News Release

Rockwell Collins reports second quarter fiscal year 2010 earnings per share of $0.93

o Second quarter 2010 sales of $1.142 billion were flat and earnings per share of $0.93 decreased 10% from the same period in 2009

o Six month year-to-date 2010 operating cash flow of $280 million increased $143 million compared to the same period in 2009

CEDAR RAPIDS, Iowa (April 23, 2010) – Rockwell Collins, Inc. (NYSE: COL) today reported net income of $148 million for its fiscal year 2010 second quarter ended March 31, 2010, a decrease of $16 million, or 10%, from fiscal year 2009 second quarter net income of $164 million. Earnings per share was $0.93, a decrease of $0.10 from earnings per share of $1.03 for the same period in 2009.

Second quarter 2010 sales increased $4 million to $1.142 billion compared to sales of $1.138 billion for the same period a year ago. Incremental sales from the acquisitions of DataPath and Air Routing contributed $87 million of revenue growth. The year-over-year organic revenue decline of $83 million resulted primarily from continued weakness in business and regional jet OEM revenues, lower commercial aerospace aftermarket revenues and a decline in sales of Defense Advanced GPS Receivers (DAGRs). Total segment operating margins were 19.2% for the second quarter of 2010 compared to 22.4% for the second quarter of 2009.

Cash provided by operating activities for the first six months of 2010 totaled $280 million compared to the $137 million reported for the same period last year. The increase resulted primarily from lower employee incentive compensation payments and improved cash receipts from customers.

“I am pleased with our second quarter financial results as revenue tracked to expectations and combined segment operating margins were once again at the upper end of our guidance,” said Rockwell Collins Chairman, President and Chief Executive Officer Clay Jones. “Our operating performance also enabled us to realize a significant increase in operating cash flow.”

Mr. Jones went on to state, “Market indicators continue their positive vector giving us increased confidence that sequential increases in sales and profits will allow us to achieve our fiscal year 2010 expectations and position us well for fiscal year 2011.”

Following is a discussion of fiscal year 2010 second 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 second quarter sales of $693 million, an increase of $80 million, or 13%, compared to the $613 million reported for the same period last year. Incremental sales from the acquisition of DataPath contributed $78 million of revenue growth.

Airborne solutions sales increased $24 million, or 6%, to $455 million as higher revenues related to tanker, transport and special mission aircraft programs were partially offset by lower revenues on fighter jet programs. Surface solutions sales increased $56 million, or 31%, to $238 million. DataPath sales contributed $78 million to revenue growth, while organic sales declined $22 million primarily due to lower sales for the DAGR program.

Government Systems second quarter operating earnings increased 3% to $150 million, resulting in an operating margin of 21.6%, compared to operating earnings of $145 million, or an operating margin of 23.7%, for the same period last year. The increase in operating earnings was primarily the result of higher sales volume, while operating margins declined due to higher employee compensation and pension expenses and an increase in company funded R&D expense.

Commercial Systems

Commercial Systems, which provides aviation electronics systems, products and services to air transport, business and regional aircraft manufacturers and airlines worldwide, achieved second quarter sales of $449 million, a decrease of $76 million, or 14%, compared to sales of $525 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 air transport aviation electronics decreased $8 million, or 3%, to $251 million as lower aftermarket hardware and service revenues and reduced Wide-body IFE product sales were partially offset by an increase in air transport OEM sales from higher sales of airline selectable equipment and slightly higher shipset delivery rates to Boeing. Business and regional aviation electronics sales decreased $68 million, or 26%, to $198 million. Air Routing sales contributed $9 million to revenue growth, while organic sales declined $77 million as a result of a reduction in business and regional jet OEM sales from reduced OEM production rates and a reduction in aftermarket hardware sales, which was partially offset by an increase in service revenues.

Commercial Systems second quarter operating earnings decreased 37% to $69 million, resulting in an operating margin of 15.4%, compared to operating earnings of $110 million, or an operating margin of 21.0%, for the same period a year ago. The decrease in operating earnings and margin was primarily attributable to lower sales volume and higher employee compensation and pension expenses, partially offset by lower company funded research and development costs.

Corporate and Financial Highlights

General corporate expenses that are not allocated to the company’s business segments increased $6 million to $13 million during the second quarter of 2010 due to higher employee compensation and pension expenses. The company’s effective income tax rate of 24.5% for the second quarter of 2010 was lower than the rate of 31.7% for the prior year period resulting from the favorable impact of the IRS completing its examination of the taxable years ended September 30, 2006 and 2007. This benefit was partially offset by unfavorable impacts from the expiration of the Federal R&D Tax Credit as of December 31, 2009 and changes to the tax treatment of the Medicare part D subsidy related to the Patient Protection and Affordable Care Act, which resulted in an increase to the company’s effective tax rate of about 2 percentage points and 1 percentage point, respectively.

During the second quarter of 2010 the company repurchased 0.7 million shares of its common stock at a total cost of $38 million, leaving $143 million available for authorized share repurchases. The company also paid dividends totaling $37 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 fiscal year 2010 financial guidance, which is unchanged from the financial guidance initially provided on September 17, 2009:

•	Total sales	$4.6 Bil. to $4.8 Bil.
•	Total segment operating margins	18.5% to 19.5%
•	Earnings per share(1)	$3.35 to $3.55
•	Cash flow from operations	$600 Mil. to $700 Mil.
•	Research & development costs	$870 Mil. to $900 Mil.
•	Capital expenditures	about $135 Mil.

(1) Based on an estimated effective income tax rate in the range of 30% to 31%. The projected effective tax rate no longer requires the extension of the Federal R&D Tax Credit before the end of the fiscal year. If the Federal R&D Tax Credit is extended before the end of the fiscal year, the impact to the effective tax rate guidance would be a decrease of approximately 1.5 percentage points.
