GLADSTONE CAPITAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

JUNE 30, 2025

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

NOTE 1. ORGANIZATION

Gladstone Capital Corporation was incorporated under the Maryland General Corporation Law on May 30, 2001 and completed an initial public offering on August 24, 2001. The terms “the Company,” “we,” “our” and “us” all refer to Gladstone Capital Corporation 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 the 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 operating in the United States (“U.S.”). Our investment objectives are to: (1) achieve and grow current income by investing in debt securities of established lower middle market companies (which we generally define as companies with annual earnings before interest, taxes, depreciation and amortization (“EBITDA”) of $ 3 million to $ 25 million) in the U.S. 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 (2) provide our stockholders with long-term capital appreciation in the value of our assets by investing in equity securities, in connection with our debt investments, that we believe can grow over time to permit us to sell our equity investments for capital gains.

Gladstone Business Loan, LLC (“Business Loan”), a wholly-owned subsidiary of ours, was established on February 3, 2003, for the sole purpose of holding certain investments pledged as collateral under our line of credit. The financial statements of Business Loan are consolidated with those of Gladstone Capital Corporation. We may also have significant subsidiaries (as defined under Rule 1-02(w)(2) of the U.S. Securities and Exchange Commission’s (“SEC”) Regulation S-X) whose financial statements are not consolidated with ours. 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 three and nine month periods ended June 30, 2025 and June 30, 2024.

We are externally managed by Gladstone Management Corporation (the “Adviser”), an affiliate of ours and an SEC registered investment adviser, pursuant to an investment advisory and management agreement (as amended and/or restated from time to time, 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 additional information regarding these arrangements.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Unaudited Interim Financial Statements and Basis of Presentation

We prepare our interim financial statements in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Articles 6, 10 and 12 of Regulation S-X. Accordingly, we have not included in this quarterly report all of the information and notes required by GAAP for annual financial statements. The accompanying Consolidated Financial Statements include our accounts and those of our wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in 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. In our opinion, all adjustments, consisting solely of normal recurring accruals, necessary for the fair statement of financial statements for the interim periods have been included. The results of operations for the three and nine months ended June 30, 2025 are not necessarily indicative of results that ultimately may be achieved for the fiscal year ending

Table of Contents

September 30, 2025 or any future interim periods. The interim financial statements and notes thereto should be read in conjunction with the financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024, as filed with the SEC on November 13, 2024.

Retroactive Adjustments for Reverse Stock Split

The outstanding shares and per share amounts of the Company’s common stock in the consolidated financial statements and notes to the consolidated financial statements have been retroactively adjusted for the 1-for-2 reverse stock split (the “Reverse Stock Split”) effected on April 4, 2024 (effective April 5, 2024 for trading purposes) for all activity prior to that date.

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 is 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 $ 14.9 million and $ 2.2 million of cash equivalents in Dreyfus Treasury Obligations Cash Management fund as of June 30, 2025 and September 30, 2024, respectively. Investments in money market funds represent Level 1 investments within the FASB ASC Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”) fair value hierarchy.

Investment Valuation Policy

Accounting Recognition

We record our investments at fair value in accordance with 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, in July 2022, 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.

Table of Contents

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 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 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 our third party valuation firm and market quotes.

Table of Contents

• 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 (“IBP”) 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.

Revenue Recognition

Interest Income Recognition

Interest income, including the amortization of premiums, acquisition costs and amendment fees, the accretion of original issue discounts (“OID”), and paid-in-kind (“PIK”) interest, 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 for financial reporting purposes 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 such that the interest income is deemed to be collectible. As of June 30, 2025, our loans to B+T Group Acquisition, Inc., Edge Adhesives Holdings, Inc., and WB Xcel Holdings, LLC were on non-accrual status with a cost basis of $ 28.8 million, or 4.1 % of the cost basis of all debt investments in our portfolio, and a fair value of $ 11.5 million, or 1.7 % of the fair value of all debt investments in our portfolio. As of September 30, 2024, our loans to B+T Group Acquisition, Inc., Edge Adhesives Holdings, Inc., and WB Xcel Holdings, LLC were on non-accrual status with a cost basis of $ 28.3 million, or 4.1 % of the cost basis of all debt investments in our portfolio, and a fair value of $ 12.8 million, or 1.9 % of the fair value of all debt investments in our portfolio.

