•On August 31, 2025, the Company completed its all-stock acquisition of Pacific Premier, the parent company of Pacific Premier Bank, National Association. Pursuant to the terms of the acquisition agreement, Pacific Premier stockholders received 0.9150 of a share of Columbia common stock for each share of Pacific Premier common stock they held.

Current report

•Net interest margin, on a tax-equivalent basis, was 3.84% for the three months ended September 30, 2025, as compared to 3.75% for the three months ended June 30, 2025, due to one month operating as a combined company and a favorable shift into lower-cost funding sources, which reduced deposit costs. The average cost of interest-bearing deposits declined by 9 basis points to 2.43%, reflecting proactive rate management following the Federal Reserve's September rate cut and a reduction in brokered deposits. Additionally, the amortization of Pacific Premier's time deposit premiums contributed approximately $4 million to net interest income. Overall, the cost of interest-bearing liabilities declined to 2.65%, a 13-basis-point decrease from the prior quarter, as a reduction in the balance of borrowings provided further benefit.

Current report

•Non-interest income was $77 million for the three months ended September 30, 2025, as compared to $65 million for the three months ended June 30, 2025. The increase was driven by one month operating as a combined company and quarterly changes in fair value adjustments and MSR hedging activity, due to interest rate fluctuations during the quarter, resulting in a net fair value gain of $5 million in the third quarter compared to a net fair value loss of $1 million in the prior quarter.

Current report

•Non-interest expense was $393 million for the three months ended September 30, 2025, an increase of $115 million as compared to the three months ended June 30, 2025, primarily due to an increase of $79 million in merger and restructuring expenses compared to the prior quarter and one month operating as a combined company.

Current report

•Earnings per diluted common share was $1.53 for the nine months ended September 30, 2025, as compared to $1.87 for the nine months ended September 30, 2024. The decline reflects higher non-interest expense, including a legal settlement and one-time merger and restructuring expenses, and increased provision expense related to the initial provision for non-PCD loans. These impacts were partially offset by higher net interest income, driven by one month of combined operations following the Pacific Premier acquisition.

Current report

•Net interest margin, on a tax-equivalent basis, was 3.73% for the nine months ended September 30, 2025, as compared to 3.55% for the nine months ended September 30, 2024. The increase reflects lower funding costs and a favorable shift toward lower-cost customer deposits from higher-cost wholesale funding, partially offset by lower earning asset yields from fluctuating interest rates and product repricing between periods. The amortization of Pacific Premier's time deposit premiums contributed approximately $4 million to net interest income during September 2025.

Current report

•Non-interest income was $208 million for the nine months ended September 30, 2025, as compared to $161 million for the nine months ended September 30, 2024. The increase was driven by changes in fair value adjustments and growth in customer-related fee income, as well as one month operating as a combined company. The change in fair value included a net gain of $14 million related to loans held for sale and MSR hedging activity for the nine months ended September 30, 2025, compared to a net loss of $7 million for the nine months ended September 30, 2024.

Current report

•Non-interest expense was $1.0 billion for the nine months ended September 30, 2025, as compared to $838 million for the nine months ended September 30, 2024. The increase was primarily driven by an $88 million increase in merger and restructuring expense to $109 million, primarily related to the Pacific Premier acquisition, one month of combined operations, higher salaries and employee benefits, increased software costs, and a $55 million accrual for a legal settlement.

Current report

•Total loans and leases were $48.5 billion as of September 30, 2025, an increase of $10.8 billion as compared to December 31, 2024. The increase was driven by loans acquired through the Pacific Premier acquisition, partially offset by runoff in commercial development and transactional loans, as well as the transfer of $282 million in residential real estate loans to held-for-sale.

Current report

•Total deposits were $55.8 billion as of September 30, 2025, an increase of $14.1 billion as compared to December 31, 2024. The growth was driven by the addition of Pacific Premier deposits and organic increases from recent small business and retail deposit campaigns, partially offset by a reduction in brokered deposits.

Current report

•The ACL was $492 million as of September 30, 2025, an increase of $51 million from December 31, 2024. The change reflects loan growth from the Pacific Premier acquisition, updated economic forecasts incorporated into credit models, and includes $5 million related to PCD loans booked at closing, which did not impact earnings.

