**Online Meeting**

We will conduct the Annual Meeting solely online via the internet through a live webcast and online stockholder tools. We believe a virtual format facilitates stockholder attendance and participation by leveraging technology to allow us to communicate more effectively and efficiently with our stockholders. This format empowers stockholders around the world to participate at no cost. We have designed the virtual format to enhance stockholder access and participation and protect stockholder rights.

**We Encourage Questions.** Stockholders may submit a question live during the meeting, following the instructions below. During the meeting, we will answer as many appropriate stockholder-submitted questions as time permits. 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 constrains, stockholder access, participation

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.

**Our Compensation Philosophy**

The Company's philosophy regarding the executive compensation program for our Named Executive Officers (together referred to as the "NEOs" or "Named Executive Officers" throughout) and other senior managers has been to design a compensation package that provides competitive base salary levels and compensation incentives that (i) attract and retain individuals of outstanding ability in these key positions, (ii) recognize corporate performance relative to established goals and the performance of the Company relative to the performance of other companies of comparable size, complexity and quality and against budget goals, and (iii) support both the short-term and long-term strategic goals of the Company. The Company's compensation programs are designed to provide compensation that:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;Attracts, motivates, rewards and retains high-performing executives | ![icon_plus_icon_plus.jpg](ois-20260326_g35.jpg) | Reinforces the relationship between strong individual performance of executives and business results | ![icon_plus_icon_plus.jpg](ois-20260326_g35.jpg) | Aligns the interests of our executives with the long-term interests of our stockholders | ![icon_plus_icon_plus.jpg](ois-20260326_g35.jpg) | Neither promotes overly conservative actions or excessive risk taking |

---

In order to further its pay-for-performance goal, the Compensation Committee has determined it appropriate to deliver a significant portion of executive compensation as at risk compensation, including both short- and long-term incentives. The following charts depict elements of the target compensation for the Chief Executive Officer and collectively for the other Named Executive Officers of the Company.

**Proxy Summary**

**Reported versus Actual Paid Values of Executive Compensation**

The Compensation Committee is committed to targeting reasonable and competitive compensation for the Named Executive Officers. Because a significant portion of the Named Executive Officers' compensation is at risk, the target values established at the date of award may vary substantially from the values actually paid from year-to-year, particularly given the highly cyclical nature of the energy services industry.

"Reported compensation" is the total compensation that is reported in the Summary Compensation Table of our Proxy Statement which reflects equity awards at grant date values. As further described and detailed under "Pay versus Performance" beginning on page [61](#ia8b1ed578b074cfc81fcbf6bb9b970dc_115), "actual compensation paid" values presented in the tables below were determined in accordance with the requirements of Item 402(v) of Regulation S-K, which requires the Company to make certain adjustments to equity compensation amounts reported in the Summary Compensation Table (including unrealized gains (losses) during the year on unvested equity awards) in an effort to more closely reflect amounts actually earned by the Named Executive Officers.

The following table summarizes "reported compensation" values for our Chief Executive Officer and collective average for the other Named Executive Officers, as compared to "actual compensation paid" values for the years ended December 31, 2021, 2022, 2023, 2024 and 2025 (in thousands):

As discussed above, "compensation actually paid" includes Securities and Exchange Commission (the "SEC") required adjustments for unrealized gains and losses on unvested equity awards during the year.

**ITEM 1:**

**Election of Directors**

The Board of Directors is currently comprised of seven members. The seven members are divided into three classes currently having two members in each of Class I and II, and three members in Class III. Each class is elected for a term of three years, so that the term of one class of directors expires at each Annual Meeting of Stockholders.

The term of the two current Class I directors will expire at the Annual Meeting. The term of the Class II directors will expire at the 2027 Annual Meeting of Stockholders and the term of the Class III directors will expire at the 2028 Annual Meeting of Stockholders.

**Nominees**

Lawrence R. Dickerson and Cindy B. Taylor, presently serve as Class I directors. Ms. C. Taylor will be retiring from the Board on May 1, 2026. The Board thanks Ms. C. Taylor for her 19 years of service. The Board of Directors has nominated Lawrence R. Dickerson and Lloyd A. Hajdik to fill the expiring Class I positions on the Board of Directors, to hold office for three-year terms expiring at the Annual Meeting of Stockholders in 2029, or until his successor has been duly elected and qualified, or until his or her earlier death, resignation or removal. Stockholder nominations will not be accepted for filling Board of Directors seats at the Annual Meeting because our bylaws require advance notice

for such a nomination, the time for which has passed. Our Board of Directors has determined that Lawrence R. Dickerson is "independent" as that term is defined by the applicable New York Stock Exchange (the "NYSE") listing standards. See "Director Independence" below for a discussion of director independence determinations. The Board of Directors recommends that stockholders vote "FOR" the election of Lawrence R. Dickerson and Lloyd A. Hajdik as Class I directors.

There are no family relationships among executive officers and/or the directors of the Company.

**Vote Required**

A plurality of votes of the shares present in person or represented by proxy cast at the Annual Meeting and entitled to vote on the election of directors is required for the election of directors. You may vote for all the nominees, withhold authority to vote your shares for all the nominees or withhold authority to vote your shares with respect to any one or more of the nominees. A ballot for a nominee that is marked "withheld" will not be counted as a vote cast.

Broker non-votes will not have any effect on the outcome of voting on director elections. If any nominee should be unable to serve as a director, the shares represented by proxies will be voted for the election of a substitute nominated by the Board of Directors to replace such nominee, or the Board of Directors may reduce the size of the Board, at its discretion.

**Director Resignation Policy**

Our Corporate Governance Guidelines provide that in an uncontested election, any nominee for director who receives a greater number of votes "withheld" from his or her election than votes "for" such election (a "Majority Withheld Vote") shall promptly tender his or her resignation for consideration by the Nominating, Governance and Sustainability Committee following certification of the stockholder vote.

The Nominating, Governance and Sustainability Committee shall promptly consider the resignation offer and make a recommendation to the Board of Directors as to whether the resignation should be accepted. In making this recommendation, the Nominating, Governance and Sustainability Committee will consider all factors deemed relevant by its members including, without limitation: (1) the underlying reasons why stockholders may have "withheld" votes for election from such director, if known; (2) the length of service and qualifications of the director whose resignation has been tendered; (3) the director's past and potential future contributions to the Company; (4) the current mix of skills and attributes of directors on the Board; (5) whether, by accepting the resignation, the Company will no longer be in compliance with any applicable law, rule, regulation, or governing instrument; and (6) whether accepting the resignation would be in the best interests of the Company and its stockholders. Thereafter, the Board will promptly disclose the material findings of its decision-making process and its decision as to whether to accept the director's resignation offer (or, if applicable, the reason(s) for rejecting the resignation offer) in a Form 8-K furnished to the SEC.

**Corporate Governance**

**Corporate Governance Guidelines**

The Company has adopted corporate governance guidelines entitled "Corporate Governance Guidelines," which are available at www.oilstatesintl.com by first clicking "Corporate Governance" and then "Corporate Governance Guidelines." These guidelines were adopted by the Board of Directors so that the Board of Directors has the necessary

authority and practices in place to make decisions that are independent from management, that the Board of Directors adequately performs its function as the overseer of management and to help ensure that the interests of the Board of Directors and management are aligned with the interests of the Company's stockholders.

**Selecting Our Directors**

Our director nomination process for new Board of Directors members is as follows:

• The Nominating, Governance and Sustainability Committee, the Chair of the Board, or another member of the Board identifies a need to add a new Board member who meets specific criteria or to fill a vacancy on the Board of Directors.

• The Nominating, Governance and Sustainability Committee initiates a search by working with staff support, seeking input from members of the Board and senior management or hiring a search firm, if deemed necessary, and endeavors to find an initial pool of qualified candidates that includes (but need not be limited to) persons that are diverse in viewpoints, backgrounds, education and business experience.

• The Nominating, Governance and Sustainability Committee considers candidate recommendations properly submitted by stockholders using the same criteria it applies to evaluate other candidates, consistent with the Board's practices and policies.

• The initial slate of candidates that will satisfy specific criteria and otherwise qualify for membership on the Board of Directors is identified and presented to the Nominating, Governance and Sustainability Committee.

• The Chair of the Board and at least one member of the Nominating, Governance and Sustainability Committee interview prospective candidate(s).

• The full Board of Directors is kept informed of progress.

• The Nominating, Governance and Sustainability Committee offers other directors the opportunity to interview the candidate(s) and then meets to consider and approve the final candidate(s).

• The Nominating, Governance and Sustainability Committee seeks the endorsement of the Board of Directors of the final candidate(s).

• The final candidate(s) are nominated by the Board of Directors or appointed to fill a vacancy (including a vacancy that results from the Board of Directors expanding the size of the Board).

To submit a candidate recommendation to the Nominating, Governance and Sustainability Committee, a stockholder should send a written request, as discussed below, to the attention of the Company's Secretary at Oil States International, Inc., Three Allen Center, 333 Clay Street, Suite 4620, Houston, Texas 77002. A stockholder may make a nomination for election to our Board of Directors for the 2027 Annual Meeting of Stockholders by delivering proper notice to our Secretary at least 120 days prior to the first anniversary date of the 2026 Annual Meeting as more fully described below under Nominating, Governance and Sustainability Committee.

• the person's reputation and integrity;

• the person's qualifications to serve as an independent, disinterested, and non-employee or outside director;

• the number of other public companies for which the person serves as a director and the availability of the person's time and commitment to the Company; and

(1)Data is as of May 1, 2026 and gives effect to Ms. C. Taylor's retirement and Mr. Hajdik's appointment to President and Chief Executive Officer.

In selecting nominees for the Board of Directors, the Nominating, Governance and Sustainability Committee considers, among other things, educational background, business and industry experience, diversity of viewpoints and knowledge of different geographic markets and oilfield services and products.

**Corporate Governance**

**Director Independence**

To qualify as "independent" under the NYSE listing standards, a director must meet objective criteria set forth in the NYSE listing standards, and the Board of Directors must affirmatively determine that the director has no material relationship with us (either directly or as a partner, stockholder or officer of an organization that has a relationship with us).

The Board of Directors reviews all direct or indirect business relationships between each director (including his or her immediate family) and our Company, as well as each director's relationships with charitable organizations, to assess director independence as defined in the listing standards of the NYSE. The NYSE listing standards include a series of objective tests to determine independence, such as whether the director is an employee of our Company or has engaged in various types of business dealings, directly or indirectly, with our Company.

In addition, as further required by the NYSE, the Board of Directors has made a subjective determination as to each independent director that no material relationships exist between each such director and the Company, considering a number of factors including the nature of any personal friendships or relationships among Directors and members of management. When assessing the materiality of a director's relationship with us, the Board of Directors considers the issue not merely from the standpoint of the director, but also from the standpoint of the persons or organizations with which the director has an affiliation.

The Board of Directors has determined that Messrs. Potter, Dickerson, Hollek and Wright and Mses. Castillo-Rhodes and Vanderhider qualify as "independent" in accordance with NYSE listing standards. Ms. C. Taylor, our President and Chief Executive Officer, is currently the only non-independent director. Upon his appointment to the Board of Directors and as President and Chief Executive Officer, Mr. Hajdik will become the only non-independent director.

**Role and Responsibilities of the Board**

**Board of Directors Oversight of Enterprise Risk**

Risk oversight is a responsibility of the Board of Directors. The Board of Directors utilizes an Enterprise Risk Management ("ERM") process to assist in fulfilling its oversight responsibilities.

Management and all employees are responsible for day-to-day risk management. Each year, management conducts a comprehensive risk assessment of Oil States' business. The risk assessment process is global in nature and is focused on four main areas: strategic risks (both internal and external); compliance risks; information technology risks; and operational risks. Information relevant to this risk assessment is obtained through surveys and/or interviews of key executives, business segment leaders, and other managers. Our ERM process is designed to identify and assess the Company's most significant risks (over the short-, medium- and long-term) in these areas, including: the potential magnitude of the risk; likelihood of the risk occurring; and the speed with which the risk could impact the Company; as well as to identify steps to mitigate and manage each significant risk. The results of the risk

assessment are reviewed on an annual basis with the Board of Directors and are integral to the Board of Directors and its committees' deliberations.

The Board of Directors has delegated responsibility for overseeing certain enterprise risks to its standing committees. The Audit Committee oversees the monitoring and assessment of risks related to financial reporting, related compliance matters and cybersecurity. The Compensation Committee is responsible for overseeing the review and assessment of risks related to the Company's compensation policies and programs to enhance the correlation of executive pay and performance objectives, and to maintain alignment of interests between executive management and the Company's stockholders. The Nominating, Governance and Sustainability Committee is responsible for overseeing risks related to the Company's corporate governance policies, and environmental (including climate-related risks and corporate responsibility and sustainability activities and practices. Strategical operational risks are handled by the full Board.

