Warner Music Group has been sold to Len Blavatnik and his Access Industries for $3.3 billion in an all-cash transaction. The meeting to choose the winner of Warner was held yesterday with the official announcement dropping today. After the close, WMG will become a privately held company with no stocks traded on the New York Stock Exchange, but it will remain in its current space and keep its Warner Music Group name.

WMG’s chairman and CEO, Edgar Bronfman Jr., said in a press release that he viewed the buy as an “exceptional value-maximizing opportunity that serves the best interests of stockholders as well as the best interests of music fans, our recording artists and songwriters, and the wonderful people of this company.” WMG is home to a wide range of artists, from Green Day to T.I. and plenty in between.
