Leading retailer of teenage apparel, Aeropostale Inc, on Wednesday posted a first-quarter profit of $592,000 on the back of a 50 per cent surge in sales and said May sales climbed almost 50 per cent as well.

The New York-based operator of more than 307 stores, which had a hugely successful IPO last month, said that profit compared to a $2m net loss in 2001 and said net sales soared to $85.1m partly thanks to 58 new stores.
