Good question. Looks like it has to go through both otcm and Finra. It’s not clear on what the exact steps are from what I’ve found. Although I do know the process starts and ends with Finra, since they do receive initial inquiries to change name/symbol and at the end post them. What happens in between that I have no idea. Some one has to approve it. Otcm requires companies to keep up on disclosures to not get delisted and go to expert. I would imagine they are part of the process somehow. Otc markets is technically not an exchange, but who else would approve these actions if Finra says on their website that they don’t.
