ALERUS FINANCIAL CORPORATION REPORTS

THIRD QUARTER 2022 NET INCOME OF $9.6 MILLION

MINNEAPOLIS, MN (October 26, 2022) – Alerus Financial Corporation (Nasdaq: ALRS) reported net income of $9.6 million for the third quarter of 2022, or $0.47 per diluted common share, compared to net income of $9.3 million, or $0.52 per diluted common share, for the second quarter of 2022, and net income of $13.1 million, or $0.74 per diluted common share, for the third quarter of 2021. Excluding the acquisition of Metro Phoenix Bank, earnings per diluted common share were $0.54 for the third quarter of 2022.

CEO Comments

President and Chief Executive Officer Katie Lorenson said, “We ended the quarter with net income of $9.6 million; this included $1.8 million of merger expenses as we closed and converted the Metro Phoenix Bank acquisition during the quarter. The seamless integration of Metro Phoenix Bank marks a historic milestone as the Company’s twenty-fifth acquisition.

Our financial results were highlighted by strong loan growth during the quarter, driven by the addition of new team members and expansion of existing client relationships. During the last several years we have invested further in our credit talent and infrastructure. We have improved our credit policies and deepened our credit risk management practices in preparation for improved organic loan growth. The Company’s historic net charge-off ratio is 27 basis points, dating back over 25 years. Prudent credit underwriting and client selection continue to remain a key focus as we lend through the uncertainty of the current economic cycle.

We continue to position the Company strategically as the economic environment continues to evolve. We believe our diversified business model, with recurring revenue streams, strong capital levels, liquidity profile, and underwriting culture will continue to differentiate us from the rest of the industry. I know our team will respond to any challenge and I am proud of their constant dedication to serving our clients and communities, and for delivering positive results for our shareholders.”

Results of Operations

Net Interest Income

Net interest income for the third quarter of 2022 was $28.3 million, a $5.5 million, or 24.3%, increase from the second quarter of 2022. Net interest income increased $7.2 million, or 34.0%, from $21.1 million for the third quarter of 2021. The linked quarter increase was primarily driven by increases of $7.4 million in interest income from loans and a $591 thousand increase in other interest income, partially offset by increases of $1.2 million in interest expense related to short-term borrowings and $1.0 million in interest expense from deposits, the result of a rising interest rate environment and an increase in our short-term borrowings. The increases in loans and deposits were primarily the result of the Metro Phoenix Bank acquisition which included $270.4 million in loans and $353.7 million in deposits. Short-term borrowings increased primarily due to loan growth outpacing deposit growth.

Net interest margin (tax-equivalent), a non-GAAP financial measure, was 3.21% for the third quarter of 2022, a 23 basis point increase from 2.98% for the second quarter of 2022, and a 43 basis point increase from 2.78% in the third quarter of 2021. Excluding the acquisition of Metro Phoenix Bank, net interest margin was 3.04% for the third quarter of 2022, a 6 basis point increase from the second quarter of 2022, and a 26 basis point increase from the third quarter of 2021. The quarter over quarter increase was primarily driven by a 45 basis point increase in interest earning asset yields, partially offset by a 35 basis point increase in the rate paid on interest-bearing liabilities, the result of a rising interest rate environment. Additionally, we saw the average balance on interest-earning assets and interest-bearing liabilities increase, primarily due to the loans and deposits acquired from Metro Phoenix Bank.

Noninterest Income

Noninterest income for the third quarter of 2022 was $27.0 million, a $2.2 million, or 7.6%, decrease from the second quarter of 2022. The linked quarter decrease was primarily driven by decreases of $2.3 million in mortgage banking revenue and $696 thousand in wealth management revenue. Partially offsetting these decreases was a $304 thousand increase in retirement and benefit services revenue. The decrease in mortgage banking revenue was primarily driven by a $39.5 million, or 14.7%, decrease in mortgage originations as well as an 82 basis point decrease in the gain on sale margin. Wealth management revenue decreased primarily due to a $712.0 million decrease in assets under management, the result of an overall market value decrease.