Current report

•Provision for credit losses was $70 million and $127 million for the three and nine months ended September 30, 2025, as compared to $30 million for the three months ended June 30, 2025 and $78 million for the nine months ended September 30, 2024. The increase in the provision includes an initial provision for acquired non-PCD loans and unfunded commitments and recalibration of credit models to incorporate Pacific Premier's historical data, and changes in economic forecasts used in the ACL methodology.

Current report

•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 will expire on November 30, 2026. The timing and amount of common share repurchases will be at the discretion of senior management and subject to various factors, including, without limitation, Columbia’s capital position, financial performance, market conditions, and regulatory considerations. Columbia’s strong capital position supports the expansion of a capital return strategy. We anticipate continued profitability and capital generation, enabling us to execute share repurchases while investing in organic growth and optimizing the balance sheet, consistent with our long-term commitment to shareholder value.

Current report

As a result of the recent acquisition, the Company has identified a new critical accounting estimate related to the fair value measurement of assets acquired and liabilities assumed. Management believes the estimates and assumptions used in determining these fair values, particularly for loans, intangible assets, and goodwill, are significant to understanding the Company's financial condition and results of operations. These estimates require complex and subjective judgments, and accordingly, management considers them to be critical accounting estimates.

Current report

The Company accounts for business combinations using the acquisition method of accounting. Under this approach, the acquired company's assets and liabilities are recorded at fair value as of the acquisition date, except where otherwise specified by applicable accounting standards. Any excess of the purchase price over the fair value of net identifiable assets is recognized as goodwill. The operating results of the acquired entity are included in the Company's financial statements beginning on the acquisition date.

Current report

Management applies significant judgment and estimates in valuing acquired assets and liabilities, including assumptions related to projected cash flows, repayment and default rates, discount rates, and realizable collateral values. For PCD loans, the ACL is recognized at acquisition. For non-PCD assets, the ACL is recorded as a provision for credit losses in the same reporting period. Fair value adjustments are subsequently amortized or accreted over the estimated life of the related assets or liabilities.

Current report

Fair value determinations may involve the use of third-party valuation specialists and are based on management's assumptions regarding growth rates, customer attrition, market-based earnings multiples, and other relevant factors. Preliminary fair values may be adjusted post-acquisition if new information becomes available about conditions that existed at the acquisition date. Such adjustments are recognized in the reporting period in which they are identified.

Current report

Valuation of certain assets and liabilities, such as loans, deposits, and identifiable intangibles, may involve significant judgment due to the absence of active markets. Changes in assumptions or adverse economic conditions could materially affect these valuations, including goodwill, and may result in future impairment charges.

Current report

For the nine months ended September 30, 2025, the Company had net income of $335 million, compared to net income of $390 million for the same period in the prior year. The decrease in net income was mainly attributable to an increase in non-interest expense and provision for credit losses, partially offset by increases in net interest income and non-interest income. Non-interest expense increased $173 million, primarily driven by increased merger and restructuring expenses, salaries and employee benefits, and software expenses, associated with the acquisition, as well as a $55 million accrual for a legal settlement. The provision increased mainly due to an initial provision for acquired non-PCD loans and unfunded commitments and a recalibration of our models to incorporate historical Pacific Premier data into our ACL assumptions, where applicable. The increase of $95 million in net interest income reflects lower funding costs, partially offset by lower interest income in the period.

Current report

Net interest income for the three months ended September 30, 2025 was $505 million, an increase of $59 million compared to the three months ended June 30, 2025. The increase was driven by a $70 million increase in interest income, largely reflective of the impact of one month as a combined company in the current period, partially offset by an increase in interest expense due to the addition of deposit balances from the acquisition of Pacific Premier.

Current report

The net interest margin (net interest income as a percentage of average interest-earning assets) on a fully tax-equivalent basis was 3.84% for the three months ended September 30, 2025, as compared to 3.75% for the three months ended June 30, 2025. The increase primarily reflects the impact of one month as a combined company in the current period as well as lower cost of interest-bearing deposits. A favorable shift in Columbia's funding mix also contributed to the increase.

