HUNTINGTON INGALLS INDUSTRIES, INC.

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 solutions 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, 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 $234 million and $233 million as of March 31, 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 values of the Company's total long-term debt, including the current portion of long-term debt and excluding finance lease liabilities, as of March 31, 2025, and December 31, 2024, were $3,150 million and $3,110 million, respectively. The estimated fair values of the current portion of the Company's long-term debt, excluding finance lease liabilities, were $500 million and $497 million as of March 31, 2025, and December 31, 2024, 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.

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

As of March 31, 2025, the Company had $1,688 million unutilized under its Second Amended and Restated Revolving Credit Facility ("Credit Facility"). The Credit Facility contains customary affirmative and negative covenants and events of default, as well as a financial covenant based on a maximum total leverage ratio. The maximum total leverage ratio covenant limited the Company's borrowing capacity under the Credit Facility to $1,364 million as of March 31, 2025. Subsequent to the repayment of the 3.844% senior notes on May 1, 2025, the Company's borrowing capacity under the Credit Facility is no longer limited by the maximum total leverage ratio covenant.

3. ACCOUNTING STANDARDS UPDATES

Recently Adopted Guidance

There were no new Accounting Standard Updates (“ASU”) adopted during the three months ended March 31, 2025 that had a material impact on the Company’s consolidated financial statements.

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

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 $133 million, subject to customary purchase price adjustments. The acquired manufacturing facility expands the Company’s shipbuilding capacity and operates within the Newport News segment. The transaction closed using cash on hand and qualifies as a business combination under FASB Accounting Standards Codification (“ASC”) 805 – "Business Combinations."

The Company recognized $33 million of goodwill, which includes expected synergies and the value of W International’s acquired workforce, all of which was allocated to the Newport News segment and is tax deductible. There have been no other changes to the Company’s goodwill since December 31, 2024.

The Company is in the process of completing its acquisition accounting, including its fair value estimates for certain assets and liabilities. The assets, liabilities, and results of operations of W International are not material to the Company’s consolidated financial position, results of operations, or cash flows.

5. 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 the three months ended March 31, 2025, the Company did not repurchase any shares. For the three months ended March 31, 2024, the Company repurchased 223,329 shares at an aggregate cost of $63

million, including $1 million of accrued excise tax. 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 $53 million and $51 million for the three months ended March 31, 2025 and 2024, 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 $27 million and $28 million as of March 31, 2025, and December 31, 2024, respectively.

The changes in accumulated other comprehensive loss by component for the three months ended March 31, 2025 and 2024, were as follows:

1 These accumulated comprehensive loss components are included in the computation of net periodic benefit cost. See Note 12: Employee Pension and Other Postretirement Benefits. The tax expense recorded in stockholders' equity for the amounts reclassified from accumulated other comprehensive loss for the three months ended March 31, 2025 and 2024, was less than $1 million and $2 million, respectively.

6. EARNINGS PER SHARE

Basic and diluted earnings per common share were calculated as follows:

Under the treasury stock method, the Company has excluded from the diluted share amounts presented above the effects of 0.4 million Restricted Performance Stock Rights ("RPSRs") for each of the three months ended March 31,

2025 and 2024, and 0.2 million and 0.1 million Restricted Stock Rights ("RSRs") for the three months ended March 31, 2025 and 2024, respectively.

7. REVENUE

Disaggregation of Revenue

The following tables present revenues on a disaggregated basis:

As of March 31, 2025, the Company had $48.0 billion of remaining performance obligations. The Company expects to recognize approximately 40% of its remaining performance obligations as revenue through 2026, an additional 30% through 2028, 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:

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 continues to experience 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.

For the three months ended March 31, 2024, 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.

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:

The Company’s net contract assets increased $461 million from December 31, 2024 to March 31, 2025, 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 $552 million and $641 million for the three months ended March 31, 2025 and 2024, respectively.

8. SEGMENT INFORMATION

The following tables present the Company's operating results by segment:

Sales transactions between segments are generally recorded at cost.

Other segment items consists of general and administrative expenses and other income and gains (losses), net.

Other Financial Information

The following tables present the Company's capital expenditures, as presented to the chief operating decision maker, and depreciation and amortization by segment:

1 Net of grant proceeds for capital expenditures

Asset information by segment is not disclosed because it is not a key measure of performance used by the chief operating decision maker.

