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, 2022 (the "2022 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. The effects of this practice only exist 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 $217 million and $209 million as of June 30, 2023, and December 31, 2022, respectively, and are presented within miscellaneous other assets within 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 current portion) as of June 30, 2023, and December 31, 2022, were $2,224 million and $2,703 million, respectively. The estimated fair values of the current portion of the Company's long-term debt were $482 million and $390 million as of June 30, 2023 and December 31, 2022, 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 under the fair value hierarchy.

5

Debt - In April 2023, the Company amended its existing $1.5 billion credit facility (the "Revolving Credit Facility") and $650 million term loan due August 19, 2024 (the "Term Loan") to change the benchmark interest rate from the London Interbank Offered Rate to the Secured Overnight Financing Rate (“SOFR”). The current interest rate is based on SOFR plus an interest spread based on the Company's credit rating, plus an additional 0.10%. The Company does not expect the transition to the SOFR benchmark to materially impact its financial results. For further information on the Company's debt, see the Company's 2022 Annual Report on Form 10-K.

Goodwill Impairment and Annual Assessment Date Change - During the second quarter of 2023, the Company elected to change the measurement date of its annual goodwill impairment test from November 30 to October 31. The change is not material to the consolidated financial statements as it does not result in the delay, acceleration, or avoidance of an impairment charge, and the test is still performed in the fourth quarter. The Company continues to perform a quarterly assessment for impairment between annual tests for impairment.

Sale of Equity Method Investment - In June 2023, the Company sold its investment in its unconsolidated ship repair and specialty fabrication joint venture, Titan Acquisition Holdings, L.P. ("Titan"). The Company received $61 million in proceeds and recognized an immaterial loss on sale.

3. ACCOUNTING STANDARDS UPDATES

Accounting pronouncements issued but not effective until after December 31, 2023, are not expected to have a material impact on the Company's consolidated financial position, results of operations, and cash flows.

4. STOCKHOLDERS' EQUITY

Treasury Stock - In November 2019, the Company's board of directors authorized an increase in the Company's stock repurchase program from $2.2 billion to $3.2 billion and an extension of the term of the program to October 31, 2024. Repurchases are made from time to time at management's discretion in accordance with applicable federal securities laws. For the six months ended June 30, 2023, the Company repurchased 75,849 shares at an aggregate cost of $16 million. For the six months ended June 30, 2022, the Company repurchased 131,006 shares at an aggregate cost of $27 million. 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 $99 million and $94 million for the six months ended June 30, 2023 and 2022, 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 $592 million and $599 million as of June 30, 2023 and December 31, 2022, respectively.

The changes in accumulated other comprehensive loss by component for the three and six months ended June 30, 2023 and 2022, were as follows:

The tax expense recorded in stockholders' equity for the amounts reclassified from accumulated other comprehensive loss for the three months ended June 30, 2023 and 2022, was $1 million and $3 million, respectively. The tax expense recorded in stockholders' equity for the amounts reclassified from accumulated other comprehensive loss for the six months ended June 30, 2023 and 2022, was $2 million and $6 million, respectively.

8. INCOME TAXES

The Company's earnings are primarily domestic, and its effective income tax rates on earnings from operations for the three months ended June 30, 2023 and 2022, were 23.1% and 19.8%, respectively. For the six months ended June 30, 2023 and 2022, the Company's effective income tax rates on earnings from operations were 22.0% and 20.1%, respectively. The higher effective tax rate for each of the three and six months ended June 30, 2023, was primarily attributable to a tax gain associated with the sale of the Company's interest in Titan.

For each of the three and six months ended June 30, 2023, the Company's effective tax rate differed from the federal statutory corporate income tax rate primarily as a result of the tax gain associated with the sale of the Company’s interest in Titan. For the three months ended June 30, 2022, the Company's effective tax rate differed from the federal statutory corporate income tax rate primarily as a result of research and development tax credits. For the six months ended June 30, 2022, the Company's effective tax rate did not differ materially from the federal statutory corporate income tax rate of 21%.

The Company's unrecognized tax benefits increased by $2 million and $4 million during the three and six months ended June 30, 2023, respectively. As of June 30, 2023, the estimated amounts of the Company's unrecognized tax benefits, excluding interest and penalties, were liabilities of $94 million. Assuming a sustainment of these tax positions, a reversal of $71 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 and six months ended June 30, 2023, interest resulting from the unrecognized tax benefits noted above increased income tax expense by $1 million and $2 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 unrecognized state 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.

9. INVESTIGATIONS, CLAIMS, AND LITIGATION

The Company is involved in legal proceedings before various courts and administrative agencies, and is periodically subject to government examinations, inquiries and investigations. Pursuant to Financial Accounting Standards Board Accounting Standards Codification 450 Contingencies, the Company has accrued for losses associated with investigations, claims, and litigation when, and to the extent that, loss amounts related to the investigations, claims, and litigation are probable and can be reasonably estimated. The actual losses that might be incurred to resolve such investigations, claims, and litigation may be higher or lower than the amounts accrued. The Company has also provided 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.

