1. Relevant events

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.1** **Urea Project: application to RIGI** 

On April 21, 2026, Fértil Pampa S.A.U., a wholly-owned subsidiary of Pampa, filed the application to adhere to the RIGI for the construction, operation, and management of a complex located in Bahía Blanca. The facility is designed to produce granular urea, ammonia, and other fertilizers.

The project, currently in the final stage of feasibility assessment, aligns with our strategy to integrate and monetize our natural gas resources by expanding their use toward higher-value-added products. The urea plant is expected to receive gas from our Neuquina Basin blocks and to reach an annual production capacity of 2.1 million tons starting in 2030. The estimated investment amounts to approximately US$2.4 billion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.2** **Oil and gas** 

***Rincón de Aranda: application to RIGI***

On March 9, 2026, under the RIGI framework for greenfield hydrocarbon projects (DNU No. 105/26), Pampa applied to include the development of Rincón de Aranda as a strategic long-term export project. The initiative enables the development of the northern area of Rincón de Aranda, accelerating production ramp-up, reaching the plateau more quickly, and sustaining it for a longer period. The application contemplates the development of new shale oil wells and the construction of associated infrastructure, with an estimated investment of US$4.5 billion.

***SESA: San Matías Pipeline Project***

San Matías Pipeline S.A. was incorporated, with Pampa holding a 20% equity interest to support the FLNG project led by SESA, which includes the chartering and mooring of two liquefaction vessels in San Matías Gulf. The company will be responsible for the construction and operation of the dedicated gas pipeline to transport gas from Neuquina Basin to San Matías Gulf, in Río Negro, supplying the liquefaction units. The pipeline is expected to have a 36-inch diameter, approximately 470 km in length, and reach a transportation capacity of up to 28 mcmpd.

***Pass-through of Plan Gas contracts with ENARSA***

On March 5, 2026, the SE extended by an additional 180 days the deadline for producers to reassign Plan Gas GSAs with ENARSA to distribution companies and CAMMESA (Res. SE No. 54/26). Distributors must adhere within the same timeframe. ENARGAS, together with ENARSA, will define and oversee the implementation process and volume allocation.

***Changes in the energy subsidies scheme***

On March 2, 2026, ENARGAS defined the new Targeted Energy Subsidies regime, which replaces the income-based segmentation scheme in force since 2022 with a simplified binary system, effective February 2026 (Res. ENARGAS No. 101/26 and DNU No. 943/25).

Under the new scheme, eligible households receive a 50% discount on electricity costs, applicable to up to 300 kWh of monthly consumption between December and February (summer) and up to 150 kWh for the rest of the year. For gas, the 50% discount applies to baseline consumption from April to September, the peak-demand period.

In addition, eligibility criteria were redefined. Only households with declared net income at or lower than three INDEC basic baskets qualify. The regime maintains the existing mechanism for natural gas producers, who continue to receive compensation, deducted from distributors' billing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.3** **Generation** 

***Award of capacity in the GPM expansion and final sections***

As part of the expansions of the GPM and final sections to the Buenos Aires Metro Area for 12 mcmpd, on April 15, TGS awarded the tender's first tranche, corresponding to 40% of said incremental capacity. The awarded shippers will execute 35-year take-or-pay agreements, beginning with the expansion's commissioning, expected in winter 2027 and a tariff prepayment over the first 15 years, payable in four installments, with final maturity in April 2027.

Within this tender, Pampa was awarded 3.2 mcmpd, representing 27% of the additional capacity allocated to the Buenos Aires metro area. The associated prepayment amounts to approximately US$330 million. Participation in this gas pipeline expansion is underpinned by a clear economic rationale. Under the new WEM framework established by Res. SE No. 400/25, electricity generated using gas transported through new infrastructure —such as the GPM/final sections expansion— captures the full dispatch margin when sold in the spot market (FRA = 1). In addition to securing additional natural gas supply from our upstream operations, this framework enhances the profitability of our generation assets, particularly our CCGTs.

On June 3, 2026, TGS will receive the shippers' requests for the tender's second tranche, corresponding to the remaining 7.2 mcmpd, with gas distribution companies given priority.

