Our highest consideration:

Continuing with what was informed by means of a Relevant Matter dated September 5, 2024 and September 19, 2024, we are writing to you in order to attach the press release regarding the expiration and results of the Expiration Date in connection with the issuance of the Additional Class XXXI Notes, offered in exchange for the 2025 Notes (as defined and set forth in the Exchange Offer Memorandum) (the “Exchange Offer”), which was announced by means of the aforementioned Relevant Matter.

The Exchange Offer is subject to a number of terms and conditions that are described in detail in the Exchange Offer Memorandum published on September 5, 2024 (the “Exchange Offer Memorandum”) in the CNV’s Financial Information Highway, in the Electronic Bulletin of the MAE and in the Electronic Bulletin of the Buenos Aires Stock Exchange.

All capitalized terms not defined herein have the meanings assigned to them in the Exchange Offer Memorandum.

Sincerely yours,

YPF S.A.

YPF Sociedad Anónima Announces Expiration Date Results with respect to its Offer to Exchange up to

U.S.$500,000,000 Aggregate Principal Amount of its 8.500% Senior Notes due July 2025 for the applicable amount of

8.750% Senior Notes due 2031

October 4, 2024— Buenos Aires, Argentina

YPF S.A. (“YPF” or the “Company” or “us” or “we”) today announced the late tender results as of the Expiration Date (as defined below) of its previously announced offer to exchange (the “Exchange Offer”) up to U.S.$500,000,000 in aggregate principal amount (the “Offer Cap”) of its outstanding 8.500% Senior Notes due July 2025 (the “Old Notes”) validly tendered and accepted for exchange for newly issued 8.750% Senior Notes due 2031 (the “New Notes”) of YPF, upon the terms and subject to the conditions set forth in the exchange offer memorandum, dated September 5, 2024 (the “Exchange Offer Memorandum”), and the related electronic eligibility letter (the “Eligibility Letter” and, together with the Exchange Offer Memorandum, the “Exchange Offer Documents”). Capitalized terms used in this press release but not otherwise defined have the meanings given to them in the Exchange Offer Documents.

The Exchange Offer expired at 5:00 p.m., New York City time, on October 3, 2024 (the “Expiration Date”), and is expected to settle on October 7, 2024 (such date, as the same may be extended, the “Final Settlement Date”).

The table below sets forth certain information relating to the Old Notes and the Exchange Offer, including, among other things, the aggregate principal amount of Old Notes tendered after the Early Participation Date and on or prior to the Expiration Date, as well as the Late Participation Consideration. We were advised by the Information and Exchange Agent (as defined below), that as of the Expiration Date, the aggregate principal amounts of Old Notes specified in the table below were validly tendered.

Upon the terms and subject to the conditions set forth in the Exchange Offer Documents, Eligible Holders who validly tendered Old Notes after the Early Participation Date and on or prior to the Expiration Date and whose Old Notes are accepted for exchange by us, will be entitled to receive the Late Participation Consideration detailed in the table above. In addition to the Late Participation Consideration, Eligible Holders who validly tendered Old Notes after the Early Participation Date and on or prior to the Expiration Date will also receive the Accrued Coupon Payment consisting of accrued and unpaid interest on Old Notes accepted for exchange in the Exchange Offer from, and including, the last interest payment date for Old Notes to, but not including, the Final Settlement Date, reduced by the Pre-Issuance Accrued Interest up to, but not including the Final Settlement Date. The Accrued Coupon Payment will be paid in cash with respect to Old Notes accepted for exchange, subject to any tax withholdings applicable to Argentine Entity Offerees or to Non-Cooperative Jurisdictions Offerees. Interest will cease to accrue on the Final Settlement Date. Since the aggregate principal amount of Old Notes validly tendered after the Early Participation Date and on or prior to the Expiration Date, together with the

aggregate principal amount of Old Notes validly tendered (and not validly withdrawn) on or prior to the Early Participation Date, does not exceed the Offer Cap, there will be no proration with respect to such Old Notes.

