Wal-Mart, the world’s largest retailer, has seen sales fall in its home market and said that conditions in the US remain “challenging”.
Group same-store sales in the US fell 1.6% in the three months to January.
Overall sales, including its overseas businesses, rose 4.6% to $112.8bn (£72.4bn). Net profit rose 22% to $4.63bn from $3.8bn a year ago.
UK supermarket Asda, which is owned by Wal-Mart, reported a 4.6% rise in sales in the quarter.
Asda chief executive Andy Bond said the group had beaten its sales and profit targets for the three months and the full year.
