Certain investments are subject to an interest rate floor. For fixed rate loans, a spread above a reference rate is not applicable. For positions with multiple outstanding contracts, the spread for the largest outstanding contract is shown. Listed below are the index rates as of March 31, 2026, which was the last business day of the period on which the applicable index rates were determined. The actual index rate for each loan listed could not be the applicable index rate outstanding as of March 31, 2026, as the loan could have priced or repriced based on an index rate prior to March 31, 2026.

(a) Denotes that all or a portion of the contract was indexed to the Prime rate, which was 6.75% as of March 31, 2026.

(3)The total principal amount is presented for debt investments while the number of shares or units owned is presented for equity investments.

(4)The fair values of investments were valued using significant unobservable inputs, unless noted otherwise. See Note 6. The fair value of loan investments may include the impact of the unfunded commitment being valued below par.

(5)The negative fair value is the result of the capitalized discount on the loan or the unfunded commitment being valued below par. The negative amortized cost is the result of the capitalized discount being greater than the principal amount outstanding on the loan.

(6)The entire commitment was unfunded as of March 31, 2026. As such, no interest is being earned on this investment. The investment could be subject to an unused facility fee.

(7)Investment was on non-accrual status as of March 31, 2026, meaning that the Company has ceased recognizing interest or non-cash dividend income on the investment.

(8)The investment is treated as a non-qualifying asset under Section 55(a) of the Investment Company Act of 1940, as amended (the “1940 Act”).

+ Denotes that all or a portion of the investment collateralizes the JPM Credit Facility (as defined in Note 7).

(1)The majority of the investments bear interest at a rate that is permitted to be determined by reference to the Secured Overnight Financing Rate (“SOFR” or “SF”), Euro Interbank Offered Rate (“EURIBOR” or “E”), Prime (“P”), Sterling Overnight Index Average ("SONIA" or “SN”), Australian Interbank Rate (”AUD” or ”A”) or Canadian Overnight Repo Rate Average (“CORRA” or “CA”) which reset daily, monthly, quarterly, semiannually, or annually. For each, the Company has provided the spread over the applicable index and the weighted average current interest rate in effect as of September 30, 2025. Certain investments are subject to an interest rate floor. For fixed rate loans, a spread above a reference rate is not applicable. For positions with multiple outstanding contracts, the spread for the largest outstanding contract is shown. Listed below are the index rates as of September 30, 2025, which was the last business day of the period on which the applicable index rates were determined. The actual index rate for each loan listed could not be the applicable index rate outstanding as of September 30, 2025, as the loan could have priced or repriced based on an index rate prior to September 30, 2025.

(6)The entire commitment was unfunded as of September 30, 2025. As such, no interest is being earned on this investment. The investment could be subject to an unused facility fee.

(7)Investment was on non-accrual status as of September 30, 2025, meaning that the Company has ceased recognizing interest or non-cash dividend income on the investment.

(8)The investment is treated as a non-qualifying asset under Section 55(a) of the Investment Company Act of 1940, as amended (the “1940 Act”). Under the 1940 Act, the Company cannot acquire any non-qualifying asset unless, at the time the acquisition is made, qualifying assets represent at least 70% of the Company's total assets.

Note 1. Organization

Golub Capital BDC, Inc. (“GBDC” and, collectively with its consolidated subsidiaries, the “Company”) is an externally managed, closed-end, non-diversified management investment company. GBDC has elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). In addition, for U.S. federal income tax purposes, GBDC has elected to be treated as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”).

The Company’s investment strategy is to invest primarily in one stop (a loan that combines characteristics of traditional first lien senior secured loans and second lien or subordinated loans and that are often referred to by other middle-market lenders as unitranche loans) and other senior secured loans of U.S. middle-market companies that are, in most cases, sponsored by private equity firms. The Company also selectively invests in second lien and subordinated (a loan that ranks senior only to a borrower’s equity securities and ranks junior to all of such borrower’s other indebtedness in priority of payment) loans of, and warrants and minority equity securities in, U.S. middle-market companies. The Company has entered into the Fifth Amended and Restated Investment Advisory Agreement effective as of June 3, 2024 (the “Investment Advisory Agreement” or “Post-GBDC 3 Merger Advisory Agreement”) with GC Advisors LLC (the “Investment Adviser”), under which the Investment Adviser manages the day-to-day operations of, and provides investment advisory services to, the Company. Under an administration agreement (the “Administration Agreement”) the Company is provided with certain services by an administrator (the “Administrator”), which is currently Golub Capital LLC.

On September 16, 2019, the Company completed its acquisition of Golub Capital Investment Corporation (“GCIC”), a Maryland corporation (the “GCIC Merger”), pursuant to that certain Agreement and Plan of Merger (as amended, the “GCIC Merger Agreement”), dated as of November 27, 2018, by and among the Company, GCIC, Fifth Ave Subsidiary Inc., a Maryland corporation and wholly owned subsidiary of the Company (“GCIC Merger Sub”), the Investment Adviser, and, for certain limited purposes, the Administrator.

On June 3, 2024, the Company completed its acquisition of Golub Capital BDC 3, Inc. (“GBDC 3”), a Maryland corporation (the “GBDC 3 Merger”), pursuant to that certain Agreement and Plan of Merger (as amended, the “GBDC 3 Merger Agreement”), dated as of January 16, 2024, by and among the Company, GBDC 3, Park Avenue Subsidiary Inc., a Maryland corporation and wholly owned subsidiary of the Company (“GBDC 3 Merger Sub”), the Investment Adviser, and, for certain limited purposes, the Administrator.

Note 2. Significant Accounting Policies and Recent Accounting Updates

Basis of presentation:  The Company is an investment company as defined in the accounting and reporting guidance under Accounting Standards Codification (“ASC”) Topic 946 — Financial Services — Investment Companies (“ASC Topic 946”).

The accompanying unaudited interim consolidated financial statements of the Company and related financial information have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) as established by the Financial Accounting Standards Board (“FASB”) 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, they do not include all of the information and notes required by GAAP for annual financial statements. In the opinion of management, the consolidated financial statements reflect all adjustments and reclassifications consisting solely of normal accruals that are necessary for the fair presentation of financial results as of and for the periods presented. All intercompany balances and transactions have been eliminated. Certain prior period amounts have been reclassified to conform to the current period presentation. The unaudited interim consolidated financial statements and notes thereto should be read in conjunction with the financial statements and notes thereto in the Company’s Form 10-K for the year ended September 30, 2025, as filed with the U.S. Securities and Exchange Commission (the “SEC”).

Fair value of financial instruments: The Company applies fair value to all of its financial instruments in accordance with ASC Topic 820 — Fair Value Measurement (“ASC Topic 820”). ASC Topic 820 defines fair value, establishes a framework used to measure fair value and requires disclosures for fair value measurements. On August 2, 2024, the Company’s board of directors (the “Board”) designated the Investment Adviser as the Company’s valuation designee (“Valuation Designee”) in accordance with Rule 2a-5 under the 1940 Act. As of such date, the Valuation Designee is responsible for determining the fair value of the

TABLE OF CONTENTS

Golub Capital BDC, Inc. and Subsidiaries

Notes to Consolidated Financial Statements (unaudited)

(In thousands, except shares and per share data)

Company’s portfolio investments, subject to oversight of the Board. In accordance with ASC Topic 820, the Valuation Designee has categorized the Company’s financial instruments carried at fair value, based on the priority of the valuation technique, into a three-level fair value hierarchy. Fair value is a market-based measure considered from the perspective of the market participant who holds the financial instrument rather than an entity-specific measure. Therefore, when market assumptions are not readily available, the Investment Adviser’s own assumptions are set to reflect those that management believes market participants would use in pricing the financial instrument at the measurement date.

The availability of observable inputs can vary depending on the financial instrument and is affected by a wide variety of factors, including, for example, the type of product, whether the product is new, whether the product is traded on an active exchange or in the secondary market and the current market conditions. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Valuation Designee in determining fair value is greatest for financial instruments classified as Level 3.

Any changes to the valuation methodology are reviewed by management and the Board to confirm that the changes are appropriate. As markets change, new products develop and the pricing for products becomes more or less transparent, the Valuation Designee will continue to refine its valuation methodologies. See further description of fair value methodology in Note 6.

Use of estimates: The preparation of the unaudited interim consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Assets related to transactions that do not meet ASC Topic 860 requirements for accounting sale treatment are reflected in the Company’s Consolidated Statements of Financial Condition as investments. Those assets are owned by special purpose entities, including BDC Holdings, Funding II, GCIC Holdings, GBDC 3 Holdings, GBDC 3 Funding, 2024 Issuer and, prior to November 18, 2024, GCIC 2018 Issuer, 2018 Issuer and GBDC 3 2021 Issuer, GCIC Funding (prior to April 30, 2025), GBDC 3 2022-2 Issuer (prior to May 19, 2025), and GBDC 3 2022 Issuer (prior to August 21, 2025) that are consolidated in the Company’s consolidated financial statements. The creditors of the special purpose entities have received security interests in such assets and such assets are not intended to be available to the creditors of GBDC (or any affiliate of GBDC).

Cash, cash equivalents and foreign currencies: Cash, cash equivalents and foreign currencies are highly liquid investments with an original maturity of three months or less at the date of acquisition. The Company deposits its cash in financial institutions and, at times, such balances exceed the Federal Deposit Insurance Corporation insurance limits.

Restricted cash, restricted cash equivalents and restricted foreign currencies: Restricted cash, restricted cash equivalents and restricted foreign currencies include amounts that are collected and are held by trustees who have been appointed as custodians of the assets securing certain of the Company’s financing transactions. Restricted cash, restricted cash equivalents and restricted foreign currencies are held by the trustees for payment of interest expense and principal on the outstanding borrowings or reinvestment into new assets.

Foreign currency translation: The Company’s books and records are maintained in U.S. dollars. Any foreign currency amounts are translated into U.S. dollars. Non-U.S. dollar transactions during the period are valued at the prevailing spot rates on the applicable transaction date and the related assets and liabilities are revalued at the prevailing spot rates as of period-end.

Net assets and fair values are presented based on the applicable foreign exchange rates and fluctuations arising from the translation of assets and liabilities are included within the net change in unrealized appreciation (depreciation) on translation of assets and liabilities in foreign currencies on the Consolidated Statements of Operations.

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

Derivative instruments:

The Company follows the guidance in ASC Topic 815 - Derivatives and Hedging (“ASC Topic 815”), when accounting for derivative instruments.

Forward currency contracts: A forward currency contract is an obligation between two parties to purchase or sell a specific currency for an agreed-upon price at a future date. The Company utilized forward currency contracts to economically hedge the currency exposure associated with certain foreign-denominated investments. The use of forward currency contracts does not eliminate fluctuations in the price of the underlying securities the Company owns or intends to acquire but establishes a rate of exchange in advance. Fluctuations in the value of these contracts are measured by the difference in the exchange rates on the contract date and reporting date and are recorded as unrealized appreciation (depreciation) until the contracts are closed. When the contracts are closed, realized gains (losses) are recorded. Realized gains (losses) and unrealized appreciation (depreciation) on the forward currency contracts are included in the Consolidated Statements of Operations. Unrealized appreciation (depreciation) on forward currency contracts is recorded on the Consolidated Statements of Financial Condition as a component of “Net unrealized appreciation on derivatives” or “Net unrealized depreciation on derivatives” by counterparty on a net basis across all derivative instruments, not taking into account collateral posted, which is recorded separately, if applicable.

The primary risks associated with forward currency contracts include failure of the counterparty to meet the terms of the contract and the value of the foreign currency changing unfavorably. These risks can exceed the amounts reflected in the Consolidated Statements of Financial Condition.

Refer to Note 5 for more information regarding the forward currency contracts.

Interest rate swaps: The Company designated interest rate swaps as the hedging instrument in qualifying fair value hedge accounting relationships, and as a result, the change in fair value of the hedging instruments and hedged items are recorded in interest expense and recognized as components of “Interest and other debt financing expenses” in the Company’s Consolidated Statements of Operations. The fair value of the interest rate swaps is recorded on the Consolidated Statements of Financial Condition as a component of “Net unrealized appreciation on derivatives” or “Net unrealized depreciation on derivatives” by counterparty on a net basis across all derivative instruments, not taking into account collateral posted which is recorded separately, if applicable.

Refer to Note 5 for more information regarding the interest rate swaps.

Revenue recognition:

Investments and related investment income: Interest income is accrued based upon the outstanding principal amount and contractual interest terms of debt investments.

Original issue discount, market discount or premium and certain loan origination or amendment fees that are deemed to be an adjustment to yield (“Loan Origination Fees”) are capitalized and the Company accretes or amortizes such amounts over the life of the loan as interest income (“Discount Amortization”). For the three and six months ended March 31, 2026, the Company received Loan Origination Fees that were capitalized of $1,842 and $5,363, respectively. For the three and six months ended March 31, 2025, the Company received Loan Origination Fees that were capitalized of $4,781 and $17,540, respectively. For the three and six months ended March 31, 2026, interest income included $5,740 and $12,284, respectively, of Discount Amortization. For the three and six months ended March 31, 2025, interest income included $6,700 and $12,955, respectively, of Discount Amortization.

For investments with contractual payment-in-kind (“PIK”) interest, which represents contractual interest accrued and added to the principal balance that generally becomes due at maturity, the Company will not accrue PIK interest if the portfolio company valuation indicates that the PIK interest is not collectible. For the three and six months ended March 31, 2026, investment income included $17,132 and $31,651, respectively, of PIK interest and the Company capitalized PIK interest of $18,561 and $32,718, respectively, into the principal balance of certain debt investments. For the three and six months ended March 31, 2025, investment income included $14,045 and $25,061, respectively, of PIK interest and the Company capitalized PIK interest of $14,710 and $27,921, respectively, into the principal balance of certain debt investments.

