(May 1, 2025) - HII (NYSE: HII) today reported results for the first quarter of fiscal 2025. Highlights • First quarter revenues were $2.7 billion • First quarter net earnings were $149 million or $3.79 diluted earnings per share • New contract awards of $2.1 billion, resulting in backlog of $48 billion • Company reaffirms previously issued financial guidance 1 First Quarter Results First quarter 2025 revenues of $2.7 billion were down 2.5% from the first quarter of 2024, driven by lower volume at Newport News Shipbuilding, Ingalls Shipbuilding and Mission Technologies. Operating income in the first quarter of 2025 was $161 million and operating margin was 5.9%, compared to $154 million and 5.5%, respectively, in the first quarter of 2024. The increases were primarily driven by a more favorable operating FAS/CAS adjustment, as well as better segment operating results compared to the prior year. Segment operating income 2 in the first quarter of 2025 was $171 million and segment operating margin 2 was 6.3%, compared to $170 million and 6.1%, respectively, in the first quarter of 2024. The increases were driven primarily by stronger results at Mission Technologies and Newport News Shipbuilding, largely offset by results at Ingalls Shipbuilding. Net earnings in the quarter were $149 million, compared to $153 million in the first quarter of 2024. Diluted earnings per share in the quarter was $3.79, compared to $3.87 in the first quarter of 2024. Net cash used in operating activities in the quarter was $395 million and free cash flow 2 was negative $462 million, compared to net cash used in operating activities of $202 million and free cash flow 1 of negative $274 million in the first quarter of 2024. New contract awards in the first quarter of 2025 were $2.1 billion, bringing total backlog to approximately $48.0 billion as of March 31, 2025. “We are encouraged by the pace of our operational initiatives in 2025. We expect throughput to ramp as we move through the year and, coupled with our cost savings initiatives, we expect steady improvement in support of our operational and financial goals. We are also very supportive of the administration's commitment to expand our nation's shipbuilding capabilities and the maritime industrial base," said Chris Kastner, HII’s president and CEO. 1 The financial outlook, expectations and other forward looking statements provided by the company for 2025 and beyond reflect the company's judgment based on information available at the time of this release. 2 Non-GAAP measures.

Segment operating margin in the first quarter of 2025 was 6.1% compared to 5.7% in the same period last year. The increases were primarily driven by contract incentives on the Virginia -class submarine program and higher volumes on the Columbia -class submarine program, partially offset by lower performance on aircraft carrier construction.

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. 3 Outlook is based on current tax law and assumes the provisions requiring capitalization of R&D expenditures for tax purposes are not deferred or repealed. 4 Outlook is based on current tax law.

When analyzing our operating performance, investors should use segment operating income and segment operating margin in addition to, and not as alternatives for, operating income and operating margin or any other performance measure presented in accordance with GAAP. They are measures that we use 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. We believe these measures are used by investors and are a useful indicator to measure our performance. Because not all companies use identical calculations, our presentation of segment operating income and segment operating margin may not be comparable to similarly titled measures of other companies. Shipbuilding revenue, shipbuilding operating margin, Mission Technologies EBITDA and Mission Technologies EBITDA margin are not measures recognized under GAAP. They are measures that we use to evaluate our core operating performance. When analyzing our operating performance, investors should use shipbuilding revenue, shipbuilding operating margin, Mission Technologies EBITDA and Mission Technologies EBITDA margin in addition to, and not as alternatives for, operating income and operating margin or any other performance measure presented in accordance with GAAP. We believe that shipbuilding revenue, shipbuilding operating margin, Mission Technologies EBITDA and Mission Technologies EBITDA margin reflect an additional way 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. We believe these measures are used by investors and are a useful indicator to measure our performance. Because not all companies use identical calculations, our presentation of shipbuilding revenue, shipbuilding operating margin, Mission Technologies EBITDA and Mission Technologies EBITDA margin may not be comparable to similarly titled measures of other companies. 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 or used by operating activities as a measure of our liquidity. We believe free cash flow is an important 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. 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. 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 revenue is defined as the combined sales and service revenues from our Newport News Shipbuilding segment and Ingalls Shipbuilding segment. 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. HII 4101 Washington Ave. • Newport News, VA 23607 www.HII.com Page 10 of 12 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 is defined as net cash provided by (used in) operating activities less capital expenditures net of related grant proceeds. Operating FAS/CAS Adjustment is defined as the difference between the service cost component of our pension and other postretirement expense determined in accordance with GAAP (FAS) and our pension and other postretirement expense under U.S. Cost Accounting Standards (CAS). Non-current state income taxes are defined as 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 uncertain tax positions 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. Certain of the financial measures we present are adjusted for the Operating FAS/CAS Adjustment and non-current state income taxes to reflect the company’s performance based upon the pension costs and state tax expense charged to our contracts under CAS. We use these adjusted measures as internal measures of operating performance and for performance-based compensation decisions.
