HII Reports Third Quarter 2022 Results

•Revenues were $2.6 billion in the quarter

•Net earnings of $138 million or $3.44 diluted earnings per share

•Narrows FY22 revenue guidance ranges

•Reaffirms shipbuilding operating margin1 guidance, revises Mission Technologies operating margin guidance

•Increases FY22 free cash flow1 guidance and updates for current R&D tax treatment

NEWPORT NEWS, Va. (November 3, 2022) - HII (NYSE:HII) reported third quarter 2022 revenues of $2.6 billion, up 12.3% from the third quarter of 2021, primarily driven by revenue attributable to the acquisition of Alion Science and Technology (Alion) in the third quarter of 2021, as well as revenue growth at Newport News Shipbuilding.

Operating income in the third quarter of 2022 was $131 million and operating margin was 5.0%, compared to $118 million and 5.0%, respectively, in the third quarter of 2021. The increase in operating income was primarily driven by favorable changes to non-current state income taxes and operating FAS/CAS adjustment compared to the prior year, as well as higher segment operating income1.

Segment operating income1 in the third quarter of 2022 was $166 million and segment operating margin1 was 6.3%, compared to $163 million and 7.0%, respectively, in the third quarter of 2021. The increase in segment operating income1 was driven primarily by improved results at Newport News Shipbuilding.

Net earnings in the quarter were $138 million, compared to $147 million in the third quarter of 2021. Diluted earnings per share in the quarter was $3.44, compared to $3.65 in the third quarter of 2021. The decrease in diluted earnings per share was driven by a significant tax benefit in the prior year, as well as negative impacts related to equity investments in the current quarter, partially offset by a more favorable non-operating retirement benefit in the current quarter.

Net cash used in operating activities in the quarter was $19 million and free cash flow1 was negative $96 million, compared to cash provided by operating activities of $350 million and free cash flow1 of $277 million in the third quarter of 2021.

New contract awards in the third quarter of 2022 were approximately $2.1 billion, bringing total backlog to approximately $46.7 billion as of September 30, 2022.

“Notwithstanding a continued challenging economic environment, we remain focused on consistent shipbuilding program execution and capturing contract awards at our Mission Technologies division,” said Chris Kastner, HII’s president and CEO. "We are confident in the positioning of the business for long-term value creation given the tremendous volume of shipbuilding work we have secured in backlog and a Mission Technologies division that is poised for growth in markets of critical importance to our customers."

Ingalls Shipbuilding revenues for the third quarter of 2022 were $623 million, a decrease of $5 million, or 0.8%, from the same period in 2021, primarily driven by lower revenues in the Legend-class National Security Cutter (NSC) program and amphibious assault ships, partially offset by higher revenues in surface combatants. Revenues on the NSC program decreased due to lower volumes on Friedman (NSC 11) and Calhoun (NSC 10). Revenues on amphibious assault ships decreased due to lower volumes on USS Fort Lauderdale (LPD 28), partially offset by higher volumes on LHA 9 (unnamed). Revenues on surface combatants increased due to higher volumes on Thad Cochran (DDG 135) and Telesforo Trinidad (DDG 139), partially offset by lower volumes on Frank E. Petersen Jr. (DDG 121), Jeremiah Denton (DDG 129) and Ted Stevens (DDG 128).

Ingalls Shipbuilding segment operating income1 for the third quarter of 2022 was $50 million, a decrease of $12 million from the same period in 2021. Segment operating margin1 in the third quarter of 2022 was 8.0%, compared to 9.9% in the same period last year. The decreases were primarily driven by lower risk retirement on Ted Stevens (DDG 128) and USS Delbert D. Black (DDG 119) related to a capital expenditure incentive received in the third quarter of 2021, partially offset by higher risk retirement on USS Portland (LPD 27).

Key Ingalls Shipbuilding milestones for the quarter:

•Awarded a design engineering contract for the next-generation guided-missile destroyer - DDG(X)

•Authenticated the keel of guided-missile destroyer Jeremiah Denton (DDG 129)

•Awarded a contract to begin combat systems availability for the Zumwalt-class destroyer, Lyndon B. Johnson (DDG 1002)

•Began fabrication of amphibious transport dock Pittsburgh (LPD 31)

Newport News Shipbuilding revenues for the third quarter of 2022 were $1.4 billion, an increase of $91 million, or 6.7%, from the same period in 2021, primarily driven by higher revenues in naval nuclear support services, submarines and aircraft carriers. Naval nuclear support services revenues increased primarily as a result of higher volumes in submarine and carrier fleet support services. 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 submarine services and Block IV boats of the VCS program. Aircraft carrier revenues increased primarily as a result of higher volumes on the refueling and complex overhaul (RCOH) of USS John C. Stennis (CVN 74), partially offset by lower volumes on the RCOH of USS George Washington (CVN 73).

Newport News Shipbuilding segment operating income1 for the third quarter of 2022 was $102 million, an increase of $14 million from the same period in 2021. Segment operating margin1 in the third quarter of 2022 was 7.1%, compared to 6.5% in the same period last year. The increases were primarily due to contract incentives on the Columbia-class submarine program, partially offset by lower risk retirement on the VCS program.

Key Newport News Shipbuilding milestones for the quarter:

•Achieved pressure hull complete on Virginia-class submarine Massachusetts (SSN 798)

•Celebrated the ceremonial keel laying of aircraft carrier Enterprise (CVN 80)

•Reached approximate 98% completion of the RCOH of USS George Washington (CVN 73)

•Reached approximate 87% completion of John F. Kennedy (CVN 79)

All values are in US Dollars.

Mission Technologies revenues for the third quarter of 2022 were $595 million, an increase of $201 million from the same period in 2021. The increase was primarily due to higher volumes in Defense & Federal Solutions (DFS) attributable to the acquisition of Alion, which was completed on August 19, 2021.

Mission Technologies segment operating income1 for the third quarter of 2022 was $14 million, compared to $13 million in the third quarter of 2021. Segment operating margin1 in the third quarter of 2022 was 2.4%, compared to 3.3% in the same period last year. The increase in segment operating income1 was primarily driven by the acquisition of Alion in the third quarter of 2021 and higher equity income, partially offset by higher amortization of purchased intangible assets in 2022.

The decrease in segment operating margin1 was primarily driven by approximately $24 million of amortization of Alion related purchased intangible assets in the third quarter of 2022, compared to approximately $8 million in the same period last year. Mission Technologies EBITDA margin1 in the third quarter of 2022 was 8.4%.

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 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. 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.

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