**Executive & Director Stock Ownership and Retention Guidelines**

We have executive and director stock ownership guidelines, designed to align executive and director interests with stockholder interests. For a description of the guidelines applicable to our executive officers and directors, see "Compensation Discussion and Analysis – Executive Stock Ownership and Retention Guidelines."

**Securities Trading Policy**

The Company has a securities trading policy ("Securities Trading Policy") governing transactions in the Company's securities that applies to directors, officers and employees, and the Company's policy is to comply with applicable securities laws when transacting in its own securities. We believe our Securities Trading Policy and the Company's policy are reasonably designed to promote compliance with

---

| | |
|:---|:---|
| **24** | 2026 Proxy Statement |

---

------

**Corporate Governance**

insider trading laws, rules and regulations, and the listing standards applicable to the Company. A copy of the Securities Trading Policy was filed as Exhibit 19.1 to the Company's Annual Report on Form 10-K for the year ended December 31, 2024. For a description of our Insider Trading Policy, see "Compensation Discussion and Analysis – Securities Trading Policy."

**Anti-Hedging and Pledging Policies**

Our directors and officers are prohibited from purchasing financial instruments designed to hedge or offset against a decrease in the market value of the Company's stock, holding Company stock in margin accounts, or pledging Company securities as collateral for loans. These prohibitions apply to any Company equity held directly or indirectly (including equity granted as compensation or otherwise held) by directors, and by executives and management personnel who are in charge of business segments, divisions or key functions (such as operations, sales, administration, finance or accounting), and any other officer performing policy-making functions. Our anti-hedging policy does not address employees other than such officers, and does not directly address the designees of directors, officers or employees. While no categories of hedging are specifically permitted for directors and officers, our policy does not specifically address prepaid variable forward contracts, equity swaps, collars or exchange funds, however entry into any of these would, in practice, be considered entry into a hedging transaction under our policy, and therefore would be prohibited.

**Incentive Compensation Recoupment Policy for Named Executive Officers**

In October 2023, the Company's Board of Directors adopted an incentive-based compensation recoupment policy (the "Recoupment Policy") covering its Named Executive Officers responsive to SEC required changes in NYSE listing standards. The policy provides the Company with the ability to seek recoupment of any performance-based compensation received by a Named Executive Officer on or after October 2, 2023 if the Company is required to restate its financial statements due to a material misstatement. For periods prior to October 2023, our Named Executive Officers were subject to the Company's incentive compensation clawback policy described below.

**Supplemental Incentive Compensation Clawback Policy** 

The Company adopted its original incentive compensation clawback policy in 2017. The policy provides the Company with the ability, in appropriate circumstances, to seek restitution of any performance-based compensation received by an employee (including Named Executive Officers) as a result of such employee's fraud or misconduct, resulting in a material misstatement contained in the Company's financial statements, which results in a restatement of these financial statements. In October 2023, we adopted a new incentive compensation clawback policy to comply with new clawback laws (described above); therefore, our original policy was amended and restated to apply more generally to our employee population that may receive incentive compensation awards. However, with respect to any officer covered by the Recoupment Policy described above, to the extent that the Recoupment Policy and our original policy conflict or potentially cover the same event, we will apply the terms of the Recoupment Policy.

**Corporate Code of Business Conduct and Ethics**

All directors, officers and employees of the Company must act ethically at all times and in accordance with the policies comprising the Company's ethics policy entitled "Corporate Code of Business Conduct and Ethics" ("Business Conduct and Ethics Code"). This policy is available on the Company's web site at www.oilstatesintl.com by first clicking "Corporate Governance" and then "Corporate Code of Business Conduct and Ethics."

Ethical principles set forth in this policy include, among other principles, matters such as:

• Acting ethically with honesty and integrity

• Avoiding conflicts of interest

• Complying with disclosure and reporting obligations with full, fair, accurate, timely and understandable disclosures

• Complying with applicable laws, rules and regulations

• Acting in good faith

• Promoting honest and ethical behavior by others

• Respecting confidentiality of information

• Responsibly using and maintaining assets and resources

Employees are required to complete online training on a regular basis which includes a review of the Business Conduct and Ethics Code and an acknowledgement that the employee has read and understands the policy. The Company has a Compliance Committee composed of key employees that meet quarterly to assess efforts and processes to ensure compliance with laws and regulations to which the Company is subject.

The Company's Financial Code of Ethics for Senior Officers applies to the Chief Executive Officer, Chief Financial Officer, principal accounting officer, and other senior accounting and financial officers ("Senior Officers").

Senior Officers must also comply with the Business Conduct and Ethics Code. Each of these policies are available for review on the Company's website at www.oilstatesintl.com. We intend to disclose amendments to and waivers, if any, to each of these policies, as required, on our website promptly following the date of any such amendment or waiver, but in no event later than four business days following such waiver or amendment

**The Board's Role in Stockholder Engagement**

Stockholders or other interested parties may send communications, directly and confidentially, to the Board of Directors, to any committee of the Board of Directors, to non-management directors or to any director in particular by sending an envelope marked "confidential" to suchperson or persons c/o Oil States International, Inc., Three Allen Center, 333 Clay Street, Suite 4620, Houston, Texas 77002. Any such correspondence will be forwarded by the Secretary of the Company to the addressee without review by management.

**Policies and Procedures with Respect to Related Person Transactions and Conflicts of Interest and Related Person and Party Disclosures**

**Related Person Transaction Policies and Procedures**

Pursuant to our written policy, we review all relationships and transactions in which we and any Company director, executive officer or stockholder holding more than 5% of our common stock, or any immediate family member of any such person, is a participant to determine whether any such person has a direct or indirect material interest. Our Corporate Secretary's office is primarily responsible for the development and implementation of processes and controls to obtain information from the directors and executive officers with respect to related person transactions and for then determining, based on the facts and circumstances, whether we or a related person has a direct or indirect material interest in the transaction.

We annually distribute a questionnaire to our executive officers and members of our Board of Directors requesting certain information regarding, among other things, their immediate family members, employment and beneficial ownership interests. This information is then reviewed for materiality and for potential related person transactions.

Additionally, the charter of our Nominating, Governance and Sustainability Committee requires that the members of such committee assess the independence of the non-management directors at least annually, including a requirement that it determine whether or not any such directors have a material relationship with us, either directly or indirectly, as defined therein and as further described above under "Director Independence." Further, on an annual basis our Board of Directors assesses the independence of the non-management directors, including the nature of any personal friendships or relationships among directors and members of management.

As required under the rules of the SEC, transactions in which we are a participant and in which a related person has a direct or indirect material interest, to the extent any exist, are disclosed in our Proxy Statement.

All material related person transactions must be reviewed, evaluated or ratified by the Audit Committee of our Board of Directors. Any member of the Audit Committee who is a related person with respect to a transaction is recused from the review of the transaction.

**Conflict of Interest Policies and Procedures**

Our Business Conduct and Ethics Code prohibits conflicts of interest, except under guidelines approved by the Board of Directors. Under the Business Conduct and Ethics Code, conflicts of interest occur when private, commercial or financial interests interfere in any way, or even appear to interfere, with the interests of our Company. Our prohibition on conflicts of interest under the Business Conduct and Ethics Code includes transactions where a member of a director's or an employee's family or household, receives improper personal benefits as a result of the director's or the employee's position in the Company. Any waivers of these guidelines must be approved by the Nominating, Governance and Sustainability Committee or the Board.

**Related Person and Party Disclosure**

Moses, Executive Vice President and Chief Operating Officer of the Company) was employed by a subsidiary of the Company as a Group Vice President during 2025. This individual is employed on an "at will" basis and compensated on the same basis as our other employees of similar function, seniority and responsibility without regard to his relationship with Philip S. Moses. This individual, who does not reside with and is not supported financially by Mr. Moses, received compensation for services rendered in the above capacity totaling $447,049 during 2025.

The Chair of the Board and Chief Executive Officer roles have been split with the Chair of the Board role being filled by a non-executive member of the Board of Directors since the Company's initial public offering in 2001. We believe the separation of these two positions leads to a strong independent leadership structure.

**Board and Committee Self-Evaluation**

As required by our Corporate Governance Guidelines, our Board of Directors conducts an annual self-evaluation to determine whether it and its committees are functioning effectively. In accordance with its charter, the Nominating, Governance and Sustainability Committee oversees the annual evaluations, solicits comments from all directors and reports annually to the Board of Directors with an assessment of the performance of the Board and its committees. This assessment is then discussed by the full Board of Directors in executive session in its consideration of any appropriate action or response that might strengthen director communications and the overall effectiveness of the Board of Directors and committee meetings.

**Executive Sessions of the Board**

Our Corporate Governance Guidelines provide that our non-employee directors shall meet separately in executive session at least annually. The director who presides at these sessions is the Chair of the Board, assuming such person is a non-management director. Otherwise, the presiding director will be chosen by a vote of the non-management directors. In addition to the executive

sessions of our non-management directors, our independent directors (as defined in the applicable NYSE listing standards) are required to meet in executive session at least annually without the presence of management. In 2025, our independent directors met in executive session four times. Our Chair of the Board, Mr. Potter, who is an independent director, presided at these sessions.

**Committees**

**Board Composition**

The Board of Directors has established three standing committees: the Audit Committee, the Compensation Committee and the Nominating, Governance and Sustainability Committee.Below is a summary of our committee structure and membership information as of March 31, 2026.

**Board and Committee Meetings; Attendance**

**Number of Meetings in 2025**

![barchart_boardandcommitteemeetingsattendance.jpg](ois-20260326_g67.jpg)

Each of the incumbent directors attended at least 89% of the aggregate number of meetings of the Board of Directors and the committees of the Board of Directors on which they served in 2025.

While we understand that scheduling conflicts may arise, we expect directors to make reasonable efforts to attend the Annual Meeting of Stockholders and all meetings of the Board of Directors and the committees on which they serve. In 2025, each of the directors attended the Annual Meeting of Stockholders.

**Director Compensation**

We compensate each non-employee director for service on the Board of Directors. The Compensation Committee reviews director compensation on an annual basis. No changes to the director compensation program were made in 2025.

Non-employee director compensation (paid quarterly, except for the annual equity award) for 2025 was:

---

| | |
|:---|:---|
| **2025 COMPENSATION ELEMENTS** | **AMOUNT<br>($)** |
| Annual Retainer | 60000 |
| Attendance Fee for each Board and Committee Meeting | 2000 |
| Chair of the Board Annual Retainer (paid 50% in cash and 50% in fully-vested shares of Company common stock) | 100000 |
| Annual Retainer: <br>Audit Committee Chair | 20000 |
| Audit Committee Member | 10000 |
| Annual Retainer: <br>Compensation Committee Chair | 15000 |

| Annual Retainer: <br>Nominating, Governance and Sustainability Committee Chair | 15000 |
| Nominating, Governance and Sustainability Committee Member | 5000 |
| Annual Equity Award (approximate value on date of grant) | 150000 |

---

To align the non-employee directors' compensation with the financial interests of our stockholders, a significant portion of their compensation is generally paid in the form of restricted stock or deferred stock unit awards.

Newly elected or appointed non-employee directors receive restricted stock awards of the Company's common stock valued at approximately $150,000 after their initial election or appointment. Non-employee directors generally receive additional restricted stock or deferred stock unit awards valued at approximately $150,000 at each annual meeting of stockholders after which they continue to serve. The non-employee directors' restricted stock and deferred stock unit awards vest on the earlier of one year from the date of grant or the date of the next Annual Meeting of Stockholders. Upon vesting, restricted stock is released to the director. If a director elects to defer the issuance of common stock related to the restricted deferred stock unit

award to a specified future date, the underlying common stock is not issued to the director until such date.

All outstanding restricted stock and deferred stock units held by non-employee directors will fully vest in the event of a "Change of Control."

Non-employee directors are subject to the Company's stock ownership and retention guidelines pursuant to which they are expected to retain restricted stock or deferred stock unit award shares, remaining after payment of applicable taxes, valued at five times the annual board retainer amount until retirement or until leaving the Board of Directors. Directors are required to achieve their required ownership within five years from inclusion in the program and continue to maintain and hold the level of stock ownership as long as they are directors of the Company. All directors were in compliance with the ownership guidelines as of December 31, 2025.

**Corporate Governance**

Stock that counts toward satisfaction of the stock ownership and retention guidelines includes:

• Company shares owned outright (i.e. open market purchases) by the director or his or her immediate family members residing in the same household;

• Shares owned indirectly by the director (e.g., by a spouse or other immediate family member or a trust for the benefit of the director or his or her family), whether held individually or jointly; and

• Time-based restricted stock and deferred stock units granted to the director under the Company's long-term equity incentive plan.

