Common Investment Banking Services

At its core, investment banking acts as a highly specialized bridge. On one side, you have corporations, governments, and institutional clients who need capital to grow or strategic guidance to restructure. On the other side, you have investors looking for opportunities to deploy their cash.

While most people associate investment banking purely with high-profile Wall Street deals, their day-to-day service offerings cover a broad spectrum of complex corporate finance activities.

1. Capital Raising & Underwriting

When a company wants to expand, build a new factory, or acquire a competitor, it needs capital. Investment banks help them raise this money in two primary ways: issuing stock (equity) or issuing bonds (debt). The process of managing this risk and coordinating the sale is known as underwriting.

• Equity Capital Markets (ECM): Banks assist companies in going public via an Initial Public Offering (IPO) or raising more money later through secondary offerings. When British chip-design giant Arm Holdings went public on the Nasdaq, major global investment banks like Barclays, Goldman Sachs, JPMorgan Chase, and Mizuho acted as lead underwriters, pricing the offering, managing the risk, and drumming up demand from institutional investors worldwide.
• Debt Capital Markets (DCM): Instead of giving up ownership, companies or governments might issue bonds to borrow money from the market. State-backed energy giants, such as Saudi Aramco, regularly work with global consortia of investment banks to underwrite multi-billion dollar international bond sales to fund capital expenditures and energy transitions.

2. Mergers & Acquisitions (M&A) Advisory

This is perhaps the most famous service. Investment banks act as strategic matchmakers and negotiators when companies want to buy another business (an acquisition) or combine with one (a merger).

• Sell-Side Advisory: The bank helps a business owner package their company, find qualified buyers, and negotiate the highest possible valuation and best terms.
• Buy-Side Advisory: The bank represents a company looking to expand, helping them identify acquisition targets, run financial valuations, structure the deal, and secure the financing required to close it.

Real-World Example: When Swiss food and beverage giant Nestlé sold its US confectionery business to Italy’s Ferrero Group for $2.8 billion, investment bankers on both sides meticulously modeled the synergies, structured the cross-border tax considerations, and facilitated the transaction.

3. Corporate Restructuring & Advisory

Not all business advice is about growth; sometimes it is about survival. When a company is struggling with heavy debt, facing bankruptcy, or experiencing a major market downturn, investment banks provide restructuring services.

They analyze the balance sheet, negotiate with creditors to adjust payment terms, and help the firm spin off non-performing business units to stay afloat.

Real-World Example: During its massive liquidity crisis, the Chinese real estate conglomerate China Evergrande Group engaged international financial restructuring advisors, including Houlihan Lokey, to negotiate with offshore bondholders and restructure its massive liabilities.

4. Sales & Trading

While corporate finance advisory is a long-term process, the Sales and Trading (S&T) desk operates in real-time. Investment banks run trading desks to buy and sell stocks, bonds, currencies, commodities, and complex derivatives.

They serve two primary functions here:

• Market Making: Providing liquidity by being ready to buy or sell a security at any given time, ensuring institutional clients can trade smoothly.
• Execution: Acting as agents to execute large block trades for institutional investors like pension funds or mutual funds without dramatically shifting the market price.

5. Equity and Fixed-Income Research

To support their sales, trading, and advisory divisions, investment banks employ armies of analysts who produce industry and security research. They publish detailed reports analyzing macroeconomic trends, industry sectors, and individual company financials, assigning “Buy,” “Hold,” or “Sell” ratings.

While research does not make money directly, it is highly valued by hedge funds and asset managers, who route their trading business to banks that provide the most insightful analysis.
