IPO Process

An Initial Public Offer (IPO) is the primary market mechanism through which an unlisted company issues new equity shares or offers its existing shares for sale to the public for the first time. Upon completion, the company transitions into a publicly traded listed entity on recognized stock exchanges. Within the Capital Market Regulation framework of the Indian economy, the Securities and Exchange Board of India (SEBI) governs this entire pipeline. SEBI updates the regulatory baseline via the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018 (ICDR Regulations), amended through the major 2025 and 2026 cycles, to enforce systemic transparency, balance investor access, and minimize pricing manipulation.

Dual Pathways to a Mainboard IPO

To ensure that speculative or financially weak entities do not exploit public capital, SEBI mandates two separate structural entry routes for issuers attempting a mainboard listing.

The Profitability Route (Regulation 6(1))

This is the standard baseline route for companies with established operational histories. Issuers must satisfy three strict financial metrics simultaneously:

• Net Tangible Assets: Minimum of INR 3 Crore in each of the preceding three full financial years (of which not more than 50% is held in monetary assets).
• Operating Profitability: Minimum average operating profit (EBITDA) of INR 15 Crore during any three of the preceding five financial years, with at least INR 1 Crore achieved in two of the preceding three financial years.
• Net Worth: Minimum of INR 1 Crore in each of the preceding three full financial years.

The QIB Alternative Route (Regulation 6(2))

If a fast-growing technology start-up or a capital-intensive business cannot satisfy the historical net tangible asset or operating profit criteria of Regulation 6(1), it is not barred from public markets. Instead, SEBI allows entry via the QIB Route on one core structural condition:

• Compulsory Institutional Allocation: At least 75% of the net offer size must be compulsorily allotted to Qualified Institutional Buyers (QIBs). If the issue fails to meet this institutional demand threshold, the entire IPO is cancelled and funds are refunded.

The Step-by-Step Chronology of the IPO Process

The corporate journey of executing a public issue follows a rigid procedural pipeline monitored continuously by SEBI, merchant bankers, and registrar transfer agents (RTAs).

Appointment of Intermediaries

The issuer appoints an independent, SEBI-registered Book Running Lead Manager (BRLM), who acts as the merchant banker and structural anchor of the issue. Simultaneously, underwriters, legal counsels, syndicates, and an RTA are institutionalized via legal mandates.

Dematerialization Mandate

To eliminate transactional delays and settlement risks, SEBI guidelines mandate that before the draft documents are submitted, the entire pre-IPO shareholdings of promoters, promoter groups, selling shareholders, directors, key managerial personnel (KMPs), and institutional investors must be fully converted into dematerialized electronic form with NSDL or CDSL.

Filing the Draft Red Herring Prospectus (DRHP)

The BRLM drafts the DRHP, a comprehensive disclosure document capturing company financials, business operations, material litigations, promoter track records, and sector-specific risk factors.

Review and Public Notice

• Submission: The DRHP is filed concurrently with SEBI and the chosen stock exchanges (BSE/NSE).
• Public Scrutiny: The document is made available on the SEBI portal for at least 21 days for public comments.
• SEBI Observations: SEBI reviews the disclosures, issues a series of directives or modifications, and provides its formal “Observations” clearance. This clearance remains valid for a strict one-time duration of 12 months.

The Digital Abridged Prospectus Framework

Under the operational guidelines, issuers are barred from packing essential summaries into long, unreadable multi-page documents. The traditional physical offer summary has been replaced by a mandatory 12-section Draft Abridged Prospectus.

• This condensed summary carries localized strict word-count limits (100–500 words per functional category, such as primary business details or related party transactions).
• BRLMs must embed a functioning QR code on every physical and digital bid application form. Scanning this code takes the retail investor directly to the digital abridged prospectus hosted on the exchange servers.

Filing the Red Herring Prospectus (RHP) and Price Band Determination

Once SEBI’s observations are integrated, the document is updated into the Red Herring Prospectus (RHP), which does not contain the final share price but outlines either a floor price or a specific price band (where the cap price cannot exceed 120% of the floor price). The RHP is formally registered with the Registrar of Companies (RoC) at least three days before the bidding window opens.

