What they stated was they could not identify all the ownership.
Well, that is virtually always true.
They know the shares that are registered at Compushare (their agent). Owner of record is for the most part DTC, some other similar outfits in other countries and major institutions. A few rare individual holders with directly registered shares.
But for that huge chunk in DTC, they might know that E*Trade (for example) has them in their accounts. But they are not legaly entitled to know E*Trade;s customers unless the customers allow it.
So they will never know the beneficial ownership list.
That they used this to convince you of irregularities is just another chapter in their playbook of how to scam retail longs.
