Voluntary Electronic Receipt of Future Proxy Materials

First Financial is committed to conducting business safely and sustainably.

​ |  | ​ | ​ | reducing the emission of approximately 39,900 million fewer pounds of greenhouse gases, including CO2, or the equivalent of 3.6 automobiles running for one year | ​ | ​ |  | ​ | ​ | using approximately 56.6 million fewer BTUs, or the equivalent of the amount of energy used by 67 residential refrigerators for one full year | ​

Questions and Answers about this Proxy Statement and the Annual Meeting
​
Why am I receiving this Proxy Statement?
We are making available this Notice of Annual Meeting of Shareholders, Proxy Statement, and 2024 Annual Report (the “proxy materials”), either online or by mail, in connection with the Annual Meeting because you were a shareholder of record of the Company as of the close of business on March 28, 2025 (the “record date”). This Proxy Statement describes the matters on which you are asked to vote and provides information about those matters and about the Company so that you can make an informed decision.
This Proxy Statement and related materials are being mailed to, or can be accessed online by, shareholders on or about April 17, 2025.
What is Notice and Access and why did First Financial elect to use it?
We are making the proxy materials available to our shareholders electronically via the Internet under the Notice and Access regulations of the U.S. Securities and Exchange Commission (“SEC”). Many of our shareholders have received a Notice of Internet Availability of Proxy Materials (“Notice of Internet Availability”) in lieu of receiving a full set of printed materials in the mail. We are using the Notice and Access method to expedite distribution and reduce the costs associated with printing and mailing these materials.
The Notice of Internet Availability includes information on how to access and review the proxy materials and how to vote online, by phone, or by attending the Annual Meeting virtually via the Internet. The proxy materials, as well as other reports filed with or furnished to the SEC, can be accessed free of charge at www.bankatfirst.com/about/investor-relations.html. You may also access this information via “Search Filings” at www.sec.gov.
I received a Notice of Internet Availability of Proxy Materials only. How can I receive printed copies of the proxy materials?
Shareholders may receive a printed copy of the proxy materials, free of charge, by following the instructions on the Notice of Internet Availability for receiving such materials.
Who is paying for the cost of this proxy solicitation?
First Financial is paying for the costs associated with preparing, printing and mailing these proxy materials. In addition, we will reimburse banks, brokers and other custodians, nominees and fiduciaries for reasonable expenses incurred in forwarding the proxy materials to beneficial owners of our shares and soliciting their proxies.
Our directors, officers and associates also may solicit proxies from our shareholders by further mailings, personal contact, phone, or e-mail, but these individuals will not receive additional compensation for this solicitation activity.
Who can vote at the Annual Meeting?
Only shareholders of record at the close of business on March 28, 2025 will be entitled to notice of and to vote at the Annual Meeting. Each common share owned at the close of business on March 28, 2025 entitles its owner to one vote on each proposal being considered at the Annual Meeting.
The common shares are the Company’s only voting securities entitled to vote at the Annual Meeting. At the close of business on March 28, 2025, there were 95,276,004 common shares outstanding and entitled to vote.

TABLE OF CONTENTS
How do I vote my shares?
Even if you plan to attend the Annual Meeting virtually via the Internet, as described below, we strongly encourage you to vote prior to the meeting. Shareholders of record may vote using any of the following methods:
Online Voting: You may vote before or during the meeting through the Internet as instructed on your Notice of Internet Availability or proxy card. Before the Annual Meeting, you may go to http://www.proxyvote.com or scan the QR Barcode appearing on the Notice of Internet Availability to transmit your voting instructions up until 11:59 p.m. Eastern Time on May 26, 2025. During the meeting, you may go to www.virtualshareholdermeeting.com/FFBC2025 to attend the meeting via webcast and vote online. You should have your proxy card or Notice of Internet Availability in hand when you access either of these websites and follow the instructions to obtain your records and to vote.
Vote by Phone: Telephone voting is available toll-free at 1-800-690-6903 up until 11:59 pm Eastern Time on May 26, 2025. You should have your proxy card or Notice of Internet Availability in hand when making this call.
Vote by Mail: Complete, sign and date your proxy card and return it in the envelope we have provided or return it to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717. Proxy cards must be received by 11:59 p.m. Eastern Time on May 26, 2025.
If you hold your shares in “street name” at a bank, broker or other nominee, you should follow the instructions provided by your bank, broker or other nominee on how to vote your shares.
What is the difference between holding shares directly as a shareholder of record and holding shares in “street name” at a bank, broker or other nominee?
Shareholder of Record: If your shares are registered directly in your name with our transfer agent, Computershare Shareholder Services, you are considered the shareholder of record and the proxy materials or a Notice of Internet Availability were sent directly to you. As the shareholder of record, you have the right to grant your voting proxy directly by using the proxy card, through the online voting methods described in this Proxy Statement, by phone, or by voting electronically during the Annual Meeting.
Holding shares in “street name” at a bank, broker or other nominee: If your shares are held by a bank, broker or other nominee, you are considered the beneficial owner of shares held in “street name.” The proxy materials, Notice of Internet Availability, or voting instruction card was forwarded to you by your bank, broker or other nominee who is considered the shareholder of record of your shares. Your bank, broker or other nominee will send you, as the beneficial owner, separate information describing how you can vote your shares.
What happens if I sign, date and return my proxy card, or complete the online or telephonic proxy methods, but do not specify how I want my shares voted on one or more of the proposals?
Your shares will be voted in the manner you specify on each proposal. If you are a shareholder of record and sign, date and return a proxy or submit a proxy online or by telephone, but do not provide voting instructions on one or more proposals, your vote will be counted as a vote “for” all of the Company’s director nominees and “for” Proposals 2 and 3.
If you hold your shares in “street name” and have not returned voting instructions on one or more proposals, your bank, broker or nominee may vote your shares only on those proposals for which it has discretion to vote. We believe that under applicable rules, your bank, broker or nominee has discretion to vote your shares on the ratification of our independent registered accounting firm (Proposal 2), which is considered a routine matter. However, your bank, broker or nominee does not have discretion to vote your shares on certain other matters considered non-routine such as the election of directors (Proposal 1) or the advisory approval of executive compensation (Proposal 3). If you do not provide voting instructions on a non-routine proposal, your shares will be considered “broker non-votes.” The effect of a “broker non-vote” on each proposal is detailed in the questions and answers under the heading “What proposals are being considered and how many votes are needed for each proposal to be approved by the shareholders” on page 11.

TABLE OF CONTENTS
What if I indicate “Withheld” with respect to the election of one or more directors or “Abstain” with respect to any of the other proposals being considered?
The effect of these voting specifications on each proposal is detailed in the questions and answers under the heading “What proposals are being considered and how many votes are needed for each proposal to be approved by the shareholders” on the next page.
Can I change my proxy vote?
You may revoke your proxy at any time before it is actually exercised at the Annual Meeting by:
▪
Sending a written notice of revocation to First Financial Bancorp., Attn: Karen B. Woods, Corporate Secretary, 255 East Fifth Street, Suite 2900, Cincinnati, Ohio 45202;
​
▪
Delivering a later-dated proxy (including by using the online or telephone voting methods); or
​
▪
Attending the virtual Annual Meeting and giving notice of revocation electronically during the meeting.

What is “householding?”
Under the rules adopted by the SEC, we may deliver a single set of proxy materials to one address shared by two or more of our shareholders.

To take advantage of this opportunity, we may deliver only one set of proxy materials to multiple shareholders who share an address, unless we received contrary instructions from the impacted shareholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the proxy materials, as requested, to any shareholder at the shared address to which a single copy of these documents was delivered. If you prefer to receive separate copies of the proxy materials, contact Broadridge Financial Solutions, Inc. by calling 1-866-540-7095 or in writing at 51 Mercedes Way, Edgewood, New York 11717, Attention: Householding Department. In addition, if you currently are a shareholder who shares an address with another shareholder and would like to receive only one copy of future notices and proxy materials for your household, you may notify your broker if your shares are held in a brokerage account or you may notify us if you hold registered shares. Registered shareholders may notify us by contacting Broadridge Financial Solutions, Inc. at the above telephone number or address.

TABLE OF CONTENTS​
Proposal 1 — Election of Directors
​
As of the record date, our Board consisted of eleven members, ten of whom were non-employee directors and considered “independent,” as defined by the Nasdaq Rules. In March 2025, Cynthia Booth notified the Company of her intention to retire from the Board effective as of the date of the 2025 Annual Meeting. Ms. Booth’s retirement did not result from any disagreement between the Company and Ms. Booth. Also in March 2025, the Board approved, in accordance with the Company’s Amended Regulations, to decrease the Board to ten members, effective as of the Annual Meeting, opting not to fill the seat vacated by Ms. Booth at this time. The Board is actively engaged in the recruitment of additional directors, and may expand the size of the Board and fill the vacancy created by that expansion if it identifies a director candidate or candidates prior to the 2026 Annual Meeting of Shareholders. If the size of the Board is expanded, director candidates may be nominated as permitted by law and our Amended Regulations.
Our Amended Regulations provide that the Board shall consist of not less than nine nor more than 25 persons, with the exact number to be fixed and determined from time to time by resolution of the Board or by resolution of the shareholders at any annual or special meeting of shareholders. As the Board continues to evaluate the appropriate mix of skills, qualifications and attributes of the current Board and the skills needed to position the Board to lead the Company in the future, we anticipate additional directors will retire and new directors will be added from time to time to fill any vacancies. Any vacancy may be filled by the Board in accordance with law and our Amended Regulations for the remainder of the term of the vacant directorship.
Our Board has approved the nomination of the following ten persons as candidates for election as directors at the Annual Meeting, each for a one-year term: Anne L. Arvia, Vincent A. Berta, Archie M. Brown, Claude E. Davis, William J. Kramer, Dawn C. Morris, Thomas M. O’Brien, Andre T. Porter, Maribeth S. Rahe and Gary W. Warzala. The Corporate Governance and Nominating Committee (“CGNC” or the “Governance Committee”) recommended all ten nominees to the Board, which in turn unanimously approved the nomination of all ten persons.
In the event that any one or more of the nominees becomes unavailable or unable to serve as a director prior to the Annual Meeting, your submitted proxy will be voted to elect the remaining nominees and any substitute nominee or nominees designated by the Board. We have no reason to believe that any nominee will be unable or decline to serve as a director.
The ten nominees for director receiving the most votes at the Annual Meeting will be elected as directors. You can find additional information about our Policy on Majority Voting in the Corporate Governance section of this Proxy Statement. The general considerations and criteria for assessing director candidates are established in the Charter of the Governance Committee (available at www.bankatfirst.com/about/investor-relations.html). These considerations and criteria are also summarized in the Corporate Governance section of this Proxy Statement.
This Proxy Statement contains information concerning the director nominees, including their present and past professional positions, current directorships with other companies or organizations, and key qualifications and attributes qualifying them to serve on our Board. The age indicated for each nominee is their age as of March 28, 2025. For information regarding ownership of shares of the Company by nominees and directors of the Company, see the Shareholdings of Directors, Executive Officers and Nominees for Director section of this Proxy Statement. There are no arrangements or understandings between any director nominee and any other person pursuant to which such director nominee is or was nominated to serve as director.

