accrued. While it is impossible to ascertain the ultimate resolution or range of financial liability, based on information known to the Company as of March 31, 2026, the Company does not believe there are any pending legal proceedings to which the Company is a party that, individually or in the aggregate, would reasonably be expected to have a material adverse effect on the Company’s financial condition. In light of the inherent uncertainty in legal proceedings, however, there can be no assurance that the ultimate resolution will not exceed established reserves and it is possible that the outcome of a particular matter, or a combination of matters, may be material to the Company’s financial condition for a particular period, depending upon the size of the loss and the Company’s income for that particular period. Note 10 — Stock Compensation Plans Pursuant to the Company’s 2021 Stock Incentive Plan, as amended, the Company may issue stock, stock options, restricted stock, RSUs including performance-based RSUs, stock purchase warrants, stock appreciation rights, phantom stock and dividend equivalents to eligible employees, non-employee directors, consultants, and other service providers of East West and its subsidiaries. The Company has granted RSUs as its primary incentive awards. There were no outstanding awards other than RSUs as of both March 31, 2026 and December 31, 2025. 51 The following table presents a summary of the total share-based compensation expense and the related net tax benefits associated with the Company’s various employee share-based compensation plans for the three months ended March 31, 2026 and 2025: Three Months Ended March 31, ($ in thousands) 2026 2025 Stock compensation costs $ 19,837   $ 13,186   Related net tax benefits for stock compensation plans $ 6,934   $ 2,655   Restricted Stock Units — RSUs are granted under the Company’s long-term incentive plan at no cost to the recipient. RSUs generally cliff vest after three years of continued employment from the date of the grant and are authorized to settle in shares of the Company’s common stock. Dividends are accrued during the vesting period and paid at the time of vesting. While a portion of the RSU grants are time-based vesting awards, other RSUs vest subject to the attainment of additional specified performance goals, referred to as “performance-based RSUs.” Performance-based RSUs are granted annually upon approval by the Company’s Compensation and Management Development Committee based on the performance in the year prior to the grant date of the award. The number of awards that vest can range from 0 % to a maximum of 200 % of the target number of awards based on the Company’s achievement of specified performance criteria over a performance period of three years . For information on accounting on stock-based compensation plans, see Note 1 — Summary of Significant Accounting Policies — Significant Accounting Policies — Stock-Based Compensation to the Consolidated Financial Statements of the Company’s 2025 Form 10-K.

Note 13 — Business Segments The Company organizes its operations into three reportable operating segments: (1) Consumer and Business Banking; (2) Commercial Banking; and (3) Treasury and Other. These segments are defined based on customer type, the channels through which customers are served, and the products and services provided. The chief operating decision maker (“CODM”) is the Chairman and Chief Executive Officer of the Company. The CODM regularly reviews the Company’s operating results to allocate resources and assess performance. Operating segment results are also based on the Company’s internal management reporting process, which reflects the allocations of certain balance sheet and income statement line items. The CODM uses certain performance measures such as segment net income and considers variances of actual results from forecast results on a quarterly basis when making decisions on resource allocations between segments. The segment information presented is not indicative of how the segments would perform if they operated as independent entities. The Consumer and Business Banking segment primarily provides financial products and services to consumer and commercial customers through the Company’s domestic branch network and digital banking platforms. This segment offers consumer and commercial deposits, mortgage and home equity loans, and other products and services. It also originates commercial loans for small- and medium-sized enterprises through the Company’s branch network. Other products and services provided by this segment include wealth management, private banking, treasury management, interest rate risk hedging and foreign exchange services. The Commercial Banking segment primarily generates commercial loan and deposit products. Commercial loan products include CRE lending, construction finance, commercial business lending, working capital lines of credit, trade finance, letters of credit, affordable housing lending, asset-based lending, asset-backed finance, project finance, equipment financing, and loan syndication. Commercial deposit products and other financial services include treasury management, foreign exchange services and interest rate and commodity risk hedging. 54 The remaining centralized functions, including the corporate treasury activities of the Company, tax credit investment activities, eliminations of inter-segment amounts, and centrally managed departments, have been aggregated and included in the Treasury and Other segment. The Company utilizes an internal reporting process to measure the performance of the three operating segments within the Company. The Company’s internal reporting process consists of certain allocation methodologies for revenues and expenses, and the internal funds transfer pricing (“FTP”) process. The FTP process is formulated with the goal of encouraging loan and deposit growth that is consistent with the Company’s overall profitability objectives, as well as providing a reasonable and consistent basis for the measurement of business segment net interest margins and profitability. The FTP process charges a cost to fund loans (“FTP charges for loans”) and allocates credits for funds provided from deposits (“FTP credits for deposits”) using internal FTP rates. FTP charges for loans are determined based on a matched cost of funds, which is tied to the pricing and term characteristics of the loans. FTP credits for deposits are based on matched funding credit rates, which are tied to the implied or stated maturity of the deposits. FTP credits for deposits reflect the long-term value generated by the deposits. The net spread between the total internal FTP charges and credits is recorded as part of net interest income in the Treasury and Other segment. The corporate treasury function within the Treasury and Other segment is responsible for the Company’s liquidity and interest rate management and manages the corporate interest rate risk exposure. The Company’s internal FTP assumptions and methodologies are reviewed at least annually to ensure that the process is reflective of current market conditions. Each segment’s net interest income represents the difference between actual interest earned on assets and interest incurred on liabilities of the segment, adjusted for funding charges or credits through the Company’s FTP process. Noninterest income and noninterest expense directly attributable to a business segment are assigned to that segment. Loan charge-offs and provision for credit losses are recorded to the segments where the loans are recorded. Significant corporate overhead expenses incurred by centralized support areas in the Treasury and Other segment are allocated to the Consumer and Business Banking and Commercial Banking segments based on the segment’s estimated usage factors including, but not limited to, full-time equivalent employees, net interest income, and loan and deposit volume. Amortization of tax credit and CRA investments and certain types of administrative expenses are generally not allocated to segments.

(referred to herein on an unconsolidated basis as “East West” and on a consolidated basis as the “Company,” “we,” “our” or “EWBC”) and its subsidiaries, including its subsidiary bank, East West Bank and its subsidiaries (referred to herein as “East West Bank” or the “Bank”). This information is intended to facilitate the understanding and assessment of significant changes and trends related to the Company’s results of operations and financial condition. This discussion and analysis should be read in conjunction with the Consolidated Financial Statements and the accompanying notes presented elsewhere in this Quarterly Report on Form 10-Q (this “Form 10-Q”), and the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, filed with the United States (“U.S.”) Securities and Exchange Commission (“SEC”) on February 27, 2026 (the “Company’s 2025 Form 10-K”). Organization and Strategy East West is a bank holding company incorporated in Delaware on August 26, 1998, and is registered under the Bank Holding Company Act of 1956, as amended. The Company commenced business on December 30, 1998 when, pursuant to a reorganization, it acquired all of the voting stock of the Bank, which became its principal asset. The Bank is an independent commercial bank headquartered in California that focuses on the financial service needs of individuals and businesses that operate in both the U.S. and Asia. Through over 110 locations in the U.S. and Asia, the Company provides a full range of consumer and commercial products and services through the following three business segments: (1) Consumer and Business Banking and (2) Commercial Banking, with the remaining operations recorded in (3) Treasury and Other . The Company’s principal activity is lending to and accepting deposits from businesses and individuals. We are committed to enhancing long-term shareholder value by growing loans, deposits and revenue, improving profitability, and investing for the future while managing risks, expenses and capital. Our business model is built on customer loyalty and engagement, understanding our