Proposal 1 - Election of Directors

Directors and Nominees

The Board of Director currently consists of eleven members, ten of whom are non-employeedirectors. Miguel A. Capriles L., who has been a Director since 2003, will not stand for reelection and as a result Mr. Capriles L.'s term as director of the Company will end immediately before the Annual Meeting. Upon the expiration of Mr. Capriles L's term immediately before the Annual Meeting, the size of the Board will be contracted from eleven to ten members.

As of the date of this proxy statement, the Board has determined that ten directors is an appropriate size for the Board and, accordingly, the Board has nominated, upon the recommendation of the Corporate Governance, Nominating and Sustainability Committee (the "Governance Committee"), the ten individuals identified below, who are currently directors, to serve as directors and to hold office until the next annual meeting or until their successors shall be duly elected and qualified.

The names of, and certain information with respect to, the nominees of the Board for election as directors are set forth below. If, for any reason, any nominee should become unable or unwilling to serve as a director, the Board may either reduce the number of directors to be elected or select a substitute nominee. If a substitute nominee is selected, the persons named in the proxy card may exercise their discretion to vote your shares for the substitute nominee.

The Board has determined that Mmes. Dana, Knight, Lutoff-Perlo and Rucker and Messrs. Almeida Junior, Marturet M., Quill, Suarez and Wilson, qualify as independent directors in accordance with the applicable independence requirements of the NYSE. Mr. Almeida Junior and Mrs. Lutoff-Perlo were identified as directors by a third-party search firm engaged by the Company, and were appointed to our Board on January 22, 2025. The NYSE independence requirements includes a series of objective tests, including that the director is not an employee or former executive of the Company and has not engaged in various types of business dealings with us. In addition, the Board has made a subjective determination as to each independent director that no relationships exist, which, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Until the end of 2024, under the applicable NYSE listing standards, Mr. Wilson could not qualify as an independent director as he was employed by the Company until March 19, 2021. Specifically, under the NYSE listing standards a director is not independent if the director has been an employee of the Company within the last three years; or if the director had received during any twelve-month period within the preceding three years more than $120,000 in direct compensation from the Company, excluding director compensation. The three-year period since Mr. Wilson was employed by the Company ended on March 18, 2024, and the twelve-month period within the last three-years since Mr. Wilson received more than $120,000 in direct compensation from the Company (excluding director compensation) ended on December 31, 2024. In January of 2025, the Governance Committee and the Board, after considering relevant facts, made a subjective determination that no relationships exist, which, in the opinion of the Governance Committee and the Board, would interfere with Mr. Wilson's exercise of independent judgment in carrying out his responsibilities as a director.

As disclosed in the Related Party Transactions section of this Proxy Statement, Mr. Marturet's brother-in-lawis a salaried employee of Amerant and his total compensation is in excess of $120,000. However, Mr. Marturet's brother-in-law is not an executive officer of the Company and, in addition, his compensation was established by us in accordance with our compensation practices, generally, and applicable to employees in similar positions with comparable qualifications, tenure, and responsibilities and without the involvement of Mr. Marturet M., therefore, Mr. Marturet's independence is not affected by the NYSE Listed Company Manual rules 303A.02(b)(i) and 303A.02(b)(ii).

The Board believes that the director nominees as a whole will provide the diversity of background, experience, expertise and skills necessary for a well-functioning Board and that there are sufficient independent directors to staff the independent committees of the Board and provide independent oversight. The Board values highly the ability of individual directors to contribute to a constructive Board environment and the Board believes that the current director nominees, collectively, perform in such a manner. We have a mix of age and shorter tenured and longer tenured directors to help ensure fresh perspectives as well as continuity and experience. Set forth below is a more complete description of each director's background, professional experience, qualifications, and skills.

Proposal 1 - Election of Directors

The chart below provides information regarding our director nominees skills and experience that we consider to be most

relevant based on our business, our strategy and risks. Our director nominees have different backgrounds and experiences, and each of them possesses other personal attributes not identified below. Immediately below the chart there is additional information on the reasons we consider such knowledge, skills and experience as relevant. Each director also contributes other important qualifications, expertise, experience, and viewpoints; the fact that a nominee is not designated as having a particular skill or attribute does not mean that the nominee completely lacks experience regarding that skill or attribute or would not be able to make a meaningful contribution to the Board's decision-making or oversight in that area.

Information About Director Nominees

The Board has nominated the individuals listed below to be elected directors of the Company at the Annual Meeting. In connection with his or her election to the Company's Board, these nominees are expected to also be elected to the board of the Company's wholly-owned bank subsidiary, Amerant Bank, N.A. (the "Bank").

The following sets forth self-reported biographical information the Company has obtained from the director nominees, including each director's age on the date of this Proxy Statement, employment and business experience, current director positions, the year in which the nominee became a director of the Company, and other information. The following also sets forth the director's particular qualifications, experience, skills or expertise that, when considered in the aggregate, led the Governance Committee to recommend that person as a nominee to serve as a director of the Company.

Proposal 1 - Election of Directors

For uncontested director elections, our bylaws require each director nominee to be elected by the majority of the votes cast for the election of directors at a meeting of shareholders. Under our Director Resignation Policy, as described in our Corporate Governance Guidelines, any nominee who does not receive a majority of votes cast "for" his or her election shall promptly tender his or her resignation following the failure to receive the required vote. Within 90 days of the certification of the shareholder vote, the Governance Committee would then be required to make a recommendation to the Board as to whether the Board should accept the resignation, and the Board would be required to decide whether to accept the resignation and publicly disclose its decision. In a contested director election, the required vote would be a plurality of votes cast. Full details of this policy are set forth in the Corporate Governance Guidelines available on our website.

Meetings and Attendance

During the fiscal year ended December 31, 2024, the Board held eighteen meetings. In addition, the Board held a two-dayspecial session in the third quarter of 2024 to discuss the strategy for the 2025-27period. In 2024, the Board held more meetings than previous years due mainly to the sale of the Bank's Houston franchise and the capital raise completed by the Company in the third quarter of 2024.

Other than Mr. Quelch (see explanation below), all directors attended at least 75% of the aggregate of (i) the Board meetings held during their tenure as directors during 2024 and (ii) the meetings of any committees held during their tenure as members of such committees during 2024. Mr. Quelch, who did not stand for reelection in the annual meeting held in May 2024, was unable to attend the meetings of the Board and of the Audit and Corporate Governance, Nominating and Sustainability Committees held between January and the end of April 2024 due to professional commitments outside of the United States of America.

The Board's unwritten policy regarding director attendance at the annual meeting of shareholders is that directors are encouraged but not required to attend the annual meeting. All of the then-incumbent members of the Board participated in the 2024 annual meeting of shareholders.

Executive Sessions of the Independent Directors

The Company's independent directors meet separately from the other directors and management in regularly scheduled executive sessions at least twice annually, and at such other times as may be deemed appropriate by the Company's Lead Independent Director or the other independent directors. Our Board believes this is an important governance practice that enables the Board to discuss matters without management present. Pamella J. Dana, our Lead Independent Director, presides over the executive sessions of the independent directors. Any independent director may call an executive session of independent directors at any time. The independent directors met four times in executive session without management in 2024.

