TRANSPORTADORA DE GAS DEL SUR S.A.

ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (“MD&A”) FOR THE NINE-MONTH PERIOD ENDED SEPTEMBER 30, 2024

The following discussion of the financial condition and results of operations of the Company should be read in conjunction with the Company's consolidated financial statements as of September 30, 2024 and December 31, 2023, and for the nine-month periods ended September 30, 2024 and 2023. These condensed interim consolidated financial statements have been prepared in accordance with and complied with IAS 34 issued by the International Accounting Standards Board (“IASB”) adopted by the Comisión Nacional de Valores ("CNV") through the provisions of Title IV, Chapter I, Section I, Article 1 – B.1 of the Rules of the CNV ("New Text 2013" or "NT 2013").

The condensed interim consolidated financial statements of the Company for the nine-month periods ended September 30, 2024, 2023, 2022, 2021 and 2020 have been subject to a limited review performed jointly by Price Waterhouse & Co. S.R.L. and Pistrelli, Henry Martin and Asociados S.A.

Effects of inflation

On December 3, 2018, Law No. 27,468 was enacted, sanctioned on November 15, 2018, by the National Argentine Congress. Among other measures, this law abolishes Presidential Decree No. 1,269/02 —amended by Presidential Decree No. 664/2003 — through which the controlling entities (among them the CNV) had been instructed not to accept inflation adjusted financial statements. On December 26, 2018, the CNV issued Resolution No. 777/2018, by virtue of which it instructs companies that offer their shares to the public to apply the financial statements restatement method to a stable currency in line with the provisions of IAS 29 “Financial Reporting in Hyperinflationary Economies”.

In accordance with such standards, the restatement of financial statements was restarted as from July 1, 2018. In line with the restatement method, non-currency assets and liabilities are restated by an overall price index issued by the Argentine Federation of Professional Councils in Economic Sciences (“Argentine Federation”) since their acquisition date or last inflation adjustment (March 1, 2003).

Likewise, comparative information included in the financial statements has also been restated, but this fact has not modified the decisions based on the financial information corresponding to those fiscal years.

For further information, see “Note 4. Significant Accounting Policies – d) Restatement to current currency – Comparative Information” to the consolidated financial statements as of December 31, 2023.

Rounding

Certain figures included in this Report have been rounded for ease of presentation. Percentage figures included in this Report have not, in all cases, been calculated on the basis of such rounded figures but on the basis of such amounts prior to rounding. For this reason, percentage amounts in this report may vary from those obtained by performing the same calculations using the figures in our Financial Statements. Certain numerical figures shown as totals in some tables may not be an arithmetic aggregation of the figures that preceded them due to rounding.

1.Results of operations

The following table presents a summary of the consolidated results of operations for the nine-month periods ended September 30, 2024 (“9M2024”) and September 30, 2023 (“9M2023”):

Activities of the Company in 9M2024 and 9M2023

Revenues

Revenues for 9M2024 increased by Ps. 100,282 million compared to 9M2023, mainly due to the increase in revenues from Natural Gas Transportation and Midstream business segments.

Natural Gas Transportation

During 9M2024 revenues from the Natural Gas Transportation business segment accounted for 35% of tgs total revenues (22% for 9M2023). 84% of total revenues in this segment corresponded to firm contracted capacity services (82% for 9M2023).

Revenues from the Natural Gas Transportation segment during 9M2024 reached Ps. 284,177 million (Ps. 158,631 million in 9M2023). The increase of Ps. 125,547 million was primarily driven by the positive impact of transitional tariff increases received during 2024, as explained below. This effect was partially offset by the negative impact of inflation adjustment.

On March 26, 2024, the Issuer and ENARGAS entered into a Tariff Transitory Adjustment Agreement (the “Tariff Agreement”), which provides for a 675% transitional adjustment in natural gas transportation tariffs effective as of April 3, 2024, pursuant to Resolution No. 112/2024 issued by ENARGAS (“Resolution 112”). Resolution 112 provides that, as from May 2024 and until ENARGAS’s integral tariff review process for the natural gas industry is completed, tariffs are adjusted monthly based on a composite index (the “Transitional Adjustment Index”) by the wage index, the wholesale price index and the construction cost index.

