Table of Contents BANNER CORPORATION AND SUBSIDIARIES SELECTED NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS Note 1: BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES The accompanying unaudited condensed consolidated financial statements include the accounts of Banner Corporation (the Company or Banner), a bank holding company incorporated in the State of Washington and its wholly-owned subsidiary, Banner Bank (the Bank). These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (SEC). In preparing these financial statements, the Company has evaluated events and transactions subsequent to March 31, 2026, for potential recognition or disclosure. In the opinion of Management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. Certain information and note disclosures have been condensed or omitted pursuant to the rules and regulations of the SEC and the accounting standards for interim financial statements. All significant intercompany transactions and balances have been eliminated. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in the financial statements. Various elements of the Company’s accounting policies, by their nature, are inherently subject to estimation techniques, valuation assumptions and other subjective assessments. The information included in this Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 31, 2025. Interim results are not necessarily indicative of results for a full year or any other interim period. Note 2: ACCOUNTING STANDARDS RECENTLY ISSUED OR ADOPTED Interim Reporting: Narrow-Scope Improvements (Subtopic 270-10) In December 2025, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. The amendments in this ASU clarify the applicability of Topic 270, enhance the navigability of interim reporting requirements, and consolidate existing interim disclosure guidance. The amendments specify the form and content of interim financial statements, provide a comprehensive list of required interim disclosures, and introduce a disclosure principle requiring entities to disclose events occurring after the most recent annual reporting period that have a material impact on the entity. The ASU does not change the fundamental nature or scope of interim reporting requirements. This ASU is effective for all entities for interim periods within annual periods beginning after December 15, 2027, with early adoption permitted. The amendments may be applied either prospectively or retrospectively to any periods presented in the financial statements. The Company is currently evaluating this ASU but does not expect its adoption to have a material impact on the Company’s consolidated financial statements. Derivatives and Hedging: Hedge Accounting Improvements (Subtopic 815-20) In November 2025, the FASB issued ASU 2025-09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements. The amendments in this ASU are intended to clarify certain aspects of the guidance on hedge accounting and to address several incremental hedge accounting issues arising from the global reference rate reform initiative. The update clarifies and expands guidance in several areas, including allowing groups of forecasted transactions to be hedged based on “similar” rather than “shared” risk exposure, offering greater flexibility in applying cash flow hedges. Overall, the amendments respond to stakeholder concerns following ASU 2017‑12 and address complexities arising from global reference‑rate reform, ultimately facilitating the achievement and maintenance of hedge accounting for highly effective hedging relationships. This ASU is effective for all entities for annual reporting periods beginning after December 31, 2026, and interim reporting periods within those annual reporting periods. Early adoption is permitted on any date on or after the issuance of this ASU. The Company does not expect the adoption of this ASU to have a material impact on the Company’s consolidated financial statements. Financial Instruments—Credit Losses: Purchased Loans (Topic 310-10): In November 2025, the FASB issued ASU 2025-08, Financial Instruments—Credit Losses (Topic 326): Purchased Loans. The amendments in this ASU are intended to simplify and improve the accounting for acquired loans by expanding the use of the gross‑up approach, previously limited to purchased credit‑deteriorated (PCD) assets, to a new category of purchased seasoned loans, which encompasses certain acquired non‑PCD loans. Under this approach, entities recognize an allowance for expected credit losses at acquisition with a corresponding increase to the asset’s amortized cost basis, eliminating Day‑1 credit loss expense and promoting greater comparability across acquisitions. This change aims to enhance comparability, consistency, and better reflect the economics of acquiring financial assets. This ASU is effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. Early adoption is permitted in an interim or annual reporting period in which financial statements have not yet been issued or made available for issuance. This ASU will impact loans acquired in future periods following adoption. 10 Table of Contents Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The amendments in this ASU are intended to modernize the guidance for accounting software costs that are accounted for under Subtopic 350-40 and remove all references to prescriptive and sequential software development stages. This increases the operability of the cost recognition guidance by considering different methods of software development. The ASU requires that an entity begin capitalizing software costs when both of the following conditions have been met: management has authorized and committed to funding the software project; and it is probable that the project will be completed; and the software will be used to perform the function intended (referred to as the “probable-to-complete recognition threshold”). In addition, this ASU clarifies disclosure requirements for Internal-Use Software. This ASU is effective for all entities for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The amendments may be applied using the prospective method, the modified transition approach, or retrospectively. The Company does not expect this ASU to have a material impact on the Company’s consolidated financial statements. Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The amendments in the ASU require public companies to disclose, in the notes to financial statements, specified information about certain costs and expenses at each interim and annual reporting period. Specifically, they will be required to: • Disclose the amounts of (a) purchases of inventory; (b) employee compensation; (c) depreciation; (d) intangible asset amortization; and (e) depreciation, depletion, and amortization recognized as part of oil- and gas-producing activities (or other amounts of depletion expense) included in each relevant expense caption. • Include certain amounts that are already required to be disclosed under GAAP in the same disclosure as the other disaggregation requirements. • Disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. • Disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. The amendments should be applied prospectively. The Company does not expect this ASU to have a material impact on the Company’s consolidated financial statements.

Management does not believe that any remaining individual unrealized loss as of March 31, 2026 or December 31, 2025 resulted from credit loss. The decline in fair market value of these securities was generally due to changes in interest rates and changes in market-desired spreads subsequent to their purchase. There were no securities—available-for-sale in a nonaccrual status at March 31, 2026 or December 31, 2025. The following table presents gross gains and losses on sales and partial calls of securities available-for-sale (in thousands).

The Company’s non-rated held-to-maturity debt securities are primarily United States government sponsored enterprise debentures carrying minimal to no credit risk. The non-rated corporate bonds primarily consist of Community Reinvestment Act related bonds secured by loan instruments from low to moderate income borrowers. The remaining non-rated held-to-maturity debt securities balance is comprised of local municipal debt from within the Company’s geographic footprint and is monitored through quarterly or annual financial review. This municipal debt is predominately essential service or unlimited general obligation backed debt.