***Bidding process for battery storage - AlmaSADI***

The SE launched an open national and international call for bids for electricity storage projects based on Battery Energy Storage Systems (BESS) (Res. SE No. 50/26). The process contemplates the award of up to 700 MW of capacity, distributed across regions and nodes defined by CAMMESA.

Awarded projects will enter into PPAs with CAMMESA for up to 15 years. The fixed remuneration for available storage capacity will be determined by the generator's bid price, capped at US$12,500/MW-month, plus a variable remuneration for energy delivered when required by CAMMESA, at US$10/MWh until 2037 and thereafter the spot price. In addition, the PPAs include a US$20/MWh consumption charge, calculated as the difference between the energy demanded and the energy delivered, as well as penalties for unavailability.

Bids are due on May 27, 2026, with awards expected on July 8. Pampa is assessing its participation in the tender.

***Expiration of HINISA's concession***

On April 15, 2026, the Province of Mendoza, in the context of preparing the tender documents for the new concession and to provide certainty to potential bidders, requested HINISA to assign the insurance receivables related to the January 2025 incident to Hidroelectricidad Mendocina S.A., the future owner of HINISA's assets. The transfer of the insurance rights referred to the damage was approved on April 22, 2026.

***Changes in the natural gas transportation system***

On January 26, 2026, the National Government extended the emergency for the natural gas transportation and distribution segments through December 31, 2027 (DNU No. 49/26). Within this framework, the SE terminated ENARSA's firm gas transportation contracts with CAMMESA and TGS, discontinued the Transport.Ar Domestic Production program (Res. SE No. 67/22), and repealed the exceptional export regime established by DNU No. 689/02.

In addition, a new remuneration scheme for gas transportation was introduced to better reflect underlying system costs and promote private investment in infrastructure, while maintaining the regulatory income set in the five-year tariff review (RQT). The new framework incorporates capacity reallocation, updated contractual terms and regulations, and revised tariff schedules aligned with the new system. On April 14, 2026, ENARGAS completed the reorganization process, with an initial impact on TGS's monthly revenues broadly neutral (Res. ENARGAS No. 409/26).

***Expansion of the power transmission grid through public work concessions***

On April 7, 2026, the SE introduced changes applicable to the regulatory framework for expanding the power transmission grid through public works concessions, incorporating the associated receivables into the WEM payment system.

The new framework applies exclusively to expansions previously designated by the PEN under Law No. 17,520. The works will be awarded through public tenders, although they may be promoted through private initiative (Res. No. 83/26).

The remuneration scheme will be defined in the tender documents and will include remuneration to repay the investment, and an operation and maintenance fee set by the ENRE, pursuant to the independent transmission regime. Such remuneration may be financed through charges to WEM beneficiary users, subject to ENRE's review, public hearings and final approval by the SE.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.5** **Annual Shareholders' Meeting: Board changes and share cancellation** 

On April 7, 2026, Pampa's Shareholders approved the re-election of Gustavo Mariani and Ricardo Alejandro Torres as directors, and María Agustina Montes and Horacio Jorge Tomás Turri as alternate directors, all in executive roles. Additionally, the Shareholders' Meeting approved the appointment of Nicolás Aguzín as an independent director, replacing Silvana Wasersztrom. All terms will run for three fiscal years, until December 31, 2028.

Furthermore, the Assembly approved the cancellation of 19.9 million shares (equivalent to 0.8 million ADRs), effective April 22, 2026. As of today, Pampa's outstanding share capital amounts to 1,343,600,101 ordinary shares, equivalent to 53,744,004 ADRs.

**Sales** in the oil and gas segment rose 69% year-on-year, driven by the ramp-up in crude oil production at Rincón de Aranda and increased gas sales to Chile, industries and our CCGTs under the new WEM normalization guidelines, which, since November 2025, allow thermal units without PPAs with CAMMESA to procure their own fuel. Lower sales under the Plan Gas GSA, particularly with CAMMESA, due to the pass-through of contracts, and lower realized crude oil and gas export prices partially offset said effects.

Regarding **operational performance**, total production reached a quarterly record high of 100.6 kboepd in Q1 26, +38% vs. Q1 25, driven by higher shale oil output at Rincón de Aranda and increased gas demand for self-supply at CTLL and CTGEBA, which are highly dispatched CCGTs. Compared to Q4 25, the 24% increase in production was driven by gas self-supply for power generation, which began in December 2025.

