We reset our earnings power and improved margins in several key end markets. Halliburton generated over $1.3 billion of free cash flow* in 2021, demonstrating our ability to generate strong free cash flow in different business environments. Halliburton has strengthened our balance sheet, reducing gross debt by $1.2 billion during the pandemic, with another $600 million reduction in the first quarter of 2022. * Management believes that free cash flow, defined as operating cash flows less capital expenditures, plus proceeds from sale of equipment, is an important liquidity measure that is useful to investors and management for assessing the company’s ability to generate cash.

As this multi-year upcycle accelerates, we will use our international strength and leadership position in North America to deliver profitable growth and industry-leading returns. We will also build on the tangible progress we made in 2021 toward achieving our 40% reduction in Scope 1 and 2 emissions by 2035 from our 2018 baseline. And, as ever, we remain well positioned to support our customers through the energy transition as a leader in technology and innovation. Deliver Profitable Growth Internationally Throughout 2021, and despite global supply chain challenges, we served customers in more than 70 countries. In doing so, we allocated capital to the highest returns opportunities, increased international revenue and margins every quarter, and brought new drilling and formation evaluation technologies to the international markets. We also scaled our artificial lift business in the Middle East and continued construction of our new specialty chemicals plant in Saudi Arabia. We expect our international accomplishments in 2021 to set us up for continued profitable growth in 2022. Maximize Cash Flow in North America As the only fully integrated oilfield services company in North America, our strategy is to maximize cash flow in this structurally changed market, which remains the largest oil and gas services market in the world. Halliburton’s North American business in 2021 benefited from meaningful operating leverage we created early in the pandemic and expanded margins as customer activity accelerated across basins. We also have the right type of equipment for this market. We are the leaders in the high- demand, low-emissions equipment segment with our Tier 4 dual-fuel and electric fracturing solutions. As you will read in this report, our proven Zeus™ e-frac solution helps customers reduce their carbon footprint and provides unprecedented operational control and precision. The Halliburton 2021 Annual & Sustainability Report highlights our execution on each of our strategic priorities and how we will accelerate into the multi-year energy upcycle. In 2021, we delivered profitable international growth, maximized cash flow in North America, deployed new digital and automation technology while we increased capital efficiency, and advanced a sustainable energy future. We did so through a transition year that witnessed a world reopening from the pandemic and an oil and gas demand recovery accelerating across the globe. We owe our 2021 success to the work of our global team of more than 40,000 Halliburton employees. They delivered solid execution across every part of our business — safety, service quality, and financial results. You will read about that execution throughout this report. Despite the challenges of working during a pandemic with increasing complexity in global energy demand, they outperformed and delivered what the world requires — affordable and reliable energy that oil and gas provides — in a safe, efficient, and ethical manner while minimizing our environmental impact. Our 2021 financial performance demonstrates that aligning our actions with our strategic priorities allows us to accelerate cash flow generation, strengthen our balance sheet, and increase cash returns to shareholders. This execution on our strategic priorities Halliburton 2021 Annual & Sustainability ReportIntroductionHalliburton 2021 Annual & Sustainability Report Introduction 8 Accelerate Digital and Automation We advance digitalization and automation in all aspects of our business. In 2021, Halliburton 4.0 — our digital approach — accelerated the deployment and integration of digital and automation technologies within our own and our customers’ operations. As a result of increased digital adoption, we benefit from more intelligent, remote, autonomous, and environmentally friendly operations. We showcase these advancements in this report. Increase Capital Efficiency Halliburton focuses on driving capital efficiency across the balance sheet. This is consistent with our goal to deliver significant free cash flow to shareholders. Research and development and process changes allow us to build tools cheaper, lengthen their run life, and move assets to where they make the best returns. Capital efficiency also allows for our many investments in health and safety, employees, diversity, equity, and inclusion, and the communities in which we operate. Advance a Sustainable Energy Future Finally, our strategy is to advance a sustainable energy future. Our cycle of innovation includes sustainability, and Halliburton’s global resources, leading engineering, scientific and technical expertise, and more than a century of experience provide our customers with the efficient and innovative tools and services to minimize the environmental impact of their oil and gas operations. This report contains many examples of technologies that help our oil and gas customers decarbonize their legacy production base, reduce water consumption, produce less waste, and enhance efficiencies to improve project economics. At the same time, we are on a parallel path to use our existing technologies in renewable energy applications. This report highlights how Halliburton employs our technology in those adjacent markets. 2021 was the first full year of Halliburton Labs, our clean energy accelerator. We have 12 participating companies, each of whom have access to our collaborative environment in which entrepreneurs, academics, and investors work together to advance cleaner and more affordable energy. Through Halliburton Labs, companies benefit from Halliburton’s more than 100 years of industrial capabilities, technical expertise, and culture of teamwork and mentorship. Through their work at Halliburton Labs, we — and our participating companies — plan to achieve results that make a significant impact on clean energy’s future. Into the Future 2022 and beyond present enormous opportunity as the multi-year upcycle unfolds. We approach the future with enthusiasm and resolve to execute on our value proposition: we collaborate and engineer solutions to maximize asset value for our customers. We are confident that our focus on technology differentiation, digital adoption, and capital efficiency positions us for profitable growth internationally and maximizing value in North America. Halliburton 2021 Annual & Sustainability Report Introduction 9 Halliburton will evolve as energy evolves. 2021 demonstrated that to advance everywhere for everyone, the world will require oil and gas long into the future, even as it transitions to additional energy sources and builds out required value chains. Halliburton’s core competencies and service excellence will play an important role regardless of the energy source called upon to deliver the future of energy. A bold vision of the future requires a steadfast, focused, and technologically advanced energy supply and Halliburton stands ready to deliver. As we move forward, Halliburton will continue to work with our customers to provide reliable, affordable energy to all people around the world — whether in emerging or established economies. In closing, we thank our employees, our Board of Directors, and our shareholders for the important role each of you play in our success. Halliburton managed the transition from a global pandemic to the next energy upcycle because of the hard work of our employees, who deliver on our core values of integrity, safety, respect, creativity, and reliability every day. We look to the future with optimism and are well on our way to deliver strong free cash flow and returns for our shareholders. Jeffrey A. Miller Lance T.

You can find additional information about our company on our website, including detailed statements on our mission, vision, values, and our sustainability guiding principles. Our Value Proposition We collaborate and engineer solutions to maximize asset value for our customers. Values Our values are our corporate DNA, and they are the foundation for how we treat each other and every individual and entity with whom we interact. We expect every Halliburton employee to use, live by, and demonstrate these principles on a daily basis. Sustainability Guiding Principles Built on a foundation of ethics and integrity, the Halliburton Guiding Principles for Sustainability provide the framework for our operations and our future. Our Values RELIABILITY SAFETY COLLABORATION COMPETITION CREATIVITY RESPECT INTEGRITY Guiding Principles for Sustainability HEALTH, SAFETY, AND ENVIRONMENT COLLABORATION FINANCIAL TECHNOLOGY GLOBAL PERFORMANCE AND INNOVATION CITIZENSHIP TRANSPARENCY Our Mission 11 Materiality-Based Approach We continue to have open, frank dialogue with our stakeholders, including our shareholders, about environmental, social, and governance topics. Feedback from our investors, customers, workforce, and ESG rating organizations, among others, reassured us that we are focused on the right priorities, which is why there are no new changes to our ESG materiality matrix this year. This materiality matrix shows the relative weight of different topics from two perspectives. The X-axis shows how important the industry considers an issue, and the Y-axis shows the topic’s importance to our stakeholders. Our work this past year represented a continuation of the priorities we established in 2020, and we are confident in our progress toward the sustainability commitments of each material topic, as seen in the next table and highlighted throughout this report. Dow Jones Sustainability Index (DJSI) included Halliburton in the S&P Global Sustainability Yearbook 2022, which highlights the top 10% most sustainable companies per industry.

In these discussions, we use our Listen and Respond mainstay as a guiding principle. To support our outreach efforts and further our commitment to transparency, we invested in a new, robust website that we regularly update to share important information with our shareholders, customers, employees, and others. Shareholders Halliburton values ongoing, open shareholder dialogue to ensure that the Board and management have a regular pulse on investors’ views. This dialogue also provides valuable feedback on how we can continue to improve. Following our 2021 Annual Meeting, the Board recommitted to more active shareholder engagement. We enhanced shareholder communications, refreshed our shareholder presentation, opened additional availability for director video calls, and listened and responded to shareholders about possible changes to governance and executive compensation. In 2021, independent Board members offered and held off-season meetings with stewardship representatives from our top shareholders to gain a better understanding of their priorities and concerns prior to the proxy voting season. We offered these meetings to 34 of our top shareholders representing approximately 60% of our shares. Each received the opportunity to meet with Board members by video conference. For those unable to attend, we sent our refreshed shareholder presentation to each and offered follow-up. The updated materials highlighted the latest information about our Board oversight and corporate governance; executive compensation program; health, safety, and environment (HSE) performance and strategies; diversity, equity, and inclusion (DE&I) performance and strategies; and our approach to energy transition. After receiving these new materials, additional shareholders accepted the offer to meet. During off-season engagement, Board members and management conducted video conferences with 18 shareholders representing about 40% of our shares and with the two largest proxy advisors, Institutional Shareholder Services Inc. (ISS) and Glass Lewis. These included video conferences with Murry Gerber, Chair of the Compensation Committee, or Robert Malone, Lead Independent Director, and senior management. This off-season investor engagement program was in addition to routine solicitation of shareholder feedback coincident with annual and quarterly reporting, earnings conference calls, and investor meetings. Also, our senior management and Investor Relations team regularly hold meetings and conference calls with analysts, institutional investors, and ESG rating firms, among others. In 2021, Halliburton participated in 13 sell-side conferences, three non-deal roadshows, and approximately 300 investor meetings that are all part of our ongoing shareholder outreach cadence. Our senior management and directors presented shareholder feedback to the full Board of Directors for discussion. As a result of these engagements and Board consideration of investor feedback, we made changes discussed in this report, including our enhanced Board governance and 2022 annual executive incentive plan. (For more information about changes to our executive compensation, please visit Chapter G1 on Corporate Governance in this report.) Institutional Investor magazine once again recognized Halliburton in 2021 with these honors: All-American Executive Ranking as a Most-Honored Company, Best CFO, and Best Investor Relations. Customers Our business development team and product service lines (PSLs) meet regularly with our customers to understand their requirements and concerns, including sustainability topics. This input is critical to the investments that we make in research and development (R&D) for new products and services, and to improve existing solutions. To help our customers in their transitions to a lower- carbon future, we work with them to provide solutions and services that reduce their emissions. Halliburton 2021 Annual & Sustainability ReportIntroduction14 Employees With a diverse employee population representing multiple nationalities, we maintain regular employee engagement through a range of initiatives, including personal Check-Ins (Halliburton’s informal performance-management process), workshops, townhall meetings, performance feedback, employee resource groups (ERGs), and our biannual Employee Pulse Survey (EPS). These activities lead to an inclusive workplace in which employees feel their voices are heard no matter where they work. For more information about the EPS and the results of our August 2021 survey, which yielded our highest-ever response rate, please refer to Chapter S4 on Diversity, Equity, and Inclusion (DE&I) in this report. We use the information gleaned from this outreach to improve our workplace. Suppliers As a global provider of oil and gas services, we work with suppliers from all over the world and cultivate mutually beneficial, long-term relationships. We obtain feedback and ensure collaboration with suppliers on important matters, such as worker health and safety procedures, human rights compliance, and reduction of environmental impacts. Our communications with suppliers include meetings, workshops, and training sessions. Regulators We engage with government agencies and regulators that are responsible for developing regulatory standards that aim to protect the environmental, social, and economic fabric of the countries in which we operate. Our Halliburton Government Affairs group works alongside local operations management, government officials, and policymakers to provide in-depth information on our business; educate them on our technologies and products; and collaborate on issues that are important to our customers, employees, and other stakeholders. Government officials and policymakers often seek out our knowledge and experience on energy-related topics. Additionally, Halliburton supports foreign service offices, consulates, and embassies around the world as a technology and local content resource. Local Communities and Non-Governmental Organizations (NGOs) To support the global communities in which we live and work, we meet with community groups, nonprofit organizations, and NGOs to better understand their requirements and concerns. We give back to our communities through volunteer programs focused on environmental cleanup and awareness, education, health and safety, and social services. We also support community organizations through corporate donations and from our charitable foundations. Through these activities, we assist the economic and social well-being of our communities.

