News Release

Rockwell Collins reports third quarter fiscal year 2010 earnings per share of $0.89 on year-over-year sales increase of 12%

Nine month year-to-date 2010 operating cash flow of $440 million increased $59 million compared to the same period in 2009

Overall full year guidance updated with EPS of about $3.50 and operating cash flow increased to about $700 million

CEDAR RAPIDS, Iowa (July 16, 2010) – Rockwell Collins, Inc. (NYSE: COL) today reported net income of $142 million for its fiscal year 2010 third quarter ended June 30, 2010, a decrease of $3 million, or 2%, from fiscal year 2009 third quarter net income of $145 million. Earnings per share was $0.89, a decrease of $0.02 from earnings per share of $0.91 for the same period in 2009.

Third quarter 2010 sales increased $130 million, or 12%, to $1.214 billion compared to sales of $1.084 billion for the same period a year ago. Organic revenue growth was 8%, while incremental sales from the acquisitions of DataPath and Air Routing contributed $43 million, or 4%, to total revenues. Total segment operating margins were 18.8% for the third quarter of 2010 compared to 21.5% for the third quarter of 2009.

Cash provided by operating activities for the first nine months of 2010 totaled $440 million compared to the $381 million reported for the same period last year. The increase resulted primarily from lower payments for employee incentive compensation.

“Despite continued uncertainty in the global economic recovery our business continued to perform very well relative to the expectations we communicated in September, 2009,” said Rockwell Collins Chairman, President and Chief Executive Officer Clay Jones. “Both business segments posted year-over-year increases in revenue for the first time since the fourth quarter of fiscal year 2008 as the commercial markets show solid improvement and our defense business continues its steady progress.”

Mr. Jones went on to state, “Given the benefits of the balance and diversification of our businesses and the strength of our shared services operating model, we are updating several pieces of our overall guidance. Despite higher accruals now expected for employee incentive compensation and the absence of the Federal R&D Tax Credit, we are confident enough in our overall performance to tighten our EPS and increase our operating cash flow guidance.”

Following is a discussion of fiscal year 2010 third quarter sales and earnings for each business segment.

Government Systems

Government Systems, which provides communication and electronic systems, products and services for airborne and surface applications to the U.S. Department of Defense, other government agencies, civil agencies, defense contractors and foreign ministries of defense, achieved third quarter sales of $754 million, an increase of $103 million, or 16%, compared to the $651 million reported for the same period last year. Incremental sales from the May 29, 2009 acquisition of DataPath contributed $34 million of revenue growth.

Airborne solutions sales increased $8 million, or 2%, to $460 million as higher revenues related to tanker and transport aircraft programs were partially offset by lower revenues on fighter jet programs. Surface solutions sales increased $95 million, or 48%, to $294 million. DataPath sales contributed $34 million to acquisition-related revenue growth, while organic sales increased $61 million primarily due to revenues related to a vehicle electronics integration program with the California Highway Patrol and higher sales from a number of international programs.

Government Systems third quarter operating earnings decreased 3% to $153 million, resulting in an operating margin of 20.3%, compared to operating earnings of $158 million, or an operating margin of 24.3%, for the same period last year. The decrease in operating earnings was primarily the result of higher employee compensation and pension expenses, transition costs related to the San Jose, California facility shut-down and higher research and development expenditures, which were partially offset by the benefit of a favorable contract adjustment, reduction in warranty expenses and incremental earnings on higher revenues. Operating margin was also negatively impacted by lower margins on DataPath revenues.

Commercial Systems

Commercial Systems, which provides aviation electronics systems, products and services to air transport, business and regional aircraft manufacturers and airlines worldwide, achieved third quarter sales of $460 million, an increase of $27 million, or 6%, compared to sales of $433 million reported for the same period last year. Incremental sales from the acquisition of Air Routing contributed $9 million of revenue growth.

Sales related to aircraft original equipment manufacturers increased $29 million, or 14%, to $240 million primarily due to higher sales to Boeing resulting from the absence of last year’s post-labor strike inventory rationalization and an increase in 787 revenues, and higher equipment sales for Chinese turbo-prop aircraft. Aftermarket sales increased $11 million, or 6%, to $210 million. Air Routing sales contributed $9 million of the aftermarket revenue growth and organic sales increased $2 million. The increase in organic aftermarket revenues was primarily from higher avionics service and support revenues and an increase in business and regional jet retrofit and spares sales. These increases were partially offset by lower air transport retrofit and spares sales and a decrease in wide-body in-flight entertainment service revenues. Sales related to wide-body in-flight entertainment products decreased $13 million to $10 million.

Commercial Systems third quarter operating earnings were level with the prior year at $75 million, resulting in an operating margin of 16.3% for the third quarter 2010, compared to an operating margin of 17.3%, for the same period a year ago. The decrease in operating margin was primarily attributable to higher employee compensation and pension expenses, partially offset by favorable margins on higher sales volume.

Corporate and Financial Highlights

General corporate expenses that are not allocated to the company’s business segments increased $4 million to $12 million during the third quarter of 2010 due to higher employee compensation and pension expenses. The company’s effective income tax rate of 30.7% for the third quarter of 2010 was lower than the rate of 32.6% for the prior year period as a result of additional tax benefits related to prior year tax returns partially offset by the absence of the Federal Research & Development Tax Credit, which expired December 31, 2009.

During the third quarter of 2010 the company repurchased 0.8 million shares of its common stock at a total cost of $51 million, leaving $92 million available for authorized share repurchases. The company also paid dividends totaling $38 million, or 24 cents per share, on its common stock.

Fiscal Year 2010 Outlook

The following table is a complete summary of the company’s updated fiscal year 2010 financial guidance:

•	Total sales	About $4.7 billion
	– Updated from	$4.6 bil. to $4.8 bil.

•	Total segment operating margin	About 19%
	– Updated from	18.5% to 19.5%

•	Earnings per share(1)	About $3.50
	– Updated from	$3.35 to $3.55

•	Cash flow from operating activities	About $700 million
	– Updated from	$600 mil. to $700 mil.

•	Research & development costs(2)	About $850 million
	– Updated from	$870 mil. to $900 mil.

•	Capital expenditures	About $135 million

(1)

Based on an estimated effective income tax rate in the range of 30% to 31%. The projected effective tax rate assumes the Federal R&D Tax Credit is not renewed before the end of the fiscal year. If the Federal R&D Tax Credit is renewed before the end of the fiscal year, the impact to the effective tax rate guidance would be a decrease of approximately 2 percentage points.

(2)	The decrease in research & development costs is a result of lower customer-funded development programs.
