Delisting occurs when a security is removed from a stock exchange, either voluntarily or involuntarily. It happens for various reasons: some companies do it as they cease all operations, others opt for it as the result of bankruptcy. Among other reasons there are merging with another company, failing to meet listing requirements, or the transition to private ownership.
A stock's fate depends on the way the company delisted. If it delisted voluntarily, its shareholders typically receive cash as a buyout or corresponding shares in the acquiring company. However, when a company is forced to delist, shareholders have to either find a buyer on the exchange, or keep holding shares of an unlisted company.
