**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**Note 1 – Summary of Significant Accounting Policies** 

The accounting and financial reporting policies of Columbia Banking System, Inc. conform to accounting principles generally accepted in the United States of America and with prevailing practices within the banking and securities industries. All references in this report to "Columbia," "we," "our," or "us" or similar references mean the Company and its subsidiaries, including the wholly-owned banking subsidiary Columbia Bank (the "Bank"). FinPac is a commercial equipment leasing company and a wholly-owned subsidiary of the Bank. The accompanying interim consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, and the Bank's wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated. The consolidated financial statements have not been audited. A more detailed description of the Company's accounting and financial reporting policies is included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

***Basis of Presentation*** - In preparing these consolidated financial statements, the Company has evaluated events and transactions subsequent to March 31, 2026, for potential recognition or disclosure. In management's opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying financial statements have been made. These adjustments include those that are normal and recurring in nature and considered necessary for a fair presentation. The results for interim periods are not necessarily indicative of results for the full year or any other interim period.

In 2025, management elected to change the presentation of the Company's financial statements and accompanying footnote disclosures from thousands to millions. The change in presentation had no material impact on previously reported financial information, but certain amounts reported for prior periods may differ by insignificant amounts due to the nature of rounding relative to the change in presentation. In addition, historical percentages and per share amounts presented may not add to their respective totals or recalculate due to rounding.

**Note 2 – Business Combinations**

***Acquisition of Pacific Premier***

On August 31, 2025, Columbia completed its acquisition of Pacific Premier, which was wholly acquired in an all-stock transaction valued at $2.4 billion. On September 1, 2025, Pacific Premier's wholly owned banking subsidiary, Pacific Premier Bank, National Association, merged with and into Columbia Bank. Pursuant to the acquisition agreement, each share of Pacific Premier common stock was exchanged for 0.9150 of a share of Columbia common stock.

The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. Fair value measurements were based on significant estimates and assumptions in effect as of the acquisition date and may be subject to adjustment during the measurement period. As of March 31, 2026, the initial accounting for deferred taxes remains preliminary, as the tax returns have not yet been finalized. Accordingly, the deferred tax amounts recognized in the consolidated financial statements are provisional and subject to adjustment during the measurement period, which will not exceed one year from the acquisition date, with any such adjustment recorded to goodwill. Additional information regarding valuation methodologies, as well as the fair values and unpaid principal loan balances acquired, is included in Note 2 – *Business Combinations* of the Notes to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

The Company's consolidated results for the three months ended March 31, 2026 include the operating results of Pacific Premier's operations subsequent to the August 31, 2025 acquisition date. Separate operating results for Pacific Premier are not presented, as they are not practicable to determine following the integration of operations.

During the three months ended March 31, 2026, the Company incurred $20 million of acquisition-related expenses associated with the acquisition of Pacific Premier. These costs were expensed as incurred and primarily included in non-interest expense.

The following unaudited pro forma financial information presents the Company's results as if the acquisition of Pacific Premier had occurred on January 1, 2024. This information is provided for illustrative purposes only and is not necessarily indicative of actual results. Pro forma adjustments primarily reflect estimated interest income and expense adjustments and amortization of core deposit intangibles and do not reflect anticipated operating cost savings, synergies, or other integration benefits.

The number of individual debt securities in an unrealized loss position in the tables above increased to 811 as of March 31, 2026, as compared to 592 at December 31, 2025. The unrealized losses in the Company's debt securities portfolio are primarily attributable to changes in market interest rates or the widening of market spreads subsequent to the initial purchase of these securities, rather than deterioration in the credit quality of the issuers. Management actively monitors the published credit ratings of the issuers of the debt securities for any material changes in rating or outlooks. As the decline in fair value of the debt securities is attributable to interest rate movements and market spread volatility and not credit related factors, no ACL has been recorded on these debt securities as of March 31, 2026.

The following table presents the contractual maturities of the Company's debt securities as of March 31, 2026. Actual maturities may differ from contractual maturities due to the potential for early calls, prepayments, or principal repayments, with or without call or prepayment penalties.

The Company elected to exclude accrued interest receivable from the amortized cost basis of loans and leases disclosed throughout this note. Interest accrued on loans and leases totaled $188 million and $186 million as of March 31, 2026 and December 31, 2025, respectively, and is included in other assets on the Consolidated Balance Sheets. As of March 31, 2026, loans totaling $30.3 billion were pledged to secure borrowings and available lines of credit, compared to $30.6 billion as of December 31, 2025.

As of March 31, 2026 and December 31, 2025, the net deferred fees and costs were $57 million and $54 million, respectively. Originated loans and leases are reported at the principal amount outstanding, net of deferred fees and costs, any partial charge-offs recorded, and interest applied to principal. Total loans and leases also include discounts on acquired loans of $666 million and $707 million as of March 31, 2026 and December 31, 2025, respectively.

Purchased loans are recorded at fair value at the date of purchase. The Company evaluates purchased loans for more-than-insignificant deterioration at the date of purchase. Purchased loans that have experienced more-than-insignificant deterioration from origination are considered PCD loans. All other purchased loans are considered non-PCD loans. The outstanding contractual unpaid principal balance of PCD loans, excluding acquisition accounting adjustments, was $467 million and $473 million as of March 31, 2026 and December 31, 2025, respectively. The carrying balance of PCD loans was $411 million and $416 million as of March 31, 2026 and December 31, 2025, respectively.

The Bank, through its commercial equipment leasing subsidiary, FinPac, is a provider of commercial equipment leasing and financing. Direct finance leases are included within the leases and equipment finance segment within the loans and leases, net line item. These direct financing leases typically have terms of three years to five years. Interest income recognized on these leases was $6 million for both the three months ended March 31, 2026 and March 31, 2025.

**Note 5 – Allowance for Credit Losses** 

The ACL represents management's estimate of expected lifetime credit losses for financial assets measured at amortized costs, including loans and leases and unfunded commitments. For a description of the Company's ACL methodology and significant assumptions, refer to Note 1 – *Summary of Significant Accounting Policies* included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

At March 31, 2026, the ACL was $478 million, a decrease of $7 million from the December 31, 2025 balance of $485 million. The change in the ACL primarily reflects credit migration trends and changes in the economic assumptions incorporated into the Company's credit loss models. The Company estimates expected credit losses using internally developed models that project PD and LGD for loans and leases, incorporating forecasted economic conditions and relevant macroeconomic variables. Management evaluates multiple economic scenarios at each measurement date and selects the scenario determined to be most probable based on current economic conditions. Forecast assumptions are updated periodically and incorporated into the ACL calculation. Changes in projected macroeconomic variables over the forecast period may materially impact the ACL, with uncertainty increasing over longer projection horizons.

The Bank opted to use Moody's Analytics' February 2026 consensus economic forecast for estimating the ACL as of March 31, 2026. The forecast used to calculate the ACL as of March 31, 2026 is projecting higher GDP growth, higher unemployment rates, and average federal funds rates trending lower. This is compared to the December 31, 2025 ACL calculation, which used Moody's Analytics' November 2025 consensus economic forecast to forecast the variables used in the models.

In the consensus scenario, the probability that the economy will perform better than this consensus is equal to the probability that it will perform worse and includes the following variables:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **2026** | **2027** | **2028** | **2029** |
| U.S. real GDP average annualized growth | 2.8% | 2.0% | 2.0% | 2.0% |
| U.S. unemployment rate average | 4.5% | 4.3% | 4.2% | 4.1% |
| Forecasted average federal funds rate | 3.4% | 3.2% | 3.3% | 3.2% |

---

The Bank uses an additional scenario with the same economic variables, but with varying severity, to assess ACL sensitivity and inform qualitative adjustments. For this analysis, the Bank selected Moody's Analytics' February 2026 S2 scenario (the "S2 Scenario"), which predicts a 75% probability of better economic performance and a 25% probability of worse performance. The S2 Scenario includes the following variables:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **2026** | **2027** | **2028** | **2029** |
| U.S. real GDP average annualized growth | 1.6% | 0.5% | 2.4% | 2.5% |
| U.S. unemployment rate average | 5.9% | 6.6% | 4.6% | 4.5% |
| Forecasted average federal funds rate | 3.1% | 2.2% | 2.2% | 3.1% |

---

Management reviewed the results derived from the economic scenarios and subsequent changes in macroeconomic variables for sensitivity analysis, considering these factors when evaluating qualitative adjustments. Along with the quantitative factors produced by the above models, management also considers prepayment speeds and qualitative factors when determining the ACL. As of March 31, 2026, the Company evaluated qualitative factors and applied a net upward adjustment to the quantitative results for the ACL, which is directionally consistent with the adjustments made as of December 31, 2025. These overlays primarily focus on the change in economic environment that occurred between the selection of the Moody's Analytics February 2026 consensus forecast and March 31, 2026. This approach utilizes the Moody's Analytics S2 scenario forecast to account for the impact of additional negative factors that occurred between the selected forecast and the as of date of the financial statements. This is intended to provide an allowance estimate incorporating the most current economic environment data available to management. This approach helps ensure that the allowance remains appropriately resilient and responsive to emerging risks, thereby supporting the resilience of the Bank's credit portfolio. By incorporating these targeted overlays, we aim to enhance the accuracy and robustness of our risk management strategy, providing a more comprehensive and adaptive approach to potential economic shifts.

Management believes that the ACL was adequate as of March 31, 2026. There is, however, no assurance that future loan losses will not exceed the levels provided for in the ACL and could possibly result in additional charges to the provision for credit losses.

***Asset Quality and Non-Performing Loans and Leases***

The Bank actively manages asset quality and controls credit risk through diversification of the loan and lease portfolio and the application of policies designed to promote sound underwriting and loan and lease monitoring practices. The Bank's Credit Quality Administration department is charged with monitoring asset quality, establishing credit policies and procedures, and enforcing the consistent application of these policies and procedures across the Bank. The Bank conducts ongoing reviews of non-performing, past due loans and leases and larger credits, designed to identify potential charges to the ACL, and to determine the adequacy of the ACL. These reviews incorporate a variety of factors, including the financial strength of borrowers, collateral valuations, loan and lease loss experience, estimated loan and lease losses, growth in the loan and lease portfolio, prevailing economic conditions, and other relevant factors.

***Loans and Leases Past Due and Non-Accrual Loans and Leases***

Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on non-accrual status when, in management's opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. As of March 31, 2026 and December 31, 2025, loans and leases on non-accrual status with no related ACL were $1 million and $2 million, respectively, excluding collateral-dependent loans and leases that have been written down to net realizable value without an associated ACL of $110 million and $67 million, respectively. The remaining balance of non-accrual loans are substantially covered by government guarantees. The Company recognized no interest income on non-accrual loans and leases during the three months ended March 31, 2026 and 2025.

The following tables present the carrying value of the loans and leases past due, by loan and lease class, as of the dates presented:

***Loan and Lease Modifications Made to Borrowers Experiencing Financial Difficulty***

The ACL on modified loans or leases is measured using the same credit loss estimation methods used to determine the ACL for all other loans and leases held for investment. These methods incorporate the post-modification loan or lease terms, as well as defaults and charge-offs associated with the modified loans and leases.

