(1)	This stock option was originally reported as an option to purchase 3,061 shares of Under Armour, Inc.'s Class A Common Stock at an exercise price of $24.50, and was later adjusted for two separate two-for-one stock splits completed in 2012 and 2014. As a result of the Class C Dividend, the option was further adjusted such that it now entitles the Reporting Person to exercise a portion of the option for 12,330 shares of Class C Common Stock, and the exercise price has been adjusted so that the portion of the option covering the Class A Common Stock now has an exercise price of $3.0839 and the portion of the option covering the Class C Common Stock has an exercise price of $3.02 per share.
(2)	Represents shares withheld to cover the exercise price of the options exercised.
