"Since joining us in 2010, Henry has been an incredible partner and helped us build our brand and tell our story. First through his leadership in Apparel, then by heading up our North America business, and most recently by driving merchandising of our products throughout the world. I would like to thank Henry for his strong leadership and contributions over the years", stated Kevin Plank, Under Armour's Founder and Chief Executive Officer.

Kip Fulks will assume the Chief Merchandising Officer responsibilities on an interim basis, including oversight of product, innovation and merchandising.
