Thermo Fisher ($TMO) has closed its mammoth $13.6 billion buyout of Life Technologies, barely a few days after U.S. antitrust regulators signed off on the deal. The acquisition breaks down to $76.13 in cash per fully diluted common share, plus the assumption of $1.5 billion in net debt. The Waltham, MA, laboratory sealed the deal after obtaining regulatory sign-offs from European, Chinese and then U.S. regulators, and had to agree to sell off certain divisions before the Life Tech buyout could be completed.
