Amazon has tapped Whole Foods CEO Jason Buechel to oversee its sprawling grocery business, the company announced Monday.

Doug Herrington, the company’s worldwide retail chief, wrote in a memo to employees posted to Amazon’s site that Buechel will “take on an expanded responsibility leading Worldwide Grocery Stores” while continuing to lead Whole Foods. Amazon acquired the upscale grocer for $13.7 billion in 2017.

“In his time as CEO, Jason has unlocked our ability to make high-quality natural and organic groceries more affordable and accessible to customers, helping WFM achieve record sales growth and expand to over 535 locations,” Herrington said.

Buechel became CEO of Whole Foods in 2022 after co-founder John Mackey retired from the company. In his expanded role leading Amazon’s grocery business, Buechel will succeed Tony Hoggett, who left Amazon last October to join Wondery, a food delivery startup led by serial entrepreneur Marc Lore.
