Forward-Looking Statements and Website References: This proxy statement contains forward-looking statements. Forward-looking statements can be identified by words such as “anticipates,” “intends,” “plans,” “seeks,” “believes,” “estimates,” “expects,” “target,” “projects,” “outlook,” “forecast,” “will,” “may,” “could,” “should,” “can,” and similar references to future periods. In particular, forward-looking statements include, but are not limited to, statements we make about our expectations for our operations and business and our corporate responsibility progress, plans, and goals (including environmental and human capital matters). Forward-looking statements are not based on historical facts, but instead represent our current expectations and assumptions regarding our business, the economy and other future conditions. The inclusion of such statements is not an indication that these contents are necessarily material to investors or required to be disclosed in the Company’s filings with the Securities and Exchange Commission. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. Actual results may differ materially from our forward-looking statements due to several factors. Factors that could cause our actual results to differ materially from our forward-looking statements are described in our Annual Report on Form 10-K for the year ended December 31, 2022. We caution you, therefore, against relying on any of these forward-looking statements. They are neither statements of historical fact nor guarantees or assurances of future performance. Any forward-looking statement made by us speaks only as of the date on which it is made. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. We undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise, and notwithstanding any historical practice of doing so, except as may be required by law. In addition, historical, current, and forward-looking sustainability-related statements may be based on standards for measuring progress that are still developing, internal controls and processes that continue to evolve, and assumptions that are subject to change in the future.

First Financial Bankshares, Inc. - 3 - 2023 Proxy Statement

Record Date

Our Board of Directors has established the close of business on March 1, 2023, as the record date for determining the shareholders entitled to notice of, and to vote at, the annual meeting. On the record date, we had 142,701,931 common shares outstanding. Each of our shareholders is entitled to one vote for each common share held as of the record date.

Quorum

In order for any business to be conducted at the annual meeting, a quorum consisting of shareholders having voting rights with respect to a majority of our outstanding common shares on the record date must be present in person or by proxy. For purposes of determining the presence or absence of a quorum, we intend to count as present shares present in person but not voting and shares for which we have received proxies but for which holders thereof have abstained. Furthermore, shares represented by proxies returned by a broker holding the shares in nominee or “street name” will be counted as present for purposes of determining whether a quorum is present, even if the shares are not entitled to be voted on matters where discretionary voting by the broker is not allowed (“broker non-votes”).

If a quorum is not present at the annual meeting, we will adjourn the meeting, and the Board of Directors will continue to solicit proxies.

Required Vote

As discussed in more detail under “Proposal 1 - Election of Directors,” each director is required to be elected by the affirmative vote of a majority of the votes cast at the annual meeting and entitled to vote on this matter. Withheld votes have the effect of voting against the director nominee. Shares not represented at the annual meeting will have no effect on the election of directors. Brokers are not entitled to vote on director elections, and thus broker non-votes are not treated as votes cast and will have no effect on the election of directors.

The matter described in “Proposal 2 - Ratification of Appointment of Independent Auditors” is required to be approved by the affirmative vote of the majority of the votes cast at the annual meeting and entitled to vote on this matter. Abstentions and shares not represented at the meeting will not be counted for purposes of determining whether such matter has been approved. Brokers may vote in their discretion on this proposal on behalf of clients who have not furnished voting instructions. As a result, broker non-votes will not arise in connection with and will have no effect on this proposal.

With respect to “Proposal 3 - Advisory, Non-Binding Vote on the Compensation of Named Executive Officers,” the affirmative vote of a majority of the votes cast at the annual meeting and entitled to vote on this matter is required for approval of the compensation of our named executive officers. Voting for Proposal 3 is being conducted on an advisory basis, and, therefore, the voting results will not be binding on the Company, the Board of Directors, or the Compensation Committee. Abstentions, broker non-votes, and shares not otherwise represented at the meeting will have no effect on the outcome of such matter.

With respect to “Proposal 4 – Advisory, Non-Binding Vote on Frequency of Executive Compensation Vote,” we are asking shareholders whether the advisory vote on executive compensation should occur every three years, every two years or every year. The option of once every three years, every two years or every year that receives the greatest number of votes will be the frequency approved by shareholders. Voting on Proposal 4 is being conducted on an advisory basis, and, therefore, the voting results will not be binding on the Company, the Board or the compensation committee. Abstentions, broker non-votes, and shares not otherwise represented at the meeting will have no effect on the outcome of such matter.

The Board of Directors unanimously recommends that you vote "FOR" the election of all eleven director nominees, "FOR" the ratification of the appointment of our independent auditors, "FOR" the resolution approving the compensation of our named executive officers AND "FOR" THE ADVISORY VOTE ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS TO OCCUR EVERY (1) YEAR.

Failure to Provide Specific Voting Instructions

If you are a shareholder of record and you properly sign, date, and return a proxy card, but do not indicate how you wish to vote with respect to a particular nominee or proposal, then your shares will be voted FOR the eleven director

First Financial Bankshares, Inc. - 4 - 2023 Proxy Statement

nominees, FOR the ratification of the appointment of our independent auditors, FOR the resolution approving the compensation of our named executive officers, and for the advisory vote on the compensation of our named executive officers to occur EVERY (1) YEAR.

Shareholder List

A list of shareholders registered with our stock transfer company entitled to vote at the annual meeting, which will show each shareholder’s address and the number of shares registered in his, her, or its name, will be open to any shareholder to examine for any purpose related to the annual meeting. Any shareholder may examine this list at our principal office, 400 Pine Street, Suite 310, Abilene, Texas 79601, during ordinary business hours commencing April 15, 2023, and continuing through the date of the annual meeting.

SOLICITATION AND REVOCABILITY OF PROXIES

Solicitation

We will bear the expense to solicit proxies, which will include reimbursement of expenses incurred by brokerage firms and other custodians, nominees, and fiduciaries to forward solicitation materials regarding the annual meeting to beneficial owners. Our officers and directors may further solicit proxies from shareholders and other persons by telephone, electronic communication, or other means. We will not pay these officers and directors any extra compensation for participating in this solicitation. We may engage Georgeson LLC to assist us with the solicitation of proxies and if so, would expect to pay that firm approximately $20,000 for their services, plus out-of-pocket expenses.

Proxies and Revocation

Each executed and returned proxy card will be voted according to the directions indicated on that proxy card. If no direction is indicated, the proxy will be voted according to the Board of Directors’ recommendations, which are contained in this proxy statement. The Board of Directors does not intend to present and has no information that others will present any business at the annual meeting that requires a vote on any other matter. If any other matter requiring a vote properly comes before the annual meeting, the proxies will be voted in the discretion of the proxy holders in accordance with the terms of the proxy.

Each shareholder giving a proxy has the power to revoke it at any time before the annual meeting is called to order. Shareholders of record may change their vote or revoke their proxy by:

•delivering to the Company at any time before the annual meeting is called to order, by our corporate secretary, a written notice of revocation addressed to First Financial Bankshares, Inc., 400 Pine Street, Abilene, Texas 79601, Attention: Corporate Secretary;

•attending the annual meeting and voting in person, and any earlier proxy will be revoked. Your attendance alone at the annual meeting will not revoke your proxy unless you give written notice of revocation to the corporate secretary of the Company before the annual meeting is called to order.

If your shares are held in “street name,” and you desire to change any voting instructions you have previously given to the record holder of the shares of which you are the beneficial owner, you should contact the broker, bank, or other nominee holding your shares in “street name” in order to direct a change in the manner your shares will be voted.

First Financial Bankshares, Inc. - 5 - 2023 Proxy Statement

SUMMARY OF ENVIRONMENTAL, SOCIAL, AND GOVERNANCE (“ESG”) ACTIVITIES

For over 133 years, First Financial has been committed to making our communities better with the core belief that strong, vibrant communities are at the foundation of our success today and in the future. While this commitment is not new, our actions continue to demonstrate leadership in the communities we serve. We are extremely proud of our associates who demonstrate this core belief by being engaged and connected through our common purpose of excellence in customer service while creating our vision of being the employer of choice.

We continue to assess our ESG activities utilizing overall materiality assessments developed with our ESG advisory consultants. This assessment is being used to guide our ongoing approach to ESG activities. As part of this process, we are working towards more formal reporting utilizing the Sustainability Accounting Standards Board (SASB) commercial bank standards under the guidance and oversight of the Nominating/Corporate Governance Committee and Board of Directors.

Commitment to Employees

As of December 31, 2022 we had 1,415 full time and 86 part time employees located in Abilene and our 12 regions throughout Texas. We know our employees are one of our greatest assets and they are foundational to our current and future success. We are committed to maintaining competitive compensation in our markets. During 2022, we evaluated our hourly wages and increased minimum pay for many of our employees that work directly with customers in our branches or provide customer service in our call center.

Our employee benefits focus on providing ongoing health and wellness benefits including not only physical but mental health services with access to telemedicine, funded health savings accounts, employee assistance programs that offer confidential emotional support and work-life solutions. We also provide programs that emphasize and protect financial wellness through our profit-sharing plan and generous 401(k) matching policy. The Company has a robust employee recognition program that highlights employees that create “Wows” for our customers as well as recognizes employees that save customers from fraudulent activity, known as “Fraudbusters.”

Employee training is fundamental to our vision and is one of our 21 Service Non-Negotiables. We believe that “knowledge of our job and the financial industry is essential in providing the appropriate expertise. We encourage our employees to take advantage of the numerous training opportunities available to them and obtain certifications and degrees for current and future roles. During 2022, we provided over 27,000 internally developed training programs. Our employees also completed approximately 27,000 classes through the American Bankers Association (ABA). In addition, we have a generous college tuition reimbursement program to assist employees in obtaining degrees that will open opportunities at higher levels in our Company. In the past 5 years, we have provided tuition assistance to 127 employees.

The Company values the recruitment and retention of a diverse and inclusive workforce that is representative of the communities that we serve. Our focus on diversity, equity and inclusion is also included in our 21 Service Non-Negotiables. By promoting and fostering a workforce that we believe is reflective of our customers and communities, we seek to better understand the financial needs of our prospects and customers and provide them with relevant financial service products. This philosophy enables us to provide different solutions to issues where we can achieve the greatest outcome. We will continue to be an organization that embraces diversity and provides an employee experience that is inclusive and where we treat each other with grace, understanding and acceptance. As of December 31, 2022, 30% of our leadership positions were held by women and 14% were held by ethnic minorities.

