ANNUAL MEETING OF STOCKHOLDERS

To Be Held June 4, 2026


General Information About the Annual Meeting and Voting

The Board of Directors (the “Board” or “Board of Directors”) of Patterson-UTI Energy, Inc., a Delaware corporation (“Patterson-UTI” or the “Company”), is expected to make this proxy statement and its 2025 annual report available to you on the Internet or, upon your request to deliver printed versions of these materials to you by mail beginning on or about April 13, 2026. Patterson-UTI is furnishing this proxy statement in connection with the solicitation by the Board of Directors of proxies to be voted at the 2026 annual meeting of stockholders of Patterson-UTI (the “Meeting”). The Meeting will be held Thursday, June 4, 2026, at 10:00 a.m., Central Time, at our corporate headquarters, located at 10713 W. Sam Houston Parkway North, Suite 125, Houston, Texas 77064, or at any adjournment or postponement thereof.

The Notice of Internet Availability of Proxy Materials (the “Notice”) is expected to be mailed to each of Patterson-UTI’s stockholders (other than those who previously requested electronic delivery) entitled to vote at the Meeting on or about April 13, 2026.

Pursuant to the “notice and access” rules adopted by the Securities and Exchange Commission (the “SEC”), Patterson-UTI has elected to provide stockholders access to its proxy materials on the Internet. Accordingly, Patterson-UTI sent a Notice to all of its stockholders as of the record date. The Notice includes instructions on how to access Patterson-UTI’s proxy materials on the Internet and how to request a printed copy of these materials. In addition, by following the instructions in the Notice, stockholders may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis.

Choosing to receive your future proxy materials by email will save us the cost of printing and mailing documents to you and will support our sustainability efforts. If you choose to receive future proxy materials by email, you will receive an email next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials by email will remain in effect until you terminate such election.

If your shares are registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, you are considered the “stockholder of record” with respect to those shares, and the Notice was sent directly to you.

If your shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the beneficial owner of shares held in “street name,” and the Notice was forwarded to you by that organization. As a beneficial owner, you have the right to direct that organization on how to vote the shares held in your account.

Whether you are a “stockholder of record” or hold your shares in “street name,” you may direct your vote without attending the Meeting in person.

If you are a stockholder of record, you may vote by using the Internet or telephone by following the instructions in the Notice. If you request printed copies of the proxy materials by mail, you may also vote by completing, dating, signing and returning your proxy card by mail. You should sign your name exactly as it appears on the proxy card. If you are signing in a representative capacity (for example, as guardian, executor, trustee, custodian, attorney or officer of a corporation), you should indicate your name and title or capacity.

If you are the beneficial owner of shares held in street name, you may be eligible to vote your shares electronically using the Internet or telephone by following the instructions in the Notice. If you request printed copies of the proxy materials by mail, you may also vote by signing the voter instruction card provided by your brokerage firm, bank, broker-dealer, or other similar organization and returning it by mail. If you provide specific voting instructions by mail, telephone or the Internet, your shares will be voted by your brokerage firm, bank, broker-dealer, or similar organization as you have directed.

Properly submitted proxies received either by mail, Internet, telephone or in person in time to be counted for the Meeting will be voted as you have directed in your proxy, unless you revoke your proxy in the manner provided below. As to any matter for which you give no direction in your proxy, your shares will be voted as follows:

•“FOR ALL” the election of the nominees to the Board of Directors named in this proxy statement;

•“FOR” the ratification of PricewaterhouseCoopers LLP as the independent registered public accounting firm of Patterson-UTI for the fiscal year ending December 31, 2026;

•“FOR” the approval of the amendment to Patterson-UTI’s 2021 Long-Term Incentive Plan;

•“FOR” the approval, on an advisory basis, of Patterson-UTI’s compensation of its named executive officers; and

•“FOR” or “AGAINST” any other proposals that may be properly submitted at the Meeting at the discretion of the persons named in the proxy.

If you are a stockholder of record, you may revoke your proxy before the proxy is voted by either:

•submitting a new proxy with a later date, including a proxy submitted using the Internet or telephone, in time to be counted for the Meeting;

•notifying the Secretary of Patterson-UTI in writing before the Meeting that you have revoked your proxy; or

•attending the Meeting and voting in person.

If your shares are held in street name, you must obtain a proxy executed in your favor from the stockholder of record (that is, your brokerage firm, bank, broker-dealer or similar organization) to be able to vote at the Meeting (see below).

The Board of Directors is making this solicitation. We have retained Georgeson LLC, 480 Washington Blvd., 26th Floor, Jersey City, New Jersey 07310, for a fee of approximately $10,000 and the reimbursement of out of pocket costs and expenses, to assist in the solicitation of proxies on behalf of the Board. Patterson-UTI’s officers and other employees, without compensation other than regular compensation, may also solicit proxies on behalf of the Board by mail, email, the Internet, telephone, electronic means and personal interview. Patterson-UTI will pay all costs associated with this solicitation.


Shares Outstanding and Voting Rights

Only stockholders of record of Patterson-UTI’s common stock, $0.01 par value per share (the “Common Stock”), at the close of business on April 10, 2026 are entitled to notice of and to vote at the Meeting or any adjournment or postponement thereof. At the close of business on April 10, 2026, there were 379,615,632 shares of Common Stock issued and outstanding. Holders of record of Common Stock on April 10, 2026 will be entitled to one vote per share on all matters to properly come before the Meeting. A list of stockholders entitled to notice of and to vote at the Meeting will be made available during regular business hours at the offices of Patterson-UTI Energy, Inc., 10713 West Sam Houston Parkway North, Suite 800, Houston, Texas 77064 for the ten day period ending on the day before the Meeting for examination by any stockholder for any purpose germane to the Meeting.

A quorum is necessary to transact business at the Meeting. A majority of the shares of Common Stock outstanding on April 10, 2026 will constitute a quorum. The shares held by each stockholder who attends the Meeting in person, signs and timely returns the form of proxy, or properly votes using the Internet or telephone will be counted for purposes of determining the presence of a quorum at the Meeting.

If your shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the beneficial owner of shares held in “street name.” As a beneficial owner, you have the right to direct that organization on how to vote the shares held in your account in the manner provided in the voting instructions you received from that organization. Street name stockholders are also invited to attend the Meeting. However, because a street name stockholder is not the stockholder of record, you may not vote your shares at the Meeting unless you follow the procedures of your brokerage firm, bank, broker-dealer, or other similar organization for obtaining a legal proxy.

“Broker non-votes” and abstentions will be considered present at the Meeting for the purpose of determining a quorum. Broker non-votes occur when nominees, such as brokerage firms, banks, broker-dealers, or other similar organizations holding shares on behalf of the beneficial owners, are prohibited from exercising discretionary voting authority for beneficial owners who have not provided voting instructions. If you do not give instructions to your bank, brokerage firm or other agent, the bank, brokerage firm or other agent does not have authority to vote on the applicable proposal except on “routine matters.” For these reasons, please promptly vote in accordance with the instructions provided by your brokerage firm, bank, broker-dealer, or other similar organization.

PROPOSAL NO. 1

ELECTION OF DIRECTORS

Directors are elected to serve until the next annual meeting of stockholders and until their successors are elected and qualified. Under Delaware law and Patterson-UTI’s bylaws, the affirmative vote of a plurality of shares present in person or represented by proxy at the meeting at which a quorum is present is required for the election of directors.

