Katten was listed among the largest US law firms in London in The Lawyer's US 50 2025 Financial Results report, which spotlighted the financial performance of the largest US-headquartered firms in the United Kingdom and included profiles highlighting each firm's financial performance, talent and deals. Each firm was grouped into three categories based on their London revenue in 2024, with Katten recording revenue in London of $29.6 million and a 24.6 percent increase in revenue. The report also distinguished Katten as the second-fastest-growing firm in its cohort.

"Katten's growth has been driven by its strategic focus on serving financial services clients, alongside a growing volume of transactional work, particularly inbound matters from the [United States]," the report stated. "The London team now advises nearly all of Katten's US proprietary trading clients with operations in the City." The report also noted the firm's "targeted lateral hiring" program and its role in raising Katten's profile in London.

"Our strategic hires are a direct response to client feedback and market analysis, reflecting a concrete need for deeper, collaborative [experience] that mirrors and supports our US practices," said London Managing Partner Christopher Hitchins.

The US 50 2025 report sources data and figures from the publication’s most recent US 50 survey, gathered either directly from the firms or estimated through publicly available information and The Lawyer’s historical data.
