I have not even received the "computershare paperwork" that you are referring to. But I am US based, so not sure if that applies. If they haven't yet issued the shares, will NVGN stock drop accordingly, when they do?
Wait for the good news soon to be announced from the company.
Something big is happening " corporate action " may be buyout from big pharma/financing deal.
until then you cannot do anything with the paperwork which you received recently from computershare.
