IPO vs FPO

An IPO takes a private company public for the first time; an FPO is an already-listed company raising more capital. How the two differ in pricing, risk, allotment and what each tells you about the company issuing it.

Both terms describe a company selling shares through the primary market, and both go through the same exchange machinery — a price band, a bidding window, category-wise allotment. The difference that actually matters sits upstream of all of that: an IPO has no market price to anchor to, and an FPO does. That one fact changes how each is priced, how much genuine uncertainty an applicant is taking on, and what the issue can tell you about the company behind it.

What each one is

An IPO — Initial Public Offering — is a private company selling shares to the public for the first time. Before it, there is no listed stock, no daily closing price, no analyst coverage. Everything the market knows about the company comes from the RHP itself.

An FPO — Follow-on Public Offering — is an already-listed company selling more shares through the exchanges, after its IPO. It comes in two shapes: a dilutive FPO, where the company issues new shares and the share count grows, and a non-dilutive FPO, where existing large shareholders sell shares they already hold — mechanically closer to the offer-for-sale split within an IPO than to a fresh issue.

How each is priced

This is the real difference. An IPO's price band is set by book building: the company and its bankers propose a range, weigh it against the P/E ratio of named listed peers, and let institutional demand during the anchor and QIB books confirm or push against it. There is no existing market price to check that band against — the band is the market's first real look at what the company might be worth.

An FPO starts from a number that already exists: the stock's closing price on the exchange in the days before the issue opens. SEBI's rules require the floor price to be set with reference to that recent trading price, and issuers commonly price the floor at a discount to it — sometimes with an additional flat discount for retail applicants on top. The market has already told you, every day, roughly what it thinks the shares are worth; the FPO is asking you to buy more of that at a discount, not to price something for the first time.

What actually differs in risk

The uncertainty an IPO applicant takes on is real and specific: no trading history, no market-tested price, and often a business whose financials are only now being disclosed publicly for the first time. An FPO removes exactly that uncertainty — the company has quarters or years of public filings, analyst estimates, and a price the market sets every trading day.

What an FPO does not remove is ordinary equity risk. A company can be badly run, overleveraged or overvalued whether it is doing its first offering or its fifth. The absence of IPO-specific uncertainty is not the same as the absence of risk — it just means the risk you're taking on is the same kind of risk as buying the stock on any other trading day, priced at a discount to encourage you to do it through the issue instead.

Why companies do FPOs

• Raising fresh capital without taking on debt — same motive as a fresh issue in an IPO, but from a company the market can already value.
• Meeting minimum public shareholding — SEBI requires listed companies to keep at least 25% of shares with the public; an FPO (or an OFS) is one way a company with promoter holding above that line brings it down.
• Large shareholders exiting in size — a non-dilutive FPO lets a big holder (often a promoter or a PE investor) sell a large block through the exchange mechanism rather than in the open market, where a sale that size would move the price sharply on its own.

Allotment mechanics are the same

Once the price is set, an FPO runs through the same category structure as an IPO — QIB, non-institutional and retail portions, with retail applications above the subscription level allotted by lottery on single lots, exactly as described in how IPO allotment works. Nothing about receiving shares, checking status with the registrar, or the T+3 listing timeline changes between the two. The entire difference between an IPO and an FPO lives in how the price got set, not in how the shares get handed out once it has.

Reading an FPO like you'd read an IPO

The questions worth asking are the same ones that matter for an IPO, just answered from a different starting point: how big is the discount to the current market price, is the issue dilutive or non-dilutive (check the fresh issue vs OFS split the same way you would for an IPO), and what does the company's recent quarterly performance — now public, unlike an IPO applicant's first look — actually show. An FPO gives you more evidence to work with than an IPO ever can on day one; the discount is the market's way of paying you for showing up anyway.
