Unlisted to Listed — The IPO Journey
For most unlisted share investors, the IPO is the destination — the moment when a private company joins the public markets and your pre-IPO investment becomes a freely tradable listed share. But the journey from unlisted to listed is not an overnight event. It is a structured regulatory process that can take months, and sometimes years.
This chapter gives you a complete picture of how that journey works — from the company's internal decision to go public, all the way to the day of listing. Understanding this timeline helps you set realistic expectations and plan your investment horizon properly.
Why Do Companies Go Public?
Companies list on stock exchanges for several reasons, and understanding their motivation helps you assess how credible an IPO is for any unlisted company you hold:
To raise fresh capital for expansion, debt repayment, or acquisitions.
To provide an exit for early investors — VCs, PE funds, and founders who have held equity for years.
To increase brand visibility and credibility — listed companies are perceived as more established.
To use listed shares as currency for employee stock options and future acquisitions.
To enable price discovery for the company's shares in a regulated, transparent market.
Not all unlisted companies have IPO as their goal. Some companies — like NSE, which has faced regulatory hurdles for years — may intend to list but face delays. Others may opt for a strategic sale (acquisition) instead of an IPO. This is why an IPO should never be the only exit strategy you count on.
The Complete IPO Journey — Stage by Stage
Stage 1 | Board and Shareholder Approval The company's board of directors formally approves the decision to pursue an IPO. Existing shareholders (VCs, PE funds, promoters) also typically approve via a shareholders' resolution. This is an internal decision — often not publicly announced. |
Stage 2 | Appointment of Investment Bankers (Book Running Lead Managers) The company appoints SEBI-registered merchant bankers (also called BRLMs or lead managers) to manage the IPO. Examples include Kotak Investment Banking, Axis Capital, ICICI Securities, JM Financial. These bankers prepare all IPO documentation and manage the process. |
Stage 3 | Due Diligence and Documentation The investment bankers and legal teams conduct extensive due diligence. Financial statements are audited. Legal issues are resolved. The DRHP (Draft Red Herring Prospectus) is prepared — a comprehensive document disclosing everything about the company: business, financials, risk factors, shareholding, and IPO details. |
Stage 4 | DRHP Filed with SEBI The DRHP is filed with SEBI and simultaneously published on the SEBI website and the company's website. THIS IS THE SIGNAL. Once the DRHP is public, the unlisted market freezes for this company. The IPO process is officially underway. |
Stage 5 | SEBI Review Period SEBI reviews the DRHP and may issue queries or ask for additional disclosures. The company and its bankers respond. Once satisfied, SEBI issues an observation letter — effectively clearing the IPO to proceed. This typically takes 30 to 75 days. |
Stage 6 | Pre-IPO Placement (Optional) Some companies do a pre-IPO placement — selling shares to a small group of institutional investors at a price slightly below the IPO price. This reduces the fresh issue size and helps gauge institutional appetite. |
Stage 7 | RHP Filed and IPO Dates Announced The final Red Herring Prospectus (RHP) is filed, containing the price band for the IPO. IPO open and close dates are announced publicly. This is when newspaper and media coverage peaks. |
Stage 8 | IPO Subscription Period (3 Days) The IPO is open for public subscription — typically for 3 business days. Retail investors, QIBs, and HNIs apply for shares. |
Stage 9 | Allotment and Refunds Shares are allotted to successful applicants. Excess application amounts are refunded. Your pre-IPO lock-in period begins from this allotment date. |
Stage 10 | Listing Day The company's shares begin trading on NSE and/or BSE. Your unlisted shares are now officially listed. But remember — you cannot sell until the lock-in period expires. |
Typical Timeline from DRHP Filing to Listing
Stage | Approximate Duration |
DRHP preparation (before filing) | 3 to 6 months of internal work |
SEBI review after DRHP filing | 30 to 75 days |
SEBI observation letter to IPO opening | 2 to 4 weeks |
IPO subscription period | 3 business days |
Allotment to listing | 6 to 7 business days |
Total from DRHP filing to listing | Approximately 3 to 4 months |
Lock-in after listing (Mainboard) | 6 months from allotment date |
Lock-in after listing (SME) | 1 year from allotment date |
Real-World Context — Companies Your Audience Holds
Let us apply this framework to companies that are actively traded in the unlisted market:
Company | IPO Status Context |
NSE (National Stock Exchange) | Has been planning an IPO for years. SEBI has raised concerns about co-location issues and governance. IPO remains pending. Classic example of how regulatory issues can delay listing indefinitely. |
Zepto | Raised significant funding and has been in active IPO discussions. DRHP filing is closely watched. Once filed, the unlisted market for Zepto shares will freeze immediately. |
OYO (Oravel Stays) | Filed and withdrew its DRHP once. Refiled later with revised financials. Demonstrates that companies can restart the IPO process after delays. |
PharmEasy (API Holdings) | IPO plans shelved after valuation markdown. Focused on restructuring. Reminder that not every unlisted company reaches a successful IPO. |
CSK (Chennai Super Kings) | Not on an active IPO track currently. Investors rely on dividends and potential future liquidity rather than a near-term IPO. |
MSEI (Metropolitan Stock Exchange) | Regulatory considerations complicate listing for a stock exchange entity. Long-term hold for most investors. |
Polymatech Electronics | Semiconductor sector with long gestation period. IPO timing will depend on business scale and market conditions. |
What Triggers an IPO — and What Delays It?
Understanding what makes a company move toward or away from an IPO helps you assess the outlook for any unlisted share you hold:
IPO Accelerators | IPO Delayers / Blockers |
Strong revenue growth and improving profitability | Persistent losses with no path to profitability |
Buoyant market conditions and strong IPO market sentiment | Weak market conditions or poor sentiment for the sector |
VC/PE investors pushing for exit after long holding period | Promoter preference to stay private and avoid disclosure requirements |
Strategic need to raise capital for expansion | Regulatory issues or pending legal proceedings |
Competitors listing and getting strong valuations | Valuation expectations too high vs what public markets will pay |
Strong grey market premium and retail investor interest | SEBI queries or objections to DRHP disclosures |
What If the Company Never Lists?
This is an important scenario to think through before investing. Not every unlisted company will have an IPO. Possible outcomes if a company stays private:
Strategic acquisition — the company is bought by a larger player. Your shares are acquired at a negotiated price. This can be at a premium or a discount to your purchase price depending on the deal.
Continued unlisted market trading — you can still sell in the informal unlisted market, but liquidity depends entirely on buyer demand.
Company winds down — in a worst case, the company fails or is dissolved. As a shareholder, you rank below creditors in recovery.
Long-term hold with dividend income — some mature unlisted companies like CSK provide value through dividends even without an IPO.
This is why we always recommend not making an IPO your only exit plan. Know your alternatives before you invest.
Key Takeaways
The IPO journey has 10 clear stages, from board approval to listing day — and typically takes 3 to 4 months from DRHP filing to listing.
The DRHP filing is the critical signal — the moment it is public, the unlisted market for that company freezes.
After listing, your pre-IPO shares are locked in for 6 months (Mainboard) or 1 year (SME) before you can sell.
NSE, Zepto, OYO, PharmEasy, and CSK represent very different stages and outcomes on the IPO journey — no two are the same.
An IPO is not guaranteed. Always know your alternative exit scenarios before investing.
