Dear Stockholder:

You are cordially invited to attend the 2024 Annual Meeting of Stockholders (the “Annual Meeting”) of SEACOR Marine Holdings Inc. (the “Company”) on Tuesday, June 4, 2024, at 9:00 a.m. (EDT). The Annual Meeting will be a completely “virtual meeting,” held via a live audio webcast at www.proxydocs.com/SMHI. All holders of record of the Company’s outstanding Common Stock at the close of business on April 15, 2024, will be entitled to vote at the Annual Meeting. Your virtual attendance at the 2024 Annual Meeting affords you the same rights and opportunities to participate as you would have at an in-person annual meeting, including the ability to vote and submit questions electronically prior to and during the meeting. We believe the virtual Annual Meeting format will enhance stockholder access and encourage participation and communication with our Board of Directors and management.

Directors, officers and other representatives of the Company are expected to be available at the virtual Annual Meeting and they will be pleased to answer any questions you may have.

Whether or not you expect to attend the Annual Meeting and regardless of the number of shares of the Company’s Common Stock you own, you are encouraged to carefully read the enclosed Proxy Statement and the Company’s Annual Report to Stockholders on Form 10-K for the fiscal year ended December 31, 2023 (the “2023 Annual Report”). You may vote your shares over the Internet at www.proxypush.com/SMHI or via the toll-free telephone number included herein. If you received a paper copy of a proxy or voting instruction card by mail, you may instead submit your proxy or voting instruction card for the Annual Meeting by completing, signing, dating and returning your proxy or voting instruction card in the pre-addressed envelope provided. Submitting a vote before the Annual Meeting will not preclude you from voting your shares at the virtual Annual Meeting should you decide to join the webcast.

We hope that you will be able to attend the virtual Annual Meeting.

For the Board of Directors,

Andrew R. Morse

Non-Executive Chairman of the Board

Proxy Statement

SOLICITATION OF PROXIES, VOTING AND REVOCATION

Voting and Quorum

A list of the Company’s stockholders as of the close of business on April 15, 2024 (the “Record Date”) will be available for examination by any stockholder, for purposes germane to the virtual Annual Meeting, during ordinary business hours for the ten-day period prior to the date of the Annual Meeting, at the offices of the Company, 12121 Wickchester Lane, Suite 500, Houston, Texas 77079.

Only record holders of our common stock, $0.01 par value per share (“Common Stock”), as of the Record Date will be entitled to vote at the Annual Meeting. Our authorized capital stock currently consists of 60,000,000 shares of Common Stock. At the close of business on the Record Date, there were 27,602,032 shares of Common Stock outstanding and entitled to vote. Each stockholder of record is entitled to one vote for each share held on the Record Date on all matters that may properly come before the Annual Meeting. There are no dissenter or appraisal rights relating to the matters to be acted upon at the Annual Meeting.

Stockholders are requested to vote in one of the following ways:

• by telephone by calling the toll-free number 1.866.859.2198 from any touch-tone telephone and following the instructions (have your proxy card in hand when you call);

• by Internet prior to the Annual Meeting by accessing www.proxypush.com/SMHI and following the on-screen instructions (have your proxy card in hand when you access the website);

• by completing, dating, signing and promptly returning the accompanying proxy card, in the enclosed postage-paid, pre-addressed envelope provided for such purpose; or

• by voting virtually at the Annual Meeting online at www.proxydocs.com/SMHI by using the control number included with these proxy materials (see the “Attending the Annual Meeting Virtually” section of this Proxy Statement).

We recommend that you vote by phone, Internet, or proxy even if you plan to virtually attend the Annual Meeting.

Shares of Common Stock represented by properly executed proxy cards or voted by telephone or Internet that are received by the Company and not subsequently revoked will be voted at the Annual Meeting in accordance with the instructions contained therein or if no instructions are contained in the proxy, as described in the “Proxy Cards” section of this Proxy Statement.

A quorum for the transaction of business at the Annual Meeting requires the holders of record of a majority in voting power of the then issued and outstanding shares of all classes and series of stock of the Company entitled to vote at the meeting, in person or by proxy.

For Proposal 1 (Election of Directors), election of the director nominees to the board of directors of the Company (the “Board”) requires the affirmative vote of a plurality of the shares of Common Stock present virtually or represented by proxy at the Annual Meeting and entitled to vote, which means that the five nominees receiving the most “for” votes will be elected. Because there are only five director nominees named in this Proxy Statement, votes withheld from any nominee will have no effect on the outcome of the election of directors. Votes may not be cast “against” the election of a nominee. Abstentions and “broker non-votes” (as described in the “Shares Held in Street Name” section of this Proxy Statement) will not affect the outcome of such election. Our stockholders do not have cumulative voting rights for the election of directors.

Matters to be considered at the meeting other than the election of directors require the vote of the holders of a majority in voting power of the shares entitled to vote present at the meeting in person or by proxy.

For Proposal 2 (Say on Pay) and Proposal 3 (Ratification of the Appointment of Independent Registered Public Accounting Firm), stockholders may vote in favor of or against the proposal or may abstain from voting.

2

Because abstentions are treated as both “present” and “entitled to vote” on a matter, abstaining has the same effect as a vote “against” the proposal. For a discussion of the treatment of “broker non-votes,” see the “Shares Held in Street Name” section of this Proxy Statement.

Because your vote on Proposal 2 (Say on Pay) is advisory in nature, the results will not be binding on the Company, the Board, or the Compensation Committee. However, the Board and the Compensation Committee will review and consider the voting results when making future decisions regarding executive compensation.

The below table summarizes the voting requirements to elect directors and to approve each of the other proposals in the Proxy Statement.

Proposal	Vote Required	Broker Discretionary Voting Allowed	Board of Directors Recommendation
1.  Election of Directors	Plurality of the votes cast	No	FOR each Director Nominee
2.  Advisory Vote to Approve Named Executive Officer Compensation	Holders of a majority in voting power of the shares entitled to vote present in person or by proxy	No	FOR
3.  Ratification of the Appointment of Independent Registered Public Accounting Firm	Holders of a majority in voting power of the shares entitled to vote present in person or by proxy	Yes	FOR

Shares Held in Street Name

If you hold your shares in “street name” as of the close of business on the Record Date, you may gain access to the meeting by following the instructions in the voting instruction card provided by your broker, bank or other nominee. Note that the deadline for voting through your broker, bank or other nominee will not necessarily correspond to the voting deadline for proxyholders. You may not vote your shares electronically at the Annual Meeting unless you receive a valid proxy from your brokerage firm, bank, broker dealer or other nominee holder.

A “broker non-vote” occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner. On routine matters, brokers have the discretion to vote shares held in “street name” – a term that means the shares are held in the name of the broker on behalf of its customer, the beneficial owner. If your shares are held in “street name” by a broker and you wish to vote on the proposal to elect the directors (Proposal 1), the advisory vote to approve Named Executive Officer compensation (Proposal 2), or to act upon any other non-routine business that may properly come before the Annual Meeting, you should provide instructions to your broker. Under the rules of the New York Stock Exchange (the “NYSE”), if you do not provide your broker with instructions, your broker generally will only have the authority to vote on the ratification of the appointment of Grant Thornton LLP, as the Company’s independent registered public accounting firm (Proposal 3). All other matters at the Annual Meeting are expected to be non-routine and therefore brokers will not be entitled to vote on a beneficial owner’s behalf without voting instructions or discretionary authority on such matters. Because broker non-votes are outstanding shares that are not entitled to vote on non-routine matters, they will have no effect on the outcome of Proposal 2 and, as noted above, will also have no effect on the outcome of Proposal 1.

Proxy Cards

If you sign and return your proxy card but do not specify how your shares of Common Stock are to be voted, they will be voted: FOR election as a director of each of the nominees named under “Proposal No. 1 –

3

Election of Directors” in this Proxy Statement and listed under Item 1 of the enclosed proxy card; FOR “Proposal No. 2 – Advisory Vote to Approve Named Executive Officer Compensation” in this Proxy Statement and listed under Item 2 of the enclosed proxy card; and FOR “Proposal No. 3 – Ratification of the Appointment of Independent Registered Public Accounting Firm” in this Proxy Statement and listed under Item 3 of the enclosed proxy card. If other matters are properly presented at the Annual Meeting for consideration, the persons named in the proxy will have the discretion to vote on those matters for the stockholder.

As a matter of policy, proxy cards, ballots and voting tabulations that identify individual stockholders are kept confidential by the Company. Such documents are made available only to the inspector of election and personnel associated with processing proxies and tabulating votes at the Annual Meeting. The votes of individual stockholders will not be disclosed except as may be required by applicable law.

Attending the Annual Meeting Virtually

The Annual Meeting will be a completely virtual meeting of stockholders conducted exclusively by a live audio webcast. Only record or beneficial owners of Common Stock as of the Record Date may attend the Annual Meeting, vote their shares and submit online questions.

In order to attend the Annual Meeting, you must register at www.proxydocs.com/SMHI. Upon completing your registration, you will receive further instructions via email, including a unique link that will allow you access to the Annual Meeting and to vote and submit questions during the Annual Meeting. As part of the registration process, you must enter the control number located on your proxy card, or voting instruction card. If you are a beneficial owner of shares registered in the name of a broker, bank or other nominee, you will also need to provide the registered name on your account and the name of your broker, bank or other nominee as part of the registration process.

The Annual Meeting will begin promptly at 9:00 a.m. (EDT), with online check-in beginning at 8:45 a.m. (EDT). Stockholders must use the unique link emailed to them upon completing their registration to access the Annual Meeting.

If you wish to submit a question for the Annual Meeting, you may do so in advance of the meeting at www.proxydocs.com/SMHI or at any point during the Annual Meeting (until the floor is closed to questions).

Revocation of Proxies

A stockholder who so desires may revoke his, her, or its proxy at any time before it is exercised at the Annual Meeting by: (i) providing written notice to the Secretary of the Company; (ii) duly executing a proxy card bearing a date subsequent to that of a previously furnished proxy card; (iii) entering new instructions by Internet or telephone; or (iv) attending the webcast of the Annual Meeting and voting virtually. Attendance at the Annual Meeting will not in itself constitute a revocation of a previously furnished proxy. Stockholders who attend the Annual Meeting need not revoke their proxy (if previously furnished) to vote virtually at the meeting. The Company encourages stockholders that plan to join the Annual Meeting to vote by phone or Internet or to submit a valid proxy card and vote their shares prior to the Annual Meeting. Even after you have voted electronically through the Internet or by telephone or submitted your proxy card, you may change your vote at any time before the proxy is exercised at the Annual Meeting by joining the webcast (see the “Attending the Annual Meeting Virtually” section of this Proxy Statement). If you hold your shares in “street name” and want to revoke your proxy, you will need to follow the instructions of your broker to revoke or change your previous vote (see the “Shares Held in Street Name” section of this Proxy Statement).

Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting to be Held on June 4, 2024

CORPORATE GOVERNANCE

Board Leadership Structure

The Board believes that there is no single organizational model that would be most effective in all circumstances and that it is in the best interests of the Company and its stockholders for the Board to retain the authority to modify its leadership structure to best address the Company’s circumstances from time to time.

The Board believes that the most effective leadership structure for the Company at the present time is to maintain the separate positions of Non-Executive Chairman and Chief Executive Officer. Separating these positions allows the Chief Executive Officer to focus on the full-time job of running the Company’s business, while allowing the Non-Executive Chairman to lead the Board in its fundamental role of providing advice to and independent oversight of management. The Board believes this structure recognizes the time, effort, and energy that the Chief Executive Officer is required to devote to his position in the current business environment, as well as the commitment required to serve as the Company’s Non-Executive Chairman, particularly as the Board’s oversight responsibilities, especially risk oversight, continue to grow and demand more time and attention. The Board also believes that separating the Non-Executive Chairman and Chief Executive Officer positions provides enhanced independent leadership and oversight for the Company, management and the Board.

In addition to the role that the Non-Executive Chairman has with regard to the Board, the chairperson of each of the three independent key committees of the Board (Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee) and each individual director is responsible for helping ensure that meeting agendas are appropriate and that sufficient time and information are available to address issues that the directors believe are significant and warrant their attention. Each director has the opportunity and ability to request agenda items, information, and additional meetings of the Board or of the independent directors.

The Board has adopted significant processes designed to support the Board’s capacity for objective judgment, including executive sessions of the independent directors at Board meetings at which no employees are present, independent evaluation of, and communication with, members of senior management, and rigorous self-evaluation of the Board, its committees, and its leadership. These and other critical governance processes are reflected in the Corporate Governance Guidelines and the various Committee Charters that are available on the Company’s website at www.seacormarine.com by navigating to “Investors,” and clicking “Corporate Governance.” The Company’s website and the information contained therein or connected thereto shall not be deemed to be incorporated into this Proxy Statement. The Board has also provided mechanisms for stockholders to communicate in writing with the Non-Executive Chairman of the Board, with the non-management and/or independent directors, and with the full Board on matters of significance. These processes are outlined in the “Communications with the Board or Independent Directors” section of this Proxy Statement.

