So what

Kroger reported fourth-quarter net sales of $28.1 billion, down 9.5% year over year. But when excluding sales from fuel, an extra week in the fourth quarter of 2017, the company's divestiture of its convenience store unit, and the impact of Kroger's merger with Home Chef, sales were up 1.6% year over year. The quarter's sales, however, were shy of analysts' average forecast for $28.4 billion. 

Adjusted earnings per share for the period were $0.48, down from $0.54 in the year-ago quarter. Management noted that 2018 was "an investment year" for the company as it attempts to evolve in a rapidly changing environment -- particularly when it comes to digital sales.
