NEW YORK (Reuters) - Teen apparel retailer American Eagle Outfitters Inc <AEO.N> said on Wednesday quarterly net profit fell, hurt by greater markdowns resulting from lower-than-expected sales.

The mall-based chain, known for colorful, casual fashions, said net profit in the first quarter was $43.9 million, or 21 cents per share, compared with $78.8 million, or 35 cents per share a year earlier.
