Exhibit 99.1

HALLIBURTON ANNOUNCES THIRD QUARTER 2026 RESULTS

•Net income of $0.50 per diluted share and adjusted net income per diluted

share1 of $0.60.

•Revenue of $5.7 billion, operating margin of 10.9%, and adjusted operating

margin2 of 12.8%.

•Cash flow from operations of $368 million and free cash flow3 of $156 million.

•Approximately $250 million of share repurchases.

HOUSTON – October 20, 2026 – Halliburton Company (NYSE: HAL) announced today net

income attributable to company of $417 million, or $0.50 per diluted share, for the third

quarter of 2026 and adjusted net income attributable to company4, excluding impairments

and other charges and tax adjustments, of $501 million, or $0.60 per diluted share. This

compares to net income attributable to company for the second quarter of 2026 of $534

million, or $0.64 per diluted share, and adjusted net income attributable to company,

excluding impairments and other credits and tax adjustments, of $461 million, or $0.55 per

diluted share.

Adjusted EBITDA5, which excludes impairments and other charges, was $1.0 billion in the

third quarter of 2026, compared to adjusted EBITDA of $948 million in the second quarter of

2026.

Halliburton’s total revenue for the third quarter of 2026 was $5.7 billion, flat when compared

to total revenue in the second quarter of 2026. Operating income was $624 million in the

third quarter of 2026, compared to operating income of $778 million in the second quarter of

2026. Adjusted operating income6 in the third quarter of 2026, excluding impairments and

other charges, was $731 million, compared to adjusted operating income of $683 million in

the second quarter of 2026.

“I am pleased with Halliburton’s third quarter results. Our revenue exceeded our

expectations, and we took important steps towards improving our margins.” commented Jeff

Miller, Chairman, President and CEO.

“We are another three months into one of the largest energy disruptions in history. I expect

the work to restore production, rebuild inventories and strengthen energy security will drive

multi-year demand growth for oilfield services,

“Based on our early outlook for 2027, I expect mid-single digit revenue growth and operating

margins of about 15%, an approximately 200 basis point improvement. This outlook

assumes a flat North America market and does not require any recovery in North America

hydraulic fracturing. To us, that recovery is purely upside,” concluded Miller.

Operating Segments

Completion and Production

Completion and Production revenue in the third quarter of 2026 was $3.1 billion, a decrease

of $113 million, or 4% sequentially, while operating income was $457 million, a decrease of

$17 million, or 4% sequentially. These decreases were primarily driven by lower stimulation

activity in the Western Hemisphere and were partially offset by increased activity across

multiple product service lines in the Middle East.

Drilling and Evaluation

Drilling and Evaluation revenue in the third quarter of 2026 was $2.6 billion, an increase of

$102 million, or 4% sequentially, while operating income was $391 million, an increase of

$53 million, or 16% sequentially. These increases were primarily driven by improved activity

across multiple product service lines in the Middle East and Latin America, and increased

drilling related services in the Western Hemisphere. Partially offsetting these increases was

lower testing services internationally.

Geographic Regions

North America

North America revenue in the third quarter of 2026 was $2.2 billion, a decrease of 5%

sequentially. This decrease was primarily driven by lower pressure pumping services in U.S.

Land.

International

International revenue in the third quarter of 2026 was $3.5 billion, an increase of 3%

sequentially.

Latin America revenue in the third quarter of 2026 was $1.1 billion, flat sequentially. These

results were primarily driven by decreased stimulation activity in Argentina, offset by

increased activity across multiple product service lines in Mexico.

Europe/Africa revenue in the third quarter of 2026 was $1.0 billion, flat sequentially. These

results were primarily driven by decreased well construction activity in Namibia, offset by

increased activity across multiple product service lines in Nigeria.

Middle East/Asia revenue in the third quarter of 2026 was $1.4 billion, an increase of 8%

sequentially. These results were primarily driven by higher activity across multiple product

service lines in Saudi Arabia and Kuwait.

Other Financial Items

During the third quarter of 2026, Halliburton:

•Repurchased approximately $250 million of its common stock.

•Paid dividends of $0.17 per share.

•Spent $42 million on SAP S4 migration.

•Recognized a pre-tax charge of $107 million related to impairments and other

charges.

Selective Technology & Highlights

•Halliburton announced it secured an integrated well construction and completions

contract from Eni for the Cronos ultra-deepwater development in Block 6 of the

Cyprus Exclusive Economic Zone. The award strengthens Halliburton’s offshore

portfolio in the Eastern Mediterranean and expands the company’s role in the region’s

strategic natural gas development. Under the contract, Halliburton will deliver

integrated drilling, well construction, automation, and completions services for

exploration and development wells. The bundled scope reduces operational

interfaces, improves execution certainty, and supports efficient delivery for a multi-

year ultra-deepwater development.

•Halliburton announced it received an integrated contract by bp for the first appraisal

campaign in the Bumerangue field, offshore deepwater Brazil. The award includes a

comprehensive suite of services to fast-track the appraisal campaign for bp’s

discovery. The contract includes an integrated package of drilling services to optimize

reservoir evaluation and improve operational efficiency. The scope draws on

Halliburton’s drilling and evaluation portfolio to deliver an integrated execution model

for the drilling appraisal program. Halliburton reduces operational complexity through

consolidation of multiple services. LOGIX™ automation and remote operations will be

deployed to improve execution efficiency and consistency.

