More than 170 legacy Allen & Overy (A&O) and Shearman & Sterling partners have left or retired since the two firms’ merger was announced in May 2023, with more than a third of these exits taking place in the US, according to Legal Business research.
Departures tracked by LB from Companies House filings and other data show that 130 partners have left since the union went live in May 2024. This means that around one in six of those who were partners at the firm when the merger went live, have since gone.
