Marval O’Farrell Mairal’s first-class team stands out for the ‘speed with which it provides answers’ and for its ability to provide ‘clear and concise advice on the possible risks’. On the merger-review side, the firm’s heavyweight corporate practice translates into a steady flow of cases — the firm notably secures the highest volume of merger reviews in the market — and few high-stakes mergers are cleared in Argentina without this team’s involvement. Its close links with major global law firms mark it as a particularly strong performer in cross-border matters, including recent work for household-name multinationals such as Disney, Warner Media and Pfizer. On the investigations front, the group is routinely involved in many of the most sensitive and complex cases conducted by the Antitrust Commission. The third pillar of the practice is compliance, where the team assists with in-house compliance audits and training programmes. High-profile expert Miguel del Pino heads the department and is widely recognised as a market leader. Santiago del Rio is an impressive up-and-coming competition specialist. The team also includes the experienced Gabriela Ariel Irizar and rising star Ignacio Mora — both are associates.