The enclosed form of proxy provides a means for you to either:

•vote “For All” with respect to the election of the nominees to the Board of Directors listed below,

•withhold authority to vote for one or more of the nominees (i.e., "For All Except"), or

•withhold authority to vote for all of the nominees (i.e., "Withhold All").

The Board of Directors recommends that you vote “FOR ALL” of the nominees. Unless you give contrary instructions in your proxy, your properly submitted proxy will be voted “For All” with respect to the election of all of the nominees to the Board of Directors. If any nominee should become unable or unwilling to accept the nomination or election, the person acting under the proxy will vote for the election of such other person as the Board of Directors may recommend. The Board has no reason, however, to believe that any of the nominees will be unable or unwilling to serve if elected.

Because directors are elected by a plurality vote, shares as to which a stockholder withholds authority to vote and broker non-votes will not affect the outcome of the election.

Our corporate governance guidelines require that if a director receives in an uncontested election a greater number of “withhold” votes than votes cast “for” his or her election, the Nominating and Corporate Governance Committee of the Board of Directors will undertake a prompt evaluation of the appropriateness of the director’s continued service on the Board of Directors. In performing this evaluation, the Nominating and Corporate Governance Committee will review all factors it deems relevant, including the stated reasons why votes were withheld, the director’s length of service, his or her past contributions to Patterson-UTI and the availability of other qualified candidates. The Nominating and Corporate Governance Committee will then make its recommendation to the Board. The Board of Directors will review the Nominating and Corporate Governance Committee’s recommendation and consider such further factors and information as it deems relevant. The Board of Directors will act on the Nominating and Corporate Governance Committee’s recommendation no later than 90 days following the date of the stockholders’ meeting. If the Board of Directors determines remedial action is appropriate, the director shall promptly take whatever action is requested by the Board. If the director does not promptly take the recommended remedial action or if the Board of Directors determines that immediate resignation is in the best interests of Patterson-UTI and its stockholders, the Board of Directors may accept the director’s resignation that will have been tendered as follows. Each director will, as a condition to his or her appointment or election as a director or nomination as a director, agree in writing to comply with the terms of Patterson-UTI’s majority voting policy and provide to the Board of Directors an irrevocable resignation that will be effective upon (i) the failure to receive the required vote at the next annual meeting at which such director faces re-election and (ii) the Board of Directors’ acceptance of such resignation.

Set forth below is the name, age (as of the date of the Meeting), position and a brief description of the business experience during at least the past five years of each of the nominees to Patterson-UTI’s Board of Directors, as well as specific qualifications, attributes and skills of such member that were identified by the Nominating and Corporate Governance Committee when such member was nominated to serve on the Board of Directors.

Each current member of Patterson-UTI’s Board of Directors is a nominee for election to the Board of Directors and was last elected at the 2025 annual meeting of stockholders. There are no arrangements or understandings between any person and any of the directors pursuant to which such director was selected as a nominee for election at the Meeting. There are no family relationships among any of the directors or executive officers of Patterson-UTI.

Board Leadership Structure and Independent Chairman

The Board evaluates its leadership structure on an ongoing basis. The decision on whether to combine or separate the Chairman and Chief Executive Officer (“CEO”) role is determined on the basis of what the Board considers to be best for Patterson-UTI at any given point in time. Patterson-UTI’s current Board leadership structure separates the role of Chairman and CEO, and our Chairman is an independent director. In addition to having an independent Chairman, the Board has an independent Vice Chairman who works with the independent Chairman to provide independent oversight and leadership of the Board.

The independent directors meet periodically in executive sessions at which only independent directors are present, and the Chairman chairs those sessions. The Chairman serves as a liaison between the independent directors and any employee directors, consults with regard to Board and agenda items, and works with the chairpersons of Board committees as appropriate. The Chairman also participates from time to time in meetings with large stockholders.

The Nominating and Corporate Governance Committee and the Board currently believe that the Board’s leadership structure, which includes the separation of the role of CEO and Chairman, is appropriate because it, among other things, provides for sufficient independence between the Board and management and for an independent director who provides board member leadership.


Board Role in Risk Oversight

The Board has adopted Corporate Governance Guidelines, which can be accessed electronically in the “Governance” section of Patterson-UTI’s website at www.patenergy.com. The Guidelines describe one of the Board’s primary responsibilities as overseeing Patterson-UTI’s processes for assessing and managing risks. The Board delegates to its committees responsibility for overseeing certain types of risk, as reflected in the chart below, and the committees in turn report regularly to the Board on their respective areas of oversight.


Board of Directors •The Board oversees assessment of major risks facing the Company and, to the extent the Board deems it appropriate, evaluates options for their mitigation. The risks that the Board routinely oversees, either directly or by delegating to a committee, include those related to safety, operational, financial, strategy, technology, competition, legal, regulatory and sustainability matters, including climate change-related matters. •The Board and its committees discharge their oversight responsibility, in part, through regular inquiries from the Chairman of the Board and other directors to senior management, regular discussions during Board and committee meetings of general and specific risks to Patterson-UTI, and periodic communications with senior management regarding particular risks and events. •The Board oversees risk management by our senior management team, in part, by reviewing and evaluating major financial objectives, critical strategies, and long-term plans, including major allocations of capital, significant proposed business acquisitions and divestitures, safety and operating performance, sustainability performance, and stockholder returns.

Management's Role in Risk Management

Our senior management identifies risks and opportunities through discussions with employees and other stakeholders, including customers, investors, trade associations and industry groups; engagement with sustainability-focused groups; and our own business risk assessments, as well as regular monitoring of legal, regulatory and policy changes with the potential to affect the industry as well as our company specifically. We believe that climate risks are inherently business risks, and our assessment of these climate-related transition and physical risks is integrated into our business risk assessment process.

Our senior management and representatives from our business units regularly communicate with the Board on risk management matters. Senior management conducts regular risk assessments to identify risks that have the potential to significantly affect our business over the short-, medium- and longer term and reviews with the Board risk mitigation and oversight measures, including prioritization of risk management and allocation of responsibility within the Company for the management of a particular risk.


Meetings and Committees of the Board of Directors; Director Independence


Meetings

The Board of Directors met seven times during the year ended December 31, 2025. Each then-serving director attended, in person or by telephone, at least 75% of the aggregate of all meetings held by the Board and meetings of each committee on which such director served. Although Patterson-UTI does not have a formal policy regarding attendance by members of the Board at its annual meetings of stockholders, directors are invited to attend annual meetings of Patterson-UTI stockholders. All of our directors attended the 2025 annual meeting of stockholders either in person or by telephone.


Director Independence

A majority of the members of the Board of Directors are independent within the meaning of the Nasdaq Stock Market, Inc. (“Nasdaq”) listing standards. Specifically, the Board has determined that Messrs. Drummond, Halverson, Huff, Jaime and Stewart and Mses. Cepak, Judah, Nelson and Robertson are independent within the meaning of the Nasdaq listing standards. In addition, Leslie A. Beyer, who served on the Board until September 18, 2025, qualified as independent during her service on the Board. In making its independence determinations, the Board considered transactions occurring since the beginning of 2025 between Patterson-UTI and entities associated with the independent directors or their immediate family members. The Board considered that since October 2023, Mr. Stewart has been employed by an organization that does business in the ordinary course with a subsidiary of Patterson-UTI. The amount received by Patterson-UTI or such other organization in each of the last three fiscal years did not exceed the greater of $200,000 or 1% of either Patterson-UTI’s or such organization’s consolidated gross revenues.


