CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This report contains forward-looking statements that involve substantial risks and uncertainties. Such statements involve known and unknown risks, uncertainties and other factors and undue reliance should not be placed thereon. These forward-looking statements are not historical facts, but rather are based on current expectations, estimates and projections about Blackstone Secured Lending Fund (together, with its consolidated subsidiaries, the “Company,” “we,” “us,” or “our”), our current and prospective portfolio investments, our industry, our beliefs and opinions, and our assumptions. Words such as “anticipates,” “expects,” “intends,” “plans,” “will,” “may,” “continue,” “believes,” “seeks,” “estimates,” “would,” “could,” “should,” “targets,” “projects,” “outlook,” “potential,” “predicts” and variations of these words and similar expressions are intended to identify forward-looking statements. These statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond our control and difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements, including without limitation:

•our future operating results;

•our business prospects and the prospects of the companies in which we may invest;

•the impact of the investments that we expect to make;

•our ability to raise sufficient capital and buy back shares to execute our investment strategy;

•general economic, logistical and political trends and other external factors, including inflation and recent supply chain disruptions and their impacts on our portfolio companies and on the industries in which we invest;

•the ability of our portfolio companies to achieve their objectives;

•our current and expected financing arrangements and investments;

•changes in the general interest rate environment;

•the adequacy of our cash resources, financing sources and working capital;

•the timing and amount of cash flows, distributions and dividends, if any, from our portfolio companies;

•our contractual arrangements and relationships with third parties;

•actual and potential conflicts of interest with Blackstone Credit BDC Advisors LLC (the “Adviser”) or any of its affiliates;

•the dependence of our future success on the general economy and its effect on the industries in which we may invest;

•our use of financial leverage including the use of borrowed money to finance a portion of our investments and the availability of equity and debt capital on favorable terms or at all;

•our business prospects and the prospects of our portfolio companies, including our and their ability to effectively respond to the macroeconomic effects from adverse public health developments;

•the ability of the Adviser to source suitable investments for us and to monitor and administer our investments;

•the impact of future acquisitions and divestitures;

•the ability of the Adviser or its affiliates to attract and retain highly talented professionals;

•general price and volume fluctuations in the stock market;

•our ability to maintain our qualification as a regulated investment company and as a business development company (“BDC”);

•the impact on our business of U.S. and international financial reform legislation, rules and regulations;

•the effect of changes to tax legislation and our tax position; and

•the tax status of the enterprises in which we may invest.

Although we believe that the assumptions on which these forward-looking statements are based are reasonable, any of those assumptions could prove to be inaccurate, and as a result, the forward-looking statements based on those assumptions also could be inaccurate. In light of these and other uncertainties, the inclusion of any projection or forward-looking statement in this report should not be regarded as a representation by us that our plans and objectives will be achieved. These risks and uncertainties include those described or identified in the section entitled “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2023 as updated by the Company's periodic filings with the United States Securities and Exchange Commission (the “SEC”). These projections and forward-looking statements apply only as of the date of this report. Moreover, we assume no duty and do not undertake to update the forward-looking statements, except as required by applicable law. You are advised to consult any additional disclosures that we make directly to you or through reports that we have filed or in the future file with the SEC including annual reports on Form 10-K, registration statements on Form N-2, quarterly reports on Form 10-Q and current reports on Form 8-K.

Because we are an investment company, the forward-looking statements and projections contained in this report are excluded from the safe harbor protection provided by Section 21E of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”).

(1)Unless otherwise indicated, all debt and equity investments held by the Company (which such term “Company” shall include the Company’s consolidated subsidiaries for purposes of this Consolidated Schedule of Investments) are denominated in dollars. As of March 31, 2024, the Company had investments denominated in Canadian Dollars (CAD), Euros (EUR), British Pounds (GBP), Danish Krone (DKK), Swedish Krona (SEK), Norwegian Krone (NOK), and Australian Dollars (AUD). All debt investments are income producing unless otherwise indicated. All equity investments are non-income producing unless otherwise noted. Certain portfolio company investments are subject to contractual restrictions on sales. The total par amount (in thousands) is presented for debt investments, while the number of shares or units (in whole amounts) owned is presented for equity investments. Each of the Company’s investments is pledged as collateral, under one or more of its credit facilities unless otherwise indicated.

(2)Variable rate loans to the portfolio companies bear interest at a rate that is determined by reference to either Canadian Dollar Offered Rate (“CDOR” or “C”), Sterling Overnight Interbank Average Rate (“SONIA” or “S”), Euro Interbank Offer Rate (“Euribor” or “E”), Secured Overnight Financing Rate (“SOFR”), Stockholm Interbank Offered Rate (“STIBOR” or “ST”), Copenhagen Interbank Offered Rate (“CIBOR” or “CI”), Norwegian Interbank Offered Rate (“NIBOR” or “N”), Australian Bank Bill Swap Bid Rate (“BBSY” or “BB”),or an alternate base rate (commonly based on the Federal Funds Rate (“F”) or the U.S. Prime Rate (“P”)), which generally resets periodically. For each loan, the Company has indicated the reference rate used and provided the spread and the interest rate in effect as of March 31, 2024. Variable rate loans typically include an interest reference rate floor feature. As of March 31, 2024, 92.9% of the debt portfolio at fair value had an interest rate floor above zero. Rates on equity instruments represents contractual dividend rates on certain preferred equity positions.

(3)The cost represents the original cost adjusted for the amortization of discounts and premiums, as applicable, on debt investments using the effective interest method in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

(4)These investments were valued using unobservable inputs and are considered Level 3 investments. Fair value was determined in good faith by or under the direction of the Board of Trustees (see Note 2), pursuant to the Company’s valuation policy.

(5)These investments are not pledged as collateral under any of the Company's credit facilities. For other debt investments that are pledged to the Company's credit facilities, a single investment may be divided into parts that are individually pledged as collateral to separate credit facilities. Any other debt investments listed above are pledged to financing facilities and are not available to satisfy the creditors of the Company.

(6)The investment is not a qualifying asset under Section 55(a) of the Investment Company Act of 1940, as amended (together with the rules and regulations promulgated thereunder, the “1940 Act”). The Company may not acquire any non-qualifying asset unless, at the time of acquisition, qualifying assets represent at least 70% of the Company’s total assets. As of March 31, 2024, non-qualifying assets represented 11.2% of total assets as calculated in accordance with regulatory requirements.

(7)Position or portion thereof is an unfunded commitment, and no interest is being earned on the unfunded portion, although the investment may be subject to unused commitment fees.

(1)Unless otherwise indicated, all debt and equity investments held by the Company (which such term “Company” shall include the Company’s consolidated subsidiaries for purposes of this Consolidated Schedule of Investments) are denominated in dollars. As of December 31, 2023, the Company had investments denominated in Canadian Dollars (CAD), Euros (EUR), British Pounds (GBP), Danish Krone (DKK), Swedish Krona (SEK), and Norwegian Krone (NOK). All debt investments are income producing unless otherwise indicated. All equity investments are non-income producing unless otherwise noted. Certain portfolio company investments are subject to contractual restrictions on sales. The total par amount (in thousands) is presented for debt investments, while the number of shares or units (in whole amounts) owned is presented for equity investments. Each of the Company’s investments is pledged as collateral, under one or more of its credit facilities unless otherwise indicated.

(2)Variable rate loans to the portfolio companies bear interest at a rate that is determined by reference to either Canadian Dollar Offered Rate (“CDOR” or “C”), Sterling Overnight Interbank Average Rate (“SONIA” or “S”), Euro Interbank Offer Rate (“Euribor” or “E”), Secured Overnight Financing Rate (“SOFR”), Stockholm Interbank Offered Rate (“STIBOR” or “ST”), Copenhagen Interbank Offered Rate (“CIBOR” or “CI”), Norwegian Interbank Offered Rate (“NIBOR” or “N”), or an alternate base rate (commonly based on the Federal Funds Rate (“F”) or the U.S. Prime Rate (“P”)), which generally resets periodically. For each loan, the Company has indicated the reference rate used and provided the spread and the interest rate in effect as of December 31, 2023. Variable rate loans typically include an interest reference rate floor feature. As of December 31, 2023, 93.7% of the debt portfolio at fair value had an interest rate floor above zero. Rates on equity instruments represents contractual dividend rates on certain preferred equity positions.

(3)The cost represents the original cost adjusted for the amortization of discounts and premiums, as applicable, on debt investments using the effective interest method in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

(4)These investments were valued using unobservable inputs and are considered Level 3 investments. Fair value was determined in good faith by or under the direction of the Board of Trustees (see Note 2), pursuant to the Company’s valuation policy.

(5)These investments are not pledged as collateral under any of the Company's credit facilities. For other debt investments that are pledged to the Company's credit facilities, a single investment may be divided into parts that are individually pledged as collateral to separate credit facilities. Any other debt investments listed above are pledged to financing facilities and are not available to satisfy the creditors of the Company.

(6)The investment is not a qualifying asset under Section 55(a) of the Investment Company Act of 1940, as amended (together with the rules and regulations promulgated thereunder, the “1940 Act”). The Company may not acquire any non-qualifying asset unless, at the time of acquisition, qualifying assets represent at least 70% of the Company’s total assets. As of December 31, 2023, non-qualifying assets represented 11.0% of total assets as calculated in accordance with regulatory requirements.

(7)Position or portion thereof is an unfunded commitment, and no interest is being earned on the unfunded portion, although the investment may be subject to unused commitment fees. Negative cost and fair value results from unamortized fees, which are capitalized to the investment cost. The unfunded commitment may be subject to a commitment termination date that may expire prior to the maturity date stated. See below for more information on the Company’s unfunded commitments:

Note 1. Organization

Blackstone Secured Lending Fund (together with its consolidated subsidiaries, the “Company”), is a Delaware statutory trust formed on March 26, 2018, and structured as an externally managed, non-diversified, closed-end management investment company. On October 26, 2018, the Company elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (together with the rules and regulations promulgated thereunder, the “1940 Act”). In addition, the Company has elected to be treated for U.S. federal income tax purposes, and intends to qualify annually, as a regulated investment company (a “RIC”), under Subchapter M of the Internal Revenue Code of 1986, as amended (together with the rules and regulations promulgated thereunder, the “Code”).

The Company is externally managed by Blackstone Credit BDC Advisors LLC (the “Adviser”) an affiliate of Blackstone Alternative Credit Advisors LP (the “Administrator” and, collectively with its affiliates in the credit, asset-based finance, and insurance asset management business unit of Blackstone Inc. (“Blackstone”), “Blackstone Credit & Insurance,” or “BXCI”). The Administrator provides certain administrative and other services necessary for the Company to operate pursuant to an administration agreement (the “Administration Agreement”). References herein to information about Blackstone Credit & Insurance from December 31, 2023 or prior refers solely to the Adviser and Blackstone Alternative Credit Advisors LP, collectively with their credit-focused affiliates within Blackstone Credit & Insurance.

The Company’s investment objectives are to generate current income and, to a lesser extent, long-term capital appreciation. The Company seeks to achieve its investment objectives primarily through originated loans and other securities, including syndicated loans, of private U.S. companies, typically in the form of first lien senior secured and unitranche loans (including first out/last out loans), and to a lesser extent, second lien, third lien, unsecured and subordinated loans and other debt and equity securities.

The Company commenced its loan origination and investment activities on November 20, 2018.

On October 28, 2021, the Company priced its initial public offering (“IPO”), and the Company's common shares of beneficial interest (“Common Shares”) began trading on the New York Stock Exchange (“NYSE”). See “Note 8. Net Assets” for further details.

Note 2. Significant Accounting Policies

Basis of Presentation

The condensed consolidated financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States (“GAAP”). As an investment company, the Company applies the accounting and reporting guidance in Accounting Standards Codification (“ASC”) Topic 946, “Financial Services – Investment Companies” (“ASC 946”) issued by the Financial Accounting Standards Board (“FASB”).

The interim condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 6 and Article 10 of Regulation S-X. Accordingly, certain disclosures accompanying the annual consolidated financial statements prepared in accordance with GAAP are omitted. In the opinion of management, all adjustments considered necessary for the fair presentation of the condensed consolidated financial statements for the interim period presented, have been included. The current period’s results of operations will not necessarily be indicative of results that ultimately may be achieved for the fiscal year ending December 31, 2024.

All intercompany balances and transactions have been eliminated.

Certain prior period information has been reclassified to conform to the current period presentation.

Use of Estimates

The preparation of condensed 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 condensed consolidated financial statements. Such amounts could differ from those estimates and such differences could be material. Assumptions and estimates regarding the valuation of investments involve a higher degree of judgment and complexity and these assumptions and estimates may be significant to the condensed consolidated financial statements. Actual results may ultimately differ from those estimates.

Consolidation

As provided under ASC 946, the Company will 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.

The Company consolidated the results of the Company’s wholly-owned subsidiaries which are considered to be investment companies. As of March 31, 2024 and December 31, 2023, the Company's consolidated subsidiaries were BGSL Jackson Hole Funding LLC (“Jackson Hole Funding”), BGSL Breckenridge Funding LLC (“Breckenridge Funding”), BGSL Big Sky Funding LLC (“Big Sky Funding”), BGSL Investments LLC (“BGSL Investments”), BXSL Associates GP (Lux) S.à r.l, BXSL Direct Lending (Lux) SCSp, BXSL C-1 LLC, and BXSL C-2 Funding LLC.

Cash and Cash Equivalents

Cash and cash equivalents consist of demand deposits and highly liquid investments, such as money market funds, with original maturities of three months or less. Cash and cash equivalents are carried at cost, which approximates fair value. The Company deposits its cash and cash equivalents with financial institutions and, at times, may exceed the Federal Deposit Insurance Corporation insured limit.

Investments

Investment transactions are recorded on a trade date basis.

Realized gains or losses are measured by the difference between the net proceeds received (excluding prepayment fees, if any) and the amortized cost basis of the investment using the specific identification method without regard to unrealized gains or losses previously recognized, and include investments charged off during the period, net of recoveries, and is recorded within Net realized gain (loss) on the Condensed Consolidated Statements of Operations.

The net change in unrealized gains or losses primarily reflects the change in investment values, including the reversal of previously recorded unrealized gains or losses with respect to investments realized during the period, and is recorded within Net change in unrealized appreciation (depreciation) on the Condensed Consolidated Statements of Operations.

Valuation of Investments

The Company is required to report its investments, including those for which current market values are not readily available, at fair value.

The Company values its investments in accordance with ASC 820, Fair Value Measurements (“ASC 820”), which defines fair value as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the applicable measurement date, and Rule 2a-5 under the 1940 Act.

Under ASC 820, fair value is based on observable market prices or parameters or derived from such prices or parameters when such quotations are readily available. In accordance with Rule 2a-5 under the 1940 Act, fair value means the value of a portfolio investment for which market quotations are not readily available. A market quotation is “readily available” only when it is a quoted price (unadjusted) in active markets for identical instruments that a fund can access at the measurement date, provided that such a quotation is not considered to be readily available if it is not reliable.

Where prices or inputs are not available or, in the judgment of the Board, with assistance of the Adviser, the Audit Committee and independent valuation firm(s), determine to be not reliable, valuation techniques based on the facts and circumstances of the particular investment will be utilized. These valuation approaches involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the investments or market and the investments’ complexity. In the absence of observable, reliable market prices, the Company values its investments using various valuation methodologies applied on a consistent basis.

