Third Quarter Results

Third quarter 2025 revenues of $3.2 billion were up 16.1% from the third quarter of 2024, driven by growth at Newport News Shipbuilding, Ingalls Shipbuilding and Mission Technologies.

Segment operating income1 in the third quarter of 2025 was $179 million and segment operating margin1 was 5.6%, compared to $97 million and 3.5%, respectively, in the third quarter of 2024. The increases were driven primarily by more favorable segment results at Newport News Shipbuilding and Ingalls Shipbuilding compared to the prior year period.

Net earnings in the quarter were $145 million, compared to $101 million in the third quarter of 2024. Diluted earnings per share in the quarter was $3.68, compared to $2.56 in the third quarter of 2024.

“We made steady progress on our 2025 operational initiatives in the third quarter," said Chris Kastner, HII’s president and CEO.

Segment operating margin in the third quarter of 2025 was 4.9% compared to 1.1% in the same period last year.

T4Mission Technologies revenues for the third quarter of 2025 were $787 million, an increase of $78 million, or

11.0%, from the same period in 2024. The increases were primarily due to higher volumes in C5ISR; cyber, electronic warfare & space; and live, virtual, and constructive training solutions.

Mission Technologies segment operating income for the third quarter of 2025 was $34 million, an increase of $1 million from the same period in 2024. Segment operating margin in the third quarter of 2025 was 4.3%, compared to 4.7% in the same period last year. Segment operating income was relatively unchanged as changes in contract mix offset the higher volumes described above.

Mission Technologies results included approximately $22 million of amortization of purchased intangible assets in the third quarter of 2025, compared to approximately $25 million in the same period last year.

Mission Technologies EBITDA margin1 in the third quarter of 2025 was 7.8%, compared to 8.9% in the third quarter of 2024.

Cautionary Statement Regarding Forward-Looking Statements and Projections

Statements in this earnings release and in our other filings with the SEC, as well as other statements we may make from time to time, other than statements of historical fact, constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. In some cases, you can identify forward-looking statements by words such as "may," "will," "should," "expects," "intends," "plans," "anticipates," "believes," "estimates," "guidance," "outlook," "predicts," "potential," "continue," and similar words or phrases or the negative of these words or phrases. These statements relate to future events or our future financial performance and involve known and unknown risks, uncertainties, and other factors that may cause our actual results, levels of activity, performance, or achievements to be materially different from any future results, levels of activity, performance, or achievements expressed or implied by these forward-looking statements.

Although we believe the expectations reflected in the forward-looking statements are reasonable when made, we cannot guarantee future results, levels of activity, performance, or achievements. There are a number of important factors that could cause our actual results to differ materially from the results anticipated by our forward-looking statements, which include, but are not limited to: our dependence on the U.S. Government for substantially all of our business; significant delays or reductions in appropriations for our programs and/or changes in customer priorities and requirements (including government budgetary constraints, government shutdowns, shifts in defense spending, and changes in customer short-range and long-range plans);our ability to estimate our future contract costs, including cost increases due to inflation, labor challenges, changes in trade policy, or other factors and our efforts to recover or offset such costs and/or changes in estimated contract costs, and perform our contracts effectively; changes in business practices, procurement processes and government regulations and our ability to comply with such requirements; adverse economic conditions in the United States and globally; our level of indebtedness and ability to service our indebtedness; our ability to deliver our products and services at an affordable life cycle cost and compete within our markets; our ability to attract, retain, and train a qualified workforce; subcontractor and supplier performance and the availability and pricing of raw materials and components; our ability to execute our strategic plan, including with respect to share repurchases, dividends, capital expenditures, and strategic acquisitions; investigations, claims, disputes, enforcement actions, litigation (including criminal, civil, and administrative), and/or other legal proceedings, and improper conduct of employees, agents, subcontractors, suppliers, business partners, or joint ventures in which we participate, including the impact on our reputation or ability to do business; changes in key estimates and assumptions regarding our pension and retiree health care costs; security threats, including cyber security threats, and related disruptions; natural and environmental disasters and political instability; health epidemics, pandemics and similar outbreaks; and other risk factors discussed herein and in our other filings with the SEC.

There may be other risks and uncertainties that we are unable to predict at this time or that we currently do not expect to have a material adverse effect on our business, and we undertake no obligation to update or revise any forward-looking statements. You should not place undue reliance on any forward-looking statements that we may make.

Exhibit B: Non-GAAP Measures Definitions & Reconciliations

This earnings release contains non-GAAP (accounting principles generally accepted in the United States of America) financial measures as defined by SEC Regulation G and indicated by a footnote in the text of this release. Definitions for the non-GAAP measures, and related reconciliations, are provided below. Because not all companies use identical definitions or calculations, our presentation of these measures may not be comparable to similarly titled measures of other companies.

Segment Operating Income and Segment Operating Margin. We internally manage our operations by reference to segment operating income and segment operating margin and use these measures to evaluate our core operating performance. We believe that segment operating income and segment operating margin reflect additional ways of viewing aspects of our operations that, when viewed with our GAAP results, provide a more complete understanding of factors and trends affecting our business. These measures should be considered in addition to, and not as alternatives for, operating income and operating margin or any other performance measure presented in accordance with GAAP.

Segment operating income is defined as operating income for the relevant segment(s) before the Operating FAS/CAS Adjustment and non-current state income taxes.

Segment operating margin is defined as segment operating income as a percentage of sales and service revenues.

Shipbuilding operating margin, Mission Technologies EBITDA and Mission Technologies EBITDA margin. We use shipbuilding operating margin, Mission Technologies EBITDA and Mission Technologies EBITDA margin to evaluate our core operating performance. We believe these measures reflect additional ways of viewing aspects of our operations that, when viewed with our GAAP results, provide a more complete understanding of factors and trends affecting our business. These measures should be considered in addition to, and not as alternatives for, operating income and operating margin or any other performance measure presented in accordance with GAAP.

Shipbuilding operating margin is defined as the combined segment operating income of our Newport News Shipbuilding segment and Ingalls Shipbuilding segment as a percentage of shipbuilding revenue. Shipbuilding revenue is the sum of revenues of our Newport News Shipbuilding segment and Ingalls Shipbuilding segment.

Mission Technologies EBITDA is defined as Mission Technologies segment operating income before interest expense, income taxes, depreciation, and amortization.

Mission Technologies EBITDA margin is defined as Mission Technologies EBITDA as a percentage of Mission Technologies revenues.

Free cash flow. We 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. We believe free cash flow is an important measure that may be useful to investors and other users of our financial statements because it provides insight into our current and period-to-period performance and our ability to generate cash from continuing operations. Free cash flow has limitations as an analytical tool and should not be considered in isolation from, or as a substitute for, net income as a measure of our performance or net cash provided by operating activities as a measure of our liquidity.

Free cash flow is defined as net cash provided by (used in) operating activities less capital expenditures net of related grant proceeds.

In reliance upon Item 10(e)(1)(i)(B) of Regulation S-K, reconciliations of forward-looking GAAP and non-GAAP measures are not provided because of the unreasonable effort associated with providing such reconciliations due to the variability in the occurrence and the amounts of certain components of GAAP and non-GAAP measures. For the same reasons, we are unable to address the significance of the unavailable information, which could be material to future results.
