(“CVOSA”), whose purpose was the management of the construction and currently the operation of a combined-cycle power plant, with a capacity of 816 MW. On July 19, 2018, the National Gas Regulatory Authority (Enargas) registered the Company in the Enargas Registry of Traders and Trading Agreements. Later, on March 22, 2024, the controlled company Puerto Energía S.A.U. was also registered as a natural gas trader in said registry, and on September 20, 2024, it was authorized to join the Wholesale Electricity Market (“MEM”) as a Commercial Participant. Through Proener S.A.U., a company fully controlled by CPSA, the Group participates in the forestry sector since Proener S.A.U. is the controlling company of: a) Forestal Argentina S.A., owner of forestry assets consisting of approximately 141,000 hectares in the provinces of Entre Ríos and Corrientes, of which approximately 77,500 hectares are considered plantable, and approximately 67,000 hectares are currently planted with eucalyptus and pine; and b) Loma Alta Forestal S.A., owner of forestry assets consisting of approximately 19,400 hectares in the province of Corrientes, of which approximately 10,400 hectares are planted with pine. Also, the Group has begun to participate in the mining sector through an equity interest in the Diablillos silver and gold mining project located in northwestern Argentina and an equity interest in the Tres Cruces lithium mining project located in the province of Catamarca. Additionally, as from April 2026, the Group has begun to participate in the oil sector through the incorporation of the hydrocarbon concession over the block known as Aguada del Chivato / Aguada Bocarey, located in the Neuquén Basin (see Note 11.2). Lastly, until September 30, 2025, the Group was linked to the natural gas distribution sector in the Cuyo and Central regions of Argentina through its equity investments in the associate companies belonging to the ECOGAS Group. The issuance of the Group’s consolidated financial statements for the six-month period ended June 30, 2026 was approved by the Company’s Board of Directors on August 11, 2026. 1.1. Summary of the Argentine Electricity Market Transactions among different participants in the electricity industry take place through the Wholesale Electricity Market (“MEM”) which is a market in which generators, distributors and large users of electricity buy and sell electricity at prices determined by supply and demand (“Forward Market”) and also, where prices are established on an hourly basis based on the marginal cost of production, represented by the short-term marginal cost measured in the interconnected system (“Spot Market”). CAMMESA (Compañía Administradora del Mercado Mayorista Eléctrico Sociedad Anónima) is a quasi-governmental organization that was established to administer the MEM and functions as a clearinghouse for the different market participants operating in the MEM. Its main functions include the operation of the MEM, the dispatch of generation and the calculation of prices in the Spot Market, the real-time operation of the electricity system and the administration of commercial transactions in the electricity market. After the Argentine economic crisis in 2001 and 2002 and the end of the Convertibility Law, the costs of generators increased as a result of the Argentine peso devaluation. In addition, the price of fuel used for -10 - English translation of the consolidated financial statements originally filed in Spanish with the Argentine Securities Commission (“CNV”). In case of discrepancy, the consolidated financial statements filed with the CNV prevail over this translation CENTRAL PUERTO S.A. generation also increased. The increasing generation costs combined with the freezing of rates for the final user decided at that time by the National Government led to a permanent deficit in CAMMESA’s accounts, which faced difficulties in paying generators for energy purchases. Due to this structural deficit, the Secretariat of Energy issued a series of regulations to keep the electricity system operating despite the deficit. During 2025, following the issuance of National Executive Branch Decree No. 450/2025, amendments and modifications to Electricity Laws No. 15,336 and No. 24,065, which constitute the Electricity Regulatory Framework, were approved pursuant to the delegation established by the “Ley de Bases” (see Note 13). The delegation aimed to restore the objective of reducing the intervention of the National Government in the pricing and contracting system in order to provide greater freedom to private sector participants and enhanced legal certainty to ensure long-term energy supply. In addition, the federal electricity regime was strengthened by preserving the primacy of the national regulatory framework over local provisions, so as not to hinder the free circulation of energy. Accordingly, on October 20, 2025, the Secretariat of Energy issued Resolution No. 400/2025, which approved the “Rules for MEM Normalization and its Progressive Adaptation”, through which the amendments to the MEM regulations set forth in Decree No. 450/2025 were implemented, effective as of November 1, 2025. The main objective of these rules was to reformulate the MEM in order to establish a pricing system based on marginal costs, decentralize fuel management and allow demand to contract its supply through the Forward Market (“MAT”). Provisions on Hydroelectric Power Plants As from July 11, 2023, through successive resolutions issued by the Secretariat of Energy (“SE”), the term to continue the operation of the Piedra del Águila Hydroelectric Power Plant was extended until January 8, 2026. On August 12, 2024, National Executive Branch Decree No. 718/2024 was published in the Official Gazette, which established that the Secretariat of Energy would call for a National and International Public Tender in order to proceed with the sale of the shareholding interests of the companies created for each of the hydroelectric power plants of the Comahue region. On August 20, 2025, Resolution No. 1200 of the Ministry of Economy was published, which initiated the sale of the shareholding interests of the following hydroelectric power plants: (i) Alicurá Hidroeléctrica Argentina S.A., (ii) El Chocón Hidroeléctrica Argentina S.A., (iii) Cerros Colorados Hidroeléctrica Argentina S.A. and (iv) Piedra del Águila Hidroeléctrica Argentina S.A. (“PDAHA”), and approved the Terms and Conditions of the Tender. Within the framework of the tender process, the Ministry of Economy awarded 100% of the shares of PDAHA (the new concessionaire company of the Piedra del Águila Hydroelectric Complex) to CPSA as sole shareholder for a total consideration of USD 245 million. Such amount was paid by CPSA on January 5 and 6, 2026. As a result thereof, and upon compliance with the requirements set forth in the tender process and in the share transfer agreement, on January 9, 2026: (a) the National Government transferred the shares of PDAHA to CPSA; (b) the National Government and PDAHA ratified the terms of the Concession Agreement for the operation of the Piedra del Águila Hydroelectric Complex for a term of 30 years; and (c) PDAHA took possession of the Hydroelectric Complex. -11 - English translation of the consolidated financial statements originally filed in Spanish with the Argentine Securities Commission (“CNV”). In case of discrepancy, the consolidated financial statements filed with the CNV prevail over this translation CENTRAL PUERTO S.A. This transaction was recorded under the account “Piedra del Águila Hydroelectric Concession” in the statement of financial position as of June 30, 2026. 