IPO vs OFS
Whether new money goes into the company, or existing owners simply cash out
Imagine a bakery opening its ownership to outside investors two different ways. In the first, it bakes and sells brand new shares of the business, and every rupee raised goes straight into buying new ovens and opening more branches. In the second, the founder simply sells some of the shares they already personally own, and every rupee goes straight into the founder's own pocket, with the bakery itself receiving nothing. That is the entire difference between an IPO's fresh issue component and an Offer for Sale.
An Initial Public Offering can include a fresh issue, newly created shares sold for the first time, with the proceeds flowing directly onto the company's own balance sheet to fund growth, repay debt or strengthen its finances. It can also include an Offer for Sale, where existing shareholders, often promoters or early investors like private equity and venture capital funds, sell some of their already-held shares to the public, with the proceeds going entirely to those selling shareholders, not the company.
Most Indian IPOs actually combine both components in a single offering, and reading the specific split between fresh issue and OFS in the prospectus tells you a great deal about the company's real motivation for going public. A large fresh issue signals genuine capital-raising need. A large OFS signals existing investors, especially private equity or venture backers who have held the stock for years, are primarily using the listing as their exit route.
This distinction matters directly to a prospective investor, because a company raising fresh capital is, at least on paper, using the listing to grow, while a company that is mostly OFS is essentially providing liquidity to its existing owners, with the newly public company's own cash position unaffected either way.
Whenever a mega IPO is criticised in financial media as being "just an exit for investors" rather than a genuine growth capital raise, that criticism is almost always pointing directly at a prospectus where the OFS component significantly outweighs the fresh issue, a completely legal and common structure, but one worth understanding before assuming every large IPO number represents money flowing into the company itself.
