Segment Reporting [Abstract]

Business Segments and Geographic Areas

16. Business Segments and Geographic Areas

The Company is comprised of 16 business units to provide products and services to the energy industry. Each of the business units is managed by a business unit president, recognizes revenue, incurs expenses, and has discrete financial information readily available. The business units are aggregated into our 2 reportable segments, Energy Products and Services, and Energy Equipment, based on the products and services provided, customer base, and operating environment. The reportable segments are led by Segment Presidents, who are responsible for oversight of the business units’ strategy and performance. The Segment Presidents report directly to the CEO and provide monthly operating and financial updates.

The CEO has final authority over resource allocation decisions and performance assessment for the Company. Consequently, the CEO has been identified as the CODM. The CODM regularly receives information directly from the Segment Presidents as well as the

business units. However, for decision-making purposes related to the assessment of performance and allocation of resources, the CODM uses financial information at the segment level. The CODM regularly reviews Operating Profit for each segment to assess performance and for resource allocation decisions in the annual budgeting process and in the quarterly performance review processes.

Energy Products and Services

The Company’s Energy Products and Services segment primarily designs, manufactures, rents, and sells products and equipment used in drilling, intervention, completion, and production activities. Products include drill bits, downhole tools, premium drill pipe, drilling fluids, integral and weld-on connectors for conductor strings and surface casing, completion tools, and artificial lift systems. The segment also designs, manufactures, and delivers high-end composite pipe, tanks, and structures engineered to solve both corrosion and weight challenges in a wide variety of applications, including oil and gas, chemical, industrial, wastewater, fuel handling, marine and offshore, and rare earth mineral extraction.

In addition to product and equipment sales, the segment provides services, software, and digital solutions to improve drilling and completion operational performance. Services include tubular inspection and coating, solids control, waste management. Software and digital solutions offered include drilling and completion optimization and remote monitoring (via downhole and surface instrumentation), wired drill pipe services, software controls and applications, and data management and analytics services at the edge and in the cloud.

Energy Products and Services serves oil and gas companies, drilling contractors, oilfield service companies, oilfield equipment rental companies and developers of geothermal energy. Demand for the segment’s products and services primarily depends on the level of oilfield drilling activity by oil and gas companies, drilling contractors, and oilfield service companies. Demand for the segment’s composite solutions serving applications outside of oil and gas are driven by industrial activity, infrastructure spend, and population growth.

Energy Equipment

The Company’s Energy Equipment segment manufactures and supports the capital equipment and integrated systems needed for oil and gas exploration and production, both onshore and offshore, as well as for other marine-based, industrial and renewable energy markets.

The segment designs, manufactures, and integrates technologies for drilling and producing oil and gas wells. This includes equipment and technologies needed for drilling, including land rigs, offshore drilling equipment packages, drilling rig components, managed pressure drilling, and software control systems that mechanize and automate the drilling process and rig functionality; hydraulic fracture stimulation; well intervention, including coiled tubing units, coiled tubing, and wireline units and tools; cementing products; onshore production, including fluid processing, and surface transfer as well as progressive cavity pumps; offshore production, including integrated production systems and subsea production technologies; and aftermarket support of these technologies, providing spare parts, service, and repair.

Energy Equipment primarily serves contract drillers, oilfield service companies, and oil and gas companies. Demand for the segment’s products primarily depends on capital spending plans by drilling contractors, service companies, and oil and gas companies, and secondarily on the overall level of oilfield drilling, completions, and workover activity which drives demand for equipment, spare parts, service, and repair for the segment’s large installed base of equipment.

The segment also serves marine and offshore markets, where it designs and builds equipment for wind turbine installation and cable lay vessels, and offers heavy lift cranes and jacking systems; industrial markets, where the segment provides pumps and mixers for a wide breadth of industrial end markets; and other renewable energy markets, where it is applying its gas processing expertise to provide solutions that aid in wind power development, hydrogen production and carbon sequestration.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Basis of Presentation

1. Organization and Basis of Presentation

Nature of Business

We design, construct, manufacture and sell comprehensive systems, components, and products used in oil and gas drilling and production and certain industrial and renewable energy sectors. We also provide technology and oilfield services and supplies, distribute products and provide supply chain integration services to the upstream oil and gas industry. Our revenues and operating results are directly related to the level of worldwide oil and gas drilling and production activities and the profitability and cash flow of oil and gas companies, drilling contractors and oilfield service companies, which in turn are affected by current and anticipated prices of oil and gas. Oil and gas prices have been, and are likely to continue to be, volatile.

Basis of Consolidation

The accompanying Consolidated Financial Statements include the accounts of NOV Inc. and its consolidated subsidiaries. Certain reclassifications have been made to the prior year financial statements for them to conform with the 2025 presentation. All significant intercompany transactions and balances have been eliminated in consolidation. Investments that are not wholly owned, but where we exercise control, are fully consolidated with the equity held by minority owners and their portion of net income (loss) reflected as noncontrolling interests in the accompanying consolidated financial statements. Investments in unconsolidated affiliates, over which we exercise significant influence, but not control, are accounted for by the equity method.

Accumulated goodwill impairment was $7,301 million as of December 31, 2025.

Identified intangible assets with determinable lives consist primarily of customer relationships, trademarks, trade names, patents, and technical drawings acquired in acquisitions, and are being amortized in a manner consistent with the underlying cash flows over the estimated useful lives of 2-40 years. Amortization expense of identified intangibles is expected to be approximately $51 million, $47 million, $39 million, $28 million, and $24 million for the next five years.

The net book values of identified intangible assets are identified by segment as follows (in millions):

Goodwill represents the excess of acquisition price paid over the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed. Goodwill and intangibles with indefinite lives are not amortized. Goodwill is assigned to the reporting units that are expected to benefit from the synergies of a business combination. The recoverability of goodwill and indefinite-lived intangibles is assessed annually, or more frequently whenever events or circumstances indicate they might be impaired.

The Company has the option to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit or indefinite lived intangible asset is greater than its carrying amount. If the qualitative assessment indicates that it is more likely than not that the fair value of a reporting or indefinite lived intangible asset is greater than its carrying amount, no further testing is required. However, if the Company concludes otherwise, then it is required to perform a quantitative assessment.

For the year ended December 31, 2025, the Company elected to bypass the qualitative assessment and proceed directly to a quantitative goodwill impairment test for each reporting unit. When the Company performs a quantitative assessment, it compares the reporting unit’s carrying value to the respective fair value. Fair value of the reporting unit is determined using significant unobservable inputs, or level 3 in the fair value hierarchy. These inputs are based on internal management estimates, forecasts and judgments, using discounted cash flow. The discounted cash flow is based on management’s forecast of operating performance for the reporting unit. The two main assumptions used in measuring goodwill impairment, which bear the risk of change and could impact the Company’s goodwill impairment analysis, include the cash flows from operations from each reporting unit and its weighted average cost of capital. The starting point for each of the reporting unit’s cash flows from operations is the detailed annual plan or updated forecast. Cash flows beyond the updated forecasted operating plans are estimated using a terminal value calculation, which incorporates historical and forecasted financial cyclical trends for each reporting unit and considered long-term earnings growth rates. The financial and credit market volatility directly impacts our fair value measurement through our weighted average cost of capital that we use to determine our discount rate. During times of volatility, significant judgment must be applied to determine whether credit changes are a short-term or long-term trend. The quantitative analysis for indefinite lived intangible assets is performed similarly using an income approach.

