Note 1. Organization

Golub Capital Private Income Fund S (“GPIF S” or the “Company”), is a Delaware statutory trust formed on July 22, 2025. The Company is an externally managed, non-diversified, closed-end management investment company that commenced operations on December 31, 2025, the effective date of the Company’s election to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). In addition, for U.S. federal income tax purposes, beginning with its tax year ending September 30, 2026, the Company intends to elect 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 fiscal year end is September 30.

The Company’s investment objective is to generate current income and capital appreciation by investing primarily in privately originated and privately negotiated investments, predominantly through direct lending to U.S. private companies in the middle-market in the form of 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. The Company could selectively invest in second lien and subordinated loans (including loans that rank senior only to a borrower’s equity securities and ranks junior to all of such borrower’s other indebtedness in priority of payment) of private companies. The Company also expects to invest in liquid credit instruments, including secured floating rate syndicated loans (e.g., broadly syndicated loans), securitized products and corporate bonds, and the Company’s portfolio may, but will not necessarily, initially be comprised of a greater percentage of such instruments than it will as the Company’s investment program matures, though the exact allocation could vary from time to time depending on market conditions and available investment opportunities. The Company’s portfolio could also include other credit-related investments, including, without limitation, structured and synthetic debt investments and debt investments accompanied by equity securities, preferred equity and, to a limited extent, common equity investments not associated with a debt investment. The Company has entered into an investment advisory agreement dated December 5, 2025 (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 dated December 5, 2025 (the “Administration Agreement”) the Company is provided with certain services by an administrator, which is currently Golub Capital LLC (the “Administrator”).

The Company offers its common shares of beneficial interest, par value $0.01 per share (“Common Shares”), in one or more private placement transactions exempt from registration under the U.S. Securities Act of 1933, as amended, pursuant to Section 4(a)(2), Regulation D, and/or Regulation S (the “Offering”), including a private placement of Common Shares to certain purchasers that closed prior to the commencement of the Offering (the “Initial Offering”).

Prior to the Initial Offering, GCP-PIF Feeder S (“GPIF S Feeder”), a Delaware statutory trust and indirectly wholly-owned subsidiary of GCP HS Fund, purchased 820,400 Common Shares at a price of $25.00 per share (the “Initial Capitalization”). The investment manager for GPIF S Feeder and GCP HS Fund is an affiliate of the Investment Adviser. Prior to the Initial Offering closing, the Board authorized the redemption of all of the Initial Capitalization Common Shares outstanding at a price of $25.00 per share effective December 31, 2025.

On December 29, 2025, prior to the Company’s election to be regulated as a BDC, the Company entered into a share purchase and sale agreement to acquire its initial portfolio of investments by purchasing 100% of the beneficial interests of each of GPIF S Holdings, GPIF S Funding and PIF Holding Blocker S (the “Initial Assets”) from GCP OS Cayman Trust, a Cayman Islands trust (“OS Cayman Trust”) pursuant to a share purchase and sale agreement by and among the Company, OS Cayman Trust and the Investment Adviser (the “GPIF S Purchase Agreement”). On December 31, 2025, the Company commenced operations and invested proceeds from the Initial Closing to acquire the Initial Assets.

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 the 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.

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. The board of trustees of the Company (the “Board”) designated the Investment Adviser as the Company’s valuation designee (“Valuation Designee”) in accordance with Rule 2a-5 under the 1940 Act. The Valuation Designee is responsible for determining the fair value of the Company’s portfolio investments, subject to oversight of the Board. In accordance with ASC Topic 820, the Valuation Designee has categorized the Company’s financial instruments carried at fair value, based on the priority of the valuation technique, into a three-level fair value hierarchy. Fair value is a market-based measure considered from the perspective of the market participant who holds the financial instrument rather than an entity-specific measure. Therefore, when market assumptions are not readily available, the Investment Adviser’s own assumptions are set to reflect those that management believes market participants would use in pricing the financial instrument at the measurement date.

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

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

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

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, GPIF S Holdings (“Holdings”), GPIF S Funding (“Funding”) and PIF Holding Blocker S (“PIF Holding”) in its consolidated financial statements.

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

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

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

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

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

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

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

Refer to Note 5 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.

Original issue discount, market discount or premium and certain loan origination or amendment fees that are deemed to be an adjustment to yield (“Loan Origination Fees”) are capitalized and the Company accretes or amortizes such amounts over the life of the loan as interest income (“Discount Amortization”). For the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, the Company received Loan Origination Fees that were capitalized of $25 and $380, respectively. For the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, interest income included $35 and $61, respectively, of Discount Amortization.

For investments with contractual payment-in-kind (“PIK”) interest, which represents contractual interest accrued and added to the principal balance that generally becomes due at maturity, the Company will not accrue PIK interest if the portfolio company valuation indicates that the PIK interest is not collectible. For the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, investment income included $213 and $436, respectively, of PIK interest and the Company capitalized PIK interest of $208 and $419, respectively, into the principal balance of certain debt investments.

In addition, the Company generates revenue in the form of amendment, structuring or due diligence fees, fees for providing managerial assistance, consulting fees, administrative agent fees, and prepayment premiums on loans. The Company records these fees that are not deemed to be an adjustment to yield as fee income when earned. For both the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, fee income included no non-recurring prepayment premiums. All other income is recorded into income when earned.

For the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, the Company received interest and fee income in cash, which excludes capitalized Loan Origination Fees, in the amount of $5,365 and $9,425, 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 months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, the Company recognized PIK and non-cash dividend income of $22 and $56, respectively, which were capitalized into the cost basis of certain preferred equity investments. For both the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, the Company did not receive any cash payments of accrued and capitalized preferred dividends.

Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly-traded portfolio companies. Each distribution received from limited liability company (“LLC”) and limited partnership (“LP”) investments is evaluated to determine if the distribution should be recorded as dividend income or a return of capital. Generally, the Company will not record distributions from equity investments in LLCs and LPs as dividend income unless there are sufficient accumulated tax-basis earnings and profits in the LLC or LP prior to the distribution. Distributions that are classified as a return of capital are recorded as a reduction in the cost basis of the investment. For both the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, the Company did not recognize any dividend income received in cash and did not receive any return of capital distributions in cash.

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

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

Management reviews all preferred equity securities accruing contractual PIK dividend income to determine if there is reasonable doubt that amortized cost or capitalized PIK and non-cash dividend income will be collected for possible placement on non-accrual status. When a preferred equity security is placed on non-accrual status, the contractual PIK dividend provision is no longer accrued to dividend income as of the date the preferred equity security is placed on non-accrual status. As of June 30, 2026, there was one preferred equity security on non-accrual status with a fair value of $386.

Income taxes: Beginning with its tax year ending September 30, 2026, the Company intends to elect to be treated, and intends to qualify annually thereafter, as a RIC under Subchapter M of the Code and intends to operate in a manner so as to qualify for the tax treatment applicable to RICs. In order to qualify and be subject to taxation as a RIC, among other things, the Company will be required to meet certain source of income and asset diversification requirements and timely distribute dividends for U.S. federal income tax purposes to its shareholders 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. Beginning with its tax year ending September 30, 2026, the Company intends to make the requisite distributions to its shareholders, which will generally relieve the Company from U.S. federal income taxes with respect to all income distributed to its shareholders.