Bidding, Anchor Allocation, and Price Discovery

• The Anchor Allocation Window: One day prior to the formal opening of the public issue, the anchor investor bidding window opens. To broaden internal market stability, SEBI allows up to 40% of the public issue to be reserved for anchor investors. Within this institutional allocation, 33% is explicitly reserved for domestic mutual funds.
• The Public Bidding Window: The IPO is opened to the public for a standard period of three to five working days. Bids are submitted electronically through the book-building process.
• Pre-IPO Transaction Disclosures: To prevent information leakages during the bidding phase, companies must report any pre-IPO share transactions executed by the promoter group to the exchanges within 24 hours of occurrence.

Allotment and the Accelerated Settlement Cycle

• Price Finalization: Based on the cumulative demand recorded in the electronic bidding book, the BRLMs and the issuer determine the final discovery price. The final prospectus is then registered with the RoC.
• ASBA Allocation Framework: All retail and institutional bids must be processed via Application Supported by Blocked Amount (ASBA) or verified UPI block facilities. Funds never leave the investor’s bank account during the application phase; they are merely blocked by the self-certified syndicate bank (SCSB). Capital is debited only to the extent of actual share allotment, eliminating refund delays.
• T+3 and T+1 Listing Benchmarks: India mandates a compressed T+3 settlement timeline, meaning the company must complete share allotment and achieve formal listing on the stock exchanges within three working days from the closure of the bidding window.

Share Allocation Architecture and Quotas

To balance capital access among diverse investor segments, SEBI mandates proportional reservations based on the route chosen for listing.

Post-Listing Regulatory Controls and Lock-In Periods

To prevent promoters and early-stage investors from pumping share prices through an IPO and immediately abandoning the firm, SEBI enforces structural lock-in controls post-listing.

Promoter Share Contribution

Promoters must maintain a Minimum Independent Contribution of at least 20% of the post-issue paid-up capital of the corporation.

• Lock-In Rules: This core 20% promoter holding is locked for a period of three years from the date of listing. Any promoter holding exceeding this 20% baseline is locked for a period of one year.

Non-Promoter Share Lock-In

All pre-issue venture capital funds, alternative investment funds (AIFs), and private equity shares are locked in for a period of six months to one year from listing, subject to specific regulatory exemptions.

Special Pledged Share Facility

For pre-issue non-promoter shares that carry contractual bank pledges or institutional liens (making mechanical lock-ins impossible), depositories can mark the underlying demat accounts directly as “non-transferable”. This protects the lending bank’s security interests while maintaining market compliance, avoiding the need for complex pledge releases during the IPO process.

Capping General Corporate Purposes (GCP)

To prevent firms from raising vast public sums without defined capital layouts, SEBI restricts the allocation of IPO proceeds under the “General Corporate Purposes” line item to a maximum of 15% of the total issue size or INR 10 Crore, whichever is lower. These funds cannot be diverted toward basic corporate acquisitions or organic asset buy-outs.

Constitutional and Macroeconomic Trivia for UPSC Prelims

• Constitutional Allotment: The regulatory oversight of public issues, primary capital raisings, stock exchanges, and financial markets is classified under the Union List (List I) of the Seventh Schedule to the Constitution of India, specifically governed under Entry 90.
• Green Shoe Option: SEBI allows issuers to use a Green Shoe Option—a financial mechanism that permits the stabilization of post-listing share prices. The company can issue up to 15% additional shares beyond the stated IPO size to counter speculative volatility on the debut trading day.
• The Mainboard vs. SME Platform Split: Small and Medium Enterprises (SMEs) bypass mainboard regulations by listing on the BSE SME or NSE Emerge platforms. These listings require lower net worth figures and do not undergo direct SEBI screening. Instead, the respective stock exchanges review the offer documents, and the minimum application ticket size is set significantly higher (typically INR 1 Lakh) to keep out small, retail investors.
• The UPI Category Identifiers: To stop payment manipulation and digital phishing fraud during online IPO bidding, SEBI utilizes category-specific bank suffixes embedded within validated UPI handles. Investors can cross-verify whether their transaction routes through a verified intermediary handle using the “SEBI Check” toolkit on the SaaRTHI application.
