INDEPENDENT AUDITOR’S REPORT ON

REVIEW OF INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

To the President and Directors of YPF SOCIEDAD ANONIMA

1. Identification of the interim condensed consolidated financial statements subject to review

We have reviewed the accompanying interim condensed consolidated financial statements of YPF SOCIEDAD ANONIMA (the Company) and its controlled companies (the Group), which comprise the consolidated interim condensed statement of financial position as at September 2025, the interim condensed consolidated statements of comprehensive income, changes in equity and cash flows for the nine months period as at September 2025, and other explanatory information included in the notes 1 to 39 to the interim condensed consolidated financial statements.

2. Responsibilities of the Company’s Board of Directors for the interim condensed consolidated financial statements

The Company’s Board of Directors is responsible for the preparation and fair presentation of the accompanying interim condensed consolidated financial statements in accordance with IFRS Accounting Standards, as issued by the International Accounting Standards Board (IASB), and consequently, is responsible for the preparation and fair presentation of these interim condensed financial statements in accordance with International Accounting Standard 34, “Interim financial reporting” (IAS 34). Additionally, the Company’s Board of Directors is responsible for such internal control as the Board determines is necessary to enable the preparation of financial statements that are free from material misstatements.

3. Auditors’ responsibilities

Our responsibility is to express a conclusion on the accompanying interim condensed consolidated financial statements based on our review. We conducted our review in accordance with the International Standards for Review Engagements (ISRE) 2410, “Review of Interim Financial Information Performed by the Independent Auditor of the Entity” issued by the International Auditing and Assurance Standards Board (IAASB).

A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing (ISA) and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

4. Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying interim condensed consolidated financial statements of YPF SOCIEDAD ANONIMA for the nine-month period ended September 2025 are not prepared, in all material respects, in accordance with IAS 34.

5. Other Matter

The accompanying interim condensed consolidated financial statements are prepared and presented in U.S. dollars, which is the functional currency of the Company. The interim condensed consolidated financial statements used by Company for statutory, legal and regulatory purposes in Argentina are those issued and filed with the Argentine Securities Commission (Comisión Nacional de Valores) and approved by the Company’s Board of Directors and authorized for issuance on November 7, 2025.

==> picture [62 x 26] intentionally omitted <==

(Amounts expressed in millions of United States dollars, except for shares and per share amounts expressed in United States dollars, or as otherwise indicated)

1. GENERAL INFORMATION, STRUCTURE AND ORGANIZATION OF THE GROUP’S BUSINESS (cont.)

Organization of the business

As of September 30, 2025, the Group carries out its operations in accordance with the following structure:

• Upstream

• Midstream and Downstream

• LNG and Integrated Gas

• New Energies

• Central Administration and Others

Activities covered by each business segment are detailed in Note 6.

The operations, properties and clients of the Group are mainly located in Argentina. However, the Group also holds participating interest in exploratory areas in Bolivia and sells natural gas, lubricants and derivatives in Chile.

2. BASIS OF PREPARATION OF THE CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

2.a) Applicable accounting framework

The condensed interim consolidated financial statements of the Company for the nine-month period ended September 30, 2025, are presented in accordance with IAS 34 “Interim financial reporting”. Therefore, they should be read together with the annual consolidated financial statements of the Company as of December 31, 2024 (“annual consolidated financial statements”) presented in U.S. dollars and in accordance with IFRS Accounting Standards as issued by the IASB.

These condensed interim consolidated financial statements corresponding to the nine-month period ended September 30, 2025, are unaudited. The Company believes they include all necessary adjustments to reasonably present the results of each period on a basis consistent with the audited annual consolidated financial statements. Net Income for the ninemonth period ended September 30, 2025 does not necessarily reflect the proportion of the Group’s full-year net income.

2.b) Material accounting policies

The material accounting policies are described in Note 2.b) to the annual consolidated financial statements.

The accounting policies adopted in the preparation of these condensed interim consolidated financial statements are consistent with those used in the preparation of the annual consolidated financial statements, except for the valuation policy for income tax described in Note 19 and the change in the presentation of exchange differences generated by deferred tax described in Note 2.d).

Functional currency

As mentioned in Note 2.b.1) to the annual consolidated financial statements, YPF has defined the U.S. dollar as its functional currency.

The consolidated financial statements used by YPF for statutory, legal and regulatory purposes in Argentina are those in pesos and filed with the CNV and approved by the Board of Directors and authorized to be issued on November 7, 2025.

Business combinations

The Group analyzes whether the assets acquired and liabilities assumed in a purchase transaction qualify as a business combination in accordance with IFRS 3 “Business combinations”. Business combinations are accounted for using the acquisition method, which requires, among others, the recognition and measurement at fair value of the identifiable assets acquired, the liabilities assumed and any non-controlling interest. The excess of the consideration transferred over such fair value is recognized as goodwill and the shortfall as a gain in profit or loss for the period.

When the assets acquired are not a business, the Group accounts for the transaction as the acquisition of an asset.

