QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING AND VOTING

When and Where will the Annual Meeting be Held?

The Annual Meeting will be held Thursday, April 19, 2018, at 3:30 p.m., Eastern Time, at the St. Michael Family Life Center, 300 North Broad Street, Canfield, Ohio 44406. To obtain directions to attend the Annual Meeting, please contact Shareholder Relations at (330) 533-5127.

Why did I Receive these Proxy Materials?

You have received these proxy materials because the Board of Directors is soliciting a proxy to vote your shares at the Annual Meeting. This proxy statement contains information that Farmers is required to provide to you under the rules of the Securities and Exchange Commission (the “Commission”) and is intended to assist you in voting your shares.

Who may Vote at the Annual Meeting?

The Board of Directors has set March 5, 2018 as the “record date” for the Annual Meeting. This means that only shareholders of record at the close of business on that date are entitled to notice of, and to vote at, the Annual Meeting or any adjournment(s) or postponement(s) thereof. At the close of business on March 5, 2018, 27,640,922 Common Shares were issued and outstanding. Each Common Share entitles the holder to one vote on each item to be voted upon at the Annual Meeting and there is no cumulative voting.

What is the Difference between Holding Shares as a “Shareholder of Record” and as a “Beneficial Owner”?

If your Farmers’ shares are registered directly in your name, you are considered the “shareholder of record” of those shares. Farmers has sent these proxy materials directly to all “shareholders of record.” Alternatively, if your Farmers’ shares are held in an account at a brokerage firm, bank, broker-dealer or other similar organization, which is sometimes called “street name,” then you are the “beneficial owner” of those shares, and these proxy materials were forwarded to you by that organization. The organization holding your shares is the shareholder of record for purposes of voting the shares at the Annual Meeting. As the beneficial owner, you have the right to direct that organization how to vote the Common Shares held in your account by following the voting instructions the organization provides to you.

How do I Vote?

Shareholders of record may vote on matters that are properly presented at the Annual Meeting in four ways:

For the Annual Meeting, Farmers is offering shareholders of record the opportunity to vote their Common Shares electronically through the Internet or by telephone by following

2

the procedures described on the enclosed proxy instead of submitting the enclosed proxy by mail. In order to vote via the Internet or by telephone, please have the enclosed proxy in hand, and go to the website listed on the proxy or call the number and follow the instructions. The Internet and telephone voting procedures are designed to authenticate shareholder identities, to allow shareholders to give their voting instructions, and to confirm that shareholder instructions have been recorded properly. Shareholders voting through the Internet should understand that they may bear certain costs associated with Internet access, such as usage charges from their Internet service providers. The deadline for voting through the Internet or by telephone is 3:30 a.m., Eastern Time, on April 19, 2018.

If you hold your Common Shares in street name, you should follow the voting instructions provided to you by the organization that holds your Common Shares. If you plan to attend the Annual Meeting and vote in person, ballots will be available. If your Common Shares are held in the name of your broker, bank or other shareholder of record, you must bring a legal proxy from the shareholder of record indicating that you were the beneficial owner of the shares on March 5, 2018 in order to vote in person.

How will My Shares be Voted?

If you vote by mail, through the Internet, by telephone or in person, your Common Shares will be voted as you direct. If you submit a valid proxy prior to the Annual Meeting, but do not complete the voting instructions, your Common Shares will be voted:

Can Other Matters be Decided at the Annual Meeting?

On the date that this proxy statement was printed, Farmers was not aware of any matters to be raised at the Annual Meeting other than those included in this proxy statement. If you submit a valid proxy and other matters are properly presented for consideration at the Annual Meeting, then the individuals appointed as proxies will have the discretion to vote on those matters for you.

3

May I Revoke or Change My Vote?

Yes, proxies may be revoked at any time before a vote is taken or the authority granted is otherwise exercised. Revocation may be accomplished by:

If your Common Shares are held in street name and you wish to revoke your proxy, you should follow the instructions provided to you by the record holder of your shares. If you wish to revoke your proxy in person at the Annual Meeting, you must bring a legal proxy from the shareholder of record indicating that you were the beneficial owner of the Common Shares on March 5, 2018. Attending the Annual Meeting will not, by itself, revoke your proxy.

Who Pays the Cost of Proxy Solicitation?

The accompanying proxy is solicited by and on behalf of the Board of Directors, whose notice of meeting is attached to this proxy statement, and the entire cost of such solicitation will be borne by Farmers. In addition to the use of the mail, proxies may be solicited by personal interview, telephone, facsimile and electronic mail by directors, officers and employees of Farmers. Arrangements will be made with brokerage houses and other custodians, nominees and fiduciaries for the forwarding of solicitation material to the beneficial owners of Common Shares held of record by such persons, and Farmers will reimburse them for reasonable out-of-pocket expenses incurred by them in connection therewith. Farmers has engaged Morrow Sodali LLC, 470 West Avenue Stamford, CT 06902, to aid in the solicitation of proxies in order to assure a sufficient return of votes on the proposals to be presented at the Annual Meeting. The costs of such services are estimated at $9,000, plus reasonable distribution and mailing costs.

How Many Common Shares Must be Represented at the Annual Meeting in Order to Constitute a Quorum?

The shareholders present in person or by proxy at the Annual Meeting representing not less than one-third of Farmers’ outstanding Common Shares shall constitute a quorum for the Annual Meeting. Consequently, at least 9,213,641 Common Shares must be represented at the Annual Meeting in person or by proxy in order to constitute a quorum. Abstentions and “broker non-votes” are counted as present and entitled to vote for purposes of determining a quorum. Street name holders generally cannot vote their Common Shares directly and must instead instruct the broker, bank or other shareholder of record how to vote their Common Shares using the voting instructions provided by it. If a street name holder does not provide timely instructions, the broker or other nominee may have the authority to vote on some proposals but not others. If a broker or other nominee votes on one proposal, but does not vote on another proposal because the nominee does not have discretionary voting power and has not received instructions from the beneficial owner, this results in a broker non-vote. Broker non-votes on a matter are counted as present for purposes of establishing a quorum for the meeting, but are not considered entitled to vote on that particular matter.

4

What are the Voting Requirements to Elect the Directors and to Approve the Other Proposals Discussed in this Proxy Statement?

The vote required to approve each of the proposals that are scheduled to be presented at the Annual Meeting is as follows:

5

Under Ohio law, the Articles, and Farmers’ Amended Code of Regulations (the “Regulations”), the nominees for election as directors who receive the greatest number of votes cast will be elected directors. Each shareholder will be entitled to cast one vote for each common share owned, and shareholders may not cumulate votes in the election of directors. Common shares as to which the authority to vote is withheld are not counted toward the election of directors. However, the Board of Directors has adopted a “Majority Vote Withheld Policy” in the event that “Withhold Authority” has been indicated by a majority of the votes cast with respect to any director in an uncontested election. A summary of this policy is set forth under the caption “CORPORATE GOVERNANCE — Policies of the Board of Directors” beginning on page 11 of this proxy statement.

6

CORPORATE GOVERNANCE

The Board of Directors — Independence

The Board of Directors is currently comprised of 11 members, four of whom are nominees for re-election at the Annual Meeting. Additional information regarding each director nominee is set forth in “Proposal One — Election of Directors” beginning on page 16 of this proxy statement. In 2017, the Board of Directors affirmatively determined that each of the directors listed below is an “independent director” under the rules of The NASDAQ Stock Market LLC (“NASDAQ”):

The only director (or director nominee) of Farmers who has been determined by the Board of Directors not to be independent is Kevin J. Helmick, the Company’s President and Chief Executive Officer.

During 2017, certain current directors and executive officers of Farmers, and their associates, were customers of, and had banking transactions with, various subsidiaries of the Company, including Farmers’ subsidiary bank, The Farmers National Bank of Canfield (“Farmers Bank”). All relationships between any director or executive officer and Farmers or any of its subsidiaries were conducted in the ordinary course of business. Farmers encourages its directors and executive officers to maintain these relationships and expects that these transactions will continue in the future. All loans and loan commitments included in such transactions were made and will be made: (i) in the ordinary course of business; (ii) on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to Farmers; and (iii) without more than the normal risk of collectability or present other unfavorable features. After reviewing the details of these relationships, the Board of Directors has determined that such relationships do not interfere with the exercise of any director’s independent judgment in carrying out his or her responsibilities.

