ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS FOR THE NINE-MONTH PERIOD ENDED SEPTEMBER 30, 2020 (1)

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, 2020 and December 31, 2019, and for the nine-month periods ended September 30, 2020 and 2019. 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, 2020, 2019 and 2018 have been subject to a limited review performed jointly by Price Waterhouse & Co. S.R.L. ("Price") and Pistrelli, Henry Martin and Asociados S.R.L.

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 28, 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 constant currency – Comparative Information” to the consolidated financial statements as of December 31, 2019.

(0) Not covered by Auditor’s Report on Review of Interim Financial Information, except for items 4, 5, 6 and 8.

`1.`Results of operations

The following table presents a summary of the consolidated results of operations for the nine-month periods ended September 30, 2020 (“9M2020”) and September 30, 2019 (“9M2019”):

Activities of the Company in 9M2020 and 9M2019

Revenues

Revenues for 9M2020 decreased by Ps. 5,495 million from the same period last year. This decrease is mainly due to the decrease in revenues of the Liquids Production and Commercialization business segment.

Natural Gas Transportation

During 9M2020 revenues from the Natural Gas Transportation business segment accounted for 43% of TGS’ total net revenues (49% for 9M2019). 79% of the total revenues corresponded to firm contracted capacity services (82% for 9M2019).

Revenues from the Natural Gas Transportation segment during 9M2020 reached Ps. 16,541 million (Ps. 21,430 million in 9M2019). The decrease of Ps. 4,889 million is mainly due to the fact that the tariff rate increase granted by ENARGAS in April 2019 failed to offset the impact of inflation for the period between 9M2019 and 9M2020 on TGS’ rates. This effect was partially offset by higher natural gas deliveries under interruptible and exchange and displacement contracts.

Liquids Production and Commercialization

During 9M2020, the Liquids Production and Commercialization business segment represented 49% of TGS´ total revenues (45% for 9M2019).

Revenues derived from the Liquid Production and Commercialization segment amounted to Ps. 18,678 million in 9M2020 (Ps 1,261 million lower than those recorded in 9M2019). This decrease is due to fall in prices due to the effect of COVID-19. This effect was partially offset by higher volumes sold and the effect of the increase in the exchange rate on revenues denominated in US dollars.

Total volumes dispatched, in total terms, increased by 149,688 short tons (19%) compared to 9M2019.

2

The increase in the volumes dispatched is mainly due to the increase in deliveries of ethane after PBB Polisur SRL, the only customer to whom this product is commercialized, suffered in July 2019 technical problems in its facilities that prevented the normal supply of ethane Likewise, there was an increase in the volumes exported and in the butane sold in the local market assigned to the supply plans established by the Argentine Government.

The agreement regarding the commercialization of natural gasoline was successfully renewed. This agreement with Petrobras Global Trading B.V. will be extended for the period February 1, 2020 to January 31, 2021, and allows the Company to obtain improvements in the price.

Within the framework of the Households with Bottles Program by which butane is supplied to the local market, on October 19, 2020, the Secretary of Energy issued Resolution 30/2020 providing the increase of its price to Ps. 10,885 (10% increase over the current price as of September 30, 2020).

Other Services

Revenues derived from the Other Services segment increased Ps. 655 million in 9M2020 compared to the same period of 2019. This increase is due to higher revenues corresponding to transportation and conditioning services for natural gas in Vaca Muerta and the effect of the increase in the exchange rate on revenues denominated in US dollars. These effects were partially offset by lower construction services of the joint venture for the construction of a natural gas pipeline in the Province of Santa Fe ("UT SACDE - TGS") and natural gas compression and treatment services rendered.

Cost of sales and administrative and selling expenses

Cost of sales, administrative and selling expenses corresponding to 9M2020 decreased by Ps. 3,037 million, 12% compared to 9M2019. This variation is mainly due to the decrease in: (i) the cost of the natural gas processed in Cerri Complex (decrease in the price and quantities of natural gas purchased as Replacement of the Thermal Plant Reduction ("RTP"), (ii) in turnover tax and tax on exports, (iii) maintenance expenses and third party services and (iv) in labor costs. These effects were partially offset mainly by higher depreciations (due to the start-up of assets related to the provision of services in Vaca Muerta) and higher provisions for doubtful accounts.

