Ref.: Relevant Fact – Judicial Proceeding in New York

Ladies and Gentlemen,

We are writing to you in order to comply with the CNV Rules and the corresponding regulations of ByMA and A3 Mercados.

In connection with the proceedings brought by Petersen Energía Inversora S.A.U., Petersen Energía S.A.U., Eton Park Capital Management, L.P., Eton Park Master Fund, LTD. and Eton Park Fund, L.P. (collectively, "Plaintiffs") against the Argentine Republic (the "Republic") and YPF S.A. ("YPF" or the "Company"), on March 27, 2026, the United States Court of Appeals for the Second Circuit (the "Second Circuit") affirmed the September 15, 2023 judgment rendered by the United States District Court for the Southern District (the "District Court") in favor of YPF and the dismissal of all of Plaintiffs' claims against YPF. In addition, the Second Circuit reversed the judgment against the Republic on the basis that Plaintiffs' contract claim is not cognizable under Argentine law and vacated the District Court's turnover order in respect of YPF shares held by the Republic.

Plaintiffs may seek to challenge this decision in accordance with applicable procedural rules. If they do so, YPF will continue to defend itself in accordance with the applicable legal procedures and available defenses.

Sincerely,

**Margarita Chun**

Market Relations Officer

YPF S.A
