GLADSTONE INVESTMENT CORPORATION\DE

(DOLLAR AMOUNTS IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA AND AS OTHERWISE INDICATED)

NOTE 1. ORGANIZATION

Gladstone Investment Corporation (“Gladstone Investment”) was incorporated under the General Corporation Law of the State of Delaware on February 18, 2005, and completed an initial public offering on June 22, 2005. The terms “the Company,” “we,” “our” and “us” all refer to Gladstone Investment and its consolidated subsidiaries. We are an externally managed, closed-end, non-diversified management investment company that has elected to be treated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (the “1940 Act”), and are applying the guidance of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, “Financial Services-Investment Companies” (“ASC 946”). In addition, we have elected to be treated for U.S. federal income tax purposes as a regulated investment company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”). We were established for the purpose of investing in debt and equity securities of established private businesses in the United States (“U.S.”). Debt investments primarily take the form of two types of loans: secured first lien loans and secured second lien loans. Equity investments primarily take the form of preferred or common equity (or warrants or options to acquire the foregoing), often in connection with buyouts and other recapitalizations. Our investment objectives are to: (i) achieve and grow current income by investing in debt securities of established businesses that we believe will provide stable earnings and cash flow to pay expenses, make principal and interest payments on our outstanding indebtedness and make distributions to stockholders that grow over time, and (ii) provide our stockholders with long-term capital appreciation in the value of our assets by investing in equity securities of established businesses, generally in combination with the aforementioned debt securities, that we believe can grow over time to permit us to sell our equity investments for capital gains. We intend that our investment portfolio over time will consist of approximately 75.0% in debt investments and 25.0% in equity investments, at cost. As of March 31, 2025, our investment portfolio was comprised of 73.3% in debt investments and 26.7% in equity investments, at cost.

Gladstone Business Investment, LLC (“Business Investment”), a wholly-owned subsidiary of ours, was established on August 11, 2006 for the sole purpose of holding certain investments pledged as collateral under our line of credit. The financial statements of Business Investment are consolidated with those of Gladstone Investment.

We are externally managed by Gladstone Management Corporation (the “Adviser”), an affiliate of ours and a U.S. Securities and Exchange Commission (“SEC”) registered investment adviser, pursuant to an investment advisory and management agreement (the “Advisory Agreement”). Administrative services are provided by Gladstone Administration, LLC (the “Administrator”), an affiliate of ours and the Adviser, pursuant to an administration agreement (the “Administration Agreement”). Refer to Note 4 —Related Party Transactions for more information regarding these arrangements.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The Consolidated Financial Statements and these accompanying notes are prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) and conform to the applicable requirements of Regulation S-X. Management believes it has made all necessary adjustments so that our accompanying Consolidated Financial Statements are presented fairly and that all such adjustments are of a normal recurring nature. Our accompanying Consolidated Financial Statements include our accounts and the accounts of our wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated.

Consolidation

In accordance with Article 6 of Regulation S-X, we do not consolidate portfolio company investments. Under the investment company rules and regulations pursuant to the American Institute of Certified Public Accountants Audit and Accounting Guide for Investment Companies, codified in ASC 946, we are precluded from consolidating any entity other than another investment company, except that ASC 946 provides for the consolidation of a controlled operating company that provides substantially all of its services to the investment company or its consolidated subsidiaries.

Use of Estimates

Preparing financial statements requires management to make estimates and assumptions that affect the amounts reported in our accompanying Consolidated Financial Statements and these Notes to Consolidated Financial Statements. Actual results may differ from those estimates.

Cash and Cash Equivalents

We consider all short-term, highly-liquid investments that are both readily convertible to cash and have a maturity of three months or less at the time of purchase to be cash equivalents. Cash and cash equivalents are carried at cost, which approximates fair value. We place our cash with financial institutions, and at times, cash held in checking accounts may exceed the Federal Deposit Insurance Corporation insured limit. We seek to mitigate this concentration of credit risk by depositing funds with major financial institutions. We held $1.8 million and $1.9 million of cash equivalents in Dreyfus Treasury Obligations Cash Management Fund as of March 31, 2025 and 2024, respectively. Investments in money market funds represent Level 1 investments within the GAAP fair value hierarchy.

Restricted Cash and Cash Equivalents

Restricted cash and cash equivalents are generally cash and cash equivalents held in escrow received as part of an investment exit. Restricted cash and cash equivalents are carried at cost, which approximates fair value.

Classification of Investments

In accordance with the provisions of the 1940 Act applicable to BDCs, we classify portfolio investments on our accompanying Consolidated Statements of Assets and Liabilities, Consolidated Statements of Operations, and Consolidated Schedules of Investments into the following categories:

•Non-Control/Non-Affiliate Investments— Non-Control/Non-Affiliate investments are those that are neither control nor affiliate investments and in which we typically own less than 5.0% of the issued and outstanding voting securities;

•Affiliate Investments — Affiliate investments are those that are not Control investments and in which we own, with the power to vote, between and inclusive of 5.0% and 25.0% of the issued and outstanding voting securities; and

•Control Investments— Control investments are those where we have the power to exercise a controlling influence over the management or policies of the portfolio company, which may include owning, with the power to vote, more than 25.0% of the issued and outstanding voting securities.

Investment Valuation Policy

Accounting Recognition

We record our investments at fair value in accordance with FASB ASC Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”) and the 1940 Act. Investment transactions are recorded on the trade date. Realized gains or losses are generally measured by the difference between the net proceeds from the repayment or sale and the cost basis of the investment, without regard to unrealized appreciation or depreciation previously recognized, and include investments charged off during the period, net of recoveries. Unrealized appreciation or depreciation primarily reflects the change in investment fair values, including the reversal of previously recorded unrealized appreciation or depreciation when gains or losses are realized.

Board Responsibility

Our board of directors (the “Board of Directors”) has approved investment valuation policies and procedures pursuant to Rule 2a-5 under the 1940 Act (the “Policy”) and designated the Adviser to serve as the Board of Directors’ valuation designee (“Valuation Designee”) under the 1940 Act.

In accordance with the 1940 Act, our Board of Directors has the ultimate responsibility for reviewing the good faith fair value determination of our investments for which market quotations are not readily available based on our Policy and for overseeing the Valuation Designee. Such review and oversight includes receiving written fair value determinations and supporting materials provided by the Valuation Designee, in coordination with the Administrator and with the oversight by the Company's chief valuation officer (collectively, the “Valuation Team”). The Valuation Committee of our Board of Directors (comprised entirely of independent directors) meets to review the valuation determinations and supporting materials, discusses the information provided by the Valuation Team, determines whether the Valuation Team has followed the Policy, and reviews other facts and circumstances, including current valuation risks, conflicts of interest, material valuation matters, appropriateness of valuation methodologies, back-testing results, price challenges/overrides, and ongoing monitoring and oversight of pricing services. After the Valuation Committee concludes its meeting, it and the chief valuation officer, representing the Valuation Designee, present the Valuation Committee’s findings on the Valuation Designee's determinations to the entire Board of Directors so that the full Board of Directors may review the Valuation Designee's determined fair values of such investments in accordance with the Policy.

