FUND DISTRIBUTIONS AND MANAGED DISTRIBUTION PLAN

Fund Distributions and Managed Distribution Plan: DNP Select Income Fund Inc. (“DNP” or the “Fund”) has been paying a regular 6.5 cent per share monthly distribution on its common stock since July 1997. In February 2007, the Board of Directors adopted a Managed Distribution Plan, which provides for the Fund to continue to make a monthly distribution on its common stock of 6.5 cents per share. Under the Managed Distribution Plan, the Fund will distribute all available investment income to shareholders, consistent with the Fund’s primary investment objective. If and when sufficient investment income is not available on a monthly basis, the Fund will distribute long-term capital gains and/or return capital to its shareholders in order to maintain the steady distribution level that has been approved by the Board. If the Fund estimates that it has distributed more than its income and capital gains in a particular period, 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.”

You should not draw any conclusions about the Fund’s investment performance from the amount of the Fund’s distributions or from the terms of the Fund’s Managed Distribution Plan.

Whenever a monthly distribution includes a capital gain or return of capital component, the Fund provides you with a written statement indicating the sources of the distribution and the amount derived from each source.

The amounts and sources of distributions reported monthly in statements from the Fund are only estimates and are not provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon the Fund’s investment results during its fiscal year and may be subject to changes based on tax regulations. The Fund 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.

The Board reviews the operation of the Managed Distribution Plan on a quarterly basis, with the most recent review having been conducted in June 2023, and the Adviser uses data provided by an independent consultant to review for the Board the Managed Distribution Plan annually. The Board may amend, suspend or terminate the Managed Distribution Plan without prior notice to shareholders if it deems such action to be in the best interests of the Fund and its shareholders. For example, the Board might take such action if the Managed Distribution Plan had the effect of shrinking the Fund’s assets to a level that was determined to be detrimental to Fund shareholders. The suspension or termination of the Managed Distribution Plan could have the effect of creating a trading discount if the Fund’s stock is trading at or above net asset value, widening an existing trading discount, or decreasing an existing premium.

The Managed Distribution Plan is described in a Question and Answer format on your Fund’s website, www.dpimc.com/dnp, and discussed in the section of management’s letter captioned “About Your Fund.” The tax characterization of the Fund’s distributions for the last 5 years can also be found on the website under the “Tax Information” tab.

Dear Fellow Shareholders:

Performance Review: Consistent with its primary objective of current income and long-term growth of income, and its Managed Distribution Plan, the Fund declared six monthly distributions of 6.5 cents per share of common stock during the first half of 2023 fiscal year. The 6.5 cent per share monthly rate, without compounding, would be 78 cents annualized, which is equal to 7.2% of the April 30, 2023, closing price of $10.88 per share. Please refer to the inside front cover of this report and the portion of this letter captioned “About Your Fund” for important information about the Fund and its Managed Distribution Plan.

Your Fund had a market value total return (income plus change in market price) of 6.0% for the six months ended April 30, 2023, compared to the 5.8% total return of the Composite Index. The Composite Index is composed of the S&P 500® Utilities Index and the Bloomberg U.S. Utility Bond Index, weighted to reflect the stock and bond ratio of the Fund. On a net asset value (NAV) basis, the Fund’s total return (income plus change in the NAV of the portfolio) was 7.3% over the same period. On a longer-term basis, as of April 30, 2023, your Fund had a five-year annualized total return of 7.7% on a market value basis, compared to the 8.5% return of the Composite Index. On a NAV basis, the Fund’s total return was 8.2% for the same period.

1 | Past performance is not indicative of future results. Current performance may be lower or higher than performance in historical periods.

2 | Total return on market value assumes a purchase of common stock at the opening market price on the first business day and a sale at the closing market price on the last business day of the period shown in the table and assumes reinvestment of dividends at the actual reinvestment prices obtained under the terms of the Fund’s dividend reinvestment plan. In addition, when buying or selling stock, you would ordinarily pay brokerage expenses. Because brokerage expenses are not reflected in the above calculations, your total return net of brokerage expenses would be lower than the total return on market value shown in the table. Source: Administrator of the Fund.

3 | Total return on NAV uses the same methodology as is described in note 2, but with use of NAV for beginning, ending and reinvestment values. Because the Fund’s expenses (ratios detailed on page 14 of this report) reduce the Fund’s NAV, they are already reflected in the Fund’s total return on NAV shown in the table. NAV represents the underlying value of the Fund’s net assets, but the market price per share may be higher or lower than NAV. Source: Administrator of the Fund.

4 | The Composite Index is a composite of the returns of the S&P 500® Utilities Index and the Bloomberg U.S. Utility Bond Index (formerly known as the Barclays U.S. Utility Bond Index), weighted to reflect the stock and bond ratio of the Fund. The indices are calculated on a total return basis with dividends reinvested. Indices are unmanaged; their returns do not reflect any fees, expenses or sales charges; and they are not available for direct investment. Performance returns for the S&P 500® Utilities Index and Bloomberg U.S. Utility Bond Index were obtained from Bloomberg LP.