All of our directors are reimbursed for reasonable out-of-pocket expenses incurred in attending meetings of our Board of Directors or committees and for other reasonable expenses related to the performance of their duties as directors, including attendance at pertinent continuing education programs and training.

The Company maintains a nonqualified deferred compensation plan (the "Deferred Compensation Plan") that permits eligible employees and directors to elect to defer all or a part of their cash compensation (base and/or incentives) from the Company until the termination of their status as an employee or director, or in the event of a change of control. Directors who elect to participate in the Deferred Compensation Plan do not receive any matching contributions. Additional details regarding the Deferred Compensation Plan are contained within the sections below titled "Deferred Compensation" and "Nonqualified Deferred Compensation."

The table below summarizes the compensation paid by the Company to non-employee directors for the year ended December 31, 2025. Ms. C. Taylor, who served as a member of our Board of Directors during 2025, did not receive any additional compensation for her service on the Board. All compensation provided to Ms. C. Taylor with respect to the 2025 year is reflected in the Summary Compensation Table on page [51](#ia8b1ed578b074cfc81fcbf6bb9b970dc_97).

**ITEM 2:**

**Advisory Vote on Executive Compensation**

The Company is asking that you vote for approval of the compensation of our Named Executive Officers as disclosed in this Proxy Statement.

Section 14A of the Exchange Act requires us to hold an advisory stockholder vote, at least every three years, to approve the compensation of our Named Executive Officers, as such compensation is disclosed pursuant to the disclosure rules of the SEC. In accordance with the vote of the Company's stockholders at the Company's 2023 Annual Meeting of Stockholders regarding the frequency of future advisory votes on the compensation of our Named Executive Officers, the Company currently provides stockholders with this opportunity annually, and plans to continue to do so until next advisory vote regarding the frequency of future advisory votes on the compensation of our Named Executive Officers, which is expected to occur at the 2029 Annual Meeting of Stockholders. Accordingly, we are providing our stockholders with the opportunity to cast an advisory vote on the compensation of our Named Executive Officers as disclosed in this Proxy Statement, under "Compensation Discussion and Analysis."

As discussed in greater detail in the "Compensation Discussion and Analysis," the Company's executive compensation programs are designed to:

• Attract, motivate, reward and retain key employees and executive talent required to achieve corporate strategic plans;

• Reinforce the relationship between strong individual performance of executives and business results;

• Align the interests of executives with the long-term interests of stockholders; and

• Provide a compensation program that neither promotes overly conservative actions or excessive risk taking.

Our compensation program is also designed to reward executives for long-term strategic management and the enhancement of stockholder value. The Compensation Committee believes this approach closely links the compensation of the Company's executives to the execution of the Company's strategy and the accomplishment of Company goals that coincide with stockholder objectives.

For the reasons expressed above, the Compensation Committee and the Board of Directors believe that these compensation policies and practices are aligned with the interests of our stockholders.

We are therefore requesting your non-binding vote on the following resolution:

"RESOLVED, that the compensation paid to the Company's Named Executive Officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion is hereby APPROVED."

**Vote Required**

Approval requires the affirmative vote of a 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 matter. For purposes of the advisory vote on executive compensation, broker non-votes are not countedas votes with respect to the proposal and, therefore, will not affect the outcome of the vote on this proposal, and abstentions will have the same effect as a vote against the proposal.

*Note*: The Company is providing this advisory vote as required pursuant to Section 14A of the Exchange Act. The stockholder vote will not be binding on the Company, the Board of Directors or the Compensation Committee, and it will not be construed as overruling any decision by the Company, the Board of Directors or the CompensationCommittee or creating or implying any change to, or additional, fiduciary duties for the Company, the Board of Directors or the Compensation Committee. Nevertheless, the Compensation Committee will consider the outcome of the vote when evaluating the Company's future compensation practices.

**Compensation Discussion and Analysis**

**Executive Summary**

This Compensation Discussion and Analysis ("CD&A") summarizes the Company's 2025 compensation programs, actions and results relative to the Company's 2025 performance. These outcomes considered the Company's short-term financial and operating achievements measured against plan objectives, cumulative EBITDA performance and stock price performance on a relative basis through the end of 2025. This CD&A provides information about the compensation objectives and policies for our principal executive officer, our principal financial officer and our two other executive officers (collectively our "Named Executive Officers") during the last completed fiscal year, and is intended to place in perspective the information contained in the executive compensation tables that follow this discussion.

**Accomplishments and Priorities**

Our 2025 results of operations reflect management's decision to exit certain underperforming service offerings in the United States as well as the effect of reduced spending by customers operating in the United States in response to lower crude oil prices, competitive market conditions and increased U.S. tariffs on imported goods. Partially offsetting these trends were stronger offshore and international project activity, supported by backlog growth. Despite weaker market conditions and higher tariffs, the Oil States team expanded returns and grew Adjusted EBITDA by 8% to $83 million in 2025 through its restructuring efforts — albeit coming in below the Company's budget set at the beginning of 2025.

**Compensation Discussion and Analysis**

Oil States executed numerous business priorities which should also benefit future earnings:

• **Grew international project-related business within our Offshore Manufactured Products segment –** Project-driven revenues totaled $391 million, an increase of 9% from 2024. Overall segment bookings totaled $554 million in 2025, yielding a book-to-bill ratio of 1.3x. Backlog totaled $435 million as of December 31, 2025, an increase of 40% from December 31, 2024, and the highest level since March 2015.

• **Optimized our U.S. Land-Focused Operations –** Exited underperforming U.S. land-based operations and product lines in 2025 to improve returns. The strategic decision to optimize our Completion and Production Services segment operations drove a year-over-year decline in revenues but improved Adjusted EBITDA margins over the year — with margins increasing from 12% in the fourth quarter of 2024 to 32% in the fourth quarter of 2025.

• **Invested in New Technologies to Support Sustained Growth –** With a focus on sustained long-term growth, we invested over $5 million in the development of new product offerings and the expansion of existing technologies to markets outside the traditional energy industry. Our continued commitment to innovation and sustainable growth led to:

&nbsp;&nbsp;&nbsp;&nbsp;◦ additional orders for our proprietary Managed Pressure Drilling and Riser Gas Handling System;

&nbsp;&nbsp;&nbsp;&nbsp;◦ an initial order for our patented Low Impact Workover Package; and

&nbsp;&nbsp;&nbsp;&nbsp;◦ the receipt of a Spotlight on New Technology<sup>®</sup> Award from the Offshore Technology Conference for our TowerLok<sup>™</sup> Wind Tower Connector Technology.

• **Returned Capital to Stockholders –** Purchased $17 million of our common stock (or 5% of our shares outstanding as of January 1, 2025) in 2025.

• **Improved Liquidity Position –** Generated cash flow from operations of $105 million in 2025, invested $31 million in capital expenditures, sold idled facilities and other property and equipment for $20 million, purchased $70 million in principal amount of our 4.75% convertible senior notes and purchased $17 million of our common stock. Cash on-hand increased to $70 million during 2025 and our outstanding debt was reduced to $55 million.

**Summary of Incentive Compensation**

The following tables present the payout percentages achieved in 2025 under our Corporate performance-based incentive compensation programs, together with the relevant weightings of the various short- and long-term components. Both short-term and long-term incentive awards, including cash-based performance awards based on three-year relative TSR performance and stock-based performance awards based on three-year cumulative EBITDA paid out below target.

**2026 Executive Compensation Preview**

During 2025, the Compensation Committee, the committee's independent consultant and management reviewed the design of the short- and long-term incentive compensation programs. The purpose of the review was to evaluate program design and rigor and determine if the current metrics required adjustment to motivate long-term sustainable performance, better align executive and stockholder interests and reward for performance. No material changes were made to our short-term or long-term incentive metrics for 2026.

**Compensation Discussion and Analysis**

Throughout this CD&A, the following individuals are referred to as our Named Executive Officers and are included in the Summary Compensation Table which follows:

• Cindy B. Taylor—President & Chief Executive Officer

• Lloyd A. Hajdik—Executive Vice President, Chief Financial Officer & Treasurer

• Philip S. "Scott" Moses—Executive Vice President and Chief Operating Officer

• Brian E. Taylor—Senior Vice President, Controller and Chief Accounting Officer (no relation to the Company's Chief Executive Officer, Cindy B. Taylor)

The Compensation Committee of the Board of Directors provides overall guidance to the Company's executive compensation program and administers incentive compensation plans.

The executive compensation program includes three primary elements which are largely performance oriented and, taken together, constitute a balanced method of establishing total compensation for the Company's executive officers. The three major elements consist of a) base salary, b) annual incentive compensation, and c) long-term incentive awards.

**Executive Total Compensation Philosophy**

The Company's philosophy regarding the executive compensation program for our Named Executive Officers and other senior managers has been to design a compensation package that provides competitive base salary levels and compensation incentives that (i) attract and retain individuals of outstanding ability in these key positions, (ii) recognize the performance of the Company relative to the performance of other companies of comparable size, complexity and quality and against budget goals and (iii) support both the short-term and long-term strategic goals of the Company. The Compensation Committee believes this approach closely links the compensation of the Company's executives to the execution of the Company's strategy and the accomplishment of Company goals that coincide with stockholder objectives.

**Compensation Program Objectives**

• Attract, motivate, reward and retain key employees and executive talent required to achieve corporate strategic plans;

• Reinforce the relationship between strong individual performance of executives and business results;

• Align the interests of executives with the long-term interests of stockholders; and

• Design a compensation program that neither promotes overly conservative actions or excessive risk taking.

The compensation program is designed to reward executives for long-term strategic management and the enhancement of stockholder value.

**2025 Advisory Vote on Executive Compensation**

In 2023, a majority of stockholders expressed their preference for an advisory vote on executive compensation occurring every year, and we have implemented their recommendation.

At our 2025 Annual Meeting of Stockholders, our stockholders expressed their support for the compensation program for our Named Executive Officers. A total of 73% of the votes cast supported our executive compensation policies and practices for our Named Executive Officers at our 2025 Annual Meeting of Stockholders. In reviewing our executive compensation program for the 2025 year, our Compensation Committee considered the results of last year's advisory vote on executive compensation and feedback obtained through stockholder outreach in their overall assessment of our programs. The Compensation Committee considered stockholder feedback, peer data and other market conditions when determining the types and amounts of compensation to be paid to Named Executive Officers.

**Compensation Discussion and Analysis**

**Compensation Alignment with Stockholders**

Demand for most of our products and services depends substantially on the level of capital expenditures invested in the oil and natural gas industry, which has experienced significant variations due to volatility in underlying commodity prices, particularly that of crude oil.

Given that a substantial portion of the total compensation granted to our Named Executive Officers is at risk (82% for our Chief Executive Officer and 75% in aggregate for our other Named Executive Officers in 2025), actual paid values of compensation have also experienced significant variation over the period.

As further discussed above in the section titled "Executive Summary," our 2025 results benefited from growth in offshore and international spending. However, our overall

performance was tempered by an industry-wide decline in U.S. well completions in 2025 and increased U.S. tariffs on imported goods. Please see the section titled "Pay versus Performance" for further discussion and details.

Our Compensation Committee is very sensitive to market conditions and stockholder returns. However, the Compensation Committee also strives to balance that sensitivity with the need to retain qualified executives in a highly cyclical industry so that stockholder returns can be maximized over the longer term.

We maintain active dialogue with our stockholders throughout the year and view engagement as a key component of effective corporate governance. Members of management engaged with stockholders representing over 70% of our outstanding shares.

These discussions covered a range of topics, including corporate strategy, governance matters, executive compensation and various other assessment criteria. Feedback from these engagements was shared with the Board and considered as part of its ongoing oversight and decision-making processes.

**Compensation Comparisons Relative to Market**

The Compensation Committee establishes executive compensation based primarily on a review of the executive's performance and compensation history while taking into account corporate performance and stockholder returns. In the exercise of its duties, the Compensation Committee periodically evaluates the Company's executive compensation against that of comparable companies. The Compensation Committee considers the market to consist primarily of the oilfield services industry. Compensation data is periodically obtained for a selected peer group approved by the Compensation Committee consisting of energy services companies of comparable size and business complexity.

In selecting comparison companies, the Compensation Committee considered various factors including each company's participation in the energy services sector as well as size metrics, including annual revenues, assets, enterprise value, market capitalization, business complexity, profitability, returns on equity and assets, the number of divisions/segments, countries in which they operate and total number of employees. The selected peer companies change from time to time to ensure their continued appropriateness for benchmarking purposes.

In evaluating the peer group and other comparison data for compensation purposes, the Compensation Committee neither bases its decisions on quantitative relative weights of various factors, nor follows mathematical formulas. Rather, the Compensation Committee exercises judgment

after considering the factors it deems relevant. The Compensation Committee has engaged Meridian Compensation Partners (the "Consultant") to, among other things, assess the reasonableness of the peer group of companies used for comparison purposes (more about the Compensation Committee's relationship with the Consultant is discussed below).

