NEW YORK (AP) — Wal-Mart Stores Inc. once again leads Fortune's list of the 500 biggest U.S. companies by revenue, as the world's largest retailer succeeded in posting strong growth despite a challenging economy for its shoppers.
The Bentonville, Ark., company's revenue grew nearly 6 percent in 2012 to $469.2 billion.
Exxon Mobil Corp. dropped to the second spot, with revenue of $449.9 billion, but was still the most profitable. Energy companies continued to dominate the top of the list, with rival oil and gas producer Chevron Corp. holding steady at No. 3 and refiners Valero Energy Corp. and Phillips 66, spun off from ConocoPhillips last year, joining the top 10.
Fortune Magazine released its annual ranking on Monday.
Moving up two spots to No. 5 is Warren Buffett's Berkshire Hathaway Inc., which owns everything from insurers to railroads to newspaper publishers and is in the process of acquiring Heinz Co. Manufacturing stalwarts General Motors Co., Ford Motor Co. and General Electric Co. slipped in the survey but all remained in the top 10.