An enterprise value (“EV”) analysis is generally performed to determine the value of equity investments, control debt investments and non-control debt investments that are credit-impaired, and to determine if debt investments are credit-impaired. The Adviser will generally utilize approaches including the market approach, the income approach or both approaches, as appropriate, when calculating EV. The primary method for determining EV for non-control investments, and control investments without reliable projections, uses a multiple analysis whereby appropriate multiples are applied to the portfolio company’s earnings before interest, taxes, depreciation and amortization (“EBITDA”) or another key financial metric (e.g., such as revenues, cash flows or net income) (“Performance Multiple”). Performance Multiples are typically determined based upon a review of publicly-traded comparable companies and market comparable transactions, if any. The second method for determining EV (and primary method for control investments with reliable projections) uses a discounted cash flow analysis whereby future expected cash flows and the anticipated terminal value of the portfolio company are discounted to determine a present value using estimated discount rates. The income approach is generally used when the Adviser has visibility into the long term projected cash flows of a portfolio company.

If debt investments are credit-impaired, which occurs when there is insufficient coverage under the enterprise value analysis through the respective investment’s position in the capital structure, the Adviser generally uses the enterprise value “waterfall” approach or a recovery method (if a liquidation or restructuring is deemed likely) to determine fair value. For debt investments that are not determined to be credit-impaired, the Adviser generally uses a market interest rate yield analysis to determine fair value. To determine fair value using a yield analysis, the expected cash flows are projected based on the contractual terms of the debt security and discounted back to the measurement date based on a market yield. A market yield is determined based upon an assessment of current and expected market yields for similar investments and risk profiles. The Company considers the current contractual interest rate, the maturity and other terms of the investment relative to risk of the company and the specific investment. A key determinant of risk, among other things, is the leverage through the investment relative to the enterprise value of the portfolio company. As debt investments held by the Company are substantially illiquid with no active transaction market, the Company depends on primary market data, including newly funded transactions, as well as secondary market data with respect to high yield debt instruments and syndicated loans, as inputs in determining the appropriate market yield, as applicable. The fair value of loans with call protection is generally capped at par plus applicable prepayment premium in effect at the measurement date.

ASC 820 prioritizes the use of observable market prices derived from such prices. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The levels used for classifying investments are not necessarily an indication of the risk associated with investing in these securities. The three levels of the fair value hierarchy are as follows:

•Level 1: Inputs to the valuation methodology are quoted prices available in active markets for identical instruments as of the reporting date. The types of financial instruments included in Level 1 include unrestricted securities, including equities and derivatives, listed in active markets.

•Level 2: Inputs to the valuation methodology are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date. The types of financial instruments in this category include less liquid and restricted securities listed in active markets, securities traded in other than active markets, government and agency securities and certain over-the-counter derivatives where the fair value is based on observable inputs.

•Level 3: Inputs to the valuation methodology are unobservable and significant to overall fair value measurement. The inputs into the determination of fair value require significant management judgment or estimation. Financial instruments that are included in this category include debt and equity investments in privately held entities, collateralized loan obligations (“CLOs”) and certain over-the-counter derivatives where the fair value is based on unobservable inputs.

(in thousands, except share amounts, per share data, percentages and as otherwise noted)

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the overall fair value measurement. The Board’s assessment, with the assistance of the Adviser, the Audit Committee and independent valuation firm(s), of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment. Transfers between levels, if any, are recognized at the beginning of the quarter in which the transfer occurs.

The Company evaluates the source of the inputs, including any markets in which its investments are trading (or any markets in which securities with similar attributes are trading), in determining fair value. When an investment is valued based on prices provided by reputable dealers or pricing services (that is, broker quotes), the Company subjects those prices to various criteria in making the determination as to whether a particular investment would qualify for treatment as a Level 2 or Level 3 investment.

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 Company’s investments may fluctuate from period to period, and these differences could be material. Additionally, the fair value of the Company’s investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that the Company may ultimately realize. Further, such investments are generally subject to legal and other restrictions on resale or otherwise are less liquid than publicly-traded securities. If the Company was required to liquidate a portfolio investment in a forced or liquidation sale, it could realize significantly less than the value at which the Company has recorded it. In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the unrealized gains or losses reflected in the valuations currently assigned. See “Item 2. Management’s Discussion and Analysis of Financial Conditions and Results of Operations—Critical Accounting Estimates.”

Receivables/Payables From Investments Sold/Purchased

Receivables/payables from investments sold/purchased consist of amounts receivable to or payable by the Company for transactions that have not settled at the reporting date.

Derivative Instruments

The Company recognizes all derivative instruments as assets or liabilities at fair value in its condensed consolidated financial statements. Derivative contracts entered into by the Company are not designated in hedge accounting relationships and all changes in fair value are recognized through current period gains or losses.

In the normal course of business, the Company has commitments and risks resulting from its investment transactions, which may include those involving derivative instruments. Derivative instruments are measured in terms of the notional contract amount and derive their value based upon one or more underlying instruments. While the notional amount gives some indication of the Company’s derivative activity, it generally is not exchanged, but is only used as the basis on which interest and other payments are exchanged. Derivative instruments are subject to various risks similar to non-derivative instruments including market, credit, liquidity, and operational risks. The Company manages these risks on an aggregate basis as part of its risk management process.

Forward Purchase Agreement

Forward purchase agreements are recognized at fair value through current period gains or losses on the date on which the contract is entered into and are subsequently re-measured at fair value. All forward purchase agreements are carried as assets when fair value is positive and as liabilities when fair value is negative. A forward purchase agreement is derecognized when the obligation specified in the contract is discharged, canceled or expired.

Foreign Currency Transactions

Amounts denominated in foreign currencies are translated into U.S. dollars on the following basis: (i) investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates effective on the last business day of the period; and (ii) purchases and sales of investments, borrowings and repayments of such borrowings, income, and expenses denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates prevailing on the transaction dates.

The Company includes net changes in fair values on investments held resulting from foreign exchange rate fluctuations in Translation of assets and liabilities in foreign currencies on the Condensed Consolidated Statements of Operations, if any. Foreign security and currency translations may involve certain considerations and risks not typically associated with investing in U.S. companies and U.S. government securities. 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.

Revenue Recognition

Interest Income

Interest income is recorded on an accrual basis and includes the accretion of discounts and amortizations of premiums. Discounts from and premiums to par value on debt investments purchased are accreted/amortized into interest income over the life of the respective security using the effective interest method. The amortized cost of debt investments represents the original cost, including loan origination fees and upfront fees received that are deemed to be an adjustment to yield, adjusted for the accretion of discounts and amortization of premiums, if any. Upon prepayment of a loan or debt security, any prepayment premiums, unamortized upfront loan origination fees and unamortized discounts are recorded as interest income in the current period. For the three months ended March 31, 2024 and 2023, the Company recorded $1.9 million and $0.4 million, respectively, in non-recurring interest income (e.g., prepayment premiums, accelerated accretion of upfront loan origination fees and unamortized discounts).

PIK Income

The Company has loans in its portfolio that contain payment-in-kind (“PIK”) provisions. PIK represents interest that is accrued and recorded as interest income at the contractual rates, increases the loan principal on the respective capitalization dates, and is generally due at maturity. Such income is included in payment-in-kind interest income in the Condensed Consolidated Statements of Operations. If at any point the Company believes PIK is not expected to be realized, the investment generating PIK will be placed on non-accrual status. When a PIK investment is placed on non-accrual status, the accrued, uncapitalized interest is generally reversed through payment-in-kind interest income. To satisfy the Company’s annual RIC distribution requirements, this non-cash source of income must be included in determining the amounts to be paid out to shareholders in the form of dividends, even though the Company has not yet collected cash.

Dividend Income

Dividend income on preferred equity securities is recorded on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. 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.

Fee Income

The Company may receive various fees in the ordinary course of business such as structuring, consent, waiver, amendment, syndication and other miscellaneous fees as well as fees for managerial assistance rendered by the Company to the portfolio companies. Such fees are recognized as income when earned or the services are rendered.

(Unaudited)

(in thousands, except share amounts, per share data, percentages and as otherwise noted)

Non-Accrual Income

Loans are generally placed on non-accrual status when there is reasonable doubt whether principal or interest will be collected in full. Accrued interest is generally reversed when a loan is placed on non-accrual status. Additionally, any original issue discount and market discount are no longer accreted to interest income as of the date the loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. Non-accrual loans are restored to accrual status when past due principal and interest is paid current and, in management’s judgment, are likely to remain current. Management may make exceptions to this treatment and determine to not place a loan on non-accrual status if the loan has sufficient collateral value and is in the process of collection.

For further information regarding the non-accrual status of investments refer to “Note 4. Investments”.

Organization Expenses and Offering Expenses

The Company records expenses related to public equity offerings as a reduction of capital upon completion of an offering of registered securities. The costs associated with any renewals of a shelf registration statement will be expensed as incurred.

Deferred Financing Costs and Debt Issuance Costs

Deferred financing and debt issuance costs represent fees and other direct incremental costs incurred in connection with the Company’s borrowings. These expenses are deferred and amortized into interest expense over the life of the related debt instrument. Deferred financing costs related to revolving credit facilities are presented separately as an asset on the Company’s Condensed Consolidated Statements of Assets and Liabilities. Debt issuance costs related to any issuance of installment debt or notes are presented net against the outstanding debt balance of the related security.

Income Taxes

The Company has elected to be treated as a BDC under the 1940 Act. The Company also has elected to be treated as a RIC under the Code. So long as the Company maintains its status as a RIC, it generally will not pay corporate-level U.S. federal income taxes on any ordinary income or capital gains that it distributes at least annually to its shareholders as dividends. Rather, any tax liability related to income earned and distributed by the Company would represent obligations of the Company’s investors and would not be reflected in the condensed consolidated financial statements of the Company.

The Company evaluates tax positions taken or expected to be taken in the course of preparing its condensed consolidated financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are reserved and recorded as a tax benefit or expense in the current year. All penalties and interest associated with income taxes are included in income tax expense. Conclusions regarding tax positions are subject to review and may be adjusted at a later date based on factors including, but not limited to, on-going analyses of tax laws, regulations and interpretations thereof.

To qualify for and maintain qualification as a RIC, the Company must, among other things, meet certain source-of-income and asset diversification requirements. In addition, to qualify for taxation as a RIC, the Company must distribute to its shareholders, for each taxable year, at least 90% of the sum of (i) its “investment company taxable income” for that year (without regard to the deduction for dividends paid), which is generally its ordinary income plus the excess, if any, of its realized net short-term capital gains over its realized net long-term capital losses and (ii) its net tax-exempt income.

In addition, based on the excise tax distribution requirements, the Company is subject to a 4% nondeductible federal excise tax on certain undistributed income unless the Company distributes in a timely manner in each taxable year an amount at least equal to the sum of (i) 98% of its ordinary income for the calendar year, (ii) 98.2% of its capital gain net income (both long-term and short-term) for the one-year period ending October 31 in that calendar year and (iii) any income realized, but not distributed, in prior years. For this purpose, however, any ordinary income or capital gain net income retained by the Company that is subject to corporate income tax is considered to have been distributed.

For the three months ended March 31, 2024 and 2023, the Company incurred $3.4 million and $2.6 million, respectively, of U.S. federal excise tax.

Distributions

To the extent that the Company has taxable income available, the Company intends to make quarterly distributions to its shareholders. Distributions to shareholders are recorded on the record date. All distributions will be paid at the discretion of the Board and will depend on the Company’s earnings, financial condition, maintenance of the Company's tax treatment as a RIC, compliance with applicable BDC regulations and such other factors as the Board may deem relevant from time to time.

Recent Accounting Pronouncements

In June 2022, the FASB issued Accounting Standards Update (“ASU”) 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions” (“ASU 2022-03”), which clarifies guidance for fair value measurement of an equity security subject to a contractual sale restriction and establishes new disclosure requirements for such equity securities. ASU 2022-03 is effective for fiscal years beginning after December 15, 2023 and for interim periods within those fiscal years, and has been adopted by the Company beginning with the condensed consolidated financial statements as of and for the three months ended March 31, 2024. The adoption of this guidance did not have a material impact on the Company’s condensed consolidated financial statements.

In November 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” (“ASU 2023-07”). ASU 2023-07 enhances the disclosures required for reportable segments on an annual and interim basis. ASU 2023-07 is effective on a retrospective basis for annual periods beginning after December 15, 2023, for interim periods within fiscal years beginning after December 15, 2024, and early adoption is permitted. The Company does not expect the adoption of ASU 2023-07 to have a material impact on its consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” (“ASU 2023-09”). ASU 2023-09 requires additional disaggregated disclosures on the entity’s effective tax rate reconciliation and additional details on income taxes paid. ASU 2023-09 is effective on a prospective basis, with the option for retrospective application, for annual periods beginning after December 15, 2024 and early adoption is permitted. The Company does not expect the adoption of ASU 2023-09 to have a material impact on its consolidated financial statements.

Note 3. Agreements and Related Party Transactions

Investment Advisory Agreement

On October 1, 2018, the Company entered into the original investment advisory agreement with the Adviser. The Adviser is responsible for originating prospective investments, conducting research and due diligence investigations on potential investments, analyzing investment opportunities, negotiating and structuring the Company’s investments and monitoring its investments and portfolio companies on an ongoing basis.

On October 18, 2021, the Company entered into an amended and restated investment advisory agreement (as amended and restated, the “Investment Advisory Agreement”), pursuant to which the Adviser manages the Company on a day-to-day basis. The Investment Advisory Agreement is substantially the same as the prior investment advisory agreement except, following the IPO, the incentive fee on income became subject to a twelve-quarter lookback quarterly hurdle rate of 1.50% as opposed to a single quarter measurement and became subject to an Incentive Fee Cap (as defined below) based on the Company’s Cumulative Net Return (as defined below). The amendment to the Investment Advisory Agreement does not result in higher fees (on a cumulative basis) payable to the Adviser than the fees that would have otherwise been payable to the Adviser under the original investment advisory agreement.

(in thousands, except share amounts, per share data, percentages and as otherwise noted)

The Company pays the Adviser a fee for its services under the Investment Advisory Agreement consisting of two components: a management fee and an incentive fee. The cost of both the management fee and the incentive fee is borne by the shareholders. The initial term of the Investment Advisory Agreement was two years from October 1, 2018, and on May 6, 2020 and May 6, 2021, it was renewed and approved by the Board, including a majority of trustees who are not parties to the Investment Advisory Agreement or “interested persons” (as such term is defined in Section 2(a)(19) of the 1940 Act) (the “Independent Trustees”), for a one-year period. On October 18, 2021, the Board approved the amended and restated Investment Advisory Agreement. Unless earlier terminated, the Investment Advisory Agreement will renew automatically for successive annual periods, provided that such continuance is specifically approved at least annually by the vote of the Board and by the vote of a majority of the Independent Trustees. The Investment Advisory Agreement was most recently renewed and approved by the Board, including majority of the Independent Trustees, on May 1, 2024 for a one-year period ending on May 31, 2025.

