Dear Stockholder:

You are cordially invited to attend the 2022 Annual Meeting of Stockholders (the “Annual Meeting”) of SEACOR Marine Holdings Inc. (the “Company”) on Tuesday, June 7, 2022, 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 18, 2022, will be entitled to vote at the Annual Meeting. Your virtual attendance at the 2022 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, 2021 (the “2021 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

Notice of 2022 Annual Meeting

And

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 18, 2022 (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 26,648,874 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:

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 below under “Proxy Cards.”

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, present in person or by proxy.

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 below) are not counted for purposes of the election of directors and will not affect the outcome of such election. Our stockholders do not have cumulative voting rights for the election of directors.

For matters other than the election of directors, stockholders may vote in favor of or against the proposal or may abstain from voting.

For matters other than the election of directors, the affirmative vote of a majority of the shares of Common Stock present virtually or by proxy and voting on the matter is required for approval of those matters. 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 “Shares Held in Street Name.”

1

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

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. 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, the proposal to approve the SEACOR Marine Holdings Inc. 2022 Equity Incentive Plan 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 have the authority to vote on the ratification of the appointment of Grant Thornton LLP, as the Company’s independent registered public accounting firm. 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 count toward the size of the quorum but are not voted in favor of the proposal, they will have the effect of a vote “against” Proposal 2.

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 – Election of Directors” in this Proxy Statement and listed under Item 1 of the enclosed proxy card; FOR “Proposal No. 2 – Approval of the SEACOR Marine Holdings Inc. 2022 Equity Incentive Plan” in this Proxy Statement and listed under Item 2 of the enclosed proxy card; and FOR “Proposal No. 3 – Ratification of 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.

2

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 “Attending the Annual Meeting Virtually” above. 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.

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 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 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 below under “Communications with the Board or Independent Directors.”

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. Currently, the Board is composed of five directors.

During 2021, the Board held eight meetings. The Board also acted pursuant to unanimous written consent on five 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 2021. We encourage members of our Board to attend our Annual Meeting of Stockholders. All members of our Board attended the 2021 Annual Meeting and plan to virtually attend the 2022 Annual Meeting.

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

4

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 Messrs. Andrew R. Morse and 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.

Pursuant to the note purchase agreement (the “Note Purchase Agreement”) and the investment agreement (the “Investment Agreement”), which the Company entered into with investment funds managed and controlled by the Carlyle Group (“Carlyle”) in connection with the issuance of the Convertible Notes (as defined below), the Company must 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. During 2017 and the beginning of 2018, Ferris Hussein served on the Board as the director designated by Carlyle until April 17, 2018, when he resigned. Since Mr. Hussein’s resignation from the Board, Carlyle has determined not to exercise its right to designate a director. 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 Note Purchase Agreement. This observation right will terminate at the time Carlyle owns less than $50.0 million in aggregate principal amount of the convertible notes issued under the Note Purchase Agreement (the “Convertible Notes”) or a combination of the Convertible Notes and our Common Stock representing less than 5.0% of our Common Stock outstanding on a fully diluted basis, assuming the conversion of all Convertible Notes and warrants to purchase our Common Stock held by Carlyle. Carlyle has exercised this observer right with respect to most board meetings during 2021 and we expect they will continue to do so as long as they maintain that right under the Investment 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 conflict of interest with management. Executive sessions are generally presided over by the Company’s Non-Executive Chairman, Mr. Morse, who is responsible for:

5

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: Messrs. Morse and Regan, and Ms. Persily, all of whom 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 Securities and Exchange Commission (“SEC”). In reaching this determination, the Board considered, among other things, Mr. Morse’s over 25 years of experience as an investment banker, in addition to his other experience that is described below. 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. The Audit Committee is expected to meet at least quarterly. The Audit Committee met four times during 2021 and acted pursuant to unanimous written consent on three other occasions.

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

6

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: Messrs. Regan and Morse, and Ms. Persily, all of whom 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 six times during 2021 and it also took action pursuant to unanimous written consent on two other occasions.

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

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 2021, 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: Messrs. Regan and Morse, and Ms. Persily, all of whom served since the last annual meeting of stockholders and

7

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 five times during 2021 and it also acted pursuant to unanimous written consent on one other occasion.

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

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 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:

8

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 below 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 below 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 “Stockholder Proposals for the 2023 Annual Meeting” below. 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. 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. The independent directors have 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 is 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. In accordance with Section 806 of the Sarbanes-Oxley Act of 2002, as amended (the “Sarbanes-Oxley Act”), these

9

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, cyber-security 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:

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 e-mail, telephone conference and in-person meetings, and during formal Board meetings. Senior management makes formal presentations to the Board regarding risk management issues at least once per year. Our Non-Executive Chairman, as well as 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 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 Nominating and Corporate Governance Committee oversees the Company’s ESG program and sustainability initiatives, including the Company’s Sustainability Council. See “ESG and Sustainability Council” below for additional information regarding the Company’s sustainability initiatives, including the publication of the Sustainability Council’s Inaugural Sustainability Report.

10

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, enable 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.

Code of Business Conduct and Ethics

The Board has adopted a set of Corporate Governance Guidelines, a Code of Business Conduct & 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.

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 & 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 is overseen by its Sustainability Council, which was formed on September 17, 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, including, but not limited to environmental protection, clean energy technology, social responsibility, employee, contractor and community engagement, health and safety, and community empowerment. Together with the Board of Directors, the Sustainability Council helps establish 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.

On December 13, 2021, the Sustainability Council published its Inaugural Sustainability Report documenting the Company’s recent achievements in three areas: commitment to employees, environmental impact, and responsibility 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 a coming 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%. We own and operate the only hybrid well stimulation vessel in operation in the world, which reflects our continued commitment to investment in green technology solutions. As an industry leader, we are committed to complying with the International Maritime Organization (“IMO”) 2020 Sulphur cap and lowering emissions overall, and we are encouraged by the IMO 2030 targets. In 2020, we

11

incorporated changes across our organization to abide by the IMO 2020 Sulphur cap. We are working towards IMO’s target of cutting carbon dioxide (CO₂) emissions by at least 50% by 2050, compared to 2008 levels, with carbon intensity reduced 40% by 2030. We are also ensuring 100% compliance with emissions-related regulatory demands, and we are reducing the emissions intensity of air pollutants like nitrogen oxides and sulphur oxides generated by our fleet to work towards IMO goals of at least a 50% reduction by 2050.

We are also committed to improving ocean health and reducing waste. We are committed to the protection of the marine environment, including High Conservation Value (“HCV”) areas. HCV areas are identified on nautical charts with notes to seafarers on precautions to be taken in these areas, such as no anchoring, or when possible, avoiding the area altogether. Our vessels are fully compliant with the current IMO Ballast Water Management Convention (“IMO BWM Convention”) and, by 2024, as required by the IMO BWM Convention, all vessels will be fitted with Ballast Water Treatment Systems. In a number of our vessels in European Union waters, we are also beginning to add Inventories of Hazardous Materials (“IHM”). In 2020, we launched extensive research into initiatives which can reduce waste both in our shoreside operations and on board our vessels, including initiatives on reducing water consumption, plastic waste, lubricant waste, cleaning product waste, printing paper and ink reduction, food waste and vessel recycling. The initiatives span our entire business.

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.

During 2021, non-employee directors were paid an annual retainer of $50,000 and such directors are also eligible to participate in the SEACOR Marine Holdings Inc. 2020 Equity Incentive Plan (the “2020 Plan”) that is administered by the Compensation Committee. 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 during 2020 and 2021, in a way that was equitable to both directors and shareholders alike, for purposes of calculating the number of restricted and unrestricted shares of Common Stock granted to the non-employee directors in 2021, the Compensation Committee determined it was appropriate to use the same stock price that the Compensation Committee used to calculate the number of restricted shares granted to NEOs in March of 2021. Because the Company’s stock price had increased from March 2021 to June 2021, the number of restricted and unrestricted shares of Common Stock granted to the non-employee directors in respect of their 2021 annual equity retainer ended up being higher than it would have been had the closing price on the grant date been used. The same methodology was used in 2020, and it is important to note that, with respect to the 2020 annual equity retainer for non-employee directors, using the same stock price that was used to calculate the number of restricted shares granted to NEOs in March of 2020 resulted in non-employee directors receiving less shares that they would have received had the closing price on the grant date been used, because the Company’s stock price had decreased between March 2020 to June 2020.

On June 8, 2021, 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 $154,190, comprised of 14,444 unrestricted shares of Common Stock and 21,666 restricted shares of Common Stock. As Non-Executive Chairman, Mr. Morse was granted an annual equity award with a grant date fair value of $54,396, comprised of 12,739 unrestricted 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 $13,600, comprised of 3,185 unrestricted shares of Common Stock (with the exception of Mr. Morse, who was granted an annual equity award with a grant date fair value of $27,200, comprised of 6,370 unrestricted 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 $13,600, comprised of 3,185 unrestricted shares of Common Stock (with the exception of Mr. Regan, who was granted an annual equity award with a grant date fair value of $27,200, comprised of 6,370 unrestricted 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 $6,802, comprised of unrestricted 1,593 shares of Common Stock (with the exception of Mr. Regan, who was granted an annual equity award with a grant date fair value of $13,600, comprised of 3,185 unrestricted shares of Common Stock as the chairperson of the Nominating and Corporate Governance Committee). The unrestricted shares of Common Stock were fully vested as of the date of grant, and the restricted shares of Common Stock vest after one year.

EXECUTIVE COMPENSATION

Currently, the Company is an “emerging growth company” and, under the Jumpstart Our Business Startups Act, is exempt from certain executive compensation disclosures otherwise required by Item 402 of Regulation S-K (including the disclosure required to be provided pursuant to a “Compensation, Discussion & Analysis”), as well as from holding say-on-frequency and say-on-pay advisory votes on executive compensation. However, we are providing certain information related to the Company’s 2021 compensation decisions that should be read in conjunction with the compensation tables provided later in this Proxy Statement. This discussion and the compensation tables that follow set forth the compensation of the following “Named Executive Officers” or “NEOs” of the Company:

Compensation Actions in Connection with the Spin-off

In connection with the Spin-off, the compensation committee of SEACOR Holdings took certain actions during 2017 to appropriately address the impact of the Spin-off on SEACOR Holdings’ outstanding equity awards. In general, outstanding stock options to acquire shares of SEACOR Holdings’ Common Stock were adjusted to preserve the aggregate intrinsic value of such stock options pre- and post-Spin-off. In addition, the compensation committee of SEACOR Holdings approved the vesting of SEACOR stock options and SEACOR restricted stock awards held by employees of the Company and individuals who joined the Company following the Spin-off. Other than Messrs. Everett and Rossmiller, who were not employees at the time, each of the Named Executive Officers received 1.007 restricted shares of the Company’s Common Stock for every restricted share of SEACOR Holdings’ Common Stock held as of the record date for the Spin-off.

Summary of 2021 Compensation Elements

Following the Spin-off, the Company’s Compensation Committee took certain actions and made certain compensation-related decisions that were based on the compensation philosophies and arrangements in place at SEACOR Holdings that the Compensation Committee felt were also appropriate for the Company’s executive officers. For example, the Board adopted the 2017 Plan for the purpose of granting equity-based compensation awards, and in April 2020, the Board adopted the 2020 Plan subject to the approval of the Company’s stockholders. The 2020 Plan was approved by the Company’s stockholders at the 2020 annual meeting. The 2017 Plan and 2020 Plan are collectively referred to herein as the “SEACOR Marine Equity Incentive Plans.” The Compensation Committee also implemented the following executive compensation practices:

22

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.

