Merger Control in Mexico: Regulatory Framework and Competition Law Reforms

October, 2026

Von Wobeser y Sierra lawyers examine changes to Mexico’s merger control regime, notification requirements and clearance procedures in a contribution to The Legal 500.

Our partners Fernando Carreño, Sergio López and Michel Llorens, together with associates Andoni Garza and María García, authored the Mexico chapter on Merger Control for The Legal 500 Country Comparative Guides 2026.

The publication examines the legal and regulatory framework governing merger control in Mexico, with particular emphasis on the changes introduced by the reform of the Federal Economic Competition Law and the establishment of the National Antimonopoly Commission (NAC).

Key topics include lower mandatory notification thresholds, revised statutory review periods, pre-merger clearance requirements and the consequences of completing transactions without complying with applicable regulations.

The chapter also addresses substantive merger assessment criteria, review procedures, potential remedies and recent trends in competition law enforcement.

The analysis provides a reference for businesses involved in mergers and acquisitions in Mexico, particularly regarding transaction planning and the identification of regulatory risks.
