NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. DESCRIPTION OF BUSINESS

Huntington Ingalls Industries, Inc. ("HII" or the "Company") is a global, all-domain defense partner, building and delivering the world’s most powerful, survivable naval ships and technologies that safeguard America’s seas, sky, land, space, and cyber. HII is organized into three reportable segments: Ingalls Shipbuilding ("Ingalls"), Newport News Shipbuilding ("Newport News"), and Mission Technologies. For more than a century, the Company's Ingalls segment in Mississippi and Newport News segment in Virginia have built more ships in more ship classes than any other U.S. naval shipbuilder, making HII America's largest shipbuilder. The Mission Technologies segment develops integrated technology solutions and products that enable today's connected, all-domain force.

2. BASIS OF PRESENTATION

Principles of Consolidation - The unaudited condensed consolidated financial statements of HII and its subsidiaries have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and the instructions to Form 10-Q promulgated by the Securities and Exchange Commission ("SEC"). As used in the Notes to the Condensed Consolidated Financial Statements (Unaudited), the terms "HII" and "the Company" refer to HII and its subsidiaries. All intercompany transactions and balances are eliminated in consolidation. For classification of current assets and liabilities related to its long-term production contracts, the Company uses the duration of these contracts as its operating cycle, which is generally longer than one year. Additionally, certain prior year amounts have been reclassified to conform to the current year presentation.

These unaudited condensed consolidated financial statements include all adjustments of a normal recurring nature considered necessary by management for a fair presentation of the unaudited condensed consolidated financial position, results of operations, and cash flows and should be read in conjunction with the Company's audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025 (the "2025 Annual Report on Form 10-K").

The quarterly information is labeled using a calendar convention; that is, first quarter is consistently labeled as ending on March 31, second quarter as ending on June 30, and third quarter as ending on September 30. It is management's long-standing practice to establish interim closing dates using a "fiscal" calendar, which requires the businesses to close their books on a Friday near these quarter-end dates in order to normalize the potentially disruptive effects of quarterly closings on business processes. This practice only exists for interim periods within a reporting year.

Accounting Estimates - The preparation of the Company's unaudited condensed consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Estimates have been prepared on the basis of the most current and best available information, and actual results could differ materially from those estimates.

Fair Value of Financial Instruments - Except for the Company's long-term debt, the carrying amounts of the Company's financial instruments that are recorded at historical cost approximate fair value due to the short-term nature of the instruments and low credit risk associated with the respective counterparties.

The Company maintains multiple grantor trusts to fund certain non-qualified pension plans. These trusts were valued at $244 million and $249 million as of March 31, 2026, and December 31, 2025, respectively, and are presented within miscellaneous other assets on the unaudited condensed consolidated statements of financial position. These trusts consist primarily of investments in marketable securities, which are held at fair value within Level 1 of the fair value hierarchy.

The estimated fair values of the Company's total long-term debt as of March 31, 2026 and December 31, 2025 were $2,688 million and $2,730 million, respectively. The fair values of the Company's long-term debt were calculated based on recent trades of the Company's debt instruments in inactive markets, which fall within Level 2 of the fair value hierarchy.

3. ACCOUNTING STANDARDS UPDATES

Recently Adopted Guidance

There were no new Accounting Standards Updates (“ASU”) adopted during the three months ended March 31, 2026 that had a material impact on the Company’s consolidated financial statements.

Accounting Guidance Issued But Not Adopted as of March 31, 2026

In November 2024, the Financial Accounting Standards Board ("FASB") issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The new guidance requires, among other things, tabular and qualitative disclosure of disaggregated expense information that is included in certain expense line items presented on the consolidated statement of operations. The new guidance also requires that the total amount and definition of selling expenses be disclosed. The new guidance is effective on a prospective basis for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption and retrospective application permitted. The Company is currently evaluating the impacts of the new guidance on its consolidated financial statements.

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. Among other targeted improvements, the new guidance amends existing software cost capitalization guidance by removing all references to software project development stages and providing criteria that clarify the threshold for software cost capitalization to begin. The new guidance is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. The new guidance may be applied on a prospective basis, retrospective basis, or modified basis for in-process projects. The Company is currently evaluating the impacts of the new guidance on its consolidated financial statements.

In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities. The new standard establishes authoritative guidance for the recognition, measurement, and presentation of a grant received by a business entity from a government, including guidance for a grant related to an asset and a grant related to income. The new guidance also amends certain existing disclosure requirements for government assistance provided to business entities. The new guidance is effective for annual reporting periods beginning after December 15, 2028, and interim reporting periods within those annual reporting periods, with early adoption permitted. The new guidance may be applied on a modified prospective basis, modified retrospective basis, or full retrospective basis. The Company is currently evaluating the impacts of the new guidance on its consolidated financial statements.

Other accounting pronouncements issued but not effective until after December 31, 2026, are not expected to have a material impact on the Company's consolidated financial position, results of operations, or cash flows.

4. STOCKHOLDERS' EQUITY

Treasury Stock - In January 2024, the Company's board of directors authorized an increase in the Company's stock repurchase program from $3.2 billion to $3.8 billion and an extension of the term of the program to December 31, 2028. Repurchases are made from time to time at management's discretion in accordance with applicable federal securities laws. For each of the three months ended March 31, 2026 and 2025, the Company did not repurchase any shares. The cost of purchased shares is recorded as treasury stock in the unaudited condensed consolidated statements of financial position.

Dividends - The Company paid cash dividends totaling $54 million and $53 million for the three months ended March 31, 2026 and 2025, respectively.

