FORWARD-LOOKING STATEMENTS
Statements in this report that are not statements of historical fact, including statements that include terms such as ‘‘will,’’ ‘‘may,’’ ‘‘should,’’ ‘‘believe,’’ ‘‘expect,’’ ‘‘forecast,’’ ‘‘anticipate,’’ ‘‘estimate,’’ ‘‘project,’’ ‘‘intend,’’ ‘‘likely,’’ ‘‘optimistic’’ and ‘‘plan’’ and statements about future or projected financial and operating results, plans, projections, objectives, expectations, and intentions, are forward-looking statements. Forward-looking statements include, but are not limited to, descriptions of plans and objectives for future operations, products or services; projections of our future revenue, earnings or other measures of economic performance; forecasts of credit losses and other asset quality trends; statements about our business and growth strategies; and expectations about economic and market conditions and trends. These forward-looking statements express our current expectations, forecasts of future events, or long-term goals. They are based on assumptions, estimates, and forecasts that, although believed to be reasonable, may turn out to be incorrect. Actual results could differ materially from those discussed in the forward-looking statements for a variety of reasons, including:
economic, market, operational, liquidity, credit, and interest rate risks associated with our business including the impact of the ongoing COVID-19 pandemic on each of these items;
economic conditions generally and in the financial services industry, particularly economic conditions within Michigan and the regional and local real estate markets in which our bank operates including the economic impact of the ongoing COVID-19 pandemic in each of these areas;
the failure of assumptions underlying the establishment of, and provisions made to, our allowance for credit losses;
increased competition in the financial services industry, either nationally or regionally;
our ability to achieve loan and deposit growth;
volatility and direction of market interest rates;
the continued services of our management team; and
implementation of new legislation, which may have significant effects on us and the financial services industry.
This list provides examples of factors that could affect the results described by forward-looking statements contained in this report, but the list is not intended to be all-inclusive. The risk factors disclosed in Part I – Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2021, as updated by any new or modified risk factors disclosed in Part II – Item 1A of any subsequently filed Quarterly Report on Form 10-Q, include the known risks our management believes could materially affect the results described by forward-looking statements in this report. However, those risks may not be the only risks we face. Our results of operations, cash flows, financial position, and prospects could also be materially and adversely affected by additional factors that are not presently known to us that we currently consider to be immaterial, or that develop after the date of this report. We cannot assure you that our future results will meet expectations. While we believe the forward-looking statements in this report are reasonable, you should not place undue reliance on any forward-looking statement. In addition, these statements speak only as of the date made. We do not undertake, and expressly disclaim, any obligation to update or alter any statements, whether as a result of new information, future events, or otherwise, except as required by applicable law.
