Buenos Aires, Argentina, March 4, 2024

During the 4Q2023, total comprehensive loss amounted to Ps. 23,461 million, or a Ps. 31.17 loss per share (Ps. 155.84 per ADS), compared to a total comprehensive income of Ps. 16,697 million, or Ps. 22.17 per share (Ps. 110.83 per ADS) in the fourth quarter ended on December 31, 2022 ("4Q2022").

Operating profit for 4Q2023 totaled Ps. 22,647 million, which was Ps. 7,968 million below 4Q2022. This variation was mainly due to lower revenues from the Production and Commercialization of Natural Gas Liquids (Liquids) and Natural Gas Transportation segments amounting to Ps. 26,124 million and Ps. 6,492 million, respectively.

These effects were partially offset by higher revenues from Midstream and Other Services segment ("Midstream") amounting to Ps. 11,735 million and lower operating costs of Ps. 13,238 million.

Financial results recorded a negative variation of Ps. 63,673 million.

4Q2023 EARNINGS RELEASE

Highlights during 4Q2023 and beyond

ØIn December 2023 the Mercedes - Cardales natural gas pipeline began operations. Through this complementary work to the President Nestor Kirchner natural gas pipeline ("GPNK"), carried out by Energía Argentina S.A. ("ENARSA"), more flexibility is provided to transfer natural gas between the transportation systems operated by tgs and Transportadora de Gas del Norte S.A. in the Great Buenos Aires area. It should be noted that tgs was contracted by ENARSA for the operation and maintenance of this natural gas pipeline.

ØOn December 14, 2023, ENARGAS' Resolution No. 704/2023 called for a public hearing hold on January 8, 2024, in order to submit for consideration a transitory tariff increase. As of the date of this press release, the corresponding regulations authorizing a resulting transitory tariff increase have not been issued.

Analysis of the results

Total revenues amounted to Ps. 102,476 million in 4Q2023, a Ps. 20,882 million decrease compared to Ps. 123,358 million in 4Q2022.

The breakdown of cost of sales, administrative and selling expenses, excluding depreciation, for 4Q2023 and 4Q2022 is shown in the table below:

Cost of sales and administrative and selling expenses decreased by Ps. 13,238 million in 4Q2023 from 4Q2022. This variation was due to the lower cost of natural gas consumed for liquids production equivalent to Ps. 18,682 million (IAS 29 restatement effect and lower volume consumed, partially offset by the higher price). This effect was partially offset by higher labor costs of Ps. 2,307 million, by higher PPE repair and maintenance and third parties services expenses of Ps.1,586 million and an additional depreciation of Ps. 1,320 million.

Financial results are presentedin gross terms considering the effect of change in the currency purchasing power ("(Loss) / gain on monetary position") in a single separate line. In 4Q2023, the financial results registered a negative variation of Ps. 63,673 million compared to

4Q2023 EARNINGS RELEASE

4Q2022. This variation mainly reflects a higher exchange rate loss amounting to Ps. 89,128 million (as a consequence of a greater exchange rate depreciation during 4Q2023) and the negative variation on monetary position results of Ps. 43,619 million. These effects were partially offset by higher positive result generated by financial assets totaling Ps. 72,507 million.

Natural Gas Transportation

Operating loss of the Natural Gas Transportation segment was Ps. 11,376 million in 4Q2023 compared to a loss of Ps. 112 million in 4Q2022.

Natural gas transportation revenues accounted for approximately 20% and 22% of total revenues in 4Q2023 and 4Q2022, respectively.

Revenues from this segment are derived mainly from firm natural gas transportation contracts, which represented approximately 78% and 80% of the total revenues for this segment in 4Q2023 and 4Q2022, respectively.

4Q2023 EARNINGS RELEASE

This tariff segment, subject to ENARGAS regulation, received its last increase on April 29, 2023 at 95%. Prior to that, tgs was allowed a 60% tariff increase that became effective as of March 1, 2022.