In addition, the Company generates revenue in the form of amendment, structuring or due diligence fees, fees for providing managerial assistance, consulting fees, administrative agent fees, and prepayment premiums on loans. The Company records these fees that are not deemed to be an adjustment to yield as fee income when earned. For the three and six months ended March 31, 2026, fee income included $196 and $761 from non-recurring prepayment premiums, respectively. For the three and six months ended March 31, 2025, fee income included $1,203 and $1,297 from non-recurring prepayment premiums, respectively.

For the three and six months ended March 31, 2026, the Company received interest and fee income in cash, which excludes capitalized loan origination fees, in the amounts of $169,873 and $347,269, respectively. For the three and six months ended March 31, 2025, the Company received interest and fee income in cash, which excludes capitalized loan origination fees, in the amounts of $197,416 and $398,783, respectively.

Dividend income on equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. The Company has certain preferred equity securities in the portfolio that contain a PIK dividend provision that are accrued and recorded as income at the contractual rates, if deemed collectible. The accrued PIK and non-cash dividends are capitalized to the cost basis of the preferred equity security and are generally collected when redeemed by the issuer.

For the three and six months ended March 31, 2026, the Company recognized PIK and non-cash dividend income of $6,158 and $13,192, respectively, which were capitalized into the cost basis of certain preferred equity investments. For the three and six months ended March 31, 2025, the Company recognized PIK and non-cash dividend income of $7,807 and $15,071, respectively, which were capitalized into the cost basis of certain preferred equity investments. For both the three and six months ended March 31, 2026 the Company received $235 of cash payments of accrued and capitalized preferred dividends. For the three and six months ended March 31, 2025 the Company received $1,725 and $3,549, respectively, of cash payments of accrued and capitalized preferred dividends.

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

For the three and six months ended March 31, 2026, the Company recorded dividend income received in cash of $202 and $787, respectively, and return of capital distributions received in cash of $410 and $502, respectively. For the three and six months ended March 31, 2025, the Company recorded dividend income received in cash of $70 and $1,293, respectively, and return of capital distributions received in cash of $109 and $344, respectively.

Investment transactions are accounted for on a trade-date basis. Realized gains or losses on investments are measured by the difference between the net proceeds from the disposition and the amortized cost basis of investment, without regard to unrealized gains or losses previously recognized. The Company reports current period changes in fair value of investments that are measured at fair value as a component of the “Net change in unrealized appreciation (depreciation) on investment transactions” in the Consolidated Statements of Operations.

Non-accrual investments: A loan can be left on accrual status while the Company is pursuing repayment of the loan. Management reviews all loans that become 90 days or more past due on principal and interest, or when there is reasonable doubt that principal or interest will be collected, for possible placement on non-accrual status. When a loan is placed on non-accrual status, unpaid interest credited to income is reversed. Additionally, any capitalized Loan Origination Fees are no longer accreted to interest income as of the date the loan is placed on non-accrual status. Interest payments received on non-accrual loans are recognized as income or applied to principal depending upon management’s judgment. Non-accrual loans are restored to accrual status when past due principal and interest is paid and, in management’s judgment, payments are likely to remain current. The total fair value of non-accrual loans was $77,727 and $27,321 as of March 31, 2026 and September 30, 2025, respectively.

Management reviews all preferred equity securities accruing contractual PIK dividend income to determine if there is reasonable doubt that amortized cost or capitalized PIK and non-cash dividend income will be collected for possible placement on non-accrual status. When a preferred equity security is placed on non-accrual status, the contractual PIK dividend provision is no longer accrued to dividend income as of the date the preferred equity security is placed on non-accrual status. As of March 31, 2026, there were four preferred equity securities on non-accrual status with a fair value of $40,783. As of September 30, 2025, there was one preferred equity security on non-accrual status with a fair value of $0.

Asset Acquisition: Pursuant to the GCIC Merger Agreement, the GCIC Merger Sub was first merged with and into GCIC, with GCIC as the surviving company, and, immediately following this initial merger, GCIC was then merged with and into the Company, with the Company as the surviving company. Pursuant to the GBDC 3 Merger Agreement, the GBDC 3 Merger Sub was first merged with and into GBDC 3, with GBDC 3 as the surviving company and, immediately following this initial merger, GBDC 3 was then merged with and into the Company, with the Company as the surviving company. The GCIC Merger and the GBDC 3 Merger were accounted for under the asset acquisition method of accounting in accordance with ASC 805 — Business Combinations — Related Issues (“ASC Topic 805”), also referred to as “asset acquisition.” Under the asset acquisition method of accounting, acquiring assets in groups not only requires ascertaining the cost of the asset (or net assets), but also allocating that cost to the individual assets (or individual assets and liabilities) that make up the group. Per ASC Topic 805, assets are recognized based on their cost to the acquiring entity, which generally includes transaction costs of the asset acquisition, and no gain or loss is recognized unless the fair value of non-cash assets given as consideration differs from the assets carrying amounts on the acquiring entity’s books.

The cost of the group of assets acquired in an asset acquisition is allocated to the individual assets acquired or liabilities assumed based on the relative fair values of net identifiable assets acquired other than “non-qualifying” assets (for example cash) and does not give rise to goodwill. To the extent that the consideration paid to GCIC or GBDC 3’s stockholders exceeded the relative fair values of the net identifiable assets of GCIC or GBDC 3 acquired other than “non-qualifying” assets, any such premium paid by the Company was further allocated to the cost of the

GCIC or GBDC 3 assets acquired by the Company pro-rata to their relative fair value, other than “non-qualifying” assets. As both GCIC and GBDC 3 did not have any “qualifying” assets at the time of acquisition, the premium was allocated to “non-qualifying” assets, which are GCIC and GBDC 3’s investments in loans and equity securities, including its investment in GCIC SLF. Immediately following the acquisitions of GCIC and GBDC 3, the Company recorded its assets at their respective fair values and, as a result, the purchase premium allocated to the cost basis of the GCIC and GBDC 3 assets acquired were immediately recognized as unrealized depreciation on the Company's Consolidated Statement of Operations. The purchase premium allocated to investments in loan securities will amortize over the life of the loans through interest income, with a corresponding reversal of the unrealized depreciation on the loans acquired from GCIC and GBDC 3 through their ultimate disposition. Amortization expense of purchase premium for the three and six months ended March 31, 2026 was $2,520 and $5,688, respectively. Amortization expense of purchase premium for the three and six months ended March 31, 2025 was $4,592 and $10,278, respectively. The purchase premium allocated to investments in equity securities will not amortize over the life of the equity securities through interest income and, assuming no subsequent change to the fair value of the equity securities acquired from GCIC or GBDC 3 and disposition of such equity securities at fair value, the Company will recognize a realized loss with a corresponding reversal of the unrealized depreciation upon disposition of the equity securities acquired from GCIC or GBDC 3.

Income taxes: The Company has elected to be treated as a RIC under Subchapter M of the Code and operates in a manner so as to qualify for the tax treatment applicable to RICs. In order to qualify and be subject to tax as a RIC, among other things, the Company is required to meet certain source of income and asset diversification requirements and timely distribute dividends for U.S. federal income tax purposes to its stockholders of an amount generally at least equal to 90% of investment company taxable income, as defined by the Code and determined without regard to any deduction for dividends paid, for each tax year. The Company has made, and intends to continue to make, the requisite distributions to its stockholders, which will generally relieve the Company from U.S. federal income taxes with respect to all income distributed to its stockholders.

Depending on the level of taxable income earned in a tax year, the Company can determine to retain taxable income in excess of current year dividend distributions and distribute such taxable income in the next tax year. The Company could then be required to incur a 4% excise tax on such income. To the extent that the Company determines that its estimated current year annual taxable income, determined on a calendar year basis, could exceed estimated current calendar year dividend distributions, the Company accrues excise tax, if any, on estimated excess taxable income as taxable income is earned. For the three and six months ended March 31, 2026, no U.S. federal excise tax was recorded. For the three months ended March 31, 2025, the Company did not record any U.S. federal excise tax expense. For the six months ended March 31, 2025, the Company recorded a reversal of the accrual for U.S. federal excise tax expense of $475.

The Company accounts for income taxes in conformity with ASC Topic 740 — Income Taxes (“ASC Topic 740”). ASC Topic 740 provides guidelines for how uncertain tax positions should be recognized, measured, presented and disclosed in the consolidated financial statements. ASC Topic 740 requires the evaluation of tax positions taken in the course of preparing the Company’s tax returns to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax expense or tax benefit in the current year. It is the Company’s policy to recognize accrued interest and penalties related to uncertain tax benefits in income tax expense. There were no material unrecognized tax benefits or unrecognized tax liabilities related to uncertain income tax positions through March 31, 2026. The Company’s tax returns for the 2022 through 2024 tax years remain subject to examination by U.S. federal and most state tax authorities.

Certain of the Company's consolidated subsidiaries are subject to U.S. federal and state corporate-level income taxes. Income tax expense, if any, is included under the income category for which it applies in the Consolidated Statements of Operations. For the three and six months ended March 31, 2026 and 2025, the Company did not record any U.S. income tax expense.

Dividends and distributions: Dividends and distributions to common stockholders are recorded on the ex-dividend date. The amount to be paid out as a dividend or distribution is determined by the Board each quarter and is generally based upon the earnings estimated by management. Net realized capital gains, if any, are distributed at least annually, although the Company can retain such capital gains for investment in its discretion.

The Company has adopted a dividend reinvestment plan (“DRIP”) that provides for reinvestment of any distributions the Company declares in cash on behalf of its stockholders, unless a stockholder elects to receive cash. As a result, if the Board authorizes and the Company declares a cash distribution, then stockholders who participate in the DRIP will have their cash distribution reinvested in additional shares of the Company’s common stock, rather than receiving the cash distribution. The Company expects to use newly issued shares under the guidelines of the DRIP if the Company’s shares are trading at a premium to net asset value. The Company can purchase shares in the open market in connection with the obligations under the plan, and in particular, if the Company’s shares are trading at a significant discount to net asset value (“NAV”) and the Company is otherwise permitted under applicable law to purchase such shares, the Company intends to purchase shares in the open market in connection with any obligations under the DRIP.

In the event the market price per share of the Company’s common stock on the date of a distribution exceeds the most recently computed NAV per share of the common stock, the Company will issue shares of common stock to participants in the DRIP at the greater of the most recently computed NAV per share of common stock or 95% of the current market price per share of common stock (or such lesser discount to the current market price per share that still exceeds the most recently computed NAV per share of common stock).

Share repurchase plan: The Company has a share repurchase program (the “Program”) which allows the Company to repurchase the Company’s outstanding common stock on the open market at prices below the Company’s NAV as reported in its most recently published consolidated financial statements. The Board re-approved the Program in August 2025 and the Program is implemented at the discretion of management. Shares can be purchased from time to time at prevailing market prices, through open market transactions, including block transactions. The Program permits repurchases up to $150,000 of the Company's common stock. Refer to Note 11 for more information on the share repurchases under the Program.

Equity Distribution Agreement: On October 6, 2023, the Company entered into an equity distribution agreement, which was most recently amended on May 16, 2025 (the “2023 Equity Distribution Agreement”), by and among the Company, the Investment Adviser, the Administrator, and Keefe, Bruyette & Woods, Inc. and Regions Securities LLC (the “Placement Agents”), in connection with the sale by the Company of shares of its common stock, having an aggregate offering price of up to $288,043, in an “at the market offering,” in amounts and at times to be determined by the Company. Through March 31, 2026, the Company has issued 2,408,940 of shares of its common stock for net proceeds to the Company of $38,043 under the 2023 Equity Distribution Agreement. Actual sales, if any, will depend on a variety of factors to be determined by the Company from time to time, including, among others, market conditions and the market price of the Company’s common stock. The 2023 Equity Distribution Agreement provides that the Company can offer and sell shares of its common stock from time to time through, or to, the Placement Agents. Sales of the shares can be made in negotiated transactions or transactions that are deemed to be “at the market,” as defined in Rule 415 under the Securities Act of 1933, as amended, including sales made directly on The Nasdaq Global Select Market or any similar securities exchange or sales made to or through a market maker other than on a securities exchange, at prices related to the prevailing market prices or at negotiated prices. Pursuant to the terms of the 2023 Equity Distribution Agreement, the Placement Agents receive a commission from the Company of up to 1.50% of the gross sales price of any shares sold through the Placement Agents under the 2023 Equity Distribution Agreement. Offering costs for the 2023 Equity Distribution Agreement are charged against the proceeds from equity offerings when proceeds are received. During the three and six months ended March 31, 2026, the Company did not issue any shares of common stock under the 2023 Equity Distribution Agreement. During the three and six months ended March 31, 2025, the Company issued 2,408,940 shares of common stock under the 2023 Equity Distribution Agreement.

Deferred debt issuance costs: Deferred debt issuance costs represent fees and other direct incremental costs incurred in connection with the Company’s borrowings. As of March 31, 2026 and September 30, 2025, the Company had deferred debt issuance costs of $21,427 and $26,005, respectively.

These amounts are amortized and included in “Interest expense and other debt financing expenses” in the Consolidated Statements of Operations over the estimated average life of the borrowings. Amortization expense for deferred debt issuance costs for the three and six months ended March 31, 2026 was $2,572 and $5,179, respectively. Amortization expense for deferred debt issuance costs for the three and six months ended March 31, 2025 was $2,479 and $5,124, respectively.

Deferred offering costs: Deferred offering costs consist of fees paid in relation to legal, accounting, regulatory and printing work completed in preparation of equity offerings. Deferred offering costs are charged against the proceeds from equity offerings when received. These amounts are included in “Other assets” on the Consolidated Statements of Financial Condition.

