Telecom Argentina SA
One of Argentina's biggest telecoms, this company offers mobile phone service under the Personal brand, home internet, cable TV through its Flow platform, and a digital wallet called Personal Pay, serving homes and businesses across several South American countries. It was born in 1990 when the government split the state-run phone monopoly ENTel in two, and it took the northern half of the country. In 2018 it merged with cable operator Cablevisión. Fun fact: its Personal mobile brand debuted in 1995, chosen because a cell phone, unlike a landline, belonged to the individual rather than a household.

Summarized below are the financial instruments we held as of December 31, 2025, that are sensitive to changes in foreign exchange rates, market prices and interest rate, if any. As a matter of policy, we may enter into forward exchange contracts, foreign currency swaps or other derivatives to manage the exposure attributed to foreign exchange rate and interest rate fluctuations associated with the principal amount of our liabilities in foreign currencies. We use these instruments to reduce risk by creating offsetting market exposures. The instruments we hold are not held for financial trading purposes. No foreign exchange forward or other derivatives for speculative purposes were outstanding during the reporting periods covered by this Annual Report. We do not have any other material market risk exposure. a) Foreign Exchange Rate Risk Foreign exchange exposure arises from our funding operations, and, to a lesser extent, our capital expenditures and expenses denominated in foreign currencies. The Peso/U.S. dollar exchange rate is determined by a free market with certain controls. See “Item 10—Additional Information—Foreign Investment and Exchange Controls in Argentina.” Our results of operations are sensitive to changes in the Peso/dollar exchange rates because our primary assets are in Argentina and most of our revenues are denominated in Pesos (our functional currency) while some parts of our liabilities are denominated in foreign currencies. Additionally, the Company has cash and cash equivalents, and investments denominated in U.S. dollars and other currencies that are also sensitive to changes in Peso/U.S. dollar exchange rates and contribute to reduce the exposure to commercial and financial obligations in foreign currency. The devaluation of the Argentine Peso over the last few years, which was 41.0% in 2025, has had and continues to have a negative impact on the payment and revaluation of debts denominated in foreign currency, and any further devaluation may adversely affect our financial situation and operating results. Also, the devaluation rate was higher than the inflation rate of the Argentine Peso, which amounted to 31.5%. Fluctuations in exchange rates may adversely affect the value, translated or converted into U.S. dollars, of our net assets, earnings and any declared dividends. We cannot give any assurance that any future movements in the exchange rate of the Peso against the U.S. dollar and other foreign currencies will not adversely affect our results of operations, financial condition and cash flows. However, we believe that a significant depreciation in the Peso against major foreign currencies may have a material adverse impact on our capital expenditure program and in our operating expenses denominated in foreign currencies. b) Interest Rate Risk Within its structure of borrowings, Telecom has bank overdrafts denominated in Argentine Pesos accruing interest at rates that are reset at maturity, notes and other financial entities’ loans denominated in Argentine Pesos, U.S. dollar, RMB and Paraguayan Guaraníes that bear interest at fixed and variable rates, so it is exposed to the risk of interest rate fluctuation, mainly through the fluctuation of the SOFR. c) Price Risk The Company’s investments in financial assets at fair value through profit or loss are subject to the risk of changes in market prices arising from fluctuations in the future value of these assets. The Company conducts an ongoing monitoring of the evolution of these assets’ prices. See Note 27 to our Consolidated Financial Statements for a description of financial risk management.

Capitalization and Indebtedness Not applicable. Reasons for the Offer and Use of Proceeds Not applicable. Risk Factors This section is intended to be a summary of more detailed discussions contained elsewhere in this Annual Report. The risks described below are not the only ones that we face. Additional risks that we do not presently consider material, or of which we are not currently aware, may also affect us.

