For each, the Company has provided the spread over the applicable index and the weighted average current interest rate in effect as of March 31, 2024. 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, 2024, 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 may not be the applicable index rate outstanding as of March 31, 2024, as the loan may have priced or repriced based on an index rate prior to March 31, 2024.

(4)The fair values of investments were valued using significant unobservable inputs, unless otherwise noted. See Note 7. Fair Value Measurements.

(6)The entire commitment was unfunded as of March 31, 2024. As such, no interest is being earned on this investment. The investment may be subject to an unused facility fee.

(7)Loan was on non-accrual status as of March 31, 2024, meaning that the Company has ceased recognizing interest income on the loan.

+	Denotes that all or a portion of the loan secures the notes offered in the 2022 Debt Securitization (as defined in Note 8).

(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’’), Canadian Bankers Acceptance Rate (‘‘CDOR’’ or ‘‘C’’) or London Interbank Offered Rate (‘‘LIBOR’’ or ‘‘L’’) denominated in U.S. dollars 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, 2023. 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, 2023, 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 may not be the applicable index rate outstanding as of September 30, 2023, as the loan may have priced or repriced based on an index rate prior to September 30, 2023.

(a) Denotes that all or a portion of the contract was indexed to the 180-day LIBOR, which was last quoted on June 30, 2023 at 5.76%.

(b) Denotes that all or a portion of the contract was indexed to the Prime rate, which was 8.50% as of September 30, 2023.

(c) Denotes that all or a portion of the contract was indexed to the 30-day EURIBOR, which was 3.85% as of September 30, 2023.

(d) Denotes that all or a portion of the contract was indexed to the 90-day EURIBOR, which was 3.95% as of September 30, 2023.

(e) Denotes that all or a portion of the contract was indexed to the 180-day EURIBOR, which was 4.13% as of September 30, 2023.

(h) Denotes that all or a portion of the contract was indexed to the 90-day CDOR, which was 5.51% as of September 30, 2023.

(2)For positions with multiple interest rate contracts, the interest rate shown is a weighted average current interest rate in effect as of September 30, 2023.

(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 otherwise noted. See Note 7. Fair Value Measurements.

(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 September 30, 2023. As such, no interest is being earned on this investment. The investment may be subject to an unused facility fee.

(7)Loan was on non-accrual status as of September 30, 2023, meaning that the Company has ceased recognizing interest income on the loan.

(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’’).

Note 1.    Organization

Golub Capital BDC 3, Inc. (“GBDC 3” and, collectively with its consolidated subsidiaries, the “Company”) is an externally managed, closed-end, non-diversified management investment company that was formed on August 1, 2017 and elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (the “1940 Act”), on September 29, 2017. On October 2, 2017, the date of the commencement of operations, the Company entered into subscription agreements (collectively, the “Subscription Agreements”) to sell shares of GBDC 3's common stock in private placements. In addition, for U.S. federal income tax purposes, GBDC 3 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, primarily U.S. middle-market companies. The Company has entered into an investment advisory agreement (the “Investment 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 January 16, 2024, the Company entered into an Agreement and Plan of Merger (the “GBDC 3 Merger Agreement”) with Golub Capital BDC, Inc., a Delaware corporation (“GBDC”), Park Avenue Subsidiary Inc., a Maryland corporation and wholly owned subsidiary of GBDC (“Merger Sub”), the Investment Adviser, and, for certain limited purposes, the Administrator. The GBDC 3 Merger Agreement provides that, subject to the conditions set forth in the GBDC 3 Merger Agreement, Merger Sub will merge with and into the Company, with the Company continuing as the surviving company and as a wholly-owned subsidiary of GBDC and, immediately thereafter, the Company will merge with and into GBDC, with GBDC continuing as the surviving company (the “Proposed Merger”). Refer to Note 13. Pending Merger with Golub Capital BDC, Inc. for discussion of the Proposed Merger.

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, 2023, 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. In

83

Golub Capital BDC 3, Inc. and Subsidiaries

Notes to Consolidated Financial Statements (unaudited)

(In thousands, except shares and per share data)

accordance with ASC Topic 820, the Company has categorized its 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 Company’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 Company 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 Company’s board of directors (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 Company will continue to refine its valuation methodologies. See further description of fair value methodology in Note 7. Fair Value Measurements.

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.

Consolidation: As provided under Regulation S-X and ASC Topic 946, the Company will generally not consolidate its investment in a company other than an investment company subsidiary or a controlled operating company whose business consists of providing services to the Company. Accordingly, the Company consolidated the results of the Company’s wholly-owned subsidiaries, Golub Capital 3 Holdings LLC (“GBDC 3 Holdings”), GBDC 3 Funding LLC (“GBDC 3 Funding”), Golub Capital BDC 3 CLO 1 Depositor LLC (“2021 CLO Depositor”), Golub Capital BDC 3 CLO 1 LLC (“2021 Issuer”), Golub Capital BDC 3 ABS 2022-1 Depositor LLC (“2022 ABS 2022-1 Depositor”), Golub Capital BDC 3 ABS 2022-1 LLC (“2022 Issuer”), Golub Capital BDC 3 CLO 2 Depositor LLC (“2022 CLO 2 Depositor”), Golub Capital BDC 3 CLO 2 LLC (“2022-2 Issuer”), GBDC 3 Holdings Coinvest, Inc., GBDC 3 Holdings ED Coinvest, Inc., GCBH 3 North Haven Stack Buyer Coinvest Inc., GBDC 3 Quick Quack Coinvest LLC, in its consolidated financial statements.

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 GBDC 3 Holdings, GBDC 3 Funding, 2021 Issuer, 2022 Issuer, and the 2022-2 Issuer, 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 3 (or any affiliate of GBDC 3).

Cash and cash equivalents and foreign currencies: Cash and 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 and cash equivalents and restricted foreign currencies:  Restricted cash and 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 and 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.

Notes to Consolidated Financial Statements (unaudited)

(In thousands, except shares and per share data)

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 with 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.

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 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 by counterparty on a net basis, 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 6 for more information regarding the forward currency contracts.

Revenue recognition:

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

Loan origination fees, original issue discount and market discount or premium are capitalized, and the Company accretes or amortizes such amounts over the life of the loan as interest income. For the three and six months ended March 31, 2024, interest income included $2,307 and $5,250, respectively, of accretion of discounts. For the three and six months ended March 31, 2023, interest income included $1,914 and $4,024, respectively, of accretion of discounts. For the three and six months ended March 31, 2024, the Company received loan origination fees of $957 and $3,402, respectively. For the three and six months ended March 31, 2023, the Company received loan origination fees of $2,120 and $4,771, respectively.

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, 2024, investment income included $4,953 and $9,824, respectively, of PIK interest and the Company capitalized PIK interest of $4,555 and $10,258 respectively, into the principal balance of certain debt investments. For the three and six months ended March 31, 2023, investment income included $3,549 and $5,976, respectively, of PIK interest and the Company capitalized PIK interest of $3,819 and $6,147, respectively, into the principal balance of certain debt investments.

(In thousands, except shares and per share data)

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 as fee income when earned. For the three and six months ended March 31, 2024, fee income included $107 and $119, respectively, from non-recurring prepayment premiums, respectively. For the three and six months ended March 31, 2023, fee income included $0 and $35, respectively, from non-recurring prepayment premiums, respectively. All other income is recorded into income when earned.

For the three and six months ended March 31, 2024, the Company received interest and fee income in cash, which excludes capitalized loan origination fees, in the amounts of $70,466 and $139,617, respectively. For the three and six months ended March 31, 2023, the Company received interest and fee income in cash, which excludes capitalized loan origination fees, in the amounts of $26,928 and $76,933, 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, 2024, the Company recognized PIK and non-cash dividend income of $2,537 and $4,993, which were capitalized into the cost basis of certain preferred equity investments. For the three and six months ended March 31, 2024, the Company received no cash payments of accrued and capitalized preferred dividends. For the three and six months ended March 31, 2023, the Company recognized PIK and non-cash dividend income of $2,049 and $3,932, which were capitalized into the cost basis of certain preferred equity investments. For the three and six months ended March 31, 2023, the Company received no 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 amortized cost basis of the investment.

