An Initial Public Offering (IPO) provides private company founders with the opportunity to raise long-term capital by selling shares to the public. This method proves cheaper than bank loans, while also allowing early investors to exit fully or partially. Once allotted, these shares trade on exchanges like NSE and BSE in India.
Why Companies Launch IPOs
Companies pursue IPOs for several strategic reasons:
- Raise affordable capital: IPOs provide funds for expansion, R&D, marketing, and new projects without debt burdens.
- Enable exits for founders and early investors: Founders and early backers can sell shares to realize gains.
- Boost visibility and credibility: Listed companies face stricter disclosure rules, enhancing brand trust and regulatory standing.
Key Parties in an IPO Process
Multiple stakeholders participate in every IPO:
- Company: The issuer offering shares to the public.
- Underwriter or Bank: Manages pricing, marketing, and share distribution.
- Investor: Retail, institutional, and high-net-worth individuals bidding for shares.
- Broker: Facilitates investor applications through platforms.
- Stock Exchange: NSE, BSE (India), or NYSE (US).
- SEBI: India’s regulator ensuring compliance and investor protection.
IPO Issuance Process Step-by-Step
The IPO journey follows a structured sequence:
- Preparation and Due Diligence
Company leadership, bankers, lawyers, and auditors compile financials, business details, and risk factors, and resolve legal issues. - Regulatory Approval
The company submits a Draft Red Herring Prospectus (DRHP) to SEBI (India) or equivalent regulators, detailing business operations, finances, fund usage, and risks. Regulators review and request clarifications. - Pricing and Book Building
Underwriters set a price band and gather bids from institutional and retail investors to gauge demand and fix the final issue price. - Allotment and Listing
Shares get allocated to successful bidders, excess bids refunded, and shares listed on exchanges for public trading.
What Happens on Listing Day
After IPO closure and allotment, shares debut on stock exchanges. Market forces then drive the price above or below the IPO price based on supply and demand.
Frequently Asked Question
What is an IPO?
An Initial Public Offering (IPO) is the process where a private company offers its shares to the public for the first time to raise capital, becoming a publicly traded entity listed on stock exchanges. Companies pursue IPOs to fund growth, repay debts, or provide liquidity to early investors. This primary market event differs from secondary market trading, where shares are bought and sold post-listing.
How to Apply for an IPO?
Investors need a demat account, PAN card, and UPI-linked bank account to apply via ASBA (Application Supported by Blocked Amount), blocking funds until allotment. Log into your broker’s platform, select the IPO, enter bid details like lot size and price, and approve the UPI mandate; shares will be credited to your demat post-allotment if successful. No trading account is required for the application, but check the minimum lot size specified in the prospectus.
What Happens After IPO Subscription?
Post-subscription (typically 3-7 days), the registrar determines allotment based on demand, publishing the basis of allotment online. Allotted shares credit to demat accounts before listing (usually T+6 days from close), with excess funds unblocked; unsuccessful applicants get refunds. Listing on BSE/NSE follows, enabling trading.
IPO Types and Pricing?
IPOs use fixed-price (set price upfront, full payment required) or book-building (price band, bids determine final price) methods. Retail investors apply within the band, often at cut-off, with quotas for retail (35%), QIBs (50%), and HNI (15%). SME IPOs have simpler rules for smaller firms.
