I am trying to understand the logic of completing a placement before the FDA announcement. Surely, an opportunity to guage the demand relating to the shares following the announcement would have been prudent, which would then provide a true reflection of the value of the shares and a price for the shares via the placement would show a reasonable discount for the shares and maximise the amount received per share which would:

minimise dilution
Prevent, those instos and sophisticated shareholders from selling shares ( already owned) into this announcement rally knowing that they are already significantly in the money with the shares they will receive.
