(1) The main contingencies are disclosed in Note 36.3.

(2) See Note 3.a.

(3) The increase in 2024 primarily refers to the recognition of provisions in Enel Distribución Chile and Enel Colina related to agreements with SERNAC for the extraordinary compensation mechanism for customers affected by the prolonged supply outages that occurred during the extraordinary climatic events that occurred during the months of May and August 2024.

The expected timing and amount of any cash outflows related to the above provisions is uncertain and depends on the resolution of specific matters related to each one. For example, specifically for litigation, this depends on the final resolution of the corresponding legal claim. Management believes that provisions recognized in the financial statements cover the related risks appropriately.

(1) The increase in legal claims during the year 2024 is mainly explained by expenses recorded in the Distribution Segment, which include, among others, fines issued by the SEF (see Note 41.iii) during the period. Regarding decommissioning 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 primarily due to the recognition of provisions related to the extraordinary compensation mechanism for customers affected by the prolonged supply outages that occurred during the extraordinary and unforeseen events of August 1 and 2, 2024, which our subsidiaries Enel Distribución Chile and Enel Colina agreed upon with SERNAC (see Note 41.vi).

(2) Corresponds to the use of the provision in the dismantling processes of the Bocamina and Tarapacá power plants.

(3) Corresponding to financial update, see Note 34.

(4) The increase in the provision for dismantling or restoration during the year ended December 31, 2023 is primarily explained by an increase related to the Los Cóndores Power Plant of ThCh$19,053,494. The construction phase of the main elements of the civil works is practically finished, and the effect on the valuation of all obligations that originated from the drop in interest rates during the year. This was offset

by expenditure made during 2023, which reduce the balance of the provision and related to the dismantling processes of the Bocamina complex and the Tarapacá Power Plant.