Committees of the Board of Directors (1)

The Board of Directors has established four standing committees: an Executive Committee, an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. The Board of

Directors has adopted a written charter for the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee.

(1) In April 2026, the Board of Directors dissolved the Sustainability Committee for administrative convenience and re-allocated that committee's responsibilities among the remaining committees. In particular, the Audit Committee assumed former Sustainability Committee topics pertaining to health, safety and environmental protection policies, the Compensation Committee assumed former Sustainability Committee topics pertaining to human capital management policies and practices, and the Nominating and Corporate Governance Committee assumed former Sustainability Committee topics pertaining to sustainability-related issues. The Board of Directors believes these changes help streamline our board oversight structure and will allow the Board of Directors and its remaining committees to more efficiently and effectively deploy resources and focus their attention on matters that drive long-term shareholder value. The Sustainability Committee’s members during 2025 included Mses. Nelson (chair) and Judah and Messrs. Drummond, Jaime and Stewart, and, prior to her departure from the Board, Ms. Beyer. The Sustainability Committee met five times during 2025.

Consideration of Director Nominees

On behalf of the Board, the Nominating and Corporate Governance Committee considers director nominees recommended by Patterson-UTI’s stockholders if the recommendations are made in accordance with all legal requirements, including applicable provisions of Patterson-UTI’s restated certificate of incorporation and bylaws. A stockholder’s notice to the Secretary of Patterson-UTI shall contain certain information specified in Patterson-UTI’s bylaws regarding the stockholder and the proposed nominee. See “Other Matters—Stockholder Proposals for 2027 Annual Meeting” and Article I, Section 8 and Article I, Section 11 of Patterson-UTI’s bylaws.

The number of directors may be fixed or changed by amendment of Patterson-UTI's bylaws or by resolution of the Board. The Board assesses periodically, in connection with director refreshment and other considerations, whether a larger or smaller number of directors would be preferable.

The Nominating and Corporate Governance Committee determines qualification criteria and procedures for the identification and recruitment of candidates for election to serve as directors of Patterson-UTI. The Nominating and Corporate Governance Committee relies on the knowledge and relationships of Patterson-UTI and its officers and directors, as well as third parties when it deems appropriate, to identify and evaluate nominees for director, including nominees recommended by stockholders (which are evaluated in the same manner as nominees identified by other sources). In evaluating a nominee for director, the Nominating and Corporate Governance Committee considers the nominee’s skills, expertise, industry and other knowledge, personal and professional ethics, integrity and values, sound business judgment and willingness to commit sufficient time to the Board and be committed to representing the long-term interests of Patterson-UTI’s stockholders. The Nominating and Corporate Governance Committee also reviews the individual performance and qualifications of each director who wishes to be considered for nomination to the Board. Although the Nominating and Corporate Governance Committee does not have a stand-alone policy with regard to consideration of diversity in identifying director nominees, it is required, in accordance with our Corporate Governance Guidelines, to consider diversity in professional background, experience, expertise (including as to financial matters) and perspective with respect to the Board of Directors composition as a whole when evaluating a director nominee. The Board assesses its effectiveness in this regard as part of the annual board and director evaluation process.


Board and Director Performance Assessments

The Nominating and Corporate Governance Committee annually reviews and evaluates the performance of the Board, each Committee of the Board, and each director in order to improve the effectiveness of the Board and each Committee of the Board. The Committee assesses the contributions of the Board as a whole and each of its Committees and identifies areas in which improvements may be made. The results of the evaluations are reviewed and discussed with the Board and its Committees, and recommendations are made, as appropriate, to the Board and its Committees.

The Nominating and Corporate Governance Committee also annually reviews the individual performance and qualifications of each director who wishes to be considered for nomination for reelection to the Board.


Continuing Education

Continuing education helps our directors strengthen their skills, deepen their understanding of our business and operations and stay current with emerging issues that affect our business, governance and compensation practices. It also helps directors keep abreast of governance developments and requirements and understand the issues we face in the context of our business. To further these goals, our Board’s continuing director education policy requires directors to participate in continuing education programs and reimburses directors for expenses incurred in connection with such education programs.


Succession Planning

The Board of Directors oversees processes and procedures to provide continuity of well-qualified executive leadership and to assess whether such leadership possesses the skill and talent to execute Patterson-UTI’s long-term business strategies. The Board of Directors reviews succession planning for the Chief Executive Officer and the other senior executives tailored to reflect the Board’s standards for executive leadership and Patterson-UTI’s business strategy and vision. The succession planning addresses, among other things, (i) both current and long-term needs of Patterson-UTI and establishes a process for identifying and assessing potential internal candidates; (ii) periodic review and assessment of readiness; (iii) contingency planning for temporary absences of the Chief Executive Officer due to disability or other unexpected event; and (iv) long-term continuity planning for succession to the Chief Executive Officer position.


Political Contributions

Patterson-UTI has a policy prohibiting the contribution of company funds to political parties or organizations or to candidates for any public office or to influence the general public, or segments thereof, with respect to public elections or referenda. Patterson-UTI participates in certain trade organizations with purposes that include enhancement of the public image of our industry, education about the industry and issues that affect the industry and industry best practices and standards. Many of the trade organizations also engage in legislative or political activity related to matters that affect the industry as a whole and not a specific company. Patterson-UTI, as one of many members in various trade associations, does not direct the legislative activities of any trade organization of which it is a member.


Sustainability

We encourage you to review our latest sustainability report for information regarding our sustainability programs and initiatives. A copy of Patterson-UTI’s sustainability report can be accessed electronically in the “Sustainability” section of the Patterson-UTI website at www.patenergy.com and in print to any stockholder who requests it from the Secretary of Patterson-UTI. Nothing on our website, including our sustainability report or sections thereof, shall be deemed incorporated by reference into this proxy statement or other filings that we make with the SEC. Our sustainability goals are aspirational and may change. Statements regarding our goals are not guarantees or promises that they will be met.

Patterson-UTI’s Code of Business Conduct and Ethics and Equal Employment Opportunity and Anti-Harassment Policy prohibit discrimination or harassment of any type and afford equal employment opportunities to all employees and applicants, without regard to age, race, sex, color, religion, national origin, disability, marital status, covered veteran status, genetic information, sexual orientation, gender identity or any other characteristic protected under state, federal or local law.

PROPOSAL NO. 2

RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee appointed PricewaterhouseCoopers LLP as the independent registered public accounting firm to audit the financial statements and internal control over financial reporting of Patterson-UTI for the fiscal year ending December 31, 2026, and directed that such engagement be submitted to the stockholders of Patterson-UTI for ratification. In recommending ratification by the stockholders of such engagement, the Board of Directors is acting upon the recommendation of the Audit Committee, which has satisfied itself as to PricewaterhouseCoopers LLP’s independence, professional competence and standing. Although ratification by stockholders of the engagement of PricewaterhouseCoopers LLP is not required by Delaware corporate law or Patterson-UTI’s restated certificate of incorporation or bylaws, the Audit Committee believes a decision of this nature should be made with the consideration of Patterson-UTI’s stockholders. If the stockholders fail to ratify the appointment, the Audit Committee will reconsider whether to retain PricewaterhouseCoopers LLP and may retain that firm or another without re-submitting the matter to our stockholders. Even if the appointment is ratified, the Audit Committee may, in its discretion, direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such change would be in the best interests of Patterson-UTI and its stockholders.

It is expected that one or more representatives of PricewaterhouseCoopers LLP will be available to participate in the Meeting and will be given the opportunity to make a statement if they so desire. It also is expected that the representative(s) will be available to respond to appropriate questions from the stockholders.

The Board of Directors recommends a vote “FOR” the ratification of PricewaterhouseCoopers LLP as Patterson-UTI’s independent registered public accounting firm. Ratification of the selection of PricewaterhouseCoopers LLP requires the affirmative vote of the holders of a majority of the shares of Common Stock entitled to vote on, and voted “FOR” or “AGAINST,” the proposal. Unless you give contrary instructions in your proxy, your properly submitted proxy will be voted “FOR” such ratification. Abstentions will not be counted as votes cast “FOR” or “AGAINST” the proposal and will have no effect on the outcome of the proposal. If you do not give instructions to your brokerage firm, bank, broker-dealer, or other similar organization, the brokerage firm, bank, broker-dealer, or other similar organization is expected to be entitled, but not required, to vote your shares in its discretion and may give or authorize the giving of a proxy to vote the shares in its discretion on this proposal. Broker non-votes, if any, will not be treated as a share entitled to vote on the proposal and will have no effect on the outcome of the proposal.

PROPOSAL NO. 3

APPROVAL OF AMENDMENT TO

2021 LONG-TERM INCENTIVE PLAN


Background

The Patterson-UTI Energy, Inc. 2021 Long-Term Incentive Plan (as previously amended, the “2021 Plan”) was originally approved by Patterson-UTI's stockholders effective as of June 3, 2021. On June 8, 2023, our stockholders approved an amendment to the 2021 Plan to increase the number of shares available for issuance thereunder by 5.445 million shares. On September 1, 2023, in connection with the NexTier merger, our Board of Directors approved a second amendment to the 2021 Plan to assume 10,050,932 shares previously reserved for issuance under the NexTier Oilfield Solutions Inc. Equity and Incentive Award Plan (the “NexTier Plan” and such assumed shares, the “NexTier Pool”) as permitted by Nasdaq Rule 5635(c). On June 6, 2024, our stockholders approved a third amendment to the 2021 Plan to increase the number of shares available for issuance thereunder by 20 million shares and eliminate the NexTier Pool on a go-forward basis.

On April 1, 2026, our Board of Directors approved a fourth amendment to the 2021 Plan (the “Plan Amendment”) to increase the number of shares available for issuance under the plan by 28,900,000 shares, subject to the approval of our stockholders. No other changes to the 2021 Plan are proposed by the Plan Amendment. Participation in the 2021 Plan is broad-based, with approximately 400 employees and directors receiving grants in 2025. The increase in the overall number of shares available for issuance under the 2021 Plan is being proposed in order to preserve the flexibility of the Company to grant future awards to all of its employees, directors, consultants or advisors.

In considering the Plan Amendment, our Board of Directors considered the dilutive impact of the additional share pool request, and in particular our overhang level. Overhang is equal to the total number of shares subject to equity awards outstanding (assuming target payout of all performance units (PSUs) then outstanding) plus the total number of shares available for grant under the Company’s equity plans, divided by the sum of the total common shares outstanding, the number of shares subject to equity awards outstanding (assuming target payout of all PSUs then outstanding) and the total number of shares available for grant under the Company’s equity plans. Our total overhang was 4.8% based on our shares and shares subject to equity awards outstanding (assuming target payout of all PSUs then outstanding) as of April 1, 2026, and would increase to 11.3% upon approval of the Plan Amendment (given the additional share request). Approval of the Plan Amendment requires the affirmative vote of the holders of a majority of the shares of Common Stock that are present in person or by proxy and entitled to vote at the Meeting.

If the Plan Amendment is not approved by stockholders, the 2021 Plan will remain in effect with its current share pool. As of April 1, 2026, there were 9,372,194 shares of common stock remaining available for grant under the 2021 Plan, assuming a target payout of all PSUs then outstanding. If the Plan Amendment is not approved by stockholders, we will not be able to continue our equity-based long term incentive program once the current share pool is depleted, which would require us to increase significantly the cash component of our compensation program in order to remain competitive and adequately compensate our employees, directors, consultants and advisors.

Certain material terms of the 2021 Plan are discussed below; however, the description is subject to, and qualified by the full text of the 2021 Plan, attached hereto as Annex A, which includes the Plan Amendment highlighted in bold. Unless otherwise indicated, references to the “2021 Plan” in the following description of the material terms of the 2021 Plan reflect the 2021 Plan as amended by the Plan Amendment.


Best Practices

Independent Oversight. The Compensation Committee, composed solely of non-employee independent directors, approves all grants made to employees under the 2021 Plan; provided, however, that the Compensation Committee may delegate to the Board or any committee of the Board, to one or more executive officers or a committee of executive officers its right to grant awards under the 2021 Plan to employees who are not executive officers or directors of Patterson-UTI pursuant to such conditions or limitations as the Compensation Committee may establish. The Board of Directors approves all grants to directors under the 2021 Plan.

No Repricing of Options or SARs. The 2021 Plan prohibits the repricing and replacement of stock options or stock appreciation rights (“SARs”) at lower exercise prices unless approved by our stockholders.

No Discounted Options or SARs. Stock options and SARs may not be granted with an exercise price below the fair market value of our common stock on the date of grant.

No Dividends on Options or SARs. Dividends and dividend equivalents may not be paid or accrued on stock options or SARs.

No Dividends or Dividend Equivalents Paid on Unvested Awards. Any dividends or dividend equivalents will only be paid if and to the extent the underlying shares vest pursuant to the terms of the award.

Limited Terms for Options and SARs. Stock options and SARs granted under the 2021 Plan are generally limited to 10-year terms.

No Liberal Share Recycling. The 2021 Plan prohibits liberal share recycling. Shares delivered to Patterson-UTI or withheld to satisfy the exercise price of a stock option or SAR or withholding tax obligations on any award, shares not issued in the net settlement of a stock-settled SAR, and shares repurchased on the open market with the proceeds of a stock option exercise will not again be made available for grant under the 2021 Plan.

No “Evergreen” Provision. Shares authorized for issuance under the 2021 Plan will not be replenished automatically. Any additional shares to be issued over and above the current share pool, as increased by the Plan Amendment, will require further stockholder approval.

No Tax Gross-Ups. The Compensation Committee does not provide tax gross-ups in connection with awards under the 2021 Plan.

Annual Limitation on Director Compensation. The total compensation paid to each non-employee director for their service as such, whether in cash or in equity awards under the 2021 Plan (based on the grant date fair value of any such awards) during a single fiscal year may not exceed $750,000 (or $1,000,000 for any fiscal year in which the non-employee director is first appointed to the Board or any fiscal year in which the non-employee director serves as chairman or lead director).

Recoupment. Awards granted under the 2021 Plan are subject to the Patterson-UTI Energy, Inc. Clawback Policy and will be subject to any other clawback policy adopted by us. In addition, if we are required to prepare an accounting restatement due to the material noncompliance of Patterson-UTI, as a result of misconduct, with any financial reporting requirement, the 2021 Plan requires recoupment where required under Section 304 of the Sarbanes-Oxley Act of 2002 and permits recoupment from any participant who engaged in such misconduct. See the description of our current Clawback policy below under “Clawback Policy”.

Minimum Vesting. Subject to a 5% carve-out, all awards are subject to a minimum vesting period of one year from the date of grant, except in the case of substitute awards, awards delivered in lieu of fully-vested cash obligations, certain awards to directors that vest in connection with an annual meeting, and permitted accelerations of awards, such as in connection with a holder's retirement, death or disability or in the event of a change in control.


Burn Rate

Our Board and Compensation Committee are committed to using equity awards prudently and consider the dilutive impact of annual grants on our stockholders. Set forth below is information on the awards granted or earned and our burn rate for the years 2023-2025 under our previous equity compensation plan, the Amended and Restated 2014 Long-Term Incentive Plan, as amended (the “2014 Plan”), and the 2021 Plan:


	A	B	C	D	E	F	G
Fiscal Year	Stock Options Granted (1)	Time-Based RSUs Granted (1)	PSUs / Performance-Based RSUs Granted (1)(2)	Actual PSUs and Performance- Based RSUs Earned (1)	Total (1)(3)	Weighted Average # of Common Shares Outstanding	Burn Rate (4)
2025	—	4,448,229	743,800	—	8,896,458	383,465,285	2.32	%
2024	—	3,113,411	875,100	764,242	7,755,306	397,195,631	1.95	%
2023	—	1,840,861	796,976	1,001,000	5,683,722	280,061,025	2.03	%
Average Three-Year Burn Rate (2023-2025)							2.10	%

_____________

(1)Excludes 652,573 stock options and 7,438,031 time-based RSUs outstanding under the NexTier Plan and the NexTier Oilfield Solutions Inc. (Former C&J Energy) Management Incentive Plan (the “Former C&J Energy Plan”), which we assumed in 2023 in connection with the NexTier Merger. All of these assumed awards had been previously granted by NexTier or its affiliates in periods prior to the NexTier merger. Excludes 619,417 cash-settled RSUs granted in the 2025 fiscal year.

(2)Reflects target number of PSUs granted in applicable fiscal year. Excludes 743,800 cash-settled PSUs granted in 2025 fiscal year.

(3)Total number of shares in a particular fiscal year includes all time-based awards granted during such fiscal year, and all PSUs and RSUs for which the performance criteria was certified as attained and earned during such fiscal year. In light of the fungible ratio share counting provisions of both the 2014 Plan and the 2021 Plan, RSUs and PSUs are counted as two shares in the Total amount. Accordingly, the number in this “Total” column for a particular fiscal year is derived as follows: (i) column A (zero for each year); plus (ii) column B, times two, plus (iii) column D, times two.

(4)PSUs granted in the applicable fiscal year and not yet earned are excluded from the calculation of burn rate.


Description of the 2021 Plan

The primary objective of the 2021 Plan is to assist Patterson-UTI and its subsidiaries in attracting and retaining selected individuals to serve as directors, employees, consultants and advisors of Patterson-UTI who are expected to contribute to its success and achieve long-term objectives that will inure to the benefit of its stockholders through the additional incentives inherent in awards under the 2021 Plan. The 2021 Plan provides for the granting of incentive and non-qualified stock options, tandem and freestanding stock appreciation rights, restricted stock awards, other stock unit awards, performance shares, performance units and dividend equivalents. Certain awards under the 2021 Plan may be paid in cash or Common Stock, as determined by the Compensation Committee. The Compensation Committee has exclusive authority to select the participants to whom awards may be granted, and to determine the type, size and terms of each award, subject to the limitations set forth in the 2021 Plan. The Compensation Committee will also make all determinations that it decides are necessary or desirable in the interpretation and administration of the 2021 Plan. In addition, the Compensation Committee may, if consistent with applicable rules, regulations and Nasdaq requirements, delegate to a committee of one or more directors or to one or more executive officers the right to grant, cancel and suspend awards to employees who are not directors or executive officers of Patterson-UTI.

As of April 1, 2026, the equity awards outstanding under the NexTier Plan, the Former C&J Energy Plan, the 2014 Plan, and the 2021 Plan, were as follows (1):


Options outstanding (2)			1,137,205
Full-value awards outstanding (3) (4)			8,832,248
Weighted-average exercise price of outstanding options			$23.56
Weighted-average remaining contractual term of outstanding options			0.45
Shares available for grant under the 2021 Plan (4) (5)			9,372,194
Shares of Common Stock Outstanding			379,602,464

_____________

(1)This table excludes the 28,900,000 shares requested pursuant to the Plan Amendment.

(2)Includes 406,405 options outstanding under the Former C&J Energy Plan (with a weighted average exercise price of $32.50 and weighted average remaining contractual term of 1.08 years) and 730,800 options outstanding under the 2014 Plan (with a weighted average exercise price of $18.59 and weighted average remaining contractual term of 0.11 years).

(3)Includes 9,076 RSUs under the NexTier Plan and 6,608,472 RSUs and 2,214,700 PSUs (at target) under the 2021 Plan. No RSUs and PSUs are outstanding under the 2014 Plan.

(4)Under the fungible counting provisions of the 2021 Plan, full-value awards count as two shares.

(5)No shares remain available for grant under the 2014 Plan, the NexTier Plan or the Former C&J Energy Plan.


General Terms

•Subject to adjustment in the event of certain corporate transactions, the aggregate number of shares of Common Stock authorized for grant under the 2021 Plan (after giving effect to the Plan Amendment) is 67,812,480, which includes the 38,912,480 shares previously authorized for issuance under the 2021 Plan. Shares that are subject to options or SARs count as one share of Common Stock against this aggregate limit. Shares that are subject to awards other than options and SARS count as two shares of Common Stock against this aggregate limit. The closing price of a share of Common Stock on April 1, 2026 was $10.35.

•The maximum number of shares that may be issued pursuant to awards under the 2021 Plan (after giving effect to the Plan Amendment) will be the sum of 28,900,000 new shares requested plus 9,372,194 currently available shares, less one share for each option and SAR award (and less two shares for all other award types) subject to any equity award granted under the current plan after April 1, 2026, until the proposed Plan Amendment’s approval date (provided that, in no event shall the number of shares subject to any equity award granted under the 2021 Plan after April 1, 2026 and prior to the Plan Amendment approval date exceed 9,372,194 shares).

•In addition to the above, if an award granted under the 2021 Plan or the 2014 Plan expires, is forfeited, is settled in cash or otherwise terminates without the issuance of all or a portion of the shares of Common Stock subject to the award, the shares allocable to the expired, forfeited, cash settled, or terminated portion of the award will be available for awards again under the 2021 Plan. Consistent with the fungible counting provisions of both the 2014 and 2021 Plans, any share of Common Stock that again becomes available for grant under the 2021 Plan will be added back as one share if the share was subject to an option or SAR, and as two shares if the share was subject to an award other than an option or SAR.

