Halliburton generates revenue by providing products and services to oil and gas companies across the entire lifecycle of a well—from exploration and drilling through completion, production, and intervention. The company operates through two primary business segments that collectively address every phase of hydrocarbon extraction. The Completion and Production segment is the larger of the two, generating $12.782 billion in fiscal year 2025, or approximately 57.6% of total revenue. This segment provides cementing services, stimulation services (including hydraulic fracturing), intervention services, artificial lift, and completion tools and services. Halliburton is the market leader in North American hydraulic fracturing and completions, a position that accounts for nearly half of the company's total revenue. The segment's cementing operations trace directly to the company's founding in 1919, when Erle Halliburton pioneered the use of cement to seal oil wells, prevent blowouts, and protect casing. Today, Halliburton's cementing services incorporate advanced chemistry, real-time monitoring, and digital optimization. The stimulation business includes hydraulic fracturing—performing the first commercial treatments in 1949 in Oklahoma and Texas—which remains the dominant method for unlocking unconventional oil and gas reservoirs in shale formations. The company's pressure pumping fleet, proppant logistics, and fracture design software represent a vertically integrated capability that few competitors can match. Completion tools include intelligent well systems, multistage fracturing systems, and sand control solutions that maximize reservoir contact and production rates. The Drilling and Evaluation segment generated $9.402 billion in fiscal year 2025, or approximately 42.4% of total revenue. This segment provides drilling services, drill bits, drilling fluids, wireline and perforating services, testing and subsea services, software and asset solutions, and project management. Halliburton's drilling services include directional drilling, managed pressure drilling, and integrated well construction solutions that allow operators to model, measure, and optimize well placement, stability, and reservoir evaluation. The company's drill bits business, enhanced by material science expertise, delivers polycrystalline diamond compact (PDC) and roller cone bits optimized for specific formations. Drilling and completions fluids leverage Halliburton's century of material science expertise to manage wellbore stability, pressure control, and formation damage. Wireline services provide logging, perforating, and well intervention using electric cable conveyance. The software and asset solutions business offers digital platforms for reservoir characterization, drilling optimization, and production analytics. Revenue recognition follows standard patterns for the oilfield services industry: services revenue is recognized as work is performed, typically on a day-rate or unit-of-work basis; product sales revenue is recognized upon delivery; and long-term project revenue is recognized over time using input methods. The company's customer base includes virtually every major oil and gas producer globally, from supermajors like ExxonMobil and Shell to national oil companies like Saudi Aramco and Petrobras to independent shale producers in the Permian Basin. Customer concentration is managed through a diversified portfolio across geographies and customer types. Geographic revenue distribution in 2025 reflected the company's global footprint: North America accounted for 39% of revenue (~$8.65 billion), driven primarily by US land drilling and completions activity; the Middle East/Asia region contributed $5.832 billion (~26.3%), with strong activity in Saudi Arabia, UAE, and Iraq; Latin America generated $3.935 billion (~17.7%), with significant operations in Mexico, Brazil, Argentina, and Colombia; and Europe/Africa/CIS contributed $3.351 billion (~15.1%), including North Sea, West Africa, and Russian operations. The company's integrated project management services combine multiple product lines under turnkey contracts, providing customers with single-point accountability for complex drilling and completion projects. Halliburton's capital allocation framework prioritizes returns to shareholders, with a goal of returning at least 50% of annual free cash flow through dividends and share repurchases. The company paid quarterly dividends of $0.17 per share in 2024 and 2025, for an annual dividend of $0.68 per share and a yield of approximately 1.68%. Share repurchases totaled $500 million in the first half of 2024 alone, though the program was paused during the August 2024 cybersecurity incident. Capital expenditures were $677 million in the first half of 2024, focused on maintenance and technology upgrades rather than fleet expansion. The company's balance sheet carries $7.64 billion in long-term debt and $2 billion in cash, with a debt-to-equity ratio of 74.65%. Halliburton's gross margin is supported by its technology differentiation and operational scale, though margin pressure from customer pricing negotiations and inflation in chemicals, cement, and logistics costs remains a persistent challenge. The company attempts to pass cost increases to customers and has implemented cost reduction initiatives targeting approximately $100 million in quarterly savings.
