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.

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, 2024 (the "2024 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 $ 249 million and $ 233 million as of September 30, 2025, and December 31, 2024, 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 value of the Company's total long-term debt as of September 30, 2025 was $ 2,707 million. There was no current portion of long-term debt and no finance lease liabilities as of September 30, 2025. The estimated fair value of the Company's total long-term debt, including the current portion of long-term debt and excluding finance lease liabilities, as of December 31, 2024 was $ 3,110 million. The estimated fair value of the current portion of the Company's long-term debt, excluding finance lease liabilities, was $ 497 million as of December 31, 2024. 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.

Table of Contents

Debt - On May 1, 2025, the Company repaid $ 500 million aggregate principal amount of its 3.844 % senior notes upon their maturity. The repayment was funded using a combination of cash on hand and proceeds from the Company’s commercial paper program.

3. ACCOUNTING STANDARDS UPDATES

Recently Adopted Guidance

There were no new Accounting Standards Updates (“ASU”) adopted during the nine months ended September 30, 2025 that had a material impact on the Company’s consolidated financial statements.

Accounting Guidance Issued But Not Adopted as of September 30, 2025

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.

Other accounting pronouncements issued but not effective until after December 31, 2025, are not expected to have a material impact on the Company's consolidated financial position, results of operations, or cash flows.

4. ACQUISITIONS

In January 2025, the Company acquired substantially all of the assets of W International SC, LLC and Vivid Empire SC, LLC (collectively “W International”), a South Carolina-based complex metal fabricator specializing in the manufacture of shipbuilding structures, modules, and assemblies, for a purchase price of $ 132 million.

9. INCOME TAXES

The Company's earnings are primarily domestic, and its effective income tax rates on earnings from operations for the three months ended September 30, 2025 and 2024, were 28.9 % and 9.8 %, respectively. For the nine months ended September 30, 2025 and 2024, the Company's effective income tax rates on earnings from operations were 23.0 % and 16.6 %, respectively. The higher effective tax rates for the three and nine months ended September 30, 2025, were primarily attributable to a reduction in the estimated research and development tax credits for the prior period recorded in the current period.

For the three and nine months ended September 30, 2025, the Company’s effective tax rates differed from the federal statutory corporate income tax rate of 21 % primarily due to a reduction in the estimated research and development tax credits for the prior period recorded in the current period.

The Company's unrecognized tax benefits decreased by $ 6 million during the three months ended September 30, 2025, and increased by less than $ 1 million during the nine months ended September 30, 2025. As of September 30, 2025, the estimated amounts of the Company's unrecognized tax benefits, excluding interest and penalties, were liabilities of $ 110 million. Assuming a sustainment of these tax positions, a reversal of $ 86 million of the accrued amounts would favorably affect the Company's effective federal income tax rate in future periods.

Table of Contents

The Company recognizes interest and penalties related to unrecognized tax benefits as income tax expense. For the three and nine months ended September 30, 2025, interest and penalties resulting from the unrecognized tax benefits noted above increased income tax expense by $ 2 million and $ 5 million, respectively.

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.

IRS Audits - The Company has reached an agreement in principle with the IRS on the research and development tax credits for the 2016-2021 tax years. The agreement is going through IRS administrative review processes and is subject to review by the Joint Committee on Taxation. The Company believes that its unrecognized tax benefits are adequate and will cover the expected impact of the agreement with the IRS.

On July 4, 2025, Public Law 119-21 (the “Act”) was signed into law. The Act provides for significant changes to the U.S. Internal Revenue Code of 1986, as amended, that impact corporations, including making certain business deductions permanent, such as bonus depreciation and immediate expensing of domestic research and development expenditures. In addition, the Act allows an acceleration of the deduction for the remaining unamortized domestic research and development expenditures capitalized during the 2022 through 2024 tax years. These unamortized expenditures can be deducted over one or two years . The Company recorded the impact of the following significant items as of September 30, 2025:

Domestic research and development expenditures : The Company recorded a current tax benefit of $ 109 million based on its intent to expense all current year domestic research and development expenditures and to accelerate the deduction for the remaining unamortized domestic research and development expenditures capitalized during the 2022 through 2024 tax years over a two year period. This resulted in an increase of approximately $ 109 million to the Company’s current income taxes receivable and a corresponding increase in its net deferred tax liability.

