Rockwell Collins’ third quarter fiscal year 2006 EPS increase 25% to 70 cents on 8% organic revenue growth

CEDAR RAPIDS, Iowa (July 26, 2006) – Rockwell Collins, Inc. (NYSE: COL) today reported net income of $121 million for the third quarter of fiscal year 2006 ended June 30, an increase of $20 million, or 20%, over fiscal year 2005 third quarter net income of $101 million. Earnings per share improved 25% to 70 cents compared to 56 cents for the same period last year. Earnings per share growth exceeded the growth rate in net income due to the favorable effect of the company’s share repurchase program. Total segment operating margin for the third quarter improved 250 basis points to 20.6% compared to 18.1% last year.

Third quarter sales were $964 million, an increase of $74 million, or 8% from the $890 million reported last year. For the first nine months of fiscal year 2006 cash flow from operating activities totaled $313 million compared to $352 million for the same period a year ago. The lower year-to-date cash flow from operating activities was principally due to the net effect of higher income tax payments offset by lower voluntary pension plan contributions.

“Our third quarter financial results reflect another demonstration of excellent execution by both our Government and Commercial Systems businesses,” said Rockwell Collins Chairman, President and Chief Executive Officer, Clay Jones. “I’m particularly pleased by our ability to continue achieving productivity improvements that translate into profitability growth at rates considerably higher than our revenue growth,” concluded Jones, noting that total segment operating earnings increased 24% and resulted in a total segment operating margin in excess of 20% for the first time.

Current year third quarter earnings include $4 million ($3 million after tax, or 2 cents per share) of stock-based compensation costs related to the company’s adoption of Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment, on October 1, 2005, and $3 million (or 2 cents per share) of higher income tax expense principally due to the expiration of the Federal Research and Development Tax Credit on December 31, 2005. Legislation extending the availability of tax credits beyond December 31, 2005 has yet to be enacted.

Following is a discussion of sales and earnings for each business segment.

Government Systems

Government Systems, which provides aviation electronics, navigation and precision guidance, communications and simulation systems, products and services to the United States government, foreign militaries and manufacturers of military platforms, achieved third quarter sales of $499 million, an increase of $37 million, or 8%, compared to the $462 million reported for the same period last year.

Defense electronics systems and products sales increased $19 million, or 6%, to $335 million. Higher Defense Advanced GPS Receiver (DAGR) and fixed and rotary wing electronics systems upgrade program revenues were partially offset by lower simulation and training revenues due to delayed customer procurements. Defense communications sales increased $18 million, or 12%, to $164 million. Higher ARC-210 radio and advanced communication program revenues more than offset lower Joint Tactical Radio System program revenues.

Government Systems’ third quarter operating earnings increased $17 million, or 21% to $99 million, or an operating margin of 19.8%, compared to operating earnings of $82 million, or an operating margin of 17.7%, for the same period last year. The higher operating earnings and operating margin were primarily attributable to the combination of the higher sales, productivity improvements and a more favorable proportion of higher margin production revenues, partially offset by higher discretionary research and development costs.

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 $465 million, an increase of $37 million, or 9%, compared to sales of $428 million reported for the same period last year. Increased demand for new business and air transport aircraft, spares and avionics retrofits drove the revenue growth.

Sales to airlines and aircraft original equipment manufacturers (OEMs) increased $26 million, or 12%, to $249 million. Significantly higher business jet avionics and cabin electronics systems revenues and higher air transport avionics sales more than offset lower regional jet avionics and in-flight entertainment systems revenues. Commercial Systems’ aftermarket revenues increased $11 million, or 5%, to $216 million. Higher revenues from retrofit and spares activities more than offset a $4 million decline in regulatory mandate program revenues.

Commercial Systems’ third quarter operating earnings increased $21 million, or 27%, to $100 million, or an operating margin of 21.5%, compared to operating earnings of $79 million, or an operating margin of 18.5%, for the same period a year ago. The higher operating earnings and operating margin primarily resulted from the combination of the higher sales, productivity improvements and a lower proportion of lower margin in-flight entertainment systems revenues, partially offset by higher research and development costs.

Financial Highlights

Based on the strength of its balance sheet and operating cash flow, the company continued to execute on a capital deployment strategy targeted at providing additional shareowner value.

• The amount of the regular quarterly per share dividend was increased by 33% to 16 cents from 12 cents effective with the dividend paid on June 5, 2006.

• The company repurchased 2.2 million shares of common stock at a total cost of $125 million. Total authorized share repurchases available beyond June 30, 2006 stand at $331 million.

Fiscal Year 2006 Outlook

The company has updated certain elements of its full fiscal year 2006 financial guidance as follows:

• Government Systems’ full year sales are now projected to increase over fiscal year 2005 sales by about 14% (previously in the range of 14% to 16%).

• Commercial Systems’ full year sales are now expected to increase over fiscal year 2005 sales by about 10% (previously in the range of 8% to 10%).

• Due to the company’s higher than anticipated segment operating margin performance in the first nine months of the fiscal year, expectations for Government and Commercial Systems full year segment operating margins have been raised.

• Government Systems’ full year operating margins are expected to be in the range of 19% to 19.5% (previously about 19%).

• Commercial Systems’ full year operating margins are projected to be about 20% (previously in the range of 19% to 20%).

2

• Earnings per share are projected to be in the range of $2.65 to $2.70 (previously in the range of $2.60 to $2.70). In addition, management now expects that the new EPS guidance range will accommodate a full year effective income tax rate of 31% to 32% that could result if legislative action is not enacted during the fourth quarter to retroactively extend the availability of federal research and development tax credits from December 31, 2005 to at least the end of the 2006 fiscal year.

