Sysco had planned to divest those centers to try to quell regulators' antitrust concerns, were the merger with US Foods to go through. The companies first announced the merger in December 2013, and in February the Federal Trade Commission filed a lawsuit against it, requesting the preliminary injunction that federal judge Amit Mehta granted last week. The company Monday also detailed for investors its next steps, including spending $3 billion to buy back shares over the next two years, currently worth about 13 percent of outstanding stock.
