Operating income in the quarter was $213 million and operating margin was 9.7 percent, compared to $231 million and 11.6 percent, respectively, in the fourth quarter of 2017. Diluted earnings per share in the quarter was $4.94, compared to $1.41 in the same period of 2017. 2017 results included one-time expenses related to the early extinguishment of debt, impacts related to the enactment of the U.S. Tax Cuts and Jobs Act of 2017 (the “Tax Act”) and the acceleration of discretionary pension contributions. For the full year, revenues of $8.2 billion increased 9.9 percent over 2017. Operating income in 2018 was $951 million and operating margin was 11.6 percent, compared to $881 million and 11.8 percent, respectively, in 2017. Diluted earnings per share for the full year was $19.09, compared to $10.46 in 2017, which included one-time items described in the preceding paragraph. Cash from operations in 2018 was $914 million and free cash flow¹ was $512 million, compared to $814 million and $453 million, respectively, in 2017. New contract awards in the fourth quarter of 2018 totaled $3.3 billion, bringing total backlog to $23.0 billion as of Dec. 31, 2018. Awards in the fourth quarter of 2018 included a $931 million contract for the construction of the 10^th and 11^th Legend-class National Security Cutters (NSC) for the U.S. Coast Guard and a $883 million contract for the construction of an Arleigh Burke-class destroyer (DDG 131), representing full funding for the third ship of the six ship multi-year contract awarded in the third quarter of 2018. Other major contract awards in 2018 included a $1.4 billion construction contract for amphibious transport dock Richard M. McCool Jr. (LPD 29). “Our 2018 results reflect Huntington Ingalls Industries’ continued execution of our path to 2020 strategy,” said Mike Petters, HII’s president and CEO. “Investing in our facilities, people and capabilities, while winning key contract awards and growing our backlog, positions us well to continue creating long-term value for our shareholders, customers and employees.” ¹ Non-GAAP measure.

Ingalls Shipbuilding revenues for the fourth quarter of 2018 were $699 million, an increase of $61 million, or 9.6 percent, from the same period in 2017, due to higher volumes for amphibious assault ships and surface combatants, partially offset by lower volumes on the NSC program. Higher amphibious assault ship revenues were primarily related to increased volumes on Richard M. McCool Jr. and Bougainville (LHA 8), partially offset by decreased volume on Tripoli (LHA 7). Higher surface combatant revenues were primarily due to repair and restoration work on USS Fitzgerald (DDG 62). Lower NSC program revenues were primarily due to decreased volumes on Midgett (NSC 8) and the delivered USCGC Kimball (NSC 7). Ingalls Shipbuilding segment operating income for the fourth quarter was $84 million, an increase of $9 million from the same period last year. Segment operating margin in the quarter was 12.0 percent, compared to 11.8 percent in the same period last year. These increases were primarily due to higher volumes noted in the preceding paragraph and higher risk retirement for the DDG and NSC programs. For the full year, Ingalls Shipbuilding revenues were $2.6 billion, an increase of $187 million, or 7.7 percent, from 2017, primarily driven by higher revenues in amphibious assault ships, partially offset by lower revenues in surface combatants and the NSC program. Amphibious assault ships revenues increased as a result of higher volumes on Richard M. McCool Jr., Bougainville and Fort Lauderdale (LPD 28), partially offset by lower volumes on the delivered USS Portland (LPD 27) and Tripoli. Surface combatants revenues decreased due to lower volumes on the delivered USS Ralph Johnson (DDG 114), Lenah H. Sutcliffe Higbee (DDG 123), Paul Ignatius (DDG 117), and the delivered USS John Finn (DDG 113), partially offset by higher volumes on USS Fitzgerald (DDG 62) repair and restoration, Jack H. Lucas (DDG 125), and Ted Stevens (DDG 128). Revenues on the NSC program decreased due to lower volumes on the delivered USCGC Kimball (NSC 7) and Midgett (NSC 8), as well as lower risk retirement across the NSC program, partially offset by higher volumes on Stone (NSC 9) and NSC 10 (unnamed). For the full year, Ingalls Shipbuilding segment operating income was $313 million, compared to $313 million in 2017. Segment operating margin was 12.0 percent for 2018, compared to 12.9 percent in 2017. The decrease in margin was primarily due to lower risk retirement on Tripoli and the NSC program, partially offset by recoveries related to a settlement agreement, higher risk retirement on the DDG program, and the higher volumes described above. Key Ingalls Shipbuilding milestones for the quarter:

Awarded $931 million contract for the construction of the 10^th and 11^th U.S. Coast Guard National Security Cutters
Awarded $883 million contract for the construction of an Arleigh Burke-class destroyer (DDG 131)
Christened guided missile destroyer Frank E. Petersen Jr.