False Claims Act Complaint - In 2016, the Company was made aware that it is a defendant in a qui tam False Claims Act lawsuit pending in the U.S. District Court for the Middle District of Florida related to the Company’s purchases of allegedly non-conforming parts from a supplier for use in connection with U.S. Government contracts. In August 2019, the Department of Justice (“DoJ”) declined to intervene in the lawsuit, and the lawsuit was unsealed. The court dismissed the complaint in September 2021, and the plaintiff has appealed the dismissal to the United States Court of Appeals for the 11th Circuit.

12

Insurance Claims - 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 has 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.

In September 2021, the Company filed a complaint in the Superior Court of Delaware, seeking a judgment against certain insurers for breach of contract and breach of the implied covenant of good faith and fair dealing under three representations and warranties insurance policies purchased in connection with the Company’s acquisition of Hydroid. The policies insure the Company against losses relating to the seller’s breach of certain representations and warranties in the Hydroid acquisition agreement. The coverage limit under the insurance policies is $70 million, and the Company believes it has incurred losses equal to at least that amount as a result of breaches of the acquisition agreement. 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.

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 six months ended June 30, 2023 and 2022, were not material individually or in the aggregate. The Company’s estimate of asbestos-related liabilities is subject to uncertainty because 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 Litigation - The Company and its predecessor-in-interest have been in litigation with the Bolivarian Republic of Venezuela (the "Republic") since 2002 over a contract for the repair, refurbishment, and modernization at Ingalls of two foreign-built frigates. Following an arbitration proceeding between the parties, in February 2018, the arbitral tribunal awarded the Company approximately $151 million on its claims and awarded the Republic approximately $22 million on its counterclaims. The Company is seeking to enforce and execute upon the award in multiple jurisdictions. No assurances can be provided regarding the ultimate resolution of this matter.

The Company is party to various other claims, legal proceedings, and investigations that arise in the ordinary course of business, including U.S. Government investigations 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 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.

10. COMMITMENTS AND CONTINGENCIES

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

13

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 cost to complete environmental remediation has been 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 estimated by management. These 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 June 30, 2023, the probable estimable future cost for environmental remediation was 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 June 30, 2023, the Company had $14 million in issued but undrawn letters of credit and $360 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 Contingencies - In 1985, the Company and the U.S. Navy entered into a settlement agreement to resolve disputes associated with billing and allocating to contracts the cost of workers’ compensation self-insurance, among other matters. Consistent with the 1985 settlement agreement, the Company has not recovered cumulative billable costs resulting from the different treatment of workers' compensation costs between CAS and FAS. Under the 1985 settlement agreement, these costs would be recovered in future periods. In December 2020, a U.S. Navy Contracting Officer issued a determination that the 1985 settlement agreement did not comply with CAS and directed the Company to develop and implement a different process to bill and allocate the cost of workers’ compensation self-insurance. The Company believes the 1985 settlement agreement is CAS-compliant and cannot be unilaterally terminated, but the Company is continuing to negotiate a resolution of the matter with the Contracting Officer.

The Company has been in negotiations with a Mission Technologies customer since January 2023 to address issues related to a manufacturing contract. The Company recorded provisions for contract loss in prior periods that were not material to the Company's consolidated financial position, results of operations, or cash flows. The parties have not agreed upon a resolution of the matter, and the Company could incur additional future losses on the contract. The Company can therefore not predict or give assurances regarding the ultimate outcome of this matter.

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 approximately 43,000 employees, approximately 45% are covered by a total of nine collective bargaining agreements and one site stabilization agreement. The Company believes its relationship with its employees is satisfactory.

Business Environment

We continue to see uncertainty in the economy, our industry, and our company, with challenges for customers and suppliers, labor shortages, supply chain challenges, and inflation, among other impacts.

U.S. Government Contracts - Congressional consideration of the fiscal year 2024 President’s Budget Request began following its release in March 2023 and is ongoing. The House and Senate have each acted on their respective National Defense Authorization bills for fiscal year 2024, both of which support our shipbuilding programs, including the additional authorization of the LPD 33 Flight II amphibious ship. Both House and Senate appropriations committees fund the procurement of two Virginia class (SSN 774) submarines, one Columbia class (SSBN 826) ballistic missile submarine, and two Arleigh Burke class (DDG 51) destroyers. The Senate appropriations bill provides advance procurement funding for LPD 33 (unnamed) in fiscal year 2024 and a third Arleigh Burke class (DDG 51) destroyer in fiscal year 2025, and the House appropriations bill includes language supporting a stable rate of procurement of amphibious warfare ships. All four committees have authorized the U.S. Navy to enter into one or more contracts for the multiyear procurement of the next block of Virginia class (SSN 774) submarines. We cannot predict the outcome of the fiscal year 2024 budget process or whether short-term funding will be required in the event annual appropriations measures are not finalized by the October 1 start of the fiscal year.

