2025 Strategic Priorities

As we began 2025 , we identified the following focus areas in our Annual Report on Form 10-K for the fiscal year ended

December 31, 2024 (2024 Form 10-K) :

• International: Increase international growth in directional

drilling, unconventionals, well intervention, and artificial

lift business.

• North America: Maximize value by, among other things,

utilizing our Zeus electric fracturing platform and our

iCruise rotary steerable systems.

• Digital: Continue to drive differentiation and efficiencies

through the deployment of digital and automation

technologies, both internally and for our customers.

• Capital efficiency: Maintain our capital expenditures at

approximately 6% of revenue while utilizing technology

and targeted process improvements to enhance

utilization of existing capital.

• Shareholder returns: Return over 50% of annual free

cash flow (1) to shareholders through dividends and share

repurchases.

• Advance a sustainable energy future: Continue to

develop technologies and solutions to help lower our

customers ’ and our emissions intensity, participate in

carbon capture, utilization, and storage, and geothermal

projects globally, and support Halliburton Labs early-

stage company participants.

(1) Free cash flow is a non-GAAP measure which is calculated as “Total cash flows provided by operating activities (operating cash flow)”

less “capital expenditures” plus “proceeds from the sale of property, plant, and equipment.” Management considers free cash flow an

important indicator of the company ’ s liquidity , as it helps both investors and management evaluate the business’s ability to generate cash.

See Appendix D for reconciliation to U.S. GAAP.

2025 Performance Overview (page 5 0 )

Our success throughout 2025 was a direct result of the hard

work and dedication of our employees with relentless focus

on safety, operational execution, customer collaboration,

and service quality performance. In 2025, Halliburton

delivered solid results through clear strategy and disciplined

execution. We generated $22.2 billion in total company

revenue. We achieved another year of strong free cash flow

through cost and capital discipline. Here are the highlights

for 2025 :

• Financial: Our total revenue decreased 3% in 2025 as

compared to 2024. Our international revenue decreased

2% and our North America revenue decreased 6% in

2025 compared to 2024. Overall, our Completion and

Production and Drilling and Evaluation operating

segments finished the year with 17% and 15% operating

margins, respectively. We generated $2.9 billion of cash

flows from operations and retired $382 million of our

3.8% notes due November 2025.

• Capital efficiency: We developed technologies and

made strategic choices that kept our capital expenditures

at approximately 6% of revenue, which matched our

target.

• Shareholder returns: We returned $1.6 billion of capital

to shareholders through dividends and share

repurchases, which is consistent with our capital returns

framework.

• Sustainability: We continued progress toward a

sustainable energy future by expanding Halliburton Labs ’

38 participant and alumni organizations, and achieving

the milestone of 50% of our North American fracturing

fleet transitioned to Zeus electric pumps .

Information contained on or accessible from our website or any other website is not incorporated by reference into and

should not be considered part of this proxy statement.

Code of Business Conduct

Our Code of Business Conduct, which applies to all of our Directors and employees, and serves as the code of ethics for our

principal executive officer, principal financial officer, principal accounting officer or controller, and other persons performing

similar functions, is available on our website. Any waivers to our Code of Business Conduct for our Directors or executive

officers can only be made by our Audit Committee. There were no waivers of the Code of Business Conduct in 2025 . Any

amendments to our Code of Business Conduct or any waivers from provisions of our Code of Business Conduct granted to

the specified officers above are also disclosed on our website at www.halliburton.com.

Related Persons Transactions Policy

Our Board has adopted a written policy governing related persons transactions as part of the Board’s commitment to good

governance and independent oversight. The policy covers transactions involving any of our Directors, executive officers,

nominees for Director, greater than 5% shareholders, or any of their immediate family members, among others.

The types of transactions covered by this policy are transactions, arrangements, or relationships, or any series of similar

transactions, arrangements, or relationships, including any indebtedness or guarantee of indebtedness, in which (i) we or

any of our subsidiaries were or will be a participant, (ii) the aggregate amount involved exceeds $120,000 in any calendar

year, and (iii) any related person had, has, or will have a direct or indirect material interest.

Under the policy, we generally only enter into or ratify related persons transactions when the Audit Committee determines

such transactions are in our best interests and the best interests of our shareholders. In determining whether to approve or

ratify a related persons transaction, the Audit Committee will consider the following factors and other factors it deems

appropriate:

• whether the related persons transaction is on terms comparable to terms generally available with an unaffiliated third party

under the same or similar circumstances;

• the benefits of the transaction to the Company;

HALLIBURTON 2026 Proxy Statement 7

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

• whether there are alternative sources for the subject matter of the transaction.

The Audit Committee reviewed the employment relationship of Phillip Spoelker, who is the brother of Ms. Stephanie

Holzhauser, the Company’s Chief Accounting Officer. Mr. Spoelker is employed by Halliburton in a non-executive officer

position and received total compensation of approximately $168,000 from January 1, 2025 through December 31, 2025 . Mr.

Spoelker’s compensation was established by Halliburton in accordance with its compensation practices applicable to

employees with comparable qualifications and responsibilities and holding similar positions and is commensurate with that of

his peers in Halliburton’s compensation framework.

Insider Trading Policies

The Company maintains polices titled “ Use of Material Nonpublic Information, Securities Trading Windows, and Hedging

and Pledging of Company Securities ” and “ Securities Trading of Company Securities by the Company ” governing the

purchase, sale, and other dispositions of Halliburton securities by Directors, officers, employees, or the Company itself that

are reasonably designed to promote compliance with insider trading laws, rules, and regulations of the U.S. Securities and

Exchange Commission (SEC), and the New York Stock Exchange listing standards applicable to the Company. Copies of

these policies were filed as Exhibit 19.1 and 19.2 to the 2024 Form 10-K.

The Board of Directors and Standing

Committees of Directors

The Board has the following standing Committees: Audit; Compensation; Health, Safety and Environment; and Nominating

and Corporate Governance. Each standing Committee is comprised of Directors who, in the business judgment of the

Board, are independent, after considering all relevant facts and circumstances, including the independence standards set

forth in our Corporate Governance Guidelines.

Our Corporate Governance Guidelines provide that the independence of each Director will be determined by the Board in

the exercise of its business judgment and considering the applicable rules and regulations of the SEC , and the New York

Stock Exchange and the New York Stock Exchange Texas (collectively, the NYSE).

In connection with its independence determination, the Board considered that we utilize health insurance services of Blue

Cross Blue Shield, a subsidiary of Health Care Service Corporation, of which Mr. Smith is the Chairman, President and Chief

Executive Officer, in the ordinary course of business . The Board concluded that the relationship was on market terms, not

material, and did not affect the independence of Mr. Smith.

The Board also considered that Mr. Leach serves on the Board of ConocoPhillips and previously served as an advisor to the

CEO of ConocoPhillips. The Board concluded that Mr. Leach’s participation on the ConocoPhillips board does not affect the

independence of Mr. Leach.

Board Leadership

Our Board believes that it is important to maintain flexibility to determine the appropriate leadership of the Board and

whether the roles of Chairman and Chief Executive Officer should be combined or separate. Our Corporate Governance

Guidelines provide that the Board consider annually whether it is appropriate for the same individual to fill both of those

roles. When making that determination, the Board considers issues such as industry and financial expertise, in-depth

knowledge of Halliburton and its business, and succession planning. In 2025 , the Board evaluated and decided that a

combined leadership role would continue to best serve the Company and its shareholders. The Board believes that Jeffrey

A. Miller, our Chairman, President and Chief Executive Officer, with his industry expertise, financial expertise, and in-depth

knowledge of Halliburton and its business, is the correct person to fill both roles. The Board also believes that Mr. Miller is

best suited to lead the Board’s discussion and evaluation of the Company’s business, financial, and health, safety,

environment, and sustainability strategy and performance. With the exception of Mr. Miller and Mr. Slocum, the Board is

composed of independent Directors.

8 HALLIBURTON 2026 Proxy Statement www.halliburton.com

In the Board’s consideration of the appropriate leadership structure, independence and objectivity are primary areas of

focus, and are supported by the appointment of a Lead Independent Director whose role and responsibilities are set forth in

the Lead Independent Director Charter adopted by the Board. Robert A. Malone is our Lead Independent Director. The Lead

Independent Director’s responsibilities include the following:

●	liaises between the independent Directors and the Chairman	●	participates in shareholder engagement
●	approves agendas for Board meetings and ensures the agendas provide opportunities for the Board to provide input on the Company’s business strategy and management’s execution of that strategy	●	advises management on and approves information sent to the Board and approves schedules for meetings of the Board
●	presides over meetings and executive sessions of the independent Directors	●	authorizes the retention of outside advisors and consultants who report directly to the Board
●	leads the Board’s annual evaluation of the Chief Executive Officer	●	schedules meetings of the independent Directors as appropriate
●	participates in efforts to identify and recruit candidates for Board membership

Our Lead Independent Director Charter is available on our website at www.halliburton.com .

Board and Committee Oversight

Governance Oversight

The Halliburton Board of Directors Nominating and Corporate Governance Committee conducts general oversight for

Halliburton’s corporate strategy and financial, operational, market, political, cybersecurity, artificial intelligence, sustainability,

and other risks inherent in Halliburton’s business. However, each Board Committee is responsible for different aspects of

oversight (as outlined in each Committee’s charter).

By regularly engaging with shareholders and other outside experts, the Board can more effectively prioritize relevant key

matters in the Company’s overall corporate strategy and enterprise risk profile. At least twice annually, the Board engages

with shareholders to hear their perspectives and feedback. The Board also prioritizes these matters at each meeting through

set agenda items. Shareholders have endorsed this oversight structure and other governance enhancements.

The following chart details the primary oversight responsibilities held by each of Halliburton’s Board Committees:

Board of Directors — q	q	q	q
Nominating and Corporate Governance Committee	Audit Committee	Health, Safety and Environment Committee	Compensation Committee
• Overall sustainability • Corporate Governance Guidelines • Director self-evaluation process and performance reviews • Board refreshment • Board’s mix of skills, characteristics, experience, and expertise • Director compensation • Management succession planning • Political and lobbying spending	• Principal independent public accountants • Internal Assurance Services and the Ethics and Compliance group • Financial statements and accounting systems and controls • Enterprise risk, including information security, cybersecurity*, and artificial intelligence • Control structure for externally reported non- financial metrics	• HSE matters and sustainability • HSE risk-management processes • HSE performance • Environmental impact, including climate matters	• Overall executive compensation program • Effectiveness of compensation program to attract, retain, and motivate Section 16 officers • Pay and incentive plans metrics, including Non- Financial Strategic Metrics

*** The Board of Directors receives quarterly cybersecurity updates.

HALLIBURTON 2026 Proxy Statement 9

The Board believes that it has a strong governance structure in place to ensure independent oversight on behalf of all

shareholders. All standing Committees of the Board are comprised solely of independent Directors. Below is a discussion of

some of these areas of oversight.

Oversight of Strategy

The Board and the Board Committees oversee fundamental elements of Halliburton’s strategic plan, and company

management is charged with executing the business strategy. Throughout the year, the Board provides guidance to the

Halliburton management team in connection with this oversight function. Various elements of strategy are discussed at every

Board meeting, as well as many meetings of the Board’s Committees, at which updates on progress and execution are

delivered to the Board. The Board also periodically requests additional reports or reading materials to inform their oversight

on key and emerging aspects of our strategy. In addition, the Board dedicates at least one multi -hour session with senior

leadership each year to focus on strategic planning and related performance objectives.

Further, the Board participates in an international trip every two years and a local trip in the intervening years to review the

specific strategy and risks of those particular locations. In February 2025 , the Board traveled to t he M iddle East and Saudi

Arabia , to participate in briefings, tours, and demonstrations by local Halliburton leaders showcasing work and technologies

developed and used at the Halliburton Technology Center in Saudi Arabia. The Board continued its Saudi Arabia operations

review with meetings and tours of customer facilities and operations.

Enterprise Risk Management

Our Enterprise Risk Management (ERM) program identifies and analyzes enterprise-level risks and their potential impact on

our business. The objectives of our ERM program are to:

• increase the probability of achieving higher returns on capital and reducing cash flow volatility by identifying:

• current and developing risks; and

• significant controls and potential gaps related to identified risks;

• ensure that our key risks are being effectively managed; and

• ensure that our compensation policies incentivize management actions that both drive our strategy and manage risks

prudently.

Our internal processes to identify and manage risks include our Code of Business Conduct; extensive policies and business

practices; financial controls; internal assurance audits of our internal controls and health, safety, environment, and

sustainability; the activities of the Ethics and Compliance group of the Law Department; and our ERM program.

The Audit Committee receives an annual ERM report on risk assessment and risk management in which risks are identified

and assigned a significance rating based on potential consequences of the risk, the likelihood of occurrence, and mitigation

preparedness.

Our Chief Executive Officer, who is primarily responsible for managing our day-to-day business, is ultimately responsible to

the Board for all risk categories. Our executive officers have responsibility for the various risk categories. The Board has

delegated to its Committees the responsibility to monitor certain risks and receive regular updates on those risks.

Sustainability

The risks and opportunities presented by sustainability-related matters are particularly broad-ranging and interrelated and –

as reflected in the chart above – require coordinated oversight responsibilities among the Board and its Committees. The

Board oversees Halliburton’s performance and management across key sustainability-related matters, and the Board’s

standing Committees provide closer oversight and guidance on different aspects of sustainability issues. For example, the

Nominating and Corporate Governance Committee assesses and advises on risks that may arise in connection with

Halliburton’s overall sustainability strategy and risks, as well as individual topics such as Halliburton’s political activities,

while other Committees assess and advise on other individual sustainability-related risks and opportunities (such as the

Audit Committee’s oversight of enterprise risk, including information security, cybersecurity, and artificial intelligence, and the

Health, Safety and Environment Committee’s oversight of environmental impact (including climate matters )). The full Board

receives regular reporting from each Committee on such matters and retains ultimate oversight of all sustainability-related

matters relevant to Halliburton.

The following subsections outline the Board’s approach to overseeing three high-priority sustainability topics, corporate

political spending, cybersecurity, and artificial intelligence.

10 HALLIBURTON 2026 Proxy Statement www.halliburton.com

Political and Lobbying Spending

The Nominating and Corporate Governance Committee is responsible for oversight, review, and approval of political

engagements such as Halliburton’s lobbying activities, payments to trade associations, and political expenditures, as

provided by the Halliburton Policies for Political Engagement , which also provides a comprehensive overview of the political

activity we engaged in this year. The report is available on our website at www.halliburton.com .

Notable highlights from this report include:

• Zero corporate contributions made directly to political parties or candidates.

• Zero corporate contributions used to support ballot measures.

• Prohibitions against using corporate funds to contribute to 527 and 501(c)(4) organizations.

• Board oversight of the Company’s strategy for political engagement, including oversight of political spending and lobbying.

In 2025 , Halliburton scored a 91 on the CPA-Zicklin Index with a raw score of 64 points. A score of 90 or above indicates

robust disclosure and oversight and classifies a company as a Trendsetter, a status Halliburton first obtained in 2022 and

has maintained since then. We are one of two oilfield servic es company currently classified as a CPA-Zicklin Index

Trendsetter.

Cybersecurity

Global attacks on corporate Information Technology and Operational Technology are increasingly frequent and

sophisticated. Halliburton takes every threat to cybersecurity seriously. We invest significant resources in protecting

Company systems and data, and do so in alignment with industry standards, including the National Institute of Standards

and Technology (NIST) Cyber Security Framework, NIST 800-53, NIST 800-82, and International Electrotechnical

Commission 62443.

Halliburton’s Board of Directors receives an update on cybersecurity during each of its quarterly meetings. This update

includes data on cybersecurity metrics, information on internal and third-party cybersecurity incidents, and general

discussion of cybersecurity risks. In addition, the Audit Committee receives a detailed update annually which includes in-

depth updates on Halliburton’s cybersecurity program and strategy, including cybersecurity risks.

In the event of a cybersecurity incident, our Board and management team maintain a cyber risk management program

designed to identify, assess, manage, mitigate, and respond to cybersecurity threats. In addition, we have an Incident

Response Plan that defines procedures for assessing, identifying, and managing a cybersecurity incident. We have

experienced cybersecurity incidents and attempted breaches in the past, one of which resulted in an unauthorized third party

gaining access to certain of our systems and exfiltrating information from those systems, which we determined was a

material cybersecurity incident as previously disclosed in a Form 8-K we filed with the SEC on September 3, 2024 . The

Board and the Audit Committee provided oversight throughout the incident and in post-incident evaluation of the Company

response.

Artificial Intelligence

I n 2025, Halliburton established an Artificial Intelligence (AI) Governance and Use Committee (AI Committee), a cross

functional committee of senior leadership, to provide regular reports to the Audit Committee over AI related risks and

strategy. During a regularly scheduled meeting in 2025, the Audit Committee reviewed the AI Committee charter and related

company policy. The Audit Committee oversees the strategy of the AI Committee’s purpose to govern artificial intelligence

controls and Halliburton’s balance of AI opportunity, benefit and risk.

HALLIBURTON 2026 Proxy Statement 13

Evaluation of Board and Director Performance

The Board believes that a rigorous evaluation process is an essential component of strong corporate governance practices.

The Nominating and Corporate Governance Committee annually conducts a four-part evaluation process to evaluate Board

effectiveness and aid in succession planning.

PROCESS REVIEW	The Nominating and Corporate Governance Committee reviews and approves the process to evaluate the performance of the Board, its four standing Committees (Audit; Compensation; Health, Safety and Environment; and Nominating and Corporate Governance), and each individual Director. The Committee also approves a Director qualifications and experience survey. Questionnaires and the survey are distributed through a web-based platform. This process encourages candid responses from our Directors and promotes productive discussions.
EVALUATION	Each Director completes written questionnaires designed to gather suggestions to improve Board, Committee, and Director performance and effectiveness and to identify opportunities for change. The questionnaires solicit feedback on a range of issues, including:
	• Board operations • Succession planning • Committee composition, processes, and responsibilities • Information sharing with and from management • Overall Board dynamics	• Director preparation, participation, and contribution • Alignment of skills and characteristics to business needs and strategy • Leadership • Agenda topics
	The qualifications and experience survey identifies individual skills and expertise of each non-management Director.
ANALYSIS	The Lead Independent Director reviews the completed questionnaires and provides a summary to the Board. The Board then updates its qualifications and experience matrix based on the survey responses and feedback, with a focus on optimizing the range and depth of perspectives and experiences necessary to oversee the relevant opportunities, strategies, and risks of the Company. Through this process the Board identifies the skills and expertise desirable for future Director candidates.
ACTIONS TAKEN	The Nominating and Corporate Governance Chair reports to the Board on the results of the entire process. If warranted, the Chair of the Nominating and Corporate Governance Committee or the Lead Independent Director engage in discussions with individual Board members about their performance. This year, the Board held a discussion of the Board’s processes and the evaluation results. The Directors concluded that the Board and its Committees are functioning well.

HALLIBURTON 2026 Proxy Statement 15

Board Refreshment

The Board of Directors is responsible for filling Board vacancies when they occur, and for making sure regular Board

refreshment occurs. The Company’s Corporate Governance Guidelines stipulate that each non-management Director shall

retire from the Board immediately prior to the annual shareholder meeting that follows his or her 75 th birthday.

The Board has delegated to the Nominating and Corporate Governance Committee the duty to select and recommend new

candidates for approval. When called upon to fill a vacancy, this Committee considers all recommended candidates, and

may retain an independent executive search firm to assist with candidate selection and review.

The Nominating and Corporate Governance Committee conducts an annual review of the overall composition of the Board

to determine whether the current non-management Directors collectively represent an appropriate mix of experience,

backgrounds, and expertise. Determination of expertise includes consideration of the following, among other factors: public

company leadership, including C-suite experience; oil and natural gas experience, manufacturing, engineering, or

technology experience; and experience relating to health, safety, the environment, and sustainability. In addition, the

Nominating and Corporate Governance Committee periodically reviews a running list of potential director candidates at the

HALLIBURTON 2026 Proxy Statement 17

The Nominating and Corporate Governance Committee will consider candidates for Board membership recommended by

Board members, our management, and shareholders. The Committee may also retain an independent executive search firm

to identify candidates for consideration and to gather additional information about the candidate’s background, experience,

and reputation. A shareholder who wishes to recommend a candidate should notify our Corporate Secretary.

In anticipation of upcoming mandatory Director age retirements, our Board refreshment journey includes the enhancement

of our Board with the addition of six D ire ctors since 2022, each o f whom provide a variety of experiences and expertise to

the Board, and the refreshment and rotation of 3 of our 4 committee chairs.

With respect to Directors that have joined the Board since our most recent annual meeting, Mr. Leach joined the Board in

December 2025. Mr. Leach is a widely respected leader in the oil and gas business, bringing decades and deep expertise in

upstream operations, strategic planning, and corporate governance. Mr. Slocum joined the Board in January 2026, as a

management director, concurrent with his appointment as Executive Vice President and Chief Operating Officer, bringing

global operations experience and proven leadership to help Halliburton maximize asset value for its customers.

With several of our Directors reaching mandatory retirement age, the Board continually evaluates whether additional

Directors would enhance the Board’s oversight, experience, breadth, and other attributes. Further, the addition of new

Directors, prior to Director retirements, presents an opportunity for those Directors to learn key positions before the retiring

Director’s departure. Specifically, Mr . Cummings assumed the role of Audit Committee chair in February 2025 and Ms.

Weiss assumed the role of Health, Safety, and Environment chair in May 2025, in anticipation of the approaching mandatory

retirements of Mr. Bennett and Mr. Albrecht.

Shareholder Engagement

Halliburton’s Board values continuous improvement. We prioritize regular engagement with our shareholders through

consistent, open dialogue that helps us gather valuable feedback and ensures we are aware of investor viewpoints.

During the fall of 2025 , we participated in off-season investor meetings to better understand our shareholder priorities and

concerns prior to the proxy voting season. We offered to engage with our largest shareholders, as well as several others

who had contacted Halliburton. We offered engagement to and communicated with shareholders representing approximately

61% of our shares as well as the two largest shareholder proxy advisors , Institutional Shareholder Services (ISS) and Glass

Lewis. As a result of this outreach, we hosted video-conferences with ten shareholders who represented approximately 35%

of our shares and proxy advisors ISS and Glass Lewis. These meetings included conversations with Halliburton senior

management.

We provided our shareholder presentation to all of our largest shareholders and others who contacted Halliburton, even if

they were unable to participate in a video call. Our 2025 updates to these materials highlighted the latest information about

our business; our Board oversight and engagement; our executive compensation program; our people, health, safety, and

the environment; and our approach to sustainable energy solutions . We also offered to follow up to discuss any questions or

concerns. Our aim is to provide all shareholders the opportunity to communicate their expectations and stay abreast of our

activities, regardless of whether they are able to attend a formal meeting.

In addition to providing an off-season investor engagement program, we solicited additional shareholder feedback with our

annual and quarterly reporting, earnings conference calls, and investor meetings. We also conducted outreach to investment

research analysts and other parties who are not shareholders, but who have interest in and offer feedback about

Halliburton’s activities. As part of these campaigns, Halliburton’s senior management and Investor Relations team hosted

regular meetings and conference calls. In 2025 , we participated in 14 sell-side conferences, one non-deal roadshow, and

302 investor meetings .