Portfolio Positioning in the Current Economic Environment: Macro economic factors remain in the driver’s seat for equity and bond markets. Bank failures, the direction of inflation and interest rates, and conflicting economic data continue to be the main topics of conversation among investors. Recently, the contentious negotiations around the debt limit were added to the list of concerns. While the banking crisis appeared to be contained after First Republic Bank was subsumed by JPMorgan Chase, regional banks continue to be under pressure. Inflation is proving sticky, which is pushing central banks to prolong the tightening cycle. As a result, a recession in the U.S. is a real possibility for the second half of the year or maybe 2024, which could spread to other regions around the world. Not surprisingly, we expect ongoing volatility in the global financial markets.

Positioning your Fund to weather these uncertainties is a key question for the portfolio management team. In general, we have taken a relatively defensive posture in both the equity and fixed income portions of the portfolio. Within the equity portion of the Fund, our holdings are focused on dividend-paying companies that have stable to growing earnings and cash flows that underpin the dividend. Other key characteristics we look for in our fundamental analysis of the companies are strong management teams, constructive regulatory environments, and solid balance sheets. For the fixed income portfolio within the Fund, the interest rate risk and yield curve distribution remain defensively positioned, with a duration less than half that of the broader utility-related fixed income market.

Going a little deeper into the various equity sectors of the portfolio, the utility sector generally is viewed as a defensive investment due to the regulated business model and attractive levels of dividend income. More recently, political and regulatory support for decarbonization has created long-term growth opportunities for the utility sector, providing strong earning visibility relative to the broader market. We have also diversified the utility holdings outside the U.S., investing in Canadian and European utilities that offer the same high-quality characteristics.

In addition to utilities, the Fund invests in sectors that have similar income and growth profiles, namely midstream energy and communications. The positioning of the midstream portfolio has become more defensive over the last couple years as the companies have focused on paying down debt, generating higher levels of cash flow and increasing returns to shareholders. Accordingly, we have more confidence in our midstream positioning than in past economic downturns given the high-quality focus and improved sector fundamentals.

The communications sector has been a more challenging sector in which to invest in recent years, compared to its historically defensive profile. The traditional telecommunications services providers have experienced an increasingly competitive marketplace for both wireless and broadband subscribers. However, the services they offer are essential and highly desired, lending a degree of defensiveness to their cash flows which, in turn, supports attractive dividend income to shareholders. Over the last few years, we have diversified our positioning within the communications sector to include wireless towers and data centers, which benefit from attractive, long-term demand growth and increasing dividends levels.

The coming months will undoubtedly present unforeseen challenges, but we expect to uncover opportunities as well. Based on our current views of macroeconomic trends, industry drivers, and geopolitical risks, we believe your Fund is appropriately positioned. Our objective is to invest in companies with experienced management teams and predictable business models that are positioned for success despite the uncertain economic environment. As always, we will continue to closely monitor global developments through our research and management meetings, incorporating changes to portfolio positioning as warranted.

Board of Directors Meetings: At the regular March and June 2023 Board of Directors’ meetings, the Board authorized the following monthly dividends:

|  | Cents Per Share |  |  |  | Record Date |  |  |  | Payable Date |  |  |  |  |  | Cents Per Share |  |  |  | Record Date |  |  |  | Payable Date |  |
|  | 6.5 |  |  |  | April 28 |  |  |  | May 10 |  |  |  |  |  | 6.5 |  |  |  | July 31 |  |  |  | August 10 |  |
|  | 6.5 |  |  |  | May 31 |  |  |  | June 12 |  |  |  |  |  | 6.5 |  |  |  | August 31 |  |  |  | September 11 |  |
|  | 6.5 |  |  |  | June 30 |  |  |  | July 10 |  |  |  |  |  | 6.5 |  |  |  | September 29 |  |  |  | October 10 |  |

About Your Fund: The Fund seeks to provide investors with a stable monthly dividend that is primarily derived from current fiscal year earnings and profits. In February 2007, the Board of Directors reaffirmed the 6.5 cent per share monthly distribution rate and formalized the monthly distribution process by adopting a Managed Distribution Plan (MDP). In 2008, the SEC granted the Fund exemptive relief that permits the Fund, subject to certain conditions, to make periodic distributions of long-term capital gains as frequently as twelve times a year in order to fulfill the terms of the MDP. The MDP is described on the inside front cover of this report and in a Question-and-Answer format on the Fund’s website, www.dpimc.com/dnp.

The Impact of Leverage on the Fund: The use of leverage enables the Fund to borrow at short-term rates and invest in higher yielding securities. As of April 30, 2023, the Fund had $1.105 billion of total leverage outstanding, which consisted of: (i) $75 million of floating rate preferred stock, (ii) $132 million of fixed rate preferred stock, (iii) $300 million of fixed rate secured notes and (iv) $598 million of floating rate secured debt outstanding under a committed loan facility. On that date, the total amount of leverage represented approximately 26% of the Fund’s total assets. On May 3, 2023, the Fund voluntarily redeemed $75 million of outstanding floating rate preferred stock. An increase in borrowings under the existing loan facility in the amount of $75 million was used to redeem these shares.