Depending on the level of taxable income earned in a tax year, the Company can determine to retain taxable income in excess of current year dividend distributions and distribute such taxable income in the next tax year. The Company could then be required to incur a 4% excise tax on such income. To the extent that the Company determines that its estimated current year annual taxable income, determined on a calendar year basis, could exceed estimated current calendar year dividend distributions, the Company accrues excise tax, if any, on estimated excess taxable income as taxable income is earned. For both the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, the Company did not record any U.S. federal excise tax.

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 June 30, 2026. The Company’s tax return for the 2025 tax year remains 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 months ended June 30, 2026, the Company did not incur U.S income tax. For the period from December 31, 2025 (commencement of operations) to June 30, 2026, the Company recorded $9 of U.S. income tax.

Dividends and distributions: Dividends and distributions to common shareholders 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 distribution reinvestment plan (“DRIP”) that provides for reinvestment of any distributions the Company declares in cash on behalf of its shareholders, unless a shareholder elects to receive cash. As a result, if the Board authorizes and the Company declares a cash distribution, then shareholders who have not “opted out” of the DRIP will have their cash distribution automatically reinvested in additional Common Shares, rather than receiving the cash distribution. Common Shares issued under the DRIP will be issued at a price per share equal to the most recent net asset value (“NAV”) per share for such shares at the time the distribution is payable.

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 June 30, 2026, the Company had deferred debt issuance costs of $800. These amounts are amortized and included in “Interest and other debt financing expenses” in the Consolidated Statements of Operations over the estimated average life of the borrowings. Amortization expense for deferred debt issuance costs for the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026 was $34 and $62, respectively.

Deferred offering costs: Costs associated with the offering of Common Shares will be capitalized as deferred offering expenses and amortized on a straight line basis. Deferred offering costs consist of fees paid in relation to legal, accounting, regulatory and printing work completed in preparation of equity offerings. For the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, the Company amortized $231 and $423, respectively, of deferred offering costs, which are included in “Professional fees” on the Consolidated Statements of Operations.

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

The Company operates through a single operating and reporting segment with an investment objective to generate both current income and, to a lesser extent, capital appreciation through debt and equity investments. The chief operating decision maker (the “CODM”) is comprised of the senior executive committee that, as of June 30, 2026, includes the Company’s chief executive officer, chief financial officer and chief operating officer and assesses the performance and makes operating decisions of the Company on a consolidated basis primarily based on the Company’s net increase (decrease) in net assets resulting from operations (“net income”). In addition to numerous other factors and metrics, the CODM utilizes net income as a key metric in evaluating the Company’s distribution policy. Performance metrics are provided to the CODM on a quarterly basis and are utilized to evaluate performance generated from segment net assets. As the Company’s operations comprise of a single reporting segment, the segment assets are reflected on the accompanying Consolidated Statement of Financial Condition as “total assets” and the significant segment expenses are listed on the accompanying Consolidated Statements of Operations.

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

Investment Advisory Agreement: Under the Investment Advisory Agreement, the Investment Adviser manages the day-to-day operations of, and provides investment advisory services to the Company. The Investment Adviser is a registered investment adviser with the SEC. The Investment Adviser receives fees for providing services under the Investment Advisory Agreement consisting of two components: a base management fee and an incentive fee.

Base Management Fee

The base management fee is calculated at an annual rate of 1.25% of the value of the Company’s net assets as of the beginning of the first calendar day of the applicable quarter adjusted for share issuances and repurchases and is payable quarterly in arrears. For purposes of the Investment Advisory Agreement, net assets means the Company’s assets less liabilities determined in accordance with GAAP. To the extent the Investment Adviser or an affiliate of the Investment Adviser provides investment advisory, collateral management or other similar services to a subsidiary of the Company, the Company’s management fee will be reduced by an amount equal to the product of (a) the total fees paid to the Investment Adviser by such subsidiary for such services and (b) the percentage of such subsidiary’s total equity that is owned, directly or indirectly, by the Company.

The base management fee incurred for the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026 was $357 and $703, respectively.

Incentive Fees

The incentive fee consists of two components that are independent of each other, with the result that one component could be payable even if the other is not. A portion of the incentive fee is based on a percentage of the Company’s income and a portion is based on a percentage of the Company’s capital gains, each as described below.

(i) Income based incentive fee (the “Income Incentive Fee”)

The Income Incentive Fee is based on Pre-Incentive Fee Net Investment Income Returns. “Pre-Incentive Fee Net Investment Income Returns” means, as the context requires, either the dollar value of, or percentage rate of return on the value of net assets at the end of the immediate preceding quarter, adjusted for share issuances and repurchases, from, interest income, dividend income and any other income (including any other fees (other than fees for providing managerial assistance), such as commitment, origination, structuring, diligence and consulting fees or other fees that are received from portfolio companies) accrued during the calendar quarter, minus operating expenses accrued for the quarter (including the management fee, expenses payable under the Administration Agreement and any interest expense or fees on any credit facilities or outstanding debt and dividends paid on any issued and outstanding preferred shares, but excluding the incentive fee and any distribution or shareholder servicing fees).

Pre-Incentive Fee Net Investment Income Returns include, in the case of investments with a deferred interest feature (such as original issue discount, debt instruments with PIK interest and zero coupon securities), accrued income that has not yet been received in cash. Pre-Incentive Fee Net Investment Income Returns do not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. The impact of expense support payments and recoupments are also excluded from Pre-Incentive Fee Net Investment Income Returns. Pre-Incentive Fee Net Investment Income Returns, expressed as a rate of return on the value of the Company’s net assets at the end of the immediate preceding quarter, is compared to a “hurdle rate” of return of 1.25% per quarter (5.0% annualized).

The Company pays the Investment Adviser quarterly in arrears an Income Incentive Fee with respect to the Company’s Pre-Incentive Fee Net Investment Income Returns in each calendar quarter as follows:

•No incentive fee based on Pre-Incentive Fee Net Investment Income Returns in any calendar quarter in which Pre-Incentive Fee Net Investment Income Returns do not exceed the hurdle rate of 1.25% per quarter (5.0% annualized);

•100% of the dollar amount of Pre-Incentive Fee Net Investment Income Returns with respect to that portion of such Pre-Incentive Fee Net Investment Income Returns, if any, that exceeds the hurdle rate but is less than a rate of return of 1.43% (5.72% annualized). This portion of Pre-Incentive Fee Net Investment Income Returns that exceeds the hurdle rate but is less than 1.43% is referred to as the “catch-up” provision; and

•12.5% of the dollar amount of Pre-Incentive Fee Net Investment Income Returns, if any, that exceed a rate of return of 1.43% (5.72% annualized). This reflects that once the hurdle rate is reached and the catch-up is achieved, 12.5% of all Pre-Incentive Fee Net Investment Income Returns thereafter are allocated to the Investment Adviser.

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 months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, the Income Incentive Fee incurred was $302 and $532, respectively.

