IPO meaning in simple words: when a company first sells shares

The Plainomics desk1 source

IPO: (initial public offering) is the first time a company sells its shares to the public, so that anyone can then buy and sell them on a stock exchange.

At night under a single bulb, Sameer paces in front of the closed stall while Riya sits on the red stool with her laptop.

The story

two people, one chai stall

October 2023. The night before Sameer Chai's IPO opens, Sameer can't sit still.

Sameer

From tomorrow, strangers can own a piece of my chai company. Why does that feel so odd?

Riya

Because it's an IPO, an initial public offering. It's the first time the public can buy our shares. The price is ₹40 each.

Sameer

And all the money comes to us?

Riya

Not all of it. We're selling 1.5 crore new shares. That's ₹60 crore for the company. That part is called the fresh issue.

Sameer

And the rest?

Riya

Our early investor is selling his 50 lakh shares too. That's ₹20 crore, and it goes to him, not to us. So the whole issue is ₹80 crore.

Sameer

Do I lose control?

Riya

No. You keep your 3 crore shares. After the IPO there are 5 crore shares, so you own 60% and the public owns 40%.

Sameer

And then?

Riya

A few days after bidding closes, the shares are listed. From then on, anyone can buy or sell them on the exchange, every trading day.

The grown-up version

same idea, exact words

An initial public offer is a company's first offer of shares to the public, after which the shares are listed on a stock exchange. It can combine a fresh issue, where new shares are issued and the money goes to the company, with an offer for sale, where existing shareholders sell and keep the proceeds. The issuer first files a draft offer document with SEBI and the stock exchanges, and must meet SEBI's eligibility tests, such as a track record of profits and net worth, or else allot at least 75% of the net offer to qualified institutional buyers. Promoters must hold at least 20% of the post-issue capital, which is locked in, usually for 18 months.

Formula

Issue size = Fresh issue + Offer for sale

Don't mix it up

the usual confusions

  • IPO ≠ DRHP

    The DRHP is the draft document filed with SEBI months before the IPO. The IPO is the sale itself.

  • IPO ≠ offer for sale

    An offer for sale is the part of an IPO where existing owners sell their shares. That money goes to them, not to the company.

  • IPO ≠ FPO (further public offer)

    An FPO is when a company that is already listed sells more shares to the public. An IPO is only the first time.

आईपीओ (IPO)

IPO वह मौक़ा है जब कोई कंपनी पहली बार अपने शेयर आम लोगों को बेचती है, ताकि बाद में कोई भी उन्हें स्टॉक एक्सचेंज पर ख़रीद-बेच सके।
