Comparison of Financial Condition at March 31, 2026 and December 31, 2025

Total assets decreased $8.3 million, or 0.1%, with a balance of $11.0 billion at both March 31, 2026 and December 31, 2025. The decrease in total assets was primarily attributable to decreases in cash and cash equivalents of $63.9 million, debt securities held to maturity of $18.4 million, and loans receivable, net, of $33.9 million, partially offset by an increase in debt securities available for sale of $76.9 million, an increase in Federal Home Loan Bank and Federal Reserve Bank Stock of $18.3 million, and an increase in other real estate owned of $5.9 million, representing one non-performing construction loan transferred to other real estate owned in March 2026.

COLUMBIA FINANCIAL, INC. AND SUBSIDIARIES

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Cash and cash equivalents decreased $63.9 million, or 18.7%, to $276.9 million at March 31, 2026 from $340.8 million at December 31, 2025. The decrease was primarily attributable to purchases of securities of $138.2 million, the purchase of Federal Reserve Bank of New York Stock, the origination of loans receivable, and a decrease in total deposits of $72.1 million, partially offset by principal repayments on securities of $20.9 million, calls and maturities on securities of $54.9 million, repayments on loans receivable and an increase in borrowings of $60.0 million.

Debt securities available for sale increased $76.9 million, or 6.8%, to $1.2 billion at March 31, 2026 from $1.1 billion at December 31, 2025. The increase was attributable to purchases of securities of $138.2 million, consisting primarily of U.S. government obligations and mortgage-backed securities, partially offset by an increase in the gross unrealized loss on securities of $4.8 million, calls and maturities on securities of $40.0 million, and repayments on securities of $17.1 million.

Debt securities held to maturity decreased $18.4 million, or 4.6%, to $377.8 million at March 31, 2026 from $396.2 million at December 31, 2025. The decrease was primarily attributable to maturities on securities of $14.9 million and repayments on securities of $3.8 million.

Loans receivable, net, decreased $33.9 million, or 0.4%, with a balance of $8.2 billion at both March 31, 2026 and December 31, 2025. One-to-four family loans, multifamily loans, commercial real estate loans, commercial business loans, and home equity loans and advances decreased $14.7 million, $8.4 million, $40.3 million, $14.5 million, and $5.6 million, respectively, partially offset by an increase in construction loans of $51.3 million. The allowance for credit losses for loans increased $1.6 million to $68.8 million at March 31, 2026 from $67.2 million at December 31, 2025, primarily due to an increase in qualitative loss rates based on the evaluation of current and projected economic conditions.

Total liabilities decreased $21.3 million, or 0.2%, to $9.8 billion at March 31, 2026 from $9.9 billion at December 31, 2025. The decrease was primarily attributable to a decrease in total deposits of $72.1 million, or 0.9%, and a decrease in accrued expenses and other liabilities of $11.3 million, partially offset by an increase in borrowings of $60.0 million, or 5.1%. The decrease in total deposits primarily consisted of decreases in non-interest-bearing demand deposits, interest-bearing demand deposits and money market accounts of $9.4 million, $102.9 million, and $13.8 million, respectively, partially offset by increases in savings and club accounts and certificates of deposits of $1.6 million and $52.4 million, respectively. The decrease in interest-bearing demand deposits was mainly attributable to seasonal decreases in the balance of municipal deposits. The decrease in accrued expenses and other liabilities related to the payout of benefit related accrued expenses coupled with a decrease in outstanding checks. The $60.0 million increase in borrowings was driven by a net increase in short-term borrowings of $35.0 million, coupled with new long-term borrowings of $40.0 million, partially offset by repayments of $15.0 million in maturing long-term borrowings.

Total stockholders’ equity increased $13.0 million, or 1.1%, with a balance of $1.2 billion at both March 31, 2026 and December 31, 2025, primarily attributable to net income of $13.1 million.

Comparison of Results of Operations for the Three Months Ended March 31, 2026 and March 31, 2025

Net income of $13.1 million was recorded for the quarter ended March 31, 2026, an increase of $4.2 million, compared to net income of $8.9 million for the quarter ended March 31, 2025. The increase in net income was primarily attributable to a $10.1 million increase in net interest income, and a $2.0 million decrease in provision for credit losses, partially offset by a $1.7 million decrease in non-interest income, a $3.6 million increase in non-interest expense, and a $2.5 million increase in income tax expense.

Net interest income was $60.4 million for the quarter ended March 31, 2026, an increase of $10.1 million, or 20.0%, from $50.3 million for the quarter ended March 31, 2025. The increase in net interest income was primarily attributable to a $6.7 million increase in interest income and a $3.4 million decrease in interest expense on deposits and borrowings. The increase in interest income was primarily due to an increase in the average balance of loans and securities coupled with an increase in average yields on loans. The 75 basis point decrease in market interest rates during 2025 contributed to lower interest rates paid on new and repricing deposits and borrowings during the quarter ended March 31, 2026, but did not have as significant of an impact on the yields on interest-earning assets, which remained stable since December 31, 2025, as assets repriced at a slower pace. Prepayment penalties, which are included in interest income on loans, totaled $253,000 for the quarter ended March 31, 2026, compared to $257,000 for the quarter ended March 31, 2025.

The average yield on loans for the quarter ended March 31, 2026 increased 12 basis points to 5.01%, as compared to 4.89% for the quarter ended March 31, 2025. Interest income on

Item 7.     Management's Discussion and Analysis of Financial Condition and Results of Operations

The objective of this section is to help potential investors understand our views on our results of operations and financial condition. You should read this discussion in conjunction with the consolidated financial statements and notes to the consolidated financial statements that appear at the end of this report.

Executive Summary

Our primary source of pre-tax income is net interest income. Net interest income is the difference between the interest we earn on our loans and securities and the interest we pay on our deposits and borrowings. Changes in levels of interest rates as well as the balances of interest-earning assets and interest-bearing liabilities affect our net interest income.

A secondary source of income is non-interest income, which is revenue we receive from providing products and services. Traditionally, the majority of our non-interest income has come from service charges, loan fees, interchange income, gains (losses) on sales of loans and securities, revenue from mortgage servicing, income from bank-owned life insurance and fee income from title insurance, insurance agency and wealth management businesses.

The non-interest expense we incur in operating our business consists of compensation and employee benefits expenses, occupancy expenses; depreciation; amortization and maintenance expenses; data processing and software expenses and other miscellaneous expenses, such as loan expenses, advertising, insurance, professional fees and federal deposit insurance premiums. Our largest non-interest expense is compensation and employee benefits, which consist primarily of compensation and wages paid to our employees, payroll taxes, and expenses for health insurance, retirement plans and other employee benefits.

Our business results are impacted by the pace of economic growth and the level of market interest rates, and the difference between short-term and long-term rates. Competition among banks to secure new customers, loans and deposits has remained fierce, and interest rate spreads have again declined over the last few years. We continue to adhere to our prudent underwriting standards and are committed to originating quality loans. Additionally, we have maintained relatively low levels of non-performing assets, past due loans and charge-offs, through all economic environments.

December 2024 Balance Sheet Repositioning

As part of the Company’s strategy to improve future earnings and expand its net interest margin, in December 2024 the Company sold $352.3 million of debt securities available for sale. Proceeds from the sale were used to fund loan growth of $72.9 million, purchase $78.1 million of higher yielding debt securities and prepay $170.0 million of higher cost borrowings. The repositioning was immediately accretive to net interest income. The sale and prepayment resulted in a pre-tax loss of approximately $37.9 million. The repositioning was neutral to tangible book value per share as the unrealized loss with respect to the debt securities was already recognized in the Company’s stockholders’ equity through accumulated other comprehensive loss.

Critical Accounting Policies and Estimates

In the preparation of our consolidated financial statements, we have adopted various accounting policies that govern the application of U.S. generally accepted accounting principles (“GAAP”) and general practices within the banking industry. Our significant accounting policies are described in note 2 to the consolidated financial statements.

Certain accounting policies involve significant judgments and assumptions by us that have a material impact on the carrying value of certain assets and liabilities. We consider these accounting policies, which are discussed below, to be critical accounting policies. These assumptions, estimates and judgments we use can be influenced by a number of factors, including the general economic environment. Actual results could differ from these judgments and estimates under different conditions, resulting in a change that could have a material impact on the carrying values of our assets and liabilities and our results of operations.

Allowance for Credit Losses. The determination of the allowance for credit losses (“ACL”) on loans is considered a critical accounting estimate by management because of the high degree of judgment involved in determining qualitative loss factors, the subjectivity of the assumptions used, and the potential for changes in the forecasted economic environment. Although we believe we have established and maintained the ACL at appropriate levels, changes in reserves may be necessary if actual economic and other conditions differ substantially from the forecast used in estimating the ACL. See note 2 in the notes to our consolidated financial statements for a detailed discussion of our accounting policies and methodologies for establishing the allowance for credit losses. Additional information about our allowance for credit losses is also presented in note 7 to the audited consolidated financial statements.

Our ACL totaled $67.2 million and $60.0 million at December 31, 2025 and 2024, respectively. The increase in the allowance for credit losses was primarily due to an increase in outstanding balances of loans. The ACL components related to collectively evaluated loan reserves was $67.2 million and $60.0 million, respectively, at December 31, 2025 and 2024, under the Current Expected Credit Loss ("CECL") methodology. At both December 31, 2025 and 2024 we had $0 for individually analyzed loan reserves.

