BUENOS AIRES, AR / ACCESS Newswire / May 6, 2026 / Pampa Energía S.A. (NYSE:PAM)(Buenos Aires Stock Exchange:PAMP), an independent energy company with active participation in Argentine oil, gas and electricity, announces the results for the quarter ended on March 31, 2026.

Pampa reports its financial information in US$, its functional currency. For local currency equivalents, transactional exchange rate (‘FX') is applied. However, Transener and Transportadora de Gas del Sur's (‘TGS') figures are adjusted for inflation as of March 31, 2026, and converted to US$ using the period-end FX. Previously reported figures remained unchanged.

First quarter 2026 (‘Q1 26') main results[¹]

Sales reached US$573 million in Q1 26^[2], up 38% year-on-year, driven primarily by higher shale oil production at Rincón de Aranda and the Wholesale Electricity Market's (‘WEM') new power generation framework, which led to stronger spot prices and increased gas sales to our thermal power plants. Lower crude oil prices and volumes sold under the Plan Gas Gas Sale Agreements (‘GSA') partially offset these effects.

The Q1 26 reflected sustained expansion in shale oil production at Rincón de Aranda, together with higher gas sales, supported by the vertical integration with the power generation business.

Note: * Price net of export duty and quality/logistic discounts.

Adjusted EBITDA[³] totaled US$325 million in Q1 26, a 48% year-on-year increase, reflecting higher shale oil contributions, stronger spot margins in power generation, and growth in gas sales, offset by lower realized crude oil prices due to hedging.

Net income attributable to shareholders was US$214 million, 40% higher than Q1 26, driven by stronger operating margins and a higher recognition of a non-cash deferred income tax credit, as inflation outpaced the AR$ devaluation. These effects were partially offset by the recovery of a customs contingency recorded in Q1 25.

Net debt stood at US$1.2 billion as of March 2026, vs. US$801 million as of December 2025, reflecting higher capital expenditures and increased collateral requirements due to oil hedging.