(ii) Capital gains based incentive fee (the “Capital Gain Incentive Fee”)

The second component of the incentive fee, the Capital Gain Incentive Fee, is payable at the end of each calendar year in arrears. The amount payable equals

•12.5% of cumulative realized capital gains from inception through the end of each calendar year, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid Capital Gain Incentive Fee.

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. Each year, the fee paid for the Capital Gain Incentive Fee is net of the aggregate amount of any previously paid Capital Gains Incentive Fee for all prior periods.

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

In accordance with GAAP, the Company also is required to include the aggregate unrealized capital appreciation on investments in the calculation and accrue a capital gain incentive fee on a quarterly basis, as if such unrealized capital appreciation were realized, even though such unrealized capital appreciation is not permitted to be considered in calculating the fee actually payable under the Investment Advisory Agreement, as applicable. There can be no assurance that any such unrealized capital appreciation will be realized in the future. For the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, the Company did not accrue a capital gain incentive fee under GAAP. As of June 30, 2026, there was no cumulative accrual for the capital gain incentive fee under GAAP.

Administration Agreement: Under the Administration Agreement, the Administrator furnishes the Company with office facilities and equipment, provides, or oversees the performance of, administrative and compliance services, including, but not limited to, maintaining financial records, overseeing the calculation of NAV, preparing reports to shareholders and reports filed with the SEC, overseeing the preparation and filing of tax returns and the printing and dissemination of reports to shareholders, managing the payment of expenses and the performance of administrative and professional services rendered by others. The Company reimburses the Administrator for costs and expenses including, but not limited to, those related to the allocable portion of the Administrator’s overhead and other expenses incurred by it in performing its obligations under the Administration Agreement, including 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 those 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.

Included in “Accounts payable and other liabilities” is $77, as of June 30, 2026 for accrued allocated shared services under the Administration Agreement.

Each of the Investment Advisory Agreement and the Administration Agreement were approved by the Board, and both became effective on December 5, 2025 and will continue in effect for an initial term of two years. The Company may terminate the Investment Advisory Agreement or the Administration Agreement, without payment of any penalty, upon 60 days’ written notice.

Managing Dealer Agreement: The Company has entered into a managing dealer agreement (as amended, the “Managing Dealer Agreement”) with Arete Wealth Management, LLC (the “Managing Dealer”). Under the terms of the Managing Dealer Agreement, the Managing Dealer will manage relationships with third-party brokers engaged by the Managing Dealer to participate in the distribution of the Company’s Common Shares (referred to as “participating brokers”), and financial advisors. The Managing Dealer will be entitled to receive shareholder servicing and/or distribution fees monthly in arrears at an annual rate of 0.85% of the aggregate NAV attributable to the Company’s common shares. The shareholder servicing and/or distribution fees will be payable to the Managing Dealer, but the Managing Dealer anticipates that all or a portion of the shareholder servicing fees and/or distribution fees will be retained by, or reallowed (paid) to, participating brokers. In addition, pursuant to the Managing Dealer Agreement, the Company will pay the Managing Dealer certain fees for its services as Managing Dealer, including a 1.75 basis point managing dealer fee that is payable quarterly in arrears on any new capital raised in the Offering. Such fees are borne indirectly by all shareholders of the Company. For the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, the Company incurred $6 and $14, respectively, of fees to the Managing Dealer, which are included in “Professional fees” on the Consolidated Statements of Operations.

The Managing Dealer is a broker-dealer registered with the SEC and a member of the Financial Industry Regulatory Authority (“FINRA”).

On May 1, 2026, the Board approved an amended and restated Managing Dealer Agreement, to be effective as of June 1, 2026. The Managing Dealer Agreement may be terminated at any time, without the payment of any penalty, by vote of a majority of the Company’s trustees who are not “interested persons”, as defined in the 1940 Act, of the Company and who have no direct or indirect financial interest in the operation of the Company’s distribution and servicing plan or the Managing Dealer Agreement or by vote of a majority of the outstanding voting securities of the Company, on not more than 60 days’ written notice to the Managing Dealer or the Investment Adviser. The Managing Dealer Agreement will automatically terminate in the event of its assignment, as defined in the 1940 Act.

Expense Support and Conditional Reimbursement Agreement: The Company has entered into an expense support and conditional reimbursement agreement (the “Expense Support Agreement”) with the Investment Adviser. The Investment Adviser may elect to pay certain expenses on the Company’s behalf (each, an “Expense Support Payment”), provided that no portion of the payment will be used to pay any of the Company’s interest expense or distribution and/or shareholder servicing fees. Any Expense Support Payment that the Investment Adviser has committed to pay must be paid by the Investment Adviser to the Company in any combination of cash or other immediately available funds no later than forty-five days after such commitment was made in writing, and/or offset against amounts due from the Company to the Investment Adviser or its affiliates.

Following any calendar month in which Available Operating Funds (as defined below) exceed the cumulative distributions accrued to the Company’s shareholders based on distributions declared with respect to record dates occurring in such calendar month (the amount of such excess being hereinafter referred to as “Excess Operating Funds”), the Company shall pay such Excess Operating Funds, or a portion thereof, to the Investment Adviser until such time as all Expense Support Payments made by the Investment Adviser to the Company within three years prior to the last business day of such calendar month have been reimbursed. Any payments required to be made by the Company shall be referred to herein as a “Reimbursement Payment”. “Available Operating Funds” means the sum of the Company’s (i) net investment income calculated in accordance with GAAP, (ii) net capital gains (including the excess of net long-term capital gains over net short-term capital losses) and (iii) dividends and other distributions paid to the Company on account of investments in portfolio companies (to the extent such amounts listed in clause (iii) are not included under clauses (i) and (ii) above).

The Company’s obligation to make a Reimbursement Payment shall automatically become a liability of the Company on the last business day of the applicable calendar month, except to the extent the Investment Adviser has waived its right to receive such payment for the applicable month.

As of June 30, 2026, $2,032 of unreimbursed Expense Support Payments receivable from the Investment Adviser were included in “Other assets” on the Consolidated Statement of Financial Condition.

Exclusion of the Investment Adviser from Commodity Pool Operator Definition

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

Note 6. Fair Value Measurements

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

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

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

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

In certain cases, the inputs used to measure fair value fall into different levels of the fair value hierarchy. In such cases, an asset’s or a liability’s categorization within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The Valuation Designee assesses the levels of assets and liabilities at each measurement date, and transfers between levels are recognized on the actual date of the event or change in circumstances that caused the transfers. There were no transfers among Level 1, 2 and 3 of the fair value hierarchy for assets and liabilities during the period from December 31, 2025 (commencement of operations) to June 30, 2026. The following section describes the valuation techniques used to measure different assets and liabilities at fair value and includes the level within the fair value hierarchy in which the assets and liabilities are categorized.

being initially valued, based on the fair value methodology in accordance with ASC Topic 820 described below, either by (i) professionals of the Valuation Designee responsible for the valuation function or (ii) investment valuation firms that have been engaged to support the valuation of portfolio investments. The valuation for each portfolio investment, or approximately 100% (based on the fair value of portfolio company investments) of the Company’s debt and equity investments without readily available market quotations (subject to a de minimis threshold), was either (i) performed by or (ii) reviewed by an independent valuation firm. As of June 30, 2026, $36,372 and $212,074 of investments were valued using Level 2 inputs and Level 3 inputs, respectively. As of June 30, 2026, all forward currency contracts were valued using Level 2 inputs and all money market funds included in cash equivalents and restricted cash equivalents were valued using Level 1 inputs.

