Forward-Looking Statements

The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking statements to encourage companies to provide prospective information to investors. This Proxy Statement includes forward-looking statements that reflect our current expectations and projections about our future results, performance and prospects. Forward-looking statements include all statements that are not historical in nature or are not current facts. When used in this Proxy Statement, the words “believe,” “expect,” “plan,” “intend,” “anticipate,” “estimate,” “predict,” “potential,” “continue,” “may,” “might,” “should,” “could,” “will” or the negative of these terms or similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on our current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. These forward-looking statements are subject to a number of risks, uncertainties, assumptions and other factors that could cause our actual results, performance and prospects to differ materially from those expressed in, or implied by, these forward-looking statements, including, but are not limited to, risks and uncertainties listed in our filings with the U.S. Securities and Exchange Commission (“SEC”), including our Current Reports on Form 8-K that we file from time to time, Quarterly Reports on Form 10-Q and Annual Reports on Form 10-K. Readers are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date hereof. We undertake no obligation to publicly update or revise any forward-looking statements after the date they are made, whether as a result of new information, future events or otherwise, except as required by law.

GOVERNANCE HIGHLIGHTS

Our commitment to high ethical standards is reflected in the governance practices our Board follows.

Independence	•  Seven of our eight current directors are independent.
	•  Each of our Audit Committee, Compensation Committee, and Nominating and Corporate Governance Committee (together, the “Committees”) is composed exclusively of independent directors.
Executive Sessions	•  The independent directors regularly meet in private without management. •  Our Board Committees meet in executive session at each regularly scheduled meeting, no fewer than four times per year for our Audit Committee and Compensation Committee.
Board Oversight of Risk Management	•  Our Board reviews our systematic approach to identifying and assessing risks faced by the Company. •  Our Board reviews our approach to environmental, social and governance matters. •  The Audit Committee reviews our overall enterprise risk management policies and practices, financial risk exposures and the delegation of risk oversight responsibilities to other Board Committees. •  Our Audit Committee meets regularly with our information technology director to discuss enterprise resource planning and cybersecurity risk matters. •  The Audit Committee meets with our independent auditor without management present at each quarterly meeting of the Board and its Committees.
Board Practices	•  Our Board annually reviews its effectiveness as a group. •  Nomination policies are adjusted as needed to ensure that our Board as a whole continues to reflect the appropriate mix of skills and experience.
Accountability	•  Our Corporate Governance Guidelines provide that any nominee for director who receives a greater number of “withheld” votes than “for” votes in an uncontested election shall tender their resignation to the Chairman of the Board. Then the Chairman of the Board, considering the best interests of the Company and any current or foreseeable factors or circumstances related to this director, shall recommend to the Board whether or not to accept the resignation, and if so, under what conditions. Within ninety days of the stockholder vote, the Board shall decide whether or not to accept the director’s tendered resignation, and then the Company will make a public announcement of the Board’s decision.
Prohibition on Hedging; Pledging of KLXE Shares	•  To avoid conflicts of interest that could undermine the goals of our share ownership policy and the focus on sustainable long-term growth, the Company prohibits directors and employees from entering into transactions involving short sales of our securities or put or call options based on our securities, except for options granted under KLXE compensation programs. In addition, directors and NEOs are generally prohibited from holding Company shares in a margin account or pledging Company shares as collateral for a loan.

PROPOSAL 1: AMENDMENT TO THE COMPANY’S AMENDED AND

RESTATED CERTIFICATE OF INCORPORATION TO DECLASSIFY THE BOARD

Background

The Board currently consists of eight directors divided into three classes (Class I, Class II and Class III), and directors in each class are elected to serve three-year staggered terms that expire in successive years. The Board has unanimously approved the Declassification Amendment, subject to stockholder approval. The Board has unanimously determined that the Declassification Amendment is advisable and in the best interests of the Company and our stockholders, and, in accordance with the General Corporation Law of the State of Delaware (“DGCL”), hereby seeks approval of the Declassification Amendment by our stockholders.

If this proposal is approved, Article V of our Amended and Restated Certificate of Incorporation would be amended to provide for the phased elimination of the classified structure of the Board over three annual meetings, beginning with this 2024 Annual Meeting. If this proposal is approved, the Class III directors who are elected at this 2024 Annual Meeting shall be elected for a one-year term ending at the 2025 Annual Meeting of Stockholders. The Class I and Class II directors who are elected at the 2025 Annual Meeting of Stockholders shall be elected for a one-year term ending at the 2026 Annual Meeting of Stockholders. Commencing with the election of directors at the 2026 Annual Meeting of Stockholders and for each annual meeting of stockholders thereafter, the Board shall no longer be classified and each director elected at an annual meeting of stockholders shall hold office until the next succeeding annual meeting of stockholders and until such director’s successor has been duly elected and qualified, or until such director’s earlier death, resignation or removal.

As discussed in connection with Proposal 2, if the Declassification Amendment is approved by our stockholders, the directors who are elected at this Annual Meeting will be elected to one-year terms. However, the Declassification Amendment would not change the terms of the directors whose terms do not expire at this 2024 Annual Meeting. If this proposal is approved by our stockholders by the requisite vote at this 2024 Annual Meeting, then the amendment will become effective upon the filing of a certificate of amendment setting forth the Declassification Amendment (the “Certificate of Amendment”) with the office of the Secretary of State of the State of Delaware. If this proposal is approved by our stockholders, we intend to file the Certificate of Amendment during this 2024 Annual Meeting, immediately after the requisite vote for this Proposal 1 is obtained and prior to the vote on the election of directors.

This proposal, if approved, would not change the Board’s authority to change the present number of directors and to fill any vacancies or newly created directorships. However, this proposal provides that any director appointed to fill newly created Board seats or vacancies would hold office for a term expiring at the next annual meeting of stockholders following such director’s appointment.

In addition, because our Board is classified, our Amended and Restated Certificate of Incorporation currently provides that directors may be removed only for cause, consistent with Delaware law, and requires the vote of 66 2/3% of the total voting power of the outstanding shares of capital stock entitled to vote shall be required to remove a director. This proposal provides that all directors may be removed with or without cause, and requires only a majority of the voting power of the then-outstanding voting stock of the Company shall be required to remove a director.

Proposed Declassification Amendment

The Board is asking our stockholders to approve the amendment to Article V of our Amended and Restated Certificate of Incorporation. The text of the Declassification Amendment is attached hereto as Appendix B, with additions marked with bold, underlined text and deletions indicated by strike-out text.

5

Reasons for the Declassification Amendment

This proposal is a result of the Board’s ongoing review of the Company’s corporate governance policies. A classified board structure can be viewed as diminishing a board’s accountability to stockholders because such structure does not enable stockholders to express a view on each director’s performance by means of an annual vote. Annual voting allows stockholders to express their views on the individual performance of each director and on the entire board of directors more frequently than with a classified board structure, which provides stockholders a more active role in shaping and implementing corporate governance policies. The Board believes that approval of an accelerated declassification of the Board will further enhance stockholder input, feedback and engagement through the annual meeting of stockholders process.

The Board has also considered the fact that an activist stockholder (or group of stockholders) could gain control of the Company by acquiring or obtaining enough shares to replace the entire Board with its own nominees at a single annual meeting of stockholders, which could result in radical changes to the way the Company is operated.

In view of these considerations, the Board has unanimously determined that it is in the best interests of the Company and its stockholders to further adopt best-in-class corporate governance practices and amend our Amended and Restated Certificate of Incorporation to eliminate the Company’s classified board structure and provide for the annual election of directors. The Board decided to adhere to market’s best practice in corporate governance by having all directors seeking election or re-election every year.

Effectiveness of the Declassification Amendment

If the Declassification Amendment is approved by our stockholders, the Declassification Amendment will become effective upon the filing of the Certificate of Amendment with the Delaware Secretary of State, which filing is expected to occur as soon as possible following stockholder approval of the Declassification Amendment during the 2024 Annual Meeting and prior to the election of directors at the 2024 Annual Meeting.

If the Declassification Amendment is not approved by our stockholders, the Amended and Restated Certificate of Incorporation will not be amended, the Board will remain classified as set forth in the Amended and Restated Certificate of Incorporation, and the Class III directors elected at this 2024 Annual Meeting will serve a three-year term expiring at the 2027 Annual Meeting of Stockholders.

Required Vote of Stockholders

Approval of the Declassification Amendment requires the affirmative vote of 66 2/3% in voting power of the outstanding voting stock of the Company, voting together as a single class. As a result, abstentions and broker non-votes will have the same effect as a vote “AGAINST” this proposal.

This Proposal 1 is separate from, and is not conditioned on, the approval of Proposal 5 (the Bylaw Supermajority Amendment) or Proposal 6 (the Charter Supermajority Amendment). Your votes on Proposals 5 and 6 do not affect your vote on Proposal 1. You can vote FOR, AGAINST or ABSTAIN from voting on any of these proposals.

THE BOARD RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE PROPOSED AMENDMENT TO THE COMPANY’S AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO DECLASSIFY THE BOARD.

PROPOSAL 2: ELECTION OF DIRECTORS

We are seeking your support in electing the candidates that we have nominated to serve on our Board. We believe that these nominees have qualifications consistent with our position as a leading independent provider of completion, intervention, production and drilling services to the major onshore oil and gas producing regions of the United States. We also believe that these nominees have the experience and perspective to guide the Company as we continue to compete, and to innovate and adjust to rapidly changing technologies, business cycles and competition.

As of the date of mailing, we have eight members on our Board. Pursuant to the Company’s Amended and Restated Certificate of Incorporation, the Board is divided into three classes, each as nearly equal in number as possible, so that each director will serve for three years, with one class of directors being elected each year. The directors designated as Class I directors have terms expiring at the 2025 Annual Meeting of Stockholders, the directors designated as Class II directors have terms expiring at the 2026 Annual Meeting of Stockholders and the directors designated as Class III directors have terms expiring at the 2024 Annual Meeting of Stockholders.

The Board has nominated the following persons for election as Class III directors to serve until the 2027 Annual Meeting of Stockholders (or until the 2025 Annual Meeting of Stockholders if Proposal 1 is approved and the Declassification Amendment is filed and becomes effective as described herein) and until their successors have been duly elected and qualified, or until their earlier death, resignation or removal:

Thomas P. McCaffrey

Corbin J. Robertson, Jr.

The persons named in the attached proxy intend to vote each share as to which a proxy has been properly executed and returned or submitted over the telephone or on the Internet and not revoked in favor of the election as directors of the nominees named above, who are now directors of the Company, unless authority to vote for the election of such nominee is withheld by marking the proxy to that effect. The attached proxy cannot be voted for a greater number of persons than two.

The director nominees have consented to being named as a nominee in this Proxy Statement and have indicated a willingness to serve if elected. We have no reason to believe that the director nominees will be unable or unwilling to serve on the Board if elected. However, if the nominees should become unable or unwilling to serve for any reason, proxies may be voted for another person nominated as a substitute by the Board. Stockholders may not cumulate their votes in the election of our directors.

Set forth below under “Board of Directors” is background information with respect to our director nominees, as well as certain information regarding their individual experience, qualifications, attributes and skills that led the Board to conclude that they should serve as directors. There are no family relationships among any of our directors or executive officers. Please see “Share Ownership Information—Security Ownership of Certain Beneficial Owners and Management” for information regarding our current directors’ and director nominees’ holdings of equity securities of the Company.

Required Vote of Stockholders

To be elected to the Board, a nominee must receive a plurality of the voting power of the shares entitled to vote on the election of directors and present in person or by proxy at the meeting, which means a nominee will be elected in an uncontested election if he or she receives at least one vote “FOR” such nominee. Nevertheless, if a nominee receives a number of “WITHHOLD” votes that equals or exceeds the number of “FOR” votes, that nominee must submit such director’s offer of resignation to the Chairman of the Board. See “Plurality Plus Majority Voting for Directors” below.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE ELECTION OF THE DIRECTOR NOMINEES.

CORPORATE GOVERNANCE

As previously discussed under “Proposal 2: Election of Directors,” the Board currently has eight members. The following table identifies the current members of the Board, the standing committees of the Board on which they serve and the chairman of each committee as of the date of this Proxy Statement.

Name of Director	Audit Committee			Compensation Committee			Nominating and Corporate Governance Committee
Christopher J. Baker

** Committee Chairman

+ Independent

After reviewing all relationships each director has with the Company, including the nature and extent of any business relationships between the Company and such person, the Board has affirmatively determined that each of Messrs. Collins, Eliassen, McCaffrey, Robertson, Skindlo and Whates and Ms. Hunter has no material relationships with the Company and is “independent” under the applicable rules and regulations of the SEC and the Nasdaq Global Select Market (“Nasdaq”). When determining whether to consider Mr. McCaffrey as an independent director, the Board also considered Mr. McCaffrey’s previous experience as President, Chief Executive Officer and Chief Financial Officer of KLXE from April 30, 2020 until the completion of the QES Merger in July 2020, and his experience as Senior Vice President and Chief Financial Officer of KLXE from September 2018 until April 30, 2020. Given that Mr. McCaffrey has not served as an executive officer of the Company for over three years, and considering the full transition of the KLXE management team at the time of the QES Merger, the Board believes that Mr. McCaffrey has no relationship which would interfere with the exercise of independent judgment in carrying out his responsibilities as a director, including his ability to be independent from current management.

BOARD LEADERSHIP STRUCTURE

The Board believes it is in the best interests of the Company and its stockholders for the Board to have flexibility in determining the Board leadership structure of the Company. As part of our ongoing, proactive efforts to implement effective corporate governance practices, the Nominating and Corporate Governance Committee regularly reviews the leadership structure of the Board, taking into account the Company and its needs, legislative and regulatory developments, and corporate governance trends, among other things. Accordingly, the Board has determined that the roles of Chairman of the Board and President and Chief Executive Officer should presently remain separate and that an independent director should serve as the Chairman of the Board. Mr. Skindlo, an independent director, has served as non-executive Chairman of the Board since June 2022. The Board believes that the current leadership of the Board, when combined with the other elements of its corporate governance structure, strikes an appropriate balance between strong leadership and independent oversight of the Company’s business and affairs.

11

The Board is composed of a majority of independent directors. Seven out of the eight members of the Board are independent, and the chair and members of each of the Board’s Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee are independent directors. The Company’s independent directors bring experience, oversight and expertise from outside the Company. As a result, independent directors oversee all significant matters affecting KLXE, including the Company’s financial statements, executive compensation matters, the nomination and assessment of directors and the risk management practices. Independent directors regularly meet in executive sessions not attended by management in conjunction with each regular Board and committee meeting and as they otherwise deem appropriate.

At each executive session, the respective chair of the Board committee relating to the specific matter discussed by the independent directors, leads the discussion. For example, the chair of the KLXE Nominating and Corporate Governance Committee leads the discussions with respect to director nominations, the current composition of the Board and other Board policy matters.

Following each executive session, the independent directors report the results of the discussions to the full Board, as appropriate. These discussions are led by the appropriate committee chair. Additional executive sessions may be convened at any time at the request of an independent director and, in such event, the independent director chairman of the committee most closely associated with the discussed topic leads the discussion and the report to the full Board. During executive sessions, directors also discuss and propose matters to be included in the agenda for future Board meetings.

MEETINGS OF THE BOARD AND ITS COMMITTEES

During 2023, the Board held eight meetings and met in executive session on four of those occasions. Committee meetings were held in 2023 as follows:

Committee Name	Number of Meetings
Audit Committee		4
Compensation Committee		4
Nominating and Corporate Governance Committee		4

All members of the Board attended at least 75% of the aggregate of the total number of meetings of the Board and the total number of meetings held by each committee on which he served in 2023.

From time to time between meetings, Board and committee members confer with each other and with management and independent consultants regarding relevant issues, and representatives of management may meet with such consultants on behalf of the relevant committee.

Directors are expected to attend meetings of the Board and of committees on which they serve and to spend the time needed and meet as frequently as necessary to properly discharge their responsibilities. Directors are encouraged but not required to attend our annual stockholder meetings. Each member of our Board attended our 2023 Annual Meeting of Stockholders.

COMMITTEES OF THE BOARD

The Board has three standing committees: the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee. Copies of the charters for the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee are available on our website, www.klx.com, in the Investor Relations section. Please note that the information contained in or connected to our website is not a part of this Proxy Statement and will not be deemed incorporated by reference unless expressly stated otherwise.

12

Audit Committee

The Audit Committee is composed of Messrs. Collins, Eliassen, Skindlo, with Mr. Whates serving as Chairman. All directors serving on the Audit Committee are independent committee members as defined by Nasdaq and SEC rules. Our Board has determined that Mr. Whates is an “audit committee financial expert” in accordance with SEC rules.

The Audit Committee is responsible for the appointment, compensation and oversight of our independent auditors, overseeing the quality and integrity of our financial statements and related disclosures, our compliance with legal and regulatory requirements, assessing our independent auditors’ qualifications, independence and performance, monitoring the performance of our internal audit and control functions, and overseeing cybersecurity and data privacy matters.

Compensation Committee

The Compensation Committee is currently composed of Messrs. Collins, Eliassen and Whates, with Mr. Robertson serving as Chairman. All of the members of the Compensation Committee are independent as defined by Nasdaq rules.

The Compensation Committee provides recommendations to the Board regarding compensation matters and oversees the Company’s incentive and compensation plans. Together with management (with the exception of compensation matters related to our Chief Executive Officer), and any counsel or other advisors it deems appropriate, including the Compensation Committee’s consultant F.W. Cook (“FWC”), the Compensation Committee reviews and discusses each particular executive compensation matter presented and makes a final recommendation to the Board for consideration. For example, the Compensation Committee reviews and approves the compensation of our executive officers and makes appropriate adjustments based on Company performance, achievement of predetermined goals, and changes in an executive officer’s duties and responsibilities.

The Compensation Committee has the power to delegate its authority and duties to subcommittees or individual members of the Compensation Committee or, to the extent permitted by the terms of any plan, to officers of our Company or other persons in each case as it deems appropriate in accordance with applicable laws and regulations and the requirements of Nasdaq. Management input is taken into consideration in assessing the performance and pay levels of our key management employees as well as the establishment of bonus measures and targets, but ultimate decision-making regarding compensation of our NEOs remains with the Compensation Committee and ultimately the Board.

To gain a perspective on external pay levels, emerging practices and regulatory changes, the Compensation Committee of the Board engaged an outside executive compensation consultant to provide benchmark and survey information and advise the Compensation Committee as it reviewed our executive and director compensation programs. The Compensation Committee selected FWC as its consultant. Historically, the Compensation Committee has tasked its outside executive compensation consultant with gathering market competitive data, reviewing compensation plan design alternatives and advising the Compensation Committee on director and executive compensation trends and best practices.

The compensation consultant reports to, and is directed by, the Compensation Committee, which has sole authority to retain or terminate compensation advisers. The Compensation Committee reviewed information regarding the independence and potential conflicts of interest of FWC, taking into account, among other things, the factors set forth in the Nasdaq listing standards. Based on this review, the Compensation Committee concluded that the engagement of FWC did not raise any conflicts. Other than services provided for the Compensation Committee, the compensation consultants did not provide additional services to the Company for the year ended December 31, 2023.

13

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee is composed of Messrs. Collins, Robertson, Skindlo and Whates and Ms. Hunter, with Mr. Eliassen serving as Chairman. The Nominating and Corporate Governance Committee is responsible for, among other things, assisting the Board by actively identifying individuals qualified to become Board members, recommending to the Board the director nominees for election at the next annual meeting of stockholders and making recommendations with respect to corporate governance matters. All members of the Nominating and Corporate Governance Committee are or were independent as defined by the Nasdaq rules.

