PELLEGRINI S.A.U. (“OLCLP” and jointly with YPF VENTURES, the “Absorbed Companies), which shall be dissolved without going into liquidation. The effects of the Merger are described below.

1. Transfer of assets and liabilities

The Absorbed Companies’ assets and liabilities shall be transferred to YPF, which shall then incorporate into YPF´s equity all the assets, liabilities, rights and obligations of the said companies. The assets and liabilities of the Absorbed Companies shall be incorporated into YPF’ equity at the value thereof recorded in the respective Special-Purpose Merger Financial Statements as of December 31, 2025, effective as from January 1, 2026. Such incorporation shall include the rights and obligations which, for whatever reason, have not been contemplated in the respective Special-Purpose Merger Financial Statements as of December 31, 2025, including all rights and obligations arising or known after the closing date of such Special-Purpose Merger Financial Statements as of December 31, 2025 (i.e., December 31, 2025) as a consequence of acts or activities prior to the closing date.

According to the title reports required by the Real Estate Registry and the Motor Vehicle Registry, there are no registrable assets owned by the Merging Companies that will be transferred to the Absorbing Company as a result of the Merger. It is hereby noted that, as of the date of publication of this Prospectus, the title report from the Real Estate Registry of the Province of Río Negro is pending receipt by OLCLP. In the event that the aforementioned report contains information that must be disclosed, the investor public will be notified in accordance with applicable regulations.

2. Dissolution of the Absorbed Companies

YPF VENTURES AND OLCLP shall be dissolved without liquidation, in compliance with the provisions of Section 94, subsection 7 of the LGS, and the shares representing their capital stock shall consequently be canceled.

3. Exchange Ratio

In light of the fact that, as of the date of the Extraordinary Shareholders’ Meetings, YPF will directly own 100% of the shares of the Absorbed Companies—and as set forth in Exhibit II to the Preliminary Merger Agreement (Exhibit A)—the capital stock will not be increased and, consequently, no new shares of YPF will be issued in connection with the absorption of the Absorbed Companies by the Absorbing Company. Accordingly, no exchange ratio will be established as a result of the Merger..

4. No Amendment to the corporate by-laws of YPF required

As a result of the Merger, and as indicated in paragraph 3 above, the capital stock of YPF will not be modified.

Besides, the Corporate By-Laws of YPF will not be amended as YPF’s corporate purpose allows it to undertake the activities carried out by the Absorbed Companies.

5. Effective date of reorganization

Under the Preliminary Merger Agreement, as from January 1, 2026, 100% of all assets (including real and personal property, patents, trademarks, receivables and intangibles), liabilities, rights and obligations of the Absorbed Companies shall be deemed incorporated into the assets of YPF for all purposes, including accounting and tax purposes, without any reservations or limitations whatsoever.

Under the provisions of Sections 82 and related sections of the LGS, YPF shall acquire title to all rights and obligations of the Absorbed Companies, and the transfer of their respective assets and liabilities shall become effective upon registration of the Definite Merger Agreement with the IGJ, with effect as from January 1, 2026.

6. Public offering of securities

YPF is authorized to make public offerings of its securities on the CNV and the SEC. Its securities are traded on the BYMA and the NYSE.

YPF is subject to the supervision of the CNV, and, therefore, is also subject to the provisions of Chapter X, Title II of the CNV Regulations and the regulations of the markets in which its securities are traded.

The Absorbed Companies are not admitted to the securities public offering system and their shares are not traded in any local or foreign stock exchange.

7.  Extraordinary General Shareholders’ Meetings of YPF, YPF VENTURES and OLCLP

The Extraordinary Shareholders’ Meetings of YPF, YPF VENTURES and OLCLP shall be held on April 30, 2026, within the statutory period to consider, among other issues, the Merger and the respective Preliminary Merger Agreement, the Special-Purpose Merger Financial Statements as of December 31, 2025, the Consolidated Merger Balance Sheet and the dissolution without liquidation of the Absorbed Companies, as appropriate.

Such Extraordinary Shareholders’ Meetings were called by the respective Boards of  Directors of the Merging Companies, whose meetings were held on the following dates:

         YPF: by Board of Directors’ meeting of March 27, 2026

         YPF VENTURES: by Board of Directors’ Meeting of April 6, 2026

         OLCLP: by Board of Directors’ meeting of April 6, 2026

Once such Extraordinary Shareholders’ Meetings have been called and held, the Merging Companies shall publish a notice of merger for 3 (three) days in accordance with the provisions of section 83, subsection 3) of the LGS. Such notice shall include, among other information, the value of the assets and liabilities to be transferred, the execution date of the Preliminary Merger Agreement and the dates of the corporate resolutions approving it. Creditors of the Merging Companies may file objections to the Merger within a term of fifteen (15) days from the last publication of such notice. Any creditors objecting to the Merger will have twenty (20) additional days upon the expiration of the said 15-day term to obtain a warrant of attachment from a court in those cases in which they have not been paid off or properly secured.

