Ecuador > Corporate and M&A

Full-service market powerhouse Pérez Bustamante & Ponce fields a 40 strong corporate practice (including 15 corporate tax advisers) and can comfortably undertake sizeable transactions and mandates. Recent highlights saw the team advise Procesadora Nacional de Alimentos on the purchase and lease of all poultry-company Avesca Avicola Ecuatoriana’s productive assets – a transaction that also involved employment matters, service agreements, trade mark licensing and a purchase option agreement as well as the contractual framework to implement the deal. Handling this matter and leading the wider corporate practice is Diego Pérez, who has profound experience in transactions involving both domestic and foreign companies. Fellow partner Juan Manuel Marchán heads up the firm’s growing Guayaquil presence and frequently handles M&A work related to infrastructure and projects. On the corporate side, the team has benefitted from Esteban Ortiz Mena’s July-2021 return (as a partner) from the Superintendencia de Compañias, Valor y Seguros; his practice focuses on company law, corporate affairs and corporate governance matters. At associate level, senior Andrés Brown is an up-and-coming figure of note; admitted to practice in Spain, New York and Ecuador, he regularly advises clients on local and international transactions in relation to acquisitions, joint ventures, asset purchases and share purchase agreements.
