This document consists of two parts and is part of a registration statement on Form S-3 that ChoiceOne filed with the U.S. Securities and Exchange Commission (“SEC”) utilizing a “shelf registration” process. The first part is this prospectus supplement, which describes the specific terms of this offering and certain other matters and also adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. The second part, the accompanying prospectus, gives more general information about ChoiceOne and the common stock offered by this prospectus supplement and the accompanying prospectus. Some of the information in the accompanying prospectus may not apply to this offering.

This prospectus supplement, the accompanying prospectus and the documents incorporated by reference into this prospectus supplement or the accompanying prospectus may contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, as amended. All statements, other than statements of historical fact, included in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein regarding ChoiceOne’s strategy, future operations, financial position, estimated revenues and income or losses, prospects, plans, and objectives of management are forward-looking statements. When used in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein, the words “anticipate,” “assume,” “believe,” “budget,” “continue,” “could,” “estimate,” “expect,” “future,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “will” and similar terms and phrases are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. Generally, forward-looking statements can be identified by the fact that they are not based on historical facts but instead represent management’s beliefs regarding future events. Such statements are based on management’s current expectations and are subject to risks, uncertainties, and changes in circumstances. Although we believe that these forward-looking statements are based on reasonable assumptions, actual results and outcomes may differ materially from those included in these statements due to a variety of factors. Some of the risks and uncertainties that may cause our actual results, performance or achievements to differ materially from those expressed include, but are not limited to, the following:

The foregoing factors should not be construed as exhaustive and should be read together with the other cautionary statements included or incorporated by reference in this prospectus supplement and accompanying prospectus. You are cautioned not to place undue reliance on forward-looking statements. Forward-looking statements speak only as of the date they were made. Other than as required under United States securities laws, ChoiceOne does not undertake to update, amend, or clarify the forward-looking statements to reflect the impact of circumstances or events that may arise after the date of the forward-looking statements.

We have filed with the SEC a registration statement on Form S-3 under the Securities Act (File No. 333-272337) for the securities being offered by this prospectus supplement.

The SEC allows us to “incorporate by reference” into this prospectus supplement and the accompanying prospectus the information we file with it, which means that we can disclose important information to you by referring you to those documents. The information incorporated by reference is an important part of this prospectus supplement and the accompanying prospectus and information that we subsequently file with the SEC will automatically update and supersede information in this prospectus supplement, the accompanying prospectus, and in our other filings with the SEC.

We incorporate by reference the documents listed below, which we have already filed with the SEC, and any documents we file with the SEC in the future under Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (other than information in such future filings deemed to be furnished and not filed):

You should rely only on the information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. We have not authorized anyone else to provide you with additional or different information. We are only offering these securities in jurisdictions where the offer is permitted.

Investing in our common stock involves risks. You should carefully consider all of the information contained in this prospectus supplement, including the risks and uncertainties described below and under “Cautionary Note Regarding Forward-Looking Statements” in this prospectus supplement, and the other documents incorporated by reference into this prospectus supplement, including the risks and uncertainties described under “Risk Factors” in the accompanying prospectus and our Annual Report on Form 10-K for the year ended December 31, 2023, before making an investment decision. If any of such risks and uncertainties actually occur, our business, financial condition and results of operations could be adversely affected. In that case, the trading price of our common stock could decline, and you may lose all or part of your investment.

We expect the Fentura acquisition to close during the first quarter of 2025, but the acquisition is subject to a number of closing conditions. Satisfaction of many of these conditions is beyond our control. If these conditions are not satisfied or waived, the Fentura acquisition will not be completed. Certain of the conditions that remain to be satisfied include, but are not limited to:

As a result, the Fentura acquisition may not close as scheduled, or at all. In addition, either ChoiceOne or Fentura may terminate the merger agreement under certain circumstances. The closing of this offering is not conditioned on, and is expected to be consummated before, the closing of the Fentura acquisition. Accordingly, if you decide to purchase shares of our common stock in this offering, you should be willing to do so whether or not we complete the Fentura acquisition. If we do not complete the Fentura acquisition, we intend to use the net proceeds from this offering for general corporate purposes, which may include, among other things, investments in or advances to the Bank, working capital, capital expenditures, debt repayment, or the financing of possible acquisitions. There is no assurance that we will be able to profitably deploy the proceeds from this offering if the Fentura acquisition is not consummated. Failure to complete the Fentura acquisition or any delays in completing the Fentura acquisition on the terms and timing we expect could have an adverse impact on our future business, operations and results of operations and could negatively impact the price of our common stock.

Before the Fentura acquisition may be completed, various approvals or waivers must be obtained from bank regulatory authorities, including the Federal Reserve and the Michigan Department of Insurance and Financial Services. These regulators may impose conditions on the completion of, or require changes to the terms of, the Fentura acquisition. Such conditions or changes and the process of obtaining regulatory approvals or waivers could have the effect of delaying completion of the Fentura acquisition or of imposing additional costs or limitations on us

following the completion of the Fentura acquisition. The regulatory approvals or waivers may not be received at all, may not be received in a timely fashion or may contain conditions on the completion of the Fentura acquisition that are burdensome, not anticipated, or cannot be met. If the completion of the Fentura acquisition is delayed, including by a delay in receipt of necessary governmental approvals or waivers, the business, financial condition, and results of operations of ChoiceOne and Fentura may also be materially adversely affected.

From time to time, we evaluate and acquire businesses that we believe complement our existing business. The acquisition component of our growth strategy depends on the successful integration of these acquisitions. We face numerous risks and challenges to the successful integration of acquired businesses, including the following:

If we are unable to successfully integrate the businesses we acquire, our business, financial condition and results of operations may be materially adversely affected.

