TABLE OF CONTENTS

CONSOLIDATED RESULTS

The main functional currency of the Petrobras Group (the “Company”) is the Brazilian real, which is the functional currency of the parent company and its Brazilian subsidiaries. As the presentation currency of the Petrobras Group is the U.S. dollar, the results of operations in Brazilian reais are translated into U.S. dollars using the average exchange rates prevailing on a monthly basis.

Key Financial Information

Sales Revenues

Sales revenues were US$ 42,110 million for the period Jan-Jun/2025, a 10.9% decrease (US$ 5,125 million) when compared to US$ 47,235 million for the period Jan-Jun/2024, mainly due to:

Cost of Sales

Cost of sales was US$ 21,710 million for the period Jan-Jun/2025, a 6.6% decrease (US$ 1,541 million) when compared to US$ 23,251 million for the period Jan-Jun/2024, mainly due to a US$ 867 million decrease in crude oil imports, which derives from a US$ 965 million decrease in import volumes, which was partially offset by a US$ 98 million increase in average oil products import prices.

Income (Expenses)

Selling expenses were US$ 2,376 million for the period Jan-Jun/2025, an 8.7% decrease (US$ 225 million) compared to US$ 2,601 million for the period Jan-Jun/2024, mainly due to lower logistical expenses related to lower volumes of crude oil exports.

Exploration costs were US$ 498 million for the period Jan-Jun/2025, a 61.2% increase (US$ 189 million) compared to US$ 309 million for the period Jan-Jun/2024, mainly due to exploration expenditures written off related to blocks C-M-753 and C-M-789 in the Campos Basin, reflecting the assessment of the projects' lack of economic feasibility, which resulted in the decision not to proceed with their development.

Other taxes were US$ 250 million for the period Jan-Jun/2025, a 77.0% decrease (US$ 838 million) compared to US$ 1,088 million for the period Jan-Jun/2024, mainly due to enrollment to the tax settlement program in Jun/24, which allowed the settlement of significant legal disputes related to discussions on the incidence of taxes on remittances abroad involving chartering of vessels or platforms and their respective service contracts.

Net finance income (expense)

Net finance income (expense) was an income of US$ 2,763 million for the period Jan-Jun/2025, an increase of US$ 11,571 million compared to an expense of US$ 8,808 million for the period Jan-Jun/2024, mainly due to a foreign exchange gain - Real x U.S. dollar of US$ 5,218 million in Jan-Jun/2025, as compared to a US$ 4,449 million loss in Jan-Jun/2024 reflecting a 11.8% appreciation of the real/US$ exchange rate in Jan-Jun/2025 (06/30/2025: R$ 5.46/US$, 12/31/2024: R$ 6.19/US$) compared to a 14.9% depreciation in Jan-Jun/2024 (06/30/2024: R$ 5.56/US$, 12/31/2023: R$ 4.84/US$).

Income taxes

Income tax was an expense of US$ 4,765 million in Jan-Jun/2025, compared to an expense of US$ 2,120 million in Jan-Jun/2024. The increase was mainly due to higher net income before income taxes (US$ 15,517 million of income in Jan-Jun/2025 compared to a US$ 6,600 million income in Jan-Jun/2024), resulting in nominal income taxes computed based on Brazilian statutory corporate tax rates (34%) of US$ 5,275 million in Jan-Jun/2025 compared to a US$ 2,243 million in Jan-Jun/2024.

Net Income attributable to shareholders of Petrobras

Net income attributable to shareholders of Petrobras was US$ 10,708 million for the period Jan-Jun/2025, a US$ 6,270 million increase compared to a net income attributable to shareholders of Petrobras of US$ 4,438 million for the period Jan-Jun/2024, as explained above, mainly due to higher net finance income (US$ 2,763 million of income in Jan-Jun/2025 compared to US$ 8,808 million of expenses in Jan-Jun/2024) and lower expenses (US$ 7,775 million of expenses in Jan-Jun/2025 compared to US$ 8,295 million of expenses in Jan-Jun/2024), partially offset by lower gross profit (US$ 20,400 million in Jan-Jun/2025 compared to US$ 23,984 million in Jan-Jun/2024) and higher income taxes expenses (US$ 4,765 million of expenses in Jan-Jun/2025 compared to US$ 2,120 million of expenses in Jan-Jun/2024).