Presidential Decree No. 488/2020 regulated the applicable tax rate on exports of certain oil and gas products, including those products that we export, establishing a range between 0% and 8% depending on the "ICE Brent first line" barrel price. If the mentioned price is below US$ 45 the rate will be zero. On the other hand, if the price is equal to or higher than US$ 60, an 8% rate will be paid, which will be variable if the price is between US$ 45 and US$ 60. Since this decree came into effect on May 19, 2020, the applicable export tax rate has been 0%.

The following table shows the main components of operating costs, administrative and commercialization expenses and comparisons for 9M2020 and 9M2019:

3

Other operating results

The other operating results recorded a positive variation of Ps. 202 million mainly as a result of the recognition of the collections received for insurance recovery and lower charges for provision for contingencies.

Net financial results

In 9M2020, the financial results showed a negative variation of Ps. 2,531 million with respect to 9M2019. The breakdown of net financial results is as follows:

The nominal exchange rate had a variation of Ps. 16.29 for each US dollar (27%) during 9M2020, as opposed to Ps. 19.89 for each US dollar (53%) during 9M2019.

`2.```Liquidity

The Company’s primary sources and application of funds during 9M2020 and 9M2019 are shown in the table below:

4

Net cash flow used in investing activities suffered a positive variation of Ps. 4,736 million mainly due to lower funds for the acquisition of capital goods after the completion of the works related to the midstream business in Vaca Muerta and as a consequence of the impact of COVID-19, partially offset by higher acquisitions of financial assets non considered cash and cash equivalents.

Regarding the net cash flow used in financing activities, it reduced by Ps. 9,612 million as a consequence of the dividend payment made in 9M2019. This effect was partially offset by the increase in: (i) the payments made for the acquisition of treasury shares, (ii) the cancellation of financial debts and (iii) the repurchase of our negotiable obligations.

On the other hand, the net cash flow provided by the operating activities showed an increase of Ps. 10,009 million, mainly derived from lower income tax payments, higher collections received from derivative financial instruments and improvements in the working capital.

`3.`Third quarter 2020 (“3Q2020”) vs Third quarter 2019 (“3Q2019”)

The following table presents a summary of the consolidated results of operations for 3Q2020 and 3Q2019:

During 3Q2020, total income amounted to Ps. 391 million, compared to Ps. 58 million for 3Q2019.

Total revenues increased Ps. 340 million in 3Q2020 compared to 3Q2019.

Revenues from the Natural Gas Transportation segment in 3Q2020 decreased by Ps. 2,073 million, compared to 3Q2019. The negative variation was due to the lack of tariff increase of the applicable tariffs (the last increase was on April 1, 2019) and the negative effect that the variation in the Consumer Price Index had on inflation-adjusted revenues.

Liquids revenues increased by Ps. 2,312 million in 3Q2020, mainly as a result of: (i) the

5

increase in the volume of ethane delivered compared to 3Q2019, after, as mentioned before, PBB was prevented to receive the normal supply of ethane, (ii) the higher volumes exported and (iii) the increase in the foreign exchange rate on sales denominated in US dollars. These were partially offset by the drop in prices.

Total volumes dispatched increased by 73%, or 150,396 short tons, resulting mainly from higher ethane volumes sold and propane and butane exported. The breakdown of volumes dispatched by market and product and revenues by market is included below:

The Other Services segment reported an increase of Ps. 101 million, mainly explained by higher natural gas transportation and conditioning services in Vaca Muerta and the increase in the foreign exchange rate on U.S. dollar-denominated revenues. These effects were partially offset by lower natural gas pipeline construction services provided through the TGS - SACDE joint venture and operation and maintenance services provided for natural gas pipelines and compression plants.

Cost of sales and administrative and commercialization expenses for 3Q2020 amounted to Ps. 7,431 million (compared to Ps. 8,084 million in 3Q2019), representing a decrease of Ps. 653 million. This variation is mainly due to the decline in: (i) repair and maintenance expenses of Property, Plant and Equipment, (ii) labor costs, (iii) turnover tax and export taxes and (iv) fees and services to third parties. These effects were partially offset by the increase in the costs of natural gas processed in the Cerri Complex, mainly due to the higher volumes of natural gas purchased.

