Gambling technology company Playtech has said it is confident about achieving strong growth in 2015 after a good start to the fourth quarter.

Playtech shares jumped five per cent on Thursday, making it the top gainer on the FTSE-250 midcap index.

Playtech, the online gaming and betting software provider founded by Israeli billionaire Teddy Sagi, said it expected regulatory approval for its acquisition of foreign exchange trading platform provider Plus500 by the end of November.

The company also said it was formally challenging a Central Bank of Ireland decision opposing its $105-million acquisition of online derivatives broker Ava Trade.

Isle of Man-based Playtech entered the forex trading market earlier this year, where the sudden removal of a long-held ceiling on the Swiss franc in January has spurred merger and acquisition activity.

The company bought a majority stake in TradeFx and then strengthened its hand by then snapping up Plus500 and Ava Trade.

Both the AVA Trade and Plus500 deals had been expected to be completed by the end of September.

Playtech, which also bought Scottish company YoYo Games in a deal worth £14m in February, said average daily revenue in its gaming division for the first 27 days of the fourth quarter was 14 per cent higher than in the same period a year earlier.

Third-quarter group revenue soared 47 per cent, with regulated revenue accounting for over half of the group's revenue.