During the following months, ENARGAS notified the licensee companies of the postponement of previously scheduled monthly adjustment. Additionally, it announced that the Transitional Adjustment Index would be replaced by an adjustment index based on expected inflation to be communicated by the Ministry of Economy. The difference between actual and estimated inflation will be considered in the RTI tariff calculation. According to the notification received, if the actual inflation is higher or lower than the inflation estimated by the Ministry of Economy, this difference will be taken into account when determining the tariff resulting from the RTI process.

On August 1, September 2, October 1 and November 4, 2024 ENARGAS issued new transition tariff charts contemplating increases of 4%, 1%, 2.7% and 3.5%, respectively, over the tariff in effect at the time.

In addition, Resolution 112 provides that during 2024 tgs must execute an investment plan in the amount of Ps. 27,690 million (adjustable by the Transitional Adjustment Index), which, as of the date hereof, is in the process of execution.

License extension request

In relation to the extension of the License, on June 19, 2024, ENARGAS issued a technical and legal report indicating that we have broadly fulfilled our obligations regarding the License. Based on this report, and after a non-binding public hearing, the ENARGAS controller may submit a recommendation to the National Executive Branch which, in turn, may issue a decree granting the extension of the License within 120 days from the date of the recommendation.

Finally, on October 21, 2024, the aforementioned public hearing took place, convened by ENARGAS through Resolution No. 593/2024. As of the date of issuance of this MD&A, the ENARGAS controller has not issued the aforementioned recommendation.

Liquids Production and Commercialization

During 9M2024, revenues corresponding to this business segment represented 48% of total revenues (60% for 9M2023).

Revenues derived from the Liquids Production and Commercialization business segment amounted to Ps. 367,991 million in 9M2024 (Ps 55,268 million lower than those recorded in 9M2023). This negative effect was mainly due to the decrease in: (i) tons of ethane dispatched, (ii) the price of the ethane and (iii) the volumes of propane, butane and natural gasoline. These effects were partially offset by the positive variation in the real exchange rate, the improvements in the premiums corresponding to the export of propane and butane and in the international reference prices.

Total volumes dispatched registered a decrease of 14% or 119,596 tons compared to 9M2023.

Midstream

Revenues derived from the Midstream business segment increased by Ps. 30,003 million in 9M2024 compared to the same period of 2023. This increase is due to higher revenues corresponding to: (i) natural gas transportation and conditioning services in Vaca Muerta and (ii) the positive variation in the real exchange rate.

On June 19, 2024, tgs submitted an investment proposal to the Ministry of Economy under a private initiative framework to increase the available volume of natural gas in the northeast area of Argentina by the winter of 2026. The Investment Proposal seeks to replace natural gas and liquid imports each winter by using existing infrastructure.

This proposal would be executed as a complement to the construction of stage 2 of the GPNK, presenting itself as an alternative through the use of existing infrastructure, with the objective of achieving the lowest cost for the end user and savings for the National Government If approved by the Government, a bidding process will be initiated, where we will have the option to match the best offer made by a third party to the Government. As of the date of this MD&A, no response has been received from the National Government.

During October, the first module was put into operation, increasing the conditioning capacity of the Tratayén plant by 6.6 MMm3/d, reaching a total capacity of 21.4MMm3/d. It should be noted that the total work, which will require an investment of approximately US$ 350 million, will allow

tgs to have a total conditioning capacity of 28MMm3/d by the end of 2024, when the last module that is currently in the installation process finally comes into operation.

Cost of sales and administrative and selling expenses

Cost of sales, administrative and selling expenses corresponding to 9M2024 decrease by Ps. 46,047 million. This variation is mainly due to the decrease in the cost of natural gas processed at the Cerri Complex (mainly due to a decrease in the price, measured in constant Argentine pesos). This effect was partially offset by the increase in (i) third-parties fees and services and repair and maintenance expenses, (ii) taxes, fees and contributions (mainly due to the effect of the higher charge on gross income and withholdings on exports) and (iii) labor costs.

The following table shows the main components of cost of sales, administrative and selling expenses, and comparisons for 9M2024 and 9M2023:

Financial results

In 9M2024, the financial results experienced a positive effect of Ps. 24,096 million with respect to same period of 2023. The breakdown of financial results is as follows:

This positive variation is mainly due to the lower negative foreign exchange loss. This effect was partially offset the lower positive financial results recorded by financial assets due to the decrease in the returns obtained and the higher loss on net monetary position.

