You are very wrong the same rules apply. The OTCQB is not a national exchange as defined by the SEC act. They are an OTC exchange that has some disclosure rules they apply. But far less than the NASDAQ and NYSE which must abide by rules of national exchanges.
For example, failing to hold the ASM in the same fiscal year would be a violation of NASDAQ rules. So would have been the failure for the same several years ago. And the failure to be on time with financials a few years ago. And the failure to vote on the "top up" options.
There is a reason why NWBO fled the NASDAQ before they were booted for corporate governance failures.
Where's the annual meeting? Where are the updated news releases? Where is Alt DC on their website? They only provide the absolute minimum, ... 4 Qs and One K ... And if you bother reading the Qs, which most dummies don't..... you will see what's going on here... Stock printing factory! And there are still 500 million more shares that have been secretly authorized ( hint; more dilution coming) last year in addition to the almost 1.2 Billion shares ... already issued!
