Under Armour Quietly Accumulating Quite An Athlete Porfolio

On Sunday, Jordan Spieth became just the sixth golfer to win both the Masters and the U.S. Open in the same year. However, the 21-year-old Texan was not the only winner at Chambers Bay this weekend. Spieth’s success so far this year has served to further solidify the all-star roster of pro-athlete endorsers that Under Armour Inc UA currently has under contract.

The Under Armour roster
Not only does Under Armour have an endorsement contract with the 2015 Masters and U.S. Open golf champion, it also has NBA MVP and world champion Steph Curry on its team. Now that the U.S. Open and the NBA Finals are over, much of the attention in the sports world will shift to baseball, where reigning 2014 Cy Young winner Clayton Kershaw and leading 2015 MVP candidate Bryce Harper are both under contract with Under Armour.

Once NFL football season rolls back around, attention will shift to Superbowl champion quarterback Tom Brady, also an Under Armour endorser.

The competition
Despite the recent success of Under Armour’s athlete endorsers, competitor Nike Inc NKE remains the gold standard in the sports world when it comes to athlete endorsements. In addition to the most iconic basketball player of all time, Michael Jordan, Nike also has endorsement deals with LeBron James, Kobe Bryant and Kevin Durant.

When it comes to golf, Under Armour may have Spieth, but Nike has deals with Tiger Woods and Rory McElroy.

On the diamond, Nike has deals with 2014 MVP Mike Trout, Yankee legend Derek Jeter and former MVP Albert Pujols.

Stock performance
So far this year, the success of Under Armour’s athlete endorsers has been reflected in the company’s share price. Under Armour has surged 24.2 percent in 2015, more than doubling Nike’s 11.2 percent return year-to-date.
