He makes for very poor CEO material. A real CEO knows how to take advantage of the info:
Immediately: Promote Dilbert, and thank Dilbert for the information. Feign genuine concern, and reward Dilbert with an executive promotion. Same day send Dilbert, as a new and trusted executive on the corporate jet to meet with the customers with a directive to advise that the sales can't be completed.
While Dilbert is in the air, sell off all vested preferred stock with a buy-back option.
When Dilbert lands, CEO contacts CIA, advise them that one of his executives (Dilbert) has gone rogue, and is planning to sell drones to terrorists. Deny any previous knowledge or involvement. Press release the info with an apology.. stock value plummets.
Likely the terrorists will kill dilbert when he refuses to sell, and if not, Dilbert takes the fall anyway. CEO makes a killing from selling the stock, then can buy it all back after it's devalued from the hit at great savings, applies to the government for a "too big to fail" stimulus package, which reinforces the stock.
