CEO Commentary

"Our third quarter results reflect our continued work and success as we strive toward top-quartile performance," said Clint Stein, President and CEO. "Our recurring expense run rate reflects a 25% reduction in costs over the 18 months we have operated as a combined organization, as we eliminated redundancies and streamlined operations. Our teams' dedication to driving value for our customers contributed to solid core deposit growth, even as deposit costs were reduced. Although loan balances contracted during the quarter, they reflect healthy customer activity and our focus on reducing transactional assets and their funding sources, as we regain Columbia's placement as a top-performing bank that delivers long-term, consistent, repeatable results for our shareholders."

-Clint Stein, President and CEO of Columbia Banking System, Inc.

3Q24 HIGHLIGHTS (COMPARED TO 2Q24)

Net Interest Income and NIM	• Net interest income increased by $3 million from the prior quarter due to higher income earned on loans, which occurred despite a reduction in accretion income, and relatively stable funding costs prior to the late-quarter reduction in the federal funds rate.
Net Interest Income and NIM	• Net interest margin was 3.56%, unchanged from the prior quarter, as a favorable balance sheet funding mix shift into lower-cost deposits and a slight increase in loan yields offset a lower yield on securities.

Non-Interest Income and Expense	• Non-interest income increased by $21 million due to the quarterly fluctuation in cumulative fair value accounting and hedges, which drove $16 million of the change. Higher core banking activity contributed to the remaining increase.
Non-Interest Income and Expense	• Non-interest expense decreased by $8 million due to lower restructuring expense and a $6 million decline in salary and wages expense related to operational initiatives. The effect was partially offset by the prior quarter's reversal of compensation-related accruals, which did not repeat in the third quarter.

Credit Quality	• Net charge-offs were 0.31% of average loans and leases (annualized), compared to 0.32% in the prior quarter. Lower activity in the FinPac portfolio drove the decline.
	• Provision expense of $29 million compares to $32 million in the prior quarter.
	• Non-performing assets to total assets was 0.32%, compared to 0.30% as of June 30, 2024.

Capital	• Estimated total risk-based capital ratio of 12.5% and estimated common equity tier 1 risk-based capital ratio of 10.3%.
Capital	• Declared a quarterly cash dividend of $0.36 per common share on August 12, 2024, which was paid September 9, 2024.

Notable Items	• Realized $82 million in annualized cost savings associated with recent operational initiatives as of September 30, 2024. Reinvestment of $12 million in savings is ongoing and expected to extend into 2025.
Notable Items	• Opened our second retail branch in Arizona, which will be complemented by a planned third location in the state, slated to open in early 2025.

Organizational Update
Columbia Banking System, Inc. ("Columbia," the "Company," "we," or "our") completed an enterprise-wide evaluation of our operations during the first quarter of 2024. Cost savings identified through the comprehensive review were fully realized as of September 30, 2024, with a portion reserved to fund franchise reinvestment into 2025. Planned reinvestments, some of which have already occurred, include new talent additions, opening de novo locations in targeted growth markets within our existing footprint, and investments in products and technology that create operational efficiencies and revenue growth opportunities. During the third quarter, Columbia's primary subsidiary, Umpqua Bank ("Umpqua"), added new team members with specialty focuses in three of our markets. We also announced the opening of a retail branch in Scottsdale, Arizona, which will be complemented by a planned location in Mesa, Arizona, slated to open in early 2025 as our third branch in the Phoenix metropolitan area. Please refer to the Q3 2024 Earnings Presentation for additional details on our cost savings initiatives and planned reinvestments.

On February 28, 2023, Columbia completed its merger with Umpqua Holdings Corporation ("UHC"), combining the two premier banks in the Northwest to create one of the largest banks headquartered in the West (the "merger"). Columbia's financial results for any periods ended prior to February 28, 2023 reflect UHC results only on a standalone basis. In addition, Columbia's reported financial results for the nine months ended September 30, 2023 reflect UHC financial results only until the closing of the merger after the close of business on February 28, 2023. As a result of these two factors, Columbia's financial results for the nine months ended September 30, 2024 may not be directly comparable to prior reported periods. Under the reverse acquisition method of accounting, the assets and liabilities of Columbia as of February 28, 2023 ("historical Columbia") were recorded at their respective fair values.

Net Interest Income
Net interest income was $430 million for the third quarter of 2024, up $3 million from the prior quarter. The increase reflects higher income earned on loans, which occurred despite a reduction in accretion income, and relatively stable funding costs prior to the reduction in the federal funds rate in the latter part of September.