2. Basis of preparation of the consolidated financial statements 2.1. Professional accounting standards applied The Group prepares its condensed consolidated financial statements in accordance with the applicable regulations of the Argentine National Securities Commission (“CNV”) set forth in Chapter III, Title IV of the CNV Regulations (N.T. 2013 as amended). Under Article 1 of this section of the Regulations, issuers of marketable securities must present their condensed consolidated financial statements applying Technical Resolution 26 of the Argentine Federation of Professional Councils in Economic Sciences (“FACPCE”), which provides for the application of the International Financial Reporting Standards (“IFRS”) issued by the International Accounting Standards Board (“IASB”), together with their amendments and IFRS adoption circulars that FACPCE may issue in accordance with such Technical Resolution. In particular, condensed interim financial statements for interim periods must apply International Accounting Standard (“IAS”) 34 “Interim Financial Reporting”. 2.2. Basis of presentation and consolidation These condensed consolidated financial statements for the six-month period ended June 30, 2026 have been prepared applying the financial reporting framework prescribed by the CNV as mentioned in note 2.1. In preparing these condensed consolidated financial statements, the Group has applied the main accounting policies and the significant accounting judgments, estimates and assumptions described in notes 2.3 and 2.4 to the financial statements for the year ended December 31, 2025, already issued, except for matters related to the definition of functional currency, as explained in Note 2.2.1, and those related to the application of IAS 29 “Financial Reporting in Hyperinflationary Economies”. These condensed consolidated financial statements include all the information necessary for a proper understanding by users thereof of the relevant facts and transactions that occurred after the issuance of the last annual financial statements for the year ended December 31, 2025 and up to the date of issuance of these interim condensed consolidated financial statements. However, these condensed consolidated financial statements do not include all the information nor all the disclosures required for the annual financial statements prepared in accordance with IAS 1 (Presentation of financial statements). Therefore, these condensed consolidated financial statements must be read together with the annual financial statements for the year ended December 31, 2025. The Group’s condensed consolidated financial statements are presented in Argentine pesos, which constitute the entity’s presentation currency, while its functional currency is the United States dollar. The process for translating the functional currency into the presentation currency is described in Note 2.2.1. All values have been rounded to the nearest thousand (ARS 000), except when otherwise indicated. 2.2.1. Functional currency The Company has changed its functional currency from Argentine pesos to United States dollars (“USD”) with effect from January 1, 2026, as a result of changes in the relevant facts and circumstances affecting its primary economic environment. -12 - English translation of the consolidated financial statements originally filed in Spanish with the Argentine Securities Commission (“CNV”). In case of discrepancy, the consolidated financial statements filed with the CNV prevail over this translation CENTRAL PUERTO S.A. In particular, the Company considered, among other factors, the modification in the regulatory framework applicable to the electricity market, established by Resolution No. 400/2025 issued by the Secretariat of Energy, which provides that a significant portion of its revenues is denominated in United States dollars. Based on these factors, the Company concluded that, as of January 1, 2026, the United States dollar is the currency of the primary economic environment in which the Company operates. The change in functional currency has been accounted for prospectively from January 1, 2026, in accordance with International Accounting Standard 21 – The Effects of Changes in Foreign Exchange Rates (“IAS 21”). 2.2.2. Presentation currency and translation basis In accordance with Argentine National Securities Commission (“CNV”) General Resolution (“GR”) No. 562, the Group is required to present its financial statements in Argentine pesos as its presentation currency. On the other hand, on November 13, 2025, the International Accounting Standards Board (“IASB”) issued Translation to a Hyperinflationary Presentation Currency – Amendments to IAS 21 (the “Amendments”). The Amendments are intended to improve the usefulness of the resulting information in a cost-effective manner. The Amendments are effective for annual periods beginning on or after January 1, 2027, but may be applied earlier. In this regard, the Group has elected to apply them early during 2026. The Amendments indicate that if an entity’s functional currency is the currency of a non-hyperinflationary economy, but its presentation currency is the currency of a hyperinflationary economy, paragraph 41A of amended IAS 21 requires that its results and financial position be translated into the presentation currency by translating all amounts (i.e., assets, liabilities, equity items, income and expenses) at the closing exchange rate at the date of the most recent statement of financial position. Accordingly, and as a result of the change in functional currency described in Note 2.2.1, the condensed financial statements as of June 30, 2026 prepared in the Group’s functional currency were translated into the presentation currency using the exchange rate as of June 30, 2026, ARS 1,482 per USD 1, for: – all assets, liabilities, income and expenses; and – all equity items, except for “Capital stock – Face value” and “Capital stock – Treasury shares”, which were maintained in historical Argentine pesos, and the effects of the translation were recognized in the “Adjustment to capital stock” and “Comprehensive adjustment of treasury shares” accounts in the consolidated statement of changes in equity, respectively. As mentioned in Note 2.4, comparative financial information as of December 31, 2025 and June 30, 2025 is expressed in the currency of purchasing power as of December 2025 and June 2025, respectively. 