Our international operations today represent just over half of our total business. Halliburton’s international revenue grew 17% in 2023 and delivered improved margins and higher returns throughout the year, despite our exit from Russia in 2022. Throughout the international markets in which we operate, we deliver shareholder value through disciplined capital allocation, which means we strategically deploy assets to markets where customers recognize the value of our reliable execution and collaboration. Our next-generation equipment delivers leading-edge performance for our customers and structurally improved returns for Halliburton. Our 2023 results demonstrate the success of our profitable international growth strategy. In the international markets in which we operate, we expect higher international spending for multiple years. To deliver strong shareholder returns through this multi-year upcycle, we will execute on our Chairman, President and CEO Jeff Miller value proposition, deploy leading technologies, and exercise disciplined capital allocation. 2023 was a great year for Halliburton and its shareholders. The power of Halliburton’s strategy delivered some of the best business performance we have seen in a decade. We recorded revenue of $23 billion, operating income of $4.1 billion, operating margin of 18%, and return on capital employed of 19%. In addition, we generated $3.5 billion of cash flow from operating activities and $2.3 billion of free cash flow. Consistent with our shareholder returns framework, we returned $1.4 billion to shareholders in the form of dividends and stock repurchases and we retired approximately $300 million of debt. We achieved these results through execution on Halliburton's five key strategies — Deliver Profitable International Growth, Maximize Value in North America, Accelerate Digital and Automation, Improve Capital Efficiency, and Advance a Sustainable Energy Future. By delivering on our value proposition: to collaborate and engineer solutions to maximize asset value for our customers, we deepened our relationships with customers, improved profitability, and delivered on our strategy. Our commitment to doing business the REDWay: Responsibly, Ethically, and Diligently guided this strategic execution and these results. Deliver Profitable International Growth Halliburton operates in over 70 countries around the world — in both on- and off-shore markets, and across all major product Maximize Value in North America Halliburton is the only globally integrated service company with the leading presence in North America, the world’s largest oil field services market. Our leadership means we have the resources to invest in next-generation technologies, infrastructure to commercialize these technologies at scale, and expertise to execute at the highest levels of efficiency. Today, the North America market continues to evolve with a growing segment of customers focused on productivity, efficiency, and reserve recovery. This growing customer segment employs long term development programs, targets improved reservoir recovery through technology, and minimizes operating cost through service efficiencies. We expect Halliburton to extend its technology leadership, deliver unmatched efficiency through our design innovations, and execute on its strategy to maximize value in North America. Accelerate Digital and Automation Halliburton’s strategy to advance digital and automation has transformed both our service delivery and our business performance. Digital and automation lower our costs, improve safety for our personnel, and lower our carbon footprint. Today, that investment in digital and automation exists in our product lines including innovations such as remote offshore cementing jobs, automated directional drilling, and predictive pump maintenance. Halliburton 2023 Annual & Sustainability Report Introduction 6 Halliburton’s service quality leadership and leading approach to digital and automation strengthens our execution for customers. To further advance our digital and automation strategy, Halliburton has accelerated development and deployment of new digital and automation technologies that will benefit our business and that of our customers. Improve Capital Efficiency Capital efficiency improvement means we deploy innovative solutions to do more with less. Our technology and development pipeline focuses on technologies that structurally improve our capital efficiency like our iCruise® intelligent rotary steerable system and Zeus™ electric fracturing fleets. These technologies require fewer spare parts, lower maintenance expense, and structurally deliver higher returns for shareholders. Advance a Sustainable Energy Future Access to secure and reliable energy remains fundamental to economic and social development, and Halliburton is committed to advancing a sustainable energy future. Our approach to advancing this future aligns squarely with our core competencies. We work to help our customers decarbonize their operations. We advance a sustainable future through operations directly adjacent to our core operations.

