Personally I'd say you are making up news. The new presentation's only change is to say they are going to start a comparison of competitors which will take a minimum of a year. No mention of their FDA process or an update. This wild fabrication of a bombshell buyout coming at $2 to $4 imho is absurd. $4 puts their valuation at $700M. Got to be kidding. There is no mention in any PR about negotiations going on.
They will run out of cash before the competitor comparison is complete and need to do another huge PP.
