About the cover art : Our stakeholders often ask us what the “crystal ball” is telling us about the future of our markets, offerings, and performance. With this in mind, our talented graphic designers imagined an Oceaneer gazing into an aquatic sphere where future offerings are springing forth to join our core current business lines. The Oceaneer is demonstrating our mission to “Solve the Unsolvable” as a new day dawns.

Message from our

Chief Executive Officer

To our stockholders,

Oceaneering’s story has always been

about inspiration and innovation —

inspiration that comes from facing a

challenge that seems insurmountable, and

innovation that comes from working

together to achieve outcomes more

meaningful than any one of us could have

accomplished on our own.

Our unique culture and values enable us to apply advanced technologies and

integrated solutions to solve complex problems in harsh environments. In a

complex, globally interconnected, and increasingly digitally driven world, it’s our

common identity as Oceaneers that enables us to carry out our mission to “solve

the unsolvable.”

In 2024, our focus remained on building confidence and credibility with all of our

stakeholders, and I am pleased to share that we continue to deepen our

relationship with existing customers, improve talent retention and safety, and

deliver strong financial performance for our stockholders. You can learn more

about our financial and other business highlights throughout this proxy statement.

We look forward to working with all of our stakeholders to define what’s possible

for our shared future as we continue developing the remote, resident, and

autonomous technology solutions that are needed to achieve the best planet, for

the most people, for the longest time. On behalf of our Board of Directors, our

leadership team, and all Oceaneers around the globe, I want to thank you for

your investment and continued support.

Regards,

Roderick A. Larson President and Chief Executive Officer

Role of the Board of Directors

Oversight of Company Strategy and Risk

Our Board, with the assistance of its committees and our executive management team, oversees the

development and implementation of our long-term business strategy as well as the identification and

management of key risks and opportunities. To this end, our Board applies an external perspective and a

deep understanding of our business and global footprint, engages in continuous dialogue with

management, and adheres to a governance framework set forth in our Corporate Governance Guidelines

and respective committee charters, each of which is available under the Governance tab in the Investors

section of our website (www.oceaneering.com) .

Given our Board members’ deep experience and expertise in our industry and the industries of our

customers, technology and cybersecurity, human capital management, corporate development, and

governance, they are well positioned to engage in constructive discussions with management to inform

decisions regarding our budget and capital plans, business initiatives, and our long-term business

strategy to promote the best interests of our stockholders.

In reviewing the Company’s compensation program, the Compensation Committee has determined that

our compensation policies and practices do not create risks that are reasonably likely to have a material

adverse effect on the Company.

Our Board dedicates significant time at each Board meeting and at annual on-site strategic planning

sessions to the oversight of strategy and risks, including the following :

Strategy Oversight	Risk Oversight
With an enterprise-level perspective, encouraging investment and strategic divestment to maximize stockholder returns	Ensuring compensation programs do not encourage excessive risk-taking
Ensuring compensation philosophy and programs are aligned to strategic objectives	Encouraging sufficient investment in cybersecurity and business enablement
Assessing potential impact of evolving regulatory geopolitical landscape on business strategy	Monitoring management’s awareness and mitigation strategies for risks associated with generative AI and other emerging technologies
Preparing for potential business model disruption by rapid technological advancement	Verifying sufficient controls to promote accurate and timely financial reporting, regulatory compliance, and prevention of conflicts of interest and other lapses in ethical business practices
Challenging existing and future markets and market penetration	Promoting a culture that appreciates and prioritizes protection of health, safety, security, and environment
Ensuring sufficient focus on workforce of the future	Monitoring geopolitical changes for potential financial impact and encouraging robust regulatory compliance programs

Our Corporate Governance Framework

Oceaneering’s Board operates according to its Corporate Governance Principles and committee charters,

each of which is available under the Governance tab in the Investors section of our website

(www.oceaneering.com) , which promote effective decision-making and robust oversight within a flexible

structure that accounts for changing circumstances and the needs of our dynamic business. Summarized

below are several key attributes of our governance framework .

Access to management	Board members have access to management routinely and by outreach.
Annual self- evaluations	The Board engages in annual self-, peer-, and Board assessments to identify areas that can be developed through training, education, and board succession planning.
Committee Members are Independent	Committee members are independent and were never employed by the Company.

Board Independence

Under rules adopted by the NYSE, our Board must have a majority of independent directors. The director

independence standards of the NYSE require a board determination that a director have no material

relationship with us and no specific relationships that preclude independence. Our Board considers

relevant facts and circumstances in assessing whether a director is independent. Our Board has

determined that, with the exception of Mr. Larson , our President and Chief Executive Officer, all of our

directors currently meet the NYSE independence requirements.

Business Resiliency

At Oceaneering, we take a measured and data-driven approach to our work as we endeavor to “Solve the

Unsolvable” for our customers. As public discourse and geopolitical perspectives diverge on whether and

to what extent for-profit companies should prioritize environmental, social, and governance (“ESG”)

matters, our perspective has not changed. We have always prioritized business resiliency over short-term

accolades. Aligned with our Core Values, we carefully consider the complex interdependencies of

stockholder sentiment, customer demand, legal and regulatory landscape, geopolitical shifts,

technological developments, and the principles of our global workforce, all against the backdrop of our

commitment to deliver superior stockholder returns.

We continue to attract, retain, develop, motivate, and equip the most talented, qualified, and effective

global workforce, management team, and Board. We continue to promote effective ethics and compliance

programs. We continue to diversify our business in energy and non-energy markets, and we continue to

advance our greenhouse gas reduction initiatives. (1)

Today, we generate the majority of our revenue from the oil and gas sector, so we carefully and

continually study the impact and timing of energy transition on our business. Our outlook, and pace of

increasing industry diversification, depends largely on the ongoing demand for oil and natural gas

products and services. We consider and rely on information from customers, third-party advisors, and

other sources as well as our own views on the principal drivers of demand for oil and gas.

Due to the continuing growth of populations and economies in developing countries; the increasing

demand for energy to support data centers and other emerging technological needs; the shortage of

other sources of affordable, reliable, scalable, and efficient energy; and rising worldwide demand for a

myriad of products made with petrochemicals, we expect that the need for additional oil and gas

exploration and development will continue for decades to come.

At the same time, due to concerns about climate change, we monitor and respond to demand for and

investment in cleaner hydrocarbon-based and renewable energy sources. We strive to meet the growing

need for lower-carbon energy by assisting customers to reduce their carbon emissions in exploring for,

developing, and producing oil and natural gas, while also diversifying our business into new strategic

growth areas in emerging energy and non-energy markets.

(1) Our assessment of the current and future demand for oil and gas is continually evolving and includes

consideration of many factors as further described in our Task Force on Climate Related Financial

Disclosures (“TCFD”) report. We voluntarily disclose our greenhouse gas reduction initiatives, including our

key ESG metrics, consistent with the Sustainability Accounting Standards Board (“SASB”) voluntary

disclosure framework. Our TCFD and SASB reports can be found the Sustainability tab under the About Us

section of our website at: www.oceaneering.com. Unless specifically stated herein, documents and

information on our website are not incorporated by reference into this proxy statement.

Other Corporate Governance Information

Board Meetings and Attendance

During 2024 , our Board held six meetings of the full Board and 15 meetings of committees of the Board.

Each of our directors attended at least 75% of the aggregate number of meetings of the Board and

meetings of committees of the Board on which they served (during the period of service). All directors are

invited to attend meetings of all committees of the Board, and in 2024, no committee meetings were

scheduled or held concurrently; as a result, most directors attended most or all of the committee

meetings regardless of whether they served on the committees.

In addition, directors are encouraged to attend the Annual Meeting. Last year, all of our directors attended

our Annual Meeting. In 2024 , the nonemployee directors met in regularly scheduled executive sessions

without management present, and similar sessions are scheduled for 2025 . The chairs of the Board, Audit

Committee, Compensation Committee and Nominating, Corporate Governance & Sustainability

Committee chair these executive sessions under our Corporate Governance Guidelines.

Compensation Committee Interlocks and Insider Participation

No member of the Compensation Committee has served as one of our officers or employees at any time.

None of our executive officers serves as a member of the compensation committee of any other company

that has an executive officer serving as a member of our Board. None of our executive officers serves as

a member of the board of directors of any other company that has an executive officer serving as a

member of our Compensation Committee. None of our directors or executive officers are members of the

same family.

Related Party Policy and Transactions

The Board has adopted a written policy for approval of transactions between the Company and its

directors, director nominees, executive officers, greater than 5% beneficial owners of our common stock,

and each of their respective immediate family members, where the amount involved in the transaction

exceeds or is reasonably expected to exceed $120,000 in a single fiscal year and the related party has or

will have a direct or indirect interest in the transaction. Certain transactions are pre-approved or excluded

from consideration. A copy of this policy is available under the Governance tab in the Investors section of

our website (www.oceaneering.com) .

In the event of any transaction subject to the policy, consideration may be given to:

• The nature and extent of the related person’s interest and involvement in the transaction;

• The approximate dollar value involved in the transaction;

• Whether the transaction was undertaken in the ordinary course of Oceaneering’s business;

• Any material terms of the transaction, including whether the transaction is or would be on terms no

less favorable to Oceaneering than terms that could have been reached with an unrelated party;

• The business purpose of, and the potential benefits to Oceaneering of, the transaction;

• Whether the transaction would impair the independence of a non-employee director;

• Required public disclosure, if any; and

• Any other information regarding the transaction or the related person.

Several of our Board members and executive officers serve as directors or executive officers of other

organizations, including organizations with which we have or may have commercial and charitable

relationships. We do not believe that any director or nominee had a direct or indirect material interest in

any covered transactions during 2024 and through the date of this Proxy Statement.

Stephen Lazar, Jr. , who is a brother-in-law of Mr. McEvoy , serves as Director, Sustainability , for which Mr.

Lazar received total compensation for 2024 of approximately $251,000 . Mr. Lazar ’s compensation was

established by the Company in accordance with our compensation practices applicable to employees

Table of Contents

with comparable qualifications and responsibilities and holding similar positions and is commensurate

with that of his peers in our compensation framework.

Business Conduct Policy

Our Board adopted a code of ethics that applies to our Chief Executive Officer and senior financial

officers, including our Chief Financial Officer, Chief Accounting Officer, and Treasurer or Controller, and a

code of business conduct and ethics that applies to all our directors, officers, and employees. Each is

available under the Governance tab in the Investors section of our website (www.oceaneering.com) . Any

stockholder may obtain a printed copy of these codes from us upon request. Any change in or waiver of

these codes of ethics will be disclosed on our website.

Board Composition and Succession Planning

Our Board believes that effective oversight and advancement of our long-term strategy comes from the

contributions of directors with diverse and complementary qualifications, attributes, skills, and expertise

(“Qualifications”) aligned to our long-term strategy and Core Values. The Nom inating, Corporate

Governance & Sustainability Committee regularly reviews these Qualifications, a subset of which is

summarized on the Board Skills and Experience Matrix below.

The Board endeavors to retain directors with a deep knowledge of Oceaneering and its relevant

industries as well as to attract directors with fresh perspectives. The Nominating, Corporate Governance

& Sustainability Committee intentionally conducts broad searches with the assistance of outside advisors

to maintain a wide pool of potential board members.

Board Qualifications

In assessing the qualifications of existing and prospective nominees to the Board, the Nominating,

Corporate Governance & Sustainability Committee considers, i n addition to criteria in our Amended and

Restated Bylaws (the “Bylaws”) and Corporate Governance Guidelines, each nominee’s integrity,

experience, skills, ability and willingness to devote the time and effort necessary to be an effective board

member, and commitment to acting in the best interests of Oceaneering and its stockholders. The Board

believes that its current composition reflects a group of highly talented individuals with the Qualifications

and perspectives best suited to perform oversight responsibilities for Oceaneering and our stockholders

and to promote achievement of our long-term strategy.

In selecting and defining the Qualifications reflected in the Board Skills and Experience Matrix below, the

Board considered how such Qualifications align to its oversight capabilities, critical needs, and strategic

priorities. The Board recognizes that its members have at least a deep proficiency in all or nearly all of the

identified Qualifications. However, based on a contextual review of the particular roles each director plays

on the Board, it selected a Qualification for a director only if it was gained through experience as a senior

executive with significant responsibility over time or with high-profile complex matters. The absence of a

selection on the Board Skills and Experience Matrix should not be interpreted as a lack of expertise or

contribution as it relates to that skill. The Company benefits greatly from having directors with diverse skill

sets who contribute in ways that go beyond the items highlighted on the matrix.

In addition to the Qualifications highlighted on the Board Skill and Experience Matrix below:

• All members of our Board have been determined to be financially literate.

• Other than Mr. Larson , all members of our Board have been determined to be independent

according to the standards of the New York Stock Exchange. In addition, our standing Board

committees are entirely comprised of independent Board members who were not previously

employed by Oceaneering.

• All members of our Board have held executive and board roles with publicly traded companies

where they have had significant responsibility driving and overseeing organic and inorganic growth

and expansion, strategic plan development, and driving stockholder value.

• Our Board members’ service ranges from one to 14 years, with an average tenure of eight years.

installments, of $105,000 for the Chair and $70,000 for each of our other nonemployee directors. For

2024 , the Board also approved additional annual cash retainers, payable in quarterly installments, of (i)

$30,000 to the chair and $10,000 to each member of the Audit Committee, (ii) $20,000 to the chair and

$10,000 to each member of the Compensation Committee and (iii) $10,000 to the chair and $5,000 to

each member of the Nominating, Corporate Governance & Sustainability Committee. Mr. Larson , our

Chief Executive Officer, does not receive separate compensation for his service as a director. See the

“Summary Compensation Table” above for information concerning the compensation paid to Mr. Larson .

During 2024 , besides payment of annual retainers, our nonemployee directors were also allowed to

participate in health care coverage on the same basis as provided to employees in our basic medical

plans. Nonemployee directors could elect to participate in the health care plan without payment of any

monthly premium and participate in a supplemental medical plan at no cost to the director. All directors

are provided a group personal excess liability insurance policy at no cost to the directors. Directors are

reimbursed for their travel and other expenses involved in attendance at Board and committee meetings

and activities. The Compensation Committee and Board voted to discontinue all insurance benefits for

the directors after 2024.

In 2024 , our nonemployee directors were awarded shares of restricted stock under our Incentive Plan (as

defined below) as follows: Mr. McEvoy : 12,982 shares; and each of our other nonemployee directors:

8,743 shares. The awards were subject to (1) possible earlier vesting on a change of control or the

termination of the director’s service due to death, and (2) such other terms as were set forth in the award

agreements with the respective directors. For information about stock ownership guidelines for

nonemployee directors, see “ Compensation Discussion & Analysis — Stock Ownership Guidelines.”

computed in accordance with FASB ASC Topic 718. For a discussion of valuation assumptions, see Note 12 to our consolidated

financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2024. The aggregate number of

restricted shares outstanding as of December 31, 2024, was 12,982 for Mr. McEvoy and 8,743 for each of our other nonemployee

directors.

