Why Identifying Red Flags Matters

Not every IPO is a good investment. Some companies time their IPOs to exit at peak valuations, hide problems behind complex disclosures, or simply aren't worth the asking price. Knowing what warning signs to look for can save you from significant losses.

Financial Red Flags

1. Declining Financial Performance

Watch for:

  • Revenue declining year-over-year
  • Shrinking profit margins
  • Increasing losses
  • Deteriorating return ratios (ROE, ROCE)

Where to Find: Financial Statements section of prospectus

2. Poor Cash Flow Quality

Warning signs:

  • Net profit significantly higher than operating cash flow
  • Persistent negative operating cash flows despite profits
  • Heavy reliance on external financing
  • Large working capital requirements

What It Means: Profits may not be "real" or sustainable

3. High Debt Levels

Concerns:

  • Debt-to-Equity ratio above 2 (industry-dependent)
  • Interest coverage ratio below 2
  • IPO proceeds primarily for debt repayment
  • Short-term debt financing long-term assets

4. Aggressive Accounting

Look for:

  • Revenue recognition policy changes before IPO
  • Unusual capitalization of expenses
  • Frequent auditor changes
  • Qualified audit opinions
  • Restated financials

Business Model Red Flags

1. Customer Concentration

High risk if:

  • Single customer provides >25% of revenue
  • Top 5 customers provide >50% of revenue
  • Key customer contracts expiring soon
  • Customers are related parties

2. Supplier Dependence

Concerns:

  • Single-source suppliers for critical inputs
  • No long-term supplier agreements
  • Supplier concentration in risk factors

3. Competitive Position

Warning signs:

  • Small player in fragmented market
  • No clear competitive advantage
  • Easily replicable business model
  • Facing disruption from new technologies

Governance Red Flags

1. Related Party Transactions

High risk if:

  • Significant transactions with promoter entities
  • Loans to/from related parties

3. Board Composition

Concerns:

IPO Structure Red Flags

1. High Offer for Sale (OFS)

Concerns when:

  • OFS exceeds 60% of total issue
  • Promoters selling significant stake
  • PE/VC investors exiting completely
  • Fresh issue is minimal

What It Means: Company may not need money; existing shareholders want to exit

2. Vague Use of Proceeds

Red flags:

  • Large "general corporate purposes" allocation (>25%)
  • Unclear expansion plans
  • Funds for undefined acquisitions
  • No specific timelines for capital deployment

3. Overpriced Valuation

Warning signs:

  • Premium justified only by "growth potential"
  • Comparison with irrelevant or foreign peers
  • Ignoring lower-valued comparable companies

Legal and Regulatory Red Flags

1. Pending Litigation

High concern if:

  • Material cases with potential adverse outcomes
  • Tax disputes of significant amounts
  • Criminal cases against company or management
  • Customer or employee lawsuits

2. Regulatory Issues

Market and Timing Red Flags

How to Use This Information

Red Flag Scoring

Create a simple system:

  • List all red flags identified
  • Categorize by severity (High/Medium/Low)
  • Any "High" severity red flag = Skip the IPO
  • Multiple "Medium" flags = Proceed with caution

Don't Ignore Red Flags

  • No IPO is worth taking excessive risk
  • There will always be other opportunities
  • Missing one IPO is better than losing money
  • FOMO is your enemy

Conclusion

Red flags don't always mean the IPO will fail, but they increase risk significantly. As a retail investor with limited access to management and due diligence resources, being conservative about red flags protects your capital. When in doubt, skip the IPO and wait for better opportunities. The market always provides new chances to invest.
