0659 GMT [Dow Jones] Shore Capital upgrades PartyGaming (PRTY.LN) to hold from sell following the announcement of its plan to merge with Bwin (BWIN.VI). This deal is highly attractive and could provide significant future earnings accretion, says Shore. However, there remains some transaction risk and the shares may drift post this announcement until completion, thus the hold rating rather than a buy, says Shore. Still, the merger is transformation not only for PartyGaming, but the industry as a whole, says Shore. Shares closed Thursday at 309.5p.
