An Initial Public Offering (IPO) is one of the most significant milestones in a company's journey. It marks the transition from being privately owned to becoming a publicly traded company whose shares can be purchased by investors through the stock exchange. For businesses, an IPO is a powerful way to raise capital for expansion, innovation, debt reduction, and long-term growth. For investors, it presents an opportunity to own shares in a company at the beginning of its public market journey.
Understanding how IPOs work is essential for anyone interested in stock market investing. Whether you are a beginner, a retail investor, or someone looking to diversify your investment portfolio, this guide explains the complete IPO process, from company preparation to public subscription, in a simple and comprehensive manner.
What Is an Initial Public Offering (IPO)?
An Initial Public Offering (IPO) is the first time a private company offers its shares to the public through a stock exchange. Before an IPO, ownership usually belongs to founders, early investors, venture capital firms, or private shareholders.
After completing the IPO process, the company's shares become publicly tradable, allowing anyone meeting the investment requirements to purchase ownership in the company.
An IPO serves multiple purposes, including:
Raising capital for business expansion
Funding research and development
Launching new products or services
Reducing existing debt
Increasing public credibility
Providing liquidity for existing shareholders
Once listed, the company's stock price fluctuates according to market demand, company performance, and investor sentiment.
Why Companies Choose to Go Public
Companies usually decide to go public when they reach a stage where additional funding is required to support future growth.
Some common reasons include:
Expanding operations nationally or internationally
Building new manufacturing facilities
Investing in technology and innovation
Acquiring competitors
Increasing working capital
Enhancing brand reputation
Creating opportunities for future fundraising
Going public also increases transparency because listed companies must regularly disclose financial statements and comply with regulatory requirements.
Legal Requirements Before Launching an IPO
Before offering shares to investors, companies must satisfy several legal and regulatory conditions.
These requirements generally include:
Approval from the Securities Regulator
Every company planning an IPO must obtain approval from the country's Securities and Exchange Commission (SEC) or the relevant capital market regulator.
The regulator carefully reviews:
Financial statements
Business operations
Corporate governance
Risk disclosures
Shareholding structure
Prospectus
Only after meeting all regulatory standards can the company proceed with the IPO.
Appointment of an Investment Bank
An investment bank plays a central role throughout the IPO process.
Its responsibilities include:
Managing the IPO process
Advising the company
Preparing legal documentation
Determining the pricing strategy
Marketing the IPO
Coordinating investor participation
Managing subscriptions
The investment bank acts as the bridge between the issuing company and investors.
Understanding the IPO Process Step by Step
The IPO process generally takes place in multiple stages.
Let's examine each phase in detail.
Phase One: Book Building (Bidding Process)
The first stage of many IPOs is known as the Book Building Process.
Rather than immediately selling shares to everyone, the company first invites institutional and high-net-worth investors to submit bids.
This process helps determine the market value of the shares before opening subscriptions to the general public.
Who Can Participate in Book Building?
Book building is generally available to:
Institutional investors
Mutual funds
Insurance companies
Pension funds
Asset management companies
High-net-worth individuals (HNWIs)
These investors often purchase larger quantities of shares compared to retail investors.
How the Bidding Process Works
The company announces a bidding period that usually remains open for two business days.
Instead of announcing one fixed share price, the company specifies:
Floor Price (Minimum Price)
Upper Price Limit (Maximum Price)
Investors submit bids within this approved price range.
Bids below the minimum or above the maximum price are not accepted.
After the bidding period ends, the investment bank evaluates all bids and determines the final offer price based on investor demand.
Registration Requirements for Book Building
Eligible investors typically complete several formalities before participating.
These may include:
Filling out a registration form
Providing identification documents
Submitting required declarations
Depositing funds or providing a cross cheque (subject to applicable regulations and minimum requirements set for the IPO)
Registering with the appointed investment bank
After successful registration, investors receive secure login credentials.
Online Bidding Platform
Modern IPO systems have largely shifted to digital platforms.
Once registered, investors receive:
Login ID
Password
Access to the investment bank's online bidding portal
Using this portal, investors can:
View active IPOs
Submit bids
Modify bids before closing
Monitor bidding status
Receive confirmation of participation
Digital bidding has significantly improved efficiency and transparency.
Phase Two: Retail Investor Subscription
After completion of book building, the IPO enters the General Public Subscription Phase.
This stage is specifically designed for retail investors, allowing smaller investors to purchase shares.
Retail investors can subscribe without participating in the earlier bidding process.
How Is the Final Share Price Determined?
One of the most important features of book-built IPOs is pricing fairness.
The final price paid by retail investors is generally the same price established through the institutional bidding process.
This pricing mechanism ensures:
Transparency
Fair treatment
Equal pricing for all investors
Better market confidence
Retail investors benefit from the market-driven valuation established during book building.
Methods to Subscribe to an IPO
There are generally two primary ways investors can subscribe to an IPO.
Method 1: Physical IPO Subscription
Although online investing is growing rapidly, physical applications remain available in many jurisdictions.
The process usually includes:
Step 1
Collect the IPO application form.
Step 2
Fill in:
Personal information
Investor account details
Number of shares requested
Payment information
Step 3
Submit the completed form to an authorized listed bank designated for that specific IPO.
Step 4
Complete payment using:
Direct debit from an eligible bank account, where available
Pay order or banker's cheque if your account is with another bank (subject to the IPO's instructions)
After submission, the bank processes the application and forwards it for verification.
Method 2: Electronic IPO (e-IPO) Subscription
The easiest and fastest method today is Electronic IPO (e-IPO).
Electronic systems eliminate paperwork and make investing accessible from virtually anywhere.
How e-IPO Registration Works
Investors first create an account on the official e-IPO platform.
Registration generally requires:
National identity information
Mobile number
Email address
Investor account details
Bank information
After registration, investors can log in and participate in active IPO offerings electronically.
Benefits of Electronic IPO Subscription
Online subscription offers numerous advantages.
These include:
Faster application process
Secure transactions
Reduced paperwork
Easy payment options
Real-time application tracking
Convenient access from home
Improved transparency
Many investors now prefer e-IPO because it simplifies the entire investment experience.
How IPO Shares Are Allocated
Once the subscription period closes, applications are reviewed.
If demand exceeds the number of available shares, allocation is carried out according to the applicable rules and the IPO prospectus. In many markets, shares may be allocated proportionately or through other approved methods, depending on the regulatory framework.
Successful applicants receive:
Confirmation of allotment
Shares credited to their investor account
Information regarding listing dates
Investors who do not receive an allocation generally have their blocked or unused funds released or refunded according to the applicable procedures.
What Happens After the IPO Is Listed?
After completing the IPO process, the company's shares begin trading on the stock exchange.
At this stage:
Investors can buy additional shares.
Existing shareholders may sell their holdings, subject to any applicable lock-up restrictions.
Market prices fluctuate based on supply and demand.
Company performance influences investor confidence.
The first trading day often experiences higher volatility due to market interest.
