The SEC does not warn them of the impending suspension but they do ask questions, take testimony, issue subpoenas and wells notices... I am currently watching another stock charged with Securities Fraud and then suspended for delinquent filings, that Company knew for over a year of thier SEC investigation as investigative testimony was recorded a year before the charges and suspension. Of course the "company" never said a word to investors and actually had the audacity to continue on with the scam.