• Cash flow from operating activities is now expected to be about $550 million (previously about $600 million), as a result of the company’s $50 million voluntary contribution to its U.S. qualified defined benefit pension plan.

• Research and development costs are expected to total about $725 million (previously about $690 million).

The U.S. Air Force successfully demonstrated several applications of the Rockwell Collins Tactical Targeting Network Technology (TTNT) during the Joint Expeditionary Force experiment held recently at Nellis Air Force Base. TTNT provided the high bandwidth, reliable, ad-hoc network to connect fighter, bomber, and command and control aircraft, as well as mobile and fixed forward ground nodes to extend the reach of Internet Protocol-enabled applications and to integrate the TTNT sub-network with the fixed ground network. An advanced communications program developed by the Defense Advanced Research Projects Agency, TTNT is the airborne networking waveform for the Multi-functional Information Distribution System Joint Tactical Radio System (MIDS-JTRS) program,

Rockwell Collins and Thales signed a strategic agreement for the joint development and pursuit of international programs for tactical ground communications through a new product line of radios called FlexNet. The new single- and multi-channel FlexNet radios will be capable of supporting the FlexNet waveform, which provides for high data rate ad-hoc networked communications and multimedia services. This enhanced capability increases the level of information which can be exchanged between users, introduces new possibilities of cooperative combat engagement between different units, and provides the mobility required by armed forces. Based on an open and secure architecture – compliant with Software Communication Architecture – the FlexNet radios will accommodate future technology insertions or requirement upgrades.

Data Link Solutions (DLS) and Thales agreed to cooperatively produce and sell MIDS-JTRS terminals for the global market. DLS, a joint venture between Rockwell Collins and BAE Systems, is currently developing MIDS JTRS under an $82 million contract and is also performing under an additional $9 million development contract to insert the Tactical Targeting Networking Technology waveform into the MIDS-JTRS terminal. The base MIDS-JTRS terminal, which will provide current MIDS Link 16 and tactical air navigation functions, as well as three additional programmable channels to run various communications, navigation and command-and-control waveforms, is scheduled to be complete in September 2007; with additional European- unique developments running through 2009.

The U.S. Air Force selected Rockwell Collins to develop next-generation Global Positioning System (GPS) technology as part of the Modernized User Equipment (MUE) Receiver Card Development program. To be executed through October 2007, the $28 million contract calls for the preliminary design of modernized receiver cards for ground and airborne applications, establishing first proof of design for the modernized GPS architecture. Completion of the receiver card development, test and security certification will be accomplished under a government exercisable contract option for these tasks. This program represents the military user equipment portion of a next-generation GPS system that adds a new military signal and security architecture, enabling enhanced integrity, exclusivity and improved anti-jam capabilities.

The U. S. Navy and Air Force each awarded a contract to Rockwell Collins for simulation and training system programs. The U.S. Navy award was for its MH-60 Weapons Load Trainer (WLT) program. The contract, valued at $26 million, calls for Rockwell Collins to modify an existing H-60F trainer and build four new H-60 WLTs. The U.S. Air Force award is for the provision of concurrency updates, training modifications and support for the U.S. Air Force’s B-1B Training System. Under a 6-year contract worth $95 million, Rockwell Collins will support five Weapons System Trainers, two Mission Trainers, five Cockpit Procedure Trainers and 18 Maintenance Trainers. Rockwell Collins Simulation and Training Solutions has been providing B-1B training services for the Air Force since 1999.

Rockwell Collins made the first deliveries of its Core Network cabinet to support the Boeing 787 Dreamliner program. The Core Network cabinet plays a key role in Boeing’s objective to ‘e-enable’ the entire aircraft. Utilizing commercial open standards, the Core Network hosts a wide variety of third party applications, and manages on board information flow to improve airline operations efficiency. The units delivered will support the development of the Health Maintenance System for the Boeing 787. In addition to the core network cabinet, Rockwell Collins is the supplier for the 787 flight deck display system and crew alerting system, pilot controls, communication and surveillance systems and the aircraft’s common data network. Rockwell Collins also serves as the systems integrator for each of these elements.

Rockwell Collins announced its next generation of weather radar, the MultiScan Hazard Detection^TM system, which will enable safer, smoother and more efficient flights. The system includes five ground-breaking technologies that go beyond today’s most advanced radar systems by adding predictive weather analysis and hazard detection features. These technologies include: Directed Sequential Hazard Assessment, Flight Path Hazard Analysis, Storm Top Information, Predictive Overflight Protection and Enhanced Turbulence Detection.

Xiamen Airlines selected a full suite of Rockwell Collins’ avionics for 15 new Boeing 737-800 aircraft. The agreement, which includes the selection of the Rockwell Collins WXR MultiScan Weather Radar, also calls for an option on five additional aircraft with deliveries scheduled to begin in July 2006.

Rockwell Collins extended its current Preferred Supplier Agreement (PSA) with Air France through 2010, and signed a new five year PSA with KLM Royal Dutch Airlines. Air France and KLM Royal Dutch Airlines are subsidiaries of Air France-KLM. The PSAs provide for the purchase of Rockwell Collins’ communication, navigation and surveillance avionics by the two airlines for their forward fit aircraft and retrofit activities, while enabling improved avionics performance and reliability through a continuous improvement program. The Air France agreement also covers data link avionics, while a separate KLM agreement covers MultiScan weather radar on KLM’s Boeing 777 aircraft.
