(1)Operating profit before depreciation and reversal of climate event impairment of PPE is a non-IFRS financial measure, we define the operating profit before depreciation as operating profit plus depreciation of PPE. We believe that this measure provides complementary information to investors and stakeholders for decision making process. Operating profit before depreciation and reversal of climate event impairment should not be interpreted as an alternative to other measures calculated in accordance with IFRS as it may not be comparable with similar denomination measures reported by other entities.

Operating profit for the 3Q2025 totaled Ps. 172,026 million, an increase of Ps. 33,567 million compared to 3Q2024. This variation was mainly driven by higher revenues from the Liquids Production and Commercialization and Midstream segments, which rose by Ps. 70,423 million and Ps. 24,851 million, respectively.

On the other hand, revenues from the Natural Gas Transportation segment decreased by Ps. 6,682 million, partially offsetting the positive effects mentioned above.

(1)The financial information included in this press release is based, unless otherwise stated, on the interim condensed financial statements and is presented in millions of constant Argentine pesos as of September 30, 2025 (Ps.), which is based on the application of International Financial Reporting Standards ("IFRS").

Net cost of sales and administrative and selling expenses increased by Ps. 45,571 million, while other operating results declined by Ps. 9,453 million.

Financial results grew by Ps. 31,087 million.



Highlights during 3Q2025 and beyond
  • Following the national and international public tender organized by Energía Argentina S.A. ("ENARSA") to expand the Perito Moreno Pipeline (GPM) - aimed at increasing natural gas transportation capacity at Vaca Muerta by 14 MMm³/d -, tgs was awarded the execution of the project on October 17, 2025. This initiative involves an estimated investment of US$ 560 million and has been declared of public interest, as it supports the growth of natural gas transportation capacity from Vaca Muerta.

  • Additionally, tgs will execute an investment of approximately US$ 220 million to expand the transportation capacity of natural gas by 12 MMm³/d in the final sections of the pipeline system operated within the Natural Gas Transportation segment.

Analysis of the results

In the 3Q2025, tgs reported revenues of Ps. 426,518 million, compared to Ps. 337,928 million recorded in 3Q2024, representing an increase of Ps. 88,591 million.

Net cost of sales and administrative and selling expenses increased by Ps. 45,571 million, mainly due to higher: (i) cost of natural gas purchased for liquids production - primarily driven by increased consumption and, to a lesser extent, by the inflation-adjusted price under IAS 29 - amounting to Ps. 28,470 million; (ii) depreciation charges of Ps. 7,804 million; (iii) repair and maintenance expenses of Ps. 6,311 million; and, (iv) taxes, fees and contributions of Ps. 5,090 million, mainly related to higher export duties. These effects were partially compensated by lower labor costs amounting to Ps. 2,132 million. Financial results are presented on a nominal basis, with the impact in the monetary position shown as a single line item. In 3Q2025, negative financial results decreased by Ps. 31,087 million compared to 3Q2024. This improvement was mainly driven by higher returns on financial assets totaling Ps. 43,406 million and a lower loss on monetary position of Ps. 10,726 million. These effects were partially offset by a higher negative foreign exchange difference of Ps. 21,759 million. Other net operating results reported a loss of Ps. 8,870 million in 3Q2025, compared to a gain of Ps.

583 million in 3Q2024. The negative variation was attributable to a Ps. 10,248 million loss related to expenses and impairment of materials and other PPE items associated with the weather event that occurred on March 7, 2025, at the Cerri Complex. This impact was partially offset by insurance recoveries amounting to Ps. 1,292 million.



Natural Gas Transportation

Operating profit of the Natural Gas Transportation segment totaled Ps. 77,515 million in 3Q2025, Ps. 8,625 million below 3Q2024.

Natural gas transportation revenues accounted for approximately 37% and 49% of total revenues in 3Q2025 and 3Q2024, respectively.

Revenues from this segment are derived mainly from firm natural gas transportation contracts, which represented approximately 82% and 84% of the total revenues for this segment in 3Q2025 and 3Q2024, respectively.

The decline in operating profit was mainly explained by a Ps. 6,682 million decrease in revenues, driven by the Ps. 42,168 million negative impact from inflation adjustment to constant currency under IAS 29. This effect was partially offset by tariff increases (Ps. 29,157 million) and higher revenues from natural gas transportation services (Ps. 4,049 million).

