Casey’s General Stores Inc. announced Thursday that it has closed on its previously announced $220 million acquisition of 40 stores from Pilot Corp. The Ankeny-based convenience store chain said the acquisition gives Casey’s immediate scale in the attractive Knoxville, Tenn., market and is part of the implementation of its three-year strategic plan that was shared in January 2020 when the company set a three-year goal of adding 345 stores to its chain. “We are pleased to complete this transaction and expand our footprint in Tennessee and Kentucky,” said Darren Rebelez, president and CEO of Casey’s. “The Haslam family and the Pilot team have been great to work with and we look forward to welcoming team members to Casey’s and bringing our handmade pizza program to these excellent stores.”