We engaged in regular discussions with our shareholders, customers, employees, and others in 2023. The Halliburton website plays an important role in our outreach efforts and transparency. Shareholders We engage in consistent, open dialogue with our shareholders. In fall of 2023, our independent Directors hosted off-season meetings to better understand our shareholder priorities and concerns. We offered opportunities for engagement to shareholders who represented approximately 60% of our shares. Halliburton Directors and management communicated with 20 shareholders who represented approximately 55% of our shares and with the two largest proxy advisors, Institutional Shareholder Services Inc. and Glass Lewis. We hosted video-conferences and in-person meetings that included engagements with either Murry Gerber (Chair of the Compensation Committee) or Robert Malone (Lead Independent Director) and Halliburton senior management. We made our refreshed shareholder presentation available to the shareholders we offered to engage with even if they could not attend one of our video calls or meetings. We also offered to follow up to discuss any questions or concerns. Our 2023 updates to these materials highlight the most recent available information with regard to topics like Board oversight and engagement; executive compensation; our people; health, safety, and the environment; and sustainable energy solutions. We solicited additional shareholder feedback with our annual and quarterly reporting cycles, earnings conference calls, and investor meetings. To engage with analysts and institutional investors, Halliburton's senior management and Investor Relations team hosted regular meetings and conference calls. As part of our ongoing cadence of shareholder outreach, we participated in 16 sell-side conferences, one non-deal roadshow, and 304 investor meetings in 2023. All of this feedback was presented to and discussed among the full Board of Directors for execution of its oversight responsibility. Customers Customer feedback plays an important role in Halliburton's ability to make improvements to current solutions and to align our research and development (R&D) investments with customer needs and goals as we develop new products and solutions. Halliburton's executive leadership, business development team, and product lines conduct regular customer engagement to develop and maintain in-depth understanding of the strategies, priorities, and requirements relevant to our customers. We gain a thorough understanding of customers' short- and long-term efficiency, technology, and sustainability goals through direct communication with them. Our collaboration with our customers provide insights into ways we can best develop and offer solutions that both maximize asset value and aid efforts to further the future of energy. CEO Jeff Miller conducts site visit Halliburton 2023 Annual & Sustainability Report Introduction 11 Employees Halliburton's Government Affairs program focuses on helping government officials, policymakers, and local operations management teams understand our technologies and products. The program makes in-depth information about our business available. It also facilitates collaboration with them on issues our customers, employees, and other stakeholders prioritize. Government officials and policymakers contact us to learn from our knowledge and experience about energy-related topics. In recent years, these conversations have often focused on our new technologies, electric fracturing, carbon capture, and geothermal energy opportunities. At times, we also assist foreign service offices, consulates, and embassies around the world as a resource on questions about technology and local content. Local Communities and Non-Governmental Organizations Halliburton promotes the economic and social well-being of the communities where we work. We meet with non-governmental organizations, community groups, and nonprofits to better understand their concerns and requirements; engage in charitable giving to local community organizations through corporate giving initiatives and charitable foundations; and host volunteer opportunities focused on education, health and safety, environmental cleanup and awareness, and social services to give back to our communities. We promote a welcoming and inclusive work environment in order to ensure the well-being of our employees and our own continued success. To encourage an environment of openness and teamwork across our global workforce, we engage in activities and initiatives like town hall meetings, Check-ins (our performance-management process), workshops, employee resource groups, performance feedback, and a biannual Employee Pulse Survey (EPS). These activities and initiatives, which occur in local geographies or at the global level for individual product service lines or functions, help us strengthen a workplace culture in which Halliburton employees feel their voices are heard. Halliburton considers our biannual EPS an important opportunity to hear from employees about what matters to them. The input we receive helps us identify ways we can improve our workplace for all employees. Our August 2023 EPS yielded a record-high response rate. Read more in the Employee Pulse Survey section of this report. Suppliers Halliburton's ability to provide world-class service to our customers is enabled in part by our cultivation of a resilient, sustainable supply chain that creates value for Halliburton and our customers. We engage with an array of suppliers, both locally and globally, who share our commitment to integrity and ethical business practices. To ensure our ethical standards are upheld, we gather feedback from and collaborate with our suppliers on matters that include health and safety procedures, human rights compliance, and environmental impact. Our sustainability approach and sourcing platforms, meetings, workshops, and training sessions help facilitate consistent, in-depth engagement with suppliers. Regulators Halliburton is a global company, and our operations take place in countries and jurisdictions that have varying regulatory requirements. We remain actively engaged with the regulators and agencies that create and enforce regulatory standards to protect the environmental, social, and economic fabrics of the countries where our operations take place.

EXECUTIVE COMPENSATION Halliburton's executive compensation program focuses on incentivizing performance, maximizing returns, and building shareholder value. It is integrated with our overall business strategy and management processes, and is performance-based, at-risk, and long-term. Our long-term incentive plan includes relative performance measures, and our annual incentive plan combines financial and non-financial strategic metrics. For additional information, visit our 2024 Proxy Statement. Halliburton's commitment to shareholder input resulted in numerous, substantive changes to the structure and governance of our executive compensation program in the last few years. Most recently, we implemented a payout cap in our long-term incentive plan for negative Return on Capital Employed (ROCE) performance and increased the target performance level for relative ROCE. These changes directly reflect feedback we received from our shareholders and further strengthened the program's design through alignment of pay opportunities, business performance, and pay outcomes, and demonstrated our commitment to put forth a market-competitive program that produces the results our investors expect.