The following tables present the amortized cost basis of loans and leases that were both experiencing financial difficulty and modified during the three months ended March 31, 2026 and 2025, by class and type of modification. The percentage of the amortized cost basis of loans and leases to borrowers in financial distress that were modified as compared to the amortized cost basis of each class of financing receivable is also presented below.

***Credit Quality Indicators***

Management regularly reviews loans and leases in the portfolio to assess credit quality indicators and to determine appropriate loan classification and grading. The Bank separates its loans and lease portfolios into homogeneous and non-homogeneous categories. Homogeneous loans are rated based on past due status and may enter a higher risk rating scale if modified, requiring six months of timely payments to return to the lower risk rating scale. Non-homogeneous loans use a dual risk rating approach: the PD scale measures the likelihood of default, and the LGD scale measures potential loss if a default occurs. The product of PD and LGD gives the expected loss, providing a common language of credit risk across different loans. For more information about the Company's credit quality indicators, refer to Note 6 – *Allowance for Credit Losses* included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

**Note 6 – Goodwill and Other Intangible Assets**

The Company had $1.5 billion in goodwill as of March 31, 2026 and December 31, 2025, which represents the excess of the total acquisition price paid over the fair value of the assets acquired, net of fair value of liabilities assumed in connection with mergers and acquisitions. The goodwill balance includes $453 million recorded in connection with the acquisition of Pacific Premier in 2025.

The Company performed its annual impairment assessment as of October 31, 2025 and concluded that there was no impairment. As of March 31, 2026, it was determined there were no events or circumstances which would more likely than not reduce the fair value of our reporting unit below its carrying amount.

Core deposit intangibles were determined based on the present value of the expected cost savings attributable to the core deposit funding relative to an alternative source of funding. Intangible assets are being amortized on an accelerated basis over a period of 10 years. No impairment losses have been recognized in the periods presented.

The following table summarizes other intangible assets as of the dates presented:

**Note 7 – Borrowings**

The Bank's FHLB advances were $3.4 billion as of March 31, 2026, as compared to $3.2 billion at December 31, 2025. These advances have fixed interest rates ranging from 3.84% to 3.87% and all mature in 2026. The FHLB requires the Bank to maintain a specified level of investment in FHLB stock and to pledge sufficient eligible collateral to support secured borrowings. Refer to Note 4 – *Loans and Leases* for additional information on loans pledged as collateral.

**Note 8 – Commitments and Contingencies**

*Financial Instruments with Off-Balance-Sheet Risk* — The Company's financial statements do not reflect certain commitments and contingent liabilities that arise in the normal course of the Bank's business and may expose the Bank to varying degrees of credit, liquidity, and interest rate risk.

The following table presents a summary of the Bank's commitments and contingent liabilities:

---

| | | |
|:---|:---|:---|
| (in millions) | **March 31, 2026** | **December 31, 2025** |
| Commitments to extend credit | $11928 | $11927 |
| Forward sales commitments | $91 | $74 |
| Commitments to originate residential mortgage loans held for sale | $70 | $39 |
| Standby letters of credit | $429 | $427 |

---

The Bank enters into financial instruments with off-balance sheet credit risk in the normal course of business to meet the financing needs of its customers. These instruments primarily consist of commitments to extend credit and standby letters of credit. Such instruments involve credit and interest-rate risk similar to those associated with the Bank's on-balance sheet lending activities. The contractual or notional amounts of these instruments represent the maximum potential exposure to credit loss in each category.

The Bank's exposure to credit loss in the event of non-performance by the counterparty for commitments to extend credit, standby letters of credit, and other financial guarantees is limited to the contractual notional amount of these instruments. The Bank uses the same credit approval, risk management, and monitoring policies for these off-balance sheet instruments as it does for on-balance sheet financial instruments.

Standby letters of credit and written financial guarantees are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. These guarantees are primarily issued to support public and private borrowing arrangements, including international trade finance, commercial paper, bond financing, and similar transactions. The credit risk associated with issuing letters of credit is substantially similar to the credit risk associated with extending loan facilities to customers. The Bank may require collateral to support these commitments when deemed appropriate, which can include cash, marketable securities, or real estate. There were no financial guarantees in connection with standby letters of credit that the Bank was required to perform on during the three months ended March 31, 2026 and 2025. As of March 31, 2026, approximately $415 million of standby letters of credit were scheduled to expire within one year, with an additional $14 million expiring thereafter.

Residential mortgage loans sold into the secondary market are generally sold with limited recourse to the Company. Under these arrangements, the Company may be obligated to repurchase the loan or otherwise reimburse the investor for losses incurred if a loan experiences an early payment default, fails to meet applicable underwriting or investor guidelines, or is determined to include borrower misrepresentations made prior to closing.

*Legal Proceedings and Regulatory Matters—*The Company is subject to litigation in court and arbitral proceedings, as well as proceedings, investigations, examinations, and other actions brought or considered by governmental and self-regulatory agencies. The Company is party to various pending and threatened claims and legal proceedings arising in the normal course of business activities, some of which involve claims for substantial or uncertain amounts.

As previously disclosed, in 2023 the Bank was informed by one of its technology service providers (the "Vendor") that a widely reported security incident involving MOVEit, a file sharing software used globally by government agencies, enterprise corporations, and financial institutions, resulted in the unauthorized acquisition by a third party of the names and social security numbers or tax identification numbers of certain of the Bank's consumer and small business customers (the "Vendor Incident"). On behalf of the Bank, the Vendor notified affected customers (approximately 429,000), and the Bank and Vendor notified applicable federal and state regulators regarding the Vendor Incident. Subsequently, the Bank was named in a number of putative class action lawsuits related to the Vendor Incident. The lawsuits collectively allege claims for negligence, negligence per se, breach of contract, breach of implied contract, breach of third-party beneficiary contract, breach of fiduciary duty, invasion of privacy, breach of the covenant of good faith and fair dealing, unjust enrichment, and violation of certain state statutes. Given the large number of federal cases throughout the United States (including those involving the Bank), on October 4, 2023 the United States Judicial Panel on Multidistrict Litigation initiated a multidistrict litigation ("MDL") to consolidate such cases – In Re: MOVEit Customer Data Security Breach Litigation, MDL No. 3083 – in the United States District Court for the District of Massachusetts (MDL No. 1:23-md-03083-ADB-PGL). The Bank has engaged defense counsel and intends to vigorously defend against these lawsuits and any similar or related lawsuits or claims. The Bank has notified relevant insurance carriers and business counterparties and continues to reserve all of its relevant rights to indemnity, defense, contribution, and other relief in connection with these matters.

At least quarterly, liabilities and contingencies are assessed in connection with all outstanding or new legal matters, utilizing the most recent information available. If it is determined that a loss from a matter is probable and that the amount of the loss can be reasonably estimated, an accrual for the loss is established. Once established, each accrual is adjusted as appropriate to reflect any subsequent developments in the specific legal matter. It is inherently difficult to determine whether any loss is probable or even possible. It is also inherently difficult to estimate the amount of any loss and there may be matters for which a loss is probable or reasonably possible but not currently estimable. Actual losses may be in excess of any established accrual or the range of reasonably possible loss. Management's estimate will change from time to time. For matters where a loss is not probable, or the amount of the loss cannot be estimated, no accrual is established.

The resolution and the outcome of legal claims are unpredictable, exacerbated by factors including the following: damages sought are unsubstantiated or indeterminate; it is unclear whether a case brought as a class action will be allowed to proceed on that basis; discovery or motion practice is not complete; the proceeding is not yet in its final stages; the matters present legal uncertainties; there are significant facts in dispute; there are a large number of parties, including multiple defendants; or there is a wide range of potential results. Any estimate or determination relating to the future resolution of legal and regulatory matters is uncertain and involves significant judgment. The Company is usually unable to determine whether a favorable or unfavorable outcome is remote, reasonably likely or probable, or to estimate the amount or range of a probable or reasonably likely loss until relatively late in the process.

Although there can be no assurance as to the ultimate outcome of a specific legal matter, the Company believes it has meritorious defenses to the claims asserted against us in our currently outstanding legal matters, and the Company intends to continue to vigorously defend ourselves. The Company will consider settlement of legal matters when, in management's judgment, it is in the best interests of the Company and its shareholders.

Based on information currently available, advice of counsel, available insurance coverage, and established reserves, the Company believes that the eventual outcome of the actions against us will not have a material adverse effect on the Company's consolidated financial statements. However, it is possible that the ultimate resolution of a matter, if unfavorable, may be material to the Company's results of operations for any particular reporting period.

*Concentrations of Credit Risk*—The Bank extends real estate mortgage, real estate construction, commercial, agricultural and installment loans and leases to customers primarily located in Arizona, California, Colorado, Idaho, Nevada, Oregon, Utah, and Washington. Based on management's judgment, a concentration of credit risks exists in real estate-related loans, which represented approximately 75% and 76% of the Bank's loan and lease portfolio as of March 31, 2026 and December 31, 2025, respectively. CRE concentrations are actively managed to promote geographic and business diversification, primarily within the Bank's footprint. The multifamily portfolio, including construction loans, represented approximately 24% of the total loan portfolio as of both March 31, 2026 and December 31, 2025. The office portfolio represented approximately 7% and 8% of the total loan portfolio as of March 31, 2026 and December 31, 2025, respectively. Although management believes such concentrations do not expose the Bank to risks beyond normal collectability, a substantial decline in the economy in general, material increases in interest rates, changes in tax policies, tightening of credit or refinancing markets, or declines in real estate values within the Bank's primary market areas, could have an adverse impact on the repayment of these loans. Primary sources of repayment for a majority of these loans include personal and business cash flows, proceeds from the sale of real property, and proceeds from refinancing.

The Bank also recognizes the credit risks inherent with transactions involving other depository institutions. To mitigate these risks, the Bank has established standards for the selection of correspondent banks and internal limits on exposure to any single correspondent. In addition, the Bank maintains an investment policy that sets forth limitations that apply to all investments with respect to credit rating and concentrations with an issuer.

**Note 9 – Derivatives** 

The Company is exposed to certain risks arising from both its business and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of its assets and liabilities as well as the use of derivative financial instruments. Specifically, the Company enters into interest rate-based derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts. The Company's derivative financial instruments are used to manage differences in the amount, timing and duration of the Company's known or expected cash receipts and its known or expected cash payments principally related to the Company's loan portfolio. These derivative financial instruments are not designated as accounting hedges and are recorded at fair value, with changes recognized in earnings.

***Interest Rate Swaps***

The Company's primary derivative activity consists of interest rate swaps executed with commercial borrowers to facilitate their risk management strategies. These swaps are economically hedged through offsetting swaps with third parties, minimizing net exposure. As of March 31, 2026, the Company had interest rate swap assets with notional amounts of $4.4 billion and interest rate swap liabilities with notional amounts of $4.5 billion related to this program, compared with notional amounts of $4.5 billion for both assets and liabilities as of December 31, 2025. Collateral posted under these arrangements for initial margins with its clearing houses and is required to post collateral against its obligations under these interest rate swaps totaled $89 million and $93 million at March 31, 2026 and December 31, 2025, respectively. Centrally cleared swaps are cleared through the Chicago Mercantile Exchange and London Clearing House, with variation margin treated as settlement of mark-to-market exposure. Variation margin netting adjustments were $100 million and $98 million at March 31, 2026 and December 31, 2025, respectively. The Company also enters into bilateral Term SOFR swaps that are not clearable; these require daily cash collateral exchanges but no initial margin.