40

At December 31, 2025, management performed a hypothetical sensitivity analysis to understand the impact of a change in a key input on our ACL. If the U.S. unemployment rate had been increased from an average range of approximately 4.4% to 7.4% for the forecast period, and U.S. Gross Domestic Product ("GDP") decreased from an average range of approximately 2.2% to 1.2% for the forecast period, our ACL reserves would have been approximately $1.0 million higher. This sensitivity analysis includes the impact of quantitative components of our ACL. Changes in quantitative inputs and qualitative loss factors may not occur in the same direction or magnitude across all segments of our loan portfolio and deterioration in some quantitative inputs and qualitative loss factors may offset improvement in others. This sensitivity analysis does not represent a change to our expectations of the economic environment but provides a hypothetical result to assess the sensitivity of the ACL to a change in a key input. This sensitivity analysis does not incorporate changes to management’s judgment of qualitative loss factors.

If the four-quarter U.S. unemployment rate forecast had been 10.4% rather than an average of approximately 4.4%, our ACL would have been approximately $16.7 million higher. This sensitivity analysis includes the impact to the quantitative components of our ACL. Changes in quantitative inputs and qualitative loss factors may not occur in the same direction or magnitude across all segments of our loan portfolio and deterioration in some quantitative inputs and qualitative loss factors may offset improvement in others. This sensitivity analysis does not represent a change to our expectations of the economic environment but provides a hypothetical result to assess the sensitivity of the ACL to a change in a key input. This sensitivity analysis does not incorporate changes to management’s judgment of qualitative loss factors.

Most of our non-performing assets are collateral dependent loans which are written down to the fair value of the collateral less estimated costs to sell. We continue to assess the collateral of these loans and obtain updated appraisals on these loans on an annual basis. To the extent the property values decline, there could be additional losses on these non-performing assets, which may be material. Management considered these market conditions in deriving the estimated ACL. Should economic difficulties occur, the ultimate amount of loss could vary from our current estimate. For additional discussion related to the determination of the allowance for credit losses, see “Risk Management-Analysis and Determination of the Allowance for Credit Losses” and the notes to the consolidated financial statements.

Income Taxes. We are subject to the income tax laws of the various jurisdictions where we conduct business and estimate income tax expense based on amounts expected to be owed to these various tax jurisdictions. The estimated income tax expense (benefit) is reported in the Consolidated Statements of Income. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. We exercise significant judgment in evaluating the amount and timing of recognition of the resulting tax assets and liabilities. These judgments require us to make projections of future taxable income. The judgments and estimates we make in determining our deferred tax assets are inherently subjective and are reviewed on a continual basis as regulatory and business factors change.

Accrued or prepaid taxes represent the net estimated amount due to or to be received from tax jurisdictions either currently or in the future and are reported in other assets or other liabilities in our consolidated financial statements. We assess the appropriate tax treatment of transactions and filing positions after considering statutes, regulations, judicial precedent and other pertinent information and maintain tax accruals consistent with our evaluation. Changes in the estimate of accrued taxes occur periodically due to changes in tax rates, interpretations of tax laws, status of examinations by the tax authorities and newly enacted statutory, judicial and regulatory guidance that could impact the relative merits of tax positions. These changes, when they occur, impact accrued taxes and can materially affect our operating results. The Company identified no significant income tax uncertainties through the evaluation of its income tax positions as of December 31, 2025 and 2024. Therefore, the Company has no unrecognized income tax benefits as of those dates.

As of December 31, 2025 and 2024, we had a net deferred tax (liability) asset totaling $(15.3) million and $12.4 million, respectively. In accordance with Accounting Standards Codification (“ASC”) Topic 740 “Income Taxes,” we use the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is established when management is unable to conclude that it is more likely than not that it will realize deferred tax assets based on the nature and timing of these items. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income tax expense in the period enacted. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. We exercise significant judgment in evaluating the amount and timing of recognition of the resulting tax assets and liabilities. These judgments require us to make projections of future taxable income. The judgments and estimates we make in determining our deferred tax assets are inherently subjective and are reviewed on a regular basis as regulatory or business factors change. Any reduction in estimated future taxable income may require us to record a valuation allowance against our deferred tax assets. A valuation allowance that results in additional income tax expense in the period in which it is recognized would negatively affect earnings. Management believes, based on current facts, that it is more likely than not that there will be sufficient taxable income in future years to realize federal deferred tax assets. As of December 31, 2025 and 2024, no valuation allowance was deemed necessary for the deferred tax assets related to state net operating losses.

Post-retirement Benefits. We provide certain health care and life insurance benefits, along with split-dollar bank-owned life insurance ("BOLI") death benefits, to eligible retired employees. The cost of retiree health care and other benefits during the employees’ period of active service are accrued monthly. We account for benefits in accordance with ASC Topic 715 “Pension and

41

Other Post-retirement Benefits.” The guidance requires an employer to: (a) recognize in the statement of financial position the over funded or underfunded status of a defined benefit post-retirement plan measured as the difference between the fair value of plan assets and the benefit obligations; (b) measure a plan’s assets and its obligations that determine its funded status as of the end of the Company's fiscal year (with limited exceptions); and (c) recognize as a component of other comprehensive income (loss), net of tax, the actuarial gain and losses and the prior service costs and credits that arise during the period. These assets and liabilities and expenses are based upon actuarial assumptions including interest rates, rates of increase in compensation, expected rate of return on plan assets and the length of time we will have to provide those benefits. Actual results may differ from these assumptions. These assumptions are reviewed and updated at least annually, and management believes the estimates are reasonable.

Pending Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Topic ("ASU") 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40), which requires disaggregated information about certain income statement line items in a tabular format in the notes to the consolidated financial statements. This update is effective for financial statements issued for fiscal years beginning after December 15, 2026, with early adoption in the interim period permitted. The Company is currently evaluating the impact of the adoption of this ASU on its consolidated financial statements. As it is only disclosure related, this ASU is not expected to have a significant impact on the consolidated financial statements.

In November 2025, the FASB issued ASU 2025-08, Financial Instruments-Credit Losses (Topic 326): Purchased Loans, which amends the guidance in ASC 326 on the accounting for certain purchased loans. Under the ASU, entities must account for acquired loans (excluding credit cards) that meet certain criteria at acquisition (“purchased seasoned loans”) by recognizing them at their purchase price plus an allowance for expected credit losses (i.e., the so-called gross-up approach). The ASU’s amendments align the accounting for purchased seasoned loans with the treatment of financial assets purchased with more-than-insignificant credit deterioration since origination (“PCD assets”). The amendments apply prospectively and will be effective for fiscal periods beginning after December 15, 2026 (and interim periods within). Early adoption is permitted. The Company is currently evaluating the impact of the adoption of the ASU on its consolidated financial statements, but does not expect it to have a significant impact.

Comparison of Financial Condition at December 31, 2025 and 2024

General

Total assets increased $543.3 million, or 5.2%, to $11.0 billion at December 31, 2025 from $10.5 billion at December 31, 2024. The increase in total assets was primarily attributable to increases in cash and cash equivalents of $51.6 million, debt securities available for sale of $96.1 million, loans receivable, net of $367.8 million, bank-owned life insurance of $8.2 million, and other assets of $11.6 million. The increase in cash and cash equivalents was primarily attributable to proceeds from principal repayments on securities of $164.0 million, sales, calls, and maturities on securities of $97.9 million, repayments on loans receivable, an increase in total deposits of $347.9 million and an increase in borrowings of $102.9 million, partially offset by the purchases of securities of $305.5 million, the origination and purchases of loans receivable and repurchases of common stock under our stock repurchase program of $13.4 million. The increase in debt securities available for sale was primarily attributable to purchases of securities of $272.1 million, consisting primarily of U.S. government obligations and mortgage-backed securities, and a decrease in the gross unrealized loss on securities of $37.5 million, partially offset by maturities on securities of $77.5 million, repayments on securities of $132.6 million, and the sale of securities of $15.7 million. The increase in loans receivable, net was primarily attributable to an increase in multifamily real estate loans, commercial real estate loans, and commercial business loans of $217.0 million, $173.4 million, and $144.8 million, respectively, partially offset by decreases in one-to-four family real estate loans, construction loans and home equity loans and advances of $152.7 million, $4.1 million and $3.9 million, respectively. The increase in commercial business loans was primarily due to the purchase of $130.9 million in equipment finance loans from a third party in May 2025, at a $3.2 million discount, which included $5.1 million of purchased credit deteriorated ("PCD") loans. The principal balance of the PCD loans purchased was charged-off by $3.2 million. The allowance for credit losses for loans increased $7.2 million to $67.2 million at December 31, 2025 from $60.0 million at December 31, 2024. During the year ended December 31, 2025, the increase in the allowance for credit losses for loans was primarily due to an increase in outstanding loan balances. The increase in bank-owned life insurance is attributable to income recognized on split dollar life insurance arrangements. The increase in other assets is primarily attributable to an increase in the Company's pension plan balance, as the return on plan assets outpaced the growth in the plan's obligation.