There is no single standard for determining fair value (especially for privately-held businesses), as fair value depends upon the specific facts and circumstances of each individual investment. In determining the fair value of our investments, the Valuation Team, led by the chief valuation officer, uses the Policy, and each quarter the Valuation Committee and Board of Directors review the Policy to determine if changes thereto are advisable and whether the Valuation Team has applied the Policy consistently.

Use of Third-Party Valuation Firms

The Valuation Team engages third party valuation firms to provide independent assessments of fair value of certain of our investments.

A third-party valuation firm generally provides estimates of fair value on our debt investments. The Valuation Team generally assigns the third-party valuation firm’s estimates of fair value to our debt investments where we do not have the ability to effectuate a sale of the applicable portfolio company. The Valuation Team corroborates the third-party valuation firm’s estimates of fair value using one or more of the valuation techniques discussed below. The Valuation Team’s estimate of value on a specific debt investment may significantly differ from the third-party valuation firm’s. When this occurs, our Valuation Committee and Board of Directors review whether the Valuation Team has followed the Policy and the Valuation Committee reviews whether the Valuation Designee’s determined fair value is reasonable in light of the Policy and other relevant facts and circumstances.

We may engage other independent valuation firms to provide earnings multiple ranges, as well as other information, and evaluate such information for incorporation into the total enterprise value (“TEV”) of certain of our investments. Generally, at least once per year, we engage an independent valuation firm to value or review the valuation of each of our significant equity investments, which includes providing the information noted above. The Valuation Team evaluates such information for incorporation into our TEV, including review of all inputs provided by the independent valuation firm. The Valuation Team then presents a determination to our Valuation Committee as to the fair value. Our Valuation Committee reviews the determined fair value and whether it is reasonable in light of the Policy and other relevant facts and circumstances.

Valuation Techniques

In accordance with ASC 820, the Valuation Team uses the following techniques when valuing our investment portfolio:

•Total Enterprise Value — In determining the fair value using a TEV, the Valuation Team first calculates the TEV of the portfolio company by incorporating some or all of the following factors: the portfolio company’s ability to make payments and other specific portfolio company attributes; the earnings of the portfolio company (the trailing or projected twelve month revenue or earnings before interest, taxes, depreciation and amortization (“EBITDA”)); EBITDA multiples obtained from our indexing methodology whereby the original transaction EBITDA multiple at the time of our closing is indexed to a general subset of comparable disclosed transactions and EBITDA multiples from recent sales to third parties of similar securities in similar industries; a comparison to publicly traded securities in similar industries; and other pertinent factors. The Valuation Team generally reviews industry statistics and may use outside experts when gathering this information. Once the TEV is determined for a portfolio company, the Valuation Team generally allocates the TEV to the portfolio company’s securities based on the facts and circumstances of the securities, which typically results in the allocation of fair value to securities based on the order of their relative priority in the capital structure. Generally, the Valuation Team uses TEV to value our equity investments and, in the circumstances where we have the ability to effectuate a sale of a portfolio company, our debt investments. When there is equity value or sufficient TEV to cover the principal balance of our debt securities, the fair value of our senior secured debt generally equals or approximates cost.

TEV is primarily calculated using EBITDA and EBITDA multiples; however, TEV may also be calculated using revenue and revenue multiples or a discounted cash flow (“DCF”) analysis whereby future expected cash flows of the portfolio company are discounted to determine a net present value using estimated risk-adjusted discount rates, which incorporate adjustments for nonperformance and liquidity risks.

•Yield Analysis — The Valuation Team generally determines the fair value of our debt investments for which we do not have the ability to effectuate a sale of the applicable portfolio company using the yield analysis, which includes a DCF calculation and assumptions that the Valuation Team believes market participants would use, including: estimated remaining life, current market yield, current leverage, and interest rate spreads. This technique develops a modified discount rate that incorporates risk premiums including, among other things, increased probability of default, increased loss upon default, and increased liquidity risk. Generally, the Valuation Team uses the yield analysis to corroborate both estimates of value provided by a third-party valuation firm and market quotes.

•Market Quotes — For our investments for which a limited market exists, we generally base fair value on readily available and reliable market quotations, which are corroborated by the Valuation Team (generally by using the yield analysis described above). In addition, the Valuation Team assesses trading activity for similar investments and evaluates variances in quotations and other market insights to determine if any available quoted prices are reliable. Typically, the Valuation Team uses the lower indicative bid price in the bid-to-ask price range obtained from the respective originating syndication agent’s trading desk on or near the valuation date. The Valuation Team may take further steps to consider additional information to validate that price in accordance with the Policy. For securities that are publicly traded, we generally base fair value on the closing market price of the securities we hold as of the reporting date. For restricted securities that are publicly traded, we generally base fair value on the closing market price of the securities we hold as of the reporting date less a discount for the restriction, which includes consideration of the nature and term to expiration of the restriction and the lack of marketability of the security.

•Investments in Funds — For equity investments in other funds for which we cannot effectuate a sale of the fund, the Valuation Team generally determines the fair value of our invested capital at the net asset value (“NAV”) provided by the fund. Any invested capital that is not yet reflected in the NAV provided by the fund is valued at par value. The Valuation Team may also determine fair value of our investments in other investment funds based on the capital accounts of the underlying entity.

In addition to the valuation techniques listed above, the Valuation Team may also consider other factors when determining the fair value of our investments, including: the nature and realizable value of the collateral, including external parties’ guaranties, any relevant offers or letters of intent to acquire the portfolio company, timing of expected loan repayments, and the markets in which the portfolio company operates.

Fair value measurements of our investments may involve subjective judgments and estimates and, due to the uncertainty inherent in valuing these securities, the determinations of fair value may fluctuate from period to period and may differ materially from the values that could be obtained if a ready market for these securities existed. Our NAV could be materially affected if the determinations regarding the fair value of our investments are materially different from the values that we ultimately realize upon our disposal of such securities. Additionally, changes in the market environment and other events that may occur over the life of the investment may cause the gains or losses ultimately realized on these investments to be different than the valuations currently assigned. 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, we could realize significantly less than the value at which it is recorded.

Refer to Note 3—Investments for additional information regarding fair value measurements and our application of ASC 820.

Realized Gain or Loss and Unrealized Appreciation or Depreciation of Portfolio Investments

Gains or losses on the sale of investments are calculated by using the specific identification method. A realized gain or loss is recognized on the trade date, typically when an investment is disposed of, and is computed as the difference between the cost basis of the investment on the disposition date and the net proceeds received from such disposition. Unrealized appreciation or depreciation reflects the difference between the fair value of the investment and the cost basis of such investment. We determine the fair value of each individual investment each reporting period and record changes in fair value as unrealized appreciation or depreciation in our accompanying Consolidated Statement of Operations.

