NOTE 1: GENERAL INFORMATION

1.1 General information of the Company

The Company’s principal executive office is located in Maipú 1, Autonomous City of Buenos Aires in Argentina, which participates in the energy sector, mainly in the production of oil and gas and power generation.

In the oil and gas segment, the Company develops an important activity in gas and oil exploration and production, reaching a production level in the six-month period ended June 30, 2025 of 12.4 million m3/day of natural gas and 5.4 thousand bbl/day of oil in 11 productive areas and 2 exploratory areas in Argentina. Its main production blocks are located in the Provinces of Neuquén and Río Negro.

In the generation segment, the Company, directly and through its subsidiaries and joint ventures, has a 5,472 MW installed capacity as of June 30, 2025, which represents approximately 13% of Argentina’s installed capacity, and being one of the largest independent generators in the country.

In the petrochemicals segment, the Company operates 2 high-complexity plants in Argentina producing styrene, synthetic rubber and polystyrene, with a share ranging between 89% and 98%, in the domestic market.

Finally, through the holding, transportation and others segment, the Company participates in the electricity transmission and gas transportation businesses. In the transmission business, the Company jointly controls Citelec, which has a controlling interest in Transener, a company engaged in the operation and maintenance of a 22,349 km high-voltage electricity transmission network in Argentina with an 86% share in the Argentine electricity transmission market. In the gas transportation business, the Company jointly controls CIESA, which has a controlling interest in TGS, a company holding a concession for the transportation of natural gas with 9,248 km of gas pipelines in the center, west and south of Argentina, and which is also engaged in the processing and sale of natural gas liquids through the Cerri Complex, located in Bahía Blanca, in the Province of Buenos Aires, in addition to shale gas transportation and conditioning at Vaca Muerta. Additionally, the segment includes advisory services provided to related companies.

1.2 Economic context in which the Company operates

The Company operates in a complex economic context which main variables are experiencing volatility as a result of political and economic events both domestically and internationally.

As part of the economic stabilization plan, on April 11, 2025 the Government announced measures to ease the exchange rate regime and strengthen the monetary system. These measures were promoted to achieve the priority objective of reducing inflation, boosting economic activity, increasing monetary predictability and building up freely available reserves to support the Government’s economic program. This program is financially backed by a new US$ 20 billion funding facility agreed with the International Monetary Fund, among other agreements. Together, these agreements could potentially contribute to a US$ 23.1 billion increase in BCRA’s net reserves during 2025. As a result, inflation has slowed, with monthly figures below 2% in May and June 2025, and the local primary fiscal surplus has been maintained.

2.2 Generation

2.2.1 Modifications to the electricity regulatory framework

In line with the objective of ensuring free contracting in the MAT established by Law No. 27,742, on January 28, 2025, SE Resolution No. 21/25 was published establishing different modifications regulating dispatch and operation at the WEM’s MAT. The main modifications include:

  • Generators, self-generators and co-generators of conventional thermal, hydraulic and nuclear sources commissioned as from January 1, 2025 are exempted from the suspension of contracting within the MAT;

  • The presentation or renewal of Energy Plus contracts is limited until October 31, 2025, after the expiration of such contracts the Energy Plus market will no longer be in effect;

  • The dispatch scheme set by SE Resolution No. 354/20 is abrogated, effective as from February 1, 2025, and no alternative dispatch scheme is established contemplating the obligations under ENARSA’s supply contract with Bolivia and contracts within the GasAr Plan’s framework;

  • As from March 1, 2025, the recognition of fuel costs is authorized according to reference prices and the values declared and accepted in the Production Cost Statement plus freight, natural gas transportation and distribution costs, and taxes and fees.

  • CAMMESA will continue centralizing fuel supply for contracts entered into under specific schemes (SE Resolutions No. 220/07, No. 21/16 and No. 287/17);

  • generators remunerated under the spot scheme will be able to manage their own fuel, with CAMMESA remaining as the supplier of last resort; and

  • new values are established for the cost of non-supplied energy, effective as from February 1, 2025, under the following tiers: (i) US$ 350 /MWh up to 5%; (ii) US$ 750 /MWh up to 10%, and (iii) US$ 1,500 /MWh for more than 10%.