In response to the announcement of the Fentura acquisition, Fentura’s customers may cease or reduce their business with Fentura, which could negatively affect our combined business operations. Similarly, current or prospective employees of ChoiceOne or of Fentura may experience uncertainty about their future roles with the combined entity. This may adversely affect our ability to attract and retain key management, banking and other personnel. In addition, the diversion of the attention of our respective management teams away from day-to-day operations during the negotiation and pendency of the Fentura acquisition could have an adverse effect on the financial condition and operating results of either us or Fentura.

The pro forma combined consolidated financial information included and incorporated by reference in this prospectus supplement (the “pro forma financial information”) is constructed from our consolidated historical financial statements and the consolidated historical financial statements of Fentura and does not purport to be indicative of the future results of operations of the combined companies. Therefore, this pro forma financial information may not be representative of our results as a combined company. The pro forma financial information is also based in part on certain assumptions regarding the Fentura acquisition and the transactions relating thereto that we believe are reasonable. We cannot assure you, however, that our assumptions will prove to be accurate. Accordingly, the historical and pro forma financial information included and incorporated by reference in this prospectus supplement may not be indicative of what our results of operations and financial condition would have been had we been a consolidated entity during the periods presented, or what our results of operations and financial conditions will be in the future. The challenge of integrating previously independent businesses makes evaluating our business and our future financial prospects difficult. Our potential for future business success and operating profitability must be considered in light of the risks, uncertainties, expenses and difficulties typically encountered by recently combined companies.

Any lawsuits filed in connection with the proposed merger could prevent or delay completion of the merger and result in substantial costs to ChoiceOne and Fentura, including any costs associated with indemnification. The

defense or settlement of any lawsuit or claim that may be filed seeking remedies against ChoiceOne, its board of directors or Fentura or its board of directors in connection with the merger that remains unresolved at the effective time of the merger may adversely affect ChoiceOne’s business, financial condition, results of operations and cash flows.

The success of the Fentura acquisition will depend, in part, on our ability to realize the anticipated benefits and cost savings from combining our business with Fentura’s business. However, to realize these anticipated benefits and cost savings, we must successfully combine both businesses. If we are not able to achieve these objectives, the anticipated benefits and cost savings of the Fentura acquisition may not be realized fully, or at all, or may take longer to realize than we expect.

We expect to incur significant costs associated with completing the Fentura acquisition and integrating Fentura’s operations into our operations and are continuing to assess the impact of these costs. Although we believe that the elimination of duplicate costs, as well as the realization of other efficiencies related to the integration of Fentura’s business with ChoiceOne’s business, will offset incremental transaction and merger-related costs over time, this net benefit may not be achieved in the near term, or at all.

Prior to the completion of the Fentura acquisition, ChoiceOne and Fentura may, by mutual agreement, amend or alter the terms of the merger agreement, including with respect to, among other things, the merger consideration payable by us to Fentura’s shareholders or any covenants or agreements with respect to the parties’ respective operations during the pendency thereof. Any such amendments or alterations may have negative consequences to ChoiceOne.

We believe ChoiceOne’s growth strategy contemplates the future expansion of our business and operations both organically and through acquisitions. Implementing these aspects of our growth strategy depends, in part, on our ability to successfully identify acquisition opportunities and strategic partners that will complement our operating philosophy and to successfully integrate their operations with ours, as well as to generate loans and deposits within acceptable risk and expense tolerances. ChoiceOne may not be able to identify suitable opportunities for further growth and expansion or, if we do, we may not be able to successfully integrate these new operations into our business.

As consolidation of the financial services industry continues, the competition for suitable acquisition candidates may increase. ChoiceOne will compete with other financial services companies for acquisition opportunities, and many of these competitors have greater financial resources than ChoiceOne does and may be able to pay more for an acquisition than we are willing or able to pay.

We can offer no assurance that we will have opportunities to acquire other financial institutions, or that we will complete the Fentura acquisition, or acquire or establish any new branches or mortgage offices, or that we will be able to negotiate, finance and complete any opportunities available to us. Additionally, ChoiceOne may not be able to organically expand into new markets that are profitable for its business. The costs to start up new bank branches and loan production offices in new markets and the additional costs to operate these facilities would increase ChoiceOne’s non-interest expense and may decrease earnings. It may be difficult to adequately and profitably manage growth through the establishment of bank branches and loan production offices in new markets. In addition, we can provide no assurance that our expansion into any such new markets will successfully attract enough new business to offset the expenses of their operation. If we are not able to do so, ChoiceOne’s earnings and stock price may be negatively impacted.

The market price of our common stock could fluctuate significantly due to a number of factors, many of which are beyond our control, including, but not limited to:

In particular, the realization of any of the risks described in this “Risk Factors” section or under the heading “Risk Factors” the accompanying prospectus and in our Annual Report on Form 10-K for the year ended December 31, 2023, which is incorporated herein by reference, could have a material adverse effect on the market price of our common stock and cause the value of our common stock to decline. In addition, the stock market in general, and the market for banks and financial services companies in particular, has experienced price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Securities class action litigation has often been instituted against companies following periods of volatility in the overall market and in the market price of a company’s securities. This litigation, if instituted against ChoiceOne, could result in substantial costs, divert our management’s attention and resources and harm our business, operating results and financial condition.

The trading market for ChoiceOne’s common stock could be influenced by the research and reports that industry or securities analysts may publish about ChoiceOne or its business. If one or more of these analysts cease coverage of ChoiceOne or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. Moreover, if one or more of the analysts who cover ChoiceOne downgrade our common stock or if our operating results do not meet their expectations, either absolutely or relative to our competitors, the price of our common stock could decline.

Future sales or the availability for sale of substantial amounts of our common stock in the public or private markets, or the perception that these sales could occur, could adversely affect the prevailing market price of our common stock and could impair our ability to raise capital through future sales of equity securities.