The following table shows the main components of operating costs, administrative and commercialization expenses and their main variations for 3Q2020 and 3Q2019:

In 3Q2020, financial results were positive by Ps. 853 million compared to 2019. This positive variation is mainly due to the effect of the foreign exchange rate in 3Q2020. This effect was partially offset by the negative impact generated by financial assets and a lower positive effect on a net monetary position.

`10.```Outlook

The outbreak and spread of the virus called "Coronavirus" (or "Covid-19") has determined that the current global and macroeconomic context poses a scenario of important challenges in which we will have to develop our businesses. Given the magnitude of the spread of the virus, in March 2020, several governments around the world implemented drastic measures to contain the spread, including, among others, the closure of borders and the prohibition of travel to and from certain parts of the world for a period of time and finally the compulsory isolation of the population along with the cessation of non-essential commercial activities.

This brought about relevant consequences, including a significant economic contraction whose impact and scope are still unknown. Despite the fact that in several countries of the European continent, confinement measures are being taken again, initially for a one-month period, due to the sustained increase in contagions, the main focus of the pandemic is still located in the American continent, where the level of contagion continues elevated.

8

In Argentina, we are currently in a situation of social, preventive and compulsory isolation, established since March 20, 2020 by Presidential Decree No. 297/2020. Although with certain flexibilities, this measure is currently extended until November 8, 2020.

By this reason, at TGS we have complied with all the measures issued by the National Health Authority. Despite the isolation measures and the severe restrictions to movement, we maintain our operations because they are considered essential, preserving the health of all our collaborators. The impact of the COVID-19 brought about a greater deterioration in the main social and macroeconomic variables of Argentina, which led the National Government to adopt a series of measures to meet the needs of the most vulnerable sectors and those with the greatest impact.

The deterioration in the collections of the Natural Gas Transportation segment, the abrupt drop in the international prices of Liquids mentioned above, and the fragility of the energy sector in Argentina mean that we must adopt a series of measures aimed at generating efficient management of the resources.

Firstly, it is important to remember that at TGS we provide an essential service to the country that cannot be interrupted, whose equipment and facilities require the assistance of our maintenance teams, in compliance with protocols regarding transportation and works at the facilities. Even though during the winter demand grew and the transportation system became extremely rigid, we maintained the reliability of our system.

In this framework, we will be attentive to the talks with the national authorities in order to comply with the provisions of the Solidarity Law regarding the concretion of the new RTI process that allows us to receive tariff increases according to the quality of the service we provide. This will imply that we must develop a constructive dialogue with each of the valid interlocutors.

In the Liquids Production and Commercialization segment, the lack of agreement by the member countries of the Organization of Petroleum Exporting Countries ("OPEC") and the non-OPEC producers ("OPEC+") regarding the levels of oil production generated an unusual volatility and uncertainty in the energy market that together with the impact of COVID-19 caused an abrupt fall in the price of the Liquids that we commercialize and caused a framework of uncertainty in the energy development of Argentina as it was previously stated.

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

In the Other Services segment, we have to face an even more challenging framework, once the works for the collector natural gas pipeline and conditioning plant in Vaca Muerta are concluded, we will have to continue developing profitable businesses in a context that, as given, will not be favorable.

In financial terms, and given the aforementioned facts, we have made the necessary budgetary adjustments in order to preserve our financial position, make a prudent allocation of our resources, and mitigate the negative impact that the main macroeconomic variables have on our businesses and the delays in granting the tariff increases that affect our financial situation.

The impact of COVID-19 on financial markets has negatively affected the cost of loans, hedging activities and access to capital markets in general, which could limit our ability to obtain coverage or financing in a timely manner and in acceptable terms. Furthermore, the fragile economic environment in Argentina was intensified by the slowdown in economic activity caused by COVID-19 and other internal factors that may lead to an increase in the bad debt rates of our clients and their counterparts. Given our current lack of access to financial markets, we believe that we will have to rely solely on the cash flows generated by our operations to meet our working capital, debt service, and capital expenditures requirements for the foreseeable future.

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

9

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 29, 1992 and it is mainly engaged in the Transportation of Natural Gas, and Production and Commercialization of natural gas Liquids (“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 the 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’s controlling shareholder is Compañía de Inversiones de Energía S.A. (“CIESA”), which holds 51% of the common stock. Local and foreign investors hold the remaining ownership of TGS’s common stock. CIESA is under joint control and in equal parts of: (i) Pampa Energía S.A. (“Pampa Energía”) with 50%; (ii) Grupo Inversor Petroquímica S.L. (member of the GIP Group, led by the Sielecki family) and PCT L.L.C. with the remaining 50%.

The following table shows the organizational structure, shareholders and related parties of TGS as of September 30, 2020:

Economic context and Impact of COVID-19 (“COVID”) on TGS operations

The Company operates in an economic context whose main variables have recently had a strong volatility as a consequence of political and economic events both domestically and internationally.

As of 2020, the spread of COVID has impacted a large number of countries with a significant level of severity. In March 2020, the World Health Organization (WHO) declared Covid-19 a global pandemic. During this period, countries, organizations, and TGS have taken considerable steps to mitigate the risk to communities, employees, and business operations.

_____________________________________________________________________________________________________

During this period, the countries implemented a series of drastic measures including, among others, closing borders and mandatory isolation of the population, paralyzing non-essential economic activity and causing a marked global economic recession. This resulted in similar measures being adopted by organizations and TGS to mitigate risk to communities, employees and business operations.

While, between the months of May and August 2020, a gradual process of deconfinement developed in the European continent, as in several countries in Asia and Oceania, the main focus of the pandemic was located in the American continent, where the level of contagions grew steadily. However, since mid-September, the numbers of contagions have increased in the European continent, leading countries to restart with certain measures that imply a retraction of the economy and an increase in volatility as a result of the uncertainty regarding the health situation. Meanwhile, the American continent has maintained a high level of contagions.

In particular, the Argentine Government implemented a series of measures aimed at reducing the circulation of the population, providing for preventive and compulsory social isolation since March 20, 2020, allowing circulation only of those people linked to the provision / production of essential services and products. This isolation will be extendable for the time considered necessary in light of the epidemiological situation. Currently, by means of Presidential Decree No. 814/2020 it is extended until November 8, 2020.

The Argentine economy was in a recessive process and the emergence of the pandemic in March 2020 made this scenario even more complex. In this sense, and as in other countries, the Argentine government has implemented a series of economic measures in order to mitigate the impact on the most vulnerable sectors and to sustain the economy.

The Company's Management has implemented measures with the objective of ensuring the health of its employees, maintaining the continuity of its operations, and preserving its financial situation.

The main macroeconomic issues of our country are:

`·```The Emerging Markets Bonds Index or EMBI as of September 30, 2020 amounted to 1,300 points.

`·```Accumulated inflation between January 1, 2020 and September 30, 2020 reached 22.3% (Consumer Price Index - “CPI”).

`·```Between January 1 and September 30, 2020, the Argentine Peso depreciated 27% against the US dollar, according to the exchange rate of the Banco de la Nación Argentina (“BNA”). Likewise, as of September 30, 2020, the gap with respect to the alternative prices of the US dollar that are obtained in the market was close to approximately 91%.

`·```The Central Bank of the Argentine Republic (“BCRA” for its acronym in Spanish) tightened exchange restrictions (for more information see “Note 5 - Financial Risk Management”), which also affect the value of foreign currency in existing alternative markets.

Although the activities carried out by the Company are considered essential, the situations described above have had an impact on the different business segments in which it operates.

In the Natural Gas Transportation segment, the Argentine Government through Presidential Decree No. 311/2020 (the "Decree 311") provided for the suspension of public service outages for lack of payment for a period of 180 days, subsequently extended for a similar period, and the implementation of various measures aimed at sustaining the income of those sectors of the economy that suffer the greatest impact. Both the above mentioned and the isolation measures have involved certain delays in the receipt of collections related to this business segment which, although it has improved recently, cannot ensure that this situation is maintained over time.

In the Liquids Production and Commercialization segment, during the first nine months of 2020, and particularly during the third quarter of the year, the international reference prices of the liquids produced and commercialized by the Company were impacted after, added to the negative impact of the development of the COVID on the world-wide supply and demand of products, the member countries of the Organization of the Petroleum Exporting Countries ("OPEC") and the non-OPEC producers ("OPEC+") have not reached an agreement on oil production levels, all of which has generated a scenario of high volatility. Also, in the domestic market, the price of natural gas at wellheads during the third quarter was approximately 40% lower than the same period in 2019. As for natural gas production, in the same period, production recorded a 11% year-on-year fall, due to the effects limitations of preventive and mandatory social isolation on activity, combined with a higher autumn temperature. In this context, the National Government is evaluating the implementation of a new program to promote natural gas production and sustain the industry.

As for the Other Services segment, in the third quarter of 2020 the production and price of natural gas at wellheads in the Neuquina basin maintained the trend described at the national level. This decrease, added to the macroeconomic situation in Argentina, continue to generate uncertainty regarding the development of natural gas in the Vaca Muerta area.

At the date of issuance of these Condensed Interim Consolidated Financial Statements, it is not possible to foresee the impact or the duration of said situation of volatility and uncertainty, nor the effect that the measures adopted and those that may be adopted in the future may have, but they could negatively affect the results, financial situation and cash flows. However, given the Company's financial situation, the above-mentioned events are not currently expected to affect the continuity of the business, and it is therefore estimated that the Company will be able to continue to meet its financial commitments in the near future.

In this regard, the Company evaluated that as of September 30, 2020, there were no indicators of impairment in addition to those identified at March 31, 2020 in accordance with IAS 36, date at which the impairment tests have been performed on the assets included within Property, Plant and Equipment (“PPE”). The disclosures relating to the test performed and its result are included in Note 6 to these Consolidated Condensed Interim Financial Statements.

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.

`3.```BASIS OF PRESENTATION

The CNV, in Title IV, Chapter III, Article 1 of the Rules has provided that listed companies must submit their condensed consolidated financial statements by applying Technical Resolution No. 26 (modified by Technical Resolution No. 29) of the Argentine Federation of Professional Councils of Economic Sciences ("FACPCE"), which adopts the International Financial Reporting Standards ("IFRS") issued by the IASB, its amendments and circulars for the adoption of IFRS that the FACPCE dictates in accordance with the provisions of that Technical Resolution.

New accounting standards, modifications and interpretations issued by the IASB that have been adopted by the Company

The Company has applied the following regulations and / or modifications for the first time as of January 1, 2020:

Definition of materiality (amendments to IAS 1 and IAS 8)

In October 2018, the IASB included certain modifications to IAS 1 "Presentation of financial statements" and IAS 8 "Accounting policies, changes in accounting estimates and errors" with the aim of clarifying the concept of materiality and aligning this definition to the modifications introduced in the Conceptual Framework.

`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, that were described in the annual financial statements as of December 31, 2019.

In this sense, the Company operates in an economic context whose main variables have recently had a strong volatility as a consequence of public and economic events in the national and international scope mentioned in Note 1.

As mentioned in Note 1, the main variables of the worldwide and Argentinean economies have also negatively affected the cost of loans, hedging activities, liquidity and access to capital in general. In the local market, particularly, the shares of the main listed companies, sovereign bonds and the Argentine peso experienced a sharp drop in their market value.

In addition, as from April 2020, by issuing Communication "A" 7001, subsequently amended by Communication "A" 7030, 7042, 7052 and 7068, the BCRA established measures that intensify restrictions on the access to the official foreign exchange market (“MULC”) including measures related to the operation of public trade assets by the companies.

Additionally, on May 25, 2020, and June 19, 2020, the CNV issued General Resolutions No. 841 and 843, establishing restrictions for the purchase and sale of negotiable securities in U.S. dollars, or their transfer to depositary companies abroad. Subsequently, by means of General Resolution N° 862, the CNV ordered certain flexibilities to the terms of permanence of said securities.

These measures aimed at restricting the MULC in order to contain the demand for dollars imply a request for prior authorization from the BCRA for certain transactions, including the following:

`·`Payment of dividends to non-residents;

`·`Payment of imports of certain goods abroad or cancellation of debts originated in their importation, except for some exceptions expressly provided for in the applicable regulations;

`·`The creation of external assets; and

`·`The payment of financial loans to non-residents.

If access to the MULC has been requested, the commitment must be assumed to enter and settle in the exchange market, within five business days of their availability, those funds received abroad originating from the collection of loans granted to third parties, the collection of a term deposit or the sale of any type of asset, when the asset had been acquired, the deposit constituted or the loan granted after May 28, 2020.

Additionally, on September 15, 2020, the BCRA published Communications "A" 7105 and 7106, which establishes, among other measures, that those who register loans with independent parties with capital maturities in foreign currency scheduled between October 15, 2020 and March 31, 2021, must submit to the BCRA a refinancing plan for capital maturities based on the following criteria: (a) that the net amount for which the foreign exchange market will be accessed original terms will not exceed 40% of the principal amount due in the period indicated above, and (b) that the rest of the capital is, at least, refinanced with a new external debt with an average life of 2 years, provided that the new debt is settled in the exchange market.

The aforementioned rule does not have immediate effect on the Company since the amortization of the capital of its notes operates on May 2, 2025, not within the aforementioned period. On the other hand, as of the date of issuance of these interim

condensed consolidated financial statements, the Company paid the total interest installment corresponding to its financial debt on November 2, 2020.

Additionally, the exchange regime already determined as mandatory the settlement in national currency of the funds obtained as a result of the following operations and concepts, among others:

`·`Exports of goods and services;

`·`Collections of pre-financing, advances and post-financing of goods export;

`·`Exports of services;

`·`Disposal of external assets.

These exchange restrictions, or those that may be provided in the future, could affect the Company's ability to access the official exchange market to acquire the necessary foreign exchange to meet its financial obligations. Assets and liabilities in foreign currency as of September 30, 2020 have been valued considering the current prices in the MULC. After September 30, 2020, the Company incurred Ps. 1,861,954 in foreign exchange losses on financial instruments maintained at the end of the period.

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 considers that its current financial situation will allow it to comply, in the short term, with its commitments in foreign currency. The Company's financial statements should be read under the light of these circumstances.

`6.```CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS

The preparation of the condensed interim consolidated financial statements in accordance with generally accepted accounting principles requires management to make accounting estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting period. These estimates require management to make difficult, subjective or complex judgments and estimates about matters that are inherently uncertain. Management bases its estimates on various factors, including past trends, expectation of future events regarding the outcome of events and results and other assumptions that it believes are reasonable.

As mentioned in Note 1, as a consequence of the development of COVID, the main macroeconomic and business variables of Argentina suffered a significant deterioration, which meant that the Argentine government must take a series of measures aimed at containing the negative impact. Therefore, given that it is an indicator of impairment of the amounts of Property, Plant and Equipment (“PPE”), as of March 31, 2020, the cash flows used to determine the recoverable value were re-estimated for each of the Cash Generating Units (“CGU”) defined by the Company.

The value in use of PPE is sensitive to the significant variation in the assumptions applied, including the determination of future tariffs determined by the Argentine Government in the Natural Gas Transportation segment, and the expectation of business development in the Vaca Muerta area in the Other services segment.

In the Natural Gas Transportation segment, the Company considered a less favorable scenario taking into account the current regulatory framework and the measures taken by the Argentine Government after December 31, 2019. This implies that the current tariff would not be adjusted accordingly with future inflation during 2020.

AS OF SEPTEMBER 30, 2020 AND COMPARATIVE INFORMATION

(Stated in thousands of pesos as described in Note 3, unless otherwise stated)

_____________________________________________________________________________________________________

In the Liquid Production and Commercialization segment, TGS has considered the current drop in future international liquids prices based on publicly available information.

The estimated recoverable values of PPE items are sensitive to significant variation in the assumptions made. In any case, it is not possible to ensure with certainty that the actual cash flows will be in line with the assumptions applied. Therefore, significant differences may arise in the future in relation to the estimated values in use.

The Company also updated its assessment of impairment indicators in accordance with IAS 36 as of September 30, 2020. The conclusion of that assessment was that no new factors were identified that would adversely affect the assumptions underlying the recoverable value of the assets included in PPE, with respect to the last assessment made, as of March 31, 2020.

According to the analysis mentioned above, the Company did not identify the need to book any impairment of the PPE amounts as of September 30, 2020.

`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, 2020 and 2019 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 8 “Operating Segments” 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) Other Services including midstream, among others, and (iv) Telecommunications. These last three business segments are not regulated by ENARGAS. Production and Commercialization of Liquids segment is regulated by the SE.

`1.2` Fair value measurement hierarchy and estimates

According to IFRS 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). Within this level, the Company includes those derivate financial instruments for which it was not able to find an active market.

`·`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, 2020:

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.

As of September 30, 2020, the carrying amount of certain financial instruments used by the Company including cash, cash equivalents, other investments, receivables, payables and short-term loans are representative of fair value because of the short-term nature of these instruments.

The estimated fair value of Non-current loans is estimated based on quoted market prices. The following table reflects the carrying amount and estimated fair value of the 2018 Notes at September 30, 2020, based on their quoted market price:

19. REGULATORY FRAMEWORK

The main regulatory issues are described in Note 17 to the annual consolidated financial statements. The developments for the nine-month period ending 30 September 2020 are described below:

Regulatory framework for the Natural Gas Transportation segment

On June 9, 2020, through Resolution No. 80/2020, ENARGAS created the Coordination and Centralization Commission - Law No. 27,541 and Presidential Decree No. 278/20, which will have the purpose of coordinating the process of integral tariff review provided for in Article 5 of Law No. 27. 541 - Law of Social Solidarity and Production Reactivation within the Framework of the Public Emergency ("Solidarity Law") which, additionally, provided that natural gas transportation and distribution tariffs would remain unadjusted for a maximum period of 180 days as of December 23, 2019 and empowered the Executive Branch to renegotiate them, either within the framework of the RTI in force or by means of an extraordinary review as provided for in the Natural Gas Law.

On June 19, 2020, the Executive Branch issued Presidential Decree No. 543/2020 extending the validity of the aforementioned Article 5 for an additional period of 180 calendar days, until December 16, 2020.

Regulatory framework of the Production and Commercialization of Liquids segment

Domestic market

In accordance with Presidential Decree No. 311 dated March 25, 2020, the maximum reference prices for the commercialization of liquefied petroleum gas (LPG), which the Company commercializes in the domestic market, remain unchanged for a period of 180 calendar days from its issuance.

Foreign market

Presidential Decree No. 488/2020 regulated the applicable tax rate on exports of certain oil and gas products, including those products that we export, establishing a range between 0% and 8% depending on the "ICE Brent first line" barrel price. If the mentioned price is below US$ 45 the rate will be zero. On the other hand, if the price is equal to or higher than US$ 60, an 8% rate will be paid, which will be variable if the price is between US$ 45 and US$ 60.

I. Report on the Financial Statements

Introduction

1. We have reviewed the accompanying condensed interim consolidated financial statements of Transportadora de Gas del Sur S.A., which comprises: (a) the consolidated statement of financial position at September 30, 2020, (b) the consolidated statements of comprehensive income, changes in equity and cash flows for the three and nine-month period then ended, and (c) a summary of significant accounting policies and other explanatory notes.

2. The balances and other information corresponding to the fiscal year 2019 and to its interim periods are an integral part of the financial statements mentioned above; therefore, they must be considered in connection with these financial statements.

The Company’s Board of Directors is responsible for the preparation and presentation of these condensed interim consolidated financial statements under the International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”), and adopted by the Federación Argentina de Consejos Profesionales de Ciencias Económicas (“FACPCE”) as its professional accounting standards and added by the Comisión Nacional de Valores (“CNV”) to its regulations; therefore, it is responsible for the preparation and presentation of the condensed interim consolidated financial statements mentioned above in accordance with International Accounting Standard 34 “Interim Financial Reporting” (“IAS 34”). The Company’s Board of Directors is also responsible for performing the internal control procedures that they may deem necessary to enable the preparation of the condensed interim consolidated financial statements that are free from material misstatements, either due to errors or irregularities.

Scope of review

4. Our responsibility is to express a conclusion on the accompanying consolidated financial statements based on our review, which was conducted in accordance with International Standard on Review Engagements 2410, 'Review of interim financial information performed by the independent auditor of the entity', as issued by the International Auditing and Assurance Standards Board (“IAASB”), and adopted by the FACPCE as its standard of review in Argentina by Technical Resolution N° 33. Such standard requires auditor to comply with the ethical requirements relevant to the audit of the Company’s annual financial statements.

A review is substantially less in scope than an audit conducted in accordance with International Standards