Our senior management presented shareholder feedback to the Board of Directors for discussion and consideration as part

of its oversight responsibility.

Communication to the Board

and others to communicate with the Audit Committee and the Board. The process has been approved by both the Audit

Committee and the Board and meets the requirements of the NYSE and SEC. The methods of communication with the

Directors’ Compensation

Directors’ Fees

All non-management Directors receive an annual retainer of $130,000, which has not increased since 2022. The Lead

Independent Director receives an additional annual retainer of $40,000, and the chair of each Committee receives an

additional annual retainer for serving as chair as follows: Audit - $25,000; Compensation - $20,000; Health, Safety and

Environment - $20,000; and Nominating and Corporate Governance - $20,000. Non-management Directors are permitted to

defer all or part of their fees under the Directors’ Deferred Compensation Plan.

Directors’ Equity Awards

All non-management Directors receive an annual equity award with a value of approximately $200,000, increased in 2025

from $185,000, consisting of restricted stock units (RSUs), each of which represents the right to receive a share of common

stock at a future date. These annual awards are made in December. The actual number of RSUs is determined by dividing

$200,000 by the average of the closing price of our common stock on the NYSE on each business day during the month of

November. The value of the award on the date of the award may be more or less than $200,000 based on the methodology

described above for determining the number of RSUs to be awarded. Non-management Directors are permitted to defer all

of their RSUs under the Directors’ Deferred Compensation Plan.

Additionally, when a non-management Director first joins the Board, he or she receives an equity award shortly thereafter of

RSUs equal to a prorated value of the annual equity award of $200,000. The factor used to determine the prorated award is

the number of whole months of service from the beginning of the month in which Board service begins to the following first of

December divided by 12. The number of RSUs awarded is determined by dividing the prorated award amount by the

average of the closing price of our common stock on the NYSE on each business day during the full calendar month

immediately preceding the date the Director joined the Board .

Directors may not sell, assign, otherwise transfer, or encumber restricted shares (which were previously granted to non-

management Directors) or RSUs until the restrictions are removed. Restrictions on RSUs lapse entirely on the first

anniversary of the grant date with the applicable underlying shares of common stock distributed to the non-management

Director unless the Director elected to defer receipt of the shares under the Directors’ Deferred Compensation Plan. If a non-

management Director has a separation of service from the Board before completing the specified number of service years

from the applicable award date, any unvested RSUs would be forfeited, unless the Board determines to accelerate vesting.

Restrictions on restricted shares and RSUs lapse following termination of Board service only under specified circumstances,

which include death or disability, retirement under the Director mandatory retirement policy, or early retirement after at least

four years of service.

During the restriction period, Directors have the right to (i) vote restricted shares, but not shares underlying RSUs, and (ii)

receive dividends or dividend equivalents in cash on restricted shares and RSUs that have not been deferred. RSUs that

have been deferred receive dividend equivalents under the Directors’ Deferred Compensation Plan.

Directors’ Deferred Compensation Plan

The Directors’ Deferred Compensation Plan is a nonqualified deferred compensation plan and participation is completely

voluntary. Under the plan, non-management Directors are permitted to defer all or part of their retainer fees and all of the

shares of common stock underlying their RSUs when they vest. If a non-management Director elects to defer retainer fees

under the plan, then the Director may elect to have his or her deferred fees accumulate under an interest-bearing account or

translate on a quarterly basis into Halliburton common stock equivalent units (SEUs) under a stock equivalents account. If a

non-management Director elects to defer receipt of the shares of common stock underlying his or her RSUs when they vest,

then those shares are retained as deferred RSUs under the plan. The interest-bearing account is credited daily with interest

at the prime rate of Citibank, N.A. The SEUs and deferred RSUs are credited quarterly with dividend equivalents based on

the same dividend rate as Halliburton common stock, and those amounts are translated into additional SEUs or RSUs,

respectively.

34 HALLIBURTON 2026 Proxy Statement www.halliburton.com

After a Director’s retirement, distributions under the plan are made to the Director in a single distribution or in annual

installments over a five- or ten-year period as elected by the Director. Distributions under the interest-bearing account are

made in cash, while distributi ons of SEUs under the stock equivalents account and deferred RSUs are made in shares of

Halliburton common stock. Messrs. Al Khayyal, Bennett, Patel, and Smith have deferred retainer fees under the plan. Dr.

Banks, Ms. Weiss and Messrs. Al Khayyal, Albrecht, Bennett, Cummings, Patel, and Smith have deferred RSUs under the

plan.

Directors’ Stock Ownership Requirements

We have stock ownership requirements for all non-management Directors to further align their interests with our

shareholders. All non-management Directors are required to own Halliburton common stock at least equal to the greater of

(i) the annual base retainer in effect on the date the non-management Director is first elected to the Board multiplied by five

or (ii) $500,000. The Nominating and Corporate Governance Committee reviews the holdings of all non-management

Directors, which include restricted shares, other Halliburton common stock, SEUs, and RSUs owned by the Director, at each

May meeting. Each non-management Director has five years to meet the requirements, measured from the date he or she is

first elected to the Board. Each non-management Director currently meets the stock ownership requirements or is on track to

do so within the requisite five-year period.

Director Clawback Policy

We have adopted a supplemental recoupment policy under which we may seek, in appropriate cases, to recoup incentive-

based compensation, including both time- and performance-vesting awards paid to, awarded to, or credited for the benefit of

a Director, if and to the extent that it is determined that, in connection with the performance of that Director’s duties, he or

she breached his or her fiduciary duty through a knowing or reckless material violation of law; breached the Company’s

Code of Business Conduct in a matter that results in, or could reasonably expect to result in, material, reputational, or

financial harm to the Company; or recklessly disregarded his or her duty to exercise reasonable oversight. We may also

recoup incentive-based compensation if the Director is named as a defendant for such actions above, and we either

determine that the action is not indemnifiable or the Director does not prevail at trial.

The disinterested members of the Board and the disinterested members of the Compensation Committee and the

Nominating and Corporate Governance Committee may be involved in reviewing, considering, and making determinations

regarding the Director’s alleged conduct, whether recoupment is appropriate or required, and the type and amount of

incentive compensation to be recouped from the Director.

There was no recoupment under the supplemental policy in 2025 .

Value and Nonqualified Deferred Compensation Earnings column are attributable to the above-market earnings for cash

deferrals to our nonqualified deferred compensation plan. The methodology for determining what constitutes above-market

earnings is the difference between the interest rate as stated in the plan document and the Internal Revenue Service Annual

Long-Term 120% AFR rate as of December 31, 2025 . The 120% Annual AFR rate used for determining above-market

earnings in 2025 was 5.47%. The average Director earnings for the balances associated with the Directors’ Deferred

Compensation Plan were 7.83% for 2025 . The average above-market earnings associated with this plan equaled 2.36%

(7.83% minus 5.47%) for 2025 .

A Note About Charitab le Giving and Matching . H alliburton believes charitable giving and charitable matching programs

benefit the communities in which we live and work and are the right thing to do. These charitable gifts include a corporate

match that all employees and Directors may access to direct giving to accredited colleges and universities, qualified medical

institutions, and K-12 educational institutions. The employee and director gift amount subject to corporate match is capped

at $20,000 for employees and $50,000 for directors. The K-12 educational institution gift amount subject to corporate match

is capped at $500 for matching purposes or up to $1,125 in corporate match. By matching charitable gifts to colleges and

universities and K-12 educational institutions, we invest in the next generation and help build a sustainable pipeline of talent.

During shareholder engagement, our shareholders have provided feedback to us that investing in the future through giving

to colleges and universities is one positive way to attract future employees. By matching charitable gifts to qualified medical

institutions, we invest in the foundational medical support that allow the places where we live and work to thrive. For

Directors and officers who participate, the “ All Other Compensation” column will include a calculation of the charitable

match. Here are a few examples of matches: Directors make charitable contributions to support colleges and universities as

we collectively work to improve recruiting and STEM programs, and also to Connecticut Children’s Foundation whose

mission is to improve the physical, social, and emotional health of children. For Directors, the Halliburton Foundation

matches personal contributions up to 2.25 times the amount contributed by the Director, with the matched funds paid directly

to the college, university, or hospital or K-12 educational institution, not the Directors. Our Directors derive no personal

benefit from these contributions. Neither the Halliburton Foundation nor we have made a charitable contribution, within the

preceding three years, to any charitable organization in which a Director serves as an executive officer that exceeds in any

single year the greater of $1 million or 2% of such charitable organization’s consolidated gross revenues. Finally, if they

choose to participate, the Halliburton Political Action Committee allows Directors to participate in HALPAC, and the

Company provides a dollar-for-dollar match on contributions over $100 annually, up to a $5,000 limit match to a 501(c)(3)

nonprofit organization of the contributor’s choice.

Proposal No. 2 Ratification of Selection

of Principal Independent Public

Accountants

The Audit Committee is responsible for the appointment, compensation, retention, oversight of the work, and evaluation of

the principal independent public accountants retained to audit our financial statements. The Audit Committee and Board

have approved the selection of KPMG LLP as our principal independent public accountants to examine our financial

statements and books and records for the year ending December 31, 2026 , and a resolution will be presented at the Annual

Meeting to ratify this selection. The Audit Committee and Board believe that the continued retention of KPMG to serve as our

principal independent public accountants for the year ending December 31, 2026 , is in the best interests of Halliburton and

our shareholders. Representatives of KPMG are expected to be present at the Annual Meeting and be available to respond

to appropriate questions from shareholders.

KPMG began serving as our principal independent public accountants for the year ended December 31, 2002. The Audit

Committee routinely reviews the performance and retention of our independent public accountants, including an evaluation

of service quality, the nature and extent of non-audit services, and other factors required to be considered when assessing

independence from Halliburton and its management. The Audit Committee also periodically considers whether there should

be a rotation of the principal independent public accountants and is involved in the selection of the principal independent

public accountants’ lead engagement partner and the mandated rotation process of such partner.

Vote Required

The affirmative vote of the majority of the votes cast by holders of shares of our common stock present in person or

represented by proxy at the meeting and entitled to vote on the subject matter is needed to approve the proposal.

Although the ratification of the appointment of our principal independent public accountants is not required to be submitted to

a vote of shareholders, we value the opinions of our shareholders and believe that shareholder ratification of such

appointment is a good corporate governance practice. If the shareholders do not ratify the appointment of KPMG, the Board

will reconsider the appointment of independent public accountants.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR RATIFICATION OF THE APPOINTMENT OF KPMG LLP AS PRINCIPAL INDEPENDENT PUBLIC ACCOUNTANTS TO EXAMINE OUR FINANCIAL STATEMENTS AND BOOKS AND RECORDS FOR THE YEAR ENDING DECEMBER 31, 2026 .

Audit Committee Report

We operate under a written charter, a copy of which is available on Halliburton’s website at www.halliburton.com . As

required by the charter, we review and reassess the charter annually and recommend any changes to the Board for

approval. We are also mindful of the observations provided in the Securities and Exchange Commission’s Statement on

Role of Audit Committees in Financial Reporting and Key Reminders Regarding Oversight Responsibilities.

Halliburton’s management is responsible for preparing Halliburton’s financial statements, and the principal independent

public accountants are responsible for auditing those financial statements. The Audit Committee’s role is to provide oversight

of management in carrying out management’s responsibility and to appoint, compensate, retain, oversee the work of, and

evaluate the principal independent public accountants. The Audit Committee is not providing any expert or special

assurance as to Halliburton’s financial statements or any professional certification as to the principal independent public

accountants’ work.

In fulfilling our oversight role for the year ended December 31, 2025 , we:

• reviewed and discussed Halliburton’s audited financial statements with management;

• discussed with KPMG LLP, Halliburton’s principal independent public accountants, the matters required by Auditing

Standard 1301 relating to the conduct of the audit;

• received from KPMG the written disclosures and the letter required by the Public Company Accounting Oversight Board

regarding KPMG’s independence;

• evaluated KPMG’s service quality; and

• discussed with KPMG its independence and reviewed other matters required to be considered under Securities and

Exchange Commission rules regarding KPMG’s independence.

Based on the foregoing, we recommended to the Board that the audited financial statements be included in Halliburton’s

Annual Report on Form 10-K for the fiscal year ended December 31, 2025 , for filing with the Securities and Exchange

Commission.

Fees Paid to KPMG LLP

During 2024 and 2025 , we incurred the following fees for services performed by KPMG LLP .

	2024	2025
	(In millions)	(In millions)
Audit fees	$ 12.9	$ 13.1
Audit-related fees	0.5	0.5
Tax fees	0.6	0.9
All other fees	0.7	0.8
TOTAL	$ 14.7	$ 15.3

Audit Fees

Audit fees represent the aggregate fees for professional services rendered by KPMG for the integrated audit of our annual

financial statements for the fiscal years ended December 31, 2024 , and December 31, 2025 . Audit fees also include the

audits of many of our subsidiaries to comply with statutory requirements in foreign countries and reviews of our financial

statements included in the Forms 10-Q we filed during fiscal years 2024 and 2025 .

Audit-Related Fees

Audit-related fees were incurred for assurance and related services that are traditionally performed by the independent

public accountants. These services primarily include attestation engagements required by contractual or regulatory

provisions.

Tax Fees

The aggregate fees for tax services primarily consisted of international tax compliance, international tax advisory, and tax

return services related to our expatriate employees. In 2024 , tax compliance and advisory fees totaled $0.3 million and

expatriate fees totaled $0.3 million, and in 2025 tax compliance and advisory fees totaled $0.9 million and expatriate tax fees

were zero .

All Other Fees

All other fees are comprised of professional services rendered by KPMG related to nonrecurring miscellaneous services.

Fee Approval Policies and Procedures

The Audit Committee has established a written policy that requires the approval by the Audit Committee of all services

provided by KPMG as the principal independent public accountants that examine our financial statements and books and

records and of all audit services provided by other independent public accountants. Prior to engaging KPMG for the annual

audit, the Audit Committee reviews a Principal Independent Public Accountants Auditor Services Plan. KPMG then performs

services throughout the year as approved by the Committee. KPMG reviews with the Committee, at least quarterly, a

projection of KPMG’s fees for the year. Periodically, the Audit Committee approves revisions to the plan if the Committee

determines changes are warranted. Our Audit Committee also considered whether KPMG’s provision of tax services as

reported above were compatible with maintaining KPMG’s independence as our principal independent public accountants.

All of the fees described above for services provided by KPMG were approved in accordance with the policy.

Proposal No. 3 Advisory Approval of

Executive Compensation

Pursuant to Section 14A of the Securities Exchange Act of 1934, our shareholders have the opportunity to vote to approve,

on an advisory basis, the compensation of our Named Executive Officers (NEOs) as disclosed in this proxy statement. As

reaffirmed by our shareholders at the 2023 Annual Meet ing of Shareholders , consistent with our Board’s recommendation,

we submit this proposal for a non-binding vote on an annual basis.

As described in detail under Compensation Discussion and Analysis, our executive compensation program is designed to

attract, motivate, and retain our NEOs, who are critical to our success. Under the program, our NEOs are rewarded for the

achievement of specific annual, long-term, and strategic goals, corporate goals, and the realization of increased shareholder

returns. Please read Compensation Discussion and Analysis for additional details about our executive compensation

program, including information about the fiscal year 2025 compensation of our NEOs and our Board’s ongoing commitment

to ensure that our program aligns with our long-term strategy and shareholder value creation.

The Compensation Committee reviews the compensation program for our NEOs to ensure the program achieves the

desired goals of aligning our executive compensation structure with our shareholders’ interests and current market practices.

We believe our executive compensation program achieves the following objectives identified under Compensation

Discussion and Analysis:

• Provide a clear and direct relationship between executive pay and our performance on both a short-term and long-term

basis;

• Target market competitive pay levels with a comparator peer group;

• Emphasize operating performance drivers;

• Link executive pay to measures that drive shareholder returns;

• Support our business strategies; and

• Maximize the return on our human resource investment.

We ask that our shareholders indicate their support for our compensation program as described in this proxy statement and

vote “FOR” the following resolution at the Annual Meeting: “RESOLVED, that the compensation paid to Halliburton’s Named

Executive Officers, as disclosed in this proxy statement pursuant to Item 402 of Regulation S-K, including the Compensation

Discussion and Analysis, compensation tables, and narrative discussion, is hereby approved.”

Vote Required

The affirmative vote of the majority of the votes cast by holders of shares of our common stock present in person or

represented by proxy at the meeting and entitled to vote on the subject matter is needed to approve the proposal.

Our Board and our Compensation Committee value the opinions of our shareholders. The say-on-pay vote is advisory and,

therefore, not binding on us, our Board, or our Compensation Committee. However, the Compensation Committee considers

shareholder feedback in its ongoing review of our executive compensation program.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.

Compensation Discussion and Analysis

To Our Valued Shareholders:

“ Our executive compensation program is built on best-practice design and continues

to deliver on its core purpose—driving superior returns and reinforcing Halliburton’s

strong culture of execution. Its strength reflects the rigor of our performance metrics,

the consistency of our governance, and the ongoing engagement with shareholders

that reinforces alignment and accountability. ”

Murry S. Gerber

Chair of the Compensation Committee

March 31, 2026

The approximately 94 % say-on-pay support at the 2025 Annual Meeting reaffirms confidence in our approach, validating a

framework that balances performance and investor expectations with the realities of a cyclical energy sector and positions

leadership to navigate evolving market conditions.

In 2025 , Halliburton delivered strong results, returning $ 1.6 billion to shareholders through dividends and share repurchases

while generating $2.9 billion of operating cash flow, resulting in $1.9 billion in free cash flow . Despite macroeconomic

headwinds, our senior leadership team navigated the environment with strategic precision, reducing gross debt by $ 382

million and further strengthening our balance sheet. While revenue declined year over year, our sustained Return on Capital

Employed (ROCE) performance over multi-year periods highlights the senior leadership team’s ability to drive financial

discipline, operational excellence, and long-term value creation in a challenging market. Our executive compensation

program is designed to reinforce this disciplined approach, ensuring senior leadership remains sharply focused on delivering

sustainable performance and long-term shareholder value.

This year’s Compensation Discussion and Analysis (CD&A) summarizes the pay decisions made by the Compensation

Committee for Named Executive Officers (NEOs) for 2025 and reviews the ongoing shareholder engagement efforts that

have helped shape our executive compensation program’s current structure and governance foundation.

As always, we appreciate the care you take in reading this year’s CD&A, and we are confident it demonstrates our

commitment to continually strengthening our pay program structure and alignment with our shareholders’ interests.

Sincerely,

Shareholder Outreach and Board Activity

Halliburton prioritizes continuing engagement with its shareholders. Our ongoing and earnest engagement with long-term

investors ensures that the Board and management understand investors’ views and provides our Compensation Committee

with valuable feedback.

During the fall of 2025, we participated in off-season investor meetings to better understand shareholder priorities and

concerns prior to the proxy voting season. We offered to engage with our largest shareholders, as well as several others

who had contacted Halliburton. We offered engagement to and communicated with shareholders representing approximately

61% of our shares as well as the two largest shareholder proxy advisors , Institutional Shareholder Services (ISS) and Glass

Lewis. As a result of this outreach, we hosted video-conferences with ten shareholders who represented approximately 35%

of our shares and proxy advisors ISS and Glass Lewis. These meetings included conversations with Halliburton senior

management. These efforts were conducted in addition to the 14 sell-side conferences, one non-deal roadshow, and 302

investor meetings , that are all part of our regular shareholder outreach cadence.

Management reviewed the previously disclosed updates to the Performance Peer Group with shareholders . Those

discussions included a variety of topics including the relevance of the Philadelphia Oil Service Index (OSX) and

Performance Peer Group used for measuring relative performance to determine payouts under our Performance Unit

Program (PUP). The discussion noted that the OSX includes a much broader collection of energy services, and not simply

oilfield services, and includes services such as liquified natural gas (LNG) and others while at the same time excluding

oilfield services companies such as Baker Hughes Company and Liberty Energy Inc. The discussion also covered the

importance of ensuring that Halliburton’s Performance Peer Group remains relevant and robust in a rapidly evolving

business landscape, including as a service provider to the exploration and production industry, which is rapidly

consolidating. Halliburton heard from shareholders general support for the new Performance Peer group and understanding

about the OSX composition. The discussions with ISS and Glass Lewis included questions and answers about this

shareholder feedback and general support for the new Performance Peer Group.

During these discussions in 2025, investors expressed high satisfaction with how Halliburton’s executive compensation

program is structured today. At our 2025 Annual Meeting, approximately 94 % of the votes cast for say-on-pay supported our

executive compensation decisions . Shareholders made it clear that they are pleased with our ongoing responsiveness to

their feedback, our overall compensation design, including the specific, measurable metrics in our Annual Performance Plan,

and the use of relative Return on Capital Employed (ROCE) and Total Shareholder Return (TSR) in the PUP. Other than

updating the Performance Peer Group used in the Performance Unit Program, we did not make any material changes to our

program for 2025. The details of this update are discussed in the 2025 Performance Peer Group section of this CD&A.

Straight from the Boardroom:

Talking with Murry S. Gerber

Robust discussions with investors have led to meaningful and well-received changes to our executive compensation program. Below are the answers to recent representative shareholder questions from Murry S. Gerber, Chair of our Compensation Committee.

Q. What was the Compensation Committee ’ s reaction to the 2025 Annual Meeting, when over 94% of shareholders

supported the 2025 say-on-pay proposal?

A We were pleased to once again receive support from more than 90% of our shareholders. We believe strong support for

the say-on-pay proposal in recent years has been due in large part to the Committee ’ s years of listening to

shareholders, thoughtfully integrating feedback, and aligning our executive compensation program with investor

expectations–without compromising our commitment to driving superior returns and balancing compensation against a

competitive market for talent. Because this is a highly cyclical business, the Committee must maintain vigilance and

awareness of competition for talent and associated compensation for it.

Regular engagement ensures we stay ahead of and understand any emerging investor concerns. We were also

pleased that, during our engagement with shareholders during the fall of 2025, our largest shareholders made it clear

that they are pleased with our overall compensation design.

Q Why were the 2025 financial performance targets under the Annual Performance Pay Plan set below 2024

actual results?

A Fundamentally and first , this is without question a highly cyclical business that operates against a geopolitical backdrop

that substantially influences the macro supply and demand balance for oil and gas.

The Annual Performance Pay Plan includes two key financial measures, Net Operating Profit After Taxes (NOPAT) and

Asset Turns, which together evaluate profitability, capital efficiency, and free cash flow generation. These metrics are

fundamental to how Halliburton manages its business and reflect shareholder expectations for disciplined execution and

sustained returns across market cycles.

When establishing the 2025 financial performance targets at the beginning of the year, the Compensation Committee

reviewed the Company ’ s annual operating plan, market forecasts, and broader industry trends. Following two years of

strong recovery, the Compensation Committee expected 2025 to reflect a more normalized operating environment.

Market indicators pointed to steady activity levels, continued capital discipline among customers, and pricing stability

rather than further expansion. These conditions were expected to moderate revenue growth and margin performance,

directly affecting the NOPAT and Asset Turns measures that drive plan outcomes.

