TACOMA, Wash., Oct. 20, 2022 /PRNewswire/ -- Columbia Banking System, Inc. (NASDAQ: COLB) ("Columbia", "we" or "us"), the parent company of Columbia Bank (the "Bank"), released earnings for the third quarter of $64.9 million and diluted earnings per share of $0.83. Clint Stein, President and Chief Executive Officer said today upon the release of Columbia's earnings, "Record quarterly revenue and earnings were the result of our bankers remaining laser focused on our clients as they worked to expand their businesses and investments." He continued, "By anticipating changes within our markets and continuously working to scale our operations, we were successful in meeting our clients' needs and in growing market share."

Balance Sheet

Total assets at September 30, 2022 were $20.41 billion, a decrease of $159.0 million from the linked quarter. Loans were $11.69 billion, up $369.9 million from June 30, 2022, mainly attributable to loan originations of $598.1 million partially offset by loan payments. Debt securities in total were $6.78 billion, a decrease of $491.7 million from $7.27 billion at June 30, 2022 substantially driven by fair value movement related to the available-for-sale portfolio. Total deposits at September 30, 2022 were $17.94 billion, a decrease of $15.6 million from June 30, 2022. The deposit mix remained fairly consistent from June 30, 2022 with 50% noninterest-bearing and 50% interest-bearing.

Chris Merrywell, Columbia's Executive Vice President and Chief Operating Officer, stated, "Columbia's value proposition continues to be well-received by existing and new clients." He continued, "Our bankers' steadfast focus on anticipating and meeting our customers' needs drove robust loan growth during the quarter and maintained our low-cost deposit funding base."

Income Statement

Net Interest Income

Net interest income for the third quarter of 2022 was $162.5 million, an increase of $15.0 million from the linked quarter and an increase of $30.0 million from the prior-year period. The increase from the linked quarter was primarily due to higher loan interest income as a result of increased average rates and higher average balances. This was partially offset by lower interest income from securities due to decreased average balances and increased deposit interest expense driven by average rates on public fund deposits. The increase in net interest income from the prior-year period was mainly due to an increase in interest income from loans and securities, which was a result of higher average balances, partially related to the Bank of Commerce Holdings acquisition. For additional information regarding net interest income, see the "Net Interest Margin" section and the "Average Balances and Rates" tables.

Provision for Credit Losses

Columbia recorded a $5.3 million provision for credit losses for the third quarter of 2022 compared to a $2.1 million provision for the linked quarter and no provision for the comparable quarter in 2021. The provision for credit losses was mainly due to loan growth, but also was impacted by a less favorable economic forecast.

Andy McDonald, Columbia's Executive Vice President and Chief Credit Officer, stated, "Strong loan growth resulted in modest provision expense during the quarter. We remain vigilant for economic challenges, which to date have been mitigated by strong credit quality metrics across the portfolio."

Noninterest Income

Noninterest income was $26.6 million for the third quarter of 2022, an increase of $1.6 million from the linked quarter and an increase of $2.7 million from the third quarter of 2021. The linked quarter increase was primarily due to a $3.7 million gain from the sale-leaseback of owned real estate. The gain was partially offset by decreased loan revenue, principally as a result of lower mortgage banking revenue and loan-related fees. Overall mortgage production declined as a result of the higher rate environment. The increase in noninterest income during the third quarter of 2022 compared to the same quarter in 2021 was mainly due to the previously noted sale-leaseback gain partially offset by decreased mortgage banking revenue.

Noninterest Expense

Total noninterest expense for the third quarter of 2022 was $101.4 million, an increase of $6.1 million compared to the second quarter of 2022. Total merger-related expenses for the quarter were $3.2 million, which compares to the linked quarter of $3.9 million. The largest contributor to the increase in noninterest expense was related to compensation and employee benefits driven by higher incentive expense. In addition, there was increased net loan expense and data processing and software expense during the quarter. Compared to the third quarter of 2021, noninterest expense increased $11.4 million, mostly attributable to an increase in compensation and employee benefits. This increase was primarily due to our acquisition of Bank of Commerce Holdings in the fourth quarter of 2021. Increased merger-related expenses also contributed to the increase from the prior-year period.