Halliburton 2021 Annual & Sustainability ReportGovernanceHalliburton 2021 Annual & Sustainability Report Governance 17 Board Experience and Diversity (continued) The Halliburton Board evaluates representative diversity when we consider the overall composition of our Board and its committees. This means we consider our key stakeholders such as our customers and suppliers, but also — importantly — our own workforce, which we believe to be one of the most diverse in the world, as it represents more than 70 countries and 130 nationalities. Following the addition of new board members in February 2022, more than half of our 12 directors are women or represent racial/ ethnic minorities. Halliburton announced the addition of Tobi Young and Earl Cummings to our Board of Directors. They bring a wealth of experience that includes leading roles in the private and public sector, entrepreneurship, technology, and governance. In addition, their wide-ranging roles and experience bring important perspective to our Board. ESG Oversight Enhancements Based on our commitment to provide thorough oversight of ESG risks, opportunities, and strategy, the Halliburton Board of Directors conducted a detailed analysis of our Board structure in 2021. We performed an extensive review of other Board structures and consulted with our shareholders and leading experts. The analysis found that our Board structure and oversight provide a leading model for good governance. Through the review, we also identified an opportunity for Halliburton to dedicate a committee to oversee ESG and elevated the Nominating and Corporate Governance Committee for oversight of these issues. Although the Nominating and Corporate Governance Committee oversees ESG, each committee is responsible for different aspects of ESG, as outlined in each respective charter. The Board sharpened its overall ESG oversight of the Company by focusing more time on these matters in both committee and full Board meetings, as well as in our engagements with Halliburton’s shareholders. By engaging regularly with shareholders and other outside experts to discuss sustainability topics, the Board can more effectively prioritize relevant ESG issues within our overall corporate strategy. During outreach, our shareholders endorsed this oversight structure and other governance enhancements. Below are the primary oversight responsibilities of our Board’s committees, with newly expanded or clarified responsibilities bolded: Board of Directors Nominating and Corporate Governance Committee Audit Committee Health, Safety and Environment Committee Compensation Committee • Overall oversight of ESG • Oversight and evaluation • Oversight of health, • Oversight of • Corporate Governance Guidelines • Director self-evaluation process and performance reviews • Proposing candidates for the Board • Monitoring the Board’s mix of skills, characteristics, experience, and expertise • Director compensation • Management succession planning • Political and lobbying spending of the principal independent public accountants • Internal Assurance Services and the Ethics and Compliance group • Reviewing our financial statements and our accounting systems and controls • Enterprise risk, including information security and cybersecurity* • Control structure for externally reported non-financial metrics safety, environmental, and sustainable development overall executive compensation program • HSE legal compliance • Monitoring the • HSE risk-management processes • The Company’s environmental impact, including climate issues effectiveness of our compensation program in attracting, retaining, and motivating Section 16 officers • Incorporating ESG into pay and incentive plans * The Board also enhanced its oversight of cybersecurity to include a quarterly update to the full Board of Directors. Halliburton 2021 Annual & Sustainability Report Governance 18 Energy Demand and Climate Initiatives This year demonstrated that demand for oil and gas will remain steady into the future while the transition to using alternative energy sources takes place in parallel. Halliburton and our customers play an active role in the transition to a lower-carbon future. In 2021, under the guidance of our Board of Directors, we continued our steady march forward in meeting the goals to reduce Scope 1 and 2 emissions by 40% by 2035 from our baseline year of 2018. We quantified and executed on opportunities to reduce emissions, and we are on track to meet our reduction targets. We also completed our climate risk scenario analysis, aligned with the Task Force on Climate-Related Financial Disclosure (TCFD), which we discuss in more detail in Chapter E1 on Climate Change and Emissions Reduction in this report. To learn more about our sustainable technologies and the clean energy innovations that are underway at Halliburton Labs, please visit Chapter E3 on Sustainable Energy Evolution in this report. For more information on our approach to climate change and our emissions reduction targets, please visit our Climate Change Statement on our website. Executive Compensation We integrate our executive compensation programs within our overall business strategy and management processes to incentivize performance, maximize returns, and build shareholder value. The majority of our total compensation is performance based, at risk, and long term. We combine financial and strategic metrics in our annual incentive plan, and we include relative performance measures in our long-term incentive plan. As a result of our Listen and Respond shareholder outreach effort, and with the endorsement of our shareholders, we amended our annual incentive plan to include ESG-related metrics focused on greenhouse gas (GHG) emissions and DE&I — two of our main areas of focus. ESG-related metrics will comprise 20% of the total award, with achievement of specific financial goals comprising 80% of the total award. These changes are effective January 1, 2022. For more detailed background information about the Corporate Governance and our Board of Directors, including committee structure, roles and responsibilities, and individual member qualifications, please visit the Halliburton website or view our 2022 Proxy Statement. Halliburton 2021 Annual & Sustainability Report Governance 19 G2 Enterprise Risk Management Halliburton takes a consistent, systematic, and integrated approach to our Enterprise Risk Management (ERM) program, which our Board of Directors oversees. Designed to identify, mitigate, and manage enterprise-level risks to our organization, our ERM assessment process includes a review of items that may impact company strategy, business continuity, and crisis management — among other strategic risks to the Company. Our Risk Management Sustainability Commitments • Streamline risk categories, risk identification, and risk management to ensure best alignment with Halliburton strategy and place a critical focus on what matters most. • Enhance cross-functional visibility to and collaboration among key stakeholders throughout the organization to ensure consistency, uniformity, and a strategic approach to risk assessment, identification, and mitigation. 2021 HIGHLIGHTS Enhancements to Risk Controls Global IT Infrastructure Through our risk assessment process, we continually review our risks to ensure that the Company focuses on those with the greatest potential impact to our organization. We embed any identified risks into our strategic planning for the years ahead. In 2021, as part of the risk identification phase of our assessment, our ERM group surveyed a broad group of more than 190 leaders representing different parts of the Company around the world and interviewed 29 senior- level, strategic leaders. We reported the findings to the Board of Directors’ Audit Committee, as well as to leaders who manage a part of the organization with an identified risk. Halliburton is on a strong path to advance our digital capabilities — doing so will allow us to reduce capital expenditures, enhance security, speed delivery, and improve service quality (SQ). A shift is underway to transfer applications and data from our physical data centers into a cloud-based digital platform while retaining a smaller number of network hubs that ensure secure access to cloud resources. When we complete this initiative, our physical footprint contained within these network hubs will decrease by 77% from 2020. Last year, our team transferred significant amounts of our computer and storage workload to the cloud and are on target to complete all scheduled moves by the third quarter of 2022. Cybersecurity The frequency and sophistication of global attacks on corporate IT systems containing sensitive information have increased. Halliburton takes each threat seriously and dedicates significant resources to protect our IT systems and data, in alignment with industry security standards, such as the International Organization for Standardization (ISO) 27001 and the National Institute of Standards and Technology (NIST) 800-53. In response, our Board of Directors now receives quarterly updates on cybersecurity matters, and our Audit Committee receives an annual, in-depth review. The Landmark iEnergy® platform completed a System and Organization Controls (SOC 2) Type 1 audit for security and availability. An SOC 2 Type 1 audit evaluates and certifies design effectiveness of IT system controls. The platform is currently undergoing an SOC 2 Type 2 audit, which certifies that controls are in place and working as designed. Halliburton employees share their knowledge and contribute to many industry organizations. In 2021, our Chief Information Security Officer served as board member and treasurer for the Oil and Natural Gas Information Sharing and Analysis Center (ONG-ISAC), an organization that shares intelligence on cybersecurity incidents, threats, vulnerabilities, and best practices to improve security measures within companies throughout our industry. 20 Halliburton subscribes to best-practice design philosophies for IT systems that include “zero trust,” which uses techniques such as: • Multi-factor authentication to verify the credentials of users’ identities and devices • “Defense in depth,” which puts in place multiple layers of protection • “Least privilege,” which limits the content that individual users can access Our cybersecurity team includes thought leaders who expand knowledge of their expertise. Team members contributed to the following publications for the World Economic Forum Cyber Resilience in Oil and Gas community: • Cyber Resilience in the Oil and Gas Industry: Playbook for Boards and Corporate Officers • Advancing Supply Chain Security in Oil and Gas: An Industry Analysis Through the pandemic, as employees work remotely and access our Company systems, stringent security measures are vital to protect our computing assets, networks, data, and users. A key initiative to further strengthen our security posture and improve user experience and productivity is upgrading our Enterprise Identity and Access Management solution. In addition to our own asset protection, we work with our customers to provide assurance of adequate operational technology (OT) security by participating in International Electrotechnical Commission (IEC) 62443-based assessments. Physical Security Workplace Violence Prevention Our employees’ safety is paramount at Halliburton, and the maintenance of a secure and safe workplace is one of our key priorities. Fundamental to our workplace safety is commitment to our Code of Business Conduct (COBC) and established security controls. Additionally, we regularly communicate with employees and managers on how to recognize, report, and manage threats of violence. In 2021, our Corporate Security team developed and delivered targeted training modules for key staff members to enhance our ability to respond to threats of violence. We recognize that early identification and pragmatic management of these incidents are crucial factors to reduce and mitigate the risk of violence occurring in the workplace. Halliburton 2021 Annual & Sustainability ReportGovernanceHalliburton 2021 Annual & Sustainability Report Governance 21 G3 Ethics and Compliance Respect and integrity serve as the foundation of our brand and underpin everything that we do. To maintain these core values, Halliburton has a longstanding ethics and compliance program administered by our Global Ethics and Compliance group under the leadership of the Chief Ethics and Compliance Officer and, ultimately, the Audit Committee. This program includes our COBC, Ethics Helpline, and whistleblower protections. To learn more about these programs please visit the Halliburton website. The full text of our COBC, which is available in 13 languages, can be accessed on the COBC page on our website. 2021 HIGHLIGHTS Ethics and Compliance Training Halliburton requires all employees and contractors with access to our systems to complete in-person or online COBC training every two years. We rely on our Local Ethics Officers (LEOs) to supplement this education by maintaining awareness of ethics and compliance issues on an ongoing basis and serving as a resource for our employees and contractors. We have 55 LEOs in 40 countries who model ethical behavior, answer questions, provide guidance, take reports of suspected misconduct, and deliver quarterly Ethics Moments and biweekly Ethics Topics. In 2021, LEOs conducted 2,699 presentations. This year, Halliburton provided relevant, timely, and targeted virtual ethics and compliance training to employees around the globe — and our LEOs played a critical part in this accomplishment. Our Ethics and Compliance Sustainability Commitment Conduct business with integrity, choosing the ethical course of action when confronted with challenging circumstances, promoting a speak-up culture free of retaliation, and treating our employees and stakeholders honestly and fairly. Number of Local Ethics Officers in 2021: 55 COBC Training Participants* 2019 2020 2021 43,792 45,989 50,634 * Participants include employees, contractors, and consultants who took the training during 2021.

