Chidsey, the first chief executive outside of the chain’s founding family, joined Subway as CEO in 2019. His departure marks another entry on the list of fast food chain CEOs who have stepped down this year for a variety of reasons, including Starbucks, Chipotle, Shake Shack, and Wendy’s.

The sandwich chain named current executive Carrie Walsh interim CEO as it conducts a search for a permanent successor.

The 62-year-old will stay on as a consultant at Subway to help with international expansion, according to a report.
