PROSPECT CAPITAL CORP

Note 1. Organization

In this report, the terms “Prospect”, “the Company”, “we”, “us” and “our” mean Prospect Capital Corporation and its subsidiaries unless the context specifically requires otherwise.

Prospect is a financial services company that primarily lends to and invests in middle market privately-held companies. We are a closed-end investment company incorporated in Maryland. We have elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940 (the “1940 Act”). As a BDC, we have elected to be treated as a regulated investment company (“RIC”), under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). We were organized on April 13, 2004, and were funded in an initial public offering completed on July 27, 2004.

On May 15, 2007, we formed a wholly owned subsidiary Prospect Capital Funding LLC (“PCF”), a Delaware limited liability company and a bankruptcy remote special purpose entity, which holds certain of our portfolio loan investments that are used as collateral for the revolving credit facility at PCF. On September 30, 2014, we formed a wholly-owned subsidiary Prospect Yield Corporation, LLC (“PYC”) and effective October 23, 2014, PYC holds a portion of our collateralized loan obligations (“CLOs”), which we also refer to as subordinated structured notes (“SSNs”). Each of these subsidiaries have been consolidated since operations commenced.

We consolidate certain of our wholly owned and substantially wholly owned holding companies formed by us in order to facilitate our investment strategy. The following companies are included in our consolidated financial statements and are collectively referred to as the “Consolidated Holding Companies”: Belnick Holdings of Delaware, LLC (“Belnick Delaware”); CP Holdings of Delaware LLC (“CP Holdings”); Credit Central Holdings of Delaware, LLC; Energy Solutions Holdings Inc.; First Tower Holdings of Delaware LLC (“First Tower Delaware”); MITY Holdings of Delaware Inc.; Nationwide Acceptance Holdings LLC; NMMB Holdings, Inc. (“NMMB Holdings”); NPH Property Holdings, LLC (“NPH”); Prospect Opportunity Holdings I, Inc. (“POHI”); SB Forging Company, Inc. (“SB Forging”); STI Holding, Inc.; UTP Holdings Group Inc. (“UTP Holdings”); Valley Electric Holdings I, Inc. (“Valley Holdings I”); and Valley Electric Holdings II, Inc. (“Valley Holdings II”).

We are externally managed by our investment adviser, Prospect Capital Management L.P. (“Prospect Capital Management” or the “Investment Adviser”). Prospect Administration LLC (“Prospect Administration” or the “Administrator”), a wholly-owned subsidiary of the Investment Adviser, provides administrative services and facilities necessary for us to operate.

Our investment objective is to generate both current income and long-term capital appreciation. We intend to invest primarily in privately owned United States (“U.S.”) middle market companies, in senior and secured first lien loans and, to a lesser extent, second lien loans, as well as equity and equity-linked investments with capital-appreciation potential (such as senior and secured convertible debt, preferred equity, common equity and warrants). Most of our investments will be in private U.S. companies; however, we may also invest to some extent in broadly-traded public companies and non-U.S. companies (subject to compliance with BDC requirements to invest at least 70% of assets in “eligible portfolio companies,” which are generally privately offered securities issued by U.S. private or thinly-traded companies). We are a non-diversified company within the meaning of the 1940 Act.

Note 2. Significant Accounting Policies

Basis of Presentation and Consolidation

The accompanying consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) pursuant to the requirements for reporting on Form 10-K, ASC 946, Financial Services—Investment Companies (“ASC 946”), and Articles 3, 6, and 12 of Regulation S-X.

Under the 1940 Act, ASC 946, and the regulations pursuant to Article 6 of Regulation S-X, we are precluded from consolidating any entity other than another investment company or an operating company which provides substantially all of its services to benefit us. Our consolidated financial statements include the accounts of Prospect, PCF, PYC, and the Consolidated Holding Companies. The consolidated financial statements reflect all adjustments and reclassifications that, in the opinion of management, are necessary for the fair presentation of the results of operations and financial condition as of and for the periods presented. All intercompany balances and transactions have been eliminated in consolidation. The financial results of our non-substantially wholly-owned holding companies and operating portfolio company investments are not consolidated in the financial statements. Any operating companies owned by the Consolidated Holding Companies are not consolidated.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents consist of cash and highly liquid investments with an original maturity of three months or less at the date of purchase. Cash, cash equivalents, and restricted cash are carried at cost, which approximates fair value.

All cash and restricted cash balances are maintained with high credit quality financial institutions. Cash and restricted cash held at financial institutions, at times, has exceeded the Federal Deposit Insurance Corporation (“FDIC”) insured limit. The Company has not incurred any losses on these accounts, and the credit risk exposure is mitigated by the financial strength of the banking institutions where the amounts are held.

Restricted cash relates to a contractual requirement for our Revolving Credit Facility to maintain a minimum cash balance in a reserve account. The contractual requirement is based upon our outstanding borrowing on our Revolving Credit Facility.

Reclassifications

Certain reclassifications have been made in the presentation of prior consolidated financial statements and accompanying notes to conform to the presentation as of and for the year ended June 30, 2025. See Note 12. Income Taxesand Note 16. Financial Highlights.

In our Form 10-K for the year ended June 30, 2024 filed on August 28, 2024, we previously reported total interest income of$770,312 and$760,785 for theyears ended June 30, 2024 and June 30, 2023, from our control and non-control/non-affiliate investments, respectively, within our Consolidated Statement of Operations. In accordance with Regulation S-X 6-07.01 Statement of Operations – Investment Incomeand to conform to the presentation for theyear ended June 30, 2025, we have subsequently reclassified portions of the prior year interest income to separately state the amounts attributable to payment-in-kind interest income.

Use of Estimates

The preparation of the consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of income, expenses, and gains and losses during the reported period. Changes in the economic environment, financial markets, creditworthiness of the issuers of our investment portfolio and any other parameters used in determining these estimates could cause actual results to differ, and these differences could be material.

Investment Classification

We are a non-diversified company within the meaning of the 1940 Act. As required by the 1940 Act, we classify our investments by level of control. As defined in the 1940 Act, “Control Investments” are those where there is the ability or power to exercise a controlling influence over the management or policies of a company. Control is generally deemed to exist when a company or individual possesses a beneficial ownership of more than 25% of the voting securities of an investee company. Under the 1940 Act, “Affiliate Investments” are defined by a lesser degree of influence and are deemed to exist through owning, controlling, or holding with power to vote, 5% or more of the outstanding voting securities of another person. “Non-Control/Non-Affiliate Investments” are those that are neither Control Investments nor Affiliate Investments.

As a BDC, we must not acquire any assets other than “qualifying assets” specified in the 1940 Act unless, at the time the acquisition is made, at least 70% of our total assets are qualifying assets (with certain limited exceptions). As of June 30, 2025 and June 30, 2024, our qualifying assets as a percentage of total assets, stood at 85.27% and 83.78%, respectively.

Investment Transactions

Investments are recognized when we assume an obligation to acquire a financial instrument and assume the risks for gains or losses related to that instrument. Specifically, we record all security transactions on a trade date basis. We determine the fair value of our investments on a quarterly basis (as discussed in Investment Valuation below), with changes in fair value reflected as a net change in unrealized gains (losses) from investments in the Consolidated Statement of Operations.

Investments are derecognized when we assume an obligation to sell a financial instrument and forego the risks for gains or losses related to that instrument. Realized gains or losses on the sale of investments are calculated using the specific identification method. Amounts for inve stments traded but not yet settled are reported in Due to Broker or Due from Broker, in the Consolidated Statements of Assets and Liabilities. As of June 30, 2025 and June 30, 2024, we haveno assets going through foreclosure.

Foreign Currency

Foreign currency amounts are translated into US Dollars (USD) on the following basis:

i. fair value of investment securities, other assets and liabilities—at the spot exchange rate on the last business day of the period; and

ii. purchases and sales of investment securities, income and expenses—at the rates of exchange prevailing on the respective dates of such investment transactions, income or expenses.

We do 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 fair values of investments held or disposed of during the period. Such fluctuations are included within the net realized and net change in unrealized gains or losses from investments in the Consolidated Statements of Operations.

Investment Risks

Our investments are subject to a variety of risks. Those risks include the following:

Market Risk

Market risk represents the potential loss that can be caused by a change in the fair value of the financial instrument.

Credit Risk

Credit risk represents the risk that we would incur if the counterparties failed to perform pursuant to the terms of their agreements with us.

Liquidity Risk

Liquidity risk represents the possibility that we may not be able to rapidly adjust the size of our investment positions in times of high volatility and financial stress at a reasonable price.

Interest Rate Risk

Interest rate risk represents a change in interest rates, which could result in an adverse change in the fair value of an interest-bearing financial instrument.

Prepayment Risk

Many of our debt investments allow for prepayment of principal without penalty. Downward changes in interest rates may cause prepayments to occur at a faster than expected rate, thereby effectively shortening the maturity of the security and making us less likely to fully earn all of the expected income of that security and reinvesting in a lower yielding instrument.

Structured Credit Related Risk

CLO investments may be riskier and less transparent to us than direct investments in underlying companies. CLOs typically will have no significant assets other than their underlying senior secured loans. Therefore, payments on CLO investments are and will be payable solely from the cash flows from such senior secured loans.

Foreign Currency

Investments denominated in foreign currencies and foreign currency transactions may involve certain considerations and risks not typically associated with those of domestic origin. These risks include, but are not limited to, currency fluctuations and revaluations and future adverse political, social and economic developments, which could cause investments in foreign markets to be less liquid and prices more volatile than those of comparable U.S. companies or U.S. government securities.

Other Risks

Political developments, including civil conflicts and war, sanctions or other measures by the United States or other governments, natural disasters, public health crises and other events outside the Company’s control can directly or indirectly have a material adverse impact on the Company and our portfolio companies.

As a BDC, and in accordance with the 1940 Act, we fair value our investment portfolio on a quarterly basis, with any unrealized gains and losses reflected in net increase (decrease) in net assets resulting from operations on our Consolidated Statement of Operations. To value our investments, we follow the guidance of ASC 820, Fair Value Measurement(“ASC 820”), that defines fair value, establishes a framework for measuring fair value in conformity with GAAP, and requires disclosures about fair value measurements. In accordance with ASC 820, the fair value of our investments is defined as the price that we would receive upon selling an investment in an orderly transaction to an independent buyer in the principal or most advantageous market in which that investment is transacted.

ASC 820 classifies the inputs used to measure these fair values into the following hierarchy:

Level 1: Quoted prices in active markets for identical assets or liabilities, accessible by us at the measurement date.

Level 2: Quoted prices for similar assets or liabilities in active markets, or quoted prices for identical or similar assets or liabilities in markets that are not active, or other observable inputs other than quoted prices.

Level 3: Unobservable inputs for the asset or liability.

In all cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to each investment.

Our Board of Directors has established procedures for the valuation of our investment portfolio. These procedures are detailed below.

Investments for which market quotations are readily available are valued at such market quotations, subject to the quotations meeting sufficient volume and liquidity metrics.

For most of our investments, market quotations are not available. With respect to investments for which market quotations are not readily available or when such market quotations are deemed not to represent fair value, due to factors such as volume and frequency of price quotes, our Board of Directors has approved a multi-step valuation process each quarter, as described below.