For the three and six months ended March 31, 2024, the Company recorded dividend income received in cash of $3 and $3, respectively, and return of capital distributions received in cash of $43 and $953, respectively. For the three and six months ended March 31, 2023, the Company recorded dividend income received in cash of $2 and $8, respectively, and return of capital distributions received in cash of $294 and $294, 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 loans: A loan can be left on accrual status during the period 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 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 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 $5,092 and $3,637 as of March 31, 2024 and September 30, 2023, respectively.

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 its 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 may 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, 2024, the Company did not record any U.S. federal excise tax. For the three months ended March 31, 2023, the Company recorded a reversal of the accrual for U.S. federal excise tax expense of $25. For the six months ended March 31, 2023, the Company recorded $630 for U.S. federal excise tax expense.

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, 2024. The Company’s tax returns for the 2020 through 2022 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, 2024, $8 was recorded for U.S. income taxes. For the three and six months ended March 31, 2023, the Company did not record any U.S. income taxes.

Dividends and distributions: Dividends and distributions to common stockholders are recorded on the record date. Subject to the discretion of and as determined by the Board, the Company intends to authorize and declare ordinary cash distributions based on a formula approved by the Board on a quarterly basis. 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 have not “opted out” of the DRIP will have their cash distribution automatically reinvested in additional shares of the Company’s common stock, rather than receiving the cash distribution. Shares issued under the DRIP will be issued at a price per share equal to the most recent net asset value (“NAV”) per share as determined by the Board (subject to adjustment to the extent required by Section 23 of the 1940 Act).

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, 2024 and September 30, 2023, the Company had deferred debt issuance costs of $1,776 and $4,038, respectively. These amounts are amortized and included in interest expense 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, 2024 was $958 and $2,262, respectively. Amortization expense for deferred debt issuance costs for the three and six months ended March 31, 2023 was $933 and $1,856, respectively.

Note 3.    Stockholders’ Equity

On December 18, 2023, the Company filed articles of amendment to the Company’s charter to increase the number of authorized shares of stock of the Company from 101,000,000 shares to 111,000,000 shares, consisting of 1,000,000 shares of preferred stock at a par value of $0.001 per share and 110,000,000 shares of common stock at a par value of $0.001 per share. Since the commencement of operations on October 2, 2017, GBDC 3 has entered into Subscription Agreements with several investors, including with affiliates of the Investment Adviser, providing for the private placement of GBDC 3’s common stock. Under the terms of the Subscription Agreements, investors are required to fund drawdowns to purchase GBDC 3’s common stock at a price per share equal to the most recent NAV per share as determined by the Board (subject to adjustment to the extent required by Section 23 of the 1940 Act) up to the amount of their respective capital subscriptions on an as-needed basis as determined by GBDC 3 with a minimum of 10 calendar days prior notice.

Note 4.    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 3. The Board most recently reapproved the Investment Advisory Agreement in May 2024. 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 1.375% 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, unrealized depreciation or appreciation on derivative instruments and cash collateral on deposit for such derivative instruments with custodian, but adjusted to exclude cash and cash equivalents 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

(In thousands, except shares and per share data)

of GBDC 3, 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. For periods ending on or prior to the earlier of (1) the date of pricing of an initial public offering or listing on a national securities exchange of the shares of common stock of GBDC 3 or (2) a sale of all or substantially all of the Company’s assets to, or other liquidity event with, an entity for consideration of publicly listed securities of the acquirer (each, a “Liquidity Event”), the Investment Adviser has irrevocably agreed to waive any base management fee in excess of 1.00% of the fair value of the Company’s average adjusted gross assets as calculated in accordance with the Investment Advisory Agreement as described above.

The base management fee incurred for the three and six months ended March 31, 2024 was $9,258 and $18,532, respectively, and the base management fee irrevocably waived by the Investment Adviser was $2,525 and $5,054, respectively. The base management fee incurred for the three and six months ended March 31, 2023 was $8,343 and $16,675, respectively, and the base management fee irrevocably waived by the Investment Adviser was $2,276 and $4,548, respectively.

The Incentive Fee consists of three parts: the income component (the “Income Incentive Fee”), the capital gains component (the “Capital Gain Incentive Fee”) and the subordinated liquidation incentive component (the “Subordinated Liquidation Incentive Fee” and, together with the Income Incentive Fee and the Capital Gain Incentive Fee, the “Incentive Fee”).

The Income Incentive Fee is calculated quarterly in arrears based on Pre-Incentive Fee Net Investment Income for the immediately preceding calendar quarter. “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.

Pre-Incentive Fee Net Investment Income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. 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 Income 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 Income Incentive Fee would cause the Company to pay Income Incentive Fees and Capital Gain Incentive Fees on a cumulative basis that exceed the Incentive Fee Cap described below.

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 1.5% 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 the Company’s Pre-Incentive Fee Net Investment Income and make it easier for the Investment Adviser to surpass the fixed hurdle rate and receive an Income Incentive Fee.

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, securitization-related assets, unrealized depreciation or appreciation on derivative instruments and cash collateral on deposit with custodian) used to calculate the base management fee.

The Company calculates 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;

•50.0% of 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 Investment Adviser pursuant to the Income Incentive Fee equal 20.0% of the Pre-Incentive Fee Net Investment Income that exceeds the hurdle rate as if a hurdle rate did not apply. This portion of Pre-Incentive Fee Net Investment Income that exceeds the hurdle rate is referred to as the ‘‘catch-up’’ provision; and

•20.0% of the amount of Pre-Incentive Fee Net Investment Income, if any, that exceeds the catch-up provision in any calendar quarter.

The sum of these calculations yields the Income Incentive Fee. This amount is appropriately adjusted for any share issuances or repurchases during the quarter.

For the three and six months ended March 31, 2024, the Income Incentive Fee incurred was $9,114 and $18,474, respectively. For the three and six months ended March 31, 2023, the Income Incentive Fee incurred was $7,513 and $14,343, respectively.

For periods ending on or prior to the date of the closing of a Liquidity Event, the Investment Adviser has agreed to irrevocably waive that portion of the Income Incentive Fee calculated under the Investment Advisory Agreement in amounts in excess of the following amounts (computed on a quarterly basis, in arrears):

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

•50.0% 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 the amount payable to the Investment Adviser equals to 15.0% of the 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 that exceeds the hurdle rate is referred to as the “catch-up” provision; 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.

For the three and six months ended March 31, 2024, the Income Incentive Fee irrevocably waived by the Investment Adviser was $2,278 and $4,618, respectively. For the three and six months ended March 31, 2023, the Income Incentive Fee irrevocably waived by the Investment Adviser was $1,878 and $3,586, respectively.

The second part of the Incentive Fee, the Capital Gain Incentive Fee, equals (a) 20.0% 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, 2017, 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 September 29, 2017, 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 as of the date of calculation, 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.

91

Golub Capital BDC 3, Inc. and Subsidiaries

Notes to Consolidated Financial Statements (unaudited)

(In thousands, except shares and per share data)

•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.

The Capital Gain Incentive Fee is calculated on a cumulative basis from September 29, 2017 through the end of each calendar year or termination of the Investment Advisory Agreement. For periods ending on or prior to the date of the closing of a Liquidity Event, the Investment Adviser has agreed to irrevocably waive that portion of the Capital Gain Incentive Fee, calculated as described above, in excess of 15.0% of the Capital Gain Incentive Fee Base, provided that any amounts so waived shall be deemed paid to the Investment Adviser for purposes of determining the Capital Gain Incentive Fee payable after the closing of a public offering or listing.

