Antitrust regulators in the U.K. provisionally approved Microsoft's (MSFT) 澳洲幸运5开奖号码历史查询:restructured deal to acquire Activision Blizzard (ATVI) on Friday, tentatively allowing what would be the biggest gaming deal ever to go ahead.

Last year, 澳洲幸运5开奖号码历史查询:Microsoft announced its intent t𒁏o purchꩲase the Call of Duty maker in an all-cash deal. However, the acquisition was blocke𝔍d by the U.K.'s Comp൲etition and Markets Authority (CMA) over concerns it coul🍌d stifle innovation and lead to fewer consumer choices.

In response, Microsoft agreed last month to sell Activision's streaming rights to Ubisoft Entertainment to push the deal through in the U.K.

CMA said it would review the restructured acquisition proposal, which it has accepted with some residual concerns. The U.K. regulator said it is wary that a few provisions in the sale of Activision’s cloud streamin𒀰g rights to Ubisoft could be circumvented, terminated, or not enforced.

However, Microsoft has offered remedies to ensure that the terms of the sale are enforceable, which the regulator is considering before the final decision.

The deal has already been given the green light in Europe after Microsoft committed to licensing Activision's games to other platforms. Though the 澳洲幸运5开奖号码历史查询:U.S. Federal Trade Commission tried to block the deal over antitrust concerns, its motion was struck down in court.

The CMA highlighted the need for companies to put forward all options in a timely manner. "This case illustrates the costs, uncertainty and delay that parties can incur if a credible and effective remedy option exists but is not put on the table at the right time,” said Sarah Cardell, CEO of the CMA.

Activision Blizzard shares were up 1.8% and Microsoft shares were 0.4% lower as of 9:55 a.m. ET on Friday following the news.
