DNP Select Income Fund Inc. Discloses Sources of Distribution – Section 19(a) Notice

The Board of Directors of DNP Select Income Fund Inc. (NYSE:DNP), a closed-end fund advised by Duff & Phelps Investment Management Co. (the "Adviser"), previously announced the following monthly distribution on December 12, 2024:

The Fund adopted a managed distribution plan (the "Plan") in 2007. Under the Plan, the Fund will distribute all available investment income to its shareholders, consistent with the Fund's primary objective. If and when sufficient investment income is not available on a monthly basis, the Fund will distribute long-term capital gains or return of capital or both to its shareholders in order to maintain the 6.5 cent per share distribution level.

The following table sets forth the estimated amounts of the Fund's March 2025 distribution to shareholders of record at the close of business on March 31, 2025 (ex-date March 31, 2025), payable April 10, 2025, together with the cumulative distributions paid from the first day of the fiscal year to this month end from the following sources. All amounts are expressed per share of common stock based on U.S. generally accepted accounting principles which may differ from federal income tax regulations.

The Fund will issue a separate 19(a) notice at the time of each distribution using the most current financial information available. You should not draw any conclusions about the Fund's investment performance from the amount of these distributions or from the terms of the Plan.

The Fund estimates that it has distributed more than its income and capital gains; therefore, a portion of your distribution may be a return of capital. A return of capital may occur, for example, when some or all of the money that you invested in the Fund is paid back to you. A return of capital distribution does not necessarily reflect the Fund's investment performance and should not be confused with ‘yield' or ‘income'.

The amounts and sources of distributions reported in this notice are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon the Fund's investment experience during the remainder of the fiscal year and may be subject to changes based on tax regulations. The Fund or your broker will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.
