Dear Fellow Shareholders:

The 2024 Annual Meeting of Shareholders of Middlefield Banc Corp. will be held on Wednesday, May 15, 2024 at 1:00 p.m. Eastern Time. We have adopted a virtual format for our Annual Meeting. We will provide a live webcast of the Annual Meeting at www.meetnow.global/MFDL4CJ where you will be able to vote electronically and submit questions during the meeting. There will be no physical location for the meeting.

The three items to be considered at the meeting involve the election of directors, a non-binding “say-on-pay” vote concerning the company’s executive compensation programs, and a non-binding vote on the ratification of the appointment of auditors.

Your vote on these matters is important, regardless of the number of shares you own, and all shareholders are encouraged to participate in the live webcast of the Annual Meeting. However, it is important that your shares be represented regardless of whether you plan to participate in the live webcast of the Annual Meeting. In order to ensure that your shares are represented, I urge you to go to www.investorvote.com/MBCN and log in to vote by entering the 15-digit code found on the enclosed proxy card or, if you hold your shares in a brokerage account, by following the voting instructions of your bank or broker. You may also execute and return the enclosed proxy card or submit your proxy by telephone.

Sincerely,

How to Register to Attend the Virtual Annual Meeting. If you are a registered shareholder (i.e., you hold shares as reflected by the records of our transfer agent), you do not need to register to attend the virtual Annual Meeting. Please follow the instructions on the proxy card that you received.

If you hold your shares through an intermediary, such as a bank, broker or other shareholder of record, you must register in advance to attend the virtual Annual Meeting. To register to attend the Annual Meeting online by webcast, you must submit proof of your proxy power (legal proxy) reflecting your Middlefield holdings along with your name and email address to our transfer agent, Computershare.

Requests for registration should be directed to Computershare by forwarding the email you received from your bank, broker or other shareholder of record, or an image of your legal proxy, to legalproxy@computershare.com. Requests for registration must be labeled as “Legal Proxy” and be received no later than 5:00 p.m., Eastern Time, on May 10, 2024. You will receive a confirmation of your registration by email after your registration materials have been received.

Voting Procedures. If you were a shareholder of record at the close of business on March 15, 2024, you are entitled to vote at the Annual Meeting. As of March 15, 2024, there were 8,067,144 shares of Middlefield common stock outstanding.

The enclosed proxy is for use if you are unable to participate in the live webcast of the Annual Meeting or if you wish to have your shares voted by proxy even if you participate in the live webcast of the Annual Meeting. We will provide a live webcast of the Annual Meeting at www.meetnow.global/MFDL4CJ where you will be able to vote electronically. Please vote your shares by (1) the internet, (2) telephone or (3) completing, signing, dating, and returning the enclosed proxy as soon as possible in the postage-paid envelope provided. If you hold your shares in the name of a bank, broker or other shareholder of record, the availability of internet and telephonic voting will depend on the voting processes of the bank, broker or other shareholder of record.

Proxies solicited hereby may only be used at the Annual Meeting and any adjournment thereof, and will not be used for any other meeting. Proxies solicited by the board will be voted in accordance with the directions given. If no instructions are given, proxies will be voted in favor of the proposals set forth in this proxy statement.

If your shares are registered directly in your name with our transfer agent, you are a “shareholder of record” or registered holder. If your shares are held through a bank, broker or other shareholder of record, you are considered the “beneficial owner” of those shares. If your shares are held by a bank, broker or other shareholder of record, that entity or person will provide separate voting instructions. If you as beneficial owner provide specific voting instructions to your bank, broker or other shareholder of record by mail, telephone, or internet, your bank, broker or other shareholder of record will vote your shares as you have directed.

Revocation of Proxies. Shareholders who execute proxies retain the right to revoke them at any time before completion of the Annual Meeting, but revocation will not affect a vote previously taken. If your common stock is held in street name, you must follow the instructions of your bank, broker or other shareholder of record to revoke your proxy instructions. If you are a holder of record and wish to revoke your proxy instructions, you may revoke a proxy by:

● participating in the live webcast of the Annual Meeting at www.meetnow.global/MFDL4CJ where you will be able to vote electronically (Simply attending the virtual Annual Meeting without voting will not revoke an earlier proxy),

● giving a subsequent proxy relating to the same shares,

● casting a later internet or telephone vote relating to the same shares, or

● filing with the Secretary at or before the Annual Meeting a written revocation notice bearing a later date than the proxy.

A written notice revoking a proxy should be delivered to Ms. Julie E. Shaw, Secretary, Middlefield Banc Corp., 15985 East High Street, P.O. Box 35, Middlefield, Ohio 44062. Unless revoked, the shares represented by proxies will be voted at the Annual Meeting.

Expense of Soliciting Proxies. Middlefield will bear the cost of soliciting proxies. In addition to solicitation by mail, directors, officers, and employees of Middlefield and its subsidiaries may solicit proxies personally or by telephone, but they will receive no additional compensation for doing so.

Middlefield will pay the standard charges and expenses of brokerage houses, voting trustees, banks, associations, and other custodians, nominees, and fiduciaries who are record holders of Middlefield common stock not beneficially owned by them for forwarding this proxy statement and other proxy solicitation materials to and obtaining proxies from the beneficial owners of Middlefield common stock.

Quorum and Vote Required. A quorum will exist at Middlefield’s Annual Meeting if a majority of the outstanding common stock is represented in person or by proxy. A quorum must be present in person or by proxy at the meeting before any action other than adjournment can be taken. A properly executed proxy card marked “ABSTAIN” will be counted for purposes of determining whether a quorum is present.

Shareholders are entitled to one vote for each share held. Shareholders are not entitled to cumulate their votes in the election or removal of directors or otherwise. Our Regulations provide in Article III, section 2 that directors are elected by a plurality vote of votes cast, meaning the nominees receiving the greatest numbers of votes will be elected. Our Regulations provide in Article I, section 7 that a majority of votes cast is sufficient to constitute the act of shareholders, except as otherwise expressly required by law, our Articles of Incorporation or the Regulations. We will consider the non-binding proposal to approve the compensation of Middlefield’s named executive officers (“say-on-pay”) to be approved if the proposal receives the affirmative vote of a majority of the votes cast on the proposal. We will consider the proposal to ratify the appointment of S.R. Snodgrass, P.C. as independent auditor to be approved if the proposal receives the affirmative vote of a majority of the votes cast on the proposal.

Abstentions and Broker Non-Votes. Abstention may be specified on all proposals except the election of directors. Abstentions and broker non-votes will be counted for purposes of establishing that a quorum is present at the meeting. A broker non-vote arises when shares held by a broker nominee for a beneficial owner are not voted because the broker nominee does not receive voting instructions from the broker’s customer for non-routine proposals and lacks discretionary authority to vote the shares without instructions.

Brokers normally have authority to vote on routine matters, such as the ratification of independent registered public accounting firms, but not on non-routine matters such as the election of directors. Proposal 3, the proposal to ratify the appointment of S.R. Snodgrass, P.C. as independent auditor, is the only routine matter to be voted upon at the Annual Meeting.

The election of directors and the advisory vote on executive compensation are not considered routine matters, and therefore broker non-votes may exist in connection with these proposals. We urge you to provide instructions to your broker or nominee so that your vote may be counted on these important matters. Brokers are not allowed to vote uninstructed shares in regard to the election of directors and the advisory approval of Middlefield’s executive compensation. You should direct the vote of your shares by following the instructions provided on the voting instructions card you receive from your broker and return the voting instructions card to your broker in a timely manner to ensure that your shares are voted on your behalf.

Board Recommendations. The board of directors recommends that you vote FOR election of the director nominees identified in this proxy statement, FOR the say-on-pay proposal, and FOR ratification of the appointment of S.R. Snodgrass, P.C. as auditor for the fiscal year ending December 31, 2024.