​ | ​ |  | ​ | ​ | ​ | The Board recommends a vote FOR all of the nominees for director. | ​ | ​

TABLE OF CONTENTS​
Report of the Audit Committee
In accordance with its written charter, the Audit Committee oversees the Company’s financial reporting process on behalf of the Board. Management has the primary responsibility for the financial statements and the reporting process, including the systems of internal controls. The Company’s independent registered public accounting firm is responsible for expressing an opinion on the conformity of the Company’s audited financial statements to generally accepted accounting principles and on the Company’s internal control over financial reporting. In this context, the Audit Committee has reviewed and discussed with management and Crowe the audited financial statements for the year ended December 31, 2024, and Crowe’s evaluation of the Company’s internal control over financial reporting. The Audit Committee has discussed with Crowe the matters that are required to be discussed by Auditing Standards No. 16 (Communications with Audit Committees) as amended and adopted by the Public Company Accounting Oversight Board (“PCAOB”) in Rule 3200T.
Crowe has provided to the Audit Committee the written disclosures and the letter required by applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit Committee concerning independence, and the Audit Committee has discussed with Crowe that firm’s independence. The Audit Committee has concluded that Crowe’s provision of audit and non-audit services to First Financial and its affiliates is compatible with Crowe’s independence.
The Audit Committee discussed with the Company’s internal auditors and Crowe the overall scope and plans for their respective audits. The Audit Committee met with the internal auditors and with Crowe, with and without management present, to discuss the results of their examinations, their evaluations of the Company’s internal controls, and the overall quality of the Company’s financial reporting.
In reliance on the reviews and discussions referred to above, the Audit Committee, on February 19, 2025, recommended to the Board, and the Board has approved, that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2024, for filing with the SEC.

TABLE OF CONTENTS​
Proposal 3 — Non-Binding, Advisory Vote to Approve Executive Officer Compensation
​
As required pursuant to Section 14A of the Securities and Exchange Act of 1934, as amended the (“Exchange Act”), we are asking our shareholders to approve, on a (non-binding) advisory basis, the compensation of the Company’s named executive officers (“named executive officers” or “NEOs”) identified in the Summary Compensation Table included in the Executive Compensation portion of this Proxy Statement beginning at page 40. While this vote is advisory, and not binding on our Company, it will provide information to us regarding shareholder sentiment about our compensation principles and objectives and may be considered in future executive compensation related decisions. As determined by our shareholders most recently at the 2023 Annual Meeting of Shareholders, we request this advisory approval each year.
We strongly encourage you to review the Executive Compensation — Compensation Discussion and Analysis section of this Proxy Statement as well as the Summary Compensation Table and other related compensation tables for detailed information about the compensation of our NEOs when making your voting decision on this proposal.
We believe our compensation program has contributed to our Company’s recent and long-term successes. Our compensation philosophy is based on the following guiding principles, which provide that our executive compensation programs:
▪
Drive alignment between Company strategy, executive pay, and shareholder value creation;
​
▪
Drive alignment between an executive’s performance and the interests of shareholders by tying compensation to our Company’s performance, also known as “Pay for Performance;”
​
▪
Attract, motivate, and retain key talent to deliver consistent, long-term performance; and
​
▪
Incorporate proper governance practices to prevent or mitigate inappropriate risk-taking.
​
We believe information provided in the Executive Compensation portion of this Proxy Statement demonstrates that our executive compensation program has been designed appropriately to ensure our management’s interests are aligned with our shareholders’ interest to support long-term value creation and to differentiate pay based on our performance within our peer group.
Your vote is requested on the following resolution:
RESOLVED, that the shareholders of First Financial Bancorp. approve, on an advisory basis, the compensation of the Company’s named executive officers disclosed in the Compensation Discussion and Analysis, the Summary Compensation Table and the related compensation tables, notes and narrative in the Proxy Statement for the Company’s 2025 Annual Meeting of Shareholders.

​ | ​ |  | ​ | ​ | ​ | The Board of Directors recommends a vote FOR the approval of the advisory resolution on executive compensation. | ​ | ​

Delinquent Section 16(a) Reports
Section 16(a) of the Securities Exchange Act of 1934 requires officers, directors and persons who own more than 10 percent of First Financial’s common shares to file reports of ownership and changes in ownership on Forms 3, 4 and 5 with the SEC.
Based solely on a review of the copies of these Forms 3, 4, and 5 that are publicly available on the SEC’s EDGAR filing system and written representations from certain reporting persons that they were not required to file a Form 5 for the specific fiscal year, First Financial believes that all of its officers, directors and greater than 10 percent shareholders complied with all filing requirements applicable to them with respect to transactions completed in 2024, except for Malcolm Myers who filed an amended Form 3 on March 18, 2024, to report a holding that was omitted from his initial Form 3 filed on March 5, 2024.

Corporate Governance
​
General
At First Financial we are committed to conducting business in accordance with our Corporate Strategy, which defines our purpose.
Our Corporate Strategy and our Code of Conduct guide us in managing our business in line with high standards of business practices and in the best interest of our shareholders, clients, associates and stakeholders.
Code of Conduct
Our Board has adopted a Code of Conduct that applies to everyone at First Financial: our directors, officers and associates. The Code of Conduct identifies our commitment to our values and our responsibilities to our stakeholders, including our clients, our shareholders, our fellow associates, our regulators, and our communities. The Code of Conduct provides guidance on compliance with laws and regulations, non-discrimination, equal opportunity, maintaining a respectful workplace that fosters our culture, protecting Company assets and confidential information, conflicts of interest, accuracy of records and information reporting, and our responsibilities to the communities in which we conduct business. The Code of Conduct also encourages associates to report any illegal or unethical behavior. All newly hired associates are required to certify that they have reviewed and understand the Code of Conduct. In addition, each year all associates receive training and are asked to affirmatively acknowledge their obligation to follow the Code of Conduct.
Code of Ethics for the CEO and Senior Financial Officers
Our Board has also adopted a Code of Ethics for our chief executive officer and senior financial officers that provides further guidance about their responsibilities for full, fair, accurate, timely and understandable disclosure in the periodic reports we file with the SEC.
Corporate Governance Principles
We believe that effective corporate governance is built on adherence to a number of  “best practices.” These practices are consistent with the Board’s responsibilities to effectively oversee the Company’s strategy, evaluate and compensate Company executives, and plan for management succession. Most importantly, these practices are believed to

TABLE OF CONTENTS​
strengthen the Company and protect our shareholders’ interests. Accordingly, the Board has developed and follows our Corporate Governance Principles to set forth common procedures and standards relating to corporate governance. The Corporate Governance Principles cover, among other things, board composition, executive sessions of the Board, director qualifications, director responsibilities, director independence, voting for directors, limitations on membership on other boards, continuing education for members of the Board, and Board performance evaluations.
Policies and Procedures Relating to Complaints
The Audit Committee has approved procedures for the receipt, retention and treatment of reports or complaints to the Audit Committee regarding accounting, internal accounting controls, auditing matters and legal or regulatory matters. These procedures also provide for the submission by associates of confidential, anonymous reports to the Audit Committee of concerns regarding questionable accounting or auditing matters.

Our Board’s Role in Risk Oversight
Assessing and managing risk is the responsibility of the Board and management of First Financial. Our Board, with the assistance of the Enterprise Risk and Compliance Committee and other Board committees as discussed below, reviews and oversees our Enterprise Risk Management (“ERM”) program, which is designed to enable effective and efficient identification, assessment, measurement and management of critical enterprise risks and to align risk appetite and strategy. The ERM program was established to clearly define risk management roles and responsibilities, bring together senior management to discuss risk and promote visibility and constructive dialogue around risk at all levels of the organization, enhance risk response decisions, and reduce the potential for operational losses.
The Company’s risk governance structure starts with each line of business being responsible for managing its own risks. The Company employs a second line to monitor and provide support to the lines of business while aggregating risks of a similar nature horizontally across units within the organization (e.g., credit, reputation, operational), and a third line internal audit function. Various risk-related committees whose members are comprised of representatives from the lines of business, risk management, audit, and senior management report to the Enterprise Risk Management Committee (“ERMC”). The ERMC, comprised of executive and senior management, serves as the central body for overseeing, evaluating, and recommending policies and solutions to address both existing and emerging risks. The ERMC is also responsible for evaluating the effectiveness of mitigating and compensating controls, ensuring the adequacy of risk remediation plans, and monitoring risk management efforts across the business.
The Board and executive management have appointed a Chief Risk Officer (CRO) to assist with the risk-oversight responsibilities of the Board and its committees. The Chief Risk Officer provides the Board with a quarterly risk profile, which includes reports on the risk level and trend of each identified risk discipline of the Company, comparing these trends to the Board-established risk appetites and tolerances. Under the ERM program, management develops a comprehensive risk portfolio by facilitating business and function risk assessments, performing targeted risk assessments, and gathering information on specific risk categories and controls gathered from various internal Company operations. Based on these assessments, management develops response plans for risks or controls identified as requiring focused attention. Management provides regular reports on the existing and emerging risk portfolio, response plans, and monitoring efforts to the ERMC and to the Enterprise Risk and Compliance Committee of our Board.
Risk and Cybersecurity
In addition to its general responsibility for monitoring and assessing Company risks and controls, the Enterprise Risk and Compliance Committee of the Board oversees the Company’s efforts to address increasing cyber and technology-related risks, including those associated with Artificial Intelligence (AI). The Company is actively exploring and implementing AI governance frameworks to ensure ethical, transparent, and responsible use of AI technologies, while managing associated risks. The Company’s Chief Information Security Officer chairs the Cybersecurity ERM Committee, attends quarterly ERMC and the Board Enterprise Risk and Compliance Committee meetings, and provides regular reports on the Company’s cybersecurity risks and framework. An annual comprehensive cybersecurity report is also presented

​ | 28 | ​ | ​ | 2025 Proxy Statement | Corporate Governance | ​

TABLE OF CONTENTS​
to the full Board of Directors. The Company continues to strengthen its cybersecurity infrastructure, staffing, and controls. Improving our resiliency against cybersecurity threats remains a key focus for our Board and management. Key actions include clarifying first-line roles, responsibilities, and accountability, increasing employee training, conducting annual cross-functional cyber tabletop exercises, engaging in a high-level board tabletop exercise, and enhancing internal reporting to the Board and its committees. This reporting includes results from regular systems vulnerability scans and other controls testing. The Information Security team, along with the Company’s internal auditors, periodically engages third parties to assess the maturity of the Company’s cybersecurity efforts and help manage associated risks. The Company also maintains cybersecurity insurance to mitigate the impact of potential breaches. To date, no breaches have occurred.