The system is a tool to evaluate portfolio asset quality throughout each applicable loan’s life as an asset of the Company. Generally, loans are risk rated on an aggregate borrower/relationship basis with individual loans sharing similar ratings. There are some instances when specific situations relating to individual loans will provide the basis for different risk ratings within the aggregate relationship. Loans are graded on a scale of 1 to 9. A description of the general characteristics of these categories is shown below. Overall Risk Rating Definitions : Risk-ratings contain both qualitative and quantitative measurements and take into account the financial strength of a borrower and the structure of the loan. Consequently, the definitions are to be applied in the context of each lending transaction and judgment must also be used to determine the appropriate risk rating, as it is not unusual for a loan to exhibit characteristics of more than one risk-rating category. Consideration for the final rating is centered in the borrower’s ability to repay, in a timely fashion, both principal and interest. The Company’s risk-rating and loan grading policies are reviewed and approved annually. There were no material changes in the risk-rating or loan grading system for the periods presented. Risk Ratings 1-5: Pass Credits with risk ratings of 1 to 5 meet the definition of a pass risk rating. The strength of credits varies within the pass risk ratings, ranging from a risk rated 1 being an exceptional credit to a risk rated 5 being an acceptable credit that requires a more than normal level of supervision. Risk Rating 6: Special Mention A credit with potential weaknesses that deserves Management’s close attention is risk rated a 6. If left uncorrected, these potential weaknesses will result in deterioration in the capacity to repay debt. A key distinction between Special Mention and Substandard is that in a Special Mention credit, there are identified weaknesses that pose potential risk(s) to the repayment sources, versus well defined weaknesses that pose risk(s) to the repayment sources. Assets in this category are expected to be in this category no more than 9-12 months as the potential weaknesses in the credit are resolved. Risk Rating 7: Substandard A credit with well-defined weaknesses that jeopardize the ability to repay in full is risk rated a 7. These credits are inadequately protected by either the sound net worth and payment capacity of the borrower or the value of pledged collateral. These are credits with a distinct possibility of loss. Loans headed for foreclosure and/or legal action due to deterioration are rated 7 or worse. Risk Rating 8: Doubtful A credit with an extremely high probability of loss is risk rated 8. These credits have all the same critical weaknesses that are found in a substandard loan; however, the weaknesses are elevated to the point that based upon current information, collection or liquidation in full is improbable. While some loss on doubtful credits is expected, pending events may make the amount and timing of any loss indeterminable. In these situations, taking the loss is inappropriate until the outcome of the pending event is clear. Risk Rating 9: Loss A credit that is considered to be currently uncollectible or of such little value that it is no longer a viable bank asset is risk rated 9. Losses should be taken in the accounting period in which the credit is determined to be uncollectible. Taking a loss does not mean that a credit has absolutely no recovery or salvage value but, rather, it is not practical or desirable to defer writing off the credit, even though partial recovery may occur in the future. 17 Table of Contents The following tables present the Company’s portfolio of risk-rated loans by class and by grade as of March 31, 2026 and December 31, 2025 (in thousands). In addition, the tables include the gross charge-offs for the three months ended March 31, 2026 and the year ended December 31, 2025. Revolving loans that are converted to term loans are treated as new originations in the tables below and are presented by year of origination. Term loans that are renewed or extended for periods longer than 90 days are presented as a new origination in the year of the most recent renewal or extension.

Goodwill represents the excess of the purchase consideration paid over the fair value of the assets acquired, net of the fair values of liabilities assumed in a business combination, and is not amortized but is reviewed at least annually for impairment. The Company has identified one reporting unit for the purpose of evaluating goodwill for impairment. The Company completed an assessment of qualitative factors as of December 31, 2025 and concluded that no further analysis was required as it was more likely than not that the fair value of the reporting unit exceeded the carrying value. CDI represents the value of transaction-related deposits and the value of the client relationships associated with the deposits. The Company amortizes CDI assets over their estimated useful lives and reviews them at least annually for events or circumstances that could impair their value. The following table summarizes the changes in the Company’s goodwill and other intangibles for the year ended December 31, 2025 and the three months ended March 31, 2026 (in thousands): Goodwill CDI Total Balance, December 31, 2024 $ 373,121 $ 3,058 $ 376,179 Amortization — ( 1,567 ) ( 1,567 ) Balance, December 31, 2025 373,121 1,491 374,612 Amortization — ( 256 ) ( 256 ) Balance, March 31, 2026 $ 373,121 $ 1,235 $ 374,356 The following table presents the estimated amortization expense with respect to CDI as of March 31, 2026, for the periods indicated (in thousands): Estimated Amortization Remainder of 2026 $ 648 2027 426 2028 126 2029 35 $ 1,235 Mortgage Servicing Rights: Mortgage and Small Business Administration (SBA) servicing rights are reported in other assets. SBA servicing rights are initially recorded and carried at fair value. Mortgage servicing rights are initially recognized at fair value and are amortized in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Mortgage servicing rights are subsequently evaluated for impairment based upon the fair value of the rights compared to the amortized cost (remaining unamortized initial fair value). If the fair value is less than the amortized cost, a valuation allowance is created through an impairment charge to servicing fee income. However, if the fair value is greater than the amortized cost, the amount above the amortized cost is not recognized in the carrying value. The unpaid principal balance of loans for which mortgage and SBA servicing rights have been recognized totaled $ 2.76 billion and $ 2.77 billion at March 31, 2026 and December 31, 2025, respectively. Custodial accounts maintained in connection with this servicing totaled $ 23.2 million and $ 13.1 million at March 31, 2026 and December 31, 2025, respectively. An analysis of the mortgage and SBA servicing rights for the three months ended March 31, 2026 and 2025 is presented below (in thousands): Three Months Ended March 31, 2026 2025 Balance, beginning of the period $ 12,602 $ 13,487 Additions—amounts capitalized 661 616 Additions—through purchase — 2 Amortization (1) ( 838 ) ( 769 ) Fair value adjustments (2) ( 13 ) 85 Balance, end of the period $ 12,412 $ 13,421 (1) Amortization of mortgage servicing rights is recorded as a reduction of loan servicing income within mortgage banking operations and any unamortized balance is fully amortized if the loan repays in full. (2) Fair value adjustments relate to SBA servicing rights. These adjustments are estimated based on an independent dealer analysis by discounting estimated net future cash flows from servicing SBA loans. 