2.Liquidity

The Company’s primary sources and application of funds during 9M2024 and 9M2023 are shown in the table below:

During 9M2024 the net variation in cash and cash equivalents was positive by Ps. 36,677 million.

Cash flow provided by operating activities amounted to Ps. 294,830 million. This cash flow was Ps. 18,370 million higher than in 9M2023 due to higher working capital and lower income tax paid. These effects were partially offset by higher interests paid.

Cash flows used in investing activities amounted to (Ps. 248,872) million, Ps. 41,861 million lower than funds used in 9M2023 due to lower collections of placements of funds not considered cash equivalents according to IFRS Accounting Standards.

Finally, cash flows used in financing activities during 9M2024 amounted to Ps. 9,281 million while during 9M2023 financing activities provided cash flows of Ps. 34,868 million. During 9M2024, the Company incurred new short-term financial debt for Ps. 60,870 million and repayments were made for Ps. 79,051 million.

It is noteworthy that on July 24, the placement of Class 3 Notes was carried out for an amount of US$ 490 million. These notes with amortization on July 24, 2031, pay semiannual interest at a fixed interest rate of 8.5% per year. The total amount received, after deducting the issue price, amounted to US$ 483 million and was allocated entirely to the cancellation of the notes whose maturity was on May 2, 2025.

3.Third Quarter 2024 (“3Q2024”) vs. Third quarter 2023 (“3Q2023”)

The following table presents a summary of the consolidated results of operations for the 3Q2024 and 3Q2023:

During 3Q2024, the Company obtained comprehensive income of Ps. 52,188 million, compared to comprehensive income of Ps. 15,077 million obtained in the same period of 2023.

Total revenues for 3Q2024 increased Ps. 25,992 million compared to the same period of the previous year.

Revenues from the Natural Gas Transportation business segment in 3Q2024 increased by Ps. 70,917 million, compared to 3Q2023. This positive variation was due to the impact of the tariff increases granted during 2024.

As for the Liquids Production and Commercialization business segment, revenues decreased by Ps. 43,226 million in 3Q2024, mainly due to the drop in (i) the volume and price of ethane sold, (ii) the impact of the exchange rate on sales denominated in US dollars and (iii) the volumes of natural gasoline, propane and butane dispatched. These effects were partially offset by the increase in international reference prices.

With respect to the total volumes dispatched from the Cerri Complex, which decreased by 23% or 60,308 tons, the table included below shows the volumes dispatched by market and product and revenues by market:

The Midstream business segment reported a decrease of Ps. 1,699 million, mainly explained by

the fall in the exchange rate in real terms and lower services from the Transport.Ar program. These effects were partially offset by greater natural gas transportation and conditioning services in Vaca Muerta.

Net cost of sales, administrative and selling expenses for 3Q2024 amounted to Ps. 151,745 million (compared to Ps. 176,304 million in 3Q2023), a decrease of Ps. 24,559 million. This variation is mainly due to lower costs of natural gas processed at Cerri Complex (lower price expressed in constant currency and lower consumption). This effect was partially offset by higher repair and maintenance expenses of PPE and labor costs.

The following table shows the main components of operating costs, administrative and commercialization expenses and their main variations for 3Q2024 and 3Q2023:

In 3Q2024, financial results suffered a negative variation of Ps. 11,468 million, compared to those registered in the 2023 period. This variation is mainly due to the lower positive result generated by financial assets, effect thar was partially offset due to the lower negative exchange rate difference (because of the greater variation in the exchange rate during 3Q2024).

10.Outlook

The future of natural gas as an essential fuel for the country's energy matrix is consolidated year after year, which will make Argentina a sustainable country with high growth. We have consolidated ourselves as an integrated service provider in the hydrocarbon industry.

Our strategy aims to position ourselves in a leading role, carrying out vital undertakings for the future of the country, thus consolidating the growth strategy with a leap of magnitude. With this objective, we are adopting an innovative vision, seeking new business opportunities for our clients with a focus on Vaca Muerta.

Continuing our growth plan in the area, we expect, by the last quarter of 2024, the culmination of the expansion of the Tratayén conditioning plant through the installation of the remaining conditioning module of 6.6 million m3/day. The total investment made for the installation of this module and the one currently in operation, mentioned above, will amount to US$350 million.

