UPDATE 1-Costco April same-store sales narrowly miss Street view

May 6 (Reuters) - Costco Wholesale Corp (COST.O) on Thursday reported a 11 percent rise in April sales at stores open at least a year, but the results narrowly missed Wall Street expectations.

Same-store sales at U.S. locations increased 6 percent, while international sales rose 29 percent.

Excluding the impact of gasoline price increase and strong foreign currencies, comparable sales for April rose 4 percent.

Issaquah, Washington-based Costco said net sales for the four weeks ended May 2 rose 13 percent to $5.83 billion.

Shares of the company closed at $60.36 Wednesday on Nasdaq. (Reporting by Anuradha Ramanathan in Bangalore; Editing by Vinu Pilakkott)