Current report

The cost of interest-bearing deposits for the three months ended September 30, 2025 was 2.43%, a decrease of 9 basis points compared to the three months ended June 30, 2025, reflecting our proactive management of deposit rates ahead of and following a 25-basis point reduction in the federal funds rate in mid-September, and a reduction in higher-cost brokered deposits during the period. The cost of interest-bearing deposits in September also benefited from the amortization of a premium related to Pacific Premier's time deposits, which will continue through December 31, 2025 at an equivalent monthly amount. The amortization contributed $4 million to net interest income during September, and favorably impacted deposit rates. The cost of interest-bearing liabilities for the three months ended September 30, 2025 was 2.65%, a decrease of 13 basis points compared to the three months ended June 30, 2025.

Current report

The increase in non-interest income is generally attributable to one month of combined operations following the acquisition of Pacific Premier. Quarterly changes in fair value adjustments also contributed to the increase in non-interest income between periods.

Current report

The increase in non-interest expense is generally attributable to there being one month of higher expense as result of the acquisition of Pacific Premier, which included one month of combined operations.

Current report

Salaries and employee benefits increased during the three months ended September 30, 2025, as compared to the three months ended June 30, 2025, driven by additional expenses associated with the larger employee base as a result of the acquisition of Pacific Premier, with one month as a combined organization.

Current report

Deposit costs increased during the three months ended September 30, 2025, as compared to the three months ended June 30, 2025, primarily related to one month of combined operations, with HOA-related fees being the driver of the increase. HOA deposit costs primarily reflect pricing arrangements with third-party entities that manage HOA accounts. These costs are variable and tied to account activity and transaction volume. This upward trend is expected to continue, as HOA-related fees are expected to be $10 million quarterly. Columbia's acquisition of Pacific Premier expanded the Company's HOA banking business, which contributes low-cost deposits to our funding base and provides other business-generating opportunities.

Current report

Intangible amortization increased during the three months ended September 30, 2025, as compared to the three months ended June 30, 2025, due to amortization of the core deposit intangibles associated with the acquisition of Pacific Premier. This upward trend is expected to continue; refer to Note 6 -Goodwill and Other Intangible Assets for the table detailing expected amortization expense for intangible assets.

Current report

Merger and restructuring expense increased during the three months ended September 30, 2025, as compared to the three months ended June 30, 2025, driven by personnel costs and legal and professional fees. Merger and restructuring expenses are expected to remain elevated through system integration in the first quarter of 2026. Post-integration, we anticipate realizing cost synergies that will reduce overall expense levels.

Current report

Salaries and employee benefits increased during the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024, driven by additional expenses associated with the larger employee base as a result of the acquisition of Pacific Premier, with one month as a combined organization, as well as increases to incentive payouts and compensation costs related to stock awards.

Current report

Occupancy and equipment, net increased during the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024, primarily due to an increase in branch locations and software costs related to the acquisition of Pacific Premier.

Current report

Merger and restructuring expense increased during the nine months ended September 30, 2025, as compared to the nine months ended September 30, 2024, driven by personnel costs and legal and professional fees. Refer to Note 2 –Business Combinationsfor the breakout of acquisition expenses.

Current report

Total loans and leases outstanding as of September 30, 2025 were $48.5 billion, an increase of $10.8 billion as compared to December 31, 2024. The increase was driven by $11.4 billion in loans acquired through the Pacific Premier acquisition, partially offset by runoff in commercial development and transactional loans, as well as the transfer of $282 million in residential mortgage loans to held-for-sale. The loan-to-deposit ratio was 87% and 90% as of September 30, 2025 and December 31, 2024, respectively.

