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.

A barbell with almost nothing in the middle: 95 firms hold 79% of the employment — the bulge brackets and large broker-dealers — while 84% of firms have fewer than 20 people. Those small shops are the independent advisors, and they are the acquirable universe; the top of this market is not for sale. No revenue figure is published because advisory fees are reported bundled with securities dealing and trading, which would overstate the advisory market several times over.

One of the most geographically concentrated businesses in the index. Connecticut carries more than twice the investment-banking firms its population implies — Greenwich and Stamford — with New York, Illinois and Massachusetts close behind. Unlike most concentrations in this sector, this one is not about cost: these are the four places where deal capital and the people who price it actually sit.