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

The Company operates through a single operating and reporting segment with an investment objective to generate both current income and, to a lesser extent, capital appreciation through debt and equity investments. The chief operating decision maker (the “CODM”) is comprised of the senior executive committee that, as of March 31, 2026, includes the Company’s chief executive officer, chief financial officer and chief operating officer and assesses the performance and makes operating decisions of the Company on a consolidated basis primarily based on the Company’s net increase (decrease) in net assets resulting from operations (“net income”). In addition to numerous other factors and metrics, the CODM utilizes net income as a key metric in evaluating the Company’s distribution policy. Performance metrics are provided to the CODM on a quarterly basis and are utilized to evaluate performance generated from segment net assets. As the Company’s operations comprise of a single reporting segment, the segment assets are reflected on the accompanying consolidated statement of financial condition as “total assets” and the significant segment expenses are listed on the accompanying consolidated statement of operations.

Recent Accounting Updates: In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40). ASU No. 2024-03 requires disaggregated disclosure of certain costs and expenses, including purchase of inventory, employee compensation, depreciation, amortization and depletion, within relevant income statement captions. ASU 2024-03 is effective for annual years beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption and retrospective application are permitted. The Company is currently evaluating the impact of adopting ASU No. 2024-03.

Note 3. Related Party Transactions

Investment Advisory Agreement: Under the Investment Advisory Agreement, the Investment Adviser manages the day-to-day operations of, and provides investment advisory services to, GBDC. The Board most recently re-approved the Investment Advisory Agreement in May 2026. The Investment Adviser is a registered investment adviser with the U.S. Securities and Exchange Commission (the “SEC”). The Investment Adviser receives fees for providing services, consisting of two components, a base management fee and an Incentive Fee (as defined below).

The base management fee is calculated at an annual rate equal to 1.0% (or 1.375% for periods ending on or before June 30, 2023) of the fair value of the average adjusted gross assets of the Company at the end of the two most recently completed calendar quarters (including assets purchased with borrowed funds and securitization-related assets, leverage, unrealized depreciation or appreciation on derivative instruments and cash collateral on deposit for such derivative instruments with custodian but adjusted to exclude cash, cash equivalents, restricted cash and restricted cash equivalents, and foreign currencies so that investors do not pay the base management fee on such assets) and is payable quarterly in arrears. Additionally, the Investment Adviser voluntarily excludes any assets funded with secured borrowing proceeds from the base management fee calculation. The base management fee is adjusted, based on the actual number of days elapsed relative to the total number of days in such calendar quarter, for any share issuances or repurchases during such calendar quarter. For purposes of the Investment Advisory Agreement, cash equivalents mean U.S. government securities and commercial paper instruments maturing within 270 days of purchase (which is different than the GAAP definition, which defines cash equivalents as U.S. government securities and commercial paper instruments maturing within 90 days of purchase). To the extent that the Investment Adviser or any of its affiliates provides investment advisory, collateral management or other similar services to a subsidiary of the Company, the base management fee will be reduced by an amount equal to the product of (1) the total fees paid to the Investment Adviser by such subsidiary for such services and (2) the percentage of such subsidiary’s total equity, including membership interests and any class of notes not exclusively held by one or more third parties, that is owned, directly or indirectly, by the Company.

The Investment Adviser served as collateral manager under the 2018 Collateral Management Agreement (as described in Note 7), the GCIC 2018 Collateral Management Agreement (as described in Note 7), the 2021 Collateral Management Agreement (as described in Note 7), the 2022 Collateral Management Agreement (as described in Note 7), and the 2022-2 Collateral Management Agreement (as described in Note 7), prior to their redemption, and serves as the collateral manager under the 2024 Collateral Management Agreement (as described in Note 7). Fees payable to the Investment Adviser for providing these services are offset against the base management fee payable by the Company under the Investment Advisory Agreement.

The base management fee incurred for the three and six months ended March 31, 2026 was $21,035 and $43,150, respectively. The base management fee incurred for the three and six months ended March 31, 2025 was $21,714 and $43,295, respectively.

The Company has structured the calculation of the Incentive Fee to include a fee limitation such that an Incentive Fee for any quarter can only be paid to the Investment Adviser if, after such payment, the cumulative Incentive Fees paid to the Investment Adviser, calculated on a per share basis, since April 13, 2010, the effective date of the Company’s election to become a BDC, would be less than or equal to 15.0% of the Company’s Cumulative Pre-Incentive Fee Net Income Per Share (as defined below).

The Company accomplishes this limitation by subjecting each quarterly Incentive Fee payable under the Income and Capital Gain Incentive Fee Calculation (as defined below) to a cap (the “Incentive Fee Cap”). Under the Investment Advisory Agreement, the Incentive Fee Cap in any quarter is equal to the difference between (a) 15.0% of Cumulative Pre-Incentive Fee Net Income Per Share (as defined below) and (b) Cumulative Incentive Fees Paid Per Share (as defined below). To the extent the Incentive Fee Cap is zero or a negative value in any quarter, no Incentive Fee would be payable in that quarter. If, for any relevant period, the Incentive Fee Cap calculation results in the Company paying less than the amount of the Incentive Fee calculated above, then the difference between the Incentive Fee and the Incentive Fee Cap will not be paid by GBDC and will not be received by the Investment Adviser as an Incentive Fee either at the end of such relevant period or at the end of any future period. “Cumulative Pre-Incentive Fee Net Income Per Share” equals the sum of “Pre-Incentive Fee Net Income Per Share” (as defined below) for each quarterly period since April 13, 2010. “Pre-Incentive Fee Net Income Per Share” equals the sum of (i) Pre-Incentive Fee Net Investment Income (as defined below) and (ii) Adjusted Capital Returns for the applicable period, divided by (b) the weighted average number of shares of GBDC common stock outstanding during such period. “Adjusted Capital Returns” for any period is the sum of the realized aggregate capital gains, realized aggregate capital losses, aggregate unrealized capital depreciation and aggregate unrealized capital appreciation for such period; provided that the calculation of realized aggregate capital gains, realized aggregate capital losses, aggregate unrealized capital depreciation and aggregate unrealized capital appreciation shall not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation resulting solely from the asset acquisition for any premium or discount paid for the acquisition of assets in a merger. “Cumulative Incentive Fees Paid Per Share” is equal to the sum of Incentive Fees Paid Per Share since April 13, 2010. “Incentive Fees Paid Per Share” for any period is equal to the Incentive Fees accrued and/or payable to the Company for such period, divided by the weighted average number of shares of common stock of GBDC during such period.

“Pre-Incentive Fee Net Investment Income” means interest income, dividend income and any other income (including any other fees such as commitment, origination, structuring, diligence and consulting fees or other fees that the Company receives from portfolio companies but excluding fees for providing managerial assistance) accrued during the calendar quarter, minus operating expenses for the calendar quarter (including the base management fee, taxes, any expenses payable under the Investment Advisory Agreement and the Administration Agreement, any expenses of securitizations and any interest expense and dividends paid on any outstanding preferred stock, but excluding the Incentive Fee). Pre-Incentive Fee Net Investment Income includes, in the case of investments with a deferred interest feature such as market discount, debt instruments with PIK interest, preferred stock with PIK dividends and zero coupon securities, accrued income that the Company has not yet received in cash.

Incentive Fees are calculated and payable quarterly in arrears (or, upon termination of the Investment Advisory Agreement, as of the termination date).

The income and capital gains incentive fee calculation (the “Income and Capital Gain Incentive Fee Calculation”) has two parts, the income component (the “Income Incentive Fee”) and the capital gains component (the “Capital Gain Incentive Fee” and, together with the Income Incentive Fee, the “Incentive Fee”). The Income Incentive Fee is calculated quarterly in arrears based on the Company’s Pre-Incentive Fee Net Investment Income for the immediately preceding calendar quarter.

For the three and six months ended March 31, 2026, the Income Incentive Fee incurred was $15,542 and $32,999, respectively. For the three and six months ended March 31, 2025, the Income Incentive Fee incurred was $18,247 and $36,305, respectively.

The Investment Advisory Agreement excludes the impact of asset acquisition resulting from a merger, including each of the GCIC Merger and GBDC 3 Merger, from the calculation of income subject to the Income Incentive Fee and the calculation of the Incentive Fee Cap. As a result, under the Investment Advisory Agreement, Pre-Incentive Fee Net Investment Income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation or any amortization or accretion of any purchase premium or discount to interest income solely from the asset acquisition for any premium or discount paid for the acquisition of assets in a merger, such as the premium to net asset value paid for the shares of GCIC and GBDC 3 common stock in the GCIC Merger and GBDC 3 Merger. Because of the structure of the Income Incentive Fee, it is possible that an Incentive Fee is calculated under this formula with respect to a period in which the Company has incurred a loss. For example, if the Company receives Pre-Incentive Fee Net Investment Income in excess of the hurdle rate (as defined below) for a calendar quarter, the Income Incentive Fee will result in a positive value and an Incentive Fee will be paid even if the Company has incurred a loss in such period due to realized and/or unrealized capital losses unless the payment of such Incentive Fee would cause the Company to pay Incentive Fees on a cumulative basis that exceed the Incentive Fee Cap.

Pre-Incentive Fee Net Investment Income, expressed as a rate of return on the value of the Company’s net assets (defined as total assets less indebtedness and before taking into account any Incentive Fees payable during the period) at the end of the immediately preceding calendar quarter, is compared to a fixed “hurdle rate” of 2.0% quarterly.

If market interest rates rise, it is possible that the Company will be able to invest funds in debt instruments that provide for a higher return, which would increase Pre-Incentive Fee Net Investment Income and make it easier for the Investment Adviser to surpass the fixed hurdle rate and receive an Incentive Fee based on such net investment income.

The Company’s Pre-Incentive Fee Net Investment Income used to calculate this part of the Incentive Fee is also included in the amount of the Company’s total assets (excluding cash and cash equivalents but including assets purchased with borrowed funds and securitization-related assets, unrealized depreciation or appreciation on derivative instruments and cash collateral on deposit with custodian) used to calculate the base management fee annual rate.

The Company calculated the Income Incentive Fee with respect to its Pre-Incentive Fee Net Investment Income quarterly, in arrears, as follows:

•Zero in any calendar quarter in which the Pre-Incentive Fee Net Investment Income does not exceed the hurdle rate;

•100% of the Company’s 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 the percentage at which amounts payable to the Adviser equals 15.0% of the Company's Pre-Incentive Fee Net Investment Income as if a hurdle rate did not apply. This portion of the Company’s Pre-Incentive Fee Net Investment Income is referred to as the “catch-up” provision. The catch-up is meant to provide the Investment Adviser with 15.0% of the Pre-Incentive Fee Net Investment Income as if a hurdle rate did not apply; and

•15.0% of the amount of the Company’s Pre-Incentive Fee Net Investment Income, if any, that exceeds the catch-up provision in any calendar quarter.

The Capital Gain Incentive Fee equals (a) 15.0% of the Company’s Capital Gain Incentive Fee Base (as defined below), if any, calculated in arrears as of the end of each calendar year (or upon termination of the Investment Advisory Agreement, as of the termination date), which commenced with the calendar year ending

December 31, 2010, less (b) the aggregate amount of any previously paid Capital Gain Incentive Fees. The Company’s “Capital Gain Incentive Fee Base” equals (1) the sum of (A) realized capital gains, if any, on a cumulative positive basis from the date the Company elected to become a BDC through the end of each calendar year, (B) all realized capital losses on a cumulative basis and (C) all unrealized capital depreciation on a cumulative basis less (2) all unamortized deferred debt issuance costs, if and to the extent such costs exceed all unrealized capital appreciation on a cumulative basis.

•The cumulative aggregate realized capital losses are calculated as the sum of the amounts by which (a) the net sales price of each investment in the Company’s portfolio when sold is less than (b) the accreted or amortized cost basis of such investment.

•The cumulative aggregate realized capital gains are calculated as the sum of the differences, if positive, between (a) the net sales price of each investment in the Company’s portfolio when sold and (b) the accreted or amortized cost basis of such investment.

•The aggregate unrealized capital depreciation is calculated as the sum of the differences, if negative, between (a) the valuation of each investment in the Company’s portfolio as of the applicable Capital Gain Incentive Fee calculation date and (b) the accreted or amortized cost basis of such investment.

Realized capital gains and losses include gains and losses on investments, foreign currencies, including gains and losses on borrowings in foreign currencies, derivative contracts and any income tax related to cumulative aggregate realized gains and losses.

For the three and six months ended March 31, 2026 and 2025, the Company did not accrue a Capital Gain Incentive Fee. As of March 31, 2026 and September 30, 2025, there was no Capital Gain Incentive Fee payable as calculated under the Investment Advisory Agreement as described above. Any payment due for a Capital Gain Incentive Fee under the terms of the Investment Advisory Agreement is calculated in arrears at the end of each calendar year.

In accordance with GAAP, the Company also is required to include the aggregate unrealized capital appreciation on investments in the calculation and accrue a capital gain incentive fee on a quarterly basis as if such unrealized capital appreciation were realized, even though such unrealized capital appreciation is not permitted to be considered in calculating the fee actually payable under the Investment Advisory Agreement, as applicable. If the Capital Gain Incentive Fee Base, adjusted as required by GAAP to include unrealized capital appreciation, is positive at the end of a period, then GAAP requires the Company to accrue a capital gain incentive fee equal to 15% of such amount, less the aggregate amount of the actual Capital Gain Incentive Fees paid and capital gain incentive fees accrued under GAAP in all prior periods. If such amount is negative, then there is no accrual for such period. The resulting accrual under GAAP in a given period results in additional expense if such cumulative amount is greater than in the prior period or a reversal of previously recorded expense if such cumulative amount is less than in the prior period. There can be no assurance that such unrealized capital appreciation will be realized in the future. For the three and six months ended March 31, 2026 and 2025, the Company did not accrue a capital gain incentive fee under GAAP. Changes in the accrual for the capital gain incentive fee under GAAP are included in “Incentive fee” in the Consolidated Statements of Operations. As of March 31, 2026 and September 30, 2025, there was no cumulative accrual of capital gain incentive fees under GAAP included in “Accounts payable and other liabilities” on the Consolidated Statements of Financial Condition.