CORPORATE GOVERNANCE

Director Independence. A majority of Middlefield’s directors are independent, as the term independence is defined in Rule 5605(a)(2) of the NASDAQ Stock Market listing rules and as defined by Rule 10A-3(b)(1)(ii) of the SEC. The board has determined that all of the current directors other than Mr. Zimmerly are independent directors, including all directors serving on the Corporate Governance and Nominating Committee, the Audit Committee, and the Compensation Committee. In determining independence, the board of directors considers loan and deposit relationships with each director or with persons related to or affiliated with the director. The NASDAQ Stock Market listing rules do not disqualify a director from being deemed independent based on loan and deposit relationships.

Leadership Structure of the Board. The office of Chairman of the Board and the position of Chief Executive Officer have traditionally been separated at Middlefield. Middlefield believes that separation of these two offices is consistent

3 

with the board’s responsibility for oversight of management and of Middlefield’s affairs generally. The time, effort, and energy that the Chief Executive Officer must devote to that position, as well as the commitment required to serve as Chairman of the Board, make it impractical for one person to serve in both roles. The board believes that an independent director serving as Middlefield’s Chairman of the Board is the appropriate leadership structure at this time, demonstrating Middlefield’s commitment to good corporate governance.

Risk Oversight. The board is actively involved in oversight of the risks that could affect Middlefield. The board’s oversight is conducted primarily through committees, but the full board retains responsibility for general oversight of risks. Board committees exercising oversight of risks include (1) an Audit Committee that oversees financial reporting and legal and compliance risks, (2) a Compensation Committee that is responsible for risks relating to Middlefield’s employment policies and compensation and benefits systems, (3) a Corporate Governance and Nominating Committee that oversees risks relating to management and board succession planning, Middlefield’s ethics and business practices, and the Company’s corporate social responsibility and (4) other bank committees, such as the loan and asset/liability management committees, that are responsible for exercising oversight of the risks associated with the business of banking. The board satisfies its risk oversight responsibility through full reports by each committee chair regarding the committee’s considerations and actions, as well as through regular reports directly from officers responsible for oversight of particular risks within Middlefield and The Middlefield Banking Company.

The board recognizes that management succession planning is an ongoing part of its responsibilities. The full board is responsible for overseeing CEO succession planning and assesses both expected and emergency CEO succession at least annually. The board regularly works with its committees and members of management to evaluate potential successors to the CEO. The board discusses potential successors with the CEO and together with the CEO reviews any development plans recommended for such individuals. A similar process is also followed with regard to the other executive officers.

Code of Ethics. Our Code of Ethics requires that directors, executive officers, and employees avoid conflicts of interest, comply with all laws and other legal requirements, conduct business in an honest and ethical manner, and otherwise act with integrity and in Middlefield’s best interests. Directors, executive officers, and employees must report any conduct they believe in good faith to be an actual or apparent violation of the Code of Ethics. Middlefield’s Code of Ethics includes a Code of Ethics for Financial Professionals, which applies to the principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. The goal of the Code of Ethics for Financial Professionals is to promote integrity in the preparation and reporting of financial information and to assure full, fair, accurate, timely, and understandable disclosure in SEC reports and other public communications. The Code of Ethics is available at www.middlefieldbank.bank.

Anti-Hedging Policy. Middlefield’s Insider Trading Policy prohibits hedging transactions involving Middlefield’s securities by directors, executive officers and employees of Middlefield or The Middlefield Banking Company. The anti-hedging policy: (i) requires that Middlefield securities purchased by a director, officer or employee in the open market must be held for a minimum of six months and preferably longer; (ii) prohibits direct and indirect short selling of Middlefield securities by directors, officers or employees; (iii) prohibits transactions by directors, officers or employees in puts, calls or other derivative transactions involving Middlefield’s securities, other than the exercise of options issued by Middlefield to its employees or directors; and (iv) prohibits other forms of hedging or monetarization transactions by directors, officers or employees, such as zero-cost collars and forward sales transactions, involving Middlefield’s securities.

Margin Accounts and Pledged Securities. Directors, officers and other employees are prohibited from holding Middlefield securities in a margin account or otherwise pledging Middlefield shares as collateral for a loan or other financial obligation.

Shareholder Communications. A shareholder who wishes to communicate with the board or with individual directors concerning Middlefield’s financial statements, accounting practices, or internal controls should write to the chairman of the Audit Committee in care of Ms. Julie E. Shaw, Secretary, at Middlefield Banc Corp., 15985 East High Street, P.O. Box 35, Middlefield, Ohio 44062. If the shareholder’s concern relates to Middlefield’s governance practices, business ethics, or corporate conduct, the concern should be submitted in writing to the chairman of the Corporate Governance and Nominating Committee in care of Ms. Julie E. Shaw, Secretary, at the preceding address. Other concerns may be submitted to any of the independent directors at that address.

Board Meetings and Committees. Middlefield’s board held nine meetings in 2023. With the exception of director Watkins, who attended 62.5% of the meetings, each individual who served in 2023 as a director of Middlefield attended at least

4 

75% of the sum of the total number of board meetings and the total number of meetings held by all committees on which he or she served during the tenure of his or her service. The board encourages directors to attend the annual meeting of shareholders. Nine of Middlefield’s twelve directors attended the 2023 annual shareholder meeting. Directors serving on the Audit Committee, the Corporate Governance and Nominating Committee, the Compensation Committee, and the Executive Committee are –

¹ Mr. Voinovich became Committee Chairman on May 10, 2023.

² Ceased to be Committee Chairman on May 10, 2023.

³ Committee Chairman

Audit Committee. The Audit Committee appoints Middlefield’s independent public auditor, reviews and approves the audit plan and fee estimate of the independent public auditor, appraises the effectiveness of the internal and external audit efforts, evaluates the adequacy and effectiveness of accounting policies and financial and accounting management, supervises the internal auditor, and reviews and approves the annual financial statements. On an annual basis, the Audit Committee evaluates the qualifications, performance, tenure and independence of S.R. Snodgrass, P.C. and determines, after also considering the impact of a change in Middlefield’ s independent registered public accounting firm, whether to re-engage S.R. Snodgrass, P.C. S.R. Snodgrass, P.C., together with its predecessors, has served as Middlefield’s independent registered public accounting firm since 1986. S.R. Snodgrass, P.C. rotates its lead audit engagement partner every five years and the Audit Committee takes a lead role in the process of evaluating and selecting the new lead audit engagement partner. The Audit Committee believes there are benefits to having an independent registered public accounting firm with an extensive history with Middlefield, including higher quality audit work and accounting advice due to S.R. Snodgrass, P.C.’s institutional knowledge of Middlefield’s business and operations, accounting policies and financial systems, and internal control framework, as well as operational efficiencies. S.R. Snodgrass, P.C. is subject to independence controls that mitigate the risks that may be associated with long auditor tenure.

The Audit Committee has the authority to engage separate legal counsel and other advisors, as necessary, to execute its duties. The Audit Committee met five times in 2023. A copy of the Audit Committee charter is available at www.middlefieldbank.bank. A copy of the charter is also available in print to shareholders upon request, addressed to Ms. Julie E. Shaw, Secretary, at Middlefield Banc Corp., 15985 East High Street, P.O. Box 35, Middlefield, Ohio 44062.

Middlefield believes that the directors serving on the Audit Committee do not have a relationship with Middlefield or its subsidiaries that would interfere with the exercise of independent judgment as directors. The board believes that all members of the Audit Committee satisfy the current independence requirements of the NASDAQ Stock Market and applicable rules and regulations of the SEC, and that Director Jones and Director Turk are audit committee financial experts, as that term is defined in SEC rules.

Audit Committee Report. The Audit Committee reviewed and discussed the audited financial statements for the year ended December 31, 2023 and discussed the audited financial statements with management. The Audit Committee has also discussed with S.R. Snodgrass, P.C., Middlefield’s independent auditor, the matters required to be discussed by PCAOB Auditing Standard No. 1301 (Communication with Audit Committees). The Audit Committee received the written disclosures and the letter from S.R. Snodgrass, P.C. required by PCAOB Rule 3526 (Communications with Audit Committees Concerning Independence), and discussed with S.R. Snodgrass, P.C. its independence. Based on this, the Audit Committee recommended to the board that the audited financial statements be included in Middlefield’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 for filing with the SEC.