At the request of the Compensation Committee in August 2024, the Consultant recommended a list of 13 publicly traded companies as the Company's peer group for assessing 2025 compensation decisions (collectively, the "Peer Group"). The Peer Group for 2025 was unchanged from 2024. In September 2025, the Compensation Committee approved certain changes to the Company's Peer Group for 2026 compensation planning purposes, including the removal of Archrock, Inc. and Oceaneering International, Inc. due to their larger size and NPK International, Inc. due to operational considerations. Additions included Cactus, Inc., Hunting PLC, SEACOR Marine Holdings Inc. and Solaris Energy Infrastructure, Inc. The Peer Group identified for purposes of both the 2025 and 2026 compensation programs is reflected below:

<sup>(1)</sup> Although Diamond Offshore Drilling, Inc. was acquired by Noble Corporation plc in September 2024, they were included for 2025 compensation planning purposes based on the fact the compensation data for benchmarking purposes is derived from 2024 proxy statement disclosures.

<sup>(2)</sup> Dril-Quip, Inc. was renamed Innovex International, Inc. following the merger with Innovex Downhole Solutions, Inc. in September 2024.

<sup>(3)</sup> Newpark Resources, Inc. changed the company name to NPK International, Inc. in December 2024.

**Compensation Practices as They Relate to Risk Management**

Our compensation policies and practices are designed to provide rewards for short-term and long-term performance, both on an individual basis and at the entity level. In general, optimal financial and operational performance, particularly in a competitive business, requires some degree of risk-taking. Our compensation strategies are designed to encourage Company growth and appropriate risk taking but not to encourage excessive risk taking. We also attempt to design the compensation program for our larger general employee population so that it does not inappropriately incentivize our employees to take unnecessary risks in their day-to-day activities.

Our compensation arrangements contain certain design elements that are intended to minimize the incentive for taking unwarranted risks to achieve short-term, unsustainable results. Those elements include a maximum amount that can be earned under the annual incentive cash compensation and performance award programs.

In combination with our risk management practices, we do not believe that risks arising from our compensation policies and practices for our employees, including our Named Executive Officers, are reasonably likely to have a material adverse effect on us.

**Compensation Discussion and Analysis**

**Elements of Compensation**

In order to further its pay-for-performance goal, the Compensation Committee has determined that it is appropriate to deliver a significant portion of executive compensation that is "at risk" and tied to corporate performance. The following charts depict elements of the target compensation for the Chief Executive Officer and, collectively, for the other Named Executive Officers of the Company during 2025. Approximately 82% of the compensation granted to our Chief Executive Officer and 75% granted to our other Named Executive Officers was at risk, demonstrating management's alignment with stockholder objectives.

When designing incentives, the Compensation Committee employs selected performance metrics to ensure a strong link between executive compensation and performance. Metrics such as Adjusted EBITDA, cash flow from operations, free cash flow, average liquidity levels and relative stock price performance have been used in the past to align executive compensation to Company performance.

In terms of 2025 grant date fair value awarded under our long-term incentive program, 25% was awarded in the form of cliff-vesting stock-based performance awards, 25% was awarded in the form of cliff-vesting cash-based performance awards and 50% was awarded in the form of time-based restricted stock awards to our Chief Executive Officer and our other Named Executive Officers (see page [52](#ia8b1ed578b074cfc81fcbf6bb9b970dc_100)), with the exception of Mr. B. Taylor, who was awarded 100% in the form of a time-based restricted stock award. Ms. C. Taylor provides the Compensation Committee with input regarding the performance of other Company executives and makes compensation recommendations with respect to these individuals. In light of market data and analysis and other factors noted above, the Compensation Committee makes an independent judgment with respect to compensation levels for each of the other Named Executive Officers. Ms. C. Taylor does not provide input or participate in the review or determination of her own compensation. An explanation of the individual pay elements of our executive officer compensation program and the impact of performance on each element is summarized below.

**Compensation Discussion and Analysis**

**Reported versus Actual Paid Values of Executive Compensation**

The Compensation Committee is committed to targeting reasonable and competitive compensation for the Named Executive Officers. Because a significant portion of the Named Executive Officers' compensation is at risk, the target values established at the date of award may vary substantially from the values actually paid from year-to-year.

"Reported compensation" is the total compensation that is reported in the Summary Compensation Table of our Proxy Statement which reflects equity awards at grant date values. As further described and detailed under Pay versus Performance beginning on page [61](#ia8b1ed578b074cfc81fcbf6bb9b970dc_115), "actual compensation paid" values presented in the tables below were

determined in accordance with the requirements of Item 402(v) of Regulation S-K, which requires the Company to make certain adjustments to equity compensation amounts reported in the Summary Compensation Table (including unrealized gains (losses) during the year on unvested equity awards) in an effort to more closely reflect amounts actually earned by the Named Executive Officers.

The following tables summarize "reported compensation" values for our Chief Executive Officer and collective average for the other Named Executive Officers, as compared to "actual compensation paid" values for the years ended December 31, 2021, 2022, 2023, 2024 and 2025 (in thousands):

As discussed above, "compensation actually paid" includes SEC required adjustments for unrealized gains and losses on unvested equity awards during the year.

**Base Salary**

Base salary is the stationary element of an executive's direct compensation and is intended to provide a foundation for a competitive overall compensation opportunity for the executive. The Compensation Committee reviews each executive's base salary annually. Executive officer base salaries are determined after an evaluation that considers the executive's prior experience and breadth of knowledge in the context of compensationdata from peer group companies and other similarly sized companies, the Company's and the executive's performance, and any significant changes in the executive's responsibilities. Base salaries have not increased for our Named Executive Officers since 2023 (2022 in the case of our CEO).

**Compensation Discussion and Analysis**

**Short-term Incentives**

The Company's Annual Incentive Compensation Plan ("AICP") is performance-based and provides executives with direct financial incentives in the form of annual cash bonuses based on the Company's performance. Annual incentive awards are linked to the achievement of pre-determined quantitative performance goals. The purpose of the AICP is to:

• provide focus on the attainment of annual goals that lead to long-term success of the Company;

• motivate achievement of critical annual financial performance metrics; and

• motivate employees to continually improve Company-wide and business unit performance.

The AICP is based upon metrics set by the Compensation Committee with input from management that it believes are consistent with creating stockholder value. The goals and objectives have been 100% weighted in recent years toward financial objectives for executive officers and goals that management and the Board of Directors believe will drive Company performance and protect its financial health and liquidity.Under the AICP, an incentive target percentage is established for each executive officer based upon, among other factors, the Compensation Committee's review of publicly available competitive compensation data for that position, level of responsibility, past performance and ability to impact the Company's success. Achieving results which exceed a minimum, or threshold, level of performance triggers an AICP payout. Performance at or below the threshold results in no AICP award. Target performance is earned when an executive achieves 100% of their AICP performance objective(s). Overachievement is the performance level at which short-term incentive compensation is maximized. If the performance results fall between the threshold level and the target level, 35-100% of the AICP target amount will be paid out proportionately to the distance such performance results fall between the two levels. If the performance results fall between the target level and the overachievement level, 100-200% of the AICP target amount will be paid out proportionately to the distance such performance results fall between the two levels. The 2025 award opportunities, expressed as a percentage of eligible AICP earnings (i.e. annual base salary), for our Chief Executive Officer and other Named Executive Officers are outlined below:

---

| | | | |
|:---|:---|:---|:---|
| | **2025 AWARD OPPORTUNITIES** | **2025 AWARD OPPORTUNITIES** | **2025 AWARD OPPORTUNITIES** |
| | **THRESHOLD** | **TARGET**<sup>(1)</sup> | **OVERACHIEVEMENT** |
| **Cindy B. Taylor** | 40.25% | 115% | 230% |
| **Lloyd A. Hajdik** | 31.5% | 90% | 180% |
| **Philip S. Moses** | 31.5% | 90% | 180% |
| **Brian E. Taylor** | 17.5% | 50% | 100% |

---

<sup>(1)</sup> Target percentages were held constant during 2025.

As shown in the table above, the maximum AICP overachievement percentage (payout) is limited to twice the target level percentage which helps mitigate the potential for excessive risk taking. In addition, targets and goals are adjusted upward to incorporate material acquisitions (if any) which also limits excessive risk taking. The Compensation Committee is responsible for approving the AICP performance objectives based on recommendations made by the Chief Executive Officer. The Compensation Committee sets performance goals that are measurable and quantifiable. Performance measures are selected and weighted annually to give emphasis to performance criteria that drive Company performance.

The Compensation Committee has established "earnings before interest, taxes, depreciation and amortization expense" ("EBITDA") as a primary corporate financial performance objective for each executive officer in recent years. The selection of this metric is designed to reflect current market conditions in the energy industry, particularly activity levels and oil and gas commodity prices in our areas of operation. This metric is most commonly used to measure financial performance by industry analysts and our stockholders. The short-term objectives are generally set based on the Company's annual operating plan approved by the Board of Directors.

For 2025, all Named Executive Officershad 75% of their objective based on consolidated EBITDA and 25% of their objective based upon consolidated cash flow from operations ("CFFO"). The 2025 EBITDA target was 15% above 2024 actual results and the 2025 CFFO target was increased 42% above 2024 actual results, thereby creating stretch goals for management.

At the end of each year, the Compensation Committee reviews the performance results of the Company and the level of achievement of the AICP performance objectives. The following tables present the Company's 2025 AICP results for each of our Named Executive Officers, together with relevant weightings of the various components and payouts achieved.

**Compensation Discussion and Analysis**

**Long-term Incentives**

Equity-Based Incentives—The Company makes certain stock-based awards under its Second Amended and Restated Equity Participation Plan (the "Equity Participation Plan") to better align the interests of executive officers with those of stockholders and to provide retention incentives. Specifically, the plan's purposes are to:

• place a significant percentage of executive compensation at risk;

• enable the Company to obtain and retain the services of executives considered essential to its long-term success by offering them an opportunity to own stock in the Company; and

• provide an additional incentive for executives to further the growth, development and financial success of the Company by personally benefiting through ownership of Company stock and/or rights.

The Equity Participation Plan provides for the grant of any combination of:

• restricted stock awards;

• performance awards;

• deferred stock units;

• stock options;

• stock payments or phantom stock awards; and

• dividend equivalents.

The Equity Participation Plan provides for minimum vesting periods of one year for performance awards and three years for tenure-based awards, except for a small percentage of the authorized shares available for awards under the Equity Participation Plan. Vesting may occur earlier than the minimum vesting periods with respect to no more than 5% of shares cumulatively authorized under the Equity Participation Plan. Time-based restricted stock awards generally vest in equal installments over a three-year period.

In determining appropriate awards, the Compensation Committee annually reviews each executive's past performance and experience, his or her position and ability to contribute to the future success and growth of the Company, time in the current job, base compensation and competitive market data.

The Compensation Committee also takes into account the risk of losing the executive to other employment opportunities and the value and potential for appreciation in the Company's stock. The Compensation Committee also takes into consideration that the Company has no defined benefit retirement plan nor any supplemental executive retirement benefits or similar arrangements. The Compensation Committee believes that the combination of time-based restricted stock awards and cliff-vesting performance awards, along with significant vesting requirements, are an effective method of reinforcing the long-term nature of the Company's business, in creating retention incentives and in reinforcing alignment with stockholder interests.

Higher-level positions will generally have a greater percentage of their total compensation at risk and based on longer-term incentives which are performance-based. The size of long-term incentive grants may vary and reflect a variety of factors including, among others, competitive market practices, retention priorities, total previous grants, current stock valuation and the estimated impact on future earnings. The Compensation Committee determines the award level for Named Executive Officers, if any, on an annual basis (usually at its February meeting).

In 2025, each of the Named Executive Officers received a combination of grants weighted in terms of grant date value, 50% to time-vesting restricted stock awards and 50% to cliff-vesting performance awards, except for Mr. B. Taylor, who was awarded 100% in the form of a time-vesting restricted stock award. We believe the inclusion of performance awards adds incentive for continued performance and enhances the Company's ability to attract and retain talented executives in an increasingly competitive marketplace. The Compensation Committee weighs the cost to stockholders of these grants against their potential benefit as an incentive, retention and compensation tool. In 2025, the Compensation Committee reduced the long-term incentive award value for our Chief Executive Officer from $3.6 million to $3.2 million, reflecting an approximate 11% reduction, due to downward movement in peer group total compensation.

Stock Awards. Restricted stock awards were made to the Named Executive Officers on February 20, 2025. These awards vest in three equal installments on each annual anniversary of the grant date, provided the Named Executive Officer remains an employee continuously from the date of grant through the applicable vesting date.