Administration Agreement: Under the Administration Agreement, the Administrator furnishes the Company with office facilities and equipment, provides the Company with clerical, bookkeeping and record keeping services at such facilities and provides the Company with other administrative services as the Administrator, subject to review by the Board, determines necessary to conduct the Company’s day-to-day operations. The Company reimburses the Administrator the allocable portion of overhead and other expenses incurred by it in performing its obligations under the Administration Agreement, including rent, fees and expenses associated with performing compliance functions and the Company’s allocable portion of the cost of its chief financial officer and chief compliance officer and their respective staffs. The Board reviews such expenses to determine that these expenses, including any allocation of expenses among the Company and other entities for which the Administrator provides similar services, are reasonable and comparable to administrative services charged by unaffiliated third-party asset managers. Under the Administration Agreement, the Administrator also provides, on the Company’s behalf, managerial assistance to those portfolio companies to which the Company is required to provide such assistance and will be paid an additional amount based on the cost of the services provided, which amount shall not exceed the amount the Company receives from such portfolio companies.

Interest Rate Swaps

In connection with the 2028 Notes and 2029 Notes (each as defined in Note 7), the Company entered into interest rate swap agreements to more closely align the interest rate of such liability with its investment portfolio, which consists primarily of floating rate loans. The Company designated these interest rate swaps and the 2028 and 2029 Notes as a qualifying fair value hedge accounting relationship. See Note 7 for more information on the 2028 and 2029 Notes. As of March 31, 2026, the counterparties to the Company’s interest rate swap agreements were SMBC Capital Markets, Inc. and Macquarie Bank Limited. The outstanding interest rate swaps as of March 31, 2026 and September 30, 2025 were as follows:

As a result of the Company’s designation as a hedging instrument in a qualifying fair value hedge accounting relationship, the Company is required to fair value the hedging instrument and the related hedged item, with the changes in the fair value of each being recorded in interest and other debt financing expenses. The net unrealized loss related to the fair value hedge was $158 and $170, respectively, for the three and six months ended March 31, 2026. The net unrealized loss related to the fair value hedge was $35 and $4,696, respectively, for the three and six months ended March 31, 2025. The net unrealized gain/(loss) related to the fair value hedge is included in “Interest

Offsetting Derivatives

In order to better define its contractual rights and to secure rights that will help the Company mitigate its counterparty risk, the Company has entered into an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) with each of its derivative counterparties, Macquarie Bank Limited (“Macquarie”) and SMBC Capital Markets, Inc. (“SMBC” and, together with Macquarie, the “Counterparties” and each a “Counterparty”). Each ISDA Master Agreement is a bilateral agreement between the Company and each Counterparty that governs over the counter (“OTC”) derivatives, including forward currency contracts and interest rate swaps, and contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. The provisions of each ISDA Master Agreements with each of the Counterparties permits a single net payment in the event of a default (close-out netting) or similar event, including the bankruptcy or insolvency of the counterparty.

For financial reporting purposes, cash collateral that has been pledged to cover obligations of the Company and cash collateral received from either Counterparty, if any, is included in the Consolidated Statements of Financial Condition as “Other assets” or “Accounts payable and other liabilities”. As of March 31, 2026 and September 30, 2025, there was $0 and $4,890, respectively, of collateral pledged for derivatives which is included in other assets on the Consolidated Statements of Financial Condition. The Company minimizes counterparty credit risk by only entering into agreements with counterparties that it believes to be of good standing and by monitoring the financial stability of those counterparties.

The following table is intended to provide additional information about the effect of the offsetting derivative contracts on the consolidated financial statements of the Company including: the location of those fair values on the Consolidated Statements of Financial Condition and the Company’s gross and net amount of assets and liabilities available for offset under netting arrangements as well as any related collateral received or pledged by the Company as of March 31, 2026 and September 30, 2025:

Exclusion of the Investment Adviser from Commodity Pool Operator Definition

Engaging in commodity interest transactions such as swap transactions or futures contracts for the Company could cause the Investment Adviser to fall within the definition of “commodity pool operator” under the Commodity Exchange Act (the “CEA”) and related Commodity Futures Trading Commission (the “CFTC”) regulations. The Investment Adviser has claimed an exclusion from the definition of the term “commodity pool operator” under the CEA and the CFTC regulations in connection with its management of the Company and, therefore, is not subject to CFTC registration or regulation under the CEA as a commodity pool operator with respect to its management of the Company.

Note 6. Fair Value Measurements

The Company follows ASC Topic 820 for measuring fair value. Fair value is the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters, or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation models involve some level of estimation and judgment, the degree of which is dependent on the price transparency for the assets or liabilities or market and the assets’ or liabilities’ complexity. Effective August 2, 2024, the Board designated the Investment Adviser as the Company’s Valuation Designee in accordance with Rule 2a-5 under the 1940 Act. The Company’s fair value analysis, currently undertaken by the Valuation Designee, includes an analysis of the value of any unfunded loan commitments. Assets and liabilities are categorized for disclosure purposes based upon the level of judgment associated with the inputs used to measure their value. The valuation hierarchical levels are based upon the transparency of the inputs to the valuation of the asset or liability as of the measurement date. The three levels are defined as follows:

TABLE OF CONTENTS

Golub Capital BDC, Inc. and Subsidiaries

Notes to Consolidated Financial Statements (unaudited)

(In thousands, except shares and per share data)

Level 1:     Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2:     Inputs include quoted prices for similar assets or liabilities in active markets and inputs that are observable for the assets or liabilities, either directly or indirectly, for substantially the full term of the assets or liabilities.

Level 3: Inputs include significant unobservable inputs for the assets or liabilities and include situations where there is little, if any, market activity for the assets or liabilities. The inputs into the determination of fair value are based upon the best information available and require significant management judgment or estimation.

In certain cases, the inputs used to measure fair value fall into different levels of the fair value hierarchy. In such cases, an asset’s or a liability’s categorization within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Currently, the Valuation Designee assesses the levels of assets and liabilities at each measurement date, and transfers between levels are recognized on the actual date of the event or change in circumstances that caused the transfers. There were no transfers among Level 1, 2 and 3 of the fair value hierarchy for assets and liabilities during the six months ended March 31, 2026 and 2025. The following section describes the valuation techniques used to measure different assets and liabilities at fair value and includes the level within the fair value hierarchy in which the assets and liabilities are categorized.

Investments

Level 1 investments are valued using quoted market prices. Level 2 investments are valued using market consensus prices that are corroborated by observable market data and quoted market prices for similar assets and liabilities. Level 3 investments are valued at fair value as determined in good faith by the Valuation Designee, based on input of the Valuation Designee’s personnel and independent valuation firms that have been engaged at the direction of the Valuation Designee to assist in the valuation of each portfolio investment without a readily available market quotation. For periods ending on or before December 31, 2025, at least every other quarter, the valuation for each portfolio investment prepared by the professionals of the Valuation Designee responsible for the valuation function, based on the fair value methodology in accordance with ASC Topic 820 described below (subject to a de minimis threshold) was reviewed by an independent valuation firm. This valuation process was conducted at the end of each fiscal quarter, with each portfolio investment being reviewed at least every other quarter (subject to a de-minimis threshold) with approximately 50% (based on the fair value of portfolio company investments) of the Company’s valuations of debt and equity investments without readily available market quotations subject to review by an independent valuation firm. For periods beginning after December 31, 2025, the valuation process is conducted on a monthly basis and this monthly valuation process begins with each portfolio investment being initially valued, based on the fair value methodology in accordance with ASC Topic 820 described below, either by (i) professionals of the Valuation Designee responsible for the valuation function or (ii) investment valuation firms that have been engaged to support the valuation of portfolio investments. The valuation for each portfolio investment, or approximately 100% (based on the fair value of portfolio company investments) of the Company’s debt and equity investments without readily available market quotations (subject to a de minimis threshold), was either (i) performed by or (ii) reviewed by an independent valuation firm. All investments as of March 31, 2026 and September 30, 2025 were valued using Level 3 inputs. As of March 31, 2026 and September 30, 2025, all money market funds included in cash equivalents and restricted cash equivalents were valued using Level 1 inputs and all forward currency contracts and interest rate swaps were valued using Level 2 inputs.

When determining fair value of Level 3 debt and equity investments, the Valuation Designee takes into account the following factors, where relevant: the enterprise value of a portfolio company, the nature and realizable value of any collateral, the portfolio company’s ability to make payments and its earnings and discounted cash flows, the markets in which the portfolio company does business, comparisons to publicly traded securities, and changes in the interest rate environment and the credit markets generally that affect the price at which similar investments are made and other relevant factors. The primary method for determining enterprise value uses a multiple analysis whereby appropriate multiples are applied to the portfolio company’s net income before net interest expense, income tax expense, depreciation and amortization (“EBITDA”). A portfolio company’s EBITDA can include pro-forma adjustments for items such as acquisitions, divestitures, or expense reductions. The enterprise value analysis is performed to determine the value of equity investments and to determine if debt investments are credit impaired.

TABLE OF CONTENTS

Notes to Consolidated Financial Statements (unaudited)

(In thousands, except shares and per share data)

The Valuation Designee may also employ other valuation multiples to determine enterprise value, such as revenues. If debt investments are credit impaired, the Valuation Designee will use the enterprise value analysis or a liquidation basis analysis to determine fair value, which may include evaluating multiple recovery scenarios and weighting the expected outcomes based on their likelihood. For debt investments that are not determined to be credit impaired, the Valuation Designee uses a market interest rate yield analysis to determine fair value.

In addition, for certain debt investments, the Valuation Designee bases its valuation on indicative bid and ask prices provided by an independent third-party pricing service. Bid prices reflect the highest price that the Company and others could be willing to pay. Ask prices represent the lowest price that the Company and others could be willing to accept. The Valuation Designee generally uses the midpoint of the bid/ask range as its best estimate of fair value of such investment.

Due to the inherent uncertainty of determining the fair value of Level 3 investments that do not have a readily available market value, the fair value of the investments could differ significantly from the values that would have been used had a ready market existed for such investments and could differ materially from the values that are ultimately received or settled. Further, such investments are generally subject to legal and other restrictions or otherwise are less liquid than publicly traded instruments. If the Company were required to liquidate a portfolio investment in a forced or liquidation sale, the Company could realize significantly less than the value at which such investment had previously been recorded. The Company’s investments are subject to market risk. Market risk is the potential for changes in the value due to market changes. Market risk is directly impacted by the volatility and liquidity in the markets in which the investments are traded.

The following tables present fair value measurements of the Company’s investments and indicate the fair value hierarchy of the valuation techniques utilized to determine such fair value as of March 31, 2026 and September 30, 2025:

The above tables are not intended to be all-inclusive but rather to provide information on significant unobservable inputs and valuation techniques used by the Valuation Designee.

The significant unobservable inputs used in the fair value measurement of the Company’s debt and equity investments are EBITDA multiples, revenue multiples and market interest rates. The Valuation Designee uses EBITDA multiples and, to a lesser extent, revenue multiples on the Company’s debt and equity investments to determine any credit gains or losses. Increases or decreases in either of these inputs in isolation would have resulted in a significantly lower or higher fair value measurement. The Valuation Designee uses market interest rates for loans to determine if the effective yield on a loan is commensurate with the market yields for that type of loan. If a loan’s effective yield was significantly less than the market yield for a similar loan with a similar credit profile, then the resulting fair value of the loan could have been lower.

Other Financial Assets and Liabilities

ASC Topic 820 requires disclosure of the fair value of financial instruments for which it is practical to estimate such value. As a result, with the exception of the line item titled “debt” which is reported at cost, all assets and liabilities approximate fair value on the Consolidated Statements of Financial Condition due to their short maturity. The fair value of the Company's 2026 Notes, 2027 Notes, 2028 Notes and 2029 Notes (as defined in Note 7) is based on vendor pricing received by the Company, which is considered a Level 2 input. The fair value of the Company’s remaining debt is estimated using Level 3 inputs by discounting remaining payments using comparable market rates or market quotes for similar instruments at the measurement date, if available. The fair value of Company’s revolving credit facilities approximates the carrying value due to their variable interest rates based on selected short-term rates.

Note 8. Commitments and Contingencies

Commitments: As of March 31, 2026, the Company had outstanding commitments to fund investments totaling $680,459, including $234,009 of commitments on undrawn revolvers. As of September 30, 2025, the Company had outstanding commitments to fund investments totaling $927,887, including $252,574 of commitments on undrawn revolvers.

Indemnifications: In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties that provide general indemnifications. The Company’s maximum exposure under these arrangements is unknown, as these involve future claims against the Company that have not occurred. The Company expects the risk of any future obligations under these indemnifications to be remote.

Off-balance sheet risk: Off-balance sheet risk refers to an unrecorded potential liability that could result in a future obligation or loss, even though it does not appear on the Consolidated Statements of Financial Condition. The Company has entered and, in the future, could again enter into derivative instruments that contain elements of off-balance sheet market and credit risk. Refer to Note 5 for outstanding forward currency contracts and interest rate swap agreements as of March 31, 2026 and September 30, 2025. Derivative instruments can be affected by market conditions, such as interest rate and foreign currency volatility, which could impact the fair value of the derivative instruments. If market conditions move against the Company, it could not achieve the anticipated benefits of the derivative instruments and could realize a loss. The Company minimizes market risk through monitoring its investments and borrowings.

Concentration of credit and counterparty risk: Credit risk arises primarily from the potential inability of counterparties to perform in accordance with the terms of the contract. The Company has engaged and, in the future, may engage again in derivative transactions with counterparties. In the event that the counterparties do not fulfill their obligations, the Company could be exposed to risk. The risk of default depends on the creditworthiness of the counterparties or issuers of the instruments. The Company’s maximum loss that it could incur related to counterparty risk on its derivative instruments is the value of the collateral for that respective derivative instrument. It is the Company’s policy to review, as necessary, the credit standing of each counterparty.

