Editorial Key Takeaways

This analysis is based on official Draft Red Herring Prospectus (DRED) filings, historical peer valuation multiples, and exchange data. Figures are audited for institutional accuracy.

When a promoter brings an IPO, their primary incentive is to price the issue at the highest multiple the market will absorb.

To protect your capital, you must independently evaluate whether an IPO leaves money on the table for incoming public shareholders.

1. The Core Valuation Metrics Explained

A. Price-to-Earnings Ratio (P/E)

$$ ext{Post-Issue EPS} = rac{ ext{Net Profit (PAT)}}{ ext{Pre-Issue Shares} + ext{Fresh Issue Shares}}$$

$$ ext{Post-Issue P/E} = rac{ ext{Upper Price Band}}{ ext{Post-Issue EPS}}$$

  • Benchmark: Compare Post-Issue P/E against the average P/E of listed industry peers. If an IPO asks for 45x P/E while established industry leaders trade at 30x with higher ROE, the issue is overpriced.

    • B. Enterprise Value to EBITDA (EV / EBITDA)

    $$ ext{Enterprise Value (EV)} = ext{Market Cap} + ext{Total Debt} - ext{Cash \& Bank Balances}$$

    $$ ext{EV/EBITDA Multiple} = rac{ ext{Enterprise Value}}{ ext{Annual EBITDA}}$$

  • Best for: Manufacturing, renewables, logistics, and capital-heavy infrastructure.

    • C. Price-to-Book Value (P/B)

    $$ ext{Post-Issue Book Value per Share} = rac{ ext{Net Worth} + ext{Fresh Issue Proceeds}}{ ext{Total Post-Issue Shares}}$$

    $$ ext{Price / Book} = rac{ ext{Upper Price Band}}{ ext{Post-Issue BVPS}}$$

  • Best for: Banking, NBFCs, and Housing Finance Companies (e.g. Bajaj Housing Finance).

    • 2. Three Accounting Red Flags to Audit in the RHP

    1. The Pre-IPO Profit Miracle: Look at the 3-year revenue and PAT trend in the RHP. If profit grew at 8% in Year 1, 10% in Year 2, and suddenly exploded by 120% in Year 3 (the pre-IPO year), scrutinize other income and depreciation adjustments.

    2. High Related-Party Transactions: Promoters transferring high-margin services to personal privately-owned LLPs.

    3. 100% OFS with Zero Fresh Capital: When existing private equity funds and founders take all cash out and inject zero rupees into the company balance sheet for future growth.
