Inherently, the proposed deal Cubist has came forward with would say yes, $15.50 is a price THEY are willing to pay (BEFORE THE NDA). <-- That to me screams overwhelming confidence.
One could infer from this that TSRX is ACTUALLY WORTH MORE than $15.50 per share, since Cubist is already willing to pay $13.50 + a $2.00 CVR which at the end of the day = $15.50 per share or $818 Million for the entire deal.
So theoretically, if investors agree that TSRX is already worth $15.50 a share (WHICH CUBIST AND I THINK IT IS), it could easily see a PPS in that range VERY SOON.
Huge close here today guys! I smell $15's cooking ;)
