Sure if Advent were an NWBO subsidiary then NWBO stock might have been very well at $5. Unfortunately, Advent is a Toucan/LP subsidiary paid by NWBO shareholders and thus we, NWBO shareholders, gain nothing in market value from Advent being a wonderful "cell-run-based immunotherapy factory". I bet Advent is worth more than NWBO's current market cap. Yes Linda really stole money out of the pockets from NWBO shareholders.
So the HTA inspection noted that Advent only had 2 minor infractions in importing frozen tumor samples. And that no other HTA activities were performed.
How hard is it to import frozen material?
Now, if they said anything about manufacturing with it, then you would have a modest point. But everything other than just import is noted as not being actively performed.