Bonus Depreciation: While the Company has not completed its analysis of all capital expenditures that may qualify for immediate expensing, the Company recorded an estimated current tax benefit of $ 33 million based on its intent to fully expense all qualified property acquired and placed into service after January 19, 2025. This resulted in an increase of approximately $ 33 million to the Company’s current income taxes receivable and a corresponding increase in its net deferred tax liability.

10. 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 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. The Fourth Circuit Court of Appeals reversed the dismissal and remanded the case to the District Court for further proceedings. The Company cannot at this time predict or reasonably estimate the outcome of this matter.

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. No assurances can be provided regarding the ultimate resolution 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.

During the third quarter of 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 nine months ended September 30, 2025 and 2024, 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. Although, 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, the Company 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 these matters.

11. 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 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 September 30, 2025 and December 31, 2024, the Company did not have any accrued receivables related to insurance reimbursements or recoveries for environmental matters.

Table of Contents

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 September 30, 2025, 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 September 30, 2025, 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.

Other Matters - The Company previously disclosed an issue regarding the degree of corrosion of certain steel plates used to fabricate Friedman (NSC 11). During the second quarter of 2025, the Company reached an agreement with the customer to resolve the matter. The resolution of the matter did not have a material impact to the Company's consolidated financial position, results of operations, or cash flows.

Collective Bargaining Agreements - Of the Company's approximately 44,000 employees, 45 % are covered by a total of nine 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 2026. Approximately 15 Mission Technologies employees in Klamath Falls, Oregon are covered by one collective bargaining agreement that expires in June 2029.

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.

12. EMPLOYEE PENSION AND OTHER POSTRETIREMENT BENEFITS

The Company provides eligible employees defined benefit pension plans, defined contribution benefit plans, and other postretirement benefit plans.

The costs of the Company's defined benefit pension plans and other postretirement benefit plans for the three and nine months ended September 30, 2025 and 2024, were as follows:

13. STOCK COMPENSATION PLANS

During the nine months ended September 30, 2025 and 2024, the Company issued new stock awards as follows:

Restricted Performance Stock Rights - For the nine months ended September 30, 2025, the Company granted approximately 0.2 million RPSRs at a weighted average share price of $ 168.89 . These rights are subject to cliff vesting on December 31, 2027. For the nine months ended September 30, 2024, the Company granted approximately 0.1 million RPSRs at a weighted average share price of $ 288.26 . These rights are subject to cliff vesting on December 31, 2026. 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 nine months ended September 30, 2025, the Company granted approximately 0.1 million compensation RSRs at a weighted average share price of $ 169.78 . For the nine months ended September 30, 2024, the Company granted approximately 0.1 million compensation RSRs at a weighted average share price of $ 287.91 . 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 nine months ended September 30, 2025, the Company granted approximately 1,300 retention RSRs at a weighted average share price of $ 189.38 , with cliff vesting one to two years from the grant date. For the nine months ended September 30, 2024, the Company granted approximately 2,200 retention RSRs at a weighted average share price of $ 281.01 , with cliff vesting one to two years from the grant date.

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.

Table of Contents

Stock award activity for the nine months ended September 30, 2025, and 2024, was as follows:

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

OVERVIEW

Our Business

Huntington Ingalls Industries, Inc. ("HII", "we", "us", or "our") 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. For more than a century, our Ingalls Shipbuilding segment ("Ingalls") in Mississippi and Newport News Shipbuilding segment ("Newport News") in Virginia have built more ships in more ship classes than any other U.S. naval shipbuilder, making us America's largest shipbuilder. Our Mission Technologies segment develops integrated technology solutions and products that enable today's connected, all-domain force. Headquartered in Newport News, Virginia, we employ approximately 44,000 people domestically and internationally.