CAMMESA published the proposal with guidelines contemplating various changes to the WEM structure and remuneration schemes for generation, submitted by the SE pursuant to Note NO-2025-09628437-APN-SE#MEC, and received comments from the Associations representing WEM agents. The reports requested by the SE are pending issuance and will be considered for the passing of transitional WEM adjustment regulations.

NOTE 2**:** (Continuation)

On its part, SE Note NO-2025-35216647-APN-SE#MEC dated April 4, 2025 establishes guidelines for the gas dispatch priority scheme for thermal generation in the WEM. Tenders by generators opting into managing their own fuel supply will be considered firm and, in case of non-compliance, will be subject to a Deliver or Pay penalty equivalent to 70% of the unavailable volume’s reference price.

The new reference price equals 90% of the weighted average price per natural gas basin in the PIST using Round 4.2 prices for the Neuquina Basin and the Norte Basin and Round 4.1 prices for the Austral Basin.

Reference prices for liquid fuels are set for each generator based on international indicators, including a premium covering associated financial and logistical costs, and prices for liquid fuels and natural gas from neighboring countries are recognized at the exchange rate effective on the last business day before the transaction due date, associated with the consumption recognized in the respective economic transaction.

Based on the above-mentioned modifications, CAMMESA made several calls to generating agents for natural gas supply tenders for generation at higher prices.

On May 30, 2025, through Executive Order No. 370/25, the National Government extended the national emergency for the electricity generation, transmission, and distribution segments, and for the natural gas transportation and distribution segments, until July 9, 2026.

On July 7, 2025, through Executive Orders No. 450/25 and No. 452/25, Laws No. 15,336 and No. 24,065 were amended, and the ENRGE was established to replace and unify the ENARGAS and the ENRE, respectively, under the guidelines established in the Bases Law (Law No. 27,742).

Executive Order No. 450/25 establishes a 24-month transition period during which the SE must issue regulations aiming to, among other things:

- decentralize and develop a competitive hydrocarbons market through the free contracting of fuel by generators;
- ensure the regularization and collectability of contracts with electricity distributors, and establish thermal generation remuneration<br>criteria allowing for greater efficiency in fuel procurement;
--- ---
- establish mechanisms for transferring the power purchase agreements executed with CAMMESA to the demand of distributors and large users<br>within the WEM; and
--- ---
- establish mechanisms for transferring the fuel purchase agreements executed by CAMMESA to the WEM´s supply.
--- ---

The following amendments to Laws No. 15,336 and No. 24,065 are noteworthy:

- hydroelectric concessions must have a term (maximum 60 years) and must be re-tendered upon expiration;
- free contracting principles between generators and large users and free users in the WEM must be maintained.

In addition, the SE is empowered to authorize the execution of expansions to the transmission system within an existing concession, after consulting with CAMMESA, and may finance it with FNEE resources. Alternatively, the grid may be expanded on the initiative and at the risk of the party carrying out the expansion, which will be granted priority for the use of the transmission capacity, assignable to third parties.

2.2.2 BESS (Battery Energy Storage Systems) call for tenders

In February 2025, SE Resolution No. 67/2025 launched a national and international call for tenders for up-to-500 MW energy storage projects in the AMBA aiming to improve the electricity grid’s reliability.

The contracts to be executed between distributors and generators will have a maximum 15-year term and provide for a remuneration for power capacity (up to US$ 15,000/MW-month) and energy supplied (US$ 10/MWh), with CAMMESA acting as guarantor of last resort. The commissioning’s target date is scheduled for January 2027.

On July 15, 2025, 27 tenders were submitted for a total 1,347 MW power capacity. Pampa presented a 50-MW project. The award is scheduled for August 29, 2025.

