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 $147.9 million and $148.0 million as of June 30, 2025 and December 31, 2024, respectively, and is included in other assets on the Condensed Consolidated Balance Sheets. As of June 30, 2025, loans totaling $22.4 billion were pledged to secure borrowings and available lines of credit, compared to $22.0 billion as of December 31, 2024.

As of June 30, 2025 and December 31, 2024, the net deferred fees and costs were $60.4 million and $62.0 million, respectively. Total loans and leases also include discounts on acquired loans of $388.7 million and $439.0 million as of June 30, 2025 and December 31, 2024, 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. 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 $153.4 million and $199.9 million as of June 30, 2025 and December 31, 2024, respectively. The carrying balance of PCD loans was $136.2 million and $178.5 million as of June 30, 2025 and December 31, 2024, 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 $5.7 million and $11.4 million for the three and six months ended June 30, 2025, respectively, as compared to $5.5 million and $10.4 million for the six months ended June 30, 2024, respectively.

Allowance for Credit Losses

6 Months Ended

Jun. 30, 2025

Allowance for Credit Losses

The ACL represents management's estimate of lifetime credit losses for assets within its scope, specifically loans and leases and unfunded commitments. For more information about the Company's ACL methodology, 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, 2024.

At June 30, 2025, the ACL was $439.0 million, a decrease of $1.8 million from the December 31, 2024 balance of $440.8 million. The change in the total ACL reflects credit migration trends, changes in the economic assumptions, and a recalibration of the commercial real estate, residential mortgage, and home equity line of credit CECL models in the first quarter of 2025. To calculate the ACL, management uses models to estimate PD and LGD for loans and leases, incorporating forecasted economic conditions and macroeconomic variables. The Bank considers the current financial environment and various economic scenarios, selecting the most probable scenario at each measurement date. Forecasts for each variable are updated and incorporated into the ACL calculation. Projected macroeconomic variables over the forecast period can materially impact the ACL, with projections becoming less certain over time.

The Bank opted to use Moody's Analytics' May 2025 consensus economic forecast for estimating the ACL as of June 30, 2025. 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	1.5	%	2.0	%	2.0	%	2.0	%
U.S. unemployment rate average	4.5	%	4.3	%	4.3	%	4.1	%
Forecasted average federal funds rate	3.3	%	3.4	%	3.4	%	3.4	%

The Bank also uses an additional scenario with varying severity to assess ACL sensitivity and inform qualitative adjustments, keeping economic variables consistent. For this analysis, the Bank selected Moody's Analytics' May 2025 S2 scenario, which predicts a 75% probability of better economic performance and a 25% probability of worse performance. The scenario includes the following variables:


	2026		2027		2028		2029
U.S. real GDP average annualized growth	0.2	%	2.7	%	2.9	%	2.8	%
U.S. unemployment rate average	6.9	%	5.2	%	4.6	%	4.4	%
Forecasted average federal funds rate	2.3	%	2.0	%	2.7	%	2.9	%

The forecast used to calculate the ACL as of June 30, 2025 reflects a deterioration in macroeconomic conditions, including lower projected GDP growth and higher expected unemployment rates, relative to the December 31, 2024 ACL calculation, which was based on Moody’s Analytics’ November 2024 consensus economic forecast. These changes negatively impacted the quantitative portion of the modeled ACL estimate. Management reviewed the results derived from the economic scenarios and the subsequent changes in macroeconomic variables through sensitivity analysis and considered these factors when evaluating qualitative adjustments.

To address the heightened economic uncertainty and sector-specific risks, management applied offsetting qualitative adjustments, primarily focused on the commercial real estate and commercial loan portfolios. These overlays are directionally consistent with those applied as of December 31, 2024 and were deemed necessary to ensure the ACL remains appropriately aligned with the Company’s risk profile. As a result, the overall ACL remained relatively stable despite the less favorable economic outlook.

While qualitative overlays are applied, approximately 83% of the ACL is driven by modeled results, which management believes adequately reflect the significant changes in credit conditions and overall portfolio risk. Management believes the ACL was adequate as of June 30, 2025. However, there can be no assurance that future loan losses will not exceed the levels provided for in the ACL, which could result in additional provisions for credit losses.

The following tables summarize activity related to the ACL by portfolio segment for the periods indicated:

Asset Quality and Non-Performing Loans and Leases

The Bank 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. 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, are conducted on an ongoing basis. 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.

