Activision Blizzard Inc. shares rose more than 6% Friday morning after the U.K’s Competition and Markets Authority said that it was narrowing its concerns about the company’s possible acquisition by Microsoft Corp.

In a Friday release, the U.K. regulator said it had “received significant new evidence” in response to its initial provisional findings.

“Having reviewed the additional evidence, we have now provisionally concluded the merger will not result a substantial decrease in competition in console gaming services.” Martin Coleman, chair of an independent panel of experts, said that the cost to Microsoft of withholding Call of Duty would outweigh any benefits from such action.

Activision shares , +4.89% , up 6.4% on Friday morning action, are on track to record their largest single-day percentage gains since Jan. 18, 2022 when they rose 25.9% on day of Microsoft MSFT’s, +0.23% announcement. Stocks have recently traded above $84, and are on track for closing at their highest level since the announcement. Microsoft paid $95 per share for the deal.

CMA stated that the new evidence “provisionally eases concerns” about gaming consoles in the U.K, but does not change the authority’s previous concerns about the market for cloud-gaming.

The investigation will be completed by April end.
