Regarded by many as ‘the best in Argentina’, Marval, O'Farrell & Mairal’s ‘pragmatic approach’, ‘fast delivery’ and ‘tailor-made advice’ sets it apart from its competitors. Miguel del Pino is a is a ‘world class antitrust lawyer’ and heads a two-partner team that also draws on the expertise of senior partner Alfredo O’Farrell. In addition, the team is commended for its ability to ‘attract particularly strong associates’, with Santiago del Rio highlighted as a ‘very knowledgeable professional able to simplify complex scenarios’, and Gabriela Ariel Irizar as ‘very capable’. The firm leverages its top-tier corporate practice to secure an impressive market share of merger-notification work, but the team also excels in cartel cases and anticompetitive investigations. On the transactional side, it advised CSL on the Argentine notification and associated merger review related to its $275m acquisition of Novartis’ flu vaccine business. The practice group also advised both Marriott and Starwood on the local competition aspects of their $13bn merger, which created the largest hotel group in the world. Among its contentious caseload, the team is defending a major international bank in the Competition Commission (CNDC)’s high-profile investigation into alleged collusion and abuse of dominance in the management of the VISA card system. Since the conclusion of research, del Rio has been made partner.

Allende & Brea acted on a string of headline merger-control cases over the past year and it also packs a punch in behavioural matters, particularly cartels. The ‘highly strategic’ department head Julián Peña is ‘great to deal with’ and is an acknowedged ‘leading light in the competition sphere’; he recently represented Dell in the local competition aspects of the $3bn sale of its IT services unit to NTT Data, and also acted for Siemens on its $6.6bn acquisition of Dresser-Rand. A strong year for investigations work also saw the group represent Indura in a case concerning an alleged cartel in the medical oxygen market. Senior associates Julieta González and Federico Rossi are also highly active in the area, although the latter is currently studying abroad. Other representative clients include Novartis, Daimler and Syngenta.

At Beccar Varela, Agustín Waisman heads a comprehensive practice that acts on the full range of competition matters including merger notifications, abuse of dominance cases, price fixing and antidumping. The group also calls on the expertise of an impressive second line of senior associates, namely Camila Corvalán and Mercedes Pando – both of whom have a strong focus on competition issues. In a recent high-profile piece of work, the team represented VISA before the CNDC in an investigation into alleged abuse of dominance. Among other headline merger cases, the team advised SAB Miller on the sale of its local business to Anheuser Busch (as part of a $280bn global transaction), and also acted for Deutsche Bank on the sale of its local business to Banco Comafi.

The ‘analytical and hands-on’, M & M Bomchil scores highly for its ability to advise on ‘diverse scenarios, rather than just being limited to antitrust issues’. Marcelo den Toom is a ‘great attorney in his field’ and heads a prominent practice that acts on a steady stream of merger filings, investigations and compliance matters. Notable highlights include advising Maersk on its acquisition of Hamburg-Süd; representing AT&T in its merger with Time Warner; and advising Viacom in its acquisition of Telefe, the largest broadcaster in Argentina. On the behavioural side, the team represented Banco Credicoop in the VISA card system investigation. The team has also recently undertaken work for Boehringer Ingelheim, Carrefour and Nestlé.

Under the leadership of Luis Barry, Pérez Alati, Grondona, Benites, Arntsen & Martínez De Hoz, Jr acts for an enviable mix of domestic, regional and multinational clients on competition and antitrust matters. Merger filings, competition litigation and investigations are all areas of activity, and the team regularly acts for clients in the telecoms, life sciences, technology, agribusiness and automotive industries. In a recent landmark case, the practice successfully represented BRF in seeking to overturn a request to notify its acquisition of certain trade marks from Molinos Río de la Plata, which constituted the first court ruling stating that the acquisition of trade marks should not trigger a filing. It also advised Cerberus Group on the merger-notification aspects of its acquisition of Reydel Argentina.

Both ‘knowledgeable and fair’, Baker McKenzie utilises the firm’s extensive global network to bring to bear strong experience in transnational mergers. It also advises on compliance matters, including antitrust training and audits, as well as investigations. Group head Esteban Rópolo has ‘strong expertise’ and advised Bolsa de Comercio de Rosario on its acquisition of Sistemas Esco. He also provides ongoing antitrust compliance advice to BASF Argentina.

The ‘superb boutiqueBouzat, Rosenkrantz & Asociados secures wide acclaim for the reputation of firm founder and ‘market leader’ Gabriel Bouzat, who is particularly valued for his experience as a former president of the CNDC. Virginia del Águila co-heads the competition practice and is also recommended. Merger filings, market investigations and class actions are all significant sources of work.

Satisfied clients of Bruchou, Fernández Madero & Lombardi point to its ‘excellent service delivery’ and ‘pragmatic advice’ as differentiating it from its peers. Traditionally better known for its transactional capability (and it filed seven new merger-control cases over the past year), the team also houses an increasingly prominent behavioural practice which is currently involved in 13 anticompetitive investigations. Among its recent filings cases, Estanislao Olmos advised Citibank on the sale of certain assets to Santander Río. Aixa Sureda is also a key contact.

Estudio O'Farrell’s group, led by public law and economic regulation partner Agustín Siboldi, ‘delivers work in a timely fashion and according to quality requirements’. Recent highlights include advising YPF on the competition aspects of its acquisition of a controlling shareholding of Apache’s assets in Argentina. The team is also advising Axion Energy on several contentious competition matters. Other representative clients include Farmacity, Ford Argentina and I Squared Capital.

Tanoira Cassagne Abogados maintains a solid reputation for antitrust matters under the leadership of preeminent market figure Bernardo Cassagne. Investigations are a particular area of specialism, but the team also advises on merger control and compliance issues. Maximiliano Krause is also recommended.

The broad practice at Wiener Soto Caparrós routinely handles merger clearance cases, investigations, antitrust compliance issues and litigation. Name partner and group head Mariela del Carmen Caparrós recently assisted Coca-Cola Andina on designing its compliance training programme. The team has also recently undertaken work for Fonterra Co-operative Group and NSK Global.
