Transportadora de Gas del Sur S.A. reported condensed interim consolidated results for the six months ended June 30, 2025. Total revenues rose by Ps.4,735 million year‑over‑year, driven by the Natural Gas Transportation segment which reached Ps.312,439 million (an increase of Ps.113,877 million). Liquids Production and Commercialization revenues fell to Ps.238,415 million, a decline of Ps.119,520 million, as volumes dispatched decreased 21.9% (118,490 tons).
The Cerri Complex was flooded on March 7, 2025, stopping liquids production through April and producing a reported loss of Ps.33,573,254 including Ps.7,577,663 of PPE impairments. Operating cash flow was Ps.246,970 million (up Ps.29,740 million), but cash and equivalents fell Ps.42,869 million after investing outflows of Ps.86,240 million and financing outflows of Ps.203,599 million, which included a Ps.202,703,683 dividend payment. Regulators completed the Five‑Year Tariff Review with a 3.67% initial increase (31 monthly installments), a 7.18% real after‑tax WACC and a Ps.279,107,575 five‑year investment plan; the government extended tgs’ license by 20 years from Dec. 28, 2027.
Transportadora de Gas del Sur S.A. (TGS) filed a Form 6-K announcing that Argentina’s Executive Branch issued Decree 495/2025, which formally ratifies the Memorandum of Agreement (MOA) signed on 11-Jul-25 to extend TGS’s natural-gas transportation license.
- Term extension: The current license—expiring 28-Dec-27—has been prolonged 20 additional years, now running through 28-Dec-47, under the same regulatory framework established in Decree 2458/1992.
- Conditions: Within 10 business days of the decree’s publication (24-Jul-25), TGS must file documentation proving the withdrawal and waiver of all pending administrative, arbitral or judicial claims—domestic or international—lodged by TGS or its controlling shareholder against the Argentine government.
The extension secures long-term operating visibility for TGS’s core regulated segment, potentially supporting capital-intensive network investments and cash-flow stability. However, relinquishing outstanding claims could forego settlement proceeds and underscores dependence on governmental relations.