Accordingly, our financial condition, results of operations and cash flows depend to a significant extent on economic and political conditions prevailing in Argentina and on the exchange rates between the Argentine Peso and foreign currencies. In the recent past, Argentina has experienced severe recessions, political crises, periods of high inflation and significant currency devaluation. The Argentine economy has been volatile over time, with years of economic growth and others with recession. Several factors have impacted negatively the Argentine economy in the recent past, and may continue to impact it in the future, including among others, inflation rates, exchange rates, commodity prices, level of BCRA reserves, public debt, tax pressures, trade and fiscal balances, government policy and the international and macroeconomic conditions. Those conditions could adversely affect our operations. Devaluation of the Argentine Peso and foreign exchange restrictions may adversely affect our results of operations, our capital expenditures and our ability to service our liabilities and pay dividends. Since we generate a substantial portion of our revenues in Argentine Pesos (our functional currency), any devaluation may negatively affect the U.S. dollar value of our earnings while increasing, in Peso terms, our expenses and capital expenditures denominated in foreign currency. The Argentine Peso has been subject to significant devaluation against the U.S. dollar in the past and may be subject to fluctuations in the future. The value of the Argentine Peso compared to other foreign currencies is dependent, among other factors, on the level of international reserves maintained by the BCRA, which have also shown significant fluctuations in recent years. The Argentine macroeconomic environment, in which we operate, has been affected by the continued devaluation of the Argentine Peso, which in turn has and could continue to have a direct impact on our financial and economic position. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 14 Table of Contents The value of the Argentine Peso has fluctuated significantly over time. In 2025, the Argentine Peso continued to depreciate against the U.S. dollar and other major foreign currencies. The Peso depreciated at a faster rate compared to the previous year, with a monthly depreciation of approximately 3.0%. According to Banco de la Nación Argentina, the Argentine Peso/dollar exchange rate stood at P$1,455 per US$1.00 as of December 31, 2025, evidencing an appreciation of the U.S. dollar against the Argentine Peso of approximately 41.0% from its value of P$1,032 per dollar on December 31, 2024 (compared to 27.7% and 356.3% in the years ended December 31, 2024 and 2023, respectively). If we analyze the behavior of the average exchange rate, during 2025 it stood at P$1,245.0 per dollar. Heightened restrictions to access the official FX Markets were imposed starting in 2020, and some exchange rates are only available to certain markets participants, or in the activities in which the currency is held. In addition, dealing with certain reference rates might directly affect the access of the Company to the Argentine Single and Free Exchange Market (“MULC” for its Spanish acronym). The requirements to access different exchange rates, as well as the actual exchange rate of each option, vary significantly from one another. During 2024, the Milei administration implemented policies aimed at modifying Argentina’s macroeconomic conditions, such as reducing the fiscal deficit, reforming the National State, privatizing public companies and rationalizing the current spending of the national administration. These measures and any future measures may generate volatility in the economic and financial conditions of Argentina. To address the issue of increasing commercial debt deriving from the additional restrictions on the payments of imports described above, under Milei’s administration, the BCRA has been offering U.S. dollar-denominated securities (BOPREAL, standing for Bond for the Reconstruction of a Free Argentina in Spanish), which can only be subscribed by importers with overdue debts for goods with customs registration and/or services actually rendered until December 12, 2023. BOPREALs may be used for easier access to foreign currency, whether through the collection of interest or principal upon maturity, or through the sale of the bonds in the secondary market in exchange for dollars paid abroad. Access to the MULC for the payment of imports pending as of December 12, 2023, is subject to the prior authorization of the BCRA. Additionally, importers of goods and services may not pay any overdue amounts on account of imports as of December 12, 2023, by any other means, except for dollars held abroad or dollars obtained through BOPREALS, without jeopardizing access to the official exchange market. Pursuant to current BCRA rules, importers will not be entitled to access the MULC for 90 days if they have conducted exchange transactions involving the sale/purchase of securities (other than BOPREALs) settled in dollars abroad. In this regard, between January and May 2024, the BCRA completed the Series 1, 2 and 3 BOPREAL auctions issuing their maximum amounts of US$5,000 million, US$2,000 million and US$3,000 million, respectively. In 2025, the BCRA launched Series 4 of BOPREAL bonds, with a maximum issuance amount of up to US$3,000 million, aimed at addressing outstanding foreign-currency obligations, including retained dividends, commercial and financial debt with related parties and inherited commercial debts. The first auction of Series 4 took place in June 2025, with additional tranches auctioned thereafter. We participated in the auctions of BOPREAL 1 and 2 Series during January and February 2024. The bonds allowed us to agree to a settlement of the existing commercial debt with our main suppliers, which we negotiated with each counterparty individually. On April 11, 2025, the Ministry of Economy and the BCRA announced the beginning of “Phase 3” of the economic program started on December 10, 2023. In this new phase, (i) the rate of the U.S. dollar in the FX Market may fluctuate within a moving band between P$1,000 and P$1,400, a limit to be increased at a rate of 1% per month; and (ii) the nominal anchor is reinforced, as the BCRA will continue to refrain from issuing Argentine pesos to finance the fiscal deficit or to remunerate its monetary liabilities, through a crawling peg mechanism. Separately, pursuant to Communication “A” 8226 dated April 11, 2025, the BCRA also lifted restrictions preventing individuals from accessing the FX Market to purchase U.S. dollars. The Communication also allows local companies to use the FX Market to distribute profits to foreign shareholders for financial years starting on or after January 1, 2025. Additionally, the BCRA eased restrictions on payment terms for foreign trade transactions. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 15 Table of Contents As part of “Phase 3” of the economic program, on April 16, 2025, the BCRA also issued Communication “A” 8230, easing restrictions for the payment of certain related parties’ cross border financings and the repatriation of direct investments made by foreign investors in companies (other than companies controlling local financial entities) and allowing foreign investors to repatriate payments received in Argentina on account of securities listed in local markets (whether such payments derive from payments of principal or interest under such securities or the proceeds from the sale of such securities); in each case subject to certain conditions. In addition, on December 15, 2025, the BCRA announced adjustments to the existing exchange rate framework. Effective January 1, 2026, the minimum and maximum exchange rate bands will be updated on a monthly basis in accordance with the most recent inflation data published by INDEC, replacing the prior crawling peg mechanism. The BCRA further indicated that the exchange rate will continue to operate under a floating regime within bands, with the objective of reducing the risk of extreme or abrupt exchange rate movements, while taking into account market liquidity conditions and trends in money demand. The measures imply changes in the conditions of access to the FX market to purchase U.S. dollars. The Company cannot guarantee the success of these measures or that such measures will be sustained over time. For further information, see “Item 10—Additional Information—Foreign Investment and Exchange Controls in Argentina—Specific provisions for inward remittances—External financial indebtedness.” The success of these measures is uncertain and any further depreciation of the Argentine Peso or our inability to acquire foreign currency could have a material adverse effect on our financial condition and results of operations. We cannot predict the effectiveness of these measures, nor whether, or to what extent, the value of the Argentine Peso may depreciate or appreciate against the U.S. dollar or other foreign currencies, nor our ability to meet our liabilities denominated in foreign currencies, or how these uncertainties will affect demand for the services we provide. Furthermore, no assurance can be given that, in the future, no additional currency or foreign exchange restrictions or controls will be imposed. Existing and future measures may negatively affect Argentina’s international competitiveness, discouraging foreign investments and lending by foreign investors or increasing foreign capital outflow which could have an adverse effect on economic activity in Argentina, and which, in turn, could adversely affect our business and results of operations. Depreciation of the Argentine Peso against major foreign currencies may have a material adverse effect on our financial condition and results of operations and also have an adverse impact on our capital expenditure program and increase the Argentine Peso amount of our trade payables and borrowings denominated in foreign currencies. As of December 31, 2025, P$5,436,854 million of our liabilities were denominated in foreign currencies. Despite that Telecom seeks to manage the risk of devaluation of the Argentine Peso, by entering from time to time into certain DFI agreements and futures contracts to hedge some of its exposure to foreign currency fluctuations, Telecom remains highly exposed to risks associated with the fluctuation of the Argentine Peso. In addition, the devaluation of the Argentine Peso and foreign exchange restrictions may affect compliance with our covenants. See “—Risks Relating to Telecom and its Operations—Restrictive covenants in Telecom’s outstanding indebtedness may restrict its ability to pursue its business strategies.” Any restrictions on transferring funds abroad imposed by the Argentine government could undermine our ability to pay dividends on our ADSs or make payments (of principal or interest) under our outstanding indebtedness in U.S. dollars, as well as to comply with any other obligation denominated in foreign currency. See “Item 10—Additional Information—Foreign Investment and Exchange Controls in Argentina.” Economic and political reforms in Argentina, and future policies of the Argentine government may affect the economy as well as the operations of the telecommunications industry. The Argentine government has historically exercised significant influence over the economy, and telecommunications companies have operated in a highly regulated environment. The Argentine government may promulgate numerous, far-reaching regulations affecting the economy and telecommunications companies, as shown by, the enactment of Decree No. 690/20 in August 2020, and the nationalization of the private pension and retirement system in 2008. For more information see “—The Argentine government may exercise greater intervention in private sector companies, including Telecom.” PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 16 Table of Contents Moreover, the long-term impact of these measures and any future measures taken by the Argentine government on the Argentine economy, as a whole and in the telecommunication sector remains uncertain. It is possible that such reforms could be disruptive to the economy and adversely affect the Argentine economy and the telecommunications industry, and consequently, our business, results of operations and financial condition. We are also unable to predict the measures that the Argentine government may adopt in the future, and how they will impact on the Argentine economy and our results of operations and financial condition. In the event of any economic, social or political crisis, companies operating in Argentina may face the risk of strikes, expropriation, nationalization, mandatory amendment of existing contracts, and changes in taxation policies including tax increases and retroactive tax claims. In addition, Argentine courts have sanctioned modifications on rules related to labor matters, requiring companies to assume greater responsibility for the assumption of costs and risks associated with sub-contracted labor and the calculation of salaries, severance payments and social security contributions. Since we operate in a context in which the governing law and applicable regulations change frequently, also as a result of changes in government administration, it is difficult to predict if and how our activities will be affected by such changes. On December 21, 2023, the Milei administration issued Decree of Necessity and Urgency (“DNU”) No. 70/2023, entitled “Bases para la Reconstrucción de la Economía Argentina” (Foundations for the reconstruction of the Argentine economy) establishing various initiatives for the deregulation of the economy and reduction of the size of the public administration and public expenses. Such decree remains mostly in effect. The decree includes a series of legal, institutional, tax, and criminal reforms affecting various sectors of the economy. Additionally, the decree declares a public emergency in economic, financial, fiscal, social security, defense, tariff, energy, health and social matters until December 31, 2025, extendable for two additional years, and delegates numerous legislative powers to the PEN for the duration of the public emergency. Pursuant to Decree No. 942/2025, issued in December 2025, the public health emergency originally declared under DNU No. 70/2023 was extended for an additional period, while the remaining emergency declarations expired on December 31, 2025, unless otherwise extended by applicable law or decree. This decree is subject to the subsequent legislative control established by Section 99, paragraph 3, of the Argentine Constitution and Law No. 26,122, which provides that the decree shall remain in force until it is rejected by both Houses of the Argentine Congress. Pursuant to Article 23 of Law No. 26,122, each house of the Argentine Congress must accept or reject the decree in its entirety—without introducing amendments, additions or deletions—by an absolute majority vote of the members present. On March 14, 2024, the Senate rejected the decree and was subsequently forwarded to the lower house. The decree will become ineffective only if the lower house rejects it by an absolute majority of the members present. As of the date of this Annual Report, the decree remains in effect, as the lower house has not yet issued a decision on its rejection. The review conducted by the Permanent Bicameral Commission —established under Law No. 26,122— does not limit Congress’ ordinary powers to repeal legislative measures issued by the Executive Branch, as provided in Article 25 of such law. A bill to amend Law No. 26,122 and reform the system of Congressional oversight of emergency, delegated and DNUs has received preliminary approval in Congress. If enacted, DNUs would remain in force only upon express approval by the Bicameral Commission and both chambers within mandatory time periods. As a result, the continued validity of DNU No. 70/2023 and any subsequent DNUs could be affected, potentially modifying the regulatory framework described herein. The Milei administration also submitted to the Argentine Congress a significant number of reforms through the omnibus bill, entitled “Bases y Puntos de Partida para la Libertad de los Argentinos” (Foundations and Starting Points for the Freedom of the Argentine People or “Ley de Bases”). After months of negotiation, on June 28, 2024, the bill finally passed, and the Ley de Bases was approved. On the same date, Congress also approved the measures related to the regularization of tax, customs, and fiscal obligations, in order to achieve voluntary payment obligations by taxpayers. If they join the regime, they will receive different benefits depending on their membership and the type of debt they have. The key points of the Ley Bases are the following: ● Emergency: Ley de Bases declared a public emergency on administrative, economic and energy matters and delegated legislative powers to the Executive Branch under Section 76, subject to reporting to Congress; PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 17 Table of Contents ● State Reform: The law establishes the bases for state reorganization to improve efficiency, reduce the size of the state and strengthen internal controls. It also provides for the total or partial privatization of selected state-owned companies and introduces reforms to administrative procedures, public employment and collective labor regulations; ● Incentive Regime for Large Investments: The law creates the “Régimen de Incentivos para Grandes Inversiones” (RIGI), a legal and regulatory framework to promote large scale investments in strategic sectors, providing incentives, legal certainty and protection of acquired rights; ● Concessions: The law authorizes the granting of public works and public service concessions to private or public entities, financed through tariffs, tolls or other forms of remunerations; ● Energy: The law introduces reforms to the hydrocarbons, natural gas and electricity regulatory frameworks, including the creation of a unified national gas and electricity regulatory authority and the empowerment of the Executive to adapt existing energy legislation; and ● Labor modernization: The law introduces modifications to key labor laws, repeals certain enhanced compensation regimes, redefines employer responsibility in registered employment relationships and limits claims derived from third-party labor arrangements, while further labor reforms remain under congressional discussion. Through Decree No. 585/2024, Milei created the Ministry of Deregulation and State Transformation, appointing Federico Sturzenegger as its head. The Ministry’s functions include deregulation and state reform, through the formulation and implementation of national policy; simplification and downsizing of the State to eliminate unnecessary tasks and promote private job creation and economic development, and increasing competitiveness by reducing bureaucratic burdens, and regulatory constraints. In line with these transformation policies, on October 21, 2024, the Executive branch announced the dissolution of the AFIP and its replacement through the creation of ARCA, which is under the purview of the Ministry of Economy. This measure was officially established through Decree No. 953/2024, which established that this new autonomous entity is AFIP’s legal successor and will maintain the responsibilities, powers, and functions assigned to the AFIP until the regulations regarding the powers, rights, and obligations, and the organic and functional structure of the new entity are published. Additionally, in 2024, the lower house ratified two presidential vetoes that nullified significant laws passed by Congress. In September 2024, President Javier Milei’s veto of the law proposing an increase in retirement benefits was upheld, and in October 2024, the veto of the University Financing Law, which had been passed on September 13, 2024 by both chambers, was also upheld. In both cases, the decisions became final, leaving the Congress with no possibility of insisting on the passing of the regulations for the remainder of the parliamentary year. On May 22, 2025 the Argentine Government announced the program “Reparación Histórica del Ahorro de los Argentinos,” which is intended to encourage the use of dollars that Argentine citizens have saved and not channelled through the Argentine financial system. One of the main decisions announced by the PEN entailed the repeal of several informative regimes requiring reports on purchases with credit and debit cards and virtual wallets, the purchase and sale of used vehicles, real estate sales and the use of public services such as electricity, water, gas and telephony. After this announcement was made, on June 5, 2025, the PEN proposed to the Argentine Congress the enactment of the “Principio de Inocencia Fiscal” bill, with a view to allowing to any individual seeking to bring U.S. dollars held outside the Argentine financial system into the formal economy. On December 26, 2025, the Argentine Congress enacted Law No. 27,799, published in the Official Gazette on January 2, 2026, that introduces significant amendments to the Criminal Tax Regime, Tax Prescription and fine amounts, and an optional and simplified tax regime for income tax filling for Individual residents. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 18 Table of Contents On September 4, 2025, the Argentine Senate approved a bill seeking to establish additional limits on the use of DNUs by the PEN. The proposed legislation would require that each DNU be limited to a single matter and that its validity be subject to ratification by an absolute majority of both chambers within 90 calendar days; if such ratification is not obtained, the decrees would be rendered ineffective. The bill was subsequently debated in the lower house. However, a key article establishing the deadlines and requirements for ratification failed to achieve sufficient consensus during the specific debate, preventing the initiative from becoming law and requiring its return to the Argentine Senate. Although the specific impact of these legislative processes remains uncertain, no assurance can be given that they will not affect the overall operating context of the market. We cannot assure you that future economic, regulatory, social and political developments in Argentina will not adversely affect our business, financial condition or results of operations, or cause a decrease in the market value of our securities. Inflation is high and could accelerate further, causing adverse effects on the economy and negatively impacting Telecom’s margins and/or ratios. Argentina has a hyperinflationary economy, and there is no assurance that inflation rates will not rise further in the future. Furthermore, the INDEC has experienced periods of political intervention that raised serious concerns about the reliability of its published data. As a result, at the end of February 2024, a London Court of Arbitration ordered Argentina to provide US$337 million in bonds to proceed with a lawsuit regarding the calculation method used for a series of debt bonds known as “GDP coupons.” The claim, initiated by a number of investment funds, alleges that the former administration led by Cristina Kirchner, with Axel Kicillof as Minister of Economy, changed the base year for calculating economic growth in 2013 to avoid triggering a GDP coupon payment. This coupon, established in Argentina’s 2005 debt restructuring, was designed to incentivize creditors to participate in a swap by promising additional payments for each year in which Argentina’s GDP grew by more than 3%. On October 15, 2024, the Supreme Court of the United Kingdom dismissed Argentina’s appeal against the first-instance ruling. The Court of Appeal in London had previously denied Argentina leave to appeal. As a result, Argentina has no further legal recourse and is ordered to pay €1,330 million (US$1,443 million), plus applicable interest, in damages and indemnities related to the “GDP-coupons” case in the United Kingdom. Future political intervention in the INDEC could jeopardize the agency’s autonomy and therefore affect the reliability of its published statistics. In early 2025, holders of these securities urged Argentina to engage in discussions regarding the execution and timing of payment of the judgment, following developments in Argentina’s macroeconomic and financial framework. In addition, certain guarantees in an aggregate amount of approximately €313 million were executed as part of enforcement actions related to the UK judgment. In addition, during last three years, various factors in the international economic and financial context, such as the military conflict between Russia and Ukraine and between Israel and Hamas, and the turbulence in international financial markets caused by rising inflation, particularly in the United States and Europe, had a negative impact on emerging economies such as Argentina. See “—Adverse global economic and geopolitical developments may negatively impact the Argentine economy and, in turn, our business, financial condition, results of operations, and cash flows.” For example, inflation in Argentina raised significantly during 2023, reaching the highest monthly inflation of over 25% in December 2023, when the Milei administration took office. With the Milei administration, inflation experienced a notable decrease, attributed to the policies of fiscal adjustment, control of monetary issuance and economic opening implemented. The CPI variation was 31.5% in 2025, 117.8% in 2024 and 211.4% in 2023. Monthly inflation for January 2026 was 2.9%. Efforts made by the Argentine government to contain and reduce inflation are expected to, as of the date of this Annual Report, achieve the desired results, as inflation is currently declining. If the value of the Argentine Peso cannot be stabilized through fiscal and monetary policies, an increase in inflation rates could be expected. For additional information, see Note 1.d) to our Consolidated Financial Statements. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 19 Table of Contents A high inflation rate, or a hyperinflationary process, would affect Argentina’s external competitiveness by diluting the effects of the depreciation of the Argentine Peso, negatively impacting employment and the level of economic activity, and undermining confidence in the Argentine banking system, which may further limit the availability of domestic and international credit for companies. At the same time, a portion of Argentina’s debt continues to be adjusted by the CER, a monetary index, which is strongly correlated with inflation. Therefore, any significant increase in inflation would drive an increase in Argentina’s external debt and, consequently, in Argentina’s financial obligations, which could exacerbate strains on the Argentine economy. A continued inflationary environment could undermine our operating results. Because the majority of our revenues are denominated in Argentine Pesos, any further increase in the inflation rate not accompanied by a parallel increase in our prices would decrease our revenues in real terms and adversely affect our results of operations. Further, higher inflation rates generally lead to a reduction in the purchasing power, thus increasing the likelihood of a lower level of demand for our fixed and mobile telecommunications, cable television and internet services in Argentina. The Argentine government may exercise greater intervention in private sector companies, including Telecom. The Argentine government exercised in the past, and may exercise in the future, decisions to intervene in private companies in financial distress. We cannot predict whether the current administration or future administrations will take similar or further measures, including nationalization, expropriation and/or increased Argentine governmental intervention in companies. Government intervention in the industries in which we operate could create uncertainties for investors in public companies in Argentina, including Telecom Argentina, as well as have a material adverse effect on our business, financial condition, and results of operations. See “—Economic and political reforms in Argentina, and future policies of the Argentine government may affect the economy as well as the operations of the telecommunications industry.” A deterioration of domestic conditions may result in a return to economic contraction, which could adversely affect our operations. The Argentine economy has faced significant volatility in recent years, characterized by periods of slow or declining economic growth, high and fluctuating inflation rates, and depreciation of the Argentine Peso. Following a period of recovery after the sharp economic downturn in 2020, Argentina’s economy contracted again in 2023 and 2024 before returning growth in 2025. During 2025, Argentina’s economy underwent broad macroeconomic adjustment measures while ongoing constraints on the country’s foreign exchange reserves continued to exert pressure on the value of the Peso. Substantially all our operations, properties and customers are in Argentina, and, as a result, our business is largely dependent upon the economic and legal conditions prevailing in Argentina. Global financial instability, pandemics, and other health-related crises (as well as government responses thereto), the armed conflicts between Russia and Ukraine and generally in the Middle East (such as the conflict between Israel and Hamas), the current situation in Venezuela, or global economic conditions, any future increases in the interest rate of the United States and other developed countries, changes in economic or political conditions in Latin America and any other global economic events may impact the Argentine economy and prevent Argentina from getting back on track to growth or could aggravate the current recession with consequences in trade and fiscal balances and in the unemployment rate. Argentina’s economy may be negatively affected in the future by several domestic factors, including an appreciation of the real exchange rate that could undermine its competitiveness and further worsen the trade balance. Combined with capital outflows, this could reduce levels of consumption and investment and result in greater exchange rate pressure. Abrupt changes in monetary and fiscal policies or the foreign exchange framework could rapidly affect local economic output, while insufficient investment in certain economic sectors could reduce long-term growth. Access to international financial markets could be limited. An increase in public spending without a corresponding increase in public revenues could affect Argentina’s fiscal results and generate uncertainties that could constrain economic growth. If economic conditions in Argentina were to further deteriorate, they could have an adverse effect on our results of operations, financial condition, and cash flows. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 20 Table of Contents Adverse global economic and geopolitical developments may negatively impact the Argentine economy and, in turn, our business, financial condition, results of operations, and cash flows. The global macroeconomic environment is facing considerable challenges. There is substantial uncertainty over the long-term effects of the monetary and fiscal policies adopted by the central banks and financial authorities of some of the world’s leading economies, including the United States, Europe and China. The United States Federal Reserve (“Fed”) lowered interest rates in September, November and December 2024, which were the first reductions in four years, and continued cutting rates in September and December 2025. Some members of the Federal Open Market Committee have indicated that these reductions reflect a gradual approach to normalizing monetary policy, allowing for an evaluation of the policy’s restrictive impact as the U.S. economy progresses. However, the potential impact of these and other future Fed interest rate adjustments on the Argentine economy and our operations remains uncertain. Some of these monetary measures negatively impacted financial markets during 2022 and 2023. United States has remained one of Argentina’s main trading partners.’ Under the Trump Administration, the trade relationship between the two countries could have a dual effect: while it could promote Argentine soybean exports, potential protectionism could negatively affect other economic sectors in Argentina. On November 13, 2025, the United States and Argentina announced their intention to enter into a bilateral framework agreement to deepen bilateral trade and investment cooperation, encompassing the elimination of non-tariff barriers, regulatory harmonization, intellectual property, agricultural market access, labor and environmental standards, economic security, digital trade and transparency in state-owned enterprises’ operations. Certain measures announced by the Trump administration have nonetheless generated concern in international trade due to the potential renegotiation of agreements and the implementation of tariffs and defensive measures. There is also uncertainty as to how the trade relationship between Mercosur member States will unfold, particularly between Argentina and Brazil. We cannot predict the effect on the Argentine economy and our operations if trade disputes arise between Argentina and Brazil, or if either country were to exit the Mercosur. Since October 2023, an armed conflict between Israel and Hamas-led Palestinian militant groups has taken place primarily in and around the Gaza Strip, with hostilities extending to the West Bank, the Israel-Lebanon border and Iran. In October 2025, Israel and Hamas reached a ceasefire agreement as part of a broader international peace plan, however, the durability of the ceasefire remains uncertain, with claims of breaches having been made. The United Nations has reinstated sanctions on Iran over its nuclear program, and the United States has intensified a pressure campaign including sanctions targeting entities linked to the financing of Hamas and Hezbollah. In late February and early March 2026, a major regional conflict erupted after the United States and Israel launched large-scale airstrikes against Iran, targeting military, government, and nuclear-related infrastructure and killing Iran’s Supreme Leader, Ayatollah Ali Khamenei; Iran responded with widespread missile and drone attacks against Israel, U.S. bases, and several Gulf countries, drawing in regional actors and disrupting airspace, energy infrastructure, and civilian life across the Middle East, while the fighting caused significant casualties, displacement, market volatility, and intense international diplomatic efforts aimed at preventing further escalation into a broader war. These developments have increased uncertainty in international markets and could contribute to volatility in global financial conditions. The Russia-Ukraine sanctions could adversely affect the global economy and financial markets and thus could affect our business, financial condition, or results of operations. The extent and duration of the military conflict, sanctions and resulting market disruptions are impossible to predict, but could be substantial. Any such disruptions caused by Russian military action or resulting sanctions may magnify the impact of other risks described in this Annual Report and may result in compliance and operational challenges for the Company. We maintain telecommunications agreements with certain third-party international carriers that may deliver traffic between the Company’s networks, Russia and Ukraine, potentially including certain sanctioned territories within Ukraine. Although U.S. sanctions authorize the receipt or transmission of telecommunications with such sanctioned territories, to the extent that any activities involving those international carriers are outside the scope of such authorization, or sanctions relating to Russia and Ukraine are expanded, such activity may potentially result in regulatory or enforcement actions against the Company. In January 2025, oil prices rose by approximately 2% following the expectation that the expansion of U.S. sanctions against Russia which are expected to impact the export of Russian crude oil, could increase transportation costs and oil prices. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 21 Table of Contents In January 2026, the United States launched air strikes against Venezuela, captured former President Nicolas Maduro and announced plans to oversee a transitional period in the country. These developments introduce additional uncertainty into the regional geopolitical environment. If international and domestic conditions for Argentina were to worsen due to the aforementioned factors, the Argentine economy could be negatively affected as a result of lower international demand and lower prices for its products and services, higher international interest rates, lower capital inflows and higher risk aversion, which may also adversely affect our business, results of operations, financial condition and cash flows. Argentina’s financial and equity markets are also influenced by economic and market conditions in other markets as the reactions of international investors to any of the developments described herein may produce a “contagion” effect that negatively impacts an entire region or investment class. Changes in U.S. trade and other policies under the new U.S. administration may adversely impact our business, financial condition, and results of operations. The U.S. government has indicated its intent to alter its approach to international trade policy and in some cases to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements and treaties with foreign countries and has made proposals and taken actions related thereto. In addition, the U.S. government has recently imposed tariffs on certain foreign goods ranging from 10% to 50% and has indicated a willingness to impose tariffs on imports of other products. Some foreign governments have instituted retaliatory tariffs on certain U.S. goods and have indicated a willingness to impose additional tariffs on U.S. products. The imposition of these tariffs and other recent trade policies by the U.S. government have already caused substantial volatility in the international markets and could result in more volatility in the future. In particular, these tariffs could disrupt global trade flows and impact on the cost and availability of telecom equipment and technology and increase operational costs for companies reliant on international supply chains. Further, the U.S. government recently issued proclamations re-imposing and expanding 25% tariffs on imported steel and aluminum products under Section 232 of the Trade Expansion Act of 1962. These tariffs apply to all countries that previously received exemptions, increase aluminum tariffs from 10% to 25%, and expand the scope of existing steel and aluminum tariffs to include derivative products. The new tariffs took effect on March 12, 2025 and could increase the cost of critical telecommunications infrastructure and equipment, particularly for companies like us that rely on imports for network expansion and maintenance. Additionally, heightened scrutiny on tariff classifications and increased enforcement measures by U.S. authorities could lead to further supply chain disruptions and additional costs. Given our reliance on imported telecommunications equipment, changes in U.S. trade policies that cause disruption in the international market may materially adversely impact our costs and ability to import such equipment. For example, if our access to key suppliers or technology is restricted, or if our customers face economic constraints due to increased costs of goods and services resulting from international tariffs, trade restrictions, or changes in U.S. or foreign government regulations, our financial condition and results of operations could be materially and adversely affected. See “—Risks Relating to Telecom and its Operations—Any failure by a strategic supplier to comply with its legal and contractual obligations could adversely affect our operations and any action or restriction by a foreign government against a strategic supplier could adversely affect our reputation.” Argentina’s ability to obtain financing from international markets is limited, which could affect its capacity to implement reforms and sustain economic growth. Argentina has experienced financial distress since its default on certain debt payments in 2001, 2014 and 2020. During 2020, the Argentine government entered into negotiations with its creditors to restore the sustainability of its external public debt. By August of that year, the Argentine government restructured approximately US$66.5 billion of its U.S. dollar-denominated global bonds. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 22 Table of Contents During the first quarter of 2022, the Argentine government reached a new agreement with the IMF in order to renegotiate the principal maturities of the US$44.1 billion disbursed between 2018 and 2019 under an SBA, originally planned for the years 2021, 2022 and 2023. On January 28, 2022, the Argentine government and the IMF announced that they had reached an understanding on key policies as part of their ongoing discussions relating to an IMF-supported program. Later, on March 3, 2022, the IMF and the Argentine government reached a staff-level agreement on the economic and financial policies to be supported by a 30-month extended fund facility arrangement (the “EFF Agreement”), which was approved by the Argentine Congress through Law No. 27,668 on March 17, 2022, and enacted by Decree No. 130/22. Subsequently, the executive board of the IMF approved the EFF Agreement for an amount equivalent to US$44 billion, including an immediate disbursement of US$9.6 billion. As of the year ended December 31, 2023, the IMF Executive Board and the Argentine authorities reached a staff-level agreement on the first to the sixth reviews, under the extended fund facility arrangement. On February 1, 2024, the IMF Executive Board concluded the seventh review of the agreement under the IMF extended fund facility for Argentina. The decision of the Executive Board enables an immediate disbursement of approximately US$4.7 billion (or Special Drawing Rights “SDR” 3.5 billion) to support the significant efforts of the new authorities to restore macroeconomic stability and get the program back on track. On May 14, 2024, the eighth review of the program took place, which focused on fiscal compliance during the first quarter of 2024. According to the Ministry of Economy’s figures, the primary fiscal surplus was four times higher than the figure required by the current program. In turn, under the 2018 agreement, the BCRA is expected to make a payment of US$1.9 billion and after which only a last principal payment of approximately US$640 billion will remain and, from that moment on, the BCRA will make calendar interest and surcharge payments until September 2026, when the repayment process of the current Extended Facilities Program is expected to begin. In this sense, on June 13, 2024, the IMF Executive Board concluded the eighth review of the agreement under the IMF extended fund facility for Argentina. The decision of the Executive Board enabled an immediate disbursement of approximately US$0.8 billion. Under Executive Order No. 179/2025 of March 10, 2025, the Argentine government authorized a new credit operation with the IMF, featuring a 10-year amortization schedule, to repay debts owed to the IMF itself and amounts due under notes issued to the BCRA. On April 11, 2025, the Argentine government announced it had reached an extended facilities agreement with the IMF for an amount of US$ 20,000 million, of which US$ 15,000 million constitute freely available disbursements in 2025. As reported by the Ministry of Economy and the BCRA in their announcement dated April 11, 2025, other international agencies are expected to provide additional disbursements for approximately US$ 6.1 billion that will complement the disbursements to be made by the IMF during 2025. Overall, these agreements have the potential to contribute to an increase of US$ 23,100 million in the BCRA’s liquid reserves during 2025. Finally, the BCRA has agreed to an additional twelve-month extension of the activated tranche of the currency swap with the Central Bank of China (PBOC) (for approximately US$5 billion). On October 28, 2022, the Minister of Economy announced a new agreement with the Paris Club, which is an addendum to the Paris Club 2014 Settlement Agreement. This new agreement recognizes a principal amount of US$1.971 billion, extending the repayment period to thirteen semi-annual installments, starting in December 2022 to be repaid in full in September 2028. As part of the agreement, the interest rate applicable to the first three installments was reduced from 9% to 3.9%, with subsequent gradual increases to 4.5%. The payment profile implies semi-annual payments averaging US$170 million (principal and interest included). In early April 2023, the former Minister of Economy, Sergio Massa, signed agreements with the Netherlands, Germany, Canada, Israel, Finland, Denmark and Austria, part of the negotiations between the Argentine government and the group of creditor countries of the Paris Club to finalize the payment of the obligations in 2028. During 2024 and into 2025, Argentina continued its engagement with the IMF under the EFF Agreement, with further program reviews conducted and disbursements subject to compliance with fiscal, monetary and structural benchmarks. Discussions between the Argentine authorities and the IMF regarding the continuation of the program and policy implementation remained ongoing as of 2025. As of 2025, Argentina continued to service its obligations under the amended Paris Club agreement, with semi-annual payments made in accordance with the agreed repayment schedule through 2028. We cannot assure you that the EFF Agreement will not affect Argentina’s ability to implement reforms and public policies and boost economic growth. In addition, the long-term impact of these measures and any future measures taken by the current government on the Argentine economy remains uncertain. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 23 Table of Contents Despite the restructuring of Argentina’s public debt carried out between 2020 and 2022, international markets remain cautious about Argentina’s debt. Although Argentina country risk indicator began to decline significantly, there can be no assurance that Argentina’s credit ratings will remain in place or otherwise be downgraded, suspended or cancelled. Any downgrade, suspension or cancellation of Argentina’s sovereign debt rating may have an adverse effect on the Argentine economy and our business. Without renewed access to financial markets, the Argentine government may not have the financial resources to implement reforms and drive growth. Argentina’s inability to obtain credit in international markets could have a direct impact on our ability to access those markets to finance our operations and growth, including the financing of capital expenditures, which would adversely affect our financial condition, results of operations and cash flows. In addition, we cannot predict the outcome of any future restructuring of Argentine sovereign debt. We have investments in Argentine sovereign bonds in the amount of P$322,392 million as of December 31, 2025. Any new event of default by the Argentine government could adversely affect their valuation and repayment terms, as well as have a material adverse effect on the Argentine economy and, consequently, our business and results of operations. The Argentine banking system may be subject to instability which may affect our operations. Although the financial system’s deposits continue to grow in nominal terms, they are mostly short-term deposits and the sources of medium and long-term funding for financial institutions are currently limited. In 2025, nominal private sector deposits in Argentine pesos expanded by approximately 41.3% in real terms year-over-year. During the same period, private sector deposits in foreign currency increased by around 17.6%. In addition, loans to the private sector in foreign currency grew by roughly 71.7% in 2025 (in currency of origin). Financial institutions are particularly subject to significant regulation from multiple regulatory authorities, all of which may, among other things, establish limits on commissions and impose sanctions on financial institutions. The lack of a stable regulatory framework, or changes to such regulatory framework by the Argentine government, could impose significant limitations on the activities of financial institutions and could induce uncertainty with respect to the financial system stability. The persistence of the current economic crisis or the instability of one or more of the larger banks, public or private, could have a material adverse effect on the prospects for economic growth and political stability in Argentina, resulting in a loss of consumer confidence, lower disposable income and fewer financing alternatives for consumers. These conditions would have a material adverse effect on us by resulting in lower usage of our services, lower sales of devices and the possibility of a higher level of uncollectible accounts or an increase in the credit risk of the counterparties regarding the Company investments in local financial institutions. In addition, exchange controls and restrictions on transfers abroad and capital inflows limit the availability of international credit. We are subject to Argentine and international anti-corruption, anti-bribery and Anti-Money Laundering Laws and may be subject to compliance with economic and trade sanctions programs. Our failure to comply with these laws and programs could result in penalties, which could harm our reputation and have an adverse effect on our business, financial condition and results of operations. The United States Foreign Corrupt Practices Act of 1977 (“FCPA”), the Organization for Economic Co-Operation and Development Anti-Bribery Convention, the Argentine Corporate Criminal Liability Law (Ley de Responsabilidad Penal Empresaria), and other applicable anti-corruption laws prohibit companies and their intermediaries from offering or making improper payments (or giving anything of value) to government officials and/or persons in the private sector for the purpose of influencing them or obtaining or retaining business and require companies to keep accurate books and records and maintain appropriate internal controls. In particular, the Argentine Corporate Criminal Liability Law provides for the criminal liability for corporate entities for criminal offences against public administration and transnational bribery committed by, among others, its attorneys-in-fact, directors, officers, employees, or representatives. Relatedly, we may be subject to compliance with economic and trade sanctions programs, including certain of which that are administered by the U.S. Department of the Treasury’s Office of Foreign Assets Control (“OFAC”), which prohibit or restrict transactions or dealings with certain territories, governments, organizations, and individuals. Although these programs differ from one sanction regime to another, to be subject to sanctions compliance requirements, such activities generally need to occur within the jurisdiction of the sanctioning authority. Failure to comply with any anti-corruption, anti-bribery or Anti-Money Laundering Laws or economic and trade sanctions programs could subject us to legal and reputational consequences, including civil and criminal penalties. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 24 Table of Contents It may be possible that, in the future, there may emerge in the press allegations of instances of misbehavior on the part of former agents, current or former employees or others acting on our behalf or on the part of public officials or other third parties doing or considering business with us. We will endeavor to monitor such press reports and investigate matters that we believe warrant an investigation in keeping with the requirements of compliance programs and, if necessary, make disclosure and notify the relevant authorities. However, any adverse publicity that such allegations attract may have a negative impact on our reputation and lead to increased regulatory scrutiny of our business practices. Our subsidiary Micro Sistemas is subject to Argentine Anti-Money Laundering Laws and administrative regulations that conform, in particular, to the international standards established by the Financial Action Task Force (FATF-GAFI) (the “Anti-Money Laundering Laws”) that prohibit, among other things, their involvement in receiving and/or transferring the proceeds of criminal activities and impose obligations to identify the users and beneficial ownership and request certain information and documentation that, in certain circumstances, must be shared with regulators or government institutions. In Paraguay, our subsidiary Personal Envíos is subject to laws that prevent and repress illegal acts intended to legitimize money or assets, and to resolutions that regulate the Prevention of Money Laundering and Financing of Terrorism directed at Electronic Payment Media Companies authorized by the Central Bank of Paraguay. See “Item 4—Information on the Company— Regulatory Authorities and Framework.” Failure to comply with Anti-Money Laundering Laws could result in significant administrative and/or criminal sanctions as provided in such regulations. On February 10, 2025, President Trump issued an executive order pausing FCPA enforcement for 180 days and directing the Department of Justice (“DOJ”) to revise its enforcement guidelines to prioritize U.S. economic and security interests. This pause ended on June 9, 2025, with the DOJ’s issuance of new enforcement guidelines. In addition to risks generated by uncertainty regarding how these guidelines will be implemented, we may face an increased risk of stricter FCPA enforcement if the new guidelines result in more scrutiny toward non-U.S. companies such as Telecom Argentina. We believe that our past and current activities comply with applicable anti-corruption, anti-bribery and Anti-Money Laundering Laws and economic and trade sanctions programs. However, such laws and programs are complex and subject to significant discretion by the relevant authorities. As a result, we cannot provide any guarantees that our activities will not be challenged in the future, which could have a material adverse effect on our results of operations. If we or individuals or entities that are or were related to us are found to be liable for violations of applicable anti-corruption, anti-bribery or Anti-Money Laundering Laws (either due to our own acts or our inadvertence, or due to the acts or inadvertence of others) or economic and trade sanctions programs, we or other individuals or entities could face civil and criminal penalties or other sanctions, which in turn could have a material adverse impact on our reputation, business, financial condition and results of operations. We maintain limited commercial relationships with telecommunications carriers in countries designated by the U.S. Department of State as state sponsors of terrorism, which could expose us to reputational, regulatory, or sanctions-related risks We maintain roaming agreements with telecommunications carriers in certain countries designated by the U.S. Department of State as state sponsors of terrorism, including Cuba and Syria, primarily through our operations in Argentina and our subsidiary Núcleo in Paraguay. We also route international traffic to and from these designated countries through third-party international carriers. While we do not maintain direct commercial relationships with carriers in North Korea, and certain agreements generate minimal or no billable traffic, our involvement in telecommunications services that directly or indirectly relate to designated countries could expose us to U.S. economic sanctions, export control restrictions, or other regulatory measures. Such exposure could result in reputational harm, limitations on our ability to access U.S. capital markets or conduct business with U.S. entities, regulatory penalties, or restrictions on our operations, any of which could adversely affect our business, financial condition, and results of operations. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 25 Table of Contents There can be no assurances regarding the consequences of the post-closing review of Argentine regulatory authorities in connection with the Acquisition. On February 24, 2025, we completed the acquisition of TMA for a purchase price of US$1,245 million (P$1,660,045 million in current currency as of December 31, 2025), pursuant to which we (i) assumed a debt owed to TMA in the amount of US$126 million (P$167,887 million in current currency as of December 31, 2025) and (ii) paid in cash US$1,119 million (P$1,492,158 million in current currency as of December 31, 2025) using funds obtained from the Existing Loans. The Acquisition is subject to a post-closing evaluation by ENACOM and the ANC (formerly the CNDC as detailed below). Telecom Argentina is seeking ENACOM’s approval for the change of control in TMA resulting from the Acquisition. In addition, the Secretary of Industry and Commerce (or its successor under Law No. 27,442), must decide whether it authorizes the economic concentration resulting from the Acquisition. As part of the relevant antitrust procedures, the ANC must render its opinion on the requested authorization. All approvals must comply with applicable regulatory and antitrust requirements and include an analysis of market concentration levels in Telecom’s operating sectors. On March 21, 2025, Telecom Argentina was notified of the resolution of the Secretary of Industry and Commerce requiring Telecom Argentina, as a provisional measure in accordance with Article 44 of Law No. 27,442 (the “March 2025 Resolution”), to refrain from carrying out any type of legal, corporate and/or commercial act that directly or indirectly relates to the integration or consolidation of TMA’s businesses with Telecom Argentina for a period of six months or until the Secretary of Industry and Commerce issues a decision regarding the Acquisition, including (i) any initiative that integrates TMA’s equipment with that of Telecom Argentina, and (ii) any exchange of competitively sensitive information with TMA, such as prices and pricing strategies, costs and margins, business plans and commercial strategies and information on customers and suppliers, investment plans, among others. Such resolution further provided that Telecom Argentina must respect the agreements regarding the reciprocal use of infrastructure previously entered into between Telecom Argentina and TMA. As of the date of this Annual Report, TMA operates as an independent business under a separate business segment from Personal, and the members of the Board of Directors and the management of Telecom Argentina and TMA are independent of each other. On April 6, 2025, Telecom Argentina filed an appeal against the aforementioned resolution. Telecom Argentina has also appealed the note from the Secretary of Industry and Commerce to the CNDC dated March 27, 2025 appointing a monitoring agent for Telecom Argentina and TMA, in order to oversee compliance with the measures approved by the resolution of the Secretary of Industry and Commerce referred to above. On June 5, 2025, Telecom Argentina was notified of the decision of the Chamber III of the Federal Court of Appeals on Civil and Commercial Matters which resolved to grant the Telecom Argentina’s appeal, thereby suspending the effects of the Resolution and the note respectively issued by the Secretary of Industry and Commerce on March 21 and March 27, 2025, and further ordering the Secretary of Industry and Commerce to refrain from taking any measure contrary to such suspension. In addition, on June 19, 2025, Telecom Argentina was notified of a resolution of the Secretary of Industry and Commerce that included (i) a statement of objection to the transaction; (ii) a request for Telecom Argentina to present its arguments against the objections within 15 days, and (iii) a call for a special hearing to consider the measures proposed by Telecom Argentina to overcome these objections. Telecom Argentina submitted its arguments on August 5, 2025, and hearings were held on September 19, 2025, and October 6, 2025. The CNDC resolved to adjourn the proceedings pending its assessment of the observations submitted by Telecom Argentina and additional information requested from third parties that remains to be submitted. On August 5, 2025, Telecom Argentina timely submitted its response to the preliminary objection report issued by the CNDC. Together with that submission, and without this being construed as an acknowledgment that the transaction raises an antitrust concern, Telecom Argentina expressed its willingness, as a procedural safeguard contemplated under Law No. 27,442, to consider potential commitments to address the provisional concerns outlined in the objection report, should the authorities deem it necessary. Telecom Argentina believes that any such potential commitments, if required, would be limited, proportionate, and would not have a material adverse effect on the Company’s business, financial condition, or ability to meet its financial obligations. On November 17, 2025, pursuant to Decree No. 810/2025, the Argentine Government established the Argentine National Competition Authority (“ANC”), a decentralized and autonomous entity that replaced the CNDC. The ANC became formally operational upon the appointment of its authorities in accordance with Law No. 27,442, which establishes its role as the entity responsible for protecting and promoting competition and safeguarding the general economic interest. As a result, the regulatory review related to the Acquisition is conducted under the supervision of the ANC. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 26 Table of Contents On December 23, 2025, Chamber III of the Federal Court of Appeals on Civil and Commercial Matters declared it unnecessary to rule on the appeal filed by Telecom Argentina against Resolution No. 63/2025 issued by the Secretary of Industry and Commerce, given that at the time the judgment was rendered, the precautionary measure had already expired. In this regard, the Chamber expressly noted that the case record did not demonstrate the existence of an extension of the precautionary measure and therefore concluded that no current case or controversy remained to warrant consideration of the claim. The Argentine Government filed a Federal Extraordinary Appeal against this resolution, which has been notified to Telecom Argentina on February 23, 2026. Telecom Argentina has duly responded within the established timeframe, requesting that the appeal be dismissed as inadmissible. Likewise, on that same date, a new hearing was held within the framework of the procedure established in Article 14 of Law No. 27,442 before the ANC, which constituted a continuation of the previously mentioned hearings. With the holding of this hearing, the hearing stage provided for in the procedure was deemed concluded, leaving the case under review by the ANC for the issuance of the corresponding resolution within the framework of the operation’s review process. There can be no assurance as to the outcome of such appeal process or the consequences of the post-closing evaluation of the Acquisition by regulatory and antitrust authorities. If the injunction referenced above is overturned and/or the above-mentioned regulatory measures are extended, or if regulatory or antitrust authorities impose conditions or require divestitures (which may include the divestiture of our interest in all or certain assets of TMA, including, among others, the spectrum assets), it could have a material adverse effect on our business strategy, financial condition, and future growth. Such conditions or requirements could also result in breaches of covenants under the Existing Loans, which, in turn, could trigger an event of default under such loans. Any potential divestitures at a lower-than-expected-price could have an adverse effect on our results or financial condition. Additionally, complying with potential regulatory or antitrust requirements imposed by the relevant authorities, such as asset divestitures or restrictions on legal, corporate and/or commercial activities related to the integration or consolidation of TMA’s businesses with Telecom Argentina’s, could delay the realization of anticipated benefits from the Acquisition and increase associated costs. For more information on the recent acquisition of TMA, see “Item 4—Information on the Company— Recent Developments—Acquisition of TMA.” Risks Relating to Telecom and its Operations We may become subject to burdensome regulations, ordinances and laws affecting the services we offer which could adversely affect our operations. Activities in the fixed and mobile telephony, cable television and internet businesses are subject to risks associated with the adoption and implementation of laws and governmental regulations that reflect changing governmental policies over time. The Argentine government has historically exercised significant influence over the economy, and telecommunications companies have operated in a highly regulated environment. In the past, the Argentine government promulgated numerous, far-reaching regulations affecting the economy and telecommunications companies. In addition, local municipalities in the regions where we operate have also introduced regulations and proposed various taxes and fees for the installation of infrastructure, equipment and expansion of fixed line and mobile networks. For example, municipalities usually restrict areas where antennas may be deployed, negatively impacting our mobile service coverage, which in turn affects the quality of our services. Municipal and provincial tax authorities have also brought an increasing number of claims against us, which we are replying. If changes to existing laws and regulations lead to negative consequences for the Company, our business, financial condition, results of operations and cash flows may be adversely affected. After the deregulation of Argentina’s telecommunications and media industries, the Broadcasting Law, No. 26,522, the LAD and their implementing regulations have been amended on several occasions, modifying requirements to hold or transfer broadcasting licenses. Although the current administration generally favors deregulation and limited state intervention in the private sector, we cannot guarantee that we will not be subject to further regulations in the future. Such regulations could necessitate adjustments to our subscription service prices, potentially having a materially adverse impact on our revenues. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 27 Table of Contents Moreover, in certain municipalities, regulations have been adopted requiring us to upgrade and/or modify our cable television systems. We will seek to continue to upgrade our existing cable systems, including any network upgrades or modifications required by regulatory or local authorities if we have sufficient cash flow and financing is available at commercially attractive rates. Although currently applicable local ordinances provide that certain penalties may be imposed, including the suspension of the right to use the air space, municipalities have generally not imposed penalties on non-compliant cable systems operators. As of the date of this Annual Report, no fines have been imposed on us in relation to this matter. The laws related to the commitments to maintain certain coverage and quality of services require and may require significant capital expenditure from Telecom for both Personal and TMA networks. Additionally, many municipal governments have issued regulations that, in our view, exceed their authority, which frequently limit, hinder or restrict the installation of the infrastructure required to comply with such commitments. Therefore, such legislation negatively impacts on the obligations that we and our competitors assumed. In relation to Fintech Services, we are subject to BCRA regulation for all services provided by Personal Pay. Any failure to comply with current regulations could generate regulatory exposures that entail sanctions and reputational exposures for the business. We may also be subject to additional and unexpected governmental regulations in the future. For more information on the regulatory framework, see “Item 4—Information on the Company—Regulatory Authorities and Framework.” We operate in a highly competitive environment that could materially erode our market position. The telecommunications industry is currently undergoing a paradigm shift, driven by the entry of global competitors into local markets and the progressive dismantling of traditional geographic barriers. Connectivity is no longer constrained by the physical infrastructure deployed within a given country. It can now be delivered from space through low-earth orbit (LEO) satellite constellations or through digital platforms operating without a local physical footprint. This shift has fundamentally reshaped the competitive landscape, enabling global technology companies to compete directly with traditional telecommunications operators across multiple markets, including internet access, entertainment distribution, and enterprise services. The increasing availability of satellite-based internet services, the expansion of OTT entertainment platforms operating without a local presence, and the consolidation of hyperscale technology providers in the enterprise solutions market are eroding the historical advantages of scale, coverage and infrastructure traditionally enjoyed by incumbent operators. Fintech Services are also becoming increasingly competitive with the growth of several fintechs established in Argentina. In addition, new competitors are in process to require local Bank licenses. With respect to our digital wallet, Personal Pay competes with existing digital and offline payment methods, including banks and other providers of traditional payment methods that serve both merchants and individuals. We also compete in the rapidly evolving fintech space with local and strong global players that offer digital financial services such as access to credit, virtual and physical cards, insurance, savings accounts and asset management. Technological innovation relating to fixed and mobile telephony, cable television, internet transmission and Fintech Services increases the level of competition that we face and requires us to make frequent investments to develop new and innovative programming services and products to attract and retain fixed and mobile telephony, cable television, internet and Fintech Services customers. We cannot assure you that we will be able to make the investments necessary to remain competitive, or that we will be able to attract new and retain our current customers. A substantial loss of customers to competitors would have a material adverse effect on our business and results of operations. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 28 Table of Contents The rapid adoption of OTT and satellite internet services is contributing to a significant decline in our traditional revenue streams and is challenging our legacy business model. In the entertainment market, the proliferation of new streaming platforms—such as Disney+, Max, Paramount+, Star+, and Amazon Prime Video, among others—has fundamentally transformed audiovisual consumption patterns. These platforms offer global content libraries, exclusive original content, and highly personalized user experiences. In addition, high-profile sporting events—such as the Club World Cup, broadcast exclusively by digital platforms without the intermediation of traditional operators (DAZN)—have underscored the emergence of a new direct-to-consumer distribution model that challenges the historical role of operators as content aggregators. Although our Flow platform has evolved to integrate both linear and on-demand content and has incorporated advanced digital features, the risk remains: if we fail to maintain a differentiated and compelling value proposition, we may lose competitive momentum vis-à-vis these global platforms, adversely affecting our ability to retain and acquire subscribers. In the mobile market, competition has intensified due to heightened consumer price sensitivity, the ease of switching providers through number portability, and the proliferation of usage models based on public Wi-Fi networks and OTT applications that substitute traditional voice and messaging services. This dynamic is particularly pronounced in the prepaid line of business, where users tend to use multiple SIM cards or prioritize mobile data usage to access digital services provided by third parties. This landscape is further compounded by an emerging risk: the development of Direct-to-Cell (D2C) satellite connectivity solutions, which enable mobile devices to connect directly to satellite constellations without the need for intermediary terrestrial infrastructure. This technology, driven by global players with large-scale deployment capabilities, could materially alter competitive conditions in the mobile market, particularly in rural or low-density areas where traditional networks face higher coverage costs. Although widespread adoption remains subject to technical, regulatory, and commercial factors, the advancement of the D2C model represents a potential threat to established mobile operators by introducing an alternative connectivity solution that bypasses local network infrastructure and could capture a meaningful share of demand in certain market lines of business. In the internet access market, the emergence of low-Earth orbit (LEO) satellite service providers has introduced a structural shift in competitive dynamics. Because these technologies do not rely on terrestrial network infrastructure, they enable immediate nationwide coverage and unprecedented scalability, positioning them as a viable alternative to traditional fixed-line networks. For example, Starlink has experienced rapid growth since its commercial launch in Argentina, reaching a meaningful subscriber base in less than one year and demonstrating strong demand for connectivity solutions that are independent of local infrastructure. This landscape is further shaped by the anticipated entry of additional global operators, such as Amazon’s Project Kuiper and OneWeb, which have already obtained regulatory authorizations to operate in the country and have announced ambitious deployment plans supported by strategic partnerships and advanced technological capabilities. This new generation of competitors—characterized by highly efficient business models and immediate coverage—poses a direct challenge to incumbent operators by lowering barriers to entry and increasing pressure on pricing, service quality, and innovation speed. If we fail to sustain an adequate level of investment to preserve the competitiveness of our network, we could experience a loss of market share in this key line of business. In addition, the growing demand for symmetric connectivity, low latency, and continuous availability requires the ongoing evolution of our fixed and transport network infrastructure, which entails sustained efforts in terms of investment, operational efficiency, and technological adaptability. This competitive landscape is further intensified by the expansion of fixed wireless access (FWA) services offered by mobile operators, which compete for the same residential and enterprise customer base, thereby increasing competitive pressure in the internet market. In the enterprise solutions market, the technology industry is also undergoing a profound transformation. Traditional point-to-point connectivity architectures are increasingly being displaced by software-defined networking solutions, including SD-WAN, offered directly by global hardware manufacturers and cloud platform providers. These participants—including the leading hyperscalers—have begun offering virtualized connectivity, cybersecurity, data storage and processing services, vertically integrating the value chain and competing directly with traditional operators in the B2B line of business. In this new environment, customer value no longer resides solely in connectivity, but rather in the ability to deliver customized, integrated and scalable digital solutions. The risk to our Company lies in our potential inability to adapt our value proposition with sufficient agility, which could result in a loss of relevance relative to competitors with greater innovation capacity, faster deployment speed, and a broader global footprint. Taken together, the entry of non-traditional competitors, the ongoing technological disruption, and the increasing sophistication of demand are creating unprecedented competitive pressure. Absent an effective strategic response—grounded in innovation, operational efficiency, and strategic partnerships—we could face a progressive erosion of our customer base and a material decline in revenues and operating results. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 29 Table of Contents Technological advances and replacement of our equipment may require us to make significant expenditures to maintain and improve the competitiveness of the services we offer. Our industry is subject to significant changes in technology and the introduction of new products and services. We cannot predict the effect of technological changes on our business. New services and technological advances related to the telecommunications, cable television, internet, digital solutions and Fintech Services industries are likely to offer additional opportunities to compete against us on the basis of cost, quality or functionality. It may not be practicable or cost-effective for us to replace or upgrade our installed technologies in response to our competitors’ actions. Responding to such change may require us to devote substantial capital to the development, procurement or implementation of new technologies, and may depend on the final cost in local currency of imported technology and our ability to obtain additional financing. No assurance can be given that we will have the funds to make the capital expenditures to improve our systems, compete with others in the market or replace equipment used in connection with our businesses. Moreover, internet, cable television, mobile telephony, corporate data and IoT services are characterized by rapidly changing technology, evolving industry standards, changes in customer preferences and the frequent introduction of new services and products. To remain competitive, we must invest in networks, constantly upgrade our access technology and software for the internet service market, improve the commercial offers and the user experience and continue to enhance our mobile networks by expanding our network. There can be no guarantees that our attempts to innovate and diversify our business will be successful. Future technological developments may result in decreased customer demand for certain of our services or even render them obsolete. In addition, as new technologies develop, equipment may need to be replaced or upgraded or network facilities (in particular, mobile and internet network facilities) may need to be rebuilt in whole or in part, at substantial cost, to remain competitive. These enhancements and the implementation of new technologies will continue requiring increased capital expenditures. The intellectual property used by us, our suppliers or service providers may infringe on intellectual property rights owned by others. Some of our products and services use intellectual property that we own or license from others. We also provide content we receive from content producers and distributors, such as video games, video, including TV programs and movies, and we outsource services to service providers, including billing and customer care functions, which incorporate or utilize intellectual property. We and some of our suppliers, content distributors and service providers may receive in the future, assertions and claims from third parties that the content, products or software utilized by us or our suppliers, content producers and distributors and service providers infringe on the patents or other intellectual property rights of these third parties. These claims could require us or an infringing supplier, content distributor or service provider to cease engaging in certain activities, including selling, offering and providing the relevant products and services. Such claims and assertions also could subject us to costly litigation and significant liabilities for damages or royalty payments or require us to cease certain activities or prevent us from selling certain products or services. Our revenues may be adversely affected by an increase in churn rates, with respect to mobile telephony, cable television, internet services, corporate data services and IoT, or reductions in fixed telephony lines in service, with respect to fixed telephony services. Our revenues depend significantly on our ability to retain customers by limiting churn rates, with respect to mobile telephony, cable television, internet services, data services and IoT, or net reductions in fixed telephony lines in service, with respect to fixed telephony services. Any substantial increase in churn rates, with respect to mobile telephony, cable television and internet services, or reductions in lines in service, with respect to fixed telephony services, may have a material adverse effect on our revenues and results of operations. For further information about churn rates see “Item 4—Information on the Company—Management of Churn” and “Item 5—Operating and Financial Review and Prospects—Consolidated Results of Operations—(A.1) 2025 Compared to 2024.” Actual or perceived health risks or other problems relating to mobile handsets or transmission masts could lead to litigation or decreased mobile communications usage. The effects of, and any damage caused by, exposure to an electromagnetic field were and are the subject of careful evaluations by the international scientific community, but until now there is no scientific evidence of harmful effects on health. We cannot rule out that exposure to electromagnetic fields or other emissions originating from wireless handsets will not be identified as a health risk in the future. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 30 Table of Contents Telecom complies with the international security standards established by the World Health Organization and Argentine regulations -which are similar and mandatory for all Argentine mobile operators. Our mobile business may be harmed as a result of any future alleged health risk. For example, the perception of these health risks could result in a lower number of customers, reduced usage per customer or potential consumer liability, all of which could have a material adverse effect on our financial condition and results of operations. Our operations and financial condition could be affected by future union negotiations, Argentine labor regulations and governmental measures requiring private companies to increase salaries or otherwise provide workers with additional benefits. In Argentina, labor organizations have substantial support and considerable political influence. In recent years, the demands of our labor organizations have increased, mainly because of the increase in the cost of living, which was affected by increased inflation, higher tax pressure over salaries and the consequent decline in the population’s purchasing power. In addition, in the absence of a union agreement concerning convergent services, if we are unable to reach an agreement with the unions on work conditions, or in case of a lack of recognition among union associations, we may be adversely affected by individual labor claims, class actions, higher union contributions expenses, impacts to our operations, impairment of services due to inefficient processes, union conflicts, direct action measures and social impacts which may also affect the quality and continuity of our services to our customers and our reputation. Certain labor and telecommunications unions have initiated claims against the Company alleging non-compliance with certain conditions provided for in the collective bargaining agreements that could allow them to negotiate the inclusion of some suppliers’ employees in their collective bargaining agreements. See Note 20 to our Consolidated Financial Statements. If labor organization claims continue or are sustained, this could result in increased costs, greater conflict in the negotiation process and strikes (including general strikes and strikes by the Company’s employees and the contractors and subcontractors’ employees) that may adversely affect our operations. See “Item 6—Directors, Senior Management and Employees—Employees and Labor Relations.” Chapter 4 of the Decree of Necessity and Urgency No. 70/2023 substantially amended certain labor laws. Mainly, it eases the conditions for hiring and registering personnel, limits the fines and interest rates that can be claimed in court, and declares telecommunications services, as well as sanitary, production, transportation, distribution, and commercialization services related to water, gas, and electricity supply, aviation services, customs and migration services, and childcare and education services, as essential services. In addition, it declared that services such as radio and television, as well as financial services, among others, shall be deemed of paramount importance. The General Confederation of Labor (CGT), along with other trade unions, requested that these provisions in Chapter 4 be declared unconstitutional, and obtained an injunction that ordered the suspension of its application. On January 30, 2024, the National Court of Appeals on Labor Matters issued a ruling declaring the unconstitutionality of these provisions. As of date of this Annual Report, the Supreme Court of Argentina has not yet issued a final ruling. While the Ley de Bases (which incorporated several of the main amendments proposed by DNU No. 70/2023 to the Labor Contract Law) is intended to increase legal certainty for Argentine employers, we can provide no assurances that such a result will be achieved or that the law will not change again in the future. For more information on the Ley de Bases, see “—Economic and political reforms in Argentina, and future policies of the Argentine government may affect the economy as well as the operations of the telecommunications industry.” We are or may be involved in legal and regulatory proceedings that could result in unfavorable decisions and financial penalties for us. We are party to a number of legal and regulatory proceedings, some of which have been pending for several years. We cannot be certain that these claims will be resolved in our favor. Responding to the demands of litigation claims and responding to, or initiating proceedings against, regulatory bodies may divert management’s time attention and financial resources. Further, customers and consumers’ trade unions have in the past initiated different claims against us regarding alleged improperly billed charges. Although we have taken certain actions to reduce risks in connection with these claims, we cannot assure that new claims will not be filed against us in the future. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 31 Table of Contents The Company has been subject to technical sanctions from regulatory bodies, mainly related to the delay in repairing defective lines, installing new lines and/or service failures. Although sanctions are appealed in the administrative stage, if the appeals are not resolved in our favor in administrative or judicial stage or if they are resolved for amounts larger than those recorded, these proceedings could have an adverse effect on our financial condition, results of our operations and cash flows. We may also be involved in proceedings related to other authorities that have jurisdiction over different aspects of our operations, including, but not limited to, antitrust authorities, the CNV, the public registry of commerce and tax authorities. As of December 31, 2025, we recorded provisions that we estimate are sufficient to cover contingencies considered probable. However, we may face increased risk of employment, commercial, regulatory, tax, consumer trade union and customers’ proceedings, among others. If this occurs, we cannot guarantee that those proceedings will not have an adverse effect on our results of operations and financial condition. See Note 20 to our Consolidated Financial Statements. A cyberattack could adversely affect our business, financial condition, results of operations and cash flow. Information about security risks has increased in recent years as a result of the proliferation of new and more sophisticated technologies and also due to cyberattack activities. As part of our ongoing development and initiatives, more equipment and systems have been connected to the internet. We also rely on digital technology, including information systems to process financial and operational information. Due to the nature of our business and the greater accessibility allowed through the internet connection, we could face an increased risk of cyberattacks. In the event of a cyberattack, we could experience an interruption of our commercial operations, material damage and loss of information; a substantial loss of income, suffering response costs and other economic losses; and it could subject us to more regulation and litigation, affecting our reputation. As a result, a cyberattack could adversely affect our business, results of operations and financial condition and cash flow. In addition, during 2025, we have continued with a hybrid work mode for our employees. This working methodology and the exponential growth of the digital collection channels requires the implementation of several measures in order to grant security in both virtual and on premises operations, which were all implemented successfully. Although Telecom has adopted all required measures to ensure the proper functioning of its operating systems, as well as to ensure our customers’ information, no assurance can be given that we will not be subject to any cyberattacks that could adversely affect our business, result of operations, financial condition and cash flow. As of the date of this Annual Report, our insurance policies do not cover damages caused by cyberattacks and other similar events. For more information about Cybersecurity Risk Management, Strategy and Governance, see “Item 16K—Cybersecurity.” Furthermore, our Fintech Services involve the collection, storage, processing and transmission of customers’ personal data, including financial information. Due to the digital nature of our payment services, third parties may engage in abusive schemes or fraud attacks that are often difficult to detect and may reach a scale that would not otherwise be possible in physical transactions. Fraud schemes and misuse of our payment services could expose us to significant costs and liabilities, require us to change our business practices, result in a loss of customer confidence in, or reduced use of, our products and services, damage our reputation and brands, and divert management’s attention from operating our business. Additionally, as a result of the adoption of new technologies such as Gen AI, the Company could be subject to threats that are increasingly difficult to detect and prevent, considering the development of new attack vectors as well as the improvement of existing ones. The adoption of AI could increase the threat of undetectable attack vectors, which may expose us to cybersecurity vulnerabilities and, in turn, affect our business. For more information regarding risks related to AI, see “—Artificial intelligence presents risks that could adversely affect our business, results of operations and financial condition.” PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 32 Table of Contents Artificial intelligence presents risks that could adversely affect our business, results of operations and financial condition. We increasingly rely on AI technologies, including Gen AI and automated decision-support tools, across several areas of our operations to, among other things, enhance our features for new and existing products, and create greater operation efficiencies. AI systems may produce inaccurate, biased or harmful outputs, release confidential information, infringe on intellectual property rights or result in failures in automated processes, that could adversely affect customer interactions, service quality, or internal decision-making. Misuse or overreliance on AI tools by employees may lead to unintended operational or compliance issues. As we expand the use of AI and rely on third-party AI platforms, we are exposed to the possibility that AI providers may not comply with current or rapidly changing regulatory and industry standards, particularly regarding privacy and data protection resulting in operational disruptions, the loss of intellectual property, exposure of confidential or proprietary information, security breaches, and diminished service quality. The regulatory landscape governing AI is rapidly evolving, and new laws and regulations may introduce compliance challenges, increase our costs or subject us to government enforcement actions or civil litigation. While, as of the date hereof, we have not identified any security breaches or other AI-related challenges, any of these risks, individually or combined, could lead to reputational damage, financial impacts, operational disruptions or legal liability, and could adversely affect our results of operations and financial condition. The impacts of climate change could pose risks of damage to our infrastructure and cause disruptions in our operations, which may affect our financial results. Extreme weather events caused by climate change may damage our infrastructure, disrupt our ability to build and maintain parts of our networks, affect our suppliers in providing the necessary products and services to ensure the quality and coverage of our networks, or require us to incur costs to enhance the climate resilience of our infrastructures. Any of these situations could delay our network deployment plans, disrupt service to our customers, increase our costs, and negatively impact on our operational results. Although we do not currently consider the potential losses or costs associated with the physical effects of climate change to be significant, it remains difficult to accurately and precisely forecast future impacts due to the dynamic nature of climate change and its effects on the environment and we cannot guarantee that such losses or costs will not become significant in the future. Stakeholders’ evolving expectations regarding our ESG practices may impose additional costs or expose us to new risks. Customers, regulators, investors, and other stakeholders are increasingly focused on the ESG practices of companies across all sectors. Concerns about these issues may lead to new or heightened legal and/or regulatory requirements. The market shows great interest in constantly evolving ESG trends. We work proactively to respond to ESG requirements and understand the expectations of our stakeholders. However, our corporate reputation could be damaged if we fail to adapt or meet these changing expectations, or if we do not respond adequately to growing concern about ESG issues, regardless of whether or not there is a legal obligation to do so. Operational risks could adversely affect our reputation and our profitability. Telecom faces significant digital security risks and challenges, operating in an environment attractive to cybercriminals, due to the high volume of data and transactions. This necessitates robust prevention, detection, and control measures to mitigate the risks of internal and external fraud, including the loss or misuse of confidential information. Telecom also prioritizes physical security across all Company sites, as well as of its employees. To this end, we are tasked with implementing measures to protect employee health and safety, including preventing illnesses, accidents and other life-threatening hazards. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 33 Table of Contents Additionally, our infrastructure is geographically dispersed, with both internal and external equipment. Consequently, it is exposed to risks of vandalism, fires, electrical discharges, and physical hazards arising from extreme weather events, such as high temperatures, heatwaves, severe storms and floods. These risks can result in physical injuries to people, damage to assets, material damage to property and building and service interruptions. The evolution of technology challenges us to maintain continuous updating and review of key redundancies to ensure the availability of the service we provide to society. Ensuring the availability of our services drives the constant review of vulnerabilities and design of contingency al long – term mitigation actions. Simultaneously, while we update key systems, unforeseen delays or problems may occur that could involve reviewing end-to-end processes, designing controls, and monitoring indicators to minimize the impact on operations and customer experience. In addition, we manage tax, legal, regulatory, compliance, competition, process, labor, and economic-financial risks. Telecom’s suppliers are contractually obligated to comply with all applicable laws and regulations, including those related to tax, labor, social security, anti-corruption, money laundering, health and safety, and environmental standards. They are also required to adhere to Telecom’s Code of Ethics and Conduct for Third Parties and ensure their employees and subcontractors do the same. Despite our efforts to monitor supplier compliance, we cannot guarantee that all regulations will be fully adhered to, which could expose Telecom to labor and commercial contingencies. Telecom has risk management practices at the highest levels including a Risk Management Committee designed to detect, manage and monitor the evolution of risks. However, the Company can give no assurances that these measures will be successful in effectively mitigating the operational risks we face, and such failures could have a material adverse effect on its results of operations and could damage our reputation. Any failure by a strategic supplier to comply with its legal and contractual obligations could adversely affect our operations and any action or restriction by a foreign government against a strategic supplier could adversely affect our reputation. We rely on strategic suppliers of equipment and materials to provide us with equipment and materials that we need in order to expand and to operate our business. As a result, we are exposed to risks associated with these suppliers, including restrictions of production capacity for equipment and materials, availability of equipment and materials, delays in delivery of equipment, materials or services, and price increases. If these suppliers fail to provide equipment, materials or services to us on a timely basis or otherwise in compliance with the terms of our contracts with these suppliers, we could experience disruptions or declines in the quality of our services, which could have an adverse effect on our revenues and results of operations. Telecom’s suppliers of goods and services are contractually obliged to comply with applicable laws and regulations (including tax, labor, social security, anti-corruption, money laundering standards, etc.). Despite these legal safeguards, as well as monitoring efforts by Telecom, we cannot ensure that our suppliers will comply with all applicable standards. As a result, our financial condition and reputation could be adversely affected. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 34 Table of Contents In particular, trade tensions between the United States and major trading partners, particularly with China, continue to escalate following the introduction of a series of tariffs and export controls by the United States and its trading partners. The U.S. Government is urging other countries to avoid the operations of Chinese companies in their territories, citing concerns regarding potential use of the equipment for espionage. The U.S. Congress and certain regulatory agencies have raised concerns about American companies purchasing equipment and software from Chinese telecommunications companies, including concerns relating to alleged violations of intellectual property rights and potential national security risks. For example, on May 16, 2019, the U.S. government placed Huawei Technologies Co. Ltd (“Huawei”), one of our strategic suppliers in our mobile and fixed telephone networks, and its affiliates on the Entity List, which effectively banned U.S. companies from selling to the Chinese telecoms company without U.S. government’s approval. During 2024 and 2025, the U.S. government expanded export restrictions applicable to Huawei and other Chinese technology companies, including by tightening licensing policies, extending restrictions to certain affiliates and subsidiaries and issuing guidance relating to advanced semiconductors and the enforcement environment for companies that might use or trade such technologies internationally. We cannot predict whether additional restrictions targeting Huawei or other Chinese technology suppliers, including restrictions that would prevent us from acquiring supplies from Huawei or other Chinese technology suppliers in the future, will be adopted or predict the impact that such restrictions may have on our operations. Restrictive covenants in Telecom’s outstanding indebtedness may restrict its ability to pursue its business strategies. Telecom has outstanding borrowings that contain several restrictive covenants that impose significant operating and financial restrictions on it and may limit Telecom’s ability to engage in acts that may be in its long-term best interests, representing 12.2% of total consolidated borrowings. These agreements governing its indebtedness include covenants restricting, among other things, Telecom’s ability to: ● incur or guarantee additional debt; ● enter into sale and leaseback transactions; ● create liens on its assets to secure debt; and ● merge or consolidate with another person or sell or otherwise dispose of all or substantially all of its assets. A breach of any covenant contained in the indentures governing Telecom’s notes or the agreements governing any of its other indebtedness could result in a default under those agreements. If any such default occurs, the holders of such indebtedness may elect (after the expiration of any applicable notice or grace periods) to declare all outstanding amounts, together with accrued and unpaid interest and other amounts payable thereunder, to be immediately due and payable. If any of Telecom’s debt, including its notes, were to be accelerated, its assets may not be sufficient to repay in full that debt or any other debt that may become due as a result of that acceleration. For more information about compliance with covenants see “Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Liquidity—Compliance with Covenants.” We may be adversely affected by fluctuations in interest rates. We are exposed to the fluctuations of interest rates applicable to our indebtedness indexed to variable interest rates. See Note 27 to our Consolidated Financial Statements. We may also incur additional variable-rate debt in the future. Increases in interest rates on variable-rate debt would increase the Company’s interest expense, which would negatively affect our financial costs and cash flows. We may be unable to refinance our outstanding indebtedness, or the refinancing terms may be materially less favorable than their current terms, which would have a material adverse effect on our business, financial condition, results of operations and cash flow. As of December 31, 2025, our total indebtedness, including accrued interest, was P$5,436,615 million, which represents a 43.6% increase compared to our total indebtedness, including accrued interest, as of December 31, 2024. 59.8% of our debt is scheduled to mature in the next three years, including 29.7% scheduled to mature in 2026. For more information, see “Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Borrowings Developments during 2025.” PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 35 Table of Contents There is no assurance that we will be able to extend the maturity or otherwise refinance our outstanding indebtedness, or that we may be required to agree to refinancing terms that may be materially less favorable than the terms of our current loans and notes. Any amendment to or refinancing of our indebtedness could result in higher interest rates and may require us to comply with more burdensome restrictive covenants, which may have a material adverse effect on our business, ability to meet our payment obligations, financial condition, and results of operations. If we are unable to refinance our debt in favorable terms, we may be forced to reduce or delay capital expenditures or research and development expenditures, seek additional equity capital, restructure our debt, curtail or eliminate our cash dividend to stockholders, or sell assets. Non-payment of our obligations or any other default under any of our debt instruments could, in turn, result in a default and acceleration of our other outstanding debt obligations, which would have a further material adverse effect on our business, ability to meet our payment obligations, financial condition, and results of operations. See “—Risks Relating to Argentina—Devaluation of the Argentine Peso and foreign exchange restrictions may adversely affect our results of operations, our capital expenditures and our ability to service our liabilities and pay dividends” and Notes 14 and 27 to our Consolidated Financial Statements. We may not obtain the benefits we expect from the acquisition of TMA in the anticipated timeframe. We have incurred in substantial amount of debt and have devoted significant resources toward the Acquisition, and we cannot assure that we will obtain the benefits we expect. Our failure to obtain these benefits may have an adverse effect on our financial condition and results of operations. The expected synergies and benefits from the Acquisition may not materialize as anticipated, or may take longer to achieve, due to difficulties in merging business operations and integrating technology platforms. Additionally, the financial burden of the Acquisition, including the US$1,170 million in debt financing, may impact our ability to make other strategic investments, increase our leverage, or affect our financial flexibility. If we fail to integrate the acquired business effectively, we may not achieve the expected cost savings, revenue growth, or competitive advantages, which could have a material adverse effect on our financial condition and results of operations. For more information on our financial position, see “Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Liquidity.” For more information on the Acquisition, see Note 29 to our Consolidated Financial Statements Risks Relating to Telecom Argentina’s Shares and ADSs The New York Stock Exchange (“NYSE”) and/or the Buenos Aires Stock Exchange (by delegated authority of BYMA) may suspend trading and/or delist Telecom’s ADSs and Class B common shares, respectively, upon occurrence of certain events relating to Telecom’s financial situation. The NYSE and/or the BYMA may suspend and/or cancel the listing of Telecom’s ADSs and Class B common shares, respectively, in certain circumstances, including upon the occurrence of certain events relating to Telecom’s financial situation. For example, the NYSE may decide such suspension or cancellation if Telecom’s equity becomes negative. The NYSE may in its sole discretion determine on an individual basis the suitability for continued listing of an issuer in the light of all pertinent facts. Some of the factors mentioned in the NYSE Listed Company Manual, which may subject a company to suspension and delisting procedures, include: “unsatisfactory financial conditions and/or operating results,” “inability to meet current debt obligations or to adequately finance operations,” and “any other event or condition which may exist or occur that makes further dealings or listing of the securities on the NYSE inadvisable or unwarranted in the opinion of NYSE.” We cannot assure you that the NYSE and/or BYMA will not commence any suspension or delisting procedures in light of Telecom’s financial situation, including if Telecom’s equity becomes negative. A delisting or suspension of trading of Telecom’s ADSs or Class B common shares by the NYSE and/or BYMA, respectively, could adversely affect Telecom’s results of operations and financial conditions and cause the market value of Telecom’s ADSs and Class B common shares to decline. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 36 Table of Contents Under Argentine corporate law, shareholder rights may be fewer or less well defined than in other jurisdictions. Our corporate affairs are governed by our bylaws and by Argentine corporate law, which differ from the corporate regulatory framework that would apply if we were incorporated in a jurisdiction in the United States (such as Delaware or New York), or in other jurisdictions outside Argentina. Thus, your rights under Argentine corporate law to protect shareholders’ interests relating to actions by our Board of Directors may be fewer and less well defined than under the laws of those other jurisdictions. Although insider trading and price manipulation are illegal under Argentine law, the Argentine securities markets may not be as highly regulated or supervised as the U.S. securities markets or markets in some of the other jurisdictions. In addition, rules and policies against self-dealing and regarding the preservation of shareholder interests may be less well defined and enforced in Argentina than in the United States, or other jurisdictions outside Argentina, putting holders of our Shares and ADSs at a potential disadvantage. Changes in Argentine tax laws may adversely affect the tax treatment of our Class B Shares and/or the ADSs. In 2013, 2017 and 2018, the Argentine legislature modified the Argentine income tax law in a way that impacted the income tax treatment of income derived from the sale, exchange or other disposition of shares and other equity interest (including ADSs), bonds and other securities of Argentine companies. Some of these modifications lead to potentially varying treatment depending on factors such as whether the transaction involved an Argentine non-resident and the source of income. For more information see “Item 10 Additional Information – Taxation.” Consequently, holders of our Class B Shares, including in the form of ADSs, are encouraged to consult their tax advisors as to the particular Argentine income tax consequences of owning our Class B Shares or the ADSs. There can be no assurances regarding the impact of any future modifications to Argentine income tax law on the tax treatment of our Class B Shares and/or the ADSs. Our shareholders may be subject to liability under Argentine law for certain votes of their securities. Under Argentine law, a shareholder’s liability for losses of a company is limited to the value of his or her shareholdings in the company. However, shareholders who have a conflict of interest with us and who do not abstain from voting at the respective shareholders’ meeting may be liable for damages to us, but only if the transaction would not have been approved without such shareholders’ votes. Furthermore, shareholders who willfully or negligently vote in favor of a resolution that is subsequently declared void by a court as contrary to the law or our bylaws may be held jointly and severally liable for damages to us or to other third parties, including other shareholders. The voting rights of investors with respect to the ADSs are limited by the terms of the deposit agreement. The depositary will be treated by us for all purposes as a shareholder with respect to the shares underlying ADSs. A holder of ADRs representing the shares being held by the depositary will not have direct shareholder rights and may exercise voting rights with respect to the Class B shares represented by the ADRs only in accordance with the deposit agreement relating to ADSs. While our direct shareholders will be able to exercise their voting rights either by attending the meeting in person or by proxy, ADR holders may only exercise their voting rights by either withdrawing the shares underlying their ADRs in time for the meeting or instructing the depositary (upon receipt of a notice of the meeting from the depositary) on how to vote the Class B shares represented by their ADRs. Due to these procedural steps involving the depositary, the process for exercising voting rights may take longer for ADR holders than for holders of Class B shares. If no such instructions are received, the depositary shall vote the Class B shares represented by ADSs in accordance with the recommendations Telecom Argentina’s Board of Directors made to all holders of shares, unless the depositary is prohibited from doing so by any applicable provision of Argentine law. The price of our Class B Shares and the ADSs may fluctuate substantially, and your investment may decline in value. The trading price of our Class B Shares is likely to be highly volatile and may be subject to wide fluctuations in response to factors, many of which are beyond our control. The market price of our ADSs decreased by approximately 8% in 2025, increased by approximately 79% in 2024 and increased by approximately 39% in 2023. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 37 Table of Contents The stock markets in general have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the companies involved. We cannot assure you that trading prices and valuations will be sustained. These broad market and industry factors may materially adversely affect the market price of our Class B Shares and the ADSs, regardless of our operating performance. Market fluctuations, as well as general political and economic conditions in the markets in which we operate, such as recession or currency exchange rate fluctuations, may also adversely affect the market price of our Class B Shares and the ADSs, also affecting our estimates of recoverability of our long live assets. In particular, currency fluctuations could impact the value of an investment in Telecom Argentina. Although Telecom Argentina’s ADSs listed on the NYSE are U.S. dollar-denominated securities, they do not eliminate the currency risk associated with an investment in an Argentine company. Future sales of substantial amounts of Telecom Argentina Class B Shares and ADSs, or the perception that such future sales may occur, may depress the price of Telecom Argentina Class B Shares and ADSs. Following periods of volatility in the market price of a company’s securities, that company may often be subject to securities class-action litigation. This kind of litigation may result in substantial costs and a diversion of management’s attention and resources, which would have a material adverse effect on our business, results of operations and financial condition. Restrictions on transfers of foreign exchange and the repatriation of capital from Argentina may impair your ability to receive dividends and distributions on, and the proceeds of any sale of the Class B Shares underlying the ADSs. On September 1, 2019, the Argentine government issued Executive Decree No. 609/19 (as amended) which, inter alia, reinstated certain foreign currency exchange restrictions, most of which had been progressively repealed as from 2015. Decree No. 609/19 was further regulated, amended and complemented by several regulations issued by the BCRA (included, but not limited to, Communication “A” 6844, as further amended, supplemented and restated). Since then, the Argentine government implemented monetary and foreign exchange control measures that included restrictions on the transfer of funds abroad, including dividends, without prior approval by the BCRA or fulfillment of certain requirements. In line with the restrictions that were in place in the past, the BCRA issued new regulations setting forth certain limitations on the flow of foreign currency into and from the Argentine foreign exchange market, aimed both at generating economic stability and supporting the country’s economic recovery. On April 30, 2020, the BCRA issued Communication “A” 7001 (as amended by Communication “A” 7030 and Communication “A” 7042 and as further amended and supplemented from time to time) setting forth certain limitations on the transfer of securities into and from Argentina. Pursuant to Communication “A” 7001 access to the Argentine foreign exchange market for the purchase or transfer of foreign currency abroad (for any purpose) shall be subject to BCRA’s prior approval, if the individual or entity seeking access to the Argentine foreign exchange market has sold securities which settled in foreign currency or transferred any such securities to foreign depositaries during the immediately preceding 90 calendar days. Further, Communication “A” 7001 sets forth that the individual or entity must undertake not to perform any such sale or transfer during the succeeding 90 days after such access. In these cases, the Depositary for the ADSs may hold ADS holders’ Argentine Pesos and may cannot convert them into foreign currency. In addition, Communication “A” 7106 placed certain restrictions on foreign exchange transactions carried out by individuals, specifically with regards to payments with credit cards in foreign currency or with debit cards made abroad. Under Communication “A” 7106, it was also established that non-residents are not allowed to sell securities executed abroad in the local stock market in exchange for foreign currency. We cannot predict how the current restrictions on foreign transfers of funds may change after the date hereof and whether they may limit our ability to fulfill our commitments in general and, in particular, our obligations underlying the ADSs. In addition, any future adoption by the Argentine government of restrictions to the movement of capital out of Argentina may affect the ability of our foreign shareholders and holders of ADSs to obtain the full value of their Class B Shares and ADSs and may adversely affect the market value of the ADSs. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 38 Table of Contents Trading of Telecom Argentina’s Class B Shares in the Argentine securities markets is limited and could experience further illiquidity and price volatility. Argentine securities markets are substantially smaller, less liquid and more volatile than major securities markets in the U.S. In addition, Argentine securities markets may be materially affected by developments in other emerging markets, particularly other countries in Latin America. Our Class B Shares underlying ADSs are less actively traded than securities in more developed countries and, consequently, an ADS holder may have a limited ability to sell the Class B Shares underlying ADSs upon withdrawal from the ADSs facility in the amount and at the price and time that it may desire. This limited trading market may also increase the price volatility of the Class B Shares underlying the ADSs. Holders of ADSs may be adversely affected by currency devaluations and foreign exchange fluctuations. If the Peso exchange rate falls relative to the U.S. dollar, the value of the ADSs and any distributions made thereon from the depositary could be adversely affected. Cash distributions made in respect of the ADSs may be received by the depositary (represented by the custodian bank in Argentina) in Pesos, which will be converted into U.S. dollars and distributed by the depositary to the holders of the American Depositary Receipts (“ADRs”) evidencing those ADSs if in the judgment of the depositary such amounts may be converted on a reasonable basis into U.S. dollars and transferred to the United States on a reasonable basis, subject to such distribution being impermissible or impracticable with respect to certain ADR holders. In addition, the depositary will incur foreign currency conversion costs (to be borne by the holders of the ADRs) in connection with the foreign currency conversion and subsequent distribution of dividends or other payments with respect to the ADSs. The relative volatility and illiquidity of the Argentine securities markets may substantially limit your ability to sell the Class B Shares underlying the ADSs on the BYMA at the price and time desired by the shareholder. Investing in securities that trade in emerging markets, such as Argentina, often involves greater risk than investing in securities of issuers in the United States, and such investments are generally considered to be more speculative in nature. The Argentine securities market is substantially smaller, less liquid, more concentrated and can be more volatile than major securities markets in the United States and is not as highly regulated or supervised as some of these other markets. There is also significantly greater concentration in the Argentine securities market than in major securities markets in the United States. The ten largest companies in terms of market capitalization represented approximately 68.11% of the aggregate market capitalization of the BYMA as of December 31, 2025. Accordingly, although shareholders are entitled to withdraw the Class B Shares underlying the ADSs from the depositary at any time, the ability to sell such shares on the BYMA at a price and time shareholders might want may be substantially limited. We are traded on more than one market and this may result in price variations; in addition, investors may not be able to easily move shares for trading between such markets. Trading in the Class B Shares underlying ADSs or ADSs in the United States and Argentina, respectively, will use different currencies (U.S. dollars on the NYSE and Pesos on the BYMA), and take place at different times (resulting from different trading platforms, different time zones, different trading days and different public holidays in the United States and Argentina). The trading prices of the Class B Shares underlying ADSs on these two markets may differ due to these and other factors. Any decrease in the price of the Class B Shares underlying ADSs on the BYMA could cause a decrease in the trading price of the ADSs on the NYSE. Investors could seek to sell or buy the Class B Shares underlying ADSs to take advantage of any price differences between the markets through a practice referred to as “arbitrage.” Any arbitrage activity could create unexpected volatility in both our share prices on one exchange, and the ADSs available for trading on the other exchange. In addition, holders of ADSs will not be immediately able to surrender their ADSs and withdraw the underlying Class B Shares for trading on the other market without effecting necessary procedures with the depositary. This could result in time delays and additional costs for holders of ADSs. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 39 Table of Contents As a foreign private issuer, we will not be subject to U.S. proxy rules and will be exempt from filing certain reports under the Securities Exchange Act of 1934. As a foreign private issuer, we are exempt from the rules and regulations under the Exchange Act of 1934 (the “Exchange Act”) related to the furnishing and content of proxy statements, and our officers, directors, and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act. In addition, we are not required under the Exchange Act to file annual and current reports and financial statements with the SEC as frequently or as promptly as domestic companies whose securities are registered under the Exchange Act, and we are generally exempt from filing quarterly reports with the SEC under the Exchange Act. In addition, we would lose our foreign private issuer status if a majority of our directors or executive officers are U.S. citizens or residents and we fail to meet additional requirements necessary to avoid loss of foreign private issuer status. Although we have elected to comply with certain U.S. regulatory provisions, our loss of foreign private issuer status would make such provisions mandatory. The regulatory and compliance costs to us under U.S. securities laws as a U.S. domestic issuer may be significantly higher. If we are not a foreign private issuer, we will be required to file periodic reports and registration statements on U.S. domestic issuer forms with the SEC, which are more detailed and extensive than the forms available to a foreign private issuer. We would have to present our financial statements under US GAAP and may also be required to modify certain of our policies to comply with corporate governance practices applicable to U.S. domestic issuers. Such conversion and modifications will involve additional costs. In addition, we may lose our ability to rely upon exemptions from certain corporate governance requirements on U.S. stock exchanges that are available to foreign private issuers. If we do not file or maintain a registration statement and no exemption from the Securities Act registration is available, U.S. holders of ADSs may be unable to exercise preemptive rights granted to our holders of Class B Shares underlying ADSs. Under the GCL, if we issue new shares as part of a capital increase, our shareholders may have the right to subscribe to a proportional number of shares of the same class to maintain their existing ownership percentage (see Section 194 of Argentine Corporations Law). Rights to subscribe for shares in these circumstances are known as preemptive rights. In addition, shareholders are entitled to the right to subscribe for the unsubscribed shares remaining at the end of a preemptive rights offering on a pro rata basis, known as accretion rights. According to our Bylaws, in the case of a capital increase through the issuance of all four of our classes of common stock (Class A Shares, Class B Shares, Class C Shares and Class D Shares), accretion rights of the holders of each class shall be limited to the shares of the same class for which there has been no subscription. Also if, after accretion rights have been exercised within the Class B Shares and Class C Shares, there are any unsubscribed shares, such unsubscribed Class B Shares or Class C Shares may be subscribed by the shareholders of the rest of our classes of common stock, with no distinction, in proportion to the shares of common stock for which such shareholder has subscribed on such occasion. Upon the occurrence of any future increase in our Class B Shares, U.S. persons (as defined in Regulation S under the Securities Act) holding our Class B Shares underlying ADSs or ADSs may be unable to exercise preemptive and accretion rights granted to our holders of Class B Shares underlying ADSs in connection with any future issuance of our Class B Shares underlying ADSs unless a registration statement under the Securities Act is effective with respect to both the preemptive rights and the new Class B Shares underlying ADSs, or an exemption from the registration requirements of the Securities Act is available. We are not obligated to file or maintain a registration statement relating to any preemptive rights offerings with respect to Telecom Argentina’s Class B Shares underlying ADSs, and we cannot assure that we will file or maintain any such registration statement or that an exemption from registration will be available. Unless those Class B Shares underlying ADSs or ADSs are registered or an exemption from registration applies, a U.S. holder of Telecom Argentina’s Class B Shares underlying ADSs or ADSs may receive only the net proceeds from those preemptive rights and accretion rights if those rights can be assigned by the ADS depositary. If the rights cannot be sold, they will be allowed to lapse. Furthermore, the equity interest of holders of shares or ADSs located in the U.S. may be diluted proportionately upon future capital increases. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 40 Table of Contents Our status as a foreign private issuer allows us to follow alternate standards to the corporate governance standards of the NYSE, which may limit the protections afforded to investors. We are a “foreign private issuer” within the meaning of the NYSE corporate governance standards. Under NYSE rules, a foreign private issuer may elect to comply with the practices of its home country and not comply with certain corporate governance requirements applicable to U.S. companies with securities listed on the exchange. We currently follow certain Argentine practices concerning corporate governance and intend to continue to do so. For example, according to Argentine securities law, our audit committee, unlike the audit committee of a U.S. issuer, will only have an “advisory” and/or “supervisory” role, such as assisting our board of directors with the evaluation, the performance and independence of the external auditors and exercising the function of our internal control. Accordingly, holders of our ADSs will not have the same protections afforded to shareholders of U.S. companies that are subject to all of the NYSE corporate governance requirements. We are organized under the laws of Argentina and holders of the ADSs may find it difficult to enforce civil liability claims against us, our directors, officers and certain experts. We are organized under the laws of Argentina. A significant portion of our and our subsidiaries’ assets are located outside the U.S. Furthermore, almost all of our directors and officers and some advisors named in this Annual Report reside in Argentina. Investors may not be able to effect service of process within the U.S. upon such persons or to enforce against them or us in U.S. courts judgments predicated upon the civil liability provisions of the federal securities laws of the U.S. Likewise, it may also be difficult for an investor to enforce in U.S. courts judgments obtained against us or these persons in courts located in jurisdictions outside the U.S., including judgments predicated upon the civil liability provisions of the U.S. federal securities laws. It may also be difficult for an investor to bring an original action in an Argentine court predicated upon the civil liability provisions of the U.S. federal securities laws against us or these persons. In addition, a portion of our assets is not subject to attachment or foreclosure, as they are used for the performance of the public service we provide. In accordance with Argentine law, as interpreted by the Argentine courts, assets which are necessary for the provision for an essential public service may not be attached, whether preliminarily or in aid of execution. Prior to any enforcement in Argentina, a judgment issued by a U.S. court will be subject to the requirements of 517 through 519 of the Argentine Federal Civil and Commercial Procedure Code if enforcement is sought before federal courts or courts with jurisdiction in commercial matters of the Autonomous City of Buenos Aires. Those requirements are: (1) the judgment, which must be valid and final in the jurisdiction where rendered, was issued by a competent court in accordance with the Argentine principles regarding international jurisdiction and resulted from a personal action, or an in rem action with respect to personal property which was transferred to Argentine territory during or after the prosecution of the foreign action; (2) the defendant against whom enforcement of the judgment is sought was personally served with the summons and, in accordance with due process of law, was given an opportunity to defend against foreign action; (3) the judgment must be valid in the jurisdiction where rendered, and its authenticity must be established in accordance with the requirements of Argentine law; (4) the judgment does not violate the principles of public policy of Argentine law; and (5) the judgment is not contrary to a prior or simultaneous judgment of an Argentine court. Any document in a language other than Spanish, including, without limitation, the foreign judgment and other documents related thereto, requires filing with the relevant court of a duly legalized translation by a sworn public translator into the Spanish language. CVH, and through CVH, GC Dominio, have the ability to determine the outcome of any shareholder decision relating to significant matters affecting us. CVH owns Class D Shares representing 28.16% of Telecom Argentina’s total capital stock. GC Dominio owns 26.44% of the total capital stock of CVH, which represents 64.24% of the voting stock and votes of CVH. FTL owns Class A Shares representing 20.83% of the total capital stock of Telecom Argentina and, as of December 31, 2025 also owned Class B Shares in the form of ADSs representing 9.2% of total stock of Telecom Argentina. On February 10, 2026 FTL, as selling shareholder, completed a secondary offering of 4,050,549 ADSs, representing 20,252,745 Class B shares of the Company. In connection with the offering, FTL granted the underwriters a 30-day option to purchase up to 607,582 additional ADSs representing 3,037,910 Class B shares of the Company, which option was exercised in full. In the aggregate, the transaction included 23,290,655 Class B shares of the Company (representing 1.08% of Telecom Argentina’s total capital stock) and reduced FTL’s ownership interest in Telecom Argentina, in the form of ADSs accordingly. PART I - ITEM 3 KEY INFORMATION TELECOM ARGENTINA S.A. 41 Table of Contents On April 15, 2019, FTL, CVH and VLG Argentina (currently merged and absorbed by CVH) entered into the Voting Trust Agreement (as defined below) pursuant to which FTL and VLG Argentina contributed certain shares to the Voting Trust (as defined below). Except in respect of certain veto matters, the co-trustee appointed by CVH must vote all the shares contributed to the Voting Trust on all matters presented for vote generally to Telecom Argentina stockholders, in the same manner that CVH votes its shares in Telecom Argentina or as instructed by CVH. For more information about the Voting Trust, see “Item 7—Major Shareholders and Related Party Transactions—Major Shareholders—Telecom Shareholders’ Agreement.” Through its ownership of Telecom Argentina Class D Shares and pursuant to the arrangements resulting from the Telecom Shareholders’ Agreement and the Voting Trust, CVH, as a general matter, has the ability to determine the outcome of any action requiring our shareholders’ approval (except for veto matters). In addition, our bylaws provide Class A and Class D Shares, and the directors appointed by Class A and Class D Shares, with veto powers, with respect to certain matters relating to us. See “Item 7—Major Shareholders and Related Party Transactions—Major Shareholders—Telecom Shareholders’ Agreement.” We conducted transactions with the shareholders of Nortel and/or Sofora, including FTL and its affiliates in the past, and with CVH and its affiliates as of January 1, 2018. Certain decisions concerning our operations or financial structure may present conflicts between our interests and those of our shareholders. Nevertheless, all of our related-party transactions are made on an arm’s-length basis. Related-party transactions involving Telecom Argentina that exceed 1% of its shareholders’ equity are subject to a prior approval process established by Law No. 26,831, Telecom’s Bylaws and the Rules of the Executive Committee to verify that the agreement could reasonably be considered in accordance with normal and customary market practice.