CAPITAL EXPENDITURES (CAPEX)

In line with our Business Plan, our Capital Expenditures were primarily directed toward investment projects which Management believes are most profitable, relating to oil and gas production.

In Jan-Jun/2025, Capital Expenditures in the E&P segment totaled US$ 7,224 million, representing 85.0% of the CAPEX of the Company, a 37.9% increase when compared to US$ 5,239 million in Jan-Jun/2024, mainly due to the development of large projects in the pre-salt layer of the Santos Basin, especially in the Búzios and Atapu Fields. CAPEX in Jan-Jun/2025 were mainly concentrated on: (i) the development of production in the pre-salt layer of the Santos Basin (US$ 3.7 billion); (ii) the development of production in the pre-salt and post-salt layers of the Campos Basin (US$ 1.5 billion); and (iii) exploratory investments (US$ 0.8 billion).

LIQUIDITY AND CAPITAL RESOURCES

(1) Free Cash Flow (FCF) is in accordance with the new Shareholder Remuneration Policy (“Policy”), approved in July 2023, which is the result of the equation: FCF = net cash provided by operating activities less the sum of acquisition of PP&E and intangible assets and acquisition of equity interests.

As of June 30, 2025, Cash and cash equivalents amounted to US$ 6,996 million and Adjusted Cash and Cash Equivalents totaled US$ 9,501 million.

In the six-month period ended June 30, 2025, we had net cash provided by operating activities of US$ 16,029 million and positive Free Cash Flow of US$ 7,981 million. This level of cash generation, together with proceeds from disposal of assets (divestments) of US$ 479 million, financial compensation from co-participation agreements of US$ 355 million, dividends received of US$ 25 million, divestment in marketable securities of US$ 2,861 million and proceeds from finance debt of US$ 3,072 million, were allocated to: (a) debt prepayments and payments of principal and interest due in the period of US$ 2,403 million; (b) repayment of lease liability of US$ 4,368 million; (c) dividends paid to shareholders of Petrobras of US$ 4,588 million; and (d) acquisition of PP&E and intangibles assets of US$ 8,046 million.

In the six-month period ended June 30, 2025, the Company repaid several finance debts, in the amount of US$ 2,403 million.

In the six-month period ended June 30, 2025, the Company raised US$ 3,072 million, notably from: (i) public offering of debentures, in the amount of USS$ 516 million, with maturities in 2035, 2040, and 2045; (ii) proceeds in the domestic banking market, in the amount of US$ 1,417 million; and (iii) proceeds in the international banking market, in the amount of US$ 1,122 million.

CONSOLIDATED DEBT

As of June 30, 2025, the Company has maintained its liability management strategy to improve the debt profile and to adapt to the maturity terms of the Company’s long-term investments.

Gross Debt increased 12.9% (US$ 7,753 million) to US$ 68,064 million as of June 30, 2025 from US$ 60,311 million as of December 31, 2024, due to: (i) higher lease liabilities in the period (a US$ 5,124 million increase), primarily driven by the start-up of the leased FPSO Alexandre de Gusmão (Mero 4), the start-up of the leased FPSO Almirante Tamandaré (Búzios 7) and the extension of the FPSO Cidade de Angra dos Reis agreement through 2030; and to (ii) higher finance debt (a US$ 2,629 million increase), mainly due to the proceeds in the domestic banking market, in the amount of US$ 1,417 million, and proceeds in the international banking market, in the amount of US$ 1,122 million. Gross Debt was maintained lower than the maximum level of US$ 75,000 million, with convergence to the level of US$ 65,000 million defined in the 2025-2029 Business Plan, mainly due to debt prepayments and scheduled repayments.

As of June 30, 2025, Net Debt increased by 12.1% (US$ 6,323 million), reaching US$ 58,563 million, compared to US$ 52,240 million as of December 31, 2024, mainly due to a US$ 5,124 million increase in lease liabilities in the period.