The provision for credit losses on unfunded loan commitments, a component of other noninterest expense, for the periods indicated are as follows:

	Three Months Ended			Nine Months Ended
	September 30,	June 30,	September 30,	September 30,	September 30,
	2022	2022	2021	2022	2021

Provision (recapture) for credit losses on unfunded loan commitments	$ (500)	$ —	$ 500	$ —	$ 2,200

Net Interest Margin

Columbia's net interest margin (tax equivalent) for the third quarter of 2022 was 3.47%, an increase of 31 basis points from the linked quarter and an increase of 30 basis points from the prior-year period. The increase in the net interest margin (tax equivalent) compared to the linked quarter and prior-year period was predominantly driven by higher average loan rates and a stronger earning assets mix. The average cost of total deposits for the quarter was 10 basis points compared to 5 basis points for the linked quarter. The increase was predominantly related to higher rates associated with public funds deposits. For additional information regarding net interest margin, see the "Average Balances and Rates" tables.

Columbia's operating net interest margin (tax equivalent)[1] was 3.50% for the third quarter of 2022, an increase of 27 basis points from the linked quarter and an increase of 34 basis points from the prior-year period. The increase in the operating net interest margin for the third quarter of 2022 compared to the linked quarter and the prior-year period were both due to higher average loan rates and a stronger earning assets mix.

Aaron James Deer, Columbia's Executive Vice President and Chief Financial Officer, said, "Our margin widened significantly during the quarter from the impact of rising market rates on strong loan production, existing loans coming off their floors and an improvement in the funding mix with half of our deposit base in noninterest-bearing accounts." He continued, "Our industry-leading deposit mix makes for a low deposit beta and should support further margin expansion."

Asset Quality

At September 30, 2022, nonperforming assets to total assets decreased to 0.07% compared to 0.08% at June 30, 2022. Total nonperforming assets decreased $3.5 million from the linked quarter, primarily due to decreases in commercial business and agriculture nonaccrual loans, partially offset by an increase in commercial real estate nonaccrual loans.

The following table sets forth information regarding nonaccrual loans and total nonperforming assets:

Organizational Update

Umpqua Merger

Integration planning related to the combination with Umpqua Holdings Corporation, which shareholders of both companies overwhelmingly approved in January, continues to move forward despite the extensive regulatory approval process currently overshadowing new merger and acquisition activity in the banking industry. "Once regulatory approval is received, we anticipate the deal to close very quickly due to the comprehensive preparation of our cross-company integration teams," said Clint Stein. He continued, "I am confident that the new company will build on our existing momentum and immediately impact banking throughout the west."

results of operations following strategic expansion, including the impact of acquired loans on our earnings, could differ from expectations;

increased competition among financial institutions and nontraditional providers of financial services;
continued consolidation in the financial services industry resulting in the creation of larger financial institutions that have greater resources could change the competitive landscape;

Non-GAAP Financial Measures

The Company considers its operating net interest margin (tax equivalent) and operating efficiency ratios to be useful measurements as they more closely reflect the ongoing operating performance of the Company. Despite the usefulness of the operating net interest margin (tax equivalent) and operating efficiency ratio to the Company, there are no standardized definitions for these metrics. As a result, the Company's calculations may not be comparable with those of other organizations. The Company encourages readers to consider its consolidated financial statements in their entirety and not to rely on any single financial measure.

The Company considers its ratio of allowance for credit losses to period-end loans, excluding PPP loans, to be a useful measurement in evaluating the adequacy of the amount of allowance for credit losses to loans of the Company, as PPP loans are guaranteed by the U.S. Small Business Administration and thus do not require the same amount of reserve for credit losses as do other loans. Despite the usefulness of this ratio to the Company, there is not a standardized definition for it. As a result, the Company's calculation may not always be comparable with those of other organizations. The Company encourages readers to consider its consolidated financial statements in their entirety and not to rely on any single financial measure.

Non-GAAP Financial Measures - Continued

The Company also considers its return on average tangible common equity ratio to be a useful measurement as it evaluates the Company's ongoing ability to generate returns for its common shareholders. By removing the impact of intangible assets and their related amortization and tax effects, the performance of the business can be evaluated, whether acquired or developed internally. Despite the usefulness of this ratio to the Company, there is not a standardized definition for it.