customers’ financial goals, and meeting our customers’ financial needs through our diverse products and services. We expect our relationship-focused business model to continue generating organic growth from existing customers and to expand our targeted customer bases. As of March 31, 2026, the Company had $82.9 billion in total assets and approximately 3,400 full-time equivalent employees. For additional information on our strategy, and the products and services provided by the Bank, see Item 1. Business — Organization and Banking Services in the Company’s 2025 Form 10-K. Current Developments Economic Developments Evolving geopolitical uncertainties, including armed conflict involving Iran or heightened tensions in other regions, as well as changes in trade policies and tariffs, continue to raise concerns about inflation, oil and energy price volatility, and supply chain disruptions. At its March and April 2026 meetings, the Federal Reserve maintained the federal funds target rate, reflecting a cautious stance as it manages persistent inflationary pressures and a gradually cooling labor market amid an increasingly uncertain global environment. These factors may create volatility that could affect both inflation and overall economic growth. The Company monitors changes in economic and industry conditions and their impacts on the Company’s business, customers, employees, communities and markets. Further discussion of the potential impacts on the Company’s business due to the economic environment has been provided in Item 1A. — Risk Factors — Risks Related to Geographic and Political Uncertainties and — Risks Related to Financial Matters in the Company’s 2025 Form 10-K. Regulatory Updates In March 2026, the federal banking agencies issued proposed revisions to the U.S. regulatory capital framework. The proposals would, among other things, modify aspects of the standardized approach to risk-based capital treatment of certain exposure categories that are material to the Company. The proposed changes address the definition of capital, the calculation of certain risk-weighted assets and future indexing of certain dollar-based thresholds. The Company has been monitoring these proposals and assessing their potential impacts on its regulatory capital position. 58 Financial Review Three Months Ended March 31, ($ and shares in thousands, except per share, and ratio data) 2026 2025 Summary of operations: Net interest income before provision for credit losses $ 671,193  $ 600,201  Noninterest income 102,556  92,102  Total revenue 773,749  692,303  Provision for credit losses 36,000  49,000  Noninterest expense 280,314  252,148  Income before income taxes 457,435  391,155  Income tax expense 99,639  100,885  Net income $ 357,796  $ 290,270  Per share: Basic earnings $ 2.59  $ 2.10  Diluted earnings $ 2.57  $ 2.08  Dividends declared $ 0.80  $ 0.60  Weighted-average number of shares outstanding: Basic 138,054  138,201  Diluted 138,919  139,291  Performance metrics: Return on average assets (“ROA”) 1.79  % 1.56  % Return on average common equity (“ROAE”) 16.04  % 14.96  % Return on average tangible common equity (“ROATCE”) (1) 16.92  % 15.92  % Common dividend payout ratio 31.16  % 28.97  % Net interest margin 3.49  % 3.35  % Efficiency ratio (2) 36.23  % 36.42  % At period end: March 31, 2026 December 31, 2025 Total assets $ 82,886,152  $ 80,434,997  Total loans $ 58,128,334  $ 56,899,148  Total deposits $ 68,919,555  $ 67,082,701  Common shares outstanding at period-end 136,979  137,579  Book value per share $ 65.70  $ 64.68  Tangible book value per share (1) $ 62.27  $ 61.27  (1) For additional information regarding the reconciliation of these non-U.S. Generally Accepted Accounting Principles (“GAAP”) financial measures, refer to Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) — Reconciliation of GAAP to Non-GAAP Financial Measures in this Form 10-Q. (2) Efficiency ratio is calculated as noninterest expense divided by total revenue. The Company’s net income for the first quarter 2026 was $358 million, a $68 million or 23% increase from the same prior year period. The year-over-year increase was primarily driven by higher net interest income before provision for credit losses, lower provision for credit losses, and increased noninterest income, partially offset by higher noninterest expense. Noteworthy aspects of the Company’s performance for the first quarter of 2026 included: • Net interest income and net interest margin . First quarter 2026 net interest income before provision for credit losses of $671 million increased $71 million or 12% from the first quarter of 2025. First quarter 2026 net interest margin of 3.49% increased 14 bps year-over-year. • Earnings per share growth. First quarter 2026 basic and diluted earnings per share both increased 23% to $2.59 and $2.57, respectively, from the first quarter of 2025. 59 • Profitability ratios. First quarter 2026 ROA, ROAE and the ROATCE of 1.79%, 16.04% and 16.92%, respectively, increased 23 bps, 108 bps and 100 bps year-over-year, respectively. ROATCE is a non-GAAP financial measure. For additional information regarding the reconciliation of non-GAAP financial measures, refer to Item 2. MD&A — Reconciliation of GAAP to Non-GAAP Financial Measures in this Form 10-Q. • Efficiency ratios. First quarter 2026 efficiency ratio was 36.23%, compared with 36.42% for the same period in 2025. The improvement in the efficiency ratio was primarily due to higher net interest income before provision for credit losses and an increase in noninterest income. • Asset growth. Total assets reached $82.9 billion as of March 31, 2026, an increase of $2.5 billion from December 31, 2025, primarily driven by a $1.2 billion or 2% increase in net loans held-for-investment and an $881 million or 7% increase in available-for-sale (“AFS”) debt securities. • Deposit growth. Total deposits were $68.9 billion as of March 31, 2026, an increase of $1.8 billion or 3%, from December 31, 2025, primarily driven by growth in money market and noninterest-bearing demand deposits. • Capital levels. Stockholders’ equity was $9.0 billion as of March 31, 2026, up $100 million or 1%, from December 31, 2025. Book value per share of $65.70 as of March 31, 2026, increased $1.02 or 2%, compared with December 31, 2025. Tangible book value per share of $62.27 as of March 31, 2026, increased $1.00 or 2%, compared with December 31, 2025. Tangible book value per share is a non-GAAP financial measure. For additional details, see the reconciliation of non-GAAP financial measures presented under Item 2. MD&A — Reconciliation of GAAP to Non-GAAP Financial Measures in this Form 10-Q. Results of Operations Net Interest Income The Company’s primary source of revenue is net interest income, which is the interest income earned on interest-earning assets less interest expense paid on interest-bearing liabilities. Net interest margin is the ratio of net interest income to average interest-earning assets. Net interest income and net interest margin are impacted by several factors, including changes in average balances and the composition of interest-earning assets and funding sources, market interest rate fluctuations and the slope of the yield curve, repricing characteristics and maturity of interest-earning assets and interest-bearing liabilities, the volume of noninterest-bearing sources of funds and asset quality. 60 Net interest income and net interest margin for the first quarter of 2026 increased year-over-year. The $71 million or 12% year-over-year increase in net interest income, and the 14 bp year-over-year increase in net interest margin primarily reflected lower interest-bearing deposit funding costs and Federal Home Loan Bank (“FHLB”) advances, and increases in loans and AFS debt securities’ average balances, partially offset by lower yields on loans, AFS debt securities, and interest-bearing cash and deposits with banks. Average interest-earning assets were $78.0 billion for the first quarter of 2026, an increase of $5.3 billion or 7% from the first quarter of 2025. The year-over-year increase in average interest-earning assets primarily reflected loan growth and increases in AFS debt securities, partially offset by decreases in interest-bearing cash and deposits with banks. The 27 bp year-over-year decrease in the yield on average interest-earning assets to 5.49% for the first quarter of 2026, primarily reflected the impact of lower benchmark interest rates on the loan portfolio. The average loan yield of 6.11% for the first quarter of 2026, decreased 28 bps, from the first quarter of 2025. The year-over-year decrease in the average loan yield primarily reflected the loan portfolio’s sensitivity to lower benchmark interest rates. Approximately 59% and 58% of loans held-for-investment were variable-rate as of March 31, 2026 and 2025, respectively. 61 Deposits are an important source of funding for the Company. Average deposits were $67.5 billion for the first quarter of 2026, a $4.9 billion or 8% increase from the first quarter of 2025. The year-over-year increase was primarily driven by growth in time, demand and money market deposits. Average noninterest-bearing deposits were $16.9 billion for the first quarter of 2026, a $1.8 billion or 12% increase from the first quarter of 2025. The average cost of deposit s of 2.13% for the first quarter of 2026, decreased 41 bps from the first quarter of 2025 . The average cost of interest-bearing de posits of 2.84% for the first quarter of 2026, decreased 50 bps, from the first quarter of 2025. These year-over-year decreases primarily reflected the impacts of lower benchmark interest rates and the Company’s efforts to reduce deposit costs. The average cost of funds calculation includes deposits, FHLB advances, securities sold under repurchase agreements (“repurchase agreements”), long-term debt, and short-term borrowings. The average cost of funds of 2.21% for the first quarter of 2026 decreased 43 bps , from the first quarter of 2025. The year-over-year decrease was mainly driven by the decrease in the cost of deposits as discussed above. The Company utilizes various tools to manage interest rate risk.