2.2.3. Effects of the translation of investments in subsidiaries with a functional currency corresponding to a hyperinflationary economy IAS 21 requires that the financial statements of a subsidiary whose functional currency is that of a hyperinflationary economy be restated in accordance with IAS 29 “Financial Reporting in Hyperinflationary Economies” before being included in the separate financial statements of its parent whose functional currency is that of a non-hyperinflationary economy. -13 - English translation of the consolidated financial statements originally filed in Spanish with the Argentine Securities Commission (“CNV”). In case of discrepancy, the consolidated financial statements filed with the CNV prevail over this translation CENTRAL PUERTO S.A. In accordance with the aforementioned guidelines, the assets, liabilities, income, expenses and equity items of subsidiaries whose functional currency is the Argentine peso were translated into United States dollars at the exchange rate as of the closing date of these financial statements. 2.3. Foreign currency transactions and balances The Group considers as foreign currency transactions all those transactions that have been carried out in a currency other than the functional currency determined by the Group. Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Gains and losses resulting from the settlement of any transaction and from the translation at the closing exchange rate of monetary assets and liabilities denominated in foreign currencies are recognized in the consolidated statement of comprehensive income, unless they are capitalized. 2.4. Comparative information Comparative information as of December 31, 2025 and June 30, 2025 is presented as it was included in the financial statements for such year / period. As a result, such comparative information as of December 31, 2025 and June 30, 2025 is expressed in the currency of purchasing power as of December 2025 and June 2025, respectively. Circumstances such as the change in functional currency mentioned in Note 2.2.1 and those described in the preceding paragraph limit the comparability of the balances as of June 30, 2026 with the corresponding balances as of December 31, 2025 and June 30, 2025. In Note 2.2.2 to the consolidated financial statements for the year ended December 31, 2025, already issued, the effects of the application of IAS 29 up to that date are disclosed. 2.5. Changes in significant accounting policies New standards and interpretations adopted As from the year beginning on January 1, 2026, the Group has applied for the first time certain new and/or amended standards and interpretations as issued by the IASB. In this regard, as mentioned in Note 2.2.2 above, the Company has decided to apply the Amendments to IAS 21 described therein early. A brief description of the new and/or amended standards and interpretations adopted by the Group and their impact on these consolidated financial statements is presented below: Amendments to the Classification and Measurement of Financial Instruments — Amendments to IFRS 9 and IFRS 7 In May 2024, the IASB issued the Amendments to IFRS 9 and IFRS 7, Amendments to the Classification and Measurement of Financial Instruments (the “Amendments”). The Amendments include: -14 - English translation of the consolidated financial statements originally filed in Spanish with the Argentine Securities Commission (“CNV”). In case of discrepancy, the consolidated financial statements filed with the CNV prevail over this translation CENTRAL PUERTO S.A. – The clarification that financial liabilities should be derecognized on the “settlement date” and the inclusion of an accounting policy option (provided that specific conditions are met) to derecognize financial liabilities settled through an electronic payment system before the settlement date. – Additional guidance on how to assess the contractual cash flows of financial assets with environmental, social and governance (“ESG”) features and similar features. – Clarifications regarding what is included in the term “non-recourse features” and what constitutes the features of contractually linked instruments. – The introduction of disclosures about financial instruments with contingent features and additional disclosure requirements for equity instruments classified at fair value through other comprehensive income (OCI). The Amendments have not had a material impact on the Group’s consolidated financial statements. Annual Improvements to IFRS Accounting Standards – Volume 11 In July 2024, the IASB issued nine limited-scope amendments as part of its periodic maintenance of IFRS Accounting Standards. The amendments include clarifications, simplifications, corrections or changes intended to improve the consistency of IFRS 1, First-time Adoption of International Financial Reporting Standards, IFRS 7, Financial Instruments: Disclosures and its related Implementation Guidance, IFRS 9, Financial Instruments, IFRS 10, Consolidated Financial Statements, and IAS 7, Statement of Cash Flows. The amendments have not had a material impact on the Group’s consolidated financial statements. Nature-dependent electricity contracts – Amendments to IFRS 9 and IFRS 7 In December 2024, the IASB issued the Amendments to IFRS 9 and IFRS 7 – Nature-dependent electricity contracts. The Amendments apply only to nature-dependent electricity contracts and: – Clarify the application of the “own use” requirements for contracts within the scope. – Modify the designation requirements for a hedged item in a cash flow hedge relationship for contracts within the scope. – Introduce new disclosure requirements to enable investors to understand the effect of these contracts on the entity’s financial performance and cash flows. The Amendments have not had a material impact on the Group’s consolidated financial statements. -15 - English translation of the consolidated financial statements originally filed in Spanish with the Argentine Securities Commission (“CNV”).

