Under Armour CEO Kevin Plank said his company still has plenty of room to grow, despite concerns about the company's slowing sales.
"We have eyes on number one. We are one of the top three brands in the world and, more importantly, we have eyes on being the number one brand in the world, and that's the kind of company you're investing in," Plank said in an interview with CNBC's Scott Wapner on "Halftime Report" on Wednesday.
On Tuesday, Under Armour's Class A shares saw their worst daily performance since Nov. 12, 2008, amid concerns that the company is losing steam, especially in its biggest market, North America. The stock continued to slide more than 2 percent on Wednesday, following downgrades at a number of research firms.
The athletic apparel company saw third-quarter sales of $1.47 billion, above analyst expectations for $1.45 billion, according to a Thomson Reuters consensus estimate. While that figure was up 22 percent from the year-ago period, it was Under Armour's slowest sales growth rate since the third quarter of 2010.