***Forward Delivery Contracts***

To hedge interest rate risk on mortgage loans held for sale and interest rate lock commitments, the Company enters into forward delivery contracts to sell residential mortgage loans or mortgage-backed securities at specified prices and dates. Credit risk is limited to the replacement cost of contracts in a gain position, and no counterparty defaults occurred in the three months ended March 31, 2026 and 2025. Market risk is managed by monitoring positions and offsetting differences between customer commitments and broker-dealer contracts. If commitments exceed available loans, the Company settles by paying or receiving a fee equal to the change in market value. As of March 31, 2026 and December 31, 2025, mortgage loan origination commitments totaled $70 million and $39 million, respectively, and forward sales commitments totaled $91 million and $74 million, respectively.

***Other Derivative Contracts***

The Company uses interest rate futures and forward-settling mortgage-backed securities to hedge interest rate risk on mortgage servicing rights. As of March 31, 2026, the Bank had $214 million notional of interest rate futures contracts and $33 million of mortgage-backed securities, compared to $211 million and $34 million, respectively, as of December 31, 2025. The Company also provides foreign currency hedging services to customers, offsetting these positions with third-party banks to limit risk exposure.

The Company's derivatives are included in other assets or other liabilities on the Consolidated Balance Sheets and measured at fair value.

**Note 10 – Earnings Per Common Share and Shareholders' Equity** 

The Company applies the two-class method of computing basic and diluted EPS. Under the two-class method, net income is allocated between common stock and participating securities based on their respective dividend rights and participation in undistributed earnings. In connection with the Pacific Premier acquisition, the Company issued certain RSAs under share-based compensation plans that qualify as participating securities. Participating securities had no impact on EPS for the periods ended March 31, 2026 and 2025.

Basic EPS is calculated by dividing net income attributable to common shareholders by the weighted-average number of common shares outstanding, excluding participating securities. Diluted EPS reflects the weighted-average number of common shares outstanding adjusted for the effect of potentially dilutive securities, excluding participating securities and any instruments that are anti-dilutive.

The following table presents the computation of basic and diluted earnings per common share for the periods indicated:

***Share Repurchase Program***

On October 29, 2025, the Company's Board of Directors approved a share repurchase program authorizing the repurchase of up to $700 million of the Company's common stock through November 30, 2026. During the three months ended March 31, 2026, the Company repurchased 6.5 million shares for an aggregate purchase price of $200 million, at an average price of $30.74 per share. There were no share repurchases during the three months ended March 31, 2025.

The following methods were used to estimate the fair value of each class of financial instrument that is carried at fair value in the tables above:

*Securities*— Fair values for investment securities are based on quoted market prices when available or through the use of alternative approaches, such as matrix or model pricing, or broker indicative bids, when market quotes are not readily accessible or available. Management periodically reviews the pricing information received from the third-party pricing service and compares it to a secondary pricing service, evaluating significant price variances between services to determine an appropriate estimate of fair value to report.

*Loans Held for Sale*— Fair value for residential mortgage loans originated as held for sale is determined based on quoted secondary market prices for similar loans, including the implicit fair value of embedded servicing rights. For loans not originated as held for sale, these loans are accounted for at lower of cost or market, with the fair value estimated based on the expected sales price.

*Loans and leases*— Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type, including commercial, real estate, and consumer loans. Each loan category is further segregated by fixed and adjustable-rate loans. The fair value of loans is calculated by discounting expected cash flows at rates at which similar loans are currently being made. This model is periodically validated by an independent model validation group. These amounts are discounted further by embedded probable losses expected to be realized in the portfolio. For loans originated as held for sale and transferred into loans held for investment, the fair value is determined based on quoted secondary market prices for similar loans.

*Residential Mortgage Servicing Rights*— The fair value of MSR is estimated using a DCF model. Assumptions used include market discount rates, anticipated prepayment speeds, delinquency and foreclosure rates, and ancillary fee income net of servicing costs. This model is periodically validated by an independent model validation group. The model assumptions and the MSR fair value estimates are also compared to observable trades of similar portfolios as well as to MSR broker valuations and industry surveys, as available. Management believes the significant inputs utilized are indicative of those that would be used by market participants. The amount of contractually specified servicing fees, late fees, and ancillary fees earned, which is recorded in residential mortgage banking revenue, was $6 million for both the three months ended March 31, 2026 and 2025.

*Junior Subordinated Debentures*— The fair value of junior subordinated debentures is estimated using an income approach valuation technique. The significant unobservable input utilized in the estimation of fair value of these instruments is the credit risk adjusted spread. The credit risk adjusted spread represents the non-performance risk of the liability, contemplating the inherent risk of the obligation. The Company periodically utilizes a valuation firm to determine or validate the reasonableness of inputs and factors that are used to determine the fair value. The ending carrying (fair) value of the junior subordinated debentures measured at fair value represents the estimated amount that would be paid to transfer these liabilities in an orderly transaction among market participants. Due to credit concerns in the capital markets and inactivity in the trust preferred markets that have limited the observability of market spreads, the Company has classified this as a Level 3 fair value measurement.

*Derivative Instruments*— Derivatives include interest rate swaps, forward sales commitments, foreign currency derivatives, interest rate futures, and interest rate lock commitments. The fair values of these instruments generally fluctuate with changes in market interest rates. Interest rate swaps, forward sales commitments, and foreign currency derivatives are valued using dealer quotes and secondary market sources and are classified as Level 2 fair value measurements. Interest rate futures are exchange-traded derivatives, valued at fair value using quoted settlement prices from the exchange, and are classified as Level 1. Interest rate lock commitments use a pull-through rate that is considered an unobservable input, so these are classified as Level 3 fair value measurements.

***Assets and Liabilities Measured at Fair Value Using Significant Unobservable Inputs (Level 3)***

The following table provides a description of the valuation technique, significant unobservable inputs, and qualitative information about the unobservable inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a recurring basis as of the dates presented:

---

| **Financial Instrument** | **Fair Value** <br>**(in millions)** | **Valuation Technique** | **Unobservable Input** | **Range of Inputs** | **Weighted Average** |
| **March 31, 2026** | | | | | |
| **Assets:** | | | | | |
| Residential mortgage servicing rights | $105 | Discounted cash flow | Constant prepayment rate | 5.68% - 29.31% | 7.66% |
|  |  |  | Discount rate | 9.50% - 16.33% | 10.18% |
| **Liabilities:** |  |  |  |  |  |
| Junior subordinated debentures | $333 | Discounted cash flow | Credit spread | 2.15% - 4.06% | 3.08% |
| **Financial Instrument** | **Fair Value** <br>**(in millions)** | **Valuation Technique** | **Unobservable Input** | **Range of Inputs** | **Weighted Average** |
| **December 31, 2025** |  |  |  |  |  |
| **Assets:** |  |  |  |  |  |
| Residential mortgage servicing rights | $99 | Discounted cash flow | Constant prepayment rate | 5.76% - 30.21% | 8.26% |
|  |  |  | Discount rate | 9.50% - 16.30% | 10.20% |
| **Liabilities:** |  |  |  |  |  |
| Junior subordinated debentures | $338 | Discounted cash flow | Credit spread | 1.82% - 3.97% | 2.86% |

---

Generally, increases in the constant prepayment rate or the discount rate utilized in the fair value measurement of the residential mortgage servicing rights will result in a decrease in fair value. Conversely, decreases in the constant prepayment rate or the discount rate will result in an increase in fair value.

Management believes that the credit risk adjusted spread utilized in the fair value measurement of the junior subordinated debentures carried at fair value is indicative of the non-performance risk premium a willing market participant would require under current market conditions, which is an inactive market. Generally, an increase in the credit spread will result in a decrease in the estimated fair value. Conversely, a decrease in the credit spread will result in an increase in the estimated fair value.

---

Changes in residential mortgage servicing rights carried at fair value are recorded in residential mortgage banking revenue within non-interest income.

The contractual interest expense on the junior subordinated debentures is recorded on an accrual basis as interest on junior subordinated debentures within interest expense. Settlements related to the junior subordinated debentures represent the payment of accrued interest that is embedded in the fair value of these liabilities. The change in fair value of junior subordinated debentures is attributable to the change in the instrument specific credit risk; accordingly, the unrealized gains of $4 million for the three months ended March 31, 2026 were recorded net of tax as other comprehensive income of $3 million. Unrealized gains of $10 million were recorded net of tax as other comprehensive income of $8 million for the three months ended March 31, 2025. The change recorded for the three months ended March 31, 2026 was driven by higher market interest rates and wider credit spreads, partially offset by higher expected cash flows.

***Fair Value of Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis*** 

From time to time, certain assets are measured at fair value on a nonrecurring basis. These adjustments to fair value generally result from the application of lower-of-cost-or-market accounting or write-downs of individual assets due to impairment, typically on collateral-dependent loans. The following tables present information about the Company's assets and liabilities measured at fair value on a nonrecurring basis for which a nonrecurring change in fair value was recorded during the reporting period. The amounts disclosed below represent the fair values at the time the nonrecurring fair value measurements were made, and not necessarily the fair value as of the dates reported upon.

The following provides a description of the valuation technique and inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a nonrecurring basis. Unobservable inputs and qualitative information about the unobservable inputs are not presented as the fair value is determined by third-party information for loans and leases.

The loans and leases amounts above represent collateral-dependent loans and leases that have been adjusted to fair value. When a loan or non-homogeneous lease is identified as collateral-dependent, the Bank measures the impairment using the current fair value of the collateral, less estimated selling costs. Depending on the characteristics of a loan or lease, the fair value of collateral is generally estimated by obtaining external appraisals, but in some cases the value of the collateral may be estimated as having little to no value. When a homogeneous lease or equipment finance agreement becomes 181 days past due, it is determined that the collateral has little to no value. If it is determined that the value of the collateral-dependent loan or lease is less than its recorded investment, the Bank recognizes this impairment and adjusts the carrying value of the loan or lease to fair value, less costs to sell, through the ACL. The loss represents charge-offs on collateral-dependent loans and leases for fair value adjustments based on the fair value of collateral.

***Fair Value Option***

The following table presents the difference between the aggregate fair value and the aggregate unpaid principal balance of loans held for sale and loans held for investment accounted for under the fair value option as of the dates presented:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| | **March 31, 2026** | **March 31, 2026** | **March 31, 2026** | **December 31, 2025** | **December 31, 2025** | **December 31, 2025** |
| (in millions) | **Fair Value** | **Aggregate Unpaid Principal Balance** | **Fair Value Less Aggregate Unpaid Principal Balance** | **Fair Value** | **Aggregate Unpaid Principal Balance** | **Fair Value Less Aggregate Unpaid Principal Balance** |
| Loans held for sale | $81 | $80 | $1 | $142 | $156 | $(14) |
| Loans held for investment | $79 | $85 | $(6) | $78 | $82 | $(4) |

---

The Bank elected to measure certain residential mortgage loans held for sale under the fair value option, with interest income on these loans held for sale reported in interest and fees on loans and leases on the Consolidated Statements of Income. This reduces certain timing differences and better matches changes in the value of these assets with changes in the value of derivatives used as economic hedges for these assets. Residential mortgage loans held for sale accounted for under the fair value option are measured initially at fair value with subsequent changes in fair value recognized in earnings. Gains and losses from such changes in fair value are reported as a component of residential mortgage banking revenue. For the three months ended March 31, 2026, the Company recorded a net increase in fair value of $15 million, as compared to a net increase in fair value of $1 million for the three months ended March 31, 2025.

