News Release

Rockwell Collins reports second quarter fiscal year 2008 earnings per share of $1.03 on sales of $1.186 billion; fiscal year 2008 earnings per share guidance range increased to $3.95 to $4.05

CEDAR RAPIDS, Iowa (Apr. 24, 2008) - Rockwell Collins, Inc. (NYSE: COL) today reported net income of $168 million for the second quarter of fiscal year 2008 ended March 31, 2008, an increase of $28 million, or 20% over fiscal year 2007 second quarter net income of $140 million. Earnings per share improved 21 cents, or 26%, to $1.03 compared to earnings per share of 82 cents last year. Earnings per share growth exceeded the growth rate in net income by 6 percentage points, principally due to the favorable effect of the company’s share repurchase program.

Second quarter fiscal year 2008 sales increased $103 million, or 10%, to $1.186 billion compared to year ago second quarter sales of $1.083 billion. Cash provided by operating activities of $130 million for the first six months of fiscal year 2008 was lower than the $186 million reported for the same period last year as the impact of higher net income was more than offset by an increase in working capital utilization.

“These results clearly demonstrate the level of performance we can achieve through the unique combination of our balanced exposure to government and commercial markets, the diversity of our customer base within each market, and the successful operation of our efficient shared service business model,” said Rockwell Collins Chairman, President and Chief Executive Officer Clay Jones. “Despite higher research and development investments and a decline in Commercial Systems’ aftermarket revenues, we achieved double-digit growth in total company revenues as well as higher year-over-year segment operating margins in both our Commercial and Government Systems businesses.”

“This excellent operational performance was further enhanced by taking advantage of our strong balance sheet capacity and repurchasing an additional 3 million shares of common stock during the quarter,” said Jones, noting that over the past 12 months, the company has repurchased 9 million shares and reduced its total outstanding share count by 4%.

Commenting on the company’s assessment of current Aerospace and Defense market conditions and the company’s updated financial projections for the 2008 fiscal year, Jones concluded, “Although we expect a weaker U.S. economic environment in 2008, market conditions for our Commercial and Government Systems businesses continue to be solid. Accordingly, we remain on track toward meeting our full year revenue projections. In addition, and due in part to higher profitability expectations in Government Systems, we raised our full year earnings per share forecast for a second consecutive quarter.”

As anticipated, the company's second quarter fiscal year 2008 net income and earnings per share include the impact of a net 7 cent earnings per share benefit resulting from the favorable settlement of certain tax matters, partially offset by lower research and development tax credits due to the expiration of federal research and development tax credit legislation on December 31, 2007.

Following is a discussion of fiscal year 2008 second quarter sales and earnings for each business segment.

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 $610 million, an increase of $68 million, or 13%, compared to sales of $542 million reported for the same period last year.

Sales to airlines and aircraft original equipment manufacturers (OEMs) increased $79 million, or 29%, to $351 million. Market share gains and increased demand for new air transport, business and regional aircraft led to higher avionics sales across all three market areas, with particularly strong growth in sales to business and regional aircraft OEMs. In-flight entertainment system sales were also higher. Commercial Systems aftermarket revenues declined $11 million, or 4%, to $259 million. Higher revenues from service and support activities and sales of equipment for Boeing 787 simulators were more than offset by the anticipated impact of lower in-flight entertainment and business aircraft retrofit and spares revenues as well as lower regulatory mandate program revenues.

Commercial Systems’ second quarter operating earnings increased $18 million, or 15%, to $140 million, delivering an operating margin of 23.0%, compared to operating earnings of $122 million and an operating margin of 22.5% for the same period a year ago. The increase in operating earnings and operating margins was primarily due to the combination of higher revenues, productivity improvements, and higher royalty income, partially offset by higher research and development costs and the absence of a favorable contract option exercise adjustment recognized in last year’s second quarter.

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 $576 million, an increase of $35 million, or 6%, compared to sales of $541 million reported for the same period last year. Incremental sales from the August 2007 acquisition of Information Technology & Applications Corporation (ITAC) contributed $4 million, or 1 percentage point of the Government Systems revenue growth.

Airborne solutions sales increased $12 million, or 3%, to $399 million primarily due to higher integrated electronics systems revenues from international C-130 upgrade programs and the German Army CH-53 G helicopter program. Surface solutions sales increased $23 million, or 15%, to $177 million principally due to sales related to a United Kingdom Ministry of Defence precision targeting system program, higher Defense Advanced GPS Receiver (DAGR) and Ground-Based GPS Receiver Application Module (GB-GRAM) program sales, and the incremental revenues from the ITAC acquisition.