GLOBAL IT INFRASTRUCTURE Halliburton's IT strategy includes modernized infrastructure, networks, and applications that provide agility, scalability, and flexibility to our business and customers. This design aligns with and supports our broader digital and automation strategy. We continue our efforts to optimize all applications deployed to cloud-based digital platforms. This includes applications that are new to the cloud as well as those we migrated from previous platforms. These efforts reduced the on-premise infrastructure required for our work. At the end of 2023, we achieved our goal to reduce our global data center footprint by 75%. continuity, strategy, and crisis management. Halliburton reports to the Board of Directors on the results of the risk-assessment process. This process is part of Halliburton's Enterprise Risk Management (ERM) program, which is designed to identify, mitigate, and manage enterprise-level risks to our organization as well as other strategic risks. ANNUAL ENTERPRISE RISK ASSESSMENT Halliburton's refreshed risk-assessment process continued in 2023. We conduct this process with our partnership with a global leader in ERM programs. This streamlined and collaborative approach to strategic risk assessments is one way we identify and prioritize top risks. The process consists of yearly workshops that facilitate open dialogue, debate, and existent and emergent risk evaluation. This year, 79 Halliburton executives participated to discuss, evaluate, and score risks based on their potential impact, likelihood of occurrence, and risk-mitigation preparedness. Workshop results provided valuable feedback for focusing risk-mitigation attention and opportunities for process optimization. We incorporate insights gained into upcoming plans and utilize them to help Halliburton minimize risks and maximize opportunities as it achieves its strategic plans. Halliburton 2023 Annual & Sustainability Report Governance 17 CYBERSECURITY Halliburton takes every threat to cybersecurity seriously. Our Board receives quarterly updates about cybersecurity matters and Halliburton's Audit Committee receives an in-depth annual review on the topic. Halliburton invests significant resources to protect our systems and data. We do this in ways that align with industry standards, such as the National Institute of Standards and Technology (NIST) Cyber Security Framework, NIST 800-53, NIST 800-82, and International Electrotechnical Commission 62443. The following are examples of measures taken to implement our Defense-in-Depth design philosophies for Information Technology (IT) and Operational Technology (OT) systems: Halliburton continued to perform OT security self-assessments for all of our product lines in 2023. These assessments promote proper governance of cyber controls; help us evaluate evolving cyber risks; and improve our product line network segmentation, monitoring, and endpoint security management. We regularly evaluate advanced cybersecurity technologies with potential to help Halliburton expand our portfolio of OT security solutions. In 2023, we further enhanced our annual cybersecurity training program. We launched additional training on specific subjects, such as phishing and privileged access management, that are now required for select groups of Halliburton personnel and optional for the rest of our employees. The groups that are required to complete these new training courses do so alongside Halliburton's annual cybersecurity training course, which is required of all our employees and contractors.

Tier 1 suppliers representing: spend engaged 89% of Halliburton's annual 68% of Halliburton's annual spend registered G5 SUPPLY CHAIN GOVERNANCE Halliburton works with suppliers who share our commitment to integrity and ethical business practices. We use a standard approach to screen suppliers and measure their compliance with our rules, terms, and conditions. We also review and monitor our current suppliers' practices to confirm they comply with Halliburton's policies. Learn more about our Supplier Management System, local supplier procurement policies, modern slavery and trafficking prevention, conflict minerals, and supplier compliance and training-related expectations on the Supplier Relations page of the Halliburton website. DRIVING A SUSTAINABLE VALUE CHAIN Halliburton knows effective due diligence of our supply chain is essential to build and maintain sustainable operations. It is important to select suppliers that operate sustainably. Halliburton's work to select and qualify suppliers includes evaluations of suppliers' sustainability commitments. We expect our suppliers to improve with us in sustainability matters. We also encourage our suppliers to track their sustainability performance and proactively pursue continuous improvement. SUPPLY CHAIN MONITORING PLATFORM Halliburton continued to develop and implement a digital supply chain monitoring platform in 2023. This cloud-based platform collects and monitors sustainability data from suppliers on a wide range of topics that include human rights, conflict minerals, supplier diversity, and carbon footprint. Halliburton uses this system to engage with our supply chain partners on key sustainability issues, identify and prioritize risks, manage supplier corrective action plans, and track vendor progress on carbon footprint reduction. Halliburton 