•If any shares subject to an award are used to exercise options, are not issued upon the settlement of a SAR, are withheld by Patterson-UTI for income or employment taxes on the exercise of an option or SAR or the vesting or settlement of any other award type, or are re-purchased on the open market with the exercise price for an option, such shares will not become available for grant under the 2021 Plan.

•With respect to awards to participants other than directors, the 2021 Plan is administered by the Compensation Committee of Patterson-UTI’s Board of Directors, which comprises exclusively non-employee independent directors. With respect to awards to directors, the 2021 Plan is administered by the Board of Directors.

•Directors, employees, including officers, consultants and advisors are eligible for awards under the 2021 Plan. As of April 1, 2026, approximately 7,800 employees, nine directors and an indeterminate number of consultants and advisors would be eligible for awards under the 2021 Plan, although Patterson-UTI has not historically granted awards under its long-term incentive plans to consultants or advisors.

•The Board of Directors, at any time, may amend the terms of the 2021 Plan, subject to the stockholder approval requirements of the Nasdaq Stock Market and other rules and regulations applicable to Patterson-UTI. Generally, the 2021 Plan also may not be amended without stockholder approval to permit the repricing of options or SARs or to extend the generally applicable maximum 10-year term applicable to options and SARs.

•Except in connection with certain corporate transactions involving Patterson-UTI, the terms of outstanding options or SARs may not be amended to reduce the applicable exercise price and outstanding options and SARs may not be cancelled in exchange for cash, other awards or options or SARs with an exercise price that is less than the exercise price of the original options or SARs, in each case without stockholder approval.

•Subject to the exceptions in this bullet, awards may not be sold, assigned, transferred, pledged or otherwise encumbered, other than by will or the laws of descent and distribution or pursuant to a domestic relations order, as determined by the Compensation Committee, and awards may be exercised during the life of the participant only by the participant or the participant’s guardian or legal representative. Notwithstanding the foregoing, a participant may assign or transfer an award other than an incentive stock option with the consent of the Compensation Committee (i) for charitable donations; (ii) to the participant’s spouse, children or grandchildren (including any adopted and stepchildren and grandchildren), or (iii) to a trust for the benefit of one or more of the participants or the persons referred to in clause (ii); provided that certain administrative conditions are met. For the avoidance of doubt, awards (other than fully vested and unrestricted shares of Common Stock) may not be transferred to a third party for monetary value.

•Except with respect to 5% of the shares authorized for grant under the 2021 Plan, no award may vest prior to the first anniversary of the grant date other than in the case of substitute awards, awards delivered in lieu of fully-vested cash obligations, certain awards to directors that vest in connection with an annual meeting, and accelerations of awards such as in connection with a holder’s retirement, death or disability or in the event of a change in control.

•No awards may be granted under the 2021 Plan after April 9, 2031, the tenth anniversary of the original effective date of the 2021 Plan.


Options

•The vesting schedule for options is set by the Compensation Committee, subject to the minimum vesting requirements of the 2021 Plan.

•The term of options is set by the Compensation Committee, but may be no longer than 10 years other than as a result of any extension of the term in compliance with applicable law as provided in an award agreement.

•The exercise price for options may be paid in cash, with previously acquired shares of Common Stock, or by other means approved by the Compensation Committee.

•All options granted under the 2021 Plan (other than substitute awards) are granted with an exercise price equal to or greater than the fair market value of the Common Stock at the time the option is granted.


SARs

•SARs may be granted alone or in connection with the grant of any option. A SAR entitles a participant to surrender any then exercisable portion of the SAR and, if applicable, the related option, in exchange for an amount equal to the product of (i) the excess of the fair market value of a share of Common Stock on the date of surrender over the fair market value of a share of Common Stock on the date that the SAR was granted, or, if the SAR is related to an option, the per share exercise price of the option, multiplied by (ii) the number of shares of Common Stock subject to the SAR and being surrendered.

•SARs granted alone may be exercised at such times and be subject to such terms and conditions as the Compensation Committee may impose. SARs that are granted in tandem with options may be exercised only on the surrender of the right to purchase an equivalent number of shares under the related options and may be exercised only with respect to the shares of Common Stock for which the related options are then exercisable.

•The vesting schedule for SARs is set by the Compensation Committee, subject to the minimum vesting requirements of the 2021 Plan.

•The term of SARs under the 2021 Plan may be no longer than 10 years other than as a result of any extension of the term in compliance with applicable law as provided in an award agreement.

•Payment on exercise of a SAR shall be, in the discretion of the Compensation Committee, shares of Common Stock, cash, or a combination of shares of Common Stock and cash.

•All SARs granted under the 2021 Plan (other than substitute awards) are granted with an exercise price equal to or greater than the fair market value of the Common Stock at the time the SAR is granted.


Restricted Stock Awards

•The Compensation Committee determines the material terms of restricted stock awards, including the price, if any, to be paid by the recipient, and, subject to the minimum vesting requirements of the 2021 Plan, the vesting schedule and conditions, which may include the attainment of specified performance objectives.

•Beginning on the date of grant, a participant receiving a restricted stock award will become a stockholder of Patterson-UTI with respect to all shares of Common Stock subject to the restricted stock award, which, unless the Committee determines otherwise at the time of the grant, includes the right to vote the shares and receive dividends in respect of the shares; provided, however, that any dividends with respect to any restricted stock award as to which the restrictions have not yet lapsed shall be subject to the same restrictions as such restricted stock award.


Other Stock Unit Awards

•The Compensation Committee may grant other stock unit awards under the 2021 Plan, which have a value equal to an identical number of shares of Common Stock. Other stock unit awards may also be a form of payment for other awards granted under the 2021 Plan and other earned cash-based incentive compensation.

•The payment of other stock units may be in cash, shares of Common Stock, other property, or any combination of the foregoing, and may be made in a lump sum or, in accordance with procedures established by the Compensation Committee, on a deferred basis subject to the requirements of section 409A of the Internal Revenue Code (the "Code").

•The vesting schedule for other stock unit awards is set by the Compensation Committee, subject to the minimum vesting requirements of the 2021 Plan.


Dividend Equivalent Rights

•The Compensation Committee may grant dividend equivalent rights either in connection with awards or as separate awards under the 2021 Plan.

•Amounts payable in respect of dividend equivalent rights will not be paid until the vesting, payment, settlement or other lapse of restrictions of the award to which the dividend equivalent rights relate, including with respect to any performance conditions applicable to the underlying award.

•No award of options or SARs will have dividend equivalent rights.


Performance Awards

•Performance awards are payable in cash, shares of Common Stock, other property, or a combination of the foregoing, and may be paid in a lump sum, in installments, or on a deferred basis in accordance with procedures established by the Compensation Committee.

•The Compensation Committee determines the material terms of the performance awards, including a performance period over which the performance goal of such award shall be measured. Performance awards are subject to the one year minimum vesting requirements of the 2021 Plan.


Deferrals

•The Compensation Committee may require or permit a participant to defer the receipt of cash or shares pursuant to any awards under the 2021 Plan. Any deferral permitted under the 2021 Plan will be administered in a manner that is intended to comply with section 409A of the Code.


