PROXY STATEMENT

These proxy materials are delivered by the Board of Directors (the “Board”) of Enterprise Financial Services Corp (the “Company” or “EFSC”), in connection with the solicitation of proxies to be voted at the 2024 Annual Meeting of Shareholders or any adjournment or postponement thereof. The meeting will be held virtually over the internet on Wednesday, May 1, 2024 at 5:00 p.m. Central Time.
This Proxy Statement and the proxy card were first provided to shareholders on or about March 19, 2024.

QUESTIONS ABOUT THE MEETING AND THESE PROXY MATERIALS

What may I vote on and how does the Board recommend that I vote?

Proposal |  | Board Voting Recommendation
1.The election of 14 directors to hold office until the next annual meeting of shareholders or until their successors are elected and have qualified. |  | FOR all nominees
2.The ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024. |  | FOR
3.An advisory (non-binding) vote to approve executive compensation. |  | FOR

Who can vote at the meeting? The Board has set March 7, 2024 as the record date (the “Record Date”) for the 2024 Annual Meeting. All shareholders who owned our common stock at the close of business on the Record Date may vote at the 2024 Annual Meeting. On the Record Date, there were 37,514,488 shares of common stock outstanding. Shares held as of the Record Date include shares that are held directly in your name as the shareholder of record and those shares held for you as a beneficial owner through a stockbroker, bank or other nominee.
How do I vote my shares? If your shares are registered directly in your name with our stock transfer agent, Computershare, you are considered a shareholder of record and the beneficial owner of those shares. As a shareholder of record, you have the right to grant your voting proxy directly to the Company, or to vote electronically at the meeting. You may submit your proxy by mail, over the internet at www.proxyvote.com, or via the telephone at 1-800-690-6903.
If your shares are held in a stock brokerage account or by a bank, you are still considered the beneficial owner of those shares, but your shares are said to be held in “street name.” Generally, only shareholders of record may vote electronically at the meeting. If your shares are held in “street name,” you will receive a form from your broker or bank seeking instruction as to how your shares should be voted. Many of our shareholders who hold their shares in “street name” through a nominee have the option to submit their proxies or voting instructions to their nominee electronically by telephone or the internet. These shareholders should review and follow the voting instructions provided by their nominee, including any instructions related to revoking your voting instructions. You are also invited to attend the virtual 2024 Annual Meeting. However, since you are not the shareholder of record, you may not vote your shares electronically at the virtual 2024 Annual Meeting unless you obtain a legal proxy from your broker or bank.
Internet availability of proxy solicitation and other 2024 Annual Meeting materials. We are furnishing proxy materials to some of our shareholders via the internet by mailing a Notice of Internet Availability of Proxy Materials, instead of mailing printed copies of those materials. The Notice of Internet Availability of Proxy Materials instructs shareholders that our proxy statement, annual report to shareholders, electronic proxy card and related materials are available for viewing, free of charge, on the internet. Shareholders may then access these materials and vote over the internet or request delivery of a full set of materials
1

by mail or email. These rules help us lower the cost of conducting our 2024 Annual Meeting by reducing costs associated with printing and postage.
We mailed the required Notice of Internet Availability of Proxy Materials (the “Notice”) to shareholders on or about March 19, 2024. The proxy materials will be posted on the internet, at www.proxyvote.com, no later than the day we begin mailing the Notice and through the conclusion of the 2024 Annual Meeting. If you receive the Notice, you will not receive a paper or email copy of the proxy materials unless you request one in the manner set forth in the Notice. The Notice will also include instructions on how to access and review the proxy materials online, how to vote your shares over the internet, and how to get a paper or email copy of the proxy materials, if that is your preference.
Can I change my vote? Yes. If you are the shareholder of record, you may revoke your proxy at any time before the 2024 Annual Meeting of shareholders by:
•entering a new vote by internet or telephone;
•returning a later-dated proxy card;
•sending written notice of revocation to the Corporate Secretary of the Company; or
•attending the virtual 2024 Annual Meeting and voting electronically.
To change your vote for shares you hold in street name, you will need to follow the instructions provided by your broker or bank.
How are shares of common stock voted at the meeting? Each holder of common stock is entitled to one vote for each share of common stock held with respect to each matter to be voted upon.
All shares of common stock represented at the 2024 Annual Meeting by properly executed proxies received prior to or at the 2024 Annual Meeting which are not properly revoked will be voted at the 2024 Annual Meeting in accordance with the instructions indicated on the proxies. If no contrary instructions are indicated, proxies will be voted FOR the election of the Board’s director nominees in Proposal 1, and FOR Proposals 2, and 3.
How many votes are required to elect each director? A plurality of votes cast at the 2024 Annual Meeting is required for the election of each director, which effectively means that the 14 persons receiving the most votes will be elected as directors. If you indicate “withhold authority to vote” for a particular nominee on your proxy card, your shares will not be voted with respect to those nominees indicated; however, your shares will be counted for purposes of determining whether there is a quorum. There is no cumulative voting for our directors. While directors are elected by a plurality of votes cast, our Board has adopted a majority voting policy for directors. This policy states that in an uncontested election, any nominee who receives a greater number of votes “withheld” from his or her election than votes “for” such election is required to submit his or her resignation to the Board. The Nominating and Governance Committee of the Board is required to make recommendations to the Board with respect to any such tendered resignation. The Board will act on the tendered resignation within 90 days from the certification of the vote and will publicly disclose its decision, including its rationale. Only votes “for” or “withheld” are counted in determining whether a majority has been cast in favor of a nominee. If you cast a “withheld” vote, your vote will have a similar effect as a vote against that director nominee under our majority voting policy for directors. If a nominee fails to receive a majority of the votes cast and the Board accepts the director’s resignation, there would be a vacancy created on the Board. Our Board would then have the option under our By-Laws either to appoint someone to fill the vacancy or to reduce the size of the Board.
How many votes are required to adopt the other proposals?
Each outstanding share of our common stock as of the Record Date is entitled to one vote on each proposal at the 2024 Annual Meeting.
If there is a quorum at the 2024 Annual Meeting, the matters, other than the election of directors, to be voted upon by the shareholders require the following votes for such matter to be approved:
•Proposal 2. Ratification of the Company’s Independent Registered Public Accounting Firm. The affirmative vote of holders of the majority of the shares for which votes are cast at the 2024 Annual Meeting is required for the ratification of the appointment of Deloitte & Touche LLP as the independent registered public accounting firm for the year ending December 31, 2024. Abstentions will not be counted as votes cast and, therefore, will not affect the outcome.
•Proposal 3. Advisory (non-binding) Vote on Approval of Executive Compensation. The affirmative vote of holders of the majority of the shares for which votes are cast at the 2024 Annual Meeting is required to approve, on a
2

non-binding advisory basis, the compensation of the Company’s named executive officers. Abstentions and broker “non-votes” will not be counted as votes cast and, therefore, will not affect the outcome.
If a broker indicates on its proxy that it submits to the Company that it does not have authority to vote certain shares held in “street name,” the shares not voted are referred to as “broker non-votes.” Broker non-votes occur when brokers do not have discretionary voting authority to vote certain shares held in “street name” on particular proposals under the rules of the New York Stock Exchange, and the “beneficial owner” of those shares has not instructed the broker how to vote on those proposals. If you are a beneficial owner and you do not provide instructions to your broker, bank or other nominee, your broker, bank or other nominee is permitted to vote your shares for or against “routine” matters such as Proposal 2, the ratification of the appointment of our independent registered public accounting firm. Brokers are not permitted to exercise discretionary voting authority to vote your shares for or against “non-routine” matters. Of the proposals on which shareholders will be asked to vote on at the 2024 Annual Meeting, Proposal 2, the ratification of the appointment of our independent registered public accounting firm, is a “routine” matter, while Proposal 1, the election of directors, and Proposal 3, the advisory vote on approval of executive compensation are “non-routine” matters.
How do I vote if my shares are held in a benefit plan? If you are a current or former employee of the Company or one of its subsidiaries and you have any portion of your investment funds allocated to the EFSC Common Stock Fund in the EFSC Incentive Savings Plan (“Savings Plan”), you may instruct the Savings Plan’s trustees how to vote the shares of common stock allocated to your account under the Savings Plan. You will instruct the voting of your shares in the same manner as other shareholders, i.e., by submitting your voting instructions by telephone or through the internet or by requesting a proxy card to sign and return. Please see the Notice we sent to you or this Proxy Statement for specific instructions on how to provide voting instructions by any of these methods. Please note that your voting instructions for shares held in the Savings Plan must be returned by 11:59 p.m. Eastern Time on April 29, 2024.
What if I don’t give specific voting instructions or abstain?
If you indicate a choice on your proxy on a particular matter to be acted upon, the shares will be voted as indicated.
If you are a shareholder of record and you return a signed proxy card but do not indicate how you wish to vote, the shares will be voted FOR the director nominees in Proposal 1, and FOR Proposals 2, and 3. If you do not return the proxy card, your shares will not be voted and will not be deemed present for the purpose of determining whether a quorum exists.
Under the rules of the New York Stock Exchange, which regulates stock brokers, Proposal 2, the ratification of the selection of Deloitte & Touche LLP as the Company’s independent registered public accounting firm, is considered a routine matter, and your brokerage firm or other nominee will be entitled to vote your shares in their discretion on this proposal even if you do not provide voting instructions to your broker or other nominee. However, Proposals 1, and 3 are not considered routine matters, and brokers will not be permitted to vote on these matters if beneficial owners fail to provide voting instructions. The uninstructed shares that cannot be voted by brokers on non-routine matters are commonly referred to as “broker non-votes.”
Abstentions and broker “non-votes” (assuming a quorum is present) will have no effect on Proposals 2, and 3. Votes withheld and broker “non-votes” with respect to the election of any nominee for director will not be considered in determining whether such nominee has received the affirmative vote of a plurality of the votes cast; however, such votes will be considered to have a similar effect as a vote against those director nominees under our majority voting policy.
How can I attend the 2024 Annual Meeting? The 2024 Annual Meeting will be held virtually over the internet. You will be able to participate in the virtual 2024 Annual Meeting and vote your shares electronically by visiting https://www.virtualshareholdermeeting.com/EFSC2024 and entering your sixteen-digit control number located on your proxy card. The virtual 2024 Annual Meeting will begin promptly at 5:00 p.m. Central Time. We encourage you to access the meeting prior to the start time. Online check-in will begin at 4:45 p.m. Central Time, and you should allow ample time for logging in. You will have the same rights and opportunities that you would be afforded by an in-person meeting. Registered shareholders who login with their control number will be afforded an opportunity to vote their shares during the meeting and comment on proposals during the meeting. Representatives of the Company will be available to respond to relevant comments and questions.
What if I cannot locate my control number? You must have your control number to vote your shares. The sixteen-digit control number is located on your proxy card. If you are unable to locate your control number or proxy card, please note the following:
•If you shares are held in “street name” (i.e. your shares are held in a stock brokerage account or by a bank), you will need to contact your broker or financial institution directly and ask for their proxy department to obtain the necessary information.
3

