it might not even happen that way...right now I am confident(but have no actual knowledge) that XXII management has done preliminary inquiries into requirements for all exchanges and have zeroed in on one.
Next, they would submit docs to determine if the docs are in order as required for exchange...
last step...the trigger...whatever it is...usually price/length of time...when that is reached...bingo...and days for approval...
IMHO...probably will have simultaneous announcement/approval, or at least announcement of submission(knowing it is going to qualify and is days away)...they have already told investors of their intentions to uplist...
"doing" and "done" is always more preferable to "we are almost there"...over and over...