There is no program, plan or practice to time the award of restricted stock to Named Executive Officers in coordination with the release of material non-public information. Except in special circumstances, equity grants are made to employees annually at the time of the Board of Directors' February meeting.

Performance Awards. The performance awards represent the right to receive shares of the Company's common stock or cash in the future, subject to forfeiture conditions and achieving the identified performance objectives. The stock-based performance awards do not entitle their recipient to the right to vote, receive dividends or to any other privileges or rights of a stockholder of the Company until such time as shares of Company common stock are delivered to the recipient following vesting. Vesting of performance awards is contingent upon the Named Executive Officer's continued employment with us through the specified vesting date and our achievement of predefined performance metrics generally covering a

three-year measurement period. Depending on the level of performance achieved, our Named Executive Officers may earn between 0% and 200% of the targeted value covered

**Compensation Discussion and Analysis**

by the award. Upon the occurrence of certain events, such as a change in control or specified employment termination scenarios, vesting of the performance awards may be accelerated.

The Company utilizes a combination of relative and absolute metrics in the composition of the long-term incentive award targets.

The 2025 performance awards included: a stock-based performance award based on the achievement of a predefined cumulative EBITDA target (an absolute growth measure), and a cash-based performance award based on Relative Total Stockholder Return ("Relative TSR") compared to our Peer Group.

Cumulative EBITDA refers to the sum of EBITDA amounts for each of the three calendar years in the performance

period. This performance metric is an absolute rather than a relative performance measure. This metric is most commonly used to measure financial performance by industry analysts and our stockholders. Relative TSR performance awards granted by the Compensation Committee were cash-based to more closely correlate the level of benefit granted to recipients to amounts expensed in our financial statements. Potential payouts related to cash-based performance awards based on Relative TSR are capped at target if Relative TSR is negative over the performance period.

The tables below summarize the results achieved over the three-year performance period. Performance matrices provide for graduated award levels when achievement falls between the minimum and maximum levels.

**Compensation Discussion and Analysis**

**Benefits**

Employee benefits are designed to be broad based, competitive and to attract and retain employees. From time to time the Compensation Committee reviews plan updates and recommends that the Company implement certain changes to existing plans or adopt new benefit plans.

**Health and Welfare Benefits**

The Company offers a standard range of health and welfare benefits to all employees including executives. Named Executive Officers make the same contributions for the same type of coverage and receive the same level of benefit as any other employee for each form of coverage/benefit.

**Retirement Plans**

The Company does not offer a defined benefit retirement plan. The Company does offer a defined contribution 401(k) retirement plan to substantially all of its U.S. employees. During 2025, the Company matching contributions under the 401(k) retirement plan were: 100% match of the first 4% employee contribution and 50% match on the next 2% employee contribution.

**Deferred Compensation Plan**

The Company maintains a nonqualified deferred compensation plan (the "Deferred Compensation Plan")

that permits eligible employees and directors to elect to defer all or a part of their cash compensation (base and/or incentives) from the Company until the termination of their status as an employee or director or in the event of a change of control. Employees, including our Named Executive Officers, that participate in the Deferred Compensation Plan do not receive any additional compensation other than the employer match (as discussed above) on compensation deferred equivalent to what would have been matched in the Company's 401(k) plan, absent certain IRS limitations. A deferral election may provide for deferring different forms or levels of compensation (base salary and/or incentive compensation) during the year. Directors who elect to participate in the Deferred Compensation Plan do not receive any matching contributions. Additional details regarding the Deferred Compensation Plan are contained within the section below titled "Nonqualified Deferred Compensation."

**Other Perquisites and Personal Benefits**

The Company does not generally offer any perquisites or other personal benefits to our Named Executive Officers with an aggregate value over $10,000. Some Named Executive Officers do have Company paid club memberships, which are used for both personal and business purposes.

**Compensation Consultant**

In 2025, the Compensation Committee engaged Meridian Compensation Partners (the "Consultant") to: (i) review the peer group of companies used for comparison purposes in the preceding year and assess the peer group's continued validity; (ii) conduct a review of the competitiveness of our total direct compensation of the Named Executive Officers, relative to data disclosed in proxy statements and other filings with the SEC by the peer group of companies and survey data; (iii) conduct a pay-for-performance analysis to assess the alignment of Chief Executive Officer pay and the Company performance and the peer group of companies identified; (iv) assess compensation for non-employee directors relative to compensation programs of a peer group of companies; (v) assist in assessment of potential excise taxes pursuant to Section 4999 of the Code, assuming a change of control occurred on December 31, 2025; and (vi) assist the Compensation Committee in the performance of its duties. The decision to engage the Consultant and the approval of its compensation and other terms of engagement were made by the Compensation Committee without reliance on any recommendation of management. The Consultant's engagement was limited to executive compensation and non-employee director projects requested by the Compensation Committee, and no other services were provided to the Company or management. The Compensation Committee considered this and other factors in its recent assessment of the independence of the Consultant and concluded that the Consultant's work for the Compensation Committee does not raise any conflict of interest. Fees paid to the Consultant in 2025 were $134,000.

**Executive Compensation Policies**

The following provides a summary of some of our executive compensation practices and policies.

• *Securities Trading Policy*—The Company prohibits directors, officers and employees from trading the Company's securities on the basis of material, non-public information or "tipping" others who may so trade on such information. In addition, the policy prohibits certain officers, directors, and related persons from trading in the Company's securities without obtaining prior approval from the Company's Chief Executive Officer, Chief Financial Officer or Corporate Secretary. Executive officers and directors are expressly prohibited from trading options or any derivative type of contract related to the Company's stock.

• *Anti-Hedging/Anti-Pledging*—Directors and officers are prohibited from (i) purchasing any financial instrument that is designed to hedge or offset any decrease in the market value of the Company's stock, including prepaid variable forward contracts, equity swaps, collars and exchange funds; (ii) engaging in short sales related to the Company's common stock; (iii) placing standing orders; (iv) holding Company stock in margin accounts; and (v) pledging Company securities as collateral for a loan. See the Corporate Governance section for a more detailed discussion of our anti-hedging policy.

• *Executive Stock Ownership and Retention Guidelines*—The Compensation Committee has adopted Executive Stock Ownership and Retention Guidelines to further align the interests of executives with the interests of stockholders and further promote the Company's commitment to sound corporate governance. The Compensation Committee may, from time to time, reevaluate and revise participants' guidelines to incorporate pay changes or other events.

• *Incentive Recoupment Policy for Named Executive Officers* — In October 2023, the Company's Board of Directors adopted an incentive-based compensation recoupment policy (the "Recoupment Policy") covering its Named Executive Officers responsive to SEC required changes in NYSE listing standards. The policy provides the Company with the ability to seek recoupment of any erroneously awarded performance-based compensation received by a Named Executive Officer on or after October 2, 2023 if the Company is required to restate its financial statements due to a material

misstatement. For periods prior to October 2, 2023, our Named Executive Officers were subject to the Company's incentive compensation clawback policy discussed below.

• *Supplemental Incentive Compensation Clawback Policy*—The Company's incentive compensation clawback policy provides the Company with the ability, in appropriate circumstances, to seek restitution of any performance-based compensation received by an employee (including Named Executive Officers) as a result of such employee's fraud or misconduct, resulting in a material misstatement contained in the Company's financial statements, which results in a restatement of these financial statements. In October 2023, we adopted a new incentive compensation clawback policy to comply with new clawback laws (described above); therefore, our original policy was amended and restated to apply more generally to our employee population that may receive incentive compensation awards. However, with respect to any officer covered by the new Recoupment Policy described above, to the extent that the Recoupment Policy and our original policy conflict or potentially cover the same event, we will apply the terms of the Recoupment Policy.

• *Practices Related to the Grant of Certain Equity Awards in Relation to the Release of Material Nonpublic Information*—We do not currently grant stock options or option-like equity awards to our employees or directors, therefore we do not currently have a formal practice or policy with respect to the grant of stock options or option-like awards. However, with respect to the grant of other equity awards to our employees in 2025, we did not grant awards in connection with the release of any material nonpublic information.

• *Repricing Stock Options*—The Company's practice is to price awards at the market price on the date of award. The Company's Equity Participation Plan prohibits any repricing of options without our stockholders' approval.

**Compensation Discussion and Analysis**

The stock ownership guidelines for the senior executives are as follows:

---

| | |
|:---|:---|
| **POSITION** | **MULTIPLE OF SALARY** |
| Chief Executive Officer | 5X |
| Executive Officers (Section 16) | 2X |

---

Stock that counts toward satisfaction of the stock ownership guidelines includes:

• Company shares owned outright (i.e. open market purchases) by the executive or his or her immediate family members residing in the same household;

• Shares owned indirectly by the executive officer (e.g., by a spouse or other immediate family member or a trust for the benefit of the executive officer or his or her family), whether held individually or jointly;

• Time-based restricted shares granted to the executive officer under the Company's long-term equity incentive plan;

• Shares represented by amounts invested in the executive officer's account under the Company's 401(k) plan; and

• Shares held on behalf of the executive officer that are deemed invested in shares under the Company's Deferred Compensation Plan.

Covered executives are required to achieve their stock ownership guideline within five years from inclusion in the program and continue to maintain and hold the level of stock ownership as long as they are executive officers of the Company. All covered executives were in compliance with the Executive Stock Ownership and Retention Guidelines as of December 31, 2025.

**Executive and Change of Control Agreements**

The Company maintains Executive Agreements with its Named Executive Officers. The Executive Agreements are not considered employment agreements and the applicable executives are employed "at will" by the Company. The individual agreements provide protection in the event of a qualified termination, which is generally defined as an (i) involuntary termination of the executive officer by the Company other than for "Cause" or (ii) either an involuntary termination other than for "Cause" or a voluntary termination by the executive for "Good Reason," in each case, during a specified period of time after a corporate "Change of Control" (as defined in each Executive Agreement) of the Company. Executives who resign voluntarily without Good Reason under either arrangement do not trigger any payments.

The Change of Control provision in the Executive Agreements is intended to encourage continued employment by the Company of its executive officers and to allow such executive to be in a position to provide assessment and advice to the Board of Directors regarding any proposed Change of Control without concern that such

Ms. C. Taylor entitles her to be made whole for any excise taxes incurred with respect to severance payments that are in excess of the limits set forth under the Internal Revenue Code. The Company discontinued the practice of providing tax gross-ups in its Executive Agreements in 2010, and accordingly, the Executive Agreements entered into with Messrs. Hajdik, Moses and B. Taylor do not contain excise tax gross up protection.

The Executive Agreements have a term of three years and are extended automatically for one additional day on a daily basis, unless notice of non-extension is given by the Board of Directors of the Company, in which case the Executive Agreement will terminate on the third anniversary of the date notice is given. See "Potential Payments Under Termination or Change of Control" in this Proxy Statement for additional disclosures regarding the Executive Agreements.

<sup>(1)</sup> The amounts in this column represent the dollar amounts for the years shown of the aggregate grant date fair value of restricted stock awards and stock-based performance awards, as applicable, granted in those years computed in accordance with FASB ASC Topic 718—Stock Compensation. Values actually earned can vary greatly from reported amounts depending upon movements in the stock price during the vesting period. Generally, the aggregate grant date fair value is the aggregate amount that the Company expects to expense in its financial statements over the award's vesting schedule (generally three years) and, for stock-based performance awards, is based upon the probable outcome of the applicable performance conditions. Pursuant to SEC rules, the amounts shown exclude the impact of estimated forfeitures related to service-based vesting conditions. These amounts reflect the Company's estimated accounting expense for these awards and options, and do not necessarily correspond to the actual value that may be recognized by our Named Executive Officers. See Note 11 to our consolidated financial statements included in our Annual Report on Form 10-K for additional detail regarding assumptions underlying the value of these awards. The stock-based performance awards can potentially achieve a maximum number of shares equal to 200% of the target level of shares, depending on the Company's performance. The target number of shares and the corresponding grant date fair value of the stock-based performance awards is reflected in this table and in the Grants of Plan-Based Awards table for 2025 below. The maximum fair value of performance-based awards granted in 2025 (rather than the probable value for accounting purposes reflected in the table above) was $1,600,002 for Ms. C. Taylor, and $625,004 for each of Mr. Hajdik and Mr. Moses. The combined target value for the restricted stock awards and the stock-based performance awards was reduced by $300,000, from $2,700,000 to $2,400,000 for Ms. C. Taylor.

