Too many variables to be guessing here, but wouldn't be surprised if they have already bought a good deal of the shares back already. Seems strange that a large holder suddenly starts selling around the same time.
I hope we hear from our BOD today and they can shead some light on what is going on.
If PRIM have found a way around the lock in agreement tell us.
We know they have very experienced board members legally and financially plus know a lot of people in business. Sometimes it's who you know not what you know.
J7st thought they might have done some deal behind the scenes by now as seems too long for there to be no news. But probably over thinking it. That's the trouble when no news the mind runs away.
