It looks as if Exxon Mobil has it all. It's not only No. 1 on this year's Fortune 500 list, it has also topped our list of most profitable companies. With a total profit of $41 billion for 2011, Exxon surpassed all of its Big Oil competitors, including BP, Chevron, ConocoPhillips, and Shell.
The company repurchased 278 million shares of its common stock at a gross of $22.1 billion. It also struck a deal with oil giant Rosneft to explore for oil in Russian-controlled portions of the Arctic Ocean and Black Sea.
