Overview

Investment Banking & M&A Advisory firms execute mergers, acquisitions, and capital-raising transactions — buy-side and sell-side mandates, capital markets, and fairness opinions. The field runs from the bulge-bracket banks through elite independent advisors (Evercore, Moelis, Lazard, Centerview) down to thousands of lower-middle-market boutiques.

Revenue is dominated by success fees that pay on close, making the business highly cyclical with deal volume — lucrative in active markets, lean in downturns. Margins are high and capital needs minimal; the binding constraint is senior-banker relationships and sector credibility, which is why the sector churns through lift-outs and new boutique formation.
