Disclaimer 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 the Company. 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. 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 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 risk, including the effects of changes in interest rates; effects on the U.S. economy resulting from the implementation of policies proposed by the new presidential administration, including tariffs, mass deportations and tax regulations; fluctuations in the values of the securities held in our securities portfolio, including as the result of changes in interest rates; business and economic conditions generally and in the financial services industry, nationally and within our market area, including the level and impact of inflation and possible recession; the effects of developments and events in the financial services industry, including the large-scale deposit withdrawals over a short period of time that resulted in several bank failures; credit risk and risks from concentrations (by type of borrower, geographic area, collateral and industry) within the Company’s loan portfolio or large loans to certain borrowers (including CRE loans); the overall health of the local and national real estate market; our ability to successfully manage credit risk; our ability to maintain an adequate level of allowance for credit losses; new or revised accounting standards as may be adopted by state and federal regulatory agencies, the Financial Accounting Standards Board, Securities and Exchange Commission (the “SEC”) or Public Company Accounting Oversight Board; the concentration of large loans to certain borrowers; the concentration of large deposits from certain clients, including those who have balances above current Federal Deposit Insurance Corporation (“FDIC”) insurance limits; our ability to successfully manage liquidity risk, which may increase our dependence on non-core funding sources such as brokered deposits, and negatively impact our cost of funds; our ability to raise additional capital to implement our business plan; our ability to implement our growth strategy and manage costs effectively; the composition of our senior leadership team and our ability to attract and retain key personnel; talent and labor shortages and employee turnover; 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 or as a result of insider fraud; interruptions involving our information technology and telecommunications systems or third-party servicers; competition in the financial services industry, including from nonbank competitors such as credit unions, “fintech” companies and digital asset service providers; the effectiveness of our risk management framework; the commencement, cost and outcome of litigation and other legal proceedings and regulatory actions against us; the impact of recent and future legislative and regulatory changes, including in response to prior bank failures; risks related to climate change and the negative impact it may have on our customers and their businesses; the imposition of tariffs or other governmental policies impacting the value of products produced by our commercial borrowers; severe weather, natural disasters, wide spread disease or pandemics, acts of war or terrorism or other adverse external events, including ongoing conflicts in the Middle East and the Russian invasion of Ukraine; potential impairment to the goodwill the Company recorded in connection with acquisitions; risks associated with our acquisition of First Minnetonka City Bank (“FMCB”), including the possibility that the merger may be more difficult or expensive to integrate than anticipated and the effect of the merger on the Company’s customer and employee relationships and operating results; changes to U.S. or state tax laws, regulations and government policies concerning the Company’s general business, including changes in interpretation or prioritization and changes in response to prior bank failures and any other risks described in the “Risk Factors” sections of reports filed by the Company with the SEC.

Use of Non-GAAP financial measures In addition to the results presented in accordance with U.S. General Accepted Accounting Principles (“GAAP”), the Company routinely supplements its evaluation with an analysis of certain non-GAAP financial measures. The Company believes these non-GAAP financial measures, in addition to the related GAAP measures, provide meaningful information to investors to help them understand the Company’s operating performance and trends, and to facilitate comparisons with the performance of peers.