Our People

First Financial Bankshares, Inc. - 6 - 2023 Proxy Statement

Our Governance

We are committed to operating with robust corporate governance and ethical business practices. We continually work to improve the effectiveness of our Board and regional boards of directors and management teams as well as our corporate governance policies and activities.

Board Composition and Activities

All but one of our 11 nominees to the Board are independent under NASDAQ rules. In addition, 30% of the independent nominees are female, minority or both which allows for diverse perspectives and experiences.

The lead outside director transitioned during 2022 with Murray Edwards, assuming that role. Mr. Edwards has been a Board member since 2006 and has significant risk management, merger and acquisitions, and strategic planning skills.

Each of the twelve bank regions, plus two divisions, have local advisory boards. These boards include 32 female and or minority directors out of a total of 158 outside board members.

ESG oversight is provided by the Nominating/Corporate Governance Committee which has established a formal set of Corporate Governance Guidelines. ESG activities were reported to the Board quarterly in 2022.

We have established a Risk Appetite statement that is monitored and reported to the Risk Committee annually or more often as needed.

Information Security

The Information Security Program uses a variety of safeguards to protect the confidentiality, integrity and availability of information. The program uses a formal set of industry standards to protect data, and the Information Security Program’s information security standards are reviewed, updated and re-approved annually. The Company regularly assesses the threats and vulnerabilities to its environment so it can update and maintain its systems and controls to effectively mitigate these risks. Layered security controls are designed to complement each other to protect customer information and transactions. There are regular tests of the control environment using internal and external assessment methods such as penetration testing and more targeted assessments to ensure its controls are working as expected.

The Company has a robust information security awareness program. All Company employees are trained on cyber and fraud threats at New Employee Orientation and receive daily information security tips via email. Employees also receive monthly awareness video training and annual computer-based training. The Company also provides information security awareness training to business customers and individuals in our communities.

The Company’s system of internal controls also incorporates a protocol for the appropriate reporting and escalation of information security matters to management and the Board of Directors, to ensure effective and efficient resolution and, if necessary, disclosure of any matters. The Board of Directors is actively engaged in the oversight of the Company’s continuous efforts to reinforce and enhance its operational resilience and receives education to ensure that their oversight efforts accommodate for the ever-evolving information security threat landscape. The Board of Directors monitors the Company’s information management risk policies and practices primarily through its Risk Committee, which oversees areas of operational risk such as information technology activities; risks associated with development, infrastructure, and cybersecurity; oversight of information security risk assessments, strategies, policies, and programs; and disaster recovery, business continuity, and incident response process.

First Financial Bankshares, Inc. - 7 - 2023 Proxy Statement

Our Communities

The Company has always had the philosophy that we are only as good as the communities which we serve. We strive to improve the quality of life in every community that is in our footprint. We support schools, cities, counties, nonprofits and churches with the latest in financial services, as well as our time and money. We encourage our employees to be active in communities and charitable organizations by being on their boards, volunteering their time and helping raise funding. The impact our team has is highlighted by our annual Day of Service, where we had 1,056 employees serve 80 organizations across our footprint.

In addition to volunteering, the Company provided over $2.4 million in support to charitable organizations and schools during 2022 and over $23 million in the past 10 years. We also committed $5.5 million out of a $9 million investment to fund a low-income senior living project south of downtown in Abilene, Texas, which is home to our corporate offices.

We are committed to expand access to financial services in underserved majority minority and low-income areas within our footprint by providing financial literacy, fraud and home ownershp classes. The Company developed an Individual Tax Identification Number (ITIN) residential mortgage loan product for legal immigrants in late 2021, to help them achieve the dream of home ownership. We have continued to emphasize this product in our markets and grow this program and other affordable housing loan products throughout 2022.

Our Environment

We are committed to operating our Company responsibly and understand that this creates long-term sustainable value for our Company by reducing costs, increasing revenue, reducing risks, enhancing our reputation, strengthening our communities, and helping us meet the expectations of our shareholders, our customers, our communities, as well as future generations.

We recognize the environmental impact associated with our use of natural resources and the importance of resource efficiency and conservation. Several of the communities we serve have faced drought conditions where conservation of water is at a premium. Therefore, we strive to operate efficiently, reducing our reliance on natural resources, and wherever possible diverting our waste from landfills through recycling and reuse.

Over the last few years, we have upgraded lighting in our facilities to LED lights and low-heat emission bulbs. We also work with a third-party vendor to shred and recycle most of the paper we use as part of our privacy program and to reduce environmental impact. In 2022, we shredded and recycled about 140,000 pounds of paper.

Environmental concerns also inform our decisions on product offerings. We have continued to emphasize e-Statement enrollment for depository accounts which has increased to 59% of total deposit accounts and 50% of deposit customers access accounts digitally.

Of these shares, the Trust Company had sole voting power with respect to 5,540,291 shares, or 3.88%, of the outstanding common shares of the Company, the Trust Company shared voting authority with respect to 170,943 shares, or 0.12% of the outstanding common shares of the Company and the Trust Company has contingent right to vote under the Company’s Employee Stock Ownership Plan up to 2,131,056 shares, or 1.49%, of the outstanding common shares of the Company. The shares held by the Trust Company which are registered in its name or in the name of its nominee, are associated with many different accounts, each of which is governed by a separate instrument or instructions that set forth the powers of the Trust Company with regard to the shares held in such accounts. The Board of Directors historically has not attempted and does not intend to attempt in the future, to exercise any power to vote such shares except as prescribed under the Company’s Employee Stock Ownership Plan for those shares allocated to the stock account of an Employee Participant under such Plan for which no voting instructions have been timely received.

See “Proposal 1—Election of Directors—Nominees” and “—Executive Officers” for information with respect to the beneficial ownership of our common shares by each director nominee and named executive officers as of March 1, 2023. In the aggregate, all director nominees and executive officers as a group (19 individuals) beneficially owned 5,862,544 shares of our common stock, or 4.11%, of our total outstanding shares, as of March 1, 2023.

Director Compensation

For 2022, we had ten non-employee directors who received fees for attendance at Board of Director meetings and committee meetings. Directors who are also our executive officers or employees receive no compensation for service as members of either the Board of Directors or committees thereof. Director fees were paid as follows:

Description	Annual ($)
Annual Cash Retainer fee (paid quarterly)		50,000
Annual Restricted Share grant		60,000
Board Meeting fee		3,000
Committee Meeting fee		1,500
Lead Director fee		20,000
Chair Fee:
Audit Committee		20,000
Compensation Committee		15,000
Nominating/Corporate Governance Committee		15,000
Risk Committee		15,000

Director fees are paid in cash, but a director may elect to defer receipt of fees into a non-qualified “Rabbi Trust” wherein the funds are used to purchase Company common shares on the open market. Because these shares are held in a “Rabbi Trust,” shares under this plan are not included in the director’s shares beneficially owned as disclosed on page 19. As of December 31, 2022, the Rabbi trust held 404,565 shares in trust for the Company’s directors. On April 26, 2022, each non-employee director received 1,481 shares of Company common shares with respect to their annual $60,000 restricted share grant under the 2021 Omnibus Plan approved by shareholders on April 27, 2021. The closing Company stock price on issuance date was $40.53 and vests from issuance date to the 2023 shareholder meeting on April 25, 2023. Non-employee directors do not participate in the Company’s profit sharing or other benefits. Directors are reimbursed for actual travel costs to attend the respective meetings. In addition, a director serving on the board of a subsidiary or a regional advisory board receives director and committee fees per meeting, which are included in the table below. Director compensation for the year ended December 31, 2022, was as follows:

Name	Fees Earned or Paid in Cash ($)		Stock Awards ($)		Total ($) (1)
April Anthony		75,500		60,000		135,500
Vianei Braun		80,100		60,000		140,100
David Copeland		121,000		60,000		181,000

CORPORATE GOVERNANCE

Overview

We have long believed that good corporate governance is important to ensure that the Company is managed for the long-term benefit of our shareholders. We periodically review our corporate governance policies and practices and compare them to those suggested by various authorities in corporate governance and the practices of other public companies. We also monitor new and proposed rules of the Securities and Exchange Commission, the Nasdaq, and the bank regulatory authorities. We may amend our governance policies and procedures when required by law, Nasdaq rules, or when we otherwise deem it prudent to do so. Each of our Audit, Compensation, and Nominating/Corporate Governance and Risk Committees has adopted a charter. Our corporate governance policies, including our code of conduct applicable to all our employees, officers, and directors, as well as the charters of our Audit, Compensation, Nominating/Corporate Governance, and Risk Committees, are available at www.ffin.com under the “Investor Relations/Shareholder Information/Governance Documents” section. Copies of these documents are also available in print to any shareholder who requests them in writing.

Board Leadership Structure and Role in Risk Oversight

We are committed to a strong, independent Board of Directors and believe that objective oversight of the performance of our management is a critical aspect of effective corporate governance. As described under “Director Independence” below, we believe that all our directors are independent apart from Mr. Dueser given his position as Chairman, President, and Chief Executive Officer. Apart from our Executive Committee, which Mr. Dueser chairs, all our committees are comprised solely of and chaired by independent directors. In addition, at each regularly scheduled Board meeting, the non-management directors meet in executive sessions without management directors.

Mr. Dueser serves as our Chairman of the Board of Directors and Chief Executive Officer of the Company. The Company believes that Mr. Dueser’s leadership has served the Company and its shareholders well and that despite Mr. Dueser's status as an executive of the Company, the overall benefit of Mr. Dueser's leadership in both roles outweighs any potential disadvantage of this structure, and that any concerns are mitigated by existing safeguards, including:

•the designation of a Lead Independent Director with clearly defined authority, duties and responsibilities;

•the highly regulated nature of the Company’s operations;

•the fact that the Board is comprised of experienced and skilled directors, all of whom, other than Mr. Dueser, are independent;

•the fact that the Board’s Audit, Compensation, Nominating/Corporate Governance and Risk Committees consist entirely of independent directors; and

•regular reviews of the Board’s leadership structure and governance practices.