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 June 30, 2025 and December 31, 2024, loans and leases on non-accrual status with no related ACL was $2.8 million and $3.6 million, respectively, excluding collateral dependent loans and leases that have been written down to net realizable value without an associated ACL of $46.6 million and $59.4 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 and six months ended June 30, 2025 and 2024.

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 and six months ended June 30, 2025 and 2024, 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.

The Company closely monitors the performance of loans and leases to borrowers experiencing financial difficulty that are modified to understand the effectiveness of its modification efforts. Loans and leases are considered to be in payment default at 90 or more days past due. For the three months ended June 30, 2025, all modified loans and leases were current and there were no loan or lease modifications made to borrowers experiencing financial difficulty that subsequently defaulted. The following tables present the amortized cost basis of modified loans that, within twelve months of the modification date, experienced a subsequent default during the periods presented:

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 original 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, 2024.

The following tables present the amortized cost basis of the loans and leases by credit classification and vintage year by loan and lease class of financing receivable, as well as gross charge-offs for the dates presented:

Commitments and Contingencies

Financial Instruments with Off-Balance-Sheet Risk — The Company's financial statements do not reflect various commitments and contingent liabilities that arise in the normal course of the Bank's business and involve elements of credit, liquidity, and interest rate risk.

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


(in thousands)	June 30, 2025		December 31, 2024
Commitments to extend credit	$	10,042,369	$	10,077,780
Forward sales commitments	$	71,500	$	76,535
Commitments to originate residential mortgage loans held for sale	$	58,919	$	46,208
Standby letters of credit	$	321,187	$	216,422

The Bank is a party to financial instruments with off-balance sheet credit risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve elements of credit and interest-rate risk similar to the risk involved in on-balance sheet items. The contract or notional amounts of these instruments reflect the extent of the Bank's exposure in particular classes of financial instruments.

The Bank's exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit, and financial guarantees written, is represented by the contractual notional amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet 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 involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank holds cash, marketable securities, or real estate as collateral supporting those commitments for which collateral is deemed necessary. There were no financial guarantees in connection with standby letters of credit that the Bank was required to perform on during the three and six months ended June 30, 2025 and 2024. As of June 30, 2025, approximately $295.2 million of standby letters of credit expire within one year, and $26.0 million expire thereafter.

Residential mortgage loans sold into the secondary market are sold with limited recourse against the Company, meaning that the Company may be obligated to repurchase or otherwise reimburse the investor for incurred losses on any loans that suffer an early payment default, are not underwritten in accordance with investor guidelines or are determined to have pre-closing borrower misrepresentations.

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.

In September 2023, 34 related entities (the “iCap Entities”) that maintained their primary deposit accounts with the Bank filed jointly-administered Chapter 11 bankruptcies in the United States Bankruptcy Court for the Eastern District of Washington. The Bank was served with a request for production of account records and produced such records through counsel. Concurrently, in pleadings filed in the Bankruptcy Court for the Eastern District of Washington on behalf of investors who claimed losses of approximately $290.0 million, the Bank was identified as a party against which claims may be brought in connection with the iCap Entities’ alleged operation of Ponzi schemes prior to the bankruptcy proceedings described above. The potential claims against the Bank and the amount of any alleged damages are not estimable. To the extent suits or actions are commenced, the Bank intends to vigorously defend against any and all claims.

In August 2020, a class action complaint was filed in the United States District Court for the Northern District of California alleging aiding and abetting claims against the Bank associated with the failure of two commercial real estate investment companies, Professional Financial Investors, Inc. and Professional Investors Security Fund, Inc., allegedly effected through a Ponzi scheme. Both companies maintained their primary deposit account relationship with the Bank’s Novato, Marin County, California branch office, acquired by the Bank from Circle Bank. The Bank's motion to dismiss was denied in January 2021, and its motion for summary judgment was denied in December 2022, and at the same time the District Court certified the plaintiffs’ proposed class. Two other related cases were filed in 2023: one case alleges similar claims by two investors and was filed in May 2023 in Marin County Superior Court; and another case was filed in June 2023 in the United States District Court for the Northern District of California alleging claims by ten investors with different investments than the class members. Filing of these cases follows an SEC non-public investigation of Professional Financial Investors, Inc. and Professional Investors Security Fund, Inc. that commenced on May 28, 2020. The District Court case filed in June 2023 was dismissed in July 2024 due to the plaintiffs' lack of standing. The Superior Court case does not yet have a clear estimate of damages and the Bank intends to defend this matter vigorously as appropriate and believes it has meritorious defenses. Plaintiffs in the District Court class action case alleged damages resulting from the scheme of between $297.4 million and $368.1 million, including prejudgment interest. Trial in the District Court class action case commenced on February 3, 2025 and a mistrial was declared on March 4, 2025. The Bank subsequently engaged in a court ordered settlement conference, and a Notice of Settlement was filed on March 27, 2025, which contemplates a settlement payment of $55.0 million by the Bank, including any attorneys' fees or costs. The settlement is subject to final court approval, with the hearing for final court approval scheduled for September 11, 2025. If approved, the settlement is expected to be funded in late 2025.