Effect of Certain Transactions and Change of Control

The Compensation Committee, in its discretion, may determine that, unless otherwise specifically set forth in an award agreement or other agreement applicable to any award, upon a change of control (as defined in the 2021 Plan):

•awards outstanding as of the date of the change of control immediately vest and become free of all restrictions and limitations and, to the extent applicable, become fully exercisable and/or immediately settled or distributed;

•each option and SAR shall terminate within a specified period of days after notice to the participant;

•each participant shall receive, with respect to each share subject to an award, an amount equal to the excess of the fair market value of such share immediately prior to the occurrence of the change of control over the exercise price per share, if applicable, of such award, with such payment being made in one or more kinds of stock or property or a combination of stock or property;

•each option and SAR outstanding on the date of the change of control may be cancelled and terminated without payment if the fair market value of a share of Common Stock on the date of the change of control is less than the per share exercise price of the option or SAR; or

•such other additional adjustments or benefits as the Compensation Committee deems appropriate shall apply.

Further, in the event of changes in the capital or corporate structure of Patterson-UTI due to events such as recapitalization, stock split, merger, spin-off, joint venture, subsidiary or division sale or similar transaction, that affect the shares of Common Stock, the Compensation Committee, in its sole discretion, may determine that it is equitable or appropriate to make adjustments or substitutions to the 2021 Plan or outstanding options and awards, including to the number, class, kind and option or exercise price or securities subject to awards and to the terms and conditions of awards (including any applicable performance targets or criteria with respect thereto).


Federal Income Tax Consequences

The following discussion summarizes certain U.S. federal income tax consequences of the grant and receipt of awards pursuant to the 2021 Plan under the law as in effect on the date of this proxy statement. The rules governing the tax treatment of such awards are quite technical, so the following discussion of tax consequences is necessarily general in nature and is not complete. In addition, statutory provisions are subject to change, as are their interpretations, and their application may vary in individual circumstances. This summary does not purport to cover all federal employment tax, estate tax, or other federal tax consequences associated with the 2021 Plan, nor does it address state, local, or non-U.S. tax consequences. As such, we recommend that all participants consult their own tax advisor concerning the tax implications of awards granted under the 2021 Plan.

ISOs. In general, a participant will not recognize income upon the grant or exercise of an ISO. However, upon the exercise of an ISO, the excess of the fair market value of the shares of Common Stock received upon the exercise of the ISO over the exercise price will increase the employee’s alternative minimum taxable income, which may cause the employee to incur the alternative minimum tax. Subject to certain exceptions for death or disability, if a participant exercises an ISO more than three months after termination of employment, the exercise of the option will be taxed as the exercise of a NQSO, as described below.

The general rule is that gain or loss from the sale or exchange of shares acquired on the exercise of an ISO will be treated as capital gain or loss. However, if shares acquired upon the exercise of an ISO are disposed of within two years from the date of grant or within one year after exercise (a “disqualifying disposition”), the participant generally will recognize ordinary income in the year of disposition in an amount equal to the fair market value of the shares at the time of exercise (or, if less, the amount realized on the disposition of the shares) less the exercise price. Any further gain (or loss) realized by the participant generally will be taxed as short- or long-term capital gain (or loss) depending on the holding period.

NQSOs, SARs, Performance Award, Other Stock Unit Award and Dividend Equivalents. A participant generally is not required to recognize income on the grant of a NQSO, SAR, performance award or other stock unit award. Instead, ordinary income generally is required to be recognized on the date the NQSO or SAR is exercised, or in the case of performance awards or other stock unit awards, upon the issuance of shares and/or the payment of cash pursuant to the terms of the award. In general, the amount of ordinary income required to be recognized is, (a) in

the case of a NQSO or a SAR, an amount equal to the excess, if any, of the fair market value of the shares on the exercise date over the exercise price, and (b) in the case of performance awards or other stock unit awards, the amount of cash and/or the fair market value of any shares received in respect thereof, plus the amount of taxes withheld from such amounts. Ordinary income is recognized upon the payment of dividend equivalents, if any, granted with respect to performance awards, other stock unit awards or as separate awards.

Restricted Common Stock. Unless a participant who receives an award of restricted Common Stock makes an election under section 83(b) of the Code as described below, the participant generally is not required to recognize ordinary income on the grant of restricted Common Stock. Instead, on the date the shares vest (i.e., become transferable and no longer subject to forfeiture), the participant will be required to recognize ordinary income in an amount equal to the excess, if any, of the fair market value of the shares on such date over the amount, if any, paid for such shares. If a section 83(b) election has not been made, any dividends received with respect to restricted Common Stock that are subject at that time to a risk of forfeiture or restrictions on transfer generally will be treated as compensation that is taxable as ordinary income to the recipient. If a participant makes a section 83(b) election within 30 days following the date of transfer of the restricted Common Stock, the participant will recognize ordinary income on the date the shares are granted in an amount equal to the excess, if any, of the fair market value of the shares on the date of award over the amount, if any, paid for such shares. In such case, the participant will not be required to recognize additional ordinary income when the shares vest. However, if the shares are later forfeited, a loss can only be recognized up to the amount the participant paid, if any, for the shares.

Gain or Loss on Sale or Exchange of Shares. In general, gain or loss from the sale or exchange of shares granted or awarded under the 2021 Plan will be treated as capital gain or loss, provided that the shares are held as capital assets at the time of the sale or exchange. However, if certain holding period requirements are not satisfied at the time of a sale or exchange of shares acquired upon exercise of an ISO (a “disqualifying disposition,” see above), a participant generally will be required to recognize ordinary income upon such disposition.

Deductibility by Patterson-UTI. To the extent that a participant recognizes ordinary income in the circumstances described above, Patterson-UTI or the subsidiary for which the participant performs services will be entitled to a corresponding deduction, provided that, among other things, the income meets the test of reasonableness, is an ordinary and necessary business expense, is not an “excess parachute payment” within the meaning of section 280G of the Code (see Parachute Payments below) and is not disallowed by the $1,000,000 limitation on certain executive compensation under section 162(m) of the Code. In general, under section 162(m) of the Code, remuneration paid by a public corporation to certain “covered employees” (which includes any individual who serves as chief executive officer, chief financial officer or one of the other three most highly compensated executive officers for 2017 or any subsequent calendar year and, commencing in 2027, certain other highly paid employees) is not deductible to the extent it exceeds $1 million for any year. It is expected that compensation deductions for any covered employee with respect to awards under the 2021 Plan will be subject to a $1 million annual deduction limitation. The Compensation Committee may grant awards under the 2021 Plan or otherwise that are or may become non-deductible when it believes doing so is in the best interests of the Company and its stockholders.

Parachute Payments. The acceleration of the exercisability or the vesting of an award upon the occurrence of a change in control may result in an “excess parachute payment” within the meaning of section 280G of the Code. A “parachute payment” occurs when an employee receives payments contingent upon a change in control that exceed an amount equal to three times his or her “base amount.” The term “base amount” generally means the average annual compensation paid to such employee during the five calendar years preceding the calendar year in which the change in control occurs. An “excess parachute payment” is the excess of all parachute payments made to the employee on account of a change in control over the employee’s base amount. If any amount received by an employee is characterized as an excess parachute payment, the employee is subject to a 20% excise tax on the amount of the excess, and Patterson-UTI is denied a tax deduction with respect to such excess.

