This Series A Senior Secured Storm Recovery Bond is one of a duly authorized issue of Series A Senior Secured Storm Recovery Bonds of the Issuer (herein called the “Series A Bonds”), which Bonds are issuable in one Tranche. The Series A Bonds consist of one Tranche, which include this Senior Secured Storm Recovery Bond (herein called the “Storm Recovery Bonds”), all issued and to be issued under that certain Indenture dated as of November 25, 2025 (as supplemented by the Series Supplement (as defined below), the “Indenture”), among the Issuer, U.S. Bank Trust Company, National Association, in its capacity as indenture trustee (the “Indenture Trustee”, which term includes any successor indenture trustee under the Indenture) and U.S. Bank National Association, in its capacity as a securities intermediary (the “Securities Intermediary”, which term includes any successor securities intermediary under the Indenture) and as an account bank (the “Account Bank”), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights and obligations thereunder of the Issuer, the Indenture Trustee and the Holders of the Bonds. For purposes herein, “Series Supplement” means that certain Series Supplement dated as of November 25, 2025 between the Issuer and the Indenture Trustee. All terms used in this Storm Recovery Bond that are defined in the Indenture, as amended, restated, supplemented or otherwise modified from time to time, shall have the meanings assigned to such terms in the Indenture.

The principal of this Storm Recovery Bond shall be payable on each Payment Date only to the extent that amounts in the Collection Account for the Series A Bonds are available therefor, and only until the outstanding principal balance thereof on the preceding Payment Date (after giving effect to all payments of principal, if any, made on the preceding Payment Date) has been reduced to the principal balance specified in the Expected Sinking Fund Schedule that is attached to the Series Supplement as Schedule A, unless payable earlier because an Event of Default shall have occurred and be continuing and the Indenture Trustee or the Holders representing a majority of the Outstanding Amount of the Storm Recovery Bonds have declared the Series A Bonds to be immediately due and payable in accordance with Section 5.02 of the Indenture (unless such declaration shall have been rescinded and annulled in accordance with Section 5.02 of the Indenture). However, actual principal payments may be made in lesser than expected amounts and at later than expected times as determined pursuant to Section 8.02 of the Indenture. The entire unpaid principal amount of this Storm Recovery Bond shall be due and payable on the Final Maturity Date hereof.

All principal payments on the Storm Recovery Bonds shall be made pro rata to the Holders of the Storm Recovery Bonds entitled thereto based on the respective principal amounts of the Storm Recovery Bonds held by them.

Payments of interest on this Storm Recovery Bond due and payable on each Payment Date, together with the installment of principal or premium, if any, shall be made by check mailed first-class, postage prepaid, to the Person whose name appears as the Registered Holder of this Storm Recovery Bond (or one or more Predecessor Storm Recovery Bonds) on the Storm Recovery Bond Register as of the close of business on the Record Date or in such other manner as may be provided in the Indenture or the Series Supplement, except that (a) upon application to the Indenture Trustee by any Holder owning a Global Storm Recovery Bond evidencing this Storm Recovery Bond not later than the applicable Record Date, payment will be made by wire transfer to an account maintained by such Holder, and (b) if this Storm Recovery Bond is held in Book-Entry Form, payments will be made by wire transfer in immediately available funds to the account designated by the Holder of the applicable Global Storm Recovery Bond evidencing this Storm Recovery Bond unless and until such Global Storm Recovery Bond is exchanged for Definitive Storm Recovery Bonds (in which event payments shall be made as provided above) and except for the final installment of principal and premium, if any, payable with respect to this Storm Recovery Bond on a Payment Date, which shall be payable as provided below.

Under the laws of the State of South Carolina in effect on the date hereof, pursuant to S.C. Code Ann. § 58-27-1155, the State of South Carolina and its agencies (including the Commission) has pledged and agreed with the Holders, the Indenture Trustee, and other Financing Parties that the State of South Carolina and its agencies will not (a) alter the provisions of the Storm Recovery Law which make the Storm Recovery Charges imposed by the Financing Order irrevocable, binding, and nonbypassable charges; (b) take or permit any action that impairs or would impair the value of Storm Recovery Property or revises the Storm Recovery Costs for which recovery is authorized; (c) in any way impair the rights and remedies of the Holders, assignees and other Financing Parties; or (d) except for charges made pursuant to the formula-based adjustment mechanism authorized under the Storm Recovery Law, reduce, alter, or impair Storm Recovery Charges that are to be imposed, billed, charged, collected, and remitted for the benefit of the Holders, any assignee, the Indenture Trustee and any other Financing Parties until any and all principal, interest, premium, financing costs and other fees, expenses, or charges incurred, and any contracts to be performed, in connection with the related Series A Bonds have been paid and performed in full.

The Issuer and Duke Energy Carolinas hereby acknowledge that the purchase of this Series A Bond by the Holder hereof or the purchase of any beneficial interest herein by any Person are made in reliance on the foregoing pledge.

Neither the State of South Carolina, its agencies, and instrumentalities, nor its political subdivisions are liable on the Series A Bonds, and the Series A Bonds are not a debt or a general obligation of the State of South Carolina or any of its political subdivisions, agencies, or instrumentalities nor are they special obligations or indebtedness of the State, its agencies, or its political subdivisions. The Series A Bonds do not, directly, indirectly, or contingently obligate the State of South Carolina or its agencies, instrumentalities, or political subdivisions, to levy any tax or make any appropriation for payment of the Series A Bonds, other than in their capacities as consumers of electricity.

The Indenture also permits the Indenture Trustee to amend or waive certain terms and conditions set forth in the Indenture without the consent of Holders of the Storm Recovery Bonds issued thereunder, but with the satisfaction of the Commission Condition, if necessary.