In this context, the Compensation Committee determined that it was appropriate to set 2025 financial performance

targets below 2024 actual results to ensure the targets represented realistic stretch performance—levels that remain

challenging and demand continued focus on cost management, operational efficiency, and capital returns. The

Compensation Committee cannot and does not assume performance will rise mechanically each year; rather, it

calibrates targets based on the conditions expected for the plan year, ensuring that they remain rigorous and aligned

with the realities of the business and the broader industry. This approach is a natural consequence of operating in the

oilfield services industry, and one that is tailored to our industry. In a cyclical market, the Board and Compensation

Committee evaluate a wide range of leading indicators for the forthcoming year and set financial performance targets

that they believe appropriately challenge executive performance while remaining grounded in the expected and most

realistic estimates for the operating landscape.

This approach is consistent with how the Compensation Committee has managed incentive design throughout the

cycle. In periods of expansion, financial performance targets are set to drive improvement over already strong

performance; during periods of normalization or contraction, they are established to preserve profitability, optimize asset

utilization, and reinforce capital discipline. The Compensation Committee believes in setting realistic stretch targets, as

evidenced during past industry downturns, when it established goals it believed to be achievable yet demanding, and in

several years, those targets were not met. That experience underscores the Compensation Committee ’ s commitment to

46 HALLIBURTON 2026 Proxy Statement www.halliburton.com

maintaining rigor and credibility in incentive design and ensuring that the Annual Performance Pay Plan continues to

support long-term shareholder value creation through changing market conditions.

To further illustrate that financial performance targets do not automatically increase in a cyclical business, despite the

2024-to-2025 financial targets and Halliburton’s strong relative performance versus peers, management did not earn a

NOPAT payout under the Annual Performance Pay Plan .

Q Why is Halliburton proposing to replenish shares under the Halliburton Company Stock and Incentive Plan

(SIP) and the Halliburton Employee Stock Purchase Plan (ESPP), and how do you address concerns about

dilution?

A These programs are essential to how we motivate, retain and align our people with long-term shareholder value. Equity

ownership matters in our culture—from our executive leadership team to employees across the Company. At the same

time, we are mindful of dilution and burn-rate impacts. When evaluating this proposal, we compared our projected

dilution and historical burn-rate to other leading companies in the oilfield services sector. This is important because

companies in our industry rely heavily on equity programs to attract and retain technical and operational talent, and

investors typically assess dilution relative to these industry practices. We sized our request to keep Halliburton generally

aligned with the levels we observed among peers, ensuring we remain within market norms while preserving programs

that are critical to our ability to attract, retain, and engage the workforce that drives our performance.

Q How does the Compensation Committee determine Halliburton ’ s Comparator Peer Group?

A The Compensation Committee applies a comprehensive and data-driven approach to developing Halliburton’s

Comparator Peer Group. Our objective is to create a peer set that reflects the size, scale, scope, and complexity of

Halliburton’s global operations and aligns with investor expectations for a disciplined and transparent evaluation

process. The resulting group serves as a robust foundation for assessing the competitiveness, balance, and

effectiveness of our executive compensation program.

Each year, with support from our independent compensation consultant, the Compensation Committee conducts a

detailed review of the peer group to confirm that it continues to reflect companies comparable to Halliburton in business

model, geographic reach, and operational complexity. The process begins with the existing peer group and expands to

include potential peers identified through institutional investor research, management and Board input, and analysis of

organizations that compete with Halliburton for business opportunities and leadership talent.

From this broader pool, the Compensation Committee conducts a structured, multi-factor screening process that

considers a blend of financial, operational, and qualitative criteria, including revenue, market capitalization, employee

base, industry affiliation (such as oilfield services, drilling, and related energy or industrial sectors), geographic footprint,

operating characteristics, corporate headquarters location, and stock price correlation. The Compensation Committee

also evaluates each company’s business complexity, global presence, and financial stability to ensure appropriate

comparability. To maintain balance and relevance, the Compensation Committee focuses on companies of comparable

scale and operational breadth—typically within a revenue range that aligns with Halliburton’s position in the market—

while retaining flexibility to include strategically important competitors whose size or structure differs but whose

business dynamics or talent markets are directly relevant. This was the process that we followed in updating the

Performance Peer Group used in the Performance Unit Program this past year. (See page 4 4 for additional details on

this change.)

Q. Did the Company hear anything during the fall 2025 engagement meetings that has the Committee

contemplating any changes for 2026?

A No. During the fall 2025 shareholder engagement cycle, investors expressed broad support for the structure and

operation of Halliburton’s executive compensation program. Feedback reaffirmed confidence in the Compensation

Committee’s use of returns-based metrics, particularly ROCE under the PUP, as well as the continued emphasis on

profitability, capital efficiency, and free cash flow generation under the Annual Performance Pay Plan. Investors also

noted the value of the Company’s transparent disclosure and the Compensation Committee’s disciplined approach to

target-setting across varying market conditions.

HALLIBURTON 2026 Proxy Statement 47

2025 CEO Compensation Overview

Determination of CEO Target Total Compensation

When determining target total compensation for the CEO, the Compensation Committee evaluates CEO compensation

through various lenses to ensure that it is setting competitive total target compensation opportunities and approving actual

compensation outcomes that are aligned with actual performance results and shareholder expectations.

Under our PUP, we use a mix of performance cash (50%) and performance stock (50%). This approach affects how we

report executive compensation in the Summary Compensation Table, making it impractical to directly compare our

executives’ actual reported pay with competitors who use 100% stock for long-term incentives—because under the SEC’s

reporting rules, these two methods yield different disclosures. Specifically, performance cash is reported when paid and

performance stock is reported when granted. This means that when we outperform our competitors, our reported pay can be

materially higher than theirs even if their actual pay is the same or higher. In other words, to achieve a comparator like-for-

like compensation analysis, additional analysis is required.

Total target compensation for our CEO is structured to target market competitive pay levels in base salary and short- and

long-term incentive opportunities relative to market pay levels for CEOs in our Comparator Peer Group. Total target

compensation opportunities are set by the Compensation Committee at the beginning of each performance period and are

intended to be forward looking. Because our philosophy places an emphasis on variable pay at risk, and also uses a mix of

cash and stock for performance-based long-term incentives, actual pay results may be above or below the 50 th percentile of

our Comparator Peer Group depending on performance.

The chart below compares Mr. Miller’s last five years of total target compensation as approved by the Compensation

Committee to the total target compensation of our two largest peers in the oilfield sector :

As shown above, Mr. Miller’s year-over-year increase in target total compensation reflects adjustments made in 2025 to

align his compensation with our philosophy of targeting market median pay levels for our NEOs. Specifically, adjustments

were made to the following pay elements for Mr. Miller:

• Base Salary - Increased from $1.65 million to $1.70 million in recognition of his performance and to align his total target

direct compensation with the market median of our Comparator Peer Group.

• Short Term Incentive Target - Remained unchanged at 150% of base salary. The increase in STI target compensation

noted above is a result of the increased salary for 2025.

• Long Term Incentive (LTI) Target - Increased by $928,000 to align with the market median LTI of our Comparator Peer

Group.

48 HALLIBURTON 2026 Proxy Statement www.halliburton.com

The Compensation Committee also considers the CEO’s performance and accomplishments in the areas of business

development and expansion, management succession, development and retention of management, ethical leadership, and

the achievement of financial and operational objectives. Each year, our CEO and the members of the Board agree upon a

set of objectives addressing the following areas:

• Leadership and vision;

• Integrity;

• Keeping the Board informed on matters affecting Halliburton;

• Performance of the business;

• Development and implementation of initiatives that provide long-term economic benefits;

• Accomplishment of strategic objectives; and

• Development of management.

Other NEOs’ compensation is determined similarly by evaluating each NEO’s performance and considering the market

competitive pay levels of the Comparator Peer Group for the NEO’s position. The Compensation Committee also considers

the importance of keeping our management team focused and stable, especially given that other oilfield services companies

have aggressively recruited our NEOs and other executives in the past, with more than thirty former Halliburton executives

departing to become CEOs and/or senior executives of other oilfield services companies.

2025 Performance Overview

Business Highlights

Our success throughout 2025 was a direct result of the hard work and dedication of our employees with relentless focus on

safety, operational execution, customer collaboration, and service quality performance. In 2025, Halliburton delivered solid

results through clear strategy and disciplined execution. We generated $22.2 billion in total company revenue, and we

achieved another year of strong free cash flow through cost and capital discipline. Here are the highlights for 2025 :

• Financial: Our total revenue decreased 3% in 2025 as compared to 2024. Our international revenue decreased 2% and

our North America revenue decreased 6% in 2025 compared to 2024. Overall, our Completion and Production and Drilling

and Evaluation operating segments finished the year with 17% and 15% operating margins, respectively. We generated

$2.9 billion of cash flows from operations and retired $382 million of our 3.8% notes due November 2025.

• Capital efficiency: We developed technologies and made strategic choices that kept our capital expenditures at

approximately 6% of revenue, which matched our target.

• Shareholder returns: We returned $1.6 billion of capital to shareholders through dividends and share repurchases, which

is consistent with our capital returns framework.

• Sustainability: We continued progress toward a sustainable energy future by expanding Halliburton Labs ’ 38 participant

and alumni organizations, and achieving the milestone of 50% of our North American fracturing fleet transitioned to Zeus

electric pumps .

HALLIBURTON 2026 Proxy Statement 51

Cash Flow Execution

(billions USD)

During 2025, we generated $2.926 billion of operating cash flow and had $1.254 billion of capital expenditures and $185

million of proceeds from sales of property, plant, and equipment, resulting in $1.857 billion of f ree cash flow*. This

demonstrates our ability to generate strong free cash flow for our shareholders. We returned approximately $1.6 billion of

capital to shareholders through share repurchases and dividends.

*** Free cash flow is a non-GAAP measure which is calculated as “Total cash flows provided by operating activities (operating cash flow)”

less “capital expenditures” plus “proceeds from the sale of property, plant, and equipment.” Management considers free cash flow an

important indicator of the company ’ s liquidity, as it helps both investors and management evaluate the business’s ability to generate

cash. See Appendix D for reconciliation to U.S. GAAP.

and long-term incentives as described below :

	Reward Element	Objective	Key Features	How Award Value is Determined	2025 Decisions
FIXED	Base Salary	To compensate executives based on their responsibilities, experience, and skill set.	Fixed element of compensation paid in cash.	Benchmarked against a group of comparably sized corporations and industry peers.	Base salary determinations varied by individual as noted on page 58 .
AT RISK	Short-Term (Annual) Incentive	To motivate and incentivize performance over a one-year period.	Award value and measures are reviewed annually. Targets are set at the beginning of the period.	Performance measured against: • 60% NOPAT • 20% Asset Turns • 20% Non-Financial Strategic Metrics	Award values were targeted at the market median for 2025.
	Long-Term Incentives	To motivate and incentivize sustained performance over the long-term. Aligns interests of our NEOs with long-term shareholders.	Value is delivered: • 70% performance units measured over three years (½ in stock; ½ in cash) with relative TSR modifier • 30% restricted stock	The 2025 performance units measured against ROCE performance relative to performance peers and including a relative TSR modifier. Relative ROCE performance required for a target PUP payout is set at the 55th percentile. Payouts of the primary metric (relative ROCE) are capped at target if average HAL ROCE for the applicable three-year performance period is negative. Restricted stock grants have time-based vesting and value is driven by our share price.	Award values were targeted at the market median for 2025.

HALLIBURTON 2026 Proxy Statement 55

Compensation Mix

As illustrated below, the majority of our CEO’s and NEOs’ total direct compensation opportunity is performance-based, at-

risk, and long-term. The following graphs show the mix of total target direct compensation set for our CEO and NEOs for the

2025 plan year. As part of its process, the Compensation Committee makes decisions about target long-term incentive

award opportunities for the following year during its regular December meeting.

90% At-Risk Compensation
74% Long-Term Incentives

83% At-Risk Compensation
65% Long-Term Incentives

Setting Executive Compensation

Role of the Compensation Committee

The Compensation Committee oversees the executive compensation program and has overall responsibility for making final

decisions about total compensation for all of the NEOs, except for the CEO, whose compensation is set by the entire Board

of Directors. As part of its annual process, the Compensation Committee works closely with senior management (as

appropriate) and the Compensation Committee’s independent compensation consultant. This process ensures consistency

from year to year and adherence to the responsibilities listed in the Committee’s Charter, which is available on our website.

The CEO does not provide recommendations concerning his own compensation, nor is he present when his compensation

is discussed by the Compensation Committee. The Compensation Committee, with input from its independent compensation

consultant, discusses the elements of his compensation in executive session and makes a recommendation to all non-

management Directors for discussion and final approval. At the Compensation Committee’s request, a member of

management attends the executive session to answer questions.

The CEO, with input from the Compensation Committee’s independent compensation consultant, assists the Compensation

Committee in setting compensation for the other NEOs.

56 HALLIBURTON 2026 Proxy Statement www.halliburton.com

Use of Independent Consultants and Advisors

The Compensation Committee engaged Pearl Meyer as its independent compensation consultant during 2025. Pearl Meyer

does not provide any other services to us. The primary responsibilities of the independent compensation consultant are to:

• Provide independent and objective market data;

• Conduct compensation analysis;

• Recommend potential changes to the Comparator Peer Group and Performance Peer Group;

• Recommend plan design changes;

• Advise on risks associated with compensation plans; and

• Review and advise on pay programs and pay levels.

These services are provided as requested by the Compensation Committee throughout the year. Based on their review of

our executive compensation program, Pearl Meyer concluded that our compensation plans do not appear to present any

material risks to the Company or its shareholders.

Comparator and Performance Peer Companies

The Compensation Committee uses various market data to examine and set target compensation opportunities for the

NEOs, as well as to determine actual award payouts, to ensure that it provides competitive compensation opportunities and

approves actual compensation outcomes that are aligned with shareholder expectations. In determining appropriate bases

for comparison, the Compensation Committee and its external compensation consultant have considered the fact that we

operate in an industry with very few direct peers of our size and reach. Additionally, many companies of our size and talent

composition operate in industries that lack the cyclicality of our own. As a result, the Compensation Committee has

determined that multiple peer groups should be employed, for specific purposes. We have discussed these peer groups with

our shareholders, who are aware of the peer group construction challenges we face and are supportive of the groups we

have developed. The following provides context for the different peer groups used to support the Compensation Committee’s

process:

Comparator Peer Group — used to determine market levels of total compensation for the 2025 plan year.
Performance Peer Group — used to evaluate Halliburton ’ s relative performance for both ROCE and TSR over a three-year performance period for determining PUP payouts for the 2025 PUP Cycle. (See “ 2025 Performance Peer Group ” below.)
Philadelphia Oil Service Index (OSX) — used to evaluate Halliburton ’ s relative TSR over a three-year period for determining the PUP payout for the 2023 PUP Cycle.

2025 Comparator Peer Group

The Compensation Committee regularly assesses the market competitiveness and effectiveness of the Company’s

executive compensation program using a carefully constructed Comparator Peer Group. With support from its independent

compensation consultant, the Compensation Committee conducts a comprehensive, data-driven review of the Comparator

Peer Group each year to confirm that it continues to reflect companies comparable to Halliburton in business model,

operational scale, and global complexity.

The selection process begins with the existing Comparator Peer Group and expands to include potential comparators

identified through institutional investor research, management and Board input, and independent analyses of companies that

compete with Halliburton for business opportunities and leadership talent. The Compensation Committee applies a

structured, multi-factor screening process informed by quantitative and qualitative data. Key considerations include revenue,

market capitalization, number of employees, global impact and reach, operating characteristics, and corporate headquarters

location. These factors are evaluated together to identify companies that share Halliburton’s scale, scope, and operating

profile.

Industry affiliation is also an important consideration, particularly among companies engaged in oil and natural gas

exploration, energy services, and related sectors. However, the Compensation Committee recognizes that many of

Halliburton’s direct industry peers are significantly smaller in size and scope. To ensure a meaningful comparison set, the

Compensation Committee includes strategically relevant companies outside the immediate oilfield services sector that

exhibit comparable operational characteristics, capital intensity, and geographic reach.

The resulting Comparator Peer Group provides a balanced mix of energy and diversified industrial companies that reflect

Halliburton’s global footprint and business complexity, while maintaining sufficient industry relevance for evaluation. With

support from its independent compensation consultant, the Compensation Committee reviews market data from public filings

HALLIBURTON 2026 Proxy Statement 57

and third-party compensation databases and adjusts for differences in company size, typically based on revenue, to ensure

appropriate comparability.

The 2025 Comparator Peer Group was composed of the following peer companies within the energy industry, as well as

selected companies representing general industry. The 2 025 Comparator Peer Group is unchanged from 2024. This peer

group was utilized to determine market levels of total compensation for the 2025 plan year:

3M Company	Hess Corporation
APA Corporation	Honeywell International Inc.
Baker Hughes Company	Johnson Controls International plc
Caterpillar Inc.	NOV Inc.
ConocoPhillips	Occidental Petroleum Corporation
Deere and Company	SLB N.V.
Emerson Electric Co.	Transocean Ltd.
Fluor Corporation	Weatherford International plc

Because of variances in market capitalization and revenue size among the companies comprising our Comparator Peer

Group, the market data is size adjusted by revenue as necessary so that it is comparable with our trailing 12-month revenue.

These adjusted values are used to compare our executives’ compensation to those of the Comparator Peer Group.

Total compensation for each NEO is structured to target market-competitive pay levels in base salary and short- and long-

term incentive opportunities. We also place an emphasis on variable pay at risk, which enables this compensation structure

to position actual pay above or below the 50 th percentile of our Comparator Peer Group depending on performance.

A consistent pre-tax, present value methodology is used in assessing stock-based and other long-term incentive awards.

The independent compensation consultant gathers and performs an analysis of market data for each NEO, comparing each

of their individual components of compensation and total compensation to those of the Comparator Peer Group. This

competitive analysis consists of comparing the market data of each of the pay elements and total compensation at the 25 th ,

50 th , and 75 th percentiles of the Comparator Peer Group to current compensation for each NEO.

2025 Performance Peer Group

For determining PUP award payouts, the Compensation Committee compares ROCE on a relative basis over three years to

the results of a performance peer group it selects. The Performance Peer Group used for the PUP is reviewed annually by

the Committee and is comprised of oilfield equipment and services companies and oil and gas contractors. This peer group

is used for the PUP because these companies represent the timing, cyclicality, and volatility of the oil and natural gas

industry and provide an appropriate industry group for measuring our relative performance.

The Compensation Committee, as part of its ongoing oversight, closely monitors industry trends and evaluates how changes

might affect our executive compensation program. The ongoing consolidation in the exploration and production sector has

emerged as a shared priority and a main topic of discussion for both the Compensation Committee and our shareholders.

During our 2024 shareholder outreach meetings, investors highlighted the potential impact of the ongoing consolidation on

the relevance of our Performance Peer Group used for measuring relative performance to determine payouts under our

PUP. While no formal directives were given, these discussions underscored the importance of ensuring our Performance

Peer Group remains relevant and robust in a rapidly evolving business landscape. As such, a new performance peer group

was implemented in 2025 for purposes of evaluating Halliburton ’ s relative performance for both the ROCE and relative TSR

metrics. The new Performance Peer Group is as follows:

Baker Hughes Company	ProFrac Holding Corp.
Expro Group Holdings N.V.	RPC, Inc.
Helix Energy Solutions Group, Inc.	Seadrill Limited
Helmerich & Payne, Inc.	SLB N.V.
Liberty Energy Inc.	TechnipFMC plc
Noble Corporation plc	Transocean Ltd.
NOV Inc.	Weatherford International plc
Oceaneering International, Inc.	Valaris Limited
Patterson-UTI Energy, Inc.

58 HALLIBURTON 2026 Proxy Statement www.halliburton.com

With support from its independent compensation consultant, the Compensation Committee selected and approved the

a bove-listed companies because they: (1) have similar cyclicality and capital investment structures as Halliburton; (2) are in

o il and natural gas drilling or oil and natural gas eq uipment and services ; (3) have greater than $1.0 billion market

capitalization; and (4) have a U.S. exchange listing. Further consideration was also given to geography, operations, and

size. When we previewed this new Performance Peer Group with investors during our 2024 shareholder outreach meetings,

they were understanding and supportive of this change.

2025 Executive Compensation Outcomes in Detail

Base Salary

The Compensation Committee generally targets base salaries at the median of the Comparator Peer Group. The

Compensation Committee also considers the following factors when setting base salary:

• Level of responsibility;

• Experience in current role and equitable compensation relationships among internal peers;

• Performance and leadership; and

• External factors involving competitive positioning, general economic conditions, and marketplace compensation trends.

No specific formula is applied to determine the weight of each factor.

Salary reviews are conducted annually to evaluate each executive. Individual salaries are not necessarily adjusted each

year.

The Compensation Committee reviewed the base salary of each of our NEOs, and upon review of the market data and other

relevant factors, the Compensation Committee made the following adjustments to our NEOs’ base s alaries effective January

1, 2025.

NEO	January 1, 2024	January 1, 2025
Mr. Miller	$ 1,650,000	$ 1,700,000
Mr. Carre	$ 910,000	$ 950,000
Mr. Beckwith	$ 835,000	$ 870,000
Mr. Richard	$ 950,000	$ 1,000,000
Mr. Slocum	$ 800,000	$ 925,000

Mr. Miller’s base salary was increased from $1.65 million to $1.70 million in recognition of his performance and to align his

total target direct compensation with the market median of our Comparator Peer Group .

In connection with his promotion to President - Eastern Hemisphere, Mr. Slocum received a 33% increase to his base salary

effective January 1, 2024. Despite this increase, his salary remained below the market median for this role. Consistent with

its practice of aligning salaries to market over a multi-year period, the Committee increased Mr. Slocum’s 2025 base salary

from $800,000 to $925,000 to more closely align his compensation with internal positioning and the market median of the

Comparator Peer Group.

Short-Term (Annual) Incentive

The Annual Performance Pay Plan is designed to provide executives and other key members of management the

opportunity to earn an annual cash bonus based on the annual performance of the Company. The Annual Performance Pay

Plan places a significant percentage of each NEO’s annual cash compensation at risk and aligns the interests of executives

and shareholders. It is administered in accordance with the terms of the Stock and Incentive Plan.

HALLIBURTON 2026 Proxy Statement 59

2025 Target Award Opportunities

Individual incentive award opportunities are established as a percentage of base salary at the beginning of the plan year

based on market-competitive targets. The maximum award a NEO can receive is limited to two times the target opportunity

level. The level of achievement of annual performance determines the dollar amount of incentive compensation payable to

participants following completion of the plan year. The Compensation Committee set incentive award opportunities under the

plan for 2025, which remained unchanged from 2024 levels for all NEOs:

NEO	Threshold	Target	Maximum
Mr. Miller	48%	150%	300%
Mr. Carre	32%	100%	200%
Mr. Beckwith	32%	100%	200%
Mr. Richard	35%	110%	220%
Mr. Slocum	35%	110%	220%

Threshold, Target, and Maximum opportunity dollar amounts can be found in the Grants of Plan-Based Awards in Fiscal

2025 table.