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 March 31, 2025 and 2024, were 20.3% and 16.8%, respectively. The higher effective tax rate for the three months ended March 31, 2025, was primarily attributable to excess tax benefits recognized on stock-based compensation recorded in the prior period.

For the three months ended March 31, 2025, the Company’s effective tax rate differed from the federal statutory corporate income tax rate of 21% primarily due to research and development tax credits for the current period.

The Company's unrecognized tax benefits increased by $3 million during the three months ended March 31, 2025. As of March 31, 2025, the estimated amounts of the Company's unrecognized tax benefits, excluding interest and penalties, were liabilities of $113 million. Assuming a sustainment of these tax positions, a reversal of $92 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, 2025, interest and penalties resulting from the unrecognized tax benefits noted above increased income tax expense by $2 million.

IRS Audits – In February 2025, the IRS notified the Company that its 2018 research and development tax credit refund claim would be processed and assigned to IRS exam for audit. See Note 11: Income Taxes of the Company’s 2024 Annual Report on Form 10-K for additional information.

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.

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, and the plaintiffs have

appealed the District Court dismissal to the Fourth Circuit Court of Appeals. 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 three months ended March 31, 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.

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 March 31, 2025 and December 31, 2024, 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, 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 March 31, 2025, the Company had $12 million in issued but undrawn letters of credit and $389 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). The Company’s expectation regarding the resolution of the matter with the customer is included in contract cost and profit estimates. Those estimates include management's best assessment of the underlying causal events, contractual entitlements, and the probability of successful resolution with the customer. The Company does not expect the final resolution of the matter to have a material impact to the Company's consolidated financial position, results of operations, or cash flows.

Collective Bargaining Agreements - Of the Company's over 44,000 employees, approximately 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 2027, December 2027 and April 2029. 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 2025.

Collective bargaining agreements generally expire after three years 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 months ended March 31, 2025 and 2024, were as follows:

The Company made the following contributions to its defined benefit pension plans and other postretirement benefit plans for the three months ended March 31, 2025 and 2024:

As of March 31, 2025, the Company anticipates no further significant cash contributions to its qualified defined benefit pension plans in 2025.

13. STOCK COMPENSATION PLANS

During the three months ended March 31, 2025 and 2024, the Company issued new stock awards as follows:

Restricted Performance Stock Rights - 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. For the three months ended March 31, 2024, the Company granted approximately 0.1 million RPSRs at a weighted average share price of $288.33. 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 three months ended March 31, 2025, the Company granted approximately 0.1 million compensation RSRs at a weighted average share price of $168.81. For the three months ended March 31, 2024, the Company granted approximately 0.1 million compensation RSRs at a weighted average share price of $288.33. 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, 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. For the three months ended March 31, 2024, the Company granted approximately 1,200 retention RSRs at a weighted average share price of $288.53, 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.

Stock award activity for the three months ended March 31, 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 over 44,000 people domestically and internationally.

We conduct most of our business with the U.S. Government, primarily the Department of Defense ("DoD"). 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; uncrewed 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 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 2025 budget cycle ultimately concluded with the passage of the Full-Year Continuing Appropriations and Extensions Act, 2025, signed into law March 15, 2025. This marks the first time the DoD will operate under a Continuing Resolution ("CR") for the full fiscal year. While unprecedented, exceptions were made to the Navy Shipbuilding and Conversion account in the full-year CR to provide the authorities and necessary funding levels for program execution. Final defense appropriations provided by the CR broadly supported shipbuilding programs, including funding for three Arleigh Burke class (DDG 51) guided missile destroyers, one Virginia class (SSN 774) fast attack submarine, one San Antonio class (LPD 17) Amphibious Transport Dock, the RCOH for USS Harry S. Truman (CVN 75), and funding to support Columbia class (SSBN 826) submarines, CVN, and LHA programs. The CR also included funding for the Submarine Industrial Base for investment in critical areas including supplier capacity and capability, strategic outsourcing, workforce training and technology and infrastructure, and multi-year procurement authority was provided for the Virginia class (SSN 774) program. An earlier short-term CR funding the government from December 20, 2024 through March 14, 2025 included additional supplemental funding for expenses necessary for procurement of two fiscal year 2024 Virginia class (SSN 774) submarines, one fiscal year 2025 Virginia class (SSN 774) submarine, and to incrementally fund contract obligations for the improvement of workforce wages and non-executive level salaries on new or existing contracts pertaining to the Virginia class (SSN 774) submarine program or to other nuclear-powered vessel 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. 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, 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.