To read about these policies and practices in greater detail, please visit the Halliburton website. We included our commitment to these principles in our COBC, which can be found on the COBC page of our website. 2021 HIGHLIGHTS Our Requirements Anti-Corruption Training Participants At Halliburton, we expect our employees to conduct business in a manner that aligns with our core values and in compliance with laws that include the U.S. Foreign Corrupt Practices Act (FCPA), the UK Bribery Act 2010, and similar applicable laws around the world. Additionally, we expect our people to compete fairly and to win business in a legal and ethical manner, which includes refraining from making unfair or disparaging comments about our competitors and their offerings. 2019 2020 2021 Employee Training 9,187 17,409 18,170 All employees with relevant job functions and those working in high-risk countries complete anti-bribery and anti-corruption training. This training emphasizes Halliburton’s core commitment to conducting business the REDWay (Responsibly, Ethically, and Diligently) in all that we do. It highlights international business relationship management and due diligence and provides guidance on ethical conduct when providing business hospitality and charitable contributions. In 2021, because of the ongoing COVID-19 pandemic, the Global Ethics and Compliance group conducted virtual training sessions to supplement our web-based anti-corruption training courses. Halliburton 2021 Annual & Sustainability Report Governance 23 G5 Supply Chain Governance Our supply chain mission is to work with suppliers who share our commitment to integrity and ethical business practices. We use set structures to screen suppliers, measure their compliance within our supply chain, and ensure they align with our mission. To learn about our Supplier Management System, along with our policies for local supplier procurement, conflict minerals, prevention of modern slavery and human trafficking, and our expectations for suppliers related to compliance and training, please visit the Supplier Relations section of our website. 2021 HIGHLIGHTS Our Supplier Conduct and Responsible Procurement Sustainability Commitment Cultivate a sustainable supply chain through the continuous improvement of internal processes, by performing proactive risk assessments and by working collaboratively with our diverse mix of global and local suppliers. Human Rights as an Essential Component of Supplier Qualification assess inherent risk in our supply chain based on country, category, and spend classification, which helps prioritize areas for detailed follow-up. Halliburton recognizes the importance of performing due diligence on suppliers with respect to slavery and human trafficking. We require suppliers to contractually commit to protect and uphold the fundamental human rights of their employees as stated in the United Nations Universal Declaration of Human Rights. We also comply with the UK Modern Slavery Act of 2015 and the Australia Modern Slavery Act of 2018. (To learn more about our compliance with Australia’s Modern Slavery Act, please visit Chapter S6 on Human Rights in this report.) In 2021, Halliburton implemented our new digital supplier management system, which includes the Supplier Lifecycle Performance (SLP) and Supplier Performance Management (SPM) modules. SLP covers all elements of supplier request, onboarding, and qualification. SPM provides a robust tool to monitor and manage supplier performance. We also developed and built new comprehensive human rights assessments into supplier qualification in SLP and performance assessments in SPM. Additionally, Halliburton uses an internal human rights dashboard to Internal Training Halliburton uses trainings from many professional training bodies focused on supply chain and procurement, including the Chartered Institute of Procurement and Supply (CIPS), the world’s largest professional body serving procurement and supply organizations with more than 200,000 procurement and supply chain professionals in more than 150 countries. CIPS conducts training on such issues as ethics, compliance, conflict minerals, and human rights awareness. Another training Halliburton takes part in is a new course for suppliers and contractors that focuses on labor rights and identification of worker exploitation. The training, developed in collaboration with the International Petroleum Industry Environmental Conservation Association (IPIECA), includes 12 interactive modules covering topics such as fair recruitment, discrimination, working hours, worker accommodation, worker grievance mechanisms, and forced labor. 24 • Create a supply chain culture based on our continuous commitment to improvement. • Deliver supplier workshops, meetings, and visits. Partnerships • Develop long-term relationships with suppliers to create positive environments for local supplier development. • Increase value for both suppliers and Halliburton in terms of relationships, communication, cost, and SQ. Additionally, Halliburton works with IPIECA and our industry counterparts to standardize the measurement and reporting of local content globally for the oil and gas industry. An example of our activities is Australia, where we are a member of Supply Nation, an organization that helps companies allocate spend to the underused indigenous business sector through their database of indigenous suppliers. Supply Nation also offers training to help companies develop their procurement policies on this initiative. Our 2021 activities with Supply Nation include: • Attending a training called First Step, which provides an overview on the relevance of allocating indigenous spend and discusses ways in which procurement organizations can increase indigenous spend. • Reporting our annual indigenous spend, which provides Supply Nation with insights to pursue ongoing advancements in the indigenous business sector. We also attended an event in the Australian Northern Territory (NT) held by the Energy Club NT to meet local vendors, including indigenous vendors, and to explore opportunities for localizing spend. One of our customers, INPEX, sponsors this event, which enjoys participation by various companies in the industry. Conflict Minerals As a member of the Responsible Minerals Initiative and in compliance with the U.S. Dodd-Frank Act, Halliburton seeks to ensure that our suppliers source minerals in an ethical manner. In 2021, we identified 3,557 suppliers as subject to the Dodd-Frank Act and contacted them as part of our Conflict Minerals campaign. We terminate relationships with any suppliers who do not cooperate with Dodd-Frank compliance requirements. Local Content Strong, established relationships with local suppliers provide Halliburton with strategic and competitive advantages for our operations while expanding the capacity and competency of national and local suppliers, stimulating local economies, and promoting positive labor practices. We work with governments and customers around the world in a legal and ethical manner to meet local content targets, and we have achieved a high rate of spend with suppliers based in the regions in which our operational activities take place. Commitment to Local Communities in 2021: 86% Percentage of Spend with Local Suppliers The three elements of our local content strategy are: processes, practices, and partnerships. Processes • Provide opportunities, contracts, and feedback to local suppliers. • Implement a functional mailbox that is always accessible to enable new suppliers to contact and present their capabilities to the local procurement team. • Visit vendor facilities every month to meet new suppliers and develop relationships with existing suppliers. Practices • Clearly define Halliburton expectations and requirements for HSE and SQ. Halliburton 2021 Annual & Sustainability ReportGovernanceHalliburton 2021 Annual & Sustainability Report Governance 25 G6 Public Policy Because the regulatory environment for the global energy industry is complex and constantly evolving, Halliburton stays engaged on public policy issues that affect our Company, operations, and workforce. To read more about our policies regarding political activities and engagement, as well as the multi-candidate, non-partisan Halliburton Company Political Action Committee (HALPAC), please visit the Public Policy section of our website. 2021 HIGHLIGHTS Greater Transparency In 2021, Halliburton published a comprehensive report (Halliburton Policies for Political Engagement) on our annual political activity. Notable highlights from this report include: • Zero corporate contributions made directly to political parties or candidates • Zero corporate contributions used to support ballot measures • Prohibitions against using corporate funds to contribute to 527 and 501(c)(4) organizations • Board oversight of the Company’s strategy for political engagement For our efforts, in 2021 Halliburton scored an 80% on the CPA-Zicklin Index. Developed by the Wharton School of Business, Zicklin Center for Business Ethics Research, this index scores corporations on the transparency and accountability demonstrated within their political engagement policies. The index uses 24 scoring elements focused on political contributions, trade associations, and political action committee (PAC) activities to calculate a raw score. Halliburton’s raw score of 56 points places us within the top 20% of all companies. In 2021, Halliburton scored an 80% on CPA-Zicklin Index This index scores S&P 500 corporations on the transparency and accountability demonstrated within their political engagement policies. Halliburton is within the TOP 20% of all companies scored Halliburton 2021 Annual & Sustainability Report Environmental 26 E1 Climate Change and Emissions Reduction E2 Environmental Management E3 Sustainable Energy Evolution Environmental At Halliburton, our work to help our customers extract oil and gas that fuels the world in a safe, reliable, and efficient manner is at the core of our business. Oil and gas are an essential source of energy and play a critical role in the energy transition. For our own and our customers’ operations, we actively work to identify ways to facilitate the evolution to a lower-carbon future with the innovation of new technologies that mitigate environmental impact. We proactively manage environmental risks, and we take measures to reduce energy use, water use, and waste generation. At Halliburton Labs, we collaborate with early-stage companies that develop clean energy technologies to help advance their products to the marketplace. Halliburton 2021 Annual & Sustainability Report Environmental 27 Our Climate Change Sustainability Commitments • Achieve a 40% reduction of Scope 1 and 2 emissions by 2035 from our 2018 baseline. • Partner with Tier 1 suppliers to track and reduce Scope 3 GHG emissions. E1 Climate Change and Emissions Reduction We lower the GHG emissions profile of our internal activities, and of our portfolio of technologies and services, to meet the goals of the Paris Climate Accord, which seeks to limit global warming to well below 2°C compared to pre-industrial levels. As a result of these efforts, we also help our customers decarbonize their operations and reduce their emission footprints. We are committed to a sustainable energy future and have work underway to improve our energy efficiency and advance clean energy development. For more information on our Company’s commitments, please refer to our Climate Change Statement on the Halliburton website. 2021 HIGHLIGHTS Sustainable Energy Priorities Halliburton has set science-based targets to reduce Scope 1 and 2 emissions by 40% by 2035 from our 2018 baseline. We have made progress on our targets by quantifying and executing on opportunities, which puts us on track to reduce emissions and meet reduction targets. Nigeria Cuts Diesel Fuel Use by More Than 58% Custom SeaQuest® and ScaleFightR Solution Cuts Emissions in the Gulf of Mexico In Nigeria, the installation of a power transformer at our facility led to a greater than 58% improvement in diesel consumption, generating cost savings as well as emissions reduction. With this change, we reduced the number of shipments and, therefore, the number of trucks on the road. The Halliburton Stim Star IV field operations team combined our SeaQuest® seawater-based fracturing fluid system with our ScaleFightR scale-inhibitor chemicals to overcome the technical challenges associated with operations in sea water and barium-rich formations. Compared to the freshwater fracturing fluids that are typically used to stimulate reservoirs and that require multiple vessels to carry barrels of fluid to the wellsite, the patent-pending combination eliminated the requirement for extra supply vessels. 28 Climate Risk Scenario Analysis Sustainability Labels In 2021, Halliburton conducted a detailed climate risk scenario analysis. A team of 24 internal cross-functional stakeholders, along with external consultants, assessed the significance of climate-related risks and opportunities, aligned to TCFD guidance. Using sustainability labels, we identify the emissions footprint of our critical products and services in the field. We expect that disclosing this information will help our customers make informed product selections and meet their decarbonization targets. We completed a systematic process for our climate risk scenario analysis: 1. Assessed the significance of climate-related risks and opportunities 2. Identified and defined a range of scenarios 3. Mapped business impacts 4. Determined potential responses The analysis considered the International Energy Agency (IEA) Stated Policies Scenario (STEPS) and Sustainable Development Scenario (SDS), as well as the Intergovernmental Panel on Climate Change (IPCC) Climate Scenario SSP3-RCP7. Our use of published scenarios that consider a range of alternative future outcomes helps to inform our understanding of climate- related risks and opportunities and supports our development of resilient strategies for a complex and dynamic future. We categorized transition risks and opportunities according to their market, policy, technology, and reputation impacts. We categorized physical risks as chronic, such as extreme heat and drought, or acute, such as hurricanes and flooding. We assessed these impacts based on a review of: • Input from climate experts and consultants • Review of relevant reports, including those from American Petroleum Institute (API), IPIECA, and Energy Workforce and Technology Council, and IEA and IPCC transition scenarios • Existing risk disclosures from suppliers, peers, and customers (CDP and other disclosures) The takeaways from our climate risk scenario analysis support our ERM process and reinforce our sustainable energy strategic priorities: Help our customers meet their goals for reducing GHG emissions As part of our organization’s digital transformation, Halliburton PSLs will work to integrate sustainability labels into digitized workflows so we can generate labels before we execute jobs and compare those labels with operational data and actual post-execution results. Access to this data will help our PSLs better understand whether opportunities exist during technology development to reduce emissions and prioritize the opportunities for our customers’ benefit. Facility Improvements to Reduce Energy Use Halliburton strives to reduce energy use in our facilities. In 2021, Halliburton reduced our global real estate footprint by more than 2%, which decreased our facilities’ energy demands. This is in addition to a 22% reduction of our real estate footprint in 2020. To meet sustainability targets and to comply with regulations, we assess newer real estate technologies and update our facilities accordingly. As part of our building maintenance, we also evaluate technologies associated with major structural elements — including heating, air conditioning, and ventilation (HVAC), insulation, and windows — to identify potential updates for more energy- efficient performance.

