According to an internal memo sent to employees today, Wexler is departing the brand on Aug. 31 to pursue interests outside of the company. Further specifics regarding the exit weren't announced.
"Jon, also known by many as 'Wex,' joined Adidas in 2000 and quickly developed through a number of positions in Brand Communications and EIM," the memo says. "Most recently he successfully led the Yeezy [business unit]. Over the last two decades, Wex has made significant contributions to the Adidas brand through establishing partnerships with creators such as Kanye West, Pharrell, and Beyonce, to name a few."
Wexler's tenure with the Three Stripes started when he became the brand's category manager in 2000 before leaving for Converse in '04 to become director of lifestyle marketing. He rejoined Adidas in 2006 as brand manager, eventually working his way up to become the VP of global entertainment and influencer marketing, and then was named GM of the Yeezy line late last year.
UPDATE: Wexler has issued his own statement on his departure from the brand: "My (combined) 18 years at [Adidas] have been the heart of my career. As my role at Adidas evolved, I tried to help the brand grow via innovative partnerships and transformative collaborations with the world’s most prolific creatives. From the people who gave me my first opportunity here, to all of the incredible people I've had the pleasure of working with along the way, there are too many of you to thank - but know that I am deeply grateful for every one of you. I leave the brand with nothing but [love] for Adidas and the entire extended Adidas family. Very excited for what the next chapter will bring!"