ChoiceOne’s articles of incorporation currently authorize us to issue up to 15,000,000 shares of common stock and    shares will be outstanding immediately after the completion of this offering (or    shares if the underwriter exercises in full its over-allotment option). In addition, ChoiceOne anticipates that it will issue approximately    shares of common stock in the Fentura acquisition. In connection with the Fentura acquisition, we intend to seek shareholder approval to amend our articles of incorporation to increase the number of authorized shares of ChoiceOne common stock from 15,000,000 shares to 30,000,000 shares.

We may issue shares of our common stock or other securities from time to time as consideration for future acquisitions and investments and pursuant to compensation and incentive plans. If any such acquisition or investment is significant, the number of shares of our common stock, or the number or aggregate principal amount, as the case may be, of other securities that we may issue may in turn be substantial. We may also grant registration rights covering those shares of our common stock or other securities in connection with any such acquisitions and investments.

We cannot predict the size of future issuances of our common stock or the effect, if any, that future issuances and sales of our common stock will have on the market price of our common stock. Sales of substantial amounts of our common stock (including shares of our common stock issued in connection with an acquisition or under a compensation or incentive plan), or the perception that such sales could occur, may adversely affect prevailing market prices for our common stock and could impair our ability to raise capital through future sales of our securities.

ChoiceOne’s primary asset is the Bank. As such, we depend upon the Bank for cash distributions through dividends on the Bank’s stock to pay our operating expenses and satisfy our obligations, including debt obligations. There are numerous laws and banking regulations that limit the Bank’s ability to pay dividends to ChoiceOne. If the Bank is unable to pay dividends to us, we will not be able to satisfy our obligations. Federal and state statutes and regulations restrict the Bank’s ability to make cash distributions to ChoiceOne. These statutes and regulations require, among other things, that the Bank maintain certain levels of capital and retained earnings in order to pay a dividend. Further, federal and state banking authorities have the ability to restrict the Bank’s payment of dividends through supervisory action.

Future dividends, if any, will be declared and paid at the discretion of our board of directors and will depend on a number of factors, including our asset quality, earnings performance, liquidity, capital requirements and other relevant factors. Historically, the principal source of funds used by us to pay cash dividends has been dividends received from the Bank, which are subject to limitations under banking laws and regulations. There can be no assurance of whether or when we may pay dividends in the future.

ChoiceOne’s common stock is not insured by the FDIC or any other government entity. Investment in ChoiceOne’s common stock is subject to risk and potential loss.

For additional risks associated with our common stock, business and industry, see the section entitled “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2023 which is incorporated into this prospectus supplement by reference, as the same may be updated from time to time prior to the completion of this offering by our future filings under the Exchange Act.

We estimate that the net proceeds from this offering will be approximately $  million, or approximately $  million if the underwriter exercises in full its over-allotment option, in each case after deducting the underwriting discount and commissions and our estimated offering expenses.

We intend to use the net proceeds from this offering to support ChoiceOne and Bank regulatory capital ratios in connection with the Fentura acquisition and for other general corporate purposes. This offering is not conditioned on, and is expected to be consummated before, the closing of the Fentura acquisition. If we do not complete the Fentura acquisition, we intend to use the net proceeds from this offering for general corporate purposes, which may include, among other things, investments in or advances to the Bank, working capital, capital expenditures, or debt repayment.

Our management will have broad discretion in the application of the net proceeds from this offering, and investors will be relying on the judgment of our management with regard to the use of these net proceeds.

The following table sets forth ChoiceOne’s capitalization as of June 30, 2024:

This table should be read in conjunction with, and is qualified in its entirety by reference to, the information appearing under the heading “Use of Proceeds” in this prospectus supplement and our historical financial statements and related notes incorporated by reference into this prospectus supplement. This offering is not conditioned on, and is expected to be consummated before, the closing of the Fentura acquisition. There can be no assurance that the Fentura acquisition will be completed. Accordingly, if you decide to purchase shares of common stock in this offering, you should be willing to do so whether or not we complete the Fentura acquisition.

The following discussion is a general summary of the material U.S. federal income tax consequences to “non-U.S. holders” (as defined below) of the acquisition, ownership and disposition of our common stock issued pursuant to this offering, but does not purport to be a complete analysis of all potential tax effects. This discussion is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations promulgated thereunder (“Treasury Regulations”), judicial decisions and published rulings and administrative pronouncements of the Internal Revenue Service (the “IRS”) in effect as of the date hereof and all of which are subject to change or differing interpretation, possibly with retroactive effect, which could affect the U.S. federal income tax consequences described herein. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below, and there can be no assurance that the IRS will not take a different position regarding the tax consequences of a non-U.S. holder’s acquisition, ownership or disposition of our common stock or that any such position would not be sustained by a court.

This discussion is limited to non-U.S. holders who purchase and hold our common stock as a capital asset for U.S. federal income tax purposes (generally property held for investment). This discussion does not address all aspects of U.S. federal income taxation (such as the impact of the unearned income Medicare contribution tax or the alternative minimum tax) that may be applicable to investors in light of their particular circumstances, and does not address any state, local, foreign, or other tax considerations that may be relevant to non-U.S. holders in light of their particular circumstances (such as estate and gift tax laws). In addition, this discussion does not address U.S. federal income tax consequences applicable to a non-U.S. holder who is subject to special treatment under U.S. federal income tax, including, but not limited to:

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our common stock, the U.S. federal income tax treatment of a partner in the partnership generally will depend on the status of the partner, the activities of the partnership, and certain determinations made at the partner level. If you are a partner of a partnership holding our common stock, you should consult your independent tax advisors as to the particular U.S. federal income tax consequences to you of the acquisition, ownership and disposition of our common stock.