We conduct most of our business with the U.S. Government, primarily the Department of War (the "Department"). As prime contractor, principal subcontractor, team member, or partner, we participate in many high-priority U.S. defense programs. Ingalls includes our non-nuclear ship design, construction, repair, and maintenance businesses. Newport News includes all of our nuclear ship design, construction, overhaul, refueling, and repair and maintenance businesses. Our Mission Technologies segment is organized into four groups, All-Domain Operations, Warfare Systems, Global Security, and Uncrewed Systems, and specializes in a wide range of services and products across our capabilities, which include command, control, computers, communications, cyber, intelligence, surveillance, and reconnaissance ("C5ISR") systems and operations; the application of artificial intelligence and machine learning to battlefield decisions; defensive and offensive cyber, electronic warfare & space; unmanned systems; live, virtual, and constructive training solutions; fleet sustainment; and critical nuclear operations.

The following discussion should be read along with the unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q, as well as our Annual Report on Form 10-K for the year ended December 31, 2024 (our "2024 Annual Report on Form 10-K").

Business Environment

The federal budget environment remains a significant long-term risk, and we continue to see uncertainty in the economy, our industry, and our company. Our customers and suppliers continue to face challenges, and we believe continued budget pressures could have serious implications for defense discretionary spending, the defense industrial base, including HII, and the customers, employees, suppliers, subcontractors, investors, and communities that rely on companies in the defense industrial base. We cannot clearly predict how long these challenges will

Table of Contents

continue, whether these challenges will change over time, or whether our actions to address these challenges will be successful.

Defense Spending Environment – On May 2, 2025, the Trump Administration released the President's topline recommendations on discretionary funding levels for fiscal year 2026, followed by detailed budget justification documents in June. Additionally, under the Public Law 119-21 (the "Act"), Congress provided mandatory funding for more than $29 billion for Shipbuilding and the Maritime Industrial Base. This funding included one Virginia class (SSN 774) fast attack submarine and two Arleigh-Burke class (DDG 51) guided-missile destroyers, and provided additional funding for amphibious warfare ships and unmanned surface vessels.

Lawmakers continue to consider the annual budget request for the federal government. The U.S. House of Representatives approved a fiscal year 2026 defense appropriations measure in July, and the U.S. Senate Committee on Appropriations advanced its defense appropriations measure out of committee in July. The House and Senate Committees on Armed Services acted on their respective National Defense Authorization bills for fiscal year 2026, with the House approving the authorization bill in September and the Senate approving the authorization bill in October.

Fiscal year 2026 began on October 1, 2025 without annual appropriations legislation or a continuing resolution. As a result, many parts of the U.S. Government temporarily shut down. This lapse in federal funding leaves the federal government sustaining only those activities that are determined to be excepted or funded through means other than fiscal year 2026 annual appropriations.

Prior to the lapse in appropriations, the Department identified those missions and functions of the Department deemed high priority, including shipbuilding, that may continue through the use of available funds in the absence of new annual appropriations. Funds that remain available include those provided for certain shipbuilding programs under the Act.

According to Department guidance, “The expiration of an appropriation does not require the termination of contracts (or issuance of stop work orders) funded by that appropriation unless a new obligation of funds is required under the contract and the contract is not required to support an excepted activity." "The Department may continue to enter into new contracts, or place task orders under existing contracts, to obtain supplies and services necessary to carry out or support excepted activities even though there are no available appropriations.”

It remains uncertain at this point when funding will be enacted for fiscal year 2026 and whether it will be in the form of a continuing resolution or finalization of annual appropriations measures. We cannot predict the outcome of the fiscal year 2026 budget process, including any impact on the Company's programs.

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.

For further information on our business environment, see the discussion under Business Environment under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of our 2024 Annual Report on Form 10-K.

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.

Table of Contents

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 and nine months ended September 30, 2025, increased $443 million, or 16%, and $477 million, or 6%, respectively compared to the same periods in 2024, primarily due to higher volumes at Newport News, Ingalls, and Mission Technologies.