The Adviser implemented a waiver effective from the consummation of the IPO to extend the Company’s pre-IPO fee structure for a period of two years. With the waiver in place, instead of having the base management fee and each incentive fee increase to 1.00% and 17.5%, respectively, following the IPO, each such fee remained at 0.75% and 15.0% for a period of two years following the IPO (the “Waiver Period”). As a result of the fee waiver, the pre-listing management fee and incentive fee rates paid by the Company to the Adviser did not increase during the Waiver Period. Amounts waived by the Adviser are not subject to recoupment by the Adviser. The Waiver Period ended on October 28, 2023.

Base Management Fees

Starting from the consummation of the IPO, the management fee pursuant to the Investment Advisory Agreement is payable quarterly in arrears at an annual rate of 1.0% of the average value of the Company’s “gross assets” at the end of the two most recently completed calendar quarters. For purposes of the Investment Advisory Agreement, “gross assets” means the Company’s total assets determined on a consolidated basis in accordance with GAAP, excluding undrawn commitments but including assets purchased with borrowed amounts. The management fee was calculated for the quarter ended December 31, 2021, and the quarter ended December 31, 2023, at a weighted rate calculated based on the fee rates applicable before and after the consummation of the IPO and the expiration of the Waiver Period based on the number of days in the calendar quarter before and after the consummation of the IPO and the expiration of the Waiver Period.

Prior to the consummation of the IPO, the management fee was 0.75% of the average value of the Company’s gross assets at the end of the two most recently completed calendar quarters. In order to maintain the same management fee arrangement that the Company had in place prior to the IPO for a period of time following the consummation of the IPO, the Adviser voluntarily waived its right to receive the base management fee in excess of 0.75% of the average value of the Company’s gross assets at the end of the two most recently completed calendar quarters during the Waiver Period. Amounts waived by the Adviser are not subject to recoupment by the Adviser.

For the three months ended March 31, 2024 and 2023, base management fees were $26.0 million and $24.7 million, respectively, of which $0.0 million and $6.2 million, respectively, were waived. The Waiver Period ended on October 28, 2023.

As of March 31, 2024 and December 31, 2023, $26.0 million and $23.0 million, respectively, was payable to the Adviser relating to management fees.

Incentive Fees

The incentive fees consist of two components that are determined independently of each other, with the result that one component may be payable even if the other is not. One component is based on income and the other component is based on capital gains, each as described below:

(in thousands, except share amounts, per share data, percentages and as otherwise noted)

(i) Income based incentive fees:

The first part of the incentive fee, an income based incentive fee, is calculated and payable quarterly in arrears based on the Company’s Pre-Incentive Fee Net Investment Income Returns as defined in the Investment Advisory Agreement. 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 the Company’s net assets at the end of the immediately preceding quarter 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 the Company receives from portfolio companies) accrued during the calendar quarter, minus the Company’s 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. Pre-Incentive Fee Net Investment Income Returns includes, 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 the Company has not yet received in cash. Pre-incentive fee net investment income excludes any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. The Company excludes the impact of expense support payments and recoupments from pre-incentive fee net investment income. Shareholders may be charged a fee on an income amount that is higher than the income they may ultimately receive.

Pre-Incentive Fee Net Investment Income Returns, expressed as a rate of return on the value of our net assets at the end of the immediately preceding quarter, is compared to a “hurdle rate” of return of 1.5% per quarter (6.0% annualized).

Pursuant to the Investment Advisory Agreement, the Company is required to pay an income based incentive fee of 17.5% (15% prior to the consummation of the IPO), with a 1.5% hurdle and 100% catch-up. However, the Adviser implemented a voluntary waiver with respect to the income based incentive fee during the Waiver Period. The Adviser voluntarily waived its right to receive an income based incentive fee above 15% during the Waiver Period and amounts waived by the Adviser were not subject to recoupment by the Adviser.

The Company pays the Adviser an income based incentive fee based on its aggregate pre-incentive fee net investment income, as adjusted as described above, from the calendar quarter then ending and the eleven preceding calendar quarters (such period, the “Trailing Twelve Quarters”).

The hurdle amount for the income based incentive fee is determined on a quarterly basis and is equal to 1.5% multiplied by the Company’s NAV at the beginning of each applicable calendar quarter comprising the relevant Trailing Twelve Quarters. The hurdle amount is calculated after making appropriate adjustments for issuances by the Company of Common Shares, including issuances pursuant to its dividend reinvestment plan (“DRIP”) and distributions that occurred during the relevant Trailing Twelve Quarters. The income based incentive fee for any partial period will be appropriately prorated.

For the income based incentive fee, the Company will pay the Adviser a quarterly incentive fee based on the amount by which (A) aggregate pre-incentive fee net investment income in respect of the relevant Trailing Twelve Quarters exceeds (B) the hurdle amount for such Trailing Twelve Quarters. The amount of the excess of (A) over (B) described in this paragraph for such Trailing Twelve Quarters is referred to as the “Excess Income Amount”.

The income based incentive fee for each quarter will be determined as follows:

•No income based incentive fee is payable to the Adviser for any calendar quarter for which there is no Excess Income Amount.

•The Adviser will be paid 100% of the pre-incentive fee net investment income in respect of the Trailing Twelve Quarters, if any, that exceeds the hurdle amount for such Trailing Twelve Quarters, but is less than or equal to an amount, which we refer to as the “Catch-up Amount,” determined as the sum of 1.82% (7.27% annualized) (1.76% (7.06% annualized) during the Waiver Period), multiplied by the Company’s NAV at the beginning of each applicable calendar quarter comprising the relevant Trailing Twelve Quarters that is included in the calculation of the incentive fee based on income.

(in thousands, except share amounts, per share data, percentages and as otherwise noted)

•The Adviser will be paid 17.5% (15% during the Waiver Period), of the pre-incentive fee net investment income in respect of the Trailing Twelve Quarters that exceeds the Catch-up Amount.

The amount of the income based incentive fee that will be paid to the Adviser for a particular quarter will equal the excess of (a) the income based incentive fee so calculated over (b) the aggregate income based incentive fee that was paid in respect of the first eleven calendar quarters included in the relevant Trailing Twelve Quarters subject to the Incentive Fee Cap as described below.

The income based incentive fee that will be paid to the Adviser for a particular quarter is subject to a cap (the “Incentive Fee Cap”). The Incentive Fee Cap for any quarter is an amount equal to (a) 17.5% (15% prior to the end of the Waiver Period), of the Cumulative Net Return (as defined below) during the relevant Trailing Twelve Quarters minus (b) the aggregate income based incentive fee that was paid in respect of the first eleven calendar quarters (or the portion thereof) included in the relevant Trailing Twelve Quarters.

“Cumulative Net Return” means (x) the pre-incentive fee net investment income in respect of the relevant Trailing Twelve Quarters minus (y) any Net Capital Loss (as defined below), if any, in respect of the relevant Trailing Twelve Quarters. If, in any quarter, the Incentive Fee Cap is zero or a negative value, the Company will pay no income based incentive fee to the Adviser for such quarter. If, in any quarter, the Incentive Fee Cap for such quarter is a positive value but is less than the income based incentive fee that is payable to the Adviser for such quarter (before giving effect to the Incentive Fee Cap) calculated as described above, the Company will pay an income based incentive fee to the Adviser equal to the Incentive Fee Cap for such quarter. If, in any quarter, the Incentive Fee Cap for such quarter is equal to or greater than the income based incentive fee that is payable to the Adviser for such quarter (before giving effect to the Incentive Fee Cap) calculated as described above, the Company will pay an income based incentive fee to the Adviser equal to the incentive fee calculated as described above for such quarter without regard to the Incentive Fee Cap.

“Net Capital Loss” in respect of a particular period means the difference, if positive, between (i) aggregate capital losses, whether realized or unrealized, in such period and (ii) aggregate capital gains, whether realized or unrealized, in such period.

These calculations are prorated for any period of less than three months and adjusted for any share issuances or repurchases during the relevant quarter. As the consummation of the IPO occurred on a date other than the first day of a calendar quarter, the income based incentive fee with respect to the Company’s pre-incentive fee net investment income was calculated for such calendar quarter at a weighted rate calculated based on the fee rates applicable before and after the consummation of the IPO based on the number of days in such calendar quarter before and after the consummation of the IPO. In no event will the amendments to the income based incentive fee include the incentive fee cap and allow the Adviser to receive greater cumulative income based incentive fees under the Investment Advisory Agreement than it would have under the prior investment advisory agreement. Amounts waived by the Adviser are not subject to recoupment by the Adviser.

(ii) Capital gains based incentive fee:

Starting from the completion of the IPO, the second part of the incentive fee, a capital gains incentive fee, is determined and payable in arrears as of the end of each calendar year in an amount equal to 17.5% of realized capital gains, if any, on a cumulative basis 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 fees as calculated in accordance with GAAP.

Prior to the IPO, the second part of the incentive fee, a capital gains incentive fee, was determined and payable in arrears as of the end of each calendar year in an amount equal to 15.0% of realized capital gains, if any, on a cumulative basis 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 fees as calculated in accordance with GAAP. However, similar to the voluntary waivers referenced above, the Adviser voluntarily waived its right to receive a capital gains based incentive fee above 15% from the date of consummation of the IPO through the Waiver Period. The Company will accrue, but will not pay, a capital gains incentive fee with respect to unrealized appreciation because a capital gains incentive fee would be owed to the Adviser if the Company were to sell the relevant investment and realize a capital gain. Amounts waived by the Adviser are not subject to recoupment by the Adviser.

For the three months ended March 31, 2024 and 2023, the Company accrued income based incentive fees of $35.8 million and $30.4 million, respectively, of which $0.0 million and $4.3 million, respectively, were waived. The Waiver Period ended on October 28, 2023.

As of March 31, 2024 and December 31, 2023, $35.8 million and $34.4 million, respectively, was payable to the Adviser for income based incentive fees.

For the three months ended March 31, 2024, the Company accrued capital gains incentive fees of $3.1 million. For the three months ended March 31, 2023, the Company reversed previously accrued capital gains incentive fee of $(1.6) million.

Administration Agreement

On October 1, 2018, the Company entered into an Administration Agreement with the Administrator. Under the terms of the Administration Agreement, the Administrator provides, or oversees the performance of, administrative and compliance services, including, but not limited to, maintaining financial records, overseeing the calculation of NAV, compliance monitoring (including diligence and oversight of the Company’s other service providers), preparing reports to shareholders and reports filed with the United States Securities and Exchange Commission (“SEC”), preparing materials and coordinating meetings of the Company’s Board, managing the payment of expenses and the performance of administrative and professional services rendered by others and providing office space, equipment and office services. The Administrator may also offer to provide, on the Company’s behalf, managerial assistance to the Company’s portfolio companies. The initial term of the agreement was two years from October 1, 2018. Unless earlier terminated, the Administration Agreement will renew automatically for successive annual periods, provided that such continuance is approved at least annually by (i) the vote of the Board or by a majority vote of the outstanding voting securities of the Company and (ii) the vote of a majority of the Independent Trustees. The Administration Agreement was most recently renewed and approved by the Board, including a majority of the Independent Trustees, on May 1, 2024, for a one-year period.

For providing these services, the Company will reimburse the Administrator for its costs, expenses and allocable portion of overhead (including rent, office equipment and utilities) and other expenses incurred by the Administrator in performing its administrative obligations under the Administration Agreement, including but not limited to: (i) the Company’s chief compliance officer, chief financial officer and their respective staffs; (ii) investor relations, legal, operations and other non-investment professionals (including information technology professionals) at the Administrator that perform duties for the Company; and (iii) any internal audit group personnel of Blackstone or any of its affiliates. The Administrator has elected to forgo any reimbursement for rent and other occupancy costs for the three months ended March 31, 2024 and 2023.

For the three months ended March 31, 2024 and 2023, the Company incurred $0.7 million and $0.4 million, respectively, in expenses under the Administration Agreement, which were recorded in Administrative service expenses in the Company’s Condensed Consolidated Statements of Operations.

As of March 31, 2024 and December 31, 2023, $0.6 million and $1.1 million, respectively, was unpaid and included in Due to affiliates in the Condensed Consolidated Statements of Assets and Liabilities.

Sub-Administration and Custody Agreement

On October 1, 2018, the Administrator entered into a sub-administration agreement (the “Sub-Administration Agreement”) with State Street Bank and Trust Company (the “Sub-Administrator”) under which the Sub-Administrator provides various accounting and administrative services to the Company. The Sub-Administrator also serves as the Company’s custodian (the “Custodian”). The initial term of the Sub-Administration Agreement is two years from the effective date and after expiration of the initial term and the Sub-Administration Agreement shall automatically renew for successive one-year periods, unless a written notice of non-renewal is delivered prior to 120 days prior to the expiration of the initial term or renewal term.

Expense Support and Conditional Reimbursement Agreement

On December 12, 2018, the Company entered into an Expense Support and Conditional Reimbursement Agreement (the “Expense Support Agreement”) with the Adviser pursuant to which the Adviser was able to elect to pay certain expenses of the Company on the Company’s behalf (each, an “Expense Payment”), provided that no portion of the payment was used to pay any interest of the Company. Any Expense Payment that the Adviser committed to pay was to be paid by the 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 Adviser or its affiliates.

Pursuant to the Expense Support Agreement, following any calendar quarter in which Available Operating Funds (as defined below) exceeded the cumulative distributions accrued to the Company’s shareholders based on distributions declared with respect to record dates occurring in such calendar quarter (the “Excess Operating Funds”), the Company was required to pay such Excess Operating Funds, or a portion thereof, to the Adviser until such time as all Expense Payments made by the Adviser to the Company within three years prior to the last business day of such calendar quarter were reimbursed. Any payments required to be made by the Company to the Adviser are referred to herein as a “Reimbursement Payment”. Available Operating Funds means the sum of (i) the Company’s net investment company taxable income (including net short-term capital gains reduced by net long-term capital losses), (ii) the Company’s 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 Expense Support Agreement terminated by its own terms on October 28, 2021. The Company’s obligation to make Reimbursement Payments survived the termination of the Expense Support Agreement and may be made for a period of up to three years, in accordance with the terms of the Expense Support Agreement. The Company’s obligation to make a Reimbursement Payment becomes a liability of the Company on the last business day of the applicable calendar quarter. As of March 31, 2024 and 2023, there are no amounts subject to the Reimbursement Payment obligation.

As of March 31, 2024 and 2023, there was no unreimbursed Expense Payments. For the three months ended March 31, 2024 and 2023, the Adviser made no Expense Payments and the Company made no Reimbursement Payments related to Expense Payments by the Adviser.

(1)Weighted averages are calculated based on fair value of investments.

The significant unobservable input used in the yield analysis is the discount rate based on comparable market yields. The significant unobservable input used for market quotations are broker quoted prices provided by independent pricing services. The significant unobservable input used under the market approach is the Performance Multiple. Significant increases in discount rates would result in a significantly lower fair value measurement. Significant decreases in quoted prices or Performance Multiples would result in a significantly lower fair value measurement.

Note 7. Commitments and Contingencies

Portfolio Company Commitments

The Company’s investment portfolio may contain debt investments which are in the form of lines of credit or delayed draw commitments, which require us to provide funding when requested by portfolio companies in accordance with underlying loan agreements. As of March 31, 2024 and December 31, 2023, the Company had unfunded commitments, including delayed draw term loans and revolvers, with an aggregate amount of $1,421.3 million and $985.9 million, respectively.

Additionally, from time to time, the Adviser and its affiliates may commit to an investment on behalf of the investment vehicles it manages, including the Company. Certain terms of these investments are not finalized at the time of the commitment and each respective investment vehicle’s allocation may change prior to the date of funding. In this regard, as of March 31, 2024 and December 31, 2023, the Company estimates that $373.6 million and $221.3 million, respectively, of investments that are committed but not yet funded.