Accumulated Other Comprehensive Loss - Other comprehensive income (loss) refers to gains and losses recorded as an element of stockholders' equity but excluded from net earnings. The accumulated other comprehensive loss was comprised of unamortized benefit plan costs of $52 million and $53 million as of March 31, 2026, and December 31, 2025, respectively.

Table of Contents

The changes in accumulated other comprehensive loss by component for the three months ended March 31, 2026 and 2025, were as follows:


($ in millions)	Benefit Plans		Total

As of March 31, 2026, the Company had $54.0 billion of remaining performance obligations. The Company expects to recognize approximately 40% of its remaining performance obligations as revenue through 2027, an additional 35% through 2029, and the balance thereafter.

Cumulative Catch-up Revenue Adjustments

The following table presents the effect of net cumulative catch-up revenue adjustments on operating income and diluted earnings per share:


	Three Months Ended March 31
($ in millions, except per share amounts)	2026		2025
Effect on operating income(1)	$	1	$	—
Effect on diluted earnings per share (net of tax)	$	0.02	$	—

(1) For the three months ended March 31, 2026, the effect of net cumulative catch-up revenue adjustments on

operating income is materially consistent with the effect on revenue.

For the three months ended March 31, 2026, no individual favorable or unfavorable cumulative catch-up revenue adjustment was material to the Company's unaudited condensed consolidated statements of operations and comprehensive income.

For the three months ended March 31, 2025, cumulative catch-up revenue adjustments netted to zero, and did not have an effect on operating income or diluted earnings per share. The Company's Newport News segment experienced performance challenges in the construction of aircraft carriers and Virginia class (SSN 774) submarines. For the three months ended March 31, 2025, cumulative catch-up revenue adjustments included significant unfavorable performance adjustments on the Enterprise (CVN 80) and Doris Miller (CVN 81) construction contract and the Virginia class (SSN 774) submarine program, which were offset by contract incentives.

Contract Balances

The Company reports contract balances in a net contract asset or contract liability position on a contract-by-contract basis at the end of each reporting period. Net contract assets were comprised as follows:


($ in millions)	March 31, 2026		December 31, 2025
Contract assets	$	1,989	$	1,758
Contract liabilities	822		1,220
Net contract assets	$	1,167	$	538

Table of Contents

The Company’s net contract assets increased $629 million from December 31, 2025 to March 31, 2026, primarily as a result of the timing of billings across programs on certain U.S. Navy contracts. The Company recognized revenue related to its prior year-end contract liabilities of $758 million and $552 million for the three months ended March 31, 2026 and 2025, respectively.

8. INCOME TAXES

The Company's earnings are primarily domestic, and its effective income tax rates on earnings from operations for the three months ended March 31, 2026 and 2025, were 20.7% and 20.3%, respectively.

For the three months ended March 31, 2026, the Company’s effective tax rate did not differ materially from the federal statutory corporate income tax rate of 21%.

The Company's unrecognized tax benefits increased by $3 million during the three months ended March 31, 2026. As of March 31, 2026, the estimated amounts of the Company's unrecognized tax benefits, excluding interest and penalties, were liabilities of $108 million. Assuming a sustainment of these tax positions, a reversal of $85 million of the accrued amounts would favorably affect the Company's effective federal income tax rate in future periods.

The Company recognizes interest and penalties related to unrecognized tax benefits as income tax expense. For the three months ended March 31, 2026, interest and penalties resulting from the unrecognized tax benefits noted above increased income tax expense by $2 million.

Non-current state income taxes include deferred state income taxes, which reflect the change in deferred state tax assets and liabilities and the tax expense or benefit associated with changes in state unrecognized tax benefits in the relevant period. These amounts are recorded within operating income. Current period state income tax expense is charged to contract costs and included in cost of sales and service revenues in segment operating income.

Internal Revenue Service ("IRS") Audits - The Company reached an agreement in principle with the IRS on the research and development tax credits for the 2016-2021 tax years in 2025. This resolution was submitted to the Joint Committee on Taxation for approval in March 2026. Also, in the first quarter of 2026, the IRS initiated an audit of the research and development tax credits claimed on the Company's filed returns for the 2022-2023 tax years. The Company believes that its unrecognized tax benefits are adequate and will cover the expected impact of the agreement with the IRS and any adjustments resulting from the IRS audit of the 2022-2023 research and development tax credits.

9. INVESTIGATIONS, CLAIMS, AND LITIGATION

The Company is involved in legal proceedings before various courts and administrative agencies, and is periodically subject to government examinations, inquiries and investigations. The Company accrues for losses associated with legal proceedings when, and to the extent that, loss amounts related to the legal proceedings are probable and can be reasonably estimated. The actual losses that might be incurred to resolve such legal proceedings may be higher or lower than the amounts accrued. The Company also provides footnote disclosure for matters for which a material loss is reasonably possible but a reserve has not been accrued because the likelihood of a material loss is not probable.

Antitrust Complaint - In October 2023, a class action antitrust lawsuit was filed against the Company and other defendants in the U.S. District Court for the Eastern District of Virginia. The lawsuit names several HII companies, among other companies, as defendants. The named plaintiffs generally allege that the defendant companies have

Table of Contents

adhered to a “gentlemen’s agreement” that prohibits any defendant from actively recruiting naval engineers from other defendants. The complaint seeks class certification, treble damages, and any other relief to which the plaintiffs are entitled. The District Court dismissed the lawsuit against all defendants in April 2024 on statute of limitations grounds without addressing the motions to dismiss filed by the defendants on other grounds. The Fourth Circuit Court of Appeals reversed the dismissal and remanded the case to the District Court for further proceedings. In November 2025, the District Court denied the defendants' remaining motions to dismiss the lawsuit. In March 2026, the Company reached agreement with the plaintiffs to resolve their claims. The Company has recorded a liability related to the agreement that is not material to the Company's consolidated financial position, results of operations, or cash flows.

