About A&O Shearman
A&O Shearman was created in 2024 through the combination of Allen & Overy and Shearman & Sterling. Its identity rests on bringing English-law, US-law and local-law capabilities into the same international practice. That combination is particularly relevant to matters involving several legal systems, where a financing, investment or dispute cannot be understood solely through the rules of one country.

The firm serves companies and institutions operating across major financial and commercial markets. Its own overview emphasizes the collective experience of teams advising publicly listed businesses in the United States, Europe and Asia. The distinguishing feature is the interaction between jurisdictions and legal disciplines, rather than simply the existence of overseas offices.
A&O Shearman also publishes material on legal innovation, environmental sustainability and social impact. Those initiatives sit alongside its client practice and help explain how the combined firm presents its longer-term development. Its 2024 formation date is an important distinction when reading older material about either predecessor firm.