Current report

The ACL represents management's best estimate of lifetime credit losses for loans and leases and unfunded commitments. The ACL totaled $492 million as of September 30, 2025, an increase of $51 million from $441 million as of December 31, 2024. The increase in the ACL during the three and nine months ended September 30, 2025, reflect the addition of the Pacific Premier loan portfolio, which contributed to a $10.8 billion increase in total loans and leases held for investment. The ACL reflects $70 million provision for credit losses attributed to the acquired non-PCD loans and unfunded commitments and includes $5 million related to Pacific Premier PCD loans booked at acquisition closing and updated economic forecasts incorporated into credit models. Offsetting adjustments were recognized at both the Bank and FinPac, reflecting routine provisioning and recapture activity within the overall allowance methodology.

Current report

Total deposits were $55.8 billion as of September 30, 2025, an increase of $14.1 billion as compared to December 31, 2024. The increase was due to the acquisition of Pacific Premier and organic growth in customer deposits, partially offset by a decrease in brokered deposits.

Current report

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 will expire on November 30, 2026. The timing and amount of common share repurchases will be at the discretion of senior management and subject to various factors, including, without limitation, Columbia’s capital position, financial performance, market conditions, and regulatory considerations.

Previous report

•Earnings per diluted common share was $0.73 for the three months ended June 30, 2025, as compared to $0.41 for the three months ended March 31, 2025. The increase for the three months ended June 30, 2025, as compared to the prior period, was primarily driven by a decrease in non-interest expense, as the prior period included a $55.0 million accrual for a legal settlement and $14.6 million in severance expense not repeated in the current quarter. Higher net interest income also contributed to the increase in earnings per diluted common share between periods.

Previous report

•Net interest margin, on a tax-equivalent basis, was 3.75% for the three months ended June 30, 2025, as compared to 3.60% for the three months ended March 31, 2025, due primarily to higher earning asset yields. Net interest income was $446.4 million for the three months ended June 30, 2025, an increase of $21.5 million compared to the three months ended March 31, 2025. The increase reflects higher interest income earned on loans and investment securities and relatively stable funding costs.

Previous report

•Non-interest income was $64.5 million for the three months ended June 30, 2025, as compared to $66.4 million for the three months ended March 31, 2025. The decrease was driven by changes in fair value adjustments, which include adjustments in fair value for certain loans held for investment and MSR hedging activity due to rate changes, which collectively resulted in a net fair value loss of $640,000 in the three months ended June 30, 2025, compared to a net fair value gain of $9.5 million in the prior period. The change between periods was partially offset by higher core fee-generating businesses, including card-based fee income, swap-related income, and financial services and trust revenue.

Previous report

•Non-interest expense was $278.0 million for the three months ended June 30, 2025, down $62.1 million as compared to the three months ended March 31, 2025, which included a $55.0 million accrual for a legal settlement and $14.6 million in severance expense recorded in merger and restructuring expense that was not repeated in the current quarter.

Previous report

•Net interest margin, on a tax-equivalent basis, was 3.67% for the six months ended June 30, 2025, as compared to 3.54% for the six months ended June 30, 2024. The increase for the six months ended June 30, 2025 compared to the prior year period was due to lower funding costs, which were partially offset by lower earning asset yields due to fluctuating interest rates and product repricing between the periods. A favorable balance sheet mix shift to lower-cost customer deposits from higher-cost wholesale funding sources between periods contributed positively to net interest margin. Net interest income increased $20.6 million for the six months ended June 30, 2025, compared to the six months ended June 30, 2024, due to the same factors that impacted net interest margin, partially offset by slight contraction in the balance of average interest-earning assets between periods.

Previous report

•Non-interest income was $130.8 million for the six months ended June 30, 2025, as compared to $95.1 million for the six months ended June 30, 2024. The increase was mainly due to fluctuations in fair value adjustments for certain loans held for sale and MSR hedging activity, which collectively resulted in a favorable change due to a net fair value gain of $8.8 million for the six months ended June 30, 2025, compared to a net fair value loss of $13.6 million for the six months ended June 30, 2024.

Previous report

•Non-interest expense was $618.1 million for the six months ended June 30, 2025, as compared to $566.8 million for the six months ended June 30, 2024. The increase for the six months ended June 30, 2025 is mainly related to a $55.0 million accrual for a legal settlement and $14.6 million in severance expense recorded in merger and restructuring expense recorded in the first quarter. This increase was partially offset by lower FDIC assessment fees and intangible amortization during the period.

