When I read your post below when you posted it, I for one thought it was a possibility, but I did not mark a "like" at the time because I did not want to promote any negative theory, even though I thought you might be right. However, frankly, I am more inclined both at the time you posted this and now to believe it might be a firing (or a resignation in lieu of firing-hey, we are about to fire you, you want to resign instead so you can tell your next employer that you quit?). However, after thinking about it, and concluding that you might be right that Dr. Rahman was leaving, I considered the fact that Dr. Rahman appeared to have not moved the needle on the HIV BLA refiling one bit, and said to myself, so be it, and held my entire position. Unlike another good poster on this board who regrets not selling today, I did not even consider it. We are probably on a path to a faster refiling now that he has left under whatever unknown circumstances it was.