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. The companies with similar lines of operating business considered in connection with the Compensation Committee’s compensation analysis include Archrock, Inc., Bristow Group Inc., Dril-Quip, Inc., Exterran Corporation, Forum Energy Technologies, Inc., Gulf Island Fabrication, Inc., Helix Energy Solutions Group, Inc., Newpark Resources, Inc., Oil States International, Inc. RPC, Inc., TETRA Technologies, 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.

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 2021, the Compensation Committee elected to continue to retain Lyons Benenson as its independent compensation consultant to assist it in reviewing and making recommendations with respect to executive compensation and to review the total target compensation opportunities of the executive officers. Lyons Benenson has acted as an independent compensation consultant to the Company 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 compensation.

23

Prior to the retention of Lyons Benenson, the Compensation Committee evaluated Lyons Benenson’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 Lyons Benenson is independent and that its work for the Compensation Committee does not raise any conflicts of interest.

Elements of 2021 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. During 2021 the Compensation Committee, in consultation with Lyons Benenson, 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.

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 ongoing impact of the COVID-19 pandemic on the Company’s operations and 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 2021. Following the end of 2021, the Compensation Committee determined that it was appropriate to award cash bonuses to the Named Executive Officers in respect of 2021 performance, after taking into consideration the following factors: (i) the individual contributions of the Named Executive Officers during 2021, 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 2022 the Compensation Committee approved the payment of cash bonuses as follows: $450,000, $400,000, $350,000 and $300,000 for each of Mr. Gellert, Mr. Llorca, Mr. Everett and Mr. Rossmiller, respectively. 60% of such cash bonuses were paid in April 2022, and 20% of such cash bonuses will be paid in the first quarter of 2023 and 2024, 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 the applicable NEO’s employment agreement), then any unpaid portion of the 2021 annual cash bonus will be paid out in connection with such event.

Long-term Incentives

As discussed above, during 2017, the Company adopted the 2017 Plan, and during 2020, the Company adopted the 2020 Plan. 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.

24

In March 2021, 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 2021.

The restricted stock awards vest ratably over three years beginning on March 4, 2022, subject to continued employment on each applicable vesting date, subject to 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 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 $3.98, $4.53, $5.11, $5.69 and $6.24, respectively. The Compensation Committee did not approve any other equity awards to the Named Executive Officers during 2021.

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 vested 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 2021 is set forth in the table below:

In determining the applicable target grant date fair 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 2021 awards, the Compensation Committee determined that it would be appropriate to use a 60-day volume weighted average closing price (“VWAP”) of the Company’s stock price for purposes of calculating restricted stock and PRSU awards, and determined not to grant any stock option awards in 2021. On the day the March 2021 awards were granted, the closing price of our common stock was $5.72, and the 60-day VWAP was $3.14. 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 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 reflects 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.

25

On February 9, 2022, the PRSUs granted in 2019 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 expiration of the three-year performance period.

Stock Ownership

Currently, the Company has no formal policy requiring employees to retain vested restricted stock or options, but it prefers that executive officers maintain ownership and considers executive ownership levels when determining compensation packages.

Clawback Policy

The award agreements applicable to any stock options, restricted stock and PRSU awards granted to the Named Executive Officers in 2017, 2018, 2019, 2020 and 2021 provide that the shares of Common Stock underlying such awards are subject to any applicable clawback policy of the Company or other clawback provision(s) as may be required pursuant to any applicable law, government regulation or stock exchange listing.

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 shareholders. 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”). During 2021, the Company matched employee contributions to the SEACOR Marine 401(k) Plan in the amount of 100% of the first 1.0% of an employee’s salary that the employee contributed to the SEACOR Marine 401(k) Plan, and 50% of the next 2% of the employee’s salary that the employee contributed to the SEACOR Marine 401(k) Plan, for a total match of 2% of such employee’s salary.

In connection with a review of the Company’s executive compensation arrangements, 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 2021 the Compensation Committee, in consultation with Lyons Benenson, 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.

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.

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 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 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:

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Transactions Regarding SEACOR Holdings

In connection with the Spin-off, the Company entered into certain agreements with SEACOR Holdings that govern the Company’s relationship with SEACOR Holdings following the Spin-off, including a Distribution Agreement, two Transition Services Agreements and a Tax Matters Agreement, among others. The summaries of certain of these agreements set forth below are qualified in their entireties by reference to the full text of the applicable agreements.

Pursuant to the Transition Services Agreement with SEACOR Holdings, SEACOR Holdings charged the Company a fee of 0.5% on outstanding guaranteed amounts, which declined as the guaranteed obligations were settled by the Company. The Company recognized a de minimis amount of guarantee fees in connection with sale-leaseback arrangements in 2021. As of December 31, 2021, SEACOR Holdings had no outstanding guarantees for obligations of the Company.

Tax Refund and Indemnification Agreement

On June 26, 2020, the Company entered into a Tax Refund and Indemnification Agreement (the “Tax Refund Agreement”) with SEACOR Holdings. The Tax Refund Agreement enabled the Company to utilize net operating losses (“NOLs”) generated in 2018 and 2019 to claim refunds for tax years prior to the Company’s spin-off from SEACOR Holdings in 2017 (at which time the Company was included in SEACOR Holdings consolidated tax returns) that were permitted to be carried back pursuant to the provisions of the CARES Act and for which SEACOR Holdings needed to claim the refund on behalf of the Company.

As a result, the Company received an aggregate amount of cash tax refunds of $32.3 million (including $1.1 million of interest paid by the IRS in respect of refund payment delays due in part to the COVID-19 pandemic), of which $12.5 million was received prior to March 31, 2021, and the remaining $19.8 million was received in April 2021. Additionally, a $3.0 million transaction fee was paid to SEACOR Holdings concurrently with the signing of the Tax Refund Agreement as consideration for its cooperation in connection with the filing of the applicable tax refund returns. The Tax Refund Agreement did not restrict the use of approximately $23.1 million of the refund and required the remaining approximately $8.1 million to be deposited into an account to be used solely to satisfy certain of the Company’s obligations that remained guaranteed by SEACOR Holdings which primarily related to vessel operating leases. Two of these vessel operating leases expired in the fourth quarter of 2020, which reduced the remaining guarantee on the three remaining vessels to $7.0 million. The remaining three vessel operating leases that SEACOR Holdings guaranteed expired in 2021 and the Company applied the amount deposited to satisfy these obligations.

Transactions Regarding OSV Partners

OSV Partners

In 2013, SEACOR OSV Partners I LP (the “OSV Partners I”) was formed to own and operate offshore support vessels with the Company (then a subsidiary of SEACOR Holdings) holding 30.4% of the initial limited partner interests (“Initial LP Interests”) and a majority of the general partner interests, and the remaining Initial LP Interests held by unrelated third parties. The Company was also appointed the manager of the vessels owned by OSV Partners I entitled to a market management fee.

In December 2014, Charles Fabrikant (a former Non-Executive Chairman of the Company), John Gellert (President, Chief Executive Officer and Director of the Company), Jesús Llorca (Executive Vice President and Chief Financial Officer of the Company) and other individuals (some of whom were affiliated with the Company’s former parent, SEACOR Holdings), invested in Caroline International Holdings LLC (“Caroline”) and Caroline International Holdings II LLC (“Caroline II” and together with Caroline, the “Caroline Entities”), two entities managed by Mr. Fabrikant and formed solely for the purposes of investing in OSV Partners I. As of December 31, 2021, the aggregate investments of Messrs. Fabrikant, Gellert and Llorca in the Caroline Entities were $0.3 million, $0.4 million and $0.2 million, respectively. No other current executive officer or member of the Board invested in or has any interests in the Caroline Entities.

36

The following summarizes the investments made by the Caroline Entities in OSV Partners I:

Immediately prior to the closing of the Merger described in “OSV Partners Merger” below, the Company owned 30.4% of the Initial LP Interests, 38.6% of the 2017 Preferred Interests, 43.0% of the Class A Preferred Interests, and 43.0% of the PIK Loan Debt of OSV Partners I. Beginning in January 2019, the Company agreed not to charge OSV Partners I the management fee it was contractually entitled to through December 31, 2021, due to continuing liquidity issues of OSV Partners I. For the years ended December 31, 2018, and 2017, the Company received $0.6 million of vessel management fees from OSV Partners I for each year.

On October 29, 2021, in exchange for $2.2 million, the Company acquired from a third-party lender approximately $4.1 million of the $22.1 million of principal owed under OSV Partner I’s amended and restated senior secured term loan credit facility agreement dated as of September 28, 2018 (the “OSV Credit Facility” and such acquisition, the “First Lien Debt Acquisition”).

OSV Partners Merger

On December 31, 2021, pursuant to a merger agreement, OSV Partners I merged with and into SEACOR Offshore OSV LLC, an indirect wholly owned subsidiary of the Company (“SEACOR Offshore OSV”), with SEACOR Offshore OSV surviving the merger (“Merger”). In connection with the consummation of the Merger, the Company issued an aggregate of 1,567,935 shares of Common Stock to the limited partners of OSV Partners I as follows:

In connection with the consummation of the Merger, (i) Caroline received an aggregate number of 73,107 shares of Common Stock and (ii) Caroline II received an aggregate of 36,570 shares of Common Stock. Each of the Caroline Entities distributed to its members the Common Stock received in connection with the consummation of the Merger with Mr. Fabrikant receiving 20,172 shares, or 1.3% of the aggregate number of shares issued as Merger Consideration and PIK Loan Consideration, Mr. Gellert receiving 22,353 shares, or 1.4% of the aggregate number of shares issued as Merger Consideration and PIK Loan Consideration, and Mr. Llorca receiving aggregate distributions of 9,174, or 0.6% of the aggregate number of shares issued as Merger Consideration and PIK Loan Consideration. In addition, a trust of which Mr. Gellert is one of several beneficiaries received an aggregate number of 26,557 shares of Common Stock.

37

In connection with the Merger, the Company and SEACOR Offshore OSV assumed and guaranteed approximately $18.1 million of indebtedness outstanding under the OSV Credit Facility. The OSV Credit Facility requires quarterly principal payments of $0.5 million. Interest accrues under the OSV Credit Facility at a rate of Term SOFR (as defined in the OSV Credit Facility) plus 4.68% plus Mandatory Costs (as defined in the OSV Credit Facility), if applicable. The OSV Credit Facility matures on December 31, 2023 and may be accelerated upon the occurrence of an event of default.

The First Lien Debt Acquisition and the Merger 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. Gellert recused himself from the Audit Committee deliberations with respect to the First Lien Debt Acquisition and from both the Audit Committee and Board deliberations with respect to the Merger. In addition, the Board received a third-party fairness opinion with respect to the Merger. Mr. Llorca was also not involved in the related discussions. Mr. Fabrikant no longer served on the Board as of June 8, 2021, and therefore had no participation in any of the approval processes for these transactions.

As a result of the Merger, the five 201’, 1,900 tons deadweight capacity, platform support vessels owned by OSV Partners I are now 100% owned by the Company, bringing the Company’s owned PSV fleet to 20. Of the five PSVs previously owned by OSV Partners, three are U.S. flagged and currently located in the Gulf of Mexico, and two are Marshall Island flagged and currently located in the Middle East. As of December  31, 2021, these five PSVs have an average age of seven years.

Transactions Regarding Carlyle

On December 1, 2015, the Company issued $175.0 million aggregate principal amount of its Convertible Notes to investment funds managed and controlled by Carlyle. Interest on the Convertible Notes is payable semi-annually on June 15 and December 15 of each year, commencing June 15, 2016. A description of the Convertible Notes is available in the Company’s 2021 Annual Report on Form 10-K.