**Gas production** was 13.8 mcmpd (+17% vs. Q1 25, +28% vs. Q4 25). Operated blocks El Mangrullo and Sierra Chata accounted for 88% of total production, each contributing 6.1 mcmpd. At El Mangrullo, production dropped 7% vs. Q1 25 but grew 22% sequentially, driven by higher demand without new wells tied in since July 2025. Sierra Chata production increased by 70% vs. Q1 25 and 50% vs. Q4 25, driven by 4 new wells brought online during Q4 25. Associated gas from Rincón de Aranda contributed 0.1 mcmpd<br> (-27% vs. Q4 25).

In non-operated areas, Río Neuquén produced 1.2 mcmpd (-18% vs. Q1 25, +5% vs. Q4 25), while 0.3 mcmpd was jointly contributed by Rincón del Mangrullo (-16% vs. Q1 25, -8% vs. Q4 25) and Aguaragüe (-20% vs. Q1 25, + 2% vs. Q4 25), both continuing their natural decline.

**Note:** Net production in Argentina. Gas volume standardized at 9,300 kCal. Oil price is net of export duty and quality/logistic discounts. Production as of March 2025 includes 1.3 kbpd of crude produced at El Tordillo and La Tapera-Puesto Quiroga, blocks transferred to Crown Point Energía S.A. in October 2025.

The **gas price** averaged US$2.9 per MBTU in Q1 26, -4% vs. Q1 25, due to lower export prices, partially offset by higher prices to retail demand, where tariff adjustments outpaced the AR$ devaluation. Prices remained broadly stable compared to Q4 25, reflecting similar seasonal conditions.

Regarding **gas deliveries by customer type**, during Q1 26, 24% of gas sales were allocated to thermal dispatch for CAMMESA (vs. 61% in Q1 25) and 23% to retail distributors (flat vs. Q1 25). Together, these segments accounted for 47% of volume sold under the Plan Gas, significantly reduced by the pass-through of GSAs to our power plants. As a result, intercompany consumption increased significantly to 32% of total sales (vs. 2% in Q1 25), mainly driven by fuel self-procurement for generation at CTLL and CTGEBA, and, to a lesser extent, by our petrochemical operations. The remaining 21% was split between the industrial/spot market (10% vs. 8% in Q1 25) and exports (11% vs. 8% in Q1 25).

**Oil production** reached 19.5 kbpd in Q1 26 (6x vs. Q1 25, +8% vs. Q4 25), driven by the acceleration at Rincón de Aranda, which averaged 18.2 kbpd in Q1 26 (+17.4 kbpd vs. Q1 25, +7% vs. Q4 25), supported by 43 producing wells (vs. 6 in Q1 25 and 28 in Q4 25). The divestments at El Tordillo and La Tapera-Puesto Quiroga in October 2025 partially offset these effects (-1.3 kbpd vs. Q1 25).

The average **oil price**, net of export duty and commercial discounts, averaged US$58.2 per barrel (-15% vs. Q1 25, -4% vs. Q4 25), impacted by the Brent hedge over Rincón de Aranda's production. Without the hedge, the realized price would have been US$69.5 per barrel, resulting in approximately US$21 million of additional revenue. Exports accounted for 55% of total volume sold in Q1 26 (29% in Q1 25 and 48% in Q4 25).

The **lifting cost<sup>4</sup>** totaled US$56 million in Q1 26, +23% vs. Q1 25, explained by higher treatment costs, the expansion of temporary facilities at Rincón de Aranda and increased gas conditioning costs. These increases were partially offset by lower maintenance and labor costs, following the divestment in non-operated conventional oil assets. Quarter-on-quarter, the 7% improvement in costs reflects the divestments mentioned earlier and, to a lesser extent, stable treatment costs. The **lifting cost per boe** decreased to US$6.1/boe produced (-11% vs. Q1 25 and -23% vs. Q4 25), as a result of the growth in Rincón de Aranda's production and increasing vertical integration with the power generation business.

Excluding depreciation, amortization, and lifting costs, **other operating costs** totaled US$78 million (+33% vs. Q1 25, +28% vs. Q4 25), mainly due to higher royalties and transportation costs linked to increased production levels.