Management's intent to sell certain residential mortgage loans classified as held for sale may change over time due to factors including changes in overall market liquidity or changes in characteristics specific to certain loans held for sale. Consequently, these loans may be reclassified as loans held for investment and maintained in the Bank's loan portfolio. In the event that loans currently classified as held for sale are reclassified as loans held for investment, the loans will continue to be measured at fair value. Gains and losses from changes in fair value for these loans are reported in earnings as a component of other income and interest income on these loans are reported in interest and fees on loans and leases on the Consolidated Statements of Income. For the three months ended March 31, 2026, the Company recorded a net decrease in fair value of $2 million, as compared to a net increase in fair value of $7 million for the three months ended March 31, 2025.

The Company selected the fair value measurement option for certain junior subordinated debentures originally issued by UHC prior to its merger with Columbia (the Umpqua Statutory Trusts) and for junior subordinated debentures acquired by UHC from Sterling Financial Corporation prior to UHC's merger with Columbia, with changes in fair value recognized as a component of other comprehensive income. The remaining junior subordinated debentures were acquired through business combinations and were measured at fair value at the time of acquisition and subsequently measured at amortized cost.

**Note 12 – Income Taxes and Investment Tax Credits**

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and in most states. The Company believes it is more likely than not that it will be able to fully realize the benefit of its federal and state NOL and tax carryforwards and has not provided a valuation allowance against its deferred tax assets.

As of March 31, 2026, the Company had a net deferred tax asset of $368 million, which is included in other assets on the Consolidated Balance Sheets and includes $5 million of federal and state NOL carry-forwards that will begin to expire in 2027.

The Company recorded income tax expense of $63 million and $37 million for the three months ended March 31, 2026 and 2025, respectively, representing effective tax rates of 24.7% and 30.1%, respectively. The effective tax rates differed from the statutory federal income tax rate primarily due to the impact of state income taxes, non-deductible compensation, non-deductible FDIC assessments, and income on tax-exempt investment securities and loans. The change to the effective tax rate for the three months ended March 31, 2026, as compared to the corresponding period in the prior year, was primarily attributable to a decrease in non-deductible compensation, including severance-related items incurred in the prior-year period.

**Investment Tax Credits**

The Company is involved in various entities that are considered to be variable interest entities, which are primarily related to investments promoting affordable housing and trust preferred securities. The Company is not required to consolidate variable interest entities in which it has concluded it does not have a controlling financial interest, and thus not the primary beneficiary. In such cases, the Company does not have both the power to direct the entities' most significant activities and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the variable interest entity. The maximum exposure to loss in the LIHTC is the amount of equity invested and credit extended by the Company.

***Affordable Housing Tax Credit Investments***

The Company makes certain equity investments in various limited partnerships that sponsor affordable housing projects; the purpose of these investments is to achieve a satisfactory return on capital, to facilitate the sale of additional affordable housing product offerings, and to assist in achieving goals associated with the Community Reinvestment Act. The primary activities of the limited partnerships include the identification, development, and operation of multi-family housing that is leased to qualifying residential tenants.

The Company's investments in these entities generate a return primarily through the realization of federal income tax credits and other tax benefits, such as tax deductions from operating losses of the investments, over specified time periods. These tax credits and deductions are recognized as a reduction to income tax expense.

The Company records the investments in affordable housing partnerships of $341 million and $344 million as of March 31, 2026 and December 31, 2025, respectively, as a component of other assets on the Consolidated Balance Sheets and uses the proportional amortization method to account for the investments. The Company's unfunded capital commitments to these investments were $127 million and $140 million as of March 31, 2026 and December 31, 2025, respectively, which are recorded as a component of other liabilities on the Consolidated Balance Sheets. Amortization related to these investments is recorded as a component of the provision for income taxes on the Consolidated Statements of Income.

**Note 13 – Segment Reporting**

The Company has one operating and reportable segment based on the products and services offered, primarily banking operations as well as the operations, technology, and administrative functions of the Bank and Holding Company. The Company primarily derives revenue from banking operations by providing consumer and residential real estate loans, commercial lending products, deposit products, and treasury and wealth management services. The Company's primary market areas are in Arizona, California, Colorado, Idaho, Nevada, Oregon, Texas, Utah, and Washington and it manages the business activities on a consolidated basis. The accounting policies of the Bank are the same as those described in Note 1 - *Summary of Significant Accounting Policies* of the Notes to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

The Company's CODM is the Chief Executive Officer. The CODM evaluates performance and makes decisions regarding the allocation of operating and capital based on consolidated net income, as reported on the Consolidated Statements of Income. The CODM also reviews total consolidated assets, as reported on the Consolidated Balance Sheets, as a measure of segment assets.

The CODM uses consolidated net income to evaluate income generated from segment assets in making decisions about the allocation of operating and capital resources. Consolidated net income is also used by the CODM to monitor budget versus actual results and in competitive analysis by benchmarking to the Company's competitors. The competitive analysis along with the monitoring of budgeted versus actual results are used in assessing performance of the segment and in establishing management's compensation. The CODM is regularly provided with significant segment expense information at a level consistent with that disclosed in the Company's Consolidated Statements of Income.

**Executive Overview** 

***Financial Performance***

*Comparison of current quarter to prior quarter*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Earnings per diluted common share was $0.66 for the three months ended March 31, 2026, as compared to $0.72 for the three months ended December 31, 2025. The decrease was primarily attributable to lower net interest income and non-interest income, as well as a higher provision for credit losses, partially offset by lower non-interest expense. The decrease in net interest income reflects the absence of the prior quarter's benefit from the time deposit premium amortization, as well as lower average interest-earning asset balances, partially offset by an improved mix of higher yielding loans and investment securities, as we continue to optimize our balance sheet. The decrease in non-interest expenses was largely driven by lower merger and restructuring expenses related to the acquisition of Pacific Premier.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net interest margin, on a tax-equivalent basis, was 3.96% for the three months ended March 31, 2026, as compared to 4.06% for the three months ended December 31, 2025. The decline primarily reflects the absence of the $12 million of time-deposit premium amortization associated with the Pacific Premier acquisition that benefited the prior quarter. Lower yields on loans and cash following reductions to the federal funds rate during the fourth quarter of 2025 were offset by lower deposit costs related to the rate reductions and continued improvement in the Company's funding mix, including a lower proportion of higher-cost brokered deposits. The average cost of interest-bearing deposits declined by 4 basis points to 2.04%, reflecting proactive deposit pricing actions and a favorable change in deposit mix. Overall, the cost of interest-bearing liabilities declined to 2.24%, a 3-basis-point decrease from the prior quarter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Non-interest income was $83 million for the three months ended March 31, 2026, as compared to $90 million for the three months ended December 31, 2025. Quarterly changes in fair value adjustments and MSR hedging activity, driven by interest-rate movements, resulted in a net fair-value gain of $2 million during the quarter, unchanged from the prior quarter. The remaining change in non-interest income primarily reflects lower swap, syndication, and international banking revenue following stronger levels of customer activity in the prior quarter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Non-interest expense was $394 million for the three months ended March 31, 2026, representing a decrease of $18 million as compared to the three months ended December 31, 2025. The decrease was primarily due to a $15 million reduction in merger and restructuring expenses, as well as the realization of acquisition-related cost savings with the Pacific Premier acquisition.

*Comparison of current year-to-date to prior year period*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Earnings per diluted common share was $0.66 for the three months ended March 31, 2026, as compared to $0.41 for the three months ended March 31, 2025. The increase primarily reflects higher net income driven by the acquisition of Pacific Premier and continued improvements in our balance sheet's mix of assets and liabilities, partially offset by an increase in weighted-average diluted common shares outstanding following the issuance of shares in connection with the Pacific Premier acquisition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net interest margin, on a tax-equivalent basis, was 3.96% for the three months ended March 31, 2026, as compared to 3.60% for the three months ended March 31, 2025. The increase was primarily driven by lower funding costs and benefits of balance sheet optimization, including a shift toward lower-cost customer deposits and reduced reliance on high-cost wholesale funding sources. These improvements were partially offset by lower earning-asset yields, given reductions to the federal funds rate during 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Non-interest income was $83 million for the three months ended March 31, 2026, as compared to $66 million for the three months ended March 31, 2025. The increase was primarily driven by higher financial services and trust revenue reflecting the combined operations following the acquisition of Pacific Premier, as well as growth in customer-related fee income. Changes in fair value adjustments and hedges resulted in a net fair value gain of $2 million related mainly to loans held for investment at fair value and MSR fair value and hedge changes for the three months ended March 31, 2026, compared to a net gain of $10 million for the prior-year period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Non-interest expense was $394 million for the three months ended March 31, 2026, as compared to $340 million for the three months ended March 31, 2025. The increase was primarily driven by the combined operations following the Pacific Premier acquisition, including a $10 million increase in merger and restructuring expense to $24 million, as well as higher salaries and employee benefits and increased occupancy and software costs. The first quarter of 2025 included a $55 million legal settlement, which favorably impacted comparability.

*Comparison of current period end to prior year end*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total loans and leases were $47.7 billion as of March 31, 2026, a decrease of $79 million as compared to December 31, 2025. The decrease primarily reflects continued runoff in below-market-rate transactional loans, partially offset by growth in commercial loans, consistent with the Company's balance sheet optimization strategy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total deposits were $53.5 billion as of March 31, 2026, a decrease of $722 million as compared to December 31, 2025. The decrease was largely attributable to an intentional reduction of brokered deposits to reduce reliance on higher-cost funding sources, partially offset by a modest increase in customer deposit balances.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total consolidated assets were $66.0 billion as of March 31, 2026, as compared to $66.8 billion as of December 31, 2025. The decrease primarily reflects balance sheet optimization activity, including a reduction in excess cash balances as we fine-tuned our liquidity management strategy.

***Credit Quality***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Non-performing assets were $264 million, or 0.40% of total assets, as of March 31, 2026, as compared to $200 million, or 0.30% of total assets, as of December 31, 2025. Non-performing loans and leases were $261 million, or 0.55% of total loans and leases, as of March 31, 2026, compared to $198 million, or 0.41% of total loans and leases, as of December 31, 2025. As of March 31, 2026, non-performing loans included $88 million in government guaranteed balances. The increases in non-performing assets and loans primarily reflects adverse performance in a single agricultural industry relationship and is not indicative of broader portfolio deterioration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The ACL was $478 million as of March 31, 2026, a decrease of $7 million from December 31, 2025. The change reflects updated economic forecasts incorporated into the Company's credit loss models, as well as portfolio activity during the period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provision for credit losses was $28 million for the three months ended March 31, 2026, as compared to $23 million for the three months ended December 31, 2025 and $27 million for the three months ended March 31, 2025. The provision reflects changes in economic forecasts used in the ACL methodology.

