Ingalls Shipbuilding revenues for the fourth quarter of 2022 were $658 million, an increase of $77 million, or 13.3%, from the same period in 2021, primarily driven by higher revenues in surface combatants and amphibious assault ships, partially offset by lower revenues in the *Legend*-class National Security Cutter (NSC) program. Revenues on surface combatants increased due to higher volumes on *Ted Stevens* (DDG 128), *Sam Nunn* (DDG 133), *Telesforo Trinidad* (DDG 139) and *John F. Lehman* (DDG 137), partially offset by lower volume on USS *Frank E. Petersen Jr.* (DDG 121). Revenues on amphibious assault ships increased due to higher volume on *Fallujah* (LHA 9). Revenues on the NSC program decreased due to lower volumes on *Friedman* (NSC 11) and *Calhoun* (NSC 10).

Ingalls Shipbuilding segment operating income<sup>1</sup> for the fourth quarter of 2022 was $50 million, an increase of $2 million from the same period in 2021. Segment operating margin<sup>1</sup> in the fourth quarter of 2022 was 7.6%, compared to 8.3% in the same period last year.

For the full year, Ingalls Shipbuilding revenues were $2.6 billion, an increase of $42 million, or 1.7%, compared to 2021, primarily driven by higher revenues in amphibious assault ships and surface combatants, partially offset by lower revenues in the NSC program. Revenues on amphibious assault ships increased due to higher

volume on *Fallujah* (LHA 9) and *Pittsburgh* (LPD 31), partially offset by lower volume on USS *Fort Lauderdale* (LPD 28) following its delivery. Revenues on surface combatants increased due to higher volume on *Thad Cochran* (DDG 135), *Sam Nunn* (DDG 133), and *Telesforo Trinidad* (DDG 139), partially offset by lower volume on *Jeremiah Denton* (DDG 129) and USS *Frank E. Petersen Jr.* (DDG 121). Revenues on the NSC program decreased due to lower volumes on *Friedman* (NSC 11) and *Calhoun* (NSC 10).

For the full year, Ingalls Shipbuilding segment operating income<sup>1</sup> was $292 million, an increase of $11 million, or 3.9%, from 2021. Full year 2022 segment operating margin<sup>1</sup> was 11.4%, compared to 11.1% in 2021. These increases were primarily due to favorable changes in contract estimates from facilities capital and price adjustment clauses, as well as higher risk retirement on *Harrisburg* (LPD 30) and USS *Fort Lauderdale* (LPD 28), partially offset by receipt of a contract incentive on USS *Jack H. Lucas* (DDG 125) in 2021.

Newport News Shipbuilding revenues for the fourth quarter of 2022 were $1.6 billion, an increase of $45 million, or 2.9%, from the same period in 2021, primarily driven by higher revenues in aircraft carriers and submarines, partially offset by lower revenues in naval nuclear support services. Aircraft carrier revenues increased due to higher volume on the refueling and complex overhaul (RCOH) of USS *John C. Stennis* (CVN 74), as well as the construction of *Doris Miller* (CVN 81), partially offset by lower volume on the RCOH of USS *George Washington* (CVN 73). Submarine revenues increased due to higher volumes on the *Columbia*-class submarine program and Block V boats of the *Virginia*-class submarine (VCS) program, partially offset by lower volumes on Block IV boats of the VCS program. Naval nuclear support service revenues decreased primarily as a result of lower volumes in aircraft carrier fleet support services.

Newport News Shipbuilding segment operating income<sup>1</sup> for the fourth quarter of 2022 was $80 million, a decrease of $15 million from the same period in 2021. Segment operating margin<sup>1</sup> in the fourth quarter of 2022 was 5.1%, compared to 6.2% in the same period last year. The decreases were primarily due to lower risk retirement on the VCS program and the construction of *John F. Kennedy* (CVN 79) compared to the prior year period.