Other Commitments and Contingencies

From time to time, the Company may become a party to certain legal proceedings incidental to the normal course of its business. At March 31, 2024 and December 31, 2023, management is not aware of any material pending legal proceedings.

Note 8. Net Assets

Shares Issued

The Company has the authority to issue an unlimited number of Common Shares at $0.001 per share par value.

On October 28, 2021, the Company priced its IPO, issuing 9,180,000 of its Common Shares at a public offering price of $26.15 per share. Net of underwriting fees, the Company received cash proceeds, before offering expenses, of $230.6 million. On November 4, 2021, the underwriters exercised their option to purchase an additional 1,377,000 shares of Common Shares, which resulted in cash proceeds, before offering expenses, of $33.8 million. The Company’s Common Shares began trading on the NYSE under the symbol “BXSL” on October 28, 2021. In connection with the listing of the Company’s Common Shares on the NYSE, the Board decided to eliminate any outstanding fractional Common Shares (the “Fractional Shares”), as permitted by Delaware law by rounding down the number of Fractional Shares held by each of our shareholders to the nearest whole share and paying each shareholder cash for such Fractional Shares.

On August 14, 2023, the Company completed a follow-on offering under its shelf registration statement, issuing 6,500,000 of its Common Shares at a price to the underwriters of $26.78 per share. Net of underwriting fees, the Company received cash proceeds, before offering expenses, of $174.1 million. On August 18, 2023, the underwriters exercised, in full, their option to purchase an additional 975,000 shares of Common Shares, which resulted in cash proceeds, before offering expenses, of $26.1 million. The Company incurred offering expenses of $0.4 million in connection with the follow-on offering.

As of March 31, 2024, the Company is party to six separate equity distribution agreements with sales agents (“Equity Distribution Agreements”), pursuant to which the Company may sell, from time to time, up to an aggregate sales price of $500.0 million of its Common Shares. Sales of Common Shares made pursuant to the Equity Distribution Agreements may be made in negotiated transactions or transactions that are deemed to be “at-the-market” offerings as defined in Rule 415(a)(5) under the Securities Act of 1933, as amended. Actual sales depend on a variety of factors including market conditions, the trading price of the Company’s Common Shares, the Company’s capital needs, and the Company’s determination of the appropriate sources of funding to meet such needs. As of March 31, 2024, Common Shares with an aggregate sales price of $500.0 million remained available for issuance under the Equity Distribution Agreements.

Date Declared	Record Date	Payment Date	Per Share Amount		Total Amount
February 28, 2024	March 31, 2024	April 26, 2024	$	0.7700	$	147,743
Total distributions			$	0.7700	$	147,743

The following table summarizes the Company’s distributions declared and payable for the three months ended March 31, 2023 (dollars in thousands except per share amounts):

Date Declared	Record Date	Payment Date	Per Share Amount		Total Amount
February 27, 2023	March 31, 2023	April 27, 2023	$	0.7000	$	112,400
Total distributions			$	0.7000	$	112,400

Dividend Reinvestment

The Company has adopted the DRIP, pursuant to which it reinvests all cash dividends declared by the Board on behalf of its shareholders who do not elect to receive their dividends in cash. As a result, if the Board and the Company declares, a cash dividend or other distribution, then the Company’s shareholders who have not opted out of its dividend reinvestment plan will have their cash distributions automatically reinvested in additional shares as described below, rather than receiving the cash dividend or other distribution. Starting from the consummation of the IPO, the number of shares to be issued to a shareholder is determined by dividing the total dollar amount of the cash dividend or distribution payable to a shareholder by the market price per common share at the close of regular trading on the NYSE on the payment date of a distribution, or if no sale is reported for such day, the average of the reported bid and ask prices. However, if the market price per share on the payment date of a cash dividend or distribution exceeds the most recently computed NAV per share, the Company will issue shares at the greater of (i) the most recently computed NAV per share and (ii) 95% of the current market price per share (or such lesser discount to the current market price per share that still exceeded the most recently computed NAV per share). For example, if the most recently computed NAV per share is $25.00 and the market price on the payment date of a cash dividend is $24.00 per share, the Company will issue shares at $24.00 per share. If the most recently computed NAV per share is $25.00 and the market price on the payment date of a cash dividend is $27.00 per share, the Company will issue shares at $25.65 per share (95% of the current market price). If the most recently computed NAV per share is $25.00 and the market price on the payment date of a cash dividend is $26.00 per share, the Company will issue shares at $25.00 per share.

Shareholders who receive distributions in the form of shares will generally be subject to the same U.S. federal, state and local tax consequences as if they received cash distributions; however, since their cash distributions will be reinvested, those shareholders will not receive cash with which to pay any applicable taxes. The Company intends to use newly issued shares to implement the plan.

Financial Statements” hereto and “Part II, Item 8-Consolidated Financial Statement and Supplementary Data” of our Annual Report on Form 10-K for the year ended December 31, 2023, as updated from time to time by the Company's periodic filings with the SEC. This discussion contains forward-looking statements and involves numerous risks, uncertainties, and other factors outside of the Company's control including, but not limited to, those set forth in “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2023, as updated from time to time by the Company's periodic filings with the SEC.

Overview and Investment Framework

We are a Delaware statutory trust structured as a non-diversified, closed-end management investment company that has elected to be regulated as a BDC under the 1940 Act. In addition, for U.S. federal income tax purposes, we elected to be treated as a RIC under the Code. We are managed by our Adviser. The Administrator will provide the administrative services necessary for us to operate.

Our investment objectives are to generate current income and, to a lesser extent, long-term capital appreciation.

Under normal market conditions, we generally invest at least 80% of our total assets (net assets plus borrowings for investment purposes) in secured debt investments and our portfolio is composed primarily of first lien senior secured and unitranche loans. To a lesser extent, we have and may continue to also invest in second lien, third lien, unsecured or subordinated loans and other debt and equity securities. In limited instances we may retain the “last out” portion of a first-lien loan. In such cases, the “first out” portion of the first lien loan would receive priority with respect to payment over our “last out” position. In exchange for the higher risk of loss associated with such “last out” portion, we would earn a higher rate of interest than the “first out” position. We do not currently focus on investments in issuers that are distressed or in need of rescue financing.

Key Components of Our Results of Operations

Investments

We focus primarily on loans and securities, including syndicated loans, of private U.S. companies, which includes larger and middle market companies. In many market environments, we believe such a focus offers an opportunity for superior risk-adjusted returns.

Our level of investment activity (both the number of investments and the size of each investment) can and will vary substantially from period to period depending on many factors, including the amount of debt and equity capital available to middle market companies, the level of merger and acquisition activity for such companies, the general economic environment, trading prices of loans and other securities and the competitive environment for the types of investments we make.

Revenues

We generate revenues in the form of interest income from the debt securities we hold and dividends. Our debt investments typically have a term of five to eight years and bear interest at floating rates on the basis of a benchmark such as SOFR, SONIA, etc. In some instances, we receive payments on our debt investments based on scheduled amortization of the outstanding balances. In addition, we may 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 may 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 from various fees in the ordinary course of business such as in the form of commitment, loan origination, structuring, consent, waiver, amendment, syndication and other miscellaneous fees as well as fees for providing managerial assistance to our portfolio companies.

Expenses

Except as specifically provided below, all investment professionals and staff of the Adviser, when and to the extent engaged in providing investment advisory services to us, and the base compensation, bonus and benefits, and the routine overhead expenses, of such personnel allocable to such services, will be provided and paid for by the Adviser. We bear all other costs and expenses of our operations, administration and transactions, including, but not limited to (a) investment advisory fees, including management fees and incentive fees, to the Adviser, pursuant to the Investment Advisory Agreement; (b) our allocable portion of compensation, overhead (including rent, office equipment and utilities) and other expenses incurred by the Administrator in performing its administrative obligations under the Administration Agreement, including but not limited to: (i) our chief compliance officer, chief financial officer and their respective staffs; (ii) investor relations, legal, operations and other non-investment professionals (including information technology professionals) at the Administrator that perform duties for us; and (iii) any internal audit group personnel of Blackstone or any of its affiliates; and (c) all other expenses of our operations, administrations and transactions.

From time to time, the Adviser, the Administrator or their affiliates may pay third-party providers of goods or services on our behalf. We will reimburse the Adviser, Administrator or such affiliates thereof for any such amounts. From time to time, the Adviser or the Administrator may defer or waive fees and/or rights to be reimbursed for expenses. The Administrator has elected to forgo any reimbursement for rent and other occupancy costs for the three months ended March 31, 2024 and 2023. However, the Administrator may seek reimbursement for such costs in future periods. All of the foregoing expenses will ultimately be borne by our shareholders.

Costs and expenses of the Administrator and the Adviser that are eligible for reimbursement by us will be reasonably allocated on the basis of time spent, assets under management, usage rates, proportionate holdings, a combination thereof or other reasonable methods determined by the Administrator in accordance with policies adopted by the Board.

(1)Computed as (a) the annual stated interest rate or yield plus the annual accretion of discounts or less the annual amortization of premiums, as applicable, on accruing debt included in such securities, divided by (b) total debt investments (at fair value or cost, as applicable) included in such securities. Actual yields earned over the life of each investment could differ materially from the yields presented above.

(2)As of March 31, 2024 and December 31, 2023, the weighted average total portfolio yield at cost was 11.6% and 11.8%, respectively. The weighted average total portfolio yield at fair value was 11.7% and 11.8%, respectively.

(3)Includes all private debt investments for which fair value is determined by our Board in conjunction with a third-party valuation firm and excludes quoted assets. Average loan-to-value represents the net ratio of loan-to-value for each portfolio company, weighted based on the fair value of total applicable private debt investments. Loan-to-value is calculated as the current total net debt through each respective loan tranche divided by the estimated enterprise value of the portfolio company as of the most recent quarter end.

(4)Amount rounds to less than 0.1% for December 31, 2023.

(5)As a percentage of total amortized cost of Investments. Assets on non-accrual represented less than 0.1% and less than 0.1% of total fair value of Investments as of March 31, 2024 and December 31, 2023, respectively.

(6)As a percentage of total fair value of debt investments. As of March 31, 2024 and December 31, 2023, debt investments bearing a floating rate represented 98.8% and 98.9% , respectively, of total Investment at fair value.

As of March 31, 2024, our portfolio companies had a weighted average annual revenue of $768.0 million and weighted average annual EBITDA of $193.1 million. These calculations include all private debt investments for which fair value is determined by the Board of Trustees in conjunction with a third-party valuation firm and excludes quoted assets. Amounts are weighted based on fair market value of each respective investment. Amounts were derived from the most recently available portfolio company financial statements, have not been independently verified by us, and may reflect a normalized or adjusted amount. Accordingly, we make no representation or warranty in respect of this information.

Results of Operations

The following table represents the operating results (dollar amounts in thousands):

	Three Months Ended March 31,
	2024		2023
Total investment income	$	303,959	$	264,938
Net expenses before excise tax	134,763		113,141
Net investment income before excise tax	169,196		151,797
Excise tax expense	3,350		2,622
Net investment income after excise tax	165,846		149,175
Net change in unrealized appreciation (depreciation)	11,766		(14,544)
Net realized gain (loss)	6,143		4,167
Net increase (decrease) in net assets resulting from operations	$	183,755	$	138,798

Net increase (decrease) in net assets resulting from operations can vary from period to period as a result of various factors, including acquisitions, the level of new investment commitments, the recognition of realized gains and losses and changes in unrealized appreciation and depreciation on the investment portfolio. As a result, comparisons may not be meaningful.

Investment Income

Investment income was as follows (dollar amounts in thousands):

	Three Months Ended March 31,
	2024		2023
Interest income	$	283,264	$	254,221
Payment in-kind interest income	20,462		9,841
Fee income	233		876
Total investment income	$	303,959	$	264,938

81

Table of Contents

Total investment income increased to $304.0 million for the three months ended March 31, 2024, an increase of $39.0 million, or 15%, compared to the same period in the prior year primarily attributable to increased reference interest rates driving increased interest income from our investments.

Additionally, for the three months ended March 31, 2024, we recorded $1.9 million of non-recurring interest income (e.g., prepayment premiums, accelerated accretion of upfront loan origination fees and unamortized discounts, etc.) as compared to $0.4 million in the prior year primarily a result of increased prepayments.

For the three months ended March 31, 2024 and 2023, Payment-in-kind interest income represented 6.7% and 3.7% of investment income, respectively.

We expect that investment income will vary based on a variety of factors including the pace of our originations, repayments and changes in interest rates.

While elevated interest rates have favorably impacted our investment income during the three months ended March 31, 2024, further interest rate increases and the resulting higher cost of capital have the potential to negatively impact the free cash flow and credit quality of certain borrowers which could impact their ability to make principal and interest payments. If such interest rate increases occur concurrently with a period of economic weakness or a slowdown in growth, our borrowers’ and/or our portfolio performance may be negatively impacted. Further, significant market dislocation as a result of changing economic conditions could limit the liquidity of certain assets traded in the credit markets, and this could impact our ability to sell such assets at attractive prices or in a timely manner.

Interest Expense

Total interest expense (including unused fees and other debt financing expenses), was $66.7 million for the three months ended March 31, 2024, remaining consistent with the same period in the prior year. This was primarily driven by an increase in our weighted average interest rate on our borrowings relative to the prior period offset by a decrease in our average principal of debt outstanding.

82

Table of Contents

Our weighted average interest rate (including unused fees, accretion of net discounts on unsecured debt, and excluding amortization of deferred financing costs) increased to 5.10% for the three months ended March 31, 2024 from 4.68% for the same period in the prior year. The average principal of debt outstanding decreased to $5,046.2 million for the three months ended March 31, 2024 from $5,619.0 million for the same period in the prior year.

Management Fees

Management fees increased to $26.0 million for the three months ended March 31, 2024, an increase of $1.3 million, or 5%, compared to the same period in the prior year, due to an increase in average quarter end gross assets. For the three months ended March 31, 2024, our average quarter end gross assets increased to $10,419.8 million at March 31, 2024 from $9,878.5 million at March 31, 2023.

The Adviser voluntarily waived management fees following the IPO such that the management fee remained at 0.75% for a period of two years following the IPO (versus the contractual rate of 1.00%), which resulted in a waiver of $6.2 million for the three months ended March 31, 2023. The Waiver Period ended on October 28, 2023.

Income Based Incentive Fees

Income based incentive fees increased to $35.8 million for the three months ended March 31, 2024 from $30.4 million for the same period in the prior year primarily due to an increase in pre-incentive fee net investment income. Pre-incentive fee net investment income increased to $204.8 million for the three months ended March 31, 2024 from $173.7 million for the same period in the prior year.

The Adviser voluntarily waived incentive fees following the IPO such that the fee remained at 15.0% for a period of two years following the IPO (versus the contractual rate of 17.5%), which resulted in a waiver of $4.3 million for the three months ended March 31, 2023. The Waiver Period ended on October 28, 2023.

Capital Gains Incentive Fees

We accrued capital gains incentive fees of $3.1 million for the three months ended March 31, 2024, as compared to the reversal of the previously accrued capital gains incentive fees of $(1.6) million for the three months ended March 31, 2023 primarily due to net unrealized gains for the three months ended March 31, 2024 compared to unrealized losses during the same period in the prior year.

