Independent Accountants’ Review Report
To the Board of Directors and Management
Halliburton Company:
Report on the Accompanying Statements on Sustainability Metrics
Conclusion
We have reviewed whether Halliburton Company’s (the Company) Statement of Greenhouse Gas (GHG)
Emissions, Statement of Energy Consumption, Statement of Workplace Health and Safety, and Statement ofFemale Diversity and Localized Workforce and the related notes (collectively, the Statements on SustainabilityMetrics, or the Statements) as of and for the year ended December 31, 2023 have been prepared inaccordance with the reporting criteria set forth in Note 2 (the Criteria).
Based on our review, we are not aware of any material modifications that should be made to the Statements onSustainability Metrics as of and for the year ended December 31, 2023 in order for them to be prepared inaccordance with the Criteria.
Basis for Conclusion
Our review was conducted in accordance with attestation standards established by the American Institute ofCertified Public Accountants in AT-C Section 105, Concepts Common to All Attestation Engagements, andAT-C Section 210, Review Engagements. We are required to be independent and to meet our other ethicalrequirements in accordance with relevant ethical requirements related to the engagement. We believe that theevidence we have obtained is sufficient and appropriate to provide a reasonable basis for our conclusion.
Responsibilities for the Statements on Sustainability Metrics
Management of the Company is responsible for:•designing, implementing and maintaining internal control relevant to the preparation of the Statements thatare free from material misstatement, whether due to fraud or error;•

selecting or developing suitable criteria for preparing the Statements and appropriately referring to or
describing the criteria used; and•preparing the Statements in accordance with the Criteria.

Inherent Limitations in Preparing the Statements on Sustainability Metrics
As described in Note 2 of the Statements, the Company obtains actual energy consumption and emissions
activity data from across its global operations to the extent available. However, there are estimation
uncertainties resulting from the inherent limitations in the methodologies used to calculate energy consumption
and emissions activity for the subset of facilities and activities where actual use data is not available.
Additionally, there are estimation uncertainties resulting from inherent limitations in the methodologies used to
calculate workforce health and safety metrics due to identification of new facts and circumstances during
investigations of reported incidents and the calculation of health, safety, and environment hours.

KPMG LLP, a Delaware limited liability partnership and a member firm of
the KPMG global organization of independent member firms affiliated withKPMG International Limited, a private English company limited by guarantee.

Our Responsibilities
The attestation standards established by the American Institute of Certified Public Accountants require us to:•plan and perform the review to obtain limited assurance about whether any material modifications should
be made to the Statements in order for them to be prepared in accordance with the criteria; and•express a conclusion on the Statements based on our review.

Summary of the Work we Performed as the Basis for Our Conclusion
We exercised professional judgment and maintained professional skepticism throughout the engagement. We
designed and performed our procedures to obtain evidence that is sufficient and appropriate to provide a basisfor our conclusion. Our procedures selected depended on our understanding of the Statements and otherengagement circumstances, and our consideration of areas where material misstatements are likely to arise. In
carrying out our engagement, we:•inquired of management to obtain an understanding of the methodology and inputs used in preparing theStatements and deriving the included metrics;•

performed analytical procedures;•

recalculated a selection of the metrics based on the Criteria and considered the appropriateness ofemissions factors used;•inspected a haphazard selection of supporting documentation and evaluated inputs to:–engine-specific emissions factors derived from manufacturer-provided data;–

supplier-specific emissions factors; and–estimates related to the consumption and emissions metrics;•

inspected a haphazard selection of supporting documentation related to health and safety metrics; and•read the Statements and compared the disclosures to the underlying methodologies, inputs, estimates andassumptions reviewed.

The procedures performed in a review vary in nature and timing from, and are substantially less in extent than,an examination, the objective of which is to obtain reasonable assurance about whether the subject matter
information is prepared in accordance with the criteria, in all material respects, in order to express an opinion.
Because of the limited nature of the engagement, the level of assurance obtained in a review is substantiallylower than the assurance that would have been obtained had an examination been performed.

Standard are referred to as the “GHG Protocol” in this document.
Estimation Uncertainties
The Company obtains actual energy consumption and emission activity data from across our global operations to the extent available.
However, there are estimation uncertainties resulting from the inherent limitations in the methodologies used to calculate energy
consumption and emissions activity for the subset of facilities and activities where actual use data is not available. The methodologies aredescribed within this document for energy consumption and Scope 1 and 2 emissions. Additionally, there are estimation uncertainties
resulting from inherent limitations in the methodologies used to calculate workforce health and safety metrics due to identification ofnew facts and circumstances during investigations of reported incidents and the calculation of health, safety, and environment hours. The
methodologies are described within this document for workplace health and safety metrics.
NOTE 3: GHG AND ENERGY REPORTING
Organizational Boundaries
The Company has selected the operational control approach to account for and report the consolidated GHG emissions and energy
consumption. Under the operational control approach, the Company accounts for 100% of the GHG emissions and energy consumption
from operations over which it has control and excludes GHG emissions and energy consumption from operations in which it owns aninterest but has no control. The Company reports 100% of operations in which the Company or one of its subsidiaries exercises
operational control.
Operational Boundaries
The Company identifies energy consumption and categorizes the emissions associated with the Company’s operations between Scope 1and Scope 2 emissions. Fuel consumption and Scope 1 emissions occur from sources that are owned or controlled by the Company. Our
fuel consumption and Scope 1 emissions primarily relate to the combustion of fuel utilized for our fracturing equipment, offshore
equipment, vehicles, and facilities. Our electricity consumption and Scope 2 emissions primarily relate to the purchase of electricity
consumed across our global facility portfolio, as well as electricity consumed by our electric fracturing units. Purchased electricity isdefined as electricity that is purchased or otherwise brought into the organizational boundary of the Company. The Company also
includes electricity consumption and Scope 2 emissions related to our controlled operating equipment that uses electricity generated bythird-party generators on offshore rigs.
Greenhouse Gases Covered
GHG emissions are presented in metric tons of carbon dioxide equivalent (CO2e) and include three of the seven greenhouse gases coveredby the Kyoto Protocol: carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Hydrofluorocarbons (HFCs), perfluorocarbons(PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3) are not relevant to the core operations of the Company.
Methodology and Emissions Factors
The Company applies emissions factors to energy consumption data to derive CO2e values. Energy consumption data is based on actual
operating usage, manufacturer-provided data, and/or utility usages from purchases. When actual data is not available, energy
consumption estimations are based on fuel purchase records, miles driven, operating hours, facility utilized actual square footage and U.S.
Energy Information Administration (EIA) Annual Electricity Consumption Rate from the 2021 Commercial Buildings Energy
Consumption Survey (CBECS) data, historical facility consumption data, and/or average hourly consumption for field equipment. Scope 2emissions are calculated under both location-based and market-based methods. Market-based emissions include electricity procurement
decisions including contracts and renewable energy certificates (RECs). The Company does not use residual mix factors in the calculationof market-based emissions. Additionally, the Company does not include emissions from refrigerants or fugitive emissions and does not
combust biogenic emissions sources. There are no emissions applicable to biologically sequestered carbon (e.g., CO2 from burning
biomass or biofuels).
GHG emissions are calculated using the Global Warming Potentials (GWP) from the Intergovernmental Panel on Climate Change (IPCC)
Sixth Assessment Report (AR6). Scope 1 emissions are calculated using engine-specific emissions factors derived from manufacturerprovided data or U.S. Environmental Protection Agency (EPA) emission factors (EPA Emissions Factors for Greenhouse Gas Inventories,
September 2023). Scope 2 emissions are calculated using supplier-specific emissions factors for electric engines that do not obtain powerfrom the grid, U.S. EPA (EPA eGRID 2021 Table 6, February 2023), or International Energy Agency (IEA) grid factors (IEA 2023 using2021 factors).

NOTE 5: WORKPLACE HEALTH AND SAFETY
As part of our ongoing operations, employees and contractors perform activities that carry inherent safety and service quality risks. TheCompany reports the following incident rates using the criteria listed below for all worldwide employees and contractors during theperiod. Employees include full-time or part-time individuals working at the time of an incident. Contractors include individuals who areperforming services under a contractual agreement and for a specific, limited period of time.
Total Recordable Incident Rate
The Company reports the Total Recordable Incident Rate (TRIR) based on SASB Oil and Gas Services Standard EM-SV-320a.1.1 and SASBEM-SV-320a.1.6, which requires reporting recordable incidents for work-related injuries and illnesses per 200,000 hours worked by all
employees and contractors during the year. According to U.S. Occupational Safety and Health Administration (OSHA) standard U.S. 29 CFR
1904.7 General Recording Criteria, an injury or illness is considered a recordable incident if it results in any of the following: death, days
away from work, restricted work or transfer to another job, medical treatment beyond first aid, or loss of consciousness. Additionally, asignificant injury or illness diagnosed by a physician or other licensed health care professional is considered a recordable incident, even if
it does not result in death, days away from work, restricted work or job transfer, medical treatment beyond first aid, or loss ofconsciousness.
Fatalities, Lost Time Incident Rate, and Preventable Recordable Vehicle Incident Rate
Fatalities, Lost Time Incident Rate (LTIR) and Preventable Recordable Vehicle Incident Rate (PRVIR) are reported in accordance withmanagement-determined criteria. OSHA standard U.S. 29 CFR 1904.7 General Recording Criteria is used to determine qualifying fatalities
and lost time incidents. Lost time incidents are defined as any work-related injuries or illnesses resulting in days away from work. TheCompany reports LTIR as the number of lost time incidents per 200,000 hours worked by employees and contractors during the year. TheCompany reports PRVIR as the number of preventable recordable vehicle incidents per one million miles driven by employees andcontractors for business use. Recordable vehicle incidents include accidents defined by guidance from the Federal Motor Carrier Safety
Administration (FMCSA) Regulation 49 CFR 390.5 that are recordable based on OSHA standard U.S. 29 CFR 1904.7 General Recording
Criteria. Recordable vehicle incidents are determined to be preventable if they do not meet one or more of the non-preventable reporting
criteria, which were established by the Company based on the FMCSA Crash Preventability Determination Program.
NOTE 6: FEMALE DIVERSITY AND LOCALIZED WORKFORCE
Female Diversity
Female diversity metrics are reported based upon GRI Standard 405-1(b)(i). The Company reports information related to female
diversity in the total workforce, which includes all full-time active employees, and in all management positions. Information related togender is reported during the hiring process. Management positions include employees with job levels of supervisor/coordinator andabove.
Percentage of Localized Workforce by Region
Localized workforce metrics are reported in accordance with management-determined criteria. The Company discloses the percentage oflocalized workforce by region. Localized workforce (locals) is defined as full-time active employees who are not classified as expatriates
or commuters. Expatriates and commuters are defined as employees on international assignments away from their home country. These
data metrics are calculated by dividing the number of locals in the region by the total number of full-time employees in the region.
