FALLS CHURCH, Va. – Jan. 30, 2013 – Northrop Grumman Corporation (NYSE: NOC) reported fourth quarter 2012 earnings from continuing operations of $533 million, or $2.14 per diluted share, compared with $550 million, or $2.09 per diluted share, in the fourth quarter of 2011. The increase in earnings per share was principally due to a $102 million increase in segment operating income and a lower share count, partially offset by a $67 milliondecrease in net FAS/CAS pension adjustment and a higher effective tax rate. On a pension-adjusted basis, earnings per diluted share from continuing operations increased 11 percent to $2.06 from $1.85. Diluted earnings per share for the fourth quarter of 2012 are based on weighted average diluted shares outstanding of 248.9 million compared with 262.7 million in the prior year period, a 5 percentdecrease. During the fourth quarter the company repurchased 7.3 million shares of its common stock for approximately $487 million.

For 2012, earnings from continuing operations totaled $2.0 billion, or $7.81 per diluted share, compared with $2.1 billion, or $7.41 per diluted share in 2011. The change in earnings was principally due to a $268 million decrease in 2012 net FAS/CAS pension adjustment and a higher effective tax rate, which more than offset a $121 millionincrease in segment operating income. The increase in diluted earnings per share reflects higher segment operating income and a lower share count in 2012. Diluted earnings per share for 2012 are based on 253.4 million weighted average shares outstanding compared with 281.6 million weighted average shares outstanding in 2011, a 10 percent decrease. In 2012, the

company repurchased 20.9 million shares of its common stock for $1.3 billion, and $1.5 billion remained on its current share repurchase authorization as of Dec. 31, 2012.

Fourth quarter 2012 operating income increased$25 million, or 3 percent, and operating margin rate expanded 40 basis points to 12.7 percent from 12.3 percent in the prior year period. The improvement in operating income and margin rate reflects a 13 percent increase in segment operating income and a segment operating margin rate of 13.5 percent, which more than offset slightly lower sales and a $67 million decline in net FAS/CAS pension adjustment. On a pension-adjusted basis, fourth quarter 2012 operating income increased $92 million, or 13 percent, to $793 million, and pension-adjusted operating margin rate expanded 140 basis points to 12.2 percent from 10.8 percent.

For 2012, operating income decreased4 percent and operating margin rate was unchanged at 12.4 percent. The change in operating income principally reflects a $268 million decrease in net FAS/CAS pension adjustment, which more than offset a $121 million, or 4 percent, increase in segment operating income to $3.2 billion from $3.1 billion in 2011. In 2012, segment operating margin rate increased 100 basis points to 12.6 percent.

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

Through Dec. 31, 2012, cash provided by continuing operations increased to $2.6 billion from $2.3 billion in the prior year. The increase is principally due to lower discretionary pension pre-funding in 2012. Free cash flow from continuing operations through Dec. 31, 2012, increased to $2.3 billion from $1.9 billion in the prior year due to higher cash provided by operating activities and lower capital expenditures in 2012. Capital expenditures in 2011 included non-recurring expenditures related to the relocation of the company's corporate office.

Before discretionary pension contributions, cash provided by continuing operations totaled $2.8 billion in 2012 compared with $3.0 billion in 2011, and 2012 free cash flow before discretionary pension contributions of $2.5 billion was unchanged from the prior year. The company made discretionary pension plan contributions of $300 million in 2012 and $1.0 billion in 2011. The change in cash provided by continuing operations before the discretionary pension contributions is principally due to higher income taxes paid and lower net income in 2012.

Changes in cash and cash equivalents described in Schedule 3 of this press release include the following items for cash from operations, investing and financing through Dec. 31, 2012:

Operations

• $2.6 billion provided by continuing operations

Investing

• $331 million for capital expenditures

Financing

• $1.3 billion for repurchases of common stock

• $535 million for dividends

• $188 million from exercises of stock options

The company's 2013 financial guidance is based on the assumption that the current six-month Continuing Resolution (CR) will be immediately followed by appropriations, which, even if in the form of a full-year CR, will provide for program spending levels consistent with those set forth in the President's FY 2013 Budget request (PBFY13) and that support and fund the company's programs. Guidance for 2013 also assumes there is no disruption or shutdown of government operations resulting from a federal government debt ceiling breach or lack of immediate appropriations following the current CR, that sequestration is not triggered, and any budgetary approach agreed by Congress to address longer term spending does not result in significant reductions to our customers' FY13 budget levels.

Effective Jan. 1, 2012, the company transferred its missile business, principally the Intercontinental Ballistic Missile (ICBM) program, previously reported in Aerospace Systems to Technical Services. Schedule 6 presents the previously reported and recast results following the realignment.

Aerospace Systems

	Fourth Quarter								Total Year
$ millions	2012			2011			Change		2012			2011			Change

Operating margin rate	13.8		%	12.9		%			12.2		%	12.2		%

Aerospace Systems fourth quarter 2012 sales increased7 percent and 2012 sales increased by less than 1 percent. Increased sales for both periods are principally due to higher volume for unmanned systems, including NATO AGS and Fire Scout, and higher volume for the F-35 and Advanced Extremely High Frequency satellite (AEHF) programs. Higher volume for these programs was partially offset by declines in both periods for the F/A-18 and Joint Surveillance Target Attack Radar System (JSTARS) programs, as well as lower volume for restricted space programs and the termination of a weather satellite program.

