Under Armour Names Marriott International Veteran Stephanie Linnartz as President, CEO

Baltimore-based athletic powerhouse Under Armour, Inc. has appointed Stephanie Linnartz as president, chief executive officer, and member of its board of directors, effective February 27, 2023.

Linnartz has served as president of Marriott International, Inc. since 2021.

Commenting on her new role, Linnartz said, “Under Armour is an iconic brand with a huge opportunity ahead. This company has immense energy and excitement, and I am committed to building growth while maintaining operational excellence.”

With the arrival of Linnartz, president and CEO Colin Browne, who has been in the role since June, will resume his position as chief operating officer.

The announcement comes seven months after Under Armour revealed Patrik Frisk, who took over as president and CEO in January 2020, was stepping down from the role and as a member of its board of directors. Frisk joined Under Armour in June 2017 as president and COO, and later added CEO to his title after Plank announced he was stepping down from the role.

“As a 25-year veteran of one of the world’s most respected global companies, we are thrilled to welcome Stephanie to the brand,” said Kevin Plank, Under Armour executive chair and brand chief.
