What Shearman & Sterling does
Shearman & Sterling, founded in 1873, was a US-headquartered global law firm advising corporations, financial institutions, governments, and governmental organizations on complex cross-border matters. In 2024 it merged with Allen & Overy to form A&O Shearman, a combined entity operating under a unified partnership structure with nearly 4,000 lawyers and specialists globally, including more than 1,000 finance attorneys across major financial centers, and approximately 40 offices spanning North America, Europe, Asia Pacific, the Middle East, Africa, and Latin America.
The firm operates six core practice areas: Advisory and Regulatory, Capital Markets, Corporate and M&A, Disputes, Finance, and Legal Innovation. Service offerings span high-end transactional work (M&A, joint ventures, corporate reorganizations, debt and equity capital markets, project finance, structured finance), contentious matters (international arbitration, securities litigation, white-collar defense, investigations), and advisory mandates (antitrust, sanctions, foreign investment/CFIUS, data privacy, AI governance, sustainability, restructuring). Legal Innovation is delivered through the Fuse platform and the Markets Innovation Group, which together provide dedicated innovation capability, flexible specialist resourcing, and new product development for capital markets and adjacent practice areas.
Revenue is generated almost exclusively through professional services on enterprise engagements, with custom quote-based pricing tied to matter complexity and scope, billed across hourly, fixed-fee, or hybrid arrangements. Go-to-market is direct and enterprise-led, with reach extended through the global office network and relationships with leading local law firms in jurisdictions where the firm does not maintain a direct office. Marquee mandates include the representation of Sasol Limited on a USD750 million bond issuance and concurrent tender offers and the representation of Stellantis Financial Services US Corp. on a USD2.5 billion notes offering. The firm markets its expertise through published insights, podcasts, global industry outlooks, and client events.
