Delisting is when a company's shares are permanently removed from a stock exchange, so they can no longer be bought or sold there. It can happen because the company chooses it, or because the exchange forces it.
What delisting is
A listed company's shares trade freely on exchanges. After delisting, that public trading stops. The company itself may continue to operate normally, but its shares become much harder to sell, because there is no exchange where buyers and sellers meet.
Types of delisting in India
Voluntary delisting: the promoters or acquirers decide to take the company private by buying out public shareholders. SEBI's delisting regulations set the process, which includes shareholder approval and a price discovery mechanism. Traditionally this used reverse book building, where public shareholders tender shares at prices they choose, and the delisting succeeds only if enough shares are tendered. SEBI has also introduced alternatives such as fixed-price offers in certain cases.
Compulsory delisting: the exchange removes a company for serious, prolonged violations, for example failing to comply with listing rules for a long time or remaining suspended. In such cases, promoters may be required to buy out public shareholders at a fair value determined by an independent valuer, though in practice recovery can be difficult.
Delisting after a merger: when a company merges into another, its shares are cancelled and delisted, and shareholders receive shares of the surviving company.
A simple example
A multinational parent owns 80% of its Indian subsidiary and wants to delist it. It seeks shareholder approval, and public shareholders tender their shares through the delisting process. If enough shares are tendered at an acceptable price, the parent buys them, the shares are delisted, and remaining shareholders typically get a window to sell at the same price for some time afterwards.
Why it matters for investors
Delisting can be an opportunity (voluntary delistings sometimes happen at a premium) or a serious risk (compulsory delisting can leave shareholders holding shares that are very hard to sell). Watching for warning signs, such as repeated non-compliance, suspension of trading or long delays in results, helps you avoid being trapped.
Warning signs
Companies heading towards compulsory delisting often show patterns: persistent delays in filing results, regulatory penalties, auditor resignations, trading suspensions and very low trading activity. Any of these deserves a closer look.
Suspension versus delisting
A suspension temporarily stops trading in a share, often because the company has not complied with rules, such as failing to file results. If the company fixes the problem, trading can resume. Delisting is permanent removal. A long suspension can be a step towards compulsory delisting, so investors should treat it as a serious warning.
Common misconceptions
"Delisting means the company has shut down." Many delisted companies keep operating.
"My shares become worthless." You still own them, but selling becomes difficult.
"Delisting always pays a premium." Voluntary delistings may; compulsory ones often hurt shareholders.

Summary
Delisting removes a company's shares from a stock exchange. In India, it can be voluntary (promoters buy out public shareholders through a SEBI-regulated process), compulsory (for serious violations) or follow a merger. Voluntary delisting can offer an exit at a fair price; compulsory delisting can trap shareholders. Watch for warning signs such as suspensions and delayed filings.
