Speith tied for fourth at the British Open.

The company also counts football's Tom Brady, ballerina Misty Copeland, and Stephen Curry as its sponsees.

With today's release, UA COO/CFO Brad Dickerson commented, The ongoing strength of our Brand and execution of our business plan give us confidence in raising our full year top line outlook. In addition, the confluence of our sports marketing success stories has provided a unique opportunity to drive investment toward areas that we see are key to long-term sustainable growth and we plan to take advantage of this dynamic in the back half of 2015. At the same time, we are increasing our focus on developing sustainable business process improvements and better connecting the components of our value chain to more fully capitalize on our Brand's momentum each season going forward. We look forward to discussing these initiatives and our longer-term business plan in greater detail at our Investor Day on September 16th.