2025 Plan Structure At-A-Glance

During our extensive shareholder outreach efforts over the years, we heard the importance of directly linking compensation

to demonstrated progress on our strategic priorities through objective and measurable goals. As a result, the structure of the

Annual Performance Pay Plan holds our NEOs accountable for making progress towards and then achieving specific

Financial Metrics, which comprise 80% of the annual plan structure. Additionally, our NEOs are incentivized to drive

progress on business-relevant non-financial metrics that support our long-term strategy. These Non-Financial Strategic

Metrics comprise 20% of the annual plan structure. The 2025 Annual Performance Pay Plan is structured as follows:

Measures	Financial Metrics 80% — Net Operating Profit After-Taxes (NOPAT)	Asset Turns	Non-Financial Strategic Metrics 20% — GHG Emissions Reduction Performance	Our People Performance
Weights	60%	20%	15%	5%
Rationale/ Shareholder Alignment	Places emphasis on free cash flow and capital discipline		Links directly to our key sustainable energy and our strategic people priorities

2025 Financial Metrics

For 2025, as discussed above, financial performance under the Annual Performance Pay Plan was based on the

achievement of pre-established performance metrics: Net Operating Profit After-Taxes (NOPAT) and Asset Turns. The

Compensation Committee selected these metrics because they are key financial measures upon which we set our

performance expectations for the year and place an increased emphasis on free cash flow and capital discipline, as

preferred by our shareholders.

NOPAT = Net Operating Profit After Taxes

OPERATING INCOME
+	Interest Income
+	Other Nonoperating Income (Expense), Net
=	NET OPERATING PROFIT
-	Income Taxes
=	NET OPERATING PROFIT AFTER TAXES

ASSET TURNS = Revenue/Net Invested Capital

	Average Net Assets (1)
-	Average Net Liabilities (2)
=	NET INVESTED CAPITAL

(1) Average Net Assets excludes cash and marketable investments, and current and non-current deferred income tax assets.

(2) Average Net Liabilities excludes current and long-term debt, which includes finance lease liabilities, and non-current deferred income

tax liability.

Adjustments in the calculation of NOPAT and Asset Turns may, at times, be approved by the Compensation Committee and

can include the treatment of unusual items that may have impacted our actual results.

At the beginning of each plan year, the Compensation Committee approves an incentive award schedule that equates levels

of performance with cash reward opportunities. The performance goals range from “Threshold” to “Target” to “Maximum”.

Threshold reflects the minimum performance level that must be achieved for an award to be earned and Maximum reflects

the maximum award that can be earned.

Traditionally, the performance goals are based on our annual operating plan, as reviewed and approved by our Board, and

are set at levels to meet or exceed shareholder expectations of our performance, as well as expectations of our performance

relative to our competitors. Given the cyclical nature of our business, our performance goals vary from year to year,

reflecting goals that are consistently rigorous but also reflective of the commodity price environment in which our industry

operates. The Compensation Committee may also consider other business performance factors that are important to our

investors, including health, safety, environment, and service quality, in determining the final payout amounts under the

Annual Performance Pay Plan.

HALLIBURTON 2026 Proxy Statement 61

2025 Non-Financial Strategic Metrics

The 2025 metrics for the Annual Performance Pay Plan include Non-Financial Strategic Metrics focused on two categories:

sustainability (specifically greenhouse gas ( GHG) emissions reduction performance) and our people. The Compensation

Committee selected these categories and their respective metrics and goals at the beginning of the year to intentionally

reflect the Company’s strategy and perspective: the sustainability of our business, the reduction in environmental impacts,

and the enhancement of the economic and social well-being of our employees and the communities in which we live and

work are critical to our success . As such, each goal is also aligned with and measured against key principles designed to

guide the NEOs’ decisions and actions throughout the year.

The Non-Financial Strategic Metrics are binary and limited to a Target award. Award opportunities for each category are 5%

or 10% depending on the number of goals met . The specific metrics, weights and goals in each category that were approved

by the Board for 2025, as well as the actual achievement results, are outlined below :

2025 Metrics	Weight	Key Principles	2025 Goals	Achievement
Convert North America hydraulic fracturing fleet to lower emission footprint	10%	Because about 80% of our corporate Scope 1 and 2 GHG emissions are directly tied to hydraulic fracturing, our fleet mix will drive future emissions reduction by converting fleet to electric, and for emissions intensity, we will be transparent about the impact of our fleet transition.	Exit the year ≥ 9% increase in electric frac spreads	9.5%
Complete additional rounds of prospects for Halliburton Labs	5%	Through Halliburton Labs we invest our scaling resources, experienced team members, and global business network connections to help innovative early stage energy and climate tech companies use their time and capital efficiently to commercialize new solutions and increase company valuation. It provides Halliburton insight into the unmet needs of the evolving value chains beyond our existing business. Pitch days facilitate the Advisory Board selection of program participants. Company Showcase events provide existing Halliburton Labs company participants an additional avenue to showcase their progress and meet with prospective equity capital providers.	Complete three or more events (pitch days or demo days)	3
Ensure appropriate global workforce localization	5%	A workforce that is representative of the locations where we work is important to the countries in which we operate. We hire and develop local workforce talent, while providing opportunities for exposure to other parts of the world.	Greater than 90% of worldwide headcount localized	91%

2025 Performance Results

The performance goals and results are noted in the table below:

Category	Weight	Performance Measures	Threshold	Target	Maximum	Actual

Long-Term Incentives

The Stock and Incentive Plan is designed to reward consistent achievement of value creation and operating performance

goals, align management with shareholder interests, and encourage long-term planning and commitment. Long-term

incentives represent the largest component of total executive compensation opportunity.

Using a mix of incentive vehicles allows us to provide a diversified yet balanced long-term incentive program that effectively

addresses volatility in our industry and in the stock market, in addition to incentivizing our management to meet performance

goals. For the 2025 plan year, the Compensation Committee used the following combination of equity vehicles for long-term

incentive grants:

Vehicle	Weighting	Purpose
Performance Units (1)	70% of Award	Rewards achievement of specific financial goals measured over a three-year performance period
Restricted Stock (2)	30% of Award	Supports leadership retention/stability objectives; five-year vesting period

(1) Performance units vest upon achievement of specific financial goals measured over a three-year performance period and are

denominated 50% in cash and 50% in stock. Dividend equivalents are measured and vest based on the same performance conditions

as the units denominated in stock. Accrued dividend equivalents that vest are paid out in cash.

(2) Restricted stock grants are generally subject to a graded vesting schedule of 20% per year over five years. However, different vesting

schedules may be utilized at the discretion of the Compensation Committee. Shares of restricted stock receive dividends.

Individual Incentive Opportunities

In determining the size of long-term incentive awards, the Compensation Committee first considers market data for

comparable positions and then may adjust the awards upwards or downwards based on the Compensation Committee’s

review of internal equity. This can result in positions of similar scope receiving awards of varying size. Awards are targeted to

the market median. Mr. Miller’s 2025 long-term incentive award was aligned with the market median of our Comparator Peer

Group.

As part of its process, the Compensation Committee reviews and makes decisions about target long-term incentive award

opportunities for the following year during its regular December meeting. Stock grants are then determined by dividing the

grant value by the average of the closing price of our common stock on the NYSE on each business day during the month of

December. The Compensation Committee reviews the final stock grant calculations again in January and determines final

approval. For the 2025 plan year, the Compensation Committee approved restricted stock and performance share grants in

January 2025.

Individual incentive opportunities are established based on market references and the NEO’s role within the organization. In

the Grants of Plan-Based Awards in Fiscal 2025 table, the Threshold, Target, and Maximum columns under the heading

Estimated Future Payouts Under Non-Equity Incentive Plan Awards indicate the potential cash payout for each NEO under

the 2025 PUP cycle, and the Threshold, Target, and Maximum columns under the heading Estimated Future Payouts Under

Equity Incentive Plan Awards indicate the potential shares that can be earned by each NEO for the 2025 PUP cycle. The

potential payouts are performance driven and completely at risk. Actual payouts and shares vesting, if any, will not be

determined until the three-year cycle closes on December 31, 2027.

A Closer Look at the Performance Unit Program

The PUP provides NEOs and other selected executives with incentive opportunities based on our consolidated ROCE

during a three-year performance period. This program reinforces our objectives for sustained long-term performance and

value creation. It also reinforces strategic planning processes and balances short-and long-term decision making.

The program measures ROCE on a relative basis to the results of a performance peer group over three years. The 2025

Performance Peer Group used for the PUP is comprised of oilfield equipment and services companies and oil and gas

contractors. This peer group is used for the PUP because these companies represent the timing, cyclicality, and volatility of

the oil and natural gas industry and provide an appropriate industry group for measuring our relative performance. The 2025

Performance Peer Group is listed on page 57 of this CD&A.

HALLIBURTON 2026 Proxy Statement 63

The three-year performance period aligns this measurement with our and our Performance Peer Group’s business cycles.

ROCE indicates the efficiency and profitability of our capital investments and is determined based on the ratio of earnings

divided by average capital employed. The calculation is as follows:

ROCE	After-tax interest expense
Shareholders’ equity (average of beginning and end of period)	+	Debt (average of beginning and end of period)

Why ROCE? — ●	Highly correlated to stock price performance over the long-term, applying drivers that management can directly influence.	●	Strong support from our shareholders.
●	Aligned with our strategy of delivering industry- leading returns across the business cycle.	●	Eliminates the subjectivity inherent in setting long- term absolute targets in a cyclical industry.
●	Reinforces the Company’s objective for sustained long-term performance and value creation.	●	Provides our management team with a clear line of sight to long-term financial results.

Consistent with our executive compensation objectives and strategy to deliver leading returns in our industry, over the past

ten years we delivered superior ROCE performance relative to our two largest competitors, and our Performance Peer

Group. We believe that this long-term focus on generating superior returns within our industry also correlates with our

industry TSR outperformance over the same period of time.

2023 PUP Cycle

Performance Matrix

At the end of the three-year award cycle, the average ROCE of Halliburton and the Performance Peer Group will be

calculated, and performance percentiles will be determined. Target performance for relative ROCE is set at the 55th

percentile of the Performance Peer Group. Additionally, payout of the primary metric (relative ROCE) is capped at target

when average Halliburton ROCE for the applicable three-year performance period is negative. If Halliburton’s relative

performance ranking is between the 25 th and 75 th percentiles, the payout will be interpolated accordingly. If Halliburton’s

relative performance ranking is below the 25 th percentile, there will not be a payout.

The PUP also uses a relative TSR modifier that compares three-year performance against the constituents of the OSX and

can increase or decrease the incentive opportunity payout by 25%, which adds a long-term performance component to the

PUP directly linked to stock price. For purposes of calculating TSR used in the modifier, a one-month averaging period is

used beginning with the month preceding the performance period and ending with the last month of the performance period.

The modifier imposes an award penalty for bottom quartile performance and an incentive for top quartile performance. If the

TSR is in the upper quartile but negative, the TSR modifier will not apply.

64 HALLIBURTON 2026 Proxy Statement www.halliburton.com

The performance matrix for the 2023 PUP cycle is as follows:

		Unadjusted Incentive Opportunity (2)	Relative TSR Modifier — Lower Quartile Performance ≤25 th percentile	2 nd /3 rd Quartile Performance >25 th percentile & <75 th percentile	Upper Quartile Performance ≥75 th percentile
				MULTIPLIER (3)

	Challenge ≥75 th percentile	200%	150% (200% x 75%)	200% (200% x 100%)	250% (200% x 125%)

(1) If Halliburton’s relative ROCE performance ranking is between the 25 th and 75 th percentiles, the payout will be interpolated accordingly.

(2) If Halliburton ’ s relative ROCE three-year average is negative, the payout will be capped at the target level. The TSR modifier still

applies

(3) If TSR is in the upper quartile but negative, the TSR modifier will not apply.

Any awards earned at the end of the cycle will be issued 50% in stock and 50% in cash.

2023 PUP Cycle Results

The incentive opportunity set for our NEOs for the 2023 PUP cycle was based on Halliburton’s ROCE performance relative

to that of our Performance Peer Group for the three-year period ended December 31, 2025. For this cycle, we achieved

ROCE of 14.36% which was above the 55th percentile and below the 75 th percentile of our Performance Peer Group’s

ROCE of 12.20% and 15.70%, respectively, yielding an unadjusted incentive payout of 161.71% of the target opportunity

level. For the three-year period ended December 31, 2025, we achieved TSR of -18.92%, which was in the bottom quartile

relative to the OSX and resulted in a 25% reduction in the payout, yielding a total payout of 121.28% of the target

opportunity. For purposes of calculating TSR, Halliburton Company is excluded from the peer group, dividends are

reinvested on the ex-dividend date, and a one-month averaging period is used beginning with the calendar month preceding

the beginning of the performance period and ending with the last calendar month of the performance period. The 2023 PUP

Cycle will be paid 50% in cash and 50% in stock. Dividend equivalents are measured and vest based on the same

performance conditions as the units denominated in stock. Dividend equivalents are paid in cash.

The NEOs received cash payments as set forth in the Non-Equity Incentive Plan Compensation column in the Summary

Compensation Table. The equity payment is reported in the 2025 Option Exercises and Stock Vested Table.

2025 PUP Cycle

Performance Matrix

Target performance for relative ROCE is set at the 55 th percentile of the Performance Peer Group. Additionally, payouts of

the primary metrics (relative ROCE) are capped at target when average Halliburton ROCE for the applicable three-year

performance period is negative. The performance matrix for the 2025 PUP cycle is the same as the performance matrix for

the 2023 PUP cycle as outlined above.

Other Executive Benefits and Policies

Stock Ownership Requirements

We have stock ownership requirements for our executive officers, which include all NEOs, to further align their interests with

our shareholders.

Our CEO is required to own Halliburton common stock in an amount equal to or in excess of six times his annual base

salary. Executive officers that report directly to the CEO are required to own Halliburton common stock equal to or in excess

of three times their annual base salary, and all other executive officers are required to own Halliburton common stock in an

HALLIBURTON 2026 Proxy Statement 65

amount equal to or in excess of two times their annual base salary. The Compensation Committee reviews their holdings,

which include restricted shares, SEUs, RSUs, and all other Halliburton common stock owned by the officer, at each

December meeting. Each executive officer has five years to meet the requirements, measured from the date the officer

becomes subject to the ownership level for the applicable office.

After the five-year stock ownership period described above, executive officers who have not met their minimum ownership

requirement must retain 100% of the net shares acquired upon restricted stock vesting until they achieve their required

ownership level. Also, any stock option exercise must be an exercise and hold.

As of December 31, 2025, all NEOs met the requirements.

Policies and Practices Related to the Grant of Certain Equity Awards

Equity awards granted to executive officers and other employees consist of restricted stock, restricted stock units, and

performance-based awards. These awards are generally approved by the Compensation Committee during its regularly

scheduled meetings, with award values established based on market data and internal compensation considerations, and

the number of shares determined using an average closing price methodology over a defined period.

The Compensation Committee does not grant equity awards in anticipation of the release of material nonpublic information,

does not time the release of material nonpublic information based on equity award grant dates, and does not consider

material nonpublic information when determining the timing, terms, or value of equity awards.

Since 2020, the Compensation Committee has not used stock options or stock appreciation rights as a component of

executive or other employee compensation, and accordingly, the Company does not maintain a formal policy governing the

timing of stock options or stock appreciation right grants.

Clawback Policy

We have a clawback policy, as required by the SEC and NYSE, under which we will seek to recoup incentive-based

compensation received by any of our current or former executive officers, which includes all NEOs, if and to the extent that

the Company is required to prepare an applicable accounting restatement. The recovery period includes the three

completed fiscal years immediately preceding the restatement date and any transition period (resulting from a change in the

Company’s fiscal year) of less than nine months within or immediately following those completed fiscal years. Incentive-

based compensation includes any compensation granted, earned, or vested based wholly or in part on the attainment of a

financial reporting measure, and the amount recoverable will be the difference between what was received by the executive

officer and what should have been received if it had been determined based on the restatement amounts, computed without

regard to any taxes paid.

The Board shall determine any restatement date and the Chief Financial Officer shall, with the approval of the

Compensation Committee, calculate the recoverable compensation for each affected executive officer. The Compensation

Committee shall determine the method of recovering any recoverable compensation, so long as it complies with Section

303A.14 of the NYSE Listed Company Manual. The Compensation Committee shall interpret and construe the policy and

make any determinations required to be made in recovering the recoverable compensation.

The Company shall not indemnify any current or former executive officer against the loss of recoverable compensation and

shall not pay or reimburse any current or former executive officer for premiums for any insurance policy to fund such

executive officer’s potential recovery obligations. No restatements have occurred during the last fiscal year. A copy of the

policy was filed as an exhibit to the 2024 Form 10-K.

In addition, during 2024, the Company adopted a new supplemental recoupment policy under which we may seek, in

appropriate cases, to recoup incentive-based compensation, including both time- and performance-vesting awards paid to,

awarded to, or credited for the benefit of any of our executive officers, which includes all NEOs, if and to the extent that they

breached their fiduciary duty through a knowing or reckless material violation of law, breached the Code of Business

Conduct in a matter that results in, or could reasonably expect to result in, material, reputational, or financial harm to the

Company, or had direct supervisory authority over an employee who participated in such violation and such officer

disregarded their own supervisory responsibilities. We may also recoup incentive-based compensation if an officer is named

as a defendant for the actions described above, and we either determine that the action is not indemnifiable or the officer

does not prevail at trial.

The disinterested members of the Board and the disinterested members of the Compensation Committee and the

Nominating and Corporate Governance Committee may be involved in reviewing, considering, and making determinations

regarding the officer’s alleged conduct, whether recoupment is appropriate or required, and the type and amount of incentive

compensation to be recouped from the officer. There was no recoupment under the supplemental policy in 2025.

66 HALLIBURTON 2026 Proxy Statement www.halliburton.com

Hedging and Pledging Policy

We have a policy under which our Directors and executive officers, which includes all NEOs, and certain senior officers are

prohibited from:

• hedging activities related to Halliburton securities; and

• the pledging of Halliburton securities.

The policy defines hedging activities as the use of any financial instrument designed to hedge or offset a change in the

market value of any Halliburton security and defines pledging as the use of a Halliburton security or any related derivative

security as collateral for any form of indebtedness.

Additionally, the policy:

• discourages all employees and Directors from speculative activities in Halliburton securities and related derivative

securities, such as puts or call options;

• applies to all Halliburton securities, including restricted stock, restricted stock units, options, and debt securities, which are

issued by any Halliburton entity, and any other security directly or indirectly exercisable for or convertible or exchangeable

into any Halliburton security; and

• applies regardless of whether or not the securities were acquired from our equity compensation plans.

Retirement and Savings Plan

All NEOs may participate in the Halliburton Retirement and Savings Plan, which is the defined contribution benefit plan

available to all eligible U.S. employees. The matching contribution amounts we contributed on behalf of each NEO are

included in the Supplemental Table: All Other Compensation.

Supplemental Executive Retirement Plan

The objective of the Supplemental Executive Retirement Plan (SERP) is to provide a competitive level of pay replacement

upon retirement. The current pay replacement target is 75% of base salary at age 65 with 25 years of service, using the

highest annual salary during the last three years of employment.

The material factors and guidelines considered in making an allocation include: (i) retirement benefits provided, both

qualified and nonqualified; (ii) current compensation; (iii) length of service; and (iv) years of service to normal retirement.

The calculation takes into account the following variables: (i) base salary; (ii) years of service; (iii) age; (iv) employer portion

of qualified plan savings; (v) age 65 value of any defined benefit plan; and (vi) existing nonqualified plan balances and any

other retirement plans.

Several assumptions are made annually and include a base salary increase percentage, qualified and nonqualified plan

contributions and investment earnings, and an annuity rate. These factors are reviewed and approved annually by the

Compensation Committee in advance of calculating any awards.

To determine the annual benefit, external actuaries calculate the total lump sum retirement benefit needed at age 65 from all

company retirement sources to produce an annual retirement benefit of 75% of the highest annual salary during the last

three years of employment. Company retirement sources include any Company contributions to qualified benefit plans and

contributions to nonqualified benefit plans. If the combination of these two sources does not yield a total retirement balance

that will meet the 75% objective, then contributions may be made annually through the SERP to bring the total benefit up to

the targeted level.

To illustrate, assume $10 million is needed at age 65 to produce an annual retirement benefit equal to 75% of base salary.

The participant is projected to have $3 million in qualified benefit plans resulting from Company contributions at retirement

and $4 million in nonqualified retirement plans resulting from Company contributions at retirement. Since the total of these

two sources is $7 million, a shortfall of $3 million results. This is the amount needed to achieve the 75% pay replacement

objective. This shortfall may be offset through annual contributions to the SERP.

Participation in the SERP is limited to the direct reports of the CEO and other selected executives as recommended by the

CEO and approved at the discretion of the Compensation Committee. However, participation one year does not guarantee

future participation. In 2025, the Compensation Committee authorized retirement allocations under the SERP to all NEOs.

Amounts allocated during 2025 are listed in the Supplemental Table: All Other Compensation and the 2025 Nonqualified

Deferred Compensation table.

All of the NEOs, except Mr. Beckwith, are fully vested in their respective account balances. Balances for active and

terminated participants earn interest at an annual rate of 5% and 10%, respectively.

HALLIBURTON 2026 Proxy Statement 67

Elective Deferral Plan

All NEOs may participate in the Halliburton Elective Deferral Plan, which was established to provide highly compensated

employees with an opportunity to defer earned base salary and incentive compensation to help meet retirement and other

future income needs.

Participants may elect to defer up to 75% of their annual base salary and up to 75% of their incentive compensation into the

plan. Deferral elections must be made on an annual basis, including the type and timing of distribution. Plan earnings are

based on the NEO’s choice of up to 12 investment options with varying degrees of risk, including the risk of loss. Investment

options may be changed by the NEO daily.

In 2025, none of our NEOs elected to defer compensation under this plan. Messrs. Richard and Slocum have account

balances from deferral elections under the plan in prior years. Messrs. Miller, Carre, and Beckwith have not made any

deferral elections under the plan. Further details can be found in the 2025 Nonqualified Deferred Compensation table.

Benefit Restoration Plan

The Halliburton Company Benefit Restoration Plan provides a vehicle to restore qualified plan benefits that are reduced as a

result of limitations on contributions imposed under the Internal Revenue Code (IRC) or due to participation in other plans

we sponsor and to defer compensation that would otherwise be treated as excessive remuneration within the meaning of

IRC Section 162(m). Awards are made annually to those who meet these criteria and earn interest at an annual rate as

defined by the plan document. Awards and corresponding interest balances are 100% vested and distributed upon

separation.

In accordance with the plan document, participants earn monthly interest at the Internal Revenue Service Monthly Long-

Term 120% AFR rate, provided the interest rate shall be no less than 6% per annum and no greater than 10% per annum.

Because the 120% Monthly AFR rate was below the 6% minimum interest threshold, plan participants earned interest at an

annual rate of 6% in 2025.

In 2025, all NEOs received awards under this plan in the amounts included in the Supplemental Table: All Other

Compensation and the 2025 Nonqualified Deferred Compensation table.

Perquisites

We do not pay for tax gross ups for personal use of corporate aircraft, executive physical examinations, financial planning,

or country club dues for our NEOs. We do not provide cars to our NEOs. However, a car and part-time driver is available for

Mr. Miller’s limited use as needed for security purposes and so that he can work while in transit to meet customers or attend

business-related functions.

We provided security at the personal residences of Mr. Miller during 2025.

As a result of the recommendations provided by an independent, third-party security consultant, the Board has determined

that Mr. Miller must use company aircraft for all travel. The security study also recommends that his spouse and children use

company-provided aircraft.

Specific amounts for the only available perquisites are detailed in the Supplemental Table: All Other Compensation.