NOMINATION OF DIRECTORS

As provided in its charter, the Nominating and Corporate Governance Committee identifies and recommends to our Board nominees for election and re-election to the Board and will consider nominations submitted by stockholders. The Nominating and Corporate Governance Committee, in consultation with the Chairman of the Board, evaluates candidates proposed by stockholders using the same criteria as for other candidates.

The Chairman of the Board and the Nominating and Corporate Governance Committee seek to create a Board that is strong in its collective knowledge and has a diversity of skills, backgrounds and experience with respect to leadership, business operations, finance and industry knowledge. The Nominating and Corporate Governance Committee reviews with the Chairman of the Board and the full Board, on a periodic basis, the current composition of the Board in light of the characteristics of independence, skills, experience and availability of service to the Company of its members and of the Company’s anticipated needs. The Board also actively seeks refreshment of the Board with directors who can provide diverse perspectives and add unique value through skills highly relevant to our corporate strategy. Further, the Nominating and Corporate Governance Committee carefully considers the ability of incumbent directors to continue to contribute to the Board and the Company’s evolving needs, as part of the renomination process. All of our independent directors serve on Board Committees, further supporting the Board by providing experience to those Committees. The needs of each Committee are also reviewed when considering nominees to the Board.

When the Nominating and Corporate Governance Committee reviews a potential new candidate, it looks specifically at the candidate’s qualifications in light of the size of the Board and the needs of the Board and the Company at a given point in time. In nominating director candidates, the Nominating and Corporate Governance Committee strives to nominate directors who exhibit high standards of ethics, integrity, commitment and accountability. In addition, all nominations attempt to ensure that the Board shall encompass a range of talent, skills, expertise and industry experience sufficient to provide guidance with respect to our operations and activities.

Under our Nominating and Corporate Governance Committee charter, directors must inform the Chairman of the Board and the Chairman of the Nominating and Corporate Governance Committee in advance of accepting an invitation to serve on another public company board. In addition, no director may sit on the board of directors, or beneficially own more than 1% of the outstanding equity securities, of any of our competitors in our principal lines of business. We also discourage our directors from serving on the board of directors of more than three public companies.

To recommend a nominee, a stockholder shall give notice to our Corporate Secretary at our principal executive offices located at 3040 Post Oak Boulevard, 15th Floor, Houston, TX 77056. The form and substance of the nominations must satisfy the requirements established by our Fourth Amended and Restated Bylaws and the SEC. This notice should include the candidate’s brief biographical description, a statement of the qualifications of the candidate, taking into account the qualification requirements set forth above, and the candidate’s signed consent to be named in the Proxy Statement and to serve as a director if elected. The notice

14

must be given (i) with regard to nominations to be brought before an annual meeting to be held on a day not more than 30 days in advance of the anniversary of the previous year’s meeting nor more than 70 days after the anniversary of the previous year’s meeting, not later than 90 days nor earlier than 120 days in advance of the anniversary of the previous year’s meeting or (ii) with regard to nominations for any other annual meeting, within ten days following the public announcement of the date of such meeting. Once we receive the nomination and written request for a questionnaire, we will deliver a questionnaire to the candidate that requests additional information about the candidate’s independence, qualifications and other information that would assist the Nominating and Corporate Governance Committee in evaluating the candidate, as well as certain information that must be disclosed about the candidate in our Proxy Statement, if nominated. Candidates must complete and return the questionnaire within the time frame provided to be considered for nomination by the Nominating and Corporate Governance Committee.

The Nominating and Corporate Governance Committee has not received any nominations for director from stockholders for the Annual Meeting.

BOARD DIVERSITY

The Chairman of the Board and the Nominating and Corporate Governance Committee, in accordance with the Board’s governance principles, seek to create a Board that, as a whole, is strong in its collective knowledge and diverse in its perspective, skills and experience with respect to industry knowledge, background, vision and strategy, human resource management, general management and leadership, marketing, business operations, business judgment, crisis management, risk assessment, accounting and finance, capital markets, general corporate governance and global markets. The Board also added a gender diverse member in March 2024.

In considering candidates for the Board, the Nominating and Corporate Governance Committee considers the entirety of each candidate’s credentials in the context of these standards and such other factors that the Nominating and Corporate Governance Committee considers appropriate so that the Board includes members, if suitable, with diverse backgrounds, perspectives, skills and experience, who are likely to serve the Company’s anticipated needs, enhance Board effectiveness and address the interests of our stockholders. The Nominating and Corporate Governance Committee believes our Board is appropriately balanced with directors from varied sectors, with significant understanding of our business and industries, has extensive experience in general management, human resources, marketing, engineering, capital markets, developing and executing mergers and acquisition strategies, including successful integration activities related thereto, as founders or co-founders of a multitude of businesses, and the collective experiences developed during their business careers in various industries, including oil and natural gas and related industries.

BOARD DIVERSITY MATRIX

PLURALITY PLUS MAJORITY VOTING FOR DIRECTORS

Under the Company’s Amended and Restated Certificate of Incorporation, in order for a director to be elected at an annual meeting, a plurality of the votes cast with respect to the director’s election must be cast “for” the director. Abstentions and broker non-votes are excluded from calculation of the vote results. In an uncontested election of directors, any director who receives the same or a greater number of “withheld” votes than votes “for” their election shall promptly tender their resignation to the Chairman of the Board. The Chairman of the Board then recommends to the Board whether to accept or reject the resignation, and the Board must make a decision by 90 days after the date of the meeting at which the election took place. Any director who tenders a resignation does not participate in this decision. The Company shall then make a public announcement of the Board’s decision to accept or reject the resignation.

RISK OVERSIGHT

Our Risk Management Framework

KLXE has adopted enterprise risk management policies based on the Integrated Framework of the Committee of Sponsoring Organizations. Under KLXE’s policies, the Company’s Senior Vice President and Chief Accounting Officer, in conjunction with Vice President of Operations, is responsible for identifying risks that could affect achievement of business goals and strategies, assessing the likelihood and potential impact of significant risks over various timeframes and prioritizing risks and actions to be taken in response. The Vice President of Operations reports to KLXE’s Chief Executive Officer on actions to monitor and manage significant risks in order to remain within KLXE’s range of risk tolerance.

The Chief Executive Officer, Chief Financial Officer and General Counsel of the Company periodically report on KLXE’s risk management policies, practices and identified risks and mitigation plans to relevant Board committees and to the full Board. If necessary, the Board has access to any employee without management involvement and access to whistleblower and any other reports of alleged wrongdoing. The Audit Committee annually reviews major financial risk exposures and a number of operational, compliance, reputational and strategic risks, including cyber risks, as well as practices to monitor and manage those risks. The Audit Committee also reviews overall policies and practices for enterprise risk management, including the delegation of practices and a number of significant risks in the course of their reviews of corporate strategy, business plans, reports of Board committee meetings and other presentations, including presentations from the Company’s director of information technology.

The Board and the Compensation Committee believe our compensation incentives reflect the appropriate balance between opportunity and risk, and will encourage executives to act in a manner consistent with this balance, which is aligned to the interests of our stockholders. We mitigate compensation-related risks to our long-term performance, ethical standards and reputation in the following ways:

What We Do

DELINQUENT SECTION 16(A) REPORTS

Under Section 16(a) of Securities Exchange Act of 1934 (as amended, the “Exchange Act”) and SEC rules, our directors, executive officers and beneficial owners of more than 10% of any class of equity security are required to file periodic reports of their ownership, and changes in that ownership, with the SEC. Based on our review of the filed reports, we believe that all Section 16(a) filing requirements were in compliance during the fiscal year ended December 31, 2023, except for a Form 4, filed by Stuart D. Porter, a beneficial owner of more than 10% of shares of the Company’s outstanding common stock, on July 7, 2023, related to an in-kind distribution made on June 15, 2023, and a Form 4, filed on September 27, 2023 for Geoffrey C. Stanford, a Section 16 officer of the Company, regarding restricted stock awards that vested on April 1, 2022 and March 1, 2023.

ANTI-HEDGING AND ANTI-PLEDGING POLICY

Our Board previously established a policy that prohibits our directors and executive officers from engaging in short sales of our securities. Our directors and executive officers are also prohibited from selling or purchasing puts or calls, trading in or writing options, or engaging in other hedging activities with respect to our securities. Directors and executive officers are also prohibited from holding Company securities in a margin account or pledging our securities as collateral for a loan, unless pre-clearance is obtained after the director or executive officer clearly demonstrates the financial capability to repay the loan without resorting to the pledged securities.

COMPENSATION OF DIRECTORS

We believe that attracting and retaining qualified non-employee directors is critical to the future value of our growth and governance. Accordingly, we maintain a comprehensive director compensation policy for our non-employee directors, which consists of:

• An annual cash retainer of $120,000 for each non-employee director except the non-executive Chairman of the Board who receives an annual cash retainer of $170,000, in each case, payable quarterly in arrears;

• An annual equity-based award granted to each non-employee director with an aggregate fair market value of approximately $55,000 on the date of grant; and

• An annual cash fee of $10,000 payable to each chair of the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee.

Our non-employee directors are reimbursed for certain reasonable expenses incurred in connection with their services to us.

PROPOSAL 3: ADVISORY, NON-BINDING VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

Background

Our Board is committed to excellence in governance. As part of this commitment, and as required by Rule 14a-21 of the Exchange Act, our Board is providing our stockholders with an opportunity to cast an advisory, non-binding vote on a resolution to approve the compensation of our NEOs. This proposal gives our stockholders the opportunity to express their views on the Company’s executive compensation and is commonly referred to as a “say-on-pay” proposal.

