With more than 15 years of experience and a dual qualification in France and the UK, Jean-Nicolas Maillard focuses on EU and French competition law.  He advises clients across the whole spectrum of antitrust law and compliance.

He has extensive experience in handling “dawn raids” and in devising creative and tailor-made defense and/or cooperation strategies in cartel and antitrust investigations.  Highlights of his work in this area include:

  • Assisting multinational clients in fourteen European Commission (EC) and French Competition Authority dawn raids and related litigation (including the successful annulment of a dawn raid by the French Courts)
  • Securing full immunity for clients in five leniency procedures at the EC and French Competition Authority
  • Defending clients in numerous antitrust investigations from the French Competition Authority and resolving challenges from the regulators through the negotiation of commitments in two major cases

Mr. Maillard also regularly represents companies in antitrust court litigation, sectoral investigations, and abuse of dominance matters.  He regularly organizes, implements, and manages antitrust compliance initiatives with in-house teams, including risk-mapping and comprehensive antitrust audits. 

In addition, his M&A experience includes advising industry clients, services groups and investment funds in relation to over 100 corporate transactions (mergers, acquisitions, hostile takeovers, disposals, joint ventures) and obtaining merger control clearances from the EC, the French Competition Authority, the UK competition authorities, and other national competition authorities throughout the world in a large number of strategic corporate transactions.  He also works closely with suppliers on all issues connected to the distribution of their products and services.

Throughout his career in Paris, London and Brussels, Mr. Maillard has gained significant exposure to a wide range of business sectors, including food, retail, consumer electronics, financial services and private equity, construction products, agriculture, and pharmaceuticals.