Previous report

•Total loans and leases were $37.6 billion as of June 30, 2025, a decrease of $43.9 million, as compared to December 31, 2024. The decrease in total loans and leases was primarily in residential and commercial loan balances, partially offset by an increase in CRE balances. The contraction was driven by loan payoffs and slower origination volume, partially offset by draws in CRE construction loans and growth in owner-occupied term CRE balances.

Previous report

•Total deposits were $41.7 billion as of June 30, 2025, an increase of $21.9 million, as compared to December 31, 2024. The increase was due to our recent small business and retail deposits campaign, as well as an increase in brokered deposits, partially offset by a decrease in customer deposits, due in part to seasonally anticipated customer tax payments and owner distributions. Customers also continue to use their own cash to make investments in their businesses or pay down debt.

Previous report

•The ACL was $439.0 million as of June 30, 2025, a decrease of $1.8 million compared to December 31, 2024. The decrease in the ACL reflects credit migration trends, changes in the economic assumptions used in credit models and decreases in loan portfolio balances during the period.

Previous report

•The Company had a provision for credit losses of $29.4 million and $56.9 million for the three and six months ended June 30, 2025. This compares to a provision for credit losses of $27.4 million for the three months ended March 31, 2025 and $49.0 million for the six months ended June 30, 2024. The increase for the three and six months ended June 30, 2025 compared to the prior periods was mainly due to credit migration trends, charge-off activity, and changes in the economic forecasts used in credit models.

Previous report

For the six months ended June 30, 2025, the Company had net income of $239.0 million, compared to net income of $244.2 million for the same period in the prior year. The decrease in net income was mainly attributable to an increase in non-interest expense, partially offset by increases in non-interest income and net interest income. The $51.4 million increase in non-interest expense was primarily driven by a $55.0 million accrual for a legal settlement and $14.6 million in severance expense recorded in merger and restructuring expense, partially offset by decreases in FDIC assessment fees and intangible amortization. The increase of $35.8 million in non-interest income was primarily driven by favorable fluctuations in fair value adjustments, which include adjustments in fair value for certain loans held for investment and MSR hedging activity. These adjustments resulted in a net fair value gain of $8.8 million in the six months ended June 30, 2025, compared to a net fair value loss of $13.6 million in the prior period, driven by changes in interest rates during the periods as well as growth in other core fee-generating businesses, including swap-related income, financial services and trust revenue, and treasury management fees. The increase of $20.6 million in net interest income reflects lower funding costs, only partially offset by lower interest income in the period.

Previous report

Net interest income for the three months ended June 30, 2025 was $446.4 million, an increase of $21.5 million compared to the three months ended March 31, 2025. The increase was driven by a $23.4 million increase in interest income, mainly on loans and investment securities, and relatively stable funding costs.

Previous report

The net interest margin (net interest income as a percentage of average interest-earning assets) on a fully tax-equivalent basis was 3.75% for the three months ended June 30, 2025, as compared to 3.60% for the three months ended March 31, 2025. Net interest margin benefited from an increase in the yield on taxable investment securities to 4.22% for the three months ended June 30, 2025, from 3.72% for the three months ended March 31, 2025. The increase is due to higher prepayment speeds and the purchase of higher-yielding investment securities during the quarter. The average yield on the loan portfolio increased 8 basis points between periods to 6.00% for the three months ended June 30, 2025, due primarily to higher yields on commercial and construction loans. Loan yields also benefited from a $1.6 million interest recovery recorded during the month of June 2025 related to a non-performing loan that repaid in full. The cost of interest-bearing deposits was unchanged between periods at 2.52% for the second quarter of 2025. The cost of interest-bearing liabilities for the three months ended June 30, 2025 was 2.78%, a decrease of 2 basis points compared to the three months ended March 31, 2025.

Previous report

Gain on certain loans held for investment, at fair value for the three months ended June 30, 2025, as compared to the three months ended March 31, 2025, decreased due to interest rate fluctuations between periods that resulted in a gain on the fair value of certain loans held for investment of $212,000, as compared to a gain of $7.0 million for the prior quarter.