As described below under “Executive Compensation—Additional Narrative Disclosures,” we have developed a compensation program that is designed to attract, retain and motivate key executives responsible for our success, to provide incentives that reward achievement of performance goals that directly correlate to the enhancement of stockholder value and to align our executives’ interests with those of our stockholders by rewarding short-term and long-term performance and tying a significant portion of our executive officers’ compensation to increases in stockholder value. We believe our executive compensation program strikes an appropriate balance between the implementation of responsible, measured compensation practices and the effective provision of incentives for our NEOs to exert their best efforts for our success.

We are asking for stockholder approval, on an advisory, non-binding basis, of the compensation of our NEOs as disclosed in this proxy statement pursuant to Item 402 of Regulation S-K, which includes the disclosures in the “Executive Compensation—Additional Narrative Disclosures” section below, the compensation tables and any related material disclosed in this proxy statement. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our NEOs and the policies and practices described in this proxy statement. For the reasons discussed above, our Board unanimously recommends that our stockholders vote in favor of the following resolution:

“RESOLVED, that the Company’s stockholders hereby approve, on an advisory basis, the compensation of the named executive officers, as disclosed in the Company’s proxy statement for the 2024 Annual Meeting of Stockholders pursuant to Item 402 of Regulation S-K, including the Additional Narrative Disclosures, the compensation tables and any related material disclosed in the proxy statement.”

As this vote is advisory, it will not be binding on our Board or our Compensation Committee, and neither our Board nor our Compensation Committee will be required to take any action as a result of the outcome of the vote. However, our Compensation Committee will carefully consider the outcome of this vote when considering future executive compensation policies and decisions.

Required Vote of Stockholders

Approval of the resolution to approve the compensation of our NEOs requires the affirmative vote of the recordholders of a majority in voting power of the shares present virtually or by proxy at the meeting and entitled to vote on such question. As a result, abstentions will have the same effect as a vote “AGAINST” the proposal and broker non-votes will have no effect on the vote outcome.

THE BOARD RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE SAY-ON-PAY RESOLUTION.

24

PROPOSAL 4: ADVISORY, NON-BINDING VOTE TO APPROVE THE FREQUENCY OF FUTURE ADVISORY VOTES ON NEO EXECUTIVE COMPENSATION

Background

We are required by Rule 14a-21 of the Exchange Act to provide stockholders with a separate advisory (non-binding) vote for the purpose of asking stockholders to express their preference for the frequency of future advisory votes to approve the compensation of our NEOs. Stockholders may indicate whether they would prefer an advisory vote to approve the compensation of our NEOs every one, two or three years (or abstain from voting). We are required to solicit stockholder votes on the frequency of future advisory votes to approve the compensation of our NEOs at least once every six years, although we may seek stockholder input more frequently.

The frequency period that receives the most votes (every one, two or three years) will be deemed to be the recommendation of the stockholders. However, because this vote is advisory and not binding on the Board or the compensation committee, the Board may decide that it is in the best interests of our stockholders and the Company to hold an advisory vote to approve the compensation of our NEOs more or less frequently than the option selected by a plurality of our stockholders. The Board will, however, carefully consider the outcome of this vote when considering the frequency of future advisory votes to approve the compensation of our NEOs.

The Board believes there is a reasonable basis for holding the advisory vote to approve the compensation of our NEOs every one, two or three years; less frequent votes encourage a more long-term analysis of the Company’s executive compensation programs and would avoid the burden that annual votes would impose on stockholders required to evaluate the executive compensation program each year, but more frequent votes provide stockholders with the opportunity to react to emerging trends in compensation and give the Board and the compensation committee the opportunity to evaluate the compensation program each year in light of timely input from stockholders. The Board believes it is best practice to hold the advisory vote to approve the compensation of our NEOs every year.

Therefore, the Board recommends that the stockholders vote to hold the advisory vote to approve the compensation of our NEOs every year. Stockholders are not voting, however, to approve or disapprove of this particular recommendation. The proxy card provides four choices, and stockholders are entitled to vote on whether the advisory vote to approve the compensation of our NEOs shall be held every one, two or three years or to abstain from voting.

Required Vote of Stockholders

The frequency period that receives the most votes (every one, two or three years) will be deemed to be the recommendation of the stockholders. As a result, abstentions and broker non-votes will have no effect on the vote outcome.

THE BOARD RECOMMENDS A VOTE TO HOLD FUTURE ADVISORY VOTES TO APPROVE THE COMPENSATION OF OUR NEOS “EVERY YEAR.”

25

EXECUTIVE COMPENSATION

We are currently considered a “smaller reporting company” within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), for purposes of the SEC’s executive compensation disclosure rules.

Further, our reporting obligations generally extend only to our NEOs who are (i) the individual who served as our Chief Executive Officer and (ii) our next two most highly compensated executive officers who were serving as of December 31, 2023.

Under each employment agreement, if the executive officer’s employment is terminated for good reason or without cause within 12 months of a change in control, which includes the consummation of the QES Merger, then, in lieu of the severance benefits described in the preceding paragraph, the executive officer will be entitled to receive: (i) the pro-rata value through the date of termination of the executive officer’s target bonus for the year in which the termination occurs, (ii) a lump sum payment equal to (A) for Mr. Baker, two and one-half times Mr. Baker’s base salary or (B) for Messrs. Lehner and Bouthillette, two times the executive officer’s base salary, (iii) an amount equal to (A) for Mr. Baker, two and one-half times Mr. Baker’s target bonus for the year in which the termination occurs or (B) for Messrs. Lehner and Bouthillette, two times the executive officer’s target bonus for the year in which the termination occurs, and (iv) for a period of 18 months following such termination, reimbursement of the COBRA Premium.

29

Each employment agreement also contains certain restrictive covenants, including provisions that generally prohibit the executive officer from competing with KLXE and its affiliates or soliciting clients, executives, officers, directors or other employees of KLXE and its affiliates. These restrictions generally apply during the term of the executive officer’s employment and for a period of one year following the termination of such employment.

The employment agreements do not provide a tax gross-up provision for federal excise taxes that may be imposed under Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”). Instead, if the payments and benefits provided to an executive officer constitute “parachute payments” within the meaning of

Section 280G of the Code and are subject to the excise tax imposed by Section 4999 of the Code, then the payments and benefits will be either (i) delivered in full or (ii) delivered to such lesser extent as would result in no portion of such amounts being subject to such excise tax, whichever alternative produces the best net after tax position for the executive officer.

Other Benefits

We offer participation in broad-based retirement, health and welfare plans to all of our employees. We maintain a plan intended to provide benefits under section 401(k) of the Code, where employees are allowed to contribute portions of their base compensation into a retirement account in order to encourage all employees, including any participating NEOs, to save for the future. We provide matching contributions equal to 3% of the first 6% of each employee’s eligible compensation contributed to the plan.

PAY VERSUS PERFORMANCE

In accordance with Item 402(v) of Regulation S-K, we are providing the following disclosure regarding executive compensation for our principal executive officer (“PEO”), and non-PEO NEOs and Company performance for the fiscal years listed below. The Compensation Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the years shown.

The amounts set forth below under the headings “Compensation Actually Paid to PEO” and “Average Compensation Actually Paid to Non-PEO NEOs” have been calculated in a manner consistent with Item 402(v) of Regulation S-K. Use of the term “compensation actually paid” is required by the SEC’s rules, and as a result of the calculation methodology required by the SEC, such amounts differ from compensation actually received by the individuals for the fiscal years listed below.

Year	Summary Compensation Table Total for PEO (1)		Compensation Actually Paid to PEO (1) (2) (3)		Average Summary Compensation Table Total for Non- PEO NEOs (1)		Average Compensation Actually Paid to Non-PEO NEOs (1) (2) (3)		Value of Initial Fixed $100 Investment Based On Total Shareholder Return		Net Income (Loss) (in millions)
2023	$	2,302,588	$	1,224,469	$	1,133,610	$	739,298	$	263.23	$	19.2
2022	$	4,388,143	$	7,258,468	$	2,135,365	$	3,154,975	$	458.39	$	(3.1	)

(1) The PEO reflected in these columns represents Christopher J. Baker and the non-PEO NEOs reflected in these columns represent Keefer M. Lehner and Max L. Bouthillette, for 2023 and 2022.

(2) The following supplemental tables present a reconciliation of Mr. Baker’s and the non-PEO NEOs’ “Summary Compensation Table” totals to the “compensation actually paid” for the applicable year, computed in accordance with Item 402(v) of Regulation S-K. As Mr. Baker and the non-PEO NEOs do not participate in any defined benefit plans, no adjustments were required to amounts reported in the Summary Compensation Table totals related to the value of benefits under such plans.

(3) Equity valuation assumptions for calculating “compensation actually paid” are not materially different from grant date valuation assumptions.

Narrative Disclosure to Pay Versus Performance Table

The PEO’s and other NEO’s “compensation actually paid” generally align with the Company’s total shareholder return over the two years presented in the table. This is primarily because a significant portion of the “compensation actually paid” to the PEO and other NEOs is comprised of equity-based awards. The PEO’s and other NEO’s “compensation actually paid” is not significantly impacted by the Company’s net income. While net income is not directly used in determining compensation levels or equity-based award payouts, it is a factor in the determination of performance achievement under the Company’s incentive compensation program.

PROPOSAL 5: AMENDMENT TO THE COMPANY’S AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO ELIMINATE THE SUPERMAJORITY VOTING REQUIREMENT TO AMEND THE COMPANY’S BYLAWS

Background

Our Amended and Restated Certificate of Incorporation provides that the affirmative vote of the holders of at least sixty-six and two-thirds percent (66 2/3%) of the outstanding shares of stock of the Company, voting as a single class, shall be required to effect the amendment, repeal or adoption by the stockholders of any bylaw adopted or amended by the Board (the “Bylaw Supermajority Voting Requirement”). The Bylaw Supermajority Amendment will eliminate the Bylaw Supermajority Voting Requirement. The Board has unanimously approved the Bylaw Supermajority Amendment, subject to stockholder approval. The Board has unanimously determined that the Bylaw Supermajority Amendment is advisable and in the best interests of the Company and our stockholders, and, in accordance with the DGCL, hereby seeks approval of the Bylaw Supermajority Amendment by our stockholders.

