Exxon Mobil Corp. unseated Wal-Mart Stores Inc. in the 2009 Fortune 500 list, shrugging off the oil price bubble and weathering what the magazine called the worst year ever for the country’s largest publicly traded companies.

Fortune’s closely watched list, released Sunday, ranked companies by their revenue in 2008. Irving, Texas-based Exxon took in $442.85 billion in revenue last year, up almost 19 percent from 2007. The company also raked in the biggest annual profit, earning $45.2 billion.

Exxon Mobile was not alone at the top:

Energy companies continued to dominate many of the top positions, as last summer’s skyrocketing oil and gas prices more than compensated for their plunge later that fall. Chevron Corp. held on to third place with $263.16 billion in revenue, up 25 percent. ConocoPhillips climbed one place to fourth, with $230.76 billion in revenue.

Perhaps it is time for the administration to consider a windfall profits tax again?
