The Cincinnati company's results come just days after the abrupt resignation of long-time Chief Executive Officer and Chairman Rodney McMullen over personal conduct. They're also the first since a federal judge blocked a $20 billion deal to takeover smaller rival Albertsons.

Kroger’s total company sales were $34.3 billion in the fourth quarter compared to $37.1 billion for the same period last year.

Mr. McMullen’s conduct is not related to the company’s financial performance, operations or reporting, and it did not involve any Kroger associates,” the company said.
