REVIEW REPORT ON THE CONSOLIDATED CONDENSED INTERIM FINANCIAL STATEMENTS

To the President and Directors of

Pampa Energía S.A.

Legal address: Maipú, 1

Autonomous City of Buenos Aires

Tax Code No.: 30-52655265-9

Introduction

We have reviewed the accompanying consolidated condensed interim financial statements of Pampa Energía S.A. (hereinafter called 'the Company') and its subsidiaries, including the consolidated condensed interim statement of financial position at June 30, 2021, the consolidated condensed interim statement of comprehensive income for the six and three-month periods ended June 30, 2021, the consolidated condensed interim statements of changes in equity and of cash flows for the six-month period then ended, and the selected explanatory notes.

The balances and other information for the fiscal year 2020 and its interim periods is an integral part of the Financial Statements mentioned above; therefore, they must be considered in connection with those Financial Statements.

Board's responsibility

The Board of Directors of the Company is responsible for the preparation and presentation of the financial statements in accordance with International Financial Reporting Standards, adopted by the Argentine Federation of Professional Councils in Economic Sciences (FACPCE, for its acronym in Spanish) as professional accounting standards and included by the National Securities Commission (CNV, for its acronym in Spanish) in its regulations, as approved by the International Accounting Standards Board (IASB), and is therefore responsible for the preparation and presentation of the consolidated condensed interim financial statements mentioned in the first paragraph, in accordance with International Accounting Standard 34 'Interim Financial Information' (IAS 34).

Scope of our review

Our review was limited to the application of the procedures established under International Standards on Review Engagements ISRE 2410 Review of Interim Financial Information Performed by the Independent Auditor of the Entity, adopted as a review standard in Argentina by Technical Pronouncement No. 33 of the FACPCE and approved by the International Auditing and Assurance Standards Board (IAASB). A review of interim financial information consists of inquiries of Company staff responsible for preparing the information included in the consolidated condensed interim Financial Statements and of analytical and other review procedures. This review is substantially less in scope than an audit examination conducted in accordance with international standards on auditing and consequently it does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion on the financial position, the consolidated comprehensive income, or the consolidated cash flows of the Company.

NOTES TO THE UNAUDITED CONSOLIDATED CONDENSED INTERIM
FINANCIAL STATEMENTS

For the six-month period ended June 30, 2021

presented in comparative format

(In millions of Argentine Pesos ('$'))

NOTE 1: GENERAL INFORMATION

1.1General information of the Company

The Company is a fully integrated power company in Argentina which directly and through its subsidiaries, participates in the electric energy and gas value chains.

In the generation segment, the Company, directly and through its subsidiaries and joint ventures, has a 4,955 MW installed capacity, which represents approximately 12% of Argentina's installed capacity, being one of the fourth largest independent generator in the country.

In the oil and gas segment, the Company is one of the leading oil and natural gas producers in Argentina, with operations in 13 production areas and 5 exploratory areas and a production level of 7.0 million m3/day of natural gas and 4.4 thousand barrels of oil equivalent per day for oil during the six-month period ended June 30, 2021. Its main natural gas production blocks are located in the Provinces of Neuquén and Río Negro.

NOTE 1: (Continuation)

1.2Economic context in which the Company operates

The Company operates in a complex economic context, which volatility was deepened by the outbreak of the COVID-19 locally and internationally.

In 2021, as a result of the new increase in infection levels, the governments of different countries in the world, including the Argentine Government, temporarily reimplemented some measures, such as restrictions on movement of the population.

As regards measures directly affecting the generation sector's economic and financial situation, it is worth highlighting that SE Resolution No. 440/21, passed in the second quarter, provided for a 29% increase in spot remuneration values (see Note 2.1 for details), which update had been suspended as from March 2020.

Besides, during the second quarter certain social conflicts and wage protest demonstrations mostly during the month of April, prevented the freedom of movement on routes in the Province of Neuquén during the month of April 2021and, even though no significant impact has been verified on the production by the Company's assets in this basin during the protest roadblocks, they have affected the ordinary execution of the works committed by the Company under the GasAr Plan, and hindering the timely and proper compliance with the agreed investment plan necessary to achieve committed gas production. The Company has sent the respective Force Majeure communications to the SE, CAMMESA and the Gas Distribution Companies with which it has executed gas supply agreements for the volumes awarded under the GasAr Plan.

