Item 7.01. Regulation FD Disclosure.

On July 3, 2024, the Public Service Commission of South Carolina (the “PSCSC”) issued a written order (the “Order”) approving an increase in base rates, and approving nearly all components of a settlement agreement reached by Duke Energy Carolinas, LLC (“DEC”), the South Carolina Office of Regulatory Staff (the “ORS”) and other parties on May 17, 2024, which resolved all issues in DEC’s base rate case proceeding originally filed with the PSCSC on January 4, 2024.

The Order revised recovery of certain environmental compliance costs, the only provision of the settlement agreement not fully approved by the PSCSC. Revised customer rates will be effective August 1, 2024 and are based upon a South Carolina retail rate base of $7.4 billion and a return on equity of 9.94% and a capital structure of 51.21% equity and 48.79% debt. The Order will result in Duke Energy Corporation recognizing a one-time net pre-tax accounting charge of approximately $30 to 40 million, to be recognized in the second quarter of 2024.

An overview providing additional detail on the Order is attached to this Form 8-K as Exhibit 99.1. The information in Exhibit 99.1 is being furnished pursuant to this Item 7.01 and shall not be deemed “filed” for purposes of Section 18 of the Securities and Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section.