Noninterest income for the first quarter of 2026 was $103 million, a $10 million or 11% increase compared with the first quarter of 2025. The year-over-year increase was primarily due to increases in wealth management fees, commercial and consumer deposit-related fees, and customer derivative income and derivative mark-to-market adjustments, partially offset by other losses. Commercial and consumer deposit-related fees were $31 million for the first quarter of 2026, a $4 million or 13% increase compared with the first quarter of 2025. The year-over-year increase was primarily due to higher commercial customer activity. Wealth management fees were $22 million for the first quarter of 2026, a $9 million or 63% increase compared with the first quarter of 2025. The year-over-year increase primarily reflected higher customer demand for wealth management products such as fixed-rate corporate bonds and fixed annuities and increased commission and fees from new customer activity. Customer derivative income and derivative mark-to-market adjustments were $6 million for the first quarter of 2026, a $1 million increase compared with the first quarter of 2025. The year-over-year increase primarily reflected favorable credit valuation adjustments, partially offset by lower customer activity. Other losses were $941 thousand for the first quarter of 2026, compared with other income of $3 million in the first quarter of 2025. The decrease primarily reflected $5 million in lower of cost or market adjustments on loans held-for-sale recorded during the first quarter of 2026. 65 Noninterest Expense The following table presents the components of noninterest expense for the first quarters of 2026 and 2025: Three Months Ended March 31, ($ in thousands) 2026 2025 % Change Compensation and employee benefits $ 172,665  $ 146,435  18  % Occupancy and equipment expense 18,248  15,689  16  % Computer and software related expenses 14,747  13,314  11  % Deposit insurance premiums and regulatory assessments 8,859  10,385  (15) % Deposit account expense 7,533  9,042  (17) % Other real estate owned (“OREO”) (income) expense (264) 4,166  NM Other operating expense 36,542  37,375  (2) % Amortization of tax credit and Community Reinvestment Act (“CRA”) investments 21,984  15,742  40  % Total noninterest expense $ 280,314   $ 252,148   11   % NM - Not meaningful. Noninterest expense was $280 million for the first quarter of 2026, a $28 million or 11% increase compared with the first quarter of 2025. The year-over-year increase was primarily due to increases in compensation and employee benefits and amortization of tax credit and CRA investments, partially offset by OREO income. Compensation and employee benefits were $173 million for the first quarter of 2026, a $26 million or 18% increase compared with the first quarter of 2025. The increase was primarily driven by higher incentive compensation and staffing growth. Occupancy and equipment expense was $18 million for the first quarter of 2026, a $3 million or 16% increase compared with the first quarter of 2025. The increase was primarily due to higher rental expense and increased depreciation related to a building purchase. OREO income was $264 thousand for the first quarter of 2026, compared with OREO expense of $4 million for the first quarter of 2025. OREO income of $264 thousand for the first quarter of 2026 was primarily due to gains recorded on the sale of an OREO property, partially offset by OREO write-downs and operating expenses, compared with $4 million of OREO write-downs for the same prior year period. Amortization of tax credit and CRA investments was $22 million for the first quarter of 2026, a $6 million or 40% increase compared with the first quarter of 2025. The year-over-year increase was primarily due to the timing of tax credit investments that closed in a given period. Income Taxes The following table presents income before income taxes, income tax expense and the effective tax rate for the first quarters of 2026 and 2025: Three Months Ended March 31, ($ in thousands) 2026 2025 % Change Income before income taxes $ 457,435  $ 391,155  17  % Income tax expense $ 99,639  $ 100,885  (1) % Effective tax rate 21.8  % 25.8  % First quarter 2026 income tax expense was $100 million and the effective tax rate was 21.8%, compared with first quarter 2025 income tax expense of $101 million and an effective tax rate of 25.8%. The decreases in income tax expense and effective tax rate were primarily due to the release of valuation allowance associated with foreign tax credits and favorable adjustments driven by a lower California state tax apportionment, partially offset by higher pre-tax income and a partial derecognition of a purchased tax credit. 66 Operating Segment Results The Company organizes its operations into three reportable operating segments: (1) Consumer and Business Banking; (2) Commercial Banking; and (3) Treasury and Other. These segments are defined based on customer type, the channels through which customers are served, and the products and services provided. For a description of the Company’s internal management reporting process, including the segment cost allocation methodology, see Note 13 — Business Segments to the Consolidated Financial Statements in this Form 10-Q. Segment net interest income represents the difference between actual interest earned on assets and interest incurred on liabilities of the segment, adjusted for funding charges or credits through the Company’s internal funds transfer pricing (“FTP”) process. Consumer and Business Banking The Consumer and Business Banking segment primarily provides financial products and services to consumer and commercial customers through the Company’s domestic branch network and digital banking platforms. This segment offers consumer and commercial deposits, mortgage and home equity loans, and other products and services. It also originates commercial loans for small- and medium-sized enterprises through the Company’s branch network. Other products and services provided by this segment include wealth management, private banking, treasury management, interest rate risk hedging and foreign exchange services. The following table presents financial information for the Consumer and Business Banking segment for the periods indicated: Three Months Ended March 31, Change from 2025 ($ in thousands) 2026 2025 $ % Net interest income before provision for credit losses $ 269,247  $ 269,733  $ (486) 0  % Noninterest income 39,962  32,285  7,677  24  % Total revenue before provision for credit losses 309,209  302,018  7,191  2  % Provision for credit losses 9,185  7,685  1,500  20  % Compensation and employee benefits 70,096  61,964  8,132  13  % Other noninterest expense 62,005  57,192  4,813  8  % Total noninterest expense 132,101  119,156  12,945  11  % Segment income before income taxes 167,923  175,177  (7,254) (4) % Income tax expense 47,059  52,089  (5,030) (10) % Segment net income $ 120,864  $ 123,088  $ (2,224) (2) % Average loans $ 21,034,978  $ 19,762,287  $ 1,272,691  6  % Average deposits $ 35,048,413  $ 32,326,906  $ 2,721,507  8  % Consumer and Business Banking segment net income decreased $2 million or 2% year-over-year to $121 million for the first quarter of 2026, primarily driven by an $8 million increase in compensation and employee benefits and a $5 million increase in other noninterest expense, partially offset by an $8 million increase in noninterest income. The increase in noninterest income was mainly driven by higher wealth management fee income in the first quarter of 2026. The compensation and employee benefits increase was primarily due to higher incentive compensation, increased wealth management commissions and staffing growth. The increase in other noninterest expense was mainly driven by higher allocated corporate overhead expenses. Commercial Banking The Commercial Banking segment primarily generates commercial loan and deposit products. Commercial loan products include CRE lending, construction finance, commercial business lending, working capital lines of credit, trade finance, letters of credit, affordable housing lending, asset-based lending, asset-backed finance, project finance, equipment financing, and loan syndication. Commercial deposit products and other financial services include treasury management, foreign exchange services, and interest rate and commodity risk hedging. 67 The following table presents financial information for the Commercial Banking segment for the periods indicated: Three Months Ended March 31, Change from 2025 ($ in thousands) 2026 2025 $ % Net interest income before provision for credit losses $ 261,286  $ 253,001  $ 8,285  3  % Noninterest income 54,331  53,579  752  1  % Total revenue before provision for credit losses 315,617  306,580  9,037  3  % Provision for credit losses 27,007  40,779  (13,772) (34) % Compensation and employee benefits 74,844  61,187  13,657  22  % Other noninterest expense 36,470  42,318  (5,848) (14) % Total noninterest expense 111,314  103,505  7,809  8  % Segment income before income taxes 177,296  162,296  15,000  9  % Income tax expense 49,657  48,271  1,386  3  % Segment net income $ 127,639  $ 114,025  $ 13,614  12  % Average loans $ 36,019,671  $ 33,211,037  $ 2,808,634  8  % Average deposits (1) $ 28,087,719  $ 26,129,141  $ 1,958,578  7  % (1) Prior period balances have been reclassified for comparability due to a change in allocation methodology. Commercial Banking segment net income increased $14 million or 12% year-over-year to $128 million for the first quarter of 2026, primarily driven by a $14 million decrease in provision for credit losses, an $8 million increase in net interest income and a $6 million decrease in other noninterest expense, partially offset by a $14 million increase in compensation and employee benefits. The net interest income increase was primarily due to commercial loan and deposit growth, leading to higher interest earnings and internal FTP credits from deposits in the first quarter of 2026, respectively. The decrease in provision for credit losses was driven by a more stable macroeconomic environment for C&I loans in the first quarter of 2026. The increase in compensation and employee benefits was primarily driven by higher incentive compensation and staffing growth. The decrease in other noninterest expense was mainly due to lower OREO and loan related expenses in the first quarter of 2026. Treasury and Other Centralized functions, including the corporate treasury activities of the Company, tax credit investment activities , eliminations of inter-segment amounts, and centrally managed departments, have been aggregated and included in the Treasury and Other segment. 