Consumers and Redner’s Markets have alleged that Lamb Weston and other frozen-potato producers coordinated price increases and shared sensitive information, including through a data service. In September 2026, a federal judge declined to dismiss core antitrust claims. Lamb Weston denied the allegations, said it would vigorously defend itself, and stated it competes fairly.
Lamb Weston Holdings Inc. and Cavendish Farms Inc. are among a group of food companies hit with a proposed class action alleging they colluded to fix and raise the price of frozen potatoes with help from a data aggregation service.
Cavendish Farms Inc., Lamb Weston Holdings Inc., and other food manufacturers fell short in their bid to shake antitrust claims that they exchanged competitively sensitive data to fix prices for frozen potato products through an unlawful multiyear agreement.
The lawsuit, brought by Redner’s Markets, an employee-owned supermarket chain based in Pennsylvania, on behalf of itself and others, accuses the companies of illegally coordinating an effort to implement lockstep price increases since at least 2021 in violation of the Sherman Act, a federal law that prohibits anticompetitive agreements and conduct that monopolizes or attempts to monopolize a certain market.
The four companies controlling roughly 98% of the frozen potato product market must face consumers' accusations that they shared competitively sensitive information and coordinated other efforts to carry out an illegal price-fixing scheme, an Illinois federal judge has ruled.
