Duff & Phelps Utility and Infrastructure Fund Inc. (NYSE: DPG), a closed-end investment management company advised by Duff & Phelps Investment Management Co. (“Duff & Phelps”), today exercised an option to voluntarily redeem (“Redemption Date”) its remaining 1,400,000 issued and outstanding Floating Rate Mandatory Redeemable Preferred Shares, Series C (the “Series C MRP Shares”) (CUSIP No. 26433C4#9).

The Series C MRP Shares were redeemed at the liquidation preference of $25.00 per share and accumulated but unpaid dividends and distributions up to, but excluding, the Redemption Date.

The redemption of the Series C MRP Shares is being funded by DPG’s issuance of 1,000,000 Floating Rate Mandatory Redeemable Preferred Shares, Series D (the “Series D MRP Shares”) and borrowing $10 million under the Fund’s existing credit facility with a major commercial bank. The issuance of Series D MRP Shares and additional borrowing under the credit facility occurred on May 29, 2025.

The 1,000,000 Series D MRP Shares were issued at a liquidation value of $25.00 per share, par value of $0.001 per share, with a maturity date of May 29, 2030. The Series D MRP Shares have a floating rate based on the three-month secured overnight financing rate (SOFR) plus 2.00% and will pay dividends on a quarterly basis.

Duff & Phelps believes this capital restructuring is prudent management of DPG’s borrowings to facilitate its use of leverage.