INTRODUCTION The Company Telecom Argentina was created by Decree No. 60/90 of the PEN dated January 5, 1990, and incorporated as “Sociedad Licenciataria Norte S.A.” on April 23, 1990. In November 1990, its legal name was changed to “Telecom Argentina STET-France Telecom S.A.” and on February 18, 2004, it was changed to “Telecom Argentina S.A.” Telecom Argentina is organized as a corporation (sociedad anónima) under Argentine law. The duration of Telecom Argentina is 99 years from the date of registration with the IGJ (July 13, 1990). On January 1, 2018, the Merger between Telecom Argentina and Cablevisión became effective, and on such date, Telecom assumed Cablevisión’s then existing operations. On February 24, 2025, the Company acquired 86,460,983,849 common shares of TMA, representing 99.999625% of its capital stock, acquiring control, see “—Recent Developments—Acquisition of TMA.” TMA is one of the largest telecommunications and data transmission service providers in Argentina in terms of customers. TMA services in Argentina encompass mobile telephony, cable television, internet data and fixed telephony services. We are one of the largest private-sector companies in Argentina in terms of revenues, net income (loss), capital expenditures and number of employees. In terms of customers, we are one of the largest telecommunications, cable television and data transmission service providers in Argentina and one of the largest cable television services providers across Latin America. Additionally, we are an important Multiple Systems Operator (“MSO,” a company that owns multiple cable systems in different locations under the control and management of a single, common organization) in Argentina in terms of customers. We provide over 62.1 million customers with high-speed fixed and mobile connectivity, offering a flexible and dynamic digital experience across all devices, complemented by a live and on-demand content platform that integrates series, movies, music, and TV programs, and Fintech Services. We also provide data transmission and IT solutions outsourcing and we install, operate and develop cable television and data transmission services. We provide our services in Argentina (mobile, cable television, internet, fixed and data services, among others), Paraguay (mobile, internet, satellite TV services, among others), Uruguay (cable television services, internet and cybersecurity services and products), the United States (fixed and voice interconnection wholesale services) and Chile (cybersecurity services and products). In 2025, our revenues amounted to P$8,328,814 million, our net loss amounted to P$145,304 million, our Adjusted EBITDA amounted to P$2,525,535 million and we had total assets of P$16,622,552 million. For more information on the use of Adjusted EBITDA and reconciliation of net income to Adjusted EBITDA in “Item 5—Operating and Financial Review and Prospects—(A) Consolidated Results of Operations—Adjusted EBITDA.” The SEC maintains an internet site (http://www.sec.gov) that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC. Telecom Argentina’s telephone number is +54-11-5359-2752, and its principal executive offices are located in Gral. Hornos 690, (C1272ACK) Buenos Aires, Argentina.