***Liquidity***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total cash and cash equivalents were $2.1 billion as of March 31, 2026, a decrease of $281 million from December 31, 2025. The decline primarily reflects a reduction in interest-bearing cash balances as the Company optimized on balance sheet liquidity levels during the quarter, consistent with improved liquidity risk metrics compared to the prior year. The Company manages its cash position with a comprehensive liquidity framework designed to maintain a high-quality liquid asset base, fund lending and investment activity, and reduce debt and other non-deposit liabilities when market conditions are favorable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Including secured off-balance sheet lines of credit, total available liquidity was $27.1 billion as of March 31, 2026, representing 41% of total assets, 51% of total deposits, and 129% of estimated uninsured deposits.

***Capital***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company's total risk-based capital ratio was 13.4% and its common equity tier 1 ("CET1") capital ratio was 11.6% as of March 31, 2026. As of December 31, 2025, the Company's total risk-based capital ratio was 13.6% and its CET1 capital ratio was 11.8%. The modest decline in regulatory capital ratios primarily reflects capital actions during the quarter, including common share repurchases, while remaining well in excess of regulatory well-capitalized standards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*•* Columbia declared a quarterly cash dividend of $0.37 per common share, which was paid to shareholders on March 16, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On October 29, 2025, Columbia's Board of Directors authorized the repurchase of up to $700 million of the Company's common stock under a new repurchase plan, which is scheduled to expire on November 30, 2026. During the three months ended March 31, 2026, the Company repurchased 6.5 million shares of common stock for $200 million. The timing and amount of common share repurchases remain subject to senior management discretion and subject to various factors, including, without limitation, Columbia's capital position, financial performance, market conditions, and regulatory considerations. As of March 31, 2026, $400 million remained under the company's existing repurchase authorization.

**Critical Accounting Estimates** 

Our critical accounting estimates are described in detail in the Critical Accounting Estimates section of our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 26, 2026. The consolidated financial statements are prepared in conformity with GAAP and follow general practices within the financial services industry in which the Company operates. This preparation requires management to make estimates, assumptions, and judgments that affect the amounts reported in the financial statements and accompanying notes. These estimates, assumptions, and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, actual results could differ from the estimates, assumptions, and judgments reflected in the financial statements. Certain estimates inherently have a greater reliance on the use of assumptions and judgments and, as such, have a greater possibility of producing results that could be materially different than originally reported. Management believes that the estimate for ACL and business combinations are important to the portrayal of the Company's financial condition and results of operations and require difficult, subjective, or complex judgments. There have been no material changes in the methodology of these estimates during the three months ended March 31, 2026.

**<u>Results of Operations</u>**

Columbia's financial results for periods ended prior to August 31, 2025, the acquisition date for Pacific Premier, reflect Columbia's results only on a standalone basis. Accordingly, Columbia's reported financial results for the first eight months of 2025 include only Columbia's financial results through the closing of the acquisition. As a result, Columbia's financial results for the three months ended March 31, 2026, may not be directly comparable to results reported for periods prior to the acquisition or to future periods that fully reflect the combined operations.

*Comparison of current quarter to prior quarter*

The Company reported net income of $192 million for the three months ended March 31, 2026, compared to $215 million for the three months ended December 31, 2025. The decrease was primarily attributable to a $33 million decrease in net interest income, partially offset by an $18 million decrease in non-interest expense. The decrease in net interest income reflects lower average interest-earning asset balances, partially offset by an improved mix of higher-yielding loans and investment securities. The decline also reflects a $12 million benefit to interest expense related to the amortization of a premium for Pacific Premier's time deposits and $5 million in interest income related to an accelerated loan repayment in the three months ended December 31, 2025, that did not recur in the current quarter. The decrease in non-interest expense reflects lower merger and restructuring expenses, as well as cost savings related to the Pacific Premier acquisition. Management expects merger-related expenses to continue to decline as integration activities are completed, and all previously disclosed cost savings related to the acquisition are expected to be realized by June 30, 2026.

*Comparison of current year-to-date to prior year period*

For the three months ended March 31, 2026, the Company had net income of $192 million, compared to $87 million for the same period in the prior year. The increase primarily reflects increases in net interest income and non-interest income of $169 million and $17 million, respectively, driven by the acquisition of Pacific Premier, which did not contribute to the results in the prior-year period, and our success replacing transactional loans and wholesale funding sources with relationship-centric business that contributes to loans, deposits, and recurring fee income streams, improving our profitability. These increases were partially offset by higher non-interest expense of $54 million and income tax expense of $26 million. The increase in non-interest expense reflects higher merger and restructuring expense, as well as increased salaries and employee benefits and occupancy and software costs associated with the Pacific Premier acquisition, partially offset by a $55 million accrual for a legal settlement recorded in the prior-year period, which did not repeat. The increase in income tax expense primarily reflects higher pre-tax income resulting from the acquisition.

The following table presents the return on average assets (GAAP), average common shareholders' equity (GAAP), and average tangible common shareholders' equity (non-GAAP) for the periods indicated. For each period presented, the table includes the calculated ratios based on reported net income. To the extent return on average common shareholders' equity is used to compare our performance with other financial institutions that do not have merger and acquisition-related intangible assets, management believes it is also meaningful to consider return on average tangible common shareholders' equity. This measure is useful for evaluating performance as it reflects returns available to common shareholders excluding the impact of intangible assets and their related amortization. Return on average tangible common shareholders' equity is calculated by dividing net income by average shareholders' common equity less average goodwill and other intangible assets, net (excluding MSR). This measure is considered a non-GAAP financial measure and should be viewed in conjunction with the return on average common shareholders' equity. Return on average tangible common shareholders' equity is also used as a performance metric in the Company's executive incentive compensation program.

| Average tangible common shareholders' equity | $5611 | $5597 | $3715 |

---

In addition, management believes *tangible common equity* and the *tangible common equity ratio* are meaningful measures of the Company's capital adequacy. Management believes that excluding certain intangible assets from the calculation of tangible common equity and the tangible common equity ratio provides a meaningful basis for period-to-period and company-to-company comparisons and assists investors in evaluating the Company's operating performance and capital position. Tangible common equity is calculated as total shareholders' equity less goodwill and other intangible assets, net (excluding MSR). Tangible assets are calculated as total assets less goodwill and other intangible assets, net (excluding MSR). The tangible common equity ratio is calculated as tangible common shareholders' equity divided by tangible assets. Tangible common equity and the tangible common equity ratio are considered non-GAAP financial measures and should be viewed in conjunction with total shareholders' equity and the total shareholders' equity ratio.

The following table provides a reconciliation of ending shareholders' equity (GAAP) to ending tangible common equity (non-GAAP), and ending assets (GAAP) to ending tangible assets (non-GAAP) as of the dates presented:

Non-GAAP financial measures have inherent limitations, are not determined in accordance with GAAP, and may not be comparable to similarly titled measures used by other companies. In addition, these measures are not audited or reviewed. While management believes that non-GAAP financial measures are useful to investors and other stakeholders in evaluating the Company's performance, they should not be considered in isolation or as a substitute for results reported in accordance with GAAP.

**Net Interest Income** 

*Comparison of current quarter to prior quarter*

Net interest income for the three months ended March 31, 2026 was $594 million, a decrease of $33 million compared to the three months ended December 31, 2025. The decrease was primarily driven by a $42 million decrease in interest income, reflecting lower average interest-earning asset balances and lower yields on loans and cash following reductions in the federal funds rate during the fourth quarter of 2025. These impacts were partially offset by favorable asset mix, including a higher proportion of higher-yielding loans and investment securities. The decrease in interest income was partially offset by a $9 million decrease in interest expense, reflecting our active management of deposit rates ahead of and following reductions to the federal funds rate. Our actions were partially offset by the absence of the prior quarter's $12 million amortization of a premium related to Pacific Premier's time deposits, which concluded on December 31, 2025 and provided a benefit to interest expense during the fourth quarter of 2025, as well as $5 million in interest income related to an accelerated loan repayment in the three months ended December 31, 2025, that did not recur in the current quarter.

Net interest margin, calculated as net interest income as a percentage of average interest-earning assets on a fully tax-equivalent basis, was 3.96% for the three months ended March 31, 2026, as compared to 4.06% for the three months ended December 31, 2025. The decrease primarily reflects the absence of the prior quarter's 8-basis point benefit from the time deposit premium amortization and the absence of a 3-basis point benefit related to an accelerated loan repayment during the prior quarter. Lower earning asset yields resulting from recent reductions in the federal funds rate were offset by correspondingly lower deposit costs and continued improvement in the Company's funding mix, including a lower proportion of higher-cost brokered deposits.

The cost of interest-bearing deposits for the three months ended March 31, 2026 was 2.04%, a decrease of 4 basis points compared to the three months ended December 31, 2025. The decrease reflects proactive management of deposit rates surrounding the Federal Reserve's October and December rate cuts, as well as a favorable change in deposit mix, including a reduction in higher-cost brokered deposits. The prior quarter's cost of interest-bearing deposits benefited from $12 million of amortization of premiums on Pacific Premier's time deposits, which concluded on December 31, 2025 and provided a 12-basis point benefit to the cost of interest-bearing deposits during the fourth quarter of 2025. The cost of interest-bearing liabilities for the three months ended March 31, 2026 was 2.24%, a decrease of 3 basis points compared to the three months ended December 31, 2025. The decrease reflects the same underlying drivers as interest-bearing deposits, partially offset by higher average borrowings for the three months ended March 31, 2026 relative to prior quarter, as balances increased late in December, due to an expected decline in customer deposit balances, given typical behavior related to year-end spending and business distributions.

*Comparison of current year-to-date to prior year period*

Net interest income for the three months ended March 31, 2026 was $594 million, an increase of $169 million compared to the three months ended March 31, 2025. The increase was primarily driven by an increase of $168 million in interest income, reflecting higher average loans and leases balances following the acquisition of Pacific Premier, with acquired balances recorded at fair value as of August 31, 2025.

Net interest margin, calculated on a fully tax-equivalent basis, was 3.96% for the three months ended March 31, 2026, as compared to 3.60% for the three months ended March 31, 2025. The increase was primarily attributable to lower funding costs and a favorable balance sheet mix shift toward lower-cost customer deposits and away from higher-cost wholesale funding sources, which include borrowings and brokered deposits. The cost of interest-bearing liabilities was 2.24% for the three months ended March 31, 2026, compared to 2.80% for the three months ended March 31, 2025, a decrease of 56 basis points. The decrease was driven primarily by reductions in the federal funds rate and a continued optimization of the Company's funding mix. These benefits were partially offset by slightly lower earning-asset yields. The yield on earning assets was 5.44% for the three months ended March 31, 2026, compared to 5.49% for the three months ended March 31, 2025, a decrease of 5 basis points. The yield on loans and leases was 5.78% for the three months ended March 31, 2026, as compared to 5.92% for the three months ended March 31, 2025, a decrease of 14 basis points, reflecting the declining rate environment during 2025, partially offset by higher average loans and leases balances related to the Pacific Premier acquisition. An increase in the yield on investment securities reflected higher-yielding new purchases, including acquired securities recorded at fair value in connection with the Pacific Premier acquisition, replacing principal paydowns from lower-yielding securities, partially offsetting the decrease in the yield on loans and leases.