68 The following table presents financial information for the Treasury and Other segment for the periods indicated: Three Months Ended March 31, Change from 2025 ($ in thousands) 2026 2025 $ % Net interest income before (reversal of) provision for credit losses $ 140,660  $ 77,467  $ 63,193  82  % Noninterest income 8,263  6,238  2,025  32  % Total revenue before (reversal of) provision for credit losses 148,923  83,705  65,218  78  % (Reversal of) provision for credit losses (192) 536  (728) NM Compensation and employee benefits 27,725  23,284  4,441  19  % Other noninterest expense 9,174  6,203  2,971  48  % Total noninterest expense 36,899  29,487  7,412  25  % Segment income before income taxes 112,216  53,682  58,534  109  % Income tax expense 2,923  525  2,398  NM Segment net income $ 109,293  $ 53,157  $ 56,136  106  % Average loans (1) $ —  $ 364,387  $ (364,387) (100) % Average deposits (2) $ 4,411,502  $ 4,181,535  $ 229,967  5  % NM — Not meaningful. (1) Reallocated to the Commercial Banking and Consumer and Business Banking segments effective first quarter of 2026. (2) Prior period balances have been reclassified for comparability due to a change in allocation methodology. The Treasury and Other segment income before income taxes increased $59 million for the first quarter of 2026, primarily driven by a $63 million increase in net interest income, partially offset by a $4 million increase in compensation and employee benefits and a $3 million increase in other noninterest expense. The net interest income increase was mainly driven by lower net internal FTP credits for deposits to other business segments, lower interest expense on FHLB advances, and higher interest income on debt securities during the first quarter of 2026. The compensation and employee benefits increase was primarily driven by higher incentive compensation and staffing growth. The other noninterest expense increase was primarily driven by higher amortization of tax credit and CRA investments. Income tax expense is allocated to the Consumer and Business Banking and the Commercial Banking segments by applying statutory income tax rates to the respective segment income before income taxes. The income tax expense or benefit in the Treasury and Other segment consists of the remaining unallocated income tax expense or benefit after allocating income tax expense to the two core segments, and reflects the impact of tax credit investment activity. Balance Sheet Analysis Debt Securities The Company maintains a portfolio of high quality and liquid debt securities with a moderate duration profile. It closely manages the overall portfolio credit, interest rate and liquidity risks. The Company’s debt securities provide: • interest income for earnings and yield enhancement; • funding availability for needs arising during the normal course of business; • the ability to execute interest rate risk management strategies in response to changes in economic or market conditions; and • collateral to support pledging agreements as required and/or to enhance the Company’s borrowing capacity. While the Company does not intend to sell or trade its debt securities, it may sell AFS debt securities in response to changes in the balance sheet and related interest rate risk to meet liquidity, regulatory and strategic requirements. 69 The following table presents the distribution of the Company’s AFS and HTM debt securities portfolio by amortized cost and fair value as of March 31, 2026 and December 31, 2025, and by credit ratings as of March 31, 2026: March 31, 2026 December 31, 2025 Ratings as of March 31, 2026 (1) ($ in thousands) Amortized Cost Fair Value % of Fair Value Amortized Cost Fair Value % of Fair Value AAA/AA A BBB BB and Lower AFS debt securities: U.S. Treasury securities $ 1,256,350  $ 1,237,787  9 % $ 1,010,053  $ 993,913  7 % 100 % — % — % — % U.S. government agency and U.S. government-sponsored enterprise debt securities 287,503  255,863  2 % 287,687  257,654  2 % 100 % — % — % — % U.S. government agency and U.S. government-sponsored enterprise mortgage-backed securities (2) 11,282,319  11,095,099  79 % 10,544,278  10,397,991  79 % 100 % — % — % — % Municipal securities 275,348  237,959  1 % 277,275  243,102  2 % 100 % — % — % — % Non-agency mortgage-backed securities 629,132  548,367  4 % 667,195  584,735  4 % 97 % — % 3 % — % Corporate debt securities 535,158  447,583  3 % 554,158  464,981  4 % — % 40 % 56 % 4 % Foreign government bonds 249,263  240,395  2 % 247,249  238,455  2 % 46 % 54 % — % — % Asset-backed securities 30,965  30,430  0 % 31,886  31,389  0 % 29 % 18 % 53 % — % Total AFS debt securities $ 14,546,038   $ 14,093,483   100 % $ 13,619,781   $ 13,212,220   100 % 96 % 2 % 2 % 0 % HTM debt securities: U.S. Treasury securities $ 542,059  $ 526,048  21 % $ 540,666  $ 524,887  21 % 100 % — % — % — % U.S. government agency and U.S. government-sponsored enterprise debt securities 1,007,937  855,461  35 % 1,007,055  860,134  35 % 100 % — % — % — % U.S. government agency and U.S. government-sponsored enterprise mortgage-backed securities (3) 1,124,132  928,104  38 % 1,136,874  943,227  38 % 100 % — % — % — % Municipal securities 184,850  143,390  6 % 185,463  151,498  6 % 100 % — % — % — % Total HTM debt securities $ 2,858,978   $ 2,453,003   100 % $ 2,870,058   $ 2,479,746   100 % 100 % — % — % — % Total debt securities $ 17,405,016   $ 16,546,486   $ 16,489,839   $ 15,691,966   (1) Credit ratings represent independent assessments of the credit quality of debt securities. The Company determines the credit rating of a debt security based on the lowest rating assigned by any of the nationally recognized statistical rating organizations (“NRSROs”) that have rated the security.

The Company offers a wide variety of deposit products to meet the needs of its consumer and commercial customers. As a result, we believe our deposit base is seasoned, stable and well-diversified. Total deposits of $68.9 billion as of March 31, 2026 increased $1.8 billion or 3% from December 31, 2025, primarily due to growth in money market and noninterest-bearing demand deposits. The following table provides a breakdown of the Company’s deposits by segment and region as of March 31, 2026 and December 31, 2025: Change ($ in thousands) March 31, 2026 December 31, 2025 $ % Deposits by segment/region: Consumer and Business Banking - U.S. (1) $ 35,847,814  $ 34,494,368  $ 1,353,446  4  % Commercial Banking - U.S. (1) 24,829,606  24,115,647  (2) 713,959  3  % International Branches (3) 3,906,121  3,875,631  30,490  1  % Treasury and Other - U.S. (4) 4,336,014  4,597,055  (2) (261,041) (6) % Total deposits $ 68,919,555   $ 67,082,701   $ 1,836,854   3   % (1) Excludes deposits presented under International Branches. (2) Prior period balances have been reclassified for comparability due to a change in allocation methodology. (3) Deposits of our Hong Kong branch and China subsidiary bank branches are a subset of Commercial Banking segment deposits. (4) Treasury and Other segment deposits reflect wholesale, public funds, and brokered deposits, primarily managed by the Company’s Treasury department. 78 Customer deposit accounts in the U.S. offices are insured by the Federal Deposit Insurance Corporation (“FDIC”) for up to $250,000 per depositor, per ownership category. Management believes that presenting uninsured domestic deposits with an adjustment to exclude collateralized and affiliate deposits provides a more accurate view of the deposits at risk, given that collateralized deposits are secured, and affiliate deposits are not customer-facing and are eliminated in consolidation. The following table summarizes the Company’s uninsured domestic deposit balances reported on Schedule RC-O Memo, Item 2 of the Bank’s Call Report as of March 31, 2026 and December 31, 2025, after certain adjustments: ($ in thousands) March 31, 2026 December 31, 2025 Uninsured deposits, per regulatory requirements (1) $ 35,249,660  $ 33,431,037  Less: Collateralized deposits (4,436,099) (4,464,567) Affiliate deposits (65,579) (131,106) Uninsured deposits, excluding collateralized and affiliate deposits (a) $ 30,747,982   $ 28,835,364   Total domestic deposits per Call Report (b) $ 65,236,217   $ 63,460,378   Uninsured deposits, excluding collateralized and affiliate deposits, ratio (a)/(b) 47   % 45   % (1) Uninsured deposits, per regulatory requirements, represent the portion of deposit accounts in U.S. branches that exceed the FDIC insurance limit as reported on Schedule RC-O Memo, Item 2 of the Bank’s Call Report. Additional information regarding the impact of deposits on net interest income, with a comparison of average deposit balances and rates, is provided in Item 2. MD&A — Results of Operations — Net Interest Income in this Form 10-Q. See also the discussion of the impact of deposits on liquidity in Item 2. MD&A — Liquidity Risk Management in this Form 10-Q. Capital The Company maintains a strong capital base to support its anticipated asset growth, operating needs, and credit risk exposures, and to ensure that the Company and the Bank are in compliance with all regulatory capital guidelines. The Company engages in regular capital planning processes on at least an annual basis to optimize the use of available capital and to appropriately plan for future capital needs, allocating capital to existing and future business activities. Furthermore, the Company conducts capital stress tests as part of its capital planning process. The stress tests enable the Company to assess the impact of adverse changes in the economy and interest rates on its capital base. The Company’s stockholders’ equity increased $100 million or 1% from $8.9 billion as of December 31, 2025 to $9.0 billion as of March 31, 2026. The increase was primarily due to $358 million of net income, partially offset by $123 million from open-market common stock repurchases and tax withheld in the form of stock repurchases on vested restricted stock units, $111 million of cash dividends declared and $43 million of other comprehensive loss. For other factors that contributed to the changes in stockholders’ equity, refer to Item 1. Consolidated Financial Statements — Consolidated Statement of Changes in Stockholders’ Equit y in this Form 10-Q. On January 22, 2025, the Company’s Board of Directors authorized the repurchase of up to $300 million of East West common stock, which will remain valid through December 31, 2026. The Company repurchased $99 million and $85 million of its common stock during the first quarters of 2026 and 2025, respectively. As of March 31, 2026, $117 million of the share repurchase authorization remained available. The Company paid a cash dividend of $0.80 and $0.60 per share during the first quarters of 2026 and 2025, respectively. In April 2026, the Company’s Board of Directors declared a second quarter 2026 cash dividend of $0.80 per share. The dividend is payable on May 18, 2026, to stockholders of record as of May 4, 2026. 