409A Valuation vs VC Valuation: Why Your Investors' Number Isn't Your Common Stock's

How this page fits with our other guides: This article is about the venture side of the comparison: how investors price a round and how a 409A treats that price. The per-share mechanics of why common stock is worth less than preferred, with worked discount examples, are in 409A price vs preferred price. The difference between “409A” and “fair market value” as terms is covered in 409A valuation vs fair market value. We link to those pages rather than repeat them.

What is the difference between a 409A valuation and a VC valuation?

A VC valuation is the price a venture investor negotiates for newly issued preferred stock, expressed as a pre-money or post-money figure for the whole company. A 409A valuation is an independent appraisal of the fair market value of one share of common stock, used to set option exercise prices. One is a deal price; the other is a tax-compliance appraisal.

The two numbers differ in almost every dimension that matters. They value different securities, they serve different purposes, they are produced by different people with different incentives, and they are governed by different rules. A VC valuation is the outcome of a negotiation between a company that wants the highest price and least dilution and an investor that wants the best return for the risk. A 409A valuation is an opinion of value prepared to satisfy Treasury Regulations Section 1.409A-1(b)(5)(iv)(B), which requires the reasonable application of a reasonable valuation method.

The confusion comes from the way the VC number is quoted. Founders and the press talk about “a $150 million valuation,” which sounds like the value of the company and therefore of every share in it. It is neither. It is the price of one share of the new preferred series multiplied by the number of fully diluted shares, a figure that assumes every common share, option and older preferred share is worth exactly what the newest investor paid. That assumption is what a 409A does not make.

How Venture Investors Arrive at a Valuation

A VC valuation is rarely the output of a formal appraisal. It is a price that clears a negotiation, and investors use a handful of tools to decide what they are willing to pay:

• The venture capital method. The investor estimates what the company could be worth at exit, divides by the return multiple the fund needs to justify the risk, and adjusts for expected future dilution. If a fund believes a company could sell for $1.5 billion in seven years and needs a 10x return on this check, it can justify a post-money of roughly $150 million before dilution from later rounds.
• Ownership targets. Many funds aim to own a set percentage after their investment, often 15% to 25% for a lead investor in an early round. Combined with the amount the company needs to raise, that target effectively sets the post-money: raise $30 million for 20% ownership and the post-money is $150 million.
• Comparable rounds. Investors look at what similar companies at a similar stage and growth rate raised at, often expressed as a multiple of annual recurring revenue for software companies.
• Competition and momentum. When several funds want into a round, the price goes up. When the company has little runway and few options, it goes down. Neither fact changes the business itself.

The result is a single negotiated per-share price for the new preferred stock, together with a term sheet that sets the preferred's rights. Those rights, not just the price, are what the investor is paying for.

Pre-Money, Post-Money and the Headline Number

Three related figures are often used interchangeably in the 409A vs venture valuation conversation. They should not be:

• Price per share. The amount investors pay for each share of the new preferred series. This is the only number in the term sheet that is actually paid.
• Post-money valuation. The price per share multiplied by the fully diluted share count after the round, usually including all outstanding common and preferred stock, outstanding options, and the unallocated option pool.
• Pre-money valuation. The post-money minus the new money invested.

Two common features make the headline post-money even less like the value of common stock. The first is the option pool shuffle: investors frequently require the option pool to be enlarged before the round and counted in the pre-money share count. That lowers the price per share for a given pre-money, so the dilution falls on existing holders rather than the new investor, and the “effective” pre-money value of existing shares is lower than the headline suggests. The second is the SAFE valuation cap. A post-money SAFE with a $20 million cap is sometimes described as a “$20 million valuation,” but no one has paid a per-share price for stock at that cap; it is a ceiling on a future conversion price. How a 409A treats SAFEs is covered in our guide to 409A valuations after a SAFE.

Why is my 409A valuation lower than my VC valuation?

Because the VC valuation prices preferred stock and then applies that price to every share, while the 409A values common stock directly. Preferred carries liquidation preferences, seniority and protective rights that common lacks, and private common cannot be readily sold. A 409A reflects both, so it lands below the round price per share.