32 Table of Contents Note 6: DEPOSITS Deposits consisted of the following at March 31, 2026 and December 31, 2025 (in thousands): March 31, 2026 December 31, 2025 Non-interest-bearing accounts $ 4,532,639 $ 4,489,839 Interest-bearing checking 2,628,731 2,609,080 Regular savings accounts 3,859,530 3,723,922 Money market accounts 1,354,650 1,388,001 Total interest-bearing transaction and savings accounts 7,842,911 7,721,003 Certificates of deposit: Certificates of deposit greater than or equal to $250,000 514,860 528,102 Certificates of deposit less than $250,000 949,954 1,004,202 Total certificates of deposit 1,464,814 1,532,304 Total deposits $ 13,840,364 $ 13,743,146 Included in total deposits: Public fund transaction and savings accounts $ 384,622 $ 373,529 Public fund interest-bearing certificates 36,125 34,431 Total public deposits $ 420,747 $ 407,960 Total brokered certificates of deposit $ — $ 50,002 Scheduled maturities and weighted average interest rates of certificates of deposit at March 31, 2026, are as follows (dollars in thousands): March 31, 2026 Amount Weighted Average Rate Maturing in one year or less $ 1,417,897 3.12 % Maturing after one year through two years 32,395 2.01 Maturing after two years through three years 7,716 0.62 Maturing after three years through four years 2,090 0.87 Maturing after four years through five years 4,297 2.63 Maturing after five years 419 0.51 Total certificates of deposit $ 1,464,814 3.08 % 33 Table of Contents Note 7: FAIR VALUE OF FINANCIAL INSTRUMENTS The following table presents estimated fair values of the Company’s financial instruments as of March 31, 2026 and December 31, 2025, whether or not recognized or recorded in the Consolidated Statements of Financial Condition (dollars in thousands): March 31, 2026 December 31, 2025 Level Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value Assets: Cash and cash equivalents 1 $ 439,239 $ 439,239 $ 422,640 $ 422,640 Securities—available-for-sale 2 2,004,707 2,004,707 1,985,990 1,985,990 Securities—available-for-sale 3 30,314 30,314 30,271 30,271 Securities—held-to-maturity 2 938,636 786,740 955,459 808,965 Securities—held-to-maturity 3 5,052 5,023 5,737 5,703 Loans held for sale 2 33,778 33,845 42,902 43,062 Loans receivable, net 3 11,547,274 11,493,796 11,561,411 11,497,137 Equity securities 1 510 510 406 406 FHLB stock 3 9,809 9,809 16,476 16,476 Bank-owned life insurance 1 321,660 321,660 319,347 319,347 Mortgage servicing rights 3 11,321 36,095 11,498 34,862 SBA servicing rights 3 1,091 1,091 1,104 1,104 Investments in limited partnerships 3 15,881 15,881 15,566 15,566 Derivatives: Interest rate swaps 2 9,878 9,878 9,978 9,978 Interest rate lock and forward sales commitments 2,3 476 476 333 333 Liabilities: Demand, interest checking and money market accounts 2 8,516,020 8,516,020 8,486,920 8,486,920 Regular savings 2 3,859,530 3,859,530 3,723,922 3,723,922 Certificates of deposit 2 1,464,814 1,458,958 1,532,304 1,527,803 FHLB advances 2 — — 150,000 150,000 Other borrowings 2 115,723 115,723 107,715 107,715 Subordinated notes, net 2 — — — — Junior subordinated debentures 3 79,472 79,472 79,151 79,151 Derivatives: Interest rate swaps 2 19,509 19,509 19,207 19,207 Interest rate lock and forward sales commitments 2,3 85 85 151 151 Risk participation agreement 2 6 6 5 5 The Company measures and discloses certain assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (that is, not a forced liquidation or distressed sale). When measuring fair value, Management will maximize the use of observable inputs and minimize the use of unobservable inputs whenever possible. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s estimates for market assumptions. The estimated fair value amounts of financial instruments have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize at a future date. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. In addition, reasonable comparability between financial institutions may not be likely due to the wide range of permitted valuation techniques and numerous estimates that must be made given the absence of active secondary markets for many of the financial instruments. This lack of uniform valuation methodologies also introduces a greater degree of subjectivity to these estimated fair values. 34 Table of Contents Items Measured at Fair Value on a Recurring Basis: The following tables present financial assets and liabilities measured at fair value on a recurring basis and the level within the fair value hierarchy of the fair value measurements for those assets and liabilities as of March 31, 2026 and December 31, 2025 (in thousands): March 31, 2026 Level 1 Level 2 Level 3 Total Assets: Securities—available-for-sale U.S. Government and agency obligations $ — $ 9,084 $ — $ 9,084 Municipal bonds — 146,437 — 146,437 Corporate bonds — 97,306 30,314 127,620 Mortgage-backed or related securities — 1,550,815 — 1,550,815 Asset-backed securities — 201,065 — 201,065 — 2,004,707 30,314 2,035,021 Loans held for sale (1) — 25,215 — 25,215 Equity securities 510 — — 510 SBA servicing rights — — 1,091 1,091 Investment in limited partnerships — — 14,860 14,860 Derivatives Interest rate swaps — 9,878 — 9,878 Interest rate lock and forward sales commitments — 446 30 476 $ 510 $ 2,040,246 $ 46,295 $ 2,087,051 Liabilities: Junior subordinated debentures $ — $ — $ 79,472 $ 79,472 Derivatives Interest rate swaps — 19,509 — 19,509 Interest rate lock and forward sales commitments — — 85 85 Risk participation agreement — 6 — 6 $ — $ 19,515 $ 79,557 $ 99,072 35 Table of Contents December 31, 2025 Level 1 Level 2 Level 3 Total Assets: Securities—available-for-sale U.S. Government and agency obligations $ — $ 6,143 $ — $ 6,143 Municipal bonds — 143,457 — 143,457 Corporate bonds — 87,518 30,271 117,789 Mortgage-backed or related securities — 1,596,332 — 1,596,332 Asset-backed securities — 152,540 — 152,540 — 1,985,990 30,271 2,016,261 Loans held for sale (1) — 34,586 — 34,586 Equity securities 406 — — 406 SBA servicing rights — — 1,104 1,104 Investment in limited partnerships — — 14,545 14,545 Derivatives Interest rate swaps — 9,978 — 9,978 Interest rate lock and forward sales commitments — — 333 333 $ 406 $ 2,030,554 $ 46,253 $ 2,077,213 Liabilities: Junior subordinated debentures $ — $ — $ 79,151 $ 79,151 Derivatives Interest rate swaps — 19,207 — 19,207 Interest rate lock and forward sales commitments — 83 68 151 Risk participation agreement — 5 — 5 $ — $ 19,295 $ 79,219 $ 98,514 (1) The unpaid principal balance of residential mortgage loans held for sale carried at fair value on a recurring basis was $ 24.9 million and $ 33.6 million at March 31, 2026 and December 31, 2025, respectively. The following methods were used to estimate the fair value of each class of financial instruments above: Securities: The estimated fair values of investment securities and mortgage-backed securities are priced using current active market quotes, if available, which are considered Level 1 measurements. For most of the portfolio, matrix pricing based on the securities’ relationship to other benchmark quoted prices is used to establish the fair value. These measurements are considered Level 2. Due to the continued limited activity in the trust preferred markets that have limited the observability of market spreads for some of the Company’s trust preferred securities (TPS), Management has classified these securities, included in Corporate Bonds, as a Level 3 fair value measure. Management periodically reviews the pricing information received from third-party pricing services and tests those prices against other sources to validate the reported fair values. Loans Held for Sale: Fair values for residential mortgage loans held for sale are determined by comparing actual loan rates to current secondary market prices for similar loans. Equity Securities: Equity securities are invested in a publicly traded stock. The fair value of these securities is based on daily quoted market prices. Investments in Limited Partnerships: Fair values are estimated using the practical expedient method based on our ownership interest in partners’ capital to which a proportionate share of net assets is attributed, for each limited partnership. SBA Servicing Rights: Fair values are estimated based on an independent dealer analysis by discounting estimated net future cash flows from servicing. The evaluation utilizes assumptions market participants would use in determining fair value including prepayment speeds, delinquency and foreclosure rates, the discount rate, servicing costs, and the timing of cash flows. The SBA servicing portfolio is stratified by loan type and fair value estimates are adjusted based on the serviced loan interest rates versus current rates on new loan originations since the most recent independent analysis. 36 Table of Contents Junior Subordinated Debentures: The fair value of junior subordinated debentures is estimated using an income approach technique. The significant inputs included in the estimation of fair value are the credit risk adjusted spread and three month SOFR (Secured Overnight Financing Rate). The credit risk adjusted spread represents the nonperformance risk of the liability. The Company utilizes an external valuation firm to validate the reasonableness of the credit risk adjusted spread used to determine the fair value. The junior subordinated debentures are carried at fair value which represents the estimated amount that would be paid to transfer these liabilities in an orderly transaction among market participants. Due to inactivity in the trust preferred markets that have limited the observability of market spreads, Management has classified this as a Level 3 fair value measurement. Derivatives: Derivatives include interest rate swap agreements, interest rate lock commitments to originate loans held for sale, forward sales contracts to sell loans and securities related to mortgage banking activities and risk participation agreements. Fair values for these instruments, which generally change as a result of changes in the level of market interest rates, are estimated based on dealer quotes and secondary market sources. As the interest rate lock commitments use a pull-through rate that is considered an unobservable input, these derivatives are classified as a Level 3 fair value measurement. Off-Balance Sheet Items: Off-balance sheet financial instruments include unfunded commitments to extend credit, including standby letters of credit, and commitments to purchase investment securities. The fair value of these instruments is not considered to be material. Limitations: The fair value estimates presented herein are based on pertinent information available to Management as of March 31, 2026 and December 31, 2025. The factors used in the fair value estimates are subject to change subsequent to the dates the fair value estimates are completed, therefore, current estimates of fair value may differ significantly from the amounts presented herein. Assets and Liabilities Measured at Fair Value Using Significant Unobservable Inputs (Level 3): The following table provides a description of the valuation technique, unobservable inputs, and quantitative and qualitative information about the unobservable inputs for the Company’s assets and liabilities classified as Level 3 and measured at fair value on a recurring and non-recurring basis at March 31, 2026 and December 31, 2025: Weighted Average Rate or Range Financial Instruments Valuation Technique Unobservable Inputs March 31, 2026 December 31, 2025 Corporate bonds (TPS) Discounted cash flows Discount rate 6.94 % 6.91 % Junior subordinated debentures Discounted cash flows Discount rate 6.94 % 6.91 % Loans individually evaluated Collateral valuations Discount to appraised value 8.75 % to 10.00 % 0 % to 8.75 % Interest rate lock commitments Pricing model Pull-through rate 88.11 % 88.86 % SBA servicing rights Discounted cash flows Constant prepayment rate 18.08 % 18.14 % Trust preferred securities : Management believes that the credit risk-adjusted spread used to develop the discount rate utilized in the fair value measurement of TPS is indicative of the risk premium a willing market participant would require under current market conditions for instruments with similar contractual rates and terms and conditions and issuers with similar credit risk profiles and with similar expected probability of default. Management attributes the change in fair value of these instruments, compared to their par value, primarily to perceived general market adjustments to the risk premiums for these types of assets subsequent to their issuance. Junior subordinated debentures : Similar to the TPS discussed above, Management believes that the credit risk-adjusted spread utilized in the fair value measurement of the junior subordinated debentures is indicative of the risk premium a willing market participant would require under current market conditions for an issuer with Banner’s credit risk profile. Management attributes the change in fair value of the junior subordinated debentures, compared to their par value, primarily to perceived general market adjustments to the risk premiums for these types of liabilities subsequent to their issuance. Future contractions in the risk adjusted spread relative to the spread currently utilized to measure the Company’s junior subordinated debentures at fair value as of March 31, 2026, or the passage of time, will result in negative fair value adjustments. At March 31, 2026, the discount rate utilized was based on a credit spread of 326 basis points and three-month SOFR of 368 basis points. Interest rate lock commitments: The fair value of the interest rate lock commitments is based on secondary market sources adjusted for an estimated pull-through rate. The pull-through rate is based on historical loan closing rates for similar interest rate lock commitments. An increase or decrease in the pull-through rate would have a corresponding, positive or negative fair value adjustment. SBA servicing asset: The constant prepayment rate (CPR) is set based on industry data. An increase in the CPR would result in a negative fair value adjustment, where a decrease in CPR would result in a positive fair value adjustment. 