Director Orientation and Continuing Education

Our director education program assists Board members in fulfilling their responsibilities. To facilitate integration into their roles, the Governance Committee working with management provides an orientation program for new directors. The director orientation program is designed to familiarize new directors with the Company's history, mission, vision, precepts, strategic plan, business, senior leadership, risk management and compliance matters, Corporate Governance Guidelines, Code of Conduct and Ethics, Insider Trading Policy and other key policies and practices. The orientation program is delivered via in-personsession(s) through a comprehensive review of background materials and senior management briefings.

Continuing education is provided through presentations from senior management and from third-party subject matter experts on subjects that are relevant to our business and operations. These presentations may occur as part of regular meetings of the board and/or its committees. In 2024, directors were provided with education on subjects including the following: state of banking and industry trends; climate risks and opportunities for banks; understanding and protecting against the risks of generative AI; and key laws, regulations, and supervisory requirements applicable to the Company and its subsidiaries.

In addition, we encourage our directors to participate in continuing director education programs offered by third parties including industry forums on business, risk, audit, financial, accounting, legal, and other subjects relevant to the Company's business to help them stay current on emerging practices and issues and in carrying out their responsibilities. The Company reimburses reasonable costs and expenses incurred by directors for continuing education that is relevant to public companies and to their roles as directors.

Finally, through memberships in the National Association of Corporate Directors and BankDirector, which are paid by the Company, our directors have access and take advantage of on demand learning courses, materials, and other resources.

Corporate Governance

The charter also provides that the Compensation Committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, legal counsel or other adviser and will be directly responsible for the appointment, compensation and oversight of the work of any such adviser. However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the Compensation Committee will consider the independence of each such adviser, including the factors required by the NYSE and the SEC.

The Compensation Committee may, in its discretion, delegate all or a portion of its duties and responsibilities to a subcommittee of the Compensation Committee and it may also delegate to one or more officers of the Company its authority to approve grants of stock options and other equity-based awards, subject to the terms and conditions of such delegation and applicable plans and law. Except for the delegation to the Company's Chairman, President and CEO of its authority to grant restricted stock under the 2018 Equity and Incentive Compensation Plan as described below, the Compensation Committee has not delegated any portion of its duties and responsibilities at this time.

On January 16, 2024, the Compensation Committee delegated its authority to grant certain equity compensation awards under the 2018 Equity and Incentive Compensation Plan to Mr. Gerald P. Plush, the Company's Chairman, President, and CEO. Under this delegation, Mr. Plush is authorized to grant up to a total of 150,000 shares of Class A Voting Common Stock of the Company for recruiting or retention of key talent, provided that he (i) not use the authorization to grant shares for himself, any other NEO or Section 16 Officer, or Director and (ii) provide at least semi-annual reports to the Compensation Committee of any grants approved under this delegation.

Compensation Committee Interlocks and Insider Participation

From the month of January 2024 until December 31, 2024, the members of the Compensation Committee were Ashaki Rucker, who chairs the Compensation Committee, Pamella J. Dana, Gustavo Marturet M., and Oscar Suarez. None of the members of the Compensation Committee in 2024 had any interlocks required to be disclosed under Item 407(e)(4) of Regulation S-K.

Except for Mr. Marturet M., none of the members of the Compensation Committee in 2024 had any relationships requiring disclosure by the Company as a related party transaction under Item 404 of Regulation S-K.Mr. Marturet M.'s brother-in-lawis a salaried employee but not an executive officer of the Company and received total compensation of approximately $300,000 in 2024. His compensation was established by us in accordance with our compensation practices, generally, and applicable to employees in similar positions with comparable qualifications, tenure, and responsibilities and without the involvement of Mr. Marturet M.

During 2024, none of our executive officers served as a member of the compensation committee or the board of directors of any other company that has one or more executive officers serving on our Board or our Compensation Committee.

Corporate Governance, Nominating and Sustainability Committee

The Board has determined that all Governance Committee members are independent under the NYSE and SEC rules.

Risk Committee

As of the date of this Proxy Statement, the Board has determined that all Risk Committee members are independent under the NYSE and SEC rules. In 2024, Mr. Wilson, who served on the Risk Committee, was not deemed independent. In January 2025, the Board concluded that Mr. Wilson is independent under applicable NYSE and SEC rules, see "Proposal 1 - Election of Directors - Directors and Nominees" in this Proxy Statement.

Key responsibilities:

Board Leadership Structure

The Board's primary responsibility is to provide effective governance over the Company's affairs and seeing that our business is managed to meet our goals and objectives and that the long-term interests of our shareholders are served. The Corporate Governance Guidelines adopted by the Board do not establish a fixed policy with respect to the separation of the offices of Chairperson and Chief Executive Officer. The Board believes that it should have flexibility to select the Chairperson and decide on the Board leadership structure, from time to time, in the context of the Company's specific circumstances at the time the determination is made and based on considerations that it deems to be in the best interests of the Company and its shareholders. The Bylaws of the Company and the Corporate Governance Guidelines provide that in the event the positions of Chairperson and Chief Executive Officer are held by the same person, the Board of Directors must appoint a Lead Independent Director from among its non-executivemembers.

Since June 2022, following the recommendation of the Governance Committee, Gerald P. Plush, who also serves as the Company's President and Chief Executive Officer, was appointed by the Board as Chairman of the Board and, in connection with the appointment of Mr. Plush as Chairman of the Board, the Board also resolved to appoint Pamella J. Dana, Ph.D as Lead Independent Director. After the annual meeting held in May 2024, following the recommendation of the Governance Committee, the Board resolved to reappoint Mr. Plush and Dr. Dana as Chairman of the Board and Lead Independent Director, respectively. The Board evaluates its leadership structure annually to make changes as it deems appropriate.

The Board considers that Mr. Plush's knowledge of the Company, its strategy and goals, his deep knowledge and understanding of the financial services industry and the challenges it is facing, coupled with his experience as President and Chief Executive Officer and his demonstrated leadership capabilities, benefits the Company, its employees, and shareholders. The Board believes that leadership by our Chairman, President and Chief Executive Officer, combined with oversight from our Lead Independent Director, and our strong, well-qualified directors (all of whom are independent, except for Mr. Plush), Board Committee members and Board Committee Chairs provide an effective and independent oversight of the Company and allow the Company to implement and execute its business plan and key strategic initiatives at this time while meeting the challenges facing the industry and expectations of our shareholders.

22 

Corporate Governance

Lead Independent Director

In 2022, the Board appointed Pamella J. Dana, Ph.D as Lead Independent Director of the Board, a position with robust responsibilities. Dr. Dana brings extensive leadership, policymaking and public affairs experience, and her long-term tenure as an independent director of the Company provides her with significant knowledge of the issues facing the Company and will ensure that those issues be considered by the Board.

The primary responsibilities of the Lead Independent Director include the following:

In addition to the Chairman, President and Chief Executive Officer and the Lead Independent Director, the Board leadership and oversight framework is complemented by talented and experienced independent directors and the standing committees of the Board. The Company believes that the current Board leadership structure, policies, and practices, when combined with the Company's other governance policies and procedures, is appropriate and serves the best interest of our shareholders.

