What is Investment Banking?

Investment banking is the division of a financial institution that advises companies on major transactions — mergers and acquisitions (M&A), capital raises (IPOs, debt issuances), and restructurings. Unlike commercial banking (which takes deposits and makes loans), investment banks act as intermediaries and advisors, earning fees for helping companies buy other companies, sell themselves, or raise capital from investors. There are two main functions. Advisory (also called M&A) involves advising a company that wants to sell itself (sell-side), a company that wants to acquire another (buy-side), or both. Capital Markets involves helping companies raise money by issuing stocks (equity capital markets, or ECM) or bonds (debt capital markets, or DCM). The largest investment banks — Goldman Sachs, JPMorgan, Morgan Stanley, Bank of America — have all of these capabilities, while boutique firms like Evercore, Lazard, and Centerview focus primarily on advisory. The investment banking team hierarchy runs from Analyst (1-3 years, builds models and presentations), to Associate (3-5 years, manages deal execution), to Vice President (manages client relationships and deal teams), to Managing Director (originates deals and owns client relationships). The work is intense, deadline-driven, and detail-oriented — a single error in a CIM or merger model can derail a multi-billion dollar transaction.

How the Pieces Fit Together

A typical sell-side M&A process follows a structured sequence: the bank is engaged, a teaser is distributed anonymously to potential buyers, interested parties sign NDAs and receive the CIM (the detailed sales document), indications of interest are submitted and reviewed, shortlisted buyers attend management meetings and conduct diligence, final bids are submitted, and the deal moves toward signing and closing. Each stage has specific deliverables, and this plugin provides tools for every step.
