The company's first quarter 2018 results reflect the adoption of Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers, and Accounting Standards Update (ASU) No. 2017-07, Compensation Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, using the full retrospective method. Schedules 4 and 5 at the end of this release present comparable prior period consolidated and segment financial information recast to reflect the adoption of these standards.

First quarter 2018 sales increased 5 percent, due to higher sales in Aerospace Systems and Mission Systems, partially offset by lower sales at Technology Services. First quarter segment operating income increased 3 percent due to higher sales. Segment operating margin rate declined to 11.3 percent due to a lower margin rate at Aerospace Systems. First quarter operating income and margin rate declined to $854 million and 12.7 percent, respectively, compared with $862 million and 13.4 percent in the prior year period, primarily due to a $27 million decrease in net FAS (service)/CAS pension adjustment, partially offset by a $21 million increase in segment operating income.

First quarter interest expense increased $68 million. Other, net increased $21 million due to a $31 million increase in interest income. These changes reflect the company's issuance in October 2017 of $8.25 billion of debt to finance its pending acquisition of Orbital ATK.

The company's first quarter effective tax rate declined to 15.2 percent from 17.5 percent in the prior year period. The lower tax rate reflects the benefit of the Tax Cuts and Jobs Act of 2017, which reduced the federal statutory tax rate to 21 percent from 35 percent. First quarter 2018 tax benefits for research credits were comparable to the prior year period, and excess tax benefits related to employee share-based compensation totaled $26 million in the first quarter of 2018 compared with $47 million in the first quarter of 2017. The first quarter of 2017 also benefited from several other discrete items.

Sales	$	3,280		$	2,984		10	%
Operating income	341			323			6	%
Operating margin rate	10.4		%	10.8		%

Aerospace Systems first quarter 2018 sales increased 10 percent, principally due to higher Manned Aircraft sales. Higher volume for restricted activities and the F-35 and E-2D programs were the primary drivers of increased Manned Aircraft volume. Autonomous Systems and Space Systems sales were slightly higher than the prior year period. Autonomous Systems sales included higher volume on the Fire Scout and Triton programs, partially offset by lower Global Hawk volume. Space sales included higher restricted and Ground Based Strategic Deterrent volume, partially offset by lower intercompany, James Webb Space Telescope and Advanced Extremely High Frequency payload volume.

Northrop Grumman Reports First Quarter 2018 Financial Results 4

Aerospace Systems first quarter 2018 operating income increased 6 percent due to higher sales, and operating margin rate declined to 10.4 percent primarily due to a non-programmatic benefit recognized during the first quarter of 2017 and higher volume on early phase development programs in 2018.

Mission Systems

	First Quarter
($ in millions)	2018			2017			Change
Sales	$	2,883		$	2,800		3	%
Operating income	371			359			3	%
Operating margin rate	12.9		%	12.8		%

Mission Systems first quarter 2018 sales increased 3 percent principally due to higher volume for Sensors and Processing programs, partially offset by lower volume for Cyber and ISR programs. Higher Sensors and Processing sales are primarily due to higher volume on electro-optical/infrared self-protection and targeting programs, F-35 sensors, and restricted programs. Lower volume for Cyber and ISR reflects lower volume on restricted ISR activities. Advanced Capabilities sales were comparable to the prior year period.

Mission Systems first quarter 2018 operating income increased 3 percent, consistent with higher sales, and operating margin rate was comparable to the prior year period.

Technology Services

	First Quarter
($ in millions)	2018			2017			Change
Sales	$	1,144		$	1,190		(4	%)
Operating income	122			129			(5	%)
Operating margin rate	10.7		%	10.8		%

Technology Services first quarter 2018 sales decreased 4 percent due to the completion in 2017 of several programs in System Modernization and Services and Advanced Defense Services. These declines were partially offset by higher volume on several Global Logistics and Modernization programs, including the Special Electronic Mission Aircraft program.

Technology Services first quarter 2018 operating income decreased 5 percent and operating margin rate was comparable to the prior year period.

2018 Guidance

2018 financial guidance reflects the company's judgment based on the information available to the company at the time of this release. The government budget and appropriations processes can impact our customers, programs and financial results. Government budgets, appropriations, including the timing of appropriations, and the occurrence of continuing resolutions and government shutdowns can impact the company's ability to achieve 2018 guidance. 

While the company currently expects its previously announced acquisition of Orbital ATK will close in the first half of this year, 2018 guidance does not reflect the pending acquisition. Additionally, 2018 guidance reflects only six months of interest on the $8.25 billion of debt issued in October 2017 to finance the acquisition. After the close of the acquisition, the company will update its financial guidance to reflect the acquisition.

Northrop Grumman Reports First Quarter 2018 Financial Results 13

Non-GAAP Financial Measures Disclosure: This earnings 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. Definitions for the non-GAAP measures are provided below 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 the release. Other companies may define these measures differently or may utilize different non-GAAP measures.

Segment operating income: Total earnings from our three segments, including allocated pension expense recognized under CAS, and excluding unallocated corporate items and FAS pension expense. This measure may be useful to investors and other users of our financial statements as a supplemental measure in evaluating the financial performance and operational trends of our sectors. This measure should not be considered in isolation or as an alternative to operating results presented in accordance with GAAP. Segment operating income is reconciled in Table 1.

Segment operating margin rate: Segment operating income as defined above, and reconciled in Table 1, divided by sales. This measure may be useful to investors and other users of our financial statements as a supplemental measure in evaluating the financial performance and operational trends of our sectors. This measure should not be considered in isolation or as an alternative to operating results presented in accordance with GAAP.

Free cash flow: Net cash used in operating activities less capital expenditures. We use free cash flow as a key factor in our planning for, and consideration of, acquisitions, stock repurchases and the payment of dividends. This measure may be useful to investors and other users of our financial statements as a supplemental measure of our cash performance, but should not be considered in isolation, as a measure of residual cash flow available for discretionary purposes, or as an alternative to operating cash flows presented in accordance with GAAP. Free cash flow is reconciled in Table 2.
