This presentation and the accompanying presentation by management may contain forward-looking statements that are based on management's beliefs, assumptions, current expectations, estimates and projections about the financial services industry, the economy and Chemical Financial Corporation ("Chemical"). Words and phrases such as "anticipates," "believes," "continue," "estimates," "expects," "forecasts," "future," "intends," "is likely," "judgment," "look ahead," "look forward," "on schedule," "on track," "opinion," "opportunity," "plans," "potential," "predicts," "probable," "projects," "should," "strategic," "trend," "will," and variations of such words and phrases or similar expressions are intended to identify such forward-looking statements. These statements include, among others, that Chemical is well-positioned to build market share and enhance revenue growth, plans to invest in commercial lending and banking teams, make key management and operational staff additions and enhance core operating systems, the strength of our loans pipeline, our focus and expectations around building shareholder value, including organic revenue growth, and cost discipline and expanding our market presence and product lines. All statements referencing future time periods are forward-looking. Management's determination of the provision and allowance for loan losses; the carrying value of acquired loans, goodwill and mortgage servicing rights; the fair value of investment securities (including whether any impairment on any investment security is temporary or other-than-temporary and the amount of any impairment); and management's assumptions concerning pension and other postretirement benefit plans involve judgments that are inherently forward-looking. There can be no assurance that future loan losses will be limited to the amounts estimated. All of the information concerning interest rate sensitivity is forward-looking. The future effect of changes in the financial and credit markets and the national and regional economies on the banking industry, generally, and on Chemical, specifically, are also inherently uncertain. Forward-looking are based upon current beliefs and expectations and involve substantial risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such forward-looking statements. Accordingly, such statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions ("risk factors") that are difficult to predict with regard to timing, extent, likelihood and degree of occurrence. Therefore, actual results and outcomes may materially differ from what may be expressed or forecasted in such forward-looking statements. Chemical undertakes no obligation to update, amend or clarify forward-looking statements, whether as a result of new information, future events or otherwise. Forward-Looking Statements & Other Information 2


 
Risk factors include, without limitation: • Chemical's ability to attract and retain new commercial lenders and other bankers as well as key operations staff in light of competition for experienced employees in the banking industry; • Chemical's ability to grow its deposits while reducing the number of physical branches that it operates; • Chemical's ability to control operational expenses; • Negative reactions to the branch closures by Chemical Bank's customers, employees and other counterparties; • Economic conditions (both generally and in our markets) may be less favorable than expected, which could result in, among other things, a deterioration in credit quality, a reduction in demand for credit and a decline in real estate values; • A general decline in the real estate and lending markets, particularly in our market areas, could negatively affect our financial results; • Increased cybersecurity risk, including potential network breaches, business disruptions, or financial losses; • Restrictions or condition imposed by our regulators on our operations may make it more difficult for us to achieve our goals; • Legislative or regulatory changes, including changes in accounting standards and compliance requirements, may adversely affect us; • Changes in the interest rate environment may reduce margins or the volumes or values of the loans we make or have acquired; and • Economic, governmental, or other factors may prevent the projected population, residential, and commercial growth in the markets in which we operate. In addition, risk factors include, but are not limited to, the risk factors described in Item 1A of Chemical’s most recent Annual Report on Form 10-K or disclosed in documents filed or furnished by the Company with or to the SEC after the filing of such Annual Report on Form 10-K. These and other factors are representative of the risk factors that may emerge and could cause a difference between an ultimate actual outcome and a preceding forward-looking statement. Forward-Looking Statements & Other Information (continued) 3


 
Non-GAAP Financial Measures This presentation and the accompanying presentation by management contain certain non-GAAP financial disclosures that are not in accordance with U.S. generally accepted accounting principles ("GAAP"). Such non-GAAP financial measures include Chemical’s tangible shareholders' equity to tangible assets ratio, tangible book value per share, presentation of net interest income and net interest margin on a fully taxable equivalent basis, operating expenses-core (which excludes merger and restructuring expenses and impairment of income tax credits), operating expenses-efficiency ratio (which excludes merger and restructuring expenses, impairment of income tax credits and amortization of intangibles), the adjusted efficiency ratio (which excludes significant items, impairment of income tax credits, loan servicing rights change in fair value gains (losses), amortization of intangibles, net interest income FTE adjustments, (losses) gains from sale of investment securities and closed branch locations) ant other information presented excluding significant items, including net income, diluted earnings per share, return on average assets and return on average shareholders' equity. Chemical uses non-GAAP financial measures to provide meaningful, supplemental information regarding its operational results and to enhance investors’ overall understanding of Chemical’s financial performance. The limitations associated with non-GAAP financial measures include the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might calculate these measures differently. These disclosures should not be considered an alternative to Chemical’s GAAP results. See the Appendix included with this presentation for a reconciliation of the non-GAAP financial measures to the most directly comparable GAAP financial measures.
