Peltier Juvigny Marpeau & Associés
Client SatisfactionPeltier Juvigny Marpeau & Associés combines strong advisory and contentious skills to handle high-profile and strategic competition matters at both French and European level. Merger control is a clear area of expertise for the team, which has recently represented a number of leading French-based multinationals before the FCA and EC in relation to complex transactions, while sensitive antitrust investigations and related litigation also make up a significant proportion of the firm’s caseload. Thibault Reymond, an expert practitioner in both merger control and antitrust litigation, and Ning-Ly Seng, who particularly stands out for her strength in high-end merger control cases, lead the practice.
