Filing Type: Form 6-K (Annual Report and Financial Statements)
Reporting Period: Year ended December 31, 2024
Business Overview: tgs is a leading integrated energy services provider in Argentina, operating in three main segments: Natural Gas Transportation (regulated), Liquids Production and Commercialization, and Midstream/Telecommunications.

Key Financial Metrics (Year Ended Dec 31, 2024)

Figures stated in millions of constant Argentine Pesos (Ps.) unless otherwise noted.

Segment Performance:

• Natural Gas Transportation: Revenues of Ps. 441,126 million (up from Ps. 215,700 million). Operating income turned positive at Ps. 220,453 million, reversing a Ps. 26,640 million loss in 2023.
• Liquids Production: Revenues of Ps. 556,662 million (down Ps. 21,311 million). Operating income increased to Ps. 223,155 million.
• Midstream: Revenues of Ps. 221,978 million (up Ps. 29,598 million). Operating income reached Ps. 116,691 million.

Material Changes vs. Prior Period

• Tariff Adjustments: The most significant driver of 2024 results was a 675% tariff increase in the Natural Gas Transportation segment effective April 3, 2024, followed by monthly adjustments. This restored profitability to the segment after years of losses.
• Asset Impairment Reversal: Due to improved cash flow projections from tariff hikes, tgs recorded a reversal of impairment on Property, Plant, and Equipment (PPE) of Ps. 39,625 million in the Transportation segment.
• Financial Results: Net financial results improved by Ps. 180,050 million year-over-year, driven by a lower negative foreign exchange difference and a net active monetary position (assets exceeding liabilities) which generated a gain on inflation exposure.
• Production Volumes: Liquids production totaled 1,051,654 tons, a decrease of 82,643 tons from 2023, primarily due to major maintenance at the Cerri Complex. However, export volumes increased by 51,058 tons.

Guidance, Outlook, and Risks

Management Commentary and Outlook

• Tariff Review (RQT): The company is finalizing the Five-Year Tariff Review (RQT) with ENARGAS. A public hearing was held in February 2025. tgs requested a 22.7% tariff increase and a WACC of 9.98%, while ENARGAS proposed a WACC of 7.18%. Final resolution is expected by July 9, 2025.
• License Extension: tgs expects its operating license to be extended until December 2047, following a satisfactory technical report from ENARGAS.
• Investment Projects:
  • Perito Moreno Pipeline (GPM): Submitted a private initiative to expand capacity by 14 MMm3/d (approx. US$ 500 million investment). Declared of national public interest in December 2024.
  • Tratayén Plant: Expanded conditioning capacity to 28 MMm3/d with the startup of the second Propak module in February 2025.
  • Future Processing: Assessing a project to convert the Tratayén plant into a full processing facility (40 MMm3/d) with a polyduct to Bahía Blanca for liquid exports.

Risks and Contingencies

• Regulatory Uncertainty: The outcome of the RQT and the finalization of the "Law of Bases" (Ley Bases) remain critical uncertainties affecting future tariff frameworks and legal security.
• Macroeconomic Volatility: Argentina's high inflation (117.8% in 2024) and exchange rate fluctuations (Peso devalued 27.7% vs. USD) continue to pose risks, though the company maintains a net monetary asset position to mitigate inflationary losses.
• Government Receivables: As of December 31, 2024, the Argentine State owed tgs Ps. 10,882 million in compensation for the "Propane for Networks" agreement, with payments delayed.
• Legal Claims: Ongoing litigation regarding the annulment of ENARGAS resolutions related to the "Charge" for natural gas imports (Decree 2067/08) remains pending before the Supreme Court.

Investor Verification Checklist

• Tariff Resolution: Verify the final outcome of the Five-Year Tariff Review (RQT) and the approved WACC rate, as this dictates future revenue stability.
• License Extension Decree: Confirm the issuance of the Executive Branch decree extending the operating license to 2047.
• Government Receivables: Monitor the collection status of the Ps. 10.9 billion owed by the state for propane supply programs.
• Debt Covenants: Review compliance with covenants on the new US$ 490 million 2031 Notes (e.g., EBITDA coverage ratio > 2.0:1).
• Private Initiative Bidding: Track the status of the bidding process for the Perito Moreno Pipeline expansion project.
• Inflation Impact: Assess the continued effectiveness of the company's net monetary asset position in offsetting inflationary losses in the hyperinflationary Argentine environment.
