I have asked a question What shares are actually being sold in “ATM” format release? - From the answer, I understand that a company could be able to sell new shares to gain more money for its operation.
But when will the public be notified?
Let's still take the $HMNY company for instance. It's been jumping lower for days. Does that mean the company has already (secretly) selling new shares ATM? Is that legal? How does the ATM offering actually work?
