Note: Figures are in thousands of Argentine Pesos (Ps.) as restated for inflation. Total revenues calculated as sum of segments: Natural Gas Transportation (312,439) + Liquids (238,415) + Midstream (increase of 10,379 over prior year base).
Material Changes vs. Prior Period
- Revenue Mix Shift: Natural Gas Transportation revenue grew significantly to Ps. 312,439 million (up Ps. 113,877 million), driven by transitional tariff increases and the new Five-Year Tariff Review (5YTR) framework. Conversely, Liquids Production revenue fell by Ps. 119,520 million due to a 21.9% drop in dispatched volumes and lower international reference prices.
- Impact of Climatic Event: A severe weather event in March 2025 flooded the Cerri Complex, halting liquids production for approximately two months. This resulted in a Ps. 33,573 million loss recorded in "Other operating results" for impairment and expenses.
- Financial Results Deterioration: Financial results worsened by Ps. 95,520 million compared to 6M2024, primarily due to lower yields on financial assets and higher negative losses on net monetary positions, partially offset by foreign exchange losses.
- Dividend Payment: Financing cash outflows increased significantly due to a dividend payment of Ps. 202,704 million approved in May 2025.
Guidance, Outlook, and Risks
Management Commentary and Outlook
- Strategic Focus: Management aims to consolidate growth in the Vaca Muerta region and optimize the production mix in the Liquids segment to prioritize higher-margin products.
- Regulatory Environment: The company secured a 20-year license extension starting December 2027. The 5YTR (2025-2030) established a new tariff adjustment mechanism based on CPI and IPIM, with an initial weighted average increase of 3.67%.
- Expansion Projects: TGS is the sole bidder for the expansion of the Perito Moreno Gas Pipeline (GPM) to increase capacity by 14 MMm³/d. Construction is expected to begin after the October 2025 award.
Risks and Contingencies
- Macroeconomic Volatility: Operations are subject to Argentina's complex economic environment, including inflation (15.1% accumulated as of June 30, 2025) and exchange rate fluctuations.
- Insurance Recovery: The company has property damage and business interruption coverage for the Cerri Complex event, but the final recovery amount and timing remain undetermined due to ongoing negotiations and policy deductibles.
- Regulatory Changes: A new National Gas and Electricity Regulatory Entity was created in July 2025, which may alter the regulatory landscape.
Investor Verification Checklist
- Insurance Recovery Status: Verify the progress of claims regarding the Ps. 33.5 billion loss from the Cerri Complex flood and the expected recovery timeline.
- Tariff Implementation: Confirm the actual application of the new monthly tariff adjustment mechanism (Resolutions 350/2025, 421/2025, 539/2025) and its impact on future cash flows.
- Liquids Segment Recovery: Monitor the full resumption of production volumes at the Cerri Complex and the stabilization of international reference prices for propane and butane.
- Debt Covenants: Review compliance with financial covenants (EBITDA coverage ratio ≥ 2.0:1; Debt/EBITDA ≤ 3.50:1) given the significant dividend payout and inflationary environment.
- Perito Moreno Pipeline Award: Track the official contract award scheduled for October 13, 2025, and the subsequent financing requirements for the 18-month construction period.
