409A Valuation FAQ and Guide

Learn what a 409A valuation is, how it works, and how a company may choose a 409A valuation firm.

1) What is a 409A Valuation?

Public companies are valued by the price their stock trades at in the market, but private companies need a valuation to determine the fair market value (FMV) of their equity. A 409A valuation also establishes the “strike price” (the price at which equity can be bought) that must be at or above FMV.

2) Why do private companies need a 409A valuation? 

Since 2004, a 409A valuation is required by law (IRS Section 409A was passed as part of the American Jobs Creation Act) if a private company issues equity or options. Non-compliance can have serious consequences. Undervaluing stock options can result in IRS penalties and lost compensation.

3) How much can a 409A valuation cost?

For many early-stage private companies, third‑party 409A valuations often fall in the low thousands of dollars. Costs can rise to multiples of those fees for later-stage companies or situations with increased complexity (depending on scope and provider) and frequency (where the 12 month IRS safe harbor no longer applies, such as IPO planning).

 

What drives pricing:

 

  • Company stage of development: Later-stage businesses with mature business models, complex market dynamics, and larger pools of stakeholders typically require more work.
  • Capital structure complexity: Multiple preferred classes, participating preferred, warrants/SAFEs/convertible notes, secondary transactions, or complex option plans generally increase effort.
  • Number of rounds and terms: More financing rounds and bespoke terms can require deeper modeling and allocation work.
  • Timing (“rush” requests): Expedited turnarounds frequently come with additional fees.
  • Audit readiness / documentation needs: scope-of-work increases when when you need audit-support workpapers or extra documentation beyond the 409A report.

4) How often should a private company do a 409A valuation?

Private companies may be required to obtain a 409A valuation before issuing first option grants to employees and shareholders and anytime there is a material event in the company’s lifecycle, like a fundraise or liquidity event (e.g., tender offer).

 

Some early-stage companies are advised to conduct a 409A valuation every 12 months, consistent with the typical “safe harbor” provided by the IRS (which deems the 409A valuation valid for that period).

5) What is 409A valuation safe harbor?

Proof that a company calculated a reasonable fair market value of its common stock. This will help ensure that the valuation will be accepted as valid by the IRS.

6) When do you need to update your 409A valuation?

A practical rule founders use is to update their 409A at least every 12 months or sooner after a material event (whichever comes first).

 

Common “material event” examples:

 

  • New financing round (priced equity round, meaningful SAFE/note conversion dynamics, or significant secondary activity)
  • M&A / IPO discussions or receiving a credible indication of interest
  • Major product or market milestone (e.g., launch, regulatory clearance, major partnership)
  • Significant performance change vs. plan (rapid growth, major customer win/loss, margin shift)
  • Material balance sheet changes (large cash infusion, debt, or liquidity events)
  • Major corporate actions (recaps, amendments to preferred terms, option plan changes that affect value)

7) Why might a private company hire a 409A valuation firm?

The labor-intensive nature of 409A valuations might be why some private companies choose a third-party provider (like Morgan Stanley at Work) to provide a thorough and independent 409A valuation. Relying upon a trusted 409A valuation provider may demonstrate both the competence and objective perspective that could satisfy IRS requirements for a private company’s safe harbor.

 

A 409A valuation may provide a private company with safe harbor and secure its ability to grant options and recruit during that period. The job of the 409A valuation provider is to do the heavy lifting on the valuation, provide an analysis that matches the narrative of the private company, help with the messaging to employees, and create a coherent valuation history. Perhaps most importantly, that provider should be absorbing the majority of the work so that the founders can focus on more important things, like building their company.

8) How is a 409A valuation typically calculated?

At a high level, a 409A valuation typically involves:

 

  1. Estimating the company’s enterprise value using one or more approaches (income-based, market-based, and/or asset-based methods depending on facts and stage).
  2. Allocating value across the company’s securities (preferred vs. common, different preferred series, options/warrants), reflecting each class’s rights and preferences.
  3. Determining common stock FMV and applying appropriate adjustments that may reflect private-company factors such as lack of marketability/illiquidity, as well as the specifics of the capital structure.

 

The conclusion provides a recommended FMV per share of common stock used to support option strike prices.

9) What are the most common 409A methodologies?

There is no universal formula to determine an appropriate value for an illiquid, non-controlling interest in a closely held company. Determination of value is a matter of judgment, which takes into consideration economic and market conditions, as well as investment opportunities that would be considered as alternatives to the interest being valued. The methods commonly used to value a closely held business include the following:

Income Approach

This approach focuses on the income-producing capability of a business. The income approach estimates value based on the expectation of future cash flows that a company will generate – such as cash earnings, cost savings, tax deductions, and the proceeds from disposition. These cash flows are discounted to the present using a rate of return that incorporates the risk-free rate for the use of funds, the expected rate of inflation, and risks associated with the particular investment. The selected discount rate is generally based on rates of return available from alternative investments of a similar type, quality, and risk.

