          LOS ANGELES – Feb. 9, 2011 – Northrop Grumman Corporation (NYSE: NOC) reported that fourth quarter 2010 earnings from continuing operations totaled $376 million, or $1.27 per diluted share, compared with $375 million, or $1.19 per diluted share, in the fourth quarter of 2009. Fourth quarter 2010 results included a previously announced one-time, pre-tax charge of $231 million, or $0.51 per diluted share, principally related to premiums paid to redeem $682 million in debt through the company’s November 2010 tender offer.

          Earnings from continuing operations increased to $2 billion in 2010, or $6.77 per diluted share, from $1.6 billion, or $4.87 per diluted share in 2009. In addition to the fourth quarter charge related to the debt tender offer, 2010 results included a $113 million pre-tax charge related to the consolidation of the company’s Gulf Coast facilities and a $296 million tax benefit related to approval by the Internal Revenue Service (IRS) and the U. S. Congressional Joint Committee on Taxation of the IRS’ examination of tax returns for the years 2004 through 2006. These three items, all of which were previously

announced, resulted in a net increase in 2010 earnings from continuing operations of $0.24 per share.

          Fourth quarter 2010 sales totaled $8.6 billion compared with $8.9 billion in the prior year period. The 2010 fourth quarter had fewer working days than the prior year period. Sales increased 3 percent in 2010 to $34.8 billion from $33.8 billion in 2009. New business awards for the 2010 fourth quarter totaled $9.2 billion, bringing total backlog to $64.2 billion as of Dec. 31, 2010. New business awards totaled $30 billion in 2010.

          Fourth quarter 2010 cash provided by operations increased to $1.4 billion from $931 million in the prior year period. In the 2010 fourth quarter the company’s discretionary pension contributions totaled $440 million, and in the fourth quarter of 2009 the company paid income taxes of $508 million on the sale of its Advisory Services business (TASC). Cash provided by operations totaled $2.5 billion in 2010 compared with $2.1 billion in 2009. Discretionary pension contributions totaled $830 million and $800 million for 2010 and 2009, respectively. Cash provided by operations in 2009 also included $102 million from discontinued operations, as well as the income taxes paid on the sale of TASC.

          “Northrop Grumman had a very good fourth quarter and a strong finish to 2010. Operating income and cash generation exceeded our guidance for the year, demonstrating that across all our businesses, our employees are focusing on performance and building a track record of consistent execution. Northrop Grumman is well positioned to continue creating value for our customers and shareholders,” said Wes Bush, chief executive officer and president.

1 Non-GAAP metric - see definitions and reconciliations at the end of this press release.

          Fourth quarter 2010 operating income increased 25 percent to $788 million from $631 million in the prior year period, and as a percent of sales increased 210 basis points to 9.2 percent from 7.1 percent. For 2010 operating income increased 24 percent to $3.1 billion from $2.5 billion in the prior year period, and as a percent of sales increased 140 basis points to 8.8 percent from 7.4 percent. The improvement for both periods principally reflects higher segment operating income and lower net pension adjustment, partially offset by higher corporate unallocated expenses.

          Fourth quarter 2010 segment operating income increased $143 million, or 19 percent, and 2010 segment operating income increased $397 million, or 14 percent. As a percent of sales, fourth quarter 2010 segment operating income improved 200 basis points to 10.3 percent from 8.3 percent, and 2010 segment operating income improved by 90 basis points to 9.6 percent from 8.7 percent. The improvement in segment operating income and margin rate for both periods primarily reflects improved program performance.

          Net pension adjustment improved by $86 million in the 2010 fourth quarter and $286 million for the full year. Unallocated corporate expenses totaled $95 million in the

2010 fourth quarter and $220 million for the full year, compared with $24 million and $111 million, respectively, for the prior year periods. The increase in corporate unallocated expenses in the 2010 fourth quarter is principally due to additional deferred state taxes and higher other unallowable costs. In 2009 unallocated corporate expenses for the year were reduced by a $64 million pre-tax gain for the settlement of certain litigation matters.

          Federal and foreign income taxes totaled $143 million compared with $196 million in the fourth quarter of 2009. Fourth quarter 2010 included a $15 million credit for the extension of the Research and Development tax credit. The effective tax rate for the 2010 fourth quarter was 27.6 percent compared with 34.3 percent in the 2009 fourth quarter.

          Federal and foreign income taxes totaled $557 million in 2010, including the $296 million benefit from the IRS settlement, compared with $693 million in 2009, which included a net tax benefit of $75 million, primarily for final settlement of the IRS’s examination of the company’s 2001 through 2003 tax returns. The effective tax rate for 2010 was 21.5 percent compared with 30.6 percent in 2009.

          Fourth quarter 2010 diluted earnings per share are based on 296.9 million weighted average shares outstanding compared with 315.5 million in the fourth quarter of 2009. Diluted earnings per share for 2010 are based on 301.1 million weighted average shares outstanding compared with 323.3 million in 2009.