Political and Economic Environment - The global geopolitical and economic environment continues to be impacted

by uncertainty, heightened geopolitical tensions, and instability. Geopolitical relationships have changed, and are continuing 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 2022 Annual Report on Form 10-K.

Critical Accounting Policies, Estimates, and Judgments

As discussed in our 2022 Annual Report on Form 10-K, we consider our policies relating to the following matters to be critical accounting policies and estimates:

•Revenue recognition;

•Purchase accounting, goodwill, and intangible assets;

•Litigation, commitments, and contingencies;

•Retirement related benefit plans; and

•Workers' compensation.

As of June 30, 2023, there had been no material changes to the foregoing critical accounting policies, estimates, and judgments since December 31, 2022.

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

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 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 June 30, 2023, increased $125 million, or 5%, compared to the same period in 2022, primarily due to higher volumes at Newport News and Mission Technologies. Sales and service revenues for the six months ended June 30, 2023, increased $223 million, or 4%, compared to the same period in 2022, primarily due to higher volumes at Newport News and Mission Technologies, partially offset by lower volumes at Ingalls.

18

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 June 30, 2023, increased $11 million from the same period in 2022, primarily due to higher overhead costs. General and administrative expenses for the six months ended June 30, 2023, increased $14 million from the same period in 2022, primarily due to higher overhead costs and 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.

We internally manage our operations by reference to "segment operating income," which is defined as operating income before the Operating FAS/CAS Adjustment and non-current state income taxes, neither of which affects segment performance. Segment operating income is not a recognized measure under GAAP.  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. It is a measure we use to evaluate our core operating performance.  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. Refer to

"Segment Operating Results" in this section for details related to segment operating income, as well as activity within each segment.

The following table reconciles operating income to segment operating income:

	Three Months Ended June 30								Six Months Ended June 30
					2023 vs. 2022								2023 vs. 2022
($ in millions)	2023		2022		Dollars		Percent		2023		2022		Dollars		Percent

19

Operating income for the three months ended June 30, 2023, decreased $35 million compared with the same period in 2022, primarily due to lower segment operating income, partially offset by favorable changes in the Operating FAS/CAS Adjustment and non-current state income taxes. Operating income for the six months ended June 30, 2023, decreased $32 million compared with the same period in 2022, primarily due to lower segment operating income, partially offset by favorable changes in the Operating FAS/CAS Adjustment and non-current state income taxes.

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

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

	Three Months Ended June 30								Six Months Ended June 30
					2023 vs. 2022								2023 vs. 2022
($ in millions)	2023		2022		Dollars		Percent		2023		2022		Dollars		Percent
FAS benefit	$	7	$	19	$	(12)	(63)	%	$	15	$	43	$	(28)	(65)	%
CAS cost	13		13		—		—	%	23		23		—		—	%
FAS/CAS Adjustment	20		32		(12)		(38)	%	38		66		(28)		(42)	%
Non-operating retirement benefit	(37)		(67)		30		45	%	(74)		(138)		64		46	%
Operating FAS/CAS Adjustment	$	(17)	$	(35)	$	18	51	%	$	(36)	$	(72)	$	36	50	%

The Operating FAS/CAS Adjustment was a net expense of $17 million and $35 million for the three months ended June 30, 2023 and 2022, respectively. The Operating FAS/CAS Adjustment was a net expense of $36 million and $72 million for the six months ended June 30, 2023 and 2022, respectively. The favorable changes in the Operating FAS/CAS Adjustment of $18 million and $36 million for the three and six months ended June 30, 2023, respectively, were primarily driven by the more immediate recognition of 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 tax expense is charged to contract costs and included in cost of sales and service revenues in segment operating income.

Non-current state income tax benefit was $4 million and $1 million for the three months ended June 30, 2023 and 2022, respectively. Non-current state income tax benefit was $8 million and less than $1 million for the six months ended June 30, 2023 and 2022, respectively. The favorable change in non-current state income taxes for each period was driven by a decrease in deferred state income tax expense, primarily attributable to 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.

Segment Operating Income

Segment operating income reflects the aggregate performance results of contracts within a segment. Excluded from this measure are certain costs not directly associated with contract performance, such as the Operating FAS/CAS Adjustment and non-current state income taxes. Changes in segment operating income are typically expressed in terms of volume, as discussed 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") that 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, the effects of workforce stoppages, 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.