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

In addition, for certain debt investments, the Valuation Designee bases its valuation on indicative bid and ask prices provided by an independent third-party pricing service or directly from independent brokers. Bid prices reflect the highest price that the Company and others could be willing to pay. Ask prices represent the lowest price that the Company and others could be willing to accept. The Valuation Designee generally uses the midpoint of the independent third-party market “bid” and “ask” quotes to determine the value of our portfolio investments but may use another value if the Valuation Designee determines it better represents the investment’s fair value. While market price quotes from third-party pricing sources may be available, the Valuation Designee has the discretion to seek and utilize independent quotes from independent broker dealers to determine the fair value of the applicable portfolio investment. The Valuation Designee may obtain and consider both “bid” and “ask” quotes from either independent third-party vendors or directly from independent brokers.

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

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

(2)The Company valued $184,678 and $12,803 of one stop loans using EBITDA and revenue multiples, respectively.

(3)$104 of loans at fair value were valued using the market comparable companies approach only.

(4)The Company valued $2,672 and $1,350 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 Valuation Designee.

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

Other Financial Assets and Liabilities

ASC Topic 820 requires disclosure of the fair value of financial instruments for which it is practical to estimate such value. As a result, with the exception of the line item titled “Debt” which is reported at cost or the carrying value (as defined in the table below), all assets and liabilities approximate fair value on the Consolidated Statement of Financial Condition due to their short maturity. The fair value of the Company’s revolving credit facility approximates the carrying value due to their variable interest rates based on selected short-term rates. The fair value of the Company’s RF Notes (as defined in Note 7) is approximated by the carrying value.

The following is the carrying value and fair value of the Company’s debt as of June 30, 2026:


	As of June 30, 2026
	Carrying Value		Fair Value
Debt(1)	$	142,797	$	142,797

Note 7. Borrowings

In accordance with the 1940 Act, with certain limited exceptions, the Company is currently allowed to borrow amounts such that its asset coverage, as defined in the 1940 Act, is at least 150% after such borrowing. On December 31, 2025, the Company’s sole shareholder approved the application of the reduced asset coverage requirements of Section 61(a)(2) of the 1940 Act and declined the Company’s offer to repurchase all of its outstanding Common Shares. As a result of such approval, effective as of the date of the Company’s election to be regulated as a BDC on December 31, 2025, the Company’s asset coverage requirement was reduced from 200% to 150%, or a ratio of total debt-to-equity of 2:1 as compared to a maximum of 1:1 under the 200% asset coverage requirement under the 1940 Act. As of June 30, 2026, the Company’s asset coverage for borrowed amounts was 181.6%.

BANA Credit Facility: Effective December 31, 2025, the Company assumed, in connection with the GPIF S Purchase Agreement, Funding’s revolving credit and security agreement (as amended and/or restated from time to time, the “BANA Credit Facility”) with the Company, as servicer, Bank of America, N.A., as administrative agent and sole lender, and Computershare Trust Company, N.A., as collateral custodian. Under the BANA Credit Facility, the lenders have agreed to extend credit to Funding in an aggregate principal amount of up to $425,000 as of December 31, 2025. Funding may request drawdowns under the BANA Credit Facility through December 11, 2028 and the BANA Credit Facility will mature on December 11, 2031, the sixth anniversary of the closing date of the BANA Credit Facility.

Borrowings under the BANA Credit Facility accrue interest at a rate per annum equal to the floating rate applicable to the currency of such borrowing (which, for U.S. dollar-denominated borrowings, is three-month term SOFR), plus an applicable margin, which is based on the composition of the portfolio and ranges from a floor of 1.70% per annum to 1.85% per annum. Additionally, for periods beginning after June 30, 2026, Funding pays a commitment fee on the unused portion of commitments of either 0.50% or 1.75% (or both) per annum, based on the amount of the unfunded commitments. A prepayment fee may be payable in the event of any permanent reduction in commitments of the BANA Credit Facility.

The BANA Credit Facility is secured by all of the assets held by Funding. Funding has made customary representations and warranties and is required to comply with various covenants, reporting requirements and other customary requirements for similar credit facilities.

The borrowings of the Company, including under the BANA Credit Facility, are subject to the leverage restrictions contained in the 1940 Act.

As of June 30, 2026, the Company had $142,401 of outstanding debt under the BANA Credit Facility.

Note 8. Commitments and Contingencies

Commitments: As of June 30, 2026, the Company had outstanding commitments to fund investments totaling $32,429, including $17,127 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 Statement of Financial Condition. The Company has entered and, in the future, could again enter into derivative instruments that contain elements of off-balance sheet market and credit risk. Refer to Note 5 for outstanding forward currency contracts as of June 30, 2026. Derivative instruments can be affected by market conditions, such as 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 any 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 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.

Share Repurchase Program

Beginning no later than the second full calendar quarter from the Initial Closing, and at the discretion of the Board, the Company will commence a share repurchase program in which the Company intends to repurchase, in each quarter, up to 5% of the NAV of the Company’s Common Shares outstanding as of the close of the calendar quarter prior to the applicable valuation date (the “Determination Date”). The Board may amend, suspend or terminate the share repurchase program upon 30 days’ notice, if it deems such action to be in the best interest of shareholders. As a result, share repurchases may not be available each quarter. The Company intends to conduct such repurchase offers in accordance with the requirements of Rule 13e-4 promulgated under the Securities Exchange Act of 1934, as amended, and the 1940 Act. All shares purchased pursuant to the terms of each tender offer will be retired and thereafter will be authorized and unissued shares.

Under the share repurchase program, to the extent the Company offers to repurchase shares in any particular quarter, it is expected to repurchase shares pursuant to tender offers on or around the last business day of the first month of such quarter using a purchase price equal to the NAV per share as of the last calendar day of the prior quarter, except that shares that have not been outstanding for at least one year will be repurchased at 98% of such NAV (an “Early Repurchase Deduction”). The Early Repurchase Deduction will be retained by the Company for the benefit of remaining shareholders.

We have not independently verified such statistics or data.

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 intend to elect 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 after our election to be treated as a RIC, limitations imposed by the Code. We were formed in July 2025 as a Delaware statutory trust. We commenced investment operations on December 31, 2025.

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. In addition, we expect to invest in liquid credit instruments, including secured floating rate syndicated loans (e.g., broadly syndicated loans), securitized products and corporate bonds though the exact allocation could vary from time to time depending on market conditions and available investment opportunities. Our portfolio may also include other credit-related investments, including, without limitation, structured and synthetic debt investments and debt investments accompanied by equity securities, preferred equity and, to a limited extent, common equity investments not associated with a debt investment. We intend to achieve our investment objective by (1) accessing the established loan origination channels developed by Golub Capital, a leading lender to U.S. middle-market companies with over $90.0 billion in capital under management1 as of April 1, 2026, (2) selecting investments within our core middle-market company focus, (3) partnering with experienced private equity firms, or sponsors, in many cases with whom Golub Capital has invested alongside in the past, (4) implementing the disciplined underwriting standards of Golub Capital and (5) drawing upon the aggregate experience and resources of Golub Capital.

