FORWARD LOOKING STATEMENTS

This press release contains forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995 based upon Farmers' current expectations. 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 Farmers' control. Forward-looking statements are identified by terminology such as "believe," "may," "will," "estimate," "continue," "anticipate," "intend," "project," "plan," "expect," "goal," "seek," "future," "likely" or the negative or plural of these words 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. Numerous uncertainties, risks, and changes could cause or contribute to Farmers' 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 Company's failure to integrate Middlefield and Middlefield Bank with Farmers in accordance with expectations; deviations from performance expectations related to the combined company; general economic conditions, including changes in market interest rates and changes in monetary and fiscal policies of the federal government; legislative and regulatory changes; competitive conditions in the banking markets served by the Company's respective subsidiaries; the adequacy of the allowance for losses on loans and the level of future provisions for losses on loans; and other factors disclosed periodically in Farmers' filings with the Securities and Exchange Commission (the "SEC") including Farmers' Annual Report on Form 10-K for the year ended December 31, 2024, and subsequent Quarterly Reports on Form 10-Q. Such reports are available on the SEC's website at www.sec.gov and on the Company's website at 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.