Insurance Claim - In September 2020, the Company filed a complaint against 32 reinsurers in the Superior Court, State of Vermont, Franklin Unit, seeking a judgment declaring that the Company's business interruption and other losses associated with COVID-19 are covered by the Company's property insurance program. The Company also initiated arbitration proceedings against six other reinsurers seeking similar relief. In July 2021, the Vermont court granted the reinsurers’ motion for judgment on the pleadings, which would have ended the Company’s claim. The Company appealed the decision to the Vermont Supreme Court, which reversed and remanded the lower court’s decision in September 2022, allowing the Company’s claim to proceed. In 2025, the parties filed dispositive motions and await the court’s decision. The Company cannot at this time predict the outcome of this matter.

U.S. Government Investigations and Claims - Departments and agencies of the U.S. Government have the authority to investigate various transactions and operations of the Company, and the results of such investigations may lead to administrative, civil, or criminal proceedings, the ultimate outcome of which could be fines, penalties, repayments or compensatory, treble, or other damages. U.S. Government regulations provide that certain findings against a contractor may also lead to suspension or debarment from future U.S. Government contracts or the loss of export privileges. Any suspension or debarment would have a material effect on the Company because of its reliance on government contracts.

In 2024, the Company identified certain quality issues involving noncompliance with welding procedures at Newport News. The Company commenced an investigation and disclosed the matter to the U.S. Government. The Company continues to work with its U.S. Navy customer to evaluate the full extent of the matter and cannot at this time predict or reasonably estimate the ultimate outcome of this matter.

Asbestos Related Claims - HII and its predecessors-in-interest are defendants in a longstanding series of cases that have been and continue to be filed in various jurisdictions around the country, wherein former and current employees and various third parties allege exposure to asbestos containing materials while on or associated with HII premises or while working on vessels constructed or repaired by HII. In some instances, partial or full insurance coverage is available for the Company's liabilities. The costs to resolve cases during the three months ended March 31, 2026 and 2025, were not material individually or in the aggregate. The Company’s estimate of asbestos-related liabilities is subject to uncertainty because such liabilities are influenced by many variables that are inherently difficult to predict. Although the Company believes the ultimate resolution of current cases will not have a material effect on its condensed consolidated financial position, results of operations, or cash flows, it cannot predict what new or revised claims or litigation might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome of asbestos related litigation.

Other - The Company is party to various other claims, arbitrations, investigations, and other legal proceedings that arise in the ordinary course of business, including U.S. Government investigations and claims that could result in administrative, civil, or criminal proceedings involving the Company. The Company is a contractor with the U.S. Government, and such proceedings can therefore include False Claims Act allegations against the Company. Based on the information available to the Company to date, the Company believes that the resolution of these other claims, legal proceedings, and investigations will not have a material effect on its condensed consolidated financial position, results of operations, or cash flows. However, the Company cannot predict what new or revised claims, litigation, or other proceedings might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome of these matters.

10. COMMITMENTS AND CONTINGENCIES

Contract Performance Contingencies - Contract profit margins may include estimates of revenues for matters on which the customer and the Company have not reached agreement, such as settlements in the process of negotiation, contract changes, claims, and requests for equitable adjustment for unanticipated contract costs. These

Table of Contents

estimates are based upon management's best assessment of the underlying causal events and circumstances and recognized to the extent of expected recovery based upon contractual entitlements and the probability of successful negotiation with the customer. The Company believes its outstanding customer settlements will be resolved without material impact to its financial position, results of operations, or cash flows.

Environmental Matters - The estimated costs to complete environmental remediation are accrued when it is probable that the Company will incur such costs in the future to address environmental conditions at currently or formerly owned or leased operating facilities, or at sites where it has been named a Potentially Responsible Party by the Environmental Protection Agency or similarly designated by another environmental agency, and the related costs can be reasonably estimated by management. When only a range of costs is established and no amount within the range is more probable than another, the minimum amount in the range is accrued. Environmental liabilities are recorded on an undiscounted basis and are expensed or capitalized as appropriate. Capitalized expenditures, if any, relate to long-lived improvements in currently operating facilities. The Company does not record insurance recoveries before collection is probable. As of March 31, 2026 and December 31, 2025, the Company did not have any accrued receivables related to insurance reimbursements or recoveries for environmental matters.

The Company’s environmental liability accruals do not include any litigation costs related to environmental matters, nor do they include amounts recorded as asset retirement obligations. Management estimates that as of March 31, 2026, the probable estimable future cost for environmental remediation is not material. Although management cannot predict whether new information gained as remediation progresses or the Company incurs additional remediation obligations will materially affect the estimated liability accrued, management does not believe that future remediation expenditures will have a material effect on the Company's consolidated financial position, results of operations, or cash flows.

Financial Arrangements - In the ordinary course of business, HII uses letters of credit issued by commercial banks to support certain leases, insurance policies, and contractual performance obligations, as well as surety bonds issued by insurance companies principally to support the Company's self-insured workers' compensation plans. As of March 31, 2026, the Company had $11 million in issued but undrawn letters of credit and $368 million of surety bonds outstanding.

