How IPO Price is Decided: The Mathematics Behind Valuation Bands

How does a company decide whether its shares should be priced at ₹100 or ₹1,000? Setting the issue price is an elaborate financial engineering process conducted by registered Merchant Bankers (Book Running Lead Managers or BRLMs).

1. The Role of Lead Managers and Merchant Bankers

Merchant bankers act as intermediaries between the issuing company and the investing public. They perform thorough due diligence on the company's financial books, draft the DRHP filed with SEBI, and propose valuation models that balance promoter valuation expectations with institutional investor appetite.

2. Top 3 Valuation Methodologies

• Discounted Cash Flow (DCF): Projects future free cash flows of the business over 5 to 10 years and discounts them to present value using the Weighted Average Cost of Capital (WACC).
• Price-to-Earnings (P/E) Multiple: Multiplies the company's EPS by the historical average P/E ratio of its industry peers.
• Enterprise Value to EBITDA (EV/EBITDA): Ideal for capital-intensive companies with high depreciation or varied capital structures.

3. Listed Peer Group Benchmark

If a new shoe manufacturer files an IPO, bankers compare its financial metrics directly with listed peers like Bata India and Relaxo Footwears. If peers trade at 40x P/E, the IPO is generally priced at a slight discount (e.g., 32x to 35x P/E) to leave an attractive upside margin for investors.

4. Institutional Roadshows and Anchor Bidding

One day prior to the public opening, the company opens bidding for Anchor Investors (large mutual funds, sovereign wealth funds, and marquee institutional buyers). The anchor book price confirms whether institutional smart money supports the upper price band.

When an issue leaves substantial value on the table, demand spills into the unofficial grey market premium market. Check current sentiment and daily listing estimates on our latest IPO GMP dashboard.