We currently hold, and we expect to hold in the future, some loans in our portfolio that contain OID or PIK provisions. We recognize OID for loans originally issued at discounts and recognize the income over the life of the obligation based on an

Table of Contents

effective yield calculation. PIK interest, computed at the contractual rate specified in a loan agreement, is added to the principal balance of a loan and recorded as income over the life of the obligation. Thus, the actual collection of PIK income may be deferred until the time of debt principal repayment. To maintain our ability to be taxed as a RIC, we may need to pay out both OID and PIK non-cash income amounts in the form of distributions, even though we have not yet collected the cash on either.

As of each of June 30, 2025 and September 30, 2024, we held two OID loans. We recorded OID income of $ 0.2 million and $ 0.4 million during the three and nine months ended June 30, 2025, respectively, and $ 0.1 million and $ 0.2 million during the three and nine months ended June 30, 2024, respectively. The unamortized balance of OID investments as of June 30, 2025 and September 30, 2024 totaled $ 0.3 million and $ 0.6 million, respectively. As of June 30, 2025 and September 30, 2024, we had seven and eight investments which had a PIK interest component, respectively. We recorded PIK interest income of $ 1.3 million and $ 3.0 million during the three and nine months ended June 30, 2025, respectively, and $ 1.5 million and $ 4.3 million during the three and nine months ended June 30, 2024, respectively. We collected $ 0 and $ 7.2 million of PIK interest in cash during the three and nine months ended June 30, 2025, respectively, and $ 0.2 million during each of the three and nine months ended June 30, 2024.

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.

Related Party Fees

We are party to the Advisory Agreement with the Adviser, which is indirectly owned 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 our revolving line of credit with KeyBank National Association (“KeyBank”), as administrative agent, lead arranger and lender (as amended and/or restated from time to time, our “Credit Facility”). These fees are accrued at the end of the quarter when the services are performed and generally paid the following quarter.

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 Transactions for additional information regarding these related party fees and agreements.

NOTE 3. INVESTMENTS

Fair Value

In accordance with ASC 820, the fair value of each investment 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 in those 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. Investments in funds measured using NAV as a practical expedient are not categorized within the fair value hierarchy.

As of June 30, 2025, all of our investments were valued using Level 3 inputs within the ASC 820 fair value hierarchy, except for our investments in Gladstone Alternative Income Fund (“Gladstone Alternative”) and Leeds Novamark Capital I, L.P. (“Leeds”), which were valued using NAV as a practical expedient. As of September 30, 2024, all of our investments were valued using Level 3 inputs within the ASC 820 fair value hierarchy, except for our investment in Leeds, which was valued using NAV as a practical expedient.

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. During the nine months ended June 30, 2025 and 2024, there were no investments transferred into or out of Levels 1, 2 or 3 of the valuation hierarchy.

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, respectively, in the fair value of certain of our investments.

NOTE 4. RELATED PARTY TRANSACTIONS

Transactions with the Adviser

We have been externally managed by the Adviser pursuant to the Advisory Agreement since October 1, 2004 pursuant to which we pay the Adviser a base management fee and an incentive fee for its services. Our Board of Directors, including a majority of the directors who are not parties to the Advisory Agreement or interested persons of us or the Adviser, unanimously approved the Advisory Agreement.

Table of Contents

We also pay the Adviser a loan servicing fee for its role of servicer pursuant to our Credit Facility. The entire loan servicing fee paid to the Adviser by Business Loan is non-contractually, unconditionally and irrevocably credited against the base management fee otherwise payable to the Adviser, since Business Loan is a consolidated subsidiary of ours, and overall, the base management fee (including any loan servicing fee) cannot exceed 1.75 % of total assets (including investments made with proceeds of borrowings, less any uninvested cash or cash equivalents resulting from borrowings) during any given fiscal year pursuant to the Advisory Agreement.

David Gladstone (our chairman and chief executive officer) serves as a director and executive officer of the Adviser, which, as of June 30, 2025, is 100 % indirectly owned by Mr. Gladstone. Robert Marcotte (our president) also serves as executive vice president of private equity of the Adviser. Michael LiCalsi, our chief administrative officer, co-general counsel, and co-secretary, also serves in the same roles for our Adviser and Administrator (in addition to serving as president of our Administrator). Effective July 10, 2025, Erich Hellmold was appointed as our co-general counsel and co-secretary. He was also appointed to the same roles for our Adviser and Administrator.

The following table summarizes the base management fee, incentive fee, and loan servicing fee 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 period.

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

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 1.75 %, computed on the basis of the value of our average total 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 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

Table of Contents

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 for such services against the base management fee that we would otherwise be required to pay to the Adviser.

Our Board of Directors accepted a non-contractual, unconditional, and irrevocable credit from the Adviser to reduce the annual base management fee on syndicated loan participations to 0.5 %, to the extent that proceeds resulting from borrowings were used to purchase such syndicated loan participations, for each of the three and nine months ended June 30, 2025 and 2024.

