Highlights of the quarter 2Q25 Adjusted EBITDA was US$ 61.4 MM, a -32% compared to the US$ 89.9 MM Adjusted EBITDA in 1Q25, and +35% compared to 2Q24 Adjusted EBITDA of US$ 45.6 Total generation volumes in 2Q25 reached 4,372 GWh, representing a 24% decrease compared to 1Q25 (5,731 GWh) and a 12% decline versus 2Q24 (4,985 GWh). Lower volumes are explained mainIy by the maintenance work at the Mitsubishi combined cycle of Central Costanera which generated 409 GWh in 2Q25, 75% below from 1Q25 (1,612 GWh) and 57% lower than 2Q24 (961 GWh) and the maintenance of the STO6 (TVO6) of Central Puerto complex which generated 5.3 GWh in 2Q25 vs 191.8 GWh in 1Q25 and 90.3 GWh in 2Q24. Revenues in 2Q25 totalized US$ 179.6 MM, which represented an 8% decrease compared to 1Q25 (US$ 196.2 MM) and an increase of 7% compared to 2Q24 (US$ 168.3 MM). Revenues from energy sales represented 89.6% out of total revenues.

Although the resolution was issued at the end of January, the self-managed fuel procurement scheme was established to begin in March 2025. As a result, its full impact was reflected in the current quarter, which we will discuss in more detail in the following sections. Electricity market balance and trends The total system installed capacity remained stable both quarter-over-quarter and year-over-hear, with a 3% increase in renewable capacity compared to the previous quarter. The 11% year-on-year decrease in hydro capacity (from Yacireta's bi-national plant generation reassignment agreement) was offset by a 21% increase in renewables. Offer: Thermal generation decreased 24.5% q/q while hyd ro generation increased 14.9% q/q. Demand: Electricity demand declined by 12% in 2Q25 compared to 1Q25, primarily due to milder temperatures. This resulted in lower energy consumption from the residential (-15.7% q/q) and commercial (-13.7% q/q) segments-a seasonal trend typically expected in the autumn months compared to summer.

Accordingly, the financial statements have been stated in terms of the measuring unit current at the end of the reporting period, including the corresponding financial figures for previous periods reported for comparative purposes. Comparative analysis refers to the same period of the previous year, measured in the current unit at the end of the period, unless otherwise stated. Consequently, the information included in the Financial Statements for the second quarter ended on June 3O th , 2025, is not comparable to the Financial Statements previously published by the company. However, we presented some figures converted from Argentine Pesos to U.S. dollars for comparison purposes only. The exchange rate used to convert Argentine Pesos to U.S. dollars was the reference exchange rate (Communication "A" 3500) reported by the Central Bank for U.S. dollars for the end of each period. The information presented in U.S. dollars is for the convenience of the reader only and may defer if such conversion for each period is performed at the exchange rate applicable at the end of the latest period. You should not consider these translations to be representations that the Argentine Peso amounts actually represent these U.S. dollars amounts or could be converted into U.S. dollars at the rate indicated. Definitions and terms used herein are provided in the Glossary at the end of this document. This release does not contain all the Company's financial information. As a result, investors should read this release in conjunction with Central Puerto's Audited Consolidated Financial Statements for the fiscal period ended on December 31st, 2O24, and the notes thereto, which will be available on the Company's website. Roundinq amounts and percentages: Certain amounts and percentages included in this release have been rounded for ease of presentation. Percentage figures included in this release have not in all cases been calculated on the basis of such rounded figures, but on the basis of such amounts prior to rounding. For this reason, certain percentage amounts in this release may vary from those obtained by performing the same calculations using the figures in the financial statements. In addition, certain other amounts that appear in this release may not sum due to rounding. This release contains certain metrics, including information per share, operating information, and others, which do not have standardized meanings or standard methods of calculation and therefore such measures may not be comparable to similar measures used by other companies. Such metrics have been included herein to provide readers with additional measures to evaluate the Company's performance; however, such measures are not reliable indicators of the future performance of the Company and future performance may not compare to the performance in previous periods. OTHER INFORMATION Central Puerto routinely posts important information for investors in the Investor Relations support section on its website, www centralouerto com. From time to time, Central