16.1 Goodwill and intangible assets with indefinite useful lives

(1)Refers to the goodwill of the MMC Brasil business combination.

(2)Refers to other intangible assets with indefinite useful lives such as servitude of passage and electricity.

The goodwill is based on expected future profitability supported by valuation reports, after the purchase price allocation.

Goodwill is allocated to cash-generating units as presented in Note 28.4.

For the pulp cash-generating unit (“CGU”), the calculation of the value in use of non-financial assets is performed annually using the discounted cash flow method. In 2024 the Company used the strategic plan and the annual budget with projected increases to 2029 and the average rate in perpetuity of the cash generating units considering a nominal rate of 3.6% p.a. from this date, based on historical information for previous years, economic and financial projections from each specific market in which the Company has operations, and additionally include official information disclosed by independent institutions and government agencies.

The discount rate, after taxes, adopted by Management was 8.91% p.a., calculated based on the Weighted Average Cost of Capital (“WACC”).

The assumptions in the table set forth below were also adopted:

For the year ended December 31, 2024, the Company did not identify the need to record any impairment provision for intangible assets.

If the post-tax discount rate applied to the cash flow projections of both cash-generating units had been 1% higher than management’s estimates (9.91% instead of 8.91%), the Company would still not need to record an impairment provision.

The Company have considered and assessed possible changes for other key assumptions and have not identified any instances that could cause the carrying amount of the cash generating units to exceed its recoverable amount.

For the paper cash-generating unit (“CGU”), the asset recoverability test is carried out annually based on the EV/EBITDA multiple method. For the year ended December 31, 2024, the Company did not identify the need to record any impairment provision for intangible assets.
