FRANKFURT—Shares in Linde dropped as much as 10 percent on Monday after the German industrial gases group’s planned $86 billion merger with U.S. rival Praxair was thrown into doubt by more demands from U.S. antitrust regulators.
The U.S. Federal Trade Commission (FTC) is asking for more assets to be sold than previously anticipated and also wants prospective buyers to meet certain other requirements, Linde said in a statement on Sunday.