(3) For each director, the amount shown for 2024 reflects premiums for medical insurance, including supplemental medical insurance and,

for each of Mses . Goodwin and Poddar and Messrs. McEvoy , Murphy and Reinhardsen, basic medical insurance. Our nonemployee

directors had excess liability insurance coverage from January 1, 2024 until December 1, 2024, the premiums of which were paid in

2023 and therefore reported in our Definitive Proxy Statement on Schedule 14A with respect to our 2024 annual meeting of

stockholders.

Message from the Compensation Committee

Dear fellow stockholders ,

On behalf of our Board, we would like to thank you for your continued investment in Oceaneering. Every

day, talented Oceaneers work toward a mission to “Solve the Unsolvable,” and year after year, they have

risen to the challenge. We believe that this winning culture results from exceptional leadership, starting

with that of our CEO, Rod Larson. We also believe that the work of our Compensation Committee

maintains alignment among our leaders, our workforce, and our stockholders.

The Compensation Committee’s work oversees the development of the competitive compensation

program and its alignment with the interests of our stockholders. We review CEO and executive

performance against short- and long-term metrics aligned with our business strategy. We also review our

employee engagement survey data to ensure Oceaneering’s winning culture continues to mature in a

rapidly changing world.

We believe our compensation programs are working as intended to ensure high performance while

reducing the likelihood that management takes unreasonable risks. In 2024 compared to the prior year,

all five operating segments improved revenue, consolidated revenue increased 10% to $2.7 billion ,

consolidated operating income improved by 36% to $246 million , net income improved by 51% to $147

million , consolidated adjusted EBITDA (non-GAAP) increased by 20% to $347 million , we grew the

company by organic and inorganic capital investment, we returned value to stockholders through our

stock repurchase program, and we ended the year with healthy liquidity. More information regarding our

performance in 2024 can be found under “ Compensation Discussion & Analysis ” below.

This year’s employee engagement survey results were also positive, with Oceaneers resoundingly

expressing their individual alignment to company success: 94% agreed with the statement “I understand

how my role contributes to Oceaneering’s success.” We were pleased to see Oceaneers reporting high

levels of satisfaction and signs of strength of our culture .

Finally, we appreciate the high level of support you have given to our executive compensation. In the past

two years, you supported our executive compensation at a level of 93% and 94% , respectively . This year,

we have streamlined our compensation-related disclosures to explain our compensation philosophies and

the results of our compensation programs. We ask that you vote FOR our proposals related to executive

compensation and the approval of an amended and restated 2020 Incentive Plan , and we th ank you for

your continued support.

Compensation Discussion & Analysis

The following Compensation Discussion and Analysis, or “CD&A , ” provides information regarding the

compensation programs in place for our Chief Executive Officer, Chief Financial Officer, and three other

most highly compensated executive officers during 2024 . We refer to these individuals in this Proxy

Statement as the “Named Executive Officers.”

Named Executive Officers
Name	Title as of January 1, 2024
Roderick A. Larson	President and Chief Executive Officer
Alan R. Curtis	Senior Vice President and Chief Financial Officer
Martin J. McDonald	Senior Vice President, Subsea Robotics
Earl F. Childress	Senior Vice President and Chief Commercial Officer
Benjamin M. Laura	Senior Vice President and Chief Innovation Officer (1)

(1) Mr. Laura was promoted to, and now serves as, Senior Vice President and Chief Operating Officer, effective

January 1, 2025.

This CD&A also includes information regarding, among other things, the objectives of our compensation

program, the achievements that the compensation program is designed to reward, the elements of the

compensation program (including the reasons why we employ each element and how we determine

amounts paid) and how each element fits into our overall compensation objectives. As used in this CD&A,

references to the “Committee” mean the Compensation Committee of our Board .

Compensation Philosophy and Objectives

Our executive compensation program is designed to attract and retain key executives, motivate them to

achieve our s hort- and long-term objectives without exposing us to excessive or unnecessary risk, and

align their interests with our stockholders’ interests. To achieve these goals, we’ve designed our

executive compensation program to deliver a competitive compensation package and to reward our key

executives for superior performance, and our executive compensation program utilizes several different

compensation elements that are geared towards both our short-term and long-term performance. The

following principles influence the design and administration of our executive compensation program, and

we believe that its key elements described below are aligned with best practices and sound policy,

including:

Our compensation programs are tied to performance and motivate our key executives	• Performance measured against financial and other key performance objectives. • Balances long-term and short-term performance to promote stockholder value. • Incentive compensation forms a significant part of key executives’ total direct compensation, with more than 50% of CEO’s total direct compensation at risk.
Our compensation programs encourage our leaders to make decisions aligned with stockholder value.	• 86 % of CEO’s total direct compensation is at risk and tied to our delivery of short- and long-term stockholder value. • Our executives are subject to stock ownership guidelines, requiring them to own shares of our common stock having a market value or cost basis not less than a multiple of their base salary. The minimum holding requirement for our CEO is five times his base salary.
Our compensation programs are designed to attract and retain the best leaders.	• Our compensation programs are competitive and benchmarked against industry market data and information from our compensation peer group. • Long-term incentives help us retain key executives, who have a keen understanding of our services and products in the markets we serve, and who maintain strong customer relationships over time. • Our compensation programs fairly reward performance and service across volatile market cycles.

For more information, please see our Compensation and Governance Best Practices Table under “ — Our

Corporate Governance Framework ” above.

Table of Contents

We believe that our compensation philosophy motivates our executives to pursue objectives that benefit

our stockholders. O ur continued focus in 2024 on growth and delivering on our strategic plan has enabled

us to:

• achieve our second-best Total Recordable Incident Rate (TRIR) by maintaining a strong emphasis

on health and safety, particularly on life-saving rules, high-hazard tasks and engineered solutions;

• improve Adjusted EBITDA and continue our year-over-year growth ;

• generate positive Free Cash Flow in 2024 and maintain strong liquidity while executing on

approximately $20 million of share repurchases to return value to our stockholders;

• generate positive TSR (as defined below under “— Executive Compensation Components — Long-

Term Incentive Compensation — 2022-2024 Performance Units”) of 142% over a three-year time

period; and

• advance our innovative robotics, automation and remote-operations solutions to enhance safety

and efficiency, including completing the acquisition of Global Design Innovation Ltd. (GDi), a digital

twin and software services provider.

The Role of the Compensation Committee

The Committee has the primary authority to establish compensation for our executive officers (including

the Named Executive Officers) and other key employees and administers all our executive compensation

programs and agreements. The Committee annually reviews and approves corporate goals and

objectives and sets the compensation levels for our executive officers based on the Committee’s

evaluation. Our Chief Executive Officer assists the Committee by providing annual recommendations

regarding the compensation of our executive officers and other key employees, excluding himself. The

Committee can exercise its discretion in modifying or accepting these recommendations. The Chief

Executive Officer, Chief Human Resources Officer, and Chief Legal Officer attend Committee meetings.

However, the Committee also meets in executive session without members of management present.

The Committee reviews comparative compensation information compiled by a compensation consultant

as described in “— The Role of the Compensation Consultant ” below. Comparative compensation

information, however, is only one factor used by the Committee in making its compensation decisions,

and the Committee does not base its decisions on targeting any compensation to specific pre-determined

benchmarks. Overall, our compensation program for the Named Executive Officers is intended to create

a total compensation opportunity that, on average, is competitive with the median of a peer group and

survey data identified by the Compensation Consultant, as discussed in “— Compensation

Benchmarking ” below. For additional information regarding the role and responsibility of the Committee,

please see “Committees of the Board — Compensation Committee ” above.

Impact of 2024 Say-on-Pay Vote on Executive Compensation

In approving the 2025 compensation of the Named Executive Officers, the Committee reviewed the vote

on the say-on-pay proposal at the 2024 Annual Meeting of Stockholders. Approximately 94% of the votes

cast on the say-on-pay proposal at that meeting were voted in favor of the proposal. The Committee

believes this affirms stockholders ’ support of Oceaneering’s approach to executive compensation.

Accordingly, the Committee did not adopt any specific changes based on the vote.

The Committee will continue to consider the outcome of Oceaneering’s say-on-pay votes when making

future compensation decisions for named executive officers. The Committee expects to continue to hold

say-on-pay votes every year, which is consistent with the votes cast by stockholders at the 2023 Annual

Meeting regarding the frequency of such votes.

Management regularly engages in discussions with stockholders on a variety of topics, including

executive compensation. In general, during these discussions, stockholders expressed their overall

support of our approach to compensation and our performance-oriented program design.

The Role of the Compensation Consultant

The Committee has the authority to engage a compensation consultant, outside legal counsel, and other

advisors, in its sole discretion, to assist the Committee in the discharge of its duties and responsibilities.

As noted in “Committees of the Board — Compensation Committee” above, for the current compensation

cycle, the Committee continued to retain Meridian as the Compensation Consultant to:

• review the peer group of companies used for comparison purposes in the preceding year and

assess the peer group’s continued validity;

• conduct a review of the competitiveness of our total direct compensation, retirement benefits and

perquisites of the Named Executive Officers and other key employees, relative to data disclosed in

proxy statements and other filings with the SEC by the peer group of companies and survey data;

• conduct a pay-for-performance analysis to assess the alignment of amounts realized from our

executive compensation program and performance for Oceaneering and the peer group of

companies identified;

• assess Oceaneering’s incentive structure for executive officers and the alignment of that structure

with Oceaneering’s compensation philosophy and objectives;

• assess Oceaneering’s compensation for nonemployee directors relative to market practices,

including the compensation programs of a peer group of companies; and

• assist the Committee in its duties with respect to the compensation of our executives, nonemployee

directors and other key employees.

The Committee has engaged Meridian since 2015 to provide similar assistance to the Committee with

respect to the compensation of our executive officers and nonemployee directors. The decision to engage

the Compensation Consultant and approval of its compensation and other terms of engagement were

made by the Committee without reliance on any recommendation of management. The Compensation

Consultant’s only work for Oceaneering for the current compensation cycle, as in prior cycles, was at the

direction of the Committee. The Committee considered this and other factors in its recent assessment of

the independence of the Compensation Consultant and concluded that the Compensation Consultant’s

work for the Committee does not raise any conflict of interest issues.

To assist the Committee in setting compensation of the Named Executive Officers for 2024 , the

Compensation Consultant assessed the competitiveness of Oceaneering’s executive compensation

program relative to industry benchmarks, and the alignment of that program with Oceaneering’s

compensation philosophy and objectives, and advised that:

• certain changes to the peer group were recommended for consideration by the Committee in setting

the compensation of the Named Executive Officers (see “— Compensation Peer Group ” below);

• our mix of salary, bonus and long-term incentives for Named Executive Officers aligns closely with

our peers; and

• amounts realized from our executive compensation program were generally aligned with

Oceaneering’s performance.

Compensation Peer Group

The Compensation Consultant assessed the peer group of companies (the “Compensation Peer Group”)

used for comparison purposes in the prior year’s review to recommend any changes for purposes of

determining the 2024 compensation of the Named Executive Officers and replaced Exterran Corporation,

which was acquired, with Noble Corporation.

The companies included in the Compensation Peer Group were approved for inclusion by the Committee

primarily due to: their operational focus in broadly comparable industries, notably the oilfield services

industry; their comparable size (typically 0.3 to 3.0 times Oceaneering’s annual revenue and enterprise

value); and the belief that we compete with many of these companies for talent and for stockholder

investment.

Table of Contents

The table below sets forth the companies (besides Oceaneering) comprising the Compensation Peer

Group, for purposes of determining the 2024 compensation of the Named Executive Officers.

ChampionX Corporation	Flowserve Corporation	DNOW, Inc.
Chart Industries, Inc.	Helix Energy Solutions Group, Inc.	Oil States International, Inc.
Dril-Quip, Inc.	Helmerich & Payne, Inc.	Transocean Ltd.
Expro Group Holdings N.V.	Noble Corporation	Weatherford International plc

As of October 2023, when the analysis was completed, Oceaneering was positioned slightly below the

median of the Compensation Peer Group in terms of revenue and between the 25th percentile and the

median of the Compensation Peer Group in terms of enterprise value.

As in prior years, the Compensation Consultant also analyzed survey data beyond the Compensation

Peer Group for the Committee’s consideration. For 2024, the survey data was obtained from the Equilar

Top 25 Survey (the “Compensation Survey Data”), representing a custom group of energy-related and

manufacturing companies of comparable size in terms of revenue and enterprise value. As of October

2023 when the analysis of the Compensation Survey Data was completed, Oceaneering was positioned

near the median in terms of revenue and between the 25th percentile and median in terms of enterprise

value.

Compensation Benchmarking

The Compensation Consultant conducted a market analysis of Oceaneering’s executive compensation

levels and the components of such compensation relative to the Compensation Survey Data and

Compensation Peer Group disclosure data (as discussed in “— The Role of the Compensation

Consultant ” above). In its analysis, the Compensation Consultant identified the 25th, 50th and 75th

percentiles for each of our executive officers based on position and pay rank, considering base salary

and target values for annual bonus and long-term incentive compensation, individually and in the

aggregate. The Compensation Consultant identified these percentiles from (1) information disclosed in

relevant filings with the SEC by the companies comprising the Compensation Peer Group and (2) the

Compensation Survey Data. The Compensation Consultant provided this and other information to the

Committee at the Committee’s regularly scheduled meetings in the fourth quarter of 2023 and first quarter

of 2024 to assist with the establishment of 2024 compensation. The Committee considers the

Compensation Consultant’s analysis as part of the Committee’s process in seeking to establish and

maintain target total compensation that is competitive.

Pay for Performance

As described further in “— Executive Compensation Components” under the headings “ Annual Incentive

Awards Paid in Cash ” and “ Long-Term Incentive Compensation ” below, a significant portion of the total

direct compensation of our Named Executive Officers is delivered through variable compensation

elements that are tied to financial performance goals in our annual cash bonus and long-term

performance unit programs, as well as stockholder return and safety objectives.

Table of Contents

Executive Compensation Components

For 2024 , the primary components of our compensation program for Named Executive Officers were: — ●	●	●
Annual base salary	Annual incentive awards paid in cash	Long-term incentive awards (comprised of restricted stock units and performance units)
Our Named Executive Officers also receive certain retirement benefits, which comprised a relatively small percentage of compensation, as further described under “— Post-Employment Compensation Programs — Retirement Plans ” below.

The Compensation Consultant found that the mix of direct compensation components (base salary and

annual and long-term incentive awards at target) for the Named Executive Officers was aligned with

compensation peer group practices, with long-term incentives comprising on average at least half of the

executives’ target total direct compensation. For 2024 , the target total direct compensation of the Named

Executive Officers that was at risk and tied to our delivery of short- and long-term stockholder value was

86% for Mr. Larson, our Chief Executive Officer, and between 66% and 79% for each of the other Named

Executive Officers. These components for our CEO and peer company CEOs are shown below.

