Re: YPF enters into a share purchase and sale agreement to acquire

Mobil Argentina S.A.

Dear Sir or Madam,

The purpose of this letter is to comply with the requirements of the Rules of the Comisión Nacional de Valores (the “CNV”). On behalf of YPF S.A. (the “Company” or “YPF”), located at Macacha Guemes 515, City of Buenos Aires, we inform you that on December 17, 2024, the Company entered into a share purchase and sale agreement (the “Agreement”) with ExxonMobil Argentina Upstream B.V., ExxonMobil Exploration and Production Gemini B.V., and QatarEnergy Argentina Holdings LLC (the “Sellers”) –the former two are companies of the ExxonMobil Group and the latter is a company of the QatarEnergy Group– pursuant to which, subject to the satisfaction of the conditions precedent set forth in the Agreement, YPF will acquire one hundred percent (100%) of the shares and capital stock of Mobil Argentina S.A. (“MASA”).

MASA owns around fifty-four point four five percent (~54.45%) of the unconventional exploitation concession of the Sierra Chata area, in the province of Neuquén. Pampa Energía S.A. owns the remaining interest and operates the area.

Sierra Chata is one of Vaca Muerta’s highest potential shale gas assets, with a total area of 864 squared kilometer.

Sincerely,

SIGNATURE