Loan Servicing Fee

The Adviser also services the loans held by Business Loan (the borrower under the Credit Facility), in return for which the Adviser receives a 1.5 % annual fee payable monthly based on the aggregate outstanding balance of loans pledged under our Credit Facility. As discussed in the notes to the table above, 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 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 % ( 2.0 % during the period from April 1, 2020 through March 31, 2023) 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 generally 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 % ( 2.50 % from April 1, 2022 through March 31, 2023) 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 % ( 2.50 % from April 1, 2022 through March 31, 2023) 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 “net realized capital gains” (as defined herein) as of the end of the fiscal year. In determining the capital gains-based incentive fee payable to the Adviser, we calculate “net realized capital gains” at the end of each applicable year by subtracting the sum of our cumulative aggregate realized capital losses and our entire portfolio’s aggregate unrealized capital depreciation from our cumulative aggregate realized capital gains. For this purpose, cumulative aggregate realized capital gains, if any, equals the sum of the differences between the net sales price of each investment, when sold, and the original cost of such investment since inception. Cumulative aggregate realized capital losses equals the sum of the amounts by which the net sales price of each investment, when sold, is less than the original cost of such investment since inception. The entire portfolio’s aggregate unrealized capital depreciation, if any, equals the sum of the difference between the valuation of each investment as of the applicable calculation date and the original cost of such investment. At the end of the applicable fiscal year, the amount of capital gains that serves as the basis for our calculation of the capital gains-based incentive fee equals the cumulative aggregate realized capital gains less cumulative aggregate realized capital losses, less the entire portfolio’s aggregate unrealized capital depreciation, if any. If this number is positive at the end of such fiscal year, 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. No capital gains-based incentive fee has been recorded or paid since our inception through June 30, 2025, as cumulative unrealized capital depreciation has exceeded cumulative realized capital gains net of cumulative realized capital losses.

Table of Contents

In accordance with GAAP, a capital gains-based incentive fee accrual is calculated using the aggregate cumulative realized capital gains and losses and aggregate cumulative unrealized capital appreciation and depreciation. If such amount is positive at the end of a period, then GAAP requires us to record a capital gains-based incentive fee equal to 20.0 % of such amount, less the aggregate amount of actual capital gains-based incentive fees paid in all prior years. If such amount is negative, then there is no accrual for such period. GAAP requires that the capital gains-based incentive fee accrual consider the cumulative 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 such unrealized capital appreciation will be realized in the future. No GAAP accrual for a capital gains-based incentive fee has been recorded from our inception through June 30, 2025.

Our Board of Directors accepted non-contractual, unconditional and irrevocable credits from the Adviser to reduce the income-based incentive fee to the extent net investment income did not cover 100.0 % of distributions to common stockholders for the three and nine months ended June 30, 2025 and 2024.

Transactions with the Administrator

We have entered into the Administration Agreement with the Administrator to provide administrative services. We reimburse the Administrator pursuant to the Administration Agreement for the portion of expenses the Administrator incurs while performing services for us. The Administrator’s expenses are primarily rent and the salaries, benefits and expenses of the Administrator’s employees, including: our chief financial officer and treasurer, chief compliance officer, chief valuation officer, and co-general counsels and co-secretaries and their respective staffs. David Gladstone (our chairman and chief executive officer) serves as a member of the board of managers and executive officer of the Administrator, which, as of June 30, 2025, is 100 % indirectly owned and controlled by Mr. Gladstone. Another of our officers, Michael LiCalsi, our chief administrative officer, co-general counsel and co-secretary, also serves in the same roles for our Adviser and Administrator (in addition to serving as president of our Administrator). Effective July 10, 2025, Erich Hellmold was appointed as our co-general counsel and co-secretary. He was also appointed to the same roles for our Adviser and Administrator.

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 10, 2025, 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 renewal of the Administration Agreement through August 31, 2026.

Transactions with Gladstone Securities, LLC

Gladstone Securities, LLC (“Gladstone Securities”), a privately-held broker-dealer registered with the Financial Industry Regulatory Authority and insured by the Securities Investor Protection Corporation, which is 100 % indirectly owned and controlled by Mr. Gladstone, our chairman and chief executive officer, has provided other services, such as investment banking and due diligence services, to certain of our portfolio companies, for which Gladstone Securities 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 or incentive fee. Gladstone Securities received fees from portfolio companies totaling $ 0.1 million and $ 0.5 million during the three and nine months ended June 30, 2025, respectively, and $ 0.2 million and $ 0.3 million during the three and nine months ended June 30, 2024, respectively.

