| Amendment Description | On November 23, 2020, Cracker Barrel Old Country Store, Inc. (the “Company”) filed a Current Report on Form 8-K (the “Original Form 8-K”) with the Securities and Exchange Commission to report, among other things, the final voting results from its 2020 annual meeting of shareholders, held on November 19, 2020 (the “Annual Meeting”). The sole purpose of this Amendment No. 1 to Current Report on Form 8-K/A (“Amendment No. 1”) is to delete a footnote with respect to the vote totals for proposal 1, the election of directors at the Annual Meeting, that was inadvertently and erroneously included in the Original Form 8-K. For purposes of clarity, this Amendment No. 1 amends and restates Item 5.07 of the Original Form 8-K in its entirety. There is no other amendment to the Original Form 8-K or its exhibits made by this Amendment No. 1. |