2.2.3 Remuneration at the spot market

SE Resolutions No. 603/24, No. 27/25, No. 113/25, No. 143/25, No. 177/25, No. 227/25, No. 280/25 and No. 331/25, updated the remuneration values for spot generation, providing for 4%, 4%, 1.5%, 1.5%, 2%, 1.5%, 1% and 0.4% increases from the January-August 2025’s economic transactions, respectively. Likewise, the maximum spot price in the WEM was updated to $ 13,487/MWh as from April 2025.

2.3 Gas Transportation

TGS’s Tariff situation

TGS received monthly tariff updates for the January-March 2025 period; to this effect, ENARGAS published transitional tariff charts with 2.5%, 1.5% and 1.7% increases, respectively.

On April 30, 2025, ENARGAS Resolution No. 256/25 established the FTR conditions for the 2025-2030 period. This resolution establishes, among other things, the capital base as of December 31, 2024 and a real after-tax WACC discount rate of 7.18%, used to determine the initial tariff scheme, which includes a 3.67% weighted average tariff update to be implemented in thirty one equal and consecutive monthly installments beginning in May 2025. Likewise, the approval of the monthly tariff update methodology based on price indexes (CPI and IPIM) is postponed.

It also establishes the investment plan for a total of $279,108 million (at June 2024 currency), subject to ENARGAS’ control and the regulated operating expenses for the 2025-2030 five-year period.

Later, through Executive Order No. 371/25, the SE was appointed as the enforcement authority for introducing contractual or tariff modifications. In this regard, SE Resolution No. 241/25 dated June 4, 2025 provided that the periodic transportation tariff update would be monthly, replacing the previous semi-annual scheme. On June 5, 2025, TGS expressed its consent to this resolution, and the tariff schemes were approved through ENARGAS Resolutions No. 350/25, No. 421/25 and No. 539/25, incorporating monthly 2.81%, 0.62% and 1.63% updates in addition to the application of the FTR increases.

License Extension

On July 24, 2025, Executive Order No. 495/25 was published, whereby the PEN extended the license granted to TGS for an additional 20-year period as from December 28, 2027, ratifying the “License Extension Memorandum of Understanding” entered into on July 11, 2025 between the MECON and TGS.

2.4 Transmission

Transener and Transba tariff situation

The ENRE determined the hourly remuneration values, establishing 4%, 4%, 2%, and 4% increases against effective values for the January-April 2025 period for Transener S.A. and Transba S.A.

On April 3, 2025, ENRE Resolution No. 236/25 amended the high-voltage and main electricity distribution utility concessionaires’ return rate defined by ENRE Resolution No. 28/25 dated January 10, 2025 from 6.10% to 6.48% after taxes.

On April 30, 2025, the tariff scheme resulting from the Five-Year Tariff Review process was approved and the ENRE established 42.89% and 10.30% increases against April 2025’s effective tariffs for Transener S.A. and Transba S.A., respectively. Similarly, the ENRE determined the remuneration for independent transmission companies, including Transener S.A., for the operation of the Choele Choel – Pto. Madryn Interconnection and the Fourth Line, and Transba S.A., for the operation of Transportista Independiente de Buenos Aires (TIBA)’s facilities, establishing a tariff equivalent to 77.92%, 100% and 99.73%, respectively, of Transener S.A.’s tariff.

In all cases, the increases apply as follows: 20% as from May 1, 2025, and the remaining 80% on a monthly basis over the June-December 2025 period. Likewise, a monthly tariff update mechanism based on the CPI and IPIM price indexes is provided for.

Consequently, the ENRE established the following increases:

June 2025 July 2025 August 2025
Transener S.A. and the Fourth Line 7.25% 4.64% 6.02%
Transba S.A. 4.06% 1.53% 2.87%
Choele Choel – Pto. Madryn Interconnection 4.35% 1.80% 3.14%
Transportista Independiente de Buenos Aires (TIBA) 7.22% 4.61% 5.99%

NOTE4**:** (Continuation)

As of June 30, 2025, the Company has not early applied the following standards and/or amendments:

- IFRS 18 - “Presentation and Disclosures in Financial Statements”: issued in April 2024. It establishes<br>new presentation and disclosure requirements aiming to ensure that financial statements provide relevant information faithfully representing<br>an entity’s situation. The standard does not affect the recognition or measurement of financial statement items; however, it introduces<br>new requirements for improved comparability among entities. Specifically, the following are worth mentioning: (i) the classification<br>of revenues and expenses into operating, investing and financing categories; (ii) the incorporation of required subtotals; and (iii)<br>the disclosure of performance measures defined by management. The standard applies retroactively to fiscal years and interim periods<br>beginning on or after January 1, 2027, allowing for early adoption. The Company is currently analyzing the impact of the application<br>of the standard on its financial statements’ disclosures.
- IFRS 19 - “Subsidiaries without Public Accountability: Disclosures”: issued in April 2024. It allows for<br>reduced disclosures for entities without public accountability which are subsidiaries of an entity that prepares consolidated financial<br>statements available for public use and comply with IFRS accounting standards. The standard is applicable for periods beginning<br>on or after January 1, 2027, allowing for early adoption. The application of the standard will not have an impact on the Company’s<br>results of operations or financial position.
--- ---
- IFRS 9 and IFRS 7 - “Financial Instruments and Disclosures”: in May 2024, the application guidance for<br>IFRS 9 is modified and disclosure requirements are incorporated into IFRS 7. In particular, it incorporates the option to consider the<br>derecognition of a financial liability before its settlement in case of issuance of electronic payment instructions meeting certain requirements,<br>and incorporates disclosure requirements for investments in equity instruments designated at fair value through other comprehensive income<br>and instruments at amortized cost or fair value through other comprehensive income. The amendments are applicable to fiscal years beginning<br>on or after January 1, 2026, allowing for early adoption. The application of the standard will not have an impact on the Company’s<br>results of operations or financial position.
--- ---
- IMPROVEMENTS TO IFRS - Volume 11: in July 2024, minor amendments are incorporated into IFRS 1, IFRS 7, IFRS 9,<br>IFRS 10 and IAS 7.

5.1.3 OCP
--- ---

Pursuant to the terms and conditions of the concession authorization agreement, OCP caused OCPSA to establish two guarantees, one operational and one environmental, each in the amount of US$ 50 million (including surety bonds provided by the Group as shareholder in the amount of US$ 84 million disclosed within non-current guarantee deposits), which would remain in effect for the term of the agreement and until 90 days after its termination on November 30, 2024. Therefore, the guarantees were scheduled to expire on March 1, 2025, since no claim that may be considered covered within their scope would have been initiated by that date. However, Citibank Ecuador informed OCP that, in its understanding, the guarantees had not expired because OCPSA had not complied with certain required formalities. On its part, OCP has formally notified Citibank Ecuador that its position is incorrect, explaining the reasons for that interpretation. As of the date of issuance of these Consolidated Condensed Interim Financial Statements, OCP has not received a response to this notification.

OCP has also requested the Ecuadorian Government to notify Citibank Ecuador of the guarantees’ expiration, having received no response as of the date of issuance of these Consolidated Condensed Interim Financial Statements.

OCP understands that there is no legal basis for claims under the operational guarantee (to be initiated only in case of a capacity deficiency pursuant to the concession authorization agreement) or under the environmental guarantee (to be initiated only in the event of termination of the concession authorization agreement due to the lack of payment of environmental compensations). In this regard, the guarantees should be terminated and rendered null and void, all in accordance with their terms and conditions.

OCP is taking all necessary actions to terminate the guarantees pursuant to the terms of the concession authorization agreement. On April 11, 2025, OCP filed an arbitration proceeding before the ICSID seeking the effective release of the guarantees and compensation for the damages sustained as a result of the failure to release them; and, subsidiarily, to receive from Ecuador the amount of the guarantees plus interest and damages resulting from Ecuador’s actions. As of the date of issuance of these Consolidated Condensed Interim Financial Statements, the Arbitration Court that will hear the arbitration has been constituted.

5.1.4 CIESA - TGS

On March 7, 2025, heavy rains, unprecedented in the last 100 years, were recorded in the city of Bahía Blanca and adjacent areas, causing flooding in all urban areas and their surroundings.