Our investment activities are managed by GC Advisors and supervised by the Board 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 the value of our net assets as well as an incentive fee based on our investment performance. Under an administration agreement, or the Administration Agreement, we are provided with certain administrative services by an administrator, or the Administrator. Under the Administration Agreement, we have agreed to reimburse the Administrator for our costs and expenses, including, but not limited to, those related to the allocable portion (subject to the review and approval of our independent trustees) of overhead and other expenses incurred by the Administrator in performing its obligations under the Administration Agreement.

1 “Capital under management” is a gross measure of invested capital including leverage as of April 1, 2026.

We seek to invest at least 80% of our total assets (net assets plus borrowings for investment purposes) directly or indirectly in private credit investments (loans, bonds and other credit and related instruments that are issued in private offerings or issued by private companies). If we change our 80% test, we will provide shareholders with at least 60 days’ notice of such change.

We expect to make investments that typically will have position sizes under 1% of our portfolio, on average. We expect to selectively invest more than 1% of our portfolio 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, particularly during the period prior to raising sufficient capital, which may result in larger individual investments when and if our capital base increases. We may invest in companies of any size or capitalization.

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

As of June 30, 2026, our portfolio at fair value was comprised of the following:


	As of June 30, 2026
Investment Type	Investments at Fair Value (in thousands)		Percentage of Total Investments
Senior secured	$	45,902	18.5	%
One stop	197,998		79.7
Second lien	524		0.2

Equity	4,022		1.6
Total	$	248,446	100.0	%

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 June 30, 2026, one stop loans included $12.8 million of recurring revenue loans at fair value.

Senior secured loans include broadly syndicated loans (“BSLs”) where we do not act as lead arranger, joint lead arranger or co-manager. As of June 30, 2026, senior secured loans included $40.9 million of BSLs at fair value.

As of June 30, 2026, we had debt and equity investments in 158 portfolio companies.

The following table shows the weighted average annualized income yield and weighted average annualized investment income yield of both our earning and total portfolio company investments for the three months ended June 30, 2026:



	Three months ended June 30, 2026		Period from December 31, 2025 (commencement of operations) to June 30, 2026

Weighted average income yield(1)*	8.9	%	8.8	%
Weighted average investment income yield(2)*	8.9	%	8.9	%
Weighted average income yield of total investments(3)*	8.8	%	8.7	%

(4)Represents income from interest, fees, interest earned on cash, accrued PIK and non-cash dividend income and amortization of capitalized fees and discounts, divided by the daily average total fair value of portfolio investments, and does not represent a return to any investor in us.

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 our 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:

•organizational expenses;

•calculating our NAV (including the cost and expenses of any independent valuation firm);

•fees and expenses incurred by GC Advisors and 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;

•interest payable on debt, if any, incurred by us to finance its investments and expenses related to unsuccessful portfolio acquisition efforts;

•offerings of our Common Shares or other securities, including any public or private offering of our Common Shares;

•investment advisory fees, including management fees and incentive fees;

•administration fees and expenses 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, fees and expenses associated with performing compliance functions 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;

•fees payable to transaction/brokerage platforms;

•subscription processing fees and expenses;

•reasonable bona fide due diligence expenses of participating broker-dealers supported by detailed and itemized invoices;

•fees incurred by us for transfer agent, dividend agent and custodial fees and expenses;

•fees and expenses payable under any managing dealer and selected dealer agreements, if any;

•all costs of registration and listing of our securities on any securities exchange, if applicable;

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

•U.S. federal, state and local taxes;

•independent trustees’ fees and expenses;

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

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

•costs associated with individual or group shareholders;

•costs of registration rights granted to certain investors;

•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, trustees 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;

•costs and expenses, including travel, meals, accommodations, entertainment and other similar expenses, incurred by GC Advisors or its affiliates for meetings with existing investors and any intermediaries, registered investment advisors, financial and other advisors representing such existing investors;

•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.

We have entered into an Expense Support and Conditional Reimbursement Agreement (the “Expense Support Agreement”) with GC Advisors. Under the Expense Support Agreement, GC Advisors may elect to pay certain expenses on our behalf (each, an “Expense Support Payment”), provided that no portion of the payment will be used to pay any of our interest expense or distribution and/or shareholder servicing fees. Refer to Note 3 of our consolidated financial statements for further details on the Expense Support Agreement.

Recent Developments

The Company received $1.7 million of net proceeds from the issuance of Common Shares for subscriptions effective July 1, 2026. The Company received an approximate amount of $0.1 million of net proceeds from the issuance of Common Shares for subscriptions effective August 1, 2026.

As we commenced operations on December 31, 2025, no income was earned prior to December 31, 2025.

Investment Income

The annualized income yield by debt security type for the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026(1) are as follows:


	Three months ended June 30, 2026		Period from December 31, 2025 (commencement of operations) to June 30, 2026
Senior secured	7.4	%	7.6	%
One stop	9.0	%	8.9	%
Second lien	13.3	%	13.2	%

Our loan portfolio is partially insulated from a drop in floating interest rates as 99.0% of our loan portfolio at fair value as of June 30, 2026 is subject to an interest rate floor. As of June 30, 2026, the weighted average base floor of our loans was 0.70%.

As of June 30, 2026, we have second lien investments in one portfolio company as shown in the Consolidated Schedule of Investments. Due to the limited number of second lien debt investments, income yields on second lien 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.

(1) No comparative variance analysis was performed for the period from December 31, 2025 (commencement of operations) to June 30, 2026 due to the Company’s commencement of operations on December 31, 2025.

Interest Expense

For more information about our outstanding borrowings for the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, including the terms thereof, see Note 7 in the notes to our consolidated financial statements and the “Liquidity and Capital Resources” section below.

For both the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, the effective average interest rate, which includes amortization of debt financing costs and non-usage facility fees on our total debt was 5.5%.

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.

For the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026, we were fully through the catch-up provision of the Income Incentive Fee calculation and the Income Incentive Fee, as a percentage of Pre-Incentive Fee Net Investment Income, was 12.5%.

As of June 30, 2026, 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 Capital Gain Incentive Fee actually payable under the Investment Advisory Agreement. As of June 30, 2026, there was no capital gain incentive fee accrual 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 June 30, 2026, no Capital Gain Incentive Fees have been payable as calculated under the Investment Advisory Agreement.

Professional Fees and General and Administrative Expenses

In general, we expect certain of our operating expenses, including professional fees and other general and administrative expenses to decline as a percentage of our total assets during periods of growth and increase as a percentage of our total assets during periods of asset declines.

The Administrator pays for certain expenses incurred by us. These expenses are subsequently reimbursed in cash. Total expenses reimbursed to the Administrator for both the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026 was $0.8 million. As of June 30, 2026, included in accounts payable and accrued expenses was $2.0 million of expenses paid on behalf of us by the Administrator.