(Amounts expressed in millions of United States dollars, except for shares and per share amounts expressed in United States dollars, or as otherwise indicated)

2. BASIS OF PREPARATION OF THE CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (cont.)

Adoption of new standards and interpretations effective as from January 1, 2025

The Company has adopted all new and revised standards and interpretations issued by the IASB, relevant to its operations which are of mandatory and effective application as of September 30, 2025, as described in Note 2.b.14) to the annual consolidated financial statements.

The adoption of the amendments mentioned in Note 2.b.14) “Amendments to IAS 21 - Lack of exchangeability” section to the annual consolidated financial statements has not had a significant effect on these condensed interim consolidated financial statements.

Standards and interpretations issued by the IASB whose application is not mandatory at the closing date of these condensed interim consolidated financial statements and have not been adopted by the Group

In accordance with Article 1, Chapter III, Title IV of the CNV rules, the early application of the IFRS and/or their amendments is not permitted for issuers filing financial statements with the CNV, unless specifically admitted by such agency.

2.c) Significant estimates and key sources of estimation uncertainty

In preparing the financial statements at a certain date, the Group is required to make estimates and assessments affecting the amount of assets and liabilities recorded and the contingent assets and liabilities disclosed at such date, as well as income and expenses recognized in the fiscal year or period. Actual future profit or loss might differ from the estimates and assessments made at the date of preparation of these condensed interim consolidated financial statements.

The assumptions relating to the future and other key sources of uncertainty about the estimates made for the preparation of these condensed interim consolidated financial statements are consistent with those used by the Group in the preparation of the annual consolidated financial statements, which are disclosed in Note 2.c) to the annual consolidated financial statements.

2.d) Comparative information

Amounts and other financial information corresponding to the fiscal year ended December 31, 2024 and for the nine-month period ended September 30, 2024 are an integral part of these condensed interim consolidated financial statements and are intended to be read only in relation to these financial statements. Likewise, changes have been made to the comparative figures in Notes 6 and 26 as mentioned in Note 6.

Additionally, the Group has changed the presentation of exchange differences generated by deferred tax classifying these items as deferred tax expense (income) in accordance with IAS 12 “Income taxes”. Previously, these exchange differences were presented in the “Other exchange differences, net” line item under “Other financial results” in the statement of comprehensive income and, from this period, they are presented in the “Income tax” line item in the statement of comprehensive income (see Note 19). The purpose of this change is to provide more useful information and improve the comparability of the Group's financial statements with its peers. The comparative information has been restated by reclassifying a gain of 170 and 47 from “Other financial results” line item to “Income tax” line item in the statement of comprehensive income for the nine and three-month periods ended September 30, 2024, respectively. This change had no effect on the Group’s statements of financial position, statements of changes in shareholders’ equity, cash flows, operating profit or loss and net profit or loss.

3. SEASONALITY OF OPERATIONS

Historically, the Group’s results have been subject to seasonal fluctuations throughout the year, particularly as a result of the increase in natural gas sales during the winter driven by the increased demand in the residential segment. Consequently, the Group is subject to seasonal fluctuations in its sales volumes and prices, with higher sales of natural gas during the winter at higher prices.

On January 29, 2025 (“acquisition date”), after the fulfillment of the closing conditions, the sale and transfer by the Sellers to YPF of 100% of MASA's shares and capital stock was completed. The amount of the transaction was 327 in cash. As of the acquisition date, MASA will continue to operate under the corporate name SC Gas S.A.U. (“SC Gas”), being YPF its sole shareholder.

The transaction described above qualifies as a business combination in accordance with IFRS 3 and is accounted for using the acquisition method (see Note 2.b) “Business combinations” section).

Based on the closing of the aforementioned share purchase and sale agreement and considering the fair value of the assets and liabilities of YPF Brasil classified as held for sale, as of the closing date of the transaction, the result from the sale did not have significant effects. In addition, the translation differences accumulated in the “Other comprehensive income” account and reclassified to the profit or loss due to the loss of control of the subsidiary amounted to a loss of 9.

Additionally, as of the issuance date of these condensed interim consolidated financial statements, the reversion agreement is subject to the approval by decree of the Executive Branch of the Province of Chubut.

As of the date of issuance of these condensed interim consolidated financial statements, the Company has signed assignment agreements for certain groups of assets as held for sale that are subject to closing conditions mainly related to regulatory and provincial approvals, for which the Company is taking the necessary steps to close; and it is highly probable that these assets will be disposed. In addition, the Company maintains groups of assets as held for sale for which agreements have not yet been signed but continues in negotiations with third parties for their disposal or reversal. The delay in the fulfillment of the plan for the disposal of mature fields is due to the complexity of the negotiations, which is beyond the Company’s control. As of the date of issuance of these condensed interim consolidated financial statements, the Company considers that the disposal of such assets continues to be highly probable during 2025.

