Sell-Side, Buy-Side, Defence & Fairness Opinions
M&A advisory is the flagship investment banking product. This chapter covers the business of advising on M&A — how mandates are won, processes run, fees structured, and deliverables produced.
Unlike Chapters 11–12, which teach deal mechanics (valuation, structure, negotiation dynamics), this chapter teaches the advisory craft: the relationship dynamics, process management, and judgment calls that define an excellent M&A advisor.
Investment banks advise on roughly $4–5 trillion in M&A globally each year. A portion of that translates to advisory fees ranging from $50M to $500M per deal for the lead advisors. Understanding how those fees are earned — and why some advisors consistently command premium fees — is core to investment banking strategy.