THIS DISCUSSION IS FOR GENERAL INFORMATION PURPOSES ONLY AND DOES NOT CONSTITUTE LEGAL ADVICE TO ANY PROSPECTIVE PURCHASER OF OUR COMMON STOCK. IF YOU

ARE CONSIDERING THE PURCHASE OF OUR COMMON STOCK, YOU SHOULD CONSULT YOUR OWN TAX ADVISOR CONCERNING THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE PURCHASING, OWNING, AND DISPOSING OF OUR COMMON STOCK IN LIGHT OF YOUR PARTICULAR CIRCUMSTANCES AND ANY CONSEQUENCES ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR ARISING UNDER THE LAWS OF APPLICABLE STATE, LOCAL, OR FOREIGN TAXING JURISDICTION.

For purposes of this discussion, a “non-U.S. holder” means a beneficial owner of shares of our common stock that is not for U.S. federal income tax purposes:

If distributions are made to non-U.S. holders with respect to our common stock, such distributions will be treated as dividends for U.S. federal income tax purposes to the extent paid of our current earnings and profits or accumulated earnings and profits as determined under the Code, and may be subject to tax as discussed below. Any portion of a distribution that exceeds our current earnings and profits or accumulated earnings and profits will first be applied to reduce the non-U.S. holder’s basis in the common stock and, to the extent such portion exceeds the non-U.S. holder’s basis, the excess will be treated as gain from the disposition of the common stock, the tax treatment of which is discussed below under “—Disposition of Common Stock.” Any distribution described in this paragraph would also be subject to the discussion below under “—Additional Withholding and Reporting Requirements Under FATCA.”

Subject to the discussion below on backup withholding and foreign accounts, any dividends paid to you as a non-U.S. holder of our common stock that are not effectively connected with your trade or business within the United States (as described below) will generally be subject to U.S. federal withholding tax at a rate of 30% on the gross amount of the dividends (or if you are eligible for the benefits of an income tax treaty and certain certification requirements are satisfied, at the lower rate specified by such applicable income tax treaty). A non-U.S. holder who wishes to claim the benefit of an applicable treaty and avoid backup withholding (as discussed below) for dividends will be required to (a) complete IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable successor forms) claiming an exemption from or reduction of the withholding tax under the benefit of an income tax treaty between the United States and the country in which the non-U.S. holder resides or is established and certify under penalty of perjury that such non-U.S. holder is not a United States person as defined under the Code and is eligible for treaty benefits, or (b) if our common stock is held through certain foreign intermediaries, satisfy the relevant certification requirements of applicable Treasury Regulations. A non-U.S. holder for our common stock eligible for a reduced rate of U.S. federal withholding tax under an income tax treaty may obtain a refund of any excess amounts withheld under these rules by timely filing an appropriate claim for refund together with the required information with the IRS.

Subject to the discussion below on backup withholding and foreign accounts, any dividends paid to a non-U.S. holder that are effectively connected with your trade or business within the United States (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a permanent establishment or fixed base in the United States to which such dividends are attributable) will not be subject to U.S. federal withholding tax if the non-U.S. holder provides us or our paying agent with a valid IRS Form W-8ECI (or other applicable successor form) properly certifying such exemption and containing the non-U.S. holder’s taxpayer identification number. Instead, such effectively connected dividends will generally be subject to U.S. federal income tax on a net income basis in

the same manner as if the non-U.S. holder were a United States person under the Code, unless an applicable income tax treaty provides otherwise. In addition, if such non-U.S. holder is treated as a corporation for U.S. federal income tax purposes, such non-U.S. holder may, under certain circumstances, be subject to an additional “branch profits tax” at a rate of 30%, or such lower rate if specified by an applicable income tax treaty, on its effectively connected dividends that such non-U.S. holder receives.

Subject to the discussions below regarding backup withholding and FATCA, a non-U.S. holder generally will not be subject to U.S. federal income or withholding tax on any gain realized upon the disposition of our common stock unless:

A non-U.S. holder described in the first bullet point above will generally be subject to tax on the net gain derived from the disposition under regular graduated U.S. federal income tax rates in the same manner as if the non-U.S. holder was a United States person as defined under the Code. A non-U.S. holder that is a foreign corporation also may, under certain circumstances, be subject to a “branch profits tax” at a rate of 30%, or such lower rate if specified by an applicable income tax treaty, on such effectively connected gains.

An individual non-U.S. holder described in the second bullet point above will generally be subject to a flat 30% tax, or such lower rate if specified by an applicable income tax treaty, on any gain derived from the disposition, which may be offset by certain U.S.-source capital losses of the individual non-U.S. holder (even though the individual is not considered a resident of the United States) provided the individual non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.

A non-U.S. holder described in the third bullet point above, will be subject to the U.S. federal income tax under the regular graduated U.S. federal income tax rates with respect to the gain recognized in the same manner as if the non-U.S. holder were a United States person as defined under the Code, except that the “branch profits tax” will not apply. However, we believe we are not, and we do not anticipate becoming, a USRPHC for U.S. federal income tax purposes.

We generally must report annually to the IRS and to each non-U.S. holder the amount of dividends paid to such non-U.S. holder and the tax withheld with respect to such dividends, regardless of whether withholding was required. Copies of the information returns reporting such dividends and withholding may also be made available under the provisions of an applicable income tax treaty or agreement to the tax authorities in the country in which the non-U.S. holder resides or is established.

A non-U.S. holder will be subject to backup withholding with respect to payments of dividends on our common stock we make to the non-U.S. holder unless non-U.S. holder certifies under penalty of perjury that it is not a United States person as defined under the Code, or otherwise establishes an exemption in the manner described above (the payor or applicable withholding agent does not have actual knowledge or reason to know that such non-U.S. holder is a United States person as defined under the Code, or that the conditions of any other exemption are not, in fact, satisfied).

