Delisting of securities means removal of securities of a listed company from a stock exchange. After delisting, the securities of that company would no longer be traded on that stock exchange. Delisting can be of two types- Voluntary Delisting and Compulsory Delisting. In voluntary delisting, a company voluntarily decides to delist its securities from a stock exchange whereas in compulsory delisting, the securities of a company are removed from a stock exchange as a penal measure for not complying with various regulatory requirements. The promoters of these delisted companies will be required to purchase the shares from the public shareholders.
