Section 12(j) of the Exchange Act, grants the SEC the authority to revoke a company’s Exchange Act registration when it has a history of delinquent filings. Often, an SEC proceeding to revoke registration pursuant to Section 12(j) will be preceded by a 10 day suspension in trading. Brokers cannot resume quotations until they determine that the issuer has satisfied the information requirements of Rule 15c2-11, which will not likely occur because the issuer failure to file its periodic reports caused the revocation or suspension. https://www.securitieslawyer101.com/2014/section-12-termination-registration-trading-suspensions/