Upon the expiration of the terms mentioned above, the representatives of the Merging Companies shall execute the Definitive Merger Agreement (the "Definitive Merger Agreement") before a notary public and shall file it with the CNV and the relevant regulatory authorities to obtain the approval and subsequent registration of the Merger and dissolution without liquidation of the Absorbed Companies. Once the Definitive Merger Agreement has been approved and registered with the IGJ, the Merger shall be binding upon and enforceable against third parties.

8. Management of the Absorbed Companies

The Parties agree not to impose limitations on the management of their respective activities and not to grant any warranties from the Effective Date of the Merger until the Merger is effectively registered for the regular performance of their operations. From the date of the Definitive Merger Agreement -and unless the competent authorities provide otherwise- the management and representation of the Absorbed Companies shall be performed by the Board of Directors and President (respectively) of YPF, and the officers previously exercising such functions in the Absorbed Companies shall cease in such roles (section 84, last paragraph, of the LGS). From the Effective Date of Merger until the registration of the Definitive Merger Agreement with the IGJ, all acts performed and carried out by the Absorbed Companies as a result of the management of the businesses to be merged shall be considered as carried out on behalf of YPF. YPF shall conduct its business in such a way so as to avoid any acts that might lead to material changes in the composition of the merged equities until the registration of the Definitive Merger Agreement with the IGJ.

9. Administrative approvals, authorizations and consents

It is hereby placed on record that this Merger does not require any prior notice or review by the Argentine Antitrust Commission (Comisión Nacional de Defensa de la Competencia), as it is an intragroup reorganization and, therefore, there has been no “change of control” as defined in section 7 and related sections of Law No. 27,442. Besides, this Merger does not require any other administrative consent.

REASONS AND PURPOSES OF THE MERGER

The Merger is carried out with the purpose of improving administrative efficiency, reducing and rationalizing operating costs, and generating administrative and tax savings, as well as simplifying the corporate structure and optimizing the technical, administrative and financial structures of the companies involved. Accordingly, it is deemed advisable to centralize business management within a single corporate entity in order to manage the activities of the participating companies in a uniform and coordinated manner, thereby achieving proper planning, reducing costs and optimizing resources.

CORPORATE RESOLUTIONS APPROVING THE MERGER

The Preliminary Merger Agreement, the respective Special-Purpose Merger Financial Statements as of December 31, 2025 and the Consolidated Merger Balance Sheet of the Merging Companies were approved by the respective Board of Directors of each of the Merging Companies on March 13, 2026.

Under the Preliminary Merger Agreement, the Merging Companies agreed that (i) the Merger must be approved by the Extraordinary Shareholders’ Meetings, for which purpose the parties agreed to submit to the consideration of their respective Boards of Directors, the approval of the Preliminary Merger Agreement, the authorization for the execution of the Definitive Merger Agreement and the dissolution without liquidation of the Absorbed Companies, as applicable, among other issues; and (ii) should the Extraordinary Shareholders’ Meeting of the Absorbing Company, or the Extraordinary Shareholders’ Meeting of the Absorbed Companies fail to approve it, the Preliminary Merger Agreement shall be null and void.

ACCOUNTING INFORMATION

In compliance with the provisions of Section 83 of the LGS, Section 146, subsection 3 of IGJ General Resolution No. 15/2024, Section 3, subsection 6, Part I, Chapter X, Title II of the CNV Regulations, and Section 104, subsection 4, Chapter IX, Title II of the ByMA Regulations, as well as any other applicable legal and regulatory provisions, the Merging Companies have prepared a Consolidated Merger Balance Sheet based on consistent and identical valuation criteria in compliance with the IFRS, since the Absorbing Company is admitted to the securities public offering system, and, therefore, it is required to prepare its financial statements in accordance with the IFRS. Such Consolidated Merger Balance Sheet has been prepared based on the information reported in the Special-Purpose Merger Financial Statements as of December 31, 2025 of each of the Merging Companies, all of which have been audited by Deloitte & Co. S.A., including, where applicable, presentation and measurement adjustments to align such information with IFRS.

As set forth in Section 7 of the Preliminary Merger Agreement, in light of the fact that, as of the date of the Extraordinary Shareholders’ Meetings, YPF directly owns 100% of the shares of YPF VENTURES and OLCLP, the capital stock of YPF will not be increased and no new shares will be issued as a result of the Merger; accordingly, no exchange ratio shall apply.
