Strong Revenue Growth: Global revenue is reported to have risen meaningfully year over year to roughly $3.7 billion, with the London office posting more than 30% growth to about $299 million.

Profitability: Profits per equity partner reportedly increased, with figures cited around $5.16 million in one period and approximately $6 million in another. These gains indicate solid margins supported by high-value work in areas such as deals and life sciences.

Market Expansion: Office footprints expanded materially—more than 60% in Dallas—and space was added or expanded in San Francisco, Los Angeles, Tokyo, Miami, Washington, D.C., and New York. Notable lateral partner additions (around 50 in a cited year) further reflect geographic and practice growth.
