O'Melveny & Myers

What O'Melveny & Myers does

O'Melveny & Myers LLP is a full-service global law firm founded in 1885 and headquartered in Los Angeles, organized as a privately held limited liability partnership with no parent company or external institutional investors. The firm operates 18 offices across the United States (Los Angeles, New York, San Francisco, Washington DC, Newport Beach, plus additional US sites), Asia (Beijing, Hong Kong, Shanghai, Seoul, Singapore), and Latin America, with the Tokyo office closed in 2025 after nearly four decades. Service delivery is anchored on three core practice groups — Corporate & Transactions (M&A, private equity, capital markets, project finance), Litigation & Investigations (civil and criminal litigation, government investigations, white collar defense, internal investigations), and Regulatory & Advisory (compliance, crisis management, government relations) — supplemented by specialized industry practices in AI, sports, water, food and beverage, REITs, real estate, and tax, plus regional practices for China, Korea, and Latin America.

The firm generates revenue through traditional professional services and transaction-based fees: hourly billing for litigation, regulatory, and advisory work; transaction-based fees for M&A, IPOs, and capital markets deals (over US$1 billion in represented Hong Kong IPOs in early 2026 alone); and fixed or enhanced fees for complex litigation and investigation matters. Go-to-market is relationship-based, with partners developing enterprise clients (Fortune 500 corporations, financial institutions, governments, and high-net-worth individuals in crisis) through referrals, legal directory rankings, thought leadership, and high-profile case outcomes. Marquee mandates include the LA28 Olympic Committee investigation of Casey Wasserman, Tools for Humanity financial misconduct probe, representation of Goldman Sachs, Walmart, ExxonMobil, Samsung, Hyundai/Kia, SK hynix, and the $2.1 billion Brazos Electric chapter 11 confirmation.

The firm has no proprietary technology product and does not monetize a platform; technology consists of legal-practice tools (document review, e-discovery, practice management). Operational signal is strong: 14 consecutive years on The American Lawyer's A-List, 12 consecutive years in Vault's top three Best Firms to Work For, 97% lawyer pro bono participation (nearly 73,000 hours in 2025), nearly $500,000 in annual scholarship programs, and an aggressive lateral hiring program that has added 51-53 partners since 2023. Leadership comprises Chair Bradley J. Butwin and COO George C. Demos, with former federal prosecutors and DOJ chiefs heading the white collar defense practice globally.
