Investment Banking and Capital Raising: Understanding IPO Deal Processes

 Companies often need to raise capital to fund expansion, repay debt, invest in new projects, or support their growth plans. Investment banks help companies evaluate financing options and connect with investors while supporting the planning and execution of these transactions.

An IPO is one of the most visible forms of capital raising, but taking a company public involves much more than issuing shares. Investment bankers may be involved in valuation, due diligence, documentation, investor marketing, book building, pricing, and transaction execution. Understanding the IPO deal process helps you see how these different activities come together in investment banking.

What Is Investment Banking in Capital Raising?

Companies may need capital to fund expansion, repay debt, invest in new projects, or support other business objectives. Investment banks help companies access investors and manage transactions through which securities are offered to raise funds.

What Does an Investment Bank Do in a Capital-Raising Deal?

  1. Advises the company: The bank helps assess the transaction, market conditions, potential investor demand, and issue structure.

  2. Helps prepare the offering: Investment bankers work with the company and other professional advisors on information and documents required for the transaction.

  3. Assesses investor demand: Bankers analyse market conditions, comparable offerings, investor appetite, and other factors that can influence the issue.

  4. Markets the offering: The banking team helps present the company and the investment opportunity to potential investors.

  5. Supports pricing and allocation: The bank works with the issuer during the book-building and pricing process and helps coordinate the eventual allocation of shares.

What Are the Main Types of Capital Raising?

Capital raising does not always mean launching an IPO. Companies can use different routes depending on their stage, funding requirements, ownership considerations, and market conditions.

Capital-Raising Method

How It Works

Typical Purpose

IPO

Shares are offered to public investors for the first time

Raise capital and become publicly listed

Follow-on offering

A public company issues additional shares

Raise additional equity capital

Private placement

Securities are sold to selected investors rather than through a broad public offering

Raise capital without a public issue

Debt issuance

The company raises funds by issuing debt securities

Fund operations, expansion, or other requirements

Rights issue

Existing shareholders receive an opportunity to subscribe to additional shares

Raise equity from existing shareholders

The exact regulatory requirements depend on the jurisdiction and type of transaction. In the US, for example, registered offerings require a registration statement before securities can generally be offered for sale, while Indian public issues follow the applicable SEBI and stock-exchange framework.

How Does an IPO Deal Process Start?

An IPO usually begins well before investors can place bids. The company first assesses whether it is prepared to enter the public market and works with professional advisors and investment banks.

1. Select Investment Bankers

The company appoints investment banks or merchant bankers to advise on the transaction and manage the offering. The choice may depend on factors such as industry experience, distribution capabilities, transaction experience, and relationships with investors.

2. Conduct Due Diligence

The company, investment bankers, lawyers, accountants, and other advisors review important business, financial, legal, and operational information. This helps identify issues that need to be addressed before the offering.

3. Prepare the Offer Documents

The company prepares the required disclosures and offer documents containing information about its business, financial position, management, risks, and the proposed offering. In India, the IPO process includes documents such as the Draft Red Herring Prospectus (DRHP) and Red Herring Prospectus (RHP).

4. Regulatory Review and Approvals

The relevant documents are submitted to the applicable regulators and exchanges. The exact review process varies by market. For example, the SEC may review registration filings in the US, while Indian IPOs operate under SEBI regulations and applicable stock-exchange requirements.

How Does Book Building Help Set the IPO Price?

Book building is one of the key stages of an IPO because it helps discover the price at which shares can be offered based on investor demand.

In India, the company and its BRLMs establish a price band. Investors then submit bids indicating the number of shares they want and the price they are willing to pay within that band. After the bidding period closes, demand at different price levels is assessed, and the final issue price is determined.

How Book Building Works

Stage

What Happens

Price band

A range within which investors can place bids is announced

Investor bidding

Investors submit bids for a specified number of shares

Demand analysis

Investment bankers and the issuer review demand at different prices

Price discovery

The final issue price is determined based on the bidding process

Allotment

Shares are allocated to successful applicants according to applicable rules

The book-building process therefore connects investor demand with IPO pricing, rather than simply assigning a price without considering the bids received.

What Role Does Underwriting Play in an IPO?

Underwriting is an important part of investment banking because the underwriter helps the company sell the securities to investors. Depending on the agreement, the underwriter may also take on different levels of responsibility for the securities that are being offered.

Common underwriting arrangements include:

  1. Firm commitment: The underwriter agrees to purchase the entire offering from the issuer and then resell the securities to investors, taking responsibility for shares that remain unsold.

  2. Best efforts: The underwriter agrees to use its efforts to sell the securities but does not guarantee that the entire issue will be sold.

  3. All-or-none: The transaction proceeds only if the entire specified offering can be sold under the agreed terms.

The exact underwriting arrangements and terminology can differ across markets and transactions.

What Happens After IPO Pricing?

Once the final price is determined, the transaction moves toward allotment and listing. Investors who receive an allocation are issued shares according to the applicable allocation rules, while amounts associated with unsuccessful or excess applications are released or refunded as applicable.

After the shares are listed, they can be traded in the secondary market. The company also takes on ongoing obligations as a public company, including applicable financial reporting and disclosure requirements.

Key Stages After Book Building

  • Final pricing: The issue price is determined after the bidding process.

  • Share allotment: Shares are allocated to investors according to the applicable rules.

  • Listing: The company's shares begin trading on the stock exchange.

  • Post-listing compliance: The company follows continuing disclosure, reporting, governance, and listing requirements.
