Diego Pérez-Ordoñez > Pérez Bustamante & Ponce > Guayaquil, Ecuador > Lawyer Profile

Pérez Bustamante & Ponce fields a ‘team of true specialists‘ who ‘provides pragmatic, quick and clear advice‘ on the gamut of antitrust matters. The group is proficient in proceedings before the Ecuadorian Competition Authority and judicial courts, and often handles matters concerning abuse of dominance, cartels, state aid, merger control and unfair competition. Practice head Diego Pérez-Ordoñez possesses a wealth of experience in transactional and conduct mandates. These are also key areas of activity for practice director Mario Navarrete-Serrano, who demonstrates further strength in competition litigation. Since publication, Navarrete has been raised to the partnership – effective as of Janaury 2025.

Pérez Bustamante & Ponce is home to a ‘highly trained‘ corporate and M&A practice ‘with the business knowledge necessary to advise effectively‘ on multijurisdictional work, including complex deals that utilise the skills and participation of several of the firm’s teams – including labour, tax, antitrust and compliance. Diego Pérez-Ordoñez, who leads the M&A and antitrust practices, has a strong track record in landmark transactions in Ecuador. Juan Manuel Marchán-Maldonado advises both sellers and buyers on public and private M&A, joint ventures and asset dispositions across the retail, food and beverage, telecoms, energy and manufacturing sectors, among others.

Pedro Manuel Pérez joined from Carmigniani Pérez Abogados in 2023. At associate level, seniors David Carrera (whose corporate and transactional practice also has a restructuring aspect), and Carlos Dassum (who has particular expertise in the food & beverages, consumer and retail sectors) are the key names to note. Since publication, both Carrera and Dassum have been promoted to practice director level – effective as of February 2025.