In assessing the independence of directors, the Board of Directors also considers the business relationships between Farmers and its directors or their affiliated businesses other than ordinary banking relationships, if any. Where such business relationships other than ordinary banking relationships exist, the Board of Directors evaluates the scope and nature of each business relationship. There were no such business relationships between Farmers and its directors or the directors’ affiliated companies that were so considered by the Board of Directors in 2017.

Certain Relationships and Related Transactions

Farmers’ Audit Committee is responsible for reviewing and approving all related party transactions that are material to the Company’s consolidated financial statements or otherwise require disclosure under Item 404 of Regulation S-K. Extensions of credit by Farmers or any of its subsidiaries to “insiders” of the Company or its subsidiaries are also regulated by Regulation O adopted under the Federal Reserve Act and the Federal Deposit Insurance Corporation Improvement Act. It is Farmers’ policy that any transactions with

7

persons whom Regulation O defines as “insiders” (i.e., executive officers, directors, principal shareholders and their related interests) are engaged in the same manner as transactions conducted with all members of the public. Transactions are reviewed and approved by the Board of Directors either on a case-by-case basis (such as loans made by Farmers Bank to an insider) or, in the case of an ongoing relationship, at the outset of the relationship with periodic review. All loans to insiders of Farmers: (i) are made in the ordinary course of business; (ii) are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to the Company; and (iii) do not involve more than the normal risk of collectability or present other unfavorable features.

Attendance at Meetings

The Board of Directors held 13 meetings during 2017. All incumbent directors attended at least 75% of the total of all meetings of the Board of Directors and any committees thereof on which such director served during the year. In accordance with Farmers’ Corporate Governance Guidelines (the “Corporate Governance Guidelines”), directors are expected to attend all meetings of the Board of Directors, although it is understood that, on occasion, a director may not be able to attend a meeting. Directors are encouraged to attend the Annual Meeting. All of the current members of the Board of Directors other than Edward W. Muransky attended the 2017 Annual Meeting held on April 20, 2017.

Board Leadership Structure and Role in Risk Oversight

The Board of Directors has appointed Lance J. Ciroli as its non-executive Chairman. As Chairman, Mr. Ciroli presides over meetings of the Board of Directors, consults and advises the Board and its committees on the business and affairs of Farmers, and performs other responsibilities as may be assigned by the Board from time to time. The Board of Directors has also appointed James R. Smail as its non-executive Vice-Chair. As Vice-Chair, Mr. Smail presides over meetings of the Board of Directors in the absence of Mr. Ciroli, and also consults and advises the Board and its committees on the business and affairs of Farmers, and performs other responsibilities as may be assigned by the Board from time to time. Kevin J. Helmick, as President and Chief Executive Officer, is responsible both for overseeing Farmers’ day-to-day operations and for establishing and leading the execution of the Company’s long-term strategic objectives, subject to the overall direction and supervision of the Board of Directors and its committees. Farmers does not have a formal policy with respect to separation of the offices of Chairman of the Board and Chief Executive Officer, as the Board of Directors believes that flexibility in appointing the Chairman of the Board allows the Board of Directors to make a determination as to such position from time to time and in a manner that it believes is in the best interest of Farmers and its shareholders. The Board of Directors believes that the current structure best serves Farmers because it allows Mr. Helmick to focus on managing the Company’s day-to-day business while allowing Mr. Ciroli to lead the Board of Directors in its primary role of review and oversight of management. The Board of Directors also believes that its leadership structure has created an environment of open, efficient communication between the Board and management, enabling the Board to maintain an active, informed role in risk management by being able to monitor and manage those matters that may present significant risks to Farmers.

The role of the Board of Directors in Farmers’ risk management process includes reviewing regular reports from senior management on areas of material risk to the Company, including operational, financial, legal, regulatory and strategic risks. The Board of Directors reviews these reports to enable it to understand and assess Farmers’ risk assessment, risk

8

management and risk mitigation strategies. While the Board of Directors has the ultimate oversight responsibility for the risk management process, various committees of both management and the Board also have responsibility for risk management. In accordance with the Board Enterprise Risk Management Committee Charter, the Board Enterprise Risk Management Committee assists the Board of Directors in its oversight of management’s implementation and enforcement of Farmers’ policies, procedures and practices relating to: (i) the management of enterprise-wide risk; (ii) compliance with applicable laws and regulations and the maintenance of appropriate regulatory and economic capital and reserve levels; and (iii) the Company’s long-term strategic plans and initiatives. In addition, the Audit Committee assists the Board of Directors in overseeing and monitoring management’s conduct of Farmers’ financial reporting process and system of internal accounting and financial controls. Finally, the Compensation Committee oversees the management of risks relating to executive and non-executive compensation plans and arrangements. While each committee oversees certain risks and the management of such risks, the entire Board is regularly informed of such risks through committee reports.

Committees of the Board of Directors

The Board of Directors conducts its business through meetings of the Board and the following committees: (i) Audit Committee; (ii) Compensation Committee; (iii) Corporate Governance and Nominating Committee; (iv) Board Enterprise Risk Management Committee; and (v) Executive Committee. Each committee other than the Executive Committee meets on a regular basis and each committee reports their deliberations and actions to the full Board of Directors. Each of the committees has the authority to engage outside experts, advisors and counsel to the extent it considers appropriate to assist the committee in its work.

Audit Committee

The Audit Committee assists the Board of Directors in fulfilling its responsibility to oversee the accounting and financial reporting process of the Company. The Audit Committee also reviews, evaluates and approves all related party transactions. The Audit Committee members currently are Earl R. Scott (Chairman), Gregory C. Bestic, Ralph D. Macali and Gregg Strollo, each of whom also served on the Audit Committee during 2017. The Board of Directors has determined that Earl R. Scott qualifies as an “audit committee financial expert.” Specifically, the Board of Directors has determined that Earl R. Scott has all of the attributes listed in the definition of an “audit committee financial expert” set forth in the Instruction to Item 407(d)(5)(i) of Regulation S-K and in the NASDAQ listing requirements. Mr. Scott has acquired these attributes through education and experience as a certified public accountant. All of the Audit Committee members are considered independent for purposes of NASDAQ listing requirements. The Audit Committee operates under a written charter, which is reviewed annually by the Audit Committee and the Board of Directors to reflect current Commission and NASDAQ rules, requirements and best corporate practices. A copy of the current Audit Committee Charter is available on Farmers’ website at www.farmersbankgroup.com. The Audit Committee held four meetings during 2017.

Compensation Committee

The Compensation Committee establishes policies and levels of reasonable compensation for the executive officers of the Company and generally administers the Company’s incentive compensation programs. The members of the Compensation Committee members currently are David Z. Paull (Chair), Anne Frederick Crawford, Terry A. Moore, Earl R. Scott, and James R. Smail, each of whom also served on the Compensation

9

Committee during 2017. All members of the Compensation Committee are considered independent for purposes of NASDAQ listing requirements. The Compensation Committee operates under a written charter, which is reviewed annually by the Compensation Committee and the Board of Directors to reflect current Commission and NASDAQ rules, requirements and best corporate practices. A copy of the current Compensation Committee Charter is available on Farmers’ website at www.farmersbankgroup.com. The Compensation Committee held eight meetings during 2017.

Pursuant to the terms of its charter, the Compensation Committee may, in its discretion, delegate all or a portion of its duties and responsibilities to a subcommittee of the Compensation Committee. In addition, the Compensation Committee may invite such members of management to its meetings, as it may deem desirable or appropriate, consistent with the maintenance of the confidentiality of compensation discussions. In addition, the Compensation Committee may delegate to the Chief Executive Officer, or another executive designee, the authority to approve salary and other compensation for employees below the executive officer level in accordance with overall pools, policy guidelines and limits approved by the Committee. Pursuant to its charter, the Compensation Committee has the authority to select, retain, terminate and approve the fees and other retention terms of special counsel or other experts or consultants, as it deems appropriate, without seeking approval of the Board or management. Additional information regarding the Compensation Committee’s role is set forth in the “COMPENSATION DISCUSSION AND ANALYSIS” section of this proxy statement, beginning on page 28.