Board of Directors and Director Independence

The business and affairs of the Company are managed under the direction of the Board. The Company’s Third Amended and Restated By-Laws (the “By-Laws”) provide that the Board will consist of not less than five and not more than twelve directors. In 2023, the Board consisted of five (5) directors.

During 2023, the Board held six meetings. The Board also acted pursuant to unanimous written consent on six other occasions. Each of the current directors attended at least 75% of the combined total meetings of the full Board and the committees on which they served during 2023. Although the Company does not have a formal policy governing director attendance at the annual meeting of stockholders, attendance is strongly encouraged and each member of our Board with the exception of Alfredo Miguel, attended the Company’s 2023 annual meeting of stockholders. All members of our Board plan to virtually attend the Annual Meeting.

6

Our Board consults with legal counsel to ensure that the Board’s independence determinations are consistent with all relevant securities and other laws and regulations regarding director independence, including the requirements of the New York Stock Exchange. To assist in the Board’s independence determinations, each director completed materials designed to identify any relationships that could affect the director’s independence. In addition, through discussions among our directors, a subjective analysis of independence is undertaken by the Nominating and Corporate Governance Committee. Our Board is currently composed of a majority of independent directors, with the Board having made the affirmative determination that each of Mr. Andrew R. Morse, Mr. R. Christopher Regan and Ms. Julie Persily, is independent as such term is defined by the applicable rules and regulations of the NYSE. Additionally, each of these directors meets the categorical standards for independence established by the Board (the “SEACOR Marine Categorical Standards”). A copy of the SEACOR Marine Categorical Standards is available on the Company’s website at www.seacormarine.com by navigating to “Investors,” and clicking “Corporate Governance” (entitled “Director Independence Standards”).

The schedule of Board meetings is made available to directors in advance along with the agenda for each meeting so that they may review and request changes. Directors also have unrestricted access to management at all times and regularly communicate informally with management on an assortment of topics. The Company’s Chief Executive Officer hosts a monthly conference call with the directors and other senior management to discuss recent business developments and other matters.

Carlyle Board Rights

On October 5, 2022, the Company and certain funds affiliated with The Carlyle Group Inc. (“Carlyle,” and such investors, the “Carlyle Investors”) entered into two agreements pursuant to which the Company issued the Carlyle Investors (i) $90.0 million in aggregate principal amount of the Company’s 8.0% / 9.5% Senior PIK Toggle Notes due 2026 (the “Guaranteed Notes”), and (ii) $35.0 million aggregate principal amount of the Company’s 4.25% Convertible Senior Notes due 2026 (the “New Convertible Notes”) in exchange for all $125.0 million in aggregate principal amount of the Company’s existing convertible notes (the “Old Convertible Notes”) (the “Exchange Transaction”). The New Convertible Notes were issued pursuant to the Exchange Agreement (Convertible Notes) among the Company, as issuer, and the Carlyle Investors (the “Convertible Notes Exchange Agreement”).

Consistent with the requirements of the documents governing the Old Convertible Notes, the Convertible Notes Exchange Agreement requires the Company to use reasonable best efforts, subject to its directors’ fiduciary duties, to cause a person designated by Carlyle (if Carlyle so chooses) to be appointed as a director on the Board, if Carlyle, solely as a result of the conversion of the Convertible Notes for shares of our Common Stock, collectively owns or continues to own (or would own upon conversion), 10.0% or more of our outstanding shares of Common Stock on a fully diluted basis (the “Board Nomination Right”). The Board Nomination Right was previously contained in the note purchase agreement (“Note Purchase Agreement”) and the investment agreement (the “Investment Agreement”), by and between the Company and Carlyle in connection with the issuance of the Old Convertible Notes. Carlyle was also provided a right to appoint a board observer under certain circumstances. A representative of Carlyle observes meetings of the Board pursuant to Carlyle’s observer rights under the Convertible Notes Exchange Agreement. This observation right will terminate at the time Carlyle owns less than the lesser of (i) $50.0 million in aggregate principal amount of New Convertible Notes and Guaranteed Notes, and (ii) New Convertible Notes and Guaranteed Notes and warrants representing 5.0% of the Common Stock outstanding on a fully diluted basis, assuming the conversion of all such New Convertible Notes held by Carlyle and the exercise of the warrants.

Carlyle has not exercised its right to nominate a board member since April 2018. Carlyle has exercised this observer right with respect to most board meetings during 2023 and we expect they will continue to do so as long as they maintain that right under the Convertible Notes Exchange Agreement.

Executive Sessions

Directors meet at regularly scheduled executive sessions without any members of management present to discuss issues relating to management performance and any other issue that may involve a potential

7

conflict of interest with management. Executive sessions are generally presided over by the Company’s Non-Executive Chairman, Mr. Morse, who is responsible for:

• chairing executive sessions of Board meetings, which include meetings to evaluate and review the performance of the Chief Executive Officer;

• conferring with the Chief Executive Officer and serving as a liaison between the independent directors (who also have direct and complete access to the Chief Executive Officer) and the Chief Executive Officer, including providing the Chief Executive Officer with feedback from executive sessions of the independent directors;

• advising members of management and members of the Board, where necessary, with respect to the Board’s strategic review of operations and significant transactions;

• acting on behalf of the Company to communicate corporate governance matters to the Company’s stockholders; and

• together with the Nominating and Corporate Governance Committee, presiding over the Board’s self-evaluation.

Committees of the Board of Directors

The Board has established the following committees, each of which operates under a written charter that is available on the Company’s website at www.seacormarine.com by navigating to “Investors,” and clicking “Corporate Governance.”

Audit Committee

The Audit Committee is composed of three members: Mr. Morse, Mr. Regan and Ms. Persily. Mr. Morse, Mr. Regan and Ms. Persily have all served since the last annual meeting of stockholders and continue to serve on the Audit Committee. Mr. Morse is the Audit Committee Chairman. The Board has determined that Mr. Morse is an “audit committee financial expert” for purposes of the rules of the United States (“U.S.”) Securities and Exchange Commission (“SEC”). In reaching this determination, the Board considered, among other things, Mr. Morse’s experience as an investment banker for over 25 years, in addition to his other experience that is described elsewhere in this Proxy Statement. In addition, the Board determined that each member of the Audit Committee is financially literate, as required under the NYSE standards, and is considered independent, as defined by the rules of the NYSE applicable to Audit Committee members, Section 10A(m)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and in accordance with the SEACOR Marine Categorical Standards. In accordance with the NYSE Listed Company Manual Rule 303A.07, which stipulates that if an audit committee member simultaneously serves on the audit committees of more than three public companies, the Board must determine whether such simultaneous service would not impair the ability of such member to effectively serve on the Audit Committee. Ms. Persily currently serves on a total of four public company audit committees including the Audit Committee of the Company. The Board has determined that the simultaneous service on four public company audit committees by Ms. Persily does not impair her ability to effectively serve on the Audit Committee. The Audit Committee is expected to meet at least quarterly. The Audit Committee met four times during 2023 and acted pursuant to unanimous written consent on one other occasion.

Committee Function. The Audit Committee assists the Board in fulfilling its responsibility to oversee, among other things:

• the conduct and integrity of management’s execution of the Company’s financial reporting process, including the reporting of any material events, transactions, changes in accounting estimates or changes in important accounting principles and any significant issues as to adequacy of internal controls;

• the selection, performance, qualifications and compensation of the Company’s independent registered public accounting firm (including its independence), their conduct of their annual audit and their engagement for any other services;

8

• the review of the financial reports and other financial information provided by the Company to any governmental or regulatory body, the public or other users thereof;

• the Company’s systems of internal accounting and financial and disclosure controls and procedures, and the annual independent audit of the Company’s financial statements;

• risk management and controls, which includes assisting management with identifying and monitoring risks, developing effective strategies to mitigate risk, and incorporating procedures into its strategic decision-making (and reporting developments related thereto to the Board);

• the processes for handling complaints relating to accounting, internal accounting controls and auditing matters;

• the Company’s legal and regulatory compliance;

• the annual self-evaluation of the Board’s performance;

• the Company’s code of ethics as established by management and the Board; and

• the preparation of the Audit Committee report required by the SEC rules to be included in the Company’s annual proxy statement.

The Audit Committee’s role is one of oversight. Management is responsible for preparing the Company’s financial statements and the independent registered public accounting firm is responsible for auditing those financial statements. Management has more time, knowledge and detailed information about the Company than do Audit Committee members. Consequently, in carrying out its oversight responsibilities, the Audit Committee will not provide any expert or special assurance as to the Company’s financial statements or any professional certification as to the independent registered public accounting firm’s work.

Compensation Committee

The Compensation Committee is composed of three members: Mr. Regan, Mr. Morse and Ms. Persily. Mr. Regan, Mr. Morse and Ms. Persily have all served since the last annual meeting of stockholders and continue to serve on the Compensation Committee. Mr. Regan is the Compensation Committee Chairman. The Board has determined that each member of the Compensation Committee is independent, as defined by the rules of the NYSE applicable to Compensation Committee members and in accordance with the SEACOR Marine Categorical Standards. The Compensation Committee met four times during 2023 and acted pursuant to unanimous written consent on one other occasion.

Committee Function. Pursuant to its charter, the Compensation Committee is primarily responsible for, among other things:

• reviewing and evaluating all of the Company’s compensation practices;

• reviewing and approving the compensation of the Chief Executive Officer and the Company’s other executive officers;

• reviewing director compensation at least annually, in consultation with the Nominating and Corporate Governance Committee when appropriate, and recommending any changes to the Board for approval;

• reviewing and assessing any potential risks associated with the Company’s compensation programs and procedures;

• reviewing and making recommendations to the Board for the approval of changes in incentive compensation and equity-based compensation plans; and

• conducting an annual self-evaluation of its own performance, including its effectiveness and compliance with its charter.

9

The Chairman of the Compensation Committee sets the agenda for the meetings of the Compensation Committee with the input from the Company’s executive management. Members of executive management may also attend meetings, if requested. At each meeting, the Compensation Committee has the opportunity to meet in executive session. When the Compensation Committee acts without the approval of the full Board, the Chairman of the Compensation Committee reports the Compensation Committee’s actions regarding compensation to the full Board. The Compensation Committee has the sole authority to retain, obtain the advice of, and terminate, any compensation consultants, independent legal counsel or other advisors to assist the Compensation Committee in its discharge of its duties and responsibilities, including the evaluation of director or executive officer compensation.

Compensation Committee Interlocks and Insider Participation. None of the current members of the Compensation Committee is or ever was an officer or employee of the Company. During 2023, none of the Company’s executive officers served as a director or member of the compensation committee of any other entity whose executive officers serve on the Board or the Compensation Committee.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee is composed of three members: Mr. Regan, Mr. Morse and Ms. Persily. Mr. Regan, Mr. Morse and Ms. Persily have all served since the last annual meeting of stockholders and continue to serve on the Nominating and Corporate Governance Committee. Mr. Regan is the Nominating and Corporate Governance Committee Chairman. The Board has determined that each member of the Nominating and Governance Committee is independent, as defined by the rules of the NYSE and in accordance with the SEACOR Marine Categorical Standards. The Nominating and Corporate Governance Committee met four times during 2023 and acted pursuant to unanimous written consent on one other occasion.

Committee Function. The Nominating and Corporate Governance Committee assists the Board with:

• identifying, screening and reviewing individuals qualified to serve as directors and recommending to the Board candidates for election at the Company’s annual meeting of stockholders and to fill vacancies on the Board;

• developing, recommending and implementing modifications, as appropriate, to the Company’s Corporate Governance Guidelines and policies and procedures for identifying and reviewing candidates for the Board, including policies and procedures relating to candidates for the Board submitted for consideration by stockholders;

• reviewing the composition of the Board as a whole, including whether the Board reflects the appropriate balance of independence, sound judgment, business specialization, technical skills, expertise in cybersecurity and other emerging risks, diversity and other desired qualities;

• reviewing periodically the size of the Board and recommending any appropriate changes;

• overseeing the evaluation of the Board and management;

• recommending changes in director compensation in consultation with the Compensation Committee when appropriate;

• reviewing, on a regular basis, the overall corporate governance of the Company and recommending to the Board improvements when necessary; and

• overseeing the Company’s environmental, social and governance (“ESG”) program and sustainability initiatives and working with the Sustainability Council to ensure the Company’s goals with respect to ESG and sustainability practices are addressed and met.

Selection of Nominees for the Board of Directors. To fulfill its responsibility to recruit and recommend to the full Board nominees for election as directors, the Nominating and Corporate Governance

10

Committee reviews the composition of the full Board at least annually to determine the qualifications and areas of expertise needed to further enhance the composition of the Board and works with management in attracting candidates with those qualifications.

