Acquisition and sale of equity interests

5.1.1

Sale of equity interests of controlling stake in Edenor

On December 28, 2020, the Company entered into with Empresa de Energía del Cono Sur S.A. and Integra Capital S.A., Daniel Eduardo Vila, Mauricio Filiberti and José Luis Manzano (the “Purchaser”) a share purchase agreement whereby it agreed to sell its controlling interest in Edenor through the transfer of all Class A shares representing 51% of the capital stock and voting rights of said company (the “Transaction”). On February 17, 2021, Pampa’s shareholders meeting was held and the Transaction was approved.

On June 24, 2021, the ENRE approved the Transaction through Resolution No. 207/21, whereas, after meeting the precedent conditions, the transaction closing took place on June 30, 2021, with the transfer of shares and the change of controlling shareholder.

The agreed sales price consisted of: 21,876,856 Class B shares of Edenor, representing 2.41% of Edenor’s capital stock and voting rights, transferred upon the execution of the share purchase agreement; and US$ 95 million in cash, which was paid in 3 installments: (i) US$ 5 million upon the execution of the share purchase agreement; (ii) US$ 50 million on the closing date; and US$ 40 million, plus interest at a 10% fixed nominal annual rate (payable quarterly), between June and July 2022.

Within the previously described framework and pursuant to IFRS 5, and considering that the transaction involved loss of control over the subsidiary, all Edenor’s assets and liabilities had been classified as held for sale as of December 31, 2020 and had been measured at the lower between its fair value, net of costs associated with the sale, if applicable, and its book value, which involved the recognition of an impairment loss for US$ 589 million, included together with the results corresponding the Distribution of energy segment under “Discontinued operations” of the Consolidated Statement of Comprehensive Income for the years ended December 31, 2021 and 2020.

⁽²⁾ The fair value of this intangible asset regarding the identified business transactions has been determined through the application of the “income-based approach” and the “multi-period excess earnings” method. Key assumptions used considered: i) projected generation level; and ii) discount rate. The useful life was assessed based on the remaining years of the contract.

⁽³⁾ For acquired trade receivables, contractual value does not differ from fair value.

⁽⁴⁾ No differences in the acquired assets’ accounting valuation were identified, except for the values detailed under Property, plant and equipment and Intangible assets.

Expenses related to the acquisition transaction were non-significant, therefore they were recognised as expenses in fiscal year result.

The acquisition contributed to the Group revenues from sales for US$ 11.3 million and net earnings for US$ 3.5 million for the August 12 - December 31, 2022 period.

If the acquisition had taken place on January 1, 2022, the consolidated revenues from sales and the results for the period as of December 31, 2022 would have been US$ 1,844 million and US$ 459 million, respectively. The pro forma information was calculated based on the Company and Greenwind’s results.

The Company paid US$ 20.5 million for the acquisition of the additional equity interest which, net of the cash and cash equivalents balance of US$ 3.1 million, results in a net cash flow of US$ 17.4 million, which is disclosed in the consolidated statement of cash flows in the item “Payment for the acquisition of subsidiaries and associates” under investment activities.

5.1.4 Acquisition of Autotrol Renovables S.A.

On September 30, 2022, the Company acquired 100% of the capital stock of Autotrol Renovables S.A., an entity holder of the “Wayra I Wind Farm” project (registered with the National Renewable Energy Projects Registry, “RENPER”) for a price of US$ 50 thousand.

5.1.5 Acquisition of VAR

On December 12, 2022, Parque Eólico Arauco S.A.P.E.M. (“PEA”) and the Company executed an agreement to acquire 100% of VAR’s capital stock.

Upon the meeting of the precedent conditions, on December 16, 2022, PEA transferred VAR’s shares, and the Company paid US$ 128.1 million, an amount that considers the working capital adjustment estimated on that date. The amount paid is currently under review by the Company and PEA in accordance with the processes established in the share purchase agreement to assess the amount of VAR’s working capital adjustment as of closing. The following table details the fair value of the consideration transferred, and the fair values of the assets acquired and liabilities assumed as of, December 16, 2022:

5.2.3 Investment in CTB

On June 26, 2019. the acquisition by CTB, a company co-controlled by YPF and Pampa, of CTEB's goodwill was perfected, which is located at the petrochemical complex of the town of Ensenada, Province of Buenos Aires, consists of two open-cycle gas turbines, and has a 567 MW installed capacity.

