Introduction: Three Ways to Access Public Capital
When a company needs to raise funds from the public or when investors want to sell their stakes, they can use three primary mechanisms: an Initial Public Offering (IPO), a Follow-on Public Offer (FPO), or an Offer for Sale (OFS). While all three result in shares being sold to investors, they differ fundamentally in purpose, structure, who receives the money, and impact on the company.
Initial Public Offering (IPO)
An IPO is the first time a private company sells its shares to the general public and gets listed on a stock exchange (BSE, NSE, or both in India). It is the company's debut on the public market.
Key characteristics:
- Company transitions from private to publicly listed status
- Can include both fresh issue (money goes to company) and OFS (money goes to sellers)
- Requires filing a DRHP with SEBI and receiving observations
- Typically subject to a 3-year profitability track record requirement (with some exemptions for high-growth companies)
- Minimum IPO size is ₹10 crore on mainboard; ₹1 crore on SME platform
Who benefits most: The company (if fresh issue), early investors and promoters (if OFS component), and the investing public who can now trade the shares freely.
Investor angle: IPOs offer the chance to invest in a company's growth story early. However, lack of price history and limited comparable data makes analysis harder than for listed stocks.
Follow-on Public Offer (FPO)
An FPO is a public offering made by a company that is already listed on the stock exchange. The company issues new shares to raise additional capital from the public.
Key characteristics:
- Only available to already-listed companies
- Can be done at a discount to the prevailing market price to attract investors
- Leads to equity dilution — existing shareholders own a smaller percentage of the company
- Common when companies need capital for large expansion projects, acquisitions, or balance sheet strengthening
- Less common in India's recent market compared to IPOs; examples include Yes Bank FPO (2020), NTPC FPO (2010)
Who benefits: The company gets fresh capital. Existing shareholders may see dilution in the short term but benefit if the capital is deployed effectively.
Investor angle: FPOs are generally easier to evaluate than IPOs because the company has a listed price history. However, if the FPO is priced at market value or a premium (uncommon), it offers no price advantage. FPOs priced at a discount are particularly attractive.
Offer for Sale (OFS)
An OFS is a mechanism where existing shareholders (typically promoters or large institutional investors) sell a portion of their existing shareholding through the stock exchange platform to the public. The company does not receive any proceeds — all money goes to the selling shareholders.
Key characteristics:
- Available only to listed companies (through exchange OFS mechanism) or as part of an IPO
- No fresh shares are created — only existing shares change hands
- Faster and cheaper to execute than an FPO — no SEBI prospectus requirement for listed company OFS
- Typically completed in 1–2 days
- Often used by government to divest stakes in PSUs (ONGC, Coal India, LIC OFS)
- Retail investors get a 5% discount on OFS price typically
Who benefits: The selling shareholders — promoters, PE funds, or the government — who want to reduce their stake. The company gets nothing directly.
Investor angle: An OFS by promoters should be viewed with some caution — why are insiders selling? However, OFS by PE/VC funds exiting after a multi-year holding is normal and not negative for the company. Government OFS (divestment) is often at attractive pricing.
Side-by-Side Comparison
| Feature | IPO | FPO | OFS |
|---|---|---|---|
| Company status | Unlisted | Listed | Can be either |
| New shares issued? | Yes (usually) | Yes | No |
| Money goes to | Company + sellers | Company | Sellers only |
| Equity dilution | Yes (if fresh issue) | Yes | No |
| SEBI filing | DRHP required | Prospectus required | Not required (listed) |
| Timeline | 3–6 months | 2–4 months | 1–2 days |
Real-World Examples in India
- IPO: Zomato (2021), LIC (2022), Hyundai India (2024) — first-time public listings
- FPO: Yes Bank (2020) — raised ₹15,000 crore to shore up capital after balance sheet crisis
- OFS: Paytm promoter OFS (2024), multiple government divestments in ONGC, NTPC, BHEL
Which Is Best for Investors?
There is no universal answer. Each has a context:
- An IPO offers access to growth stories before they are fully priced into the market.
- An FPO at a discount to market price can offer immediate value.
- A government OFS often comes at a discount and is low-risk for stable PSU stocks.
What matters most is not the mechanism but the quality of the underlying business, the valuation, and the purpose of the offering.