The New Notes will be issued as Additional New Notes (as defined in the Exchange Offer Memorandum) under the Indenture (as defined in the Exchange Offer Memorandum) pursuant to which the Company issued the New Money Notes on September 11, 2024, as supplemented by a first supplemental indenture dated as of September 20, 2024 and a second supplemental indenture to be dated as of October 7, 2024. The New Notes will constitute a single series with, be assigned the same CUSIP and ISIN numbers as, and have the same terms and conditions as the New Money Notes. Notwithstanding the foregoing, the New Notes offered and sold in reliance on Regulation S will be issued and maintained under temporary ISIN, CUSIP and Common Code numbers during a 40-day distribution compliance period commencing on the date of issuance of the New Notes. After such 40-day distribution compliance period, the New Notes offered and sold in reliance on Regulation S will share the same ISIN and CUSIP numbers as, and will be fungible with, the New Money Notes offered and sold in reliance on Regulation S.

On the terms and subject to the conditions set forth in the Exchange Offer Memorandum, YPF will issue U.S.$461,700 aggregate principal amount of New Notes as exchange consideration for Old Notes validly tendered after the Early Participation Date and on or prior to the Expiration Date and accepted for exchange. Considering the aggregate principal amount of New Money Notes outstanding prior to the Final Settlement Date, the aggregate principal amount outstanding of 8.750% Senior Notes due 2031 after the Final Settlement Date is expected to be U.S.$540,649,400, considering both the New Notes and the New Money Notes in the aggregate.

The settlement of the Exchange Offer for Old Notes tendered after the Early Participation Date and on or prior to the Expiration Date on the Final Settlement Date is subject to the satisfaction of the Tax Fungibility Condition, as set forth in the Exchange Offer Memorandum.

The New Money Notes and, if and when issued, the New Notes will not be registered under the Securities Act, or any state securities law or the securities laws of any other jurisdiction. Therefore, the New Notes and the New Money Notes may not be offered or sold in the United States or to any U.S. persons absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and any applicable state securities laws.

Subject to applicable law and the requirements of the Luxembourg Stock Exchange on which the Old Notes are listed, the Exchange Offer may be amended, extended or, upon failure of a condition to be satisfied or waived prior to the Settlement Date, as the case may be, terminated. Although we have no present plans or arrangements to do so, we reserve the right to amend, at any time, the terms of the Exchange Offer in accordance with applicable law. We will give Eligible Holders notice of any amendments. If the Company terminates, withdraws or otherwise does not consummate the Exchange Offer, the Old Notes tendered pursuant to the Exchange Offer will be promptly returned to the Eligible Holder thereof without compensation or cost to such Eligible Holder, and will remain outstanding.

They may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons except pursuant to an exemption from, or in a transaction not subject to the registration requirements of the Securities Act. This announcement does not constitute an offer of the New Notes for sale, or

the solicitation of an offer to buy any securities, in any state or other jurisdiction in which any offer, solicitation or sale would be unlawful. Any person considering making an investment decision relating to any securities must inform itself independently based solely on an offering memorandum to be provided to eligible investors in the future in connection with any such securities before taking any such investment decision.

●This announcement is directed only to holders of Old Notes who are (i) QIBs, (ii) if outside the United States, holders of Old Notes other than U.S. persons and who are not acquiring New Notes for the account or benefit of a U.S. Person, in offshore transactions in compliance with Regulation S under the Securities Act, and who are Non-U.S. qualified offerees other than Argentine Entity Offerees and Non-Cooperative Jurisdiction Offerees, (iii) Argentine Entity Offerees or (iv) Non-Cooperative Jurisdiction Offerees who are authorized to participate in the Exchange Offer.

The materials relating to the Exchange Offer, including this communication, do not constitute, and may not be used in connection with, an offer or solicitation in any place where offers or solicitations are not permitted by law. If a jurisdiction requires that the Exchange Offer be made by a licensed broker or dealer and a dealer manager or any affiliate of a dealer manager is a licensed broker or dealer in that jurisdiction, the Exchange Offer shall be deemed to be made by the dealer manager or such affiliate on behalf of the Company in that jurisdiction.

●Notice to Investors in the EEA

●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 EEA. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the “IDD”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended or superseded, the “Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling any securities or otherwise making them available to retail investors in the EEA has been or will be prepared and therefore offering or selling any securities or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

●Notice to Investors in the UK
