Follow-On Public Offer (FPO): How It Differs From an IPO and What Investors Should Check

A follow-on public offer is what happens when a company that is already listed comes back to the market for more money. It sold shares once, in its IPO. Now it wants to sell more, to the public, through a formal offer document. In India you will usually see it called an FPO or a “further public offer”, and while it borrows most of the plumbing of an IPO, the questions an investor should ask are quite different.

With an IPO you are trying to value a business you have never been able to buy. With an FPO the stock already trades. You can see its price every second. So the real question is simpler and sharper: why does a listed company need fresh money, and is the price it is asking a fair deal compared with what the market already charges?

What a follow-on public offer actually is

Investopedia defines an FPO as the issuance of shares by a public company after its initial public offering. Companies typically use the money to fund growth or to reduce debt. It splits FPOs into two kinds:

• Dilutive. The company creates new shares and sells them. The money goes to the company, the share count goes up, and each existing share now owns a smaller slice of the business.
• Non-dilutive. Existing holders, often founders, directors or pre-IPO investors, sell shares they already own. No new shares are created, so earnings per share does not change, and the cash goes to the sellers rather than the company.

That split matters more than the label. Two offers can both be called FPOs and mean completely different things for you as a shareholder. One is the company raising capital. The other is somebody leaving, or trimming.

How it differs from an IPO

An IPO is a private company selling shares to the public for the first time. There is no traded price, so price discovery happens entirely inside the book. In an FPO, the book is built in the shadow of a live market price. If the offer price is too close to where the stock trades, nobody bothers to apply; they can just buy on the exchange. That is why FPOs are almost always priced at a discount to the market.

The other big difference is information. A listed company has years of quarterly results, shareholding patterns and annual reports in the public domain. You are not guessing from a draft prospectus alone. Our guide to IPO investing in India covers the first-time issue side; this piece is about the second act.

How it differs from a rights issue

A rights offering lets existing shareholders buy additional shares at a discount, in proportion to what they already hold. The rights are often tradeable. An FPO is open to the public, existing holders or not. So in a rights issue you get first claim and can protect your percentage stake by subscribing. In an FPO, if you don’t bid, or don’t get allotted, your stake simply shrinks.

A real Indian example: the Vodafone Idea FPO

The cleanest recent case to learn from is Vodafone Idea’s offer in April 2024. In its filing to NSE and BSE dated 12 April 2024, the company described a further public offer of equity shares aggregating up to ₹18,000 crore, made under Chapter IV of the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018. The same filing set a floor price of ₹10 and a cap of ₹11 per share, with a minimum bid of 1,298 shares.

Look at how the company itself framed the price. The attached media release said the top of the band, ₹11, was at a discount of about 15% to the last closing price of ₹12.95, and about 26% below a recently approved preferential issue price to the promoter entity of ₹14.87. That is the FPO logic in one line: give investors a visible reason to come through the offer rather than buy on screen.

How did it go? According to BusinessLine’s report on the closing day, which it called the largest follow-on offering to date:

• The company had raised ₹5,400 crore from anchor investors before the issue opened.
• The issue was subscribed 6.99 times overall, with bids for 8,011 crore shares against 1,145.45 crore shares on offer.
• The qualified institutional buyer portion was subscribed 19.3 times, the non-institutional portion 4.5 times, and the retail portion one time.
• It received 11,59,356 applications in all.
• It was a fresh issue of 1,636.36 crore shares, which means it was dilutive.

That 1,636.36 crore figure checks out with simple division. ₹18,000 crore at ₹11 a share is about 1,636.36 crore shares. The same report said promoter equity (Vodafone Plc and the Aditya Birla Group) would fall to 37.3-38.2% from 50%, and the government’s stake would be cut to 24% from 33% once the shares were issued.

In an FPO you are not guessing the price of an unknown company. The market has already priced it. Your job is to work out whether the discount pays you for the dilution.

