Lazard and Rothschild & Co are the two oldest names still competing at the top of M&A advisory. Rothschild opened in 1811, Lazard in 1848, and both now sit in the elite boutique tier with perfect 5 out of 5 prestige scores. The similarities are real: both advise governments through dedicated sovereign practices, both run serious restructuring groups, and both hire a small analyst class each year through a first round and a Superday with no HireVue screen.
The split comes down to geography and ownership. Lazard is headquartered in New York, ranks as the world's largest independent financial advisory firm by revenue, and hires an analyst class of 70-90 at a 2-3% acceptance rate. Rothschild is headquartered in Paris and became fully family-controlled again in 2023, when the Rothschild family's Concordia holding company led a 3.7 billion euro going-private deal that took the firm off Euronext Paris. Its class runs 60-80 with a 3-4% acceptance rate.
If you are choosing between them, you are really choosing between a US-anchored advisory career and a European one. This page breaks down where each firm actually wins.
