Home Depot Inc
The news came on Monday, a day after Lowe's reported weaker-than-expected quarterly sales and cut its fiscal-year outlook for the second time in three months.
Home Depot still expects fiscal-year sales to be up about 2.5 percent. It forecast earnings of $2.34 a share excluding future stock repurchases, up from a prior forecast of $2.24.
In the second quarter, Home Depot's same-store sales, or sales at stores open at least a year, rose 4.3 percent globally, including a 3.5 percent rise in U.S. same-store sales, making it the ninth consecutive quarter that it has outshone its smaller rival.
Lowe's same-store sales fell 0.3 percent in the quarter.
Home Depot also beat estimates on quarterly profit as demand picked up for seasonal goods after a soft start to the spring selling season. Storm-related repairs also helped the retailer's sales.
Its second-quarter net income rose to $1.36 billion, or 86 cents a share, from $1.19 billion, or 72 cents a share, a year earlier.
Analysts on average were expecting 83 cents a share, according to Thomson Reuters I/B/E/S.
Sales rose 4.2 percent to $20.23 billion, beating analysts' average estimate of $19.96 billion.