Corporate Governance and Nominating Committee

The Corporate Governance and Nominating Committee’s purpose is to: (i) identify and recommend individuals to the Board of Directors for nomination as members of the Board and its committees; (ii) promote effective corporate governance, including developing and recommending to the Board of Directors a set of corporate governance principles applicable to the Company; and (iii) lead the Board of Directors in its annual review of the Board’s performance and the performance of each of its committees. The members of the Corporate Governance and Nominating Committee currently are Gregory C. Bestic (Chair), Anne Frederick Crawford, Ralph D. Macali, Terry A. Moore, and Edward W. Muransky, each of whom also served on the Corporate Governance and Nominating Committee during 2017. All members of the Corporate Governance and Nominating Committee are independent for purposes of NASDAQ listing requirements. The Board of Directors has adopted a written charter for the Corporate Governance and Nominating Committee and the Corporate Governance Guidelines, both of which are reviewed annually by the Corporate Governance and Nominating Committee and the Board of Directors to reflect current Commission and NASDAQ rules, requirements and best corporate practices. Copies of the Corporate Governance and Nominating Committee Charter and the Corporate Governance Guidelines are available on Farmers’ website at www.farmersbankgroup.com. The Corporate Governance and Nominating Committee held six meetings during 2017.

Board Enterprise Risk Management Committee

The Board Enterprise Risk Management Committee oversees management’s implementation and enforcement of the Company’s policies, procedures and practices relating to the management of enterprise-wide risk. The members of the Board Enterprise Risk Management Committee currently are Lance J. Ciroli (Chair), Edward W. Muransky, David Z. Paull, James R. Smail and Gregg Strollo. During the 2017 calendar year, Mr. Scott also served on the Board Enterprise Risk Management Committee. The Board Enterprise Risk

10

Management Committee operates under a written charter, which is reviewed annually by the Committee and the Board of Directors. A copy of the current Board Enterprise Risk Management Committee Charter is available on Farmers’ website at www.farmersbankgroup.com. The Board Enterprise Risk Management Committee meets on a regular basis with Mr. Helmick and other executive officers of Farmers. The Board Enterprise Risk Management Committee held four meetings during 2017. Additional information regarding the Board Enterprise Risk Management Committee’s role is set forth in the “COMPENSATION DISCUSSION AND ANALYSIS” section of this proxy statement, beginning on page 28.

Executive Committee

The Executive Committee is authorized to act on behalf of the Board of Directors on all corporate actions for which applicable law does not require participation by the full Board. All actions taken by the Executive Committee must be reported at the next meeting of the Board of Directors. The members of the Executive Committee are James R. Smail (Chair), Lance J. Ciroli, Kevin J. Helmick, and Terry A. Moore, all of whom also served on the Executive Committee during 2017. The Executive Committee operates under a written charter, which is reviewed annually by the Committee and the Board of Directors. A copy of the current Executive Committee Charter is available on Farmers’ website at www.farmersbankgroup.com. The Executive Committee held eight meetings in 2017.

Policies of the Board of Directors

Majority Withheld Vote

The Board of Directors recognizes that, pursuant to Section 1701.55(B) of the Ohio Revised Code, director nominees who receive the greatest number of shareholder votes are automatically elected to the Board of Directors, regardless of whether the votes in favor of such nominees constitute a majority of the voting power of Farmers, because our Articles do not include alternative election standards. Nevertheless, the Board of Directors has adopted a policy that, in an uncontested election, any director nominee who receives a greater number of votes “withheld” from his or her election than votes “for” such election (a “Majority Withheld Vote”), should promptly tender his or her resignation to the Chairman of the Board of Directors. Thereafter, the Corporate Governance and Nominating Committee will consider the tendered resignation and recommend to the Board of Directors whether to accept or reject it. In considering whether to recommend to the Board of Directors to accept or reject the tendered resignation, the Corporate Governance and Nominating Committee will consider all information and factors deemed relevant, including, without limitation: (i) the reasons (if any) given by shareholders as to why they withheld their votes, and (ii) the qualifications and performance of the tendering director(s) and his or her contributions to the Board of Directors and Farmers. The Board of Directors will act on any tendered resignation within 90 days following certification of the shareholder vote. Following the Board of Directors’ determination, Farmers will promptly disclose the Board’s decision whether to accept or reject the director’s resignation offer (and, if applicable, the reasons for rejecting the resignation offer) in a press release and in a Current Report on Form 8-K. Any director who tenders his or her resignation pursuant to this provision shall not participate in the Corporate Governance and Nominating Committee’s consideration or action by the Board of Directors regarding whether to accept the resignation offer. If a majority of the Board of Directors receives a Majority Withheld Vote at the same election, then the independent directors who did not receive a Majority Withheld Vote will consider the resignation offers and whether to accept or reject them.

11

Director Nominations

The Corporate Governance and Nominating Committee will consider candidates for director, including those recommended by a shareholder who submits the person’s name and qualifications in writing. The Corporate Governance and Nominating Committee has no specific minimum qualifications for a recommended candidate, and does not consider shareholder recommended candidates differently from other candidates. The Corporate Governance and Nominating Committee considers the fit of an individual’s skills with those of other directors and potential directors in building a Board that is effective and responsive to the needs of the Company and its shareholders. The following attributes are considered important to such consideration, but all may not necessarily be possessed by any one director candidate:

While the Board of Directors does not have a formal diversity policy, diversity of viewpoints, background, experience and other demographics is one criterion on which the Corporate Governance and Nominating Committee bases its evaluation of potential candidates for director positions. When identifying first-time candidates or nominees for director, or in evaluating individuals recommended by shareholders, the Corporate Governance and Nominating Committee will consider diversity, the current composition of the Board in light of the diverse communities and geographies we serve, and the interplay of the candidate’s or nominee’s experience, education, skills, background, gender, race, ethnicity and other qualities and attributes with those of the other Board members. The inclusion of diversity in the listed criteria reflects the Board of Director’s belief that diversity is an important component of an effective Board and the Corporate Governance and Nominating Committee evaluates each potential director candidate on their specific skills, expertise and background, as well as traditional diversity concepts.

In addition to recommendations presented by shareholders, the Board of Directors maintains a current list of potential director candidates that fit the characteristics and qualifications of the Corporate Governance and Nominating Committee, which it uses from time to time to fill director vacancies or for director nominations. The Corporate Governance and Nominating Committee makes its recommendation regarding nominations to the Board of Directors, and nominees are selected by the Board of Directors.

Under the Regulations, a shareholder entitled to vote for the election of directors who intends to nominate a director for election must deliver written notice to the Secretary of Farmers no later than 90 days and no earlier than 120 days in advance of such meeting; provided, however, that if less than 90 days’ notice or prior disclosure of the date of the meeting is given or made to shareholders, written notice to the Secretary of the Company

12

must be delivered or mailed not later than the close of business on the seventh day following the date on which notice of such meeting is first given or made to shareholders. The Board of Directors has adopted a policy that annual meetings of shareholders will be held on the third Thursday of April of each year unless and until publicly announced otherwise, consistent with our general past practice and the Regulations. Accordingly, for purposes of our 2019 annual meeting of shareholders intended to be held on April 18, 2019, a nomination of a director for election must be received by Farmers’ Secretary no earlier than December 19, 2018 and not later than January 18, 2019.

The Corporate Governance Guidelines also formalize certain aspects of Farmers’ shareholder nomination process. Pursuant to the Regulations and/or the Corporate Governance Guidelines, each shareholder notice must include the following information regarding a director candidate:

In addition, the shareholder notice must also include the following information regarding the shareholder making the nomination:

13

In the case of any investment fund or similar organization that is a nominating shareholder, these shareholder disclosure obligations shall also apply to the principal advisor to the fund. Also, if the shareholder is other than an individual, these disclosure requirements apply to the shareholder’s principal shareholders, executive officers and other controlling parties.

During the course of any candidate’s consideration, the Corporate Governance and Nominating Committee may request additional information through written director questionnaires and further communications to assess whether the candidate satisfies, in the view of the committee, requirements of the Company’s Corporate Governance Guidelines, Director Code of Ethics, and other policies applicable to members of the Board and its committees.