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, 2024 and 2023, the Company did not accrue a Capital Gain Incentive Fee. As of both March 31, 2024 and September 30, 2023, 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. The Company has not paid any Capital Gain Incentive Fees calculated in accordance with the Investment Advisory Agreement on or prior to March 31, 2024.

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 15.0% prior to a Liquidity Event (20.0% following a Liquidity Event) 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, 2024, 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 both March 31, 2024 and September 30, 2023, there was no cumulative accrual of capital gain incentive fee under GAAP included in management and incentive fees payable on the Consolidated Statements of Financial Condition.

The third part of the Incentive Fee, the Subordinated Liquidation Incentive Fee, equals 15.0% of the net proceeds from a liquidation of the Company in excess of adjusted capital, as calculated immediately prior to liquidation. For purposes of this calculation, (a) ‘‘liquidation’’ includes any merger of the Company with another entity or the acquisition of all or substantially all of the shares of the Company’s common stock in a single or series of related transactions and (b) ‘‘adjusted capital’’ means the net asset value of the Company calculated immediately prior to liquidation in accordance with GAAP less unrealized capital appreciation that would have been subject to the Capital Gain Incentive Fee had capital gain been recognized on the transfer of such assets in the liquidation.

The Investment Advisory Agreement provides that no Subordinated Liquidation Incentive Fee shall be payable for any liquidation that occurs more than six months after the date of an initial public offering of the Company’s common stock or a listing of the Company’s common stock on a national securities exchange. For periods prior to the date of the closing of a Liquidity Event, the Investment Adviser has agreed to waive the Subordinated

(In thousands, except shares and per share data)

Liquidation Incentive Fee. On January 16, 2024, the Investment Adviser agreed to irrevocably waive any Subordinated Liquidation Incentive Fee that would otherwise be payable in connection with the transactions contemplated by the GBDC 3 Merger Agreement.

The Company has structured the calculation of the Incentive Fee to include a fee limitation such that the Income Incentive Fee and the Capital Gain Incentive Fee will not be paid at any time if, after such payment, the cumulative Income Incentive Fees and Capital Gain Incentive Fees paid to date would exceed an incentive fee cap (the ‘‘Incentive Fee Cap’’). For periods ending on or prior to the date of the closing of a Liquidity Event, the Incentive Fee Cap in any quarter is equal to the difference between (a) 15.0% of Cumulative Pre-Incentive Fee Net Income and (b) cumulative incentive fees of any kind paid to the Investment Adviser by the Company since September 29, 2017. For periods beginning after the date of the closing of a Liquidity Event, the Incentive Fee Cap in any quarter will be equal to the difference, if positive, between (a) the sum of (i) 20.0% of Cumulative Pre-Incentive Fee Net Income for the period beginning on the date immediately following the closing of a Liquidity Event and (ii) 15.0% of Cumulative Pre-Incentive Fee Net Income for the period from September 29, 2017 and ending on the date of the closing of a Liquidity Event and (b) cumulative Income Incentive Fees and Capital Gain Incentive Fees paid to the Investment Adviser by the Company from September 29, 2017.

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. ‘‘Cumulative Pre-Incentive Fee Net Income’’ is equal to the sum of (a) Pre-Incentive Fee Net Investment Income for each period since September 29, 2017 and (b) cumulative aggregate realized capital gains, cumulative aggregate realized capital losses, cumulative aggregate unrealized capital depreciation and cumulative aggregate unrealized capital appreciation since September 29, 2017.

The sum of the Income Incentive Fee, the Capital Gain Incentive Fee and the Subordinated Liquidation Incentive Fee is the Incentive Fee. Prior to the closing of a Liquidity Event, the Company will deposit one-third of each Income Incentive Fee and Capital Gain Incentive Fee payment into an escrow account (the “Escrow Account”) to be administered by U.S. Bank National Association (the “Escrow Agent”). Assets in the Escrow Account will be held by the Escrow Agent until the closing of a Liquidity Event at which time the Escrow Agent will release the assets to the Investment Adviser. If no Liquidity Event occurs prior to October 2, 2023, the Escrow Agent will return all assets in the Escrow Account to the Company for the benefit of the stockholders. On October 2, 2023, the Escrow Agent returned $14,875 of deposits held in the Escrow Account to the Company for the benefit of shareholders in accordance with the Investment Advisory Agreement.

On December 7, 2023, GC Advisors unilaterally agreed to extend the term of the incentive fee payment escrow under the terms of the Investment Advisory Agreement (the “Escrow Waiver Letter”). In accordance with the Escrow Waiver Letter, prior to the closing of a Liquidity Event, the Company will deposit one-third of each Income Incentive Fee and Capital Gain Incentive Fee payment into an escrow account (the “ New Escrow Account”) to be administered by UMB Bank, National Association (the “ New Escrow Agent”). Assets in the New Escrow Account will be held by the New Escrow Agent until the closing of a Liquidity Event at which time the New Escrow Agent will release the assets to the Investment Adviser. If no Liquidity Event occurs prior to October 2, 2025, the New Escrow Agent will return all assets in the New Escrow Account to the Company for the benefit of the stockholders. For the six months ended March 31, 2024, the Company deposited $4,533 into the New Escrow Account.

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.

As of March 31, 2024 and September 30, 2023, included in accounts payable and other liabilities is $1,027 and $959, as of March 31, 2024 and September 30, 2023, respectively, for accrued allocated shared services under the Administration Agreement.

Other related party transactions: The Administrator pays for certain unaffiliated third-party expenses incurred by the Company. Such expenses include postage, printing, office supplies, rating agency fees and professional fees. These expenses are not marked-up and represent the same amount the Company would have paid had the Company paid the expenses directly. These expenses are subsequently reimbursed in cash.

Total expenses reimbursed to the Administrator during the three and six months ended March 31, 2024 were $688 and $1,556, respectively. Total expenses reimbursed to the Administrator during the three and six months ended March 31, 2023 were $705 and $1,359, respectively. As of March 31, 2024 and September 30, 2023, included in accounts payable and other liabilities were $742 and $868, respectively, for reimbursable expenses that were paid by the Administrator on behalf of the Company.

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 its derivative counterparty, Macquarie Bank Limited (“Macquarie”). The ISDA Master Agreement is a bilateral agreement between the Company and Macquarie that governs over the counter (“OTC”) derivatives, including forward currency contracts, and contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. The provisions of the ISDA Master Agreement permit 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 Macquarie, if any, is included in the Consolidated Statements of Financial Condition as cash collateral held at broker for forward currency contracts or cash collateral received from broker for forward currency contracts. 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 forward currency contracts on the consolidated financial statements of the Company including: the fair value of derivatives by risk category, 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, 2024 and September 30, 2023:

As of March 31, 2024

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 may 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 7. 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 management 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. The Company’s fair value analysis 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 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 Company’s 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. The Company 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, 2024 and 2023. The following section describes the valuation techniques used by the Company 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 Board, based on input of management, the audit committee and independent valuation firms that have been engaged at the direction of the Board to assist in the valuation of each portfolio investment without a readily available market quotation at least once during a trailing twelve-month period under a valuation policy and a consistently applied valuation process. This valuation process is conducted at the end of each fiscal quarter, with approximately 25% (based on the number of portfolio companies) of the Company’s valuations of debt and equity investments without readily available market quotations subject to review by an independent valuation firm. All investments as of both March 31, 2024 and September 30, 2023, were valued using Level 3 inputs. As of both March 31, 2024 and September 30, 2023, all money market funds included in cash and cash equivalents and restricted cash and cash equivalents were valued using Level 1 inputs and all forward currency contracts were valued using Level 2 inputs.

When determining fair value of Level 3 debt and equity investments, the Company 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. If debt investments are credit impaired, the Company will use the enterprise value analysis or a liquidation basis analysis to determine fair value. For debt investments that are not determined to be credit impaired, the Company uses a market interest rate yield analysis to determine fair value.

In addition, for certain debt investments, the Company 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 may be willing to pay. Ask prices represent the lowest price that the Company and others may be willing to accept. The Company 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 may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that 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.

