(1) Under Armour, Inc. declared a stock dividend pursuant to which all holders of Class A Common Stock on March 28, 2016, the record date for the dividend, received on April 7, 2016, one share of Class C Common Stock for each share of Class A Common Stock held by them as of the record date (the "Class C Dividend"). The holdings in column 5 include shares of Class C Common Stock received by the Reporting Person pursuant to the Class C Dividend, including outstanding shares held by the Reporting Person and shares underlying deferred stock units previously granted to the Reporting Person.
(2) This stock option was originally reported as an option to purchase 2,100 shares of Under Armour, Inc.'s Class A Common Stock at an exercise price of $35.70, 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 8,400 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 $4.4937 and the portion of the option covering the Class C Common Stock has an exercise price of $4.4313 per share.
(3) This transaction was executed in multiple trades at prices ranging from $44.11 to $44.20. The price reported above reflects the weighted average sale price. The reporting person hereby undertakes to provide upon request to the SEC staff, the issuer or a security holder of the issuer full information regarding the number of shares and prices at which the transaction was effected.

Does not include Class A Common Stock held by the reporting person.