Management reviews finite-lived intangibles for indicators of impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Cash flows expected to be generated by the finite-lived intangibles are estimated over the intangible asset’s useful life based on updated projections on an undiscounted basis. If the evaluation indicates that the carrying value of the finite-lived intangible asset may not be recoverable, the potential impairment is measured at fair value.

During the fourth quarter of 2025, the Company performed its annual impairment test, as described in ASC Topic 350, as of October 1, 2025. Based on the results of the assessment, the Company concluded that the estimated fair value of its Renewables reporting unit was below its carrying amount. As a result, the Company recorded a goodwill impairment charge of $40 million related to the Renewables reporting unit during the year ended December 31, 2025.

The goodwill impairment charge was recognized within “Goodwill and long-lived asset impairment” in the Consolidated Statements of Income. Following the impairment, the Renewables reporting unit has no remaining goodwill balance.

No goodwill impairment was identified for the Company’s other reporting units as part of the annual impairment test performed as of October 1, 2025. However, the estimated fair values of certain reporting units were not significantly in excess of their respective carrying amounts (excess fair value of 15%), and these reporting units had an aggregate goodwill balance of approximately $313 million as of December 31, 2025. A deterioration in market conditions, adverse changes in operating performance, or an increase in the Company’s cost of capital could result in future goodwill impairment charges for one or more of these reporting units.

In addition, the Company completed its annual impairment test of its indefinite-lived intangible assets as of October 1, 2025. Based on the results of this assessment, the Company concluded that the estimated fair values of its indefinite-lived intangible assets exceeded their respective carrying amounts, and accordingly, no impairment charges were recorded for indefinite-lived intangible assets during the year ended December 31, 2025.

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Fair Value of Financial Instruments

The carrying amounts of financial instruments including cash and cash equivalents, receivables, and payables approximated fair value because of the relatively short maturity of these instruments. Cash equivalents include only those investments having a maturity date of three months or less at the time of purchase.

Derivative Financial Instruments

The Company records all derivative financial instruments at their fair value in its Consolidated Balance Sheet. Except for certain non-designated hedges discussed in Note 3 below, all derivative financial instruments that the Company holds are designated as cash flow hedges and are highly effective in offsetting movements in the underlying risks. Such arrangements typically have terms between two and 24 months but may have longer terms depending on the underlying cash flows being hedged, typically related to the projects in our backlog.

Inventories

Inventories are stated at the lower of cost or estimated net realizable value using the first-in, first-out or average cost methods. Inventories consist of raw materials and supplies, work-in-process and finished goods and purchased products. The Company reviews historical usage of inventory on-hand, assumptions about future demand and market conditions, and estimates about potential alternative uses, which are limited, to estimate net realizable value. The Company evaluates inventory using the best information available at the time to inform our assumptions and estimates about future demand and resulting sales volumes, and records reserves as necessary.

We recorded charges to inventory reserves of $36 million, $31 million, and $28 million for the years ended December 31, 2025, 2024, and 2023, respectively. At December 31, 2025 and 2024, inventory reserves totaled $261 million and $286 million, or 12.7% and 12.9% of gross inventory, respectively.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Expenditures for major improvements that extend the lives of property and equipment are capitalized while minor replacements, maintenance and repairs are charged to operations as incurred. Disposals are removed at cost less accumulated depreciation with any resulting gain or loss reflected in operations. Depreciation is provided using the straight-line method over the estimated useful lives of individual items. Depreciation expense was $300 million, $294 million, and $260 million for the years ended December 31, 2025, 2024 and 2023, respectively. The estimated useful lives of the major classes of property, plant and equipment are included in Note 5 to the Consolidated Financial Statements.

We record impairment losses on long-lived assets used in operations when events and circumstances indicate that the assets are impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. The carrying value of assets used in operations that are not recoverable is reduced to fair value if lower than carrying value. In determining the fair market value of the assets, we consider market trends and recent transactions involving sales of similar assets, or when not available, discounted cash flow analysis.

Acquisitions and Investments

Acquisitions of businesses are accounted for using the acquisition method of accounting, and the financial statements include the results of the acquired operations from the respective dates of acquisition.

The acquisition price of the acquired entities is preliminarily allocated to the net assets acquired and liabilities assumed based on the estimated fair value at the dates of acquisition, with any excess of acquisition price paid over the fair value of net assets acquired, including intangibles, recognized as goodwill. Subsequent changes to preliminary amounts are made prospectively.

There were no acquisitions for the year ended December 31, 2025. The Company paid cash of $298 million and $22 million, net of cash acquired, for acquisitions for the years ended December 31, 2024 and 2023, respectively.

Foreign Currency

The functional currency for most of our foreign operations is the local currency. However, certain foreign operations, including our operations in Norway, use the U.S. dollar as the functional currency. The cumulative effects of translating the balance sheet accounts from the functional currency into the U.S. dollar at current exchange rates are included in accumulated other comprehensive income (loss). Revenues and expenses are translated at average exchange rates in effect during the period. Accordingly, financial statements of these foreign subsidiaries are remeasured to U.S. dollars for consolidation purposes using current rates of exchange for monetary assets and liabilities and historical rates of exchange for nonmonetary assets and related elements of expense. Revenue and expense elements are remeasured at rates that approximate the rates in effect on the transaction dates. For all operations, gains or losses from remeasuring foreign currency transactions into the functional currency are included in income. Net foreign currency transaction losses were $55 million, $19 million, and $84 million for the years ending December 31, 2025, 2024 and 2023, respectively, and are included in other expenses, net, in the accompanying Consolidated Statements of Income.

Revenue Recognition

The majority of the Company’s revenue streams record revenue at a point in time when a performance obligation has been satisfied by transferring control of promised goods or services to a customer. Products are sold or rented and services are provided based upon a fixed or determinable price and do not generally include right of return or other significant post-delivery obligations. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities. Payment terms and conditions vary by contract type. We have elected to apply the practical expedient that does not require an adjustment for a financing component if, at contract inception, the period between when we transfer the promised goods or service to the customer and when the customer pays for the goods or service is one year or less. Shipping and handling costs are recognized when incurred and are treated as costs to fulfill the original performance obligation instead of as a separate performance obligation.

Revenue is generated from contracts that may include multiple performance obligations. The Company considers the degree of customization, integration and interdependency of the related products and services when assessing distinct performance obligations within one contract. Stand-alone selling price (“SSP”) for each distinct performance obligation is generally determined using the price at which the products and services would be sold separately to the customer. Discounts, when provided, are allocated based on the relative SSP of the various products and services.

For revenue that is not recognized at a point in time, the Company follows accounting guidance for revenue recognized over time, as follows:

Revenue Recognition under Long-term Construction Contracts

Revenue is recognized over-time for certain long-term construction contracts in the Energy Equipment segment. These contracts include custom designs for customer-specific applications that are unique and require significant engineering efforts. Revenue is recognized as work progresses on each contract. Right to payment is enforceable for performance completed to date, including a reasonable profit.