Previous report

Salaries and employee benefits increased during the three months ended June 30, 2025, as compared to the three months ended March 31, 2025, driven by compensation accruals to salaries, annual merit increases, and incentive payouts earned during the quarter.

Previous report

Merger and restructuring expense decreased during the three months ended June 30, 2025, as compared to the three months ended March 31, 2025, mainly due to a decrease in restructuring expense as compared to the prior period, which included higher severance expense. The three months ended June 30, 2025 includes higher merger-related expense related to Columbia’s pending acquisition of Pacific Premier, as compared to the three months ended March 31, 2025. This upward trend is expected to continue as merger and integration activities progress.

Previous report

Total loans and leases outstanding as of June 30, 2025 were $37.6 billion, a decrease of $43.9 million as compared to December 31, 2024. The decrease was primarily in residential and commercial loan balances, partially offset by an increase in CRE balances. The contraction was driven by loan payoffs and slower origination volume, partially offset by draws in CRE construction loans and growth in owner-occupied term CRE balances. The loan to deposit ratio was 90% at both June 30, 2025 and December 31, 2024.

Previous report

The ACL represents management's best estimate of lifetime credit losses for loans and leases and unfunded commitments. The ACL totaled $439.0 million as of June 30, 2025, a decrease of $1.8 million from $440.8 million as of December 31, 2024. The changes in the ACL estimate during the three and six months ended June 30, 2025, reflect credit migration trends, changes in the economic assumptions used in the credit models, and a recalibration of the CRE, residential mortgage, and home equity line of credit CECL models in the first quarter of 2025.

Previous report

Total deposits were $41.7 billion as of June 30, 2025, an increase of $21.9 million as compared to December 31, 2024. The increase was due to our recent small business and retail deposits campaign, as well as an increase in brokered deposits, partially offset by a decrease in customer deposits, due in part to seasonally anticipated customer tax payments and owner distributions. Customers also continue to use their own cash to make investments in their businesses or pay down debt.

Previous wording

•Earnings per diluted common share was $1.14 for the six months ended June 30, 2025, as compared to $1.17 for the six months ended June 30, 2024. The decrease for the six months ended June 30, 2025, as compared to the prior year period, was primarily driven by an increase in non-interest expense, due to the litigation accrual and severance, as noted above. Higher non-interest income and net interest income partially offset the increase in non-interest expense.

Current wording

•Earnings per diluted common share was $0.40 for the three months ended September 30, 2025, as compared to $0.73 for the three months ended June 30, 2025. The decrease was primarily attributable to higher non-interest expense, largely driven by merger and restructuring expenses related to the acquisition of Pacific Premier, as well as an increase in provision expense due to the initial provision for non-PCD loans acquired from Pacific Premier. These impacts were partially offset by higher net interest income, reflecting one month of income from the combined organization.

Previous wording

Previous wording

The Company had net income of $152.4 million for the three months ended June 30, 2025, compared to net income of $86.6 million for the three months ended March 31, 2025. The increase in net income was mainly attributable to a decrease of $62.1 million in non-interest expense, which related to a $55.0 million accrual for a legal settlement and $14.6 million in severance expense recorded in merger and restructuring expense in the first quarter of 2025 that was not repeated in the current quarter. There was also an increase of $21.5 million in net interest income reflecting higher interest income earned on loans and investment securities and relatively stable funding costs as compared to the prior quarter.

Current wording

The Company had net income of $96 million for the three months ended September 30, 2025, compared to net income of $152 million for the three months ended June 30, 2025. The decrease in net income was mainly attributable to an increase of $115 million in non-interest expense, due mainly to higher merger and restructuring expense, as well as higher expense as a result of the acquisition of Pacific Premier, which included one month of combined operations. There was also an increase in the provision driven by the $70 million initial provision related to non-PCD loans and unfunded commitments from the acquisition of Pacific Premier. The decrease in net income was partially offset by an increase of $59 million in net interest income reflecting the impact of one month as a combined company in the current period.