2023 Annual & Sustainability Report Governance 22 PERFORMING DUE DILIGENCE IN OUR SUPPLY CHAINS Policies Halliburton's contracted suppliers must commit to protect and uphold the fundamental human rights of their employees as defined by the UN Universal Declaration of Human Rights. We use our Supplier Ethics Letter and Supplier Ethics Statement to communicate ethical expectations to our suppliers. In 2023, we enhanced our supply chain policies by embedding our sustainability commitments and requirements in them. Risk Assessment During onboarding, we require potential suppliers to engage in a risk-evaluation process via our procurement system. Depending on supplier risk level, we collect information such as insurance documentation and safety risk assessments. We also conduct screenings for export controls. We then use our supply chain monitoring platform to conduct sustainability assessments. As a data collection and mapping tool, this platform plays an important role in making it possible for Halliburton to analyze data, pinpoint risks within our supply chain, and prioritize areas for follow up. When we work to determine which risk levels to assign to suppliers, we assess them based on relationship, category, and geography. Our Approach to Supply Chain Sustainability Communication & Training Reporting & Accountability Embedding sustainability in supply chain processes Halliburton includes evolving international Human Rights legislation, particularly import and trade restrictions, in our risk assessment methodology. In the course of risk assessment, we consult international standards, such as the UN Guiding Principles for Business and Human Rights and The Organization for Economic Co-operation and Development Due Diligence Guidance for Responsible Business Conduct. The supply chain monitoring platform has enabled Halliburton to expand our supplier human rights due diligence program and take effective action to reduce risks and improve sustainability performance over the long term. It administers questionnaires to suppliers about key Human Rights and Labor topics. We have used the platform to conduct Human Rights and Labor evaluation for 4,496 suppliers (which comprises 56% of our global spend). Human Rights Audit and Supplier Evaluation In 2023, we continued to enhance our high-risk supply chain due diligence. Through Halliburton's ongoing collaboration with a third-party human rights auditor, we maintained our practice of on-site human rights audits of suppliers. We consider the scale of our business with particular suppliers and the nature of the goods or services they provide to determine the proper scope and form of our audits. We conduct Workplace Conditions Assessments, Labor Provider Audits, and Service Provider Audits, among others. Halliburton evaluates our critical suppliers annually. In these evaluations, we look at suppliers' risks related to safety, quality, environment, social responsibility, economics, and corporate governance. Suppliers must respond to a questionnaire that asks about their level of compliance with Halliburton's COBC, safety standards, and requirements. If a supplier is found to be non-compliant with Halliburton's standards, our response actions can lead to supplier termination.

In 2023, we engaged 5,992 suppliers with questions about diversity via our cloud-based supply chain monitoring platform. This inquiry was designed to validate data and identify diverse vendors in our network. We also expanded supplier diversity to include disabled- and veteran-owned businesses. Conflict Minerals Halliburton is a member of the Responsible Minerals Initiative. We work with our suppliers to make sure they ethically source conflict minerals. Non-compliant suppliers are subject to termination or corrective actions. In 2023, our cloud-based supply chain monitoring platform enabled us to increase our supplier response rate from 78% to 86%. It also affords us better visibility into our suppliers' actions; greater ease in collaboration with suppliers on appropriate remedial or corrective actions; and a more intuitive assessment platform. SUPPLY CHAIN TRAINING To deliver training about sustainability and supply chain mapping to our internal personnel and external suppliers, Halliburton engages resources from professional training bodies that develop material focused on supply chain and procurement practices. In 2023, in collaboration with the Supply Chain Sustainability School, we piloted sustainability-related training to key internal employees and external stakeholders. The Supply Chain Sustainability School enables us to provide a wide range of sustainability training on a variety of topics, including modern slavery, ethical procurement, environmental protection, and climate change. This includes the International Petroleum Industry Environmental Conservation Association (IPIECA) Labor Rights Training, which covers topics such as fair recruitment, worker grievance mechanisms, and forced labor. We also continued our internal training on Supply Chain Sustainability Awareness for supply chain employees in 2023. This training covers a range of key sustainability topics relevant to our supply chain, including emissions, supply diversity, supply chain risk mapping, modern slavery and related legislation, the UN Sustainable Development Goals, and UN Guiding Principles on Business and Human Rights.