Revenue Recognition

Interest Income Recognition

Interest income, adjusted for amortization of premiums, amendment fees, and acquisition costs and the accretion of discounts, is recorded on the accrual basis to the extent that such amounts are expected to be collected. Generally, when a loan becomes 90 days or more past due, or if our qualitative assessment indicates that the debtor is unable to service its debt or other obligations, we will place the loan on non-accrual status and cease recognizing interest income on that loan until the borrower has demonstrated the ability and intent to pay contractual amounts due. However, we remain contractually entitled to this interest. Interest payments received on non-accrual loans may be recognized as income or applied to the cost basis, depending upon management’s judgment. Generally, non-accrual loans are restored to accrual status when past-due principal and interest are paid and, in management’s judgment, are likely to remain current, or, due to a restructuring, the interest income is deemed to be collectible. As of March 31, 2025, our loans to B+T Group Acquisition, Inc., Diligent Delivery Systems, Edge Adhesives Holdings, Inc. ("Edge"), and J.R. Hobbs Co. – Atlanta, LLC (“J.R. Hobbs”) were on non-accrual status, with an aggregate debt cost basis of $90.2 million, or 13.1% of the cost basis of all debt investments in our portfolio, and an aggregate fair value of $50.9 million, or 8.2% of the fair value of all debt investments in our portfolio. As of March 31, 2024, our loans to Edge and J.R. Hobbs were on non-accrual status, with an aggregate debt cost basis of $59.1 million, or 9.0% of the cost basis of all debt investments in our portfolio, and an aggregate fair value of $29.7 million, or 4.8% of the fair value of all debt investments in our portfolio.

Paid-in-kind (“PIK”) interest, computed at the contractual rate specified in the loan agreement, is added to the principal balance of the loan and recorded as interest income. Thus, the actual collection of PIK income may be deferred until the time of debt principal repayment. As of March 31, 2025 and 2024, we did not have any loans with a PIK interest component.

Success Fee Income Recognition

We record success fees as income when earned, which often occurs upon receipt of cash. Success fees are generally contractually due upon a change of control in a portfolio company, typically resulting from an exit or sale, and are non-recurring.

Dividend Income Recognition

We accrue dividend income on preferred and common equity securities to the extent that such amounts are expected to be collected and if we have the option to collect such amounts in cash or other consideration.

Deferred Financing and Offering Costs

Deferred financing and offering costs consist of costs incurred to obtain financing, including lender fees, underwriting discounts and commissions, and legal fees. Certain costs associated with our revolving line of credit are deferred and amortized using the straight-line method, which approximates the effective interest method, over the term of the revolving line of credit. Costs associated with the issuance of our notes payable and mandatorily redeemable preferred stock are presented as discounts to the liquidation value of the notes payable and mandatorily redeemable preferred stock and are amortized using the straight-line method, which approximates the effective interest method, over the term of the notes payable and respective series of preferred stock. Refer to Note 5—Borrowingsfor further discussion.

Related Party Fees

We are party to the Advisory Agreement with the Adviser, which is indirectly owned and controlled by our chairman and chief executive officer. In accordance with the Advisory Agreement, we pay the Adviser fees as compensation for its services, consisting of a base management fee and an incentive fee. Additionally, we pay the Adviser a loan servicing fee as compensation for its services as servicer under the terms of the Fifth Amended and Restated Credit Agreement dated April 30, 2013, as amended from time to time (the "Credit Facility").

We are also party to the Administration Agreement with the Administrator, which is indirectly owned and controlled by our chairman and chief executive officer, whereby we pay separately for administrative services.

Refer to Note 4—Related Party Transactionsfor additional information regarding these related party fees and agreements.

Federal Income Taxes

We intend to continue to maintain our qualification as a RIC under subchapter M of the Code for federal income tax purposes. As a RIC, we generally are not subject to federal income tax on the portion of our taxable income and gains distributed to our stockholders. To maintain our qualification as a RIC, we must maintain our status as a BDC and meet certain source-of-income and asset diversification requirements. In addition, to qualify to be taxed as a RIC, we must generally distribute to stockholders, for each taxable year, at least 90% of our taxable ordinary income plus the excess of our net short-term capital gains over net long-term capital losses (“Investment Company Taxable Income”). Our policy generally is to make distributions to our stockholders in an amount up to 100% of our Investment Company Taxable Income. We intend to continue to make sufficient distributions to qualify as a RIC and to generally limit taxable income, although we may retain some or all of our net long-term capital gains and pay income taxes on such gains. Refer to Note 9—Federal and State Income Taxes for additional information regarding our RIC requirements.

FASB ASC 740, Income Taxes (“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 authorities. Tax positions not deemed to satisfy the “more-likely-than-not” threshold would be recorded as a tax benefit or expense in the current fiscal year. We have evaluated the implications of ASC 740 for all open tax years and in all major tax jurisdictions and determined that there is no material impact on our accompanying Consolidated Financial Statements. Our federal income tax returns for fiscal years 2024, 2023 and 2022 remain subject to examination by the Internal Revenue Service (“IRS”). We are not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized benefits will change materially in the next twelve months.

Distributions to stockholders are recorded on the ex-dividend date. We are required to distribute at least 90% of our Investment Company Taxable Income for each taxable year as a distribution to our stockholders to maintain our ability to be taxed as a RIC under Subchapter M of the Code. It is our policy to generally pay out as a distribution up to 100% of those amounts. The amount to be paid is determined by our Board of Directors and is based upon management’s estimate of Investment Company Taxable Income, net long-term capital gains, as well as amounts to be distributed in accordance with Section 855(a) of the Code. Based on that estimate, our Board of Directors declares monthly distributions, and supplemental distributions, as applicable, each quarter. At fiscal year-end, we may elect to treat a portion of the first distributions paid after year-end as having been paid in the prior year in accordance with Section 855(a) of the Code. We may retain some or all of our net long-term capital gains, if any, and designate them as deemed distributions, or distribute these capital gains to stockholders in cash. If we elect to retain net long-term capital gains and deem them distributed, each U.S. common stockholder will be treated as if they received a distribution of their pro-rata share of the retained net long-term capital gain and the U.S. federal income tax paid. As a result, each common stockholder will (i) be required to report their pro-rata share of the retained gain on their tax return as long-term capital gain, (ii) receive a refundable tax credit for their pro-rata share of federal income tax paid by us on the retained gain, and (iii) increase the tax basis of their shares of common stock by an amount equal to the deemed distribution less the tax credit. Refer to Note 8 —Distributions to Common Stockholders for further information.

Our common stockholders who hold their shares through our transfer agent, Computershare, Inc. (“Computershare”), have the option to participate in a dividend reinvestment plan offered by Computershare, as the plan agent. This is an “opt in” dividend reinvestment plan, meaning that common stockholders may elect to have their cash distributions automatically reinvested in additional shares of our common stock. Common stockholders who do not so elect will receive their distributions in cash. Any distributions reinvested under the plan will be taxable to a common stockholder to the same extent, and with the same character, as if the common stockholder had received the distribution in cash. The common stockholder will have an adjusted basis in the additional common shares purchased through the plan equal to the dollar amount that would have been received if the U.S. stockholder had received the dividend or distribution in cash. The additional common shares will have a new holding period commencing on the day following the date on which the shares are credited to the common stockholder’s account. Computershare purchases shares in the open market in connection with the obligations under the plan.

Segment Reporting

In November 2023, the FASB issued Accounting Standards Update 2023-07, “Segment Reporting - Improvements to Reportable Segment Disclosures” ("ASU 2023-07") to improve reportable segments disclosure requirements. The ASU requires existing annual segment disclosures to also be disclosed on an interim basis and also requires additional disclosures around significant segment expenses and disclosures to identify the title and position of the chief operating decision maker (“CODM”). The standard is effective for fiscal years beginning after December 15, 2023, and interim periods thereafter. We adopted ASU 2023-07 as of March 31, 2025.