U.S. Government Claims - From time to time, the U.S. Government communicates to the Company potential claims, disallowed costs, and penalties concerning prior costs incurred by the Company with which the U.S. Government disagrees. When such preliminary findings are presented, the Company and U.S. Government representatives engage in discussions, from which the Company evaluates the merits of the claims and assesses the amounts being questioned. Although the Company believes that the resolution of any of these matters will not have a material effect on its consolidated financial position, results of operations, or cash flows, it cannot predict the ultimate outcome of these matters.

Collective Bargaining Agreements - Of the Company's approximately 44,000 employees, 45% are covered by a total of 13 collective bargaining agreements. Newport News has three collective bargaining agreements covering represented employees, which expire in February 2030, December 2030 and April 2031. Ingalls has five collective bargaining agreements covering represented employees, all of which expire in March 2031. Mission Technologies has a total of 80 employees covered by five collective bargaining agreements, which expire in September 2026, December 2027, September 2028, and two that expire in August 2027.

Collective bargaining agreements generally expire after three to five years and are subject to renegotiation at that time. The Company believes its relationship with its employees is satisfactory.

Purchase Obligations - Periodically the Company enters into agreements to purchase goods or services that are enforceable and legally binding on the Company and specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum, or variable price provisions; and the approximate timing of the transaction. These obligations are primarily comprised of open purchase order commitments to vendors and subcontractors pertaining to funded contracts.

12. STOCK COMPENSATION PLANS

During the three months ended March 31, 2026 and 2025, the Company issued new stock awards as follows:

Restricted Performance Stock Rights - For the three months ended March 31, 2026, the Company granted approximately 0.1 million RPSRs at a weighted average share price of $435.58. These rights are subject to cliff vesting on December 31, 2028. For the three months ended March 31, 2025, the Company granted approximately 0.2 million RPSRs at a weighted average share price of $168.81. These rights are subject to cliff vesting on December 31, 2027. All of the RPSRs are subject to the achievement of performance-based targets at the end of the respective vesting periods and will ultimately vest between 0% and 200% of grant date value.

Compensation Restricted Stock Rights - For the three months ended March 31, 2026, the Company granted approximately 0.1 million compensation RSRs at a weighted average share price of $435.58. For the three months ended March 31, 2025, the Company granted approximately 0.1 million compensation RSRs at a weighted average share price of $168.81. These rights vest 33 1/3% upon each of the first, second, and third anniversaries of the grant date.

Retention Restricted Stock Rights - Retention stock awards are granted to key employees primarily to incentivize continued employment with the Company. For the three months ended March 31, 2026, the Company did not grant any retention stock awards. For the three months ended March 31, 2025, the Company granted approximately 1,300 retention RSRs at a weighted average share price of $189.40, with cliff vesting one to two years from the grant date.

Table of Contents

The Company also received transfers of stock awards from employees in satisfaction of tax withholding obligations associated with the vesting of stock awards during the period. Because the stock awards are surrendered in lieu of payments of cash to settle tax obligations and the stock is not issued, the Company does not account for these transfers as treasury stock.

Stock award activity for the three months ended March 31, 2026, and 2025, was as follows:


	Stock Awards (in thousands)	Weighted-Average Grant Date Fair Value		Weighted-Average Remaining Contractual Term (in years)
Outstanding at December 31, 2024	550	$	221.59	1.0 year

Business Environment

Against a backdrop of heightened geopolitical tension and domestic policy realignment, we continue to see uncertainty in the economy, our industry, and our company. Our customers, suppliers, and subcontractors continue to face challenges. We cannot predict how long these challenges will continue, whether these challenges will change over time, or whether our actions to address these challenges will be successful.

Defense Spending Environment – The fiscal year 2026 budget cycle concluded with the passage of the Consolidated Appropriations Act, 2026, signed into law February 3, 2026. The fiscal year 2026 defense appropriations bill includes continued incremental funding for Enterprise (CVN 80) and Doris Miller (CVN 81), along with advance procurement for William J. Clinton (CVN 82); continued funding for the RCOH of USS John C. Stennis (CVN 74); funding for the Virginia class (SSN 774) and Columbia class (SSBN 826) submarine programs; advanced procurement for the Arleigh Burke class (DDG 51) destroyer program, including additional funding for shipyard infrastructure and wage enhancements; and funding for long-lead-time materials for the new FF(X) frigate program. Additionally, the bill provides funding for the Maritime Industrial Base to invest in critical areas including supplier capacity and capability, strategic outsourcing, workforce training, and technology and infrastructure.

On April 3, 2026, the Trump Administration released the President's topline recommendations on funding levels for fiscal year 2027. The proposed budget recommends $60.2 billion in discretionary funding for the shipbuilding construction account and an additional $5.6 billion in mandatory funding, for a total of $65.8 billion for shipbuilding procurement. Included in the discretionary request is funding for one Columbia class (SSBN 826) submarine, two Virginia class (SSN 774) submarines, one Arleigh Burke class (DDG 51) destroyer, one San Antonio class (LPD 17) amphibious transport dock ship, one America class (LHA 6) amphibious assault ship, and the first FF(X) frigate. The fiscal year 2027 budget request continues funding Gerald R. Ford class (CVN 78) aircraft carriers and aircraft carrier refueling programs, and provides initial advance procurement funding for the lead ship of the Trump class (BBG(X)) battleship program. The fiscal year 2027 budget request also reflects increased investments in capability enablers including unmanned surface and underwater vehicles.

