Dividends relating to 2025

On April 16, 2026, the Annual General Shareholders Meeting approved dividends relating to 2025, amounting to US$ 7,507 (US$ 0.5814 per outstanding share). This amount includes US$ 6,040 anticipated during 2025 (updated by Selic interest rate from the date of each payment to December 31, 2025) and US$ 1,467 of complementary dividends which are accounted for as additional dividends proposed.

These complementary dividends were reclassified from equity to liabilities on the date of approval at the Annual General Shareholders Meeting and were paid in 2 installments in May and June 2026, in the form of interest on capital, updated by the Selic interest rate from December 31, 2025 to the date of each payment.

This payment of interest on capital resulted in a deductible expense which reduced the income tax expense by US$ 545. Interest on capital is subject to withholding income tax (IRRF), except for immune and exempt shareholders, as established in applicable law. The tax benefit related to the complementary dividends was recognized in the second quarter of 2026.

On November 27, 2025, law No. 15,270/2025 was published, establishing the withholding income tax at a 10% rate on dividends distributed to individuals domiciled in Brazil, when such dividends exceed R$ 50 thousand per month. The 10% rate also applies to dividends distributed abroad to individuals or legal entities, regardless of the amount, except in specific situations provided for by law.  In addition, supplementary law No. 224/2025 increased the withholding income tax rate applicable to interest on capital from 15% to 17.5%. Both laws are effective as of January 1, 2026.

Interest on capital relating to the first quarter of 2026

On May 11, 2026, Petrobras’s Board of Directors approved the distribution of remuneration to shareholders in the amount of US$ 1,845 or R$ 9,034 million (US$ 0.1431 per outstanding common and preferred shares, or R$ 0.7010), based on the net income for the three-month period ended March 31, 2026, considering the application of the Shareholder Remuneration Policy formula, as presented in the following table:

This interest on capital will be paid in two equal installments, on August 20 and September 21, 2026, and will be offset against shareholder renumeration relating to 2026. The amounts will be adjusted by the SELIC rate from the date of payment of each installment until the end of this fiscal year.

This anticipation of interest on capital generated a tax-deductible expense resulting in a reduction of income tax expense by US$ 617. Interest on capital is subject to withholding income tax (IRRF) of 15%, except for immune and exempt shareholders, as established in applicable law.

Dividends payable

Changes in the balance of dividends payable are set out as follows:

Unclaimed dividends

As of June 30, 2026, the balance of dividends not claimed by shareholders of Petrobras is US$ 170 recorded as other current liabilities, as described in note 17 (US$ 187 as of December 31, 2025). The payment of these dividends was not carried out due to the lack of registration data for which the shareholders are responsible with the custodian bank for the Company's shares.

Basic earnings per share are calculated by dividing the net income attributable to shareholders of Petrobras by the weighted average number of outstanding shares during the period.

Diluted earnings per share are calculated by adjusting the net income attributable to shareholders of Petrobras and the weighted average number of outstanding shares during the period taking into account the effects of all dilutive potential shares (equity instrument or contractual arrangements that are convertible into shares).

Basic and diluted earnings are identical as the Company has no potentially dilutive shares.