1. Each portfolio company or investment is reviewed by our investment professionals with independent valuation firms engaged by our Board of Directors.

2. The independent valuation firms prepare independent valuations for each investment based on their own independent assessments and issue their report.

3. The Audit Committee of our Board of Directors reviews and discusses with the independent valuation firms the valuation reports, and then makes a recommendation to the Board of Directors of the value for each investment.

4. The Board of Directors discusses valuations and determines the fair value of each investment in our portfolio in good faith based on the input of the Investment Adviser, the respective independent valuation firm and the Audit Committee.

Our non-CLO investments that are classified as Level 3 are valued utilizing a yield technique, enterprise value (“EV”) technique, asset recovery technique, discounted cash flow technique, or a combination of techniques, as appropriate. The yield technique uses loan spreads for loans and other relevant information implied by market data involving identical or comparable assets or liabilities. Under the EV technique, the EV of a portfolio company is first determined and allocated over the portfolio company’s securities in order of their preference relative to one another (i.e., “waterfall” allocation). To determine the EV, we typically use a market (multiples) valuation approach that considers relevant and applicable market trading data of guideline public companies, transaction metrics from precedent merger and acquisitions transactions, and/or a discounted cash flow technique. The asset recovery technique is intended to approximate the net recovery value of an investment based on, among other things, assumptions regarding liquidation proceeds based on a hypothetical liquidation of a portfolio company’s assets. The discounted cash flow technique converts future cash flows or earnings to a range of fair values from which a single estimate may be derived utilizing an appropriate discount rate. The fair value measurement is based on the net present value indicated by current market expectations about those future amounts.

In applying these methodologies, additional factors that we consider in valuing our investments may include, as we deem relevant: security covenants, call protection provisions, and information rights; the nature and realizable value of any collateral; the portfolio company’s ability to make payments; the principal markets in which the portfolio company does business; publicly available financial ratios of peer companies; the principal market; and enterprise values, among other factors.

Our investments in CLOs are classified as Level 3 fair value measured securities under ASC 820 and are valued using a discounted multi-path cash flow model. The CLO structures are analyzed to identify the risk exposures and to determine an appropriate call date (i.e., expected maturity). These risk factors are sensitized in the multi-path cash flow model using Monte Carlo simulations, which is a simulation used to model the probability of different outcomes, to generate probability-weighted (i.e., multi-path) cash flows from the underlying assets and liabilities. These cash flows are discounted using appropriate market discount rates, and relevant data in the CLO market as well as certain benchmark credit indices are considered, to determine the value of each CLO investment. In addition, we generate a single-path cash flow utilizing our best estimate of expected cash receipts, and assess the reasonableness of the implied discount rate that would be effective for the value derived from the multi-path cash flows. We are not responsible for and have no influence over the asset management of the portfolios underlying the CLO investments we hold, as those portfolios are managed by non-affiliated third-party CLO collateral managers. The main risk factors are default risk, prepayment risk, interest rate risk, downgrade risk, and credit spread risk.

Convertible Notes

We have recorded the Convertible Notes at their contractual amounts and at issuance, we determined that the embedded conversion options in the Convertible Unsecured Notes are not required to be separately accounted for as a derivative under ASC 815, Derivatives and Hedging. See Note 5 for further discussion on our Convertible Notes outstanding.

Revenue Recognition

Interest income, adjusted for amortization of premium and accretion of discount, is recorded on an accrual basis. Original issue discounts and market discounts are capitalized and accreted into interest income over the respective terms of the applicable loans using the effective interest method or straight-line, as applicable, and adjusted only for material amendments or prepayments. Upon a prepayment of a loan, prepayment premiums, original issue discount, or market discounts are recorded as interest income.

Loans are placed on non-accrual status when there is reasonable doubt that principal or interest will be collected. Unpaid accrued interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans are either applied to the cost basis or interest income, depending upon management’s judgment of the collectability of the loan receivable. Non-accrual loans are restored to accrual status when past due principal and interest is paid and in management’s judgment, is likely to remain current and future principal and interest collections when due are probable. Interest received and applied against cost while a loan is on non-accrual, and payment-in-kind (“PIK”) interest capitalized but not recognized while on non-accrual, is recognized prospectively on the effective yield basis through maturity of the loan when placed back on accrual status, to the extent deemed collectible by management. As of June 30, 2025 and June 30, 2024, approximately 0.3% and 0.3%, respectively, of our total assets at fair value are in non-accrual status.

Some of our loans and other investments may have contractual PIK interest or dividends. PIK income computed at the contractual rate is accrued into income and reflected as receivable up to the capitalization date. PIK investments offer issuers the option at each payment date of making payments in cash or in additional securities. When additional securities are received, they typically have the same terms, including maturity dates and interest rates as the original securities issued. On these payment dates, we capitalize the accrued interest (reflecting such amounts in the basis as additional securities received). PIK generally becomes due at maturity of the investment or upon the investment being called by the issuer. At the point that we believe PIK is not fully expected to be realized, the PIK investment will be placed on non-accrual status. When a PIK investment is placed on non-accrual status, the accrued, uncapitalized interest or dividends are reversed from the related receivable through interest or dividend income, respectively. We do not reverse previously capitalized PIK interest or dividends. Upon capitalization, PIK is subject to the fair value estimates associated with their related investments. PIK investments on non-accrual status are restored to accrual status if we believe that PIK is expected to be realized.

Interest income from investments in Subordinated Structured Notes (typically preferred shares, income notes or subordinated notes of CLO funds) and “equity” class of security of securitized trust is recorded based upon an estimation of an effective yield to expected maturity utilizing assumed cash flows in accordance with ASC 325-40, Beneficial Interests in Securitized Financial Assets. We monitor the expected cash inflows from our CLO and securitized trust equity investments, including the expected residual payments, and the effective yield is determined and updated periodically. The Company modified its policy during the year ended June 30, 2024, with respect to the timing of when it recognizes realized losses for certain CLO equity investments for which the Company determines that a CLO’s expected remaining cash flows do not exceed amortized cost basis. In such situations, the amortized cost basis of the CLO is written down and recognized as a realized loss.

Dividend income is recorded on the ex-dividend date. Each distribution received from limited liability company (“LLC”) and limited partnership (“LP”) investments is evaluated to determine if the distribution should be recorded as dividend income or a return of capital. Generally, the Company will not record distributions from equity investments in LLCs and LPs as dividend income unless there are sufficient current or accumulated tax-basis earnings and profits in the LLC or LP prior to the distribution. Distributions that are classified as a return of capital are recorded as a reduction in the cost basis of the investment.

Other income consists of structuring fees, amendment fees, overriding royalty interests, receipts related to net profit and revenue interests, deal deposits, administrative agent fees, and other miscellaneous receipts, which are recognized as revenue when received.

Structuring fees and certain other amendment or advisory fees are considered fees in exchange for the provision of certain services and are subject to the provisions of ASC Topic 606, Revenue from Contracts with Customers(“ASC 606”). All other types of income are derived from lending or equity investments, which is recognized in accordance with ASC 310-20, Nonrefundable Fees and Other Costs. See Note 10. Other Income.

Realized gains or losses on the sale of investments are calculated using the specific identification method. Refer to Investment Transactions above.

Federal and State Income Taxes

We have elected to be treated as a RIC and intend to continue to comply with the requirements of the Code applicable to RICs. We are required to distribute at least 90% of our investment company taxable income and intend to distribute (or retain through a deemed distribution) all of our investment company taxable income and net capital gain to stockholders; therefore, we have made no provision for income taxes. The character of income and gains that we will distribute is determined in accordance with income tax regulations that may differ from GAAP. Book and tax basis differences relating to stockholder dividends and distributions and other permanent book and tax differences are reclassified to paid-in capital.

If we do not distribute (or are not deemed to have distributed) at least 98% of our annual ordinary income and 98.2% of our capital gains in the calendar year earned, we will generally be required to pay an excise tax equal to 4% of the amount by which 98% of our annual ordinary income and 98.2% of our capital gains exceed the distributions from such taxable income for the year. To the extent that we determine that our estimated current year annual taxable income will be in excess of estimated current year dividend distributions from such taxable income, we accrue excise taxes, if any, on estimated excess taxable income. As of June 30, 2025, we donot expect to have any excise tax due for the 2025 calendar year. Thus, we have not accrued any excise tax for this period.

If we fail to satisfy the annual distribution requirement or otherwise fail to qualify as a RIC in any taxable year, we would be subject to tax on all of our taxable income at regular corporate income tax rates. We would not be able to deduct distributions to stockholders, nor would we be required to make distributions. Distributions would generally be taxable to our individual and other non-corporate taxable stockholders as ordinary dividend income eligible for the reduced maximum rate applicable to qualified dividend income to the extent of our current and accumulated earnings and profits, provided certain holding period and other requirements are met. Subject to certain limitations under the Code, corporate distributions would be eligible for the dividends-received deduction. To qualify again to be taxed as a RIC in a subsequent year, we would be required to distribute to our stockholders our accumulated earnings and profits attributable to non-RIC years. In addition, if we failed to qualify as a RIC for a period greater than two taxable years, then, in order to qualify as a RIC in a subsequent year, we would be required to elect to recognize and pay tax on any net built-in gain (the excess of aggregate gain, including items of income, over aggregate loss that would have been realized if we had been liquidated) or, alternatively, be subject to taxation on such built-in gain recognized for a period of five years.

We follow ASC 740, Income Taxes (“ASC 740”). ASC 740 provides guidance for how uncertain tax positions should be recognized, measured, presented, and disclosed in the consolidated financial statements. ASC 740 requires the evaluation of tax positions taken or expected to be taken in the course of preparing our tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold are recorded as a tax benefit or expense in the current year. As of June 30, 2025, we did not record any unrecognized tax benefits or liabilities. Management’s determinations regarding ASC 740 may be subject to review and adjustment at a later date based upon factors including, but not limited to, an on-going analysis of tax laws, regulations, and interpretations thereof. Although we file both federal and state income tax returns, our major tax jurisdiction is federal. Our federal tax returns for the tax years ended August 31, 2022 and thereafter remain subject to examination by the Internal Revenue Service.

Taxable Subsidiaries

Certain of our consolidated subsidiaries are subject to U.S. federal and state corporate-level income taxes. As of June 30, 2025, and June 30, 2024, no net tax benefit or expense was recorded since they did not result in a material provision for income taxes. As of June 30, 2025, and June 30, 2024, the net deferred tax asset or liability was not material to the financial statements after taking into account valuation allowances.

Dividends and Distributions to Common Shareholders

Dividends and distributions to common stockholders are recorded on the ex-dividend date. The amount, if any, to be paid as a monthly dividend or distribution is approved by our Board of Directors quarterly and is generally based upon our management’s estimate of our future taxable earnings. Net realized capital gains, if any, are distributed at least annually.

Our distributions may exceed our earnings, and therefore, portions of the distributions that we make may be a return of the money originally invested and represent a return of capital distribution to shareholders for tax purposes.