Typical building automation systems work in a sequence of events. They react to temperature changes and humidity, and then adjust interior spaces based on set points. Using AI, we can examine whether the automation system can predict what it must do to lower energy consumption while improving comfort in buildings. Select buildings at our corporate headquarters serve as a pilot location for this test. Solar Power As part of an ongoing rooftop solar initiative that includes four major projects in Singapore, India, and California, Halliburton commissioned two new solar projects in Malaysia and Colombia in 2021. At our manufacturing facility in Johor, Malaysia, Halliburton executed a 25-year solar power purchase agreement (PPA) in the first quarter of 2021. We installed and will maintain 2,247 fixed-tilt, roof-mounted solar panels totaling 999,915 kilowatt peak (kWp). This is the largest size solar array that the local regulations permit. The solar array will produce 1,000 megawatt hours (MWh) of electricity annually. It has offset approximately 22% of the facility’s usage from August to December, 2021. Additionally, at our field camp in Barrancabermeja, Colombia, Halliburton executed a 10-year solar PPA in the fourth quarter of 2021. We installed and will maintain 278 fixed-tilt, roof-mounted solar panels totaling 99 kWp. The solar array will produce 228,000 kWh of electricity annually, offsetting approximately 49% of the facility’s current usage. In 2022, we expect to explore similar projects elsewhere in Colombia, as well as in Mexico and Brazil. Energy-Efficient Lighting In North America, we are nearing completion of LED lighting retrofits at 13 large facilities, which will reduce carbon emissions from lighting by 63% per year. At our Añelo Field Camp in Argentina, we completed LED renovations in our offices, then met the need for additional lighting along pathways and parking areas with LED lighting towers that are powered by solar panels and battery storage thereby avoiding almost 40,000 kWh in a year from the electrical grid. We are evaluating another 42 Halliburton sites in North America, Europe, Eurasia, and Sub-Saharan Africa for potential completion of retrofits in 2022. Green Electricity As we establish new electricity supply contracts, Halliburton purchases green electricity from the grid when available and feasible. In 2021, we signed two three-year agreements for 100% green electricity with 12 accounts in Alberta, Canada, and two accounts in Pennsylvania in the U.S. Halliburton 2021 Annual & Sustainability ReportEnvironmentalHalliburton 2021 Annual & Sustainability Report Environmental 30 E2 Environmental Management We use the Halliburton Management System (HMS) to manage environmental risks and identify opportunities to mitigate our environmental impact. It encompasses a comprehensive set of policies, business practices, and procedures for how we work, including how to reduce our energy use and GHG emissions, improve water quality and conservation, use chemicals in environmentally safe ways, decrease waste, protect the quality and biodiversity of our environment, and manage environmental practices in our supply chain. To read about the HMS in more detail, please visit the Halliburton Management System section of our website. 2021 HIGHLIGHTS Our Environmental Improvements Sustainability Commitments • Establish and achieve waste-reduction targets in our major facilities. • Create water-use-improvement plans in our major facilities located in water-stressed areas. Facility Certifications Environmental Incidents The HMS, along with all associated processes and procedures, conforms to industry-standard certification programs, including ISO 14001 and API RP 75. Individual Halliburton facilities and PSLs are externally certified to ISO 14001, based on business requirements. In 2021, 73 Halliburton facilities held ISO 14001 certifications, representing 17% of our active global properties. The majority of reported environmental incidents are spills that occur at Halliburton facilities and field locations. In 2021, we had no significant environmental noncompliance spill incidents and no significant environmental fines. Recordable Environmental Incident Rate Environmental Awareness Training Incidents per 200,000 hours worked  In 2021, we initiated a campaign to raise awareness of environmental compliance and stewardship. We provided our workforce with a training module focused on environmental compliance and reporting. The campaign aimed to ensure that all employees, regardless of their roles, understand their impacts on the environment and their stewardship responsibilities. 2019 2020 2021 0.03 0.02 0.02 Halliburton 2021 Annual & Sustainability Report Environmental 31 Chemical Stewardship We responsibly manage the environmental risks posed by our chemical products and services over their lifecycle. To improve our chemical stewardship processes and systems, the Global Chemical Stewardship (GCS) team collaborated with internal users to launch a new workflow application, the Chemical Request Management System (ChRMS, pronounced as “charms”). The new system allows users to track the progress of requests for compliance purposes. It also helps us balance the protection of intellectual property with the rights of the chemical manufacturer. Together, in one centralized system and with incorporated global master data, these features deliver a higher level of compliance assurance and facilitate smoother workflows for our personnel. In addition, the integration includes our Safety Data Sheets (SDSs) with information about the safe use of chemicals. Our SDSs are available in 37 languages in more than 70 countries and 20 jurisdictions. We keep all information related to global chemical stewardship updated and available to users around the world. The development of ChRMS aligns with our Halliburton 4.0 approach to digitize the value chain and create internal efficiencies. Sustainable Water Initiative The 3R initiative at liquid mud plants aims to accomplish the following: Reduce disposal volumes along with dilution requirements Reuse non-aqueous fluids in other applications and extend their longevity 3R Repurpose waste fluids in applications in which fluid quality is less critical We work with customers to “3R” all fluids to the fullest extent possible — even proactively cleaning, blending, and reusing most feedstock to help achieve habitual environmental conservation. Not only does this practice save water, but it can prevent some of the emissions associated with the manufacture, transfer, and mixing of new fluids and their components. Halliburton 2021 Annual & Sustainability Report Environmental 32 Water and Effluents We work with our customers to reduce their water usage. Although customers purchase and control the water they use at hydraulic fracturing sites and at wellsites, we provide solutions to assist customers with water usage. Our reported water-usage data includes water used at Company-owned or Company-leased locations, except those locations that include water usage in the lease, and covers our facilities in the U.S. and Canada and most global facilities. Many of our locations have implemented water-reduction and water-recycling projects, particularly those in water- stressed areas. Water Withdrawal Cubic meters 2019 2020 2021 2,351,678 1,345,507 1,478,921 UK In Scotland, the Aberdeen Maintenance and Sperry Drilling departments have tanks that store water previously used in function testing activities until the water can be reused. This eliminates the requirement to use fresh water for every test. Thailand Our water treatment system cleans and separates oil discharge from water. The Thai government allows Halliburton to sell the water to a recycling company. Argentina At the Añelo Field Camp, we built a water-treatment plant that we completed in January 2022. The plant enables us to reuse 88% of the wastewater generated in our washbays. 33 Waste Reduction At Halliburton, we develop waste minimization and management plans to reduce the amount of waste generated at our offices, workshops, field camps, manufacturing facilities, and wellsites under our control. Our waste-generation data covers all U.S. locations, all manufacturing locations, and any non-U.S. location that has a building footprint larger than two acres (8,092 m²) and that houses those activities identified as having the largest potential for waste generation. As we look to 2022, we are in the process of standardizing and digitizing waste-reduction tools and resources across our facilities to identify waste-reduction opportunities and effectively execute on them. Waste Disposal Metric tons 2019 2020 2021 294,123 342,306 349,843 Argentina In 2021, our collaboration with waste-management providers has resulted in the recycling of 37% of our total solid waste output. We send these materials — which include wood, pallets, cardboard, paper, and large bags — to waste-treatment facilities for processing as raw materials and conversion into other products. UK Our waste contractors installed skids that route hard plastic materials for recycling, in addition to softer plastic materials from packaging. Halliburton 2021 Annual & Sustainability ReportEnvironmental34 UK and Africa In Scotland, we diverted 32 metric tons of wood waste including dry timber, used crates, pallets, and solid wood from a biomass plant to a local charity in Aberdeenshire, Wood RecyclAbility. This organization repurposes wood waste to make many beautiful, high-quality products that it sells to the public, such as furniture, various household products, and bespoke products. However, what makes this organization truly special are the opportunities that it provides to its trainees, who are adults with a range of additional support needs. Their work with Wood RecyclAbility gives them a purpose, life skills, wood-working skills, and, in some cases, has led to their full-time employment. In Africa, we repurposed wood from original packaging to build new boxes for material exportation. Brunei Halliburton worked with a local recycling company to convert paper waste into toilet paper. We collect non-confidential paper waste from our Brunei facilities — including from our offices, workshops, bulk plants, vessels, and rigs — and store them at designated recycling bins. On a monthly basis, recyclers collect the material and then transform it into a 100% recyclable toilet paper product. In 2021, Halliburton recycled 300 kilograms of paper. Halliburton 2021 Annual & Sustainability ReportEnvironmental 35 Biodiversity Our commitment to environmentally sound and sustainable business practices includes minimizing disturbances to the land where we develop our offices, field camps, chemical facilities, and service centers. To support this commitment, we conduct proper environmental due diligence and permitting when establishing new facilities and ensure regulatory compliance through the life of each facility. Additionally, we recognize the inherent value in threatened lands and species, and we evaluate programs and methods to protect sensitive habitats around our locations. Our employees took part in many biodiversity initiatives at our facilities around the world. We planted trees at many of our global sites, including our Coca Base in Ecuador, Añelo Field Camp in Argentina, Saihat facility in Saudi Arabia, Malaysia facilities, and the forests in Cabinda, Angola.

