I think it's "Carl's Jr"...lemme check...yes.
Carl's Jr and Hardee's were created independently in different markets. But they were merged and intentionally made to look more alike:
In April 1997, CKE Restaurants Holdings, Inc., the parent company of Carl's Jr., paid $327 million to Montreal-based Imasco Limited for Hardee's.[2] The merger created a chain of 3,828 restaurants – 3,152 Hardee's outlets in 40 states and 10 foreign countries and 676 Carl's Jr. outlets, primarily in California. In June 2018, former CKE CEO Jason Marker announced that Carl's Jr. and Hardee's would become separate brands, claiming that CKE's racy advertising and marketing campaigns were incompatible with a family-oriented chain like Hardee's.[3] In April 2019, Ned Lyerly, a 30-year veteran of the company and formerly president of CKE's International division, was named CEO, replacing Jason Marker.