(5)The Company valued $128,223 and $12,953 of equity investments using EBITDA and revenue multiples, respectively.

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 Company.

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 Company uses EBITDA multiples and, to a lesser extent, revenue multiples on its 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 Company 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 may 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. Fair value of the Company’s debt is estimated using Level 3 inputs by discounting remaining payments using applicable implied market rates.

The following are the carrying values and fair values of the Company’s debt as of March 31, 2024 and September 30, 2023:

	As of March 31, 2024				As of September 30, 2023
	Carrying Value		Fair Value		Carrying Value		Fair Value
Debt	$	1,260,292	$	1,259,089	$	1,240,900	$	1,235,197

As of March 31, 2024, the DB Credit Facility bears interest at the applicable base rate plus 2.55% per annum during the Revolving Period and 3.05% after the Revolving Period. The base rate under the DB Credit Facility is (i) the three-month Canadian Dollar Offered Rate with respect to any advances denominated in Canadian dollars, (ii) the three-month EURIBOR with respect to any advances denominated in euros, (iii) the three-month Bank Bill Swap Rate with respect to any advances denominated in Australian dollars, (iv) the daily simple Sterling Overnight Index Average with respect to any advances denominated U.K. pound sterling and (v) the three-month term SOFR with respect to any other advances. A syndication/agent fee is payable to the facility agent each quarter and is calculated based on the aggregate commitments outstanding each day during the preceding collection period at a rate of 1/360 of 0.25% of the aggregate commitments on each day. In addition, a non-usage fee of 0.25% per annum is payable on the undrawn amount under the DB Credit Facility, and, during the Revolving Period, an additional fee based on unfunded commitments of the lenders may be payable if borrowings under the DB Credit Facility do not exceed a minimum utilization percentage threshold. A prepayment fee would be payable in the event of any permanent reduction in commitments of the DB Credit Facility in the amount of 0.50% or 0.25% of the amount of the reduction during the first or second year after the Effective Date, respectively.

Note 9. Commitments and Contingencies

Commitments: As of March 31, 2024, the Company had outstanding commitments to fund investments totaling $141,702, including $23,351 of commitments on undrawn revolvers. As of September 30, 2023, the Company had outstanding commitments to fund investments totaling $176,001, including $22,517 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 may 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 6. Forward Currency Contracts” for outstanding forward currency contracts as of March 31, 2024 and September 30, 2023. 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 may not achieve the anticipated benefits of the derivative instruments and may 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 may 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.

Note 13. Pending Merger with Golub Capital BDC, Inc.

Merger Agreement with Golub Capital BDC, Inc. (the “Proposed Merger”)

On January 16, 2024, the Company entered into the GBDC 3 Merger Agreement with GBDC, Merger Sub, the Investment Adviser, and, for certain limited purposes, the Administrator. The GBDC 3 Merger Agreement provides that, subject to the conditions set forth in the GBDC 3 Merger Agreement, Merger Sub will merge with and into the Company, with the Company continuing as the surviving company and as a wholly-owned subsidiary of GBDC and, immediately thereafter, the Company will merge with and into GBDC, with GBDC continuing as the surviving company. The parties to the GBDC 3 Merger Agreement intend the Proposed Merger to be treated as a “reorganization” within the meaning of Section 368(a) of the Code.

In the Proposed Merger, each share of the Company’s common stock issued and outstanding immediately prior to the effective time of the Proposed Merger, except for shares, if any, owned by GBDC or any of its consolidated subsidiaries (the “Cancelled Shares), will be converted into the right to receive a number of GBDC’s common stock equal to the Exchange Ratio (as defined below) in connection with the closing of the Proposed Merger.

Under the terms of the GBDC 3 Merger Agreement, the “Exchange Ratio” will be determined as of a mutually agreed date (such date, the “Determination Date”) no earlier than 48 hours (excluding Sundays and holidays) prior to the effective date of the Proposed Merger and based on (i) the NAV per share of GBDC and GBDC 3 (the “GBDC Per Share NAV” and the “GBDC 3 Per Share NAV”, respectively) and (ii) the closing price per share of GBDC’s common stock on the Nasdaq on either the Determination Date or, if the Nasdaq is closed on the Determination Date, the most recent trading day prior to the Determination Date (the “GBDC Common Stock Price”). The Exchange Ratio will be calculated as follows:

(i) if the GBDC Common Stock Price is greater than the GBDC Per Share NAV, then the Exchange Ratio shall be the quotient (rounded to the fourth nearest decimal) of: (A) the amount equal to (x) GBDC 3 Per Share NAV multiplied by (y) the sum of (a) one (1) and (b) the GBDC 3 Share of GBDC Premium (as defined below); divided by (B) the GBDC Common Stock Price; provided, that, the amount set forth in sub-clause (y) for the purposes of the calculation shall not be greater than, and shall be subject to a cap of, 1.03. “GBDC 3 Share of GBDC Premium” means fifty percent (50%) multiplied by the difference between

117

Golub Capital BDC 3, Inc. and Subsidiaries

Notes to Consolidated Financial Statements (unaudited)

(In thousands, except shares and per share data)

(A) the quotient of (x) GBDC Common Stock Price; divided by (y) GBDC Per Share NAV and (B) one (1); or

(ii) if the GBDC Common Stock Price is equal to or lesser than GBDC Per Share NAV, then the Exchange Ratio will be the quotient (rounded to the fourth nearest decimal) of: (A) the GBDC 3 Per Share NAV, divided by (B) the GBDC Per Share NAV.

The consummation of the Proposed Merger, which is currently anticipated to occur during the first half of calendar year 2024, is subject to certain closing conditions, including (1) requisite approvals of the Company’s stockholders and GBDC’s stockholders, (2) the absence of certain legal impediments to the consummation of the Proposed Merger, (3) effectiveness of the registration statement for GBDC’s common stock to be issued as consideration in the Proposed Merger, (4) subject to certain exceptions, the accuracy of the representations and warranties and compliance with the covenants of each party to the GBDC 3 Merger Agreement, and (5) required regulatory approvals (including expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended).

Note 14. Subsequent Events

In preparing these consolidated financial statements, the Company has evaluated events and transactions for potential recognition or disclosure through the date of issuance. There are no subsequent events to disclose except for the following:

On April 9, 2024, the Company entered into an amendment to the DB Credit Facility to, among other things, amend the interest rate at which borrowings are made to the applicable base rate plus 2.30% during the Revolving Period, and 2.80% after the Revolving Period, extend the Revolving Period to April 10, 2025 and extend the maturity date to the earliest of (i) April 10, 2028, (ii) the date on which the Company ceases to exist or (iii) the occurrence of the event of default.

On February 2, 2024, the Company’s board of directors declared distributions to holders of record as set forth in the table below:

Record Date	Payment Date	Amount Per Share
April 19, 2024	May 29, 20241	In an amount (if positive) such that the NAV of the Company as of April 30, 2024 on a pro forma basis after giving effect to the net increase in net assets resulting from operations earned by the Company (if positive) as determined in accordance with GAAP for the period April 1, 2024 through April 30, 2024 and the payment of this distribution is $14.70 per share

1 On April 19, 2024, the Company’s board of directors accelerated the payment date to May 29, 2024, for the previously declared April 2024 monthly distribution to stockholders of record as of April 19, 2024.

This quarterly report on Form 10-Q contains statistics and other data that have been obtained from or compiled from information made available by third-party service providers.

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. We were formed in August 2017 and commenced operations on October 2, 2017.

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 $65.0 billion in capital under management as of January 1, 2024, (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 2024. Under an administration 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 $5.0 million to $45.0 million of capital, on average, in the securities of U.S. middle-market

120

companies. We also selectively invest more than $45.0 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 may increase our risk of losing part or all of our investment.

As of March 31, 2024 and September 30, 2023, our portfolio at fair value was comprised of the following:

	As of March 31, 2024				As of September 30, 2023

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, 2024 and September 30, 2023, one stop loans included $347.6 million and $326.0 million, respectively, of recurring revenue loans at fair value.