Financing Costs

We record origination expenses related to our Revolving Credit Facility as deferred financing costs. These expenses are deferred and amortized as part of interest expense using the straight-line method over the stated life of the obligation for our Revolving Credit Facility. Debt issuance costs and origination discounts related to our Convertible Notes and Public Notes are presented net against the outstanding principal of the respective instrument and amortized as part of interest expense using the effective interest method over the stated life of the respective instrument. Debt issuance costs and origination discounts related to our Prospect Capital InterNotes® (collectively, with our Convertible Notes and Public Notes, our “Unsecured Notes”) are net against the outstanding principal amount of our Prospect Capital InterNotes® and are amortized as part of interest expense using the straight-line method over the stated maturity of the respective note. In the event that we modify or extinguish our debt before maturity, we follow the guidance in ASC 470-50, Modification and Extinguishments (“ASC 470-50”). For modifications to or exchanges of our Revolving Credit Facility, any unamortized deferred costs relating to lenders who are not part of the new lending group are expensed. For extinguishments of our Unsecured Notes, any unamortized deferred costs are deducted from the carrying amount of the debt in determining the gain or loss from the extinguishment.

Unamortized deferred financing costs are presented as a direct deduction to the respective Unsecured Notes (see Notes 5, 6, and 7).

We may record registration expenses related to shelf filings as prepaid expenses. These expenses consist principally of the Securities and Exchange Commission (“SEC”) registration fees, legal fees and accounting fees incurred. These prepaid expenses are charged to capital upon the receipt of proceeds from an equity offering or charged to expense if no offering is completed. As of June 30, 2025 and June 30, 2024, there areno prepaid expenses related to registration expenses and all amounts incurred have been expensed.

Per Share Information

In accordance with ASC 946, senior equity securities, such as preferred stock, are not considered in the calculation of net asset value per common share. Net asset value per common share also excludes the effects of assumed conversion of outstanding convertible securities, regardless of whether their conversion would have a diluting effect. Therefore, our net asset value is presented on the basis of per common share outstanding as of the applicable period end.

We compute earnings per common share in accordance with ASC 260, Earnings Per Share (“ASC 260”). Basic earnings per common share is calculated by dividing the net increase (decrease) in net assets resulting from operations applicable to common stockholders by the weighted average number of shares of common stock outstanding. Diluted earnings per share gives effect to all dilutive potential common shares outstanding using the if-converted method for our Convertible Preferred Stock and, prior to our full redemption of the 2025 Notes on March 3, 2025, our Convertible Notes (together, “convertible instruments”). Diluted earnings per share excludes all dilutive potential common shares if their effect is anti-dilutive.

In accordance with ASC 480-10-S99-3A, the Company’s Preferred Stock (as defined in “Note 9. Equity Offerings, Offering Expenses, and Distributions”) has been classified in temporary equity on the Consolidated Statement of Assets and Liabilities. Beginning with the period ended September 30, 2021, limitations on our ability to exercise our Issuer Optional Conversion on the 5.50% Preferred Stock and 6.50% Preferred Stock (each, as defined below) created the possibility of redemption outside of the Company’s control if dividends on the Preferred Stock have accumulated and been unpaid for a period oftwo years. The 5.50% Preferred Stock,6.50% Preferred Stock and 5.35% Series A Preferred Stock issued as temporary equity is recorded net of offering costs and issuance costs due to this possibility. The 5.50% Preferred Stock issued prior to the issuance of our 5.35% Series A Preferred Stock has a carrying value on our Consolidated Statement of Assets and Liabilities equal to liquidation value per share.

The Floating Rate Preferred Stock and 7.50% Preferred Stock (each, as defined below) are redeemable at the election of the holder at any time and is probable of redemption outside of the Company’s control. In accordance with ASC 480-10-S99-3A, the Floating Rate Preferred Stock and 7.50% Preferred Stock are accreted to redemption value within temporary equity upon issuance. Accretion to redemption value is treated as an adjustment to net increase (decrease) in net assets resulting from operations applicable to common stockholders on our Consolidated Statement of Operations.

Accrued and unpaid dividends relating to the Preferred Stock are included in the preferred stock carrying value on the Consolidated Statement of Assets and Liabilities. Dividends declared on the Preferred Stock are included in preferred stock dividends on the Consolidated Statement of Operations.

Segment Reporting

In accordance with ASC Topic 280 - Segment Reporting (“ASC 280”), the Company has determined that it has a single operating and reporting segment. As a result, the Company’s segment accounting policies are the same as described herein and the Company does not have any intra-segment sales and transfers of assets.

Recent Accounting Pronouncements

The Company considers the applicability and impact of all accounting standard updates (“ASU”) issued by the Financial Accounting Standards Board (the “FASB”). ASUs not listed were assessed by the Company and either determined to be not applicable or expected to have minimal impact on its consolidated financial statements.

In November 2023, the FASB issued ASU 2023-07,“Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”)”, which enhances disclosure requirements about significant segment expenses that are regularly provided to the chief operating decision maker (the “CODM”). ASU 2023-07, among other things, (i) requires a single segment public entity to provide all of the disclosures as required by ASC 280, (ii) requires a public entity to disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources and (iii) provides the ability for a public entity to elect more than one performance measure. ASU 2023-07 is effective for the fiscal years beginning after December 15, 2023, and interim periods beginning with the first quarter ended September 30, 2025. Early adoption is permitted and retrospective adoption is required for all prior periods presented. The Company has adopted ASU 2023-07 effective June 30, 2025 and concluded that the application of this guidance did not have a material impact on its consolidated financial statements. See Note 17 for more information on the effects of the adoption of ASU 2023-07.

In December 2023, the FASB issued ASU No. 2023-09,“Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”),” which intends to improve the transparency of income tax disclosures. ASU No. 2023-09 is effective for fiscal years beginning after December 15, 2024 and is to be adopted on a prospective basis with the option to apply retrospectively. The Company is currently assessing the impact of this guidance, however, the Company does not expect a material impact to its consolidated financial statements.

Note 3. Portfolio Investments

The ranges of unobservable inputs used in the fair value measurement of our Level 3 investments as of June 30, 2025 were as follows:

(1)Represents the fair value of investments held by NPRC (see National Property REIT Corp section below) through its wholly owned subsidiary, National General Lending Limited (“NGL”), and valued using a discounted cash flow valuation technique.

(2)Represents the implied discount rate based on our internally generated single-cash flow model that is derived from the fair value estimated by the corresponding multi-path cash flow model utilized by the independent valuation firm.

(3)Represents Residual Profit Interests in Real Estate Investments.

(4)The weighted average information is generally derived by assigning each disclosed unobservable input a proportionate weight based on the fair value of the related investment.

The ranges of unobservable inputs used in the fair value measurement of our Level 3 investments as of June 30, 2024 were as follows:

(1)Represents the fair value of investments held by NPRC (see National Property REIT Corp section below) through its wholly owned subsidiaries, American Consumer Lending Limited (“ACLL”) and National General Lending Limited (“NGL”), and valued using a discounted cash flow valuation technique.

(2)Represents the implied discount rate based on our internally generated single-cash flow model that is derived from the fair value estimated by the corresponding multi-path cash flow model utilized by the independent valuation firm.

(3)Represents Residual Profit Interests in Real Estate Investments.

(4)The weighted average information is generally derived by assigning each disclosed unobservable input a proportionate weight based on the fair value of the related investment. For the Loss-adjusted discount rate and Projected loss rate unobservable inputs of investments represented in (1), the weighted average is determined based on the purchase yield of recently issued loans within each respective term-grade cohort.

Investments for which market quotations are readily available are valued at such market quotations. In order to validate market quotations, management and the independent valuation firm look at a number of factors to determine if the quotations are representative of fair value, including the source and nature of the quotations. These investments are classified as Level 1 or Level 2 in the fair value hierarchy.

The fair value of debt investments specifically classified as Level 2 in the fair value hierarchy are generally valued by an independent pricing agent or more than one principal market maker, if available, otherwise a principal market maker or a primary market dealer. We generally value over-the-counter securities by using the prevailing bid and ask prices from dealers during the relevant period end, which were provided by an independent pricing agent and screened for validity by such service.

In determining the range of values for debt instruments where market quotations are not readily available, and are therefore classified as Level 3 in the fair value hierarchy, except CLOs and debt investments in controlling portfolio companies, management and the independent valuation firm estimated corporate and security credit ratings and identified corresponding yields to maturity for each loan from relevant market data. A discounted cash flow technique was then applied using the appropriate yield to maturity as the discount rate, to determine a range of values. In determining the range of values for debt investments of controlled companies and equity investments, the enterprise value was determined by applying a market approach such as using earnings before interest, taxes, depreciation and amortization (“EBITDA”) multiples, net income and/or book value multiples for similar guideline public companies and/or similar recent investment transactions and/or an income approach, such as the discounted cash flow technique. The enterprise value technique may also be used to value debt investments which are credit impaired. For stressed debt and equity investments, asset recovery analysis was used.

In determining the range of values for our investments in CLOs, the independent valuation firm uses a discounted multi-path cash flow model. The valuations were accomplished through the analysis of the CLO deal structures to identify the risk exposures from the modeling point of view as well as to determine an appropriate call date (i.e., expected maturity). These risk factors are sensitized in the multi-path cash flow model using Monte Carlo simulations, to generate probability-weighted (i.e., multi-path) cash flows for the underlying assets and liabilities. These cash flows are discounted using appropriate market discount rates, and relevant data in the CLO market and certain benchmark credit indices are considered, to determine the value of each CLO investment. In addition, we generate a single-path cash flow utilizing our best estimate of expected cash receipts, and assess the reasonableness of the implied discount rate that would be effective for the value derived from the corresponding multi-path cash flow model. These investments are classified as Level 3 in the fair value hierarchy.

The significant unobservable input used to value our investments based on the yield technique and discounted cash flow technique is the market yield (or applicable discount rate) used to discount the estimated future cash flows expected to be received from the underlying investment, which includes both future principal and interest/dividend payments. Increases or decreases in the market yield (or applicable discount rate) would result in a decrease or increase, respectively, in the fair value measurement. Management and the independent valuation firms consider the following factors when selecting market yields or discount rates: risk of default, rating of the investment and comparable company investments, and call provisions.

The significant unobservable inputs used to value our investments based on the EV analysis may include market multiples of specified financial measures such as EBITDA, revenue, net income, or book value of identified guideline public companies, implied valuation multiples from precedent M&A transactions, and/or discount rates applied in a discounted cash flow technique. The independent valuation firm identifies a population of publicly traded companies with similar operations and key attributes to that of the portfolio company. Using valuation and operating metrics of these guideline public companies and/or as implied by relevant precedent transactions, a range of multiples of the latest twelve months EBITDA, or other measure such as net income or book value, is typically calculated. The independent valuation firm utilizes the determined multiples to estimate the portfolio company’s EV generally based on the latest twelve months EBITDA of the portfolio company (or other meaningful measure). Increases or decreases in the multiple would result in an increase or decrease, respectively, in EV which would result in an increase or decrease in the fair value measurement of the debt of controlled companies and/or equity investment, as applicable. In certain instances, a discounted cash flow analysis may be considered in estimating EV, in which case, discount rates based on a weighted average cost of capital and application of the capital asset pricing model may be utilized.

