Lowe's quarterly profit more than doubles

Nov 21 (Reuters) - Lowe's Cos Inc said on Tuesday its third-quarter profit more than doubled, helped by lower costs as well as higher demand for emergency supplies and rebuilding material due to hurricanes battering several regions in the United States.

Sales at stores open at least a year increased 5.7 percent, above the average analyst estimate of 4.6 percent growth, according to Thomson Reuters I/B/E/S.

Net income rose to $872 million, or $1.05 per share, in the third quarter ended Nov. 3, from $379 million, or 43 cents per share, a year earlier.
