TACOMA, Washington, October 29, 2020 -- Clint Stein, President and Chief Executive Officer of Columbia Banking System, Inc. and Columbia Bank (NASDAQ: COLB) (“Columbia”), said today upon the release of Columbia’s third quarter 2020 earnings, “I’m extremely proud of our bankers’ commitment to our clients and communities as we push through the lingering effects of COVID-19. We continued to experience strong deposit growth during the quarter, helped by our normal seasonal inflows. Loan growth was challenged by soft borrower demand coupled with lower line utilization. Even so, earnings were supplemented as more excess liquidity was deployed into investment securities.” Mr. Stein continued, “In addition, solid performance in our mortgage lending group and improved card transaction volumes, boosted our noninterest income.”

Balance Sheet
Total assets at September 30, 2020 were $16.23 billion, an increase of $312.5 million from the linked quarter. Loans were $9.69 billion, down $83.0 million from June 30, 2020 as loan originations of $279.0 million were more than offset by loan payments and a decrease in loan utilization. Included in the loan originations for the quarter were $9.4 million of loans originated under the Paycheck Protection Program (“PPP”). Interest-earning deposits with banks were $736.4 million, a decrease of $143.8 million from the linked quarter. Debt securities available for sale were $4.28 billion at September 30, 2020, an increase of $587.9 million from $3.69 billion at June 30, 2020. Total deposits at September 30, 2020 were $13.60 billion, an increase of $468.8 million from June 30, 2020 largely due to an increase of $291.2 million in interest-bearing deposits. The deposit mix remained fairly consistent from June 30, 2020 with 51% noninterest-bearing and 49% interest-bearing. The average cost of total deposits for the quarter was 6 basis points, a decrease of 1 basis point from the second quarter of 2020. For additional information regarding this calculation, see the “Net Interest Margin” section.
Chris Merrywell, Columbia’s Executive Vice President and Chief Operating Officer, stated, “As the “shelter-in-place” orders were relaxed during the quarter, our small business clients returned to a new normal for their business operations. Encouragingly, despite the ongoing challenges, most business owners have an optimistic outlook, which was reflected in an uptick in loan origination activity during the last few months.”

Income Statement
Net Interest Income
Net interest income for the third quarter of 2020 was $124.7 million, an increase of $2.9 million and $2.3 million from the linked-quarter and the prior-year period, respectively. The increase in net interest income from the linked quarter was primarily due to lower interest expense on Federal Home Loan Bank (“FHLB”) advances as a result of a $352.9 million decrease in the average balance of FHLB advances during the third quarter of 2020. In addition, an increase in the average balance of taxable securities, partially offset by a decline in rates, also contributed to the rise in net interest income compared to the linked quarter. Net interest income compared to the prior-year period increased primarily as a result of a reduction in interest expense on deposits and FHLB advances partially offset by a decline in interest income on interest-earning assets. The reduction in deposit interest expense was due to the lower interest rate environment while the reduction in interest expense on FHLB advances was principally due to lower average balances of advances. Interest income from securities increased principally due to higher average balances. Partially offsetting these favorable changes to net interest income was a decline in loan interest income due to the lower rate environment. For additional information regarding net interest income, see the “Net Interest Margin” section and the “Average Balances and Rates” tables.
Provision for Credit Losses
The Bank’s provision for credit losses for the third quarter of 2020 was $7.4 million compared to $33.5 million for the linked quarter and $299 thousand for the comparable quarter in 2019. The provision for credit losses for the third quarter of 2020 compared to the linked quarter declined due to an improved economic forecast but remained elevated relative to the prior year principally as a result of COVID-19 and the 2020 downturn in the national and global economies. For more information, please see the “COVID-19 Update” section of this earnings release.
Andy McDonald, Columbia’s Executive Vice President and Chief Credit Officer, commented, “For the quarter, our credit metrics remained very stable by almost all measures. We are pleased that our thesis on deferrals in the professional healthcare space is playing out as we expected. In addition, the provision for credit losses for the quarter was modest compared to the prior two quarters reflecting our efforts earlier this year to quickly address the challenges the pandemic presented. In this regard, we remain cautious as we head into the winter season and gain distance from the positive effects of earlier fiscal stimulus and loan deferrals.”