Independent Lead Director

Mr. Edwards serves as our Lead Independent Director. The Board of Directors recognizes that the Company and its shareholders are well served under corporate governance best practices through the designation and empowerment of an independent lead director for several reasons, the foremost being that Mr. Dueser, our Chairman of the Board, is a non-independent director. The independent lead director’s duties include:

•chairing meetings of executive sessions of our Board of Directors, as well as other meetings involving non-management and independent directors;

•presiding at meetings of the Board of Directors in the absence or at the request of the Chairman of the Board of Directors;

•acting as a liaison between the independent directors and the Chairman of the Board of Directors;

•approving meeting agendas;

First Financial Bankshares, Inc. - 21 - 2023 Proxy Statement

•ensuring that appropriate information is sent to the Board of Directors;

•providing an important communication link between the other independent directors and our shareholders; and

•calling additional meetings of the independent directors as appropriate.

Mr. Edwards serves as a liaison between the Chairman and the independent directors, presides over executive sessions of the Board and consults regularly with the Chairman on significant corporate decisions. The Board of Directors periodically considers its structure and the role and responsibilities of the independent lead director to reflect its commitment to corporate governance best practices.

The Board of Directors, together with the Audit, Compensation, Executive, Nominating/Corporate Governance and Risk Committees, coordinate with each other to provide enterprise-wide oversight of our management and handling of risk. These committees regularly report to the entire Board of Directors on risk-related matters and provide the Board of Directors with integrated insight about our management of strategic, credit, interest rate, financial reporting, technology (including cybersecurity), liquidity, compliance, operational and reputational risks. In addition, our subsidiary bank has its own board of directors (which is comprised of the same members as the Company's Board of Directors) and audit, compensation, directors’ loan, and asset-liability management committees, which provide risk management oversight. The management and board of directors of our subsidiary bank also provide reports to our management and Board of Directors regarding risk management oversight.

In addition, the consolidation of the management of our securities portfolio, loan review, internal audit, compliance, technology, and asset-liability/liquidity management at the holding company level provides additional risk oversight, which further mitigates overall risk to the Company. The Board of Directors believes that sound credit underwriting to manage credit risk and a conservative investment portfolio to manage liquidity and interest rate risk contribute to effective oversight of the Company’s risk. Enterprise risk is monitored through our Risk Appetite Statement. Furthermore, as a financial holding company responsible for safeguarding sensitive information, our Board of Directors believes a robust cybersecurity strategy is vital to effective cyber risk management. Accordingly, our Board is actively engaged in the oversight of the Company’s cyber risk profile and key cyber initiatives.

At meetings of the Board of Directors and its committees, directors receive regular updates from management regarding risk management. Mr. Dueser and the executive officers, who are responsible for instituting risk management practices that are consistent with our overall business strategy and risk tolerance, lead management’s risk discussions at Board and committee meetings. Outside of formal meetings, the Board of Directors, its committees, and individual Board members have regular access to senior executives, including all executive officers.

Minimum Share Holdings

In October 2018, the Nominating/Corporate Governance Committee established minimum common shareholdings for its non-employee directors. Directors are required to own common shares of the Company common having a value equal to five times the annual cash retainer fee. The stock ownership level must be achieved within the later to occur of (a) October 23, 2023 (i.e., the fifth anniversary of the date of adoption of the minimum ownership guidelines), or (b) five years after their first election as a director. Directors are expected to accumulate the required number of shares ratably over the applicable five-year period. Once achieved, the minimum share ownership amount should be maintained as long as the person serves as a director of the Company.

Failure to maintain the minimum requirements of the guidelines may result in a director receiving future payments of director fees in the form of equity until he or she has satisfied the minimum ownership guidelines. The Board of Directors may also bar the director from selling Company shares until the minimum share guidelines have been achieved. On December 31, 2022, each non-employee director, except Ms. Braun and Dr. Jones, met the minimum shares holdings, including applicable phase-in periods. Ms. Braun joined the Board of Directors in January 2020 and Dr. Jones joined in January 2022 and have not yet reached their minimum stock holdings but each expects to comply over the five year period.

The complete “Stock Ownership Guidelines” can be found at www.ffin.com in the “Investor Relations/Shareholder Information/Governance Documents” section.

First Financial Bankshares, Inc. - 22 - 2023 Proxy Statement

Hedging and Pledging Policies

The provision of our insider trading policy applicable to our directors, executive officers, and certain other designated employees prohibits such person from trading in puts, calls, or other derivative securities or engaging in short sales with respect to our securities. Our insider trading policy also prohibits such persons from holding our securities in a margin account; however, in some circumstances, such persons may be permitted to pledge our securities as collateral so long as such securities are not held in a margin account.

Communications with Your Board of Directors

Shareholders may call or write to the Board of Directors at the address and phone number listed on the first page of this proxy statement. Letters addressed to individual board members and clearly marked as shareholder communications will be forwarded by the corporate secretary unopened to the individual addressee. Any letters addressed to the Board of Directors and clearly marked as shareholder communications will be forwarded by the corporate secretary unopened to the Chairman of the Board.

Director Independence

In accordance with Nasdaq rules, our Board of Directors affirmatively determines the independence of each director and each nominee for election as a director. The Board of Directors makes its determination based on the elements of independence set forth in the Nasdaq listing standards. We have not adopted any supplemental independence criteria.

Based on these standards, the Board of Directors has determined that each of the following non-employee directors is independent:

April K. Anthony	Eli Jones, Ph.D.
Vianei Lopez Braun	I. Tim Lancaster
David L. Copeland	Kade L. Matthews
Mike B. Denny	Robert C. Nickles
Murray H. Edwards	Johnny E. Trotter

All members of the Audit, Compensation, Nominating/Corporate Governance, and Risk Committees are independent under the applicable Nasdaq listing standards. Given his position as Chairman, President, and Chief Executive Officer, Mr. Dueser is not considered an independent director.

Meetings of the Board of Directors

The Board of Directors of the Company has four regularly scheduled meetings each year. In 2022, each of the directors attended at least 75% of the meetings of the Board of Directors and the committees of the Board of Directors on which such director served.

Although we do not have a formal policy regarding attendance by members of the Board of Directors at our annual meeting of shareholders, we encourage directors to attend, and historically substantially, all directors have done so. All directors attended the 2022 annual meeting of shareholders.

First Financial Bankshares, Inc. - 23 - 2023 Proxy Statement

Committees of the Board of Directors

The Board of Directors has five committees. The functions and current members of each committee are as follows:

Executive Committee. The Executive Committee acts for the Board of Directors between board meetings, except to the extent limited by our bylaws or Texas law. The current members are Messrs. Copeland, Dueser, Edwards, Lancaster, Nickles and Trotter. Mr. Dueser is the chair of the committee. The Executive Committee met four times during 2022 and once in January 2023.

Nominating/Corporate Governance Committee. Among other things, the Nominating/Corporate Governance Committee recommends director candidates to the Board of Directors. The Nominating/Corporate Governance Committee members are Messrs. Copeland, Edwards, Lancaster, Nickles, and Trotter. Mr. Edwards is the chair of the committee. The committee met twice in 2022 and met once in January 2023.

Historically, our goal has been to assemble a Board of Directors that brings diverse perspectives and skills derived from exemplary business and professional experience and diversity of backgrounds and viewpoints. Such qualifications provide sound and prudent guidance with respect to our operations and interests. Generally, the committee identifies candidates through the personal, business, and organizational contacts of the directors and management, as well as our regional advisory board members. For a description of the process of identifying and evaluating potential directors, please refer to the section of this proxy statement entitled “Identifying and Evaluating Nominees for Director” on page 9.

Our Corporate Governance Guidelines provide that an individual may not stand for election or reelection as a director upon attaining seventy-five (75) years of age. Otherwise, there are no stated minimum criteria for director nominees. We expect that the Nominating/Corporate Governance Committee will recommend nominees in the future by first evaluating the current members of the Board of Directors willing to continue in service. Current members of the board with skills and experience that are relevant to our business and who are willing to continue in service will be considered for re-nomination, balancing the value of continuity of service by existing members of the board with that of obtaining a new perspective. If any member of the board does not wish to continue in service or if the Nominating/Corporate Governance Committee of the Board of Directors decides not to re-nominate a member for re-election, we anticipate that the Nominating/Corporate Governance Committee will identify the desired skills and experience and diversity of a new nominee in light of the criteria above and begin a search for appropriately qualified individuals. To date, we have not engaged third parties to identify or evaluate or assist in identifying potential nominees, although we reserve the right in the future to retain a third-party search firm if determined by the Nominating/Corporate Governance Committee.

The Nominating/Corporate Governance Committee will consider qualified director candidates recommended by shareholders. For the 2024 annual shareholders meeting, any shareholder wishing to propose a nominee should submit a recommendation in writing to the Nominating/Corporate Governance Committee of First Financial Bankshares, Inc. at 400 Pine Street, Suite 300, Abilene, Texas 79601 at least 120 days and not more than 150 days in advance of the anniversary of the 2023 annual meeting (or as otherwise set forth in our amended and restated bylaws), including the nominee’s resume, qualifications and other relevant biographical information and providing confirmation of (1) the name and address of the shareholder giving notice, and any (x) person controlling, directly or indirectly, or acting in concert with, the shareholder, (y) any beneficial owner of the shares of the Company owned of record or beneficially by the shareholder and (z) any person controlling, controlled by or under common control with the shareholder (a “Shareholder Associated Person”), (2) for the shareholder and any Shareholder Associated Person, the number of common shares of the Company that are owned beneficially and of record and any derivatives, hedged positions, synthetic and temporary ownership techniques, swaps, securities loans, timed purchases and other economic and voting interests or similar positions, securities or interests with respect to our securities, (3) the nominee’s consent to serve as a director and acknowledgement that the nominee will comply with our amended and restated bylaws, code of business conduct and ethics, corporate governance handbook and any other applicable rules, regulations, policies or standards of conduct applicable to the Board of Directors and its members, (4) a description of all relationships, arrangements or understandings between the shareholder and any Shareholder Associated Person, on the one hand, and the nominee, the nominee’s affiliates or associates or others acting in concert with the nominee, on the other hand, (5) a description of the nominee’s background and experience and the reasons why the nominee meets the standards for director nominees set forth in our corporate governance practices, (6) a completed independence questionnaire regarding the nominee, which may be obtained from the Secretary of the Company, (7) a written representation from the nominee that they do not have, nor will they have,

First Financial Bankshares, Inc. - 24 - 2023 Proxy Statement

any undisclosed voting commitments or other arrangements with respect to their actions as a director and (8) any other information regarding the nominee or shareholder that would be required to be included in a proxy statement relating to the election of directors. Qualified candidates recommended by our shareholders will be evaluated on the same basis as candidates recommended by our officers, directors, and other sources.

