The FTC issued an administrative complaint charging that Steris Corporation’s proposed $1.9 billion acquisition of Synergy Health plc would violate the antitrust laws by significantly reducing future competition in regional markets for sterilization of products using radiation, particularly gamma or x-ray radiation. The Commission also authorized agency staff to seek a temporary restraining order and preliminary injunction in federal court to maintain the status quo pending an administrative trial on the merits. According to the FTC, it is unlikely that new competitors in the market for contract radiation sterilization services would replicate the competition that would be eliminated by the merger. The Commission alleged that the challenged acquisition would eliminate likely future competition between Steris’s gamma sterilization facilities and Synergy’s planned x-ray sterilization facilities in the United States, thus depriving customers of an alternative sterilization service and additional competition. On September 25, 2015 the district court denied the FTC motion for a PI. On October 30, the Commission dismissed the administrative complaint.