The accrual for any capital gains incentive fee under GAAP in a given period may result in an additional expense if such cumulative amount is greater than in the prior period or a reduction of previously recorded expense if such cumulative amount is less in the prior period. If such cumulative amount is negative, then there is no accrual.

Other Expenses

Professional fees include legal, rating agencies, audit, tax, valuation, technology and other professional fees incurred related to the management of us. Administrative service fees represent fees paid to the Administrator for our allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations under the Administration Agreement, including our allocable portion of the cost of certain of our executive officers, their respective staff and other non-investment professionals that perform duties for us. Other general and administrative expenses include insurance, filing, research, our sub-administrator, subscriptions and other costs.

Total other expenses decreased to $3.0 million for the three months ended March 31, 2024 from $3.4 million for the same period in the prior year primarily due to a decrease in Other General and Administrative expenses.

Income Taxes, Including Excise Taxes

We elected to be treated as a RIC under Subchapter M of the Code, and we intend to operate in a manner so as to continue to qualify for the tax treatment applicable to RICs. To qualify for taxation as a RIC, we must, among other things, distribute to our shareholders in each taxable year generally at least 90% of the sum of our investment company taxable income, as defined by the Code (without regard to the deduction for dividends paid), and net tax-exempt income for that taxable year. To maintain our tax treatment as a RIC, we, among other things, intend to make the requisite distributions to our shareholders, which generally relieve us from corporate-level U.S. federal income taxes.

83

Table of Contents

Depending on the level of taxable income earned in a tax year, we may carry forward taxable income (including net capital gains, if any) in excess of current year dividend distributions from the current tax year into the next tax year and pay a nondeductible 4% U.S. federal excise tax on such taxable income, as required. To the extent that we determine that our estimated current year annual taxable income will be in excess of estimated current year dividend distributions from such income, we will accrue excise tax on estimated excess taxable income.

For the three months ended March 31, 2024 and 2023, we accrued $3.4 million and $2.6 million, respectively, of U.S. federal excise tax.

Net Unrealized Gain (Loss)

Net change in unrealized gain (loss) was comprised of the following (dollar amounts in thousands):

	Three Months Ended March 31,
	2024		2023
Net change in unrealized gain (loss) on investments	$	11,787	$	(11,403)
Net change in unrealized gain (loss) on translation of assets and liabilities in foreign currencies	(21)		(3,141)
Net change in unrealized gain (loss)	$	11,766	$	(14,544)

For the three months ended March 31, 2024, the net change in unrealized gains of $11.8 million was primarily driven by the increase in the fair value of our debt investments. The fair value of our debt investments as a percentage of principal increased by 0.3%, during the three months ended March 31, 2024 driven primarily by the improving economic outlook.

Net Realized Gain (Loss)

The realized gains and losses on fully exited and partially exited investments comprised of the following (dollar amounts in thousands):

	Three Months Ended March 31,
	2024		2023
Net realized gain (loss) on investments	$	428	$	(3,486)
Net realized gain (loss) on foreign currency transactions	5,715		7,653
Net realized gain (loss)	$	6,143	$	4,167

For the three months ended March 31, 2024, we generated realized gains on investments of $0.4 million, primarily from full or partial sales or restructures of our debt investments.

Net realized gains of $5.7 million were generated on foreign currency transactions during the three months ended March 31, 2024, primarily as a result of fluctuations in the GBP exchange rate vs. USD.

Financial Condition, Liquidity and Capital Resources

Our liquidity and capital resources are generated primarily from cash flows from interest, dividends and fees earned from our investments and principal repayments, our credit facilities, debt securitization transactions, and other secured and unsecured debt. We may also generate cash flow from operations, future borrowings and future offerings of securities including public and/or private issuances of debt and/or equity securities through both registered offerings and private offerings. The primary uses of our cash and cash equivalents are for (i) originating loans and purchasing senior secured debt investments, (ii) funding the costs of our operations (including fees paid to our Adviser and expense reimbursements paid to our Administrator), (iii) debt service, repayment and other financing costs of our borrowings and (iv) cash distributions to the holders of our shares.

84

Table of Contents

To facilitate public issuances of debt and/or equity securities, in July 2022, we filed a shelf registration statement with the SEC that is effective for a term of three years and expires in July 2025. The amount of securities to be issued pursuant to the shelf registration statement filed in July 2022 was not specified when it was filed and there is no specific dollar limit on the amount of securities we may issue. The securities covered by the registration statement filed in July 2022 include: (i) Common Shares; (ii) preferred shares; (iii) debt securities; (iv) subscription rights; and (v) warrants. The specifics of any future offerings, along with the use of proceeds of any securities offered, will be described in detail in a prospectus supplement, or other offering materials, at the time of any offering.

As of March 31, 2024 and December 31, 2023, our debt consisted of asset based leverage facilities, a revolving credit facility, and unsecured note issuances. We may from time to time enter into additional credit facilities, increase the size of our existing credit facilities or issue further debt securities. Any such incurrence or issuance would be subject to prevailing market conditions, our liquidity requirements, contractual and regulatory restrictions and other factors. In accordance with the 1940 Act, with certain limited exceptions, we are only allowed to incur borrowings, issue debt securities or issue preferred stock, if immediately after the borrowing or issuance, the ratio of total assets (less total liabilities other than indebtedness) to total indebtedness plus preferred stock, is at least 150%. As of March 31, 2024 and December 31, 2023, we had an aggregate amount of $5,298.0 million and $4,937.9 million of senior securities outstanding, respectively, and our asset coverage ratio was 197.3% and 200.3%, respectively. We seek to carefully consider our unfunded commitments for the purpose of planning our ongoing financial leverage. Further, we maintain sufficient borrowing capacity within the 150% asset coverage limitation to cover any outstanding unfunded commitments we are required to fund. From time to time we may also repurchase our outstanding debt. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions, and other factors. The amounts involved in any such purchase transactions, individually or in the aggregate, may be material.

Cash and cash equivalents as of March 31, 2024, taken together with our $1,302.0 million of unused capacity under our credit facilities (subject to borrowing base availability, $1,302.0 million is available to borrow) is expected to be sufficient for our investing activities and to conduct our operations in the near term. Additionally, we held $108.8 million of Level 2 debt investments as of March 31, 2024, which could provide additional liquidity if necessary.

Although we have historically been able to obtain sufficient borrowing capacity, a deterioration in economic conditions or any other negative economic developments could restrict our access to financing in the future. We may not be able to find new financing for future investments or liquidity needs and, even if we are able to obtain such financing, such financing may not be on as favorable terms as we have previously obtained. These factors may limit our ability to make new investments and adversely impact our results of operations.

As of March 31, 2024, we had $147.7 million in cash and cash equivalents. During the three months ended March 31, 2024, cash used in operating activities was $395.5 million, primarily due to purchases of investments of $719.1 million partially offset by sales of investments and principal repayments of $186.7 million and receipt of interest payments from our investments. Cash provided by financing activities was $388.3 million during the period, which was primarily as a result of borrowings on our credit facilities and Unsecured Notes of $363.8 million and $162.0 million of proceeds from the issuance of our Common Shares partially offset by dividends paid in cash of $137.4 million.

Equity

We also access liquidity through our “at-the-market” offering program (the “ATM Program”), pursuant to which we may sell, from time to time, additional Common Shares. During the three months ended March 31, 2024, we sold Common Shares for net proceeds of $162.0 million through our ATM Program. On March 28, 2024, we filed a new prospectus supplement under which may sell up to an aggregate sales price of $500.0 million of our Common Shares as part of the ATM Program. As of March 31, 2024, $500.0 million of Common Shares were available for issuance under the ATM Program.

For additional information on our ATM Program, see “Item 1. Financial Statements—Notes to Condensed Consolidated Financial Statements—Note 8. Net Assets.”

Distributions

The following table summarizes our distributions declared and payable for the three months ended March 31, 2024 (dollar amounts in thousands, except per share amounts):

Date Declared	Record Date	Payment Date	Per Share Amount		Total Amount
February 28, 2024	March 31, 2024	April 26, 2024	$	0.7700	$	147,743
Total distributions			$	0.7700	$	147,743

With respect to distributions, we have adopted an “opt out” dividend reinvestment plan for shareholders. As a result, in the event of a declared cash distribution or other distribution, each shareholder that has not “opted out” of the dividend reinvestment plan will have their dividends or distributions automatically reinvested in additional shares rather than receiving cash distributions. Shareholders who receive distributions in the form of shares will be subject to the same U.S. federal, state and local tax consequences as if they received cash distributions.

For additional information on our distributions and dividend reinvestment plan, see “Item 1. Financial Statements—Notes to Condensed Consolidated Financial Statements—Note 8. Net Assets.”

Share Repurchase Plan

In February 2023, our Board approved a share repurchase plan, under which we were authorized to repurchase up to $250 million in the aggregate of our outstanding Common Shares in the open market at prices below our NAV per share for a one-year term, in accordance with the guidelines specified in Rule 10b-18 of the Exchange Act (the “10b-18 Plan”). The 10b-18 Plan was not renewed and terminated by its terms on February 22, 2024.

We did not repurchase any of our shares under the 10b-18 Plan for the three months ended March 31, 2024.

For additional information on our share repurchases, see “Item 1. Financial Statements—Notes to Condensed Consolidated Financial Statements—Note 8. Net Assets.”

Borrowings

As of March 31, 2024 and December 31, 2023, we had an aggregate principal amount of $5,298.0 million and $4,937.9 million, respectively, of debt outstanding.

For additional information on our debt obligations, see “Item 1. Financial Statements—Notes to Condensed Consolidated Financial Statements—Note 6. Borrowings.”

Off-Balance Sheet Arrangements

Portfolio Company Commitments

Our investment portfolio contains and is expected to continue to contain debt investments which are in the form of lines of credit or delayed draw commitments, which require us to provide funding when requested by portfolio companies in accordance with underlying loan agreements. As of March 31, 2024 and December 31, 2023, we had unfunded commitments, including delayed draw term loans and revolvers with an aggregate principal amount of $1,421.3 million and $985.9 million, respectively.

Additionally, from time to time, the Adviser and its affiliates may commit to an investment on behalf of the investment vehicles it manages, including the Company. Certain terms of these investments are not finalized at the time of the commitment and each respective investment vehicle's allocation may change prior to the date of funding. In this regard, as of March 31, 2024 and December 31, 2023, we estimate that $373.6 million and $221.3 million, respectively, of investments were committed but not yet funded.

Other Commitments and Contingencies

From time to time, we may become a party to certain legal proceedings incidental to the normal course of our business. At March 31, 2024, management is not aware of any material pending legal proceedings.

Related-Party Transactions

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

•the Investment Advisory Agreement; and

•the Administration Agreement.

In addition to the aforementioned agreements, we, our Adviser and certain of our Adviser’s affiliates have been granted exemptive relief by the SEC to co-invest with other funds managed by our Adviser or its affiliates in a manner consistent with our investment objectives, positions, policies, strategies and restrictions as well as regulatory requirements and other pertinent factors. See “Item 1. Financial Statements—Notes to Condensed Consolidated Financial Statements—Note 3. Agreements and Related Party Transactions.”

The three months ended March 31, 2024 have been characterized by continued volatility in global markets, driven by investor concerns over inflation, elevated interest rates, slowing economic growth, political and regulatory uncertainty and geopolitical conditions, including the wars in Ukraine and Russia and in the Middle East. Events affecting financial institutions during the past year also contributed to volatility in global markets and diminished liquidity and credit availability.

During 2023 and throughout the first quarter of 2024, inflation began to moderate as a result of the monetary policy tightening actions taken by central banks, including maintaining elevated interest rates. These higher interest rates have created further uncertainty for the economy and for our borrowers. Although our business model is such that rising interest rates will, all else being equal, correlate to increases in our net income, further increases in interest rates may adversely affect our existing borrowers and lead to nonperformance, as higher costs may dampen consumer spending and slow corporate profit growth, which may negatively impact our portfolio companies as they may be susceptible to economic downturns or recessions and may be unable to repay our loans during these periods. Therefore, during these periods our non-performing assets may increase and the value of our portfolio may decrease if we are required to write down the values of our investments. Adverse economic conditions may also decrease the value of collateral securing some of our loans and the value of our equity investments. It remains difficult to predict the full impact of recent changes and any future changes with respect to interest rates or inflation.

Additionally, bank closures in the United States over the course of 2023 have caused uncertainty for financial services companies and fear of instability in the global financial system generally, which may also have other implications for broader economic and monetary policy, including interest rate policy. There can be no assurances that conditions in the banking sector and in global financial markets will not worsen and/or adversely affect the Company, its portfolio companies or their respective financial performance.

Critical Accounting Estimates

The preparation of the condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Changes in the economic environment, financial markets, and any other parameters used in determining such estimates could cause actual results to differ.

Our critical accounting policies and estimates, including those relating to the valuation of our investment portfolio, are described in our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on February 28, 2024, and elsewhere in our filings with the SEC. There have been no material changes in our critical accounting policies and practices.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Uncertainty with respect to the economic conditions has introduced significant volatility in the financial markets, and the effect of the volatility could materially impact our market risks. We are subject to financial market risks, including valuation risk and interest rate risk. Our exposure to market risk has not materially changed from what was previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Item 4. Controls and Procedures.

(a) Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) that are designed to ensure that information required to be disclosed in the Company’s reports under the Exchange Act is recorded, processed, and summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its Co-Chief Executive Officers and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. An evaluation of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q was made under the supervision and with the participation of our management, including our Co-Chief Executive Officers and Chief Financial Officer.

Based upon this evaluation, our Co-Chief Executive Officers and Chief Financial Officer have concluded that our disclosure controls and procedures are (a) effective to ensure that information required to be disclosed by us in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by SEC rules and forms and (b) include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in reports filed or submitted under the Exchange Act is accumulated and communicated to our management, including our Co-Chief Executive Officers and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

(b) Changes in Internal Controls Over Financial Reporting

There have been no changes in our internal control over financial reporting that occurred during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings.

We are not currently subject to any material legal proceedings. From time to time, we may be a party to certain legal proceedings in the ordinary course of business, including proceedings relating to the enforcement of our rights under contracts with our portfolio companies. Our business is also subject to extensive regulation, which may result in regulatory proceedings against us.

Item 1A. Risk Factors.

There have been no material changes to the risk factors discussed in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2023.

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

In February 2023, the Board approved a share repurchase plan, under which the Company was authorized to repurchase up to $250 million in the aggregate of its outstanding Common Shares in the open market at prices below the Company's NAV per share for a one-year term, in accordance with the guidelines specified in Rule 10b-18 of the Exchange Act (the “10b-18 Plan”). The 10b-18 Plan was not renewed and terminated by its terms on February 22, 2024.

For the three months ended March 31, 2024, the Company did not repurchase any of its shares under the 10b-18 Plan.

Exhibit 99.1

Section 13(r) Disclosure

The disclosure reproduced below was initially included in the Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission by Blackstone Inc. (“Blackstone”) with respect to its quarter ended March 31, 2024, in accordance with Section 13(r) of the Securities Exchange Act of 1934, as amended, in regard to Mundys S.p.A. (formerly, Atlantia S.PA.). Mundys S.p.A. may be, or may have been at the time considered to be, an affiliate of Blackstone, and therefore an affiliate of Blackstone Secured Lending Fund (“BXSL”). BXSL did not independently verify or participate in the preparation of the disclosure reproduced below.