ENVIRONMENTAL FACILITY CERTIFICATIONS The HMS complies with industry-standard certification programs — including International Organization for Standardization (ISO) 14001 and API RP 75 — as do all the processes and procedures it contains. Many of Halliburton's product lines and facilities are externally certified in accordance with ISO 14001 and business requirements. In 2023, 65 Halliburton facilities held ISO 14001 certifications. SUSTAINABILITY AWARENESS TRAINING In 2023, we launched a Company-wide Sustainability Awareness Training course. The course helps employees build foundational sustainability-related knowledge and educates them about Halliburton's guiding principles, commitments, and the initiatives we have undertaken in pursuit of our sustainability goals. The course has been completed by over 90% of our employees. A successful journey toward our goals includes educating employees about Halliburton's sustainability focus and progress. Lab employee in Saudi Arabia Halliburton 2023 Annual & Sustainability Report Environmental 36 WATER STEWARDSHIP Halliburton stewards water in ways that reduce and optimize our use of water resources. We work internally and collaborate with our customers on a global scale to reduce, reuse, and repurpose — or "3R" — fluid resources to the fullest possible extent. Halliburton improves water quality, conserves water, and advances sustainable, cost-effective water management processes for ourselves and our customers where we are able. We report water-use data for Company-owned and Company-leased locations in the U.S., Canada, and most of Halliburton's global facilities. Halliburton has established a water-use reduction toolkit that is available for use at our facilities, which was implemented in 2023 by our top water-consuming facilities in potentially water-stressed areas. We used our Water Calculator to establish a water balance for each of these locations. The calculator helps a facility identify and quantify water sources used at the site, on-location uses of water, and the site's wastewater discharges. From this activity, we noticed that higher volumes of water tend to be required for in-product uses, auxiliary processes, domestic use, and/or landscape irrigation. We then used the Water Reduction Plan Template to evaluate water-use reduction opportunities at our top locations. This template facilitates the identification and evaluation of water-use reduction strategies and helps establish site-specific reduction targets. Water-use reduction strategies that have resulted from this process include, but are not limited to, improvements to leak awareness and identification; replacement or enhanced maintenance for older water-consuming appliances and fixtures; adoption of drought-friendly vegetation and xeriscaping; and implementation of systems that recycle and reclaim water. In 2023, we continued our engagement with sites in potentially water-stressed areas to facilitate improvements and monitor progress against location-specific reduction targets.

The Halliburton 2023 Annual & Sustainability Report Environmental 37 WASTE MANAGEMENT AND REDUCTION Halliburton has developed a number of tools that support waste management and reduction efforts at our facilities. Our 2023 waste generation data include all manufacturing locations; all U.S. locations; and any non-U.S. locations with methods associated with that waste. Another template, Waste Segregation Posters, provides information on how to create easy-to-understand posters that guide facility personnel on proper waste segregation and storage. Halliburton has also developed a Waste Minimization Decision Guide to help facilities identify opportunities to prevent, reduce, reuse, and recycle waste from their highest-volume and building footprints larger than two acres (8,092 m²) or that highest-emissions waste streams. facilitate activities with potential to generate particularly high levels of waste. The Waste Data App makes it possible to more accurately collect and report on waste generation and disposal data. On a quarterly basis, Halliburton facilities enter data into the app for each waste stream that is sent offsite for treatment, storage, disposal, or recycling. The Waste Stream Identification Template is a step-by-step guide that supports the identification and classification of different types of waste and provides guidance on the segregation, handling, and disposal In early 2023, Halliburton locations that generate large volumes of waste used one or more of these tools to identify waste reduction opportunities, set reduction targets, establish reduction plans, and monitor progress against targets.

Our goal was to extend maintenance intervals and minimize waste from hydraulic fracturing pump oil changes while maintaining service quality and performance. The team tested different types and viscosity of transmission oil. The best oil blend proved able to improve performance and increase time between rounds of maintenance, which lengthened oil replacement cycles by 317%. This has reduced the amount of oil required to service our North America Land hydraulic fracturing pump fleet by 165,819 gallons per year. The project helped our team reduce waste, reduce equipment downtime, and further improve the reliability of our equipment. Waste Minimization at Our Norway Tananger Main Facility Our Norway Tananger Main Facility implemented a program in 2023 to segregate waste streams. The program led to a 73% year-over-year reduction in the amount of waste the site generated per hours worked.

