Analysts had forecast earnings of 98 cents per share on revenue of $741 million. The company, which operates membership-style shopping clubs, said the devaluation of the Colombian peso contributed to a 16-cent hit to its earnings per share.
Apparel retailer Gap, whose brands include Old Navy, Banana Republic and its namesake chain, said overall same-store sales rose 2 percent in March, compared to an expected rise of 1 percent, according to Consensus Metrix.
However, Gap said the earlier timing of the Easter holiday will "likely negatively impact its April sales results." The stock fell about 2 percent after the announcement.
Restaurant operator Ruby Tuesday reported a narrower-than expected quarterly loss of a penny a share on revenue of $286 million, which was in line with expectations. Wall Street projections called for a loss of 4 cents a share. Shares rose about 2 percent in extended trading.
