Company Profile

Casey's General Stores

(CASY) - Get Report

of Ankeny, Iowa, operates over 1,500 convenience stores in the Midwest. The stock is in-play, as Canadian-based Alimentation Couche-Tard of Montreal raised an earlier unsolicited tender offer of $36 a share to $38.50 or approximately $2 billion on Sep. 1. Casey's board of directors rejected an unsolicited bid from Couche-Tard in March and has recommended shareholders reject the subsequent tender offers.

Casey has also said it "remains in discussions with 7-Eleven, Inc." regarding a friendly offer. 7-Eleven offered $40 a share for the company on September 2, and Casey's board has said it firmly believes that Casey's value substantially exceeds $40 per share