Because of control transferring over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. We generally use the cost-to-cost (input) measure of progress for our contracts because it best depicts the transfer of assets to the customer which occurs as we incur costs. Under the cost-to-cost measure of progress, progress towards completion of each contract is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. These costs include labor, materials, subcontractors’ costs, and other direct costs. Any expected losses on a project are recorded in full in the period in which the loss becomes probable.

These long-term construction contracts generally include integrating a complex set of tasks and components into a single project or capability, so they are accounted for as one performance obligation.

Estimating total revenue and cost at completion of long-term construction contracts is complex, subject to many variables and requires significant judgment. It is common for our long-term contracts to contain late delivery fees, work performance guarantees, and other provisions that can either increase or decrease the transaction price. We estimate variable consideration as the most likely amount we expect to receive. We include variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur, or when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based on an assessment of our anticipated performance and historical, current and forecasted information that is reasonably available to us. Net revenue recognized from performance obligations satisfied in previous periods was $5 million and $19 million for the years ended December 31, 2025 and 2024, respectively, primarily due to change orders.

Service and Repair Work

For service and repair contracts, revenue is recognized over time. We generally use the output method to measure progress on service contracts due to the manner in which the customer receives and derives value from the services provided. For repair contracts, we generally use the cost-to-cost measure of progress because it best depicts the transfer of assets to the customer.

Remaining Performance Obligations

Remaining performance obligations represent the transaction price of firm orders for all revenue streams for which work has not been performed on contracts with an original expected duration of one year or more. We do not disclose the remaining performance obligations of royalty contracts, service contracts for which there is a right to invoice, and short-term contracts that are expected to have a duration of one year or less.

As of December 31, 2025, the aggregate amount of the transaction price allocated to remaining performance obligations was $4,775 million. Although numerous factors can affect timing of revenue recognized on performance obligations, such as customer change orders and supplier accelerations or delays, the Company expects to recognize approximately $2,011 million in revenue for the remaining performance obligations in 2026, $1,197 million in 2027, $431 million in 2028, and $1,136 million thereafter.

Costs to Obtain and Fulfill a Contract

We recognize an asset for the incremental costs of obtaining a contract, such as sales commissions, with a customer when we expect the benefit of those costs to be longer than one year. Costs to fulfill a contract, such as set-up and mobilization costs, are also capitalized when we expect to recover those costs. These contract costs are deferred and amortized over the period of contract performance. Total capitalized costs to obtain and fulfill a contract and the related amortization were immaterial during the periods presented and are included in other current and long-term assets on our Consolidated Balance Sheets. We apply the practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less.

Service and Product Warranties

The Company provides service and warranty policies on certain of its products. The Company accrues liabilities under service and warranty policies based upon specific claims and a review of historical warranty and service claim experience. Adjustments are made to accruals as claim data and historical experience change. In addition, the Company incurs discretionary costs to service its products in connection with product performance issues and accrues for them when they are encountered. The Company monitors the actual cost of performing these discretionary services and adjusts the accrual based on the most current information available.

The changes in the carrying amount of service and product warranties are as follows (in millions):


Balance at December 31, 2023	$	72
Net provisions for warranties issued during the year		22
Amounts incurred		(27	)
Currency translation adjustments and other		1
Balance at December 31, 2024	$	68
Net provisions for warranties issued during the year		29
Amounts incurred		(31	)
Currency translation adjustments and other		2
Balance at December 31, 2025	$	68

Income Taxes

The liability method is used to account for income taxes. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates that will be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to amounts which are more likely than not to be realized.

Concentration of Credit Risk

We grant credit to our customers, which operate primarily in the oil and gas industry. Concentrations of credit risk are limited because we have many geographically diverse customers, thus spreading trade credit risk. We control credit risk through credit evaluations, credit limits and monitoring procedures. We perform periodic credit evaluations of our customers’ financial condition and generally do not require collateral but may require letters of credit for certain international sales. Credit losses are provided for in the financial statements. Allowances for credit losses are determined based on a continuous process of assessing the Company’s portfolio on an individual customer basis considering current market conditions and trends. This process consists of a review of historical collection experience, current aging status of the customer accounts, and financial condition of the Company’s customers. Based on a review of these factors, the Company will establish or adjust allowances for specific customers. As of December 31, 2025 and 2024, the allowance for credit losses totaled $64 million and $67 million, respectively.

Stock-Based Compensation

Compensation expense for the Company’s stock-based compensation plans is measured using the fair value method. The fair value of stock option grants and restricted stock is amortized to expense using the straight-line method over the shorter of the vesting period or the remaining employee service period.

The Company provides compensation benefits to employees and non-employee directors under share-based payment arrangements, including various employee stock option plans.

Environmental Liabilities

When environmental assessments or remediations are probable and the costs can be reasonably estimated, remediation liabilities are recorded on an undiscounted basis and are adjusted as further information develops or circumstances change.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect reported and contingent amounts of assets and liabilities as of the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Such estimates include but are not limited to, estimated losses on accounts receivable, estimated costs and related margins of projects accounted for over time, estimated realizable value on excess and obsolete inventory, contingencies, estimated liabilities for litigation and environmental exposures and liquidated damages, estimated warranty costs, estimates related to pension accounting, estimates related to the fair value of reporting units for purposes of assessing goodwill and other indefinite-lived intangible assets for impairment and estimates related to valuation allowances on deferred tax assets. Actual results could differ from those estimates.

Contingencies

The Company accrues for costs relating to litigation claims and other contingent matters, including liquidated damage liabilities, when such liabilities become probable and reasonably estimable. In circumstances where the most likely outcome of a contingency can be reasonably estimated, we accrue a liability for that amount. Where the most likely outcome cannot be estimated, a range of potential losses is established and if no one amount in that range is more likely than others, the low end of the range is accrued. Such estimates may be based on advice from third parties or on management’s judgment, as appropriate. Revisions to contingent liabilities are reflected in income in the period in which different facts or information become known or circumstances change that affect the Company’s previous judgments with respect to the likelihood or amount of loss. Amounts paid upon the ultimate resolution of contingent liabilities may be materially different from previous estimates and could require adjustments to the estimated reserves to be recognized in the period such new information becomes known.

Net Income Attributable to Company Per Share

The following table sets forth the computation of weighted average basic and diluted shares outstanding (in millions, except per share data):


	Year Ended December 31,
	2025		2024		2023
Numerator:
Net income attributable to Company	$	145	$	635	$	993
Denominator:
Basic—weighted average common shares outstanding		372		392		393
Dilutive effect of employee stock options and other unvested stock awards		3		4		4
Diluted—weighted average common shares outstanding		375		396		397

Net income attributable to Company per share:
Basic	$	0.39	$	1.62	$	2.53
Diluted	$	0.39	$	1.60	$	2.50

Cash dividends per share	$	0.51	$	0.275	$	0.20

Net income attributable to Company allocated to participating securities was immaterial for the years ended December 31, 2025, 2024 and 2023 and therefore not excluded from net income attributable to Company per share calculation. The Company had stock options and restricted shares outstanding that were anti-dilutive totaling 15 million, 16 million, and 18 million at December 31, 2025, 2024 and 2023, respectively.

