(1) Provisions for dismantling or restoration relate to the Bocamina and Tarapacá power plants. For the other provisions, the balance mainly reflects the payment associated with the extraordinary compensation mechanism for customers, which the Company’s subsidiaries Enel Distribución Chile and Enel Colina agreed with SERNAC, for an amount of ThUS$17,059.

(2) This mainly corresponds to a reduction in the SEF fine provision related to the rainfall events of August 2024.

(3) Corresponds to financial update; see Note 34.

(4) The increase observed in legal claims during 2024 is mainly explained by expenses recorded in the Distribution segment, which include, among others, fines issued by the SEF during the period. With respect to dismantling or restoration provisions, the decrease in 2024 is primarily explained by the increase in interest rates observed during the period. Finally, the increase in other provisions is mainly explained by the recognition of provisions related to the extraordinary compensation mechanism described above, in the amount of ThUS$17,120.