If a nominating shareholder or director candidate believes that information supplied in response to any of the above inquiries is confidential, the shareholder or nominee may request confidential treatment for such information. In such event, the information shall be maintained on a confidential basis unless the Corporate Governance and Nominating Committee is advised by counsel that disclosure is appropriate in connection with the solicitation of proxies relating to the director candidate.

In the event that it is subsequently determined that any of the information provided by the candidate or nominating shareholder is materially inaccurate, a director candidate who provided the materially inaccurate information or whose nominating shareholder provided the materially inaccurate information shall be required to resign from the Board of Directors,

14

and, in the event of a refusal to resign, such a determination shall constitute grounds for removal from the Board, unless it is determined by the Corporate Governance and Nominating Committee that the inaccuracy was inadvertent.

Shareholder Proposals for 2019 Annual Meeting

Proposals by shareholders intended to be presented at the 2019 Annual Meeting of Shareholders must be received by the Secretary of Farmers no later than November 19, 2018, to be eligible for inclusion in Farmers’ proxy, notice of meeting, and proxy statement relating to its 2019 Annual Meeting. Farmers will not be required to include in its proxy, notice of meeting, or proxy statement, a shareholder proposal that is received after that date or that otherwise fails to meet the requirements for shareholder proposals established by the applicable Commission rules.

If a shareholder intends to submit a proposal at the 2019 Annual Meeting of Shareholders that is not eligible for inclusion in the proxy materials relating to the meeting, and the shareholder fails to give the Company notice in accordance with the requirements set forth in the Securities Exchange Act of 1934, as amended (the “Exchange Act”), by January 30, 2018, then the proxy holders will be allowed to use their discretionary authority with respect to such proposal if the proposal is properly raised at the Annual Meeting in 2019. The submission of such a notice does not ensure that a proposal can be raised at the 2019 Annual Meeting of Shareholders.

In each case written notice must be given to Farmers, addressed to its Corporate Secretary, at the following address: 20 South Broad Street, Canfield, Ohio 44406.

PROPOSAL TWO — ADOPTION AND APPROVAL OF AMENDMENT TO

ARTICLE IV OF THE ARTICLES OF INCORPORATION

General

On February 27, 2018, the Board of Directors adopted resolutions declaring it advisable and in the best interests of Farmers and its shareholders to amend Article IV of the Company’s Articles in order to increase the authorized number of our Common Shares from 35,000,000 to 50,000,000, and the Board is now unanimously proposing and recommending that our shareholders adopt and approve the proposed amendment to Article IV.

Description of the Shares Amendment

Article IV of the Company’s Articles currently authorizes 35,000,000 Common Shares. Of these authorized shares, as of March 5, 2018, 27,640,922 were issued and outstanding and 538,677 were held by the Company as treasury shares. Under our Articles, the Board of Directors is authorized without action of the shareholders to re-purchase shares of any class. An additional 500,000 Common Shares are reserved for issuance under the Farmers National Banc Corp. Share Ownership Plan (an employee stock purchase plan pursuant to which 92,470 shares have been issued), 500,000 Common Shares were reserved for issuance under our 2012 Equity Incentive Plan (pursuant to which awards representing 465,228 have been granted and remain outstanding), and 800,000 Common Shares are reserved for issuance under our 2017 Equity Incentive Plan (pursuant to which awards representing 124,618 shares have been granted and remain outstanding).

The Board of Directors is recommending that shareholders vote “FOR” the adoption of Proposal Two because the Board believes that the increase in the number of authorized Common Shares from 35,000,000 to 50,000,000 will provide us with the necessary ability to issue additional Common Shares in order to meet future business and financial needs and is, therefore, in the best interests of our shareholders. It is contemplated that the additional Common Shares could be used for appropriate corporate purposes as approved by the Board of Directors, including but not limited to the following:

At our 2013 Annual Meeting of Shareholders, shareholders approved a proposed amendment to our Articles which increased the number of our authorized Common Shares from 25,000,000 to the 35,000,000 currently authorized. Since that time, Farmers has successfully completed five acquisitions which have utilized a significant number of Common Shares, as one of the uses contemplated by such last proposed amendment to authorize additional Common Shares.

On July 1, 2013, we completed the acquisition of retirement planning consultancy National Associates, Inc. of Cleveland, Ohio, which included consideration comprised of cash and a total of over 225,000 Common Shares. On June 19, 2015, we completed the acquisition of all outstanding stock of National Bancshares Corporation, the parent company of First National Bank of Orrville. The transaction involved both cash and 7,262,955 Common Shares, totaling approximately $74.8 million. On October 1, 2015, Farmers completed the acquisition of Tri-State 1st Banc, Inc., the parent company of 1^st National Community Bank. Total consideration paid was $3.6 million in cash and 1,296,517 Common Shares,

24

worth approximately $10.7 million. On June 1, 2016, The Farmers National Bank of Canfield acquired Bowers Insurance Agency, Inc. and merged Bowers with the Bank’s wholly-owned insurance agency subsidiary. The transaction involved both cash and 123,280 Common Shares, totaling approximately $3.2 million, as well as potential future payments contingent upon satisfaction of performance targets. Finally, on August 15, 2017, Farmers acquired Monitor Bancorp, Inc., the holding company for Monitor Bank. The transaction involved both cash and 465,787 Common Shares, totaling approximately $7.5 million.

The following graph compares the cumulative five year total return to shareholders on our Common Shares relative to the cumulative total returns of the NASDAQ Composite index, the NASDAQ Bank index, and the SNL Micro Cap Bank index. The graph assumes that the value of an investment in Common Shares and in each of the indexes (including reinvestment of dividends) was $100 on December 31, 2012, and tracks that assumed investment through December 31, 2017. As indicated below, such an assumed investment in our Common Shares has outperformed each of the other indexes over the past five years.

The currently proposed increase in the authorized number of Common Shares would enable the Board of Directors to issue additional Common Shares as appropriate needs arise without further shareholder approval, except to the extent otherwise required by the Ohio General Corporation Law, state and federal securities laws, and the rules of any securities

25

exchange on which the Company’s Common Shares are then listed. There are no present plans to issue any of the additional Common Shares requested to be authorized by the proposed amendment to Article IV, and Farmers and the Board of Directors will not issue any of the additional Common Shares except under circumstances and on terms which it considers to be in the best interests of the Company.

The additional Common Shares requested to be authorized by the proposed amendment to Article IV will have rights identical to the currently issued and outstanding Common Shares of the Company, including being subject to the preemptive rights of existing shareholders to purchase any Common Shares issued for cash in the future under Farmers current Articles. Adoption of the proposed amendment and issuance of additional Common Shares will not affect the rights of the holders of our currently issued and outstanding Common Shares, except for effects incidental to increasing the number of Common Shares outstanding.

The proposed increase in the number of authorized Common Shares could be deemed to have an anti-takeover effect by discouraging an attempt by a third party to acquire control of the Company because the Company could issue the additional authorized Common Shares in an effort to dilute the common share ownership of the person seeking to obtain control or increase the voting power of persons who would support the Board of Directors in opposing the takeover attempt. However, the proposal to increase the authorized number of Common Shares is not in response to any current effort of which the Company is aware to obtain control of the Company.

The proposed amendment is not part of a plan by the Company to adopt other measures having potential anti-takeover effects. However, the Articles and Regulations of the Company currently include the following provisions which may be considered to have anti-takeover effects: (a) the classification of the Board of Directors into three classes, with one class of directors being elected each year; (b) the elimination of cumulative voting in the election of directors; (c) the requirement that shareholder nominations of candidates for election to the Board of Directors be made in writing and delivered or mailed to the secretary of the Company within specified timeframes; (d) the requirement that directors may be removed only by the affirmative vote of the holders of shares entitling them to exercise not less than two-thirds of the voting power of the Company at an election of directors; (e) the requirements that certain business combinations be approved by at least 80 percent of the voting power of the Company, depending on the nature of the recommendation of the Board of Directors with regard to the relevant acquisition; and (f) the lack of a provision opting out of application of the Ohio Merger Moratorium statute and its restrictions on persons who become the beneficial owner of ten percent or more of the shares of the Company.