Blackstone included the following disclosure in its Quarterly Report on Form 10-Q for the quarter ended March 31, 2024:

Mundys S.p.A. (formerly “Atlantia S.p.A.”) provided the disclosure reproduced below in connection with activities during the quarter ended March 31, 2024. We have not independently verified or participated in the preparation of this disclosure.

“Disclosure pursuant to Section 13(r) of the Securities Exchange Act of 1934. Funds affiliated with Blackstone first invested in Mundys S.p.A. on November 18, 2022 in connection with the voluntary public tender offer by Schema Alfa S.p.A. for all of the shares of Mundys S.p.A., pursuant to which such funds obtained a minority non-controlling interest in Mundys S.p.A. Mundys S.p.A. owns and controls Aeroporti di Roma S.p.A. (“ADR”), an operator of airports in Italy including Leonardo da Vinci-Fiumicino Airport. Iran Air has historically operated periodic flights to and from Leonardo da Vinci-Fiumicino Airport as authorized, from time to time, by an aviation-related bilateral agreement between Italy and Iran, scheduled in compliance with European Regulation 95/93, and approved by the Italian Civil Aviation Authority. ADR, as airport operator, is under a mandatory obligation to provide airport services to all air carriers (including Iran Air) authorized by the applicable Italian authority. The relevant turnover attributable to these activities (whose consideration is calculated on the basis of general tariffs determined by such independent Italian authority) in the quarter ended March 31, 2024 was less than €70,000. Mundys S.p.A. does not track profits specifically attributable to these activities.”

Organization

Organization

Blackstone Secured Lending Fund (together with its consolidated subsidiaries, the “Company”), is a Delaware statutory trust formed on March 26, 2018, and structured as an externally managed, non-diversified, closed-end management investment company. On October 26, 2018, the Company elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (together with the rules and regulations promulgated thereunder, the “1940 Act”). In addition, the Company has elected to be treated for U.S. federal income tax purposes, and intends to qualify annually, as a regulated investment company (a “RIC”), under Subchapter M of the Internal Revenue Code of 1986, as amended (together with the rules and regulations promulgated thereunder, the “Code”).

The Company is externally managed by Blackstone Credit BDC Advisors LLC (the “Adviser”) an affiliate of Blackstone Alternative Credit Advisors LP (the “Administrator” and, collectively with its affiliates in the credit, asset-based finance, and insurance asset management business unit of Blackstone Inc. (“Blackstone”), “Blackstone Credit & Insurance,” or “BXCI”). The Administrator provides certain administrative and other services necessary for the Company to operate pursuant to an administration agreement (the “Administration Agreement”). References herein to information about Blackstone Credit & Insurance from December 31, 2023 or prior refers solely to the Adviser and Blackstone Alternative Credit Advisors LP, collectively with their credit-focused affiliates within Blackstone Credit & Insurance.

The Company’s investment objectives are to generate current income and, to a lesser extent, long-term capital appreciation. The Company seeks to achieve its investment objectives primarily through originated loans and other securities, including syndicated loans, of private U.S. companies, typically in the form of first lien senior secured and unitranche loans (including first out/last out loans), and to a lesser extent, second lien, third lien, unsecured and subordinated loans and other debt and equity securities.

The Company commenced its loan origination and investment activities on November 20, 2018.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Basis of Presentation

The condensed consolidated financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States (“GAAP”). As an investment company, the Company applies the accounting and reporting guidance in Accounting Standards Codification (“ASC”) Topic 946, “Financial Services – Investment Companies” (“ASC 946”) issued by the Financial Accounting Standards Board (“FASB”).

The interim condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 6 and Article 10 of Regulation S-X. Accordingly, certain disclosures accompanying the annual consolidated financial statements prepared in accordance with GAAP are omitted. In the opinion of management, all adjustments considered necessary for the fair presentation of the condensed consolidated financial statements for the interim period presented, have been included. The current period’s results of operations will not necessarily be indicative of results that ultimately may be achieved for the fiscal year ending December 31, 2024.

All intercompany balances and transactions have been eliminated.

Certain prior period information has been reclassified to conform to the current period presentation.

Use of Estimates

The preparation of condensed 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 condensed consolidated financial statements. Such amounts could differ from those estimates and such differences could be material. Assumptions and estimates regarding the valuation of investments involve a higher degree of judgment and complexity and these assumptions and estimates may be significant to the condensed consolidated financial statements. Actual results may ultimately differ from those estimates.

Consolidation

As provided under ASC 946, the Company will 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.

The Company consolidated the results of the Company’s wholly-owned subsidiaries which are considered to be investment companies. As of March 31, 2024 and December 31, 2023, the Company's consolidated subsidiaries were BGSL Jackson Hole Funding LLC (“Jackson Hole Funding”), BGSL Breckenridge Funding LLC (“Breckenridge Funding”), BGSL Big Sky Funding LLC (“Big Sky Funding”), BGSL Investments LLC (“BGSL Investments”), BXSL Associates GP (Lux) S.à r.l, BXSL Direct Lending (Lux) SCSp, BXSL C-1 LLC, and BXSL C-2 Funding LLC.

Cash and Cash Equivalents

Cash and cash equivalents consist of demand deposits and highly liquid investments, such as money market funds, with original maturities of three months or less. Cash and cash equivalents are carried at cost, which approximates fair value. The Company deposits its cash and cash equivalents with financial institutions and, at times, may exceed the Federal Deposit Insurance Corporation insured limit.

Investments

Investment transactions are recorded on a trade date basis.

Realized gains or losses are measured by the difference between the net proceeds received (excluding prepayment fees, if any) and the amortized cost basis of the investment using the specific identification method without regard to unrealized gains or losses previously recognized, and include investments charged off during the period, net of recoveries, and is recorded within Net realized gain (loss) on the Condensed Consolidated Statements of Operations.

The net change in unrealized gains or losses primarily reflects the change in investment values, including the reversal of previously recorded unrealized gains or losses with respect to investments realized during the period, and is recorded within Net change in unrealized appreciation (depreciation) on the Condensed Consolidated Statements of Operations.

Valuation of Investments

The Company is required to report its investments, including those for which current market values are not readily available, at fair value.

The Company values its investments in accordance with ASC 820, Fair Value Measurements (“ASC 820”), which defines fair value as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the applicable measurement date, and Rule 2a-5 under the 1940 Act.

Under ASC 820, fair value is based on observable market prices or parameters or derived from such prices or parameters when such quotations are readily available. In accordance with Rule 2a-5 under the 1940 Act, fair value means the value of a portfolio investment for which market quotations are not readily available. A market quotation is “readily available” only when it is a quoted price (unadjusted) in active markets for identical instruments that a fund can access at the measurement date, provided that such a quotation is not considered to be readily available if it is not reliable.

Where prices or inputs are not available or, in the judgment of the Board, with assistance of the Adviser, the Audit Committee and independent valuation firm(s), determine to be not reliable, valuation techniques based on the facts and circumstances of the particular investment will be utilized. These valuation approaches involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the investments or market and the investments’ complexity. In the absence of observable, reliable market prices, the Company values its investments using various valuation methodologies applied on a consistent basis.

An enterprise value (“EV”) analysis is generally performed to determine the value of equity investments, control debt investments and non-control debt investments that are credit-impaired, and to determine if debt investments are credit-impaired. The Adviser will generally utilize approaches including the market approach, the income approach or both approaches, as appropriate, when calculating EV. The primary method for determining EV for non-control investments, and control investments without reliable projections, uses a multiple analysis whereby appropriate multiples are applied to the portfolio company’s earnings before interest, taxes, depreciation and amortization (“EBITDA”) or another key financial metric (e.g., such as revenues, cash flows or net income) (“Performance Multiple”). Performance Multiples are typically determined based upon a review of publicly-traded comparable companies and market comparable transactions, if any. The second method for determining EV (and primary method for control investments with reliable projections) uses a discounted cash flow analysis whereby future expected cash flows and the anticipated terminal value of the portfolio company are discounted to determine a present value using estimated discount rates. The income approach is generally used when the Adviser has visibility into the long term projected cash flows of a portfolio company.

If debt investments are credit-impaired, which occurs when there is insufficient coverage under the enterprise value analysis through the respective investment’s position in the capital structure, the Adviser generally uses the enterprise value “waterfall” approach or a recovery method (if a liquidation or restructuring is deemed likely) to determine fair value. For debt investments that are not determined to be credit-impaired, the Adviser generally uses a market interest rate yield analysis to determine fair value. To determine fair value using a yield analysis, the expected cash flows are projected based on the contractual terms of the debt security and discounted back to the measurement date based on a market yield. A market yield is determined based upon an assessment of current and expected market yields for similar investments and risk profiles. The Company considers the current contractual interest rate, the maturity and other terms of the investment relative to risk of the company and the specific investment. A key determinant of risk, among other things, is the leverage through the investment relative to the enterprise value of the portfolio company. As debt investments held by the Company are substantially illiquid with no active transaction market, the Company depends on primary market data, including newly funded transactions, as well as secondary market data with respect to high yield debt instruments and syndicated loans, as inputs in determining the appropriate market yield, as applicable. The fair value of loans with call protection is generally capped at par plus applicable prepayment premium in effect at the measurement date.

ASC 820 prioritizes the use of observable market prices derived from such prices. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The levels used for classifying investments are not necessarily an indication of the risk associated with investing in these securities. The three levels of the fair value hierarchy are as follows:

•Level 1: Inputs to the valuation methodology are quoted prices available in active markets for identical instruments as of the reporting date. The types of financial instruments included in Level 1 include unrestricted securities, including equities and derivatives, listed in active markets.

•Level 2: Inputs to the valuation methodology are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date. The types of financial instruments in this category include less liquid and restricted securities listed in active markets, securities traded in other than active markets, government and agency securities and certain over-the-counter derivatives where the fair value is based on observable inputs.

•Level 3: Inputs to the valuation methodology are unobservable and significant to overall fair value measurement. The inputs into the determination of fair value require significant management judgment or estimation. Financial instruments that are included in this category include debt and equity investments in privately held entities, collateralized loan obligations (“CLOs”) and certain over-the-counter derivatives where the fair value is based on unobservable inputs.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the overall fair value measurement. The Board’s assessment, with the assistance of the Adviser, the Audit Committee and independent valuation firm(s), of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment. Transfers between levels, if any, are recognized at the beginning of the quarter in which the transfer occurs.

The Company evaluates the source of the inputs, including any markets in which its investments are trading (or any markets in which securities with similar attributes are trading), in determining fair value. When an investment is valued based on prices provided by reputable dealers or pricing services (that is, broker quotes), the Company subjects those prices to various criteria in making the determination as to whether a particular investment would qualify for treatment as a Level 2 or Level 3 investment.

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 Company’s investments may fluctuate from period to period, and these differences could be material. Additionally, the fair value of the Company’s investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that the Company may ultimately realize. Further, such investments are generally subject to legal and other restrictions on resale or otherwise are less liquid than publicly-traded securities. If the Company was required to liquidate a portfolio investment in a forced or liquidation sale, it could realize significantly less than the value at which the Company has recorded it. In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the unrealized gains or losses reflected in the valuations currently assigned. See “Item 2. Management’s Discussion and Analysis of Financial Conditions and Results of Operations—Critical Accounting Estimates.”

Receivables/Payables From Investments Sold/Purchased

Receivables/payables from investments sold/purchased consist of amounts receivable to or payable by the Company for transactions that have not settled at the reporting date.

Derivative Instruments

The Company recognizes all derivative instruments as assets or liabilities at fair value in its condensed consolidated financial statements. Derivative contracts entered into by the Company are not designated in hedge accounting relationships and all changes in fair value are recognized through current period gains or losses.

In the normal course of business, the Company has commitments and risks resulting from its investment transactions, which may include those involving derivative instruments. Derivative instruments are measured in terms of the notional contract amount and derive their value based upon one or more underlying instruments. While the notional amount gives some indication of the Company’s derivative activity, it generally is not exchanged, but is only used as the basis on which interest and other payments are exchanged. Derivative instruments are subject to various risks similar to non-derivative instruments including market, credit, liquidity, and operational risks. The Company manages these risks on an aggregate basis as part of its risk management process.

Forward Purchase Agreement

Forward purchase agreements are recognized at fair value through current period gains or losses on the date on which the contract is entered into and are subsequently re-measured at fair value. All forward purchase agreements are carried as assets when fair value is positive and as liabilities when fair value is negative. A forward purchase agreement is derecognized when the obligation specified in the contract is discharged, canceled or expired.

Foreign Currency Transactions

Amounts denominated in foreign currencies are translated into U.S. dollars on the following basis: (i) investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates effective on the last business day of the period; and (ii) purchases and sales of investments, borrowings and repayments of such borrowings, income, and expenses denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates prevailing on the transaction dates.

The Company includes net changes in fair values on investments held resulting from foreign exchange rate fluctuations in Translation of assets and liabilities in foreign currencies on the Condensed Consolidated Statements of Operations, if any. Foreign security and currency translations may involve certain considerations and risks not typically associated with investing in U.S. companies and U.S. government securities. 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.

Revenue Recognition

Interest Income

Interest income is recorded on an accrual basis and includes the accretion of discounts and amortizations of premiums. Discounts from and premiums to par value on debt investments purchased are accreted/amortized into interest income over the life of the respective security using the effective interest method. The amortized cost of debt investments represents the original cost, including loan origination fees and upfront fees received that are deemed to be an adjustment to yield, adjusted for the accretion of discounts and amortization of premiums, if any. Upon prepayment of a loan or debt security, any prepayment premiums, unamortized upfront loan origination fees and unamortized discounts are recorded as interest income in the current period. For the three months ended March 31, 2024 and 2023, the Company recorded $1.9 million and $0.4 million, respectively, in non-recurring interest income (e.g., prepayment premiums, accelerated accretion of upfront loan origination fees and unamortized discounts).

PIK Income

The Company has loans in its portfolio that contain payment-in-kind (“PIK”) provisions. PIK represents interest that is accrued and recorded as interest income at the contractual rates, increases the loan principal on the respective capitalization dates, and is generally due at maturity. Such income is included in payment-in-kind interest income in the Condensed Consolidated Statements of Operations. If at any point the Company believes PIK is not expected to be realized, the investment generating PIK will be placed on non-accrual status. When a PIK investment is placed on non-accrual status, the accrued, uncapitalized interest is generally reversed through payment-in-kind interest income. To satisfy the Company’s annual RIC distribution requirements, this non-cash source of income must be included in determining the amounts to be paid out to shareholders in the form of dividends, even though the Company has not yet collected cash.

Dividend Income

Dividend income on preferred equity securities is recorded on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. 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.

Fee Income

The Company may receive various fees in the ordinary course of business such as structuring, consent, waiver, amendment, syndication and other miscellaneous fees as well as fees for managerial assistance rendered by the Company to the portfolio companies. Such fees are recognized as income when earned or the services are rendered.

Non-Accrual Income

Loans are generally placed on non-accrual status when there is reasonable doubt whether principal or interest will be collected in full. Accrued interest is generally reversed when a loan is placed on non-accrual status. Additionally, any original issue discount and market discount are no longer accreted to interest income as of the date the loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. Non-accrual loans are restored to accrual status when past due principal and interest is paid current and, in management’s judgment, are likely to remain current. Management may make exceptions to this treatment and determine to not place a loan on non-accrual status if the loan has sufficient collateral value and is in the process of collection.