The Company is committed to promoting diversity and inclusiveness in identifying candidates for Board service and in the overall makeup of the Board and is committed to including in each candidate search qualified individuals who reflect diverse skills, professional disciplines, and backgrounds, including race, gender, and ethnic diversity. Our Nominating/Corporate Governance Committee is also responsible for overseeing our strategy and initiatives regarding ESG matters and promoting a culture of corporate social responsibility consistent with the Company’s mission and vision.

Audit Committee. Among other things, the Audit Committee reviews the scope and results of the annual audit by our independent auditors and receives and reviews internal and external audit reports. The committee also monitors the qualifications, independence, and performance of our independent auditor and internal auditors. Its members include Ms. Anthony and Messrs. Copeland, Denny, and Lancaster. Mr. Copeland is the chairman of the committee. The Audit Committee met five times in 2022, once in January 2023 and once in February 2023. The Board of Directors has determined that it believes all Audit Committee members are financially literate under the current listing standards of Nasdaq. The Board of Directors also believes Mr. Copeland and Ms. Anthony qualify as an “audit committee financial expert” as defined by the Securities and Exchange Commission rules adopted pursuant to the Sarbanes-Oxley Act of 2002.

Compensation Committee. The members of the Compensation Committee include Ms. Braun, Dr. Jones and Messrs., Lancaster, Matthews, and Trotter. Mr. Lancaster is the chairman of the committee. All committee members are deemed to be independent. In determining the independence of the members, the Board of Directors has used independence requirements specified by Nasdaq Rule 5605(d)(2)(A) and has applied this definition consistently to all committee members. The committee meets as needed during the year but generally meets four to five times per year. The Compensation Committee met four times during 2022, twice in January 2023 and once in March 2023. The Compensation Committee charter can be found on our website at www.ffin.com in the “Investor Relations/Shareholder Information/Governance Documents” section.

The Compensation Committee is responsible for making recommendations to the Board of Directors concerning compensation matters for the Company’s executive officers and directors. Executives of the Company are integral in the compensation process for the Company; however, the committee determines all elements of pay for the Chairman, President, and Chief Executive Officer. With the assistance of the Chief Financial Officer and the human resources department, the Chairman, President, and Chief Executive Officer makes recommendations for all Company executives, including the named executive officers, to the committee for their review and approval. For the named executive officers, the committee develops compensation recommendations to the full Board of Directors for approval.

The Compensation Committee also oversees the administration of employee benefits and benefit plans for the Company and its subsidiaries, including our profit sharing and flexible spending plans as well as our 2021 Omnibus Plan, 2015 Restricted Stock Plan, and 2012 Incentive Stock Option Plan for key employees. The committee delegates day-to-day administration of the clerical elements of these programs to the human resources department, Trust Company as trustee of the profit sharing plans, and other executive officers overseeing the equity plans.

The agenda for meetings of the Compensation Committee is set by its chairman, acting with the assistance of the Company’s Chairman, President, and Chief Executive Officer, and Chief Financial Officer. At each meeting, the committee meets in executive sessions without management or any non-independent directors. In making compensation decisions, the Compensation Committee obtains information from a variety of public sources and considers the recommendations of the Company’s management, human resources department, and trust company. The committee makes periodic reports to the full Board of Directors.

The Compensation Committee has from time to time engaged compensation consultants from outside the Company, and the committee has the right under its charter to engage compensation consultants or other outside advisors, including legal counsel if it so chooses, subject to ratification by the Board of Directors, and only after consideration of the factors listed in Nasdaq Rule 5605(d)(3)(D). The committee may retain, terminate, and approve professional fees (subject to ratification by the Board of Directors) related to compensation consultants or other advisors as appropriate. In 2020, the Compensation Committee retained Pearl Meyer to assist the Company in addressing

First Financial Bankshares, Inc. - 25 - 2023 Proxy Statement

compensation and benefits to executive officers and outside directors of the Company. Prior to their engagement, the Compensation Committee confirmed that Pearl Meyer did not have any known potential or actual conflicts of interest with the Board of Directors or the Company.

Risk Committee. The members of the Risk Committee include Ms. Braun and Messrs. Copeland, Edwards, Matthews, and Nickles. Mr. Nickles is the chairman of the committee. The Board formed the Risk Committee in 2021, and the Committee met for the first time in January 2022 and a total of four times in 2022 and once in January 2023. The purpose of the Risk Committee of the Board of Directors of First Financial Bankshares, Inc. is to assist the Board in its oversight of the Company’s overall risk framework, risk appetite, and the senior management’s identification, measurement, monitoring, and controlling key risks facing the Company and its subsidiaries.

Compensation Committee Interlocks and Insider Participation

No person who served as a member of the Compensation Committee was, during 2022, an officer or employee of the Company or any of its subsidiaries or had any relationship requiring disclosure in this proxy statement. However, certain of the Compensation Committee members (or related entities) maintained loans from subsidiaries during 2022. The loans were made in the ordinary course of business, on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions on an arms-length basis and did not involve more than the normal risk of collectability or present other unfavorable features to the subsidiary bank. None of our executive officers served as a member of the compensation committee (or other board committee performing equivalent functions or, in the absence of any such committee, the entire Board of Directors) or director of another entity, one of whose executive officers served as a member of our Board of Directors.

Management Succession Planning

Management succession planning is a priority of the Company as it allows the Company to provide continuity in leadership. The Company’s succession plan is designed to identify and prepare a diversified group of candidates for high-level management positions that become vacant as a result of retirement, resignation, death, disability, or the pursuit of new business opportunities. On at least an annual basis, management assesses (and reports to the Board of Directors) the leadership needs of the Company to ensure the selection of qualified leaders who are diverse and possess the necessary skills to serve as a member of the Company’s senior staff. Management is responsible for the Company’s succession planning for each member of senior staff, required regulatory position, and other critical roles, identifying potential candidates to fill future vacancies in those positions. When making succession plans, and in order to create a diverse pool of applicants, the Company will strive to promote a diverse pool of candidates for employment, including women and minorities.

PROPOSAL 2 – RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

The Audit Committee of your Board of Directors has selected Ernst & Young LLP to serve as our independent auditors for the year ending December 31, 2023, and to serve until the next annual meeting in April 2024. Ernst & Young LLP has served as the Company’s independent auditors since 2002. We have been advised by Ernst & Young LLP that neither its firm nor any of its members has any financial interest, direct or indirect, in us, nor has had any connection with us or any of our subsidiaries in any capacity other than independent auditors. The Board of Directors recommends that you vote for the ratification of the selection of Ernst & Young LLP. Shareholder ratification of the selection of Ernst & Young LLP as our independent auditors is not required by our certificate of formation, bylaws, or otherwise.

Independent Registered Public Accounting Firm

We retained Ernst & Young LLP to serve as our independent registered public accounting firm for 2022 and 2021. The aggregate fees billed for each of the last two fiscal years for professional services rendered by Ernst & Young LLP, the principal auditors who performed the audit of our annual financial statements, review of the quarterly financial statements, and audit of internal controls, were as follows:

	Year ended December 31,
	2022		2021
Audit Fees	$	1,052,200	$	976,391
Audit Related Fees	None		None
Tax Fees	None		None
All Other Fees	None		None

Our Audit Committee has adopted a policy that requires advance approval of all audit, audit-related, tax services, and other services performed by the independent auditor. The policy provides for pre-approval by the Audit Committee of specifically defined audit and non-audit services. Except as permitted under Rule 2-01 of Securities and Exchange Commission Regulation S-X, unless the specific service has been previously pre-approved with respect to that year, the Audit Committee must approve the permitted service before the independent registered public accounting firm is engaged to perform it. The Audit Committee has delegated to its Chairman the authority to approve permitted services provided that the Chairman reports such decisions to the committee at its next scheduled meeting.

Nevertheless, your Board of Directors is submitting this matter to the shareholders in conformance with the practices of good corporate governance. If the shareholders do not ratify the appointment of Ernst & Young LLP, then the appointment of independent auditors will be reconsidered by our Audit Committee. Even if the appointment is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent audit firm at any time during the year if it is determined that such a change would be in the best interests of the Company and its shareholders. Representatives of Ernst & Young LLP are expected to be present at the annual shareholders' meeting, and they may have the opportunity to make a statement if they desire to do so and to respond to appropriate questions.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS THE COMPANY’S INDEPENDENT AUDITORS FOR THE YEAR ENDING DECEMBER 31, 2023.

PROPOSAL 3 – ADVISORY, NON-BINDING VOTE ON THE COMPENSATION OF NAMED EXECUTIVE OFFICERS

Pursuant to the Securities and Exchange Commission rules adopted under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), we are conducting a shareholder advisory vote on the compensation paid to our named executive officers. Although the vote is advisory and is not binding on the Board of Directors, the Company, or the Compensation Committee, the Board’s Compensation Committee will take into account, among other criteria, the outcome of the vote when considering future executive compensation decisions.

This proposal, commonly referred to as a “say-on-pay” proposal, gives our shareholders the opportunity to express their views on the compensation of our named executive officers and the executive compensation philosophy, policies, and programs described in this proxy statement. We ask that you support the compensation of our named executive officers as disclosed under the heading “Executive Compensation,” including the “Compensation Discussion and Analysis” section and the accompanying compensation tables and related narrative disclosure.

As described in the Compensation Discussion and Analysis section, we seek to provide a compensation package that attracts and retains executive talent, provides rewards for superior performance, and produces consequences for underperformance. We believe that our compensation program strikes the appropriate balance between utilizing responsible, measured pay practices and effectively incentivizing our named executive officers to dedicate themselves fully to value creation for our shareholders.