Oceaneering CEO Peer Company CEOs

Annual Base Salary

The Committee considers base salary levels on an annual basis as well as upon a promotion or

significant change in job responsibility. Each year, our Chief Executive Officer recommends base salaries

for the other executive officers based on market dynamics as well as individual and operational or

functional group contributions and performance over the past year. In reviewing the Chief Executive

Officer’s recommendations and in deciding base salaries for all executive officers, the Committee

considers each officer’s level of responsibility, experience, tenure, performance, and the comparative

compensation information provided by the Compensation Consultant. The Committee’s evaluation of

each executive officer also takes into account an evaluation of Oceaneering’s overall performance. In

Table of Contents

light of the above considerations, in February 2024 , the Committee approved salary increases, effective

January 1, 2024 , as follows:

Name	2023 Base Salary	2024 Base Salary	Percentage Increase
Roderick A. Larson	$800,000	$840,000	5%
Alan R. Curtis	$452,620	$466,199	3%
Martin J. McDonald	$371,315	$386,168	4%
Earl F. Childress	$378,525	$389,881	3%
Benjamin M. Laura	$375,950	$394,748	5%

Annual Incentive Awards Paid in Cash

In late February or early March of each year, the Committee approves a performance-based annual cash

bonus award program (the “Annual Cash Bonus Program”) under our stockholder-approved incentive

plan for executive officers and certain other employees (our “Incentive Plan”). Around that time, the

Committee also approves the final bonus amounts payable under the Annual Cash Bonus Program for

the immediately preceding year.

In February 2024 , the Committee approved the Annual Cash Bonus Program for 2024 . For each Named

Executive Officer, the bonus opportunity was measured by 2024 Adjusted EBITDA , 2024 Free Cash Flow ,

and safety and environmental goals for calendar year 2024 , as follows:

Performance Measures	Weight	Definition
Adjusted EBITDA	60%	Consolidated net income (loss) before interest, taxes, depreciation and amortization for the year, adjusted to remove the net impact of the following for such year: foreign currency gains and losses; sales of fixed assets and investments resulting in gains or losses; impairments of long-lived assets; write- downs or write-offs of assets; corporate restructuring expenses; and other unusual items; in each case, as may be approved by the Committee (“ 2024 Adjusted EBITDA ”). In 2024, we took an adjustment for foreign exchange gains and loss on the sale of an asset.
Free Cash Flow	25%	Net cash provided by Oceaneering’s operating activities less purchases of property and equipment for such year (e.g., organic capital expenditures, which exclude those incurred in business acquisitions) (“ 2024 Free Cash Flow ”).
Safety	10%	Verification of safety-critical controls, the elimination of hazards through engineered improvements and the implementation of safety-related corrective actions and process improvements.
Environmental	5%	Activities focused on ensuring environmental resiliency of our operations.

The cash payout opportunity under the program for each Named Executive Officer was a specified

percentage of their 2024 base salary, adjusted for the attainment of program goals as described below.

As recommended by our Chief Executive Officer and approved by the Committee in February 2024 , the

plan amount for our 2024 Adjusted EBITDA was $355 million and for our 2024 Free Cash Flow was $130

million , which reflected our forecast assumptions of expected demand and stable-to-improving pricing for

our services and products, the timing of cash payments related to certain projects and the achievement of

operational and cost improvements in 2024 . The target bonus opportunity was payable upon

achievement of our plan amount.

Table of Contents

The executive officers in the Annual Cash Bonus Program for 2024 and their respective target awards,

each as a percentage of base salary, included:

Name	Target Bonus Award (as a Percentage of Base Salary)
Roderick A. Larson	125%
Alan R. Curtis	80%
Martin J. McDonald	70%
Earl F. Childress	70%
Benjamin M. Laura	75%

In 2024 , the Annual Cash Bonus Program participation levels for our Named Executive Officers, in each

case as a percentage of base salary, were unchanged from 2023 (except for Mr. Childress , whose

participation level increased from 65% to 70% effective January 1, 2024 ) and were consistent with the

levels approved for our Named Executive Officers in previous years.

The table below notes the percentages of the Adjusted EBITDA and Free Cash Flow components of a

Named Executive Officer’s target award payable under the Annual Cash Bonus Program for the

percentages of target 2024 Adjusted EBITDA and 2024 Free Cash Flow achieved, with interpolation

between the performance levels shown. The Committee has the discretion to award an amount other

than that calculated but did not exercise such discretion this year.

Performance Level	2024 Adjusted EBITDA ($)	2024 Free Cash Flow ($)	% of 2024 Adjusted EBITDA Target	% of 2024 Free Cash Flow Target	% of Target Payout
Gate	$231,000,000	—	65%	—%	—%
Threshold	$248,000,000	$70,000,000	70%	54%	25%
Target (Plan)	$355,000,000	$130,000,000	100%	100%	100%
Maximum	$411,000,000	$200,000,000	116%	154%	200%

In addition, assuming attainment of 2024 Adjusted EBITDA at the Gate level or higher, each Named

Executive Officer would have been eligible to receive a bonus payment for the attainment of specified

safety goals, up to a maximum payout of 130% of the safety goal target payout for such attainment, and

for the attainment of specified environmental goals, up to a maximum of payout 100% of the

environmental goal target payout for such attainment.

In February 2025 , the Committee determined the achievement of goals and approved final bonus

amounts payable to the Named Executive Officers under the Annual Cash Bonus Program for 2024 as

follows, reflecting the attainment of $348 million of 2024 Adjusted EBITDA (which amount is equal to

Adjusted EBITDA of $347 million , further adjusted by the Committee for purposes of the Annual Cash

Bonus Program by $0.5 million for the loss on the sale of an asset ) , or 98% of the target, and $96 million

of 2024 Free Cash Flow, or 74% of the target:

2024 Annual Cash Bonus Program	% of 2024 Adjusted EBITDA Target	% of 2024 Free Cash Flow Target	% of 2024 Safety Target	% of 2024 Environmental Target	% of 2024 Overall Target
Performance	98%	74%	108%	90%	—
Payout	95%	58%	108%	90%	87%

Long-Term Incentive Compensation

Each year since 2006, the Committee has used annual service-based awards of restricted stock units,

which are settled in shares of our Common Stock, and performance-based awards of performance units,

which are paid (to the extent earned) in cash, as employee compensation elements for our executive

officers and other employees.

Table of Contents

The Committee established the following objectives for our long-term incentive program:

• deliver competitive economic value;

• manage annual share utilization;

• preserve the alignment of the executives’ financial and shareholding interest with those of our

stockholders ;

• attract and retain executives and other key employees;

• focus management attention on specific performance measures that have a strong correlation with

the creation of stockholder value; and

• provide that, in general, approximately one-half of executives’ long-term incentive awards at target

be performance-based.

As in prior years, the 2024 restricted stock unit and performance unit awards were made subject to award

agreements on terms approved by the Committee and are scheduled to vest in full on the third

anniversary of the grant date, subject to earlier vesting in certain circumstances, as described in

“ Potential Payments on Termination or Change of Control ” below. At the notional value of $100 per

performance unit for achievement of performance goals at target level, the performance unit awards for

2024 comprised 50% of the estimated grant-date total value of the 2024 long-term incentive awards to

the Named Executive Officers.

The Committee sets long-term incentive values each year based on a review of market information

provided by the Compensation Consultant. In February 2024 , the Committee approved an increase to Mr.

Childress’ long-term incentive participation rate effective January 1, 2024 from 125% to 130% . This

increase was made in consideration of compensation benchmarking data provided by the Compensation

Consultant. Otherwise, any other increases to the target dollar value of long-term incentive awards for

each of the Named Executive Officers in 2024 , were the result of increased base salaries for 2024 . The

table below shows 2024 target long-term incentives for each Named Executive Officer and the breakout

between restricted stock unit awards (“RSU Awards”) and performance unit awards (“Performance Unit

Awards”):

Name	Target LTI Award (as a Percentage of Base Salary)	Dollar Value of Target Total Long- Term Incentive Award	Dollar Value of Target RSU Award	Number of Shares Underlying Target RSU Award (1)	Dollar Value of Target Performance Unit Awards

(1) The Compensation Committee determines the number of shares underlying each award by dividing such

target value by the average closing price of our Common Stock for a period of 20 trading days preceding

the date of the Committee’s approval of the award.

Since 2006, the Committee has not used annual awards of stock options as an element of employee

compensation for our executive officers and other employees. Accordingly, no stock options or stock

appreciation rights were awarded in 2024 . We therefore (i) do not grant, and have not granted, stock

options in anticipation of the release of material nonpublic information, (ii) we do not time, and have not

timed, the release of material nonpublic information based on stock option grant dates or for the purpose

of affecting the value of executive compensation and (iii) we do not take, and have not taken, material

nonpublic information into account when determining the timing and terms of stock options. As stock

options have not been an element of employee compensation for a significant amount of time, we do not

have a formal policy with respect to the timing of stock option grants, and we did not grant stock options

or stock appreciation rights in 2024 .

2024 Restricted Stock Units

Each restricted stock unit awarded in February 2024 represents the equivalent of one share of our

Common Stock but carries no voting or dividend rights. Settlement of vested restricted stock units will be

made in shares of our Common Stock, with some shares withheld to satisfy tax withholding requirements,

as soon as administratively practicable following the third anniversary of the grant date or certain

terminations of employment (as described in “ Potential Payments on Termination or Change of Control ”

below). The Committee determines the target value of the restricted stock unit award based on a fixed

percentage of the Named Executive Officer’s salary, which is then divided by the average closing price of

Oceaneering’s Common Stock on the New York Stock Exchange over a period of 20 trading days

preceding the Committee’s approval of the award (the “Reference Price”) to determine the number of

restricted stock units granted. The Reference Price may differ from the aggregate grant-date fair value of

restricted stock units awarded to the Named Executive Officers, which is reflected in the “Stock Awards”

column of the “Summary Compensation Table” and “Grant Date Fair Value of Stock Awards” column of

the “Grants of Plan-Based Awards” table below.

2024 - 2026 Performance Units

Each performance unit awarded in February 2024 is subject to the achievement of Committee-approved

financial goals and stock performance measures over a three-year performance period. The goals and

measures to be used as the basis for determining the final value of the performance units awarded in

2024 are based on (1) Cumulative Adjusted EBITDA (which is the sum of Adjusted EBITDA (as defined

for purposes of our 2024 cash bonus program) for each of the three calendar years in the performance

period) and (2) Total Shareholder Return or “ TSR ” (as defined in the award agreement ) relative to a

performance peer group selected by the Committee in consultation with the Compensation Consultant

(“ Relative TSR ”), in each case over the three-year period from January 1, 2024 , through December 31,

2026 (the “Performance Period”). Those measures were selected because of the Committee’s belief that

they have a strong correlation to the creation of stockholder value. The target amount of Cumulative

Adjusted EBITDA during the three-year Performance Period was selected because it was three times the

2024 Adjusted EBITDA then expected to be achieved. The amounts of Cumulative Adjusted EBITDA and

Relative TSR over the Performance Period necessary to achieve the threshold, target and maximum level

goals for these performance measures and corresponding amounts payable are as follows:

Performance Measures	Weight	Threshold	Target	Maximum
Cumulative Adjusted EBITDA	70%	$852 million	$1,065 million	$1,598 million
Relative TSR	30%	30th Percentile	50th Percentile	Above 90th Percentile
Payout as a % of Target (1)	—	50%	100%	200%

(1) A final value of zero is attributed to below-threshold performance of either performance measure.

Each performance unit has a target value of $100 and the final value of each performance unit may range

from $0 to $200 , with the threshold, target, and maximum levels of achievement of the performance goals

valued at $50 , $100 , and $200 , respectively. The actual final value of vested performance units will be

determined by the Committee and payable in cash. Regardless of the actual final value determined, if

Oceaneering’s TSR for the Performance Period is negative, then the amount attributable to Relative TSR

may not exceed the target level.

The estimated future payout of the performance unit awards to Named Executive Officers, if each of the

performance measures is achieved at the threshold, target, or maximum level, is reflected in the

“Estimated Future Payouts Under Non-Equity Incentive Plan Awards” column of the “Grants of Plan-

Based Awards” table below. Settlement of vested performance units is made in cash as soon as

administratively practicable following the third anniversary of the grant date or, if earlier, certain

terminations of employment (as described in “ Potential Payments on Termination or Change of Control ”

below).

2022 - 2024 Performance Units

The Committee used Cumulative Adjusted EBITDA and Relative TSR as performance measures for the

three-year performance units awarded in 2022 , which had a performance period beginning on January 1,

Table of Contents

2022 , and ending on December 31, 2024 . The threshold, target and maximum achievement levels were

set as follows:

Weight	Cumulative Adjusted EBITDA — 80%			Relative TSR — 20%
	Goal	Payout	Contribution Value	Goal	Payout	Contribution Value
Threshold	$589 million	50%	$40	30th Percentile	50%	$10
Target	$737 million	100%	$80	50th Percentile	100%	$20
Maximum	$1,105 million	200%	$160	Above 90th Percentile	200%	$40

The payout of the 2022 - 2024 performance units approved by the Committee reflected the attainment of

performance measures as follows.

Performance Measures	Weight	Attainment	Attainment and Payout as % of Target
Cumulative Adjusted EBITDA	80%	$867 million (1)	135%
Relative TSR	20%	67th Percentile ( 6th out of 16 peers )	142%
Overall Weighted Payout	—	—	137%

(1) Includes an adjustment in each year of the performance period for foreign exchange gain as well as an

adjustment in each of 2022 and 2024 for loss on the sale of an asset.

The final value of the performance units paid to the Named Executive Officers in 2024 in satisfaction of

the performance units awarded in 2022 is reflected in cash payments shown in the “Non-Equity Incentive

Plan Compensation” column of the “Summary Compensation Table.”

Perquisites

We provide executive officers with perquisites and other benefits that we believe are reasonable and

consistent with our overall compensation program to enable us to attract and retain employees for key

positions. The Committee periodically reviews the levels of perquisites and other personal benefits

provided to our executive officers. The perquisites provided to the Named Executive Officers in 2024 and

our incremental cost to provide those perquisites are set forth in the “All Other Compensation” column of

the “Summary Compensation Table” below and the related footnotes to that table.

Post-Employment Compensation Programs

Retirement Plans

We maintain a 401(k) plan and a nonqualified deferred compensation plan, known as the Supplemental

Executive Retirement Plan (the “SERP”). All of our employees who meet the eligibility requirements may

participate in our 401(k) plan. Each of the Named Executive Officers participated in our 401(k) plan in

2024 . Participation in the SERP includes Named Executive Officers and other key employees selected for

participation by the Committee. The SERP was established to provide a benefit to our executives and

other key employees in excess of Code limits for our 401(k) plan in order to attract and motivate

participants to remain with us and provide retirement plan values that are competitive with those provided

by companies within the Compensation Peer Group. Under the SERP, we credit each participant’s

notional account with a percentage (determined by the Committee) of the participant’s base salary,

subject to vesting. A participant may elect to defer a portion of base salary and annual bonus for accrual

pursuant to the SERP. Amounts accrued under the SERP are adjusted for earnings and losses as if they

were invested in one or more deemed investments selected by the participant from those designated as

alternatives by a management committee established by our Board (the “ U.S. Benefits Administrative

Committee ”). A participant’s vested interest in the SERP is generally distributable upon termination. The

Table of Contents

percentages of base salary credited for our Named Executive Officers in 2024 were:

Name	SERP Participation (as a Percentage of Base Salary)
Roderick A. Larson	50%
Alan R. Curtis	25%
Martin J. McDonald	20%
Earl F. Childress	20%
Benjamin M. Laura	20%

In 2024 , the SERP participation levels for our Named Executive Officers, in each case as a percentage of

base salary, were consistent with those in 2023 . Please see the “ Nonqualified Deferred Compensation ”

table below and accompanying narrative for further information about the SERP and contributions to the

applicable Named Executive Officer’s account.