Tier 4 Engines and E-Frac Halliburton has the largest fleet of Tier 4-compliant engines — both diesel and dual fuel — in operation in the U.S. and the Gulf of Mexico. Tier 4 is the U.S. Environmental Protection Agency’s (EPA) strictest regulation for nitrogen oxides and particulate emissions. Our Tier 4 dual-fuel engines enable operators to use natural gas instead of diesel fuel as the majority of their fuel source. The option to use field gas minimizes flaring, which reduces emissions and is less costly for our customers. Because of the way that Halliburton developed our technology, we can convert our diesel engines to Tier 4 dual-fuel. North America Industry Leader in EPA Tier 4-Compliant Diesel Engines Percentage of Tier 4 Diesel Engine Penetration 2019 2020 2021 Hydraulic fracturing pumping equipment (HHP) that meets Tier 4 compliance for non-road diesel engine emissions 52% 56% 53% We also offer all-electric fracturing capabilities using our second-generation Zeus™ electric pumping unit, ExpressBlend™ electric blending system, eWinch™ electric wireline unit, and an electric Tech Command Center. All this equipment can run on electric power, generated using natural gas or taken directly off the grid, for the lowest possible emissions profile. This solution also allows for additional electrification of fracturing locations, such as lighting and water transfer. An active focus on our e-frac capabilities is underway. In August 2021, Halliburton announced the industry’s first deployment of an advanced e-frac solution with Chesapeake Energy Corporation. The project combines our all-electric fracturing spread with VoltaGrid’s power- generation system. By using this technology in its local field gas network, Chesapeake Energy reduced emissions by 32% and applied more than 25 megawatts of lower-carbon power generation without sacrificing operational performance or reliability. This project is a major step forward in our customer’s goal of achieving net-zero emissions. Halliburton 2021 Annual & Sustainability ReportEnvironmentalCementing Products The Cementing PSL has two main focus areas: to reduce the carbon footprint of the solutions that we provide to our customers and to stop fugitive gas emissions for the life of a well. 39 NeoCem™ IsoBond™ Obex™ The NeoCem™ cement system reduces the amount of Portland cement in the wellbore isolation barrier by an average of 40% by mass Portland. (Portland cement accounts for the majority of the carbon footprint in a cementing job, as its manufacture and transport releases air pollutants.) Our Obex™ family of compression- set, mechanical packers (Obex GasLock™ packer, V0 rated; Obex IsoLock™, V3 rated; and Obex EcoLock™, V6 rated) enhance well integrity and therefore prevent fugitive gas emissions. By offering a powerful mechanical barrier, Obex™ packers improve zonal isolation and mitigate sustained casing pressure to avoid failures leading to annular gas migration. The IsoBond™ cement system prevents sustained casing pressure over the life of a well, which helps improve well integrity and stop fugitive gas emissions from releasing into the environment. The system accomplishes this through: • Low fluid loss and fast transition times to prevent the flow of gas through cement as it sets. • Enhanced shear bond, in which the ability of the cement to adhere to steel casing improves by as much as 40% compared to other cementing systems. • Reduced cement permeability by more than 70% compared to other cementing systems, which prevents gas and other wellbore fluids from migrating through the cement after it sets. Halliburton 2021 Annual & Sustainability ReportEnvironmentalBaroid Production Solutions 40 BaraHib™ Gold WaterWeb® BaraHib™ Gold high-performance water-based mud eliminates the requirement for the containment, transport, and treatment of oily cuttings onshore. Fluid makeup includes approximately 15% industrially produced materials (except water and barite) by volume, compared to approximately 60% in a typical non-aqueous fluid. With trackable inhibitor technology, BaraHib™ Gold fluid also has a longer run life than typical water- based fluids. Our WaterWeb® conformance service gives operators the ability to lower the treatment and disposal costs of produced water, along with the associated environmental impacts. To accomplish this, the WaterWeb® service uses a polymer chemistry to impede water flow while enhancing hydrocarbon flow to the wellbore in any type of reservoir — including sandstone and carbonate formations. This technology absorbs into the rock surface and creates resistance that holds water back while allowing oil and gas to pass freely, decreasing water permeability by more than 90% with little to no damage to hydrocarbon permeability. By reducing the water column, the WaterWeb® service improves the natural lift to residual oil and gas. It also helps prolong and sustain production by enhancing reservoir drainage. As an example of this technology’s capabilities, Halliburton deployed the WaterWeb® service in an offshore carbonate reservoir, where it reduced the water cut by 22% and increased hydrocarbon production to more than 600 barrels of oil per day. 95% regained oil permeability 97% reduction to water permeability 600 400 380 d m , y t i l i b a e m r e P e v i t c e f f E 16 Oil Water Before treatment After treatment Halliburton 2021 Annual & Sustainability ReportEnvironmental Halliburton 2021 Annual & Sustainability Report Environmental 41 Reduction in Battery Use To improve the sustainability of operations, Halliburton aims to eliminate the use of lithium batteries in our downhole tools. Batteries require complex logistics and safety precautions, as well as recycling. The development of solutions to generate downhole power or to continuously provide power from the surface will make a step change toward reducing our environmental footprint. Because of this, many of our PSLs, including Sperry Drilling and Production Solutions, focus on technology development that does not rely on battery power. As an example, a downhole generator powers our iCruise® rotary steerable system, removing the batteries that we used in our previous generation of rotary steerable technology. One of the design goals of our new iStar™ intelligent drilling and logging platform was to reduce the number of downhole batteries that we used. In 2022, we will deploy an additional turbine-based generator to enable further reductions in battery use. Our SPECTRUM® FUSION real-time hybrid coiled tubing services integrate fiber optic and electric communication and power to eliminate battery use. Doing so results in operations not limited by power or time constraints. The system also combines intervention and diagnostic capabilities and is fully compatible with mechanical and wireline tools. This unlimited flexibility lessens logistical constraints. Additionally, we have invested in a company that produces ultra-capacitators, a rechargeable solution that delivers the power required for our challenging downhole applications. 2021 Technology Sustainability Matrix Additional portfolio items can be seen on Halliburton.com. e t i u f l l i s G H G / s n o s s m e e v i s - n o e p o e p f o r e b m u n / b o j f o n o i t a r u D s t n e d c n i i y t e f a s r o f l a i t n e t o P i t i g u f / r i a o t i s n o s s m E i e s u l e u f l i s s o F d e s u y t i c i r t c e E l d e c u d o r p r o d e s u r e t a w f o e m u o V l m r a h r o s u o d r a z a h f o e m u l o V d e s u s l i a c m e h c / s l a i r e t a m d e r i u q e r t n i r p t o o f / e c a p S 42 i n o s u r t n i l a u s i v / r o d o / e s o n i : e c n a s u N i s t n e m e r i u q e r g n i t a o C s k a e l r o s l l i p S d e c u d o r p e t s a w s u o d r a z a h - n o n f o e m u o V l d e c u d o r p e t s a w s u o d r a z a h f o e m u o V l s t c a p m i n o i t a t r o p s n a r T l e u f l i s s o f f o d a e t s n i y t i c i r t c e l e s e s U s e c r u o s y g r e n e e b a w e n e r l s e s U y t i l i b a r u d r e h g h / n a p s e f i l i r e g n o l a s a H e l c y c e r r o / d n a e s u e r o t y t i l i b a s e s a e r c n I e f i l f o d n e t a t c u d o r p e h t f o t r a p r o l l a l a i r e t a m d e l c y c e r i s n a t n o C s l l e w f o g n n o i i t i s o p r e t t e b s e b a n E l i g n d n a t s r e d n u r i o v r e s e r s e v o r p m I y t i r g e t n i l l e w s e v o r p m I s d e l i f e r u t a m n i s k r o W ARTIFICIAL LIFT Reduction or Elimination Improvement GeoESP® Tiger Shark III® BAROID BaraECD® BaraHib™ Gold BaraXcel™ CEMENTING AirGlide™ Asset Light-Remote Control Silos Autonomous Cementing Operations IsoBond™ Obex™ Tuned® Defense™ E Cement Spacer WellLife® COMPLETION TOOLS eCompletions™ Clariti® SmartWell® eMotion® MultiLateral FlexRite® SmartWell® Fuzion™ DRILL BITS & SERVICES Articulating Gauge MULTI-CHEM APX™ — Analyzing Performance eXecution Ferrogone™ FeS Inhibitor FightR™ LX-18 Triple-Combo Inhibitors PRODUCTION ENHANCEMENT Dual Fuel Tier 4 Zeus ™ PRODUCTION SOLUTIONS HalKleen™ SafeGrip™ WaterWeb® TESTING & SUBSEA Single Trip Perf & Surge WIRELINE & PERFORATING RTRAC StrataXaminer™ Halliburton 2021 Annual & Sustainability ReportEnvironmental 43 Digital Transformation Halliburton deploys digital technology across all business lines and geographies to improve efficiencies and outcomes. Many of these capabilities reduce GHG emissions through optimization and efficiencies and provide high-quality data for enhanced decision-making and continuous improvement. Digital unlocks the potential to structurally lower costs, shorten time to first oil, increase efficiency in exploration and production, and enhance performance across the entire value chain. In 2021, the Company made great strides in our digital transformation by developing, deploying, and maturing Halliburton 4.0. Well Construction 4.0: Digitally Transforming the Well Construction Lifecycle With digitally enhanced well construction, we reduce costs and planning time and optimize well design and placement to improve drilling performance for a safer, more productive well. Well Construction 4.0 incorporates all of Halliburton’s digital technologies and allows integration and collaboration between our well engineering applications, such as Digital Well Program® and Digital Well Operations, as well as any third-party applications that an operator or contractor may use. These technological advances enabled us to reduce well planning and design time by up to 80% in the North Sea. Well Construction 4.0 automates many drilling processes. In a mature field in the Middle East, Halliburton improved drilling performance and shortened drilling time by 43% by integrating our Cerebro® In Bit Sensing, Logix™ Automated Drilling Solution, N-Flow™ 325 filter cake breaker, Pason AutoDriller, and project management services. Additionally, with our remote operations, Well Construction 4.0 helps reduce the number of people required on-site. For the first two sections of a job at an offshore rig in Southeast Asia, Halliburton decreased the number of people at the wellsite by 21%, which also reduced helicopter rides and international commercial flights to the rig. Halliburton 4.0 In 2021, Halliburton 4.0 accelerated our digital approach over the well lifecycle including subsurface, well construction, reservoir and production, and our own enterprise. Our deployment of software, hardware, AI, machine learning, and sensors gives us access to more data and operational insight than ever before. This data allows us to improve project planning, design, and execution; monitor and optimize operations in real time; enhance decision-making; shift to automated controls and remote operations; make data more accessible to all business units; and advance data storage and data analytics capabilities — all while enabling a more collaborative, connected workforce. Halliburton 4.0 increases efficiency, saves costs, and mitigates health and safety risks associated with manual labor. It also reduces our environmental impact through the elimination of paper waste and the reduction of personnel required to work at wellsites, which means fewer emissions associated with transportation, lodging, and sustenance on both land and offshore settings. Launched in the first quarter of 2021, our new cloud-based platform, Real-Time-as-a-Service (RTS), uses modern digital technology to stream real-time data to all employees and customers who have subscribed to these feeds and are authorized to receive them. A customer in Norway, the first operator to adopt RTS, uses the platform to monitor six offshore rigs. In the customer’s experience, RTS is 83% faster than our legacy real-time system, with uptime reliability of nearly 99.9%. Equally important, RTS is less energy intensive than its predecessor, relying on cloud computing that can be scaled up or down based on consumer demand. As a result of using RTS, Halliburton retired a number of on-premise data centers that had dedicated services and reduced personnel required to keep the legacy real-time system functional. Our goal is to convert 100% of our real-time requirements to the RTS platform in the first half of 2022.

Halliburton 2021 Annual & Sustainability ReportEnvironmental44 Halliburton Landmark To support Halliburton 4.0, Halliburton Landmark offers a suite of geoscience software products that enable our customers to explore and produce hydrocarbons. In 2021, Halliburton shifted Landmark products further into the sustainability space. Here are a few examples of our products that support the world’s energy transition: Neftex® PROSPECT software, which we developed in 2021 and will launch in the first quarter of 2022, supports critical mineral exploration. Electrification of transport and industrial processes is a key component of global decarbonization ambitions. However, this initiative requires a vastly increased supply of metals and minerals for success. Renewed investment in discovering additional resources will be the key to meet this demand. Landmark adapts proven oil and gas exploration workflows to aid in the hunt for minerals that are critical to the energy transition. Storage of carbon dioxide (CO2) in ancient rock strata is set to become a major contributor to emissions reduction. We can identify suitable aquifers for this purpose by using a similar approach to how we uncover hydrocarbon-bearing strata. With Neftex® Predictions and DecisionSpace® 365 software, Landmark adapts E&P workflows to consider the parameters that are important for safe CO2 storage, identify suitable aquifers, screen areas for further investigation, and model them using technologies that we developed to understand the injection and migration of captured CO2. Our technology helps customers answer critical questions such as: • Where can we store CO2? • How much CO2 can we inject, and can we inject CO2 at a sufficient rate? • Can we store it safely? • What is a site’s storage capacity over its lifetime? • Will the CO2 remain in the geological storage tank over time without leaking? We also focus our efforts to enhance our iEnergy® platform, the industry’s first hybrid cloud environment dedicated to E&P. By using machine learning, we can better manage and mitigate carbon emissions from our operations. For more information on Landmark, please visit the Landmark page on our website. This database is included in Neftex® PROSPECT software. Areas in color denote when Earth’s tectonic features were active. Because many critical minerals are found in zones of active tectonism, this information can help to identify areas for closer attention in the search for specific minerals. Halliburton 2021 Annual & Sustainability ReportEnvironmentalHalliburton 2021 Annual & Sustainability Report Environmental 45 Support for Renewable Energy Sources In addition to using our digital capabilities, Halliburton applies our existing technologies to the renewable energy space for a greater environmental impact. Carbon Capture, Utilization, and Storage Halliburton actively participates in the carbon capture, utilization, and storage (CCUS) industry, and has developed technologies to support carbon transport and storage projects. Our capabilities include geological storage site selection and development, in addition to well repurposing, construction, and monitoring, and pipeline and subsea construction and maintenance. In 2021, Halliburton applied a unique, machine learning- based 3D model for a Japanese company to estimate the availability of pore space over large areas for CO2 storage. This model increased operational efficiency, with a fivefold reduction in time spent compared to conventional approaches, along with increased accuracy. Geothermal For decades, Halliburton has offered our advanced technologies and experience to customers developing complete geothermal solutions around the world. Our products and services address every aspect of developing a geothermal energy production facility, including project management, drilling, cementing, fluids, logging, completions, stimulation, and geofluids transfer. Geothermal energy demand has expanded to more shallow-source, lower-heat applications for heating and cooling. For electricity generation, the geothermal market has expanded to deeper, higher-heat sources. Although these geothermal sources are much more efficient in generating electricity, they require advanced geothermal systems to overcome technical challenges, and Halliburton is working to service these emerging markets. In Indonesia, which is the world’s top geothermal market, Halliburton has supported geothermal activity for more than 30 years. In this time, we have drilled and produced more than 220 wells, and completed approximately 40 wells with Halliburton Project Management’s Integrated Services. In 2021, Halliburton continued to contribute to the Sarulla Geothermal project. For this project, we have worked with a market leader for more than 15 years to provide drilling and cementing services in the development of this clean, renewable energy source. During this time, we helped our customer produce clean electricity from geothermal wells safely, efficiently, and cost-effectively, and enabled a larger number of wells to produce from a single pad for less environmental impact. 46 Halliburton Labs Halliburton Labs gives early-stage, clean-tech companies access to our world-class facilities, technical and scientific experience, and business network.