As of March 31, 2024 and September 30, 2023, we had debt and equity investments in 319 and 291 portfolio companies, respectively.

The following table shows the weighted average income yield and weighted average investment income yield of our earning portfolio company investments, which represented nearly 100% of our debt investments, as well as the annualized total return based on our average net asset value, in each case for the three months ended March 31, 2024 and December 31, 2023 and the six months ended March 31, 2024 and March 31, 2023:

	Three months ended		Six months ended

As of March 31, 2024, GBDC 3 has earned an inception-to-date internal rate of return, or IRR, of 9.3% for stockholders taken as a whole. An individual stockholder’s IRR may vary based on the timing of their capital transactions. For the six months ended March 31, 2024 and 2023, GBDC 3 earned a fiscal year-to-date IRR of 20.2% and 7.2%, respectively, for stockholders taken as a whole. The IRR is the annualized effective compound rate of return that brings a series of cash flows to the current value of the cash invested. The IRR was computed based on the actual dates of cash inflows (share issuances, including share issuances through the DRIP), outflows (capital distributions), the stockholders' net asset value, or NAV, at the end of the period and distributions declared and payable at the end of the period (residual value of the stockholders’ NAV and distributions payable as of each measurement date).

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.

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:

•reimbursement to GC Advisors of organizational and offering expenses up to an aggregate amount of $0.7 million;

•calculating our 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;

•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;

122

•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.

GC Advisors, as collateral manager for our indirect, wholly owned, consolidated subsidiary, Golub Capital BDC 3 CLO 1 LLC, or the 2021 Issuer, under a collateral management agreement, or the 2021 Collateral Management Agreement, is entitled to receive an annual fee in an amount equal to 0.35% of the principal balance of the portfolio loans held by the 2021 Issuer at the beginning of the collection period relating to each payment date, which is payable in arrears on each payment date. Under the 2021 Collateral Management Agreement, the term “collection period” refers to the period commencing on the tenth business day prior to the preceding payment date and ending on (but excluding) the tenth business day prior to such payment date.

GC Advisors, as collateral manager for our indirect, wholly owned, consolidated subsidiary, Golub Capital BDC 3 ABS 2022-1 LLC, or the 2022 Issuer, under a collateral management agreement, or the 2022-2 Collateral Management Agreement, is entitled to receive an annual fee in an amount equal to 0.35% of the principal balance of the portfolio loans held by the 2022 Issuer at the beginning of the collection period relating to each payment date, which is payable in arrears on each payment date. Under the 2022 Collateral Management Agreement, the term “collection period” relating to any payment date, refers to the period commencing on the tenth business day prior to the preceding payment date and ending on (but excluding) the tenth business day prior to such payment date.

GC Advisors, as collateral manager for our indirect, wholly owned, consolidated subsidiary, Golub Capital BDC 3 CLO 2 LLC, or the 2022-2 Issuer, under a collateral management agreement, or the 2022-2 Collateral Management Agreement, is entitled to receive an annual fee in an amount equal to 0.35% of the principal balance of the portfolio loans held by the 2022-2 Issuer at the beginning of the collection period relating to each payment date, which is payable in arrears on each payment date. Under the 2022-2 Collateral Management Agreement, the term “collection period” refers to the period commencing on the tenth business day prior to the preceding payment date and ending on (but excluding) the tenth business day prior to such payment date.

Collateral management fees are paid directly by the 2021 Issuer, the 2022 Issuer and the 2022-2 Issuer and are offset against the management fees payable under the Investment Advisory Agreement. In addition, the 2021 Issuer and the 2022 Issuer paid Deutsche Bank AG, New York Branch, structuring and placement fees for its services in connection with the structuring of the 2021 Debt Securitization and the 2022 Debt Securitization (as defined in Note 8 of our consolidated financial statements). The 2022-2 Issuer paid GreensLedge Capital Markets LLC and KeyBanc Capital Markets Inc. structuring and placement fees for its services in connection with the structuring of the 2022-2 Debt Securitization (as defined in Note 8 of our consolidated financial statements). Term debt securitizations, are also known as collateralized loan obligations, or CLOs. Term debt securitization and asset backed securitizations are a form of secured financing incurred by us, which are consolidated by us and subject to our overall asset coverage requirement. The 2021 Issuer, the 2022 Issuer and the 2022-2 Issuer also agreed to pay ongoing administrative expenses to the trustee, collateral manager, independent accountants, legal counsel, rating agencies and independent managers in connection with developing and maintaining reports, and providing required services in connection with

123

the administration of the 2021 Debt Securitization, 2022 Debt Securitization and 2022-2 Debt Securitization, respectively.

We believe that these administrative expenses approximate the amount of ongoing fees and expenses that we would be required to pay in connection with a traditional secured credit facility. Our common stockholders indirectly bear all of these expenses.

Pending Merger with Golub Capital BDC, Inc.: On January 16, 2024, we entered into an Agreement and Plan of Merger (the “GBDC 3 Merger Agreement”) with Golub Capital BDC, Inc., a Maryland corporation (“GBDC”), Park Avenue Subsidiary Inc., a Maryland corporation and wholly owned subsidiary of GBDC (“Merger Sub”), GC Advisers, and, for certain limited purposes, the Administrator. The GBDC 3 Merger Agreement provides that, subject to the conditions set forth in the GBDC 3 Merger Agreement, Merger Sub will merge with and into us, with us continuing as the surviving company and as a wholly-owned subsidiary of GBDC, and, immediately thereafter, we will merge with and into GBDC, with GBDC continuing as the surviving company. The parties to the GBDC 3 Merger Agreement intend the Merger to be treated as a “reorganization” within the meaning of Section 368(a) of the Code.

On April 12, 2024, we filed an amended registration statement on Form N-14, which included a joint proxy statement of us and GBDC and a prospectus of GBDC. The registration statement on Form N-14 was declared effective by the SEC on April 15, 2024. Special meetings for each of our and GBDC’s stockholders are scheduled for May 29, 2024 to vote on the matters described in the joint proxy statement as required by the GBDC 3 Merger Agreement.

Recent Developments

On April 9, 2024, we entered into an amendment on the DB Credit Facility (as defined in Note 8 of our consolidated financial statements) to, among other things, amend the interest rate at which borrowings are made to the applicable base rate plus 2.30% during the Revolving Period (as defined in Note 8 of our consolidated financial statements), and 2.80% after the Revolving Period, extend the Revolving Period to April 10, 2025 and extend the maturity date to the earliest of (i) April 10, 2028, (ii) the date on which we cease to exist or (iii) the occurrence of an event of default.

On February 2, 2024, our board of directors declared distributions to holders of record as set forth in the table below:

Record Date	Payment Date	Amount Per Share
April 19, 2024	May 29, 20241	In an amount (if positive) such that our NAV as of April 30, 2024 on a pro forma basis after giving effect to the net increase in net assets resulting from operations earned by us (if positive) as determined in accordance with GAAP for the period April 1, 2024 through April 30, 2024 and the payment of this distribution is $14.70 per share

Consolidated Results of Operations

In addition to our analysis of the year-to-date reporting period compared to the year-to-date prior period, 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, 2024 and December 31, 2023 and the six months ended March 31, 2024 and March 31, 2023 are as follows:

1 On April 19, 2024, our board of directors accelerated the payment date to May 29, 2024, for the previously declared April 2024 monthly distribution to stockholders of record as of April 19, 2024.

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. In addition, as we have continued to deploy capital, we have experienced significant growth in total assets, total liabilities and net assets. As a result, quarterly and year-to-date comparisons of operating results may not be meaningful.

Investment Income

Investment income decreased from the three months ended December 31, 2023 to the three months ended March 31, 2024 by $0.9 million, primarily due to a decrease in accretion income resulting from decreased payoffs of portfolio company investments coupled with a modest decrease in interest income due to the one-time recognition of interest income associated with a portfolio company investment amendment during the three months ended December 31, 2023.