Notice what the subscription split tells you. Institutions piled in at nearly 20 times. Retail came in at roughly one time. The large headline number was driven by big money, and a small investor reading “subscribed seven times” might assume broad retail enthusiasm that wasn’t really there.

Worked example: what dilution does to your share of earnings

Let us take a hypothetical Company A. These numbers are made up purely to show the arithmetic.

• Shares outstanding: 100 crore
• Annual net profit: ₹500 crore
• Earnings per share: ₹500 crore ÷ 100 crore = ₹5
• Market price: ₹100

Company A announces a dilutive FPO of 25 crore new shares at ₹80 each. That raises ₹2,000 crore. The offer price is 20% below the ₹100 market price.

Step 1: the immediate hit

Share count goes to 125 crore. If profit stays at ₹500 crore, EPS drops to ₹500 crore ÷ 125 crore = ₹4. That is a 20% fall in EPS on day one, before the money has done anything.

Your ownership shrinks too. Say you held 1 crore shares before. That was 1% of the company. Afterwards it is 1 ÷ 125, or 0.8%, unless you bought into the offer.

Step 2: what the money earns

Now suppose the company uses the entire ₹2,000 crore to repay loans that cost it 9% a year. That saves ₹180 crore of interest before tax. At an assumed 25% tax rate, the post-tax saving is ₹135 crore.

New profit: ₹500 crore + ₹135 crore = ₹635 crore. New EPS: ₹635 crore ÷ 125 crore = ₹5.08.

So EPS ends up slightly higher than the original ₹5, even after 25% more shares. The FPO “paid for itself” in earnings terms. Change one assumption, though, and the picture flips. If the money sat idle or went into a project that takes three years to earn anything, shareholders would be stuck at ₹4 of EPS for a long time. Same FPO, very different outcome. That is why the use of proceeds is the single most important page in the offer document.

Step 3: the discount, from your side

If you apply at ₹80 while the stock trades at ₹100, the 20% gap looks like free money. It isn’t, quite. The market price tends to adjust once the extra supply of shares is known, and Investopedia notes that shares often fall when secondary offerings are announced, because they dilute holders and are often priced below market. By listing day the gap may have narrowed a lot. Treat the discount as compensation for dilution and timing risk, not as a guaranteed gain.

What to check before you bid in an FPO

Most of this is in the red herring prospectus. If you haven’t read one before, our walk-through of what to read in a red herring prospectus is a good starting point.

1. Fresh issue or offer for sale? Find out how much of the offer is new shares and how much is existing holders selling. New money into the company and money out to sellers are not the same story.
2. Use of proceeds. Debt repayment, capex, working capital, general corporate purposes. Vague buckets deserve suspicion. Specific, costed plans deserve credit.
3. The discount to market. Work it out yourself from the price band and the last close. A thin discount gives you little reason to apply instead of buying on the exchange.
4. Who is selling, and who is buying. Check whether promoters are subscribing or reducing their stake, and look at the anchor list. In the Vodafone Idea case, promoter holding was set to fall from 50%.
5. Post-issue share count. Calculate the new EPS on current profit, as we did above. Then ask how long it takes for the money to lift profit enough to undo the dilution.
6. The category split in subscription. Don’t read only the headline number. Look at retail, NII and QIB separately.
7. Follow-up after listing. Where proceeds are monitored, the monitoring agency report tells you whether the money went where the company said it would.

A seven-times subscription headline can hide a retail book that was barely full. Always split the number by investor category.

When an FPO is a good sign, and when it isn’t

There’s no blanket rule. A company raising equity to clean up an expensive balance sheet can come out stronger; Company A in our example did. A company raising money because operating cash flow can’t cover its commitments is a different animal, even if the offer is well subscribed. And a large non-dilutive sale by insiders tells you something about how they view the current price.

We’d suggest reading every FPO as three separate questions. Is the business worth owning at the market price? Is the discount enough to justify the dilution? And will the fresh money earn more than it costs existing shareholders? If you can answer all three with numbers rather than hope, you are ahead of most applicants.