Legal proceedings: In the normal course of business, the Company is subject to legal and regulatory proceedings that are generally incidental to its ongoing operations. While there can be no assurance of the ultimate disposition of any such proceedings, the Company does not believe any disposition will have a material adverse effect on the Company’s consolidated financial statements.

TABLE OF CONTENTS

Overview

We are an externally managed, closed-end, non-diversified management investment company that has elected to be regulated as a business development company under the Investment Company Act of 1940, as amended, or the 1940 Act. In addition, for U.S. federal income tax purposes, we have elected to be treated as a RIC under Subchapter M of the Internal Revenue Code of 1986, as amended, or the Code. As a business development company and a RIC, we are also subject to certain constraints, including limitations imposed by the 1940 Act and the Code.

Our shares are currently listed on The Nasdaq Global Select Market under the symbol “GBDC.”

Our investment objective is to generate current income and capital appreciation by investing primarily in one stop (a loan that combines characteristics of traditional first lien senior secured loans and second lien or subordinated loans and that are often referred to by other middle-market lenders as unitranche loans) and other senior secured loans of U.S. middle-market companies. We also selectively invest in second lien and subordinated loans of, and warrants and minority equity securities in U.S. middle-market companies. We intend to achieve our investment objective by (1) accessing the established loan origination channels developed by Golub Capital, a leading lender to U.S. middle-market companies with over $90.0 billion in capital under management(1) as of January 1, 2026, (2) selecting investments within our core middle-market company focus, (3) partnering with experienced private equity firms, or sponsors, in many cases with whom Golub Capital has invested alongside in the past, (4) implementing the disciplined underwriting standards of Golub Capital and (5) drawing upon the aggregate experience and resources of Golub Capital.

Our investment activities are managed by GC Advisors and supervised by our board of directors of which a majority of the members are independent of us, GC Advisors and its affiliates.

Under an investment advisory agreement, or the Investment Advisory Agreement, we have agreed to pay GC Advisors an annual base management fee based on our average adjusted gross assets as well as an incentive fee based on our investment performance. The Investment Advisory Agreement was most recently approved by our board of directors in May 2026. Under an administrative agreement, or the Administration Agreement, we are provided with certain administrative services by an administrator, or the Administrator, which is currently Golub Capital LLC. Under the Administration Agreement, we have agreed to reimburse the Administrator for our allocable portion (subject to the review and approval of our independent directors) of overhead and other expenses incurred by the Administrator in performing its obligations under the Administration Agreement.

We seek to create a portfolio that includes primarily one stop and other senior secured loans by primarily investing approximately $10.0 million to $85.0 million of capital, on average, in the securities of U.S. middle-market companies. We also selectively invest more than $85.0 million in some of our portfolio companies and generally expect that the size of our individual investments will vary proportionately with the size of our capital base.

We generally invest in securities that have been rated below investment grade by independent rating agencies or that would be rated below investment grade if they were rated. These securities, which are often referred to as “junk,” have predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal. In addition, many of our debt investments have floating interest rates that reset on a periodic basis and typically do not fully pay down principal prior to maturity, which could increase our risk of losing part or all of our investment.

As of March 31, 2026 and September 30, 2025, our portfolio at fair value was comprised of the following:

TABLE OF CONTENTS

One stop loans include loans to technology companies undergoing strong growth due to new services, increased adoption and/or entry into new markets. We refer to loans to these companies as recurring revenue loans. Other targeted characteristics of recurring revenue businesses include strong customer revenue retention rates, a diversified customer base and backing from growth equity or venture capital firms. In some cases, the borrower’s high revenue growth is supported by a high level of discretionary spending. As part of the underwriting of such loans and consistent with industry practice, we adjust our characterization of the earnings of such borrowers for a reduction or elimination of such discretionary expenses, if appropriate. As of March 31, 2026 and September 30, 2025, one stop loans included $630.1 million and $771.9 million, respectively, of recurring revenue loans at fair value.

As of March 31, 2026 and September 30, 2025, we had debt and equity investments in 420 and 417 portfolio companies, respectively.

Revenues: We generate revenue in the form of interest and fee income on debt investments and capital gains and distributions, if any, on portfolio company investments that we originate or acquire. Our debt investments, whether in the form of senior secured, one stop, second lien or subordinated loans, typically have a term of three to seven years and bear interest at a fixed or floating rate. In some instances, we receive payments on our debt investments based on scheduled amortization of the outstanding balances. In addition, we receive repayments of some of our debt investments prior to their scheduled maturity date. The frequency or volume of these repayments fluctuates significantly from period to period. Our portfolio activity also reflects the proceeds of sales of securities.

In some cases, our investments provide for deferred interest payments or PIK interest. The principal amount of loans and any accrued but unpaid interest generally become due at the maturity date.

TABLE OF CONTENTS

In addition, we generate revenue in the form of commitment, origination, amendment, structuring or due diligence fees, fees for providing managerial assistance, administrative agent fees and consulting fees. Loan origination fees, original issue discount and market discount or premium are capitalized, and we accrete or amortize such amounts as interest income. We record prepayment premiums on loans as fee income. For additional details on revenues, see “Critical Accounting Policies—Revenue Recognition.” We recognize realized gains or losses on investments based on the difference between the net proceeds from the disposition and the amortized cost basis of the investment or derivative instrument, without regard to unrealized gains or losses previously recognized. We record current period changes in fair value of investments and derivative instruments that are measured at fair value as a component of the “Net change in unrealized appreciation (depreciation) on investment transactions” in the Consolidated Statements of Operations.

Expenses: Our primary operating expenses include the payment of fees to GC Advisors under the Investment Advisory Agreement and interest expense on our outstanding debt. We bear all other out-of-pocket costs and expenses of our operations and transactions, including:

•calculating our net asset value, or NAV (including the cost and expenses of any independent valuation firm);

•fees and expenses incurred by GC Advisors payable to third parties, including agents, consultants or other advisors, in monitoring financial and legal affairs for us and in monitoring our investments and performing due diligence on our prospective portfolio companies or otherwise relating to, or associated with, evaluating and making investments, which fees and expenses include, among other items, due diligence reports, appraisal reports, any studies commissioned by GC Advisors and travel and lodging expenses;

•expenses related to unsuccessful portfolio acquisition efforts;

•offerings of our common stock and other securities;

•administration fees and expenses, if any, payable under the Administration Agreement (including payments based upon our allocable portion of the Administrator’s overhead in performing its obligations under the Administration Agreement, including rent and the allocable portion of the cost of our chief compliance officer, chief financial officer and their respective staffs);

•fees payable to third parties, including agents, consultants or other advisors, relating to, or associated with, evaluating and making investments in portfolio companies, including costs associated with meeting financial sponsors;

•transfer agent, dividend agent and custodial fees and expenses;

•U.S. federal and state registration and franchise fees;

•all costs of registration and listing our shares on any securities exchange;

•U.S. federal, state and local taxes;

•independent directors’ fees and expenses;

•costs of preparing and filing reports or other documents required by the SEC or other regulators;

•costs of any reports, proxy statements or other notices to stockholders, including printing costs;

•costs associated with individual or group stockholders;

•costs associated with compliance under the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act;

•our allocable portion of any fidelity bond, directors and officers/errors and omissions liability insurance, and any other insurance premiums;

•direct costs and expenses of administration, including printing, mailing, long distance telephone, copying, secretarial and other staff, independent auditors and outside legal costs;

•proxy voting expenses; and

•all other expenses incurred by us or the Administrator in connection with administering our business.

We expect our general and administrative expenses to be relatively stable or decline as a percentage of total assets during periods of asset growth and to increase during periods of asset declines.

Consolidated Results of Operations

In addition to our analysis of the year-to-date reporting period compared to the year-to-date prior periods, we are presenting our analysis for the reporting quarter compared to the immediately preceding quarter as we believe this comparison will provide a more meaningful analysis of our business as our results are largely driven by market changes, not seasonal business activity.

Consolidated operating results for the three months ended March 31, 2026 and December 31, 2025 and the six months ended March 31, 2026 and March 31, 2025 are as follows:

Net income can vary substantially from period to period for various reasons, including the recognition of realized gains and losses and unrealized appreciation and depreciation. As a result, comparisons of operating results may not be meaningful.

On September 16, 2019, and June 3, 2024, we completed our acquisitions of GCIC and GBDC 3, respectively. Each acquisition was accounted for under the asset acquisition method of accounting in accordance with Accounting Standards Codification, or ASC, 805-50, Business Combinations — Related Issues. Under asset acquisition accounting, where the consideration paid to GCIC and GBDC 3’s stockholders exceeded the relative fair values of the assets acquired and liabilities assumed, the premium paid by us was allocated to the cost of the GCIC and GBDC 3 investments acquired by us pro-rata based on their relative fair value. Immediately following each acquisition of GCIC and GBDC 3, we recorded its assets at their respective fair values and, as a result, the purchase premium allocated to the cost basis of the GCIC and GBDC 3 assets acquired was immediately recognized as unrealized depreciation on our Consolidated Statement of Operations. The purchase premium allocated to investments in loan securities will amortize over the life of the loans through interest income with a corresponding reversal of the unrealized depreciation on such loans acquired through their ultimate disposition. The purchase premium allocated

TABLE OF CONTENTS

to investments in equity securities will not amortize over the life of the equity securities through interest income and, assuming no subsequent change to the fair value of the equity securities acquired from GCIC and GBDC 3 and disposition of such equity securities at fair value, we will recognize a realized loss with a corresponding reversal of the unrealized depreciation upon disposition of the equity securities acquired.

As a supplement to our GAAP financial measures, we have provided the following non-GAAP financial measures that we believe are useful for the reasons described below:

•“Adjusted Net Investment Income” - excludes the amortization of the purchase price premium from net investment income calculated in accordance with GAAP;

•“Adjusted Net Investment Income Before Accrual for Capital Gain Incentive Fee” - Adjusted Net Investment Income excluding the accrual or reversal for the capital gain incentive fee under GAAP;

•“Adjusted Net Realized and Unrealized Gain/(Loss)” - excludes the unrealized loss resulting from the purchase premium write-down and the corresponding reversal of the unrealized loss resulting from the amortization of the premium on loans or from the sale of equity investments from the determination of realized and unrealized gain/(loss) determined in accordance with GAAP; and

•“Adjusted Net Income” – calculates net income and earnings per share based on Adjusted Net Investment Income and Adjusted Net Realized and Unrealized Gain/(Loss).

Adjusted Net Income $ (46,796) $ 65,246 $ 18,450 $ 190,298

We believe that excluding the financial impact of the GCIC/GBDC 3 acquisition purchase premium in the above non-GAAP financial measures is useful for investors as this is a non-cash expense/loss and is one method we use to measure our results of operations. In addition, we believe that providing the Adjusted Net Investment Income Before Accrual for Capital Gain Incentive Fee is a useful non-GAAP financial measure as such accrual is not contractually payable under the terms of the Investment Advisory Agreement.

Although these non-GAAP financial measures are intended to enhance investors’ understanding of our business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP.

Investment Income

Investment income decreased from the three months ended December 31, 2025 to the three months ended March 31, 2026 by $18.9 million. The decrease was primarily due to a decrease in interest income as a result of (1) a decrease in the average earning debt investments balance of $262.9 million, (2) the delayed impact of interest base rate reductions from December 2025 and (3) $1.5 million of previously accrued interest income that was recharacterized as payment-in-kind (“PIK”) interest income as such amounts were capitalized and added to the principal balance of certain loans during the period. Investment income decreased from the six months ended March 31, 2025 to the six months ended March 31, 2026 by $39.5 million, primarily due to a decrease in interest income as a result of declining interest base rates and, to a lesser extent, spread compression on new and amended debt investments that was partially offset by interest income earned on an increase in the average earning debt investments balance of $74.1 million. For the three and six months ended March 31, 2026, PIK interest income represented 9.0% and 7.9%, respectively, of total investment income excluding amortization of purchase premium for the GCIC/GBDC 3 acquisitions. For the three and six months ended March 31, 2025, PIK interest income represented 6.4% and 5.6%, respectively, of total investment income excluding amortization of purchase premium for the GCIC/GBDC 3 acquisitions.

The annualized income yield by debt security type for the three months ended March 31, 2026 and December 31, 2025 and the six months ended March 31, 2026 and March 31, 2025 are as follows:

Three months ended Six months ended
March 31, 2026 December 31, 2025 March 31, 2026 March 31, 2025
Senior secured 9.0% 9.4% 9.2% 10.3%
One stop 9.2% 9.6% 9.4% 10.5%
Second lien 13.1% 13.3% 13.2% 13.5%
Subordinated debt 13.4% 13.4% 13.4% 13.8%

Income yields on senior secured and one stop loans decreased for the three months ended March 31, 2026 as compared to the three months ended December 31, 2025 primarily due to the delayed impact of interest base rate reductions in December 2025. Income yields on senior secured and one stop loans decreased for the six months ended March 31, 2026 as compared to the six months ended March 31, 2025, primarily due to declining interest base rates and, to a lesser extent, spread compression on new and amended debt investments. Our loan portfolio is partially insulated from a drop in floating interest rates, as 97.8% of the loan portfolio at fair value is subject to an interest rate floor. As of March 31, 2026 and September 30, 2025, the weighted average base rate floor of our loans was 0.77% and 0.78%, respectively.

As of March 31, 2026, we have second lien investments in three portfolio companies and subordinated debt investments in seven portfolio companies as shown in the Consolidated Schedule of Investments. Due to the limited number of second lien and subordinated debt investments, income yields on second lien and subordinated debt investments can be significantly impacted by the addition, subtraction or refinancing of one investment.

