Thermo Fisher Scientific Inc. will buy FEI Co. for about $4.2 billion, gaining imaging technology for the life sciences and materials science industries, according to Bloomberg, The boards of the two companies unanimously approved the deal, in which Thermo Fisher will pay $107.50 a share in cash, the companies said in a statement Friday. That represents a 14 percent premium to FEI’s closing share price of $94.58 on Thursday. FEI produces electron microscopes which are used to analyze proteins, giving Waltham, Massachusetts-based Thermo Fisher a complementary product line to its mass spectrometry systems. Based in Hillsboro, Oregon, FEI has more than 3,000 employees worldwide and has operations mainly in Europe and the U.S. FEI, which had 2015 revenues of $930 million, will become part of Thermo Fisher’s Analytical Instruments Segment. The transaction will immediately add to Thermo Fisher’s earnings and provide cost savings, Chief Executive Officer Marc Casper said in the statement. Haven't heard anything about FEI before this deal was announced, but looks like it fits into Thermo's business just perfectly. Good for both!
