GNC ends 2016 as worst year since IPO

New York

GNC Holdings limped to the finish of its worst year since it went public in 2011, and the vitamin retailer is leaving shareholders with little to get excited about in the next 12 months.

The company's shares have plunged by more than 64 per cent in 2016 as foot traffic fell at its more than 4,400 US stores, and customers cut down on buying vitamins and nutritional supplements.