•If you are a registered shareholder (i.e. the shares are registered in your name with our stock transfer agent), please send an email to the Company’s Investor Relations department, investorrelations@enterprisebank.com, and provide information regarding the name of the person holding the shares and the amount of shares owned.
Who pays for this proxy solicitation? The Company will pay the entire cost of preparing, assembling, printing, mailing and distributing these proxy materials. In addition to solicitation by mail, proxies may be solicited in person or by telephone or by other means by the Company’s directors, officers or employees, who will not receive any additional compensation for solicitation activities. The Company has engaged Broadridge Financial Solutions, Inc., for a fee to be determined, to assist in the distribution and tabulation of proxies. The Company will also reimburse brokerage firms and other nominees, custodians and fiduciaries for costs incurred by mailing proxy materials to the beneficial owners of common stock as of the Record Date.

The date of this Proxy Statement is March 19, 2024.

PROPOSAL 1. ELECTION OF DIRECTORS

The Board, upon recommendation of its Nominating and Governance Committee, has nominated for election the 14 persons named below, each to hold office until the next annual meeting of shareholders or until their successors are elected and have qualified. It is intended that proxies solicited will be voted for such nominees. There is no cumulative voting for our directors. The Board believes that each nominee named below will be able to serve, but should any nominee be unable to serve as a director, the persons named in the proxies have advised that they will vote for the election of such substitute nominee as the Board may propose.
Under our mandatory retirement policy, a director is generally required to retire at the next annual meeting of shareholders after the later of: reaching age 72 or the fourth anniversary of the director’s initial election to the Board, and may not stand for election or re-election thereafter. However, a director need not retire and may stand for re-election if the Board, by unanimous vote, approves a waiver for such director, provided that any such waiver must be renewed annually and no waiver will be made or renewed for any director after reaching the age of 75.
The following biographical information is furnished with respect to each member of the Board, whom also serve as directors and officers (with respect to James B. Lally) of one or more of the Company’s subsidiaries, including Enterprise Bank & Trust (the “Bank” or “EB&T”).

Recommendation of the Board of Directors
THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR EACH OF THE
NOMINEES LISTED ABOVE FOR ELECTION AS DIRECTORS OF THE COMPANY.

BOARD AND COMMITTEE INFORMATION

The Board has determined that having an independent director serve as Chairperson of the Board is in the best interest of shareholders at this time. The structure ensures a greater role for the independent directors in the oversight of the Company and active participation of the independent directors in setting agendas and establishing priorities and procedures for the work of the Board. Director DeCola is the current Chairperson of the Board and has held that position since May 2023.
The Board is actively involved in oversight of risks that could affect the Company. This oversight is conducted primarily through committees of the Board, as disclosed in the descriptions of each of the committees below and in the charters of each of the committees; however, the full Board has retained responsibility for general oversight of risks. The Board satisfies this responsibility through reports by each committee chair regarding the committee’s considerations and actions, as well as through regular reports directly from officers responsible for oversight of particular risks within the Company.
All committee members are appointed by the Board on recommendation of the Nominating and Governance Committee. In addition, the Board has established membership standards for each committee which requires that a certain number of committee members must be “independent directors,” as that term is defined in Rule 5605(a)(2) of the Nasdaq rules.
The Board met seven times in 2023. All incumbent directors attended at least 75% of all meetings of the full Board and of those committees on which they served in 2023. The Company’s Board periodically held executive sessions of the members of the Board who met the then current standards of independence. Executive sessions of the Board were presided over by the Chairperson of the Board.
While there is no formal policy concerning director attendance at the annual meeting, all members of the Board are encouraged to attend if reasonably able to do so. Fourteen out of sixteen of the then serving members of the Board attended the 2023 Annual Meeting of Shareholders (as noted, Messrs. Eulich and Hui did not stand for re-election and retired from the Board immediately following the Annual Meeting of Shareholders).

DIVERSITY
The Company and the Board strongly believe diversity is critical to the Company’s success and creating long-term value for our shareholders. We believe that a board consisting of individual directors with diverse backgrounds ensures broader representation and inspires deeper commitment to management, employees and the communities we serve. While not specific to a particular policy, the Company’s Board prioritizes diversity in gender, demographic background, and professional experience when considering candidates for director as part of its commitment to diversity. At present, 43% of our Board is diverse from a female or underrepresented minorities perspective based on self-identification. In addition, the Company is committed to a culture of inclusiveness, equality and diversity at all levels of the Company’s workforce, offering a supportive and understanding environment designed to assist all individuals in realizing their maximum potential, regardless of their differences. Our goal is to ensure that, in carrying out our activities, we promote equality of opportunity and good relations between people of diverse backgrounds, and avoid unlawful discrimination. As of December 31, 2023, approximately 38% of our executive officers, and approximately 55% of our leadership team were diverse from a female or underrepresented minorities perspective based on self-identification.

In 2023, non-employee directors received a $110,000 annual retainer, except for Mr. DeCola who received a $180,000 retainer for his service as Chairperson of the Board and Executive Committee. Annual retainers are paid in July of each year for the upcoming 12-month period. For committee service, the Chairpersons received an additional retainer as follows: Audit and Risk Committees - $18,000 for each committee, and Compensation and Nominating and Governance Committees - $15,000 for each committee. Non-Chairperson committee members received a retainer for Audit and Risk Committees of $7,500 for each committee and for Compensation and Nominating and Governance Committees of $5,000 for each committee. For January 2023 - June 2023, directors received $1,250 per board meeting attended and non-chairperson committee members received $1,000 per committee meeting attended.
Non-employee directors receive a minimum of $60,000 of their retainer in shares of EFSC common stock unless a non-employee director elects to receive 100% of such director’s retainer fees in shares. Any election to receive 100% of the retainer fees in shares will remain in effect until revoked by the non-employee director. The number of shares received by the non-employee director depends on the fair market value of the Company’s common stock on the date of grant. Shares are granted on the date that the cash retainer or meeting fees would otherwise have been paid. Shares are fully vested upon grant.
EXECUTIVE COMMITTEE
The Executive Committee is empowered to act on behalf of, and to exercise the powers of, the full Board in the management of the business and affairs of the Company when the full Board is not in session, except to the extent limited by applicable Delaware law. The charter for the Executive Committee may be found in the investor relations section of the Company’s website at www.enterprisebank.com. All actions by the Executive Committee are reported at the next regular Board meeting. The Executive Committee met one time in 2023.
All members of the Executive Committee meet the Nasdaq independence standards. In 2023, Directors DeCola (Committee Chairperson), Guest, Holmes, and Van Trease served on the committee for the full year. Director John Eulich (from January 2023 through his retirement as of the annual meeting in May 2023) served on the committee for a portion of the year. Director Kent was appointed to serve on the committee in May 2023.
10

