HOUSTON – July 21, 2026 – Halliburton Company (NYSE: HAL) announced today net income of $534 million, or $0.64 per diluted share, for the second quarter of 2026 and adjusted net income4, excluding “Impairments and other credits”, of $461 million, or $0.55 per diluted share. This compares to net income for the first quarter of 2026 of $461 million, or $0.55 per diluted share. Halliburton’s total revenue for the second quarter of 2026 was $5.7 billion , compared to total revenue of $5.4 billion in the first quarter of 2026 . Operating income was $778 million in the second quarter of 2026, compared to operating income of $679 million in the first quarter of 2026.

Operating Segments Completion and Production

Halliburton/Page 2 Completion and Production revenue in the second quarter of 2026 was $3.2 billion, an increase of $186 million, or 6% sequentially, while operating income was $474 million, an increase of $35 million, or 8% sequentially. These results were primarily driven by increased stimulation activity in the Western Hemisphere and improved well intervention services in Asia. Partially offsetting these increases were lower specialty chemicals activity in North America resulting from the completed sale of a portion of our chemical business, decreased cementing activity in Latin America, and lower activity across multiple product service lines in the Middle East. Drilling and Evaluation Drilling and Evaluation revenue in the second quarter of 2026 was $2.5 billion, an increase of $126 million, or 5% sequentially, while operating income was $338 million, a decrease of $13 million, or 4% sequentially. Revenue improvements were primarily driven by increased drilling-related services and higher wireline activity in North America and Europe/Africa, and increased drilling-related services in Asia. Partially offsetting these increases were lower software sales globally, decreased project management activity in Latin America and lower wireline activity in the Middle East. Operating income decreased due to the seasonal roll off of software sales. Geographic Regions North America North America revenue in the second quarter of 2026 was $2.3 billion, an increase of 7% sequentially. This increase was primarily driven by higher stimulation activity and increased well construction activity in US Land, and higher fluids activity in the Gulf of America. Partially offsetting these increases were lower specialty chemicals activity in US Land following the sale of a portion of our chemical business and decreased drilling activity in the Gulf of America. International International revenue in the second quarter of 2026 was $3.4 billion, an increase of 5% when compared to the first quarter of 2026. Latin America revenue in the second quarter of 2026 was $1.1 billion, an increase of 3% sequentially. These results were primarily driven by increased stimulation activity in Argentina and Mexico, and improved completion tool sales in Mexico. Partially offsetting these increases were lower activity across multiple product service lines in the Caribbean, decreased well construction activity in Mexico and Ecuador, and decreased completion tool sales in Brazil.

Halliburton/Page 3 Europe/Africa revenue in the second quarter of 2026 was $1.0 billion, an increase of 19% sequentially. These results were primarily driven by improved activity across multiple product service lines in the North Sea, increased well construction activity in Namibia and Egypt, higher completion tool sales in the Mediterranean and Ivory Coast, and increased project management activity in Angola. Partially offsetting these increases were decreased software sales across the region and lower activity across multiple product service lines in Libya. Middle East/Asia revenue in the second quarter of 2026 was $1.3 billion, a decrease of 2% sequentially. These results were primarily driven by lower activity across multiple product service lines in Kuwait, Iraq, and Qatar as a result of the ongoing geopolitical conflict in the Middle East. Partially offsetting these decreases were higher well construction activity in Saudi Arabia and the United Arab Emirates, and increased drilling-related services and higher well intervention services in Asia. Other Financial Items During the second quarter of 2026, Halliburton: • Repurchased approximately $200 million of its common stock. • Paid dividends of $0.17 per share. • Spent $46 million on SAP S4 migration. • Recognized a pre-tax credit of $95 million, related to “Impairments and other credits.” Selective Technology & Highlights • Halliburton and Shape Digital entered a strategic collaboration to advance digital asset performance management through a unified asset view that connects subsurface and surface intelligence.

The system supports efficient completion operations and increases reservoir coverage in complex multizone wells. Operators that complete multizone wells often manage extended schedules, multiple service-tool trips, and increased operational exposure. The OSTMZ sand control system addresses these challenges and treats multiple zones in a single trip, without deployment-tool repositioning or repeated surface-equipment testing. • Halliburton held its 2026 Technology Showcase from May 4-7 in Houston, which was attended by nearly 400 industry professionals from around the world. The event brought industry and technical leaders together and showed how digital capabilities translate into real-time execution at the wellsite to improve asset performance for our customers. Halliburton showcased measurable value from the integration of software, artificial intelligence, and automation into real-time operations. • Halliburton announced the acquisition of InformatiQ AS, a Norway‑based software company that develops cloud‑native applications for subsurface, drilling, well, and logistics data. The acquisition converts a long‑standing collaboration into full ownership, strengthens Landmark’s Agile Asset Management offering, and extends its digital portfolio into new operational domains. • Halliburton was awarded lump sum turnkey contracts by Aramco for multiple onshore fields in the Kingdom of Saudi Arabia. The awards expand Halliburton’s role in the program and demonstrate the Company’s ability to grow through integrated well delivery at scale. The multi-year contracts encompass approximately 285 planned wells. Halliburton will deliver a fully integrated execution model that includes oil re- entry operations, drilling, completions, and workovers. The integrated approach supports maximum asset value through operational consistency and timely well delivery and helps advance Aramco’s objectives to maintain efficiency in its onshore portfolio. • Halliburton was awarded a multi-year contract from Aramco to deliver integrated stimulation and completion services for unconventional gas development in the Kingdom of Saudi Arabia. This award is part of a broader multi-billion contract, supporting one of the largest unconventional gas development programs globally. This award builds on Halliburton’s established portfolio supporting Aramco’s unconventional program. Across many of the Kingdom’s unconventional plays, Halliburton delivers a comprehensive suite of drilling and completion solutions. Its integrated service model is designed to support high-intensity development programs