The amount and type of leverage used is reviewed by the Board of Directors based on the Fund’s expected earnings relative to the anticipated costs (including fees and expenses) associated with the leverage. In addition, the long-term expected benefits of leverage are weighed against the potential effect of increasing the volatility of both the Fund’s net asset value and the market value of its common stock. If the Fund were to conclude that the use of leverage was likely to cease being beneficial, it could modify the amount and type of leverage it uses or eliminate the use of leverage entirely.

The Impact of Interest Rates on the Fund: Along with the influence on the income provided from leverage, the level of interest rates can be a primary driver of bond returns, including the return on your Fund’s fixed income investments. For example, an extended environment of historically low interest rates adds an element of reinvestment risk, since the proceeds of maturing bonds may be reinvested in lower yielding securities. Alternatively, a sudden or unexpected rise in interest rates would likely reduce the total return of fixed income investments, since higher interest rates could be expected to depress the valuations of fixed rate bonds held in a portfolio.

Maturity and duration are measures of the sensitivity of a fund’s fixed income investments to changes in interest rates. More specifically, duration refers to the percentage change in a bond’s price for a given change in rates (typically +/- 100 basis points). In general, the greater the average maturity and duration of a portfolio, the greater is the potential percentage price volatility for a given change in interest rates. As of April 30, 2023, your Fund’s fixed income investments had an average maturity of 4.6 years and duration of 3.6 years, while the Bloomberg U.S. Utility Bond Index had an average maturity of 14.3 years and duration of 9.1 years.

3

In addition to your Fund’s fixed income investments, the income-oriented equity investments held in your Fund can be adversely affected by a rise in interest rates. However, if improved economic growth accompanies the rising rates, the impact on income-oriented equity investments may be mitigated.

As a practical matter, it is not possible for your Fund’s portfolio of investments to be completely insulated from unexpected moves in interest rates. Management believes that over the long term, the conservative distribution of fixed income investments along the yield curve and the growth potential of income-oriented equity holdings positions your Fund to take advantage of future opportunities while limiting volatility to some degree. However, a sustained and meaningful rise in interest rates from current levels would have the potential to significantly reduce the total return of leveraged funds holding income-oriented equities and fixed income investments, including DNP. A significant rise in interest rates would likely put downward pressure on both the net asset value and market price of such funds.

The percentage shown for each investment category is the total value of that category as a percentage of the net assets applicable to common stock of the Fund.

The Fund’s investments are carried at fair value which is defined as the price that the Fund might reasonably expect to receive upon selling an investment in a timely transaction to an independent buyer in the principal or most advantageous market of the investment. The three-tier hierarchy of inputs established to classify fair value measurements for disclosure purposes is summarized in the three broad levels listed below.

Level 1—quoted prices in active markets for identical securities

Level 2—other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.)

Level 3—significant unobservable inputs (including the Fund’s own assumptions in determining fair value of investments)

DNP SELECT INCOME FUND INC.

NOTES TO FINANCIAL STATEMENTS

April 30, 2023

(Unaudited)

Note 1. Organization:

DNP Select Income Fund Inc. (“DNP” or the “Fund”) was incorporated under the laws of the State of Maryland on November 26, 1986. The Fund commenced operations on January 21, 1987, as a closed-end diversified management investment company registered under the Investment Company Act of 1940 (the “1940 Act”). The primary investment objectives of the Fund are current income and long-term growth of income. Capital appreciation is a secondary objective.

Note 2. Significant Accounting Policies:

The Fund is an investment company that follows the accounting and reporting guidance of Accounting Standards Codification (“ASC”) Topic 946 applicable to Investment Companies.

The following are the significant accounting policies of the Fund:

A. Investment Valuation: Equity securities traded on a national or foreign securities exchange or traded over-the counter and quoted on the NASDAQ Stock Market are valued at the last reported sale price or, if there was no sale on the valuation date, then the security is valued at the mean of the bid and ask prices, in each case using valuation data provided by an independent pricing service, and are generally classified as Level 1. Equity securities traded on more than one securities exchange shall be valued at the last sale price on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities and are classified as Level 1. If there was no sale on the valuation date, then the security is valued at the mean of the closing bid and ask prices of the exchange representing the principal market for such securities. Debt securities are valued at the mean of the bid and ask prices provided by an independent pricing service when such prices are believed to reflect the fair value of such securities and are generally classified as Level 2. Any securities for which it is determined that market prices are unavailable or inappropriate are fair valued using the Adviser’s policies adopted by the Board of Directors and are classified as Level 2 or 3 based on the valuation inputs.

B. Investment Transactions and Investment Income: Security transactions are recorded on the trade date. Realized gains or losses from sales of securities are determined on the identified cost basis. Dividend income is recognized on the ex-dividend date. Interest income and expense are recognized on the accrual basis. Premiums on securities are amortized over the period remaining until first call date, if any, or if none, the remaining life of the security. Discounts are accreted over the remaining life of the security. Discounts and premiums are not amortized or accreted for tax purposes.

