Exhibit 99.1

HALLIBURTON ANNOUNCES FIRST QUARTER 2026 RESULTS

•Net income of $0.55 per diluted share.

•Revenue of $5.4 billion and operating margin of 13%.

•Cash flow from operations of $273 million and free cash flow1 of $123 million.

•Approximately $100 million of share repurchases.

HOUSTON – April 21, 2026 – Halliburton Company (NYSE: HAL) announced today net

income of $461 million, or $0.55 per diluted share, for the first quarter of 2026. This

compares to net income for the first quarter of 2025 of $204 million, or $0.24 per diluted

share, and adjusted net income2, excluding impairments and other charges, of $517 million,

or $0.60 per diluted share, in the first quarter of 2025. Halliburton’s total revenue for the first

quarter of 2026 was $5.4 billion, flat when compared to the first quarter of 2025. Operating

income was $679 million in the first quarter of 2026, compared to operating income of $431

million in the first quarter of 2025, and adjusted operating income3, excluding impairments

and other charges, of $787 million in the first quarter of 2025.

“I am pleased with Halliburton’s performance this quarter,” commented Jeff Miller, Chairman,

President and CEO.

“In North America, I see clear signs that we are in the early innings of a recovery.

“In international markets, our performance around the world outpaced disruptions from the

Middle East conflict.

“I expect that our consistent focus on returns and capital discipline will drive long-term

success for Halliburton and its shareholders,” concluded Miller.

Operating Segments

Completion and Production

Completion and Production revenue in the first quarter of 2026 was $3.0 billion, a decrease

of $104 million, or 3%, when compared to the first quarter of 2025, while operating income

was $439 million, a decrease of $92 million, or 17%, when compared to first quarter of 2025.

These results were primarily driven by lower stimulation activity in North America, and lower

completion tool sales and decreased pressure pumping services in the Middle East. Partially

offsetting these decreases were higher completion tool sales in the Western Hemisphere,

and improved pressure pumping services in Africa.

Drilling and Evaluation

Drilling and Evaluation revenue in the first quarter of 2026 was $2.4 billion, an increase of

$89 million, or 4%, when compared to the first quarter of 2025, while operating income was

$351 million, flat when compared to the first quarter of 2025. These results were primarily

driven by higher project management activity in Latin America and increased drilling-related

services in Europe and the Western Hemisphere. Partially offsetting these increases were

lower activity across multiple product service lines in the Middle East, lower wireline activity

in the Eastern Hemisphere, and decreased fluid services in the Gulf of America.

In the first quarter of 2026, the geopolitical conflict in the Middle East affected both divisions,

with an impact of approximately 2 to 3 cents of net income per diluted share.

Geographic Regions

North America

North America revenue in the first quarter of 2026 was $2.1 billion, a 4% decrease when

compared to the first quarter of 2025. This decline was primarily driven by lower stimulation

activity and decreased artificial lift activity in US Land, and lower stimulation activity and

decreased fluid services in the Gulf of America. Partially offsetting these decreases were

increased drilling-related services in US Land and higher completion tool sales in the region.

International

International revenue in the first quarter of 2026 was $3.3 billion, an increase of 3% when

compared to the first quarter of 2025.

Latin America revenue in the first quarter of 2026 was $1.1 billion, an increase of 22% year

over year. This increase was primarily driven by higher activity across multiple product

service lines in Ecuador, the Caribbean, and Brazil, and improved stimulation activity in

Mexico and Argentina. Partially offsetting these increases were lower project management

activity and decreased drilling-related services in Mexico.

Europe/Africa revenue in the first quarter of 2026 was $858 million, an increase of 11% year

over year. This increase was primarily driven by increased drilling-related services and

higher completion tool sales in Norway, and improved pressure pumping services in Angola.

Partially offsetting these increases were lower completion tool sales in the Caspian Area and

decreased drilling-related services in Namibia.

Middle East/Asia revenue in the first quarter of 2026 was $1.3 billion, a decrease of 13%

year over year. This decrease was primarily driven by lower activity across multiple product

service lines in Saudi Arabia and decreased drilling-related services in Qatar. Partially

offsetting these decreases were higher completion tool sales and improved fluid services in

Asia.

Other Financial Items

During the first quarter of 2026, Halliburton:

•Repurchased approximately $100 million of its common stock.

•Paid dividends of $0.17 per share.

•Spent $42 million on SAP S4 migration.