Critical Accounting Policies, Estimates, and Judgments

As discussed in our 2024 Annual Report on Form 10-K, we consider our policies relating to the following matters to be critical accounting policies and estimates:

• Revenue recognition;
• Retirement related benefit plans; and
• Workers' compensation.

As of March 31, 2025, there had been no material changes to the foregoing critical accounting policies, estimates, and judgments since December 31, 2024.

Program Descriptions

For convenience, a brief description of certain programs discussed in this Quarterly Report on Form 10-Q is included in the "Glossary of Programs" in this section.

CONSOLIDATED OPERATING RESULTS

The following table presents selected financial highlights:

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 (the "FAR") 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, 2025, decreased $71 million, or 3%, compared to the same period in 2024, primarily due to lower volumes at Newport News, Ingalls, and Mission Technologies.

Net Cumulative Catch-up Revenue Adjustments

For the three months ended March 31, 2025 and 2024, favorable and unfavorable cumulative catch-up revenue adjustments were as follows:

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. The Company’s Newport News segment continues to experience 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 construction of Enterprise (CVN 80) and Virginia class (SSN 774) submarines, which were offset by contract incentives.

See Note 7: Revenue and "Segment Operating Results" in this section for additional information on our net cumulative catch-up revenue adjustments.

Cost of 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, 2025, increased $14 million from the same period in 2024, primarily due to higher overhead costs, partially offset by lower state income taxes.

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:

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:

The Operating FAS/CAS Adjustment was a net expense of $10 million and $17 million for the three months ended March 31, 2025 and 2024, respectively. The favorable change in the Operating FAS/CAS Adjustment 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 for the three months ended March 31, 2025 was less than $1 million, compared to non-current state income tax benefit of $1 million for the three months ended March 31, 2024. 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 the timing of long-term contract income for tax purposes.

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.

The following table presents segment operating results:

Key Segment Financial Measures

Refer to "Consolidated Operating Results" in this section for details related to sales and service revenues and segment operating income.

Net Cumulative Catch-up Revenue Adjustments by Segment

For the three months ended March 31, 2025 and 2024, net cumulative catch-up revenue adjustments by segment were as follows:

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. The Company’s Newport News segment continues to experience 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 construction of Enterprise (CVN 80) and Virginia class (SSN 774) submarines, which were offset by contract incentives.

See Note 7: Revenue and "Consolidated Operating Results" in this section for additional information on our net cumulative catch-up revenue adjustments.

Ingalls

Sales and Service Revenues

Ingalls revenues, including intersegment sales, for the three months ended March 31, 2025, decreased $18 million, or 3%, from the same period in 2024, primarily driven by lower volumes in amphibious assault ships.

Segment Operating Income

Ingalls segment operating income for the three months ended March 31, 2025, was $46 million, compared to segment operating income of $60 million for the same period in 2024. The decrease was primarily driven by lower performance on amphibious assault ships.

Newport News

The Company’s Newport News segment continues to experience performance challenges in the construction of aircraft carriers and the Virginia class (SSN 774) submarine program.

Sales and Service Revenues

Newport News revenues, including intersegment sales, for the three months ended March 31, 2025, decreased $38 million, or 3%, from the same period in 2024, primarily driven by lower volumes in aircraft carriers and naval nuclear support services, partially offset by higher volumes in the Columbia class (SSBN 826) submarine program.

Segment Operating Income

Newport News segment operating income for the three months ended March 31, 2025, was $85 million, compared to segment operating income of $82 million for the same period in 2024. The increase was primarily driven by contract incentives on the Virginia class (SSN 774) submarine program and higher volumes on the Columbia class (SSBN 826) submarine program, partially offset by lower performance on aircraft carrier construction.

Mission Technologies

Sales and Service Revenues

Mission Technologies revenues, including intersegment sales, for the three months ended March 31, 2025, decreased $15 million, or 2%, from the same period in 2024, primarily due to lower volumes in C5ISR, partially offset by higher volumes in cyber, electronic warfare & space.

Segment Operating Income

Mission Technologies segment operating income for the three months ended March 31, 2025, was $40 million, compared to segment operating income of $28 million for the same period in 2024. The increase was primarily driven by higher performance in cyber, electronic warfare & space and uncrewed systems.

