Nike says it's facing an increasingly challenged environment where sell-through remains under pressure. Sales edged down in the latest quarter, dragged down by a particularly steep decline in China. Still, the company says its results were in line with its expectations, and it pointed to some bright spots in its performance offerings. "While we continue to face top-line headwinds, we're encouraged by progress in performance product and are focused on consistent execution, improved profitability and scaling our wins to realize our full potential," CEO Elliott Hill says.