Global Geopolitical and Economic Environment – The global geopolitical and economic environment continues to be impacted by uncertainty, heightened geopolitical tensions, and instability. Geopolitical relationships continue to change, and the U.S. and its allies face a global security environment that includes threats from state and non-state actors, including major global powers, as well as terrorist organizations, emerging nuclear tensions, diverse regional security concerns, and political instability. These global threats persist across all domains, from undersea to space to cyber, and the global market for defense products, services, and solutions is driven by these complex and evolving security challenges. In addition, changes in the global economic environment, including changes in international trade policies, including those imposing tariffs, could further impact the global market for defense products. Our current operating environment exists in the broader context of political and socioeconomic priorities and reflects, among other things, the continued impact of and uncertainty surrounding geopolitical tensions, financial market volatility, inflation, trade policy, and a challenging labor market.

Operating Performance Assessment and Reporting

We manage and assess the performance of our business based on our performance on individual contracts and programs using the financial measures referred to below, with consideration given to the Critical Accounting Policies, Estimates, and Judgments referred to in this section. Our portfolio of long-term contracts is largely flexibly-priced. Therefore, sales tend to fluctuate in concert with costs across our large portfolio of active contracts, with operating income being a critical measure of operating performance. Under the Federal Acquisition Regulation rules that govern our business with the U.S. Government, most types of costs are allowable, and we do not focus on individual cost groupings, such as cost of sales or general and administrative expenses, as much as we do on total contract costs, which are a key factor in determining contract operating income. As a result, in evaluating our operating performance, we look primarily at changes in sales and service revenues, as well as operating income, including the effects of significant changes in operating income as a result of changes in contract financial estimates and the use of the cumulative catch-up method of accounting in accordance with GAAP. This approach is consistent with the long-term life cycle of our contracts, as management assesses the bidding of each contract by focusing on net sales and operating profit and monitors performance in a similar manner through contract completion. Consequently, our discussion of business segment performance focuses on net sales and operating profit, consistent with our approach for managing our business.

Sales and Service Revenues

Period-to-period revenues reflect performance under new and ongoing contracts. Changes in sales and service revenues are typically expressed in terms of volume. Unless otherwise described, volume generally refers to increases (or decreases) in reported revenues due to varying production activity levels, delivery rates, or service levels on individual contracts. Volume changes will typically carry a corresponding income change based on the profit margin rate for a particular contract.

Sales and service revenues for the three months ended March 31, 2026, increased $365 million, or 13%, compared to the same period in 2025, primarily due to higher volumes at Newport News, Ingalls, and Mission Technologies.

Net Cumulative Catch-up Revenue Adjustments

For the three months ended March 31, 2026 and 2025, favorable and unfavorable cumulative catch-up revenue adjustments were as follows:


	Three Months Ended March 31
($ in millions)	2026		2025
Gross favorable adjustments	$	66	$	80
Gross unfavorable adjustments	(65)		(80)
Net adjustments	$	1	$	—

See Note 6: Revenue and Segment Operating Results in this section for additional information on our net cumulative catch-up revenue adjustments.

Cost of Product Sales and Service Revenues

Cost of sales for both product sales and service revenues consists of materials, labor, and subcontracting costs, as well as an allocation of indirect costs for overhead. We manage the type and amount of costs at the contract level, which is the basis for estimating our total costs at completion of our contracts. Unusual fluctuations in operating performance driven by changes in a specific cost element across multiple contracts are described in our analysis.

Refer to Segment Operating Results and Product and Service Revenues and Cost Analysis in this section for details related to cost of sales for both product sales and service revenues.

Income from Operating Investments, Net

The activities of our operating investments are closely aligned with the operations of the segments holding the investments. We therefore record income related to earnings from equity method investments in our operating income.

Refer to Segment Operating Results in this section for details related to income from operating investments.

General and Administrative Expenses

In accordance with industry practice and the regulations that govern the cost accounting requirements for government contracts, most general and administrative expenses are considered allowable and allocable costs on government contracts. These costs are allocated to contracts in progress on a systematic basis, and contract performance factors include this cost component as an element of cost.

General and administrative expenses for the three months ended March 31, 2026 increased $12 million from the same period in 2025, primarily due to higher non-current state income taxes and higher overhead costs.

Operating Income

We consider operating income an important measure for evaluating our operating performance, and, consistent with industry practice, we define operating income as revenues less the related costs of producing the revenues and general and administrative expenses.

Segment Operating Income

We internally manage our operations by reference to "segment operating income," which is a non-GAAP measure and is defined as operating income before the Operating FAS/CAS Adjustment and non-current state income taxes, neither of which affects contract performance. Segment operating income is a measure we use to evaluate our core operating performance as it reflects the aggregate performance results of contracts within a segment. When analyzing our operating performance, investors should use segment operating income in addition to, and not as an alternative for, operating income or any other performance measure presented in accordance with GAAP. We believe segment operating income reflects an additional way of viewing aspects of our operations that, when viewed with our GAAP results, provides a more complete understanding of factors and trends affecting our business. We

Table of Contents

believe the measure is used by investors and is a useful indicator to measure our performance. Because not all companies use identical calculations, our presentation of segment operating income may not be comparable to similarly titled measures of other companies.

Changes in segment operating income are typically expressed in terms of volume, as discussed in Sales and Service Revenues above, or performance. Performance refers to changes in contract profit margin rates. These changes typically relate to profit recognition associated with revisions to estimated costs at completion ("EAC"), which reflect improved or deteriorated operating performance on that contract. Operating income changes are accounted for on a cumulative to date basis at the time an EAC change is recorded. Segment operating income may also be affected by, among other things, contract performance, inflationary pressures on our supply chain, the effects of workforce stoppages and other labor-related shortfalls, the availability of raw materials, the effects of natural disasters such as hurricanes, resolution of disputed items with the customer, recovery of insurance proceeds, and other discrete events. At the completion of a long-term contract, any originally estimated costs not incurred or reserves not fully utilized, such as warranty reserves, could also impact contract earnings. Where such items have occurred and the effects are material, a separate description is provided. Refer to Segment Operating Results in this section for activity within each segment.

