**ITEM 5.02(e): Material Compensatory Plan** 

At a meeting of the Compensation Committee of the Board of Directors of The Middlefield Banking Company held on January 12, 2026, the nonemployee directors approved bonuses to be payable on February 6, 2026 in the amount of $49,935.08 for President and Chief Executive Ronald L. Zimmerly, Jr., $22,827.52 for Chief Financial Officer, Executive Vice President and Treasurer Michael C. Ranttila, and $18,547.49 for Executive Vice President and Chief Banking Officer Michael L. Cheravitch.

At the same meeting, the Compensation Committee took action to establish award levels and plan performance goals under the Bank's Annual Incentive Plan for 2026 for Mr. Zimmerly, Chief Financial Officer Michael C. Ranttila, and Executive Vice President Michael L. Cheravitch.

The Annual Incentive Plan (the "Plan") is a short-term cash incentive plan that rewards Bank employees with additional cash compensation if specified objectives are achieved. For achievement of the 2026 plan performance goals, assuming receipt of shareholder and regulatory approvals for the pending merger with Farmers National Banc Corp., distributions under the Plan are expected to be made in cash to the executives and employees in the first quarter of 2026 on a pro rata basis due to the anticipated closing of the merger in March 2026. For 2026, the executives' performance measures under the Plan relate to maintaining service levels during the merger transition, completing all required integration tasks with Farmers National Banc Corp. and The Farmers National Bank of Canfield, and timely submission of regulatory disclosures.

The foregoing description of the Annual Incentive Plan does not purport to be complete and is qualified in its entirety by reference to the Annual Incentive Plan, which is filed as Exhibit 10.22 to the Form 8-K Current Report filed by Middlefield Banc Corp. (the "Company") on June 13, 2024, and is incorporated herein by reference.

**Forward-Looking Statements** 

This current report on Form 8-K contains "forward-looking statements" within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. These forward-looking statements are not statements of historical fact, but rather statements based on the Company's current expectations, beliefs and assumptions regarding the future of the Company's business, future plans and strategies, projections, anticipated events and trends, its intended results and future performance, the economy and other future conditions. Forward-looking statements are preceded by terms such as "will," "would," "should," "could," "may," "expect," "estimate," "believe," "anticipate," "intend," "plan" "project," or variations of these words, or similar expressions.

Forward-looking statements are not a guarantee of future performance and actual future results could differ materially from those contained in forward-looking information. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of the Company's control. Numerous uncertainties, risks, and changes could cause or contribute to the Company's actual results, performance, and achievements to be materially different from those expressed or implied by the forward-looking statements. Factors that may cause or contribute to these differences include, without limitation, risks that the proposed merger transaction will not close when expected or at all because required regulatory, shareholder or other approvals or conditions to closing are delayed or not received or satisfied on a timely basis or at all; risks that the benefits from the transaction may not be fully realized or may take longer to realize than expected, including as a result of changes in general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which the Company and Farmers

------

National Banc Corp. ("Farmers") operate; uncertainties regarding the ability of Farmers to promptly and effectively integrate the Company with its businesses in accordance with expectations; changes in business and operational strategies that may occur prior to the closing of the proposed merger with Farmers; uncertainties regarding the reaction to the transaction of the companies' respective customers, employees, and contractual counterparties; and risks relating to the diversion of management time on merger-related issues; and other factors disclosed periodically in the Company's filings with the SEC.

Because of the risks and uncertainties inherent in forward-looking statements, readers are cautioned not to place undue reliance on them, whether included in this report or made elsewhere from time to time by the Company or Farmers or on the Company or Farmers' behalf. The Company and Farmers disclaim any obligation and do not intend to update or revise any forward-looking statements contained in this communication, which speak only as of the date hereof, whether as a result of new information, future events or otherwise, except as required by federal securities laws.

Additional factors which could affect future results of the Company can be found in the Company's Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and the Current Reports on Form 8-K, in each case filed with the SEC and available on the SEC's website at https://www.sec.gov.
