You are 100% spot on. Except for the use of the word "uplisted". AABB trades OTC and, unlike legitimate Nasdaq and NYSE companies, is not a 'listed" security that trades on an exchange. More importantly, it is a dark, non-filer, as you stated.
The US is the only country with major stock trading that allows a company to trade without the benefit (a huge one for potential shareholders) of being required to file audited financials, quarterly and yearly.