Recently Issued Accounting Standards

In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures” (“ASU 2024-03”), which improves the disclosures required for certain expense captions in the Company’s annual and interim consolidated financial statements. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027. The Company is currently evaluating the impact of this standard on its disclosures.

Recently Adopted Accounting Standards

The Company adopted ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), on a prospective basis effective for the fiscal year ended December 31, 2025. The amendments in ASU 2023-09 enhance transparency and usefulness of income tax disclosures, primarily related to the rate reconciliation and income taxes paid.

Cash dividends aggregated $190 million and $108 million for the years ended December 31, 2025 and 2024, respectively. The declaration and payment of future dividends is at the discretion of the Company’s Board of Directors and will be dependent upon the Company’s results of operations, financial condition, capital requirements and other factors deemed relevant by the Company’s Board of Directors.

Total compensation cost that has been charged against income for all share-based compensation arrangements was $67 million, $70 million and $66 million for 2025, 2024 and 2023, respectively. The total income tax benefit (expense) recognized before consideration of valuation allowance in the Consolidated Statements of Income for all share-based compensation arrangements was $(1) million, $2 million and $7 million for 2025, 2024 and 2023, respectively.

The Company’s stock-based compensation plan, known as the NOV Inc. Long-Term Incentive Plan (the “NOV Plan”), was approved by shareholders on May 11, 2018 and amended and restated on May 24, 2022 and May 20, 2025. The NOV Plan provides for the granting of stock options, restricted stock, restricted stock units, performance awards, phantom shares, stock appreciation rights, stock payments and substitute awards. The number of shares authorized under the NOV Plan is 70.9 million. The NOV Plan is also subject to a fungible ratio concept, such that the issuance of stock options and stock appreciation rights reduces the number of available shares under the NOV Plan on a 1-for-1 basis, and the issuance of other awards reduces the number of available shares under the NOV Plan on a 1.5-for-1 basis. At December 31, 2025, approximately 17.2 million shares remained available for future grants under the NOV Plan.

The Company also has outstanding awards under its other stock-based compensation plan known as the National Oilwell Varco, Inc. Long-Term Incentive Plan (the “Plan”), however the Company is no longer granting new awards under the Plan. The Plan provides for the granting of stock options, performance-based share awards, restricted stock, phantom shares, stock payments and stock appreciation rights (“SARs”). The number of shares authorized under the Plan is 69.4 million. The Plan is subject to a fungible ratio concept, such that the issuance of stock options and SARs reduces the number of available shares under the Plan on a 1-for-1 basis, and the issuance of other awards reduces the number of available shares under the Plan on a 3-for-1 basis.

Stock Options

Options granted under our stock-based compensation plans generally vest over a three-year period starting one year from the date of grant and expire ten years from the date of grant. The purchase price of options granted may not be less than the closing market price of NOV common stock on the date of grant.

Stock option information summarized below includes amounts for the NOV Plan and the Plan and stock plans of acquired companies. Options outstanding at December 31, 2025 under the stock option plans have exercise prices between $15.00 and $38.86 per share, and expire at various dates from February 25, 2026 to February 20, 2035.

The following summarizes information about stock options outstanding at December 31, 2025:


	Weighted-Avg		Options Outstanding				Options Exercisable
	Remaining				Weighted-Avg				Weighted-Avg
Range of Exercise Price	Contractual Life		Shares		Exercise Price		Shares		Exercise Price
$15.00 - $25.00		6.19		6,554,523	$	17.84		5,007,470	$	17.91

Total		3.36		14,918,885	$	26.79		13,371,832	$	27.84

As of December 31, 2025, the weighted-average remaining contractual term for outstanding and exercisable stock options was 3.36 years and 2.79 years, respectively. The aggregate intrinsic value of outstanding options as of December 31, 2025, was zero.

The weighted-average fair value of options granted during 2025, 2024 and 2023, was approximately $6.67, $7.90, and $9.75 per share, respectively, as determined using the Black-Scholes option-pricing model. The total intrinsic value of options exercised was zero during 2025 and $1 million during 2024.

The determination of fair value of share-based payment awards on the date of grant using an option-pricing model is affected by our stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, the expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise activity. The use of the Black Scholes model requires the use of actual employee exercise activity data and the use of a number of complex assumptions including expected volatility, risk-free interest rate, expected dividends and expected term.


	Year Ended December 31,
Valuation Assumptions:	2025			2024			2023
Expected volatility		47.1	%		46.8	%		45.7	%
Risk-free interest rate		4.4	%		4.0	%		4.1	%
Expected dividend yield		2.0	%		1.1	%		0.9	%
Expected term (in years)		6.6			6.0			5.8

The Company used the actual volatility for traded options for the past 10 years prior to option date as the expected volatility assumption required in the Black Scholes model.

The risk-free interest rate assumption is based upon observed interest rates appropriate for the term of our employee stock options. The dividend yield assumption is based on the history and expectation of dividend payouts. The estimated expected term is based on actual employee exercise activity for the past ten years. Forfeitures are accounted for as they occur.

At December 31, 2025, total unrecognized compensation cost related to nonvested stock options was $6 million. This cost is expected to be recognized over a weighted-average period of three years. The total fair value of stock options vested in 2025, 2024 and 2023 was approximately $9 million for each year. Cash received from option exercises for 2025 was zero, and $3 million and $4 million in 2024 and 2023, respectively. The actual tax benefit (expense) realized for the tax deductions from share-based compensation was zero in 2025, 2024, and 2023.

Stock Appreciation Rights

On December 20, 2017, the Company made a tender offer to exchange SARs issued to certain employees on February 24, 2016 (“2016 SARs”) for cash, amended SARs, and new stock options. The transaction was structured to provide the employees an equal long-term incentive compensation value, while alleviating volatility in the Company’s earnings caused by required mark-to-market accounting on outstanding SARS. Of the outstanding 2016 SARs, 94.75% were exchanged resulting in a total cash payment of $14 million and granting of 3,613,707 new stock options on the exchange date with an exercise price of $34.32 and a fair value of $8.47, with vesting matched to the exchanged 2016 SARs.

The following summary presents information regarding outstanding SARs:


	Year Ended December 31,
	2025					2024
	Number			Average		Number			Average
	of			Exercise		of			Exercise
	Shares			Price		Shares			Price
Shares under SARs at beginning of year		1,021,557		$	28.36		1,056,805		$	28.37

The Company recognized no expense related to SARs in 2025, 2024, or 2023. There was no liability for cash-settled SARs at December 31, 2025.

