Reverse Book Building

Reverse book building is the price-discovery process used in a voluntary delisting, where public shareholders bid the price at which they will tender shares.

In a delisting, instead of investors bidding to buy, public shareholders submit the prices at which they are willing to sell their shares back to the promoter. The discovered price is the one at which the acquirer reaches the required acceptance threshold, and the promoter can accept or reject it.

SEBI's Delisting Regulations govern the mechanism, including a floor price and minimum acceptance conditions, to balance fair value for minorities with feasibility for the acquirer. It is the mirror image of the book building used in an IPO.
