Life Time, the Chanhassen-based operator of upscale health clubs that went private in a 2015 buyout by its founder, is going to become a publicly traded company again.
Life Time Group Holdings Inc. filed an S1 document with securities regulators on Monday for an initial public offering.
The filing didn't indicate how many shares were to be sold or at what price but did indicate that Life Time will be considered a "controlled company" after the offering, meaning that existing shareholders will own more than 50% of outstanding shares.
The filing didn't specify how much money the company aims to raise. According to the filing fee it paid, Life Time could be seeking approximately $100 million. The date of the listing will depend on market conditions and could be weeks or months away.
Company founder and chief executive Bahram Akradi took the company private in 2015 in a $4 billion deal that also involved private-equity firms Leonard Green & Partners, TPG and LNK Partners. Akradi and those firms would remain the major shareholders after the IPO.
A Life Time representative declined to comment on the filing, citing regulators' restrictions.

When the company went private, it had approximately 114 fitness centers and annual revenue of $1.3 billion. Since then, it increased the number of fitness centers to more than 150 in 29 states and Canada.
Revenue increased to $1.9 billion in 2019, but it fell sharply last year to $948 million due to closures to stop the spread of COVID-19.