Newport News Shipbuilding revenues for the fourth quarter of 2018 were $1.3 billion, an increase of $139 million, or 12.2 percent, from the same period in 2017, due to higher revenues in aircraft carriers and naval nuclear support services, partially offset by lower revenues in submarines. Higher aircraft carrier revenues were primarily related to increased volumes on the advance planning contract for Enterprise (CVN 80), the construction contract for the delivered USS Gerald R. Ford (CVN 78), the advance planning contract for the refueling and complex overhaul (RCOH) of USS John C. Stennis (CVN 74), and the execution contract for the RCOH of USS George Washington (CVN 73), partially offset by decreased volumes on the decommissioned Enterprise (CVN 65). Higher naval nuclear support services revenues were primarily due to increased volumes in submarine support services. Lower submarine revenues related to the Virginia-class submarine (VCS) program were due to decreased volumes on Block III boats. Newport News Shipbuilding segment operating income for the fourth quarter was $57 million, a decrease of $49 million from the same period last year. Segment operating margin was 4.5 percent for the quarter, compared to 9.3 percent in the same period last year. These decreases were primarily due to lower performance in the VCS program, primarily Delaware (SSN 791) and Montana (SSN 794), as well as higher risk retirement on the RCOH program in the fourth quarter of 2017. For the full year, Newport News Shipbuilding revenues were $4.7 billion, an increase of $558 million, or 13.4 percent, from 2017, due to higher revenues in aircraft carriers and naval nuclear support services, partially offset by lower revenues in submarines. Aircraft carriers revenues increased primarily as a result of higher volumes on the execution contract for the RCOH of USS George Washington and the advance planning contract for Enterprise (CVN 80), partially offset by lower volumes on the inactivation of the decommissioned Enterprise (CVN 65) and the execution contract for the RCOH of the redelivered USS Abraham Lincoln (CVN 72). Naval nuclear support services revenues increased primarily as a result of higher volumes in submarine support and facility maintenance services. Submarines revenues related to the VCS program decreased due to lower volumes and performance on Block III boats, partially offset by higher volumes on Block IV and Block V boats. For the full year, Newport News Shipbuilding segment operating income was $318 million, a decrease of $36 million from 2017. Segment operating margin for 2018 was 6.7 percent, compared to 8.5 percent in 2017. These decreases were primarily due to lower performance in the VCS program, the resolution in 2017 of outstanding contract changes on the inactivation of the decommissioned Enterprise (CVN 65) and the RCOH of USS Abraham Lincoln, as well as one-time employee bonus payments in 2018 related to the Tax Act, partially offset by favorable changes in workers’ compensation expense and the increased volumes described above. Key Newport News Shipbuilding milestones for the quarter:

Awarded $197 million modification to a previously awarded contract for long-lead time material and advanced construction activities for the first Columbia-class ballistic missile submarine
Christened and launched the Virginia-class submarine Delaware

Technical Solutions revenues for the fourth quarter of 2018 were $267 million, an increase of $25 million, or 10.3 percent, from the same period in 2017, primarily due to higher revenues in oil and gas services and mission driven innovative solutions, partially offset by lower volumes in fleet support.

Technical Solutions segment operating income for the fourth quarter was $7 million, compared to $8 million in fourth quarter 2017. The decrease was driven primarily by fleet support performance, partially offset by growth in oil and gas services. For the full year, Technical Solutions revenues were $988 million, an increase of $36 million, or 3.8 percent, from 2017, primarily due to higher revenues in oil and gas services and mission driven innovative solutions, partially offset by lower nuclear and environmental revenues and fleet support revenues. For the full year, Technical Solutions segment operating income was $32 million, compared to $21 million in 2017. The increase was primarily due to an allowance for accounts receivable in 2017 on a nuclear and environmental commercial contract and higher income from operating investments at our nuclear and environmental joint ventures in 2018, partially offset by one-time employee bonus payments in 2018 related to the Tax Act and lower performance in fleet support services.

Exhibit B: Non-GAAP Measures Definitions & Reconciliations We make reference to “segment operating income,” “segment operating 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 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. 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. 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 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. Adjusted net earnings is defined as net earnings adjusted for the after-tax impact of the loss on early extinguishment of debt in fourth quarter 2017 and for tax reform. 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 for these items included in segment operating income 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 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.