Submitted by the Audit Committee:

Kevin A. DiGeronimo, Kenneth E. Jones, Darryl E. Mast, Carolyn J. Turk, and Mark R. Watkins.

Compensation Committee. The Compensation Committee establishes the base salary of each executive officer other than the Chief Executive Officer and makes recommendations for the Chief Executive Officer’s compensation to the full board. The Middlefield Banking Company’s Compensation Committee establishes the executives’ award levels under the Annual Incentive Plan and administers the executive variable benefit deferred compensation agreements and supplemental executive retirement plans maintained by The Middlefield Banking Company. Middlefield’s Compensation Committee is responsible for administration of other executive benefits and plans including the 2017 Omnibus Equity Plan. The Compensation Committee’s performance review of the Chief Executive Officer takes into account reports submitted by each director. Performance reviews of other executives are the primary responsibility of the Chief Executive Officer. The Compensation Committee met six times in 2023. A copy of the Compensation Committee charter is available at www.middlefieldbank.bank. A copy of the charter is also available in print to shareholders upon request, addressed to Ms. Julie E. Shaw, Secretary, at Middlefield Banc Corp., 15985 East High Street, P.O. Box 35, Middlefield, Ohio 44062.

The Compensation Committee has sought input on both board and executive compensation issues from compensation consultants. The committee sometimes engages consultants to conduct periodic comprehensive total compensation studies or to advise about compensation practices generally. The Compensation Committee retains the right to hire, fire, and obtain advice and assistance from legal counsel or other experts or consultants, consistent with its charter. In 2023, Newcleus Compensation Advisors reviewed Middlefield’s management compensation practices and provided surveys of management compensation practices for a peer group of financial institutions.

Total compensation for the named executive officers is comprised of base salaries, annual cash incentive awards, retirement plan contributions, equity awards and other benefits and perquisites. To determine compensation levels for the named executive officers, as well as other officers, the Compensation Committee reviews compensation survey data from independent sources to ensure that the total compensation program is competitive. In making determinations on the mix and amount of executive compensation, the Compensation Committee reviews all components of executive compensation for each executive. The Compensation Committee has no mandatory policy for the allocation among base salary, short-term performance-based cash bonuses, long-term incentives, and retirement benefits. The Compensation Committee considers Middlefield’s performance, industry comparative data, experience, tenure, and responsibilities in recommending compensation for each position. Executive and officer compensation is weighted toward Middlefield’s performance and achievement of annual and long-term objectives. In general, Middlefield attempts to target total compensation for named executive officers at market competitive levels of peer financial companies.

The Compensation Committee and the compensation consultant evaluate Middlefield pay practices for the named executive officers with comparison to similarly situated banking organizations. Based on Newcleus Compensation Advisors’ survey delivered to Middlefield, the peer group most recently reviewed by the Compensation Committee included the following similarly situated banking organizations.

Regional Peer Group
BankFinancial Corporation Citizens & Northern Corporation Citizens Financial Services, Inc. Civista Bancshares, Inc. CSB Bancorp, Inc. Emclaire Financial Corp. Farmers National Banc Corp. Farmers & Merchants Bancorp, Inc. First Financial Corporation	First Savings Financial Group, Inc. HBT Financial, Inc. LCNB Corp. Ohio Valley Banc Corp. Orrstown Financial Services, Inc. Penns Woods Bancorp, Inc. Richmond Mutual Bancorporation, Inc. SB Financial Group, Inc.

Located in Illinois, Indiana, Ohio, and Pennsylvania, the peer group is comprised of 17 banking organizations reporting assets between $1 billion and $5 billion as of the third quarter of 2022. The executive compensation information for the peer banks was reported in 2022 proxy statements. The peer financial institutions were publicly traded holding companies that ranged in size from approximately 57% of Middlefield’s asset size to approximately 279% of Middlefield’s asset size.

Corporate Governance and Nominating Committee. The Corporate Governance and Nominating Committee recommends to the board the slate of director nominees to be proposed by the board for election by the shareholders, any

6 

director nominees to be elected by the board to fill interim director vacancies, and the directors to be selected for membership on and chairmanship of the committees of the board. In addition, the committee considers general corporate governance matters on behalf of the board and annually reviews with the board the requisite skills and criteria for new members. The committee also reviews the composition and function of the board as a whole and is responsible for assisting the board in overseeing Middlefield’s practices and reporting with respect to corporate social responsibility. The committee met four times in 2023.

To identify nominees, the committee relies on personal contacts as well as its knowledge of members of the local communities. The committee maintains a commitment to diversity (including age, gender, race, ethnicity, and experience) with respect to the identification of potential candidates for board membership. When seeking potential candidates for directorship, the committee will include highly qualified candidates who reflect diverse backgrounds (including diversity of gender, race and ethnicity) in the initial pool from which nominees are chosen. In its deliberations, the committee takes into account all facets of a potential nominee’s background, including the following –

● personal qualities and characteristics,

● accomplishments and reputation in the business community,

● financial, regulatory, and business experience,

● current knowledge and contacts in the communities in which Middlefield does business,

● ability and willingness to commit adequate time to board and committee matters,

● fit of the individual’s skills with those of other directors and potential directors in building a board that is effective and responsive to Middlefield’s needs, independence, and

● any other factors the board deems relevant, including diversity of viewpoints, background, experience, and other demographics.

The committee also considers and reviews the director’s board and committee attendance and performance, length of board service, experience, skills, the contributions that the director brings to the board, and independence. The committee’s goal is to identify individuals who will enhance and add valuable perspective to the board’s deliberations and who will assist Middlefield in its efforts to capitalize on business opportunities in a challenging and highly competitive market.

A copy of the Corporate Governance and Nominating Committee charter is available at www.middlefieldbank.bank, along with a copy of our Corporate Governance Guidelines. The charter and guidelines are also available in print to shareholders upon request, addressed to Ms. Julie E. Shaw, Secretary, at Middlefield Banc Corp., 15985 East High Street, P.O. Box 35, Middlefield, Ohio 44062.

The committee will consider director nominees recommended by shareholders. A shareholder may submit a nomination for director by following the procedures specified in Article III, section 4, of Middlefield’s Regulations.

Middlefield’s Corporate Governance Guidelines provide that upon attaining age 75 a director may complete his or her term but may not stand for election to an additional term.

The Board’s Corporate Governance and Nominating Committee provides oversight of Middlefield’s practices and reporting with respect to corporate social responsibility considerations and risks. In 2023, we continued to build upon and improve our corporate social responsibility framework. Our executive management team and the Board recognize the importance of these responsibilities. Our corporate social responsibility areas of focus are organized around our communities, our customers, and our employees.

Sustainability. Middlefield takes steps to reduce our carbon footprint across all aspects of our operations and service delivery channels. We have expanded our technology to significantly reduce paper usage and waste by introducing mobile banking, e-signatures, electronic documents for loan applications, account openings, and paperless statements as well as leveraging digital technology for our internal documentation. As of December 31, 2023, Middlefield had 6,418 electronic banking users, 3,279 electronic bill-pay users, and 14,568 customers receiving electronic statements.

Middlefield has also increased its use of digital media and video conferencing to reduce employee travel between locations. Middlefield also continues to evaluate our overall office space needs. New branches are constructed using a smaller floor plan and motion sensor lighting to reduce energy consumption. Middlefield continues to develop technology-based solutions for our customers and our employees.

In the past several years Middlefield has taken steps to improve energy efficiency by installing LED lighting to reduce energy usage by over 50% for lighting, installing new roofs on 4 branches to reduce energy lost through heat conduction, replacing outdated HVAC systems to improve heating and cooling efficiency, eliminating in-house courier services to reduce transportation emissions, replacing traditional thermostats with scheduling thermostats to allow for reduced energy consumption when facilities are unoccupied, and replacing water coolers to eliminate the use of disposable water filters. Middlefield will continue to seek innovative ways to reduce its carbon footprint.