Columbia's net interest margin was 3.56% for the third quarter of 2024, unchanged from the second quarter of 2024. A favorable balance sheet funding mix shift into lower-cost deposits and a slight increase in loan yields offset a lower yield on securities, contributing to net interest margin stability between periods. The cost of interest-bearing deposits decreased 2 basis points from the prior quarter to 2.95% for the third quarter of 2024, which compares to 2.90% for the month of September and 2.74% as of September 30, 2024. "Anticipated seasonal deposit inflows and successful small business campaigns contributed to customer balance growth during the third quarter," commented Tory Nixon, President of Umpqua Bank. "We continue to use bundled solutions to generate lower-cost customer deposit balances, not promotional pricing. Overall deposit pricing was reduced ahead of and following the federal funds rate reduction in September."

Columbia's cost of interest-bearing liabilities decreased 2 basis points from the prior quarter to 3.29% for the third quarter of 2024, which compares to 3.26% for the month of September and 3.13% as of September 30, 2024. Please refer to the Q3 2024 Earnings Presentation for additional net interest margin change details and interest rate sensitivity information as well as to our non-GAAP disclosures in this press release for the impact of purchase accounting accretion and amortization on individual line items.

Non-interest Income
Non-interest income was $66 million for the third quarter of 2024, up $21 million from the prior quarter. The increase was driven by quarterly fluctuations in fair value adjustments and mortgage servicing rights ("MSR") hedging activity, which collectively resulted in a net fair value gain of $7 million in the third quarter compared to a net fair value loss of $10 million in the second quarter, as detailed in our non-GAAP disclosures. Excluding these items, non-interest income was up $5 million² between periods due primarily to higher swap and mortgage banking income and last quarter's $2 million loss on loan sales, which did not repeat in the third quarter. Treasury management fees, a component of service charges on deposits, increased by 2% from the prior quarter and by 12% for the nine months ended September 30, 2024 compared to the nine months ended September 30, 2023.

Non-interest Expense
Non-interest expense was $271 million for the third quarter of 2024, down $8 million from the prior quarter. Excluding merger and restructuring expense, exit and disposal costs, and accruals for the FDIC special assessment, non-interest expense was $268 million [2], up $6 million from the prior quarter, which included an $8 million reversal of prior compensation-related accruals that did not repeat in the third quarter. Salary and wages expense was down $6 million from the prior quarter, due largely to staff reductions that took place throughout the second quarter of 2024, with some of the benefit offset by higher group insurance costs. Please refer to the Q3 2024 Earnings Presentation for additional expense details.

Balance Sheet
Total consolidated assets were $51.9 billion as of September 30, 2024, down slightly from $52.0 billion as of June 30, 2024. Cash and cash equivalents were $2.1 billion as of September 30, 2024, essentially unchanged from June 30, 2024. Including secured off-balance sheet lines of credit, total available liquidity was $19.4 billion as of September 30, 2024, representing 37% of total assets, 47% of total deposits, and 138% of uninsured deposits. Available-for-sale securities, which are held on balance sheet at fair value, were $8.7 billion as of September 30, 2024, an increase of $174 million relative to June 30, 2024, as the increase in the fair value of the portfolio more than offset paydowns. Please refer to the Q3 2024 Earnings Presentation for additional details related to our securities portfolio and liquidity position.

Gross loans and leases were $37.5 billion as of September 30, 2024, a decrease of $207 million relative to June 30, 2024. "Healthy business activity, like loan payoffs related to business and property sales and project completions, contributed to the quarter's loan contraction," commented Mr. Nixon. "Balances also declined as a result of our strategic decision to allow transactional loans to trend lower as we organically remix the portfolio into relationship-driven commercial loans." Please refer to the Q3 2024 Earnings Presentation for additional details related to our loan portfolio, which include underwriting characteristics, the composition of our commercial portfolios, and disclosure related to our office portfolio.

Customer deposit growth of $602 million enabled a 20% reduction in brokered CDs during the third quarter of 2024. Total deposits were $41.5 billion as of September 30, 2024, essentially unchanged from June 30, 2024, as a result of the intentional reduction in wholesale funding balances. Please refer to the Q3 2024 Earnings Presentation for additional details related to deposit characteristics and flows.

Credit Quality
The allowance for credit losses was $438 million, or 1.17% of loans and leases, compared to $439 million, or 1.16% of loans and leases, as of June 30, 2024. The provision for credit losses was $29 million for the third quarter of 2024, and it reflects credit migration trends, charge-off activity, and changes in the economic forecasts used in credit models.