CTB committed to obtain the commissioning of the closing of the combined cycle increasing the installed power capacity to 847 MW.

Both the open and the closed cycle have effective power purchase agreements with CAMMESA under Resolution SE No. 220/07: the first one, entered into on March 26, 2009 which expired on April 27, 2022, and the second one dated March 26, 2013 for a term of 10 years as from the commercial operation of the combined cycle, which stared operations on February 22, 2022. Moreover, energy not committed under contracts with CAMMESA is remunerated at the spot market.

CTEB will be managed and operated by Pampa and YPF on a rotational basis over 4-year periods. Pampa is responsible for managing CTEB’s operations until mid-2023. And YPF, through its subsidiary YPF Energía Eléctrica S.A., will supervise the necessary works for the closing of the combined cycle.

5.2.3.1 Financial Trust Agreement

As a result of the award of CTEB’s goodwill, certain amendments were made to the Enarsa-Barragán Financial Trust Agreement entered into between BICE Fideicomisos S.A. (Nación Fideicomisos S.A.’ continuing company), acting as Trustee, and CTB, in its capacity as Trustor substituting IEASA (former ENARSA) (the “Trust Agreement” or the “Trust”).

Under the Trust, on April 25, 2011 publicly traded Series B VRD for a face value of 582,920,167 were issued. The Trust’s underlying flow is made up of the collection rights resulting from the power supply agreements originally entered into between ENARSA (currently IEASA) and CAMMESA.

On June 26, 2019 and October 16, 2020, CTB made a partial early redemption of 109,628,836 and 275,053,045 outstanding Series B VRD, which were canceled on October 29, 2019 and December 4, 2020, respectively.

Finally, on December 17, 2021, CTB performed the total early redemption of 198,238,286 VRD for a total amount of US$ 94 million. As of the issuance of these Consolidated Financial Statements, the VRD have been canceled and the Trust has been liquidated.

5.2.3.2 Syndicated loan

On March 25, 2022 CTB and the lenders executed a amendment to the agreement modifying the loan repayment scheme in its variable interest rate tranche, with a new maturity on October 1, 2022, and changing the reference rate from LIBOR to SOFR.

During the fiscal year ended December 31, 2022, CTB has repaid at maturity the amount of US$ 74,4 million of the syndicated loan´s remaining installments.

5.2.3.4 Global Program of CB

On July 23, 2020, CTB’s Extraordinary General Shareholders’ Meeting resolved to approve the creation of a global program of simple corporate bonds non-convertible into shares for up to US$ 200 million or its equivalent in other currencies or units of value, and the issuance of corporate bonds under such program up to its maximum amount, at any time, to be issued in one or more classes and/or series, which authorization was granted by the CNV on September 24, 2020.

5.2.3.5 Issuance of CB

On June 4, 2021, CTB issued: (i) Class 1 CB 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 CB for a total amount of 37,504,954 units of purchasing power (“UVA”), 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.

All CB are secured by a personal guarantee subject to a precedent and subsequent condition granted by YPF and Pampa.

As of the date of issuance of these Consolidated Financial Statements, CTB is in compliance with all the covenants under its debt agreements.

5.2.3.6 Closing to combined cycle project

CTB’s closing to combined cycle commitment to increase its installed capacity from 567 MW to 847 MW has been affected from its beginning by the evolution of the measures associated with the COVID-19 pandemic. The stiffening of social lockdown measures from July 1, 2020 excluded private infrastructure works from the exempted activities. Later on, pursuant to Resolutions No. 1197-MJGM-2020 and No. 1690-MJGM-2020 issued by the Buenos Aires Chief of the Cabinet of Ministers’ Office, as amended, CTB resumed the execution of construction works following their critical path from July 20, 2020.

Within this framework, on July 28, 2020, the Company and the Joint Venture made up of SACDE Sociedad Argentina de Construcción y Desarrollo Estratégico S.A. and Techint Compañía Técnica Internacional S.A.C.E.I. entered into an addendum to the construction agreement within the framework of the restrictions imposed as a result of the COVID-19 pandemic, reaching an agreement on the impact on costs and works’ execution terms, and launching a new stage for the execution of the closing to combined cycle.