It also included the physical migration of content and the classification of documents to help employees locate them in a standardized and efficient manner. The benefits of the new platform include: • Improved search capabilities • Enhanced reporting and analytics • Easier access to documents You can find more details about our HMS on the Halliburton Management System section of our website or in Chapter E2 on Environmental Management in this report. At Halliburton, we perform activities every day that carry inherent safety and SQ risks. In response, Halliburton implemented an improved digital risk management process in 2021. In addition, we enhanced our risk management process workflow and deployed new tools such as our “5 Checks To Go” process. and controls then auto-populate on a core job safety analysis. After the team completes the work, they can share lessons learned with the organization. Overall, this results in a more effective process that we publish and share with the organization to increase safety and SQ. Under the revised risk management process, frontline leaders and teams assess documented HMS processes by using our risk assessment methodology. We identify, remove, or mitigate risks at the planning stage, which gives our frontline teams the ability to focus on identifying and addressing operational variabilities. When personnel create a risk assessment, they can assign actions to the risk assessment team or to the frontline team. These risks We also developed web-based training courses for all frontline employees, supervisors, and leaders in critical roles. By the end of 2021, 94% of personnel completed the risk management training module. In 2022, the transition will continue with additional training and coaching to support process consistency and further our project success.

In 2021, the number of SWA observations increased. Health and Safety Awareness and Training Programs Halliburton offered 638 health and safety training courses to our employees, who completed 705,739 total hours of training in 2021. To ensure that learning continued in a safe environment and that employees developed critical competencies despite the ongoing pandemic, we continued to transition to virtual training through our Learning Management System. In addition to training, Halliburton reinforces our safety culture through active safety awareness communications and targeted campaigns. As an example, last year all regions conducted campaigns highlighting hand and finger safety — one of the most common hazards in our industry. We maintained a heightened awareness of hand and finger safety through communications that included safety meetings and structured hazard hunts. Lessons Learned and Incident Investigation Incidents pose the biggest potential risks to our people. That is why it is important to focus on learning from each incident. We are fortunate that, at Halliburton, we value the opportunity to learn from and investigate incidents to avoid repeat occurrences and to support continuous improvement in our policies and practices. In 2021, Halliburton focused on two areas: 1. An investigation process that we manage through a tiered severity model, which ensures that we assign the appropriate level of support and management oversight based on the severity of the safety incident and that we allocate our resources in the smartest, most efficient way 2. A centralized, Company-wide Lessons Learned platform for sharing high-level alerts and learning opportunities throughout the organization FACILITY CERTIFICATIONS IN 2021 Certifications Number of countries with API Q1-certified facilities Number of API Q1- certified facilities Number of countries with API Q2-certified facilities Number of API Q2- certified facilities TOTAL 6 16 14 27 HSE Recognition Introduced in 2020, our HSE Recognition program highlights the efforts of our people to advance improvements in HSE performance. This biannual award highlights the outstanding practices that employees share across the organization. Here is an example of one of the 2021 initiatives that we recognized: Zero HSE Incidents in Mexico for Major International Oil Company Through PSL collaboration, our team decreased the number of personnel on offshore platforms and vessels. Use of the management of change process with established roles and responsibilities enabled the team to achieve zero HSE incidents. 55 Colombia: HSE Win for Wireline & Perforating and Drill Bits & Services PSLs Canacol Energy Colombia SA deemed Halliburton an outstanding supplier for formation evaluation work completed during the first two quarters of the year. We introduced Cerebro® in-bit sensor technology during the intermediate and production phases of an exploratory campaign. Not only did the customer identify potential hydrocarbon reserves and increase production, but Halliburton also executed the work with zero HSE recordable incidents. Trinidad: Pipeline & Process Services PSL Receives the Shell Goal Zero Hero Recognition This customer-initiated award recognizes personnel who exhibit exemplary behaviors in identifying and mitigating risks and potential hazards. For this project, Halliburton purged the topside platform to displace hydrocarbons to below the lower explosive limit to enable mechanical work to take place. To complete the job safely and efficiently, the team completed comprehensive toolbox talks; proactively engaged all personnel involved, including customers and third parties; and explained the job steps and the associated hazards, such as nitrogen oxide asphyxiation, cryogenic temperatures, and pressurized and flammable gases. Global Advances in Reducing Exposure to Radioactive Materials Objective 1: In 2020, the Production Enhancement PSL set a goal to remove 100% of radioactive densometers from North American operations and 80% from international operations to reduce exposure to hazardous materials when capturing density measurements. We are well on track to meet our target and, as of today, we have reduced exposure by 97% in North America and 59% internationally. Objective 2: Implement a sustainable process to ensure the timely disposal of radioactive sources with low levels of activity and usage, which will reduce personnel risks. In 2021, Halliburton has disposed more than 700 radioactive sources.

Our benefits package offers a wide array of programs and services, from comprehensive medical insurance, retirement accounts, and income protection while on disability, to paid time off, emergency childcare, and third-party discounts. In 2021, we enhanced our benefits offerings for U.S. employees and their eligible family members to improve their healthcare experience and to help them better plan for healthcare expenditures. These additions to our benefits package, which will go into effect for the 2022 plan year, include: Accident Insurance — This policy complements the coverage of primary medical insurance. This policy pays employees or eligible family members a lump sum if they incur an injury resulting from an accident to help cover the costs of medical treatment. Hospital Indemnity Insurance — If an employee or one of their eligible family members is admitted to a hospital — for either planned or unplanned reasons — then they are eligible for payment to help cover those costs. Halliburton offers two levels of coverage via MetLife: low ($10,000 maximum benefit) and high ($20,000 maximum benefit). Critical Illness Insurance — This policy complements the coverage of primary medical insurance by paying employees or eligible family members a lump sum to help cover treatment costs if they are diagnosed with one of the specific illnesses listed in the policy’s certificate. Halliburton offers two levels of coverage via MetLife: low ($10,000 maximum benefit) and high ($20,000 maximum benefit). 57 Enhancements to Benefits (continued) Expert Medical Opinions and Health Plan Navigation. Through our partnership with 2nd.MD, we can offer employees and their families additional support when they need it most: • Expert Medical Opinions — When faced with major changes in health status, or when there is a new diagnosis or treatment plan that includes surgery, employees can consult with world-renowned medical specialists within a few days via 2nd.MD. This gives employees the second opinion they require to make informed, confident healthcare choices. • Health Plan Navigation — Nurses at 2nd.MD help employees and their families find high-quality care within the employee’s benefits plan. This includes the identification of providers who are local, in network, and highly recommended. Tobacco Cessation Program — Halliburton transitioned our tobacco cessation program to a new partner, Well onTarget, to provide a more clinical and consultative approach to help our employees quit using tobacco products. This program offers more tailored support that is integrated within our U.S.-based medical plans, enabling employees to seamlessly transition from their tobacco cessation journey to other services, as required. In 2021, as a testament to their positive employment experience with Halliburton, we saw more than 2,800 former employees join the Company. In 2021, we hired employees in 60 countries with 54% of employees hired outside of the United States Employees represent 130 nationalities worldwide We work in more than 70 countries 92% of our workforce is local 59% improvement of females in science, technology, engineering, and math (STEM) roles over the last decade WE ARE ONE OF THE MOST DIVERSE COMPANIES IN THE WORLD 86% of our management is local 74% of our region and country vice presidents are from the regions they support Racial diversity in management positions improved from 2020 by 13% (U.S. staff only) Halliburton 2021 Annual & Sustainability ReportSocialHalliburton 2021 Annual & Sustainability Report Social 58 Prioritization of Mental Health Over the last two years, the public health crisis caused by the COVID-19 pandemic has created and exacerbated many hardships for millions of people around the world. During the first year of the COVID-19 pandemic, employees cited mental health issues — such as depression, anxiety, fatigue, grief, and bereavement — as their major concerns, second in importance only to financial concerns, via employee surveys. With the pandemic persisting for nearly two years, our workforce continues to grapple with these issues. Halliburton has worked diligently to address these emergent concerns by increasing access to our Employee Assistance Program (EAP) globally. Our EAP offers confidential help and support to employees — at no cost to them — for a range of personal and professional challenges. Between 2020 and 2021, Halliburton expanded access to EAP services from six countries — the U.S., the UK, Canada, Papua New Guinea, New Zealand, and Australia — to an additional 37 countries across Latin America, Africa, the Middle East, and the Asia-Pacific region. Our in-house EAP team is in discussions to further expand the EAP throughout Europe and Latin America. Throughout the pandemic, the Halliburton EAP team has maintained a monthly web series called Lessons for Life that feature experts who address a variety of topics related to mental health. In 2021, presentations covered topics such as Let’s Talk Mental Health, Finding Hope in the Midst of Loss, Effective Communication, COVID-19 and Substance Abuse, and Estate Planning in the Wake of a Pandemic. Halliburton expanded other mental health initiatives around the world as well. We increased our output of mental health content, which includes: • Mental Health First Aid training and certification programs in the UK and the U.S. • Quarterly EAP newsletters that we distribute in multiple markets to raise mental health awareness and engagement globally • Global mental health campaign for World Mental Health Day in which we delivered consistent messaging globally to all employees to raise mental health awareness Increase in Access (by Number of Employees), From to North America: 2 countries Latin America: 2 countries Europe / Africa / CIS: 15 countries Middle East / Asia: 24 countries Australia In September 2021, Halliburton launched R U OK? Day — a national program in Australia to raise awareness of suicide prevention — to encourage employees to check in with their family members, friends, and colleagues to inquire about their well-being. Throughout the country, we held morning teas that featured video messages from our area manager. During the teas, employees discussed mental health and had the opportunity to share personal stories. Each week, we gave toolbox support resources about mental health to our crews. Additionally, we organized weekly Zoom webinars on mental health awareness that were led by health professionals, and we created a Yammer page to create a sense of community across this region, in which we regularly share mental health tools and resources. We also introduced mental-health first aiders in our Australia locations. Halliburton 2021 Annual & Sustainability Report Social 59 The Halliburton Family An important element of our Company culture is that we care for and help each other, which is apparent during times of crisis. A strong example of how we assist our people is the Halliburton Disaster Relief Fund. When a natural disaster occurs, the Disaster Relief Fund may be activated. The fund distributes grants to employees who have been impacted by natural disasters such as floods, hurricanes, tsunamis, earthquakes, fires, or tornadoes. On August 29, 2021, Hurricane Ida struck Louisiana as a Category 4 hurricane. This storm ranks as the second- most-destructive hurricane in recorded history to hit the state. To provide relief to our employees who were impacted by this powerful storm, our Executive Committee approved the use of the Disaster Relief Fund. The fund provided a wide range of support for impacted employees, including: • Distribution of $163,000 in grants to employees who experienced significant losses resulting from the hurricane • Payment for hotel accommodations totaling more than $80,000 • Food drives • Volunteers on location to assist employees and families • Donations of generators and other critical supplies including gas, water, clothing, and diapers Employees Choose Halliburton Colombia as a Best Workplace For the fourth consecutive year, Computrabajo users selected the best companies to work for in Colombia. More than 1.6 million voters evaluated companies based on how they take care of their employees with salary and benefits, provide opportunities for training and growth, and protect workers with a strong safety culture. Halliburton achieved recognition as a top 10 company within all industries in the country, and as one of the top five companies in the oil and gas sector. Halliburton 2021 Annual & Sustainability Report Social 60 S3 Training and Development Critical elements of our Company’s growth and success include our skilled and knowledgeable employees who are committed to continual learning and development, the opportunity for our people to flourish in their careers and achieve their personal goals, and a strong pipeline of talent prepared to join the ranks of leadership and to carry our Company into the future. To learn more about our industry-recognized, best-in-class training via our employee development programs and processes, and about our talent identification and succession management policies and processes, please visit the Halliburton website. 2021 HIGHLIGHTS Expansion of Flexible Learning In 2021, Halliburton expanded modular learning opportunities to not only adapt to the ongoing COVID-19 pandemic, but also to take advantage of a valuable opportunity to make our training more accessible and efficient for our global workforce, and allow personnel to tailor learning opportunities to their specific needs. In doing so, we relied on different delivery methods for maximum flexibility, including virtual, self-paced, and hybrid formats. We now conduct 60% of our training outside of the traditional classroom, or in-person instructor, setting. To facilitate tailored learning closest to the point of application and more in the flow of work, we identify opportunities to shift training to a virtual or hybrid format. In addition to greater access and efficiency, virtual learning offers the benefit of more diverse attendees, with employees from various parts of the world participating in the same class, and therefore a more enriching learning experience. 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. Notable examples of our flexible training and development programs in 2021 include: • Our U.S. intern program, in which 86 interns worked with our business functions and PSLs, used a mix of in-person, virtual, and hybrid work opportunities. We hosted a full-day HalCamp to introduce interns to the Company, offering them the option of attending one of two on-site locations or joining a virtual orientation. To keep interns engaged and connected to Halliburton and with each other, we scheduled virtual and in- person lunch and learn sessions, along with virtual weekly water cooler chats and game nights. For our efforts, RippleMatch recognized Halliburton as one of 11 innovative companies in the U.S. • The Halliburton Business Development team launched the Advanced Negotiation Program in conjunction with the Texas A&M University Center for Executive Development. We offer this course in a virtual format. 61 Talent Identification and Succession Management Halliburton has more than 8,000 leaders among our employees. The ongoing identification and development of potential leadership talent ensures business continuity and strengthens our competitive advantage, both of which are critical for our short- and long-term success. In 2021, we identified more than 18,000 potential successors — our most diverse roster of successors to date. One of our most significant investments in developing future leaders in the Company is our executive education programs (BLD I, II, and III, and PLEP). Even in a year with travel restrictions impacting many countries, of our 324 program attendees, 40 different nationalities were represented and 25% were female. Expansion of Flexible Learning (continued) • After pausing for most of 2020 because of the pandemic, our executive education programming resumed in 2021. When required, we moved a portion of this programming, including Level III of the four-tiered Business Leadership Development (BLD) Program and the President’s Leadership Excellence Program (PLEP), to a virtual format. • Multiple PSLs have converted classroom training into modular, learner-driven formats with flexible delivery options to maximize the benefits of virtual instructor- led, self-paced, and on-the-job training for thousands of employees. This has reduced travel time, limited the impact of travel restrictions, and allowed motivated employees to own their development and accelerate their careers. Despite recent disruptions and continual changes, the quality of our training and education is unrivaled in our industry. For the ninth consecutive year, the Halliburton Global Competency Assurance Program maintained its status as the only full-spectrum oilfield services company to enjoy global accreditation by the International Association of Drilling Contractors (IADC) with no restrictions. Launch of the Data Science Academy In alignment with our Halliburton 4.0 digital approach, we introduced the Halliburton Data Science Academy in 2021. This new online, self-paced learning program enhances employees’ analytical skills and further expands our capabilities to address the large amounts of data to which we have daily access. During this year-long program, participants enhance their skills in functions such as data analytics, data engineering, data science, and machine learning. Upon completion of the program, participants understand how to use innovative solutions to effectively respond to complex business challenges. In March, PSL technology directors nominated more than 170 technology and Landmark employees for the pilot phase of the academy’s introduction, later expanding curricula access to an additional 160 employees.