The Fund invests in master limited partnerships (“MLPs”) which make distributions that are primarily attributable to return of capital. Dividend income is recorded using management’s estimate of the percentage of income included in the distributions received from the MLP investments based on their historical dividend results. Distributions received in excess of this estimated amount are recorded as a reduction of cost of investments (i.e., a return of capital). The actual amounts of income and return of capital components of its distributions are only determined by each MLP after its fiscal year-end and may differ from the estimated amounts. For the six months ended April 30, 2023, 100% of the MLP distributions were treated as a return of capital.

(Unaudited)

C. Federal Income Taxes: It is the Fund’s intention to comply with requirements of Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”) applicable to regulated investment companies and to distribute substantially all of its taxable income and capital gains to its shareholders. Therefore, no provision for Federal income or excise taxes is required. Management of the Fund has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. The Fund’s federal income tax returns are generally subject to examination by the Internal Revenue Service for a period of three years after they are filed. State and local tax returns may be subject to examination for different periods, depending upon the tax rules of each applicable jurisdiction.

D. Foreign Currency Translation: Investment securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollar amounts at the date of valuation at the mean of the quoted bid and asked prices of such currencies. Purchases and sales of investment securities and income and expense items denominated in foreign currencies are translated into U.S. dollar amounts at the rate of exchange prevailing on the respective dates of such transactions. The Fund does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss on investments.

E. Accounting Standards: In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2020-04, (“ASU 2020-04”), Reference Rate Reform (Topic 848)—Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments in ASU 2020-04 provide optional temporary financial reporting relief from the effect of certain types of contract modifications due to the planned discontinuation of the London Interbank Offering Rate (“LIBOR”) and other interbank-offered based reference rates as of the end of 2021. In March 2021, the administrator for LIBOR announced the extension of the publication of a majority of the USD LIBOR settings to June 30, 2023. On December 21, 2022, the FASB issued ASU 2022-06 to defer the sunset date of ASC 848 until December 31, 2024. ASU 2020-04 is effective for certain reference rate-related contract modifications that occur during the period March 12, 2020 through December 31, 2024. Management has adopted ASU 2020-04 and ASU 2022-06.

F. Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Note 3. Agreements and Management Arrangements:

A. Adviser and Administrator: The Fund has an Advisory Agreement with Duff & Phelps Investment Management Co. (the “Adviser”) an indirect, wholly owned subsidiary of Virtus Investment Partners, Inc. (“Virtus”), to provide professional investment management services for the Fund and has an Administration Agreement with Robert W. Baird & Co. Incorporated (the “Administrator”) to provide administrative and management services for the Fund. The Adviser receives a quarterly fee at an annual rate of 0.60% of the Average Weekly Managed Assets of the Fund up to $1.5 billion and 0.50% of Average Weekly Managed Assets in excess thereof. The Administrator receives a quarterly fee at annual rates of 0.20% of Average Weekly Managed Assets up to $1 billion, and 0.10% of Average Weekly Managed Assets over $1 billion. For purposes

NOTES TO FINANCIAL STATEMENTS—(Continued)

(Unaudited)

of the foregoing calculations, “Average Weekly Managed Assets” is defined as the average weekly value of the total assets of the Fund minus the sum of all accrued liabilities of the Fund (other than the aggregate amount of any outstanding borrowings or other indebtedness constituting financial leverage).

B. Directors: The Fund pays each director not affiliated with the Adviser an annual fee. Total fees paid to directors for the six months ended April 30, 2023 were $225,473.

C. Affiliated Shareholder: At April 30, 2023, Virtus Partners, Inc. (a wholly owned subsidiary of Virtus) held 284,976 shares of the Fund, which represent 0.08% of the shares of common stock outstanding. These shares may be sold at any time.

Note 4. Investment Transactions:

Purchases and sales of investment securities (excluding short-term investments) for the six months ended April 30, 2023 were $120,234,649 and $194,778,854, respectively.

Note 5. Distributions and Tax Information:

At April 30, 2023, the approximate federal tax cost and aggregate gross unrealized appreciation (depreciation) were as follows:

Federal Tax Cost |  | Unrealized Appreciation |  | Unrealized Depreciation |  | Net Unrealized Appreciation
|  | $3,435,022,452 |  |  |  |  | $982,978,171 |  |  |  |  | $(180,797,845 | ) |  |  |  | $802,180,326 |

At October 31, 2022, the Fund had $51,305,226 of long-term capital loss carryovers available to offset future realized gains, if any, to the extent permitted by the Code. These capital losses are carried forward without expiration.

The Fund declares and pays monthly dividends on its common shares of a stated amount per share. Subject to approval and oversight by the Fund’s Board of Directors, the Fund seeks to maintain a stable distribution level (a Managed Distribution Plan) consistent with the Fund’s primary investment objective of current income. If and when sufficient investment income is not available on a monthly basis, the Fund will distribute long-term capital gains and/or return capital in order to maintain the $0.065 per common share distribution level. The character of distributions is determined in accordance with income tax regulations, which may differ from U.S. generally accepted accounting principles.