Previous wording

Net interest income for the six months ended June 30, 2025 was $871.4 million, an increase of $20.6 million compared to the six months ended June 30, 2024. The change in net interest income was mainly due to lower interest rates, driven by the reductions in the federal funds rate in the latter half of 2024, which resulted in lower rates on interest-bearing liabilities, almost completely offset by lower yields on interest-earning assets for the six months ended June 30, 2025 compared to the prior year period.

Current wording

Net interest income for the nine months ended September 30, 2025 was $1.4 billion, an increase of $95 million compared to the nine months ended September 30, 2024. The increase in net interest income was driven by a decrease of $116 million in interest expense mainly due to lower interest rates driven by the reductions in the federal funds rate of 125 basis points since the first part of 2024, which resulted in lower rates on interest-bearing liabilities, partially offset by lower yields on interest-earning assets for the nine months ended September 30, 2025 compared to the prior-year period.

Previous wording

The net interest margin on a fully tax-equivalent basis was 3.67% for the six months ended June 30, 2025, as compared to 3.54% for the six months ended June 30, 2024. The increase for the six months ended June 30, 2025 compared to the prior year period was due to lower funding costs, partially offset by lower earning yields. A favorable balance sheet mix shift to lower-cost customer deposits from higher-cost wholesale funding sources between periods contributed positively to net interest margin. The yield on loans and leases for the six months ended June 30, 2025 and 2024 was 5.96% and 6.17%, respectively, a decrease of 21 basis points, primarily due to the declining rate environment. The cost of interest-bearing liabilities was 2.79% for the six months ended June 30, 2025, compared to 3.28% for the six months ended June 30, 2024, a decrease of 49 basis points, due to the reductions in the federal funds rate and the favorable balance sheet mix shift.

Current wording

The net interest margin on a fully tax-equivalent basis was 3.73% for the nine months ended September 30, 2025, as compared to 3.55% for the nine months ended September 30, 2024. The increase for the nine months ended September 30, 2025 compared to the prior year period was due primarily to lower funding costs, partially offset by lower earning yields. A favorable balance sheet mix shift to lower-cost customer deposits from higher-cost wholesale funding sources between periods contributed positively to net interest margin. The cost of interest-bearing liabilities was 2.74% for the nine months ended September 30, 2025, compared to 3.28% for the nine months ended September 30, 2024, a decrease of 54 basis points, due mainly to a favorable shift in Columbia's funding mix and reductions in the federal funds rate. The yield on loans and leases for the nine months ended September 30, 2025 and 2024 was 5.96% and 6.18%, respectively, a decrease of 22 basis points, primarily due to the declining rate environment, partially offset by a relative increase in average loan balances as a percentage of average earning asset balances.

Previous wording

The Federal Reserve lowered the target range for the federal funds rate by 0.50% in September 2024 and an additional 0.25% in both November and December 2024. In the 2025 meetings, the Federal Reserve maintained the target rate at 4.25%-4.50%. The balance sheet remained in a slightly liability-sensitive position as of June 30, 2025. We expect customer deposit balance trends to be a driver of net interest margin performance, as we continue to target a lower funding contribution from wholesale sources, like FHLB Advances and brokered deposits.

Typically, loans in a non-accrual status will not have an ACL as they will be written down to their net realizable value or charged off. However, the net realizable value for homogeneous leases and equipment finance agreements are determined by the LGD calculated by the CECL model, and therefore homogeneous leases and equipment finance agreements on non-accrual will have an ACL amount until they become 181 days past due, at which time they are charged off. The non-accrual leases and equipment finance agreements of $19.4 million as of June 30, 2025 have a related ACL of $17.2 million, with the remaining loans written-down to the estimated fair value of the collateral, less estimated costs to sell, and are expected to be resolved with no additional material loss, absent further decline in market prices.

Delinquency and non-accrual loan movements during the period reflect an anticipated move toward a normalized credit environment following a phase of exceptional high credit quality.

Previous wording

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 June 30, 2025, approximately 27.1% of the outstanding principal balance of our CRE loan portfolio, which includes multifamily properties, were secured by owner-occupied properties.

Loans secured by multifamily properties, including construction, represented 19% of the total loan portfolio at 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 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.
