Cleary Gottlieb Steen & Hamilton offers large resources and high-level expertise to many of France’s leading listed companies, which turn to the team for support in high-end transactions. Its client base also extends to investors and underwriters, and the firm routinely advises on large IPO and rights offerings on Euronext, European and international listings, and other ECM transactions. Its extensive proficiency in securities law also makes it a top name for high-end public M&A, governance, and stock-market litigation issues. The practice is co-headed by Marie-Laurence Tibi and Frédéric Martin, who was elevated to the partnership in 2025. Also recommended is John Brinitzer, M&A star Pierre-Yves Chabert and Alexis Raguet, who was also promoted to partner early 2025.