Based on its determination that the increase in the number of authorized Common Shares from 35,000,000 to 50,000,000 will provide Farmers with the necessary ability to issue additional Common Shares in order to reasonably meet its future strategic, business and financial needs, and therefore is in the best interests of our shareholders, the Board of Directors unanimously recommends that shareholders vote “FOR” adoption of Proposal Two.

26

Proposed Amendment

If this Proposal Two is approved by shareholders, new Article IV would read in its entirety as follows:

ARTICLE IV:

The aggregate number of common shares which the corporation shall have the authority to issue is Fifty Million (50,000,000) shares, each without par value. The total number of authorized and outstanding common shares may be changed from time to time to reflect economic conditions of the corporation and business opportunities available to the shareholders of the corporation. The authorized and outstanding common shares may be redeemed by the corporation, whether at a regularly or specially called meeting for said purpose or otherwise. Furthermore, the corporation, through its Board of Directors, shall have the power to purchase, hold, sell and transfer the shares of its own capital stock, provided that it does not use its funds or property for the purchase of its own shares of capital stock when such use will cause any impairment of its capital, except where otherwise permitted by law, and provided further that shares of its own capital stock belonging to it are note voted upon directly or indirectly.

Vote Required and Board of Directors’ Recommendation

This proposal to amend Article IV requires the affirmative vote of the holders of Common Shares entitled to exercise at least two-thirds of the voting power of Farmers. Shareholders may vote “FOR,” “AGAINST” or “ABSTAIN” from voting on Proposal Two. Abstentions and broker non-votes will have the same effect as votes against Proposal Two.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE

SHAREHOLDERS VOTE “FOR” ADOPTION AND APPROVAL OF PROPOSAL TWO AND THE AMENDMENT TO ARTICLE IV TO INCREASE THE NUMBER OF AUTHORIZED COMMON SHARES.

COMPENSATION DISCUSSION AND ANALYSIS

Introduction

The following Compensation Discussion and Analysis provides information regarding the compensation programs for Farmers’ named executive officers, including: (i) the overall objectives of the Company’s compensation program and what it is designed to reward; (ii) each element of compensation that is provided; and (iii) an explanation of the Compensation Committee’s decisions regarding Farmers’ named executive officers. For purposes of this discussion, references to “we,” “our” and “us” refer to Farmers. This Compensation Discussion and Analysis is comprised of the following segments: Executive Summary, Compensation Philosophy and Objectives, 2017 Named Executive Officers Compensation, and Other Elements of our Compensation Programs. For 2017, our named executive officers were:

Executive Summary

We continued to deliver strong financial performance during 2017 which we believe compared well to our peers in the financial institution industry. We also believe that the compensation of our executive team reflected their continued successful efforts and aligned well with our financial performance.

Financial Performance and Significant Events affecting Executive Compensation in 2017

28

Portions of the foregoing and certain following financial presentations in this Compensation Discussion and Analysis include the use of both GAAP (generally accepted accounting principles) and non-GAAP financial measures. We use these financial measures to monitor and evaluate our on-going performance and allocate resources, and we believe that these additional non-GAAP measures are useful to investors for financial analyses of Farmers. Reconciliations of such non-GAAP financial measures to the most directly comparable GAAP financial measure can be found on Appendix A to this proxy statement.

Significant Compensation Actions in 2017

During 2017, we evaluated all of our compensation programs, policies and payouts and concluded that overall our compensation structure continues to align well with our pay-for-performance focus and continues to promote long-term shareholder value, so we maintained the general structure of our compensation programs. The following is a summary of significant actions that occurred in 2017:

Annual Incentive Compensation

Long-term Incentive Compensation

29

Long-Term Incentive Compensation 2015-2017 Vesting Summary

Compensation Committee’s Philosophy on Executive Compensation

Farmers’ goal is to hire and retain an executive management team which we believe will promote both short-term and long-term institutional success. We seek to achieve this goal by providing a fair, competitive compensation package that includes performance-based, at-risk pay components aligned with strategic and financial performance objectives in order to drive our annual and long-term performance, which ultimately aligns with long-term shareholder value. We also seek to implement a compensation program that appropriately balances risk and financial results so that our compensation programs maintain our overall safety and soundness.

The principal elements of each named executive officers’ compensation currently consist of base salary, annual cash incentive compensation and long-term incentive compensation. Like other employees, the named executive officers also receive matching contributions to

30

their 401(k) retirement plan accounts. At our 2017 Annual Meeting, shareholders adopted and approved the 2017 Equity Incentive Plan, which allows the Compensation Committee to continue using equity-based awards as our additional long-term incentive compensation component.

The Role of the Compensation Committee in Determining Executive Compensation

The Compensation Committee oversees the compensation of our named executive officers and establishes our executive compensation philosophy, policy, elements and strategy and reviews proposed executive compensation plans and arrangements, including employment and severance arrangements with our executives. In addition, the Compensation Committee evaluates the performance of our executive officers in order to determine appropriate compensation adjustments as well as future compensation decisions. The Compensation Committee also reviews overall corporate policy regarding compensation and benefit programs that are generally available to all employees and may make recommendations concerning those programs.

Although the Compensation Committee has authority to approve individual compensation arrangements, for example employment contracts and individual incentive award goals, as well as authority to engage legal advisors and compensation consultants for advice about compensation issues, the Compensation Committee does not act entirely autonomously in considering and implementation of our compensation plans. For example, the Compensation Committee recommends the terms of plans such as our 2017 Equity Incentive Plan, subject to final approval of the full independent Board of Directors. At the Compensation Committee’s request, management may provide financial, tax, accounting, or operational information relevant to Compensation Committee deliberations.

Role of Compensation Consultant

As permitted by the Compensation Committee Charter, the Compensation Committee has engaged Pay Governance, LLC (“Pay Governance”) as its outside independent compensation consultant since 2011. Pursuant to the terms of its engagement by the Compensation Committee, Pay Governance generally reviews, analyzes and provides advice regarding our executive compensation and director compensation programs in relation to the objectives of those programs, including comparisons to designated peer group companies and to “best practices,” and also provides information and advice on competitive compensation practices and trends, along with specific views on our compensation programs. In its role as our independent compensation consultant, representatives of Pay Governance engaged in discussions with the Compensation Committee and responded on a regular basis to questions from the Committee and the Committee’s other advisors, providing them with its opinions with respect to the design and implementation of current or proposed compensation programs. During fiscal 2017, Pay Governance reported directly to the Compensation Committee and the Committee retains the sole authority to retain or terminate Pay Governance. Pay Governance did not provide additional services to the company or its affiliates in an amount in excess of $120,000 during 2017.

Compensation Consultant Independence

The Compensation Committee has the responsibility to consider certain independence factors before selecting compensation consultants and other compensation advisers. In connection with the foregoing, the Compensation Committee reviewed, considered and

31

discussed the relevant factors established by NASDAQ to determine such independence, both through surveying Pay Governance and by soliciting input from members of the Compensation Committee through our annual director and officer questionnaires. Based on its review, consideration and discussion, the Compensation Committee determined that the work performed and to be performed by Pay Governance as the Committee’s compensation consultant has not raised and does not raise any conflict of interest, and also determined that Pay Governance qualifies as independent for purposes of the Exchange Act and revised NASDAQ Corporate Governance Requirements.

Say-on-Pay Consideration

At the Company’s 2017 Annual Meeting of Shareholders, our shareholders approved on an advisory basis the executive compensation of our named executive officers as disclosed in the proxy statement for that Annual Meeting, with 93% of the Common Shares represented by shareholders present in person or represented by proxy at the 2017 Annual Meeting voting “for” such approval. The Compensation Committee evaluated the results of this strongly supportive advisory vote, together with the other factors and data discussed in this Compensation and Discussion Analysis, in determining Farmers’ executive compensation policies, making executive compensation decisions, and continuing implementation of the Committee’s compensation philosophy and objectives.

Peer Group Evaluation and Executive Compensation Benchmarks

The Compensation Committee has generally evaluated compensation practices at similarly situated financial institutions to help determine the levels of compensation for financial services executives in our geographic market. In addition, the Compensation Committee does not have a practice of adhering to a strict formula in order to determine executive officer compensation packages rather has relied on a variety of factors including experience, responsibility, individual performance and our overall financial performance. However, given the competitive nature of the financial services industry in general, and the fact that we compete in a primary market with regional and national banking organizations that are significantly larger and that can provide more attractive compensation packages to top executive talent, the Compensation Committee recognizes the need to provide competitive overall compensation opportunities to retain our high-performing executives and attract new executive talent.

