The SEC filing dated October 1 includes the following statement:
"The transaction remains subject to customary closing conditions, including regulatory approvals. The transaction is expected to close during the fourth quarter of 2020."
Since it is clearly not a done deal yet, the common stock will continue to trade (for now). With more than $1 billion in annual revenue, and the stock having hit .01 today, I expect there is still some opportunity for profit here before the story ends.
As always, simply my opinion.