In identifying new director candidates, the Nominating and Corporate Governance Committee seeks advice and names of candidates from Nominating and Corporate Governance Committee members, other members of the Board, members of management and other public and private sources. The Nominating and Corporate Governance Committee, in formulating its recommendation of candidates to the Board, considers each candidate’s personal qualifications and how such personal qualifications effectively address the then-perceived current needs of the Board. The minimum qualifications and criteria for membership on the Board include the following:

• experience investing in and/or guiding complex businesses as an executive leader or as an investment professional within an industry or area of importance to the Company;

• proven judgment and competence, substantial accomplishments, and prior or current association with institutions noted for their excellence;

• complementary professional skills and experience addressing the complex issues facing a multifaceted international organization; and

• an understanding of the Company’s businesses and the environment in which it operates.

The Nominating and Corporate Governance Committee also considers the diversity of the Board as well as potential candidates as to business experiences, educational and professional backgrounds and gender, race and ethnicity in recruiting and recommending candidates for election.

After the Nominating and Corporate Governance Committee completes its evaluation, it presents its recommendations to the Board for consideration and approval. The Nominating and Corporate Governance Committee has the power to retain outside counsel, director search and recruitment consultants or other experts and will receive from the Company adequate funding, as determined by the Nominating and Corporate Governance Committee, for payment of reasonable compensation to such advisors.

Having evaluated the Board candidates set forth under Proposal No. 1 pursuant to these processes and criteria, the Nominating and Corporate Governance Committee recommended, and the Board determined to nominate, each of the persons named in the “Standing Director Nominees” section of this Proxy Statement for election.

Stockholder Recommendations. The Nominating and Corporate Governance Committee will consider director candidates suggested by the Company’s stockholders provided that the recommendations are made in accordance with the same procedures required under the By-Laws for nomination of directors by stockholders. For instance, stockholder nominations must comply with the notice provisions described under the “Stockholder Proposals for the 2025 Annual Meeting” section of this Proxy Statement. Stockholder nominations that comply with these procedures and that meet the criteria outlined therein will receive the same consideration that the Nominating and Corporate Governance Committee’s nominees receive. There have been no changes to these procedures over the last fiscal year. The Company will report any material change to this procedure in an appropriate filing with the SEC and will make any such changes available promptly on the “SEC Filings” section of the Company’s website at www.seacormarine.com.

Communications with the Board or Independent Directors

Stockholders or interested parties who wish to communicate with the Board, the Non-Executive Chairman and/or independent directors, may do so by writing in care of the Company’s Corporate Secretary, indicating by title or name to whom correspondence should be directed. Correspondence should be sent to SEACOR Marine Holdings Inc., Attn: Corporate Secretary, 12121 Wickchester Lane, Suite 500, Houston, Texas 77079 or by email to corporatesecretary@seacormarine.com. The independent directors have

11

established procedures for handling communications from stockholders of the Company and directed the Corporate Secretary to act as their agent in processing any communications received. All communications that relate to matters that are within the scope of the responsibilities of the Board and its committees will be forwarded to the Non-Executive Chairman and independent directors. Communications that relate to matters that are within the responsibility of one of the Board committees will be forwarded to the chairperson of the appropriate committee. Communications that relate to ordinary business matters that are not within the scope of the Board’s responsibilities will be sent to the appropriate executive. Solicitations, junk mail and obviously frivolous or inappropriate communications will not be forwarded, but will be made available to any director who wishes to review them.

The Audit Committee has established procedures for (i) the receipt, retention, and treatment of complaints, reports and concerns regarding accounting, internal accounting controls, or auditing matters, and (ii) the confidential, anonymous submission of complaints, reports and concerns by employees regarding questionable accounting or auditing matters. These procedures are available on the Company’s website, at www.seacormarine.com by navigating to “Investors,” and clicking “Corporate Governance” (entitled “Procedures for Addressing Complaints”). Such complaints, reports or concerns may be communicated to the Company’s General Counsel or the Chairman of the Audit Committee through a toll-free hotline at +1 (844) 359-7729 or through an internet based reporting tool provided by NAVEX Global (www.seacormarine.ethicspoint.com), each of which ensures that the communications are made on an anonymous and confidential basis. Complaints received are logged by the General Counsel, communicated to the Chairman of the Audit Committee and then investigated by the General Counsel under the supervision of the Audit Committee, unless the Audit Committee determines a different approach is required. These procedures permit the retention of counsel, accountants and consultants to help with such investigations. In accordance with Section 806 of the Sarbanes-Oxley Act of 2002, as amended (the “Sarbanes-Oxley Act”), these procedures prohibit the Company from retaliating against any person who, in good faith, submits an accounting or auditing complaint, report or concern or provides assistance in the investigation or resolution of such matters.

Risk Oversight

The Company’s business, financial condition, results of operations, cash flows and prospects can be adversely affected by risk. The management of risk is central to the success of the Company and requires the involvement of the Board, officers, employees, and internal and independent auditors, all of whom are entrusted to develop a balanced and prudent approach to risk.

The Company has developed and implemented operational controls designed to identify and mitigate risk associated with its financial decisions, operations, legal compliance, business development, changing business conditions, executive compensation, ESG initiatives, cybersecurity and information technology systems. The Chief Executive Officer, with the assistance of the Chief Financial Officer, Chief Accounting Officer, General Counsel, Executive Vice Presidents, Senior Vice Presidents, other key officers and external legal counsel, is responsible for, among other risk management measures:

• implementing measures designed to ensure the highest standard of safety for personnel, the environment, information technology systems and property in performing the Company’s operations;

• obtaining appropriate insurance coverage; and

• evaluating and identifying risk related to the Company’s capital structure, as well as compensation programs, after a rigorous assessment of its business activities.

The Board has reviewed and evaluated, and expects to routinely review and evaluate, the Company’s risk profile to ensure that the measures implemented by the Company are adequate to execute and implement the Company’s strategic objectives. Issues related to risk are regularly discussed by the Chief Executive Officer and the rest of the senior management team with members of the Board both through informal communications, such as email, telephone conference and in-person meetings, and during formal Board

12

meetings. Senior management makes formal presentations to the Board regarding risk management issues at least once per year. Our Non-Executive Chairman and certain other Board members are intimately familiar with the risks associated with the types of assets managed and owned by the Company and routinely engage in dialogue with the Chief Executive Officer and appropriate members of senior management regarding such risks. In addition, when the Board reviews particular transactions and initiatives that require Board approval, or that otherwise merit Board involvement, the Board generally includes related risk analysis and mitigation plans among the matters addressed with management. The Board also oversees cybersecurity risks. See the “Cybersecurity Risk Management” section of this Proxy Statement for additional information regarding the Company’s cybersecurity risk management program.

The Audit Committee, together with senior management, works to respond to recommendations from internal and external auditors and supervisory authorities regarding the Company’s compliance with internal controls and disclosure controls and procedures, and other factors that could interfere with the Company’s reporting obligations, as well as the successful implementation of the Company’s strategic plan. The Audit Committee also reviews the adequacy of the Company’s risk management policies and procedures and meets privately with Company employees and the General Counsel to consider recommendations regarding policies related to risk management. In addition, senior management works closely with the General Counsel to facilitate compliance with foreign and domestic laws and regulations. The General Counsel also reports to the Board on Company programs and initiatives that educate employees on these laws, regulations and any updates thereto, and facilitates the Company’s compliance therewith.

The Compensation Committee oversees the Company’s compensation programs and oversees and evaluates risks relating to its compensation programs and human capital management more generally. The General Counsel keeps the Compensation Committee updated on matters relating to retention of key employees, employee satisfaction, team member diversity and related matters.

The Nominating and Corporate Governance Committee oversees the Company’s ESG program and sustainability initiatives, including the Company’s Sustainability Council. See the “ESG and Sustainability Council” section of this Proxy Statement for additional information regarding the Company’s sustainability initiatives, including the publication of the Sustainability Council’s Inaugural Sustainability Report.

The Board believes that senior management’s significant involvement in risk management and mitigation, combined with Board, Audit Committee and Nominating and Corporate Governance Committee oversight, enables the Company to properly and comprehensively assess risk from both an enterprise-wide and divisional perspective, thereby managing and observing the most substantive risks at each level within the Company.

Cybersecurity Risk Management

Senior management meets periodically with our Board to assess cybersecurity risks and to evaluate the status of our cybersecurity efforts. These efforts are led by our director of technology, who reports directly to our Chief Financial Officer. To address cyber risks, the Company maintains a global set of security policies and standards and regularly evaluates response readiness, disaster recovery or business continuity considerations. In addition, all employees receive annual cybersecurity and phishing training. Our cybersecurity team also consults with industry peers and engages third parties as needed to assess areas of risk as well as the overall maturity of our cybersecurity program.

Corporate Governance Guidelines and Code of Business Conduct and Ethics

The Board has adopted a set of Corporate Governance Guidelines, a Code of Business Conduct and Ethics and a Supplemental Code of Ethics. A copy of each of these documents, along with the charters of each of the committees described above, is available on the Company’s website at www.seacormarine.com by navigating to “Investors,” and clicking “Corporate Governance,” and is also available to stockholders in print without charge upon written request to the Company’s Investor Relations Department, 12121 Wickchester Lane, Suite 500, Houston, Texas 77079.

13

The Corporate Governance Guidelines address areas such as director responsibilities and qualifications, director compensation, management succession, board committees and annual self-evaluation. The Code of Business Conduct and Ethics is applicable to the Company’s directors, officers and employees and the Supplemental Code of Ethics is applicable to the Company’s Chairman, the Company’s Chief Executive Officer, the Chief Financial Officer and other senior financial officers. The Company will disclose future amendments to, or waivers from, certain provisions of the Supplemental Code of Ethics on its website within two business days following the date of such amendment or waiver.

ESG and Sustainability Council

The Company’s ESG program and sustainability initiatives are overseen by its Sustainability Council, which was formed in September, 2020. The Sustainability Council is an internal committee that reports to the Nominating and Corporate Governance Committee and includes senior executives, operational heads, and safety and health, compliance, and human resources professionals, all led by the Company’s Chief Executive Officer. The Sustainability Council collaborates and drives initiatives on all matters related to sustainability, as well as environmental, social and governance practices, including, but not limited to environmental protection, clean energy technology, social responsibility, stakeholder engagement, health and safety, and community empowerment. Together with the Nominating and Corporate Governance Committee, the Sustainability Council helps establish ESG and sustainability goals and integrate them into strategic and tactical business activities across the Company to contribute to risk management and long-term value for all stakeholders.

The Sustainability Council biennially publishes a Sustainability Report documenting the Company’s achievements in three areas: commitment to employees including safety, well-being and maintaining a culture of diversity, equity and inclusion, commitment to reducing carbon emissions and waste across its operations, and commitment to act responsibly as a global citizen. The Company is aligning its operations with the following principles and ESG frameworks: the United Nations Sustainable Development Goals, the Paris Agreement, the Sustainable Accounting Standards Board (Oil & Gas – Services Standard metrics), the Task Force on Climate-Related Financial Disclosures, the Global Reporting Initiative, and the United Nations Global Compact – Sustainable Ocean Principles.

Environmental Sustainability: We recognize and are preparing for the dual challenges of the energy transition and climate change. Our Company is continually adapting its business to adjust to the changing landscape and has increased its focus on reducing fuel consumption and carbon emissions, supporting alternative energy sources and using new technologies to increase the sustainability of our operations and reduce environmental impacts. We are leveraging technology to move the sector forward towards more environmentally friendly processes, leaning into hybrid power solutions and other technologies. We are a pioneer in the use of hybrid power technology, a solution that reduces fuel consumption and emissions by up to 20%, and as of April 1, 2024 we have equipped seven of our twenty-one owned platform supply vessels (“PSVs”) with hybrid battery power systems. Additionally, we have committed to acquire four additional hybrid power systems that will be installed on four of our PSVs, with completion anticipated in 2025. As an industry leader, we are encouraged by the International Maritime Organization’s (“IMO”) strategy on the reduction of greenhouse gases (“GHG”) in international shipping and lowering emissions overall. We continue to evaluate and improve our operational efficiencies across our organization, reduce our fuel consumption and carbon intensity, and ensure compliance with emissions-related regulatory demands.

We are also committed to improving ocean health through pollution prevention and ballast water management, and are reducing the amount of waste produced by our operations to minimize our environmental impact. Our vessels are in full compliance with all laws and regulations with respect to oil spill prevention, and are fully compliant with the current IMO Ballast Water Management Convention (“IMO BWM Convention”). Since 2020, we have been focused on, and continue to explore, initiatives to reduce waste both in our shoreside operations and on board our vessels, including initiatives related to reducing water consumption, plastic waste, lubricant waste, cleaning product waste, office and paper waste, food waste and vessel recycling. The initiatives span our entire business.

