Expropriate the company, at least 51%, take control and let public officials (knowing the US way, it will be some army general) set up checks and controls where necessary, then sell the shares (maybe keep an 'oversight' part, like 10% to keep a state official on the board).
Current stock owners will loose half their value (which is a good enough punishment for this lack of oversight), the state will have access to privileged company information which will allow the prosecution of human responsibles, top executives will be sacked (and their comp reduced by half since their comp is in stocks) and maybe the company will start on good base again.
