9. Sunoco
Fortune 500 rank: 78
2009 revenue: $29.6 billion
2009 total shareholder return: -37.3%
Along with the rest of the refining industry, Sunoco suffered from waning demand for gasoline. The company attempted to cut costs in October by shutting down a refinery and chopping its dividend.
Sunoco's non-refining businesses, like its coke and logistics operations, did relatively better -- but they weren't strong enough to prevent it from reporting an annual loss of $329 million.