Standing Director Nominees

Andrew R. Morse has been a member of the Board since his appointment in May 2017 and has served as Non-Executive Chairman of the Board since June 2021. Mr. Morse served on the SEACOR Holdings board of directors from June 1998 to May 2017. Mr. Morse has been a managing director and senior portfolio manager of Morse, Towey and White, a wealth management unit of High Tower Advisors Inc., a Chicago-based firm of investment advisors since July 31, 2010. In addition, Mr. Morse served on the board of directors and on the audit committee of High Tower Advisors Inc. from July 31, 2010, until January 2018. Mr. Morse was a managing director and senior portfolio manager of UBS Financial Services, Inc., from October 2001 until July 2010.

Mr. Morse sits on numerous philanthropic boards and is treasurer of the American Committee of the Weizmann Institute of Science. Mr. Morse served as a director of Seabulk International, Inc., both before and following its merger with SEACOR Holdings in July 2005 until March 2006. In December 2015, Mr. Morse became a member of the board of managers of KGP Realty, a private residential property management company.

We believe that Mr. Morse’s deep experience in wealth management and corporate finance provides a valuable resource to the Board, the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee. Mr. Morse’s finance experience through advising high net worth individuals and investment entities adds a valuable perspective to the Board. In addition, foreign governments have sought his experience on international corporate finance with respect to issues such as complex energy crisis management and other significant matters of public policy related to our business.

John Gellert has served as the Company’s President and Chief Executive Officer and as a member of the Board since June 1, 2017. Prior to the spin-off of the Company from SEACOR Holdings on June 1, 2017 (the “Spin-off”), Mr. Gellert served as the co-chief operating officer of SEACOR Holdings since February 23, 2015, and president of SEACOR Holdings’ Offshore Marine Services segment since July 2005. Mr. Gellert also held various financial, analytical, chartering and marketing roles with SEACOR Holdings since June 1992. Mr. Gellert is an officer and director of certain Company subsidiaries.

15

directors of Offshore Marine Service Association, a member of the executive council at Cohesive Capital Management, L.P., and previously served as president of the National Ocean Industries Association. Mr. Gellert graduated from Harvard College.

We believe that as the Company’s Chief Executive Officer, Mr. Gellert provides valuable insight to the Board on the Company’s day-to-day operations. In addition, Mr. Gellert’s long tenure with the Company allows him to provide valuable insight to the Board about the competitive dynamics of our industry.

R. Christopher Regan has been a member of the Board since his appointment in May 2017. Mr. Regan served on the SEACOR Holdings board of directors from September 7, 2005 to May 2017. Mr. Regan is co-founder and, since March 2002, managing director, of The Chartis Group, a management consultancy group offering strategic, operational, risk management, governance and compliance advice to U.S. healthcare providers, suppliers and payers. Prior to co-founding The Chartis Group in 2001, Mr. Regan served from March 2001 to December 2001 as president of H-Works, a healthcare management consulting firm and a division of The Advisory Board Company. From January 2000 through December 2000, Mr. Regan served as senior vice president of Channelpoint, Inc., a healthcare information services company. Mr. Regan also serves as a trustee of Hamilton College.

We believe that Mr. Regan’s experience providing advice regarding business valuations, risk management, financial governance and compliance adds to the Board’s breadth of experience. This knowledge also provides significant value to the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee.

Julie Persily has been a member of the Board since her appointment in April 2018. Since 2013, Ms. Persily has served on the board of directors of Investcorp Credit Management BDC, Inc., a NASDAQ listed business development company that invests in middle market companies, and as a member of its audit and nominating committees and as chair of its compensation and valuation committees.

Since 2023, Ms. Persily has served on the board of directors of StepStone Private Credit Fund LLC, a non-exchange traded business development company that invests in various credit-related strategies, and as a member of its audit and nominating and corporate governance committees. Ms. Persily has a deep breadth of experience in the finance and capital market industries, having held various roles at Citigroup for nearly 10 years, including serving as the co-head of Citigroup’s leveraged finance group for over two years and head of acquisition finance prior thereto. Ms. Persily also formerly served as co-head of Leveraged Finance and Capital Markets at Nomura Securities. Ms. Persily holds a BA in Economics and Psychology from Columbia College and an MBA in Finance and Accounting from Columbia Business School.

We believe Ms. Persily’s experience and relationships in the financial sector, as well as her knowledge and understanding of corporate governance matters, adds to the Board’s deep bench of experience, and serves as an asset to the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee.

Alfredo Miguel Bejos has been a member of the Board since June 11, 2019. Mr. Miguel has been president and chief executive officer of Proyectos Globales de Energía y Servicios CME, S.A. de C.V.

Mr. Miguel is also a member of the Customer Advisory Panel at Bell Helicopter, a leading company in helicopter manufacturing. Mr. Miguel holds a BA from Universidad Iberoamericana.

16

We believe that Mr. Miguel’s industry experience, specifically his extensive experience in the maritime aspects of the international energy and infrastructure sector, as well as his broad knowledge gained from serving on multiple boards of directors in the transportation industry will add a diverse perspective to the Board.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act, and related rules of the SEC require our directors, officers, and persons who own more than 10% of a registered class of our equity securities (collectively the “Reporting Persons”), to file initial statements of beneficial ownership of securities and statements of changes in beneficial ownership of securities with respect to our equity securities with the SEC. All Reporting Persons are required by SEC regulations to furnish us with copies of all Section 16(a) reports that they file. As with many public companies, we provide assistance to our directors and executive officers in making their Section 16(a) filings pursuant to powers of attorney granted by our insiders.

20

To our knowledge, based solely on our review of the copies of Section 16(a) reports provided to us by such Reporting Persons, including those reports that we have filed on behalf of our directors and executive officers pursuant to powers of attorney, or written representations from certain Reporting Persons, we believe that there has been compliance with all Section 16(a) filing requirements applicable to such Reporting Persons with respect to the fiscal year ended December 31, 2023, with the exception of (i) one Form 5 filed by Mr. Regan on January 29, 2024 reporting a disposition by gift of 4,585 shares of Common Stock on December 6, 2023 by Mr. Regan, and (ii) one Form 5 filed by Mr. Gellert on February 13, 2024 reporting a disposition by gift of 12,634 shares of Common Stock on March 7, 2023 by MCG Assets, LLC, of which Mr. Gellert is a manager.

COMPENSATION OF DIRECTORS

The Compensation Committee, in consultation with the Nominating and Corporate Governance Committee, when appropriate, evaluates the status of Board compensation in relation to comparable U.S. companies (in terms of size, business sector, etc.) and reports findings and recommendations to the Board, including recommendations for approval of changes to compensation. Directors who are also employees of the Company receive no remuneration by reason of such directorship and are not compensated for attending meetings of the Board or standing committees thereof.

Non-employee directors are paid an annual cash retainer of $75,000 and such directors are also eligible to participate in the SEACOR Marine Holdings Inc. 2022 Equity Incentive Plan that is administered by the Compensation Committee (the “2022 Plan,” together with any other equity incentive plans of the Company, the “SEACOR Marine Equity Incentive Plans”). Upon the recommendation of the Compensation Committee, beginning in June of 2022, the Board made adjustments to non-employee director compensation to increase the annual cash retainer from $50,000 to $75,000, and all equity grants made to non-employee directors in 2022 were comprised of grants of restricted shares of Common Stock subject to a 1-year vesting period. In 2021 and other prior years, non-employee directors received a portion of their annual equity grants in the form of immediately vested unrestricted shares of Common Stock.

Historically, annual equity awards are granted to non-employee directors in June of each year. To account for the significant volatility in the Company’s stock price, particularly over the last several years, in a way that was equitable to both directors and stockholders alike, for purposes of calculating the number of restricted shares of Common Stock granted to the non-employee directors, the Compensation Committee determined it was appropriate to use a trailing 60-day volume weighted average closing price (“VWAP”) of the Company’s stock price for purposes of calculating the number of restricted stock awards to be granted. A trailing 60-day VWAP of the Company’s stock price was also used for the purpose of calculating the number of restricted shares granted to NEOs in March 2023. Because the Company’s closing stock price on the grant date had increased above the trailing 60-day VWAP of the Company’s stock price used for purposes of the calculation of restricted stock awards to non-employee directors, the number of restricted shares of Common Stock granted to the non-employee directors in respect of their 2023 annual equity grant ended up being higher than it would have been had the closing price on the grant date been used. Use of a trailing 60-day VWAP is intended to smooth out volatility, understanding that, for any given year, the calculation of the number of restricted stock awards may be higher or lower than it would have been had the closing price on the grant date been used.

On June 6, 2023, upon the recommendation of the Compensation Committee, including with respect to the methodology described above for the calculation of the number of equity awards granted, the Board granted each non-employee director an annual equity award with a grant date fair value of $102,355, comprised of 10,912 restricted shares of Common Stock. As Non-Executive Chairman, Mr. Morse was granted an annual equity award with a grant date fair value of $46,328, comprised of 4,939 restricted shares of Common Stock. In addition, the Board determined that each non-employee director serving on a committee of the Board be compensated for such service as follows: (i) each committee member of the Audit Committee was granted an annual equity award with a grant date fair value of $11,584, comprised of 1,235 restricted shares of Common Stock (with the exception of Mr. Morse, who was granted an annual equity award with a grant date fair value of $23,169, comprised of 2,470 restricted shares of Common Stock as the chairperson of the Audit Committee), (ii) each committee member of the Compensation Committee was granted an annual equity award with a grant date fair value of $11,584, comprised of 1,235 restricted shares of Common Stock (with the exception of Mr. Regan, who was granted an annual equity award with a grant date fair value of $23,169, comprised of 2,470 restricted shares of Common Stock as the chairperson of the Compensation Committee), and (iii) each committee member of the Nominating and Corporate Governance Committee was granted an annual equity award with a grant date fair value of $5,797, comprised of restricted 618 shares of Common Stock (with the exception of Mr. Regan, who was granted an annual equity award with a grant date fair value of $11,584, comprised of 1,235 restricted shares of Common Stock as the chairperson of the Nominating and Corporate Governance Committee). The restricted shares of Common Stock vest on the earlier of (i) the date of the 2024 annual meeting of stockholders of the Company, and (ii) June 6, 2024.

COMPENSATION DISCUSSION AND ANALYSIS

The Compensation Discussion and Analysis and the tables that follow provide information regarding the fiscal 2023 compensation program for the following Named Executive Officers (or NEOs) of the Company:

• John Gellert, President and Chief Executive Officer;

• Jesús Llorca, Executive Vice President and Chief Financial Officer;

• Andrew H. Everett II, Senior Vice President, General Counsel and Secretary; and

• Gregory Rossmiller, Senior Vice President and Chief Accounting Officer.

Consideration of “Say on Pay” Vote Results

At the 2023 annual meeting of stockholders of the Company, a non-binding, advisory vote was taken with respect to the compensation of the Company’s Named Executive Officers. Stockholders expressed substantial support for the compensation of the Company’s Named Executive Officers as disclosed in the Company’s 2023 proxy statement, with 96% of the votes cast in favor of the “Say on Pay” advisory resolution approving the Company’s Named Executive Officer compensation. The Compensation Committee considered the results of the 2023 advisory vote and also considered other factors in evaluating the Company’s executive compensation programs as discussed in this Compensation Discussion and Analysis. Ultimately, the Compensation Committee did not make any changes to its 2023 compensation program solely as a result of the 2023 Say on Pay advisory resolution.

Summary of 2023 Compensation Elements

For 2023, the Compensation Committee implemented the following executive compensation practices:

• Three-Year Vesting of Time-Based Equity Awards. A portion of each NEO’s long-term incentive grant for 2023 was delivered in the form of restricted shares that vest ratably over three years, subject to the NEO remaining employed by the Company on the applicable vesting date.

• Performance Restricted Stock Units. A portion of each NEO’s long-term incentive grant for 2023 was delivered in the form of performance restricted stock units (“PRSUs”). These PRSUs consist of five equal tranches, each of which will be earned if and when the closing price of one share of Common Stock equals or exceeds the specified stock price performance goal for such tranche for 60 consecutive trading days during the three-year performance period beginning on the grant date. Earned PRSUs (if any) will not be settled until the third anniversary of the grant date, subject to the executive remaining employed by the Company on such date.

• Deferred 40% of Annual Bonuses. 40% of each NEO’s annual bonus is deferred to subsequent years, with 20% of bonuses awarded in respect of 2023 to be paid in the first quarter of 2025 and the remaining 20% to be paid in the first quarter of 2026, subject in each case to the continued employment of the NEO. The remaining 60% was paid in March 2024.

• Clawback Policy. The Company adopted a clawback policy in accordance with the requirements of the NYSE.

