In 1997, the chain was acquired by CKE Restaurants, the parent company of the Carl's Jr. fast-food restaurant chain. (Imasco retained the few remaining Roy Rogers locations, though CKE is reported to do some supplying of them). Over time, some Hardee's restaurants were converted to serve higher-quality hamburgers and other products available from Carl's Jr., and also took on the Carl's Jr. star logo in the process. Some locations were simply fully-rebranded Carl's Jr., this was a year after Wendy's and Tim Hortons purchased most of the Hardee's stores in Michigan.