Social Responsibility. Middlefield has always been a strong supporter of the communities in which we work and live. Last year, Middlefield made more than $300,000 in community development grants and donations to non-profits and community organizations throughout Middlefield’s footprint, including United Way, local school districts and Chambers of Commerce, and financial literacy programs. Along with financial support, Middlefield executives served on committees and boards in several organizations including the United Way and Junior Achievement. Additionally, our employees gave generously of their time and money working on community service projects throughout the year and donating to local charities. Middlefield launched a company-wide United Way campaign which generated $20,000 in employee contributions. In addition to financial support, employees are encouraged to engage with local non-profits as volunteers and board members. In 2023, Middlefield employees contributed over 350 hours in volunteer service hours to community non-profit organizations.

Middlefield has also been a strong supporter of Community Reinvestment Act qualified community development purpose organizations and programs that support low to moderate-income communities. During 2023, Middlefield made $29.6 million in community development loans to support community revitalization and job creation, made numerous community development donations to support needs in the areas of food, shelter, essential services, school supplies, and financial literacy, made 20 grants totaling $166,000 for homebuyer assistance programs, and made a $2 million investment supporting Section 8 housing.

Customers. Loan and deposit products have been developed to aid consumers that fall within the low to moderate-income range. On the deposit side, we offer Clean Slate Checking accounts to help unbanked persons in the low- and moderate-income range to establish a banking relationship. In addition, deposit products have also been specifically created to serve small businesses and non-profit organizations. The Middlefield Banking Company also participates in the Small Business Administration loan program.

Stock Ownership Guidelines. Middlefield’s Corporate Governance Guidelines include stock ownership guidelines for directors. Since August 10, 2020, the guidelines provide that within four years after election a director should own Middlefield common stock equal in value to at least four times the director’s yearly base compensation for service as a director of The Middlefield Banking Company. After satisfying the minimum director share ownership requirements, the guidelines require a director to continue to maintain and hold that amount until he or she leaves the board. Yearly base compensation refers to the sum of the monthly cash retainer payments that directors of The Middlefield Banking Company receive for director service to the bank and the equity grants a director of The Middlefield Banking Company receives for the year. As of March 15, 2024, directors who have served for at least four years met the stock ownership guidelines.

As part of the Company’s Corporate Governance Guidelines, we have adopted stock ownership guidelines for our executive officers which require that individuals who currently hold the positions of Chief Executive Officer, President, Chief Operating Officer, and Chief Financial Officer must own shares of Middlefield’s common stock equal in value to one times the base annual salary for the position. Anyone named to any of those positions after January 1, 2023, will have three full years from the date of taking office to meet the stock ownership requirement. Once an individual has met the stock ownership requirement, the number of shares required to be owned will not change because of fluctuations in the share price of Middlefield stock.

11 

Delinquent Section 16(a) Reports. Section 16(a) of the Exchange Act requires that directors and executive officers file with the SEC initial reports of ownership and reports of changes in ownership. Based solely on review of the copies of such reports furnished to Middlefield and written representations to Middlefield, all section 16(a) filing requirements applicable to Middlefield’s executive officers and directors were complied with during the fiscal year ended December 31, 2023, except for: (i) one Form 4 that was not timely filed for each of the following current and former executive officers relating to a stock award, Michael L. Allen, Courtney M. Erminio, James R. Heslop, II, Michael C. Ranttila, Alfred F. Thompson Jr., and Ronald L. Zimmerly, Jr., (ii) one late amendment to Form 3 and one late amendment to Form 4 that were not timely filed for Thomas M. Wilson and (iii) one Form 3 and two Form 4s that failed to report shares of Company stock acquired by director Jennifer L. Moeller before she became a director of Middlefield.

(3)       The 2023 cash incentive payments under The Middlefield Banking Company’s Annual Incentive Plan were made in March, 2024, based on financial performance and the executives’ performance in 2023, and the 2022 cash incentive payments were made March 10, 2023, based on financial performance and the executives’ performance in 2022. Messrs. Ranttila and Zimmerly’s 2023 awards under the Annual Incentive Plan were based upon The Middlefield Banking Company achieving 87% of the targeted performance objective for net income, 76% of the targeted efficiency ratio, and 46% of the targeted ROA performance goal, but failing to achieve targeted performance for the classified asset ratio.

(4)       The figures in the All Other Compensation column are the sum of matching contributions under The Middlefield Banking Company’s 401(k) plan, contributions and interest earnings credited by The Middlefield Banking Company for each executive under the executive deferred compensation agreements, nonqualified deferred compensation expense recognized in 2023 to account for Mr. Zimmerly’s supplemental executive retirement plans, the imputed monetary value of life insurance policies related to Mr. Zimmerly’s split dollar agreement, and directors’ fees paid to Messrs. Heslop and Zimmerly. In 2023, the bank made contributions of $13,187 to the 401(k) plan account of Mr. Heslop, $13,187 to the 401(k) plan account of Mr. Zimmerly and $12,148 to the 401(k) plan account of Mr. Ranttila. The 2023 contributions and interest earnings for the executive deferred compensation agreements were interest earnings of $23,078 for Mr. Heslop, contributions of $23,800 for Mr. Zimmerly, and contributions of $18,200 and interest earnings of $1,302 for Mr. Ranttila. The nonqualified deferred compensation expense in 2023 to account for Mr. Zimmerly’s supplemental executive retirement plans was $33,165. Mr. Ranttila received a $65,000 payment in July, 2023 under the January 1, 2022 Executive Retention Agreement with The Middlefield Banking Company. The Executive Retention Agreement promised Mr. Ranttila three months’ annual base salary if he agreed to continue serving as an executive officer though July 1, 2023. The imputed value of life insurance policies for income tax purposes in 2023 was $249 for Mr. Zimmerly. Mr. Heslop’s director compensation was $46,950 in 2023 and $50,648 in 2022. Mr. Zimmerly’s director compensation was $47,700 in 2023 and $500 in 2022.

As of the January 10, 2024 effective date of the separation agreement, Mr. Heslop received accelerated vesting of 10,957 shares covered by Mr. Heslop’s 2021, 2022, and 2023 restricted stock awards.

12 

(6)       In connection with the closing of the merger with Liberty Bancshares, Inc., Middlefield’s board of directors approved payment of a discretionary incentive bonus of approximately $150,000 to Mr. Heslop. One half of the award was payable in cash and the balance was payable in immediately vested shares on an after-tax basis. The stock portion of the bonus payable in shares was based upon the closing price of Middlefield common stock on December 1, 2022. The discretionary incentive bonus rewarded Mr. Heslop for his efforts in completing the merger.

(7)       Messrs. Zimmerly and Ranttila received conditional stock awards on March 10, 2023. The number of shares awarded was 3,722 shares to Mr. Zimmerly and 2,846 shares to Mr. Ranttila. The award amount is a percentage of the award recipient’s salary, divided by the share price at the close of market on December 31, 2022. The closing price of the shares on December 31, 2022, was $27.40. The percentage of salary for purposes of calculating the awards to Messrs. Zimmerly and Ranttila is 30%. To become vested in and entitled to the stock award, each executive is required to maintain continuous service with Middlefield until the third anniversary of the award. The performance condition will be satisfied if the average annual shareholder return on Middlefield stock for the years 2023, 2024, and 2025 is at least 10.00%. For this purpose, annual return is the sum of annual dividends and the excess of the closing stock price on the final trading day of the year over the closing price on the final trading day of the preceding year, divided by the closing stock price on the final trading day of the preceding year. The three-year average of the annual returns for 2023, 2024, and 2025 will determine whether the 10.00% goal is satisfied. If the 10.00% goal is not satisfied but the average annual return is positive, the recipient will become the owner of and entitled to a portion of the conditional stock award, forfeiting the remainder. The portion that will be issued to the recipient is the percentage of the total award equal to the percentage achievement of the 10.00% goal. If the average annual return is negative, the entire award is forfeited, unless the Compensation Committee waives the performance condition. If average annual return exceeds 10.00%, the nominal amount of the conditional stock award will increase, up to a maximum of 125% of the nominal award, increasing based on the percentage excess of actual average return over the 10.00% goal. Accordingly, the maximum potential conditional stock award total is 4,652 shares for Mr. Zimmerly and 3,557 shares for Mr. Ranttila. The terms of the conditional stock award for Mr. Zimmerly are set forth in the Form 8-K Current Report filed by Middlefield with the SEC on March 17, 2023.

