Re.: Report on decision of Federal Court of Appeals of Tucuman in the case entitled “Asociación de Consumidores del NOA versus Telecom Personal S.A. Re. Consumers´ Defense Law” Docket: 15065/2016

Dear Sirs,

I am writing to you in my capacity as Attorney-in-Fact of Telecom Argentina S.A. (“Telecom Argentina” or the “Company”), following up on the material event published on December 2nd, 2025.

We hereby inform you that the Company has been notified of the ruling issued by the Federal Court of Appeals of Tucumán that partially granted the appeal filed by the Asociación de Consumidores del NOA against the sentence of Federal Court No. 1 of Tucumán, which had ruled against the action brought by said Association.

In this respect, the Federal Court of Appeals of Tucumán confirmed the trial court’s judgment insofar as it rejected the compensatory liability attributed to Telecom Argentina for the service outage that occurred on March 3, 2015, and reversed it solely insofar as it rejected the proportional reimbursement to users of the price corresponding to the service not provided during the aforementioned outage.

Sincerely,

	Telecom Argentina S.A.
