TACOMA, Washington, April 29, 2021 -- 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 first quarter 2021 earnings, “The momentum gained by our bankers at the end of 2020 accelerated during the quarter, resulting in record first-quarter, non-PPP loan production, exceptional deposit inflows, and record performance for the financial services group. Creating this momentum was intentional. Throughout the pandemic we remained forward-looking and focused on keeping our operations open safely while supporting the unique needs of both existing and new clients.”
Mr. Stein continued, “I cannot be more proud of our team’s efforts. Every one of our employees has helped our clients and communities weather the difficulties of an unprecedented year. During the quarter, we handled a higher number of PPP loan applications in the second round than we did in the first round, supporting existing and gaining new clients, and we handled the forgiveness process for first round PPP clients. Those not directly involved in the PPP program focused on growing our business. As the pandemic eases and communities fully reopen, we are well-positioned to take advantage of new opportunities.”

Balance Sheet
Total assets at March 31, 2021 were $17.34 billion, an increase of $750.3 million from the linked quarter. Loans were $9.68 billion, up $248.7 million from December 31, 2020 as loan originations of $894.6 million were partially offset by loan payments and a decrease in loan utilization. Total Paycheck Protection Program (“PPP”) loans increased from $651.6 million at December 31, 2020 to $894.1 million at March 31, 2021, which includes $399.3 million from the first round of PPP loans from 2020 and $494.8 million from the more recent round of PPP loans in 2021. Interest-earning deposits with banks were $706.4 million, an increase of $271.5 million from the linked quarter. Debt securities available for sale were $5.50 billion at March 31, 2021, an increase of $286.2 million from $5.21 billion at December 31, 2020 as a result of purchases during the quarter partially offset by principal pay downs and a decline in unrealized gains. Total deposits at March 31, 2021 were $14.77 billion, an increase of $897.6 million from December 31, 2020 largely due to an increase in demand and other noninterest-bearing deposits. The deposit mix remained fairly consistent from December 31, 2020 with 50% noninterest-bearing and 50% interest-bearing.
Income Statement
Net Interest Income
Net interest income for the first quarter of 2021 was $124.0 million, a decrease of $7.1 million from the linked quarter and an increase of $1.6 million from the prior-year period. The decrease from the linked quarter is primarily due to interest income from loans, which decreased mainly due to lower average rates. In addition, the linked quarter included a $1.7 million recovery of interest related to a nonaccrual loan that paid off during the fourth quarter of 2020. The increase in net interest income from the prior year period was primarily a result of a reduction in interest expense on Federal Home Loan Bank (“FHLB”) advances and deposits, partially offset by a decline in interest income on loans. The decrease in interest expense was due to lower average balances of FHLB advances and lower rates on deposits. The decline in interest income from loans was mainly due to lower average rates. 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 recorded a net provision recovery for credit losses for the first quarter of 2021 of $800 thousand compared to a net provision recovery of $4.7 million for the linked quarter and a net provision of $41.5 million for the comparable quarter in 2020.

Andy McDonald, Columbia's Executive Vice President and Chief Credit Officer, commented, “Overall credit metrics for the quarter were relatively stable. There were no material changes in our nonaccruals or nonperforming assets or within the loan portfolio, and we saw a modest release from the provision stemming from the improving economic forecast. We are seeing positive signs that the economy is recovering from the pandemic, and our focus with our clients has shifted to their longer-term cash flow needs.”
Noninterest Income
Noninterest income was $23.2 million for the first quarter of 2021, a decrease of $396 thousand from the linked quarter and an increase of $2.0 million from the first quarter of 2020. The decrease compared to the linked quarter was principally due to lower loan revenue. The increase in noninterest income during the first quarter of 2021 compared to the same quarter in 2020 was principally due to an increase in loan revenue partially offset by a decrease in deposit account and treasury management fees. The increase in loan revenue compared to the first quarter of 2020 was due to mortgage banking revenue, which increased $3.4 million due to higher loan volume and increased premium per loan on sold loans. The decrease in deposit account and treasury management fees was driven by a decrease in overdraft fees of $988 thousand compared to the same quarter in 2020 due to an overall decrease in the number of transactions amidst the pandemic as well as clients generally carrying higher cash balances in their deposit accounts.
Chris Merrywell, Columbia’s Executive Vice President and Chief Operating Officer, stated, “Our bankers have been busy delivering products and services that our clients value as we exit the pandemic. Our approach of staying open while maintaining the health and safety of our clients and our employees during the past year has resulted in expanded relationships and solid fee income. Mortgage volumes and sale executions continued to be very strong during the quarter, and our investment professional teams’ performance was the best in our history.”
Noninterest Expense
Total noninterest expense for the first quarter of 2021 was $83.6 million, a decrease of $741 thousand compared to the fourth quarter of 2020, principally due to a decrease in compensation and employee benefits expense partially offset by an increase in data processing and software expense. The decrease in compensation and employee benefits expense was mostly attributable to labor costs related to the origination of PPP loans. These labor costs are capitalized and amortized as a reduction to interest income over the life of the loan. The increase in data processing and software expense was driven by additional data processing expense associated with PPP loans.
3

