McDermott Will & Schulte

McDermott Will & Schulte's Top Stability & Growth Strengths

Strong Revenue Growth: Revenue is described as roughly $2.99 billion in 2025, materially above both legacy McDermott’s prior year and the two legacy firms’ combined 2024, indicating real top-line expansion. Preliminary industry coverage also notes prior momentum at the legacy firm through 2024, providing a solid base for comparison.

Market Expansion: Geographic scale is accelerating with a new Nashville office, significant New York space additions, and notable London growth, alongside expanding recognition in UK/EMEA directories. Hiring activity and modest headcount gains into 2026 further support an expansionary posture across priority markets.

Future-Ready Strategy: The firm is assessing outside capital via an MSO structure and positioning major office investments as foundations for future growth. These moves suggest planning for longer-term demand in areas like healthcare, tax, funds, and related regulated-industry work.