Total liabilities increased $462.9 million, or 4.9%, to $9.9 billion at December 31, 2025 from $9.4 billion at December 31, 2024. The increase was primarily attributable to an increase in total deposits of $347.9 million, or 4.3%, an increase in borrowings of $102.9 million, or 9.5%, and an increase in other liabilities of $11.8 million, or 6.8%. The increase in total deposits primarily consisted of increases in non-interest-bearing demand deposits, money market accounts and certificates of deposit of $79.4 million, $223.3 million and $109.7 million, respectively, partially offset by decreases in interest-bearing demand and savings and club accounts of $35.4 million and $29.1 million, respectively. The increase in borrowings was driven by a net increase in short-term borrowings of $32.0 million, coupled with new long-term borrowings of $175.3 million, partially offset by repayments of $104.4 million in maturing long-term borrowings. The increase in other liabilities was primarily related to increases in accrued expenses and benefit plan related liabilities coupled with an increase in outstanding checks.

42

Total stockholders’ equity increased $80.4 million, or 7.4%, to $1.2 billion at December 31, 2025 from $1.1 billion at December 31, 2024. The increase in total stockholders’ equity was primarily attributable to net income of $51.8 million, an increase of $34.4 million in other comprehensive income, which includes changes in unrealized losses on debt securities available for sale and unrealized gains on swap contracts, net of taxes, included in other comprehensive income, and the recognition of $4.7 million in stock based compensation expense. These increases were partially offset by the repurchase of 873,304 shares of common stock at a cost of approximately $13.4 million, or $15.29 per share, under our stock repurchase program.

Securities

As part of the Company’s strategy to improve future earnings and expand its net interest margin, in December 2024 the Company sold $352.3 million of debt securities available for sale. Proceeds from the sale were used to fund loan growth of $72.9 million, purchase $78.1 million of higher yielding debt securities and prepay $170 million of higher cost borrowings. The repositioning was immediately accretive to net interest income. The sale and prepayment resulted in a pre-tax loss of approximately $37.9 million. The repositioning was neutral to tangible book value per share as the unrealized loss with respect to the debt securities was already recognized in the Company’s stockholders’ equity through accumulated other comprehensive loss.

Debt securities available for sale and held to maturity increased $99.5 million, or 7.0%, to $1.5 billion at December 31, 2025 from $1.4 billion at December 31, 2024. The increase in securities during 2025 was primarily attributable to purchases of securities of $305.5 million, a decrease in gross unrealized losses of $37.5 million, and $13.3 million of Freddie Mac mortgage participation certificates exchanged, partially offset by repayments received of $164.0 million, sales of securities of $15.6 million, and maturities and calls of securities $81.5 million. We continue to focus on maintaining a high quality securities portfolio that provides consistent cash flows in changing interest rate environments. At December 31, 2025, our total securities portfolio, which includes equity securities, was 13.8% of total assets, as compared to 13.6% at December 31, 2024.

At December 31, 2025, 58.4% of the debt securities available for sale portfolio was comprised of mortgage-backed securities and CMOs issued by Freddie Mac, Fannie Mae and Ginnie Mae. These securities are guaranteed by the issuing agency and backed by residential and multifamily mortgages. These securities are comprised of fixed rate, adjustable-rate and hybrid securities that bear a fixed rate for a specific term and thereafter, to the extent they are not prepaid, adjust periodically. At December 31, 2025, U.S. government and agency obligations comprised the next largest segment of the available for sale portfolio, totaling 35.5%. At December 31, 2025, the remainder of our available for sale securities portfolio consisted of corporate debt securities and municipal obligations which comprised 5.9% and 0.2%, respectively.

At December 31, 2025, 88.7% of the debt securities held to maturity portfolio was comprised of mortgage-backed securities and CMOs issued by Freddie Mac, Fannie Mae and Ginnie Mae. These securities are guaranteed by the issuing agency and backed by residential and multifamily mortgages. These securities are comprised of fixed rate, adjustable-rate and hybrid securities that bear a fixed rate for a specific term and thereafter, to the extent they are not prepaid, adjust periodically. At December 31, 2025, the remaining 11.3% of our held to maturity securities portfolio consisted of U.S. government and agency obligations.

To mitigate the credit risk related to our securities portfolio, we primarily invest in agency and highly-rated securities. As of December 31, 2025, approximately 95.1% of the total portfolio consisted of direct government obligations or government sponsored enterprise obligations, approximately 4.5% of the remaining portfolio was rated at least investment grade and approximately 0.4% of the remaining portfolio was not rated. Securities not rated consist primarily of private placement municipal notes issued and/or guaranteed by local municipal authorities and equity securities.

    At December 31, 2025 and 2024, securities with carrying values of $880.1 million and $1.1 billion, respectively, were in net unrealized loss positions that totaled $114.4 million and $159.7 million, respectively. The decrease in unrealized losses on securities in 2025 was primarily due to the sales of lower yielding securities as discussed above, and changes in market interest rates.

For available for sale securities, the Company assesses whether a loss is from credit or other factors and considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost, a credit loss would be recorded through an allowance for credit losses, limited by the amount that the fair value is less than the amortized cost basis. We believe that unrealized and unrecognized losses on securities at December 31, 2025 and 2024 are a function of changes in market interest rates and credit spreads, not changes in credit quality. Therefore, no allowance for credit losses was recorded at December 31, 2025 and 2024.

For held to maturity securities, management measures expected credit losses on a collective basis by major security type. All of the mortgage-backed securities are issued by U.S. government agencies and are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses and, therefore, the expectation of non-payment is zero and the Company is not required to estimate an allowance for credit losses on these securities under the CECL standard. All these securities reflect a credit quality rating of AAA by Moody's Investors Service.

At December 31, 2025 and 2024, we had no securities in a single company or entity (other than United States Government and United States GSE securities) that had an aggregate book value in excess of 5% of our equity.

The following tables set forth the stated maturities and weighted average yields of securities at December 31, 2025. Certain securities have adjustable interest rates and will reprice monthly, quarterly, semi-annually or annually within the various maturity ranges. Weighted average yields for tax-exempt securities totaling $2.0 million with a weighted average rate of 3.02%, are presented on a tax equivalent basis using a federal marginal tax rate of 21%.

44

Equity securities are not included in the table based on lack of a maturity date. The tables present contractual final maturities for mortgage-backed securities and does not reflect repricing or the effect of prepayments.

Deposits

Our primary source of funds is our deposits, which are comprised of non-interest-bearing and interest-bearing transaction accounts, money market deposit accounts, savings and club deposits and certificates of deposit.

Deposits increased $347.9 million, or 4.3%, to $8.4 billion at December 31, 2025 from $8.1 billion at December 31, 2024. The increase in balances of non-interest-bearing demand, money market accounts and certificates of deposit was heavily attributed to a shift in balances from savings and club deposits as well as new deposits attained. Columbia Bank has priced select certificates of deposit accounts very competitively to the market, but there continues to be strong competition for funds from other banks and non-bank investment products. Municipal deposits totaled $979.7 million at December 31, 2025, compared to $969.4 million at December 31, 2024. We continue our efforts to emphasize deposit taking through various channels, including brokered deposits and reciprocal deposit arrangements with third parties.

During 2025, non-interest-bearing demand accounts increased $79.4 million, interest-bearing demand accounts decreased $35.4 million, money market accounts increased $223.3 million, savings and club deposits decreased $29.1 million, and certificates of deposits increased $109.7 million. We have focused on obtaining deposit products by offering attractive pricing and promotions, expanding our product lines and by deepening our existing customer relationships.

Borrowings

We have the ability to utilize advances and overnight lines of credit from the FHLBNY to supplement our liquidity. As a member bank, we are required to own capital stock in the FHLBNY and are authorized to apply for advances on the security of such stock and certain mortgage loans and other assets, provided certain standards related to creditworthiness have been met. Advances are made under several different programs, each having its own interest rate and range of maturities. We can also utilize securities sold under agreements to repurchase to provide funding. We maintain access to the Federal Reserve discount window and federal funds lines with correspondent banks for additional contingency funding. To secure our borrowings, we generally pledge securities and/or loans. The types of securities pledged for borrowings include, but are not limited to, government-sponsored enterprises ("GSE") including notes and government agency mortgage-backed securities and CMOs. The types of loans pledged for borrowings include, but are not limited to, one-to-four family real estate loans home equity loans and multifamily and commercial real estate loans.

Results of Operations for the Year Ended December 31, 2025

    Financial Highlights

Net income of $51.8 million was recorded for the year ended December 31, 2025, an increase of $63.4 million, as compared to a net loss of $11.7 million for the year ended December 31, 2024. The increase was primarily attributable to an increase in net interest income of $43.7 million, a decrease in provision for credit losses of $4.6 million, and an increase in non-interest income of $35.2 million, partially offset by an increase in income tax expense of $20.5 million. In 2025, the increase in net interest income was primarily attributable to an increase in total interest income of $19.5 million and a decrease in total interest expense of $24.1 million.

A provision for credit losses of $9.8 million was recorded for the year ended December 31, 2025, a decrease of $4.6 million, as compared to $14.5 million for the year ended December 31, 2024. The decrease in provision for credit losses was primarily attributable to a decrease in net charge-offs, which totaled $5.8 million for the year ended December 31, 2025 as compared to $9.6 million for the year ended December 31, 2024, and a decrease in quantitative loss rates based on the evaluation of current and projected economic conditions, partially offset by an increase in outstanding loan balances.