<sup>(2)</sup> This column includes the 2023 cash-based performance awards based on Relative TSR, which achieved a payout of 83% of target performance. Due to SEC reporting rules, the cash-based awards granted in 2024 and 2025 will not be reported in the Summary Compensation Table until 2027 and 2028, respectively, after the performance period for those awards has ended (assuming the performance criteria is achieved). Amounts reported in the "Non-Equity Incentive Plan Compensation" column for 2025 included the following for each Named Executive Officer:

<sup>(1)</sup> The amounts shown in the column "Target" reflect the target level of bonus payable under the Company's AICP (see discussion in "Compensation Discussion and Analysis—Elements of Compensation—Short–term Incentives," included herein) which is based on an executive's base salary paid during the year multiplied by the executive's bonus percentage. The base salary used in this table is the base salary in effect as of December 31, 2025; however, actual awards are calculated based on a participant's eligible AICP earnings paid in the year. The amount shown in the "Maximum" column represents 200% of the target amount. Performance results at or below the threshold level percentage of performance targets established under the AICP will result in no payments being made under the AICP. The threshold level percentage was set at 75% of target in 2025 for our Named Executive Officers. If the performance results fall between the threshold level and the target level, 35 – 100% of the target level bonus will be paid out proportionately to the distance such performance results fall between the two levels. If the performance results fall between the target level and the maximum level, 100 – 200% of the target level bonus will be paid out proportionately to the distance such performance results fall between the two levels.

<sup>(2)</sup> The amounts shown under "Estimated Future Payouts Under Non-Equity Incentive Plan Awards" include cash-based performance awards as described as "Elements of Compensation – Long-term Incentives" included herein. Target level cash-based performance awards granted in 2025 are based on Relative TSR. If the Relative TSR performance is below the 25<sup>th</sup> percentile, 100% of the cash-based performance awards will be forfeited. If the performance is between the 25<sup>th</sup> and the 75<sup>th</sup> percentiles, 50% up to 167% of the cash-based performance awards will payout. If the performance is greater than or equal to 75<sup>th</sup> percentile, the cash-based performance awards payout is 200%. However, if the Company's Relative TSR is negative, payout as a percentage of grant value will not exceed 100%. Due to SEC reporting rules, the cash-based performance awards will not be reported in the Summary Compensation Table until the 2028 Proxy Statement after the performance period has ended (assuming the performance criteria is achieved).

<sup>(3)</sup> The amounts shown under "Estimated Future Payouts Under Equity Incentive Plan" include stock-based performance awards (reflected in shares) as described as "Elements of Compensation – Long-term Incentives" included herein. Target level performance of awards granted in 2025 is based on Cumulative EBITDA. If the Cumulative EBITDA performance is less than $205.4 million, 100% of the stock-based performance awards will be forfeited. If the performance is between $205.4 million and $273.9 million, up to 100% of the stock-based performance awards vest. If the performance is between $273.9 million and $342.4 million, the stock-based performance awards vest between 100% and 200%. If the performance is greater than or equal to $342.4 million, the stock-based performance awards vest at 200%.

<sup>(4)</sup> The amounts shown in "All Other Stock Awards" column reflect the number of restricted stock awards granted in 2025 pursuant to the Company's Equity Participation Plan. These awards carry a three-year vesting requirement to be fully earned.

<sup>(5)</sup> This column shows the full grant date fair value of restricted stock awards and stock-based performance awards computed under FASB ASC Topic 718—Stock Compensation which were granted to our Named Executive Officers during 2025. Generally, the full grant date fair value is the amount that the Company would expense in its financial statements over the award vesting schedule and, for stock-based performance awards, is based upon the probable outcome of the applicable performance conditions. The target number of shares (100% of target levels) and the corresponding grant date fair value of that level of payout is reflected in this table and in the Summary Compensation table for 2025 awards above. The maximum fair value of the stock-based performance awards granted in 2025 was $1,600,002 for Ms. C. Taylor, and $625,004 for each of Mr. Hajdik and Mr. Moses. The Compensation Committee approved a reduction in target long-term incentive award value for Ms. C. Taylor from $3,600,000 to $3,200,000, representing a decrease of approximately 11%.

While not considered employment agreements, each of our Named Executive Officers is party to an Executive Agreement. For a description of these agreements, please see "Compensation Discussion and Analysis—Executive and Change of Control Agreements." The compensation amounts described in the preceding table were determinedas described under "Compensation Discussion and Analysis—Elements of Compensation." The material terms of the awards reported in the Grants of Plan-Based Awards Table below are described in the "Compensation Discussion and Analysis—Elements of Compensation—Short–term Incentives" and "—Long-term Incentives."

**Outstanding Equity Awards at 2025 Fiscal Year End**

The following table provides information on the holdings of stock options and stock awards by our Named Executive Officers as of December 31, 2025. This table includes outstanding and exercisable option awards and unvested stock awards, including restricted stock awards and stock-based performance awards. Each equity grant is shown separately for each Named Executive Officer. The vesting schedule for each grant is provided in this table, based on the option or stock award grant date or other factors, as discussed. Accelerated vesting provisions applicable to the outstanding awards are described below under "—Potential Payments Upon Termination or Change in Control." The market value of the stock awards is based on the closing market price of the Company's common stock as of December 31, 2025, which was $6.77. In accordance with disclosure requirements, stock-based performance awards have been presented in the table below assuming that the performance period ended on December 31, 2025 and that the performance level achievement would have been at target (100%) for the 2023 awards (actual results achieved were 83%), target (100%) for the 2024 awards and entry (50%) for the 2025 awards. For additional information about these awards, see the description of equity incentive compensation in "Compensation Discussion and Analysis Elements of Compensation—Long–term Incentives," included herein.

The value realized upon vesting of these awards represents the aggregate dollar amount realized by the Named Executive Officer upon vesting computed by multiplying the number of shares of stock by the closing price of the underlying shares on the applicable vesting date, which for the stock-based performance awards is the date the Compensation Committee certifies performance with respect to such awards.

**Nonqualified Deferred Compensation**

**Deferred Compensation Plan**

The Company maintains the Deferred Compensation Plan, which is a nonqualified deferred compensation plan for U.S. citizens that permits our directors and eligible employees to elect to defer all or a part of their cash compensation (for employees, base salary and/or incentive pay) from us until the termination of their status as a director or employee or a change of control.

Employees that participate in the Deferred Compensation Plan do not receive any additional compensation other than the employer match on compensation deferred equivalent to what would have been matched in the Company's 401(k) plan, absent certain IRS limitations. A deferral election may provide for deferring different forms or levels of compensation (base salary and/or incentive compensation) during the year. Participating employees are eligible to receive from the Company a matching deferral under the Deferred Compensation Plan that is intended to compensate them for contributions they could not receive from the Company under the 401(k) plan due to the various limits imposed on 401(k) plans by U.S. federal income tax laws. Directors who elect to participate in the Deferred Compensation Plan do not receive any matching contributions.

Participants in the Deferred Compensation Plan are able to invest contributions made to the Deferred Compensation Plan in investment funds approved by a Retirement Plan

Compensation Committee, which also mirror the 401(k) plan investment funds. The Company percentage match on employee contributions vests in the same manner as in the Company's 401(k) plan. Since the investment choices under the Deferred Compensation Plan are identical to the choices available under our 401(k) Plan, no above market or preferential earnings are provided under the Deferred Compensation Plan. As such, no earnings or losses on Deferred Compensation Plan amounts are reported in the Summary Compensation table.

Generally, each participant in the Deferred Compensation Plan will receive (i) a lump sum distribution or installment payments (at the participant's election) upon termination of the participant's service with the Company and its affiliates or (ii) a lump sum distribution upon a change of control (as defined in the Equity Participation Plan). For "Key Employees," as defined in IRS regulations, distributions of deferrals made after 2004 due to the Key Employee's "separation from service" will generally be delayed at least six months.

Detailed below is a summary of activity in the Deferred Compensation Plan for each Named Executive Officer.

<sup>(1)</sup> All contribution amounts for the last fiscal year reported in this table are also included in the "Salary" and "Non-Equity Incentive Plan Compensation" amounts reported in the Summary Compensation Table for 2025.

<sup>(3)</sup> This column represents net unrealized appreciation, depreciation, dividends and distributions from mutual fund and other investments for 2025 associated with investments held in the Deferred Compensation Plan.

The Company has elected to include Company owned life insurance as a component of the Deferred Compensation Plan to partially fund the cost of the plan with life insurance proceeds if a consenting participant dies. In the event of death of a consenting participant, the Company will directly

receive the full death benefit in the amount of $1,550,000. For consenting participants who are still actively employed by the Company, the Company has agreed to pay a survivor benefit equal to 50% ($775,000) of the individual coverage amount to their designated beneficiary.

**Potential Payments Upon Termination or Change of Control**

The table below reflects the amount of compensation to each of our Named Executive Officers of the Company in the event of a qualifying termination, which is generally defined as (i) an involuntary termination of the executive officer by the Company other than for "Cause" or (ii) either an involuntary termination other than for "Cause" or a voluntary termination by the executive for "Good Reason," in each case, during a specified period of time after a corporate "Change of Control". "Cause" is generally defined in the Executive Agreements as executive's conviction of (or plea of nolo contendere to) a felony, dishonesty or a breach of trust as regards the Company or any subsidiary; executive's commission of any act of theft, fraud, embezzlement or misappropriation against the Company or any subsidiary; executive's willful and continued failure to devote substantially all of his or her business time to the Company's business affairs; or executive's unauthorized disclosure of confidential information of the Company that is materially injurious to the Company. The Executive Agreements generally define "Good Reason" to mean a material reduction in the executive's authority, duties or responsibilities; a material reduction of executive's compensation and benefits; the Company's failure to obtain a written agreement from any successor or assigns of the Company to assume and perform the executive agreement; or the Company requires executive, without executive's consent, to relocate more than 50 miles. A "Change of Control" for the Executive Agreements shall generally mean any person acquires beneficial ownership of securities of the Company representing 35% or more of the combined voting power of the Company's then outstanding securities; provided, however, that if the Company engages in a merger or consolidation in which the Company or surviving entity in such merger or consolidation becomes a subsidiary of another entity, then references to the Company's then outstanding securities

shall be deemed to refer to the outstanding securities of such parent entity; a change in the composition of the Board of Directors, as a result of which fewer than a majority of the directors are incumbent directors (as defined in the applicable Executive Agreements); consummation of a merger or consolidation of the Company with another entity, other than a transaction that would result in the Company's outstanding voting securities immediately prior to the transaction continuing to represent more than 50% of the outstanding voting securities of the resulting entity; approval of a complete liquidation of the Company; or the sale or disposition of all or substantially all of the Company's assets. See "Compensation Discussion and Analysis—Executive and Change of Control Agreements" herein for additional information. The scope and terms of compensation due to each Named Executive Officer upon voluntary terminations, early retirement, retirement, for Cause termination and in the event of disability or death of the executive are the same as other salaried employees, other than with respect to the potential death benefit for participants in the Deferred Compensation Plan described above in the "Nonqualified Deferred Compensation" section.

The amounts shown in the table, which follows, assume for each of our Named Executive Officers that such qualified termination or a Change of Control was effective as of December 31, 2025 and, therefore, include compensation earned through such date. The table includes estimate amounts because actual amounts to be paid can only be determined at the time of such executive's separation from the Company or upon a Change of Control. Due to the fact that the death benefit associated with the life insurance policies for the Deferred Compensation Plan are quantified above, that amount is not repeated in the hypothetical calculations below.

**Compensation Discussion and Analysis**

**Executive and Change of Control Agreements**

Pursuant to the Company's Named Executive Officers' Executive Agreements, if the executive is terminated by the Company (other than termination by the Company for Cause, or by reason of death or disability), or if the executive voluntarily terminates employment for Good Reason, in either case, during the 24-month period following a Change of Control, then the executive is entitled to receive (i) a lump sum severance payment of two times (or two and a half in the case of Ms. C. Taylor) the sum of the executive's base salary and the target annual bonus that may be earned by the executive pursuant to the AICP for the year of termination or the year preceding the Change of Control, whichever is the greater amount, (ii) medical and dental health benefits and disability benefits coverage until the earlier of (A) 36 months and (B) the date the executive begins receiving comparable benefits from a subsequent employer, (iii) 100% vesting of all restricted shares, restricted stock units and stock options (and such options shall remain exercisable for the remainder of their term), (iv) vesting of all contributions to our 401(k) plan and Deferred Compensation Plan to the extent not already vested and (v) outplacement services equal to a maximum of 15% of the executive's salary at the time of termination until the earliest to occur of (A) December 31 of the second calendar year following the year of termination and (B) the date the executive accepts subsequent employment. Unlike "single trigger" plans that pay out immediately upon a change of control, the executive agreements require a "double

trigger" (i.e. a change of control followed by a qualified termination) for the payment of severance.

If the executive is terminated by the Company without Cause other than during the 24-month period following a Change of Control, the Executive Agreements provide (i) for a lump sum severance payment of one times (or one and one half with respect to Ms. C. Taylor) the sum of the executive's base salary and the target annual bonus that may be earned by the executive pursuant to the AICP for the year of termination, (ii) that all restrictions on restricted shares and restricted stock units will lapse and (iii) for continued medical and dental health benefits and disability benefits coverage until the earlier of (A) 24 months and (B) the date the executive begins receiving comparable benefits from a subsequent employer. Any vested, non-qualified stock options would expire after 3 months of the date of termination if not exercised prior to their expiration.

