Representing a range of prominent businesses in the technology, telecoms, and financial services sectors, the competition and antitrust practice at Grinberg Cordovil Advogados (GCA) is a trusted adviser for the full spectrum of merger control, behavioural, and compliance matters. The team has built extensive experience handling high-profile and high-value cases, including merger control proceedings, cartel investigations, abuse of dominance allegations, and both leniency and settlement agreements at domestic and multijurisdictional levels. With a comprehensive service offering, the department continues to attract new clients, strengthening its footprint in the IT, agribusiness, and media and entertainment sectors. Mauro Grinberg co-leads the practice with Leonor Cordovil, and is recognised for his broad expertise in investigations involving alleged cartels and administrative misconduct. Cordovil is particularly noted for her leadership in merger control proceedings before CADE, leniency applications, and the development of compliance programmes. On the litigation side, the ‘outstanding’ Karen Ruback is a key contact, while Ricardo Casanova Motta is highly regarded for his expertise in unilateral conduct cases. Beatriz Cravo is also a notable member of the team, who advises on both merger control and investigations.
