Aug 14 (Reuters) - Wal-Mart Stores Inc reported a 2.8 percent rise in quarterly sales, helped by higher sales at its smaller-format stores, but U.S. same-store sales failed to show growth again.
Wal-Mart also cut its forecast for full-year earnings from continuing operations to $4.90-$5.15 per share from $5.10-$5.45, citing higher employee healthcare costs and increased investment in its online business.
Net income attributable to the company rose to $4.09 billion, or $1.26 per share, in the second quarter ended July 31 from $4.07 billion, or $1.24 per share, a year earlier.
U.S. same-store sales were flat in the quarter.
Total revenue rose to $120.13 billion. (Reporting by Sruthi Ramakrishnan in Bangalore; Editing by Kirti Pandey)
