Acquisition of Cortland Bancorp June 23, 2021 Exhibit 99.2

Disclosure Statement Forward-Looking Statements​ This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including statements about the financial condition, results of operations, asset quality trends and profitability of Farmers National Banc Corp. (“Farmers”). Forward-looking statements are not historical facts but instead express only management’s current expectations and forecasts of future events or long-term-goals, many of which, by their nature, are inherently uncertain and outside of Farmers’ 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.” Farmers’ actual results and financial condition may differ, possibly materially, from those indicated in these forward-looking statements. Factors that could cause Farmers’ actual results to differ materially from those described in the forward-looking statements include impacts from the COVID-19 pandemic on local, national and global economic conditions; higher default rates on loans made to our customers related to the COVID-19 pandemic and its impact on our customers’ operations and financial condition; unexpected changes in interest rates or disruptions in the mortgage markets related to COVID-19 or other responses to the health crisis; and the other factors contained in Farmers’ periodic reports and registration statements filed with the Securities and Exchange Commission, including its Annual Report on Form 10-K for the year ended December 31, 2020, and Quarterly Report on Form 10-Q, which have been filed with the Securities and Exchange Commission and are available on Farmers’ website (www.farmersbankgroup.com) and on the Securities and Exchange Commission’s website (www.sec.gov). Forward-looking statements are not guarantees of future performance and should not be relied upon as representing management’s views as of any subsequent date.  Farmers undertakes no obligation to update forward-looking statements, whether as a result of new information, future events or otherwise. ​ ​ Use of Non-GAAP Financial Measures ​ This presentation contains certain financial information determined by methods other than in accordance with accounting principles generally accepted in the United States (“GAAP”).  These non-GAAP financial measures include “Core Deposits” and “Tangible Common Equity ratio.”  Farmers believes that these non-GAAP financial measures provide both management and investors a more complete understanding of Farmers’ deposit profile and capital.   These non-GAAP financial measures are supplemental and are not a substitute for any analysis based on GAAP financial measures.  Because not all companies use the same calculation of “Core Deposits” and “Tangible Common Equity ratio,” this presentation may not be comparable to other similarly titled measures as calculated by other companies.   2
