How Is an IPO Priced?

An IPO price is not calculated. It is negotiated once, on a single evening, between the company's board and its lead underwriters, using the demand they collected from investors over the preceding two weeks.

Valuation work sets the starting range. The roadshow tests it. The final number is chosen after the market closes the night before trading begins, and it appears the next morning on the cover of the final prospectus.

Who sets the IPO price?

The company and its lead underwriters, jointly. Neither can set it alone.

The company's board typically delegates the decision to a pricing committee — a small subset of directors authorised to approve a price within a range the full board has already blessed. The lead underwriters bring the demand information; the committee decides whether to take it.

Nobody else has a vote. Not the SEC, which reviews disclosure and never passes on the price or the merits of the offering. Not the exchange. Not the investors in the book, who state what they would pay but cannot compel the outcome.

See The SEC does not approve IPOs · IPO underwriters.

Where does the initial price range come from?

From valuation work done before the deal is public, then tested against real investors.

Underwriters build a view from comparable public companies — trading multiples of revenue, earnings, or whatever metric the sector uses — adjusted for growth, margin and scale. Discounted cash flow appears in the analysis and rarely drives it. For a company with no profits and a short operating history, comparables do most of the work.

Two inputs sharpen the range before it is printed. Testing-the-waters meetings let an emerging growth company speak to qualified institutional buyers before filing publicly, and the feedback from those meetings shapes what range the bankers are willing to defend. Separately, the range itself must be a bona fide estimate, not a placeholder — it is filed in an amended registration statement and printed on the cover of the red herring that goes out with the roadshow.

See Testing the waters · Red herring prospectus · IPO valuation.

How does the roadshow turn a range into a price?

Through bookbuilding. Investors tell the underwriters how many shares they want and at what price; the underwriters assemble those responses into a picture of demand at each level.

That picture is a demand curve, not a queue. It tells the bankers roughly how much interest exists at $20, at $22, at $24 — which is what makes a price defensible rather than guessed.

See IPO bookbuilding.

Can the price range change before pricing?

Yes, and a changed range is one of the clearest public signals a deal produces.

If demand is strong, the company files an amended registration statement raising the range, increasing the number of shares, or both. If demand is weak, it cuts the range, cuts the size, or postpones. Each revision is a public filing, which is why a range change is visible to anyone watching the filing feed rather than only to the investors in the book.

The final price can also land outside the last published range entirely — above it when demand overwhelms the range, below it when the deal is struggling and the company would rather price low than pull the offering.

See The IPO filing lifecycle · Withdrawn and postponed IPOs.

What happens on pricing night?

The sequence is compressed into a few hours after the market closes.

The underwriters close the book and present final demand to the company.
The pricing committee approves a price and a deal size.
The company and the underwriters sign the underwriting agreement — the point at which the underwriters commit to buy the shares. Until that signature, in a firm-commitment offering, nobody is legally obliged to do the deal.
The auditors deliver a comfort letter; counsel deliver their opinions.
Allocations go out to investors overnight.
The final prospectus, on Form 424B4, is filed the following morning with the price on the cover.
Trading opens, at a price the exchange's opening auction produces independently.

See What is Form 424B4? · IPO allocation · IPO opening auction.

Why is the price usually set below where the market clears?

Because underwriters price to leave the deal covered, not to extract the last dollar.

A deal priced exactly at the level where demand exhausts supply has no margin for error: any investor who drops out leaves shares unsold. Pricing somewhat below that level keeps the book several times oversubscribed, gives the underwriters confidence the deal will place, and gives allocated investors a reason to take shares in future offerings from the same bank.

Whether that margin is prudent underwriting or a transfer of value from the issuer to the bank's clients is the central argument in the underpricing literature, and the evidence supports parts of both readings.

Are there other ways to price an IPO?

Three alternatives exist, and their rarity is itself informative.

Fixed price. The price is set in advance and investors subscribe at it, with no bookbuilding. Common historically and still used in some markets, particularly for smaller offerings and retail tranches. It removes price discovery entirely, which is why underpricing in fixed-price markets has historically been much larger.

Dutch auction. Investors submit price and quantity bids and a single clearing price is set from the demand curve. Google used a modified version in 2004. It reduces the pop that allocated investors value, which makes books harder to build, and underwriters have little reason to promote it. It has never become standard in the US.

Direct listing. No offer price at all. The exchange publishes a reference price and the opening auction determines where trading starts. This eliminates offer-to-open underpricing by construction, but it is practical mainly for companies well known enough not to need the marketing an underwritten deal provides.

See Dutch auction IPO · IPO vs. direct listing.

Does the company receive the full offer price?

No. The underwriters keep a gross spread — a percentage of the offer price, disclosed on the prospectus cover as the difference between the price to the public and the proceeds to the company.

The 7% figure that circulates as "the" US underwriting fee is a documented historical regularity, most consistently observed in smaller and mid-sized offerings, rather than a current universal rate. Large offerings frequently price well below it.

The company also pays its own legal, accounting, printing, exchange and filing costs, which are disclosed separately and are not part of the spread.

See How much does an IPO cost? · IPO underwriting fees.

Where is the final price disclosed?

On the cover of the final prospectus, filed on Form 424B4, generally within two business days of pricing.

That filing is the authoritative record: the price to the public, the underwriting discount per share, the proceeds to the company before expenses, the proceeds to any selling shareholders, and the size of the over-allotment option. Everything we publish about a deal's pricing comes from it.

See S-1 vs. 424B4 · Methodology.

Does the offer price reflect what the company is worth?

It reflects what a particular group of investors was willing to pay for a particular slice of it on a particular evening. That is narrower than a valuation, for three reasons.

The float is small. Most IPOs sell a modest fraction of shares outstanding. Pricing a 12% slice is not the same exercise as pricing the whole business.

Timing dominates. The same company can price materially differently in March and in September, for reasons unrelated to its operations.

Underpricing is deliberate. Everyone in the room expects the price to sit below where the stock will trade. That is the design rather than a failure of it.

The implied market capitalisation quoted in coverage is the offer price multiplied by shares outstanding — a useful reference number and a poor estimate of intrinsic value.

See Public float · IPO valuation.

Quick answers

Is the IPO price the same as the opening price? No. The offer price is negotiated; the opening price is produced by an exchange auction the next morning. See Offer price vs. opening price.

Does the SEC approve the price? No. The SEC reviews disclosure and never passes on the merits or the price of an offering.

Can the price be set above the range? Yes, when demand supports it.

When exactly is it set? After the market closes, the evening before trading begins.

Who gets shares at that price? Only investors the underwriters allocate to. See IPO allocation.
