Check out which companies are making headlines before the bell:
Michael Kors — The luxury goods maker reported quarterly profit of 98 cents per share, beating estimates by 2 cents a share. Revenue was also above forecasts. Same-store sales were up 0.3 percent, matching forecasts, and Kors also announced a $1 billion share buyback.
Nike — The athletic apparel and shoe maker was downgraded to "equal weight" from "overweight" at Morgan Stanley, which said the athletic apparel category is weakening while competition is increasing.
Tesla — CEO Elon Musk told the automaker's annual meeting that Model 3 owners will not receive free and unlimited access to the company's charging station network for life, unless they purchase a specific package. Separately, the automaker said that two upcoming software updates should fix persistent glitches with the futuristic rear doors on its Model X SUV.
Under Armour — The company issued a sales warning directly related to the bankruptcy filing of sporting goods retailer Sports Authority. The sports apparel maker said it would only see about a quarter of the revenue it had originally expected from sales at Sports Authority.