Our authorized agent in the United States for SEC reporting purposes is Puglisi & Associates, 850 Library Avenue, Suite 204, P.O. Box 885, Newark, Delaware 19711. Subsidiaries As of December 31, 2025, Telecom Argentina’s subsidiaries were TMA, Núcleo, PEM, Cable Imagen, Televisión Dirigida and its subsidiaries, Adesol and its subsidiaries, Inter Radios, Telecom Argentina USA, Personal Smarthome and its subsidiary, Opalker and its subsidiary, Micro Fintech Holding and its subsidiaries, and TSMA. TMA is the only significant subsidiary of the Company. PART I - ITEM 4 INFORMATION ON THE COMPANY TELECOM ARGENTINA S.A. 43 Table of Contents For further information on our subsidiaries, see Note 1 to our Consolidated Financial Statements and see Exhibit 8.1 to this Annual Report. Recent Developments Acquisition of TMA On February 24, 2025 (the “Acquisition Date”), Telecom Argentina completed the acquisition of TMA for a purchase price of US$1,245 million (“consideration paid” pursuant to IFRS 3 was US$1,119 million). TMA is a company incorporated in Argentina that provides mobile and fixed telephony, fixed broadband and video services nationwide in Argentina. The purpose of the acquisition was to enhance the quality of existing services and to expand the coverage and capacity of both mobile and fixed networks. As of the date of this Annual Report, Telecom Argentina has duly and timely made all required presentations related to the acquisition of TMA and has initiated the necessary proceedings before the CNDC and ENACOM in order to obtain (i) the antitrust approval from the Secretary of Industry and Commerce (or from any succeeding enforcement authority under Law No. 27,442, as applicable) for the economic concentration resulting from the Acquisition, and (ii) the approval of ENACOM to the change of control that occurred in TMA as a consequence of the Acquisition. The filing before the CNDC was made on March 3, 2025, while the filing before ENACOM was made on March 7, 2025, both in accordance with the applicable regulatory framework. Both administrative procedures are currently underway. On March 21, 2025, the Secretary of Industry and Commerce issued the March 2025 Resolution, requiring Telecom Argentina as a provisional measure in accordance with Article 44 of Law No. 27,442 to refrain, for a period of six months or until the Secretary of Industry and Commerce issues a decision pursuant to Article 14 of Law No. 27,442 either approving or subordinating the acquisition to the fulfillment of conditions, or denying authorization of the transaction—whichever occurs first—from carrying out any legal, corporate or commercial act relating directly or indirectly to the integration or consolidation of TMA’s businesses with Telecom Argentina. This included any initiative that entails integrating TMA’s equipment with that of Telecom Argentina, as well as any exchange of competitively sensitive information with TMA, such as prices and pricing strategies, costs and margins, business plans and commercial strategies, information on customers and suppliers, investment plans, among others. Telecom Argentina must also respect the agreements regarding the reciprocal use of infrastructure previously entered into between Telecom Argentina and TMA. The Resolution does not modify the manner in which Telecom Argentina and TMA operate. As of the date of this Annual Report, TMA operates as an independent business under a separate business segment from Personal, and the members of the Board of Directors and the management of Telecom Argentina and TMA are independent of each other. On April 6, 2025, Telecom Argentina filed an appeal before the Secretary of Industry and Commerce and the CNDC against the Resolution No. 63/2025, as well as against the note from the Secretary of Industry and Commerce dated March 27, 2025 to the CNDC appointing a monitoring agent for the Telecom Argentina and TMA to oversee compliance with the measure. On June 5, 2025, Telecom Argentina was notified of the decision issued by Chamber III of the Federal Civil and Commercial Court of Appeals, which granted the appeal with suspensive effect and ordered the Secretary of Industry and Commerce to refrain from adopting any measure that would contravene the suspensive effect with which the appeal was granted. In addition, on June 19, 2025, Telecom Argentina was notified of a resolution by the Secretary of Industry and Commerce that included (i) a statement of objection to the transaction; (ii) a request for Telecom Argentina to present its arguments against the objections within 15 days, and (iii) a call for a special hearing to consider the measures proposed by Telecom Argentina to overcome these objections. This resolution does not represent a final resolution or the imposition of penalties, but rather a procedural stage affording the parties the opportunity to exercise their right of defense, submit responses, or propose commitments to mitigate potential anticompetitive effects. PART I - ITEM 4 INFORMATION ON THE COMPANY TELECOM ARGENTINA S.A. 44 Table of Contents Telecom Argentina believes that the aforementioned objection report was issued and notified prematurely, at an early stage of the process, without all the necessary information being considered and before all relevant procedures established under the antitrust laws were completed. In this regard, Telecom Argentina does not agree with the preliminary conclusions expressed in the objection report and has focused on analyzing all CNDC statements therein and submitting all appropriate presentations and technical data in response to the report (including Form F-2 as required by antitrust law, which was submitted by Telecom Argentina on June 29, 2025) to advance the review process and obtain the relevant approvals. On August 5, 2025, Telecom Argentina duly and timely submitted its response to the preliminary objection report issued by the CNDC. Together with that submission, and without this being construed in any way as an acknowledgment that the transaction raises an antitrust concern, Telecom Argentina expressed its willingness, as a procedural safeguard contemplated under Law No. 27,442, to consider potential commitments to address the provisional concerns outlined in the objection report, should the authorities deem it necessary. Telecom Argentina believes that any such potential commitments, if required, would be limited, proportionate, and would not have a material adverse effect on Telecom Argentina’s business, financial condition, or ability to meet its financial obligations. Subsequently, the CNDC held the special hearing provided for in Article 14 of Law No. 27,442. The first hearing took place on September 19, 2025, and the second hearing on October 6, 2025, at which time the CNDC decided to adjourn the proceedings, leaving their continuation subject to the CNDC’s evaluation of the observations and submissions previously made by Telecom Argentina, as well as of the information still pending submission by third parties at the CNDC’s request. On November 17, 2025, pursuant to Decree No. 810/2025, the Argentine government established the Argentine National Competition Authority (Autoridad Nacional de Competencia) (the “ANC”), a decentralized and autonomous entity that replaced the CNDC. The ANC became operational upon the appointment of its authorities in accordance with Law No. 27,442, which designates the ANC as the body responsible for protecting and promoting competition and safeguarding the general economic interest. As a result, the regulatory review of the Acquisition is conducted under the supervision of the ANC. On December 23, 2025, Chamber III of the National Court of Appeals in Civil and Commercial Matters issued its decision regarding the appeal filed by Telecom Argentina against Resolution No. 63/2025 of the Secretary of Industry and Commerce. The Court held that ruling on the appeal had become moot, given that at the time the judgment was rendered, the precautionary measure had already expired. In this regard, the Chamber expressly stated that no evidence had been submitted in the case file demonstrating an extension of the precautionary measure and therefore concluded that there was no longer an existing case or controversy that would warrant consideration of the appeal. The Argentine Government filed a Federal Extraordinary Appeal against this resolution, which has been notified to Telecom Argentina on February 23, 2026. Telecom Argentina has duly responded within the established timeframe, requesting that the appeal be dismissed as inadmissible. Likewise, on that same date, a new hearing was held within the framework of the procedure established in Article 14 of Law No. 27,442 before the ANC, which constituted a continuation of the previously mentioned hearings. With this hearing, the hearing stage contemplated by the procedure was deemed concluded, leaving the case under review by the ANC for the issuance of the corresponding resolution within the framework of the operation’s review process. Telecom Argentina will exercise all rights available to it to review or challenge any decisions that it considers to be inconsistent with applicable Argentine law or the actual competitive conditions in each relevant market and jurisdiction. Although there can be no assurance regarding the outcome of the post-closing review of the Acquisition by regulatory authorities, Telecom Argentina and its legal advisors have arguments to support the its position. PART I - ITEM 4 INFORMATION ON THE COMPANY TELECOM ARGENTINA S.A. 45 Table of Contents Acquisition Financing The Acquisition was financed by Telecom Argentina through the Existing Loans totaling US$1,170 million: ● An unsecured syndicated loan granted by Banco Bilbao Vizcaya Argentaria S.A., Deutsche Bank AG, London Branch and Banco Santander, S.A., governed by New York law (the “Syndicated Loan”); and ● An unsecured bilateral loan granted by Industrial and Commercial Bank of China (Argentina) S.A.U., governed by Argentine law (the “Bilateral Loan”). On May 28, 2025, we issued US$800 million in aggregate principal amount of 9.250% senior notes due 2033 (the “2033 Notes”) in the international markets pursuant to Rule 144A and Regulation S of the Securities Act. We applied the proceeds from the 2033 Notes to (i) partially prepay the Syndicated Loan in a principal amount equal to US$650.3 million, reducing the outstanding principal amount thereunder to US$319.7 million, and (ii) partially prepay the Bilateral Loan in a principal amount equal to US$134.1 million, reducing the outstanding principal amount thereunder to US$65.9 million. On June 24, 2025, we issued an additional US$200 million in aggregate principal amount of 2033 Notes. Following such issuance, the aggregate principal amount of outstanding 2033 Notes increased to US$1,000 million. We applied the proceeds from the reopening to partially prepay the Syndicated Loan in a principal amount equal to US$168.8 million, reducing the outstanding principal amount thereunder to US$150.9 million, and to prepay the Bilateral Loan in a principal amount equal to US$34.8 million, reducing the outstanding principal amount thereunder to US$31.1 million. On January 20, 2026, we applied the proceeds from the Notes described below under “Debt Transactions” to fully prepay the Existing Loans. For further information about our borrowing, see Note 14 of our Consolidated Financial Statements and “Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Borrowings Developments during 2025.” Debt Transactions On January 20, 2026, we issued US$600 million in aggregate principal amount of US$600 million 8.5% senior amortizing notes due 2036 (the “2036 Notes”) in the international markets pursuant to Rule 144A and Regulation S of the Securities Act. We applied the proceeds from the 2036 Notes to (i) prepay in full the Existing Loans (principal amount outstanding of US$182 million plus accrued interest), and (ii) redeem in full our outstanding 8.000% Senior Notes due 2026, at a redemption price of US$164 million, plus accrued interest. On March 5, 2026, we issued US$81 million aggregate principal amount of our 6.50% fixed rate notes due 2029 (the “Series 28 Notes”) in the Argentine local capital markets. The Series 28 Notes were issued at an issue price of 100% of their principal amount and will mature on March 5, 2029. The Series 28 Notes accrues interest at a fixed nominal annual rate of 6.50% and is payable semi-annually. Changes in Senior Management On July 3, 2025, Telecom Argentina’s Chief Financial Officer, Gabriel Blasi, informed the Board of his intention to retire from his position during the last quarter of 2025. This decision was made strictly for personal reasons and in full agreement with the Company. During the interim period prior to his departure and as of the date of this Annual Report, Telecom Argentina is considering a succession plan to ensure the continuity and quality of its management. Pending completion of this process, the duties of Chief Financial Officer will be performed on an interim basis by Telecom Argentina’s Director of Finance, Federico Pra as of December 23, 2025. PART I - ITEM 4 INFORMATION ON THE COMPANY TELECOM ARGENTINA S.A. 46 Table of Contents Agreement between Telecom Argentina, Micro Fintech Holding and Micro Sistemas with Banco Macro S.A. On January 22, 2026, Telecom Argentina and its direct and indirect subsidiaries Micro Fintech Holding and Micro Sistemas entered into a framework agreement with Banco Macro S.A. (“Banco Macro”) aimed at fostering the growth and expansion of the business of Micro Sistemas, a payment services provider operating under the “Personal Pay” brand. This strategic alliance will enable the development of a differentiated and comprehensive value proposition for customers operating on the “Personal Pay” platform, while also expanding the range of financial products and services offered to a broader customer base, supported by Banco Macro’s leading position in the financial sector. For these purposes, Banco Macro will contribute its expertise in financial products, while Micro Sistemas will contribute its extensive base of active customers and recurring use cases with genuine transaction activity, thereby promoting a more efficient and broader market with customers at its core. Pursuant to this agreement, Banco Macro made a capital contribution and, therefore, subscribed for shares representing 50% of the share capital and voting rights of Micro Sistemas, for an amount in pesos equivalent to US$75 million. As a result of this transaction, the Company no longer holds the majority of the voting rights required to exercise control over Micro Sistemas and, accordingly, the Company now has joint control over such entity. The transaction is subject to the corresponding approval by the National Antitrust Authority, in accordance with applicable regulations. PART I - ITEM 4 INFORMATION ON THE COMPANY TELECOM ARGENTINA S.A. 47 Table of Contents THE BUSINESS The Executive Committee and the CEO have a strategic and operational vision of Telecom as a single business unit. This reflects the current regulatory context of the converged ICT Services industry, under which mobile services, internet services, cable television and fixed and data services, are all governed by the same regulatory framework and therefore consolidated into a single segment. To exercise their functions, both the Executive Committee and the CEO periodically receive the economic-financial information of Telecom Argentina and its subsidiaries located in Argentina except TMA (stated in historic currency at the transaction date) prepared as a single segment and evaluate the evolution of the business as a single results-generating unit, administrating the resources in a unique way to achieve the objectives. Costs are not specifically allocated to a type of service, as Telecom Argentina has a single payroll and operating expenses that affect all services in general. Further, decisions on capital expenditures affect all types of services provided by Telecom Argentina and its subsidiaries in Argentina except TMA and are not allocated specifically to one of them. Following the Acquisition, dated February 24, 2025, the Company identified a new reportable segment, “ICT Services provided in Argentina – TMA Network” corresponding to the provision of mobile and fixed telephony services, fixed broadband, and video services on a nationwide scale in Argentina, using TMA’s own networks, with its own infrastructure. See “—Recent Developments—Acquisition of TMA.” TMA is managed as a separate business unit, and therefore, the Executive Committee and the CEO review its economic and financial information (stated in historic currency at the transaction date) separately. Costs are not specifically allocated to a type of service, as TMA has a single payroll and operating expenses that affect all services in general. Further, decisions on capital expenditures affect all types of services provided by TMA and are not allocated specifically to one of them. Additionally, Telecom, through Micro Sistemas, develops activities in the fintech industry in Argentina. Telecom also carries out activities abroad (Paraguay, USA, Uruguay and Chile). The operations that Telecom develops through Micro Sistemas, and those developed abroad, are not analyzed as a separate segment by the Executive Committee and the CEO, considering that they are not considered as individually significant. These operations do not meet the aggregation criteria established by the standard to be grouped within the “ICT Services provided in Argentina– Personal Network” segment and considering that they do not exceed any of the quantitative thresholds identified in the standard to qualify as reportable segments, they are grouped within the category “Other segments.” As a result, segments as of December 31, 2025, are the following: ● ICT Services provided in Argentina – Personal Network: Corresponds to the operations carried out by Telecom Argentina and its subsidiaries located in Argentina (excluding TMA) engaged in the provision of ICT services. ● ICT Services provided in Argentina – TMA Network: Corresponds to the operations carried out by the subsidiary TMA as from the acquisition date. ● Other segments: Corresponds to the operations for a) ICT services provided abroad (Paraguay, USA, Uruguay and Chile) and b) the development of activities in the fintech industry, through the subsidiaries Micro Sistemas in Argentina and Personal Envíos and CrediPay in Paraguay. The Executive Committee and the CEO evaluate the profitability for each reportable segment based on the measure of the Adjusted EBITDA. Adjusted EBITDA is defined as our net (loss) income less income tax, financial results, earnings (losses) from associates and joint ventures, and depreciation, amortization and impairment of Fixed and Intangible Assets, reviewing this information in the currency of the date of each transaction. For a breakdown of total revenues by category of activity, please see “Item 5—Operating and Financial Review and Prospects.” For more information, see Note 1.b) of our Consolidated Financial Statements. Main Products and Services We offer our customers an ecosystem of services and platforms, leveraged by robust connectivity inside and outside the home, along with the best entertainment experiences, and technological solutions for people, startups, industries and governments. PART I - ITEM 4 INFORMATION ON THE COMPANY TELECOM ARGENTINA S.A. 48 Table of Contents To achieve this, we use the latest technologies available for our networks, systems, and business models, partnering with renowned global companies. Our focus remains on expanding and enhancing our fixed and mobile networks, as well as increasing Broadband coverage and capacity. We are also pursuing new business opportunities through a digital platform and marketplace development model that allows us to maximize opportunities across the region. We extend our footprint to other markets, with new businesses based on the development of APIs and applications, highlighting our infrastructure and network capabilities for developers around the world. In line with our vision of innovation and diversification, we explore new business opportunities and seek to go beyond connectivity and accompany the challenges of the digital economy. We intend to become a relevant player in the Latin American financial industry by developing products that generate monetization in the digital ecosystem, leveraging 5G and positioning ourselves regionally. With new businesses such as IoT, Fintech Services, cybersecurity, entertainment, OpenXpand and smart home, among others, we are committed to constant innovation to offer comprehensive solutions and adapt to changing market demands. As of December 31, 2025, we offered our customers a diverse range of services, which are presented below and categorized by reportable segment: Ø ICT Services provided in Argentina – Personal Network Toward the end of 2025, we took a decisive step in our company’s evolution by unifying our brand identity with a core conviction: to streamline, simplify, and scale our value proposition to support the digital needs of individuals, households, and organizations across the country. Since December 2025, Personal has been consolidated as the brand that integrates our entire ecosystem of services. With this new architecture, all our solutions are consolidated under a single identity: Personal Móvil and Personal Fibra guarantee mobile and fixed connectivity with cutting-edge technology; Personal Flow enhances the entertainment experience with live TV and on-demand content; Personal Pay provides simple and secure digital financial solutions; Personal Smarthome and Tienda Personal expand access to affordable smart home solutions; and Personal Tech supports businesses, organizations, and governments in their digital transformation processes. This rebranding positions Personal for the future with a clear vision: to lead the country’s digital ecosystem through integrated, simple, and people-centered experiences. Brand: Personal Móvil Personal Fibra Personal Flow Personal Pay Tienda Personal Personal Smarthome Personal Tech Services Mobile Telecommunications Services Internet Services Cable Television Services Fintech Services (a) Smart home solutions. Cybersecurity, cloud, IoT, datacenter and infrastructure (a) These services are not included as part of the segment “ICT Services provided in Argentina – Personal Network,” and are aggregated in “Others segments.” In January 2026, Banco Macro subscribed for shares representing 50% of the share capital and voting rights of Micro Sistemas, see “—Information on the Company—Recent Developments—Agreement between Telecom Argentina, Micro Fintech Holding and Micro Sistemas with Banco Macro S.A.” ●Mobile Telecommunications Services Overview Mobile telecommunications service offerings include voice communications, high-speed mobile internet content and applications download and online streaming, among others, as well as the sale of mobile communication devices (handsets, Modems MiFi and wingles, smart watches). The services are supported by the different technologies of the mobile network (4G/5G). PART I - ITEM 4 INFORMATION ON THE COMPANY TELECOM ARGENTINA S.A. 49 Table of Contents As of December 31, 2025, we had approximately 19.9 million mobile customers, consisting of 60% prepaid customers and 40% postpaid customers. We provide mobile services on 850 MHz in the Northern Region and AMBA, 1,900 MHz, 700 MHz and AWS (paired frequencies in 1,700 MHz and 2,100 MHz) in the whole country and 900 MHz and 2,600 MHz assigned by towns and cities. Additionally, we provide 3,500 MHz in the whole country for 5G services. During 2025, Personal Movil expanded its 5G footprint by adding 819 new sites, reaching a total of 1,084 by the end of the year. In addition, the number of customers with 5G-enabled devices was 3.5 million by year-end. Residential and Corporate Services We offer mobile telecommunication services to residential and corporate customers through a variety of flexible options. These options include prepaid, post-paid and “Abono Fijo” (fixed subscription plans). ● Prepaid Plans. Under prepaid plans, customers pay in advance for services, using prepaid credit. Since there are no monthly bills, prepaid plans allow customers to communicate with maximum flexibility while maintaining control over their consumption. Prepaid credit can be purchased through prepaid cards or virtual credit on our website, by phone, at ATMs and drugstores, or through authorized agents. Our mobile telecommunication customers may browse the internet, make and receive local, national and international calls and buy multimedia content. We offer a variety of “packs” which enable customers to use the abovementioned services at lower prices. These packs may include a fixed number of minutes to make national or international calls, SMSs, and a quota of megabytes for browsing the internet, among other services. ● Post-Paid Plans. Under post-paid plans, customers pay a monthly fee for a particular plan, plus charges for additional services not included in that plan. Most of the plans we offer include a quota of megabytes for browsing the internet and unlimited airtime for on-network calls and SMS. Depending on the price, some plans include a number of free seconds or unlimited airtime for off-network calls. Once the included seconds have been used, customers can continue using the mobile service at a set price per second. Customers can also purchase additional megabytes to continue browsing the internet after using the megabytes included in their monthly plan. Charges for additional airtime, megabytes or multimedia content are added to the following month’s bill. These plans also include gigabytes or roaming minutes to communicate abroad. Among the post-paid plans, we also offer M2M plans based on the IoT concept, which refers to the digital interconnection of everyday objects to the internet, and are specifically aimed at business customers. These plans include solutions such as geolocation and fleet monitoring, refrigeration control, information security solutions, sales management solutions, and cloud solutions for information storage and protection. ● Fixed Subscription (Abono Fijo). Under the Fixed Subscription (Abono Fijo) plans, a customer pays a set monthly bill. As in post-paid plans, most of these plans include a quota of megabytes for browsing the internet, unlimited airtime for on-net and off-net calls, SMS and a fixed amount of credit that can be used to buy packs or multimedia contents. Once the prepaid seconds have been used or the internet quota has been met, the subscriber can obtain additional credit by recharging its line through the prepaid system. Our strategy during 2025 focused on continuing to lead in mobile services, promoting the consumption of high-speed services by providing upgrades and improving the experiences of certain customers, and more generally addressing the needs of small, medium and large customers and continuing to grow in the Digital Solutions business (Cloud & Infrastructure, Datacenter, Cybersecurity and IoT). In addition, we worked on strengthening the value proposition of our mobile products by renewing all aspects related to the management of gigas included in customer plans and introducing new benefits, such as higher gigas allowances, automatic gigas doubling for convergent customers, gigas sharing across lines, and the Video Pass benefit, which allows streaming videos and Flow content with 5G connectivity without consuming gigas from the plan. These initiatives aimed to deliver greater value, flexibility, and a superior experience. PART I - ITEM 4 INFORMATION ON THE COMPANY TELECOM ARGENTINA S.A. 50 Table of Contents The main developments in our residential and corporate services during 2025 were the following: ● we continued offering mobile services ranging from prepaid plans to postpaid plans, and between four gigabytes and 50 gigabytes for residential and corporate services; ● we continued focusing on the development of convergent offers for our customers, offering additional bonuses upon the purchase of various services, to increase customer loyalty. We extended the initiative to corporate customers, seeking to increase services convergence; ● we continued adding benefits for mobile and convergent subscription customers; ● we focused on expanding international service capabilities, reinforcing coverage and technologies and improving performance metrics to ensure superior quality and customer experience. These efforts were complemented by initiatives to optimize traffic management and control costs, supporting the evolution of our roaming offer and maximizing data benefits. As a result, 80% of our customers used our international roaming service when traveling abroad; and ● we prioritized the development of 5G Roaming and VoLTE Roaming to enhance data and voice experiences, achieving coverage across 61 countries—ensuring that more than 80% of our customers travel to destinations where this technologies are available. These actions allowed us to consolidate the best market experience, reflected in an NPS above 50 points. Wholesale Services Our mobile telecommunications infrastructure also enables us to offer a range of wholesale services, as summarized below. ● International Business. During 2025, inbound international visitors to Argentina declined by 19.7%; however, revenue from inbound roaming increased by 15.7% driven by new roaming agreements, the retention of existing agreements, and improved commercial terms. We continued focusing on reducing outbound traffic costs. In 2025, the number of Data Roamers (mobile subscribers who consume mobile data services while accessing a visited network outside the coverage area of their home operator, either under national or international roaming agreements - these users generate data traffic on third‑party networks pursuant to inter‑operator roaming arrangements, regardless of the underlying service plan or the amount of data consumed) grew by 54% and total outbound traffic increased by 86%, reinforcing the importance of continually improving our commercial agreements to sustain margins. With respect to our SMS A2P business, traffic declined by 6%. Nevertheless, revenues decreased by only 4%, supported by the reactivation of domestic SMS A2P activity, which helped mitigate the impact of reduced volumes. We initiated the monetization of our network capabilities through aggregator facilitated services, generating new revenues from the launch of our first standardized API — SIM Swap validation. With the subsequent rollout of five additional APIs, we consider this an emerging business line with significant potential and expect it to become a relevant contributor to future revenue streams. ● Domestic Business. revenues and costs mainly related to interconnection traffic charges (call origination/termination, long distance transport and transit, both on the mobile network and on the fixed network); sale of interconnection service resources, sale of infrastructure to Large Groups (such as Datacenter Services, Mobile Backhaul, Links, etc.), national roaming, and infrastructure sharing (including RAN sharing and lease of conventional and non-conventional sites, among others). PART I - ITEM 4 INFORMATION ON THE COMPANY TELECOM ARGENTINA S.A. 51 Table of Contents Network and Equipment In terms of infrastructure, during 2025 we continued to improve the services we provide by deploying the 4G/LTE network and the deployment of fiber optics to connect homes with Broadband, which also had an impact on fixed and data network. This allowed us to stand out from our competitors, significantly improving the NPS of our customers. The deployment of 4G/LTE has achieved a coverage of 97% of the urban population in more than 2,245 towns and cities as of December 31, 2025. Furthermore, we have reached a 98% coverage of the population in major cities of Argentina, as of December 31, 2025. Customers who access our 4G network experience enhanced service quality, enjoying speeds of up to 84 Mbps and, approximately 85% of calls are now made using VoLTE, a technology that enables voice calls over the 4G network, resulting in significant improvements in audio and video quality. In addition, we have continued the deployment of mobile site connectivity to enhance quality and capacity, replacing radio links with high-capacity fiber optic connections. Furthermore, the initiative to connect remote and low-density areas through satellite backhaul remains ongoing. Regarding 5G, by the end of 2023, and through the Argentine government-launched tender, we have acquired spectrum that will accelerate the growth of our 5G service. Currently, we have reached 1,084 sites with 5G. Competition The market for residential, corporate and wholesale mobile telecommunications services in Argentina is characterized by intense competition. Operators are free from regulation to determine the pricing of services, except that ENACOM sets prices for wholesale local interconnection services. During 2025, three mobile operators offered nationwide service: Personal, TMA and AMX Argentina. ● Internet Services Overview We provide Broadband internet services with Personal Fibra brand. Broadband can be delivered through three technologies: cable modem (HFC), fiber optic (FTTC and FTTH - and dedicated for corporate services-) and wireless (and satellite for corporate services); being cable Modem and FTTH the most widely used for residential services. We market our services through HFC and FTTH technologies. During 2025, such services provide speeds for up from 100 MB to 1,000 MB During 2025, our home products strategy focused on accelerating migrations to our preferred fiber network, offering in-home coverage solutions, and providing more options to ensure service continuity. In addition, we continued promoting Broadband offers by delivering higher speeds to customers with technical availability. Our strategy for access networks aimed to meet the growing demand for Broadband, mainly driven by video and multimedia content consumption. To achieve this, we continued expanding our fiber optic access infrastructure through different modalities and technologies, optimized according to service demand and geographic location. During 2025, we continued deploying our FTTH network both in greenfield areas (an area where we have not deployed any of our technology networks: HFC or FTTH) and in the reconversion of brownfield areas (an area where we have network deployment), granting more customers access to ultra-high internet velocity with speeds of 1,000 MB and also upgrading the customer base average speed by migrating customers to our HFC and FTTH network (i.e., technologies that replace copper with fiber optics in different points of the transmission network). As of December 31, 2025, the number of customers with access to FTTH technology grew 37% compared to December 31, 2024. In May 2025, we introduced our new Fixed Wireless Access (FWA) product, a technological solution that provides broadband connectivity through mobile networks. The goal of this launch is to bring high-speed internet to areas where fiber optic has not yet reached, expanding our coverage, ensuring that more communities can access quality services, and reducing the digital divide. This product also enables us to offer customers internet service in areas where obsolete networks have been shut down. PART I - ITEM 4 INFORMATION ON THE COMPANY TELECOM ARGENTINA S.A. 52 Table of Contents Finally, we also added Wi-Fi signal extenders to our portfolio, designed to ensure coverage in every corner of the home. This product directly addresses the need expressed by our customers who experienced connectivity issues in certain areas. The extenders are available in our online store and can also be offered by our technical service during home visits, ensuring that every customer enjoys a stable and high-quality connection experience. Residential and Corporate Services As of December 31, 2025, we had approximately 4.2 million internet customers. During 2025, we continued with the reconversion of Personal Fibra’s fixed internet network, expanding in 2025 by 17,000 FTTH blocks in new locations and/or XDSL / HFC one way and 16,000 FTTH blocks in HFC two-way (Overlay) areas. Key projects included completing FTTH coverage in the main capitals and major cities across the northern region, consolidating our footprint in strategic areas. Additionally, the overlay strategy aimed to accelerate the migration from HFC to FTTH in the largest urban centers, including CABA, AMBA, Rosario, and Córdoba. The migration of customers towards the best available technology (XDSL to HFC/FTTH and HFC to FTTH) and the selective shutdown of obsolete networks continued, seeking efficiency and improving customer service. The internet connectivity products we offer through the Personal Fibra brand are specially tailored to the needs of each residential or corporate user and include specific solutions such as virtual private network services, traditional IP links and corporate products that offer additional services. We offer internet products ranging from 100MB to 1,000 MB. Customers with a service of 100 MB or more represent 98% and 89% of the total customer base as of December 31, 2025, and 2024, respectively. Within this range, customers have contracted service plans of 100 MB, 300 MB, 600 MB and 1,000 MB which, as of December 31, 2025, amount to 1.4 million, 2.2 million, 0.2 million and 0.1 million, respectively, positioning our Personal Fibra brand as the technological benchmark brand of the industry. Additionally, we offer international IP access through well-known global Backbone providers. We also offer Personal Wifi Zone, a connectivity experience available to our customers with Personal Fibra internet at home, which is the largest WiFi network in Argentina. Personal WiFi Zone currently has a coverage of more than 2.4 million locations distributed throughout the country. The service is used by 180 thousand customers on a monthly basis. Network and Equipment In order to continue bringing fiber optics closer to customers, we consolidated the deployment of FTTH networks, substantially improving the possibility of offering high-speed services. This rollout encompassed both residential and corporate customers, new neighborhoods, gated communities, buildings, and shopping malls. With respect to HFC networks, investments were focused on increasing the capacity of existing networks to keep up with our customers’ traffic demand by reducing service areas and increasing upstream capacity. In addition, the deployment of a new FTTH network superimposed on the HFC network continued, seeking to connect the new customers to this new network. In this way, the traffic on the HFC network is relieved, and better services are provided to our customers. In addition to the renewal of the access network described above, the transformation process of the transport network continued, allowing not only greater capacity, but also greater operational efficiency and scalability. PART I - ITEM 4 INFORMATION ON THE COMPANY TELECOM ARGENTINA S.A. 53 Table of Contents Competition In Argentina, the internet service market includes operators such as TMA, AMX Argentina, Gigared and Telecentro (providing a triple-play offer), as well as satellite-based broadband services such as Starlink, which may compete in certain customer segments, particularly in regions with lower population density or limited access to fixed broadband infrastructure. During 2025, AMX Argentina continued its investments for the construction of their fixed FTTH networks, increasing its penetration and ability to serve households in different areas of the country. The data services business includes providers such as AMX Argentina and several providers of niche data services such as Cirion Technologies, IPlan, Metrotel and others. ● Cable Television Services Overview We provide cable television services in different locations in Argentina. Through Personal Flow, the Company seeks to consolidate itself as an “entertainment meeting point,” offering access to a platform with live and on-demand content.