During 2015, the Compensation Committee, with the assistance of Pay Governance, undertook an extensive re-evaluation of our peer group and assessed the need to change the composition of Farmers’ peer group to reflect a significant increase in the size of Farmers due to two acquisitions, to better reflect similarly situated financial institutions for purposes of determining competitive market positioning for executive compensation determinations. The Compensation Committee used several factors to identify, evaluate and select peer financial institutions including, but not limited to, (i) factors of size (e.g., assets (ranging from approximately $1 billion to $4 billion), revenues, employees and market capitalization), (ii) factors of profitability and growth (e.g., net revenue and operating income), and (iii) geographic location. The Compensation Committee continued to utilize the following remaining peer group of 17 companies for calendar year 2017 to evaluate the

32

competitiveness of our pay structures and levels, taking into account acquisitions of previously included institutions (the “2017 Peer Group”):

2017 Named Executive Officers Compensation

Base Salary

Base salaries are intended to reward the named executive officers based upon their roles with us and for their performance in those roles. For each named executive officer, their base salaries are reviewed annually subject to adjustments based upon our financial performance, the individual performance of the particular executive, and our overall compensation philosophy of providing base compensation levels for our executive officers within 10% of the median of our 2017 Peer Group. The Compensation Committee conducts an annual evaluation of the performance of Mr. Helmick in light of specified goals and objectives with input from each independent director. Based on such evaluation and input, the Compensation Committee determines the compensation of Mr. Helmick and discusses its determination with all independent directors. All other executive officers are evaluated on a variety of factors including leadership performance, strategic planning and execution, communication abilities, business knowledge, and awareness and accountability. Based thereon, Mr. Helmick determines whether a base salary increase or decrease is considered to be merited based upon individual performance and presents his base salary adjustment recommendations to the Compensation Committee. For 2017, the Compensation Committee determined to increase Mr. Helmick’s base salary from $400,000 to $430,000, an increase of 7.5%, effective April 1, 2017. As a result of the other executive officer evaluations and recommendations by Mr. Helmick, the following merit-based base salary adjustments were made in 2017 for the remaining named executive officers: (i) Mr. Culp received a base salary increase of approximately 3.1% to $206,300; (ii) Mr. Witmer received a base salary increase of approximately 2.6% to $266,875; (iv) Mr. Graham received a base salary increase of approximately 2.75% to $176,730; and (v) Mr. Gerzina received a base salary increase of approximately 3.0% to $177,088.

Annual Incentive Plan

The Compensation Committee believes that performance-based annual cash incentives are an effective way to compensate executives for working together as a team to achieve short-term specific financial goals which the Compensation Committee and management have established as near-term drivers of our long-term success, as well as certain individualized goals specific to an executive’s role and duties. The following is a discussion of the annual cash incentive program implemented by the Compensation Committee during 2017.

The Annual Incentive Plan is intended to foster superior financial results by providing equitable and attainable corporate-wide incentives that reward individual and team efforts to

33

achieve specified performance objectives as determined and applied each fiscal year. The program provides our executive officers and certain non-executive employees the opportunity to receive annual cash incentive payments based upon achievement of such corporate and individual performance goals. Our full-time and part-time, regular, non-commissioned-based associates and executives, as well as those of our subsidiaries, are generally eligible to participate in the Annual Incentive Plan.

In 2017, the Compensation Committee established the target bonus opportunities under the Annual Incentive Plan for each eligible named executive officer expressed as a percentage of base salary. The following table sets forth such target bonus opportunities for each participating named executive officer:

Payments under the Annual Incentive Plan are contingent primarily on the achievement of pre-established performance goals relating to objective financial metrics established for each participating named executive officer by the Compensation Committee, and secondarily upon the results of a subjective evaluation of each individual executive’s performance. Each of the elements has an assigned weight and each of the objective financial criteria has a specific target or goal for the year. In the event that we (or the individual participant) do not meet the specified goal or target for a particular metric, then no compensation will be paid with respect to that objective portion of the Annual Incentive Plan.

The Compensation Committee established a threshold payout of 50% of target opportunity upon attaining a threshold level of the objective metrics, a target payout of 100% upon attaining 100% of the target level of the objective metrics, and a maximum payout of 150% of target opportunity upon attaining at or greater than a maximum level of the objective metrics. For performance falling within each of the percentile ranges, payouts are made on an interpolated basis.

In establishing the Annual Incentive Plan’s objective metrics and targets for 2017, the Compensation Committee utilized the Company’s budgeting model to set the performance at levels that were determined to be achievable with strong management performance. All named executive officers were allocated certain weightings of three core corporate financial measures: earnings per share (“EPS”), return on average assets (“ROA”), and efficiency ratio. Those were the sole objective performance criteria allocated to Messrs. Helmick, Culp, and Witmer. The named executive officers other than Messrs. Helmick, Culp, and Witmer had significant additional objective metrics based on their specific areas of responsibility and oversight. Finally, in addition to the objective performance metrics, a subjective metric was included for each of the named executive officers other than Mr. Graham and Mr. Gerzina, with a weighting of 20% of the total bonus opportunity. The following tables set forth the

34

applicable objective performance metrics, weightings, targets and percentage payouts for each of the named executive officers under the Annual Incentive Plan in 2017:

Kevin J. Helmick, Carl D. Culp and Mark R. Witmer

Mark L. Graham

Joseph A. Gerzina

As indicated above, in addition to the objective performance metrics, the Compensation Committee included a subjective metric for each of the named executive officers other than Mr. Graham and Mr. Gerzina weighted at 20% of the total bonus opportunity for each executive officer. Payouts under this subjective metric were based on evaluations of overall job performance during 2017 using an extensive performance review scorecard for each executive. For each named executive officer other than Mr. Helmick, the scorecards were completed by Mr. Helmick and he provided the basis of his evaluations to the Compensation Committee for the subjective portion of the executive’s bonus for 2017. For Mr. Helmick, each member of the Board of Directors provided input on Mr. Helmick’s performance, which was considered by the Compensation Committee in reaching a determination with respect to the subjective element of Mr. Helmick’s 2017 annual bonus. Based upon such reviews and recommendations, the Compensation Committee approved the following percentage payouts

35

with respect to the subjective element of the total bonus opportunity: (i) Mr. Helmick, 100% of the possible 20% weighting; (ii) Mr. Culp, 100% of the possible 20% weighting; and (iii) Mr. Witmer, 100% of the possible 20% weighting.

Finally, the Compensation Committee continued to include a circuit breaker in the 2017 Annual Incentive Plan, based on Farmers’ “Texas ratio” for the year. The Texas ratio is determined by dividing the amount of Farmers Bank’s non-performing loans, other real estate owned, and loans delinquent for more than 90 days, by Farmers Bank’s tangible capital equity plus its loan loss reserves. If this ratio exceeds 20% for the year, no bonuses are payable under the Annual Incentive Plan. Farmers’ Texas ratio for 2017 was 3.35%, well below this circuit breaker level. The Compensation Committee believes that the use of a circuit breaker in our annual bonus program helps maintain minimum levels of safety and soundness of our institution in the context of providing appropriate near-term incentives for achieving superior financial performance objectives.

As a result of the performance of Farmers with respect to the above-described objective metrics and each named executive officer’s individual performance evaluations, the Compensation Committee awarded the following payouts with respect to 2017 performance under the Annual Incentive Plan:

Long-Term Incentive Compensation Plans

In 2011, the Board of Directors first approved a long-term cash incentive compensation plan (the “LTI Cash Program”) under which our executive officers and certain other employees are eligible to receive awards for possible long-term cash incentive payments based on the achievement of prescribed corporate and/or individual performance metrics. The purpose of the LTI Cash Program is to foster and promote Farmers’ long-term financial success and value by motivating performance through long-term incentive compensation, pending review and approval by the Compensation Committee. The LTI Cash Program is also intended to attract and retain the services of talented individuals and motivate participants to achieve performance objectives that promote sound and financially healthy growth. The LTI Cash Program may continue until terminated by the Board of Directors.

