Put youself in MT's shoes and really try to be objective:
You have built a strong healthcare company with a global network and great cash flow ability. Your share price has stampeded from $7 to $117 in less than two years. Things couldnt look better until the failure of a company in your sector, a negative market sentiment, and a vicous short selling attack drive your share price all the way down to an unbelievable $25. You can't do much to refute the short selling tactics except run your company to the best of your ability. You do just that and deliver two strong quarters only to see your stock price make small recoveries before being driven down to $30 over and over again. In the midst of your stock price struggles, you are approached by firms looking to buyout your company and end your stock price struggles once and for all. As you watch your stock price continue to bounce around near all time lows, you come closer and closer to a deal that will be benefital to both parties. Your stock price has made a slight recovery by now as your most recent earnings and the prospect of a buyout have finally created a positve atmosphere for you stock. However a day of ridiculous rumours and possibly very illegal activity, crumbles your stock a ridiculous 25%. You know that short interest in your stock is as high as ever and you are getting closer to a buyout deal every day.
Now what would you do? Would you rush to make a press release refuting the short attack and the false rumours in hopes of stoppin the further detierioration of your share price, while giving the shorts a reason to cover? Or are you content watching your share price slip day after day knowing the the shorts are getting greedier and greedier, while you are extremelly close to striking a deal that will fry all those who ruined your beautiful company and reward all those who have loyally stuck with your company?
Seems like a pretty easy decision to me.
