Kroger upgraded its full-year profit prediction on Thursday, supported by continued grocery demand as the pandemic-induced boom in at-home cooking continues, sending shares up 4% in premarket activity.

An increase in COVID-19 cases in the United States boosted retailer sales in the third quarter, forcing some, such as Costco Wholesale, to reintroduce purchase limitations on commodities like tissues, paper towels, and bottled water as consumers resumed stockpiling supplies.

Kroger predicts adjusted profits per share of $3.40 to $3.50 for the full year, up from $3.25 to $3.35 before.

The company forecasted a 0.2 % to 0.4 % drop in full-year same-store sales, down from its previous prediction of a 1% to 1.5% drop.
