when a company fails to comply with listing requirements it will receive adequate warning delisting doesn t happen overnight notifications are made and time is granted to the subject to get its affairs in order if the noncompliance continues after these warnings are made the company will then be removed from the exchange 
voluntary delisting works differently if a company decides it no longer wants to operate in the public eye it must consult with its stakeholders first a resolution has to be passed in a board meeting and put to shareholders once enough shareholders are on board the company needs to get the green light from the stock exchange that it wishes to delist from and put out a statement outlining its intent an investment bank will be in charge of managing the delisting one of its first jobs is making sure there is enough money to buy back the shares investment banks don t just assist companies to list their shares they are also recruited to help with the delisting process in order to delist the company essentially needs to buy back a certain percentage of shares from the total outstanding this threshold is decided by the exchange to buy these shares a bidding process occurs a fair price is negotiated and announced to the public and the company pays up within a specified deadline to see its delisting through to convince investors the company will usually have to pay them a premium to the current share price
