For many companies preparing to go public, the focus naturally turns to growth metrics, financial readiness, and positioning the business for public investors. Yet one technical detail can quickly become a major issue late in the process: the company’s 409A valuation history.

During the IPO review process, the SEC closely examines equity grants and the valuations behind them. If that record does not align with the company’s expected IPO pricing, it can create a “cheap stock” problem, leading to delays, regulatory scrutiny, and uncomfortable disclosures. Treating 409A governance as a core part of your capital strategy, rather than simply a tax compliance requirement, can go a long way in supporting a smoother transition to life as a public company.

Moving Beyond the Annual Cycle

During quiet growth periods, an annual 409A valuation usually suffices. However, once a company enters the “IPO zone” (roughly 12–18 months before a potential listing), its value can change quickly, and valuations need to keep pace. Many companies adopt a quarterly 409A cadence in the final year before an IPO to ensure equity pricing reflects current business performance and market conditions.

Certain events should also trigger an immediate update, including banker bake-offs, the initial organizational meeting for the offering, filing the confidential S-1, closing a new funding round, or significant secondary share sales. These milestones often signal rapid shifts in company value. Waiting a full year to update fair market value (FMV) during this period can result in large valuation jumps that attract regulatory scrutiny.

Understanding the “Cheap Stock” Issue

During the IPO review process the SEC compares the midpoint of the expected IPO price range with the weighted-average exercise price of equity awards granted during the prior fiscal year and any subsequent interim periods. If the IPO price is significantly higher than those grant prices, the SEC may conclude that earlier 409A valuations understated the fair market value of the company’s common stock – referred to as “cheap stock”.

This often appears as a sharp increase in valuation, sometimes called “hockey-stick” growth, shortly before the IPO. When that happens, the company must provide clear documentation showing why earlier valuations were reasonable based on the information available at the time. The consequences can include additional costs, tax complications, and delays in the SEC review process. Because of this, many companies now proactively submit a standalone cheap stock letter explaining valuation changes and methodology before the SEC raises questions.

Methodology Matters More as the IPO Approaches

Valuation methodology becomes more crucial in the final stages before going public. Early-stage companies often rely on simpler approaches, but as an IPO becomes more likely, auditors and regulators typically expect methods that model potential exit scenarios.

The key requirement is that the valuation reflects economic reality and incorporates relevant market signals. The Probability-Weighted Expected Return Method (PWERM) is commonly used at this stage because it models potential outcomes such as an IPO, a sale, or remaining private.

Secondary share sales can also affect the analysis. If insiders or investors sell shares at prices above the latest 409A valuation, those transactions may indicate a higher fair market value that regulators expect to see reflected in the 409A.

Preparing Early Reduces IPO Risk

The most successful IPOs are those where the valuation history tells a consistent, defensible story of growth. Increasing valuation frequency, using robust methods like PWERM, and documenting the rationale behind each change helps ensure that story holds up under scrutiny.

Companies that prepare early can avoid costly corrections late in the process. When it is time to present the company to public investors, a well-documented and consistent 409A history helps ensure that valuation questions do not become the factor that slows the process down.
