Fixed Price Issue: How It Differs From Book Building and What It Means for Your IPO Application

Most IPO ads we see today print a price band, something like ₹480 to ₹505, and leave the final number for later. A fixed price issue skips that step. The company and its merchant banker pick one price before the offer opens, write it into the offer document, and everyone applies at that price. No bidding, no cut-off, no guessing where the final number will land.

That sounds simpler, and in some ways it is. But the choice between a fixed price issue and a book-built issue changes more than the price line. It changes who gets how many shares, what document you read, and how much you can learn about demand before you commit money. This guide goes through all of it with a worked example, using SEBI’s own documents as the base.

If you are new to public offers, our IPO investing in India guide covers the wider process, and this piece slots in right after it.

What a fixed price issue actually is

SEBI’s investor FAQ on issues by Indian companies puts it in one line: when the issuer decides the issue price at the outset and mentions it in the offer document, it is commonly called a fixed price issue. A book-built issue is the other kind, where the price is discovered from the demand received from investors at various price levels.

The same FAQ makes a point about pricing that people often miss. SEBI does not set IPO prices. Since 1992 Indian issuers have priced their own shares, in consultation with the merchant banker, and the offer document has to disclose the parameters behind the price, such as EPS, the P/E multiple, return on net worth and comparisons with listed peers. That is true whether the price is fixed or book-built. So a fixed price is not a “regulated” price. It is the company’s call, made earlier.

Under the SEBI ICDR Regulations, 2018 (the rulebook for public issues), an issuer can go either way. SEBI’s General Information Document for investing in public offers says exactly that: the offer price is set either through the book building process or through a fixed price offer, and investors should check the offer document or the offer advertisements to see which one they are dealing with.

Fixed price issue vs book building: the core differences

Here is the side-by-side, built only from SEBI’s documents and the regulation text.

The 120% band rule and the cut-off rules come from SEBI’s general information document. The offer document points come from SEBI’s investor FAQ, which explains that a red herring prospectus carries all relevant details except the price or number of shares, while a full prospectus has them all and is registered with the Registrar of Companies before the issue opens for a fixed price issue, and only after the issue closes for a book-built one. The allocation numbers are from Regulation 32 of the ICDR Regulations, which we go through next. If you want a refresher on the offer document itself, see our explainer on the red herring prospectus.

A fixed price is not a regulated price. It is the company’s own call on value, made before a single investor has shown their hand.

Who gets the shares: allocation in a fixed price issue

This is where the two routes really part ways. Regulation 32 of the ICDR Regulations sets the split of the net offer (the shares on offer to the public after any reservations, such as for employees).

For an issue made other than through book building, which is the fixed price route, Regulation 32(4) says:

• a minimum of 50% goes to retail individual investors, and
• the rest goes to individual applicants who are not retail investors, and to other investors including corporate bodies and institutions, irrespective of the number of shares they applied for.

Any unsubscribed portion in one category can be allocated to applicants in the other. And the regulation adds an explanation: if retail investors are entitled to more than 50% of the issue size on a proportionate basis, they get that higher percentage.

Compare that with the book-built route. Under Regulation 32(1), the regular case, the net offer is split not less than 35% to retail, not less than 15% to non-institutional investors and not more than 50% to qualified institutional buyers (QIBs), with 5% of the QIB portion set aside for mutual funds. Under Regulation 32(2), for issuers that come in under Regulation 6(2), QIBs must get not less than 75%, non-institutional investors not more than 15% and retail not more than 10%.

So on paper, the fixed price route is the most retail-heavy structure in the rulebook. At least half the net offer is reserved for small investors, against at least 35% in a regular book-built IPO. There is also no separate QIB bucket in the fixed price split. Institutions sit in the “other investors” group together with corporates and bigger individual applicants.

A worked example: one company, two routes

Let’s make this concrete with a hypothetical company. Call it Company K. None of these numbers describe a real issue; they are only there to show the mechanics.

Route 1: Company K goes fixed price

Company K offers 20,00,000 shares to the public (the net offer) at a fixed price of ₹50. That is an issue of ₹10 crore.

• Retail reservation: at least 50% of 20,00,000, so 10,00,000 shares.
• Everyone else: the remaining 10,00,000 shares.

Applications come in like this: retail investors apply for 30,00,000 shares, and the other group applies for only 5,00,000.

The other group is undersubscribed by 5,00,000 shares. Regulation 32(4) allows that unsubscribed portion to go to the other category, so if it is moved across, retail ends up with 15,00,000 shares against applications for 30,00,000. Retail is then 2 times subscribed on the shares available to it. The other group gets all 5,00,000 shares it asked for.

