CEO Comments

Chairman, President, and Chief Executive Officer Randy Newman said, “We are proud to report record quarterly net income of $17.7 million. Despite the uncertain economic environment and ongoing pandemic, our diversified business model demonstrates its value to stockholders as we delivered incredible financial performance throughout 2020. Our “One Alerus” approach to serving clients holistically through advisors and digitally through technology resulted in record levels of mortgage originations and expansions of relationships across our lines of business.

We believe we continue to be agile in our response to the novel coronavirus, or COVID-19 pandemic, by focusing on the health and well-being of our team members and communities, and helping clients during a difficult economic environment. The strength and stability of our balance sheet uniquely positioned our Company to perform well in challenging economic environments. We have a diversified loan portfolio, strong credit quality metrics, and robust levels of loan loss reserves at 1.83% of total loans, excluding Paycheck Protection Program, or PPP, loans. These balance sheet attributes, supported by a diversified business model which generates high levels of revenue despite the low rate environment is proving to be resilient in challenging and uncertain times.

Results of Operations

Net Interest Income

Net interest income for the third quarter of 2020 was $21.8 million, an increase of $1.7 million, or 8.3%, from $20.1 million for the second quarter of 2020. The increase was primarily driven by a decrease of $875 thousand in interest expense on deposits, an increase of $590 thousand in interest income from loans, and a $207 thousand increase in interest income from investment securities. The decrease in interest expense on deposits was primarily a result of a 25 basis point decrease in the cost of interest-bearing deposits, partially offset by a $119.6 million increase in average interest-bearing deposit balances. The increase in interest income from loans was primarily driven by a $74.3 million increase in average balance of PPP loans offset by a 4 basis point decrease in average yield. Interest and fees recognized on PPP loans totaled $3.2 million in the third quarter, an increase of $1.1 million from the second quarter. The increase in interest income from investment securities was primarily a result of a $74.5 million increase in average balances partially offset by a 21 basis point decrease in the average yield.

Compared to the third quarter of 2019, net interest income for the third quarter of 2020 increased $3.1 million, or 16.5%, primarily due to a $2.4 million decrease in interest expense and a $664 thousand increase in interest income. The decrease in interest expense was primarily due to an 84 basis point decrease in the average rate paid on interest-bearing liabilities. The increase in interest income was primarily due to a $674 thousand increase in interest income from investment securities driven by a $186.1 million increase in average balances partially offset by a 39 basis point decrease in the average yield.

Net Interest Margin (Tax-Equivalent)

Net interest margin (tax-equivalent), a non-GAAP financial measure, increased to 3.17% for the third quarter of 2020, compared with 3.14% for the second quarter of 2020. The increase in net interest margin was primarily due to a 26 basis point decrease in the average rate on total interest-bearing liabilities partially offset by a 14 basis point decrease in the average earning asset yield. The decrease in the average rate on total interest-bearing liabilities was primarily due to a 35 basis point decrease in the average rate on money market and savings deposits and a 32 basis point decrease in the average rate on time deposits. The decrease in average earning asset yield was due to the continued low interest rate environment and a change in balance sheet mix.

Compared to the third quarter of 2019, net interest margin (tax-equivalent) for the third quarter of 2020 decreased 52 basis points from 3.69%. This decrease was the combined result of sustained lower interest rates and balance sheet mix. The average yield

on interest earning assets decreased 112 basis points on an average balance increase of $727.6 million, or 36.1%. The average rate paid on interest-bearing liabilities decreased 84 basis points on an average balance increase of $407.9 million, or 29.0%.

