Ingalls Shipbuilding revenues for the fourth quarter were $641 million, an increase of $61 million, or 10.5 percent, from the same period in 2015, due to higher revenues in surface combatants and the Legend-class National Security Cutter (“NSC”) program, partially offset by lower revenues in amphibious assault ships. Higher surface combatant revenues were primarily due to increased volumes on Lenah H. Sutcliffe Higbee (DDG 123) and Frank E. Petersen Jr. (DDG 121), partially offset by decreased volume on Delbert D. Black (DDG 119) and the delivery of John Finn (DDG 113) in the quarter. Higher NSC program revenues were primarily due to increased volume on Midgett (NSC 8), partially offset by the delivery of USCGC Munro (NSC 6) in the quarter. Lower amphibious assault ships revenues were due to the delivery of USS John P. Murtha (LPD 26) in the second quarter of 2016 and decreased volume on Portland (LPD 27), partially offset by increased volumes on Fort Lauderdale and Bougainville. Ingalls Shipbuilding segment operating income for the fourth quarter was $85 million, an increase of $26 million from the same period last year. Segment operating margin in the quarter was 13.3 percent, compared to 10.2 percent in the same period last year. These increases were primarily due to higher risk retirement and improved performance on the LPD, DDG and NSC programs. For the full year, Ingalls Shipbuilding revenues were $2.4 billion, an increase of $201 million, or 9.2 percent, from 2015, due to higher revenues in surface combatants and amphibious assault ships, partially offset by lower revenues on the NSC program. Higher surface combatants revenues were primarily due to increased volumes on Frank E. Petersen Jr., Lenah H. Sutcliffe Higbee, and planning yard services, partially offset by the delivery of John Finn. Higher amphibious assault ships revenues were primarily due to increased volumes on Fort Lauderdale, Tripoli (LHA 7) and Bougainville, partially offset by lower volume on Portland and the delivery of USS John P. Murtha. Lower NSC program revenues were due to the delivery of USCGC James (NSC 5) in 2015 and the delivery of Munro in 2016, partially offset by higher volume on Midgett. For the full year, Ingalls Shipbuilding segment operating income was $321 million, compared to $379 million in 2015. Segment operating margin was 13.4 percent for 2016, compared to 17.3 percent in 2015. Segment operating income and margin in 2015 included a $136 million favorable impact from an insurance litigation settlement. Adjusting for the insurance litigation settlement, segment operating income in 2016 increased $78 million over 2015, and segment operating margin increased 240 basis points. These increases were primarily due to higher risk retirement on the LPD and DDG programs, partially offset by lower risk retirement on the America class (LHA 6) program. Key Ingalls Shipbuilding milestones for the quarter:

• Awarded a $1.15 billion fixed-priced incentive contract for the detail design and construction of Fort Lauderdale
• Awarded a $486 million fixed-priced incentive contract for the construction of a ninth NSC
• Delivered Munro to the U.S. Coast Guard
• Delivered John Finn to the U.S. Navy
• Launched Kimball (NSC 7)
• Launched Paul Ignatius (DDG 117)

See Exhibit B for reconciliations. Newport News Shipbuilding revenues for the fourth quarter were $1.1 billion, a decrease of $75 million, or 6.3 percent, from the same period in 2015, due to lower revenues in aircraft carriers and submarines. Lower aircraft carriers revenues were primarily due to decreased volumes on the construction contract for Gerald R. Ford (CVN 78) and the execution contract for the RCOH of USS Abraham Lincoln (CVN 72), partially offset by increased volumes on the advance planning contracts for the RCOH of USS George Washington and the construction preparation contract for Enterprise (CVN 80). Lower submarines revenues related to the Virginia class (SSN 774) submarine (“VCS”) program were due to decreased volumes on Block III boats, partially offset by increased volumes on Block IV boats. Newport News Shipbuilding segment operating income for the fourth quarter was $139 million, an increase of $23 million from the same period last year. Segment operating margin was 12.4 percent for the quarter, compared to 9.7 percent in the same period last year. These increases were primarily due to favorable changes in overhead costs and the receipt of a $15 million local government incentive grant, partially offset by lower risk retirement on the VCS program. For the full year, Newport News Shipbuilding revenues were $4.1 billion, a decrease of $209 million, or 4.9 percent, from 2015, due to lower revenues in aircraft carriers. Lower aircraft carrier revenues were primarily due to decreased volumes on the construction contract for Gerald R. Ford and the execution contract for the RCOH of USS Abraham Lincoln, partially offset by increased volumes on the construction contract for John F. Kennedy (CVN 79) and the advance planning contract for the RCOH of USS George Washington. Submarines revenues related to the VCS program were relatively flat in 2016 compared to 2015. Increased volumes on Block IV boats and USS John Warner (SSN 785) post-shakedown availability services were offset by decreased volumes on Block III boats. For the full year, Newport News Shipbuilding segment operating income was $386 million, a decrease of $15 million from 2015. The decrease was primarily due to lower risk retirement on the VCS program, lower volume and lower risk retirement on the execution contract for the RCOH of USS Abraham Lincoln and lower volume on Gerald R. Ford, partially offset by higher volumes on John F. Kennedy (CVN 79) and the RCOH of USS George Washington (CVN 73), favorable changes in overhead costs, and the receipt of a $15 million local government incentive grant. Segment operating margin for 2016 was 9.4 percent, compared to 9.3 percent in 2015.

Technical Solutions revenues for the fourth quarter were $186 million, an increase of $32 million, or 20.8 percent, from the same period in 2015, primarily due to the acquisition of Camber and higher revenues in oil and gas and nuclear and environmental services, partially offset by lower revenues in fleet support. Higher oil and gas revenues were primarily due to increased volume in field services, partially offset by decreased volume in engineering services. Higher nuclear and environmental revenues were primarily due to increased volumes in commercial fabrication services, partially offset by decreased volumes in environmental remediation programs.

Technical Solutions segment operating income for the fourth quarter was $1 million, compared to segment operating loss of $51 million in fourth quarter 2015. Segment operating loss in the fourth quarter of 2015 included a $27 million intangible asset impairment charge and a $16 million goodwill impairment charge. Adjusting for these items, segment operating income in the fourth quarter of 2016 increased $9 million from the same period in 2015. The increase was primarily due to improved performance in oil and gas and fleet support. For the full year, Technical Solutions revenues were $691 million, an increase of $75 million, or 12.2 percent, from 2015, primarily due to increased volumes in nuclear and environmental and fleet support as well as the acquisition of Camber, partially offset by lower volume in oil and gas. For the full year, Technical Solutions segment operating income was $8 million, compared to a segment operating loss of $113 million in 2015. Segment operating loss in 2015 included $75 million of goodwill impairment charges and a $27 million intangible asset impairment charge. Adjusting for these items, segment operating income in 2016 increased $19 million over 2015. The increase was primarily due to improved performance in oil and gas, fleet support and nuclear and environmental.