On May 24, 2019, CPRES (a company now absorbed by PERSAU) entered into a loan agreement with Banco de Galicia y Buenos Aires S.A. for an amount of USD 12.5 million to finance the construction of the “La Castellana II” wind farm. According to the terms of the agreement, the loan accrues a fixed interest rate of 8.5% during the first year, increasing by half a percentage point annually until the sixty-first interest period, and is amortizable quarterly in 25 installments starting May 24, 2020. Under the loan agreement, the subsidiary CPRES had committed to maintain certain financial ratios until full repayment of the outstanding amounts. As a result of the corporate reorganization through which CPRES was absorbed by PERSAU, as from June 18, 2025, the ratios to be complied with are those previously mentioned in connection with the loan granted to PERSAU. Furthermore, as collateral for the obligations assumed, the subsidiary PERSAU maintained first-ranking pledges over the financed assets in favor of Banco de Galicia y Buenos Aires S.A. On January 26, 2026, PERSAU and Banco de Galicia y Buenos Aires S.A. agreed to cancel the pledges related to both financings, considering that as of that date only two installments remained for the full repayment of the loans. The cancellation of both pledges took place on February 1, 2026 and March 5, 2026, respectively. Other related agreements and documents, such as the surety (the “Fianza”, under which CPSA fully, unconditionally and irrevocably guaranteed, as principal debtor, all payment obligations assumed by PERSAU and CPRES until full repayment of the guaranteed obligations or until the project reaches the project compliance date, whichever occurs first), share pledge agreements, wind turbine pledge agreements, direct agreements and promissory notes have been executed. On September 3, 2021, PERSAU and CPRES fulfilled all the requirements and conditions necessary to certify the occurrence of the project compliance date, and therefore the Fianza granted by the Company was released. The loan originally entered into by CPRES was fully repaid at maturity on May 26, 2026. As of December 31, 2025, the outstanding balance of these loans amounted to 9,378,822. As of June 30, 2026, the outstanding balance of the loan with PERSAU amounted to 3,321,162; subsequent to the end of the period, such loan was repaid at maturity. -25 - English translation of the consolidated financial statements originally filed in Spanish with the Argentine Securities Commission (“CNV”).

Financial trust corresponding to Thermal Station Brigadier López Within the framework of the acquisition of the Thermal Station Brigadier López, the Company assumed the role of settlor under the financial trust previously entered into by Integración Energética Argentina S.A., which was the former owner of the plant. The financial debt balance at the transfer date of the plant was USD 154,662,725. In accordance with the provisions of the trust agreement, the financial debt accrued an interest rate equal to the LIBOR rate plus 5% or equal to 6.25%, whichever was greater, and was amortized monthly. On April 5, 2022, the outstanding balance was fully repaid. Under the financial trust agreement, as of December 31, 2025, there were trade receivables with specific assignment amounting to 884,757. During December 2024, CPSA initiated arbitration proceedings before the Buenos Aires Stock Exchange to recover the amounts corresponding to the reserve fund and proceed with the subsequent dissolution of the financial trust. In April 2026, the Company was notified of the arbitration award issued by the tribunal, which upheld CPSA’s claim, ordering the reimbursement to CPSA of the amounts held in the reserve fund, adjusted at an annual interest rate of 6%, plus costs. In June 2026, the Company received the amounts corresponding to principal amounting to 6,951,771, while the award of interest was appealed by the defendant. As of the date of issuance of these financial statements, such appeal is pending resolution by the Court of Appeals. 7.3.6. CPSA Notes Program On July 31, 2020, the Extraordinary General Shareholders’ Meeting of the Company approved the creation of a new global program for the issuance of notes for a maximum outstanding amount at any time during the term of the program of USD 500,000,000 (or its equivalent in other currencies), to be issued as short-, medium- or long-term notes, simple, non-convertible into shares, under the terms of the Negotiable Obligations Law (the “Program”). Additionally, the Board of Directors was granted authority to determine and establish the conditions of the Program and of the negotiable obligations to be issued under it, insofar as such conditions were not expressly determined by the shareholders’ meeting. On October 29, 2020, the CNV approved the creation of the aforementioned Program. On June 11, 2025, the CNV approved the extension of the Program’s term until October 29, 2030 and the increase of the Program’s amount up to USD 1,000,000,000. Under this Program, the Company issued four types of securities: (a) on September 17, 2023, the issuance and settlement of Class A Notes took place, denominated, issued, and payable in U.S. dollars abroad; the characteristics of these Notes are as follows: (i) nominal value issued: USD 37,232,818, (ii) interest rate, determined through bidding: 7%, (iii) interest coupon frequency: semiannual, (iv) amortization: bullet, (v) term: 30 months from September 17, 2023, and (vi) applicable law and deposit location: Argentina, Caja de Valores S.A.; (b) on October 17, 2023, the issuance and settlement of the international bond denominated “10% Senior Notes due 2025” (Class B Notes) took place, denominated, issued, and payable in U.S. dollars abroad, under the Reg S scheme.