During 2025, the Federal Reserve reduced the target range for the federal funds rate by an aggregate of 0.75% through a series of 0.25% reductions primarily implemented in the fourth quarter. The target range remained unchanged during the first quarter of 2026. As of March 31, 2026, the balance sheet remains modestly liability sensitive. Management expects customer deposit balance trends and continued optimization of the funding mix to be key drivers of net interest margin performance, as the Company continues to target a lower reliance on wholesale funding sources, including FHLB advances and brokered deposits.

The following tables present condensed average balance sheet information, including interest income and yields on average interest-earning assets, as well as interest expense and rates paid on average interest-bearing liabilities, for the periods presented:

**Provision for Credit Losses** 

*Comparison of current quarter to prior quarter*

The Company had a $28 million provision for credit losses for the three months ended March 31, 2026, as compared to a $23 million provision for the three months ended December 31, 2025. The increase was primarily driven by credit migration trends and updated economic forecasts incorporated into the Company's credit loss models. As an annualized percentage of average outstanding loans and leases, the provision for credit losses recorded for the three months ended March 31, 2026 was 0.24%, as compared to 0.19% for the three months ended December 31, 2025.

For the three months ended March 31, 2026 and December 31, 2025, net charge-offs were $35 million and $30 million, respectively. As an annualized percentage of average outstanding loans and leases, net charge-offs for the three months ended March 31, 2026 were 0.30%, as compared to 0.25% for the three months ended December 31, 2025. Net charge-offs within the FinPac portfolio were $14 million for the three months ended March 31, 2026 and December 31, 2025. Excluding the FinPac portfolio, net charge-offs were $21 million, as compared to $16 million in the prior period.

*Comparison of current year-to-date to prior year period*

The Company had a $28 million provision for credit losses for the three months ended March 31, 2026, as compared to $27 million for the three months ended March 31, 2025. The increase reflects loan portfolio runoff, credit migration trends, and updated economic forecasts incorporated into the Company's credit loss models. As an annualized percentage of average outstanding loans and leases, the provision for credit losses recorded for the three months ended March 31, 2026 was 0.24%, as compared to 0.29% for the three months ended March 31, 2025.

<u>[**Table of Contents**](#i2afd483bd7254a5f9ef1108885030a3f_430)</u>

For the three months ended March 31, 2026, net charge-offs were $35 million, as compared to $30 million for the three months ended March 31, 2025. As an annualized percentage of average outstanding loans and leases, net charge-offs for the three months ended March 31, 2026 were 0.30%, as compared to 0.32% for the three months ended March 31, 2025. Net charge-offs in the FinPac portfolio were $14 million for the three months ended March 31, 2026, as compared to $17 million for the three months ended March 31, 2025, which is reflective of continued improvement of the lease portfolio. Net charge-offs for the Bank were $21 million and $13 million for the three months ended March 31, 2026 and 2025, respectively.

Generally, loans placed on non-accrual status do not carry an ACL as they are typically written down to their net realizable value or charged off. However, for homogeneous leases and equipment finance agreements, net realizable value is determined using the LGD calculated by the Company's CECL model. As a result, homogeneous leases and equipment finance agreements classified as non-accrual continue to carry an ACL until they become 181 days past due, at which time they are charged off. The non-accrual leases and equipment finance agreements of $19 million as of March 31, 2026 have a related ACL of $17 million, with the remaining loans written-down to the estimated fair value of the underlying collateral, net of estimated costs to sell, and are expected to be resolved with no additional material loss, absent further decline in market prices.

**Non-Interest Income** 

The following table presents the key components of non-interest income and the related dollar and percentage change from period to period:

*Comparison of current quarter to prior quarter*

Customer fee income decreased during the three months ended March 31, 2026, reflecting lower service charges on deposits, card-based fees, and other income. The decrease was primarily driven by particularly strong performance in swap, syndication, and international banking revenue during the three months ended December 31, 2025, as well as an expected seasonal slowdown in customer activity that is typical for the first quarter, partially attributable to two fewer days in the period.

Residential mortgage banking revenue increased during the three months ended March 31, 2026. The increase was primarily driven by a $6 million gain on the fair value of the MSR asset related to changes in valuation inputs and assumptions, compared to a loss of $1 million for the three months ended December 31, 2025.

*Comparison of current year-to-date to prior year period*

Financial services and trust revenue increased during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. The increase reflects the combined operations following the acquisition of Pacific Premier, which contributed to higher transaction volumes and an expanded client base. In addition, the Pacific Premier acquisition significantly expanded the Company's wealth management platform through the addition of Pacific Premier's custodial trust business, resulting in a 200% increase in financial services and trust revenue compared to the prior-year period.

<u>[**Table of Contents**](#i2afd483bd7254a5f9ef1108885030a3f_430)</u>

Residential mortgage banking revenue increased during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. The increase was primarily driven by the gain on the fair value of the MSR asset due to valuation inputs and assumptions of $6.0 million during the three months ended March 31, 2026, as compared to a loss of $1.0 million in prior-year period. These increases were partially offset by a MSR hedge loss of $2.0 million, as compared to a gain of $3.0 million, for the same period in the prior year. Changes in the fair value of the MSR asset were recorded in non-interest income in both periods.

Gain (loss) on certain loans held for investment, at fair value, resulted in a loss of $2 million for the three months ended March 31, 2026, compared to a gain of $7 million for the three months ended March 31, 2025. The variance was primarily driven by changes in interest rates between periods.

Other income increased during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025, primarily due to favorable changes in swap related income, a reduction in swap derivative loss, higher miscellaneous income, and increased loan related fees, resulting in a net increase of $7 million between periods.

**Non-Interest Expense** 

The following table presents the key elements of non-interest expense and the related dollar and percentage change from period to period:

---

*Comparison of current quarter to prior quarter*

Salaries and employee benefits decreased during the three months ended March 31, 2026, as compared to the three months ended December 31, 2025, primarily reflecting cost savings associated with the acquisition of Pacific Premier as well as elevated severance costs incurred in the fourth quarter of 2025 that were not repeated in the current quarter.

FDIC assessments increased during the three months ended March 31, 2026, as compared to the three months ended December 31, 2025. The increase was primarily driven by the notification of reduction of $5 million for a FDIC special assessment recorded during the three months ended December 31, 2025, that was not repeated in the current period.

Merger and restructuring expense decreased during the three months ended March 31, 2026, as compared to the three months ended December 31, 2025, reflecting lower charitable contributions, legal and professional fees, and personnel-related costs.

During the three months ended March 31, 2026, the Company completed the systems conversion and consolidated nine branches related to the acquisition of Pacific Premier. Integration activities are ongoing, and the Company continues to expect to realize all previously disclosed cost synergies, which management anticipates will reduce overall non-interest expense levels by June 30, 2026, with the full impact reflected beginning in the third quarter of 2026.

*Comparison of current year-to-date to prior year period*

Salaries and employee benefits increased during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025, primarily reflecting expenses associated with a larger employee base following the acquisition of Pacific Premier.

Occupancy and equipment, net increased during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025, primarily due to an expanded branch footprint and higher software costs resulting from the acquisition of Pacific Premier.

Deposit costs increased during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025, primarily driven by higher HOA-related fees following the expansion of the Company's HOA banking business as part of the acquisition of Pacific Premier.

Intangible amortization increased during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025, reflecting amortization of the core deposit intangibles recognized in connection with the acquisition of Pacific Premier. Refer to Note 6 – *Goodwill and Other Intangible Assets* for additional information regarding expected amortization expense.

Merger and restructuring expense increased during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025, primarily due to costs associated with the acquisition of Pacific Premier. These costs included severance and retention payments, professional service fees, systems conversion and integration activities, contract termination costs, facility consolidation, and other one-time charges necessary to combine operations and align the merged organization.

Legal settlement decreased during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025, reflecting a $55 million accrual recorded in the first quarter of 2025 related to a legal settlement, which was not repeated in the current period.

Columbia operates with a cost-conscious culture, as our associates seek expense offsets to continued investment in customer-focused technology, experienced bankers, and targeted locations. Management expects these strategic investments to create operational efficiency and bring additional revenue opportunities to the Bank in support of our Business Bank of Choice strategy.

 **Income Taxes** 

The Company's effective tax rate for the three months ended March 31, 2026 was 24.7%, as compared to 30.1% for the three months ended March 31, 2025. The effective tax rates differed from the statutory federal income tax rate primarily due to the impact of state income taxes, non-deductible compensation, non-deductible FDIC assessments, and income from tax-exempt investment securities and loans. The change in the effective tax rate for the three months ended March 31, 2026, as compared to the corresponding period in the prior year, was primarily attributable to reduced non-deductible compensation, as the prior year included elevated severance that did not repeat.

**<u>FINANCIAL CONDITION</u>**

**Cash and Cash Equivalents**

Cash and cash equivalents were $2.1 billion as of March 31, 2026 compared to $2.4 billion as of December 31, 2025. The decrease in interest-bearing cash was due to a decision to decrease on balance sheet liquidity as a result of lower liquidity risk as compared to the prior year. The Company manages its cash position within the broader liquidity framework designed to maintain a high-quality liquid asset base, support balance sheet flexibility, fund growth across lending and investment activities, and reduce debt and other non-deposit liabilities when market conditions are favorable.

**Debt Securities** 

Investment debt securities classified as available for sale were $10.9 billion as of March 31, 2026, compared to $11.1 billion as of December 31, 2025. The decrease was primarily due to paydowns, maturities, and calls of $352 million and an $83 million decline in the fair value of available for sale investment securities, reflecting higher interest rates during the period. These decreases were partially offset by $208 million investment securities purchases.

The following tables present the par value, amortized cost, and fair values of investment debt securities as available for sale and held to maturity by major type as of the dates presented:

We evaluate our investment securities on an ongoing basis for potential impairment. This review considers current market conditions, fair value in relationship to cost, the magnitude and duration of unrealized losses, changes in issuer credit ratings or credit trends, and other relevant factors. We also assess whether we intend to sell a security or if it is more likely than not that we will be required to sell the security before recovery of our amortized cost basis, which may be maturity.

As of March 31, 2026, the available for sale investment portfolio had gross unrealized losses of $410 million, including $350 million of unrealized losses on mortgage-backed securities and collateralized mortgage obligations. The unrealized losses were primarily attributable to changes in market interest rates or the widening of market spreads subsequent to the initial purchase of these securities, not deterioration in credit quality. In the opinion of management, no ACL was considered necessary on these debt securities as of March 31, 2026.

**Loans and Leases**

Total loans and leases outstanding as of March 31, 2026 were $47.7 billion, a decrease of $79 million as compared to December 31, 2025. The decrease in loans and leases reflects continued run-off in below-market-rate transactional loans, partially offset by growth in commercial loans. Management expects the remix of our loan portfolio toward relationship-centric lending to continue in future periods, consistent with the Company's balance sheet optimization strategy. The loan-to-deposit ratio was 89% and 88% as of March 31, 2026 and December 31, 2025, respectively.