Investment income increased from the six months ended March 31, 2023 to the six months ended March 31, 2024 by $34.2 million, primarily due to an increase in interest and payment-in-kind (“PIK”) interest income due to rising interest base rates and an increase in the average earning debt investments balance of $229.7 million coupled with an increase in non-cash dividend income and an increase in accretion income resulting from increased payoffs of portfolio company investments.

The annualized income yield by debt security type for the three months ended March 31, 2024, December 31, 2023 and the six months ended March 31, 2024 and March 31, 2023 are as follows:

	Three months ended		Six months ended
	March 31, 2024	December 31, 2023	March 31, 2024	March 31, 2023
Senior secured	10.9%	11.2%	11.1%	9.6%
One stop	11.9%	12.0%	12.0%	10.5%
Second lien	14.2%	13.7%	14.2%	12.7%
Subordinated debt	14.2%	14.8%	14.3%	15.5%

125

The income yield on senior secured loans decreased for the three months ended March 31, 2024 as compared to the three months ended December 31, 2023, primarily due to the one-time recognition of interest income associated with a portfolio company investment amendment during the three months ended December 31, 2023. The income yield on one stop loans remained relatively flat for the three months ended March 31, 2024 as compared to the three months ended December 31, 2023. Income yields on senior secured and one stop loans increased for the six months ended March 31, 2024 as compared to the six months ended March 31, 2023, primarily due to rising interest base rates. Our loan portfolio is partially insulated from a drop in floating interest rates as 97.3% of the loan portfolio at fair value is subject to an interest rate floor. As of both March 31, 2024 and December 31, 2023, the weighted average base rate floor of our loans was 0.79%.

As of March 31, 2024, we have second lien investments in three portfolio companies and subordinated debt investments in five 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.

For additional details on investment yields and asset mix, refer to the “Liquidity and Capital Resources - Portfolio Composition, Investment Activity and Yield” section below.

Expenses

The following table summarizes our expenses for the three months ended March 31, 2024 and December 31, 2023 and the six months ended March 31, 2024 and March 31, 2023:

	Three months ended				Variances		Six months ended				Variances

Interest Expense

Interest and other debt financing expenses, including amortization of debt issuance costs, decreased by $0.3 million from the three months ended December 31, 2023 to the three months ended March 31, 2024, primarily due to a decrease in amortization of debt issuance costs as the fees associated with the 2022 Debt Securitization and the DB Credit Facility were fully amortized during the quarter.

Interest and other debt financing expenses, including amortization of debt issuance costs, increased by $11.8 million from the six months ended March 31, 2023 to the six months ended March 31, 2024, primarily due to an increase in average debt outstanding of $69.8 million as well as rising interest base rates on borrowings from our floating rate debt facilities. For more information about our outstanding borrowings for the three and six months ended March 31, 2024 and 2023, including the terms thereof, see “Note 8. Borrowings” in the notes to our consolidated financial statements and the “Liquidity and Capital Resources” section below.

126

For the three months ended March 31, 2024 and December 31, 2023, the effective annualized average interest rate, which includes amortization of debt financing costs and non-usage facility fees, on our total debt was 8.2% and 8.4%, respectively. For the six months ended March 31, 2024 and 2023, the effective annualized average stated interest rate, which includes amortization of debt financing costs and non-usage facility fees, on our total debt was 8.3% and 6.8%, respectively. The effective annualized average interest rate decreased from the three months ended December 31, 2023 to the three months ended March 31, 2024 primarily due to a decrease in amortization of deferred debt issuance costs as the fees associated with the 2022 Debt Securitization and DB Credit Facility were fully amortized. The effective annualized interest rates increased for the six months ended March 31, 2023 to the six months ended March 31, 2024 primarily due to rising base interest rates on our floating rate debt facilities.

Management Fees

The base management fee, net of waiver, remained relatively flat consistent with the relatively stable amount of average adjusted assets for the three months ended December 31, 2023 to the three months ended March 31, 2024. The base management fee, net of waiver, increased as a result of an increase in average gross assets for the six months ended March 31, 2023 to the six months ended March 31, 2024.

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, net of waiver, decreased by $0.2 million from the three months ended December 31, 2023 to the three months ended March 31, 2024, primarily as a result of a decrease in Pre-Incentive Fee Net Investment Income (as defined in Note 4 to our consolidated financial statements) and a lower rate of return on the value of our net assets driven by a decrease in interest and accretion income. The Income Incentive Fee, net of waiver, increased by $3.1 million from the six months ended March 31, 2023 to the six months ended March 31, 2024, primarily as a result of an increase in Pre-Incentive Fee Net Investment Income and a greater rate of return on the value of our net assets driven by net funds growth, the impact of rising interest base rates and an increase in accretion income resulting from increased payoffs of portfolio company investments.

The Income Incentive Fee as a percentage of Pre-Incentive Fee Net Investment Income, net of waiver, was 15.0% for both the three and six months ended March 31, 2024 and 2023.

During the three months ended December 31, 2023, we recognized $14.9 million of reimbursement of prior period incentive fee payment deposits held in the Escrow Account that was returned to us on October 2, 2023 for the benefit of shareholders in accordance with the Investment Advisory Agreement.

As of March 31, 2024 and September 30, 2023, 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, 2024 and September 30, 2023, there was no capital gain incentive fee accrual calculated in accordance with GAAP. For the three and six months ended March 31, 2024 and 2023, there was no accrual of capital gain incentive fee under GAAP.

Any payment due under the terms of the Investment Advisory Agreement is calculated in arrears at the end of each calendar year. As of March 31, 2024 and September 30, 2023, no Capital Gain Incentive Fees have been payable as calculated under the Investment Advisory Agreement.

127

Professional Fees, Administrative Service Fee and General and Administrative Expenses

In total, professional fees, the administrative service fee, and general and administrative expenses increased by $0.6 million from the three months ended December 31, 2023 to the three months ended March 31, 2024 primarily due to higher professional fees.

In total, professional fees, the administrative service fee and general and administrative expenses increased by $1.0 million from the six months ended March 31, 2023 to the six months ended March 31, 2024 primarily due to an increase in professional fees and 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, 2024 and December 31, 2023 were $0.7 million and $0.9 million, respectively. Total expenses reimbursed to the Administrator during the six months ended March 31, 2024 and March 31, 2023 were $1.6 million and $1.4 million, respectively.

As of March 31, 2024 and September 30, 2023, included in accounts payable and accrued expenses were $0.7 million and $0.9 million, respectively, of expenses paid on behalf of us by the Administrator.

During the three months ended March 31, 2024, we had a net realized gain on investment transactions of $0.2 million, primarily due to a realized gain on the sale of a portfolio company equity investment. During the three months ended December 31, 2023, we had a net realized gain on investment transactions of less than $0.1 million, primarily driven by realized gains from translation of foreign currency amounts and transactions into U.S. dollars that were, partially offset by a realized loss on the partial redemption of an equity investment.

During the six months ended March 31, 2024, we had a net realized gain on investment transactions of $0.2 million, primarily due to realized gains on the sale of equity investments in multiple portfolio companies. During the six months ended March 31, 2023, we had a net realized gain on investment transactions of $3.8 million, primarily due to realized gains on the sale of equity investments in multiple portfolio companies and gains recognized on the settlement of forward currency contracts.

For the three months ended March 31, 2024, we had $20.0 million in unrealized appreciation on 172 portfolio company investments, which was offset by $6.3 million in unrealized depreciation on 156 portfolio company investments. For the three months ended December 31, 2023, we had $12.8 million in unrealized appreciation on 117 portfolio company investments, which was offset by $17.2 million in unrealized depreciation on 197 portfolio company investments.