Change-of-Control Agreements

We have entered into change-of-control agreements with each of the Named Executive Officers and

certain other officers (the “Change-of-Control Agreements”). The Change of Control Agreements include

a change-of-control plan that we adopted in 2018 for executive officers and other key employees who

were not previously parties to change-of-control agreements with us (the “CoC Plan”) and preexisting

change-of-control agreements that we entered into with certain executive officers prior to adopting the

CoC Plan (the “Legacy CoC Agreements”).

The provisions of the Change-of-Control Agreements did not influence and were not influenced by the

other elements of compensation, as the change-of-control payments and benefits serve different

objectives.

We believe the benefits provided by the Change-of-Control Agreements promote long-term retention and

allow executives to focus on the best interests of Oceaneering and our stockholders , by providing

financial security to these officers in the event of a loss of employment in connection with a change of

control of our Company. The Change-of-Control Agreements are described in more detail in

“Compensation of Executive Officers — Potential Payments on Termination or Change of Control ” below.

Stock Ownership Guidelines

To align the interests of our directors, executive officers, and stockholders , we believe our directors and

executive officers should have a significant financial stake in Oceaneering. To further that goal, our Board

has adopted stock ownership guidelines requiring that our nonemployee directors and designated officers

maintain minimum ownership interests in Oceaneering relative to the cash retainer generally paid to

nonemployee directors (“Retainer”) or current annual base salary of the officer (“Base Salary”). Under the

guidelines, we expect each of our nonemployee directors and senior officers to own a number of shares

of our Common Stock having a market value or cost basis, whichever is greater, that is not less than a

multiple of the Retainer or Base Salary as provided in the following table .

Level	Multiple of Retainer or Base Salary
Nonemployee Directors	5
Chief Executive Officer	5
President, Chief Operating Officer, and Corporate Senior Vice Presidents	3
Other Senior Vice Presidents	2

The following forms of ownership are recognized in determining the number of shares of our Common

Stock owned by a nonemployee director or executive officer for purposes of satisfying the stock

ownership guidelines:

• direct ownership of shares;

• indirect ownership of shares, including stock or stock equivalents held in our retirement plan; and

Table of Contents

• vested and unvested shares of restricted stock and restricted stock units awarded under our long-

term incentive programs.

Nonemployee directors and officers have five years from the date of their initial election or appointment to

comply with the stock ownership guidelines. If a nonemployee director or officer does not meet the stock

ownership level within the specified time period, they will be prohibited from selling any stock acquired

through vesting of restricted stock or restricted stock units, or upon exercise of stock options, except to

pay for applicable taxes or the exercise price, until they satisfy the requirements. All of our current

nonemployee directors and Named Executive Officers are covered by this policy and (unless they are

within the initial five-year compliance period) currently satisfy the stock ownership guidelines applicable to

them.

Prohibitions on Derivatives Trading, Hedging, etc.

Oceaneering maintains a policy that prohibits all of its directors, officers and employees, including the

Named Executive Officers, from (1) engaging in “short sales” or trading in puts, calls or other options on

our Common Stock, (2) engaging in hedging transactions involving our Common Stock and (3) holding

shares of our Common Stock in a margin account or pledging shares of our Common Stock as collateral

for a loan.

Oceaneering has adopted an insider trading policy governing the purchase, sale, and other dispositions

of our Common Stock by our directors, officers and employees that we believe is reasonably designed to

promote compliance with insider trading laws, rules and regulations, and any NYSE listing standards

applicable to us. A copy of our insider trading policy was filed as Exhibit 19 to our most recent Annual

Report on Form 10-K. In addition, with regard to the Company trading in its own securities, it is the

Company’s policy to comply with the federal securities laws and any applicable NYSE listing standards.

Clawback Policy

In August 2023, the Committee recommended to the Board, and the Board approved, a policy for the

recovery of erroneously awarded compensation, or “clawback” policy, applicable to executive officers,

which superseded our prior clawback policy. The policy requires recovery of incentive-based

compensation received by current or former executive officers during the three fiscal years preceding the

date it is determined that the Company is required to prepare an accounting restatement, including to

correct an error that would result in a material misstatement if the error were corrected in the current

period or left uncorrected in the current period. The amount required to be recovered is the excess of the

amount of incentive-based compensation received over the amount that otherwise would have been

received had it been determined based on the restated financial measure.

Tax Deductibility of Pay

Section 162(m) of the Code generally disallows a deduction to public companies for annual

compensation over $1 million paid to a chief executive officer and certain other executive officers

(“covered employees”). It is therefore expected that any compensation deductions for our covered

executives, including our named executive officers, will be subject to a $1 million annual deduction

limitation. Although the deductibility of compensation is a consideration evaluated by the Committee, the

Committee believes it is important to preserve flexibility in designing compensation programs and that the

lost deduction on compensation payable in excess of the $1 million limitation for the Named Executive

Officers who are covered employees does not outweigh the benefit of being able to attract and retain

talented management. Accordingly, the Committee will continue to retain the discretion to approve

compensation that is subject to the $1 million deductibility limit.

Compliance with Internal Revenue Code Section 409A

Section 409A of the Code can impose significant additional taxes on the recipient of “nonqualified

deferred compensation” arrangements that do not meet specified requirements regarding both form and

operation. Some of the arrangements between Oceaneering and its executive officers and other

employees provide, or might be considered to provide, nonqualified deferred compensation. We seek to

ensure that our compensation arrangements are either exempt from or comply with Section 409A.

Nonqualified Deferred Compensation

Our SERP is an unfunded, defined contribution plan for selected executives and key employees of

Oceaneering, including the Named Executive Officers. Pursuant to our SERP, U.S. participants, including

the Named Executive Officers, may defer up to 85% of their base salaries and 90% of their annual cash

bonus amounts. We credit a participant’s notional account with a determined percentage of the

participant’s base salary, subject to vesting. Benefits under our SERP are based on the participant’s

vested portion of the applicable Named Executive Officer’s notional account balance at the time of

termination of employment. A participant vests in one-third of our credited amounts each year, subject to

accelerated vesting upon the soonest to occur of: (1) the date the participant has completed ten years of

participation; (2) the date that the sum of the participant’s age and years of participation equals 65; (3) the

date of termination of employment by reason of death or disability; and (4) the date of termination of

employment within two years following a change of control. Messrs. Larson, Curtis, and McDonald are

fully vested in their SERP accounts. All participants are fully vested in deferred base salary and bonus.

Amounts accrued under the SERP are adjusted for earnings and losses as if invested in one or more

deemed investments selected by the participants from those designated as alternatives by the U.S.

Benefits Administrative Committee , a management committee the members of which are selected by our

Board. The deemed investment vehicles are a variety of mutual fund variable accounts. Participants may

reallocate their notional accounts within that group of mutual fund variable accounts by notifying the third-

party administrative agent of our SERP. The administrative agent adjusts each participant’s account with

any hypothetical income, gain or loss and any payments or distributions attributable to such account on a

daily basis, or at such other times as the administrative agent determines, based on the performance of

the specific deemed investments selected from time to time by the participant. We do not provide any

“above market or preferential earnings” (as defined by SEC rules) on any amount of deferred

compensation pursuant to our SERP or otherwise.

For the year ended December 31, 2024 , as reported by the administrative agent of our SERP, the

deemed investment options available pursuant to our SERP generated hypothetical annual returns

(losses) ranging from 35.6% to 1.3% .

The following table provides information on our nonqualified deferred compensation plan. Amounts

shown are entirely attributable to our SERP.

Potential Payments on Termination or Change of Control

Pursuant to the applicable award agreement under which long-term incentive plans were granted, in the

event of a termination of a Named Executive Officer’s employment:

• due to death or disability, or, following a change in control, by the Company or by the Named

Executive Officer for “good reason,” unvested restricted stock units and performance units will vest,

with the performance units equal to the target value; or

• as a result of retirement after both December 15th of the year of grant and meeting a specified age

(or age and years of service) requirement, a pro-rata portion of unvested restricted stock units will

vest and a pro-rata portion of performance units will remain outstanding and eligible to be earned.

In addition, upon a change of control, the performance units will be deemed earned at their target value,

but will remain subject to the Named Executive Officer’s continued service through the original vesting

date.

Our Named Executive Officers are party to Change-of-Control Agreements (as defined in the CD&A

above): Messrs. Larson, Curtis, and McDonald as parties to Legacy CoC Agreements and

Messrs. Childress and Laura are participants in the CoC Plan. On a termination by our Company without

“cause” or by the Named Executive Officer for “good reason,” in each case in connection with a change of

control (as defined in the Change-of-Control Agreements), the Change-of-Control Agreements provide for

a lump sum payment equal to a multiple (three, in the case of Mr. Larson, and two, in the case of each of

our other Named Executive Officers) of the sum of:

• the officer’s highest base salary (under Legacy CoC Agreements, during the then-current year or

any of the three preceding years, and under the CoC Plan, during the period beginning 180 days

prior to and ending two years after the change of control);

• an amount equal to the Named Executive Officer’s target award under the then-current Annual

Cash Bonus Program;

• under the CoC Plan, the officer’s annualized premium for COBRA continuation coverage; and

• in the case of Mr. Larson, an amount equal to the maximum percentage of his annual base salary

contributed by us for him in our SERP for the then-current year multiplied by his highest base salary.

The Change-of-Control Agreements also provide that the Named Executive Officer would receive, at no

greater cost or expense to such officer: (a) under the officer’s Legacy CoC Agreement, benefits under all

other plans and programs in which the officer then participates for three years (in the case of Mr. Larson)

or two years (in the case of Messrs. Messrs. Curtis and McDonald ); or (b) under the CoC Plan, one year

of post-employment health insurance benefits (in the case of Messrs. Childress and Laura ).

Additionally, the Change-of Control Agreements include a provision (the “net better of provision”) which

provides that, in the event a Named Executive Officer is subject to the excise tax under Section 4999 of

the Code, the Named Executive Officer will receive a “net better of payment,” which is generally either (a)

provision in full of the payments and benefits to which the Named Executive Officer is entitled (and on

which the Named Executive Officer must pay the excise tax) or (b) provision of reduced payments in an

amount that results in the Named Executive Officer no longer being subject to the excise tax, whichever

alternative results in the greater net-after tax position for the Named Executive Officer.

The Legacy CoC Agreements provide that the benefits under all compensation plans and programs,

including restricted stock agreements, restricted stock unit agreements and performance unit

agreements, would be paid as if all contingencies for payment and maximum levels of performance had

been met.

For purposes of the Change-of-Control Agreements:

• “cause” generally includes:

◦ in the Legacy CoC Agreements, the final conviction by a court of competent jurisdiction of a

felony-grade crime involving moral turpitude related to employment with us; and

◦ in the CoC Plan, a material breach of the Named Executive Officer’s obligations under any

written agreement with the Company; a material violation of any of the Company’s policies,

Table of Contents

procedures, rules and regulations; the failure to perform, in any material respect, the Named

Executive Officer’s duties or responsibilities to the Company; the commission of fraud, theft,

embezzlement or misappropriation of funds or other assets of the Company; or the conviction

of, entry of a plea of guilty or no-contest to, or receipt of adjudicated probation or deferred

adjudication in connection with, a crime involving fraud, dishonesty or moral turpitude or any

felony;

• “good reason” generally includes an adverse change in status, title or position; a reduction in annual

base salary, Company SERP contribution level, annual bonus opportunity or aggregate long-term

compensation; certain Company failures to continue, adverse actions under or material reductions

of benefits under certain bonus plans and the SERP; a significant relocation of the principal place of

employment; the failure of a successor company to assume the Change-of-Control Agreement; and,

with respect to Legacy CoC Agreements, certain failures of contractual performance or restrictions

imposed by the Company; and

• a termination without “cause” or resignation for “good reason” is considered to be in connection with

a change of control if it occurs during the period: (a) under the Legacy CoC Agreements, beginning

one year prior to, and ending on the second anniversary of, the change of control and (b) under the

CoC Plan, beginning on the date that is 180 days prior to, and ending on the second anniversary of,

the change of control.

For purposes of the long-term incentive agreements, “good reason” generally means a 5% reduction in

aggregate total annual compensation from that in place immediately prior to a change of control; a

material reduction in scope of responsibilities; and a significant relocation of the principal place of

employment.

Assuming a termination date of December 31, 2024 , and, where applicable, using the closing price of our

Common Stock of $26.08 per share , which was the closing price of our Common Stock, as reported by

the NYSE, on Tuesday, December 31, 2024 (the last trading day of the year) , the tables below show

potential payments to each of the Named Executive Officers under the existing contracts, agreements,

plans or arrangements, whether written or unwritten, in the event of a termination of such executive’s

employment, including amounts payable pursuant to benefits or awards in which the Named Executive

Officers are already vested. Whether an excise tax liability arises will depend on the facts and

circumstances in existence at the time a change-of-control payment becomes payable and the tables

below do not reflect any “net better of payments.”

Table of Contents

(1) The amounts for each Named Executive Officer includes the lump-sum cash payment they would receive,

assuming no corresponding change in control that would otherwise trigger payments under the Change-of-

Control Agreements and subject to the execution of a release of claims, pursuant to the Company’s broad-

based severance plan that provides separation benefits to full-time, salaried employees of the Company

who are permanently and involuntarily terminated as a result of a reduction in force. The amount of this

cash payment equals a specified number of weeks of the employee’s base pay (up to a maximum of 52

weeks), depending on the number of continuous years of service with the Company. The amounts also

include the one-month subsidized COBRA payment that the Named Executive Officers would receive

pursuant to this severance plan.

(2) The amount for each Named Executive Officer reflects an amount equaling three times, for Mr. Larson , or

two times, for each of the other Named Executive Officers , the sum of: (a) their highest base salary; (b) the

target award they are eligible to receive under the Annual Cash Bonus Program for the then-current year;

and (c) for Mr. Larson, the maximum percentage of base salary contribution level by us for him in our SERP

for the then-current year multiplied by his highest base salary; plus for Messrs. Childress and Laura , the

annualized premium for COBRA continuation coverage. If applicable, the termination amount may be

reduced pursuant to the net better of provision .

(3) The amount for each Named Executive Officer reflects either (a) the estimated value of the benefit to them

to receive the same level of medical, life insurance and disability benefits for a period of 36 months, for

Mr. Larson ; 24 months, for Messrs. Curtis and McDonald ; or (b) the benefit to them to receive the same

basic medical, dental, and vision coverage that would be payable after termination pursuant to the Change

of Control Plan for a period 12 months, for Messrs. Childress and Laura .

(4) The amount for each Named Executive Officer reflects the value of shares of Common Stock that would be

delivered for outstanding unvested restricted stock units for which vesting would be accelerated pursuant to

the executive’s restricted stock unit agreements.

(5) The amount for each Named Executive Officer reflects the value of shares of Common Stock that would be

delivered for outstanding unvested restricted stock units for which vesting would be accelerated pursuant to

the executive’s restricted stock unit agreements and, if applicable, Legacy CoC Agreement.

(6) Upon death or disability, vesting of any unvested portion of outstanding performance units would be

accelerated, and the final value would be equal to the target value of $100 per unit.