Cumulative Catch-up Revenue Adjustments

For the three and six months ended June 30, 2023 and 2022, favorable and unfavorable cumulative catch-up revenue adjustments were as follows:

	Three Months Ended June 30				Six Months Ended June 30

Sales and Service Revenues

Ingalls revenues, including intersegment sales, for the three months ended June 30, 2023, increased $6 million, or 1%, from the same period in 2022, primarily driven by higher revenues in surface combatants, partially offset by lower revenues in the Legend class National Security Cutter ("NSC") program.

Ingalls revenues, including intersegment sales, for the six months ended June 30, 2023, decreased $48 million, or 4%, from the same period in 2022, primarily driven by lower revenues in the NSC program and amphibious assault ships, partially offset by higher revenues in surface combatants.

Segment Operating Income

Ingalls segment operating income for the three months ended June 30, 2023, was $65 million, compared to segment operating income of $106 million for the same period in 2022. The decrease was primarily driven by lower favorable changes in contract estimates from facilities capital and economic price adjustment clauses and lower risk retirement on Harrisburg (LPD 30).

Ingalls segment operating income for the six months ended June 30, 2023, was $120 million, compared to segment operating income of $192 million for the same period in 2022. The decrease was primarily driven by lower favorable changes in contract estimates from facilities capital and economic price adjustment clauses and lower risk retirement on USS Fort Lauderdale (LPD 28) and Harrisburg (LPD 30).

Sales and Service Revenues

Newport News revenues, including intersegment sales, for the three months ended June 30, 2023, increased $76 million, or 5%, from the same period in 2022, primarily driven by higher revenues in aircraft carrier construction, the Columbia class (SSBN 826) submarine program, and the Virginia class (SSN 774) submarine program, partially offset by lower revenues in aircraft carrier refueling and complex overhaul ("RCOH").

22

Newport News revenues, including intersegment sales, for the six months ended June 30, 2023, increased $192 million, or 7%, from the same period in 2022, primarily driven by higher revenues in aircraft carrier construction, the Columbia class (SSBN 826) submarine program, and the Virginia class (SSN 774) submarine program, partially offset by lower revenues in naval nuclear support services.

Segment Operating Income

Newport News segment operating income for the three months ended June 30, 2023, was $95 million, compared to segment operating income of $94 million for the same period in 2022. Current year results were consistent with the prior year, as favorable Virginia class (SSN 774) submarine program revenue adjustments were offset by lower favorable changes in contract estimates from facilities capital and economic price adjustment clauses.

Newport News segment operating income for the six months ended June 30, 2023, was $179 million, compared to segment operating income of $175 million for the same period in 2022. The increase was primarily due to favorable Virginia class (SSN 774) submarine program revenue adjustments, partially offset by lower risk retirement on Enterprise (CVN 80) and lower favorable changes in contract estimates from facilities capital and economic price adjustment clauses.

Mission Technologies

Sales and Service Revenues

Mission Technologies revenues, including intersegment sales, for the three months ended June 30, 2023, increased $45 million, or 8%, from the same period in 2022, primarily due to higher volumes in mission based solutions.

Mission Technologies revenues, including intersegment sales, for the six months ended June 30, 2023, increased $79 million, or 7%, from the same period in 2022, primarily due to higher volumes in mission based solutions.

Segment Operating Income

Mission Technologies segment operating income for the three months ended June 30, 2023, was $9 million, compared to segment operating income of $25 million for the same period in 2022. The decrease was primarily driven by lower equity income from our investment in an unconsolidated ship repair and specialty fabrication joint venture, which was sold in June 2023. The results for the three and six months ended June 30, 2023, include a $6 million loss on the sale of the unconsolidated ship repair and specialty fabrication joint venture.

Mission Technologies segment operating income for the six months ended June 30, 2023, was $26 million, compared to segment operating income of $34 million for the same period in 2022. The decrease was primarily driven by lower equity income from our investment in an unconsolidated ship repair and specialty fabrication joint venture, which was sold in June 2023, and lower performance in fleet sustainment, partially offset by higher equity income from nuclear and environmental joint ventures, higher performance in unmanned systems, and higher volumes in mission based solutions.

Product Sales and Segment Cost of Product Sales

Product sales for the three months ended June 30, 2023, increased $50 million, or 3%, from the same period in 2022, primarily as a result of higher volumes at Newport News in aircraft carrier construction, the Columbia class (SSBN 826) submarine program, and the Virginia class (SSN 774) submarine program, partially offset by lower volumes in aircraft carrier refueling and complex overhaul ("RCOH").

Segment cost of product sales for the three months ended June 30, 2023, increased $91 million, or 6%, compared with the same period in 2022, consistent with higher product sales described above and higher costs at Ingalls.

