Record first quarter revenues of $2.7 billion, up 3.8% compared to first quarter 2022

Company reaffirms FY23 guidance expectations¹

NEWPORT NEWS, Va., May 04, 2023 (GLOBE NEWSWIRE) -- HII (NYSE:HII) reported first quarter 2023 revenues of $2.7 billion, up 3.8% from the first quarter of 2022, driven by growth at Newport News Shipbuilding and Mission Technologies.

Operating income in the first quarter of 2023 was $141 million and operating margin was 5.3%, compared to $138 million and 5.4%, respectively, in the first quarter of 2022. The increase in operating income was primarily driven by favorable changes to the operating FAS/CAS adjustment and non-current state income taxes compared to the prior year, partially offset by lower segment operating income².

Segment operating income² in the first quarter of 2023 was $156 million and segment operating margin² was 5.8%, compared to $176 million and 6.8%, respectively, in the first quarter of 2022. The decrease in segment operating income² was driven primarily by lower risk retirement at Ingalls Shipbuilding following the delivery of USS Fort Lauderdale (LPD 28) in the first quarter of 2022.

Net earnings in the quarter were $129 million, compared to $140 million in the first quarter of 2022. Diluted earnings per share in the quarter was $3.23, compared to $3.50 in the first quarter of 2022. The decrease in diluted earnings per share was driven by a less favorable non-operating retirement benefit in the current quarter.

Net cash used in operating activities in the quarter was $9 million and free cash flow²was negative $49 million, compared to cash used in operating activities of $83 million and negative free cash flow² of $126 million in the first quarter of 2022.

New contract awards in the first quarter of 2023 were approximately $2.6 billion, bringing total backlog to approximately $47.0 billion as of March 31, 2023.

"First quarter results reflect a good start to the year, as we stay on course executing our nearly $50 billion of backlog and growing our Mission Technologies business in markets that support our customers," said Chris Kastner, HII's president and CEO. "Our priority continues to be a focus on the fundamentals in shipbuilding and delivery of critically needed assets to the fleet. Our shipbuilding milestones for 2023 and 2024 remain on track as we work closely with the Navy to optimize the delivery schedule for aircraft carrier John F. Kennedy."

Ingalls Shipbuilding revenues for the first quarter of 2023 were $577 million, a decrease of $54 million, or 8.6%, from the same period in 2022, primarily driven by lower revenues in amphibious assault ships and the Legend-class National Security Cutter (NSC) program, partially offset by higher revenues in surface combatants. Revenues on amphibious assault ships decreased due to lower volumes on USS Fort Lauderdale (LPD 28), Bougainville (LHA 8), amphibious ship planning yard services contract and Richard M. McCool Jr. (LPD 29), partially offset by higher volumes on Fallujah (LHA 9) and LPD 32 (unnamed). Revenues on the NSC program decreased due to lower volume on Friedman (NSC 11). Revenues on surface combatants increased due to higher volumes on George M. Neal (DDG 131), Jeremiah Denton (DDG 129), John F. Lehman (DDG 137) and Ted Stevens (DDG 128), partially offset by lower volumes on Lenah Sutcliffe Higbee (DDG 123) and USS Jack H. Lucas (DDG 125).

Ingalls Shipbuilding segment operating income¹ for the first quarter of 2023 was $55 million, a decrease of $31 million from the same period in 2022. Segment operating margin¹in the first quarter of 2023 was 9.5%, compared to 13.6% in the same period last year. The decrease was primarily driven by lower risk retirement on USS Fort Lauderdale (LPD 28), which was delivered in the first quarter of 2022, and Bougainville (LHA 8).

Key Ingalls Shipbuilding milestones for the quarter:

Awarded $1.3 billion detail design & construction contract for LPD 32 (unnamed)
Awarded $10.5 million modernization planning contract for Zumwalt-class guided missile destroyers,

USS Zumwalt (DDG 1000) and USS Michael Monsoor (DDG 1001)

Newport News Shipbuilding revenues for the first quarter of 2023 were $1.5 billion, an increase of $116 million, or 8.3%, from the same period in 2022, 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 volumes on the refueling and complex overhaul (RCOH) of USS John C. Stennis (CVN 74) and the construction of Doris Miller (CVN 81), Enterprise (CVN 80) and John F. Kennedy (CVN 79), partially offset by lower volume on the RCOH of USS George Washington (CVN 73). Submarine revenues increased due to higher volumes on the Block V boats of the Virginia-class submarine (VCS) program and the Columbia-class submarine program, partially offset by lower volumes on Block IV boats of the VCS program. Naval nuclear support services revenue decreased primarily as a result of lower volumes in carrier fleet support services.

Newport News Shipbuilding segment operating income¹ for the first quarter of 2023 was $84 million, an increase of $3 million from the same period in 2022. Segment operating margin¹ in the first quarter of 2023 was 5.6%, compared to 5.8% in the same period last year. The increase in segment operating income¹was primarily due to higher sales volume across all programs, partially offset by unfavorable risk retirement on the Enterprise (CVN 80).

Key Newport News Shipbuilding milestones for the quarter:

Broke ground on a new multi-class submarine production facility to support the construction and delivery of Columbia-class and Virginia-class submarines
Reached approximate 99% completion of the RCOH of USS George Washington (CVN 73)
Reached approximate 89% completion of John F. Kennedy (CVN 79) based on current scope and schedule

Mission Technologies revenues for the first quarter of 2023 were $624 million, an increase of $34 million, or 5.8%, from the same period in 2022. The increase was primarily due to higher volumes in Mission Based Solutions, which includes our C5ISR, Cyber and Electronic Warfare and Live, Virtual, and Constructive Solutions businesses, as well as higher volumes in Fleet Sustainment.

Mission Technologies segment operating income¹ for the first quarter of 2023 was $17 million, compared to $9 million in the first quarter of 2022. Segment operating margin¹ in the first quarter of 2023 was 2.7%, compared to 1.5% in the same period last year. The increases were primarily driven by improved performance in Mission Based Solutions and Unmanned Systems and higher equity income from Nuclear and Environmental joint ventures, partially offset by lower performance in Fleet Sustainment.

Mission Technologies results included approximately $27 million of amortization of purchased intangible assets in the first quarter of 2023, compared to approximately $30 million in the same period last year. Mission Technologies EBITDA margin¹in the first quarter of 2023 was 8.0%.

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," "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, 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.

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 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.
