Re.: Relevant Matter

Dear Sirs,

We are writing to inform you that Mr. Gabriel Blasi, who currently serves as Chief Financial Officer (CFO) of TELECOM ARGENTINA S.A.

Mr. Blasi concludes his extensive professional career having maintained an excellent working relationship with Telecom Argentina and having far exceeded the objectives entrusted to him.

We would like to thank Gabriel and the team he leads for their significant contribution and professionalism throughout the years, which have helped Telecom Argentina consolidate its position as an industry leader in a highly challenging environment.

During the transition period until his effective departure, the Company will activate the necessary succession plans to ensure continuity and quality in management.

Sincerely,