Board and Board Committee Performance Evaluations

Each year, the Governance Committee organizes and oversees an annual evaluation by the Board and its Committees of their performance. The evaluation process is aimed at assessing the performance of the Board and its Committees and its overall effectiveness in fulfilling its responsibilities as well as identifying areas for improvement.

In 2024, the Board and the Board Committees utilized self-evaluation questionnaires to conduct Board and Board Committees' evaluations. These open-ended questionnaires focused on a variety of topics, including board and committee composition, information and resources, effectiveness and oversight as well as Board and Committee leadership. The results of the Board and each Committee evaluation were reported to and discussed by each Committee and the full Board.

The evaluation process also includes individual questionnaires for each director wherein each evaluates their peers and self-assesses their performance. The Lead Independent Director meets separately with each director to discuss the results of their evaluations and provide feedback on behalf of the other directors.

In response to feedback from these evaluations, our Board and Committees work with management to improve processes and procedures to enhance the Board and Committees effectiveness. In response to feedback from our Board and Committees in 2024, we:

23 

Corporate Governance

In 2024, the Governance Committee and the full Board reviewed the effectiveness of the overall evaluation process and decided to engage a third-party consultant to evaluate the individual performance of directors in 2025. The Governance Committee and the Board also agreed that it may use a third-party consultant to evaluate the performance of the Board and Board Committees as well.

Succession Planning

CEO and management succession planning are the responsibility of the Board. The Governance Committee is charged with assisting the Board in evaluating potential successors to the Company's Chief Executive Officer, as well as with the annual review and recommendation to the Board of an emergency and temporary CEO and a succession plan for other key positions. In addition, the Compensation Committee oversees our talent management efforts and assists the Board in identifying and developing the Company's future leaders.

In 2024, the Governance Committee retained the services of a reputable third-party leadership advisory firm, to assist the Governance Committee and the Board in establishing a CEO succession planning framework and process. With the assistance of the third-party leadership firm, the Governance Committee and the Board began developing a role specification that considers the experience, leadership capabilities, skills and attributes that the Board believes are most critical to leadership of the Company considering our business strategy, industry trends and challenges. Since CEO succession planning will be an ongoing process, the role specification is expected to be constantly reviewed, evaluated and updated as appropriate.

In furtherance of this succession planning process, the Governance Committee and the Board leveraged the services of the third-party leadership advisory firm to assess potential future internal candidates. The results of these assessments were discussed with the full Board along with the executive development plans for those individuals. In addition, to these assessments, these individuals and other members of senior management from business and support units regularly present to the Board in regular meetings of the Board and strategy sessions. These interactions provide Board members the ongoing ability to assess the capabilities and development of these senior leaders.

Information Security Oversight

Information Security is a significant component of our enterprise risk management framework. We are actively engaged in identifying and managing cybersecurity risks. Protecting company data, non-publiccustomer and employee data, and the systems that collect, process, and maintain this information is deemed critical. We have an enterprise-wide Information Security Program, which is designed to protect the confidentiality, integrity and availability of customer non-publicinformation and company data. The Information Security Program was also designed to protect our operations and assets through a continuous and comprehensive cybersecurity detection, protection and prevention program. For additional information on our Information Security Program, see Item 1C. Cybersecurity in our Annual Report on Form 10-Kfor the year ended December 31, 2024, filed on March 5, 2025 with the SEC.

Sustainability

Amerant has a long and proud history of community involvement and engagement. We launched our sustainability program in 2021 and formalized a framework to identify opportunities that can make a positive impact on sustainability, in the short term and over the long term. In 2022, we established a sustainability unit and created "Impact", the brand identity of our sustainability program that aims to tell a story of what Amerant means to do and accomplish as a community bank. We want to create social and environmental value for our people, communities, and customers. With our "Impact" program, we have a framework to identify opportunities that can make a positive impact in everything that we do through our operations, products, and services.

Our Board of Directors and senior executive team have the overall responsibility over our program and team members at all levels of the organization contribute to the achievements of our impact program goals. The Governance Committee is the primary committee responsible for overseeing, evaluating, and monitoring the implementation of the Company's Impact Program.

Some of the key initiatives and practices implemented in 2024 towards the achievements of our goals include the following:

Corporate Governance

Identification and Evaluation of Director Candidates

The Governance Committee and the Board regularly review the size and composition of the Board. The Governance Committee is responsible for identifying and recommending to the Board potential directors for nomination. The Governance Committee also considers Board succession planning and committee membership. In 2024, as part of its regular succession planning process, the Governance Committee retained a reputable third-party firm to assist and advise with board succession planning.

With the advice of the third-party advisory firm, the Governance Committee developed a process for the review and analysis of the Board's composition, including identification of priority characteristics related to experience, expertise, skills, attributes and diversity of future director candidates as well as an assessment of incumbent directors aimed at evaluating each director's performance, contribution, judgment, skills, level of engagement, tenure, and meeting attendance record.

If the Governance Committee determines that adding a new director is advisable or if a vacancy on the Board arises, the Governance Committee uses a variety of methods for identifying potential director candidates, including third-party search firms, as well as considering candidates proposed by directors and management.

Additionally, the Governance Committee will consider persons nominated by shareholders in compliance with applicable law and our Bylaws and recommend to the full Board whether such nominee should be included with the Board's nominees for election by shareholders. Our Bylaws contain provisions that address the process (including the required information and deadlines) by which a shareholder of our Class A Voting Common Stock may nominate an individual for consideration by the Governance Committee to stand for election at an annual meeting of shareholders. Our Bylaws provide certain requirements as to the form and content of a Nominating Shareholder's notice. These provisions may preclude shareholders from making nominations for directors at an annual meeting of shareholders. See the section titled "Shareholder Proposals for the 2026 Annual Meeting" in this Proxy Statement.

Information regarding potential candidates is presented to the Governance Committee, which then evaluates the candidates based on the needs of the Board at that time and the qualifications, skills, attributes and experience of the candidates. The Governance Committee considers and evaluates all candidates according to the same criteria, regardless of whether the candidate is recommended by the Governance Committee, a shareholder, another director, management or another third party. The evaluation is aimed at ensuring that the Board, as a whole, possesses the qualifications, skills, attributes and experience relevant for effectively performing its role in corporate oversight and governance.

As more fully detailed in the Company's Corporate Governance Guidelines, the Governance Committee seeks directors who:

The Governance Committee and the Board believe that diversity contributes to the overall effectiveness of the Board and consider that it is relevant for the Board to have a wealth of experience to inform its decisions. As detailed in the Company's Corporate Governance Guidelines, diversity is conceptualized expansively and includes work experience, professional skills, education, race, ethnicity, gender and other qualities or attributes that may contribute to Board heterogeneity. In addition, the process of evaluating and nominating directors also considers issues of judgment, conflicts of interest, integrity, ethics and commitment to the goal of maximizing shareholder value as well as the interplay of the individual director's or possible nominee's experience with the experience of the Board and the extent to which the individual director or possible nominee would be a desirable addition to the Board and its committees. The goal of this process is to assemble a group of directors with deep, varied experience, sound judgment and commitment to the Company's success. Accordingly, the Governance Committee considers not only an individual director's or possible nominee's qualities, performance, and professional responsibilities, but also the then-current composition of the Board and the challenges and needs of the Board to ensure that the Board, at any time, is comprised of a diverse group of members who, individually and collectively, best serve the needs of the Company and its shareholders.