Pursuant to the note purchase agreement for the Convertible Notes and the Investment Agreement, the Company must use reasonable best efforts, subject to its directors’ fiduciary duties, to cause a person designated by Carlyle 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, continues to own, or would own 10.0% or more of our outstanding shares of Common Stock. During 2017, Ferris Hussein served on the Board as the director designated by Carlyle until his resignation on April 17, 2018. Carlyle has not exercised this right following Mr. Hussein’s resignation but retains the right to appoint a Board member. A representative of Carlyle observes meetings of the Board pursuant to Carlyle’s observer rights under the Convertible Notes. This observation right will terminate at the time Carlyle owns less than $50.0 million in aggregate principal amount of the Convertible Notes or a combination of the Convertible Notes and our Common Stock representing less than 5.0% of the Company’s Common Stock outstanding on a fully diluted basis, assuming the conversion of all the Convertible Notes and Warrants to purchase Common Stock held by Carlyle.

Transactions Regarding CME

Mr. Miguel, who was appointed as director at the 2019 Annual Meeting, currently serves as President and Chief Executive Officer of CME.

During 2021, the Company earned charter and related revenue of $15.4 million and management and technology fees of $0.3 million from Mantenimiento Express Maritimo, S.A.P.I. de C.V. (“MexMar”), a joint venture company that is 49% owned by a wholly owned subsidiary of the Company and 51% owned by subsidiaries of CME. These agreements and transactions with MexMar were negotiated at arms-length in the ordinary course of business. In accordance with the Related Party Transaction Policy of the Company, the Audit Committee has adopted guidelines for addressing ongoing CME-related transactions.

38

On December 20, 2018, MEXMAR Offshore International LLC (“MEXMAR Offshore”), a joint venture that is 49.0% owned by a subsidiary of the Company and 51.0% owned by a subsidiary of CME, acquired UP Offshore (Bahamas) Ltd (“UP Offshore”). UP Offshore was acquired for nominal consideration. In connection with the acquisition, UP Offshore’s existing debt was refinanced with $95.0 million of new indebtedness composed of (i) a $70.0 million six-year debt facility provided by UP Offshore’s existing lenders that is non-recourse to the Company, CME or any of their respective subsidiaries, (ii) a $15.0 million loan from MexMar, a joint venture between CME and the Company, to fund capital expenditures on two vessels and (iii) a $10.0 million loan from MEXMAR Offshore to fund working capital requirements funded by an approximate $5.0 million capital contribution to MEXMAR Offshore by each of the Company and CME. Due to losses from equity earnings, the Company’s investment in MEXMAR Offshore was written down to $0 in 2019. In July 2020, MEXMAR Offshore purchased $70.0 million of UP Offshore’s debt for $5.5 million from a consortium of banks in Brazil, of which the Company’s commitment was $2.7 million to fund this purchase. The Company advanced $1.96 million of this commitment in 2020 with the remainder funded in 2021.

On June 1, 2021, MEXMAR Offshore completed the sale of eight vessels and certain Brazilian entities to Oceanpact Servicos Maritimos S.A. and its subsidiary, OceanPact Netherlands B.V., for a total purchase price of $30.2 million (the “UP Offshore Sale Transaction”), which resulted in an equity earnings gain from 50% or less owned companies of $2.6 million. On July 23, 2021, the Company received a distribution from MEXMAR Offshore in the amount of $12.0 million of which $9.4 million was in excess of the Company’s investment balance of $2.6 million. The excess was recorded by the Company as a gain from return of investments in 50% or less owned companies.

After giving effect to the UP Offshore Sale Transaction, MEXMAR Offshore, indirectly through certain subsidiaries of UP Offshore, retained ownership of three vessels. As part of the winddown of the MEXMAR Offshore joint venture, ownership of two of these vessels was transferred from subsidiaries of UP Offshore to Offshore Vessels Holding, S.A.P.I. DE. C.V. (“OVH”), a joint venture company that is 49% owned by a wholly owned subsidiary of the Company and 51% owned by a subsidiary of CME, on October 26, 2021, and the remaining vessel was transferred from a subsidiary of UP Offshore to OVH on November 2, 2021. Upon completion of these transactions, MEXMAR Offshore no longer held income producing assets and as a result, on December 9, 2021, the Company transferred its 49% interest in MEXMAR Offshore to a subsidiary of CME for nominal consideration and a transaction fee of $0.2 million. As of December 31, 2021, the Company does not have any ownership interest in MEXMAR Offshore.

The Company also participates in a variety of other joint ventures with CME, including MexMar, OVH, and SEACOR Marlin LLC, a joint venture company that is 49% owned by a wholly owned subsidiary of the Company and 51% owned by a wholly owned subsidiary of MexMar. The joint venture agreements for each of these joint ventures were negotiated at arms-length in the ordinary course of business. During the year ended December 31, 2021, there was a distribution to the Company from SEACOR Marlin of $2.5 million. On December 10, 2021, OVH and Operadora Productora y Exploradora Mexicana S.A. de C.V., a drilling company in Mexico and affiliate of CME (“OPEM”) settled the $10.0 million loan in exchange for OPEM making an early repayment of $10.5 million, reflecting repayment of the principal amount in full and a prepayment discount and forgiveness of approximately $4.1 million of accrued interest. During 2021, the Company earned management and technology fees of $1.0 million from OVH.

Transactions Regarding Talos Energy

On February 17, 2020, Mr. Abendschein, was appointed to the position of Executive Vice President and Head of Operations at Talos Energy Inc. (together with its subsidiaries and affiliates, “Talos Energy”). Talos Energy is a customer of the Company and its subsidiaries, primarily with respect to the chartering of liftboats and other vessels. The Company’s relationship with Talos Energy was considered by the Nominating and Corporate Governance Committee and by the Board of Directors of the Company, and each determined that this relationship did not disqualify Mr. Abendschein from satisfying the independence standards under Section 303A.02 of the NYSE Listed Company Manual and the director independence standards of the Company while he served as a director of the Company. In accordance with the Related Party Transaction Policy of the Company, the Audit Committee adopted guidelines for addressing ongoing Talos Energy-related transactions. Mr. Abendschein resigned from the Board on June 8, 2021.

PROPOSAL NO. 2 APPROVAL OF THE SEACOR MARINE HOLDINGS INC. 2022 EQUITY INCENTIVE PLAN

We currently have one active equity incentive plan, the SEACOR Marine Holdings Inc. 2020 Equity Incentive Plan (the “2020 Plan”). On April 20, 2022, the Board adopted the SEACOR Marine Holdings Inc. 2022 Equity Incentive Plan (referred to herein as the “Plan”), subject to the approval of our stockholders, in order to increase the number of shares available for equity compensation awards to key employees and other eligible individuals. If the Plan is approved by our stockholders at the annual meeting (such date, the “Effective Date”), no future equity awards will be made pursuant to the 2020 Plan following the Effective Date (but existing outstanding awards under the 2020 Plan will remain subject to the terms of the 2020 Plan). The Plan, if approved, will expire in 2032. In the event that our stockholders do not approve the Plan, it will not become effective, no awards will be granted under the Plan, and the 2020 Plan will continue in accordance with its terms as previously approved by our stockholders.

Summary of the Plan

Set forth below is a summary of the principal features of the Plan. The terms of the Plan are materially consistent with the terms of the 2020 Plan, except where otherwise noted below. This summary is qualified in its entirety by reference to the terms of the Plan, a copy of which is included in this Proxy Statement as Annex A.

Why We Believe You Should Vote for this Item

We believe our future success depends in part on our ability to attract, motivate and retain high quality employees, directors and consultants and that the ability to provide equity-based and/or incentive-based awards under the Plan is critical to achieving this success. We would be at a significant competitive disadvantage if we could not use stock-based awards to recruit and compensate these individuals. Replacing equity awards with cash would also increase cash compensation expense and use cash that would be better utilized if reinvested in our businesses or returned to our stockholders.

The use of our stock as part of our compensation program is also important to our continued success because we believe it fosters a pay-for-performance culture that is an important element of our overall compensation philosophy. Equity compensation aligns the compensation interests of our directors, employees and consultants with the investment interests of our stockholders and promotes a focus on long-term value creation because our equity compensation awards can be subject to vesting and/or performance criteria.

The Plan permits the granting of (i) stock options, including incentive stock options (or “ISOs”) entitling the optionee to favorable tax treatment under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), (ii) stock appreciation rights (“SARs”), (iii) restricted stock, (iv) restricted stock units (“RSUs”), (iv) performance awards, and (v) other awards valued in whole or in part by reference to or otherwise based on our common stock (“Other Stock-Based Awards”). Each type of award is described below under “Types of Awards Under the Plan.” Each of the awards will be evidenced by an award document setting forth the applicable terms and conditions.

We believe that we have demonstrated a commitment to sound equity compensation practices in recent years. We recognize that equity compensation awards dilute shareholder equity, so we have carefully managed our equity incentive compensation. Our equity compensation practices are intended to be competitive and consistent with market practices, and we believe our historical share usage has been responsible and mindful of stockholder interests.

Equity Compensation Information

As of April 1, 2022, only 6,005 shares remained available for issuance under the 2020 Plan. If the Plan is not approved, we will be compelled to increase significantly the cash component of our employee compensation, which may not align employee compensation interests with the investment interests of our stockholders, which alignment is best achieved through equity-based awards.

40

As of April 1, 2022, there were 1,443,157 restricted shares outstanding and a total of 1,029,365 stock options outstanding, with a weighted average exercise price of $12.64 and a weighted remaining term of 6.49 years. As of April 1, 2022, there were 484,585 performance-based stock units granted, which includes both earned and unearned performance-based stock units.

If the Plan is approved, 2,450,000 shares will be available for grant under the Plan, plus the number of shares remaining available for issuance under the 2020 Plan as of immediately prior to the Effective Date. If the Plan is approved, no future awards will be granted under the 2020 Plan following the Effective Date. Although no new awards will be granted under the 2020 Plan following the Effective Date if the Plan is approved, shares that again become available for awards under the 2017 Plan and the 2020 Plan pursuant to the terms of the 2017 Plan and the 2020 Plan, as applicable, will become available for awards under the Plan. Based on the closing price for our common stock on April 1, 2022 of $8.15 per share, the aggregate market value as of April 1, 2022 of the 2,450,000 new shares proposed to be issued under the Plan was $19,967,500.

“Dilution” is measured as the total number of shares under all outstanding equity awards (i.e., share awards granted, less share award cancellations), as a percentage of the weighted basic average number of shares of common stock and warrants outstanding for that year. Over the past three years, our average annual dilution was 5.57%, 7.25% and 10.14% (for 2019, 2020 and 2021, respectively).

Our “burn rate” measures the number of shares under outstanding equity awards granted during a given year (disregarding cancellations), as a percentage of the weighted basic average number of shares of common stock and warrants outstanding for that year. It measures the potential dilutive effect of annual equity grants. Over the past three years, the burn rate was of 2.15%, 2.47% and 4.07% (for 2019, 2020 and 2021, respectively). We believe that our three-year average burn rate is within the levels recommended by shareholder advisory groups on an overall basis when taking into account our business lines in multiple industry classifications.

If the Plan is approved, we intend to utilize the shares authorized under the Plan to continue our practice of incentivizing key individuals through annual equity grants. Based on our current projections, we anticipate that the shares requested under the Plan will last for approximately three years.

Plan Highlights

Double-Trigger Vesting. The Plan contains a so-called “double-trigger” vesting provision, which generally provides that awards will not be accelerated upon a change of control of the Company if (i) an acquiror replaces or substitutes outstanding awards in accordance with the requirements of the Plan and (ii) a participant holding the replacement or substitute award is not involuntarily terminated within two years following the change of control.

