iFit Health & Fitness, the U.S. connected fitness company, has formally withdrawn its registration statement for an initial public offering, a plan it suspended last fall, citing difficult market conditions. The company applied to the U.S. Securities and Exchange Commission (SEC) for a credit for registration fees paid. A month ago, iFiT, parent of the NordicTrack, Weider and ProForm fitness brands, among others, raised $355 million in capital from L. Catterton, the largest global consumer-focused private equity firm.