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 filesharing 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").

Other than the information described above, no account information for accounts at the Bank was compromised as a result of the Vendor Incident, and no information from the Bank’s commercial customers was involved in the Vendor Incident. On June 22, 2023, the Bank sent an email to potentially affected consumer and small business customers informing them of the Vendor Incident. Between August 11, 2023, and August 15, 2023, the Vendor, on behalf of the Bank, initiated formal notice via U.S. Mail to the 429,252 Bank customers whose information was involved in the Vendor Incident. The Bank and the Vendor also notified applicable federal and state regulators regarding the Vendor Incident.

Beginning on August 18, 2023, some of the individuals who were notified of the Vendor Incident filed lawsuits against the Bank seeking monetary recovery and other relief on behalf of themselves and one or more putative classes of other individuals similarly situated. Two such cases were filed in federal court (the United States District Court for the Western District of Washington), one of which was later voluntarily dismissed without prejudice. Five such cases were filed in state court in Washington (the Washington Superior Court for Pierce County) and one case in state court in California (the California Superior Court for Contra Costa County). The state court cases were subsequently removed to federal court by the Bank. On October 4, 2023, the United States Judicial Panel on Multidistrict Litigation, in view of the large number of lawsuits arising out of the MOVEit data incident in federal courts across the United States, initiated a multidistrict litigation (“MDL”) for these cases to allow such cases to be transferred to one court for pre-trial proceedings. The MDL is titled In Re: MOVEit Customer Data Security Breach Litigation, MDL No. 3083 and is pending in the United States District Court for the District of Massachusetts as MDL No. 1:23-md-03083-ADB-PGL. All seven cases against the Bank have been transferred to the MDL as of January 29, 2024. The cases 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 statutes, namely the Washington Consumer Protection Act, the California Consumer Legal Remedies Act, the California Consumer Privacy Act, and the California Unfair Competition Law. The Bank has also received claims by or on behalf of individuals in connection with the Vendor Incident. Such claims have the potential to give rise to additional litigation. The Bank has engaged defense counsel and intends to vigorously defend against these suits and any similar or related suits 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. In addition to the settlement payment accrual noted above, the Company has $1.2 million accrued related to other legal matters as of June 30, 2025, which is recorded as a component of other liabilities on the Condensed Consolidated Balance Sheets.

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.

Contingencies— The Merger Agreement between Columbia and Pacific Premier contains certain termination rights for both Columbia and Pacific Premier providing that upon termination of the Merger Agreement under certain circumstances, Columbia or Pacific Premier, as applicable, will be obligated to pay the other party a termination fee of $75.0 million.

Concentrations of Credit Risk—The Bank grants real estate mortgage, real estate construction, commercial, agricultural and installment loans and leases to customers in Oregon, Washington, California, Idaho, Nevada, Arizona, Colorado, and Utah. In management's judgment, a concentration exists in real estate-related loans, which represented approximately 75% of the Bank's loan and lease portfolio for both June 30, 2025 and December 31, 2024. CRE concentrations are managed to ensure geographic and business diversity, primarily in our footprint. The multifamily portfolio, including construction, represented approximately 19% of the total loan portfolio as of both June 30, 2025 and December 31, 2024. The office portfolio represented approximately 8% of the total loan portfolio as of both June 30, 2025 and December 31, 2024. 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 policies, tightening credit or refinancing markets, or a decline in real estate values in the Bank's primary market areas in particular, could have an adverse impact on the repayment of these loans. Personal and business incomes, proceeds from the sale of real property, or proceeds from refinancing represent the primary sources of repayment for a majority of these loans.