Proposed Bylaw Supermajority Amendment

The Board is asking our stockholders to approve the amendment to Article IX of our Amended and Restated Certificate of Incorporation. The text of the Bylaw Supermajority Amendment is attached hereto as Appendix C, with additions marked with bold, underlined text and deletions indicated by strike-out text.

Reasons for the Supermajority Amendments

The Nominating and Corporate Governance Committee of our Board regularly considers a broad range of corporate governance issues and is committed to adopting governance practices that are beneficial to the Company and our stockholders. The elimination of the Bylaw Supermajority Voting Requirement and the Charter Supermajority Voting Requirement (defined below; together, the “Supermajority Voting Requirements”) in corporate governance documents is increasingly considered an important aspect of good corporate governance and a concern to many of our investors.

Our Board implemented the current Supermajority Voting Requirements because it believed such thresholds were an important piece of the Company’s governance structure in order to promote continuity and stability and were in the best interests of the Company and its stockholders. The Board also believed that such supermajority voting thresholds enhanced the independence of our directors from special interests and protected the Company from unfair and abusive takeover practices.

Our Board recognizes that removing the Supermajority Voting Requirements is consistent with generally held views of evolving corporate governance practices. Our Board has listened to the views of stockholders and the investor community on this issue and has also considered the limited benefits of the Supermajority Voting Requirements to the Company and its stockholders. In addition, our Board acknowledges that many other public companies have transitioned away from these kinds of supermajority voting provisions. The Board has also considered the fact that removing the Supermajority Voting Requirements will make future amendment of aspects of our Amended and Restated Certificate of Incorporation possible with the affirmative votes of fewer stockholders. In view of these considerations, our Board has unanimously determined to eliminate the Supermajority Voting Requirements as proposed.

Effectiveness of the Bylaw Supermajority Amendment

If the Bylaw Supermajority Amendment is approved by our stockholders, the Bylaw Supermajority Amendment will become effective upon the filing of a Second Amended and Restated Certificate of Incorporation with the Delaware Secretary of State, which filing is expected to occur as soon as reasonably

32

practicable after the Annual Meeting. If the Bylaw Supermajority Amendment is not approved by our stockholders, the Amended and Restated Certificate of Incorporation will not be amended, and the Bylaw Supermajority Voting Requirement will remain in effect.

Required Vote of Stockholders

Approval of the Bylaw Supermajority Amendment requires the affirmative vote of 66 2/3% in voting power of the outstanding voting stock of the Company, voting together as a single class. As a result, abstentions and broker non-votes will have the same effect as a vote “AGAINST” this proposal.

This Proposal 5 is separate from, and is not conditioned on, the approval of Proposal 1 (the Declassification Amendment) or Proposal 6 (the Charter Supermajority Amendment). Your votes on Proposals 1 and 6 do not affect your vote on Proposal 5. You can vote FOR, AGAINST, or ABSTAIN from voting on any of these proposals.

THE BOARD RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE PROPOSED AMENDMENT TO THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO ELIMINATE THE SUPERMAJORITY VOTING REQUIREMENT TO AMEND THE COMPANY’S BYLAWS.

33

PROPOSAL 6: AMENDMENT TO THE COMPANY’S AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO ELIMINATE THE SUPERMAJORITY VOTING REQUIREMENT TO AMEND THE COMPANY’S CHARTER

Background

Our Amended and Restated Certificate of Incorporation provides that the affirmative vote of the holders of at least sixty-six and two-thirds percent (66 2/3%) of the outstanding shares of stock of the Company, voting as a single class, shall be required to effect the amendment, repeal or adoption of certain provisions of the Amended and Restated Certificate of Incorporation (the “Charter Supermajority Voting Requirement”). The Charter Supermajority Amendment will eliminate the Charter Supermajority Voting Requirement. Consequently, if the Charter Supermajority Amendment is adopted, our certificate of incorporation will not require that a proposed amendment, alteration, change or repeal of any provision in our certificate of incorporation be subject to approval by a supermajority of our stockholders. The Board has unanimously approved the Charter Supermajority Amendment, subject to stockholder approval. The Board has unanimously determined that the Charter Supermajority Amendment is advisable and in the best interests of the Company and our stockholders, and, in accordance with the DGCL, hereby seeks approval of the Charter Supermajority Amendment by our stockholders.

Proposed Charter Supermajority Amendment

The Board is asking our stockholders to approve the amendment to Article X of our Amended and Restated Certificate of Incorporation. The text of the Charter Supermajority Amendment is attached hereto as Appendix D, with additions marked with bold, underlined text and deletions indicated by strike-out text.

Reasons for the Charter Supermajority Amendment

Please see the discussion above in “Reasons for the Supermajority Amendments” in Proposal 5 (the Bylaw Supermajority Amendment), which discusses the Board’s reasoning for eliminating all supermajority voting requirements in the Company’s Amended and Restated Certificate of Incorporation.

Effectiveness of the Charter Supermajority Amendment

If the Charter Supermajority Amendment is approved by our stockholders, the Charter Supermajority Amendment will become effective upon the filing of a Second Amended and Restated Certificate of Incorporation with the Delaware Secretary of State, which filing is expected to occur as soon as reasonably practicable after the Annual Meeting. If the Charter Supermajority Amendment is not approved by our stockholders, the Amended and Restated Certificate of Incorporation will not be amended, and the Charter Supermajority Voting Requirement will remain in effect.

Required Vote of Stockholders

Approval of the Charter Supermajority Amendment requires the affirmative vote of 66 2/3% in voting power of the outstanding voting stock of the Company entitled to vote thereon, voting together as a single class. As a result, abstentions and broker non-votes will have the same effect as a vote “AGAINST” this proposal.

This Proposal 6 is separate from, and is not conditioned on, the approval of Proposal 1 (the Declassification Amendment) or Proposal 5 (the Bylaw Supermajority Amendment). Your votes on Proposals 1 and 5 do not affect your vote on Proposal 6. You can vote FOR, AGAINST, or ABSTAIN from voting on any of these proposals.

THE BOARD RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE PROPOSED AMENDMENT TO THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO ELIMINATE THE SUPERMAJORITY VOTING REQUIREMENT TO AMEND THE COMPANY’S CERTIFICATE OF INCORPORATION.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Greene’s Transaction

On March 8, 2023, we completed the acquisition of all of the equity interests of Greene’s Energy Group, LLC (“Greene’s”), including $1.7 million in cash remaining with Greene’s (the “Greene’s Acquisition”), pursuant to that certain purchase and sale agreement dated March 8, 2023, between Greene’s Holding Corporation, the direct parent of Greene’s (“Greene’s Seller”), and the Company (the “Purchase Agreement”). The total consideration for the Greene’s Acquisition under the Purchase Agreement consisted of the issuance of approximately 2.4 million shares of the Company’s common stock, par value $0.01 per share (the “Stock Consideration”), subject to customary post-closing adjustments, representing 14.7% of the fully diluted common stock of the Company with an implied enterprise value of approximately $30.3 million based on a 30-day volume weighted average price as of March 7, 2023 less acquired cash.

Registration Rights Agreements

On March 8, 2023, we entered into a Registration Rights and Lock-Up Agreement with Greene’s Seller in connection with the Greene’s Acquisition, pursuant to which Greene’s Seller and certain of its affiliates will have certain shelf, underwritten offering and piggyback rights with respect to the Stock Consideration upon the terms and subject to the conditions set forth therein. The Registration Rights and Lock-Up Agreement also provides that we will pay certain expenses relating to such registrations and indemnify the registration rights holders against certain liabilities which may arise under the Securities Act.

Additionally, pursuant to the terms of the Greene’s Registration Rights and Lock-Up Agreement, Greene’s Seller agreed, subject to certain customary exceptions, not to, directly or indirectly, sell, offer or agree to sell, or otherwise transfer, or loan or pledge, through swap or hedging transactions, or grant any option to purchase, make any short sale or otherwise dispose of 66 2/3% of the Stock Consideration for specified periods of time ranging from six to twelve months following the closing of the acquisition, as described therein.

On May 3, 2020, we entered into a registration rights agreement with certain stockholders, including Archer Holdco LLC, Geveran Investments Limited, Famatown Finance Limited, Robertson QES Investment LLC, Quintana Energy Partners—QES Holdings LLC, Quintana Energy Fund—TE, L.P. and Quintana Energy Fund—FI, L.P., each a former 5% stockholder of the Company, relating to the shares of KLXE common stock issued as the merger consideration to such holders under the merger agreement related to the QES Merger, pursuant to which such stockholders have certain shelf, demand registration and piggyback rights upon the terms and subject to the conditions set forth therein. The registration rights agreement also provides that we will pay certain expenses relating to such registrations and indemnify the registration rights holders against certain liabilities which may arise under the Securities Act.

On September 14, 2018, we entered into registration rights agreements with each of Amin J. Khoury and Thomas P. McCaffrey. Under the registration rights agreements, each of Amin J. Khoury and Thomas P. McCaffrey have demand registration and customary piggyback registration rights. The registration rights agreements also provide that we will pay certain expenses relating to such registrations and indemnify the registration rights holders against certain liabilities which may arise under the Securities Act. We may also file a resale/reoffer prospectus related to the sale of restricted stock held by each of Amin J. Khoury and Thomas P. McCaffrey.

Procedures for Review, Approval and Ratification of Transactions with Related Persons

Our Amended and Restated Certificate of Incorporation provides that no contract or transaction between us and one or more of our directors or officers (including entities or other organizations in which one or more of our directors or officers have a financial interest), shall be void or voidable solely for that reason, or because such

35

director or officer is present at, participates in, or vote is counted at the meeting where the contract or transaction is authorized, if (i) the material facts of the director’s or officer’s interest in the contract or transaction are disclosed to or known by the Board or committee thereof and the Board or such committee thereof in good faith authorizes the contract or transaction by an affirmative vote of a majority of the disinterested directors (even if less than a quorum), (ii) the material facts of the director’s or officer’s interest in the contract or transaction are disclosed to or known by the stockholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by a vote of the stockholders or (iii) the contract or transaction is fair to our Company at the time that it is authorized, approved or ratified by the Board, a committee thereof or the stockholders.