Aerospace Systems fourth quarter 2012 operating income increased14 percent and operating margin rate increased to 13.8 percent from 12.9 percent. Higher fourth quarter operating income reflects increased sales volume and improved program performance, which more than offset the impact of lower F/A-18 margin due to that program's transition from the multiyear 2 contract to the lower margin multiyear 3 contract. For 2012, operating income was comparable to the prior year period and operating margin rate was unchanged at 12.2 percent.

Electronic Systems

Sales	$	1,775		$	1,868		(5.0	%)	$	6,950		$	7,372		(5.7	%)

Operating margin rate	18.5		%	13.7		%			17.1		%	14.5		%

Electronic Systems fourth quarter 2012 sales declined 5 percent, which reflects lower volume for infrared countermeasures, LITENING targeting systems, and postal automation programs. Declines in these programs were partially offset by higher volume for space and international programs.

For 2012, sales declined 6 percent, principally due to a decrease of approximately $250 million in postal automation volume and lower volume for infrared countermeasures. Lower postal automation volume includes the impact of the company's decision to de-emphasize its domestic business. These declines were partially offset by higher volume for space programs.

Electronic Systems fourth quarter 2012 operating income increased28 percent, and operating margin rate increased to 18.5 percent from 13.7 percent. Fourth quarter 2012 operating income and margin rate reflect improved program performance as well as the benefit of cost reduction initiatives. Fourth quarter 2011 operating income and margin rate included provisions for contractual matters and higher provisions for reductions in force.

For 2012, operating income increased11 percent, and operating margin rate increased to 17.1 percent from 14.5 percent in 2011. Higher operating income and margin rate reflect an increase in net favorable performance adjustments of approximately $160 million in 2012. Higher net favorable performance

adjustments primarily resulted from improved program performance for several combat avionics programs that completed deliveries, negotiated contract modifications, and successfully mitigated risk. The de-emphasis of the domestic postal automation business, which incurred $50 million of negative adjustments in 2011, also contributed to the increase in net favorable performance adjustments.

Operating margin rate	9.8		%	10.3		%			10.3		%	9.7		%

Information Systems fourth quarter 2012 sales declined 2 percent principally due to the April 2012 divestiture of Park Air Norway, which contributed sales of approximately $30 million in the prior year period. Lower volume also includes the wind down and completion of several programs, offset by higher volume for Consolidated Afloat Network & Enterprise Services (CANES) and the F-35.

For 2012, sales declined 7 percent due to completion or wind down of several programs, including the Joint Tactical Radio System Airborne, Maritime and Fixed (JTRS AMF), I-Kits, Enterprise Network Management, F-22, and certain restricted programs. Lower volume also includes the impact of the County of San Diego IT outsourcing contract and Park Air Norway divestitures, which together accounted for approximately $100 million of the year-over-year change.

Information Systems fourth quarter 2012 operating income decreased6 percent, and operating margin rate totaled 9.8 percent compared with 10.3 percent in the prior year period. The change in fourth quarter operating income reflects lower volume and costs related to affordability initiatives. For 2012, operating income decreased 1 percent and operating margin rate improved 60 basis points to 10.3 percent from 9.7 percent. The decrease in operating income is due to lower volume and the improvement in operating margin rate reflects improved program performance.

Operating margin rate	8.4		%	8.5		%			8.9		%	8.1		%

Technical Services fourth quarter and 2012 sales decreased7 percent and 5 percent, respectively. Declines for both periods are due to portfolio shaping actions and lower volume for the KC-10 and ICBM programs.

Technical Services fourth quarter 2012 operating income decreased7 percent and operating margin rate was 8.4 percent. For 2012, operating income increased 3 percent and operating margin rate increased 80 basis points to 8.9 percent. The improvement in operating income and operating margin rate reflects improved performance for the KC-10 program, which more than offset the impact of lower sales.

Northrop Grumman Reports Fourth Quarter and 2012 Financial Results 16

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.

Pension-adjusted diluted EPS from continuing operations: Diluted EPS from continuing operations excluding the after-tax net pension adjustment per share, as defined below. 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.

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 of 2012 and 2011 financial performance and is reconciled in Table 2.

Free cash flow provided by continuing operations: Cash provided by continuing operations less capital expenditures (including outsourcing contract & 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 provided by 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 is reconciled in Table 2.

Net FAS/CAS 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 2012 and 2011 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 margin rate: Pension-adjusted operating income as defined above, divided by sales. Management uses pension-adjusted operating margin rate, 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, including unallowable or unallocable portions of 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 3, as an internal measure of financial performance of our individual operating segments.

Segment operating margin rate: Segment operating income as defined above, divided by sales. Management uses segment operating margin rate, as reconciled in Table 3, as an internal measure of financial performance.
