The historical case of Enron and Arthur Andersen is instructive. No one from Andersen went to jail but it had to be argued up to the Supreme Court for their charges to be dismissed. The company was disbanded but the conviction against it was overturned afterwards. This is certainly some evidence for "killing the company" not being the right move.

Several Enron execs did go to jail: Kenneth Lay the chairman would have gone for 10+ years but died before sentencing, Jeff Skilling did 12 years, Causey did 5 years, Fastow did 5 years.

In the current environment of DOJ corruption I don't think this sort of thing would happen... unless the executives were conveniently non-supporters of the current President.
