If your startup grants stock options, you will eventually receive a 409A valuation report. For many founders it is the first formal valuation document they have ever held, and it can run 30 to 60 pages of methodology, tables, and assumptions. Knowing what a 409A valuation report contains, and how to read it, helps you catch errors before they reach your auditor, your board, or the IRS.
This guide walks through each section of a typical 409A valuation report, the requirements a report must meet to earn safe harbor protection, and two worked examples showing how the final fair market value per common share is reached. It closes with a practical checklist for a 409A valuation report review, drawn from the questions Equirium Analytics' valuation team hears most often from founders and CFOs.
Key Takeaways
- A 409A valuation report sets the fair market value (FMV) of a private company's common stock, which becomes the minimum exercise price for stock options.
- Most reports follow the same structure: summary of conclusions, company and industry overview, valuation approaches, equity allocation, discount for lack of marketability, and final FMV.
- Safe harbor protection requires an independent, qualified appraiser and a valuation date no more than 12 months before the grant date.
- Early-stage reports commonly use the OPM backsolve; later-stage reports often use a PWERM or hybrid method.
- A material event, such as a new funding round, makes an existing report stale even if 12 months have not passed.
- Reviewing a report means testing the cap table, financial inputs, method choice, volatility, and DLOM, not just the final number.
- Errors in a 409A valuation report can trigger immediate income inclusion, a 20% additional federal tax, and interest for option holders.
What Is a 409A Valuation Report?
A 409A valuation report is an independent appraisal of the fair market value of a private company's common stock, prepared to comply with Section 409A of the US Internal Revenue Code. The FMV it concludes becomes the floor for the exercise price of stock options granted to employees, advisors, and contractors.
If options are granted below FMV, they are treated as deferred compensation. The option holder, not the company, bears most of the tax cost: income recognized at vesting, a 20% additional federal tax, and premium interest. That is why boards rely on 409A valuation reports and why auditors read them closely when testing stock-based compensation under ASC 718.
The report also matters beyond tax. The same FMV feeds the option expense in your financial statements, supports secondary transactions, and is often requested in due diligence by investors and acquirers.
What Is Included in a 409A Valuation Report?
While formats vary by provider, most 409A valuation reports follow a structure aligned with the AICPA Accounting and Valuation Guide on privately held company equity securities. The table below maps each section and what a reviewer should look for.
| Report section | What it contains | What to check |
|---|---|---|
| Summary of conclusions | Valuation date, FMV per common share, methods used, standard of value | Date and share class are correct |
| Company overview | History, products, stage, management, recent milestones | Facts match your current business |
| Industry and economic outlook | Market size, competitors, macro conditions at the valuation date | Outlook is relevant to your sector |
| Capitalization summary | Share classes, options, warrants, SAFEs, notes, preferences | Ties exactly to your cap table |
| Financial analysis | Historical results, projections, cash runway | Inputs match management's data |
| Valuation approaches | Income, market, and asset approaches with weighting | Reasons given for each method chosen or rejected |
| Equity allocation | OPM, PWERM, hybrid, or current value method | Assumptions for term, volatility, and scenarios |
| Discount for lack of marketability | DLOM percentage and supporting models or studies | Discount is supported, not assumed |
| Appendices | Comparable companies, OPM outputs, assumptions, appraiser credentials | Calculations are reproducible |
Summary of Conclusions
This opening page is the part most readers see. It states the valuation date, the FMV per share of common stock, the standard of value (fair market value), and the premise (going concern). A good summary also notes any material events considered and the methods relied on.
Valuation Approaches and Equity Allocation
This is the analytical core. The appraiser first estimates the total equity value of the company using one or more approaches, then allocates that value across preferred and common classes. Because preferred stock carries liquidation preferences, common stock is usually worth meaningfully less per share than the latest preferred price, and the allocation section explains exactly how much less and why.
Discount for Lack of Marketability
Common shares in a private company cannot be sold freely, so the report applies a DLOM to the marketable value per share. Typical DLOMs fall between roughly 15% and 35%, depending on the expected time to liquidity and volatility. The report should support the figure with put option models such as Finnerty or Chaffe, or with restricted stock studies.
409A Valuation Report Requirements for Safe Harbor
Treasury Regulation §1.409A-1(b)(5)(iv)(B) lists methods that are presumed reasonable, which shifts the burden to the IRS to prove the valuation was grossly unreasonable. To benefit from that presumption, a 409A valuation report should meet these requirements:
- Independent appraiser: the valuation is performed by a qualified appraiser who is independent of the company and its management.
- Qualified credentials: the appraiser holds relevant experience and credentials, such as CVA, ABV, ASA, or CFA, with a documented valuation track record.
- Timely valuation date: the valuation date is no more than 12 months before the option grant date.
- No intervening material event: no funding round, acquisition offer, major contract, or significant change in performance has occurred since the valuation date.
- Consideration of all relevant factors: the report addresses tangible and intangible assets, projected cash flows, market comparables, recent transactions, and control or marketability discounts.
- Consistent methodology: methods and assumptions are applied consistently with prior reports unless a change is explained.
A report that misses any of these points may still be reasonable, but the company loses the presumption and must defend the valuation on its own merits if challenged. For detailed understanding, one can read Equirium's blog on Safe Harbor in 409A.

409A Valuation Example: Seed-Stage Startup Using the OPM Backsolve
Consider an illustrative seed-stage SaaS company that closed a $4.0 million Series Seed round at $1.00 per preferred share three months before the valuation date. The company has 10.0 million common shares and 1.5 million options outstanding, with limited revenue and an expected exit horizon of about four years.