41

Independent Plan Administrator. The Compensation Committee, which is composed of independent directors, administers the Plan, and retains full discretion to determine the number and amount of awards to be granted under the Plan, subject to the terms of the Plan.

Reasonable Plan Limits. Subject to adjustment as described in the Plan, the number of shares available for grant under the Plan is limited to 2,450,000 shares of our common stock, plus the number of shares remaining available for issuance under the 2020 Plan as of immediately prior to the Effective Date, plus any shares that again become available for issuance under the Plan, the 2020 Plan or the 2017 Plan, in accordance with the terms of the applicable plan. These shares may be shares of original issuance or treasury shares or a combination of the foregoing. If the Plan is approved, no future awards will be granted under the 2020 Plan following the Effective Date.

The Plan also provides that, subject to adjustment as described in the Plan:

Stockholder Approval of Material Amendments. The Plan requires us to seek stockholder approval for any material amendments to the Plan, such as materially increasing benefits accrued to participants and materially increasing the number of shares available.

Prohibition on the Repricing of Options and SARs. The Plan prohibits the repricing of outstanding stock options or SARs without stockholder approval (outside of certain corporate transactions or adjustment events described in the Plan). We have never repriced underwater stock options or SARs.

No Transfers of Awards for Value. The Plan requires that no awards granted under the Plan may be transferred for value, subject to exceptions for certain familial transfers.

No Discounted Stock Options or SARs. The Plan requires that the exercise price for newly-issued stock options or SARs be at least 100% of the per share “fair market value” (as defined in the Plan) on the date of grant.

Prohibition of Dividends or Dividend Equivalents on Unvested Awards. The Plan prohibits the current payment of dividends or dividend equivalents with respect to shares underlying awards prior to the date on which the award has vested. Any such dividends or dividend equivalents will be deferred until and contingent upon the vesting of the underlying award.

Prohibition on Liberal Share Counting. The Plan does not permit adding back to the shares of common stock available for issuance under the Plan shares that were tendered or withheld to pay the exercise price of stock options or other awards or to cover withholding obligations. Any shares that are purchased by the Company in the open market pursuant to any repurchase plan or program, whether using option proceeds or otherwise, will not be made available for grants of awards under the Plan and will not increase the number of Shares available for future grant under the Plan.

Purpose

The Plan authorizes the Compensation Committee, or another committee designated by the Board and made up of two or more non-employee directors (as applicable, the “Committee”), to provide equity-based or other incentive-based compensation for the purpose of attracting and retaining directors, employees and certain consultants and providing our directors, employees and such consultants incentives and rewards for superior performance.

42

Shares Subject to the Plan

The Board has authorized the issuance of 2,450,000 new shares of our common stock in connection with awards pursuant to the Plan, plus the number of shares of our common stock remaining available for issuance under the 2020 Plan as of immediately prior to the Effective Date. If the Plan is approved, no future awards will be granted under the 2020 Plan following the Effective Date. However, any shares that again become available for issuance under the 2017 Plan and the 2020 Plan, in accordance with the terms of those plans, as applicable, will become available for issuance under the Plan. No more than 2,000,000 of the total number of shares available for issuance under the Plan may be issued upon the exercise of ISOs. The number of shares with respect to awards (including options and SARs) that may be granted under the Plan to any individual participant in respect of a single fiscal year may not exceed 624,000 shares, and the number of shares with respect to awards (including options and SARs) that may be granted under the Plan to any individual non-employee member of the Board may not exceed 217,400 shares, each as subject to potential adjustment as described in the Plan.

Any shares of our common stock covered by an award granted under the Plan, which for any reason is canceled, forfeited or expires or, in the case of an award other than a stock option, is settled in cash, will again be available for awards under the Plan. However, (i) shares not issued or delivered as a result of the net settlement of an outstanding stock option or SAR and (ii) shares used to pay the exercise price or withholding taxes related to an outstanding award may not again be made available for delivery to participants under the Plan.

Subject to the Plan’s share counting rules, common stock covered by awards granted under the Plan will not be counted as used unless and until the shares are actually issued or transferred. However, common stock issued or transferred under awards granted under the Plan in substitution for or conversion of, or in connection with an assumption of, stock options, SARs, restricted stock, RSUs or other stock or stock-based awards held by awardees of an entity engaging in a corporate acquisition or merger transaction with us or any of our subsidiaries will not count against (or be added back to) the aggregate share limit or other Plan limits described above. Additionally, shares available under certain plans that we or our subsidiaries may assume in connection with corporate transactions from another entity may be available for certain awards under the Plan, under circumstances further described in the Plan, but will not count against the aggregate share limit or other Plan limits described above. The various limits described above are subject to potential adjustment as described in the Plan.

Plan Administration

The Plan is administered by the Committee. The Committee generally may select eligible employees to whom awards are granted, determine the types of awards to be granted and the number of shares covered by awards and set the terms and conditions of awards. The Committee’s determinations and interpretations under the Plan will be binding on all interested parties. The Committee may delegate to a subcommittee or to officers certain authority with respect to the granting of awards other than awards to certain officers and directors as specified in the Plan.

Eligibility

Awards may be made by the Committee to any of our employees or certain qualifying consultants, or to employees or certain qualifying consultants of our affiliates, or non-employee directors who are members of the Board or the board of directors of our affiliates; provided that ISOs may only be granted to our employees or employees of our affiliates. Currently, there are 1,644 individuals whom we believe would be eligible to participate in the Plan subject to any necessary approvals by the Committee, consisting of six officers, 1,634 employees, and four non-employee directors.

No Repricing Without Shareholder Approval

Except in connection with a corporate transaction or other adjustment event described in the Plan, repricing of underwater options and SARs is prohibited without stockholder approval under the Plan.

43

Types of Awards Under the Plan

Stock Options. Option rights may be granted that entitle the optionee to purchase shares of our common stock at a price not less than (except with respect to Substitute Awards described below) fair market value at the date of grant, and may be ISOs, nonqualified stock options, or combinations of the two. Stock options granted under the Plan will be subject to such terms and conditions, including exercise price and conditions and timing of exercise, as may be determined by the Committee and specified in the applicable award agreement. Payment in respect of the exercise of an option granted under the Plan may be made (i) in cash or its equivalent, or (ii) in the discretion of the Committee, by exchanging shares owned by the optionee (which are not the subject of any pledge or other security interest and which have been owned by such optionee for at least six months), or (iii) in the discretion of the Committee and subject to such rules as may be established by the Committee and applicable law, either through delivery of irrevocable instructions to a broker to sell the shares being acquired upon exercise of the option and to deliver promptly to us an amount equal to the aggregate exercise price or (iv) in the discretion of the Committee and subject to any conditions or limitations established by the Committee, by having us withhold from shares otherwise deliverable an amount equal to the aggregate option exercise price, or (v) by a combination of the foregoing, or (vi) by such other methods as may be approved by the Committee, provided that the combined value of all cash and cash equivalents and the fair market value of such shares so tendered to us or withheld as of the date of such tender or withholding is at least equal to the aggregate exercise price of the option. No stock option may be exercisable more than 10 years from the date of grant.

Stock Appreciation Rights. SARs granted under the Plan will be subject to such terms and conditions, including grant price and the conditions and limitations applicable to exercise thereof, as may be determined by the Committee and specified in the applicable award agreement. SARs may be granted in tandem with another award, in addition to another award, or freestanding and unrelated to another award. A SAR will entitle the participant to receive an amount equal to the excess of the fair market value of a share on the date of exercise of the SAR over the grant price thereof (which may not be (except with respect to Substitute Awards described below) less than fair market value on the date of grant). The Committee, in its sole discretion, will determine whether a SAR will be settled in cash, shares or a combination of cash and shares. No SAR may be exercisable more than 10 years from the date of grant. At the discretion of the Committee, SARs may, but need not be, intended to qualify as performance-based compensation

Restricted Stock and Restricted Stock Units. Restricted stock and RSUs granted under the Plan will be subject to such terms and conditions, including the duration of the period during which, and the conditions, if any, under which, the restricted stock and restricted stock units may be forfeited to us, as may be determined by the Committee in its sole discretion. Each RSU will have a value equal to the fair market value of a share of our common stock. RSUs will be paid in cash, shares, other securities or other property, as determined by the Committee in its sole discretion, upon or after the lapse of the restrictions applicable thereto or otherwise in accordance with the applicable award agreement. Dividends paid on any Restricted Stock or dividend equivalents paid on any RSUs will be withheld by us, subject to vesting of the Restricted Stock or RSUs under the terms of the applicable award agreement.

Performance Awards. Performance awards granted under the Plan will consist of a right which is (i) denominated in cash or shares, (ii) valued, as determined by the Committee, in accordance with the achievement of such performance goals during such performance periods as the Committee will establish, and (iii) payable at such time and in such form as the Committee will determine. Subject to the terms of the Plan and any applicable award agreement, the Committee will determine the performance goals to be achieved during any performance period, the length of any performance period, the amount of any performance award and the amount and kind of any payment or transfer to be made pursuant to any performance award. Performance awards may be paid in a lump sum or in installments following the close of the performance period (as set forth in the applicable award agreement) or, in accordance with procedures established by the Committee, on a deferred basis. The Committee may require or permit the deferral of the receipt of performance awards upon such terms as the Committee deems appropriate and in accordance with Section 409A of the Code.

44

Other Stock-Based Awards. In addition to the foregoing types of awards, the Committee will have authority to grant to participants an “other stock-based award” (as defined in the Plan), which will consist of any right which is (i) not a stock option, SAR, restricted stock or RSU or performance award and (ii) an award of shares or an award denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, shares of our common stock (including, without limitation, securities convertible into shares of our common stock), as deemed by the Committee to be consistent with the purposes of the Plan; provided that any such rights must comply, to the extent deemed desirable by the Committee, with Rule 16b-3 and applicable law. Subject to the terms of the Plan and any applicable award agreement, the Committee will determine the terms and conditions of any such other stock-based award, including the price, if any, at which securities may be purchased pursuant to any other stock-based award granted under the Plan.

Dividends; Dividend Equivalents. In the sole discretion of the Committee, an award (other than options or SARs), whether made as another stock-based award or as any other type of award issuable under the Plan, may provide the participant with the right to receive dividends or dividend equivalents, payable in cash, shares, other securities or other property. However, for awards that are subject to vesting conditions, dividends and dividend equivalents may be paid only on a deferred basis, subject to the vesting of the underlying award.

Performance Criteria

The Plan allows the Committee to establish measurable “Performance Criteria” for purposes of any award under the Plan that are intended to be performance-based. The Performance Criteria that will be used to establish such performance goal(s) may be based on one or more, or a combination of, the following in addition to any other metrics adopted by the Committee: (i) return on net assets; (ii) pretax income before allocation of corporate overhead and bonus; (iii) budget; (iv) net income; (v) division, group or corporate financial goals; (vi) return on stockholders’ equity; (vii) return on assets; (viii) return on capital; (ix) revenue; (x) profit margin; (xi) earnings per Share; (xii) net earnings; (xiii) operating earnings; (xiv) free cash flow; (xv) attainment of strategic and operational initiatives; (xvi) appreciation in and/or maintenance of the price of the Shares or any other publicly-traded securities of the Company; (xvii) market share; (xviii) gross profits; (xix) earnings before interest and taxes; (xx) earnings before interest, taxes, depreciation and amortization; (xxi) operating expenses; (xxii) capital expenses; (xxiii) enterprise value; (xxiv) equity market capitalization; (xxv) sales; (xxvi) net sales; (xxvii) market share; (xxviii) economic value-added models and comparisons with various stock market indices; or (xxix) reductions in costs.