The Executive Agreement entered into with Ms. C. Taylor during 2001 contains parachute payment excise tax gross up protection. Executive Agreements entered into with Messrs. Hajdik, Moses and Mr. B. Taylor do not contain excise tax gross up protection.

To receive benefits under the Executive Agreements, the executive officer will be required to execute a release of all claims against the Company.

**Deferred Compensation Plan**

Generally, each participant in the Deferred Compensation Plan will receive, at the participant's election, a lump sum distribution or installment payments upon a change of control or a termination of the participant's service with the Company and its affiliates. For "Key Employees," as defined in IRS regulations, distributions of deferrals made after 2004 are delayed at least six months. Any other withdrawals by the participant will be made in good faith compliance with Section 409A limitations.

**Equity and Performance Awards**

The Company's restricted stock award agreements provide that restricted stock awards will become fully vested on (i) the date a Change of Control occurs or (ii) the termination of an employee's employment due to his or her death or a disability that entitles the employee to receive benefits under a long-term disability plan of the Company.

The performance awards contain potential acceleration provisions that will depend upon the timing of the acceleration event in relation to the grant date of the award. Prior to the eighteen-month anniversary of the grant date of the award, in the event that a Change of Control occurs, or the employee becomes disabled or dies, then the performance award will vest upon the occurrence of such event at the greater of "target" levels or a "determined percentage" of target. The determined percentages with respect to the stock-based performance awards (cumulative EBITDA) would be calculated using the actual level of performance attained for the award on the last day of the fiscal quarter that is coincident with or immediately precedes the Change of Control or the

termination event, as applicable. The determined percentages with respect to the cash-based performance awards (Relative TSR) would be calculated using the actual level of performance attained for the award on the date of the applicable vesting event (the Change of Control), or the termination event, as applicable. In the event that the acceleration is due to the employee's disability or death, both the target level and the determined percentage will be further multiplied by a fraction that is based upon the number of days the employee was actually employed during the performance period compared to the total number of days in the performance period.

On or after the eighteen-month anniversary of the grant date of the performance award, in the event that a Change of Control occurs or the employee becomes disabled or dies, then the performance award will vest upon the occurrence of such event at the greater of "target" levels or the "determined percentage" of target described above. In the event that the employee retires

**Compensation Discussion and Analysis**

(defined as a termination after the age of 58 that is due to a reason other than death or disability), the performance award will vest based upon the "determined percentage" of target described above, but if the retirement date occurs prior to the eighteen-month anniversary of the grant date of the award, then the award will be further multiplied by a fraction that is based upon the number of days the employee was actually employed during the performance period compared to the total number of days in the performance period.

For performance awards, in the event we terminate the employee's employment without "Cause" (and not by reason of death or disability) prior to the end of the performance period, then the performance award will vest on the date of such termination based upon the "determined percentage" of target as described above, but, if such termination of employment occurs prior to the eighteen-month anniversary of the grant date of the award, then the award will be further multiplied by a fraction that

is based on the number of days the employee was actually employed during the performance period compared to the total number of days in the performance period. For this purpose, the term "Cause" has the same meaning as defined in the employee's individual executive agreement or, in the absence of such an agreement or definition, means conviction of (or plea of nolo contendere to) a felony, dishonesty or a breach of trust as regards the Company or any subsidiary; commission of any act of theft, fraud, embezzlement or misappropriation against the Company or any subsidiary; willful and continued failure to devote substantially all of the employee's business time to the Company's business affairs; or unauthorized disclosure of confidential information of the Company or any subsidiary.

The Company has also granted Mr. B. Taylor cash-based long-term incentive awards that would become fully vested on (i) the date a Change of Control occurs or (ii) the termination of his employment due to his death.

**Quantification of Payments**

Shown in the table below are potential payments upon the assumed (i) involuntary not for Cause termination of our Named Executive Officers other than during the 24-month period following a Change of Control, or (ii) involuntary not for Cause termination or termination by the Named Executive Officer for "Good Reason," in either case, duringthe 24-month period following a Change of Control of the Company occurring as of December 31, 2025. In addition, the tables that follow show the potential payments upon the hypothetical (i) disability, retirement or death of our Named Executive Officers, and (ii) Change of Control of the Company, in each case, occurring as of December 31, 2025.

**Compensation Discussion and Analysis**

**Pay Versus Performance**

**Compensation Actually Paid Versus Performance Table**

As required by Item 402(v) of Regulation S-K, we are providing the following information regarding the relationship between executive compensation and the Company's financial performance for each of the five years in the period ended December 31, 2025. In determining "compensation actually paid" to its Named Executive Officers pursuant to the applicable SEC rules, the Company is required to make certain adjustments to the executive compensation amounts reported in the Summary Compensation Table included in this Proxy Statement.

To determine the "actual" compensation paid to our Chief Executive Officer and the average "actual" compensation paid to our other Named Executive Officers, the adjustments described and quantified below were made related to equity compensation amounts reported in the Summary Compensation Table.

For each year presented in the following tables, the grant date fair value of equity awards reported in the Summary Compensation Table were deducted and the following adjustments were added back or subtracted, as applicable:

• the December 31 fair value of equity awards granted during the year that were unvested at the end of the year;

• the change in fair value of any awards granted in prior years that were unvested at the end of the year;

• for awards granted in prior years that vested during the year, the change in the fair value from the end of the prior year to the vesting date; and

• for awards granted in prior years that were forfeited (e.g. due to failure to meet the applicable vesting conditions), the fair value (if any) of the award at the end of the prior year was deducted.

For awards that vest based on performance conditions, the value was determined using probable valuation assumptions as of each applicable valuation date. As the Company's Named Executive Officers do not participate in any defined benefit (i.e. pension) plans, no related adjustments were required to amounts reported in the Summary Compensation Table totals.

The following table summarizes compensation values reported in the Summary Compensation Table for our Chief Executive Officer and the average for our other Named Executive Officers, as compared to "compensation actually paid" and the Company's financial performance for each of the five years in the period ended December 31, 2025:

<sup>(5)</sup> The Company uses Consolidated Adjusted EBITDA to compare and to monitor the performance of the Company and its business segments to other comparable public companies and as a benchmark for the award of incentive compensation under its annual incentive compensation plan. The term Consolidated Adjusted EBITDA consists of net income (loss) plus net interest expense, taxes, depreciation and amortization expense, impairments of assets, and facility consolidation/closure and other charges, less gains on the sale of a previously idled property and extinguishments of debt.

As shown in the tables above, changes in the market price of the Company's common stock following the date of grant can significantly impact the level of "compensation actually paid" to the Company's Named Executive Officers.

**2021 Discussion**

While customer-driven activity improved in 2021 from the low levels of 2020, the Company's reported results and stock price performance in 2021 continued to reflect the negative impact of the global response to the COVID-19 pandemic, ongoing uncertainties related to future crude oil demand and supply, market pressures driving increased capital discipline and, to a lesser extent, supply chain disruptions. During 2021, the Company continued its restructuring efforts, closed additional facilities and exited certain underperforming service offerings. Additionally, the Company completed two significant financing transactions, which served to extend the maturity profile of the Company's debt and provide greater access to liquidity. While significant accomplishments were realized in 2021, "compensation actually paid" to the Company's Chief Executive Officer and other Named Executive Officers only increased from 2020 due primarily to there being no further material declines in the Company's stock price year-over-year leading to a reduction in the amount of unrealized losses incurred. See the reconciliations above for further details regarding the impact of unrealized losses on unvested equity awards between 2020 and 2021.

**Compensation Discussion and Analysis**

**2022 Discussion**

The Company's financial results and stock price performance improved significantly in 2022 – driven by increased capital investments by our customers, together with internal cost reduction and strict capital discipline measures and other corporate actions. Similarly, "compensation actually paid" to each of the Company's Named Executive Officers increased from 2021 levels due primarily to an increase in the fair value of unvested equity awards and, to a lesser extent, short-term cash incentives earned associated with the Company exceeding annual financial performance goals established at the beginning of 2022.

**2023 Discussion**

The Company's financial results continued to improve in 2023, driven by growth in offshore and international spending, partially offset by an industry-wide decline in U.S. well completions. Despite this improvement, the Company stock price performance declined due to macro-economic conditions triggering reductions in commodity prices. While significant accomplishments were achieved in 2023, "compensation actually paid" to each of the Company's Named Executive Officers decreased from 2022 levels due to decreases in the fair value of unvested equity awards and short-term cash incentives earned, partially offset by an increase in payouts under the cash-based performance awards (payouts earned for awards related to the 2021 – 2023 performance period were at 55% of target level performance, while there were no payouts earned for the 2020 – 2022 period).

**2024 Discussion**

Our operating results for 2024 (which included significant asset impairment and restructuring charges, partially offset by a gain associated with the sale of a previously idled facility) reflect the impact of operators' continued investment in offshore and international projects and associated backlog conversion, partially offset by a decline in land-based investments by our U.S. customers, competitive market conditions and management's decision to exit certain underperforming locations and service offerings in the United States. While significant accomplishments were achieved in 2024, "compensation actually paid" to each of the Company's Named Executive Officers decreased from 2023 levels due to declines in the fair value of unvested equity awards and reductions in short-term cash incentives earned, partially offset by an increase in payouts under the cash-based performance awards (payouts earned for awards related to the 2022 – 2024 performance period were at 67% of target level performance).

**2025 Discussion**

The Company's operating results in 2025 (which included significant asset impairment and restructuring charges) reflect management's decision to exit certain underperforming service offerings in the United States as well as the effect of reduced spending by customers operating in the United States in response to lower crude oil prices, competitive market conditions and increased U.S. tariffs on imported goods. Partially offsetting these trends were stronger offshore and international project activity, supported by backlog growth. Despite weaker market conditions and higher tariffs, the Company expanded returns and grew Adjusted EBITDA by 8% to $83 million in 2025 through its restructuring efforts. "Compensation actually paid" to each of the Company's Named Executive Officers in 2025 increased from 2024 levels due to increases in: the fair value of unvested equity awards (compared to declines experienced in 2024); short-term cash incentives earned (85% of target level payout); and payouts under the cash-based performance awards (payouts earned for awards related to the 2023 – 2025 performance period were at 83% of target level performance). See "Executive Summary" beginning on page [35](#ieb25111cd021463597203e5a9d833edf_9383) for further discussion of 2025 accomplishments and priorities.

**2025 CEO Pay Ratio**

As required by Section 953(b) of the Dodd-Frank Act, and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of Ms. C. Taylor. Due to headcount reductions made as part of the ongoing restructuring efforts in 2025, we determined our employee population experienced a significant change leading us to recalculate our median employee compensation. The amounts and ratios described below have been prepared pursuant to applicable rules. Although some amounts may represent actual dollars paid to our Chief Executive Officer or that would be paid to our hypothetical median employee, other amounts are estimates based on certain assumptions or they may represent dollar amounts recognized for financial statement reporting purposes in accordance with accounting rules, but do not represent actual dollars received (e.g., dollar values of our Chief Executive Officer's stock awards). The explanations herein contain important estimates, assumptions and other information regarding our Chief Executive Officer pay ratio disclosures.

**Compensation Discussion and Analysis**

For 2025, our last completed fiscal year:

• Ms. C. Taylor had total annual compensation of $5,079,386 as reflected in the Summary Compensation Table included in this Proxy Statement.

• Our median employee's annual total compensation was $53,239.

• As a result, we estimate that Ms. C. Taylor's 2025 annual total compensation was approximately 95 times that of our median employee.

To identify the median employee, we took the following steps:

• We determined that, as of December 31, 2025, our employee population consisted of 2,172 individuals (as reported in Item 1, Business, in our 2025 Form 10-K). This population consisted of our full-time and part-time employees (including both active employees and employees on leave as of December 31, 2025).

• We selected December 31, 2025, as our identification date for determining our median employee because it enabled us to make such identification in a reasonably efficient and economic manner utilizing 2025 annual compensation amounts.

• We used a consistently applied compensation measure to identify our median employee by comparing the actual amount of salary or wages as reflected in our payroll records. Compensation was not annualized for employees that were not employed by us for all of 2025

• For all employees located outside of the United States, we obtained similar payroll records and converted such information into U.S. dollars using the year-end currency exchange rate.

To determine the annual total compensation of our median employee and our CEO in 2025, we took the following steps:

• After we identified our median employee, we combined all of the elements of such employee's compensation for the 2025 year in accordance with the requirements of Item 402(c)(2) (x) of Regulation S-K, resulting in annual total compensation of $53,239.

