Oscar TrellesCuatrecasas

With the arrival of Diego Carrión in July 2022, Cuatrecasas continues its ascendancy in the Peruvian market and has been very active in M&A transactions in a relatively slow market. The practice offers wide-ranging corporate expertise, which encompasses M&A, distressed M&A, joint ventures, due diligence on deals and restructurings. Carrión, who joined from Hernández & Cía, now co-heads the team alongside Oscar Trelles and brings experience in domestic and international M&A transactions, as well as securities matters and financing arrangements. Managing partner Trelles stands out in cross-border M&A and private equity transactions. Kiomi Osorio is a key member of the team, who was promoted to partner in April 2022 and handles corporate and financial transactions, and advises on financial regulation.

Latin America: International firms > Corporate and M&A

Cuatrecasas is a significant player in Latin America thanks to its offices in Peru, Colombia, Mexico and Chile. Alongside its growing teams in these jurisdictions it has a substantial group of Latin America-facing practitioners in Iberia and New York. It is among the most prolific advisers on Latin America transactions, excluding Brazil. Along with a range of local transactions, the firm has extensive experience in cross-border deals, including private equity investments and exits. In January 2023, the firm absorbed Mexican four-partner firm Rico, Robles, Libenson, S.Cl into its local Mexico office and wider Latin America team – which  remains best known for operations in the energy and infrastructure, healthcare and retail sectors. Alfonso Ugarte transferred from Santiago to New York in 2022 to head the Latin America M&A, finance and special situations practice in North America. He joined an established Latin America-facing M&A team there, including Antonio Baena and Diego Pérez-Yarza; Baena recently advised Patria on the sale of Odata, the local company that operates a network of data centres in Latin America. Alfonso Reina led the launch of the Bogota office before returning to Madrid where he continues to have a strong focus on cross-border M&A in Colombia. Peru-based Oscar Trelles is head of the Latin America M&A and private equity practice and has a fine record in cross-border transactions, including intra-regional deals. Chile’s Roberto Guerrero V, Colombia-based Juan Felipe Vera and Santiago Ferrer in Mexico City are also key partners.