SAFETY S1 HEALTH AND S4 HUMAN RIGHTS PEOPLE S2 OUR S5 LOCAL COMMUNITIES S3 TRAINING AND DEVELOPMENT Halliburton 2023 Annual & Sustainability Report Social 39 S1 HEALTH AND SAFETY At Halliburton, the safety of our employees and contractors is our priority. Our long-term safety programs and processes are tried, tested, and well-established. These programs and processes are part of our Journey to ZERO. They include Halliburton Critical Focus Areas (CFAs), Life Rules, Stop Work Authority (SWA), Management of Change, Significant Incident Review, and Tiered Assurance. Learn more on the Health, Safety, Environment (HSE) and Service Quality (SQ) page of our website. In 2023, as business activity levels continued to rise, operational discipline to our Halliburton Management System (HMS) and focus on execution enabled us to outperform our industry group HSE indicators and improve our service quality performance. JOURNEY TO ZERO The Journey to ZERO approach to safety and service quality expresses our commitment to our employees, customers, and communities. It demonstrates that we prioritize high standards, embrace challenges, and make no compromises when we execute on our goals. Specific Journey to ZERO focus areas shift each year, but the guiding principles remain consistent: ■ ■ ■ ■ ■ ■ Leadership commitment Continuous improvement of the HMS Training and competency Communicate and address risks Technology and process improvement Verification of our HSE and SQ performance Our 2023 Journey to ZERO efforts included a continued focus on risk management, and we completed our first full year of leadership visit metric tracking. In addition, we tracked progress on our GHG emissions, waste, and water reduction efforts, which are highlighted in the Environmental section of this report. Halliburton completed 100% of our 2023 Journey to ZERO objectives. Our Occupational Safety - Journey to ZERO Sustainability Commitments ■ Target outperforming total recordable incident rate and lost-time incident rate in the International Association of Drilling Contractors sector benchmarking. ■ Achieve HSE training compliance >95%, driver competency >95%, and 100% completion of our annual Journey to ZERO strategic objectives.

To build on our successful 2022 updates to risk management training in North America, regional delegates recognized for HSE and SQ leadership completed a series of Train the Trainer modules in 2023 to become internally certified Risk Management 5 Checks to Go trainers. Globally, over 3,600 additional supervisors and frontline personnel completed the training. When HSE or SQ incidents do occur, our risk management process helps us embrace the opportunity to learn from incident investigations. These investigations sometimes lead to process changes. At other times, they reaffirm the importance of continued execution on our existing lines of defense. In 2023, we supported these efforts with the publication of an HMS guidance document that standardized the categorization of our lines of defense and critical verification activities. This document provides a more consistent approach to using the results of our investigations to globally prioritize improvement opportunities. At Halliburton, our lines of defense categories include the industry standard Life Rules, Critical Focus Areas, and our product service line control points. Stop Work Authority (SWA) remains a critically important part of risk management at Halliburton. Our SWA program authorizes all employees and contractors to stop a task if they observe unsafe actions or conditions, or if they have concerns regarding the controls over an HSE or SQ risk. In 2023, employee engagement in SWA remained strong, and we saw a year-over-year increase in the number of SWA observations.

MENTAL HEALTH EDUCATION AND AWARENESS Halliburton's Global Employee Assistance Program (EAP) team expanded employee- and management-focused training and education opportunities this year. An example of one such opportunity is our Lessons for Life monthly web series in which our employees can learn from expert opinions on a variety of mental health and well-being related subjects. Topics in 2023 included grief and hope in the COVID-19 pandemic as well as maintenance of healthy boundaries in the workplace. 2023 Mental Health Awareness Campaigns In 2023, Halliburton covered a variety of topics in our global mental health digital awareness campaigns that were tailored to address different regions' specific needs. We continued to incorporate mental health-themed safety topics in our safety moments, and this inclusion further emphasized how important it is to care for one's mental health. Halliburton hosted global campaigns for Mental Health Awareness Month, World Sleep Day, and World Mental Health Day and executed a neurodiversity awareness campaign in April for Autism Awareness Month. Through these campaigns, we delivered messages designed to further increase mental health awareness among all of our employees. RECRUITMENT Halliburton takes thoughtful action to cultivate a globally diverse talent pipeline that represents the communities where we operate. This begins with our investment in science, technology, engineering, and mathematics (STEM) and oil and gas programs at schools and universities. When it comes time to hire early career talent, we rely on consistent relationships with colleges, universities, and other organizations that give more visibility to opportunities that are available at Halliburton. We utilize initiatives such as internship programs at colleges and universities with underrepresented populations to build connections among diverse communities, potential hires, and Halliburton, and to eventually hire full-time employees who represent the communities in which we work and live. Our build-from-within approach