​ | ​ | BOARD OF DIRECTORS Our Board assumes a significant oversight role in risk management both through its actions as a whole and through its committees. Additional information concerning each of the following committees may be found in the “Corporate Governance — Board Committees” section of this Proxy Statement. | ​ | ​

​ | ​ | MANAGEMENT While each of these committees is responsible for evaluating certain risks and overseeing the management of these risks, the entire Board is regularly informed through committee reports and direct presentations by management about such risks. Select members of management attend our Board and Board committee meetings (other than executive sessions) and are available for questions regarding particular areas of risk. | ​ | ​

Corporate Responsibility
Our core beliefs define who we are as a company and how we interact with our employees, our communities, our shareholders and our environment. Our Corporate Responsibility Steering Committee, comprised of members of executive management as well as our Chief Corporate Responsibility Officer, oversees and guides the Company’s efforts, including establishing and implementing strategy and goals in various areas, such as inclusion, engagement, community investment and community service, to name just a few. We also have a cross-functional working group to establish metrics and gather information for additional initiatives. Our Board of Directors is actively engaged in our corporate responsibility efforts, with quarterly reviews by the Board’s Executive Compensation Committee of our commitment to

​ | 2025 Proxy Statement | Corporate Governance | ​ | ​ | 29 | ​

TABLE OF CONTENTS​​​
our employees, our Diversity and Inclusion Committee of our commitment to inclusion, and our Governance Committee of our commitment to our communities, customers and the environment.
Shareholder Engagement
The Board of Directors values the perspectives of our shareholders and solicits feedback from our largest shareholders annually. These meetings help us to understand our investors’ expectations and receive feedback on various topics, including executive compensation, governance and ESG initiatives. The meetings also provide an opportunity to discuss other topics the investors may be interested in. As part of our annual shareholder engagement program, the Company proactively reached out to holders of 66.5% of our common shares in the fall of 2024, including 27 of the largest shareholders of the Company. We held 4 meetings with shareholders representing approximately 24% of our shareholder base. Several shareholders declined meetings, indicating no current concerns related to the Company. Additionally, our executive leaders, including our CEO and Chief Financial Officer, regularly engage with current and prospective investors through earnings calls, participation in conferences and other channels. The results of the conversations were reported to the CGNC, the Compensation Committee and the full Board of Directors. Based on investor feedback we are including additional comparative disclosure in the Company’s Corporate Social Responsibility Report, and additional information in this Proxy Statement regarding our director nominee skills and qualifications.
Director Independence
Our Board has determined that all of our directors, except Archie M. Brown, our current Chief Executive Officer, are independent directors as that term is defined in the Nasdaq Rules. In addition, our Board has determined that each member of the Audit, Executive Compensation, and Corporate Governance and Nominating Committees is independent under such definition and that the members of the Audit Committee are independent under the additional, more stringent requirements of the Nasdaq Stock Market and the Exchange Act applicable to audit committee members. These determinations are made annually, most recently in March 2025.
Under the Nasdaq Rules and our Corporate Governance Principles, independent directors must not have a relationship with the Company that would interfere with the exercise of independent judgment in carrying out the responsibilities of being a director. In making this determination, our Board reviews and evaluates transactions and relationships with Board members to determine the independence of each of the members.
Board Leadership Structure
Our Board leadership structure includes a Chair of the Board (Claude E. Davis) and a Lead Independent Director (Vincent A. Berta). Because of Mr. Davis’s previous role as CEO and President of the Company, from which he retired in 2019, the Board believes it is important to continue to split the roles of Chair of the Board and Lead Independent Director and intends to continue to have an independent director in the role of Lead Independent Director. The Chair of the Board presides over each Board meeting and performs such other duties as may be incident to the office as determined by the Board. The Lead Independent Director has responsibility for consulting with the Chair regarding Board meetings

​ | 30 | ​ | ​ | 2025 Proxy Statement | Corporate Governance | ​

TABLE OF CONTENTS​
and meeting agendas, acting as a liaison between the Chair and the independent directors with respect to various matters, and leading executive sessions of the independent directors. Although our corporate documents would allow our chair to also hold the position of chief executive officer, our Corporate Governance Principles provide that these two positions must be separate. The Board believes that the existing structure with a Lead Independent Director has worked effectively, particularly with respect to the Lead Independent Director’s role as liaison between the Chair and the independent directors. The Chair, Mr. Davis, is best situated to serve as Chair of the Board because of his extensive experience in the banking industry and his history as former President and CEO of the Company, and the Company and the shareholders are well served by having his industry expertise, knowledge and visibility in the role. The Board intends to continue to evaluate the appropriate structure of the Board from time to time.
Board Assessments
The Governance Committee oversees our annual assessment process. The process consists of several parts, all of which are designed to ensure that the full board, each committee, and each individual director performs effectively and meets the requirements of our Governance Principles, fiduciary obligations and applicable charter documents. Additionally, the CGNC evaluates the skills and resources available on our board in connection with director recruitment and refreshment activities. All of our board and director assessments are done internally, although pursuant to our Governance Principles, the Board is required to use a third party to assist in the assessment every three to five years. In 2023, the CGNC retained an independent third party to conduct an assessment of the Board and each director. The third party attended a board meeting and interviewed board members and executive management both in-person and via questionnaires. The results of the assessment by the third party were delivered to the board in 2024.

​ | ​ | Full Board Assessment | ​ | ​ | ​ | The Board Questionnaire is reviewed and updated, including comparison to the Governance Principles and the Company charter documents, to ensure relevant information is collected. | ​ | ​ | ​ | The Questionnaire is completed by all members of the Board on an anonymous basis.

Evaluating Nominees and Electing Directors
Evaluating Nominees
The CGNC evaluates director candidates based upon criteria established by the committee and applies the same evaluation process to all director nominees regardless of whether the nominee is recommended by a shareholder or by the Board. The criteria evaluated by the CGNC may include, among other things, the candidate’s judgment, integrity, leadership ability, business experience, industry knowledge, public company experience, professional reputation, and ability to contribute to board member diversity (including, but not limited to gender, race, and ethnicity, as well as experience, geography, qualifications, attributes, and skills). The CGNC recognizes that diversity of the Board is an important part of its analysis as to whether the Board constitutes a body that possesses a variety of complementary skills and experiences. The CGNC also considers whether the candidate meets independence standards under the Nasdaq Rules and the rules promulgated by the SEC, is “financially literate” or a “financial expert” if appropriate for governance needs, is available to serve, and is not subject to any disqualifying factor. No single individual trait is given particular weight in the decision process.
Policy on Majority Voting
Although our Articles of Incorporation and Amended Regulations provide that director nominees who receive the greatest number of shareholder votes are automatically elected to the Board, our Board has adopted a policy on majority voting for the election of directors that is included in our Corporate Governance Principles. The majority voting policy requires nominees who receive a greater number of votes “withheld” from his or her election than votes “for” his or her election to tender his or her written resignation to the CGNC for consideration by the committee following the certification of the shareholder vote. This requirement applies only in an uncontested election of directors, which is an election in which the only nominees are persons nominated by the Board.
Upon its receipt of a resignation from a director who has not received the requisite shareholder vote, the CGNC will then consider the resignation and make a recommendation to the Board concerning whether to accept or reject such resignation. In making its recommendation to the Board, the CGNC will consider all factors deemed relevant by members of the committee, including the stated reason or reasons why shareholders who cast “withhold” votes for the director did so, the qualifications of the director (including, for example, whether the director serves on the Audit Committee of the Board as an “audit committee financial expert” and whether there are one or more other directors qualified, eligible,

​ | 32 | ​ | ​ | 2025 Proxy Statement | Corporate Governance | ​

TABLE OF CONTENTS​​​
and available to serve on such committee in such capacity), and whether the director’s resignation from the Board would be in the best interest of First Financial and its shareholders.
The CGNC also will consider a range of possible alternatives concerning the director’s tendered resignation, including acceptance of the resignation, rejection of the resignation, or rejection of the resignation coupled with a commitment to seek to address and cure the underlying reasons reasonably believed by the committee to have substantially resulted in the “withheld” votes. The Board will take formal action on the CGNC’s recommendation no later than 90 days following the certification of the shareholder vote. In considering the committee’s recommendation, the Board will consider the information, factors and alternatives raised by the committee and such additional information, factors and alternatives as the Board deems relevant. We will publicly disclose, in a Form 8-K filed in a timely manner with the SEC, the Board’s decision, together with an explanation of the process by which the Board made its decision and, if applicable, the Board’s reason or reasons for rejecting the tendered resignation within four business days after the Board makes its decision.
Shareholder Nominations for Election to the Board
The CGNC will consider director candidates recommended by shareholders in accordance with the procedures outlined in the Amended Regulations. In order to be recommended for a position on the Board by the committee, a proposed nominee must, at a minimum, (i) be able to comply with the Company’s Corporate Governance Principles, and (ii) through a combination of experience and education, have the skills necessary to make an effective contribution to the Board. In connection with next year’s Annual Meeting of Shareholders, the CGNC will consider director nominees recommended by shareholders provided that notice of a proposed nomination is received by the Company no later than February 27, 2026, as provided in the Amended Regulations. Notice of a proposed nomination must include the information outlined in the Amended Regulations and should be sent to First Financial Bancorp., Attention: Karen B. Woods, Corporate Secretary, 255 E. Fifth Street, Suite 2900, Cincinnati, OH 45202.
Director Education
We recognize the importance of our directors keeping current on Company and industry issues and their responsibilities as directors. All new directors attend orientation training soon after being elected to the Board. The Board also encourages attendance at continuing education programs for Board members, which may include internal strategy or topical meetings, third-party presentations, and externally offered programs.
Share Ownership Guidelines
The Company maintains a share ownership requirement for its non-employee directors equal to five times the director’s annual cash retainer. If a director is not in compliance with the share ownership requirement, he or she is required to hold 75% of the net after tax shares received by the director as part of the annual retainer until the share ownership requirement is met.
All directors are currently in compliance with the share ownership requirements.
In calculating directors’ share ownership, the Company includes shares owned individually and unvested restricted shares.
We have also implemented stock ownership and retention guidelines for our named executive officers described further in the Executive Compensation portion of this Proxy Statement.
Succession Planning
In light of the critical importance of executive leadership to our success, we have instituted an annual succession planning process which is guided by the CGNC.

​ | ​ | The CGNC reports to the full Board on its findings and the Board deliberates in executive session on the CEO succession plan. | ​ | ​

Meetings of the Board of Directors and Committees of the Board
During 2024, the Board held ten scheduled meetings. We believe it is important for our directors to participate in board and committee meetings. A director who participates in fewer than 75% of scheduled meetings of the Board and committees of which the director is a member, or who does not attend the annual meeting of shareholders, unless excused by the Board, is subject to not being re-nominated to the Board. In 2024, all directors attended more than 75% of the scheduled meetings and all directors except Vincent Berta and Thomas O’Brien, who were excused, attended the 2024 Annual Meeting of Shareholders.
The Board also held seven executive sessions in 2024 where only independent directors were present.
Board Committees
Through March 28, 2025, our Board had established the following standing committees: Audit Committee, Capital Markets Committee, Executive Compensation Committee, Corporate Governance and Nominating Committee, Diversity and Inclusion Committee, and Enterprise Risk and Compliance Committee. Each committee operates pursuant to a committee charter that is approved by the Board, which is the case for the CGNC Charter, or by the CGNC to whom the Board has delegated the authority to approve other committee charters. Each Board committee serves as a joint board committee of First Financial Bank in addition to being a Board committee of First Financial Bancorp.
The charters of the Audit, Compensation, Corporate Governance and Nominating and Enterprise Risk and Compliance Committees each comply with current Nasdaq Rules regulating charters and corporate governance. Each of these charters contain additional information regarding the responsibilities, structure, and purpose of the committees and are available under the Corporate Governance portion of our investor relations website (www.bankatfirst.com/investor-relations.html).

