Since WYE shareholders are getting a set amount of cash and a percentage of a PFE share, it would seem to me that the deal will simply get worse and worse for them as each day progresses! I know that I must be missing something...
You seem to be assuming that PFE’s stock will continue to fall between now and the deal closing. On what basis do you make such assumption?
As I’m typing, PFE is trading at 16.00 and WYE at 44.40, which is a wide 9% discount to the $48.76 deal value implied by PFE’s current price. Inasmuch as the risk of the deal not closing is small (IMO), WYE is a better buy than PFE at the current prices.