Non-interest income of $37.1 million was recorded for the year ended December 31, 2025, an increase of $35.2 million, as compared to $1.9 million for the year ended December 31, 2024. The increase was primarily attributable to an increase in the (loss) gain on securities transactions of $36.1 million which included a $34.6 million loss in the 2024 period resulting from the balance sheet repositioning transaction, an increase of $1.5 million in demand deposit account fees mainly related to commercial treasury services, and an increase of $1.4 million in loan fees and service charges related to customer swap income, partially offset by a decrease in the change in fair value of equity securities of $1.7 million, and a decrease of $3.9 million in other non-interest income, mainly related to interest rate swaps. The $1.7 million decrease in the change in fair value of equity securities included the sale of a portion of Freddie Mac and Fannie Mae preferred stock included in equity securities.

Non-interest expense of $180.9 million was recorded for the year ended December 31, 2025, a decrease of $443,000, as compared to $181.3 million for the year ended December 31, 2024. The decrease was primarily attributable to a $3.4 million decrease in professional fees for legal, regulatory and compliance-related costs, a decrease in merger-related expenses of $1.5 million, a decrease in loss on extinguishment of debt of $3.4 million resulting from the 2024 balance sheet repositioning transaction, and a decrease in other non-interest expense of $3.5 million, mainly related to interest rate swaps, partially offset by an increase in compensation and employee benefits expense of $9.7 million and an increase in data processing and software expenses of $1.6 million. The increase in compensation and employee benefits expense was mainly due to an increase in employee incentive compensation and normal annual increases.

Income tax expense of $16.2 million was recorded for the year ended December 31, 2025, an increase of $20.5 million, as compared to a tax benefit of $4.3 million for the year ended December 31, 2024. The increase was mainly due to an increase in pre-tax income. The Company's effective tax rate was 23.9% and 26.8% for the years ended December 31, 2025 and 2024, respectively.

Net Interest Income

    For the year ended December 31, 2025, net interest income increased $43.7 million, or 24.5%, to $221.6 million from $178.0 million for the year ended December 31, 2024. For the year ended December 31, 2025, total interest income increased $19.5 million, or 4.3%, to $471.0 million, from $451.4 million for the year ended December 31, 2024. The increase in total interest income was primarily attributable to an increase in the average balance of loans coupled with an increase in average yields on loans and securities. The average yield on the loan portfolio for the year ended December 31, 2025 increased 8 basis points compared to the year ended December 31, 2024, while the average yield on the securities portfolio for the year ended December 31, 2025 increased 58 basis points as compared to the year ended December 31, 2024. This was primarily a result of lower yielding securities being sold as part of the balance sheet repositioning transaction implemented in the fourth quarter of 2024, and an increase in higher yielding securities purchased in 2025. The average yield on other interest-earning assets for the year ended December 31, 2025 decreased 109 basis points as compared to the year ended December 31, 2024, due to lower dividends received on Federal Home Loan Bank stock.

The average cost of our interest-bearing liabilities decreased 31 basis points to 3.13% for the year ended December 31, 2025, from 3.44% for the year ended December 31, 2024, primarily as a result of a decrease in the average cost of interest-bearing deposits and borrowings, and a decrease in the average balance of borrowings, partially offset by an increase in the average balance of deposits. For the year ended December 31, 2025, the average cost of interest-bearing deposits decreased 21 basis points. For the year ended December 31, 2025, total interest expense decreased $24.1 million, or 8.8%, to $249.3 million from $273.4 million for the year ended December 31, 2024. During 2025, the average cost of borrowings decreased 50 basis points, and there was a decrease in the average balance of borrowings.

Provision for Credit Losses

    A provision for credit losses of $9.8 million was recorded for the year ended December 31, 2025 as compared to $14.5 million for the year ended December 31, 2024. The decrease in provision for credit losses during the 2025 period was primarily attributable to a decrease in net charge-offs and a decrease in quantitative loss rates based upon the evaluation of current and projected economic conditions, partially offset by an increase in outstanding loan balances. Net charge-offs totaled $5.8 million for the year ended December 31, 2025, as compared to $9.6 million for the year ended December 31, 2024. Charge-offs are recorded on loans where management determines that the collection of loan principal and interest is unlikely. The provision for credit losses was determined by management to be an amount necessary to maintain a balance of allowance for credit losses at a level that uses relevant and reliable information from internal and external sources, related past events, current conditions, and a reasonable and supportable forecast. Changes in the provision were based on management’s analysis of various factors within the qualitative and quantitative components of the allowance for credit losses calculation. At December 31, 2025, the allowance for credit losses totaled $67.2 million, or 0.82% of total gross loans outstanding, compared to $60.0 million, or 0.76% of total gross loans outstanding, as of December 31, 2024. An analysis of the changes in the allowance for credit losses is presented under “Risk Management-Analysis and Determination of the Allowance for Credit Losses” below.

    For the year ended December 31, 2025, non-interest income increased $35.2 million to $37.1 million from $1.9 million for the year ended December 31, 2024. The increase was primarily attributable to an increase in the (loss) gain on securities transactions of $36.1 million which included a $34.6 million loss in the 2024 period resulting from the balance sheet repositioning transaction, an increase of $1.5 million in demand deposit account fees mainly related to commercial account treasury services, and an increase of $1.4 million in loan fees and service charges related to customer swap income, partially offset by a decrease in the change in fair value of equity securities of $1.7 million, and a decrease of $3.9 million in other non-interest income, mainly related to interest rate swaps. The $1.7 million decrease in the change in fair value of equity securities included the sale of a portion of Federal Home Loan Mortgage Corporation and Federal National Mortgage Association preferred stock included in equity securities.

Income Tax Expense

    Income tax expense of $16.2 million was recorded for the year ended December 31, 2025, reflecting an effective tax rate of 23.9%, compared to an income tax benefit of $4.3 million for 2024, reflecting an effective tax rate of 26.8%.

As of December 31, 2025, we had a net deferred tax liability totaling $15.3 million. We regularly evaluate the realizability of deferred tax asset positions. In determining whether a valuation allowance is necessary, we consider the level of taxable income in prior years to the extent that carrybacks are permitted under current tax laws, as well as estimates of future pre-tax and taxable income and tax planning strategies that would, if necessary, be implemented. As of December 31, 2025, it was concluded that no valuation allowance was required on the deferred tax assets related to Columbia Bank’s state net operating losses.

Results of Operations for the Year Ended December 31, 2024

    Financial Highlights

A net loss of $11.7 million was recorded for the year ended December 31, 2024, a decrease of $47.7 million, compared to net income of $36.1 million for the year ended December 31, 2023. The decrease was primarily attributable to a decrease in net interest income of $27.9 million, or 13.5%, an increase in provision for credit losses of $9.7 million, or 201.9%, and a decrease in non-interest income of $25.5 million, or 93.1%, partially offset by a decrease in non-interest expense of $1.1 million, or 0.6%, and a decrease in income tax expense of $14.2 million, or 142.7%. In 2024, the decrease in net interest income was primarily attributable to an $84.3 million increase in interest expense on deposits and borrowings, partially offset by a $56.4 million increase in interest income. The increase in interest income was primarily due to an increase in the average balance of total interest-earning assets coupled with an increase in average yields due to market interest rate increases in 2023. The increase in interest expense on deposits and borrowings was driven by these same rate increases coupled with intense competition for deposits in the market and the repricing of existing deposits into higher cost products along with higher balances. The increase in interest expense on borrowings was also impacted by the increase in interest rates for new borrowings along with an increase in the average balance of borrowings.

The provision for credit losses of $14.5 million recorded for the year ended December 31, 2024 as compared to $4.8 million recorded for the year ended December 31, 2023, was primarily due to net charge-offs totaling $9.6 million and an increase in loan performance qualitative factors.

The decrease in non-interest income of $25.5 million was primarily attributable to an increase in loss on securities transactions of $25.0 million, and a decrease in bank-owned life insurance income of $2.8 million, attributable to death benefits in 2023, partially offset by a $1.9 million increase in the fair value of Freddie Mac and Fannie Mae preferred stock included in equity securities.

The decrease of $1.1 million in non-interest expense was primarily attributable to a decrease in compensation and employee benefits expense of $11.4 million, partially offset by an increase in professional fees of $4.3 million, an increase in merger-related expenses of $1.1 million and an increase in loss on extinguishment of debt of $3.1 million, resulting primarily from the balance sheet repositioning transaction, and an increase in other non-interest expense of $2.0 million. The decrease in compensation and employee benefits expense was the result of lower incentive compensation and a workforce reduction related to cost cutting strategies implemented during 2023 and 2024. The increase in professional fees was primarily related to an increase in legal, regulatory and compliance related costs while the increase in other non-interest expense related to swap transactions.

Income tax benefit of $4.3 million was recorded for the year ended December 31, 2024, a decrease of $14.2 million, as compared to an expense of $10.0 million for the year ended December 31, 2023, mainly due to a decrease in pre-tax income. The Company's effective tax rate was 26.8% and 21.6% for the years ended December 31, 2024 and 2023, respectively.

    Net Interest Income

For the year ended December 31, 2024, net interest income decreased $27.9 million, or 13.5%, to $178.0 million from $205.9 million for the year ended December 31, 2023. For the year ended December 31, 2024, total interest income increased $56.4 million, or 14.3%, to $451.4 million, from $395.0 million for the year ended December 31, 2023. The increase in total interest income was primarily attributable to an increase in the average balances of total interest earning assets coupled with an increase in average yields. The yield on the loan portfolio for the year ended December 31, 2024 increased 46 basis points compared to the year ended December 31, 2023, while the yield on the securities portfolio for the year ended December 31, 2024 increased 40 basis points compared to the year ended December 31, 2023. The average yield on other interest-earning assets for the year ended December 31, 2024 increased 73 basis points compared to the year ended December 31, 2023. Increases in average yields on these portfolios for the year ended December 31, 2024 were influenced by market rates increasing 100 basis points throughout the 2023 period and remaining at elevated levels until reductions occurred during the last four months of 2024.

