Ingalls Shipbuilding revenues for the fourth quarter of 2020 were $752 million, an increase of $50 million, or 7.1%, from the same period in 2019, 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. Surface combatant revenues increased due to higher volumes on Jeremiah Denton (DDG 129), Ted Stevens (DDG 128), Sam Nunn (DDG 133), and John F. Lehman (DDG 137), partially offset by lower volumes on the re-delivered USS Fitzgerald (DDG 62) restoration and modernization. Amphibious assault ship revenues increased as a result of higher volumes on Pittsburgh (LPD 31) and Harrisburg (LPD 30), partially offset by lower volume on the delivered USS Tripoli (LHA 7). Revenues on the Legend-class NSC program decreased due to lower volumes on Friedman (NSC 11) and Calhoun (NSC 10), partially offset by higher volume on the delivered Stone (NSC 9).

Ingalls Shipbuilding segment operating income for the fourth quarter was $96 million, an increase of $37 million from the same period last year. Segment operating margin in the quarter was 12.8%, compared to 8.4% in the same period last year. These increases were primarily driven by higher risk retirement across all programs.

For the full year, Ingalls Shipbuilding revenues were $2.7 billion, an increase of $123 million, or 4.8%, from 2019, primarily driven by higher revenues in surface combatants and amphibious assault ships, partially offset by lower revenues in the Legend-class NSC program. Surface combatant revenues increased due to higher volumes on Ted Stevens (DDG 128), Jeremiah Denton (DDG 129), Delbert D. Black (DDG 119), Sam Nunn (DDG 133), George M. Neal (DDG 131), and Thad Cochran (DDG 135), partially offset by lower volumes on USS Fitzgerald (DDG 62) restoration and modernization, Paul Ignatius (DDG 117), Frank E. Petersen Jr. (DDG 121), and Jack H. Lucas (DDG 125). Amphibious assault ship revenues increased as a result of higher volumes on Harrisburg (LPD 30), Pittsburgh (LPD 31), LHA 9 (unnamed), Fort Lauderdale (LPD 28), and Richard M. McCool Jr. (LPD 29), partially offset by lower volumes on Tripoli (LHA 7), LPD life cycle services, and Bougainville (LHA 8). Revenues on the Legend-class NSC program decreased due to lower volumes on Midgett (NSC 8) and Friedman (NSC 11), partially offset by higher volume on Calhoun (NSC 10).

For the full year, Ingalls Shipbuilding segment operating income was $281 million, compared to $235 million in 2019. The increase was primarily driven by higher risk retirement on Delbert D. Black (DDG 119) in connection with its delivery and a capital expenditure contract incentive, as well as higher risk retirement and improved performance on Tripoli (LHA 7) and Richard M. McCool Jr. (LPD 29), partially offset by unfavorable adjustments across programs, including delay and disruption related to COVID-19.

Newport News Shipbuilding revenues for the fourth quarter of 2020 were $1.8 billion, an increase of $351 million, or 25.1%, from the same period in 2019, driven primarily by higher revenues in aircraft carrier construction and refueling and complex overhaul (RCOH), and submarine construction, as well as fleet support services. Aircraft carrier revenues increased primarily as a result of higher volumes on Enterprise (CVN 80) and Doris Miller (CVN 81), and the advance planning contract for the RCOH of USS John C. Stennis (CVN 74), partially offset by lower volumes on John F. Kennedy (CVN 79), USS Gerald R. Ford (CVN 78), and the RCOH of USS George Washington (CVN 73). Submarine revenues increased primarily as a result of higher volumes on Block V boats of the Virginia-class program (VCS) and the Columbia-class program, partially offset by lower volumes on Block III and Block IV boats of the Virginia-class program.

Newport News Shipbuilding segment operating income for the fourth quarter was $128 million, compared to operating income of $137 million for the same period last year. Segment operating margin was 7.3% for the quarter, compared to 9.8% in the same period last year, primarily due to lower risk retirement on the Virginia-class submarine program. Additionally, results in the same period last year benefited from the award of the VCS Block V contract, as well as contract actions related to work on Los Angeles-class submarines.

For the full year, Newport News Shipbuilding revenues were $5.6 billion, an increase of $340 million, or 6.5%, from 2019, primarily driven by higher revenues in aircraft carriers, submarines, and naval nuclear support services. Aircraft carrier revenues increased primarily as a result of higher volumes on Enterprise (CVN 80), the RCOH of USS John C. Stennis (CVN 74), and Doris Miller (CVN 81), partially offset by lower volumes on the RCOH of USS George Washington (CVN 73), John F. Kennedy (CVN 79), and USS Gerald R. Ford (CVN 78). Submarine revenues increased primarily as a result of higher volumes on the Virginia-class submarine program and the Columbia-class submarine program. The higher volume on the Virginia-class submarine program was due to higher volumes on Block V boats, partially offset by lower volumes on Block III and Block IV boats. Naval nuclear support service revenues increased primarily as a result of higher volumes in carrier fleet support services.