You are encouraged to read the detailed information under “Executive Compensation” beginning on page 32 of this proxy statement for additional details about our executive compensation programs. We believe shareholders should consider the following in determining whether to approve this proposal:

•each member of our Compensation Committee is independent under the applicable Nasdaq rules;

•the Compensation Committee continually monitors our performance and adjusts compensation practices accordingly;

•all award agreements, after October 2016, evidencing awards granted under the 2012 Incentive Stock Option Plan, the 2015 Restricted Stock Plan, or the 2021 Omnibus Stock and Incentive Plan include a compensation recoupment (“clawback”) provision; and

•all bonuses and awards are subject to repayment or forfeiture pursuant to the Company’s Compensation Recovery Policy, as further discussed on page 42, should the Company be required to prepare an accounting restatement.

Shareholder advisory votes on executive compensation currently take place on an annual basis.

The Board of Directors strongly endorses the Company’s executive compensation program and recommends that shareholders vote in favor of the following resolution:

RESOLVED, that the shareholders of First Financial Bankshares, Inc. hereby approve, on an advisory basis, the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K in the Company’s Proxy Statement for the 2023 Annual Meeting of Shareholders, including the Compensation Discussion and Analysis compensation tables and narrative discussion.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL OF THE RESOLUTION RELATED TO THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS.

First Financial Bankshares, Inc. - 28 - 2023 Proxy Statement

PROPOSAL 4 – ADVISORY, NON-BINDING VOTE ON FREQUENCY OF THE ADVISORY VOTE ON EXECUTIVE COMPENSATION

Pursuant to the Securities and Exchange Commission rules adopted under the Dodd-Frank Act, we are conducting a shareholder advisory vote on the frequency of the “say-on-pay vote” contained in Proposal 3. This shareholder advisory vote is required to be conducted every six years.

In particular, we are asking whether shareholders would prefer that the “say-on-pay” advisory vote occur every three years, every two years or every year. However, because the vote is advisory, it is not binding on the Board or the Company in any way, but will be considered in setting the frequency in the future.

At our 2017 shareholders meeting, which was the last time our shareholders voted on the frequency of the say-on-pay advisory vote, our shareholders selected “every year” as their preference by a vote of 65.4% of votes cast. The “every two years” option received 1.0% and the “every three years” option received 33.6%.

After consideration of this proposal, the Board has again determined that an advisory vote that occurs every year is the most appropriate alternative for the Company, and therefore, the Board recommends that you vote for a one-year interval for the advisory vote on executive compensation. Please note that you are not being asked to approve or disapprove the Board’s recommendation, but rather to indicate your own choice of one, two or three years for this proposal.

In formulating its recommendation, the Board considered that an annual advisory vote on executive compensation will allow the Company’s shareholders to provide us with their direct input on our compensation philosophy, politics and practices as disclosed in the proxy statement each year. Additionally, an annual advisory vote is consistent with the Board’s desire to implement “best practices” with respect to corporate governance. We understand that shareholders may have different views as to what is the best approach for the Company, and we look forward to again hearing from shareholders on this proposal.

When casting your vote on your preferred voting frequency for advisory vote of named executive officer compensation, you may choose one of the following four options: “every year,” “every two years,” “every three years,” or “abstain”:

RESOLVED, that the option of once every year, two years or three years that receives the highest number of votes cast for this resolution will be determined to be the preferred shareholder frequency with which the Company is to hold an advisory vote of the shareholders on the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis compensation tables and narrative discussion.

2022 Say on Pay Results and Shareholder Engagement

Say-on-Pay Considerations. The Compensation Committee monitors the results of the annual advisory "say-on-pay" proposal and incorporates such results as one of many factors considered in connection with the discharge of its responsibilities, although no such factor is assigned a quantitative weighting. Because a substantial majority (99.0% of votes cast) of our shareholders approved the compensation program described in our proxy statement in 2022, the Compensation Committee did not implement changes to our executive compensation program as a result of the shareholder advisory vote.

First Financial Bankshares, Inc. - 34 - 2023 Proxy Statement

Shareholder Outreach. We value the opinion of our shareholders and look forward to a continued, open conversation on compensation and related matters, and other issues relevant to our business. We want our shareholders to fully understand our rationale for our approach to executive compensation, and we want to understand the views and concerns of our shareholders. Although our current executive compensation program contains continuations or versions of arrangements that were put in place historically, we continue to evolve the design and features based on current best practices and shareholder feedback.

WHAT GUIDES OUR COMPENSATION PROGRAM

Compensation Philosophy & Objectives

The Compensation Committee’s philosophy is to provide a compensation package that attracts and retains executive talent, provides rewards for superior performance, and discourages underperformance. It is also the Compensation Committee’s practice to provide a balanced mix of short- and long-term compensation and cash and equity-based compensation that the committee believes appropriate to mitigate excessive risk-taking and align the short- and long-term interests of the Company’s executives with that of its shareholders and encourage executives to participate and perform as equity owners of the Company.

We believe that to attract and retain the quality of executive talent necessary to achieve our long-term strategic business goals; we must offer a competitive compensation package to our executives. The Compensation Committee seeks to attract executive talent by offering competitive base salaries, annual performance incentive opportunities, and long-term awards under the Company’s long-term incentive programs (including profit sharing, employee stock ownership plan, restricted stock units (“RSUs”) and performance stock units (“PSUs”), and stock options). The Compensation Committee reviews the range of total compensation in the market for various positions. Executive compensation is based on factors including the competitive market for talent, responsibilities, skills, experience, and performance. We consider the executive’s scope of responsibilities, skills and experience, overall Company performance, and the Board of Directors’ evaluation of the executive’s individual performance. Based on our business strategy and the results we expect from our executives, we attempt to blend their compensation pay between short- and long-term pay as well as the mix of cash and equity compensation to promote our short- and long-term business objectives. We believe the design of our compensation programs and the amounts paid have been and continue to be appropriate and reasonable. We continually review our programs to ensure they are aligned with our business objectives and shareholder interests.

It is the Compensation Committee’s practice to provide incentives that promote both the short- and long-term financial objectives of the Company. To motivate our executives to achieve our strategic business goals, we offer the opportunity to earn the targeted level of pay through incentive compensation that correlates to the Company’s short- and long-term performance. These incentives are based on financial and investment metrics underlying Company performance, including earnings growth, return on assets, return on equity, net interest margin, credit quality metrics, and efficiency ratio. Annual bonuses reward achievement of short-term objectives based on the Company’s operational business plan that are established to encourage our executives to make decisions currently that promote shareholder value. Long-term incentive programs encourage executives to focus on the Company’s long-term strategic goals, which are catalysts to drive sustainable long-term shareholder value while accomplishing a high level of retention of our executives. Our compensation program also accounts for individual performance, which enables the Compensation Committee to differentiate among executives and emphasize the link between personal performance and compensation.

Compensation Decision-Making Process

Role of Compensation Committee. Our Compensation Committee has the primary responsibility for approving our compensation philosophy and programs as they relate to our executive officers, including the named executive officers (“NEOs”). The Compensation Committee is comprised of independent, non-employee members of the Board of Directors. The Compensation Committee works very closely with the independent consultant and management to examine the effectiveness of the Company’s executive compensation program throughout the year. Details of the Committee’s authority and responsibilities are specified in the Compensation Committee’s Charter, which is available on our website at www.ffin.com in the “Investor Relations/Shareholder Information/Governance Documents.”

The Compensation Committee makes all final compensation and equity award decisions regarding our executive officers, except for the Chief Executive Officer (“CEO”), whose compensation is determined by the independent members of the full Board of Directors, based upon recommendations of the Compensation Committee.

First Financial Bankshares, Inc. - 37 - 2023 Proxy Statement

Role of Senior Management. Members of our management team attend regular meetings where executive compensation, Company, and individual performance, and competitive compensation levels and practices are discussed and evaluated. The Committee and subsequently the independent members of the Board of Directors review the CEO’s performance and make all final determinations regarding the CEO's compensation after conducting their review; for other executive officers, the Committee reviews the CEO’s assessment of their performance and proposed pay decisions. Only the Committee members are allowed to vote on decisions regarding executive officer compensation.

Role of the Independent Consultant. The Compensation Committee has the sole authority to retain, terminate, obtain advice from, oversee, and compensate its outside advisors, including its compensation consultant. The Compensation Committee has the funding it needs for these purposes.

The Compensation Committee retained Pearl Meyer in 2022 to serve as its independent executive compensation consultant. The services provided by Pearl Meyer include advising the Compensation Committee on the principal aspects of the executive compensation program and evolving best practices, and providing market information and analysis regarding the competitiveness of our program design and awards in relation to our performance.

None of the Company’s management team participated in the Compensation Committee’s decision to retain Pearl Meyer. Pearl Meyer reports directly to the Compensation Committee, and the Compensation Committee may replace Pearl Meyer or hire additional consultants at any time.

The Compensation Committee regularly reviews the services provided by its outside consultants and believes that Pearl Meyer is independent in providing executive compensation consulting services. The Compensation Committee conducted a specific review of its relationship with Peal Meyer in 2022 and determined that Pearl Meyer’s work for the Compensation Committee did not raise any conflicts of interest, taking into account the “independence factors” identified by the SEC and Nasdaq. The Compensation Committee continues to monitor the independence of its compensation consultant on a periodic basis.

In 2022, Pearl Meyer prepared an executive compensation report with regard to the named executive officers and provided information on market practices for executive and outside director compensation.

Role of Competitive Benchmarking. The Compensation Committee measures the Company’s senior management compensation levels with comparable compensation levels in industry benchmark studies and peer group data. We use survey data to benchmark our executive positions to those at other banking institutions with total asset sizes similar to ours.

The Compensation Committee evaluates the Company's named executive officer compensation levels with comparable compensation levels for a peer group of comparable banks based on asset size, geography and operations. The peer group companies considered by the Compensation Committee are:

·	FB Financial Corporation	·	Origin Bancorp, Inc.	·	Southside Bancshares, Inc.
·	Hilltop Holdings, Inc.	·	Prosperity Bancshares Corporation	·	Stellar Bancorp, Inc.
·	Home Bancshares, Inc.	·	Renasant Corporation	·	Trustmark Corporation

The Company’s other Regional Bank Chief Executive Officers and Presidents are also included in this bonus program, and their goals are structured to specific situations for their respective region.

The Compensation Committee met in January 2023 to establish the specific goals for 2023 bonus plans for the named executive officers. Such 2023 goals were based on similar criteria as 2022; however, the target and maximum levels were increased for Mr. Butler and Mr. Thaxton, the target and maximum levels were increased to 60 percent and 80 percent, respectively; and for Mr. Longhofer, the target and maximum levels were increased to 50 percent and 70 percent, respectively.