This event caused the Saladillo García stream to overflow, flooding the Cerri Complex and, consequently, halting the production of liquids and partially affecting natural gas transportation services. It is worth highlighting that the external electricity distribution system and the electricity generation and distribution facilities were also affected.

The natural gas transportation service was gradually restored in full, with no significant impact on TGS’s revenues. However, liquid production at the Cerri Complex was interrupted from March 7, 2025 to early May 2025.

In the six-month period ended June 30, 2025, TGS recorded a $ 33,573 million loss for event-related expenses and the impairment of materials and other property, plant and equipment. Even though the Cerri Complex is operating under normal conditions, as of the date of issuance of these Consolidated Condensed Interim Financial Statements, the final cost of the event has not yet been assessed by TGS.

Furthermore, TGS is undertaking preliminary coverage negotiations with insurance companies; therefore, the insurance proceeds’ amount and timing have not been determined as of the date of issuance of these Consolidated Condensed Interim Financial Statements.

Tender for Perito Moreno Gas Pipeline (GPM) Expansion

On May 22, 2025, ENARSA launched a tender to expand the GPM, aiming to increase natural gas transportation capacity from Vaca Muerta by 14 million cubic meters per day. On July 28, 2025, TGS submitted a tender, and the award is scheduled for October 13, 2025.

5.1.5 VMOS

On July 8, 2025, VMOS entered into a syndicated international loan agreement for a total amount of US$ 2 billion with a 5-year term and an interest rate equivalent to SOFR Term plus a 5.50% margin, intended to finance the construction of the Vaca Muerta Oil Sur pipeline. The project requires a total estimated investment of US$ 3 billion and includes a loading and unloading terminal equipped with interconnected mooring buoys, a tank farm, and other associated accessory facilities for exporting oil and liquids through carriers. Likewise, VMOS amended the transportation agreements entered into with its shareholders to align its terms with the financing structure.

As security for the obligations assumed in the loan: (i) VMOS has assigned in guarantee to the banks its collection rights under the transportation contracts entered into with the initial shippers (YPF, Vista, Pampa, PAE, Pluspetrol, Chevron, Shell, Tecpetrol and GyP); (ii) each initial shipper entered into a direct agreement with the banks; and (iii) VMOS’s Class A shareholders (including Pampa) have granted a fiduciary assignment of their shares as collateral for the financing, which shall remain in effect until the completion of the project.

Disbursements may be requested by VMOS on a monthly basis until the earlier of the project completion date or July 31, 2027.

Under the terms of the syndicated loan agreement, VMOS has undertaken certain customary affirmative and negative covenants for this type of transaction.

In addition, the revenues generated from VMOS’ export operations will be credited to an offshore bank account structure, which is managed by a bank acting as collateral agent. Furthermore, a local tariff guarantee trust has been established, under which a branch of Citibank, N.A. acting as trustee, will manage both the local revenues received by VMOS and any funds transferred from abroad.

NOTE 6: RISKS

6.1 Critical accounting estimates and judgments

The preparation of these 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.

Provision for legal proceedings

In the ongoing files before the National Tax Court regarding gasoline exports, where the tax entity challenges the tariff heading assigned by Petrobras Argentina S.A. during the years 2008-2014, eight additional favorable rulings were passed during the period. Out of the total thirteen rulings in favor of the Company, twelve were sustained by the Tax Authority, therefore becoming final and conclusive. In the remaining case, the term for the Tax Authority to submit an appeal is still pending. Attending to the above-mentioned detailed progress, the Company believes that there are grounds to consider that the associated provision is not probable and, consequently, has recorded, during the period a US$ 44 million recovery, including accrued interest.

In the appeal for partial annulment filed by the Company against the Final Award issued in the international arbitration proceeding initiated by POSA, the latter answered the service of notice, and on July 15, 2025, a hearing was held before the National Chamber of Appeals in Commercial Matters.

