HOUSTON – October 21, 2025 – Halliburton Company (NYSE: HAL) announced today net

income of $18 million, or $0.02 per diluted share, for the third quarter of 2025 and adjusted

net income4, excluding “Impairments and other charges” and other items, of $496 million, or

$0.58 per diluted share. This compares to net income for the second quarter of 2025 of $472

million, or $0.55 per diluted share. Halliburton’s total revenue for the third quarter of 2025

was $5.6 billion, compared to total revenue of $5.5 billion in the second quarter of 2025.

Operating income was $356 million in the third quarter of 2025, compared to operating

income of $727 million in the second quarter of 2025. Adjusted operating income5 in the third

quarter of 2025, excluding “Impairments and other charges”, was $748 million.

“I am pleased with Halliburton’s third quarter performance. We delivered total company

revenue of $5.6 billion dollars and adjusted operating margin of 13%. We also took steps

that will deliver estimated savings of $100 million dollars per quarter, reset our 2026 capital

budget and idled equipment that no longer meets our return expectations,” commented Jeff

Miller, Chairman, President and CEO.

"In the international market, our value proposition is winning with customers, we are

demonstrating differentiated performance both on and off-shore, and our growth engines are

on track.

“In North America, we are executing our strategy to Maximize Value — this means we are

prioritizing returns, technology leadership, and working with leading operators. I am

confident that our strategy execution will drive further outperformance.

“We are committed to returning cash to shareholders, maintaining cost and capital discipline,

and investing in differentiated technologies that drive long-term performance,” concluded

Miller.

Operating Segments

Completion and Production

Completion and Production revenue in the third quarter of 2025 was $3.2 billion, an increase

of $52 million, or 2%, when compared to the second quarter of 2025, while operating income

in the third quarter of 2025 was $514 million, flat when compared to the second quarter of

2025. Higher completion tool sales and increased artificial lift activity in North America,

improved cementing activity in Africa and Latin America were partially offset by lower

completion tool sales internationally, decreased well intervention services in Middle East/

Asia, and lower cementing activity in North America. Operating income was further

adversely impacted by rig reductions in Saudi Arabia.

Drilling and Evaluation

Drilling and Evaluation revenue in the third quarter of 2025 was $2.4 billion, an increase of

$38 million, or 2%, when compared to the second quarter of 2025, while operating income in

the third quarter of 2025 was $348 million, an increase of $36 million, or 12%, when

compared to the second quarter of 2025. These results were primarily driven by higher

project management and improved wireline activity in Latin America, increased drilling

services in North America and Europe/Africa, and higher software sales in Europe/Africa.

Partially offsetting these increases were lower activity across multiple product service lines

in the Middle East and decreased fluid services in North America and Europe/Africa.

Geographic Regions

North America

North America revenue in the third quarter of 2025 was $2.4 billion, an increase of 5% when

compared to the second quarter of 2025. These results were primarily driven by increased

stimulation activity in US Land and Canada, and higher completion tool sales and increased

wireline activity in the Gulf of America. Partially offsetting these increases were lower

cementing activity in US Land and decreased stimulation activity in the Gulf of America.

International

International revenue in the third quarter of 2025 was $3.2 billion, flat when compared to the

second quarter of 2025.

Latin America revenue in the third quarter of 2025 was $996 million, an increase of 2%

sequentially. This increase was primarily driven by higher project management activity

across the region and increased drilling services in Argentina. Partially offsetting these

increases were decreased activity across multiple product service lines in Mexico and lower

completion tool sales in Brazil.

Europe/Africa/CIS revenue in the third quarter of 2025 was $828 million, flat sequentially.

These results were primarily driven by improved completion tool sales in Norway, and

increased drilling-related services in Namibia. Offsetting these increases were lower

completion tool sales in the Caspian Area and lower fluid services across Europe.

Middle East/Asia revenue in the third quarter of 2025 was $1.4 billion, a decrease of 3%

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

service lines in Saudi Arabia. Partially offsetting this decrease were improved pressure

pumping services in Qatar, increased artificial lift activity in Kuwait, and higher completion

tool sales and improved fluids services in Asia.

Other Financial Items

During the third quarter of 2025, Halliburton:

•Repurchased approximately $250 million of its common stock.

•Paid dividends of $0.17 per share.

•Spent $50 million on SAP S4 migration.

•Incurred a total charge of $540 million related to “Impairments and other charges”

and other items.

During the nine months ended September 30, 2024, Halliburton recognized a pre-tax charge of $116 million as a result of severance costs, an impairment of assets held for sale, expenses related to a cybersecurity incident, a gain on a fair value adjustment of an equity investment, 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.

During the nine months ended September 30, 2024, Halliburton incurred a charge of $82 million in March 2024, primarily due to the impairment of an investment in Argentina and currency devaluation in Egypt.
(c)	The adjustments in the table above include a $125 million tax expense associated with a valuation allowance recorded against our deferred tax assets, which resulted from the impact on the realizability of our United States foreign tax credits due to the OBBBA, as well as the tax effect on impairments and other charges and the impairment of an investment in Argentina, recorded during the nine months ended September 30, 2025. During the nine months ended September 30, 2024, the adjustments include a $41 million tax benefit associated with a partial release of a valuation allowance on deferred tax assets based on market conditions, the tax effects on impairments and other charges, the impairment of an investment in Argentina, and Egypt currency impact.
(d)	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 the impairments and other charges, Egypt currency impact, and Argentina investment impairments, along with the tax adjustment, 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.