AUDIT COMMITTEE
The Audit Committee oversees the Company’s financial reporting process on behalf of the Board by reviewing all audit processes and fees, the financial information provided to the shareholders and the Company’s systems of internal financial controls. The Audit Committee has the authority and responsibility to select and evaluate and, where appropriate, replace the Company’s independent registered public accounting firm.
The Audit Committee is responsible for oversight of Company risks relating to accounting matters, financial reporting, legal and regulatory compliance and the Company’s anonymous “whistleblower” reporting system. To satisfy these oversight responsibilities, the committee separately meets regularly with the Company’s Chief Financial Officer, its Chief Risk Officer, its Director of Internal Audit, the Company’s independent registered public accounting firm, and management. The Audit Committee Chairperson periodically meets between formal committee meetings with the Company’s Chief Financial Officer, its Chief Risk Officer, its Director of Internal Audit, and the Company’s independent registered public accounting firm. The committee also receives regular reports regarding issues such as the status and findings of audits being conducted by the internal auditors and the independent registered public accounting firm, the status of material litigation, accounting changes that could affect the Company’s financial statements and proposed audit adjustments.
All members of the Audit Committee meet the Nasdaq independence standards and meet the additional requirements applicable to Audit Committee members. In 2023, the Audit Committee consisted of Directors Kent (Committee Chairperson), Havel, Rodrigues, Schmitz, and Van Trease for the full year. Director Andrich was appointed to serve on the committee in February 2023. The Audit Committee met five times in 2023.
The Board has determined that Audit Committee members Kent, Andrich, Havel, Schmitz, and Van Trease satisfy the requirements of an “audit committee financial expert” as defined in Item 407(d)(5) of Regulation S-K and satisfy the definition of “financially sophisticated” under Nasdaq Rule 5605(c).
The Company’s Board has determined that none of the Directors on the Audit Committee have a relationship with the Company or the Bank that would interfere with the exercise of independent judgment in carrying out their responsibilities as director. None of them is, nor have they been for the past three years, an employee of the Company or the Bank, and none of their immediate family members is, nor have they been for the past three years, an executive officer of the Company or the Bank.
As noted in the Audit Committee charter, which is available in the investor relations section of the Company’s website at www.enterprisebank.com, the Company’s management is responsible for preparing the Company’s financial statements. The Company’s independent registered public accounting firm is responsible for auditing the financial statements. The activities of the Audit Committee are in no way designed to supersede or alter those traditional responsibilities. The Audit Committee’s role does not provide any special assurances with regard to the Company’s financial statements, nor does it involve a professional evaluation of quality of audits performed by the independent registered public accounting firm. The Audit Committee reassesses the adequacy of the charter on an annual basis.
The Audit Committee has considered whether the provision by the Company’s independent registered public accounting firm of the services covered by the audit fees is compatible with maintaining its independence and has concluded that it is compatible. The Audit Committee is responsible for pre-approving all auditing services and permitted non-auditing services to be performed by the Company’s independent registered public accounting firm. The Chairperson of the Audit Committee has authority to approve in advance all audit or non-audit services to be performed by the independent registered public accounting firm, but must report any such approval to the full Audit Committee at the next regularly scheduled meeting.
The Report of the Audit Committee appears on page 44 of this Proxy Statement.
NOMINATING AND GOVERNANCE COMMITTEE
The Nominating and Governance Committee assists the Board in identifying and recommending qualified director nominees for election at the 2024 Annual Meeting. The charter for the Nominating and Governance Committee may be found in the investor relations section of the Company’s website at www.enterprisebank.com. The committee recommends membership on Board committees, reviews and assesses the Company’s governance guidelines, policies and practices, and oversees an annual Board self-evaluation.
All members of the Nominating and Governance Committee meet the Nasdaq independence standards. In 2023, the Nominating and Governance Committee consisted of Directors Van Trease (Committee Chairperson), DeCola, Guest, Holmes, and Schmitz
11

for the full year. Directors Manjarrez and Young were appointed to serve on the committee in February 2023. The committee met four times in 2023.
The Nominating and Governance Committee may consider candidates for Board membership coming to its attention through current Board members, search firms, shareholders and other persons. Suggestions for nominees from shareholders are evaluated in the same manner as other nominees. Any shareholder nomination must be submitted in writing to the Company’s Corporate Secretary at: Enterprise Financial Services Corp, 150 North Meramec Ave., Clayton, Missouri 63105, and should include the shareholder’s name, address and the number of the Company’s shares owned by the shareholder, along with the nominee’s name and qualifications in accordance with the procedures set forth in our By-Laws. No shareholder nominations for director were received for the 2024 Annual Meeting.
The Nominating and Governance Committee has the flexibility to consider various factors it deems appropriate in identifying and evaluating potential candidates for director nominees as there is no strict set of qualifications that must be satisfied before a candidate may be considered. These factors may include education, diversity, experience with business and other organizations comparable with EFSC, the interplay of the candidate’s experience with that of other members of the Board, and the extent to which the candidate would be a desirable addition to the Board and to any of the committees of the Board. The Nominating and Governance Committee will evaluate nominees for directors submitted by shareholders in the same manner in which it evaluates other director nominees.
Shareholders may communicate directly to the Board, including individual directors and our presiding Chairperson, by sending a letter to the Board at the following address: Enterprise Financial Services Corp Board of Directors, 150 North Meramec Ave., Clayton, Missouri 63105. All communications directed to the Board will be received and processed by the Company’s Corporate Secretary and will be transmitted to the Chairperson of the Nominating and Governance Committee without any editing or screening.
COMPENSATION COMMITTEE
In 2023, the Compensation Committee consisted of Directors Holmes (Committee Chairperson), DeCola, Holmes, Kent, and Van Trease for the full year.

The Compensation Committee met five times in 2023. The Compensation Committee is comprised solely of non-employee directors, all of whom the Board has determined are independent pursuant to the Nasdaq rules. The responsibilities of the Compensation Committee are set forth in its charter, which is available in the investor relations section of the Company’s website at www.enterprisebank.com, and includes the responsibility for establishing, implementing and continually monitoring compliance with the Company’s compensation philosophy. During 2023, no member was an executive officer of another entity on whose compensation committee or board of directors an executive officer of the Company served.
The Compensation Committee is responsible for risks relating to employment policies and the Company’s compensation and benefits program. To assist it in satisfying these oversight responsibilities, the Compensation Committee has retained its own compensation consultant and meets regularly with management and with outside counsel to understand the financial, human resources and shareholder implications of compensation decisions being made. For additional information regarding our engagement of a compensation consultant, see “Executive Compensation - Overview of the Compensation Process.” The Compensation Committee is also responsible for furthering the advancement of the Company’s goals related to environmental, health and safety, corporate social responsibility, sustainability and other public policy matters (collectively, “ESG”) (as they continue to evolve) through the Company’s compensation arrangements, policies and decisions, to the extent the Compensation Committee deems necessary to do so.
The Compensation Committee Report appears on page 24 of this Proxy Statement.
RISK COMMITTEE
The Risk Committee assists the Board in carrying out its responsibilities with respect to the comprehensive oversight of the types and levels of risk being incurred by the organization, and the effectiveness of the methods used to identify, monitor, manage, and report those risks. The charter for the Risk Committee may be found in the investor relations section of the Company’s website at www.enterprisebank.com.
The responsibilities of the Risk Committee are to review the Company’s Risk Appetite Statement and Risk Tolerances, evaluate the Company’s risk priorities, and to monitor and evaluate the Company’s risk profile as determined by management.

EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION AND ANALYSIS
This section provides information regarding our compensation programs for our named executive officers (“Named Executive Officers” or “NEOs”) for 2023, including our overall philosophy, components of compensation that we provide, and the objectives and intended incentives of our programs. Our Named Executive Officers for 2023 were as follows:

Name | Title
James B. Lally | President and Chief Executive Officer, Enterprise Financial Services Corp, Chairman and Chief Executive Officer, Enterprise Bank & Trust
Keene S. Turner | Senior Executive Vice President and Chief Financial Officer, Enterprise Financial Services Corp and Enterprise Bank & Trust

Douglas N. Bauche | Senior Executive Vice President and Chief Credit Officer, Enterprise Financial Services Corp and Enterprise Bank & Trust
Mark G. Ponder | Senior Executive Vice President and Chief Administrative Officer, Enterprise Financial Services Corp and Enterprise Bank & Trust.

Principles. Our compensation philosophy is to provide competitive compensation that rewards executives for performance and management of risk. We develop and administer compensation programs consistent with the following principles:
•Compensation will include a substantial performance-based component which is:
◦based on clearly defined goals;
◦aligned with measurable business results, appropriate risk management and increase in shareholder value; and
◦linked to successful implementation of our business plan.
•Compensation is designed to attract, motivate and retain top talent.
•Compensation will be fair and market competitive.

Fiscal Year 2023. The financial market and the banking industry were volatile in 2023. Early in the year, three large banks failed, representing three of the four largest bank failures since 1934. These failures contributed to a 2% loss in commercial bank deposits during the year as depositors moved funds for safety and higher yields. The tightening of liquidity within the bank system increased the cost of funds for the industry. Inflation continued to be high, resulting in the Federal Reserve increasing the target federal funds rate 100 basis points in 2023. This followed a 425 basis point increase in 2022. The target rate increased from a range of 425-450 basis points at the end of 2022, to a range of 525-550 basis points at the end of 2023. Higher interest rates typically benefit banks with an asset-sensitive balance sheet, such as the Company, by increasing net interest income and the net interest margin. However, increased deposit competition in the industry resulted in higher cost funding that accelerated throughout the year.
The Company had strong financial performance in 2023, including:
•Record operating revenue (net interest income and noninterest income) of $631 million.
•Net income and diluted earnings per share of $194 million and $5.07, respectively.
•Increased tangible book value per share 2 18% to $33.85.
•Achieved a Pre-Provision Net Revenue “PPNR” return on average assets 2 of 2.1%.
•Achieved a return on average tangible common equity 2 of 16.4%.
•Increased total loans and deposits by 12% each.
•Strengthened the liquidity profile of the balance sheet.
•Maintained relatively strong asset quality, with a ratio of nonperforming assets to total assets of 0.34%.
•Common shareholder dividends increased 11% in 2023, the ninth consecutive year dividends have been increased.
2 A non-GAAP measure. Refer to discussion and reconciliation of this measure in Appendix A.
The STIP payouts were 105%-109% of the target opportunity for the Named Executive Officers. The LTIP performance cycle ending in 2023 resulted in a payout equal to 169% of target shares. The payout for the three-year LTIP cycle ending in 2023 included a maximum payout of 200% of target on the performance award based on the PPNR goal and a payout of 138% of target on the relative total shareholder return (“TSR”) portion of the award. Overall, we believe our compensation program has been designed and implemented consistent with our principles and that our executives realized compensation has been aligned with the Company’s performance.
Further, just as our business is adapting for future success, so too is our compensation program. Our compensation program is continually reviewed and will be adapted as needed to support progress towards achievement of goals.
Shareholder Engagement. Our shareholders have consistently approved our executive compensation program by high margins in every shareholder advisory vote on executive compensation that we have conducted. Last year, shareholders approved our
16

executive compensation program with 80% of voted ballots cast in favor of our program. These votes are advisory and not binding upon the Compensation Committee of the Board of Directors (the “Committee”); however, the Committee takes the outcome of the votes into consideration in making executive compensation decisions.
The Company maintains an active dialogue with many of its institutional shareholders. In this process, the Company discusses matters ranging from financial results, executive compensation, and corporate governance. This dialogue assists the Company in developing its approach to future compensation as well as addressing certain aspects within its annual ESG report.
Allocation of Compensation Components in 2023. Below is a summary of the allocation of compensation for our Named Executive Officers in 2023:

Name | Base Salary (1) |  | Bonus (2) |  | Short-term Annual Incentive Compensation (3) |  | Long-term Incentive Compensation (4) |  | NEO Perquisites (5) |  | Total

Overview of the Compensation Process
The Committee administers the Company’s executive compensation programs under the authority of its charter approved by the Board. The Committee has responsibility for establishing, implementing and monitoring compliance with the Company’s compensation philosophy.
The Committee has overall responsibility relating to compensation for the officers and other employees of the company. Other than with respect to Named Executive Officers and other executive officers, the Committee delegates certain of those functions to management. In the case of Named Executive Officers and other executive officers, the Committee establishes and reviews base salaries, short-term incentives, and long-term incentives, including measurement metrics and goals. With respect to executives below this level, the Committee reviews management’s recommendations with respect to these matters. In the case of our non-executive employees, the Committee reviews, approves, and monitors overall compensation practices. The Committee retains oversight over compensation programs that are delegated to management, including evaluating compensation structure and practices to determine that they do not encourage inappropriate risk to the Company.
Performance Reviews. The Executive Committee is responsible for overseeing and delivering the annual performance review of the Chief Executive Officer. This review is based on the financial performance of the Company, the change in shareholder value, growth in the human capital of the organization, effective succession planning, leading the organization’s culture, the Company’s overall management of risk, and development and execution of our strategy. The Executive Committee meets and reviews the overall assessment of the Chief Executive Officer without the Chief Executive Officer being present. The Executive Committee reports the Chief Executive Officer’s rating to the Compensation Committee.
17

Our Chief Executive Officer conducts and approves performance evaluations for the other Named Executive Officers and shares the evaluations with the Compensation Committee. A Compensation Committee member presents the Committee’s decisions for compensation of each Named Executive Officer to the full Board.
Compensation Consultant. The Committee has the authority to directly engage the services of a Compensation consultant or other advisors. Willis Towers Watson (“WTW”) was retained by the Committee to serve as the Company’s independent compensation consultant for 2023. In connection with the 2023 retention, the Committee assessed WTW’s independence, considering the factors set forth in Nasdaq Rule 5605(d)(3) regarding compensation advisor independence, consistent with the Committee’s Charter. The Committee did not find any conflict of interest with respect to WTW in 2023.
WTW’s work for the Committee in 2023 included: (i) presentation of market competitive data for purposes of the Committee’s analysis of the Company’s compensation for executive officers; (ii) providing business and technical advice on executive compensation matters, including short-term and long-term incentive compensation and recent trends; (iii) pay for performance and shareholder meeting analysis; (iv) review of nonemployee director compensation; (v) an assessment of the Company’s peer group used for compensation purposes; and (vi) updates on regulatory changes.
Comparisons to Peer Group. The Committee uses competitive data to compare its compensation levels to a group of peer companies with respect to the following elements of compensation for Named Executive Officers:
•Base salary;
•Short-term annual incentives;
•Equity compensation elements such as performance contingent grants of stock; and
•Other elements that to date have been reported publicly under SEC rules.
The Committee selects the peer group with the advice of the Company’s compensation consultant and input from management.
The peer group companies were selected to reflect financial institutions of comparable asset size to the Company with operations that are comparable to the Company’s lines of business. The Committee believes that these component companies represent institutions that compete for the Company’s talent pool. The Committee does not set rigid benchmarks for compensation of Named Executive Officers. The Committee’s objective is to offer total target compensation for Named Executive Officers that is competitive with the Company’s peers considering the relative performance of the executive and the Company. The Committee evaluates the competitiveness of the Company’s executive compensation by comparisons to the peer group to be competitive and enhance retention.
In 2023, our peer group consisted of the following companies:

1st Source Corporation | Heartland Financial USA, Inc.
Atlantic Union Bankshares | Hope Bancorp, Inc.
BancFirst Corporation | Independent Bank Group, Inc.
Brookline Bancorp, Inc. | Origin Bancorp, Inc.
Eagle Bancorp, Inc. | Park National Corporation
First Busey Corporation | Renasant Corporation
First Commonwealth Financial Corp | ServisFirst Bancshares, Inc.
First Financial Bancorp | Simmons First National Corporation
First Financial Bankshares, Inc. | Trustmark Corporation
First Merchants Corporation | Veritex Holdings, Inc.

Setting Compensation. The Committee considers the results of performance evaluations, peer group comparisons, and a review of the Company’s goals and objectives. Based on this review, the Committee approves, and reports to the Board its decisions regarding the base salary, STIP targets and LTIP awards for our Named Executive Officers for the current year, as well as short-term incentive compensation earned for the prior year.
18

Compensation Components
Our executive compensation consists primarily of these three components:
•Base salary;
•Short-term annual incentive awards; and
•Long-term equity incentive compensation.
As is customary in our industry, we also provide modest levels of perquisites, described later, to our Named Executive Officers and participation in other benefit programs that are generally available to the general associate population (e.g., health care, disability, life insurance, an employee stock purchase plan and a defined contribution plan). The “Summary Compensation Table” on page 29 provides additional information on these perquisites and benefits.
The Committee maintains a flexible policy for the allocation of compensation components. Allocations of compensation among the various components are intended to align compensation with achievement of short- and long-term performance goals and appropriate risk management while remaining competitive in comparison to the Company’s peer group.
Base Salaries. Base salaries recognize and compensate for competencies, experience, and knowledge that we believe our Named Executive Officers must possess. The Committee also considers external market data to assess the competitiveness of our base salary levels.
The Committee evaluated the NEOs’ total compensation and implemented base salary increases for 2023. The increases were based on: the Company’s financial and operating performance; the depth and breadth of the Company’s operations; market and competitive forces; and the NEOs’ leadership examples. Based on these factors, in 2023, the Committee approved increases in base salaries for the Company’s Named Executive Officers as follows:

Named Executive Officer |  | Base Salary Increase
James B. Lally |  | 9.4%
Keene S. Turner |  | 17.6%
Scott R. Goodman |  | 11.5%
Douglas N. Bauche |  | 13.3%
Mark G. Ponder |  | 13.9%

The increases align each NEO’s base compensation to a band of total compensation similar to peers. In making its determinations regarding base compensation and STIP, the Committee generally attempts to pay NEOs at approximately the 50th percentile for target levels of performance. The Committee generally prefers that LTIP opportunities are targeted in a manner such that total direct compensation will fall between the 50th and 75th percentile of the Company’s peers at target level of performance in order to retain and incent high quality executives in a manner consistent with shareholder interests.
Short-Term Incentive Plan. Our STIP is designed to align compensation with the Company’s and an executive’s performance in a given year. The program sets a threshold, target and exceptional level of short-term incentive awards that an NEO is eligible to earn. In the first quarter of each year, our CEO, with the input of other members of management where appropriate, presents proposed performance metrics and goals to the Committee for review and approval. The relative importance of each goal in comparison to all goals is determined, and the resulting weightings determine potential incentive payments for each goal. The Committee also references external market data to determine appropriate target levels of payments.
Each NEO’s 2023 target STIP opportunity was as follows:

Named Executive Officer |  | STIP Target as a % of Base Salary
James B. Lally |  | 80%
Keene S. Turner |  | 55%
Scott R. Goodman |  | 50%
Douglas N. Bauche |  | 45%
Mark G. Ponder |  | 45%

19

For performance below threshold level of any goal, there is no payment with respect to that goal. Payout for performance between the threshold, target and exceptional levels is determined using straight-line interpolation. The program provides the Committee discretion to make awards subject to a maximum.
The Company’s 2023 STIP utilized five metrics and goals, consistent with our strategic plan, that were applied across all NEOs and other members of senior management. The Committee believes the metrics and goals align the interests of NEOs and other members of senior management’s incentives with the interests of the Company’s shareholders and encourage superior performance in critical areas, such as efficient operations, profitability, prudent growth and effective risk management.
Following is a summary table of the STIP performance metrics and goals, and the actual results of the Company for 2023 as modified as described below the table:

($ in thousands, except per share data) |  | % Weight At Target |  | Threshold |  | Target |  | Exceptional |  | Actual (1)
EPS |  | 40% |  | $ | 4.51 |  |  | $ | 5.35 |  |  | $ | 5.66 |  |  | $ | 5.12 |
Loan growth |  | 15% |  | $ | 195,000 |  |  | $ | 584,000 |  |  | $ | 775,000 |  |  | $ | 1,149,403 |
ROATCE |  | 20% |  | 14.70 | % |  | 17.40 | % |  | 18.40 | % |  | 16.40 | %
Ratio of nonperforming assets to total assets |  | 10% |  | 1.00 | % |  | 0.50 | % |  | 0.40 | % |  | 0.34 | %

(1) The EPS and ROATCE results were adjusted to exclude the impact of the $2.4 million FDIC special assessment caused by the bank failures in the first half of 2023 not anticipated at the time targets were established. In addition, for the reasons described in more detail in the paragraphs discussing the table below, the Committee added discretionary bonuses to these results in the amounts set forth in the Discretionary Column of that table.
In addition to the above four Company-based metrics, 15% of each NEO’s STIP award is based on his or her leadership rating. The “Leadership Rating” goal consists of a rating of between one and four. The threshold level is a rating of two, the target level is a rating of three and the exceptional level is a rating of four. The Leadership Rating measures an NEO’s subjective performance during the past fiscal year and is based on expectations set for the leader at the beginning of the fiscal year. The Committee evaluates the leadership for each NEO as part of the annual performance review process.
Based on the achievements listed on page 16, for 2023, the Leadership Rating was 3.5 for Messrs. Lally, Goodman and Bauche and a Leadership Rating of 4 was assigned to Messrs. Turner and Ponder.
The 2023 STIP payouts for each NEO are set forth below:

Name |  |  |  | Threshold |  | Target |  | Exceptional |  | Actual |  | Discretionary
James B. Lally |  | Award Value |  | $ | 350,000 |  |  | $ | 700,000 |  |  | $ | 1,050,000 |  |  | $ | 736,891 |  |  | $ | 150,000 |
Keene S. Turner |  | Award Value |  | 165,000 |  |  | 330,000 |  |  | 495,000 |  |  | 359,767 |  |  | 75,000 |
Scott R. Goodman |  | Award Value |  | 121,250 |  |  | 242,500 |  |  | 363,750 |  |  | 255,281 |  |  | 60,000 |
Douglas N. Bauche |  | Award Value |  | 95,625 |  |  | 191,250 |  |  | 286,875 |  |  | 201,329 |  |  | 50,000 |
Mark G. Ponder |  | Award Value |  | 92,250 |  |  | 184,500 |  |  | 276,750 |  |  | 201,143 |  |  | 40,000 |

In 2023, the EPS and ROATCE results were between threshold and target. The Compensation Committee considered how the STIP goals were set in early 2023, prior to the bank failures that occurred and the resulting disruption in the market. Consideration was given to how well the Company’s actual performance compared to the peer group and the performance of the NEOs throughout a tumultuous year. Based on these factors, the Compensation Committee awarded a discretionary bonus payment to each of the NEOs that is disclosed in the Bonus column of the “Summary Compensation Table” and in the Discretionary column in the table above. In addition, the EPS and ROATCE targets were adjusted to exclude the impact of the $2.4 million FDIC special assessment caused by the bank failures in the first half of 2023 that were not anticipated at the time the STIP targets were established.

Long-Term Incentive Plan. Our objectives for the LTIP for our Named Executive Officers include:
•Aligning incentives with increases in shareholder value;
•Attracting and retaining talented executives;
•Encouraging appropriate long-term risk management practices; and
•Providing a clear line of sight towards long-term success.
Each NEO’s 2023 target LTIP opportunity was as follows:

Named Executive Officer |  | LTIP Target as a % of Base Salary
James B. Lally |  | 175%
Keene S. Turner |  | 120%
Scott R. Goodman |  | 100%
Douglas N. Bauche |  | 90%
Mark G. Ponder |  | 90%

The Committee also considers external market data to determine competitive dollar levels of long-term incentive compensation and an appropriate mix between base salary, annual incentive, and long-term incentives.
Grants under the LTIP include performance and time-based restricted stock units and non-qualified stock options. Performance based units vest upon achievement of performance goals during a three-year period. Time-based units and options vest in full at the end of the three-year period. The Committee has allocated a significant portion of NEO stock awards to include performance criteria. The Committee believes that stock awards with performance conditions provide more competitive equity compensation to executives and greater alignment with shareholders. In addition, granting performance-based awards with overlapping three-year performance periods incentivizes and rewards our executives for long-term Company success.
Each year management makes a recommendation to the Committee for grants to Named Executive Officers other than the CEO. The Committee reviews this proposal in light of the Committee’s goals and philosophies for incentive compensation, the Company’s strategy and long-term goals, and marketplace information, including market data provided by compensation consultants. The Committee makes the final determination of the amount and structure of grants to each Named Executive Officer.
Long-Term Incentive Plan Awards for 2021-2023 Performance Period
Grants for the performance period provided for the possibility of awards at a threshold, target and exceptional level based on the Company’s performance against two financial goals: (1) TSR, and (2) PPNR. In addition, grants for Named Executive Officers have a weighting of 40% based on continued service through the end of the performance periods. The 40% based on continued service includes 25% in stock options and 15% in time-based restricted stock units.
In February 2021, the Committee made the decision to replace EPS with PPNR for the 2021-2023 LTIP cycle. The Committee believed that PPNR was the better profitability measure in the pandemic environment, and considered the expected volatility associated with the adoption of the current expected credit losses methodology (CECL).
The performance goals and actual outcomes for the period are set forth below:

2021 - 2023 Performance Period
Goal |  | Weight |  | Threshold |  | Target |  | Exceptional |  | Actual
TSR |  | 30% |  | 40 th percentile |  | 60 th percentile |  | 80 th percentile |  | 68th percentile
PPNR ($ in thousands) |  | 30% |  | $500,471 |  | $534,920 |  | $555,797 |  | $642,468
Continued Service |  | 40% |  | N/A |  | N/A |  | N/A |  | N/A
|  | 100% |  |  |  |  |  |  |  |

In determining actual performance against the cumulative PPNR goal, the Company excluded the merger-related positive impact from the Company’s acquisition of First Choice. The Committee believes that this adjustment is appropriate for two

reasons: (i) this adjustment creates a better “apples to apples” comparison between the Company and our peer companies, most of which did not consummate an acquisition in 2021; and (ii) the effect of this merger was not contemplated at the time that the original goals were set three years ago. The cumulative effect of this adjustment was a reduction to reported PPNR of $45.8 million. This adjustment did not impact the TSR calculation.
For each goal, achieving threshold performance pays at 25% of target value and achieving exceptional performance pays at 200% of target value. For performance below threshold level of any goal, there is no payment with respect to that goal. Payout for performance falling between the threshold, target and exceptional levels is determined using straight-line interpolation. Based on the Company’s actual performance during the 2021-2023 performance period, the Company awarded shares for the PPNR goal at the maximum level (200% of target) and awarded shares between target and exceptional for the TSR goal (138% of target). This resulted in performance awards at 169% of the aggregate target level.
Our Named Executive Officers received the following respective awards under the LTIP, including time-based service awards, for the 2021-2023 performance period:

2021-2023 LTIP Award
|  | Shares of Common Stock |  | Stock Options
Named Executive Officer |  | Performance Award | Service Award | Total |  | Service Award
James B. Lally |  | 22,612 | 3,345 | 25,957 |  | 17,637
Keene S. Turner |  | 11,593 | 1,715 | 13,308 |  | 9,042
Scott R. Goodman |  | 8,051 | 1,191 | 9,242 |  | 6,280
Douglas N. Bauche |  | 6,064 | 897 | 6,961 |  | 4,730
Mark G. Ponder |  | 5,797 | 857 | 6,654 |  | 4,521

The shares awarded were in the form of common stock.
Long-Term Incentive Open Grants for 2022-2024 and 2023-2025 Performance Periods
Long-Term Incentive Plan grants are open with respect to the 2022-2024 and 2023-2025 performance periods. Grants for Named Executive Officers are reflected in the Summary Compensation Table in the year of grant on page 29 and the Grants of Plan-Based Awards table on page 35. The LTIP grants relating to the 2022-2024 performance periods vest 30% based on TSR return goals, 30% based on EPS goals, and 40% based on continued service through the end of the performance period. LTIP grants for the 2023-2025 performance periods are the same as the 2022-2024 cycle. For both cycles, the 40% based on continued service includes 25% in stock options and 15% in time-based restricted stock units.
For each performance-based goal, achieving threshold performance pays at 25% of target value and achieving exceptional performance pays at 200% of target value. For performance below threshold level of any goal, there is no payment with respect to that goal. Payout for performance falling between the threshold, target and exceptional levels is determined using straight-line interpolation. The open grants to Named Executive Officers under these LTIP grants will be paid in the form of immediately vested shares of common stock or stock options, as applicable.
Named Executive Officer Perquisites. We provide perquisites and other personal benefits to Named Executive Officers that we believe are reasonable and consistent with our overall compensation program. See the “All Other Compensation - Supplemental Table” on page 30 for more information on these items.
Retirement Plans. We expect executives to plan for and fund their own retirement through a defined contribution 401(k) plan that is generally available to most of the employees of the Company and a Deferred Compensation Plan that permits certain executives to defer a limited portion of salary and incentive payouts into any of several hypothetical investment alternatives. The Company has historically provided a Company match to the 401(k) plan. There are no Company contributions to the Deferred Compensation Plan. We do not maintain defined benefit retirement or supplemental executive retirement plans or provide for post-retirement benefits.
Change in Control Severance Benefits
We have entered into employment agreements with certain of our Named Executive Officers granting them “double-trigger” change in control severance benefits (i.e., the benefit is triggered if the executive experiences a qualifying termination upon a change in control of the Company), as more fully described under the heading “Executive Employment Agreements” on page 25. The Committee believes these employment agreements providing double-trigger change in control severance benefits serve the best interests of the Company and its shareholders by ensuring that, in considering any proposed change in control, the Named Executive Officers would be able to advise the Board objectively about the transaction, without being unduly influenced
22

