(i) On December 11, 2024, the Luxembourg Parliament approved a reduction in the aggregate corporate income tax rate from 24.94% to 23.87%, effective January 1, 2025. As NEXA’s standalone net operating losses do not meet the recognition criteria, no deferred tax assets were recognized. Therefore, the tax rate reduction has no impact on the consolidated interim income statement.

(ii) Primarily related to income tax provision of Cerro Lindo Stability Agreement for the years 2014 to 2021. For further details, please refer to note 11 (d).

As of December 31, 2025, the Company has an accumulated amount of USD 1,166,839 not recognized as deferred taxes on net operating losses. From the total amount of unused tax losses, USD 106 have an expiration limit of 5 years, USD 884,617 of 17 years, USD 14,907 of 20 years, and USD 267,209 can be carried forward indefinitely.
