Investment Banking Overview

Overview of the investment banking industry

What is Investment Banking?

Investment banking is the division of a bank or financial institution that serves governments, corporations, and institutions by providing underwriting (capital raising) and mergers and acquisitions (M&A) advisory services. Investment banks act as intermediaries between investors (who have money to invest) and corporations (who require capital to grow and run their businesses). This guide will cover what investment banking is and what investment bankers actually do.

What Do Investment Banks Do?

There can sometimes be confusion between an investment bank and the investment banking division (IBD) of a bank. Full-service investment banks offer a wide range of services that include underwriting, M&A, sales and trading, equity research, asset management, commercial banking, and retail banking. The investment banking division of a bank provides only the underwriting and M&A advisory services.

Full-service banks offer the following services:

• Underwriting – Capital raising and underwriting groups work between investors and companies that want to raise money or go public via the IPO process. This function serves the primary market or “new capital”.
• Mergers & Acquisitions (M&A) – Advisory roles for both buyers and sellers of businesses, managing the M&A process start to finish.
• Sales & Trading – Matching up buyers and sellers of securities in the secondary market.  Sales and trading groups in investment banking act as agents for clients and also can trade the firm’s own capital.
• Equity Research – The equity research group research, or “coverage”, of securities helps investors make investment decisions and supports trading of stocks.
• Asset Management – Managing investments for a wide range of investors including institutions and individuals, across a wide range of investment styles.

Underwriting Services in Investment Banking

Underwriting is the process of raising capital through selling stocks or bonds to investors (e.g., an initial public offering IPO) on behalf of corporations or other entities. Businesses need money to operate and grow their businesses, and the bankers help them get that money by marketing the company to investors.

There are generally three types of underwriting:

• Firm Commitment – The underwriter agrees to buy the entire issue and assume full financial responsibility for any unsold shares.
• Best Efforts – Underwriter commits to selling as much of the issue as possible at the agreed-upon offering price but can return any unsold shares to the issuer without financial responsibility.
• All-or-None – If the entire issue cannot be sold at the offering price, the deal is called off and the issuing company receives nothing.

Once the bank has started marketing the offering, the following book-building steps are taken to price and complete the deal.

M&A Advisory Services

Mergers and acquisitions (M&A) advisory is the process of helping corporations and institutions find, evaluate, and complete acquisitions of businesses. This is a key function in i-banking. Banks use their extensive networks and relationships to find opportunities and help negotiate on their client’s behalf. Bankers advise on both sides of M&A transactions, representing either the “buy-side” or the “sell-side” of the deal.

Below is an overview of the 10-step mergers and acquisitions process.

Banking Clients

Investment bankers advise a wide range of clients on their capital raising and M&A needs. These clients can be located around the world.

Investment banks’ clients include:

• Governments – Investment banks work with governments to raise money, trade securities, and buy or sell crown corporations.
• Corporations – Bankers work with both private and public companies to help them go public (IPO), raise additional capital, grow their businesses, make acquisitions, sell business units, and provide research for them and general corporate finance advice.
• Institutions – Banks work with institutional investors who manage other people’s money to help them trade securities and provide research. They also work with private equity firms to help them acquire portfolio companies and exit those positions by either selling to a strategic buyer or via an IPO.

Investment Banking Skills

I-banking work requires a lot of financial modeling and valuation.  Whether for underwriting or M&A activities, Analysts and Associates at banks spend a lot of time in Excel, building financial models and using various valuation methods to advise their clients and complete deals.

Investment banking requires the following skills:

• Financial modeling – Performing a wide range of financial modeling activities such as building 3-statement models, discounted cash flow (DCF) models, LBO models, and other types of financial models.
• Business valuation – Using a wide range of valuation methods such as comparable company analysis, precedent transactions, and DCF analysis.
• Pitchbooks and presentations – Building pitchbooks and PPT presentations from scratch to pitch ideas to prospective clients and win new business (check out CFI’s Pitchbook Course).
• Transaction documents – Preparing documents such as a confidential information memorandum (CIM), investment teaser, term sheet, confidentiality agreement, building a data room, and much more (check out CFI’s library of free transaction templates).
• Relationship management – Working with existing clients to successfully close a deal and make sure clients are happy with the service being provided.
• Sales and business development – Constantly meeting with prospective clients to pitch them ideas, offer them support in their work, and provide value-added advice that will ultimately win new business.
• Negotiation – Being a major factor in the negotiation tactics between buyers and sellers in a transaction and helping clients maximize value creation.