The following table reconciles operating income to segment operating income:


	Three Months Ended March 31
					2026 vs. 2025
($ in millions)	2026		2025		Dollars		Percent
Operating income	$	155	$	161	$	(6)	(4)	%

Non-current state income taxes	8		—		8		—	%
Segment operating income	$	172	$	171	$	1	1	%

FAS/CAS Adjustment and Operating FAS/CAS Adjustment

The FAS/CAS Adjustment reflects the difference between expenses for pension and other postretirement benefits determined in accordance with GAAP ("FAS") and the expenses for these items included in segment operating income in accordance with U.S. Cost Accounting Standards ("CAS"). The Operating FAS/CAS Adjustment excludes the following components of net periodic benefit costs: interest cost, expected return on plan assets, amortization of prior service cost (credit) and actuarial loss (gain), and settlement and curtailment effects.

The components of the Operating FAS/CAS Adjustment were as follows:


	Three Months Ended March 31

The Operating FAS/CAS Adjustment was a net expense of $9 million and $10 million for the three months ended March 31, 2026 and 2025, respectively. The favorable change in the Operating FAS/CAS Adjustment was primarily driven by higher asset returns in 2025.

Non-current State Income Taxes

Non-current state income taxes include deferred state income taxes, which reflect the change in deferred state tax assets and liabilities, and the tax expense or benefit associated with changes in state unrecognized tax benefits in the relevant period. These amounts are recorded within operating income. Current period state income taxes are charged to contract costs and included in cost of sales and service revenues in segment operating income.

Table of Contents

Non-current state income tax expense was $8 million for the three months ended March 31, 2026, compared to a non-current state income tax expense of less than $1 million for the three months ended March 31, 2025. The unfavorable change in non-current state income taxes was driven by an increase in deferred state income tax expense, primarily attributable to a change in net capitalized research and development expenditures and a change in state unrecognized tax benefits for the prior period.

OTHER FINANCIAL INFORMATION

Interest Expense

Interest expense for the three months ended March 31, 2026, was $22 million, compared with $28 million for the same period in 2025. The decrease in interest expense was driven by a decrease in outstanding long-term debt from the prior period.

Non-Operating Retirement Benefit

The non-operating retirement benefit includes the following components of net periodic benefit costs: interest cost, expected return on plan assets, amortization of prior service cost (credit) and actuarial loss (gain), and settlement and curtailment effects.

For the three months ended March 31, 2026, the non-operating retirement benefit was $53 million, compared with $48 million for the same period in 2025. The favorable change in the non-operating retirement benefit was primarily driven by higher asset returns in 2025.

Other, Net

Other, net income for the three months ended March 31, 2026, was $2 million, compared with other, net income of $6 million for the same period in 2025. The decrease in other, net income was primarily driven by an increase in unrealized losses on investments.

Federal and Foreign Income Taxes

Our effective income tax rates on earnings from operations for the three months ended March 31, 2026 and 2025, were 20.7% and 20.3%, respectively.

For the three months ended March 31, 2026, our effective tax rate did not differ materially from the federal statutory corporate income tax rate of 21%.

In January 2026, the Organization for Economic Co-operation and Development issued administrative guidance on Pillar Two’s 15% global minimum tax, including a “side-by-side" ("SbS") system with permanent and temporary safe harbors. The U.S. is recognized as a qualified SbS regime, which effectively alleviates U.S. based multi-national companies from top-up tax collectible under Pillar Two. We expect that the SbS system or other transitional safe harbor provisions will be broadly applicable to our international operations and, accordingly, do not expect Pillar Two to have a material impact on our effective tax rate, consolidated results of operations, financial position, or cash flows.

BACKLOG

Total backlog as of March 31, 2026, and December 31, 2025, was $54.0 billion and $53.1 billion, respectively. Total backlog includes both funded backlog (firm orders for which funding is contractually obligated by the customer) and unfunded backlog (firm orders for which funding is not currently contractually obligated by the customer). Backlog excludes unexercised contract options and unfunded indefinite delivery/indefinite quantity orders. For contracts having no stated contract values, backlog includes only the amounts committed by the customer as of March 31, 2026 and December 31, 2025, respectively.

The following table presents funded and unfunded backlog by segment as of March 31, 2026, and December 31, 2025:


	March 31, 2026						December 31, 2025
($ in millions)	Funded		Unfunded		Total Backlog		Funded		Unfunded		Total Backlog

Table of Contents

We expect approximately 21% of the $53.1 billion total backlog as of December 31, 2025, to be converted into sales in 2026. U.S. Government orders comprised substantially all of the backlog as of March 31, 2026 and December 31, 2025.

Contract Awards

The value of new contract awards during the three months ended March 31, 2026, was approximately $4.0 billion, primarily driven by awards at Newport News and Ingalls.

LIQUIDITY AND CAPITAL RESOURCES

We seek to efficiently convert operating results into cash for deployment in operating our businesses, implementing our business strategy, and maximizing stockholder value. We use various financial measures to inform our capital deployment strategy, including net cash used in operating activities and free cash flow. We believe these measures are useful to investors in assessing our financial performance.