It is impossible to foresee how measures will continue evolving and their impact on the economy in general and the Company in particular, or to which extent the Company's business and the results of its operations will be affected in the future.

The Company's Management permanently monitors the evolution of the variables affecting its business to define its course of action and identify potential impacts on its assets and financial position.

The Company's Consolidated Condensed Interim Financial Statements should be read in the light of these circumstances.

NOTE 2: REGULATORY FRAMEWORK

2.1 Generation
2.1.1 Fuel supply for thermal power plants

As from the application of the GasAr Plan, an operating assignment scheme was established for firm transportation and gas contracts entered into by generators. Under this assignment, agents should waive all claims regarding the application of SE Resolution No. 354/20, which established a new dispatch order for generation units based on the fuel supplied for their operation in accordance with a centralized dispatch scheme. The Company executed this assignment with CAMMESA, setting certain guidelines for the calculation of fuel costs to support their Energía Plus contracts.

2.1.2 Seasonal Programming

SE Resolution No. 24/21, published in the BO on January 15, 2021, approved the seasonal programming for the November 2020-April 2021 period. Seasonal prices remained unchanged until the month of April 2021, with reference prices being those in effect since 2019. In turn, the stabilized price set by SSEE Provision No. 75/18 for transmission in the extra high voltage system and the distributor-based main distribution price have remained unchanged.

As from April 2021, pursuant to SE Resolution No. 131/21 (amended by SE Resolutions No. 154/21 and 204/21), the reference price for power for the Distributor's Large Users peak demand increases by 89% (except for public health and education organizations and agencies), reducing the gap with the actual cost and, consequently, subsidies. The remaining prices for electricity applicable to the end demand have not been modified.

On May 11, 2021, SE Resolution No. 408/21 was published, which approved the final winter seasonal reprogramming for the May 2021 - November 2021 period, keeping unchanged the reference prices current as of April 30, 2021, and the stabilized price for the high-voltage and main distribution electricity transmission service established by SSEE Provision No. 75/18.

2.1.3 Remuneration scheme for the spot market

On May 19, 2021, SE Resolution No. 440/21 provided for a 29% increase in spot generation remuneration values, and repealed the automatic adjustment mechanism established by SE Resolution No. 31/20. This increase will be applicable as from the economic transaction for February 2021, provided the generator waives/dismisses all administrative/judicial claims filed on account of the failure to apply the automatic adjustment formula provided for by SE Resolution No. 31/20 within 30 days as from its publication. If such requirement is not met within this term, the remuneration adjustment will be applicable as from the month in which the generator submits its waiver/dismissal, and the remuneration established by SE Resolution No. 31/20 for that generator will be applicable until then. The waiver includes the obligation to withdraw any claim brought by the generating agent's shareholders on account of the failure to apply the automatic adjustment mechanism provided for by SE Resolution No. 31/20, whether in Argentina or abroad.

The Company and its subsidiaries filed the waiver/dismissal within the previously indicated 30-day period. The impact of the application of this resolution in the months of February and March generated a $ 555.6 million increase in revenue from sales as of June 30, 2021.

NOTE 2: (Continuation)

2.1.4 Restructuring of Federal Government's assets in the energy sector

The Federal Government has modified the policy adopted by the previous administration regarding the restructuring of assets in the energy sector, and has abrogated DNU No. 882/17, which provided for the sale of CTEB, CT Brigadier López, CT Manuel Belgrano II, IEASA's stake in CITELEC, the Federal Government's stake in Central Dique; CTG, Central Puerto, CT Patagónicas, TRANSPA, Dioxitek, and the Federal Government's rights in TMB, TSM, Termoeléctrica Vuelta de Obligado and Termoeléctrica Guillermo Brown. In the opinion of the Company's Management, this abrogation would not affect the rights acquired by the Company under CTEB's goodwill transfer process.

Additionally, it provided for the transfer to IEASA of TMB and TSM's shares held by the Federal Government. Earnings received by IEASA must be invested in energy infrastructure projects.

Finally, it granted to IEASA the exploratory permits for the MLO_115 and MLO_116 offshore areas and provided for the issuance of National Treasury guarantees as collateral for the contract for the acquisition of natural gas entered into with Bolivia.

2.1.5 MATER dispatch priority

SE Resolution No. 551/21 published on June 16, 2021 modified the dispatch priority maintenance system established by Resolution No. 281/17. Overall, it replaces the granting of a security for the maintenance of the dispatch priority by the payment of a quarterly installment of US$ 500/MW until commissioning within the declared term or a maximum term of 24 months as from the priority assignment.