We entered into a dealer manager agreement (the “Dealer Manager Agreement”) with Gladstone Securities pursuant to which Gladstone Securities serves as our exclusive dealer manager in connection with the offering of our Series A Preferred Stock (as defined in Note 6—Cumulative Redeemable Preferred Stock Offering). Under the Dealer Manager Agreement, Gladstone Securities provides certain sales, promotional and marketing services to us in connection with the offering of the Series A Preferred Stock (the “Series A Offering”), and we pay Gladstone Securities (i) selling commissions of up to 7.0 % of the gross proceeds from sales of Series A Preferred Stock in the offering, and (ii) a dealer manager fee of up to 3.0 % of the gross proceeds from sales of Series A Preferred Stock in the offering. Gladstone Securities may, in its sole discretion, reallow a portion of the dealer manager fee to participating broker-dealers in support of the Series A Offering. The terms of the Dealer Manager Agreement were approved by our board of directors, including its independent directors.

which are netted against gross proceeds from the sales. During the three and nine months ended June 30, 2024, we paid Gladstone Securities selling commissions and dealer manager fees totaling $ 0.4 million and $ 0.6 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.

These amounts are generally settled in the quarter subsequent to being incurred and are included in other liabilities on the accompanying Consolidated Statements of Assets and Liabilities as of June 30, 2025 and September 30, 2024.

NOTE 5. BORROWINGS

Revolving Line of Credit

On May 13, 2021, we, through Business Loan, entered into a sixth amended and restated credit agreement with KeyBank as administrative agent, lead arranger, managing agent and lender, the Adviser, as servicer, and certain other lenders party thereto (the “Credit Facility”). On June 23, 2025, we, through Business Loan, entered into Amendment No. 9 to the Credit Facility.

As of June 30, 2025, our Credit Facility had a total commitment amount of $ 320.0 million with an “accordion” feature that permits us to increase the size of the facility to $ 400.0 million. The Credit Facility has a revolving period end date of October 31, 2027, and a final maturity date of October 31, 2029 (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). The interest rate margin is 2.60 % during the revolving period and 3.10 % thereafter.

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

	June 30, 2025	September 30, 2024
Commitment amount	$ 320,000	$ 293,659
Line of credit outstanding, at cost	27,500	70,600
Availability (A)	277,744	200,381

For the Three Months Ended June 30, — 2025	2024	For the Nine Months Ended June 30, — 2025	2024

Table of Contents

Weighted average borrowings outstanding, at cost	$	$	$	$
Weighted average interest rate (B)	58.3 %	10.5 %	17.3 %	10.7 %
Commitment (unused) fees incurred	$ 724	$ 396	$ 2,013	$ 1,146

(A) Available borrowings are subject to various constraints imposed under our Credit Facility, based on the aggregate loan balance pledged by Business Loan, which varies as loans are added and repaid, regardless of whether such repayments are prepayments or made as contractually required.

(B) Includes unused commitment fees and excludes the impact of deferred financing costs.

Our Credit Facility also requires that any interest or 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 each 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 as of June 30, 2025 and September 30, 2024.

Our Credit Facility contains covenants that require Business Loan to maintain its status as a separate legal entity, prohibit certain significant corporate transactions (such as mergers, consolidations, liquidations or dissolutions), and restrict material changes to our credit and collection policies without the lenders’ consent. Our Credit Facility also generally limits distributions to our stockholders on a fiscal year basis to the sum of our net investment income, net capital gains and amounts elected to have been paid during the prior year in accordance with Section 855(a) of the Code. Business Loan is also subject to certain limitations on the type of loan investments it can apply as collateral towards the borrowing base to receive additional borrowing availability under our Credit Facility, including restrictions on geographic concentrations, sector concentrations, loan size, payment frequency and status, average life and lien property. Our Credit Facility further requires Business Loan to comply with other financial and operational covenants, which obligate Business Loan to, among other things, maintain certain financial ratios, including asset and interest coverage and a minimum number of 25 obligors required in the borrowing base.

Additionally, we are required to maintain (i) a minimum net worth (defined in our Credit Facility to include any outstanding redeemable preferred stock) of $ 500.0 million plus 50.0 % of all equity and subordinated debt raised after June 23 , 2025 less 50 % of any equity and subordinated debt retired or redeemed after June 23, 2025, which equates to $ 500.0 million as of June 30, 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 June 30, 2025, and as defined in our Credit Facility, we had a net worth of $ 727.0 million, asset coverage on our “senior securities representing indebtedness” of 267.9 %, calculated in accordance with the requirements of Section 18 and 61 of the 1940 Act, and an active status as a BDC and RIC. In addition, we had 33 obligors in our Credit Facility’s borrowing base as of June 30, 2025. As of June 30, 2025, we were in compliance with all of our Credit Facility covenants.