Review and Approval of Related Person Transactions
Each year, our directors and executive officers complete annual questionnaires designed to elicit information about potential related person transactions and transactions that may otherwise affect the independence of a director. The responses to these questionnaires are reviewed by the General Counsel and Corporate Secretary of the Company, and outside counsel if appropriate, to determine if there are related person transactions. Pursuant to the Governance Principles of the Board of Directors, any potential related person transaction (regardless of dollar amount) is required to be submitted to the Audit Committee of the Board for approval at a meeting of the Audit Committee and would also be considered by the CGNC when making independence determinations. The determinations of each Committee are documented in the minutes of its meetings.
Pursuant to the Corporate Governance Principles, no director shall perform professional services for the Company or its affiliates in a manner that interferes with that director’s independence under the Nasdaq Rules. This prohibition applies to services provided (1) directly by the director (or an immediate family member) or (2) where the director (or an immediate family member) is affiliated with the organization that provides professional services to the Company. This prohibition does not apply to professional services that are provided by the director to clients of the Company (or its affiliates) where the Company (or its affiliates) has not given instruction that the service be provided by the director and the Company (or its affiliates) is not the party responsible for payment for the professional services. Professional services can be characterized as advisory in nature, generally involve access to sensitive company information or to strategic decision-making, and typically have a commission- or fee-based payment structure. Professional services may include services such as investment services, insurance services, accounting/auditing services, consulting services, marketing services, legal services, property management services, realtor services, lobbying services, executive search services, and IT consulting services.
First Financial has, and expects to have in the future, banking relationships in the ordinary course of business with directors, executive officers, principal shareholders, and their affiliates on the same terms, including interest rates and collateral on loans, as those prevailing at the same time for comparable transactions with others. Normal, arms-length banking relationships entered into in the ordinary course of business, and consistent with applicable federal banking regulations, are not considered to interfere with a director’s independence. Service specialization, rate concessions, fee concessions, or other service or product modifications may similarly be offered to directors and executive officers, and their affiliates, if the same would be offered to other similarly situated clients on a non-discriminatory basis in the ordinary course of business. All loans or extensions of credit to a director or officer, or their affiliates, (i) were made in compliance with Federal Reserve Board Regulation O, (ii) were made in the ordinary course of business, (iii) were made on substantially the same terms, including interest rates and nature of collateral, as those prevailing at the time for comparable transactions with other persons not related to the Company, and (iv) did not involve more than the normal risk of collectability or present other unfavorable features. In addition, the Company or its subsidiaries from time to time may pay immaterial amounts for such items as event sponsorships and contributions to not-for-profit entities with which our directors have relationships and which payments are in furtherance of our Company’s business interests.
Transactions with Related Parties
Except as described below, during 2024, no related person transactions involving our directors or executive officers (or members of their immediate family) requiring disclosure in this Proxy Statement were identified nor are any such related person transactions currently proposed.

​ | 2025 Proxy Statement | Corporate Governance | ​ | ​ | 37 | ​

TABLE OF CONTENTS​​
In the fourth quarter of 2023, the Company began exploring investment products related to its BOLI portfolio. One of the investment partners consulted was Fort Washington Investment Advisors, Inc. of which Board member Maribeth Rahe is the President and Chief Executive Officer. Although she was not personally involved in any discussions, because the value to be paid to Fort Washington as part of the transaction was in excess of  $120,000, in an abundance of caution, Ms. Rahe voluntarily removed herself from the Audit Committee on January 1, 2024.
The Company ultimately chose Fort Washington as the investment partner and the Board engaged in the required process to consider and approve the related person transactions, as described below. Following approval, the BOLI transaction was completed on February 8, 2024.
As required by the Company’s Governance Principles, the Audit Committee approved the related party transaction at its January 2024 meeting. Also in January 2024, the CGNC considered the transaction and the effect, if any, on Ms. Rahe’s ability to exercise independent judgment on the Board. The CGNC determined that Ms. Rahe remained an independent director, although was disqualified from any future service on the Audit Committee of the Board.
Compensation Committee Interlocks and Insider Participation
During 2024, no member of the Compensation Committee was an employee, officer or former officer of the Company. None of our executive officers served in 2024 on the board of directors or Compensation Committee (or other committee serving an equivalent function) of any entity that had an executive officer serving as a member of our Board or the Compensation Committee. All banking or financial services transactions between the Compensation Committee members and First Financial Bank were entered into in the ordinary course of business. No other relationships required to be reported under the rules promulgated by the SEC exist with respect to members of the Company’s Compensation Committee.
Insider Trading Policy/Policy Against Hedging and Pledging Activities
Our Board has adopted an Insider Trading Policy that governs the purchase, sale or other distribution of Company securities owned by our directors, officers, associates and other covered persons. Additionally, our Insider Trading Policy prohibits our directors, officers and associates from (1) engaging in any transactions, other than transactions that are specifically excluded under the Insider Trading Policy, while in the possession of material nonpublic information; (2) recommending or giving an express opinion on the purchase or sale of Company securities while in possession of material nonpublic information; (3) disclosing material nonpublic information whatsoever to persons within the Company whose jobs do not require them to have that information, or outside the Company to other persons, including, but not limited to, family, friends, business associates, investors, analysts and consulting firms, unless such disclosure has been authorized by the Company or is required in the performance of a person’s job duties for the Company; (4) assisting anyone in engaging in activities prohibited by the Insider Trading Policy while in possession of material nonpublic information; (5) hedging transactions with respect to First Financial shares, including prepaid variable forward contracts, equity swaps, collars and exchange funds, and trading in any derivative security relating to First Financial shares, and (6) pledging First Financial shares as collateral for a loan or holding such shares in a margin account. The Company also follows procedures for the repurchase of its securities. We believe our Insider Trading Policy and repurchase procedures are designed to promote compliance with insider trading laws, rules and regulations. Each year all associates are asked to affirmatively acknowledge their obligation to follow the Insider Trading Policy. To review our Insider Trading Policy, see Exhibit 19  —  Insider Trading Policy filed with the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.
Executive Officers
Disclosure regarding the executive officers of the Company is set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC under the heading “Information About Our Executive Officers,” which is incorporated into this Proxy Statement by reference.

Introduction and Named Executive Officers
This Compensation Discussion and Analysis (this “CD&A”) describes and explains the material elements of 2024 compensation for our Chief Executive Officer, our Chief Financial Officer, and our other highly compensated executive officers. Detailed information regarding the compensation of these executive officers, also called “Named Executive Officers” or “NEOs,” is set forth in the tables following this CD&A. We also provide an overview of our executive compensation philosophy and our executive compensation program. In addition, we explain how and why the Compensation Committee arrived at specific compensation policies and decisions involving the NEOs.
For 2024, our Named Executive Officers are:

Name | ​ | ​ | Title | ​
Archie M. Brown | ​ | ​ | President and Chief Executive Officer | ​
James M. Anderson | ​ | ​ | Chief Financial Officer and Chief Operating Officer | ​
Richard S. Dennen | ​ | ​ | Chief Corporate Banking Officer | ​
Karen B. Woods | ​ | ​ | General Counsel and Chief Administrative Officer | ​
Amanda M. Neeley | ​ | ​ | Chief Consumer Banking and Strategy Officer | ​

Best Practices
Our Compensation Committee follows many compensation and corporate governance best practices when establishing executive compensation:

​ | What We Do | ​ | ​ | What We Don’t Do | ​
​ | ✓ Mandate that all members of the Compensation Committee must be independent ​ | ​ | ​ | X Include tax gross-ups in our compensation plans ​ | ​
​ | ✓ Impose robust stock ownership guidelines on our executive officers ​ | ​ | ​ | X Provide our executives with significant perquisites ​ | ​
​ | ✓ Emphasize long-term compensation for executives, including a three-year vesting period on all long-term incentive awards ​ | ​ | ​ | X Pay dividends on unvested restricted stock. All dividends accrue and are paid only on earned shares once the restricted stock has vested ​ | ​
​ | ✓ Regularly obtain guidance from an independent compensation consultant as to the amount and design of compensation ​ | ​ | ​ | X Allow our directors, executives or other employees to hedge, pledge or sell short our stock ​ | ​
​ | ✓ Require a double trigger in the event of a change in control (both a change in control and an involuntary termination or reduction in compensation must occur) before severance awards may be paid ​ | ​ | ​ | X Allow shares forfeited under our equity plans to be re-issued (share recycling) ​ | ​
​ | ✓ Require a double trigger for the acceleration of vesting of our equity awards in the event of a change in control ​ | ​ | ​ | X Allow for the repricing of any stock options ​ | ​
​ | ✓ Provide for clawbacks of incentive compensation in the event of a restatement of our financial statements as well as willful misconduct or gross negligence ​ | ​ | ​ | ​ | ​
​ | ✓ Permit discretion by the Compensation Committee to adjust compensation for various qualitative and quantitative factors, including its assessment of the quality of risk management ​ | ​ | ​ | ​ | ​
​ | ✓ Consider the Company’s “say-on-pay” vote results when making compensation decisions ​ | ​ | ​ | ​ | ​
​ | ✓ Align pay for performance ​ | ​ | ​ | ​ | ​
​ | ✓ Structure a majority of NEO compensation to be at risk ​ | ​ | ​ | ​ | ​
​ | ✓ Link the payment of incentives to achievement of key strategic business objectives that drive shareholder value ​ | ​ | ​ | ​ | ​
​ | ✓ Pay a significant percentage of total compensation in the form of equity compensation to align the interests of our NEOs with those of our shareholders ​ | ​ | ​ | ​ | ​
​ | ✓ Cap incentive payouts at 2x target ​ | ​ | ​ | ​ | ​

TABLE OF CONTENTS​​​

​ |  | ​ | ​ | Compensation Philosophy and Objectives | ​

The compensation program adopted by the Compensation Committee is designed to reward employee performance and the growth of long-term shareholder value. The Compensation Committee seeks to attract, retain and motivate the Company’s employees, including our NEOs, by aligning competitive, market-based compensation programs with the Company’s objectives, business strategy and financial performance. At the same time, the Compensation Committee seeks to ensure that the Company’s compensation program promotes a customer-focused culture in which employees are not incentivized to take inappropriate risks.
The Compensation Committee has identified the following guiding principles that form the basis for the Company’s compensation program. Compensation should:

​ | ​ | ▪ Support a pay-for-performance culture that results in the growth of long-term shareholder value. ​ ▪ For executives, a higher percentage of pay should be variable based on the achievement of corporate financial goals. The compensation program should also promote stock ownership to enhance alignment with shareholders. ​ ▪ For non-executives, compensation should motivate both corporate and individual goals. ​ | ​ | ​

​ | ​ | ▪ Drive alignment with the Company’s strategic plan and business goals, creating a clear line of sight between objectives and the rewards for achieving them. ​ | ​ | ​

​ | ​ | ▪ Be competitive within the market to enable the Company to attract and retain high performing employees who are critical to the Company’s success. ​ | ​ | ​

​ | ​ | ▪ Incorporate proper governance practices and be structured to ensure employees are not incentivized to take unnecessary or excessive risks. ​ | ​ | ​

​ | ​ | ▪ Be fair, internally equitable and flexible when appropriate and necessary. ​ | ​ | ​

​ |  | ​ | ​ | Compensation Decision-Making | ​

Three parties play an important role in establishing compensation levels for the Company’s executive officers: (i) the Compensation Committee, (ii) senior management, and (iii) outside advisors. The sections that follow describe the role each of these parties plays in the compensation-setting process, as well as other important factors that impact compensation decisions.
Role of the Compensation Committee
The Compensation Committee has the responsibility to:
▪
Review and approve the composition of the peer group companies used to assess the Company’s pay practices, target pay opportunities, and establish performance goals and objectives;
​
▪
Approve the executive compensation plan design and target structure, including setting targets for incentives using management’s internal business plan, industry and market conditions and other factors;
​
▪
Review the performance and determine the compensation of the CEO and other executive officers;
​
▪
Determine the amount of, and approve, each element of total compensation paid to the NEOs, and determine the general elements of total compensation for other senior officers;
​