For the full year, Newport News Shipbuilding revenues were $5.9 billion, an increase of $189 million, or 3.3%, compared to 2021, primarily driven by higher revenues in aircraft carriers and submarines, partially offset by lower revenues in naval nuclear support services. Aircraft carrier revenues increased primarily as a result of higher volume on the RCOH of USS *John C. Stennis* (CVN 74) and the construction of *Doris Miller* (CVN 81) and *Enterprise* (CVN 80), partially offset by lower volume on the RCOH of USS *George Washington* (CVN 73) and USS *Gerald R. Ford* (CVN 78). Submarine revenues increased due to higher volumes on the *Columbia*-class

submarine program and Block V boats of the VCS program, partially offset by lower volumes on Block IV boats of the VCS program. Naval nuclear support service revenues decreased primarily as a result of lower volumes in facility maintenance services, partially offset by higher volumes in submarine fleet support services.

For the full year, Newport News Shipbuilding segment operating income<sup>1</sup> was $357 million, an increase of $5 million, or 1.4%, from 2021. The increase was primarily due to favorable changes in contract estimates from facilities capital and price adjustment clauses, as well as contract incentives on the *Columbia-*class submarine program, partially offset by lower risk retirement on the VCS program and the RCOH of USS *George Washington* (CVN 73). Full year 2022 segment operating margin<sup>1</sup> was 6.1%, compared to 6.2% in 2021.

Key Newport News Shipbuilding milestones for the quarter:

Mission Technologies revenues for the fourth quarter of 2022 were $602 million, an increase of $16 million from the same period in 2021. The increase was primarily due to growth in mission based solutions, largely attributable to Alion Science and Technology (Alion).

Mission Technologies segment operating income<sup>1</sup> for the fourth quarter of 2022 was $15 million, compared to $17 million in the fourth quarter of 2021. Segment operating margin<sup>1</sup> in the fourth quarter of 2022 was 2.5%, compared to 2.9% in the same period last year. The decreases in segment operating income<sup>1</sup> and segment operating margin<sup>1</sup> were primarily driven by a non-cash valuation adjustment of approximately $10 million related to an equity method investment that is involved in a pending transaction.

Fourth quarter 2022 results included approximately $24 million of amortization related to the Alion acquisition, compared to approximately $25 million in the same period last year. Mission Technologies EBITDA margin<sup>1</sup> in the fourth quarter of 2022 was 6.6%.

For the full year, Mission Technologies revenues were $2.4 billion, an increase of $911 million, or 61.7%, compared to 2021, primarily due to higher volumes in mission based solutions attributable to the acquisition of Alion in the third quarter of 2021.

For the full year, Mission Technologies segment operating income<sup>1</sup> was $63 million, an increase of $13 million, or 26%, from 2021. The increase in segment operating income<sup>1</sup> was primarily related to the acquisition of Alion in the third quarter of 2022 and higher equity income related to a minority interest in a joint venture, partially offset by higher amortization of purchased intangible assets in 2022 due to the Alion acquisition.

Full year 2022 results included approximately $96 million of amortization of Alion related purchased intangible assets, compared to approximately $33 million in 2021. Mission Technologies EBITDA margin<sup>1</sup> for full year 2022 was 8.2%.

Key Mission Technologies milestones for the quarter:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Awarded U.S. Air Force contract to provide technical analysis and research supporting artificial intelligence, machine learning and cyber modernization priorities

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Awarded U.S. Air Force electronic warfare research and analysis task order

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Unveiled REMUS 620 unmanned underwater vehicle

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Completed integration of Alion

**Cautionary Statement Regarding Forward-Looking Statements**

Statements in this release, other than statements of historical fact, constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. You can generally identify forward-looking statements by words such as "may," "will," "should," "expects," "intends," "plans," "anticipates," "believes," "estimates," "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: changes in government and customer priorities and requirements (including government budgetary constraints, 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, and perform our contracts effectively; changes in procurement processes and government regulations and our ability to comply with such requirements; our ability to deliver our products and services at an affordable life cycle cost and compete within our markets; natural and environmental disasters and political instability; our ability to execute our strategic plan, including with respect to share repurchases, dividends, capital expenditures and strategic acquisitions; adverse economic conditions in the United States and globally; health epidemics, pandemics and similar outbreaks, including the COVID-19 pandemic, and the impacts of vaccination mandates on our workforce; our ability to attract, retain and train a qualified workforce; disruptions impacting global supply, including those attributable to the COVID-19 pandemic and those resulting from the ongoing conflict between Russia and Ukraine; changes in key estimates and assumptions regarding our pension and retiree health care costs; security threats, including cyber security threats, and related disruptions; and other risk factors discussed in our filings with the U.S. Securities and Exchange Commission. 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 any forward-looking statements. You should not place undue reliance on any forward-looking statements that we may make. This release also contains non-GAAP financial measures and includes a GAAP reconciliation of these financial measures.