Fair Value

We elected to apply the fair value option of ASC 825, “ Financial Instruments ,” specifically for 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 the assumptions that 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. As of June 30, 2025, the discount rate used to determine the fair value of our Credit Facility was one-month Term SOFR, plus 2.60 % per annum, plus a 1.00 % unused commitment fee. As of September 30, 2024, the discount rate used to determine the fair value of our Credit Facility was one-month Term SOFR, plus 3.10 % per annum, plus a 1.00 % unused commitment fee. 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. As of June 30, 2025 and September 30, 2024, our Credit Facility was valued using Level 3 inputs and any changes in its fair value are recorded in net unrealized depreciation (appreciation) of other on our accompanying Consolidated Statements of Operations .

The fair value of the collateral under our Credit Facility totaled approximately $ 667.7 million and $ 714.4 million as of June 30, 2025 and September 30, 2024, respectively.

Notes Payable

In August 2023, we completed an offering of $ 57.0 million aggregate principal amount of 7.75 % Notes due 2028 (the “2028 Notes”) for net proceeds of approximately $ 55.1 million after deducting underwriting discounts, commissions and offering expenses borne by us. The 2028 Notes are traded under the ticker symbol “GLADZ” on the Nasdaq Global Select Market. The 2028 Notes will mature on September 1, 2028 and may be redeemed in whole or in part at any time or from time to time at our option on or after September 1, 2025. The 2028 Notes bear interest at a rate of 7.75 % per year. Interest is payable quarterly on March 1, June 1, September 1, and December 1 of each year (which equates to approximately $ 4.4 million per year).

In November 2021, we completed a private placement of $ 50.0 million aggregate principal amount of 3.75 % Notes due 2027 (the “2027 Notes”) for net proceeds of approximately $ 48.5 million after deducting initial purchasers’ costs, commissions and offering expenses borne by us. The 2027 Notes will mature on May 1, 2027 and may be redeemed in whole or in part at any time or from time to time at the Company’s option prior to maturity at par plus a “make-whole” premium, if applicable. The 2027 Notes bear interest at a rate of 3.75 % per year. Interest is payable semi-annually on May 1 and November 1 of each year (which equates to approximately $ 1.9 million per year).

(the “Exchange Notes”) that had been registered with the SEC under the Securities Act of 1933, as amended. The terms of the Exchange Notes are identical to those of the Restricted Notes, except that the transfer restrictions and registration rights relating to the Restricted Notes do not apply to the Exchange Notes, and the Exchange Notes do not provide for the payment of additional interest in the event of a registration default.

In December 2020, we completed an offering of $ 100.0 million aggregate principal amount of 5.125 % Notes due 2026 (the “2026 Notes”) for net proceeds of approximately $ 97.7 million after deducting underwriting discounts, commissions and offering expenses borne by us. In March 2021, we completed an offering of an additional $ 50.0 million aggregate principal amount of the 2026 Notes for net proceeds of approximately $ 50.6 million after adding premiums and deducting underwriting costs, commissions and offering expenses borne by us. The 2026 Notes will mature on January 31, 2026 and may be redeemed in whole or in part at any time or from time to time at the Company’s option prior to maturity at par plus a “make-whole” premium, if applicable. The 2026 Notes bear interest at a rate of 5.125 % per year. Interest is payable semi-annually on January 31 and July 31 of each year (which equates to approximately $ 7.7 million per year).

The indenture relating to the 2028 Notes, the 2027 Notes, and the 2026 Notes contains certain covenants, including (i) an inability to incur additional debt or issue additional debt or preferred securities unless the Company’s asset coverage meets the threshold specified in the 1940 Act after such borrowing, (ii) an inability to declare any dividend or distribution (except a dividend payable in our stock) on a class of our capital stock or to purchase shares of our capital stock unless the Company’s asset coverage meets the threshold specified in the 1940 Act at the time of (and giving effect to) such declaration or purchase, and (iii) if, at any time, we are not subject to the reporting requirements of the Exchange Act, we will provide the holders of the 2028 Notes, the 2027 Notes, and the 2026 Notes, as applicable, and the trustee with audited annual consolidated financial statements and unaudited interim consolidated financial statements.

The 2028 Notes, 2027 Notes, and 2026 Notes are recorded at the principal amount, plus applicable premiums, less discounts and offering costs, on our Consolidated Statements of Assets and Liabilities.