Product sales for the six months ended June 30, 2023, increased $155 million, or 4%, from the same period in 2022, primarily as a result of higher volumes at Newport News in aircraft carrier construction, the Columbia class (SSBN 826) submarine program, and the Virginia class (SSN 774) submarine program, partially offset by lower volumes at Ingalls in the NSC program and amphibious assault ships.

Segment cost of product sales for the six months ended June 30, 2023, increased $206 million, or 7%, compared with the same period in 2022, consistent with higher product sales described above.

Service Revenues and Segment Cost of Service Revenues

Service revenues for the three months ended June 30, 2023, increased $75 million, or 9%, compared with the same period in 2022, primarily as a result of higher volumes at Mission Technologies in mission based solutions and higher volumes at Newport News in aircraft carrier services.

Segment cost of service revenues for the three months ended June 30, 2023, increased $53 million, or 7%, compared with the same period in 2022, consistent with higher service revenues described above.

25

Service revenues for the six months ended June 30, 2023, increased $68 million, or 4%, compared with the same period in 2022, primarily as a result of higher volumes at Mission Technologies in mission based solutions services.

Segment cost of service revenues for the six months ended June 30, 2023, increased $53 million, or 4%, compared with the same period in 2022, consistent with higher service revenues described above.

OTHER FINANCIAL INFORMATION

Interest Expense

Interest expense for the three months ended June 30, 2023, was $24 million, compared with $26 million for the same period in 2022. Interest expense for the six months ended June 30, 2023, was $48 million, compared with $52 million for the same period in 2022. The decreases in interest expense of $2 million and $4 million for the three and six months ended June 30, 2023, respectively, were driven by a decrease in outstanding long-term debt from the prior year periods.

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 June 30, 2023, the non-operating retirement benefit was $37 million, compared with $67 million for the same period in 2022. For the six months ended June 30, 2023, the non-operating retirement benefit was $74 million, compared with $138 million for the same period in 2022. The decreases in the non-operating retirement benefit of $30 million and $64 million for the three and six months ended June 30, 2023, respectively, were primarily driven by lower 2022 returns on plan assets.

Other, Net

Other, net for the three months ended June 30, 2023, was zero, compared with other, net expense of $10 million for the same period in 2022. Other, net income for the six months ended June 30, 2023, was $9 million, compared with other, net expense of $17 million for the same period in 2022. The increases in other, net of $10 million and $26 million for the three and six months ended June 30, 2023, respectively, were primarily driven by unrealized net gains in investments.

Federal and Foreign Income Taxes

Our effective income tax rates on earnings from operations for the three months ended June 30, 2023 and 2022, were 23.1% and 19.8%, respectively. For the six months ended June 30, 2023 and 2022, our effective income tax rates on earnings from operations were 22.0% and 20.1%, respectively. The higher effective tax rate for each of the three and six months ended June 30, 2023, was primarily attributable to a tax gain associated with the sale of our interest in an unconsolidated ship repair and specialty fabrication joint venture.

For each of the three and six months ended June 30, 2023, our effective tax rate differed from the federal statutory rate primarily as a result of the tax gain associated with the sale of our interest in an unconsolidated ship repair and specialty fabrication joint venture. For the three months ended June 30, 2022, our effective tax rate differed from the federal statutory rate primarily as a result of research and development tax credits. For the six months ended June 30, 2022, our effective tax rate did not differ materially from the federal statutory rate.

BACKLOG

Total backlog as of June 30, 2023, and December 31, 2022, was approximately $46.9 billion and $47.1 billion, respectively. Total backlog includes both funded backlog (firm orders for which funding is contractually obligated by the customer) and unfunded backlog (firm orders for which funding is not currently contractually obligated by the customer). Backlog excludes unexercised contract options and unfunded Indefinite Delivery/Indefinite Quantity orders. For contracts having no stated contract values, backlog includes only the amounts committed by the customer.

26

The following table presents funded and unfunded backlog by segment as of June 30, 2023, and December 31, 2022: 

	June 30, 2023						December 31, 2022
					Total						Total
($ in millions)	Funded		Unfunded		Backlog		Funded		Unfunded		Backlog
Ingalls	$	10,345	$	3,157	$	13,502	$	9,231	$	3,546	$	12,777
Newport News	12,632		16,251		28,883		11,665		17,742		29,407
Mission Technologies	1,466		3,004		4,470		1,317		3,622		4,939
Total backlog	$	24,443	$	22,412	$	46,855	$	22,213	$	24,910	$	47,123

We expect approximately 21% of the $47.1 billion total backlog as of December 31, 2022, to be converted into sales in 2023. U.S. Government orders comprised substantially all of the backlog as of June 30, 2023, and December 31, 2022.

Contract Awards

The value of new contract awards during the six months ended June 30, 2023, was approximately $5.2 billion, including an award modification for the detail design and construction of LPD 32 (unnamed), an award modification for long-lead-time material and advance construction activities on the Columbia class (SSBN 826) submarine program, an award modification to the construction contract for John F. Kennedy (CVN 79), and an award modification for long-lead-time material for additional Block V boats of the Virginia class (SSN 774) submarine program.