Amendments

The Board may amend the Plan from time to time without further approval by our stockholders, except where (i) the amendment would materially increase the benefits accruing to participants under the Plan, (ii) the amendment would materially increase the number of securities which may be issued under the Plan, or (iii) stockholder approval is required by applicable law or securities exchange rules and regulations, and provided that no such action that would adversely affect the rights of any participant with respect to awards previously granted under the Plan will be effective without the participant’s consent.

Transferability

Each award, and each right under any award, will be exercisable only by the participant during the participant’s lifetime, or, if permissible under applicable law, by the participant’s guardian or legal representative, and no award may be sold, assigned, pledged, attached, alienated or otherwise transferred or encumbered by a participant, other than by will or by the laws of descent and distribution, and any such purported sale, assignment, pledge, attachment, alienation, transfer or encumbrance will be void and unenforceable against us or any affiliate; provided that the designation of a beneficiary will not constitute a sale, assignment, pledge, attachment, alienation, transfer or encumbrance. In no event will any award granted under the Plan be transferred for value. However, the Committee may permit the transferability of an award under the Plan by a participant to certain members of the participant’s immediate family or trusts for the benefit of such persons or other entities owned by such persons

45

Adjustments

The number and kind of shares covered by outstanding awards and available for issuance or transfer (and Plan limits) under the Plan and, if applicable, the prices per share applicable thereto, are subject to adjustment in the event of dividend or other distribution (whether in the form of cash, shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of shares or other securities of ours, issuance of warrants or other rights to purchase our shares or other securities, or other corporate transaction or event. In the event of any such transaction, the Committee may, in its discretion, adjust to prevent dilution or enlargement of benefits (i) the number of our shares or other securities (or number and kind of other securities or property) with respect to which awards may be granted, (ii) the number of our shares or other securities of (or number and kind of other securities or property) subject to outstanding awards, and (iii) the grant or exercise price with respect to any award or, if deemed appropriate, make provision for a cash payment to the holder of an outstanding award in consideration for the cancellation of such award, which, in the case of options and SARs will equal the excess, if any, of the fair market value of the shares subject to such options or SARs over the aggregate exercise price or grant price of such options or SARs. However, such adjustment to the Plan limits will be made only if and to the extent that such adjustment would not cause any ISO to fail to so qualify.

Change of Control

Unless a Replacement Award (as defined in the Plan) is provided to the participant, in the event of a Change of Control (as defined in the Plan), unless otherwise (i) determined by the Committee at the date of grant, (ii) set forth in the applicable award agreement, or (iii) provided in an individual severance or employment agreement to which a participant is a party, each then-outstanding option and SAR will become fully vested and exercisable and the restrictions applicable to each outstanding restricted stock award, restricted stock unit award, performance award or other stock-based award will lapse and the award will be fully vested (with any applicable performance goals deemed to have been achieved at a target level as of the date of such vesting).

With respect to a Replacement Award, upon the Involuntary Termination (as defined in the Plan) of a participant holding such Replacement Award during the period of two years after a Change of Control, (a) all Replacement Awards held by the participant will become fully vested and, if applicable, exercisable and free of restrictions (with any applicable performance goals deemed to have been achieved at a target level as of the date of such vesting), and (b) all options and SARs held by the participant immediately before such termination of employment that the participant also held as of the date of the Change of Control or that constitute Replacement Awards will remain exercisable for a period of 90 days following such Involuntary Termination or until the expiration of the stated term of such option or SAR, whichever period is shorter (subject to any longer period of exercisability that may be provided in the applicable award agreement).

Withholding Taxes

A participant may be required to pay to us, and, subject to Section 409A of the Code, we will have the right and are authorized to withhold from any award, from any payment due or transfer made under any award or under the Plan or from any compensation or other amount owing to a participant the amount (in cash, shares, other securities, other awards or other property) of any applicable withholding taxes in respect of an award, its exercise, or any payment or transfer under an award or under the Plan and to take such other action as may be necessary in our opinion to satisfy all obligations for the payment of such taxes. In the discretion of the Committee and subject to such rules as the Committee may adopt, a participant may satisfy, in whole or in part, the withholding liability by delivery of shares owned by the participant (which are not subject to any pledge or other security interest and which have been owned by the participant for at least six months) with a fair market value equal to such withholding liability or by having us withhold from the number of shares otherwise issuable upon the occurrence of a vesting event a number of shares with a fair market value equal to such withholding liability.

Detrimental Activity and Recapture Provisions

Any award agreement may provide for the cancellation or forfeiture of an award or the forfeiture and repayment of any gain related to an award, or other provisions intended to have a similar effect, upon terms

46

and conditions determined by the Committee, if a participant, either during (i) his or her employment or other service with us or an affiliate or (ii) within a specific period after termination of employment or service, engages in any “detrimental activity” (as defined in such award agreement). In addition, any award agreement may provide for the cancellation or forfeiture of an award or the forfeiture and repayment to us of any gain related to an award, or other provisions intended to have a similar effect, upon such terms and conditions as may be determined by the Committee from time to time or under Section 10D of the Securities Exchange Act of 1934, as amended, or the rules of any national securities exchange or national securities association on which our common stock is traded.

Termination

No grant will be made under the Plan more than 10 years after the Effective Date, but all grants made on or prior to such date will continue in effect thereafter subject to the terms thereof and of the Plan.

Federal Income Tax Consequences Relating to Awards

The following is a brief summary of some of the federal income tax consequences of certain transactions under the Plan based on federal income tax laws in effect on the date hereof. This summary, which is presented for the information of stockholders considering how to vote on this proposal and not for Plan participants, is not intended to be complete and does not describe federal taxes other than income taxes (such as Medicare and Social Security taxes), or state, local or foreign tax consequences. The following is not to be considered as tax advice to any persons who may be participants in the Plan, and any such persons are advised to consult with their own tax counsel.

Tax Consequences to Participants

Non-qualified Stock Options. In general, (i) no income will be recognized by an optionee at the time a non-qualified stock option is granted; (ii) at the time of exercise of a non-qualified stock option, ordinary income will be recognized by the optionee in an amount equal to the difference between the option price paid for the shares and the fair market value of the shares, if unrestricted, on the date of exercise; and (iii) at the time of sale of shares acquired pursuant to the exercise of a non-qualified stock option, appreciation (or depreciation) in value of the shares after the date of exercise will be treated as either short-term or long-term capital gain (or loss), depending on how long the shares have been held.

Incentive Stock Options. No income generally will be recognized by an optionee upon the grant or exercise of an ISO. The exercise of an ISO, however, may result in alternative minimum tax liability. If shares of our common stock are issued to the optionee pursuant to the exercise of an ISO, and if no disqualifying disposition of such shares is made by such optionee within two years after the date of grant or within one year after the transfer of such shares to the optionee, then upon sale of such shares, any amount realized in excess of the option price will be taxed to the optionee as a long-term capital gain and any loss sustained will be a long-term capital loss.

If shares of our common stock acquired upon the exercise of an ISO are disposed of prior to the expiration of either holding period described above, the optionee generally will recognize ordinary income in the year of disposition in an amount equal to the excess (if any) of the fair market value of such shares at the time of exercise (or, if less, the amount realized on the disposition of such shares if a sale or exchange) over the option price paid for such shares. Any further gain (or loss) realized by the participant generally will be taxed as short-term or long-term capital gain (or loss), depending on the holding period.

Stock Appreciation Rights. No income will be recognized by a participant in connection with the grant of a tandem SAR or a free-standing SAR. When the SAR is exercised, the participant normally will be required to include as taxable ordinary income in the year of exercise an amount equal to the amount of cash received and the fair market value of any unrestricted shares of our common stock received on the exercise.

Restricted Stock. The recipient of restricted stock generally will be subject to tax at ordinary income rates on the fair market value of the restricted stock (reduced by any amount paid by the participant for such

47

restricted stock) at such time as the shares are no longer subject to forfeiture or restrictions on transfer for purposes of Section 83 of the Code (“Restrictions”). However, a recipient who so elects under Section 83(b) of the Code within 30 days of the date of transfer of the shares will have taxable ordinary income on the date of transfer of the shares equal to the excess of the fair market value of such shares (determined without regard to the Restrictions) over the purchase price, if any, of such restricted stock. If a Section 83(b) election has not been made, any dividends received with respect to restricted stock that is subject to the Restrictions generally will be treated as compensation that is taxable as ordinary income to the participant.

Restricted Stock Units. No income generally will be recognized upon the award of RSUs. The recipient of an RSU award generally will be subject to tax at ordinary income rates on the fair market value of unrestricted shares of our common stock on the date that such shares are transferred to the participant under the award (reduced by any amount paid by the participant for such RSUs), and the capital gains/loss holding period for such shares will also commence on such date.

Performance Awards. No income generally will be recognized upon the grant of performance awards. Upon payment in respect of the earn-out of performance awards, the recipient generally will be required to include as taxable ordinary income in the year of receipt an amount equal to the amount of cash received and the fair market value of any unrestricted shares of our common stock received.

Tax Consequences to Us or Our Subsidiaries

To the extent that a participant recognizes ordinary income in the circumstances described above, we or the subsidiary for which the participant performs services will be entitled to a corresponding deduction, provided that, among other things, the income meets the test of reasonableness, is an ordinary and necessary business expense, is not an “excess parachute payment” within the meaning of Section 280G of the Code and is not disallowed by the $1 million limitation on certain executive compensation under Section 162(m) of the Code.

Compliance with Section 409A of the Code

To the extent applicable, it is intended that the Plan and any grants made thereunder comply with the provisions of Section 409A of the Code, so that the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to the participants. The Plan and any grants made under the Plan will be administered in a manner consistent with this intent. Any reference in the Plan to Section 409A of the Code will also include any regulations or any other formal guidance promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service.

Registration with the SEC

We intend to file a Registration Statement on Form S-8 relating to the issuance of shares of our common stock under the Plan with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended, as soon as is practicable after approval of the Plan by our stockholders.

New Plan Benefits

Because awards to be granted in the future under the Plan are at the discretion of the Committee, it is not possible to determine the benefits or the amounts to be received (or that would have been received had the Plan been in effect for the last fiscal year) under the Plan by our directors, officers or employees.

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, 2022. 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.

Independent Registered Public Accounting Firm Fee Information

Fees for professional services provided by Grant Thornton LLP for the years ended December 31 were as follows:

Audit Fees represent fees for professional services provided in connection with the audit of the Company’s financial statements, review of the Company’s quarterly financial statements, and services provided in connection with other statutory or regulatory filings. Audit-Related Fees represent fees for professional services provided in consulting on interpretations and application of FASB pronouncements and SEC regulations. Tax Fees represent fees for services in connection with the preparation and filing of tax returns in jurisdictions outside the United States. All Other Fees primarily include labor law certification services provided to the Company’s foreign subsidiaries in accordance with local requirements.

49

The Audit Committee has determined that the provision of the services described above is compatible with maintaining the independence of our independent registered public accountants. All services described in the foregoing table were approved in conformity with the Audit Committee’s pre-approval process.