Net Cumulative Catch-up Revenue Adjustments

For the three and nine months ended September 30, 2025 and 2024, favorable and unfavorable cumulative catch-up revenue adjustments were as follows:


	Three Months Ended September 30				Nine Months Ended September 30

($ in millions)	2025		2024		2025		2024
Gross favorable adjustments	$	37	$	36	$	255	$	174
Gross unfavorable adjustments	(40)		(108)		(268)		(220)
Net adjustments	$	(3)	$	(72)	$	(13)	$	(46)

See Note 7: 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 each of the three and nine months ended September 30, 2025, decreased $7 million from the same periods in 2024, primarily due to lower overhead costs.

Table of Contents

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 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 September 30								Nine Months Ended September 30
					2025 vs. 2024								2025 vs. 2024
($ in millions)	2025		2024		Dollars		Percent		2025		2024		Dollars		Percent

Non-current state income taxes	9		(1)		10		1,000	%	12		(3)		15		500	%
Segment operating income	$	179	$	97	$	82	85	%	$	522	$	470	$	52	11	%

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.

Table of Contents

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


	Three Months Ended September 30								Nine Months Ended September 30
					2025 vs. 2024								2025 vs. 2024
($ in millions)	2025		2024		Dollars		Percent		2025		2024		Dollars		Percent
FAS benefit	$	25	$	15	$	10	67	%	$	75	$	48	$	27	56	%
CAS cost	14		13		1		8	%	43		38		5		13	%
FAS/CAS Adjustment	39		28		11		39	%	118		86		32		37	%
Non-operating retirement benefit	(48)		(44)		(4)		(9)	%	(143)		(134)		(9)		(7)	%
Operating FAS/CAS Adjustment expense	$	(9)	$	(16)	$	7	44	%	$	(25)	$	(48)	$	23	48	%

The Operating FAS/CAS Adjustment was a net expense of $9 million and $16 million for the three months ended September 30, 2025 and 2024, respectively. The Operating FAS/CAS Adjustment was a net expense of $25 million and $48 million for the nine months ended September 30, 2025 and 2024, respectively. The favorable change in the Operating FAS/CAS Adjustment for each period was primarily driven by higher interest rates under FAS.

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.

Non-current state income tax expense was $9 million for the three months ended September 30, 2025, compared to a non-current state income tax benefit of $1 million for the three months ended September 30, 2024. Non-current state income tax expense was $12 million for the nine months ended September 30, 2025, compared to a non-current state income tax benefit of $3 million for the nine months ended September 30, 2024. The unfavorable changes in non-current state income taxes for the three and nine months ended September 30, 2025 were driven by an increase in deferred state income tax expense, primarily attributable to a change in net capitalized research and development expenditures.

SEGMENT OPERATING RESULTS

Our discussion of business segment performance focuses on sales and service revenues and operating income, consistent with our approach for managing our business. We are aligned into three reportable segments: Ingalls, Newport News, and Mission Technologies.

Segment Operating Income

Newport News segment operating income for the three months ended September 30, 2025, was $80 million, compared to segment operating income of $15 million for the same period in 2024. The increase was primarily driven by unfavorable cumulative catch-up adjustments in the Virginia class (SSN 774) submarine program and aircraft carriers in 2024.

Newport News segment operating income for the nine months ended September 30, 2025, was $247 million, compared to segment operating income of $208 million for the same period in 2024. The increase was primarily driven by risk retirement in the Columbia class (SSBN 826) submarine program and contract adjustments in the Virginia class (SSN 774) submarine program, partially offset by contract adjustments and incentives in 2024 in the RCOH program.

Product sales for the nine months ended September 30, 2025, increased $268 million, or 5%, from the same period in 2024, primarily due to higher volumes in submarines at Newport News and surface combatants at Ingalls, partially offset by lower volumes in amphibious assault ships at Ingalls.

Segment cost of product sales for the nine months ended September 30, 2025, increased $261 million, or 6%, compared with the same period in 2024, primarily due to the changes in volume described above.

Service Revenues and Segment Cost of Service Revenues

Service revenues for the three months ended September 30, 2025, increased $132 million, or 13%, from the same period in 2024, primarily due to higher volumes in C5ISR and live, virtual, and constructive training solutions at Mission Technologies, higher volumes in naval nuclear support services and aircraft carriers at Newport News, and higher volumes in surface combatants at Ingalls.

