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.

Sincerely yours,

YPF S.A.

YPF Sociedad Anónima Announces Early Participation 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

September 19, 2024— Buenos Aires, Argentina

YPF S.A. (“YPF” or the “Company” or “us” or “we”) today announced the early tender results as of 5:00 p.m. (New York City time) on September 18, 2024 (the “Early Participation Date”) 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 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 on or prior to the Early Participation Date and the Early Participation Consideration (as defined below). We were advised by the Information and Exchange Agent (as defined below), that as of the Early Participation Date, the aggregate principal amounts of Old Notes specified in the table below were validly tendered and not validly withdrawn.

Upon the terms and subject to the conditions set forth in the Exchange Offer Documents, Eligible Holders who validly tendered (and did not validly withdraw) Old Notes at or prior to the Early Participation Date (as defined below) and whose Old Notes are accepted for exchange by us, will be entitled to receive the Early Participation Consideration detailed in the table above. In addition to the Early Participation Consideration, Eligible Holders who validly tendered (and did not validly withdraw) Old Notes at or prior to the Early Participation 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 Early Settlement Date, reduced by the Pre-Issuance Accrued Interest up to, but not including the Early 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 Early Settlement Date. Since 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.

Withdrawal rights for the Exchange Offer expired at 5:00 p.m., New York City time on Wednesday, September 18, 2024. Old Notes that have been validly tendered on or prior to the Early Participation Date cannot be withdrawn, except as may be required by applicable law. YPF has elected to exercise its right to accept the Old Notes validly tendered at or prior to the Early Participation Date and exercise its Early Settlement Right. The early settlement date on which YPF will settle the Old Notes accepted in the Exchange Offer is expected to be September 20, 2024 (the “Early Settlement Date”). The Exchange Offer is scheduled to expire at 5:00 p.m. (New York City time) on October 3, 2024 unless extended or earlier terminated (such date and time with respect to the Exchange Offer, as the same may be extended with respect to the Exchange Offer, the “Expiration Date”).

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 to be dated as of September 20, 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.$40,187,700 aggregate principal amount of New Notes as exchange consideration for Old Notes accepted in connection with our Early Settlement Right. Considering the aggregate principal amount of New Money Notes outstanding prior to the Early Settlement Date, the aggregate principal amount outstanding of 8.750% Senior Notes due 2031 after the Early Settlement Date is expected to be U.S.$540,187,700, considering both the New Notes and the New Money Notes in the aggregate.

Given that the Early Settlement Date is expected to occur within thirteen days of the settlement of the New Money Notes, for U.S. federal income tax purposes, the New Notes will be part of the same issue as the New Money Notes.

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 Expiration Date or 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 and will extend the Expiration Date if required by applicable law. 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.

The complete terms and conditions of the Exchange Offer are described in the Exchange Offer Memorandum, copies of which may be obtained from Morrow Sodali International LLC, trading as Sodali & Co, the information and exchange agent for the Exchange Offer by telephone at +1 203 658 9457 (Stamford) or +44 20 4513 6933 (London), in writing at 333 Ludlow Street, South Tower, 5th Floor Stamford, CT 06902, United States, by email to YPF@investor.sodali.com, or are available for download via the website https://projects.sodali.com/YPFexchange.