​ | 2025 Proxy Statement | Executive Compensation | ​ | ​ | 43 | ​

TABLE OF CONTENTS​​​
▪
Review all quantitative and qualitative components of compensation (both target and actual) for the CEO and the other NEOs, including base salary, bonus, and long-term incentives;
​
▪
Maintain an independent and effective Compensation Committee that promotes independent oversight of executive pay programs with appropriate skills, knowledge, experience, and sound processes for compensation decision-making; and
​
▪
Define potential payments to executive officers under various termination events, including retirement, termination for cause and not for cause, and upon a change in control.
​
In determining the amount of NEO compensation each year, the Compensation Committee reviews competitive market data from our compensation peer group as well as the broader banking industry. It makes specific compensation decisions and awards based on such information, along with Company performance, individual performance and other circumstances as appropriate.
Role of Executive Management in Compensation Decisions for NEOs
Throughout the year, the Compensation Committee meets with the CEO and other executive officers to solicit and obtain recommendations with respect to the Company’s compensation programs and practices. The CEO makes recommendations to the Compensation Committee as to the appropriate base salaries, annual cash incentive opportunities, and stock awards for the executive officers other than himself.
In approving compensation for 2024, the Compensation Committee considered the CEO’s recommendations for the executive officers. The Compensation Committee, in consultation with its compensation consultant, the Chair of the Board and the Lead Director, made its own determinations regarding the compensation for the CEO, which were then ratified and approved by the Board.
Role of the Compensation Consultant
To assist in its efforts to meet the objectives outlined above in 2024, the Compensation Committee retained Meridian Compensation Partners, LLC (“Meridian”) to provide general executive compensation consulting services to the Compensation Committee and to the Company. Pursuant to the Compensation Committee’s charter, the Compensation Committee has the power to retain or terminate such consultant and engage other advisors. A representative of Meridian regularly participated in meetings of the Compensation Committee, including executive sessions without management present.
Meridian typically collaborates with management to obtain data, clarify information, and review preliminary recommendations prior to the time they are shared with the Compensation Committee. The consultant provides data regarding market practices and works with management to develop recommendations for changes to plan designs and policies consistent with the philosophies and objectives discussed earlier. In accordance with SEC Rules and the Nasdaq Rules, the Compensation Committee took appropriate actions to confirm the independence of Meridian, and to determine that the services provided by Meridian do not give rise to any conflicts of interest.
Market Competitiveness
The Compensation Committee considers the compensation practices of a group of similarly sized publicly traded financial services/banking organizations designated as the Company’s peer group in establishing and reviewing the Company’s performance, the structure of the Company’s compensation program, and the actual compensation of our executive officers. The Compensation Committee selected companies to be included in the peer group based on their asset size (approximately one-half to two times the asset size of the Company), business model, products, services and geographic location as compared to that of the Company. The Compensation Committee reviews and approves the peer group annually with input from our independent compensation consultant and management.
In 2024, the Compensation Committee reviewed the institutions comprising the 2023 peer group and removed two banks (Heartland Financial USA, Inc. and S&T Bancorp, Inc.) due to being acquired or changes in asset size. The Compensation Committee added two banks (Home Bancshares, Inc. and WSFS Financial Corporation) to the peer group for 2024, each of which met the foregoing selection criteria.

Our Compensation Committee uses peer information as a reference point when evaluating the elements and amounts of the compensation paid to our Chief Executive Officer and our other executive officers. However, the Compensation Committee does not set compensation of our executive officers at a specific benchmark level (e.g., median of peer group). Peer group data is one of several factors used by the Compensation Committee when setting the compensation of our Chief Executive Officer and other executive officers.

​ |  | ​ | ​ | Compensation of Executives in 2024 | ​

The Compensation Committee regularly reviews peer and industry information concerning levels of compensation and performance in order to make competitive pay decisions. In 2024, the Compensation Committee used this information and analysis as a reference for setting pay opportunities, such as changes to base salary, annual incentive awards and long-term incentive grants.
Elements and Mix of Compensation
The three primary components of executive compensation are base salary, annual incentive awards and equity based long-term incentive awards. Benefits comprise a smaller component of overall pay. The purpose and features of each component are summarized in the sections below.

​ | Primary Elements of Compensation | ​ | ​ | Base Salary | ​ | ​ |  | ​ | ​ | To competitively compensate executives for day-to-day contributions, skills, experience, and expertise. | ​
​ | Short-Term Incentive Compensation | ​ | ​ |  | ​ | ​ | To motivate executives through the opportunity to share in the rewards of the current year’s results. | ​
​ | Long-Term Equity Incentive Compensation | ​ | ​ |  | ​ | ​ | To motivate executives through the opportunity to share in the rewards of sustained long-term results and value creation consisting of both time- and performance-based restricted stock. | ​
​ | Additional Benefits | ​ | ​ | Employment Agreements and Change in Control and Severance Agreements Retirement and other benefits Limited perquisites and other personal benefits. | ​ | ​ |  | ​ | ​ | To provide competitive benefits that encourage retention by supporting the security and protection of executives and their families | ​

The Compensation Committee takes a holistic approach to establishing the total compensation package for executives and each element of compensation is interdependent on the other elements. Applying the Company’s core values and drawing upon the principles and philosophy discussed above, the Compensation Committee utilizes these elements of compensation as building blocks to construct a complete compensation package for each executive that appropriately satisfies the core design criteria of pay for performance, alignment with shareholder interests, market competitiveness, proper governance and compliance with all legal and regulatory guidelines.
The mix and relative weighting of each compensation element reflect the competitive market and the Company’s compensation philosophy. The mix of pay may be adjusted from time to time to best support our immediate or longer-term objectives, changes in executive responsibility, and internal consistency.
Target compensation for each NEO is a mix of short-term (cash) and long-term (stock) incentives. A substantial portion of this mix is at risk and varies based on the performance of the Company, including the creation of long-term shareholder value. The emphasis on compensation elements related to performance is specifically intended to affect the actual level of compensation realized versus target. If the Company performs well (based on both internal objectives and peer group comparisons), award levels are intended to be strong. If the Company underperforms, award levels and values will be negatively impacted.

TABLE OF CONTENTS
The mix of compensation awarded in 2024 to our NEOs reflects our compensation philosophy. A substantial portion of our executives’ compensation is at risk and tied to performance goals that align with the Company’s strategy and shareholder experience, with a heavier weighting on long-term equity compensation than the short-term cash incentive.
CEO Target Pay Mix
Other NEOs Average Target Pay Mix
Base Salary
Base salaries for our NEOs reflect their role and value to the Company. Base salaries are reviewed annually and adjusted as appropriate to reflect each NEO’s performance, contribution, and experience as well as relative position to the market and each other. Base salary levels are a foundational component of compensation since several elements of compensation are linked to this core element (e.g., cash and stock incentives). The Compensation Committee reviews base salaries annually but may engage in additional reviews as necessary to address market competitive increases or to reflect increases in a particular NEO’s scope and responsibilities.
During 2024, based on market conditions and in particular the continued focus on liquidity, the Company capped base salary increases for all executive and senior management at 2%. The Compensation Committee reviewed executive base salaries and approved increases to executive pay based on the considerations noted above, and in particular the internal limitations established for the year. Based on these considerations, the Compensation Committee approved the following changes to executive base compensation:

​ | Named Executive Officer | ​ | ​ | 2023 Base Salary | ​ | ​ | Percentage Increase | ​ | ​ | 2024 Base Salary | ​
​ | Archie M. Brown | ​ | ​ | ​ | ​ | $850,000 | ​ | ​ | ​ | ​ | ​ | 2% | ​ | ​ | ​ | ​ | ​ | $867,000 | ​ | ​

TABLE OF CONTENTS​
Short-Term Incentive Compensation
Short-term incentives serve as a key mechanism to vary pay levels according to Company-wide short-term performance, linking executive financial rewards to the value delivered to our shareholders. Such incentives are earned and paid annually, but only after established threshold corporate performance levels are achieved. To underscore the importance of creating value for our shareholders, payouts for the Company’s executive officers under the Company’s Short-Term Incentive Plan (“STIP”) focus on corporate, rather than individual, performance. This approach also emphasizes that collective individual performances will result in improved business performance and favorably impact shareholder value.
2024 Target Compensation. Generally, the Compensation Committee establishes target compensation levels for our executives under the STIP at the beginning of each fiscal year, taking into consideration such factors as peer compensation data, the Company’s compensation philosophy, program objectives, relevant market data, individual performance and the scope and responsibility of each individual. In general, target short-term incentive opportunities are targeted to be within 15% of market median levels, with executives having the opportunity to earn higher payouts if warranted based on the overall performance of the Company. The Company also considers the importance of increasing the percentage of executive pay that is performance-based rather than fixed, to better align executive pay with individual and Company performance.
In 2024, the Compensation Committee reviewed the executive team’s STIP target levels and, based on this review, determined that each NEO’s STIP target level should remain unchanged from 2023, except for Mr. Anderson’s STIP target level which was increased five percentage points, consistent with the considerations noted above as well as his additional responsibilities as Chief Operating Officer.
Target award opportunities are expressed as a percentage of actual base salary paid during the performance year. Actual awards may range from 0% to a maximum of 200% of the target award opportunity depending upon the level of achieved performance. The NEO target levels were as follows for the 2023 and 2024 plan years:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | Target STIP (as a percentage of base salary) | ​
​ | Named Executive Officer | ​ | ​ | 2023 | ​ | ​ | 2024 | ​
​ | Archie M. Brown | ​ | ​ | ​ | ​ | 90% | ​ | ​ | ​ | ​ | ​ | 90% | ​ | ​
​ | James M. Anderson | ​ | ​ | ​ | ​ | 70% | ​ | ​ | ​ | ​ | ​ | 75% | ​ | ​
​ | Richard Dennen | ​ | ​ | ​ | ​ | 70% | ​ | ​ | ​ | ​ | ​ | 70% | ​ | ​
​ | Karen B. Woods | ​ | ​ | ​ | ​ | 70% | ​ | ​ | ​ | ​ | ​ | 70% | ​ | ​
​ | Amanda M. Neeley | ​ | ​ | ​ | ​ | 60% | ​ | ​ | ​ | ​ | ​ | 60% | ​ | ​

2024 STIP Performance Measures
The Compensation Committee selected the 2024 STIP performance measures and their relative weightings based on their relevance as key, balanced measures that drive shareholder value creation and align with the Company’s internal, board-approved business plan. Performance is measured over a 12-month period that aligns with the Company’s fiscal year for all participants (including the NEOs).
When establishing the STIP measures for 2024, the Compensation Committee considered the Company’s internal priorities, peer practices and macroeconomic conditions. The Compensation Committee also considered its desire for plan stability over time in order to maintain effectiveness of the plan as a driver of performance.
The Compensation Committee approved for the 2024 STIP the same performance measures used in the 2023 STIP: (i) return on assets, (ii) classified assets and (iii) earnings per share growth. Consistent with 2023 STIP, each of the 2024 performance measures were evaluated relative to the KBW Index to determine pay outcome. Relative measures were chosen due to the income volatility in the banking industry, most recently due to the Federal Reserve’s limited interest rate cuts and the challenges of comparing results to a budget established months earlier that can become outdated due to major events, such as the COVID-19 pandemic or unanticipated interest rate changes.