Mr. Dueser's target and maximum levels remained unchanged from the prior year at 90 percent and 110 percent, respectively.

Long-term Incentives (Equity Grants)

Stock Options. We presently offer stock options under the 2021 Omnibus Plan approved by shareholders in 2021. We believe that stock options are an appropriate long-term incentive to link executives’ performance with stock price appreciation. Grants made under the 2021 Omnibus Plan vest 20% annually over five years, commencing on the first anniversary of the grant and expiring ten (10) years from the grant date. Unvested options granted under the 2021 Omnibus Plan vest immediately upon the occurrence of a change of control event, as defined in the 2021 Omnibus Plan. Unexercised options granted under the 2021 Omnibus Plan are cancelled should the officer be terminated with cause, as defined in the 2021 Omnibus Plan.

We encourage the grantee not to dispose of the shares obtained through the exercise of the options but rather to keep and build an equity interest in the Company. Incentive stock options further encourage our executives to exercise their options and hold the resulting shares by giving them the opportunity for favorable tax treatment for the exercise gain if certain holding requirements are met.

Historically, the Compensation Committee, based in part on discussions with the Company’s Chief Executive Officer, granted options every two years, subject to the Board of Directors’ approval. However, starting in 2021, the Company changed the cadence of option awards and is expected to make grants to its executive officers and other key employees on an annual basis. In August 2022, the Company granted key employees, including the named executive officers disclosed herein, an aggregate of 240,583 stock options. Allocation of options is based on competitive market considerations, past and expected performance of the executive, affordability, and retention considerations. Grantees are required to sign confidentiality, non-solicitation, and non-competition agreements in connection with the receipt of the option grants to preclude actions detrimental to the Company.

The Compensation Committee does not grant options during any black-out period under our Insider Trading Policy. We do not release material, non-public information for the purpose of affecting the value of executive compensation, nor do we grant options to executives in coordination with the release of material, non-public

First Financial Bankshares, Inc. - 40 - 2023 Proxy Statement

information. All awards of the Company’s common shares under the 2021 Omnibus Stock Incentive Plan were made at the closing market price on the day of the award.

Beginning with stock options granted in 2017, the Compensation Committee established compensation recoupment, or clawback provisions, in all stock option award agreements. Pursuant to the clawback provisions, a grantee may, based on the decision of the Board of Directors, forfeit the right to receive and/or retain the benefit of the resultng equity compensation awarded if, during the grantee’s employment or thereafter, a determination is made by the Board of Directors that the grantee has breached his or her duties to the Company, including, by way of example, a breach of the Company’s Code of Business Conduct and Ethics Policy, engaged in serious misconduct, improper dissemination of Company confidential information or has disparaged the Company or others.

Restricted Stock Units (“RSUs”) and Performance Stock Units (“PSUs”). Historically, the Company had issued restricted shares to executives and others under the 2015 Restricted Stock Plan previously approved by our shareholders. With the approval of the 2021 Omnibus Stock and Incentive Plan by our shareholders in April 2021, we now have the flexibility to offer other forms of equity grants. In consultation with our compensation consultant regarding market practices and a desire by our Compensation Committee to shift our historical equity grant practices, we issued 16,209 RSUs and 16,209 PSUs to our named executive officers and 24,833 RSUs and 24,833 PSUs in the aggregate to selected executives and others during 2022.

Both the RSUs and PSUs generally vest in a change in control, death, and other events as defined in the award agreement. The award agreements also require the grantee to agree to defined noncompetition restrictions with respect to the Company and non-solicitation of the Company’s employees and customers, as well as agreeing that the awards are subject to the Company’s claw back and recoupment policies described below. Upon vesting as described, each unit is converted into one share of the Company’s stock.

The RSUs include time-based vesting equally over a three-year period following the date of grants; the RSUs include dividend equivalent rights, which are distributable with the vesting of the shares but do not include voting rights.

The PSUs vest at the end of a three-year periods ending December 31, 2023, and 2024, respectively, to be settled no later than March 15, 2024, and 2025, respectively, with the number of earned PSUs determined based on the Company's relative performance to a peer group comprised of all U.S. banks with assets between $10 and $50 billion. The performance measures are weighted as follows: 50% relative to adjusted earnings per share growth; and 50% relative to the adjusted return on average assets over the three-year period. The number of earned PSUs is determined as the product of (A) the target number of PSUs and (B) the sum of the applicable adjusted earnings per share growth vesting percentage and the applicable adjusted return on average assets vesting percentage. The applicable earnings per share growth vesting percentage and the adjusted return on average assets vesting percentage are determined as follows:

Company Percentile Performance Relative to Peer Group	Adjusted Earnings Per Share Growth Vesting Percentage(1)			Adjusted Return on Average Assets Vesting Percentage(1)
Below 25th		0	%		0	%
Equal to or above 25th, but below 50th		25	%		25	%
Equal to or above 50th, but below 75th		50	%		50	%
75th or over		100	%		100	%

(1)The applicable vesting percentage for performance between the 25th and 50th percentiles and between the 50th and 75th percentiles is determined by straight-line linear interpolation.

OTHER COMPENSATION PRACTICES, POLICIES, AND PROGRAMS

Stock ownership guidelines

In October 2018, the Nominating/Corporate Governance Committee established minimum common share holdings for the Company’s executive officers. The chief executive officer is required to own shares of Company stock having a value equal to five times his base salary. The other executive officers are required to own shares of Company stock having a value equal to three times their base salary. The stock ownership level must be achieved within the later to occur of (a) October 23, 2023 (i.e., the fifth anniversary of the date of adoption of these guidelines), or (b) five years after first becoming an executive officer. The executive officers are expected to accumulate the required number of shares over the applicable five-year period. Once achieved, ownership of the guidelines amount should be maintained as long as the individual remains an executive officer.

Failure to maintain the minimum requirements of the guidelines may result in an executive officer receiving future cash bonuses in the form of equity until he or she has satisfied the guidelines. The Company may also bar the executive officer from selling Company shares until the guidelines have been achieved. However, neither of these alternatives shall be exercised if the executive officer has not sold any shares.

The complete “Stock Ownership Guidelines” can be found at www.ffin.com in the “Investor Relations/Shareholder Information/Governance Documents.”

Compensation Recovery Policy

In October 2018, the Compensation Committee approved a Compensation Recovery Policy whereby the Company’s executive officers subject to Section 16 of the Exchange Act, the presidents of the Company’s subsidiaries or a regional division of the Bank and the regional chairpersons of the Bank will generally be subject to repayment or forfeiture of any incentive compensation (as defined below) should the Company be required to prepare an accounting restatement such that the applicable person would have received a lesser incentive compensation amount. Incentive compensation, as defined in the policy, means all bonuses and other incentive and equity compensation awarded based on the application of objective performance criteria. The complete “Compensation Recovery Policy” can be found at www.ffin.com in the “Investor Relations/Shareholder Information/Governance Documents” section.

Retirement Plans

401(k), Profit Sharing Plan and Employee Stock Ownership Plan. All employees of the Company who satisfy the plan’s eligibility conditions participate in the defined contribution plan. The 401(k) feature of the plan allows the participants to make pre-tax contributions to the plan. The plan includes a “safe harbor” Company matching contribution equal to 100% of each participant’s contributions not exceeding 3% of the participant’s compensation, plus 50% of each participant’s deferral contributions in excess of 3% but not in excess of 5% of the participant’s compensation. Discretionary profit sharing contributions are determined annually based on a formula that includes growth in net income.

Contributions under the profit sharing plan are reviewed by the Compensation Committee and are subject to their discretion and recommendation for approval by the Board of Directors. The Compensation Committee oversees the administration of the plan. Under the profit sharing plan, contributions by employees are not required as a condition of participation. Each participating employer’s annual contribution is allocated among the accounts of the eligible plan participants, in the ratio that each participant’s compensation bears to the total compensation of all eligible participants. Compensation is defined as the total amount paid to an employee during the year, including bonuses, commissions, and overtime pay (and includes certain deferrals allowed under the plan), but excluding reimbursed expenses, group insurance benefits, and profit sharing contributions. However, the Internal Revenue Service limits the compensation amount used to calculate a participant’s benefit to a maximum of $305,000 for 2022 (adjusted annually by the Internal Revenue Service). Additionally, the annual amount (which is the aggregate of employer and employee contributions) that may be allocated to a participant is limited to $61,000 ($67,500 if age 50 or over) for 2022 (adjusted annually by the Internal Revenue Service).

Our plan also includes an employee stock ownership plan (“ESOP”) component whereunder participants are initially allocated 25% of their annual profit sharing contributions into Company common shares and given the option to receive cash dividends on shares beneficially owned by them in the ESOP in cash or reinvest the dividends in

First Financial Bankshares, Inc. - 42 - 2023 Proxy Statement

additional shares. Each participant beneficially owns the shares held in their ESOP account and is entitled to vote his or her shares in any shareholder vote.

The profit sharing plan provides for benefits to vest in graduated percentages, with benefits being fully vested after six years of credited service except for amounts contributed to an employee’s account under the safe harbor provisions and shares resulting from the reinvestment of dividends in the ESOP which are immediately fully vested. Generally, an employee’s benefit will be the contributions allocated to their account while a participant, increased by gains and decreased by losses from investments of the plan, and increased by any forfeitures allocated to their account. An employee is always fully vested with respect to any voluntary contributions he or she makes. The plan also provides for immediate vesting upon attainment of normal retirement age and/or upon death or disability. If a participant terminates employment for any other reason, the total amount of their employee contribution account and the vested portion of his or her employer contribution account become distributable.

Senior management eligible for participation in the plan receives the same benefits as all employees. The maximum employer profit sharing contribution to the plan for an individual in a single year is 15% of the individual’s eligible salary, plus the safe harbor Company match, subject to Internal Revenue Service limits.