Our current business strategy includesone reporting segment which derives investment income from our portfolio companies. Our CODM is our Chief Executive Officer. The CODM assesses performance based on net investment income, net realized and unrealized gains (losses) and net increase (decrease) in net assets resulting from operations, which are reported on the Consolidated Statement of Operations. The expense categories included on the Consolidated Statement of Operations reflect our significant expense categories and are provided to the CODM on a regular basis.

Recent Accounting Pronouncements

In June 2022, the FASB issued Accounting Standards Update 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions” (“ASU 2022-03”), which clarifies the measurement and presentation of fair value for equity securities subject to contractual restrictions that prohibit the sale of the equity security. ASU 2022-03 is effective for annual reporting periods beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted. Our early adoption of ASU 2022-03 did not have a material impact on our financial position, results of operations or cash flows.

NOTE 3. INVESTMENTS

Fair Value

In accordance with ASC 820, the fair value of our investments is determined to be the price that would be received for an investment in a current sale, which assumes an orderly transaction between willing market participants on the measurement date. This fair value definition focuses on exit price in the principal, or most advantageous, market and prioritizes, within a measurement of fair value, the use of market-based inputs over entity-specific inputs. ASC 820 also establishes the following three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of a financial instrument as of the measurement date.

•Level 1 — inputs to the valuation methodology are quoted prices (unadjusted) for identical financial instruments in active markets;

•Level 2 — inputs to the valuation methodology include quoted prices for similar financial instruments in active or inactive markets, and inputs that are observable for the financial instrument, either directly or indirectly, for substantially the full term of the financial instrument. Level 2 inputs are those in markets for which there are few transactions, the prices are not current, little public information exists, or instances where prices vary substantially over time or among brokered market makers; and

•Level 3 — inputs to the valuation methodology are unobservable and significant to the fair value measurement. Unobservable inputs are those inputs that reflect assumptions that market participants would use when pricing the financial instrument and can include the Valuation Team’s assumptions based upon the best available information.

When a determination is made to classify our investments within Level 3 of the valuation hierarchy, such determination is based upon the significance of the unobservable factors to the overall fair value measurement. However, Level 3 financial instruments typically include, in addition to the unobservable, or Level 3, inputs, observable inputs (or components that are actively quoted and can be validated to external sources). The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement.

As of March 31, 2025, all of our investments were valued using Level 3 inputs within the ASC 820 fair value hierarchy, except for our investment in Gladstone Alternative Income Fund ("Gladstone Alternative"), which was valued using NAV as a practical expedient.

As of March 31, 2024, all of our investments were valued using Level 3 inputs within the ASC 820 fair value hierarchy, except for our investment in Funko Acquisition Holdings, LLC (“Funko”), which was valued using Level 2 inputs.

We transfer investments in and out of Level 1, 2 and 3 of the valuation hierarchy as of the beginning balance sheet date, based on changes in the use of observable and unobservable inputs utilized to perform the valuation for the period. There were no transfers in or out of Level 1, 2 and 3 during the years ended March 31, 2025 and 2024, respectively.

As of March 31, 2025 and 2024, our investments, by security type, at fair value were categorized as follows within the ASC 820 fair value hierarchy:

(A)Includes our investment in Gladstone Alternative as of March 31, 2025. Investments that are measured at fair value using NAV as a practical expedient have not been categorized in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented elsewhere in this Annual Report.

(B)Fair value was determined based on the closing market price of shares of Funko, Inc. (our units in Funko can be converted into common shares of Funko, Inc.) at the reporting date less a discount for lack of marketability, as our investment was subject to certain restrictions.

The following table presents our investments, valued using Level 3 inputs within the ASC 820 fair value hierarchy, and carried at fair value as of March 31, 2025 and 2024, by caption on our accompanying Consolidated Statements of Assets and Liabilities, and by security type:

(A)Excludes our investment in Funko with a fair value of $18 thousand as of March 31, 2024, which was valued using Level 2 inputs.

(B)Excludes our investment in Gladstone Alternative as of March 31, 2025 with a fair value of $5.0 million, which was valued using NAV as a practical expedient.

In accordance with ASC 820, the following table provides quantitative information about our investments valued using Level 3 fair value measurements as of March 31, 2025 and 2024. The table below is not intended to be all-inclusive, but rather provides information on the significant Level 3 inputs as they relate to our fair value measurements. The weighted-average calculations in the table below are based on the principal balances for all debt-related calculations and on the cost basis for all equity-related calculations for the particular input.

(A)Fair value as of March 31, 2025 excludes our investment in Gladstone Alternative with a fair value of $5.0 million, which was valued using NAV as a practical expedient.

(B)Fair value as of March 31, 2024 excludes our investment in Funko with a fair value of $18 thousand, which was valued using Level 2 inputs.

Fair value measurements can be sensitive to changes in one or more of the valuation inputs. Changes in discount rates, EBITDA, or EBITDA multiples (or revenue or revenue multiples), each in isolation, may change the fair value of certain of our investments. Generally, an increase/(decrease) in market yields, discount rates or a (decrease)/increase in EBITDA or EBITDA multiples (or revenue or revenue multiples) may result in a (decrease)/increase in the fair value of certain of our investments.

Changes in Level 3 Fair Value Measurements of Investments

The following tables provide our portfolio’s changes in fair value, broken out by security type, during the years ended March 31, 2025 and 2024 for all investments for which the Adviser determines fair value using unobservable (Level 3) inputs.

Fair Value Measurements Using Significant Unobservable Inputs (Level 3)

(A)Included in net realized gain (loss) on investments on our accompanying Consolidated Statements of Operations for the respective years ended March 31, 2025 and 2024.

(B)Included in net unrealized (depreciation) appreciation of investments on our accompanying Consolidated Statements of Operations for the respective years ended March 31, 2025 and 2024.

(C)Includes increases in the cost basis of investments resulting from new portfolio investments, the amortization of discounts, and other non-cash disbursements to portfolio companies, as well as decreases in the cost basis of investments resulting from principal repayments or sales, the amortization of premiums and acquisition costs, and other cost-basis adjustments.

(D)2024: Includes $0.3 million of proceeds from the recapitalization of Old World Christmas, Inc.

(E)2025: Transfers represent secured second lien debt of PSI Molded Plastics, Inc. ("PSI Molded") with a total cost basis of $16.4 million and $9.8 million, which was converted to preferred equity in January 2025.

2024: Transfers represent preferred equity of SFEG Holdings, Inc. ("SFEG") with a total cost basis and fair value of $4.8 million and $8.6 million, respectively, which was converted to common equity in October 2023.

Investment Activity

During the fiscal year ended March 31, 2025, the following significant transactions occurred:

•In May 2024, our remaining shares in Funko were sold representing an exit of our investment in Funko, and resulting in a return of our equity cost basis of $21 thousand and a realized gain of $2 thousand.

•In July 2024, we invested an additional $18.5 million through secured first lien debt in Nocturne Luxury Villas, Inc. ("Nocturne") to fund an add-on acquisition.

•In September 2024, we exited our investment in Nth Degree Investment Group, LLC, which resulted in success fee income of $0.1 million, a realized gain on our preferred equity of $42.3 million and the repayment of our debt investment of $25.0 million at par.