by personal concerns such as the loss of employment following a change in control. These arrangements are also intended to promote stability and continuity of executive management. Information on applicable payments under such employment agreements for Named Executive Officers is contained under the heading “Executive Employment Agreements” on page 25 and “Potential Payments Upon Termination or Change in Control” on page 38.
Sections 280G and 4999
Our Named Executive Officers are not entitled to any tax gross-up in the event they are subject to taxes under Sections 280G or 4999 of the Code, in connection with a change in control.
Section 162(m) of the Internal Revenue Code - Compensation Deductibility Limits
Code Section 162(m) generally limits the Company’s ability to deduct compensation in excess of $1 million to the Company’s chief executive officer, chief financial officer, three other highest-compensated officers and any officer covered in a prior tax year. The Committee considers the availability of a tax-deduction on executive compensation as a relevant consideration when setting the NEO’s overall compensation package, subject to the primary goals of attracting, retaining and rewarding the executive officers.
Clawback Policy
The Company has adopted a clawback policy permitting the Committee to recover incentive compensation paid to covered employees (including at a minimum, executive officers identified by the Board pursuant to 17 CFR § 229.401(b)) based on materially inaccurate financial information requiring a restatement of previously issued financial statements. A copy of the clawback policy is available on the Company’s website at www.enterprisebank.com.
Stock Ownership Guidelines
The Company’s stock ownership guidelines provide that non-employee directors and different levels of executives are expected to own a specific amount of our common stock within the later of five years of adopting the program or five years after the date the executive becomes a Named Executive Officer or director as applicable. Named Executive Officers and non-employee directors are expected to make continuing progress towards compliance with the guidelines during the five-year period. For purposes of determining whether an executive or non-employee director is in compliance, or making progress towards compliance, stock is valued at the greater of the value at the time of acquisition or current market value.
The table below shows the guidelines for Named Executive Officers by executive level:

Title | Stock Ownership Goal
Chief Executive Officer / President | 3.5 x Base Salary
All Other Named Executive Officers | 2 x Base Salary
Non-Employee Directors | 5 x Cash Retainer ($50,000 for 2024)
Chairman of the Board | Greater of (i) the amount set forth for Non-employee Directors; or (ii) 3 times the Chairman of the Board’s annual retainer

Under the Company’s Insider Trading Policy, Directors and Officers are subject to pledging restrictions and are prohibited from engaging in hedging transactions related to Company stock, such as puts, calls, other derivative transactions, forward sale contracts, swaps, and other arrangements intended to hedge exposure to Company stock or provide protection against declines in the value of Company stock.

EXECUTIVE EMPLOYMENT AGREEMENTS
Executive Employment Agreement with Mr. Lally
Effective May 2, 2017, the Company entered into an Executive Employment Agreement with Mr. Lally. The agreement provides for his continuous employment until the agreement is terminated in accordance with its provisions. The agreement provides Mr. Lally with severance compensation in the event of his termination under certain circumstances. The agreement contains restrictive covenants prohibiting Mr. Lally from competing with the Company during the term of his employment and for a period of either (i) 24 months following either an involuntary termination by the Company without Cause or a voluntary termination by Mr. Lally for Good Reason; or (ii) 12 months following any other terminations (the “Restricted Period”). The Employment Agreement also prohibits Mr. Lally from soliciting employees and certain customers of the Company or any of its affiliates during the Restricted Period. In addition, confidentiality provisions in the Employment Agreement prohibit the use or disclosure of confidential information.
The Company and Mr. Lally entered into an amendment to Mr. Lally’s agreement effective August 4, 2023. Under the amendment, if Mr. Lally’s employment is terminated by the Company without “Cause” or by Mr. Lally for “Good Reason” as defined in the agreement, he will be entitled to severance compensation, paid over the course of two (2) years, equal to two (2) years of base salary and an amount equal to two times the greater of (x) the average of the actual cash bonuses paid to Mr. Lally under the Company’s short-term incentive plan (the “STIP”) with respect to the two (2) fiscal years preceding the date of Mr. Lally’s termination of employment, and (y) the cash target incentive under the STIP for the year of Mr. Lally’s termination of employment as though all “target levels” of performance for such year are completely achieved. Mr. Lally would also be entitled to two years of continued medical benefits. If Mr. Lally is terminated without Cause or if he voluntarily terminates his employment for Good Reason in connection with a Change in Control (a “Change in Control Termination”), Mr. Lally will be entitled to (i) a lump sum cash payment equal to thirty-six (36) months of base salary, (ii) a lump sum cash payment equal to three (3) times the greater of (x) the average of the actual cash bonuses paid to Mr. Lally under the Company’s STIP with respect to the two (2) fiscal years preceding the date of Mr. Lally’s termination of employment, and (y) the cash target incentive under the STIP for the year of Mr. Lally’s termination of employment as though all “target levels” of performance for such year are completely achieved, (iii) a pro-rated short-term incentive award for the year in which Mr. Lally’s termination of employment occurs, (iv) continued medical benefits for a period of eighteen (18) months following Mr. Lally’s termination of employment, and (v) a lump sum cash payment equal to the value of an additional eighteen (18) months of continuation of medical benefits. In addition, if Mr. Lally experiences a Change in Control Termination, his performance-based equity awards will vest at the greater of target level or the level that corresponds to the Company’s actual performance as of the date of Mr. Lally’s termination of employment. The amendment further expands the geographic scope of Mr. Lally’s non-competition covenant to reflect the expansion of the Company’s operating territory since his original employment agreement was executed.
A “Change in Control” is defined as the first to occur of any of the following events: (i) any person, other than one or more of the directors of the Company on the effective date of the agreement or any person that any such director controls, becomes the beneficial owner of 50% of more of the combined voting power of the then outstanding voting securities of the Company entitled to vote generally in the election of directors of the Company (the “Company Outstanding Voting Securities); (ii) any person becomes the beneficial owner of 50% or more of the combined voting power of the then outstanding voting securities of the Bank entitled to vote generally in the election of directors of the Bank; (iii) consummation of a reorganization, merger or consolidation (a “Business Combination”) of the Company, unless, in each case, following such Business Combination (a) all or substantially all of the Persons who were the beneficial owners, respectively, of the Company Outstanding Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, a voting securities entitled to vote generally in the election of directors of the Company resulting from such Business Combination, (b) no person (excluding any company resulting from such Business Combination) beneficially owns, directly or indirectly, 50% or more of the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors of the Company resulting from such Business Combination except to the extent such ownership existed prior to the Business Combination, and (c) at least a majority of the members of the Company Board resulting from the Business Combination are Continuing Directors (as defined in the agreement) at the time of the execution of the definitive agreement, or the action of the Company Board, providing for such Business Combination; (iv) consummation of the sale, other than in the ordinary course of business, of substantially all of the combined assets of the Company and its subsidiaries in a transaction or series of related transactions during the course of any twelve-month period; or (v) the date on which Continuing Directors (as defined in the agreement) cease for any reason to constitute at least a majority of the Company Board.
In the event that any payments Mr. Lally would receive in connection with a change in control would constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (“Section 280G”), such payments will be reduced to the extent that such reduction would cause Mr. Lally’s net after-tax benefit to be greater than the
25

net after-tax benefit he would have received had the Company paid the full amount of the transaction payments. Upon any other termination, disability or death, neither Mr. Lally nor his estate will be entitled to any severance compensation.
Executive Employment Agreement with Mr. Turner

Mr. Turner would also be entitled to two years of continued medical benefits and the performance-based equity awards will vest at the greater of target level or the level that corresponds to the Company’s actual performance as of the date of Mr. Turner’s termination of employment. Change in Control is generally defined the same as in Mr. Lally’s agreement, except that it also includes the acquisition by a person or group of 30% or more of the total voting power of the stock of the Company.
In the event that any payments Mr. Turner would receive in connection with a change in control would constitute “parachute payments” within the meaning of Section 280G, the amendment provides that such payments will be reduced to the extent that such reduction would cause Mr. Turner’s net after-tax benefit to be greater than the net after-tax benefit he would have received had the Company paid the full amount of the transaction payments.

Our pay for performance philosophy results in a significant portion of total compensation for the NEOs being comprised of performance-based awards with both short and long-term targets. The financial performance metrics used in the performance awards are selected by the Compensation Committee to align compensation with shareholder interests and long-term value creation, while ensuring a competitive wage as compared to our peers. This has resulted in a significant level of compensation at-risk for the NEOs. In 2023, our CEOs and other NEOs total compensation included 75% and 65%, respectively, that was at risk.

