Teen retailers Aeropostale undefined and American Eagle Outfitters undefined each lifted first-quarter earnings guidance after April same-store sales results came in higher than expected Wednesday. New York-based Aeropostale now expects to earn 9 cents a share in the first quarter, up from a prior estimate of 7 cents a share, which is also the Wall Street consensus. (The company had a 3-for-2 stock split on April 26, which affected its prior earnings guidance. Before the split, the company had expected to earn 11 cents a share.) Aeropostale posted a 19.3% spike in April same-store sales -- well above an 8% increase in the same period of 2003 -- and a 18.9% increase in first-quarter same-store sales. In the first-quarter of 2003, same-stores sales rose 1.8%. Analysts polled by Thomson First Call were expecting a 9% increase in Aeropostale's April same-store sales, on average.
