It's possible that more shares have been converted since 8/15. However, it could also be largely explained by naked shorting, day trading and MM's doing their normal naked shorting to cover day traders and their own butts.
This company was essentially reborn on November 13, 2018 when Satel Group merged with Simulatus Corp. Satel paid off the Simulatus shareholders and took over management of the company and their financials became the historic financials for SIML...
...At the time of the reverse merger, the company inherited roughly $800,000 in convertible debt. with various due dates. The last 10-Q (as of 6/30/19) shows $1,046,862 in convertible debt (minus discounts of $661,711) with a demand outstanding for conversion of a $150,875 loan. The company has been pretty transparent about their debt and has been diligent in issuing formal SEC disclosures as required. If a lender demands conversion of a note after the due date, management has to comply. There is no choice for the CEO other than to try to negotiate with the lender but the lender holds all the cards. We have seen, however that the company has paid off several of these convertible loans and is committed to paying off more before they convert.
Consequently, while I'm not yet prepared to recommend a buy, I think much of the criticism on this board is hysterical and unfounded.