37 Table of Contents The following tables provide a reconciliation of the assets and liabilities measured at fair value using significant unobservable inputs (Level 3) on a recurring basis during the three months ended March 31, 2026 and 2025 (in thousands): Three Months Ended March 31, 2026 Level 3 Fair Value Inputs TPS Securities Borrowings—Junior Subordinated Debentures Interest Rate Lock and Forward Sales Commitments Investments in Limited Partnerships SBA Servicing Asset Beginning balance $ 30,271 $ 79,151 $ 265 $ 14,545 $ 1,104 Net change recognized in earnings 87 — ( 320 ) 116 ( 13 ) Net change recognized in accumulated other comprehensive income (AOCI) ( 44 ) 321 — — — Purchases, issuances and settlements — — — 199 — Ending balance at March 31, 2026 $ 30,314 $ 79,472 $ ( 55 ) $ 14,860 $ 1,091 Three Months Ended March 31, 2025 Level 3 Fair Value Inputs TPS Borrowings—Junior Subordinated Debentures Interest Rate Lock and Forward Sales Commitments Investments in Limited Partnerships SBA Servicing Asset Beginning balance $ 25,685 $ 67,477 $ 108 $ 13,955 $ 869 Net change recognized in earnings 74 — 197 280 85 Net change recognized in AOCI ( 3 ) 234 — — — Purchases, issuances and settlements — — — 790 — Ending balance at March 31, 2025 $ 25,756 $ 67,711 $ 305 $ 15,025 $ 954 Interest income, dividends and amortization related to TPS are recorded as a component of interest income. Interest expense related to the junior subordinated debentures is measured based on contractual interest rates and reported in interest expense. The change in fair value of the junior subordinated debentures, which represents changes in instrument specific credit risk, and the change in fair value of TPS securities are recorded in other comprehensive income. The change in fair value of investments in limited partnerships and the SBA servicing asset are recorded as a component of non-interest income. The change in fair value of the interest rate lock and forward sales commitments are included in mortgage banking operations in non-interest income. Items Measured at Fair Value on a Non-recurring Basis: The following tables present financial assets and liabilities measured at fair value on a non-recurring basis and the level within the fair value hierarchy of the fair value measurements for those assets as of March 31, 2026 and December 31, 2025 (in thousands): March 31, 2026 Level 1 Level 2 Level 3 Total Loans individually evaluated $ — $ — $ 3,948 $ 3,948 Real estate owned (REO) — — 6,248 6,248 December 31, 2025 Level 1 Level 2 Level 3 Total Loans individually evaluated $ — $ — $ 5,607 $ 5,607 REO — — 5,578 5,578 38 Table of Contents Loans individually evaluated : Expected credit losses for loans evaluated individually are measured based on the present value of expected future cash flows discounted at the loan’s original effective interest rate or when the Bank determines that foreclosure is probable, the expected credit loss is measured based on the fair value of the collateral as of the reporting date, less estimated selling costs, as applicable. As a practical expedient, the Bank measures the expected credit loss for a loan using the fair value of the collateral, if repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the Bank’s assessment as of the reporting date. In both cases, if the fair value of the collateral is less than the amortized cost basis of the loan, the Bank will recognize an allowance as the difference between the fair value of the collateral, less costs to sell (if applicable) and the amortized cost basis of the loan. If the fair value of the collateral exceeds the amortized cost basis of the loan, any expected recovery added to the amortized cost basis will be limited to the amount previously charged-off. Subsequent changes in the expected credit losses for loans evaluated individually are included within the provision for credit losses in the same manner in which the expected credit loss initially was recognized or as a reduction in the provision that would otherwise be reported. REO : The Company records REO (acquired through a lending relationship) at fair value on a non-recurring basis. Fair value adjustments on REO are based on updated real estate appraisals which are based on current market conditions. All REO properties are recorded at the lower of the estimated fair value of the real estate, less expected selling costs, or the carrying amount of the defaulted loans. From time to time, non-recurring fair value adjustments to REO are recorded to reflect partial write-downs based on an observable market price or current appraised value of property. Banner considers any valuation inputs related to REO to be Level 3 inputs. The individual carrying values of these assets are reviewed for impairment at least annually and any additional impairment charges are expensed. Note 8: INCOME TAXES, DEFERRED TAXES, AND TAX CREDIT INVESTMENTS As of March 31, 2026, the Company had a net deferred tax asset of $ 128.3 million, compared to $ 127.6 million at December 31, 2025. In addition, the Company has estimated $ 2.0 million of unrecognized tax benefits related to uncertain tax positions. The Company recorded income tax expense of $ 12.8 million and $ 10.7 million for the three months ended March 31, 2026 and 2025, respectively, representing effective tax rates of 19.0 % and 19.1 %, respectively. The effective tax rates differed from the statutory rate principally due to the effects of tax-exempt income, certain tax credits, and tax benefits related to restricted stock vesting. Tax credit investments: The Company invests in low income housing tax credit funds that are designed to generate a return primarily through the realization of federal tax credits. The Company accounts for these investments by amortizing the cost of tax credit investments over the life of the investment using a proportional amortization method and this tax credit investment amortization expense is a component of the provision for income taxes. The current