Why IPO Valuation Matters

Valuation determines whether an IPO is attractively priced or overpriced. Even a great company can be a poor investment if bought at an excessive price. Understanding valuation methods helps you make informed decisions and avoid overpaying.

Key Valuation Methods

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

The most common and easily understood valuation method.

Formula

P/E Ratio = Issue Price / Earnings Per Share (EPS)

How to Use

  • Calculate IPO P/E using the issue price and last year's EPS
  • Compare with listed peers' P/E ratios
  • Consider growth rates when comparing

Example

If IPO price is ₹500 and EPS is ₹25:

P/E = 500/25 = 20x

If peers trade at 15x, the IPO is at a premium. But if IPO company is growing faster, some premium may be justified.

Limitations

  • Doesn't work for loss-making companies
  • Can be manipulated through accounting
  • Ignores debt levels

2. EV/EBITDA

Enterprise Value to EBITDA - useful for comparing companies with different capital structures.

Formulas

  • Enterprise Value (EV) = Market Cap + Debt - Cash
  • EBITDA = Earnings Before Interest, Tax, Depreciation & Amortization
  • EV/EBITDA = Enterprise Value / EBITDA

For IPO

Market Cap at IPO = Issue Price × Total Shares Outstanding

Advantages

  • Works better for capital-intensive businesses
  • Accounts for debt (unlike P/E)
  • Less affected by accounting policies

Typical Ranges

  • Low: 5-8x (cyclical industries, low growth)
  • Medium: 8-15x (stable businesses)
  • High: 15-25x+ (high growth tech/consumer)

3. Price-to-Book (P/B) Ratio

Compares market price to book value of equity.

Formula

P/B = Issue Price / Book Value Per Share

Where It's Useful

  • Banks and financial institutions
  • Asset-heavy companies
  • Companies with significant real estate

Interpretation

  • P/B < 1: Stock trades below book value (could be undervalued or troubled)
  • P/B 1-3: Reasonable for most companies
  • P/B > 3: Premium valuation, needs justification

4. Price-to-Sales (P/S) Ratio

Useful for loss-making or early-stage companies.

Formula

P/S = Issue Price / Sales Per Share

OR Market Cap / Total Revenue

When to Use

  • Startups and new-age tech companies
  • Companies not yet profitable
  • Industries where revenue matters more than current profits

Typical Ranges

  • Traditional businesses: 1-3x
  • Tech/growth companies: 5-15x+

5. Discounted Cash Flow (DCF)

The most fundamental valuation method, though complex.

Concept

Value = Present value of all future cash flows

Steps (Simplified)

  1. Project future free cash flows (5-10 years)
  2. Calculate terminal value beyond projection period
  3. Discount all cash flows to present using appropriate discount rate
  4. Sum of present values = Intrinsic value

Challenges for IPOs

  • Limited historical data for projections
  • Highly sensitive to assumptions
  • Requires advanced financial modeling

Comparable Company Analysis

The most practical approach for retail investors.

Steps

  1. Identify Peers: Same industry, similar size, similar business model
  2. Calculate Peer Multiples: P/E, EV/EBITDA, P/S for each peer
  3. Find Average/Median: Central tendency of peer valuations
  4. Compare IPO: Is IPO trading at premium or discount?
  5. Justify Difference: Any difference should be explainable

Example Analysis

CompanyP/EEV/EBITDARevenue Growth
Listed Peer A25x12x15%
Listed Peer B20x10x12%
Listed Peer C22x11x18%
Peer Average22x11x15%
IPO Company28x14x25%

IPO is at premium (28x vs 22x average), but has higher growth (25% vs 15%). Premium may be justified.

Valuation Red Flags

  • P/E significantly higher than all peers without clear reason
  • Valuation justified only by "future potential"
  • Comparisons to unrelated or foreign companies
  • Cherry-picked peer set in prospectus
  • Revenue multiple for profitable company (hiding something?)

Industry-Specific Considerations

Technology/SaaS

  • Revenue multiples often used
  • Look at ARR (Annual Recurring Revenue) growth
  • Customer retention metrics matter

Financial Services

  • P/B is primary metric
  • Consider ROE and asset quality
  • NBFCs typically trade at 2-4x book

Manufacturing

  • EV/EBITDA appropriate
  • Consider capacity utilization
  • Asset replacement value matters

Practical Tips

  • Use multiple valuation methods, not just one
  • Always compare with listed peers
  • Adjust for growth rate differences
  • Be skeptical of very high valuations
  • Remember: valuation is art, not exact science

Conclusion

Valuation is crucial for determining if an IPO offers good value. While no single method is perfect, using multiple approaches and comparing with listed peers provides a reasonable assessment. Remember that even at fair valuations, other factors like business quality and growth prospects matter. Don't let attractive valuations blind you to fundamental problems.
