MERGER WITH FENTURA FINANCIAL, INC. TRANSACTION OVERVIEW JULY 25, 2024

2 FORWARD-LOOKING STATEMENTS This presentation contains forward-looking statements within the meaning of the federal securities laws relating to the proposed merger with Fentura Financial, Inc. (“Fentura”) by ChoiceOne Financial Services, Inc. (“ChoiceOne” or “COFS”), the integration of Fentura with ChoiceOne, the combination of their businesses and projected or pro forma financial information and metrics. All statements other than statements of historical fact are statements that could be deemed forward-looking statements, including all statements regarding the intent, belief or current expectations of ChoiceOne and Fentura and members of their respective directors and senior management teams. Investors and security holders are cautioned that such statements are predictions, are not guarantees of future performance and actual events or results may differ materially. Completion of the proposed merger, expected financial results or other plans are subject to a number of known and unknown risks, uncertainties and assumptions that are difficult to assess and are subject to change based on factors which are, in many instances, beyond ChoiceOne's control. Additional risks and uncertainties may include, but are not limited to, the risk that expected cost savings, revenue synergies and other financial benefits from the proposed merger may not be realized or take longer than expected to realize, the failure to obtain required regulatory or shareholder approvals, the failure of the closing conditions in the merger agreement to be satisfied or any unexpected delay in closing the transaction. For further information regarding these risks and uncertainties and additional factors that could cause results to differ materially from those contained in the forward-looking statements, see “Risk Factors” and the forward-looking statement disclosure contained in the Annual Report on Form 10-K for the most recently ended fiscal year of ChoiceOne, as well as the proxy statement/prospectus described below, and other documents subsequently filed by ChoiceOne with the Securities and Exchange Commission. Due to these and other possible uncertainties and risks, ChoiceOne can give no assurance that the results contemplated in the forward-looking statements will be realized and readers are cautioned not to place undue reliance on the forward-looking statements contained in this presentation. Forward-looking statements are based on information currently available to ChoiceOne and Fentura, and the parties assume no obligation and disclaim any intent to update any such forward-looking statements. All forward-looking statements, express or implied, included in the presentation are qualified in their entirety by this cautionary statement. 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, non-GAAP measures are used as comparative tools, together with GAAP measures, to assist in the evaluation of operating performance or financial condition. These measures are also calculated using the appropriate GAAP or regulatory components in their entirety and 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 or an alternative for those financial measures prepared in accordance with GAAP or in-effect regulatory requirements. Numbers in this presentation may not sum due to rounding. 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.