Note 6. Debt Financing:

The Fund has a Committed Facility Agreement (the “Facility”) with a commercial bank (the “Bank”) that allows the Fund to borrow cash up to a limit of $598,000,000. The Fund has also issued secured notes (the “Notes”). The Facility and Notes rank pari passu with each other and are senior, with priority in all respects to the outstanding common and preferred stock as to the payment of dividends and with respect to the distribution

17

DNP SELECT INCOME FUND INC.

NOTES TO FINANCIAL STATEMENTS—(Continued)

April 30, 2023

(Unaudited)

of assets upon dissolution, liquidation or winding up of the affairs of the Fund. Key information regarding the Facility and Notes is detailed below.

A. Borrowings Under the Facility: Borrowings under the Facility are collateralized by certain assets of the Fund (the “Hypothecated Securities”). The Fund expressly grants the Bank the right to re-register the Hypothecated Securities in its own name or in another name other than the Fund’s and to pledge, repledge, hypothecate, rehypothecate, sell, lend or otherwise transfer or use the Hypothecated Securities. Interest is charged at daily Secured Overnight Financing Rate (“SOFR”) plus an additional percentage rate of 0.95% on the amount borrowed. Prior to December 1, 2022, interest was changed at 1 month LIBOR plus an additional percentage rate of 0.85% on the amount borrowed. The Bank has the ability to require repayment of the Facility upon 179 days’ notice or following an event of default. For the six months ended April 30, 2023, the average daily borrowings under the Facility and the weighted daily average interest rate were $598,000,000 and 5.31%, respectively. As of April 30, 2023, the amount of such outstanding borrowings was $598,000,000 and the applicable interest rate was 5.76%.

The Bank has the ability to borrow the Hypothecated Securities (“Rehypothecated Securities”). The Fund is entitled to receive a fee from the Bank in connection with any borrowing of Rehypothecated Securities. The fee is computed daily based on a percentage of the difference between the fair market rate as determined by the Bank and the Fed Funds Open rate and is paid monthly. The Fund can designate any Hypothecated Security as ineligible for rehypothecation and can recall any Rehypothecated Security at any time and if the Bank fails to return it (or an equivalent security) in a timely fashion, the Bank will be liable to the Fund for the ultimate delivery of such security and certain costs associated with delayed delivery. In the event the Bank does not return the security or an equivalent security, the Fund will have the right to, among other things, apply and set off an amount equal to 100% of the then-current fair market value of such Rehypothecated Securities against any amounts owed to the Bank under the Facility. The Fund is entitled to receive an amount equal to any and all interest, dividends or distributions paid or distributed with respect to any Hypothecated Security on the payment date. At April 30, 2023, Hypothecated Securities under the Facility had a market value of $2,349,177,738 and Rehypothecated Securities had a market value of $563,270,915. If at the close of any business day, the value of all outstanding Rehypothecated Securities exceeds the value of the Fund’s borrowings, the Bank shall promptly, at its option, either reduce the amount of the outstanding Rehypothecated Securities or deliver an amount of cash at least equal to the excess amount.

B. Notes: In 2016, the Fund completed a private placement of $300,000,000 of Notes in two fixed-rate series. Net proceeds from the issuances were used to reduce the amount of the Fund’s borrowing under its Facility. The Notes are secured by a lien on all assets of the Fund of every kind, including all securities and all other investment property, equal and ratable with the liens securing the Facility. The Notes are not listed on any exchange or automated quotation system.

The Fund incurred costs in connection with the issuance of the Notes. These costs were recorded as a deferred charge and are being amortized over the respective life of each series of Notes. Amortization of these offering costs of $205,638 is included under the caption “Interest expense and amortization of deferred offering costs on secured notes” on the Statement of Operations and the unamortized balance is deducted from the carrying amount of the Notes under the caption “Secured notes” on the Statement of Assets and Liabilities.

Holders of the Notes are entitled to receive semi-annual interest payments until maturity. The Notes accrue interest at the annual fixed rate indicated above. The Notes are subject to optional and mandatory redemption in certain circumstances and subject to certain prepayment penalties and premiums.

The estimated fair value of the Notes was calculated, for disclosure purposes, based on estimated market yields and credit spreads for comparable instruments or representative indices with similar maturity, terms and structure. The Notes are categorized as Level 2 within the fair value hierarchy.

Note 7. Mandatory Redeemable Preferred Shares:

The Fund has issued and outstanding Mandatory Redeemable Preferred Shares (“MRP Shares”) with a liquidation preference of $100,000 per share.