The VC framing adds a further reason that is easy to miss: the investor's price is set by what the investor receives across all outcomes, and in the many outcomes where the company sells for less than the headline, preferred stock is paid first. A venture investor paying $6.00 per share for a 1x liquidation preference is buying a security that returns its money in a modest exit and converts to common only in a large one. Common stock gets what is left. The headline post-money does not show that asymmetry. A 409A has to.

There is no single ratio between the 409A value of common and the round price. It depends on the stage, the size of the preferences relative to the company's value, the expected time to exit, volatility, and the marketability discount. Our preferred price guide walks through typical ranges and the individual discounts.

How a 409A Uses the VC Round: The Backsolve

A 409A does not ignore the VC valuation. Treasury Regulations Section 1.409A-1(b)(5)(iv)(B)(1) lists recent arm's-length transactions involving the company's stock among the factors a reasonable valuation method considers, and a recent priced round between a company and unrelated investors is often the best evidence of value available. The question is how to use it.

The standard answer is a backsolve. The appraiser builds an allocation model of the full capital structure, typically an option pricing model, with every series' liquidation preference, seniority, participation and conversion terms. Then the appraiser solves for the total equity value at which the model says the newly issued preferred share is worth exactly the price the VC paid. That total is the round's implied equity value. The same model then shows what a share of common stock is worth at that equity value, before a discount for lack of marketability is applied.

The implied equity value from a backsolve is usually below the headline post-money, because the backsolve gives the preferred stock credit for its preferences rather than assuming every share is equal. That is the core of the 409A valuation vs VC valuation reconciliation: the appraiser accepts the investor's price as real evidence, but accepts it as the price of preferred stock, with preferred stock's rights.

How Deal Terms Change the Gap: Structure vs Price

Because the backsolve models the preferred's rights, two rounds at the same headline post-money can produce very different 409A results. Investors sometimes accept a higher price per share in exchange for stronger terms, a trade-off known as structure for price. The headline goes up; the value left for common goes down.

Consider an illustrative company with 25 million fully diluted shares: 13 million common shares and options, 7 million Series A preferred shares issued at $2.00 with a 1x non-participating preference, and 5 million new Series B preferred shares sold at $6.00 per share for $30 million. The headline post-money is $150 million in both cases below. The only difference is the Series B liquidation preference. The figures come from a simplified option pricing model backsolve with a three-year expected term, 60% volatility, a 4% risk-free rate, Series B senior to Series A, options treated as common, and a 30% marketability discount.

Adding half a turn of preference to the new series, with no change to the price or the headline, cuts the implied equity value by more than a third and the common stock value by more than half. Real 409A models are more detailed than this sketch, and the inputs above are assumptions, but the direction is reliable. Other investor-friendly terms push the same way: participating preferred, cumulative dividends, redemption rights and ratchets all shift value from common to preferred. Terms that are friendlier to common, such as a plain 1x non-participating preference, tend to narrow the gap.

This is also why a founder should read the term sheet, not just the headline, before guessing what the next 409A will show. A rich valuation achieved with heavy structure often produces a lower common stock value than a modest valuation on clean terms.

409A vs Investor Valuation: Side-by-Side Comparison

The table below compares the two numbers, plus a third that founders sometimes overlook: the fair value at which a venture fund carries its investment in your company on its own books.

The fund mark is worth knowing about because investors sometimes mention it in board meetings. It is a fair value measurement of preferred stock for financial reporting, prepared with methods similar to those in a 409A, but for a different holder, security and standard. It is not a substitute for a 409A, and it is not expected to equal either the round price or the value of common.

Does a higher VC valuation increase my 409A?

Usually, yes. When a 409A calibrates to a new round, a higher price per share generally produces a higher implied equity value and a higher common stock value. But the effect is not one-for-one: deal terms, the size of preferences relative to value, and the marketability discount all shape how much of an up-round reaches common.