Elements of Post-Termination Compensation and Benefits

Termination events that trigger payments and benefits include normal or early retirement, cause, death, disability, and

voluntary termination. Post-termination or change-in-control payments with qualifying termination may include severance,

accelerated vesting of restricted stock and stock options, payments under cash-based short- and long-term incentive plans,

share vesting under the long-term incentive plan, payout of nonqualified account balances, and health benefits, among

others. The impact of various events on each element of compensation for the NEOs is detailed in the Post-Termination or

Change-In-Control Payment table.

68 HALLIBURTON 2026 Proxy Statement www.halliburton.com

Impact of Regulatory Requirements on Compensation

IRC Section 162(m) generally disallows a tax deduction to public companies for compensation paid to the CEO, CFO, or any

of the three other most highly compensated officers (“covered employees”) to the extent the compensation exceeds $1

million in any year. Effective for tax years beginning after December 31, 2017, Section 162(m) has been revised to eliminate

the performance-based compensation exception and to provide that an individual who is a covered employee for 2017 or

any later tax year will continue to be a covered employee for all subsequent taxable years, including years after the death of

the individual.

Although the tax deductibility of compensation is a consideration evaluated by our Compensation Committee, the Committee

believes that the elimination of the deduction on compensation payable in excess of the $1 million limitation for our NEOs is

not material relative to the benefit of being able to attract and retain talented management. Accordingly, our Compensation

Committee will continue to pay compensation that is not deductible.

Salary. The amounts in the Salary column reflect the salary earned by each NEO.

Stock Awards . The amounts in the Stock Awards column reflect the aggregate grant date fair value of the restricted stock

and performance shares awarded in 2025. Each amount reflects an accounting expense and does not correspond to actual

value that may be realized by a NEO in the future. Except where there is a distinction to make between the two types of

awards, this proxy statement refers to both restricted stock and restricted stock units as “restricted stock.” We calculate the

fair value of restricted stock awards by multiplying the number of restricted shares or restricted stock units granted by the

closing stock price on the grant date. For the performance shares, a Monte Carlo simulation that uses a probabilistic

approach was performed by an actuary to determine grant date fair value. The NEOs may never realize any value from

these performance shares and, to the extent that they do, the amounts realized may be different than the amounts reported

above.

Non-Equity Incentive Plan Compensation. The Non-Equity Incentive Plan Compensation column reflects amounts earned

in 2025 for the 2025 Halliburton Annual Performance Pay Plan and the award amount payable in cash for the 2023 PUP

cycle.

The 2025 Halliburton Annual Performance Pay Plan amounts paid to each NEO are: $1,657,500 for Mr. Miller; $617,500 for

Mr. Carre; $565,500 for Mr. Beckwith; $715,000 for Mr. Richard; and $661,375 for Mr. Slocum.

The 2023 PUP cycle amounts paid to each NEO are: $4,287,336 for Mr. Miller; $1,197,483 for Mr. Carre; $1,197,483 for

Mr. Beckwith; $1,561,694 for Mr. Richard; and $327,463 for Mr. Slocum. The amounts paid to the NEOs for the 2023 PUP

cycle differ from what is shown in the Grants of Plan-Based Awards in Fiscal Year 2025 table under Estimated Future

Payments Under Non-Equity Incentive Plan Awards. That table indicates the potential award amounts payable in cash under

the 2025 PUP cycle, which will close on December 31, 2027.

Change in Pension Value and NQDC Earnings . The amounts in the Change in Pension Value and NQDC Earnings

column are attributable to the above-market earnings for various nonqualified plans. The methodology for determining what

constitutes above-market earnings is the difference between the interest rate as stated in the applicable nonqualified plan

70 HALLIBURTON 2026 Proxy Statement www.halliburton.com

document and the Internal Revenue Service Annual Long-Term 120% AFR rate as of December 31, 2025. The 120% Annual

AFR rate used for determining above-market earnings in 2025 was 5.47%.

Supplemental Executive Retirement Plan Above-Market Earnings. The current interest rate for active participant accounts in

the Supplemental Executive Retirement Plan is 5% as defined by the plan document. Because the 120% Annual AFR rate of

5.47% is above the interest rate earned by participants, there were no above-market earnings for the Supplemental

Executive Retirement Plan for 2025.

Benefit Restoration Plan Above-Market Earnings . In accordance with the plan document, participants earn monthly interest

at the Internal Revenue Service Monthly Long-Term 120% AFR rate, provided the interest rate shall be no less than 6% per

annum and no more than 10% per annum. Because the 120% Annual AFR rate was below the 6% minimum interest

threshold, the above-market earnings associated with this plan were 0.53% (6% minus 5.47%) for 2025.

NEOs earned above-market earnings for their balances associated with the plan as follows: $6,562 for Mr. Miller; $2,951 for

Mr. Carre; $860 for Mr. Beckwith; $2,282 for Mr. Richard; and $654 for Mr. Slocum.

Elective Deferral Plan Above-Market Earnings . The average NEO earnings for the balances associated with the Elective

Deferral Plan were 15.50% for 2025 . The above-market earnings associated with this plan equaled 10.03% (15.50% minus

5.47%) for 2025.

NEOs earned above-market earnings for their balances associated with the plan as follows: $75,293 for Mr. Richard; and

$97,744 for Mr. Slocum.

The amounts shown in this column differ from the amounts shown for the Supplemental Executive Retirement Plan, the

Benefit Restoration Plan, and the Elective Deferral Plan in the 2025 Nonqualified Deferred Compensation table under the

Aggregate Earnings in Last Fiscal Year column because that table includes all earnings and losses, and the Summary

Compensation Table shows above-market earnings only.

All Other Compensation. Detailed information for amounts included in the All Other Compensation column can be found in

the Supplemental Table: All Other Compensation.

Supplemental Table: All Other Compensation

The following table details the components of the All Other Compensation column of the Summary Compensation Table for

HALLIBURTON 2026 Proxy Statement 71

Halliburton Political Action Committee . HALPAC allows NEOs and other eligible employees to donate to political

candidates and participate in the political process. We match NEO and other employee donations that are greater than $100

annually to HALPAC dollar-for-dollar to a 501(c)(3) status nonprofit organization of the contributor’s choice. The amounts

shown represent the match amounts donated to charities on behalf of the NEOs in 2025.

Restricted Stock Dividends. This is the amount of dividends paid on restricted stock held by NEOs in 2025. Restricted

stock units granted to employees do not receive dividend payments.

Retirement and Savings Plan Employer Match . This is the matching contribution we made on behalf of each NEO to the

Halliburton Retirement and Savings Plan, our defined contribution plan. We match employee contributions up to 5% of each

employee’s eligible base salary up to the 401(a)(17) compensation limit of $350,000 in 2025 .

Retirement and Savings Plan Basic Contribution . This is the basic contribution we made on behalf of each NEO to the

Retirement and Savings Plan. If actively employed on December 31, 2025, or if they meet retirement eligibility requirements

of the plan as of their separation date, each employee received a contribution equal to 3% of their eligible base pay up to the

401(a)(17) compensation limit of $350,000 in 2025.

Benefit Restoration Plan . This is the award earned under the Benefit Restoration Plan in 2025 as discussed in the Benefit

Restoration Plan section of Compensation Discussion and Analysis. Associated interest, awards, and beginning and ending

balances for the Benefit Restoration Plan are included in the 2025 Nonqualified Deferred Compensation table.

Supplemental Executive Retirement Plan . This is the award approved under the Supplemental Executive Retirement Plan

in 2025 as discussed in the Supplemental Executive Retirement Plan section of Compensation Discussion and Analysis.

Associated interest, awards, and beginning and ending balances for the Supplemental Executive Retirement Plan are

included in the 2025 Nonqualified Deferred Compensation table.

Expatriate Assignment . In 2025, Mr. Slocum received compensation associated with his expatriate assignment similar in

type to that received by other expatriates on comparable assignments. Mr. Slocum received $79,198 for cost-of-living

adjustment; $92,500 for mobility premium; $968,717 for tax equalization; $302,493 for housing allowance; $13,069 for auto

allowance; $15,935 for dependent education; and $360 for miscellaneous reimbursement.

All Other.

As a result of the recommendations provided by an independent, third-party security consultant, the Board has determined

that Mr. Miller must use company aircraft for all travel. The security study also recommends that his spouse and children use

company-provided aircraft. For 2025, the incremental cost to us for this personal use of our aircraft was $155,662 for Mr.

Miller. For total compensation purposes in 2025, we valued the incremental cost of the personal use of aircraft using a

method that takes into account: landing, parking, hanger, flight planning services, and dead-head costs; crew travel

expenses; supplies and catering; aircraft fuel and oil expenses per hour of flight; any customs, foreign permit, and similar

fees; and passenger ground transportation. NEOs are not reimbursed for the tax impact of any imputed income resulting

from aircraft usage. The remaining All Other compensation for Mr. Miller includes home security based on risk assessments

and a car and part-time driver for Mr. Miller’s limited use as needed for security purposes and to work in transit to meet

customers or attend business-related functions.

The value realized for vested restricted stock awards was determined by multiplying the fair market value of the shares

(closing price of our common stock on the NYSE on the vesting date) by the number of shares that vested. Restricted

shares vested on various dates throughout the year. The value listed represents the aggregate value of all shares that

vested for each NEO in 2025.

The value realized for vested performance shares awards was determined by multiplying the fair market value of the shares

(closing price of our common stock on the NYSE on December 31, 2025) by the number of shares that vested.

2025 Nonqualified Deferred Compensation

The 2025 Nonqualified Deferred Compensation table reflects balances in our nonqualified plans as of January 1, 2025,

Employment Contracts and Change-in-Control

Arrangements

Employment Contracts

Each of our NEOs has an employment agreement with us that contains substantial non-compete and non-solicitation

provisions that apply post-separation.

Each employment agreement provides that if the agreement is terminated by the NEO for good reason or by death,

disability, or retirement or his employment is terminated by the Company for any reason other than cause or a fiduciary

violation, all restrictions on restricted stock and units will lapse. In addition, in the case of a termination by the NEO for good

reason or termination by the Company for any reason other than cause or a fiduciary violation, the NEO will receive a lump

sum cash payment equal to two years of base salary. These payments and benefits are subject to the NEO’s execution of a

release of claims in favor of the Company.

Change-in-Control Arrangements

We do not maintain individual change-in-control agreements or provide for excise tax gross-ups on any payments

associated with a change-in-control. Some of our compensation plans, however, contain change-in-control provisions, which

could result in payment of specific benefits.

Under the Stock and Incentive Plan, in the event of a change-in-control, awards are subject to double-trigger vesting, such

that, if a participant is terminated due to involuntary termination without cause, death, disability, good reason (as defined in

an employment agreement, or a similar constructive termination event, in each case, only if a severance benefit is payable

upon termination of employment due to such event pursuant to an employment agreement), or other event as specified in

the participant’s award document within the period beginning on the date of the public announcement of a transaction that, if

consummated, would constitute a change-in-control and ending on the date that is the earlier of the announcement of the

termination of the proposed transaction or two years after the consummation of the transaction (a Qualifying Termination),

the following will occur automatically:

• any outstanding options and stock appreciation rights shall become immediately vested and fully exercisable for the full

term thereof;

• any restrictions on restricted stock awards shall immediately lapse;

• all performance measures upon which an outstanding performance award is contingent are deemed achieved and the

holder shall receive a payment equal to the target amount of the award he or she would have been entitled to receive; and

• any outstanding cash awards, including stock value equivalent awards, immediately vest and are paid based on the

vested value of the award.

Under the Annual Performance Pay Plan:

• in the event of a change-in-control during a plan year, a participant experiencing a Qualifying Termination will be entitled to

payment equal to the target amount of the award he or she would have been entitled to receive, without proration; and

• in the event of a change-in-control after the end of a plan year but before the payment date, a participant will be entitled to

an immediate cash payment equal to the incentive earned for the plan year.

Under the Performance Unit Program:

• in the event of a change-in-control during a performance cycle, a participant experiencing a Qualifying Termination will be

entitled to both a payment equal to the target amount of the cash award he or she would have been entitled to receive and

the vesting of the target amount of performance shares awarded, without proration; and

• in the event of a change-in-control after the end of a performance cycle but before the payment date, a participant will be

entitled to an immediate payment equal to the cash award earned and the vesting of performance shares earned for that

performance cycle.

Under the Employee Stock Purchase Plan, in the event of a change-in-control, unless the successor corporation assumes or

substitutes new stock purchase rights:

• the purchase date for the outstanding stock purchase rights will be accelerated to a date fixed by the Compensation

Committee prior to the effective date of the change-in-control; and

• upon such effective date, any unexercised stock purchase rights will expire and we will refund to each participant the

amount of his or her payroll deductions made for purposes of the Employee Stock Purchase Plan that have not yet been

used to purchase stock.

Early Retirement With Approval or Normal Retirement

Early Retirement. A NEO becomes eligible for early retirement when the NEO has attained age 55 with ten years of service

or when the NEO’s age and years of service equals 70. Eligibility for early retirement does not guarantee retention of stock

awards (lapse of forfeiture restrictions on restricted stock and ability to exercise outstanding options for the remainder of the

stated term) or the pro rata distribution of performance awards, if earned. Early retirement eligibility is a condition that must

be met before the Compensation Committee will consider retention of stock awards and pro rata participation in

performance awards upon separation from employment. For example, if a NEO is eligible for early retirement but is leaving

us to go to work for a competitor, then the NEO’s stock awards would not be considered for retention.

Normal Retirement. A NEO becomes eligible for normal retirement at age 65 and, under our mandatory retirement policy ,

must retire by the last day of the calendar year in which they reach that age.

The following actions will occur for the NEO’s various elements of compensation under Early Retirement with Approval or

Normal Retirement scenarios.

• Severance Pay. No severance would be paid to the NEO.

• Annual Performance Pay Plan. If the NEO retires prior to the end of the plan year for any reason other than death or

disability, the NEO would forfeit any payment due under the plan, unless the Compensation Committee determines that

the payment should be prorated for the partial plan year.

• Restricted Stock. Any stock holdings restrictions would lapse upon the date of retirement. Restricted stock holdings

information can be found in the Outstanding Equity Awards at Fiscal Year End 2025 table.

• Stock Options. The NEO will be granted retention of the NEO’s option awards. The unvested awards will continue to vest

per the vesting schedule outlined in the NEO stock option agreements and any vested options will not expire until ten

years from the grant award date. Stock option information can be found in the Outstanding Equity Awards at Fiscal Year

End 2025 table.

• Performance Cash. The NEO will participate on a prorated basis for any PUP cycles that have not been completed at the

time of the NEO’s retirement. These payments, if earned, are paid out and the NEO would receive payments at the same

time as other participants, which is usually no later than March of the year following the close of the cycle. In the case of

mandatory retirement, the Compensation Committee may, at its discretion, authorize full participation without proration for

any PUP cycles that have not been completed as of the NEO ’ s retirement date.

• Performance Shares. The NEO will participate on a prorated basis for any PUP cycles that have not been completed at

the time of the NEO’s retirement. The shares, if earned, are vested and the NEO would receive the performance shares at

the same time as other participants, which is usually no later than March of the year following the close of the cycle. In the

case of mandatory retirement, the Compensation Committee may, at its discretion, authorize full participation without

proration for any PUP cycles that have not been completed as of the NEO ’ s retirement date.

• Nonqualified Plans. The NEO is entitled to any vested benefits under the applicable nonqualified plans as shown in the

2025 Nonqualified Deferred Compensation table. Payments from the Supplemental Executive Retirement Plan and

Benefit Restoration Plan are paid out of an irrevocable grantor trust. The principal and income of the trust are treated as

our assets and income for federal income tax purposes and are subject to the claims of our general creditors to the extent

provided in the plan. The Elective Deferral Plan is unfunded and we make payments from our general assets. Payments

from these plans may be paid in a lump sum or in annual installments for a maximum ten-year period.

Resignation, Early Retirement Without Approval, or Termination for Cause

Resignation. Resignation is defined as leaving employment with us voluntarily, without having attained early or normal

retirement status (see the applicable sections above for information on what constitutes these statuses).

Early Retirement (Without Approval). Early Retirement is defined as leaving employment with us voluntarily, having

attained early retirement status (see the applicable sections above for information on what constitutes this status). For

example, if a NEO is eligible for early retirement, but leaves the Company to go to work for a competitor, their Early

Retirement generally would not be approved.

Termination (For Cause). A termination for Cause would occur for a reason such as violating our Code of Business

Conduct.

HALLIBURTON 2026 Proxy Statement 79

The following actions will occur for the NEO’s various elements of compensation under Resignation, Early Retirement

Without Approval, or Termination for Cause scenarios.

• Severance Pay. No severance would be paid to the NEO.

• Annual Performance Pay Plan. No payment would be made to the NEO under the Annual Performance Pay Plan.

• Restricted Stock. Any restricted stock holdings would be forfeited upon the date of separation. Restricted stock holdings

information can be found in the Outstanding Equity Awards at Fiscal Year End 2025 table.

• Stock Options. The NEO must exercise outstanding, vested options within 90 days after the NEO’s separation or the

options will be forfeited as per the terms of the stock option agreements. Any unvested stock options would be forfeited.

Stock option information can be found in the Outstanding Equity Awards at Fiscal Year End 2025 table.

• Performance Cash. The NEO would not be eligible to receive payments under the Performance Unit Program.

• Performance Shares. The NEO would not be eligible to receive performance shares under the Performance Unit Program.

• Nonqualified Plans. The NEO would be entitled to any vested benefits under the applicable nonqualified plans as shown in

the 2025 Nonqualified Deferred Compensation table. Refer above to Early Retirement with Approval or Normal Retirement

for more information on Nonqualified Plans.

Termination (Without Cause). Should we terminate a NEO without cause, such as termination at our convenience, then

the provisions of the NEO’s employment agreement related to severance payments and lapsing of stock restrictions would

apply. Payments for these items are conditioned on a release agreement being executed by the NEO. The impact on the

NEO’s various elements of compensation is the same as described under Early Retirement with Approval or Normal

Retirement except as follows:

• Severance Pay. Severance is paid according to terms of the applicable employment agreement. Each NEO would receive

severance in the amount of two times base salary at the time of termination.

• Performance Cash. No payment would be paid to the NEO under the Performance Unit Program.

• Performance Shares. No performance shares would be vested under the Performance Unit Program.

Change-in-Control with Qualifying Termination. Should we terminate a NEO in a Qualifying Termination as part of a

change-in-control, then the provisions of the NEO’s employment agreement related to severance payments and lapsing of

stock restrictions would apply. Payments for these items are conditioned on a release agreement being executed by the

NEO. The impact on the NEO’s various elements of compensation is the same as described under Termination (Without

Cause) except as follows:

• Annual Performance Pay Plan. A NEO experiencing a Qualifying Termination will be entitled to a payment equal to the

target amount of the award the NEO would have been entitled to receive, without proration. Assuming the change-in-

control occurred on the last business day of the year, no additional amounts under the plan would be paid. The actual

amounts paid for 2025 are reflected in the Summary Compensation Table and described in the Non-Equity Incentive Plan

Compensation narrative to that table. If a Qualifying Termination occurred on any other date, a NEO would receive the

target amount of the award, as shown in the Grants of Plan-Based Awards in Fiscal 2025 table.

• Restricted Stock. Restricted shares granted under the Stock and Incentive Plan will vest in the event of a Qualifying

Termination. Restricted stock holdings information can be found in the Outstanding Equity Awards at Fiscal Year End 2025

table.

• Performance Cash. A NEO experiencing a Qualifying Termination will be entitled to a payment equal to the target amount

of the award the NEO would have been entitled to receive, without proration. Assuming the change-in-control occurred on

the last business day of the year, no additional amounts under the PUP plan would be paid for the 2023 PUP cycle. The

actual amounts paid for that cycle are reflected in the Summary Compensation Table and described in the Non-Equity

Incentive Plan Compensation narrative to that table. The Post-Termination or Change-in-Control Payments table reflects

the target award amounts that would be paid for the 2024 and 2025 PUP cycles.

• Performance Shares. A NEO experiencing a Qualifying Termination will be entitled to share vesting equal to the target

amount of the award the NEO would have been entitled to receive, without proration. Assuming the change-in-control

occurred on the last business day of the year, no additional shares would vest under the PUP plan for the 2023 PUP

cycle. The actual shares that vested for that cycle are reflected in a Form 4 filed by each NEO. The table reflects the

target award shares that would vest, valued at the closing price of our common stock on the NYSE on December 31,

2025, for the 2024 and 2025 PUP cycles.

A change-in-control without a Qualifying Termination has no effect on NEO compensation.

CEO Pay Ratio

For 2025, the annual total compensation of our CEO was 186 times the median of the annual total compensation of all

employees, based on annual total compensation of $16,539,020 for the CEO and $88,698 for the median employee.

This disclosure is based on an October 1, 2023, employee population of 47,429, of which 15,222 were U.S. employees and

32,207 were non-U.S. employees, and remains representative of current employee population . We excluded from this

employee population 2,289 non-U.S. employees from 43 countries as the total number of employees from these non-U.S.

jurisdictions was less than 5% of our total employee population. After applying the exclusion, the total employee population

was 45,140.

Non-U.S. Employee Country Exclusions — Country	Headcount	Country	Headcount	Country	Headcount	Country	Headcount
Albania	6	Ecuador	488	Kazakhstan	186	South Africa	1
Austria	8	Equatorial Guinea	6	Kenya	2	South Korea	2

Denmark	30	Japan	16	Senegal	67

The median employee was identified using base pay, overtime pay, bonuses, allowances, and premiums. We used the total

gross wages of all employees as of our determination date of October 1, 2023, as a reasonable estimate of the median total

gross wages for the employee population and identified all employees within 1% of the median total gross wages. From this

group we selected an employee as a reasonable representative of our median employee. Annual total compensation for

both the CEO and the median employee was calculated in accordance with Item 402(c)(2)(x) of Regulation S-K. We did not

identify a new median employee this year because there has been no change in our employee population or employee

compensation arrangements that we reasonably believe would significantly impact our pay ratio disclosure.

The annual total compensation for our CEO includes both the amount reported in the “Total” column of our Summary

Compensation Table, $16,525,407, and the estimated value of our CEO’s health and welfare benefits, $13,613. Due to the

flexibility afforded in calculating the CEO pay ratio, the ratio may not be comparable to CEO pay ratios presented by other

companies.

Proposal No. 4 Approval of the

Halliburton Energy Services, Inc.

Charter Amendment

General Information

On December 9, 1996, Halliburton Energy Services, Inc. (HESI) announced plans to implement a holding company

reorganization (Holding Company Reorganization). On December 12, 1996, HESI implemented the Holding Company

Reorganization pursuant to Section 251(g) of the General Corporation Law of the State of Delaware (DGCL). As a result of

the Holding Company Reorganization, HESI became a wholly owned subsidiary of the Company, and the Company became

the new parent company of and the successor issuer to HESI and replaced HESI as the public company trading on the

NYSE under the ticker symbol “HAL”.

As required by Section 251(g) of the DGCL, in connection with the Holding Company Reorganization, HESI’s Certificate of

Incorporation was amended (as amended and restated to date, the HESI Charter) to provide that any act or transaction by

or involving HESI that requires the approval of HESI’s shareholders will also require the approval of the Company’s

shareholders by the same vote that is required by the DGCL and the HESI Charter (the Pass-Through Voting Provision).