Compensation actually paid to our NEOs includes the end-of-year fair value of awards granted during the year, changes in the fair value of awards granted in prior fiscal years, and other changes related to forfeited awards, as applicable.
Select items that impacted compensation actually paid and our financial measures in the table and graph above include:
•In 2020, the Company increased its allowance for credit losses due to the heightened risk to the economy and its customers because of the COVID-19 pandemic. The Company also completed an acquisition at the end of 2020, which increased the provision for credit losses and merger expense. These activities resulted in a decline in net income and EPS when compared to 2019. STIP payouts were above target, but below exceptional, and the three-year cumulative LTIP performance payouts were at 119% of target out of a maximum award of 200%. Equity markets were volatile in 2020 due to the pandemic and both the Company’s stock and the peer index had a negative return. The negative total shareholder return in 2020 reduced a portion of the LTIP award that uses this metric in the performance criteria to 29% of the targeted amount.
•In 2021, the Company completed another acquisition that resulted in additional provision for credit losses and merger expenses for the year. The Company also closed certain branch locations and recognized a related impairment charge. In support of its customers, the Company was an active participant in the Paycheck Protection Program that generated additional interest and fee income on loans. The total shareholder return for the both the Company and the peer index rebounded in 2021 with double digit returns. STIP payouts in 2021 were above target but below exceptional levels and the three-year cumulative LTIP performance payouts were at 59% of target out of a maximum award of 200%. No LTIP shares were awarded based on the three-year cumulative total shareholder return in 2021.
•In 2022, rising interest rates benefited the Company’s asset-sensitive balance sheet, resulting in an increase to net income and EPS. The Company’s total shareholder return increased in 2022, while the peer index declined. STIP payouts in 2022 were at the exceptional level and LTIP performance awards were at 132% of the aggregate target level. As noted in the compensation discussion and analysis, the NEOs also received a one-time Special Award in 2022 to increase retention.
•In 2023, net interest income continued to expand due to organic growth and an increase in market interest rates. In the industry, three large regional banks failed at the beginning of the year. The rise in short-term rates and robust deposit competition after the bank failures increased deposit costs. The provision for credit losses increased from a historically low level in 2022 and noninterest expense expanded due to higher deposit servicing costs and employee compensation and benefits. The total shareholder return for both the Company and the peer index were negative in 2023 as a result of the market disruption following the bank failures. STIP payments in 2023 were below the exceptional level due to the decline in EPS in 2023 from 2022. The LTIP performance awards were at 169% of the aggregate target level and were reflective of the three-year cumulative EPS and TSR targets.

NONQUALIFIED DEFERRED COMPENSATION
The following table sets forth information for each NEO during 2023 with respect to our Deferred Compensation Plan. Our Deferred Compensation Plan permits certain executives to participate and defer up to 25% of their base salary and/or up to 100% of their eligible bonus for a plan year. Participants can direct the investment of their accounts among the hypothetical investment alternatives made available under the plan and their accounts are adjusted for deemed investment gains or losses resulting from such investment directions. Participants make an irrevocable election when they elect to participate for a plan year to receive the vested account balance following their retirement date, or at a future date not less than five years after the beginning of the plan year. Participants may make hardship withdrawals under specific circumstances.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL
Our Named Executive Officers are entitled to severance and change in control compensation under certain termination of employment events. The amounts potentially payable to our NEOs under our Deferred Compensation Plan are set forth under the Nonqualified Deferred Compensation section above. The following table quantifies the amount of such compensation which would have been received if the qualifying event had occurred as of December 31, 2023. In the case of acceleration of unvested equity awards, the amount shown is based upon the closing price of $44.65 per share for our common stock as of December 31, 2023, and reflects the value of performance awards at target, RSUs and the net cash equivalent due the holder offset by any exercise or “strike” price for stock options.

CHIEF EXECUTIVE OFFICER PAY RATIO
Our compensation and benefits philosophy and overall structure are broadly similar across the organization to encourage and reward all employees who contribute to our success. We strive to ensure our employees’ pay reflects the level of their impact and responsibilities and is market competitive. The SEC requires companies to disclose the ratio of the annual total compensation of our chief executive officer to the median annual total compensation of our employees. The paragraphs that follow describe our methodology and the resulting pay ratio for the year ended December 31, 2023.
We previously identified our median employee using our employee population and annual compensation as of December 31, 2022. There have been no significant changes in our employee population, our employee compensation arrangements, or our median employee’s circumstances that we believe would significantly impact our pay ratio disclosure. Therefore, we calculated the 2023 pay ratio using the same median employee that we used to calculate our 2022 pay ratio. The annual total compensation of our median employee for 2023 was $85,771. Our CEO’s compensation as reported in the Summary Compensation Table was $3,445,438 for the year ended December 31, 2023. Based on these compensation amounts, our estimate of the ratio of annual total compensation of the CEO to the annual total compensation of our median employee was 40:1.
Our pay ratio is a reasonable estimate calculated based on rules and guidance provided by the SEC based on our payroll and employment records and the methodology described above. The SEC rules allow for varying methodologies for companies to identify their median employee; and other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios. Consequently, the pay ratios reported by other companies are unlikely to be relevant or meaningful for purposes of comparison to our pay ratio as reported here.
This information is being provided for compliance purposes. Neither the Compensation Committee nor management of the Company used the pay ratio measure in making compensation decisions.
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
The members of the Company’s Compensation Committee are set forth on page 12. None of the members of the Compensation Committee were officers or employees of the Company or any of its subsidiaries in 2023, nor was any member formerly an officer or employee of the Company or any of its subsidiaries. For information about related person transactions involving members of our Compensation Committee, see “Related Person Transactions - Loans to Related Persons.”
During 2023, no executive officer of the Company served as (i) a member of a compensation committee (or other Board committee performing equivalent functions or, in the absence of any such committee, the entire Board) of another entity, one of whose executive officers served on the Compensation Committee of the Company, (ii) a director of another entity, one of

whose executive officers served on the Compensation Committee, or (iii) 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 another entity, one of whose executive officers served as a director of the Company.

PROPOSAL 2. RATIFICATION OF APPOINTMENT OF DELOITTE & TOUCHE LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE YEAR ENDING DECEMBER 31, 2024

The Audit Committee has selected Deloitte & Touche LLP to be the independent registered public accounting firm for year ending December 31, 2024. Deloitte & Touche LLP acted as the Company’s independent registered public accounting firm for the year ending December 31, 2023. The Board, on behalf of the Audit Committee, recommends that the shareholders ratify the appointment of the accounting firm. Although shareholder approval is not required by law and is not binding on the Audit Committee, the appointment is submitted by the Audit Committee of the Board in order to give the shareholders a voice in the designation of auditors. If the shareholders do not ratify the selection of Deloitte & Touche LLP, the engagement of Deloitte & Touche LLP, will not be affected for year ended December 31, 2024. However, the Audit Committee will review the selection of the independent registered public accounting firm for the next fiscal year. Even if the resolution is approved, the Audit Committee of the Board in its discretion may direct the appointment of different independent registered public accounting firms at any time during the year if it determines that a change would be in the best interest of the Company and its shareholders.
Deloitte & Touche LLP representatives are expected to attend the 2024 Annual Meeting. They will have an opportunity to make a statement if they desire to do so and will be available to respond to shareholder questions.
Vote Required
The affirmative vote of holders of the majority of the shares for which votes are cast at the 2024 Annual Meeting is needed to approve this proposal. Abstentions and broker “non-votes” will not be counted as votes cast and, therefore, will not affect this proposal. Further, the failure to vote, either by proxy or in person, will not have an effect on this proposal. Unless instructions to the contrary are specified in a proxy properly voted and returned through available channels, the proxies will be voted FOR this proposal.
Recommendation of the Board of Directors
THE BOARD OF DIRECTORS, ON BEHALF OF THE AUDIT COMMITTEE, UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” THE RATIFICATION OF DELOITTE & TOUCHE LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM.
39

PROPOSAL 3. ADVISORY (NON-BINDING) APPROVAL OF EXECUTIVE COMPENSATION

We are providing our shareholders the opportunity to vote on an advisory (nonbinding) resolution to approve our executive compensation as described in the section captioned “Compensation Discussion and Analysis,” the tabular disclosure regarding compensation of our Named Executive Officers and the narrative disclosure accompanying those tables, all as set forth in pages 15 through 23 of this Proxy Statement.
The Dodd-Frank Act requires under Section 14A of the Exchange Act that companies provide their shareholders with the opportunity to cast an advisory vote to approve executive officer compensation, commonly referred to as a “Say-on-Pay” vote, at least once every three years. Our Board determined, as a result of the latest advisory vote regarding how often the Company should include a Say-on-Pay vote in its proxy materials, that we will have such an advisory Say-on-Pay vote annually.
This Say-on-Pay proposal, gives you as a shareholder the opportunity to endorse or not endorse our executive pay program through the following resolution:
“RESOLVED, that the shareholders hereby approve the compensation of the Company’s Named Executive Officers, as disclosed in the Company’s Proxy Statement for the 2024 Annual Meeting of Shareholders, including the Compensation Discussion and Analysis, the tabular disclosure regarding compensation of our Named Executive Officers and the narrative disclosure accompanying those tables.”
For the reasons set forth in this Proxy Statement, including the Compensation Discussion and Analysis, and the Report of the Compensation Committee, we believe our compensation policies and procedures are centered on a pay-for-performance culture, are competitive in our marketplace, are strongly aligned with the long-term interests of our shareholders, and that the compensation paid to our executives is consistent with such policies and procedures.
Vote Required
Your vote on this proposal is an advisory vote, which means that the Company and the Board are not required to take any action based on the outcome of the vote. However, the Board will consider the vote of our shareholders on this proposal when determining the nature and scope of future executive compensation programs and decisions.
The affirmative vote of holders of the majority of the shares for which votes are cast at the 2024 Annual Meeting is needed to approve this proposal on a non-binding advisory basis. Abstentions and broker “non-votes” will not be counted as votes cast and, therefore, will not affect this proposal. Further, the failure to vote, either by proxy or in person, will not have an effect on this proposal. Unless instructions to the contrary are specified in a proxy properly voted and returned through available channels, the proxies will be voted FOR this proposal.
Recommendation of the Board of Directors
THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” APPROVAL OF THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS.