Our Board adopted a written policy pursuant to which our Audit Committee will be presented with a description of any related party transactions for them to consider for approval. The policy is designed to operate in conjunction with and as a supplement to the provisions of our Code of Business Conduct, a copy of which is posted on our website (www.klx.com).

The policy generally provides that our management gather information with respect to actual or potential related party transactions and then present to the Audit Committee for approval any transaction to which the Company or any of its subsidiaries is a participant at or above an amount which exceeds $120,000 in which the related person may have a direct or indirect interest. In determining whether to approve or ratify a related party transaction, we expect the Audit Committee to consider the following: whether the related party transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related party’s interest in the related party transaction. The policy also identifies certain types of transactions that our Board has pre-identified as not involving a direct or indirect material interest and are, therefore, not considered related party transactions for purposes of the policy.

Furthermore, under our Code of Business Conduct, our Law Department will review all proposed transactions between the Company and a related person (such as an individual related to a Company employee, or such director’s family), together with all information concerning the proposed transaction. In determining whether the proposed transaction will be approved, the factors our Law Department may consider include (i) whether the transaction was the product of fair dealing, taking into account the timing, initiation, structure and negotiations of the transaction, and whether the related person’s interest was disclosed to us, (ii) whether similar terms would have been obtained from arm’s length negotiations with a third party and (iii) the availability of other sources for comparable products or services.

PROPOSAL 7: RATIFICATION OF THE SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has selected Deloitte & Touche LLP as independent registered public accounting firm to audit the consolidated financial statements for the year ending December 31, 2024 and presents this appointment to the stockholders for ratification.

Although stockholder approval of this appointment is not required, the Audit Committee and the Board believe that submitting the appointment to the stockholders for ratification is a matter of good corporate governance. If the stockholders do not ratify the appointment, the Audit Committee will review its future selection of independent registered public accounting firm, but still may retain them. Even if the appointment is ratified, the Audit Committee, at its discretion, may change the appointment at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.

Deloitte & Touche LLP acted as our independent registered public accounting firm for the 2023 fiscal year. In addition to its audit of our consolidated financial statements, the member firms of Deloitte Touche Tohmatsu Limited and their respective affiliates performed certain non-audit services.

A representative of Deloitte & Touche LLP is expected to be present at the meeting and will be afforded the opportunity to make a statement if he or she desires to do so and to respond to appropriate questions from stockholders.

For information concerning the appointment of Deloitte & Touche LLP, see Report of the Audit Committee of the Board of Directors above. For information concerning fees paid to Deloitte & Touche LLP, the member firms of Deloitte Touche Tohmatsu Limited and their respective affiliates, see “Principal Accountant Fees and Services” below.

Required Vote of Stockholders

Ratification of the selection of Deloitte & Touche, LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024 requires the affirmative vote of the recordholders of a majority in voting power of the shares present virtually or by proxy at the meeting and entitled to vote on such question. As a result, abstentions will have the same effect as a vote “AGAINST” the proposal and broker non-votes will have no effect on the vote outcome.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE RATIFICATION OF THE SELECTION OF DELOITTE & TOUCHE LLP.

37

AUDIT MATTERS

Deloitte & Touche LLP has audited the financial statements of the Company since 2018.

When considering Deloitte & Touche LLP’s independence, the Audit Committee considered whether its provision of services to the Company beyond those rendered in connection with its audit and review of the Company’s consolidated financial statements was compatible with maintaining its independence and has determined that such services do not interfere with that firm’s independence in the conduct of its auditing function. The Audit Committee also reviewed, among other things, the amount of fees paid to Deloitte & Touche LLP, the member firms of Deloitte Touche Tohmatsu Limited and their respective affiliates for audit and non-audit services.

Principal Accountant Fees and Services

The following table sets forth by category of service the fees incurred in engagements performed by Deloitte & Touche LLP, the member firms of Deloitte Touche Tohmatsu Limited and their respective affiliates, for professional services rendered to the Company for the fiscal years ended December 31, 2023 and December 31, 2022.

	December 31, 2023		December 31, 2022
	(in Thousands)		(in Thousands)
Audit Fees	$	3,059	$	1,465
Audit-Related Fees		—		—
Tax Fees		147		29
All Other Fees		—		—
Total	$	3,206	$	1,494

Audit Fees

Audit fees for the fiscal years ended December 31, 2023 and December 31, 2022 were $3.0 million and $1.5 million, respectively. Such audit fees consist of aggregate fees, including expenses, billed and reasonably expected to be billed by Deloitte & Touche LLP, the member firms of Deloitte Touche Tohmatsu Limited and their respective affiliates in connection with the annual audit and in connection with certain registration statements on Forms S-3 and S-8.

Audit-Related

Tax Fees

Tax fees for the fiscal years ended December 31, 2023 and December 31, 2022 were $146,860 and $28,875. Such tax fees consist of tax advisory services.

All Other Fees

There were no other fees or expenses billed by Deloitte & Touche LLP, the member firms of Deloitte Touche Tohmatsu Limited and their respective affiliates not otherwise described above.

38

Pre-Approval Policies and Procedures

The Audit Committee approves all audit and audit-related services, tax services and other services provided by Deloitte & Touche LLP, the member firms of Deloitte Touche Tohmatsu Limited and their respective affiliates. The Audit Committee approved all services rendered by Deloitte & Touche LLP in the fiscal year ended December 31, 2023, in accordance with these policies.

Any services provided by Deloitte & Touche LLP, the member firms of Deloitte Touche Tohmatsu Limited and their respective affiliates that are not specifically included within the scope of the audit must be pre-approved by the Audit Committee in advance of any engagement. Under the Sarbanes-Oxley Act of 2002, audit committees are permitted to approve certain fees for audit-related services, tax services and other services pursuant to a de minimis exception prior to the completion of an audit engagement. In 2023, none of the fees paid to Deloitte & Touche LLP, the member firms of Deloitte Touche Tohmatsu Limited and their respective affiliates were approved pursuant to the de minimis exception.

In making its recommendation to appoint Deloitte & Touche LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024, the Audit Committee has considered whether the services provided by Deloitte & Touche LLP, the member firms of Deloitte Touche Tohmatsu Limited and their respective affiliates are compatible with maintaining the independence of Deloitte & Touche LLP and has determined that such services do not interfere with that firm’s independence in the conduct of its auditing function.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

Management is responsible for the financial reporting process, including the system of internal controls and for the preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America. The Company’s independent auditors are responsible for auditing those financial statements. The Audit Committee’s responsibility is to monitor and review these processes. We rely, without independent verification, on the information provided to us and on the representations made by management and the independent auditors.

We have reviewed and discussed the audited consolidated financial statements for the twelve months ended December 31, 2023 with management and Deloitte & Touche LLP, the Company’s independent registered public accounting firm.

The Audit Committee discussed and reviewed with Deloitte & Touche LLP all communications required by generally accepted auditing standards, including, among other things, the matters required to be discussed by the Public Company Accounting Oversight Board (“PCAOB”) Auditing Standard No. 16, “Communication with Audit Committees,” and discussed and reviewed the results of Deloitte & Touche LLP’s audit of the Company’s consolidated financial statements. The Audit Committee also discussed the results of internal audit examinations.

The Company’s independent auditors also provided to us the written disclosures and the annual communication required by PCAOB Rule 3526, “Communication with Audit Committees Concerning Independence,” regarding the independent accountant’s communications with the Audit Committee concerning independence, and we discussed with the independent auditors their independence from the Company. When considering Deloitte & Touche LLP’s independence, we considered whether their provision of services to the Company, beyond those rendered in connection with their audit and review of the Company’s consolidated financial statements, was consistent with maintaining their independence. We also reviewed, among other things, the amount of fees paid to Deloitte & Touche LLP, the member firms of Deloitte Touche Tohmatsu Limited, and their respective affiliates for audit and non-audit services.

Based on our review, these meetings, discussions and reports, and subject to the limitations on our role and responsibilities referred to above and in the Audit Committee Charter, we recommended to the Board that the Company’s audited consolidated financial statements for the year ended December 31, 2023 be included in the Company’s Annual Report on Form 10-K.

With respect to the above matters, the Audit Committee submits this report.

Q. What if I have trouble accessing the Annual Meeting?

The virtual Annual Meeting platform is fully supported across MS Edge, Firefox, Chrome and Safari browsers and devices (desktops, laptops, tablets and cell phones) running the most up-to-date version of applicable software and plugins. Please note that Internet Explorer is no longer supported. Participants should ensure that they have a strong WiFi connection wherever they intend to participate in the Annual Meeting. We encourage you to access the Annual Meeting prior to the start time. A link on the meeting page will provide further assistance should you need it or you may call 1-888-724-2416 or 1-781-575-2748 for technical support. Participants should allow plenty of time to log in and to make sure that they can hear streaming audio prior to the start of the Annual Meeting.

Q. Who is entitled to vote at the Annual Meeting?

Stockholders of record at the close of business on March 20, 2024 are entitled to receive notice of and the right to vote at the Annual Meeting. As of the close of business on March 20, 2024, there were 16,726,517 shares of common stock outstanding and entitled to be voted at the Annual Meeting. Each outstanding share of common stock is entitled to one vote. Holders of common stock do not have the right to cumulative voting in the election of directors.

A complete list of stockholders entitled to vote at the Annual Meeting will be available for examination ten days before the Annual Meeting. If you would like to inspect the list of Company stockholders of record, please contact the Investor Relations department at ir@klx.com.