TABLE OF CONTENTS
The following table summarizes the 2024 performance measures and weightings selected by the Compensation Committee:

Measure | ​ | ​ | Relative to: | ​ | ​ | Weighting | ​ | ​ | Rationale | ​
Return on Assets | ​ | ​ | KBW Index | ​ | ​ | ​ | ​ | 40% | ​ | ​ | ​ | The Compensation Committee believes that relative ROA has a strong correlation to shareholder value creation and provides an incentive to Company executives to achieve top quartile performance among its peers. | ​
Classified Assets | ​ | ​ | KBW Index | ​ | ​ | ​ | ​ | 30% | ​ | ​ | ​ | The Compensation Committee believes that relative classified assets emphasizes the Company’s commitment to a quality loan portfolio, rather than just portfolio growth, which in turn enhances shareholder value and the long-term success of the Company. | ​
Earnings Per Share Growth | ​ | ​ | KBW Index | ​ | ​ | ​ | ​ | 30% | ​ | ​ | ​ | The Compensation Committee believes that relative EPS growth rewards executives for Company earnings performance controlled for factors that affect the entire banking industry, such as the effects of the COVID-19 pandemic or rapidly rising or falling interest rates. | ​

The Compensation Committee also has discretion to make a downward adjustment to STIP payouts in the event of a material risk management failure or a material error that results in financial restatement. Additionally, the Compensation Committee has discretion to adjust the formulaically calculated payout for performance in non-financial areas that may or may not directly affect the Company’s achievement of specific financial metrics for a particular year but are nevertheless important to the enhancement of shareholder value.
The KBW Regional Banking Index (KBW Index) is made up of approximately 50 regional banks located throughout the country that are generally within an asset and market capitalization range comparable to the Company. This comparator group is broader than the Company’s established benchmarking peer group which is used in the process of setting overall compensation levels.
The Compensation Committee established the following performance goals for the Company’s 2024 STIP:

​ | Amanda M. Neeley | ​ | ​ | ​ | ​ | $346,402 | ​ | ​

The Compensation Committee made no discretionary adjustments to the formulaic STIP payout.
Long-Term Incentive Compensation
The Company’s long-term incentive plan (“LTIP”) is designed for the Company’s senior leaders who have a direct and measurable impact on the long-term performance of the Company. The LTIP is a key component of the total compensation package and is intended to help attract, motivate and retain top professionals in the organization. Because the LTIP awards vest over a three-year period, the awards serve to align the interests of management with those of our shareholders, including the long-term success of the Company and increased shareholder value.
2024 LTIP Awards
Setting 2024 LTI target value. The Compensation Committee set each NEO’s 2024 LTI target value taking into consideration such factors as peer compensation data, the Company’s compensation philosophy, program objectives, relevant market data, and each individual scope and responsibility. The LTIP target value was allocated equally between grants of performance-based restricted stock and time-based restricted stock. The following chart discloses each NEO’s 2024 LTIP target value (as a percentage of base salary) and the number of shares granted under the 2024 awards:

TABLE OF CONTENTS
2024 Time-Based Restricted Stock Awards
The 2024 time-based restricted stock awards generally vest over three years, with a third of each award vesting on each anniversary date of the date of grant. Dividends paid on restricted stock are held in escrow and not paid until the restrictions lapse and the stock is fully vested.
Performance-Based Awards
The Compensation Committee bases payout of the Company’s long-term performance-based stock grants on the attainment of two equally weighted performance measures: (i) our 3-year total shareholder return relative to the KBW index and (ii) our 3-year average return on assets relative to the KBW Index. The following table summarizes the rationale behind the performance-based measures and weightings selected by the Compensation Committee:

Measure | ​ | ​ | Relative to: | ​ | ​ | Weighting | ​ | ​ | Rationale | ​
3-year Total Shareholder Return | ​ | ​ | KBW Index | ​ | ​ | ​ | ​ | 50% | ​ | ​ | ​ | The Compensation Committee believes that total shareholder return, over a three year period, aligns the Company executives with the shareholders by matching executive compensation to the Company’s long term value to the shareholders. | ​
3-year average Return on Assets | ​ | ​ | KBW Index | ​ | ​ | ​ | ​ | 50% | ​ | ​ | ​ | The Compensation Committee believes that relative ROA has a strong correlation to shareholder value creation and provides an incentive to Company executives to achieve top quartile performance among its peers. | ​

2024 Performance-Based Restricted Stock Awards. The 2024 performance-based restricted stock grants vest at the conclusion of the three-year performance period ending on December 31, 2026. The award is structured such that at the end of the three-year performance period:
▪
For each metric, no portion of the award may vest if performance against the KBW Index is below the 25th percentile.
​
▪
50% of the award will vest if performance is at the 25th percentile.
​
▪
Above median performance (60th percentile) must be achieved for 100% of the award to vest.
​
▪
The maximum payout is capped at 150% of the initial award amount for performance at or above the 75th percentile.
​
▪
The number of shares that will vest is interpolated between the levels described above for performance between the 25th and 75th percentiles.
​
Vesting of 2022 LTIP Performance-Based Stock Awards
On March 5, 2025, the Compensation Committee approved the payout of certain awards of performance-based restricted stock issued on March 1, 2022, with a performance period ending on December 31, 2024. The performance-based restricted stock vested on March 5, 2025, upon the attainment of the following performance targets, each of which made up 50% of the metric:
▪
Return on Assets compared to banks in the KBW Index over the 36 months ended December 31, 2024; and
​
▪
Total Shareholder Return compared to banks in the KBW Index over the 36 months ended December 31, 2024.
​
The peer performance was calculated using the KBW Index based on the same performance scale outlined above. Both our Return on Assets and Total Shareholder Return were in the top quartile of the KBW Index for the 3-year period, resulting in a maximum payout of the awards. The calculation of the payouts in 2025 for all participants, including the Named Executive Officers of the Company, was as follows:

​ | ​ | ​ | ​ | KBW Index Results | ​ | ​ | FFBC Results | ​ | ​ | FFBC Percentile Ranking | ​ | ​ | Payout | ​

TABLE OF CONTENTS​
Executive Benefits
In addition to the three key elements noted above, the Company provides its executives with certain other benefits, as follows:
Employment, Severance and Change in Control Agreements
The Company has entered into an Employment and Non-Competition Agreement with Mr. Brown, and Severance and Change in Control Agreements with its other NEOs. The purpose of the agreements is to secure the continued service and dedication of the executives and to provide for certainty and fairness in the event an executive’s employment is terminated without cause or in the event of an actual or threatened change in control of the company.
The Company believes the agreements are important in the Company’s ability to attract and retain executives, particularly in the event the Company is engaged in a transaction which could constitute a change in control.
The terms of the employment and severance agreements, as well as the potential payments to be made to each of the NEOs in the event of their termination either without cause or in connection with a change in control, are discussed beginning on page 65 of this Proxy Statement.
Pension and Other Deferred Compensation Plans
Pension Plan
The First Financial Bancorp. Associate Pension Plan and Trust (“Pension Plan”) is a tax-qualified pension plan covering eligible employees (including the NEOs) of the Company. See the Pension Benefits Table on page 63 for the material terms and conditions of the Pension Plan as applicable to the NEOs for 2024.
Supplemental Executive Retirement Plan
The Company maintains a supplemental executive retirement plan to supplement the retirement benefits provided under the Pension Plan for certain senior executive officers of the Company to make up for legal limits applicable to the benefits provided under the Pension Plan. The SERP is an unfunded, unsecured pension benefit plan for a select group of highly compensated employees. See the Pension Benefits Table on page 63 for the material terms and conditions of the SERP as they pertain to the NEOs for 2024.
Group Term Life Insurance
All the NEOs are eligible for the Company-paid group term-life insurance benefit that is available to all full-time associates in the amount of two times annual base salary up to $600,000.
Other Benefits
Executives can participate in group medical and life insurance programs and a 401(k) plan with a discretionary performance-based contribution by the Company, both of which are generally available to all our associates on a non-discriminatory basis. The benefits serve to protect executives and their families against financial risks associated with illness, disability, and death and provide financial security during retirement through a combination of personal savings and Company contributions, taking advantage of tax-deferral opportunities where permitted.

​ |  | ​ | ​ | Compensation of Executives in 2025 | ​

In March 2025, the Compensation Committee met to consider the executive compensation program for 2025. The Compensation Committee, in consultation with Meridian, reviewed the Company’s compensation philosophy, the overall structure of the compensation program, the targets and metrics to be used in 2025, peer data regarding the mix and structure of compensation for executives in each role and the compensation to be awarded to executives.
Based upon its review of peer data and consideration of Company and executive performance, the Compensation Committee authorized certain adjustments to executives’ base compensation and incentive compensation targets.
The Compensation Committee also determined to maintain the same structure and metrics as 2024 for the LTIP, and to adjust the metrics for the STIP in 2025 to replace the classified asset metric with Net Charge Offs as a Percentage of Average Loans Relative to Peers. The Compensation Committee believes the net charge off metric will better measure

TABLE OF CONTENTS​​​
the Bank’s credit quality and loan performance by focusing on loans that the Bank has written off, rather than loans showing signs of stress but that remain outstanding.
Beginning January 1, 2025, the STIP metrics are as follows:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | Payout1 | ​
Metric | ​ | ​ | Weight | ​ | ​ | <25% of Peers | ​ | ​ | 50% of Peers | ​ | ​ | 75% of Peers | ​ | ​ | >90% of Peers | ​

The Compensation Committee believes the focus on relative performance measures drives focus on outperforming without fluctuations caused by events occurring in the banking industry in general and in particular subsequent to the annual budgeting process.

​ |  | ​ | ​ | Policies, Guidelines and Other Practices | ​

Evaluation for Excessive Risk in Compensation Programs
The following outlines the method by which the Company reviews and evaluates compensation programs, policies and procedures to prevent unnecessary and excessive risks that could threaten the value of the Company:
▪
The Compensation Committee discusses annually the governance structure and management practices to effectively monitor and manage risks in compensation programs, policies and procedures;
​
▪
To further mitigate risk, the Compensation Committee has responsibility for the design and evaluation of all executive compensation programs, including broad-based Short-Term and Long-Term Incentive Plans; and
​
▪
The Compensation Committee has responsibility to review and ratify the Company’s non-executive incentive compensation plans. The Compensation Committee’s review of incentive compensation plans is supported by management processes aligned with the Guidance on Sound Incentive Compensation Policies adopted by banking regulators in 2010. Incorporated into the management processes is a review, including a risk evaluation, of the components of the Company’s incentive plans by human resources, finance, and risk management personnel.
​
The Compensation Committee concluded in 2024 that risks arising from our executive and broad-based incentive compensation programs are not reasonably likely to have a material adverse effect on the Company.
Clawbacks
In October 2023, the Compensation Committee approved a revised Policy Regarding Recoupment of Compensation, adopting policies incorporating new rules required under the Dodd-Frank Wall Street Reform and Consumer Protection Act and the Nasdaq listing standards. Under the revised policy, the Company will be required to recoup erronerously awarded incentive compensation paid to executive officers in the event of material noncompliance with any financial reporting requirement resulting in the Company being required to restate its financial statements filed with the U.S. Securities and Exchange Commission.
Additionally, the policy provides that the Company may also recoup or seek forfeiture of all or part of any incentive compensation paid to any associate in the event:
▪
An associate’s misconduct or negligence results in an accounting restatement.
​
▪
An incentive compensation award was paid based on materially inaccurate data resulting from an associate’s fraud, willful misconduct or gross negligence.
​
▪
The incentive compensation paid or to be paid to non-executive officers is related to willful misconduct or gross negligence that either has had, or could reasonably be expected to have, a significant adverse reputational or economic impact on the Company (regardless of financial restatement).
​
▪
The Company becomes subject to any statute, regulation or other government direction that, in the opinion of legal counsel, requires the return of the incentive compensation paid to an officer.
​

