I just noticed something on TDAmeritrade regarding

I just noticed something on TDAmeritrade regarding the name. When I went to check the price something looked off. So I rememerbed I took a screenshot of the price to send to someone few days agao and it had the letters PN next to the name. Today the letters PN are gone, I asked a friend of mine and he is not sure but he THINKS PN means pink sheet. If they removed it, that could mean its uplisting. Just thought I should share. Anymore with more knowledge please feel free to chime in. Thank you.
