I have already called you out on this. Yes, shareholders MUST be notified before a reverse split. What you are peddling is FALSE.
Here it is again, maybe this time you will read and try to understand it.
SEC Rule 10b-17 is the main regulation dealing with stock splits. Rule 10b-17 is an anti-fraud regulation of federal securities law. The regulation requires that issuers of publicly traded securities provide timely notice of certain corporate actions, including stock splits, reverse stock splits and the issuance of dividends. The notice must be provided at least 10 days before the record date for the corporate action.
