Of my highest consideration:

NOTICE IS HEREBY GIVEN, in accordance with section 11.7 of the indenture dated February 12, 2021 (the “Indenture”) between YPF Sociedad Anónima (the “Company”), as issuer, The Bank of New York Mellon, as trustee, co-registrar, principal paying agent and transfer agent (the “Trustee”), Banco Santander Río S.A., as registrar, paying agent, transfer agent and representative of the Trustee in Argentina and The Citibank, N.A. Branch established in the Argentine Republic (La Sucursal de Citibank, N.A. establecida en la República Argentina) as onshore collateral agent, has elected to redeem in full the outstanding aggregate principal amount of its 4.000%/9.000% Step Up Secured and Export-Backed Notes due 2026 (the “Notes”) on November 12, 2025 (the “Redemption Date”). Capitalized terms used and not otherwise defined herein shall have the meanings specified in the Indenture.

Pursuant to section 11.7 of the Indenture, the Company will redeem in full the outstanding aggregate principal amount of Notes outstanding on the Redemption Date at a redemption price equal to 100.00% of the principal amount of such Notes, together with accrued interest thereon, including Additional Amounts, if any, to (but not including) the Redemption Date (the “Redemption Price”). Payment of interest on the Notes and Additional Amounts, if any, will be paid as specified in this notice. Unless the Company defaults in paying the Redemption Price or any amounts due and owing under the Notes, interest on Notes called for redemption ceases to accrue on and after the Redemption Date.

Pursuant to Section 4.1 of the Indenture, YPF has instructed the Trustee to instruct the Offshore Collateral Agent to in turn instruct the Reserve and Payment Account Bank in accordance with the applicable Account Control Agreement to transfer to the Trustee any amounts held in the Reserve and Payment Account for application to the Payment of the Redemption Price on the Redemption Date.

Payment on the Notes will be made on the Redemption Date by payment of the Redemption Price, which will be deposited with the Trustee by the Reserve and Payment Account Bank (acting pursuant to instructions from the Company through the Trustee and the Offshore Collateral Agent in accordance with the applicable Account Control Agreement) in immediately available funds prior to the Redemption Date. The Trustee, as paying agent under the Notes, will cause funds to be paid to The Depository Trust Company for further payment to its participants.

The Notes called for redemption must be surrendered to the Trustee, as the Paying Agent, at the following address in order to collect the Redemption Price:
