Update: F45 made its public debut Thursday. Shares opened at $17 and closed at $16.20, giving F45 a market value of $1.46 billion.

F45 (PRIVATE:F45TRAINING) is going public. On Wednesday, the fitness chain, which counts Mark Wahlberg among its investors, rolled out information about its upcoming IPO. The Australian fitness chain, whose name comes from its “functional 45-minute” workouts, is setting its sights on a $15-$17 share price range, which would value the company at up to $1.5 billion.

Wahlberg’s stake could be worth up to $15 million, depending on the offering price and how many shares end up being listed. The actor first joined as an investor, when the Mark Wahlberg Investment Group (MWIG) bought a minority stake, and has served on the board of directors for the past two years. Wahlberg has his own F45 franchise on the Marine Corps Air Station (MCAS) Miramar in San Diego.

In addition to Wahlberg, F45’s S-1 boasts “relationships” with other celebrities and athletes like David Beckham, Magic Johnson, and Cindy Crawford. 

F45 was founded in 2011 by Rob Deutsch as a personalized approach to the gym, featuring at-home workout programs as well as a series of franchised locations. Deutsch opened the first F45 location in Sydney in 2012, but stepped down as CEO and left the company in 2020 amid stalled IPO plans. 

As gyms shuttered their doors during the pandemic, companies specializing in at-home workouts took off. F45 saw decreased revenue and net losses in both 2020 and Q1 2021, according to their revised S-1.