Restricted Shares

The Company issues restricted stock units (“RSUs”) and performance share awards (“PSAs”) to officers and key employees in addition to stock options. On February 19, 2025, under the NOV Plan, the Company granted 526,425 stock options with a fair value of $6.67 per option and an exercise price of $15.28 per share; 3,214,507 RSUs with a fair value of $15.28 per share; and PSAs to senior management employees with potential payouts varying from zero to 1,217,278 shares. On March 6, 2025, the Company granted 750 RSUs with a grant price of $14.35. On March 20, the Company granted 82,781 RSUs with a grant price of $15.10 per share; and PSAs to senior management employees with potential payouts varying from zero to 152,316 shares. The stock options vest over a three-year period from the grant date. The RSUs vest in three equal annual installments commencing on the first anniversary of the grant date. The 2025 PSAs can be earned based on performance against two established goals over a three-year period: 85% with a TSR (total shareholder return) goal and 15% with an internal NVA (“NOV Value Added”, a return on capital metric) goal. TSR performance is determined by comparing the Company’s TSR with the TSR of the members of the Philadelphia Stock Exchange’s Oil Services Sector Index (OSX) for the three-year performance period. The TSR portion of the performance share awards is subject to a vesting cap equal to 100% of Target Level if the Company’s absolute TSR is negative, regardless of relative TSR results. Conversely, if the Company’s absolute TSR is greater than 15% annualized over the three-year performance period the payout amount shall not be less than 50% of Target Level, regardless of relative TSR results. The NVA goal is based on the Company’s improvement in NVA from the beginning of the performance period until the end of the performance period. NVA is calculated as an amount equal to the Company’s (a) gross cash earnings less (b) average gross operating assets times an amount equal to a required return on assets, with certain adjustments.

On April 28, 2025, the Company granted 1,839 restricted stock units with a fair value of $12.24 per share. The awards were granted to employees and vest in three equal annual installments commencing on the first anniversary of grant date.

On May 20, 2025 the Company granted 127,592 restricted stock units with a fair value of $12.54 per share. The awards were granted to non-employee members of the board of directors and vest on the first anniversary of the grant date.

The Company did not have any customers with revenues greater than 10% of total revenue for the years ended December 31, 2025, 2024, or 2023.

Contract Assets and Liabilities

Contract assets include unbilled amounts when revenue recognized exceeds the amount billed to the customer under contracts where revenue is recognized over-time. There were no impairment losses recorded on contract assets for the years ending December 31, 2025, 2024 and 2023.

Contract liabilities consist of advance payments, billings in excess of revenue recognized and deferred revenue.

The changes in the carrying amount of contract assets and contract liabilities are as follows (in millions):


	Contract Assets			Contract Liabilities
Balance at December 31, 2024	$	577		$	492
Billings		(1,838	)		1,586

Currency translation adjustments and other		44			32
Balance at December 31, 2025	$	596		$	565

Royalty Revenue

The Company recognizes royalty revenue due under various licenses for the Company’s intellectual property, including for technology related to drill bits. The Company recognized revenue for drill bit licenses of approximately $57 million, $67 million, and $78 million for years ended December 31, 2025, 2024, and 2023, respectively. As previously disclosed, the Company is currently pursuing litigation against certain non-paying licensees, which will impact our ability to collect the receivables timely. Effective October 1, 2025, we stopped recording royalty revenue due to increasing difficulty to reasonably estimate the amount of revenue given the length of time since the licensee’s last royalty payment, however, the Company believes it is entitled to royalty payments beyond the third quarter of 2025. As of December 31, 2025, royalty receivables of $133 million, net of related reserves of $78 million and the remaining timing related discount of $47 million, are included in “Other assets” on the Consolidated Balance Sheets. The Company’s revenue recognition in accordance with generally accepted accounting principles, including the reserves and discounts discussed above, do not impact the amount the Company is entitled to recover on its claims from the licensees in litigation. While we continue to believe it is probable the Company will collect all or substantially all of the consideration to which it is entitled pursuant to the terms of the licensing agreements, the Company will also continue to evaluate the collectability of the receivables in accordance with the policy described in Note 2. See Note 12 to the Consolidated Financial Statements for discussion of the ongoing litigation.

Allowance for Credit Losses

The Company estimates its allowance for credit losses using information about past events, current conditions and risk characteristics of each customer, and reasonable and supportable forecasts relevant to assessing risk associated with the collectability of receivables and contract assets. See Note 2 to the Consolidated Financial Statements for discussion of credit risk. As of December 31, 2025, the allowance for credit losses totaled $64 million.

The changes in the carrying amount of the allowance for credit losses are as follows (in millions):


Balance at December 31, 2024	$	67
Provision for expected credit losses		71
Recoveries collected		(18	)
Reclass for long-term receivables		(43	)
Write-offs		(10	)
Other		(3	)
Balance at December 31, 2025	$	64

Class of Stock Disclosures [Abstract]

Share Repurchase Program

17. Share Repurchase Program

On April 25, 2024, the Company established a share repurchase program for up to $1 billion of the currently outstanding shares of the Company’s common stock over a period of 36 months. Under the share repurchase program, the Company may repurchase shares from time to time through open market purchases, in privately negotiated transactions or by other means, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Securities Exchange Act of 1934 (the “Exchange Act”), as amended, in accordance with applicable securities laws and other restrictions, including Rule 10b-18. The timing and total amount of any stock repurchases will depend upon business, economic and market conditions, corporate and regulatory requirements, prevailing stock prices and other considerations.

The Company intends to fund the repurchases using its available U.S. cash balances, which may involve the repatriation of foreign earnings not indefinitely reinvested. However, depending on U.S cash balances, the Company may choose to borrow against its revolving credit facility or issue new debt to finance the repurchases. As shares are repurchased, they are constructively retired and returned to an unissued state. During the year ended December 31 2025, the Company repurchased 22.8 million shares of common stock under the program for an aggregate amount of $315 million. During the year ended December 31, 2024, the Company repurchased 14.2 million shares of common stock under the program for an aggregate amount of $229 million.

The difference between the effective tax rate reflected in the provision (benefit) for income taxes and the U.S. federal statutory rate was as follows (in millions) for the year ended December 31, 2025:


	Year Ended December 31, 2025

(1) The state and local jurisdictions that contribute to the majority (greater than 50%) of the tax effect in the category include Texas and Louisiana.

The effective tax rate for the year ended December 31, 2025 was 59.7%, compared to 23.6% for 2024. For 2025, the effective tax rate was negatively impacted by the establishment of additional valuation allowances for foreign tax credit carryforwards and losses in certain jurisdictions with no tax benefit, an unfavorable earnings mix including withholding taxes in higher tax rate jurisdictions, and the impairment of nondeductible goodwill, partially offset by the release of reserves for unrecognized tax benefits.

The difference between the effective tax rate reflected in the provision (benefit) for income taxes and the U.S. federal statutory rate disclosed as follows (in million) for the years ended December 31, 2024 and 2023:


	Year Ended December 31,
	2024			2023
Federal income tax at U.S. statutory rate	$	175		$	129
Foreign income tax rate differential		—			3
Change in deferred tax valuation allowance		(64	)		(564	)

Withholding taxes		47			30
Income tax credits		(6	)		(8	)
Other		30			2
Total income tax provision (benefit)	$	196		$	(373	)

The effective tax rate for the year ended December 31, 2024 was 23.6%, compared to (60.9)% for 2023. For 2024, the effective tax rate was negatively impacted by increased withholding taxes, nondeductible expenses, and losses in certain jurisdictions with no tax benefit, partially offset by a lower rate of U.S. tax on global intangible low-taxed income (GILTI) and the deduction of foreign-derived intangible income (FDII) and the release of valuation allowances in certain jurisdictions as a result of improving forecasted taxable income and availability of net operating losses.

