Item 1.01. Entry into a Material Definitive Agreement.

On November 5, 2026, in connection with the previously announced registered direct offering, Prospect Capital Corporation (the "Company") issued $300,000,000 in aggregate principal amount of its 8.95% Notes due 2031 (the "Notes") under an indenture, dated as of February 16, 2012 (the "Base Indenture"), between the Company and American Stock Transfer & Trust Company, LLC, as trustee (the "Original Trustee"), as amended by the Agreement of Resignation, Appointment and Acceptance, dated as of March 12, 2012, by and among the Company, the Original Trustee and U.S. Bank Trust Company, National Association, as trustee (the "Trustee"), as supplemented by the Supplemental Indenture, dated as of November 5, 2026 (the "Supplemental Indenture"), establishing the form and terms of the Notes (collectively, the "Indenture").

The Notes will mature on October 31, 2031 and will bear interest at a rate of 8.95% per year payable semi-annually in arrears on April 30 and October 31 of each year, commencing on April 30, 2027¹. The Notes will be general senior unsecured obligations of the Company, will rank equally in right of payment with the Company's existing and future senior unsecured debt², and will rank senior in right of payment to any potential subordinated debt, should any be issued in the future.

The Company may redeem some or all of the Notes, at its option, at any time and from time to time prior to April 30, 2029, at a price equal to 100% of the principal amount the Notes redeemed, plus an applicable "make-whole" premium as of, and accrued and unpaid interest on the Notes redeemed, if any, to, but not including, the applicable date of redemption. On and after April 30, 2029, the Company may redeem some or all of the Notes, at its option, at any time and from time to time, at the applicable redemption price set forth in the Supplemental Indenture³ plus accrued and unpaid interest on the Notes redeemed, if any, to, but excluding, the applicable date of redemption.

In addition, if a Change of Control Repurchase Event (as defined in the Supplemental Indenture) occurs prior to maturity of the Notes, holders of the Notes will have the right, at their option, to require the Company to repurchase for cash some or all of the Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest⁴ to, but not including, the repurchase date.

The Indenture contains certain covenants, including covenants requiring the Company to (i) comply with Section 18(a)(1)(A), as modified by Section 61(a), of the Investment Company Act of 1940, or any successor provisions, and (ii) provide financial information to the holders of the Notes and the Trustee if the Company is no longer subject to the reporting requirements under the Securities Exchange Act of 1934. These and other covenants are subject to important limitations and exceptions that are described in the Indenture.

The Notes were offered and sold in an offering that was made pursuant to the Company's effective shelf registration statement on Form N-2⁵ (Registration No. 333-293349) previously filed with the SEC, as supplemented by a prospectus supplement dated October 29, 2026, as further supplemented by Supplement No. 1 dated November 4, 2026 to the prospectus supplement dated October 29, 2026. The transaction closed on November 5, 2026.^{6 6}The Company expects net proceeds of the offering of approximately $283.4 million⁶ after deducting estimated offering expenses. The Company expects to use the net proceeds of the offering primarily for the refinancing of existing indebtedness, including but not limited to, the repayment of its 3.364% Notes due 2026 and/or borrowings under its revolving credit facility. The Company intends to use the remainder of the net proceeds from the offering, if any, to maintain balance sheet liquidity, including investments in high quality short-term debt instruments, and to make long-term investments in accordance with its investment objective.