The average cost of our interest-bearing liabilities increased 92 basis points to 3.44% for the year ended December 31, 2024, from 2.52% for the year ended December 31, 2023, primarily as a result of an increase in the average cost of interest-bearing deposits and borrowings and increase in the average balances of interest-bearing deposits and borrowings. For the year ended December 31, 2024, the average cost of interest-bearing deposits increased 109 basis points. For the year ended December 31, 2024, total interest expense increased $84.3 million, or 44.6%, to $273.4 million from $189.1 million for the year ended December 31, 2023. During 2024, the average cost of borrowings increased 11 basis points, and there was an increase in the average balance of borrowings. The higher interest rate environment coupled with the higher cost of repricing deposits caused the overall increase in interest expense.

A provision for credit losses of $14.5 million was recorded for the year ended December 31, 2024 as compared to $4.8 million for the year ended December 31, 2023. The increase in provision for credit losses during the 2024 year was primarily attributable to net charge-offs recorded and an increase in loan performance qualitative factors. Net charge-offs totaled $9.6 million for the year ended December 31, 2024, as compared to $2.5 million for the year ended December 31, 2023. Charge-offs are recorded on loans where management determines that the collection of loan principal and interest is unlikely. The provision for credit losses was determined by management to be an amount necessary to maintain a balance of allowance for credit losses at a level that uses relevant and reliable information from internal and external sources, related past events, current conditions, and a reasonable and supportable forecast. Changes in the provision were based on management’s analysis of various factors within the qualitative and quantitative components of the allowance for credit losses calculation. At December 31, 2024, the allowance for credit losses totaled $60.0 million, or 0.76% of total gross loans outstanding, compared to $55.1 million, or 0.70% of total gross loans outstanding, as of December 31, 2023. An analysis of the changes in the allowance for credit losses is presented under “Risk Management-Analysis and Determination of the Allowance for Credit Losses” below.

For the year ended December 31, 2024, non-interest expense decreased $1.1 million, or 0.6%, to $181.3 million from $182.4 million for the year ended December 31, 2023. The decrease was primarily attributable to a decrease in compensation and employee benefits expense of $11.4 million, partially offset by an increase in professional fees of $4.3 million, an increase in merger-related expenses of $1.1 million and an increase in loss on extinguishment of debt of $3.1 million, resulting primarily from the balance sheet repositioning transaction, and an increase in other non-interest expense of $2.0 million. The decrease in compensation and employee benefits expense was the result of lower incentive compensation and a workforce reduction related to cost cutting strategies implemented during 2023 and 2024. The increase in professional fees was primarily related to an increase in legal, regulatory and compliance related costs, while the increase in other non-interest expense related to swap transactions. During the quarter ended December 31, 2024, the Company prepaid $170.0 million of FHLB borrowings as part of the previously discussed balance sheet repositioning transaction which resulted in a $3.3 million loss on the extinguishment of debt.

Income Tax Expense

58

Income tax benefit of $4.3 million was recorded for the year ended December 31, 2024, reflecting an effective tax rate of 26.8%, compared to income tax expense of $10.0 million for 2023, reflecting an effective tax rate of 21.6%.

As of December 31, 2024, we had a net deferred tax asset totaling $12.4 million. We regularly evaluate the realizability of deferred tax asset positions. In determining whether a valuation allowance is necessary, we consider the level of taxable income in prior years to the extent that carrybacks are permitted under current tax laws, as well as estimates of future pre-tax and taxable income and tax planning strategies that would, if necessary, be implemented. As of December 31, 2024, it was concluded that no valuation allowance was required on the deferred tax assets related to Columbia Bank’s state net operating losses.

Risk Management

Overview. Managing risk is an essential part of successfully managing a financial institution. Our most prominent risk exposures are credit risk, interest rate risk, liquidity risk, and market risk. Credit risk is the risk of not collecting the interest and/or the principal balance of a loan or investment when it is due. Interest rate risk is the potential reduction of interest income as a result of changes in interest rates. Liquidity risk is the possible inability to fund obligations to depositors, lenders or borrowers. Market risk arises from fluctuations in interest rates that may result in changes in the values of financial instruments, such as available for sale securities that are accounted for at fair value. Other risks that we face are operational risk and reputation risk. Operational risk includes risks related to fraud, regulatory compliance, processing errors, cyber attacks, and disaster recovery. Reputation risk is the risk that negative publicity or press, whether true or not, could cause a decline in our customer base or revenue.

We maintain a Risk Management Division comprised of our Risk Management, Compliance, Credit Risk Review, Collateral Risk, and Security Departments. Our Risk Management Division is led by our Senior Executive Vice President and Chief Risk Officer, who reports quarterly to Columbia Bank’s Risk Committee, which is comprised of the full board of directors. The current structure of our Risk Management Division is designed to monitor and address, among other things, financial, credit, collateral, consumer compliance, operational, Bank Secrecy Act, fraud, cyber security, vendor and insurable risks. The Risk Management Division utilizes a number of enterprise risk assessment tools, including stress testing, credit concentration reviews, peer analyses, industry considerations and individual risk assessments, to identify and report potential risks that we face in connection with our business operations.

Credit Risk Management. The objective of our credit risk management strategy is to quantify and manage credit risk and to limit the risk of loss resulting from an individual customer default. Our credit risk management strategy focuses on conservatism, diversification within the loan portfolio and monitoring. Our lending practices include conservative exposure limits and underwriting, documentation and collection standards. Our credit risk management strategy also emphasizes diversification on an industry and customer level as well as regular credit examinations and monthly management reviews of large credit exposures and loans experiencing deterioration in credit quality. Our credit risk review function provides objective assessments of the quality of underwriting and documentation, the accuracy of risk ratings and the charge-off, non-accrual and impact on the reserve analysis

62

process. Our credit review process and overall assessment of credit defaults and charge-offs on our allowance for credit losses is analyzed quarterly or as necessary. We use these assessments to identify potential problem loans within the portfolio, maintain an adequate reserve and take any necessary charge-offs when deemed appropriate.

When a borrower fails to make a required payment, we take a number of steps to have the borrower cure the delinquency and restore the loan to current status. Generally, our collection department follows the guidelines for servicing loans as prescribed by applicable law or the appropriate investor. Collection activities include, but are not limited to, phone calls to borrowers and collection letters, which include a late charge notice based on the contractual requirements of the specific loan. Additional calls and notices are mailed in compliance with state and federal regulations including, but not limited to, the Fair Debt Collection Practices Act. After the 90th day of delinquency for a residential mortgage or consumer loan, or on a different date as allowable by law or contract, the collection department will forward the account to counsel and begin the collection litigation which typically includes foreclosure proceedings, or we may periodically sell a delinquent loan to a third-party. If a foreclosure action is instituted and the loan is not in at least the early stages of a workout by the scheduled sale date, the real property securing the loan generally is sold at a sheriff sale. If we determine that there is a possibility of a settlement, pay-off or reinstatement, the sheriff sale may be postponed.

We charge off loans where management determines that the collection of loan principal and interest is unlikely. In addition to the individual review of larger commercial loans that exhibit probable or observed credit weaknesses, the commercial credit review process includes the use of an enhanced risk rating system. Historical portfolio performance metrics, current economic conditions and delinquency monitoring are factors used to assess the credit risk in our homogeneous commercial, residential and consumer loan portfolios.

Analysis of Non-Performing, Modification of Loans and Classified Assets. We consider repossessed assets and loans to be non-performing assets if the loans are 90 days or more in arrears of their contractual due date, or if the following criteria are met: i) the current debt-service coverage ratio is equal to or is in excess of 1.0x; ii) the guarantor does not demonstrate the capacity to support the annual debt service requirement; and iii) the loan-to-value percentage is greater than 90%. Non-accruing residential and consumer loans are returned to accrual status after there has been a sustained period of repayment performance and both principal and interest are deemed collectible.

Real estate that we acquire through foreclosure or by deed in lieu of foreclosure is classified as real estate owned until it is sold. When an asset is acquired, the excess of the loan balance over fair value less estimated costs to sell is charged to the allowance for credit losses. Operating results from real estate owned, including rental income, operating expenses, and gains and losses realized from the sales of real estate owned are recorded as incurred.

Loan modifications made to borrowers experiencing financial difficulty may include principal or interest forgiveness, forbearance, interest rate reductions, term extensions, or a combination of these events intended to minimize economic loss and to avoid foreclosure or repossession of collateral.

Modified loans that were accruing interest prior to their modification where income was reasonably assured subsequent to the modification, maintain their accrual status. Modified loans for which collectability was not reasonably assured, are placed on non-accrual status, interest accruals cease, and uncollected accrued interest is reversed and charged against current income. Non-accruing modified loans may be returned to accrual status when there is a sustained period of repayment performance (generally six consecutive months of payments), and both principal and interest are deemed collectible.

The following table sets forth information with respect to our non-performing assets at the dates indicated, excluding PCD loans. We did not have any accruing loans past due 90 days or more at any of the dates indicated.

(1) Includes $1.3 million, $3.1 million and $237,000 of loan modifications on non-accrual status as of December 31, 2025, 2024 and 2023, respectively.

