IBERSOL | Integrated Management Report - 2024

INTEGRATED MANAGEMENT REPORT 2024 Methods and assumptions To determine the recoverable amount of financial investments and loans granted to subsidiaries, the fair value based on discounted cash flow projections and perpetuity was considered. The methods and main assumptions used to prepare the impairment tests were as follows: WACC 2024 Perpetuity Growth WACC 2023 Perpetuity Growth Financial Investments 7,44% 2,0% 7,23% 2,0% Impairment test results No impairment adjustments resulted from the impairment tests on subsidiaries, including amounts relating to capital contributions and loans. Sensitivity analyses In the current climate of uncertainty, the assumptions used are sensitive to changes in macroeconomic indicators and the business assumptions used by management. Considering the uncertainties regarding the recovery value of financial investments because they are based on the best information available at the time, changes in assumptions could have an impact on determining the level of impairment and, consequently, on results. From the sensitivity analysis carried out, a reduction in the growth rate in perpetuity of up to 1% and an increase in the WACC of up to 2% did not change the conclusion regarding the recoverability of the value of financial investments. 497