The techniques used for the measurement of assets and liabilities at fair value through profit and loss, classified as Level 2 and 3, are detailed below:

- Derivative Financial Instruments: calculated from variations between market prices<br>at the closing date of the period, and the amount at the time of the contract.
- Shares: it was mainly determined using the income-based approach through the “Indirect<br>Cash Flow” method, that is, the net present value of expected future cash flows, mainly through the collection of dividends taking<br>into consideration the direct equity interest of 2.84% and 3.19%, and the additional equity interest of 2.18% and 2.46% through HIDISA<br>and HINISA, in TJSM and TMB, respectively, resulting from the Federal Government’s restructuring of assets in the energy sector.<br>This restructuring resulted in TMB’s and TJSM’s share transfer from the Federal Government to ENARSA.

12.8 Hedge accounting

During the first semester of 2025, the Company entered into forward crude oil sale contracts, without physical delivery, and designated a portion of these derivative financial instruments as cash flow hedges.

The Company applies cash flow hedge accounting to certain transactions to manage the international reference price risk associated with a specific volume of forecasted crude oil sales for the May 2025-October 2026 period, thereby ensuring stable cash flows.

As of June 30, 2025, the fair value of forward crude oil sale contracts designated as hedges amounts to an asset of US$ 23 million, recognized in other comprehensive income as the hedge is effective; this amount is expected to be fully reclassified to profit or loss during the July 2025-October 2026 period, as the hedged crude oil sales are recognized in earnings.

The amount reclassified from other comprehensive income to revenue, from designated hedges, generated a US$ 2 million gain during the second quarter of 2025.

The contracts are entered into in markets or with financial institutions with high credit ratings; therefore, the Company considers that there are no significant credit risks to its operations as a result of its derivative activities.

NOTE 13: EQUITY COMPONENTS

13.1 Share Capital

As of June 30, 2025, the capital stock amounts to $ 1,364 million, including $ 4 million of treasury shares.

13.2 Earning per share

Basic earnings per share are calculated by dividing the result attributable to the Company’s equity 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 operations. 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.

| --- |

NOTE13**:** (Continuation)

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, and 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, 2025 and 2024, the Company does not hold any significant potential dilutive shares, therefore there are no differences with the basic earnings per share.

06.30.2025 06.30.2024
Earning attributable to equity holders of the Company 193 367
Weighted average amount of outstanding shares 1,360 1,360
Basic and diluted earnings per share 0.14 0.27

13.3 Distribution of profits

Dividends distributed to individuals, undivided estates or foreign beneficiaries derived from profits generated during fiscal years beginning on or after January 1, 2018 are subject to a 7% withholding tax. The distribution of dividends is made based on the Company’s Stand-Alone Financial Statements which are presented in pesos, the legal currency in Argentina, pursuant to regulatory requirements.

The Company may pay and distribute dividends and any other type of profits to its shareholders, except if: (i) there is an event of breach; or (ii) the Company is not in a position to incur debt under the indentures governing the Class 9, Class 21, Class 23 and Additional Class 23 CB. As of the date of issuance of these Consolidated Condensed Interim Financial Statements, the Company has complied with all commitments set forth in the indentures governing the above-mentioned CB.

NOTE 17: INVESTMENT COMMITMENTS

Rincónde Aranda Development – RDA Midstream Project

On July 1, 2025, Pampa Energía —through its “Pampa Energía_ S.A. - Sucursal Dedicada Midstream RDA” Dedicated Branch, established on May 12, 2025 by the Company’s Board of Directors, submitted its application to opt into the RIGI to develop an oil and gas treatment plant at its Rincón de Aranda field. The project contemplates an estimated US$ 426 million investment, and its entry into operation is scheduled for 2026. Starting in 2027, the Company expects to export crude oil, in line with the strategy to develop Vaca Muerta and strengthen export capacity.

FLNGProject

On May 2, 2025, all conditions precedent to move forward with the FLNG Project were satisfied, including, but not limited to: (i) the final investment decision regarding the “Hilli Episeyo” vessel (“Hilli”); (ii) the submission of the RIGI opt-in application; and (iii) the granting of the LNG Free Export Authorization certificate.

