Looks like they are trying to get listed on NASDAQ, IMO
The Letter "C"
Similar to the letter "E," a ticker symbol with a "C" in the fifth position stands for Issuer Qualification Exception, which indicates a potential problem: The issuing company does not meet all Nasdaq stock exchange listing requirements. However, the stock can remain listed on the exchange and will be exempt from listing requirements for a short period. Ticker symbols with the letter "C" also require more investigation to determine reasons for the failure of meeting Nasdaq listing requirements.