Noninterest Income

Noninterest income for the third quarter of 2020 was $45.3 million, a $7.0 million, or 18.4%, increase from the second quarter of 2020. The increase was primarily driven by a $4.7 million increase in mortgage banking revenue, a $1.4 million increase in retirement and benefit services revenue, and a $374 thousand increase in wealth management revenue. The increase in mortgage banking revenue was primarily due to an $80.0 million increase in mortgage originations along with a 38 basis point increase in the gain on sale margin. The increase in retirement and benefit services revenue was primarily due to a $712 thousand increase in asset based revenue as a result of an increase in the average balance of assets under administration/management. In addition, the second quarter of 2020 included a downward adjustment to revenue sharing of $660 thousand.

Noninterest income for the third quarter of 2020 increased $15.7 million, or 53.0%, from $29.6 million in the third quarter of 2019. Mortgage banking revenue increased $14.1 million as mortgage originations increased from $313.5 million in the third quarter of 2019 to $511.6 million in the third quarter of 2020, and the gain on sale margin increased 75 basis points. In addition, the unrealized gain from the change in fair value of secondary market derivatives increased $5.2 million. Gains on investment securities were $1.4 million during the third quarter of 2020, compared to $48 thousand during the third quarter of 2019.

Noninterest Expense

Noninterest expense for the third quarter of 2020 was $40.2 million, an increase of $480 thousand, or 1.2%, compared to the second quarter of 2020. The increase was due to increases of $1.5 million in compensation expense, $380 thousand in marketing and business development expense and $286 thousand in employee taxes and benefits, partially offset by decreases of $968 thousand in other noninterest expense and $428 thousand in supplies and postage expenses. The increase in compensation expense was primarily driven by an increase in mortgage originations. Marketing and business development expense increased due to seasonally higher advertising expenses. Other noninterest expense decreased primarily due to a $990 thousand decrease in the provision for unused commitments. Supplies and postage expenses decreased due to the transition from paper statements to E-statements for the retirement and benefit services segment.

Compared to the third quarter of 2019, noninterest expense for the third quarter of 2020 increased $2.9 million, or 7.7%, from $37.3 million. The increase was attributable to increases of $2.7 million in compensation expense, $480 thousand in mortgage and lending expense, and $433 thousand in employee taxes and benefits, partially offset by decreases of $409 thousand in travel expense and $384 thousand in supplies and postage expense. The increases in compensation expense and mortgage and lending expense were primarily the result of higher mortgage originations.

Financial Condition

Total assets were $2.9 billion as of September 30, 2020, an increase of $541.9 million, or 23.0%, from December 31, 2019. The increase in total assets included increases of $337.1 million in loans, $185.1 million in available-for-sale investment securities, $64.5 million in loans held for sale, and $15.3 million in other assets.

Loans

Total loans were $2.06 billion as of September 30, 2020, an increase of $337.1 million, or 19.6%, from December 31, 2019. The increase was primarily due to increases of $309.9 million in commercial and industrial loans and $40.5 million in our commercial real estate loan portfolio, partially offset by a $20.1 million decrease in our consumer loan portfolio. The increase in commercial and industrial loans was due to an increase of $348.9 million in net PPP loans, offset by a 7.64% decrease in operating line utilization, or a $64.6 million decrease in funded balances.

For the third quarter of 2020, we had net recoveries of $581 thousand compared to net charge-offs of $3.3 million for the second quarter of 2020 and $240 thousand of net recoveries for the third quarter of 2019.

The provision for loan losses for the third quarter of 2020 was $3.5 million, which was the same amount as the second quarter of 2020 and an increase of $2.0 million from the third quarter of 2019. The increase in provision expense was due to allocations of reserves for the economic uncertainties related to COVID-19, which increased the allowance for loan losses balance by $7.4 million to $31.3 million at September 30, 2020, a 31.0% increase from December 31, 2019.

The ratio of nonperforming loans to total loans at September 30, 2020 was 0.23%, and if PPP loans were excluded, this ratio would have been 0.28%. Nonperforming assets as a percentage of total assets was 0.17% at September 30, 2020. Excluding PPP loans, nonperforming assets as a percentage of total assets would have been 0.19% at September 30, 2020.