27 

Corporate Governance

In 2024, the Corporate Governance Committee used the same reputable third-party firm that assisted and advised the Governance Committee and the Board with board succession planning to assist: (i) in identifying potential Board candidates who meet the qualification and experience requirements defined by the Governance Committee and the Board; and (ii) to compile and evaluate information regarding each such candidate's qualifications, experience, and education. In this search process, the Governance Committee requested that the firm prioritize the inclusion of candidates with public company experience at the C-suitelevel and that live within the markets that we serve. Through this engagement, our third-party search firm identified Mr. Almeida Junior and Mrs. Lutoff-Perlo as nominees, each of whom were appointed to our Board on January 22, 2025.

Shareholder Engagement

The Board recognizes the value of developing and maintaining solid relationships with the Company's shareholders and other stakeholders to understand their viewpoints on relevant issues such as risk management, corporate governance and sustainability. The Company engages with its shareholders on a regular basis, not limited to the proxy season.

Our senior management, including our Chairman, President and CEO, our Chief Financial Officer and our Head of Investor Relations and Sustainability, routinely participates in investor and industry conferences throughout the year to share information on our corporate strategy, financial performance, long-term objectives, liquidity and capital management, corporate governance and sustainability related matters. Feedback and perspectives received in these events are reported by senior management to the Board. In addition, senior management also holds regular discussions with investment bankers, analysts, proxy advisory firms, rating agencies, and consultants on issues of importance to our stakeholders.

At the 2024 annual meeting of shareholders, our shareholders approved the compensation of our NEOs on an advisory basis, with 79.3% of the votes cast "For" such proposal. The Compensation Committee interpreted this level of shareholder support for the executive compensation program as indicating that investor outreach was needed to better understand the views of certain shareholders with respect to our executive compensation program and their investor experience. Following the 2024 annual meeting of shareholders, we embarked on an investor outreach initiative to solicit input from our shareholders regarding our executive compensation program and plan design. For a summary on our 2024 investor outreach project, including a summary of the feedback received and action taken, see "2024 Say-on-PayVote and Shareholder Engagement" in the Compensation Discussion and Analysis section of this Proxy Statement.

In addition, as provided in our Corporate Governance Guidelines, in response to shareholders' vote, the Board shall perform an assessment in instances where 25% or more of the shareholders vote against a management-sponsored proposal or vote for a shareholder proposal. The assessment shall closely examine the concerns of shareholders and, where appropriate, respond to those concerns. Since we became a public company, none of management's sponsored proposals have received a vote against of 25% or more and we have never received a shareholder proposal for consideration in our previous annual meetings.

Report of the Audit Committee

The Audit Committee assists the Board in its oversight of the integrity of the Company's financial statements and reporting process; the qualifications, independence, and performance of the independent registered public accounting firm; and the performance of the internal audit function.

Management has the primary responsibility for the financial statements and the reporting process, including the systems of internal controls over financial reporting. The Company's independent registered public accounting firm is responsible for performing an independent audit of our consolidated financial statements and internal controls over financial reporting in accordance with the auditing standards of the Public Company Accounting Oversight Board ("PCAOB") and to issue a report thereon. Members of the Audit Committee are not full-time employees of the Company and are not, and do not represent themselves to be, performing the functions of auditors or accountants. Accordingly, as described above, the Audit Committee provides oversight of the responsibilities of management and the independent registered public accounting firm.

In the performance of its oversight function, the Audit Committee has reviewed and discussed the audited financial statements of the Company for the fiscal year ended December 31, 2024 with management and with RSM US LLP ("RSM"), the Company's independent registered public accounting firm for the fiscal year ended December 31, 2024. The Audit Committee has also discussed with RSM those matters required to be discussed by applicable requirements of the PCAOB and the Securities and Exchange Commission, including the matters required to be discussed by Auditing Standard No. 16, Communications with Audit Committees.

In addition, the Audit Committee has received the written disclosures and the letter from RSM required by the PCAOB's Ethics and Independence Rule 3526, Communication with Audit Committees Concerning Independence, as currently in effect, and the Audit Committee has discussed RSM's independence with RSM.

Based on the reviews and discussions described in this Report, and subject to the limitations of the role and responsibilities of the Audit Committee referred to above and as provided in its written charter, the Audit Committee recommended that the Board approve the inclusion of the Company's audited financial statements in Amerant's Annual Report on Form 10-Kfor the fiscal year ended December 31, 2024 that was filed on March 5, 2025 with the Securities and Exchange Commission.

Section 16(a) Reporting Compliance

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires the Company's directors, certain of its officers, and persons who beneficially own more than 10 percent of the Company's voting common stock, to file with the Securities and Exchange Commission initial reports of ownership of equity securities of the Company's and any subsequent changes in that ownership. Specific due dates for these reports have been established by the Securities and Exchange Commission and the Company is required to disclose in this proxy statement any late filings or known failures to file.

To the Company's knowledge, based solely on our review of such reports filed with the SEC and written representations that no other reports were required during the fiscal year ended December 31, 2024, all Section 16(a) filing requirements applicable to the Company's officers and directors during 2024 were met, except for one report each for Ms. Calderon and Mr. Fleitas regarding the vesting of restricted stock that were inadvertently filed late.

Certain Relationships and Related Party Transactions

From time to time, the Company or one of its subsidiaries may enter into transactions with certain "related person". Related persons include our directors (including nominees for election as directors), executive officers, holders of more than 5% of our common stock, members of the immediate family of these persons and entities in which one of these persons has a direct or indirect material interest. Generally, transactions with related persons are known as "related party transactions".

Policies and Procedures Regarding Related Party Transactions

Transactions by the Company or its subsidiaries with related parties are subject to certain regulatory requirements and restrictions, including Sections 23A and 23B of the Federal Reserve Act and Federal Reserve Regulation W. Under applicable SEC and the NYSE rules, related party transactions are transactions in which we are a participant, the amount involved exceeds $120,000 and a related party has or will have a direct or indirect material interest.

Federal Reserve Regulation O requires loans and other "extensions of credit" made to executive officers, directors and their related interests and to persons beneficially owning with their family 10% or more of the voting securities of a bank or its bank holding company to be made on substantially the same terms, including interest rates and collateral, and following credit-underwriting procedures, that are no less stringent than those prevailing at the time for comparable transactions by the Bank with other persons. Such loans also may not involve more than the normal risk of repayment or present other unfavorable features. The Board would review any loan to a director or his or her related interests that has become criticized in order to determine the impact that such classification has on the director's independence. In addition, the Audit Committee Charter provides that the Audit Committee will review and approve all related-party transactions.

We have adopted a Related Party Transaction Policy governing the review and approval of transactions with related parties, including those transactions that are expected to exceed $120,000 in any fiscal year. The policy calls for the related party transactions to be reviewed and, if deemed appropriate, approved or ratified by our Audit Committee. Upon determination that a transaction requires review under the policy, the material facts are required to be presented to the Audit Committee. In determining whether or not to approve a related party transaction, our Audit Committee will take into account, among other relevant factors, whether the related party transaction is in conformity with our Code of Conduct and Ethics and is in our best interest, whether the transaction would be in the ordinary course of our business; and whether the related party transaction is entered into on terms no less favorable to the Company than terms generally available to an unaffiliated third-party under the same or similar circumstances and the extent of the Related Person's interest in the transaction. In the event that we become aware of a related party transaction that was not approved under the policy, our Audit Committee will review such transaction as promptly as reasonably practical and will take such course of action as may be deemed appropriate under the circumstances. In the event a member of our Audit Committee is not disinterested with respect to the related party transaction under review, that member may not participate in the review, approval or ratification of that related party transaction.