The significant unobservable inputs used to value our private REIT investments based on the discounted cash flow analysis is the discount rate and terminal capitalization rate applied to projected cash flows of the underlying properties. Increases or decreases in the discount rate and terminal capitalization rate would result in a decrease or increase, respectively, in the fair value measurement.

Changes in market yields, discount rates, capitalization rates or EBITDA (or other) multiples, each in isolation, may change the fair value measurement of certain of our investments. Generally, an increase in market yields, discount rates or capitalization rates, or a decrease in EBITDA (or other) multiples may result in a decrease in the fair value measurement of certain of our investments.

Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of our investments may fluctuate from period to period. Additionally, the fair value of our investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that we may ultimately realize. Further, such investments are generally subject to legal and other restrictions on resale or otherwise are less liquid than publicly traded securities. If we were required to liquidate a portfolio investment in a forced or liquidation sale, wecould realize significantly less than the value at which we have recorded it.

In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the unrealized gains or losses reflected in the currently assigned valuations.

Unconsolidated Significant Subsidiaries

Our investments are generally in small and mid-sized companies in a variety of industries. In accordance with Regulation S-X 3-09 and Regulation S-X 4-08(g), we must determine which of our unconsolidated controlled portfolio companies are considered “significant subsidiaries,” if any, as defined in Rule 1-02(w)(2) for BDC’s and closed end investment companies. Regulation S-X 3-09 requires separate audited financial statements of an unconsolidated subsidiary in an annual report. Regulation S-X 4-08(g) requires summarized financial information in an annual report.

NPRC is a significant subsidiary due to income for the years ended June 30, 2024 and June 30, 2023 requiring we include the audited consolidated financial statements of NPRC for the years ended December 31, 2024 and December 31, 2023 as Exhibit 99.1 and years ended December 31, 2022 and December 31, 2021 as Exhibit 99.2.

(1) The fiscal year end of the portfolio company is December 31st compared to PSEC’s June 30th fiscal year end. All amounts are unaudited.

Note 4. Revolving Credit Facility

On May 15, 2007, we formed our wholly owned subsidiary, PCF, a Delaware limited liability company and a bankruptcy remote special purpose entity, which holds certain of our portfolio loan investments that are used as collateral for the revolving credit facility at PCF. Since origination of the revolving credit facility, we have renegotiated the terms and extended the commitments of the revolving credit facility several times. Most recently, effective June 28, 2024, we completed an extension and upsizing of the revolving credit facility (the “Revolving Credit Facility”). The lenders have extended commitments of $2,121,500 as of June 30, 2025. The Revolving Credit Facility includes an accordion feature which allows commitments to be increased up to $2,250,000 in the aggregate. The extension and upsizing of the Revolving Credit Facility extended the maturity date to June 28, 2029 and the revolving period through June 28, 2028, followed by an additional one-year amortization period, with distributions allowed to Prospect after the completion of the revolving period. During such one-year amortization period, all principal payments on the pledged assets will be applied to reduce the balance. At the end of the one-year amortization period, the remaining balance will become due.

The Revolving Credit Facility contains restrictions pertaining to the geographic and industry concentrations of funded loans, maximum size of funded loans, interest rate payment frequency of funded loans, maturity dates of funded loans and minimum equity requirements, among other items. The Revolving Credit Facility also contains certain requirements relating to portfolio performance, including required minimum portfolio yield and limitations on delinquencies and charge-offs, violation of which could result in the early termination of the Revolving Credit Facility. As of June 30, 2025, we were in compliance with the applicable covenants of the Revolving Credit Facility.

The interest rate on borrowings under the Revolving Credit Facility is one-month SOFR plus 205 basis points. Additionally, the lenders charge a fee on the unused portion of the revolving credit facility amount equal to either 40 basis points if more than 60% of the revolving credit facility amount is drawn,70 basis points if more than 35% and an amount less than or equal to 60% of the revolving credit facility amount is drawn, or 150 basis points if an amount less than or equal to 35% of the revolving credit facility amount is drawn. The Revolving Credit Facility requires us to pledge assets as collateral in order to borrow under the Revolving Credit Facility. As of June 30, 2025, the investments, including cash and cash equivalents, used as collateral for the Revolving Credit Facility, had an aggregate fair value of $2,554,129, which represents 38.0% of our total investments, including cash and cash equivalents. These assets are held and owned by PCF, a bankruptcy remote special purpose entity, and, as such, these investments are not available to our general creditors. As additional eligible investments are transferred to PCF and pledged under the Revolving Credit Facility, PCF will generate additional availability up to the current commitment amount of $2,121,500. The release of any assets from PCF requires the approval of the facility agent.

For the year ended June 30, 2025, and June 30, 2024, the average stated interest rate (i.e., rate in effect plus the spread) and average outstanding borrowings for the Revolving Credit Facility were as follows:

As of June 30, 2025 and June 30, 2024, we had $570,532 and $830,124, respectively, available to us for borrowing under the Revolving Credit Facility, net of $856,322 and $794,796 outstanding borrowings as of the respective balance sheet dates.

In connection with the origination and amendments of the Revolving Credit Facility, we incurred $38,278 of fees, all of which are being amortized over the term of the facility. As of June 30, 2025 and June 30, 2024, $18,842 and $22,975, respectively, of the fees remain to be amortized and is reflected as deferred financing costs on the Consolidated Statements of Assets and Liabilities.

During the years ended June 30, 2025, 2024, and 2023, we recorded $68,300, $87,585, and $64,851, respectively, of interest costs, unused fees and amortization of financing costs on the Revolving Credit Facility as interest expense.

Note 5. Convertible Notes

2022 Notes

On April 11, 2017, we issued $225,000 aggregate principal amount of convertible notes that matured on July 15, 2022 (the “Original 2022 Notes”), unless previously converted or repurchased in accordance with their terms. The Original 2022 Notes bore interest at a rate of 4.95% per year, payable semi-annually on January 15 and July 15 each year, beginning July 15, 2017. Total proceeds from the issuance of the Original 2022 Notes, net of underwriting discounts and offering costs, were $218,010. On May 18, 2018, we issued an additional $103,500 aggregate principal amount of convertible notes that matured on July 15, 2022 (the “Additional 2022 Notes,” and together with the Original 2022 Notes, the “2022 Notes”), unless previously converted or repurchased in accordance with their terms.

We will settle any Holder Optional Conversion by paying or delivering, as the case may be, (A) any portion of the Settlement Amount (as defined below) that we elect to pay in cash and (B) a number of shares of our common stock at a conversion rate equal to (1) (a) the Settlement Amount, minus (b) any portion of the Settlement Amount that we elect to pay in cash, divided by (2) the arithmetic average of the daily volume weighted average price of shares of our common stock over each of thefive consecutive trading days ending on the Holder Conversion Exercise Date (such arithmetic average, the “5-day VWAP”). For the Series A1 Preferred Stock, the Series A3 Preferred Stock, the Series AA1 Preferred Stock, the Series AA2 Preferred Stock and the Series A2 Preferred Stock, “Settlement Amount” means (A) $25.00 per share (the “Stated Value”), plus (B) unpaid dividends accrued to, but not including, the Holder Conversion Exercise Date, minus (C) the applicable Holder Optional Conversion Fee for the respective Holder Conversion Deadline. For the Series M Preferred Stock, “Settlement Amount” means (A) the Stated Value, plus (B) unpaid dividends accrued to, but not including, the Holder Conversion Exercise Date, minus (C) the applicable Series M Clawback, if any. “Series M Clawback”, if applicable, means an amount equal to the aggregate amount of all dividends, whether paid or accrued, on such share of Series M stock in the three full months prior to the Holder Conversion Exercise Date. Subject to certain limited exceptions, we will not pay any portion of the Settlement Amount in cash (other than cash in lieu of fractional shares of our common stock) until thefive year anniversary of the date on which a share of 5.50% Preferred Stock or 6.50% Preferred Stock has been issued. Beginning on thefive year anniversary of the date on which a share of 5.50% Preferred Stock or 6.50% Preferred Stock is issued, we may elect to settle all or a portion of any Holder Optional Conversion in cash without limitation or restriction. The right of holders to convert a share of 5.50% Preferred Stock or 6.50% Preferred Stock will terminate upon the listing of such share on a national securities exchange. Shares of the Floating Rate Preferred Stock and 7.50% Preferred Stock do not have a Holder Optional Conversion feature.

Subject to certain limited exceptions allowing earlier redemption, beginning on the earlier of thefive year anniversary of the date on which a share of 5.50% Preferred Stock or 6.50% Preferred Stock has been issued, or thetwo year anniversary of the date on which a share of Floating Rate Preferred Stock or 7.50% Preferred Stock has been issued or, for listed shares of 5.50% Preferred Stock or 6.50% Preferred Stock, five years from the earliest date on which any series that has been listed was first issued and for listed shares of Floating Rate Preferred Stock or 7.50% Preferred Stock, two years from the earliest date on which any series that has been listed was first issued (the earlier of such dates as applicable to a series of Preferred Stock, the “Redemption Eligibility Date”), such share of Preferred Stock may be redeemed at any time or from time to time at our option (the “Issuer Optional Redemption”), at a redemption price of 100% of the Stated Value of the shares to be redeemed plus unpaid dividends accrued to, but not including, the date fixed for redemption.

Shares of the Floating Rate Preferred Stock and 7.50% Preferred Stock are redeemable, at the option of the holder of such Floating Rate Preferred Stock and 7.50% Preferred Stock, on a monthly basis (the “Holder Optional Redemption”). For all shares of Floating Rate Preferred Stock and 7.50% Preferred Stock duly submitted for redemption on or before a monthly Holder Redemption Deadline (defined in the prospectus supplement dated December 29, 2023), the HOR Settlement Amount (as defined below) is determined on any business day after such Holder Redemption Deadline but before the Holder Redemption Deadline occurring two months thereafter (such date, the “Holder Redemption Exercise Date”). Within such period, we may select the Holder Redemption Exercise Date in our sole discretion. We will settle any Holder Optional Redemption by paying the HOR Settlement Amount in cash.

The aggregate amount of Holder Optional Redemptions by the holder of Floating Rate Preferred Stock is subject to the following redemption limits: (i) no more than 2% of the outstanding Floating Rate Preferred Stock, in aggregate, as of the end of the most recent fiscal quarter will be redeemed per calendar month; (ii) no more than 5% of the outstanding Floating Rate Preferred Stock, in aggregate, as of the end of the most recent fiscal quarter will be redeemed per fiscal quarter and (iii) no more than 20% of the outstanding Floating Rate Preferred Stock, in aggregate, as of the end of the most recent fiscal quarter will be redeemed per Annual Redemption Period. Redemption capacity of the Floating Rate Preferred Stock will be allocated on a pro rata basis based on the number of shares of Floating Rate Preferred Stock, as applicable, submitted in the event that a monthly redemption is oversubscribed, based on any of the foregoing redemption limits.

