Seems like the stock is cheap on Europe alone. Brean analyst has a $400MM estimate peak sales. Only trading at roughly 1x peak sales. US market not factored.
Brean also did a DCF at 10% and came up with a NPV of $950M or over $60 ps, thus the PT of $60. Brean says their assumptions are "conservative" (low).
Since I posted last, Wedbush raised their EPS estimates which I roughly convert (Euro- $) as $0.60, $1.80 and $4.00 for 2013-2015. PT 35 (which they will have to raise - probably sooner than later).