​ | 2025 Proxy Statement | Executive Compensation | ​ | ​ | 53 | ​

TABLE OF CONTENTS​​​
The policy applies to all incentive compensation (including cash and equity awards) paid or received during the three years prior to any event as described above.
To review our clawback policy, see Exhibit 97 — Policy Regarding Recoupment of Compensation filed with the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.
Share Ownership Requirements
The Company maintains a share ownership requirement for its CEO equal to five times base salary. The share ownership requirement for the other NEOs is two times base salary. If the CEO or executive is not in compliance with the share ownership requirement, he or she is required to hold 75% of the net after tax shares received by the executive from option exercises or restricted stock vesting until the share ownership requirement is met.
The CEO and each of the executives are currently in compliance with the share ownership requirements.
In calculating executives’ share ownership, the Company includes shares owned individually, unvested time-based restricted shares and shares held in the Company’s 401(k) Savings Plan or other non-qualified deferred compensation plan. Unvested performance-based restricted shares are not counted towards the share ownership requirements.
Use of Discretion and Other Factors in Pay Decisions
While the Compensation Committee generally exercises discretion on a limited basis, we believe that providing the ability for the Compensation Committee to do so in determining the various elements of compensation is an important feature of the Company’s compensation philosophy. Because the Company has always taken a long-term view, we provide for the Compensation Committee to exercise judgment and discretion rather than relying solely on formulaic results, and we do not reward executives for taking outsized risks that produce short-term results. Therefore, the Company believes it is important that the Compensation Committee have sufficient flexibility to respond to: (i) the Company’s unique circumstances; (ii) prevailing market trends; (iii) competition for executive level talent in the financial institutions industry; (iv) the rapidly evolving financial and regulatory environment in which the Company operates; (v) the Company’s use of cross-functioning of executive assignments and cross-training as a matter of executive development and succession planning; and (vi) risk management objectives. The Company also believes it is in the best interest of the Company and its shareholders that the Compensation Committee have sufficient discretion to recognize and reward extraordinary performance in non-financial areas that may or may not directly affect the Company’s achievement of specific financial metrics for a particular year but are nevertheless important to long-range growth and the enhancement of shareholder value.
Stock-Based Compensation — Procedures Regarding Timing and Pricing of Grants
Our policy is to make grants of equity-based compensation only at current market prices. Absent special circumstances, it is our policy to grant annual equity awards at the regularly scheduled March meeting of our Compensation Committee. However, we may make a small percentage of grants at other times throughout the year, generally once per quarter, in connection with exceptional circumstances, such as the hiring or promotion of a key employee, special retention circumstances, or merger and acquisition activity.
For 2024, we approved equity awards during the March meeting of the Compensation Committee. This date allowed time for performance reviews following the determination of corporate financial performance for the previous year. The Compensation Committee neither takes into account material nonpublic information (MNPI) when determining timing and terms of equity awards nor times the grant of equity awards in connection with the release of MNPI.
We seek to make grants when our financial results have already become public, and when there is little potential for abuse of material non-public information in connection with equity-based grants. We believe we minimize the influence of our disclosures of non-public information on the long-term incentives by selecting meeting dates well in advance which fall several days or weeks after we report our financial results, and by setting the initial vesting periods at least one year from the date of grant. We follow the same procedures regarding the timing of grants to our NEOs as we do for all other award recipients.

2024 Board Compensation
​
The goal of the non-employee director compensation package is to attract and retain qualified candidates to serve on the Board of Directors, and to align the interests of the Board with those of the shareholders of the Company. In setting compensation, the Board considers primarily the fees paid by the Company’s compensation peer group, which is the same peer group used by our Compensation Committee to evaluate executive compensation. Board members are compensated with a combination of cash and stock-based compensation.
Compensation Consultant
The Compensation Committee engaged Meridian Compensation Partners, LLC as its consultant to assist in evaluating the Company’s director compensation for 2024. Meridian reviewed the amount of the Board’s compensation as well as the breakdown between cash and equity compensation in comparison to the Company’s peers. The Compensation Committee considered Meridian’s analysis in establishing 2024 director compensation.
Board/Committee Fees
The annual retainer for non-employee directors of the Company did not change in 2024, remaining at $130,000, of which a total of  $60,000 was paid in cash and the remaining $70,000 was awarded in restricted stock on the date of the 2024 Annual Meeting of shareholders. The restricted stock has a one-year vesting period. Directors do not receive any fees for service on the board of directors of First Financial Bank.
In May 2024, the additional cash retainers paid to the Chair of the Board and the Lead Independent Director of the Board increased from $62,500 to $75,000 and from $25,000 to $30,000, respectively. The additional cash retainers paid to the chairs of the Enterprise Risk and Compliance and Audit committees increased from $15,000 to $20,000 while the additional cash retainer paid to the chairs of the remaining committees increased from $10,000 to $15,000. The additional retainers paid to the Chair of the Board, the Lead Director of the Board and committee chairs compensate these directors for the extensive time that is devoted to their roles, including meetings with management, auditors, attorneys and consultants, and preparing board and committee agendas, and were adjusted based upon a review of market information. Cash director fees are paid quarterly.
Election to Purchase Stock with Cash Retainer
Directors have the opportunity, pursuant to the 2019 Director Fee Stock Plan, to elect to use all or a portion of their board fees to purchase the Company’s common shares. Shares are issued pursuant to the 2020 Stock Plan. For those directors who make an annual election to participate in the 2019 Director Fee Stock Plan, shares are issued directly to directors quarterly in lieu of cash payments.

Awards represent shares of performance-based restricted stock issued under the LTIP that vest after three years upon the attainment of certain pre-determined performance measures (generally total shareholder return and return on assets in each case compared to peer). Depending on the performance level achieved, the maximum award that may be earned for these performance-based restricted shares is 150% of the initial shares awarded. Dividends paid on both time- and performance-based restricted shares are held in escrow until such shares vest. For additional information, see page 50 of the Compensation Discussion and Analysis.
​
3.
Awards represent restricted shares awarded on March 7, 2024 based upon a closing price of the Company’s common shares of $22.16 as of the date of the award. All restricted shares vest annually in equal installments over a three-year period. For additional information, see page 50 of the Compensation Discussion and Analysis.
​
4.
Amounts represent the aggregate grant-date fair value of stock awards, including performance shares and restricted stock, granted under the Company’s 2020 Stock Plan during 2024, calculated in accordance with ASC 718. See notes 2 and 3, above, for additional information regarding these awards. For the performance shares, the amounts have been calculated taking into consideration the probable outcome of the respective performance conditions as of the date of grant (target). Dividends accrued but not paid until the vesting of the awards of performance shares and restricted stock are not included in the amounts reflected in this column. Assumptions used in the calculation of these amounts are described in Note 21 to our audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2024.

TABLE OF CONTENTS
Pension Plan
The material terms and conditions of the Pension Plan as applicable to the NEOs for 2024 who are currently employees of the Company are as follows:
Eligibility — The Pension Plan covers employees of the Company who have attained age 18 and completed one hour of service.
Benefit Formula — The Pension Plan provides an accrual to a participant’s account for each year in which the participant works 1,000 hours. All eligible associates receive a pension benefit annual accrual of 5% of compensation. For this purpose, compensation means the participant’s total cash remuneration from the Company prior to contributions to a cafeteria plan or a 401(k) plan, including bonuses, overtime pay and other special cash remuneration. However, compensation cannot exceed the compensation limit of Section 401(a)(17) of the Internal Revenue Code of 1986, as amended (the “Code”).
Interest — In 2024 participant accounts were credited with a rate of return (10.74%) equal to Vanguard Institutional Index Fund Institutional Shares (VINIX) and Vanguard Total Bond Market Index Fund Institutional Shares (VBTIX) weighted 40% and 60%, respectively.
Vesting — A participant becomes immediately vested in this retirement benefit upon hire.
Distribution — A participant’s account may be distributed at the participant’s election at any time after the participant separates from service. However, generally, it must be distributed by April 1st of the calendar year following the date of termination or the date the participant attains age 70 1∕2, whichever is later. The participant may elect to receive their account in a lump sum or as an annuity with an actuarial value equivalent to the value of their account. Each of our NEOs is eligible to participate in the Pension Plan with respect to the account balance formula and is fully vested in their Pension Plan retirement benefit.
Traditional Pension Benefit Formula — Benefits accruing prior to January 1, 2008 are generally calculated based on benefit service and average monthly compensation as of December 31, 2007.
Executive Supplemental Retirement Plan
The Company maintains a supplemental executive retirement plan to supplement the retirement benefits provided under the Pension Plan for certain senior executive officers of the Company in order to make up for legal limits applicable to the benefits provided under the Pension Plan. The SERP is an unfunded, unsecured pension benefit plan for a select group of highly compensated employees. The material terms and conditions of the SERP as they pertain to the NEOs for 2024 are as follows:
Eligibility — The SERP benefit is generally provided to those highly compensated employees of the Company whose compensation exceeds the IRS limits imposed on the Pension Plan and who have been designated as eligible to participate in the plan by the Company. All NEOs participated in the SERP in 2024.
Benefit Formula — The SERP provides a benefit in excess of the IRS compensation and benefit limits imposed by Sections 401(a) (17) and 415 of the Code, respectively, with respect to the service benefit component of the Pension Plan and the account benefit component of the Pension Plan. The benefit under the SERP is calculated as the difference between (x) the lump sum or periodic benefit the executive would have received under the Pension Plan, but for the applicable IRS compensation limits under Section 415 and 401(a) (17) of the Code, and (y) the lump- sum or periodic benefit the executive is entitled to under the Pension Plan. Compensation and years of service under the SERP generally have the same meanings provided under the Pension Plan.
Vesting — Participants are vested in their SERP benefit to the same extent they are vested in their retirement benefit provided under the Pension Plan. However, the Company generally reserves the right to forfeit and/or reduce a participant’s benefit under the SERP.
Time and Form of Payment — Payment of benefits under the SERP generally commence upon the participant’s qualifying termination of employment. The benefit generally may be payable in an annuity or lump sum, as agreed to by the executive and the Company. Annual SERP allocations for all NEOs and other eligible executives are 5% of eligible earnings.

TABLE OF CONTENTS
Potential Post-Employment Payments
We have entered into an employment agreement with Mr. Brown and severance and change in control agreements with our other NEOs that will require the Company to provide severance payments in the event of a termination of employment (other than for cause) or a termination of employment or resignation in connection with a change in control of the Company. The summaries below are qualified in their entirety by reference to the agreements themselves, copies of which are available from the Company or from the Company’s public filings with the SEC.
Employment and Non-Competition Agreement — Mr. Brown
The Company has entered into an Employment and Non-Competition Agreement (the “Employment Agreement”) with Mr. Brown. The Employment Agreement provides generally as follows:
Term. Mr. Brown’s employment agreement had an initial term of three years, which ended on April 1, 2022, and automatically renews for additional one-year terms, unless either party gives the other notice of an intention not to renew at least 90 days prior to the end of the current term.
In the event of a change in control, Mr. Brown’s agreement automatically renews for a two-year term.
Compensation. The Employment Agreement provides for the payment of base salary and participation in the Company’s STIP and LTIP. The base salary and the target short-term and long-term incentive compensation are subject to adjustment annually by the Compensation Committee.
Severance Benefits. The Employment Agreement provides for the payment of severance benefits if, during the term of the Employment Agreement, the Company terminates the executive’s employment without “Cause” ​(as defined in the Employment Agreement and below) or the resignation by the executive with “Good Reason” ​(as defined in the Employment Agreement and below). Upon termination of employment by the Company without Cause (other than for disability or death) or by the executive for Good Reason, the executive is entitled to receive the following payments and benefits:
▪
earned and unpaid base salary through the date of termination;
​
▪
continued payment of base salary for 24 months;
​
▪
installments equal to the lesser of  (i) two and one-half times the executive’s target bonus amount under the STIP, and (ii) two times the average of the STIP bonuses earned during the three years prior to the termination;
​
▪
outplacement assistance at the Company’s expense (at a cost of up to 5% of base salary); and
​
▪
up to twelve months of the employer portion of COBRA premium payment contributions from the Company.
​
If the executive’s employment is terminated by reason of his death or long-term disability, by the Company for Cause or voluntarily by the executive other than for Good Reason, the Company’s obligations to the executive are limited to payment of any accrued and unpaid base salary through the date of termination and the payment of any other benefits that are required to be provided to the executive under the terms of a plan or program in which he is a participant.
For purposes of the Employment Agreement, the term “Good Reason” is defined as a termination of employment by the executive within ninety days of the initial existence of one of the conditions described below which occurs without his consent: (i) a material diminution in base salary; (ii) a material diminution in his authority, duties, or responsibilities as provided for in his employment agreement, or (iii) any other action or inaction that constitutes a material breach of the Employment Agreement by the Company. In order to terminate for Good Reason, the executive is required to provide notice to the Company of the existence of the applicable condition for termination within thirty days of the initial existence of the condition, upon the notice of which the Company will have sixty days during which it may remedy the condition and not be required to pay the severance amount. “Cause” is defined as a (i) felony indictment or guilty or nolo contendere plea relating to a felony; (ii) fraud or embezzlement; (iii) willful misfeasance or dishonesty; (iv) other action or criminal conduct which materially and adversely affects the business or financial condition of the Company; or (v) a performance failure that is not corrected within 15 days of written notice from the Board of Directors.
Section 280G. In the event that any of the payments or benefits provided under the Employment Agreement or otherwise would constitute an “excess parachute payment” as defined in Section 280G of the Code, the payments or benefits under such agreements will be reduced to the maximum level that would not result in an excise tax

