3 FORWARD - LOOKING STATEMENTS This presentation contains forward - looking statements that are based on management’s beliefs, assumptions, current expectations, estimates and projections about the financial services industry, the economy, and ChoiceOne Financial Services, Inc . (ChoiceOne) . Words such as “anticipates,” “believes,” “estimates,” “expects,” “forecasts,” “intends,” “is likely,” “plans,” “predicts,” “projects,” “may,” “could,” “look forward,” “continue”, “future”, and variations of such words and similar expressions are intended to identify such forward - looking statements . All statements with references to future time periods are forward - looking . These 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, implied or forecasted in such forward - looking statements . Furthermore, ChoiceOne undertakes no obligation to update, amend, or clarify forward - looking statements, whether as a result of new information, future events, or otherwise . Additional risk factors include, but are not limited to, the risk factors described in Item 1 A in ChoiceOne’s Annual Report on Form 10 - K for the year ended December 31 , 2023 . NON - GAAP FINANCIAL MEASURES In addition to results presented in accordance with GAAP, this presentation includes certain non - GAAP financial measures . ChoiceOne believes these non - GAAP financial measures provide additional information that is useful to investors in helping to understand underlying financial performance and condition and trends of ChoiceOne . Non - GAAP financial measures have inherent limitations . Readers should be aware of these limitations and should be cautious with respect to the use of such measures . To compensate for these limitations, we use non - GAAP measures as comparative tools, together with GAAP measures, to assist in the evaluation of our operating performance or financial condition . Also, we ensure that these measures are calculated using the appropriate GAAP or regulatory components in their entirety and that they are computed in a manner intended to facilitate consistent period - to - period comparisons . ChoiceOne’s method of calculating these non - GAAP measures may differ from methods used by other companies . These non - GAAP measures should not be considered in isolation or as a substitute for those financial measures prepared in accordance with GAAP or in - effect regulatory requirements . Where non - GAAP financial measures are used, the most directly comparable GAAP or regulatory financial measure, as well as the reconciliation to the most directly comparable GAAP or regulatory financial measure, can be found in this presentation .
