The ‘knowledgeable, experienced and client-oriented’ team at Aequo houses a balanced contentious and non-contentious practice that spans the gamut of competition law. A leading firm in merger filings, the group is also regularly called upon for representation in antitrust investigations and advice on regulation, cartels and state aid matters. The team continues to add to its roster of national and international clients and notes a particular influx of clients from the tech sector. Leveraging her specialist knowledge of EU competition law, Mariya Nizhnik is well-placed to advise multinational clients and is particularly adept at antitrust investigations. Denis Lysenko is another key member of the practice. Sergey Denisenko and Anna Litvinova departed in April 2025.