Non-performing assets increased $15.0 million to $38.0 million, or 0.34% of total assets, at December 31, 2025 from $23.0 million, or 0.22% of total assets, at December 31, 2024. The $15.0 million increase in non-performing loans was primarily attributable to an increase in non-performing one-to-four family real estate loans of $1.0 million, an increase in non-performing commercial real estate loans of $2.8 million, an increase in non-performing commercial business loans of $5.4 million, and a $5.9 million construction loan designated as non-performing during the 2025 period. The $5.9 million non-performing construction loan was made to finance the construction of a mixed use five-story building with both commercial space and apartments. The increase in non-performing one-to-four family real estate loans was due to an increase in the number of loans from 32 non-performing loans at December 31, 2024 to 36 non-performing loans at December 31, 2025. The increase in non-performing commercial real estate loans was due to an increase in the number of loans from four non-performing loans at December 31, 2024 to nine non-performing loans at December 31, 2025. The increase in non-performing commercial business loans was primarily due to four non-performing loans totaling $8.1 million designated as non-accrual during the 2025 period, partially offset by one loan for $4.3 million which was paid off in 2025. The total number of non-performing commercial business loans increased from 11 non-performing loans at December 31, 2024 to 35 non-performing loans at December 31, 2025. Non-performing assets as a percentage of total assets totaled 0.34% at December 31, 2025, as compared to 0.22% at December 31, 2024.

Non-performing assets increased $10.4 million to $23.0 million, or 0.22% of total assets, at December 31, 2024 from $12.6 million, or 0.12% of total assets, at December 31, 2023. The $10.4 million increase in non-performing assets was primarily attributable to an increase in non-performing commercial business loans of $3.3 million and an increase in non-performing one-to-four family real estate loans of $5.6 million. The increase in non-performing commercial business loans primarily consists of two loans totaling $6.4 million at December 31, 2024, partially offset by the charge-off of a $3.7 million loan to a technology company during 2024. The increase in non-performing one-to-four family real estate loans was due to an increase in the number of loans from 17 non-performing loans at December 31, 2023 to 32 loans at December 31, 2024. Charge-offs are taken on loans where management determines that the collection of loan principal and interest is unlikely. We consider the population of loans in our impairment analysis to include all loan segments and not accruing interest, loans previously modified in a troubled debt restructuring if applicable, and other loans if there is specific information of a collateral shortfall. We continue to rigorously review our loan portfolio to ensure that the collateral values remain sufficient to support the outstanding balances.

Federal regulations require us to review and classify our assets on a regular basis. In addition, our banking regulators have the authority to identify problem assets and, if appropriate, require them to be classified. Our credit review process includes a risk classification of all commercial and residential loans that includes four levels of pass, special mention, substandard, doubtful and loss. A loan is classified as pass when payments are current and it is performing under the original contractual terms. A loan is classified as special mention when the borrower exhibits potential credit weakness or a downward trend which, if not checked or corrected, will weaken the asset or inadequately protect our position. While potentially weak, the borrower is currently marginally acceptable; no loss

64

of principal or interest is envisioned. A loan is classified as substandard when the borrower has a well-defined weakness or weaknesses that jeopardize the orderly liquidation of the debt. A substandard loan is inadequately protected by the current net worth and paying capacity of the obligor, normal repayment from this borrower is in jeopardy, and there is a distinct possibility that a partial loss of interest and/or principal will occur if the deficiencies are not corrected. A loan is classified as doubtful when a borrower has all weaknesses inherent in a substandard loan with the added provision that: (1) the weaknesses make collection of debt in full on the basis of currently existing facts, conditions and values highly questionable and improbable; (2) serious problems exist to the point where a partial loss of principal is likely; and (3) the possibility of loss is extremely high, but because of certain important, reasonably specific pending factors that may work to the advantage and strengthening of the assets, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors include proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens and additional refinancing plans. A loan is classified as loss when all or a portion of the loan is considered uncollectible and of such little value that its continuance on our books without establishment of a specific valuation allowance or charge off is not warranted. This classification does not necessarily mean that the loan has no recovery or salvage value. Rather, it indicates that there is significant doubt about how much or when recovery will occur.

A loan is considered delinquent when payment has not been received within 30 days of its contractual due date, or when the Company does not expect to receive all principal and interest payments owned substantially in accordance with the terms of the loan agreement, regardless of the past due status. Generally, a loan is designated as a non-accrual loan when the payment is 90 days or more in arrears of its contractual due date, or if the following criteria are met: i) the current debt-service coverage ratio is equal to or is

in excess of 1.0x; ii) the guarantor does not demonstrate the capacity to support the annual debt service requirement; and iii) the loan-to-value percentage is greater than 90%. Non-accruing loans are returned to accrual status after there has been a sustained period of repayment performance and both principal and interest are deemed collectible.

Analysis and Determination of the Allowance for Credit Losses

    The allowance for credit losses on loans is a valuation account that reflects management's evaluation of estimated losses in the current loan portfolio. We evaluate the need to establish allowances against losses on loans on a quarterly basis. When additional allowances are necessary, a provision for credit losses is charged to earnings. The ACL is maintained at a level management considers adequate to provide for estimated losses and impairment based upon an evaluation of known and inherent risk in the loan portfolio. The ACL consists of two elements: (1) identification of loans that must be individually analyzed for impairment and (2) establishment of an ACL for loans collectively analyzed.

    Individually Analyzed Loans. Management regularly monitors the condition of borrowers and assesses both internal and external factors in determining whether any relationships have deteriorated, considering factors such as historical loss experience, trends in delinquency and non-performing loans, changes in risk composition and underwriting standards, and regional and national economic conditions and trends.

Our loan officers and loan servicing staff identify and manage potential problem loans within our commercial loan portfolio. Non-performing assets within the commercial loan portfolio are transferred to the Special Assets Department for workout or litigation. The Special Assets Department reports directly to the Chief Financial Officer. Changes in management, financial or operating performance, company behavior, industry factors and external events and circumstances are evaluated on an ongoing basis to determine whether potential impairment is evident and additional analysis is needed. For our commercial loan portfolio, risk ratings are assigned to each individual loan to differentiate risk within the portfolio and are reviewed on an ongoing basis by credit management and the Credit Risk Review Department and revised, if needed, to reflect the borrower’s current risk profiles and the related collateral positions.

The risk ratings consider factors such as financial condition, debt capacity and coverage ratios, market presence and quality of management. When a credit’s risk rating is downgraded to a certain level, the relationship must be reviewed and detailed reports completed that document risk management strategies for the credit going forward, and the appropriate accounting actions to take in accordance with generally accepted accounting principles in the United States. When credits are downgraded beyond a certain level, our Special Assets and Loan Servicing Departments become responsible for managing the credit risk.

The Asset Classification Committee reviews risk rating actions (specifically downgrades or upgrades between pass and the criticized and classified categories) recommended by Lending, Loan Servicing, Commercial Credit, Credit Risk Review and/or Special Assets Departments on a quarterly basis. Our Commercial Credit, Credit Risk Review, Lending, and Loan Servicing Departments monitor our commercial, residential and consumer loan portfolios for credit risk and deterioration considering factors such as delinquency, loan to value ratios and credit scores.

When problem loans are identified that are secured with collateral, management examines the loan files to evaluate the nature and type of collateral supporting the loans. Management documents the collateral type, date of the most recent valuation, and whether any liens exist, to determine the value to compare against the committed loan amount. If a loan is identified as impaired and is collateral dependent, an updated appraisal is obtained to provide a baseline in determining the property’s fair value. A collateral dependent impaired loan is written down to its appraised value and a specific allowance is established to cover potential selling costs. If the collateral value is subject to significant volatility (due to location of asset, obsolescence, etc.) an appraisal is obtained more frequently. In-house revaluations are typically performed on a quarterly basis and updated appraisals are obtained annually, if determined necessary.

When we determine that the value of an impaired loan is less than its carrying amount, we recognize impairment through a charge-off to the allowance for credit losses. We perform these assessments on an ongoing basis. Charge-offs against the ACL are taken on loans where management determines that the full collection of loan principal and interest is unlikely.

    Collectively Analyzed Loans. Additionally, we reserve for certain inherent, but undetected, losses that are probable within the loan portfolio. This is due to several factors, such as, but not limited to, inherent delays in obtaining information regarding a customer’s financial condition or changes in their unique business conditions and the interpretation of economic trends. While this analysis is conducted at least quarterly, we have the ability to revise the allowance factors whenever necessary to address improving or deteriorating credit quality trends or specific risks associated with a given loan pool classification.

A comprehensive analysis of the allowance for credit losses on loans is performed on a quarterly basis. The entire allowance for credit losses on loans is available to absorb losses in the loan portfolio irrespective of the amount of each separate element of the ACL. Our principal focus, therefore, is on the adequacy of the total allowance for credit losses.

Although we believe we have established and maintained the ACL on loans at appropriate levels, changes in reserves may be necessary if actual economic and other conditions differ substantially from the forecast used in estimating the ACL. See note 2 to our consolidated financial statements for a detailed discussion of our accounting policies and methodologies for establishing the ACL.

66

The allowance for credit losses is subject to review by our banking regulators. On a periodic basis our primary bank regulator conducts an examination of the allowance for credit losses and makes an assessment regarding its adequacy and the methodology employed in its determination.

