A&O Shearman

Introducing A&O Shearman

Unparalleled global depth for a changing world. Today more than ever, local business concerns can have international dimensions. We offer unmatched international presence and a deep range of specialization for any and every client need with the ability to draw on domain experts across market, sectors and legal disciplines to provide holistic perspective and advice to any engagement to drive home your advantage.

A&O Shearman was formed in 2024 via the merger of two historic firms, Allen & Overy and Shearman & Sterling.

With nearly 4,000 lawyers globally, we are equally fluent in English law, U.S. law and the laws of the world’s most dynamic markets. This combination creates a new kind of law firm, one built to achieve unparalleled outcomes for our clients on their most complex, multijurisdictional matters – everywhere in the world.

Our lawyers have long enjoyed a reputation for cultivating powerful relationships, thriving on seamless collaboration with each other and with their clients and earning the right to be trusted advisors.

Our clients benefit from the collective experience of teams who work with many of the world’s most influential companies and institutions and have a history of precedent-setting innovations.

We regularly work on complex cross-border transactions, ground breaking new legal solutions and products and help leading client organizations resolve their most difficult disputes. Our lawyers advise more than a third of NYSE-listed businesses, a fifth of the NASDAQ and a notable proportion of the London Stock Exchange, the Euronext, Euronext Paris and the Tokyo and Hong Kong Stock Exchanges.

This experience and expertise creates a firm with the power to shape our clients’ futures and apply the law in ground breaking ways – whether through innovative thinking or new products, services and technologies.

Our fluency in English, U.S., and global law enables us to provide unmatched insight and seamless delivery to clients. Our teams receive regular accolades for the outcomes we deliver, and our client list reflects our status as the third-largest global law firm.
