Reverse Book Building For Delisting

1. Meaning of Reverse Book Building (RBB)

Reverse Book Building is a price discovery mechanism used in voluntary delisting of equity shares, where:

Public shareholders quote the price at which they are willing to sell their shares, and

The promoter decides whether to accept the discovered price that enables attainment of the delisting threshold.

It is called “reverse” because price is discovered from sellers (shareholders), not buyers.

2. Statutory Framework

Reverse Book Building is governed by:

SEBI (Delisting of Equity Shares) Regulations, 2021

SEBI Act, 1992

Relevant SEBI circulars and stock exchange procedures

Earlier governed under the 2009 Delisting Regulations, now consolidated and streamlined.

3. When Reverse Book Building Is Mandatory

RBB is compulsory in cases of:

Voluntary delisting by promoters

Delisting pursuant to acquisition or restructuring

Delisting of companies other than small companies

📌 RBB is not applicable to:

Compulsory delisting

Delisting of certain small companies (fixed-price route permitted)

4. Key Elements of Reverse Book Building

(A) Floor Price

Determined as per Regulation 20 of Delisting Regulations

Based on pricing principles under SEBI (SAST) Regulations

Acts as minimum protection for public shareholders

(B) Bidding Process

Conducted through stock exchange platform

Shareholders can:

Bid at floor price, or

Quote a higher price

Bids below floor price are invalid

(C) Discovered Price

The highest price at which promoter shareholding reaches:

90% of total issued share capital

This price is known as the discovered exit price.

(D) Promoter’s Option

Promoter may:

Accept the discovered price → delisting succeeds

Reject the discovered price → delisting fails

📌 Promoter cannot force shareholders to accept a lower price.

5. Threshold Requirement (90%)

Promoter + PAC must reach 90% shareholding

If threshold is not achieved → RBB fails

Ensures substantial shareholder consent

6. Post-Delisting Exit Window

Remaining shareholders get 1-year exit opportunity

At the same discovered price

Prevents unfair exclusion of residual shareholders

7. Objectives of Reverse Book Building

Market-driven price discovery

Minority shareholder protection

Transparency and fairness