Segment cost of service revenues for the nine months ended September 30, 2025, increased $185 million, or 7%, compared with the same period in 2024, primarily due to the higher volumes described above.

OTHER FINANCIAL INFORMATION

Interest Expense

Interest expense for the three months ended September 30, 2025, was $23 million, which was consistent with the same period in 2024. There were no individually significant drivers for interest expense during the period.

Interest expense for the nine months ended September 30, 2025, was $79 million, compared to $68 million for the same period in 2024. The increase in interest expense for the nine months ended September 30, 2025 was driven by an increase in outstanding long-term debt compared to the prior year 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 and nine months ended September 30, 2025, the non-operating retirement benefit was $48 million and $143 million, respectively, compared with $44 million and $134 million, respectively, for the same periods in 2024. The favorable change in the non-operating retirement benefit for both periods was primarily driven by the amortization of net actuarial costs.

Other, Net

Other, net income for the three and nine months ended September 30, 2025, was $18 million and $30 million, respectively, compared with other, net income of $9 million and $21 million, respectively, for the same periods in 2024. The increase in other, net income for both periods was primarily driven by an increase in unrealized gains on investments.

Federal and Foreign Income Taxes

Our effective income tax rates on earnings from operations for the three months ended September 30, 2025 and 2024, were 28.9 % and 9.8 %, respectively. Our effective income tax rates on earnings from operations for the nine months ended September 30, 2025 and 2024, were 23.0 % and 16.6 %, respectively. The higher effective tax rates for the three and nine months ended September 30, 2025, were primarily attributable to a reduction in the estimated research and development tax credits for the prior period recorded in the current period.

For each of the three and nine months ended September 30, 2025, our effective tax rate differed from the federal statutory corporate income tax rate of 21 % primarily due to a reduction in the estimated research and development tax credits for the prior period recorded in the current period.

BACKLOG

Total backlog as of September 30, 2025, and December 31, 2024, was $55.7 billion and $48.7 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 September 30, 2025 and December 31, 2024, respectively.

Table of Contents

The following table presents funded and unfunded backlog by segment as of September 30, 2025, and December 31, 2024:


	September 30, 2025						December 31, 2024
($ in millions)	Funded		Unfunded		Total Backlog		Funded		Unfunded		Total Backlog
Ingalls	$	15,640	$	2,906	$	18,546	$	13,519	$	2,333	$	15,852
Newport News	15,586		15,420		31,006		12,079		14,666		26,745
Mission Technologies	1,970		4,157		6,127		1,824		4,292		6,116
Total backlog	$	33,196	$	22,483	$	55,679	$	27,422	$	21,291	$	48,713

We expect approximately 21% of the $48.7 billion total backlog as of December 31, 2024, to be converted into sales in 2025. U.S. Government orders comprised substantially all of the backlog as of September 30, 2025 and December 31, 2024.

Contract Awards

The value of new contract awards during the nine months ended September 30, 2025, was approximately $16.0 billion, primarily driven by awards at Newport News and Ingalls, inclusive of a contract modification for construction of two additional Block V Virginia -class submarines.

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 provided by 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 provided by operating activities:


	Nine Months Ended September 30				2025 vs. 2024

($ in millions)	2025		2024		Dollars
Net earnings	$	446	$	427	$	19
Depreciation and amortization of purchased intangibles	242		242		—
Stock-based compensation	43		15		28

Deferred income taxes	121		(55)		176

Trade working capital increase	(177)		(528)		351
Net cash provided by operating activities	$	546	$	2	$	544

We have historically maintained a capital structure comprised of a mix of equity and debt financing. We vary our leverage both to optimize our equity return and to pursue acquisitions. 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

We discuss below our significant operating, investing, and financing activities affecting cash flows for the nine months ended September 30, 2025 and 2024, as classified in our unaudited condensed consolidated statements of cash flows.