79 Regulatory Capital and Ratios The federal banking agencies have risk-based capital adequacy requirements intended to ensure that banking organizations maintain capital that is commensurate with the degree of risk associated with their operations. The Company and the Bank are each subject to these regulatory capital adequacy requirements. See Item 1. Business — Supervision and Regulation — Regulatory Capital Requirements in the Company’s 2025 Form 10-K for additional details. The following table presents the Company’s and the Bank’s capital ratios as of March 31, 2026 and December 31, 2025 under the Basel III Capital Rules, and those required by regulatory agencies for capital adequacy and well-capitalized classification purposes: Basel III Capital Rules March 31, 2026 December 31, 2025 Company Bank Company Bank Minimum Regulatory Requirements Minimum Regulatory Requirements including Capital Conservation Buffer Well-Capitalized Requirements Risk-based capital ratios: Common Equity Tier 1 (“CET1”) capital (1) 15.1 % 13.8 % 15.1 % 13.9 % 4.5 % 7.0 % 6.5 % Tier 1 capital (2) 15.1 % 13.8 % 15.1 % 13.9 % 6.0 % 8.5 % 8.0 % Total capital 16.4 % 15.1 % 16.4 % 15.1 % 8.0 % 10.5 % 10.0 % Tier 1 leverage (1) 11.0 % 10.0 % 10.9 % 10.0 % 4.0 % 4.0 % 5.0 % (1) CET1 capital and Tier 1 leverage well-capitalized requirements apply to the Bank only. There are no well-capitalized requirements on CET1 capital ratio or Tier 1 leverage ratio for bank holding companies. (2) Well-capitalized Tier 1 capital ratio requirements for the Company and the Bank are 6.0% and 8.0%, respectively. The Company is committed to maintaining strong capital levels to assure its investors, customers and regulators that the Company and the Bank are financially sound. As of both March 31, 2026 and December 31, 2025, the Company and the Bank continued to exceed all “well-capitalized” capital requirements and the minimum capital requirements under the Basel III Capital Rules. Total risk-weighted assets increased $799 million from December 31, 2025 to $58.6 billion as of March 31, 2026, primarily due to loan growth. Risk Management Overview In the normal course of business, the Company is exposed to a variety of risks, including risks inherent to the financial services industry and risks specific to the Company’s business. The Company operates under a Board-approved enterprise risk management (“ERM”) program. The Company’s ERM program outlines the company-wide approach to risk management and oversight, and describes the structures and practices employed to manage current and emerging risks inherent to the Company. The Company’s ERM program incorporates risk management throughout the organization in identifying, managing, monitoring, and reporting risks. It identifies the Company’s major risk categories as: credit, liquidity, market, operational, reputational, legal, compliance, Bank Secrecy Act/Anti-Money Laundering & Office of Foreign Assets Control, strategic, and technology risk. The Risk Oversight Committee (“ROC”) of the Board of Directors monitors the ERM program through such identified enterprise risk categories and provides oversight of the Company’s risk appetite and control environment. The ROC provides focused oversight of the Company’s identified enterprise risk categories on behalf of the full Board of Directors. Under the authority of the ROC, management committees apply targeted strategies to manage the risks to which the Company’s operations are exposed. 80 The Company’s ERM program is executed along the three lines of defense model, which provides for a consistent and standardized risk management control environment across the enterprise. The first line of defense is comprised of revenue generating, operational and support units. The second line of defense is comprised of risk management and control functions that provide independent risk oversight of first line activities and report to the Chief Risk Officer. The Chief Risk Officer reports to both the ROC and the Chief Executive Officer. The third line of defense is comprised of the Internal Audit and Independent Asset Review (“IAR”) functions. Internal Audit reports to the Chief Audit Executive (“CAE”), who reports to the Board’s Audit Committee. Internal Audit provides assurance and evaluates the effectiveness of risk management, control, and governance processes as established by the Company. IAR serves as an internal loan review and independent credit risk monitoring function within the Bank that works under the direction of the CAE and reports to the Audit Committee. IAR provides management and the Audit Committee with an objective and independent assessment of the Bank’s credit profile and credit risk management processes. Further discussion and analysis of selected primary risk areas are discussed in the following subsections of Risk Management. Credit Risk Management Credit risk is the risk that a borrower or counterparty will fail to perform in accordance with the terms and conditions of a loan, investment or derivative and expose the Company to loss. Credit risk exists with many of the Company’s assets and exposures such as loans, debt securities and certain derivatives. The majority of the Company’s credit risk is associated with lending activities. The ROC has primary oversight responsibility for the identified enterprise risk categories including credit risk. The ROC monitors management’s assessment of asset quality, credit risk trends, credit quality administration, underwriting standards, and portfolio credit risk management strategies and processes, such as diversification and liquidity, all of which enable management to control credit risk. At the management level, the Credit Risk Management Committee has primary oversight responsibility for credit risk. The Senior Credit Supervision function manages credit policy for the line of business transactional credit risk, assuring that all exposure is risk-rated according to the requirements of the credit risk rating policy. The Senior Credit Supervision function, in connection with the ERM function, also evaluates and reports the overall credit risk exposure to senior management and the ROC, including concentration limits and key risk indicators. Reporting directly to the Board’s Audit Committee, the IAR function provides additional validation support to the Company’s robust credit risk management culture by performing an independent and objective assessment of underwriting and documentation quality, and serves as an assurance function for the risk rating of the Company’s loan portfolios. A key focus of our credit risk management is adherence to a well-controlled underwriting and loan monitoring process. The Company assesses the overall performance and credit quality of the loans held-for-investment portfolio through an integrated analysis of specific performance ratios. This approach forms the basis of the discussion in the sections immediately following: Credit Quality, Nonperforming Assets and Allowance for Credit Losses. Credit Quality The Company utilizes a credit risk rating system to assist in monitoring credit quality. Loans are evaluated using the Company’s internal credit risk rating of 1 through 10. For more information on the Company’s credit quality indicators and internal credit risk ratings, refer to Note 6 — Loans Receivable and Allowance for Credit Losses to the Consolidated Financial Statements in this Form 10-Q. 81 The following table presents the Company’s criticized loans as of March 31, 2026 and December 31, 2025: Change ($ in thousands) March 31, 2026 December 31, 2025 $ % Criticized loans: Special mention loans $ 316,230  $ 344,876  $ (28,646) (8) % Classified loans (1) 913,386  796,273  117,113  15  % Total criticized loans (2) $ 1,229,616   $ 1,141,149   $ 88,467   8   % Special mention loans to loans held-for-investment 0.54  % 0.61  % Classified loans to loans held-for-investment 1.57  % 1.40  % Criticized loans to loans held-for-investment 2.12  % 2.01  % (1) Consists of substandard, doubtful and loss categories. (2) Excludes loans held-for-sale. Criticized loans increased $88 million or 8%, to $1.2 billion during the first quarter of 2026, primarily driven by increases in classified C&I and CRE loans, and special mention C&I loans, partially offset by a decrease in special mention CRE loans. Nonperforming Assets Nonperforming assets are comprised of nonaccrual loans, OREO and other nonperforming assets. Other nonperforming assets and OREO are repossessed assets and properties, respectively, acquired through foreclosure, or through full or partial satisfaction of loans held-for-investment. Nonperforming assets may also include nonperforming loans held-for-sale.

Collectability is generally assessed based on economic and business conditions, the borrower’s financial condition, and the adequacy of collateral, if any. For additional details regarding the Company’s nonaccrual loan policy, see Note 1 — Summary of Significant Accounting Policies — Significant Accounting Policies — Loans Held-for-Investment  to the Consolidated Financial Statements in the Company’s 2025 Form 10-K. Nonaccrual loans of $181 million as of March 31, 2026 increased $15 million or 9% from December 31, 2025, primarily due to higher residential mortgage and C&I nonaccrual loans, partially offset by C&I charge-offs, and transfers to OREO. As of March 31, 2026, $22 million or 12% of nonaccrual loans were less than 90 days delinquent. In comparison, $27 million or 16% of nonaccrual loans were less than 90 days delinquent as of December 31, 2025.

Allowance for Credit Losses The Company maintains its allowance for credit losses at a level it believes is sufficient to provide appropriate reserves to absorb estimated future credit losses in accordance with GAAP. For additional information on the policies, methodologies and judgments used to determine the allowance for credit losses, see Item 7. MD&A — Critical Accounting Estimates and Item 8.

