Delisting

Delisting is the permanent removal of a company's shares from stock-exchange trading. It is voluntary when promoters buy out public shareholders to take the company private, and compulsory when the exchange removes the stock as a penalty for non-compliance.

Voluntary delisting is governed by SEBI's Delisting Regulations: promoters must get shareholder approval (with public shareholders' votes counting disproportionately) and then acquire enough shares to cross 90% of the company. Price discovery traditionally happens through reverse book building — public shareholders tender at prices they choose — and SEBI has also enabled a fixed-price route at a premium to a floor price for frequently traded shares. If the 90% threshold isn't reached, the delisting fails and the stock continues trading.

Compulsory delisting is different and worse: the exchange forces it for persistent non-compliance, promoters can be barred from the market, and an independent valuer sets an exit price that minorities can accept for a limited window. Liquidity effectively dies, which is why compliance-related alerts on small caps deserve attention before it gets that far.

For investors in a voluntary delisting, the decision is whether to tender at the discovered/offered price or hold unlisted shares (with an exit window at the same price for a year after delisting). Holding unlisted paper of a promoter-controlled company is rarely attractive, so the offered exit usually is the decision.

How stocks tend to react

Voluntary delisting announcements often move the stock sharply toward (and sometimes above) the expected exit price, as the market handicaps both the final discovered price and the odds of success — failed delistings tend to give back much of that move. News that raises compulsory-delisting risk is almost always taken badly.

MarketPing measures this instead of guessing: every analysed announcement carries the stock's actual price reaction across 14 horizons, and the Reaction Lab aggregates how each category of announcement has historically moved stocks.