Significant components of our deferred tax assets and liabilities were as follows (in millions):


	December 31,
	2025			2024
Deferred tax assets:
Allowances and operating liabilities	$	246		$	235
Net operating loss carryforwards		138			186

Accrued tax on unremitted earnings		43			41
Other		11			—
Total deferred tax liabilities		222			206
Net deferred tax asset	$	265		$	357

The valuation allowance increased by $86 million during 2025 to $352 million as of December 31, 2025. The valuation allowance primarily related to foreign tax credit carryforwards in the United States and deferred tax assets in certain other jurisdictions due to several factors, including specific jurisdictions in which the Company does not project to generate sufficient future taxable income to realize all or a portion of its deferred tax assets specific to that jurisdiction; the specific nature and timing of future taxable income required to realize certain tax credit carryforwards, most notably U.S. foreign tax credits; and the timing of expiration of certain tax credit carryforwards. This increase in valuation allowance was comprised of $82 million due to the Company’s evaluation of the realizability of deferred tax assets based on future projections of taxable income and $4 million related to foreign currency exchange rate changes.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in millions):


	2025			2024			2023
Unrecognized tax benefit at beginning of year	$	68		$	67		$	62
Gross increase for tax position in current year		6			—			18
Gross increase for tax positions in prior years		30			4			1
Gross decrease for tax positions in prior years		(37	)		—			(3	)
Cash settlements		(4	)		—			(4	)
Lapse of statute of limitations		(7	)		(3	)		(7	)
Unrecognized tax benefit at end of year	$	56		$	68		$	67

Substantially all of the unrecognized tax benefits, if ultimately realized, would be recorded as a reduction to income tax expense in the period realized. To the extent penalties and interest would be assessed on any underpayment of income tax, or interest would be received on tax payments made in connection with tax disputes, such accrued amounts have been classified as a component of income tax expense in the financial statements consistent with the Company’s policy. For the years ended December 31, 2025, 2024 and 2023, we recorded income tax expense (benefit) of $(27) million, $4 million and $5 million, respectively, for interest and penalty related to unrecognized tax benefits. As of December 31, 2025 and 2024, the Company had accrued a receivable (payable) of $7 million and $(24) million, respectively, of interest and penalty relating to unrecognized tax benefits.

The Company is subject to taxation in the United States as well as various states and foreign jurisdictions. The Company has significant operations in the United States, Norway, Saudi Arabia, Brazil, China, the United Kingdom, the Netherlands, Denmark, Canada, and Mexico. Tax years that remain subject to examination by major tax jurisdictions vary by legal entity, but are open in the U.S. for tax years 2017, 2018, and tax years ending after 2021 and outside the U.S. for tax years generally ending after 2018.

Net operating loss carryforwards by jurisdiction and expiration as of December 31, 2025 were as follows (in millions):


	Federal		State		Foreign		Total
2026 - 2030 expiration	$	—	$	6	$	44	$	50
2031 - 2041 expiration		13		118		52		183

Total net operating loss (NOL)	$	63	$	233	$	442	$	738
Tax effected NOL	$	13	$	11	$	114	$	138

The Company has $285 million of excess foreign tax credits in the United States as of December 31, 2025, of which $116 million and $92 million will expire in 2027 and 2028, respectively. The remaining foreign tax credits of $77 million generally expire between 2030 and 2035.

Cash paid (received) for income taxes for the year ended December 31, 2025, is as follows (in millions):

Retirement Benefits [Abstract]

Employee Benefit Plans

10. Employee Benefit Plans

We have benefit plans covering substantially all our employees. Defined-contribution retirement plans cover most of the U.S. and Canadian employees, and benefits are generally based on employee deferrals and matching on those employee contributions. We also have defined contribution plans in Norway and the United Kingdom. For the years ended December 31, 2025, 2024 and 2023, expenses for defined-contribution retirement plans were $90 million, $85 million, and $84 million, respectively, and all funding is current.

The Company offers a benefit plan providing retiree medical coverage in the United States, and as of December 31, 2025, approximately 8,900 employees are eligible for this coverage. In addition, approximately 600 U.S. retirees and/or spouses participate in plans that provide post-retirement healthcare and/or life insurance benefits.

Liabilities associated with the funded status of the defined benefit pension plans are included in the balances of accrued liabilities and other liabilities in the accompanying Consolidated Balance Sheets.

Defined Benefit Pension Plans

Net periodic benefit cost for our defined benefit pension plans aggregated $4 million, $3 million, and $2 million for the years ended December 31, 2025, 2024 and 2023, respectively.

Assumed long-term rates of return on plan assets, discount rates and rates of compensation increases vary for the different plans according to the local economic conditions. The assumption rates used for benefit obligations are as follows:


	Year Ended December 31,
	2025	2024
Discount rate:
United States plan	4.40% - 4.90%	4.90%
International plans	3.80% - 5.40%	3.40% - 5.40%

Salary increase:
United States plan	N/A	N/A
International plans	2.10% - 2.90%	2.50% - 3.50%

The assumption rates used for net periodic benefit costs are as follows:


	Year Ended December 31,
	2025	2024	2023
Discount rate:
United States plan	4.90%	5.50% - 5.60%	4.74% - 5.20%
International plans	3.40%-5.40%	3.20% - 4.50%	3.30% - 4.80%
Salary increase:
United States plan	N/A	N/A	N/A
International plans	2.50%-3.50%	2.50% - 3.75%	2.50% - 3.75%
Expected return on assets:
United States plan	N/A	N/A	4.74%
International plans	3.20%-5.10%	3.20% - 5.40%	3.20% - 4.90%

In determining the overall expected long-term rate of return for plan assets, the Company takes into consideration the historical experience as well as future expectations of the asset mix involved. As different investments yield different returns, each asset category is reviewed individually and then weighted for significance in relation to the total portfolio.

The majority of our plans have projected benefit obligations in excess of plan assets.

The Company expects to pay future benefit amounts on its pension plans of approximately $12 million for each of the next five years and aggregate payments of $126 million.

Plan Assets

The Company and its investment advisers collaboratively reviewed market opportunities using historic and statistical data, as well as the actuarial valuation reports for the plans, to ensure that the levels of acceptable return and risk are well-defined and monitored. Currently, the Company’s management believes that there are no significant concentrations of risk associated with plan assets. Our pension investment strategy worldwide prohibits a direct investment in our own stock.

The following table sets forth by level, within the fair value hierarchy, the plan’s assets carried at fair value (in millions):


	Fair Value Measurements
	Total		Level 1		Level 2		Level 3
December 31, 2024:
Equity securities	$	—	$	—	$	—	$	—
Bonds		90		—		90		—
Other (insurance contracts)		83		—		20		63
Total fair value measurements	$	173	$	—	$	110	$	63
December 31, 2025:
Equity securities	$	—	$	—	$	—	$	—
Bonds		74		—		74		—
Other (insurance contracts)		89		—		5		84
Total fair value measurements	$	163	$	—	$	79	$	84

Level 3 inputs are unobservable (i.e., supported by little or no market activity). Level 3 inputs include management’s own judgment about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk). The return on assets for Level 3 plan assets are immaterial for all periods presented.

