minimum bid price requirement regulatory

"regarding non-compliance with the minimum bid price requirement of $1 per share"

A minimum bid price requirement is a rule that a stock must trade above a set price for a specified period to stay listed on an exchange. It matters to investors because falling below that threshold can trigger warnings or removal from the exchange, which can cut liquidity, reduce visibility, and often lead to sharper declines in share value—think of it like a venue’s minimum dress code that, if not met, can bar a performer from the stage.

reverse stock split financial

"options to restore compliance, including, if necessary, a reverse stock split"

A reverse stock split reduces a company's number of outstanding shares while raising the price per share proportionally, so the total value of each investor's holding is unchanged; a 1-for-10 split turns 100 shares worth $1 each into 10 shares worth $10 each. Companies often do this to regain compliance with an exchange's minimum price rule or to attract investors who avoid very low-priced stocks.