Certain transactions are not subject to the related party transaction approval policy, including: (1) decisions on compensation or benefits relating to directors or executive officers or reimbursements for business travel and expenses, (2) credit extensions by us in the ordinary course of business, on substantially the same terms, including interest rate and collateral, as those prevailing at the time for comparable loans with persons not related to us and not presenting more than the normal risk of collectability or other unfavorable features, and approved by the Board or an authorized Board or management committee in accordance with our policies or procedures or applicable law, and (3) other financial services, including brokerage services, banking services or services as a bank depositary of funds, transfer agent, registrar, trust or similar services provided by the Company provided that the services are on substantially the same terms as those prevailing at the time for comparable services provided to persons that are not related parties.

Certain Relationships and Related Party Transactions

Related Party Transactions

The brother-in-law of Gustavo Marturet M., one of our directors, is a salaried employee of ours and received total compensation of approximately $300,000 in 2024. His compensation was established by us in accordance with our compensation practices, generally, and applicable to employees in similar positions with comparable qualifications, tenure and responsibilities and without the involvement of Mr. Marturet M. This employee is not an executive officer of the Company.

Various Company directors, officers, and their affiliates, including corporations and firms of which they are directors or officers or in which they and/or their families have an ownership interest, are customers of the Bank and its subsidiaries. In the ordinary course of business, the Bank has engaged and expects to continue engaging into ordinary banking transactions with these persons and entities, including borrowings, all of which are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons not related to the Company or the Bank and do not involve more than the normal risk of collectability or present other unfavorable features.

Executive Compensation

Compensation Discussion and Analysis

This Compensation Discussion and Analysis ("CD&A") describes the philosophy, components, and additional aspects of our 2024 executive compensation program and is intended to be read in conjunction with the tables that immediately follow this section, which provide further information on executive compensation. Unless the context requires otherwise, for purposes of this section, references to "the Company" refer to Amerant Bancorp Inc. and its subsidiaries, including Amerant Bank, N.A. Our "named executive officers" or "NEOs" for the year ended December 31, 2024, were as follows:

2024 Financial and Strategic Highlights

In 2024, Amerant completed a multiyear transformation effort, and will now transition to the execution and implementation of its strategic growth plan. Amerant delivered a strong performance in our core business in 2024, despite the current interest rate environment and continued economic uncertainty. While our total loans and asset size were impacted by the sale of the $401 million Houston multifamily loan portfolio in January 2024 and the sale of our banking operations and six branches in Houston, Texas (the "Houston Franchise") in November 2024, which included the sale of approximately $497 million in assets (including cash and loans) and approximately $581 million in liabilities (including deposits and other liabilities), our loan pipeline is robust heading into 2025, and we expect to again exceed $10 billion in assets in the first quarter of 2025. During 2024, we focused on completing our transformation toward becoming the bank of choice in Florida, and in 2025, our focus is now executing on our growth plan. For the year ended December 31, 2024, Amerant achieved the following key financial and operational results:

Executive Compensation

Highlights of Our Executive Compensation Practices

The Compensation Committee has structured our executive compensation program to ensure that our NEOs are compensated in a manner consistent with shareholder interests, competitive pay practices and applicable requirements of regulatory bodies. The following are important features of the design and operation of our executive compensation program:

Components of Pay

The components of our 2024 executive compensation program consist primarily of elements that are generally available to our employees, including base salary, annual incentive cash compensation, equity awards, and broad-based benefits.

Target Pay Mix

The target pay mix supports the core principles of our executive compensation philosophy and objectives of compensating for performance and aligning executive officers' interests with those of shareholders, by emphasizing both annual and long-term incentives. The Compensation Committee allocated compensation among (i) base salary,

37 

Executive Compensation

(ii) annual cash incentive, and (iii) long-term annual equity incentive. The graphics below illustrate the allocation of annual target total direct compensation payable to the CEO and the average of the other NEOs for 2024.

The percentages of target total direct compensation as calculated above are based on the annualized 2024 base salary, the 2024 annual cash incentive compensation opportunity (assuming achievement at the target level), and the grant date fair value of the 2024 annual equity grants.

Governance of Our Pay Program

The Compensation Committee regularly reviews best practices in executive compensation and uses the following guidelines to design our compensation programs:

38 

Executive Compensation

2024 Say-on-PayVote and Shareholder Engagement

At the 2024 annual meeting of shareholders, our shareholders approved the compensation of our NEOs on an advisory basis, with 79.3% of the votes cast "For" such proposal. The Compensation Committee interpreted this level of shareholder support for the executive compensation program as indicating that investor outreach was needed to better understand the views of certain shareholders with respect to our executive compensation program and their investor experience.

Following the 2024 annual meeting of shareholders, we embarked on an investor outreach initiative to solicit input from our shareholders regarding our executive compensation program and plan design. As part of this effort, we reached out to the largest 15 institutional investors, representing approximately 38% of our outstanding shares, to engage with our shareholders' proxy voting and investor stewardship teams, to gain a better understanding of the perspectives and concerns of these shareholders. We invited shareholders to discuss our executive compensation program and plan design, as well as our corporate governance practices.

As a result of our outreach, we spoke to four shareholders, representing approximately 12% of our outstanding shares. Three shareholders representing approximately 6% of our outstanding shares declined to meet with us indicating that they had no questions or concerns at the time. One shareholder indicated a preference to meet closer to the annual meeting date. We did not receive responses from seven other shareholders we contacted.

Given the focus of these calls was on executive compensation matters, the Chair of the Compensation Committee, together with the Chief People Officer, the Head of Investor Relations and the Corporate Secretary participated in this effort on behalf of the Company. We received valuable commentary and constructive insights from shareholders we spoke with on a variety of matters and we reported this information to the Compensation Committee and the Board of Directors. In these meetings, our shareholders generally expressed a positive view with respect to our executive compensation program and they shared their views on practices from peer companies that they deemed appropriate. The compensation discussions we had with shareholders included details on the financial metrics utilized and weighting of metrics in the short-term cash incentive compensation program, as well as the use of more than one performance metric for performance based restricted stock units used in our long-term incentive plan. The shareholders we met with also shared their thoughts on how we may enhance disclosures on important governance matters like board evaluations and succession planning process.

We have considered the results of our discussions with shareholders in making decisions regarding executive compensation. These conversations confirmed that changes that were already being considered to our executive compensation program were appropriate, and consequently, the Compensation Committee decided to approve changes to some of our compensation practices. The details regarding what we heard from shareholders regarding executive compensation and corporate governance matters at these meetings and our responses to the input received and enhancements made to our compensation practices and plan design are set forth in the table below:

39 

Executive Compensation

Our Board and Compensation Committee recognizes the value of developing relationships with the Company's shareholders and believe that maintaining an active dialogue with shareholders is an important step in delivering long-term shareholder value. Although the say-on-payproposal represents a non-bindingadvisory vote, we appreciate the opinions of our shareholders and will continue to consider the outcome of future say-on-payvotes, in addition to other relevant shareholder feedback, that may be received throughout the year, when making compensation decisions for our Named Executive Officers.