(7) Vesting of any unvested portion of outstanding performance units would be accelerated, and the final value

of the units would be equal to the maximum value of $200 per unit if the executive is party to a Legacy CoC

Agreement or, if not party to a Legacy CoC Agreement, $100 per unit pursuant to the applicable award

agreement.

(8) The amount for each Named Executive Officer reflects the accumulated account values (including gains

and losses) of contributions by the Named Executive Officer and Oceaneering for vested amounts and by

Oceaneering for unvested amounts. Messrs. Larson, Curtis, and McDonald were fully vested in their

respective SERP accounts. For more information on SERP amounts, please see “— Nonqualified Deferred

Compensation ” above.

(9) The amount for Mr. McDonald reflects the value of shares of Common Stock that would be delivered for

outstanding restricted stock units for which vesting occurred prior to December 31, 2024 , pursuant to his

restricted stock unit agreements.

(10) The amount shown for Mr. McDonald reflects an amount in cash equal to the actual payout for the

performance units awarded to him in 2022 , all of which vested prior to December 31, 2024 , by reason of his

having previously attained Retirement Age (as defined in the award agreement). Because the final value of

the performance units awarded to Mr. McDonald in 2023 and 2024 will not be known until the completion of

the applicable performance periods, this table reflects a zero value for such awards. The notional value of

the vested portion of these performance units is equal to $272,800 or $100 per unit for achievement of

performance goals at target level. For more information regarding performance units, please see

“ Compensation Discussion & Analysis — Executive Compensation Components — Long-Term Incentive

Compensation ” above.

CEO Pay Ratio

The table below sets forth comparative information for the year ended December 31, 2024 regarding:

(1) the actual annual total compensation of our Chief Executive Officer; (2) the median of the annual total

compensation of all employees of Oceaneering (including its consolidated subsidiaries), excluding our

Chief Executive Officer; and (3) a ratio comparison of those two amounts (the “CEO Pay Ratio”). These

amounts were determined in accordance with rules prescribed by the SEC, as explained below.

For purposes of determining our median employee, we used total cash compensation as determined from

payroll records for the period from November 1, 2023 , through October 31, 2024 (the “Measurement

Period” ) of our employees, other than our Chief Executive Officer. We did not take into account equity-

based incentive compensation awards, because less than 5% of our employees receive those awards.

Except as noted below, we included all Oceaneering employees (whether employed on a full-time, part-

time, or seasonal basis) as of the last day of the Measurement Period, and, other than annualizing

compensation of employees who were not employed for the full Measurement Period, w e did not make

any assumptions, adjustments or estimates with respect to total cash compensation. We excluded from

the median employee determination the non-U.S. employees (who collectively represented fewer than

5% of the approximately 11,489 total employees as of the Measurement Date) from the following

jurisdictions: Azerbaijan ( 49 ); Canada ( 64 ); China ( 1 ); Guyana ( 12 ); Indonesia ( 99 ); Malaysia ( 36 );

Mexico ( 18 ); Nigeria ( 13 ); Oman ( 19 ); Papua New Guinea ( 20 ); Qatar ( 153 ); and Thailand ( 9 ).

After identifying the median employee, based on the process described above, we calculated annual total

compensation for that employee using the same methodology we used for determining total

compensation for 2024 for the Named Executive Officers as set forth in the “Summary Compensation

Table.”

Annual Total Compensation	Amount
Chief Executive Officer (A)	$7,401,994
Median of all employees (excluding our Chief Executive Officer) (B)	$73,444
Ratio of (A) to (B)	101

As described above, our Chief Executive Officer’s actual total compensation for 2024 benefited from

achieving above-target performance metrics. His target total compensation for 2024 was $6,364,753 . The

ratio of his target total compensation to the median of the annual total compensation of all employees for

2024 (excluding our Chief Executive Officer), shown above, was 87 :1. For this purpose, our Chief

Executive Officer’s target total compensation for 2024 was calculated as the sum of Mr. Larson ’s base

salary, the target values of his annual cash bonus opportunity and performance unit award, the grant-date

fair value of his restricted stock unit award, and all other compensation Mr. Larson earned in 2024 . The

compensation of the median employee identified for 2024 did not include incentive compensation. The

difference between the target ratio and that reported above reflects the amounts paid to our Chief

Executive Officer under our incentive programs in 2024 , which paid above target.

Table of Contents

Proposal 1: Election of Class III Directors

Our Board unanimously recommends a vote FOR election of the nominees for Class III directors, Roderick A. Larson, M. Kevin McEvoy, and Paul B. Murphy, Jr.

Our Restated Certificate of Incorporation divides our Board into three classes, each consisting as nearly

as possible of one-third of the members of the whole Board. There are currently three directors in each

Class. The members of each class serve for three years following their election, with one class being

elected each year. Three Class III directors are to be elected at the 2025 Annual Meeting.

In accordance with our Bylaws , directors are elected by a plurality of the votes cast. However, our

Corporate Governance Guidelines provide that, in an uncontested election of directors, any director

nominee who does not receive a “for” vote by a majority of shares present in person or by proxy and

entitled to vote and actually voting on the matter shall promptly tender their resignation to the Nominating,

Corporate Governance & Sustainability Committee of our Board, subject to acceptance by the Board. The

Nominating, Corporate Governance & Sustainability Committee will then make a recommendation to the

Board with respect to the director’s resignation and the Board will consider the recommendation and take

appropriate action within 120 days from the date of the certification of the election results. Withholding of

authority to vote for a director nominee and broker “non-votes” marked on proxy cards will not be counted

in the election and will have no effect on the election of directors.

The persons named as agents and proxies in the accompanying proxy card intend to vote all proxies

received in favor of the election of the nominees named below, except in any case where authority to vote

for the directors is withheld. Although we have no reason to believe that the nominees will be unable to

serve as directors, if any nominee withdraws or otherwise becomes unavailable to serve, the persons

named as proxies will vote for any substitute nominee our Board designates.

Each Class III director will serve until the 2028 Annual Meeting of Stockholders or until a successor has

been duly elected and qualified. The terms of office of the directors in Classes I and II will expire at the

Annual Meetings of Stockholders to be held in 2026 and 2025 , respectively.

Proposal 2: Advisory Vote to Approve

Executive Compensation

Our Board unanimously recommends a vote FOR the approval of the compensation of our Named Executive Officers as disclosed in this Proxy Statement

As required by Section 14A(a)(1) of the Exchange Act, we are providing our stockholders the opportunity

to vote to approve, on a non-binding, advisory basis, the compensation of our Named Executive Officers

as disclosed in this Proxy Statement. The vote on this resolution is not intended to address any specific

element of compensation; rather, the vote on an advisory basis relates to the compensation of the Named

Executive Officers as described in this Proxy Statement in accordance with the rules of the SEC.

As described in more detail under the “ Compensation Discussion & Analysis ” section of this Proxy

Statement above, our compensation program for Named Executive Officers is designed to attract and

retain key executives, motivate them to achieve our short-term and long-term objectives without exposing

us to excessive or unnecessary risk, and align their interest with our stockholders ’ interests. To achieve

these goals, we’ve designed our executive compensation program to deliver a competitive package and

to reward our key executives for superior performance.

The vote on this resolution is an advisory, non-binding vote. However, our Compensation Committee,

which is responsible for designing and overseeing the administration of our executive compensation

program, and our Board will consider the outcome of the vote as an indicator of how well our

compensation philosophy and programs align with the interests of our stockholders .

Accordingly, we ask our stockholders to vote on the following resolution:

RESOLVED, that Oceaneering’s stockholders approve, on an advisory basis, the compensation of the

Named Executive Officers, as disclosed in Oceaneering’s Proxy Statement for its 2025 Annual

Meeting of Stockholders pursuant to the compensation disclosure rules of the Securities and

Exchange Commission, including the Compensation Discussion & Analysis , the 2024 Summary

Compensation Table and the other compensation-related tables and accompanying narrative

disclosures.

In accordance with our Bylaws, the approval of this proposal requires the affirmative vote of a majority of

the shares of Common Stock, present in person or by proxy and entitled to vote on the proposal at the

2025 Annual Meeting of Stockholders. Because abstentions are counted as present for the purpose of

the vote on this proposal, they have the same effect as votes “AGAINST” this proposal. Broker “non-

votes” will have no effect on this vote.

The persons named as agents and proxies in the accompanying proxy card intend to vote such proxy in

favor of the compensation of our Named executive Officers unless a choice is set forth therein or unless

an abstention or broker “non-vote” is indicated therein.

Proposal 3: Ratification of Appointment of

Independent Auditors

Our Board unanimously recommends a vote FOR this proposal.

The Audit Committee of the Board has appointed Ernst & Young LLP, independent certified public

accountants, as independent auditors of Oceaneering for the year ending December 31, 2025 . Although

we are not required to seek stockholder approval of the appointment, it has been our practice to do so.

No determination has been made as to what action the Audit Committee would take if our stockholders

failed to ratify the appointment. The Audit Committee retains the discretion to appoint a new independent

registered public accounting firm at any time if the Audit Committee concludes such a change would be in

the best interests of Oceaneering. Representatives of Ernst & Young LLP will be present at the meeting,

will be given the opportunity to make a statement if they so desire and will be available to respond to

appropriate questions of any stockholders .

In accordance with our Bylaws, the approval of the proposal to ratify the appointment of

Ernst & Young LLP as independent auditors of Oceaneering for the year ending December 31, 2025 ,

requires the affirmative vote of a majority of the shares of Common Stock voted on this proposal at the

meeting. Accordingly, abstentions will not affect the outcome of this proposal.

The persons named as agents and proxies in the accompanying proxy card intend to vote such proxy in

favor of the ratification of the appointment of Ernst & Young LLP as independent auditors of Oceaneering

for the year ending December 31, 2025 , unless a contrary choice is set forth thereon or unless an

abstention is indicated thereon.

Independent Auditors’ Fees

The following table shows the fees incurred by Oceaneering for the audit and other services provided by

Ernst & Young LLP for 2024 and 2023 .

Fees Incurred for Audit and Other Services Provided by Ernst & Young LLP	2024	2023
Audit Fees (1)	$ 2,774,000	$ 2,610,000
Audit-Related Fees (2)	15,000	77,800
Tax Fees (3)	148,000	150,000
Total	$ 2,937,000	$ 2,837,800

(1) Audit Fees consisted of fees for professional services provided in connection with: (a) the audit of our

financial statements for the years indicated and the reviews of our financial statements included in our

Forms 10-Q during those years; and (b) audit services provided in connection with other statutory filings,

consents and other services related to SEC matters.

(2) Audit-Related Fees consisted of fees for accounting consultations and attestation services related to

regulatory compliance.

(3) Tax Fees consisted primarily of tax compliance services and advice with respect to various foreign

corporate tax matters.

The Audit Committee has concluded that Ernst & Young LLP ’s provision of services that were not related

to the audit of our financial statements in 2024 was compatible with maintaining that firm’s independence

from us.

The Audit Committee has established a policy that requires pre-approval of the audit and non-audit

services performed by our independent auditors. Unless a service proposed to be provided by the

independent auditors has been pre-approved by the Audit Committee under its pre-approval policies and

procedures, it will require specific pre-approval of the engagement terms by the Audit Committee. Under

Table of Contents

the policy, pre-approved service categories are generally provided for up to 12 months and must be

detailed as to the particular services provided and sufficiently specific and objective so that no judgments

by management are required to determine whether a specific service falls within the scope of what has

been pre-approved. In connection with any pre-approval of services, the Audit Committee is required to

review the fees and other terms for the services provided by the independent auditors. The Audit

Committee does not delegate to management any of its responsibilities to pre-approve services

performed by our independent auditors.

None of the services related to the Audit-Related Fees or Tax Fees described above were approved by

the Audit Committee pursuant to the waiver of pre-approval provisions set forth in applicable rules of the

SEC.

The Audit Committee has delegated to the chair of the Audit Committee the authority to pre-approve

audit-related and non-audit-related services not prohibited by law to be performed by Ernst & Young LLP ,

provided that the chair is required to report any decisions to pre-approve such audit-related or non-audit-

related services and fees to the full Audit Committee at its next regular meeting.

Report of the Audit Committee

During the year ended December 31, 2024 , the Audit Committee of our Board was comprised of the

directors named below. Each member of the Audit Committee is an independent director as defined by

applicable Securities and Exchange Commission rules and New York Stock Exchange listing standards.

The Audit Committee met seven times during the year ended December 31, 2024 . The Audit Committee

reviewed and discussed with management and Ernst & Young LLP , Oceaneering’s independent

registered public accounting firm, all of Oceaneering’s earnings releases in 2024 prior to the public

release of those earnings releases. In addition, the chair of the Audit Committee reviewed and discussed

with management the interim financial information included in Oceaneering’s quarterly reports on Form

10-Q for the periods ended March 31, 2024 , June 30, 2024 , and September 30, 2024 , prior to their being

filed with the Securities and Exchange Commission.

The Audit Committee reviewed and discussed with management and Ernst & Young Oceaneering’s

consolidated financial statements for the year ended December 31, 2024 . Members of management

represented to the Audit Committee that Oceaneering’s consolidated financial statements were prepared

in accordance with generally accepted accounting principles. The Audit Committee discussed with

Ernst & Young matters required to be discussed under the standards of the Public Company Accounting

Oversight Board. The Audit Committee also reviewed and discussed, with management and

Ernst & Young, our management’s report and Ernst & Young’s report on internal control over financial

reporting in accordance with Section 404 of the Sarbanes-Oxley Act.

Ernst & Young provided to the Audit Committee the written disclosures and the letter required by the

applicable requirements of the Public Company Accounting Oversight Board regarding Ernst & Young’s

independence, and the Audit Committee discussed with Ernst & Young its independence from

Oceaneering. The Audit Committee concluded that Ernst & Young’s provision of non-audit services to

Oceaneering and its affiliates is compatible with Ernst & Young’s independence.

Based on the Audit Committee’s discussions with management and Ernst & Young and the Audit

Committee’s review of the items referred to above, the Audit Committee recommended to Oceaneering’s

Board that Oceaneering’s audited consolidated financial statements as of and for the year ended

December 31, 2024 , be included in our Annual Report on Form 10-K for the year ended December 31,

2024 , filed with the SEC.

Proposal 4: Approval of the 2020 Incentive

Pla n as Amended and Restated

The Board unanimously recommends a vote FOR approval of the Amended and Restated 2020 Incentive Plan of Oceaneering International, Inc.

Our Board adopted the 2020 Incentive Plan of Oceaneering International, Inc. (the “Incentive Plan”) on

February 21, 2020 , and our stockholders approved the Incentive Plan at the 2020 Annual Meeting. Our

Board adopted the 2020 Incentive Plan of Oceaneering International, Inc., as amended and restated May

9, 2025 (the “ Incentive Plan as Amended and Restated ”) on February 21, 2025 , subject to the approval of

our stockholders at the 2025 Annual Meeting.

We are asking our stockholders to approve the Incentive Plan as Amended and Restated , effective as of

the date of the 2025 Annual Meeting (the “Effective Date”), primarily to add an additional 4,200,000

shares to those authorized for award under the Incentive Plan and to make minor administrative and tax

updates.

