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 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 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 forward-looking statements include, among others, the following: interest rate risk, including the effects of recent and potential additional rate increases by the Federal Reserve; our ability to successfully manage credit risk and maintain an adequate level of allowance for credit losses; new or revised accounting standards; business and economic conditions generally and in the financial services industry, nationally and within our market areas, including continued rising rates of inflation and possible recession; the effects of recent developments and events in the financial services industry, including the large-scale deposit withdrawals over a short-period of time at Silicon Valley Bank, Signature Bank and First Republic Bank that resulted in the failure of those institutions; 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, including the integration of Metro Phoenix Bank which we acquired in 2022; 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 or our third-party vendors’ information security controls or cybersecurity-related incidents, including as a result of sophisticated attacks using artificial intelligence and similar tools; 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, including digital asset service providers; our ability to successfully manage liquidity risk, including our need to access higher cost sources of funds such as fed funds purchased and short-term borrowings; the concentration of large deposits from certain clients, who have balances above current Federal Deposit Insurance Corporation (“FDIC”) insurance limits; 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, including the acquisition of Metro Phoenix Bank; the extensive regulatory framework that applies to us; the impact of recent and future legislative and regulatory changes, including in response to the recent failures of Silicon Valley Bank, Signature Bank and First Republic Bank in 2023; fluctuations in the values of the securities held in our securities portfolio, including as a result of changes in interest rates; governmental monetary, trade and fiscal policies; risks related to climate change and the negative impact it may have on our customers and their businesses; severe weather, natural disasters, widespread disease or pandemics; acts of war or terrorism, including the Israeli-Palestinian conflict and the Russian invasion of Ukraine, or other adverse external events; any material weaknesses in our internal control over financial reporting; 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; potential changes in federal policy and at regulatory agencies as a result of the upcoming 2024 presidential election; talent and labor shortages and employee turnover; 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.

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.
