Wachtell, Lipton, Rosen & Katz

What Wachtell, Lipton, Rosen & Katz does

Wachtell, Lipton, Rosen & Katz is a New York-based, partner-owned limited liability partnership founded in 1965 that provides elite corporate legal counsel to large public companies, financial institutions, private equity sponsors, and REITs. The firm operates through eight integrated practice areas—Corporate/M&A, Litigation, Antitrust, Executive Compensation and Benefits, Intellectual Property, Real Estate M&A, Restructuring and Finance, and Tax—staffed on a task-force basis rather than as modular service lines. Its distinctive operating model combines a low associate-to-partner ratio with lock-step partner compensation, enabling partners to staff and supervise the largest matters directly.

The firm generates revenue primarily through hourly billing and transaction-based fixed fees on high-stakes M&A, takeover defense, shareholder activism, restructuring, and complex litigation mandates. Go-to-market is exclusively through direct partner relationships, law school teaching, thought leadership, and ranking-driven visibility (Vault, Chambers USA, Mergermarket, MergerLinks); the firm does not engage in traditional marketing or reseller channels. Wachtell originated the shareholder rights plan (the 'poison pill') and structured the first cross-border Morris Trust transaction, and participates in most landmark Delaware corporate governance decisions.

Despite a relatively small headcount of 501–1,000, Wachtell consistently ranks near the top of M&A legal advisor tables by deal value—claiming global leadership in Q1 2026 with $236.28 billion across 22 deals—and represents marquee clients including Pfizer, Warner Bros. Discovery, OpenAI, Salesforce, Equity Residential, and the NBA. The firm is concurrently navigating material partner attrition (at least nine departures in two years, predominantly to Latham & Watkins), compensation restructuring, and an M&A practice leadership transition to younger co-chairs, while sustaining elevated deal-flow momentum through 2025 and the first half of 2026.