Net Realized and Unrealized Gains and Losses

The following table summarizes our net realized and unrealized gains (losses) for the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026:


	Three months ended June 30, 2026		Period from December 31, 2025 (commencement of operations) to June 30, 2026
	(In thousands)

Net realized gain (loss) on foreign currency transactions	$	—	$	(66)
Net realized gain (loss) from forward currency contracts	19		19
Net realized gain (loss) on investment transactions	$	19	$	(47)
Unrealized appreciation from investments	$	921	$	235
Unrealized (depreciation) from investments	(717)		(4,126)
Unrealized appreciation (depreciation) from forward currency contracts	41		234
Unrealized appreciation (depreciation) on foreign currency translation	(106)		(232)
Net change in unrealized appreciation (depreciation) on investment transactions	$	139	$	(3,889)

For the three months ended June 30, 2026, we had net realized gains of less than $0.1 million driven by net realized gains recognized on the settlement of forward currency contracts. For the period from December 31, 2025 (commencement of operations) to June 30, 2026, we had net realized losses of less than $0.1 million driven by net realized losses recognized on the settlement of forward currency contracts and translation of foreign currency amounts and transactions into U.S. dollars.

For the three months ended June 30, 2026, we had $0.9 million in unrealized appreciation on 98 portfolio company investments, which was offset by $0.7 million in unrealized depreciation on 62 portfolio company investments. For the period from December 31, 2025 (commencement of operations) to June 30, 2026, we had $0.2 million in unrealized appreciation on 40 portfolio company investments, which was offset by $4.1 million in unrealized depreciation on 120 portfolio company investments.

Unrealized appreciation for the three months ended June 30, 2026 was primarily due to the reversal of previously recognized unrealized depreciation related to fair value adjustments related to market wide credit spread widening recognized during the quarter ended March 31, 2026. Unrealized appreciation for the period from December 31, 2025 (commencement of operations) to June 30, 2026 was primarily due to increases in the fair values of certain equity investments.

Unrealized depreciation for the three months ended June 30, 2026 primarily resulted from fair value adjustments to certain of our broadly syndicated loan portfolio company investments and from deterioration in the performance of debt and equity investments in a portfolio company, with the equity investment being moved to non-accrual status during the period. Unrealized depreciation for the period from December 31, 2025 (commencement of operations) to June 30, 2026 primarily resulted from (1) fair value adjustments across our portfolio company investments related to market wide credit spread widening during the three months ended March 31, 2026, primarily on our well-performing loans rated in our highest internal performance rating 4 and 5 categories, as defined below under the Portfolio Composition, Investment Activity and Yield” section, and (2) isolated deterioration in the performance of debt and equity investments in a portfolio company that was moved to non-accrual status.

Liquidity and Capital Resources

For the period from December 31, 2025 (commencement of operations) to June 30, 2026, we experienced a net decrease in cash, cash equivalents, foreign currencies, restricted cash, restricted cash equivalents and restricted foreign currencies of $7.7 million. During the period, cash used by operating activities was $141.2 million, primarily as a result of fundings of portfolio investments of $75.7 million and acquisition of subsidiaries of $73.0 million. Lastly, cash provided by financing activities was $133.5 million, primarily driven by proceeds from the issuance of common shares of $119.5 million and borrowings of debt of $101.9 million that were partially offset by debt repayments of $64.4 million and repurchases of common shares of $20.5 million.

As of June 30, 2026, we had cash, cash equivalents and foreign currencies of $5.0 million and restricted cash, restricted cash equivalents and restricted foreign currencies totaling $7.7 million. Cash, cash equivalents and foreign currencies are available to fund new investments, pay operating expenses and pay distributions. Restricted cash, restricted 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 credit facilities, as applicable.

On December 31, 2025, we completed the Initial Offering and accepted subscription agreements for total commitments of $106.8 million to purchase our common shares. On December 31, 2025, we received the Initial Offering subscription proceeds and issued 4,273,117 Common Shares at a price of $25.00 per share (the “Initial Closing”). In addition, concurrent with the Initial Closing, we issued 400 Common Shares at a price of $25.00 per share for proceeds totaling $10,000 in a private offering in connection with the issuance of the RF Notes (as defined in Note 7 of our Consolidated Financial Statements).

Revolving Debt Facilities

BANA Credit Facility - Effective December 31, 2025, we assumed, in connection with the GPIF S Purchase Agreement (as defined in Note 1 of our Consolidated Financial Statements), the BANA Credit Facility (as defined in Note 7 of our Consolidated Financial Statements), which, as of June 30, 2026, allowed us to borrow up to $425.0 million at any time outstanding, subject to leverage and borrowing base restrictions. As of June 30, 2026, we had $142.4 million outstanding under the BANA Credit Facility. As of June 30, 2026, subject to leverage and borrowing base restrictions, we had approximately $282.6 million of remaining commitments and $9.9 million of availability on the BANA Credit Facility.

Adviser Revolver - On December 23, 2025, we entered into the Adviser Revolver (as defined in Note 3 of our Consolidated Financial Statements) with GC Advisors. As of June 30, 2026, we were permitted to borrow up to $100.0 million at any one time outstanding under the Adviser Revolver. We entered into the Adviser Revolver in order to have the ability to borrow funds on a short-term basis and generally intend to repay borrowings under the Adviser Revolver within 30 to 45 days from which they are drawn. As of June 30, 2026, we had no amount outstanding under the Adviser Revolver.

Promissory Notes - OS Cayman Trust

Effective December 31, 2025, we entered into a $13.6 million OS Note with OS Cayman Trust and the Investment Adviser that the Company repaid in full on January 26, 2026.

Promissory Notes - REIT Funding

On December 31, 2025, concurrent with the Initial Closing, the Company issued and sold 400 RF Notes (as defined in Note 7 of our Consolidated Financial Statements). The RF Notes were issued in connection with the issuance of one Common Share to each accredited investor. As of June 30, 2026, the outstanding aggregate principal amount of the RF Note totaled $0.8 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 150% after such borrowing. On December 4, 2025, our sole shareholder approved the application of the reduced asset coverage requirements of Section 61(a)(2) of the 1940 Act and declined an offer by us to repurchase all our outstanding Common Shares. As a result of such approval, effective as of the date of our BDC election on December 31, 2025, our asset coverage requirement was reduced from 200% to 150%, or a ratio of total debt-to-equity of 2:1 as compared to a maximum of 1:1 under the 200% asset coverage requirement under the 1940 Act. We currently intend to target a GAAP debt-to-equity ratio between 0.85x to 1.25x. As of June 30, 2026, our asset coverage for borrowed amounts and GAAP debt-to-equity ratio that was 181.6% and 1.23x, respectively, and our GAAP debt-to-equity ratio, net, which reduces total debt by cash, cash equivalents and foreign currencies was 1.17x as of June 30, 2026.

