Customers at the nation’s largest home improvement retailer appeared to shrug off any concerns about a data breach as Home Depot’s sales increased 5.4% to $20.5 billion. Comparable store sales increased 5.2%, but grew 5.8% at U.S. stores. The increased productivity at existing stores drove profit growth, with earnings increasing to $1.5 billion, or $1.15 per share, compared to $1.4 billion, or $95 cents a share, the prior year.