• No Tax Gross-ups. The Company does not have any contract or agreement with any NEO that provides for a tax gross-up payment, including those related to change in control payments subject to Sections 280G and 4999 of the Internal Revenue Code of 1986, as amended.

• Double-Trigger / Performance Vesting. Time-based awards under the SEACOR Marine Equity Incentive Plans contain a so-called “double-trigger” vesting provision, which generally provides that awards will not

25

be accelerated upon a change in control of the Company if (i) an acquiror replaces or substitutes outstanding awards in accordance with the requirements of the SEACOR Marine Equity Incentive Plans, and (ii) a participant holding the replacement or substitute award is not involuntarily terminated within two years following the change in control. The award agreements for performance-based awards under the SEACOR Marine Equity Incentive Plans generally provide that, in the event of a change in control of the Company that occurs prior to the end of the completion of a three-year performance period, (i) any PRSUs that have been earned based on stock price performance (as measured during such performance period but prior to the change in control) will become vested as of the change in control, and (ii) any other PRSUs will be eligible to vest upon the change in control based on the value of the per share consideration received by the Company’s shareholders in relation to the applicable share price hurdles, with any PRSUs that do not become vested based on the foregoing being forfeited for no consideration.

• Restrictions on Hedging or Pledging NEOs. The Company has adopted policies restricting hedging and pledging of Company securities by our NEOs.

• No Change in Control Agreements with NEOs. Although the Executive Employment Agreements (described below) contain double-trigger severance protections in connection with a change in control, we do not maintain standalone change in control agreements with our NEOs.

Executive Compensation Philosophy and Objectives

The Compensation Committee’s compensation philosophy is that subjective consideration of the different elements of performance is necessary to provide the flexibility to make appropriate compensation decisions without solely relying on the use of formulas or benchmarking. Consequently, the Compensation Committee believes it is in the Company’s best interest to conduct its own research regarding executive compensation, which includes a review of executive compensation at companies with similar business lines to that of the Company and a review of compensation at other entities that compete with the Company to employ executives with skills and specialties similar to those possessed by the Company’s executives.

Oversight of Compensation Program

The Compensation Committee is responsible for overseeing our executive compensation programs. See the “Role of Compensation Committee” section of this Proxy Statement for more information on the role and responsibilities of the Compensation Committee.

Market Information

The Compensation Committee reviews reports on executive compensation trends issued by respected publications, and compiles compensation information through Equilar, proxy statements, compensation-related public disclosures, industry trade journals and other sources. In 2023, the Compensation Committee retained Lyons, Benenson & Company Inc. (“LB&Co”) to undertake a review of the peer group to be used for competitive compensation analysis for the executive officers and the independent, non-employee directors of the Company. LB&Co’s assessment included a review of the existing compensation peer group used by the Compensation Committee to understand whether any of the companies included in this group no longer provided appropriate comparison for the Company, as well as an assessment of potential new peers based on relevant industry classifications and selected financial data. Based on the recommendation of LB&Co, the Compensation Committee made the following changes to its compensation peer group: (i) added Diamond Offshore Drilling, Inc., Dorian LPG Ltd., International Seaways, Inc., and Overseas Shipholding Group, Inc., and (ii) removed Archrock, Inc., RPC, Inc., and TETRA Technologies, Inc. Accordingly, the companies with similar lines of operating business considered in connection with the Compensation Committee’s compensation analysis include Bristow Group Inc., Diamond Offshore Drilling, Inc., Dorian LPG Ltd., Dril-Quip, Inc., Forum Energy Technologies, Inc., Gulf Island Fabrication, Inc., Helix Energy Solutions Group, Inc., International Seaways, Inc., Newpark Resources, Inc., Oil States International, Inc., Overseas

26

Shipholding Group, Inc. and Tidewater Inc. The Compensation Committee does not target any particular percentile or comparative level of compensation for executive officers. It does, however, assess the general competitiveness of proposed compensation levels in relation to the compensation paid by peer companies.

Role of Independent Compensation Consultant

Pursuant to its charter, the Compensation Committee is authorized to retain and terminate any compensation consultant, as well as any independent legal, financial or other advisors, as it deems necessary. For fiscal year 2023, the Compensation Committee elected to continue to retain LB&Co as its independent compensation consultant. LB&Co has acted as an independent compensation consultant to the Compensation Committee since 2017 and has assisted the Compensation Committee by providing research and analyses related to peer company data and related market practices as they pertain to executive and independent non-employee director compensation.

Prior to the retention of LB&Co, the Compensation Committee evaluated LB&Co’s independence from management, taking into consideration all relevant factors, including the six independence factors specified in the NYSE listing rules and applicable SEC requirements. The Compensation Committee concluded that LB&Co is independent and that its work for the Compensation Committee does not raise any conflicts of interest.

Role of Executive Officers in Compensation Decisions

In evaluating executive compensation, Mr. Gellert assists the Compensation Committee in reviewing the performance of his direct reports and their progress in meeting individual goals in relation to their peers, their respective scope of responsibility and the entire Company. The Compensation Committee typically meets in the latter part of each year and early the following year, and Mr. Gellert is invited to those meetings in order to help evaluate and recommend compensation for the Named Executive Officers (other than with respect to his own compensation), taking into account the following factors:

• the Company’s corporate transactions, financial results and projections;

• the individual performance of the Company’s executive officers; and

• prevailing conditions in the job market.

Mr. Gellert does not participate in any decisions with respect to his own compensation.

Role of Compensation Committee

In making compensation decisions each year, the Compensation Committee considers the following factors:

• market comparisons for cash and equity compensation;

• the risk of not retaining an individual;

• total compensation levels before and after the recommended compensation amounts;

• compensation summaries for each executive that total the dollar value of all compensation-related programs, including annual salary, annual bonus, long-term compensation, and other benefits; and

• target bonus opportunities included in each executive’s employment agreement.

The Compensation Committee also meets in executive session to consider the above factors for executives and to utilize these factors in evaluating Mr. Gellert’s proposed compensation and performance. Additional meetings of the Compensation Committee are held as appropriate to review and grant equity awards to newly hired employees or to current employees in connection with promotions within the Company.

27

Elements of 2023 Compensation

Annual Base Salary

The annual base salaries paid to the Named Executive Officers reflect the experience and skill required for executing the Company’s business strategy and overseeing its day-to-day operations. For 2023, the annual base salaries of each of Messrs. Gellert, Llorca, Everett and Rossmiller were $600,000, $375,000, $325,000 and $325,000, respectively. There have been no changes to annual base salaries of the Named Executive Officers since January 1, 2022.

Annual Bonus

The Compensation Committee continues to review the compensation practices employed by comparable companies in order to assist it in enhancing the design of an annual bonus program. Given the continued volatility in the Company’s stock price as well as commodity prices supporting the Company’s business, it was not realistic for the Compensation Committee to meaningfully design a formulaic annual bonus program for 2023. Following the end of 2023, the Compensation Committee determined that it was appropriate to award cash bonuses to the Named Executive Officers in respect of 2023 performance, after taking into consideration the following factors: (i) the individual contributions of the Named Executive Officers during 2023, including with respect to strategic initiatives, and (ii) the need to retain the Named Executive Officers given their collective industry knowledge and historical knowledge of the Company generally. After taking these factors into account, in early 2023 the Compensation Committee approved the payment of cash bonuses as follows: $750,000, $625,000, $525,000 and $450,000 for each of Mr. Gellert, Mr. Llorca, Mr. Everett and Mr. Rossmiller, respectively. 60% of such cash bonuses was paid in March 2024, and 20% of such cash bonuses will be paid in the first quarter of 2025 and 2026, respectively, subject in each case to the continued employment of the Named Executive Officer. In the event that an NEO’s employment is terminated without “Cause” or an NEO resigns for “Good Reason” or upon the occurrence of a “Change in Control” (as such terms are defined in the applicable NEO’s employment agreement), then any unpaid portion of the 2023 annual cash bonus will be paid out in connection with such event.

Long-term Incentives

The SEACOR Marine Equity Incentive Plans authorize the Compensation Committee to provide equity-based or other incentive-based compensation for the purpose of attracting and retaining the Company and its affiliates’ directors, employees and certain consultants, and providing those directors, employees and consultants with incentive opportunities and rewards for superior performance. The types of awards under the SEACOR Marine Equity Incentive Plans may include stock options, stock appreciation rights, restricted stock and restricted stock units, performance awards and other stock-based awards.

The Compensation Committee established an equity-based compensation program for the Company in order to align the interests of senior employees with the Company’s long-term growth. In general, equity grants are made on dates previously established by the Compensation Committee and the Company does not time the release of non-public information for the purpose of affecting the value of equity awards.

In March 2023, the Compensation Committee approved restricted stock and PRSU awards to the Named Executive Officers. The Compensation Committee introduced PRSUs to its long-term equity program in 2019 in order to better align the Named Executive Officers’ interests with the Company’s stock price by tying the vesting of such awards directly to stock price appreciation, and the Compensation Committee continued this practice in 2023.

The restricted stock awards vest ratably over three years beginning on March 4, 2024, subject to continued employment on each applicable vesting date, with exceptions for certain involuntary terminations. The PRSUs consist of five equal tranches, each of which will be earned if and when the closing price of one share of Common Stock equals or exceeds the specified stock price performance goal for such tranche for 60 consecutive trading days during the three-year performance period beginning on the grant date, provided that

28

any earned PRSUs will not vest and be settled until the third anniversary of the grant date. In order for earned PRSUs to vest and be settled, the executive must remain employed by the Company on the third anniversary of the grant date, subject to exceptions for certain involuntary termination events that occur prior to the vesting date. The specified stock price performance goals for each tranche are $11.61, $13.21, $14.91, $16.62 and $18.22, respectively. The Compensation Committee did not approve any other equity awards to the Named Executive Officers during 2023.

Pursuant to the applicable award agreements, the restricted stock and PRSU awards vest subject to the executive’s continued employment with the Company on the applicable vesting date, subject to accelerated vesting upon the executive’s death or qualified retirement or upon termination by the Company without “Cause” (including for disability). Upon any such acceleration event, PRSUs that have been earned with respect to the stock price goal(s) will be settled on the third anniversary of the grant date, without regard to the executive’s employment with the Company as of such date.

The grant date fair value of the restricted stock and PRSU awards granted to each Named Executive Officer in 2023 is set forth in the table below:

Named Executive Officer	John Gellert ($)		Jesús Llorca ($)		Andrew H. Everett II ($)		Gregory Rossmiller ($)
Grant Date Fair Value of Restricted Shares		1,517,577		1,222,499		632,342		590,188
Grant Date Fair Value of PRSUs		372,440		300,032		155,177		144,855

In determining the applicable target value of restricted stock and PRSU awards, the Compensation Committee considered, among other factors, prior-year Company and individual performance, employee retention and incentives, and volatility in the Company’s stock price and the impact this volatility has on the tangible value of the NEOs’ equity awards. Given the significant volatility in the Company’s stock price in the months prior to the expected grant date of the 2023 awards, the Compensation Committee determined that it would be appropriate to use a 60-day VWAP of the Company’s stock price for purposes of calculating the number of restricted stock and PRSU awards granted. For example, on the day the March 2023 awards were granted, the closing price of our common stock was $10.37, and the 60-day VWAP was $10.01. Given the Compensation Committee had previously decided to use a 60-day VWAP, the Compensation Committee determined it would not be appropriate to change its methodology based on the increased price on or around the grant date, because the Compensation Committee’s intent when it determined to use a 60-day VWAP was to smooth out potential stock price volatility. The grant date fair values of the Restricted Shares and PRSUs reflect the fact that the number of awards granted was based on a lower stock price (therefore yielding a greater number of Restricted Shares and PRSUs than would have otherwise been granted had the closing stock price on the grant date been used), and this number of shares is then multiplied by the closing stock price on the grant date (or otherwise incorporated into the Monte Carlo simulation with respect to the PRSUs), in order to calculate the grant date fair value from a financial reporting perspective. However, it is important to note that the grant date fair values reported in this Proxy Statement do not necessarily correlate to the value realized by the NEOs, because the value ultimately realized from these awards will be based on (i) satisfaction of the underlying vesting conditions, and (ii) the Company’s stock price when such awards vest.

Performance Results of 2020 PRSUs. On February 8, 2023, the PRSUs granted in 2020 were forfeited and terminated upon determination of the Compensation Committee that none of the stock price performance goals were capable of being satisfied for the required 60 consecutive trading days prior to the last day of the three-year performance period.

Performance Results of 2021 PRSUs. On March 12, 2024, 100% of the PRSUs granted in 2021 were determined to have been achieved based on stock price performance during 2021-2023, and were settled in accordance with their terms.