Additionally, it allows projects with an assigned dispatch priority but not yet commissioned to continue their execution keeping the dispatch priority, or such priority may be waived, thus releasing the transmission capacity.

The Company, as owner of the PEPE IV Wind Farm project, located in Las Armas, Province of Buenos Aires, notified its decision to waive the timely granted dispatch priority, and recovered the security it had provided. As a result, CAMMESA notified that the already initiated execution of the security was determined to be moot as it had no further claim against the Company; therefore, as of June 30, 2021, the amount of US$ 12.5 million provided for to such effect was recovered and recognized in earnings, under the item 'Other operating income' of the Consolidated Condensed Interim Statement of Comprehensive Income.

2.2 Natural Gas Market
2.2.1 Argentine Natural Gas Production Promotion Plan ('GasAr Plan')

On March 9, 2021 Resolution No. 169/21 was published in the BO, which awarded natural gas volumes offered under the GasAr Plan, Round II Tender. In this sense, the Company was awarded a volume of 0.70 million m3/day, 0.90 million m3/day and 1 million m3/day for the months of June, July and August-September 2021, respectively, and 0.86 million m3/day to meet the winter peak demand for the years 2022 through 2024, at a price of US$ 4.68 MMbtu.

With this tender, Pampa's injection commitment increases to 9 million m3 per day for the 2021-2024 winter periods which, compared to 2020, represents a 15% year-on-year production increase and a 28% increase in the winter period, the months with the largest gas supply needs in the country.

2.2.2 Natural Gas Export Procedure

On April 27, 2021, pursuant to SE Resolution No. 360/21, a new procedure was regulated for the authorization of natural gas exports that contemplates the firm condition and the preferential order for GasAr Plan's awardees and abrogates the previous procedure established by SGE Resolution No. 417/19 and SHC Provision No. 284/19. Furthermore, prior to the granting of each permit, the enforcement authority will perform a comprehensive and systemic analysis safeguarding the supply to the Argentine domestic market since, once authorized on a firm basis, it may not be further reviewed.

2.3 Gas transportation

TGS's tariff situation

The public hearing called by ENARGAS to discuss the RTT pursuant to the provisions of Executive Order No. 1,020/20 took place on March 16, 2021. In this respect, TGS, without waiving the whole of its percentage share, alternatively submitted in the hearing its tariff increase proposal, assessed at 58.6% as from April 1, 2021. This increase was assessed based on the financial needs to meet operating and financial costs, capital expenditures and taxes, which were calculated taking into consideration the evolution of the inflation rate over a 12-month period as from its beginning. The requested increase only contemplates the funds necessary to meet its obligations as licensee.

Additionally, TGS denied and dismissed the arguments raised in the public hearing, which considered that the current natural gas transportation tariff is not fair or reasonable given the alleged existence of serious flaws in the administrative acts resulting from the proceedings for the last Comprehensive Tariff Regime established for TGS.

On April 28, 2021, ENARGAS submitted to TGS the 2021 Transitional Agreement pursuant to Executive Order No. 1,020/20, which: (i) does not grant a transitory tariff update, keeping unchanged the tariff schemes approved by ENARGAS in April 2019; (ii) provides that, as from May 2021 and until the Final Renegotiation Agreement enters into effect, ENARGAS will recalculate the transportation tariffs effective at the time, with validity as from April 1, 2022.; (iii) does not establish a mandatory investment plan; and (iv) establishes the prohibition to distribute dividends, early cancel financial and commercial debts taken on with shareholders, acquire other companies, or grant loans.

NOTE 2: (Continuation)

On April 30, 2021 and through a note sent to this body, TGS expressed that, given the context in which it develops its activities and the proposed terms and conditions, it is not feasible for TGS to enter into the 2021 Transitional Agreement Project.

Later, on June 2, 2021, ENARGAS issued Resolution No. 149/21 approving an RTT for TGS effective as from that date and under the same terms of the project timely submitted on April 28, 2021.

In July 2021, TGS filed motions for reconsideration, subsidiarity filing a hierarchical appeal, before the PEN, the National Ministry of Economy and ENARGAS according to the respective jurisdictions of each of these bodies in the passing of the regulations associated with Resolution No. 149/21, requesting the declaration of nullity of the RTT and the reinstatement of the RTI.

