Market Basket’s Board of Directors has officially replaced former CEO Arthur T. Demoulas with a new chief executive, reports say.

The longtime CEO, Demoulas, was fired from Market Basket in spring 2025, in what he called a ‘hostile takeover.’ After almost a year of battling in courts, a Delaware judge sided against Demoulas last week, paving the way for the new CEO to be appointed.

Market Basket’s new CEO is Chuck Casassa, a senior Market Basket store manager.

Who is Chuck Casassa?

Casassa is Market Basket’s new CEO as appointed by the grocery store chain’s Board of Directors, a decision that was announced April 30, 2026. He started working at the grocery store when he was 14 in 1975 as a bagger, and has climbed the ranks from there.

Market Basket is known for a policy of internal promotions.

Casassa met Demoulas during one of the CEO’s surprise visits to the store in 2025, about a year after dispute over control of the family-owned company has led to a boycott. He was the store manager of the Seabrook location.

“He immerses himself in the business,” Casassa told reporters at the time. “He’s a hands-on executive. He’ll get a good grasp of what’s happening at the store by coming here like this.”

The Providence Journal reached out to Arthur T. Demoulas’ spokesperson about his CEO replacement and did not recieve a response ahead of publishing. However, Demoulas did release a statement after the judge’s opinion to uphold his replacement last week.

“Market Basket is an incredible success by every measure,” Arthur T. Demoulas’ spokesperson said. “As his father before him, the late Telemachus A. Demoulas, Arthur T. has devoted his entire working life to building and growing Market Basket in a way that has brought benefit to all stakeholders – its Associates, its customers, the communities that Market Basket serves, and its shareholders.”
