Reported net income of $0.92 per diluted share
Adjusted net income of $0.36 per diluted share
Cash flow from operating activities of $682 million and free cash flow of $478 million
First quarter dividend of $0.12 per share

Halliburton Company (NYSE:HAL) announced today net income of $824 million, or $0.92 per diluted share, for the fourth quarter of 2021. This compares to net income for the third quarter of 2021 of $236 million, or $0.26 per diluted share. Adjusted net income for the fourth quarter of 2021, excluding tax adjustments, was $320 million, or $0.36 per diluted share. This compares to adjusted net income for the third quarter of 2021, excluding special items, of $248 million, or $0.28 per diluted share. Halliburton's total revenue for the fourth quarter of 2021 was $4.3 billion compared to revenue of $3.9 billion in the third quarter of 2021. Reported operating income was $550 million in the fourth quarter of 2021 compared to reported operating income of $446 million in the third quarter of 2021. Reported operating income of $550 million in the fourth quarter of 2021 increased 20% compared to adjusted operating income of $458 million in the third quarter of 2021, excluding special items.

Total revenue for the full year of 2021 was $15.3 billion, an increase of $850 million, or 6% from 2020. Reported operating income for 2021 was $1.8 billion, compared to reported operating loss of $2.4 billion and adjusted operating income of $1.4 billion for 2020, excluding impairments and other charges.

"I am pleased with our solid execution in the fourth quarter and for the full year. Both operating divisions experienced revenue growth in the international and North America markets. Our Completion and Production division delivered solid mid-teens margins, and our Drilling and Evaluation division margins surprised to the upside," commented Jeff Miller, Chairman, President and CEO.

"Today's announcements of the dividend increase and debt retirement demonstrate my confidence in our business, customers, employees, and value proposition.

"I am excited about the accelerating multi-year upcycle. I expect the macro industry environment to remain supportive and the international and North America markets to continue their simultaneous growth.

"Halliburton uniquely benefits from this constructive environment. Our value proposition works, we have the right strategies for both international and North America markets, we are leaders in digital and automation, and we drive capital efficiency while advancing a sustainable energy future. I fully expect that Halliburton will accelerate cash flow generation, strengthen our balance sheet, and increase cash returns to shareholders in this upcycle," concluded Miller.

Operating Segments

Completion and Production

Completion and Production revenue in the fourth quarter of 2021 was $2.4 billion, an increase of $220 million, or 10%, when compared to the third quarter of 2021, while operating income was $347 million, an increase of $25 million, or 8%. These results were driven by higher completion tool sales globally, as well as increased pressure pumping services in North America land and the Middle East/Asia region. These improvements were partially offset by reduced stimulation activity in Latin America, Canada, and the Gulf of Mexico, lower pipeline services in Europe/Africa/CIS and Asia, reduced well intervention services in Brazil, and decreased artificial lift activity in North America land.

Drilling and Evaluation

Drilling and Evaluation revenue in the fourth quarter of 2021 was $1.9 billion, an increase of $197 million, or 11%, when compared to the third quarter of 2021, while operating income was $269 million, an increase of $83 million, or 45%. These results were due to increased drilling-related services globally, wireline sales in Guyana, improved project management activity in Ecuador and India, increased wireline activity in the Middle East/Asia region, and higher software sales in Latin America and Middle East/Asia. Partially offsetting these increases were decreased project management activity and testing services in Mexico, as well as lower drilling-related activity in Russia.

Geographic Regions

North America

North America revenue in the fourth quarter of 2021 was $1.8 billion, a 10% increase when compared to the third quarter of 2021. This increase was primarily driven by higher pressure pumping activity and drilling-related services in North America land, in addition to higher completion tool sales and fluid services in the Gulf of Mexico. These increases were partially offset by reduced stimulation activity in Canada and the Gulf of Mexico, coupled with reduced artificial lift activity in North America land.

International

International revenue in the fourth quarter of 2021 was $2.5 billion, an 11% increase when compared to the third quarter of 2021. This improvement was primarily driven by higher completion tool sales and software sales in all regions, increased activity across multiple product service lines in Norway, Brazil, and Egypt, increased well construction services and wireline activity in the Middle East/Asia region, improved project management activity in Ecuador and India, as well as increased drilling-related services in Mexico. Partially offsetting these increases were reduced activity in Russia, Mexico, and Vietnam.

Latin America revenue in the fourth quarter of 2021 was $669 million, a 7% increase sequentially. This improvement was driven by improved project management activity in Ecuador, increased drilling-related services in Mexico, increased activity across multiple product service lines in Brazil, wireline sales in Guyana, and higher activity across multiple product service lines in Colombia. These increases were partially offset by reduced project management activity, stimulation activity, and testing services in Mexico.

Europe/Africa/CIS revenue in the fourth quarter of 2021 was $730 million, an 8% increase sequentially. Higher software and completion tool sales across the region, improved activity across multiple product service lines in Norway and Egypt, and increased well control activity in Nigeria were partially offset by reduced activity in multiple product service lines in Russia, reduced pipeline services and well construction activity in the United Kingdom, and decreased stimulation activity in the Congo.