Our Executive Compensation Philosophy and Objectives

The Company's compensation philosophy is the foundation of our overall compensation program and is primarily focused on providing a competitive, total rewards program in alignment with our business objectives, human capital strategy and the interests of our shareholders. We are committed to delivering a compensation program with the fundamental principles of fairness, transparency, efficiency, and compliance with laws and regulations. Based on specific job positions and market conditions, our total rewards program combines fixed and variable compensation: base salary, annual cash incentive, equity-based long-term incentive, and a broad range of benefits. This compensation approach plays a significant role in our ability to attract, retain and motivate the quality of talent necessary to achieve our strategic business goals and drive sustained performance. Our compensation model engages our team members to

contribute towards the achievement of our Company objectives, while differentiating pay on performance based on individual contributions. Our commitment to maintaining transparent compensation principles and a diverse and inclusive culture for our teams has a direct impact on engagement, drive and performance.

The Company proactively reviews the results of the compensation programs and their link to the Company's performance as part of a robust governance process led by the Compensation Committee. Policies and procedures are designed to prevent or mitigate excessive risk-taking, align pay and performance, and ensure proper governance practices. Our programs are flexible, allowing us to respond to changing dynamics in the banking industry, organizational direction, and shareholder interests.

Determination of Named Executive Officer Compensation

Role of the Compensation Committee

The Compensation Committee, which is composed entirely of independent directors, administers the Company's compensation policies and programs for the CEO and the other NEOs. The Compensation Committee annually reviews and approves Company goals and objectives relevant to the compensation of the CEO and the other NEOs. The Compensation Committee evaluates the performance of the CEO and the other NEOs considering those Company goals and objectives. The Compensation Committee then approves the calculation of the CEO's and the other NEOs' incentive compensation based on applicable performance metrics. The Compensation Committee determines and approves compensation levels for the CEO and the other NEOs based on those evaluations and any other factors as it deems appropriate, including competitive market data, individual and Company performance, skills, experience, complexity and criticality of role, and internal pay equity. The Compensation Committee reviews and approves, as applicable, (i) base salary, (ii) annual cash incentive compensation, (iii) long-term incentive compensation, generally in the form of equity or equity-linked compensation, and (iv) any other compensation, perquisites, and annual or supplemental benefits for the CEO and the other NEOs.

The Compensation Committee works closely with its independent compensation consultant in ensuring that the Company's executive compensation program rewards executives for performance while enhancing shareholder value.

During 2024, the Compensation Committee decided to complete a Request for Proposal ("RFP") process and solicited bids for independent compensation consultant services. The RFP process evaluated the consultants on experience, methodology, cost-effectiveness, and actionable recommendations. The Compensation Committee's current consultant, Aon's Human Capital Solutions practice, a division of Aon plc ("Aon"), was invited to participate in the RFP process along with three other independent compensation consultants. After a thorough review process, the Compensation Committee renewed its engagement with Aon.

Role of Management

Executive management, primarily the CEO and the Chief People Officer, assists the Compensation Committee in recommending agenda items for its meetings and by gathering and producing information for these meetings. The CEO and other executive officers may participate in Compensation Committee meetings to provide background information and other requested items but are not present during the voting or discussions of their own compensation. The CEO provides recommendations to the Compensation Committee for the other NEOs regarding compensation, performance

40 

Executive Compensation

goals, performance reviews, and other employment-related matters, such as hiring, promotions, or severance payments. The Compensation Committee considers the CEO's recommendations but retains authority to approve or recommend to the Board of Directors compensation decisions to be approved.

Role of the Independent Compensation Consultant

The Compensation Committee has directly engaged Aon as its independent compensation consultant. Aon reports to, and receives its direction from, the Compensation Committee, and a representative of Aon regularly attends Compensation Committee meetings as its independent advisor. Aon helped facilitate the executive officer compensation process, including the creation of a compensation peer group for comparing our NEOs' compensation to the market and provides advice and information on other executive compensation matters.

In reviewing Aon's performance and considering its continued engagement, the Compensation Committee evaluated Aon's independence and any conflicts of interest in accordance with the applicable SEC rules and the NYSE listing requirements. The Compensation Committee requested and received a report from Aon addressing the independence of Aon and its senior advisors. The Compensation Committee considered Aon's provision of other services to the Company, the fees paid by the Company to Aon as a percentage of Aon's total revenue, Aon's policies and procedures to prevent conflicts of interest, and the confirmation by Aon that it and its representatives have no business or personal relationship with any member of the Compensation Committee, do not own any stock of the Company, and have no business or personal relationship with any executive officer of the Company. The Compensation Committee concluded that Aon is independent of the Compensation Committee and of Company management and has no conflicts of interest in its performance of services to the Compensation Committee.

Peer Group

The Compensation Committee believes that obtaining relevant market and benchmark data is very important to making determinations about executive officer compensation. Such information provides a reference point for making decisions.

The Compensation Committee takes into consideration the structure and components of, and the amounts paid under, the executive compensation programs of other, comparable peer companies, as derived from public filings and other sources, when making decisions about the structure and component mix of our executive compensation program. The Compensation Committee also considers the practices of our competitors and the broader industry for recruiting and retaining talent.

The Compensation Committee, with the assistance of its independent consultant, developed a peer group in 2023 for use in establishing 2024 compensation. The peer group was defined using the following criteria:

The 2024 compensation peer group consisted of the following companies:

41 

Executive Compensation

Except for the removal of Lakeland Bancorp and the addition of Stellar Bancorp, the 2024 compensation peer group is identical to the 2023 compensation peer group. Lakeland Bancorp was removed from the 2024 compensation peer group because of its acquisition by Provident Financial Services (a current peer) in May 2023. Stellar Bancorp was added because it is similar in size to Amerant, making it a suitable replacement for Lakeland Bancorp.

Elements of 2024 Compensation

Base Salaries

The base salaries of our NEOs are set annually by the Compensation Committee as part of the Company's performance review process as well as upon the promotion of an executive officer to a new position or other change in job title or responsibility. In establishing base salaries for our NEOs, the Compensation Committee has relied on external market data and peer data obtained from outside sources, including its independent consultant. In addition to considering the information obtained from such sources, the Compensation Committee has considered:

The Compensation Committee approved salary increases in 2024 for all NEOs to align with the market rates for similar positions and consideration of the factors listed above. The Compensation Committee approved a larger base salary increase for Ms. Calderón due to her promotion to CFO and increased responsibilities and because her 2023 salary was significantly below market when she was appointed to the position.

2024 Annual Cash Incentive

Our NEOs are eligible to eaannual cash incentive awards based on the level of achievement of performance goals for each applicable performance cycle. In addition to meeting the performance goals for the plan, NEOs must also be employed and in good standing at the time of payment to receive an incentive payout under the plan.