In addition to Hilli, a second vessel, “MKII”, was added to the project. Both will have a processing and export capacity of approximately 6 million tons of LNG per year, equivalent to 27 million m3/d of natural gas, which will position Argentina in the global LNG market and represent an investment of approximately US$ 7 billion over the 20 years of operation across the entire value chain.

Hilli and MKII operations are expected to start at the end of 2027 and 2028, respectively.

The consortium is made up of 20% Pampa, 30% Pan American Energy S.L. (“PAE”), 25% YPF S.A., through its subsidiary Sur Inversiones Energéticas S.A.U. (“SUR”), 15% Wintershall DEA Argentina S.A. (“Wintershall”) and 10% Golar FLNG Sub-Holding Company Limited (“Golar Subholding”), all of which are SESA shareholders.

To supply natural gas to the vessels, SESA entered into 20-year natural gas supply contracts with Pampa, PAE, SUR and Wintershall regarding their participation in SESA. In this respect, for both vessels to operate year-round, SESA contemplates the construction of a dedicated gas pipeline between the province of Neuquén and the Gulf of San Matías in Río Negro.

NOTE 18: INCIDENT AT HINISA

Regarding the severe storm recorded on January 11, 2025 in the Province of Mendoza, which caused significant damage to the Nihuil II and III power plants and forced them out of service, HINISA began the cleanup and remediation process, started repairing perimeter fences and building closures, and initiated the process of sorting materials and tools salvaged from the incident for their classification and disposal with the insurance company. Progress is also being made in awarding the contract for the identification and assessment of damage to the affected equipment.

| --- |

NOTE 18**:** (Continuation)

During the six-month period ended June 30, 2025, HINISA recorded US$ 2 million losses corresponding to incident-related costs.

Besides, HINISA has filed the corresponding claim with the insurance companies and, as of June 30, 2025, has received advances of US$ 2 million, which disclosed under insurance recovery line item, to carry out the cleanup tasks necessary to determine the final damages and costs.

As of the date of issuance of these Consolidated Condensed Interim Financial Statements, the final cost of the incident and the amount of insurance proceeds have not yet been assessed by HINISA.

NOTE 19: TERMINATION OF HYDROELECTRIC CONCESSIONS

On March 8, 2025, the Federal Government and the province of Mendoza signed an agreement to jointly conduct the national and international open call for tenders for the concession of the Diamante and Nihuiles Hydroelectric Complexes as a single business unit. The coordination and execution of this tender process was delegated to the Public Enterprises Transformation Agency, which, within a maximum 60 business days’ period, would transfer 51% of the share package of the company becoming the concessionaire and owner of the assets.

Subsequently, on June 5, 2025, SE Resolution No. 240/25 extended the transition period for the HIDISA concession until October 19, 2025.

Additionally, on May 26, 2025, Provincial Law No. 9,630 was published, declaring a state of emergency for the Los Nihuiles Hydroelectric System over a 14-month period from its enactment. The Law provides for the continuity of the transition period until verification of compliance with the obligations arising from the concession contract with HINISA, without prejudice to any authorizations that must be granted by the Federal Government.

It is worth highlighting that HINISA has fully and timely complied with its obligations throughout the term of the concession contract and the transition period; and that, as of the date of issuance of these Consolidated Financial Statements, the Federal Government has not issued any statement or granted the required authorizations.

In these circumstances, at the end of the contractual transition period on June 1, 2025, HINISA notified both the Ministry of Energy and Environment of the Province of Mendoza and the SE that the extension of the transition period beyond the term stipulated in the contract requires an agreement with the concessionaire. However, to protect the concession’s assets, avoid affecting the supply of electricity in the WEM and ensure the safety of property and persons, HINISA informed that it would continue operating the Los Nihuiles Hydroelectric Complex, without this implying consent to any unilateral extension of the transition period, the assumption of additional obligations or responsibilities, or the waiver of its rights.

Finally, it is worth highlighting that HINISA is willing to proceed with the assets’ handover as soon as the competent authorities so decide and/or to execute the necessary agreements given this extraordinary situation.