Compared to the first quarter of 2020, noninterest expense decreased $712 thousand, principally due to a decrease in compensation and employee benefits expense partially offset by increases in data processing and software expense and regulatory premiums. The decrease in compensation and employee benefits expense and the increase in data processing and software expense are due to the items described in the preceding paragraph. The increase in regulatory premiums was the result of the Bank utilizing a portion of its Small Bank Assessment Credit during the first quarter of 2020 to pay for Federal Deposit Insurance Corporation (“FDIC”) deposit insurance premiums. The final portion of the credit was utilized during the second quarter of 2020.
The provision for unfunded loan commitments, a component of other noninterest expense, for the periods indicated are as follows:

Provision (recapture) for unfunded loan commitments |  | $ | 1,500 |  |  | $ | (1,300) |  |  | $ | 1,000 |  |  |  |  |

Net Interest Margin
Columbia’s net interest margin (tax equivalent) for the first quarter of 2021 was 3.31%, a decrease of 21 basis points and 69 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 was due to a decrease in interest income from loans as result of the lower rate environment, as well as the linked quarter including additional interest income related to a nonaccrual loan that was paid off during the quarter. Notably, the average cost of total deposits for the quarter was 4 basis points, a decrease of 1 basis point from the fourth quarter of 2020. The decrease in the net interest margin (tax equivalent) compared to the 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. For additional information regarding net interest margin, see the “Average Balances and Rates” tables.
Columbia’s operating net interest margin (tax equivalent)1 was 3.30% for the first quarter of 2021, which decreased 21 basis points compared to the linked quarter and decreased 72 basis points compared to the prior-year period. The decrease in the operating net interest margin for the first quarter of 2021 compared to the linked quarter and the decrease compared to the prior-year period were due to the items noted in the preceding paragraph.
1 Operating net interest margin (tax equivalent) is a non-GAAP financial measure. See the section titled “Non-GAAP Financial Measures” in this earnings release for the reconciliation of operating net interest margin (tax equivalent) to net interest margin.

The following table highlights the yield on our PPP loans for the periods indicated:

|  | Three Months Ended |  |
|  | March 31, 2021 |  | December 31, 2020 |  |
Paycheck Protection Program loans |  | (dollars in thousands)
Interest income |  | $ | 9,097 |  |  | $ | 9,218 |  |  |
Average balance |  | $ | 828,051 |  |  | $ | 822,970 |  |  |
Yield |  | 4.46 | % |  | 4.46 | % |  |

Aaron James Deer, Columbia’s Executive Vice President and Chief Financial Officer, stated, “While we are very encouraged by the strengthening economic outlook and steepening yield curve, our net interest margin may remain under modest pressure over the near term with some volatility stemming from PPP forgiveness. Longer term, we expect the margin to stabilize and ultimately expand as the rate environment improves and earning asset growth shifts back toward loans.”
Asset Quality
At March 31, 2021, nonperforming assets to total assets decreased to 0.20% compared to 0.21% at December 31, 2020. Total nonperforming assets decreased $1.3 million from the linked quar ter, primarily due to a decrease in agriculture nonaccrual loans.

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.
The following tables reconcile the Company’s calculation of the operating net interest margin (tax equivalent) and operating efficiency ratio:

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.
The following table reconciles the Company’s calculation of the pre-tax, pre-provision income:

The Company considers its tangible common equity ratio and tangible book value per share ratio to be useful measurements in evaluating the capital adequacy of the Company as they provide a method to assess management’s success in utilizing our tangible capital. Despite the usefulness of these ratios to the Company, there is not a standardized definition for them. 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. The Company encourages readers to consider its consolidated financial statements in their entirety and not to rely on any single financial measure.
