Understand How Companies Raise Capital Through IPO and Issue Shares

Introduction

Every successful company reaches a point where growth requires more capital than founders, friends, or banks can provide. Building new factories, expanding internationally, acquiring competitors, investing in research and development, or paying down debt often requires hundreds of millions—or even billions—of dollars.

One of the most powerful ways to raise this capital is by issuing shares to the public through an Initial Public Offering (IPO).

However, many people misunderstand what actually happens during an IPO. Some believe companies "sell themselves," while others assume existing shareholders receive all the money. In reality, the IPO process is carefully structured, involving new share issuance, existing shareholder sales, investment banks, regulators, institutional investors, and public markets.

This article explains, step by step, how companies issue shares and raise capital through an IPO, from the formation of the company to becoming a publicly traded corporation.

Chapter 1: The Basics of Company Ownership

Every company has owners.

Ownership is represented by shares (or stock).

Imagine a company worth $1,000,000.

The founders decide to divide ownership into 1,000,000 shares.

Each share represents:

1 / 1,000,000 ownership of the business

If Alice owns 600,000 shares:

• Ownership = 60%

Bob owns 300,000 shares

• Ownership = 30%

Carol owns 100,000 shares

• Ownership = 10%

Together they own 100% of the company.

Why Shares Exist

Shares make ownership easy to divide.

Instead of saying:

Alice owns 60% of the company

we simply say

Alice owns 600,000 shares.

This allows ownership to be transferred easily.

Chapter 2: Why Companies Need More Capital

Suppose the business becomes successful.

Current financial position:

Revenue: $100 million

Profit: $15 million

The CEO wants to:

• Build two new factories

• Expand to Europe

• Open offices in Asia

• Invest in AI technology

Total investment required:

$500 million

Unfortunately,

The company only has:

Cash: $80 million

Bank loan capacity: $120 million

Still needs:

$300 million

Where can this money come from?

Four Common Sources

1. Founder contributes more money

Often impossible.

2. Borrow from banks

Creates debt.

Must pay interest.

Higher financial risk.

3. Private investors

Sell ownership privately.

Examples:

• Venture Capital

• Private Equity

• Strategic Investors

4. Sell shares to the public

This is called an

Initial Public Offering (IPO)

Chapter 3: What Is an IPO?

IPO stands for

Initial Public Offering

It is the first time a private company offers shares to the general public.

Before IPO:

Only founders and investors own shares.

After IPO:

Anyone can become a shareholder.

Example

Before IPO

Shareholder	Shares
Founder	7 million
VC Fund	3 million
Total	10 million

No public investors exist.

After IPO:

The company issues additional shares.

Chapter 4: How New Shares Are Created

Suppose the company currently has

10 million shares.

Management decides to issue

2 million new shares.

Total shares become

12 million.

Notice:

The company created new shares.

These did not previously exist.

This process is called

Primary Share Issuance

Chapter 5: Where Does Investor Money Go?

This is one of the biggest misconceptions.

Suppose IPO price

$50/share

New shares issued

2 million

Money raised

2 million × $50

= $100 million

Who receives the $100 million?

The answer is:

The company.

The cash goes onto the company's balance sheet.

Example:

Before IPO

Cash = $20 million

After IPO

Cash = $120 million

The company can now invest in expansion.

Chapter 6: What Happens to Existing Shareholders?

Suppose:

Founder owned

7 million shares

Before IPO

Ownership:

70%

After issuing 2 million new shares:

Founder still owns

7 million shares

But total shares become

12 million.

New ownership

7 / 12

= 58.3%

This is called

Ownership Dilution

The founder owns the same number of shares but a smaller percentage of the company.

Chapter 7: Primary vs Secondary Shares

An IPO may contain two different types of shares.

Primary Shares

Newly created.

Money goes to company.

Used to raise capital.

Example

Company creates

5 million shares.

Investor pays

$250 million.

Company receives

$250 million.

Secondary Shares

Already owned by existing shareholders.

Founder sells personal shares.

Money goes directly to founder.

Company receives nothing.

Example

Founder sells

1 million shares.

Investor pays

$50 million.

Founder receives

$50 million.

Combined IPO

Many IPOs include both.

Example

Primary:

Company issues

10 million shares

Raises

$400 million

Secondary

Founder sells

2 million shares

Receives

$80 million

Total IPO size

$480 million

Company only receives

$400 million.

Chapter 8: Who Determines the IPO Price?

The IPO price is not random.

Investment banks perform valuation using methods such as:

• Discounted Cash Flow (DCF)

• Comparable Companies Analysis

• Precedent Transactions

• Revenue Multiples

• EBITDA Multiples

• Earnings Multiples

Example

Estimated value

$5 billion

Shares after IPO

100 million

Estimated price

$50/share

Chapter 9: Book Building

Before the IPO,

investment banks contact institutional investors.

Questions include:

• How many shares would you buy?

• At what price?

• What is the demand?

This process is called

Book Building.

Example

Demand

Investor	Shares Wanted
Pension Fund A	5 million
Mutual Fund B	3 million
Insurance Company C	2 million

Total demand

10 million shares

Company only plans to sell

5 million.