Net cost of sales, administrative and selling expenses rose by Ps. 3,296 million, primarily due to higher operating and maintenance expenses for the pipeline system (Ps. 3,814 million) and increased depreciation charges (Ps. 1,674 million). These effects were partially compensated by lower labor costs (Ps. 1,320 million), reduced taxes, rates, and contributions - mainly due to lower gross income tax charges (Ps. 675 million) -, and the recovery of impaired trade receivables from a single customer (Ps. 458 million).



Liquids Production and Commercialization Liquids Production and Commercialization revenues accounted for approximately 42% and 32% of total revenues in 3Q2025 and 3Q2024, respectively. During 3Q2025, production increased by 142,182 tons, reaching 314,863 tons.

During the 3Q2025, operating profit for this business segment reached Ps. 48,708 million, representing an increase of Ps. 33,574 million compared to the same period in 2024 (Ps. 15,134 million). This increase was mainly driven by a Ps. 70,423 million increase in revenues. This effect was partially offset by higher natural gas costs (Ps. 28,469 million), higher charges in other net operating results of Ps. 6,722 million - primarily attributable to the impact of the previously mentioned weather event -, and higher export taxes and turnover tax totaling Ps. 3,955 million.

Revenues amounted to Ps. 177,156 million in 3Q2025, compared to Ps. 106,733 million in the same period of 2024. This increase was mainly explained by: (i) higher volumes sold (Ps. 58,250 million), (ii) a higher nominal exchange rate (Ps. 23,653 million), and (iii) higher domestic prices of propane and butane (Ps. 15,383 million). These effects were partially offset by a Ps. 25,336 million loss resulting from the inflation adjustment under IAS 29.

In terms of volumes sold, an increase of 103,445 tons (or 52%) was recorded compared to 3Q2024. This growth was primarily driven by the improved quality of natural gas processed at the Cerri Complex and greater operational reliability, which led to higher liquids production. It is worth noting that the comparison is also impacted by the scheduled plant shutdown that took place during 3Q2024, which lasted three weeks.

Operating profit rose by Ps. 8,618 million, mainly driven by a Ps. 24,851 million increase in revenues in 3Q2025 compared to 3Q2024. This effect was partially offset due to a higher net cost of sales and administrative and selling expenses totaling Ps. 15,777 million.

The increase in revenues was primarily related to higher natural gas transportation and conditioning services at Vaca Muerta (Ps. 20,949 million), as well as the nominal exchange rate effect on U.S. dollar-denominated sales (Ps. 19,796 million). These positive impacts were partially offset by a Ps. 16,586 million loss resulting from the inflation adjustment under IAS 29.

3Q2025 vs. 3Q2024

During the 3Q2025, the cash flow provided by operations activities totaled Ps. 149,910 million, representing a decrease of Ps. 9,299 million compared to the same period of the previous year (Ps. 159,209 million in 3Q2024). This variation was mainly explained by higher income tax payments (Ps. 60,832 million vs. Ps. 100 million) and increased interest payments (Ps. 28,972 million vs. Ps. 9,855 million). These effects were partially compensated by a higher inflow from working capital (Ps. 36,450 million vs. Ps. 10,807 million in 3Q2024). These effects were partially compensated by the positive impact of higher comprehensive net income (Ps. 112,059 million vs. Ps. 68,802 million) and a slight increase in adjustments for eliminations (Ps. 91,205 million vs. Ps. 89,555 million).

This decrease of Ps. 67,639 million was mainly explained by lower payments for the acquisition of investments not classified as cash equivalents (Ps. 83,875 million). This effect was partially offset by higher payments for the acquisition of property, plant and equipment (PPE) amounting to Ps. 16,236 million.

Non-IFRS Financial Measures

This press release also includes certain non-IFRS financial measures. Non-IFRS financial measures are not measurements of our performance or liquidity under IFRS as issued by IASB and should not be considered alternatives to operating profit or profit for the period or net cash provided by operating activities or any other performance measures derived in accordance with IFRS as issued by the IASB or any other generally accepted accounting principles or as alternatives to cash flow from operating, investing or financing activities.

We present non-IFRS financial measures because we believe that they and other similar measures are widely used by certain investors, securities analysts and other interested parties as supplemental measures of performance and liquidity. The non-IFRS financial measures may not be comparable to other similarly titled measures employed by other companies and may have limitations as analytical tools. These measures may not be fit for isolated consideration or as a substitute for analysis of our operating results as reported under IFRS as issued by the IASB. Non-IFRS financial measures and ratios are not measurements of our performance or liquidity under IFRS as issued by the IASB.