The following table presents the concentration distribution of the loan and lease portfolio as of the dates presented:

***Loan Origination/Risk Management***

The Bank has certain lending policies and procedures in place that are designed to maximize loan income within an acceptable level of risk. Management reviews and approves these policies and procedures on a regular basis. A reporting system supplements the review process by providing management with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies, and non-performing and potential problem loans. Diversification in the loan portfolio is a means of managing risk associated with fluctuations in economic conditions.

The Bank maintains an independent loan review department that reviews and validates the credit risk program on a periodic basis. Results of these reviews are presented to management and the appropriate committees of our Board of Directors. The loan review process evaluates that the risk identification and assessment decisions made by lenders and credit personnel are in line with our policies and procedures.

For a more comprehensive discussion of our loan and lease underwriting criteria, refer to discussion in the "Loans and Leases" section of Management's Discussion and Analysis included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

***Commercial Real Estate and Commercial Loans***

CRE and commercial loan portfolios are the largest classifications within earning assets, representing 46% and 20%, respectively, of average earning assets at March 31, 2026 and 43% and 20%, respectively, at December 31, 2025. Delinquency and non-accrual loan movements during the period reflect an anticipated move toward a normalized credit environment following a phase of exceptionally high credit quality. Non-performing loans in the CRE and commercial portfolios include $43 million in government guarantees, which offsets our credit exposure in those portfolios.

<u>[**Table of Contents**](#i2afd483bd7254a5f9ef1108885030a3f_430)</u>

*Commercial Real Estate Loans*

The CRE portfolio includes loans to developers and institutional sponsors supporting income-producing or for-sale CRE properties. We mitigate our risk on these loans by requiring collateral values that exceed the loan amount and underwriting the loan with projected cash flow in excess of the debt service requirement. In addition, management tracks the level of owner-occupied CRE loans versus non-owner occupied loans. Owner-occupied real estate loans are based on cash flows from ongoing operations, and the borrower must generally occupy more than 50% of rentable space or pay more than 50% of rents. As of March 31, 2026, approximately 26% of the outstanding principal balance of our CRE loan portfolio were secured by owner-occupied properties.

As of March 31, 2026, the CRE loan portfolio was $27.6 billion, a decrease of $283 million compared to December 31, 2025, driven in part by a $167 million intentional reduction in transactional balances, consistent with the Company's balance sheet optimization strategy. CRE concentrations are managed with a goal of optimizing relationship-driven commercial loans, as well as geographic and business diversity, primarily in our footprint.

Loans secured by multifamily properties, including construction, represented 24% of the total loan portfolio as of both March 31, 2026 and December 31, 2025. These assets continue to perform well due to demand for rental properties in our geographic footprint. Although management believes such concentrations have no more than the normal risk of collectability, a substantial decline in the economy in general, material increases in interest rates, changes in tax and rent control policies, tightening credit or refinancing markets, or a decline in real estate values in the Bank's primary geographic footprint in particular, could have an adverse impact on the repayment of these loans.

*Commercial Loans and Leases*

Commercial loans are made to commercial customers for use in normal business operations to finance working capital needs, equipment purchases, or other projects. The Bank focuses on borrowers doing business within our geographic markets. Commercial loans are generally underwritten individually and secured with the assets of the company and/or the personal guarantee of the business owners. Lease and equipment financing products are designed to address the diverse financing needs of small to large companies, primarily for the acquisition of equipment. As of March 31, 2026, commercial loans held in our loan portfolio were $12.3 billion, an increase of $355 million compared to December 31, 2025, driven primarily by relationship-based loan originations.

The leases and equipment finance portfolio represented approximately 13% of the commercial portfolio and 3% of the total loan portfolio as of both March 31, 2026 and December 31, 2025. Net charge-offs in the FinPac lease portfolio were $14 million for both the three months ended March 31, 2026 and December 31, 2025. Net charge-offs were up $15 million in the remaining commercial portfolio from the prior quarter, driven by an agricultural industry relationship.

<sup>(1)</sup> Commercial non-accrual loans and leases are inclusive of government guarantees of $19 million and $17 million as of March 31, 2026 and December 31, 2025, respectively.

***Residential Real Estate Loans***

Residential real estate loans represent mortgage loans and lines of credit to consumers for the purchase or refinance of a residence. As of March 31, 2026, residential real estate loans held in our loan portfolio were $7.6 billion, a decrease of $143 million as compared to December 31, 2025. Residential real estate loan balances declined during the quarter, primarily reflecting continued runoff driven by prior-period actions to scale the residential lending platform and which have resulted in origination levels that are intentionally below those necessary to fully offset normal loan repayments and paydowns. The decline also reflects the intentional reduction of exposure within the transactional residential mortgage portfolio, consistent with the Company's balance sheet optimization strategy.

***Consumer Loans***

Consumer loans, including secured and unsecured personal loans, personal lines of credit, and motor vehicle loans, decreased $8 million to $170 million as of March 31, 2026, as compared to December 31, 2025. The change was due to normal business activity.

**Asset Quality and Non-Performing Assets** 

The Bank manages asset quality and controls credit risk primarily through diversification of its loan and lease portfolio and the consistent application of credit policies designed to support sound underwriting and loan and lease monitoring practices. The Bank's Credit Quality Administration department is charged with monitoring asset quality, establishing credit policies and procedures, and enforcing the consistent application of these policies and procedures across the Bank. The Bank conducts ongoing reviews of non-performing, past due loans and leases, and larger credits, designed to identify potential charges to the ACL, and to determine the adequacy of the ACL. These reviews consider such factors as the financial strength of borrowers, the value of the applicable collateral, loan and lease loss experience, estimated loan and lease losses, growth in the loan and lease portfolio, prevailing economic conditions, and other factors.

The following table summarizes the Bank's non-performing assets, the ACL, and asset quality ratios as of the dates presented:

| ACL to total non-performing loans and leases | 183% | 245% |

---

<sup>(1)</sup> Non-accrual and 90+ days past due loans include government guarantees of $40 million and $48 million, respectively, as of March 31, 2026. As of December 31, 2025, non-accrual and 90+ days past due loans include government guarantees of $38 million and $41 million, respectively.

<sup>(2)</sup> Excludes certain mortgage loans guaranteed by GNMA for which the Company has a unilateral right to repurchase but has not exercised that right. Such loans totaled $4 million as of March 31, 2026 and $3 million at December 31, 2025.

As of March 31, 2026, loans modified for borrowers experiencing financial difficulties totaled $108 million or 0.23% of total loans, compared to $193 million or 0.40% as of December 31, 2025. A decline in economic conditions and other factors could adversely impact individual borrowers or the loan portfolio as a whole. Accordingly, there can be no assurance that additional loans will not become 90 days or more past due, be placed on non-accrual status, be restructured, or be transferred to other real estate owned in the future. The increase in non-performing loans as of March 31, 2026 is indicative of a more normalized credit environment.

**ALLOWANCE FOR CREDIT LOSSES**

The ACL represents management's best estimate of lifetime credit losses for loans and leases and unfunded commitments. The ACL totaled $478 million as of March 31, 2026, a decrease of $7 million from $485 million as of December 31, 2025. The change in the ACL estimate during the three months ended March 31, 2026 reflects updated economic forecasts incorporated into the Company's credit loss models, as well as portfolio activity during the period.

To calculate the ACL, the CECL models use a forecast of future economic conditions and are dependent upon specific macroeconomic variables that are relevant to each of the Bank's loan and lease portfolios, as well as qualitative factors to address uncertainty not measured within the quantitative analysis. In estimating the March 31, 2026 ACL, the Bank used Moody's Analytics' February 2026 consensus economic forecast to project the variables used in the models and applied upward qualitative overlays across all portfolios to align with the S2 scenario. The 2026 consensus forecast reflects mixed macroeconomic changes, including marginal improvement in projected GDP growth with rising expected unemployment rates, relative to the December 31, 2025 ACL calculation. Refer to Note 5 – *Allowance for Credit Losses* for further information. Refer to Note 1 – *Summary of Significant Accounting Policies* included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025 for a description of the ACL methodology.

The models for calculating the ACL are sensitive to changes to economic variables, which could result in volatility as these assumptions change over time. We believe that the ACL as of March 31, 2026 is sufficient to absorb losses inherent in the loan and lease portfolio and in credit commitments outstanding as of that date based on the information available. If the economic conditions decline, the Bank may need additional provisions for credit losses in future periods.

Residential MSR are adjusted to fair value each quarter, with change in fair value recorded in residential mortgage banking revenue in the Consolidated Statements of Income. MSR assets are recorded in other assets on the Consolidated Balance Sheets. The fair value of servicing rights can fluctuate based on changes in interest rates and other market factors. Generally, declining interest rates increase borrower refinancing activity and prepayment speeds, which reduce the expected life of servicing assets and lowers their fair value as anticipated future servicing fee collections decline. Conversely, increases in market interest rates generally result in lower prepayment expectations and an increase in the fair value of residential MSR.

**Goodwill and Other Intangible Assets**

Goodwill was $1.5 billion as of March 31, 2026 and December 31, 2025. Goodwill is recorded in connection with business combinations and represents the excess of the purchase price over the estimated fair value of the net assets acquired.

As of March 31, 2026, we had other intangible assets of $671 million, as compared to $712 million at December 31, 2025. As part of a business acquisition, the fair value of identifiable intangible assets such as core deposits, which includes all deposits except certificates of deposit, was recognized at the acquisition date. Intangible assets with definite useful lives are amortized to their estimated residual values over their respective estimated useful lives. Core deposit intangibles are amortized on an accelerated basis over a period of 10 years using the sum-of-the-years-digits method. Refer to Note 6 – *Goodwill and Other Intangible Assets*, for forecasted amortization expense for intangible assets as of March 31, 2026. Intangible assets are evaluated for impairment if events and circumstances indicate a possible impairment. No impairment losses have been recognized in the periods presented.

**Deposits** 

Total deposits were $53.5 billion as of March 31, 2026, a decrease of $722 million as compared to December 31, 2025. The decrease was primarily due to an intentional reduction in brokered deposits, partially offset by a modest increase in customer deposit balances.

The following table presents total deposit balances by the categories shown as of the dates presented:

---

| | | | | |
|:---|:---|:---|:---|:---|

The Company's total core deposits, defined as total deposits excluding time deposits greater than $250,000 and all brokered deposits, totaled $50.2 billion as of both March 31, 2026 and December 31, 2025. The Company's total brokered deposits were $1.6 billion or 3% of total deposits as of March 31, 2026, compared to $2.4 billion or 4% of total deposits as of December 31, 2025. Excess cash and funds from customer deposit growth were used to reduce brokered deposits during the three months ended March 31, 2026. Management's funding strategy emphasizes a higher proportion of customer deposits and a reduced reliance on wholesale funding sources, including brokered deposits and FHLB advances. Consistent with this strategy, the Company replaced $200 million of brokered deposits with advances from the FHLB, which provided a more favorable effective cost of funds after considering the associated dividend, as detailed in the following section.

