Wendy's US operations are melting like one of the chain's trademark Frosties on a hot summer day. The burger giant said Friday it plans to close as many as 350 US locations amid declining sales and profitability. Full-year, system-wide US sales fell 5.2% in 2025, with same-restaurant sales down 5.6% year over year. "We're executing Project Fresh with urgency to strengthen our foundation and position Wendy's for long-term success," interim CEO Ken Cook said in a statement, referring to the company's turnaround plan.
