Publication of new filing fees for the analysis and processing of notification of concentrations
Today (December 19, 2025), the Official communication by which the fees for the services provided by the National Antitrust Commission (the “Official Communication”), approved by the Board of Commissioners of the National Antitrust Commission (the “CNA”), was published in the Official Gazette of the Federation (“DOF”). The Official Communication establishes a new fee schedule applicable to various services provided by the CNA, including, most notably, for the analysis of notification of concentrations.
The filing fees for a notification of concentration ranges from MXN$882,158.00 (approx. USD$49,008.78) and could be as high as MXN$6,015,098.00 (approx. USD$)2.11) plus applicable VAT (currently 16%), which represents a substantial increase over the amounts that were previously paid.
The Official Communication entered into force upon its publication in the DOF; that is, today.
The adoption of this new tariff scheme is intended to increase CNA’s economic capacity, strengthen its management autonomy and seek to gradually reduce its dependence on federal budgetary resources. The Official Communication introduces a staggered tariff mechanism that is determined based on the Estimated Maximum Value of the transaction in Mexico (“VME”). Such value must be calculated and justified by the notifying parties under oath in the corresponding notification of concentration, taking as reference the highest value among the possible options available (e.g., amount effectively paid, value of assets effectively acquired, capital stock, among others).
Consequences are also established in case of underestimation of the value of the transaction, including the payment of differences, updates and surcharges, without prejudice to the penalties that may be applicable for false statements.
With the entry into force of the Official Communication, parties participating in transactions subject to mandatory premerger filings must consider, from the initial stages of structuring the transaction, the economic cost associated with the notification as an additional relevant element in the analysis of the transaction, as well as the need to make a careful and duly documented estimate of the EMV, given its direct impact on the applicable tariff.