On October 20, 2023, the Company decided to reopen Class A Notes, a procedure that allows offering in the market a security that replicates all the conditions of the previously offered instrument, incorporating the interest rate determined in the original offering (7%) and bidding the price. As a result of this process, the Company issued an additional USD 10,000,000 for Class A Notes, with an issuance price of 102.9%. Thus, the total nominal value of Class A amounts to USD 47,232,818. On August 28, 2025, the Company decided to reopen Class C Notes, issuing an additional USD 39,067,309 with an issuance price of 100.06%. Therefore, the total nominal value of Class C amounts to USD 89,067,309. On October 17, 2025, Class B Notes were fully canceled. On January 16, 2026, the Company carried out the early redemption of Class A Notes, which included the full repayment of the nominal value and the accrued interest up to that date. 7.3.7. CPSA´s Share Buyback Programs Considering the volatility of the market and the divergence between the Company's share price and the current economic reality of its assets or their future potential, which is detrimental to the interests of the Company's shareholders, and taking into account the Company's strong cash position and availability of funds, the Board of Directors has implemented several share buyback programs, ensuring in each case that treasury shares do not exceed the legal limit of 10% of the issued share capital. On October 13, 2022, the Company’s Board of Directors approved the creation of a share buyback program for the acquisition of the Company’s own shares for a maximum amount of up to USD 10,000,000 and for a period of 180 consecutive days. This program expired on April 11, 2023. Under this program, the Group repurchased 252,034 shares with a nominal value of $1 for a total amount of 254,501. See Note 9. On August 24, 2023, the Company’s Board of Directors approved the creation of a new share buyback program for the acquisition of the Company’s own shares for a maximum amount of up to USD 10,000,000 and for a period of 180 consecutive days. This program expired on February 20, 2024. Under this program, the Group -27 - English translation of the consolidated financial statements originally filed in Spanish with the Argentine Securities Commission (“CNV”). In case of discrepancy, the consolidated financial statements filed with the CNV prevail over this translation CENTRAL PUERTO S.A. repurchased 2,299,993 shares with a nominal value of $1 for a total amount of 4,754,693. The deadline for the disposal of these shares, in accordance with the Capital Markets Law, expires on October 11, 2026. On September 25, 2025, the Company’s Board of Directors approved the creation of a new share buyback program for the acquisition of the Company’s own shares, in accordance with applicable regulations, for a maximum amount of up to USD 20,000,000 and for a period of 180 consecutive days. This program expired on March 24, 2026. Under this program, the Group repurchased 2,756,000 shares with a nominal value of $1 for a total amount of 3,762,901. The deadline for the disposal of these shares, in accordance with the Capital Markets Law, expires on October 17, 2028. The transactions carried out under these programs were recorded as acquisitions of treasury shares in accordance with IAS 32 and applicable CNV regulations; therefore, the consideration paid for such shares was recognized directly in equity. 7.3.8. Mitsubishi Corporation Loan On November 29, 1996, Central Costanera S.A. signed a contract with Mitsubishi Corporation for the installation of a turnkey combined cycle power plant. The original agreement included financing of USD 192.5 million for 12 years from the provisional acceptance of the project, with a fixed annual interest rate of 7.42% and semiannual amortization of principal and interest. On October 27, 2014, Central Costanera S.A. and Mitsubishi Corporation agreed to the restructuring of such liability. Among the main restructuring conditions, the following stand out: waiver of accrued and accumulated interest as of September 30, 2014 amounting to USD 66,061,897; rescheduling of principal of USD 120,605,058 for an 18-year term, with a 12-month grace period, which must be fully repaid before December 15, 2032; a minimum annual payment of USD 3,000,000 in principal, in quarterly installments; a fixed annual interest rate of 0.25%; and certain restrictions on dividend payments. Considering the restrictions imposed at the time by the Central Bank of Argentina (see Note 13), several amendments to the loan agreement have been executed since September 30, 2020. The loan includes certain financial covenants, which as of June 30, 2026, have been fully complied with by Central Costanera S.A. Moreover, as a guarantee of the obligations undertaken, Central Costanera S.A. maintains a first-ranking pledge over the financed asset in favor of Mitsubishi Corporation, the amount of which has varied depending on the refinancing obtained. As of June 30, 2026 and December 31, 2025, the outstanding balance of the liability amounted to 54,279,732 and 48,716,391, respectively. 7.3.9. Loans with IFC and Banco de Galicia y Buenos Aires S.A.

(see Note 1.1) and part of the battery energy storage project at the Nuevo Puerto power plant (see Note 1.2.r of the financial statements for the year ended December 31, 2025, already issued). In accordance with the terms of the agreement, the loan accrues an interest rate equal to SOFR plus 4.00% or SOFR plus 4.15%, depending on the tranche. The term of the loan ranges between 7 and 9 years depending on the tranche and includes a 2-year grace period and quarterly amortizations. Upon execution of the financing -28 - English translation of the consolidated financial statements originally filed in Spanish with the Argentine Securities Commission (“CNV”). In case of discrepancy, the consolidated financial statements filed with the CNV prevail over this translation CENTRAL PUERTO S.A. agreement, certain structuring and syndication costs became due, amounting to USD 5,720,000. Such amount was paid in January and February 2026. As from January 2, 2026, this loan accrues a 1% commitment fee, calculated on the undisbursed balances. CPSA has committed to maintain an “Adjusted Interest Coverage Ratio” of at least 2.00:1.00 and a Net Financial Debt to Adjusted EBITDA ratio (as defined in the loan agreement) not exceeding 3.00:1.00, measured quarterly on a consolidated last twelve months basis. Additionally, the loan agreement establishes other customary obligations and restrictions for financings of this type, which include, among others: (i) certain limitations on consolidations, mergers and asset sales; (ii) restrictions on incurrence of additional indebtedness; (iii) limitations on dividend payments; (iv) limitations on capital expenditures; and (v) restrictions on the creation of liens. The Company received a first disbursement of USD 50 million under the aforementioned loan on April 16, 2026. As of June 30, 2026, the outstanding balance of this liability amounted to 66,049,776. Additionally, on January 5, 2026, the Company entered into a bridge loan agreement with Banco de Galicia y Buenos Aires S.A. for an amount of USD 200 million, at an interest rate of 5% per annum and for a term of 180 days from the disbursement date, which was disbursed on January 6, 2026. In accordance with the provisions of the loan agreement, the funds obtained were used for the acquisition of the shares of Piedra del Águila Hidroeléctrica Argentina S.A. On May 5, 2026, the Company made an early repayment of approximately USD 130 million of this bridge financing. In turn, on June 16, 2026, the Company agreed with Banco de Galicia y Buenos Aires S.A. to extend the maturity date of the loan until August 13, 2026 and to modify the interest rate applicable during the extended period, which was set at 3.5%. As of June 30, 2026, the outstanding balance of this liability amounted to 104,344,656. 7.3.10. Short-term loans for import financing During 2025, CPSA entered into a master agreement with Banco Santander for an amount of up to USD 50,000,000 to finance foreign trade transactions. Between January and March 2026, three disbursements were made for a total of USD 18,606,382, at an average annual interest rate of 6.12%, with maturity in July 2026. These loans were repaid at maturity. Additionally, during 2026, Central Costanera S.A. entered into two master agreements with BBVA for the same purpose, for maximum amounts of up to USD 7,500,000 and USD 17,000,000, respectively. Under the first master agreement, two disbursements were made in January 2026 for a total of USD 6,781,866, at an average annual interest rate of 6.31%, with maturity in July 2026.

