Earnings presentation 4Q25 and FY2O25

Buenos Aires, March Sth, Central Puerto S.A ("Central Puerto" or the "Company"} (NYSE: CEPU; BYMA: CEPU), the largest private power generation company in Argentina, reports its financial results for the fourth quarter 2025 ("4Q25"), ended on December 31**, 2025, and full year 2025.

A conference call to discuss the results of this quarter and full year will be held tomorrow, March 6*^ at 1O:OO AM ET Eastern Time (12:OO PM BAT). Webcast Access is available on our website.

Business development projects & events update

  • Piedra del Aguila concession extension to 2055: In December 2025, the Company was awarded the concession under the Comahue Hydroelectric Complex privatization process, extending the operating term of the Piedra del Aguila hydroelectric facility throug h 2055. Winning bid offer was US$ 245 MM, paid in January 2026.

  • San Carlos solar farm: The asset reached commercial operation {COD) in November 2025, adding 15 MW of renewable capacity to our portfolio. Together with Cafayate (acquired through M&A), our two 2025 solar projects doubled our installed solar capacity and increased our total renewable portfolio (wind and solar) by 20%.

  • Closing of Brigadier Lopez combined cycle of 420 MW: The asset achieved commercial operation date (COD) during 1Q26.

  • Maintenance update: Lujan de Cuyo LDCU TG26 (47 MW). In November 2025, after a comprehensive technical assessment with Siemens Energy, we decided to undertake a full stator replacement. While this represents an unplanned maintenance event, the selected scope will ensure long-term reliability and asset integrity. The unit is expected to return to service in the second half of 2026.

    Financial & operational highlights of the 4th quarter and full year 2025

  • 4Q25 Adjusted EBITDA was US$ 84.7 MM, 16% below the US$ 101.1 MM Adjusted EBITDA in 3Q25. FY25 Adjusted EBITDA was US$ 337.2 MM, 17% above FY24 Adjusted EBITDA of US$ 288.0 MM.

  • Total generation volumes in 4Q25 were 3,957 GWh, representing a 13% decrease compared to 3Q25 (4,539 GWh) and a 27% decline versus 4Q24 (5,416 GWh). Full year 2025 generation volumes were 18,598 GWh, a 14% decrease compared to 21,605 GWh of 2024. Lower annual volumes are explained mainly by lower hydrology at Piedra del Aguila (-38% y/y) and maintenance work in Central Costanera's combined cycles (-15% y/y) and Lujan de Cuyo cogeneration downtime in 4Q25 (-24% y/y).

  • Revenues from sales in 4Q25 totalized US$ 172.8 MM, which represented a 26% decrease q/q (US$ 233.9 MM in 3Q25). FY25 revenues from sales totalized US$ 782.6 MM, which represented a 17% increase y/y (FY24 revenues were US$ 671.3 MM). On an annual basis, from total revenues, energy sales represented 91%, and US$ 712.3 MM in 2025, a 20% increase compared to 2024 (FY24 energy sales of US$ 595.4 MM). Spot prices realignment marked the year-over-year variation, and the effect of FO cost passthrough to spot prices, partially offset by lower generation from Piedra del Aguila hydro complex due to low water inflows. Thermal PPA reflects Terminal 6 (San Lorenzo) self purchased liquids (Resol 21/2025), new MAT contracts in November and December 2025, and renewables reflect higher wind resources in 2025 vs 2024, which implied higher generation volumes and new solar capacity from the acquired Cafayate asset (80 MW incorporated in August 2025).

  • Capital Expenditures: In 2025, total capex reached US$ 202.4 million. This included US$

    48.5 million for the acquisition of the Cafayate solar farm, completed in Aug ust, as well

    as investments related to the completion of the Brigadier Lopez combined cycle plant and the San Carlos solar project-both initiated in 2024-along with maintenance capex composed of recurrent maintenance capex (US$ 25 MM) and non-recurrent from Central Costanera and Lujan de Cuyo (US$ 27 MM).

