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. Adjusted operating income5 in the second quarter of

2026, excluding “Impairments and other credits,” was $683 million.

“I am pleased with Halliburton’s performance this quarter, and believe the global outlook for

Halliburton is strong. I expect our differentiated technology and value proposition set the

stage for revenue growth and margin expansion.” commented Jeff Miller, Chairman,

President and CEO.

“In international markets, I am excited about Halliburton’s contract awards and pipeline of

future opportunities. I see demand growth for our services and technology in every region

we serve.

“In North America, I am encouraged by the recovery we saw this quarter and I expect

incremental improvements through the year.

“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 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.

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 collaboration extends trusted data, domain

science, operational expertise, and applied AI to support predictive, asset-level

decision-making over the full production lifecycle.

•Halliburton successfully deployed its VersaFlex® expandable liner hanger system in

the bp-operated Azeri–Chirag–Gunashli project offshore Azerbaijan in the Caspian

Sea. The operation reinforces the companies’ long-standing collaboration and

demonstrates Halliburton’s ability to deliver high-value well construction solutions in

one of the region’s most complex offshore environments. The project highlights the

Company’s focus to support customer objectives throughout the well life cycle.

•Halliburton launched the Xaminer® Deep Testing logging service, the newest addition

to the Reservoir Xaminer™ formation testing service. Developed through close

collaboration with operators facing increasingly complex reservoirs, the service brings

deep-reading producibility and boundary identification earlier in the well life cycle to

support integrated decisions that complement traditional drill stem testing.

•Halliburton launched the Optimized Single-Trip Multi-Zone (OSTMZ®) sand control

system that reduces rig time, lowers total cost of ownership for operators, and safely

improves well productivity as complexity increases. 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

and improve operational efficiency, workflow predictability, and execution reliability.

This collaboration supports broader regional efforts toward integrated unconventional

development programs.

•Halliburton wins major integrated well construction contracts for the GranMorgu

deepwater development offshore Suriname, operated by TotalEnergies. The

agreement includes drilling and completions services for a long-term program.

Halliburton will deploy a fully integrated, digital and automation execution model that

unites planning, engineering, and operations to improve performance, accelerate

learning, and reduce total cost of ownership throughout well construction.

•Halliburton has been awarded a contract by Basra Oil Company to provide Integrated

Field Management Services and Engineering, Procurement, and Construction

Management (EPCM) for the development of the Bin Umar and Sindbad oil and gas

fields in southern Iraq. The contract scope includes field development planning,

production optimization, digital solutions, and EPCM services for the two fields.

Halliburton will deploy the Landmark portfolio to build a digital foundation that

connects subsurface insights, well delivery, production operations, and business

planning. Halliburton digitally integrates planning and execution to improve visibility,

increase efficiency, and support faster, higher-quality decisions.

(a)	During the six months ended June 30, 2026, Halliburton recognized a pre-tax credit of $95 million primarily due to a $54 million gain resulting from changes in our ownership interest in an equity investment, and a $10 million gain from remeasuring an equity investment to fair value. Other credits of $48 million were primarily due to a government refund recovery. These gains were partially offset by a $17 million loss on the sale of a portion of our chemical business, which closed in April 2026. During the six months ended June 30, 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.
(b)	Adjusted operating income is a non-GAAP financial measure which is calculated as: “Operating income” plus “Total impairments and other charges (credits)” for the respective periods. Management believes that operating income adjusted for impairments and other charges (credits) 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.

(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.