• Accounting matters

Considering that the assets classified as held for sale are measured at the lower of their carrying amount and fair value less costs to sell (“fair value”), the Company evaluates the changes in fair value, recognizing a profit up to the limit of the impairment loss previously recognized or an impairment loss in addition to that previously recognized for such changes, (see Note 2.b.13) to the annual consolidated financial statements). The carrying amount of the assets held for sale and associated liabilities may be adjusted in future periods depending on the results of the disposal process carry out by YPF and the economic consideration to be agreed with third parties for such assets.

Provisions are described in Note 17 to the annual consolidated financial statements. Updates for the nine-month period ended September 30, 2025, are described below:

Regarding the legal proceedings related to liabilities and contingencies assumed by the Argentine Government prior to 1990 mentioned in the Note 17.a.1) to the annual consolidated financial statement, on September 2, 2025, the CSJN issued an order in which it considered that YPF lacked standing as a defendant, as it had no legal relationship with respect to claims for environmental liabilities not assumed by YPF and assumed by the Argentine Government under the terms of the YPF’s Privatization Law.

19. INCOME TAX

According to IAS 34, income tax expense is recognized in each interim period based on the best estimate of the effective income tax rate expected as of the closing date of these condensed interim consolidated financial statements, considering the tax criteria that the Group assumes to apply during the fiscal year.

(Amounts expressed in millions of United States dollars, except for shares and per share amounts expressed in United States dollars, or as otherwise indicated)

19. INCOME TAX (cont.)

The effective income tax rate projected at the end of the fiscal year amounts to 129.01%. The variation in this rate compared to the effective rate as of December 31, 2024 (see Note 18 to the annual consolidated financial statements) is mainly explained by the impact of the estimation of certain macroeconomic variables in the measurement of property, plant, and equipment for accounting and tax purposes, which generates an increase in deferred income tax liability related to those assets. The accounting measurement of property, plant and equipment is based on the Company's functional currency according to IFRS (see Note 2.b)), while the tax measurement is based on inflation-adjusted pesos.

As of September 30, 2025 and December 31, 2024, the causes that generated charges within “Other comprehensive income” line item in the statement of comprehensive income did not generate temporary differences subject to income tax.

As of September 30, 2025 and December 31, 2024 the Group has classified as deferred tax asset 4 and 330, respectively, and as deferred tax liability 389 and 90, respectively, all of which arise from the net deferred tax balances of each of the individual companies included in these condensed interim consolidated financial statements.

34.b.1) Contentious claims

• Petersen Energía Inversora, S.A.U. and Petersen Energía, S.A.U. (collectively, “Petersen”) – Eton Park Capital Management, L.P., Eton Park Master Fund, LTD. and Eton Park Fund, L.P. (collectively, “Eton Park”, and together with Petersen, the “Plaintiffs”)

On June 30, 2025, the District Court granted Plaintiffs’ turnover motion, ordering the Republic to: (i) transfer its Class D shares of YPF to a global custody account at the Bank of New York Mellon (“BNYM”) in New York within 14 days of the date of the order; and (ii) instruct BNYM to initiate a transfer of the Republic’s ownership interests in its Class D shares of YPF to Plaintiffs or their designees within one business day of the date on which the shares are deposited into the account.

Also on June 30, 2025, in proceedings brought by Bainbridge Fund Ltd. against the Republic, the District Court issued a similar order directing the Republic to turn over its Class A and Class D shares of YPF.

The Republic filed motions to stay the June 30, 2025 turnover orders pending its appeal of those orders, which were denied by the District Court.

On July 10, 2025, the Republic filed with the Court of Appeals: (i) notices of appeal of the June 30, 2025 turnover orders in both Plaintiffs’ and Bainbridge Fund Ltd.’s proceedings; and (ii) emergency motions for a stay pending appeal of the June 30, 2025 turnover orders and an immediate administrative stay. On July 15, 2025, the Court of Appeals granted a temporary administrative stay of the turnover orders pending resolution of the stay motions. On August 15, 2025, the Court of Appeals granted a stay pending resolution of the Republic’s appeal of the June 30, 2025 turnover orders.

YPF is not a party to the aforementioned turnover proceedings.

It should be noted that the District Court’s decision does not decide the question of whether YPF is an alter ego of the Republic, which YPF strongly denies.

On October 1, 2025, YPF filed a motion for reconsideration of the September 17, 2025 order with the District Court, as well as a pre-motion letter requesting to stay discovery from YPF. On October 6, 2025, Plaintiffs submitted a letter opposing a discovery stay and YPF replied on October 7, 2025. On October 15, 2025, Plaintiffs filed an opposition to YPF’s motion for reconsideration. On October 16, 2025, the District Court held a conference regarding YPF’s request to stay alter ego discovery from YPF. The Court granted the request for a stay pending resolution of YPF’s reconsideration motion. On October 17, 2025, YPF filed its notice of appeal of the September 17, 2025 order. On October 22, 2025, YPF filed its reply to Plaintiffs’ opposition of October 15, 2025.