The fair value, based on the last quoted closing price, of the 2028 Notes as of June 30, 2025 was $ 58.3 million. We consider the trading price of the 2028 Notes to be a Level 1 input within the ASC 820 hierarchy. The fair value, based on a DCF analysis, of the 2027 Notes as of June 30, 2025 was $ 47.7 million. The fair value, based on a DCF analysis, of the 2026 Notes as of June 30, 2025 was $ 148.8 million. We consider the 2027 Notes and 2026 Notes to be Level 3 within the ASC 820 fair value hierarchy.

NOTE 6. CUMULATIVE REDEEMABLE PREFERRED STOCK OFFERING

In May 2023, we entered into a Dealer Manager Agreement pursuant to which we may sell a maximum of 6,000,000 shares of 6.25 % Series A Cumulative Redeemable Preferred Stock (the “Series A Preferred Stock”), par value $ 0.001 per share, on a “reasonable best efforts” basis through our affiliated dealer manager, Gladstone Securities, at a public offering price of $ 25.00 per share. Pursuant to the Dealer Manager Agreement, the offering will terminate on the date that is the earlier of (1) December 31, 2026 (unless earlier terminated or extended by our Board of Directors) and (2) the date on which all 6,000,000 shares of Series A Preferred Stock offered are sold. See Note 4, Related-Party Transactions—Other Transactions , for a discussion of the commissions and fees to be paid to Gladstone Securities in connection with the Series A Offering.

The Series A Preferred Stock is currently being sold pursuant to our shelf registration statement on Form N-2 (File No. 333-275934) (the “2024 Registration Statement”), under the Securities Act of 1933, as amended, and a prospectus supplement, dated November 22, 2024, and a base prospectus dated January 17, 2024. As of June 30, 2025, we had a remaining capacity to sell up to an additional 5,352,180 of Series A Preferred Shares under the Dealer Manager Agreement.

During the three and nine months ended June 30, 2025, we sold 127,427 and 300,689 shares of Series A Preferred Stock, respectively, for gross proceeds of $ 3.2 million and $ 7.5 million, respectively, and net proceeds of $ 2.9 million and $ 6.7 million, respectively. During the three and nine months ended June 30, 2024, we sold 179,473 and 249,517 shares of Series A Preferred Stock, respectively, for gross proceeds of $ 4.5 million and $ 6.2 million, respectively, and net proceeds of $ 4.0 million and $ 5.6 million, respectively.

There were no redemptions of Series A Preferred Stock during the three and nine months ended June 30, 2024. There were 647,820 and 349,931 shares of Series A Preferred Stock outstanding as of June 30, 2025 and September 30, 2024, respectively.

Table of Contents

In accordance with ASC 480-10-S99-3A, the Company’s Series A Preferred Stock has been classified in temporary equity on the Consolidated Statements of Assets and Liabilities . The Series A Preferred Stock is recorded net of offering and issuance costs. Dividend payments to our preferred stockholders are included in preferred stock dividends on our Consolidated Statements of Operations, which totaled $ 0.2 million and $ 0.6 million during the three and nine months ended June 30, 2025, respectively, and $ 88 thousand and $ 96 thousand during the three and nine months ended June 30, 2024, respectively.

We may be required to mandatorily redeem some or all of the shares of our Series A Preferred Stock if we fail to maintain asset coverage of at least the minimum amount required by Sections 18 and 61 of the 1940 Act (which is currently 150%). The asset coverage on our “senior securities that are stock” as of June 30, 2025 was 253.7 %, calculated in accordance with Sections 18 and 61 of the 1940 Act.

We paid cash dividends of $ 0.130208 per share to holders of our Series A Preferred Stock for each month during the three and nine months ended June 30, 2025.

NOTE 7. REGISTRATION STATEMENT AND COMMON EQUITY OFFERINGS

Reverse Stock Split

On April 4, 2024, we completed a 1-for-2 Reverse Stock Split of the Company’s issued and outstanding common stock, by the filing of Articles of Amendment with the State Department of Assessments and Taxation of Maryland pursuant to the Maryland General Corporation Law. The Reverse Stock Split became effective at 4:05 p.m. Eastern Time on April 4, 2024. The Reverse Stock Split was effective for purposes of trading as of the opening of business on the Nasdaq Global Select Market on April 5, 2024.

As a result of the Reverse Stock Split, every two shares of common stock issued and outstanding were automatically combined into one new share of common stock. The Reverse Stock Split did not modify any rights or preferences of the shares of common stock. The common stock issued pursuant to the Reverse Stock Split remains fully paid and non-assessable. The Reverse Stock Split did not affect the number of authorized shares of common stock or the par value of the common stock.