The Bank recognizes the credit risks inherent in dealing with other depository institutions. Accordingly, to prevent excessive exposure to any single correspondent, the Bank has established general standards for selecting correspondent banks as well as internal limits for allowable exposure to any single correspondent. In addition, the Bank has an investment policy that sets forth limitations that apply to all investments with respect to credit rating and concentrations with an issuer.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

The Bank may use derivatives to hedge the risk of changes in the fair values of interest rate lock commitments, residential mortgage loans held for sale, and MSRs. None of the Company's derivatives are designated as hedging instruments. Rather, they are accounted for as free-standing derivatives, or economic hedges, with changes in the fair value of the derivatives reported in income. The Company utilizes forward interest rate contracts in its derivative risk management strategy.

The Bank enters into forward delivery contracts to sell residential mortgage loans or mortgage-backed securities to broker-dealers at specific prices and dates in order to hedge the interest rate risk in its portfolio of mortgage loans held for sale and its residential mortgage interest rate lock commitments. Credit risk associated with forward delivery contracts is limited to the replacement cost of those forward delivery contracts in a gain position. There were no counterparty default losses on forward delivery contracts in the three and six months ended June 30, 2025 and 2024. Market risk with respect to forward delivery contracts arises principally from changes in the value of contractual positions due to changes in interest rates. The Bank limits its exposure to market risk by monitoring differences between commitments to customers and forward delivery contracts with broker-dealers. In the event the Company has forward delivery contracts commitments in excess of available mortgage loans, the Company completes the transaction by either paying or receiving a fee to or from the broker-dealer equal to the increase or decrease in the market value of the forward delivery contracts. As of June 30, 2025 and December 31, 2024, the Bank had commitments to originate mortgage loans held for sale totaling $58.9 million and $46.2 million, respectively, and forward sales commitments of $71.5 million and $76.5 million, respectively.

The Bank purchases interest rate futures and forward settling mortgage-backed securities to hedge the interest rate risk of MSRs. As of June 30, 2025, the Bank had $188.0 million notional of interest rate futures contracts and $17.0 million of mortgage-backed securities. As of December 31, 2024, the Bank had $187.0 million notional of interest rate futures contracts and $12.0 million of mortgage-backed securities related to this program.

The Bank executes interest rate swaps with commercial banking borrowers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting the interest rate swaps that the Bank executes with a third party, such that the Bank minimizes its net risk exposure. As of June 30, 2025, the Bank had interest rate swap assets with a notional amount of $4.4 billion and interest rate swap liabilities with a notional amount of $4.4 billion related to this program. As of December 31, 2024, the Bank had interest rate swap assets and interest rate swap liabilities, with notional amounts of $4.3 billion and $4.4 billion, respectively.

The Bank has collateral posting requirements for initial margins with its clearing houses and is required to post collateral against its obligations under these interest rate swaps of $87.9 million and $87.2 million as of June 30, 2025 and December 31, 2024, respectively.

The Bank's clearable interest rate swap derivatives are cleared through the Chicago Mercantile Exchange and London Clearing House. These clearing houses characterize the variation margin payments, for certain interest rate swap derivative contracts that are referred to as settled-to-market, as settlements of the derivative's mark-to-market exposure and not collateral. The Company accounts for the variation margin as an adjustment to cash collateral, as well as a corresponding adjustment to the derivative asset and liability. As of June 30, 2025 and December 31, 2024, the variation margin netting adjustments for centrally cleared interest rate swaps consisted of derivative asset adjustments of $114.2 million and $173.9 million, respectively.

The Bank also has solely executed interest rate swaps indexed to Term SOFR, which are not clearable. These interest rate swaps are executed on a bilateral basis with a counterparty bank. There is no initial margin posted for bilateral swaps, but cash collateral equivalent to variation margin is exchanged to cover the mark-to-market exposure on a daily basis.

The Bank also executes foreign currency hedges as a service for customers. These foreign currency hedges are then offset with hedges with other third-party banks to limit the Bank's risk exposure.

The Bank's derivative assets are included in other assets on the Condensed Consolidated Balance Sheets, while the derivative liabilities are included in other liabilities on the Condensed Consolidated Balance Sheets. The following table summarizes the types of derivatives, separately by assets and liabilities, and the fair values of such derivatives as of the dates presented:

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 $5.8 million and $11.7 million for the three and six months ended June 30, 2025, respectively, as compared to $6.0 million and $12.0 million for the three and six months ended June 30, 2024, respectively.

