I found at the Oklahoma Secretary of State website

I found at the Oklahoma Secretary of State website that the company had a new entry Nov ^th , last wednesday . They filed a new certificate of designation . The info is publically available so i ordered it. CRTG got 150,000 Series D preferred shares authorized .I didnt see how many shares each 1 converts into as far as common stock goes . They already have a lot of series C shares approved recently ...I know CRTG is already public but they might be used for an acqusition . CRTGs CEO is the CEO of ZaiCell Inc in Virginia and they are building a 50 giga watt battery manufacturing plant . They are private so im speculating they may want to go public through CRTG ??
