Playtech said: “The company has discussed with Plus500 the consequences of the recent developments with the FCA and has agreed to the termination of the merger agreement.”
It also said that the smaller bolt-on $105 million acquisition of Dublin-based financial trading firm AvaTrade, which had been objected to by the central Irish bank, was also no longer likely to go ahead.
Broker Cenkos said the announcement by Playtech had “clearly damaged credibility” and left uncertainties over its cash pile and 9.9% stake in Plus500.