For further information regarding the non-accrual status of investments refer to “Note 4. Investments”.

Organization Expenses and Offering Expenses

The Company records expenses related to public equity offerings as a reduction of capital upon completion of an offering of registered securities. The costs associated with any renewals of a shelf registration statement will be expensed as incurred.

Deferred Financing Costs and Debt Issuance Costs

Deferred financing and debt issuance costs represent fees and other direct incremental costs incurred in connection with the Company’s borrowings. These expenses are deferred and amortized into interest expense over the life of the related debt instrument. Deferred financing costs related to revolving credit facilities are presented separately as an asset on the Company’s Condensed Consolidated Statements of Assets and Liabilities. Debt issuance costs related to any issuance of installment debt or notes are presented net against the outstanding debt balance of the related security.

Income Taxes

The Company has elected to be treated as a BDC under the 1940 Act. The Company also has elected to be treated as a RIC under the Code. So long as the Company maintains its status as a RIC, it generally will not pay corporate-level U.S. federal income taxes on any ordinary income or capital gains that it distributes at least annually to its shareholders as dividends. Rather, any tax liability related to income earned and distributed by the Company would represent obligations of the Company’s investors and would not be reflected in the condensed consolidated financial statements of the Company.

The Company evaluates tax positions taken or expected to be taken in the course of preparing its condensed consolidated financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are reserved and recorded as a tax benefit or expense in the current year. All penalties and interest associated with income taxes are included in income tax expense. Conclusions regarding tax positions are subject to review and may be adjusted at a later date based on factors including, but not limited to, on-going analyses of tax laws, regulations and interpretations thereof.

To qualify for and maintain qualification as a RIC, the Company must, among other things, meet certain source-of-income and asset diversification requirements. In addition, to qualify for taxation as a RIC, the Company must distribute to its shareholders, for each taxable year, at least 90% of the sum of (i) its “investment company taxable income” for that year (without regard to the deduction for dividends paid), which is generally its ordinary income plus the excess, if any, of its realized net short-term capital gains over its realized net long-term capital losses and (ii) its net tax-exempt income.

In addition, based on the excise tax distribution requirements, the Company is subject to a 4% nondeductible federal excise tax on certain undistributed income unless the Company distributes in a timely manner in each taxable year an amount at least equal to the sum of (i) 98% of its ordinary income for the calendar year, (ii) 98.2% of its capital gain net income (both long-term and short-term) for the one-year period ending October 31 in that calendar year and (iii) any income realized, but not distributed, in prior years. For this purpose, however, any ordinary income or capital gain net income retained by the Company that is subject to corporate income tax is considered to have been distributed.

For the three months ended March 31, 2024 and 2023, the Company incurred $3.4 million and $2.6 million, respectively, of U.S. federal excise tax.

Distributions

To the extent that the Company has taxable income available, the Company intends to make quarterly distributions to its shareholders. Distributions to shareholders are recorded on the record date. All distributions will be paid at the discretion of the Board and will depend on the Company’s earnings, financial condition, maintenance of the Company's tax treatment as a RIC, compliance with applicable BDC regulations and such other factors as the Board may deem relevant from time to time.

Recent Accounting Pronouncements

In June 2022, the FASB issued Accounting Standards Update (“ASU”) 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions” (“ASU 2022-03”), which clarifies guidance for fair value measurement of an equity security subject to a contractual sale restriction and establishes new disclosure requirements for such equity securities. ASU 2022-03 is effective for fiscal years beginning after December 15, 2023 and for interim periods within those fiscal years, and has been adopted by the Company beginning with the condensed consolidated financial statements as of and for the three months ended March 31, 2024. The adoption of this guidance did not have a material impact on the Company’s condensed consolidated financial statements.

In November 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” (“ASU 2023-07”). ASU 2023-07 enhances the disclosures required for reportable segments on an annual and interim basis. ASU 2023-07 is effective on a retrospective basis for annual periods beginning after December 15, 2023, for interim periods within fiscal years beginning after December 15, 2024, and early adoption is permitted. The Company does not expect the adoption of ASU 2023-07 to have a material impact on its consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” (“ASU 2023-09”). ASU 2023-09 requires additional disaggregated disclosures on the entity’s effective tax rate reconciliation and additional details on income taxes paid. ASU 2023-09 is effective on a prospective basis, with the option for retrospective application, for annual periods beginning after December 15, 2024 and early adoption is permitted. The Company does not expect the adoption of ASU 2023-09 to have a material impact on its consolidated financial statements.

Agreements and Related Party Transactions

Agreements and Related Party Transactions

Investment Advisory Agreement

On October 1, 2018, the Company entered into the original investment advisory agreement with the Adviser. The Adviser is responsible for originating prospective investments, conducting research and due diligence investigations on potential investments, analyzing investment opportunities, negotiating and structuring the Company’s investments and monitoring its investments and portfolio companies on an ongoing basis.

On October 18, 2021, the Company entered into an amended and restated investment advisory agreement (as amended and restated, the “Investment Advisory Agreement”), pursuant to which the Adviser manages the Company on a day-to-day basis. The Investment Advisory Agreement is substantially the same as the prior investment advisory agreement except, following the IPO, the incentive fee on income became subject to a twelve-quarter lookback quarterly hurdle rate of 1.50% as opposed to a single quarter measurement and became subject to an Incentive Fee Cap (as defined below) based on the Company’s Cumulative Net Return (as defined below). The amendment to the Investment Advisory Agreement does not result in higher fees (on a cumulative basis) payable to the Adviser than the fees that would have otherwise been payable to the Adviser under the original investment advisory agreement.

The Company pays the Adviser a fee for its services under the Investment Advisory Agreement consisting of two components: a management fee and an incentive fee. The cost of both the management fee and the incentive fee is borne by the shareholders. The initial term of the Investment Advisory Agreement was two years from October 1, 2018, and on May 6, 2020 and May 6, 2021, it was renewed and approved by the Board, including a majority of trustees who are not parties to the Investment Advisory Agreement or “interested persons” (as such term is defined in Section 2(a)(19) of the 1940 Act) (the “Independent Trustees”), for a one-year period. On October 18, 2021, the Board approved the amended and restated Investment Advisory Agreement. Unless earlier terminated, the Investment Advisory Agreement will renew automatically for successive annual periods, provided that such continuance is specifically approved at least annually by the vote of the Board and by the vote of a majority of the Independent Trustees. The Investment Advisory Agreement was most recently renewed and approved by the Board, including majority of the Independent Trustees, on May 1, 2024 for a one-year period ending on May 31, 2025.

The Adviser implemented a waiver effective from the consummation of the IPO to extend the Company’s pre-IPO fee structure for a period of two years. With the waiver in place, instead of having the base management fee and each incentive fee increase to 1.00% and 17.5%, respectively, following the IPO, each such fee remained at 0.75% and 15.0% for a period of two years following the IPO (the “Waiver Period”). As a result of the fee waiver, the pre-listing management fee and incentive fee rates paid by the Company to the Adviser did not increase during the Waiver Period. Amounts waived by the Adviser are not subject to recoupment by the Adviser. The Waiver Period ended on October 28, 2023.

Base Management Fees

Starting from the consummation of the IPO, the management fee pursuant to the Investment Advisory Agreement is payable quarterly in arrears at an annual rate of 1.0% of the average value of the Company’s “gross assets” at the end of the two most recently completed calendar quarters. For purposes of the Investment Advisory Agreement, “gross assets” means the Company’s total assets determined on a consolidated basis in accordance with GAAP, excluding undrawn commitments but including assets purchased with borrowed amounts. The management fee was calculated for the quarter ended December 31, 2021, and the quarter ended December 31, 2023, at a weighted rate calculated based on the fee rates applicable before and after the consummation of the IPO and the expiration of the Waiver Period based on the number of days in the calendar quarter before and after the consummation of the IPO and the expiration of the Waiver Period.

Prior to the consummation of the IPO, the management fee was 0.75% of the average value of the Company’s gross assets at the end of the two most recently completed calendar quarters. In order to maintain the same management fee arrangement that the Company had in place prior to the IPO for a period of time following the consummation of the IPO, the Adviser voluntarily waived its right to receive the base management fee in excess of 0.75% of the average value of the Company’s gross assets at the end of the two most recently completed calendar quarters during the Waiver Period. Amounts waived by the Adviser are not subject to recoupment by the Adviser.

For the three months ended March 31, 2024 and 2023, base management fees were $26.0 million and $24.7 million, respectively, of which $0.0 million and $6.2 million, respectively, were waived. The Waiver Period ended on October 28, 2023.

As of March 31, 2024 and December 31, 2023, $26.0 million and $23.0 million, respectively, was payable to the Adviser relating to management fees.

Incentive Fees

The incentive fees consist of two components that are determined independently of each other, with the result that one component may be payable even if the other is not. One component is based on income and the other component is based on capital gains, each as described below:

(i) Income based incentive fees:

The first part of the incentive fee, an income based incentive fee, is calculated and payable quarterly in arrears based on the Company’s Pre-Incentive Fee Net Investment Income Returns as defined in the Investment Advisory Agreement. 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 the Company’s net assets at the end of the immediately preceding quarter 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 the Company receives from portfolio companies) accrued during the calendar quarter, minus the Company’s 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. Pre-Incentive Fee Net Investment Income Returns includes, 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 the Company has not yet received in cash. Pre-incentive fee net investment income excludes any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. The Company excludes the impact of expense support payments and recoupments from pre-incentive fee net investment income. Shareholders may be charged a fee on an income amount that is higher than the income they may ultimately receive.

Pre-Incentive Fee Net Investment Income Returns, expressed as a rate of return on the value of our net assets at the end of the immediately preceding quarter, is compared to a “hurdle rate” of return of 1.5% per quarter (6.0% annualized).

Pursuant to the Investment Advisory Agreement, the Company is required to pay an income based incentive fee of 17.5% (15% prior to the consummation of the IPO), with a 1.5% hurdle and 100% catch-up. However, the Adviser implemented a voluntary waiver with respect to the income based incentive fee during the Waiver Period. The Adviser voluntarily waived its right to receive an income based incentive fee above 15% during the Waiver Period and amounts waived by the Adviser were not subject to recoupment by the Adviser.

The Company pays the Adviser an income based incentive fee based on its aggregate pre-incentive fee net investment income, as adjusted as described above, from the calendar quarter then ending and the eleven preceding calendar quarters (such period, the “Trailing Twelve Quarters”).

The hurdle amount for the income based incentive fee is determined on a quarterly basis and is equal to 1.5% multiplied by the Company’s NAV at the beginning of each applicable calendar quarter comprising the relevant Trailing Twelve Quarters. The hurdle amount is calculated after making appropriate adjustments for issuances by the Company of Common Shares, including issuances pursuant to its dividend reinvestment plan (“DRIP”) and distributions that occurred during the relevant Trailing Twelve Quarters. The income based incentive fee for any partial period will be appropriately prorated.

For the income based incentive fee, the Company will pay the Adviser a quarterly incentive fee based on the amount by which (A) aggregate pre-incentive fee net investment income in respect of the relevant Trailing Twelve Quarters exceeds (B) the hurdle amount for such Trailing Twelve Quarters. The amount of the excess of (A) over (B) described in this paragraph for such Trailing Twelve Quarters is referred to as the “Excess Income Amount”.

The income based incentive fee for each quarter will be determined as follows:

•No income based incentive fee is payable to the Adviser for any calendar quarter for which there is no Excess Income Amount.

•The Adviser will be paid 100% of the pre-incentive fee net investment income in respect of the Trailing Twelve Quarters, if any, that exceeds the hurdle amount for such Trailing Twelve Quarters, but is less than or equal to an amount, which we refer to as the “Catch-up Amount,” determined as the sum of 1.82% (7.27% annualized) (1.76% (7.06% annualized) during the Waiver Period), multiplied by the Company’s NAV at the beginning of each applicable calendar quarter comprising the relevant Trailing Twelve Quarters that is included in the calculation of the incentive fee based on income.

•The Adviser will be paid 17.5% (15% during the Waiver Period), of the pre-incentive fee net investment income in respect of the Trailing Twelve Quarters that exceeds the Catch-up Amount.

The amount of the income based incentive fee that will be paid to the Adviser for a particular quarter will equal the excess of (a) the income based incentive fee so calculated over (b) the aggregate income based incentive fee that was paid in respect of the first eleven calendar quarters included in the relevant Trailing Twelve Quarters subject to the Incentive Fee Cap as described below.

The income based incentive fee that will be paid to the Adviser for a particular quarter is subject to a cap (the “Incentive Fee Cap”). The Incentive Fee Cap for any quarter is an amount equal to (a) 17.5% (15% prior to the end of the Waiver Period), of the Cumulative Net Return (as defined below) during the relevant Trailing Twelve Quarters minus (b) the aggregate income based incentive fee that was paid in respect of the first eleven calendar quarters (or the portion thereof) included in the relevant Trailing Twelve Quarters.

“Cumulative Net Return” means (x) the pre-incentive fee net investment income in respect of the relevant Trailing Twelve Quarters minus (y) any Net Capital Loss (as defined below), if any, in respect of the relevant Trailing Twelve Quarters. If, in any quarter, the Incentive Fee Cap is zero or a negative value, the Company will pay no income based incentive fee to the Adviser for such quarter. If, in any quarter, the Incentive Fee Cap for such quarter is a positive value but is less than the income based incentive fee that is payable to the Adviser for such quarter (before giving effect to the Incentive Fee Cap) calculated as described above, the Company will pay an income based incentive fee to the Adviser equal to the Incentive Fee Cap for such quarter. If, in any quarter, the Incentive Fee Cap for such quarter is equal to or greater than the income based incentive fee that is payable to the Adviser for such quarter (before giving effect to the Incentive Fee Cap) calculated as described above, the Company will pay an income based incentive fee to the Adviser equal to the incentive fee calculated as described above for such quarter without regard to the Incentive Fee Cap.

“Net Capital Loss” in respect of a particular period means the difference, if positive, between (i) aggregate capital losses, whether realized or unrealized, in such period and (ii) aggregate capital gains, whether realized or unrealized, in such period.

These calculations are prorated for any period of less than three months and adjusted for any share issuances or repurchases during the relevant quarter. As the consummation of the IPO occurred on a date other than the first day of a calendar quarter, the income based incentive fee with respect to the Company’s pre-incentive fee net investment income was calculated for such calendar quarter at a weighted rate calculated based on the fee rates applicable before and after the consummation of the IPO based on the number of days in such calendar quarter before and after the consummation of the IPO. In no event will the amendments to the income based incentive fee include the incentive fee cap and allow the Adviser to receive greater cumulative income based incentive fees under the Investment Advisory Agreement than it would have under the prior investment advisory agreement. Amounts waived by the Adviser are not subject to recoupment by the Adviser.

(ii) Capital gains based incentive fee:

Starting from the completion of the IPO, the second part of the incentive fee, a capital gains incentive fee, is determined and payable in arrears as of the end of each calendar year in an amount equal to 17.5% of realized capital gains, if any, on a cumulative basis 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 fees as calculated in accordance with GAAP.

