An Iowa-based convenience store chain has completed the purchase of 40 stores from Knoxville, Tennessee-based Pilot Corporation.

Casey’s General Stores, Inc. announced in a news release that it had closed the sale as part of a three-year strategic plan to add 345 new stores nationwide.

The company describes itself as the third-largest convenience store retailer in the United States, with more than 2,400 stores nationwide.

Casey’s says the purchase will expand its footprint in Tennessee and Kentucky.

The Knoxville News Sentinel reported that the Haslam family, which owns a controlling share of Pilot, intends to get out of the convenience store business, while still maintaining some travel centers.
