Get quote: WMT The retail giant reclaims the top spot on the Fortune 500, making it the largest company in the United States for the fifth time in six years. The company suffered a series of public relations gaffes last year, but has launched a crusade to spruce up its image. It now employs 1.9 million people worldwide and revenues are up 11% over last year, but profits grew less than 1%, amid a slowdown in same-store sales.
