#### Safe Harbor Regarding Forward-Looking Statements
*This report contains "forward-looking statements" within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995, including statements about the Company's financial condition, results of operations, asset quality trends and profitability. Forward-looking statements are not historical facts but instead represent only management's current expectations and forecasts regarding future events, many of which, by their nature, are inherently uncertain and outside of the Company's control. Forward-looking statements are preceded by terms such as "expects," "believes," "anticipates," "intends" and similar expressions, as well as any statements related to future expectations of performance or conditional verbs, such as "will," "would," "should," "could" or "may."* 

*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, the possibility that the closing of the proposed transaction is delayed or does not occur at all because required regulatory approvals, shareholder approval or other conditions to the transaction are not obtained or satisfied on a timely basis or at all; the possibility that the anticipated benefits of the transaction are not realized when expected or at all; the Company's failure to integrate Middlefield and Middlefield Bank in accordance with expectations; deviations from performance expectations related to Middlefield and Middlefield*

 *Bank; diversion of management's attention on the proposed transaction; significant changes in economic conditions in markets where the Company conducts business, which could materially impact credit quality trends; significant changes in U.S. economic conditions including those resulting from continued high rates of inflation, tightening monetary policy of the Board of Governors of the Federal Reserve, and effects of U.S. and foreign country tariff policies; general business conditions in the banking industry; the regulatory environment; general fluctuations in interest rates; demand for loans in the market areas where the Company conducts business; rapidly changing technology and evolving banking industry standards; competitive factors, including increased competition with regional and national financial institutions; and new service and product offerings by competitors and price pressures; and other factors disclosed periodically in the Company's filings with the SEC including the Company's Annual Report on Form 10-K for the year ended December 31, 2024 and subsequent Quarterly Reports on Form 10-Q and the Registration Statement on Form S-4 related to the proposed Merger. Such reports are available on the SEC's website at www.sec.gov and on the Company's website at https://www.farmersbankgroup.com under the "Investor Relations" section.* 

*Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, readers should not rely on any forward-looking statement as a prediction of future events. Any forward-looking statement speaks only as of the date on which it is made, and the Company expressly disclaims any obligation to update its forward-looking statements whether as a result of new information, future events or otherwise. All forward-looking statements, expressed or implied, included in or made in connection with this report are expressly qualified in their entirety by this cautionary statement.*