The following table summarizes key components of cash flow used in operating activities:


	Three Months Ended March 31				2026 vs. 2025

($ in millions)	2026		2025		Dollars
Net earnings	$	149	$	149	$	—
Depreciation and amortization of purchased intangibles	76		79		(3)
Stock-based compensation	21		24		(3)

Deferred income taxes	43		(11)		54




Loss (gain) on investments in marketable securities	3		(3)		6

Other non-cash transactions, net	3		3		—

Trade working capital increase	(640)		(598)		(42)
Net cash used in operating activities	$	(390)	$	(395)	$	5

We have historically maintained a capital structure comprised of a mix of equity and debt financing. We expect to meet our current debt obligations as they come due through internally generated funds from current levels of operations, existing borrowing facilities, and/or through refinancing in the debt markets prior to the maturity dates of our debt.

Cash Flows

Operating Activities

Cash used in operating activities for the three months ended March 31, 2026, was $390 million, compared with cash used in operating activities of $395 million for the same period in 2025.

We expect cash generated from operations in combination with our current cash and cash equivalents, as well as existing borrowing facilities, to be sufficient to service debt and retiree benefit plans, meet contractual obligations, and fund capital expenditures for at least the next twelve calendar months beginning April 1, 2026, and beyond such twelve-month period based on our current business plans.

Investing Activities

Cash used in investing activities for the three months ended March 31, 2026, was $71 million, compared to $199 million used in investing activities for the same period in 2025. The change in investing cash was primarily driven by the acquisition of a business in the first quarter of 2025.

Table of Contents

For 2026, we expect our capital expenditures for maintenance and sustainment to be approximately 1.0% to 1.5% of annual revenues and our discretionary capital expenditures to be approximately 3.0% to 3.5% of annual revenues. Our capital expenditures are expected to increase due to investments to expand our shipbuilding capacity.

Financing Activities

Cash used in financing activities for the three months ended March 31, 2026, was $97 million, compared with $70 million used in financing activities for the same period in 2025. The change in cash used in financing activities was primarily due to an increase in employee taxes on certain share-based payment arrangements.

Free Cash Flow

Free cash flow represents cash used in operating activities less capital expenditures net of related grant proceeds. Free cash flow is not a measure recognized under GAAP. Free cash flow has limitations as an analytical tool and should not be considered in isolation from, or as a substitute for, net earnings as a measure of our performance or net cash used in operating activities as a measure of our liquidity. We believe free cash flow is an important liquidity measure for our investors because it provides them insight into our current and period-to-period performance and our ability to generate cash from continuing operations. We also use free cash flow as a key operating metric in assessing the performance of our business and as a key performance measure in evaluating management performance and determining incentive compensation. Free cash flow may not be comparable to similarly titled measures of other companies.

The following table reconciles net cash used in operating activities to free cash flow:


	Three Months Ended March 31				2026 vs. 2025

($ in millions)	2026		2025		Dollars
Net cash used in operating activities	$	(390)	$	(395)	$	5
Less capital expenditures:
Capital expenditure additions	(74)		(67)		(7)
Grant proceeds for capital expenditures	3		—		3
Free cash flow	$	(461)	$	(462)	$	1

Free cash flow for the three months ended March 31, 2026, increased $1 million from the same period in 2025.

Governmental Regulation and Supervision

The U.S. Government has the ability, pursuant to regulations relating to contractor business systems, to decrease or withhold contract payments if it determines material weaknesses exist in one or more such systems. As of March 31, 2026 and 2025, the cumulative amounts of payments withheld by the U.S. Government under our contracts subject to these regulations were not material to our liquidity or cash flows.

Off-Balance Sheet Arrangements

In the ordinary course of business, we use letters of credit issued by commercial banks to support certain leases, insurance policies, and contractual performance obligations, as well as surety bonds issued by insurance companies principally to support our self-insured workers' compensation plans. As of March 31, 2026, $11 million in letters of credit were issued but undrawn and $368 million of surety bonds were outstanding. As of March 31, 2026, we had no other significant off-balance sheet arrangements.

GLOSSARY OF PROGRAMS

Included below are brief descriptions of some of the programs discussed in this Quarterly Report on Form 10-Q.


Program Name						Program Description

Aircraft carrier RCOH						Perform refueling and complex overhaul ("RCOH") of nuclear-powered aircraft carriers, which is required at the mid-point of their 50-year life cycle. USS John C. Stennis (CVN 74) arrived at Newport News for the start of its RCOH in May 2021, and USS George Washington (CVN 73) was redelivered to the U.S. Navy in May 2023.

America class (LHA 6) amphibious assault ships						Design and build large deck amphibious assault ships that provide forward presence and power projection as an integral part of joint, interagency and multinational maritime expeditionary forces. The America class (LHA 6) ships, together with the Wasp class (LHD 1) ships, are the successors to the decommissioned Tarawa class (LHA 1) ships. The America class (LHA 6) ships optimize aviation operations and support capabilities. In 2023, we were awarded a long-lead-time material contract for Helmand Province (LHA 10), and in 2024, we were awarded a contract modification for the detail design and construction of Helmand Province (LHA 10). We are currently constructing Bougainville (LHA 8) and Fallujah (LHA 9).