(8)       In connection with Middlefield’s merger with Liberty Bancshares, Inc., Mr. Zimmerly received a restricted stock award with a value of $325,000. The closing price of Middlefield stock on December 1, 2022 was $28.60 per share, resulting in a grant of 11,364 shares to Mr. Zimmerly. Mr. Zimmerly’s restricted stock grant vests equally over a three-year period, provided that Mr. Zimmerly remains continuously employed by Middlefield. Vesting of the restricted stock grant accelerates in the event of good reason resignation or involuntary termination without cause.

(9)       Mr. Ranttila was appointed as the Company’s Chief Financial Officer, Treasurer and Executive Vice President effective May 1, 2023. Mr. Ranttila was not a named executive officer in 2022.

Perquisites and other personal benefits provided to each of the named executive officers in 2023 and 2022 had a value of less than $10,000.

Annual Incentive Plan. In 2003, The Middlefield Banking Company established the Annual Incentive Plan, a short-term cash incentive plan that rewards employees with additional cash compensation if specific objectives are achieved. An employee’s potential cash incentive payment under the Annual Incentive Plan depends upon two factors: (x) the employee’s position, which establishes a maximum cash incentive award as a percent of base salary, and (y) the degree to which the performance targets, such as targeted income, and individual performance targets, are achieved. Annual incentive payments under the plan for a particular year generally are based on objective financial performance criteria established by The Middlefield Banking Company board, with the Compensation Committee’s recommendation.

The bank-wide performance objectives that had to be achieved in 2023 in order for Messrs. Zimmerly and Ranttila to receive a cash incentive payment under the Annual Incentive Plan included a pre-tax, pre-provision earnings goal, a goal for the bank’s return on average assets (ROAA), an efficiency ratio goal, a goal for non-accrual loans and accruing loans 90 or more days past due, and a goal having to do with the regulatory and supervisory status of Middlefield and The Middlefield Banking Company. In future years, other financial performance measures could be taken into account, such as return on average equity (ROAE), deposit growth, and net interest margin. The bank’s Compensation Committee also considers individual performance goals.

The Annual Incentive Plan was amended and restated effective March 12, 2019. A copy of the plan is included as exhibit 10.22 to the Form 8-K Current Report that we filed with the SEC on March 12, 2019, which is available for viewing or download at www.sec.gov. All employees are eligible for awards under the Annual Incentive Plan. Employees who are not members of the senior management team received cash incentive payments for 2023 operating results consistent with the plan. The President and Chief Executive Officer is eligible for a cash bonus in an amount ranging from a minimum of 12% of his salary if actual performance is 90% of targeted performance goals established by the bank’s Compensation Committee, 24% of salary if actual performance is 100% of targeted performance goals, and a maximum of 36% of salary if actual performance is 110% or more of targeted performance goals. The annual awards under the plan for the President and Chief Executive Officer and the Chief Financial Officer are exclusively determined by the bank’s performance. Under the Annual Incentive Plan, Mr. Ranttila as Chief Financial Officer is eligible for cash bonuses in an amount ranging from a minimum of 12% of salary if actual performance is 90% of targeted performance goals, 18% of salary if actual performance is 100% of targeted performance goals, and a maximum of 24% of salary if actual performance is 110% or more of targeted performance goals.

The Annual Incentive Plan has certain forfeiture and recoupment, or “clawback,” provisions that allow the board to rescind awards under the plan that have not yet been paid, and recover awards that have been paid, upon the occurrence of certain events. The Compensation Committee may rescind and not pay an incentive award to a participant in the Annual

13 

Incentive Plan if the Compensation Committee finds that the participant failed significantly to satisfy expectations, engaged in fraudulent or unethical conduct in the course of the participant’s employment or committed an intentional violation of bank policy. The Annual Incentive Plan also provides that a participant in the plan agrees to repay to The Middlefield Banking Company any award that is entirely or partially attributable to a financial reporting error. If an award is entirely attributable to a financial reporting error, the participant must promptly repay to The Middlefield Banking Company the entire amount of the award and if an award is partially attributable to a financial reporting error the participant must promptly repay to The Middlefield Banking Company the portion of the award that the Compensation Committee determines is attributable to the financial reporting error.

2017 Omnibus Equity Plan. The 2017 Omnibus Equity Plan approved by shareholders on May 10, 2017 authorizes the issuance of 448,000 shares of Middlefield common stock. Middlefield’s Compensation Committee administers the Omnibus Equity Plan. Shares of common stock issued under the Omnibus Equity Plan may be treasury shares, authorized and unissued shares not reserved for any other purpose, or a combination of treasury shares and authorized but unissued shares. Awards to employees may take the form of incentive stock options, or ISOs, that qualify for favored tax treatment under Internal Revenue Code section 422, stock options that do not qualify under section 422, referred to as NQSOs, stock appreciation rights, or SARs, restricted stock, restricted stock units, performance shares, which become fully vested if conditions imposed in the award agreement are satisfied, and other stock-based awards. In contrast to the kinds of awards that may be made to employees, non-employee directors are eligible for awards of NQSOs, restricted stock, restricted stock units and other stock-based awards. The terms of each award are stated in award agreements. Of the shares authorized for issuance under the Omnibus Equity Plan, up to one half, or 224,000 shares, may be reserved for issuance under incentive stock options. The aggregate number of shares underlying awards granted to an individual participant in a single year may not exceed 44,800.

Unless the participant’s award agreement provides otherwise, when a participant employee’s employment terminates or when a non-employee director participant’s service terminates, the portion of any award held by the participant that is not exercisable is forfeited and the portion of any restricted stock award or performance share award that is unvested and held in escrow is forfeited. All NQSOs, SARs, ISOs and other stock-based awards held by the participant that are exercisable are forfeited if not exercised before the earlier of the expiration date specified in the award agreement or 90 days after termination occurs. A participant’s outstanding awards are forfeited if the participant’s employment or director service terminates for cause or if in Middlefield’s judgment a basis for termination for cause exists, regardless of whether the awards are exercisable and regardless of whether the participant’s employment or director service actually terminates. However, shares of restricted stock or performance shares that have been released from escrow and distributed to the participant are not affected by a termination for cause.

If a change in control of Middlefield occurs, the Compensation Committee has broad authority and sole discretion to take actions it deems appropriate to preserve the value of participants’ awards. In general, a change in control means one or more of the following events occur –

● a change in the composition of Middlefield’s board of directors, after which the incumbent members of the board on the effective date of the 2017 Omnibus Equity Plan – including their successors whose election or nomination was approved by a vote of at least two-thirds of those incumbent directors and their successors - no longer represent a majority of the board,

● a person (other than persons such as subsidiaries or benefit plans) becomes a beneficial owner of Middlefield securities representing 25% or more of the combined voting power of all securities eligible to vote for the election of directors, excepting business combinations after which Middlefield’s shareholders own more than 50% of the resulting company and except for stock issuances approved by incumbent directors and their successors;

● a merger, consolidation, share exchange, or similar form of business combination transaction requiring approval of Middlefield’s shareholders, excepting business combinations after which Middlefield’s shareholders own more than 50% of the resulting company; or

● Middlefield’s shareholders approve a plan of complete liquidation or dissolution or sale of all or substantially all of Middlefield’s assets.

To align equity compensation practices with shareholder interests, in 2015 we implemented a change in our equity compensation practices, awarding restricted stock with vesting that is typically dependent not only on continued service over time but also on achieving an established average annual return on Middlefield stock. We discontinued granting stock options to executives in 2011, and therefore the Compensation Committee does not have a formal written policy regarding the timing of stock option grants.

