RTRX proposes to acquire TSPT for $4/sh in cash: http://finance.yahoo.com/news/retrophin-proposes-acquisition-transcept-4-200000456.html The proposed buyout price is a 20% premium to yesterday’s closing price, but only an 11% premium to today’s. Why is RTRX interested in TSPT? Presumably for the cash and NOL’s (see immediately following post).