Common Stock At-the-Market Offerings

In August 2024, we entered into an equity distribution agreement with Jefferies LLC and Huntington Securities, Inc, under which we have the ability to issue and sell, from time to time, shares of our common stock with an aggregate offering price of up to $ 150.0 million in an “at the market offering” (the “2024 ATM Program”). During the three and nine months ended June 30, 2025, we sold 0 and 99,265 shares of our common stock, respectively, under the 2024 ATM Program, at a weighted-average price of $ 24.90 per share and raised $ 2.5 million of gross proceeds. Net proceeds, after deducting commissions and offering costs borne by us, were approximately $ 2.4 million. As of June 30, 2025, we had a remaining capacity to sell up to an additional $ 136.5 million of our common stock under the 2024 ATM Program.

Shelf Registration Statement

Our 2024 Registration Statement, which was declared effective on January 17, 2024, permits us to issue, through one or more transactions, up to an aggregate of $ 700.0 million in securities, consisting of common stock, preferred stock, subscription rights, debt securities and warrants to purchase common stock or preferred stock. As of June 30, 2025, we had the ability to issue up to $ 681.3 million in securities under the 2024 Registration Statement.

Basic and diluted net increase (decrease) in net assets resulting from operations per common share	$ 0.33	$ 0.88	$ 1.93	$ 2.88

NOTE 9. 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 taxable ordinary income plus the excess of our net short-term capital gains over net long-term capital losses (“Investment Company Taxable Income”). The amount to be paid out as distributions to our stockholders is determined by our Board of Directors quarterly and is based on management’s estimate of Investment Company Taxable Income. Based on that estimate, our Board of Directors declares three monthly distributions to common stockholders each quarter.

The federal income tax characteristics of all distributions will be reported to stockholders on the 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.

For the calendar year ended December 31, 2024, 83.1 % of distributions to common stockholders were deemed to be paid from ordinary income and 16.9 % were deemed to be paid from capital gains for 1099 stockholder reporting purposes. For the calendar year ended December 31, 2023, 100.0 % of distributions to common stockholders were deemed to be paid from ordinary income for 1099 stockholder reporting purposes.

Aggregate distributions declared and paid to our common stockholders were approximately $ 42.1 million and $ 32.3 million for the nine months ended June 30, 2025 and 2024 , respectively, and were declared based on estimates of Investment Company Taxable Income. For the fiscal year ended September 30, 2024, our current and accumulated earnings and profits exceeded common stock distributions declared and paid, and, in accordance with Section 855(a) of the Code, we elected to treat $ 6.6 million of the first common distributions paid to common stockholders in the subsequent fiscal year as having been paid in the prior year.

NOTE 10. COMMITMENTS AND CONTINGENCIES

Legal Proceedings

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 operations 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 June 30, 2025 and September 30, 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, 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 $ 1.5 million and $ 0.1 million as of June 30, 2025 and September 30, 2024, respectively.

Financial Commitments and Obligations

We have lines of credit, delayed draw term loans, and an uncalled capital commitment with certain of our portfolio companies that have not been fully drawn. Since these commitments have expiration dates and we expect many will never be fully drawn, the total commitment amounts do not necessarily represent future cash requirements. We estimate the fair value of the combined unused lines of credit, the unused delayed draw term loans and the uncalled capital commitment as of June 30, 2025 and September 30, 2024 to be immaterial.

The following table summarizes the amounts of our unused lines of credit, delayed draw term loans and uncalled capital commitment, at cost, as of June 30, 2025 and September 30, 2024, which are not reflected as liabilities in the accompanying Consolidated Statements of Assets and Liabilities :

	June 30, 2025	September 30, 2024
Unused line of credit commitments (A)	$ 40,326	$ 42,601
Delayed draw term loans (A)	7,500	14,150

OVERVIEW

General

We were incorporated under the Maryland General Corporation Law on May 30, 2001. We operate as an externally managed, closed-end, non-diversified management investment company, and have elected to be treated as a BDC under the 1940 Act. In addition, for federal income tax purposes we have elected to be treated as a RIC under the Code. To continue to qualify as a RIC for federal income tax purposes and obtain favorable RIC tax treatment, we must meet certain requirements, including certain minimum distribution requirements.

