According to the WSJ today, AGN's largest holder, Cap Research, has sold their entire interest in AGN, around $2B worth. they have been a holder since 2007. I note also that Paulson now has a $1B interest in AGN. So here we see long term shareholders being replaced by folks that appear to be playing the deal.
Regardless of the merits of AGN's plans for the company, it's fate increasingly is in the hands of deal arbs. Not good news for AGN supporters.