Government Systems’ second quarter operating earnings increased $8 million, or 7%, to $115 million, resulting in an operating margin of 20.0%, compared to operating earnings of $107 million and an operating margin of 19.8% for the same period last year. The increase in operating earnings and operating margins was principally due to the higher sales volume.

Financial Highlights:

During the second quarter of fiscal year 2008, the company continued to deploy its operating cash flow and utilize the strength of its balance sheet to enhance shareowner value:

· Common stock repurchases totaled 3 million shares at a total cost of $190 million. As of March 31, 2008, the company’s share repurchase program has $326 million of share repurchase authorization remaining.

· Dividends paid to shareowners of common stock totaled $26 million, or 16 cents per share.

In addition, on April 15, 2008, the company’s Board of Directors approved an increase in the company’s quarterly dividend of 8 cents per share, or 50%, to 24 cents per share on its common stock. The new quarterly dividend rate is effective with the next dividend payable on June 2, 2008, to shareholders of record at the close of business on May 12, 2008.

Fiscal Year 2008 Outlook

The company is today making the following adjustments to its full fiscal year 2008 financial guidance:

· Government Systems’ segment operating margins are expected to be slightly higher than fiscal year 2007 full year segment operating margins of 19.8% (previously slightly lower than fiscal year 2007 full year segment operating margins). Accordingly, the company expects total segment operating margins to be in the range of 22% to 22.5% (previously about 22%).

· The company’s effective income tax rate is expected to be in the range of 31.5% to 32.5% (previously in the range of 32.5% to 33.5%).

· Earnings per share are projected to be in the range of $3.95 to $4.05 (previously in the range of $3.85 to $4.00).

The following table is a complete summary of the company’s updated fiscal year 2008 financial guidance:

·Total sales	About $4.75 billion
·Total segment operating margin	22% to 22.5%
·Earnings per share(1)	$3.95 to $4.05
·Cash flow from operating activities(2)	$675 million to $725 million
·Research & development costs	$925 million to $950 million
·Capital expenditures	About $170 million

(1) Legislation allowing for federal research and development tax credits (R&D Tax Credits) expired on December 31, 2007. The guidance range for earnings per share assumes federal research and development tax credit legislation is not retroactively extended beyond December 31, 2007 during the company’s 2008 fiscal year.

(2) The range of projected cash flow from operating activities accommodates a discretionary qualified defined benefit pension plan contribution of up to $75 million. In addition, the range of projected cash flow from operating activities anticipates the collection of approximately $70 million to $80 million of receivables related to the Boeing 787 program. Collection of these receivables during fiscal year 2008 may be at risk due to the current projected delivery date of the first aircraft occurring in the fourth quarter of our 2009 fiscal year.

Note: The company operates on a 52/53 week fiscal year with quarterly reporting periods ending on the Friday closest to the last calendar day of the quarter. For ease of presentation, March 31 and September 30 are utilized consistently throughout this press release to represent the period end date.

(1) The $3 million favorable restructuring adjustment in the second quarter of fiscal year 2007 was principally due to lower than expected employee separation costs related to the business realignment and facility rationalization actions announced in the fourth quarter of fiscal year 2006.

(2) The company’s effective income tax rate for the second quarter of fiscal year 2008 was 27.6% compared to 33.3% for the second quarter of fiscal year 2007. The lower effective income tax rate in the current year second quarter was primarily due to the recognition of an approximate 7 percentage point discrete tax benefit related to the resolution of certain tax matters partially offset by the recognition of lower research and development tax credits due to the December 31, 2007 expiration of Federal Research and Development Tax Credit legislation.

(3) The company’s effective income tax rate for the first six months of fiscal year 2008 was 30.6% compared to 30.1% for the same period a year ago. The effective income tax rate for the first six months of fiscal year 2008 includes an approximate 3.5 percentage point benefit related to the favorable resolution of certain tax matters in the second quarter, partially offset by the recognition of lower research and development tax credits. The effective income tax rate for the first six months of fiscal year 2007 includes an approximate 3 percentage point benefit related to the first quarter retroactive recognition of research and development tax credits attributable to the period from January 1, 2006 to September 30, 2006 as legislation was enacted during the first quarter of fiscal year 2007 that extended the availability of R&D Tax Credits from January 1, 2006 through December 31, 2007.