Executive officers who receive restricted stock awards under the 2017 Omnibus Equity Plan agree to certain restrictive covenants that will apply during the 12-month period immediately after the executive officer’s termination of employment with Middlefield or any related entity, regardless of the reason for termination or separation. During the 12-month post-employment period, the executive officer recipient of a stock award agrees not to engage in the following activities in selected Ohio geographies within 25 miles of any banking office of Middlefield or any related entity: (i) solicit any customer of Middlefield or a related entity to accept or purchase banking products or services (as defined in the stock award agreement), (ii) influence or attempt to influence any customer, or other business partner of Middlefield or a related entity to alter that person’s business relationship with Middlefield or the related entity, and (iii) provide banking products or services to any customer on behalf of anyone other than Middlefield or a related entity.

An executive officer recipient of a stock award also agrees during the 12-month post-employment period to refrain from soliciting, encouraging or inducing in any way any employee, any business partner of Middlefield or a related entity to terminate an employment or contractual relationship with Middlefield or the related entity; or from hiring any person employed by Middlefield or a related entity during the two-year period before the executive officer’s employment termination with Middlefield or a related entity.

Executive Deferred Compensation Agreements. The Middlefield Banking Company entered into executive variable benefit deferred compensation agreements with Mr. Zimmerly on December 5, 2022, and with Mr. Ranttila on December 15, 2020. Mr. Zimmerly’s executive variable benefit deferred compensation agreement became effective January 1, 2023. Under the executive variable benefit deferred compensation agreements, the executives will receive an annual contribution ranging from 5% to 15% of their base salary. Contributions exceeding 5% of salary are conditional on achievement of performance goals involving (i) The Middlefield Banking Company’s net income for the plan year and (ii) The Middlefield Banking Company’s peer ranking for the plan year based on the top 50% of all FDIC-insured commercial banks having assets between $1 billion and $3 billion as reported on the Uniform Bank Performance Report (“UBPR”) available from the Federal Financial Institutions Examination Council’s website at www.ffiec.gov/UBPR.htm. The UBPR is an analytical tool created for bank supervisory, examination, and management purposes. In a concise format, the UBPR shows the impact of management decisions and economic conditions on a bank’s performance and balance-sheet composition. Each of the two performance goals can account for a contribution of up to 7.5% of the executive’s base annual salary. The net income goal for each year is established by The Middlefield Banking Company’s Compensation Committee by March 31 of that year. The Compensation Committee’s decisions are not final unless approved by a majority of the independent directors of The Middlefield Banking Company.

Under the executive deferred compensation agreements, except in the case of the executive’s death or a change in control of Middlefield, Messrs. Zimmerly and Ranttila are entitled to receive the account balance as of the end of the month in which the executive has a separation from service. The account balance will be paid in 180 substantially equal monthly installments commencing on the first day of the month after the executive attains age 65.

Supplemental Executive Retirement Plans. The Middlefield Banking Company maintains three supplemental executive retirement plans (“SERPs”) for the benefit of Mr. Zimmerly that The Middlefield Banking Company assumed in the merger with Liberty National Bank completed on December 1, 2022. The first SERP was effective as of January 1, 2012, and amended on July 14, 2015, at which time the benefits were frozen. A secondary SERP was effective as of October 1, 2015. The third SERP, a Lifetime Income Non-Qualified Solution (“LINQS+”) SERP, was effective as of October 1, 2015.

Under the terms of the frozen 2012 SERP, as amended, Mr. Zimmerly is entitled to receive a monthly payment of $1,154.42 for a period of 180 months commencing on the later of (a) the first business day of the month following the month in which Mr. Zimmerly attains age 65 or (b) the first business day of the first calendar month following the end of the calendar month in which Mr. Zimmerly experiences a separation from service (as defined in the SERP agreement) from The Middlefield Banking Company and all affiliated companies.

The 2015 secondary SERP provides supplemental retirement benefits financed by an annuity that has been designed to provide a future source of funds for the retirement benefits provided by the SERP agreement. Under the terms of

15 

the secondary SERP, upon Mr. Zimmerly’s separation from service with The Middlefield Banking Company for any reason other than death or termination for cause, Mr. Zimmerly will be entitled to a monthly benefit equal to: (a) the amount that is paid from the annuity that finances the retirement benefit, with such amount determined as of the date of separation from service, less (b) any amounts due and paid under the 2012 frozen SERP, as amended. The retirement benefit will be payable in equal monthly installments for the life of Mr. Zimmerly commencing on the later of the first day of the month following Mr. Zimmerly attaining the normal retirement age or the first day of the month following Mr. Zimmerly’s separation from service. Normal retirement age under the secondary SERP is age 65.

The nonqualified deferred compensation benefit provided by the LINQS+ SERP is financed by six annuities that have been designed to provide a future source of funds for the retirement benefit provided by the LINQS+ SERP. Mr. Zimmerly is fully vested in the six annuities. Under the terms of the LINQS+ SERP, upon Mr. Zimmerly’s separation from service, The Middlefield Banking Company will make the retirement benefit payments by transferring ownership of the annuity contracts to Mr. Zimmerly on or before the first day of the second month after Mr. Zimmerly attains age 60 in June 2024. At December 31, 2023, the aggregate value of the vested annuities that finance the LINQS+ SERP is $697,395.45.

Split Dollar Life Insurance Agreement. The Middlefield Banking Company maintains a split dollar life insurance agreement for the benefit of Mr. Zimmerly as a result of the merger with Liberty National Bank completed on December 1, 2022. The split dollar life insurance agreement promises a $100,000 pre-retirement split dollar life insurance benefit to Mr. Zimmerly’s heirs if Mr. Zimmerly dies before retirement.

Executive Survivor Income Arrangement. The Middlefield Banking Company has an executive survivor income arrangement with Mr. Ranttila. The executive’s designated beneficiary would receive $100,000 at the executive’s death if the executive dies in active service to The Middlefield Banking Company.

Change-in-Control and Severance Agreements. Although Middlefield and its subsidiaries do not have written employment agreements with officers, Middlefield entered into severance or change-in-control agreements with some of its executive officers, including Messrs. Zimmerly and Ranttila. For purposes of the severance and change-in-control agreements, the term “change in control” is defined as it is defined in Internal Revenue Code section 409A and implementing rules. The lump-sum severance benefit is payable immediately after involuntary termination without cause or voluntary termination with good reason occurring within 24 months after a change in control.

The agreements promise to each executive a lump-sum payment calculated as a multiple of the executive’s salary and the executive’s cash bonus and cash incentive compensation. The multiple of compensation payable under the agreements is 2.5 times for Messrs. Zimmerly and Ranttila and ranges from one to two times for other executives. The agreements also promise continued life, health, and disability insurance coverage for one to two years after employment termination and legal fee reimbursement if the change-in-control agreements are challenged after a change in control.

Retirement Plan. Middlefield does not maintain a defined benefit or actuarial plan providing retirement benefits for officers or employees based on actual or average final compensation. The Middlefield Banking Company maintains a section 401(k) employee savings and investment plan for substantially all employees and officers who have more than one year of service. The bank’s contribution to the plan is based on 50% matching of voluntary contributions, up to 6% of compensation. An eligible employee may contribute up to 15% of his or her salary. Employee contributions are vested at all times. Bank contributions are fully vested after six years, vesting in 20% annual increments beginning with the second year. Employees also have life insurance benefits under a group term life insurance program, paying benefits to an employee’s beneficiary if the employee dies while employed by The Middlefield Banking Company, up to the lesser of (x) twice the employee’s annual salary at the time of death or (y) $200,000.

Transactions with Related Parties. Middlefield directors and executive officers and their associates are customers of and enter into banking transactions with The Middlefield Banking Company in the ordinary course of business on substantially the same terms – including interest rates and collateral – as those prevailing at the time for comparable transactions with persons not affiliated with Middlefield. Middlefield expects that these relationships and transactions will continue. During the year ended December 31, 2023, The Middlefield Banking Company had a commercial real estate loan in excess of $120,000 to an entity in which a Middlefield Banc Corp. director has a material ownership interest. The loan was made in the ordinary course of business on substantially the same terms, including interest rates and collateral, that prevailed at the time for comparable transactions with other persons not related to the bank and did not involve more than the normal risk of collectability or present other unfavorable features.