Three practical consequences follow for founders and CFOs:

• Grant before or after the round, not during it. A signed term sheet for a new priced round is generally information that may materially affect value. Options granted after that point on an old 409A risk being priced below fair market value. Our guide to 409A valuations after a funding round covers timing in detail.
• Expect the strike price to rise. An up-round usually raises the strike price for the next set of grants. That is a recruiting cost, but it is the trade-off for the company being worth more.
• Down rounds work in reverse. A lower price per share, or the same price with heavier terms, usually lowers the 409A, which can make new grants cheaper and may support an option repricing. See our guide to 409A valuations in a down round.

Why a VC Round Can't Replace an Independent 409A

Some founders ask whether the round itself is enough: investors did diligence, agreed a price, and wired money, so why pay an appraiser? The answer lies in what Section 409A requires and what protects the company.

A stock option is exempt from Section 409A only if its exercise price can never be less than the fair market value of the underlying stock on the grant date, under Treasury Regulations Section 1.409A-1(b)(5)(i). The round price tells you what preferred stock is worth to the investors who bought it, not the fair market value of common. Using the preferred price as the strike price is permitted, since it would generally be above the fair market value of common, but it overprices every grant and weakens the incentive the options are meant to provide. Discounting the preferred price by a rule-of-thumb percentage is not a reasonable valuation method on its own, and it earns no presumption of reasonableness.

The stronger reason is the presumption of reasonableness. Under Section 1.409A-1(b)(5)(iv)(B)(2), a valuation by a qualified independent appraiser, as of a date no more than 12 months before the grant, is presumed reasonable, and the IRS can overturn it only by showing it is grossly unreasonable. The regulations also offer a presumption for a written valuation of an illiquid startup prepared by a person with significant knowledge and experience, and for certain binding formula prices. A VC round on its own qualifies for none of these. Without a presumption, the company bears the burden of proving its value was reasonable if the IRS challenges it. Options found to have been priced below fair market value are generally treated as deferred compensation that fails Section 409A, and option holders can face income inclusion as the options vest, an additional 20% federal tax, and premium interest, with state taxes possibly applying as well. Our 409A safe harbor guide explains each method.

Investors know this, which is why priced rounds almost always come with a closing deliverable or a near-term expectation that the company will refresh its 409A. Our guide for VC-backed startups covers what investor board members typically expect from the process, and how auditors and VCs review a 409A explains what they look for in the report.

When the VC Valuation and the 409A Converge

The gap between the VC valuation and the 409A is widest early, when preferences are large relative to the company's value and an exit is many years away. It tends to narrow as the company matures, for three reasons:

• Preferences shrink relative to value. When the company is worth many times the total liquidation preference, preferred is likely to convert in most outcomes, and common and preferred share value more equally.
• The expected time to liquidity falls. As an IPO or sale approaches, the marketability discount on common shrinks and appraisers give more weight to exit scenarios in which every class converts.
• A public price replaces the appraisal. After an IPO, fair market value comes from trading on an established securities market, and the distinction disappears for new grants. Our article on 409A valuation vs IPO price covers that last stretch.

Rapid convergence ahead of an IPO can also draw scrutiny. If grants made in the year before an offering carry strike prices far below the IPO price, auditors and regulators may ask how the common stock value moved so quickly. A well-documented series of 409A valuations, each calibrated to the financing and exit evidence available at the time, is the answer.

The Bottom Line on 409A Valuation vs VC Valuation

The 409A valuation vs VC valuation gap is not a sign that either number is wrong. A VC valuation is a negotiated price for preferred stock, quoted as if every share were preferred. A 409A starts from that same evidence, models the preferred's rights through a backsolve, and concludes the fair market value of one share of common stock. Whether you call it 409A vs venture valuation or 409A vs investor valuation, comparing the two without accounting for those rights is comparing two different securities.

For founders and CFOs, the practical habits are straightforward. Read the term sheet's preference terms, not just the headline, when forecasting the next 409A. Pause grants once a priced round becomes likely, and refresh the 409A as of closing. And never price options from the post-money valuation divided by the share count; that is the investors' number, not the fair market value of your common stock.

Whether a valuation qualifies for a presumption of reasonableness under Treasury Regulations Section 1.409A-1(b)(5)(iv)(B), and how a specific grant is taxed, depends on the facts; consult your own counsel and tax advisor.
