Business Context and Reporting Period
Company: Central Puerto S.A. (NYSE/BYMA: CEPU), the largest private power generation company in Argentina.
Reporting Period: Third Quarter 2025 (ended September 30, 2025).
Filing Date: November 12, 2025.
Key Context: The quarter was marked by the implementation of Resolution SE 400/2025, a significant reform liberalizing Argentina's Wholesale Electricity Market effective November 1, 2025. This reform introduces a new Thermal Term Market (MAT) and shifts remuneration toward US$-denominated spot prices to mitigate inflation and currency risk.

Material Changes vs. Prior Periods
- Revenue Growth: Total revenues increased 30% quarter-over-quarter (q/q) and 26% year-over-year (y/y). Energy sales specifically rose 34% q/q and 31% y/y, driven by higher spot volumes from Central Costanera (post-maintenance) and increased fuel cost pass-throughs.
- EBITDA Expansion: Adjusted EBITDA surged 64% q/q to US$ 101.1 MM, primarily due to higher operating income from thermal assets and a 24% increase in renewable revenues.
- Generation Volumes: Total generation was 4,539 GWh, up 4% q/q but down 20% y/y. The y/y decline was driven by significantly lower hydrology at Piedra del Águila (-59% y/y), partially offset by higher wind generation and the new Cafayate solar farm.
- Margin Improvement: Thermal & Hydro operating margin improved to 26% (US$ 47.7 MM) from 8% in 2Q25, while Renewable margins reached 57%.
Guidance, Outlook, and Management Commentary
Regulatory & Market Outlook
Management highlights the new Resolution SE 400/2025 as a catalyst for long-term value creation. Key features include:
- Market Flexibility: Thermal generators can now trade up to 20% of production with Large Users and 100% with Distributors in the new Term Market.
- US$ Denomination: Spot remuneration and capacity payments are increasingly US$-denominated, reducing FX risk.
- Capacity Payments: New spot market capacity payments of US$12/MW-month and reliability reserves of US$1,000/MW-month (US$9,000/MW-month for new assets).
Operational & Capital Plans
- Acquisitions: Completed acquisition of the 80 MW Cafayate solar farm for US$ 48.5 MM (PPA through 2039).
- BESS Projects: Secured contracts for two Battery Energy Storage System projects (205 MW total) in the AlmaGBA tender with 15-year fixed US$ contracts. Estimated capex: US$ 130-140 MM.
- 4Q25 Maintenance: Scheduled maintenance at Luján de Cuyo (45 days) and Central Costanera (60 days) to extend asset life.
- Debt Management: Repaid US$ 90 MM in debt in October 2025 (Class A bond and Guañizuil solar debt). Issued US$ 89 MM in Class "C" Corporate Bonds in August 2025.
- Share Buyback: Initiated a US$ 20.0 MM buyback program; repurchased 2.76 MM shares for US$ 2.54 MM to date.
Risks and Contingencies
- Hydrology: Continued reliance on hydrology at Piedra del Águila remains a volatility factor.
- Regulatory Transition: Successful navigation of the transition to the new market model (Resolution 400) and fuel management responsibilities starting 2029.
- FX & Inflation: Financial statements are adjusted for inflation (IAS 29); mismatches between inflation and currency depreciation can create non-cash accounting effects.
Investor Verification Checklist
- Hydrology Impact: Verify the sustainability of hydro generation volumes at Piedra del Águila given the -59% y/y decline.
- Regulatory Implementation: Monitor the practical application of Resolution SE 400/2025 and the actual realization of US$-denominated spot revenues.
- Debt Maturity Profile: Review the maturity schedule of the US$ 452.1 MM gross debt, particularly the impact of the new Class "C" bond issuance.
- Capex Execution: Track the execution and cost overruns of the US$ 130-140 MM BESS projects and the San Carlos solar project.
- Non-Cash Adjustments: Scrutinize the "Gain on net monetary position" line item to understand the divergence between Net Income and cash flow generation.