Net charge-offs were 0.31% of average loans and leases (annualized) for the third quarter of 2024, compared to 0.32% for the second quarter of 2024. Net charge-offs in the FinPac portfolio were $20 million in the third quarter, down $5 million from the second quarter as lower delinquencies in the transportation sector of the portfolio resulted in lower charge-off activity. Net charge-offs excluding the FinPac portfolio were $9 million in the third quarter. Non-performing assets were $168 million, or 0.32% of total assets, as of September 30, 2024, compared to $156 million, or 0.30% of total assets, as of June 30, 2024. Please refer to the Q3 2024 Earnings Presentation for additional details related to the allowance for credit losses and other credit trends.

Capital
Columbia's book value per common share was $25.17 as of September 30, 2024, compared to $23.76 as of June 30, 2024. The change reflects organic net capital generation and a favorable change in accumulated other comprehensive (loss) income ("AOCI") to $(234) million at September 30, 2024, compared to $(456) million at the prior quarter-end. The change in AOCI is due primarily to a decrease in the tax-effected net unrealized loss on available-for-sale securities to $219 million as of September 30, 2024, compared to $442 million as of June 30, 2024. Tangible book value per common share³was $17.81 as of September 30, 2024, compared to $16.26 as of June 30, 2024.

Columbia's estimated total risk-based capital ratio was 12.5% and its estimated common equity tier 1 risk-based capital ratio was 10.3% as of September 30, 2024, compared to 12.2% and 10.0%, respectively, as of June 30, 2024. Columbia remains above current "well-capitalized" regulatory minimums. The regulatory capital ratios as of September 30, 2024 are estimates, pending completion and filing of Columbia's regulatory reports.

⁽⁶⁾	Non-interest expense adjustments were revised subsequent to the Company's reporting of its earnings results for the period ended December 31, 2023. The revision includes adding the FDIC special assessment to the non-interest expense adjustments, which removes the special assessment from the Company's calculation of operating non-interest expense. The Company views the special assessment as an infrequent expense that is outside the control of the Company.

The Company believes presenting certain non-GAAP financial measures provides investors with information useful in understanding our financial performance, our performance trends, and our financial position. We utilize these measures for internal planning and forecasting purposes, and operating pre-provision net revenue and operating return on tangible common equity are also used as part of our incentive compensation program for our executive officers. We, as well as securities analysts, investors, and other interested parties, also use these measures to compare peer company operating performance. We believe that our presentation and discussion, together with the accompanying reconciliations, provides a complete understanding of factors and trends affecting our business and allows investors to view performance in a manner similar to management. These non-GAAP measures should not be considered a substitution for GAAP basis measures and results, and we strongly encourage investors to review our consolidated financial statements in their entirety and not to rely on any single financial measure. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies' non-GAAP financial measures having the same or similar names.

⁽¹⁾	Tax-exempt interest was adjusted to a taxable equivalent basis using a 21% tax rate and added to stated revenue for this calculation.
⁽²⁾	Non-interest expense adjustments were revised subsequent to the Company's reporting of its earnings results for the period ended December 31, 2023. The revision includes the FDIC special assessment in non-interest expense adjustments, which removes the special assessment from the Company's calculation of operating non-interest expense. The Company views the special assessment as an infrequent expense that is outside the control of the Company.
⁽³⁾	The operating efficiency ratio was adjusted in the first quarter of 2024 to remove B&O taxes and for a tax-equivalent adjustment to BOLI income. The Company views the adjusted operating efficiency ratio as a better representation of its efficiency ratio when compared to other banks as it normalizes for the tax treatment of the adjusted items. The adjustment re-aligns Columbia's calculation of its operating efficiency ratio with its pre-merger calculation.

⁽¹⁾	Tax-exempt interest was adjusted to a taxable equivalent basis using a 21% tax rate and added to stated revenue for this calculation.
⁽²⁾	Non-interest expense adjustments were revised subsequent to the Company's reporting of its earnings results for the period ended December 31, 2023. The revision includes the FDIC special assessment in non-interest expense adjustments, which removes the special assessment from the Company's calculation of operating non-interest expense. The Company views the special assessment as an infrequent expense that is outside the control of the Company.
⁽³⁾	The operating efficiency ratio was adjusted in the first quarter of 2024 to remove B&O taxes and for a tax-equivalent adjustment to BOLI income. The Company views the adjusted operating efficiency ratio as a better representation of its efficiency ratio when compared to other banks as it normalizes for the tax treatment of the adjusted items. The adjustment re-aligns Columbia's calculation of its operating efficiency ratio with its pre-merger calculation.
