The only reason they haven't gone bankrupt yet is because of how they handled it. They knew from the beginning that it wasn't getting capped and it was going to be the worst incident in recent human history ecologically. By downplaying how bad it was, not admitting anything, etc they put speculation in the hands of regular people who are too stupid to realize this is a serious problem.. prolonging the amount of time they had before they lost all value... allowing them to possibly "accidently" fix it by some random means.