Restrictive Covenants. Mr. Brown is prohibited from revealing confidential information of the Company and disparaging the Company. In addition, Mr. Brown is prohibited from (i) competing with the Company or its affiliated companies while employed by the Company and for a period of 18 months following separation of employment and (ii) soliciting clients or hiring employees of the Company or its affiliated companies while employed by the Company and for a period of two years following separation of employment.
Severance and Change in Control Agreements — Mr. Anderson, Mr. Dennen, Mrs. Woods, and Mrs. Neeley
As of December 31, 2024, the Company is a party to Severance and Change in Control Agreements with Mr. Anderson, Mr. Dennen, Mrs. Woods and Mrs. Neeley (the “CIC Agreements”). The CIC Agreements provide generally as follows:
Term. Each of the CIC Agreements has a one-year term and renews automatically for successive one-year terms until either party gives notice of an intention not to renew at least 90 days prior to the end of the current term. In the event of a Change in Control (as defined in the CIC Agreements and below), the term of the CIC Agreement will be the one-year period following the consummation of the Change in Control, without the possibility of non-renewal.
Compensation. Each of the CIC Agreements provides for the payment of base salary and participation in the Company’s STIP and LTIP. The base salary and the target short-term and long-term incentive compensation are subject to adjustment annually by the Compensation Committee.
Severance Benefits. Each of the CIC Agreements provide for the payment of severance benefits in the event the Company terminates his or her employment without “Cause” ​(as defined in the CIC Agreements and below) or the executive resigns his or her employment with “Good Reason” ​(as defined in the CIC Agreements and below) within 12 months following a Change in Control.
Under the terms of the CIC Agreements, upon termination of the executive by the Company without Cause (other than as a result of death or disability) and not in connection with a Change in Control, the executive will be entitled to receive the following payments and benefits:
▪
earned and unpaid base salary through the date of termination;
​
▪
continued payment of base salary for 24 months;
​
▪
if the executive is a “Covered Employee” under IRS rules, an amount equal to the lesser of  (i) two times the executive’s target bonus amount under the STIP, and (ii) two times the average of the STIP bonuses earned during the three years prior to the termination, and if the executive is not a “Covered Employee”, two times his target bonus amount under the STIP;
​
▪
outplacement assistance at the Company’s expense (at a cost of up to 5% of the executive’s base salary); and
​
▪
up to twelve months of the employer portion of COBRA premium payment contributions from the Company.
​
If the termination of the executive is in connection with a Change in Control, the executive will be entitled to receive the following payments and benefits:
▪
earned and unpaid base salary and vacation pay through the date of termination;
​
▪
continued payment of base salary for 24 months;
​
▪
an amount equal to two times his or her target amount under the STIP;
​
▪
outplacement assistance at the Company’s expense (at a cost of up to 5% of the executive’s base salary); and
​
▪
up to twelve months of the employer portion of COBRA premium payment contributions from the Company.
​
As used in the CIC Agreements, “Change in Control” has the meaning given such term in the Company’s 2020 Stock Plan, as successor to the Company’s Amended and Restated 2012 Stock Plan. “Good Reason” means the employee’s termination of employment within ninety (90) days following the expiration of any cure period following

the occurrence, without the employee’s consent, of one or more of the following: (i) a material reduction in the employee’s base compensation (except where there is a reduction applicable to all similarly situated executive officers generally); provided, that a reduction of less than ten percent (10%) will not be considered a material reduction in base compensation; or (ii) a material breach by the Company of a material provision of the CIC Agreement. “Cause” is defined as a (i) felony indictment or guilty or nolo contendere plea relating to a felony; (ii) fraud or embezzlement; (iii) willful misfeasance or dishonesty; (iv) other action or criminal conduct which materially and adversely affects the business or financial condition of the Company; or (v) a performance failure that is not corrected within 15 days of written notice from the Chief Executive Officer or the Board of Directors.
Section 280G. In the event that any of the payments or benefits provided under the CIC Agreements or otherwise would constitute an “excess parachute payment” as defined in Section 280G of the Code, the payments or benefits under such agreements will be reduced to the maximum level that would not result in an excise tax under Section 4999 of the Code, if such reduction would cause the executive to retain an after-tax amount in excess of what would be retained if no reduction were made.
Restrictive Covenants. Each of the executives is prohibited from revealing confidential information of the Company and disparaging the Company. In addition, the executives are prohibited from (i) competing with the Company or its affiliated companies while employed by the Company and for a period of 6 months following separation of employment and (ii) soliciting clients or hiring employees of the Company or its affiliated companies while employed by the Company and for a period of two years following separation of employment.
Potential Payments for Termination Following a Change-in-Control
The table below summarizes the potential change-in-control benefits that would become payable to each of the NEOs as of December 31, 2024 pursuant to such NEO’s employment agreement or severance and change in control agreement, as applicable, that was in effect on December 31, 2024, and under such executive’s equity award agreements (“Equity Agreements”).
In calculating these benefits, we assumed a change in control of the Company on December 31, 2024. To the extent relevant, the amounts are based on the Company’s closing share price on the last trading day of 2024 of  $26.88 per share.

CEO Pay Ratio
​
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K under the Exchange Act, we are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of our CEO. The CEO to median employee pay ratio included in this information is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K under the Exchange Act. Given the different methodologies that various public companies use to determine an estimate of their pay ratio, the estimated ratio reported below should not be used as a basis for comparison between companies.

​ | Median Employee Total Compensation (except the CEO) | ​ | ​ | ​ | ​ | $73,906 | ​ | ​
​ | CEO Total Annualized Compensation | ​ | ​ | ​ | ​ | $3,317,486 | ​ | ​
​ | Ratio of CEO to Median Employee Compensation | ​ | ​ | ​ | ​ | 44.9 | ​ | ​

For purposes of identifying the median employee, an employee roster as of December 31, 2024 was used to determine the employee population. Gross wages from 2024 were used as the compensation measure. Wages were annualized for those employees who were not employed for the full year of 2024, and also for those employees who were on an unpaid leave of absence during 2024. The median employee was selected from the annualized roster. The roster included 2,096 employees, approximately 4.6% of whom were scheduled to work less than 40 hours per week. There has been no change to our employee population or employment compensation arrangements that we believe would significantly impact this pay ratio.

As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K under the Exchange Act, we are providing the following information about the relationship between the compensation actually paid to our NEOs and certain financial performance of the Company. The compensation actually paid to our NEOs as reported in this section of the Proxy Statement does not reflect the actual amount of compensation earned by or paid to the NEOs, but is a calculation derived from the total compensation reported for the NEOs in the Summary Compensation Table, as adjusted pursuant to the requirements of 402(v) of Regulation S-K under the Exchange Act.

​
(A)
The grant date fair value of equity awards represents the total of the amounts reported in the “Stock Awards” column in the Summary Compensation Table for the applicable year.
​
(B)
The equity award adjustment includes the addition (or subtraction, as applicable) of the following: (i) the year-end fair value of any equity awards granted in the year that are outstanding and unvested as of the end of the year; (ii) the amount of change as of the end of the year (from the end of the prior fiscal year) in fair value of any awards granted in prior years that are outstanding and unvested as of the end of the year; (iii) for awards that are granted and vest in same year, the fair value as of the vesting date; (iv) for awards granted in prior years that vest in the year, the amount equal to the change as of the vesting date (from the end of the prior fiscal 2 year) in fair value; (v) for awards granted in prior years that are determined to

fail to meet the applicable vesting conditions during the year, a deduction for the amount equal to the fair value at the end of the prior fiscal year; and (vi) the dollar value of any dividends or other earnings paid on stock awards in the year prior to the vesting date that are not otherwise reflected in the fair value of such award or included in any other component of total compensation for the year. The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant. The amounts deducted or added in calculating the equity award adjustments are as follows:

​ | Year | ​ | ​ | Year End Fair Value of Equity Awards Granted in Year and Unvested at Year-End ($) | ​ | ​ | Year over Year Change in Fair Value of Outstanding and Unvested Equity Awards ($) | ​ | ​ | Fair Value as of Vesting Date of Equity Awards Granted and Vested in the Year ($) | ​ | ​ | Year over Year Change in Fair Value of Equity Awards Granted in Prior Years that Vested in the Year ($) | ​ | ​ | Fair Value at the End of the Prior Year of Equity Awards that Failed to Meet Vesting Conditions in the Year ($) | ​ | ​ | Value of Dividends or other Earnings Paid on Stock or Option Awards not Otherwise Reflected in Fair Value of Total Compensation ($) | ​ | ​ | Total Equity Award Adjustments ($) | ​

​
(C)
The amounts included in this column are the amounts reported in “Change in Pension and Nonqualified Deferred Compensation” column of the Summary Compensation Table.
​
(D)
The total pension benefit adjustment includes the aggregate of two components: (i) the actuarially determined service cost for services rendered by the NEOs during the year (the “service cost”); and (ii) the entire cost of benefits granted in a plan amendment (or initiation) during the year that are attributed by the benefit formula to services rendered in periods prior to the plan amendment or initiation (the “prior service cost”), in each case, calculated in accordance with U.S. GAAP. The amounts deducted or added in calculating the pension benefit adjustments are as follows:
​

​ | Year | ​ | ​ | Average Service Cost ($) | ​ | ​ | Average Prior Service Cost ($) | ​ | ​ | Average Total Pension Benefit Adjustments ($) | ​
​ | 2024 | ​ | ​ | ​ | ​ | 49,948 | ​ | ​ | ​ | ​ | ​ | 0 | ​ | ​ | ​ | ​ | ​ | 49,948 | ​ | ​

Cumulative Total Shareholder Return (“TSR”) is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period.
​
6.
Represents the weighted peer group TSR, weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The Company uses the KBW Regional Banking Index (KBW Index) as the peer group for determining performance with each of its compensation metrics. The KBW Index is made up of approximately 50 regional banks located throughout the country that are generally within an asset and market capitalization range comparable to the Company.
​
7.
The dollar amounts (in thousands) reported represent the amount of net income reflected in the Company’s audited financial statements for the applicable year.
​
8.
While the Company uses numerous financial and nonfinancial performance measures for the purpose of evaluating performance for the Company’s compensation programs, the Company has determined that Return on Assets is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link compensation actually paid to the company’s NEOs, for the most recently completed fiscal year, to Company performance.
​
Financial Performance Measures
As described in greater detail in “Executive Compensation — Compensation Discussion and Analysis,” the metrics that the Company uses for both our long-term and short-term incentive awards are selected based on an objective of incentivizing our NEOs to increase the value of our enterprise for our shareholders. The most important financial performance measures used by the Company to link executive compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to the Company’s performance are as follows:
▪
Return on Assets
​
▪
Classified Assets as a percentage of Total Assets
​
▪
Earnings per Share Growth
​
▪
Relative TSR