    Total Loans. During the year ended December 31, 2025, the balance of the allowance for credit losses increased by $7.2 million to $67.2 million, or 0.82% of total gross loans at December 31, 2025, from $60.0 million, or 0.76%, of total gross loans at December 31, 2024. The increase in the total loan coverage ratio for the year ended December 31, 2025 was primarily attributable to an increase in outstanding loan balances.

    One-to-Four Family Loan Portfolio. The portion of the allowance for credit losses related to the one-to-four family real estate loan portfolio totaled $13.3 million, or 0.5%, of one-to-four family loans at December 31, 2025, as compared to $13.2 million, or 0.5%, of one-to-four family real estate loans at December 31, 2024. Our one-to-four family non-accrual loans increased $1.0 million, or 11.9%, to $9.8 million at December 31, 2025 from $8.8 million at December 31, 2024. Net recoveries were $73,000 for the year ended December 31, 2025 compared to net charge-offs of $9,000 for the year ended December 31, 2024. We believe the one-to-four family real estate loan reserve ratio was appropriate given the continued low balance of charge-offs.

Multifamily Loan Portfolio. The portion of the allowance for credit losses related to the multifamily real estate loan portfolio totaled $10.6 million, or 0.6%, of multifamily loans at December 31, 2025, as compared to $9.5 million, or 0.7%, of multifamily loans at December 31, 2024. There were no multifamily non-accrual loans at December 31, 2025 and 2024. There were no charge-offs or recoveries for the years ended December 31, 2025 and 2024. We believe the multifamily loan reserve ratio was appropriate as there were no non-accrual loans or charge-offs.

Commercial Real Estate Loan Portfolio. The portion of the allowance for credit losses related to the commercial real estate loan portfolio totaled $18.6 million, or 0.7%, of commercial real estate loans at December 31, 2025, as compared to $16.0 million, or 0.7%, of commercial real estate loans at December 31, 2024. Commercial real estate non-accrual loans increased to $5.8 million at December 31, 2025, from $2.9 million at December 31, 2024. Net charge-offs were $118,000 for the year ended December 31, 2025 and $84,000 for the year ended December 31, 2024. We believe the commercial real estate loan reserve ratio was appropriate given the continued low balance of non-accrual loans comparative to the segment total for loans along with low level of charge-offs.

Construction Loan Portfolio.  The portion of the allowance for credit losses related to the construction loan portfolio totaled $6.6 million, or 1.4%, of construction loans at December 31, 2025, as compared to $6.7 million, or 1.4%, of construction loans at December 31, 2024. We had one non-accrual construction loan with a balance of $5.9 million at December 31, 2025. There were no non-accrual construction loans at December 31, 2024. Net charge-offs were $50,000 for the year ended December 31, 2025 and there

67

were no charge-offs for the year ended December 31, 2024. We believe the construction loan reserve ratio was appropriate as there were no non-accrual loans and considering the inherent credit risk associated with this portfolio.

Commercial Business Loan Portfolio. The portion of the allowance for credit losses related to the commercial business loan portfolio totaled $16.8 million, or 2.2%, of commercial business loans at December 31, 2025, as compared to $13.1 million, or 2.1%, of commercial business loans at December 31, 2024. Commercial business non-accrual loans increased to $15.3 million at December 31, 2025, from $9.8 million at December 31, 2024. Net charge-offs were $5.6 million for the year ended December 31, 2025 compared to $9.3 million for the year ended December 31, 2024. We continue to take charge-offs where management determines that the collection of loan principal and interest is unlikely or for any collateral deficiency for non-performing loans. We believe the commercial business loan reserve ratio was appropriate given the inherent credit risk of commercial business loans.

Home Equity Loans and Advances. The portion of the allowance for credit losses related to the home equity loan portfolio totaled $1.3 million, or 0.5%, of home equity loans at December 31, 2025, as compared to $1.5 million, or 0.6%, of home equity loans at December 31, 2024. Home equity non-accrual loans increased to $1.2 million at December 31, 2025, from $246,000 at December 31, 2024. There were no charge-offs and recoveries were $90,000 for the year ending December 31, 2025, as compared to recoveries of $19,000 for the year ending December 31, 2024. We believe the home equity loan reserve was appropriate based upon the insignificant amount of delinquencies, non-accrual loans and charge-offs.

Interest Rate Risk Management

Interest rate risk is defined as the exposure of a Company's current and future earnings and capital arising from movements in market interest rates. Depending on a bank’s asset/liability structure, adverse movements in interest rates could be either rising or falling interest rates. For example, a bank with predominantly long-term fixed-rate assets and short-term liabilities could have an adverse earnings exposure to a rising rate environment. Conversely, a short-term or variable-rate asset base funded by longer-term liabilities could be negatively affected by falling rates. This is referred to as re-pricing or maturity mismatch risk.

Interest rate risk also arises from changes in the slope of the yield curve (yield curve risk), from imperfect correlations in the adjustment of rates earned and paid on different instruments with otherwise similar re-pricing characteristics (basis risk), and from interest rate related options embedded in our assets and liabilities (option risk).

Our objective is to manage our interest rate risk by determining whether a given movement in interest rates affects our net interest income and the market value of our portfolio equity in a positive or negative way and to execute strategies to maintain interest rate risk within established limits. The results at December 31, 2025 indicate a level of risk within the parameters of our model. Our management believes that the December 31, 2025 results indicate a profile that reflects an acceptable level of interest rate risk exposures in both rising and declining rate environments for both net interest income and economic value.

Model Simulation Analysis. We view interest rate risk from two different perspectives. The traditional accounting perspective, which defines and measures interest rate risk as the change in net interest income and earnings caused by a change in interest rates, provides the best view of short-term interest rate risk exposure. We also view interest rate risk from an economic perspective, which defines and measures interest rate risk as the change in the market value of portfolio equity caused by changes in the values of assets and liabilities, which fluctuate due to changes in interest rates. The market value of portfolio equity, also referred to as the economic value of equity, is defined as the present value of future cash flows from existing assets, minus the present value of future cash flows from existing liabilities.

These two perspectives give rise to income simulation and economic value simulation, each of which presents a unique picture of our risk of any movement in interest rates. Income simulation identifies the timing and magnitude of changes in income resulting from changes in prevailing interest rates over a short-term time horizon (usually one or two years). Economic value simulation reflects the interest rate sensitivity of assets and liabilities in a more comprehensive fashion, reflecting all future time periods. It can identify the quantity of interest rate risk as a function of the changes in the economic values of assets and liabilities, and the corresponding change in the economic value of equity of Columbia Bank. Both types of simulation assist in identifying, measuring, monitoring and managing interest rate risk and are employed by management to ensure that variations in interest rate risk exposure will be maintained within policy guidelines.

We produce these simulation reports and review them regularly with our management, Asset/Liability Committee and Board Risk Committee. The simulation reports compare baseline (no interest rate change) to the results of an interest rate shock, to illustrate the specific impact of the interest rate scenario tested on income and equity. The model, which incorporates all asset and liability rate information, simulates the effect of various interest rate movements on income and equity value. The reports identify and measure our interest rate risk exposure present in our current asset/liability structure. Management considers both a static (current position) and dynamic (forecast changes in volume) analysis as well as non-parallel and gradual changes in interest rates and the yield curve in assessing interest rate exposures.

70

If the results produce quantifiable interest rate risk exposure beyond our limits, then the testing will have served as a monitoring mechanism to allow us to initiate asset/liability strategies designed to reduce and therefore mitigate interest rate risk.

Certain shortcomings are inherent in the methodologies used in the interest rate risk measurements. Modeling changes in net interest income requires the use of certain assumptions regarding prepayment and deposit repricing, which may or may not reflect the manner in which actual yields and costs respond to changes in market interest rates. While management believes such assumptions are reasonable, there can be no assurance that assumed prepayment rates and repricing rates will approximate actual future asset prepayment and liability repricing activity.

The table below sets forth an approximation of our interest rate exposure. Net interest income assumes that the composition of interest sensitive assets and liabilities existing at the beginning of a period remains constant over the period being measured and also assumes that a particular change in interest rates is reflected uniformly across the yield curve regardless of the duration to maturity or repricing of specific assets and liabilities. Accordingly, although the net interest income table provides an indication of our interest rate risk exposure at a particular point in time, such measurement is not intended to and does not provide a precise forecast of the effect of changes in market interest rates on our net interest income and will differ from actual.

    The table below sets forth, as of December 31, 2025, the net portfolio value, the estimated changes in the net portfolio value, and the net interest income that would result from the designated instantaneous parallel changes in market interest rates. This data is for Columbia Bank and its subsidiaries only and does not include any assets of the Company.

    As of December 31, 2025, based on the scenarios above, net interest income would decrease by approximately 9.06% if rates were to rise 200 basis points, and would increase by 8.70% if rates were to decrease 200 basis points over a one-year time horizon.

Another measure of interest rate sensitivity is to model changes in the net portfolio value through the use of immediate and sustained interest rate shocks. As of December 31, 2025, based on the scenarios above, in the event of an immediate and sustained 200 basis point increase in interest rates, the NPV is projected to decrease 13.85%. If rates were to decrease 200 basis points, the model forecasts a 9.37% increase in the NPV.

Overall, our December 31, 2025 results indicate that we are adequately positioned with an acceptable net interest income and economic value at risk in all scenarios and that all interest rate risk results continue to be within our policy guidelines.

