Partygaming's acquisition of online bingo specialist Cashcade has got the thumbs up from brokers but it may be bad news for rival online gaming firm 888."The deal is negative for 888, as Cashcade is a major client for 888's software and 888 potentially loses this relationship," notes Nick Batram of broker KBC Peel Hunt. "However, we would regard any significant sell-off of 888 as a buying opportunity," Batram adds.KBC estimates that the acquisition will enhance current year's earnings by about 4%, pushing profit before tax up to about £99m and earnings per share to about 21p. Next year, KBC sees the deal giving a 10% boost to earnings.Broker Daniel Stewart also likes the deal but thinks Cashcade's deal with 888 will remain in place, which will limit the opportunities for synergies."We view this deal as extremely attractive, providing an immediate boost to earnings and a market-leading position in online bingo. The acquisition is an ideal strategic fit for the group," the broker said."We continue to expect further industry consolidation and robust trading from PartyGaming, with considerable potential positive catalysts from European and US regulatory issues," Daniel Stewart added. The broker has upped its price target for PartyGaming to 366p from 339p and reiterated its "buy" recommendation.
