The Houston-based company, which makes branded names including Goodman, Amana, Janitrol, and QuietFlex, is controlled by the investment firm of Apollo Management LP and its affiliates, which gained majority ownership in November 2004 and now holds about 68 percent of the company's common stock. Goodman family trusts control 21.1 percent.
In IPO documents filed in February with the Securities and Exchange Commission, Goodman said there are "areas of opportunity and elements of potential risk."