OUTSTANDING EQUITY AWARDS

The following table shows as of December 31, 2023, unvested and unearned stock awards. We have not granted stock options to executives since 2011.

Ronald L. Zimmerly, Jr.									3,722(2) 7,576(3)		120,481   245,235
Michael C. Ranttila									2,846(2) 2,016(4) 1,765(5)		92,125   65,257   57,133

(1) Pursuant to a separation agreement dated January 2, 2024, Mr. Heslop received accelerated vesting of Mr. Heslop’s 2021, 2022, and 2023 restricted stock awards with a market value of $322,793 as of the January 10, 2024 effective date of the separation agreement.

(2) Messrs. Zimmerly and Ranttila received conditional stock awards on March 10, 2023. The number of shares awarded was 3,722 shares to Mr. Zimmerly and 2,846 shares to Mr. Ranttila. The award amount is a percentage of the award recipient’s salary, divided by the share price at the close of market on December 31, 2022. The closing price of the shares on December 31, 2022, was $27.40. The percentage of salary for purposes of calculating the awards to Mr. Ranttila and Mr. Zimmerly is 30%. To become vested in and entitled to the stock award, each executive is required to maintain continuous service with Middlefield until the third anniversary of the award. The performance condition will be satisfied if the average annual shareholder return on Middlefield stock for the years 2023, 2024, and 2025 is at least 10.00%. For this purpose, annual return is the sum of annual dividends and the excess of the closing stock price on the final trading day of the year over the closing price on the final trading day of the preceding year, divided by the closing stock price on the final trading day of the preceding year. The three-year average of the annual returns for 2023, 2024, and 2025 will determine whether the 10.00% goal is satisfied. If the 10.00% goal is not satisfied but the average annual return is positive, the recipient will become the owner of and entitled to a portion of the conditional stock award, forfeiting the remainder. The portion that will be issued to the recipient is the percentage of the total award equal to the percentage achievement of the 10.00% goal. If the average annual return is negative, the entire award is forfeited, unless the Compensation Committee waives the performance condition. If average annual return exceeds 10.00%, the nominal amount of the conditional stock award will increase, up to a maximum of 125% of the nominal award, increasing based on the percentage excess of actual average return over the 10.00% goal. Accordingly, the maximum potential conditional stock award total is 4,652 shares for Mr. Zimmerly and 3,557 shares for Mr. Ranttila.

(3) Mr. Zimmerly received a restricted stock award of 11,364 shares on December 1, 2022. Mr. Zimmerly’s restricted stock grant vests annually in equal increments over a three-year period, provided Mr. Zimmerly remains continuously employed by Middlefield. Vesting of the restricted stock grant accelerates in the event of good reason resignation or involuntary termination without cause.

(4) Mr. Ranttila received a conditional stock award of 2,016 shares on February 23, 2022. The award amount is a percentage of Mr. Ranttila’s salary, divided by the share price at the close of market on December 31, 2021. The closing price of the shares on December 31, 2021, was $24.80. The percentage of salary for purposes of calculating the award to Mr. Ranttila is 25%. To become vested in and entitled to the stock award, Mr. Ranttila is required to maintain continuous service with Middlefield until the third anniversary of the award. The performance condition will be satisfied if the average annual return on Middlefield stock for the years 2022, 2023, and 2024 is at least 10.00%. For this purpose, annual return is the sum of annual dividends and the excess of the closing stock price on the final trading day of the year over the closing price on the final trading day of the preceding year, divided by the closing stock price on the final trading day of the preceding year. The three-year average of the annual returns for 2022, 2023, and 2024 will determine whether the 10.00% goal is satisfied. If the 10.00% goal is not satisfied but the average annual return is positive, Mr. Ranttila will become the owner of and entitled to a portion of the conditional stock award, forfeiting the remainder. The portion that will be issued to Mr. Ranttila is the percentage of the total award equal to the percentage achievement of the 10.00% goal. If the average annual return is negative, the entire award is forfeited, unless the Compensation Committee waives the performance condition. If average annual return exceeds 10.00%, the nominal amount of the conditional stock award will increase, up to a maximum of 125% of the nominal award, increasing based on the percentage excess of actual average return over the 10.00% goal. Accordingly, the maximum potential conditional stock award total for Mr. Ranttila is 2,520 shares.

17 

(5) Mr. Ranttila received a conditional stock award of 1,765 shares on February 23, 2021. The award amount is a percentage of the Mr. Ranttila’s salary, divided by the share price at the close of market on December 31, 2020. The closing price of the shares on December 31, 2020, was $22.50. The percentage of salary for purposes of calculating the award to Mr. Ranttila was 25%. To become vested in and entitled to the stock award, Mr. Ranttila was required to maintain continuous service with Middlefield until the third anniversary of the award. The performance condition would be satisfied if the average annual return on Middlefield stock for the years 2021, 2022, and 2023 was at least 10.00%. For this purpose, annual return was the sum of annual dividends and the excess of the closing stock price on the final trading day of the year over the closing price on the final trading day of the preceding year, divided by the closing stock price on the final trading day of the preceding year. The three-year average of the annual returns for 2021, 2022, and 2023 determined whether the 10.00% goal was satisfied. If average annual return exceeded 10.00%, the nominal amount of the conditional stock award would increase up to a maximum of 125% of the nominal award, increasing based on the percentage excess of actual average return over the 10.00% goal. Accordingly, the maximum potential conditional stock award total for Mr. Ranttila was 2,206 shares. The closing price on December 31, 2021, was $24.80, and dividends per share for 2021 were $0.69. The closing stock price on December 31, 2022, was $27.40, and dividends per share for 2022 were $0.81. The closing stock price on December 31, 2023, was $32.37, and dividends per share for 2023 were $0.85. Based on this, the three-year average annual return for 2021, 2022 and 2023 was 16.09%, which is 160.90% of the 10.00% goal, and Mr. Ranttila became fully vested in his maximum potential conditional stock award of 2,206 shares as of February 23, 2024.

Relationship Between Pay and Performance.

As described in more detail in pages 12 to 18 regarding Middlefield’s executive compensation program, Middlefield’s executive compensation program includes variable components in the form of annual incentive cash compensation and deferred compensation based upon Middlefield’s profitability, and performance-based equity awards that require Middlefield to achieve certain total shareholder return goals. Compensation decisions at Middlefield are made independently of SEC disclosure requirements. While Middlefield utilizes several performance measures to align executive compensation with Middlefield’s performance, all of those measures are not presented in the “Pay Versus Performance Table.” Moreover, Middlefield generally seeks to incentivize long-term performance and, therefore, does not specifically align Middlefield’s performance measures with compensation that is actually paid (as computed in accordance with Item 402(v) of SEC Regulation S-K) for a particular year.

Compensation Actually Paid versus Company Performance 

In accordance with the SEC’s disclosure requirements regarding pay versus performance, this section presents the SEC-defined “compensation actually paid” to Middlefield’s chief executive officers and Middlefield’s other named executive officers. As required by the SEC, this section compares compensation actually paid to total shareholder return and Middlefield’s net income for fiscal years 2023, 2022 and 2021.

The relationship between compensation actually paid and Middlefield’s financial performance over the three-year period shown in the preceding Pay Versus Performance Table is described as follows.

CEO

From 2022 to 2023, the SEC-defined “compensation actually paid” to Middlefield’s CEOs decreased by 11.94%, from $662,273 to $583,201. This decrease is a result of the transition in the Company’s CEO position and compensation arrangements made for Mr. Heslop in connection with his resignation on January 1, 2024. The Summary Compensation Table on page 12 is used to derive the figures in column (a) and column (c) of the Pay Versus Performance Table. The Summary Compensation Table does not include payments made by the Company to Mr. Heslop pursuant to a separation agreement dated January 2, 2024. Under the separation agreement, Mr. Heslop received $199,100 in lieu of an award under the Annual Incentive Plan and other welfare plans and $56,250 as the 2023 contribution for Mr. Heslop’s executive variable benefit deferred compensation agreement dated as of July 9, 2018.