Noninterest Income
Noninterest income was $22.5 million for the third quarter of 2020, a decrease of $14.8 million from the linked quarter and $5.6 million from the third quarter of 2019. The decrease compared to the linked quarter was principally due to the sale of Visa Class B shares during the second quarter of 2020. The Bank sold 17,360 shares of Visa Class B restricted stock for a gain of $3.0 million and wrote up its remaining 77,683 Visa Class B restricted shares to fair value resulting in a gain of $13.4 million, for a total gain of $16.4 million. Partially offsetting this decrease in noninterest income was an increase in mortgage banking revenue during the third quarter of 2020 primarily due to a higher volume of mortgage loans originated and sold. The decrease in noninterest income during the third quarter of 2020 compared to the same quarter in 2019 was principally due to a $5.9 million gain from the sale-leaseback of owned real estate during the third quarter of 2019. In addition, treasury management and overdraft fees decreased by $993 thousand and $921 thousand, respectively, compared to the same quarter in 2019. The decrease in overdraft fees was due to an overall decrease in the number of transactions during this pandemic time period as well as clients generally carrying higher cash balances in their deposit accounts. Partially offsetting these decreases in noninterest income was an increase in mortgage banking revenue of $2.3 million compared to the prior year period for the same reason stated above for the linked-quarter comparison.
Noninterest Expense
Total noninterest expense for the third quarter of 2020 was $85.1 million, an increase of $4.3 million compared to the second quarter of 2020 principally due to higher compensation and benefits expense partially offset by decreases in other noninterest and data processing expenses. The increase in compensation and benefits expense was due to the large deferral of labor costs related to the origination of PPP loans during the second quarter of 2020. These costs are treated as a contra expense and reduced compensation and benefits expense. As the number of PPP loan originations declined during the third quarter of 2020 compared to the second quarter, the amount of deferred labor costs decreased. This increase in noninterest expense for the third quarter of 2020 was partially offset by a decrease in the provision for unfunded loan commitments of $2.0 million, which is a component of other noninterest expense. In addition, data processing expense decreased $944 thousand due to the decline in PPP loan origination activity compared to the linked quarter.
4


Compared to the third quarter of 2019, noninterest expense decreased $2.0 million principally due to legal and professional fees and advertising and promotion expenses partially offset by an increase in other noninterest expense. Legal and professional fees declined $2.7 million while advertising and promotion expenses decreased $1.1 million. Partially offsetting these decreases was a $1.2 million increase in the provision for unfunded loan commitments due to higher estimated loss rates and higher amounts of unfunded loan commitments compared to the same period in 2019.
The provision for unfunded loan commitments for the periods indicated are as follows:

Net Interest Margin
Columbia’s net interest margin (tax equivalent) for the third quarter of 2020 was 3.47%, a decrease of 17 basis points and 67 basis points from the linked-quarter and prior-year period, respectively. The decrease in the net interest margin (tax equivalent) compared to the linked-quarter and prior-year period was driven by higher average interest-earning deposits with banks at an average rate of 10 basis points as well as lower rates on the loan and securities portfolios.
Columbia’s operating net interest margin (tax equivalent)1 was 3.46% for the third quarter of 2020, which decreased 18 and 66 basis points compared to the linked-quarter and the prior-year period, respectively. The decreases in the operating net interest margin for the third quarter of 2020 compared to the linked-quarter and the prior-year period were due to the items noted in the preceding paragraph.

