What valuation methods are used in a 409A valuation?
Appraisers use three recognized approaches: the market approach (guideline public company multiples and M&A transactions), the income approach (discounted cash flow), and the asset approach (fair value of underlying assets less liabilities). For venture-backed companies, the most common method is the backsolve or prior transaction method, which infers enterprise value from a recent preferred stock financing round; practitioner surveys attribute over half of all 409A valuations to it. We select and combine approaches based on the company’s stage, capital structure, and available data.
When should a company refresh its 409A valuation?
At least annually, or sooner after a material event such as a new financing round, a major acquisition, or a substantial change in revenue. Continuing to grant options at an old strike price after value has moved can make those grants discounted deferred compensation under Section 409A, forcing repricing or cancellation. We recommend scheduling the refresh before the next planned option grant, not after.
What happens if stock options are granted below fair market value?
Recipients can face immediate income inclusion, a 20% additional federal tax, and interest penalties under Internal Revenue Code Section 409A. The company may then have to reprice or cancel the affected grants. This is why the fair market value must be set on or before the grant date using a contemporaneous, good-faith valuation rather than an informal board estimate or investor term sheet.
Does the IRS require a specific formula for 409A valuations?
No. The regulations require a reasonable application of a reasonable valuation method, and income, market, and asset approaches are all recognized. Blanket claims that revenue multiples are mandatory or that discounted cash flow is the only compliant method are incorrect. The safe harbor does expect a written valuation report prepared by someone with significant knowledge, experience, education, or training in valuation.
What separates a credible 409A report from a weak one?
A credible report documents the capital structure and the rights of each security class, then allocates value using a recognized model such as the Option Pricing Model (OPM) or the Probability-Weighted Expected Return Method (PWERM), reflecting liquidation preferences, conversion rights, and participation features. Weak reports divide enterprise value by fully diluted shares as if all classes were equal, which is far more likely to be challenged by auditors or the IRS.
