Revenue edged up 1 percent to $13.77 billion from $13.6 billion in the prior year. Analysts expected $13.69 billion.
Revenue was helped by higher prepaid and gift card sales. Revenue in stores open at least one year, a key retail metric, rose 0.8 percent, hurt by a customer shift to generic drugs.
For the year, net income rose 15 percent to $596.5 million, or $2.41 per share. That compares with $516.7 million, or $1.49 per share in the prior year. Revenue rose 1 percent to $44.21 billion from $43.63 billion in the prior year.
The company did not give specific guidance but CEO Burd said eight weeks into the quarter revenue in stores open at least one year is up 2 percent, so that figure could be up 1.8 percent to 2 percent in the quarter.
"As Just for U matures, and as the fuel and wellness initiatives are rolled out, we feel our volume, our market share, and our (revenue in stores open at least one year) should only continue to improve," he said.
The company plans to give detailed guidance at an investor event on March 6.
