The Tender Offers are subject to the terms and conditions set forth in YPF’s Offer to Purchase dated the date hereof (the “Offer to Purchase”), including the concurrent or earlier consummation of a new notes offering that provides YPF with sufficient funds to meet the obligations of YPF in connection with the Tender Offers.

Under the Acceptance Priority Procedures, Securities will be accepted for purchase according to the Acceptance Priority Level set forth in the table above, beginning with the lowest numerical value first. When considering any potential allocation of New Notes in the New Notes Offering, YPF intends, but is not obligated, to give some degree of preference to those investors who, prior to such allocation, have validly tendered, or have indicated to YPF or the Dealer Managers (as defined below) their firm intention to tender, Securities in the Tender Offers. The Offer to Purchase more fully sets forth the terms of the Tender Offers. The Tender Offers are scheduled to expire at 5:00 p.m., New York City time (6:00 p.m. Buenos Aires time), on Wednesday, September 16, 2026, unless extended or earlier terminated (such date and time, as it may be extended with respect to the Tender Offers, the “Expiration Date”). Holders of Securities (“Holders”) may participate in the Tender Offers by validly tendering and not validly withdrawing their Securities by the Expiration Date.

Securities validly tendered pursuant to the Tender Offers may be withdrawn at any time at or prior to 5:00 p.m., New York City time (6:00 p.m. Buenos Aires time), on Wednesday, September 16, 2026 (such date and time, as it may be extended with respect to the Tender Offers, the “Withdrawal Deadline”), but not thereafter. The Withdrawal Deadline for the Tender Offers is the same as the Expiration Date.

It is expected that the Settlement Date for the Tender Offers will be on or around Friday, September 18, 2026, the second business day after the Expiration Date, but which may change without notice (the “Settlement Date”). Payment for the Securities that are validly tendered and accepted for purchase pursuant to the Tender Offers will be made on the Settlement Date. YPF will not be responsible for any delays in the transmission of funds to Holders attributable to the clearing systems and under no circumstances will any interest be payable because of any such delay.

Subject to the terms and conditions described in the Offer to Purchase, Holders who validly tender their Securities at or prior to the Expiration Date will receive the applicable Consideration specified in the table above payable for such tendered Securities that are accepted for purchase by YPF. In addition, YPF will pay accrued and unpaid interest on the Securities up to, but not including, the Settlement Date (“Accrued Interest”). Payment of the Consideration and Accrued Interest will be made on the Settlement Date.

YPF reserves the absolute right to amend, extend, terminate or withdraw any or all of the Tender Offers in its sole discretion, subject to disclosure and as otherwise required by applicable law. Any (i) increase or decrease in the percentage of Securities sought in a Tender Offer, other than the acceptance for purchase of an additional amount of Securities not to exceed two percent of the applicable series of Securities, or (ii) change in the Consideration offered, will be communicated by public announcement that is widely disseminated no later than 9:00 a.m., New York City time (10:00 a.m. Buenos Aires time), on the third business day before the Expiration Date. Any other material change in the terms of a Tender Offer will be communicated by public announcement that is widely disseminated no later than 9:00 a.m., New York City time (10:00 a.m. Buenos Aires time), on the second business day before the Expiration Date. In the event of termination or withdrawal of a Tender Offer, Securities tendered and not accepted for purchase pursuant to such Tender Offer will be promptly returned to the tendering holders.