The current economic situation and the tariff review process faced by the authorities implies that we must continue to generate valid and constructive channels of dialogue that allow us to manage a profitable and efficient natural gas transportation business in accordance with the country's energy development, considering the needs of the internal and external demands and of our stakeholders.

In this framework, we will be attentive to the talks with the national authorities in order to advance in the concretion of the new RTI process.

In the Liquids Production and Commercialization Segment, the strategy will be aimed at optimizing the production mix that allows prioritizing those products and distribution channels that provide higher margins, and to maximizing access to the RTP at reasonable costs. For this, it will be very important to be efficient in the management of our assets, ensuring a coordinated, safe and efficient operation.

In financial terms, and given the aforementioned facts, we will continue to prudently manage our funds in order to preserve our shareholders´ value given the volatile macroeconomic context in which our activities will be carried out.

As regards their daily operations, tgs will remain committed to continuous improvement of each of its processes to optimize the use of the resources and to reduce operating costs. To this end, the Company will carry out actions aimed at the reduction of cost without affecting the reliability and availability of the pipeline system. We will continue with the implementation of various actions, such as the standardization and systematization of risk management in pipelines, compressor stations and processing facilities. Finally, we will deepen training initiatives for the staff for technical and management training resources.

1.GENERAL INFORMATION

Business Overview

Transportadora de Gas del Sur S.A. (“tgs” or the “Company”) is one of the companies created as a result of the privatization of Gas del Estado S.E. (“GdE”). tgs commenced operations on December 28, 1992 and it is mainly engaged in the Transportation of Natural Gas, and Natural Gas Liquids Production and Commercialization (“Liquids”). TGS’s pipeline system connects major natural gas fields in southern and western Argentina with natural gas distributors and industries in those areas and in the greater Buenos Aires area. The natural gas transportation license to operate this system was exclusively granted to TGS for a period of thirty-five years (“the License”). TGS is entitled to a one-time extension of ten years provided that it has essentially met the obligations imposed by the License and by Ente Nacional Regulador del Gas (National Gas Regulatory Body or “ENARGAS”). The General Cerri Gas Processing Complex (the “Cerri Complex”), where TGS processes natural gas to obtain liquids, was transferred from GdE along with the gas transmission assets. TGS also provides midstream services, which mainly consist of gas treatment, removal of impurities from the natural gas stream, gas compression, wellhead gas gathering and pipeline construction, operation and maintenance services. In addition, telecommunications services are provided through the subsidiary Telcosur S.A. (“Telcosur”). These services consist of data transmission services through a network of terrestrial and digital radio relay.

Subsequently, the corporate purpose of the Company was modified in order to incorporate the development of complementary activities, incidental, linked and / or derived from natural gas transportation, such as the generation and commercialization of electric power and the provision of other services for the hydrocarbon sector in general.

Major Shareholders

tgs´ controlling shareholder Compañía de Inversiones de Energía S.A. (“CIESA”), holds 51% of the common stock of the company, the National Social Security Administration (“ANSES”) holds 24% and the remaining 25% is held by the investing public (tgs has 5.25% of the shares in the portfolio).

CIESA is under joint control of: Pampa Energía S.A. (“Pampa Energía”) with 50% and Grupo Inversor Petroquímica S.L. (“GIP S.L.”) and PCT L.L.C. with the remaining 50%.

Economic context

The Company operates in a complex economic context whose main variables have recently had strong volatility as a result of political and economic events at the national level.

Although after the new government took office in December 2023, certain restrictions were eased and other changes are expected, the context of volatility and uncertainty continues as of the date of issuance of these interim condensed consolidated financial statements. Government measures already implemented, or those that may be implemented in the future, regarding restrictions for the payment of imports of goods and services from abroad, could eventually limit tgs' ability to access inputs, capital goods and services. necessary for its operations. Furthermore, the application of existing foreign exchange regulations remains uncertain and the scope and timing of upcoming changes are unknown.

After six months of debate in the National Congress, on June 28, 2024, the Chamber of Deputies sanctioned the final text of the Bases Law, which had previously obtained half a sanction from the Chamber of Senators. Among other issues, the Bases Law includes:

·The declaration of public emergency in administrative, economic, financial and energy matters for one year period.

·Modifications in the calculation of income tax for individuals, in the Simplified Tax Regime for Small Taxpayers, personal assets and money laundering.

