The competition team at Pérez Bustamante & Ponce is highly visible in a range of competition and antitrust issues, regularly acting for both leading local companies and multinationals operating in Ecuador. The group regularly advises multinational clients on pre-merger assessments, merger control filings and competition-related regulatory matters arising from corporate transactions, with notable expertise in the automotive, retail, and banking sectors. The team also represent clients in unfair competition, gun-jumping, and unfair pricing disputes. The practice is directed by Diego Pérez Ordóñez, whose strong corporate background underpins his expertise in antitrust and merger control matters. Key contact Mario Navarrete handles the range of related matters, including preventative competition advice and administrative litigation. Competition and antitrust-focused senior associate Andrés Rubio supports on advisory and contentious mandates alike.