For the full year, Newport News Shipbuilding segment operating income was $233 million, a decrease of $177 million from 2019, primarily due to unfavorable cumulative catch-up adjustments in the second quarter on Block IVboats of the Virginia-class submarine program.

Key Newport News Shipbuilding milestones for the quarter:

-- Awarded a $2.2 billion construction contract for six module sections for each of the first two Columbia-class submarines -- Authenticated the keel of Virginia-class submarine Massachusetts (SSN 798) -- John F. Kennedy (CVN 79) is approximately 78% complete -- RCOH of USS George Washington (CVN 73) is approximately 85% complete

Technical Solutions revenues for the fourth quarter of 2020 were $311 million, a decrease of $39 million from the same period in 2019, primarily driven by lower revenue at our oil and gas reporting unit, as well as lower revenue at the San Diego Shipyard due to the conclusion of several repair contracts, partially offset by the acquisition of Hydroid in March 2020.

Technical Solutions segment operating income for the fourth quarter was $18 million, compared to a segment operating loss of $23 million in the fourth quarter of 2019. The increase was primarily driven by a goodwill impairment at our oil and gas reporting unit and a loss on a fleet support services contract, both recorded in the prior year period.

For the full year, Technical Solutions revenues were $1.3 billion, an increase of $31 million, or 2.5%, from 2019, primarily due to the acquisition of Hydroid in 2020, partially offset by lower volume at our San Diego Shipyard due to the conclusion of several repair contracts.

For the full year, Technical Solutions segment operating income was $41 million, compared to an operating loss of $14 million in 2019. The increase was primarily due to a goodwill impairment at our oil and gas reporting unit and a loss on a fleet support services contract in 2019, as well as higher equity income from our nuclear and environmental joint ventures and improved performance in our Defense and Federal Solutions business unit.

Key Technical Solutions milestones for the quarter:

-- Acquired the autonomy business of Spatial Integrated Systems Inc. The acquisition further expands HIIs unmanned systems capabilities with a highly skilled team and proven unmanned surface vessel solutions -- Delivered new REMUS 100 Unmanned Underwater Vehicles to the German Navy. The vehicles will be used to expand the German Navys current fleet of REMUS 100 UUVs used for mine countermeasure operations

2021 Outlook

The financial outlook, expectations and other forward looking statements provided by the company for 2021 and beyond, reflect the company's judgment based on the information available at the time of this release.

The COVID-19 global pandemic has had wide ranging effects on the global health environment and disrupted the global and U.S. economies and financial markets, including impacts to our employees, customers, suppliers, and communities. The pandemic is also impacting our operations, and the full impacts of COVID-19 on our fiscal year 2021 financial results and beyond are uncertain. We believe that the most significant elements of uncertainty are the intensity and duration of the impact on our employees ability to work effectively, disruption in our supply chain, disruption of the U.S. Government's and our other customers' abilities to perform their obligations, and impact on pension assets and other investment performance.

We have incurred and expect to continue incurring costs related to our COVID-19 response, including paid leave, quarantining employees and recurring facility cleaning. While our shipyards and other facilities remainopen and productive, we experienced temporary decreases in workforce attendance, which impacted our operations due to delay and disruption from the lack of availability of critical skills and out-of-sequence work. As of December 31, 2020, workforce attendance has returned to standard rates.

Exhibit B: Non-GAAP Measures Definitions & Reconciliations

We make reference to "segment operating income," "segment operating margin," "shipbuilding revenue," "shipbuilding operating margin," "Technical Solutions EBITDA margin," "adjusted net earnings," "adjusted diluted earnings per share" 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, segment operating margin and shipbuilding 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.

Adjusted net earnings and adjusted diluted earnings per share are not measures recognized under GAAP. They should be considered supplemental to and not a substitute for financial information prepared in accordance with GAAP. We believe these measures are useful to investors because they exclude items that do not reflect our core operating performance. They may not be comparable to similarly titled measures of other companies.

Shipbuilding revenue, shipbuilding operating margin and Technical Solutions EBITDA margin are not measures recognized under GAAP. They should be considered supplemental to and not a substitute for financial information prepared in accordance with GAAP. They 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, analysis of our results as reported under GAAP. 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.

Segment operating income (loss) is defined as operating income (loss) 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 (loss) 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.

Technical Solutions EBITDA margin is defined as Technical Solutions segment operating income before interest expense, income taxes, depreciation, and amortization as a percentage of Technical Solutions revenues.

Adjusted net earnings is defined as net earnings adjusted for the after-tax impact of the FAS/CAS Adjustment.

Adjusted diluted earnings per share is defined as adjusted net earnings divided by the weighted-average diluted common shares outstanding.

Free cash flow is defined as net cash provided by (used in) operating activities less capital expenditures net of related grant proceeds.

FAS/CAS Adjustment is defined as the difference between expenses for pension and other postretirement benefits determined in accordance with GAAP (FAS) and the expenses determined in accordance with U.S. Cost Accounting Standards (CAS).

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 companys 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.