Unrealized appreciation for the three months ended March 31, 2024 primarily resulted from strong credit performance in our portfolio. Unrealized appreciation for the three months ended December 31, 2023 primarily resulted from the improved performance of certain portfolio companies and the reversal of unrealized depreciation due to spread tightening in the market during the second half of calendar year 2023. Unrealized depreciation for the three months ended March 31, 2024 and December 31, 2023 primarily resulted from isolated deterioration in the credit performance of a small number of portfolio companies.

For the six months ended March 31, 2024, we had $27.6 million in unrealized appreciation on 187 portfolio company investments, which was offset by $18.4 million in unrealized depreciation on 141 portfolio company investments. For the six months ended March 31, 2023, we had $11.3 million in unrealized appreciation on 101 portfolio company investments, which was offset by $31.2 million in unrealized depreciation on 186 portfolio company investments.

Unrealized appreciation for the six months ended March 31, 2024 primarily resulted from strong credit performance in our portfolio and the reversal of unrealized depreciation due to spread tightening in the market during the second half of the calendar year 2023. Unrealized appreciation for the six months ended March 31, 2023 primarily resulted from loan repayments and improved performance of our portfolio companies. Unrealized depreciation for the six months ended March 31, 2024 primarily resulted from isolated deterioration in the credit performance of a small number of portfolio companies. Unrealized depreciation for the six months ended March 31, 2023 primarily resulted from decreases in the fair value across our portfolio company investments due to incremental spread widening in the market during the first quarter of the 2023 fiscal year and isolated deterioration in the credit performance of a small number of portfolio companies.

Liquidity and Capital Resources

For the six months ended March 31, 2024, we experienced a net increase in cash and cash equivalents, foreign currencies, restricted cash and cash equivalents and restricted foreign currencies of $8.8 million. During the period, we provided $30.3 million in operating activities, primarily as a result of the increase in net assets as a result from operations of $103.7 million and proceeds from principal payments and sales of portfolio investments of $123.0 million which was partially offset by fundings of portfolio investments of $168.4 million. During the same period, cash used by financing activities was $21.5 million, primarily driven by borrowings on debt of $225.4 million and proceeds from the issuance of common shares of $60.8 million, that were partially offset by repayments of debt of $208.1 million and distributions paid of $99.7 million.

For the six months ended March 31, 2023, we experienced a net increase in cash and cash equivalents, foreign currencies, restricted cash and cash equivalents and restricted foreign currencies of $42.5 million. During the period, we used $88.5 million in operating activities, primarily as a result of fundings of portfolio investments of $251.2 million, partially offset by proceeds from principal payments and sales of portfolio investments of $109.1 million. During the same period, cash provided by financing activities was $130.9 million, primarily driven by borrowings on debt of $512.4 million and proceeds from the issuance of common shares of $40.0 million, that were partially offset by repayments of debt of $399.2 million and distributions paid of $18.9 million.

As of March 31, 2024 and September 30, 2023, we had cash and cash equivalents of $7.4 million and $9.5 million, respectively. In addition, as of March 31, 2024 and September 30, 2023, we had foreign currencies of $2.7 million and $1.1 million, respectively, restricted cash and cash equivalents of $60.8 million and $55.7 million, respectively, and restricted foreign currencies of $4.7 million and $0.5 million, respectively. Cash and cash equivalents and foreign currencies are available to fund new investments, pay operating expenses and pay distributions. Restricted cash and cash equivalents and restricted foreign currencies can be used to pay principal and interest on borrowings and to fund new investments that meet the guidelines under our debt securitizations or credit facilities, as applicable.

129

Effective December 7, 2023, the Company entered into an agreement to cancel subscriptions totaling $0.7 million.

Adviser Revolver - On September 1, 2023, we entered into an amendment on the Adviser Revolver (as defined in Note 4 of our consolidated financial statements) to, among other things, increase the borrowing capacity from $40.0 million to $100.0 million, extend the maturity date to September 1, 2026, and to allow for borrowings in non-U.S. currencies. As of both March 31, 2024 and September 30, 2023, we were permitted to borrow up to $100.0 million at any one time outstanding under the Adviser Revolver. As of March 31, 2024 and September 30, 2023, we had no borrowings outstanding under the Adviser Revolver.

Debt Securitizations

2022-2 Debt Securitization - On December 14, 2022, we completed the 2022-2 Debt Securitization. The Class A 2022-2 Notes and Class A 2022-2 Loans (as defined in Note 8 of our consolidated financial statements) are included in the March 31, 2024 Consolidated Statement of Financial Condition as our debt and the Class B 2022-2 Notes and Subordinated 2022-2 Notes (as defined in Note 8 of our consolidated financial statements) were eliminated in consolidation. As of both March 31, 2024 and September 30, 2023, we had outstanding debt under the 2022-2 Debt Securitization of $225.0 million.

2022 Debt Securitization - On January 25, 2022, we completed the 2022 Debt Securitization.

As of

130

both March 31, 2024 and September 30, 2023, we had outstanding debt under the 2021 Debt Securitization of $298.0 million.

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

In accordance with the 1940 Act, with certain limited exceptions, we are currently allowed to borrow amounts such that our asset coverage, as defined in the 1940 Act, is at least 200% after such borrowing. We have not sought or obtained approval to reduce our asset coverage ratio as permitted by and subject to the requirements of Section 61(a)(2) of the 1940 Act and, as a result, remain subject to the 200% asset coverage requirement under Section 61(a)(1) of the 1940 Act. We currently intend to continue to target a GAAP debt-to-equity ratio of 0.85x. As of March 31, 2024, our asset coverage for borrowed amounts was 214.9%.

As of March 31, 2024, we had outstanding commitments to fund investments totaling $141.7 million, including $23.4 million of unfunded commitments on revolvers. As of September 30, 2023, we had outstanding commitments to fund investments totaling $176.0 million, including $22.5 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 as of March 31, 2024 and September 30, 2023, respectively. A summary of maturity requirements for our principal borrowings as of March 31, 2024 is included in Note 8 of our consolidated financial statements. We did not have any other material contractual payment obligations as of March 31, 2024. As of March 31, 2024, 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 and cash and restricted cash balances that we maintain, availability under our DB Credit Facility and Adviser Revolver, as well as ongoing principal repayments on debt investment assets.

In addition, we have entered and, in the future, may again enter into derivative instruments that contain elements of off-balance sheet market and credit risk. Refer to Note 6 of our consolidated financial statements for outstanding forward currency contracts as of March 31, 2024 and September 30, 2023. 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 may realize a loss. We minimize market risk through monitoring our investments and borrowings.

We called the remaining uncalled capital commitments from shareholders in December 2023. Although we expect to fund the growth of our investment portfolio through the net proceeds from our dividend reinvestment plan as well as 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, refinance, or enter into new 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.

Portfolio Composition, Investment Activity and Yield

As of March 31, 2024 and September 30, 2023, we had investments in 319 and 291 portfolio companies, respectively, with a total fair value of $2,698.8 million and $2,617.0 million, respectively.

(1)As of March 31, 2024, $368.1 million and $352.5 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 March 31, 2024, $7.1 million and $5.0 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, 2023, $297.0 million and $292.4 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, 2023, $4.6 million and $3.7 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 and interest or our management has reasonable doubt that principal or interest will be collected. See “Critical Accounting Policies — Revenue Recognition.”

As of March 31, 2024 and September 30, 2023, we had loans in four and two portfolio companies, respectively, on non-accrual status. As of March 31, 2024 and September 30, 2023, the fair value of our debt investments as a percentage of the outstanding principal value was 98.3% and 98.0%, respectively.

Weighted average rate of sales and payoffs of portfolio investments	11.2%	10.2%	10.5%	9.0%

As of March 31, 2024, 97.3% of our debt portfolio at both amortized cost and at fair value had interest rate floors that limit the minimum applicable interest rates on such loans. As of September 30, 2023, 97.9% of our debt portfolio at both amortized cost and at fair value had interest rate floors that limit the minimum applicable interest rates on such loans.

