Fortune 500 rank: 176
2012 loss ($ millions): -4,242

The Virginia-based IT services provider suffered a huge $4.2 billion loss last year after having to record several write-offs on underperforming projects, the biggest of which was its disastrous contract with the U.K.'s National Health Service (which cost it $1.5 billion). Mike Lawrie, who took over as CEO in 2012 was charged with turning around the company and he responded by selling off multiple businesses and reducing management layers. The company is slowly recovering; it posted a healthy profit of $513 million in this year's first quarter, up from a loss of nearly $1.4 billion in the same period last year.