The IPO is

Oversubscribed

This usually indicates strong investor interest.

Chapter 10: What Investment Banks Do

Investment banks serve as underwriters.

Their responsibilities include:

• Financial due diligence

• Business valuation

• Preparing IPO documents

• Drafting the prospectus

• Marketing the IPO

• Conducting investor roadshows

• Book building

• Allocating shares

• Stabilizing the stock after listing

They earn underwriting fees, often a percentage of the capital raised.

Chapter 11: What Is a Prospectus?

Before investing,

the public receives a detailed document called a prospectus.

Typical contents include:

• Company history

• Business model

• Industry overview

• Competitive landscape

• Financial statements

• Management discussion

• Risk factors

• Corporate governance

• Use of IPO proceeds

• Dividend policy

• Legal matters

The prospectus helps investors make informed decisions.

Chapter 12: IPO Timeline

Stage	Description
Company prepares	Improves governance, audits financial statements, strengthens internal controls
Hire advisors	Investment banks, lawyers, auditors, tax advisors
Due diligence	Review legal, financial, tax, and operational matters
Draft prospectus	Prepare regulatory filings and disclosures
Regulatory review	Securities regulator reviews the application
Roadshow	Management presents to institutional investors
Book building	Collect investor demand and determine pricing
Pricing	Final IPO price and allocation are set
Listing	Shares begin trading on the stock exchange

Chapter 13: Life After the IPO

Once listed, the company has ongoing obligations.

These include:

• Quarterly and annual financial reporting

• Continuous disclosure of material information

• Investor relations activities

• Annual shareholder meetings

• Compliance with listing rules

• Independent board oversight

• Internal controls and audit requirements

Being public provides greater access to capital but also increases scrutiny.

Chapter 14: Advantages of an IPO

For the Company

• Raise substantial capital

• Enhance brand recognition

• Increase credibility

• Use shares as acquisition currency

• Attract and retain employees through equity compensation

• Improve access to future financing

For Investors

• Opportunity to invest in growing businesses

• Liquidity through public markets

• Transparency via regular disclosures

• Potential capital appreciation and dividends

Chapter 15: Disadvantages of an IPO

Higher Costs

• Legal fees

• Audit fees

• Underwriting fees

• Listing fees

• Investor relations costs

Regulatory Burden

Public companies must comply with extensive reporting and governance requirements.

Market Pressure

Management is often evaluated based on quarterly performance, which can create pressure to prioritize short-term results.

Dilution

Issuing new shares reduces the ownership percentage of existing shareholders unless they participate in the offering.

Chapter 16: Example of a Complete IPO

Consider ABC Technology, a fast-growing software company.

Before IPO

Item	Value
Shares Outstanding	100 million
Founder Ownership	60 million (60%)
Venture Capital Investors	40 million (40%)
Company Valuation	$2 billion

The company plans to expand globally and requires $500 million in new capital.

IPO Structure

• New shares issued: 25 million

• IPO price: $20 per share

• Primary proceeds: $500 million

• Existing shareholders do not sell any shares in this example.

After IPO

Item	Value
Total Shares Outstanding	125 million
Founder Shares	60 million
Founder Ownership	48%
Venture Capital Ownership	32%
Public Investors	20%
Cash Raised by Company	$500 million

The founders retain the same number of shares, but their ownership percentage decreases because additional shares were issued.

Chapter 17: IPO vs Follow-on Offerings

An IPO is only the beginning of a company's journey in the capital markets.

After becoming public, companies can continue to raise capital through:

• Follow-on Public Offerings (FPOs): Issuing additional shares after the IPO.

• Rights Issues: Offering existing shareholders the opportunity to buy new shares, often at a discount.

• Private Placements: Selling shares to selected institutional investors.

• Convertible Bonds: Debt instruments that can later be converted into equity.

These financing options provide flexibility as the company grows and its capital needs evolve.

Key Takeaways

• An IPO (Initial Public Offering) is the first sale of a company's shares to the public.

• Companies raise new capital by issuing primary shares, with proceeds going directly to the business.

• Existing shareholders can also sell secondary shares, with proceeds going to the selling shareholders rather than the company.

• Issuing new shares increases the total number of shares outstanding and may dilute existing ownership percentages.

• Investment banks play a central role in valuation, underwriting, book building, pricing, and marketing the IPO.

• A successful IPO requires strong corporate governance, audited financial statements, comprehensive disclosures, and compliance with securities regulations.

• Going public provides access to substantial funding and broader ownership but also brings increased regulatory obligations, reporting requirements, and market scrutiny.

Conclusion

An IPO is far more than a ceremonial stock exchange listing—it is a transformational event that reshapes a company's ownership, governance, financing capabilities, and relationship with investors. By issuing shares to the public, businesses gain access to significant growth capital while inviting a broader community of shareholders to participate in their future success.

Understanding the mechanics of share issuance, dilution, primary versus secondary offerings, valuation, and the IPO process helps entrepreneurs, finance professionals, students, and investors better appreciate how modern capital markets fuel business expansion. Whether you aspire to build a company, invest in one, or advise clients on corporate finance, mastering the fundamentals of IPOs provides valuable insight into one of the most important milestones in a company's lifecycle.