The aggregate amount of Holder Optional Redemptions by the holders of 7.50% Preferred Stock is subject to the following redemption limits: (i) no more than 2% of the outstanding 7.50% Preferred Stock, in aggregate, as of the end of the most recent fiscal quarter will be redeemed per calendar month; (ii) no more than 5% of the outstanding 7.50% Preferred Stock, in aggregate, as of the end of the most recent fiscal quarter will be redeemed per fiscal quarter; and (iii) no more than 20% of the outstanding 7.50% Preferred Stock, in aggregate, as of the end of the most recent fiscal quarter will be redeemed per Annual Redemption Period; plus, for each redemption limit set forth above in clauses (i) through (iii) of this paragraph, an amount of such 7.50% Preferred Stock equal to the lowest excess, if any, between the corresponding applicable 2% /5% /20% redemption limits for Floating Rate Preferred Stock as set forth above and the respective amounts requested for the Floating Rate Preferred Stock on a Holder Redemption Deadline for the Floating Rate Preferred Stock.

Additionally, we have covenanted to waive the applicable 2% /5% /20% redemption limits for the Floating Rate Preferred Stock as set forth in the terms of the Floating Rate Preferred Stock such that holders of the Floating Rate Preferred Stock may, in addition to the amount of Floating Rate Preferred Stock such holders are entitled to redeem pursuant to the terms of the Floating Rate Preferred Stock, also redeem an amount of such Floating Rate Preferred Stock equal to the lowest excess, if any, between the corresponding applicable 2% /5% /20% redemption limits for the 7.50% Preferred Stock as set forth in the terms of the 7.50% Preferred Stock and the respective amounts requested for the 7.50% Preferred Stock on a Holder Redemption Deadline for the 7.50% Preferred Stock.

Redemption capacity of the 7.50% Preferred Stock will be allocated on a pro rata basis based on the number of 7.50% Preferred Stock, as applicable, submitted in the event that a monthly redemption is oversubscribed based on any of the foregoing redemption limits.

An “Annual Redemption Period” means our then current fiscal quarter and the three fiscal quarters immediately preceding our then current fiscal quarter. Shares of Series A4 Preferred Stock and Series A5 Preferred Stock are subject to an early redemption fee if it is redeemed by its holder within five years of issuance. We may waive the foregoing redemption limits in our sole discretion at any time.

For the Series A4 Preferred Stock and Series A5 Preferred Stock, “HOR Settlement Amount” means (A) the stated value, plus (B) unpaid dividends accrued to, but not including, the Holder Redemption Exercise Date, minus (C) the Series A4 Preferred Stock or Series A5 Preferred Stock Holder Optional Redemption fee, as applicable on the respective Holder Redemption Deadline.

For the Series M4 Preferred Stock and Series M5 Preferred Stock, “HOR Settlement Amount” means (A) the stated value, plus (B) unpaid dividends accrued to, but not including, the Holder Redemption Exercise Date, but if a holder of Series M4 Preferred Stock or Series M5 Preferred Stock exercises a Holder Optional Redemption within the first twenty-four months of issuance of such Series M4 Preferred Stock or Series M5 Preferred Stock, the HOR Settlement Amount payable to such holder will be reduced by (i) during the first twelve months of issuance of such Series M4 Preferred Stock or Series M5 Preferred Stock, the aggregate amount of all dividends, whether paid or accrued, on such Series M4 Preferred Stock or Series M5 Preferred Stock, respectively, in the six-month period prior to the Holder Redemption Exercise Date, and (ii) during the second twelve months of issuance of such Series M4 Preferred Stock or Series M5 Preferred Stock, the aggregate amount of all dividends, whether paid or accrued, on such Series M4 Preferred Stock or Series M5 Preferred Stock in the three-month period prior to the Holder Redemption Exercise Date (such amount, the “Series M4 Shares Clawback” and “Series M5 Shares Clawback,” respectively). We are permitted to waive the Series M4 Shares Clawback and Series M5 Shares Clawback through public announcement of the terms and duration of such waiver. Any such waiver would apply to any holder of Preferred Stock qualifying for the waiver and exercising a Holder Optional Redemption during the pendency of the term of such waiver. Although we have retained the right to waive the Series M4 Shares Clawback and Series M5 Shares Clawback in the manner described above, we are not required to establish any such waivers and we may never establish any such waivers.

Subject to certain limitations, each share of 5.50% Preferred Stock or 6.50% Preferred Stock may be converted at our option (the “Issuer Optional Conversion”). We will settle any Issuer Optional Conversion by paying or delivering, as the case may be, (A) any portion of the IOC Settlement Amount (as defined below) that we elect to pay in cash and (B) a number of shares of our common stock at a conversion rate equal to (1) (a) the IOC Settlement Amount, minus (b) any portion of the IOC Settlement Amount that we elect to pay in cash, divided by (2) the 5-day VWAP, subject to our ability to obtain or maintain any stockholder approval that may be required under the 1940 Act to permit us to sell our common stock below net asset value if the 5-day VWAP represents a discount to our net asset value per share of common stock. For the 5.50% Preferred Stock and 6.50% Preferred Stock, “IOC Settlement Amount” means (A) the Stated Value, plus (B) unpaid dividends accrued to, but not including, the date fixed for conversion. In connection with an Issuer Optional Conversion, we will use commercially reasonable efforts to obtain or maintain any stockholder approval that may be required under the 1940 Act to permit us to sell our common stock below net asset value. If we do not have or obtain any required stockholder approval under the 1940 Act to sell our common stock below net asset value and the 5-day VWAP is at a discount to our net asset value per share of common stock, we will settle any conversions in connection with an Issuer Optional Conversion by paying or delivering, as the case may be, (A) any portion of the IOC Settlement Amount that we elect to pay in cash and (B) a number of shares of our common stock at a conversion rate equal to (1) (a) the IOC Settlement Amount, minus (b) any portion of the IOC Settlement Amount that we elect to pay in cash, divided by (2) the NAV per share of common stock at the close of business on the business day immediately preceding the date of conversion. We will not pay any portion of the IOC Settlement Amount from an Issuer Optional Conversion in cash (other than cash in lieu of fractional shares of our common stock) until the Redemption Eligibility Date. Beginning on the Redemption Eligibility Date, we may elect to settle any Issuer Optional Conversion in cash without limitation or restriction. In the event that we exercise an Issuer Optional Conversion with respect to any shares of 5.50% Preferred Stock or 6.50% Preferred Stock, the holder of such 5.50% Preferred Stock or 6.50% Preferred Stock may instead elect a Holder Optional Conversion with respect to such 5.50% Preferred Stock or 6.50% Preferred Stock provided that the date of conversion for such Holder Optional Conversion would occur prior to the date of conversion for an Issuer Optional Conversion. Shares of the Floating Rate Preferred Stock and 7.50% Preferred Stock do not have an Issuer Optional Conversion feature. The Company actively manages its offerings of preferred stock and, although it may or may not be presently offering a particular series of its preferred stock, the Company may determine to issue any of its authorized series of preferred stock (and, in connection therewith, to relaunch the offering of any particular series, if previously terminated) based on its assessment of market conditions, demand, and appropriate cost of capital in light of the foregoing and the overall construction of its portfolio and capital structure.

On July 12, 2021, we entered into an underwriting agreement by and among us, Prospect Capital Management L.P., Prospect Administration LLC, and Morgan Stanley & Co. LLC, RBC Capital Markets, LLC and UBS Securities LLC, as representatives of the underwriters, relating to the offer and sale of 6,000,000 shares, or $150,000 in aggregate liquidation preference, of our 5.35% Series A Fixed Rate Cumulative Perpetual Preferred Stock, par value $0.001 per share (the “Series A Preferred Stock” or “5.35% Preferred Stock”), at a public offering price of $25.00 per share. Pursuant to the Underwriting Agreement, we also granted the underwriters a 30-day option to purchase up to an additional 900,000 shares of Series A Preferred Stock solely to cover over-allotments. The offer settled on July 19, 2021, and no additional shares of the Series A Preferred Stock were issued pursuant to the option. In connection with such offering, on July 15, 2021, we filed Articles Supplementary with SDAT, reclassifying and designating 6,900,000 shares of the Company’s authorized and unissued shares of Common Stock into shares of Series A Preferred Stock.

Each series of 5.50% Preferred Stock,6.50% Preferred Stock, Floating Rate Preferred Stock,7.50% Preferred Stock and Series A Preferred Stock ranks (with respect to the payment of dividends and rights upon liquidation, dissolution or winding up) (a) senior to our common stock, (b) on parity with each other series of our preferred stock, and (c) junior to our existing and future secured and unsecured indebtedness. See Note 8. Fair Value and Maturity of Debt Outstanding for further discussion on our senior securities.

We may from time to time seek to cancel or purchase our outstanding preferred stock through cash purchases and/or exchanges, in open market purchases, privately negotiated transactions or otherwise. The amounts involved may be material. Any such purchases or exchanges of preferred stock would be subject to prevailing market conditions, our liquidity requirements, contractual and regulatory restrictions and other factors. On June 16, 2022, our Board of Directors authorized the repurchase of up to 1.5 million shares our Series A Preferred Stock and further on October 11, 2023, authorized any and all outstanding Series A Preferred Stock to be repurchased. The manner, price, volume and timing of preferred share repurchases are subject to a variety of factors, including market conditions and applicable SEC rules.

During the year ended June 30, 2024, we repurchased 80,303 shares of Series A Preferred Stock for a total cost of approximately $1,279, including fees and commissions paid to the broker, representing an average repurchase price of $15.76 per share. The difference in the consideration transferred and the net carrying value of the Series A Preferred Stock repurchased, which was $1,937, resulted in a gain applicable to common stock holders of approximately $657 during the year ended June 30, 2024. The repurchased shares reverted to authorized but unissued shares of Series A Preferred Stock and thus the Company holds no treasury stock.

During the year ended June 30, 2025, we didnot repurchase shares of Series A Preferred Stock.

On October 30, 2023, we commenced a tender offer (the “Series A Preferred Stock Tender Offer”) to purchase for cash any and all of 5,882,351 shares of outstanding Series A Preferred Stock at a price of $15.88, plus accrued and unpaid dividends for a total consideration of $16.00 per share. The Series A Preferred Stock Tender Offer expired at 5:00 p.m., New York City time, on November 29, 2023 and as a result, $15,780 aggregate liquidation amount of the Series A Preferred Stock were validly tendered and accepted, and we recognized a realized gain of $5,197 from the purchase of 631,194 shares of Series A Preferred Stock in the amount of the difference between the consideration transferred and the net carrying amount of the Series A Preferred Stock.

During the year ended June 30, 2024, we exchanged an aggregate of 901,755 Series M1 Preferred Stock for an aggregate of 348,125 and 553,630 newly-issued Series M3 Preferred Stock and Series M4 Preferred Stock, respectively, pursuant to Section 3(a)(9) of the Securities Act. During the year ended June 30, 2024, we exchanged an aggregate of 338,068 Series M3 Preferred Stock for an aggregate of 338,068 newly-issued Series M4 Preferred Stock pursuant to the Securities Act. The Series M3 Preferred Stock and Series M4 Preferred Stock issued in the exchanges were issued in each case to an existing security holder of the Company exclusively in exchange for such holder’s securities. No commission or other remuneration was paid or given for soliciting the exchange. Stockholders who exchange Series M1 Preferred Stock for Series M3 Preferred Stock or Series M4 Preferred Stock or Series M3 Preferred Stock for Series M4 Preferred Stock will receive unpaid dividends on their Series M1 Preferred Stock or Series M3 Preferred Stock accrued to, but not including, the Exchange Exercise Date in cash. Upon settlement, the carrying amount (including any premiums or discounts and a proportional amount of any issuance costs) of the Series M1 Preferred Stock or Series M3 Preferred Stock are reclassified to Series M3 Preferred Stock or Series M4 Preferred stock, respectively, with no gain or loss recognized.