NOTE 4. RELATED PARTY TRANSACTIONS

Transactions with the Adviser

We pay the Adviser certain fees as compensation for its services under the Advisory Agreement, consisting of a base management fee and an incentive fee and a loan servicing fee for the Adviser’s role as servicer pursuant to our Credit Facility, all as described below. Our Board of Directors, including a majority of the directors who are not parties to the Advisory Agreement or interested persons of either party, approved the Advisory Agreement. On January 24, 2025, the Company entered into the Advisory Agreement, which was approved by the Company’s stockholders at a stockholders’ meeting on January 4, 2024, as a result of a change of control of the Adviser pursuant to the previously disclosed voting trust agreement. There are no changes to the terms, including the fee structure and services to be provided, of the prior Advisory Agreement, other than the date and term of the Advisory Agreement.

One of our executive officers, David Gladstone (our chairman and chief executive officer) serves as a director and executive officer of the Adviser, which, as of March 31, 2025, is 100% indirectly owned by Mr. Gladstone. David Dullum (our president) is also the executive vice president of private equity (buyouts) of the Adviser. Michael LiCalsi, our general counsel and secretary (who also serves as the Administrator’s president, general counsel and secretary), is also the executive vice president of administration, general counsel, and secretary of our Adviser.

The following table summarizes the base management fees, loan servicing fees, incentive fees, and associated non-contractual, unconditional, and irrevocable credits reflected in our accompanying Consolidated Statements of Operations:

(A)Average total assets subject to the base management fee is defined in the Advisory Agreement as total assets, including investments made with proceeds of borrowings, less any uninvested cash or cash equivalents resulting from borrowings, valued at the end of the applicable quarters within the respective periods and adjusted appropriately for any share issuances or repurchases during the periods.

(B)Excludes our investment in Gladstone Alternative valued at the end of the applicable quarters within the respective periods.

(C)Reflected as a line item on our accompanying Consolidated Statements of Operations.

(D)The capital gains-based incentive fees are recorded in accordance with GAAP and do not necessarily reflect amounts contractually due under the terms of the Advisory Agreement.

Base Management Fee

The base management fee is payable quarterly to the Adviser pursuant to our Advisory Agreement and is assessed at an annual rate of 2.0%, computed on the basis of the value of our average gross assets at the end of the two most recently completed quarters (inclusive of the current quarter), which are total assets, including investments made with proceeds of borrowings, less any uninvested cash or cash equivalents resulting from borrowings, valued at the end of the applicable quarters within the respective period and adjusted appropriately for any share issuances or repurchases during the period.

Additionally, pursuant to the requirements of the 1940 Act, the Adviser makes available significant managerial assistance to our portfolio companies. The Adviser may also provide other services to our portfolio companies under certain agreements and may receive fees for services other than managerial assistance. Such services may include: (i) assistance obtaining, sourcing or structuring credit facilities, long term loans or additional equity from unaffiliated third parties; (ii) negotiating important contractual financial relationships; (iii) consulting services regarding restructuring of the portfolio company and financial modeling as it relates to raising additional debt and equity capital from unaffiliated third parties; and (iv) taking a primary role in interviewing, vetting, and negotiating employment contracts with candidates in connection with adding and retaining key portfolio company management team members. The Adviser non-contractually, unconditionally, and irrevocably credits 100% of any fees received for such services against the base management fee that we would otherwise be required to pay to the Adviser; however, pursuant to the terms of the Advisory Agreement, a small percentage of certain of such fees, was retained by the Adviser in the form of reimbursement, at cost, for tasks completed by personnel of the Adviser, primarily related to the valuation of portfolio companies. For the years ended March 31, 2025, 2024, and 2023, these credits totaled $0.4 million, $0.3 million, and $0.2 million, respectively.

Loan Servicing Fee

The Adviser also services the loans held by our wholly-owned subsidiary, Business Investment (the borrower under the Credit Facility), in return for which the Adviser receives a 2.0% annual fee based on the monthly aggregate outstanding balance of loans pledged under our Credit Facility. Since Business Investment is a consolidated subsidiary of ours, coupled with the fact that the total base management fee paid to the Adviser pursuant to the Advisory Agreement cannot exceed 2.0% of total assets (less any uninvested cash or cash equivalents resulting from borrowings) during any given calendar year, we treat payment of the loan servicing fee pursuant to the Credit Facility as a pre-payment of the base management fee under the Advisory Agreement. Accordingly, these loan servicing fees are 100% non-contractually, unconditionally, and irrevocably credited back to us by the Adviser.

Incentive Fee

The incentive fee payable to the Adviser under our Advisory Agreement consists of two parts: an income-based incentive fee and a capital gains-based incentive fee.

The income-based incentive fee rewards the Adviser if our quarterly net investment income (before giving effect to any incentive fee) exceeds 1.75% of our net assets, which we define as total assets less indebtedness and before taking into account any incentive fees payable or contractually due but not payable during the period, at the end of the immediately preceding calendar quarter, adjusted appropriately for any share issuances or repurchases during the period (the “Hurdle Rate”). The income-based incentive fee with respect to our pre-incentive fee net investment income is payable quarterly to the Adviser and is computed as follows:

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

•100.0% 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 2.1875% of our net assets, adjusted appropriately for any share issuances or repurchases during the period, in any calendar quarter; and

•20.0% of the amount of our pre-incentive fee net investment income, if any, that exceeds 2.1875% of our net assets, adjusted appropriately for any share issuances or repurchases during the period, in any calendar quarter.

The second part of the incentive fee is a capital gains-based incentive fee that is determined and payable in arrears as of the end of each fiscal year (or upon termination of the Advisory Agreement, as of the termination date), and equals 20.0% of our realized capital gains, less any realized capital losses and unrealized depreciation, calculated as of the end of the preceding calendar year. The capital gains-based incentive fee payable to the Adviser is calculated based on (i) cumulative aggregate realized capital gains since our inception, less (ii) cumulative aggregate realized capital losses since our inception, less (iii) the entire portfolio’s aggregate unrealized capital depreciation, if any, as of the date of the calculation. If this number is positive at the applicable calculation date, then the capital gains-based incentive fee for such year equals 20.0% of such amount, less the aggregate amount of any capital gains-based incentive fees paid in respect of our portfolio in all prior years. For calculation purposes, cumulative aggregate realized capital gains, if any, equals the sum of the excess between the net sales price of each investment, when sold, and the original cost of such investment since our inception. Cumulative aggregate realized capital losses equals the sum of the deficit between the net sales price of each investment, when sold, and the original cost of such investment since our inception. The entire portfolio’s aggregate unrealized capital depreciation, if any, equals the sum of the deficit between the fair value of each investment security as of the applicable calculation date and the original cost of such investment security. For the years ended March 31, 2025 and 2024, capital gains-based incentive fees of $4.9 million and $1.1 million, respectively, were contractually due and paid to the Adviser. For the year ended March 31, 2023, no capital gains-based incentive fees were contractually due and paid to the Adviser.

