Haven't thought that far ahead yet.
Before I do, I first want to see the POR. If DESTQ shares are NOT being cancelled, then the POR should give some information on what will happen with the old DESTQ shares.
At a minimum, DESTQ shares would need to be exchanged for shares with a new ticker symbol. A name change would probably be in order as well. I believe FINRA would be the one involved with those changes.
As the transition from DESTQ shares to a new ticker progresses, there would be a period of time (usually a few weeks) when the new shares would be difficult to trade. Once the new shares get officially listed on OTC Markets, they would have to become "current" by OTC Market rules.
Unfortunately, I don't know how long this process might take in the current market environment. Of course, if the new company wanted to list directly on NASDAQ or NYSE, that might actually be the easier thing for them to do.
All is just my own opinions.