Depending on the circumstances, information reporting and backup withholding may apply to the proceeds from the disposition of our common stock, unless the non-U.S. holder certifies under penalty of perjury that it is a not a United States person as defined under the Code, or other establishes an exemption in the manner described above (and the payor does not have actual knowledge or reason to know that such non-U.S. holder is a United States person as defined under the Code, or that the conditions of any other exemption are not, in fact, satisfied).

U.S. backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a non-U.S. holder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS. Non-U.S. holders are urged to consult their tax advisors regarding the application of backup withholding in their particular circumstances and the availability of and procedure for obtaining an exemption from backup withholding.

Subject to certain exceptions, the Foreign Account Tax Compliance Act, or “FATCA,” generally imposes a withholding tax of 30% on dividends paid with respect to our common stock to a “foreign financial institution” (as specifically defined under these rules) after December 31, 2018 (regardless of whether the foreign financial institution holds such common stock for its own account or as an intermediary), unless such institution (i) enters into an agreement with the U.S. government and complies with such agreement or (ii) registers with the Internal Revenue Services and complies with an applicable intergovernmental agreement between the United States and a foreign jurisdiction (an “IGA”) or any foreign law implementing an applicable IGA, in either case to, among other things, collect and provide to the United States or other relevant tax authorities certain information regarding U.S. account holders of such institution (which would include certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners). Under certain circumstances, a non-U.S. holder might be eligible for refunds or credits of such withholding taxes.

In addition, subject to certain exceptions, FATCA also generally imposes a withholding tax of 30% on dividends paid with respect to our common stock to a non-financial foreign entity after December 31, 2018, unless such entity provides the withholding agent with a certification that it does not have any substantial U.S. owners or provides information to the withholding agent identifying the substantial U.S. owners of the entity. Under certain circumstances, a non-U.S. holder might be eligible for refunds or credits of such withholding taxes.

Non-U.S. holders are encouraged to consult with their own tax advisors regarding the possible implications of FATCA on their ownership and disposition of our common stock.

We are offering the shares of our common stock described in this prospectus supplement in an underwritten offering in which we, the Bank and D.A. Davidson & Co. (the “underwriter”) are entering into an underwriting agreement with respect to the shares of our common stock being offered hereby. Subject to certain conditions, we will agree to sell, and the underwriter agrees to purchase,    shares of our common stock.

The underwriter is offering the shares of our common stock subject to a number of conditions, including receipt and acceptance of our common stock by the underwriter. The obligations of the underwriter to pay for and accept delivery of the shares offered by this prospectus supplement are subject to these conditions. The underwriting agreement between us and the underwriter provides that if the underwriter defaults, the underwriter may make arrangements, satisfactory to us, for the purchase of common stock by other persons. If such arrangements cannot be made within the timeframe specified in the underwriting agreement and the default exceeds 10% of the total number of shares of common stock that the underwriter is obligated to purchase, this offering will be terminated.

In connection with this offering, the underwriter or securities dealers may distribute offering documents to investors electronically. See the section entitled “—Electronic Distribution.”

Certain of our directors, executive officers and their related persons or entities have indicated an interest in purchasing a portion of the shares of common stock in this offering at a price equal to the public offering price. Because this indication of interest is not a binding agreement or commitment to purchase, these persons could determine to purchase more, less or no shares in this offering or the underwriters could determine to sell more, less or no shares to these persons.

Shares of our common stock sold by the underwriter to the public will be offered at the public offering price set forth on the cover of this prospectus supplement. Any shares of our common stock sold by the underwriter to securities dealers may be sold at a discount of up to $   per share from the public offering price. Any of these securities dealers may resell any shares of our common stock purchased from the underwriter to other brokers or dealers at a discount of up to $   per share from the public offering price. If all of the shares of our common stock are not sold at the public offering price, the underwriter may change the offering price and the other selling terms. Sales of shares of our common stock made outside of the United States may be made by affiliates of the underwriter. The underwriter reserves the right to reject an order for the purchase of shares, in whole or in part.

The underwriting fee is equal to the public offering price per share of common stock less the amount paid by the underwriter to us per share of common stock. The underwriting fee is $   per share. The following table shows the per share and total underwriting discounts to be paid to the underwriter assuming both no exercise and full exercise of the underwriter’s over-allotment option.

We estimate the expenses of this offering, not including the underwriting discount, to be approximately $   million, and such expenses are payable by us. We also have agreed to reimburse the underwriter for its expenses incurred in connection with the offering in an amount up to $150,000.

We have granted the underwriter an option to purchase up to    additional shares of our common stock, at the public offering price set forth on the cover page of this prospectus supplement, less the underwriting discount. The underwriter may exercise this option, in whole or in part, from time to time for a period of 30 days from the date of this prospectus supplement.

We, our executive officers, directors, and certain shareholders are entering into lock-up agreements with the underwriter. Under these agreements, we and each of these persons may not, without the prior written approval of the underwriter and subject to certain exceptions:

These restrictions are subject to customary exceptions and will be in effect for a period of 90 days after the date of this prospectus supplement. At any time and without public notice, the underwriter may, in their sole discretion, waive or release all or some of the securities from these lock-up agreements.

These restrictions also apply to securities convertible into or exchangeable or exercisable for or repayable with our common stock to the same extent as they apply to our common stock. They also apply to common stock owned now or later acquired by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition.

Our common stock is listed on the Nasdaq Capital Market under the symbol “COFS.”

We have agreed to indemnify the underwriter and its affiliates, partners, selling agents, officers and directors and controlling persons against certain liabilities, including under the Securities Act. If we are unable to provide this indemnification, we will contribute to the payments the underwriter and its affiliates, partners, selling agents, officers and directors and controlling persons may be required to make in respect of those liabilities.

