Erstwhile Market Basket CEO Arthur T. Demoulas has lost his court battle to regain control of the iconic grocery chain.
In a Monday decision, Delaware Court of Chancery Vice Chancellor J. Travis Laster validated Market Basket board members’ vote to remove Demoulas last September — a termination that followed escalating corporate tensions, months of public mudslinging, and two failed mediation sessions.
The long-simmering feud over Market Basket’s leadership and future pitted Demoulas against his three sisters, who control about 61% of the company combined compared to Demoulas’s 28%.
In a statement, the Market Basket board said it “thanks Mr. Demoulas for his many years of service and anticipates working with him productively into the future as one of the company’s important shareholders.”
What does the Market Basket decision say?
In fighting to reverse his termination and regain his job, Demoulas “sought to prove that the directors breached their duty of loyalty by acting in bad faith to benefit his sisters and their families,” Laster wrote. “He failed to carry his burden.”
The judge generally agreed with Market Basket board members who felt Demoulas had snubbed their attempts at oversight and ignored his sisters’ pleas for greater transparency.
“He proved to be an excellent operator, but an imperious leader. Arthur believes in top-down management control and sees little need for board oversight,” Laster wrote, adding, “He viewed himself as the best judge of what served Markets’ best interests, and he believed he had the power to take action without asking for the board’s permission.”
Before firing him, Market Basket’s board placed Demoulas on paid leave amid allegations that he and his allies were planning a work stoppage — a power play similar to the 2014 boycott that won him control of the company during a feud with rival cousins. But after he was sidelined from the family business last May, Demoulas didn’t go down without a fight, Laster noted.
“The CEO escalated,” Laster wrote, citing Demoulas’s full-throated public relations crusade. “Through intermediaries, he launched a social media campaign ridiculing the three directors and his sisters. That effort included a website that posted their personal contact information, resulting in death threats.”
When Market Basket’s board members ultimately voted to fire Demoulas, they likened him to a dictator. That fall, they filed a lawsuit in Delaware — where the chain’s holding company is incorporated — to make his removal official. But in a counterclaim of his own, Demoulas accused board members of acting in bad faith and said they improperly colluded with his sisters.
Laster presided over a brief trial on the matter in December, hearing closing arguments in February.
Arthur T.’s camp reacts
“Arthur T. Demoulas filed his response to the Board’s lawsuit knowing there were high hurdles given the broad latitude Delaware courts give to Boards of Directors,” Demoulas spokesperson Justine Griffin said Monday.
“Market Basket is an incredible success by every measure,” she continued. “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.”
According to Laster, Demoulas “proved that he was a good operator and that the directors did not suspend or terminate him because of problems with the business. That, however, is not the only dimension of a CEO’s job. Nor is it all that directors can consider.”
Following Monday’s decision, Market Basket’s board said it is looking ahead to the company’s next chapter.
“With this behind us, we’re looking forward to continuing to focus on everything that makes Market Basket so important to our communities,” the board’s statement read. “Market Basket will continue to be a family-owned and operated business, offering the lowest prices and best value for customers, creating good jobs with profit sharing for associates, and supporting its customers and communities — well into the future.”