Q. How do you vote your shares?

If you are a stockholder of record, there are four ways to vote:

• Virtually During the Meeting—you may vote online during the virtual Annual Meeting held at www.meetnow.global/M7ZV9LD. To be admitted to the Annual Meeting and vote your shares, you must provide the control number located on your Notice of Internet Availability or Proxy Card;

42

• Internet—visit www.investorvote.com/KLXE and follow the instructions provided on the Notice of Internet Availability or Proxy Card. You must have the control number that is on the Notice of Internet Availability or Proxy Card when voting;

• Telephone—within the U.S. or Canada, call toll-free 1-800-652-8683 and follow the instructions. You must have the control number that is on the Notice of Internet Availability or Proxy Card when voting; or

• Mail—if you have requested a paper copy of the Proxy Materials, complete, sign and date the Proxy Card and return the Proxy Card in the prepaid envelope. Your Proxy Card must be received by the Corporate Secretary of the Company before the voting polls close at the Annual Meeting.

If you vote by Internet or telephone, do not return your Proxy Card. Submitting your proxy by Internet or telephone will not affect your right to vote electronically should you decide to attend and participate in the virtual Annual Meeting. The telephone and Internet voting procedures are designed to authenticate stockholders’ identities, to allow stockholders to give their voting instructions and to confirm that stockholders’ instructions have been recorded properly.

Q. What if you receive more than one Proxy Card or voting instruction form?

This means that you may have more than one account at Computershare, with a nominee or both. Please vote all Proxy Cards and voting instruction forms that you receive so that all the shares that you own will be represented at the Annual Meeting.

Q. What can you do if you change your mind after you submit your proxy?

Your proxy is revocable. If you are a stockholder of record, you can revoke your proxy prior to the completion of voting at the Annual Meeting by:

• delivering an executed, later-dated proxy that is received by the Corporate Secretary of the Company before the voting polls close at the Annual Meeting;

• resubmitting your proxy by Internet or telephone;

• delivering a written notice of revocation of the proxy that is received by the Corporate Secretary of the Company before the voting polls close at the Annual Meeting; or

• voting electronically at the virtual Annual Meeting by following the instructions to vote at www.meetnow.global/M7ZV9LD.

If you are an owner of shares in “street name,” or a beneficial owner, you may submit new voting instructions by contacting your broker, bank or other nominee or by voting online during the Annual Meeting. Voting online during the Annual Meeting will replace any previous votes.

Q. What happens if you do not give specific voting instructions?

All properly executed proxies, unless revoked as described above, will be voted at the Annual Meeting in accordance with your instructions on your proxy. If a properly executed proxy gives no specific instructions, your shares will be voted in the manner recommended by the Board on all matters presented in this Proxy Statement and as the proxy holders may determine in their discretion with respect to any other matters properly presented for a vote at the Annual Meeting.

If you are a beneficial owner of shares in “street name” and do not provide your broker, bank or other nominee with specific voting instructions, your vote will result in a “broker non-vote.”

43

Your broker, bank or other nominee is not permitted to vote on your behalf in the Declassification Amendment (Proposal 1), the election of directors (Proposal 2), the Say-on-Pay Resolution (Proposal 3), the Say-on-Frequency Resolution (Proposal 4), the Bylaw Supermajority Amendment (Proposal 5) or the Charter Supermajority Amendment (Proposal 6). Accordingly, if you do not provide timely voting instructions to your broker, bank or other nominee that holds your shares, your vote will not count. The broker nominee, however, will be able to vote on the ratification of the selection of the Company’s independent auditor (Proposal 7) even if it does not receive your instructions, so no broker non-votes are expected to exist in connection with this proposal.

Q. What proposals will be voted on at the Annual Meeting, and what votes are required to approve each of the proposals?

The required vote for each of the proposals expected to be acted upon at the Annual Meeting and the treatment of abstentions and broker non-votes under each proposal are described below:

Proposal 1—Amendment to the Certificate of Incorporation to declassify Board. The Declassification Amendment must be approved by the affirmative vote of at least 66 2/3% of the voting power of the outstanding voting stock of the Company, voting together as a single class. As a result, abstentions and broker non-votes will have the same effect as a vote “AGAINST” the proposal.

Proposal 2—Election of Class III directors. Directors are elected by a plurality of the voting power of the outstanding shares of the Company that are present in person or represented by proxy and entitled to vote on the election of directors, with the nominees obtaining the most votes being elected. Because there is no minimum vote required, abstentions and broker non-votes will have no effect on the outcome.

Proposal 3—Say-on-Pay Resolution. Stockholders are provided with the opportunity to cast an advisory, non-binding vote on the compensation of the Company’s NEOs. The Say-on-Pay Resolution must be approved by the affirmative vote of the majority of the voting power of the shares present in person or represented by proxy at the annual meeting and entitled to vote on the question. As a result, abstentions will have the same effect as a vote “AGAINST” the proposal. Broker non-votes will not be considered entitled to vote on this proposal and will therefore have no effect on the vote outcome.

Proposal 4—Say-on-Frequency Resolution. Stockholders are also entitled to vote, on an advisory, non-binding basis, as to whether future advisory votes on the Company’s NEO compensation should occur every one, two or three years or to abstain from such voting. The option that receives the most votes will be adopted. As a result, abstentions and broker non-votes will have no effect on the vote outcome.

Proposal 5—Amendment to the Certificate of Incorporation to eliminate the supermajority voting requirements required to amend the Company’s bylaws. The Bylaw Supermajority Amendment must be approved by the affirmative vote of at least 66 2/3% of the voting power of the outstanding voting stock of the Company, voting together as a single class. As a result, abstentions and broker non-votes will have the same effect as a vote “AGAINST” the proposal.

Proposal 6—Amendment to the Certificate of Incorporation to eliminate the supermajority voting requirements required to amend the Company’s certificate of incorporation. The Charter Supermajority Amendment must be approved by the affirmative vote of at least 66 2/3% of the voting power of the outstanding voting stock of the Company, voting together as a single class. As a result, abstentions and broker non-votes will have the same effect as a vote “AGAINST” the proposal.

Proposal 7—Ratification of selection of independent registered public accounting firm. The Auditor Ratification Proposal must be approved by the affirmative vote of the majority of the voting power of the shares present in person or represented by proxy at the annual meeting and entitled to vote on the question. As a result,

44

abstentions will have the same effect as a vote “AGAINST” the proposal. Broker non-votes will not be considered entitled to vote on this proposal and will therefore have no effect on the vote outcome. As discussed above, we do not expect any broker non-votes with respect to this proposal.

Q. What are “broker non-votes,” “withhold” votes, and “abstentions” and their effect on each proposal?

A broker non-vote occurs when a broker, bank, trust or other nominee or custodian holding shares for a beneficial owner in “street name” does not vote the shares on a proposal because the nominee does not have discretionary voting power for a particular item and has not received instructions from the beneficial owner regarding voting.

At the Annual Meeting, your broker nominee will not be able to submit a vote on any matter other than the Auditor Ratification Proposal, unless it receives your specific instructions. If the broker nominee does not receive your specific instructions for the remaining proposals, it will submit a broker non-vote.

Broker non-votes are counted as present and entitled to vote for quorum purposes, but are not considered entitled to vote and will have no effect on the outcome of the Say-on-Pay Resolution (Proposal 3) or the Auditor Ratification Proposal (Proposal 7). However, because the Declassification Amendment (Proposal 1), the Bylaw Supermajority Amendment (Proposal 5) and the Charter Supermajority Amendment (Proposal 6) require the affirmative vote of a minimum threshold of the voting power of the outstanding voting stock of the Company, broker non-votes will have the effect of a vote “AGAINST” these proposals. Because there is no minimum vote required, broker non-votes will have no effect on the outcome of the election of directors (Proposal 2) or the Say-on-Frequency Resolution (Proposal 4).

The broker nominee, however, will be able to vote on the Auditor Ratification Proposal even if it does not receive your instructions, so no broker non-votes are expected to exist in connection with this proposal.

An abstention (i.e., if you or your broker mark “ABSTAIN” on a proxy or voting instruction form, or if a stockholder of record attends the Annual Meeting but does not vote (either before or during the Annual Meeting)) has the same effect as voting “AGAINST” the Declassification Amendment (Proposal 1), the Say-on-Pay Resolution (Proposal 3), the Bylaw Supermajority Amendment (Proposal 5), the Charter Supermajority Amendment (Proposal 6), and the Auditor Ratification Proposal (Proposal 7). Because there is no minimum vote required, abstention has no effect on the outcome of the election of directors (Proposal 2) and the Say-on-Frequency Resolution (Proposal 4).

Votes that are “withheld” from a director’s election will not affect the outcome of the vote on the election of a director, except that if a nominee receives a number of “WITHHOLD” votes that equals or exceeds the number of “FOR” votes, that nominee must submit such director’s offer of resignation to the Chairman of the Board. See “Nomination of Directors” above.

Abstentions and “withhold” votes are counted as present and entitled to vote for purposes of determining a quorum.

Q. How many votes must be present to hold the Annual Meeting?

A quorum is necessary for conducting a valid meeting. Holders of a majority of the outstanding shares of our common stock as of the record date of March 20, 2024 who are entitled to vote must be present, virtually or by proxy, to constitute a quorum at the Annual Meeting. Abstentions, broker non-votes and “withhold” votes will be counted as present and entitled to vote for purposes of determining a quorum.

Q. Will you have a chance to ask questions at the Annual Meeting?

We are aware of concerns that virtual meetings may diminish stockholder voices or reduce accountability and are taking steps to address these concerns. For example, our virtual meeting format enhances, rather than

45

constrains, stockholder access, participation and communication because the online format allows stockholders to communicate with us during the Annual Meeting so they can ask questions to our Board, management and a representative from our independent registered public accounting firm.

