Ari Emanuel’s live events company Mari Group is reportedly in talks to acquire major theater owner ATG Entertainment. 

According to a report in the Financial Times, Mari Group is in advanced talks with private equity firm Providence, which owns ATG, to acquire the theater group. The paper pegs the total deal size at $6 billion, citing four people familiar with the matter, with the hope of closing the deal within the next month.

Representatives for Mari, Providence and ATG did not respond to requests for comment. 

ATG has 10 theaters on the West End, including the Lyceum, home to long-running hit The Lion King and the Savoy Theatre, where the box office hit Paddington the Musical is playing. It has seven Broadway theaters, after acquiring a majority stake in Jujamcyn Theaters in 2023, as well as the Lyric Theatre, which is home to Harry Potter and the Cursed Child. In total, the company owns, operates or programs 70 venues across Britain, the U.S., Germany, Austria and Spain.

The theater group, which also has a producing arm, has been owned by private equity firm Providence since 2013. 

The Mari Group already has a presence in the theater world, after acquiring ticketing company TodayTix in October 2025, just weeks after launching his company. The portfolio also includes the Miami Open, Madrid Open, Frieze art fairs and car auction company Barrett Jackson. Emanuel is also CEO of TKO, home to the WWE and UFC, and executive chairman of WME Group.