29

Stock Ownership Guidelines

The Compensation Committee has adopted Stock Ownership Guidelines (the “Guidelines”) for executive officers at the Senior Vice President level or higher. Each executive officer subject to the Guidelines is expected to hold Company stock, including unvested restricted shares, with a value equal to a multiple of his or her annual base salary, as follows:

Officers	Holding Requirement
Chief Executive Officer	5X annual base salary
Executive Vice President	3X annual base salary
Senior Vice President	2X annual base salary

Neither unvested PRSUs nor options count toward satisfaction of the Guidelines. Officers subject to the Guidelines are expected to comply within five years from the date the individual is named to a participating position. As of February 28, 2024, all NEOs have met the stock ownership requirements.

Clawback Policy

The award agreements applicable to any stock options, restricted stock and PRSU awards granted to the Named Executive Officers in years 2017 through 2024 provide that the shares of Common Stock underlying such awards are subject to recoupment under any existing clawback policy or any clawback policy that the Company is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 or other applicable laws.

The Compensation Committee adopted a Clawback Policy intended to comply with the listing requirements of the NYSE. The Clawback Policy requires the Company to clawback erroneously awarded incentive compensation “received” (i.e., earned) by the covered officers during the three fiscal years that precede the date on which the Company determines it is required to prepare a “Big R” or “little r” accounting restatement. The Clawback Policy applies to those current and former officers who are subject to Section 16(a) of the Exchange Act, and applies to incentive-based compensation (i.e., compensation that is earned in whole or in part based on the attainment of financial performance measures). A copy of the Clawback Policy is included as an exhibit in the Company’s 2023 Annual Report on Form 10-K filed with the SEC on February 29, 2024.

Policy Against Pledging and Hedging Company Securities

The Company has adopted policies restricting hedging and pledging of Company securities by our directors, senior officers and employees. The Board has designated Andrew H. Everett II, Senior Vice President, General Counsel and Secretary as the Company’s compliance officer (the “Compliance Officer”). The Compliance Officer, along with other members of the compliance committee designated by the Board (the “Compliance Committee”), will review and either approve or prohibit all proposed trades of Common Stock by directors and executive officers and trades by specified employees outside of trading windows in accordance with the Company’s Insider Trading and Tipping Procedures and Guidelines.

Certain forms of hedging or monetization transactions allow directors, executive officers, employees, and members of the households and dependents of such persons (“Covered Persons”) to continue to own covered securities, but without the full risks and rewards of ownership. When that occurs, Covered Persons may no longer have the same objectives as the Company’s other stockholders. Therefore, Covered Persons are prohibited from engaging in such transactions. Any person wishing to enter into such an arrangement must first pre-clear the proposed transaction with the Compliance Committee. Any request for pre-clearance of a hedging or similar arrangement must be submitted to the Compliance Officer at least two weeks prior to the proposed execution of documents evidencing the proposed transaction and must set forth a justification for the proposed transaction.

Retirement Plans

The Company’s eligible U.S.-based employees may participate in the SEACOR Marine 401(k) Plan, a Company sponsored defined contribution plan (“SEACOR Marine 401(k) Plan”). For 2023, the Company matched employee contributions to the SEACOR Marine 401(k) Plan in the amount of 100% of the first 2.0% of an employee’s eligible compensation that the employee contributed to the SEACOR Marine 401(k) Plan, and 50% of the next 4% of the employee’s eligible compensation that the employee contributed to the SEACOR Marine 401(k) Plan, for a total match of 4% of such employee’s eligible compensation, subject to applicable limitations.

Compensation Risk Assessment

The Compensation Committees believes that the performance goals and incentive program structures generally established under the Company’s executive, annual and long-term incentive programs do not contribute to excessive risk taking by our senior executives or employees. The Company’s compensation programs are balanced, rewarding both short-term and long-term performance, with a balanced focus on stock price, operational and individual performance. The Compensation Committee is actively engaged in establishing compensation programs and payout opportunities, monitoring those systems during the year and using discretion in making rewards, as necessary. As a result of the procedures and practices described above, the Compensation Committee believes that the Company’s compensation policies and practices for its employees do not encourage risk taking that is reasonably likely to have a material adverse effect on the Company.

Equity Grant Practices

The Compensation Committee seeks to approve grants of equity-based awards on or about the same time each year and does not time equity grants to coincide with the release of material non-public information. In recent years, the Compensation Committee has adopted a practice of using a multi-day, VWAP in order to calculate the number of equity-based awards to be made to our NEOs. The Compensation Committee believes that using a VWAP price, rather than a single-day closing price, mitigates the impact that stock volatility could potentially have on the number of awards granted.

Employment Agreements; Change in Control Provisions

Each of the NEOs are party to an employment agreement with the Company, the terms of which are described in the “Employment Contracts/Termination of Employment/Change in Control” section of this Proxy Statement (the “Executive Employment Agreements”). Although the Executive Employment Agreements contain double-trigger severance protections in the event of a “Change in Control,” the Company does not maintain standalone change in control agreements with our NEOs.

Time-based awards under the SEACOR Marine Equity Incentive Plans contain a so-called “double-trigger” vesting provision, which generally provides that awards will not be accelerated upon a change in control of the Company if (i) an acquiror replaces or substitutes outstanding awards in accordance with the requirements of the SEACOR Marine Equity Incentive Plans, and (ii) a participant holding the replacement or substitute award is not involuntarily terminated within two years following the change in control. The award agreements for performance-based awards under the SEACOR Marine Equity Incentive Plans generally provide that, in the event of a change in control of the Company that occurs prior to the end of the completion of a 3-year performance period, (i) any PRSUs that have been earned based on stock price performance (as measured during such performance period but prior to the change in control) will become vested as of the change in control, and (ii) any other PRSUs will be eligible to vest upon the change in control based on the value of the per share consideration received by the Company’s shareholders in relation to the applicable share price hurdles, with any PRSUs that do not become vested based on the foregoing being forfeited for no consideration.

31

Tax Considerations

Section 162(m) of the Internal Revenue Code generally places a $1 million annual deduction limit on compensation paid by public companies to certain executive officers. While the Compensation Committee considers the deductibility of awards as one factor in determining executive compensation, it is not the sole or primary factor considered. The Compensation Committee also looks at other factors in making its decisions and retains the flexibility to award compensation that it determines to be consistent with the goals of our executive compensation program even if the awards are not deductible by the Company for tax purposes.

In order for earned PRSUs to vest and be settled, the executive must remain employed by the Company on the third anniversary of the grant date, subject to accelerated vesting upon the executive’s death or qualified retirement or upon termination by the Company without “Cause” (including for disability). Upon any such acceleration event, PRSUs that have been earned with respect to the stock price goal(s) will be settled on the third anniversary of the grant date, without regard to the executive’s employment with the Company as of such date. The specified stock price performance goals for each tranche are $11.61, $13.21, $14.91, $16.62 and $18.22, respectively.

EMPLOYMENT CONTRACTS/TERMINATION OF EMPLOYMENT/CHANGE IN CONTROL

In connection with a review of the Company’s executive compensation arrangements conducted during 2019, the Compensation Committee approved executive employment agreements for each of Messrs. Gellert, Llorca, Everett and Rossmiller (the “Executive Employment Agreements”), which agreements were executed and became effective on November 5, 2019.

The Executive Employment Agreements set forth the then-current base salary of each of Messrs. Gellert, Llorca, Everett and Rossmiller, and provides that each of them will have a target annual bonus opportunity equal to 100% of the executive’s base salary as in effect from time to time. During 2022, the Compensation Committee, in consultation with LB&Co, the Compensation Committee’s independent compensation consultant, conducted a review of the current cash compensation of the executives. In connection with such review, effective January 1, 2022, the Compensation Committee approved the increase of the base salaries of each of Messrs. Gellert, Llorca, Everett and Rossmiller to $600,000, $375,000, $325,000 and $325,000, respectively. There were no changes to these base salaries in 2023.

Upon a termination of employment by the Company without “Cause” or resignation by the executive for “Good Reason” (as such terms are defined in the Executive Employment Agreements) (each, a “Qualifying Termination”), each executive will be eligible to receive the following severance benefits: (i) a lump sum payment equal to a multiple of the executive’s base salary (2.0x for Mr. Gellert, 1.75x for Mr. Llorca and 1.5x for Messrs. Everett and Rossmiller), (ii) a lump sum amount equal to the average annual cash incentive bonus paid to the executive in respect of the last three calendar years prior to the year in which the executive’s termination of employment occurred (based solely on amounts paid in respect of 2019 and beyond), (iii) a pro-rated annual bonus payable in respect of the year in which the termination occurs, based on actual achievement of the applicable performance goals, and pro-rated based on the number of days the executive was employed by the Company during the calendar year in which the termination occurs, (iv) a lump sum cash payment based on the employer portion of the monthly cost of maintaining health benefits for the executive and his eligible dependents for a period of time following the executive’s termination of employment (24 months for Mr. Gellert, 21 months for Mr. Llorca and 18 months for Messrs. Everett and Rossmiller), and (v) immediate vesting of the unvested portion of certain equity awards, and an extended exercise period for the executive’s outstanding stock options.

If a Qualifying Termination occurs within two years following a “Change in Control” (as such term is defined in the Executive Employment Agreement), the executive will be eligible to receive the same benefits described above, except that the bonus amount described in subsection (ii) will be no less than the executive’s target annual bonus for the year in which the termination occurs.

The executives’ receipt of the severance benefits described above are subject to the executive’s execution and non-revocation of an effective release of claims. The Executive Employment Agreements also provide for certain non-competition, non-solicitation and non-disparagement provisions that apply following a termination of employment. These benefits are in addition to benefits available generally to salaried employees, such as distributions under the Company’s 401(k) savings plan, disability benefits and accrued vacation pay.

(1) Pursuant to the terms of each NEO’s employment agreement, if the NEO’s employment terminates as a result of disability or if the NEO resigns without “Good Reason,” the Company may elect to pay a certain amount of severance in exchange for the NEO agreeing not to compete for a period of six months. As this election is solely in the discretion of the Company, such payments are not included in the table above.

40

(2) As the Company’s equity awards, as well as each NEO’s employment, provide for double-trigger change in control provisions, the dollar amount in this column is based on the assumption that a change in control occurs that is subsequently followed by an involuntary termination of the NEO.

(3) Pursuant to the terms of each NEO’s employment agreement, the dollar amount in this row reflects the amount to paid to the NEO based on a multiple of such NEO’s annual base salary as well as the amount to be paid in respect of a certain period of health benefits.

(4) The Annual Incentive dollar amount in this row reflects (i) pursuant to the terms of each NEO’s employment agreement, the average annual cash bonus of such NEO in respect of 2021, 2022 and 2023, and (ii) the remaining annual installments of the annual cash bonus previously earned in respect of 2022 and 2023 as described above.

(5) As of December 31, 2023, there were no unvested stock options held by any NEO that would accelerate upon the death, disability, qualified retirement or termination without “Cause” of the employee, or, assuming no replacement awards were provided, upon the occurrence of a “Change in Control.”

(6) The dollar amount in this row reflects the closing price of the Company’s Common Stock on December 29, 2023, which was $12.59, for unvested shares of the Company’s Common Stock that would accelerate upon the death, disability, qualified retirement or termination without “Cause” of the employee, or, assuming no replacement awards were provided, upon the occurrence of a “Change in Control.”

(7) The dollar amount in this row reflects the closing price of the Company’s Common Stock on December 29, 2023, which was $12.59, for each PRSU that is earned as of such date based on the specified stock price performance goal of such tranche of PRSUs and that would accelerate upon the death, disability, qualified retirement or termination without “Cause” of the employee or upon the occurrence of a “Change in Control.” As of December 29, 2023, the stock price performance goals of $3.98, $4.53, $5.11, $5.69 and $6.24 were satisfied for each tranche of the PRSUs granted in 2021, and the stock performance goals of $5.02, $5.72, $6.45, $7.19 and $7.88 were satisfied for each tranche of the PRSUs granted in 2022 and no other PRSUs were earned.

PAY VERSUS PERFORMANCE

As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid and the financial performance of the Company.

(1) The dollar amounts reported in column (b) are the amounts of total compensation reported for Mr. Gellert (our Chief Executive Officer (PEO)) for each corresponding year in the “Total” column of the Summary Compensation Table.

(2) The dollar amounts reported in column (c) represent the amount of “compensation actually paid” to Mr. Gellert, as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned by or paid to Mr. Gellert during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to Mr. Gellert’s total compensation for each year to determine the “compensation actually paid”:

Year	Reported Summary Compensation Table Total for PEO ($)		Reported Value of Equity Awards(a) ($)			Equity Award Adjustments(b) ($)		Compensation Actually Paid to PEO ($)
2023		3,253,217		(1,890,017	)		3,651,916		5,015,116

(a) The grant date fair value of equity awards represents the total of the amounts reported in the “Stock Awards” column in the Summary Compensation Table for the applicable year. There were no “Option Awards” granted in respect of the applicable years.