Middle East/Asia revenue in the fourth quarter of 2021 was $1.1 billion, a 16% increase sequentially, resulting from higher completion tool sales and wireline activity across the region, improved well construction services in Saudi Arabia and Oman, higher software sales in Kuwait and China, improved project management activity in India, and increased stimulation activity throughout Asia. These increases were partially offset by reduced pipeline services in Asia, along with lower activity across multiple product service lines in Vietnam.

Other Financial Items

Halliburton recognized a $409 million tax benefit, which included a gain of approximately $500 million due to the partial release of a valuation allowance on our deferred tax assets. This reversal is based on improved market conditions and reflects the Company's expectation to utilize these deferred tax assets.

Halliburton's board of directors has declared a 2022 first quarter dividend of twelve cents ($0.12) a share on the Company's common stock payable on March 23, 2022, to shareholders of record at the close of business on March 2, 2022.

(a)	During the three months ended December 31, 2020, Halliburton recognized a pre-tax charge of $446 million primarily related to a contemplated structured transaction for its North America real estate assets due to specific assets with a fair value less than the carrying amount. During the three months ended September 30, 2021, Halliburton closed that transaction, which resulted in a $74 million gain due to specific assets with a carrying amount less than the fair value. During the three months ended September 30, 2021, we also discontinued the proposed sale of our Pipeline and Process Services business leading to a depreciation catch-up related to these assets previously classified as held for sale. As a result, among these and other items, we recognized a $12 million pre-tax charge.
(b)	Management believes that operating income (loss) adjusted for impairments and other charges for the three months ended December 31, 2020 and September 30, 2021, 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. Adjusted operating income is calculated as: "As reported operating income (loss)" plus "Total impairments and other charges" for the respective periods.

Reconciliation of As Reported Net Income (Loss) to Adjusted Net Income
(Millions of dollars and shares except per share data)
(Unaudited)

		Three Months Ended
		December 31						September 30
		2021			2020			2021
As reported net income (loss) attributable to company		$	824		$	(235	)	$	236

Adjustments:
Impairments and other charges			—			446			12
Total adjustments, before taxes			—			446			12
Tax benefit (a)			(504	)		(51	)		—
Total adjustments, net of taxes (b)			(504	)		395			12
Adjusted net income attributable to company (b)		$	320		$	160		$	248

Diluted weighted average common shares outstanding			896			885			894
As reported net income (loss) per diluted share (c)		$	0.92		$	(0.27	)	$	0.26
Adjusted net income per diluted share (c)		$	0.36		$	0.18		$	0.28

(a)	During the three months ended December 31, 2021, based on improved market conditions, Halliburton recognized a $504 million tax benefit, primarily associated with a partial release of a valuation allowance on its deferred tax assets. During the three months ended December 31, 2020, the tax benefit in the table above includes the tax effect on impairments and other charges.
(b)	Management believes that net income (loss) adjusted for impairments and other charges and the tax benefit, 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. Adjusted net income attributable to company is calculated as: "As reported net income (loss) attributable to company" plus "Total adjustments, net of taxes" for the respective periods.
(c)	As reported net income (loss) per diluted share is calculated as: "As reported net income (loss) attributable to company" divided by "Diluted weighted average common shares outstanding." Adjusted net income per diluted share is calculated as: "Adjusted net income attributable to company" divided by "Diluted weighted average common shares outstanding."

		Year Ended

Noncontrolling interest equipment impairments			—			(9	)
Total adjustments, before taxes			12			3,958

As reported net income (loss) per diluted share (d)		$	1.63		$	(3.34	)
Adjusted net income per diluted share (d)		$	1.08		$	0.65

(a)	During the years ended December 31, 2021 and 2020, based on changing market conditions during each period, Halliburton recognized a $504 million tax benefit and a $310 million tax expense, respectively, associated with a valuation allowance on its deferred tax assets. During the year ended December 31, 2020, the tax benefit in the table above includes the tax effect on impairments and other charges.
(b)	Management believes that net income (loss) adjusted for the loss on early extinguishment of debt and impairments and other charges, along with the associated noncontrolling interest, and the tax benefit, 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. Adjusted net income attributable to company is calculated as: "As reported net income (loss) attributable to company" plus "Total adjustments, net of taxes" for the respective periods.
(c)	For the year ended December 31, 2020, as reported diluted weighted average common shares outstanding excludes one million shares associated with stock-based compensation plans as the impact is antidilutive since Halliburton's reported income attributable to company was in a loss position during the period. When adjusting income attributable to company in that period for the adjustments discussed above, these shares become dilutive.
(d)	As reported net income (loss) per diluted share is calculated as: "As reported net income (loss) attributable to company" divided by "As reported diluted weighted average common shares outstanding." Adjusted net income per diluted share is calculated as: "Adjusted net income attributable to company" divided by "Adjusted diluted weighted average common shares outstanding."

HALLIBURTON COMPANY
Reconciliation of Cash Flows from Operating Activities to Free Cash Flow
(Millions of dollars)
(Unaudited)

		Year Ended						Three Months Ended
		December 31						December 31
		2021			2020			2021
Total cash flows provided by operating activities		$	1,911		$	1,881		$	682
Capital expenditures			(799	)		(728	)		(316	)
Proceeds from sales of property, plant, and equipment			257			286			112
Free cash flow (a)		$	1,369		$	1,439		$	478

(a)	The Free Cash Flow metric 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 our direct, large-cap competitors. Prior periods presented are consistent with this metric.