In accordance with our Bylaws, the adoption of the proposal to approve the Incentive Plan as Amended

and Restated requires the affirmative vote of a majority of the shares of Common Stock present in person

or by proxy and entitled to vote on this proposal at the 2025 Annual Meeting. Because abstentions are

counted as present for purposes of the vote on this proposal but are not votes “FOR” this proposal, they

have the same effect as votes “AGAINST” this proposal. Broker non-votes will have no effect on the vote.

The persons named as agents and proxies in the accompanying proxy card intend to vote such proxy

FOR approval of the Amended and Restated 2020 Incentive Plan of Oceaneering International, Inc.,

unless a contrary choice is set forth thereon or unless an abstention or broker “non-vote” is indicated

thereon.

Overview of the Incentive Plan as Amended and Restated

The Incentive Plan as Amended and Restated is integral to the compensation strategy that is described in

the “ Compensation Discussion & Analysis ” section of this Proxy Statement above. Despite our

conservative use of equity, after five years we have nearly exhausted the shares available for use by us

under the Incentive Plan. We are seeking stockholder approval to provide Oceaneering with enough

shares to support an estimated six years of awards under the Incentive Plan as Amended and Restated .

See also “— Summary of the Incentive Plan as Amended and Restated — Shares Reserved.”

Our Board believes the Incentive Plan as Amended and Restated will be important to our long-term

success by helping us to attract and retain key employees, to attract and retain qualified directors, to

encourage the sense of proprietorship of such employees and directors, and to stimulate the active

interest of such persons in the development and financial success of Oceaneering and its subsidiaries.

These objectives are to be pursued through grants of incentive and stock-based awards under the plan.

The following description of the Incentive Plan as Amended and Restated is a summary of various

provisions and is qualified in its entirety by reference to the Incentive Plan as Amended and Restated ,

which is attached to this Proxy Statement as Appendix A.

As of January 1, 2025 , Oceaneering and its subsidiaries collectively had approximately 10,400 full-time

employees, including 13 executive officers and eight nonemployee directors.

Summary of the Incentive Plan as Amended and Restated

Purpose. The Incentive Plan as Amended and Restated is designed to attract and retain key employees

of Oceaneering and its subsidiaries and qualified directors of Oceaneering, and to encourage the sense

of proprietorship of such employees and directors and stimulate the active interest of such persons in the

development and financial success of Oceaneering and its subsidiaries through grants of incentive and

stock-based awards under the plan.

Administration. The Incentive Plan as Amended and Restated is administered by the Committee,

except that our full Board administers awards for our nonemployee directors. The Committee will

determine participants and the types and amounts of awards such participants will be granted, has the

authority to interpret the Incentive Plan as Amended and Restated, to adopt rules, regulations, and

guidelines as it deems necessary and may provide for the extension or exercisability of an award,

accelerate the vesting or exercisability of an award, or lessen restrictions on an award.

Delegation. The Committee may delegate its authority or duties under the Incentive Plan as Amended

and Restated to one or more subcommittees, another committee of the Board, the Company’s President

and Chief Executive Officer or to other senior officers of the Company, pursuant to such conditions or

limitations as the Committee may establish; provided, however, that the Committee may not delegate to

any officer of the Company the authority to make awards to any officer of the Company.

Awards. The Incentive Plan as Amended and Restated provides for various types of awards to be

granted to participants including, options to purchase shares of Common Stock, stock appreciation rights,

stock awards (which include shares of Common Stock or units denominated in shares of Common Stock,

including restricted stock, restricted stock units and performance awards settled in shares of Common

Stock) and cash awards. Awards may be granted as alternatives to or in replacement of awards

outstanding under the Incentive Plan as Amended and Restated or any other plan or arrangement of the

Company or any of its subsidiaries, including any acquired entity.

Although the Incentive Plan as Amended and Restated allows for the grant of options and stock

appreciation rights, we expect to continue to deliver long-term incentives through grants of restricted

stock, restricted stock units and performance units.

Table of Contents

Minimum Vesting. Awards other than cash awards will have a minimum vesting period or restriction

period, as applicable, of one year from the date of grant, provided that: (1) the Committee may provide

for earlier vesting or termination of the restriction period following a Change of Control or upon

termination of a participant’s employment or service by reason of death, disability or retirement; and (2)

awards with respect to up to 5% of the shares of Common Stock authorized for grant pursuant to the

Incentive Plan as Amended and Restated may have a vesting period or restriction period, as applicable,

of less than one year.

Shares Reserved. Subject to the adjustments described below, 8,700,000 shares will be authorized for

issuance under Incentive Plan as Amended and Restated . The number of shares of Common Stock that

are the subject of awards under the Incentive Plan as Amended and Restated that are canceled,

terminated, forfeited, or expire unexercised shall again immediately become available for Awards

hereunder as if such shares had never been the subject of an award. The number of shares of Common

Stock available under the Incentive Plan as Amended and Restated will not be increased by shares of

Common Stock tendered, surrendered or withheld in connection with (1) the exercise or settlement of an

award or (2) Oceaneering’s tax withholding obligations.

Award Limits. Under the Incentive Plan as Amended and Restated , no nonemployee director may be

granted, during any single calendar year, Awards having an aggregate value, determined on each

applicable grant date, when added to all cash compensation paid to such director, other than in

connection with the post-retirement payment associated with prior service as an officer or other employee

of Oceaneering, during the same calendar year, in excess of $1,500,000 .

Adjustments. In the event of certain corporate transactions, including the subdivision or consolidation

of outstanding shares of Common Stock, declaration of a stock dividend or other stock split,

recapitalization or capital reorganization, consolidation or merger, adoption of any plan of exchange

affecting the Common Stock or any distribution to holders of Common Stock or securities or property, the

Incentive Plan as Amended and Restated provides for proportional or appropriate adjustments, as

applicable, in the number of shares of Common Stock subject to and, if applicable, the exercise price of,

awards, as well as the maximum award limits and number of shares available under the Incentive Plan as

Amended and Restated .

In addition, in the event of a corporate merger, consolidation, acquisition of property or stock, separation,

reorganization or liquidation, the Committee may, among other things, make equitable adjustments to

awards or other provisions for the disposition of awards, and has the discretion to provide for the

substitution of a new award or other arrangement for an award or the assumption of an award, provide for

the accelerated vesting or exercisability of an award and the cancellation thereof in exchange for the

payment of a reasonable and approximate value thereof, or cancel any awards in exchange for cash

equal to the fair market value (as defined in the Incentive Plan as Amended and Restated) (with

underwater options able to be cancelled for no consideration).

Stock Options. The Committee determines, in connection with each option granted to employees, the

exercise price (which may not be less than the fair market value of the Company’s Common Stock on the

date of the grant), the terms and conditions of exercise, the expiration date, restrictions on transfer of the

option, and other provisions not inconsistent with the Incentive Plan as Amended and Restated . The term

of an option will not exceed ten years from the date of grant. The full Board makes the same

determinations with respect to nonqualified options granted to nonemployee directors.

Stock Appreciation Rights. The Committee is authorized to grant stock appreciation rights, or SARs,

to employees and the full Board may grant SARs to nonemployee directors. Each SAR entitles the

participant, on exercise of the SAR, to receive in cash or shares of Common Stock a value equal to the

excess of the fair market value of a specified number of shares of Common Stock at the time of exercise

over the exercise price established by the Committee or Board, as applicable. The term of a SAR will not

exceed ten years from the date of grant. A SAR may be granted in tandem with an option, subject to such

terms and restrictions as established by the Committee or Board, as applicable.

Table of Contents

Stock Awards and Cash Awards. The Incentive Plan as Amended and Restated authorizes the

Committee to grant employees stock awards (consisting of shares of Common Stock or of a right to

receive shares of Common Stock, or their cash equivalent or a combination of both, in the future,

including restricted stock, restricted stock units and performance awards settled in shares) and cash

awards, and the Board is authorized to make such grants to nonemployee directors. Those awards may

be subject to the terms and conditions, restrictions, and contingencies, not inconsistent with the Incentive

Plan as Amended and Restated , as may be determined by the Committee or Board, as applicable.

Performance Awards. Any award available under the Incentive Plan as Amended and Restated may

be made as a performance award. Performance awards will be based on achievement of such goals and

will be subject to such terms, conditions, and restrictions as the Committee (or the Board with respect to

nonemployee director awards) will determine.

Treatment upon a Change of Control. The treatment of awards on the occurrence of a Change of

Control will be determined in the sole discretion of the Committee or the Board and will be described in

the applicable award agreements.

Transferability. Except as otherwise determined by the Committee (or the Board, in the case of awards

to non-employee directors) and specified in a participant’s award agreement, no award may be assigned

or otherwise transferred except by will or by the laws of descent and distribution or pursuant to a qualified

domestic relations order.

Duration; Plan Amendments. The Incentive Plan as Amended and Restated has a term of ten years

from the date of the Company’s 2025 annual meeting of stockholders. The Board may at any time

amend, modify, suspend or terminate the Incentive Plan as Amended and Restated (and the Committee

may amend or modify an award agreement) but in doing so cannot materially adversely affect any

outstanding award without the participant’s written consent or make any amendment without stockholder

approval, to the extent such stockholder approval is required by applicable legal requirements or the

requirements of the securities exchange on which the Company’s stock is listed. If the stockholders of

Oceaneering fail to approve the Incentive Plan as Amended and Restated at this annual meeting, the

Incentive Plan as Amended and Restated will be of no force and effect and the Incentive Plan will

continue in force and effect.

Certain Federal Income Tax Consequences of Awards Under the Incentive

Plan as Amended and Restated

The following summary is based on current interpretations of existing federal income tax laws. The

discussion below is not purported to be complete, and it does not discuss the tax consequences arising in

the context of the participant’s death or the income tax laws of any locality, state, or foreign country in

which a participant’s income or gain may be taxable.

Options. On grant of an option, the optionee will not recognize income for tax purposes and

Oceaneering will not receive any deduction. On the exercise of a nonqualified option, the optionee

recognizes taxable income (subject to withholding) in an amount equal to the difference between the fair

market value of the shares of Common Stock acquired on the date of exercise and the exercise price. On

any sale of those shares by the optionee, any difference between the sale price and the fair market value

of the shares on the date of exercise of the nonqualified option will be treated generally as capital gain or

loss. On exercise of a nonqualified stock option, Oceaneering is entitled to a deduction in an amount

equal to the income recognized by the employee.

Stock Appreciation Rights. The amount of any cash or the fair market value of any shares of

Common Stock received by the holder on the exercise of SARs will be subject to ordinary income tax in

the year of receipt, and Oceaneering will be entitled to a deduction for that amount.

Restricted Stock. A participant generally recognizes no taxable income at the time of an award of

restricted stock. A participant may, however, make an election under Section 83(b) of the Code to have

the grant taxed as compensation income at the date of receipt, with the result that any future appreciation

Table of Contents

or depreciation in the value of the shares of stock granted may be taxed as capital gain or loss on a

subsequent sale of the shares. If the participant does not make a Section 83(b) election, the grant will be

taxed as compensation income at the full fair market value on the date the restrictions imposed on the

shares expire. Unless a participant makes a Section 83(b) election, any dividends paid to the participant

on the shares of restricted stock will generally be compensation income to the participant and deductible

by us as compensation expense. In general, we will receive an income tax deduction for any

compensation income taxed to the participant. To the extent a participant realizes capital gains, as

described above, we will not be entitled to any deduction for federal income tax purposes.

Restricted Stock Units. A participant who is granted a restricted stock unit will recognize no income

upon grant of the restricted stock unit. At the time the underlying shares of common stock (or cash in lieu

thereof) are delivered to a participant, the participant will recognize compensation income equal to the full

fair market value of the shares received. We will be entitled to an income tax deduction corresponding to

the compensation income recognized by the participant.

Cash Awards. Cash awards under the Incentive Plan as Amended and Restated are taxable income to

the participant for federal income tax purposes at the time of payment. The participant will have

compensation income equal to the amount of cash paid, and Oceaneering will have a corresponding

deduction for federal income tax purposes.

Certain Tax Code Limitations on Deductibility . In order for Oceaneering to deduct the amounts

described above, such amounts must constitute reasonable compensation for services rendered or to be

rendered and must be ordinary and necessary business expenses. The ability to obtain a deduction for

future payments under the Incentive Plan as Amended and Restated could also be limited by Code

Section 280G, which provides that certain excess parachute payments made in connection with a change

of control of an employer are not deductible. The ability to obtain a deduction for amounts paid under the

Incentive Plan as Amended and Restated could also be affected by Code Section 162(m), which limits

the deductibility for U.S. federal income tax purposes of compensation paid to certain employees to $1

million during any taxable year.

Code Section 409A . Code Section 409A generally provides that deferred compensation subject to

Code Section 409A that does not meet the requirements for an exemption from Code Section 409A must

satisfy specific requirements, both in operation and in form, regarding: (1) the timing of payment; (2) the

election of deferrals; and (3) restrictions on the acceleration of payment. Failure to comply with Code

Section 409A may result in the early taxation (plus interest) to the participant of deferred compensation

and the imposition of a 20% penalty on the participant on the deferred amounts included in the

participant’s income. We intend to structure awards under the Plan to be exempt from or comply with

Code Section 409A.

Awards Granted Under the Incentive Plan as Amended and Restated

The benefits that will be received under the Incentive Plan as Amended and Restated by particular

individuals or groups are not determinable at this time. Although not necessarily indicative of future grants

that may be made under the Incentive Plan as Amended and Restated , please see the “Grants of Plan-

Based Awards” table below with respect to awards of restricted stock units and performance units to

Named Executive Officers in 2024 .

Frequently Asked Questions

Why did I receive these proxy materials?

This proxy statement is furnished in connection with the solicitation of proxies by the Board for use at

2025 Annual Meeting of Stockholders of Oceaneering., to be held at 5775 N. Sam Houston Pkwy. W.,

Houston, Texas 77086 on Friday, May 9, 2025 at 11:00 A.M. prevailing Central Time , or any adjournment

or postponement thereof. The purposes of the meeting are set forth in the accompanying Notice of 2025

Annual Meeting of Stockholders and information about Oceaneering’s governance and executive

compensation is set forth elsewhere in this proxy statement. Please review these materials carefully

before casting your vote. We are asking that you vote on four proposals.

What Is “Notice And Access” And Why Does Oceaneering Use It?

We are making the proxy solicitation materials available to our stockholders electronically via the Internet

under the Notice and Access rules and regulations of the SEC. On or about March 28, 2025 , we will mail

to our stockholders the Notice in lieu of mailing a full set of proxy materials. Accordingly, our proxy

materials are first being made available to our stockholders on or about March 28, 2025 . The Notice

includes information on how to access and review the proxy materials and how to vote online. All

stockholders will have the ability to access the proxy materials on the Internet at www.proxyvote.com as

instructed in the Notice or request a printed set of the proxy materials. Instructions on how to access the

proxy materials on the Internet or to request a printed copy may be found in the Notice. In addition,

stockholders may request to receive proxy materials in printed form by mail or electronically by email on

an ongoing basis. Electronic delivery decreases costs, expedites distribution, and reduces our

environmental impact. We encourage stockholders to take advantage of the availability of the proxy

materials on the Internet at www.proxyvote.com to help reduce the environmental impact of the Annual

Meeting. Stockholders who received the Notice but would like to receive a printed copy of the proxy

materials in the mail should follow the instructions in the Notice for requesting such materials.

