I tem 8.01. Other Events.

On April 4, 2024, Duke Energy Indiana, LLC (“DEI”) filed a general rate case with the Indiana Utility Regulatory Commission (the “IURC”). The filing requested an overall approximate 16.2% increase in retail revenues, or approximately $492 million, with an overall rate of return of approximately 6.5% based on approval of a 10.5% return on equity and a 53.0% equity component of the capital structure. The request was premised upon a DEI forecasted rate base of $12.5 billion as of December 31, 2025. On January 29, 2025, the IURC issued an order approving, among other things, a revenue increase of approximately $296 million for the total increase, predicated in part on a 9.75% return on equity and a 53.0% equity component of the capital structure. On February 3, 2025, the IURC issued an order clarifying the $296 million revenue requirement approved in its January 29, 2025, order.

Step 1 rates are estimated to become effective by March 2025, and Step 2 rates are estimated to be effective March 2026, trued up with carrying costs to January 2026. DEI will make a compliance filing with the IURC in February 2025 for their review and approval before Step 1 rates are implemented.

An overview providing additional detail on the filing is attached to this Form 8-K as Exhibit 99.1.