Notice what the retail investor knew going in. The price was ₹50 from day one. Their application amount was simply shares applied for multiplied by ₹50. Nothing about the final price depended on anyone else’s bids.

Route 2: Company K goes the book-built way

Now suppose Company K instead announces a price band of ₹50 to ₹58. Is that legal? The cap has to be less than or equal to 120% of the floor. Here ₹58 is 116% of ₹50, so yes.

Investors bid at different prices inside the band. The final price is then found from the demand curve. SEBI’s general information document shows how with its own illustration: an issuer wants to sell 3,000 shares and receives these bids.

Reading down from the highest price, cumulative demand first covers the full 3,000 shares at ₹22. The document explains that the highest price at which the issuer can sell the desired number of shares is where the book cuts off, ₹22 in this case, and that the issuer can finalise the offer price at or below that cut-off. All bids at or above the offer price, and all cut-off bids, are valid.

Back to Company K. A retail investor bidding in its book-built version has two choices: pick a price within ₹50 to ₹58, or tick the cut-off box and agree to pay whatever final price is set. The general information document says that for retail investors bidding at cut-off, the amount blocked is based on the cap price. So the investor has to have ₹58 a share available, even if the final price lands lower and the difference is later released.

We walk through that process step by step in our explainer on the book building process.

What changes for you as an applicant

Putting the rules and the example together, here is what we would actually pay attention to.

1. You carry all the pricing judgement

In a book-built issue, the final price reflects bids from QIBs and other investors. That is not a guarantee of fair value, since the listing price is still set by the market. Still, the price has at least been tested against demand. In a fixed price issue, the price was set before anyone bid. So the valuation section of the prospectus, the EPS, P/E, return on net worth and peer comparison that SEBI requires, matters even more. Read it as if nobody else has checked it for you, because in a sense nobody has.

2. More room for retail, but more competition too

A minimum 50% retail share is a bigger slice than the 35% floor in a regular book-built IPO. That does not mean your odds are automatically better. If the issue is popular, a bigger retail bucket also attracts more retail applications. What it does mean is that, by design, small investors as a group are a larger part of the shareholder base on listing day.

3. No anchor book to read

Many investors look at the anchor allocation the day before a book-built IPO opens to see which institutions have committed. The anchor provision in Regulation 32(3) is written only for issues made through the book building process. With a fixed price issue, you will not have that signal, so you are back to the prospectus and your own reading of the business.

4. Simpler maths on the application

One price means one number to block. There is no question of whether to bid at the cap or at cut-off, and no chance of the final price moving against you inside a band. For someone applying through ASBA (the system where your bank blocks the amount instead of debiting it), that is genuinely easier to plan around.

In a book-built IPO the market has at least argued about the price. In a fixed price issue, the argument is one you have to have with the prospectus yourself.

How to tell which kind of issue you are looking at

SEBI’s general information document tells investors to check the offer document or the offer advertisements. In practice, three quick tells help:

• One number or two? A single price points to a fixed price issue. A price band, or a floor price with no cap, points to book building.
• Which document? A red herring prospectus before opening means book building, since the RHP leaves out the final price. A prospectus that already carries the price fits the fixed price route.
• Is there a cut-off option? The cut-off box on the form only exists in a book-built issue.

Once you know which route it is, the allocation table in the offer document will show you the exact split, including any employee or shareholder reservations that come out before the net offer.

Common misreadings

“Fixed price means SEBI approved the price.” No. As SEBI’s own FAQ says, SEBI plays no role in fixing the price. The issuer and the merchant banker decide it.

“Fixed price means the listing price is fixed too.” Not at all. The issue price is only the price you pay to get the shares. Once listed, the stock trades wherever buyers and sellers take it, just like a book-built IPO.

“The 50% retail share means half the applicants get shares.” The 50% refers to the share of the net offer reserved for retail individual investors, not the share of applicants who receive an allotment. If retail demand is many times the shares available, many applicants can get nothing.

“Book building is always better for investors.” It gives more information during the issue, but it also gives the issuer a chance to price at the top of whatever demand shows up. A fixed price can sometimes be set conservatively. Neither route tells you whether the stock is cheap; only the business and the valuation can.

The bottom line

A fixed price issue is the older, plainer way to run a public offer. One price, set at the outset, at least half the net offer reserved for retail investors, and no bidding inside a band. Book building adds price discovery, an anchor book and a cut-off option, at the cost of a little more complexity for the applicant.

Neither one is a shortcut to a good investment. With a fixed price issue, though, the burden of judging value sits more squarely on you. Read the basis for the issue price section, compare the P/E with listed peers, and decide whether you would buy the stock at that price if it were already trading. If the answer is no, the simplicity of the form is not a reason to apply.