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— The fair value of the interest rate lock commitments, interest rate futures, and forward sales commitments are estimated using quoted or published market prices for similar instruments, adjusted for factors such as pull-through rate assumptions based on historical information, where appropriate. The pull-through rate assumptions are considered Level 3 valuation inputs and are significant to the interest rate lock commitment valuation; as such, the interest rate lock commitment derivatives are classified as Level 3. The fair value of the interest rate swaps is determined using a DCF technique incorporating credit valuation adjustments to reflect non-performance risk in the measurement of fair value. Although the Bank has determined that the majority of the inputs used to value its interest rate swap derivatives fall within Level 2 of the fair value hierarchy, the CVA associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of June 30, 2025, the Bank has assessed the significance of the impact of the CVA on the overall valuation of its interest rate swap positions and has determined that the CVA are not significant to the overall valuation of its interest rate swap derivatives. As a result, the Bank has classified its interest rate swap and futures derivative valuations in Level 2 of the fair value hierarchy.

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 (in thousands)		Valuation Technique	Unobservable Input	Range of Inputs	Weighted Average
June 30, 2025
Assets:
Residential mortgage servicing rights	$	102,863	Discounted cash flow	Constant prepayment rate	5.77% - 31.60%	7.40%
				Discount rate	9.50% - 16.23%	10.20%
Interest rate lock commitments, net	$	435	Internal pricing model	Pull-through rate	66.95% - 100.00%	86.16%
Liabilities:
Junior subordinated debentures	$	323,015	Discounted cash flow	Credit spread	2.18% - 4.52%	3.40%

Financial Instrument	Fair Value (in thousands)		Valuation Technique	Unobservable Input	Range of Inputs	Weighted Average
December 31, 2024
Assets:
Residential mortgage servicing rights	$	108,358	Discounted cash flow	Constant prepayment rate	5.77% - 60.85%	6.92%
				Discount rate	9.50% - 16.16%	10.23%
Liabilities:
Interest rate lock commitments, net	$	16	Internal pricing model	Pull-through rate	71.00% - 100.00%	87.54%
Junior subordinated debentures	$	330,895	Discounted cash flow	Credit spread	1.46% - 4.15%	3.06%

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.

An increase in the pull-through rate utilized in the fair value measurement of the interest rate lock commitment derivative will result in an increase in the fair value measurement. Conversely, a decrease in the pull-through rate will result in a decrease in the fair value measurement.

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.

The following table provides a reconciliation of assets and liabilities measured at fair value using significant unobservable inputs (Level 3) on a recurring basis for the periods indicated:

Changes in residential mortgage servicing rights carried at fair value are recorded in residential mortgage banking revenue within non-interest income. Gains (losses) on interest rate lock commitments 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 losses of $1.9 million and unrealized gains of $7.7 million for the three and six months ended June 30, 2025 were recorded net of tax as other comprehensive losses of $1.4 million and gains of $5.7 million, respectively. Comparatively, unrealized losses of $384,000 and unrealized gains of $6.1 million were recorded net of tax as other comprehensive losses of $284,000 and gains of $4.5 million for the three and six months ended June 30, 2024, respectively. The change recorded for the three months ended June 30, 2025 was mainly due to changes in swap rates and decreases in credit spreads. The change recorded for the six months ended June 30, 2025 was driven by increases in credit spreads and changes in swap rates.

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.


	June 30, 2025

(in thousands)	Total		Level 1		Level 2		Level 3
Loans and leases	$	22,854	$	—	$	—	$	22,854


	December 31, 2024

(in thousands)	Total		Level 1		Level 2		Level 3



Loans and leases	$	28,177	$	—	$	—	$	28,177

The following table presents the losses resulting from nonrecurring fair value adjustments for the periods indicated:


	Three Months Ended				Six Months Ended
(in thousands)	June 30, 2025		June 30, 2024		June 30, 2025		June 30, 2024

Loans and leases	$	25,857	$	30,704	$	54,539	$	58,878

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:


	June 30, 2025						December 31, 2024
(in thousands)	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	$	52,977	$	51,255	$	1,722	$	71,535	$	70,430	$	1,105
Loans held for investment	$	177,949	$	204,422	$	(26,473)	$	168,809	$	200,925	$	(32,116)

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 Condensed 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 and six months ended June 30, 2025, the Company recorded a net decrease in fair value of $272,000 and net increase in fair value of $617,000, respectively. For the three and six months ended June 30, 2024, the Company recorded a net increase in fair value of $127,000 and $316,000, respectively.

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 Condensed Consolidated Statements of Income. For the three and six months ended June 30, 2025, the Company recorded a net increase in fair value of $212,000 and $7.2 million, respectively, as compared to a net decrease in fair value of $10.1 million and $12.5 million for the three and six months ended June 30, 2024, respectively.