(b) The equity award adjustments for each applicable year include the addition (or subtraction, as applicable) of the following: (i) the year-end fair value of any equity awards granted in the applicable year that are outstanding and unvested as of the end of the year, (ii) the amount of change as of the end of the applicable year (from the end of the prior fiscal year) in fair value of any awards granted in prior years that are outstanding and unvested as of the end of the applicable year, and (iii) for awards granted in prior years that vest in the applicable year, the amount equal to the change as of the vesting date (from the end of the prior fiscal year) in fair value. The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant. The amounts deducted or added in calculating the equity award adjustments are as follows:

43

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

(3) The dollar amounts reported in column (d) represent the average of the amounts reported for the Company’s NEOs as a group (excluding Mr. Gellert) in the “Total” column of the Summary Compensation Table in each applicable year. The names of each of the NEOs included for purposes of calculating the average amounts for each of 2021, 2022 and 2023 were Jesús Llorca, Andrew H. Everett II and Gregory Rossmiller.

(4) The dollar amounts reported in column (e) represent the average amount of “compensation actually paid” to the NEOs as a group (excluding Mr. Gellert), as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual average amount of compensation earned by or paid to these NEOs as a group during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to average total compensation for the NEOs as a group (excluding Mr. Gellert) for each year to determine the “compensation actually paid,” using the same methodology described above in Note (2)(b):

Year	Average Reported Summary Compensation Table Total for Non-PEO NEOs ($)		Average Reported Value of Equity Awards ($)			Average Equity Award Adjustments(a) ($)		Average Compensation Actually Paid to Non-PEO NEOs ($)

2021		411,815		19,061		—		85,356		—			—		516,232

(5) Cumulative total shareholder return is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period. The “measurement period” is the period beginning at the measurement point established by the market close on the last trading day before fiscal year 2021, through and including the end of the fiscal year for which cumulative total shareholder return is being calculated.

(6) The dollar amounts reported represent the amount of net income (loss) reflected in the Company’s audited financial statements for the applicable year.

RELATED PARTY TRANSACTIONS

Related Party Transactions Policy

The Company has established a written policy for the review and approval or ratification of transactions with Related Parties (the “Related Party Transactions Policy”) to assist it in reviewing transactions that exceed the thresholds for disclosure established under Item 404(a) of Regulation S-K promulgated by the SEC (“Related Party Transactions”) involving the Company and its subsidiaries and Related Parties (as defined below). Examples include, among other things, sales, purchases or transfers of real or personal property, use of property or equipment by lease or otherwise, services received or furnished, borrowing or lending (including guarantees), and employment by the Company of an immediate family member of a Related Party or a change in the material terms or conditions of employment of such an individual.

The Related Party Transactions Policy supplements the Company’s other conflict of interest policies set forth in the Company’s Corporate Governance Guidelines, its Code of Business Conduct and Ethics and its other internal procedures. A summary description of the Related Party Transactions Policy is set forth below.

For purposes of the Related Party Transactions Policy, a “Related Party” includes the Company’s directors, director nominees and members of management since the beginning of the Company’s last fiscal year, beneficial owners of 5.0% or more of any class of the Company’s voting securities and members of their respective Immediate Family (as defined in the Related Party Transactions Policy), as well as the Company’s affiliates, investees, trusts for the benefit of employees and other parties with which the Company may deal if one party can control or significantly influence the management or operating policies of the Company.

The Related Party Transactions Policy provides that Related Party Transactions must be approved or ratified by the Audit Committee. The Board has delegated to the Audit Committee the review and, when appropriate, approval or ratification of Related Party Transactions. Upon the presentation of a proposed Related Party Transaction, the Related Party is excused from participation and voting on the matter. In approving, ratifying or rejecting a Transaction, the Audit Committee will consider such information as it deems important to conclude if the transaction is fair and reasonable to the Company.

Whether a Related Party’s interest in a Related Party Transaction is material or not will depend on all facts and circumstances, including whether a reasonable investor would consider the Related Party’s interest in the Related Party Transaction important, together with all other available information, in deciding whether to buy, sell or hold the Company’s securities. In administering this policy, the Board or the relevant committee will be entitled (but not required) to rely upon such determinations of materiality by the Company’s management.

The following factors are taken into consideration in determining whether to approve or ratify a Related Party Transaction with a Related Party:

• the Related Party’s relationship to the Company and interest in the Related Party Transaction;

• the approximate dollar value of the Related Party Transaction;

• the approximate dollar value of the amount of the Related Party’s interest in the Related Party Transaction;

• whether the Related Party Transaction was undertaken in the ordinary course of business of the Company;

• whether the Related Party Transaction is proposed to be, or was, entered into on terms no less favorable to the Company than terms that could have been reached with an unrelated third party;

• the purpose of, and the potential benefits to the Company, of the Related Party Transaction;

• required public disclosures, if any; and

47

• any other information regarding the Related Party Transaction or the Related Party in the context of the proposed related transaction that would be material to investors in light of the particular circumstances.

The following arrangements will not generally give rise to Related Party Transactions with a Related Party for purposes of the Related Party Transactions Policy given their nature, size and/or degree of significance to the Company:

• any employment by the Company of an executive officer of the Company or any of its subsidiaries if the compensation is approved (or recommended to the Board for approval) by the Company’s Compensation Committee;

• any compensation paid to a director if the compensation is consistent with the Company’s director compensation policies and is required to be reported in the Company’s proxy statement under Item 402 of Regulation S-K; and

• any transaction where the Related Party’s interest arises solely from the ownership of the Company’s Common Stock and all holders of the Company’s Common Stock received the same benefit on a pro rata basis (e.g., dividends).

Transactions with Carlyle

On October 5, 2022, the Company and certain funds affiliated with The Carlyle Group Inc. (the “Carlyle Investors”) entered into two agreements pursuant to which the Company issued the Carlyle Investors (i) $90.0 million in aggregate principal amount of the Company’s 8.0% / 9.5% Senior PIK Toggle Notes due 2026 (the “Guaranteed Notes”), and (ii) $35.0 million aggregate principal amount of the Company’s 4.25% Convertible Senior Notes due 2026 (the “New Convertible Notes”) in exchange for all $125.0 million in aggregate principal amount of the Company’s convertible senior notes due 2023 (the “Old Convertible Notes”) outstanding (the “Exchange Transaction”).

Consistent with the requirements of the documents governing the Old Convertible Notes, the Company remains required to use reasonable best efforts, subject to its directors’ fiduciary duties, to cause a person designated by Carlyle (if Carlyle so chooses) to be appointed as a director on the Board, if Carlyle, solely as a result of the conversion of the Convertible Notes for shares of our Common Stock, collectively owns or continues to own (or would own upon conversion), 10.0% or more of our outstanding shares of Common Stock on a fully diluted basis (the “Board Nomination Right”). The Board Nomination Right was previously contained in the note purchase agreement (“Note Purchase Agreement”) and the investment agreement (the “Investment Agreement”), by and between the Company and Carlyle in connection with the issuance of the Old Convertible Notes. Carlyle has not exercised its Board Nomination Right since 2018. Carlyle was also provided a right to appoint a board observer under certain circumstances. A representative of Carlyle observes meetings of the Board pursuant to Carlyle’s observer rights under the Convertible Notes Exchange Agreement. This observation right will terminate at the time Carlyle owns less than the lesser of (i) $50.0 million in aggregate principal amount of New Convertible Notes and Guaranteed Notes, and (ii) New Convertible Notes and Guaranteed Notes and warrants to purchase Common Stock at an exercise price of $0.01 per share (“Warrants”) representing 5.0% of the Common Stock outstanding on a fully diluted basis, assuming the conversion of all such New Convertible Notes held by Carlyle and the exercise of the Warrants. Carlyle has exercised this observer right with respect to most board meetings during 2023 and we expect they will continue to do so as long as they maintain that right under the Convertible Notes Exchange Agreement.

During 2023, the Carlyle Investors exercised 135,150 Warrants. As of December 31, 2023, the Carlyle Investors had 1,304,333 outstanding Warrants.

Transactions with CME

Mr. Alfredo Miguel Bejos, a Director of the Company, currently serves as President and Chief Executive Officer of Proyectos Globales de Energía y Servicios CME, S.A. de C.V. (“CME”). In accordance with the Related Transaction Policy, the Audit Committee has adopted guidelines for addressing ongoing CME-related transactions.

48

Prior to the consummation of the Framework Agreement Transactions described below, the Company participated in a variety of joint ventures with CME, including Mantenimiento Express Maritimo, S.A.P.I. de C.V. (“MexMar”), Offshore Vessels Holding, S.A.P.I. de C.V. (“OVH”) and SEACOR Marlin LLC. The joint venture agreements for each of these joint ventures were negotiated at arms-length in the ordinary course of business. Each of MexMar, OVH and SEACOR Marlin LLC was a joint venture company that was 49% owned by a wholly-owned subsidiary of the Company and 51% owned by subsidiaries of CME.

On September 29, 2022, the Company and certain of its subsidiaries, on the one hand, and Operadora de Transportes Marítimos, S.A. de C.V. (“OTM”), CME Drillship Holdings DAC (“CME Ireland”), and OVH, on the other hand, entered into the Framework Agreement (the “Framework Agreement”). OTM and CME Ireland are affiliates of CME. Prior to the closing of the Framework Agreement Transactions, the Company owned 49% of each of MexMar and OVH through SEACOR Marine International LLC, a wholly-owned subsidiary of the Company (“SEACOR Marine International”), and the remaining 51% ownership interests were held by OTM. The Company also owned a minority interest in SEACOR Marlin LLC, the owner of the PSV SEACOR Marlin, and the remaining ownership interests of SEACOR Marlin were held by MexMar. The Framework Agreement provided for, among other things, (i) the sale by the Company of all of the outstanding equity interests of SEACOR Marine International to OTM for a purchase price of $66 million, (ii) the sale by the Company of the SEACOR DAVIS anchor handling towing supply vessel to CME Ireland in exchange for the remaining equity interests in SEACOR Marlin LLC, such that SEACOR Marlin LLC would become a wholly-owned subsidiary of the Company, (iii) the transfer of a hybrid battery system from OVH to the Company as repayment in full of a certain vessel loan agreement by the Company to its former joint venture, and (iv) entry into a bareboat charter agreement between SEACOR Marlin LLC and MexMar (collectively, the “Framework Agreement Transactions”).

In connection with the closing of the Framework Agreement Transactions, on September 29, 2022, SEACOR Marine Capital Inc., a wholly-owned subsidiary of the Company (“SEACOR Marine Capital”) purchased all of the outstanding loans under the Second Amended and Restated Term Loan Credit Facility Agreement, made as of July 8, 2022, by and among MexMar, as the borrower, DNB Capital LLC and The Governor and Company of the Bank of Ireland, each as lenders, and DNB Bank ASA, New York Branch, as facility agent (as amended from time to time, the “MexMar Original Facility Agreement”) for an aggregate amount of $28.8 million, representing par value of the loan. The purchase was funded using proceeds received from the Framework Agreement Transactions. On the same date the facility was amended pursuant to a Third Amended and Restated Facility Agreement (“MexMar Third A&R Facility Agreement”) to, among other things, (i) provide for the prepayment by MexMar of approximately $8.8 million of the outstanding loan amount, to reduce the outstanding principal on the loan to $20.0 million, (ii) modify the definition of “Change of Control,” (iii) modify the maturity date from January 23, 2025 to September 30, 2023, (iv) decrease the minimum cash requirement from $10.0 million to $2.5 million, (v) modify the interest margin from 4.7% to 5.0%, and (vi) modify the principal repayment profile to reflect four quarterly installments of $5.0 million to repay the loan by the maturity date. All collateral and security arrangements remain in place from the MexMar Original Facility Agreement, including a first priority mortgage on 13 offshore support vessels owned by MexMar. As a result, SEACOR Marine Capital was the sole lender to MexMar under the MexMar Third A&R Facility Agreement. This loan was repaid in full as of September 30, 2023.

Each of the Framework Agreement Transactions and the transactions entered into in connection with the MexMar Third A&R Facility Agreement (the “MexMar Facility Agreement Transactions”) were subject to the oversight of, and received advance approval from, the Audit Committee as related party transactions subject to the Company’s Related Party Transaction Policy. Mr. Miguel recused himself from the Audit Committee and the Board deliberations with respect to the Framework Agreement Transactions and the Mexmar Facility Agreement Transactions. The Board received a third-party fairness opinion with respect to the Framework Agreement Transactions.

PROPOSAL NO. 2 ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION (“SAY ON PAY”)

Pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and Section 14A of the Exchange Act, we are providing our stockholders the opportunity to vote to approve, on an advisory, non-binding basis, the compensation of our Named Executive Officers, as disclosed in this Proxy Statement in accordance with the SEC’s rules. This proposal, which is commonly referred to as “Say on Pay,” gives stockholders the opportunity, on an advisory basis, to approve or vote against Named Executive Officer compensation, or abstain from voting with respect to such proposal.