Through these networks, we offer additional revenue-generating services and products, such as premium services and pay-per-view. As of December 31, 2025, we had approximately 3.3 million cable television customers, which represented a 37% of the Argentine market share for cable television services. Our Cable Television Networks and Operating Regions As of December 31, 2025, our principal cable networks were located in AMBA. We also operated cable networks in other cities within the provinces of Buenos Aires, Santa Fe, Entre Ríos, Córdoba, Corrientes, Formosa, Misiones, Salta, Chaco, Neuquén, Río Negro, Mendoza, Tucumán and San Juan. As of December 31, 2025, Personal Flow’s fiber optic network covered approximately 98,000 kilometers, of which approximately 35,000 kilometers correspond to the interurban network. Retail and Corporate Programming and Other Cable Television Services In 2025, we continued investing significant resources to expand the variety of programming options in order to appeal to potential new customers and meet their needs. Our cable television services revenues are derived primarily from monthly subscription fees for cable service. To a lesser extent, our cable television services revenues also derived from connection fees and advertising and fees for premium and pay-per-view programming services, Flow, and video-on-demand services (“VOD”). We purchase basic and premium programming from more than 100 signal providers in Argentina. Programming arrangements are primarily denominated in Argentine Pesos. Fees paid to signal providers under these arrangements are linked to the growth of our cable television subscriber base and the fees charged. PART I - ITEM 4 INFORMATION ON THE COMPANY TELECOM ARGENTINA S.A. 54 Table of Contents Premium Services (Premium Packages) Our customers are given the option to acquire Premium Packages not included in the basic package by paying an additional fee. These packages and services include channels in addition to those included in the basic package, provide exclusive content, and divide such content by movie genres and sports, or a combination of these categories.