As a result, we take deliberate steps to foster a culture of respect and inclusion, supported by our COBC and employment practices. For more extensive background information on our diversity initiatives, please visit the Halliburton website. 2021 HIGHLIGHTS Minority and Female Representation Increased diversity is an ongoing priority at Halliburton — and we made strides in advancing our Company’s diversity in 2021. In the U.S., the percentage of minorities in management positions improved 13% year over year. Female representation in leadership roles has improved 8% year over year. In addition, 19% of new hires in STEM roles were female. These types of roles feed into higher leadership positions within the Company, and we are pleased to report improving diversity. Listen and Respond As part of our commitment to inclusivity, Halliburton solicits feedback from employees on their workplace challenges, and empowers them to share their perspective and ideas to improve the overall employee experience — including performance, development, and work-life balance. In fact, employee feedback about mental health during the pandemic initiated our expansion of the EAP. One of our tools that we use to solicit feedback is the biannual Employee Pulse Survey (EPS). Our August 2021 EPS yielded our highest response rate yet at 77%. Through this survey, we confirmed that our employees are engaged, they know that their work matters, and they feel welcomed and included in our Our Diversity, Equity, and Inclusion Sustainability Commitment Provide a diverse, equitable, and inclusive environment that upholds our core values of collaboration and respect, and provides all employees opportunities for growth and development.

Regarding diversity and inclusion, 87% of our employees agreed that they can be their authentic selves at work, and they feel that the Company and their colleagues value their unique traits and ways of working. 63 Employee Resource Groups To further support a positive and inclusive work environment, Halliburton has employee resource groups (ERGs) for employees who share an interest in a particular topic or mission. These groups encourage engagement, collaboration, networking, and professional development while enhancing leadership skills and enabling career mobility within Halliburton. We engage with these ERGs to listen, empower, and help educate our workforce. Participation in our ERGs is voluntary and open to all employees. Halliburton has five ERGs: • Women Sharing Excellence (WSE) • Black Employees Leading in Inclusion, Excellence, Vision, and Education (BELIEVE) • Veterans Leadership Forum (VLF) • iMPACT • PRIDE First All-Female Halliburton Completion Tools (HCT) Crew Completes Operational Installation in Australia Halliburton achieved an important milestone: installing our VersaFlex® liner hanger system for a major oil and gas producer in Australia with an all- female crew. This is a first for any HCT operational installation in the area. The operation involved running liner to a depth of 13,232 ft through a 5,906-ft-long highly deviated section. The HCT completed the job without any HSE or SQ incidents. DE&I Training In 2021, the Company created and assigned a DE&I training course to the global workforce and required its completion by all full-time employees. This training introduces the acronym INCLUDE, with each letter in the acronym detailing an essential behavior supporting DE&I at Halliburton. The training features videos of Halliburton leaders from around the world describing what each of the behaviors mean to them. Inquire across differences Nurture collaboration Challenge yourself and others Lean into discomfort Understand differences Diversify your network Empathetic listening Building on a 2020 global townhall meeting focused on implicit bias and race, we assigned mandatory training on achieving racial equality in the workplace to all North American employees. We also made this training available globally. Topics covered in the training include practical strategies to address concerns about racial equality and the initiation of conversations about how we can recognize differences, seek understanding, and create a more inclusive environment. Development of Local Workforces As one of the world’s most diverse companies, we positively impact communities around the world by investing in the development of the local workforce. We make this investment to: • Be able to conduct business in native languages and with an understanding of local values and cultures, which facilitates better communication and improved day-to- day operations • Improve local economies • Make our workforce more representative of the local population • Enhance the quality of life for employees and their families through job creation, skill advancement, and career development We hire locals and give them access to our classroom and virtual training, on-the-job training, and competency programs. Additionally, we develop local relationships and align with universities and national oil companies to further skills and awareness of opportunities within our industry. Our focus is to increase the percentage of our workforce and our leadership that is localized, and we have made tremendous progress on our goals through these efforts. Currently, 92% of our workforce and 86% of our managers are locals of the areas where they work.

The team also provided a software grant that will enable students and lecturers to train on the DecisionSpace® suite of petrotechnical applications in drilling, geosciences, information management, and platform technology. This collaboration facilitates enhanced training for students of petroleum and geological engineering, chemistry, and earth and environmental sciences. Other aspects of the project include maintenance, training, and technical support for staff and student development. Our partnership with the university dates back to 2019 when we signed a memorandum of understanding (MOU) valued at $2 million. Under the MOU, we seek to transfer our knowledge, expertise, and technology to help develop local talent and, particularly, to invest in the future of the students who will one day be the leaders of the energy industry in Guyana and will shape the sustainability of the industry. In Guyana, Halliburton employs more than 50 nationals working as full-time employees and more than 10 Guyanese Co-Op participants. With our Company’s investment and partnership with the University of Guyana, these figures will continue to grow. All-Angolan Halliburton Team Successfully Completes Deepwater Openhole Logging Operation Recently, the Wireline and Perforating Angola team successfully completed a deepwater openhole logging operation for a major international oil company in Angola. This project marked the first time that a crew comprising all Angolan nationals — two field engineers and four operators — serviced the rig. It was also the first time that an entirely local Angolan crew completed an openhole logging operation in Angolan deep water. Halliburton 2021 Annual & Sustainability ReportSocial65 Investment in the Future Recruitment Through our Recruiting Inclusive Scholars in Energy (RISE) program, we support historically black colleges and universities (HBCU). As a result, we have deepened our diversity and inclusivity mission while building our pipeline of future talent. In Texas, Halliburton provided a $1 million scholarship fund to Prairie View A&M University. Over five years, this fund will support 72 scholarships for students of engineering, accounting, finance, and management information systems. We assign a Halliburton mentor to each scholarship recipient and offer professional development opportunities. We also invite scholarship recipients to join our internship program. Additionally, Halliburton is developing a relationship with Texas Southern University through charitable giving, career development support, and internships. Halliburton also supports initiatives to increase the representation of women in STEM roles. For Girl Day at The University of Texas at Austin, presented by the Women in Engineering Program (WEP), Halliburton provided financial support to give more than 8,000 female elementary and middle school students the opportunity to explore STEM roles through hands-on activities, videos, and demonstrations. Another event, the Halliburton Program for Women at Georgia Tech, serves to recruit and retain female engineering students in the academic program that produces the largest number of female engineering graduates in the U.S. Once the students arrive on campus, Halliburton assists them through mentorship and professional development opportunities. Halliburton has recruiting programs in place at academic institutions for internships and entry-level roles. To carry out our recruiting activities, we have developed relationships with diversity-focused student organizations, provide professional development sessions to students, engage our ERGs to participate in select university events, and participate in outreach efforts through programs supported by our Educational Advisory Board. Halliburton prioritizes diversity because it creates a more diverse pipeline for sourcing entry-level roles. We give our interns the opportunity to interact with our ERGs so they understand our focus on diversity and inclusion. In the last two years, our percentage of total female interns has increased from 39% to 43%. During that same time, we have increased the percentage of female interns in field operations from 48% to nearly 67%. In 2021, Halliburton remained well positioned in recruitment efforts despite the tight labor market. Our Global Talent Acquisition team engaged candidates in a variety of ways that included relationship building at universities, virtual career fairs, apprenticeship programs, employee referrals, and partnerships with local governments in their job candidate programs. We attracted candidates with clear career progression opportunities with a system that outlines the competencies and levels of proficiency required to advance within the Company. We also published job structures and salary bands for all positions globally, and published pay structures for the majority of countries where we operate, for transparency on job progression and associated compensation.

