Staples' weak sales report comes after smaller rivals Office Depot Inc
Third-quarter sales outside the United States fell 1.9 percent to $1.3 billion, mostly due to a 12 percent decrease in comparable-store sales in Europe and lower sales in Australia.
European shoppers are struggling with a mix of inflation and high unemployment rates, against the backdrop of the euro zone's debt crisis.
In the third quarter ended on October 29, net income rose to $326.3 million, or 47 cents a share, matching the average estimate as compiled by Thomson Reuters I/B/E/S. A year earlier it earned $288.7 million, or 40 cents a share.
Sales rose slightly to $6.57 billion, compared with the average estimate of $6.72 billion.
Staples expects to earn a net profit of $1.38 to $1.42 a share for the full year, down from its previous outlook of $1.42 to $1.48.