Puerto may use its website as a channel of distribution of material Company information. Accordingly, investors should monitor Central Puerto's Investor Relations website, in addition to following the Company's press releases, SEC filings, public conference calls and webcasts. The information contained on, or that may be accessed through, the Company's website is not incorporated by reference into, and is not a part of, this release. CAUTIONARY STATEMENTS RELEVANT TO FORWARD-LOOKING INFORMATION This release contains certain forward-looking information and forward-looking statements as defined in applicable securities laws (collectively referred to in this Earnings Release as "forward-looking statements") that constitute forward-looking statements. All statements other than statements of historical fact are forward-looking statements. The words "anticipate", "believe", "could", "expect", "should", "plan", "intend", "will", "estimate" and "potential", and similar expressions, as they relate to the Company, are intended to identify forward-looking statements. Statements regarding possible or assumed future results of operations, business strategies, financing plans, competitive position, industry environment, potential growth opportunities, the effects of future regulation and the effects of competition, expected power generation and Cenkr»l RueNo capital expenditures plan, are examples of forward-looking statements. Forward-looking statements are necessarily based upon a number of factors and assumptions that, while considered reasonable by management, are inherently subject to significant business, economic and competitive uncertainties, and contingencies, which may cause the actual results, performance, or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. The Company assumes no obligation to update forward-looking statements except as required under securities laws. Further information concerning risks and uncertainties associated with these forward-looking statements and the Company's business can be found in the Company's public disclosures filed on EDGAR (www sec gov ). EBITDA and Adjusted EBITDA In this release, EBITDA, a non-IFRS financial measure, is defined as net income for the period, plus finance expenses, minus finance income, minus share of the profit (loss) of associates, plus minus) losses (gains) on net monetary position, plus income tax expense, plus depreciation and amortization, minus net results of discontinued operations. Adjusted EBITDA refers to EBITDA excluding impairment on property, plant & equipment, foreign exchange differences and interests related to FONI trade receivables and variations in fair value of biological asset. Adjusted EBITDA is believed to provide useful supplemental information to investors about the Company and its results. Adjusted EBITDA is among the measures used by the Company's management team to evaluate the financial and operating performance and make day-to-day financial and operating decisions. In addition, Adjusted EBITDA is frequently used by securities analysts, investors, and other parties to evaluate companies in the industry. Adjusted EBITDA is believed to be helpful to investors because it provides additional information about trends in the core operating performance prior to considering the impact of capital structure, depreciation, amortization, and taxation on the results. Adjusted EBITDA should not be considered in isolation or as a substitute for other measures of financial performance reported in accordance with IFRS. Adjusted EBITDA has limitations as an analytical tool, including: Adjusted EBITDA does not reflect changes in, including cash requirements for, working capital needs or contractual commitments. Adjusted EBITDA does not reflect the finance expenses, or the cash requirements to service interest or principal payments on indebtedness, or interest income or other finance income. Adjusted EBITDA does not reflect income tax expense or the cash requirements to pay income taxes. Although depreciation and amortization are non-cash charges, the assets being depreciated or amortized often will need to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for these replacements. Although a certain share of the profit of associates is a non-cash charge, Adjusted EBITDA does not consider the potential collection of dividends; and Other companies may calculate Adjusted EBITDA differently, limiting its usefulness as a comparative measure. The Company compensates for the inherent limitations associated with using Adjusted EBITDA through disclosure of these limitations, presentation of the Company's consolidated financial statements in accordance with IFRS and reconciliation of Adjusted EBITDA to the most directly comparable IFRS measure, net income. For a reconciliation of the net income to Adjusted EBITDA, see the tables included in this release. All the information presented must be considered as consolidated unless otherwise specified.