Liquidity risk arises from the Company’s inability to meet its customer deposit withdrawals and obligations to other counterparties as they come due, or to obtain adequate funding at a reasonable cost to meet those obligations. Liquidity risk also considers the stability of deposits. The objective of liquidity management is to manage the potential mismatch of asset and liability cash flows. Maintaining an adequate level of liquidity depends on the institution’s ability to efficiently meet both expected and unexpected cash flow and collateral needs without adversely affecting daily operations or the financial condition of the institution. To achieve this objective, the Company analyzes its liquidity risk, maintains readily available liquid assets, and utilizes diverse funding sources including its stable core deposit base. 84 The ROC has primary oversight responsibility over liquidity risk management. At the management level, the Company’s Asset/Liability Committee (“ALCO”) establishes the liquidity guidelines that govern the day-to-day active management of the Company’s liquidity position by requiring sufficient asset-based liquidity to cover potential funding requirements and avoid over-dependence on volatile, less reliable funding markets. These guidelines are established and monitored for both the Bank and East West on a stand-alone basis to ensure that East West can serve as a source of strength for its subsidiaries. The ALCO regularly monitors the Company’s liquidity status and related management processes, and provides regular reports on the Company’s liquidity position relative to policy limits and guidelines to the Board of Directors. The Company believes its liquidity management practices have been effective under normal operating and stressed market conditions. The Company also maintains a contingency funding plan that utilizes early-warning indicators that are monitored to provide timely detection of adverse liquidity situations and enable management to promptly respond. The contingency funding plan describes the procedures, roles and responsibilities, and communication protocols for managing any identified emerging liquidity problem. Management monitors the early-warning indicators defined in the contingency funding plan, which include metrics for measuring the Company’s internal liquidity status as well as company-specific and market-wide external factors. When early warning indicators are triggered, management will evaluate the severity of the emerging liquidity problem and exercise appropriate management actions to address any liquidity and funding shortfalls. Liquidity Sources — Deposits. The Company’s primary source of funding is from deposits, generated by its banking business, which we believe is a relatively stable and low-cost source of funding. Our loans are funded by deposits, which amounted to $68.9 billion as of March 31, 2026, compared with $67.1 billion as of December 31, 2025. The Company’s loan-to-deposit ratio was 84% and 85% as of March 31, 2026 and December 31, 2025, respectively. See Item 2. — MD&A — Balance Sheet Analysis — Deposits in this Form 10-Q for further details related to the Company’s deposits. Other Liquidity Sources. In addition to deposits, the Company has access to various sources of wholesale financing, including borrowing capacity with the FHLB and Federal Reserve Bank (“FRB”) discount window, FRB Standing Repurchase Agreement Facility (“SRF”), and several master repurchase agreements with major brokerage companies to sustain an adequate liquid asset portfolio, meet daily cash demands and allow management flexibility to execute its business strategy. However, general financial market and economic conditions could impact our access to and cost of external funding. Additionally, the Company’s access to capital markets is affected by the Company’s own ratings received from various credit rating agencies. Sources of funding included $3.0 billion of FHLB advances as of both March 31, 2026 and December 31, 2025. As of March 31, 2026, the FHLB advances were comprised of $3.0 billion of term advances that had fixed and floating interest rates ranging from 3.78% to 3.95% with remaining maturities between 10 days and 1.3 years. As of March 31, 2026, the Company had $494 million in gross repurchase agreements, which matured on April 23, 2026. The Company did not have any repurchase agreements as of December 31, 2025. The Company also held long-term debt of $32 million in the form of junior subordinated debt as of both March 31, 2026 and December 31, 2025, which qualifies as Tier 2 capital for regulatory capital purposes. The Company has pledged loans and/or debt securities to the FHLB and the FRB discount window as collateral, as well as prepositioned unpledged debt securities as collateral for overnight repurchase agreements at the FRB SRF. The Company has established operational procedures to enable borrowing against these assets, including regular monitoring of the total pool of loans and debt securities eligible as collateral. Eligibility of collateral is defined in guidelines from the FHLB and FRB and is subject to change at their discretion. The Company operated within its established risk limits for liquidity measures as of March 31, 2026. Accordingly, the Company believes the cash and cash equivalents, and available collateralized borrowing capacity described below provide sufficient liquidity above its expected cash needs. 85 The Company maintains its sources of liquidity in the form of cash and cash equivalents, prepositioned and unpledged debt securities, and secured borrowing capacity with eligible loans and debt securities pledged as collateral. The following table presents the Company’s total available liquidity as of March 31, 2026 and December 31, 2025: Change ($ in thousands) March 31, 2026 December 31, 2025 $ % Cash and cash equivalents $ 4,438,870  $ 4,188,139  $ 250,731  6  % Interest-bearing deposits with banks 10,498  16,189  (5,691) (35) % Unused secured borrowing capacity from: FRB 14,040,968  13,235,104  805,864  6  % FHLB 11,685,898  11,849,692  (163,794) (1) % Fair value of prepositioned and unpledged securities Securities prepositioned for FRB SRF 6,920,861  4,822,741  2,098,120  44  % Other unpledged securities 5,046,207  6,659,487  (1,613,280) (24) % Total available liquidity $ 42,143,302   $ 40,771,352   $ 1,371,950   3   % The Company’s total available liquidity increased to $42.1 billion as of March 31, 2026, compared with $40.8 billion as of December 31, 2025. The increase in available liquidity was primarily due to an increase in loans pledged and growth of the securities portfolio. Cash Requirements. In the ordinary course of business, the Company enters into contractual obligations that require future cash payments, including funding for customer deposit withdrawals, repayments for short- and long-term borrowings, and other cash commitments. For additional information on these obligations, see Note 9 — Deposits to the Consolidated Financial Statements in the Company’s 2025 Form 10-K, and Note 7 — Affordable Housing Partnership, Tax Credit and Community Reinvestment Act Investments, Net and Note 8 — Federal Home Loan Bank Advances and Long-Term Debt to the Consolidated Financial Statements in this Form 10-Q. The Company also has off-balance sheet arrangements which represent transactions that are not recorded on the Consolidated Balance Sheet. The Company’s off-balance sheet arrangements include (1) commitments to extend credit, such as loan commitments, commercial letters of credit for foreign and domestic trade, standby letters of credit (“SBLCs”), and financial guarantees, to meet the financing needs of its customers, (2) future interest obligations related to customer deposits and the Company’s borrowings, and (3) transactions with unconsolidated entities that provide financing, liquidity, market risk or credit risk support to the Company, or engage in leasing, hedging or research and development services with the Company. A portion of these commitments are expected to expire unused or only partially used, therefore the total commitment amounts do not necessarily represent future cash requirements. The Company does not expect the total commitment amounts as of March 31, 2026 to have a material current or future impact on the Company’s financial conditions or results of operations. Additional information about the Company’s loan commitments, commercial letters of credit and SBLCs is provided in Note 9 — Commitments and Contingencies to the Consolidated Financial Statements in this Form 10-Q. The Consolidated Statement of Cash Flows in this Form 10-Q summarizes the Company’s sources and uses of cash by type of activity for the first quarters of 2026 and 2025. Excess cash generated by operating and investing activities may be used to repay outstanding debt or invest in liquid assets. Liquidity for East West. In addition to bank level liquidity management, the Company manages liquidity at the parent company level for various operating needs including payment of dividends, repurchases of common stock, principal and interest payments on its borrowings, acquisitions and additional investments in its subsidiaries. East West’s primary source of liquidity is from cash dividends distributed by its subsidiary, East West Bank. The Bank is subject to various statutory and regulatory restrictions on its ability to pay dividends as discussed in Item 1 . Business — Supervision and Regulation — Dividends and Other Transfers of Funds in the Company’s 2025 Form 10-K. East West held $675 million in cash and cash equivalents and balances due from the Bank as of March 31, 2026, and $664 million in cash and cash equivalents as of December 31, 2025. Management believes that East West has sufficient sources of liquidity to meet the projected cash obligations for the coming year. 86 Liquidity Stress Testing. The Company utilizes liquidity stress analysis to determine the appropriate amounts of liquidity to maintain at the Company, foreign subsidiary and foreign branch to meet contractual and contingent cash outflows under a range of scenarios. Scenario analyses include assumptions about significant changes in key funding sources, market triggers, potential uses of funding and economic conditions in certain countries. In addition, Company specific events are incorporated into the stress testing. Liquidity stress tests are conducted to identify potential mismatches between liquidity sources and uses over various time horizons and under a variety of stressed conditions. Given the range of potential stresses, the Company maintains contingency funding plans on a consolidated basis and for individual entities. As of March 31, 2026, the Company believes it has adequate liquidity resources to conduct operations and meet other needs in the ordinary course of business, and is not aware of any events that are reasonably likely to have a material adverse effect on its