Pre-approval Policy for Services of Independent Registered Public Accounting Firm. The Audit Committee’s policy is to pre-approve all audit services, audit-related services and other services permitted by law provided by the independent registered public accounting firm. In accordance with that policy, the Audit Committee annually reviews and approves a list of specific services and categories of services, including audit, audit related, tax, and other permitted services, for the current or upcoming fiscal year, subject to specified terms and cost levels. Any service not included in the approved list of services or any modification to previously approved services, including changes in fees, must be specifically pre-approved by the Audit Committee. Where proposed additions or modifications relate to tax and all other non-audit services to be provided by the independent registered public accounting firm, the Audit Committee may delegate the responsibility of pre-approval to the chairperson of the Audit Committee. To ensure prompt handling of unforeseeable or unexpected matters that arise between Audit Committee meetings, the Audit Committee has delegated authority to its chairperson, and/or to such other members of the Audit Committee that the chairperson may designate, to review and if appropriate approve in advance, any request by the independent registered public accounting firm to provide tax and/or all other non-audit services.

Audit Committee Report

In connection with the Company’s consolidated financial statements for the year ended December 31, 2021, the Audit Committee has:

Based on the review and discussions with the Company’s management and the independent registered public accounting firm, as set forth above, the Audit Committee recommended to the Board that the audited financial statements be included in the Company’s 2021 Annual Report, for filing with the SEC.

The foregoing report is respectfully submitted by the members of the Audit Committee at the time of the recommendation.

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.

ANNUAL REPORT

A copy of the Company’s 2021 Annual Report accompanies this Proxy Statement and should be read in conjunction herewith.

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

51

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 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.

52

STOCKHOLDER PROPOSALS FOR THE 2023 ANNUAL MEETING

Proposals that stockholders believe should be voted upon at the Company’s Annual Meeting 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 2023 Annual Meeting of Stockholders must be received by the Company on or before January 4, 2023, to be eligible for inclusion in the proxy statement and proxy card relating to the 2023 Annual Meeting of Stockholders, unless the Company determines to hold the meeting more than 30 days before or after the anniversary of the 2022 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 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.

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 2021 Annual Report and this Proxy Statement to a stockholder at a shared address to which a single copy of the documents was delivered.

For the Board of Directors,

Andrew H. Everett II

Senior Vice President

General Counsel and Secretary

(c) The mere fact that a Committee member shall fail to qualify as a “Non-Employee Director” within the meaning of Rule 16b-3 shall not invalidate any Award otherwise validly made by the Committee under the Plan. Notwithstanding anything in this Section 3 to the contrary, the Board, or any other committee or sub-committee established by the Board, is hereby authorized (in addition to any necessary action by the Committee) to grant or approve Awards as necessary to satisfy the requirements of Section 16 of the Exchange Act and the rules and regulations thereunder and, to the extent permitted by applicable law, to act in lieu of the Committee with respect to Awards made to non-employee directors under the Plan.

(d) No member of the Board or the Committee and no employee of the Company or any Affiliate shall be liable for any determination, act or failure to act hereunder (except in circumstances involving his or her bad faith), or for any determination, act or failure to act hereunder by any other member or employee or by any agent to whom duties in connection with the administration of the Plan have been delegated.

The Committee may employ such legal or other counsel, consultants and agents as it may deem desirable for the administration of the Plan and may rely upon any opinion or computation received from any such counsel, consultant or agent.

A-5

Section 4. Shares Available for Awards.

(a) Shares Available.

(i) Subject to adjustment as provided in Section 4(b), the aggregate number of Shares with respect to which Awards may be granted from time to time under the Plan shall in the aggregate not exceed, at any time, the sum of (A) 2,450,000 Shares, plus (B) the number of shares of common stock remaining available for awards under the 2020 Plan as of immediately prior to the Effective Date, plus (C) any Shares that again become available for Awards under the Plan in accordance with Section 4(a)(ii) and any shares of common stock that again become available for awards under the 2017 Plan or the 2020 Plan, in accordance with the terms of the 2017 Plan and 2020 Plan, as applicable. Subject to adjustment as provided in Section 4(b), the aggregate number of Shares with respect to which Incentive Stock Options may be granted under the Plan shall be 2,000,000 Shares. Subject in each instance to adjustment as provided in Section 4(b), the maximum number of Shares with respect to which Awards may be granted to any single Participant in respect of any fiscal year shall be 624,000 Shares, and the maximum number of Shares with respect to which Awards may be granted to any single non-employee member of the Board in respect of any fiscal year shall be 217,400 Shares.

(ii) Shares covered by an Award granted under the Plan shall not be counted unless and until they are actually issued and delivered to a Participant and, therefore, the total number of Shares available under the Plan as of a given date shall not be reduced by Shares relating to prior Awards that (in whole or in part) have expired or have been forfeited or cancelled and upon payment in cash of the benefit provided by any Award, any Shares that were covered by such Award will be available for issue hereunder. For the avoidance of doubt, the following Shares shall not again be made available for delivery to Participants under the Plan: (A) Shares not issued or delivered as a result of the net settlement of an outstanding Option or Stock Appreciation Right, and (B) Shares tendered or withheld to pay the exercise price or withholding taxes related to an outstanding Award. Any Shares that are purchased by the Company in the open market pursuant to any repurchase plan or program, whether using Option proceeds or otherwise, shall not be made available for grants of Awards under the Plan and shall not increase the number of Shares available for future grant under the Plan.

(b) Adjustments. Notwithstanding any provisions of the Plan to the contrary, in the event that the Committee determines in its sole discretion that any dividend or other distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, issuance of warrants or other rights to purchase Shares or other securities of the Company, or other corporate transaction or event that, in each case, affects the Shares such that an adjustment is appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, then the Committee shall equitably adjust any or all of (i) the number of Shares or other securities of the Company (or number and kind of other securities or property) with respect to which Awards may be granted under the Plan, (ii) the number of Shares or other securities of the Company (or number and kind of other securities or property) subject to outstanding Awards, and (iii) the grant or exercise price with respect to any Award or, if deemed appropriate, make provision for a cash payment to the holder of an outstanding Award in consideration for the cancellation of such Award, which, in the case of Options and Stock Appreciation Rights shall equal the excess, if any, of the Fair Market Value of the Share subject to each such Option or Stock Appreciation Right over the per Share exercise price or grant price of such Option or Stock Appreciation Right. The Committee will also make or provide for such adjustments in the numbers of Shares specified in Section 4(a)(i) of the Plan as the Committee in its sole discretion, exercised in good faith, may determine is appropriate to reflect any transaction or event described in this Section 4(b); provided, however, that any such adjustment to the numbers specified in Section 4(a)(i) of the Plan will be made only if and to the extent that such adjustment would not cause any Option intended to qualify as an Incentive Stock Option to fail to so qualify.

(c) Substitute Awards.

(i) Awards may be granted under the Plan in substitution for or in conversion of, or in connection with an assumption of, stock options, stock appreciation rights, restricted stock, restricted stock units or other stock or

A-6

stock-based awards held by awardees of an entity engaging in an acquisition or merger transaction with the Company or any subsidiary of the Company. Any conversion, substitution or assumption will be effective as of the close of the merger or acquisition, and, to the extent applicable, will be conducted in a manner that complies with Section 409A of the Code.

(ii) In the event that an entity acquired by the Company or any subsidiary of the Company, or with which the Company or any subsidiary of the Company merges, has shares available under a pre-existing plan previously approved by stockholders and not adopted in contemplation of such acquisition or merger, the shares available for grant pursuant to the terms of such plan (as adjusted, to the extent appropriate, to reflect such acquisition or merger) may be used for Awards made after such acquisition or merger under the Plan; provided, however, that Awards using such available shares may not be made after the date awards or grants could not have been made under the terms of the pre-existing plan absent the acquisition or merger, and may only be made to individuals who were not employees or directors of the Company or any subsidiary of the Company prior to such acquisition or merger. The Awards so granted may reflect the original terms of the awards being assumed or substituted or converted for and need not comply with other specific terms of the Plan, and may account for Shares substituted for the securities covered by the original awards and the number of shares subject to the original awards, as well as any exercise or purchase prices applicable to the original awards, adjusted to account for differences in stock prices in connection with the transaction.

(iii) Any Shares that are issued or transferred by, or that are subject to any Awards that are granted by, or become obligations of, the Company under Sections 4(c)(i) or 4(c)(ii) of the Plan will not reduce the Shares available for issuance or transfer under the Plan or otherwise count against the limits described in Section 4(a)(i) of the Plan. In addition, no Shares that are issued or transferred by, or that are subject to any Awards that are granted by, or become obligations of, the Company under Sections 4(c)(i) or 4(c)(ii) of the Plan will be added to the aggregate limit described in Section 4(a)(i) of the Plan.

(d) Sources of Shares Deliverable Under Awards. Any Shares delivered pursuant to an Award may consist, in whole or in part, of authorized and unissued Shares or of treasury Shares.

Section 5. Eligibility. Any employee of, or consultant to, the Company or any of its Affiliates (including, but not limited to, any prospective employee), or non-employee director who is a member of the Board or the board of directors of an Affiliate, shall be eligible to be selected as a Participant.

Section 6. Stock Options.

(a) Grant. Subject to the terms of the Plan, the Committee shall have sole authority to determine the Participants to whom Options shall be granted, the number of Shares to be covered by each Option, the exercise price thereof and the conditions and limitations applicable to the exercise of the Option. The Committee shall have the authority to grant Incentive Stock Options, or to grant Non-Qualified Stock Options, or to grant both types of Options. In the case of Incentive Stock Options, the terms and conditions of such Awards shall be subject to and comply with such rules as may be prescribed by Section 422 of the Code and any regulations implementing such statute. All Options when granted under the Plan are intended to be Non-Qualified Stock Options, unless the applicable Award Agreement expressly states that the Option is intended to be an Incentive Stock Option. If an Option is intended to be an Incentive Stock Option, and if for any reason such Option (or any portion thereof) shall not qualify as an Incentive Stock Option, then, to the extent of such nonqualification, such Option (or portion thereof) shall be regarded as a Non-Qualified Stock Option appropriately granted under the Plan; provided that such Option (or portion thereof) otherwise complies with the Plan’s requirements relating to Non-Qualified Stock Options. No Option shall be exercisable more than ten years from the date of grant.

(b) Exercise Price. The Committee shall establish the exercise price at the time each Option is granted, which exercise price shall be set forth in the applicable Award Agreement and which exercise price (except with respect to Substitute Awards) shall not be less than the Fair Market Value per Share on the date of grant.

A-7

(c) Exercise. Each Option shall be exercisable at such times and subject to such terms and conditions as the Committee may, in its sole discretion, specify in the applicable Award Agreement. The Committee may impose such conditions with respect to the exercise of Options, including, without limitation, any relating to the application of federal or state securities laws, as it may deem necessary or advisable.

(d) Payment.

(i) No Shares shall be delivered pursuant to any exercise of an Option until payment in full of the aggregate exercise price therefor is received by the Company. Such payment may be made (A) in cash or its equivalent, (B) in the discretion of the Committee and subject to such rules as may be established by the Committee and applicable law, by exchanging Shares owned by the Participant (which are not the subject of any pledge or other security interest and which have been owned by such Participant for at least six months), (C) in the discretion of the Committee and subject to such rules as may be established by the Committee and applicable law, through delivery of irrevocable instructions to a broker to sell the Shares otherwise deliverable upon the exercise of the Option and to deliver promptly to the Company an amount equal to the aggregate exercise price, (D) in the discretion of the Committee and subject to such rules as may be established by the Committee and applicable law, by the Company’s withholding of Shares otherwise issuable upon exercise of an Option pursuant to a “net exercise” arrangement (it being understood that, solely for purposes of determining the number of treasury shares held by the Company, the Shares so withheld will not be treated as issued and acquired by the Company upon such exercise), (E) by a combination of the foregoing, or (F) by such other methods as may be approved by the Committee and subject to such rules as may be established by the Committee and applicable law, provided that the combined value of all cash and cash equivalents and the Fair Market Value of any such Shares so tendered to the Company or withheld as of the date of such tender or withholding is at least equal to such aggregate exercise price.

