They did the same when they announced the holds if I recall correctly, it was a press release followed by a pre market CC, to clarify the situation and reduce the severity of the impact. I started to conclude that the HIV BLA is going nowhere few years ago, especially when Mahboub rahman left, an expert that came, saw nothing pleasing, and bounced, and it has been an obscure situation since, swept under the rug until now.
I don’t think this will cause a major blow to the SP and honestly who cares, most longs are in the full gamble mode at the moment, take it all or lose it all. There is no difference between 40 cents or lower if you are not selling. Good luck!
