Let's see here:
Saunders packages up the Actavis generic division with a nice, big red bow and sells it to Teva. Teva nearly goes bankrupt and the dog of a division drags down AGN stock for over a year.
Bill-of-goods.
Next, Saunders packages up FRX, ACT, and AGN into one messy conglomerate, puts some polish and fresh smiles out front and dangles "inversion deal" to PFE for around $350 / share.
PFE stockholders should get on their knees and thank that jackass Jack Lew in the Treasury Department for squandering the deal. If you look at the resulting mess that this frankenstein-mashup of three formerly quality companies have transmogrified into -- and look at the current performance, stock price, portfolio, and talent level?
Bill-of-goods.
Esmya is going to be a very limited-use product (if it makes it to market.) Rapastinel will be just another antidepressant, except administered with a needle (which Psychiatrists hate.) It will have no "immediate effect." That's the realm of Roche with their nasally-administered esketamine.
Slick Saunders has reached the end of his dog and pony show. If he manages to unload this dumpster fire onto PFE even at the current stock price he'll be doing all existing stockholders of AGN his final good deed.