liquidity, capital resources or operations. For more details on how economic conditions may impact our liquidity, see Item 1A . Risk Factors in the Company’s 2025 Form 10-K. Market Risk Management Market risk refers to the risk of potential loss due to adverse movements in market risk factors, including interest rates, foreign exchange rates, commodity prices, and credit spreads. The Company is primarily exposed to interest rate risk through its core business activities of extending loans and acquiring deposits. There have been no significant changes in our risk management practices as described in Item 7 . MD&A — Market Risk Management in the Company’s 2025 Form 10-K. Interest Rate Risk Management Interest rate risk is the risk that market fluctuations in interest rates can have a negative impact on the Company’s earnings and capital stemming from mismatches in the Company’s asset and liability cash flows, which primarily arise from customer-related activities such as lending and deposit-taking. The Company is subject to interest rate risk because: • Assets and liabilities may mature or reprice at different times. If assets reprice faster than liabilities and interest rates are generally rising, earnings will initially increase; • Assets and liabilities may reprice at the same time but by different amounts; • Short- and long-term market interest rates may change by different amounts. For example, the shape of the yield curve may affect the yield of new loans and funding costs differently; • The remaining maturity of various assets or liabilities may shorten or lengthen as interest rates change. For example, if long-term mortgage interest rates increase sharply, mortgage-related products may pay down at a slower rate than anticipated, which could impact portfolio income and valuation; or • Interest rates may have a direct or indirect effect on loan demand, collateral values, mortgage origination volume, and the fair value of other financial instruments. The ALCO coordinates the overall management of the Company’s interest rate risk, meets regularly to review the Company’s open market positions and establishes policies to monitor and limit exposure to market risk. Interest rate risk management is carried out primarily through strategies involving the Company’s loan portfolio, debt securities portfolio, available funding channels and capital market activities. In addition, the Company’s policies permit the use of derivative instruments to assist in managing interest rate risk. The Company measures and monitors interest rate risk exposure through various risk management tools, which include a simulation model that performs monthly interest rate sensitivity analyses under multiple interest rate scenarios against a baseline. The simulation model incorporates the market’s forward rate expectations and the Company’s earning assets and liabilities. The Company uses a dynamic balance sheet, incorporating expected forward growth and/or deposit product mix shift to perform the interest rate sensitivity analyses. The simulated interest rate scenarios include an instantaneous parallel shift in the yield curve and a gradual parallel shift in the yield curve (“linear rate ramp”). In addition, the Company also performs simulations using other alternative interest rate scenarios, including various permutations of the yield curve flattening, steepening or inverting. The Company uses the results of these simulations to formulate and gauge strategies to achieve a desired risk profile within its capital and liquidity guidelines. 87 The Company’s net interest income volatility simulations are based on a dynamic balance sheet approach and market forward rates to better reflect the interest rate risk on the Company’s financial statements. The Company’s simulation scenarios use parallel shocks for both instantaneous and gradual net interest income simulations, as well as economic value of equity (“EVE”) simulations. These simulations conform with industry-standard scenario definitions and enhance interpretability and comparability. The net interest income simulation model is based on the maturity and repricing characteristics of the Company’s interest rate sensitive assets, liabilities, and related derivative contracts. This model also incorporates various assumptions, which management believes to be reasonable but may have a significant impact on the results. These key assumptions include the timing and magnitude of changes in interest rates, the yield curve evolution and shape, the correlation between various interest rate indices, financial instruments’ future repricing characteristics and spread relative to benchmark rates, and the effect of interest rate floors and caps. The modeled results are highly sensitive to deposit mix and deposit beta assumptions, which are derived from a regression analysis of the Company’s historical deposit data. Simulation results are highly dependent on modeled behaviors and input assumptions. To the extent that actual behaviors are different from the assumptions used in the models, there could be material changes to the interest rate sensitivity results. The key behavioral models impacting interest rate sensitivity simulations include deposit repricing, deposit balance forecasts, and mortgage prepayments. These models and assumptions are documented, supported, and periodically back-tested to assess the reasonableness and effectiveness. The Company also regularly monitors the sensitivity of the other important modeling assumptions, such as loan and security prepayments and early withdrawal on fixed-rate customer liabilities. The Company makes appropriate calibrations to the model as needed and continually validates the model, methodology and results. Changes to key model assumptions are reviewed by the Technical ALCO, a subcommittee of ALCO. Scenario results do not reflect strategies that management could employ to limit the impact of changing interest rate expectations. The simulation does not represent a forecast of the Company’s net interest income but is a tool utilized to assess the risk of the impact of changing market interest rates across a range of interest rate environments. The Company employs a variety of quantitative and qualitative approaches to capture historical deposit repricing and balance behaviors. These historical observations are performed at a granular level based on key product characteristics, including distinctions for brokered, public, and large commercial deposits, which are then combined with forward-looking market expectations and the competitive landscape to generate the deposit repricing and balance forecasting models. The Company uses these deposit repricing models to forecast deposit interest expense. The repricing models provide sufficient granularity to reflect key behavioral differences across product and customer types. The deposit beta, which defines the sensitivity of deposit rates to changes in the effective federal funds rate, is a key parameter of the deposit rate forecast. As of March 31, 2026, the Company assumed a weighted-average beta of approximately 50%. As loan and debt security prepayment assumptions are key components of the Company’s model, the Company incorporates third-party vendor models to forecast prepayment behavior on mortgage loans and securities, which have mortgage loans as underlying collateral. These third-party vendor models have access to more comprehensive industry-level data that captures specific borrower and collateral characteristics over a variety of interest rate cycles. The Company will periodically assess and adjust the vendor models when appropriate to include its own available observations and expectations. Twelve-Month Net Interest Income Simulation Net interest income simulation modeling measures interest rate risk through earnings volatility. The simulation projects the cash flow changes in interest rate sensitive assets and liabilities, expressed in terms of net interest income, over a specified time horizon for defined interest rate scenarios. Net interest income simulations provide insight into the impact of market rate changes on earnings, which help guide risk management decisions. The Company assesses interest rate risk by comparing the changes of net interest income in different interest rate scenarios. 88 The Company models various interest rate scenarios, including scenarios based on gradual ramped shifts in interest rates, and assesses the corresponding impacts. These interest rate scenarios provide insight to the Company’s underlying interest rate risk. The gradual rate ramp table below shows the net interest income volatility under a gradual parallel shift of the market implied forward rates, in even monthly increments over the first 12 months, with the full shift passed through to the forward rates thereafter. The results are based on a dynamic balance sheet with expected loan and deposit growth as of the date of the analysis. Net Interest Income Volatility Change in Interest Rates (in bps) March 31, 2026 December 31, 2025 +200 Gradual rate ramp 3.3  % 3.4  % +100 Gradual rate ramp 1.7  % 1.7  % -100 Gradual rate ramp (1.8) % (1.5) % -200 Gradual rate ramp (3.3) % (3.0) % As of March 31, 2026, the Company’s net interest income profile remains modestly asset-sensitive under gradual ramped shifts in interest rates, with a higher proportion of interest-earning assets repricing in the near term, compared to interest-bearing liabilities. This position is primarily driven by a significant volume of variable-rate loans indexed to Prime and Term Secured Overnight Financing Rate (“SOFR”). A declining rate environment could negatively impact the net interest income. However, this potential impact could be partially mitigated by several structural factors, including balance sheet growth and mix evolution, ongoing reinvestment of cash flows into assets at rates above legacy lower yielding instruments, and prevailing yield‑curve conditions. To reduce net interest income volatility, the Company has designated $4.3 billion in notional value of interest rate contracts as cash flow hedges, which are estimated to mitigate net interest income variability by approximately 1.19% of base net interest income for every 100 basis point change in interest rates. A portion of the Company’s interest-bearing deposit portfolio consists of non-maturity deposits that are not directly indexed to short-term rates but remain sensitive to rate changes. The Company actively manages deposit pricing and employs quantitative models to evaluate and forecast deposit behavior under various interest rate scenarios. Actual results may differ from modeled projections due to variations in earning asset growth and changes in deposit composition driven by customer preferences. Modeled outcomes are highly dependent on behavioral assumptions, including deposit mix shifts and customer rate sensitivity. Economic Value of Equity at Risk EVE is a cash flow calculation that takes the present value of all asset cash flows and subtracts the present value of all liability cash flows. This calculation is used for asset/liability management and measures changes in the present value of the Bank’s assets and liabilities due to changes in interest rates. The economic value approach provides a comparatively broader scope than the net interest income volatility approach since it represents the discounted present value of cash flows over the expected life of the instruments. Due to this longer horizon, EVE is useful to identify risks arising from repricing, prepayment and maturity gaps between assets and liabilities on the balance sheet, as well as from off-balance sheet derivative exposures, over their lifetime. This long-term economic perspective into the Company’s interest rate risk profile allows the Company to identify anticipated negative effects of interest rate fluctuations. However, the difference in time horizons can cause the EVE analysis to diverge from the shorter-term net interest income analysis presented above. Given the uncertainty of the magnitude, timing and direction of future interest rate movements, the shape of the yield curve, and potential changes to the balance sheet, actual results may vary from those predicted by the Company’s model. 