Additionally, we will furnish without charge to each person whose proxy is being solicited, upon

the written request of any such person, a copy of our Annual Report on Form 10-K for the fiscal

year ended December 31, 2024 (as amended by the 10-K/A filed on March 4, 2025), including the

financial statements. Such requests should be directed to the Corporate Secretary c/o

Oceaneering International, Inc., 5875 N. Sam Houston Pkwy. W., Suite 400, Houston, Texas 77086 .

Who is entitled to vote?

Only holders of record of shares of Oceaneering International, Inc. (“Oceaneering”) common stock, $0.25

par value per share (“Common Stock”) at the close of business on March 17, 2025 , the record date, will

be entitled to notice of, and to vote at, the meeting. As of that date, 101,071,473 shares of our Common

Stock were outstanding. Each of those outstanding shares is entitled to one vote at the meeting.

What are my voting options and what is the voting requirement for each of the

proposals?

At the Annual Meeting, stockholders will be asked to consider and act upon the following matters

discussed in this proxy statement. For Proposal 1, you may choose to vote “FOR” or “WITHHOLD.” For

Proposals 2, 3, and 4, you may choose to vote “FOR,” “AGAINST” or “ABSTAIN.” For Proposal 1, a

withhold vote will have no effect. For Proposals 2 and 4, abstentions will have the effect of a vote against

the proposal, while abstentions will have no effect on Proposal 3. Failure of a beneficial owner to provide

voting instructions to its broker or nominee with regard to Proposals 1, 2 or 4 will result in a “broker non-

vote” for such shares of Common Stock beneficially owned, which will have no impact on such proposal.

Table of Contents

Since Proposal 3 is a routine proposal that brokers can vote on absent specific instruction, no broker non-

votes are expected for such proposal.

Proposal		Recommendation of the Board	Vote Required
1	Election of Class III Directors : Roderick A. Larson, M. Kevin McEvoy, and Paul B. Murphy, Jr.	FOR each of the nominees	Per our Bylaws, each director nominee who receives a plurality of the votes cast (i.e., nominees receiving the highest number of “for” votes) will be elected. However, our Corporate Governance Guidelines require a director nominee to tender their resignation in an uncontested election if such nominee does not receive a “for” vote by a majority of the shares present in person or by proxy and entitled to vote and actually voting on the proposal.
2	Advisory Vote to Approve Executive Compensation	FOR	Affirmative vote of a majority of the shares of Common Stock present in person or by proxy and entitled to vote thereon.
3	Ratification of Appointment of Ernst & Young LLP as independent auditors of Oceaneering for the year ending December 31, 2025	FOR	Affirmative vote of a majority of the shares of Common Stock voted on this proposal at the meeting.
4	Approval of the Amended and Restated 2020 Incentive Plan	FOR	Affirmative vote of a majority of the shares of Common Stock present in person or by proxy and entitled to vote thereon.

How do I vote?

Your vote is important. You may vote in person at the meeting or by proxy. We recommend you vote by

proxy even if you plan to attend the meeting. You may always change your vote at the meeting if you are

a holder of record or have a proxy from the record holder. Giving us your proxy means that you authorize

us to vote your shares of Common Stock at the meeting in the manner you indicated on your proxy card.

You may also provide your proxy using the Internet or telephone procedures described on the proxy card.

If you give us your proxy but do not specify how to vote, we will vote your shares of Common Stock in

accordance with the recommendations of the Board.

Voting by Mail You may sign, date, and return your proxy card in the pre-addressed, postage-paid envelope provided. If you return your proxy card without indicating how you want to vote, the designated proxies will vote as set forth above. Voting by Telephone If you are a stockholder of record, you may vote by proxy by using the toll- free number listed on your proxy card. Voting via the Internet If you are a stockholder of record, you may vote by proxy by using the following Internet address: proxyvote.com. Voting at the Meeting Stockholders of record may also vote at the Annual Meeting. However, even if you plan to attend the Annual Meeting, we recommend that you also vote by proxy as described in this Proxy Statement, so that your votes will be counted if you do not participate in the meeting.

The telephone and Internet voting procedures are designed to verify your vote through the use of a

unique voter control number that is provided on each proxy card. The procedures also allow you to vote

Table of Contents

your shares and to confirm that your instructions have been properly recorded. Please see your proxy

card for specific instructions.

If you hold shares through a brokerage firm, bank, or other custodian, you may vote via the Internet or by

telephone only if the custodian offers that option.

What if I change my mind after I have voted?

If you are a stockholder of record, and you vote by proxy by mail, the Internet or telephone, you may later

revoke your proxy instructions by:

• sending a written statement to that effect to our Corporate Secretary c/o Oceaneering International,

Inc., 5875 N. Sam Houston Pkwy. W., Suite 400, Houston, Texas 77086 , the mailing address for the

executive offices of Oceaneering, provided that we receive the statement before the Annual

Meeting;

• submitting a signed proxy card with a date later than the date of the revoked proxy but prior to the

Annual Meeting;

• voting by proxy at a later time, but prior to the Annual Meeting, via the Internet or by telephone; or

• voting in person at the Annual Meeting.

If you have shares held through a brokerage firm, bank, or other custodian, and you vote by proxy, you

may later revoke your proxy instructions only by informing the custodian in accordance with any

procedures it sets forth.

Will my shares be voted if I do not provide my proxy?

It depends on whether you hold your shares of Common Stock in your own name as a registered

stockholder or in the name of a bank or brokerage firm as a beneficial owner. If you hold your shares of

Common Stock directly in your own name as a registered stockholder, then they will not be voted unless

you provide a proxy or vote in person at the meeting.

If your shares of Common Stock are held in the name of a broker, bank or other nominee, such broker or

other nominee can vote your shares on any proposal that is considered a “routine” matter as determined

by the NYSE. Of the proposals, only Proposal 3 is considered “routine” and, accordingly, only with

respect to Proposal 3 can a broker or other nominee exercise voting discretion absent specific instruction

from the beneficial owner. Since Proposal 3 is a routine Proposal that brokers can vote on absent specific

instruction, no broker non-votes are expected for such proposal.

For all other proposals (specifically, Proposals 1, 2 and 4), since the NYSE precludes brokers from

exercising voting discretion on these “non-routine” proposals without specific instructions from the

beneficial owner as to how to vote, any brokers holding shares of Common Stock must vote for those

proposals according to specific instructions they receive (if any) from the beneficial owners of those

shares of Common Stock. If you do not instruct your broker how to vote with respect to Proposal 1,

Proposal 2, or Proposal 4, your broker will not vote for you with respect to those proposals.

Failure of a beneficial owner to provide voting instructions with regard to Proposals 1, 2 or 4 will result in

a “broker non-vote” for such shares of Common Stock beneficially owned. Broker non-votes will have no

impact on Proposals 1, 2 or 4.

Can I vote my shares that are held in the Oceaneering Retirement Investment Plan?

If you participate in the Oceaneering Retirement Investment Plan (“Plan”), you have the right to direct

Fidelity Management Trust Company, the trustee of the Plan (the “Trustee”), to vote your shares of

Oceaneering common stock held in your separate Plan account.

You may instruct the Trustee as to how to vote the shares of Oceaneering common stock in your Plan

account via telephone or the Internet. If you wish to provide your instructions via telephone, please call

1-800-690-6903 and follow the prompts. If you wish to provide your instructions via the Internet, log on to

www.proxyvote.com and follow the instructions provided.

To allow sufficient time for voting by the Trustee of the Plan, your voting instructions must be received no

later than 11:59 p.m., Central Time, on May 1, 2025. Any shares of Oceaneering common stock held in

Table of Contents

the Plan for which the Trustee does not receive timely participant directions will be voted by the Trustee in

the same proportion as the shares for which the Trustee receives timely voting instructions from

participants within the Plan.

How do I attend the Annual Meeting in person?

Registered stockholders will be asked to present a valid government-issued photo identification. If your

shares are held in the name of your broker, bank, or other nominee, you must bring to the meeting a valid

government-issued photo identification and an account statement or letter (and a legal proxy if you wish

to vote your shares) from the nominee indicating that you beneficially owned the shares on the record

date for voting.

What constitutes a quorum of stockholders?

We must have a quorum to conduct the meeting. The requirement for a quorum at the meeting is the

presence in person or by proxy of holders of a majority of the outstanding shares of Common Stock.

Broker non-votes, abstentions and withhold votes count for purposes of determining a quorum.

Who conducts the proxy solicitation and how much will it cost?

We began mailing this proxy statement and the accompanying proxy card to stockholders on or about

March 28, 2025 . The proxy statement and proxy card are being furnished at the direction of the Board.

We will pay all solicitation costs, which includes $30,000 for the fee of Innisfree M&A Incorporated who

will help us solicit proxies. We will reimburse brokerage firms, nominees, fiduciaries, custodians, and

other agents for their expenses in distributing proxy materials to the holders of Common Stock. In

addition, certain of our directors, officers and employees may solicit proxies by telephone and personal

contact. Directors, officers, and other employees will not receive additional compensation for these

services.

What is householding?

As permitted by the SEC rules, only one copy of this proxy statement is being delivered to stockholders

residing at the same address, unless the stockholders have notified the Company of their desires to

receive multiple copies of the proxy statement.

This is known as “householding.” This procedure reduces the environmental impact of our annual

meetings and reduces the Company’s printing and mailing costs. Upon oral or written request, we will

promptly deliver a separate copy of the proxy statement to any stockholder residing at an address to

which only one copy was mailed. You may direct requests for additional copies for the current year or

future years to our Investor Relations team at the following physical address, phone number or email

You may direct requests for additional copies of the proxy statement for the current year or future years to

How do I submit a stockholder proposal for action at the 2026 annual meeting of

stockholders?

Any stockholder who wishes to have a qualified proposal considered for inclusion in our proxy statement

for our 2026 Annual Meeting of Stockholders must send notice of the proposal to our Corporate Secretary

at our principal executive offices, 5875 N. Sam Houston Pkwy. W., Suite 400, Houston, Texas 77086 , so

that such notice is received not later than November 28, 2025 . If you submit such a proposal, you must

provide your name, address, the number of shares of Common Stock held of record or beneficially, the

date or dates on which you acquired those shares and documentary support for any claim of beneficial

ownership.

In addition, any stockholder who intends to submit a proposal for consideration at our 2026 Annual

Meeting of Stockholders, regardless of whether the proposal is submitted for inclusion in our proxy

statement for that meeting, or who intends to submit nominees for election as directors at that meeting,

must notify our Corporate Secretary. Under our Bylaws, such notice must:

• be received at our executive offices not earlier than November 10, 2025 , and not later than close of

business on February 8, 2026 ; and

• satisfy the requirements that our Bylaws specify.

A copy of the pertinent Bylaw provisions can be obtained from our Corporate Secretary on written

request.

How do I nominate a director or present other items for action at the 2026 annual meeting

of stockholders?

The Nominating, Corporate Governance & Sustainability Committee will consider nominees

recommended by stockholders in accordance with our Bylaws. A stockholder who wishes to recommend

a nominee for director should comply with the procedures specified in our Bylaws, as well as applicable

securities laws and regulations of the NYSE. The Nominating, Corporate Governance & Sustainability

Committee will consider all candidates identified through the processes described above, whether

identified by the committee or by a stockholder, and will evaluate each of them on the same basis.

As to each person a stockholder proposes to nominate for election as a director, our Bylaws provide that

the nomination notice must:

• include the name, age, business address, residence address (if known) and principal occupation or

employment of that person, the number of shares of Common Stock beneficially owned or owned of

record by that person and any other information relating to that person that is required to be

disclosed under Section 14 of the Securities Exchange Act of 1934, as amended (the “Exchange

Act”), and the related SEC rules and regulations; and

the purposes of this Plan. Any decision of the Committee in the interpretation and administration of this

Plan shall lie within its sole and absolute discretion and shall be final, conclusive and binding on all

parties concerned. The Board shall have the same powers as the Committee with respect to Awards to

Nonemployee Directors.

(2) Indemnity. No member of the Board or the Committee or officer of the Company to whom the

Committee has delegated authority in accordance with the provisions of paragraph 7 of this Plan shall

Committee or by any officer of the Company in connection with the performance of any duties under

this Plan, except for their own willful misconduct or as expressly provided by statute.

off, combination, or exchange of shares), the terms of outstanding Options and SARs may not be

amended to (i) reduce the exercise price of outstanding Options or SARs or (ii) cancel outstanding

Options or SARs in exchange for cash, other Awards or Options or SARs with an exercise price that is

Company its authority to make Awards to any officer of the Company. Any such delegation hereunder shall

only be made to the extent permitted by applicable law.

Awards . Except as otherwise provided in paragraph 9 hereof pertaining to Awards to Nonemployee

Directors, the Committee shall determine the type or types of Awards to be made under this Plan and shall

be embodied in an Award Agreement in such form as the Committee determines, which shall contain such

terms, conditions and limitations as shall be determined by the Committee in its sole discretion, including

any treatment upon a Change of Control, and shall be issued for and on behalf of the Company. Awards

may consist of those listed in this paragraph 8 and may be granted singly, in combination or in tandem.

Awards may also be made in combination or in tandem with, in replacement of, or as alternatives to, grants

or rights under this Plan or any other plan of the Company or any of its Subsidiaries, including this Plan of

any acquired entity; provided that, except as contemplated in paragraph 15 hereof, no Option or SAR may

conditions established by the Committee, which may include, but are not limited to, continuous service with

the Company and its Subsidiaries, achievement of specific business objectives, increases in specified

indices, attainment of specified growth rates and other measurements of performance. Upon the termination

of employment by a Participant who is an Employee, any unexercised, deferred, unvested or unpaid Awards

shall be treated as set forth in the applicable Award Agreement.

may be purchased upon the exercise of an Option shall be not less than the Fair Market Value of the

Common Stock on the date of grant. The term of an Option shall not exceed ten years from the date of

grant. Subject to the foregoing provisions, the terms, conditions and limitations applicable to any

Options awarded pursuant to this Plan, including the term of any Options and the date or dates upon

which such Options become exercisable, shall be determined by the Committee.

terms, conditions and limitations applicable to any SARs awarded pursuant to this Plan, including the

term of any SARs and the date or dates upon which such SARs become exercisable, shall be

designate that the Award will be paid (i) only in cash, (ii) only in Common Stock, or (iii) in such other

form or combination of forms as the Committee may elect or permit at the time of exercise.

applicable to any Stock Awards granted pursuant to this Plan shall be determined by the Committee,

subject to the limitations specified below.

(4) Cash Award. An Award may be in the form of a Cash Award. The terms, conditions and limitations

applicable to any Cash Awards granted pursuant to this Plan shall be determined by the Committee.

(5) Performance Award. Without limiting the type or number of Awards that may be made under the other

provisions of this Plan, an Award may be in the form of a Performance Award. The amount of cash or

shares of Common Stock payable or issuable or vested pursuant to Performance Awards may be

adjusted upward or downward, either on a formula or discretionary basis or any combination, as the

Committee determines in its discretion. Subject to the foregoing provisions, the terms, conditions and

limitations applicable to any Performance Awards made pursuant to this Plan shall be determined by

the Committee.

