(iii) On April 27, 2023, the Company was merged into Ultracargo Logística S.A.

As of December 31, 2023, the Company assessed the balances of goodwill shown in the table above for impairment. The determination of value in use involves assumptions, judgments, and estimates of cash flows, such as growth rates of revenues, costs and expenses, estimates of investments and working capital, and discount rates. The assumptions about growth projections of future cash flows are based on the Company’s business plan of its operating segments, as well as comparable market data, and represent management’s best estimate of the economic conditions that will exist over the economic life of the various CGUs to which goodwill is related. The main key assumptions used by the Company to calculate the value in use are described below.

Period of evaluation: the evaluation of the value in use is calculated for a period of five years, after which the Company calculates the perpetuity, considering the possibility of carrying the business on indefinitely.

Nominal discount rate and real growth rate: the nominal discount and real growth rates used to extrapolate the projections at December 31, 2023 ranged from 10.1% to 11.1% and 0% to 0.5% p.a., respectively, depending on of the CGU analyzed.

Revenue from sales and services, costs and expenses, and gross margin: considers the budget prepared for 2024 and the long-term strategic plan prepared by Management and approved by the Board of Directors.

b. Acquisition and provision for decarbonization credits

The Company, through its subsidiary IPP, has annual decarbonization obligation adopted by Brazilian National Biofuels Policy (“RenovaBio”), implemented by Law No. 13,576/2017, with additional regulations established by Decree No. 9,888/2019 and Ordinance No. 419 on November 20, 2019, issued by the Brazilian Ministry of Mines and Energy.

The decarbonization credits (“CBIOS”) acquired are recorded at historical cost in intangible assets, being retired according to decree in the year to fulfill the individual target set by the National Agency of Petroleum, Natural Gas and Biofuels (“ANP”).

The obligation is registered under “Provision for decarbonization credits” in proportion to the annual targets established by the ANP, through the average acquisition cost of credits acquired and the fair value of traded credits on B3 on the closing date to the credits to be acquired. In 2023, the amount of R$ 741,982 was registered (R$ 272,969 in 2022). Acquired decarbonization credits that have not been retired and the result of the provision for the acquisition of new credits recognized in the period are presented under Intangibles assets and Other operating income, respectively.

On April 25, 2023, Decree No. 11,499/2023 was published, which exceptionally establishes the deadline for retirement of decarbonization credits until September 2023 to meet the 2022 target and until March 2024 to meet the 2023 target. The company has complied with the deadline for retiring decarbonization credits from the 2022 target.

c. Software
