As far as I can tell they meet all of the requirements for Pink Current.
I agree.
However it seems to me that OTCMarkets may be in a transition period between Pink Current and OTCID designations. So perhaps they are not upgrading VMST to Pink Current until they file the "annual Management Certification or 12g3-2(b) Certification", even though this is NOT currently required for Pink Current, only for OTCID. Seems a bit arbitrary to me, but that is all I can come up with to answer your original question.