We have reserved 15 minutes for stockholder questions at our Annual Meeting. We will answer stockholder questions as they come in, as time permits. We are committed to publicly answering each question received following the Annual Meeting, with the exception of any questions that are irrelevant to the purpose of the Annual Meeting or our business or that contain inappropriate or derogatory references. If we receive substantially similar questions, we will group such questions together and provide a single response to avoid repetition. Please direct any matters of individual concern to ir@klx.com. Although the live webcast is available only to stockholders as of the record date at the time of the Annual Meeting, the webcast of the Annual Meeting will be archived for the public for one year after the date of the Annual Meeting at www.klx.com.

Q. How are proxies being solicited and who pays the solicitation expenses?

Proxies are being solicited by the Board on behalf of the Company. All expenses of the solicitation, including the cost of preparing and mailing this Proxy Statement and Proxy Materials, will be borne by the Company. Proxies may be solicited by our officers, directors and employees personally or by telephone, e-mail or other forms of communication. The Company may also request banks, brokerage firms, custodians, nominees and fiduciaries to forward Proxy Materials to beneficial owners of the Company’s common stock. The costs of the solicitation, including reimbursements of any forwarding expenses, will be paid by the Company.

Q. You share an address with another stockholder. Why did you receive only one copy of the Proxy Materials, and how may you obtain an additional copy of the Proxy Materials?

The SEC has adopted rules that permit companies and intermediaries, such as brokers, to satisfy the delivery requirements for the Proxy Materials with respect to two or more stockholders sharing the same address by delivering a single set of the Proxy Materials addressed to those stockholders. This process, which is commonly referred to as “householding,” is intended to provide extra convenience for stockholders and cost savings to the companies.

A number of brokers with account holders who are stockholders may be “householding” the Company’s Proxy Materials. A single set of Proxy Materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. If you have received notice from your broker that it will be “householding” communications to your address, “householding” will continue until you are notified otherwise, until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate set of materials, please notify your broker or the Company at 3040 Post Oak Boulevard, 15th Floor, Houston, TX 77056, Attn: Corporate Secretary or (832) 844-1015, and the Company will promptly deliver such additional materials to you. Stockholders who have multiple accounts in their names or who share an address with other stockholders can request “householding” and authorize your broker to discontinue mailings of multiple annual reports and Proxy Statements by contacting your broker.

Q. Whom do you call if you have questions about the Annual Meeting?

If you have questions about the Annual Meeting, or desire additional copies of this Proxy Statement or additional proxies, you may contact:

KLX Energy Services Holdings, Inc.

3040 Post Oak Boulevard, 15th Floor

Houston, TX 77056

(832) 844-1015

Attention: Corporate Secretary

46

Q. How will the results of voting be announced?

The Company expects to announce the preliminary voting results at the Annual Meeting. The final voting results will be tallied by the inspector of elections and published in a Current Report on Form 8-K, which the Company is required to file with the SEC within four business days after the Annual Meeting.

47

STOCKHOLDER PROPOSALS

Proposals of stockholders intended to be presented at the 2025 Annual Meeting of Stockholders pursuant to Rule 14a-8 under the Exchange Act must be received by the Corporate Secretary of the Company at its executive offices no later than November 25, 2024, to be considered for inclusion in the Company’s proxy materials for the Annual Meeting.

In addition to satisfying the requirements under the Company’s Fourth Amended and Restated Bylaws described in the immediately preceding paragraph, to comply with the universal proxy rules under the Exchange Act, any stockholder who intends to solicit proxies in support of director nominees other than the Board’s nominees must provide written notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 10, 2025. However, if the date of the 2025 Annual Meeting is more than 30 days before or after the anniversary of the date of the preceding year’s annual meeting of stockholders, then such written notice must be delivered by the later of (x) the 10th day following the public announcement of the date of the 2025 Annual Meeting is first made by the Company and (y)  the date which is 60 days prior to the date of the 2025 Annual Meeting.

OTHER MATTERS

The Board is not aware of any matters that will be brought before the meeting other than as described in this Proxy Statement. However, if any matters properly come before the meeting that are not specifically set forth on the Proxy Card and in this Proxy Statement, the persons designated as proxies will have authority to vote thereon in accordance with their best judgment.

COPIES OF THE COMPANY’S ANNUAL REPORT ON FORM 10-K FILED WITH THE SEC MAY BE OBTAINED WITHOUT CHARGE TO EACH PERSON TO WHOM A NOTICE OF INTERNET AVAILABILITY IS DELIVERED UPON WRITTEN REQUEST ADDRESSED TO 3040 POST OAK BOULEVARD, 15TH FLOOR, HOUSTON, TX 77056, ATTN: CORPORATE SECRETARY.

APPENDIX A

Reconciliation of Consolidated Net Income to Adjusted EBITDA

Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. Adjusted EBITDA is not a measure of net earnings or cash flows as determined by GAAP. We define Adjusted EBITDA as net earnings (loss) before interest, taxes, depreciation and amortization, further adjusted for (i) goodwill and/or long-lived asset impairment charges, (ii) stock-based compensation expense, (iii) restructuring charges, (iv) transaction and integration costs related to acquisitions and (v) other expenses or charges to exclude certain items that we believe are not reflective of ongoing performance of our business. Adjusted EBITDA is used to calculate the Company’s leverage ratio, consistent with the terms of the Company’s asset-based lending facility.

We believe Adjusted EBITDA is useful because it allows us to supplement the GAAP measures in order to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure. We exclude the items listed above in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP, or as an indicator of our operating performance or liquidity. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDA. Our computations of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies.

The following tables present a reconciliation of Adjusted EBITDA to Consolidated net loss, the most directly comparable GAAP financial measure, for the periods indicated:

(Unaudited – In millions of U.S. dollars)

APPENDIX B

Amendment to Amended and Restated Certificate of Incorporation

Additions to the Amended and Restated Certificate of Incorporation pursuant the Declassification Amendment contemplated by Proposal 1 are indicated below by bold, underlined text and deletions contemplated thereby are indicated below by strike-out text. The full text of the Company’s currently applicable Amended and Restated Certificate of Incorporation was filed as an exhibit to the Company’s Quarterly Report on Form 10-K filed with the SEC on September 8, 2020.

The proposed Declassification Amendment changes to Article V are set forth below:

(3) The Until the election of directors at the 2026 annual meeting of stockholders, the Board shall be divided into three classes (each such class, a “Class”), as nearly equal in number as possible, designated: Class I, Class II and Class III. As soon as practicable following the effectiveness of this Certificate of Incorporation, and thereafter from time to time following any increase or decrease in the number of directors, the number of directors in each Class shall be apportioned by the Board to be as nearly equal as possible. No decrease in the number of directors shall shorten the term of any incumbent director. Commencing with the election of directors at the 2024 annual meeting of stockholders, the directors of the Class whose terms expire at such annual meeting shall be elected for a one-year term ending at the next annual meeting of stockholders. Commencing with the election of directors at the 2026 annual meeting of stockholders and for each annual meeting of stockholders thereafter, the Board shall no longer be classified and all of the directors shall be elected annually for a term expiring at the next annual meeting of stockholders.

(4) Each director shall hold office until the end of the term provided for such director in paragraph (53) or (86) of this Article V, and thereafter until such director’s successor is elected and qualified, or until such director’s earlier death, resignation or removal in the manner hereinafter provided.

(5) Except as provided in paragraph (8) of this Article V, each director shall serve for a term ending on the date of the third annual meeting following the annual meeting at which such director was elected; provided, however, that each director initially appointed as a Class I director shall serve for an initial term expiring at the Corporation’s first annual meeting of stockholders following the effectiveness of this Certificate of Incorporation; each director initially appointed as a Class II director shall serve for an initial term expiring at the Corporation’s second annual meeting of stockholders following the effectiveness of this Certificate of Incorporation; and each director initially appointed as a Class III director shall serve for an initial term expiring at the Corporation’s third annual meeting of stockholders following the effectiveness of this Certificate of Incorporation.

(56) Any director or the entire Board may be removed from office only for with or without cause and only by upon the affirmative vote of at least sixty-six and two-thirds percent (66 2/3%) a majority of the total voting power of the outstanding shares of the capital then-outstanding voting stock of the Corporation entitled to vote in any annual election of directors or Class of directors, voting together as a single class.

(7) Vacancies occurring on the Board for any reason, including, without limitation, vacancies occurring as a result of the death, resignation, retirement, disqualification or removal from office of a director, or the creation of new directorships that increase the number of directors, shall solely be filled by a majority vote of the directors then in office, even if the number of such directors is less than a quorum, or by a sole remaining director, or by the written consent of such directors as permitted by the General Corporation Law and as provided in the Bylaws of the Corporation, and shall not be filled by the stockholders.

(8) Any director chosen to fill a vacancy pursuant to paragraph (7) of this Article V shall, at the time such director is chosen or as soon as practicable thereafter, be designated by the Board as either a Class I, Class II or Class III director, with such Class corresponding to the Class in which such vacancy existed. Such director shall

B-1

serve for a term equal to the remainder of the term of the other directors of such Class in office at the time such vacancy was filled (or, if no other directors are a member of such Class at such time, for a term equal to the remainder of the term that a director of such Class would have served had such director been in office at the time of the effectiveness of this Certificate of Incorporation and served continuously as a director until the time that such vacancy was filled).

(6) Any director chosen to fill a vacancy pursuant to paragraph (5) of this Article V, shall serve for a term expiring at the next annual meeting of stockholders.

(79) At any meeting of stockholders at which directors are elected, directors shall be elected by a plurality of the voting power of the shares entitled to vote on the election of directors and present in person or by proxy at the meeting. Elections of directors of the Corporation need not be by written ballot, except and to the extent provided in the Bylaws of the Corporation.

(811) Nothing in this Article V shall be deemed to affect or restrict (i) any rights of the holders of any series of Preferred Stock to elect directors as provided for or fixed pursuant to the provisions of Article IV, or (ii) the ability of the Board to provide, pursuant to Article IV, for the preferences and relative, participating, optional or other special rights, if any, and any qualifications, limitations or restrictions thereof, of the shares of any series of Preferred Stock, including with regard to those directors, if any, to be elected by the holders of any series of Preferred Stock.