Key terms of each series of MRP Shares at April 30, 2023 are as follows:

Series |  | Shares Outstanding |  | Liquidation Preference |  | Quarterly Rate Reset |  | Rate |  | Weighted Average Daily Rate |  | Mandatory Redemption Date |  | Estimated Fair Value

The Fund incurred costs in connection with the issuance of the MRP Shares. These costs were recorded as a deferred charge and are being amortized over the respective life of each series of MRP Shares. Amortization of these deferred offering costs of $104,609 is included under the caption “Interest expense and amortization of deferred offering costs on preferred shares” on the Statement of Operations and the unamortized balance is deducted from the carrying amount of the MRP Shares under the caption “Mandatory redeemable preferred shares” on the Statement of Assets and Liabilities.

Holders of the MRP Shares are entitled to receive quarterly cumulative cash dividend payments on the first business day following each quarterly dividend date which is the last day of each of March, June, September and December.

MRP Shares are subject to optional and mandatory redemption in certain circumstances. The redemption price per share is equal to the sum of the liquidation preference per share plus any accumulated but unpaid dividends plus, in some cases, an early redemption premium (which varies based on the date of redemption). The MRP Shares are not listed on any exchange or automated quotation system. The MRP Shares are categorized as Level 2 within the fair value hierarchy. The Fund is subject to certain restrictions relating to the MRP Shares such as maintaining certain asset coverage, effective leverage ratio and overcollateralization ratio requirements. Failure to comply with these restrictions could preclude the Fund from declaring any distributions to common shareholders and could trigger the mandatory redemption of the MRP Shares at liquidation value.

In general, the holders of the MRP Shares and of the Common Stock have equal voting rights of one vote per share. The holders of the MRP Shares are entitled to elect two members of the Board of Directors, and separate class votes are required on certain matters that affect the respective interests of the MRP Shares and the Common Stock.

Note 8. Offering of Shares of Common Stock:

The Fund filed a new shelf registration statement on March 3, 2023 allowing for an offering of up to $126,843,417 of common stock. This registration statement replaced a prior shelf registration statement filed on August 5, 2021 that allowed for an offering size of up to $200,000,000. The $126,843,417 of common stock covered by the new registration statement reflects the amount of common stock that had not yet been issued under the prior registration statement at the time the new registration statement was filed. The shares of common stock may be offered and sold directly to purchasers, through at-the-market offerings using an equity distribution agent, or through a combination of these methods. The Fund entered into an agreement with Wells Fargo Securities, LLC to act as the Fund’s equity distribution agent. The Fund incurred costs in connection with this offering of common stock. These costs are recorded as a deferred charge and are being amortized as shares of common stock are sold. Amortization of these offering costs of $13,930 for the six months ended April 30, 2023 is recorded as a reduction in paid in surplus on common stock. The weighted average premium to NAV per share sold during the six months ended April 30, 2023 was 22.81%.

Note 9. Indemnifications:

Under the Fund’s organizational documents, its Officers and Directors are indemnified against certain liabilities arising out of the performance of their duties to the Fund. In addition, in the normal course of business, the Fund enters into contracts that provide general indemnifications to other parties. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not occurred. However, the Fund has not had prior claims or losses pursuant to these arrangements and expects the risk of loss to be remote.

RENEWAL OF INVESTMENT ADVISORY AGREEMENT (Unaudited)

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the terms of the Fund’s investment advisory agreement must be reviewed and approved at least annually by the Board of Directors of the Fund (the “Board”), including a majority of the directors who are not “interested persons” of the Fund, as defined in section 2(a)(19) of the 1940 Act (the “Independent Directors”). Section 15(c) of the 1940 Act also requires the Fund’s directors to request and evaluate, and the Fund’s investment adviser to furnish, such information as may reasonably be necessary to evaluate the terms of the investment advisory agreement. To assist the Board with this responsibility, the Board has appointed a Contracts Committee, which is composed of the Independent Directors of the Fund and acts under a written charter that was most recently amended on December 17, 2015. A copy of the charter is available on the Fund’s website at www.dpimc.com/dnp and in print to any shareholder, upon request.

The Contracts Committee, assisted by the advice of independent legal counsel, conducted an annual review of the terms of the Fund’s contractual arrangements, including the investment advisory agreement with Duff & Phelps Investment Management Co. (the “Adviser”). Set forth below is a description of the Contracts Committee’s annual review of the Fund’s investment advisory agreement, which provided the material basis for the Board’s decision to continue the investment advisory agreement.

In the course of the Contracts Committee’s review, the members of the Contracts Committee considered all of the information they deemed appropriate, including informational materials furnished by the Adviser in response to a request made by independent counsel on behalf of the Contracts Committee. In arriving at its recommendation that continuation of the investment advisory agreement was in the best interests of the Fund and its shareholders, the Contracts Committee took into account all factors that it deemed relevant, without identifying any single factor or group of factors as all-important or controlling. Among the factors considered by the Contracts Committee, and the conclusion reached with respect to each, were the following:

Nature, extent, and quality of services. The Contracts Committee considered the nature, extent and quality of the services provided to the Fund by the Adviser. Among other materials, the Adviser furnished the Contracts Committee with a copy of its most recent investment adviser registration form (Form ADV). In evaluating the quality of the Adviser’s services, the Contracts Committee noted the various complexities involved in the operations of the Fund, such as the use of multiple forms of leverage (senior notes, preferred stock and borrowings under a credit facility), the rehypothecation of portfolio securities pledged under the credit facility and the Fund’s ongoing “at-the-market” offering program for its common stock, and concluded that the Adviser is consistently providing high-quality services to the Fund in an increasingly complex environment. The Contracts Committee also considered the length of service of the individual professional employees of the Adviser who provide services to the Fund. In the Contracts Committee’s view, the long-term service of capable and conscientious professionals provides a significant benefit to the Fund and its shareholders. The Contracts Committee also considered the Fund’s investment performance as discussed below. The Contracts Committee also took into account its evaluation of the quality of the Adviser’s code of ethics and compliance program. The Contracts Committee also considered the consistent quality of the services being provided by the Adviser even in light of the disruptions related to the COVID-19 pandemic. In light of the foregoing, the Contracts Committee concluded that it was generally satisfied with the nature, extent and quality of the services provided to the Fund by the Adviser.

Investment performance of the Fund and the Adviser. The Contracts Committee reviewed the Fund’s investment performance over time and compared that performance to other funds in its peer group. In making its

21

comparisons, the Contracts Committee utilized data provided by the Adviser and a report from Broadridge (“Broadridge”), an independent provider of investment company data. As reported by Broadridge, the Fund’s net asset value (“NAV”) total return ranked above the median among all leveraged closed-end equity funds categorized by Broadridge as utility funds for the 1-, 3-, 5- and 10-year periods ended June 30, 2022. The Adviser provided the Contracts Committee with performance information for the Fund for the 1-, 3-, and 5-year periods ended June 30, 2022, measured against two benchmarks: the Lipper Utility Peer Group Average and a composite of the S&P 500 Utilities Index and the Bloomberg U.S. Utility Bond Index (the “S&P Composite”), calculated to reflect the relative weights of the Fund’s equity and bond portfolios. The Contracts Committee noted that on an NAV total return basis, the Fund outperformed the Lipper Utility Peer Group Average (the “Peer Group Average”) for the 1-, 3- and 5-year periods ended June 30, 2022. On a market value basis, the Fund’s total return outperformed the Peer Group Average for the 1-and 5-year periods ended June 30, 2022, while trailing the Peer Group Average for the 3-year period ended June 30, 2022. The Contracts Committee also noted that the Fund’s NAV total return underperformed the S&P Composite for the 1-, 3- and 5-year periods ended June 30, 2022. On a market value basis, the Fund underperformed the S&P Composite for the 3- and 5-year periods ended June 30, 2022 while outperforming the S&P Composite for the 1-year period ended June 30, 2022.

The Contracts Committee also considered that since current income is one of the Fund’s primary objectives, one measure of the Adviser’s performance is the fact that the Fund has been paying a regular 6.5 cent per share monthly distribution on its common stock since July 1997, and that the Fund’s annualized distribution rate of 7.18% based on market value as of June 30, 2022 compares favorably with the 3.00% yield of the S&P Utilities Index (and the 1.70% yield of the S&P 500 Index, representing the broader market), while considering that the Fund’s distribution rate contains a component of return of capital. The Contracts Committee noted that the Fund’s managed distribution plan provides for the Fund to distribute all available investment income to shareholders and, if sufficient investment income is not available on a monthly basis, to distribute long-term capital gains and/or return capital to its shareholders in order to maintain the 6.5 cent per share monthly distribution level. Additionally, the Contracts Committee considered the fact that since 1990, the Fund’s common stock has traded at a premium to NAV over 96% of the time (even though most closed-end funds trade at a discount to NAV) as further evidence of the Adviser’s successful management of the Fund’s investment portfolio.

Costs of services and profits realized. The Contracts Committee considered the reasonableness of the compensation paid to the Adviser, in both absolute and comparative terms, and also the profits realized by the Adviser and its affiliates from its relationship with the Fund. To facilitate this analysis, the Contracts Committee retained Broadridge to furnish a report comparing the Fund’s management fee (defined as the sum of the advisory fee and administration fee) and other expenses to the similar expenses of other comparable funds selected by Broadridge (the “Broadridge expense group”). The Contracts Committee reviewed, among other things, information provided by Broadridge comparing the Fund’s contractual management fee rate (at common asset levels) and actual management fee rate (reflecting fee waivers, if any) as a percentage of total assets and as a percentage of assets attributable to common stock to other funds in its Broadridge expense group. Based on the data provided on management fee rates, the Contracts Committee noted that: (i) the Fund’s contractual management fee rate at a common asset level was lower than the median of its Broadridge expense group; (ii) the actual total expense rate was above the median on a total asset basis and on the basis of assets attributable to common stock; and (iii) the actual management fee rate was lower than the median of its Broadridge expense group on a total asset basis and on the basis of assets attributable to common stock.