The Company selected the fair value measurement option for certain junior subordinated debentures originally issued by UHC prior to the Umpqua Merger (the Umpqua Statutory Trusts) and for junior subordinated debentures acquired by UHC from Sterling Financial Corporation prior to the Umpqua Merger, 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.

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2025
Income Tax Disclosure [Abstract]
Income Taxes and Investment Tax Credits	Income Taxes and Investment Tax Credits The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, as well as in the majority of 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 June 30, 2025, the Company had a net deferred tax asset of $299.0 million, which includes $1.5 million of federal and state NOL carry-forwards, expiring in tax years 2030-2031. The Company recorded income tax expense of $88.3 million and $85.9 million for the six months ended June 30, 2025 and 2024, respectively, representing effective tax rates of 27.0% and 26.0%, respectively. The effective tax rates differed from the statutory rate principally because of state 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 six months ended June 30, 2025, as compared to the corresponding period in the prior year, was primarily attributable to an increase in non-deductible compensation. On July 4, 2025, the One Big Beautiful Bill Act was signed into law. The Company is evaluating the impact of the new law on its consolidated financial statements but does not believe it will have a material impact. 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 $226.0 million and $221.0 million as of June 30, 2025 and December 31, 2024, respectively, as a component of other assets on the Condensed Consolidated Balance Sheets and uses the proportional amortization method to account for the investments. The Company's unfunded capital commitments to these investments were $94.7 million and $95.3 million as of June 30, 2025 and December 31, 2024, respectively, which are recorded as a component of other liabilities on the Condensed Consolidated Balance Sheets. Amortization related to these investments is recorded as a component of the provision for income taxes on the Condensed Consolidated Statements of Income.

The entire disclosure for income tax.

Segment Reporting	6 Months Ended
Segment Reporting	Jun. 30, 2025
Segment Reporting [Abstract]
Segment Reporting	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 Oregon, Washington, California, Idaho, Nevada, Arizona, Colorado, and Utah 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 Condensed Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2024. The Company's CODM is the Chief Executive Officer. The CODM assesses performance and decides how to allocate resources based on consolidated net income that is reported on the Condensed Consolidated Statements of Income. The measure of segment assets is total consolidated assets which is reported on the Condensed Consolidated Balance Sheets. The CODM uses consolidated net income to evaluate income generated from segment assets in making decisions about the allocation of operating and capital resources. Net income is used to monitor budget versus actual results. The CODM also uses consolidated net income 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 Condensed Consolidated Statements of Income.

Reportable segments include those that meet any of the following quantitative thresholds a) it's reported revenue, including sales to external customers and intersegment sales or transfers is 10 percent or more of the combined revenue, internal and external, of all operating segments b) the absolute amount of its reported profit or loss is 10 percent or more of the greater, in absolute amount of 1) the combined reported profit of all operating segments that did not report a loss or 2) the combined reported loss of all operating segments that did report a loss c) its assets are 10 percent or more of the combined assets of all operating segments.

Accounting Policies [Abstract]

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 (dba: Umpqua Bank) (the "Bank"). In order to align with the name of the holding company and the variety of brands already operated by the Bank today under the Columbia name, the Company renamed the Bank to "Columbia Bank" effective July 1, 2025, and the Bank will begin doing business under the Columbia Bank name and brand beginning on September 1, 2025. FinPac is a commercial equipment leasing company and a wholly-owned subsidiary of the Bank. The accompanying interim condensed 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 condensed 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, 2024. These interim condensed 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, 2024.

In preparing these condensed consolidated financial statements, the Company has evaluated events and transactions subsequent to June 30, 2025, 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 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.

Economic forecast Model Variables

The Bank opted to use Moody's Analytics' May 2025 consensus economic forecast for estimating the ACL as of June 30, 2025. 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	1.5	%	2.0	%	2.0	%	2.0	%
U.S. unemployment rate average	4.5	%	4.3	%	4.3	%	4.1	%
Forecasted average federal funds rate	3.3	%	3.4	%	3.4	%	3.4	%

The Bank also uses an additional scenario with varying severity to assess ACL sensitivity and inform qualitative adjustments, keeping economic variables consistent. For this analysis, the Bank selected Moody's Analytics' May 2025 S2 scenario, which predicts a 75% probability of better economic performance and a 25% probability of worse performance. The scenario includes the following variables:


	2026		2027		2028		2029
U.S. real GDP average annualized growth	0.2	%	2.7	%	2.9	%	2.8	%
U.S. unemployment rate average	6.9	%	5.2	%	4.6	%	4.4	%