Accordingly, the Pass-Through Voting Provision gives the Company’s shareholders direct voting rights with respect to

matters affecting HESI that would otherwise only require the approval of the Company’s subsidiary that is the sole

shareholder of HESI. Absent a provision like the Pass-Through Voting Provision, there is no general requirement under

Delaware law that shareholders of a parent entity be given the right to vote on transactions involving the parent entity’s

wholly owned subsidiaries.

The Board seeks approval from the Company’s shareholders to amend the HESI Charter to remove the Pass-Through

Voting Provision (the HESI Charter Amendment), which is an unusual requirement and a limitation on administrative and

operational flexibility. Among other things, the elimination of the Pass-Through Voting Provision would allow the Company’s

subsidiary that is the sole shareholder of HESI to approve certain corporate acts relating to HESI without the additional

approval of the Company’s shareholders. The Pass-Through Voting Provision, which will be removed from the HESI Charter

if the proposed HESI Charter Amendment is approved, reads as follows:

FIFTEENTH: Any act or transaction by or involving the Corporation that requires for its adoption under the

General Corporation Law of the State of Delaware or its certificate of incorporation the approval of the stockholders

of the Corporation shall, by virtue of this reference to Section 251(g) of the General Corporation Law of the State of

Delaware, require, in addition, the approval of the stockholders of Halliburton Company, a Delaware corporation

(formerly Halliburton Hold Co.), or any successor thereto by merger, so long as such corporation or its successor is

the ultimate parent, directly or indirectly, of this Corporation, by the same vote that is required by the General

Corporation Law of the State of Delaware and/or the certificate of incorporation of this Corporation. For the

purposes of this Article FIFTEENTH, the term “parent” shall mean a corporation that owns, directly or indirectly, at

least a majority of the outstanding capital stock of this Corporation entitled to vote in the election of directors of this

Corporation without regard to the occurrence of any contingency.

A complete copy of the proposed HESI Charter Amendment is attached to this proxy statement as Appendix A .

Reasons for the HESI Charter Amendment

The Company operates in more than 70 countries worldwide and has over 280 s ubsidiaries , none of which, with the

exception of HESI, require approval of the Company’s shareholders to take certain corporate actions. The removal of the

Pass-Through Voting Provision will put the Company in the same position as substantially all other public holding companies

that operate through multiple subsidiaries. It is uncommon for the shareholders of such public holding companies to have

direct voting rights as to matters that affect only subsidiaries of the holding company. By removing this requirement, the

Company will gain the flexibility and efficiency currently realized by nearly all other companies that operate under the same,

or similar, structures.

Under Delaware law, certain acts, such as a change in domicile or the conversion of a wholly owned subsidiary from a

corporation into a limited liability company, would require the approval of the parent corporation as the sole shareholder of

the subsidiary, but would not normally require a vote of the shareholders of the parent corporation. However, if the Pass-

HALLIBURTON 2026 Proxy Statement 89

Through Voting Provision were to be retained in the HESI Charter, then such acts would require the approval of the

Company’s shareholders.

Obtaining the approval of the shareholders of a public corporation would significantly delay HESI’s ability to complete certain

actions and increase its costs, including through scheduling a vote, whether at a regular annual shareholders’ meeting or at

a special meeting, of the Company’s shareholders. To avoid such delays and costs, and to provide maximum flexibility and

efficiency under the Company’s holding company structure, the Company proposes to remove the Pass-Through Voting

Provision from the HESI Charter. Removing the Pass-Through Provision from the HESI Charter would have no effect on the

rights of shareholders of the Company to vote on matters relating to the Company. Following the removal of the Pass-

Through Voting Provision from the HESI Charter, shareholders of the Company would continue to have the voting rights

typically provided to shareholders of a public holding company by Delaware law.

Impact on Shareholder Rights

Removing the Pass-Through Voting Provision from the HESI Charter would have no effect on the right of shareholders of the

Company to vote on matters relating to the Company, such as a merger or consolidation of the Company, a sale of all or

substantially all of the Company’s assets, or any other acts or transactions requiring the approval of the Company’s

shareholders under applicable law. If the proposed HESI Charter Amendment is approved by the Company’s shareholders

and effected, then the Pass-Through Voting Provision would be removed from the HESI Charter, and the Company would no

longer be required to obtain the additional approval of the Company’s shareholders for acts or transactions by or involving

HESI as is currently required by the Pass-Through Voting Provision.

Vote Required

The affirmative vote of the majority of the outstanding shares of our common stock entitled to vote on the matter is needed

to approve the proposal.

Proposal No. 5 Approval to Amend and

Restate the Halliburton Company Stock

and Incentive Plan

Introduction

The Halliburton Company Stock and Incentive Plan was last approved by shareholders at the 2024 Annual Meeting and

reserved 27,259,345 shares for issuance thereunder.

The proposed amendment and restatement of the Stock and Incentive Plan (Plan) replenishes the pool of shares of

Halliburton common stock available for issuance under the Stock and Incentive Plan by adding 19,900,000 shares and

makes minor language changes. The Stock and Incentive Plan is the only active plan used to grant awards of the types

described in this proposal.

Our Board is requesting that shareholders approve the amendment and restatement of the Stock and Incentive Plan, which

amendment and restatement was adopted by the Board on February 10, 2026, subject to shareholder approval.

General

In order to give Halliburton the flexibility to responsibly address its future equity compensation needs, Halliburton is

requesting that shareholders approve the amendment and restatement which adds 19,900,000 shares to the Plan.

The Plan contains the following important features:

• All awards under the Plan, with the exception of 5% of shares available for awards, are established with a one-year

minimum vesting period;

• The Plan contains a prohibition against “liberal share counting” or “liberal share recycling” with respect to shares available

for awards under the Plan;

• The Plan provides that all shares available for award are available for awards of incentive stock options;

• Repricing of stock options and stock appreciation rights is prohibited unless prior shareholder approval is obtained;

• Stock options and stock appreciation rights must be granted with an exercise price that is not less than 100% of the fair

market value on the date of grant;

• The ability to automatically receive replacement stock options when a stock option is exercised with previously acquired

shares of Halliburton common stock, or so-called “stock option reloading”, is not permitted;

• In any single calendar year, the value of awards granted under the Plan when added to any cash or other compensation

paid to a non-management Director outside of the Plan may not exceed $750,000;

• Awards are subject to clawback, recovery, or recoupment by Halliburton under any clawback or recoupment policy

adopted by Halliburton, whether before or after the date of grant of the award; and

• Awards are subject to “double-trigger” change of control vesting provisions.

The 19,900,000 shares to be added under the Plan pursuant to the amendment and restatement of the Plan, in combination

with the remaining authorized shares and shares added back into the Plan from forfeitures, are expected to satisfy

Halliburton’s equity compensation needs through the 2028 Annual Meeting of Shareholders. This being the case, if the

amendment and restatement is approved, Halliburton anticipates seeking the authorization of additional shares under the

Plan in 2028.

HALLIBURTON 2026 Proxy Statement 91

Share Reserve (adjusted for 1997 and 2006 stock splits where applicable)
Shares authorized under the Plan	284,024,680
Shares granted (less available cancellations and shares expired) from 1993 through March 1, 2026 from the Plan	271,417,850
Remaining shares available for grant as of March 1, 2026	12,606,830
Additional shares being requested under the amendment and restatement of the Plan	19,900,000
Total shares available for grant under the amended and restated Plan	32,506,830

(1) As of March 1, 2026 Halliburton, had total outstanding awards of options to purchase 6,925,222 shares with a weighted average

exercise price of $42.92 and a weighted average life of 1.76 years, full value awards with respect to 19,063,404 shares were

outstanding. As of the record date of March 23, 2026, there were 835,157,457 shares of our common stock outstanding.

(2) During 2025, Halliburton granted full value awards with respect to 6,951,867 shares, and 344,836 performance shares were earned.

As of December 31, 2025, our basic weighted average common shares outstanding was 852,939,319.

If the amendment and restatement of the Plan is approved by shareholders, the aggregate number of shares of Halliburton

common stock that will be available for issuance under the Plan would increas e to 32,506,830 sh ares, based on the

estimates set forth above, all of which shall be available for awards of incentive stock options. Each share issued as

restricted stock (or pursuant to the vesting of a stock unit or a performance share award) will count as the issuance of 1.60

shares reserved under the Plan, while each share granted as a stock option or stock appreciation right will count as the

issuance of 1.0 share reserved under the Plan. If awards granted under the Plan are forfeited or terminate before being

exercised, then the shares underlying those awards will again become available for awards under the Plan.

The Plan does not provide for “liberal share counting” or “liberal share recycling”. Liberal share counting or liberal share

recycling refers to circumstances where shares granted and exercised may be added back to an incentive plan for future

issuance, including the following situations:

• Shares tendered or withheld in payment of an exercise price;

• Shares tendered or withheld to satisfy tax withholding obligations;

• Shares reacquired by an issuer with the proceeds of an option exercise price; and

• Shares that are not issued due to a net settlement of an award.

In each of the situations above, such shares are no longer available for awards under the Plan. For example, shares

withheld from an award to satisfy tax withholding obligations are no longer available for awards under the Plan, and a stock

appreciation right or option will be counted in full against the number of shares available for issuance under the Plan,

regardless of whether a net settlement occurs resulting in a fewer number of shares issued than are covered by the stock

appreciation right or option.

The number of stock option shares or stock appreciation rights, singly or in combination, together with shares or share

equivalents under performance awards granted to any individual who is an employee in any one calendar year, shall not in

the aggregate exceed 1,000,000. The cash value determined as of the date of grant of any performance award not

denominated in common stock granted to any individual who is an employee for any one calendar year shall not exceed

$30,000,000. The value of awards (based on fair market value determined as of the date of grant) granted to a non-

management Director in any single calendar year, when added to any cash or other compensation payable to such Director

in the same calendar year, shall not exceed $750,000.

In the event of any recapitalization, reorganization, merger, consolidation, combination, exchange, stock dividend, stock

split, extraordinary dividend or divestiture (including a spin-off), or any other change in the corporate structure or shares of

common stock occurring after the date of the grant of an award, the Compensation Committee shall make appropriate

adjustments to the number and price of shares of common stock or other consideration subject to such awards and the

award limits set forth in the preceding paragraph.

The Stock and Incentive Plan

Types of Awards

The Plan provides for the grant of any or all of the following types of awards:

• stock options, including incentive stock options and nonqualified stock options;

• stock appreciation rights, either independent of, or in connection with, stock options;

• restricted stock;

• restricted stock units;

• performance awards; and

• stock value equivalent awards.

92 HALLIBURTON 2026 Proxy Statement www.halliburton.com

Term

The Plan has an indefinite term.

Any stock option granted in the form of an incentive stock option must satisfy the requirements of Section 422 of the Internal

Revenue Code (IRC). Awards may be made to the same person on more than one occasion and may be granted singly, in

combination, or in tandem as determined by the Compensation Committee. To date, only awards of nonqualified stock

options, restricted stock, restricted stock units, and performance awards have been made under the Plan.

Administration

The Board has appointed the Compensation Committee to administer the Plan. Subject to the terms of the Plan, and to any

approvals and other authority as the Board may reserve to itself from time to time, the Compensation Committee, consistent

with the terms of the Plan, will have authority to:

• select the individuals to receive awards and determine the timing, form, amount or value, and term of grants and awards,

including providing for terms regarding the accelerated vesting of an award otherwise subject to minimum vesting

provisions, and the conditions and restrictions, if any, subject to which grants and awards will be made and become

payable under the Plan;

• construe the Plan and prescribe rules and regulations for the administration of the Plan; and

• make any other determinations authorized under the Plan as the Compensation Committee deems necessary or

appropriate.

Eligibility

A broad group of our employees and employees of our affiliates are eligible to participate in the Plan. The selection of

participants from eligible employees is within the discretion of the Compensation Committee. Our non-management

Directors are eligible to participate in the Plan. As of January 1, 2026, approximate ly 5,8 00 emp loyees (including employees

and executive officers) and 11 non-management Directors were eligible for awards under the Plan as determined by the

Compensation Committee.

Stock Options

Under the Plan, the Compensation Committee may grant awards in the form of stock options to purchase shares of common

stock. The Compensation Committee will determine the number of shares subject to an option, the manner and time of the

option’s exercise, and the exercise price per share of stock subject to the option. Options are established with the first date

they may become vested and exercisable set to be at least one year from the date of grant, provided that up to 5% of the

shares available for grant under the Plan may be awarded without regard to the minimum one-year vesting period. The term

of an option may not exceed ten years. We do not receive any consideration for granting stock options. The exercise price of

a stock option will not be less than the fair market value of the common stock on the date the option is granted. Repricing of

stock options and reloading of stock options are prohibited unless prior shareholder approval is obtained. The Compensation

Committee will designate each option as a nonqualified or an incentive stock option.

The option exercise price may, at the discretion of the Compensation Committee, be paid by a participant in cash, shares of

common stock, or a combination of cash and common stock.

Stock Appreciation Rights

The Plan also authorizes the Compensation Committee to grant stock appreciation rights either independent of, or in

connection with, a stock option. The exercise price of a stock appreciation right will not be less than the fair market value of

the common stock on the date the stock appreciation right is granted. If granted with a stock option, exercise of stock

appreciation rights will result in the surrender of the right to purchase the shares under the option as to which the stock

appreciation rights were exercised. Upon exercising a stock appreciation right, the holder receives for each share for which

the stock appreciation right is exercised an amount equal to the difference between the exercise price and the fair market

value of the common stock on the date of exercise.

Payment of that amount may be made in shares of common stock, cash, or a combination of cash and common stock, as

determined by the Compensation Committee. Stock appreciation rights are established with the first date they may become

vested and exercisable set to be at least one year from the date of grant, provided that up to 5% of the shares available for

grant under the Plan may be awarded without regard to the minimum one-year vesting period. The term of a stock

appreciation right may not exceed ten years. Repricing of stock appreciation rights and reloading of stock appreciation rights

are prohibited unless prior shareholder approval is obtained. We do not receive any consideration for granting stock

appreciation rights.

HALLIBURTON 2026 Proxy Statement 93

Restricted Stock

The Plan provides that shares of common stock subject to specific restrictions may be awarded to eligible individuals as

determined by the Compensation Committee. The Compensation Committee will determine the nature and extent of the

restrictions on the shares, the duration of the restrictions, and any circumstance under which restricted shares will be

forfeited. The restriction period is established to be at least one year from the date of grant, provided that up to 5% of the

shares available for grant under the Plan may be awarded without regard to the minimum one-year vesting period. During

the period of restriction, recipients will have the right to receive dividends and the right to vote the shares.

Restricted Stock Units

The Plan authorizes the Compensation Committee to grant restricted stock units. A restricted stock unit is a unit evidencing

the right to receive one share of common stock or an equivalent cash value equal to the fair market value of a share of

common stock. The Compensation Committee will determine the nature and extent of the restrictions on the restricted stock

units, the duration of the restrictions, and any circumstance under which restricted stock units will be forfeited. The restriction

period is established to be at least one year from the date of grant, provided that up to 5% of the shares available for grant

under the Plan may be awarded without regard to the minimum one-year vesting period. The Compensation Committee may

provide for the payment of dividend equivalents during the period of restriction, but recipients will not have the right to

receive actual dividends or to vote the shares underlying the restricted stock units.

Performance Awards

The Plan permits the Compensation Committee to grant performance awards to eligible individuals. Performance awards

are awards that are contingent, in whole or in part, on the achievement of one or more performance measures. Performance

awards may be settled in cash or stock, as determined by the Compensation Committee. The number of shares or share

equivalents under performance awards, singly or in combination, together with the number of stock option shares or stock

appreciation rights, granted to any individual in any one calendar year, shall not in the aggregate exceed 1,000,000. The

cash value (determined as of the date of grant) of any performance award that is not denominated in stock granted to any

one participant in a calendar year may not exceed $30,000,000. The vesting period of a performance award may not be less

than one year from the date of grant, provided that up to 5% of the shares available for grant under the Plan may be

awarded without regard to the minimum one-year vesting period.

The performance criteria that may be used by the Compensation Committee in granting performance awards consist of

objective tests based on the following:

• earnings

• cash flow

• customer satisfaction

• revenues

• financial return ratios

• profit return and margins

• market share

• working capital

• net operating profit after-taxes

• asset turns

• cash value added performance

• return on capital

• shareholder return and/or value

• operating profits (including EBITDA)

• net profits

• earnings per share

• stock price

• cost reduction goals

• debt to capital ratio

• any other criteria as determined by the Compensation Committee

94 HALLIBURTON 2026 Proxy Statement www.halliburton.com

The Compensation Committee may select one criterion or multiple criteria for measuring performance. The measurement

may be based on our overall corporate performance, subsidiary or business unit performance, or comparative performance

with other companies or other external measures of selected performance criteria. The Compensation Committee will also

determine the length of time over which performance will be measured and the effect of a recipient’s death, disability,

retirement, or other termination of service during the performance period.

Stock Value Equivalent Awards

The Plan permits the Compensation Committee to grant stock value equivalent awards to eligible individuals. Stock value

equivalent awards are rights to receive the fair market value of a specified number of shares of common stock, or the

appreciation in the fair market value of the shares, over a specified period of time, pursuant to a vesting schedule, all as

determined by the Compensation Committee. Stock value equivalent awards are established with vesting dates at least one

year from the date of grant, provided that up to 5% of the shares available for grant under the Plan may be awarded without

regard to the minimum one-year vesting period. Payment of the vested portion of a stock value equivalent award shall be

made in cash, based on the fair market value of the common stock on the payment date.

Amendment

The Plan provides that the Board may at any time terminate or amend the Plan. However, the Board may not, without

approval of the shareholders, amend the Plan to effect a “material revision” of the Plan, where a “material revision” includes,

but is not limited to, a revision that:

• materially increases the benefits accruing to a participant under the Plan;

• materially increases the aggregate number of securities that may be issued under the Plan;

• materially modifies the requirements as to eligibility for participation in the Plan; or

• changes the types of awards available under the Plan.

No amendment or termination of the Plan shall, without the consent of the participant, alter or impair rights under any

awards previously granted.

The summary of the Plan provided above is a summary of the principal features of the Plan. This summary, however, does

not purport to be a complete description of all of the provisions of the Plan. It is qualified in its entirety by reference to the full

text of the Plan. A copy of the Plan can be found in Appendix B to this proxy statement.

Change-in-Control

Awards granted on or after February 13, 2019, are subject to double-trigger vesting, such that, if a participant is terminated

due to involuntary termination without cause, death, disability, good reason (as defined in an employment agreement, or a

similar constructive termination event, in each case, only if a severance benefit is payable upon termination of employment

due to such event pursuant to an employment agreement), or other event as specified in the participant’s award document

within the period beginning on the date of the public announcement of a transaction that, if consummated, would constitute a

corporate change and ending on the date that is the earlier of the announcement of the termination of the proposed

transaction or two years after the consummation of the transaction, the following will occur automatically:

• any outstanding options and stock appreciation rights shall become immediately vested and fully exercisable for the full

term thereof;

• any restrictions on restricted stock awards or restricted stock unit awards shall immediately lapse;

• all performance measures upon which an outstanding performance award is contingent shall be deemed achieved and the

holder shall receive a payment equal to the target amount of the award he or she would have been entitled to receive; and

• any outstanding cash awards, including stock value equivalent awards, shall immediately vest and be paid based on the

vested value of the award.

All awards granted prior to February 13, 2019, have vested and, as a result, all of our outstanding awards are subject to

double-trigger vesting provisions.

Plan Benefits

All awards to Directors, executive officers, and employees are made at the discretion of the Compensation Committee.

Therefore, the benefits and amounts that will be received or allocated under the Plan, as amended and restated, are not

determinable at this time.

HALLIBURTON 2026 Proxy Statement 95

Federal Income Tax Treatment

The following summarizes the current U.S. federal income tax consequences generally arising for awards under the Plan.

A participant who is granted an incentive stock option does not realize any taxable income at the time of the grant or at the

time of exercise, but in some circumstances may be subject to an alternative minimum tax as a result of the exercise.

Similarly, we are not entitled to any deduction at the time of grant or at the time of exercise. If the participant makes no

disposition of the shares acquired pursuant to an incentive stock option before the later of two years from the date of grant

and one year from the date of exercise, any gain or loss realized on a subsequent disposition of the shares will be treated as

a long-term capital gain or loss. Under these circumstances, we will not be entitled to any deduction for federal income tax

purposes. If the participant fails to hold the shares for that period, the disposal is treated as a disqualifying disposition. The

gain on the disqualifying disposition is ordinary income to the participant to the extent of the difference between the option

price and the fair market value on the exercise date. Any excess is long-term or short-term capital gain, depending on the

holding period. Under these circumstances, we will be entitled to a tax deduction equal to the ordinary income amount the

participant recognizes in a disqualifying disposition.

A participant who is granted a nonqualified stock option does not have taxable income at the time of grant, but does have

taxable income at the time of exercise. The income equals the difference between the exercise price of the shares and the

market value of the shares on the date of exercise. We are entitled to a corresponding tax deduction for the same amount.

The grant of a stock appreciation right will produce no U.S. federal tax consequences for the participant or us. The exercise

of a stock appreciation right results in taxable income to the participant, equal to the difference between the exercise price of

the shares and the market price of the shares on the date of exercise, and a corresponding tax deduction to us.

A participant who has been granted an award of restricted shares of common stock or an award of restricted stock units will

not realize taxable income at the time of the grant (unless, in the case of restricted shares, the participant makes an election

under IRC Section 83(b) within 30 days after the grant date to realize taxable income at the time of the grant based on the

fair market value of the shares on the grant date). When the restrictions lapse, the participant will recognize taxable income

in an amount equal to the excess of the fair market value of the shares or cash received at that time over the amount, if any,

paid for the shares. We will be entitled to a corresponding tax deduction. Dividends on restricted stock and dividend

equivalents, if any, on restricted stock units paid to the participant during the restriction period will also be compensation

income to the participant and will be deductible as compensation expense by us (unless, in the case of restricted shares, the

participant makes an election under IRC Section 83(b) within 30 days after the grant date).

A participant who has been granted a performance award will not realize taxable income at the time of the grant, and we will

not be entitled to a tax deduction at that time. A participant will realize ordinary income at the time the award is paid equal to

the amount of cash paid or the value of shares delivered, and we will be entitled to a corresponding tax deduction.

The grant of a stock value equivalent award produces no U.S. federal income tax consequences for the participant or us.

The payment of a stock value equivalent award results in taxable income to the participant equal to the amount of the

payment received, valued with reference to the fair market value of the common stock on the payment date. We are entitled

to a corresponding tax deduction for the same amount.

In order for Halliburton to deduct the amounts described above, such amounts must constitute reasonable compensation for

services rendered or to be rendered and must be ordinary and necessary business expenses. The ability to obtain a

deduction for awards under the Plan could also be limited by IRC Section 280G, which provides that certain excess

parachute payments made in connection with a change in control of an employer are not deductible. The ability to obtain a

deduction for amounts paid under the Plan could also be affected by IRC Section 162(m), which limits the deductibility, for

U.S. federal income tax purposes, of compensation paid to certain employees to $1 million during any taxable year. As a

result, we may from time to time in the future make award payments under the Plan to executive officers that are not

deductible.