Other NEOs

From 2022 to 2023, the SEC-defined “average compensation actually paid” to the other NEOs increased by $186,711 or 43.33%. This increase was caused primarily by the net increase in the year over year fair value of unvested restricted stock awards caused by the increase in the price of Middlefield’s stock from $27.40 per share at December 31, 2022 to $32.37 per share at December 31, 2023.

Total Shareholder Return and Net Income

The Company’s total shareholder return increased in 2023 by 20.3%. Net income increased by 10.8% from $15.7 million to $17.4 million, due largely to a $65.2 million, or 29.9%, increase in net interest income for the year ended December 31, 2023. The increase in net interest income was primarily attributed to the merger with Liberty Bancshares, Inc., and a $337.5 million increase in the average balance of loans receivable, coupled with a 90-basis point increase in the rate paid on those loans.

The relationship between compensation actually paid and Middlefield’s financial performance over the three-year period shown in the preceding Pay Versus Performance Table is illustrated in the following charts comparing PEO/NEO Compensation Actually Paid versus Total Shareholder Return (TSR) and Net Income.

PROPOSAL 1 — ELECTION OF FOUR DIRECTORS FOR THE TERM EXPIRING IN 2027

According to Article III, section 2, of Middlefield’s Regulations, the board may consist of no fewer than five and no more than 25 directors, the precise number being fixed or changed from time to time within that range by the board or by majority vote of shareholders acting at an annual meeting. The number of directors is currently fixed at twelve directors.

PROPOSAL 2 – ADVISORY VOTE ON EXECUTIVE COMPENSATION

We are subject to section 14A of the Exchange Act, which requires that we provide to our shareholders the opportunity to vote on the compensation of the executive officers named in the Summary Compensation Table. Commonly known as a say-on-pay vote, the shareholder vote required by section 14A is an advisory vote, which means that the vote is not binding on us, on our board of directors, or on the Compensation Committee. The say-on-pay vote is intended to be a vote on the executive officer compensation that is disclosed in this proxy statement in accordance with SEC disclosure rules.

The goals of our compensation arrangements are to provide fair and competitive compensation, to provide compensation that promotes the hiring and retention of the most talented personnel, to create incentives for and to reward superior performance, and to align the interests of our officers and employees with the interests of shareholders. The Compensation Committee and the board believe that Middlefield’s compensation arrangements are designed to achieve these goals and that the compensation arrangements reward performance promoting our long-term prosperity. Our compensation arrangements are continually evolving and are and will remain subject to ongoing review and evaluation by the board and by the Compensation Committee. Accordingly, we ask our shareholders to vote on the following resolution at the 2024 Annual Meeting:

“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed in Middlefield Banc Corp.’s Proxy Statement for the 2024 Annual Meeting in compliance with Item 402 of SEC Regulation S-K, including the compensation tables and narrative discussion, is hereby APPROVED.”

Approval of a majority of the votes cast will constitute approval of this proposal to approve the named executive officer compensation disclosed in this proxy statement. An abstention or broker non-vote is not counted as a vote cast, and as a result will have no effect on the vote to approve the proposal. A proxy that does not specify voting instructions will be voted in favor of this non-binding, advisory proposal. Although the results of the say-on-pay vote will not be binding on us, we expect to take the results into account in future compensation decisions.

The Board of Directors recommends that you vote “FOR” approval of the compensation of our named executive officers, as disclosed in this proxy statement.

PROPOSAL 3 – RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITOR

Middlefield’s independent auditor for the year ended December 31, 2023 was S.R. Snodgrass, P.C. The Audit Committee selected S.R. Snodgrass, P.C. to be Middlefield’s independent auditor for the fiscal year ending December 31, 2024. We expect one or more representatives of S.R. Snodgrass, P.C. to be present at the Annual Meeting. The representative of S.R. Snodgrass, P.C. will have the opportunity to make a statement if desired and will be available to respond to appropriate questions.

It is proposed that our shareholders ratify the appointment by the Audit Committee of S.R. Snodgrass, P.C. as Middlefield’s independent registered public accounting firm for the year ending December 31, 2024. Approval by the shareholders of the appointment of our independent registered public accounting firm is not required by law, any applicable stock exchange regulation or by our organizational documents, but the Audit Committee is submitting this matter to shareholders for ratification as a corporate governance practice. Ultimately, the Audit Committee retains full discretion and will make all determinations with respect to the appointment of the independent registered public accounting firm.

25 

For services in fiscal years ended December 31, 2023, and December 31, 2022, we paid S.R. Snodgrass, P.C. as follows –

	2023		2022
Audit Fees (1)	$	224,444	$	257,104
Audit-Related Fees (2)	$	10,200	$	10,000
Tax Fees (3)	$	17,556	$	18,050
All Other Fees (4)	$		$	6,275
	$	252,200	$	291,429

(1)     Audit fees pertain to professional services rendered in connection with the audit of Middlefield’s annual consolidated financial statements, reviews of the consolidated financial statements included in Middlefield’s Quarterly Reports on Form 10-Q and the Annual Report on Form 10-K. Audit fees for 2023 included fees related to Middlefield’s adoption of the current expected credit losses model on January 1, 2023. Audit fees for 2022 included fees associated with the issuance of consents in connection with the Registration Statement on Form S-4, as amended by a Registration Statement on Form S-4/A, filed by Middlefield to register the common shares issued in connection with the merger with Liberty Bancshares, Inc.

(2)     Audit-related fees consist of assistance with the audit of Middlefield’s 401(k) plan.

(3)     Tax service fees include fees for calculation of quarterly estimated taxes and for preparation of corporate income tax and franchise tax returns.

(4)     Other services include consulting related to merger integration.

The Audit Committee’s policy is to pre-approve all audit and permissible non-audit services provided by the independent auditors. These services may include audit services, audit-related services, tax services, and other services. Pre-approval is detailed as to the particular service or category of services and is generally subject to a budget. The independent auditors and management are required to periodically report to the Audit Committee regarding the extent of services provided by the independent auditors in accordance with this pre-approval, and the fees for the services performed to date. The Audit Committee may also pre-approve particular services on a case-by-case basis.

Auditor Independence. The Audit Committee believes that the non-audit services provided by S.R. Snodgrass, P.C. are compatible with maintaining the auditor’s independence. To the best of Middlefield’s knowledge, none of the time devoted by S.R. Snodgrass, P.C. on its engagement to audit Middlefield’s financial statements for the year ended December 31, 2023 is attributable to work performed by persons other than full-time, permanent employees of S.R. Snodgrass, P.C.

The Board of Directors recommends a vote “FOR” ratification of the appointment of S.R. Snodgrass, P.C. as Middlefield’s independent auditor for the fiscal year ending December 31, 2024.

This method of delivery, often referred to as “householding,” would permit Middlefield to send: (a) a single annual report and/or a single proxy statement or (b) a single notice of internet availability of proxy materials, as applicable, to any household at which two or more different registered shareholders reside if Middlefield reasonably believes such shareholders are members of the same family or otherwise share the same address or that one shareholder has multiple accounts. In each case, the registered shareholder(s) would be required to consent to the householding process in accordance with applicable SEC rules, and would be able at any time to request that Middlefield promptly deliver to such shareholder(s) a separate copy of the proxy materials subject to householding. The householding procedure is intended to reduce the volume of duplicate information shareholders receive and would reduce Middlefield’s expenses. Middlefield does not currently practice householding, but may institute householding in the future and will notify registered shareholders affected by householding at that time.

If you are the beneficial owner, but not the record holder, of Middlefield shares, your broker, bank or other nominee may only deliver one set of proxy materials and, as applicable, any other proxy materials that are delivered until such time as you or other shareholders sharing an address notify your nominee that you want to receive separate copies.

We will furnish a copy of our Form 10-K Annual Report for the year ended December 31, 2023 without charge to shareholders upon written request to: Mr. Michael C. Ranttila, Chief Financial Officer, Treasurer and Executive Vice President, Middlefield Banc Corp., 15985 East High Street, P.O. Box 35, Middlefield, Ohio 44062.
