Select Medical Holdings, a leading operator of specialty hospitals and outpatient rehabilitation clinics, filed with the SEC for an IPO on Friday. The holding company was created in 2005 when an investor group led by private equity firm Welsh, Carson, Anderson & Stowe acquired Select Medical, which had originally gone public in 2001. Morgan Stanley, Merrill Lynch and Goldman Sachs are set to be the lead underwriters on the deal. No terms were disclosed in the initial filing.
