Costco's quarterly comp sales miss estimates

Oct 5(Reuters) - Warehouse club retailer Costco Wholesale Corp reported lower-than-expected quarterly comp sales on Thursday, as fewer customers visited its outlets.

Sales at established stores open at least a year rose 5.7 percent in the fourth quarter, excluding the impact of changes in gasoline prices and foreign exchange, the company said.

Analysts on average were expecting same-store sales to rise 5.10 percent, according to research firm Consensus Metrix.

Net income attributable to Costco rose to $919 million, or $2.08 per share, in the 17-week quarter ended Sept. 3, from $779 million, or $1.77 per share, a year earlier.