During the year ended June 30, 2025, we exchanged an aggregate of 195,938 Series M1 Preferred Stock for an aggregate of 10,842,142,054, and 43,040 newly-issued Series M3 Preferred Stock, Series M4 Preferred Stock, and Series M5 Preferred Stock respectively. Additionally during the year ended June 30, 2025, we exchanged an aggregate of 294,040 Series M3 Preferred Stock for an aggregate of 266,878 and 27,160 newly-issued Series M4 Preferred Stock and newly-issued Series M5 Preferred Stock, respectively, pursuant to Section 3(a)(9) of the Securities Act.

The Series M3 Preferred Stock, Series M4 Preferred Stock, and Series M5 Preferred Stock issued in the exchanges were issued in each case to an existing security holder of the Company exclusively in exchange for such holder’s securities. No commission or other remuneration was paid or given for soliciting the exchange. Stockholders who exchange Series M1 Preferred Stock for Series M3 Preferred Stock or Series M4 Preferred Stock or Series M3 Preferred Stock for Series M4 Preferred Stock or Series M5 Preferred Stock will receive unpaid dividends on their Series M1 Preferred Stock or Series M3 Preferred Stock accrued to, but not including, the Exchange Exercise Date, plus any fractional amount of a Series M1 Preferred Stock or Series M3 Preferred Stock exchanged multiplied by $25.00 in cash. Upon settlement, the carrying amount (including any premiums or discounts and a proportional amount of any issuance costs) of the Series M1 Preferred Stock or Series M3 Preferred Stock are reclassified to Series M3 Preferred Stock, Series M4 Preferred Stock, or Series M5 Preferred Stock, respectively, with no gain or loss recognized.

Subject to certain limited exceptions allowing earlier redemption, at any time after the close of business on July 19, 2026 (any such date, an “Optional Redemption Date”), at our sole option, we may redeem the Series A Preferred Stock in whole or, from time to time, in part, out of funds legally available for such redemption, at a price per share equal to the liquidation preference of $25.00 per share, plus an amount equal to all unpaid dividends on such shares (whether or not earned or declared, but excluding interest thereon) accumulated up to, but excluding, the date fixed for redemption. We may also redeem the Series A Preferred Stock at any time, in whole or, from time to time, in part, including prior to the Optional Redemption Date, pro rata, based on liquidation preference, with all other series of our then outstanding preferred stock, in the event that our Board of Directors determines to redeem any series of our preferred stock, in whole or, from time to time, in part, because such redemption is deemed necessary by our Board of Directors to comply with the asset coverage requirements of the 1940 Act or for us to maintain RIC status.

In the event of a Change of Control Triggering Event (as defined below), we may, at our option, exercise our special optional redemption right to redeem the Series A Preferred Stock, in whole or in part, within 120 days after the first date on which such Change of Control Triggering Event has occurred by paying the liquidation preference, plus an amount equal to all unpaid dividends on such shares (whether or not earned or declared, but excluding interest thereon) accumulated up to, but excluding, the date fixed for such redemption. To the extent that we exercise our optional redemption right or our special optional redemption right relating to the Series A Preferred Stock, the holders of Series A Preferred Stock will not be permitted to exercise the conversion right described below in respect of their shares called for redemption.

Except to the extent that we have elected to exercise our optional redemption right or our special optional redemption right by providing notice of redemption prior to the Change of Control Conversion Date (as defined below), upon the occurrence of a Change of Control Triggering Event, each holder of Series A Preferred Stock will have the right to convert some or all of the Series A Preferred Stock held by such holder on the Change of Control Conversion Date into a number of our shares of common stock per Series A Preferred Stock to be converted equal to the lesser of:

•the quotient obtained by dividing (i) the sum of the Liquidation Preference per share plus an amount equal to all unpaid dividends thereon (whether or not earned or declared, but excluding interest thereon) accumulated up to, but excluding, the Change of Control Conversion Date (unless the Change of Control Conversion Date is after a Record

Date for a Series A Preferred Stock dividend payment and prior to the corresponding Series A Preferred Stock dividend payment date, in which case no additional amount for such accrued and unpaid dividends will be included in this sum) by (ii) the Common Stock Price (as defined below); and

•6.03865, subject to certain adjustments,

subject, in each case, to provisions for the receipt of alternative consideration upon conversion as described in the applicable prospectus supplement.

If we have provided or provide a redemption notice with respect to some or all of the Series A Preferred Stock, holders of any Series A Preferred Stock that we have called for redemption will not be permitted to exercise their Change of Control Conversion Right in respect of any of their Series A Preferred Stock that have been called for redemption, and any Series A Preferred Stock subsequently called for redemption that have been tendered for conversion will be redeemed on the applicable date of redemption instead of converted on the Change of Control Conversion Date.

For purposes of the foregoing discussion of a redemption upon the occurrence of a Change of Control Triggering Event, the following definitions are applicable:

“Change of Control Triggering Event” means the occurrence of any of the following:

•the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation and other than an Excluded Transaction) in one or a series of related transactions, of all or substantially all of the assets of the Company and its Controlled Subsidiaries taken as a whole to any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) (other than to any Permitted Holders); provided that, for the avoidance of doubt, a pledge of assets pursuant to any of our secured debt instruments or the secured debt instruments of our Controlled Subsidiaries shall not be deemed to be any such sale, lease, transfer, conveyance or disposition; or

•the consummation of any transaction (including, without limitation, any merger or consolidation and other than an Excluded Transaction) the result of which is that any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) (other than any Permitted Holders) becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of our outstanding Voting Stock, measured by voting power rather than number of shares.

Notwithstanding the foregoing, the consummation of any of the transactions referred to in the bullet points above will not be deemed a Change of Control Triggering Event if we or the acquiring or surviving consolidated entity has or continues to have a class of common securities (or ADRs representing such securities) listed on the NYSE, the NYSE American or NASDAQ, or listed or quoted on an exchange or quotation system that is a successor to the NYSE, the NYSE American or NASDAQ, or is otherwise listed or quoted on a national securities exchange.

The “Change of Control Conversion Date” is the date the shares of Series A Preferred Stock are to be converted, which will be a business day selected by us that is no fewer than 20 days nor more than 35 days after the date on which we provide the notice described above to the holders of Series A Preferred Stock.

The “Common Stock Price” will be (i) if the consideration to be received in the Change of Control Triggering Event by the holders of our common stock is solely cash, the amount of cash consideration per share of our common stock or (ii) if the consideration to be received in the Change of Control Triggering Event by holders of our common stock is other than solely cash (x) the average of the closing sale prices per share of our common stock (or, if no closing sale price is reported, the average of the closing bid and ask prices or, if more than one in either case, the average of the average closing bid and the average closing ask prices) for the ten consecutive trading days immediately preceding, but not including, the effective date of the Change of Control Triggering Event as reported on the principal U.S. securities exchange on which our common stock is then traded, or (y) the average of the last quoted bid prices for our common stock in the over-the-counter market as reported by OTC Markets Group Inc. or similar organization for the ten consecutive trading days immediately preceding, but not including, the effective date of the Change of Control Triggering Event, if our common stock is not then listed for trading on a U.S. securities exchange.

“Controlled Subsidiary” means any of our subsidiaries, 50% or more of the outstanding equity interests of which are owned by us and our direct or indirect subsidiaries and of which we possess, directly or indirectly, the power to direct or cause the direction of the management or policies, whether through the ownership of voting equity interests, by agreement or otherwise.

“Excluded Transaction” means (i) any transaction that does not result in any reclassification, conversion, exchange or cancellation of all or substantially all of the outstanding shares of our Voting Stock; (ii) any changes resulting from a subdivision or combination or a change solely in par value; (iii) any transaction where the shares of our Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving “person” (as that term is used in Section 13(d)(3) of the Exchange Act) or any direct or indirect parent company of the surviving “person” (as that term is used in Section 13(d)(3) of the Exchange Act) immediately after giving effect to such transaction; (iv) any transaction if (A) we become a direct or indirect wholly-owned subsidiary of a holding company and (B)(1) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of our Voting Stock immediately prior to that transaction or (2) immediately following that transaction no “person” (as that term is used in Section 13(d)(3) of the Exchange Act) is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company; or (v) any transaction primarily for the purpose of changing our jurisdiction of incorporation or form of organization.

“Permitted Holders” means (i) us, (ii) one or more of our Controlled Subsidiaries and (iii) Prospect Capital Management or any affiliate of Prospect Capital Management that is organized under the laws of a jurisdiction located in the United States of America and in the business of managing or advising clients.

“Voting Stocks” as applied to stock of any person, means shares, interests, participations or other equivalents in the equity interest (however designated) in such person having ordinary voting power for the election of the directors (or the equivalent) of such person, other than shares, interests, participations or other equivalents having such power only by reason of the occurrence of a contingency.

Except as provided above in connection with a Change of Control Triggering Event, the Series A Preferred Stock is not convertible into or exchangeable for any other securities or property.

For so long as the Series A Preferred Stock, the Floating Rate Preferred Stock, or 7.50% Preferred Stock are outstanding, we will not exercise any option we have to convert any other series of our outstanding preferred stock to common stock, including the Issuer Optional Conversion, or any other security ranking junior to such preferred stock. As a result, if dividends on the Preferred Stock have accumulated and been unpaid for a period oftwo years, a possibility of redemption outside of the Company’s control exists and, in accordance with ASC 480, we have presented our 5.50% Preferred Stock,6.50% Preferred Stock, and Series A Preferred Stock within temporary equity on our Consolidated Statement of Assets and Liabilities as of June 30, 2025 and June 30, 2024.

The Floating Rate Preferred Stock and 7.50% Preferred Stock are redeemable at the election of the holder at any time; therefore, is probable of redemption outside of the Company’s control. As a result, the Floating Rate Preferred Stock and 7.50% Preferred Stock are classified within temporary equity on our Consolidated Statement of Assets and Liabilitiesas of June 30, 2025 and are accreted to redemption value upon issuance. Accretion to redemption value is treated as an adjustment to net increase (decrease) in net assets resulting from operations applicable to common stockholders on our Consolidated Statement of Operations.

Shares of the 5.50% Preferred Stock,6.50% Preferred Stock, and 7.50% Preferred Stock will pay a monthly dividend, when and if declared by our Board of Directors, at a fixed annual rate of 5.50%,6.50%, and 7.50%, respectively, per annum of the Stated Value of $25.00 per share (computed on the basis of a 360-day year consisting oftwelve 30-day months), payable in cash or through the issuance of additional 5.50% Preferred Stock,6.50% Preferred Stock, and 7.50% Preferred Stock through the 5.50% Preferred Stock DRIP,6.50% Preferred Stock DRIP, and 7.50% Preferred Stock DRIP, respectively.

