Collated independently by Legal 500 research team.

• Excellent team, with extensive technical and market knowledge. Very helpful and work well as a team.
• The firm stands out for its extremely high technical level, combined with a robust body of knowledge and experience, which supports in-depth strategic discussions. This solid foundation allows not only for the precise evaluation of scenarios, but also for the proposal of well-founded ideas and actions, adding quality and consistency to the decision-making process. It is a team capable of confidently navigating between theory and practice, contributing significantly to the development of sophisticated and effective solutions.
• The firm distinguishes itself in the national legal market through its highly specialized work in restructuring and special situations, with a particular focus on advising sophisticated creditors, including banks, investment funds, and institutional investors. Its value proposition is based on a rare combination of legal excellence, deep financial understanding, and the ability to execute in highly complex and high-pressure scenarios. The quality of service provided is reflected in an eminently strategic approach focused on maximizing recovery, in which each mandate is treated with an integrated vision — from the analysis of the capital structure and guarantees to the definition of negotiation scenarios and enforcement alternatives. The team demonstrates a high capacity for action in critical processes, often involving multiple jurisdictions, different classes of creditors, and situations of significant conflict of interest.
• The firm's restructuring team stands out for its strong performance in advising creditors, including financial institutions, investment funds, and institutional investors, in highly complex contexts. Their approach combines legal rigor with a deep understanding of financial dynamics, enabling them to protect and maximize credit recovery in adverse scenarios. The practice is led by Eduardo Mattar, who is the team's main reference in restructuring mandates. He is distinguished by his strategic vision, strong execution capacity, and results-oriented approach, being particularly recognized for leading complex negotiations involving multiple stakeholders and sophisticated capital structures. His ability to anticipate risks and define effective strategies in stressful situations makes him a trusted interlocutor for creditors in critical processes. Guilherme Barros acts as second-in-command in the restructuring area, playing a central role in structuring and implementing solutions. He is distinguished by his technical expertise, attention to detail, and ability to handle complex financial structures and documentation, ensuring consistency and robustness in defending creditors' interests throughout the entire process. Cesar Rizzo contributes as a strategic support element to the practice, adding value especially in situations that require multidisciplinary coordination and the definition of sophisticated legal strategies. His experience and analytical skills strengthen the team's performance in particularly demanding contexts.
• Mattar is one of the most distinctive practices in the Brazilian restructuring and special situations market. The firm combines deep technical expertise in "recuperações judiciais", out-of-court reorganizations, and complex distressed situations with a genuine ability to devise creative, non-standard solutions — and to execute them effectively. What sets the team apart is not just its legal knowledge, but its practical approach: Mattar consistently brings fresh thinking to difficult mandates and has a strong track record of implementing innovative structures in transactions where conventional approaches are not sufficient. The practice is also notable for the quality of its entire team, not just its leadership. Eduardo Mattar is widely regarded as a standout practitioner in the field, and that standard carries through to the other partners — César Rizzo, for example, is an exceptional lawyer who brings significant depth to the firm's capabilities. Clients can expect consistent quality across all levels of engagement, which is not always a given in a market where institutional strength often lags behind individual reputation. For clients navigating complex restructurings or special situations in Brazil, Mattar offers a rare combination of technical rigor, creative problem-solving, and reliable execution.
• Eduardo Mattar is a leading figure in the field of judicial reorganization, combining technical depth with practical experience in critical situations.
