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.

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.

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

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.
