Material Changes vs. Prior Period
- Revenue Mix Shift: Liquids Production and Commercialization revenues grew by Ps. 127,421 million (driven by a >50% volume increase), while Natural Gas Transportation revenues declined by Ps. 14,735 million due to inflation outpacing tariff adjustments.
- Operational Recovery: The Liquids segment benefited from a base effect; 6M2025 was negatively impacted by a severe weather event in March 2025 that halted operations for two months. 6M2026 reflects full operational recovery.
- Financial Results: Net financial results dropped significantly (Ps. 50,320 million decrease) due to lower yields on financial investments and a higher negative impact from inflation exposure (Ps. 62,084 million loss vs. Ps. 43,115 million in 6M2025).
- Other Operating Results: Turned from a loss of Ps. 43,296 million in 6M2025 to a profit of Ps. 9,361 million in 6M2026, primarily due to insurance recoveries related to the 2025 weather event.
Guidance, Outlook, and Risks
Strategic Initiatives
- Integrated NGLs Project: Final Investment Decision (FID) announced June 10, 2026. Estimated investment of US$ 3,000 million. Includes a 100-km gas segregation pipeline, Tratayén Plant expansion, and a marine terminal in Bahía Blanca. Expected to generate US$ 1,200 million in annual exports.
- Perito Moreno Expansion: Public tender awarded 5.4 MMm³/d of incremental capacity in April 2026, with remaining capacity awarded in June 2026. Project approved under the Incentive Regime for Large Investments (RIGI).
Management Commentary & Risks
- Regulatory Environment: The Secretariat of Energy redefined the contractual framework for Natural Gas Transportation (Resolution 66/2026) to adapt to the Vaca Muerta production profile. While the Required Revenue under the 5-Year Tariff Review remains unchanged, tariff adjustments have not fully offset inflation.
- Macroeconomic Context: Argentina continues to face high inflation and volatility. The company applies IAS 29 for hyperinflationary economies. Management emphasizes prudent capital allocation and liquidity preservation.
- Climate Risk: The March 2025 weather event caused significant disruption. While operations have recovered, the company continues to quantify insurance claims for property damage and business interruption.
Investor Verification Checklist
- Inflation Impact: Verify the specific CPI indices used for restatement (17.09% for 6M2026) and the adequacy of tariff adjustments in the regulated transportation segment.
- Project Execution: Monitor the timeline and cost management of the US$ 3,000 million Integrated NGLs Project and the Perito Moreno expansion.
- Liquidity Position: Assess the sustainability of the net cash decrease (Ps. 542,246 million) given the heavy investment cycle and the absence of dividend payments in the current period.
- Insurance Recovery: Track the final settlement of the insurance claim related to the March 2025 Cerri Complex flood, as only an advance payment has been received to date.
- Debt Covenants: Confirm continued compliance with financial covenants (EBITDA coverage ratio ≥ 2.0:1; Debt/EBITDA ≤ 3.50:1) following the issuance of the 2035 Notes.
