A&O Shearman

London, UK / New York, NY·14 offices

Firm Overview

A&O Shearman was formed in 2023 from the merger of Allen & Overy and Shearman & Sterling — combining one of London's oldest Magic Circle firms with one of Wall Street's most storied institutions. The combined firm has approximately 800 partners and 3,000 lawyers globally, making it a true peer of the elite global platforms.

Associate Experience

Associates at A&O Shearman work on genuinely cross-border transactions and disputes in an environment shaped by both Wall Street and Magic Circle traditions. The merger has created new opportunities across geographies and practices, though integration continues.

Lateral Recruiting Context

A&O Shearman is actively recruiting to build out its combined US-UK platform post-merger. For laterals with M&A, finance, or capital markets experience who want global reach, the firm is a compelling and actively growing destination.