RECONCILIATION OF ADJUSTED EBITDA, LTM ADJUSTED EBITDA AND NET DEBT/LTM ADJUSTED EBITDA METRICS

LTM Adjusted EBITDA reflects the sum of the last twelve months of Adjusted EBITDA, which is computed by using the net income before net finance income (expense), income taxes, depreciation, depletion and amortization adjusted by items not considered part of the Company’s primary business, which include results in equity-accounted investments, results on disposal and write-offs of assets, impairment and results from co-participation agreements in bid areas.

LTM Adjusted EBITDA represents an alternative to the Company's operating cash generation. This measure is used to calculate the metric Net Debt/LTM Adjusted EBITDA, to support management’s assessment of liquidity and leverage.

Adjusted EBITDA and Net cash provided by operating activities – OCF

LTM Adjusted EBITDA and LTM Net cash provided by operating activities – OCF

Adjusted Cash and Cash Equivalents, Gross Debt, Net Debt, Net Cash provided by Operating Activities (LTM OCF), LTM Adjusted EBITDA, Gross Debt Net of Cash and Cash Equivalents/LTM OCF and Net Debt/LTM Adjusted EBITDA Metrics

The Net Debt/LTM Adjusted EBITDA metric is an important metric that supports our management in assessing the liquidity and leverage of Petrobras Group. This ratio is an important measure for management to assess the Company’s ability to pay off its debt, mainly because our Business Plan 2025-2029 defines US$ 75 billion as the maximum level for our Gross Debt, with convergence to the level of US$ 65 billion.

The following table presents the reconciliation of these metrics to the most directly comparable measures derived from the IFRS Accounting Standards captions:

RESULTS BY OPERATING BUSINESS SEGMENTS

Exploration and Production (E&P)

Financial information

^[1]

In the period Jan-Jun/2025, the gross profit for the E&P segment was US$ 16,073 million, a decrease of 15.0% compared to the period Jan-Jun/2024, mainly due to the reduction in sales revenues which reflect lower Brent prices, partially offset by increased crude oil and NGL production during the period.

Operating income was US$ 13,489 million in the Jan-Jun/2025 period, a decrease of 19.3% compared to the period Jan-Jun/2024, mainly driven by increased expenses resulting from the provision for the equalization of expenditures and volumes related to the approval of the Jubarte Production Individualization Agreement, higher exploration expenditures write-offs related to blocks C-M-753 and C-M-789 in the Campos Basin, in addition to higher impairment losses mainly due to the Uruguá CGU and Cherne Cluster, partially offset by lower tax expenses in comparison to the period Jan-Jun/2024.

In the period Jan-Jun/2025, the production taxes were US$ 5,354 million, a decrease of 9.7% compared to the period from Jan-Jun/2024 caused primarily by the lower prices.

Operational information

Production of crude oil, NGL and natural gas was 2,839 mboed in the period Jan-Jun/2025, representing an increase of 3.7% compared to Jan-Jun/2024, mainly due to the ramp-up of: (i) the FPSO Almirante Tamandaré in the Búzios field, (ii) the FPSOs Sepetiba and Marechal Duque de Caxias, both in Mero field, (iii) the FPSO Maria Quitéria in the Jubarte field, (iv) and the FPSO Anita Garibaldi in Marlim and Voador fields; in addition to the start-up of production: (v) at the FPSO Alexandre de Gusmão in Mero field, and (vi) of new wells from complementary projects in the Campos and Santos Basins; (vii) lower volumes of losses due to maintenance shutdowns; and (viii) higher operational efficiency in Santos Basin. These factors were partially offset by declining potential in mature fields and lower operational efficiency in the Campos Basin.

Refining, Transportation and Marketing

Financial information

In the period Jan-Jun/2025, Refining, Transportation and Marketing gross profit was US$ 1,291 million lower than in the period Jan-Jun/2024 mainly due to a decrease in international margins, especially diesel, gasoline and jet fuel.

The decrease in operating income for the period Jan-Jun/2025 reflects the reduction in gross profit and higher expenses in maintenance stoppages in Jan-Jun/2025 when compared with Jan-Jun/24.

