Response from Robinhood:
On May 26, 2020 Ritter Pharmaceuticals (RTTR) performed a 1 for 25reverse split and changed its ticker symbol to QLGN (Qualigen). This means shareholders will now hold 1 share of QLGN for every 25 shares of RTTR previously held. Fractional shares will be paid as cash in lieu. Additionally, shareholders will receive a contingent value right (CVR),which pays additional cash if the company hits certain milestones.
