Over the past few months, investors grew concerned that Under Armour was beginning to lose some of its momentum in the U.S., as warm weather forced it to take markdowns on some of its apparel.
But growth outside of the clothing category — namely, the company's 95 percent revenue growth in footwear during the quarter — and overseas expansion helped mitigate the discounts. The company is also putting more emphasis on expanding its women's division, and outlined the potential to significantly expand its presence at branded and sporting goods stores.
Whereas Under Amour's "largest competitor in North America" has 24,000 points of distribution, it has just 11,000, Plank said.
"We are just getting started," he said.
The company will need those additional levers to continue driving growth. Comparisons will get decidedly tougher for Under Armour in 2016, after posting 23 straight quarters of more than 20 percent top-line growth.