The evolution of the Argentine Government’s measures to contain the spread of COVID-19 in 2020 and 2021 has affected the works execution progress, delaying the term initially planned 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. Moreover, exchange and customs restrictions have impacted costs and terms for the supply of foreign equipment.

Given the problems in the normal execution of the project affecting the works’ terms and costs, on July 1, 2022, CTB and the Joint Venture made up by SACDE and Techint Compañía Técnica Internacional S.A.C.E I. entered into a new addendum to the construction agreement, which mainly stipulated as follows: (i) a new work schedule to reach the combined cycle’s commissioning; and (ii) the recognition in favor of the Joint Venture of the right to an US$8 million compensation on account of the incurred term and cost variations.

On January 27, 2023, CTB has launched the CC and on February 22, 2023, it stared operations under the supply agreement with CAMMESA.

5.2.3.7 Impairment of non-financial assets

Spot market prices were modified in May 2021 by SE Resolution No. 440/21, which, although providing for a 29% increase in remuneration, permanently abrogated the application of the automatic adjustment mechanism. This impacted the future flows collectible by CTB after the termination, in the year 2022, of the supply agreement with CAMMESA that remunerates the units making up the open cycle. Additionally, in 2020 and 2021 the progress of works for CTB’s closing to combined cycle was affected by the measures implemented to contain the COVID-19 spread, delaying the scheduled term for commissioning and increasing the costs associated with the completion of the project.

In view of these indications, CTB determined the estimation of the recoverable amount as of December 31, 2022 and 2021.

The methodology used in the estimation of the recoverable amount consisted of calculating the present value of future net cash flows expected to be generated by the CGU, discounted with a rate reflecting the weighted average costs of the capital employed.

The projections used by CTB in the calculation of the recoverable amount as of December 31, 2022 take into consideration 2 scenarios that weigh: i) the entry into effect of the new supply agreement with CAMMESA for the combined cycle in the first quarter of 2023; ii) the periodic price update in line with inflation for the spot remuneration; iii) the recognition of a long-term differential remuneration allowing to make the investments necessary to maintain availability and improve the open cycle’s efficiency; iv) the regularization of the financing term granted to CAMMESA in 2024; and v) an 11.7% after-tax WACC rate.

As of December 31, 2022, and 2021, CTB has not recorded any impairment losses as a result of the performed recoverability assessment.

5.2.4 Investment in OCP

The Company, through PEB, has an equity interest in OCPSA, an oil pipeline in Ecuador that has a transportation capacity of 450,000 barrels/day.

On August 12, 2021, the Company, through its subsidiary PEB, executed an agreement with Occidental International Exploration and Production Company for the acquisition of all the shares of Occidental del Ecuador Inc. (currently Pampa Ecuador Inc.) for US$ 5 million. Pampa Ecuador Inc. holds a 14.15 % equity interest in OCP.

The closing of the transaction involved the recognition of profits for US$ 17.2 million, under IAS 28. The following table details the consideration, the fair value of the acquired assets, and the profit recorded by the Company as of August 12, 2021:

On August 12, 2021, PEB recorded an impairment reversal of US$ 1.6 million, on the interest in OCP, prior to the aforementioned acquisitions, in relation to the estimation of the present value of the future cash flows that were expected to be obtained through the collection of dividends considering the concession term and a discount rate of 15.09 %.

The termination of the oil pipeline concession agreement is scheduled for January 12, 2024, considering the term extension resulting from the suspension of the contractual obligations due to force majeure events. On that date, OCP will transfer and deliver to the Ecuadorian Government or its designee all OCPSA’s shares at no cost, as well as the titles and rights over the oil pipeline’s assets. As of the issuance of these Consolidated Financial Statements, OCPSA is executing the actions defined in the contract to meet the transfer plan.

5.2.4.1 Recoverable value of the investment

The erosion process in the Quijos River course, in the San Rafael sector, on the border of the provinces of Sucumbíos and Napo, Ecuador, caused two force majeure events consisting of the rupture of different oil pipeline tranches and the resulting temporary suspension of the crude oil pumping in 2020 and 2021.

