Casey’s General Stores, Ankeny, Iowa, in November agreed to acquire Buchanan Energy, owner of Bucky’s Convenience Stores, for $580 million. The Omaha, Neb.-based company operates 94 retail sites in five Midwestern states, as well as 79 dealer locations. The FTC delayed the closing over anticompetitive concerns, requiring the sale of three Casey’s stores and three Bucky’s locations. The deal finally closed May 14.
