Costco–Costco reported quarterly earnings of $1.17 per share, 2 cents above estimates, though revenue and comparable store sales were below forecasts. The warehouse retailer was hurt by lower gasoline prices and a stronger dollar.
Express–The apparel retailer reported adjusted quarterly profit of 22 cents per share, seven cents above estimates. A comparable store sales increase of seven percent helped push revenue above analyst forecasts, and Express has now raised its full year guidance.