Competition In Argentina, with respect to cable television transmission, we face competition from other cable television operators and providers of other television services, including direct broadcasting, satellite and wireless transmission services. As a result of the non-exclusive nature of our licenses, our cable systems frequently have been overbuilt by one or more competing cable networks, in addition to the satellite television service that is also available. Free broadcasting services are currently available in Argentina. In the AMBA, these services primarily include four privately-owned channels and their local affiliates, and one state-owned national public television network. Paid television industry is highly fragmented, and our largest competitors are Telecentro S.A., which is focused in the AMBA, and DirecTV Argentina S.A. (“DirecTV”) (satellite television), present throughout the entire country. In addition, AMX Argentina consolidated its offer of video products together with fixed Broadband, in the context of the development of their fixed network.

PART I - ITEM 4 INFORMATION ON THE COMPANY TELECOM ARGENTINA S.A. 79 Table of Contents DISCLOSURE PURSUANT TO SECTION 219 OF THE IRAN THREAT REDUCTION AND SYRIA HUMAN RIGHTS ACT OF 2012 (ITRSHRA) Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 added Section 13(r) to the Exchange Act, which requires a 34’ Exchange Act registrant to disclose in its annual or quarterly reports furnished to the SEC whether the issuer or any of its affiliates has knowingly engaged in certain activities, transactions or dealings with the government of Iran, relating to Iran or with designated natural persons or entities involved in terrorism or the proliferation of weapons of mass destruction during the period covered by the annual or quarterly report. Disclosure is required even when the activities were conducted outside the United States by non-U.S. entities and even when such activities were conducted in compliance with applicable law. In accordance with our Code of Ethics and Conduct, we seek to comply with all applicable laws. Activities relating to Iran Commercial Agreements with International Carriers (fixed services): During 2025, we have provided international telecommunications services agreements with international carriers (fixed services), which cover delivery of traffic to Iran through non-Iranian carriers. We maintain commercial agreements with international carriers located in countries other than Iran, which permit those carriers to deliver traffic from Iran to our networks and from our networks to Iran. Our total expenses under commercial agreements with international carriers regarding delivery of traffic to Iran were approximately US$66.22 as of December 31, 2025. During 2025, and regarding outgoing traffic, we have sent traffic to Iran only through Telecom Italia Sparkle S.p.A (Italy). Regarding incoming traffic, we charge the relevant international carrier for traffic ending in our network. Consequently, we do not know the country of origin of such traffic. Accordingly, our total payables and receivables from international carriers include balances arising from traffic related to Iran but it is not possible to segregate them. The outbound costs are wholly immaterial with respect to the Company’s consolidated operating expenses for the period presented.

Our total capital expenditures were P$1,485,577 million in 2025, P$748,974 million in 2024 and P$1,384,193 million in 2023, and represented 17.8%, 13.8% and 23.5% of our consolidated revenues, respectively. We estimate that our capital expenditures in 2026 will be approximately P$1,349,643 million for ICT services provided in Argentina – Personal Network, P$641,367 million for ICT services provided in Argentina – TMA Network, and P$120,075 million for other segments. See “Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Capital Expenditures.” We expect to finance these expenditures through cash flows generated by our operations and financing provided by third parties. PP&E As detailed below, our principal physical properties consist of transmission equipment, access facilities, outside plant (external wiring) and switching equipment. These assets are, at present, mainly located throughout AMBA, the Northern Region and the Southern Region. Some of our assets are located in areas that may be subject to natural disasters and severe weather, and which may be adversely affected in the future by climate change.

Our Consolidated Financial Statements have been prepared in accordance with IFRS Accounting Standards as issued by the IASB. The following discussion and analysis are presented by the Management of our company and provide a view of our financial condition, operating performance and prospects from the Management’s perspective. The strategies and expectations referred to in this discussion are considered forward-looking statements and may be strongly influenced or changed by shifts in market conditions, new initiatives that we implement and other factors. Since much of this discussion is forward-looking, you are urged to review carefully the factors referenced elsewhere in this Annual Report that may have a significant influence on the outcome of such forward-looking statements. We cannot provide assurance that the strategies and expectations referred to in this discussion will come to fruition. Forward-looking statements are based on current plans, estimates and projections, and therefore, you should not rely solely on them. Forward-looking statements speak only as of the date they are made, and we undertake no obligation to update any forward-looking statements in light of new information or future events. Forward-looking statements involve inherent risks and uncertainties, most of which are difficult to predict and are generally beyond our control. We caution you that a number of important factors could cause actual results or outcomes to differ materially from those expressed in, or implied by, the forward-looking statements. Please refer to “Forward-Looking Statements,” “Item 3—Key Information—Risk Factors” and “—Trend Information” below for descriptions of some of the factors relevant to this discussion and other forward-looking statements in this Annual Report. Management Overview We operate with a global vision, integrating sustainability into every aspect of our business. We firmly believe in the transformative power of technology, as it supports the digital lives of individuals and organizations and evolves in alignment with social and environmental demands, contributing to an increasingly sustainable future. We continue to advance our business strategy, with a focus on the digital evolution of society, strengthening our position as a technology company with regional scale. This is reflected in the ecosystem of digital products, services, and solutions that we offer to our customers. Our commitment to digitalization drives continuous innovation. We have adopted collaborative and efficient ways of working that strengthen our management practices and foster the development of our workforce community. Thousands of people make this transformation possible through their talent, creativity, and commitment, contributing every day to the development of a more dynamic company that is well positioned for the future. One of the most significant milestones of the year was the acquisition of TMA, completed on February 24, for a contractual purchase price of US$1,245 million (“consideration paid” pursuant to IFRS 3 was US$1,119 million). This acquisition was carried out as part of the Company’s expansion plan, which includes the deployment and densification of fiber-optic networks, 5G mobile sites, and value-added services. This transaction reinforces our long-term vision and our commitment to the development of strategic infrastructure supporting the digital economy in the country and the region. In a global context of transformation and consolidation across the industry, this investment represents a decisive step toward strengthening our capabilities, achieving greater scale, and generating synergies that support the long-term sustainability of our business. We continue to evolve our value proposition for the B2B business by offering tailored and scalable solutions to our enterprise customers, supported by a portfolio built on key technological pillars: fixed and mobile connectivity, cybersecurity, cloud solutions, and IoT. We continued to advance the extension of Argentina’s 5G network, which strengthens our connectivity infrastructure and underscores our commitment to the digital development of the country and its future opportunities. At the same time, we continued the deployment of FTTH technology across various cities in Argentina. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 83 Table of Contents Along this path, we received a new recognition from Ookla, which underscores the superior performance of the Personal Network across the attributes most valued by users, as the fastest mobile network through Personal Fibra in Argentina. We continued to further develop OpenXpand, a digital platform designed to promote the adoption of Open Gateway across Latin America and reinforces us as a technological leader at the regional level, by offering digital, secure, and scalable solutions. With respect to our environmental commitment, during the year we adopted short-term decarbonization targets that were validated by the international Science Based Targets initiative (SBTi), aligned with our commitment to achieve carbon neutrality by 2050. Energy efficiency, driven by our use of technologies such as cloudification, virtualization, AI, and automation, along with an increase in renewable energy supply, are some of the practices we have developed. Additionally, we have made progress in circular economy initiatives and cleantech solutions. The year 2025 presented significant challenges, particularly in terms of financial sustainability. We obtained bank loans totaling US$1,170 million, the proceeds of which were used to finance the acquisition of TMA. Through the issuance of Notes, we were able to refinance those loans and repay other obligations, thereby improving our financial costs. We issued Notes for an aggregate principal amount of US$1,051 million and P$58,000 million, which enabled us to repay and refinance a portion of our loans, improving terms and financing costs. Additionally, during 2025, we distributed dividends for an aggregate of P$220,482 million (P$226,756 million in current currency as of December 31, 2025). Looking ahead, we remain confident that integration and innovation are fundamental pillars for continuing to deliver high-quality services, accelerating technological deployment, and supporting the digital evolution of our customers and communities. In pursuit of this objective, we continue to evolve our business model to place people at the center and to provide technology, solutions, and opportunities that enhance their world. We unified our brand identity under Personal as the single integrating brand across our entire digital ecosystem, encompassing connectivity, entertainment, digital financial services, smart homes and offices, and enterprise and government solutions—enabling individuals, communities, and organizations to progress, engage, and transform. This forward-looking perspective is grounded in the relationship of trust we build every day with those who choose our services. Consolidated revenues in 2025 amounted to P$8,328,814 million as compared to P$5,442,958 million in 2024 and P$5,898,611 million in 2023. The increase of P$2,885,856 million in 2025 (a 53% increase) was mainly due to the consolidation of TMA’s results as of December 31, 2025, which contributed P$2,748,493 million of total revenues. The decrease of P$455,653 million in 2024 (a 7.7% decrease) was mainly due to the fact that the inflation rate for the last twelve months amounted to 117.8% and the Company (and other competitors in the ICT industry) did not transfer the totality of this inflation to its prices. Net loss in 2025 amounted to P$145,304 million as compared to a net income of P$1,359,230 million and a net loss of P$715,266 million in 2024 and 2023, respectively. Net loss for 2025 increased by P$1,504,534 million as compared to 2024. For a detailed analysis of our results of operations for fiscal year 2025, see “—Years ended December 31, 2025, 2024 and 2023” below. For a discussion of the factors that may affect our results of operations see “Item 3—Key Information—Risk Factors” and “—Years ended December 31, 2025, 2024 and 2023—Factors Affecting Results of Operations” and “—Trend Information” below. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 84 Table of Contents Non-IFRS Accounting Standards Measures The following discussion and analysis summarizes relevant measures of results of operations presenting items by nature. The Company believes that the presentation of the measures “Adjusted EBITDA,” “Operating Working Capital,” “Net Current Financial Liability” and “Working Capital” provide investors and financial analysts with appropriate information that is relevant to understanding the Company’s past and present performance and liquidity as well as our projections of future performance and liquidity. Moreover, Adjusted EBITDA is one of the key performance measures used by Management for monitoring the Company’s profitability and financial position, at consolidated levels. For more information on the use of Adjusted EBITDA and reconciliation of net income/(loss) to Adjusted EBITDA, see “—(A) Consolidated Results of Operations—Adjusted EBITDA.” Also, for more information on the use of Operating Working Capital, Net Current Financial Liability and Working Capital and reconciliation of these measures, see “—Liquidity and Capital Resources—Liquidity—Working Capital.” Years ended December 31, 2025, 2024 and 2023 For purposes of these sections, the fiscal years ended December 31, 2025, 2024 and 2023 are referred to as “2025,” “2024” and “2023,” respectively. Our results of operations are determined in accordance with IFRS Accounting Standards as issued by the IASB. Telecom provides customers with a broad range of telecommunication services. To fulfill its purpose, Telecom conducts different activities distributed among the companies in the Group. For further information about our main products and services, see “Item 4—The Business—Main Products and Services.” Factors Affecting Results of Operations Described below are certain factors that may be helpful in understanding our operating results. These factors are based on the information currently available to our Management and may not represent all the factors that are relevant to an understanding of our current or future results of operations. See also “Item 3—Key Information—Risk Factors.” Additional information regarding trends expected to influence our results of operations is analyzed below under “Trend Information.” The Argentine Economy Although a significant portion of our financial liabilities are denominated in foreign currencies, a substantial majority of our assets, operations and customers are located in Argentina. Accordingly, our financial condition, results of operations and cash flows depend to a significant extent on economic and political conditions prevailing in Argentina. The Argentine government has exercised and continues to exercise significant influence over many aspects of the Argentine economy. Accordingly, Argentine governmental actions concerning the economy could significantly affect private sector entities in general and our operations in particular, as well as affect market conditions, prices and returns on Argentine securities, including our outstanding securities and our shares. Our operating results, financial condition and cash flows have been and will be affected by fluctuations in the Argentine economy. For more information on these macroeconomic and political conditions, see “Item 3—Key Information—Risk Factors—Risks Relating to Argentina.” During the first half of 2025, global economic conditions remained subject to uncertainty, with monetary policy normalization proceeding at different speeds across jurisdictions and continued volatility in international capital flows affecting emerging market economies, including Argentina. Economic activity in Argentina expanded throughout 2025. The GDP increased by 5.8% in the first quarter, 6.3% in the second quarter, and 3.3% in the third quarter of 2025, compared to the same quarters of previous years. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 85 Table of Contents In 2025, public spending declined significantly compared to 2024. According to the latest estimates from the Argentine Ministry of Economy, a primary surplus of approximately 1.4% of GDP was recorded as well as a financial surplus of approximately 0.2% of GDP. This fiscal surplus resulted from measures implemented by the administration to streamline public sector accounts and maintain fiscal balance. As of December 31, 2025, the Argentine Peso depreciated in official markets 41% relative to December 31, 2024, as the Central Bank operated a banded exchange rate system designed to allow gradual adjustments of the peso while limiting excessive volatility, while inflation reached approximately 31.5% year-on-year. In 2025, the trade balance recorded a surplus of US$11,286 million. Argentina’s exports totaled US$87,077 million, reflecting a 9.2% increase, while imports amounted to US$75,791 million, representing a 24.6% increase. Following Argentina’s foreign-currency debt restructuring in 2020 and the subsequent approval of an IMF-supported Extended Fund Facility (“EFF”) confirmed by the Argentine Senate in 2022 and periodically reviewed since then, the IMF and Argentine authorities continued to implement the 48-month EFF program throughout 2025. The IMF Executive Board completed the first review of the program in July 2025, enabling a disbursement of approximately US$2 billion. The review welcomed Argentina’s commitments to safeguard the fiscal anchor, enhance the monetary framework, rebuild reserves, and pursue reforms consistent with the program’s objectives with strong policy implementation supporting continued growth and disinflation. As of December 31, 2025, Argentina’s country risk stood at 571 points, improving 64 points from December 31, 2024. Effect of Inflation Pursuant to IAS 29, the financial statements of entities whose functional currency is that of a hyperinflationary economy must be restated. IAS 29 does not prescribe when hyperinflation arises but includes several factors of hyperinflation. Since July 1, 2018, Argentina has been categorized as a hyperinflationary country, since certain macroeconomic indicators and events during 2018 evidenced that the qualitative and quantitative factors identified in IAS 29 (the quantitative factor being when the country’s projected three-year cumulative inflation rate exceeds 100%) were satisfied. Therefore, we have restated our Consolidated Financial Statements and the financial information in current Argentine Pesos as of December 31, 2025, for all the periods reported in this Annual Report based on certain price indexes to consider the effect of inflation in Argentina. See “Item 3—Key Information—Risk Factors—Risks Relating to Argentina—Inflation is high and could accelerate further, causing adverse effects on the economy and negatively impacting Telecom’s margins and/or ratios,” and Note 1.d) to our Consolidated Financial Statements. The CPI index has registered an increase of 31.5%, 117.8% and 211.4% on a year-over-year comparison for 2025, 2024 and 2023, respectively. See Note 1.d) to our Consolidated Financial Statements. The financial information issued for comparative purposes must also be presented in the current currency as of December 31, 2025, and must be restated using the annual index of the current year. As a result of applying the comprehensive inflation restatement, the Company will record an increase in the value of non-monetary items, such as Fixed and Intangible Assets, with an impact on deferred taxes and an increase in the Company’s equity, including shareholders’ contributions. Income Tax Inflation Adjustment In accordance with the provisions of the regulations in force in the Income Tax Law, the Company applies the income tax inflation adjustment set out in Title VI of the income tax law since fiscal year 2019, as that is the year the variation of the required CPI was verified. On December 1, 2022, Law No. 27,701 was enacted, which provided that taxpayers who determine a positive inflation adjustment in the first and second fiscal years beginning on January 1, 2022, may allocate one-third in that fiscal period and the remaining two-thirds in equal parts to the two immediately following fiscal periods. Said computation will proceed for those subjects who make investments in the purchase, construction, manufacture, elaboration or import of Fixed and Intangible Assets (except automobiles) during each of the two immediate fiscal periods following the computation of the first third, for an amount greater than or equal to P$30 billion. As the Company invested over P$30 billion per year in 2023, 2024 and 2025, it has determined the tax inflation adjustment as of December 31, 2022 and 2023 by imputation, as provided for in Law No. 27,701. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 86 Table of Contents Additionally, the update of the cost of several assets in case of disposal and the update of computable depreciation of Fixed and Intangible Assets, to all acquisitions or investments made in fiscal years beginning on January 1, 2018, based on changes in the CPI was generally established. On March 6, 2026, Law No. 27,802 (“Labor Modernization Law”) was published in the Official Gazette, introducing certain tax amendments. With respect to the Income Tax and inflation adjustment, the law provides that tax losses generated in fiscal years beginning on or after January 1, 2025, shall be adjusted based on the variation of the CPI recorded between the month-end of the fiscal year in which the losses were incurred and the month-end of the fiscal year being assessed. Accordingly, and pursuant to a comprehensive interpretation of applicable regulations, the Company recognized the corresponding accounting impact, that amounted to a loss of P$449,199 million as of December 31, 2025. Effects of Fluctuations in Exchange Rates between the Argentine Peso and the U.S. dollar and other major foreign currencies According to exchange rate information published by the Banco de la Nación Argentina, the Argentine Peso depreciated by 41.0% against the U.S. dollar during the year ended December 31, 2025 (compared to 27.7% and 356.3% in the years ended December 31, 2024, and 2023, respectively). The Milei administration has stated its intention to implement policies aimed at modifying Argentina’s macroeconomic conditions. In this regard, the BCRA announced the transition to a new macroeconomic stability framework, establishing a 2% monthly sliding path of the official exchange rate (this rate was adjusted to 1% during 2025). Additionally, the Relevamiento de Expectativas de Mercado (“REM”), published by the BCRA on January 9, 2025, estimated an annual inflation of 25.9 % for the year 2025. However, the effective inflation rate for 2025 was 31.5%. According to the REM, inflation for 2026 is projected to be approximately 22.4%. See “Item 10—Additional Information—Foreign Investment and Exchange Controls in Argentina.” and “Item 3—Key Information—Risk Factors—Risks Relating to Argentina—Devaluation of the Argentine Peso and foreign exchange restrictions may adversely affect our results of operations, our capital expenditures and our ability to service our liabilities and pay dividends.” The majority of our revenues are in Pesos whereas a portion of the costs regarding materials and supplies related to the construction and maintenance of our networks and services are incurred in foreign currencies. Also, the high level of competition limited our ability to transfer to our customers the fluctuations in the exchange rates between the Peso and the U.S. dollar and other major foreign currencies. In addition, any devaluation of the Peso against foreign currencies may increase operating costs (partially offset by the increase of revenues in foreign currencies), capital expenditures and the cost of debt, which will adversely affect our results of operations, considering the net effect on revenues and costs. Additionally, any significant devaluation of the Peso will result in an increase in the cost of servicing our debt and, therefore, may have a material adverse effect on our results of operations. See “Item 3—Key Information—Risk Factors—Risks Relating to Argentina—Devaluation of the Argentine Peso and foreign exchange restrictions may adversely affect our results of operations, our capital expenditures and our ability to service our liabilities and pay dividends.” The following tables show, for the periods indicated, certain information regarding the exchange rates for U.S. dollars, expressed in nominal Pesos per dollar (ask price published by Banco de la Nación Argentina).

ARPU is not a measure calculated in accordance with IFRS Accounting Standards and our measure of ARPU may not be calculated in the same manner as similarly titled measures used by other companies. Certain components of service revenues are excluded from ARPU calculations presented in this Annual Report. Management believes this measure is helpful in assessing the development of the customer base of our services.