	(1)		Funded backlog represents firm orders for which funding is contractually obligated by the customer.
	(2)		Unfunded backlog represents firm orders for which funding is not currently contractually obligated by the customer. Unfunded backlog excludes unexercised contract options and unfunded Indefinite Delivery Indefinite Quantity (IDIQ) orders.
	(3)		Certain prior period amounts have been reclassified to conform to the 2010 presentation.

New Awards — The estimated value of contract awards included in backlog during the year ended December 31, 2010, was approximately $30 billion.

In the fourth quarter of 2010, a $1.1B reduction in backlog was recorded as a result of the restructure of the National Polar-orbiting Operational Environmental Satellite System (NPOESS). Backlog was also impacted in 2010 by an agreement we reached with the Commonwealth of Virginia related to the VITA contract. The agreement defined minimum revenue amounts for the remaining years under the base contract and extended the contract for three additional years through 2019. We recorded a favorable backlog adjustment of $824 million for the definitization of the base contract revenues for years 2011 through 2016, while the contract extension and 2010 portion of the base contract revenues, totaling $802 million, were recorded as new awards in the period.

Non-GAAP Financial Measures Disclosure: Today’s press release contains non-GAAP (accounting principles generally accepted in the United States of America) financial measures, as defined by SEC (Securities and Exchange Commission) Regulation G and indicated by a footnote in the text of the release. While we believe that these non-GAAP financial measures may be useful in evaluating Northrop Grumman’s financial information, they should be considered as supplemental in nature and not as a substitute for financial information prepared in accordance with GAAP. Definitions are provided for the non-GAAP measures and reconciliations are provided in the body of the release and in attached schedules. References to a “Table” in the definitions below relate to tables in the body of this press release. Other companies may define these measures differently or may utilize different non-GAAP measures.

Cash provided by operations before discretionary pension contributions: Cash provided by operations before the after-tax impact of discretionary pension contributions. Cash provided by operations before discretionary pension contributions has been provided for consistency and comparability of 2010 and 2009 financial performance and is reconciled on Table 2.

Cash provided by continuing operations before discretionary pension contributions: Cash provided by continuing operations before the after-tax impact of discretionary pension contributions. Cash provided by continuing operations before discretionary pension contributions has been provided for consistency and comparability.

Free cash flow: Cash provided by operations less capital expenditures and outsourcing contract and related software costs. We use free cash flow as a key factor in our planning for and consideration of strategic acquisitions, stock repurchases and the payment of dividends. This measure should not be considered in isolation, as a measure of residual cash flow available for discretionary purposes, or as an alternative to operating results presented in accordance with GAAP. Free cash flow is reconciled in Table 2.

Free cash flow from continuing operations before discretionary pension contributions: Cash provided by continuing operations before the after-tax impact of discretionary pension contributions less capital expenditures and outsourcing contract and related software costs. We use free cash flow from continuing operations before discretionary pension contributions as a key factor in our planning for and consideration of strategic acquisitions, stock repurchases and the payment of dividends. This measure should not be considered in isolation, as a measure of residual cash flow available for discretionary purposes, or as an alternative to operating results presented in accordance with GAAP.

Net pension adjustment: Pension expense determined in accordance with GAAP less pension expense allocated to the operating segments under U.S. Government Cost Accounting Standards (CAS). Net pension adjustment is presented in Table 1.

After-tax net pension adjustment per share: The per share impact of the net pension adjustment as defined above, after tax at the statutory rate of 35%, provided for consistency and comparability of 2010 and 2009 financial performance and reconciled on Table 1.

Pension-adjusted diluted EPS from continuing operations: Diluted EPS from continuing operations excluding the after-tax net pension adjustment per share. These per share amounts are provided for consistency and comparability of operating results. Management uses pension-adjusted diluted EPS from continuing operations, as reconciled in Table 1, as an internal measure of financial performance.

Pension-adjusted operating income: Operating income before net pension adjustment as reconciled in Table 1 and used as an internal measure of financial performance.

Pension-adjusted operating income as a % of sales: Pension-adjusted operating income as defined above, divided by sales. Management uses pension-adjusted operating income as a % of sales, as reconciled in Table 1, as an internal measure of financial performance.

Segment operating income (loss): Total earnings from our five segments including allocated pension expense recognized under CAS. Reconciling items to operating income are unallocated corporate expenses, which include management and administration, legal, environmental, certain compensation and retiree benefits, and other expenses; net pension adjustment; and reversal of royalty income included in segment operating income. Management uses segment operating income, as reconciled in Table 5, as an internal measure of financial performance of our individual operating segments.

Segment operating margin % / Segment operating income as a % of sales: Segment operating income as defined above, divided by sales. Management uses segment operating income as a % of sales, as reconciled in Table 5, as an internal measure of financial performance.