------

<sup>4</sup> It only considers maintenance, treatment, internal transportation, wellhead staff and the TPF rental costs at Rincón de Aranda, which under IFRS it is recorded as Leases, accruing amortization on rights-of-use in the cost of sales. Lifting cost does not include amortizations and depreciations.

<br> Earnings Release Q1 26 ● 7

![](pampr1q266k_001.jpg)

**Other operating income and expenses** decreased by US$2 million vs. Q1 25, explained by lower income from Plan Gas compensation net of royalties, as retail prices are catching up to the GSA price following the tariff adjustments. Compared to Q4 25, it also decreased by US$2 million, due to lower income from Plan Gas compensation, partially offset by lower environmental provisions.

**Financial results** in Q1 26 improved to a net loss of US$15 million (-48% vs. Q1 25, -56% vs. Q4 25), as a slower pace of devaluation reduced FX losses on the segment's net monetary asset position in AR$.

Our oil and gas **adjusted EBITDA** amounted to US$104 million in Q1 26, +155% vs. Q1 25, mainly driven by the shale oil ramp-up production at Rincón de Aranda, higher gas sales resulting from gradual vertical integration with power generation, and growth in exports and industrial sales. These effects were partially offset by lower realized oil prices and higher royalties, transport and treatment costs, particularly from crude oil, associated with increased production. The 36% quarter-on-quarter increase is attributable to higher gas exports, self-procurement for power generation and, to a lesser extent, Rincón de Aranda's production. The adjusted EBITDA excludes extraordinary and non-cash income and expenses, overdue commercial interests, and equity income from affiliates, and includes a US$5 million reclassification to lifting costs on the TPF lease at Rincón de Aranda, which under IFRS is recognized as a capital expenditure.

**Capital expenditures** amounted to US$196 million (+33% vs. Q1 25, but -39% vs. Q4 25), with 83% allocated to the development of Rincón de Aranda.

In Q1 26, power generation **sales** grew 43% year-on-year, driven by higher spot remuneration for our thermal units following the implementation of the new WEM framework in November 2025. This increase was partially offset by lower fuel recognition due to the reassignment of the Plan Gas GSAs and by the outage of CTLL's GT04, sold under a PPA, since mid-January 2026. Compared to Q4 25, sales increased 35% due to higher spot energy prices and greater B2B sales in the MAT from CTLL, HINISA and CTGEBA.

Within the spot segment, capacity payments for CCGTs decreased to US$5.4 thousand per MW-month (-8% vs. Q1 25, but +21% vs. Q4 25). Moreover, GT and ST peakers averaged US$7.6 thousand per MW-month (+8% vs. Q1 25, +30% vs. Q4 25), supported by higher income at CPB, driven by its ability to operate on alternative fuels. Hydros averaged US$2.3 thousand per MW-month (-3% vs. Q1 25, +10% vs. Q4 25).

Regarding **operational performance**, operated power generation decreased slightly by 4% year-on-year, in line with the national grid's performance. Lower generation is explained by decreased hydro output, the continued outage at HINISA (-168 GWh), lower dispatch at CTG (-88 GWh), programmed maintenance at CTEB (-82 GWh), and the CTLL's GT04 outage mentioned earlier (-64 GWh). These effects were partially offset by higher thermal demand at CPB (+187 GWh) and CTIW (+29 GWh). Compared with Q4 25, dispatch rose 16%, driven mainly by CTGEBA and CPB.

The average **availability** of Pampa's operated units reached 89.9% in Q1 26 vs. 93.4% in Q1 25 (-350 basis points), reflecting forced outages at HINISA and CTLL's GT04 since January 2026, as well as the programmed overhaul at CTEB. Thermal availability dropped 468 basis points to 91.1% in Q1 26. In Q4 25, total and thermal availability stood at 91.3% and 93.2%, respectively.

**Note:** Gross margin before amortization and depreciation. It includes CTEB (co-operated by Pampa, 50% equity stake).

Excluding depreciation and amortization, **operating costs** increased 75% year-on-year to US$147 million in Q1 26, mainly due to higher gas purchases from our E&P to supply our thermal power plants and, to a lesser extent, increased maintenance costs. Lower labor, transportation, materials, and insurance expenses partially offset these effects. Compared to Q4 25, operating costs increased 29% due to higher gas purchases for self-procurement, partially offset by lower labor, materials and insurance costs.