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 assist in capital deployment decision making, 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:

	Six Months Ended June 30				2023 vs. 2022
($ in millions)	2023		2022		Dollars
Net earnings	$	259	$	318	$	(59)
Depreciation and amortization	178		178		—
Provision for doubtful accounts	—		(7)		7
Stock-based compensation	18		16		2
Deferred income taxes	(62)		(1)		(61)
Loss (gain) on investments in marketable securities	(12)		26		(38)
Retiree benefits	(36)		(65)		29
Trade working capital increase	(272)		(281)		9
Net cash provided by operating activities	$	73	$	184	$	(111)

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 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 six months ended June 30, 2023 and 2022, as classified on our unaudited condensed consolidated statements of cash flows.

27

Operating Activities

Cash provided by operating activities for the six months ended June 30, 2023, was $73 million, compared with $184 million provided by operating activities for the same period in 2022. The unfavorable change in operating cash flow was primarily due to higher income tax payments.

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 July 1, 2023, and beyond such 12-month period based on our current business plans.

Investing Activities

Cash used in investing activities for the six months ended June 30, 2023, was $70 million, compared with $101 million used in investing activities for the same period in 2022. The change in investing cash was primarily driven by the sale of an unconsolidated ship repair and specialty fabrication joint venture, partially offset by increased investment in one of our unconsolidated nuclear and environmental joint ventures. For 2023, we expect our capital expenditures for maintenance and sustainment to be approximately 1.0% of annual revenues and our discretionary capital expenditures to be approximately 2.0% of annual revenues.

Financing Activities

Cash used in financing activities for the six months ended June 30, 2023, was $157 million, compared with $335 million used in financing activities for the same period in 2022. The change in cash used in financing activities was primarily due to a $170 million decrease in prepayments of our Term Loan.

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 provided by operating activities to free cash flow:

	Six Months Ended June 30				2023 vs. 2022
($ in millions)	2023		2022		Dollars
Net cash provided by operating activities	$	73	$	184	$	(111)
Less capital expenditures:
Capital expenditure additions	(111)		(102)		(9)
Grant proceeds for capital expenditures	3		—		3
Free cash flow	$	(35)	$	82	$	(117)

Free cash flow for the six months ended June 30, 2023, decreased $117 million from the same period in 2022, primarily due to higher income tax payments and increased capital expenditures.

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 June 30, 2023 and 2022, 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.

28

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 June 30, 2023, $14 million in letters of credit were issued but undrawn and $360 million of surety bonds were outstanding. As of June 30, 2023, we had no other significant off-balance sheet arrangements.

32

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 $650 million Term Loan, a $1.5 billion Revolving Credit Facility, and a $1 billion commercial paper program. As of June 30, 2023, we had $195 million outstanding on the Term Loan and no indebtedness outstanding under our Revolving Credit Facility or our commercial paper program. Based on the amounts outstanding under our Term Loan as of June 30, 2023, an increase of 1% in interest rates would increase the interest expense on our debt by approximately $2 million on an annual basis.

Inflation - Macroeconomic factors have contributed, and we expect will continue to contribute, to 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 protection in customer contracts to the extent possible. We include assumptions of anticipated cost growth in the development of our cost of completion estimates, but 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

Disclosure Controls and Procedures

The Company's management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of June 30, 2023. Based on that evaluation, the Company's Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2023, the Company's disclosure controls and procedures were effective to ensure that information required to be disclosed in reports the Company files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) accumulated and communicated to management to allow their timely decisions regarding required disclosure.

to continuation of the performance-based vesting requirements over the three-year performance period (which period ends on December 31, 2024) of the 2022 RPSR Award.

The terms of the RPSRs granted to Mr. Petters in 2021 under the 2012 Plan (the “2021 RPSR Award”) provided that, in the event of Mr. Petters’ retirement from the Company prior to the end of the applicable three-year performance period (which period ends on December 31, 2023), the number of RPSRs that could vest and become earned RPSRs upon achievement of the applicable performance criteria would be prorated based on the number of full months during the applicable three-year performance period that Mr. Petters was actually employed by the Company. As a result, on December 31, 2022, the effective date of Mr. Petters’ retirement from the Company, Mr. Petters’ 2021 RPSR Award was prorated to time vest two-thirds of the 2021 RPSR Award.

Consistent with the Compensation Committee’s intent for the 2021 RPSR Award to match the time-based vesting terms of the 2022 RPSR Award but recognizing that the 2021 RPSR Award was already prorated, on July 31, 2023, the Compensation Committee approved a cash payment from the Company to Mr. Petters, which will be paid following the end of the 2021 RPSR Award performance period in an amount equal to (x) the value of the number of shares of the Company’s common stock that he would have otherwise been entitled to receive under the 2021 RPSR Award without proration of the award, less (y) the value of the number of shares of the Company’s common stock that Mr. Petters actually receives upon settlement of the prorated 2021 RPSR Award.