PRODUCT AND SERVICE REVENUES AND COST ANALYSIS

The following table presents segment sales and service revenues and segment cost of sales and service revenues by both product and service:

1 Operating FAS/CAS Adjustment is excluded from segment cost of product sales and service revenues.

Product Sales and Segment Cost of Product Sales

Product sales for the three months ended March 31, 2025, decreased $74 million, or 4%, from the same period in 2024, primarily due to lower volumes in surface combatants and amphibious assault ships at Ingalls, and lower volumes in aircraft carriers, partially offset by higher volumes in the Columbia class (SSBN 826) submarine program at Newport News.

Segment cost of product sales for the three months ended March 31, 2025, decreased $80 million, or 5%, compared with the same period in 2024, primarily due to lower volumes described above.

Service Revenues and Segment Cost of Service Revenues

Service revenues for the three months ended March 31, 2025, increased $3 million from the same period in 2024, primarily as a result of higher volumes in surface combatant services at Ingalls, and higher volumes in cyber, electronic warfare & space at Mission Technologies, partially offset by lower volumes in naval nuclear support services at Newport News, and lower volumes in C5ISR at Mission Technologies.

Segment cost of service revenues for the three months ended March 31, 2025, decreased $3 million compared with the same period in 2024, primarily as a result of lower volumes in naval nuclear support service at Newport News, and lower volumes in C5ISR at Mission Technologies, partially offset by higher volumes in cyber, electronic warfare & space at Mission Technologies and higher volumes in surface combatant services at Ingalls.

OTHER FINANCIAL INFORMATION

Interest Expense

Interest expense for the three months ended March 31, 2025, was $28 million, compared with $21 million for the same period in 2024. The increase in interest expense for the three months ended March 31, 2025, was driven by an increase in outstanding long-term debt from 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 months ended March 31, 2025, the non-operating retirement benefit was $48 million, compared with $44 million for the same period in 2024. The increase in the non-operating retirement benefit was primarily driven by the amortization of net actuarial costs.

Other, Net

Other, net income for the three months ended March 31, 2025, was $6 million, compared with other, net income of $7 million for the same period in 2024.

Federal and Foreign Income Taxes

Our effective income tax rates on earnings from operations for the three months ended March 31, 2025 and 2024, were 20.3% and 16.8%, respectively. The higher effective tax rate for the three months ended March 31, 2025, was primarily attributable to excess tax benefits recognized on stock-based compensation recorded in the prior period.

For the three months ended March 31, 2025, our effective tax rate differed from the federal statutory corporate income tax rate of 21% primarily due to research and development tax credits for the current period.

BACKLOG

Total backlog as of March 31, 2025, and December 31, 2024, was $48.0 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 March 31, 2025 and December 31, 2024, respectively.

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

We expect approximately 22% 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 March 31, 2025 and December 31, 2024.

Contract Awards

The value of new contract awards during the three months ended March 31, 2025, was approximately $2.1 billion, primarily driven by awards at Newport News.

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:

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 three months ended March 31, 2025 and 2024, as classified in our unaudited condensed consolidated statements of cash flows.

Operating Activities

Cash used in operating activities for the three months ended March 31, 2025, was $395 million, compared with cash used in operating activities of $202 million for the same period in 2024. The change in operating cash flow was primarily due to an unfavorable change in trade working capital driven by the timing of billings across programs.

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 12 calendar months beginning April 1, 2025, and beyond such 12-month period based on our current business plans.

Investing Activities

Cash used in investing activities for the three months ended March 31, 2025, was $199 million, compared to $71 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 three months ended March 31, 2025, was $70 million, compared with $147 million used in financing activities for the same period in 2024. The change in cash used in financing activities was primarily due to a decrease of $62 million in common stock repurchases.

Free Cash Flow

Free cash flow represents cash provided by (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 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 used in operating activities to free cash flow:

Free cash flow for the three months ended March 31, 2025, decreased $188 million from the same period in 2024, primarily due to an unfavorable change in trade working capital driven by the timing of billings across programs.

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 significant deficiencies exist in one or more such systems. As of March 31, 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 March 31, 2025, $12 million in letters of credit were issued but undrawn and $389 million of surety bonds were outstanding. As of March 31, 2025, we had no other significant off-balance sheet arrangements.

ACCOUNTING STANDARDS UPDATES

See Note 3: Accounting Standards Updates in Part I, Item 1 for further information.

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.

USS 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 11 ships planned for this program, of which the first ten ships have been delivered.

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 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 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 March 31, 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.

Item 4. Controls and Procedures
