Overview
- Arthur T. Demoulas chose not to file an appeal after the court ruling, effectively closing the Delaware litigation over his suspension and firing.
- The Court of Chancery found the board acted within its authority under Market Basket’s bylaws and said Mr. Demoulas would have needed to prove directors acted in bad faith to prevail.
- The board suspended Demoulas in May 2025 over concerns about a possible work stoppage and then fired him in September 2025, moves the court upheld.
- Demoulas retains a 28 percent economic stake while his three sisters control roughly 60 percent of the company, a split that leaves open the possibility of future family disputes outside court.
- Board lawyers say the decision lets executives concentrate on day‑to‑day operations for the chain’s roughly 90 stores and 30,000 employees, but customers and staff remain a sensitive factor because the board cited the disruptive 2014 walkout when defending its actions.
