FINRA has no control over the amount of stock OTC companies authorize. Raising or lowering the a/s is not considered to be a corporate event that must be reported to, and processed by, FINRA.
FINRA DOES have to process reverse (and forward) splits. Because RETC is a delinquent filer, the regulator could deny the company's corporate action request, if it made one or makes one before catching up with its filings.
