Insights

LatAm telecom and regulation analyst

Telecom Argentina’s mobile acquisition moves forward with antitrust conditions.

The resolution confirms that the acquisition of exclusive control of Telefónica Móviles Argentina S.A. may proceed only if Telecom Argentina complies with a defined Remedy in Annex I, under Law No. 27,442 on economic concentration.

The decision signals regulatory acceptance of the transaction structure but with safeguards to address competition concerns. The specific obligations, once published by the National Authority for the Defense of Competition, will clarify how the company must adapt its operations or assets in Argentina.

Investors will be able to assess practical impact after Annex I is disclosed on the authority’s website, as that document will detail the Remedy that conditions completion and future conduct under the antitrust framework.
