Synergy Health has dropped more than 15% on concerns about its proposed takeover by US group Steris Corporation.
Traders said a meeting today at the Federal Trade Commission was believed to be looking at the ¢1.9bn cash and share deal, which involves setting up a UK base for tax reasons, something increasingly frowned upon by US authorities.
According to Reuters analysts at Olivetree said there was talk that the FTC may decide to block the proposed takeover, originally announced last October, or demand onerous conditions, sending Synergy down 331p to £18.33.