Table of Contents

Operating Activities

Cash provided by operating activities for the nine months ended September 30, 2025, was $546 million, compared with cash provided by operating activities of $2 million for the same period in 2024. The change in operating cash flow was primarily due to a favorable change in trade working capital driven by the timing of billings across programs and lower payments for income taxes.

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 October 1, 2025, and beyond such twelve-month period based on our current business plans.

Investing Activities

Cash used in investing activities for the nine months ended September 30, 2025, was $387 million, compared to $238 million used in investing activities for the same period in 2024. The change in investing cash was primarily driven by the acquisition of W International.

For 2025, 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 2.0% to 2.5% 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 nine months ended September 30, 2025, was $678 million, compared with $184 million used in financing activities for the same period in 2024. The change in cash used in financing activities was primarily due to a $396 million decrease in proceeds from our commercial paper program and a $271 million increase in repayments of long term debt, partially offset by a decrease of $162 million in common stock repurchases.

Free Cash Flow

Free cash flow represents cash provided by 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 provided by 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 provided by operating activities to free cash flow:


	Nine Months Ended September 30				2025 vs. 2024

($ in millions)	2025		2024		Dollars
Net cash provided by operating activities	$	546	$	2	$	544
Less capital expenditures:
Capital expenditure additions	(268)		(253)		(15)
Grant proceeds for capital expenditures	6		14		(8)
Free cash flow	$	284	$	(237)	$	521

Free cash flow for the nine months ended September 30, 2025, increased $521 million from the same period in 2024, primarily due to a favorable change in trade working capital driven by the timing of billings across programs and lower payments for income taxes.

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 September 30, 2025 and 2024, 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 September 30, 2025, $11 million in letters of credit were issued but undrawn and $368 million of surety bonds were outstanding. As of September 30, 2025, we had no other significant off-balance sheet arrangements.

FORWARD-LOOKING STATEMENTS AND PROJECTIONS

Statements in this Quarterly Report on Form 10-Q and in our other filings with the SEC, as well as other statements we may make from time to time, other than statements of historical fact, constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. In some cases, you can identify forward-looking statements by words such as "may," "will," "should," "expects," "intends," "plans," "anticipates," "believes," "estimates," "guidance," "outlook," "predicts," "potential," "continue," and similar words or phrases or the negative of these words or phrases. These statements relate to future events or our future financial performance and involve known and unknown risks, uncertainties, and other factors that may cause our actual results, levels of activity, performance, or achievements to be materially different from any future results, levels of activity, performance, or achievements expressed or implied by these forward-looking statements. Although we believe the expectations reflected in the forward-looking statements are reasonable when made, we cannot guarantee future results, levels of activity, performance, or achievements. There are a number of important factors that could cause our actual results to differ materially from the results anticipated by our forward-looking statements, which include, but are not limited to:

• our dependence on the U.S. Government for substantially all of our business;

• significant delays or reductions in appropriations for our programs and/or changes in customer priorities and requirements (including government budgetary constraints, government shutdowns, shifts in defense spending, and changes in customer short-range and long-range plans);

• our ability to estimate our future contract costs, including cost increases due to inflation, labor challenges, changes in trade policy, or other factors and our efforts to recover or offset such costs and/or changes in estimated contract costs, and perform our contracts effectively;

• changes in business practices, procurement processes and government regulations and our ability to comply with such requirements;

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 Frank E. Petersen Jr. (DDG 121), USS Lenah H. Sutcliffe Higbee (DDG 123), and USS Jack H. Lucas (DDG 125) in 2021, 2022, and 2023, respectively. We have contracts to construct the following Arleigh Burke class (DDG 51) destroyers: Ted Stevens (DDG 128), 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), and Richard J. Danzig (DDG 143).

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. We have a teaming agreement with Electric Boat to build modules for the entire Columbia class (SSBN 826) submarine program that leverages our Virginia class (SSN 774) experience. 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.

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 planned for this program, of which the first ten ships have been delivered. In Q2 2025, we reached agreement with the U.S. Coast Guard to terminate production and delivery of the 11th 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.

San Antoni o 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 delivered USS Fort Lauderdale (LPD 28), and 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 September 30, 2025, 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.