Table of Contents

We were established for the purpose of investing in debt and equity securities of established private businesses operating in the U.S. Our investment objectives are to: (1) achieve and grow current income by investing in debt securities of established lower middle market companies in the U.S. 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 (2) provide our stockholders with long-term capital appreciation in the value of our assets by investing in equity securities, in connection with our debt investments, that we believe can grow over time to permit us to sell our equity investments for capital gains. To achieve our investment objectives, our primary investment strategy is to invest in several categories of debt and equity securities, with each investment generally ranging from $8 million to $40 million, although investment size may vary, depending upon our total assets or available capital at the time of investment. We expect that our investment portfolio over time will consist of approximately 90.0% debt investments and 10.0% equity investments, at cost. As of June 30, 2025, our investment portfolio was made up of approximately 90.0% debt investments and 10.0% equity investments, at cost.

We focus on investing in lower middle market companies (which we generally define as companies with annual earnings before interest, taxes, depreciation and amortization of $3 million to $25 million) in the U.S. that meet certain criteria, including the following: the sustainability of the business’ free cash flow and its ability to grow it over time, adequate assets for loan collateral, experienced management teams with a significant ownership interest in the borrower, reasonable capitalization of the borrower, including an ample equity contribution or cushion based on prevailing enterprise valuation multiples and, to a lesser extent, the potential to realize appreciation and gain liquidity in our equity position, if any. We lend to borrowers that need funds for growth capital or to finance acquisitions or recapitalize or refinance their existing debt facilities. We seek to avoid investing in high-risk, early-stage enterprises. Our targeted portfolio companies are generally considered too small for the larger capital marketplace.

We invest by ourselves or jointly with other funds and/or management of the portfolio company, depending on the opportunity. In July 2012, the SEC granted us an exemptive order (the “Co-Investment Order”) that expanded our ability to co-invest, under certain circumstances, with certain of our affiliates, including Gladstone Investment Corporation, Gladstone Alternative Income Fund (“Gladstone Alternative”), and any future BDC or registered closed-end management investment company that is advised (or sub-advised if it controls the fund) by the Adviser, or any combination of the foregoing, subject to the conditions in the Co-Investment Order. Since 2012, we have opportunistically made co-investments with Gladstone Investment Corporation and Gladstone Alternative pursuant to the Co-Investment Order. We believe the Co-Investment Order has enhanced and will continue to enhance our ability to further our investment objectives and strategies. If we are participating in an investment with one or more co-investors, our investment is likely to be smaller than if we were investing alone.

We are externally managed by the Adviser, an investment adviser registered with the SEC and an affiliate of ours, pursuant to an investment advisory and management agreement. The Adviser manages our investment activities. We have also entered into an administration agreement with Gladstone Administration, LLC (the “Administrator”), an affiliate of ours and the Adviser, whereby we pay separately for administrative services.

Additionally, Gladstone Securities, LLC (“Gladstone Securities”), a privately-held broker-dealer registered with the Financial Industry Regulatory Authority and insured by the Securities Investor Protection Corporation, which is 100% indirectly owned and controlled by Mr. Gladstone, our chairman and chief executive officer, has provided other services, such as investment banking and due diligence services, to certain of our portfolio companies, for which Gladstone Securities receives a fee.

Business

Portfolio and Investment Activity

In general, our investments in debt securities have a term of no more than seven years, accrue interest at variable rates (generally based on one-month Term Secured Overnight Financing Rate (“SOFR”)) and, to a lesser extent, at fixed rates. We seek debt instruments that pay interest monthly or, at a minimum, quarterly, may have a success fee or deferred interest provision and are primarily interest only, with all principal and any accrued but unpaid interest due at maturity. Generally, success fees accrue at a set rate and are contractually due upon a change of control of a portfolio company, typically from an exit or sale. Some debt securities have deferred interest whereby some portion of the interest payment is added to the principal balance so that the interest is paid, together with the principal, at maturity. This form of deferred interest is often called paid-in-kind (“PIK”) interest.

Table of Contents

Typically, our equity investments consist of common stock, preferred stock, limited liability company interests, or warrants to purchase the foregoing. Often, these equity investments occur in connection with our original investment, recapitalizing a business, or refinancing existing debt.

During the nine months ended June 30, 2025, we invested $204.0 million in ten new portfolio companies and extended $66.1 million in investments to existing portfolio companies. In addition, we exited eight portfolio companies during the nine months ended June 30, 2025. We received a total of $328.8 million in combined net proceeds and principal repayments from the aforementioned portfolio company exits, as well as principal repayments by existing portfolio companies, during the nine months ended June 30, 2025. Our overall portfolio consists of 51 portfolio companies as of June 30, 2025 and increased by $6.8 million at cost since September 30, 2024. From our initial public offering in August 2001 through June 30, 2025, we have made 695 different loans to, or investments in, 287 companies for a total of approximately $3.0 billion, before giving effect to principal repayments on investments and divestitures.

During the nine months ended June 30, 2025, the following significant transactions occurred:
