INFORMATION ABOUT VOTING

Who May Vote at the Meeting

You are entitled to vote your shares of Rhinebeck Bancorp common stock if you owned your shares as of the close of business on March 28, 2024. As of the close of business on that date, 11,072,607 shares of common stock were outstanding, of which 6,345,975 shares were owned by Rhinebeck Bancorp, MHC and the remaining 4,726,632 shares were owned by public stockholders. Each share of common stock has one vote.

Our Articles of Incorporation provide that record holders of our common stock who beneficially own, either directly or indirectly, more than 10% of our outstanding shares (other than Rhinebeck Bancorp, MHC) are not entitled to any vote with respect to the shares held in excess of the 10% limit.

Ownership of Shares

You may own your shares of common stock of Rhinebeck Bancorp in one or more of the following ways:

● Directly in your name as the stockholder of record;

● Indirectly through a broker, bank or other holder of record in “street name”; or

● Indirectly through the Rhinebeck Bank Employee Stock Ownership Plan (the “ESOP”) or the Rhinebeck Bank 401(k) Plan (the “401(k) Plan”).

If your shares are registered directly in your name, you are the holder of record of those shares and we are sending these proxy materials directly to you. As the holder of record, you have the right to give your proxy directly to us to vote at the annual meeting or you may vote online at the annual meeting.

If you hold your shares in “street name,” you are considered the beneficial owner of your shares and your broker, bank or other holder of record is sending these proxy materials to you. As the beneficial owner, you have the right to direct your broker, bank or other holder of record how to vote by completing a voting instruction form provided by your broker, bank or other holder of record that accompanies your proxy materials. Your broker, bank or other holder of record may allow you to provide voting instructions by telephone or via the Internet. Refer to the voting instruction form that accompanies your proxy materials. If you want to vote your shares of common stock held in street name online at the annual meeting, you must obtain a written proxy in your name from the broker, bank or other holder who is the record holder of your shares.

1

If you are a participant in the ESOP or own shares of common stock indirectly through the 401(k) Plan, see “Participants in the ESOP and the 401(k) Plan” below.

Attending the Meeting

The annual meeting will be a virtual meeting of stockholders, which will be conducted exclusively by webcast. No physical meeting will be held. You are entitled to participate in the annual meeting only if you were a stockholder of Rhinebeck Bancorp as of the close of business on March 28, 2024, or if you hold a valid proxy for the annual meeting.

You will be able to attend the annual meeting online and submit your questions and vote your shares during the meeting by visiting www.cstproxy.com/rhinebeckbancorp/2024. The online meeting will begin promptly at 11:00 a.m., Eastern time. We encourage you to access the meeting before the start time leaving ample time to check in. To participate in the annual meeting, you will need the 12-digit control number included on your proxy card.

If you hold your shares through an intermediary, such as a bank or broker, you must register in advance using the instructions below. To register to attend the annual meeting online, you must submit proof of your proxy power (legal proxy) reflecting your Rhinebeck Bancorp stock holdings along with your name and e-mail address to our transfer agent, Continental Stock Transfer.

Quorum and Vote Required

Quorum. We will have a quorum and be able to conduct the business of the annual meeting if a majority of the outstanding shares of Rhinebeck Bancorp common stock entitled to vote, represented online or by proxy, is present at the meeting.

Votes Required for Proposals. At this year’s annual meeting, stockholders will elect three directors to serve for a term of three years. In voting on the election of directors (Item 1), you may vote in favor of the nominees or withhold your vote as to any or all of the nominees. There is no cumulative voting for the election of directors. Directors must be elected by a plurality of the votes cast at the annual meeting. This means that the nominees receiving the largest number of votes cast will be elected up to the maximum number of directors to be elected at the annual meeting. The maximum number of directors to be elected at the annual meeting is three.

In voting on the ratification of the appointment of the independent registered public accounting firm (Item 2), you may vote in favor of the proposal, vote against the proposal or abstain from voting. The affirmative vote of a majority of the votes cast at the annual meeting is required to approve this proposal.

Because Rhinebeck Bancorp, MHC owns more than 50% of the outstanding shares of Rhinebeck Bancorp common stock, the votes cast by Rhinebeck Bancorp, MHC will ensure the presence of a quorum and will decide the outcome of the vote on the election of directors (Item 1) and the ratification of the appointment of the independent registered public accounting firm (Item 2).

Effect of Not Casting Your Vote

If you hold your shares in street name, it is critical that you cast your vote if you want it to count in the election of directors (Proposal 1). Current regulations restrict the ability of your bank, broker or other holder of record to vote your shares on the election of directors and certain other matters on a discretionary basis. Therefore, if you hold your shares in street name and you do not instruct your bank, broker or other holder of record on how to vote on the election of directors, no votes will be cast on your behalf. These are referred to as “broker non-votes.” Your bank, broker or other holder of record, however, does have discretion to vote any shares for which you do not provide instructions on how to vote on the ratification of the appointment of the independent registered public

2

accounting firm (Item 2). If you are a stockholder of record and you do not cast your vote, no votes will be cast on your behalf on any of the items of business at the annual meeting.

How We Count the Votes

If you return valid proxy instructions or attend the meeting and vote online at the meeting, we will count your shares to determine whether there is a quorum, even if you abstain from voting. Broker non-votes also will be counted to determine the existence of a quorum.

In counting votes on the election of directors or the proposal to ratify the appointment of the independent registered public accounting firm, broker non-votes and abstentions will have no effect.

Voting by Proxy Card

The Board of Directors of Rhinebeck Bancorp is sending you this proxy statement to request that you allow your shares of Rhinebeck Bancorp common stock to be represented at the annual meeting by the persons named on the proxy card. If you are a registered stockholder, you may vote by completing and mailing the enclosed proxy card. All shares of Rhinebeck Bancorp common stock represented at the annual meeting by properly executed and dated proxies will be voted according to the instructions indicated on the proxy card. If you sign, date and return a proxy card without giving voting instructions, your shares will be voted as recommended by our Board of Directors.

The Board of Directors unanimously recommends a vote:

● “FOR” each nominee for director; and

● “FOR” the ratification of the appointment of Wolf & Company, P.C. to serve as the independent registered public accounting firm for the year ending December 31, 2024.

If any matters not described in this proxy statement are properly presented at the annual meeting, the persons named in the proxy card will use their judgment as to how to vote your shares. This includes a motion to adjourn or postpone the annual meeting to solicit additional proxies. If the annual meeting is postponed or adjourned, your common stock may be voted by the persons named in the proxy card on the new meeting date as well, unless you have revoked your proxy. We do not know of any other matters to be presented at the annual meeting.

Voting via the Internet

Instead of voting by mailing a proxy card, registered stockholders can vote their shares of Rhinebeck Bancorp common stock via the Internet. The Internet voting procedures are designed to authenticate stockholders’ identities, allow stockholders to provide their voting instructions and confirm that their instructions have been recorded properly. Specific instructions for Internet voting are set forth on the proxy card. The deadline for voting via the Internet in advance of the meeting is 11:59 p.m., Eastern time, on May 20, 2024.

You can also attend the virtual annual meeting and vote online during the meeting by following the instructions above under “—Attending the Meeting.”

Revoking Your Proxy

Whether you vote by mail or via the Internet, if you are a registered stockholder, you may revoke your proxy by:

● sending a written statement to that effect to our Corporate Secretary;

● submitting a properly signed proxy card with a later date;

● voting via the Internet at a later time so long as such vote is received by the applicable time and date set forth above for registered stockholders; or

● voting online at the annual meeting (Note: Attendance online at the annual meeting will not in itself constitute revocation of your proxy).

3

If you hold your shares through a bank, broker, trustee or nominee and you have instructed the bank, broker, trustee or nominee to vote your shares, you must follow the directions received from your bank, broker, trustee or nominee to change those instructions.

Participants in the ESOP and the 401(k) Plan

If you are a participant in the ESOP, you will receive a voting instruction card that reflects all the shares that you may direct the ESOP trustee to vote on your behalf under the ESOP. Under the terms of the ESOP, the ESOP trustee votes all shares held by the ESOP, but you may direct the trustee how to vote the shares of Rhinebeck Bancorp common stock allocated to your ESOP account. The ESOP trustee will vote all unallocated shares of Rhinebeck Bancorp common stock held by the ESOP and allocated shares for which no voting instructions are received in the same proportion as shares for which it has received timely voting instructions.

If you hold Rhinebeck Bancorp common stock in the 401(k) Plan, you will receive a voting instruction card that reflects all shares that you may direct the 401(k) Plan trustee to vote on your behalf under the 401(k) Plan. Under the terms of the 401(k) Plan, you may direct the 401(k) Plan trustee how to vote the shares allocated to your account. If the 401(k) Plan trustee does not receive your voting instructions, the 401(k) Plan trustee will be instructed to vote your shares in the same proportion as the voting instructions received from other 401(k) Plan participants.

The deadline for returning your voting instruction cards to the ESOP trustee and/or the 401(k) Plan trustee is May 14, 2024.

CORPORATE GOVERNANCE

General

We periodically review our corporate governance policies and procedures to ensure that they meet the highest standards of ethical conduct, report results with accuracy and transparency and fully comply with the laws, rules and regulations that govern our operations.

Director Independence

The Board of Directors currently consists of nine members, all of whom are considered independent under the listing standards of the Nasdaq Stock Market, except for Michael J. Quinn who serves as the President and Chief Executive Officer of Rhinebeck Bancorp and Rhinebeck Bank. In determining the independence of directors, the Board of Directors has considered transactions, relationships and other arrangements between Rhinebeck Bancorp and its directors that are not required to be disclosed in this proxy statement under the heading “Other Information Relating to Directors and Executive Officers—Transactions With Related Persons,” including legal services performed by Suzanne Rhulen Loughlin’s husband and business services performed by Christopher Chestney’s brother-in-law.

Board Leadership Structure and Board’s Role in Risk Oversight

The Board of Directors has determined that the separation of the offices of Chairman of the Board and President and Chief Executive Officer enhances Board independence and oversight. Moreover, the separation of these offices allows the President and Chief Executive Officer to better focus on his growing responsibilities of managing the daily operations of Rhinebeck Bancorp and Rhinebeck Bank, while allowing the Chairman of the Board to lead the Board of Directors in its fundamental role of providing advice to and independent oversight of management. William C. Irwin currently serves as the Chairman of the Board and is independent under the listing standards of the Nasdaq Stock Market.

Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including credit risk, interest rate risk, liquidity risk, operational risk, strategic risk and reputation risk. Management is responsible for the day-to-day management of the risks that Rhinebeck Bancorp faces, while the Board of Directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, the Board of Directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed. Senior management also attend Board meetings and are available to address any questions or concerns raised by the Board of Directors on risk management and any other matters.

4

Committees of the Board of Directors

The following table identifies Rhinebeck Bancorp’s standing committees and their members as of March 31, 2024. All members of each committee are independent in accordance with the listing requirements of the Nasdaq Stock Market. Each committee operates under a written charter that is approved by the Board of Directors that governs its composition, responsibilities and operation. Each committee reviews and reassesses the adequacy of its charter at least annually. The charters of all three committees are available in the Corporate Governance portion of the Investor Relations section of Rhinebeck Bank’s website (www.rhinebeckbank.com).

Audit Committee. The Audit Committee meets periodically with the independent registered public accounting firm and management to review accounting, auditing, internal control structure and financial reporting matters. The committee also receives and reviews the reports and findings and other information presented to them by Rhinebeck Bancorp’s officers regarding financial reporting policies and practices. The Audit Committee also reviews the performance of Rhinebeck Bancorp’s independent registered public accounting firm, the internal audit function and oversees policies associated with financial risk assessment and risk management. The Audit Committee selects the independent registered public accounting firm and meets with them to discuss the results of the annual audit and any related matters. The Board has determined that Steven E. Howell qualifies as an “audit committee financial expert” as defined under applicable Securities and Exchange Commission rules.

Compensation Committee. The Compensation Committee approves the compensation objectives for Rhinebeck Bancorp and Rhinebeck Bank, establishes the compensation for the President and Chief Executive Officer and other executives and reviews personnel policies. The Compensation Committee reviews components of compensation including base salary, bonus, benefits and other perquisites. The President and Chief Executive Officer makes recommendations to the Compensation Committee from time to time regarding the appropriate mix and level of compensation for other officers. Decisions by the Compensation Committee with respect to the compensation of executive officers are approved by the full Board of Directors. The Compensation Committee also assists the Board of Directors in evaluating potential candidates for executive positions. The Compensation Committee is also responsible for administering the Rhinebeck Bancorp, Inc. 2020 Equity Incentive Plan and approving grants under the plan. The Committee may form and delegate authority to subcommittees when appropriate.

The Compensation Committee, in conjunction with the Governance and Nominating Committee, also considers the appropriate levels and form of director compensation and makes recommendations to the Board of Directors regarding director compensation.

Governance and Nominating Committee. The Governance and Nominating Committee takes a leadership role in shaping governance policies and practices, including recommending to the Board of Directors the corporate governance policies and guidelines applicable to Rhinebeck Bancorp and monitoring compliance with these policies and guidelines. In addition, the Governance and Nominating Committee is responsible for identifying individuals qualified to become Board members and recommending to the Board the director nominees for election at the next annual meeting of stockholders. The committee also recommends director candidates for each committee for appointment by the Board.

Considerations Respecting Director Nominees and Candidates

Minimum Qualifications for Director Nominees. The Board of Directors has adopted criteria that it considers when it selects individuals to be nominated for election to the Board of Directors. A candidate must meet the eligibility requirements set forth in our Bylaws, which include an age limitation provision and a requirement that the candidate must not have been subject to certain criminal

5

or regulatory actions. A candidate also must meet any qualification requirements set forth in any Board of Directors or committee governing documents.

If a candidate is deemed eligible for election to the Board of Directors, the Board of Directors will then evaluate the following criteria in selecting nominees:

● contributions to the range of talent, skill and expertise of the Board of Directors;

● financial, regulatory and business experience, knowledge of the banking and financial service industries, familiarity with the operations of public companies and ability to read and understand financial statements;

● familiarity with our market area and participation in and ties to local businesses and local civic, charitable and religious organizations;

● personal and professional integrity, honesty and reputation;

● the ability to represent the best interests of our stockholders and Rhinebeck Bancorp;

● the need for gender and ethnic diversity on the Board;

● current equity holdings in Rhinebeck Bancorp;

● the ability to devote sufficient time and energy to the performance of his or her duties; and

● independence, as that term is defined under applicable Securities and Exchange Commission and stock exchange listing criteria.

The Board of Directors will also consider any other factors it deems relevant, including the size of the Board of Directors and pertinent regulatory disclosure obligations.

When nominating an existing director for re-election to the Board of Directors, the Board of Directors will consider and review an existing director’s attendance and performance at Board and committee meetings; length of Board service; the experience, skills and contributions that the existing director brings to the Board; and independence.

Director Nomination Process. The Board of Directors follows the following process to identify and evaluate individuals to be nominated for election to the Board of Directors:

For purposes of identifying nominees for the Board of Directors, the Board of Directors relies on personal contacts of the committee members and other members of the Board of Directors, as well as their knowledge of members of the communities that Rhinebeck Bank serves. The Board of Directors will also consider director candidates recommended by stockholders according to the policy and procedures set forth below. The Board of Directors has not previously used an independent search firm to identify nominees.

In evaluating potential nominees, the Board of Directors determines whether the candidate is eligible and qualified for service on the Board of Directors by evaluating the candidate under the criteria set forth above. If such individual fulfills these criteria, the Board of Directors will conduct a check of the individual’s background and interview the candidate to further assess the qualities of the prospective nominee and the contributions he or she would make to the Board.

Consideration of Director Candidates Recommended by Stockholders. The policy of the Board of Directors is to consider director candidates recommended by stockholders who appear to be qualified to serve on our Board of Directors. The Board of Directors may choose not to consider an unsolicited recommendation if no vacancy exists on the Board of Directors and the Board of Directors does not perceive a need to increase the size of the Board of Directors. The Board of Directors will consider only those director candidates recommended by stockholders in accordance with the procedures set forth below.

Procedures to be Followed by Stockholders. To submit a recommendation of a director candidate to the Board of Directors, a stockholder should submit the following information in writing, addressed to the Chairman of the Board of Directors, care of the Corporate Secretary, at our main office:

● A statement that the writer is a stockholder and is proposing a candidate for consideration by the Board of Directors;

6

● The name and address of the stockholder as they appear on our books, and of the beneficial owner, if any, on whose behalf the nomination is made;

● The class or series and number of shares of our capital stock that are owned beneficially or of record by such stockholder and such beneficial owner;

● A description of all arrangements or understandings between such stockholder and each proposed nominee and any other person or persons (including their names) pursuant to which the nomination(s) are to be made by such stockholder;

● A representation that such stockholder intends to appear in person or by proxy at the meeting to nominate the nominee named in the stockholder’s notice;

● The name, age, personal and business address of the candidate and the principal occupation or employment of the candidate;

● The candidate’s written consent to be nominated and, if elected, to serve as a director;

● A statement of the candidate’s business and educational experience and all other information relating to such person that would indicate such person’s qualification to serve on the Board of Directors;

● An affidavit that the candidate would not be disqualified under any of the required Director Qualifications set forth in Article II, Section 12 of Rhinebeck Bancorp’s Bylaws; and

● Such other information regarding the candidate or the stockholder as would be required to be included in our proxy statement pursuant to Schedule 14A of the Securities and Exchange Commission.

For a director candidate to be considered for nomination at an annual meeting of stockholders, the Board of Directors must receive the recommendation by not less than 90 but not more than 120 calendar days before the date our proxy statement was released to stockholders in connection with the previous year’s annual meeting, advanced by one year. See “Submission of Stockholder Business Proposals and Nominations” for more information.

Board and Committee Meetings

The business of Rhinebeck Bancorp and Rhinebeck Bank is conducted through meetings and activities of their respective Board of Directors and committees. During the year ended December 31, 2023, the Board of Directors of Rhinebeck Bancorp held 12 meetings and the Board of Directors of Rhinebeck Bank held 15 meetings. No director attended fewer than 75% of the total meetings of the Board of Directors and of the committees on which that director served.

Director Attendance at Annual Meeting

While Rhinebeck Bancorp has no formal policy on director attendance at annual meetings of stockholders, directors are encouraged to attend. All directors, except for three, attended the 2023 annual meeting of stockholders.

Code of Ethics for Senior Officers

We maintain a Code of Ethics for Senior Officers, which includes our principal executive officer and principal financial officer, that addresses conflicts of interest, the treatment of confidential information, and compliance with applicable laws, rules and regulations. In addition, it is designed to deter wrongdoing and promote honest and ethical conduct, the avoidance of conflicts of interest, full and accurate disclosure and compliance with all applicable laws, rules and regulations. The Code of Ethics for Senior Officers is available in the Corporate Governance portion of the Investor Relations section of Rhinebeck Bank’s website (www.rhinebeckbank.com).

Hedging Policy

Rhinebeck Bancorp’s Insider Trading Policy includes a prohibition on hedging by its directors and executive officers. Hedging transactions are designed to hedge or offset the economic risk of owning shares of Company common stock. Accordingly, any hedging, derivative or other equivalent transaction that is specifically designed to reduce or limit the extent to which declines in the trading price of Company common stock would affect the value of the shares of Company common stock owned by an executive officer or director is prohibited.

REPORT OF THE AUDIT COMMITTEE

Rhinebeck Bancorp’s management is responsible for Rhinebeck Bancorp’s internal controls and financial reporting process. Our independent registered public accounting firm is responsible for performing an independent audit of our financial statements and issuing an opinion on the conformity of those financial statements with generally accepted accounting principles in the United States of America (“GAAP”). The Audit Committee oversees Rhinebeck Bancorp’s internal controls and financial reporting process on behalf of the Board of Directors.

In this context, the Audit Committee has met and held discussions with management and the independent registered public accounting firm. Management represented to the Audit Committee that Rhinebeck Bancorp’s financial statements were prepared in accordance with GAAP and the Audit Committee has reviewed and discussed the financial statements with management and the independent registered public accounting firm. The Audit Committee discussed with the independent registered public accounting firm the matters required to be discussed by the Public Company Accounting Oversight Board (the “PCAOB”), which include matters related to the audit of the financial statements.

In addition, the Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm the firm’s independence from Rhinebeck Bancorp and its management. In concluding that the registered public accounting firm is independent, the Audit Committee considered, among other factors, whether any non-audit services provided by the firm were compatible with its independence.

The Audit Committee discussed with the independent registered public accounting firm the overall scope and plans for its audit. The Audit Committee meets with the independent registered public accounting firm, with and without management present, to discuss the results of their examination, their evaluation of Rhinebeck Bancorp’s internal controls, and the overall quality of its financial reporting.

In performing these functions, the Audit Committee acts only in an oversight capacity. In its oversight role, the Audit Committee relies on the work and assurances of Rhinebeck Bancorp’s management, which has the primary responsibility for financial statements and reports, and of the independent registered public accounting firm who, in its report, expresses an opinion on the conformity of Rhinebeck Bancorp’s consolidated financial statements to GAAP. The Audit Committee’s oversight does not provide it with an independent basis to determine that management has maintained appropriate accounting and financial reporting principles or policies, or appropriate internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the Audit Committee’s considerations and discussions with management and the independent registered public accounting firm do not assure that the financial statements are presented in accordance with GAAP, that the audit of the financial statements has been carried out in accordance with GAAP or that the independent registered public accounting firm is “independent.”

In reliance on the reviews and discussions referred to above, the Audit Committee has recommended to the Board of Directors, and the Board of Directors has approved, that the audited financial statements be included in Rhinebeck Bancorp’s Annual Report on Form 10-K for the year ended December 31, 2023 for filing with the Securities and Exchange Commission. The Audit Committee also has approved, subject to stockholder ratification, the selection of the independent registered public accounting firm for the year ending December 31, 2024.

Deferred Compensation Plan for Fees of Directors

Rhinebeck Bank maintains the Rhinebeck Savings Bank Deferred Compensation Plan for Fees of Directors. Each member of the Board of Directors of Rhinebeck Bank is eligible to participate in the plan and has the right to elect to defer the receipt of all or any part of the director fees earned, which are credited to a bookkeeping account established on behalf of each participant. Compensation credited to the participant’s bookkeeping account, including any interest earned thereon (which is credited on the last day of each plan year at rate determined by a resolution of the Board of Directors, which for 2023 was 5.91%) is payable upon the earlier of the participant’s death or separation from service from the board. Such deferred compensation will be payable in a lump sum, unless the participant has elected to be paid in monthly installments over a period of up to five years. As of December 31, 2023, there were four directors participating in the plan.

Employment Agreements

Michael J. Quinn and Jamie J. Bloom. Rhinebeck Bank maintains employment agreements with Mr. Quinn and Ms. Bloom. Each agreement extends automatically for one additional year on January 1 of each year so that the term will be three years from the renewal date, unless either Rhinebeck Bank or the executive gives notice no later than 90 days before such anniversary date that the agreement will not be renewed.

Each agreement specifies the executive’s base salary. The base salary will be reviewed at least annually and may be adjusted in the Board’s discretion. In addition to the base salary, each agreement provides that the executive will be eligible to participate in the short-term and long-term incentive compensation programs of Rhinebeck Bank and Rhinebeck Bancorp. Each agreement specifies the executive’s target bonus opportunity under the Rhinebeck Bank Executive Short-Term Incentive and Retention Plan (the “STIP”), which is 25% of base salary for Mr. Quinn and 20% of base salary for Ms. Bloom. The executives are also entitled to participate in all employee benefit plans, arrangements and perquisites offered to employees and officers of Rhinebeck Bank and the reimbursement of reasonable travel and other business expenses incurred in the performance of their duties with Rhinebeck Bank, including memberships in organizations as the executives and the Board mutually agree are necessary and appropriate. Mr. Quinn is reimbursed for the full cost of the use of an automobile. Ms. Bloom is entitled to be reimbursed for use of an automobile, up to a dollar amount that is mutually agreeable to Rhinebeck Bank and Ms. Bloom.

14

Rhinebeck Bank may terminate the executive’s employment or the executive may resign at any time with or without “good reason.” In the event of the executive’s termination without cause other than due to death or disability or voluntary resignation for good reason (a “qualifying termination event”), Rhinebeck Bank would pay a monthly severance payment equal to the sum of the executive’s base salary and average annual cash incentive compensation awarded under the STIP (or any other comparable cash incentive plan), which would include any portion of the award that is tax-deferred and payable pursuant to the Rhinebeck Executive Long-Term Incentive and Retention Plan (the “LTIP”), for the three most recent annual performance periods immediately prior to the executive’s date of termination, divided by 12. Such monthly severance payment would be paid for 36 months for Mr. Quinn and 24 months for Ms. Bloom. In addition, Mr. Quinn and Ms. Bloom would receive non-taxable medical and dental insurance coverage under Rhinebeck Bank’s group health plan at the same cost-sharing arrangement in effect as of the date of termination for the earlier of 36 months and 24 months, respectively, or, until the date the executive receives substantially comparable coverage from another employer. The executives would also be reimbursed for the reasonable cost of outplacement services, up to $5,000. “Good Reason” for purposes of the employment agreements means: a material reduction in base salary and/or incentive compensation opportunities; a material reduction in authority, duties or responsibilities associated with the executive’s position with Rhinebeck Bank; a relocation of the executive’s principal place of employment by more than 35 miles from Rhinebeck Bank’s main office; or a material breach of the agreements by Rhinebeck Bank.

In the event of the executive’s qualifying termination event on or within two years after a change in control of Rhinebeck Bancorp or Rhinebeck Bank, Mr. Quinn and Ms. Bloom would be entitled to (in lieu of the payments and benefits described in the previous paragraph) a severance payment equal to three times and two times, respectively, of the sum of the executive’s: (1) base salary; and (2) average bonus awarded under the STIP (or any other comparable cash incentive plan), which would include any portion of the award that is tax-deferred and payable pursuant to the LTIP, for the three most recent annual performance periods immediately prior to the change in control. Such payment will be payable in a lump sum within 30 days following the executive’s date of termination.

In addition, Rhinebeck Bank (or its successor) will continue to provide the executive with life insurance and non-taxable medical and dental insurance coverage substantially comparable to the coverage provided to the executive immediately before his or her date of termination at no cost to the executive. Such continued coverage will cease upon the earlier of: (1) three years for Mr. Quinn and two years for Ms. Bloom after the executive’s date of termination; (2) the date on which the executive becomes a full-time employee of another employer and receives comparable health and welfare benefits; or (3) the executive’s death.

The employment agreements would immediately terminate upon the executive’s death or disability. In the event of death, Rhinebeck Bank has no obligation to pay any additional severance benefits to the executives under the employment agreements. In the event of the executive’s disability, Rhinebeck Bank would provide continued base salary payments to Mr. Quinn and Ms. Bloom for 36 months and 24 months, respectively, provided that such payment would be reduced by the amount of any disability insurance benefits payable to the executive during such period under Rhinebeck Bank’s disability insurance plan or program.

Upon termination of employment (other than a termination in connection with a change in control), each executive will be required to adhere to one-year non-competition and non-solicitation restrictions.

Michael J. McDermott. Rhinebeck Bank also maintains an employment agreement with Mr. McDermott. The term of the agreement is indefinite and will continue until Mr. McDermott’s employment relationship with Rhinebeck Bank ceases. Mr. McDermott has announced his retirement effective May 31, 2024.

The agreement specifies Mr. McDermott’s base salary, which may be increased from time to time by the Board of Directors. In addition, the agreement provides that Mr. McDermott will be eligible to participate in STIP. Mr. McDermott is also entitled to participate in all employee benefit plans or benefits made available to Rhinebeck Bank similarly situated executives and the reimbursement of ordinary and necessary business expenses incurred in connection with performance of his duties with Rhinebeck Bank. In the event of a termination without cause, other than due to death or disability, or “constructive termination,” and so long as Mr. McDermott executes a Separation Agreement and Release, Rhinebeck Bank would be required to pay him a severance payment equal to one year of his base salary at the annual rate in effect immediately prior to his date of termination, and an amount equal to the latest bonus payment made to him in the year prior to which his employment is terminated. Such payments would be made over a period of 12 months, at the same time and in the same manner as Rhinebeck Bank pays base salary to executives. In addition, Rhinebeck Bank would be required to provide for Mr. McDermott’s continued coverage under all health benefit plans or arrangements in which he was entitled to participate prior to his termination, or arrange to provide him with substantially similar benefits, for the earlier of (1) a period of 12 months, (2) until his death, or (3) until he is afforded a comparable benefit at a comparable cost by a subsequent employer. Rhinebeck Bank also would be required to pay or reimburse Mr. McDermott for outplacement services, up to $5,000. A “constructive termination” for purposes of the employment agreement means: a reduction in base salary; a material reduction in incentive compensation opportunities; the failure of Rhinebeck Bank to maintain a relative level of coverage under benefit plans, policies and practices or arrangements provided to other employees of the same or lesser levels of responsibilities; a

15

material diminution of responsibilities, status, title or office; or the failure of Rhinebeck Bank to pay any material amount of compensation, within 10 days after a written demand for such amount.

In the event Mr. McDermott’s employment terminates after a “change in control,” he would receive the amounts payable in the case of a termination without cause or a constructive termination, but they would become payable in a single lump sum within 30 business days following his termination (the “change in control payment”). The change in control payment would be reduced to avoid penalties under Section 280G of the Internal Revenue Code if the change in control payment, plus any other payment or benefit payable to Mr. McDermott under any other agreement or plan of Rhinebeck Bank do not, in the aggregate (collectively, referred to as the “total payment”) exceed 115% of the maximum amount that could be paid without triggering such penalties. Conversely, if the total payment is greater than or equal to 115% of the maximum amount that could be paid to Mr. McDermott without triggering penalties under Section 280G of the Internal Revenue Code, Mr. McDermott would receive a gross-up payment to compensate him for any excise taxes owed under Section 4999 of the Internal Revenue Code.

The employment agreement would immediately terminate upon Mr. McDermott’s death, with no additional severance benefits. In the event of termination due to total disability (rendering Mr. McDermott incapable of performing his usual and customary duties), Rhinebeck Bank would be required to pay Mr. McDermott an amount equal to 12 months of his base salary, at the rate in effect as of the date he became totally disabled, reduced by the amount of disability insurance benefits payable to him during such period under any employer-paid disability insurance plan. Such payments would be made at the same time and in the same manner as such compensation would have been paid if he had remained in active employment during the 12-month period.

Upon termination of employment, Mr. McDermott would be required to adhere to one-year non-competition and non-solicitation restrictions set forth in his employment agreement.

Executive Short-Term Incentive and Retention Plan (STIP)

Rhinebeck Bank adopted the STIP for its executive officers, including the named executive officers. The STIP is designed to: (1) support a business change to community-based banking; (2) support a culture change to pay-for-performance; (3) focus the executive team on annual goals to meet long-term goals; (4) reward executives for their contributions; and (5) align compensation with the goals of the organization and marketplace practices. The plan provides annual incentive awards to participants based on bank-wide, department and/or individual performance goals as established annually by the Compensation Committee, with input from the Chief Executive Officer, which is determined by using performance history, peer data, market data and the Compensation Committee’s judgment based on previous experience and projected market conditions.

The named executive officers can achieve annual incentive awards based on a percentage of salary, depending on whether the performance goals are achieved at minimum, target or maximum levels, and each goal is weighted between bank-level goals and individual goals. The annual performance period under the STIP is measured over a calendar year (the “plan year”). For the 2023 plan year, the performance goals established were based on Rhinebeck Bank’s business plan. Furthermore, any annual incentive award payable under the STIP was contingent upon Rhinebeck Bank achieving certain minimum performance goals. The named executive officer’s annual incentive award opportunities for the 2023 plan year, as a percentage of base salary, were as follows:

Unless otherwise deferred as described below, the executive’s annual incentive award is payable in a cash lump sum as soon as practicable following the completion of the plan year, provided, however, that such payment will be made no later than two and one-half months following the end of the plan year.

The STIP provides that the Compensation Committee may elect for a percentage of the executive’s annual incentive award to be deferred and paid on a later date (the “deferred bonus”), provided that such election is made prior to the applicable plan year associated with the annual incentive award. Any deferred bonus amount would be credited to an incentive benefit account established for the executive under the LTIP, and the time and manner of payment of the deferred bonus would be determined in accordance with the LTIP. For 2023, 40% of the annual incentive awards payable to Mr. Quinn, Ms. Bloom and Mr. McDermott was designated as a

16

deferred bonus and was credited to their incentive benefit accounts. Based on the foregoing, Mr. Quinn, Ms. Bloom and Mr. McDermott earned the following annual incentive awards under the STIP for 2023:

Officer	Annual Incentive Award Paid Immediately		Deferred Bonus Credited to LTIP		Total Annual Incentive Award Earned
Michael J. Quinn	$	13,039	$	8,692	$	21,731
Jamie J. Bloom		6,784		4,523		11,307
Michael J. McDermott		5,178		3,452		8,630

Executive Long-Term Incentive and Retention Plan (LTIP)

Rhinebeck Bank adopted the LTIP as a companion benefit plan with the STIP. Any executive participating in the STIP who receives a deferred bonus is a participant in the LTIP. Rhinebeck Bank maintains an incentive benefit account, which is a bookkeeping account established on behalf of each participant in the LTIP. Each participant’s deferred bonus payable pursuant to the STIP is credited to his or her incentive benefit account as of the date on which the participant’s annual incentive award is payable under the STIP. As of the last day of each plan year, Rhinebeck Bank will credit to each participant’s incentive benefit account interest earned on the account balance, based on a percentage equal to Rhinebeck Bancorp’s return on equity (on a consolidated basis) for its fiscal year immediately preceding the applicable plan year.

The participant will vest in each deferred bonus credited to his or her incentive benefit account at a rate of 20% per year for each year of service with Rhinebeck Bank, commencing on January 1^st of the year immediately following the plan year. Notwithstanding the foregoing, the participant becomes 100% vested in the deferred bonus upon the earlier of: (1) the participant’s death, disability or involuntary termination without “cause”; (2) the participant’s attainment of either age 65 or age 55 with 15 years of service while employed with Rhinebeck Bank; or (3) a change in control of Rhinebeck Bancorp or Rhinebeck Bank.

Upon the participant’s termination of employment for any reason other than for cause, the vested portion of the participant’s incentive benefit account balance would be payable in a cash lump sum within 30 days following the participant’s date of termination.

Supplemental Executive Retirement Agreement

Rhinebeck Bank maintains a supplemental executive retirement agreement with Mr. Quinn (the “SERP”). The SERP is designed to provide non-qualified supplemental retirement income to Mr. Quinn as an incentive and reward for his continued service with Rhinebeck Bank. Upon the earlier of Mr. Quinn’s: (1) attainment of age 65; or (2) disability, he would be entitled to an annual benefit of $108,000, payable in monthly installments for 20 years (the “normal retirement benefit”). Payment of the normal retirement benefit would commence on the last day of the month following Mr. Quinn attaining age 65. Upon Mr. Quinn’s termination of employment for any reason other than cause or disability, prior to attaining age 65, he would be entitled to a reduced annual benefit, payable in monthly installments for 20 years, commencing on the last day of the month following Mr. Quinn attaining age 65. If Mr. Quinn’s separation from service occurs within 24 months of a change in control of Rhinebeck Bank, he would be entitled to the actuarial equivalent of the normal retirement benefit payable at age 65, determined as of the end of the year immediately prior to the date of separation from service (the “change in control benefit”). The change in control benefit would commence on the last day of the month following Mr. Quinn’s separation from service and would be payable in equal monthly installments for 20 years.

If Mr. Quinn dies while employed with Rhinebeck Bank, his beneficiary would be entitled to a lump sum payment equal to $2.16 million, which would be paid in lieu of the benefits described above.

Split Dollar Insurance Plan

Rhinebeck Bank maintains the Rhinebeck Bank Split Dollar Insurance Plan. Employees selected by the Board of Directors of Rhinebeck Bank are eligible to participate in the plan. Each named executive officer is participating in the plan. The plan provides that each participant is entitled to share in the proceeds under a life insurance policy owned by Rhinebeck Bank if a participant dies while employed with Rhinebeck Bank. The death benefit payable to the participant’s designated beneficiary is equal to the lesser of: (1) two times executive’s base salary less any benefits paid to the participant pursuant to Rhinebeck Bank’s group life insurance plan; or (2) the net death proceeds, which is the total death proceeds of the participant’s life insurance policy under the plan minus the greater of: (x) the cash surrender value or (y) aggregate premiums paid with respect to the policy. Upon the participant’s termination of employment, the participant’s designated beneficiary will not be entitled to any death benefit under the plan.

2020 Equity Incentive Plan

On May 26, 2020, Rhinebeck Bancorp’s stockholders approved the Rhinebeck Bancorp, Inc. 2020 Equity Incentive Plan (the “2020 Equity Incentive Plan”), which provides for the grant of stock-based awards to our directors and employees. The 2020 Equity Incentive Plan authorizes the issuance or delivery to participants of up to 763,743 shares of Rhinebeck Bancorp common stock pursuant to grants of incentive and non-qualified stock options, restricted stock awards and restricted stock units. Of this number, the

17

maximum number of shares of Rhinebeck Bancorp common stock that may be issued under the 2020 Equity Incentive Plan pursuant to the exercise of stock options is 545,531, and the maximum number of shares of Rhinebeck Bancorp common stock that may be issued as restricted stock awards or restricted stock units is 218,212. All grants will be subject to conditions established by the Board of Directors that are set forth in the applicable award agreement, including vesting conditions. The exercise price of stock options granted under the 2020 Equity Incentive Plan may not be less than the fair market value on the date the stock option is granted.

OTHER INFORMATION RELATING TO DIRECTORS AND EXECUTIVE OFFICERS

Transactions with Related Persons

The federal securities laws generally prohibit publicly traded companies from making loans to their executive officers and directors, but it contains a specific exemption from such prohibition for loans made by federally insured financial institutions, such as Rhinebeck Bank, to their executive officers and directors in compliance with federal banking regulations. Federal regulations permit executive officers and directors to receive the same terms that are available to other employees as long as the director or executive officer is not given preferential treatment compared to the other participating employees. At December 31, 2023, all of our loans to directors and executive officers were made in the ordinary course of business, were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to Rhinebeck Bancorp or Rhinebeck Bank, and did not involve more than the normal risk of collectability or present other unfavorable features. These loans were performing according to their original repayment terms at December 31, 2023, and were made in compliance with federal banking regulations.