(6) Minimum Vesting. Any Award (other than a Cash Award) shall have a minimum vesting period or

Restriction Period, as applicable, of one year from the date of grant, provided that (i) the Committee

may provide for earlier vesting or termination of the Restriction Period following a Change of Control or

upon termination of a Participant’s employment or service by reason of death, disability or retirement

and (ii) Awards with respect to up to 5% of the shares of Common Stock authorized for grant pursuant

to this Plan may have a vesting period or Restriction Period, as applicable, of less than one year.

Awards to Nonemployee Directors. Subject to the limitations set forth in paragraph 5(c) hereof, the Board

may grant a Nonemployee Director of the Company one or more Awards, other than in the form of Incentive

Options, and establish the terms thereof in accordance with paragraph 8 and consistent with the provisions

therein for the granting of Awards to Employees by the Committee. Any such Award shall be subject to the

applicable terms, conditions and limitations set forth in this Plan and the applicable Award Agreement. Upon

the termination of service by a Participant who is a Nonemployee Director, any unexercised, deferred,

unvested or unpaid Awards shall be treated as set forth in the applicable Award Agreement.

Award Payment; Dividends and Dividend Equivalents.

(1) General. As specified in the applicable Award Agreements, payment of Awards may be made in the

form of cash or Common Stock, or a combination thereof, and may include such restrictions as the

Committee shall determine, including, in the case of Common Stock, restrictions on transfer and

forfeiture provisions. If payment of an Award is made in the form of Restricted Stock, the right to receive

such shares shall be evidenced by book-entry registration or in such other manner as the Committee

may determine from time to time. Any statement of ownership evidencing such Restricted Stock shall

contain appropriate legends and restrictions that describe the terms and conditions of the restrictions

applicable thereto.

A-6

Table of Contents

(2) Dividends, Dividend Equivalents and Interest. Rights to dividends or Dividend Equivalents may be

extended to and made part of any Stock Award, subject to such terms, conditions and restrictions as the

Committee may establish; provided that any dividends or Dividend Equivalents payable in connection

with any Stock Award (as provided in the applicable Award Agreement) may accrue but will not, in any

event, be payable until the expiration of the vesting period or Restriction Period, as applicable, of the

underlying Stock Award. The Committee may also establish rules and procedures for the crediting of

interest on deferred cash payments, dividends or Dividend Equivalents. Dividends and/or Dividend

Equivalents shall not be made part of any Options or SARs.

Stock Option Exercise. The price at which shares of Common Stock may be purchased under an Option

shall be paid in full at the time of exercise in cash or, if set forth in the Award Agreement and elected by the

Participant, the Participant may purchase such shares by means of the Company withholding shares of

Common Stock otherwise deliverable on exercise of the Award or tendering Common Stock or surrendering

another Award, including Restricted Stock, valued at Fair Market Value on the date of exercise, or any

combination thereof. The Committee, in its sole discretion, shall determine acceptable methods for

Participants to tender Common Stock or other Awards. The Committee may provide for procedures to

permit the exercise or purchase of such Awards by use of the proceeds to be received from the sale of

Common Stock issuable pursuant to an Award (including cashless exercise procedures approved by the

Committee involving a broker or dealer approved by the Committee). Unless otherwise provided in the

applicable Award Agreement, in the event shares of Restricted Stock are tendered as consideration for the

exercise of an Option, a number of the shares issued upon the exercise of the Option, equal to the number

of shares of Restricted Stock used as consideration therefore, shall be subject to the same restrictions as

the Restricted Stock so submitted as well as any additional restrictions that may be imposed by the

Committee. The Committee may adopt additional rules and procedures regarding the exercise of Options

from time to time, provided that such rules and procedures are not inconsistent with the provisions of this

paragraph 11.

Taxes . The Company shall have the right to deduct applicable taxes from any Award payment and withhold

an appropriate amount of cash or number of shares of Common Stock or a combination thereof for payment

of taxes required by law or to take such other action as may be necessary in the opinion of the Company to

satisfy all obligations for withholding of such taxes. The Committee may also permit withholding to be

satisfied by (i) the transfer to the Company of shares of Common Stock theretofore owned by the holder of

the Award or (ii) withholding from the shares of Common Stock otherwise deliverable under the Award, in

either case with respect to which withholding is required, up to the maximum tax rate applicable to the

Participant. If shares of Common Stock are used to satisfy tax withholding, such shares shall be valued

based on the Fair Market Value when the tax withholding is required to be made.

Amendment, Modification, Suspension or Termination. The Board may amend, modify, suspend or

terminate this Plan (and the Committee may amend or modify an Award Agreement) for the purpose of

meeting or addressing any changes in legal requirements or for any other purpose permitted by applicable

law, except that (i) no amendment or alteration that would materially adversely affect the rights of any

Participant under any Award previously granted to such Participant shall be made without the consent of

such Participant and (ii) no amendment or alteration shall be effective prior to its approval by the

stockholders of the Company to the extent stockholder approval is otherwise required by applicable legal

requirements or the requirements of the securities exchange on which the Company’s stock is listed,

including any amendment that expands the types of Awards available under this Plan, materially increases

the number of shares of Common Stock available for Awards under this Plan, materially expands the

classes of persons eligible for Awards under this Plan, materially extends the term of this Plan, materially

changes the method of determining the Exercise Price of Options or strike price of SARs, deletes or limits

any provisions of this Plan that prohibit the repricing of Options or SARs. Notwithstanding any provision in

this Plan to the contrary, this Plan shall not be amended or terminated in such manner that would cause this

Plan or any amounts or benefits payable hereunder to fail to comply with or be exempt from Section 409A,

and any such amendment or termination that may reasonably be expected to result in such failure shall be

of no force or effect.

Assignability. Unless otherwise determined by the Committee (or the Board, in the case of Awards to

Nonemployee Directors) and provided in the Award Agreement, no Award may be assigned or otherwise

transferred except by will or the laws of descent and distribution or pursuant to a domestic relations order in

a form acceptable to the plan administrator. Any attempted assignment of an Award or any other benefit

under this Plan in violation of this paragraph 14 shall be null and void.

Adjustments.

(1) The existence of outstanding Awards shall not affect in any manner the right or power of the Company

or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or

other changes in the capital stock of the Company or its business or any merger or consolidation of the

Company, or any issue of bonds, debentures, preferred or prior preference stock (whether or not such

issue is prior to, on a parity with or junior to the Common Stock) or the dissolution or liquidation of the

Company, or any sale or transfer of all or any part of its assets or business, or any other corporate act

or proceeding of any kind, whether or not of a character similar to that of the acts or proceedings

enumerated above.

(2) In the event of any subdivision or consolidation of outstanding shares of Common Stock, declaration of

a dividend payable in shares of Common Stock or other stock split, then (i) the number of shares of

Common Stock reserved under this Plan, (ii) the number of shares of Common Stock available under

this Plan for Incentive Options and Stock Awards, (iii) the number of shares of Common Stock covered

by outstanding Awards in the form of Common Stock or units denominated in Common Stock, (iv) the

exercise or other price in respect of such Awards, (v) the Stock-Based Award Limitations, and (vi) the

appropriate Fair Market Value and other price determinations for such Awards shall each be

proportionately adjusted by the Committee to reflect such transaction. In the event of any other

recapitalization or capital reorganization of the Company, any consolidation or merger of the Company

with another corporation or entity, the adoption by the Company of any plan of exchange affecting the

Common Stock or any distribution to holders of Common Stock of securities or property (other than

normal cash dividends or dividends payable in Common Stock), the Committee shall make appropriate

adjustments to (1) the number of shares of Common Stock covered by Awards in the form of Common

Stock or units denominated in Common Stock, (2) the exercise or other price in respect of such Awards,

(3) the appropriate Fair Market Value and other price determinations for such Awards, (4) the number of

shares of Common Stock available under this Plan for Incentive Options and Stock Awards, and (5) the

Stock-Based Award Limitations to give effect to such transaction; provided that such adjustments shall

only be such as are necessary to maintain the proportionate interest of the holders of the Awards and

preserve, without exceeding, the value of such Awards.

(3) In the event of a corporate merger, consolidation, acquisition of property or stock, separation,

reorganization or liquidation, the Committee may make such adjustments to Awards or other provisions

for the disposition of Awards as it deems equitable, and shall be authorized, in its discretion, to (i)

provide for the substitution of a new Award or other arrangement (which, if applicable, may be

exercisable for such property or stock as the Committee determines) for an Award or the assumption of

the Award (and for awards not granted under this Plan), regardless of whether in a transaction to which

Section 424(a) of the Code applies, (ii) provide, prior to the transaction, for the acceleration of the

vesting and exercisability of, or lapse of restrictions with respect to, the Award and, if the transaction is

a cash merger, provide for the termination of any portion of the Award that remains unexercised at the

time of such transaction, (iii) provide for the acceleration of the vesting and exercisability of an Award

and the cancellation thereof in exchange for such payment as the Committee, in its sole discretion,

determines is a reasonable approximation of the value thereof, (iv) cancel any Awards and direct the

Company to deliver to the Participants who are the holders of such Awards cash in an amount that the

Committee shall determine in its sole discretion is equal to the Fair Market Value of such Awards as of

the date of such event, which, in the case of any Option, shall be the amount equal to the excess of the

Fair Market Value of a share as of such date over the per-share exercise price for such Option (for the

avoidance of doubt, if such Fair Market Value is less than such exercise price, the Option may be

canceled for no consideration), or (v) cancel Awards that are Options and give the Participants who are

the holders of such Awards notice and opportunity to exercise prior to such cancellation.

(4) No adjustment authorized by this paragraph 15 shall be made in such manner that would result in this

Plan or any amounts or benefits payable hereunder to fail to comply with or be exempt from Section

409A, and any such adjustment that may reasonably be expected to result in such failure shall be of no

force or effect.

Restrictions. No Common Stock or other form of payment shall be issued or made with respect to any

Award unless the Company shall be satisfied based on the advice of its counsel that such issuance or other

payment will be in compliance with all applicable federal and state securities laws. Certificates evidencing

shares of Common Stock delivered under this Plan (to the extent that such shares are so evidenced) may

be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under

the rules, regulations and other requirements of the Securities and Exchange Commission, any securities

exchange or transaction reporting system upon which the Common Stock is then listed or to which it is

admitted for quotation and any applicable federal or state securities law. The Committee may cause a

legend or legends to be placed upon such certificates (if any) to make appropriate reference to such

restrictions.

Unfunded Plan. This Plan is unfunded. Although bookkeeping accounts may be established with respect to

Participants who are entitled to cash, Common Stock or rights thereto under this Plan, any such accounts

shall be used merely as a bookkeeping convenience. The Company shall not be required to segregate any

assets that may at any time be represented by cash, Common Stock or rights thereto, nor shall this Plan be

construed as providing for such segregation, nor shall the Company, the Board or the Committee be

deemed to be a trustee of any cash, Common Stock or rights thereto to be granted under this Plan. Any

liability or obligation of the Company to any Participant with respect to an Award of cash, Common Stock or

rights thereto under this Plan shall be based solely upon any contractual obligations that may be created by

this Plan and any Award Agreement, and no such liability or obligation of the Company shall be deemed to

be secured by any pledge or other encumbrance on any property of the Company. None of the Company,

the Board or the Committee shall be required to give any security or bond for the performance of any

obligation that may be created by this Plan.

Section 409A .

(1) Notwithstanding anything in this Plan to the contrary, if any Plan provision or Award under this Plan

would result in the imposition of an additional tax under Section 409A, that Plan provision or Award will

be reformed to avoid imposition of the additional tax, including that any Award subject to Section 409A

held by a specified employee that is settled upon termination of employment (for reasons other than

death) shall be delayed in payment until the expiration of six months, and no action taken to comply

with Section 409A shall be deemed to adversely affect the Participant’s rights to an Award. Awards

made under this Plan are intended to comply with or be exempt from Section 409A, and ambiguous

provisions hereof, if any, shall be construed and interpreted in a manner consistent with such intent. No

payment, benefit or consideration shall be substituted for an Award if such action would result in the

imposition of taxes under Section 409A.

(2) Unless the Committee provides otherwise in an Award Agreement, each Award of Restricted Stock

Units or Cash Award (or portion thereof if the Award is subject to a vesting schedule) shall be settled no

later than the 15th day of the third month after the end of the first calendar year in which the Award (or

such portion thereof) is no longer subject to a “substantial risk of forfeiture” within the meaning of

Section 409A. If the Committee determines that an Award of Restricted Stock Units or a Cash Award is

intended to be subject to Section 409A, the applicable Award Agreement shall include terms that are

designed to satisfy the requirements of Section 409A.

(3) If the Participant is identified by the Company as a “specified employee” within the meaning of Section

409A(a)(2)(B)(i) of the Code on the date on which the Participant has a “separation from service” (other

than due to death) within the meaning of Treasury Regulation §1.409A-1(h), any Award payable or

settled on account of a separation from service that is deferred compensation subject to Section 409A

shall be paid or settled on the earliest of (1) the first business day following the expiration of six months

from the Participant’s separation from service, (2) the date of the Participant’s death, or (3) such earlier

date as complies with the requirements of Section 409A.

Governing Law. This Plan and all determinations made and actions taken pursuant hereto, to the extent not

otherwise governed by mandatory provisions of the Code or the securities laws of the United States, shall

be governed by and construed in accordance with the laws of the State of Delaware.

Right to Continued Service or Employment. Nothing in this Plan or an Award Agreement shall interfere with

or limit in any way the right of the Company or any of its Subsidiaries to terminate any Participant’s

employment or other service relationship with the Company or its Subsidiaries at any time, nor confer upon

any Participant any right to continue in the capacity in which they are employed or otherwise serves the

Company or its Subsidiaries.

Clawback Right. Notwithstanding any other provisions in this Plan, any Award shall be subject to recovery

or clawback by the Company pursuant to any applicable law regulation or stock exchange listing

requirement and under any clawback policy adopted by the Company whether before or after the date of

grant of the Award.

Usage. Words used in this Plan in the singular shall include the plural and vice versa, and words of one

gender shall be construed to include the other gender and the neuter, in each case as the context requires.

A-9

Table of Contents

Headings. The headings in this Plan are inserted for convenience of reference only and shall not affect the

meaning or interpretation of this Plan.

Effectiveness. This Plan, as approved by the Board on February 21, 2025 , shall be effective as of the

Effective Date. This Plan shall continue in effect for a term of ten years commencing on the Effective Date,

unless earlier terminated by action of the Board, and no further Awards may be granted under this Plan after

the tenth anniversary of the Effective Date or, if earlier, termination by action of the Board, except as to

Awards then outstanding under this Plan. Such outstanding Awards shall remain in effect until they have

been exercised or terminated, or have expired.

Notwithstanding the foregoing, the adoption of this Plan is expressly conditioned upon the approval by the holders

of a majority of shares of Common Stock present, or represented, and entitled to vote at the Company’s 2025

annual meeting of stockholders scheduled to be held on May 9, 2025 , or any adjournment or postponement thereof,

as the case may be. If the stockholders of the Company should fail to so approve this Plan, this Plan shall not be of

any force or effect and the Plan as in effect prior to its amendment and restatement shall continue in force and

effect.