As of March 31, 2024 and September 30, 2023, the portfolio median1 earnings before interest, taxes, depreciation and amortization, or EBITDA, for our portfolio companies was $65.1 million and $61.4 million, respectively. The portfolio median EBITDA is based on the most recently reported trailing twelve-month EBITDA received from the portfolio company.

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.

1 The portfolio median EBITDA is based on our portfolio of debt investments and excludes (i) portfolio companies with negative or de minimis EBITDA, (ii) investments designated as recurring revenue loans and (iii) portfolio companies with any loans on non-accrual status.

133

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.

The following table shows the distribution of our investments on the 1 to 5 internal performance rating scale at fair value as of March 31, 2024 and September 30, 2023:

	As of March 31, 2024				As of September 30, 2023

Distributions

We intend to make periodic 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.

134

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.

135

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 BDC, Inc., or GBDC, a publicly-traded business development company (Nasdaq: GBDC), Golub Capital Direct Lending Corporation, or GDLC, Golub Capital BDC 4, Inc., or GBDC 4, Golub Capital Direct Lending Unlevered Corporation, or GDLCU, and Golub Capital Private Credit Fund, or GCRED, which are 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 GBDC, GDLC, GDLCU, GBDC 4 and GCRED. If GC Advisors and its affiliates determine that an investment is appropriate for us, GBDC, GDLC, GDLCU, GBDC 4, GCRED 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 Maryland.

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 by our board of directors under our valuation policy and process.

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, we 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 board of directors 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.

With respect to investments for which market quotations are not readily available, our board of directors undertakes a multi-step valuation process each quarter, as described below:

136

Our quarterly valuation process begins with each portfolio company investment being initially valued by the investment professionals of GC Advisors responsible for credit monitoring. Preliminary valuation conclusions are then documented and discussed with our senior management and GC Advisors. The audit committee of our board of directors reviews these preliminary valuations. At least once annually, the valuation for each portfolio investment, subject to a de minimis threshold, is reviewed by an independent valuation firm. The board of directors discusses valuations and determines the fair value of each investment in our portfolio in good faith.

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 management 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 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 may require significant management judgment or estimation.

In certain cases, the inputs used to measure fair value may 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. We assess 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 three and six months ended March 31, 2024 and 2023. 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.

137

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 our board of directors, based on input of management, the audit committee and independent valuation firms that have been engaged at the direction of our board of directors to assist in the valuation of each portfolio investment without a readily available market quotation at least once during a trailing twelve-month period under a valuation policy and a consistently applied valuation process. This valuation process is conducted at the end of each fiscal quarter, with approximately 25% (based on the number of portfolio companies) of our valuations of debt and equity investments without readily available market quotations subject to review by an independent valuation firm. All investments as of both March 31, 2024 and September 30, 2023 were valued using Level 3 inputs. As of both March 31, 2024 and September 30, 2023, all money market funds included in cash and cash equivalents and restricted cash and cash equivalents were valued using Level 1 inputs and all forward currency contracts were valued using Level 2 inputs.

When determining fair value of Level 3 debt and equity investments, we may 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 may affect the price at which similar investments may 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 may 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.

If debt investments are credit impaired, we will use the enterprise value analysis or a liquidation basis analysis to determine fair value. For debt investments that are not determined to be credit impaired, we use a market interest rate yield analysis to determine fair value.

In addition, for certain debt investments, we may base our 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 may be willing to pay. Ask prices represent the lowest price that we and others may be willing to accept. We generally use the midpoint of the bid/ask range as our 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 may differ significantly from the values that would have been used had a market existed for such investments and may differ materially from the values that may 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 may 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.

Pursuant to Rule 2a-5 under the 1940 Act, as recently amended, the board of directors of a registered investment company or BDC is permitted to delegate to a valuation designee, which could be its investment adviser, the responsibility to determine fair value of investments in good faith subject to the oversight of the board. Our board of directors has determined to continue its determination of fair value of our investments for which market quotations are not readily available in accordance with our valuation policies and procedures and has not designated GC Advisors or any other entity as a valuation designee.

138

In connection with each sale of shares of our common stock, we make a determination that we are not selling shares of our common stock at a price below the then-current net asset value per share of common stock at the time at which the sale is made or otherwise in violation of the 1940 Act. GC Advisors will consider the following factors, among others, in making such determination:

•The net asset value of our common stock disclosed in the most recent periodic report filed with the SEC; 

•Its assessment of whether any change in the net asset value per share of our common stock has occurred (including through the realization of gains on the sale of portfolio securities) during the period beginning on the date of the most recently disclosed net asset value per share of our common stock and ending two days prior to the date of the sale; and

•The magnitude of the difference between the sale price of the shares of common stock and management’s assessment of any change in the net asset value per share of our common stock during the period discussed above.

139

Valuation of Other Financial Assets and Liabilities

The fair value of our 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.

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. Premiums, discounts, and origination fees are amortized or accreted into interest income over the life of the respective debt investment. 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 may 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 and record these fees as fee income when earned. 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. 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 or 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 loans: 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 may 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 $5.1 million and $3.6 million as of March 31, 2024 and September 30, 2023, respectively.

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.

140

Depending on the level of taxable income earned in a tax year, we may choose to retain taxable income in excess of current year dividend distributions and would distribute such taxable income in the next tax year. We may 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 the three and six months ended March 31, 2024, we did not record any U.S. federal excise tax. For the three months ended March 31, 2023, we recorded a reversal of the accrual for U.S. federal excise tax expense of less than $0.1 million. For the six months ended March 31, 2023, we recorded $0.6 million for U.S. federal excise tax.

We have consolidated subsidiaries that are subject to U.S. federal and state corporate-level income taxes. For the three and six months ended March 31, 2024, $8,000 was recorded for U.S. income taxes. For the three and six months ended March 31, 2023, the we did not record any U.S. income taxes. Because federal income tax regulations differ from GAAP, distributions in accordance with tax regulations may differ from net investment income and realized gains recognized for financial reporting purposes. Differences may 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 may 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.

141

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are subject to financial market risks, including changes in interest rates. Many of the loans in our portfolio have floating interest rates, and we expect that our loans in the future may 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 both March 31, 2024 and September 30, 2023, the weighted average floor on loans subject to floating interest rates was 0.79%. The DB Credit Facility has a floating interest rate provision equal to three-month term SOFR + 2.55%, the Adviser Revolver has a floating interest rate provision equal to the short-term Applicable Federal Rate, the Class A Notes and Class A Loans issued in connection with the 2022-2 Debt Securitization have floating rate provisions based on three-month term SOFR, the Class A Senior Secured Notes issued in connection with the 2022 Debt Securitization have floating rate interest provisions based on three-month term SOFR and the Class A, B, and C-1 2021 Notes issued in connection with the 2021 Debt Securitization have floating rate interest provisions based on three-month SOFR plus a spread adjustment. We expect that other credit facilities 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, 2024 were 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 interest income(1)		Increase (decrease) in interest expense		Net increase (decrease) in  investment income
	(In thousands)
Down 200 basis points	$	(50,977)	$	(25,006)	$	(25,971)
Down 150 basis points	(38,233)		(18,754)		(19,479)
Down 100 basis points	(25,489)		(12,503)		(12,986)
Down 50 basis points	(12,744)		(6,251)		(6,493)
Up 50 basis points	12,744		6,251		6,493
Up 100 basis points	25,489		12,503		12,986
Up 150 basis points	38,233		18,754		19,479
Up 200 basis points	50,977		25,006		25,971

(1) Assumes applicable three-month base rate as of March 31, 2024, with the exception of SONIA and Prime that utilize the March 31, 2024 rate.

Although we believe that this analysis is indicative of our sensitivity to interest rate changes as of March 31, 2024, 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 DB Credit Facility, the Adviser Revolver, the Debt Securitizations 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.

We could in the future 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 may insulate us against adverse changes in interest rates, they may 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.

142

Item 4. Controls and Procedures

As of March 31, 2024 (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.