**Exhibit B: Non-GAAP Measures Definitions & Reconciliations**

We make reference to "segment operating income," "segment operating margin," "shipbuilding revenue," "shipbuilding operating margin," "Mission Technologies EBITDA margin" and "free cash flow."

We internally manage our operations by reference to segment operating income and segment operating margin, which are not recognized measures under GAAP. 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 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 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 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.

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.

Reconciliations of forward-looking GAAP and non-GAAP measures are not provided because we are unable to provide such reconciliations without unreasonable effort due to the uncertainty and inherent difficulty of predicting the future occurrence and financial impact of certain elements 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.

**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.

We present financial measures 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.

Cautionary Statement Regarding Forward-looking Statements 2 Statements in this presentation, other than statements of historical fact, constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. You can generally identify forward-looking statements by words such as "may," "will," "should," "expects," "intends," "plans," "anticipates," "believes," "estimates," "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: changes in government and customer priorities and requirements (including government budgetary constraints, 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, and perform our contracts effectively; changes in procurement processes and government regulations and our ability to comply with such requirements; our ability to deliver our products and services at an affordable life cycle cost and compete within our markets; natural and environmental disasters and political instability; our ability to execute our strategic plan, including with respect to share repurchases, dividends, capital expenditures and strategic acquisitions; adverse economic conditions in the United States and globally; health epidemics, pandemics and similar outbreaks, including the COVID-19 pandemic, and the impacts of vaccination mandates on our workforce; our ability to attract, retain and train a qualified workforce; disruptions impacting global supply, including those attributable to the COVID-19 pandemic and those resulting from the ongoing conflict between Russia and Ukraine; changes in key estimates and assumptions regarding our pension and retiree health care costs; security threats, including cyber security threats, and related disruptions; and other risk factors discussed in our filings with the U.S. Securities and Exchange Commission. 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 any forward-looking statements. You should not place undue reliance on any forward-looking statements that we may make. This release also contains non-GAAP financial measures and includes a GAAP reconciliation of these financial measures. Non-GAAP financial measures should not be construed as being more important than comparable GAAP measures.

Non-GAAP Information 14 We make reference to "segment operating income," "segment operating margin," "shipbuilding revenue," "shipbuilding operating margin," "Mission Technologies EBITDA margin," "Debt/EBITDA" and "free cash flow." We internally manage our operations by reference to segment operating income and segment operating margin, which are not recognized measures under GAAP. 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 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 segment operating income and segment operating margin may not be comparable to similarly titled measures of other companies. Shipbuilding revenue, shipbuilding operating margin and Mission Technologies EBITDA margin are not measures recognized under GAAP. They are measures that we use to evaluate our core operating performance. We believe that shipbuilding revenue, shipbuilding operating margin and Mission Technologies EBITDA 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. When analyzing our operating performance, investors should use shipbuilding revenue, shipbuilding operating margin 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 these measures are used by investors and are a useful indicator to measure our performance. 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. The Debt/EBITDA ratio is not a measure recognized under GAAP. We believe the Debt/EBITDA ratio is useful to management, investors and other users of our financial information in evaluating the total amount of leverage in our capital structure. 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 we are unable to provide such reconciliations without unreasonable effort due to the uncertainty and inherent difficulty of predicting the future occurrence and financial impact of certain elements of GAAP and non-GAAP measures.

Non-GAAP Measures Definitions 15 Debt/EBITDA is defined as gross debt divided by net earnings before interest expense, income taxes, depreciation and amortization. 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. 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. We present financial measures 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.
