Primary Markets & Public Issue Process: Filing to Listing Interview Guide

Primary Markets & Public Issue Process: Filing to Listing Interview Guide

Why would a company spend months revealing its financials, risks, promoters, bankers, lawsuits and strategy to the public just to sell shares for a few days? Because a public issue is not just fundraising - it is a credibility test, a regulatory test and a market-demand test happening at the same time.

  • Primary market is where securities are issued to investors for the first time; secondary market is where listed securities trade between investors.
  • A public issue can be an IPO by an unlisted company or an FPO by an already listed company.
  • The Indian IPO journey typically moves from DRHP filing to SEBI observations, RHP, bidding, allotment, refunds/share credit and listing.
  • Fresh issue gives money to the company; offer for sale gives money to selling shareholders.
  • Key participants are the issuer, merchant bankers, SEBI, stock exchanges, registrar, depositories, banks, underwriters and investors.
  • Since December 2023, Indian mainboard IPOs follow a T+3 listing timeline from issue closure, making execution discipline critical.
  • The biggest interview trap: saying every IPO raises capital for the company. In an OFS, the company receives no issue proceeds.

Big Picture: A Public Issue Is a Regulated Bridge from Private Capital to Public Ownership

A company enters the primary market when it wants public investors to buy securities directly from the issuer or selling shareholders. The listing that follows is a separate event: it gives those securities a tradable life in the secondary market.

Core Explanation: The Public Issue Process from Filing to Listing

The public issue process exists to solve one central problem: public investors are buying into a business they do not control and may not know deeply. Regulation therefore forces the company to disclose material information, appoint accountable intermediaries and follow a transparent allotment and listing process.

1. Choose the route: IPO, FPO, fresh issue or offer for sale

An IPO is the first public issue by an unlisted company. An FPO is a further public offer by a company that is already listed. Within either, the issue may be a fresh issue, an offer for sale or a mix of both.

2. Appoint intermediaries and prepare the DRHP

The company appoints merchant bankers, legal counsel, auditors, registrar, bankers and other intermediaries. The key document is the Draft Red Herring Prospectus, or DRHP. It contains the business description, risk factors, financial statements, industry overview, promoter details, litigation, use of proceeds and issue structure.

3. File with SEBI and receive observations

For Indian public issues, the draft offer document is filed with SEBI under the applicable ICDR framework. SEBI does not certify business quality or guarantee returns. Its review is mainly about disclosure adequacy, regulatory compliance and investor protection.

4. File the RHP and open bidding

After observations are addressed, the company files the Red Herring Prospectus, or RHP. In a book-built issue, the price band is announced and investors bid within that range. Categories usually include QIBs, NIIs and retail investors, subject to applicable rules.

5. Determine allotment, process refunds and credit shares

Once bidding closes, the final issue price is determined, allotment is made as per category rules and oversubscription logic, unsuccessful applicants receive refunds or blocked amounts are released, and successful applicants receive shares in their demat accounts.

6. List on the exchange

Listing is when the security begins trading on NSE, BSE or another approved exchange. In India, mainboard IPOs follow a T+3 listing timeline from issue closure, which means the allotment, credit and trading-start process is compressed and operationally demanding.

Public issue quality matrix A two by two matrix comparing use of proceeds and demand quality in an IPO. Use of proceeds: exit-heavy to fresh growth capital Demand quality OFS + broad demand Not fatal if business quality is strong Fresh + broad demand Best zone growth capital meets trust OFS + weak demand Red flag exit without market conviction Fresh + weak demand Execution risk good plan, poor appetite
Do not judge an IPO only by subscription; connect investor demand with whether the issue funds growth or enables exit.

The Players in a Public Issue and What Each One Does

A strong answer names the ecosystem, not just the issuing company. Public issues are deliberately multi-party because each participant reduces a different risk for investors.

How to Read Any IPO Quickly: Six Practical Measures

Use these measures to move from description to judgement. In interviews, say clearly that no single metric proves issue quality; the pattern matters.

Definitions You Must Be Able to Say Cleanly

  • Primary market: The market where securities are issued to investors for the first time.
  • Public issue: An offer of securities made to the public under securities-law disclosure and allotment rules.
  • IPO: The first public issue of shares by a company that was previously unlisted.
  • FPO: A further public issue of shares by a company that is already listed.
  • DRHP: The draft offer document filed before approval, excluding final price and issue size details.
  • RHP: The offer document used for bidding, with key issue terms but not the final issue price.
  • Listing: Admission of securities to trading on a recognised stock exchange.

Case Study: Mankind Pharma and the IPO That Proved OFS Is Not Automatically Weak

Mankind Pharma listed in India in 2023 through an IPO structured as an offer for sale, showing that a non-fresh-capital issue can still attract serious investor interest when the business story is credible.

Mankind Pharma made investors evaluate an operating franchise, not just whether IPO money entered the company.
Mankind Pharma made investors evaluate an operating franchise, not just whether IPO money entered the company.

Situation: Mankind Pharma was already a well-known Indian pharmaceutical and consumer-healthcare company before listing. Its IPO was structured as an offer for sale, meaning existing shareholders sold shares and the company itself did not receive fresh proceeds from the issue.

The move: The company and its bankers had to make the market comfortable with a simple but important argument: even without fresh capital, public investors were getting access to a large domestic-focused healthcare franchise. The primary driver was business credibility - a recognised domestic brand portfolio and operating scale. Supporting drivers included a regulated disclosure process, institutional investor evaluation, professional issue management and a market context that rewarded profitable, understandable businesses.

Outcome and lesson: The IPO was completed and Mankind Pharma listed on Indian exchanges in May 2023. The strategic lesson is not that every OFS is good. The lesson is sharper: OFS is a structure, not a verdict. If the business is strong, the seller rationale is explainable and institutional demand is healthy, an OFS can still be a credible public issue.

How AI Changes Primary Markets & the Public Issue Process

AI is changing the IPO workflow less through glamour and more through speed, consistency and risk detection.

  • Faster DRHP and RHP analysis: Investors can use LLMs to summarise risk factors, related-party transactions, litigation and use of proceeds across hundreds of pages. The edge is not replacing judgement - it is finding the right pages faster.
  • Better diligence by intermediaries: Merchant bankers and legal teams increasingly use AI-assisted document review to identify inconsistencies between financial statements, risk disclosures, contracts and regulatory filings. Human sign-off remains essential because offer documents carry legal responsibility.
  • Demand sensing and investor targeting: Banks can analyse investor behaviour, sector appetite, macro conditions and comparable listings to plan roadshows and book-building strategy more intelligently. The final pricing decision still needs market judgement and regulatory compliance.

Load the DRHP or RHP of a recent IPO into NotebookLM and ask: "Summarise the issue structure, fresh issue versus OFS split, top five risk factors, stated use of proceeds and likely interview questions." Then verify every important claim against the original document.

Interview Relevance

"Walk me through the IPO process in India from DRHP filing to listing. Also explain the difference between a fresh issue and an offer for sale."

If you want to sound polished, say: "SEBI review should not be described as an investment recommendation. It is a disclosure and compliance process, not a guarantee of returns."

The mistake: saying "an IPO raises money for the company" as if it is always true. Why it costs candidates: it shows you cannot distinguish fresh issue from offer for sale. One-line fix: always ask, "Is the issue fresh, OFS or mixed, and who receives the proceeds?"

What to Revise Next

Now that you understand the filing-to-listing journey, revise the two areas that sit immediately around it: how the issue price is discovered before listing, and how the stock trades after listing.