to recruitment and training helps us develop early career talent into future leaders. We augment this approach with targeted recruitment efforts for senior-level positions that help introduce specific expertise and emergent skillsets to Halliburton. Outreach Our Global Talent Acquisition team conducts candidate outreach in a variety of ways that include virtual career fairs, apprenticeship programs, relationship building efforts at universities, employee referrals, and partnerships with local job candidate programs. Halliburton's outreach includes our efforts to build interest in STEM and oil and gas careers among students, a strategy that also supports local workforce development in the areas where we operate. One example of our STEM-focused outreach in Latin America is our recruitment efforts with the Development Excellence Engineer Program (DEEP). Read more about DEEP in the Local Workforce Development section of this report. Talent Acquisition In 2023, Halliburton hired 8,714 new employees. Of our total hires to STEM roles, 28% were female, a number that is higher than it was in 2022 and represents our highest number of female hires to STEM roles at Halliburton since 2010. This number compares favorably to the National Association of Colleges and Employers female graduation rates in the degrees we target in our search for new hires. Promoting female representation in these roles is a key focus at Halliburton, as our STEM roles tend to lead to operational Halliburton 2023 Annual & Sustainability Report Social 46 leadership positions. Female representation also continues to be a strong feature of Halliburton's U.S. internship programs. The number of female interns at our U.S.-based locations increased from 53 in 2022 to 73 in 2023. Rate of New Female Hires in STEM Roles 2021 2022 2023 19% 23% LOCAL WORKFORCE DEVELOPMENT Halliburton invests in local workforce development with the aim of a positive impact on communities where we work. One way we do this is by regularly hiring local talent for open positions. We have made significant progress in recent years. As of 2023, 91% of our workforce and 85% of managers are local to the countries where they work. As Halliburton strengthens investments in local workforces, 28% we increase our ability to participate in improvements to local economies. Through job creation, skill advancement, and career development, we help enhance local quality of life for employees and their families and strengthen our ability to cultivate a workforce that represents local populations. Halliburton welcomes summer interns with weeklong camp and volunteer activities PowerToFly Halliburton's partnership with PowerToFly has provided us with opportunities to better tell our story to a global, diverse audience. In 2023, we worked with PowerToFly to recruit new candidates and host several events at which Halliburton speakers shared their experiences and views on opportunities at Halliburton and within our industry. Through PowerToFly, almost 400,000 people were exposed to Halliburton's open positions, events, or webpage. Development Excellence Engineer Program Halliburton's Development Excellence Engineer Program is a college graduate recruitment initiative we deploy in Latin America. DEEP began in 2012 in Brazil and has since expanded to multiple countries in Latin America. In 2023, we standardized DEEP's requirements and structure in countries where it is implemented. Eligible candidates include STEM students in their last semester of undergraduate study and/or individuals who are within 18 months of graduation from a STEM degree. Participants engage in a four-month development program and rotate between two product service lines at Halliburton. Since 2015, over 750 "DEEPers" have completed the program, of which 387 have been hired full-time. In addition, female representation has been consistently high. On average, about 43% of DEEP participants are female. DEEP has played an important role in increasing the number of STEM hires in Latin America. DEEP has also proven to be a successful avenue of entry for career longevity as 70% of DEEP participants hired full-time since 2015 are still working at Halliburton. Halliburton 2023 Annual & Sustainability Report Social 47 INVESTMENT IN THE FUTURE As Halliburton builds a sustainable pipeline of future talent, we draw talent to our workforce through mentorship programs, charitable giving, and inclusive hiring practices. Girls Techno Summer Camp Halliburton and Prairie View A&M University (PVAMU) collaborated to host the Girls Techno Summer Camp, a three-day residential summer camp for high school-aged girls who are interested in engineering careers. The camp aimed to teach attendees technical skills, build their confidence, and inspire them to become engineers and leaders who will make a difference. Students about to enter their junior and senior year of high school were eligible to attend. They learned about design thinking, computer programming, data science, artificial intelligence, and robotics. We supported this program with a tour of our headquarters that included our manufacturing and R&D facilities and by hosting a Q&A session after the tour. STEM Saturdays and Academic Mentoring Matters In 2023, we worked with the University of Louisiana Lafayette Foundation to host STEM Saturdays and an Academic Mentoring Matters (AMM) training event for local students. STEM Saturdays are offered once a month at the Lafayette Science Museum. Halliburton began to sponsor STEM Saturdays in 2022 and we continued our support in 2023. Thus far, this event series has impacted 2,200 students in the College of Sciences. We fund an AMM leadership training event every year to equip volunteer student mentors to be leaders among their peers. Student mentors have a significant impact on their