Market Approach

This approach measures the value of an asset or business through an analysis of recent sales or offerings of comparable investments or assets. When applied to the valuation of equity interests, consideration is given to the financial condition and operating performance of the entity being appraised relative to those of publicly traded entities operating in the same or similar lines of business, potentially subject to corresponding economic, environmental, and political factors and considered to be reasonable investment alternatives. The market approach can be applied by utilizing one or both of the following methods:

 

  • Guideline Public Company Method (“GPCM”): This methodology focuses on comparing the subject entity to guideline publicly traded entities. In applying this method, valuation multiples are: (i) derived from historical or forecasted operating data of selected guideline entities; (ii) evaluated and / or adjusted based on the strengths and weaknesses of the subject entity relative to the selected guideline entities; and (iii) applied to the appropriate operating data of the subject entity to arrive at a value indication.
  • Guideline Transaction Method (“GTM”): This methodology utilizes valuation multiples based on actual transactions that have occurred in the subject entity’s industry or related industries to arrive at an indication of value. These derived multiples are then adjusted and applied to the appropriate operating data of the subject entity to arrive at an indication of value.
  • Backsolve Method: By considering the sale price of shares in a recent financing, the equity value can be “back-solved” using an option pricing model that considers the company’s capital structure and the rights of the preferred and common stock shareholders.

Cost Approach

This approach measures the value of an asset by the cost to reconstruct or replace it with another of like utility. When applied to the valuation of equity interests in businesses, the value is based on the net aggregate FMV of the entity’s underlying individual assets.  The technique entails a restatement of the balance sheet of the enterprise, substituting the FMV of its individual assets and liabilities for their book values. The resulting approach is reflective of a 100.0% ownership interest in the business. This approach is frequently used in valuing holding companies or capital-intensive firms. It is not necessarily an appropriate valuation approach for companies having significant intangible value or those with little liquidation value.

10) What information does a private company need to provide for a 409A valuation?

Depending on the provider, private companies may need to provide a mix of qualitative and quantitative data. Data points, such as revenue, net income, projected growth, and company/industry risk may be used to make this determination.

11) What can happen if a company grants options using an outdated or unsupported 409A valuation?

If options are granted with an exercise price below FMV (e.g., due to a stale or unsupported valuation), significant adverse tax consequences can apply to recipients under Section 409A, potentially including:

 

  • Immediate income inclusion (even before exercise in some cases)
  • Additional taxes and penalties
  • Interest charges

 

Beyond tax exposure, it can create audit issues, complicate financing or capital raise events, even delay IPO and/or M&A planned exits. The practical takeaway is: keep valuations current and well-supported.

12) Why may common stock be valued differently than preferred stock in fundraising rounds?

Fundraising rounds typically price preferred stock, which often comes with rights that common stock does not have, such as:

 

  • Liquidation preferences
  • Dividends (sometimes)
  • Protective provisions / veto rights
  • Anti-dilution protections
  • Seniority in liquidation

 

A 409A valuation is focused on the FMV of common stock for option strike pricing. Because preferred has different economics and downside protection, its price can be higher than the implied value of common—even at the same time and in the same company.

13) Does a 409A valuation apply only to employees, or also advisors/contractors?

It’s not limited to employees and needs to be considered if a private company grants equity compensation to service providers, directors, advisors, and certain contractors. Having defensible FMV support for the exercise/strike price remains important for compliance and risk management.

14) How long does a 409A valuation with Morgan Stanley at Work take?

The 409A valuation process has a few stages, which include:

Kickoff (Initial data review)

The valuation team will conduct a thorough review of the data submitted by your startup.

Analysis (Management call)

With pertinent questions in hand, we’ll schedule a call with your team to collect information regarding your business (status and plans), comparable companies, potential risks, and industry insights to be used in the analysis.

Model (Develop draft report and exhibits)

Once we have a clear picture of the business, we’ll complete the analysis and generate the draft report and exhibits.

Review (Review analysis)

We then present the report for your review, collect feedback and make any necessary adjustments.

Finalize (Issue final valuation opinion)

After all questions are answered and assumptions vetted, we’ll present the finalized report.

 

Once the due diligence process has been completed (information has been provided by the startup for the kickoff), the valuation process generally takes a couple of weeks.
