Equity incentives can affect a company’s valuation through two separate channels: the compensation cost recognized in its financial statements and the potential dilution of existing shareholders’ ownership. Neither channel, by itself, determines whether the business is worth more or less. The outcome depends on the awards, the valuation method and whether the incentives help the company perform.
Start by asking which value you mean
“Company valuation” can refer to several different measures. An option’s accounting fair value, a private company’s common-stock fair market value, the price of preferred shares in a financing and the value of the whole operating business are not interchangeable. Equity incentives may be relevant to each, but they answer different questions.
| Measure | What it answers | How equity incentives enter |
|---|---|---|
| Share-based compensation expense | What compensation cost should be recognized under the applicable accounting framework? | Award fair value is measured for financial reporting. It is not the company’s total enterprise value. |
| Common-stock fair market value | What is a private company’s common stock worth for a particular purpose, such as setting an option strike price under U.S. 409A rules? | The appraisal concerns common stock, not necessarily the preferred shares sold to investors. |
| Fundraising valuation | What price will investors pay for a financing security? | The price is for the preferred shares offered, which may have rights that common stock does not. |
| Enterprise or equity value | What is the value of the operating business, or the value attributable to its equity? | Forecasts, compensation costs and claims on shares may affect the analysis, depending on the model. |
| Per-share value or diluted EPS | What value or earnings are attributable to each share on a stated share-count basis? | Potential shares from options and other instruments may change the denominator or ownership allocation. |
The applicable accounting basis also matters. The SEC’s Staff Accounting Bulletin No. 120 discusses U.S. public-company application of ASC Topic 718; the IFRS Foundation’s IFRS 2 overview describes the international standard for share-based payments. They should not be treated as one universal rulebook.
How compensation expense affects valuation
Under the U.S. public-company guidance discussed in SEC Staff Accounting Bulletin No. 120, share-based compensation cost is recognized at fair value. For options, estimating that fair value involves assumptions rather than simply reading the eventual stock price. The SEC discussion identifies inputs such as expected volatility, expected term and the current price of the underlying share; option terms and employee exercise behavior can affect the expected-term estimate.

This is an accounting measurement of compensation, not a direct measurement of enterprise value. Recognized expense can reduce reported earnings, and an analyst who values a business using earnings or cash-flow forecasts needs to understand how compensation is treated in those forecasts. A model that already accounts for the economic cost through forecasts should not add the same cost a second time through another adjustment.
The SEC guidance says an outside third party is not always required to perform the valuation, but the work should be done by someone with the requisite expertise. Those measurement assumptions concern award fair value; they do not establish that granting options increases or decreases the total value of the company by a fixed amount.
Rank #2
How options can dilute shareholders
Options give holders the right, subject to their terms, to acquire shares. If options are exercised or otherwise included in a diluted-share analysis, existing owners may hold a smaller percentage of a larger share base. That is a change in ownership claims and per-share allocation; it does not automatically mean the operating business itself has lost value.
The IFRS Foundation’s IAS 33 overview defines dilution in earnings per share in terms of a potential reduction in EPS or increase in loss per share from assumed conversion, option or warrant exercise, or shares issued under specified conditions. Accordingly, an investor should check whether a reported per-share figure uses basic or diluted shares and what instruments are included. “Dilution” without a stated share-count convention is incomplete.
Valuation methods can incorporate options in different ways. A 2005 Journal of Accounting Research study examines a warrant-pricing approach for incorporating employee options and their dilution into equity valuation. In that study’s model, estimated bias was larger for firms that were heavy users of employee options, smaller, R&D-intensive or had broad-based plans. Those are findings from a specific model and study, not a current market-wide estimate or a universal adjustment to apply to every company.
Why equity incentives may help or hurt the business case
Equity awards may help a company recruit and retain employees by giving them a stake in future outcomes. If the awards support execution and growth, that could contribute to business performance. But the existence of an incentive plan does not prove that it caused better performance, nor does accounting expense or dilution alone establish the net effect on value.
Rank #4
The sources available here do not establish a universal causal estimate of how much equity incentives add to or subtract from company valuation. The appropriate conclusion is conditional: assess the compensation cost, the potential share claims and the business rationale separately, then use assumptions that are consistent with the valuation method.

For a U.S. private company, Carta describes a 409A valuation as an independent appraisal of the fair market value of common stock, used to determine the minimum strike price for employee stock options. A fundraising valuation, by contrast, sets the price investors pay for preferred shares, which may carry rights that common stock does not. Carta’s founder’s guide to 409A valuations, published August 4, 2026, explains this distinction. These are different securities and purposes, so the two figures need not match. The U.S. 409A framework should not be generalized to every country.
Best Value
Carta also describes its own practice of using 409A reports as an input to ASC 718 stock-based compensation expense calculations and says auditors review methodology, support for inputs and the reasonableness of the common-stock conclusion. That is a provider’s account of its service, not an independent survey of all valuation practices; see Carta’s description of its valuation practice, published October 11, 2024.
Quick Recap
A practical way to evaluate equity incentives in a valuation
- Name the target. Decide whether the question concerns award expense, private common-stock value, a financing price, enterprise value, equity value or value per share.
- Identify the security and purpose. Distinguish employee options, common shares, preferred shares and the whole business; state the jurisdiction and accounting framework where relevant.
- Check the accounting treatment. Determine how share-based compensation is reflected in reported earnings or forecast cash flows under the applicable reporting basis.
- State the share-count basis. Specify whether the analysis uses basic or diluted shares and how options or other potential issuances are handled.
- Prevent double counting. If the model already reflects compensation costs or option claims in one place, do not charge for the same economic effect again through another adjustment.
- Assess the business rationale separately. Consider what hiring, retention or performance objective the awards are meant to support, without assuming a universal valuation premium.