campus communities. Our AMM leadership training event helps prepare students who have elected to serve their community in this way. Halliburton volunteers and university students host science project at National Urban League conference in Houston, TX Halliburton 2023 Annual & Sustainability Report Social 48 S3 TRAINING AND DEVELOPMENT Our skilled, knowledgeable employees and the investments we make in their learning and development are what power Halliburton's success and growth. To help our employees excel in their careers and meet personal goals, we provide industry-recognized, best-in-class employee development programs, processes, and trainings. We also take action to cultivate a strong leadership pipeline of experienced talent who are prepared to help guide Halliburton into the future. TALENT DEVELOPMENT AND SUCCESSION MANAGEMENT Halliburton establishes its talent development and succession management strategies on a "build from within" philosophy. We regularly identify and develop new leaders through intentional identification and training efforts. Our strategy promotes business continuity, retention, and teamwork, and maintains a strong competitive advantage when it comes to both short- and long-term success. In 2023, female diversity and U.S. racial diversity in various roles improved. From a 2022 baseline, females in operational leadership roles increased by 6%; the females in junior operational leadership roles increased 10%; and the number of female candidates on replacement charts increased by 14%. In addition, in 2023 in the U.S., our percentage of racial diversity in management roles improved by 6% compared to 2022. To build a robust leadership pipeline, Halliburton Succession Management identifies the readiness of potential successors for critical roles. In 2023, we had an 83% internal fill rate for leadership roles and a 94% internal fill rate for executive-level positions. Our strong internal fill rate, one of the highest in the market, directly results from our process to identify successors and offer tailored development plans. Technical and Leadership Development We host processes and programs — such as Hire to Country Manager (H2CM), HalAcademy, Emerging Leader Process, and Business Leadership Development (BLD) — to recruit, Our Skilled and Committed Workforce Sustainability Commitment ■ Have a skilled and committed workforce by listening and responding to our employees’ feedback and committing to an engaged workforce that feels valued with the right support and resources to be successful. train, and promote members of our employee population who have leadership potential. This approach has facilitated high retention and continuity among Halliburton talent. It also promotes teamwork and camaraderie. Employees often rise through Halliburton together, which gives them shared experiences they can draw from when they collaborate to lead. Hire to Country Manager Process H2CM is a leadership development track for potential product service line country managers. This role is an essential managerial role and critical to Halliburton's success. The ultimate goal of H2CM is to develop strong, competent leaders who can help build an even stronger organization. The program enhances visibility into the internal talent pipeline for product service line country manager roles and other roles in the H2CM training process. Participants are trained in Halliburton's five key competencies for operational leaders: technical depths, service execution, customer focus, frontline leadership, and business acumen. In addition, H2CM is designed to be flexible so employees can engage according to their own readiness and Halliburton's available business opportunities. In 2023, H2CM helped Halliburton increase female representation in product service line country manager roles by 47% year over year. In addition, female representation increased in four out of the five H2CM phases preceding the country manager role.

Through this process, we identify and train employees who demonstrate high leadership potential who then participate in the Frontline Leader Readiness Assessment (FLRA) — a formal simulation facilitated by a leading third-party assessment authority — to assess their timing-related readiness. In 2023, more than 400 employees completed assessment for leadership potential factors and approximately 100 completed FLRA. Once they have completed the FLRA, participants receive insight on their proficiency, a leadership coach, and a tailored development plan. EMPLOYEE-DRIVEN DEVELOPMENT AND UPSKILLING Many of our employee-development and upskilling resources are designed to empower our people through facilitation of employee-driven career growth and skills development. Flexible Learning Halliburton offers employees educational opportunities in a variety of formats. Expanding these opportunities to multiple formats has made our training programs more accessible and efficient for our global workforce. We have also given individual employees latitude to engage with learning opportunities in ways that accommodate their personal situations. Content ranges from leadership, functional, general business skills, and technical training related to our products and services to emerging skills for which we want to build employee capabilities. In 2023, we delivered more than 62% of our training in non-traditional classroom environments. Halliburton also continues to offer robust in-person training opportunities. Digital Literacy Progress Halliburton continued to offer digital literacy education to employees in 2023. Our digital literacy educational opportunities help employees develop a fundamental understanding of how to use digital resources, and how these resources can transform how Halliburton works. 9,839 employees completed the full program in 2023.