Quantitative and qualitative information on fair values Valuation techniques The fair value reported for financial assets represents the amount at which the instrument could be exchanged in a regular transaction between mutually consenting parties, and not in a forced or liquidation transaction. The following methods and assumptions were used to estimate the fair values: Management has assessed that the fair values of current trade receivables approximate their carrying amounts, largely due to the short-term maturities of these instruments. The Group assesses long-term receivables at fixed and variable rates based on discounted cash flows. The valuation requires that the Group adopt certain assumptions such as interest rates, specific risk factors of each transaction and the creditworthiness of the customer. The fair value of quoted debt securities, mutual funds, equity instruments and corporate bonds is based on the quoted prices as of the reporting period end date. The fair value of interest-bearing debts and loans approximates their carrying amount.

In case of discrepancy, the consolidated financial statements filed with the CNV prevail over this translation CENTRAL PUERTO S.A. On April 30, 2026, the Company’s Shareholders’ Meeting approved to allocate the unappropriated earnings as of December 31, 2025 and the portion of the legal reserve exceeding the amount required by applicable regulations and the by-laws, totaling 29,273,279, to the creation of a voluntary reserve to be used interchangeably for (i) dividend payments, based on the evolution of the Company’s financial condition and in accordance with the Company’s current dividend distribution policy, and (ii) the acquisition of the Company’s own shares. Within the framework of the share repurchase program approved by the Company on October 11, 2022 (see Note 7.3.7), and in accordance with Section 67 of Capital Markets Law No. 26,831, 252,034 ordinary shares, each granting one vote, were automatically cancelled. Such cancellation, as required by applicable regulations, was due to the fact that, after the lapse of a three-year period from their acquisition (carried out between October 20 and November 23, 2022), such treasury shares remained in portfolio without having been disposed of or subject to a shareholders’ resolution as to their use. As a result, the Company’s share capital was automatically reduced by an amount equal to the nominal value of the cancelled shares, resulting in a new share capital of 1,513,770, represented by 1,513,770,222 ordinary shares, each with one vote and a nominal value of $1. In this regard, on May 6, 2026, the CNV resolved to partially cancel the public offering authorization with respect to 252,034 shares as a result of the share capital reduction described above. Accordingly, following such cancellation, CPSA’s share capital authorized for public offering amounts to 1,513,770, represented by 1,513,770,222 registered, book-entry ordinary shares, each granting one vote and with a nominal value of $1. The effects of the cancellation of these shares were presented in the statement of changes in equity included in the consolidated financial statements for the year ended December 31, 2025, already issued, within the accounts “Capital stock – Treasury shares”, “Comprehensive adjustment of treasury shares”, “Cost of treasury shares”, with the difference recognized in “Unappropriated retained earnings”.

Terms and conditions of transactions with related parties Balances at the related reporting period-ends are unsecured and interest free. There have been no guarantees provided or received for any related party receivables or payables. For the six-month periods ended June 30, 2026 and 2025, the Company has not recognized any impairment losses on related party receivables. This assessment is undertaken at the end of each reporting period by examining the financial position of the related party and the market in which the related party operates. During the six-month period ended June 30, 2025, the Group sold 0.21% of its equity interest in subsidiaries, without losing control over such entities. In accordance with IFRS 10, the effects of these transactions were recognized directly in equity. On January 7, 2025, the Shareholders’ Meeting of the subsidiary CPR approved the redemption of all shares held by the minority shareholders of said company, with the exception of one share retained by PERSAU, pursuant to Article 220, paragraph 1 of the General Companies Law ("LGS"), and voluntarily reduced the share capital in accordance with Article 203 of the LGS. Subsequently, on March 31, 2025, CPSA acquired from PERSAU the remaining CPR share. In accordance with IFRS 10, the effects of these transactions were recognized directly in equity. On May 7, 2026, the subsidiary Patagonia Energy S.A. received a capital contribution from a minority shareholder in the amount of USD 12,484,600 (see Note 11.2). 11. Contracts, acquisitions and agreements 11.1. Acquisition of interest in 3C Lithium Pte. Ltd. On January 26, 2026, CPSA carried out a share acquisition and subscription at a price of USD 0.70 per share, through which it reached a 35% equity interest in the share capital of 3C Lithium Pte. Ltd. This company holds 100% of the share capital of Minera Cordillera S.A., an Argentine company that holds the mining rights to the “Tres Cruces” project, located in the province of Catamarca, Argentina. The “Tres Cruces” project is a recently discovered lithium deposit aimed at the development of exploration, drilling and mining activities. The Board of Directors of Minera Cordillera S.A. approved the 2026 business plan, which includes specific expenditures, operating expenses strictly related to the development of the “Tres Cruces” project, including exploration activities, working capital, general administrative expenses and legal or banking fees directly associated with the project. 