Operating Segment Results

Ingalls Shipbuilding

Ingalls revenues for the fourth quarter increased $46 million, or 6.8 percent from the same period in 2011, driven by an increase in amphibious assault programs. The increase in amphibious assault programs for the fourth quarter was attributable to higher sales on LHA-7 Tripoli, partially offset by lower sales following deliveries of LPD-23 Anchorage in the third quarter of 2012 and LPD-22 USS San Diego in the fourth quarter of 2011. For the full year, Ingalls revenues decreased by $45 million, or 1.6 percent, due to lower sales volume in amphibious assault programs, partially offset by higher sales volume in the Legend-class NSC program. The decrease in amphibious assault program revenues was due to lower sales following the deliveries of LPD-23 Anchorage and LPD-24 Arlington in 2012 and following the delivery of LPD-22 USS San Diego in 2011, partially offset by higher sales volume on LHA-7 Tripoli, LPD-27 (unnamed), LPD-26 John P. Murtha and LPD-25 Somerset. The increase in revenues on the Legend-class NSC program was the result of higher sales volume on the construction of NSC-4 Hamilton and NSC-5 Joshua James and the advance procurement contract on NSC-6 (unnamed), partially offset by lower sales following the delivery of NSC-3 USCGC Stratton in 2011. Surface combatants revenues remained stable for 2012 as higher sales on the DDG-51 Arleigh Burke-class destroyer construction program, driven by higher sales on DDG-114 Ralph Johnson, partially offset by lower sales on DDG-110 USS William P. Lawrence delivered in 2011, and higher sales on the DDG-1000 Zumwalt-class destroyer program, were offset by lower revenues in surface combatants support services.

Ingalls operating income for the fourth quarter was $38 million, an increase of $13 million over the same period in 2011. Ingalls adjusted operating income in the fourth quarter increased by $23 million over the same period in 2011. Ingalls operating margin was 5.3 percent for the quarter, an increase of 304 basis points over the same period in 2011 on an adjusted basis. For the year, Ingalls operating income was $97 million, compared to a loss of $220 million in 2011. Ingalls adjusted operating income in 2012 increased by $27 million, or 38.6 percent, over the prior year. The increase in adjusted operating income was primarily the result of improved overall performance and the receipt of $7 million in resolution of a contract dispute with a private party, partially offset by increased workers’ compensation expense.

Key Ingalls program milestones for the quarter:

• Delivered LPD-24 Arlington, the company’s eighth amphibious transport dock
• Delivered the composite deckhouse for Zumwalt (DDG-1000)
• Christened LHA-6 America, the first in a new class of multi-purpose amphibious ships
• Awarded a $54 million contract for LPD-17 USS San Antonio class life-cycle engineering and support services

Newport News Shipbuilding

Newport News revenues for the fourth quarter increased $44 million, or 4.1 percent, from the same period in 2011. For the full year, Newport News revenues increased by$174 million, or 4.6 percent. For both periods, these increases were primarily driven by higher sales volume in aircraft carrier programs and energy and fleet support services, partially offset by lower sales volume in submarine programs. The increase in aircraft carriers was primarily due to higher revenues on the construction contract for CVN-78 Gerald R. Ford, the advance construction contract for CVN-79 John F. Kennedy, the advance planning contract for the CVN-72 USS Abraham Lincoln RCOH, and the favorable resolution of outstanding contract changes on the CVN-65 USS Enterprise extended dry-docking selected restricted availability (EDSRA), partially offset by lower revenues on the execution contract for the CVN-71 USS Theodore Roosevelt RCOH and an engineering contract for CVN-78 Gerald R. Ford. Energy services revenues were higher due to maintenance services at the Kesselring site. Fleet support revenues increased due primarily to increased maintenance work on in-service aircraft carriers. The decrease in submarine program revenues was the result of lower sales volume on the SSN-774 Virginia-class submarine construction program due to the timing of procurement of production materials.

Newport News operating income for the fourth quarter was $102 million, unchanged from the same period in 2011. Operating margin for the quarter was 9.1 percent, compared to 9.5 percent in the comparable period in 2011. The reduction was driven primarily by finalization of the non-cash workers’ compensation expense in the fourth quarter of 2012. For the year, Newport News operating income was $360 million, or 9.1 percent of revenue, an increase of $18 million over 2011. The increase in operating income was primarily the result of the increased sales volume described above, favorable performance on the execution contract for the CVN-71 USS Theodore Roosevelt RCOH, and the favorable resolution of outstanding contract changes on the CVN-65 USS Enterprise EDSRA, partially offset by higher workers’ compensation expense.

Key Newport News program milestones for the quarter:

• Reached 90 percent structural completion of CVN-78 Gerald R. Ford
• Christened and launched SSN-783 Minnesota, the 10^th Virginia-class submarine
• Awarded a $143 million contract option, under a previously awarded contract, for work on operational and decommissioning U.S. Navy submarines, conversion submarines, special mission submersibles, submarine support facilities and related programs

Additional Information

The company recently identified errors in the valuation of one of its post-retirement benefit plans. The errors, which relate to the valuation methodologies associated with the company’s monthly spending cap under the plan, impacted the projected accumulated post-retirement benefit obligation in every year since 1999. Corrections to previously issued financial results include decreased net earnings for the three months and year ended Dec. 31, 2011, by $2 million and $6 million, respectively, which have been reflected in this press release. The corrections had no impact on segment operating income or cash flow for any period. The cumulative effects of these errors, which management believes are not material to its previously issued consolidated financial statements, will be corrected in the company’s financial statements included in its Annual Report on Form 10-K for the Fiscal Year ended Dec. 31, 2012, that the company will file with the U.S. Securities and Exchange Commission.

Exhibit A: Financial Statements

Exhibit B: Reconciliations

We make reference to “segment operating income,” “segment operating margin,” “adjusted segment operating income,” “adjusted segment operating margin,” “pension-adjusted total operating income,” “pension-adjusted operating margin,” “pension-adjusted net earnings,” and “pension-adjusted diluted earnings per share.”

Segment operating income is defined as operating income before the FAS/CAS Adjustment and deferred state income taxes.

Segment operating margin is segment operating income as a percentage of total sales and service revenues.

Adjusted segment operating income is defined as segment operating income as adjusted for the impact of the goodwill impairment charge in 2011.

Adjusted segment operating margin is defined as adjusted segment operating income as a percentage of segment sales and service revenues.

Pension-adjusted total operating income is defined as total operating income adjusted for the impact of the goodwill impairment charge in 2011 and the FAS/CAS Adjustment.

Pension-adjusted operating margin is defined as pension-adjusted total operating income as a percentage of total sales and service revenues.

Pension-adjusted net earnings is defined as net income adjusted for the impact of the goodwill impairment charge in 2011 and the tax adjusted FAS/CAS Adjustment.

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

Segment operating income and segment operating margin are two of the key metrics we use to evaluate operating performance because they exclude items that do not affect segment performance. We believe adjusted segment operating income, adjusted segment operating margin, pension-adjusted total operating income, pension-adjusted operating margin, pension-adjusted net earnings and pension-adjusted diluted earnings per share are also useful metrics because they exclude non-operating items that we do not consider indicative of our core operating performance. Therefore, we believe it is appropriate to disclose these measures to help investors analyze our operating performance. However, these measures are not measures of financial performance under GAAP and may not be defined or calculated by other companies in the same manner.