As of June 30, 2026, we had outstanding commitments to fund investments totaling $32.4 million, including $17.1 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 as of June 30, 2026, subject to the terms of each loan’s respective credit agreement. A summary of maturity requirements for our principal borrowings as of June 30, 2026 is included in Note 7 of our consolidated financial statements. We did not have any other material contractual payment obligations as of June 30, 2026. As of June 30, 2026, we believe that we had sufficient assets and liquidity to adequately cover future obligations under our unfunded commitments based on the cash balances that we maintain, availability under our BANA Credit Facility and Adviser Revolver, ongoing principal repayments on debt investment assets.

Although we expect to fund the growth of our investment portfolio through the net proceeds from future securities offerings and future borrowings, to the extent permitted by the 1940 Act, we cannot assure you that our efforts to raise capital will be successful. In addition, from time to time, we can amend, 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 could receive smaller allocations, if any, on new investment opportunities under GC Advisors’ allocation policy.

Portfolio Composition, Investment Activity and Yield

As of June 30, 2026, we had investments in 158 portfolio companies, with a total fair value of $248.4 million.

The following table shows the asset mix of our new investment commitments for the three months ended June 30, 2026 and the period from December 31, 2025 (commencement of operations) to June 30, 2026:

(1)As of June 30, 2026, $40.7 million and $40.0 million of our loans at amortized cost and fair value, respectively, included a feature permitting a portion of interest due on such loan to be PIK interest. As of June 30, 2026, there were no loans with a PIK feature on non-accrual status.

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

As of June 30, 2026, we had no loans on non-accrual status and one preferred equity security on non-accrual status. Non-accrual investments as a percentage of total investments at both cost and fair value was 0.2%. As of June 30, 2026, the fair value of our debt investments as a percentage of the outstanding principal value was 98.4%.

The following table shows the weighted average rate, spread over the applicable base rate of floating rate investments and fees of middle-market (“MM”) investments originated and weighted average rate of sales and payoffs of portfolio companies during the three months ended June 30, 2026 and period from December 31, 2025 (commencement of operations) to June 30, 2026:



	Three months ended June 30, 2026		Period from December 31, 2025 (commencement of operations) to June 30, 20261

Weighted average rate of sales and payoffs of portfolio investments	7.3	%	7.7	%

(1)Excludes the Initial Assets acquired with proceeds from the Initial Closing on December 31, 2025.

As of June 30, 2026, 99.0% and 98.9% of our debt portfolio at fair value and at amortized cost, respectively, had interest rate floors that limited the minimum applicable interest rates on such loans.

As of June 30, 2026, the portfolio median2 earnings before interest, taxes, depreciation and amortization, or EBITDA, for our portfolio companies was $104.3 million. 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.

2 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, broadly syndicated loans and structured finance notes and (iii) portfolio companies with any loans on non-accrual status.

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 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 June 30, 2026 and December 31, 2025.

Distributions

We intend to make periodic regular and special distributions to our shareholders as determined by our Board. As a result, our distribution rates and payment frequency may vary from time to time and are not guaranteed. There is no assurance we will pay distributions in any particular amount, if at all. For additional details on distributions, see “Income taxes” in Note 2 to our consolidated financial statements included in this Quarterly Report.

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 taxation as a RIC. We cannot assure shareholders 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 shareholders for U.S. federal income tax purposes. Thus, the source of a distribution to our shareholders could be the original capital invested by the shareholder rather than our income or gains. Shareholders should read any written disclosure accompanying a distribution payment carefully and should not assume that the source of any distribution is our ordinary income or gains.

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

Related Party Transactions

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

•We entered into the Investment Advisory Agreement with GC Advisors. Mr. David Golub, our chief executive officer, is a manager of GC Advisors and owns an indirect pecuniary interest in GC Advisors.

•Golub Capital LLC provides us with the office facilities and administrative services necessary to conduct day-to-day operations pursuant to our Administration Agreement.

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

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

•We entered into the Expense Support Agreement (as defined in Note 3 of our Consolidated Financial Statements) with the Investment Adviser, pursuant to which the Investment Adviser may elect to pay certain expenses on our behalf, provided that no portion of the payment will be used to pay any interest expense or any of our distribution and/or shareholder servicing fees.

•On December 23, 2025, we entered into the Adviser Revolver with the Investment Adviser as the lender, pursuant to which the Investment Adviser has provided us with a $100.0 million unsecured, revolving line of credit for borrowings on a short-term basis to fulfill our working capital needs.

•On September 26, 2025 and December 19, 2025, GCP-PIF Feeder S (“GPIF S Feeder”), a Delaware statutory trust and indirectly wholly-owned subsidiary of GCP HS Fund purchased 400 Common Shares and 820,000 Common Shares, respectively, at a price of $25.00 per share. GPIF S Feeder and GCP HS Fund are managed by an affiliate of GC Advisors. The Board authorized the redemption of the 820,400 Common Shares held by GPIF S Feeder at a price of $25.00 per share effective December 31, 2025.

•On December 29, 2025, we entered into the share purchase and sale agreement, with GCP OS Cayman Trust, and the Investment Adviser, in which we acquired all of the assets and liabilities (the “Initial Assets”) of GPIF S Funding (“Funding”) and GPIF S Holdings (“Holdings”) through the purchase from the Seller of 100% of the beneficial interests in Funding and Holdings. The Initial Assets consisted of loans to 40 borrowers, cash and other assets.

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 Direct Lending Unlevered Corporation, or GDLCU, Golub Capital BDC 4, Inc., or GBDC 4, Golub Capital Private Credit Fund, or GCRED, and Golub Capital Private Income Fund I, or GPIF I, all of 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, GCRED and GPIF I. If GC Advisors and its affiliates determine that an investment is appropriate for us, GBDC, GDLC, GDLCU, GBDC 4, GCRED, GPIF I, 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 Delaware law.

Critical Accounting Policies

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

Fair Value Measurements

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

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

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

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

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

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

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

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

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

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

In certain cases, the inputs used to measure fair value could fall into different levels of the fair value hierarchy. In such cases, an asset’s or a liability’s categorization within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and we consider factors specific to the asset or liability. The Valuation Designee assesses the levels of assets and liabilities at each measurement date, and transfers between levels are recognized on the actual date of the event or change in circumstances that caused the transfers. There were no transfers among Level 1, 2 and 3 of the fair value hierarchy for assets and liabilities during the period from December 31, 2025 (commencement of operations) to June 30, 2026. 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.