The average refining cost in the period Jan-Jun/2025 was US$ 2.79/bbl, 6.1% higher than in the period Jan-Jun/2024, mainly due to an increase in maintenance costs and revitalization activities in our refineries, partially offset by a relatively devalued local currency in 2025 reducing the costs in U.S. dollar terms.

Operational information

(1) Changes presented in percentage points.

Domestic sales in the period Jan-Jun/2025 were 1,705 mbbl/d, an increase of 1.9% compared to the period Jan-Jun/2024.

Gasoline sales volume increased 3.1% in Jan-Jun/2025 compared to Jan-Jun/2024 mainly due to the increase in total demand for Otto cycle fuels and a higher share of gasoline compared to ethanol. Diesel sales volume increased 3.3% between periods, mainly influenced by a decrease in imports by third parties.

Total oil products output for the period Jan-Jun/2025 was 1,718 mbbl/d, representing a 1.7% decrease compared to Jan-Jun/2024. In the first half of 2025 the utilization factor of our refineries remained aligned with the same period of the previous year, considering the resumption of operations at the Abreu e Lima Refinery, located in northeastern Brazil, following the completion of its scheduled turnaround in the first quarter of 2025.

Gas and Low Carbon Energies 

Financial information

In Jan-Jun/2025, the sales revenues reduction in relation to Jan-Jun/2024 was due to the lower average natural gas sales price due to the drop in the Brent price, the lower volume of natural gas sold to non-thermoelectric segment, the entry of new agents in this market and the expiration of thermal availability contracts.

The lower operating income in Jan-Jun/2025 compared to Jan-Jun/2024 is mainly due to the lower gross profit despite lower expenses.

Operational information

In Jan-Jun/2025, Petrobras thermal availability sales decreased by 39.8% compared to Jan-Jun/2024, due to the expiration of contracts. In the same period, energy sales increased by 60.2% due to a less favorable hydrological scenario and through the capture of opportunities with spot prices.

On the natural gas supply side, domestic gas production in Jan-Jun/2025 grew 6.7% due to availability of gas from the Rota 3 gas pipeline and the operation of the Itaborai gas processing unit. As a result of lower demand, there was a decrease in natural gas imports.

Adjusted EBITDA Net income plus net finance income (expense); income taxes; depreciation, depletion and amortization; results in equity-accounted investments; impairment; results on disposal/write-offs of assets; and results from co-participation agreements in bid areas. Adjusted EBITDA is not a measure defined by the IFRS Accounting Standards and it is possible that it may not be comparable to similar measures reported by other companies. However, management believes that it is an appropriate supplemental measure to assess our liquidity and supports leverage management.

Free Cash Flow - Net cash provided by operating activities less the sum of acquisition of PP&E and intangibles assets and acquisition of equity interests. Free cash flow is not defined under the IFRS Accounting Standards and should not be considered in isolation or as a substitute for cash and cash equivalents calculated in accordance with IFRS Accounting Standards. It may not be comparable to free cash flow of other companies. However, management believes that it is an appropriate supplemental measure to assess our liquidity and supports leverage management.

Gross Debt – Sum of current and non-current finance debt and lease liability, this measure is not defined under the IFRS Accounting Standards.

Leverage – Ratio between the Net Debt and the sum of Net Debt and Market Capitalization. Leverage is not a measure defined in the IFRS Accounting Standards and it is possible that it may not be comparable to similar measures reported by other companies, however management believes that it is an appropriate supplemental measure to assess our liquidity.

Lifting Cost - Crude oil and natural gas lifting cost indicator, which considers expenditures occurred in the period.

Results by Business Segment – The information by the company's business segment is prepared based on available financial information that is directly attributable to the segment or that can be allocated on a reasonable basis, being presented by business activities used by the Executive Board to make resource allocation decisions and performance evaluation.

When calculating segmented results, transactions with third parties, including jointly controlled and associated companies, and transfers between business segments are considered. Transactions between business segments are valued at internal transfer prices calculated based on methodologies that take into account market parameters, and these transactions are eliminated, outside the business segments, for the purpose of reconciling the segmented information with the consolidated financial statements of the company.