balance of these tax credit investments is included in other assets, while the unfunded commitments are included in accrued expenses and other liabilities on the Consolidated Statements of Financial Condition. The following table presents the balances of the Company’s tax credit investments and related unfunded commitments at March 31, 2026 and December 31, 2025 (in thousands): March 31, 2026 December 31, 2025 Tax Credit Investments: Total commitments $ 205,902 $ 215,688 Unfunded commitments 104,459 118,471 The following table presents other information related to the Company’s tax credit investments for the three months ended March 31, 2026 and 2025 (in thousands): Three Months Ended March 31, 2026 2025 Tax credits and other tax benefits recognized $ 5,532 $ 4,245 Tax credit amortization expense included in provision for income taxes 4,086 3,510 39 Table of Contents Note 9: CALCULATION OF WEIGHTED AVERAGE SHARES OUTSTANDING FOR EARNINGS PER SHARE (EPS) The following table reconciles basic to diluted weighted average shares outstanding used to calculate earnings per share data for the three months ended March 31, 2026 and 2025 (in thousands, except shares and per share data): Three Months Ended March 31, 2026 2025 Net income $ 54,716 $ 45,135 Basic weighted average shares outstanding 34,039,234 34,509,815 Dilutive effect of unvested restricted stock 215,353 268,872 Diluted weighted average shares outstanding 34,254,587 34,778,687 Earnings per common share Basic $ 1.61 $ 1.31 Diluted $ 1.60 $ 1.30 Note 10: STOCK-BASED COMPENSATION PLANS The Company operates the 2014 Omnibus Incentive Plan (the 2014 Plan), the 2018 Omnibus Incentive Plan (the 2018 Plan) and the 2023 Omnibus Incentive Plan (the 2023 Plan), all of which were approved by its shareholders. The purpose of these plans is to promote the success and enhance the value of the Company by providing a means for attracting and retaining highly skilled employees, officers and directors of the Company and linking their personal interests with those of the Company’s shareholders. Under these plans, the Company currently has outstanding awards of restricted stock shares and restricted stock units. The Company reserved 900,000 shares of its common stock for issuance under the 2014 Plan in connection with the exercise of awards. As of March 31, 2026, 583,024 restricted stock units have been granted under the 2014 Plan of which 92,175 restricted stock units were unvested. No further awards will be granted under the 2014 Plan. The Company reserved 900,000 shares of common stock for issuance under the 2018 Plan in connection with the exercise of awards. As of March 31, 2026, 892,720 restricted stock units have been granted under the 2018 Plan of which 181,409 restricted stock units were unvested. The Company reserved 625,000 shares of common stock for issuance under the 2023 Plan in connection with the exercise of awards. As of March 31, 2026, 7,720 restricted stock shares and 122,964 restricted stock units have been granted under the 2023 Plan of which 2,793 restricted stock shares and 112,147 restricted stock units were unvested. The expense associated with all restricted stock grants (including restricted stock shares and restricted stock units) was $ 2.7 million and $ 2.2 million for the three month periods ended March 31, 2026 and March 31, 2025, respectively. Unrecognized compensation expense for these awards as of March 31, 2026, was $ 11.2 million and will be recognized over a weighted average period of 11 months. Note 11: COMMITMENTS AND CONTINGENCIES Financial Instruments with Off-Balance Sheet Risk - The Company has financial instruments with off-balance-sheet risk generated in the normal course of business to meet the financing needs of its clients. These financial instruments include commitments to extend credit, commitments related to standby letters of credit, commitments to originate loans, commitments to sell loans, and commitments to buy or sell securities. These instruments involve, to varying degrees, elements of credit and interest rate risk similar to the risk involved in on-balance sheet items. Our exposure to credit loss in the event of nonperformance by the other party to the financial instrument from commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. We apply the same credit policies to these commitments and conditional obligations as we do to our on-balance sheet financial instruments. Outstanding commitments consisted of the following at the dates indicated (in thousands): Contract or Notional Amount March 31, 2026 December 31, 2025 Commitments to extend credit $ 4,005,841 $ 3,978,474 Standby letters of credit and financial guarantees 27,527 26,406 Risk participation agreements 40,647 41,191 Commitments to originate loans held for sale 64,788 39,895 Commitments to sell loans secured by one- to four-family residential properties 30,682 43,264 Commitments to sell securities related to mortgage banking activities 56,556 27,250 40 Table of Contents In addition to the commitments disclosed in the table above, the Company is also committed to funding the unfunded portion of its tax credit investments, as well as the remaining unfunded portion of its investments in limited partnerships. As of March 31, 2026 and December 31, 2025, the remaining outstanding commitments related to the unfunded tax credit investments and limited partnership investments were as follows (in thousands): Unfunded commitment balance for: March 31, 2026 December 31, 2025 Tax credit investments $ 104,459 $ 118,471 Limited partnerships investments $ 11,198 $ 11,398 Commitments to extend credit are agreements to lend to a client, as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Many of the commitments may expire without being drawn upon; therefore, the total commitment amounts do not necessarily represent future cash requirements. Each client’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if deemed necessary upon extension of credit, is based on Management’s credit evaluation of the client. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, and income producing commercial properties. The Company’s allowance for credit losses - unfunded loan commitments at March 31, 2026 and December 31, 2025 was $ 12.9 million and $ 15.0 million, respectively. Standby letters of credit are conditional commitments issued to guarantee a client’s performance or payment to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to clients. Under a risk participation agreement, the Bank guarantees the financial performance of a borrower on the participated portion of an interest rate swap on a loan. Interest rates on one- to four-family residential loan applications are typically rate locked (committed) to clients during the application stage for periods ranging from 30 to 60 days, the most typical period being 45 days. Traditionally, these loan applications with rate lock commitments have the pricing for the sale of these loans locked with various qualified investors under a best-efforts delivery program at or near the time the interest rate is locked with the client. The Bank then attempts to deliver these loans before their rate locks expire. This arrangement generally requires delivery of the loans prior to the expiration of the rate lock. Delays in funding the loans may require a lock extension. The cost of a lock extension is sometimes covered by the client and other times by the Bank. These lock extension costs have not had a material impact to the Company’s operations. For mandatory delivery commitments the Company enters into forward commitments at specific prices and settlement dates to deliver either: (1) residential mortgage loans for purchase by secondary market investors (i.e., Freddie Mac or Fannie Mae), or (2) mortgage-backed securities to broker/dealers. The purpose of these forward commitments is to offset the movement in interest rates between the execution of its residential mortgage rate lock commitments with borrowers and the sale of those loans to the secondary market investor. There were no counterparty default losses on forward contracts during the three months ended March 31, 2026 or March 31, 2025. Market risk with respect to forward contracts arises principally from changes in the value of contractual positions due to changes in interest rates. The Company limits its exposure to market risk by monitoring differences between commitments to clients and forward contracts with market investors and securities broker/dealers. In the event the Company has forward delivery contract commitments in excess of available mortgage loans, the transaction is completed by either paying or receiving a fee to or from the investor or broker/dealer equal to the increase or decrease in the market value of the forward contract. Changes in the value of rate lock commitments are recorded as assets and liabilities. In the normal course of business, the Company and/or its subsidiaries have various legal proceedings and other contingent matters outstanding. These proceedings and the associated legal claims are often contested and the outcome of individual matters is not always predictable. These claims and counterclaims typically arise during the course of collection efforts on problem loans or with respect to action to enforce liens on properties in which the Bank holds a security interest. Based upon the information known to Management, there were no legal proceedings, pending or threatened, that Management believes would have a material adverse effect on the results of operations or consolidated financial position at March 31, 2026. In connection with certain asset sales, the Bank typically makes representations and warranties about the underlying assets conforming to specified guidelines. If the underlying assets do not conform to the specifications, the Bank may have an obligation to repurchase the assets or indemnify the purchaser against any loss. The Bank believes that the potential for material loss under these arrangements is remote. Accordingly, the fair value of such obligations is not material. Note 12: DERIVATIVES AND HEDGING The Company is party to various derivative instruments that are used for asset and liability management and client financing needs. Derivative instruments are contracts between two or more parties that have a notional amount and an underlying variable, require no net investment and allow for the net settlement of positions. The notional amount serves as the basis for the payment provision of the contract and takes the form of units, such as shares or dollars. The underlying variable represents a specified interest rate, index, or other component. The interaction between the notional amount and the underlying variable determines the number of units to be exchanged between the parties and influences the market value of the derivative contract. The Company’s predominant derivative and hedging activities involve interest rate swaps related to certain term loans and forward sales contracts associated with mortgage banking activities. Generally, these instruments help the Company manage exposure to market risk and meet client financing needs. Market risk represents the possibility that economic value or net interest income will be adversely affected by fluctuations in external factors such as market-driven interest rates and prices or other economic factors. 41 Table of Contents As of March 31, 2026 and December 31, 2025, the notional values or contractual amounts and fair values of the Company’s derivatives were as follows (in thousands): Asset Derivatives Liability Derivatives March 31, 2026 December 31, 2025 March 31, 2026 December 31, 2025 Notional/ Contract Amount Fair Value Notional/ Contract Amount Fair Value Notional/ Contract Amount Fair Value Notional/ Contract Amount Fair Value Interest rate swaps $ 421,679 $ 19,490 $ 409,748 $ 19,185 $ 421,679 $ 19,509 $ 409,748 $ 19,207 Master netting agreements ( 9,612 ) ( 9,207 ) — — Net interest rate swaps 9,878 9,978 19,509 19,207 Risk participation agreements 525 — 583 — 40,122 6 40,607 5 Mortgage loan commitments 9,192 30 39,895 333 55,596 55 — — Forward sales contracts 69,483 446 28,405 — 9,192 30 33,793 151 Total $ 500,879 $ 10,354 $ 478,631 $ 10,311 $ 526,589 $ 19,600 $ 484,148 $ 19,363 The Company’s asset derivatives are included in other assets, while the liability derivatives are included in accrued expenses and other liabilities on the Consolidated Statements of Financial Condition. Interest Rate Swaps: The Bank offers an interest rate swap program for commercial loan clients that provides the client with a variable-rate loan and enters into an interest rate swap in which the client receives a variable-rate payment in exchange for a fixed-rate payment. The Bank offsets its risk exposure by entering into an offsetting interest rate swap with a dealer counterparty for the same notional amount and length of term as the client interest rate swap providing the dealer counterparty with a fixed-rate payment in exchange for a variable-rate payment. These swaps do not qualify as designated hedges; therefore, each swap is accounted for as a freestanding derivative. Risk Participation Agreements: In conjunction with the purchase or sale of participating interests in loans, the Company also participates in related swaps through risk participation agreements which are used to share in the credit risk associated with interest rate swaps on participated loans. The existing credit derivatives resulting from these participations are not designated as hedges as they are not used to manage interest rate risk in the Company’s assets or liabilities and are not speculative. Mortgage Loan Commitments: The Company sells originated one- to four-family residential loans into the secondary mortgage loan markets. During the period of loan origination and prior to the sale of the loans in the secondary market, the Company has exposure to movements in interest rates associated with written interest rate lock commitments with potential borrowers