Here's a sobering development for Steris Corp. as it seeks to contest the U.S. Federal Trade Commission's effort to keep it from acquiring Synergy Health in a $1.9 billion deal. Reuters reports that following a successful government lawsuit to block the deal, Sysco Corp., the biggest U.S. food distribution company, on Monday dropped plans to merge with US Foods, its biggest rival. The Federal Trade Commission filed a lawsuit to block the deal in February, and a U.S. federal judge ruled in the agency's favor last week. "We have concluded that it's in the best interests of all our stakeholders to move on," said Bill DeLaney, Sysco president and CEO, in a statement. "We believed the merger was the right strategic decision for us and we are disappointed that it did not come to fruition."
