Wal-Mart reported its U.S. same-store-sales, excluding gasoline, grew 1.7% amid a 1.9% increase at its namesake chain and 0.1% rise at Sam’s Club.

Vice Chairman Eduardo Castro-Wright said the company, which last month projected growth at the higher end of the quarter’s predicted 1% to 3% advance, said Thursday the holidays were more challenging than expected for retailers because of the economy and "severe winter weather" in some parts of the country."