(c) Adoption or Termination of Trading Arrangements

None.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

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, 2022 (the "2022 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. The effects of this practice only exist 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 $217 million and $209 million as of June 30, 2023, and December 31, 2022, respectively, and are presented within miscellaneous other assets within 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 current portion) as of June 30, 2023, and December 31, 2022, were $2,224 million and $2,703 million, respectively. The estimated fair values of the current portion of the Company's long-term debt were $482 million and $390 million as of June 30, 2023 and December 31, 2022, 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 under the fair value hierarchy.

Debt - In April 2023, the Company amended its existing $1.5 billion credit facility (the "Revolving Credit Facility") and $650 million term loan due August 19, 2024 (the "Term Loan") to change the benchmark interest rate from the London Interbank Offered Rate to the Secured Overnight Financing Rate (“SOFR”). The current interest rate is based on SOFR plus an interest spread based on the Company's credit rating, plus an additional 0.10%. The Company does not expect the transition to the SOFR benchmark to materially impact its financial results. For further information on the Company's debt, see the Company's 2022 Annual Report on Form 10-K.

Goodwill Impairment and Annual Assessment Date Change - During the second quarter of 2023, the Company elected to change the measurement date of its annual goodwill impairment test from November 30 to October 31. The change is not material to the consolidated financial statements as it does not result in the delay, acceleration, or avoidance of an impairment charge, and the test is still performed in the fourth quarter. The Company continues to perform a quarterly assessment for impairment between annual tests for impairment.

Sale of Equity Method Investment - In June 2023, the Company sold its investment in its unconsolidated ship repair and specialty fabrication joint venture, Titan Acquisition Holdings, L.P. ("Titan"). The Company received $61 million in proceeds and recognized an immaterial loss on sale.

Income Tax Disclosure [Abstract]

Income Taxes

INCOME TAXES

The Company's earnings are primarily domestic, and its effective income tax rates on earnings from operations for the three months ended June 30, 2023 and 2022, were 23.1% and 19.8%, respectively. For the six months ended June 30, 2023 and 2022, the Company's effective income tax rates on earnings from operations were 22.0% and 20.1%, respectively. The higher effective tax rate for each of the three and six months ended June 30, 2023, was primarily attributable to a tax gain associated with the sale of the Company's interest in Titan.

For each of the three and six months ended June 30, 2023, the Company's effective tax rate differed from the federal statutory corporate income tax rate primarily as a result of the tax gain associated with the sale of the Company’s interest in Titan. For the three months ended June 30, 2022, the Company's effective tax rate differed from the federal statutory corporate income tax rate primarily as a result of research and development tax credits. For the six months ended June 30, 2022, the Company's effective tax rate did not differ materially from the federal statutory corporate income tax rate of 21%.

The Company's unrecognized tax benefits increased by $2 million and $4 million during the three and six months ended June 30, 2023, respectively. As of June 30, 2023, the estimated amounts of the Company's unrecognized tax benefits, excluding interest and penalties, were liabilities of $94 million. Assuming a sustainment of these tax positions, a reversal of $71 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 and six months ended June 30, 2023, interest resulting from the unrecognized tax benefits noted above increased income tax expense by $1 million and $2 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 unrecognized state 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.

Investigations, Claims, and Litigation

6 Months Ended

Investigations, Claims, And Litigation [Abstract]

Investigations, Claims, And Litigation

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. Pursuant to Financial Accounting Standards Board Accounting Standards Codification 450 Contingencies, the Company has accrued for losses associated with investigations, claims, and litigation when, and to the extent that, loss amounts related to the investigations, claims, and litigation are probable and can be reasonably estimated. The actual losses that might be incurred to resolve such investigations, claims, and litigation may be higher or lower than the amounts accrued. The Company has also provided 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.

False Claims Act Complaint - In 2016, the Company was made aware that it is a defendant in a qui tam False Claims Act lawsuit pending in the U.S. District Court for the Middle District of Florida related to the Company’s purchases of allegedly non-conforming parts from a supplier for use in connection with U.S. Government contracts. In August 2019, the Department of Justice (“DoJ”) declined to intervene in the lawsuit, and the lawsuit was unsealed. The court dismissed the complaint in September 2021, and the plaintiff has appealed the dismissal to the United States Court of Appeals for the 11th Circuit.

Insurance Claims - 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 has 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.