As of September 30, 2020, we had entered into principal and interest deferrals of 552 loans representing $151.4 million in principal balances, since the beginning of the pandemic. Of those loans, 27 loans with a total outstanding principal balance of $16.9 million, have been granted second deferrals, 56 loans with a total outstanding principal balance of $12.0 million remain on the first deferral and the remaining loans have been returned to a normal payment status. All of these loan modifications were accounted for in accordance with the Interagency Statement on Loan Modifications and Reporting for Financial Institutions as issued on April 7, 2020, or have been evaluated under existing accounting policies, and are not considered troubled debt restructurings.

Capital

Total stockholders’ equity was $322.0 million as of September 30, 2020, an increase of $36.3 million from December 31, 2019. The tangible book value per common share increased to $16.31 as of September 30, 2020, from $14.08 as of December 31, 2019. Tangible common equity to tangible assets, a non-GAAP financial measure, decreased to 9.78% as of September 30, 2020, from 10.38% as of December 31, 2019. Tangible common equity to tangible assets would have been 11.14% as of September 30, 2020, if PPP loans were excluded.

Non-GAAP Financial Measures

Some of the financial measures included in this press release are not measures of financial performance recognized by U.S. Generally Accepted Accounting Principles, or GAAP. These non-GAAP financial measures include the ratio of tangible common equity to tangible assets, tangible common equity per share, return on average tangible common equity, net interest margin (tax-equivalent), and the efficiency ratio. Management uses these non-GAAP financial measures in its analysis of its performance, and believes financial analysts and investors frequently use these measures, and other similar measures, to evaluate capital adequacy. Reconciliations of non-GAAP disclosures used in this press release to the comparable GAAP measures are provided in the accompanying tables. Management, banking regulators, many financial analysts and other investors use these measures in conjunction with more traditional bank capital ratios to compare the capital adequacy of banking organizations with significant amounts of goodwill or other intangible assets, which typically stem from the use of the purchase accounting method of accounting for mergers and acquisitions.

These non-GAAP financial measures should not be considered in isolation or as a substitute for total stockholders’ equity, total assets, book value per share, return on average assets, return on average equity, or any other measure calculated in accordance with GAAP. Moreover, the manner in which we calculate these non-GAAP financial measures may differ from that of other companies reporting measures with similar names.

Forward-Looking Statements

This press release contains “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements include, without limitation, statements concerning plans, estimates, calculations, forecasts and projections with respect to the anticipated future performance of Alerus Financial Corporation. These statements are often, but not always, identified by words such as “may”, “might”, “should”, “could”, “predict”, “potential”,

“believe”, “expect”, “continue”, “will”, “anticipate”, “seek”, “estimate”, “intend”, “plan”, “projection”, “would”, “annualized”, “target” and “outlook”, or the negative version of those words or other comparable words of a future or forward-looking nature. Examples of forward-looking statements include, among others, statements we make regarding our projected growth, anticipated future financial performance, financial condition, credit quality, management’s long-term performance goals and the future plans and prospects of Alerus Financial Corporation.

Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions.

INVESTOR PRESENTATION OCTOBER 2020 Alerus

1 Forward-Looking Statements This presentation contains “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements include, without limitation, statements concerning plans, estimates, calculations, forecasts and projections with respect to the anticipated future performance of Alerus Financial Corporation. These statements are often, but not always, identified by words such as “may”, “might”, “should”, “could”, “predict”, “potential”, “believe”, “expect”, “continue”, “will”, “anticipate”, “seek”, “estimate”, “intend”, “plan”, “projection”, “would”, “annualized”, “target” and “outlook”, or the negative version of those words or other comparable words of a future or forward-looking nature. Examples of forward-looking statements include, among others, statements we make regarding our projected growth, anticipated future financial performance, financial condition, credit quality, management’s long-term performance goals and the future plans and prospects of Alerus Financial Corporation. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions.
