This change of CUSIP/stock symbol is no smooth process. From what I could understand, an application was filed some time ago but then more forms were requested by FINRA. As with all other government agencies, this is par for the course. Everything was completed by Bayport in a timely manner and has been in the hands of the agency for a while now.
It won't be long before these changes go into effect -- perhaps one or two more business days, from what I am hearing. I don't know how soon the first PR will be released, but it will not be more than a few days thereafter. This thing is ready to explode. Hold on tight to your EXTO shares. They will be worth a lot more by the end of next week. IMO