However, ENACOM is entitled to observe the prices we set if it understands that they do not comply with the provisions of Section 48 of the LAD. If prices were observed and we are forced to reduce them, our operating margins may be negatively affected. Competition The fixed and mobile telephony, cable television and internet businesses are competitive. We are required to make significant investments to refurbish and maintain our existing network infrastructure to comply with regulatory obligations and remain competitive with respect to the quality of our services. For more information, see “Item 4- The Business- Main Products and Services.” PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 88 Table of Contents Technology Developments and Capital Expenditures Improvements in technology influence our customers’ demand for services and equipment. For example, demand for fixed-line telecommunications services has been affected by continued significant growth in the mobile business. Growth in the telephony as well as cable television services businesses at present is being affected by the expansion of Broadband for individuals and corporations and our continuous updating of commercial and support systems. The increase in Broadband adoption has also proven to be a critical factor in facilitating the offering of Value Added Services to customers and the combination of products made available to customers. In internet services, we must constantly upgrade our access to technology and software, embrace emerging transmission technologies and improve the responsiveness, functionality, coverage and features of our services. In the mobile business, to provide customers with new and better services, Telecom must enhance its mobile networks extending 4G/4G+ technology and bandwidth for mobile data transmission. Moreover, Telecom is developing an LTE infrastructure expeditiously, in response to regulatory requirements and development in the market for mobile services. For more information regarding our LTE infrastructure developments, please see “Item 4—The Business—Mobile Telecommunications Services—Network and Equipment” and “Item 5—Liquidity and Capital Resources—Capital Expenditures.” We are continuing with the deployment and expansion of 5G technology that will allow us to expand our product portfolio and meet market demands in the future. In addition, as new technologies develop, equipment may need to be replaced or upgraded, and network facilities (in particular, mobile and internet network facilities) may need to be rebuilt in whole or in part, at substantial cost, to remain competitive. These enhancements and the implementation of new technologies will continue requiring increased capital expenditures. See “Item 4—Information on the Company—Capital Expenditures” and “Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Capital Expenditures.” Tax pressures and litigation Local municipalities in the regions where we operate have introduced regulations and proposed various taxes and fees for the installation of infrastructure, equipment and expansion of fixed-line and mobile networks. Local and federal tax authorities have brought an increasing number of claims against us. We disagree with these proceedings and are generally contesting them. Also, jurisprudential changes in labor and pension matters have generated higher claims from employees and former employees and increased claims from employees of a contractor or subcontractor alleging joint liability. We cannot assure you that current laws and regulations applicable to the economy generally or specifically to the telecommunications industry will not become more burdensome, that the claims will be resolved in our favor, or that any changes to the existing laws and regulations will not adversely affect our business, financial condition, results of operations and cash flows as well. (A) Consolidated Results of Operations As disclosed “Item 4—Information on the Company— Recent Developments—Acquisition of TMA,” on February 24, 2025, the Company acquired 99.999625% of TMA’s capital stock. Since that date, the Company has consolidated TMA, and, as a result, the Company’s results of operations for 2025 include TMA’s results as of the Acquisition date and are not directly comparable to the Company’s results of operations for 2024. For 2025, we reported a net loss of P$145,304 million, compared to a net income of P$1,359,230 million in 2024 and a net loss of P$715,266 million in 2023. Net loss for 2025 increased by P$1,504,534 million compared to 2024, while the net income for 2024 increased by P$2,074,496 million compared to 2023. Consolidated revenues in 2025 amounted to P$8,328,814 million as compared to P$5,442,958 million in 2024 and P$5,898,611 million in 2023. The increase of P$2,885,856 million in 2025 (a 53% increase) was mainly due to the consolidation of TMA’s results as of December 31, 2025, which contributed P$2,748,493 million of total revenues. The decrease of P$455,653 million in 2024 (a 7.7% decrease) was mainly due to the fact that the inflation rate for the last twelve months amounted to 117.8% and the Company (and other competitors in the ICT industry) did not transfer the totality of this inflation to its prices. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 89 Table of Contents In 2025, operating costs (including depreciation, amortization and impairment of Fixed and Intangible Assets) amounted to P$7,878,767 million, representing an increase of P$2,243,133 million, or 39.8% as compared to 2024. The increase in operating costs in 2025 was mainly due to the consolidation of TMA’s results as of December 31, 2025, which contributed P$2,683,747 million. In 2024, operating costs (including depreciation, amortization and impairment of Fixed and Intangible Assets) amounted to P$5,635,634 million, representing a decrease of P$621,246 million, or 9.9% as compared to 2023. The decrease in operating costs in 2024 was mainly due to lower Depreciation, amortization and impairment of Fixed and Intangible Assets costs. The Executive Committee and the CEO have a strategic and operational vision of Telecom as a single business unit. This reflects the current regulatory context of the converged ICT Services industry, under which mobile services, internet services, cable television and fixed and data services, are all governed by the same regulatory framework and therefore consolidated into a single segment. To exercise their functions, both the Executive Committee and the CEO periodically receive the economic-financial information of Telecom Argentina and its subsidiaries located in Argentina except TMA (stated in historic currency at the transaction date) prepared as a single segment and evaluate the evolution of the business as a single results-generating unit, administrating the resources in a unique way to achieve the objectives. Costs are not specifically allocated to a type of service, as Telecom Argentina has a single payroll and operating expenses that affect all services in general. Further, decisions on capital expenditures affect all types of services provided by Telecom Argentina and its subsidiaries in Argentina except TMA and are not allocated specifically to one of them. Following the acquisition of TMA, dated February 24, 2025, the Company identified a new reportable segment, “ICT Services provided in Argentina – TMA Network” corresponding to the provision of mobile and fixed telephony services, fixed broadband, and video services on a nationwide scale in Argentina, using TMA’s own networks, with its own infrastructure. TMA is managed as a separate business unit, and therefore, the Executive Committee and the CEO review its economic and financial information (stated in historic currency at the transaction date) separately. Costs are not specifically allocated to a type of service, as TMA has a single payroll and operating expenses that affect all services in general. Further, decisions on capital expenditures affect all the types of services provided by TMA and are not allocated specifically to one of them. Additionally, Telecom, through Micro Sistemas, develops activities in the fintech industry in Argentina. Telecom also carries out activities abroad (Paraguay, USA, Uruguay and Chile). The operations that Telecom develops through Micro Sistemas, and those developed abroad, are not analyzed as a separate segment by the Executive Committee and the CEO, considering that they are not considered as individually significant. These operations do not meet the aggregation criteria established by the standard to be grouped within the “ICT Services provided in Argentina– Personal Network” segment and considering that they do not exceed any of the quantitative thresholds identified in the standard to qualify as reportable segments, they are grouped within the category “Other segments.” As a result, segments as of December 31, 2025, are the following: ● ICT Services provided in Argentina – Personal Network. ● ICT Services provided in Argentina – TMA Network ● Other segments. The Executive Committee and the CEO evaluate the profitability for each reportable segment based on the measure of the Adjusted EBITDA. Adjusted EBITDA is defined as our net (loss) income less income tax, financial results, earnings (losses) from associates and joint ventures, and depreciation, amortization and impairment of Fixed and Intangible Assets, reviewing this information in the currency of the date of each transaction.

In 2025, net loss amounted to P$145,304 million compared to a net income of P$1,359,230 million in 2024, representing (1.7)% and 25% of consolidated revenues in 2025 and 2024, respectively. The increase in net loss in 2025 compared to 2024 was mainly due to the P$2,743,278 million increase in net financial loss, partially offset by higher operating results of P$642,723 million, a lower income tax loss of P$584,669 million and lower losses from associates and joint ventures of P$11,352 million. Net loss attributable to controlling shareholders amounted to P$170,006 million in 2025 compared to net income of P$1,331,805 million in 2024. Net loss contains an income of P$61,044 million corresponding to the consolidation of TMA’s results. During 2025 revenues increased 53%, or P$2,885,856 million, compared to 2024, amounting to P$8,328,814 million. The increase in revenues was mainly due to the consolidation of TMA’s results, which contributed P$2,748,493 million of total revenues. As a result of the restatement in current currency as of December 31, 2025, revenues included a restatement effect of P$895,695 million and P$2,029,239 million in 2025 and 2024, respectively. For further information about revenue see “Explanations by segments” below. Total operating costs without depreciation, amortization and impairment of Fixed and Intangible Assets totaled P$5,803,279 million in 2025, representing an increase of P$1,892,702 million or 48.4% compared to 2024. Operating costs include P$2,104,182 million corresponding to the consolidation of TMA’s results. As a result of the restatement in current currency as of December 31, 2025, the restatement effect included in operating costs without depreciation, amortization and impairment of Fixed and intangible Assets amounted to P$727,963 million and P$1,511,055 million in 2025 and 2024, respectively. For further information regarding operating costs without depreciation, amortization and impairment of Fixed and Intangible Assets see “Explanations by segments” below. Depreciation, amortization and impairment of Fixed and Intangible Assets Depreciation, amortization and impairment of Fixed and Intangible Assets amounted to P$2,075,488 million in 2025, representing an increase of P$350,431 million or 20.3% compared to 2024. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 91 Table of Contents This increase was primarily driven by P$579,565 million corresponding to the consolidation of TMA’s results. Excluding the impact of the consolidation of TMA, depreciation, amortization and impairment of Fixed and Intangible Assets decreased primarly due to the effect of those assets that ended their useful life after December 31, 2024, partially offset by the depreciation and amortization of registrations after that date, which, in turn, decreased compared to 2024. As a result of the restatement in current currency as of December 31, 2025, the restatement effect included in depreciation, amortization and impairment of Fixed and Intangible Assets amounted to P$1,411,462 million and P$1,499,317 million in 2025 and 2024, respectively. Operating income (loss) Operating income in 2025 amounted to P$450,047 million compared to an operating loss of P$192,676 million in 2024. Operating income / (loss) represented 5.4 % and (3.5) % of revenues in 2025 and 2024, respectively. Operating income for 2025 includes P$64,746 million corresponding to the consolidation of TMA’s results.

Financial results, net contain an income of P$35,461 million, corresponding to the consolidation of TMA’s results. The variation in financial results, net for 2025 was mainly driven by a higher loss from foreign exchange differences, measured in real terms, of P$2,794,475 million, reflecting the aggregate effect of foreign currency exchange losses on borrowings and other foreign currency exchange losses. This loss was driven by an inflation rate of 31.5% versus an appreciation of the U.S. dollar against the Argentine peso of 41%, compared to an inflation rate of 117,8% and a U.S. dollar appreciation of 27.7% in 2024. Additionally, interest on borrowings increased by P$212,289 million and other net adverse movements for P$24,320 million. These factors were partially offset by a higher gain from changes in the fair value of financial assets of P$148,192 million, resulting from the 31.5% inflation impact on the quoted value of such instruments (compared to 117.8% inflation in 2024), and a higher gain from remeasurement in borrowings of P$139,614 million, as the UVA index adjustment lagged inflation, resulting in positive results. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 92 Table of Contents Income tax benefit (loss) Telecom’s income tax includes the following effects: (i) the current tax payable pursuant to tax legislation applicable to Telecom, and (ii) the effect of applying the deferred tax method on temporary differences arising out of the Company’s asset and liability valuation according to tax versus financial accounting criteria, including the income tax inflation effect. Income tax benefit amounted to P$46,432 million in 2025 compared to an expense of P$538,237 million in 2024. It includes the following effects: (i) current tax expenses, Telecom generated a P$196,068 million tax expense in 2025 (compared to an expense of P$14,344 million in 2024), (ii) regarding the deferred tax in 2025, Telecom recorded a deferred tax benefit of P$242,500 million compared to an expense of P$523,893 million in 2024. Income tax benefit (loss) includes P$39,163 million corresponding to the consolidation of TMA’s results. For more information on income tax, see Notes 3 and 16 to our Consolidated Financial Statements. Adjusted EBITDA An important operational performance measure used by the Company’s Chief Operating Decision Maker (as this term is defined in IFRS Accounting Standards 8) is Adjusted EBITDA. Adjusted EBITDA is defined as our net income (loss), less income tax, financial results, earnings (losses) from associates and joint ventures, and depreciation, amortization and impairment of Fixed and Intangible Assets. We believe Adjusted EBITDA facilitates company-to-company operating performance comparisons by backing out potential differences caused by variations such as capital structures, taxation and the useful lives and book depreciation and amortization of PP&E and intangible assets, which may vary for different companies for reasons unrelated to operating performance. Although Adjusted EBITDA is not a measure defined in accordance with IFRS Accounting Standards (a non-GAAP measure), our Management believes that this measure facilitates operating performance comparisons from period to period and provides useful information to investors, financial analysts and the public in their evaluation of our operating performance. Adjusted EBITDA does not have a standardized meaning and, accordingly, our definition of Adjusted EBITDA may not be comparable to Adjusted EBITDA as used by other companies. The following table shows the reconciliation of Net income (loss) to Adjusted EBITDA: Year ended December 31, 2025 2024 Total Change (P$ million) % (P$ million) Net income (loss) (145,304) 1,359,230 n/a (1,504,534) Income tax (benefit) expense (46,432) 538,237 n/a (584,669) Other financial results, net (110,799) (190,451) (41.8) 79,652 Financial results from borrowings 748,840 (1,914,786) n/a 2,663,626 Losses from associates and joint ventures 3,742 15,094 (75.2) (11,352) Operating income (loss) 450,047 (192,676) n/a 642,723 Depreciation, amortization and impairment of Fixed and Intangible Assets 2,075,488 1,725,057 20.3 350,431 Adjusted EBITDA 2,525,535 1,532,381 64.8 993,154 Our consolidated Adjusted EBITDA amounted to P$2,525,535 million in 2025, representing an increase of P$993,154 million or 64.8% as compared to P$1,532,381 million in 2024.

Mobile internet services revenues represented 98% of the mobile services revenues for the year ended December 31, 2025, and 2024. The effect generated by the restatement in current currency as of December 31, 2025, included in Mobile services revenues amounted to P$254,754 million and P$749,297 million in 2025 and 2024, respectively. This increase was mainly due to a 15.8% increase in ARPU, partially offset by a 7.8% decrease in the number of customers. Personal’s ARPU amounted to P$9,081.9 for the year ended December 31, 2025, compared to P$7,840.3 for the year ended December 31, 2024. This increase was mainly explained by price increases. The effect generated by the restatement in current currency as of December 31, 2025, included in ARPU amounted to P$1,016.1 and P$2,906.3 as of December 31, 2025 and 2024, respectively. Personal’s mobile customers amounted to 19.9 million and 21.6 million as of December 31, 2025, and 2024, respectively. The decrease is mainly due to: (a) a change implemented in 2025 for the prepaid customer base in the measurement of line useful life, which was reduced from 360 days to 242 days to consider the definitive disconnection since the last top-up date, resulting in a 10.7% reduction in the prepaid customer base; and (b) higher disconnections in postpaid customers, associated with changes in commercial strategies, with the postpaid customer base declining by 3.2%. As of December 31, 2025, 60% of total mobile customers were prepaid customers and 40% were postpaid customers, compared to 62% and 38%, respectively, as of December 31, 2024. Additionally, the average monthly churn rate amounted to 2.1% in 2025, compared to 1.4% in 2024.

The effect generated by the restatement in current currency as of December 31, 2025, included in internet services revenues amounted to P$152,971 million and P$487,820 million in 2025 and 2024, respectively. The increase in internet services revenues in 2025 was mainly due to the increase in the Broadband Internet access ARPU of 0.8% and a 3.2% increase in the customer base. ARPU reached P$27,062.6 in 2025 as compared to P$26,860.4 in 2024. This increase in ARPU is mainly explained by price increases, partially offset by an increase in discounts granted to customers compared to 2024. The effect generated by the restatement in current currency as of December 31, 2025, included in ARPU amounted to P$2,929.7 and P$9,934.2 as of December 31, 2025 and 2024, respectively.

The effect generated by the restatement in current currency as of December 31, 2025, included in cable television services revenues amounted to P$83,100 million and P$256,087 million in 2025 and 2024, respectively. The increase in cable television service revenues in 2025 was mainly due to a 2.8% increase in ARPU and a 1.4% increase in the customer base. The ARPU amounted to P$18,643.2 in 2025, compared to an ARPU of P$18,143.6 in 2024. The increase in ARPU reflects the impact of price increases implemented throughout the year. The effect generated by the restatement in current currency as of December 31, 2025 included in ARPU amounts to P$1,704.9 and P$6,456.3 as of December 31, 2025 and 2024, respectively As of December 31, 2025, the customer base in Argentina amounted to 3.3 million customers, representing a 1.4% increase compared to 2024, driven by Flow Full and Flow Plus products. Flow Plus, which combines live TV, on-demand content, and streaming platforms in a flexible manner, was launched in June 2025 and began to be marketed as main product from the fourth quarter of 2025. Additionally, the average monthly churn rate amounted to 1.5% and 1.8% in 2025 and 2024, respectively.

The effect generated by the restatement in current currency as of December 31, 2025, included in fixed and data services revenues amounted to P$63,923 million and P$248,500 million in 2025 and 2024, respectively. The decrease was primarily attributable to the Company’s inability to adjust prices at a pace consistent with inflation, considering accumulated inflation of 31.5% over the last twelve months, while the customer base remained stable. The customer base of fixed telephony services amounted to 2.7 million (of which 2.3 million are IP fixed telephony service base) in 2025, compared to 2.7 million in 2024 (of which 1.9 million are IP fixed telephony service base). Other services revenues Other services revenues generated by other services amounted to P$109,584 million in 2025 (equivalent to 2% and 1% of total services revenues for ICT Services provided in Argentina – Personal Network in 2025 and 2024, respectively), increasing P$71,232 million as compared to P$38,352 million in 2024. The effect generated by the restatement in current currency as of December 31, 2025, included in other services revenues amounted to $10,675 million and $14,083 million in 2025 and 2024, respectively. The increase in 2025 compared to 2024 is mainly due to interconnection services provided to the ICT Services segment in Argentina – TMA Network provided during 2025. These revenues are eliminated at the consolidated level as part of the consolidation process, as they constitute a transaction between subsidiaries. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 98 Table of Contents Equipment Equipment revenues amounted to P$251,186 million in 2025 (representing 4.8% of total revenues for ICT Services provided in Argentina – Personal Network), decreasing P$71,954 million, or 22.3%, as compared to P$323,140 million in 2024. The effect generated by the restatement in current currency as of December 31, 2025, included in equipment revenues amounted to P$30,192 million and P$116,713 million in 2025 and 2024, respectively. The decrease was mainly due to the fact that the Company was unable to increase its prices to the same extent as the increase in inflation, partially offset by an increase in the number of handsets sold compared to 2024. Operating costs (without depreciation, amortization and impairment of Fixed and Intangible Assets) for ICT Services provided in Argentina – Personal Network are comprised as follows: Operating costs (without depreciation, amortization and impairment of Fixed and Intangible Assets) for ICT Services provided in Argentina – Personal Network totaled P$3,523,481 million in 2025, representing a decrease of P$79,780 million or 2.2% compared to P$3,603,261 million in 2024. The effect generated by the restatement in current currency as of December 31, 2025, included in Operating costs (without depreciation, amortization and impairment of Fixed and Intangible Assets) amounted to P$453,616 million and P$1,391,905 million in 2025 and 2024, respectively. Employee benefit expenses and severance payments Employee benefit expenses and severance payments decreased P$69,611 million to P$1,237,441 million in 2025 as compared to P$1,307,052 million in 2024. The effect generated by the restatement in current currency as of December 31, 2025, included in Employee benefit expenses and severance payments amounted to P$140,974 million and P$483,077 million in 2025 and 2024, respectively. The decrease was mainly due to lower severance payments and a reduction in headcount of 6.7%, amounting to 18,085 employees as of December 31, 2025, and, partially offset by compensation increases for employees covered by collective bargaining agreements (as agreed by the Company with the various labor unions) as well as for employees not covered by such agreements. Fees for services, maintenance, materials and supplies Fees for services, maintenance, materials and supplies decreased P$16,764 million or 2.5%, amounting to P$655,777 million in 2025 as compared to P$672,541 million in 2024. The effect generated by the restatement in current currency as of December 31, 2025, included in Fees for services, maintenance, materials and supplies amounted to P$93,997 million and P$279,499 million in 2025 and 2024, respectively. The variation is mainly explained by the efficiency and management of resources through which fees for services decreased by P$15,492 million and maintenance and materials costs by P$3,164 million compared to 2024. Taxes and fees with the Regulatory Authority Taxes and fees with the Regulatory Authority, including turnover tax, municipal taxes and other taxes, increased P$32,985 million or 8.0%, amounting to P$443,828 million in 2025 as compared to P$410,843 million in 2024. Taxes and fees with the Regulatory Authority represent 8.4% and 8.2% of total revenues in 2025 and 2024, respectively. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 99 Table of Contents The effect generated by the restatement in current currency as of December 31, 2025, included in Taxes and fees with the Regulatory Authority amounted to P$49,872 million and P$152,324 million in 2025 and 2024, respectively. The increase is mainly driven by the effect of tax charges arising from the higher revenue’s levels described above. Commissions and advertising Commissions and advertising increased P$18,742 million or 9.0%, amounting to P$227,669 million in 2025, as compared to P$208,927 million in 2024. The effect generated by the restatement in current currency as of December 31, 2025, included in Commissions and advertising amounted to P$24,785 million and P$74,995 million in 2025 and 2024, respectively. The increase is mainly due to higher advertising costs related to Flow campaigns (such as Flow Music, Flow Content, Flow Sports, among others). In addition, there was an increase in expenditure aimed at strengthening the positioning and visibility of the Personal brand. Programming and content costs Programming and content costs increased by P$29,594 million or 10.9%, amounting to P$301,703 million in 2025 as compared to P$272,109 million in 2024. The effect generated by the restatement in current currency as of December 31, 2025, included in Programming and content costs amounted to P$33,898 million and P$99,687 million in 2025 and 2024, respectively. The increase corresponds to the rise in Premium channel services, mainly in the Football Pack. Other operating costs without depreciation, amortization and impairment of Fixed and Intangible Assets Other operating expenses (which include legal claims and contingent liabilities, energy and other public services, insurance, rentals and internet capacity, interconnection and transmission costs, cost of equipment, among others) decreased P$74,726 million or 10.2%, amounting to P$657,063 million in 2025 as compared to P$731,789 million in 2024. The effect generated by the restatement in current currency as of December 31, 2025, included in Other operating expenses amounts to P$110,090 million and P$302,323 million in 2025 and 2024, respectively. The decrease is mainly explained by: i) lower costs of equipment sold ‒although the number of mobile devices sold increased compared to 2024, their costs did not increase in line with the accumulated inflation of 31.5% over the past twelve months; ii) lower interconnection costs were recorded, resulting from changes in contracting criteria associated with the new business dynamics, which allowed for optimization of link and site usage, together with lower traffic levels, partially offset by higher roaming costs; and iii) a reduction in bad debt expense, attributable to the continuation of the recovery actions implemented by the Company. These effects were partially offset by legal proceedings and other contingencies, as well as rental and internet capacity costs.

These revenues correspond to services provided in Paraguay. The effect generated by the restatement in current currency as of December 31, 2025, included in Mobile services revenues amounted to P$19,996 million and P$74,135 million in 2025 and 2024, respectively. The decrease in 2025 compared to 2024 was primarily attributable to a decrease in ARPU, mainly driven by lower top-up levels from prepaid customers. This effect is partially offset by the appreciation of the Guaraní against the Argentine peso in real terms (40.1% over the last twelve months), compared to an accumulated inflation rate of 31.5% in 2025. Paraguay’s ARPU amounted to P$5,886.9 for the year ended December 31, 2025 (compared to P$6,516.9 for the year ended December 31, 2024), representing a 9.7% decrease. Our customer base in Paraguay remained stable at 2.6 million as of December 31, 2025, and 2024. As of December 31, 2025, 70% of our customers were prepaid and 30% were postpaid, compared to 73% prepaid and 27% postpaid as of December 31, 2024. Average monthly churn reached 2.6% in 2025 compared to 2.7% in 2024. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 106 Table of Contents Internet Services Internet services revenues amounted to P$79,070 million in 2025 (equivalent to 18.6% of total services revenues from Other segments), representing an increase of P$5,981 million or 8.2%, compared to P$73,089 million in 2024. The effect generated by the restatement in current currency as of December 31, 2025, included in internet services revenues amounted to P$8,379 million and P$28,162 million in 2025 and 2024, respectively. These revenues include P$78,771 million from services provided in Paraguay and P$299 million from services provided in Uruguay. The increase in sales is attributable to the appreciation of the Guaraní against the Argentine peso in real terms (40.1% over the last twelve months), compared to an accumulated inflation rate for the fiscal year of 31.5% and the increase in the customer base of 10.1%, as a result of commercial efforts to capture new customers. The total customer base considering Paraguay and Uruguay amounted to 0.3 million as of December 31 2025 and 2024, respectively. Cable Television Services Cable television service revenues amounted to P$87,816 million in 2025 (equivalent to 20.7% of total services revenues from Other segments), representing a decrease of P$9,840 million or 10.1% compared to P$97,656 million in 2024. The effect generated by the restatement in current currency as of December 31, 2025, included in cable television services revenues amounted to P$9,798 million and P$38,059 million in 2025 and 2024, respectively.

The decrease in cable television service revenues in Uruguay is attributable to a 10.4% reduction in the customer base, mainly due to customer migration to streaming and OTT platforms and increased competitive pressure. This decrease was partially offset by price increases implemented during the year and by the appreciation of the Uruguayan peso against the Argentine peso (57.5% over the last twelve months), compared to an accumulated inflation rate for the fiscal year of 31.5%. The decrease in cable television service revenues in Paraguay is attributable to a 1.9% reduction in the customer base, partially offset by price increases and by the appreciation of the Guaraní against the Argentine peso (40.1% over the last twelve months), compared to an accumulated inflation rate for the fiscal year of 31.5%. Fixed and Data Services Revenues generated by fixed and data services amounted to P$12,347 million in 2025 (equivalent to 2.9% of total services revenues from Other segments), representing an increase of P$1,753 million or 16.5% as compared to P$10,594 million in 2024. The effect generated by the restatement in current currency as of December 31, 2025, included in fixed and data services revenues amounted to P$1,347 million and P$3,993 million in 2025 and 2024, respectively.

Other services revenues Other services revenues generated by other services amounted to P$58,309 million in 2025 (equivalent to 13.7% of total services revenues from Other segments), representing an increase of P$5,369 million or 10.1% as compared to P$52,940 million in 2024. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 107 Table of Contents The effect generated by the restatement in current currency as of December 31, 2025, included in other services revenues amounted to $6,455 million and $19,288 million in 2025 and 2024, respectively. These services mainly include revenues related to fintech services, administrative fees, and advertising space sales, among others. The variation was primarily driven by the increase in fintech services in Argentina, mainly due to the growth in the adoption of the “Personal Pay” digital wallet and the expansion in the number of users, which reached 4.7 million in 2025 compared to 3.6 million in 2024, representing a 28.8% increase. On January 22, 2026, Telecom Argentina, together with its subsidiaries Micro Fintech Holding and Micro Sistemas, entered into a framework agreement with Banco Macro, pursuant to which Banco Macro made a capital contribution and, as a result, subscribed for shares representing 50% of the share capital and voting rights of Micro Sistemas. For additional information, see “Item 4—Information on the Company—Recent Developments—Agreement between Telecom Argentina, Micro Fintech Holding and Micro Sistemas with Banco Macro S.A.” Equipment Equipment revenues amounted to P$7,122 million in 2025, representing a decrease of P$3,264 million or 31.4% as compared to P$10,386 million in 2024.