The 2012 Equity Incentive Plan was adopted by our Board of Directors and shareholders to promote Farmers’ long-term financial success and increase shareholder value by motivating performance through equity-based long-term incentive compensation. The 2012 Equity Incentive Plan was also intended to encourage participants to acquire ownership interests in the Company, attract and retain talented executives and directors, and enable participants to participate in the Company’s long-term growth and financial success. During 2017, the Board of Directors and Farmers’ shareholders adopted the 2017 Equity Incentive Plan to continue these philosophies and long-term compensation opportunities.

36

In 2015, the Compensation Committee established the target award opportunities under the LTI Cash Program and 2012 Equity Incentive Plan for each eligible named executive officer expressed as a percentage of a participant’s base salary and established that each executive’s total long-term incentive opportunity would be based on two performance metrics for the three-year performance period commencing in the year of the grant and ending on December 31, 2017 (“Performance Period”) at “target,” “threshold” or “maximum” performance levels. For performance falling below threshold, no award payout or vesting was to occur. The following table sets forth the target long-term incentive compensation opportunities for each participating named executive officer at the time of grant in 2015:

The corporate performance metrics and weightings established in 2015 by the Compensation Committee for the LTI Cash Program and the 2012 Equity Incentive Plan, respectively, were: (i) relative TSR, at a weighting of 30%; and (ii) relative average ROE, at a weighting of 70%, each expressed as a percentile based on a comparison of the performance of Farmers relative to the performance of the peer group established in 2015 during the Performance Period. The following table indicates the threshold, target and maximum performance levels (for performance falling within each of the percentile ranges, payout or vesting was to occur on an interpolated basis) and the results of our relative TSR and relative average ROE performance, as adjusted, for the Performance Period, with the percentage payouts for the LTI Cash Program and 2012 Equity Incentive Plan awards granted in 2015. Percentage payout opportunities for the cash-based awards under the LTI Cash Program ranged from 50% vesting for performing at the threshold 50^th percentile of peer group, to 250% vesting for performing at or above the 85^th percentile. The share-based awards under the 2012 Equity Incentive Plan were granted at the maximum payout level of 225% of target opportunity, and percentage payout opportunities ranged from 22% vesting for performing at the threshold 50^th percentile of peer group (equivalent to 50% of target opportunity), to 100% vesting for performing at or above the 85^th percentile (equivalent to 225%, or maximum, of target opportunity). The following table summarizes the percentage payouts for our 2015 long-term performance awards. Although the Compensation Committee has certified performance and vesting levels for the 2015 long-term performance awards, the awards will not be settled until April 17, 2018. Payout amounts under the LTI Cash Program for each named executive officer are included in “Non-Equity Incentive Plan Compensation” column (g) of the Summary Compensation Table located on page 44 of this proxy statement.

Vesting Summary of 2015-2017 Long-Term Performance Awards

37

In 2017, the Compensation Committee established the long-term incentive compensation target opportunities for each eligible named executive officer under our LTI Cash Program and our 2017 Equity Incentive Plan, expressed as a percentage of base salary at the time of grant, as follows:

In conjunction with establishing the target long-term incentive opportunity for our executive officers, the Compensation Committee, determined to allocate 25% of our total long-term compensation opportunity to service-based awards, subject to three-year cliff vesting. We allocated the remaining 75% to performance-based awards, for which we continued to use relative TSR and relative average ROE as the performance metrics, with the same mix of cash-based and equity-based long-term incentive awards as follows: (i) 25% in cash-based awards under our LTI Cash Program subject to vesting based on relative TSR compared to our peer group over a Performance Period ending December 31, 2019, and (ii) 50% in equity-based grants under our 2017 Equity Incentive Plan subject to vesting based on relative average ROE compared to our peer group over a Performance Period ending December 31, 2019.

The following table indicates our intended payouts at the threshold, target and maximum levels for our 2017 long-term incentive awards under both the LTI Cash Program and the 2017 Equity Incentive Plan, with relative performance compared to our 2017 Peer Group. The maximum award opportunity was established at 200% of the target opportunity.

For performance falling within each of the percentile ranges, payouts or vesting will occur on an interpolated basis. The amounts of the threshold, target and maximum award payouts or vesting that may be received by each of our named executive officers upon completion of the 2017-2019 Performance Period with regard to long-term incentive awards granted in 2017 under the LTI Cash Program and the 2017 Equity Incentive Plan is described in detail in the Grants of Plan Based Awards table located on page 46 of this proxy statement.

Clawback Policy

Farmers has adopted a clawback policy as part of its Incentive Compensation Guidelines. Pursuant to that policy, if the Company is required to restate all or a significant portion of its

38

financial statements, the Board is empowered, in its discretion, to require reimbursement of all or any portion of bonuses paid or incentive compensation awarded to any participant in an incentive compensation program (including equity-based awards), and/or effect the cancellation of all or any portion of unpaid awards which may be paid to such participants if: (a) the amount of the bonus or incentive compensation was calculated based on the achievement of financial results that were subsequently the subject of a material restatement, and (b) the amount of the bonus or incentive compensation that would have been awarded to the participant, had the financial results been properly reported, would have been lower than the amount actually awarded. The Company acknowledges under this policy that it is not intended to add any forfeiture obligations or financial responsibilities to the Chief Executive Officer or Chief Financial Officer which are in addition to, or duplicative of, those obligations arising under Section 304 of the Sarbanes-Oxley Act of 2002.

Furthermore, if a participant in any incentive compensation program engages in misconduct related to such program, regardless of whether any restatement of financial statements is required as a result thereof, the Board shall take such actions as it considers appropriate to address the misconduct. Such actions may include cancellation of any unpaid portion of incentive compensation awarded to such participant, reimbursement of any incentive compensation paid to such participant, and other disciplinary actions.

401(k) Plan and Company Contributions

All of our employees who have completed at least one year of service and meet certain other eligibility requirements are eligible to participate in our 401(k) Profit Sharing Retirement Savings Plan (the “401(k) Plan”). Under the terms of the 401(k) Plan, employees may voluntarily defer a portion of their annual compensation, subject to applicable federal restrictions and deferral limitations, and Farmers Bank matches a percentage of each participant’s voluntary contributions, up to 6% of gross wages. In addition, at the discretion of the Board of Directors, Farmers Bank may make an additional profit sharing contribution to the 401(k) Plan. During 2017, Farmers Bank provided 401(k) Plan matching contributions of 50% for each of the named executive officers (subject to a maximum of 3% of gross wages), but no additional profit sharing contributions were made.

Nonqualified Deferred Compensation Plan

In 2015, we adopted an unfunded nonqualified retirement plan for certain of our executive officers (the “Nonqualified Plan”) pursuant to which such officers may voluntarily defer a greater portion of their compensation than permitted by applicable federal restrictions and deferral limitations in our 401(k) Plan. Participating officers are at all times 100% vested in their voluntary deferrals. The Company may also provide matching or discretionary credits to the accounts of eligible officers, as determined by the Company in its sole discretion. The Company currently intends to credit matching contributions equal to 50% of each participant’s voluntary deferrals to the Nonqualified Plan, up to 6% of gross wages (or a 3% match). Any matching or discretionary credits under the Nonqualified Plan vest and become non-forfeitable in accordance with a specified formula that provides for partial vesting starting after completion of two years and full vesting after six years. Upon a Change-in-Control (as defined in the Nonqualified Plan), participants’ benefits under the Nonqualified Plan become fully vested and non-forfeitable. Benefits under the Nonqualified Plan represent unsecured general obligations of the Company to pay participating officers at some time in the future.

During 2017, we amended the Nonqualified Plan to allow for discretionary additional annual contributions by the Company for the benefit of eligible participating officers, based

39

on a percentage of each participant’s total eligible compensation, as determined in the discretion of the Compensation Committee. With respect to calendar year 2017, the Compensation Committee approved a discretionary contribution in the amount of 2%.

The amounts accrued pursuant to the Nonqualified Plan for the benefit of our named executive officers for fiscal year 2017 are disclosed in the Summary Compensation Table located on page 44 of this proxy statement. The Compensation Committee believes that maintaining this Nonqualified Plan helps to maintain the competitiveness of our entire executive retirement benefits.