Interest Expense

Interest and other debt financing expenses, net of amortization of debt issuance costs, decreased from the three months ended December 31, 2025 to the three months ended March 31, 2026 by $5.2 million, primarily due to a decrease in interest expense as a result of (1) a decrease in the average debt outstanding of $244.2 million and (2) lower interest base rates on our floating rate borrowings. Interest and other debt financing expenses, including amortization of debt issuance costs, decreased from the six months ended March 31, 2025 to the six months ended March 31, 2026 by $22.2 million, primarily due to reduced borrowing costs resulting from (i) the debt capital refinancings completed during the fiscal year 2025 first quarter, including the 2024 Debt Securitization issuance of $1.3 billion in notes which bear interest at a weighted-average rate of three-month SOFR + 1.58%, (ii) the April 2025 amendment to the JPM Credit Facility that reduced the applicable margin to a range of 1.525% to 1.775% from a range of 1.75% to 1.875% and (iii) decreasing interest base rates on our floating rate borrowings. For more information about our outstanding borrowings for the three and six months ended March 31, 2026 and 2025, including the terms thereof, see Note 7 in the notes to our consolidated financial statements and the “Liquidity and Capital Resources” section below.

For the three months ended March 31, 2026 and December 31, 2025, the effective annualized average interest rate1 on our total debt was 5.2% and 5.4%, respectively. For the six months ended March 31, 2026 and 2025, the effective annualized average interest rate1 on our total debt was 5.3% and 6.0%, respectively. The effective annualized average interest rate1 decreased for the three months ended March 31, 2026 compared to the three months ended December 31, 2025 due to lower interest base rates on our floating rate borrowings. The effective annualized average interest rate1 decreased for the six months ended March 31, 2026 compared to the six months ended March 31, 2025 primarily due to reduced borrowing costs resulting from (1) the debt capital refinancing completed during fiscal year 2025, (2) the April 2025 amendment to the JPM Credit Facility that reduced the applicable margin and (3) decreasing interest base rates on our floating rate borrowings.

Management Fee

The base management fee decreased from the three months ended December 31, 2025 to the three months ended March 31, 2026 primarily due to a decrease in average adjusted gross assets from the three months ended December 31, 2025 to the three months ended March 31, 2026.

The base management fee decreased from the six months ended March 31, 2025 to the six months ended March 31, 2026 primarily due to a decrease in average adjusted gross assets from the six months ended March 31, 2025 to the six months ended March 31, 2026.

1 The effective average interest rate includes amortization of debt financing costs, amortization of discounts on notes issued and non-usage facility fees and the net contractual interest rate swap expense on the 2028 and 2029 Notes but excluding the net unrealized gain/(loss) related to the fair value hedges associated with the 2028 and 2029 Notes interest rate swaps.

TABLE OF CONTENTS

Incentive Fees

The incentive fee payable under the Investment Advisory Agreement consists of two parts: (1) the income component, or the Income Incentive Fee, and (2) the capital gains component, or the Capital Gain Incentive Fee.

The Income Incentive Fee decreased by $1.9 million from the three months ended December 31, 2025 to the three months ended March 31, 2026 primarily due to a decrease in Pre-Incentive Fee Net Investment Income. The Income Incentive Fee decreased by $3.3 million from the six months ended March 31, 2025 to the six months ended March 31, 2026 primarily due to a decrease in Pre-Incentive Fee Net Investment Income and a lower rate of return on the value of our net assets driven by a decrease in the investment income yield on our investment portfolio due to declining interest base rates and a decrease in our average earning debt investments. For each of the three months ended March 31, 2026 and December 31, 2025 and the six months ended March 31, 2026 and March 31, 2025, we were fully through the Income Incentive Fee “catch-up” provision and the Income Incentive Fee was equal to 15% of Pre-Incentive Fee Net Investment Income.

As of March 31, 2026 and September 30, 2025, there was no Capital Gain Incentive Fee payable as calculated under the Investment Advisory Agreement. In accordance with GAAP, we are required to include the aggregate unrealized capital appreciation on investments in the calculation and accrue a capital gain incentive fee as if such unrealized capital appreciation were realized, even though such unrealized capital appreciation is not permitted to be considered in calculating the fee actually payable under the Investment Advisory Agreement. As of March 31, 2026 and September 30, 2025, there was no capital gain incentive fee accrual calculated in accordance with GAAP. Any payment due under the terms of the Investment Advisory Agreement is calculated in arrears at the end of each calendar year. No Capital Gain Incentive Fees as calculated under the Investment Advisory Agreement or any prior investment advisory agreements, as applicable, have been payable since December 31, 2018.

For additional details on unrealized appreciation and depreciation of investments, refer to the “Net Realized and Unrealized Gains and Losses” section below.

Professional Fees, Administrative Service Fee and General and Administrative Expenses

In total, the administrative service fee, professional fees and general and administrative expenses decreased by $0.4 million from the three months ended December 31, 2025 to the three months ended March 31, 2026, primarily due to decreases across each of these expense categories.

In total, professional fees, the administrative service fee and general and administrative expenses decreased by $0.4 million from the six months ended March 31, 2025 to the six months ended March 31, 2026, primarily due to a decrease in professional fees and general and administrative expenses that was partially offset by an increase in the administrative service fee.

The Administrator pays for certain expenses incurred by us. These expenses are subsequently reimbursed in cash. Total expenses reimbursed to the Administrator during the three months ended March 31, 2026 and December 31, 2025 and the six months ended March 31, 2026 and March 31, 2025 were $2.6 million, $2.5 million, $5.1 million, and $4.4 million, respectively.

As of March 31, 2026 and September 30, 2025, included in accounts payable and other liabilities were $1.1 million and $2.5 million, respectively, of expenses paid on behalf of us by the Administrator.

During the six months ended March 31, 2026, we had a net realized loss of $14.2 million, primarily attributable to (i) $10.0 million of net realized losses recognized on the settlement of forward currency contracts and translation of foreign currency amounts and transactions into U.S. dollars and (ii) realized losses recognized on the restructuring of two portfolio company investments. During the six months ended March 31, 2025, we had a net realized loss of $38.9 million, primarily attributable to realized losses recognized on the restructuring of debt and equity investments of multiple portfolio company investments and the sale of a portfolio company debt investment that was partially offset by net realized gains recognized on the settlement of forward currency contracts and translation of foreign currency amounts and transactions into U.S. dollars.

For the three months ended March 31, 2026, we had $11.1 million in unrealized appreciation on 103 portfolio company investments, which was offset by $145.3 million in unrealized depreciation on 343 portfolio company investments.

Unrealized appreciation for the three months ended March 31, 2026 was primarily due to increases in the fair values of certain equity investments and the reversal of previously recognized unrealized depreciation on the restructuring of a portfolio company investment. Unrealized appreciation for the three months ended December 31, 2025 was primarily due to increases in the fair value of certain equity investments and the reversal of previously recognized unrealized depreciation on the restructuring of a portfolio company investment.

Due to the interplay of the 1940 Act restrictions on principal and joint transactions and the U.S. risk retention rules adopted pursuant to Section 941 of Dodd-Frank, as a business development company, we sought and received no action relief from the SEC to ensure we could engage in CLO financings in which assets are transferred through GC Advisors.

As of March 31, 2026 and September 30, 2025, following an amendment to the 2023 Equity Distribution Agreement in May 2025 to increase the aggregate offering amount by $38.0 million, common stock with an aggregate offering amount of $250.0 million remained available for issuance under the 2023 Distribution Agreement.

Asset Coverage, Contractual Obligations, Off-Balance Sheet Arrangements and Other Liquidity Considerations

As of March 31, 2026, in accordance with the 1940 Act, with certain limited exceptions, we were allowed to borrow amounts such that our asset coverage, as defined in the 1940 Act, is at least 150% after such borrowing. Prior to February 6, 2019, in accordance with the 1940 Act, with certain limited exceptions, we were allowed to borrow amounts such that our asset coverage, as defined in the 1940 Act, was at least 200% after such borrowing. We currently intend to continue to target a GAAP debt-to-equity ratio between 0.85x to 1.25x. As of March 31, 2026, our asset coverage for borrowed amounts and GAAP debt-to-equity ratio was 178.8% and 1.27x, respectively, and our GAAP debt-to-equity ratio, net, which reduces total debt by cash, cash equivalents, foreign currencies and restricted cash held for partial repayment on notes of certain of our securitization vehicles past their reinvestment period term (if any) was 1.24x as of March 31, 2026.

On August 1, 2025, our board of directors re-approved the Program (as defined in Note 2 of our consolidated financial statements), which allows us to repurchase up to $150.0 million of our outstanding common stock, exclusive of shares repurchased prior to the date of such authorization, on the open market at prices below the NAV per share as reported in our then most recently published consolidated financial statements. The Program is implemented at the discretion of management with shares to be purchased from time to time at prevailing market prices, through open market transactions, including block transactions, in accordance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended. During the six months ended March 31, 2026, we repurchased 4.9 million shares of our common stock for an aggregate repurchase price of approximately $63.7 million. During the six months ended March 31, 2025, we repurchased 77,777 shares of our common stock for an aggregate repurchase price of approximately $1.1 million.

As of March 31, 2026 and September 30, 2025, we had outstanding commitments to fund investments totaling $680.5 million and $927.9 million, respectively. As of March 31, 2026, total commitments of $680.5 million included $234.0 million of unfunded commitments on revolvers. There is no guarantee that these amounts will be funded to the borrowing party now or in the future. The unfunded commitments relate to loans with various maturity dates, but the entire amount was eligible for funding to the borrowers, subject to the terms of each loan’s respective

credit agreement. A summary of maturity requirements for our principal borrowings as of March 31, 2026 is included in Note 7 of our consolidated financial statements. We did not have any other material contractual payment obligations as of March 31, 2026. As of March 31, 2026, we believe that we had sufficient assets and liquidity to adequately cover future obligations under our unfunded commitments based on historical rates of drawings upon unfunded commitments, cash and restricted cash balances that we maintain, availability under the Adviser Revolver and JPM Credit Facility, as well as ongoing principal repayments on debt investments. In addition, we generally hold some syndicated loans in larger portfolio companies that are saleable over a relatively short period to generate cash.

In addition, we have entered and, in the future, could again enter into derivative instruments that contain elements of off-balance sheet market and credit risk. Refer to Note 5 of our consolidated financial statements for outstanding forward currency contracts and interest rate swap agreements as of March 31, 2026 and September 30, 2025. Derivative instruments can be affected by market conditions, such as interest rate volatility, which could impact the fair value of the derivative instruments. If market conditions move against us, we may not achieve the anticipated benefits of the derivative instruments and could realize a loss. We minimize market risk through monitoring its investments and borrowings.

Although we expect to fund the growth of our investment portfolio through the net proceeds from future securities offerings and future borrowings, to the extent permitted by the 1940 Act, we cannot assure you that our efforts to raise capital will be successful. In addition, from time to time, we can amend or refinance our leverage facilities and securitization financings, to the extent permitted by applicable law. In addition to capital not being available, it also could not be available on favorable terms. To the extent we are not able to raise capital on what we believe are favorable terms, we will focus on optimizing returns by investing capital generated from repayments into new investments we believe are attractive from a risk/reward perspective. Furthermore, to the extent we are not able to raise capital and are at or near our targeted leverage ratios, we expect to receive smaller allocations, if any, on new investment opportunities under GC Advisors’ allocation policy and have, in the past, received such smaller allocations under similar circumstances.

(1)As of March 31, 2026, $1,640.9 million and $1,551.1 million of our loans at amortized cost and fair value, respectively, included a feature permitting a portion of the interest due on such loan to be PIK interest. As of March 31, 2026, $116.1 million and $64.5 million at amortized cost and fair value, respectively, of our loans with a PIK feature were on non-accrual status.

(2)As of September 30, 2025, $1,520.7 million and $1,476.5 million of our loans at amortized cost and fair value, respectively, included a feature permitting a portion of the interest due on such loan to be PIK interest. As of September 30, 2025, $51.3 million and $24.1 million at amortized cost and fair value, respectively, of our loans with a PIK feature were on non-accrual status.

(3)We refer to a loan as non-accrual when we cease recognizing interest income on the loan because we have stopped pursuing repayment of the loan or, in certain circumstances, it is past due 90 days or more on principal, interest or our management has reasonable doubt that principal or interest will be collected. Preferred equity securities accruing contractual PIK dividend income may be placed on non-accrual status if there is reasonable doubt that the amortized cost or capitalized PIK and non-cash dividend income is collectible. See “— Critical Accounting Policies — Revenue Recognition.”

As of March 31, 2026, we had loans in fifteen portfolio companies and preferred equity securities in four portfolio companies on non-accrual status, and non-accrual investments as a percentage of total investments at cost and fair value were 2.3% and 1.4%, respectively. As of September 30, 2025, we had loans in eight portfolio companies and preferred equity securities in one portfolio company on non-accrual status, and non-accrual investments as a percentage of total investments at cost and fair value were 0.6% and 0.3%, respectively.

As of March 31, 2026 and September 30, 2025, the fair value of our debt investments as a percentage of the outstanding principal value was 96.8% and 98.4%, respectively.

TABLE OF CONTENTS

As part of the monitoring process, GC Advisors regularly assesses the risk profile of each of our investments and rates each of them based on an internal system developed by Golub Capital and its affiliates. This system is not generally accepted in our industry or used by our competitors. It is based on the following categories, which we refer to as GC Advisors’ internal performance ratings:

Internal Performance Ratings
Rating Definition
5 Involves the least amount of risk in our portfolio. The borrower is performing above expectations, and the trends and risk factors are generally favorable.
4 Involves an acceptable level of risk that is similar to the risk at the time of origination. The borrower is generally performing as expected, and the risk factors are neutral to favorable.
3 Involves a borrower performing below expectations and indicates that the loan’s risk has increased somewhat since origination. The borrower could be out of compliance with debt covenants; however, loan payments are generally not past due.
2 Involves a borrower performing materially below expectations and indicates that the loan’s risk has increased materially since origination. In addition to the borrower being generally out of compliance with debt covenants, loan payments could be past due (but generally not more than 180 days past due).
1 Involves a borrower performing substantially below expectations and indicates that the loan’s risk has substantially increased since origination. Most or all of the debt covenants are out of compliance and payments are substantially delinquent. Loans rated 1 are not anticipated to be repaid in full and we will reduce the fair market value of the loan to the amount we anticipate will be recovered.

