(C) Belnick, LLC (d/b/a The Ubique Group) was transferred to a control investment effective March 31, 2025 (see endnote 48). Income recognized prior to the reclassification date is reflected as income from non-control/non-affiliate investments on our Consolidated Statement of Operations.
[5] Certain variable rate securities in our portfolio bear interest at a rate determined by a publicly disclosed base rate plus a basis point spread. The 1-Month Secured Overnight Financing Rate or “1M SOFR”, was 3.65% as of June 30, 2026. The 3-Month Secured Overnight Financing Rate or “3M SOFR”, was 3.73% as of June 30, 2026. The impact of a Secured Overnight Financing Rate (“SOFR”) credit spread adjustment, if applicable, is included within the stated all-in interest rate.
[6] Undrawn committed revolvers and delayed draw term loans to our portfolio companies incur commitment and unused fees ranging from 0.00% to 3.00%. As of June 30, 2026, $64,611 of undrawn revolver and delayed draw term loan commitments to our portfolio companies, of which $52,446 are considered at the Company’s sole discretion.
[7] Investment has been designated as an investment not “qualifying” under Section 55(a) of the Investment Company Act of 1940 (the “1940 Act”). Under the 1940 Act, we may not acquire any non-qualifying asset unless, at the time such acquisition is made, qualifying assets represent at least 70% of our total assets as calculated in accordance with regulatory requirements. As of June 30, 2026, our qualifying assets, as a percentage of total assets, stood at 81.94%. We monitor the status of these assets on an ongoing basis.
[8] The effective yield has been estimated to be 0% as expected future cash flows are anticipated to not be sufficient to repay the investment at cost. If the expected investment proceeds increase, there is a potential for future investment income from the
investment. Distributions, once received, will be recognized as return of capital, and when called, any remaining unamortized investment costs will be written off if the actual distributions are less than the amortized investment cost. To the extent that the cost basis of the SSN is fully recovered, any future distributions will be recorded as realized gains.
[9] This investment is in the equity class of the collateralized loan obligation (“CLO”) security, which is referred to as “Subordinated Structured Note,” or “SSN”. The SSN investments are entitled to recurring distributions which are generally equal to the excess cash flow generated from the underlying investments after payment of the contractual payments to debt holders and fund expenses. The current estimated yield, calculated using amortized cost, is based on the current projections of this excess cash flow taking into account assumptions which have been made regarding expected prepayments, losses and future reinvestment rates. These assumptions are periodically reviewed and adjusted. Ultimately, the actual yield may be higher or lower than the estimated yield if actual results differ from those used for the assumptions.
[10] Investment has been designated as an investment not “qualifying” under Section 55(a) of the Investment Company Act of 1940 (the “1940 Act”). Under the 1940 Act, we may not acquire any non-qualifying asset unless, at the time such acquisition is made, qualifying assets represent at least 70% of our total assets as calculated in accordance with regulatory requirements. As of June 30, 2025, our qualifying assets, as a percentage of total assets, stood at 85.27%. We monitor the status of these assets on an ongoing basis.
[11] The effective yield has been estimated to be 0% as expected future cash flows are anticipated to not be sufficient to repay the investment at cost. If the expected investment proceeds increase, there is a potential for future investment income from the investment. Distributions, once received, will be recognized as return of capital, and when called, any remaining unamortized investment costs will be written off if the actual distributions are less than the amortized investment cost. To the extent that the cost basis of the SSN is fully recovered, any future distributions will be recorded as realized gains.
[12] This investment is in the equity class of the collateralized loan obligation (“CLO”) security, which is referred to as “Subordinated Structured Note,” or “SSN”. The SSN investments are entitled to recurring distributions which are generally equal to the excess cash flow generated from the underlying investments after payment of the contractual payments to debt holders and fund expenses. The current estimated yield, calculated using amortized cost, is based on the current projections of this excess cash flow taking into account assumptions which have been made regarding expected prepayments, losses and future reinvestment rates. These assumptions are periodically reviewed and adjusted. Ultimately, the actual yield may be higher or lower than the estimated yield if actual results differ from those used for the assumptions.
[13] Security, or a portion thereof, is held by Prospect Capital Funding LLC (“PCF”), our wholly owned subsidiary and a bankruptcy remote special purpose entity, and is pledged as collateral for the Revolving Credit Facility and such security is not available as collateral to our general creditors (see Note 4). The fair value of the investments held by PCF as of June 30, 2026 was $2,155,016, representing 34.0% of our total investments.
[14] Certain variable rate securities in our portfolio bear interest at a rate determined by a publicly disclosed base rate plus a basis point spread. The 1-Month Secured Overnight Financing Rate or “1M SOFR”, was 4.32% as of June 30, 2025. The 3-Month Secured Overnight Financing Rate or “3M SOFR”, was 4.29% as of June 30, 2025. The PRIME Rate or “PRIME” was 7.50% as of June 30, 2025. The impact of a SOFR credit spread adjustment, if applicable, is included within the stated all-in interest rate.
[15] Security, or a portion thereof, is held by Prospect Capital Funding LLC (“PCF”), our wholly owned subsidiary and a bankruptcy remote special purpose entity, and is pledged as collateral for the Revolving Credit Facility and such security is not available as collateral to our general creditors (see Note 4). The fair value of the investments held by PCF at June 30, 2025 was $2,520,620, representing 37.8% of our total investments.
[16] The investment represents a unitranche loan with characteristics of a traditional first lien senior secured loan, but which pursuant to an agreement among lenders is divided among unaffiliated lenders into “first out” and “last out” tranches yielding different interest rates, where our investment is the “last out” tranche(s) of such unitranche loan, subject to payment priority in favor of a first out tranche held by an unaffiliated lender; or, the Company has entered into an intercreditor agreement that entitles the Company to the “last out” tranche of the first lien secured loans, whereby the “first out” tranche will receive priority as to the “last out” tranche(s) with respect to payments of principal, interest, and any other amounts due thereunder. Therefore, the Company may receive a higher interest rate than the “first out” lenders and the Consolidated Schedule of Investments above reflects such higher rate, as applicable.
[17] The interest rate on the below list of investments, which excludes those on non-accrual, contains a paid in kind (“PIK”) provision, whereby the issuer has either the option or the obligation to make interest payments with the issuance of additional securities. The interest rate in the schedule represents the current interest rate in effect for these investments.
The following table provides additional details on these PIK investments, including the maximum annual PIK interest rate allowed under the existing credit agreements, as of June 30, 2026:

[18] The investment represents a unitranche loan with characteristics of a traditional first lien senior secured loan, but which pursuant to an agreement among lenders is divided among unaffiliated lenders into “first out” and “last out” tranches yielding different interest rates, where our investment is the “last out” tranche(s) of such unitranche loan, subject to payment priority in favor of a first out tranche held by an unaffiliated lender; or, the Company has entered into an intercreditor agreement that entitles the Company to the “last out” tranche of the first lien secured loans, whereby the “first out” tranche will receive priority as to the “last out” tranche(s) with respect to payments of principal, interest, and any other amounts due thereunder. Therefore, the Company may receive a higher interest rate than the “first out” lenders and the Consolidated Schedule of Investments above reflects such higher rate, as applicable.
[19] The interest rate on the below list of investments, which excludes those on non-accrual, contains a paid in kind (“PIK”) provision, whereby the issuer has either the option or the obligation to make interest payments with the issuance of additional securities. The interest rate in the schedule represents the current interest rate in effect for these investments.
