This presentation may contain “forward-looking statements” within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Any statements that are not historical facts, including statements about our expectations, beliefs, plans, strategies, predictions, forecasts, objectives, or assumptions of future events or performance, may be forward-looking. These statements are often, but not always, made through the use of words or phrases such as “anticipates,” “believes,” “expects,” “can,” “could,” “may,” “predicts,” “potential,” “opportunity,” “should,” “will,” “estimate,” “plans,” “projects,” “continuing,” “ongoing,” “expects,” “seeks,” “intends” and similar words or phrases. Accordingly, these statements involve estimates, known and unknown risks, assumptions, and uncertainties that could cause actual strategies, actions, or results to differ materially from those expressed in them, and are not guarantees of timing, future results, events, or performance. Because forward-looking statements are necessarily only estimates of future strategies, actions, or results, based on management’s current expectations, assumptions, and estimates on the date hereof, there can be no assurance that actual strategies, actions or results will not differ materially from expectations. Therefore, readers are cautioned not to place undue reliance on such statements. Factors that could cause or contribute to such differences are changes in general economic, political or industry conditions; changes in monetary and fiscal policies, including the interest rate policies of the Federal Reserve Board; volatility and disruptions in capital and credit markets; the interdependence of financial service companies; changes in regulation or oversight; unfavorable developments concerning credit quality; any future acquisitions or divestitures; the effects of more stringent capital or liquidity requirements; declines or other changes in the businesses or industries of Independent Bank Corporation's customers; the implementation of Independent Bank Corporation's strategies and business models; Independent Bank Corporation's ability to utilize technology to efficiently and effectively develop, market and deliver new products and services; operational difficulties, failure of technology infrastructure or information security incidents; changes in the financial markets, including fluctuations in interest rates and their impact on deposit pricing; competitive product and pricing pressures among financial institutions within Independent Bank Corporation's markets; changes in customer behavior; management's ability to maintain and expand customer relationships; management's ability to retain key officers and employees; the impact of legal and regulatory proceedings or determinations; the effectiveness of methods of reducing risk exposures; the effects of terrorist activities and other hostilities; the effects of catastrophic events; changes in accounting standards and the critical nature of Independent Bank Corporation's accounting policies. Certain risks and important factors that could affect Independent Bank Corporation's future results are identified in its Annual Report on Form 10-K for the year ended December 31, 2019 and other reports filed with the SEC, including among other things under the heading “Risk Factors” in such Annual Report on Form 10-K. Any forward-looking statement speaks only as of the date on which it is made, and Independent Bank Corporation undertakes no obligation to update any forward-looking statement, whether to reflect events or circumstances after the date on which the statement is made, to reflect new information or the occurrence of unanticipated events, or otherwise. 2 Cautionary note regarding forward-looking statements