**Other net operating income and expenses** posted US$1 million loss vs. US$5 million profit in Q1 25, driven by lower insurance recoveries net of repair costs.

**Financial results** in Q1 26 recorded a net profit of US$15 million, -40% vs. Q1 25, explained by lower income from holding financial assets, partially offset by FX gains from a softer AR$ devaluation, which impacted the net monetary asset position in that currency.

The **adjusted EBITDA** for the petrochemicals segment was breakeven in Q1 26, compared to a US$4 million loss in Q1 25, driven by higher margins at the Reformer, supported by a wider spread over local virgin naphtha prices, and lower operating expenses. These effects were partially offset by the US$2 million extraordinary gain recorded in Q1 25 from export settlements at a differential FX. Compared to Q4 25, adjusted EBITDA posted a slight decline due to higher idle capacity.

Total **volume** sold reached 83 thousand tons, slightly below the 84 thousand tons in Q1 25, due to lower sales of octane base and naphtha exports and, to a lesser extent, weaker SBR domestic demand. These effects were partially offset by higher styrene and polystyrene demand, as well as increased SBR and solvent exports. The 35% quarter-on-quarter reduction is attributable to the 35-day programmed overhaul at the Reformer during Q1 26.

**Financial results** recorded a net loss of US$9 million (-US$35 million vs. Q1 25 and -US$8 million vs. Q4 25), due to the interest recovery recorded in Q1 25 related to customs contingencies. In addition, higher losses from gasoline price hedging were recorded, driven by rising reference prices in March 2026, and, to a lesser extent, FX losses resulting from a softer AR$ devaluation over the net monetary liability position in that currency.

In the holding, transport and others segment, excluding equity income from affiliates, **operating margin** recorded a loss of US$5 million in Q1 26, -62% vs. Q1 25 and -75% vs. Q4 25. Lower provisions for contingencies and higher fee income mainly explain the improvement.

**Financial results** in Q1 26 recorded a US$19 million net loss (-US$26 million vs. Q1 25, -US$25 million vs. Q4 25), due to FX losses resulting from a softer AR$ devaluation, which impacted the net monetary liability position in that currency.

The **adjusted EBITDA** for the segment, which excludes non-operating, non-recurring, and non-cash items and includes EBITDA adjusted for equity ownership in TGS and Transener, reached US$77 million profit in Q1 26 (+45% vs. Q1 25, +85% vs. Q4 25), mainly driven by the strong performance of TGS and Transener and, to a lesser extent, by lower contingency provisions following the expiration of OCP Ecuador's concession.

At **TGS**, the EBITDA adjusted for our stake was US$60 million in Q1 26, +31% vs. Q1 25, mainly explained by higher processed volumes of NGLs, resulting from the recovery of the March 2025 extraordinary climate event in Cerri, together with a stronger contribution from the midstream business following the commissioning of the gas conditioning plant and higher take-or-pay sales. The regulated segment also showed a solid performance in US$ terms, supported by an accumulated 8% tariff increase in Q1 26, in line with inflation (9%) and benefiting from the softer AR$ devaluation.

At **Transener**, the EBITDA adjusted for our stake reached US$23 million vs. US$13 million in Q1 25, driven by a 7% accumulated tariff increase, although slightly below inflation (9%), it translated into stronger US$ results due to the softer AR$ devaluation.

As of March 31, 2026, Pampa's financial debt under IFRS totaled US$1,880 million, in line with year-end 2025. However, net debt increased to US$1,203 million, reflecting higher disbursements for the development of Rincón de Aranda and collateral requirements linked to crude oil price hedging.

During Q1 26, Pampa canceled US$23 million in bank loans. After quarter-end, Pampa issued CB Series 27 US$-MEP for US$200 million, maturing in April 2029, with a fixed annual interest rate of 5.49% payable semiannually. In addition, Pampa raised US$34 million in bank borrowings. As of March 31, 2026, 97% of total gross debt was issued in the capital markets, with the remaining 3% in bank financing.