Additionally, on January 28, 2022, a new force majeure event occurred due to a stone landslide causing the pipeline’s rupture at KP96+526. OCPSA started the repairs of the affected pipeline and cleanup and remediation works. The crude oil transportation service was resumed on February 7, 2022.

PEB has performed recoverable amount tests for its investment in OCP as of December 31, 2021, considering the present value of the future cash flows it expects to obtain through the collection of dividends during the concession term, the term extension due to the suspension of contractual obligations resulting from the detailed Force Majeure events and a discount rate of 17.12%. PEB has not recorded any impairment losses as a result of the recoverability assessment performed as of December 31, 2021, and, as of December 31, 2022, has identified no additional indications that may impact the assumptions taken into consideration in the aforementioned assessment.

It is worth highlighting that on February 22, 2023, after the end of the fiscal year, a force majeure event occurred due to the collapse of the bridge over the Marker River, located in El Choco canton, Napo Province. In order to guarantee the continuity of the pipeline’s operations and avoid an environmental incident, OCPSA suspended crude oil pumping and started the complete drainage of the pipeline at KP96+075. Additionally, OCPSA notified the occurrence of the previously mentioned event to the Ministry of Energy and Mines. The crude oil transportation service was resumed on March 2, 2023.

5.2.4.2 Contingent liabilities in OCP

Several organizations and natural persons filed a constitutional protection proceeding against OCPSA, as well as the Ministry of Energy, the Ministry of the Environment and Water, Petroecuador and the Ministry of Health, alleging the infringement of several constitutional rights regarding the force majeure event consisting of the land subsidence and sliding at the Quijos River course, which resulted in the rupture of the pipeline at KP 93+469 in 2020. The safeguard action has been disallowed in the first and second instances by Orellana’s Provincial Court of Justice. As of the date of issuance of these Consolidated Financial Statements, the plaintiffs have filed a constitutional protection proceeding, which has been admitted to be heard by the Constitutional Court.

OCPSA's Management together with its legal advisors have classified an unfavorable ruling as remote, therefore, no provision has been recognized on this matter.

5.2.5 Investment in CITELEC

5.2.5.1 Impairment in the value of non-financial assets in Transener

The projections used by Transener in the calculation of the recoverable amount of long-lived non-financial assets considered 3 weighted alternatives associated with: (i) the status of negotiations with the ENRE; (ii) the Right-of-Use and Associated Maintenance contract; (iii) Transener’s management expectations on the transitional tariff increase to be granted until the conclusion of the new RTI; (iv) Transener’s expectations on the timeliness and outcome of the new RTI process; and (v) the impact of a cost monitoring scheme allowing for bi-annual updates to current tariffs.

As of December 31, 2022 and 2021, the book value of Transener’s long-lived non-financial assets does not exceed their recoverable amount.

5.2.5.2 Distribution of earnings

Regarding the loan agreement executed in July 2021 between Transener and BNA in the amount of $ 1,000 million, for the tree-year term, Transener’s Board of Directors has committed, while the loan remains outstanding, to refrain from making any proposal to the Shareholders’ Meeting regarding the release of reserves for their distribution as dividends to shareholders or, in case there are negative results affecting reserves, from proposing the distribution of earnings until reserves have been replenished.

5.2.6 Investment in CIESA

Impairment of non-financial assets in TGS

Argentina’s main macroeconomic and business variables have deteriorated since August 2019. This situation worsened in 2020 due to the negative consequences of the COVID pandemic on the Argentine economic situation, which forced the Argentine Government to take a series of measures, even affecting the regulatory framework of the natural gas transportation segment. As a result, TGS has re-estimated the cash flows used in determining the recoverable value (value in use) of the CGU in the Natural Gas Transportation segment.

The projections used in the calculation of the recoverable amount considered 3 weighted alternatives associated with: (i) the status of negotiations with the Argentine Government; (ii) the contractual rights resulting from the license; (iii) expectations on the transitional tariff increase to be granted until the conclusion of the new RTI; (iv) expectations on the result of the new RTI process; and (v) the impact of a cost monitoring scheme allowing for bi-annual updates to current tariffs.

As of December 31, 2022 and 2021, TGS has determined that it is not necessary to record an additional impairment charge, nor to reverse the recorded one.