Aaron James Deer, Columbia’s Executive Vice President and Chief Financial Officer, stated, “The net interest margin remained under pressure during the quarter, as ultra-low interest rates and the flat yield curve continued to weigh on asset yields. Notwithstanding some upcoming benefit from PPP forgiveness, this margin pressure is likely to remain a headwind to net interest income given the current rate outlook.”
Asset Quality
At September 30, 2020, nonperforming assets to total assets decreased to 0.29% compared to 0.34% at June 30, 2020. Total nonperforming assets decreased $6.6 million from the linked quarter due to decreases in agriculture and commercial business nonaccrual loans.

Organizational Update
COVID-19 Update
We continue to monitor the spread of COVID-19 in our communities and adapt to changes in guidance from local healthcare officials. The measures we have taken to provide a safe environment for our team members and clients have been effective.
Branch lobbies across the footprint have remained open for standard business hours to serve clients throughout the quarter. The diligence of our team members and their commitment to the safety of their colleagues and clients has minimized the risk of spread in our facilities and helped us keep operating with minimal disruption.
Throughout the summer our leaders prepared to support team members with school-aged children returning to distanced learning programs. These adjustments have afforded many team members the support needed to help ease the pressures of distanced learning requirements. Responding to these temporary challenges with a variety of flexible options while upholding client service standards has also allowed us to retain existing talent.
Our participation in the Small Business Administration’s (“SBA”) Paycheck Protection Program has entered a new phase as clients began submitting requests for loan forgiveness. We began processing requests as soon as the SBA formally opened their portal. As of October 26th, we have taken over 1,400 applications and approved/submitted nearly 850 of those to the SBA for more than $220.0 million.
Northwest Wildfire Response
The devastating wildfires that swept across Washington and Oregon this summer resulted in significant damage to Northwest forests and neighboring communities. Even those communities spared the devastation of the fires were met with disruption related to weeks of poor air quality. To support recovery efforts, Columbia Bank has donated $25,000 to the Red Cross Northwest Wildfire Relief Fund. In addition, the employee led non-profit Columbia Cares will provide small grants to Northwest families and individuals who have been impacted by the wildfires.
“Our communities have demonstrated tremendous resilience in the face of great challenges this year,” noted Mr. Stein. “We are pleased to support the effort to recover and rebuild through the Red Cross fund and our employee-led Columbia Cares organization.”

Boise NeighborHub
Columbia opened its first retail location in downtown Boise, Idaho on September 28, 2020. The Boise NeighborHub combines client-focused technology and the elevated skill set of a banker with universal sales and support expertise. The opening marks the second location of the bank’s signature NeighborHub concept, which serves the broader community as a hub for educational seminars, local events and community functions in addition to traditional banking and financial services.
“We are delighted to announce the opening of our Boise NeighborHub,” said Chris Merrywell, Executive Vice President and Chief Operating Officer. “Combined with our existing commercial and healthcare banking teams, the new location allows us to offer Boise clients access to our full suite of business, consumer and wealth management solutions.”
Cash Dividend Announcement
Columbia will pay a regular cash dividend of $0.28 per common share on November 25, 2020 to shareholders of record as of the close of business on November 11, 2020.
Common Stock Share Repurchase Program
Columbia Banking System’s board of directors has authorized a share repurchase program which permits the repurchase of up to 3.5 million shares, or approximately 5%, of the Company’s outstanding common stock. Repurchases will be made at management’s discretion. “Columbia is committed to driving long term shareholder value and we believe that having a share repurchase program as part of our capital strategy increases the options we have available to achieve this goal,” said Clint Stein, President and Chief Executive Officer.
Interest Rate Collar
Subsequent to quarter end, in October 2020, we terminated our $500 million notional interest rate collar. This termination locked in the $34.9 million value of the interest rate collar and this amount, net of deferred income taxes, will be amortized into interest income through February 2024.

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 them. As a result, the Company’s calculations may not be comparable with 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 considers its pre-tax, pre-provision income to be a useful measurement in evaluating the earnings of the Company as it provides a method to assess income. Despite the usefulness of this measure to the Company, there is not a standardized definition for it. As a result, the Company’s calculation may not always be comparable with 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 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 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 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. As a result, the Company’s calculation may not always be comparable with other organizations.
