What Happened to Demoulas Family Feud?

The Demoulas Family Feud traces its origins back to the founding of Demoulas Market in Lowell, Massachusetts, in 1917 by Greek immigrants Athanasios and Efrosini Demoulas. The business was later taken over by their sons, Mike and George Demoulas, who expanded it into a supermarket chain. The initial seeds of conflict were sown after George Demoulas's death in 1971, when his widow and children, including Arthur S. Demoulas, alleged that Mike Demoulas had defrauded them out of their rightful shares in the company by diverting assets to entities he solely controlled, such as the Market Basket chain.

This led to a protracted legal battle in the 1990s, culminating in a 1994 court ruling that awarded George's family 50.5% ownership of Demoulas Super Markets and approximately $206 million in diverted dividends. Despite this, Mike Demoulas's son, Arthur T. Demoulas, eventually rose through the ranks, becoming CEO in 2008. Under his leadership, Market Basket experienced significant growth, expanding its sales and employee base, and fostering a strong culture of employee loyalty through generous wages, benefits, and profit-sharing.

The feud dramatically re-erupted in June 2014 when the board of directors, then controlled by Arthur S. Demoulas's side of the family, fired Arthur T. Demoulas. This decision triggered an unprecedented wave of protests from thousands of loyal employees, including warehouse workers and truck drivers, who walked off the job. Customers joined in with boycotts, leaving store shelves bare and severely impacting the company's sales. The public pressure, coupled with mediation efforts by state governors, ultimately forced a resolution. In August 2014, Arthur T. Demoulas, along with his sisters, successfully purchased the 50.5% stake owned by Arthur S.'s family for $1.5 billion, leading to his reinstatement as CEO and ending the immediate crisis.

However, the family discord was far from over. In May 2025, Arthur T. Demoulas was again suspended by the board, which was now controlled by his three sisters (Frances Demoulas Kettenbach, Glorianne Demoulas Farnham, and Caren Demoulas Pasquale), who collectively held a 60% stake in the company. The board cited allegations of Arthur T. planning a work stoppage in retaliation for requests for greater collaboration and oversight. Arthur T. denied these claims, calling them a "farcical cover for a hostile takeover." After mediation failed, he was officially fired in September 2025.

The legal battle moved to the Delaware Court of Chancery, where Arthur T. filed a lawsuit seeking his reinstatement. In a significant ruling on April 20, 2026, Judge J. Travis Laster upheld the board's decision to fire Arthur T. Demoulas. The judge found that Demoulas had failed to prove the board acted in bad faith, noting his "longstanding resistance to board oversight, imperious manner, and refusal to compromise with his sisters threatened the company." The court also agreed that the board had reasonable suspicion he might plan another employee walkout.

As of September 5, 2026, Arthur T. Demoulas remains out of his CEO role. Following the court's decision, Market Basket announced management changes in late April 2026, with Donald T. Mulligan retiring as interim CEO and Chuck Casassa, a 50-year company veteran, being named President. Speculation has also arisen regarding Michael Kettenbach Jr., Arthur T.'s nephew and son of Frances Demoulas Kettenbach, who was named Director of Operations in June 2026, as a potential future leader. The company continues to operate with 90 locations across New England and reported revenues of $7.3 billion in 2024, growing to an estimated $8 billion by 2026.
