FALLS CHURCH, Va. – Oct. 26, 2011 – Northrop Grumman Corporation (NYSE: NOC) reported that third quarter 2011 earnings from continuing operations increased 16 percent to $520 million, or $1.86 per diluted share, from $448 million, or $1.51 per diluted share, in the third quarter of 2010. For the nine months ended Sept. 30, 2011, the company repurchased 28.4 million shares of its common stock for $1.6 billion, and $2.4 billion remained under its current share repurchase authorization.

“Superior operating performance in our businesses drove higher operating income, earnings, cash and a strong book-to-bill ratio for the quarter. Based on year-to-date operating results and effective cash deployment, we are again raising our 2011 EPS guidance. The combination of performance and share repurchases continues to produce strong earnings per share growth despite top line pressures,” said Wes Bush, chairman, chief executive officer and president.

Third quarter 2011 operating income increased $102 million or 14 percent, and as a percent of sales increased 230 basis points to 12.5 percent. The improvement over the prior year reflects improved segment operating income and a $101 million increase in net pension income, which more than offset higher unallocated corporate expenses during the period. Despite lower sales, third quarter 2011 segment operating income increased 2 percent to $777 million and as a percent of sales improved 110 basis points to 11.8 percent.

Third quarter 2011 net earnings totaled $520 million, or $1.86 per diluted share, compared with $497 million, or $1.67 per diluted share, in the third quarter of 2010.

Third quarter 2011 diluted earnings per share are based on 279.3 million weighted average shares outstanding compared with 297.6 million shares in the third quarter of 2010. Results for both periods reflect the spin-off of Huntington Ingalls Industries, Inc. (HII), the company’s former Shipbuilding business, effective March 31, 2011; Shipbuilding financial results are reported as discontinued operations.

Cash provided by continuing operations before discretionary pension contributions through Sept. 30, 2011, increased to $1.4 billion from $1.2 billion in the prior year, and free cash flow from continuing operations before discretionary pension contributions through Sept. 30, 2011, increased to $1.1 billion from $929 million in the prior year.

2011 Guidance Updated

Based on year-to-date results, the company now expects 2011 earnings per share from continuing operations of $6.95 to $7.05 per diluted share. The increase in expected 2011 earnings per share reflects higher expected segment operating margin rate and total operating margin rate, and lower weighted average shares outstanding.

Other, net for the 2011 third quarter was an expense of $13 million compared with income of $13 million in the prior year period, due to the write-down of an equity investment and higher non-qualified employee benefit costs.

Federal and foreign income tax expense totaled $235 million in the third quarter of 2011 compared with $224 million in the prior year period. The effective tax rate for the 2011 third quarter was 31.1 percent compared with 33.3 percent for the third quarter of 2010. In the 2011 third quarter the company recognized net tax benefits of $14 million related to the filing of its 2010 tax return.

Aerospace Systems ($ millions)

	Third Quarter						Nine Months
	2011		2010		% Change		2011		2010		% Change
Sales	$	2,572	$	2,706		(5.0%)	$	7,900	$	8,244		(4.2%)
Operating income		304		303		0.3%		936		934		0.2%
as a % of sales		11.8%		11.2%				11.8%		11.3%

Aerospace Systems third quarter 2011 sales declined 5 percent due to lower volume for space systems and manned aircraft programs. Lower volume for space systems is primarily due to reduced funding for weather satellite programs and the James Webb Space Telescope program, as well as lower volume for several other space programs. Lower manned aircraft sales include lower volume for the F-35 program. Lower F-35 volume reflects the transition to use of units-of-delivery revenue recognition method beginning with low rate initial production lot 5.

Aerospace Systems third quarter 2011 operating income was comparable to the prior year period and as a percent of sales increased to 11.8 percent from 11.2 percent due to improved program performance and lower amortization of purchased intangibles, which were partially offset by lower volume and an unfavorable performance adjustment for a space program.

Electronic Systems ($ millions)

	Third Quarter						Nine Months
	2011		2010		% Change		2011		2010		% Change
Sales	$	1,905	$	1,874		1.7%	$	5,504	$	5,740		(4.1%)

as a % of sales		15.4%		13.9%				14.8%		13.1%

Electronic Systems third quarter 2011 sales increased 2 percent principally due to higher volume for intelligence, surveillance and reconnaissance systems, targeting systems, and naval marine systems programs. Higher volume for these programs was partially offset by lower volume for land and self protection systems programs, including lower deliveries of Vehicular Intercommunication Systems (VIS).

Electronic Systems third quarter 2011 operating income increased 12 percent, and as a percent of sales increased to 15.4 percent from 13.9 percent. Higher operating income and margin rate reflect higher volume as well as positive performance adjustments for a space program and an international radar program. Positive adjustments for these programs were partially offset by a provision for a dispute on the Flats Sequencing System domestic postal automation program.

as a % of sales		9.6%		8.9%				9.5%		9.2%

Information Systems third quarter 2011 sales declined 8 percent due to lower volume for defense systems and civil systems programs, partially offset by higher volume for intelligence systems programs. For defense systems, reduced funding on existing programs and program completions reduced third quarter 2011 sales. Civil systems volume was reduced by the sale of the County of San Diego outsourcing contract, which contributed sales of $32 million in the third quarter of 2010.

Information Systems third quarter 2011 operating income declined 2 percent and as a percent of sales increased to 9.6 percent compared with 8.9 percent in the prior year period. The decline in operating income principally reflects lower volume and a reserve for overhead rates resulting from the decline in sales. The improvement in margin rate principally reflects better performance for civil systems programs, including the effect of the sale of the County of San Diego outsourcing contract.

as a % of Sales		8.1%		6.4%				7.9%		6.4%

Technical Services third quarter 2011 sales declined 22 percent primarily due to the change in the NSTec joint venture. As previously announced, effective Jan. 1, 2011, the company reduced its participation in the NSTec joint venture, and as a result did not record any sales for the joint venture in the 2011 third quarter. NSTec sales totaled $163 million in the third quarter of 2010.

Technical Services third quarter 2011 operating income was comparable to the prior year, and as a percent of sales increased to 8.1 percent from 6.4 percent, principally due to the change in revenue consolidation for the NSTec joint venture.

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 our 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. 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.

Adjusted diluted EPS from continuing operations: Diluted EPS from continuing operations excluding the after-tax net pension adjustment per share, as defined below, and the per share tax benefit recorded in the 2010 second quarter. These per share amounts are provided for consistency and comparability of operating results. Management uses adjusted diluted EPS from continuing operations, as reconciled in Table 1, as an internal measure of financial performance.

Cash provided by continuing operations before discretionary pension contributions: Cash provided by 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 of 2011 and 2010 financial performance and is reconciled in Table 2.

Free cash flow from continuing operations: Cash provided by continuing operations less capital expenditures and outsourcing contract and related software costs. We use free cash flow from continuing operations 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 from continuing operations is reconciled in Table 2.

Free cash flow from continuing operations before discretionary pension contributions: Free cash flow from continuing operations before the after-tax impact of discretionary pension contributions. 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. Free cash flow from continuing operations before discretionary pension contributions, also referred to as pension-adjusted free cash flow from continuing operations, is reconciled in Table 2.

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 2011 and 2010 financial performance as presented in Table 1.

Pension-adjusted operating income: Operating income before net pension adjustment as reconciled in Table 1. Management uses pension-adjusted operating income 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: Total earnings from our four 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 4, 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 4, as an internal measure of financial performance.
