Under Armour's current CEO (as of 2023) is which former Marriott executive?

As of 2023, Under Armour’s CEO was Stephanie Linnartz, the former president of Marriott International. She became Under Armour’s president and chief executive officer on February 27, 2023, after spending 25 years rising through Marriott’s leadership ranks.

Linnartz joined Marriott in 1997 as a financial analyst and later held roles spanning finance, revenue management, sales, marketing, technology, digital operations, and customer loyalty. She became Marriott’s president in 2021 before leaving the hospitality company for Under Armour.

Her appointment represented a deliberate effort to bring an outsider with experience in e-commerce, branding, digital transformation, and loyalty programs to the sportswear business. Under Armour’s founder, Kevin Plank, remained executive chair and brand chief during Linnartz’s tenure.

The date qualifier matters. Linnartz was no longer Under Armour’s CEO after April 1, 2024, when Kevin Plank returned to the role. Thus, Stephanie Linnartz is the correct answer for the question’s stated 2023 timeframe, but not for a question asking who leads Under Armour today.