Commitments and Contingencies

12. Commitments and Contingencies

The Company operates globally, with operations in 57 countries, and is therefore subject to variety of laws and regulations in multiple jurisdictions. As a result, the Company may be involved in various legal or governmental proceedings, claims or investigations, including personal injury, property damage, environmental, intellectual property, commercial, tax, compliance, trade regulation and other matters arising in the ordinary course of business. There is inherent risk in such matters, and no assurance can be given as to the outcome of these proceedings. Except as discussed herein, the resolution of pending litigation and/or governmental proceedings, in the opinion of management, will not have a material adverse effect on our consolidated results of operations or consolidated financial position.

The Company is subject to customs and trade regulation laws and regulations, including tariffs, in the countries in which we do business and countries to and from which, we import and/or export goods. Such trade regulations can be complex and conflicting, as different countries use customs and trade laws and regulations to promote conflicting policy objectives. Compliance with these laws and regulations presents challenges which could result in material tariffs and liabilities (for example, alleged violation of those laws or when laws conflict between countries).

The Company is currently pursuing litigation against several companies involving royalties due under licenses for technology related to drill bits. This technology resulted in a portfolio of patents related to leaching technology, a revolutionary technology owned by the Company that improves the performance of drill bits and other products utilizing certain synthetic diamond parts. The Company previously sued several drill bit manufacturers for patent infringement and those lawsuits were resolved by a series of licensing agreements with various drill bit manufacturers (the “License Agreements”). To settle and end litigation or to avoid litigation, the licensees were provided access to the portfolio of leaching patents owned by the Company in exchange for a royalty payment, as defined in each License Agreement. The companies agreed to pay the royalties for the right to use the portfolio of patents, whether they used some, all or none of the specific patented claims in any particular patent. The License Agreements provide that they terminate on the date of the last to expire of the patents in the licensed portfolio. Having obtained the benefit of these licenses for more than a decade, all of the drill bit manufacturer licensees unilaterally stopped making royalty payments even though all of the patents in the portfolio have not expired. These companies have asserted, among other reasons, that they are entitled to stop making these payments because they claim to not manufacture products covered by the unexpired patents. Some of these companies stopped making payments after the expiration of what are allegedly the patents in the portfolio that they elected to use. Others paid for some period of time after that date but have since stopped making payments. The Company has sued asserting that failure to pay the royalties is a breach of the License Agreements. The Company is in litigation with most of the licensees seeking a judicial determination that it is entitled to be paid royalties pursuant to the terms of the License Agreements. The licensees have responded with a number of alleged defenses and requests for declaratory judgment all focused on avoiding the payments called for under the License Agreements. The parties’ legal filings to date can be found in the following cases: Grant Prideco, Inc., et al. v. Schlumberger Technology Corp., et al., No. 4:23-cv-00730; Halliburton Energy Services, Inc. v. Grant Prideco, Inc., et al., No. 4:23-cv-01789; and Grant Prideco, Inc., et al. v. Baker Hughes Oilfield Operations Inc., et al., No. 4:25-cv-03459, all in the United States District Court for the Southern District of Texas. We have also recently initiated litigation against Taurex Drill Bits. The legal filings to date can be found in the case Grant Prideco, Inc., et al. v. Taurex Drill Bits, L.L.C., No. 25-BC11B-0065, in the Eleventh Business Court Division for Harris County, Texas. On September 29, 2025, and October 7, 2025, in the lawsuits against Halliburton, Ulterra and Varel, the district court issued rulings, the effect of which is that NOV cannot collect royalties under the License Agreements after the date each licensee stopped making royalty payments. NOV believes the court’s ruling is incorrect and has filed a Notice of Appeal. The Company continues to strongly believe that the royalties for which it has sued are due and owing pursuant to the terms of the License Agreements. Of course, there is inherent risk with the related litigation and the Company makes no assurances as to the outcome of such litigation. See Note 14 to the Consolidated Financial Statements for discussion of the financial impact of royalties.

Geopolitical events continue to pose supply chain and other business risks. The Company’s ability to manufacture equipment and perform services could be impaired by such disruptions and the Company could be exposed to liabilities resulting from additional interruption or delay in its ability to perform due to factors such as war, materials shortages, inflationary pressures, limited manpower, tariffs or otherwise. We may face loss of workers, labor shortages, litigation, fines and/or other adverse consequences resulting from ongoing labor impacts. The combined impact of supply chain and labor market disruptions along with continuing inflationary impacts, as well as monetary and regulatory policies could have material adverse impacts on our financial results.

Disputes may arise from a variety of causes, including weather impacts, cyber, geopolitical, regulatory or other business risks, sometimes these risks may trigger application of force majeure and other contract provisions concerning allocation of responsibility among customers, the Company, and suppliers, resulting in material added cost and/or litigation. Our customers may attempt to cancel or delay projects, cancel contracts, or may invoke force majeure clauses. Our customers may also seek to delay or may default on their payments to us. As a result, the Company may be exposed to additional costs, liabilities and risks which could materially adversely impact our financial performance and results. These potential operational and service delays could result in contractual or other legal claims from our customers. At this time, it is not possible to quantify all these risks, but the combination of these factors could have a material impact on our financial results.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

3. Derivative Financial Instruments

The Company uses derivative financial instruments to manage its foreign currency exchange rate risk. Forward currency contracts are executed to manage the foreign currency exchange rate risk on forecasted revenues and expenses denominated in currencies other than the functional currency of the operating unit (cash flow hedge). The Company also executes forward currency contracts to manage the foreign currency exchange rate risk on recognized nonfunctional currency monetary accounts (non-designated hedge).

At December 31, 2025, the Company has determined the fair value of its derivative financial instruments representing assets of $5 million and liabilities of $4 million (currency related derivatives) using level 2 inputs (inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or indirectly for substantially the full term of the asset or liability) in the fair value hierarchy as the fair value is based on publicly available foreign exchange and interest rates at each financial reporting date. At December 31, 2025, the net fair value of the Company’s foreign currency forward contracts totaled a net asset of $1 million.

Forward currency contracts consist of (in millions):

Cash Flow Hedging Strategy

To protect against the volatility of forecasted foreign currency cash flows resulting from forecasted revenues and expenses, the Company maintains a cash flow hedging program. For derivative instruments that are designated and qualify as a cash flow hedge, the gain or loss on the derivative instrument is recorded in accumulated other comprehensive loss and reclassified into earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings (e.g., in “revenues” when the hedged transactions are cash flows associated with forecasted revenues). The Company includes time value in hedge relationships.

The Company expects accumulated other comprehensive gain of $2 million will be reclassified into earnings within the next twelve months.

Non-designated Hedging Strategy

The Company enters into forward exchange contracts to hedge certain nonfunctional currency monetary accounts. The gain or loss on the derivative instrument is recognized in earnings in other income (expense), together with the changes in the hedged nonfunctional monetary accounts.

