While the Corp will end up administratively dissolved, I don’t think anything else will happen other than brokers, at some point, removing the “BioAmber shares” from their customer’s accounts or requiring a fee to maintain them...but that could be a year or two before that even starts happening.
The Delaware action (likely for lack of tax/annual filing) itself shouldn’t trigger a FINRA action...as it is no longer publicly traded.
I think FINRA did all they intend to do.
Which is cruel in a way as people can see the “stock” they just will never ever be able to sell it.