Our internal performance ratings do not constitute any rating of investments by a nationally recognized statistical rating organization or represent or reflect any third-party assessment of any of our investments.

For any investment rated 1, 2 or 3, GC Advisors will increase its monitoring intensity and prepare regular updates for the investment committee, summarizing current operating results and material impending events and suggesting recommended actions.

GC Advisors monitors and, when appropriate, changes the internal performance ratings assigned to each investment in our portfolio. In connection with our valuation process, GC Advisors and our board of directors review these internal performance ratings on a quarterly basis.

TABLE OF CONTENTS

Distributions

We intend to make quarterly distributions to our stockholders as determined by our board of directors. For additional details on distributions, see “Income taxes” in Note 2 to our consolidated financial statements.

We may not be able to achieve operating results that will allow us to make distributions at a specific level or to increase the amount of our distributions from time to time. In addition, the asset coverage requirements applicable to us as a business development company under the 1940 Act could limit our ability to make distributions. If we do not distribute a certain percentage of our income annually, we will suffer adverse U.S. federal income tax consequences, including the possible loss of our ability to be subject to tax as a RIC. We cannot assure stockholders that they will receive any distributions.

Because federal income tax regulations differ from GAAP, distributions in accordance with tax regulations can differ from net investment income and realized gains recognized for financial reporting purposes. Differences are permanent or temporary. Permanent differences are reclassified within capital accounts in the financial statements to reflect their tax character. For example, permanent differences in classification result from the treatment of distributions paid from short-term gains as ordinary income dividends for tax purposes. Temporary differences arise when certain items of income, expense, gain or loss are recognized at some time in the future.

To the extent our taxable earnings fall below the total amount of our distributions for any tax year, a portion of those distributions could be deemed a return of capital to our stockholders for U.S. federal income tax purposes. Thus, the source of a distribution to our stockholders could be the original capital invested by the stockholder rather than our income or gains. Stockholders should read any written disclosure accompanying a distribution payment carefully and should not assume that the source of any distribution is our ordinary income or gains.

We have adopted an “opt out” dividend reinvestment plan for our common stockholders. As a result, if we declare a distribution, our stockholders’ cash distributions will be automatically reinvested in additional shares of our common stock unless a stockholder specifically “opts out” of our dividend reinvestment plan. If a stockholder opts out, that stockholder will receive cash distributions. Although distributions paid in the form of additional shares of our common stock will generally be subject to U.S. federal, state and local taxes in the same manner as cash distributions, stockholders participating in our dividend reinvestment plan will not receive any corresponding cash distributions with which to pay any such applicable taxes.

Related Party Transactions

We have entered into a number of business relationships with affiliated or related parties, including the following:

•We entered into the Investment Advisory Agreement with GC Advisors. Mr. Lawrence Golub, chief executive officer of GC Advisors and an interested director of Golub Capital BDC, and Mr. David Golub, our chairman and chief executive officer, are managers of GC Advisors, and each of Messrs. Lawrence Golub and David Golub own an indirect pecuniary interest in GC Advisors. The Board most recently approved an amended and restated Investment Advisory Agreement in May 2026.

•Golub Capital LLC provides, and other affiliates of Golub Capital have historically provided, us with the office facilities and administrative services necessary to conduct day-to-day operations pursuant to our Administration Agreement.

•We have entered into a license agreement with Golub Capital LLC, pursuant to which Golub Capital LLC has granted us a non-exclusive, royalty-free license to use the name “Golub Capital.”

•Under a staffing agreement, or the Staffing Agreement, Golub Capital LLC has agreed to provide GC Advisors with the resources necessary to fulfill its obligations under the Investment Advisory Agreement. The Staffing Agreement provides that Golub Capital LLC will make available to GC Advisors experienced investment professionals and provide access to the senior investment personnel of Golub Capital LLC for purposes of evaluating, negotiating, structuring, closing and monitoring our investments. The Staffing Agreement also includes a commitment that the members of GC Advisors’ investment committee will serve in such capacity. Services under the Staffing Agreement are provided on a direct cost reimbursement basis. We are not a party to the Staffing Agreement.

•GC Advisors serves as the collateral manager to the 2024 Issuer under the 2024 Issuer Collateral Management Agreement. Fees payable to GC Advisors for providing these services offset against the base management fee payable by us under the Investment Advisory Agreement.

•We have entered into the Adviser Revolver with GC Advisors in order to have the ability to borrow funds on a short-term basis.

•During the first calendar quarter of 2026, the Golub Capital Employee Grant Program Rabbi Trust, or the Trust, purchased approximately $18.7 million, or 1,500,000 shares of our common stock for the purpose of awarding incentive compensation to employees of Golub Capital. During the calendar year 2025, the Trust purchased approximately $45.1 million, or 3,089,459 shares of our common stock, for the purpose of awarding incentive compensation to employees of Golub Capital.

•On September 16, 2019, we completed our acquisition of GCIC pursuant to the GCIC Merger Agreement.

•On June 3, 2024, we completed our acquisition of GBDC 3, pursuant to the GBDC 3 Merger Agreement.

GC Advisors also sponsors or manages, and expects in the future to sponsor or manage, other investment funds, accounts or investment vehicles (together referred to as “accounts”) that have investment mandates that are similar, in whole and in part, with ours. For example, GC Advisors presently serves as the investment adviser to Golub Capital Direct Lending Corporation, or GDLC, Golub Capital Direct Lending Unlevered Corporation, or GDLCU, Golub Capital BDC 4, Inc., or GBDC 4, Golub Capital Private Credit Fund, or GCRED, Golub Capital Private Income Fund I, or GPIF I, and Golub Capital Private Income Fund S, or GPIF S, all of which are unlisted business development companies that primarily focus on investing in one stop and other senior secured loans. In addition, our officers and directors serve in similar capacities for GDLC, GDLCU, GBDC 4, GCRED, GPIF I and GPIF S. If GC Advisors and its affiliates determine that an investment is appropriate for us, GDLC, GDLCU, GBDC 4, GCRED, GPIF I, GPIF S and other accounts, depending on the availability of such investment and other appropriate factors, and pursuant to GC Advisors’ allocation policy, GC Advisors or its affiliates could determine that we should invest side-by-side with one or more other accounts. We do not intend to make any investments if they are not permitted by applicable law and interpretive positions of the SEC and its staff, or if they are inconsistent with GC Advisors’ allocation procedures.

In addition, we have adopted a formal code of ethics that governs the conduct of our and GC Advisors’ officers, directors and employees. Our officers and directors also remain subject to the duties imposed by both the 1940 Act and the General Corporation Law of the State of Delaware.

TABLE OF CONTENTS

Critical Accounting Policies

The preparation of financial statements and related disclosures in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the periods reported. Actual results could materially differ from those estimates. We have identified the following items as critical accounting policies.

Fair Value Measurements

We value investments for which market quotations are readily available at their market quotations. However, a readily available market value is not expected to exist for many of the investments in our portfolio, and we value these portfolio investments at fair value as determined in good faith.

Pursuant to Rule 2a-5 under the 1940 Act, our board of directors, as permitted, has designated GC Advisors as our valuation designee (the “Valuation Designee”) to perform the determination of fair value of our investments for which market quotations are not readily available, or valued by a third-party pricing service, in accordance with our valuation policies and procedures, subject to the oversight of our board of directors.

Valuation methods include comparisons of the portfolio companies to peer companies that are public, determination of the enterprise value of a portfolio company, discounted cash flow analysis and a market interest rate approach. The factors that are taken into account in fair value pricing investments include: available current market data, including relevant and applicable market trading and transaction comparables; applicable market yields and multiples; security covenants; call protection provisions; information rights; the nature and realizable value of any collateral; the portfolio company’s ability to make payments, its earnings and discounted cash flows and the markets in which it does business; comparisons of financial ratios of peer companies that are public; comparable merger and acquisition transactions; and the principal market and enterprise values. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, the Valuation Designee will consider the pricing indicated by the external event to corroborate the private equity valuation. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the investments can differ significantly from the values that would have been used had a readily available market value existed for such investments and differ materially from values that are ultimately received or settled.

Our Valuation Designee is ultimately and solely responsible for determining, in good faith, the fair value of investments that are not publicly traded, whose market prices are not readily available on a quarterly basis or any other situation where portfolio investments require a fair value determination. As part of the valuation process described below, the Valuation Designee discusses the valuation conclusions and determined the fair value of each portfolio investment in good faith.

For periods ending on or before December 31, 2025, with respect to investments that are not publicly-traded or whose market price is not otherwise (a) readily available or (b) provided by a third-party pricing service or other quote: Our quarterly valuation process began with each portfolio company investment being initially valued by the investment professionals of the Valuation Designee responsible for the valuation function, with preliminary valuation conclusions documented and discussed with senior management. At least every other quarter, the valuation for each portfolio investment, subject to a de minimis threshold, was reviewed by an independent valuation firm. This valuation process was conducted at the end of each fiscal quarter, with each portfolio investment being reviewed at least every other quarter (subject to a de-minimis threshold) with approximately 50% (based on the fair value of portfolio company investments) of our valuations of debt and equity investments without readily available market quotations subject to review by an independent valuation firm.

For periods ending after December 31, 2025, with respect to investments that are not publicly-traded or whose market price is not otherwise (a) readily available or (b) provided via a third-party pricing service or other quote, Valuation Designee undertakes a multi-step valuation process each month. This monthly valuation process begins with each portfolio investment being initially valued either by (i) professionals of the Valuation Designee responsible for the valuation function or (ii) independent valuation firms that have been engaged to support the valuation of portfolio investments. Preliminary valuation conclusions are then documented and discussed with senior management and, in the case of valuations prepared by independent valuation firms, the Valuation Designee. Each month the valuation for each portfolio investment, or approximately 100% (based on the fair value of portfolio company investments) of our debt and equity investments without readily available market quotations (subject to a de minimis threshold) is either (i) performed by or (ii) reviewed by an independent valuation firm.

TABLE OF CONTENTS

Determination of fair values involves subjective judgments and estimates. Under current accounting standards, the notes to our consolidated financial statements refer to the uncertainty with respect to the possible effect of such valuations, and any change in such valuations, on our consolidated financial statements.

We follow ASC Topic 820 for measuring fair value. Fair value is the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters, or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation models involve some level of estimation and judgment, the degree of which is dependent on the price transparency for the assets or liabilities or market and the assets’ or liabilities’ complexity. Our fair value analysis, currently undertaken by the Valuation Designee, includes an analysis of the value of any unfunded loan commitments. Assets and liabilities are categorized for disclosure purposes based upon the level of judgment associated with the inputs used to measure their value. The valuation hierarchical levels are based upon the transparency of the inputs to the valuation of the asset or liability as of the measurement date. The three levels are defined as follows:

Level 1: Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2: Inputs include quoted prices for similar assets or liabilities in active markets and inputs that are observable for the assets or liabilities, either directly or indirectly, for substantially the full term of the assets or liabilities.

Level 3: Inputs include significant unobservable inputs for the assets or liabilities and include situations where there is little, if any, market activity for the assets or liabilities. The inputs into the determination of fair value are based upon the best information available and could require significant management judgment or estimation.

In certain cases, the inputs used to measure fair value could fall into different levels of the fair value hierarchy. In such cases, an asset’s or a liability’s categorization within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and we consider factors specific to the asset or liability. The Valuation Designee assesses the levels of assets and liabilities at each measurement date, and transfers between levels are recognized on the actual date of the event or change in circumstances that caused the transfers. There were no transfers among Level 1, 2 and 3 of the fair value hierarchy for assets and liabilities during the six months ended March 31, 2026 and 2025. The following section describes the valuation techniques used by us to measure different assets and liabilities at fair value and includes the level within the fair value hierarchy in which the assets and liabilities are categorized.

TABLE OF CONTENTS

Valuation of Investments

Level 1 investments are valued using quoted market prices. Level 2 investments are valued using market consensus prices that are corroborated by observable market data and quoted market prices for similar assets and liabilities. Level 3 investments are valued at fair value as determined in good faith by the Valuation Designee, based on input of the Valuation Designee’s personnel and independent valuation firms that have been engaged by or at the direction of the Valuation Designee to assist in the valuation of each portfolio investment without a readily available market quotation in accordance with the multi-step valuation process described above in “ — Fair Value Measurements”. For periods ending on or before December 31, 2025, at least every other quarter, the valuation for each portfolio investment (subject to a de minimis threshold) was reviewed by an independent valuation firm. This valuation process was conducted at the end of each fiscal quarter, with each portfolio investment being reviewed at least every other quarter (subject to a de-minimis threshold) with approximately 50% (based on the fair value of portfolio company investments) of our valuations of debt and equity investments without readily available market quotations subject to review by an independent valuation firm. For periods beginning after December 31, 2025, the valuation process is conducted on a monthly basis and this monthly valuation process begins with each portfolio investment being initially valued, based on the fair value methodology in accordance with ASC Topic 820 described below, either by (i) professionals of the Valuation Designee responsible for the valuation function or (ii) investment valuation firms that have been engaged to support the valuation of portfolio investments. Each month the valuation for each portfolio investment, or approximately 100% (based on the fair value of portfolio company investments) of our debt and equity investments without readily available market quotations (subject to a de minimis threshold) was either (i) performed by or (ii) reviewed by an independent valuation firm. All investments as of March 31, 2026 and September 30, 2025 were valued using Level 3 inputs. As of March 31, 2026 and September 30, 2025, all money market funds included in cash equivalents and restricted cash equivalents were valued using Level 1 inputs and all forward currency contracts and interest rate swaps were valued using Level 2 inputs.

