the deduction of amounts paid in the basis of calculation of income taxes in Brazil, as well as to the incidence of Corporate Income Tax
(CIT) on transactions abroad, linked to judicial and administrative proceedings.

Additionally, the company has uncertain tax treatments
not provisioned in the statement of financial position, both in Brazil and abroad, related to income taxes, amounting to R$ 24,366 (R$
33,408 as of December 31, 2024), related to judicial and administrative proceedings, especially regarding the treatment of income from
subsidiaries domiciled abroad and the incidence of corporate income tax (IRPJ) and social contribution tax (CSLL) on transfer pricing.

The company also holds other positions that may
be considered uncertain tax treatments of income taxes, amounting to R$ 31,378 (R$ 26,468 as of December 31, 2024), given the possibility
of divergent interpretation by the tax authority. These uncertain tax treatments are supported by technical assessments and a tax risk
assessment methodology; therefore, the company believes that such positions will be accepted by the tax authorities, understood as the
government bodies that decide whether tax treatments are acceptable under tax law, including judicial courts.

Thus, as of September 30, 2025, uncertain tax positions,
both in Brazil and abroad, amount to R$ 59,039 (R$ 64,624 as of December 31, 2024), for which Petrobras will continue to defend its position.