•Halliburton announced the signing of memorandums of understanding with Eneva

and WESCA to support energy development opportunities in Venezuela and help

customers advance projects in the country's oil and gas sector. With nearly nine

decades of experience in Venezuela, Halliburton helps customers advance projects

through strategically located bases in the country and by established operational

capabilities and local expertise. Halliburton and Eneva, one of Brazil’s leading

integrated energy companies and the country’s largest private natural gas operator,

will collaborate to identify and pursue development opportunities in Venezuela. The

agreement builds on the companies' existing relationship in Brazil.

•Halliburton announced the successful deployment of LOGIX™ automation and

remote operations on a deepwater exploration well with Eni offshore Indonesia. The

operation marks a series of industry and regional firsts that advance closed loop

drilling automation and demonstrate performance at scale in complex offshore

environments.

•Halliburton has entered into a multiyear agreement with Pampa Energía to support

the digital transformation of its unconventional operations in Vaca Muerta, one of the

world’s most significant shale plays. As regional development accelerates, the

agreement supports Pampa Energía’s strategy to scale efficiently, strengthen

decision-making, and deliver consistent execution within subsurface and operations

teams.

•Halliburton was awarded a multiyear agreement by Kuwait Oil Company (KOC) to

support the development of the Ahmadi Innovation Valley, a flagship initiative that

advances Kuwait’s energy sector transformation. The research and development

center will support KOC to deliver solutions in brownfield, greenfield, and

unconventional fields, address higher operational complexity, and build technology

designed for Kuwait’s upstream challenges. The center embeds applied research as

a permanent capability from concept through prototyping, piloting, and

commercialization.

•Halliburton Labs announced the addition of three companies to its collaborative

ecosystem: Electroflow, Osmoses, and SiTration. The selected ventures develop

breakthrough technologies that address critical challenges in battery materials,

resource recovery, and gas separations. These companies confront the material and

process bottlenecks that stand between today’s energy system and tomorrow's

opportunities. Halliburton Labs collaborates with early-stage, hard-tech ventures to

scale innovative technologies through industry expertise, world-class facilities, and a

global network of industrial and investment partners.

Adjusted net income per diluted share is a non-GAAP financial measure which is calculated 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 performance. See Reconciliation of Net Income

Attributable to Company to Adjusted Net Income Attributable to Company in Footnote Table 2.

(2)

Adjusted operating margin is a non-GAAP financial measure which is calculated by dividing

“Adjusted operating income” by “Total revenue.” Management believes adjusted operating margin

is useful to investors to assess and understand operating performance. See Reconciliation of

Operating Income to Adjusted Operating Income in Footnote Table 1.

(3)

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. See Reconciliation of Cash Flows from Operating Activities to Free Cash Flow in

Footnote Table 3.

(4)

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 adjusted net income 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 of

performance to identify underlying trends in the business and to establish operational goals. Total

adjustments remove the effect of these items. See Reconciliation of Net Income Attributable to

Company to Adjusted Net Income Attributable to Company in Footnote Table 2.

(5)

Adjusted EBITDA is a non-GAAP financial measure which is calculated as: “Net income,” before

“Interest expense, net,” “Income tax provision,” “Depreciation, depletion, and amortization,” and

excludes “Impairments and other charges (credits).” Management believes Adjusted EBITDA is a

key measure to assess and understand operating performance and is consistent with the

disclosures of Halliburton’s direct, large-cap competitors. See EBITDA, Adjusted EBITDA,

Related Margins, and Reconciliations schedule.

(6)

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. See Reconciliation

of Operating Income to Adjusted Operating Income in Footnote Table 1.

EBITDA and EBITDA margin are non-GAAP financial measures. EBITDA is calculated as “Net income” before “Interest

expense, net,” “Income tax provision” and “Depreciation, depletion, and amortization” for the respective periods. EBITDA

margin is calculated as “EBITDA” divided by “Total revenue.” Management believes EBITDA and EBITDA margin are key

measures to assess and understand operating performance and are consistent with the disclosures of Halliburton’s direct,

large-cap competitors.

(b)

For the three and nine months ended September 30, 2025, adjusted EBITDA excludes a $23 million impairment on an

investment in Argentina.

(c)

See Footnote Table 1 for details of the impairments and other charges (credits) recorded during the three and nine months

ended September 30, 2026 and 2025, and the three months ended June 30, 2026.

(d)

Adjusted EBITDA margin is a non-GAAP financial measure which is calculated as: “Adjusted EBITDA” divided by “Total

revenue.” Management believes Adjusted EBITDA margin is a key measure to assess and understand operating performance

and is consistent with disclosures of Halliburton's direct, large-cap competitors.

(a)

During the three months ended September 30, 2026, Halliburton recognized a pre-tax charge of $107 million primarily related

to $107 million of severance costs associated with the rationalization of our global headcount, and $25 million of inventory

costs and write-downs, partially offset by a $36 million gain resulting from the sale of a portion of our shares in an equity

investment.

During the three 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 three months ended September 30, 2025, Halliburton recognized a pre-tax charge of $392 million as a result of

severance costs, fixed and other assets write-offs, an impairment of assets held for sale, and other items.

(b)

During the nine months ended September 30, 2026, Halliburton recognized a pre-tax charge of $12 million primarily related to

$107 million of severance costs associated with the rationalization of our global headcount, partially offset by a $102 million

gain primarily related to a $54 million gain resulting from changes in our ownership interest in an equity investment and a $36

million gain resulting from the sale of a portion of our shares in an equity investment.

During the nine months ended September 30, 2025, Halliburton recognized a pre-tax charge of $748 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 and nine months ended September 30, 2026 and the three months ended June 30, 2026, the adjustment

includes the tax effect on impairments and other charges (credits). During the three and nine months ended September 30,

2025, 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 “One Big Beautiful Bill Act” (OBBBA), as well as the tax effect on impairments and other charges and the impairment of

an investment in Argentina.