Supplemental Executive Retirement Plan. The Company adopted a Supplemental Executive Retirement Plan (the “SERP”), effective January 1, 2019. The SERP is a non-qualified deferred compensation plan designed as a top-hat plan to benefit certain key senior executives of the Company who are selected by the Board to participate, including each of our named executive officers. The SERP is intended to provide a benefit from the Company upon retirement, death, disability, or voluntary or involuntary termination of services (other than “for cause”), subject to the requirements of Section 409A of the Internal Revenue Code. Under the SERP, the Company may, but is not required to, make discretionary contributions to the executive’s accounts from time to time. The contributions may be fully vested or subject to vesting conditions imposed by the Board of Directors with respect to the contributions; provided, however, that all unvested amounts credited to an executive’s account will become fully vested upon the executive’s death or disability or upon the occurrence of a change of control (as defined in the SERP). Company contributions to the SERP on behalf of an executive are credited with earnings and losses based on the executive’s investment elections. The investment options under the SERP are currently the same as those offered under the Company’s profit sharing plan, except that Company stock is not an available investment option under the SERP. An executive’s vested account is payable to the participant following his or her termination in a single lump sum or installments, as elected by the participant in accordance with the requirements of Section 409A of the Internal Revenue Code. The Company made contributions totaling $445,000 to the SERP in January 2023 for the year ended December 31, 2022, for all participants, including the named executive officers.

Effective January 1, 2022, the SERP plan was amended to allow designated participants by the Compensation Committee to defer cash salary and short-term incentives and restricted and performance stock units into the SERP based on their indicated elections.

Make Whole Plan. The Company has a frozen non-qualified “excess benefit” plan whereunder executives, whose Company contributions to the profit sharing plan and employer match under the 401(k) feature were curtailed due to Internal Revenue Service limitations, received contributions from the Company equal to the amount under qualified plans as if there had been no Internal Revenue Service limitations. This plan used the same contribution formula and vesting requirements as the 401(k) plan and was 100% vested in the Company’s common stock. This plan was implemented by the Compensation Committee to allow senior management whose compensation was in excess of Internal Revenue Service limits to have profit sharing/401(k) matches in the same proportionate ratio as all employees. The Make Whole Plan was “frozen” as to new participants and contributions effective December 31, 2018. At December 31, 2022, the plan held 114,177 of the Company’s common shares.

First Financial Bankshares, Inc. - 43 - 2023 Proxy Statement

Executive Recognition Agreements and Potential Payments Upon a Change in Control. In April 1996, our Board of Directors unanimously approved an executive recognition plan. This plan enabled us to offer our key executive officers and those of our subsidiaries an executive recognition agreement. All named executive officers have entered into executive recognition agreements with us. The Company does not utilize employment agreements.

We believe our executive recognition agreements are conservative when compared to the competitive market. The agreements have been continually renewed since we view them as necessary to ensure the continued focus of our executives on making the appropriate strategic decisions for the Company, even if the decision involves a change in control.

Each executive recognition agreement provides severance benefits for each applicable executive officer if, within two years following a change in control, the officer’s employment with us or our subsidiaries is terminated (i) by us (including any successor to us) or the subsidiary bank for any reason other than for cause (see below), or (ii) by the executive officer for good reason (see below).

As used in the executive recognition agreements, a “change in control” is defined as one or more of the following:

•a person or entity directly or indirectly acquires securities of the Company representing more than 50% of the combined voting power of the Company's then outstanding voting securities;

•the consummation of a reorganization, merger, consolidation, recapitalization, exchange offer, purchase of assets or other transaction, in each case, with respect to which the persons who were the beneficial owners of the Company immediately prior to such a transaction do not immediately after such transaction, own more than 50% of the combined voting power of the reorganized, merged, recapitalized or resulting company’s then outstanding voting securities;

•the shareholders of the Company approve a plan of complete liquidation or dissolution of the Company and such complete liquidation or dissolution is consummated;

•in any two-year period, individuals who are members of the Board of Directors at the beginning of such period plus each new director whose election or nomination for election was approved by at least two-thirds of the directors in office immediately prior to such election or nomination, cease for any reason to constitute at least a majority of the Board; or

•the sale or disposition by the Company of all or substantially all of the Company’s assets other than a sale or disposition by the Company of all or substantially all of the Company’s assets to an entity at least 50% of the combined voting power of the voting securities of which is owned by persons in substantially the same proportions as their ownership of the Company immediately prior to such sale.

As used in the executive recognition agreements, “cause” means termination of an employee due to the:

•willful and continued failure by the employee to substantially perform his or her duties with the Company (other than any such failure resulting from the employee’s physical or mental incapacity due to injury or illness) after written demand for substantial performance is delivered to the employee by the Company; or

•willful engaging by the employee in conduct, which is demonstrably injurious to the Company, monetarily or otherwise.

As used in the executive recognition agreements, “good reason” means termination by an employee due to:

•a determination by the employee, made in good faith and based on the employee’s reasonable belief, that there has been a materially adverse change in his or her status or position as an executive officer of the Company as in effect immediately prior to the change in control, including, without limitation, any material change in the employee’s status or position as a result of a diminution in the employee’s duties or responsibilities or the assignment to the employee of any duties or responsibilities which are inconsistent with his or her status or position, or any removal of the employee from or failure to reappoint or reelect the employee to such position;

•a material reduction by the Company in the employee’s annual base salary in effect immediately prior to the change in control;

•the relocation of the employee’s principal office outside of the city or metropolitan area in which the employee is residing at the time of any change in control;

First Financial Bankshares, Inc. - 44 - 2023 Proxy Statement

•a material reduction by the Company in the budget over which the employee retained authority immediately prior to a change of control;

•the failure by the Company to provide and credit the employee with the number of paid vacation days to which the employee is then entitled in accordance with the Company’s normal vacation policy as in effect immediately prior to a change in control;

•any action or inaction by the Company following a change in control that constitutes a material breach of the agreement under which the employee provides services to the Company;

•the failure by any successor corporation to the Company to assume the executive recognition agreement; or

•any purported termination of the employee not effected pursuant to a notice of termination as required by the executive recognition agreement.

Such severance benefits under the executive recognition agreements provide that the executive officer will receive a payment equal to a certain percentage (as set forth in his or her executive recognition agreement) of his or her annual base salary immediately preceding the date of termination along with the targeted amount of the employee's bonus prorated through the date of termination and payment of the employee's unused paid time-off. The percentage of annual base salary to be received upon a change in control pursuant to his or her executive recognition agreement is 200% (except for the CEO where this percentage is 300%). The total severance payment for the executive officer cannot, however, exceed the amount that would cause such payment to be deemed a “parachute payment” under Section 280G of the Internal Revenue Code.

The executive recognition agreements were renewed on July 1, 2022, with a term to expire on June 30, 2024. However, if a change in control occurs during the original term of the executive recognition agreements, then the executive recognition agreements will continue in effect for an additional period of two years following the change in control. Similarly, if a second change in control occurs within two years from the date of the first change in control, then the executive recognition agreements will continue in effect for a period of two years from the date of the second change in control. The agreements include confidentiality obligations but do not bind the executives to non-competition, non-disparagement, or non-solicitation clauses.

The executive recognition agreements provide that if any payments or benefits to the employee would constitute a “parachute payment” (as defined in Internal Revenue Code Section 280G(b)(2)) and would be subject to excise tax, then a calculation shall be made comparing (i) the net benefit to the employee after payment of such excise tax to (ii) the net benefit to the employee if payments are limited to the extent necessary to avoid being subject to the excise tax. Only if the amount calculated under (i) above is less than the amount under (ii) above will the payments be reduced to the minimum extent necessary to ensure that no portion of the payment to the employee is subject to the excise tax.

Amounts that would be paid under these agreements upon a change in control and a qualifying termination for good reason using base salary information as of December 31, 2022, for the named executive officers would be as follows:

Name	Amount		Value of Stock Options and Restricted Stock
F. Scott Dueser, Chairman, President, and Chief Executive Officer	$	3,375,000	$	1,599,223
Ronald D. Butler, II, Executive Vice President & CAO	$	1,200,000	$	323,944
James R. Gordon, Executive Vice President & CFO	$	1,240,000	$	338,530
T. Luke Longhofer, Executive Vice President & CLO	$	770,000	$	198,870
Kirk W. Thaxton, President & CEO, First Financial Trust and Asset Management Company, N.A.	$	906,000	$	266,427

In addition to the amounts payable under the executive recognition agreements, the Company’s 2012 Incentive Stock Option Plan, 2015 Restricted Stock Plan, and 2021 Omnibus Plan generally provides that upon a change in control satisfying the requirements of such plan, all unvested stock options will automatically become vested and exercisable in full.

The table above shows our estimates of the value that would have been recognized by our executive officers as a result of the accelerated vesting of our stock options and restricted stock held by such executive officers assuming a change in control occurred on December 31, 2022. The estimated value was calculated by (i) multiplying the

First Financial Bankshares, Inc. - 45 - 2023 Proxy Statement

number of unvested stock options held by the applicable named executive officer by the difference between the closing price of our common shares on December 31, 2022, which was $34.40, and the exercise price of the option and (ii) multiplying the number of unvested restricted shares, RSUs and PSUs and/or held by the applicable named executive officer by the closing price of our common shares on December 31, 2022, which was $34.40. The actual amounts to be paid out can only be determined at the time of such a change in control.

Perquisites and Other Benefits. The primary perquisites for senior management are the reimbursement of initiation fees and dues for one golf or social club. We seek to encourage our senior management to belong to a country club or social club so that they have a convenient entertainment forum for customers and to facilitate interaction with current and potential customers, many of whom belong to these clubs. We do not permit personal use of our Company airplane.

Senior management also participates in the Company’s other benefit plans on the same terms as other employees. These plans include medical, life insurance, and flex spending account benefits. Relocation benefits also are reimbursed but are individually negotiated when they occur.

Severance Benefits. We believe that companies should provide reasonable severance benefits to employees. With respect to senior management, these severance benefits should reflect the fact that it may be difficult for employees to find comparable employment within a short period of time. Our policy for all employees provides that full-time employees who are discharged due to a restructuring or layoff are eligible to receive severance pay based on their years of service to the Company. The Company will provide one week of severance pay for each year of employee service, up to a maximum of six months of salary, except that in all cases, severance pay will not be less than four weeks’ pay. In order to receive severance pay, an employee must sign a release of claims in favor of the Company. Employees who do not sign the required release form will not receive severance pay.