Shares of the Floating Rate Preferred Stock will pay a monthly dividend, when, and if authorized by, or under authority granted by, our Board of Directors, and declared by us out of funds legally available therefor, at an annualized floating rate equal to one-month Term SOFR (as defined in the Prospectus Supplement dated December 29, 2023) plus 2.00%, subject to a minimum annualized dividend rate of 6.50% (the “Cap Rate”) and a maximum annualized dividend rate of 8.00%, each with respect to the stated value of $25.00 per share of the Floating Rate Preferred Stock (computed on the basis of a 360-day year consisting oftwelve 30-day months), payable in cash or through the issuance of additional Floating Rate Preferred Stock through the Floating Rate Preferred Stock DRIP. The floating dividend rate on the Floating Rate Preferred Stock will reset upon each dividend authorization by our Board of Directors, and will reset to the applicable rate as determined two U.S. Government Securities Business Days (as defined in the Prospectus Supplement dated December 29, 2023) prior to such authorization, as adjusted for the terms herein. The applicable floating dividend rate on the Floating Rate Preferred Stock is presently expected to reset approximately once every three months.

Shares of the Series A Preferred Stock will pay a quarterly dividend, when and if declared by our Board of Directors, at a fixed annual rate of 5.35% per annum of the Stated Value of $25.00 per share (computed on the bases of a 360-day year consisting oftwelve 30-day months), payable in cash.

The below distributions to our Preferred Stockholders are net of any Series M Clawback applied to Series M stock through either the Holder Optional Conversion or Holder Optional Redemption of such Series M shares.

Common Stock

Our common stockholders’ equity accounts as of June 30, 2025 and June 30, 2024 reflect cumulative shares issued, net of shares previously repurchased, as of those respective dates. Our common stock has been issued through public offerings, a registered direct offering, the exercise of over-allotment options on the part of the underwriters, our common stock dividend reinvestment plan in connection with the acquisition of certain controlled portfolio companies and in connection with our 5.50% and 6.50% Preferred Stock Holder Optional Conversion and Optional Redemptions Following Death of a Holder. When our common stock is issued, the related offering expenses have been charged against paid-in capital in excess of par. All underwriting fees and offering expenses were borne by us.

On August 24, 2011, our Board of Directors approved a share repurchase plan (the “Repurchase Program”), pursuant to which we may repurchase up to $100,000 of our common stock at prices below our net asset value per share. Prior to any repurchase, we are required to notify stockholders of our intention to purchase our common stock.

We didnot repurchase any shares of our common stock under the Repurchase Program for the year ended June 30, 2025 and June 30, 2024. As of June 30, 2025, the approximate dollar value of shares that may yet be purchased under the Repurchase Program is $65,860.

Excluding common stock dividend reinvestments and shares issued in connection with the 5.50% and 6.50% Preferred Stock Holder Optional Conversion and Optional Redemption Upon Death of Holder, during the year ended June 30, 2025 and June 30, 2024, we didnot issue any shares of our common stock.

On February 9, 2016, we amended our common stock dividend reinvestment plan that provided for reinvestment of our dividends or distributions on behalf of our stockholders, unless a stockholder elects to receive cash, to add the ability of stockholders to purchase additional common shares by making optional cash investments. Under the revised dividend reinvestment and direct common stock repurchase plan, stockholders may elect to purchase additional common shares through our transfer agent in the open market or in negotiated transactions.

On April 17, 2020, our Board of Directors approved further amendments to our common stock dividend reinvestment plan, effective May 21, 2020, that principally provide for the number of newly-issued shares of our common stock to be credited to a stockholder’s account shall be determined by dividing the total dollar amount of the distribution payable to such common stockholder by 95% of the market price per share of our common stock at the close of regular trading on the Nasdaq Global Select Market on the date fixed by our Board of Directors for such distribution (which shall be the last business day before the payment date).

On June 17, 2025 at a special meeting of stockholders, our stockholders authorized us to sell shares of our common stock (during the next 12 months) at a price or prices below our net asset value per share at the time of sale in one or more offerings, subject to certain conditions as set forth in the proxy statement relating to the special meeting (including that the number of shares sold on any given date does not exceed 25% of its outstanding common stock immediately prior to such sale).

During the year ended June 30, 2025 and June 30, 2024, we distributed approximately $264,059 and $297,633, respectively, to our common stockholders. The following table summarizes our distributions to common stockholders declared and payable for the year ended June 30, 2025 and June 30, 2024:

Dividends and distributions to common stockholders are recorded on the ex-dividend date. As such, the table above includes distributions with record dates during the year ended June 30, 2025 and June 30, 2024. It does not include distributions previously declared to common stockholders of record on any future dates, as those amounts are not yet determinable. The following dividends were previously declared and will be recorded and payable subsequent to June 30, 2025:

•$0.045 per share for July 2025 holders of record on July 29, 2025 with a payment date of August 20, 2025.

•$0.045 per share for August 2025 holders of record on August 27, 2025 with a payment date of September 18, 2025.

During the years ended June 30, 2025 and June 30, 2024, we issued 7,505,661 and 6,736,142 shares of our common stock, respectively, in connection with the common stock dividend reinvestment plan.

As of June 30, 2025, we have reserved 600,000,000, which is comprised of 500,000,000 shares of common stock issuable upon conversion of the 5.50% Preferred Stock and the 6.50% Preferred Stock, and 100,000,000 shares of common stock issuable to Common Stock Holders pursuant to our dividend reinvestment and direct stock purchase plans.

Note 10. Other Income

Other income consists of structuring fees, amendment fees, overriding royalty interests, receipts related to net profit and revenue interests, deal deposits, administrative agent fees, and other miscellaneous and sundry cash receipts. The following table shows income from such sources during the three years ended June 30, 2025, 2024, and 2023:

Note 11. Net Increase (Decrease) in Net Assets per Common Share

Basic earnings (loss) per share is calculated by dividing the net increase (decrease) in net assets resulting from operations, less preferred stock dividends plus net gain (loss) on repurchase and accretion to redemption value of redeemable preferred stock, by the weighted average number of common shares outstanding for that period. Diluted earnings (loss) per share gives effect to all dilutive potential common shares outstanding using the if-converted method for the 5.50% Preferred Stock, the 6.50% Preferred Stock (see Note 9) and for the year ended June 30, 2024, the 2025 Notes (see Note 5).

Diluted earnings per share excludes all dilutive potential common shares if their effect is anti-dilutive.

During the year ended June 30, 2025, conversion of our convertible instruments had an anti-dilutive effect and therefore, conversion is not assumed.

The following information sets forth the computation of basic and diluted earnings per common share during the years ended June 30, 2025, 2024, and 2023:

Note 12. Income Taxes

While our fiscal year end for financial reporting purposes is June 30 of each year, our tax year end is August 31 of each year. The information presented in this footnote is based on our tax year end for each period presented, unless otherwise specified.

The determination of tax character of distributions was not determinable at the end of the fiscal year end. Final determination of tax character of distributions will not be final until we file our return for the tax year. For income tax purposes, dividends paid and distributions made to stockholders are reported as ordinary income, capital gains, non-taxable return of capital, or a combination thereof. The tax character of dividends paid to common stockholders during the tax years ended August 31, 2024, 2023, and 2022 were as follows:

The Company began issuing shares of Preferred Stock and declaring dividends on shares Preferred Stock outstanding during the tax year ended August 31, 2021. The tax character of dividends paid to preferred stockholders during the tax years ended August 31, 2024, 2023, and 2022 were as follows:

As of August 28, 2024 when our prior Form 10-K was filed for the year ended June 30, 2024, we estimated our distributions for the fiscal year then ended to be $389,263 of distributions of ordinary income and $6,459 to be return of capital. Subsequent to our filing date, we obtained more information from our underlying investments as to the character of the distributions for the tax year ended August 31, 2024, which resulted in changes to distributions previously disclosed in our Form 10-K filing. As a result of the change, our total distributable loss on our Consolidated Statements of Assets and Liabilities for the year ended June 30, 2024 changed from $497,299 to $436,279, with $61,020 being reclassified to return of capital from ordinary income. The remaining reclassification of tax distributions classified as return of capital for the tax year ended August 31, 2024 have been adjusted in the fiscal year ended June 30, 2025. This adjustment results in an increase to distributable earnings of $10,394 for the fiscal year ended June 30, 2024.

For the tax year ending August 31, 2025, the tax character of distributions paid to stockholders through August 31, 2025 is expected to be ordinary income and return of capital. However, due to the difference between our fiscal and tax year ends, the final determination of the tax character of distributions between ordinary income and return of capital will not be made until we file our tax return for the tax year ending August 31, 2025.

Taxable income generally differs from net increase in net assets resulting from operations for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses, and generally excludes net unrealized gains or losses, as unrealized gains or losses are generally not included in taxable income until they are realized. The following reconciles the net increase in net assets resulting from operations to taxable income for the tax years ended August 31, 2024, 2023, and 2022:

(1) Temporary book-to-tax differences include timing recognition of CLO income, flow-through investment income/loss, and dividend income from portfolio companies

As of our most recent tax year ended August 31, 2024, we hadno undistributed ordinary income in excess of cumulative distributions andno capital gain in excess of cumulative distributions.

Capital losses in excess of capital gains earned in a tax year may generally be carried forward and used to offset capital gains, subject to certain limitations. As of our most recent tax year ended August 31, 2024, we had a capital loss carryforward of $397,259 available for use in later tax years.

As of June 30, 2025, the cost basis of investments for tax purposes was $6,800,692 resulting in an estimated net unrealized loss of $127,176. As of June 30, 2024, the cost basis of investments for tax purposes was $7,429,121 resulting in an estimated net unrealized gain of $289,122. As of June 30, 2025, the gross unrealized gains and losses were $1,308,011 and $1,435,187, respectively. As of June 30, 2024, the gross unrealized gains and losses were $1,381,820 and $1,092,698, respectively. Due to the difference between our fiscal year end and tax year end, the cost basis of our investments for tax purposes as of June 30, 2025 and June 30, 2024 was calculated based on the book cost of investments as of June 30, 2025 and June 30, 2024, respectively, with cumulative book-to-tax adjustments for investments through August 31, 2024 and 2023, respectively.

In general, we may make certain adjustments to the classification of net assets as a result of permanent book-to-tax differences, which may include merger-related items, differences in the book and tax basis of certain assets and liabilities, and nondeductible federal excise taxes, among other items. During the tax year ended August 31, 2024, we increased total distributable earnings by $63, decreased accumulated realized losses by $21,530, and decreased capital in excess of par value by $21,593. During the tax year ended August 31, 2023, we increased total distributable earnings by$27 andincreased accumulated realized losses by$622, and increased capital in excess of par value by$595. Due to the difference between our fiscal and tax year end, the reclassifications for the taxable year ended August 31, 2024, once finalized, were recorded in the fiscal year ending June 30, 2025 and the reclassifications for the taxable year ended August 31, 2023 were recorded in the fiscal year ended June 30, 2024.

