Amid rumors last month that Planet Fitness was close to a deal with a private equity firm, CEO Mike Grondahl pointed out that his company has been close to “the finish line” before when it comes to these types of transactions.

Indeed, in 2010, Planet Fitness, Newington, NH, proposed a minority sale with Goode Partners, New York, until that deal fell through. This time around, Grondahl tells Club Industry that he feels good about his company’s possible purchaser, the name of which he did not disclose. One source says that the company is a consumer-oriented private equity firm.

Should the Planet Fitness deal become finalized, it would be the second transaction between a franchised company and a private equity firm this year. Curves International, Waco, TX, completed a deal with private equity firm North Castle Partners, Greenwich, CT, in August. Terms of that deal were not disclosed.

With markets opening during the past year, private equity firms are becoming more interested in the fitness industry. Industry insiders say that the industry’s recession-resilient reputation, increased mergers and acquisitions in the industry, plus an impending capital gains tax deadline have led to more activity as 2012 heads down the home stretch.