To facilitate this offering and in accordance with Regulation M under the Exchange Act, the underwriter may engage in transactions that stabilize, maintain, or otherwise affect the price of our common stock, including:

Stabilizing transactions consist of bids or purchases made for the purpose of preventing or retarding a decline in the market price of our common stock while this offering is in progress. These transactions may also include making short sales of our common stock, which involves the sale by the underwriter of a greater number of shares of common stock than it is required to purchase in this offering. Short sales may be “covered short sales,” which are short positions in an amount not greater than the underwriter’s purchase option referred to above, or may be “naked short sales,” which are short positions in excess of that amount.

The underwriter may close out any covered short position either by exercising its purchase option, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriter will consider, among other things, the price of shares available for purchase in the open market compared to the price at which it may purchase shares

through the purchase option described above. The underwriter must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of our common stock in the open market that could adversely affect investors who purchased in this offering.

As an additional means of facilitating our public offering, the underwriter may bid for, and purchase, shares of our common stock in the open market. The underwriter also may reclaim selling concessions allowed to an underwriter or a dealer for distributing shares of our common stock in this offering, if the underwriter repurchases previously distributed shares of our common stock to cover short positions or to stabilize the price of our common stock.

As a result of these activities, the price of our common stock may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time without notice. The underwriter may carry out these transactions on the Nasdaq Capital Market, in the over-the-counter market or otherwise.

A prospectus supplement in electronic format may be made available by e-mail or on the websites or through online services maintained by the underwriter or its affiliates. In those cases, prospective investors may view offering terms online and may be allowed to place orders online. The underwriters may agree with us to allocate a specific number of shares for sale to online brokerage account holders. Any such allocation for online distributions will be made by the underwriter on the same basis as other allocations. Other than the prospectus supplement in electronic format, the information on the underwriter’s website and any information contained on any other website maintained by the underwriters is not part of this prospectus supplement, has not been approved and/or endorsed by the underwriter or us, and should not be relied upon by investors.

The underwriter and its affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment advisory, investment research, principal investment, hedging, financing, loan referrals, valuation, and brokerage activities. From time to time, the underwriter and/or its affiliates have directly and indirectly engaged, and may in the future engage, in various financial advisory, investment banking loan referrals, and commercial banking services with us and our affiliates, for which they received or paid, or may receive or pay, customary compensation, fees, and expense reimbursement. In the ordinary course of its various business activities, the underwriter and its affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and those investment and securities activities may involve securities and/or instruments of ours. The underwriter and its affiliates may also make investment recommendations and/or publish or express independent research views in respect of those securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in those securities and instruments.

The shares may be sold only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the shares must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement (including any amendment thereto) contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriter is not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

The validity of our common stock offered by this prospectus supplement will be passed upon for us by Warner Norcross + Judd LLP. Certain legal matters in connection with this offering will be passed upon for the underwriter by Hunton Andrews Kurth LLP.

This prospectus provides you with a general description of the securities we may offer.

Certain statements in this prospectus are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, as amended. We use the words “anticipate,” “assume,” “believe,” “budget,” “continue,” “could,” “estimate,” “expect,” “future,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “will” and similar terms and phrases to identify forward-looking statements in this prospectus. In addition, ChoiceOne may make forward-looking statements in our other documents filed with or furnished to the SEC, and our management may make forward-looking statements orally to analysts, investors, representatives of the media, and others.

Generally, forward-looking statements can be identified by the fact that they are not based on historical facts but instead represent management’s beliefs regarding future events. Such statements are based on management’s current expectations and are subject to risks, uncertainties, and changes in circumstances. Actual results and outcomes may differ materially from those included in these statements due to a variety of factors. Some of the risks and uncertainties that may cause our actual results, performance or achievements to differ materially from those expressed include, but are not limited to, the following:

The foregoing factors should not be construed as exhaustive and should be read together with the other cautionary statements included or incorporated by reference in this prospectus.

ChoiceOne is a financial holding company registered under the Bank Holding Company Act of 1956, as amended. The Company was incorporated on February 24, 1986, as a Michigan corporation. The Company was formed to create a bank holding company for the purpose of acquiring all of the capital stock of ChoiceOne Bank, which became a wholly owned subsidiary of the Company on April 6, 1987. ChoiceOne Bank owns all of the outstanding common stock of ChoiceOne Insurance Agencies, Inc., an independent insurance agency headquartered in Sparta, Michigan.

The Company's business is primarily concentrated in a single industry segment, banking. ChoiceOne Bank (referred to as the “Bank”) is a full-service banking institution that offers a variety of deposit, payment, credit and other financial services to all types of customers. These services include time, savings, and demand deposits, safe deposit services, and automated transaction machine services.

The Bank’s consumer loan departments make direct and indirect loans to consumers and purchasers of residential and real property. In addition, the Bank offers trust and wealth management services.

An investment in our securities involves risks. Before making an investment decision, you should carefully consider the risks described under “Risk Factors” in the applicable prospectus supplement and in our most recent Annual Report on Form 10-K, and in our updates to those Risk Factors in our Quarterly Reports on Form 10-Q, and in all other information appearing in this prospectus or incorporated by reference into this prospectus. Material risks and uncertainties that management believes affect ChoiceOne will be described in those documents. In addition to those risk factors, there may be additional risks and uncertainties which we unaware of that could adversely affect our business, financial condition or results of operations. This prospectus is qualified in its entirety by these risk factors.

We intend to use the net proceeds from the sales of the securities offered under this prospectus in the manner and for the purposes set forth in the applicable prospectus supplement. Unless otherwise set forth in an applicable prospectus supplement, we intend to use the net proceeds of any offering of securities sold by us for general corporate purposes.

We may use this prospectus to offer securities in one or more offerings. We will provide a prospectus supplement each time we offer securities which will describe the amounts, prices and detailed terms of the securities. The prospectus supplement will also contain information, where applicable, about material U.S. federal income tax considerations relating to the offered securities, and the securities exchange, if any, on which the offered securities will be listed. To the extent the applicable prospectus supplement is inconsistent with this prospectus, the terms of that prospectus supplement will supersede the information in this prospectus. The terms of the offered securities may differ from the terms summarized below. Additionally, the descriptions in this prospectus and the applicable prospectus supplement do not contain all of the information that you may find useful or that may be important to you. You should refer to the provisions in the applicable prospectus supplement which define your rights as holders of the relevant securities.

