    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 Directors since 2022, each of 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.

  9. Shareholder Engagement

    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.

A Note About Charitable Giving and Matching. Halliburton 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.

  72. Shareholder Outreach and Board Activity

    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.

  75. QHow does the Compensation Committee determine Halliburton’s Comparator Peer Group?

    QHow does the Compensation Committee determine Halliburton’s Comparator Peer Group? AThe 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 44 for additional details on this change.)

  76. Determination of CEO Target Total Compensation

    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 50th 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.

  77. Determination of CEO Target Total Compensation

    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.

  84. Use of Independent Consultants and Advisors

    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.

  85. Comparator and Performance Peer Companies

    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:

  86. Comparator and Performance Peer Companies

    | 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. |

  87. 2025 Comparator Peer Group

    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

    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 2025 Comparator Peer Group is unchanged from 2024. This peer group was utilized to determine market levels of total compensation for the 2025 plan year:

  90. 2025 Comparator Peer Group

    | 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 |

  91. 2025 Comparator Peer Group

    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 50th 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 25th, 50th, and 75th percentiles of the Comparator Peer Group to current compensation for each NEO.

  92. 2025 Performance Peer Group

    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:

  93. 2025 Performance Peer Group

    | 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. | |

  94. 2025 Performance Peer Group

    | 58 | HALLIBURTON | 2026 Proxy Statement | www.halliburton.com |

  95. 2025 Performance Peer Group

    With support from its independent compensation consultant, the Compensation Committee selected and approved the above-listed companies because they: (1) have similar cyclicality and capital investment structures as Halliburton; (2) are in oil and natural gas drilling or oil and natural gas equipment 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.

  96. Base Salary

    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 salaries effective January 1, 2025.

  97. Base Salary

    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.

  98. Short-Term (Annual) Incentive

    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.

  99. Short-Term (Annual) Incentive

    | HALLIBURTON | 2026 Proxy Statement | 59 |

  100. 2025 Financial Metrics

    (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.

  101. 2025 Performance Results

    | Category | Weight | Performance Measures | Threshold | Target | Maximum | Actual | | Financial | 60% | Net Operating Profit After Tax | $2.188B | $2.398B | $2.608B | $1.753B | | | 20% | Asset Turns | 1.527 | 1.558 | 1.589 | 1.627 | | Non-Financial Strategic | 15% | Sustainability | | | | Achieved | | | 5% | Our People | | | | Achieved |

  102. Long-Term Incentives

    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:

  103. Long-Term Incentives

    | 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 |

  104. Long-Term Incentives

    (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.

  105. Individual Incentive Opportunities

    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.

  106. A Closer Look at the Performance Unit Program

    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.

  107. A Closer Look at the Performance Unit Program

    | HALLIBURTON | 2026 Proxy Statement | 63 |

  108. A Closer Look at the Performance Unit Program

    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:

  109. A Closer Look at the Performance Unit Program

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

  110. A Closer Look at the Performance Unit Program

    | 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. |

  111. A Closer Look at the Performance Unit Program

    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.

  112. Performance Matrix

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

  113. Performance Matrix

    | | | | Relative TSR Modifier | | | | | | Unadjusted Incentive Opportunity(2) | Lower Quartile Performance ≤25th percentile | 2nd/3rd Quartile Performance >25th percentile & <75th percentile | Upper Quartile Performance ≥75th percentile | | | | | | MULTIPLIER(3) | | | | | | 75% | 100% | 125% | | HAL ROCE Ranking(1) vs. Performance Peer Group | Below Threshold <25th percentile | 0% | 0% (0% x 75%) | 0% (0% x 100%) | 0% (0% x 125%) | | | Threshold 25th percentile | 25% | 18.75% (25% x 75%) | 25% (25% x 100%) | 31.25% (25% x 125%) | | | Target 55th percentile | 100% | 75% (100% x 75%) | 100% (100% x 100%) | 125% (100% x 125%) | | | Challenge ≥75th percentile | 200% | 150% (200% x 75%) | 200% (200% x 100%) | 250% (200% x 125%) |

  114. 2023 PUP Cycle Results

    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 75th 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.

  115. Policies and Practices Related to the Grant of Certain Equity Awards

    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.

  116. Hedging and Pledging Policy

    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.

  117. Elements of Post-Termination Compensation and Benefits

    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.

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

    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.

    (2)The amounts shown for Compensation Actually Paid have been calculated in accordance with Item 402(v) of Regulation S-K and do not reflect compensation actually earned, realized, or received by the Company’s NEOs. These amounts reflect the Summary Compensation Table Total with certain adjustments as described in footnote 3 below. (3)Compensation Actually Paid reflects the exclusions and inclusions of certain amounts for the PEO and the Non-PEO NEOs as set forth below. Equity values are calculated using valuation methodology that is consistent with the equity awards that we accounted for under FASB ASC Topic 718. Amounts in the Exclusion of Stock Awards column are the amounts from the Stock Awards column set forth in the Summary Compensation Table.

    (4)The Peer Group TSR set forth in this table utilizes the Philadelphia Oil Service Index (OSX), which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended December 31, 2025. The comparison assumes $100 was invested for the period starting December 31, 2020, through the end of the listed year in the Company and in the OSX, respectively. Historical stock performance is not necessarily indicative of future stock performance. (5)We determined Return on Capital Employed (ROCE) to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs in 2025, as we did in 2022-2024. More information on ROCE can be found in the Long-Term Incentives section of Compensation Discussion and Analysis. This performance measure may not have been the most important financial performance measure for years 2021 and 2020, and we may determine a different financial performance measure to be the most important financial performance measure in future years.

  162. CEO Pay Ratio

    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.

  164. CEO Pay Ratio

    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.
