1. Introduction to Bookbuilding Process

Bookbuilding is a mechanism used by companies to determine the price of shares in an Initial Public Offering (IPO) or Follow-on Public Offering (FPO) based on investor demand rather than a fixed price.

It is widely used in India and global capital markets to achieve market-driven pricing and improve transparency.

Key Features:

Price is determined based on bids submitted by institutional and retail investors.

The issuer and underwriters set a price band for bidding.

Successful bidders receive allocation based on demand and regulatory guidelines.

2. Legal and Regulatory Framework in India

SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018 (ICDR)

Governs pricing, allocation, and disclosure requirements for bookbuilt issues.

Requires minimum 75% of the issue to be allocated through book building (for public companies).

SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015

Disclosure of pricing methodology and allocation process in the offer document.

Companies Act, 2013

Sections 23, 42, 62 – regulates issuance of shares to the public.