Risk Assessment of Compensation Policies and Practices. In connection with the Compensation Committee’s evaluation and review of the Company’s compensation policies and practices for its officers and employees, as such policies and practices relating to risk management practices and risk-taking incentives, the Compensation Committee has determined that its compensation policies and practices are not reasonably likely to have a material adverse effect on the Company.

Tax Considerations. Although deductibility of compensation is preferred, tax-deductibility is not a primary objective of the Company’s compensation programs. The Company believes that achieving its objectives under the compensation philosophy set forth above is more important than the benefit of tax deductibility. The Company reserves the right to maintain flexibility in how it compensates its executive officers that may result in limiting the deductibility of amounts of compensation from time to time.

(1)Represents annual cash incentive opportunity for 2022; see “Short-term Incentive (Cash Bonus)” section beginning on page 39 above.

(2)Represents performance stock unit (PSU) awards granted under the 2021 Omnibus Stock and Incentive Plan. The threshold, target, and maximum number of shares shown based on the number of PSUs at 25% vesting, 100% vesting, and amount granted, and 200% vesting, respectively, based on each award vesting as described on page 40.

(3)Represents restricted stock unit (RSU) awards granted under the 2021 Omnibus Stock and Incentive Plan. Each award vests one-third at the end of one year, two-thirds at the end of two years, and in full at the end of three years.

(4)Amounts reflect the grant date fair value of the respective award, computed in accordance with the ASC topic 718. Regardless of the value on the grant date, the actual value that may be realized from an award is contingent on the satisfaction of the applicable condition to vesting of that award, and for stock options, also upon the excess of the Company’s stock price over the exercise price. For a discussion of the assumptions used in the valuation of these awards, see note 17 of the notes to consolidated financial statements in our Annual Report on Form 10-K.

CEO Pay Ratio

As required by Item 402(u) of Regulation S-K, we are providing the following information for 2022:

•The median of annual total compensation of all employees of our Company (other than Mr. Dueser, our Chairman, President, and Chief Executive Officer) was $44,250;

•The annual total compensation of Mr. Dueser, our Chairman, President, and Chief Executive Officer, was $3,089,587 (see “Summary Compensation Table” on page 48; and

•Based on this information, the ratio of the annual total compensation of our Chairman, President, and Chief Executive Officer to the median of the annual total compensation of all employees is 69.8 to 1.

To identify the median of the annual total compensation of all our employees, as well as to determine the annual total compensation of our median employee and our Chairman, President, and Chief Executive Officer, we note the following:

•For 2022, our employee population totaled approximately 1,500 individuals. This population consisted of our full-time and part-time employees, as we do not have temporary or seasonal workers. We selected December 31, 2022, as our identification date for determining our median employee because it enabled us to make such identification in a reasonably efficient and economic manner.

•To find the median of the annual compensation of all our employees, we used the salary and wages, including overtime and incentive compensation, from our payroll records for 2022.

•We identified our median employee using this compensation measure, which was consistently applied to all our employees included in this calculation.

Pay Versus Performance

The following tables summarize compensation information for the principal executive officer and average compensation for the other named executive officers required by newly issued SEC rules regarding Pay Versus Performance. The Company uses Annualized Net Income growth as it Company Selected Measure (CSM).

Most Important Performance Measures

Efficiency Ratio

Return on Assets

Return on Equity

Annual Net Income Growth

First Financial Bankshares, Inc. - 55 - 2023 Proxy Statement

As shown in the PVP table below the Company's 3-Year cumulative TSR outperformed the companies included in the industry index. The Company well outperformed the index in all years which is consistent with the Company's 10 year outperformance to the index as illustrated in the 10 Year TSR performance graph included in the Compensation Discussion and Analysis section of this proxy statement.

Total Shareholder Return: Company vs. Peer Group

 

As shown in the chart below, the CEO and other NEOs’ CAP amounts are aligned with the Company’s TSR. This is due primarily to the Company’s use of equity incentives, which are tied directly to stock price in addition to the company’s financial performance.

CAP vs. Total Shareholder Return

 

First Financial Bankshares, Inc. - 56 - 2023 Proxy Statement

As shown in the chart below, the Company’s net income has steadily increased while the CEO and other NEOs’ CAP has varied significantly each year. This is due in large part to the significant emphasis the Company places on equity incentives, which are sensitive to changes in stock price.

CAP vs. Net Income

 

Annualized Net Income Growth (CSM) is a primary driver of short term incentives and relative annualized net income growth is a key component of long term incentives. It is a key driver in both cash incentive bonuses as well as profit sharing amounts. The CEO and the other NEO's net income growth goals are set by the Compensation committee each year. The Company has exceeded prior year earnings in each of the past 3 years. In 2022, the earnings growth goal was not met for the consolidated Company. This significantly reduced cash incentive bonuses for the NEOs for the year ended December 31, 2022.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee oversees our financial reporting process on behalf of the Board of Directors. Management has the primary responsibility for the financial statements and the reporting process, including the system of internal controls. In fulfilling its oversight responsibilities, the committee, which is composed of independent directors in compliance with Rule 5605 of the Nasdaq listing standards, reviewed and discussed the audited financial statements in the Annual Report included with this proxy statement with management. The committee also discussed with management the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements.

The Audit Committee reviewed with Ernst & Young LLP, our independent registered public accounting firm for 2022, who was responsible for expressing an opinion on the conformity of our audited financial statements with generally accepted accounting principles, their judgments as to the quality, not just the acceptability, of our accounting principles and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards and, as applicable, the standards of the Public Company Accounting Oversight Board (PCAOB). The Audit Committee also discussed with the independent registered public accounting firm their audit of the Company’s effectiveness of internal control over financial reporting as of December 31, 2022, based on criteria established in the Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework). In addition, the committee has discussed with the independent registered public accounting firm the auditors’ independence from management and the Company, including the matters required by the Public Company Accounting Oversight Board Auditing Standard No. 1301, “Communications with Audit Committees,” and considered the compatibility of non-audit services with the auditors’ independence. The Audit Committee has received the written disclosures from our independent registered public accounting firm regarding the auditors’ independence required by PCAOB Ethics and Independence Rule 3526, “Communication with Audit Committees Concerning Independence.”

The Audit Committee discussed with our independent registered public accounting firm the overall scope and plans for their audit. The Audit Committee meets with the independent registered public accounting firm, with and without management present, to discuss the results of their examinations, their evaluations of our internal controls, and the overall quality of our financial reporting. The Audit Committee held five meetings during the year that ended December 31, 2022, and met once in January 2023 and once in February 2023.

The Audit Committee has relied, without independent verification, on management’s representation that the financial statements have been prepared with integrity and objectivity and in conformity with generally accepted accounting principles. The Audit Committee’s oversight does not provide it with an independent basis to determine that management has, in fact, maintained appropriate accounting and financial reporting principles or policies. Furthermore, the Audit Committee’s considerations and discussions with management and the independent auditors do not ensure that our financial statements are presented in accordance with generally accepted accounting principles, that the audit of our company’s financial statements has been carried out in accordance with generally accepted auditing standards or the standards of the PCAOB or that our independent accountants are in fact independent.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the annual report on Form 10-K for the year ended December 31, 2022, for filing with the Securities and Exchange Commission. The Board of Directors approved the Audit Committee’s recommendation. The members of the committee are considered independent because we believe they satisfy the independence requirements for audit committee members prescribed by Nasdaq and the Securities and Exchange Commission.

DELINQUENT SECTION 16(a) REPORTS

Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), requires our directors and officers, and persons who own more than 10% of our common shares, to file with the Securities and Exchange Commission initial reports of our common share ownership and reports of changes in such ownership. A reporting person must file a Form 3, Initial Statement of Beneficial Ownership of Securities, within ten (10) days after such person becomes a reporting person. A reporting person must file a Form 4, Statement of Changes of Beneficial Ownership of Securities, within two business days after such person’s beneficial ownership of securities changes, except for certain changes exempt from the reporting requirements of Form 4. A reporting person must file a Form 5, Annual Statement of Beneficial Ownership of Securities, within 45 days after the end of the issuer’s fiscal year to report any changes in ownership during such year not reported on a Form 4, including changes exempt from the reporting requirements of Form 4.

The Securities and Exchange Commission’s rules require our reporting persons to furnish us with copies of all Section 16(a) reports that they file. Based solely on a review of the reports furnished to the Company, the Company believes that during the year ended December 31, 2022, the Company’s officers, directors, and greater than ten percent owners timely filed all reports they were required to file under Section 16(a).

INTEREST IN CERTAIN TRANSACTIONS

As has been true in the past, some of our officers and directors, members of their families, and other businesses with which they are affiliated are or have been customers of one or more of our subsidiaries. As customers, they have entered into transactions in the ordinary course of business with such subsidiaries, including borrowings, all of which were on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions on an arms-length basis. Such borrowings did not involve more than a normal risk of collectability or present any other unfavorable features to the subsidiary bank. None of the transactions involving our subsidiaries and our officers and directors, or other businesses with which they may be affiliated, has been classified or disclosed as nonaccrual, past due, restructured, or potential problems.

The authority of our subsidiary bank to extend credit to our directors, executive officers, and principal shareholders, including their immediate family members and corporations, and other entities that they control, are subject to substantial restrictions and requirements under Section 22(g) and 22(h) of the Federal Reserve Act and Regulation O promulgated thereunder, as well as the Sarbanes-Oxley Act of 2002. These statutes and regulations impose specific limits on the amount of loans our subsidiary banks may make to directors and other insiders, and specified approval procedures must be followed in making loans that exceed certain amounts. In addition, all loans our subsidiary bank makes to directors and other insiders must satisfy the following requirements:

•the loans must be made on substantially the same terms, including interest rates and collateral, as prevailing at the time for comparable transactions with persons not affiliated with us or the subsidiary bank;

•the subsidiary bank must follow credit underwriting procedures at least as stringent as those applicable to comparable transactions with persons who are not affiliated with us or the subsidiary bank; and

•the loans must not involve a greater than normal risk of repayment or other unfavorable features.

Furthermore, our subsidiary bank must periodically report all loans made to directors and other insiders to the bank regulators, and these loans are closely scrutinized by the bank regulators for compliance with Sections 22(g) and 22(h) of the Federal Reserve Act and Regulation O. We have developed written procedures for compliance with these rules. Under the provisions of its charter, the Audit Committee of our Board of Directors is charged with reviewing all other transactions between related parties and us.
