The combination “will define the future of aerospace and defense,” United Technologies Chief Executive Officer Greg Hayes said in the statement. The bigger company will combine United Technologies’ Pratt & Whitney F-35 fighter jet engines with Raytheon’s Patriot missile-defense products and expertise in areas such as radars, munitions and cybersecurity.
NEW YORK (June 10): United Technologies Corp. agreed to buy Raytheon Co. in an all-stock deal, forming an aerospace and defense giant with US$74 billion ($100.9 billion) in sales in one of the industry’s biggest transactions ever.
The new entity will be called Raytheon Technologies Corp. when the deal closes in the first half of 2020, after United Technologies completes the separation of its Otis elevator and Carrier air-conditioner businesses, the companies said in a statement Sunday. While billed as a merger of equals, current United Technologies shareholders will own most of the company.