11.2. Acquisition of Patagonia Energy S.A. On April 12, 2026, CPSA entered into an agreement with Patagonia Assets Limited for the direct and indirect transfer of 100% of the share capital of Patagonia Energy & Resources Limited, the parent company of Patagonia Energy S.A. (“PESA”), which holds a hydrocarbon concession over the block known as Aguada del Chivato / Aguada Bocarey, located in the Neuquén Basin. The transfer of such shareholding was completed on April 16, 2026. The agreed purchase price amounted to USD 50,000,000. Within the measurement period provided by IFRS 3, as of the date of issuance of these condensed interim financial statements, the preliminary purchase price allocation has not yet been completed, since the process of identifying and valuing the assets acquired and liabilities assumed is still ongoing. As part of such process, -35 - English translation of the consolidated financial statements originally filed in Spanish with the Argentine Securities Commission (“CNV”). In case of discrepancy, the consolidated financial statements filed with the CNV prevail over this translation CENTRAL PUERTO S.A. intangible assets consisting of hydrocarbon exploration and evaluation assets amounting to 81,969,420 have been identified. On June 16, 2026, PESA entered into a share purchase option agreement in favor of the supplier Radius Energy LLC and certain employees for up to 13% of PESA’s share capital. This agreement did not have a material impact on these financial statements for the six-month period ended June 30, 2026. 11.3. Award of firm natural gas transportation Within the framework of two open tenders, on April 15, 2026, Transportadora de Gas del Sur S.A. (“TGS”) awarded CPSA firm natural gas transportation services for a volume of 436,804 m³/day (Perito Moreno pipeline) and 428,199 m³/day (Neu-Ba pipeline), for a term of 30 years, at a total price of USD 30,727,676 and ARS 9,340,741,550, respectively. Such amounts shall be paid by CPSA in four equal installments in May, September and December 2026, and in April 2027. 12. Tax inflation adjustment Pursuant to Law No. 27,468, as amended by Law No. 27,430, for the determination of the amount of taxable net income for fiscal years commencing on or after January 1, 2019, the inflation adjustment calculated by applying the provisions set forth in the income tax law may be added to or deducted from the taxable result of the fiscal year. This adjustment will only be applicable (a) if the cumulative variation of the consumer price index (“IPC”) during the 36 months prior to the closing of the fiscal year is higher than 100%, and (b) for the first, second, and third fiscal years commencing on or after its entry into force, if the accumulated IPC variation exceeds 100% by 55%, 30% or 15%, respectively. The positive or negative tax inflation adjustment, depending on the case, corresponding to the first, second and third fiscal years commencing from January 1, 2018, which must be calculated in case the conditions mentioned in paragraphs (a) and (b) are met, shall be allocated one-sixth in that fiscal year and the remaining five-sixths, in equal parts over the five immediately following fiscal years. As of December 31, 2019 and during the following fiscal years, such conditions had already been met. Consequently, the current and deferred income tax has been recognized as from the fiscal year ended December 31, 2019, incorporating the effects derived from the application of the tax inflation adjustment in accordance with the provisions of the income tax law. 13. Measures in the Argentine economy On December 10, 2023, new government authorities took office and issued a series of measures, whose main objectives included: regulatory flexibility for economic development, reducing various expenses with the aim of reducing the fiscal deficit, reduction of subsidies, among others. In the context of the new government, in December 2023, a significant devaluation of the Argentine peso occurred, reflected in the official exchange rate. From 2024 onwards, the national government has taken actions to achieve fiscal balance, which allowed it to achieve, in a short period of time, a primary and financial surplus in relation to Gross Domestic Product, and to initiate a process of deceleration of inflation. -36 - English translation of the consolidated financial statements originally filed in Spanish with the Argentine Securities Commission (“CNV”). In case of discrepancy, the consolidated financial statements filed with the CNV prevail over this translation CENTRAL PUERTO S.A. Passing of Law No. 27,742 “Law of Bases” On June 28, 2024, Law No. 27,742 (“Law of Bases”) was enacted, which came into force after its promulgation by the Executive Branch. In the field of energy, the Bases Law modifies laws that form the regulatory framework of hydrocarbons, natural gas, biofuels, electricity, among others. These changes are intended to reconfigure the relationship between the State and the market, with the objective of granting greater prominence to private initiative in order to improve competitiveness and maximize the income obtained. In this regard, the Bases Law empowers the Executive Branch to modify Law No. 15,336 on Electric Energy and Law No. 24,065 on the Regulatory Framework of Electric Energy, which must ensure the following bases: – The free international trade of electricity. – The free commercialization, competition and expansion of markets, and the possibility for end users to choose their supplier. – The explicit identification of the different concepts payable by end users. – The development of electricity transportation infrastructure through open, transparent, efficient and competitive mechanisms. – The review of the administrative structures of the electricity sector, modernizing and professionalizing them. The Law of Bases merges the gas and electricity regulators (ENRE and Enargas) into a single National Gas and Electricity Regulatory Entity, which will have the same functions. In this regard, on July 7, 2025, the Executive Branch issued Decree No. 452/2025, through which said entity was constituted. Foreign exchange market Since December 2019, the Central Bank of Argentina (BCRA) had issued a series of communications indefinitely extending foreign exchange regulations, which included controls on exports and imports, as well as the requirement for prior BCRA authorization to access the foreign exchange market for the remittance of profits and dividends abroad, among other restrictions. In particular, the refinancing of foreign financial debt under certain conditions was required. The effects of these regulations on the Group’s loans as of March 31, 2026, are described in Note 7.3.8. Following the inauguration of the new national government on December 10, 2023, restrictions on payments for imports cleared through customs as from December 13, 2023 were eased, although some of the BCRA-imposed restrictions on access to the Single and Free Exchange Market (MULC) and foreign exchange operations remained in place. Subsequently, on April 11, 2025, the national government implemented a set of measures aimed at easing the regulatory framework governing access to the MULC. These measures included: (i) the establishment of a band scheme for the determination of the exchange rate within which the U.S. dollar may fluctuate in