Argentina: National Antitrust Tribunal adopted update of adjustable unit values for merger control thresholds and antitrust fines in Argentina (Resolution No. 6/2026)

On 14 January 2026, the National Antitrust Tribunal adopted Resolution No. 6/2026 updating the value of the Adjustable Unit used for thresholds and fines under the Antitrust Law No. 27.442. In accordance with Article 85 of the Law, the Resolution updates the unit of account by reference to the annual variation of the Consumer Price Index for 2025. With effect from 19 January 2026, the value of the Adjustable Unit is fixed at ARS 1'450.05. As a result, the mandatory merger notification threshold is set at ARS 145'005'000'000 for transactions in which the aggregate turnover generated in Argentina by the parties exceeds 100'000'000 Adjustable Units. The de minimis exemption applies where the local assets of the target and the local transaction value each do not exceed 20'000'000 Adjustable Units, equivalent to ARS 29'001'000'000. Finally, the Resolution also updates the maximum fine for anticompetitive conduct to 200'000'000 Adjustable Units, or ARS 290'010'000'000, where turnover-based or benefit-based calculation methods are not applicable.
