News Release

Rockwell Collins reports first quarter 2012 earnings per share of $0.86

CEDAR RAPIDS, Iowa (January 19, 2012) - Rockwell Collins, Inc. (NYSE: COL) today reported first quarter fiscal year 2012 income from continuing operations of $130 million compared to $150 million in the same period last year. Earnings per share from continuing operations for the quarter were $0.86, a decrease of $0.09, or 9%, from earnings per share of $0.95 in the first quarter of 2011. Prior year results included a favorable impact to income tax expense of $21 million, or 13 cents per share, related to differences in the availability of the Federal R&D Tax Credit. Excluding the impact of these prior year tax-related items, earnings per share in the first quarter of 2012 would have been up 4 cents, or 5%, when compared to last year.

The company reported total sales of $1.1 billion for the first quarter of 2012, which were down 1% when compared to the same period a year ago. Total segment operating earnings increased 2% to $218 million, or 19.9% of sales, for the first quarter of 2012 compared to $213 million, or 19.3% of sales, for the first quarter of 2011.

“First quarter sales were in-line with our expectations as continued growth in Commercial Systems nearly offset the decline in Government Systems,” said Rockwell Collins Chairman, President and Chief Executive Officer, Clay Jones. “Our focus on improved operating performance enabled Government Systems to maintain 20% operating margins despite a 10% decline in sales, while Commercial Systems margins expanded by 170 basis points. This resulted in an increase to total segment operating earnings even as sales declined modestly. Additionally, we exercised some of our balance sheet flexibility this quarter through more aggressive share repurchases, which reduced the outstanding share count by more than 4%, returning significant value to our shareowners.”

Jones went on to state, “I'm encouraged by the improved market environment this quarter, including passage of the 2012 Defense Appropriations bill and continued robust commercial market conditions, which strengthens my confidence in our 2012 earnings per share guidance range of $4.40 to $4.60.”

Following is a discussion of fiscal year 2012 first quarter sales and earnings for each business segment. Commercial Systems' segment results exclude the results of the Rollmet business for all periods presented. The divestiture of Rollmet occurred during the fourth quarter of fiscal year 2011 and is classified as a discontinued operation.

Commercial Systems

Commercial Systems, which provides aviation electronics systems, products and services to air transport, business and regional aircraft manufacturers and airlines worldwide, achieved 2012 first quarter sales of $511 million, an increase of $57 million, or 13%, compared to sales of $454 million reported for the same period last year.

Sales related to aircraft original equipment manufacturers increased $32 million, or 14%, to $265 million driven by higher product deliveries for the Bombardier Global and Challenger platforms, and increased sales of avionics to Boeing resulting from higher production rates for 777 and 747-8 aircraft. Aftermarket sales increased $27 million, or 14%, to $221 million primarily driven by increased sales of spares related to new Boeing aircraft, para-military programs and Chinese regional aircraft as well as higher service and support sales.

Commercial Systems first quarter operating earnings increased $19 million, or 23%, to $101 million, resulting in an operating margin of 19.8%, compared to operating earnings of $82 million, and an operating margin of 18.1%, for the same period a year ago. The increase in operating earnings and margin was primarily attributable to higher sales volume, partially offset by the absence of a $7 million favorable adjustment to customer incentives recorded in the prior year.

Government Systems

Government Systems provides a broad range of electronic products, systems and services to customers including the U.S. Department of Defense, state and local governments, other government agencies, civil agencies, defense contractors and foreign ministries of defense around the world. Sales in the first quarter of 2012 were $583 million, a decrease of $67 million, or 10%, compared to the $650 million reported for the same period last year.

Avionics sales increased $9 million, or 3%, from the first quarter of 2011 due to increased sales for tanker and rotary-wing programs, partially offset by a decline resulting from the completion of deliveries for the KC-135 GATM program and a reduction in simulation and training program revenues. Communication product sales declined by $12 million, or 8%, primarily due to lower Joint Tactical Radio System revenue for the Ground Mobile Radio variant as well as lower deliveries of satellite communication terminals. Surface solutions sales decreased $46 million, or 43%, resulting from the impact of two programs terminated for convenience in the third quarter of 2011 and fewer deliveries of public safety vehicle systems. Sales of Navigation products decreased by $18 million, or 25%, driven by fewer deliveries of Defense Advanced GPS Receiver products.

Government Systems first quarter operating earnings of $117 million resulted in an operating margin of 20.1%, compared to operating earnings of $131 million, and an operating margin of 20.2%, for the same period last year. The decrease in operating earnings was primarily due to lower sales volume, partially offset by the benefit realized from prior year restructuring actions.

Corporate and Financial Highlights

The company's effective income tax rate was 33% for the first quarter of 2012 compared to a rate of 21.5% for the same period last year. The prior year tax rate included a favorable adjustment related to the retroactive reinstatement of the Federal R&D Tax Credit and also included a full year's benefit from the Federal R&D Tax Credit. Since the Federal R&D Tax Credit has not been reinstated, the current year tax rate only has a three month benefit, which must be allocated across the full year and contributes to the increased effective tax rate. See additional disclosures below related to these tax-related items.

Cash used for operating activities was $64 million for the first quarter of 2012, compared to cash provided by operating activities of $57 million in the prior year. The $121 million reduction in cash from operations was primarily driven by $62 million of higher employee incentive payments, a $47 million increase in pension funding and $20 million of higher income tax payments related to differences in the availability of the Federal R&D Tax Credit.

During the first quarter of 2012, the company issued $250 million of unsecured ten year notes at an interest rate of 3.10%. The proceeds from the debt, supplemented by cash on hand, was used to repurchase 7.1 million shares of common stock in the first quarter of 2012 at a total cost of $385 million. The remaining share repurchase authorization as of December 31, 2011 was $318 million. The company also paid dividends on its common stock totaling $36 million, or 24 cents per share.

Discontinued Operations

During the fourth quarter of 2011, the company sold the Rollmet product line. The divestiture has been accounted for as a discontinued operation for all periods presented. Certain prior period amounts have been reclassified to conform to the current year presentation. For the three months ended December 31, 2010, Commercial Systems sales have been reduced by $6 million and Commercial Systems operating earnings have been reduced by $2 million.