Liquidity Management

Liquidity risk is the risk of being unable to meet future financial obligations as they come due at a reasonable funding cost. We mitigate this risk by attempting to structure our balance sheet prudently and by maintaining diverse borrowing resources to fund potential cash needs. For example, we structure our balance sheet so that we fund less liquid assets, such as loans, with stable funding sources, such as retail deposits, long-term debt, wholesale borrowings, and capital. We assess liquidity needs arising from asset growth, maturing obligations, and deposit withdrawals, taking into account operations in both the normal course of business and times of unusual events. In addition, we consider our off-balance sheet arrangements and commitments that may impact liquidity in certain business environments.

Our Asset/Liability Committee measures liquidity risks, sets policies to manage these risks, and reviews adherence to those policies at its quarterly meetings. For example, we manage the use of short-term unsecured borrowings as well as total wholesale

71

funding through policies established and reviewed by our Asset/Liability Committee. In addition, the Risk Committee of our board of directors reviews liquidity limits and reviews current and forecasted liquidity positions at each of its regularly scheduled meetings.

We have contingency funding plans that assess liquidity needs that may arise from certain stress events such as rapid asset growth or financial market disruptions. Our contingency plans also provide for continuous monitoring of net borrowed funds and dependence and available sources of contingent liquidity. These sources of contingent liquidity include cash and cash equivalents, capacity to borrow at the Federal Reserve discount window and through the FHLB system, fed funds purchased from other banks and the ability to sell, pledge or borrow against unencumbered securities in our securities portfolio. As of December 31, 2025, the potential liquidity from these sources is an amount we believe currently exceeds any contingent liquidity need.

Uses of Funds. Our primary uses of funds include the extension of loans and credit, the purchase of securities, working capital, and debt and capital management. In addition, contingent uses of funds may arise from events such as financial market disruptions.

We regularly adjust our investments in liquid assets based upon our assessment of: (1) expected loan demand, (2) expected deposit flows, (3) yields available on interest-earning deposits and securities, (4) repayment of borrowings, and (5) the objectives of our asset/liability management program. Excess liquid assets are generally invested in fed funds.

Sources of Funds. Our most liquid assets are cash and cash equivalents. The levels of these assets are dependent on our operating, investing and financing activities during any given period. At December 31, 2025, total cash and cash equivalents totaled $340.8 million. Debt securities classified as available for sale, and equity securities, which provide additional sources of liquidity, totaled $1.1 billion, and $6.8 million, respectively, at December 31, 2025. At December 31, 2025, we had $1.2 billion in Federal Home Loan Bank fixed rate advances. In addition, if Columbia Bank requires funds beyond its ability to generate them internally, it can borrow additional funds under the FHLB's overnight advance program up to its maximum borrowing capacity based on their ability to collateralize such borrowings.

Our primary sources of funds include a large, stable deposit base. Core deposits (consisting of demand, money market and savings and club deposits), primarily generated from our retail branch network, are our largest and most cost-effective source of funding. Core deposits totaled $5.6 billion and $5.4 billion at December 31, 2025 and 2024, respectively. We also maintain access to a diversified base of wholesale funding sources. These uncommitted sources include federal funds purchased from other banks, securities sold under agreements to repurchase, and FHLB advances. Aggregate wholesale funding totaled $1.2 billion at December 31, 2025, compared to $1.1 billion as of December 31, 2024. In addition, at December 31, 2025, we had the availability to borrow additional funds, subject to our ability to collateralize such borrowings from the FHLBNY and the Federal Reserve Bank.

A significant use of our liquidity is the funding of loan originations. At December 31, 2025, the Company had $264.2 million in loan commitments outstanding, which primarily consisted of commitments to fund loans of $18.1 million, $68.2 million, $41.1 million, $101.1 million, and $4.2 million, in one-to-four family real estate, commercial real estate, commercial business, construction, and home equity loans and advances, respectively. There was also $1.1 billion in unused commercial business, construction and consumer lines of credit, and $22.9 million in letters of credit. Since these commitments may expire without being drawn upon, and may have conditions, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management's credit evaluation of the borrower. Another significant use of liquidity is the funding of deposit withdrawals. Certificates of deposit due within one year of December 31, 2025 totaled $2.5 billion, or 86.5% of total certificates of deposit. The large percentage of certificates of deposit that mature within one year reflects customers’ hesitancy to invest their funds for long periods. Management believes, however, based on past experience, that a significant portion of our certificates of deposit will be renewed. If these maturing deposits do not remain with us, we will be required to seek other sources of funds, including other certificates of deposit and borrowings. Depending on market conditions, we may be required to pay higher rates on such deposits and borrowings than we currently pay on the certificates of deposit due on or before December 31, 2025. We have the ability to attract and retain deposits by adjusting the interest rates offered.

    Our primary investing activities are the origination of loans and the purchase of securities. Our primary financing activities consist of activity in deposit accounts, borrowings and treasury stock. Deposit flows are affected by the overall level of market interest rates, the interest rates and products offered by us, local competitors and other factors. We generally manage the pricing of our deposits to be competitive. Occasionally, we offer promotional rates on certain deposit products to attract deposits.

Columbia Financial is a separate legal entity from Columbia Bank and must provide for its own liquidity in addition to its operating expenses. Columbia Financial's primary source of income is dividends received from Columbia Bank. The amount of dividends Columbia Bank may declare and pay to Columbia Financial is generally restricted under federal regulations to the retained earnings of Columbia Bank. At December 31, 2025, on a stand-alone basis, Columbia Financial had liquid assets of $31.6 million.

Capital Management. We are subject to various regulatory capital requirements administered by our federal banking regulators, including a risk-based capital measure. The Federal Reserve establishes capital requirements, including well capitalized standards, for our consolidated financial holding company, and the OCC has similar requirements for our Company's subsidiary banks. The risk-based capital guidelines include both a definition of capital and a framework for calculating risk-weighted assets by assigning balance sheet assets and off-balance sheet items to broad risk categories. At December 31, 2025, we exceeded all of our regulatory

72

capital requirements. We are considered “well capitalized” under regulatory guidelines. See “Item 1: Business - Regulation and Supervision - Federal Banking Regulations - Capital Requirements” and note 13 in the notes to the consolidated financial statements included in this report.

Off-Balance Sheet Arrangements.  In the normal course of operations, we engage in a variety of financial transactions that, in accordance with generally accepted accounting principles, are not recorded in the consolidated financial statements. These transactions involve, to varying degrees, elements of credit, interest rate and liquidity risk. Such transactions are used primarily to manage customers’ requests for funding and take the form of loan commitments and lines of credit. For information about our loan commitments, see note 16 in the notes to the consolidated financial statements included in this report.

For the years ended December 31, 2025 and 2024, we did not engage in any off-balance sheet transactions reasonably likely to have a material effect on our financial condition, results of operations or cash flows.

    Derivative Financial Instruments. Columbia Bank executes interest rate swaps with third parties in order to hedge the interest expense of FHLBNY advances. Those interest rate swaps are simultaneous with entering into short-term borrowings with the FHLBNY. These derivatives are designated as cash flow hedges and are not speculative. As these interest rate swaps meet the hedge accounting requirements, the effective portion of changes in the fair value are recognized in accumulated other comprehensive income. As of December 31, 2025, Columbia Bank had 33 interest rate swaps with notional amounts of $393.7 million hedging certain FHLBNY advances.

Columbia Bank presently offers interest rate swaps to commercial banking customers to manage their risk of exposure and risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that Columbia Bank executes with a third-party, such that Columbia Bank would minimize its net risk exposure resulting from such transactions. These derivatives are not designated as hedges and are not speculative. Rather, these derivatives result from a service Columbia Bank offers to certain customers. As the interest rate swaps would not meet the hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting third-party swap contracts are recognized directly in earnings. At December 31, 2025, we had interest rate swaps in place with 92 commercial banking customers executed by offsetting interest rate swaps with third parties, with aggregated notional amounts of $387.2 million.

Columbia Bank offers currency forward contracts to certain commercial banking customers to facilitate international trade. Those forward contracts are simultaneously hedged by offsetting forward contracts that Columbia Bank would execute with a third- party, such that Columbia Bank would minimize its net risk exposure resulting from such transactions. These derivatives are not designated as hedges and are not speculative. Rather, these derivatives result from a service Columbia Bank offers to certain commercial customers. As the currency forward contract does not meet the hedge accounting requirements, changes in the fair value of both the customer forward contract and the offsetting forward contract is recognized directly in earnings. At December 31, 2025, Columbia Bank had no currency forward contracts in place with commercial banking customers.

The Company also uses interest rate swaps to manage its exposure to changes in fair value of certain of its fixed-rate pools of assets attributable to changes in the designated benchmark interest rate, of SOFR. At December 31, 2025, the Company had no interest rate fair value swaps.

Recent Accounting Pronouncements

For a discussion of the impact of recent accounting pronouncements, see note 2 in the notes to the consolidated financial statements included in this report.

Effect of Inflation and Changing Prices

The consolidated financial statements and related consolidated financial data presented in this report have been prepared in accordance with accounting principles generally accepted in the United States of America, which require the measurement of financial position and operating results in terms of historical dollars without considering changes in the relative purchasing power of money over time due to inflation. The primary impact of inflation on our operations is reflected in increased operating costs. Unlike most industrial companies, virtually all the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates generally have a more significant impact on a financial institution’s performance than do general levels of inflation. Interest rates do not necessarily move in the same direction or to the same extent as the prices of goods and services because such prices are affected by inflation to a larger extent than interest rates.
