^{(2) Refers to the obligation adopted by RenovaBio to meet decarbonization targets for the gas and oil sector. The amounts are presented in Other operating income (expenses), net.}

^{(3) Refers substantially to PIS and COFINS credits recorded in 2021 and 2022. On March 15, 2017, due to general repercussions, the STF decided that ICMS does not compose the PIS and COFINS calculation basis. After filing of the Federal Government's Motion for Clarification, the STF definitively ruled about the thesis on May 13, 2021, reaffirming the exclusion of the ICMS from the PIS and COFINS calculation basis and modulating the effects of the decision for the lawsuits filed after March 15, 2017. Certain subsidiaries have credits arising from favorable decisions on the exclusion of ICMS from the PIS and COFINS calculation basis, and the respective subsidies for proving the amounts to be refunded were duly confirmed by Management and recorded in Other operating income (expenses), net in the statement of income.}
