Mattos Filho is a leading Brazilian law firm headquartered in São Paulo. Established in 1990, the firm is known for representing multinational corporations, financial institutions, and state-owned entities in complex antitrust disputes, cross-border mergers and acquisitions, and high-stakes arbitration proceedings. Mattos Filho has played advisory roles in regulatory frameworks and major transactions involving Brazilian energy, mining, and telecommunications sectors.
Mattos Filho was founded in 1990 amid Brazil's post-Constitution of 1988 economic liberalization and privatization wave that included the Privatization of Telebrás and reforms under Presidents Fernando Collor de Mello and Itamar Franco. In the 1990s the firm built practices supporting clients during the Plano Real stabilization and the rise of Vale (company), Petrobras, and Embraer in international markets. During the 2000s Mattos Filho expanded work in mergers and acquisitions connected to deals by Ambev, Itaú Unibanco, and Banco do Brasil, and became involved in cross-border arbitrations administered by the International Centre for Settlement of Investment Disputes and the London Court of International Arbitration. The firm later advised on regulatory matters arising from decisions by the Administrative Council for Economic Defense and litigation touching on rulings from the Supreme Federal Court (Brazil). Strategic hires and lateral growth linked the firm to global networks including relationships with firms in New York City, London, and Brussels.

The firm acted as counsel in major privatizations, large-scale M&A deals and project finance transactions for infrastructure concessions involving entities such as Vale S.A., Petrobras, and consortiums led by Itaú Unibanco. Mattos Filho represented clients in high-profile antitrust investigations before the Administrative Council for Economic Defense and handled complex arbitration matters under ICC arbitration and UNCITRAL rules related to disputes with multinational investors and state actors. The firm advised on cross-border acquisitions involving Ambev and Anheuser-Busch InBev, capital markets offerings tied to B3 (stock exchange), and financing for renewable energy projects with participation from Iberdrola and Enel. Litigation matters have included appellate work at the Supreme Federal Court (Brazil) and precedent-setting disputes affecting tax regimes and regulatory approvals.