(ii) Wherever in the Plan or any Award Agreement a Participant is permitted to pay the exercise price of an Option or taxes relating to the exercise of an Option by delivering Shares, the Participant may, subject to procedures satisfactory to the Committee and applicable law, satisfy such delivery requirement by presenting proof of beneficial ownership of such Shares, in which case the Company shall treat the Option as exercised without further payment and shall withhold such number of Shares from the Shares acquired by the exercise of the Option.

Section 7. Stock Appreciation Rights.

(a) Grant. Subject to the provisions of the Plan, the Committee shall have sole authority to determine the Participants to whom Stock Appreciation Rights shall be granted, the number of Shares to be covered by each Stock Appreciation Right Award, the grant price thereof and the conditions and limitations applicable to the exercise thereof. Stock Appreciation Rights may be granted in tandem with another Award, in addition to another Award, or freestanding and unrelated to another Award. Stock Appreciation Rights granted in tandem with or in addition to an Award may be granted either before, at the same time as the Award or at a later time. No Stock Appreciation Right shall be exercisable more than ten years from the date of grant.

(b) Exercise and Payment. A Stock Appreciation Right shall entitle the Participant to receive an amount equal to the excess of the Fair Market Value of one Share on the date of exercise of the Stock Appreciation Right over the grant price thereof (which grant price (except with respect to Substitute Awards) shall not be less than the Fair Market Value on the date of grant). The Committee shall determine in its sole discretion whether a Stock Appreciation Right shall be settled in cash, Shares or a combination of cash and Shares.

Section 8. Restricted Stock and Restricted Stock Units.

(a) Grant. Subject to the provisions of the Plan, the Committee shall have sole authority to determine the Participants to whom shares of Restricted Stock and/or Restricted Stock Units shall be granted, the number of Shares of Restricted Stock and/or the number of Restricted Stock Units to be granted to each Participant, the

duration of the period during which, and the conditions, if any, under which, the Restricted Stock and Restricted Stock Units may vest and/or be forfeited to the Company, and the other terms and conditions of such Awards.

(b) Transfer Restrictions. Unless otherwise directed by the Committee, (i) certificates issued in respect of Shares of Restricted Stock shall be registered in the name of the Participant and deposited by such Participant, together with a stock power endorsed in blank, with the Company, or (ii) Shares of Restricted Stock shall be held at the Company’s transfer agent in book entry form with appropriate restrictions relating to the transfer of such Shares of Restricted Stock. Upon the lapse of the restrictions applicable to such Shares of Restricted Stock, the Company shall, as applicable, either deliver such certificates to the Participant or the Participant’s legal representative, or the transfer agent shall remove the restrictions relating to the transfer of such Shares. Shares of Restricted Stock and Restricted Stock Units may not be sold, assigned, transferred, pledged or otherwise encumbered, except as provided in the Plan or the applicable Award Agreement.

(c) Payment. Each Restricted Stock Unit shall have a value equal to the Fair Market Value of one Share. Restricted Stock Units shall be paid in cash, Shares, other securities or other property, as determined in the sole discretion of the Committee, upon or after the lapse of the restrictions applicable thereto, or otherwise in accordance with the applicable Award Agreement.

(d) Dividends; Dividend Equivalents. Any dividends payable on any Shares of Restricted Stock, or dividend equivalents paid on any Restricted Stock Units, shall be subject to the limitations set forth in Section 15(b) of the Plan.

Section 9. Performance Awards.

(a) Grant. The Committee shall have sole authority to determine the Participants who shall receive a Performance Award, which shall consist of a right which is (i) denominated in cash or Shares, (ii) valued, as determined by the Committee, in accordance with the achievement of the applicable Performance Criteria during such performance periods as the Committee shall establish, and (iii) payable at such time and in such form as the Committee shall determine.

(b) Terms and Conditions. Subject to the terms of the Plan and any applicable Award Agreement, the Committee shall determine the performance goals to be achieved during any performance period, the length of any performance period, the amount of any Performance Award and the amount and kind of any payment or transfer to be made pursuant to any Performance Award. The Committee may require or permit the deferral of the receipt of Performance Awards upon such terms as the Committee deems appropriate and in accordance with Section 409A of the Code.

(c) Payment of Performance Awards. Performance Awards may be paid in a lump sum or in installments following the close of the performance period, as set forth in the applicable Award Agreement.

Section 10. Other Stock-Based Awards. The Committee shall have authority to grant to Participants an Other Stock-Based Award, which shall consist of any right which is (i) not an Award described in Sections 6 through 9 of the Plan, and (ii) an Award of Shares or an Award denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, Shares (including, without limitation, securities convertible into Shares), as deemed by the Committee to be consistent with the purposes of the Plan; provided that any such rights must comply, to the extent deemed desirable by the Committee, with Rule 16b-3 and applicable law. Subject to the terms of the Plan and any applicable Award Agreement, the Committee shall determine the terms and conditions of any such Other Stock-Based Award, including, but not limited to, the price, if any, at which securities may be purchased pursuant to any Other Stock-Based Award granted under the Plan.

A-9

Section 11. Amendment and Termination.

(a) Amendments to the Plan. The Board may amend, alter, suspend, discontinue, or terminate the Plan or any portion thereof at any time; provided that if an amendment to the Plan (i) would materially increase the number of securities which may be issued under the Plan, or (ii) must otherwise be approved by the stockholders of the Company in order to comply with applicable law or the rules of the principal national securities exchange upon which the Shares are traded or quoted, such amendment will be subject to stockholder approval and no Shares will be issued in respect of such amendment unless and until such approval has been obtained; and provided, further, that any such amendment, alteration, suspension, discontinuance or termination that would impair the rights of any Participant or any holder or beneficiary of any Award previously granted shall not be effective without the written consent of the affected Participant, holder or beneficiary.

(b) Amendments to Awards. The Committee may waive any conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel or terminate, any Award theretofore granted; provided that any such waiver, amendment, alteration, suspension, discontinuance, cancellation or termination that would impair the rights of any Participant or any holder or beneficiary of any Award previously granted shall not be effective without the written consent of the affected Participant, holder or beneficiary.

(c) Adjustment of Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events. The Committee is hereby authorized to make equitable adjustments in the terms and conditions of, and the criteria included in, all outstanding Awards in recognition of unusual or nonrecurring events (including, without limitation, the events described in Section 4(b) hereof) affecting the Company, any Affiliate, or the financial statements of the Company or any Affiliate, or of changes in applicable laws, regulations, or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan.

(d) Repricing. Except in connection with a corporate transaction or event described in Section 4(b) hereof, the terms of outstanding Awards may not be amended to reduce the exercise price of Options or the grant price of Stock Appreciation Rights, or to cancel Options or Stock Appreciation Rights in exchange for cash, other Awards or Options or Stock Appreciation Rights with an exercise price or grant price, as applicable, that is less than the exercise price of the original Options or grant price of the original Stock Appreciation Rights, as applicable, without stockholder approval. This Section 11(d) is intended to prohibit the repricing of “underwater” Options and Stock Appreciation Rights and will not be construed to prohibit the adjustments provided for in Section 4(b) of the Plan.

Section 12. Change of Control.

Unless otherwise determined by the Committee in a written resolution upon or prior to the date of grant or set forth in an applicable Award Agreement, (i) the vesting of any Award that is a “Replaced Award” (as such term is defined below) will not be accelerated, and any applicable restrictions thereon will not lapse, solely as a result of a Change of Control; and (ii) in the event of a Change of Control, the following acceleration, exercisability and valuation provisions will apply:

(a) Upon a Change of Control, each then-outstanding Option and Stock Appreciation Right will become fully vested and exercisable, and the restrictions applicable to each outstanding Restricted Stock Award, Restricted Stock Unit Award, Performance Award or Other Stock-Based Award will lapse, and each Award will be fully vested (with any applicable performance goals or Performance Criteria deemed to have been achieved at target level as of the date of such vesting), except to the extent that an award meeting the requirements of Section 12(b) hereof (a “Replacement Award”) is provided to the Participant holding such Award in accordance with Section 12(b) hereof to replace or adjust such outstanding Award (a “Replaced Award”).

(b) An award meets the conditions of this Section 12(b) (and hence qualifies as a Replacement Award) if (i) it is of the same type (e.g., stock option for Option, restricted stock for Restricted Stock, restricted stock unit for Restricted Stock Unit, etc.) as the Replaced Award, (ii) it has a value at least equal to the value of the

A-10

Replaced Award, (iii) it relates to publicly traded equity securities of the Company or its successor in the Change of Control or another entity that is affiliated with the Company or its successor following the Change of Control, (iv) if the Participant holding the Replaced Award is subject to U.S. federal income tax under the Code, the tax consequences to such Participant under the Code of the Replacement Award are not less favorable to such Participant than the tax consequences of the Replaced Award, and (v) its other terms and conditions are not less favorable to the Participant holding the Replaced Award than the terms and conditions of the Replaced Award (including, but not limited to, the provisions that would apply in the event of a subsequent Change of Control). Without limiting the generality of the foregoing, the Replacement Award may take the form of a continuation of the Replaced Award if the requirements of the preceding sentence are satisfied. The determination of whether the conditions of this Section 12(b) are satisfied will be made by the Committee, as constituted immediately before the Change of Control, in its sole discretion (taking into account the requirements of Treasury Regulation 1.409A-3(i)(5)(iv)(B) and compliance of the Replaced Award or Replacement Award with Section 409A of the Code). Without limiting the generality of the foregoing, the Committee may determine the value of Awards and Replacement Awards that are stock options by reference to either their intrinsic value or their fair value.

(c) Upon the Involuntary Termination, during the period of two years immediately following a Change of Control, of a Participant holding Replacement Awards, (i) all Replacement Awards held by the Participant will become fully vested and, if applicable, exercisable and free of restrictions (with any applicable performance goals deemed to have been achieved at a target level as of the date of such vesting), and (ii) all Options and Stock Appreciation Rights held by the Participant immediately before such Involuntary Termination that the Participant also held as of the date of the Change of Control and all stock options and stock appreciation rights that constitute Replacement Awards will remain exercisable for a period of 90 days following such Involuntary Termination or until the expiration of the stated term of such stock option or stock appreciation right, whichever period is shorter (provided, however, that, if the applicable Award Agreement provides for a longer period of exercisability, that provision will control).

(d) Notwithstanding anything in the Plan or any Award Agreement to the contrary, to the extent that any provision of the Plan or an applicable Award Agreement would cause a payment of deferred compensation that is subject to Section 409A of the Code to be made upon the occurrence of (i) a Change of Control, then such payment shall not be made unless such Change of Control also constitutes a “change in control event” within the meaning of Section 409A of the Code and the regulatory guidance promulgated thereunder or (ii) a termination of employment or service, then such payment shall not be made unless such termination of employment or service also constitutes a “separation from service” within the meaning of Section 409A of the Code and the regulatory guidance promulgated thereunder. Any payment that would have been made except for the application of the preceding sentence shall be made in accordance with the payment schedule that would have applied in the absence of a Change of Control or termination of employment or service, but disregarding any future service and/or performance requirements.

Section 13. Non-U.S. Participants. In order to facilitate the granting of any Award or combination of Awards under the Plan, the Committee may provide for such special terms for awards to Participants who are foreign nationals or who are employed by the Company or any Affiliate outside of the United States of America or who provide services to the Company or an Affiliate under an agreement with a foreign nation or agency, as the Committee may consider necessary or appropriate to accommodate differences in local law, tax policy or custom. Moreover, the Committee may approve such supplements to or amendments, restatements or alternative versions of the Plan (including, without limitation, sub-plans) as it may consider necessary or appropriate for such purposes, without thereby affecting the terms of the Plan as in effect for any other purpose, and the Secretary or other appropriate officer of the Company may certify any such document as having been approved and adopted in the same manner as the Plan. No such special terms, supplements, amendments or restatements, however, will include any provisions that are inconsistent with the terms of the Plan as then in effect unless the Plan could have been amended to eliminate such inconsistency without further approval by the stockholders of the Company.

