I really think the headline will be very simple, something like..."Takeda completes Omontys' safety investigation, no fault found with Omontys. FDA concurs with findings. Omontys to be available in X days for distribution to dialysis facilities. Please contact _____ for more information at 555-555-6789."
Short, sweet, no finger pointing (all of that will be behind the scenes worked out with Fresenius ahead of time).
If this was a likely scenario do you really think the stock would be trading $1? There are a lot of smart people out there that would bid up the shares if that were the case. Hedge funds with billions of capital would sure get involved, no?
