OPINION ON THE PROPOSAL FOR BOARD OF DIRECTORS’ FEES FOR FISCAL YEAR 2025 AND ADVANCE FEE PAYMENTS TO DIRECTORS SERVING IN FISCAL YEAR 2026

The proposal submitted by the Board is to allocate to the Directors of TELECOM ARGENTINA S.A. who served in fiscal year 2025 (from January 1, 2025, to December 31, 2025), a total compensation of ARS 6,822,234,989.00, for all their duties, proposing that the General and Extraordinary Meeting delegate authority to the Board to distribute that amount among its members.

After exchanging ideas, the Audit Committee UNANIMOUSLY approves the amount of fees to be allocated to the abovementioned Directors of TELECOM ARGENTINA S.A. To that end, the Audit Committee has taken into consideration the following criteria to support such approval:

Each of the roles that have been performed by the members on the Board and the different Committees;

The responsibilities assigned and assumed, and the representation of the Company and its subsidiaries in the country and abroad;

The specific dedication to their functions as part of the Governing Body, and the value added to the business for the technical tasks performed during the year;

The provisions of article 261 of the General Corporations Law No. 19,550, and the compensatory nature of the functions assigned, as well as the provisions of CNV Regulations Chapter III Title II;

The experience of Board members in their roles as well as the track record, professional experience and reputation of Directors who will receive said fees;

The roles of Chairman and Vice-Chairman during the year under review, and the technical and administrative tasks fulfilled;

The added value of additional functions carried out by some Members of the Board on several committees (Executive Committee, Audit Committee), requiring a specific professional profile, spending many hours of work, and involving tasks of high responsibility;

The exclusive service of the Directors who are part of the Audit Committee, who do not participate in other Audit Committees in the market;

The Company’s business volume, and strategic decisions made by this body and the challenges associated with the function;

The proportionality, coherence and correlation of the proposal to be made to the General and Extraordinary Meeting with those submitted in previous fiscal years, considering the global context and the high adaptability to new situations and permanent challenges faced by the market where the Company operates;

The market behavior of publicly traded companies that are listed both on Argentine and US Stock Exchanges.

Therefore, based on the above, the Audit Committee UNANIMOUSLY resolves:

To approve said amount, in accordance with the tasks performed, the general context, and the fact that said amount is reasonable and adequate in terms of market conditions for similar companies, and does not involve any infringement of any legal, regulatory, or statutory provisions applicable to the Company.

To approve the proposal to empower the Board to make advance payments for fees to the Directors that will serve during the 2026 fiscal year (contingent upon the Shareholders' Meeting decision that considers the documentation for fiscal year 2026).

To delegate to the Chairman the communication of this resolution to the Board of Directors, as well as the signing of the pertinent documentation.

II.

OPINION ON THE PROPOSAL FOR INDEPENDENT AUDITORS’ FEES FOR FISCAL YEAR 2025

The Audit Committee considers the proposal to pay Price Waterhouse & Co. S.R.L. (“PwC”) for its services as External Auditors of the Financial Statements of TELECOM ARGENTINA S.A. for fiscal year 2025 the sum of ARS 1,735,224,000.00 (which does not include VAT), broken down into ARS 1,198,104,000.00 for financial statements audit tasks, and ARS 537,120,000.00 for audit tasks related to the certification under Section 404 of the Sarbanes Oxley Act.

After an analysis by its members, the Audit Committee considers that the proposed fees are reasonably adequate for the magnitude, importance and quality of the task carried out and within the range of fees approved by other listed companies with similar characteristics to TELECOM ARGENTINA S.A.

To reach this conclusion, the Audit Committee has considered the complexity of the task, and the specialization required to perform the audit activities developed by the Independent Auditors in relation to the certification of Section 404 of the Sarbanes Oxley Act. Therefore, the Audit Committee unanimously concludes that the fees that the Board of Directors will propose to the Meeting as remuneration for the performance of such activities are equally reasonable, and UNANIMOUSLY approves said proposal.

III.

The Audit Committee, pursuant to the provisions of the CNV regulations (informed opinion required by Articles 25 and 28 of Section VI of Chapter III of Title II of Regulations N.T. 2013 and amendments), has assessed the background and performance of Price Waterhouse & Co. S.R.L. (“PwC”), which is also the current provider of independent auditing services of TELECOM ARGENTINA S.A.

In this regard, the review of PwC’s profile carried out by the Audit Committee was based on:

The composition of its work teams, which demonstrate a deep understanding of its business systems and processes, particularly the process of generating financial information, both at the audit and support team levels, nationally and internationally.

The knowledge of the firm and related companies.

The assessment of its performance, based on the Audit Committee’s activities of annual oversight and evaluation of Independent Auditors, whose essential objective is to achieve reliability in the financial information that the Company provides to control entities, investors, and markets.

The profile of PwC as a firm of local and international recognized prestige, with a vast and outstanding professional record, and with procedures that meet stringent levels of quality and independence at its audited companies.

The firm’s sound knowledge of the business of TELECOM ARGENTINA S.A., and of its administrative systems and control structure.

Therefore, the Audit Committee, based on the background of the proposed firm, its performance in previous years and the abovementioned considerations, UNANIMOUSLY resolves to submit to the Board of Directors a favorable opinion on the proposal to appoint PwC as Independent External Auditors for fiscal year 2026.