Because the seed round was an arm's-length transaction, the appraiser uses the option pricing method (OPM) backsolve. The total equity value is solved so that the model reproduces the $1.00 preferred price, and the remaining value is allocated to common stock.
| Step | Input or output | Value |
|---|---|---|
| Recent preferred price | Series Seed price per share | $1.00 |
| Key OPM assumptions | Term 4.0 years, volatility 65%, risk-free rate 3.9% | Applied |
| Backsolved total equity value | Solved to match the seed price | $9.0 million |
| Value allocated to preferred | 4.0 million shares × $1.00 | $4.0 million |
| Value allocated to common and options | Remaining equity value | $5.0 million |
| Marketable value per common share | Before discount | $0.43 |
| DLOM | Finnerty model, 4-year horizon | 30% |
| Fair market value per common share | $0.43 × (1 − 30%) | $0.30 |
The final 409A FMV of $0.30 per share is about 30% of the preferred price, a ratio commonly seen at the seed stage. Options granted at $0.30 or above within 12 months, and before any material event, sit within safe harbor. All figures in this 409A valuation example are illustrative.
409A Valuation Report Example: Series B Company Using a PWERM
Later-stage companies have clearer exit paths, so a 409A valuation report example at this stage usually looks different. Take an illustrative Series B company with $18 million in annual recurring revenue, growing steadily, with management actively discussing both acquisition interest and a longer-term IPO.
Here the appraiser uses a probability-weighted expected return method (PWERM). Each exit scenario is modeled separately, the common stock value under each scenario is discounted to the present, and the results are weighted by probability.
| Exit scenario | Probability | Present value per common share | Weighted value |
|---|---|---|---|
| IPO in 3 years | 20% | $4.80 | $0.96 |
| Strategic sale in 2 years | 50% | $3.10 | $1.55 |
| Downside or liquidation | 30% | $0.40 | $0.12 |
| Probability-weighted marketable value | 100% | $2.63 | |
| Less DLOM (20%) | ($0.53) | ||
| Fair market value per common share | $2.10 |
Notice the lower DLOM compared with the seed example. A shorter expected time to liquidity and a more mature business both reduce the marketability discount.
A complete 409A valuation report would show how each scenario value was derived, including the exit multiples, projected revenue at exit, and how liquidation preferences flow through the waterfall in each case. Many reports at this stage use a hybrid method, combining PWERM scenarios with an OPM for the uncertain outcomes.
How to Review a 409A Valuation Report
A 409A valuation report review should take the same view your auditor will. Work through these checks before the board approves the FMV:
1. Reconcile the Capitalization Table
Confirm every share class, option pool, warrant, SAFE, and convertible note matches your cap table as of the valuation date. Missing a SAFE or misstating a liquidation preference changes the allocation directly.
2. Test the Financial Inputs
Compare historical financials and projections in the report to the data you supplied. Projections should match the board-approved plan, not an older fundraising deck.
3. Check the Method Choice
The report should explain why it used a backsolve, PWERM, hybrid, or income approach, and why other methods were given less weight. A method that ignores a recent priced round needs a strong explanation.
4. Question the Key Assumptions
Look at volatility, term to exit, scenario probabilities, and the selected comparable companies. Volatility should come from a relevant peer set, and the term should reflect realistic exit timing.
5. Confirm the Valuation Date and Events
Make sure the valuation date reflects the latest material event and that nothing significant has happened since. If a term sheet is signed after the report date, you will likely need an update.

Common Red Flags in 409A Valuation Reports
Some issues appear repeatedly in 409A valuation reports that later face auditor pushback or need to be redone:
- Stale reports: relying on a report after a new funding round or acquisition offer, even within 12 months.
- Generic company descriptions: boilerplate overviews that suggest little company-specific analysis.
- Unsupported DLOM: a discount stated as a round number with no model or study behind it.
- Mismatched capitalization: share counts or preferences that do not tie to legal documents.
- Ignored transactions: secondary sales or recent rounds left out without explanation.
- Missing appraiser credentials: no statement of independence or qualifications, which weakens the safe harbor position.
Catching these issues early is far cheaper than repricing options or restating stock-based compensation expense after an audit.
Frequently Asked Questions
How long is a typical 409A valuation report?
Most 409A valuation reports run between 30 and 60 pages including appendices. Early-stage reports using a backsolve tend to be shorter, while later-stage reports with multiple scenarios and comparable company analysis are longer.
How often do 409A valuation reports need to be updated?
At least every 12 months, and sooner after any material event such as a priced funding round, acquisition offer, or major change in financial performance.
Who should prepare a 409A valuation report?
An independent, qualified appraiser with relevant credentials and experience, such as a CVA, ABV, ASA, or CFA charterholder. Independence is central to the safe harbor presumption.
Can a 409A valuation report be used for financial reporting?
Yes. Companies commonly use the same FMV for ASC 718 stock-based compensation expense, provided the report meets audit standards and the valuation date aligns with grant dates.
What happens if a 409A valuation report is wrong?
If options are granted below FMV, holders may face income inclusion at vesting, a 20% additional federal tax, and interest penalties. The company may also face withholding and reporting issues.
What should I send the appraiser for a 409A valuation report?
Typically your cap table, charter documents, financing agreements, historical financials, board-approved projections, and a summary of recent events or offers.
A 409A valuation report is more than a single number. Understanding its structure, its safe harbor requirements, and the assumptions behind the final FMV puts founders and finance teams in a stronger position with auditors, investors, and employees alike.