to originate one- to four-family residential loans that are intended to be sold and for closed one- to four-family residential loans held for sale for which fair value accounting has been elected, that are awaiting sale and delivery into the secondary market. The Company economically hedges the risk of changing interest rates associated with these one- to four-family residential loan commitments by entering into forward sales contracts to sell these loans or mortgage-backed securities to broker/dealers at specific prices and dates. Gains (losses) recognized in income within mortgage banking operations on non-designated hedging instruments for the three months ended March 31, 2026 and 2025, were as follows (in thousands): Three Months Ended March 31, 2026 2025 Mortgage loan commitments $ ( 290 ) $ 281 Forward sales contracts 568 ( 457 ) $ 278 $ ( 176 ) The Company is exposed to credit-related losses in the event of nonperformance by the counterparty to these agreements. Credit risk of the financial contract is controlled through the credit approval, limits, and monitoring procedures and Management does not expect the counterparties to fail their obligations. 42 Table of Contents In connection with the interest rate swaps between the Bank and the dealer counterparties, the agreements contain a provision where if the Bank fails to maintain its status as a well or adequately capitalized institution, then the counterparty could terminate the derivative positions and the Bank would be required to settle its obligations. Similarly, the Bank could be required to settle its obligations under certain of its agreements if specific regulatory events occur, such as a publicly issued prompt corrective action directive, cease and desist order, or a capital maintenance agreement that required the Bank to maintain a specific capital level. If the Bank had breached any of these provisions at March 31, 2026 or December 31, 2025, it could have been required to settle its obligations under the agreements at the termination value. As of March 31, 2026 and December 31, 2025, the Company had no obligations to dealer counterparties related to these agreements. The Company generally posts collateral against derivative liabilities in the form of cash, government agency-issued bonds, mortgage-backed securities, or commercial mortgage-backed securities. Collateral posted against derivative liabilities was $ 18.5 million and $ 17.4 million as of March 31, 2026 and December 31, 2025, respectively. The collateral posted included restricted cash of $ 17.6 million and $ 16.4 million as of March 31, 2026 and December 31, 2025, respectively. Derivative assets and liabilities are recorded at fair value on the balance sheet. Master netting agreements allow the Company to settle all derivative contracts held with a single counterparty on a net basis and to offset net derivative positions with related collateral where applicable. In addition, some interest rate swap derivatives between the Company and the dealer counterparties are cleared through central clearing houses. These clearing houses characterize the variation margin payments as settlements of the derivative’s market exposure and not as collateral. The variation margin is treated as an adjustment to our cash collateral, as well as a corresponding adjustment to our derivative asset or liability. The variation margin adjustment was a positive adjustment of $ 9.6 million and a positive adjustment of $ 9.2 million as of March 31, 2026 and December 31, 2025, respectively. The following tables present additional information related to the Company’s derivative contracts, by type of financial instrument, as of March 31, 2026 and December 31, 2025 (in thousands): March 31, 2026 Gross Amounts of Financial Instruments Not Offset in the Consolidated Statement of Financial Condition Gross Amounts Recognized Amounts offset in the Statement of Financial Condition Net Amounts in the Statement of Financial Condition Netting Adjustment Per Applicable Master Netting Agreements Fair Value of Financial Collateral in the Statement of Financial Condition Net Amount Derivative assets Interest rate swaps $ 19,490 $ ( 9,612 ) $ 9,878 $ — $ — $ 9,878 $ 19,490 $ ( 9,612 ) $ 9,878 $ — $ — $ 9,878 Derivative liabilities Interest rate swaps $ 19,509 $ — $ 19,509 $ — $ ( 16,901 ) $ 2,608 $ 19,509 $ — $ 19,509 $ — $ ( 16,901 ) $ 2,608 December 31, 2025 Gross Amounts of Financial Instruments Not Offset in the Consolidated Statement of Financial Condition Gross Amounts Recognized Amounts offset in the Statement of Financial Condition Net Amounts in the Statement of Financial Condition Netting Adjustment Per Applicable Master Netting Agreements Fair Value of Financial Collateral in the Statement of Financial Condition Net Amount Derivative assets Interest rate swaps $ 19,185 $ ( 9,207 ) $ 9,978 $ — $ — $ 9,978 $ 19,185 $ ( 9,207 ) $ 9,978 $ — $ — $ 9,978 Derivative liabilities Interest rate swaps $ 19,207 $ — $ 19,207 $ — $ ( 15,767 ) $ 3,440 $ 19,207 $ — $ 19,207 $ — $ ( 15,767 ) $ 3,440 43 Table of Contents Note 13: SEGMENT DISCLOSURES The Company is managed by legal entity, rather than by lines of business, and its activities are considered a single operating segment for financial reporting purposes. The Bank is engaged in the single line of business of community banking, which involves gathering deposits and originating loans in its primary market areas. The Bank manages its operations, allocates resources, and monitors and reports its financials as a single operating segment. Banner’s Chief Executive Officer is considered the Chief Operating Decision Maker (CODM). The CODM assesses performance based on net income that is reported on our Consolidated Statements of Operations. The measure of segment assets is reported on our Consolidated Statement of Financial Condition as total assets. The CODM uses consolidated net income as the primary measure to evaluate resource allocations. The CODM is regularly provided with our consolidated financial statements, specifically the statement of operations and the statement of cash flows, as well as expense and budget data. Note 14: SUBSEQUENT EVENT On April 30,2026, the Company entered into a definitive merger agreement to acquire Pacific Financial Corporation, the holding company for Bank of the Pacific, in an all stock transaction. Under the terms of the agreement, at the effective time of the merger, shareholders of Pacific Financial Corporation will receive 0.2633 shares of Banner Corporation common stock for each Pacific Financial Corporation common share they own. The transaction is expected to close in the third quarter of 2026 and is subject to closing conditions, including Pacific Financial shareholder and regulatory approvals. As the transaction has not closed as of the date these unaudited condensed consolidated financial statements were issued, the acquisition has not been reflected in the accompanying unaudited condensed consolidated financial statements. 44 Table of Contents
