(1) Represents weighted-average coupon rates for debt outstanding as of December 31, 2024. (2) This $900 million supplemental credit facility, entered in 2021, and amended in June 2024, offers a reduced interest rate margin with respect to borrowed amounts allocated to certain environmental sustainability or social investment initiatives. Proceeds of the supplemental credit facility also may be used for general corp orate purposes, but such proceeds are not eligible for a reduced interest rate margin. In May 2022, Dominion Energy borrowed $900 million. The proceeds from these borrowings were used to support environmental sustainability and social investment initiatives ($450 million) and for general corporate purposes ($450 million). In June 2022, Dominion Energy repaid $450 million borrowed for general corporate purposes. In March 2023, Dominion Energy borrowed $450 million with the proceeds used for general corporate purposes. In April 2023, Dominion Energy repaid $450 million borrowed for general corporate purposes. In September 2023, Dominion Energy borrowed $450 million under this facility with the proceeds used for general corporate purposes. In October 2023, Dominion Energy repaid $450 million borrowed for general corporate purposes. In May 2024, Dominion Energy repaid $450 million borrowed to support environmental sustainability and social investment initiatives. In June 2024, the facility was amended to extend the maturity date to June 2025. (3) Includes debt assumed by Dominion Energy from the merger of its former CNG subsidiary. (4) In October 2024, Dominion Energy redeemed all $685 million in outstanding principal amount of its October 2014 hybrids at par plus accrued interest including interest accrued at a floating rate effective October 2024. The notes would have otherwise matured in 2054. (5) These financings relate to certain pollution control equipment at Virginia Power’s generating facilities. In May 2024, Virginia Power remarketed three series of tax-exempt bonds, with an aggregate outstanding principal of $243 million to new investors. All three bonds will bear interest at a coupon of 3.80% until May 2027, after which they will bear interest at a market rate to be determined at that time. (6) Industrial revenue bonds totaling $68 million are secured by letters of credit that expire, subject to renewal, in the fourth quarter of 2025. (7) Represents debt associated with Eagle Solar. In February 2024, Eagle Solar redeemed the remaining principal outstanding of $279 million. The debt which otherwise would have matured in 2042 was nonrecourse to Dominion Energy and was secured by Eagle Solar's interest in certain solar facilities. As such, these borrowings are presented within securities due within one year in Dominion Energy’s Consolidated Balance Sheets at December 31, 2023. Dominion Energy recognized a charge of $10 million during the year ended December 31, 2024 within interest expense in its Consolidated Statements of Income in connection with the early redemption of these notes. (8) In October 2024, Dominion Energy redeemed all $27 million in outstanding principal amount of its 3.80% Peninsula Ports Authority of Virginia Coal Terminal Revenue Refunding Bonds at par plus accrued interest. The bonds would have otherwise matured in 2033. (9) Dominion Energy and Virginia Power’s weighted-average rate for securities due within one year was 3.70% and 3.73%, respectively, as of December 31, 2024.