We may withhold any taxes required by law to be withheld in connection with any award.

IRC Section 409A generally provides that any deferred compensation arrangement which does not meet specific

requirements regarding (i) timing of payouts, (ii) advance election of deferrals, or (iii) restrictions on acceleration of payouts

will result in immediate taxation of any amounts deferred to the extent not subject to a substantial risk of forfeiture. Failure to

comply with Section 409A may result in the early taxation (plus interest) to the holder of deferred compensation and the

imposition of a 20% penalty tax on the holder on such deferred amounts included in the holder’s income. In general, to avoid

a Section 409A violation, amounts deferred may only be paid out on separation from service, disability, death, a change-in-

control, an unforeseen emergency (other than death), each as defined under Section 409A, or at a specified time.

Furthermore, the election to defer generally must be made in the calendar year prior to performance of services, and any

provision for accelerated payout, other than for the reasons specified above, may cause the amounts deferred to be subject

to early taxation and to the imposition of the excise tax. Based on current guidance, we intend to structure future awards in a

manner that is exempt from or complies with Section 409A.

HALLIBURTON 2026 Proxy Statement 97

Proposal No. 6 Approval to Amend and

Restate the Halliburton Company

Employee Stock Purchase Plan

Introduction

In 2002, the Board of Directors adopted and the shareholders approved the Halliburton Company 2002 Employee Stock

Purchase Plan (2002 ESPP), effective July 1, 2002, and reserved 24,000,000 shares (as adjusted for a 2-1 stock split in July

2006) for issuance under the 2002 ESPP. The 2002 Non-Qualified Stock Purchase Plan, a sub-plan of the 2002 ESPP (Sub-

Plan), was established to facilitate the offering of stock ownership interests to employees residing outside the United States.

In 2009, the 2002 ESPP was renamed the Halliburton Company Employee Stock Purchase Plan (ESPP), the Sub-Plan was

renamed the Halliburton Company Non-Qualified Stock Purchase Plan (NQSPP) and an additional 20,000,000 shares were

approved by shareholders for issuance under the plans. In 2015 and 2021, the ESPP was amended and restated, and

shareholders approved an additional 30,000,000 shares each such year for issuance under the plans .

This amendment and restatement replenishes the pool of shares of Halliburton common stock available for purchase under

the ESPP by adding 30,000,000 shares. This amended and restated ESPP is subject to shareholder approval.

Our Board is requesting that shareholders approve the amendment and restatement of the ESPP and the reservation of

shares for issuance under the ESPP, which amendment and restatement was approved by the Board of Directors on

February 10, 2026. Shareholder approval will qualify the shares for special tax treatment under IRC Section 423 .

General

The purpose of the ESPP is to provide employees of Halliburton and its designated subsidiaries with the opportunity to

purchase Halliburton common stock and, therefore, to have an additional incentive to contribute to the prosperity of

Halliburton.

The Employee Stock Purchase Plan

Administration

The ESPP is administered by the Compensation Committee. None of the members of the Compensation Committee is an

officer or employee, or former officer or employee, of Halliburton or its subsidiaries. Subject to the terms of the ESPP, the

Compensation Committee has the power to make, amend, and repeal rules and regulations for the interpretation and

administration of the ESPP. The decisions of the Compensation Committee are final and binding upon all parties.

Shares Subject to the ESPP

As amended and restated, there will be a total of 134,000,000 shares authorized under the ESPP, subject to adjustment as

described below. The reserved shares will also be used to fund stock purchases under the NQSPP, and any shares issued

under the NQSPP will reduce, on a share-for-share basis, the number of shares available for subsequent issuance under

the ESPP.

Eligibility

In general, any employee of Halliburton or a designated subsidiary is eligible to participate in the ESPP during a purchase

period unless the employee is employed in a country whose laws or regulations effectively prohibit participation in the plan. A

“purchase period” is a period of approximately three months that begins on the first trading day of each January, April, July,

and October. An “enrollment date” is the first day of each purchase period. Eligible employees become participants in the

ESPP by filing with Halliburton a payroll deduction authorization form within the time prescribed by the Compensation

Committee prior to an enrollment date.

As of January 31, 2026 , 84,697,071 shares of common stock had been issued under the ESPP and the NQSPP, and

49,302,939 shares would be available for future issuance, assuming approval of the 30,000,000 share increase, which forms

part of this proposal. As of January 31, 2026, approximately 40,000 employees, including 10 executive officers, were eligible

to participate in the ESPP.

98 HALLIBURTON 2026 Proxy Statement www.halliburton.com

Participation

Each participant is granted a right to purchase shares of Halliburton common stock on his or her enrollment date. A

participant in the ESPP may make contributions through payroll deductions of up to 10% of his or her eligible compensation

each pay period, but not less than $10 for any pay period. Stock purchase rights may not accrue at a rate that exceeds

$25,000 in fair market value of the common stock (determined at the time such stock purchase rights are granted) per

calendar year. The participant’s contributions are used to purchase shares of Halliburton’s common stock at the end of each

purchase period. The right to purchase Halliburton shares is exercised automatically on the last trading day of each

purchase period (purchase date) to the extent of the payroll deductions accumulated during the purchase period, provided

that the number of shares that may be purchased by a participant in any purchase period is limited to 10,000 shares. No

participant shall be granted a stock purchase right under the ESPP to the extent that, immediately after the grant, such

participant (or any other person whose stock would be attributed to such participant) would own capital stock of Halliburton

and/or hold outstanding options to purchase such stock possessing 5% or more of the total combined voting power or value

of all classes of the capital stock of Halliburton or any of its subsidiaries.

The purchase price per share is equal to 90% of the fair market value of the common stock on the enrollment date or the

purchase date, whichever is lower. The number of whole and fractional shares of Halliburton common stock a participant

purchases in each purchase period is determined by dividing the total amount of payroll deductions during the purchase

period by the purchase price.

Termination of Employment

Termination of a participant’s employment for any reason, including death, immediately cancels his or her participation in the

ESPP. In that event, the payroll deductions credited to the participant’s account will be refunded to him or her, and in the

case of death, to his or her estate or personal representative.

Changes in Common Stock; Adjustments

In the event that Halliburton’s common stock is changed by reason of any stock split, stock dividend, recapitalization,

combination, or other similar change in Halliburton’s capital structure, appropriate action will be taken by the Compensation

Committee to adjust any or all of (i) the number and type of shares subject to the ESPP, (ii) the number and type of shares

subject to outstanding stock purchase rights, and (iii) the purchase price. In the event of a Corporate Change (as defined in

the ESPP), unless the successor corporation assumes or substitutes new stock purchase rights:

• the purchase date for the outstanding stock purchase rights will be accelerated to a date fixed by the Compensation

Committee prior to the effective date of the Corporate Change; and

• on the effective date, any unexercised stock purchase rights will expire and Halliburton will promptly refund the unused

amount of each participant’s payroll deductions.

Amendment and Termination of the Plan

The Board may terminate the ESPP at any time with respect to common stock that is not subject to stock purchase rights.

The Board may amend the ESPP at any time, provided that no change may be made in any outstanding stock purchase

right that would materially impair that right without the consent of the participant. If not sooner terminated, the ESPP will

automatically terminate when all of the shares of common stock reserved for issuance have been sold.

Withdrawal

Generally, a participant may withdraw from the ESPP during a purchase period at any time prior to the fifth business day

before a purchase date.

The summary of the ESPP provided above is a summary of the principal features of the plan. This summary, however, does

not purport to be a complete description of all of the provisions of the ESPP. It is qualified in its entirety by reference to the

full text of the ESPP. A copy of the ESPP can be found in Appendix C to this proxy statement, and any shareholder who

wishes to obtain a copy of the ESPP may do so by written request to the Corporate Secretary at the address set forth on

page 10 0 of this proxy statement.

Plan Benefits

The benefits to be received by Halliburton’s executive officers and employees as a result of the proposed amendment and

restatement of the ESPP are not determinable, since the amounts of future purchases by participants are based on elective

participant contributions. Non-employee Directors are not eligible to participate. No purchase rights have been granted, and

HALLIBURTON 2026 Proxy Statement 99

no shares of common stock have been issued, with respect to the 30,000,000 share increase for which shareholder

approval is sought under this proposal.

U.S. Federal Income Tax Treatment

The following summarizes the effect of current U.S. federal income tax upon the participant and Halliburton with respect to

shares purchased under the ESPP. It does not purport to be complete, and does not discuss the tax consequences arising in

the context of a participant’s death or the income tax laws of any municipality, state, or foreign country in which the

participant’s income or gain may be taxable.

If the Halliburton shareholders approve this proposal, the ESPP, and the right of participants to make purchases thereunder,

should qualify under the provisions of Sections 421 and 423 of the IRC. Under these provisions, no income will be taxable to

a participant until the shares purchased under the ESPP are sold or otherwise disposed of. Upon sale or other disposition of

the shares, the participant will generally be subject to tax and the amount of the tax will depend on the holding period. If the

shares are sold or disposed of more than two years from the first day of the applicable purchase period and more than one

year from the date of transfer of the shares to the participant, then the participant generally will recognize ordinary income

measured as the lesser of:

• the excess of the fair market value of the shares at the time of sale over the purchase price, or

• 10% of the fair market value of the shares as of the enrollment date.

Any additional gain should be treated as long-term capital gain. If the shares are disposed of within the two-year and one-

year periods referred to above, the participant will recognize ordinary income generally measured as the difference between

the fair market value of the shares on the purchase date over the purchase price. Any additional gain or loss on the sale will

be long-term or short-term capital gain or loss, depending on the holding period. Halliburton is not entitled to a deduction for

amounts taxed as ordinary income or capital gain to a participant except to the extent ordinary income is recognized by

participants upon a disposition of shares prior to the expiration of the holding period.

Non-U.S. Federal Income Tax Treatment

The income taxation consequences to participants and Halliburton (or its foreign subsidiaries) with respect to participation in

the NQSPP vary by country. Generally, participants are subject to taxation at the time of purchase. The employing foreign

subsidiary may be entitled to a deduction in the tax year in which a participant recognizes taxable income, provided the

subsidiary reimburses Halliburton for the cost of the benefit conferred under the NQSPP.

General/Vote Required

The closing price of our common stock on March 23, 2026, as traded on the NYSE, was $37.51 per share.

The affirmative vote of the majority of the votes cast by holders of shares of our common stock present in person or

represented by proxy at the meeting and entitled to vote on the subject matter is needed to approve the proposal.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE APPROVAL OF THE PROPOSED AMENDMENT AND RESTATEMENT OF THE HALLIBURTON COMPANY EMPLOYEE STOCK PURCHASE PLAN.

statement only if you have requested that a copy of this proxy statement be mailed to you. The Annual Report on Form 10-K

is also available electronically by following the instructions in the Notice of Internet Availability of Proxy Materials. The Annual

Report on Form 10-K shall not be considered as a part of the proxy solicitation materials or as having been incorporated by

reference.

We will furnish without charge to each person whose proxy is being solicited, upon the written request of any such

person, a copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, including the

financial statements. Such requests should be directed to the Corporate Secretary, Halliburton Company, 3000 N.

Sam Houston Parkway East, Houston, Texas 77032.

Subject to space availability, all shareholders as of the record date, or their duly appointed proxies, may attend the Annual

Meeting and each may be accompanied by one guest. Admission to the Annual Meeting will be on a first-come, first-served

basis. Registration will begin at 8:00 a.m. and the Annual Meeting will begin at 9:00 a.m. Please note that we will ask you to

present valid picture identification, such as a driver’s license or passport, when you check in at the registration desk.

If you hold your shares in “street name” (that is, through a broker or other nominee), you must bring a proxy issued in your

name from the record holder to the meeting.

You may not bring cameras, recording equipment, electronic devices, bags, briefcases, or packages into the

Annual Meeting.

If you attend the Annual Meeting, you may vote in person. If you are not present, you can only vote your shares if you have

voted via the Internet or by telephone or returned a properly executed proxy pursuant to the instructions set forth on the

Notice of Internet Availability of Proxy Materials; in these cases, your shares will be voted as you specified. If you return a

properly executed proxy and do not specify a vote, your shares will be voted in accordance with the recommendations of the

Board.

You may revoke the authorization given in your proxy at any time before the shares are voted at the Annual Meeting by

attending the Annual Meeting and voting those shares in person, by submitting a properly executed proxy bearing a later

date, or by delivering written notice of revocation to the Corporate Secretary at the address set forth above. If you hold your

shares in “street name”, you must follow the procedures of your broker or other nominee to change your voting instructions.

The record date for determination of the shareholders entitled to vote at the Annual Meeting is the close of business on

March 23, 2026 . Our common stock, par value $2.50 per share, is our only class of capital stock that is outstanding. As of

March 23, 2026 , there were 835,157,457 shares of our common stock outstanding. Each outstanding share of common

stock is entitled to one vote on each matter submitted to the shareholders for a vote at the Annual Meeting. We will maintain

for a period of ten days ending on the day before the meeting date at our principal executive office a complete list of

shareholders entitled to vote at the Annual Meeting, which list shall be open to the examination of any shareholder for any

purpose germane to the meeting during ordinary business hours. Our principal executive office is located at 3000 N. Sam

Houston Parkway East, Administration Building, Houston, Texas 77032.

Votes cast by proxy or in person at the Annual Meeting will be counted by the persons we appoint to act as election

inspectors for the Annual Meeting. The holders of a majority in voting power of the issued and outstanding shares of our

common stock present in person or represented by proxy and entitled to vote at the Annual Meeting shall constitute a

quorum for the transaction of business at such meeting. The election inspectors will treat broker non-votes, which are shares

held in street name that cannot be voted by a broker on specific matters in the absence of instructions from the beneficial

owner of the shares, as shares that are present and entitled to vote for purposes of determining the presence of a quorum.

Brokers holding shares must vote according to specific instructions they receive from the beneficial owners of those shares.

If brokers do not receive specific instructions from the beneficial owner, NYSE rules govern whether or not the broker is

permitted to vote on the beneficial owner’s behalf. The NYSE has designated certain categories of proposals as “ routine”,

and, in the absence of specific instructions from the beneficial owner, brokers are permitted to vote on routine matters at

their discretion. However, in the absence of specific instructions from the beneficial owner, brokers are prohibited from voting

on any matter deemed non-routine, which results in a broker non-vote for such proposal.

which we mail the Notice of Internet Availability of Proxy Materials to shareholders for the Annual Meeting, the Directors shall be elected by

Appreciation Right, such Fair Market Value shall be the prevailing price of the Common Stock as of the time of

exercise. If the Common Stock is not then listed or quoted on any national securities exchange but is traded over the

counter at the time a determination of its Fair Market Value is required to be made hereunder, its Fair Market Value

shall be deemed to be equal to the average between the reported high and low sales prices of Common Stock on the

expired by reason of lapse of time, all restrictions imposed upon Restricted Stock Awards and Restricted Stock Unit Awards

have lapsed and all Performance Awards and Stock Value Equivalent Awards have been satisfied.

IV. Administration

(a) Composition of Committee. The Plan shall be administered by a Committee of Directors of the Company which shall

be appointed by the Board.

(b) Powers. The Committee shall have authority, in its discretion, to determine which eligible individuals shall receive an

Award, the time or times when such Award shall be made, whether an Incentive Stock Option, nonqualified Option or

Stock Appreciation Right shall be granted, the number of shares of Common Stock which may be issued under each

Option, Stock Appreciation Right, Restricted Stock Award and Restricted Stock Unit Award, and the value of each

Performance Award and Stock Value Equivalent Award. The Committee shall have the authority, in its discretion, to

establish the terms and conditions applicable to any Award, subject to any specific limitations or provisions of the Plan.

In making such determinations the Committee may take into account the nature of the services rendered by the

respective individuals, their responsibility level, their present and potential contribution to the Company’s success and

such other factors as the Committee in its discretion shall deem relevant. Notwithstanding any provision of the Plan to

the contrary, the Committee may provide for the acceleration of vesting or exercisability of an Award upon a Corporate

Change, upon a termination of employment or service by reason of death, disability, retirement or otherwise or for any

other reason.

(c) Additional Powers. The Committee shall have such additional powers as are delegated to it by the other provisions of

the Plan. Subject to the express provisions of the Plan, the Committee is authorized to construe the Plan and the

respective Award Documents executed thereunder, to prescribe such rules and regulations relating to the Plan as it

may deem advisable to carry out the Plan, and to determine the terms, restrictions and provisions of each Award,

including such terms, restrictions and provisions as shall be requisite in the judgment of the Committee to cause

designated Options to qualify as Incentive Stock Options, and to make all other determinations necessary or advisable

for administering the Plan. The Committee may correct any defect or supply any omission or reconcile any

inconsistency in any Award Document relating to an Award in the manner and to the extent the Committee shall deem

expedient to carry the Award into effect. The determinations of the Committee on the matters referred to in this Article

IV shall be conclusive.

(d) Delegation of Authority. The Committee may delegate some or all of its power to the Chief Executive Officer of the

Company as the Committee deems appropriate; provided, however, that the Committee may not delegate its power

with regard to the selection for participation in the Plan of an officer or other person subject to Section 16 of the

Exchange Act or decisions concerning the timing, pricing or amount of an Award to such an officer or other person and

any delegation of the power to grant Awards shall be permitted by applicable law.

(e) Engagement of an Agent. The Company may, in its discretion, engage an agent to (i) maintain records of Awards and

Holders’ holdings under the Plan, (ii) execute sales transactions in shares of Common Stock at the direction of

Holders, (iii) deliver sales proceeds as directed by Holders, and (iv) hold shares of Common Stock owned without

have no obligation to provide any further services to such person and the shares of Common Stock previously held by

the agent under the Plan may be distributed to the person or his or her legal representative.

Awards, Performance Awards and Stock Value Equivalent Awards; Shares Subject to the Plan

eligible for participation in the Plan in accordance with the provisions of Article VI. The aggregate number of shares of

Common Stock that may be issued under the Plan shall not exceed 32,506,830 shares , all of which shall be available

for Awards of Incentive Stock Options. Shares issued as Restricted Stock Awards, Restricted Stock Unit Awards or

pursuant to Performance Awards will count against the shares available for issuance under the Plan as 1.60 shares for

every 1 share issued in connection with the Award. Notwithstanding anything contained herein to the contrary, the

HALLIBURTON 2026 Proxy Statement B-5

number of Option shares or Stock Appreciation Rights, singly or in combination, together with shares or share

equivalents under Performance Awards granted to any Holder who is an employee in any one calendar year, shall not

in the aggregate exceed 1,000,000. The cash value determined as of the date of grant of any Performance Award not

denominated in Common Stock granted to any Holder who is an employee in any one calendar year shall not exceed

$30,000,000. The fair market value, determined as of the date of grant, of Awards granted to a Holder who is a non-

management Director in any one calendar year, when added to any cash or other compensation payable to such a

Holder in such calendar year, shall not exceed $750,000. Any shares which remain unissued and which are not subject

to outstanding Options or Awards at the termination of the Plan shall cease to be subject to the Plan, but, until

termination of the Plan, the Company shall at all times reserve a sufficient number of shares to meet the requirements

of the Plan. If Awards are forfeited or are terminated for any other reason before being exercised or settled, then the

shares underlying such Awards shall again become available for Awards under the Plan. Notwithstanding the

foregoing, the following shares shall not become available for Awards under the Plan: (i) shares tendered by an

Optionee or withheld by the Company for payment of an option price, (ii) shares tendered by a Holder or withheld by

the Company to satisfy the Company’s tax withholding obligation in connection with an Award, (iii) shares reacquired in

the open market or otherwise using cash proceeds from the exercise of Options, and (iv) shares that are not issued to

a Holder due to a net settlement of an Award. For purposes of clarity, Stock Appreciation Rights and Options shall be

counted in full against the number of shares available for issuance under the Plan, regardless of the number of shares

issued upon settlement of the Stock Appreciation Rights and Options. The shares underlying a Restricted Stock Award

to the extent vested shall not again become available for Awards under the Plan. The aggregate number of shares

which may be issued under the Plan shall be subject to adjustment in the same manner as provided in Article XIII with

respect to shares of Common Stock subject to Options then outstanding. The 1,000,000-share limit on Holders who

are employees with respect to Stock Options and Stock Appreciation Rights Awards, singly or in combination, together

with shares or share equivalents under Performance Awards granted to any Holder who is an employee in any

calendar year shall be subject to adjustment in the same manner as provided in Article XIII. Separate stock certificates

shall be issued by the Company for those shares acquired pursuant to the exercise of an Incentive Stock Option and

for those shares acquired pursuant to the exercise of any Option which does not constitute an Incentive Stock Option.

(b) Stock Offered. The stock to be offered pursuant to the grant of an Award may be authorized but unissued Common

Stock or Common Stock previously issued and reacquired by the Company.

VI. Eligibility

evidenced in such manner and form as may be prescribed by the Committee.

Optionee which shall contain such terms and conditions as may be approved by the Committee. The terms and

conditions of the respective Option Agreements need not be identical. Specifically, an Option Agreement may provide

for the payment of the option price, in whole or in part, by the delivery of a number of shares of Common Stock (plus

cash if necessary) having a Fair Market Value equal to such option price.

applicable to an Option; provided, however, that such Restriction Period shall not be less than the Minimum Criteria.

Notwithstanding the foregoing, Awards of Options may utilize the Minimum Criteria Exception.

as determined by the Committee.

date the Option is granted.

Appreciation Rights may be granted under the Plan from time to time in substitution for stock options held by

employees of corporations who become, or who became prior to the effective date of the Plan, employees of the

Company or of any Subsidiary as a result of a merger or consolidation of the employing corporation with the Company

or such Subsidiary, or the acquisition by the Company or a Subsidiary of all or a portion of the assets of the employing

corporation, or the acquisition by the Company or a Subsidiary of stock of the employing corporation with the result

that such employing corporation becomes a Subsidiary.

(g) Repricing Prohibited. Except for adjustments pursuant to Article XIII, the purchase price of Common Stock for any

outstanding Option granted under the Plan may not be decreased after the date of grant nor may an outstanding

Option granted under the Plan be surrendered to the Company as consideration for the grant of a new Option with a

B-6 HALLIBURTON 2026 Proxy Statement www.halliburton.com

respect to a share of Common Stock upon the exercise of such Stock Appreciation Right. Stock Appreciation Rights

may be granted in connection with the grant of an Option, in which case the Option Agreement will provide that

exercise of Stock Appreciation Rights will result in the surrender of the right to purchase the shares under the Option

as to which the Stock Appreciation Rights were exercised. Alternatively, Stock Appreciation Rights may be granted

independently of Options in which case each Award of Stock Appreciation Rights shall be evidenced by a Stock

Appreciation Rights Agreement between the Company and the Holder which shall contain such terms and conditions

as may be approved by the Committee. The terms and conditions of the respective Stock Appreciation Rights

Agreements need not be identical. The Spread with respect to a Stock Appreciation Right may be payable either in

cash, shares of Common Stock with a Fair Market Value equal to the Spread or in a combination of cash and shares of

Common Stock as determined by the Committee in its sole discretion.

such installments and at such times as determined by the Committee.

be surrendered to the Company as consideration for the grant of a new Stock Appreciation Right with a lower exercise

price, cash or a new Award unless there is prior approval by the Company stockholders. Any other action that is

deemed to be a repricing under any applicable rule of the New York Stock Exchange shall be prohibited unless there is

prior approval by the Company stockholders.

pursuant to a Restricted Stock Award, except to the extent otherwise required by law and except that the Committee

may, in its discretion, charge the Holder an amount in cash not in excess of the par value of the shares of Common

Stock issued under the Plan to the Holder.

