Full Definition
A 409A valuation (named for IRS Code Section 409A, which governs nonqualified deferred compensation) is an independent appraisal of a private company's common stock fair market value conducted by a qualified independent appraiser. The valuation is required because private company stock has no market price—the most recent preferred stock financing price reflects the price investors paid for preferred stock with superior rights, not the fair market value of common stock that employees receive through options. If stock options are granted at a price below fair market value, Section 409A imposes severe adverse tax consequences: immediate income recognition, a 20% penalty tax, and interest charges. A 409A valuation provides the "reasonable valuation method" safe harbor that protects against these penalties. 409A valuations use several approaches to determine common stock fair market value. The Option Pricing Model (OPM) treats the company's equity like a set of financial options and allocates value based on the cap table's priority structure, reflecting the economic reality that common stock sits behind preferred stock preferences. The Probability-Weighted Expected Return Method (PWERM) uses scenario analysis (IPO, M&A at various prices, dissolution) weighted by probability to estimate common stock value across scenarios. For early-stage companies with limited financial history, the Backsolve Method uses the most recent financing round's implied preferred stock value and works backward to common stock value using OPM. Most 409A valuations result in common stock values significantly below the most recent preferred financing price (typically 10-30% of preferred price), reflecting the economic subordination of common to preferred. 409A valuations must be refreshed at least every 12 months (or within 90 days of a "material event" that would affect the company's value—a new financing round, significant business acquisition, or material change in financial performance). Companies that delay 409A updates risk having option grants deemed below fair market value, exposing employees to Section 409A penalties. Prompt 409A completion after each financing round ensures that options can continue to be granted without delay and protects employees from inadvertent adverse tax treatment.
FAQs
How much does a 409A valuation cost and how long does it take?
Third-party 409A valuations typically cost $2,000-$8,000 for early-stage companies and $8,000-$20,000 for more complex later-stage companies with multiple financing rounds, complex capital structures, or significant revenue. Turnaround time is typically 2-4 weeks for standard engagements. Some specialized firms (Carta Valuations, Aranca, Advanced Valuation Group, Andersen, Big 4 valuation groups) provide 409A valuations as a standalone service. Companies that use Carta for cap table management often use Carta Valuations for integrated 409A service, which streamlines the process.
Can a company use a board-determined fair market value instead of a third-party 409A?
Yes—Section 409A provides multiple reasonable valuation methods, including board determination of FMV. However, this requires that the determination be made by a person with 'significant knowledge and experience or training in performing similar valuations'—which most company boards do not have. The third-party independent appraiser safe harbor provides much stronger protection against IRS challenge and is universally recommended for companies granting stock options. Board-determined valuations without qualified expertise are highly vulnerable to IRS scrutiny, particularly if the company later goes through an IPO or acquisition where the actual value becomes known.