Our annual cash incentive is a short-term, non-equityincentive plan that is intended to motivate and reward the NEOs' performance and contributions to our success and focus each NEO's attention on specific goals. The plan provides an annual cash incentive based on the achievement of Company performance metrics and the execution of key initiatives defined for each NEO. Under the annual cash incentive, the amount of each named executive officer's potential bonus payout that can be earned at threshold, target and maximum levels is determined as a percentage of the NEO's base salary, but those levels can be adjusted in the judgment of the Compensation Committee.

42 

Executive Compensation

Target Opportunities

The 2024 target annual cash incentive opportunities for our NEOs, expressed as a percentage of their base salary and as a dollar amount, are detailed in the following table. In consultation with Aon and based on market data and their individual performance, the Compensation Committee determined that the target opportunities for all NEOs would remain unchanged for 2024.

Company Performance Metrics

As soon as possible at the beginning of each fiscal year, the Compensation Committee sets the Company performance metrics that will be used to determine the bonus payment to be awarded to each NEO. The Company performance metrics, which aggregate overall weight, as noted above, was increased to 70% of the target annual incentive opportunity for each NEO, for 2024 included: PPNR, growth in average total core deposits, ROAA, efficiency ratio, and non-performingassets over total assets.

A specific percentage weight was allocated to each of these performance metrics as set forth in the table below. The Compensation Committee also established a threshold, target, and maximum performance level for each performance metric. If performance falls below the threshold level for any performance metric, no payment is earned; however, payment is earned for the other performance metrics that are achieved at least equal to the threshold level. Maximum represents the maximum level of performance at which a payment is earned on each performance metric. If the performance achieved for any Company performance metric is above the maximum level, no additional incentive above the maximum incentive for such performance metric is earned. Actual performance between threshold, target and maximum performance levels is interpolated to determine the amount of payment based on relative achievement of the performance metrics.

The Compensation Committee established the 2024 Company performance goals in February 2024 based on the expectation that performance results would be the same or lower than 2023 because of the anticipated increasing interest rate environment in 2024, the uncertain economic environment, continued increase in expenses due to inflation, and anticipated decrease in core deposits.

In June 2024, the Company received regulatory approval for the sale of the Houston Franchise, and that transaction closed in the fourth quarter of 2024. In light of the pending asset sale, the Board modified the 2024 budget to reflect this sale and as a result, the Compensation Committee determined that the original performance targets were no longer appropriate or achievable due to the timing of the closing of the Houston Franchise sale, which was largely outside of the management's control, due to the required regulatory approval, and not anticipated when the original performance metrics were set. At the July 2024 Compensation Committee meeting, the Compensation Committee approved adjustments to the threshold, target, and maximum goal targets to reflect the updated full-year budget and the expected sale of the Houston Franchise. At this time, the Compensation Committee also decided to measure performance for PPNR, ROAA, and Efficiency Ratio based on our core business considering that several non-routineitems were now anticipated to occur in 2024. The goal targets for the Core PPNR, Growth in Average Total Core Deposits, Core ROAA, and Core Efficiency Ratio were revised slightly lower and the goal targets for Non-PerformingAssets/Total Assets was increased slightly to reflect the sale of the Houston Franchise. The Compensation Committee believed that the revised metrics represented rigorous but reasonable goals for the business based on the expected results without the

43 

Executive Compensation

inclusion of the Houston Franchise. The adjusted threshold, target and maximum performance levels for each selected Company performance metric (70% of total) and the actual result for each Company performance metric in 2024, which led to an overall payout on the Company metrics at 48% of target, were as follows:

Performance on Key Individual Initiatives

The Compensation Committee also considers the individual evaluations performed for each NEO in relation to the execution of pre-identifiedstrategic objectives and key initiatives, which for the 2024 awards was lowered to 30% of the annual cash incentive target opportunity. NEOs are eligible to receive anywhere between 0% - 150% of target for this portion of the award. As noted above, the individual component for NEOs will be lowered to 20% in 2025.

In evaluating the performance of each NEO with respect to key individual initiatives the Compensation Committee reviews each NEO based on a set of factors related to pre-establishedgoals and initiatives related to the NEO's area of responsibility, for the NEOs other than the CEO, and for the CEO based on his achievement of key Company initiatives. Such factors related to the following for the CEO and other NEOs:

44 

Executive Compensation

As a result of this review, except for Mr. Levine, the Compensation Committee determined that Mr. Plush earned at 137.5% and the other NEOs earned at 150% of their individual targets based on their accomplishments tied to our strategic initiatives described below.

Payout Determination

The Compensation Committee verifies achievement relative to the target for the Company performance metrics and the individual performance metrics to determine the respective performance levels. The Compensation Committee then adds the amounts for the two portions together to determine the total 2024 annual cash incentive plan payout for each NEO. The total payout under our annual cash incentive plan for each NEO for 2024 is reflected in the table below.

45 

Executive Compensation

Long-Term Incentives Program

The third and largest component of the executive compensation program is long-term equity incentives. Long-term equity incentive awards are prospective in nature and intended to tie a substantial portion of an executive's pay to creating long-term shareholder value. The Compensation Committee has designed the long-term incentive opportunity to motivate and reward executive officers to achieve multi-year strategic goals and to deliver sustained long-term value to shareholders. In 2021, the Compensation Committee added PSUs to the long-term equity incentive mix and since then it grants the Company's NEOs a mix of RSUs and PSUs. The long-term incentives create a strong link between payouts and performance, and a strong alignment between the interests of executive officers and the interests of our shareholders. Long-term equity incentives also promote retention, because generally executive officers will only receive value if they remain employed by us over the required term, and they foster an ownership culture among our executive officers by making them shareholders with a personal stake in the value they are intended to create.

2024 Long-Term Incentives

For 2024, the Compensation Committee determined that the award vehicle mix should be 50% time-based RSUs and 50% PSUs based on the closing price of our common stock on the date of grant at an aggregate dollar value equal to a percentage of the NEO's annual base salary at the time of grant. In consultation with Aon and based on market data and her or his individual performance, the Compensation Committee determined the 2024 target long-term incentive opportunities as a percentage of base salary for each NEO would remain unchanged. The time-based RSUs ratably vest over a three-year period from the date of grant. As discussed further below, the PSUs use relative Total Shareholder Return, or TSR, as a metric for a three-year performance period, beginning January 1, 2024 and ending December 31, 2026.

In 2024, our NEOs were awarded the following equity grants:

The 2024 PSUs may be earned and vest upon the achievement of the Company's TSR during a performance period from January 1, 2024, through December 31, 2026, relative to the companies in our compensation peer group. As detailed in the chart below, the actual number of PSUs earned will be based on the percentile rank of Amerant's TSR relative to the TSRs of the companies in the peer group.

Interpolation is used to determine payout level in between performance levels. If the Company's absolute TSR for the performance period is a negative number (without regard to the TSR of the peer group), then irrespective of the Company's relative TSR to the peer group, the number of PSUs earned and shares issued will be capped at the Target performance level.

46 

Executive Compensation

The Compensation Committee views the inclusion of a metric that includes TSR as critical because it ties executive officer compensation with the creation of shareholder value and aligns the interests of executive officers with those of Amerant and its shareholders. By measuring our stock performance relative to peers, it mitigates the impact of macroeconomic factors, both positive and negative, that affect the industry and/or stock price performance and are beyond the control of management. Additionally, it provides rewards that are more directly aligned with performance through different economic cycles.

