Exxon Back At No. 1 On 'Fortune 500' List; Wal-Mart Knocked To No. 2

After two years in second place, Exxon Mobil is back on top of the Fortune 500.

With 2011 revenues of $452.9 billion, the oil and energy giant edged out Wal-Mart Stores, which brought in $447 billion, Fortune magazine just reported.

Wal-Mart took the top spot from Exxon Mobil two years ago and held on to it again last year. Soaring oil prices are a major factor in Exxon's move back to No. 1.

Exxon far outpaced Wal-Mart when it comes to profits: Earning $41.1 billion to Wal-Mart's $15.7 billion.
