Transportadora de Gas del Sur S.A. (TGS, the company) announced that it has commenced a cash tender offer, on the terms and subject to the conditions set forth in the Company?s Offer to Purchase for Cash dated July 15, 2024 (the Offer to Purchase), for any and all of its outstanding 6.750% Senior Notes due 2025 (the Notes). The Offer will expire at 5:00 p.m., New York City time, on July 19, 2024, unless extended or terminated earlier at the sole discretion of the Company (such date and time, as it may be extended or terminated earlier, the Expiration Date). Subject to the satisfaction of the terms and conditions set forth in the Offer to Purchase, holders validly tendering and not withdrawing their Notes pursuant to the Offer will be entitled to receive USD 1,000 per USD 1,000 principal amount of the Notes tendered (the Offer Consideration), on a date promptly following the Expiration Date (the Settlement Date) (which date is expected to occur within three business days of the Expiration Date, but which may change without notice).

The settlement date in respect of Notes for which a properly completed guaranteed delivery instruction is submitted at or prior to the Expiration Date and which are validly tendered at or prior to the guaranteed delivery date that are accepted by the Company for purchase in the Offer is expected to be the Settlement Date. Tendered Notes may be validly withdrawn from the Offer at any time at or prior to the earlier of the Expiration Date and in the event that the Offer is extended, the tenth business day after commencement of the Offer, and after the 60th business day after commencement of the Offer if for any reason the Offer has not been consummated within 60 business days after commencement. The Company?s obligation to accept for purchase and to pay for Notes validly tendered and not withdrawn pursuant to the Offer is subject to the satisfaction or waiver, in the Company?s discretion, of certain conditions, which are more fully described in the Offer, including the financing condition requiring the consummation of the Company?s concurrent offering of senior notes, and other general conditions described in the Offer to Purchase.

The Company has retained Citigroup Global Markets Inc., Itau BBA USA Securities Inc., J.P. Morgan Securities LLC and Santander US Capital Markets LLC. to serve as the dealer managers for the Offer, and Banco Santander Argentina S.A. to act as local information agent in Argentina. The new notes offered pursuant to the concurrent offering have not been and will not be registered under the U.S. Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act.

The new notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (EEA). For these purposes, a retail investor means a person who is one (or more) of: a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, MiFID II); or a customer within the meaning of Directive (EU) 2016/97 (as amended, the Insurance Distribution Directive), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the Prospectus Regulation). Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the PRIIPs Regulation) for offering or selling the new notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the new notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.
