Dear Sirs,

I am writing to you in my capacity as Head of Market Relations of Transportadora de Gas del Sur S.A. (“tgs”), in order to report that, in its meeting held today, the Board of Directors approved the execution of an addendum to the transportation and conditioning services agreement in connection with the gas provided by Pampa Energía S.A. coming from El Mangrullo, in Vaca Muerta (the “Addendum”).

The Addendum extends the validity term of the existing transportation, conditioning and bypass services until December 31, 2033, and commits to the provision of additional amounts for each of the above-mentioned services until a total amount of 11.5 million daily cubic meters is reached for the firm transportation, conditioning and bypass services. The total turnover for the services throughout the validity term of the agreement is estimated to be US$ 285 million and it shall require an estimated investment of up to US$ 138 million.

Prior to the above-mentioned approval, tgs Audit Committee was asked to issue a report in compliance with section 72 of Capital Markets Act no. 26,831. On August 9, 2022, the Audit Committee concluded that the Addendum can be deemed to be reasonably entered into on an arm’s length basis.

The Audit Committee’s report is available for consultation by accredited shareholders if so desired, upon request via email at: direcciondelegales@tgs.com.ar.

Yours sincerely,

Hernán Diego Flores Gómez

Head of Market Relations