The following is a summary of the material terms, limitations, voting powers and relative rights of our capital stock as contained in our Restated Articles of Incorporation (“Articles”), which are incorporated by reference herein. This summary does not purport to be a complete description of the terms and conditions of our capital stock in all respects and is subject to and qualified in its entirety by reference to our Articles, our Bylaws, the Michigan Business Corporation Act (“MBCA”) and any other document referenced in the summary descriptions and from which the summary descriptions are derived. Although we believe this summary covers the material terms and provisions of our capital stock set forth in our Articles, it may not contain all of the information that is important to you.

Our authorized capital stock consists of 15,000,000 shares of common stock, no par value, and 100,000 shares of preferred stock, no par value. As of April 30, 2023, there were 7,521,749 shares of ChoiceOne common stock issued and outstanding, and no shares of ChoiceOne preferred stock were outstanding. ChoiceOne's common stock trades on the NASDAQ Capital Market under the trading symbol “COFS.” ChoiceOne's transfer agent is Continental Stock Transfer & Trust Company.

We may issue shares of our no par value common stock, separately or together with, or upon conversion, exercise or exchange of other securities, as set forth in the applicable prospectus supplement.

Each share of common stock has the same relative powers, preferences and rights as, and is identical in all respects with, all the other shares of common stock. Holders of ChoiceOne common stock have no conversion rights and are not entitled to any preemptive or subscription rights. ChoiceOne common stock is not subject to redemption or any further calls or assessments. ChoiceOne common stock does not have cumulative voting rights in the election of directors.

Each holder of common stock is entitled to one vote for each share held by such shareholder. The ChoiceOne Bylaws provide that any action required or permitted to be taken at a meeting of the ChoiceOne shareholders may be taken without a meeting, without prior notice, and without a vote, if all the shareholders entitled to vote at the meeting consent in writing. Except as otherwise provided in ChoiceOne's Articles, Bylaws, or applicable law, a majority of the votes cast at a meeting is required to take any action. Directors are elected by a vote of the plurality of the votes cast with respect to the director at any meeting for the election of directors.

In the event ChoiceOne liquidates, dissolves or winds up, each holder of ChoiceOne common stock will be entitled to receive a pro rata portion of all assets available for distribution, after ChoiceOne pays or provides for payment of all of ChoiceOne's debts and liabilities and of any amounts owing to holders of any outstanding shares of any class having preference over ChoiceOne common stock in such event.

Holders of ChoiceOne common stock are entitled to receive dividends, if any, as may be declared by ChocieOne's board of directors out of assets legally available therefor after payment to holders of any outstanding

shares of any class having preference over ChoiceOne common stock as to the payment of dividends. The amount of and nature of any dividends declared on ChoiceOne common stock will be determined by ChoiceOne's board of directors in their sole discretion.

We may issue shares of our no par value preferred stock in one or more series, as set forth in the applicable prospectus supplement.

Our Articles authorize the issuance of up to 100,000 shares of preferred stock, no par value. We will describe the particular terms of any series of preferred stock being offered in the applicable prospectus supplement relating to that series of preferred stock. Those terms may include:

The voting rights of preferred stock of any series being offered will be described in the applicable prospectus supplement.

In the event ChoiceOne liquidates, dissolves or winds up, holders of our preferred stock will be entitled to receive liquidating distributions in the amount set forth in the applicable prospectus supplement before we make any distribution of assets to holders of our common stock or any junior series of preferred stock.

If you purchase preferred stock being offered by use of this prospectus or an applicable prospectus supplement, you will be entitled to receive, when, as and if declared by our board of directors, dividends at the rates and on the dates set forth in the prospectus supplement.

The applicable prospectus supplement will state the terms, if any, on which shares of a series of preferred stock being offered are convertible into shares of our common stock or another series of our preferred stock.

The applicable prospectus supplement will state the terms, if any, on which shares of a series of preferred stock being offered may be redeemed.

The ChoiceOne Articles provide that the board of directors is divided into three classes. Each class of directors is as equal as possible in number and serves for a three-year term of office, except that directors may be elected for shorter terms so that approximately one-third of the directors are elected each year. One class of ChoiceOne’s directors is elected each year, to hold office for a three-year term (or until their respective successors are elected and qualified, or until their respective resignation or removal). ChoiceOne’s board currently consists of 15 directors.

In the future, ChoiceOne's board of directors may authorize the issuance of additional shares of common stock or preferred stock, up to the amounts authorized in the ChoiceOne Articles. Generally, no shareholder approval would be required for the issuance of these additional shares, subject only to the restrictions of the Michigan Business Corporation Act and the ChoiceOne Articles.

The ChoiceOne Articles may be amended by the affirmative vote of the holders of a majority of the outstanding ChoiceOne shares entitled to vote, except that certain provisions of the ChoiceOne Articles related to directors, interested party transactions, business combinations and tender or exchange offers, and amendment of the ChoiceOne Articles may be amended only by the affirmative vote of at least 66 2/3% of the outstanding ChoiceOne shares entitled to vote. ChoiceOne's Bylaws may be amended by the affirmative vote of a majority of the board of directors or by the affirmative vote of the holders of a majority of the outstanding ChoiceOne shares entitled to vote.

