 below are the names and certain biographical information about the
nominees for the position of director and the continuing directors of the Funds. Except as noted in the footnotes to the table below:

| • |     | all of the directors are elected to the DNP Board by the holders of DNP common stock voting as a separate class; |

| • |     | all of the directors are elected to the DPG Board by the holders of DPG common stock and preferred stock, voting 
 as a single class; and                                                                                           |

| • |     | all of the directors are elected to the DTF Board by the holders of DTF common stock. |

All of the directors of the Funds, except Mr. Aylward, are classified as independent directors because none of them are “interested
persons” of the Funds, as defined in the Investment Company Act of 1940 (the “1940 Act”). Mr. Aylward is an “interested person” of the Funds by reason of his position as President and Chief Executive Officer of Virtus
Investment Partners, Inc. (“Virtus”), the ultimate parent company of the Funds’ investment adviser, Duff & Phelps Investment Management Co. (the “Adviser”). Each of the current directors, except Mareilé B.
Cusack and Mr. Aylward, formerly served on the Board of Directors of Duff & Phelps Utility and Corporate Bond Trust Inc. (“DUC”) until its merger into DNP in March 2021. The term “Fund Complex” refers to the Funds
and all other investment companies advised by affiliates of Virtus, the Adviser’s ultimate parent company. The address for all directors (including the nominees) is c/o Duff & Phelps Investment Management Co., 10 South Wacker
Drive, Suite 1900, Chicago, Illinois 60606.
