Marcio SoaresMattos Filho

Noted for its ‘knowledge of the industry and recent decisions by CADE‘, the ‘highly qualified, objective and accessible‘ antitrust practice at Mattos Filho is a key port of call for domestic and international heavyweights from the worlds of energy, telecoms, technology, life sciences and financial services, among other sectors. Covering the entire spectrum of competition law matters, the team particularly stands out for its proficiency in complex merger control proceedings; conduct matters, including high-profile cartel and dominance investigations, as well as leniency negotiations, antitrust compliance and lawsuits involving competition issues are other key areas of activity for the department. Marcio Soares is a name to note in the Rio office who maintains a broad practice covering merger reviews, investigations into anti-competitive conduct, antitrust lawsuits and compliance. Based in São Paulo, Lauro Celidonio Neto and Renata Fonseca Zuccolo Giannella have negotiated hundreds of M&A transactions before CADE, and are also well placed to undertake behavioural work. In the same office, Michelle Machado often acts in merger control and leniency negotiations, while associate Ana Carolina Bittar is particularly skilled in unilateral conduct matters and cease-and-desist agreements (TCCs). A key driver behind the firm’s competition practice in Brasília, Eduardo Frade draws on his former experience at several public management agencies to advise clients on merger clearances, cartels, abuse of dominant position cases and antitrust compliance.