• With respect to the annual total compensation of our CEO, we used the amount reported in the "Total" column of our 2025 Summary Compensation Table included in this Proxy Statement.

**ITEM 3:**

**Ratification of Appointment of Independent Registered Public Accounting Firm**

The Audit Committee has appointed Deloitte & Touche LLP ("Deloitte"), an independent registered public accounting firm, to audit the consolidated financial statements of the Company for the year ending December 31, 2026, in accordance with its charter. The Audit Committee's decision to appoint Deloitte our independent auditor was based on the following considerations: knowledge of the manufacturing and services industry, global capabilities and technical expertise, auditor independence and objectively, and the potential benefit of rotating to another independent audit firm. Based on these considerations, the Audit Committee believes that the selection of Deloitte is in the best interest of the Company and its stockholders. Therefore, the Audit Committee recommends that

stockholders ratify the appointment of Deloitte. Ratification will require the affirmative vote of a majority of the voting power of the shares present or represented by proxy at the Annual Meeting and entitled to be voted on the matter. Although ratification of Deloitte as the Company's independent registered public accounting firm for the year ending December 31, 2026 is not required by our bylaws or otherwise, our Board of Directors is submitting the selection of Deloitte to our stockholders for ratification as a matter of good corporate practice. Although this vote is not binding on the Board or the Audit Committee, if the selection of Deloitte is not ratified, the Audit Committee may reconsider its decision.

**Change in Independent Registered Accounting Firm**

On February 27, 2025, the Audit Committee dismissed Ernst & Young LLP ("EY") as the Company's independent registered public accounting firm.

During the Company's fiscal year ended December 31, 2024 during the subsequent interim period from January 1, 2025 through February 27, 2025, (i) there were no disagreements with EY on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures that, if not resolved to EY's satisfaction, would have caused EY to make reference to the subject matter of the disagreement in connection with its reports and (ii) there were no "reportable events" as defined in Item 304(a)(1)(v) of Regulation S-K.

We previously provided EY with a copy of the above disclosures as included in our Current Report on Form 8-K filed with the SEC on March 4, 2025, and requested EY to furnish us with a letter addressed to the SEC stating whether EY agreed with the statements made by us in response to Item 304(a) of Regulation S-K and, if not, stating the respects in which it does not agree. A copy of EY's letter, dated March 4, 2025, is attached as Exhibit 16.1 to that Current Report on Form 8-K, and is incorporated herein by reference.

The audit reports of EY on the consolidated financial statements of the Company for the fiscal year ended December 31, 2024 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

On February 27, 2025, the Audit Committee approved the engagement of Deloitte as its new independent registered public accounting firm. Deloitte's appointment will be for the Company's fiscal year ending December 31, 2025.

During the Company's fiscal year ended December 31, 2024, and for the subsequent interim period through February 27, 2025, neither the Company nor anyone on its behalf consulted Deloitte regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the consolidated financial statements of the Company, in connection with which neither a written report nor oral advice was provided to the Company that Deloitte concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a disagreement as defined in Item 304(a)(1)(iv) of Regulation S-K or a reportable event as described in Item 304(a)(1)(v) of Regulation S-K.

Each share of common stock outstanding on the record date is entitled to one vote. Stockholders may not cumulate their votes. There are no matters that require a supermajority vote under our certificate of incorporation. Our bylaws permit amendment by a majority vote of stockholders.

The record date for the stockholders entitled to notice of and to vote at the Annual Meeting was the close of business on March 18, 2026. At the record date, 60,199,807 shares of common stock were outstanding and entitled to be voted at the Annual Meeting.

The presence, in person or by proxy, of the holders of a majority of the voting power of all outstanding shares of the Company entitled to vote generally in the election of directors as of the record date is necessary to constitute a quorum at the Annual Meeting. If a quorum is not present, the chair of the meeting or the majority of the shares so represented at the Annual Meeting have the power to adjourn the Annual Meeting from time to time, without notice other than as required by law or our bylaws. At any adjourned Annual Meeting of Stockholders at which a quorum is present, any business may be transacted that might have been transacted at the Annual Meeting of Stockholders as originally notified.

Directors will be elected by a plurality of the votes of the shares present in person or represented by proxy cast at the Annual Meeting and entitled to vote on the election of directors. A ballot for a nominee that is marked "withheld" will not be counted as vote cast. However, in accordance with the Company's Corporate Governance Guidelines, which were last amended on May 13, 2025, any director who receives a greater number of votes "withheld" form his or her election than votes "for" in an uncontested election is required to promptly tender his or her resignation for consideration by the Nominating, Governance and Sustainability Committee following certification of the stockholders vote. The Nominating, Governance and Sustainability Committee shall promptly consider the resignation offer and make a recommendation to the Board of Directors as to whether the resignation should be accepted. The Board of Directors will render its decision on the tendered resignation with the affected director abstaining. Approval of the advisory vote on executive compensation and ratification of the selection of the Company's independent registered public accounting firm each requires the affirmative vote of a 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 matter. An automated system that the Company's transfer agent administers will tabulate the votes. Brokers who hold shares in street name for customers are required to vote shares in accordance with instructions received from the beneficial owners.

Under the applicable rules of the NYSE, brokers are permitted to vote on discretionary items if they have not received instructions from the beneficial owners, but they are not permitted to vote (a "broker non-vote") on non-discretionary items absent instructions from the beneficial owner. If you hold your shares in street name and you do not give voting instructions to your broker, pursuant to NYSE Rule 452, your broker will not be permitted to vote your shares with respect to "Item 1: Election of Directors" and "Item 2: Advisory Vote on Executive Compensation" and your shares will be considered "broker non-votes" with respect to these proposals. If you are a street name stockholder, and you do not give voting instructions, your broker will nevertheless be entitled to vote your shares with respect to "Item 3: Ratification of Appointment of Independent Registered Public Accounting Firm" in the discretion of the broker. Abstentions occur when stockholders are present at the Annual Meeting but fail to vote or voluntarily withhold their vote for any of the matters upon which the stockholders are voting. Abstentions and broker non-votes will count in determining whether a quorum is present at the Annual Meeting. Broker non-votes will not have any effect on the outcome of voting on director elections. For purposes of voting on the ratification of the selection of the Company's independent registered public accounting firm, abstentions will have the same effect as a vote against the proposal. For purposes of the advisory vote on executive compensation broker non-votes are not counted as votes with respect to the proposal and therefore will not affect the outcome of the vote on the proposal, and abstentions are treated as a vote cast and will have the same effect as a vote against the proposal.

A proxy in the accompanying form that is properly signed and returned will be voted at the Annual Meeting in accordance with the instructions on the proxy. Any properly executed proxy on which no contrary instructions have been indicated about a proposal will be voted as follows with respect to the proposal: FOR the election of the persons named in this Proxy Statement as the Board of Directors' nominees for election to the Board of Directors; FOR the approval of the advisory vote on executive compensation; FOR the ratification of the selection of Deloitte & Touche LLP as the Company's independent registered public accounting firm; and in accordance with the discretion of the holders of the proxy with respect to any other business that properly comes before the stockholders at the Annual Meeting. The Board of Directors knows of no matters, other than those previously stated, to be presented for consideration at the Annual Meeting. The persons named in the accompanying Proxy Statement may also, in their discretion, vote the proxy to adjourn the Annual Meeting from time to time.

**Information About the Meeting and Voting**

**Stockholders Sharing the Same Address**

The Company is sending only one copy of its Proxy Statement to stockholders who share the same address, unless they have notified the Company that they want to continue receiving multiple copies. This practice, known as "householding," is designed to reduce duplicate mailings and save significant printing and postage costs as well as natural resources. If you received householded mailing this year and you would like to have additional copies of the

Company's Proxy Statement mailed to you, or you would like to opt out of this practice for future mailings, please submit your request to the Secretary of the Company either orally to (713) 470-4863 or in writing to Three Allen Center, 333 Clay Street, Suite 4620, Houston, Texas 77002. You may also contact the Company if you received multiple copies of the Annual Meeting materials and would prefer to receive a single copy in the future.

**Stockholder Proposals and Director Nominations**

Stockholders interested in submitting a proposal for inclusion in our proxy materials and for presentation at the 2027 Annual Meeting of Stockholders must follow the procedures set forth in Rule 14a-8 under the Exchange Act, and any such proposal must be received by our Secretary no later than the close of business on December 1, 2026.

As more specifically provided for in our bylaws, in order for a nomination of persons for election to our Board of Directors or a proposal of business (other than pursuant to Rule 14a-8) to be properly brought before our Annual Meeting of Stockholders, it must be either specified in our notice of the meeting or otherwise brought before the meeting by or at the direction of our Board of Directors or by a stockholder of record at the time the notice was provided, who is entitled to vote at the meeting and who complies with the notice procedures set forth in our bylaws. A stockholder making a nomination for election to our Board of Directors or a proposal of business (other than pursuant to Rule 14a-8) for the 2027 Annual Meeting of Stockholders must deliver proper notice to our Secretary at least 120 days prior to the first anniversary date of the 2026 Annual Meeting of Stockholders. In other words, for a stockholder nomination for election to our Board or a proposal of business (other than pursuant to Rule 14a-8) to be considered at the 2027 Annual Meeting of Stockholders, it should be properly delivered to our Secretary no later than January 12, 2027 (provided, however, that in the event that the date of the 2027 Annual Meeting of Stockholders is more than 30 calendar days before or more than 30 calendar days after May 12, 2027, notice by the stockholder to be timely must be so delivered not later than the close of business on the later of (A) the 120<sup>th</sup> calendar day prior to the 2027 Annual Meeting of Stockholders or (B) the 10<sup>th</sup> calendar day following the calendar day on which public announcement of the date of the meeting is first made by us).

In addition to satisfying the requirements of our bylaws, a stockholder who intends to solicit proxies in support of any director nominees other than the Company's nominees must provide written notice that sets forth the information

required by Rule 14a-19 under the Exchange Act at the time such stockholder complies with the earlier deadlines under the notice procedures of our bylaws. Thus, if a stockholder intends to solicit support of any director nominees submitted under the advance notice provisions of our bylaws for the 2027 Annual Meeting of Stockholders, then such stockholder must also provide proper written notice that sets forth all the information required by Rule 14a-19 to our Secretary at our principal executive offices no later than January 12, 2027. However, if the date of the 2027 Annual Meeting of Stockholders is more than 30 days before or after May 12, 2027, then such written notice must be delivered not later than the close of business on the later of (A) the 120th calendar day prior to the 2027 Annual Meeting of Stockholders or (B) the 10th calendar day following the calendar day on which public announcement of the date of the meeting is first made by us, unless Rule 14a-19 provides for an earlier date, in which case, such earlier date shall apply.

<sup>(1)</sup> Adjusted operating income consists of operating loss plus impairments of assets and facility consolidation/closure and other charges, less a gain on the sale of an idle property. Adjusted operating income, excluding charges and credits is not a measure of financial performance under GAAP and should not be considered in isolation from or as a substitute for operating income (loss) as prepared in accordance with GAAP. The Company has included adjusted operating income, excluding charges and credits as a supplemental disclosure because its management believes that adjusted operating income, excluding charges and credits provides investors a helpful measure for comparing its operating performance with previous and subsequent periods.

<sup>(2)</sup> The term Adjusted EBITDA consists of net loss plus net interest expense, taxes, depreciation and amortization expense, impairments of assets, and facility consolidation/closure and other charges, less gains on sale of previously idled property and extinguishment of convertible senior notes. Adjusted EBITDA is not a measure of financial performance under generally accepted accounting principles ("GAAP") and should not be considered in isolation from or as a substitute for net loss or cash flow measures prepared in accordance with GAAP or as a measure of profitability or liquidity. Additionally, Adjusted EBITDA may not be comparable to other similarly titled measures of other companies. The Company has included Adjusted EBITDA as a supplemental disclosure because its management believes that Adjusted EBITDA provides useful information regarding its ability to service debt and to fund capital expenditures and provides investors a helpful measure for comparing its operating performance with the performance of other companies that have different financing and capital structures or tax rates. The Company uses Adjusted EBITDA to compare and to monitor the performance of the Company and its business segments to other comparable public companies and as a benchmark for the award of incentive compensation under its annual incentive compensation plan. The table above sets forth reconciliations of Adjusted EBITDA to net loss, which is the most directly comparable measure of financial performance calculated under GAAP.

<sup>(3)</sup> The term free cash flow consists of net cash flows provided by operating activities less capital expenditures plus proceeds from the disposition of property and equipment and assets held for sale. Free cash flow is not a measure of financial performance under GAAP and should not be considered in isolation from or as a substitute for cash flow measures prepared in accordance with GAAP. The table above sets forth reconciliations of free cash flow to net cash flows provided by operating activities, which is the most directly comparable measure of financial performance calculated under GAAP.