(d) Miscellaneous. Nothing in this Article shall prohibit the exchange of shares issued under the Plan (whether or not then

subject to a Restricted Stock Award) pursuant to a plan of reorganization for stock or securities in the Company or

another corporation a party to the reorganization, but the stock or securities so received for shares then subject to the

restrictions of a Restricted Stock Award shall become subject to the restrictions of such Restricted Stock Award. Any

shares of stock received as a result of a stock split or stock dividend with respect to shares then subject to a Restricted

or the acquisition by the Company or a Subsidiary of all or a portion of the assets of the employing corporation, or the

discretion. Payment of a Performance Award (i) may be made in cash, Common Stock or a combination thereof, as

the Committee in its sole discretion, and (iii) to the extent applicable, shall be based on the Fair Market Value of the

Common Stock on the payment date.

of its assets or business or any other corporate act or proceeding.

(c) The shares with respect to which Options, Stock Appreciation Rights or Restricted Stock Units may be granted are

granted, the purchase price per share of Common Stock subject to Options or the calculation of the Spread with

(d) Other Laws; Withholding. The Company shall not be obligated to issue any shares of Common Stock pursuant to

any Award at any time, when the offering of the shares of Common Stock covered by such Award has not been

registered under the U.S. Securities Act of 1933, as amended (the “Act”) or such other country, U.S. federal or state

laws, rules or regulations as the Company deems applicable and, in the opinion of legal counsel for the Company,

there is no exemption from the registration. The Company intends to use reasonable efforts to ensure that no such

delay will occur. In the event exemption from registration under the Act is available upon vesting of an Award, the

Participant, if requested by the Company to do so, will execute and deliver to the Company in writing an agreement

containing such provisions as the Company may require to assure compliance with applicable securities laws. By

accepting an Award, the Participant agrees that the shares of Common Stock which the Participant may acquire upon

vesting of an Award will not be sold or otherwise disposed of in any manner which would constitute a violation of any

applicable U.S. federal, state or non-U.S. securities laws. Furthermore, the Participant also agrees (i) that the

Company may refuse to register the transfer of the shares of Common Stock acquired under an Award on the stock

transfer records of the Company if such proposed transfer would in the opinion of counsel to the Company constitute a

violation of any applicable securities law, and (ii) that the Company may give related instructions to its transfer agent, if

any, to stop registration of the transfer of the shares of Common Stock acquired under the Plan. No fractional shares of

Common Stock shall be delivered, nor shall any cash in lieu of fractional shares be paid. The Company shall have the

right to deduct in connection with all Awards any taxes required by law to be withheld and to require any payments

necessary to enable it to satisfy its withholding obligations. The Committee may permit the Holder of an Award to elect

to surrender, or authorize the Company to withhold, shares of Common Stock (valued at their Fair Market Value on the

date of surrender or withholding of such shares) in satisfaction of the Company’s withholding obligation, subject to

such restrictions as the Committee deems appropriate.

(e) No Restriction on Corporate Action. Nothing contained in the Plan shall be construed to prevent the Company or

any Subsidiary from taking any corporate action which is deemed by the Company or such Subsidiary to be

appropriate or in its best interest, whether or not such action would have an adverse effect on the Plan or any Award

made under the Plan. No Holder, beneficiary or other person shall have any claim against the Company or any

Subsidiary as a result of any such action.

(f) Restrictions on Transfer. No Award may be sold, assigned, pledged, exchanged, hypothecated, encumbered,

disposed of, or otherwise transferred, except by will or the laws of descent and distribution or pursuant to a “qualified

domestic relations order” as defined by the Code or Title I of the U.S. Employee Retirement Income Security Act of

1974, as amended, or similar order. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of

an Award or of such rights contrary to the provisions of an Award Document or in the Plan, the Award and such rights

shall immediately become null and void. The Committee may prescribe and include in the respective Award

Documents hereunder other restrictions on transfer. Upon a Holder’s death, the Holder’s personal representative or

other person entitled to succeed to the rights of the Holder (the “Successor Holder”) may exercise such rights as are

provided under the applicable Award Document. A Successor Holder must furnish proof satisfactory to the Company of

his or her rights to exercise the Award under the Holder’s will or under the applicable laws of descent and distribution.

Notwithstanding the foregoing, the Committee shall have the authority, in its discretion, to grant (or to sanction by way

B-10 HALLIBURTON 2026 Proxy Statement www.halliburton.com

of amendment to an existing grant) Awards (other than Incentive Stock Options) which may be transferred by the

Holder for no consideration to or for the benefit of the Holder’s Immediate Family, to a trust solely for the benefit of the

Holder and his Immediate Family, or to a partnership or limited liability company in which the Holder and members of

his Immediate Family have at least 99% of the equity, profit and loss interest, in which case the Award Document shall

so state. A transfer of an Award pursuant to this Paragraph (f) shall be subject to such rules and procedures as the

Committee may establish. In the event an Award is transferred as contemplated in this Paragraph (f), such Award may

not be subsequently transferred by the transferee except by will or the laws of descent and distribution, and such

Award shall continue to be governed by and subject to the terms and limitations of the Plan and the relevant written

instrument for the Award and the transferee shall be entitled to the same rights as the Holder under Articles XIII and

XIV hereof as if no transfer had taken place. No transfer shall be effective unless and until written notice of such

transfer is provided to the Committee, in the form and manner prescribed by the Committee. The consequences of

termination of employment shall continue to be applied with respect to the original Holder, following which the Awards

shall be exercised by the transferee only to the extent and for the periods specified in the Plan and the related Award

Document. The Option Agreement, Stock Appreciation Rights Agreement, Restricted Stock Award Agreement,

Restricted Stock Unit Award Agreement or other Award Document shall specify the effect of the death of the Holder on

the Award.

(g) Governing Law . This Plan shall be construed in accordance with the laws of the State of Texas, except to the extent

that it implicates matters which are the subject of the General Corporation Law of the State of Delaware which matters

shall be governed by the latter law.

(h) Foreign Awardees. Without amending the Plan, the Committee may grant Awards to eligible persons who are foreign

nationals on such terms and conditions different from those specified in the Plan as may, in the judgment of the

Committee, be necessary or desirable to foster and promote achievement of the purposes of the Plan and, in

furtherance of such purposes, the Committee may make such modifications, amendments, procedures, subplans and

the like as may be necessary or advisable to comply with the provisions of laws and regulations in other countries or

jurisdictions in which the Company or its Subsidiaries operate.

(i) Clawback or Recoupmen t. Notwithstanding any other provisions in this Plan, any Award shall be subject to clawback,

recovery or recoupment by the Company under any clawback or recoupment policy adopted by the Company, whether

before or after the date of grant of the Award.

the Plan may be modified as applied to the Participating Company only to the extent permitted under Section 423 of the

employment hereunder. Any Participating Company may, by appropriate action of its Board of Directors, terminate its

participation in the Plan. Moreover, the Committee may, in its discretion, terminate a Participating Company’s Plan

participation in the Plan at any time.

5. Eligibility. Subject to the further provisions hereof, all Eligible Employees as of an Enrollment Date shall be eligible to

participate in the Plan with respect to the Purchase Period beginning as of such date.

6. Stock Subject to the Plan. Subject to the provisions of paragraph 13, the aggregate number of shares of Stock

which may be sold under the Plan and the Sub-Plan shall not exceed 134,000,000 shares, which shares may be authorized

but unissued shares or treasury shares, including shares bought on the open market or otherwise for purposes of the Plan.

7. Stock Purchase Rights.

(a) Grant of Stock Purchase Rights. On each Enrollment Date the Company shall grant a stock purchase right to each

Eligible Employee who elects to participate in the Plan for the Purchase Period beginning on such date. Subject to

subparagraphs 7(f) and (g), the number of shares of Stock subject to a stock purchase right for a participant shall be equal

to the quotient of (i) the aggregate payroll deductions withheld on behalf of such participant during the Purchase Period,

divided by (ii) the Purchase Price of the Stock applicable to the Purchase Period; provided, however, that the maximum

number of shares of Stock that may be subject to any stock purchase right for a participant during any Purchase Period may

not exceed 10,000 shares (subject to adjustment as provided in paragraph 13). Whole and fractional shares shall be

purchased, unless the Committee determines that the purchase of fractional shares is administratively impracticable. Any

references in the Plan to “shares” shall include fractional shares, if any, purchased by the participant under the Plan.

(b) Election to Participate; Payroll Deduction Authorization. An Eligible Employee may participate in the Plan only by

means of payroll deduction. Except as provided in subparagraph 7(f), each Eligible Employee who elects to participate in the

Plan shall deliver to the Company, within the time period prescribed by the Committee, a payroll deduction authorization in

the form or manner prescribed by the Company, whereby he gives notice of his election to participate in the Plan as of the

HALLIBURTON 2026 Proxy Statement C-3

next following Enrollment Date, and whereby he designates an integral percentage (except as provided below) to be

deducted from his Eligible Compensation for each pay period paid during the Purchase Period and paid into the Plan for his

account. The designated percentage may not exceed 10%; provided, however, the minimum contribution per pay period

shall be $10.

(c) Changes in Payroll Authorization. All payroll deductions made for a participant shall be credited to his account

under the Plan. A participant may discontinue his participation in the Plan as provided in paragraph 9 hereof, or may

increase or decrease the rate of his payroll deductions during the Purchase Period by completing or filing with the Company,

at a time and in a manner prescribed by the Committee, a new payroll deduction authorization form authorizing a change in

his payroll rate. The Committee may, in its discretion, limit the number of payroll rate changes during any Purchase Period.

The change in rate shall be effective as soon as administratively practicable after the Company’s receipt of the new payroll

deduction authorization form. A participant’s payroll deduction authorization form shall remain in effect for successive

Purchase Periods unless terminated as provided in paragraph 9 hereof.

(d) Automatic Payroll Reduction. Notwithstanding the foregoing, to the extent necessary to comply with subparagraphs

7(f) and (g) hereof, a participant’s payroll deductions may be decreased to 0% at any time during a Purchase Period. Payroll

deductions shall recommence at the rate provided in such participant’s payroll deduction authorization form at the beginning

of the first Purchase Period that is scheduled to end in the following calendar year, unless terminated by the participant as

provided in paragraph 9 hereof.

(e) Tax Withholding. At the time the stock purchase right is exercised, in whole or in part, or at the time some or all of

the Stock issued under the Plan is disposed of, the participant must make adequate provision for the Company’s federal,

state or other tax withholding obligations, if any, that arise upon the exercise of the stock purchase right or the disposition of

the Stock. At any time, the Company may, but shall not be obligated to, withhold from the participant’s compensation the

amount necessary for the Company to meet applicable withholding obligations, including without limitation any withholding

required to make available to the Company any tax deductions or benefits attributable to the sale or early disposition of

Stock purchased by the participant.

(f) $25,000 Limitation. Notwithstanding anything in the Plan to the contrary, no employee shall be granted a stock

purchase right under the Plan which permits his rights to purchase Stock under the Plan and under all other employee stock

purchase plans of the Company and its parent corporation and Subsidiaries to accrue at a rate which exceeds $25,000 of

Fair Market Value of Stock (determined at the time such stock purchase right is granted) for each calendar year in which

such stock purchase right is outstanding at any time (within the meaning of Section 423(b)(8) of the Code). Any payroll

deductions in excess of the amount specified in the foregoing sentence shall be returned to the participant as soon as

administratively feasible.

(g) Special Restriction on Participation. Any provisions of the Plan to the contrary notwithstanding, no Eligible

Employee shall be granted a stock purchase right under the Plan to the extent that, immediately after the grant, such Eligible

Employee (or any other person whose stock would be attributed to such Eligible Employee pursuant to Section 424(d) of the

Code) would own capital stock of the Company and/or hold outstanding options to purchase such stock possessing 5% or

more of the total combined voting power or value of all classes of the capital stock of the Company, its parent corporation or

any Subsidiary.

8. Exercise of Stock Purchase Rights.

(a) General Statement. Subject to the limitations set forth in paragraph 7, unless a participant withdraws from the Plan

as provided in paragraph 9, each participant in the Plan automatically and without any act on his part shall be deemed to

have exercised his stock purchase right on each Purchase Date to the extent of his unused payroll deductions under the

Plan and to the extent the issuance of Stock to such participant upon such exercise is lawful.

(b) Delivery of Shares to Custodian. As soon as practicable after each Purchase Date, the Company shall deliver to a

custodian selected by the Committee one or more certificates representing (or shall otherwise cause to be credited to the

account of such custodian) the aggregate number of whole shares of Stock with respect to which stock purchase rights were

exercised on such Purchase Date of all of the participating employees hereunder. Such custodian shall keep accurate

records of the beneficial interests of each participant in such shares by means of participant accounts under the Plan, and

shall provide each participant with periodic statements with respect thereto as may be directed by the Committee. The

Committee may require that shares be retained with such custodian, or other designated broker or agent for a designated

period of time and/or may establish other procedures to permit tracking of disqualifying dispositions of such shares. If the

Company is required to obtain from any U.S. commission or agency authority to issue any such shares, the Company shall

seek to obtain such authority. Inability of the Company to obtain from any commission or agency (whether U.S. or foreign)

authority which counsel for the Company deems necessary for the lawful issuance of any such shares shall relieve the

Company from liability to any participant in the Plan except to return to him the amount of his payroll deductions under the

Plan which would have otherwise been used upon exercise of the relevant stock purchase right.

C-4 HALLIBURTON 2026 Proxy Statement www.halliburton.com

(c) Withdrawal of Shares. A participant may, at any time, in such form and manner as established by the custodian,

direct the custodian to deliver to the participant all or part of the shares held by the custodian in his account or to sell such

shares and deliver to the participant the proceeds therefrom, less applicable expenses.

(d) Dividends. With respect to an individual’s Stock held by the custodian pursuant to subparagraph 8(b), the participant

may request the custodian to reinvest in additional shares of Stock for such participant’s account any cash dividends

received by the custodian and attributable to such Stock. Otherwise, the participant will receive dividends in cash. The

custodian shall, in accordance with procedures adopted by the custodian, facilitate the participant’s voting rights attributable

to shares held in participant’s account.

9. Withdrawal from the Plan.

(a) General Statement. Any participant may withdraw in whole from the Plan prior to the Purchase Date relating to a

particular Purchase Period. Partial withdrawals shall not be permitted. A participant who wishes to withdraw from the Plan

must timely deliver to the Company a notice of withdrawal in a form prepared by the Company during the Purchase Period at

a time and in a manner prescribed by the Committee. The Company shall, as soon as administratively practicable, following

the receipt of the notice of withdrawal, refund to the participant the amount of his payroll deductions under the Plan which

have not yet been used to purchase shares upon the exercise of his stock purchase rights; and thereupon, automatically

and without any further act on his part, his payroll deduction authorization and his interest in unexercised stock purchase

rights under the Plan shall terminate in full.

(b) Eligibility Following Withdrawal. A participant who withdraws from the Plan shall be eligible to participate again in

the Plan upon expiration of the Purchase Period during which he withdrew (provided that he is otherwise an Eligible

Employee at such later time).

10. Termination of Eligible Employment. If the employment of a participant with the Company terminates for any

reason whatsoever or the participant ceases to be an Eligible Employee, then his participation in the Plan automatically and

without any act on his part shall terminate as of the date of such termination of employment or change in status. The

Company shall, as soon as administratively practicable, refund to him (or his estate or personal representative, as the case

may be) the amount of his payroll deductions under the Plan which have not yet been used to purchase Stock, and

thereupon his interest in unexercised stock purchase rights under the Plan shall terminate in full.

11. Restriction Upon Assignment of Stock Purchase Rights. A stock purchase right granted under the Plan shall not

be transferable. Each stock purchase right shall be exercisable, during a participant’s lifetime, only by the participant to

whom granted. The Company shall not recognize and shall be under no duty to recognize any assignment or purported

assignment by an employee of any of his stock purchase rights under the Plan.

12. No Shareholder Rights or Privileges Until Exercise of Stock Purchase Rights. With respect to shares of Stock

subject to a stock purchase right, a participant shall not be deemed to be a shareholder, and he shall not have any of the

rights or privileges of a shareholder, until such stock purchase right has been exercised and shares delivered pursuant to

subparagraph 8(b).

13. Changes in Stock; Adjustments. Whenever any change is made in the Stock, by reason of a stock dividend or by

reason of subdivision, stock split, reverse stock split, recapitalization, reorganization, combination, reclassification of shares

or other similar change, appropriate action will be taken by the Committee to adjust any or all of (i) the number and type of

shares subject to the Plan, (ii) the number and type of shares subject to outstanding stock purchase rights and (iii) the

Purchase Price with respect to any of the foregoing.

In the event of a Corporate Change, unless a successor corporation assumes or substitutes new stock purchase rights

(within the meaning of Section 424(a) of the Code) for all stock purchase rights then outstanding, (i) the Purchase Date for

all stock purchase rights then outstanding shall be accelerated to a date fixed by the Committee prior to the effective date of

the Corporate Change and (ii) upon such effective date any unexercised stock purchase rights shall expire and the

Company promptly shall refund to each participant the amount of such participant’s payroll deductions under the Plan which

have not yet been used to purchase Stock.

14. Use of Funds; No Interest Paid. All funds received or held by the Company under the Plan shall be included in the

general funds of the Company free of any trust or other restriction, and may be used for any corporate purpose. No interest

shall be paid to any participant on amounts credited to his account.

15. Term of the Plan. The Plan was originally effective July 1, 2002. This amended and restated Plan shall be effective

as of the date it was amended and restated, provided it is approved by stockholders. If not sooner terminated under the

provisions of paragraph 16, the Plan shall automatically terminate upon and no further payroll deductions shall be made and

no further stock purchase rights shall be granted after the date all of the shares of Stock reserved for issuance under the

Plan and the Sub-Plan, as increased and/or adjusted from time to time, have been sold under the Plan and the Sub-Plan. If

on the final Purchase Date there is an insufficient number of shares of Stock available for all purchases under stock

purchase rights exercised on such date, the number of available shares shall be prorated among the then purchasing

HALLIBURTON 2026 Proxy Statement C-5

participants in an equitable manner as determined by the Committee based on their deductions for such Purchase Period

and all remaining amounts shall be returned to the participants.

16. Amendment or Termination of the Plan. The Board in its discretion may terminate the Plan at any time with respect

to any Stock for which stock purchase rights have not theretofore been granted. The Board shall have the right to alter or

amend the Plan or any part thereof from time to time; provided, however, that, except as provided below, no change in any

stock purchase right theretofore granted may be made that would materially impair the stock purchase rights of the

participant without the consent of such participant. In the event the Board determines that the ongoing operation of the Plan

may result in unfavorable financial accounting consequences, the Board may, in its discretion and, to the extent necessary

or desirable, modify or amend the Plan to reduce or eliminate such accounting consequence including, but not limited to (i)

altering the Purchase Price for any Purchase Period including a Purchase Period underway at the time of the change in

Purchase Price; and (ii) shortening any Purchase Period so that Purchase Period ends on a new Purchase Date, including a

Purchase Period underway at the time of the Board action.

17. Securities Laws. The Company shall not be obligated to issue any Stock pursuant to any stock purchase right

granted under the Plan at any time when the offer, issuance or sale of shares covered by such stock purchase right has not

been registered under the Securities Act of 1933, as amended, or does not comply with such other state, federal or foreign

laws, rules or regulations, or the requirements of any stock exchange upon which the Stock may then be listed, as the

Company or the Committee deems applicable and, in the opinion of legal counsel for the Company, there is no exemption

from the requirements of such laws, rules, regulations or requirements available for the offer, issuance and sale of such

shares. Further, all Stock acquired pursuant to the Plan shall be subject to the Company’s policies concerning compliance

with securities laws and regulations, as such policies may be amended from time to time. The terms and conditions of stock

purchase rights granted hereunder to, and the purchase of shares by, persons subject to Section 16 of the Exchange Act

shall comply with any applicable provisions of Rule 16b-3. As to such persons, the Plan shall be deemed to contain, and

such stock purchase rights shall contain, and the shares issued upon exercise thereof shall be subject to, such additional

conditions and restrictions as may be required from time to time by Rule 16b-3 to qualify for the maximum exemption from

Section 16 of the Exchange Act with respect to Plan transactions.

18. No Restriction on Corporate Action. Nothing contained in the Plan shall be construed to prevent the Company or

any Subsidiary from taking any corporate action that is deemed by the Company or such Subsidiary to be appropriate or in

its best interest, whether or not such action would have an adverse effect on the Plan or any stock purchase right granted

under the Plan. No employee, beneficiary or other person shall have any claim against the Company or any Subsidiary as a

result of any such action.

19. Miscellaneous Provisions.

(a) Number and Gender. Wherever appropriate herein, words used in the singular shall be considered to include the

plural and words used in the plural shall be considered to include the singular. The masculine gender, where appearing in

the Plan, shall be deemed to include the feminine gender.

(b) Headings. The headings and subheadings in the Plan are included solely for convenience, and if there is any conflict

between such headings or subheadings and the text of the Plan, the text shall control.

(c) Not a Contract of Employment. The adoption and maintenance of the Plan shall not be deemed to be a contract

between the Company or any Participating Company and any person or to be consideration for the employment of any

person. Participation in the Plan at any given time shall not be deemed to create the right to participate in the Plan, or any

other arrangement permitting an employee of the Company or any Participating Company to purchase Stock at a discount,

in the future. The stock purchase rights and obligations under any participant’s terms of employment with the Company or

any Participating Company shall not be affected by participation in the Plan. Nothing herein contained shall be deemed to

give any person the right to be retained in the employ of the Company or any Participating Company or to restrict the right of

the Company or any Participating Company to discharge any person at any time, nor shall the Plan be deemed to give the

Company or any Participating Company the right to require any person to remain in the employ of the Company or such

Participating Company or to restrict any person’s right to terminate his employment at any time. The Plan shall not afford any

participant any additional right to compensation as a result of the termination of such participant’s employment for any

reason whatsoever.

(d) Compliance with Applicable Laws. The Company’s obligation to offer, issue, sell or deliver Stock under the Plan is

at all times subject to all approvals of and compliance with any governmental authorities (whether domestic or foreign)

required in connection with the authorization, offer, issuance, sale or delivery of Stock as well as all federal, state, local and

foreign laws. Without limiting the scope of the preceding sentence, and notwithstanding any other provision in the Plan, the

Company shall not be obligated to grant stock purchase rights or to offer, issue, sell or deliver Stock under the Plan to any

employee who is a citizen or resident of a jurisdiction the laws of which, for reasons of its public policy or otherwise, prohibit

the Company from taking any such action with respect to such employee.

C-6 HALLIBURTON 2026 Proxy Statement www.halliburton.com

(e) Severability. If any provision of the Plan shall be held illegal or invalid for any reason, said illegality or invalidity shall

not affect the remaining provisions hereof; instead, each provision shall be fully severable and the Plan shall be construed

and enforced as if said illegal or invalid provision had never been included herein.

(f) Governing Law. All provisions of the Plan shall be construed in accordance with the laws of Delaware except to the

extent preempted by federal law.
