With a 15-12G filed the company does not have to file an audited 10k annual report. That is only for SEC fully reporting companies an option $GLUC has decided to get away from. I assume it's because of financial constraints. Accounting costs on a startup can become an overwhelmingly costly burden.
My guess is the company likely de-registered so they could save money and post Annual and quarterly reports unaudited.
It makes sense for a growth company to reserve capital. They don't need audited financials. The CEO would never file a false or incomplete report anyway.