In accordance with GAAP, accrual of the capital gains-based incentive fee is determined as if our investments had been liquidated at their fair values as of the end of the reporting period. Therefore, GAAP requires that the capital gains-based incentive fee accrual consider the aggregate unrealized capital appreciation in the calculation, as a capital gains-based incentive fee would be payable if such unrealized capital appreciation were realized. There can be no assurance that any such unrealized capital appreciation will be realized in the future. Accordingly, a GAAP accrual is calculated at the end of the reporting period based on (i) cumulative aggregate realized capital gains since our inception, plus (ii) the entire portfolio’s aggregate unrealized capital appreciation, if any, less (iii) cumulative aggregate realized capital losses since our inception, less (iv) the entire portfolio’s aggregate unrealized capital depreciation, if any. If such amount is positive at the end of a reporting period, a capital gains-based incentive fee equal to 20.0% of such amount, less the aggregate amount of capital gains-based incentive fees accrued in all prior years, is recorded, regardless of whether such amount is contractually due under the terms of the Advisory Agreement. If such amount is negative, then there is no accrual for such period and prior period accruals are reversed, as appropriate. During the years ended March 31, 2025, 2024 and 2023, we recorded/(reversed) capital gains-based incentive fees of $7.4 million, $12.7 million and $(0.3) million, respectively.

Transactions with the Administrator

We reimburse the Administrator pursuant to the Administration Agreement for our allocable portion of the Administrator’s expenses incurred while performing services to us, which are primarily rent and salaries and benefits expenses of the Administrator’s employees, including, our chief financial officer and treasurer, chief valuation officer, chief compliance officer, and general counsel and secretary, and their respective staffs. One of our executive officers, David Gladstone (our chairman and chief executive officer) serves as a member of the board of managers and executive officer of the Administrator, which is 100% indirectly owned and controlled by Mr. Gladstone. Another of our officers, Mr. LiCalsi (our general counsel and secretary), serves as the Administrator’s president as well as the executive vice president of administration, general counsel, and secretary for the Adviser.

Our allocable portion of the Administrator’s expenses is generally derived by multiplying the Administrator’s total expenses by the approximate percentage of time during the current quarter the Administrator’s employees performed services for us in relation to their time spent performing services for all companies serviced by the Administrator. On July 9, 2024, our Board of Directors, including a majority of the directors who are not parties to the Administration Agreement or interested persons of either party, approved the annual renewal of the Administration Agreement through August 31, 2025. For the years ended March 31, 2025, 2024 and 2023, administration fees were $1.9 million, $1.8 million and $1.8 million, respectively.

Transactions with Gladstone Securities, LLC

Gladstone Securities, LLC (“Gladstone Securities”) is a privately held broker dealer registered with the Financial Industry Regulatory Authority and insured by the Securities Investor Protection Corporation. Gladstone Securities is an affiliate of ours, as its parent company is 100% indirectly owned and controlled by David Gladstone, our chairman and chief executive officer. Mr. Gladstone also serves on the board of managers of Gladstone Securities.

From time to time, Gladstone Securities provides services, such as investment banking and due diligence services, to certain of our portfolio companies, for which it receives a fee. Any such fees paid by portfolio companies to Gladstone Securities do not impact the fees we pay to the Adviser or the non-contractual, unconditional, and irrevocable credits against the base management fee. During the years ended March 31, 2025, 2024, and 2023, the fees received by Gladstone Securities from portfolio companies totaled $2.0 million, $0.3 million, and $1.6 million, respectively.

Investment in Affiliated Fund

In December 2024, we invested in Gladstone Alternative, one of our affiliated funds, that is a registered, non-diversified, closed-end management investment company that operates as an interval fund. The fair value of the investment in Gladstone Alternative will be excluded from the average total assets subject to base management fee for the purposes of calculating the base management fee we pay to the Adviser.

Related Party Fees Due

Amounts due to related parties on our accompanying Consolidated Statements of Assets and Liabilities were as follows:

(A)Includes a capital gains-based incentive fee of $39.3 million and $36.7 million as of March 31, 2025 and 2024, respectively, recorded in accordance with GAAP requirements and which was not contractually due under the terms of the Advisory Agreement.

NOTE 5. BORROWINGS

Revolving Line of Credit

As of March 31, 2025, our Credit Facility had a total commitment amount of$270.0 million with an “accordion” feature that permits us to increase the size of the facility to $300.0 million. The Credit Facility has a revolving period end date of October 30, 2026 and a final maturity date of October 30, 2028 (at which time all principal and interest will be due and payable if the Credit Facility is not extended by the revolving period end date).

Advances under the Credit Facility generally bear interest at 30-day Term SOFR, subject to a floor of 0.35%, with a SOFR credit spread adjustment of 10 basis points, plus a margin of 3.15% per annum until October 30, 2026, with the margin then increasing to 3.40% for the period from October 30, 2026 to October 30, 2027, and increasing further to 3.65% thereafter. The Credit Facility has an unused commitment fee on the daily unused commitment amount of 0.50% per annum if the daily unused commitment amount is less than or equal to 50% of the total commitment amount,0.75% per annum if the daily unused commitment amount is greater than 50% but less than or equal to 65% of the total commitment amount, and 1.00% per annum if the daily unused commitment amount is greater than 65% of the total commitment amount.

The following tables summarize noteworthy information related to our Credit Facility:

(A)Availability is subject to various constraints, characteristics, and applicable advance rates based on collateral quality under our Credit Facility, which equated to an adjusted availability of$270.0 million and$133.0 million as of March 31, 2025 and 2024, respectively.

(B)Excludes the impact of deferred financing costs and includes unused commitment fees.

Interest is payable monthly during the term of our Credit Facility. Available borrowings are subject to various constraints and applicable advance rates, which are generally based on the size, characteristics, and quality of the collateral pledged by Business Investment. Our Credit Facility also requires that any interest and principal payments on pledged loans be remitted directly by the borrower into a lockbox account with KeyBank. KeyBank is also the trustee of the account and generally remits the collected funds to us once a month. Amounts collected in the lockbox account with KeyBank are presented as Due from administrative agent on the accompanying Consolidated Statements of Assets and Liabilities.

Among other things, our Credit Facility contains a performance guaranty that requires us to maintain (i) a minimum net worth of the greater of $210.0 million or $210.0 million plus 50% of all equity and subordinated debt raised, minus 50% of any equity or subordinated debt redeemed or retired after November 16, 2016, which equated to $412.9 million as of March 31, 2025; (ii) asset coverage with respect to senior securities representing indebtedness of at least 150% (or such percentage as may be set forth in Section 18 of the 1940 Act, as modified by Section 61 of the 1940 Act); and (iii) our status as a BDC under the 1940 Act and as a RIC under the Code. As of March 31, 2025, and as defined in the performance guaranty of our Credit Facility, we had a net worth of $953.3 million, asset coverage on our senior securities representing indebtedness of 204.4%, calculated in compliance with the requirements of Sections 18 and 61 of the 1940 Act, and an active status as a BDC and RIC. As of March 31, 2025, we were in compliance with all covenants under our Credit Facility.