**Borrowings** 

As of March 31, 2026, the Bank had outstanding securities sold under agreements to repurchase of $162 million, a decrease of $45 million from December 31, 2025. The Bank also had outstanding borrowings consisting of advances from the FHLB of $3.4 billion as of March 31, 2026 and $3.2 billion as of December 31, 2025. The increase was primarily attributable to general liquidity management. FHLB advances have fixed interest rates ranging from 3.84% to 3.87% and all mature in 2026. Advances from the FHLB are secured by loans collateralized by real estate.

**Junior and Other Subordinated Debentures** 

The Company had junior and other subordinated debentures with carrying values of $430 million and $435 million as of March 31, 2026 and December 31, 2025, respectively. The change in fair value was driven by higher market interest rates and wider credit spreads, partially offset by higher expected future cash flows. As of March 31, 2026, substantially all of the Company's junior subordinated debentures had interest at variable rates that reset on a quarterly basis based on a spread over three-month term SOFR.

**Liquidity and Cash Flow** 

The principal objective of the Bank's liquidity management program is to ensure liquidity to meet the day-to-day cash flow needs of customers, including deposit withdrawals and draws on credit facilities. The Bank's liquidity strategy includes maintaining sufficient on-balance sheet liquidity to support balance sheet flexibility, fund growth in the loan and investment portfolios, and reduce reliance on non-deposit funding sources as economic conditions permit. Management believes that the Company maintains sufficient cash balances and access to borrowings to operate effectively in the current economic environment and to meet its working capital and other liquidity needs. The Company will continue to prudently manage and evaluate its liquidity positions, including its capacity to fund future loan growth and manage borrowings.

The Bank regularly conducts liquidity stress testing to assess its ability to withstand adverse market conditions and unexpected funding needs. These stress tests consider a range of scenarios, including rapid deposit outflows, changes in collateral requirements for public deposits, and limited access to wholesale funding markets. The results of these analyses inform contingency funding plans and help ensure that sufficient liquidity is maintained under both normal and stressed conditions. The Bank maintains a liquidity buffer and identified contingent sources that are designed to support obligations independent of bank dividends under adverse scenarios. Management believes that the Company's diversified funding sources and available liquidity position provide resilience against potential market disruptions.

The Bank actively monitors its sources and uses of funds on a daily basis to maintain an appropriate liquidity position. Public deposits represent one source of funding, and individual state laws generally require banks to collateralize public deposits in excess of FDIC insurance coverage. Public deposits represented 5% of total deposits as of both March 31, 2026 and December 31, 2025. Collateral requirements vary by state and in certain cases, by institution based on regulatory assessments. Changes in collateral requirements for uninsured public deposits may require the pledging of additional collateral, the use of other funding sources to support collateral needs, or could lead to the withdrawal of certain public deposits.

<u>[**Table of Contents**](#i2afd483bd7254a5f9ef1108885030a3f_430)</u>

The Bank's diversified deposit base provides a significant source of stable, low-cost funding, and reduces reliance on wholesale funding markets. Total core deposits were $50.2 billion as of both March 31, 2026 and December 31, 2025. In addition, the Bank maintains liquidity supported by excess bond collateral of $4.8 billion, further strengthening its liquidity position. In addition to liquidity from core deposits and the repayments and maturities of loans and investment securities, the Bank has the ability to generate liquidity through securities sold under agreements to repurchase, the issuance of brokered certificates of deposit, and the utilization of off-balance sheet funding sources.

The Bank also maintains substantial liquidity through off-balance sheet funding sources. These sources include borrowing capacity under uncommitted lines of credit, advances from the FHLB, and access to the Federal Reserve Bank's Discount Window. Availability under the uncommitted lines of credit is subject to federal funds balances and continued counterparty eligibility, and such facilities are generally intended to support short-term liquidity needs and may limit consecutive day usage.

The following table presents total off-balance sheet liquidity as of the date presented:

The Company is a separate legal entity from the Bank and is required to maintain its own liquidity. Substantially all of the Company's cash flows are derived from dividends declared and paid by the Bank. During the three months ended March 31, 2026, there were $125 million of dividends paid by the Bank to the Company. There are statutory and regulatory provisions that limit the ability of the Bank to pay dividends to the Company. FDIC and Oregon Division of Financial Regulation approval is required for quarterly dividends from the Bank to the Company. In addition to dividends, the Company may utilize other capital management actions to support parent-level liquidity and capital objectives, as appropriate.

Looking ahead, management expects the liquidity positions of both the Bank and the Company to remain satisfactory through 2026, with possible fluctuations in deposit balances due to pricing pressure or customers' behavior in the current economic environment. To support liquidity, the Bank may adjust deposit pricing, which could increase interest expense, or utilize more costly borrowings and other funding sources. Management will continue to closely monitor liquidity levels, conduct regular stress testing, and maintain contingency plans to address potential risks, including regulatory changes and market volatility.

*Commitments and Other Contractual Obligations -* The Company participates in many different contractual arrangements which may or may not be recorded on its balance sheet, under which the Company has an obligation to pay certain amounts, provide credit or liquidity enhancements, or provide market risk support. Our material contractual obligations are primarily for time deposits and borrowings. As of March 31, 2026, time deposits totaled $5.7 billion, of which $5.6 billion mature in a year or less. Total FHLB advances as of March 31, 2026 were $3.4 billion, all of which mature within one year. These arrangements also include off-balance sheet commitments to extend credit, letters of credit, and various forms of guarantees. As of March 31, 2026, our loan commitments were $11.9 billion, and letter of credit commitments were $429 million. A portion of the commitments will eventually result in funded loans and increase our profitability through net interest income when drawn and unused commitment fees prior to being drawn. Refer to Note 8 – *Commitments and Contingencies* for further information. Financing commitments, letters of credit, and deferred purchase commitments are presented at contractual amounts and do not necessarily reflect future cash outflows as many are expected to expire unused or partially used.

**Capital Resources** 

Shareholders' equity as of March 31, 2026 was $7.7 billion, a decrease of $176 million from December 31, 2025. The decrease in shareholders' equity during the three months ended March 31, 2026 was principally due to stock purchased and retired of $215 million, cash dividends paid of $107 million, and other comprehensive loss of $58 million, partially offset by net income of $192 million.

The Company's dividend policy considers a number of factors, including earnings, regulatory capital requirements, the overall payout ratio, and expected asset growth, in determining the amount of dividends, if any, to be declared on a quarterly basis. There can be no assurance that future cash dividends on common shares will be declared or increased. Management cannot predict the impact of changes in economic conditions that could result in reduced or insufficient earnings, regulatory restrictions or limitations, changes to capital requirements, or a determination to retain earnings to strengthen capital, any of which could limit or eliminate the Company's ability to pay dividends at historical levels, or at all.

On February 13, 2026, the Company declared a cash dividend of $0.37 per common share related to fourth quarter 2025 performance, which was paid on March 16, 2026.

The following table presents cash dividends declared and the related dividend payout ratios (dividends declared per common share divided by basic earnings per common share) for the periods presented:

As of March 31, 2026, the Company has authorization from its Board to repurchase up to $700 million of shares of common stock. Authorization for such share repurchase program will expire on November 30, 2026. As of March 31, 2026, $400 million remained available to repurchase shares under this program. During the three months ended March 31, 2026, the Company repurchased 6.5 million shares under this plan. The timing and amount of future repurchases will depend upon the market price for our common stock, securities laws restricting repurchases, asset growth, earnings, our capital plan, and bank or bank holding company regulatory approvals.

As part of the Company's capital management strategy, and in support of Columbia's authorized share repurchase program, the Bank upstreams capital through the repurchase of Bank common stock rather than through dividends. This approach allows capital to be transferred to the parent while avoiding reductions to Bank retained earnings. During the three months ended March 31, 2026, the Bank repurchased $200 million of its common stock. These transactions are accounted for as reductions to Bank common stock, represent intercompany equity transactions, and do not impact consolidated capital, results of operations, or regulatory capital ratios. Bank stock repurchases are distinct from dividends and are executed subject to applicable state and federal regulatory approvals.

The Company is committed to managing capital to maintain strong protection for depositors and creditors and for maximum shareholder benefit. The Company also manages its capital to exceed regulatory capital requirements for banking organizations. Regulatory capital requirements applicable to the Company are based on Basel III and require the Company to calculate capital adequacy as a percentage of risk-weighted assets under the standardized approach. All regulatory ratios exceeded regulatory "well-capitalized" requirements.

An interest rate simulation model is used to estimate the sensitivity of net interest income to changes in market interest rates. The simulation model does not take into account any future actions management could undertake to mitigate the impact of interest rate changes or the impact a change in interest rates may have on our credit risk profile, loan prepayment estimates, and spread relationships, which can change regularly. Actions we could undertake include, but are not limited to, growing or contracting the balance sheet, changing the composition of the balance sheet, or changing our pricing strategies for loans or deposits.

Simulation results indicate limited exposure to interest rate risk in an increasing rate environment, with increasing net interest income in a declining interest rate environment.

The short-term interest rate environment is primarily a function of the monetary policy of the Federal Reserve Board. The federal funds rate, the basis for overnight funding and driver of the short end of the yield curve, remained at 3.75% during the first quarter of 2026. Longer maturities are influenced by the market's expectations for economic growth and inflation but can also be influenced by Federal Reserve purchases and sales and expectations of monetary policy going forward.

Based on the FOMC Members' median expectations for the federal funds target rate, the federal funds rate is projected to remain stable at 3.75% for the remainder of 2026.

***Economic Value of Equity***

Another interest rate sensitivity measure we utilize is the quantification of economic value changes for all financial assets and liabilities, given an increase or decrease in market interest rates. This approach provides a longer-term view of interest rate risk, capturing all future expected cash flows.

The table below illustrates the effects of various instantaneous rate changes on the fair values of financial assets and liabilities compared to the corresponding carrying values and fair values as of the dates presented:

---

| | | |
|:---|:---|:---|
| | **March 31, 2026** | **December 31, 2025** |
| Up 300 basis points | (6.9)% | (10.1)% |
| Up 200 basis points | (4.4)% | (6.5)% |
| Up 100 basis points | (2.2)% | (3.3)% |
| Down 100 basis points | 2.1% | 3.2% |
| Down 200 basis points | 3.4% | 5.3% |
| Down 300 basis points | 1.9% | 4.6% |

Our EVE analysis indicates a liability sensitive profile in increasing interest rate scenarios. This suggests a sudden or sustained increase in market interest rates would result in a decrease in our estimated EVE, as the decrease in the economic value of our interest-earning assets exceeds the economic value change of interest-bearing liabilities. In declining interest rate scenarios, our EVE increases. This occurs as the increase in the economic value of interest-earning assets exceeds the decline in economic value of interest-bearing liabilities, including core deposit intangibles. As of March 31, 2026, our estimated EVE (fair value of financial assets and liabilities) was above our book value of equity primarily due to the economic value of the core deposit intangibles.

**Item 4.&nbsp;&nbsp;&nbsp;&nbsp;Controls and Procedures** 

Our management, including our Chief Executive Officer, Chief Financial Officer and Principal Accounting Officer, has concluded that our disclosure controls and procedures are effective in timely alerting them to information relating to us that is required to be included in our periodic filings with the SEC. The disclosure controls and procedures were last evaluated by management as of March 31, 2026.

No change in internal control over financial reporting occurred during the quarter ended March 31, 2026 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.