The challenges are based on: (i) the illegality of Executive Order No. 1,020/20, as it does not observe the delegation lines provided for by Act No. 27,541 and, as a DNU, does not meet the requirements established by the National Constitution; (ii) the extension of the emergency period beyond that established by the Congress; (iii) the fact that the renegotiation is not made pursuant to Act No. 24,076; (iv) the disregard for the principle of fair and reasonable tariffs, and the rights acquired by TGS under the License, the Contractual Adjustment Memorandum of Understanding and the RTI; and (v) the suspension of the RTI for reasons of public interest, which merits the recognition of the compensations provided for by both the Administrative Procedures Act and the License Basic Rules.

In turn, the restrictions on the management and administration of TGS have been challenged for lacking legal justification, as the emergency declared by Act No. 27,541 only empowered the PEN to renegotiate the RTI, but not the License. The challenges and the motion for reinstatement of the RTI have been filed notwithstanding TGS's right to the payment of the compensations it is entitled to on account of the breach of the RTI as from April 2019.

As of the date of issuance of these Consolidated Condensed Interim Financial Statements, TGS has not received an answer to the filed motions, and is evaluating other measures to take to continue safeguarding its rights and thus attain a fair and reasonable tariff for the natural gas transportation segment.

2.4 Transmission

Transener and Transba's tariff situation

On January 19, 2021, pursuant to Resolution No. 17/21 the ENRE launched the proceeding for the transitory adjustment of tariffs of the transmission public utility aiming to establish a RTT until reaching a Final Renegotiation Agreement, and summoning Transportation Companies. In this sense, a request for the information necessary to begin this process was received, and Transener has complied with this requirement, prioritizing the operating costs and capital expenditures required to maintain service quality.

On March 3, 2021, pursuant to Resolutions No. 54/21 and 55/21, the ENRE convened a Public Hearing for March 29, 2021 to provide information and gather feedback on the RTT for Transener and Transba, respectively, within the RTI Process and prior to the definition of tariffs.

On April 14, 2021 the Public Hearing Closing Report was published in the BO. As of the date of issuance of these Consolidated Condensed Interim Financial Statements, the negotiations with the ENRE to reach a Renegotiation Transitional Agreement for the RTI continue under way.

Besides, on July 3, 2018 the ENRE informed of the launching of the proceeding for the determination of the remuneration to Independent Transmission Companies in the exploitation stage: TIBA (Transba), the Fourth Line (Transener), YACYLEC and LITSA. In this respect, on October 8, 2018, information on costs, investments and tariff claims corresponding to the Fourth Line and TIBA were submitted to the ENRE. As of the date of issuance of these Consolidated Condensed Interim Financial Statements., the ENRE has not issued a resolution with the results of the analysis of the requested information.

2.5 Regulations on access to the MLC

The main regulations on MLC inflows and outflows issued by the BCRA in the six-month period ended June 30, 2021 are summarized below:

The need for BCRA's prior authorization to access the MLC is extended until December 31, 2021 inclusive in the following cases: (i) the cancellation of principal of foreign financial debts with foreign affiliates, and (ii) payments for the import of goods or the cancellation of principal of debts arising from the import of goods.

The BCRA extended the obligation to submit a refinancing plan for certain debts and principal maturities scheduled until December 31, 2021, maintaining the following criteria: (i) access to the MLC for up to 40% of the principal amount, within the original term; and (ii) the refinancing of the principal balance, through new foreign indebtedness with an average life of 2 years. Debts with principal maturities for amounts up to US$ 2,000,000 are exempted from the obligation to submit such indebtedness plan, and will have access to the MLC.

NOTE 2: (Continuation)

BCRA Communication 'A' 7196 established, among other modifications, a series of measures aiming to make regulations more flexible so as to facilitate the exchange or financing of private-sector liabilities abroad that have been entered and settled through the MLC and concerted as from January 7, 2021, such as: (i) the extension of the term before the maturity date to access the MLC for the cancellation of principal and interest of foreign financial debts or debt securities publicly registered in the country and denominated in foreign currency; and (ii) the possibility to accumulate funds originating from the collection of goods and services exports in foreign and/or domestic accounts destined to guarantee the payment of maturities of debts concerted as from January 2021, among others. Furthermore, the BCRA created a Registry of Foreign Exchange Information of Exporters and Importers of Goods as a requirement to access the MLC as from May 1, 2021 for forex outflow transactions, including swaps and arbitrations. This requirement will not apply in case of access to the MLC for the cancellation of financing denominated in foreign currency granted by local financial entities. Obliged subjects should enroll in this registry by March 31 each year and report any change in the recorded information within 15 business days of its occurrence. The Company has been declared an obliged subject by the BCRA, and has already enrolled in this registry.