2

Noninterest income for the third quarter of 2022 decreased $9.0 million, or 25.1%, from $36.0 million in the third quarter of 2021. The year over year decrease was primarily driven by decreases of $7.3 million in mortgage banking revenue, $1.4 million in retirement and benefit services revenue and $443 thousand in wealth management revenue. Mortgage banking revenue decreased primarily due to a $185.9 million, or 44.7%, decrease in mortgage originations and a 94 basis point decrease in the gain on sale margin. Retirement and benefit services revenue decreased primarily due to a decrease in asset-based fees from a $5.7 billion decrease in assets under administration/management. Wealth management revenue decreased primarily as a result of a $429.3 million decrease in assets under management, the result of declines in market values.

Noninterest Expense

Noninterest expense for the third quarter of 2022 was $42.8 million, a $2.8 million, or 7.0%, increase compared to the second quarter of 2022. The linked quarter increase was primarily driven by increases of $1.7 million in other noninterest expense and $880 thousand in professional fees and assessments expense. Partially offsetting these increases was a $708 thousand decrease in employee taxes and benefits expense. The increase in other noninterest expense was primarily driven by a $1.3 million increase in the provision for unused commitments. This provision expense was the result of new business generated within our real estate construction loans. Professional fees and assessments expense included $1.8 million in merger related expenses associated with the acquisition of Metro Phoenix Bank, an increase of $998 thousand from the prior quarter. Employee taxes and benefits decreased primarily due to a $328 thousand decrease in health insurance claims from the prior quarter.

Noninterest expense for the third quarter of 2022 increased $726 thousand, or 1.7%, from $42.0 million in the third quarter of 2021. The year over year increase in noninterest expense was primarily driven by increases of $1.7 million in other noninterest expense and $1.6 million in professional fees and assessments, partially offset by a $2.1 million decrease in compensation expense. Noninterest expense increased primarily as a result of an $841 thousand increase in the provision for unused commitments, the result of new business generated within our real estate construction loans. Professional fees and assessments increased primarily due to $1.8 million in merger related expenses associated with the acquisition of Metro Phoenix Bank. The year over year decrease in mortgage originations drove the overall decrease in compensation expense as compared to the third quarter of 2021.

Financial Condition

Total assets were $3.7 billion as of September 30, 2022, an increase of $298.6 million, or 8.8%, from December 31, 2021. The overall increase in total assets included an increase of $560.2 million in loans held for investment, partially offset by decreases of $188.1 million in cash and cash equivalents and $150.2 million in investment securities.

Loans

Total loans were $2.3 billion as of September 30, 2022, an increase of $560.2 million, or 31.9%, from December 31, 2021. This increase was primarily due to increases of $270.4 million in loans acquired from Metro Phoenix Bank and $289.8 million in organic loan growth. Excluding loans acquired from Metro Phoenix Bank, the increases in organic loan growth included increases of $119.5 million in residential real estate first mortgages, $91.9 million in commercial real estate loans, and $31.3 million in commercial and industrial loans, also excluding PPP loans, commercial and industrial loans increased $62.0 million.

(1) Includes PPP loans of $2.9 million at September 30, 2022, $6.9 million at June 30, 2022, $13.1 million at March 31, 2022, $33.6 million at December 31, 2021 and $103.5 million at September 30, 2021.

Deposits

Total deposits were $3.0 billion as of September 30, 2022, an increase of $41.3 million, or 1.4%, from December 31, 2021. Interest-bearing deposits increased $74.9 million, while noninterest-bearing deposits decreased $33.6 million in the third quarter of 2022. The increase in total deposits was primarily due to $353.7 million of deposits acquired from Metro Phoenix Bank. Excluding deposits acquired from Metro Phoenix Bank, deposits decreased $312.4 million, or 10.7%. The decrease was primarily driven by decreases of $129.8 million in noninterest-bearing deposits, $80.0 million in interest-bearing demand deposits, and $59.3 million in time deposits. Noninterest-bearing deposits decreased primarily due to a decrease in synergistic deposits. The decrease in interest-bearing demand deposits was the result of seasonally lower balances in public unit deposits. Time deposits decreased due to clients shifting balances to more liquid accounts. Synergistic deposits, which include deposits from our retirement and benefit services and wealth management segments as well as HSA deposits, decreased $35.5 million from December 31, 2021 primarily due to year-end seasonally higher temporary balances from retirement plan terminations.

Asset Quality

Total nonperforming assets were $6.2 million as of September 30, 2022, an increase of $3.1 million, or 101.4%, from December 31, 2021, primarily due to a residential real estate first mortgage client that is being individually evaluated for impairment. As of September 30, 2022, the allowance for loan losses was $31.0 million, or 1.34% of total loans, compared to $31.6 million, or 1.80% of total loans, as of December 31, 2021. Excluding Metro Phoenix Bank, the allowance for loan losses to total loans was 1.51% as of September 30, 2022.

