If companies on the Pink Market are not in compliance with the new regulations in time, they risk losing their public market. While the SEC set September 28 as the compliance date, OTC Markets Group has given these Pink Market securities until June 30 to review the new guidelines and provide the necessary information to ensure they meet the new standards in time.

For investors, that September deadline is when you will see the non-compliant securities drop out of the Pink Market.
