By April 15, 26 Michigan Burger King outlets, mostly in Detroit, will close.
Burger King franchisee EYM King of Michigan says it failed to negotiate an agreement with the fast-food behemoth.
EYM said that 424 Burger King workers would lose their employment.
Due to a failed contract with Burger King, Michigan franchisee EYM King is shutting all 26 sites.
The Texas franchisee's WARN notification with Michigan's Department of Labor and Economic Development cited a "unforeseen business event" for its closure.
424 employees—including general managers and shift managers—will lose their employment due to shop closures.
EYM started closing Burger King stores on March 17 and plans to close all by mid-April. Most Burger King closures will affect Detroit.
"This locations team will miss the client connections we have formed, it was a joy serving you," reads a sign at 34835 Plymouth Road in Livonia, Michigan, which closed. EYM stated another franchisee may take over Burger King.
About two dozen Michigan Burger King stores are closing as Restaurant Brands International rebrands it. In September, Burger King said it will invest $400 million over two years to expand in the US and establish its premium fast-food reputation. Burger King revamps its top 800 locations.