Note 13. Related Party Agreements and Transactions

Investment Advisory Agreement

We have entered into an investment advisory and management agreement with the Investment Adviser (the “Investment Advisory Agreement”) under which the Investment Adviser, subject to the overall supervision of our Board of Directors, manages the day-to-day operations of, and provides investment advisory services to, us. Under the terms of the Investment Advisory Agreement, the Investment Adviser: (i) determines the composition of our portfolio, the nature and timing of the changes to our portfolio and the manner of implementing such changes, (ii) identifies, evaluates and negotiates the structure of the investments we make (including performing due diligence on our prospective portfolio companies), and (iii) closes and monitors investments we make.

The Investment Adviser’s services under the Investment Advisory Agreement are not exclusive, and it is free to furnish similar services to other entities so long as its services to us are not impaired. For providing these services the Investment Adviser receives a fee from us, consisting of two components: a base management fee and an incentive fee. The base management fee is calculated at an annual rate of 2.00% on our total assets. For services currently rendered under the Investment Advisory Agreement, the base management fee is payable quarterly in arrears. The base management fee is calculated based on the average value of our gross assets at the end of the two most recently completed calendar quarters and appropriately adjusted for any share issuances or repurchases during the current calendar quarter. The total gross base management fee incurred to the favor of the Investment Adviser was $145,756, $157,001, and $155,084, during the years ended June 30, 2025, 2024, and 2023, respectively.

The incentive fee hastwo parts. The first part, the income incentive fee, is calculated and payable quarterly in arrears based on our pre-incentive fee net investment income for the immediately preceding calendar quarter. For this purpose, pre-incentive fee net investment income means interest income, dividend income and any other income (including any other fees (other than fees for providing managerial assistance), such as commitment, origination, structuring, diligence and consulting fees and other fees that we receive from portfolio companies) accrued during the calendar quarter, minus our operating expenses for the quarter (including the base management fee, expenses payable under the Administration Agreement described below, and any interest expense and dividends paid on any issued and outstanding preferred stock, but excluding the incentive fee). Pre-incentive fee net investment income includes, in the case of investments with a deferred interest feature (such as original issue discount, debt instruments with payment-in-kind interest and zero coupon securities), accrued income that we have not yet received in cash. Pre-incentive fee net investment income does not include any realized capital gains, realized capital losses or unrealized capital gains or losses. Pre-incentive fee net investment income, expressed as a rate of return on the value of our net assets at the end of the immediately preceding calendar quarter, is compared to a “hurdle rate” of 1.75% per quarter (7.00% annualized).

The net investment income used to calculate this part of the incentive fee is also included in the amount of the gross assets used to calculate the 2.00% base management fee. We pay the Investment Adviser an income incentive fee with respect to our pre-incentive fee net investment income in each calendar quarter as follows:

•No incentive fee in any calendar quarter in which our pre-incentive fee net investment income does not exceed the hurdle rate;

•100.00% of our pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the hurdle rate but is less than 125.00% of the quarterly hurdle rate in any calendar quarter (8.75% annualized assuming a 7.00% annualized hurdle rate); and

•20.00% of the amount of our pre-incentive fee net investment income, if any, that exceeds 125.00% of the quarterly hurdle rate in any calendar quarter (8.75% annualized assuming a 7.00% annualized hurdle rate).

These calculations are appropriately prorated for any period of less than three months and adjusted for any share issuances or repurchases during the current quarter.

The second part of the incentive fee, the capital gains incentive fee, is determined and payable in arrears as of the end of each calendar year (or upon termination of the Investment Advisory Agreement, as of the termination date), and equals 20.00% of our realized capital gains for the calendar year, if any, computed net of all realized capital losses and unrealized capital depreciation at the end of such year. In determining the capital gains incentive fee payable to the Investment Adviser, we calculate the aggregate realized capital gains, aggregate realized capital losses and aggregate unrealized capital depreciation, as applicable, with respect to each investment that has been in our portfolio. For the purpose of this calculation, an “investment” is defined as the total of all rights and claims which may be asserted against a portfolio company arising from our participation in the debt, equity, and other financial instruments issued by that company. Aggregate realized capital gains, if any, equal the sum of the differences between the aggregate net sales price of each investment and the aggregate amortized cost basis of such investment when sold or otherwise disposed. Aggregate realized capital losses equal the sum of the amounts by which the aggregate net sales price of each investment is less than the aggregate amortized cost basis of such investment when sold or otherwise disposed. Aggregate unrealized capital depreciation equals the sum of the differences, if negative, between the aggregate valuation of each investment and the aggregate amortized cost basis of such investment as of the applicable calendar year-end. At the end of the applicable calendar year, the amount of capital gains that serves as the basis for our calculation of the capital gains incentive fee involves netting aggregate realized capital gains against aggregate realized capital losses on a since-inception basis and then reducing this amount by the aggregate unrealized capital depreciation. If this number is positive, then the capital gains incentive fee payable is equal to 20.00% of such amount, less the aggregate amount of any capital gains incentive fees paid since inception.

The total income incentive fee incurred was $40,772, $80,548, and $87,435 during the years ended June 30, 2025, 2024, and 2023, respectively. No capital gains incentive fee was incurred during the years ended June 30, 2025, 2024, and 2023.

Administration Agreement

We have also entered into an administration agreement (the “Administration Agreement”) with Prospect Administration under which Prospect Administration, among other things, provides (or arranges for the provision of) administrative services and facilities for us. For providing these services, we reimburse Prospect Administration for our allocable portion of overhead incurred by Prospect Administration in performing its obligations under the Administration Agreement, including rent and our allocable portion of the costs of our Chief Financial Officer and Chief Compliance Officer and her staff, including the internal legal staff. Under this agreement, Prospect Administration furnishes us with office facilities, equipment and clerical, bookkeeping and record keeping services at such facilities. Prospect Administration also performs, or oversees the performance of, our required administrative services, which include, among other things, being responsible for the financial records that we are required to maintain and preparing reports to our stockholders and reports filed with the SEC. In addition, Prospect Administration assists us in determining and publishing our net asset value, overseeing the preparation and filing of our tax returns and the printing and dissemination of reports to our stockholders, and generally oversees the payment of our expenses and the performance of administrative and professional services rendered to us by others. Under the Administration Agreement, Prospect Administration also provides on our behalf managerial assistance to certain portfolio companies (see Managerial Assistance to Portfolio Companies section below). The Administration Agreement may be terminated by either party without penalty upon 60 days’ written notice to the other party. Prospect Administration is a wholly-owned subsidiary of the Investment Adviser.

The Administration Agreement provides that, absent willful misfeasance, bad faith or negligence in the performance of its duties or by reason of the reckless disregard of its duties and obligations, Prospect Administration and its officers, managers, partners, agents, employees, controlling persons, members and any other person or entity affiliated with it are entitled to indemnification from us for any damages, liabilities, costs and expenses (including reasonable attorneys’ fees and amounts reasonably paid in settlement) arising from the rendering of Prospect Administration’s services under the Administration Agreement or otherwise as administrator for us. Our payments to Prospect Administration are reviewed quarterly by our Board of Directors.

The allocation of net overhead expense from Prospect Administration was $22,257, $25,781, and $20,578 for the years ended June 30, 2025, 2024, and 2023, respectively. Prospect Administration received estimated payments of $3,524, $4,435, and $2,664 directly from our portfolio companies and certain funds managed by the Investment Adviser for legal, tax, and other administrative services during the years ended June 30, 2025, 2024, and 2023, respectively. In addition, we were given a credit in the amount of $1,212 for legal expense incurred on behalf of our portfolio companies that were remitted to Prospect Administration during the year ended June 30, 2023. We were given a credit for these payments as a reduction of the administrative services cost payable by us to Prospect Administration. Had Prospect Administration not received these payments during theyears ended June 30, 2025, 2024, and 2023, Prospect Administration’s charges for its administrative services during the respective periods would have increased by this amount.

Managerial Assistance

As a BDC, we are obligated under the 1940 Act to make available to certain of our portfolio companies significant managerial assistance. “Making available significant managerial assistance” refers to any arrangement whereby we provide significant guidance and counsel concerning the management, operations, or business objectives and policies of a portfolio company. We are also deemed to be providing managerial assistance to all portfolio companies that we control, either by ourselves or in conjunction with others. The nature and extent of significant managerial assistance provided by us to controlled and non-controlled portfolio companies will vary according to the particular needs of each portfolio company. Examples of such activities include (i) advice on recruiting, hiring, management and termination of employees, officers and directors, succession planning and other human resource matters; (ii) advice on capital raising, capital budgeting, and capital expenditures; (iii) advice on advertising, marketing, and sales; (iv) advice on fulfillment, operations, and execution; (v) advice on managing relationships with unions and other personnel organizations, financing sources, vendors, customers, lessors, lessees, lawyers, accountants, regulators and other important counterparties; (vi) evaluating acquisition and divestiture opportunities, plant expansions and closings, and market expansions; (vii) participating in audit committee, nominating committee, board and management meetings; (viii) consulting with and advising board members and officers of portfolio companies (on overall strategy and other matters); and (ix) providing other organizational, operational, managerial and financial guidance.

Prospect Administration arranges for the provision of such managerial assistance arrangement on our behalf. When doing so, Prospect Administration utilizes personnel of our Investment Adviser.

Co-Investments

On January 13, 2020 (amended on August 2, 2022), we received an exemptive order from the SEC (the “Order”), which superseded a prior co-investment exemptive order granted on February 10, 2014, that gave us the ability to negotiate terms other than price and quantity of co-investment transactions with other funds managed by the Investment Adviser or certain affiliates, including Priority Income Fund, Inc. and Prospect Floating Rate and Alternative Income Fund, Inc., where co-investing would otherwise be prohibited under the 1940 Act, subject to the conditions included therein.

Under the terms of the relief permitting us to co-invest with other funds managed by our Investment Adviser or its affiliates, a “required majority” (as defined in Section 57(o) of the 1940 Act) of our independent directors must make certain conclusions in connection with a co-investment transaction, including that (1) the terms of the proposed transaction, including the consideration to be paid, are reasonable and fair to us and our stockholders and do not involve overreaching of us or our stockholders on the part of any person concerned and (2) the transaction is consistent with the interests of our stockholders and is consistent with our investment objective and strategies. In certain situations where a co-investment with one or more funds managed by the Investment Adviser or its affiliates is not covered by the Order, such as when there is an opportunity to invest in different securities of the same issuer, the personnel of the Investment Adviser or its affiliates will need to decide which fund will proceed with the investment. Such personnel will make these determinations based on policies and procedures, which are designed to reasonably ensure that investment opportunities are allocated fairly and equitably among affiliated funds over time and in a manner that is consistent with applicable laws, rules and regulations. Moreover, except in certain circumstances, when relying on the Order, we will be unable to invest in any issuer in which one or more funds managed by the Investment Adviser or its affiliates has previously invested.

We reimburse CLO investment valuation services fees initially incurred by Priority Income Fund, Inc. During the years ended June 30, 2025, 2024, and 2023, we recognized expenses related to valuation services of $89, $80, and $85, respectively. Additionally, we both incur and reimburse for expenses related to marketing, insurance, legal fees, offering costs and general and administrative expenses that are allocated between Prospect, Priority Income Fund, Inc. and Prospect Floating Rate & Alternative Income Fund Inc.