Our executive compensation program is designed to enhance stockholder value by focusing on performance factors that align with our strategic objects; attract, motivate and retain highly-qualified executives committed to the Company’s long-term success; and provide competitive salaries relative to their peers. To that end, we provide a program of cash and equity-based awards to promote executive continuity, to align the interests of the Company’s executives with those of our stockholders and to reward executives for superior performance.

We urge stockholders to read the “Compensation Discussion and Analysis” section of this Proxy Statement, which describes the Company’s executive compensation programs and the decisions made by the Compensation Committee and the Board with respect to the year ending December 31, 2023.

The Board is asking stockholders to approve the following advisory resolution at the Annual Meeting:

“RESOLVED, that the compensation paid to the Company’s Named Executive Officers, as disclosed pursuant to Item 402 of Regulation S-K in the Company’s Proxy Statement, including the Executive Compensation, compensation tables and narrative discussion contained therein, is hereby approved.”

Because the vote on this proposal is advisory in nature, it will not affect any compensation already paid or awarded to any Named Executive Officer and will not be binding on or overrule any decisions of the Company, the Board or the Compensation Committee; it will not create or imply any change to the fiduciary duties of, or create or imply any additional duties for, the Company, the Board or the Compensation Committee; and it will not restrict or limit the ability of stockholders to make proposals for inclusion in proxy materials related to executive compensation. Although non-binding, the Board and the Compensation Committee will review and consider the voting results in their entirety when making future decisions regarding our executive compensation program.

THE BOARD UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE APPROVAL OF THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT.

PROPOSAL NO. 3 RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board recommends that stockholders ratify the appointment of Grant Thornton LLP (“Grant Thornton”), independent registered public accounting firm to audit the accounts of the Company and its subsidiaries for the fiscal year ending December 31, 2024. The appointment of Grant Thornton was recommended to the Board by its Audit Committee.

Grant Thornton has been the Company’s independent registered public accounting firm since June 12, 2017, and the Audit Committee believes that the continued retention of Grant Thornton as the Company’s independent registered public accounting firm is in the best interest of the Company and its stockholders.

Representatives of Grant Thornton will be virtually present at the Annual Meeting. They will have an opportunity to make a statement if they desire to do so and will be available to respond to stockholder questions after the conclusion of the Annual Meeting.

The affirmative vote of the holders of a majority in voting power of the Common Stock represented virtually or by proxy and entitled to vote at the Annual Meeting is required to ratify the appointment of Grant Thornton.

OTHER MATTERS

Other Actions at the Annual Meeting

The Board does not intend to present any other matter at the Annual Meeting. The Board has not been informed that any other person intends to present any other matter for action at the Annual Meeting. If any other matters properly come before the Annual Meeting, the persons named in the accompanying proxy intend to vote the proxies in accordance with their best judgment.

STOCKHOLDER NOMINATION OF DIRECTORS

The By-Laws establish an advance notice procedure with regard to the nomination (other than by or at the direction of the Board or a committee thereof) of candidates for election as directors (the “Nomination Procedure”). Only persons who are nominated by the Board, a committee appointed by the Board, or by a stockholder who has complied with the nomination procedures set forth in the By-Laws and provided timely written notice to the Secretary of the Company prior to the meeting at which directors are to be elected, are eligible for election as directors of the Company. To be timely, a stockholder’s notice must be delivered or mailed to and received by the Secretary of the Company at the Company’s principal executive offices not earlier than the close of business on the one hundred fiftieth (150th) day nor later than the close of business on the one hundred twentieth (120th) day prior to the first anniversary date of the previous year’s annual meeting of stockholders (or if there was no such prior annual meeting, not earlier than the close of business on the one hundred fiftieth (150th) day nor later than the one hundred twentieth (120th) day prior to the date which represents the second Tuesday in May of the current year); provided, however, that in the event that the date of the annual meeting is more than twenty-five (25) days before or after such anniversary date, then, to be considered timely, notice by the stockholders must be received not later than the close of business on the tenth (10th) day following the date on which public announcement of the date of such meeting is first made by the Company. The notice must contain (A) as to each person whom the stockholder proposes to nominate for election as a director (i) all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to and in accordance with Regulation 14A under the Exchange Act, and (ii) such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected; (B) as to any other business that the stockholder proposes to bring before the annual meeting, (i) a brief description of the business desired to be transacted, (ii) the text of the proposal or business (including the text of any resolutions proposed for consideration and, in the event that such business includes a proposal to amend the By-Laws, the language of the proposed amendment), (iii) the reasons for conducting such business at the meeting, and (iv) any material interest of such stockholder in such business; and (C) as to the stockholder giving the notice on whose behalf the nomination or proposal is made (i) the name and address, as they appear on the Company’s most recent stockholder lists, of the stockholder proposing such proposal, (ii) the class and number of shares of capital stock of the Company which are beneficially owned by the stockholder, (iii) a description of any agreement, arrangement or understanding with respect to the nomination or other proposal between or among such stockholder, any affiliate or associate, and any others acting in concert with any of the foregoing, (iv) a description of any agreement, arrangement or understanding (including any derivative or short positions, profit interests, options, warrants, stock appreciation or similar rights, hedging transactions, and borrowed or loaned shares) that has been entered into as of the date of the stockholder’s notice by, or on behalf of, such stockholder, the effect or intent of which is to mitigate loss to, manage risk or benefit of share price changes for, or increase or decrease the voting power of, such stockholder, with respect to shares of stock of the Company, (v) a representation that the stockholder is a holder of record of stock of the Company entitled to vote at such meeting and intends to appear virtually or by proxy at the meeting to propose such business or nomination, and (vi) a representation whether the stockholder intends or is part of a group which intends (a) to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the Company’s outstanding capital stock required to approve or adopt the proposal or elect the nominee or (b) otherwise to solicit proxies from stockholders in support of such proposal or nomination. Any stockholder who desires to propose any matter at an annual meeting of stockholders shall, in addition to the aforementioned requirements described in clauses (A) through (C), comply in all material respects with the content and procedural

53

requirements of Rule 14a-8 of Regulation 14A under the Exchange Act, irrespective of whether the Company is then subject to such rule or said act. The presiding officer of the meeting may refuse to acknowledge nomination of any person not made in compliance with the Nomination Procedure.

Although the By-Laws do not empower the Board with the right to approve or disapprove of stockholder nominations for the election of directors or any other business properly brought by the Company’s stockholders at any annual or special meeting, the foregoing Nomination Procedure may nevertheless have the effect of (i) precluding a nomination for the election of directors or precluding the transaction of business at a particular meeting if the proper procedures are not followed, or (ii) deterring a third party from conducting a solicitation of proxies or contest to elect his or its own slate of director nominees or otherwise attempting to obtain control of the Company.

54

STOCKHOLDER PROPOSALS FOR THE 2025 ANNUAL MEETING

Proposals that stockholders believe should be voted upon at the Company’s annual meeting of stockholders may be eligible for inclusion in the Company’s Proxy Statement. In accordance with the provisions of Rule 14a-8 under the Exchange Act, Stockholder proposals for the 2025 annual meeting of stockholders must be received by the Company on or before December 31, 2024, to be eligible for inclusion in the proxy statement and proxy card relating to the 2024 annual meeting of stockholders, unless the Company determines to hold the meeting more than 30 days before or after the anniversary of the 2023 meeting. Under those circumstances, the Company will issue a public announcement as soon as it determines the meeting date and stockholder proposals will need to be submitted within a reasonable time before the Company expects to print the proxy. Any such proposals should be sent via registered, certified or express mail to: Corporate Secretary, SEACOR Marine Holdings Inc., 12121 Wickchester Lane, Suite 500, Houston, Texas 77079.

As a separate and distinct matter from proposals under Rule 14a-8, in accordance with Article I, Section 3 of the By-Laws of the Company, in order for business to be properly brought before the next annual meeting by a stockholder, such stockholder must deliver to the Company timely notice thereof. To be timely, a stockholder’s notice must be delivered or mailed to and received by the Corporate Secretary at the principal executive offices of the Company, not earlier than the close of business on the one hundred fiftieth (150th) day nor later than the close of business on the one hundred twentieth (120th) day prior to the first anniversary date of the previous year’s annual meeting (or if there was no such prior annual meeting, not earlier than the close of business on the one hundred fiftieth (150th) day nor later than the one hundred twentieth (120th) day prior to the date which represents the second Tuesday in May of the current year); provided, however, that in the event that the date of the annual meeting is more than twenty-five (25) days before or after such anniversary date, then, to be considered timely, notice by the stockholders must be received not later than the close of business on the tenth (10th) day following the date on which public announcement of the date of such meeting is first made by the Company. In no event shall the public announcement of an adjournment or postponement of an annual meeting commence a new time period (or extend any time period) for the giving of a stockholder’s notice as described above.

For the Board of Directors,

Andrew H. Everett II

Senior Vice President,

General Counsel and Secretary

IMPORTANT INFORMATION

Voting Information

Your broker is not permitted to vote on your behalf on the election of directors and other matters to be considered at the Annual Meeting (except on ratification of the selection of Grant Thornton as auditors for 2024), unless you provide specific instructions by completing and returning the voting instruction card. For your vote to be counted, you now must communicate your voting decisions to your broker, bank or other financial institution before the date of the Annual Meeting.

Your Participation in Voting the Shares You Own is Important

Voting your shares is important to ensure that you have a say in the governance of your company and to fulfill the objectives of the majority voting standard that we apply in the election of directors. Please review the proxy materials and follow the instructions on the proxy card or voting instruction card to vote your shares. We hope you will exercise your rights and fully participate as a stockholder in our Company’s future.

Annual Report

A copy of the Company’s 2023 Annual Report accompanies this Proxy Statement and should be read in conjunction herewith.

Householding

The SEC permits a single set of annual reports and proxy statements to be sent to any household at which two or more stockholders reside if they appear to be members of the same family. Each stockholder continues to receive a separate proxy card. This procedure, referred to as “householding,” reduces the volume of duplicate information stockholders receive and reduces mailing and printing expenses. A number of brokerage firms have instituted householding.

As a result, if a stockholder holds shares through a broker and resides at an address at which two or more stockholders reside, that stockholder will likely be receiving only one annual report and proxy statement unless any stockholder at that address has given the broker contrary instructions. However, if any such stockholder residing at such an address wishes to receive a separate annual report or proxy statement in the future, or if any such stockholder that elected to continue to receive separate annual reports or proxy statements wishes to receive a single annual report or proxy statement in the future, that stockholder should contact their broker or send a request to the Secretary at the Company’s principal executive offices. The Company will deliver, promptly upon written or oral request to the Secretary, a separate copy of the 2023 Annual Report and this Proxy Statement to a stockholder at a shared address to which a single copy of the documents was delivered.

More Information is Available

If you have any questions about the proxy voting process, please contact the broker, bank or other financial institution where you hold your shares. The SEC also has a website (www.sec.gov/spotlight/proxymatters.shtml) with more information about your rights as a stockholder. Additionally, you may contact the Company’s Investor Relations Department by mail sent to 12121 Wickchester Lane, Suite 500, Houston, Texas 77079, Attention: Investor Relations, or by email at InvestorRelations@seacormarine.com.

The dollar amounts do not reflect the actual amount of compensation earned by or paid to Mr. Gellert during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to Mr. Gellert’s total compensation for each year to determine the “compensation actually paid”:

Year	Reported Summary Compensation Table Total for PEO ($)		Reported Value of Equity Awards(a) ($)			Equity Award Adjustments(b) ($)		Compensation Actually Paid to PEO ($)

The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant. The amounts deducted or added in calculating the equity award adjustments are as follows:

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

In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to average total compensation for the NEOs as a group (excluding Mr. Gellert) for each year to determine the “compensation actually paid,” using the same methodology described above in Note (2)(b):

2021		411,815		19,061		—		85,356		—			—		516,232

(5) Cumulative total shareholder return is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period. The “measurement period” is the period beginning at the measurement point established by the market close on the last trading day before fiscal year 2021, through and including the end of the fiscal year for which cumulative total shareholder return is being calculated.

In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to average total compensation for the NEOs as a group (excluding Mr. Gellert) for each year to determine the “compensation actually paid,” using the same methodology described above in Note (2)(b):

Year	Average Reported Summary Compensation Table Total for Non-PEO NEOs ($)		Average Reported Value of Equity Awards ($)			Average Equity Award Adjustments(a) ($)		Average Compensation Actually Paid to Non-PEO NEOs ($)
2023		1,903,231		(1,015,031	)		1,858,433		2,746,633
2022		1,518,054		(749,046	)		2,010,839		2,779,848
2021		1,370,007		(725,207	)		516,232		1,161,032

(a) The amounts deducted or added in calculating the total average equity award adjustments are as follows:

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