In September 2021, the Company filed a complaint in the Superior Court of Delaware, seeking a judgment against certain insurers for breach of contract and breach of the implied covenant of good faith and fair dealing under three representations and warranties insurance policies purchased in connection with the Company’s acquisition of Hydroid. The policies insure the Company against losses relating to the seller’s breach of certain representations and warranties in the Hydroid acquisition agreement. The coverage limit under the insurance policies is $70 million, and the Company believes it has incurred losses equal to at least that amount as a result of breaches of the acquisition agreement. 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.

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 six months ended June 30, 2023 and 2022, were not material individually or in the aggregate. The Company’s estimate of asbestos-related liabilities is subject to uncertainty because 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 Litigation - The Company and its predecessor-in-interest have been in litigation with the Bolivarian Republic of Venezuela (the "Republic") since 2002 over a contract for the repair, refurbishment, and modernization at Ingalls of two foreign-built frigates. Following an arbitration proceeding between the parties, in February 2018, the arbitral tribunal awarded the Company approximately $151 million on its claims and awarded the Republic approximately $22 million on its counterclaims. The Company is seeking to enforce and execute upon the award in multiple jurisdictions. No assurances can be provided regarding the ultimate resolution of this matter.

The Company is party to various other claims, legal proceedings, and investigations that arise in the ordinary course of business, including U.S. Government investigations 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 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.

COMMITMENTS AND CONTINGENCIESContract 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 cost to complete environmental remediation has been 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 estimated by management. These 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 June 30, 2023, the probable estimable future cost for environmental remediation was 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 June 30, 2023, the Company had $14 million in issued but undrawn letters of credit and $360 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 Contingencies - In 1985, the Company and the U.S. Navy entered into a settlement agreement to resolve disputes associated with billing and allocating to contracts the cost of workers’ compensation self-insurance, among other matters. Consistent with the 1985 settlement agreement, the Company has not recovered cumulative billable costs resulting from the different treatment of workers' compensation costs between CAS and FAS. Under the 1985 settlement agreement, these costs would be recovered in future periods. In December 2020, a U.S. Navy Contracting Officer issued a determination that the 1985 settlement agreement did not comply with CAS and directed the Company to develop and implement a different process to bill and allocate the cost of workers’ compensation self-insurance. The Company believes the 1985 settlement agreement is CAS-compliant and cannot be unilaterally terminated, but the Company is continuing to negotiate a resolution of the matter with the Contracting Officer.

The Company has been in negotiations with a Mission Technologies customer since January 2023 to address issues related to a manufacturing contract. The Company recorded provisions for contract loss in prior periods that were not material to the Company's consolidated financial position, results of operations, or cash flows. The parties have not agreed upon a resolution of the matter, and the Company could incur additional future losses on the contract. The Company can therefore not predict or give assurances regarding the ultimate outcome of this matter.

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 approximately 43,000 employees, approximately 45% are covered by a total of nine collective bargaining agreements and one site stabilization agreement. The Company believes its relationship with its employees is satisfactory.

Basis of Presentation (Policies)

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Principles of Consolidation

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, 2022 (the "2022 Annual Report on Form 10-K").

Fiscal Period Policy

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. The effects of this practice only exist for interim periods within a reporting year.

Accounting Estimates

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

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 $217 million and $209 million as of June 30, 2023, and December 31, 2022, respectively, and are presented within miscellaneous other assets within 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 current portion) as of June 30, 2023, and December 31, 2022, were $2,224 million and $2,703 million, respectively. The estimated fair values of the current portion of the Company's long-term debt were $482 million and $390 million as of June 30, 2023 and December 31, 2022, 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 under the fair value hierarchy.

Debt Policy

Debt - In April 2023, the Company amended its existing $1.5 billion credit facility (the "Revolving Credit Facility") and $650 million term loan due August 19, 2024 (the "Term Loan") to change the benchmark interest rate from the London Interbank Offered Rate to the Secured Overnight Financing Rate (“SOFR”). The current interest rate is based on SOFR plus an interest spread based on the Company's credit rating, plus an additional 0.10%. The Company does not expect the transition to the SOFR benchmark to materially impact its financial results. For further information on the Company's debt, see the Company's 2022 Annual Report on Form 10-K.

Goodwill and Intangible Assets, Policy

Goodwill Impairment and Annual Assessment Date Change - During the second quarter of 2023, the Company elected to change the measurement date of its annual goodwill impairment test from November 30 to October 31. The change is not material to the consolidated financial statements as it does not result in the delay, acceleration, or avoidance of an impairment charge, and the test is still performed in the fourth quarter. The Company continues to perform a quarterly assessment for impairment between annual tests for impairment.

Equity Method Investments

Sale of Equity Method Investment - In June 2023, the Company sold its investment in its unconsolidated ship repair and specialty fabrication joint venture, Titan Acquisition Holdings, L.P. ("Titan"). The Company received $61 million in proceeds and recognized an immaterial loss on sale.