Certain provisions of our Articles and Bylaws may have the effect of impeding the acquisition of control of the Company by means of a tender offer, proxy fight, open-market purchases or otherwise in a transaction not approved by our board of directors. The ChoiceOne Articles include certain provisions related to business combinations with a person who owns 10% or more of the outstanding ChoiceOne stock or who is an affiliate who in the past two years owned 10% or more of the outstanding ChoiceOne stock. Such business combinations require approval by the affirmative vote of the holders of at least 66 2/3% of outstanding ChoiceOne stock (other than stock held by certain related persons involved in such business combination). However, approval by the affirmative vote of the holders of only a majority of outstanding ChoiceOne stock is required if the business combination has been approved by a vote of a majority of disinterested directors or if payment to shareholders in connection with the business combination is solely in cash and certain additional conditions are met.

The following is a summary of the general terms of the deposit agreement to govern any depositary shares we may offer representing fractional interests in shares of our preferred stock, the depositary shares themselves and the related depositary receipts. This summary does not purport to be complete in all respects and is subject to and qualified entirely by reference to the relevant deposit agreement and depositary receipt with respect to the depositary shares relating to any particular series of preferred stock. The specific terms of any depositary shares we may offer will be described in the applicable prospectus supplement. If so described in the applicable prospectus supplement, the terms of that series of depositary shares may differ from the general description of terms presented below.

We may offer fractional interests in our shares of our preferred stock, rather than full shares of preferred stock. If we do, we will provide for issuance by a depositary to the public of receipts for depositary shares, each of which will represent a fractional interest in a share of a particular series of preferred stock.

The shares of any series of preferred stock underlying the depositary shares will be deposited under a separate deposit agreement between us and a bank or trust company having its principal office in the United States and having a combined capital and surplus of such amount as may be set forth in the applicable prospectus supplement, which

we refer to in this section as the depositary. We will name the depositary in the applicable prospectus supplement. Subject to the terms of the deposit agreement, each owner of a depositary share will have a fractional interest in all the rights and preferences of the preferred stock underlying the depositary share.

The depositary shares will be evidenced by depositary receipts issued under the deposit agreement. Purchasers of fractional interests in shares of the related series of preferred stock will receive depositary receipts as described in the applicable prospectus supplement.

Unless we specify otherwise in the applicable prospectus supplement, purchasers will not be entitled to receive the whole shares of preferred stock underlying the depositary shares.

Upon receipt of notice of any meeting at which the holders of our preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary shares underlying our preferred stock. Each record holder of such depositary shares on the record date, which will be the same date as the record date for the preferred stock, will be entitled to instruct the depositary as to how the preferred stock underlying the holder’s depositary shares should be voted.

If a series of our preferred stock underlying the depositary shares has a liquidation preference, in the event of liquidation, dissolution, or winding up, holders of depositary shares will be entitled to receive the fraction of the liquidating distributions accorded each share of the applicable series of our preferred stock, as set forth in the applicable prospectus supplement.

The depositary will distribute cash dividends or other cash distributions, if any, received in respect of the preferred stock underlying the depositary shares to the record holders of depositary shares based on the number of depositary shares owned by that holder on the relevant record date. The relevant record date for depositary shares will be the same date as the record date for our preferred stock.

If there is a distribution other than in cash, the depositary will distribute the property to the entitled record holders of depositary shares, unless the depositary determines that it is not feasible to make that distribution. In that case, the depositary may, with our approval, adopt the method it deems equitable and practicable for making that distribution, including any sale of property and distribution of the net proceeds from this sale to the applicable holders.

If a series of our preferred stock underlying the depositary shares is subject to conversion or exchange, the applicable prospectus supplement will describe the rights or obligations of each record holder of depositary receipts to convert or exchange the depositary shares.

If a series of our preferred stock underlying the depositary shares is subject to redemption, the depositary shares will be redeemed from the proceeds received by the depositary resulting from the redemption, in whole or in part, of our preferred stock held by the depositary. Whenever we redeem any of our preferred stock held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing our preferred stock so redeemed. The depositary will mail the notice of redemption to the record holders of the depositary receipts promptly upon receiving the notice from us, unless otherwise provided in the applicable prospectus supplement, prior to the date fixed for redemption of our preferred stock.

The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may be amended by agreement between us and the depositary at any time. However, certain amendments as specified in the applicable prospectus supplement will not be effective unless approved by the record holders of at least a majority

of the depositary shares then outstanding. A deposit agreement may be terminated by the depositary or us only if: (1) all outstanding depositary shares have been redeemed; or (2) there has been a final distribution of our preferred stock in connection with our dissolution and the distribution has been made to all holders of depositary shares.

We will pay all United States transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangement. We will also pay charges of the depositary for the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary shares will pay transfer and other taxes and governmental charges and any other charges that are stated to be their responsibility in the deposit agreement.

The depositary may resign at any time by delivering notice to us. We may also remove the depositary at any time. Resignations or removals will take effect when a successor depositary is appointed and it accepts the appointment.

The debt securities that we may offer using this prospectus consist of notes, debentures or other evidences of indebtedness. Any debt securities that we offer and sell will be our direct obligations. Debt securities may be issued in one or more series. All debt securities of any one series need not be issued at the same time, and unless otherwise provided, a series of debt securities may be reopened, without the consent of the holders of outstanding debt securities, for issuance of additional debt securities of that series or to establish additional terms of that series of debt securities (with such additional terms applicable only to unissued or additional debt securities of that series). As required by the Trust Indenture Act of 1939, as amended, for all debt securities that are publicly offered, such debt securities will be governed by a document called an indenture. The form of indenture is subject to any amendments or supplements that we may enter into with the trustee(s) setting forth the specific terms and conditions of the debt securities being issued. The indenture is filed as an exhibit to the registration statement of which this prospectus forms a part. The material terms of the indenture are summarized below and we refer you to the indenture for a detailed description of these material terms. Additional or different provisions that are applicable to a particular series of debt securities will, if material, be described in a prospectus supplement relating to the offering of debt securities of that series. These provisions may include, among other things and to the extent applicable, the following:
