Shares of a major retailer fell after it reported sluggish sales growth. The company's sales at existing stores rose, but at a slower pace than in recent quarters. Online sales tied to those locations were also included in this measure.

A specific category, including pharmacies, was affected by federal pricing rules, which had a negative impact on sales. As a result, the increase was lower than expected. The retailer's outlook for the year was cautious, leading to a decline in its shares.