On April 8, 2021, the BCRA regulated the Investment Promotion Regime for Exports created by DNU No. 234/21 which, among other issues, establishes the possibility to apply foreign exchange collections to projects under such regime for certain transactions, as long as the requirements set forth by the provision are met.

Additionally, on July 10, 2021 the BCRA, pursuant to Communication 'A' 7327, adopted new restrictions to access the MLC, including the following additional requirements effective as from July 12, 2021: (i) the filing of a new affidavit stating that no exchange of securities for other foreign assets has been made within 90 calendar days prior to the access to the MLC, and the commitment not to make them within 90 calendar days after such access; and (ii) if the customer is a legal entity, the filing of an additional affidavit stating: (a) details of the individuals or legal entities exercising a direct control relationship over the customer, according to BCRA's regulations on Large Exposures to Credit Risk; and (b) that on the day that access to the MLC is requested and in the previous 90 calendar days, no local-currency funds or other liquid domestic assets have been delivered to any individual or legal entity exercising a direct control relationship over it, except for those directly associated with regular transactions for the acquisition of goods and/or services. The requirement stated in item (ii) (b) will be deemed duly met if the customer submits an affidavit regarding transactions with securities of each of these individuals or legal entities pursuant to the current exchange regulations in force.

2.6 Tax regulations

2.6.1 Income tax rate

On June 16, 2021, Act No. 27,630 was published in the BO, which modified the income tax rate effective for fiscal years starting as from January 1, 2021 inclusive. This modification provides for the application of a tiered rate scheme and, if applicable, a fixed tax according to the accumulated net taxable income tier: (i) for accumulated net income of up to $ 5 million, it establishes a 25% rate; (ii) for accumulated net income between $ 5 and $ 50 million, it establishes a fixed tax of $1.25 million plus a 30% rate over the surplus of $ 5 million; and (iii) for accumulated net income above $ 50 million, it establishes a fixed tax of $ 14.75 million plus a 35% rate over the surplus of $50 million. The accumulated net income amount will be adjusted yearly, as from January 1, 2022, taking into consideration the annual CPI variation published by the INDEC.

The impacts of this change on the current and deferred tax have been recorded in these Consolidated Condensed Interim Financial Statements considering the effective rate expected to be applicable on the probable date of reversal of such deferred assets and liabilities.

2.6.2 Dividend tax

Pursuant to the provisions of Act No. 27,430, dividends from earnings accrued during fiscal years beginning as from January 1, 2020 would be subject to a 13% withholding. However, after the modifications introduced by Acts No. 27,541 and 27,630, the 7% withholding rate remains in effect as from December 31, 2019, with no modifications for future fiscal years.

5.1 Sale of controlling stake in Edenor

On June 24, 2021, ENRE Resolution No. 207/21 was published in the BO, which authorized the Company to transfer all Class A common shares, representing 51% of the capital stock and votes of Edenor, to Cono Sur S.A.

5.2.3 Investment in CTB

Financial Trust Agreement

On April 13, 2021, the ninth amendment to the Enarsa-Barragán Trust Agreement was entered into among CTB, in its capacity as trustor, BICE Fideicomisos S.A., in its capacity as trustee, and CAMMESA, in its capacity as assigned debtor, in order to include the new payment schedule effective as from the partial early redemption of the VRDs issued under the Enarsa-Barragán Financial Trust for a total amount of US$ 130 million executed on October 16, 2020.

As of the date of issuance of these Consolidated Condensed Interim Financial Statements, the total outstanding VRDs (amortization installments plus deferred interest, pursuant to the definition of these terms in the Trust Agreement) amount to US$ 93.7 million.

Issuance of Corporate Bonds

On June 4, 2021, CTB issued: (i) Class 1 Corporate Bonds for a total amount of US$ 27.3 million, accruing interest at an annual fixed rate of 4% and maturing on June 4, 2023; and (ii) Class 2 Corporate Bonds for a total amount of 37,504,954 units of purchasing power ('UVAs'), adjustable by the Reference Stabilization Coefficient (CER), equivalent to $2,928 million, accruing interest at a fixed 4% rate and maturing on June 4, 2024. Class 1 and Class 2 Corporate Bonds are secured by a personal guarantee subject to a condition precedent and subsequent granted by YPF and Pampa.

As of the date of issuance of these Consolidated Condensed Interim Financial Statements, CTB is in compliance with all the covenants under the CBs, which are the customary ones for this kind of issuances.

NOTA 5: (Continuación)

Syndicated loan

As of June 30, 2021, CTB repaid at maturity the first installment of the syndicated loan in the amount of US$ 29.2 million. As of the date hereof, CTB has paid an additional amount of US$ 4 million.

Closing to combined cycle project

CTB is moving forward with the execution of the works associated with the closing to combined cycle commitment to increase the installed capacity from 567 MW to 847 MW, with a total investment estimated at US$ 212 million.

It is worth highlighting that the Argentine Government's measures to contain the spread of COVID-19 have affected the works execution progress, delaying the originally planned term for commissioning and generating several instances of review in the schedule and the scope of the tasks necessary to complete the works, with the resulting increase in associated costs. The term and cost of the works may be affected again in the future as a result of the measures that may be imposed regarding the evolution of the country's health situation.

Impairment in the value of non-financial assets

In the second quarter of 2021, the remuneration scheme for the energy sold in the spot market was modified by SE Resolution No. 440/21 published on May 19, 2021 (see Note 2.1), which impacted on the future income to be collected by CTB after the termination, in the year 2022, of the supply agreement with CAMMESA remunerating the units that are part of the open cycle. Additionally, the progress of works for CTB's closing to combined cycle was affected, in 2020 and 2021, by the measures implemented to contain the spread of COVID-19, delaying the scheduled term for commissioning and increasing the costs associated with the completion of the project.

In view of these indications, CTB updated, as of June 30, 2021, the estimation of the recoverable amount determined as of December 31, 2020.

The projections used by CTB in the calculation of the recoverable amount as of June 30, 2021 take into consideration 2 scenarios that weigh: i) the entry into effect of the new supply agreement with CAMMESA for the closed cycle; ii) the price restructuring for the spot energy, which is adjusted for inflation on an annual basis; iii) the regularization of the financing term granted to CAMMESA in 2022/2023, after reaching an average term of 100 days; and iv) a 10.3% WACC rate after taxes.

As of June 30, 2021, CTB has not recorded impairment losses as a result of the performed assessment of recoverability.

5.2.4 Investment in OCP

Contingent liabilities

The constitutional protection proceeding brought against OCP by several organizations and natural persons alleging the infringement of several constitutional rights upon the occurrence of the Force Majeure event in 2020 was denied in the second instance by Orellana's Provincial Court of Justice. As of the date of issuance of these Consolidated Condensed Interim Financial Statements, the plaintiffs have filed a constitutional protection proceeding, which has been admitted to be heard by the Constitutional Court.

5.2.5 Investment in Citelec

Service outage in the Argentine Electricity Grid ('SADI')

The total outage in the SADI service, which took place on June 16, 2019, had an impact in 2020 on the amount of both penalties, which were increased, and awards, which were reduced, pursuant to the Additional Service Quality and Penalties Regime established by Resolutions No. 552/16 and No. 580/16.

As a result of this event, Transener set up a provision in the amount of $ 6.6 million plus interest. On May 14, 2021, the ENRE, pursuant to Resolution No. 121/21, imposed a penalty on Transener for the previously described event, which does not significantly differ from the provision held by Transener under liabilities.

Moreover, the ENRE filed new charges against Transener on account of its liability for alleged breaches in this event. Transener rejected the charges alleging the illegality and irrationality of the filing of a new summary proceeding after the termination of the proceeding that imposed the applicable penalties. If this proceeding is resolved unfavorably for Transener, any penalty or other monetary fine may have an adverse impact on its results. As of the date of issuance of these Consolidated Condensed Interim Financial Statements, there is uncertainty on the possible imposition of a penalty and its amount.

Financial loans

In the month of July, 2021, Transener signed a loan agreement with Banco de la Nación Argentina in the amount of $ 1,000 million, for a term of three years and at a BADLAR rate +8%, with the principal being amortized in monthly consecutive installments using the German system, and which will be destined to working capital. In this respect, it is worth highlighting that, according to what has been timely requested by the bank, while the loan remains outstanding, Transener's Board of Directors has committed not to make any proposal to the Shareholders' Meeting regarding the release of Transener's reserves for their distribution as dividends to shareholders or, in case there are negative results affecting reserves and while the loan remains outstanding, not to propose the distribution of earnings until reserves have been replenished up to current levels.

