Common IPO Red Flags to Avoid

Not every IPO is launched mainly to fund growth. In some cases an IPO works primarily as an exit for early owners, shifting operational and financial risk from private sponsors onto public market participants. Checking filings for these six structural red flags helps you spot those deals.

1. Heavy Secondary Selling by Key Insiders

A primary offering issues brand-new shares; the proceeds go onto the company's balance sheet to hire talent, build infrastructure, and scale revenue. A secondary offering sells existing shares; the capital leaves the company and goes directly to the selling executives or funds. When a large portion of the offering consists of secondary shares, it can signal that the people with the deepest knowledge of the company's prospects are prioritizing their own liquidity over reinvestment in the business.

2. Dual-Class and Multi-Class Voting Disparities

Many technology and consumer companies go public with tiered share classes:

• Class A Common Stock: Sold to the public, carrying 1 vote per share (or zero votes).
• Class B / Class C Common Stock: Retained by founders and insiders, carrying 10 to 20 votes per share.

This structure weakens accountability to outside shareholders. Even if public shareholders purchase 80% of the economic equity, a founder holding high-vote shares can retain control over board elections, executive pay, and strategic decisions, leaving outside shareholders with little recourse if performance deteriorates.

3. "Adjusted EBITDA" Gymnastics

Unprofitable companies sometimes create custom non-GAAP metrics that make cash burn look smaller than it is:

• Community-Adjusted EBITDA / Contribution Margin: Stripping out core everyday expenses—such as office leases, customer service staffing, baseline marketing, or executive stock compensation—which can create an impression of operational profitability that the underlying business has not earned.
• If a company claims positive Adjusted EBITDA but GAAP operating losses continue to widen while operating cash flows remain negative, the underlying business is still burning cash.

4. Excessive Pre-IPO Debt & Dividend Recaps

When a company backed by private equity goes public, scrutinize the balance sheet. Sometimes the private equity sponsor has the portfolio company take on substantial high-yield debt to pay the sponsor a special pre-IPO cash dividend. If the IPO proceeds are then used mainly to repay that debt, the business may be left with little new capital for growth.

5. Severe Customer or Platform Concentration

If an enterprise software firm relies on one customer for 25% of annual revenue, or an e-commerce brand derives 85% of gross merchandise volume from an algorithmic feed on a single third-party platform (such as TikTok or Amazon), the business carries a serious dependency. The loss of that single client or an unannounced algorithm change can sharply cut forward earnings.

6. Tiered and Accelerated Lockup Loopholes

Be wary of lockup structures containing acceleration clauses where institutional funds or venture groups are permitted to sell tranches of stock early based on temporary stock price spikes. These arrangements can leave later buyers exposed when insiders sell into a short-lived rally.