The effect generated by the restatement in current currency as of December 31, 2025, included in Employee benefit expenses and severance payments amounted to P$4,148 million and P$15,235 million in 2025 and 2024, respectively. Fees for services, maintenance, materials and supplies Fees for services, maintenance, materials and supplies decreased P$635 million or 1.1%, amounting to P$57,824 million in 2025 as compared to P$58,459 million in 2024. The variation is mainly explained by efficiency measures and resources management, under which maintenance and materials costs decreased by P$4,548 million, partially offset by an increase in service fees of P$3,933 million compared to 2024. These costs mainly relate to Paraguay and the Fintech business. The effect generated by the restatement in current currency as of December 31, 2025, included in Fees for services, maintenance, materials and supplies amounted to P$6,184 million and P$22,620 million in 2025 and 2024, respectively.

These transactions are eliminated at the consolidated level but reported within each individual segment. They mainly relate to interconnection services provided between Telecom Argentina and TMA, and to foreign subsidiaries. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 109 Table of Contents (A.2) 2024 Compared to 2023 As of December 31, 2024, Telecom carried out its activities in Argentina and abroad (Paraguay, Uruguay, the United States and Chile). These operations were not analyzed as a separate segment by the Executive Committee and the CEO, who analyzed the consolidated information from Telecom Argentina and its ICT services subsidiaries (in currency of the transaction’s dates) treating all operations as a single segment. Additionally, Telecom, through Micro Sistemas, developed activities in the fintech industry in Argentina. The operations that Telecom developed through Micro Sistemas, and those developed abroad, were not analyzed as a separate segment by the Executive Committee and the CEO, considering that they are not considered as individually significant. These operations do not meet the aggregation criteria established by the standard to be grouped within the “ICT Services in Argentina” segment and considering that they do not exceed any of the quantitative thresholds identified in the standard to qualify as reportable segments, they are grouped within the category “Other segments.” Since operations of Fintech Services and abroad were not material, the explanations set forth below reflect mainly developments and information attributable to our ICT services in Argentina.

For further information on the use of Adjusted EBITDA, see “—Adjusted EBITDA” below. In 2024, net income amounted to P$1,359,230 million, representing 25% of consolidated revenues. The increase in net income in 2024 compared to 2023 was mainly due to an increase in positive financial results of P$3,425,816 million, partially offset by an increase in income tax loss of P$1,507,227 million. In 2024, Adjusted EBITDA totaled P$1,532,381 million, representing 28.2% of consolidated revenues. The decrease in 2024 compared to 2023 was mainly due to a decrease in consolidated revenues of P$455,653 million, partially offset by the decrease in operating costs (without depreciation, amortization and impairment of Fixed and Intangible Assets) of P$328,265 million.

Despite increased demand for services, consolidated revenues decreased mainly due to the 117.8% inflation rate over the past twelve months, as the Company and other competitors in the ICT industry did not transfer the totality of this inflation to its prices. Services revenues amounted to P$5,109,432 million in 2024, decreasing 6.4% as compared to P$5,459,835 million in 2023 and represented 93.9% of consolidated revenues. Equipment revenues amounted to P$333,526 million in 2024 as compared to P$438,776 million in 2023 and represented 6.1% of consolidated revenues. The effect generated by the restatement in current currency as of December 31, 2025, increased consolidated revenues by P$2,029,239 million and P$4,768,781 million in 2024 and 2023, respectively. Consolidated revenues for 2024 and 2023 are comprised as follows: Mobile Services Mobile services revenues in 2024 amounted to P$2,209,144 million (a decrease of P$167,235 million or 7.0% as compared to 2023), being the principal contributor to our total services revenues for 2024 (43.2% of consolidated services revenues in 2024 as compared to 43.5% in 2023). Mobile internet services revenues represented 95% of the mobile services revenues as of December 31, 2024 and 2023. The effect generated by the restatement in current currency as of December 31, 2025, included in Mobile services revenues amounted to P$823,432 million and P$1,921,758 million in 2024 and 2023, respectively. Mobile services revenues ICT Services provided in Argentina – Personal Network amounted to P$2,018,793 million (a decrease of P$167,061 million as compared to 2023). This decrease was mainly due to a 10.4% decrease in the ARPU, partially offset by a 3.0% increase in the number of customers. Personal’s ARPU amounted to P$7,840.3 for the year ended December 31, 2024 (compared to P$8,754.7 for the year ended December 31, 2023). This decrease was mainly explained by the fact that, as a consequence of the 117.8% inflation in Argentina, the Company (and other competitors in the ICT industry) was unable to increase its prices during 2024 to the same extent as the increase in inflation (the effect generated by the restatement in current currency as of December 31, 2025 included in ARPU amounted to P2,906.3 and P$7,081.0 as of December 31, 2024 and 2023, respectively). Additionally, the decrease in ARPU is also explained by the fact that we granted greater discounts to customers in order to maintain the customer base, considering the intense competition in the market and an increase in customers of prepaid services of 4.2% (which have a lower ARPU than postpaid customers). PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 111 Table of Contents Personal’s mobile customers amounted to 21.6 million and 21.0 million as of December 31, 2024, and 2023, respectively. Out of the total mobile customers as of December 31, 2024, 62% were prepaid customers and 38% were postpaid customers, whereas as of December 31, 2023, 61% were prepaid customers and 39% were postpaid customers. During 2024, we observed a change in customer behavior, resulting in an increase of 4.2% in prepaid services customers and 0.9% in the postpaid services customers. Additionally, the average churn rate per month amounted to 1.4% in 2024 (compared to a 1.8% average in 2023). ARPU of Mobile Services – ICT Services provided in Argentina – Personal Network A monthly operational measure used in the mobile services is ARPU, which we calculate by dividing adjusted total service revenues—excluding out collect wholesale roaming, cell site rental, reconnection fees revenues and others—(divided by 12 months) by the average number of customers during the year. ARPU is not a measure calculated in accordance with IFRS Accounting Standards and our measure of ARPU may not be calculated in the same manner as similarly titled measures used by other companies. Certain components of service revenues are excluded from Personal’s ARPU calculations presented in this Annual Report. Management believes this measure is helpful in assessing the development of the subscriber base of mobile services. The following table shows the reconciliation of total service revenues to such revenues included in the ARPU calculations of 2024 and 2023: Year ended December 31, Year ended December 31, 2024 2023 (P$ million) Total Mobile service revenues Network 2,018,793 2,185,854 Components of service revenues not included in the ARPU calculation: out collect wholesale roaming, cell sites rental, reconnection fees revenues and others (16,520) (18,071) Adjusted total service revenues included in the ARPU calculation 2,002,273 2,167,783 Average number of customers during the year (millions) 21.3 20.6 ARPU of Mobile Services - ICT Services provided in Argentina - Personal Network 7,840.3 8,754.7 Mobile services revenues generated in Paraguay amounted to P$190,351 million in 2024 (compared to P$190,525 million in 2023, representing a 0.1% decrease). This variation was mainly due to the decrease in Núcleo’s ARPU of 15.0%, partially offset by an increase of a 10.6% in the customer base. Núcleo’s ARPU amounted to P$6,516.9 for the year ended December 31, 2024 (compared to P$7,663.2 for the year ended December 31, 2023). The decrease in ARPU was mainly due to the fact that we granted greater discounts to customers in order to maintain the customer base, considering the intense competition. Núcleo’s customer amounted to 2.6 million and 2.3 million as of December 31, 2024, and 2023, respectively. Out of the total mobile customers as of December 31, 2023, 73% were prepaid customers and 27% were postpaid customers, whereas as of December 31, 2023, 76% were prepaid customers, and 24% were postpaid customers. Additionally, the average churn rate per month amounted to 2.7% and 2.9% in 2024 and 2023, respectively. Internet Services Internet services revenues amounted to P$1,390,491 million in 2024 (equivalent to 27.2% of total consolidated services revenues), increasing P$101,672 million or 7.9% as compared to P$1,288,819 million in 2023. The effect generated by the restatement in current currency as of December 31, 2025, included in internet services revenues amounted to P$515,982 million and P$1,039,317 million in 2024 and 2023, respectively. The increase in internet services revenues in 2024 was mainly due to the increase in the Broadband Internet access ARPU of 8.1%. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 112 Table of Contents The ARPU reached P$26,860.4 in 2024 as compared to P$24,841.1 in 2023. This increase in ARPU is mainly explained by the fact we granted less discounts to customers in these services. The effect generated by the restatement in current currency as of December 31, 2025, included in ARPU amounted to P$9,934.2 and P$20,015.7 as of December 31, 2024 and 2023, respectively. The customer base remained stable, which was a product of the Company’s efforts to maintain the customer base, considering the intense competition. Additionally, the churn rate per month amounted to 1.5% in 2024 and 1.8% in 2023. ARPU of Internet Services - ICT Services provided in Argentina - Personal Network A monthly operational measure used in the internet services is ARPU, which we calculate by dividing adjusted total service revenues - excluding connection and rehabilitation fees revenues and others - (divided by 12 months) by the average number of customers during the year. ARPU is not a measure calculated in accordance with IFRS Accounting Standards and our measure of ARPU may not be calculated in the same manner as similarly titled measures used by other companies. Certain components of service revenues are excluded from Internet’s ARPU calculations presented in this Annual Report. Management believes this measure is helpful in assessing the development of the subscriber base of internet services. The following table shows the reconciliation of total service revenues to such revenues included in the ARPU calculations of 2024 and 2023: Year ended December 31, Year ended December 31, 2024 2023 (P$ million) Total Internet service revenues 1,310,927 1,218,833 Components of service revenues not included in the ARPU calculation — — Adjusted total service revenues included in the ARPU calculation 1,310,927 1,218,833 Average number of customers during the year (millions) 4.0 4.1 ARPU of Internet service revenues in Argentina - ICT Services provided in Argentina - Personal Network 26,860.4 24,841.1 Cable Television Services Cable television service revenues amounted to P$789,469 million in 2024 (equivalent to 15.5% of total consolidated services revenues), decreasing P$251,452 million or 24.2% as compared to revenues in 2023. The effect generated by the restatement in current currency as of December 31, 2025, included in cable television services revenues amounted to P$294,146 million and P$844,987 million in 2024 and 2023, respectively. The decrease in cable television service revenues in 2024 was mainly due to the decrease in ARPU, a 26.3% decrease compared to 2023, partially offset by a 1.9% increase in the customer base compared to 2023. The ARPU amounted to P$18,143.6 for the year ended December 31, 2024, compared to an ARPU of P$24,610.8 for the year ended December 31, 2023. The decreased is mainly explained since inflation during 2024 amounted to 117.8%, the Company (and other competitors in the ICT industry) was unable to increase its prices during 2024 to the same extent as the increase in inflation (the effect generated by the restatement in current currency as of December 31, 2025 included in ARPU amounts to P$6,456.3 and P$19,991.6 as of December 31, 2024 and 2023, respectively). Additionally, greater commercial discounts have been applied as part of the customer retention strategy. As of December 31, 2024, the customer base for ICT Services provided in Argentina – Personal Network amounted to 3.2 million customers, increasing by 2.0% compared to 2023, leveraged by Flow Full and Flow Flex products, where from the third quarter of 2024, Flow Flex, began to be marketed as main product. Out of the total customers as of December 31, 2024, 1.5 million were Flow’s customer base and 1.1 million were Premium Package’s customer base, whereas as of December 31, 2023, 1.4 million were Flow’s customer base and 1.2 were Premium Package’s customer base. Additionally, the average churn rate per month amounted to 1.8% in 2024 and 2023. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 113 Table of Contents ARPU of Cable Television Services - ICT Services provided in Argentina – Personal Network An important monthly operational measure used in the Cable Television services is ARPU, which we calculate by dividing adjusted total service revenues - excluding connection and administration fees, advertising services and others - (divided by 12 months) by the average number of customers during the year. ARPU is not a measure calculated in accordance with IFRS Accounting Standards and our measure of ARPU may not be calculated in the same manner as similarly titled measures used by other companies.

The effect generated by the restatement in current currency as of December 31, 2024, included in fixed and data services revenues amounted to P$252,493 million and P$563,939 million in 2024 and 2023, respectively. The decrease in fixed and data services in 2024 was mainly due to a decrease in ARPU, decreasing 1.1% as compared to 2023, and a decrease in the customer base of 7.6% compared to 2023, partially offset by the appreciation of data service subscriptions that are agreed in U.S. dollars. The customer base of fixed telephony services amounted to 2.7 million (of which 1.9 million are IP fixed telephony service base) in 2024, compared to 2.9 million in 2023. The customer base decreased mainly due to changes in the consumption behaviour of customers. Other services revenues Other services revenues generated by other services amounted to $60,998 million in 2024, increasing $6,284 million or 11.5% compared to 2023. The effect generated by the restatement in current currency as of December 31, 2024, included in other services revenues amounted to $22,009 million and $43,845 million in 2024 and 2023, respectively. These services include mainly revenues related to Fintech Services, revenues from billing remuneration and collection management on behalf of third parties, administrative revenues and revenues from the sale of advertising space, among others. The increase in other services revenue in 2024 was mainly due to the increase in Fintech Services in Argentina, principally due to the growth in the use of the “Personal Pay” digital wallet and the increase in the number of users, which amounted to 3.6 million and 2.0 million in 2024 and 2023, respectively.

Despite being in a context in which year-on-year inflation was 117.8%, the Company has managed to make its operating costs more efficient and achieve a reduction. The effect generated by the restatement in current currency as of December 31, 2024, included in operating costs (without depreciation, amortization and impairment of Fixed and Intangible Assets) amounted to P$1,511,055 million and P$3,437,361 million in 2024 and 2023, respectively. Employee benefit expenses and severance payments Employee benefit expenses and severance payments decreased P$127,019 million to P$1,346,737 million in 2024 as compared to P$1,473,756 million in 2023. The decrease was mainly due to a reduction in headcount of 6.0%, amounting to 19,987 employees as of December 31, 2024, and, partially offset by increases in salaries agreed by the Company with several trade unions for unionized employees, and for non-unionized employees, together with related social security charges and an increase in severance payments. The effect generated by the restatement in current currency as of December 31, 2025, included in Employee benefit expenses and severance payments amounted to P$498,312 million and P$1,184,876 million in 2024 and 2023, respectively.

Adjusted EBITDA An important operational performance measure used by the Company’s Chief Operating Decision Maker (as this term is defined in IFRS Accounting Standards 8) is Adjusted EBITDA. Adjusted EBITDA is defined as our net income (loss), less income tax, financial results, earnings (losses) from associates and joint ventures, and depreciation, amortization and impairment of Fixed and Intangible Assets. We believe Adjusted EBITDA facilitates company-to-company operating performance comparisons by backing out potential differences caused by variations such as capital structures, taxation and the useful lives and book depreciation and amortization of PP&E and intangible assets, which may vary for different companies for reasons unrelated to operating performance. Although Adjusted EBITDA is not a measure defined in accordance with IFRS Accounting Standards (a non-GAAP measure), our Management believes that this measure facilitates operating performance comparisons from period to period and provides useful information to investors, financial analysts and the public in their evaluation of our operating performance. Adjusted EBITDA does not have a standardized meaning and, accordingly, our definition of Adjusted EBITDA may not be comparable to Adjusted EBITDA as used by other companies. The following table shows the reconciliation of Net income (loss) to Adjusted EBITDA: Year ended December 31, 2024 2023 Total Change (P$ million) % (P$ million) Net income (loss) 1,359,230 (715,266) n/a 2,074,496 Income tax loss (benefit) 538,237 (968,990) n/a 1,507,227 Other financial results, net (190,451) (496,492) (61.6) 306,041 Financial results from borrowings (1,914,786) 1,817,071 n/a (3,731,857) Losses from associates and joint ventures 15,094 5,408 n/a 9,686 Operating loss (192,676) (358,269) (46.2) 165,593 Depreciation, amortization and impairment of Fixed and Intangible Assets 1,725,057 2,018,038 14.5 (292,981) Adjusted EBITDA 1,532,381 1,659,769 (7.7) (127,388) Our consolidated Adjusted EBITDA amounted to P$1,532,381 million in 2024, representing a decrease of P$127,388 million or 7.7% as compared to P$1,659,769 million in 2023.

Financial Results, net in 2024 mainly include gain generated by (i) foreign exchange differences measured in real terms of P$2,467,139 million as a result of the U.S. dollar appreciating 27.7% against the Argentine Peso compared to a 117.8% inflation (compared to a loss of P$1,961,176 million in 2023 and 356.3% devaluation of the Argentine Peso against the U.S. dollar compared to a 211.4% inflation in 2023) and (ii) the effect generated by the restatement in current currency, which amounted to a gain of P$170,007 million (compared to P$538,038 million in 2023). These gains were partially offset by losses generated by (i) interest on borrowings measured in real terms of P$173,837 million (compared to P$167,520 million in 2023), (ii) remeasurement in borrowings of P$135,137 million (compared to a gain of P$142,649 million in 2023), (iii) other financial results of P$163,212 million (compared to P$56,833 million in 2023), and (iv) fair value losses on financial assets at fair value through profit or loss of P$59,723 million (compared to a gain of P$184,263 million in 2023). Other financial results include the effect of PAIS tax of P$75,143 million in 2024. Income Tax The Company’s income tax charge includes the following effects: (i) the current tax payable for the year pursuant to tax legislation applicable to each of Telecom Argentina and its subsidiaries; (ii) the effect of applying the deferred tax method on temporary differences arising out of the asset and liability valuation according to tax versus financial accounting criteria and; (iii) the effects of the income tax inflation adjustment. Income tax amounted to a loss of P$538,237 million in 2024 as compared to a gain of P$968,990 million in 2023. It includes mainly the following effects: (i) regarding current tax expenses, Telecom’s generated tax loss in fiscal year 2024 amounting to P$14,344 million and tax loss in fiscal year 2023 amounting to P$8,305 million, and (ii) regarding the deferred tax, in 2024 Telecom recorded a deferred tax loss of P$523,893 million compared to a deferred tax gain of P$977,295 million in 2023. For more information on income tax, see Notes 3 and 16 to our Consolidated Financial Statements. Net income (loss) Telecom Argentina recorded a net income of P$1,359,230 million in 2024 as compared to a net loss of P$715,266 million for 2023 and represents 25% of consolidated revenues as compared to (12.1) % in 2023. The increase in net income was mainly due to the income before income tax of P$1,897,467 million, partially offset by the income tax loss amounting to P$538,237 million. Net income attributable to controlling shareholders amounted to P$1,331,805 million in 2024 as compared to a net loss of P$738,306 million in 2023. Liquidity and Capital Resources Sources and Uses of Funds We expect the main sources of Telecom Argentina’s liquidity in the short term to be cash flows from Telecom Argentina’s operations and cash flows from financing from third parties, which may include accessing to domestic and international capital markets and obtaining financing from financial institutions. Telecom Argentina’s principal uses of cash flows are expected to be capital expenditures, operating expenses, dividend payments to its shareholders, payments of borrowings and for general corporate purposes. Telecom Argentina expects working capital, funds generated from operations, dividend payments from its subsidiaries and financing from third parties to be sufficient.

The decrease was primarily due to an increase in trade payable payments, mostly due to settlements of outstanding foreign currency payables (which also were settled using government bonds), an increase in payments of salaries and social security payables, partially offset by an increase in cash flows related to trade receivables and other receivables. Cash flows used in investing activities were P$3,011,630 million, P$504,380 million and P$1,631,680 million in 2025, 2024 and 2023, respectively.

Our ability to generate sufficient cash from our operations to satisfy our indebtedness and capital expenditure needs may be affected by macroeconomic factors influencing our business, including, without limitation, the rate at which Argentine Pesos can be exchanged for U.S. dollars and rates of inflation, among others. Certain statements expressed in this section constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and involve risks and uncertainties, including those described in this Annual Report in “Item 3—Key Information—Risk Factors.” Actual results may differ materially from our expectations described above as a result of various factors. Capital Expenditures We estimate that our capital expenditures in 2026 will be approximately P$2,111,085 million, compared to P$1,485,577 million in 2025 (which represented 17.8% of our consolidated revenues). The primary investment projects in PP&E are related to the expansion of cable television and internet services, aimed at improving transmission and access speed for customers, the deployment of 4G coverage and capacity, and the continued expansion of 5G to support mobile internet growth and enhance service quality. ICT Services provided in Argentina – Personal Network In terms of infrastructure, throughout 2025, we continued to enhance the services we provide through the deployment of the 4G/LTE network, together with the technological reconversion of our 2G / 3G networks to 4G and LTE and the deployment of fiber optics to connect homes with broadband, which also improved our fixed and data networks. The deployment of 4G/LTE reached a coverage of 97% of the urban population, and we achieved a coverage of 98% of the population in Argentina’s major cities. Our mobile network customers with access to our 4G network, according to the latest benchmark conducted by Ookla, experience improved service quality, with average speeds of 78 Mbps in 2025 and 2024. Additionally, approximately 85% of calls are made via VoLTE, a technology that enables voice calls over the 4G network with significant improvements in audio and video quality. During 2025, the Company continued the expansion of its 5G network, incorporating 819 new sites. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 126 Table of Contents Furthermore, we continued deploying mobile site connectivity to achieve better quality and capacity, replacing radio links with high-capacity fiber optic connections. Lastly, we continued with the plan to connect remote and low-density areas through satellite backhaul. ICT Services provided in Argentina – TMA Network In terms of fixed access infrastructure, during 2025 TMA continued strengthening its broadband capabilities through the deployment of new fiber optic networks and the modernization of existing infrastructure. These initiatives were oriented toward improving service quality, expanding high-speed access and enhancing the overall customer experience. Throughout the year, TMA advanced the rollout of FTTH in new residential areas, buildings and commercial zones, deploying more than 350,000 new homes passed across over 11,000 city blocks. Approximately half of this expansion was carried out in the Buenos Aires Province, reinforcing TMA’s presence in regions with strong demand for broadband services. TMA also progressed with the modernization of its access network by replacing legacy platforms, including the renewal of multiple OLTs, incorporating technology capable of supporting XGSPON and 50GSPON evolution paths. In parallel, through strategic partnership agreements, TMA added an additional 170,000 homes passed, complementing its own deployment and enabling broader network reach. As a result, by the end of 2025 TMA’s total footprint totals approximately 5.2 million homes passed, with 4.15 million on its own network and 1.05 million through partner networks. Also, TMA continued to improve the services we provide by deploying the 4G/LTE and 5G networks. This allowed TMA to stand out from its competitors, significantly improving the NPS of its customers. The deployment of 4G/LTE has achieved a coverage of 99,4 % of the urban population across 2,218 towns and cities as of December 31, 2025. Furthermore, TMA has reached a 100 % coverage of the population in major cities of Argentina, as of December 31, 2025. Customers who access TMA’s 4G network experience enhanced service quality, enjoying speeds of up to 66 Mbps and, approximately 53% of calls are now made using VoLTE. In addition, TMA continued the deployment of mobile site connectivity to enhance quality and capacity, replacing radio links with high-capacity fiber optic connections. See “Item 3—Key Information—Risk Factors—Risks Relating to Telecom and its Operations—We operate in a highly competitive environment that could materially erode our market position.” We expect to finance our capital expenditures through cash generated from our operations, cash on hand and financing from third parties; therefore, our ability to fund these expenditures is dependent on, among other factors, our ability to generate sufficient funds from operations. Telecom’s ability to generate sufficient funds for capital expenditures is also dependent on its ability to increase its service prices, the increase of its operating costs due to inflation and the increase of the cost of imported materials in Argentine Peso terms as a result of the devaluation of the Peso/U.S. dollar. Research and Development, Patents and Licenses, etc. None. Trend Information During 2025, Telecom Argentina continued its strategy of consolidation as a relevant player within the Argentina’s digital ecosystem, combining connectivity, technology services, and entertainment. As part of this consolidation process, the Company moved forward with the unification of its brand identity under Personal as as the brand that integrates all its solutions and platforms. This strategic decision allows for a simpler value proposition, strengthens the consistency of the customer experience, and enhances commercial and operational synergies across the different business verticals. By consolidating a robust, cross-cutting brand, the Company reinforces its positioning as an integrated digital ecosystem through Personal Móvil, Personal Fibra, Personal Smarthome, Tienda Personal, Personal Flow, Personal Tech and Personal Pay, expanding its ability to scale high value-added solutions for all customers. PART I - ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS TELECOM ARGENTINA S.A. 127 Table of Contents In an environment showing improved investor confidence and a recovery in strategic sectors, the Company reaffirms its commitment to the development of capabilities that support the country’s digital economy. Leveraging its comprehensive service offering and an active investment policy, the Company advanced the expansion and modernization of its infrastructure, supporting the evolution of digital demand with a focus on efficiency, quality, and technological capacity. This approach is grounded in a long-term vision that integrates sustainability, innovation, and digital transformation as strategic pillars. One of the most significant milestones of the year was the acquisition of TMA, completed on February 24, 2025, for US$1,245 million (“consideration paid” pursuant to IFRS 3 was US$1,119 million). This transaction—one of the largest private infrastructure investments executed in the country during the period—reflects Telecom’s commitment to the development of strategic capabilities for the digital economy, in line with a global trend of transformation and consolidation within the telecommunications industry. Telecom Argentina is currently engaged in institutional dialogue with the relevant regulatory authorities, supporting a technical review in compliance with international standards and competition principles. In this context, the CNDC (currently ANC) ordered a provisional measure requiring that the two companies remain operationally separate until the competent authority issues its decision on the transaction. Accordingly, Telecom Argentina and TMA continue to operate as separate legal entities and independent businesses. Another key milestone in 2025 and January 2026, was the successful issuance of international Notes (Series 24 and Series 27) for US$1,000 million and US$600 million, respectively. These transactions strengthen the Company’s financial position and support its growth strategy in line with current and future technological challenges. During the year, the Company received international recognitions for its financial management, innovation capabilities, and technological leadership. At the 2025 LatinFinance Project & Infrastructure Finance Awards, the Company received the Telecoms Financing of the Year award in recognition of its long-term financial strategy, as well as the Corporate Liability Management of the Year award for the successful refinancing and reopening of international bonds completed in 2024. The Company also received first place at the ASUG 2025 Awards for its Financial Planning Transformation project, based on predictive models and the in-house use of big data. The Company’s sustained deployment of connectivity infrastructure also received international recognition.

Personal Flow reinforced its positioning in the entertainment services by adding services that enhance the customer experience, such as Flow Plus, as well as co-productions and live concert streaming. Personal Pay continued to strengthen its presence within the regional fintech ecosystem. A strategic alliance with Banco Macro was recently announced to accelerate the digitalization of financial services offered through Personal Pay. This partnership will enable Personal Pay to offer customers a unique value proposition that combines the practicality of a digital wallet with expanded access to financial products and services backed by a leading bank. Through Personal Tech, the Company continued to develop its value proposition for B2B services offering tailored and scalable solutions for enterprise customers, supported by a solutions portfolio built on: fixed and mobile connectivity, cybersecurity, cloud solutions, and IoT.