Arleigh Burke class (DDG 51) destroyers						Build guided missile destroyers designed for conducting anti-air, anti-submarine, anti-surface, and strike operations. The Aegis-equipped Arleigh Burke class (DDG 51) destroyers are the U.S. Navy's primary surface combatant, and have been constructed in variants, allowing technological advances during construction. We delivered USS Jack H. Lucas (DDG 125) and USS Ted Stevens (DDG 128) in 2023 and 2025, respectively. We have contracts to construct the following Arleigh Burke class (DDG 51) destroyers: Jeremiah Denton (DDG 129), George M. Neal (DDG 131), Sam Nunn (DDG 133), Thad Cochran (DDG 135), John F. Lehman (DDG 137), Telesforo Trinidad (DDG 139), Ernest E. Evans (DDG 141), Charles J. French (DDG 142), Richard J. Danzig (DDG 143), Intrepid (DDG 145), and Robert Kerrey (DDG 146).

Columbia class (SSBN 826) submarines						Design and construct modules for Columbia class (SSBN 826) nuclear ballistic missile submarines ("SSBNs") as a subcontractor to Electric Boat. SSBNs are the most secure and survivable of our nation’s nuclear deterrent triad. Columbia class SSBNs will carry approximately 70 percent of the nation’s nuclear arsenal. The Columbia class (SSBN 826) program plan of record is to construct 12 new SSBNs to replace the current aging Ohio class. As a subcontractor to Electric Boat, we leverage our Virginia class (SSN 774) experience to perform design work and build modules for the entire Columbia class (SSBN 826) submarine program. We have been awarded contracts from Electric Boat for integrated product and process development, providing long–lead–time material and advance construction, and construction of the first two boats of the Columbia class (SSBN 826) submarine program. Construction of the first Columbia class (SSBN 826) submarine began in 2020. In 2023, we received an award modification for long-lead-time material and advance construction for the next five boats.

Gerald R. Ford class (CVN 78) aircraft carriers						Design and construction for the Ford class program, which is the aircraft carrier replacement program for the decommissioned Enterprise (CVN 65) and Nimitz class (CVN 68) aircraft carriers. USS Gerald R. Ford (CVN 78), the first ship of the Ford class, was delivered to the U.S. Navy in the second quarter of 2017. In June 2015, we were awarded a contract for the detail design and construction of John F. Kennedy (CVN 79), following several years of engineering, advance construction, and purchase of long-lead-time components and material. In addition, we have received awards for detail design and construction of Enterprise (CVN 80) and Doris Miller (CVN 81). This category also includes the class' non-recurring engineering. The class is expected to bring improved warfighting capability, quality of life improvements for sailors, and reduced life cycle costs.

Table of Contents


Legend class National Security Cutter						Design and build the U.S. Coast Guard's National Security Cutters ("NSCs"), the largest and most technically advanced class of cutter in the U.S. Coast Guard. The NSC is equipped to carry out maritime homeland security, maritime safety, protection of natural resources, maritime mobility, and national defense missions. There were initially 11 ships for this program, of which the first ten ships have been delivered. In 2025, we reached agreement with the U.S. Coast Guard to terminate production and delivery of the 11th and final ship.

Naval nuclear support services						Provide services to and in support of the U.S. Navy, ranging from services supporting the Navy's carrier and submarine fleets to maintenance services at U.S. Navy training facilities. Naval nuclear support services include design, construction, maintenance, and disposal activities for in-service U.S. Navy nuclear ships worldwide through mobile and in-house capabilities. Services include maintenance services on nuclear reactor prototypes, such as those at the Kenneth A. Kesselring Site, a research and development facility in New York that supports the U.S. Navy, which were completed in 2024.

San Antonio class (LPD 17) amphibious transport dock ships						Design and build amphibious transport dock ships, which are warships that embark, transport, and land elements of a landing force for a variety of expeditionary warfare missions, and also serve as the secondary aviation platform for Amphibious Readiness Groups. The San Antonio class (LPD 17) is the newest addition to the U.S. Navy's 21st century amphibious assault force, and these ships are a key element of the U.S. Navy's seabase transformation. In 2022, we were awarded a long-lead-time material contract for Philadelphia (LPD 32). In 2023, we received an award modification for the detail design and construction of Philadelphia (LPD 32). In 2024, we delivered USS Richard M. McCool Jr. (LPD 29), and we were awarded a multi-ship procurement contract for the construction of Travis Manion (LPD 33), LPD 34 (unnamed), and LPD 35 (unnamed). We are currently constructing Harrisburg (LPD 30), Pittsburgh (LPD 31), and Philadelphia (LPD 32).

Virginia class (SSN 774) fast attack submarines						Construct attack submarines as the principal subcontractor to Electric Boat. The Virginia class (SSN 774) is a post-Cold War design tailored to excel in a wide range of warfighting missions, including anti-submarine and surface ship warfare; special operation forces; strike; intelligence, surveillance, and reconnaissance; carrier and expeditionary strike group support; and mine warfare.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are exposed to certain market risks, including those relating to interest rates and inflation.

Interest Rates - Our floating rate financial instruments subject to interest rate risk include a $1.7 billion revolving credit facility and a $1.7 billion commercial paper program. As of March 31, 2026, we had no indebtedness outstanding under our revolving credit facility or our commercial paper program, and therefore had no interest rate risk with respect to these instruments.

Inflation - Macroeconomic factors have contributed, and we expect will continue to contribute, to increasing cost inflation for raw materials, components, and supplies. We mitigate some cost inflation risk by negotiating long-term agreements with certain raw material suppliers and incorporating price escalation provisions in customer contracts to the extent possible. We include assumptions of anticipated cost growth in the development of our cost of completion estimates, but if inflationary conditions continue over the long-term, our cost assumptions may not be sufficient to cover all cost escalation or may impact the availability of resources to execute the respective contracts. Persistent cost inflation over the long-term may have an adverse impact on our financial position, results of operations, or cash flows.