In reviewing expense ratio comparisons between the Fund and other funds in the peer group selected by Broadridge, the Contracts Committee considered leverage-related expenses separately from other expenses. The Contracts Committee noted that leverage-related expenses are not conducive to direct comparisons between funds, because the leverage-related expenses on a fund’s income statement are significantly affected by the amount, type and tenor of the leverage used by each fund, among other factors, and considered the Adviser’s

22

report indicating that the tenor and diversification of the Fund’s leverage were the primary drivers of the difference between the Fund’s investment-related expenses and those of other funds in the Broadridge peer group. Also, unlike all the other expenses of the Fund (and other funds) which are incurred in return for a service, leverage expenses are incurred in return for the receipt of additional capital that is then invested by the Fund (and other funds using leverage) in additional portfolio securities that produce revenue directly offsetting the leverage expenses. Accordingly, in evaluating the cost of the Fund’s leverage, the Contracts Committee considered the specific benefits to the Fund’s common shareholders of maintaining such leverage, noting that the Fund’s management and the Board regularly monitor the amount, form, terms and risks of the Fund’s leverage, and that such leverage has continued to be accretive, generating net income for the Fund’s common shareholders over and above its cost.

The Adviser also furnished the Contracts Committee with copies of its financial statements, and the financial statements of its parent company, Virtus Investment Partners, Inc. The Adviser also provided information regarding the revenue and expenses related to its management of the Fund, and the methodology used by the Adviser in allocating such revenue and expenses among its various clients. In reviewing those financial statements and other materials, the Contracts Committee examined the profitability of the investment advisory agreement to the Adviser and determined that the profitability of that contract was reasonable in light of the services rendered to the Fund. The Contracts Committee considered that the Adviser must be able to compensate its employees at competitive levels in order to attract and retain high-quality personnel to provide high-quality service to the Fund. The Contracts Committee concluded that the investment advisory fee was the product of arm’s length bargaining and that it was fair and reasonable to the Fund.

Economies of scale. The Contracts Committee considered whether the Fund has appropriately benefited from any economies of scale. The Contracts Committee noted the breakpoints whereby the advisory fee is reduced at higher asset levels and concluded that any economies of scale are being shared between Fund shareholders and the Adviser in an appropriate manner.

Comparison with other advisory contracts. The Contracts Committee also received comparative information from the Adviser with respect to its standard fee schedule for investment advisory clients other than the Fund. The Contracts Committee noted that, among all accounts managed by the Adviser, the Fund’s advisory fee rate is comparable to the Adviser’s standard fee schedule at certain asset levels. However, the Contracts Committee noted that the services provided by the Adviser to the Fund are significantly more extensive and demanding than the services provided by the Adviser to its non-investment company, institutional accounts. Specifically, in providing services to the Fund, the Contracts Committee considered that the Adviser needs to: (1) comply with the 1940 Act, the Sarbanes-Oxley Act and other federal securities laws and New York Stock Exchange requirements, (2) provide for external reporting (including semi-annual reports to shareholders, annual audited financial statements and disclosure of proxy voting), tax compliance and reporting (which are particularly complex for investment companies), requirements of Section 19 of the 1940 Act relating to the source of distributions, (3) prepare for and attend meetings of the Board and its committees, (4) communicate with Board and committee members between meetings, (5) communicate with a retail shareholder base consisting of thousands of investors, (6) manage the use of different forms of financial leverage and respond to changes in the financial markets and regulatory environment that could affect the amount and type of the Fund’s leverage and (7) respond to unanticipated issues in the financial markets or regulatory environment that can impact the Fund. Based on the fact that the Adviser only provides the foregoing services to its investment company clients and not to its institutional account clients, the Contracts Committee concluded that the management fees charged to the Fund are reasonable compared to those charged to other clients of the Adviser, when the nature and scope of the services provided to the Funds are taken into account. Furthermore, the

23

Contracts Committee noted that many of the Adviser’s other clients would not be considered “like accounts” of the Fund because these accounts are not of similar size and do not have the same investment objectives as, or possess other characteristics similar to, the Fund.

Indirect benefits. The Contracts Committee considered possible sources of indirect benefits to the Adviser from its relationship to the Fund, including brokerage and soft dollar arrangements, and enhanced reputation that may aid in obtaining new clients. In this regard, the Contracts Committee noted that the Fund does not utilize affiliates of the Adviser for brokerage purposes, that the Adviser does not use third-party soft dollar arrangements and that the Adviser has continued to seek opportunities to reduce brokerage costs borne by the Fund.

Conclusion. Based upon its evaluation of all material factors, including the foregoing, and assisted by the advice of independent legal counsel, the Contracts Committee concluded that the continued retention of the Adviser as investment adviser to the Fund was in the best interests of the Fund and its shareholders. Accordingly, the Contracts Committee recommended to the full Board that the investment advisory agreement with the Adviser be continued for a one-year term ending March 1, 2024. On December 14, 2022, the Contracts Committee presented its recommendations, and the criteria on which they were based, to the full Board, whereupon the Board, including all of the Independent Directors voting separately, accepted the Contracts Committee’s recommendations and unanimously approved the continuation of the current investment advisory agreement with the Adviser for a one-year term ending March 1, 2024.