the MULC; the initial band was set between 1,000 and 1,400 pesos, with its limits adjusted at a monthly rate of 1%; (ii) the elimination of the program that allowed the settlement of export proceeds using a split mechanism -37 - English translation of the consolidated financial statements originally filed in Spanish with the Argentine Securities Commission (“CNV”). In case of discrepancy, the consolidated financial statements filed with the CNV prevail over this translation CENTRAL PUERTO S.A. of 80% through the MULC and 20% through the financial market; (iii) the relaxation of access of individuals to the MULC for the purchase of foreign currency, subject to the requirements and conditions established by the BCRA, as well as the maintenance and/or adjustment of certain cross restrictions with securities transactions settled in foreign currency, whether directly or indirectly or on behalf of third parties, and the elimination of the tax surcharge applicable to the purchase of foreign currency in the MULC (while maintaining it for tourism and credit card payments); (iv) the authorization for Argentine companies to distribute dividends to foreign shareholders for fiscal years beginning in 2025; (v) a relaxation of payment terms for foreign trade transactions; and (vi) specific adjustments regarding certain restrictions on access to the MULC applicable to legal entities, in order to allow such entities to resume access to the MULC under normal conditions. As from January 1, 2026, the BCRA established that the upper and lower limits of the exchange rate band scheme will be adjusted monthly based on the most recently published inflation data, with the objective of mitigating episodes of excessive volatility in the foreign exchange market, while allowing the exchange rate to fluctuate within the bands according to market conditions. Income Tax On June 16, 2021, the Argentine Executive Branch enacted Law No. 27,630, which established changes in the corporate income tax rate for fiscal years commencing on or after January 1, 2021. This law establishes payment of the tax based on a structure of staggered rates depending on the level of accumulated taxable net income. The threshold amounts in this scale will be annually adjusted, considering the annual variation of the consumer price index provided by the INDEC corresponding to October of the year prior to the adjustment compared with the same month of the previous year. For fiscal year 2025 the applicable scale is the following: 25% up to an accumulated taxable net income of 101.7 million pesos, 30% for the excess of such amount up to 1,016.8 million pesos, and 35% for the excess of such amount. Meanwhile, for fiscal year 2026 the applicable scale is the following: 25% up to an accumulated taxable net income of 133.5 million pesos, 30% for the excess of such amount up to 1,335.1 million pesos, and 35% for the excess of such amount. Investment Promotion Plan In order to boost the productive structure while generating employment and fiscal resources, the national government has implemented during 2024 the “Large Investment Incentive Regime” (RIGI), established under the Law of Bases, which will grant tax benefits, access to foreign currency for imports, and, under certain conditions, allow the remittance of profits to investment projects submitted and approved in certain strategic sectors capable of generating exports in the medium and long term. 14. Restrictions on income distribution Pursuant to the General Companies Law and the Bylaws, 5% of the profits of the fiscal year must be assigned to the statutory reserve until such reserve reaches 20% of the Company’s Capital Stock. The profits distributed to individuals residing in Argentina or abroad, and to foreign legal entities, are subject to a withholding of 7% as a dividend tax, provided that such profits correspond to fiscal years closed after December 31, 2017. Pursuant to the General Companies Law and CNV regulations, since the disposal of treasury shares must be made with realized and liquid profits or free reserves, while such shares are held in treasury there is a -38 - English translation of the consolidated financial statements originally filed in Spanish with the Argentine Securities Commission (“CNV”). In case of discrepancy, the consolidated financial statements filed with the CNV prevail over this translation CENTRAL PUERTO S.A. restriction on the distribution of unappropriated retained earnings or free reserves for an amount equivalent to their cost. In addition, certain loan agreements establish requirements for the distribution of dividends (see Notes 7.3.1, 7.3.3, 7.3.4, 7.3.8 and 7.3.9). 15. Guarantees granted In guarantee of the performance of the obligations arising from the concession agreement of the Piedra del Águila Hydroelectric Complex entered into on January 9, 2026 (see Note 1.1), the Company has pledged in favor of the National State all Class “A” shares of PDAHA, representing 51% of the share capital of such company, for the entire 30-year concession term granted to PDAHA. On March 19, 2009, the Group entered into a pledge agreement with the Secretariat of Energy to secure its obligations in favor of the FONINVEMEM trusts under the operation and maintenance agreement of the Timbúes and Manuel Belgrano power plants, whereby it pledged 100% of the shares in TSM and TMB. Additionally, the shares acquired by the Group in Central Costanera S.A. are subject to a pledge, and the Group is carrying out the necessary procedures to cancel it. In turn, the Group has entered into exchange-traded collateral transactions (“cauciones bursátiles”), which are financial transactions secured by short-term negotiable securities denominated in local currency. In connection with the loan agreement described in Note 7.3.11, the Group has granted as collateral T-Bills, which are included within the balance of other non-current financial assets. Furthermore, the Group has granted guarantees for the performance of the agreements described in Notes 1.2.a) and 18.3 to the consolidated financial statements for the fiscal year ended December 31, 2025, already issued, and in Notes 7.3.1, 7.3.3 and 7.3.8. As of June 30, 2026 and December 31, 2025, the Group had delivered deferred payment checks to CAMMESA amounting to 17,430,400 and 2,450,425, respectively, as collateral for bid maintenance obligations related to the National and International Open Call “Almacenamiento AlmaSADI” and for the projects awarded under Resolution S.E. No. 67/2025 (see Note 1.2.r to the consolidated financial statements for the year ended December 31, 2025, already issued), respectively. 16.
