Casual apparel chain American Eagle Outfitters Inc on Thursday revealed a 20 per cent slide in second quarter profit from the year-ago period and said early August same-store sales were weak.

The Pennsylvania-based operator of around 900 stores reported earnings in the quarter ended August 2 of $8.1 million, or 11 cents per share, versus $10.1m, or 14 cents per share, in the same period of last year.

Total sales rose 5.6 per cent to $337.1m from $319.2m including $19.3m from its Bluenotes/Thriftys operation in Canada compared to $18.8m last year.

Same-store sales for the American Eagle Outfitters stores fell 5.3 per cent while consolidated same-store sales dropped 5.5 per cent.

Comparable store sales for the American Eagle Outfitters stores through the first ten days of August have declined eight per cent,” it said in a statement.

"The company currently expects the comparable store sales trend in the negative high single-digits to continue throughout the month of August."
