1.1.1 Principles of consolidation

In the preparation of the consolidated interim financial information the investments of one company in another, balances of asset and liability accounts, revenue transactions, costs and expenses were eliminated, as well as the effects of transactions conducted between the companies. Non-controlling interests in subsidiaries are presented within consolidated equity and net income.

Income and expenses of a subsidiary acquired are included in the consolidated statements of income and of comprehensive income from the date the Company gains control. Income and expenses of a subsidiary, in which the Company loses control, are included in the consolidated statements of income and of comprehensive income until the date the Company loses control.

When necessary, adjustments are made to the financial information of subsidiaries to bring their accounting policies into line with the Company’s accounting policies.

7. Recoverable taxes (Consolidated)

7.1. Recoverable taxes

Recoverable taxes are substantially represented by credits of Tax on Goods and Services (“ICMS”, the Brazilian VAT), Contribution for Social Security Financing (“COFINS”), Social Integration Program (“PIS”) and Income Tax (IR) and the Social Contribution on Net Income (CSLL).

	03/31/2026	12/31/2025
ICMS (7.1.1)	1,448,075	1,394,916
PIS and COFINS (7.1.2)	3,747,716	3,863,682
IRPJ and CSLL (7.1.3)	714,203	664,056
Others	145,173	144,643
Total	6,055,167	6,067,297
Current	2,182,455	2,003,389
Non-current	3,872,712	4,063,908

7.1.1 The recoverable ICMS net of provision for losses is substantially related to the following operations:

Tax credits are recognized mainly of the following nature: a) transactions of inputs and outputs of products subject to taxation of the own ICMS; b) interstate outflows of oil-related products, whose ICMS was prepaid by the supplier (Petrobras); c) credits for refunds of the ICMS-ST (tax substitution) overpaid when the estimated calculation base used is higher than that of the actual operation performed.

The amounts of recoverable ICMS are realized through the Company’s own operations subject to taxes, being a revolving credit, which means that the credits are monthly offset against the tax payable on sales and new credits are generated by the acquisition of inputs, as well as by the State's refund on tax substitution operations. Management estimates the realization of the credits classified in non-current assets within a term of up to 5 years.

7.1.2 The recoverable PIS and COFINS are substantially related to:

ICMS in the PIS and COFINS calculation basis - The balance of PIS and COFINS includes credits recorded under Laws 10,637/02 and 10,833/03, as well as amounts arising from a STF’s favorable decision (Theme 69) regarding the exclusion of ICMS from the PIS and COFINS calculation basis. The Company, through its subsidiaries, has credits in the amount of R$ 2,039,356 (R$ 2,039,260 as of December 31, 2025).

Supplementary Law 192 - On March 11, 2022 Supplementary Law (“LC” 192/22”) was published to reduce the tax burden of the fuel supply chain. Art. 9 of said law established the reduction of the PIS and COFINS tax rates levied on diesel, biodiesel and LPG to zero through December 31, 2022, ensuring at the same time the maintenance of credits taken across the whole supply chain up to September 21, 2022 (90 days after the publication of LC 194/22 that restricted the right to take credits on taxpayers), when it became effective.

The Company, through its subsidiaries, has credits in the amount of R$ 803,133 (R$ 814,319 as of December 31, 2025) from the LC 192/22. These credits were recorded considering the expectation of realization by the Company within a 5-year period from the date of generation, period in which the Company has the ability to use these credits. The estimated realization is updated annually considering the estimated future results.

7.1.3. Recoverable income and social contribution taxes - Relates to IRPJ and CSLL to be recovered by the Company and its subsidiaries, arising from the tax advances of previous years, as well as referring to lawsuits on the non-levy of IRPJ and CSLL on the monetary variation (SELIC) in the repetition of undue payments. Management estimates the realization of these credits within up to 5 years.