RELATED PERSON TRANSACTIONS

Loans to Related Persons
Some of the directors, including members of the Compensation Committee, and officers of the Company and the Bank, and members of their immediate families and firms and corporations with which they are associated, have had transactions with the Bank, including borrowings and investments. All such loans and investments have been made in the ordinary course of business, have been made on substantially the same terms, including interest rate paid or charged and collateral required, as those prevailing at the time for comparable transactions with persons not related to the Company, and did not involve more than the normal risk of collectability or present other unfavorable features.
Review, Approval or Ratification with Related Persons
Our Code of Ethics requires that every employee and director avoid situations where loyalties may be divided between our interests and the employee or director’s own interests. Employees and directors must avoid conflicts of interests that interfere with the performance of their duties or are not in the best interests of the Company.
Pursuant to its written charter, the Audit Committee reviews all related-party transactions as required to be disclosed in our financial statements or periodic filings with the SEC, other than specific categories of pre-approved transactions set forth in our Related Party Transactions Policy. Related party transactions include transactions between the Company, our executive officers and directors, beneficial owners of five percent or greater of our securities, and all other related persons specified under Item 404 of Regulation S-K promulgated by the SEC. The Audit Committee considers each proposed transaction in light of the specific facts and circumstances presented, including but not limited to the risks, costs and benefits to us.

DELINQUENT SECTION 16(a) REPORTS

Section 16(a) of the Securities Exchange Act requires directors, certain officers and all persons who beneficially own more than 10 percent of our common stock file reports with the SEC with respect to beneficial ownership of our securities. We have adopted procedures to assist our directors and executive officers in complying with the Section 16(a) filings.
Based solely upon our review of the copies of the filings that we received with respect to the fiscal year that ended December 31, 2023, or written representations from certain reporting persons, we believe that all reporting persons made all filings required by Section 16(a) in a timely manner, other than a Form 4 for Mr. Guest and Ms. Van Trease that were filed late.

AUDIT COMMITTEE REPORT

The Audit Committee submits the following report:
The Audit Committee’s role includes assisting the Board in monitoring the integrity of the Company’s financial statements and related reporting process, compliance by the Company with legal and regulatory requirements, the independent registered public accounting firm qualifications, independence and performance, performance of the Company’s internal audit function and the business practices and ethical standards of the Company. The Audit Committee operates under a written charter approved by the Board.
Management is responsible for the Company’s internal controls and financial reporting process. The Company’s independent registered public accounting firm, Deloitte & Touche LLP, is responsible for performing an independent audit of the Company’s consolidated financial statements and internal control over financial reporting in accordance with standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”) and to express its opinions on the Company’s financial statements in accordance with generally accepted United States accounting principles and the Company’s internal control over financial reporting. The Audit Committee’s responsibility is to monitor and oversee these processes. In addition, the Audit Committee is directly responsible for the appointment and oversight of the independent registered public accounting firm, including review of their qualifications, independence and performance.
The Audit Committee has reviewed and discussed the Company’s audited financial statements and internal control report with management and the independent registered public accounting firm. The Audit Committee discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the PCAOB and the SEC. The Audit Committee received written disclosures and the letter from the independent registered public accounting firm as required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence and has discussed with the auditors their independence. As part of its review, the Audit Committee reviewed the fees paid to Deloitte & Touche LLP and considered whether Deloitte & Touche LLP’s performance of non-audit services for the Company was compatible with auditors’ independence. The Audit Committee has concluded that Deloitte & Touche LLP is independent from the Company and its management.
Based on the review and discussions described above, the Audit Committee recommended to the Board that the Company’s audited financial statements be included in its Annual Report on Form 10-K for the year ended December 31, 2023 for filing with the SEC.

Respectfully submitted by the following independent directors, who comprise the Audit Committee,
| Nevada A. Kent, IV, Chairperson |  | James M. Havel |  | Eloise E. Schmitz
| Lyne B. Andrich |  | Daniel A. Rodrigues |  | Sandra A. Van Trease

The foregoing report of the Audit Committee does not constitute soliciting material and should not be deemed filed or incorporated by reference into any other Company filing under the Securities Act of 1933, as amendment or the Securities Exchange Act of 1934, as amended, except to the extent the Company specifically incorporates the report by reference therein.

The Chairperson of the Audit Committee has authority to approve in advance all audit or non-audit services to be performed by the independent registered public accounting firm, but must report any such approval to the full Audit Committee at the next regularly scheduled meeting.
During the fiscal year ended December 31, 2023, all the services described under the headings “Audit Fees,” “Audit Related Fees” and “Tax Fees” were approved by the Audit Committee pursuant to the procedures described above.

PROPOSALS OF SHAREHOLDERS

Shareholders are entitled to present proposals for action at a forthcoming shareholders’ annual meeting if they comply with the requirements of the SEC proxy rules. Any proposals intended to be presented at the 2025 Annual Meeting of Shareholders of the Company must be received at the Company’s principal office at 150 North Meramec Ave., Clayton, Missouri 63105 on or before November 19, 2024, which is at least one hundred twenty (120) days prior to the anniversary date this Proxy Statement was released to our shareholders for the 2024 Annual Meeting, in order to be considered for inclusion in the Company’s proxy statement and form of proxy relating to such meeting.
Any shareholder who intends to propose any other matter to be acted upon at the 2025 Annual Meeting of Shareholders (but not include such proposal in the Company’s proxy statement) must inform the Company, in the manner specified in the Company’s By-Laws, no later than ninety nor more than one hundred twenty days prior to the first anniversary of the 2024 Annual Meeting. As a result, the notice pursuant to the Company’s By-Laws must be received by the Company no earlier than January 1, 2025 and no later than January 31, 2025. Similarly, any shareholder nomination for a director to be elected at the 2025 Annual Meeting of Shareholders must be submitted to the Company, in the manner and form specified in the Company’s By-Laws, no earlier than January 1, 2025 and no later than January 31, 2025.
No notice that a shareholder intends to present a proposal at the 2024 Annual Meeting was received by the Company on or before February 9, 2024, which was ninety (90) days prior to the one-year anniversary of the 2023 Annual Meeting of Shareholders.
45

OTHER MATTERS

As of the date of this Proxy Statement, the Board of the Company does not intend to present, nor has it been informed that other persons intend to present, any matters for action at the 2024 Annual Meeting, other than those specifically referred to herein. If, however, any other matters should properly come before the 2024 Annual Meeting, it is the intention of the persons named on the Proxy Card to vote the shares represented thereby in accordance with their judgment as to the best interests of the Company on such matters.

HOUSEHOLDING

The SEC has adopted rules that permit companies and intermediaries, such as brokers, to satisfy delivery requirements for proxy statements with respect to two or more shareholders sharing the same address by delivering a single proxy statement addressed to those shareholders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for shareholders at cost savings for companies. We and some brokers household proxy materials, delivering a single proxy statement to multiple shareholders sharing an address unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker or us that they or we will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement (which will be promptly delivered upon such request), or if you are receiving multiple copies of the proxy statement and wish to receive only one, please notify your broker or nominee if your shares are held in a brokerage account or other account or our agent, Broadridge Financial Services, Inc. (“Broadridge”) if you hold registered shares. You can notify Broadridge by sending written request to: Broadridge, 51 Mercedes Way, Edgewood NY 11717, or calling Broadridge at 1-800-353-0103.

APPENDIX A
USE OF NON-GAAP FINANCIAL MEASURES
The Company’s accounting and reporting policies conform to U.S. GAAP and the prevailing practices in the banking industry. However, the Company provides other financial measures, such as tangible book value per common share, pre-provision net revenue return on average assets, and adjusted return on average tangible common equity in this report that are considered “non-GAAP financial measures.” Generally, a non-GAAP financial measure is a numerical measure of a company’s financial performance, financial position, or cash flows that exclude (or include) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP.
The Company considers its tangible book value per common share, pre-provision net revenue return on average assets, and adjusted return on average tangible common equity collectively “core performance measures” presented in this report, as relevant measures of financial performance, even though they are non-GAAP measures, as they provide supplemental information by which to evaluate the impact of certain non-comparable items, and the Company’s operating performance on an ongoing basis. The attached tables contain a reconciliation of these performance measures to the GAAP measures.
The Company believes these non-GAAP measures and ratios, when taken together with the corresponding GAAP measures and ratios, provide meaningful supplemental information regarding the Company’s performance and capital strength. The Company’s management uses, and believes investors benefit from referring to, these non-GAAP measures and ratios in assessing the Company’s operating results and related trends and when forecasting future periods. However, these non-GAAP measures and ratios should be considered in addition to, and not as a substitute for or preferable to, ratios prepared in accordance with GAAP. The Company has provided a reconciliation of, where applicable, the most comparable GAAP financial measures and ratios to the non-GAAP financial measures and ratios, or a reconciliation of the non-GAAP calculation of the financial measure for the periods indicated.
