Ingalls Shipbuilding revenues for the fourth quarter of 2025 were $889 million, an increase of $153 million, or 20.8%, from the same period in 2024, driven by higher volumes in amphibious assault ships and surface combatants.

Ingalls Shipbuilding segment operating income for the fourth quarter of 2025 was $68 million and segment operating margin was 7.6%, compared to $46 million and 6.3% in the same period in the prior year, respectively. These increases were primarily due to higher volumes and lower unfavorable cumulative catch-up adjustments for amphibious assault ships and surface combatants compared to the prior year period.

Ingalls Shipbuilding 2025 revenues were $3.1 billion, an increase of $311 million, or 11.2%, compared to 2024, primarily driven by higher volumes in surface combatants and amphibious assault ships.

Ingalls Shipbuilding segment operating income in 2025 was $233 million and segment operating margin was 7.6%, compared to $211 million and 7.6% in 2024, respectively. The increase in operating income was primarily due to higher volumes and contract adjustments in surface combatants, partially offset by lower performance in amphibious assault ships.

Key 2025 Ingalls Shipbuilding milestones:

Launched and christened guided missile destroyer Jeremiah Denton (DDG 129)
Christened amphibious transport dock Harrisburg (LPD 30)
Began fabrication of amphibious transport dock Philadelphia (LPD 32)

Newport News Shipbuilding revenues for the fourth quarter of 2025 were $1.9 billion, an increase of $303 million, or 19.1%, from the same period in 2024, primarily driven by higher volumes in submarines and aircraft carriers.

Newport News Shipbuilding segment operating income for the fourth quarter of 2025 was $84 million and segment operating margin was 4.4%, compared to $38 million and 2.4% in the same period in the prior year, respectively. These increases were primarily due to lower unfavorable cumulative catch-up adjustments for Virginia-class submarine construction compared to the prior year period, as well as favorable contract adjustments on the Virginia-class submarine program in the current period, partially offset by contract incentives on the Columbia-class program received in the fourth quarter of 2024.

Newport News Shipbuilding 2025 revenues were $6.5 billion, an increase of $538 million, or 9.0%, compared to 2024, primarily driven by higher volumes in submarines and aircraft carriers.

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