Amounts payable to participating officers under the Nonqualified Plan will be distributed in accordance with the terms of the Nonqualified Plan and elections made by the participating officers. Benefits generally will be paid in a single lump sum unless the participating officer has elected to receive annual installments for a period of up to ten years. The benefits will be paid upon the earliest of a participating officer’s separation from service death or disability unless the participating officer has elected to receive payments as of a specified date (including the earlier of that date or the occurrence of a regular distribution event). The Nonqualified Plan is subject to requirements affecting deferred compensation under Section 409A of the Internal Revenue Code and is being administered in compliance with the applicable regulations under Section 409A.

Perquisites and Other Compensation

Executive officers also participate in broad-based employee benefit plans, such as medical, dental, supplemental disability, retiree health insurance and term life insurance programs. Except for matching contributions in connection with our Nonqualified Plan as described above, and country club memberships provided by Farmers Bank to the named executive officers for customer relationship development purposes, executive officers did not receive in 2017 any perquisites or personal benefits that are not available to all employees. The amounts of these benefits are included in the “All Other Compensation” column (i) of the Summary Compensation Table located on page 44 of this proxy statement.

Other Elements of Our Compensation Programs

Employment Agreements, Separation Policy and Change in Control Arrangements

The Compensation Committee carefully considers the use and conditions of any employment agreements. The Compensation Committee recognizes that employment agreements containing severance and change in control arrangements are often appropriate to attract prospective executives who forego significant compensation and opportunities at the companies they are leaving, or who face relocation expenses in order to accept employment. Generally, executives are not willing to accept such risks and costs without protection in the event that their employment with us is terminated due to unanticipated changes, including a change in control.

Farmers first adopted an Executive Separation Policy in 2013 which currently applies to all of our named executive officers. In connection therewith, Farmers entered also into change in control agreements with each of our named executive officers (“Change in Control Agreements”). The material provisions of the Executive Separation Policy and the Change in Control Agreements are discussed under the caption “EXECUTIVE COMPENSATION AND OTHER INFORMATION – Employment Agreements, Change in Control Agreement,

40

Executive Separation Policy” beginning on page 52 of this proxy statement. In connection with the execution of the Change in Control Agreements, each named executive officer that previously had an employment agreement with Farmers (namely, Messrs. Helmick, Culp, and Graham) terminated his existing employment agreement.

Overall, the Compensation Committee believes that the implementation of the Executive Separation Policy and Change in Control Agreements is appropriate to help ensure that Farmers will have the continued dedication, undivided loyalty and objective advice from its key executives, even in the event of a potential transaction which could result in a change in control of Farmers. The Separation Policy offers certain protections in the event of certain terminations of employment, while the Change in Control Agreements provide certain protections in the event of a change in control event, but only if the executive’s employment is terminated as a result of (or within a specified period after) a change in control (i.e., a double trigger). The Compensation Committee does not believe that executives should receive compensation benefits merely as a result of a change in control; rather, it believes that our Change in Control Agreements provide our executive officers with adequate protection to help ensure that change in control offers will be evaluated by our executive officers in the best interests of Farmers and our shareholders without regard to concerns that a transaction could eliminate his or her job without appropriate dispensation. The Compensation Committee recognizes that these agreements may also tend to discourage a takeover attempt as a change in control could trigger increased compensation expense as part of the transaction.

Section 162(m) of the Internal Revenue Code

As applicable for 2017, Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”) placed a limit on the tax deduction for compensation exceeding $1.0 million paid to the chief executive officer and four most highly compensated executive officers of a corporation other than the chief financial officer in a taxable year, but performance-based compensation such as stock-related compensation and performance-based cash bonuses may be exempt from the $1.0 million limit if awarded under a stockholder-approved plan and certain other conditions are satisfied. We expect that all of the compensation paid in 2017 to our named executive officers is deductible. The Board of Directors and the Compensation Committee could, however, award non-deductible compensation as they deem appropriate. Moreover, because of ambiguities in the application and interpretation of Section 162(m) and the regulations issued under Section 162(m), there can be no assurance that compensation intended to satisfy the requirements for deductibility under Section 162(m) actually will be deductible.

The Tax Cuts and Jobs Act, which was adopted on December 22, 2017 and became effective on January 1, 2018, eliminated the performance-based exception to the $1.0 million per-executive annual limit on deductibility of compensation under Section 162(m) and the exclusion of the chief financial officer. While the Compensation Committee and the Board of Directors will continue to determine the level and structure of compensation in the manner they determine to be appropriate in order to attract and retain executive leadership and serve the needs of Farmers and its constituents, such levels and structure of executive compensation will no longer be considered within the framework of the Section 162(m) performance-based exception.

Stock Ownership Guidelines

As part of the Company’s Corporate Governance Guidelines, it has adopted stock ownership guidelines for our directors and executive officers. These guidelines require that,

41

within five years from the date a person first becomes a non-executive director, or within either eight years of March 15, 2016 or 11 years from the date an executive officer is first included as a participant in our Equity Plans (unless, due to specific facts and circumstances, a different period of time is determined to be appropriate by the Corporate Governance and Nominating Committee), the following amounts of Common Shares be owned by that person:

Individuals subject to these guidelines are expected to satisfy certain milestones during the attainment periods to evidence that the individual is making appropriate progress toward achieving their respective ownership amount. In determining compliance with these guidelines, the Compensation Committee considers the beneficial ownership of our executive officers and directors as required to be reported in a proxy statement.

In additional to these requirements, our executive officers and directors are prohibited under our insider trading policy and procedures from pledging our Common Shares, purchasing our Common Shares on margin, engaging in short sales, or engaging in any hedging transaction.

Director Compensation

The Compensation Committee is also responsible for recommending to the Board of Directors compensation for our non-employee directors. Generally, director compensation is structured in a fashion to attract and retain high quality individuals to serve on the Board of Directors, to compensate such individuals for the time and energy expended in providing us their expertise, considering the size, nature and location of Farmers as a bank holding company competing in our markets. On an annual basis, the Compensation Committee requests that its compensation consultant evaluate our current director compensation levels relative to our peers. Generally, it is the overall goal of the Compensation Committee to position director compensation at a median market level. For 2017, the Compensation Committee recommended and the independent members of the Board of Directors approved (a) a general annual director retainer fee of $40,000, and (b) the following retainers for directors with additional duties: (i) $25,000 for the independent Board Chair, (ii) $20,000 for the independent Board Vice-Chair, (iii) $10,000 for the chair of the Executive Committee, and (iv) $5,000 for all other committee chairs.

All director compensation amounts for 2017 are reflected in the Director Compensation table located on page 59 of this proxy statement.

Oversight and Risk Management of Compensation Programs

The Compensation Committee oversees the implementation and enforcement of our policies, procedures and practices related to its various compensation programs as part of its duties. This is designed to monitor our compensation policies to ensure that the compensation packages offered to its employees and executive officers do not present such individuals with the potential to engage in excessive or inappropriate risk taking activities. In addition, the Board Enterprise Risk Management Committee works with the Compensation

42

Committee in order to monitor our compensation policies, procedures and practices, as part of its duties to monitor enterprise-wide risk.

The Compensation and Board Enterprise Risk Management Committees believe that our current compensation structure for employees and executive officers does not encourage unnecessary or excessive risk taking to the extent that it would reasonably likely lead to a material adverse effect. It is the opinion of the Compensation and Board Enterprise Risk Management Committees that our current compensation programs appropriately balance risk and the desire to focus on our short-term and the long-term goals without encouraging unnecessary or excessive risk taking.

Compensation Committee Interlocks and Insider Participation

During the last completed fiscal year, no member of the Compensation Committee was an officer or employee of Farmers or any of our subsidiaries, or was formerly an officer of Farmers or any of our subsidiaries. None of our directors had any business or financial relationship with us requiring disclosure in this proxy statement.

THE COMPENSATION COMMITTEE REPORT

The Compensation Committee has reviewed and discussed this Compensation Discussion and Analysis with Farmers’ management. Based upon this review and discussion, the Compensation Committee recommends to the Board of Directors that this Compensation Discussion and Analysis be included in this proxy statement and our Annual Report on Form 10-K.