When determining fair value of Level 3 debt and equity investments, the Valuation Designee could take into account the following factors, where relevant: the enterprise value of a portfolio company, the nature and realizable value of any collateral, the portfolio company’s ability to make payments and its earnings and discounted cash flows, the markets in which the portfolio company does business, comparisons to publicly traded securities, and changes in the interest rate environment and the credit markets generally that could affect the price at which similar investments could be made and other relevant factors. The primary method for determining enterprise value uses a multiple analysis whereby appropriate multiples are applied to the portfolio company’s EBITDA. A portfolio company’s EBITDA could include pro-forma adjustments for items such as acquisitions, divestitures, or expense reductions. The enterprise value analysis is performed to determine the value of equity investments and to determine if debt investments are credit impaired. The Valuation Designee may also employ other valuation multiples to determine enterprise value, such as revenues. If debt investments are credit impaired, the Valuation Designee will use the enterprise value analysis or a liquidation basis analysis to determine fair value, which may include evaluating multiple recovery scenarios and weighting the expected outcomes based on their likelihood. For debt investments that are not determined to be credit impaired, the Valuation Designee uses a market interest rate yield analysis to determine fair value.

In addition, for certain debt investments, the Valuation Designee could base its valuation on indicative bid and ask prices provided by an independent third-party pricing service. Bid prices reflect the highest price that we and others could be willing to pay. Ask prices represent the lowest price that we and others may be willing to accept. The Valuation Designee generally uses the midpoint of the bid/ask range as our best estimate of the fair value of such investment.

Due to the inherent uncertainty of determining the fair value of Level 3 investments that do not have a readily available market value, the fair value of the investments could differ significantly from the values that would have been used had a market existed for such investments and could differ materially from the values that could ultimately be received or settled. Further, such investments are generally subject to legal and other restrictions or otherwise are less liquid than publicly traded instruments. 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 such investment had previously been recorded.

Our investments are subject to market risk. Market risk is the potential for changes in the value due to market changes. Market risk is directly impacted by the volatility and liquidity in the markets in which the investments are traded.

TABLE OF CONTENTS

Other Financial Assets and Liabilities

ASC Topic 820 requires disclosure of the fair value of financial instruments for which it is practical to estimate such value. As a result, with the exception of the line item titled “debt” which is reported at cost, all assets and liabilities approximate fair value on the Consolidated Statements of Financial Condition due to their short maturity. The fair value of our revolving credit facilities approximates the carrying value due to their variable interest rates based on selected short term rates.

Revenue Recognition

Our revenue recognition policies are as follows:

Investments and Related Investment Income: Interest income is accrued based upon the outstanding principal amount and contractual interest terms of debt investments. Original issue discount, market discount or premium and certain loan origination or amendment fees that are deemed to be an adjustment to yield (“Loan Origination Fees”) are capitalized and we accrete or amortize such amounts over the life of the loan as interest income (“Discount Amortization”). For investments with contractual PIK interest, which represents contractual interest accrued and added to the principal balance that generally becomes due at maturity, we do not accrue PIK interest if the portfolio company valuation indicates that the PIK interest is not likely to be collectible. In addition, we could generate revenue in the form of amendment, structuring or due diligence fees, fees for providing managerial assistance, administrative agent fees, consulting fees and prepayment premiums on loans that are not deemed to be an adjustment to yield and record these fees as fee income when earned. We record prepayment premiums on loans as fee income. Dividend income on preferred equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. We have certain preferred equity securities in our portfolio that contain a PIK dividend provision that are accrued and recorded as income at the contractual rates, if deemed collectible. The accrued PIK and non-cash dividends are capitalized to the cost basis of the preferred equity security and are generally collected when redeemed by the issuer. Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies. Distributions received from limited liability company, or LLC, and limited partnership, or LP, investments are evaluated to determine if the distribution should be recorded as dividend income or a return of capital. Generally, we will not record distributions from equity investments in LLCs and LPs as dividend income unless there are sufficient accumulated tax-basis earnings and profits in the LLC or LP prior to the distribution. Distributions that are classified as a return of capital are recorded as a reduction in the cost basis of the investment.

We account for investment transactions on a trade-date basis. Realized gains or losses on investments are measured by the difference between the net proceeds from the disposition and the cost basis of investment, without regard to unrealized gains or losses previously recognized. We report changes in fair value of investments from the prior period that is measured at fair value as a component of the “Net change in unrealized appreciation (depreciation) on investment transactions” in our Consolidated Statements of Operations and fluctuations arising from the translation of foreign exchange rates on investments in unrealized appreciation (depreciation) on translation of assets and liabilities in foreign currencies on the Consolidated Statements of Operations.

Non-accrual Investments: Loans may be left on accrual status during the period we are pursuing repayment of the loan. Management reviews all loans that become past due 90 days or more on principal and interest or when there is reasonable doubt that principal or interest will be collected for possible placement on non-accrual status. We generally reverse accrued interest when a loan is placed on non-accrual. Additionally, any original issue discount and market discount are no longer accreted to interest income as of the date the loan is placed on non-accrual status. Interest payments received on non-accrual loans could be recognized as income or applied to principal depending upon management’s judgment. We restore non-accrual loans to accrual status when past due principal and interest is paid and, in our management’s judgment, are likely to remain current. The total fair value of our non-accrual loans was $77.7 million and $27.3 million as of March 31, 2026 and September 30, 2025, respectively. We review all preferred equity securities accruing contractual PIK dividend income to determine if there is reasonable doubt that amortized cost or capitalized PIK and non-cash dividend income will be collected, for possible placement on non-accrual status. When a preferred equity security is placed on non-accrual status, the contractual PIK dividend provision is no longer accrued to dividend income as of the date the preferred equity security is placed on non-accrual status. As of March 31, 2026, there were four preferred equity securities on non-accrual status with a fair value of $40.8 million. As of September 30, 2025, there was one preferred equity security on non-accrual status with a fair value of $0.0 million.

TABLE OF CONTENTS

Income taxes: We have elected to be treated as a RIC under Subchapter M of the Code and operate in a manner so as to qualify for the tax treatment applicable to RICs. In order to be subject to tax as a RIC, we are required to meet certain source of income and asset diversification requirements, as well as timely distribute to our stockholders dividends for U.S. federal income tax purposes of an amount generally at least equal to 90% of investment company taxable income, as defined by the Code and determined without regard to any deduction for dividends paid, for each tax year. We have made and intend to continue to make the requisite distributions to our stockholders, which will generally relieve us from U.S. federal income taxes.

Depending on the level of taxable income earned in a tax year, we could choose to retain taxable income in excess of current year dividend distributions and would distribute such taxable income in the next tax year. We could then be required to incur a 4% excise tax on such income. To the extent that we determine that our estimated current year annual taxable income, determined on a calendar year basis, could exceed estimated current calendar year dividend distributions, we accrue excise tax, if any, on estimated excess taxable income as taxable income is earned. For both three and six months ended March 31, 2026, we did not record any U.S. federal excise tax. For the three months ended March 31, 2025, we did not record any U.S. federal excise tax. For the six months ended March 31, 2025, we recorded a reversal of the accrual for U.S. federal excise tax expense of $0.5 million.

We have consolidated subsidiaries that are subject to U.S. federal and state corporate-level income taxes. For both the three and six months ended March 31, 2026, we did not record any U.S. income taxes and we recorded a net tax benefit of less than $0.1 million for taxable subsidiaries. For the three and six months ended March 31, 2025, we did not record any U.S income taxes and we recorded a net tax benefit of $0.1 million and $0.2 million, respectively, for taxable subsidiaries. As of both March 31, 2026 and September 30, 2025, we recorded a net deferred tax liability, reported within accounts payable and other liabilities on the Consolidated Statement of Financial Condition, of $0.2 million for taxable subsidiaries, primarily due to unrealized appreciation on the investments held at the taxable subsidiaries.

Because federal income tax regulations differ from GAAP, distributions in accordance with tax regulations could differ from net investment income and realized gains recognized for financial reporting purposes. Differences could be permanent or temporary. Permanent differences are reclassified within capital accounts in the financial statements to reflect their tax character. For example, permanent differences in classification could result from the treatment of distributions paid from short-term gains as ordinary income dividends for tax purposes. Temporary differences arise when certain items of income, expense, gain, or loss are recognized at some time in the future.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are subject to financial market risks, including valuation risk and changes in interest rates.

Valuation Risk. Most of our investments will not have a readily available market price. To ensure accurate valuations, our investments are valued at fair value in good faith by the Investment Adviser, as our Valuation Designee, subject to the oversight of our Board based on, among other things, the input of independent third-party valuation firms engaged at the direction of the Valuation Designee, and in accordance with our valuation policy. There is no single standard for determining fair value. As a result, determining fair value requires that judgment be applied to the specific facts and circumstances of each investment while employing a consistently applied valuation process for the investments we hold. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of our investments could fluctuate from period to period, 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 we have recorded it.

Interest Rate Risk. Many of the loans in our portfolio have floating interest rates, and we expect that our loans in the future could also have floating interest rates. These loans are usually based on floating SOFR or another base rate and typically have interest rate reset provisions that adjust applicable interest rates under such loans to current market rates on a daily, monthly, quarterly, semi-annual, or annual basis. The loans that are subject to floating SOFR or another base rate are also typically subject to a minimum base rate, or floor, that we charge on our loans if the current market rates are below the respective floors. As of March 31, 2026 and September 30, 2025, the weighted average floor on loans subject to floating interest rates was 0.77% and 0.78%, respectively. The Class A-1R, and A-2RR 2024 Notes issued in connection with the 2024 Debt Securitization have floating rate interest provisions based on three-month SOFR plus a spread adjustment. The JPM Credit Facility has a floating interest rate provision that, as of March 31, 2026, is primarily based on an applicable base rate (as defined in Note 7 to our consolidated financial statements) plus a spread that ranges from 1.525% to 1.775% plus a spread adjustment of 0.10% on SOFR borrowings. The Adviser Revolver has a floating interest rate provision equal to the mid-term Applicable Federal Rate. We have entered into three interest rate swaps on the 2028 Notes and two interest rate swaps on the 2029 Notes and these swaps have floating rate provisions based on one-month SOFR plus a spread of 3.327%, one-month SOFR plus a spread of 2.835%, floating rate SOFR plus a spread of 1.723%, one-month SOFR plus a spread of 2.444%, and three-month SOFR plus a spread of 2.012%, respectively. We expect that other credit facilities and swaps into which we enter in the future could have floating interest rate provisions.

Assuming that the unaudited interim Consolidated Statement of Financial Condition as of March 31, 2026 was to remain constant and that we took no actions to alter interest rate sensitivity as of such date, the following table shows the annualized impact of hypothetical base rate changes in interest rates.

Change in interest rates Increase (decrease) in<br><br>interest income(1) Increase (decrease) in<br>interest expense Net increase <br>(decrease) in <br> investment income
(In thousands)
Down 200 basis points $ (154,841) $ (75,233) $ (79,608)
Down 150 basis points (117,114) (56,425) (60,689)
Down 100 basis points (78,492) (37,617) (40,875)

Up 100 basis points 78,539 37,617 40,922
Up 150 basis points 117,809 56,425 61,384
Up 200 basis points 157,079 75,233 81,846

(1) Assumes applicable three-month base rate as of March 31, 2026, with the exception of SONIA and Prime that utilize the March 31, 2026 rate.

Although we believe that this analysis is indicative of our sensitivity to interest rate changes as of March 31, 2026, it does not adjust for changes in the credit market, credit quality, the size and composition of the assets in our portfolio and other business developments, including borrowings under the Debt Securitizations, the JPM Credit Facility, the Adviser Revolver, or other borrowings, that could affect net increase in net assets resulting from operations, or net income. Accordingly, we can offer no assurances that actual results would not differ materially from the analysis above.

TABLE OF CONTENTS

We have and, in the future, could hedge against interest rate fluctuations by using standard hedging instruments such as interest rate swaps, futures, options and forward contracts to the limited extent permitted under the 1940 Act and applicable commodities laws. While hedging activities could insulate us against adverse changes in interest rates, they could also limit our ability to participate in the benefits of lower interest rates with respect to the investments in our portfolio with fixed interest rates.

Item 4. Controls and Procedures.

As of March 31, 2026 (the end of the period covered by this report), management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act). Based on that evaluation, our management, including the chief executive officer and chief financial officer, concluded that, at the end of such period, our disclosure controls and procedures were effective and provided reasonable assurance that information required to be disclosed in our periodic SEC filings is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure. Notwithstanding the foregoing, a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that it will detect or uncover failures within the Company to disclose material information otherwise required to be set forth in the Company’s periodic reports.

There has not been any change in our internal controls over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the period covered by this report that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

Item 1: Legal Proceedings.

We, GC Advisors and Golub Capital LLC may, from time to time, be involved in legal and regulatory proceedings arising out of our and their respective operations in the normal course of business or otherwise. While there can be no assurance of the ultimate disposition of any such proceedings, each of us, GC Advisors and Golub Capital LLC do not believe it is currently subject to any material legal proceedings.

Item 1A: Risk Factors.

There have been no material changes during the six months ended March 31, 2026 to the risk factors discussed in Item 1A. Risk Factors in our annual report on Form 10-K for the year ended September 30, 2025.

Item 2: Unregistered Sales of Equity Securities and Use of Proceeds.

None.

Item 3: Defaults Upon Senior Securities.

None.

Item 4: Mine Safety Disclosures.

None.

Item 5: Other Information.

None.

Rule 10b5-1 Trading Plans

During the fiscal quarter ended March 31, 2026, none of our directors or executive officers adopted or terminated any contract, instruction or written plan for the purchase or sale of our securities to satisfy the affirmative defense conditions of Rule 10b5-1(c) or any “non-Rule 10b5-1 trading arrangement.”