NOTE 6: RISKS

6.1Critical accounting estimates and judgments

The preparation of these unaudited consolidated condensed interim financial statements requires the Company's Management to make future estimates and assessments, to apply critical judgment and to establish assumptions affecting the application of accounting policies and the amounts of disclosed assets and liabilities, and income and expenses.

Mentioned estimates and judgments are evaluated on a continuous basis and are based on past experiences and other reasonable factors under the existing circumstances. Actual future results might differ from the estimates and evaluations made at the date of preparation of these unaudited condensed interim financial statements.

In the preparation of these unaudited condensed interim financial statements, management judgements on applying the Company's accounting policies and sources of information used for the respective estimates are the same as those applied in the Financial Statements for the year ended December 31, 2020 , except for the following information:

6.1.1 Impairment in the value of non-financial assets

The Company regularly monitors the existence of events or changes in circumstances which may indicate that its non-financial assets' book value may not be recoverable, or the possible reversal of losses from the impairment of non-financial assets.

In the Power Generation segment, revenues from the energy sold in the spot market were modified by SE Resolution No. 440/21, which provided for a 29% increase in the remuneration applicable as from February 1, 2021 for generators, as the Company and its subsidiaries, meeting the established requirements, and repealed the application of the automatic adjustment mechanism established by SE Resolution No. 31/20 (see Note 2.1.3).

It is worth highlighting that the most significant share of revenues in the Power Generation segment comes from energy remunerated under a differential scheme (that is, supply agreements with large users in the MATER, Energía Plus or supply agreements entered into with CAMMESA), which have not been affected by the previously mentioned regulations.

In view of the above-mentioned indications, the Company has updated, as of June 30, 2021, its estimates on the recoverable amount of the CGUs making up the Power Generation segment assessed as of December 31, 2020.

The methodology used in the estimation of the recoverable amount consisted of calculating the value in use of each CGU based on the present value of future net cash flows expected to be derived from the CGU, discounted with a rate reflecting the weighted average cost of the capital employed.

Cash flows were prepared based on estimates on the future behavior of certain variables that are sensitive in the determination of the value in use, including the following: (i) reference prices for energy sold in the spot market; (ii) projections of availability and dispatch by the power plants; (iii) costs evolution; and (iv) macroeconomic variables, such as inflation and exchange rates, etc.

For the six-month period ended June 30, 2021, presented in comparative format

(In millions of Argentine Pesos ('$'))

NOTE 6: (Continuation)

The projections used in the calculation of the recoverable amount of the CGUs of the Power Generation segment as of June 30, 2021 take into consideration 2 scenarios that weigh: i) the annual price update, ranging between 80% and 100% compared to the annual inflation; ii) the regularization of the financing term granted to CAMMESA in 2022/2023, after reaching an average term of 100 days; and iii) a 10.3% WACC rate after taxes.

Actual values may substantially differ from projections, mainly on account of: i) the timeliness and magnitude of the increases in the prices of energy, and/or ii) the date of regularization of the financing term granted to CAMMESA. Even though this variation has been taken into consideration when weighing the scenarios, the Company estimates that any sensitivity analysis that considers changes in any of the estimates taken individually may lead to distorting conclusions, generating an adverse effect on the Company's results.

As of June 30, 2021, the value of the assets in the Power Generation segment does not exceed its recoverable amount, with the exception of the Diamante hydroelectric power plant, which assessment of recoverability resulted in the recognition of impairment losses in the amount of $ 172 million (US$ 1.8 million).

6.2 Financial risk management

The Company's activities are subject to several financial risks: market risk (including the exchange rate risk, the interest rate risk and price risk), credit risk and liquidity risk.

No significant changes have arisen in risk management policies since last year.

It should be noted that the Company operates in an economic context which main variables have recently suffered significant volatility as a result of political and economic events both domestically and internationally, as described in Note 1.2.

Provision for contingencies

As of the date of issuance of these Consolidated Condensed Interim Financial Statements, the Company has recorded provisions at the best estimate of the disbursements necessary to meet the claims associated with the progress of the procedural stages of the following proceedings:

(i) On April 30, 2021, Petrobras Operaciones S.A. ('POSA') filed its claim memorial in the international arbitration proceeding brought by POSA against the Company for alleged breaches to the Agreement for the transfer of the 33.6% interest in the 'Río Neuquén' Concession.
(ii) On April 29, 2021, the Company submitted its claim memorial and Petrobras International Braspetro B.V. ('PIB BV') filed its counter-memorial in the international arbitration proceeding brought by the Company against PIB BV, and the counterclaim filed by the latter. On July 7, 2021, the Company submitted its answer to the counterclaim, whereas PIB BV filed its answer to the complaint.

Provision for environmental remediation expenses

The Province of La Pampa has submitted a claim to the Company regarding the abandonment of certain wells and the execution of certain tasks associated with the relinquishment of the Jagüel de los Machos and Medanito blocks (which took place in 2015 and 2016, respectively).

The Company has challenged the different administrative acts passed by the provincial authorities (including the governor's executive order) and is addressing claims for the Jagüel de los Machos block in the judicial jurisdiction. Even though the province answered the complaint in the month of March, the Company has started negotiations to resolve the dispute, agreeing on the suspension of procedural time limits.

NOTE 12: (Continuation)

The techniques used for the measurement of assets at fair value with changes in income, classified as Level 2 and 3, are detailed below:

- Derivative Financial Instruments: calculated from variations between market prices at the closing date of the period, and the amount at the time of the contract.

- Shares: it was determined using the income-based approach through the 'Indirect Cash Flow' method, that is, the net present value of expected future cash flows, mainly through the collection of dividends taking into consideration the 4.04% and 4.55% equity interest, both direct and indirect, in TSM and TMB, respectively, resulting from the Federal Government's restructuring of assets in the energy sector detailed in Note 2.1.4 and a 13.3% discount rate. The used projections were prepared based on estimates on the future behavior of certain sensitive variables, including: (i) the dividend distribution policy; (ii) reference prices for energy sold in the spot market; (iii) projections of the availability and dispatch of power plants; (iv) the evolution of structural costs and expenses; (v) macroeconomic variables such as inflation and exchange rates, etc. As of June 30, 2021, the Company recognized profits as a result of changes in the fair value of financial instruments classified as level 3 in the amount of $ 1,247 million (US$ 13 million), under the item 'Other financial results' of the Consolidated Condensed Interim Statement of Comprehensive Income and other comprehensive income in the amount of $ 129 million. Actual values may substantially differ from projections, mainly on account of: i) the timeliness and magnitude of the distribution of dividends, ii) the timeliness and magnitude of energy price updates, and/or iii) the evolution of costs. The Company estimates that any sensitivity analysis that considers changes in any of the estimates taken individually may lead to distorting conclusions, generating an adverse effect on the Company's results.

NOTE 13: EQUITY COMPONENTS

13.1 Share Capital

As of june 30, 2021, the capital stock amounts to $ 1,399 million, including $ 4 million of treasury shares.

13.1.2 Capital stock reduction

On April 29, 2021, the Company's General Ordinary and Extraordinary Shareholders' Meeting resolved to reduce its capital stock through the cancellation of 57 million shares, which is pending registration with the Public Registry.

13.2 Earning per share

Basic earnings per share are calculated by dividing the result attributable to the Company's equity interest holders by the weighted average of outstanding common shares during the year. Diluted earnings per share are calculated by adjusting the weighted average of outstanding common shares to reflect the conversion of all dilutive potential common shares.

Potential common shares will be deemed dilutive only when their conversion into common shares may reduce the earnings per share or increase losses per share of the continuing business. Potential common shares will be deemed anti-dilutive when their conversion into common shares may result in an increase in the earnings per share or a decrease in the losses per share of the continuing operations.

The calculation of diluted earnings per share does not entail a conversion, the exercise or another issuance of shares which may have an anti-dilutive effect on the losses per share, or where the option exercise price is higher than the average price of ordinary shares during the period, no dilutive effect is recorded, being the diluted earning per share equal to the basic. As of June 30, 2021 and 2020, the Company does not hold any significant potential dilutive shares, therefore there are no differences with the basic earnings per share.

NOTA 18: INCIDENT AT CENTRAL TÉRMICA GENELBA

On May 31, 2021 an incident occurred in the GEBATG03 (TG21) unit, which makes up Central Térmica Genelba's Genelba Plus combined cycle, and damage was caused to the unit's turbine. As a result of the incident, the combined-cycle generation capacity was reduced by approximately 50% (280 MW).

Jointly with the turbine's manufacturer (SIEMENS), the Company performed the necessary works to dismantle and repair the failure, which were completed in July 2021.