Fair Value

We elected to apply the fair value option of ASC Topic 825, “Financial Instruments,” to the Credit Facility, which was consistent with our application of ASC 820 to our investments. Generally, the fair value of our Credit Facility is determined using a yield analysis, which includes a DCF calculation and also takes into account the assumptions the Valuation Team believes market participants would use, including the estimated remaining life, counterparty credit risk, current market yield and interest rate spreads of similar securities as of the measurement date. At March 31, 2025, the discount rate used to determine the fair value of our Credit Facility was 30-day Term SOFR, with a 0.35% floor, plus 3.25% per annum, plus an unused commitment fee of 1.0%. At March 31, 2024, the discount rate used to determine the fair value of our Credit Facility was 30-day Term SOFR, with a 0.35% floor, plus 3.25% per annum, plus an unused commitment fee of 1.0%. Generally, an increase or decrease in the discount rate used in the DCF calculation may result in a corresponding decrease or increase, respectively, in the fair value of our Credit Facility. At each of March 31, 2025 and 2024, our Credit Facility was valued using Level 3 inputs and any changes in its fair value are recorded in Net unrealized appreciation (depreciation) of other on our accompanying Consolidated Statements of Operations.

The following tables provide relevant information and disclosures aboutour Credit Facility as of and for the years ended March 31, 2025 and 2024, as required by ASC 820:

Common Equity Offerings

In May 2024, we entered into equity distribution agreements with Oppenheimer & Co., B. Riley Securities, Inc. and Virtu Americas LLC (collectively, the "Sales Agents"), under which we have the ability to issue and sell shares of our common stock, from time to time, through the Sales Agents, having an aggregate offering price of up to $75.0 million in what is commonly referred to as an “at-the-market” program (the “2024 Common Stock ATM Program”). As of March 31, 2025, we had remaining capacity to sell up to an additional $73.0 million of common stock under the 2024 Common Stock ATM Program.

In August 2022, we entered into equity distribution agreements with Oppenheimer & Co. and Virtu Americas LLC (each a “2022 Sales Agent”), under which we had the ability to issue and sell shares of our common stock, from time to time, through the 2022 Sales Agents, up to an aggregate offering price of $50.0 million in what is commonly referred to as an “at-the-market” program (“2022 Common Stock ATM Program”). In August 2023, we entered into an equity distribution agreement with B. Riley Securities, Inc. and entered into amendments to the agreements with Oppenheimer & Co. Inc. and Virtu Americas LLC to add B. Riley Securities, Inc. as a 2022 Sales Agent for the 2022 Common Stock ATM Program. We did not sell any shares under the 2022 Common Stock ATM Program, which terminated in connection with our entry into the 2024 Common Stock ATM Program on May 14, 2024, during the year ended March 31, 2025.

During the year ended March 31, 2025, we sold 148,714 shares of our common stock under the Common Stock ATM Program at a weighted-average gross price of $13.64 per share and raised approximately $2.0 million of gross proceeds. The weighted-average net price per share, after deducting commissions and offering costs borne by us, was $13.48 and resulted in total net proceeds of approximately $2.0 million. These sales were above our then current NAV per share.

During the year ended March 31, 2024, we sold 3,097,162 shares of our common stock under the 2022 Common Stock ATM Program at a weighted-average gross price of $14.37 per share and raised approximately $44.5 million of gross proceeds. The weighted-average net price per share, after deducting commissions and offering costs borne by us, was $14.12 and resulted in total net proceeds of approximately $43.7 million. These sales were above our then current NAV per share.

During the year ended March 31, 2023, we sold 386,482 shares of our common stock under the 2022 Common Stock ATM Program at a weighted-average gross price of $14.21 per share and raised approximately $5.5 million of gross proceeds. The weighted-average net price per share, after deducting commissions and offering costs borne by us, was $14.01 and resulted in total net proceeds of approximately $5.4 million. These sales were above our then current NAV per share.

NOTE 7. NET INCREASE (DECREASE) IN NET ASSETS RESULTING FROM OPERATIONS PER WEIGHTED-AVERAGE COMMON SHARE

The following table sets forth the computation of basic and diluted net increase in net assets resulting from operations per weighted-average common share for the years ended March 31, 2025, 2024, and 2023:

NOTE 8. DISTRIBUTIONS TO COMMON STOCKHOLDERS

To qualify to be taxed as a RIC under Subchapter M of the Code, we must generally distribute to our stockholders, for each taxable year, at least 90% of our Investment Company Taxable Income. The amount to be paid out as distributions to our stockholders is determined by our Board of Directors and is based upon management’s estimate of Investment Company Taxable Income and net long-term capital gains, as well as amounts to be distributed in accordance with Section 855(a) of the Code. Based on that estimate, our Board of Directors declares monthly distributions, and supplemental distributions, as appropriate, to stockholders each quarter and deemed distributions of long-term capital gains annually as of the end of the fiscal year, as applicable.

The U.S. federal income tax characteristics of cash distributions paid to our common stockholders generally are reported to stockholders on IRS Form 1099 after the end of each calendar year. Estimates of tax characterization made on a quarterly basis may not be representative of the actual tax characterization of cash distributions for the full year. Estimates made on a quarterly basis are updated as of each interim reporting date. The tax characterization of cash distributions paid to common stockholders during the calendar year ended December 31, 2024 was 52.9% from ordinary income and 47.1% from capital gains. The tax characterization of cash distributions paid to common stockholders during the calendar year ended December 31, 2023 was 53.2% from ordinary income and 46.8% from capital gains.

We paid the following cash distributions to our common stockholders for the years ended March 31, 2025, 2024 and 2023.

For the Year Ended March 31, 2025:

For the Year Ended March 31, 2024:

For the Year Ended March 31, 2023:

Aggregate cash distributions to our common stockholders declared and paid for the years ended March 31, 2025, 2024 and 2023 were $61.0 million, $76.1 million, and $47.0 million, respectively.

For the fiscal years ended March 31, 2025, 2024, and 2023, Investment Company Taxable Income exceeded distributions declared and paid, and, in accordance with Section 855(a) of the Code, we elected to treat $36.7 million, $18.7 million, and $21.4 million, respectively, of the first distributions paid subsequent to fiscal year-end, as having been paid in the prior year. In addition, for the fiscal years ended March 31, 2025, 2024, and 2023, net capital gains exceeded distributions declared and paid, and, in accordance with Section 855(a) of the Code, we elected to treat $18.7 million, $1.4 million, and $10.6 million, respectively, of the first distributions paid subsequent to fiscal year-end as having been paid in the prior year.

We may distribute our net long-term capital gains, if any, in cash or elect to retain some or all of such gains, pay taxes at the U.S. federal corporate-level income tax rate on the amount retained, and designate the retained amount as a “deemed distribution.” If we elect to retain net long-term capital gains and deem them distributed, each U.S. common stockholder will be treated as if they received a distribution of their pro-rata share of the retained net long-term capital gain and the U.S. federal income tax paid. As a result, each U.S. common stockholder will (i) be required to report their pro-rata share of the retained gain on their tax return as long-term capital gain, (ii) receive a refundable tax credit for their pro-rata share of federal income tax paid by us on the retained gain, and (iii) increase the tax basis of their shares of common stock by an amount equal to the deemed distribution less the tax credit. To use the deemed distribution approach, we must provide written notice to our common stockholders prior to the expiration of 60 days after the close of the relevant taxable year. For the years ended March 31, 2025, 2024, and 2023 we did not elect to retain long-term capital gains and to treat them as deemed distributions to common stockholders.