·The privatization, whether total or partial, of certain companies and societies owned wholly or majority by the national state is authorized.

·A Large Investment Incentive Regime (RIGI) for projects that involve certain conditions.

·The creation of a proportional retirement benefit for those people who, upon reaching retirement age, do not reach the necessary years of pension contributions.

·A labor reform and retirement regime.

·The amendment to the Natural Gas Law in order to, among other points, allow the extension of the License for an additional period of 20 years (as opposed to the originally established 10-year extension).

Although some of the reforms proposed by the Base Law have already been implemented, others are in the process of regulation and legislative discussion. For this reason, at the date of issuance of these interim condensed consolidated financial statements, it is not possible to foresee the impact that the Base Law and the fiscal package could have on the financial situation and results of the Company's operations.

The Company's Management permanently monitors the evolution of the situations that affect its business, to determine the possible actions to be taken and to identify the possible impacts on its financial situation and the results of its operations. The Company's financial statements must be read considering all these circumstances. Likewise, the Company cannot guarantee that the aforementioned macroeconomic difficulties or the adoption of new measures by the Argentine Government to control inflation may affect its operations and financial situation.

5.FINANCIAL RISK MANAGEMENT

The Company’s activities and the market in which it operates expose it to a series of financial risks: market risk (including foreign exchange risk, interest rate risk, and commodity price risk), credit risk and liquidity risk.

There were no significant changes since the last annual closing in the risk management policies.

Due to the main impacts of the described situation detailed in Note 1 to these condensed interim consolidated financial statements, the Company has implemented a series of measures that will mitigate its impact. In this sense, the Company's Management constantly monitors the evolution of the situations that affect its business, to determine the possible actions to be taken and to identify the possible impacts on its equity and financial position. The Company's financial statements should be read under the light of these circumstances.

6.CRITICAL ACCOUNTING ESTIMATES

The preparation of the Condensed Interim Consolidated Financial Statements in conformity with professional accounting standards requires the Company to make accounting estimates that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed interim financial statements and the reported amounts of revenues and expenses during the reporting period.

The making of such estimates involves tgs using assumptions and presumptions that are based on a number of factors, including past trends, events known at the date of issuance of these financial statements, and expectations of future events and their outcomes.

_____________________________________________________________________________________________________

As mentioned in Note 17.a. to the Consolidated Financial Statements as of December 31, 2023, the Company is jointly carrying out a new Comprehensive Tariff Review (“RTI”) process together with ENARGAS, which will culminate once the necessary regulations are issued to grant a tariff framework in accordance to the license with which it operates.

In the Natural Gas Transportation segment, the Company considered scenarios taking into account the transitional tariff regime and the new estimates of macroeconomic variables. Likewise, the Company updated its assessment of impairment indicators in accordance with IAS 36 as of September 30, 2024.

The conclusion of said evaluation was that no new factors were identified that negatively affect the premises underlying the recoverable value of the assets included within PPE, with respect to the last evaluation carried out, as of December 31, 2023.

Based on the above, the Company has determined that it is not necessary to record an additional impairment charge.

7.SUPPLEMENTAL CASH FLOW INFORMATION

For purposes of the condensed interim consolidated statement of cash flows, the Company considers all highly liquid temporary investments with an original maturity of three months or less at the time of purchase to be cash equivalents. The cash flow statement has been prepared using the indirect method, which requires a series of adjustments to reconcile net income for the period to net cash flows from operating activities.

Non-cash investing and financing activities for the nine-month periods ended September 30, 2024 and 2023 are presented below:

Note 14 includes a reconciliation between the opening and closing balance of the financial liabilities arising from financing activities.

8.CONSOLIDATED BUSINESS SEGMENT INFORMATION

IFRS Accounting Standard 8 “Operating Segments” (“IFRS 8”) requires an entity to report financial and descriptive information about its reportable segments, which are operating segments or aggregations of operating segments that meet specified criteria. Operating segments are components of an entity about which separate financial information is available that is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing performance. The Company’s CODM is the Board of Directors.

The Company analyzes its businesses into four segments: (i) Natural Gas Transportation Services, subject to ENARGAS regulations, (ii) Liquids Production and Commercialization, (iii) Midstream, and (iv) Telecommunications. These last three business segments are not regulated by ENARGAS. Liquids Production and Commercialization segment is regulated by the Secretary of Energy.