Selective Technology & Highlights

•Halliburton launched the HyperSteer™ MX directional drill bit, an industry-first

shankless matrix-body bit that improves durability and maximizes directional control.

The bit delivers longer runs and fewer trips, resists erosion and abrasion, and

performs reliably in high-flow, abrasive environments. HyperSteer™ MX directional

drill bits utilize advanced matrix materials to resist erosion and abrasion, extend bit

life in abrasive, high-flow environments, and improve efficiency and reliability during

operations.

•Halliburton and the Agency for Science, Technology and Research (A*STAR),

Singapore's lead public sector research and development agency, announced the

launch of the Next-Generation Energy Xccelerator Joint Lab. This initiative aims to

accelerate the development and commercialization of advanced well completion

technologies for the energy industry. The project is also supported by the Singapore

Economic Development Board.

•Halliburton launched the XTR™ CS injection system, a wireline-retrievable safety

valve solution engineered for CO₂ injection in carbon capture, utilization, and storage

wells. The system provides flexibility as a primary or contingency safety valve or as a

deep-set reservoir fluid-flowback prevention device. Unlike traditional surface-

controlled wireline valves, the XTR injection system’s non-elastomeric design helps

minimize leak paths and eliminate reliance on hydraulic operation systems. This

system remains at steady performance at any setting depth, to simplify operations

and inventory management.

•Halliburton launched the RangeStar™ Geothermal Well Spacing and Intercept

Service, a part of the family of RangeStar™ magnetic ranging services, a next-

generation solution that supports geothermal development through faster, more

accurate, and fully integrated well placement. Designed for complex geothermal

environments, the RangeStar Geothermal Well Spacing and Intercept Service

delivers reliable performance that reduces uncertainty and simplifies operations.

Rapid ranging determination reduces decision time from hours to minutes, supports

detection distances up to 130 meters, and improves accuracy within formations and

depths.

•Halliburton, in collaboration with ExxonMobil Guyana, Sekal, and Noble, delivered a

groundbreaking step forward in digital well construction to achieve the deepwater

industry’s first fully automated geological well placement with complete rig automation

in offshore Guyana. The project combined rig automation, automated subsurface

interpretation and well placement, and real-time hydraulics to establish a new

benchmark for well construction performance, reservoir contact, and execution

efficiency.

During the three months ended March 31, 2025, Halliburton recognized a pre-tax charge of $356 million as a result of

severance costs, an impairment of assets held for sale, an impairment on real estate facilities, and other items, primarily

related to legacy environmental remediation cost estimate increases. During the three months ended December 31, 2025,

Halliburton recognized a pre-tax charge of $83 million as a result of an equity in earnings loss, an impairment of assets held

for sale, severance costs, and other items.

(b)

Adjusted operating income is a non-GAAP financial measure which is calculated as: “Operating income” plus “Total

impairments and other charges” for the respective periods. Management believes that operating income adjusted for

impairments and other charges is useful to investors to assess and understand operating performance, especially when

comparing those results with previous and subsequent periods or forecasting performance for future periods, primarily

because management views the excluded items to be outside of the company's normal operating results. Management

analyzes operating income without the impact of these items as an indicator of performance, to identify underlying trends in

the business, and to establish operational goals. The adjustments remove the effect of these items.

(c)

We calculate operating margin by dividing operating income by revenue. We calculate adjusted operating margin, a non-

GAAP financial measure, by dividing adjusted operating income by revenue. Management believes adjusted operating

margin is useful to investors to assess and understand operating performance.

(c)

Adjusted net income attributable to company is a non-GAAP financial measure which is calculated as: “Net income

attributable to company” plus “Total adjustments, net of taxes” for the respective periods. Management believes net

income adjusted for impairments and other charges, along with the tax adjustments is useful to investors to assess and

understand operating performance, especially when comparing those results with previous and subsequent periods or

forecasting performance for future periods, primarily because management views the excluded items to be outside of the

company's normal operating results. Management analyzes net income without the impact of these items as an indicator

as: “Adjusted net income attributable to company” divided by “Diluted weighted average common shares outstanding.”

Management believes adjusted net income per diluted share is useful to investors to assess and understand operating

(a)

Free Cash Flow is a non-GAAP financial measure which is calculated as “Total cash flows provided by operating activities”

less “Capital expenditures” plus “Proceeds from sales of property, plant, and equipment.” Management believes that Free

Cash Flow is a key measure to assess liquidity of the business and is consistent with the disclosures of Halliburton's

direct, large-cap competitors.