The increase in operating loss was mainly due to lower revenues that showed a decrease of Ps. 6,493 million as a result of the tariff adjustment given was not sufficient to offset the negative variation of the inflation restatement effect under IAS 29, and higher operating costs of Ps. 4,660 million.

Liquids Production and Commercialization

Liquids Production and Commercializationrevenues accounted for approximately 54% and 66% of total revenues in 4Q2023 and 4Q2022, respectively. During 4Q2023, production decreased by 44,534 tons, reaching 286,818 tons.

The operating profit of this business segment for 4Q2023 totaled Ps. 20,789 million, Ps. 4,865 million below the Ps. 25,654 million recorded in 4Q2022. This decrease was mainly due to lower revenues amounting to Ps. 26,124 million, which were partially offset by the lower cost of natural gas consumed of Ps. 18,682 million.

In terms of the Liquids revenues, which amounted to Ps. 55,303 million in 4Q2023, or 32% below the Ps. 81,427 million in 4Q2022, we highlight the impact of the restatement in accordance with IAS 29 of Ps. 46,700 million, the decline in propane's international reference prices of Ps. 4,691 million, lower volume sold of Ps. 12,052 million, and decrease in the price of ethane sold of Ps. 2,106 million. These effects were partially offset by the nominal variation of the exchange rate on U.S. dollar-denominated revenues amounting to Ps. 37,791 million, the increase in services rendered of Ps. 2,075 million and the higher price of butane sold under the Plan Hogar of Ps. 1,298 million.

Total volume dispatched decreased 19%, or 65,057 tons, compared to 4Q2022. This decline was mainly related to lower tons of propane and butane sold in foreign market and ethane dispatched (due to the customer's inability to take the product).

The breakdown of volumes dispatched by market and product and revenues by market is included below:

4Q2023 EARNINGS RELEASE

Midstream and Telecommunications

Midstream and Telecommunications business segments include mainly services provided by tgs in Vaca Muerta, representing approximately 26% and 12% of our total revenues for 4Q2023 and 4Q2022, respectively.

Operating profit rose by Ps. 8,160 million mainly as a result of the Ps. 11,735 million increase in revenues during 4Q2023, which was partially offset by higher operating costs of Ps. 3,528 million.

The increase in revenues was primarily explained by higher natural gas transportation and conditioning services at Vaca Muerta amounting to Ps. 11,595 million, the nominal effect of the exchange rate on U.S. dollar-denominated revenues of Ps. 4,802 million and increased in services related to the GPNK operation and maintenance and complementary works for Ps.

4Q2023 EARNINGS RELEASE

1,309 million. These effects were partially offset by the impact of the IAS 29 restatement of Ps. 6,777 million.

Financial position analysis

Net debt

During 4Q2023 the Company incurred in a new bank debt amounting to Ps. 17,366 million (US$ 39.3 million). In addition, loans amounting to Ps. 9,806 million (US$ 21.1 million) were cancelled.

4Q2023 EARNINGS RELEASE

The table below shows a reconciliation of the free cash flows for the 4Q2023 and 4Q2022 periods:

4Q2023 vs. 4Q2022

During 4Q2023, the cash flow provided by operating activitiesamounted to Ps. 52,336 million, while in 4Q2022 the cash flow provided by operating activities totaled Ps. 14,773 million. This was mainly due to higher exchange rate differences generated by trade and other receivables as well as a lower income tax payment (the balance of which was cancelled through the use of tax credits).

Cash flow used in investing activitiesamounted to Ps. 62,105 million in 4Q2023, compared to Ps. 28,958 in 4Q2022. This increase was mainly related to higher payments for the acquisition of non-cash investments and higher payments for the acquisition of PPE as part of the investment plan in Vaca Muerta.

Finally, cash flow used in financing activitiesincreased by Ps. 7,344 million, compared to Ps. 571 million in 4Q2022. This was mainly due to the proceeds from new loans.