Withholding. Awards under the 2021 Plan may be subject to tax withholding. Where an award results in income subject to withholding, Patterson-UTI may require the participant to remit the withholding amount to Patterson-UTI or cause shares of Common Stock to be withheld or sold in order to satisfy the tax withholding obligations.

Section 409A. Section 409A of the Code generally provides that any deferred compensation arrangement must satisfy specific requirements, both in operation and in form, regarding (i) the timing of payment, (ii) the election of deferrals and (iii) restrictions on the acceleration of payment. Failure to comply with section 409A may result in the early taxation (plus interest) to the participant of deferred compensation and the imposition of a 20% tax on the participant of the deferred amounts included in the participant’s income. Patterson-UTI intends to structure awards

under the 2021 Plan in a manner that is designed to be exempt from or comply with section 409A, but does not guarantee such treatment.


Existing Plan Benefits

Any future awards granted to employees, consultants, advisors and non-employee directors under the 2021 Plan are subject to the discretion of the Compensation Committee or the Board, as applicable, and therefore, are not determinable at this time. The "Grants of Plan-Based Awards" table below sets forth information with respect to prior awards granted to our named executive officers under the 2021 Plan during 2025. As of April 1, 2026, no stock options or SARs have been granted under the 2021 Plan, and no awards have been granted that are contingent on the approval of the 2021 Plan.

In addition, our non-employee directors are expected to receive annual grants on January 1 of each year consistent with the equity grants described below under “Director Compensation”. Because future awards are at the discretion of the Compensation Committee and the Board, the number of shares subject to future awards could increase or decrease and the type and terms of future awards could change as well, all without the need for future stockholder approval. If the Plan Amendment is approved, Patterson-UTI intends to thereafter register the additional shares authorized for grant under the 2021 Plan, as amended, on a Registration Statement on Form S-8 filed with the Securities and Exchange Commission.

The Board of Directors recommends a vote “FOR” the approval of the Plan Amendment. Approval of the proposal requires the affirmative vote of the holders of a majority of the shares of Common Stock present in person or by proxy and entitled to vote on the proposal. Unless you give contrary instructions in your proxy, your properly submitted proxy will be voted “FOR” approval of the proposal. Abstentions will be counted as shares entitled to vote on the proposal and will have the same effect as a vote “AGAINST” the proposal. A broker non-vote will not be treated as a share entitled to vote on the proposal and will have no effect on the outcome of the proposal. Brokerage firms, banks, broker-dealers, and other similar organizations do not have authority to vote on this proposal without instructions from the beneficial owner.

PROPOSAL NO. 4

ADVISORY APPROVAL OF EXECUTIVE COMPENSATION

In accordance with Section 14A of the Exchange Act, the Board of Directors is asking stockholders to approve a non-binding, advisory resolution to approve the compensation of Patterson-UTI’s executive officers who are named in the Summary Compensation Table appearing in this proxy statement (the “Named Executive Officers”). The compensation of the Named Executive Officers is described in the “Compensation Discussion and Analysis” and “Executive Compensation” sections of this proxy statement.

For a discussion of our stockholder engagement and compensation program alignment with stockholder interests, please see “Compensation Discussion and Analysis— Aligning Compensation Programs with Stockholder Interests.”

The compensation program for the Named Executive Officers is designed to attract and retain highly qualified individuals and to motivate and reward them for performance that benefits Patterson-UTI and its stockholders. The Compensation Committee and the Board of Directors believe that the policies and procedures detailed in the “Compensation Discussion and Analysis” achieve these goals by, among other things:

•providing a mix of short-term compensation in the form of base salary and annual cash incentive bonuses and long-term compensation in the form of restricted stock units, performance units, and, in some years, restricted stock, stock options and phantom units, which strikes a balance between offering competitive compensation packages and aligning compensation with long-term growth and creating value for stockholders;

•emphasizing variable equity and cash compensation to link realized compensation to performance;

•reviewing annual base salaries, in part, based on Patterson-UTI’s financial results and position and performance compared to similarly situated companies;

•providing performance-based annual cash incentive bonuses designed to place a meaningful portion of total compensation at risk;

•awarding long-term equity incentives whose value is tied to the achievement of certain performance goals and/or an increase in the price of the Common Stock;

•awarding long-term equity incentives that generally vest over periods of three years; and

•maintaining stock ownership requirements.

The Board of Directors is asking stockholders to approve the following non-binding, advisory resolution at the Meeting:

“RESOLVED, that the stockholders of Patterson-UTI Energy, Inc. (the “Company”) approve, on an advisory basis, the compensation of the Company’s Named Executive Officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the compensation tables and other narrative discussion in the Proxy Statement for the 2026 Annual Meeting of Stockholders of the Company.”

This advisory resolution, commonly referred to as a “say-on-pay” resolution, is non-binding on the Board of Directors. Although non-binding, the Board of Directors and the Compensation Committee value the views of Patterson-UTI’s stockholders and will review and consider the voting results when (i) evaluating the effectiveness of Patterson-UTI’s compensation policies and practices and (ii) making future compensation decisions for the Named Executive Officers. As recommended by our stockholders at the 2023 annual meeting, Patterson-UTI currently holds an annual “say-on-pay” vote and thus, unless the Company changes its policy, expects that the next such vote after the 2026 annual meeting will be held at the 2027 annual meeting of stockholders.

The Board of Directors recommends a vote “FOR” the approval of the advisory resolution on executive compensation. Approval of the advisory resolution requires the affirmative vote of the holders of a majority of the shares of Common Stock entitled to vote on, and voted “FOR” or “AGAINST,” the proposal. Unless you give contrary instructions in your proxy, your properly submitted proxy will be voted “FOR” approval of the proposal. Abstentions will not be counted as votes cast “FOR” or “AGAINST” the proposal and will have no effect on the outcome of the proposal. A broker non-vote will not be treated as a vote cast “FOR” or “AGAINST” the proposal and will have no effect on the outcome of the proposal.

Aligning Compensation Programs with Stockholder Interests


Realized Compensation Closely Aligns with Performance

The oilfield services industry has experienced challenging market conditions in recent years due to various macro factors, including commodity prices, an uncertain geopolitical environment, changes to international tariffs and trade policies, inflationary pressures, the economic environment in the United States and elsewhere, customer consolidation and increased focus by exploration and production companies and service companies on capital returns. These conditions have collectively contributed to a decline in industry activity and our share price in recent years.

The Board of Directors and the Compensation Committee recognize the importance of aligning our compensation program with the Company’s performance and stockholder returns. Our executive compensation program emphasizes variable equity and cash compensation to link our executives’ realized compensation to Company performance, and a significant portion of our executive compensation is comprised of long-term equity

incentives whose value is tied to the achievement of certain operational and financial performance goals and/or an increase in the price of our Common Stock.

These design practices reinforce a strong pay-for-performance philosophy and closely align our compensation program with the creation of long-term stockholder value. As a result, our NEOs' realized compensation meaningfully tracks our stock price performance. As illustrated in the chart below, over the past three years our CEO's realized pay has declined significantly in step with our stock price performance, underscoring the direct alignment between executive compensation and stockholder outcomes and demonstrating the rigor of our goal-setting and performance assessment processes.