A-11

Section 14. Detrimental Activity and Recapture Provisions. Any Award Agreement may provide for the cancellation or forfeiture of an Award or the forfeiture and repayment to the Company of any gain related to an Award, or other provisions intended to have a similar effect, upon such terms and conditions as may be determined by the Committee from time to time, including, without limitation, in the event that a Participant, during employment or other service with the Company or an Affiliate, shall engage in activity detrimental to the business of the Company. In addition, notwithstanding anything in the Plan to the contrary, any Award Agreement may also provide for the cancellation or forfeiture of an Award or the forfeiture and repayment to the Company of any gain related to an Award, or other provisions intended to have a similar effect, upon such terms and conditions as may be required by the Committee or under Section 10D of the Exchange Act and any applicable rules or regulations promulgated by the SEC or any national securities exchange or national securities association on which the Shares may be traded or under any clawback policy adopted by the Company.

Section 15. General Provisions.

(a) Nontransferability.

(i) Each Award, and each right under any Award, shall be exercisable only by the Participant during the Participant’s lifetime, or, if permissible under applicable law, by the Participant’s legal guardian or representative.

(ii) No Award may be sold, assigned, alienated, pledged, attached or otherwise transferred or encumbered by a Participant otherwise than by will or by the laws of descent and distribution, and any such purported sale, assignment, alienation, pledge, attachment, transfer or encumbrance shall be void and unenforceable against the Company or any Affiliate; provided that the designation of a beneficiary shall not constitute a sale, assignment, alienation, pledge, attachment, transfer or encumbrance. In no event may any Award granted under the Plan be transferred for value.

(iii) Notwithstanding the foregoing, at the discretion of the Committee, an Award may be transferred by a Participant solely to the Participant’s spouse, siblings, parents, children and grandchildren or trusts for the benefit of such persons or partnerships, corporations, limited liability companies or other entities owned solely by such persons, including, but not limited to, trusts for such persons, subject to any restriction in the applicable Award Agreement.

(b) Dividends; Dividend Equivalents. In the sole discretion of the Committee, an Other Stock-Based Award or an Award granted pursuant to Sections 8 or 9 hereof, may provide the Participant with dividends or dividend equivalents, payable in cash, Shares, other securities or other property on a current or deferred basis; provided, that in the case of Awards with respect to which any applicable vesting conditions have not been satisfied, dividends and dividend equivalents shall only paid only on a deferred basis, to the extent the underlying Award vests. No dividends or dividend equivalents shall be payable in respect of Stock Appreciation Rights or Options that have not been settled in Shares.

(c) No Rights to Awards. No Participant or other Person shall have any claim to be granted any Award, and there is no obligation for uniformity of treatment of Participants, Awards, or holders or beneficiaries of Awards. The terms and conditions of Awards and the Committee’s determinations and interpretations with respect thereto need not be the same with respect to each or any Participant (whether or not such Participants are similarly situated).

(d) Share Certificates. Shares or other securities of the Company or any Affiliate delivered under the Plan pursuant to any Award or the exercise thereof shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan or the rules, regulations, and other requirements of the SEC, any stock exchange upon which such Shares or other securities are then listed, and any applicable Federal or state laws. The Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.

A-12

(e) Withholding.

(i) A Participant may be required to pay to the Company or any Affiliate, and, subject to Section 409A of the Code, the Company or any Affiliate shall have the right and is hereby authorized to withhold from any Award, from any payment due or transfer made under any Award or under the Plan or from any compensation or other amount owing to a Participant the amount (in cash, Shares, other securities, other Awards or other property) of any applicable withholding taxes in respect of an Award, its exercise, or any payment or transfer under an Award or under the Plan, and to take such other action(s) as may be necessary in the opinion of the Company to satisfy all obligations for the payment of such taxes.

(ii) Without limiting the generality of clause (i) above, in the discretion of the Committee and subject to such rules as it may adopt (including, without limitation, any as may be required to satisfy applicable tax and/or non-tax regulatory requirements) and applicable law, a Participant may satisfy, in whole or in part, the foregoing withholding liability by delivery of Shares owned by the Participant (which are not subject to any pledge or other security interest and which have been owned by the Participant for at least six months) with a Fair Market Value equal to such withholding liability or by having the Company withhold from the number of Shares otherwise issuable pursuant to the exercise of the Option (or the settlement of such Award in Shares) a number of Shares with a Fair Market Value equal to such withholding liability.

(f) Award Agreements. Each Award hereunder shall be evidenced by an Award Agreement, which shall be delivered to the Participant and shall specify the terms and conditions of the Award and any rules applicable thereto, including, but not limited to, the effect on such Award of the death, disability or termination of employment or service of a Participant and the effect, if any, of such other events as may be determined by the Committee.

(g) No Limit on Other Compensation Arrangements. Nothing contained in the Plan shall prevent the Company or any Affiliate from adopting or continuing in effect other compensation arrangements, which may, but need not, provide for the grant of options, restricted stock, restricted stock units, Shares and other types of Awards provided for hereunder (subject to stockholder approval if such approval is required), and such arrangements may be either generally applicable or applicable only in specific cases.

(h) No Right to Employment. The grant of an Award shall not be construed as giving a Participant the right to be retained in the employ of, or in any consulting or other service relationship to, or as a director on the Board or board of directors, as applicable, of, the Company or any Affiliate. Further, the Company or an Affiliate may at any time dismiss a Participant from employment or discontinue any consulting or other service relationship, free from any liability or any claim under the Plan or any Award Agreement, unless otherwise expressly provided in any applicable Award Agreement or any applicable employment or other service contract or agreement with the Company or an Affiliate.

(i) No Rights as Stockholder. Except as set forth in the applicable Award Agreement, no Participant or holder or beneficiary of any Award shall have any rights as a stockholder with respect to any Shares to be distributed under the Plan until he or she has become the holder of such Shares. Notwithstanding the foregoing, in connection with each grant of Restricted Stock hereunder, the applicable Award Agreement shall specify if and to what extent the Participant shall be entitled to the rights of a stockholder in respect of such Restricted Stock.

(j) Governing Law. The validity, construction, and effect of the Plan and any rules and regulations relating to the Plan and any Award Agreement shall be determined in accordance with the laws of the State of Delaware, applied without giving effect to its conflict of laws principles.

(k) Severability. If any provision of the Plan or any Award is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any Person or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to the applicable laws, or if it cannot be construed or deemed amended without, in the

A-13

determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be stricken as to such jurisdiction, Person or Award and the remainder of the Plan and any such Award shall remain in full force and effect.

(l) Other Laws. The Committee may refuse to issue or transfer any Shares or other consideration under an Award if, acting in its sole discretion, it determines that the issuance or transfer of such Shares or such other consideration might violate any applicable law or regulation or entitle the Company to recover the same under Section 16(b) of the Exchange Act, and any payment tendered to the Company by a Participant, other holder or beneficiary in connection with the exercise of such Award shall be promptly refunded to the relevant Participant, holder or beneficiary. Without limiting the generality of the foregoing, no Award granted hereunder shall be construed as an offer to sell securities of the Company, and no such offer shall be outstanding, unless and until the Committee in its sole discretion has determined that any such offer, if made, would be in compliance with the requirements of all applicable securities laws.

(m) No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any Affiliate and a Participant or any other Person. To the extent that any Person acquires a right to receive payments from the Company or any Affiliate pursuant to an Award, such right shall be no greater than the right of any unsecured general creditor of the Company or such Affiliate.

(n) No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to the Plan or any Award, and the Committee shall determine whether cash, other securities, or other property shall be paid or transferred in lieu of any fractional Shares or whether such fractional Shares or any rights thereto shall be canceled, terminated, or otherwise eliminated without additional consideration.

(o) Deferrals. In the event the Committee permits a Participant to defer the payment or settlement in Shares of all or any portion of an Award, all such elective deferrals shall be accomplished by the delivery of a written, irrevocable election by the Participant on a form provided by the Company. All deferrals shall be made in accordance with administrative guidelines established by the Committee to ensure that such deferrals comply with all applicable requirements of Section 409A of the Code.

(p) Headings. Headings are given to the Sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision thereof.

Section 16. Compliance with Section 409A of the Code.

(a) To the extent applicable, it is intended that the Plan and any Awards granted hereunder comply with, or be exempt from, the provisions of Section 409A of the Code, so that the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to the Participants. The Plan and any Awards granted hereunder shall be administered in a manner consistent with this intent. Any reference in the Plan to Section 409A of the Code will also include any regulations or any other formal guidance promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service.

(b) Neither a Participant nor any of a Participant’s creditors or beneficiaries shall have the right to subject any deferred compensation (within the meaning of Section 409A of Code) payable under the Plan and Awards granted hereunder to any anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishment. Except as permitted under Section 409A of the Code, any deferred compensation (within the meaning of Section 409A of the Code) payable to a Participant or for a Participant’s benefit under the Plan and Awards granted hereunder may not be reduced by, or offset against, any amount owing by a Participant to the Company or any of its Affiliates.

(c) If, at the time of a Participant’s separation from service (within the meaning of Section 409A of the Code), (i) the Participant shall be a specified employee (within the meaning of Section 409A of the Code and

A-14

using the identification methodology selected by the Company from time to time) and (ii) the Company shall make a good faith determination that an amount payable hereunder constitutes deferred compensation (within the meaning of Section 409A of the Code) the payment of which is required to be delayed pursuant to the six-month delay rule set forth in Section 409A of the Code in order to avoid taxes or penalties under Section 409A of the Code, then the Company shall not pay such amount on the otherwise scheduled payment date but shall instead pay it on the earlier of (A) the first business day of the seventh month following the Participant’s separation from service or (B) the date of the Participant’s death.

(d) Notwithstanding anything to the contrary in the Plan or any Award Agreement, to the extent that the Plan and/or Awards granted hereunder are subject to Section 409A of the Code, the Committee may, in its sole discretion and without a Participant’s prior consent, amend the Plan and/or Award, adopt policies and procedures, or take any other actions (including, without limitation, amendments, policies, procedures and actions with retroactive effect) as the Committee determines are necessary or appropriate to (i) exempt the Plan and/or any Award from the application of Section 409A of the Code, (ii) preserve the intended tax treatment of any such Award, or (iii) comply with the requirements of Section 409A of the Code, including, without limitation, any regulations or other guidance that may be issued after the date of the grant. In any case, notwithstanding anything to the contrary, a Participant shall be solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on a Participant or for a Participant’s account in connection with the Plan and Awards granted hereunder (including, but not limited to, any taxes and penalties under Section 409A of the Code), and neither the Company nor any of its Affiliates shall have any obligation to indemnify or otherwise hold a Participant harmless from any or all of such taxes or penalties.

Section 17. Term of the Plan.

(a) Effective Date. The Plan was approved by the Board on April 20, 2022. The Plan shall be effective as of the date of its approval by the stockholders of the Company (such date, the “Effective Date”). If the Plan is approved by stockholders on the Effective Date, no future awards will be made under the 2020 Plan.

(b) Expiration Date. No Award will be granted under the Plan more than ten years after the Effective Date, but all Awards granted on or prior to such date will continue in effect thereafter subject to the terms thereof and of the Plan.