The components of our net assets on a tax basis were as follows:

For the years ended March 31, 2025 and 2024, we recorded the following adjustments for estimated permanent book-tax differences to reflect tax character. Results of operations, total net assets, and cash flows were not affected by these adjustments.

NOTE 9. FEDERAL AND STATE INCOME TAXES

We intend to continue to maintain our qualifications as a RIC for federal income tax purposes. As a RIC, we generally are not subject to federal income tax on the portion of our taxable income and gains that we distribute to stockholders. To maintain our qualification as a RIC, we must maintain our status as a BDC and meet certain source-of-income and asset diversification requirements. In addition, to qualify to be taxed as a RIC, we must distribute to stockholders at least 90% of our Investment Company Taxable Income. Our policy generally is to make distributions to our stockholders in an amount up to 100% of our Investment Company Taxable Income. We may retain some or all of our net long-term capital gains, if any, and designate them as deemed distributions, or distribute such gains to stockholders in cash. Because we have distributed or intend to distribute 100% of our Investment Company Taxable Income and net long-term capital gains, no income tax provisions have been recorded for the years ended March 31, 2025, 2024, and 2023.

In an effort to limit federal excise taxes, we have to distribute to stockholders, during each calendar year, an amount close to the sum of (1)98% of our ordinary income for the calendar year, (2)98.2% of our net capital gains (both long-term and short-term), if any, for the one-year period ending on October 31 of the calendar year and (3)any income realized, but not distributed, in the preceding period (to the extent that income tax was not imposed on such amounts), less certain reductions, as applicable. We incurred an excise tax of $1.2 million, $1.2 million, and $1.3 million for the calendar years ended December 31, 2024, 2023 and 2022, respectively, which are included in Other general and administrative expenses on the accompanying Consolidated Statement of Operations.

Under the RIC Modernization Act, we are permitted to carryforward any capital losses that we may incur for an unlimited period, and such capital loss carryforwards will retain their character as either short-term or long-term capital losses. Our capital loss carryforward balance was $0 as of both March 31, 2025 and 2024.

NOTE 10. COMMITMENTS AND CONTINGENCIES

We are party to certain legal proceedings incidental to the normal course of our business. We are required to establish reserves for litigation matters where those matters present loss contingencies that are both probable and estimable. When loss contingencies are not both probable and estimable, we do not establish reserves. Based on current knowledge, we do not believe that loss contingencies, if any, arising from pending investigations, litigation or regulatory matters will have a material adverse effect on our financial condition, results of operation or cash flows. Additionally, based on our current knowledge, we do not believe such loss contingencies are both probable and estimable and, therefore, as of March 31, 2025 and 2024, we had no established reserves for such loss contingencies.

Escrow Holdbacks

From time to time, we enter into arrangements relating to exits of certain investments whereby specific amounts of the proceeds are held in escrow to be used to satisfy potential obligations, as stipulated in the sales agreements. We record escrow amounts in Restricted cash and cash equivalents and Other liabilities, if received in cash but subject to potential obligations or other contractual restrictions, or as escrow receivables in Other assets, net, if not yet received in cash, on our accompanying Consolidated Statements of Assets and Liabilities. We establish reserves and holdbacks against escrow amounts if we determine that it is probable and estimable that a portion of the escrow amounts will not ultimately be released or received at the end of the escrow period. Reserves and holdbacks against escrow amounts were $1.0 million and $1.0 million as of March 31, 2025 and 2024, respectively.

Financial Commitments and Obligations

We may have line of credit commitments to certain of our portfolio companies that have not been fully drawn. Since these line of credit commitments have expiration dates and we expect many will never be fully drawn, the total line of credit commitment amounts do not necessarily represent future cash requirements. We estimate the fair value of the combined unused line of credit commitments as of March 31, 2025 and 2024 to be insignificant.

We may also extend guaranties on behalf of our portfolio companies. As of March 31, 2025 and 2024, there were no guaranties outstanding.

The following table summarizes the principal balances of unused line of credit as of March 31, 2025 and 2024, which are not reflected as liabilities in the accompanying Consolidated Statements of Assets and Liabilities:

NOTE 11. FINANCIAL HIGHLIGHTS

(A)Based on actual shares of common stock outstanding at the beginning or end of the corresponding year, as appropriate.

(B)Based on weighted-average basic common share data for the corresponding year.

(C)The tax character of distributions is determined based on taxable income calculated in accordance with income tax regulations, which may differ from amounts determined under GAAP. For further information on the estimated character of our distributions to common stockholders, including changes in estimates, as applicable, refer to Note 8 —Distributions to Common Stockholders.

(D)During the years ended March 31, 2024, 2023, and 2020, the accretive effect is the result of issuing common shares at a price above the then current NAV per share. During the years ended March 31, 2018 and 2016, the net dilutive effect is the result of issuing common shares at a price below the then current NAV per share.

(E)Represents the impact of the different share amounts (weighted-average basic common shares outstanding for the corresponding year and actual common shares outstanding at the end of the year) in the Per Common Share Data calculations and rounding impacts.

(F)Total investment return equals the change in the market value of our common stock from the beginning of the year, taking into account dividends reinvested in accordance with the terms of our dividend reinvestment plan. Total return does not take into account distributions that may be characterized as a return of capital. For further information on the estimated character of our distributions to common stockholders, including changes in estimates, as applicable, refer to Note 8 —Distributions to Common Stockholders.

(G)Calculated using the average balance of net assets at the end of each month of the reporting year.

(H)Represents the aggregate liquidation preference of our mandatorily redeemable preferred stock.

(I)Ratio of net expenses to average net assets is computed using total expenses, net of any non-contractual, unconditional, and irrevocable credits of fees from the Adviser. Had we not received any non-contractual, unconditional, and irrevocable credits of fees from the Adviser, the ratio of expenses to average net assets would have been 16.79%,17.38%,12.58%,16.72%,13.33%,9.12%,16.45%,14.11%,13.46%, and 14.50% for the fiscal years ended March 31, 2025, 2024, 2023, 2022, 2021, 2020, 2019, 2018, 2017 and 2016, respectively.

Had we included Virginia state taxes incurred on the deemed distributions of retained capital gains for the fiscal years ended March 31, 2020 and 2019, the ratio of net expenses to average net assets would have been 6.89% and 14.07%, respectively.

(J)Had we not received any non-contractual, unconditional, and irrevocable credits of fees from the Adviser, the ratio of net investment income (loss) to average net assets would have been 2.79%,1.53%,5.66%,0.31%,2.16%,6.20%, (1.22%),3.66%,4.19%, and 3.94% for the fiscal years ended March 31, 2025, 2024, 2023, 2022, 2021, 2020, 2019, 2018, 2017 and 2016, respectively.

NOTE 12. UNCONSOLIDATED SIGNIFICANT SUBSIDIARIES

In accordance with the SEC’s Regulation S-X, we do not consolidate portfolio company investments. Further, in accordance with ASC 946, we are precluded from consolidating any entity other than another investment company, except that ASC 946 provides for the consolidation of a controlled operating company that provides substantially all of its services to the investment company or its consolidated subsidiaries.

We did not have any unconsolidated subsidiaries that met any of the significance conditions under Rule 1-02(w)(2) of the SEC’s Regulation S-X as of or during the years ended March 31, 2025, 2024 and 2023.

NOTE 13. SUBSEQUENT EVENT