The team removed several bags full of waste. Specifically for Earth Day, Halliburton encouraged employees around the world to show us what they did for our environment to mark this occasion. We then created a video of their submissions. Halliburton 2021 Annual & Sustainability ReportSocial68 Health and Safety Making Highly Specialized Medical Care Accessible to Underprivileged Children Halliburton donated $33,845 to Deenanath Mangeshkar Hospital and Research Center in Pune, India, which provided underprivileged children with desperately needed medical care. These children suffer from life- threatening conditions such as cancer and heart disease, as well as other complex medical conditions such as epilepsy, neonatal issues, and ortho deformities. Often, these conditions require prolonged treatments, including highly specialized surgeries. In 2021, our financial contribution helped 40 children obtain medical treatment. Since the program’s inception in 2015, Halliburton has helped 238 children. Supporting Fire Safety in Oklahoma In Comanche, Oklahoma, where brush fires are common on the open plains, Halliburton donated a retired truck to the Comanche Fire Department (CFD). This truck, previously used to haul acid to customer locations for acidizing treatments, has a 2,000-gallon tank with a liner to protect against corrosion. Our donation will help the CFD overcome key challenges. These firefighters, who are responsible for extinguishing brush fires and protecting people and property, primarily serve on a volunteer basis, which means that they often work with limited budgets and lack vehicles capable of traversing rough terrain. With this truck’s large storage capacity and off-road capabilities, the CFD can carry higher volumes of water to remote locations to put out brush fires more efficiently. Social Services Delivering Meals to Food-Insecure People Renovating a Community Center Halliburton employees volunteered with the Houston Food Bank to help combat food insecurity in the community. Our volunteers inspected, sorted, and packaged food to create more than 12,000 meals. The Houston Food Bank is the largest food bank the U.S. in terms of size and distribution. It serves more than 1,800 community partners — including food pantries, soup kitchens, meal sites, and shelters — in 18 counties in Southeast Texas. Our Houston-area employees also participated in the 2021 Juice Box Challenge to support Kids’ Meals Inc.’s Summer Meal Program, which delivers meals to children living in food- insecure homes. Employees donated 13,784 juice boxes and volunteered to help with the Kids’ Meals food distribution. Our Company’s relationship with the Buckner Family Hope Center near our headquarters in Houston, Texas, dates back to 2009. Since then, we have donated more than $300,000 in support of this community center that offers after-school care, English as a Second Language (ESL) classes, parenting classes, a food pantry, a thrift store, and more. Recently, Halliburton made a financial donation to help cover renovation expenses for the facility — such as to pay for some cosmetic repairs and new furniture for children’s programming. Halliburton volunteers also painted the inside of two portable buildings, along with the kitchen and the children’s after-school room.

The TSS team, located across the UK, Denmark, Italy, and Albania, agreed to do a walkathon, or a sponsored walk, that each team member could complete in their respective locations and share with family and friends. Using the Halliburton Community Impact Portal, the TSS team shared the fundraising opportunity worldwide and garnered the support of Halliburton employees internationally. Ultimately, the team covered 740 miles and raised nearly $1,500 for Cash for Kids. Over the last year, the Halliburton Pipeline and Process Services (PPS) team in Aberdeen, Scotland, cultivated a close relationship with AberNecessities, a charity that focuses on families in Northeast Scotland who struggle with poverty — a problem only exacerbated by the pandemic and its resulting extended lockdowns in the UK. PPS team members began their volunteer work with AberNecessities in November 2020 by helping to create Christmas parcels for families that might otherwise not be able to afford gifts. However, during the pandemic it soon became clear that demand was growing for everyday necessities such as baby formula, diapers, and toiletries. The PPS team, on their own initiative, hosted a Christmas raffle and auctioned a signed Aberdeen football jersey donated by football legend Stewart McKimmie, the father of Halliburton employee Melissa McKimmie. These activities raised $2,287. Halliburton employees also assisted AberNecessities with the move into their new facility by volunteering as painters, gardeners, ride- on mower operators, van drivers, and other critical roles. The desire to transfer some of their energy into an important community cause and make a difference is how the team formed the “Beyond the Office Bubble” initiative. Now, the PPS team is generating more interest throughout Halliburton Europe to support this cause. The team has planned a black-tie anniversary fundraiser for AberNecessities in October 2022.

The tournament has raised more than $25 million for various charities across the U.S. since its inception in 1993. It is one of the largest non-PGA golf tournament fundraisers in the nation. This year, the tournament raised $2.6 million for more than 75 nonprofit organizations. We enjoyed 130 event sponsors and the participation of many of our suppliers, employees, and Halliburton volunteers. Total 2021 giving for Halliburton Foundation $2.3M Given to 75 nonprofit organizations supporting U.S. communities from the Halliburton Charity Golf Tournament $2.6M At Zanesville High School in Zanesville, Ohio, Halliburton launched the Challenge Program to improve students’ academic performance and to generate excitement about their potential in a future STEM career. In this program, students must meet certain academic marks. Halliburton selects winners in five categories: attendance, STEM, community service, academic improvement, and academic excellence. The winners receive a $500 scholarship to use at the school of their choice. Since the program’s introduction in 2016, Halliburton has contributed more than $20,000. Helping Protect Surrounding Communities from an Active Volcano in the Caribbean Halliburton supports the University of the West Indies (UWI) Seismic Research Centre, which is the agency responsible for monitoring earthquakes and volcanoes in the English-speaking islands of the Eastern Caribbean, including Trinidad and Tobago. For more than 60 years, the Centre has operated the largest earthquake- and volcano-monitoring initiative in the Caribbean, and promotes geologic hazard awareness, contingency planning for natural disasters, and development of early- warning systems. Prompted by the La Soufrière volcano’s sudden return to activity on the island of St. Vincent, Halliburton donated three borehole tiltmeters to the Centre to bolster ongoing monitoring of the volcano. Installed along the flanks of the volcano, the tiltmeters capture and deliver data in near real time to the Centre’s observatory. The tiltmeters will improve sensitivity to magma movement, and the information yielded will facilitate faster response times to deformation changes and also advance early- warning capabilities.

The software grants are evergreen with three-year renewable terms and include software maintenance and technical support. Halliburton awarded multimillion-dollar educational software grants to three public universities in Algeria (University of Science and Technology Houari Boumediene, University of Boumerdes, and University of Ouargla); Universiti Teknologi PETRONAS in Malaysia; and The Statler College of Engineering and Mineral Resources at West Virginia University. These grants support the education and development of students pursuing careers in the oil and gas industry. Through these grants, the UGP aims to facilitate teaching and research by enabling students and academics to interpret multi-disciplinary datasets using industry- leading software. Landmark hopes to strengthen the relationship between industry and academia, promote the uptake of Landmark’s software, and equip future generations with the skill sets required to solve real- world challenges. More than 150 academic institutions worldwide benefit from this program. The Halliburton Technology team hosted a series of virtual events with students at Imam Abdulrahman Bin Faisal University in Saudi Arabia. During these events, we shared our knowledge and experience with students to encourage them to pursue STEM careers, boost retention rates in technical disciplines, and develop business and leadership skills. Our Company’s experts also discussed various topics, including safety and security, soft skills, project management, and other subjects relevant to our business and the oil and gas industry. Corporate Giving Halliburton provides support to our local communities through cash donations and in-kind goods and services, which, in 2021, equaled approximately $2.5 billion. Giving Choices Each year, Halliburton employees around the world pledge money to their charities of choice through our annual workplace giving program, Giving Choices. With each employee’s pledge, Halliburton provides a 10% matching gift. During our 2021 Giving Choices campaign, employees donated more than $778,000 to nonprofit organizations around the world. Halliburton 2021 Annual & Sustainability ReportSocialHalliburton 2021 Annual & Sustainability Report Social 72 S6 Human Rights The incredible breadth of our operations and diversity of our workforce embodies our Company’s respect for the human rights and dignity of all people. Halliburton supports universal human rights, as defined by the United Nations Universal Declaration of Human Rights. To that end, we comply with all applicable employment laws, adhere to fair and ethical employment practices, and incorporate human rights into our policies on health, safety, and security. To read more about our beliefs and practices around human rights, including our Internal Human Rights Policy, please visit the Halliburton website. Our Human Rights Statement and COBC are also available on our website. 2021 HIGHLIGHTS Human Rights in the Supply Chain To better screen suppliers for potential human rights risks and abuses, Halliburton launched two internally developed tools to complement our new digital supplier management system. These tools include: • Our human rights dashboard, which evaluates suppliers’ risk at the product category, country, and spend level. This information can identify areas that require more detailed follow-up. • A more detailed human rights questionnaire that we tailor to individual suppliers and their risk levels. The questionnaire asks about topics such as forced labor, child labor, migrant and contract workers, bonded labor, prison labor, subcontractors, and labor brokers, as well as policies surrounding due diligence, training, working hours, recruitment fees, physical punishment, freedom of movement, and use of security personnel. For more information about our supply chain governance, please read Chapter G5 on Supply Chain in this report. Our Human Rights Sustainability Commitment Support universal human rights as defined by the United Nations Universal Declaration of Human Rights through fair and ethical employment practices and our Code of Business Conduct. New and Emerging Human Rights Regulations Halliburton complies with evolving regulations such as the UK Modern Slavery Act and the newly introduced Australia Modern Slavery Act, both of which require companies to disclose information on efforts to eradicate human trafficking and modern slavery from their business and global supply chains, including steps taken and controls put in place to address these human rights risks. Our statement of compliance with the UK Modern Slavery Act and our statement of compliance with the Australia Modern Slavery Act are available on our website. Halliburton monitors similar, emerging legislation around the world, such as that of the upcoming European Union and Norway requirements. As more countries debut human rights legislation, we will respond and confirm alignment with our policies and practices. 73 access to current information on community capacity. As a result, we added numerous indigenous contractors to Halliburton’s supply chain. Additionally, Halliburton employees engaged with indigenous communities in a variety of ways: • Leader-to-leader meetings • Celebration events for career training programs • Broad discussions with representatives from indigenous communities on how to foster long-term partnerships • Establishment of our Indigenous Community Investment Program, aligned with the Halliburton Pillars of Giving Lastly, we hired an indigenous and community relations manager with 25 years of experience to help us ensure we execute our indigenous inclusion strategy and form sustainable, mutually beneficial relationships. Throughout the year, Halliburton met with customers to inform them of our strategy and the progress we have made, and to discuss opportunities for collaboration. In 2022, we will expand our relationship-building efforts to more communities, while further enhancing our economic inclusion, cultural awareness training, and engagement with our customers. Indigenous Inclusion Strategy In 2021, building upon the 2020 development and initiation of our Indigenous Inclusion Strategy, Halliburton’s senior leadership team focused on improving indigenous inclusion and awareness throughout all facets of our Company and in our business relationships. This commitment led to the creation of our Indigenous Inclusion Leadership Steering Committee, which consists of a diverse group of individuals who are passionate about this initiative. This committee meets regularly to track progress and provide direction. First, we collaborated with experts to develop a cultural awareness program that reaches employees in the field, office, or at home through virtual training or full-day sessions. Second, we established a supply-chain-led Economic Inclusion Working Group to help us increase our number of indigenous suppliers and contractors. We assessed Halliburton’s contracting requirements and aligned them with indigenous community capacity. We then created and launched a repository of indigenous contractors in our operating areas, giving decision-makers on contracts Halliburton 2021 Annual & Sustainability ReportSocialHalliburton 2021 Annual & Sustainability Report Appendix 74 Appendix A1 Data Tables A2 Awards and Recognition A3 About the Report A1 Data Tables 75 Financial Data Financial Performance (Millions of U.S. Dollars (USD) and Shares, Except Per Share Data) Revenue Total Operating Expenses Operating Income (Loss) Income (Loss) Before Taxes Amounts Attributable to Company Shareholders:  Net Income (Loss) from Continuing Operations Basic and Diluted Income (Loss) Per Share from Continuing Operations Cash Dividends Per Share Basic and Diluted Common Shares Outstanding Net Working Capital Total Assets Total Debt Total Shareholders' Equity Cash Flows from Operating Activities  Capital Expenditures Depreciation, Depletion, and Amortization Total Capitalization Debt to Total Capitalization 2019¹ 2020¹ 2021 22,408 $ 14,445 $ 22,856 $ 16,881 $ (448) (1,122) $ $ (2,436) (3,220) $ $ (1,131) (1.29) $ $ 0.720 $ 875 (2,945) $ (3.34) $ 0.315 $ 881 6,334 $ 5,054 $ 15,295 13,495 1,800 1,252 1,457 1.63 0.180 892 5,637 25,377 $ 20,680 $ 22,321 10,327 $ 8,025 $ 2,445 $ 1,530 $ 1,625 $ 9,827 $ 4,983 $ 1,881 $ 728 $ 1,058 $ 9,138 6,728 1,911 799 904 18,352 $ 14,810 $ 15,866 56% 66% 58% $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ In 2021, the amount of net revenue generated by Halliburton in countries that have the 20 lowest rankings on Transparency International’s Corruption Perception Index comprises less than 1% of the Company’s total revenue.