Valuation of Investments

Level 1 investments are valued using quoted market prices. Level 2 investments are valued using market consensus prices that are corroborated by observable market data and quoted market prices for similar assets and liabilities. Level 3 investments are valued at fair value as determined in good faith by the Valuation Designee, and based on input of the Valuation Designee’s personnel and independent valuation firms that have been engaged by or at the direction of the Valuation Designee to assist in the valuation of each portfolio investment, without a readily available market quotation in accordance with the multi-step valuation process described above in “ — Fair Value Measurements”. For periods ending on or before December 31, 2025, at least every other quarter, the valuation for each portfolio investment (subject to a de minimis threshold) was reviewed by an independent valuation firm. This valuation process was conducted at the end of each fiscal quarter, with each portfolio investment being reviewed at least every other quarter (subject to a de minimis threshold) with approximately 50% (based on the fair value of portfolio company investments) of the Company’s valuations of debt and equity investments without readily available market quotations subject to review by an independent valuation firm. As of December 31, 2025, 100% of the investments included in the Initial Assets were subject to review by an independent valuation firm. For periods beginning after December 31, 2025, the valuation process is conducted on a monthly basis and this monthly valuation process begins with each portfolio investment being initially valued, based on the fair value methodology in accordance with ASC Topic 820 described below, either by (i) professionals of the Valuation Designee responsible for the valuation function or (ii) investment valuation firms that have been engaged to support the valuation of portfolio investments. Each month the valuation for each portfolio investment, or approximately 100% (based on the fair value of portfolio company investments) of our debt and equity investments without readily available market quotations (subject to a de minimis threshold) was either (i) performed by or (ii) reviewed by an independent valuation firm. As of June 30, 2026, $36,372 and $212,074 of investments were valued using Level 2 inputs and Level 3 inputs, respectively. As of June 30, 2026, all forward currency contracts were valued using Level 2 inputs and all money market funds included in cash equivalents and restricted cash equivalents were valued using Level 1 inputs.

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

In addition, for certain debt investments, the Valuation Designee could base its valuation on indicative bid and ask prices provided by an independent third-party pricing service or directly from independent brokers. Bid prices reflect the highest price that we and others could be willing to pay. Ask prices represent the lowest price that we and others could be willing to accept. The Valuation Designee generally uses the midpoint of the independent third-party market “bid” and “ask” quotes to determine the value of our portfolio investments but may use another value if the Valuation Designee determines it better represents the investment’s fair value. While market price quotes from third-party pricing sources may be available, the Valuation Designee has the discretion to seek and utilize independent quotes from independent broker dealers to determine the fair value of the applicable portfolio investment. The Valuation Designee may obtain and consider both “bid” and “ask” quotes from either independent third-party vendors or directly from independent brokers.

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

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

In connection with each sale of our Common Shares, we make a determination that we are not selling Common Shares at a price below the then-current net asset value per share of common shares 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 Shares 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 Shares 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 Shares and ending on the date on which the offering price for such month is determined; and

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

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 Statement of Financial Condition due to their short maturity.

Revenue Recognition:

Our revenue recognition policies are as follows:

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

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

Non-accrual Investments: Loans may be left on accrual status while we are pursuing repayment of the loan. Management reviews all loans that become past due 90 days or more on principal and interest or when there is reasonable doubt that principal or interest will be collected for possible placement on non-accrual status. We generally reverse accrued interest when a loan is placed on non-accrual. Additionally, any original issue discount and market discount are no longer accreted to interest income as of the date the loan is placed on non-accrual status. Interest payments received on non-accrual loans could be recognized as income or applied to principal depending upon management’s judgment. We restore non-accrual loans to accrual status when past due principal and interest is paid and, in our management’s judgment, are likely to remain current. As of June 30, 2026, we had no portfolio company loans on non-accrual status. We review all preferred equity securities accruing contractual PIK dividend income to determine if there is reasonable doubt that amortized cost or capitalized PIK and non-cash dividend income will be collected, for possible placement on non-accrual status. When a preferred equity security is placed on non-accrual status, the contractual PIK dividend provision is no longer accrued to dividend income as of the date the preferred equity security is placed on non-accrual status. As of June 30, 2026, there was one preferred equity security on non-accrual status with a fair value of $0.4 million.

Income taxes: We intend to elect to be treated as a RIC under Subchapter M of the Code and will 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 shareholders 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 shareholders, which will generally relieve us from U.S. federal income taxes.

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 could then be required to incur a 4% excise tax on such income. To the extent that we determine that our estimated current year annual taxable income, determined on a calendar year basis, could exceed estimated current calendar year dividend distributions, we accrue excise tax, if any, on estimated excess taxable income as taxable income is earned. For the period from December 31, 2025 (commencement of operations) to June 30, 2026, we did not incur any U.S. federal excise tax.

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.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

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

Valuation Risk. We will 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 will value these portfolio investments at fair value as determined in good faith by our Valuation Designee, subject to oversight by the Board in accordance with our valuation policy and process. There is no single standard for determining fair value. As a result, determining fair value requires that judgment be applied to the specific facts and circumstances of each investment while employing a consistently applied valuation process for the investments we hold. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of our investments could fluctuate from period to period, if we were to sell or liquidate a portfolio investment, including, for example, in a forced or liquidation sale, we could realize significantly less than the value at which we have recorded it.

Interest Rate Risk. Many of the loans in our portfolio have floating interest rates, and we expect that our loans in the future could also have floating interest rates. These loans are usually based on floating SOFR or another base rate and typically have interest rate reset provisions that adjust applicable interest rates under such loans to current market rates on a daily, monthly, quarterly, semi-annual or annual basis. The loans that are subject to floating SOFR or another base rate are also typically subject to a minimum base rate, or floor, that we charge on our loans if the current market rates are below the respective floors. As of June 30, 2026, the weighted average floor on loans subject to floating interest rates was 0.70%. The BANA Credit Facility has a floating rate applicable to the currency of such borrowing. The Adviser Revolver has a floating interest rate provision equal to the short-term Applicable Federal Rate. We may 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. 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 June 30, 2026 was to remain constant and that we took no actions to alter interest rate sensitivity as of such date, the following table shows the annualized impact of hypothetical base rate changes in interest rates.


Change in interest rates	Increase (decrease) in interest income(1)		Increase (decrease) in interest expense		Net increase (decrease) in investment income
	(In thousands)
Down 200 basis points	$	(4,912)	$	(2,848)	$	(2,064)
Down 150 basis points	(3,709)		(2,136)		(1,573)
Down 100 basis points	(2,476)		(1,424)		(1,052)
Down 50 basis points	(1,237)		(712)		(525)
Up 50 basis points	1,237		712		525
Up 100 basis points	2,476		1,424		1,052
Up 150 basis points	3,713		2,136		1,577
Up 200 basis points	4,951		2,848		2,103

(1) Assumes applicable three-month base rate as of June 30, 2026, with the exception of SONIA and Prime that utilizes the June 30, 2026 rate.

Although we believe that this analysis is indicative of our sensitivity to interest rate changes as of June 30, 2026, it does not adjust for changes in the credit market, credit quality, the size and composition of the assets in our portfolio and other business developments, including borrowings under the Adviser Revolver or other borrowings, that could affect net increase in net assets resulting from operations, or net income. Accordingly, we can offer no assurances that actual results would not differ materially from the analysis above.

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 could insulate us against adverse changes in interest rates, they could also limit our ability to participate in the benefits of lower interest rates with respect to the investments in our portfolio with fixed interest rates.

Item 4. Controls and Procedures.

As of June 30, 2026 (the end of the period covered by this report), management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act). Based on that evaluation, our management, including the chief executive officer and chief financial officer, concluded that, at the end of such period, our disclosure controls and procedures were effective and provided reasonable assurance that information required to be disclosed in our periodic SEC filings is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure. Notwithstanding the foregoing, a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that it will detect or uncover failures within the Company to disclose material information otherwise required to be set forth in the Company’s periodic reports.

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