The amount of gain (loss) recognized in Other expenses, net was $1 million, $23 million and $(10) million for the years ended 2025, 2024 and 2023, respectively.

The Company has the following fair values of its derivative instruments and their balance sheet classifications (in millions):


	Asset Derivatives					Liability Derivatives
	Balance Sheet	December 31,				Balance Sheet	December 31,
	Location	2025		2024		Location	2025		2024

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	ITEM 1C. CYBERSECURITY As part of the Company’s enterprise risk management, we maintain a cyber risk program with established policies and procedures to detect, prevent, mitigate, and remediate cybersecurity incidents and related risks. The program is led by our Chief Information Security Officer (“CISO”), who has 30 years of experience in information security and is a Certified Information Systems Security Professional. Our CISO reports directly to our Chief Information Officer of Corporate IT, who has over 25 years of experience in all areas of information technology. Our cybersecurity team is comprised of experienced, educated, and certified professionals with decades of experience in cybersecurity leadership roles. Our cyber risk management program is based on recognized industry practices and standards in cybersecurity and information technology. These standards include the National Institute of Standards and Technology (“NIST”) Cybersecurity Framework (“CSF”) and the International Organization for Standardization (“ISO”) 27001. Security controls are managed using an information security management system (“ISMS”), providing a systematic approach consisting of people, processes, and technology. NOV’s ISMS aims to minimize risk and ensure business continuity by proactively limiting the impact of security incidents. Our cybersecurity incident response plan includes an escalation process to senior management, who evaluates various factors related to the cybersecurity incident to assess the impact on the Company and any required disclosures. If a cybersecurity incident was determined to be material by senior management, our Board of Directors would be promptly notified and the incident reported based on applicable legal requirements. Our processes also address cybersecurity risks associated with third-party service providers, including those in our supply chain or who have access to our data or systems. We evaluate third-party service providers from a cybersecurity risk perspective, which may include an assessment of that service provider’s cybersecurity posture or a recommendation of specific mitigation controls. We conduct continuous vulnerability assessments and continuous penetration testing. Additionally, we undergo internal and external assessments of our processes to identify opportunities for improvement and reduce exposure to cybersecurity incidents. The Company’s Board of Directors provides oversight of the Company’s cybersecurity program through periodic updates, typically on a quarterly basis. Additionally, on an annual basis, cybersecurity risks are discussed as part of enterprise risk management. We have not experienced any cybersecurity incidents that have had a material adverse effect on our business, financial condition, results of operations, or cash flows. Although we have not experienced any cybersecurity incidents that are individually, or in aggregate, material, we have experienced cyberattacks in the past, which we believe have thus far been mitigated by preventative, detective, and responsive measures put in place by the Company. We recognize the potential impact of cybersecurity risks on our business strategy, results of operations, and financial condition and take proactive measures to mitigate these risks. See Item 1A. “Risk Factors.”

Description of performance goal							85% with a TSR (total shareholder return) goal and 15% with an internal NVA (“NOV Value Added”, a return on capital metric) goal. TSR performance is determined by comparing the Company’s TSR with the TSR of the members of the Philadelphia Stock Exchange’s Oil Services Sector Index (OSX) for the three-year performance period. The TSR portion of the performance share awards is subject to a vesting cap equal to 100% of Target Level if the Company’s absolute TSR is negative, regardless of relative TSR results. Conversely, if the Company’s absolute TSR is greater than 15% annualized over the three-year performance period the payout amount shall not be less than 50% of Target Level, regardless of relative TSR results. The NVA goal is based on the Company’s improvement in NVA from the beginning of the performance period until the end of the performance period. NVA is calculated as an amount equal to the Company’s (a) gross cash earnings less (b) average gross operating assets times an amount equal to a required return on assets, with certain adjustments.On April 28, 2025, the Company granted 1,839 restricted stock units with a fair value of $12.24 per share. The awards were granted to employees and vest in three equal annual installments commencing on the first anniversary of grant date.

The Company has a five-year unsecured revolving credit facility with a borrowing capacity of $1.5 billion, which matures on September 12, 2029. The Company has the right to increase the aggregate commitments under this agreement to an aggregate amount of up to $2.5 billion upon the consent of only those lenders holding any such increase. Interest under the multicurrency facility is based upon Secured Overnight Financing Rate (SOFR), Euro Interbank Offered Rate (EURIBOR), Sterling Overnight Index Average (SONIA), Canadian Overnight Repo Rate Average (CORRA), or Norwegian Interbank Offered Rate (NIBOR), plus 1.25%, subject to a ratings-based grid or the U.S. prime rate. The credit facility contains a financial covenant establishing a maximum debt-to-capitalization ratio of 60%. As of December 31, 2025, the Company was in compliance with this covenant, with a debt-to-capitalization ratio of 23.8%, and had no outstanding borrowings or letters of credit issued under the facility, resulting in $1.5 billion of available funds.

A consolidated joint venture of the Company borrowed $120 million against a $150 million bank line of credit, payable by June 2032, for the construction of a facility in Saudi Arabia. Interest under the bank line of credit is based upon SOFR plus 1.40%. The bank line of credit contains a financial covenant regarding maximum debt-to-equity ratio of 75%. As of December 31, 2025, the joint venture was in compliance and will not have future borrowings on the line of credit. As of December 31, 2025, the Company has a carrying value of $84 million in borrowings related to this line of credit. The carrying value of debt under the Company’s consolidated joint venture approximates fair value because the interest rates are variable and reflective of current market rates. The Company has $11 million in payments related to this line of credit due in the next twelve months. The Company can repay the entire outstanding facility balance without penalty at its sole discretion.

Other debt at December 31, 2025 included $46 million of amounts owed to current and former minority interest partners of NOV consolidated joint ventures, of which $19 million is due in the next twelve months.

The Company had $946 million of outstanding letters of credit at December 31, 2025, primarily in the U.S. and Norway, that are under various bilateral letter of credit facilities. Letters of credit are issued as bid bonds, advanced payment bonds and performance bonds.

At December 31, 2025 and 2024, the fair value of the Company’s unsecured Senior Notes approximated $1,353 million and $1,285 million, respectively. The fair value of the Company’s debt is estimated using Level 2 inputs in the fair value hierarchy and is based on quoted prices for those of similar instruments. At December 31, 2025 and 2024, the carrying value of the Company’s unsecured Senior Notes approximated $1,589 million and $1,587 million, respectively.

Leases [Abstract]

Leases

8. Leases

The Company leases certain facilities and equipment to support its operations around the world. These leases generally require the Company to pay maintenance, insurance, taxes and other operating costs in addition to rent. Renewal options are common in longer term leases; however, it is rare that the Company intends to exercise a lease option at inception due to the cyclical nature of the Company’s business. Residual value guarantees are not typically part of the Company’s leases. Occasionally, the Company sub-leases excess facility space, generally at terms similar to the source lease. The Company reviews new agreements to determine if they include a lease and, when they do, uses its incremental borrowing rate to determine the present value of the future lease payments as most do not include implicit interest rates.