All equity awards are also subject to each NEO remaining in the continuous service of the Company through the vesting date.

Starting with the PSUs awarded in 2025, we are using ROATCE relative to members of the KBW Regional Banking Index, which tracks the performance of leading US banking institutions, with a TSR modifier for our performance metric. This change addresses feedback received from shareholders during the engagement process we completed in 2024 and their preference to see multiple performance metrics utilized for PSUs as opposed to just TSR. The change also addresses concerns that utilizing TSR exclusively reflects a narrow view of performance.

2022-2024 PSUs Payouts

The PSUs granted in 2022 had a three-year performance period that ended on December 31, 2024. In January 2025, the Compensation Committee certified the performance of these PSUs based on the Company's relative TSR percentile ranking against the Company's peer group. For the performance period, the Company's TSR was below the 35^th percentile, resulting in no payout for the PSUs granted in 2022. Mr. Plush and Mr. Iafigliola were the only two NEOs of the Company with outstanding 2022 PSU awards. If performance had been achieved at the target level, Mr. Plush would have been entitled to receive 14,715 shares of Class A Voting Common Stock of the Company, and Mr. Iafigliola would have been entitled to receive 3,750 shares of Class A Voting Common Stock.

Payout percentages at various levels of performance for the 2022-2024 PSUs are illustrated in the table below.

Broad-Based Benefits and Perquisites

Our NEOs are eligible to participate in the same benefit plans designed for all our full-time employees, including health, dental, vision, life and disability plans. The purpose of our employee benefit plans is to help attract and retain quality employees, including executives, by offering benefit plans similar to those typically offered by our competitors. We also provide limited perquisites for NEOs, including an executive physical, auto allowance and cell phone payments.

Life Insurance Benefits

Mr. Plush holds an individual life insurance policy that is paid in full by the Company with a death benefit totaling $2,000,000. The income taxes resulting from the imputed income attributable to Mr. Plush's death benefit are paid by Mr. Plush. 

After completing a restructure of our split-dollar life insurance plan (BOLI) program, in January 2024, the Company entered into split-dollar life insurance agreements with each of the named executive officers, except Mr. Plush. Since January 2024, the death benefit during employment for Ms. Calderón and Messrs. Esterripa, and Iafigliola is $1,250,000. The death benefit for Mr. Levine while employed by the Company was also $1,250,000.

Under the current split-dollar life insurance policy, a portion of the death benefit is endorsed to the applicable NEO, and each year the applicable NEO has an imputed income attributable to his portion of the death benefit. Each applicable NEO is then subject to income taxes on this imputed income. The Company pays each applicable NEO that has entered into a split-dollar life insurance agreement the applicable amount for the NEO to offset the income tax related to the imputed income from his portion of the death benefit.

Executive Compensation

In cases where a split-dollar life insurance agreement has been entered into with an NEO, the life insurance benefits may continue beyond termination of employment if participants have met the retirement requirements of 55 years of age and 15 years of service, or 60 years of age and 10 years of service prior to termination. At the time of his separation from the Company, Mr. Levine had not met these requirements and the split-dollar life insurance benefits were discontinued.

401(k) Plan

The Company sponsors the Amerant Bank Retirement Benefits Plan, or the 401(k) Plan, for its employees. Each employee is eligible to make contributions to the 401(k) Plan and receive matching employer contributions after attaining age 18 and three-months' of employment with the Company. The NEOs may participate in the 401(k) Plan on the same terms as the rest of the Company's employees. The 401(k) Plan is intended to be qualified under Section 401(a) of the Internal Revenue Code of 1986, as amended, or the Code. As a tax-qualifiedretirement plan, pre-taxcontributions to the 401(k) Plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) Plan. Each participant may defer eligible compensation subject to the statutory limit and participants that are 50 years or older can also make additional "catch-up"contributions above the statutory limit. As a safe harbor plan, the Company matches 100% of the first 5% of the participants' contribution to the 401(k) Plan. All contributions made by both the participants and the Company to the participants' accounts are vested immediately.

Executive Deferred Compensation Plan

The Company maintains a non-qualifieddeferred compensation plan, or the Deferred Compensation Plan, for highly compensated employees, including the NEOs. Currently, Messrs. Plush and Iafigliola participate in this plan and Mr. Esterripa and Ms. Calderón do not. Mr. Levine did not participate in this plan during 2024. The Deferred Compensation Plan is designed to prevent such employees from being disadvantaged by 401(k) Plan limits and supplements the 401(k) Plan's savings opportunities, however, it does not provide eligible employees with a matching Company contribution.

The Deferred Compensation Plan limits deferral contributions to 50% of the participant's non-bonuscompensation and 100% of the participant's annual bonus compensation and does not permit investments in Company stock. All deferrals, earnings, and gains on each participant's account in the Deferred Compensation Plan are vested immediately.

Employee Stock Purchase Plan

We have an Employee Stock Purchase Plan ("ESPP") for all eligible employees. The ESPP provides for six month offering periods commencing each December 1st and ending on May 31st of the following year and beginning on each June 1st and ending on the following November 30th. Under the terms of the ESPP, eligible employees may contribute through payroll deductions up to $21,250 (85% of IRS limitation) of their compensation toward the purchase of the Company's Class A Voting Common Stock. The price per share is equal to the lower of 85% of the fair market price on the first trading day of the offering period or 85% of the fair market price on the last trading day of the offering period. In 2024, Mr. Plush and all other NEOs who were eligible as of the enrollment deadline for each offering period in 2024, elected to participate in the ESPP.

Compensation Policies and Practices and Risk Management

Stock Ownership Guidelines

The Board considers it is in the best interests of its shareholders, and promotes the Company's commitment to sound corporate governance, that every director, NEOs, and other executives of the Company own a meaningful personal financial interest in the Company. In the Board's opinion, such an investment commits each individual to the Company's future and aligns his/her interests with those of the Company's shareholders. The stock ownership guidelines adopted by the Board require our directors and executives (including Executive Vice-Presidents) to own shares of our Class A Voting Common Stock having values equal to the applicable multiple of base salary for executives and annual cash retainer for directors, as set forth in the table below:

None of the other NEOs currently have employment agreements with the Company.

The Company has also entered into a Change in Control Agreement ("CIC Agreement") with each of the non-CEONEOs that provides for certain severance protections in the event of a change in control of the Company. The CIC Agreements for these NEOs remain in effect for 24 months following the effective date and automatically renew for an additional 12 months unless the Company notifies the NEO at least 90 days before such renewal. The CIC agreement executed between the Company and Mr. Levine was superseded by the Separation and General Release Agreement (the "Separation Agreement") entered into by and between the Company and Mr. Levine on February 14, 2025, see "Mr. Levine's Separation of Service" in this Proxy Statement.

Messrs. Iafigliola, Levine, and Esterripa and Ms. Calderón have also entered into Restrictive Covenant Agreements that include customary intellectual property, non-solicitation,non-competeand confidentiality provisions.

The terms of the arrangements related to termination and change in control for all the NEOs are described in detail in the section titled "Potential Payments Upon Termination of Change of Control".

In addition, Mr. Levine will be paid all accrued wages through the separation date, less applicable payroll deductions, and his health benefits, if any, will terminate on February 28, 2025.
