The Related Companies

Equinox is a luxury fitness company headquartered in New York City. As of my last update, it was a subsidiary of The Related Companies, a large American real estate firm. Stephen M. Ross, the founder of The Related Companies, was a significant figure in the ownership of Equinox. However, ownership details can change, and there may have been developments since my last update. For the most current information, a search of recent news or the company’s official website would be advisable.
