2. Financial covenants

Financial covenants are contractual commitments with respect to minimum or maximum financial ratios that the Company is obliged to meet at certain periods of time (quarterly, annually, etc.) and in some cases only when certain conditions are met. Most of the financial covenants of the Company limit leverage and track the ability to generate cash flow that will service the companies’ indebtedness. Certain companies are also required to periodically certify these covenants. The types of covenants and their respective limits vary according to the type of debt and contract.

The Equity corresponds to the Equity attributable to the owners of the parent company, which is contrasted with the level of Minimum Equity that will be readjusted by a percentage, provided it is positive of the annual variation of the Consumer Price Index multiplied by the difference between 1 minus the ratio of Non-Monetary Assets in Chile recorded in pesos and the Equity Attributable to the Parent Company.

Finally, in most contracts, the acceleration of the debt due to non-compliance with covenants does not occur automatically. Certain conditions must be met, such as the expiration of remediation periods, among others.

As of December 31, 2025, Enel Chile and its subsidiaries comply with all the financial obligations summarized herein. They also comply with other financial obligations whose non-compliance could result in the acceleration of the maturity of its financial commitments. Additionally, Management is not aware of any facts or circumstances indicating that the Company may have difficulties in meeting these covenants during or after the reporting period.
