WPI seems to be weaker on the back of a WSJ article that talks about Actavis EU 300m in EBITDA in 2011. So they're paying 14-15 times that at 4.5B euros ? Seems a bit pricey even if you account for the 300M in cost synergies.
… paying ~3x sales to acquire Actavis strikes me as excessive and is symptomatic of empire building. If they can get it for only 2x sales, it’s a different story.