17.2 Fair value measurement hierarchy and estimates

According to IFRS Accounting Standard 13, the fair value hierarchy introduces three levels of inputs based on the lowest level of input significant to the overall fair value. These levels are:

·Level 1: includes financial assets and liabilities whose fair values are estimated using quoted prices (unadjusted) in active markets for identical assets and liabilities. The instruments included in this level primarily include balances in mutual funds and public or private bonds listed on the Bolsas y Mercados Argentinos S.A. (“BYMA”).

·Level 2: includes financial assets and liabilities whose fair value is estimated using different assumptions quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (for example, derived from prices).

·Level 3: includes financial instruments for which the assumptions used in estimating fair value are not based on observable market information.

The table below shows different assets at their fair value classified by hierarchy as of September 30, 2024:

The fair value amount of the financial assets is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

19.REGULATORY FRAMEWORK

The main regulatory issues are described in Note 17 to the annual consolidated financial statements as of December 31, 2023. As of the date of issuance of these Interim Condensed Consolidated Financial Statements, there were no additional developments except for the following:

Natural gas transportation transitional tariff increase

On March 26, 2024, tgs entered the 2024’s Transitional Agreement with the ENARGAS, which provides for a transitional 675% increase in natural gas transportation tariffs. This tariff increase came into effect on April 3, 2024, after Resolution No. 112/2024 (the “Resolution 112”) issued by ENARGAS was published in the Official Gazette. According to Resolution 112, as from May 2024 and until the RTI process is completed, tariffs are adjusted monthly according to the following formula (the "Transitional Adjustment Index"):

- 47.0% adjusted by the Wage Index - Registered Private Sector published by INDEC

- 27.2% adjusted by the Wholesale Price Index (“WPI”)

- 25.8% adjusted by the Construction Cost Index in Greater Buenos Aires - Materials chapter published by INDEC.

To this end, ENARGAS will issue the corresponding monthly resolution adjusting the tariff tables to be applied. On May 9, 2024, ENARGAS notified the licensee companies of the public natural gas transportation and distribution service of the postponement of the monthly tariff adjustment mentioned above.

On June 5, 2024, ENARGAS notified tgs that it will postpone the implementation of the tariff adjustment corresponding to the month of June 2024 and will also replace the monthly adjustment methodology planned for the months of July to December 2024 inclusive. According to the ENARGAS notification, the monthly tariff increase will be based on the expected inflation to be estimated by the Ministry of Economy for that period. The difference between the real and the estimated inflation will be considered in the RTI tariff calculation.

On July 1, ENARGAS once again informed the Company of the postponement of the monthly tariff increase, this time corresponding to the month of July, maintaining the tariff schedules in effect since April 3, 2024.

Effective as of August 1, September 2, October 1 and November 4, ENARGAS published new transition tariff tables that contained increases of 4%, 1%, 2.7% and 3.5%, respectively, on the rates in effect at that time.

In addition, Resolution 112 provides that during 2024 the Company must execute an investment plan in the amount of Ps. 27,690 million (adjustable by the Transitional Adjustment Index). As of the date of this Condensed Interim Consolidated Financial Statements, the Company has submitted such investment plan, which is in the process of execution.

Request for License Extension

On June 19, 2024, ENARGAS issued a technical and legal report indicating that tgs has broadly fulfilled its obligations regarding the License (the “License Report”). Based on the License Report and after a non-binding public hearing as required by Section 6 of the Natural Gas Law, the ENARGAS controller may submit a recommendation to the Executive Branch, which, in turn, may issue a decree granting the License within 120 days from the date of the recommendation.

c)Restrictions on distribution of retained earnings

Pursuant to the General Companies Act and CNV Rules, we are required to allocate a legal reserve (“Legal Reserve”) equal to at least 5% of each year’s net income (as long as there are no losses for prior fiscal years pending to be absorbed) until the aggregate amount of such reserve equals 20% of the sum of (i) “common stock nominal value” plus (ii) “inflation adjustment to common stock,” as shown in our consolidated statement of changes in equity.

As mentioned in subsection b of this note, the amounts subject to distribution are restricted up to the acquisition cost of treasury shares and the paid-up capital.

In accordance with current exchange regulations and in order to have access to the exchange market, for the payment of dividends to non-resident shareholders of Argentina, the Company must require the prior approval of the BCRA.
