Item 5.07.   Submission of Matters to a Vote of Security Holders.

(a)          Duke Energy Corporation (“Duke Energy”) held a special meeting of shareholders on August 23, 2011 to consider certain proposals relating to the proposed merger of Duke Energy and Progress Energy, Inc. (“Progress Energy”) under the terms of the Agreement and Plan of Merger, dated as of January 8, 2011, by and among Duke Energy, Diamond Acquisition Corporation, a wholly-owned subsidiary of Duke Energy, and Progress Energy (the “Merger”).

(b)         The shareholders approved three proposals relating to the Merger.  For more information on the proposals, see Duke Energy’s proxy statement/prospectus included in the registration statement filed with the U.S. Securities and Exchange Commission on July 7, 2011.  Set forth below are the final voting results for each of the proposals.

·                  Proposal to approve the amendment of the amended and restated certificate of incorporation of Duke Energy to provide for a 1-for-3 reverse stock split with respect to the issued and outstanding Duke Energy common stock in connection with the Merger

·                  Proposal to approve the issuance of Duke Energy common stock, par value $0.001 per share, to Progress Energy shareholders in connection with the Merger

·                  Proposal to adjourn the special meeting of the shareholders of Duke Energy, if necessary, to solicit additional proxies if there are not sufficient votes to approve either of the proposals above

Although Duke Energy and Progress Energy are targeting to complete the Merger by the end of 2011, if the Merger is not completed, Duke Energy will not amend its amended and restated certificate of incorporation to effect the reverse stock split, notwithstanding that Duke Energy’s shareholders have approved the amendment.

(d)                   Not applicable.

Item 8.01   Other Events.