For the third quarter of 2022, we had net charge-offs of $405 thousand compared to net charge-offs of $340 thousand for the second quarter of 2022 and $302 thousand of net recoveries for the third quarter of 2021.

There was no provision expense recorded for the three months ended September 30, 2022, no change compared to the three months ended June 30, 2022, and a $2.0 million increase as compared to the three months ended September 30, 2021. Although management saw increases in overall loan volume, based on the reduction of previous adjustments for pandemic related qualitative factors, management concluded no need for additional provision.

Capital

Total stockholders’ equity was $344.8 million as of September 30, 2022, a decrease of $14.6 million, or 4.1%, from December 31, 2021. The decrease in stockholders’ equity was primarily due to a $98.7 million decrease in accumulated other comprehensive loss, due to rising interest rates, which resulted in a lower fair value of our available-for-sale investment securities, partially offset by a $61.8 million increase in additional paid-in capital as a result of the Metro Phoenix Bank acquisition. Tangible book value per common share, a non-GAAP financial measure, decreased to $13.76 as of September 30, 2022, from $17.87 as of December 31, 2021. Tangible common equity to tangible assets, a non-GAAP financial measure, decreased to 7.59% as of September 30, 2022, from 9.21% as of December 31, 2021. Common equity tier 1 capital to risk weighted assets decreased to 13.63% as of September 30, 2022, from 14.65% as of December 31, 2021.

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 and financial performance. 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. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Our actual results and financial condition may differ materially from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements include, among others, the following: interest rate risks associated with our business, including the effects of recent and anticipated rate increases by the Federal Reserve; our ability to successfully manage credit risk and maintain an adequate level of allowance for loan losses; new or revised accounting standards, including as a result of the implementation of the new Current Expected Credit Loss Standard; business and economic conditions generally and in the financial services industry, nationally and within our market areas, including rising rates of inflation; the overall health of the local and national real estate market; concentrations within our loan portfolio; the level of nonperforming assets on our balance sheet; our ability to implement our organic and acquisition growth strategies; the impact of economic or market conditions on our fee-based services; our ability to continue to grow our retirement and benefit services business; our ability to continue to originate a sufficient volume of residential mortgages; the occurrence of fraudulent activity, breaches or failures of our information security controls or cybersecurity-related incidents; interruptions involving our information technology and telecommunications systems or third-party servicers; potential losses incurred in connection with mortgage loan repurchases; the composition of our executive management team and our ability to attract and retain key personnel; rapid technological change in the financial services industry; increased competition in the financial services industry from non-banks such as credit unions and Fintech companies; our ability to successfully manage liquidity risk, especially in light of recent excess liquidity at the Bank; the effectiveness of our risk management framework; the commencement and outcome of litigation and other legal proceedings and regulatory actions against us or to which we may become subject; potential impairment to the goodwill we recorded in connection with our past acquisitions; the extensive regulatory framework that applies to us; the impact of recent and future legislative and regulatory changes; fluctuations in the values of the securities held in our securities portfolio, including as a result of rising interest rates; governmental monetary, trade and fiscal policies; severe weather, natural disasters, widespread disease or pandemics, such as the COVID-19 global pandemic, the negative effects of the ongoing COVID-19 pandemic, including its effects on the economic environment, our clients, and our operations, including due to supply chain disruptions, as well as any changes to federal, state, or local government laws, regulations, or orders in response to the pandemic; acts of war or terrorism, including the Russian invasion of Ukraine, or other adverse external events; any material weaknesses in our internal control over financial reporting; developments and uncertainty related to the future use and availability of some reference rates, such as the London Interbank Offered Rate, as well as other alternative rates; changes to U.S. or state tax laws, regulations and guidance, including the new 1.0% excise tax on stock buybacks by publicly traded companies; talent and labor shortages and employee turnover; possible federal mask and vaccine mandates; our success at managing the risks involved in the foregoing items; and any other risks described in the “Risk Factors” sections of the reports filed by Alerus Financial Corporation with the Securities and Exchange Commission.

Any forward-looking statement made by us in this press release is based only on information currently available to us and speaks only as of the date on which it is made. We undertake no obligation to publicly update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise.