89 The following table presents the Company’s EVE sensitivity related to an instantaneous parallel shift in market interest rates by 100 and 200 bps as of March 31, 2026 and December 31, 2025. EVE Volatility (1) Change in Interest Rates (in bps) March 31, 2026 December 31, 2025 +200 (13.8) % (14.1) % +100 (6.6) % (6.6) % -100 5.1  % 5.2  % -200 8.8  % 9.5  % (1) The percentage change represents net present value change of the balance sheet as of the analysis date versus various interest rate scenarios. As of March 31, 2026, the Company’s EVE is expected to decrease when interest rates rise. The EVE sensitivity represents a duration mismatch between fixed-rate assets versus fixed-rate liabilities where more fixed-rate assets are expected to produce more stable net interest income in the short term but may lead to decreases in net present value of future cash flows. Derivatives It is the Company’s policy not to speculate on the future direction of interest rates, foreign currency exchange rates and commodity prices. However, the Company periodically enters into derivative transactions in order to manage its exposure to market risk, primarily interest rate risk and foreign currency risk. The Company believes these derivative transactions, when properly structured and managed, provide a hedge against inherent risk in certain assets and liabilities or against risk in specific transactions. Hedging transactions may be implemented using a variety of derivative instruments such as swaps, forwards, options, and collars. The Company uses interest rate contracts to hedge the variability in interest received on certain floating-rate commercial loans. Prior to entering any hedge accounting activity, the Company analyzes the costs and benefits of the hedge in comparison to alternative strategies. The Company also repositions its hedging derivatives portfolio based on the current assessment of economic and financial conditions, including the interest rate and foreign currency environments, balance sheet composition and trends, and the relative mix of its cash and derivative positions. In addition, the Company enters into derivative transactions in order to accommodate its customers with their business needs or to assist customers with their risk management objectives, such as managing exposure to fluctuations in interest rates, foreign currencies and commodity prices. To economically hedge against the derivative contracts entered into with the Company’s customers, the Company enters into offsetting derivative contracts with third-party financial institutions, some of which are cleared through central clearing organizations. The exposures from derivative transactions are collateralized by cash and/or eligible securities based on limits as set forth in the respective agreements between the Company and counterparty financial institutions. The fair value changes of the derivative contracts traded with third-party financial institutions are expected to be largely offset by the fair value changes of the derivative transactions executed with customers throughout the terms of these contracts, except for the credit valuation adjustment component of the contracts and the spread variances between the customer derivatives and the offsetting financial counterparty positions. The Company also utilizes foreign exchange contracts that are not designated as hedging instruments to mitigate the economic effect of fluctuations in certain foreign currency on-balance sheet assets and liabilities and to meet funding needs in certain foreign currencies. 90 The Company is subject to credit risk associated with the counterparties to the derivative contracts. This counterparty credit risk is a multi-dimensional form of risk, affected by both the exposure and credit quality of the counterparty, both of which are sensitive to market-induced changes. The Company’s Credit Risk Management Committee provides oversight of credit risk, and the Company has guidelines in place to manage counterparty concentration, tenor limits, and collateral. The Company manages the credit risk of its derivative positions by diversifying its positions among various counterparties, by entering into legally enforceable master netting agreements, and by requiring collateral arrangements, where possible. The Company may also transfer counterparty credit risk related to interest rate swaps to third-party financial institutions through the use of credit risk participation agreements. Certain derivative contracts are required to be cleared through central clearing organizations to further mitigate counterparty credit risk, where variation margin is applied daily as settlement to the fair value of the derivative contracts. In addition, the Company incorporates credit valuation adjustments and other market standard methodologies to appropriately reflect the counterparty’s and the Company’s own nonperformance risk in the fair value measurement of its derivatives. As of March 31, 2026, the Company anticipates performance by all of its counterparties and has not incurred any related credit losses. The following tables summarize certain information on derivative instruments designated as accounting hedges and utilized by the Company in its management of interest rate risk as of March 31, 2026 and December 31, 2025: March 31, 2026 Weighted-average ($ in thousands) Notional Amount Fair Value Assets Fair Value Liabilities Fixed Rate Floating Rate (1) Remaining Term (in months) Cash flow hedges Derivative contracts hedging loans: Interest rate swaps - Receive fixed pay floating $ 4,000,000  $ 22,611  $ 5,319  5.66  % 5.59  % 25.6 Interest rate collars - Buy floor sell cap 250,000  —  —  Cap: 4.58% Floor: 1.50% 3.67  % 2.0 Total cash flow hedges $ 4,250,000   $ 22,611   $ 5,319   December 31, 2025 Weighted-average ($ in thousands) Notional Amount Fair Value Assets Fair Value Liabilities Fixed Rate Floating Rate (1) Remaining Term (in months) Cash flow hedges Derivative contracts hedging loans: Interest rate swaps - Receive fixed pay floating $ 4,000,000  $ 39,997  $ 139  5.66  % 5.71  % 28.6 Interest rate collars - Buy floor sell cap 250,000  —  —  Cap: 4.58% Floor: 1.50% 3.87  % 5.0 Total cash flow hedges $ 4,250,000   $ 39,997   $ 139   (1) Floating rates are indexed to SOFR or Prime.

Certain of these policies include critical accounting estimates, which are subject to valuation assumptions, subjective or complex judgments about matters that are inherently uncertain, and it is likely that materially different amounts could be reported under different assumptions and conditions. The Company has procedures and processes in place to facilitate making these judgments. The following accounting policies are critical to the Company’s Consolidated Financial Statements: • allowance for credit losses; • fair value estimates; • goodwill impairment; and • income taxes. For additional information on the Company’s critical accounting estimates involving significant judgments, see Item 7. MD&A — Critical Accounting Estimates in the Company’s 2025 Form 10-K. Reconciliation of GAAP to Non-GAAP Financial Measures To supplement the Company’s unaudited interim Consolidated Financial Statements presented in accordance with U.S. GAAP, the Company uses certain non-GAAP measures of financial performance. Non-GAAP financial measures are not prepared in accordance with, or as an alternative to U.S. GAAP. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance that either excludes or includes amounts, or is subject to adjustments that have such an effect, that are not normally excluded or included in the most directly comparable financial measure that is calculated and presented in accordance with U.S. GAAP. The non-GAAP financial measures that may be discussed in this Form 10-Q include but are not limited to ROATCE and tangible book value per share. Certain additional non-GAAP financial measures that are components of the foregoing non-GAAP financial measures are also set forth and reconciled in the table below. The Company believes these non-GAAP financial measures, when taken together with the corresponding U.S. GAAP financial measures, provide meaningful supplemental information regarding its performance and allow comparability to prior periods. These non-GAAP financial measures may be different from non-GAAP financial measures used by other companies, limiting their usefulness for comparison purposes. The following tables present the reconciliations of U.S. GAAP to non-GAAP financial measures for the periods presented: Three Months Ended March 31, ($ in thousands) 2026 2025 Net income (a) $ 357,796  $ 290,270  Add: Amortization of mortgage servicing assets 149  293  Tax effect of amortization adjustment (1) (42) (87) Tangible net income (non-GAAP) (b) $ 357,903   $ 290,476   Average stockholders’ equity (c) $ 9,047,373  $ 7,869,074  Less: Average goodwill (465,697) (465,697) Average mortgage servicing assets (4,025) (5,120) Average tangible book value (non-GAAP) (d) $ 8,577,651   $ 7,398,257   ROAE (2) (a)/(c) 16.04 % 14.96 % ROATCE (2) (non-GAAP) (b)/(d) 16.92 % 15.92 % 92 ($ and shares in thousands, except per share data) March 31, 2026 December 31, 2025 Stockholders’ equity (a) $ 8,999,435  $ 8,899,202  Less: Goodwill (465,697) (465,697) Mortgage servicing assets (3,978) (4,119) Tangible book value (non-GAAP) (b) $ 8,529,760   $ 8,429,386   Number of common shares at period-end (c) 136,979   137,579   Book value per share (a)/(c) $ 65.70   $ 64.68   Tangible book value per share (non-GAAP) (b)/(c) $ 62.27   $ 61.27   (1) Applied statutory tax rate of 28.02% and 29.73% for the three months ended March 31, 2026 and 2025, respectively.