  • As of December 31, 2025, total outstanding gross debt balance was US$ 337.8 MM, and net financial debt resulted in US$ 106.3 MM and net leverage ratio was 0.32 x Adj. EBITDA.

  • Outstanding credit from Foninvemem program stood at US$ 118.6 MM, to continue being collected in monthly installments throug h May 2028.

  • The Company signed on Dec. 19, 2025, a US$ 3OO MM A/B syndicated loan with International Finance Corporation (IFC), with an average life of approximately five years. The credit line was granted to finance the privatization fee of Piedra del Aguila and the battery energy system storage (BESS) project.

Resolution SE 400/25: Wholesale Electricity Market reform initiated - transition explained

In October 2025, the generation units without PPAs-mainly Central Puerto and Central Costanera-continued to be remunerated under Energy Secretariat Resolution No. 381/25.

Effective November 1, 2025, these thermal units transitioned to the framework established by Resolution No. 400/25, marking a further step toward Wholesale Electricity Market (WEM) normalization. The new scheme introduced two revenue streams:

  1. a marg inalist spot market remuneration for dispatched energy, and

  2. the Term Market (MAT), through which capacity and energy may be contracted with large users and distributors.

    As part of this ramp-up toward contractualization, during November and December 2025 Central Puerto delivered approximately 900 MWh under new TERM contracts with industrial customers, representing around 11% of total new TERM volumes executed in the market during that period.

    Under Resolution No. 400/25, the 4Q25 spot remuneration scheme for thermal assets consisted

    of:

    • Energy component: Spot price formula based on CVP + RMA, equivalent to approximately US$ 7/MWh net of fuel costs.

    • Capacity payment: US$ 12 per MW-month with a remunerated availability of 90 hours per week. Fuel-related factors: Natural gas (single-fuel units): 1.1 (summer/winter) and

      0.9 (shoulder months). Alternative fuels (FO, GO): 1.5 (summer/winter) and 1.O (shoulder months).

    • Reliability reserve component: Additional remuneration of US$ 1,OOO per MW-month for assets previously categorized as spot thermal units.

      Meanwhile, the hydro plant Piedra del Aguila remained under its prior regulatory framework during the quarter. However, it was reached by Resolutions No. 483/25 and No. 602/25, applicable to November and December 2025, respectively.

      Additionally, the Gas and Steam Turbine (GT/ST) units at Central Puerto and Central Costanera that adhered to Resolution No. 294/2024-within the Contingency and Forecast Plan for the 2O24-2O26 critical period-continued receiving incremental remuneration of US$ 2,500 per MW (which will be applicable throug h March 2027). This scheme aims to ensure system reliability during peak demand and critical supply conditions.

      A. 2025 Electricity market summary Annual demand for electricity

      • In 2025, the system reached a historic peak capacity of 30,257 MW on February 10, surpassing the previous record.

      • Renewable generation increased 16.5% year-over-year, supplying approximately 19% of total demand.

      • Including hydroelectric generation, total renewable participation represented approximately 38.6% of the annual energy mix.

E. Revenues

Revenues from sales in 4Q25 totalized US$ 172.8 MM, which represented a 26% decrease q/q (US$ 233.9 MM in 3Q25). FY25 revenues from sales totalized US$ 782.6 MM, which represented a 17% increase y/y (FY24 revenues were US$ 671.3 MM). On an annual basis, from total revenues, energy sales represented 91%, and US$ 712.3 MM in 2025, a 20% increase compared to 2024 (FY24 energy sales of US$ 595.4 MM). Spot prices realignment marked the year-over-year variation, and the effect of FO cost passthroug h to spot prices, partially offset by lower generation from Piedra del Aguila hydro complex due to low water inflows. Thermal PPA reflects new MAT contracts in November and December 2025, and renewables reflect higher wind resources in 2025 vs 2024, which implied higher generation volumes and new solar capacity from the acquired Cafayate asset (80 MW incorporated in Aug ust 2025).

    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 (https://www.sec.qov) and CNV.

    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.