Prior to the IPO, the second part of the incentive fee, a capital gains incentive fee, was determined and payable in arrears as of the end of each calendar year in an amount equal to 15.0% of realized capital gains, if any, on a cumulative basis 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 fees as calculated in accordance with GAAP. However, similar to the voluntary waivers referenced above, the Adviser voluntarily waived its right to receive a capital gains based incentive fee above 15% from the date of consummation of the IPO through the Waiver Period. The Company will accrue, but will not pay, a capital gains incentive fee with respect to unrealized appreciation because a capital gains incentive fee would be owed to the Adviser if the Company were to sell the relevant investment and realize a capital gain. Amounts waived by the Adviser are not subject to recoupment by the Adviser.

For the three months ended March 31, 2024 and 2023, the Company accrued income based incentive fees of $35.8 million and $30.4 million, respectively, of which $0.0 million and $4.3 million, respectively, were waived. The Waiver Period ended on October 28, 2023.

As of March 31, 2024 and December 31, 2023, $35.8 million and $34.4 million, respectively, was payable to the Adviser for income based incentive fees.

For the three months ended March 31, 2024, the Company accrued capital gains incentive fees of $3.1 million. For the three months ended March 31, 2023, the Company reversed previously accrued capital gains incentive fee of $(1.6) million.

Administration Agreement

On October 1, 2018, the Company entered into an Administration Agreement with the Administrator. Under the terms of the Administration Agreement, the Administrator provides, or oversees the performance of, administrative and compliance services, including, but not limited to, maintaining financial records, overseeing the calculation of NAV, compliance monitoring (including diligence and oversight of the Company’s other service providers), preparing reports to shareholders and reports filed with the United States Securities and Exchange Commission (“SEC”), preparing materials and coordinating meetings of the Company’s Board, managing the payment of expenses and the performance of administrative and professional services rendered by others and providing office space, equipment and office services. The Administrator may also offer to provide, on the Company’s behalf, managerial assistance to the Company’s portfolio companies. The initial term of the agreement was two years from October 1, 2018. Unless earlier terminated, the Administration Agreement will renew automatically for successive annual periods, provided that such continuance is approved at least annually by (i) the vote of the Board or by a majority vote of the outstanding voting securities of the Company and (ii) the vote of a majority of the Independent Trustees. The Administration Agreement was most recently renewed and approved by the Board, including a majority of the Independent Trustees, on May 1, 2024, for a one-year period.

For providing these services, the Company will reimburse the Administrator for its costs, expenses and allocable portion of overhead (including rent, office equipment and utilities) and other expenses incurred by the Administrator in performing its administrative obligations under the Administration Agreement, including but not limited to: (i) the Company’s chief compliance officer, chief financial officer and their respective staffs; (ii) investor relations, legal, operations and other non-investment professionals (including information technology professionals) at the Administrator that perform duties for the Company; and (iii) any internal audit group personnel of Blackstone or any of its affiliates. The Administrator has elected to forgo any reimbursement for rent and other occupancy costs for the three months ended March 31, 2024 and 2023.

For the three months ended March 31, 2024 and 2023, the Company incurred $0.7 million and $0.4 million, respectively, in expenses under the Administration Agreement, which were recorded in Administrative service expenses in the Company’s Condensed Consolidated Statements of Operations.

As of March 31, 2024 and December 31, 2023, $0.6 million and $1.1 million, respectively, was unpaid and included in Due to affiliates in the Condensed Consolidated Statements of Assets and Liabilities.

Sub-Administration and Custody Agreement

On October 1, 2018, the Administrator entered into a sub-administration agreement (the “Sub-Administration Agreement”) with State Street Bank and Trust Company (the “Sub-Administrator”) under which the Sub-Administrator provides various accounting and administrative services to the Company. The Sub-Administrator also serves as the Company’s custodian (the “Custodian”). The initial term of the Sub-Administration Agreement is two years from the effective date and after expiration of the initial term and the Sub-Administration Agreement shall automatically renew for successive one-year periods, unless a written notice of non-renewal is delivered prior to 120 days prior to the expiration of the initial term or renewal term.

Expense Support and Conditional Reimbursement Agreement

On December 12, 2018, the Company entered into an Expense Support and Conditional Reimbursement Agreement (the “Expense Support Agreement”) with the Adviser pursuant to which the Adviser was able to elect to pay certain expenses of the Company on the Company’s behalf (each, an “Expense Payment”), provided that no portion of the payment was used to pay any interest of the Company. Any Expense Payment that the Adviser committed to pay was to be paid by the 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 Adviser or its affiliates.

Pursuant to the Expense Support Agreement, following any calendar quarter in which Available Operating Funds (as defined below) exceeded the cumulative distributions accrued to the Company’s shareholders based on distributions declared with respect to record dates occurring in such calendar quarter (the “Excess Operating Funds”), the Company was required to pay such Excess Operating Funds, or a portion thereof, to the Adviser until such time as all Expense Payments made by the Adviser to the Company within three years prior to the last business day of such calendar quarter were reimbursed. Any payments required to be made by the Company to the Adviser are referred to herein as a “Reimbursement Payment”. Available Operating Funds means the sum of (i) the Company’s net investment company taxable income (including net short-term capital gains reduced by net long-term capital losses), (ii) the Company’s 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 Expense Support Agreement terminated by its own terms on October 28, 2021. The Company’s obligation to make Reimbursement Payments survived the termination of the Expense Support Agreement and may be made for a period of up to three years, in accordance with the terms of the Expense Support Agreement. The Company’s obligation to make a Reimbursement Payment becomes a liability of the Company on the last business day of the applicable calendar quarter. As of March 31, 2024 and 2023, there are no amounts subject to the Reimbursement Payment obligation.

As of March 31, 2024 and 2023, there was no unreimbursed Expense Payments. For the three months ended March 31, 2024 and 2023, the Adviser made no Expense Payments and the Company made no Reimbursement Payments related to Expense Payments by the Adviser.

(1)Weighted averages are calculated based on fair value of investments.

The significant unobservable input used in the yield analysis is the discount rate based on comparable market yields. The significant unobservable input used for market quotations are broker quoted prices provided by independent pricing services. The significant unobservable input used under the market approach is the Performance Multiple. Significant increases in discount rates would result in a significantly lower fair value measurement. Significant decreases in quoted prices or Performance Multiples would result in a significantly lower fair value measurement.

Borrowings

Borrowings

In accordance with the 1940 Act, with certain limitations, the Company is allowed to borrow amounts such that its asset coverage, as defined in the 1940 Act, is at least 150% after such borrowing. As of March 31, 2024 and December 31, 2023, the Company’s asset coverage was 197.3% and 200.3%, respectively.

SPV Financing Facilities

The following wholly-owned subsidiaries of the Company have entered into secured financing facilities, as described below: Jackson Hole Funding, Breckenridge Funding and Big Sky Funding which are collectively referred to as the “SPVs,” and such secured financing facilities described below are collectively referred to as the “SPV Financing Facilities”.

The obligations of each SPV to the lenders under the applicable SPV Financing Facility are secured by a first priority security interest in all of the applicable SPV’s portfolio investments and cash. The obligations of each SPV under the applicable SPV Financing Facility are non-recourse to the Company, and the Company’s exposure to the credit facility is limited to the value of its investment in the applicable SPV.

In connection with the SPV Financing Facilities, the applicable SPV has made certain customary representations and warranties and is required to comply with various covenants, reporting requirements and other customary requirements for similar facilities. Each SPV Financing Facility contains customary events of default for similar financing transactions, including if a change of control of the applicable SPV occurs. Upon the occurrence and during the continuation of an event of default, the lenders under the applicable SPV Financing Facility may declare the outstanding advances and all other obligations under the applicable SPV Financing Facility immediately due and payable. The occurrence of an event of default triggers a requirement that the applicable SPV obtain the consent of the lenders under the applicable SPV Financing Facility prior to entering into any sale or disposition with respect to portfolio investments.

As of March 31, 2024 and December 31, 2023, the Company was in compliance with all covenants and other requirements of each of the SPV Financing Facilities.

Jackson Hole Funding Facility

On November 16, 2018, Jackson Hole Funding, the Company’s wholly-owned subsidiary that holds primarily originated loan investments, entered into a senior secured revolving credit facility (which was subsequently amended and restated on December 16, 2021, and amended effective as of September 16, 2022, November 15, 2023 and December 18, 2023, and as further amended from time to time, the “Jackson Hole Funding Facility”) with JPMorgan Chase Bank, National Association (“JPM”). JPM serves as administrative agent, Citibank, N.A., serves as collateral agent and securities intermediary, Virtus Group, LP serves as collateral administrator and the Company serves as portfolio manager under the Jackson Hole Funding Facility.

Advances under the Jackson Hole Funding Facility bear interest at a per annum rate equal to the benchmark in effect for the currency of the applicable advances (which is the three-month Term SOFR for dollar advances), plus the applicable margin of 2.375% per annum for certain foreign currency advances to 2.525% per annum for dollar advances. Jackson Hole Funding pays a commitment fee of 0.48% per annum on the average daily unused amount of the financing commitments until November 28, 2025. Jackson Hole Funding also pays to JPM an administrative agency fee, in addition to certain other fees, each as agreed between Jackson Hole Funding and JPM.

The maximum commitment amount of the Jackson Hole Funding Facility as of March 31, 2024 was $500.0 million. The Jackson Hole Funding Facility has an accordion feature, subject to the satisfaction of various conditions, which could bring total commitments under the Jackson Hole Funding Facility to up to $900.0 million. Proceeds from borrowings under the Jackson Hole Funding Facility may be used to fund portfolio investments by Jackson Hole Funding and to make advances under delayed draw term loans where Jackson Hole Funding is a lender. The period during which Jackson Hole Funding may make borrowings under the Jackson Hole Funding Facility expires on November 28, 2025 and the Jackson Hole Funding Facility is scheduled to mature on May 17, 2027.

Breckenridge Funding Facility

On December 21, 2018, Breckenridge Funding, the Company’s wholly-owned subsidiary that holds primarily syndicated loan investments, entered into a senior secured revolving credit facility (which was subsequently amended on June 11, 2019, August 2, 2019, September 27, 2019, April 13, 2020, October 5, 2021, February 28, 2022, May 19, 2022, November 1, 2023 and January 17, 2024, and as further amended from time to time, the “Breckenridge Funding Facility”) with BNP Paribas (“BNP”).

Revolving Credit Facility

On June 15, 2020, the Company entered into a senior secured revolving credit facility (which was most recently amended on June 9, 2023, and as further amended from time to time, the “Revolving Credit Facility”) with Citibank, N.A. (“Citi”) serving as administrative agent and collateral agent.

The Revolving Credit Facility provides for borrowings in U.S. dollars and certain agreed upon foreign currencies. Borrowings under the Revolving Credit Facility are subject to compliance with a borrowing base. A portion of the Revolving Credit Facility consists of funded term loans in the aggregate principal amount of $385.0 million and the Revolving Credit Facility provides for the issuance of letters of credit on behalf of the Company in an aggregate face amount not to exceed $175.0 million. Proceeds from the borrowings under the Revolving Credit Facility may be used for general corporate purposes of the Company and its subsidiaries in the ordinary course of business. Availability of the revolver under the Revolving Credit Facility will terminate on June 28, 2027 (other than with respect to the foreign currency commitments of certain lenders in the amount of $200.0 million, which expire on June 28, 2026) and all amounts outstanding under the Revolving Credit Facility must be repaid by June 28, 2028 (other than with respect to the foreign currency commitments of certain lenders in the amount of $200.0 million which mature on June 28, 2027) pursuant to an amortization schedule.

Loans under the Revolving Credit Facility bear interest at a per annum rate equal to, (x) for loans for which the Company elects the base rate option, the “alternate base rate” (which is the greatest of (a) the prime rate as publicly announced by Citi, (b) the sum of (i) the weighted average of the rates on overnight federal funds transactions with members of the Federal Reserve System plus (ii) 0.5% and (c) one month adjusted Term SOFR plus 1% per annum) plus (A) if the gross borrowing base is equal to or greater than 1.6 times the combined revolving debt amount, 0.75%, or (B) if the gross borrowing base is less than 1.6 times the combined revolving debt amount, 0.875%, and (y) for all other loans, the applicable benchmark rate for the related interest period for such borrowing plus (A) if the gross borrowing base is equal to or greater than 1.6 times the combined revolving debt amount, 1.75%, or (B) if the gross borrowing base is less than 1.6 times the combined revolving debt amount, 1.875%. The Company will pay an unused fee of 0.375% per annum on the daily unused amount of the revolver commitments. The Company will pay letter of credit participation fees and a fronting fee on the average daily amount of any lender’s exposure with respect to any letters of credit issued under the Revolving Credit Facility.

The Company’s obligations to the lenders under the Revolving Credit Facility are secured by a first priority security interest in substantially all of the Company’s assets.

In connection with the Revolving Credit Facility, the Company has made certain customary representations and warranties and is required to comply with various covenants, reporting requirements and other customary requirements for similar facilities. In addition, the Company must comply with the following financial covenants: (a) the Company must maintain a minimum shareholders’ equity, measured as of each fiscal quarter end; and (b) the Company must maintain at all times a 150% asset coverage ratio.

The Revolving Credit Facility contains customary events of default for similar financing transactions. Upon the occurrence and during the continuation of an event of default, Citi may terminate the commitments and declare the outstanding advances and all other obligations under the Revolving Credit Facility immediately due and payable.

As of March 31, 2024 and December 31, 2023, the Company was in compliance with all covenants and other requirements of the Revolving Credit Facility.

Unsecured Notes

Shares Issued

The Company has the authority to issue an unlimited number of Common Shares at $0.001 per share par value.

On October 28, 2021, the Company priced its IPO, issuing 9,180,000 of its Common Shares at a public offering price of $26.15 per share. Net of underwriting fees, the Company received cash proceeds, before offering expenses, of $230.6 million. On November 4, 2021, the underwriters exercised their option to purchase an additional 1,377,000 shares of Common Shares, which resulted in cash proceeds, before offering expenses, of $33.8 million. The Company’s Common Shares began trading on the NYSE under the symbol “BXSL” on October 28, 2021. In connection with the listing of the Company’s Common Shares on the NYSE, the Board decided to eliminate any outstanding fractional Common Shares (the “Fractional Shares”), as permitted by Delaware law by rounding down the number of Fractional Shares held by each of our shareholders to the nearest whole share and paying each shareholder cash for such Fractional Shares.

On August 14, 2023, the Company completed a follow-on offering under its shelf registration statement, issuing 6,500,000 of its Common Shares at a price to the underwriters of $26.78 per share. Net of underwriting fees, the Company received cash proceeds, before offering expenses, of $174.1 million. On August 18, 2023, the underwriters exercised, in full, their option to purchase an additional 975,000 shares of Common Shares, which resulted in cash proceeds, before offering expenses, of $26.1 million. The Company incurred offering expenses of $0.4 million in connection with the follow-on offering.

As of March 31, 2024, the Company is party to six separate equity distribution agreements with sales agents (“Equity Distribution Agreements”), pursuant to which the Company may sell, from time to time, up to an aggregate sales price of $500.0 million of its Common Shares. Sales of Common Shares made pursuant to the Equity Distribution Agreements may be made in negotiated transactions or transactions that are deemed to be “at-the-market” offerings as defined in Rule 415(a)(5) under the Securities Act of 1933, as amended. Actual sales depend on a variety of factors including market conditions, the trading price of the Company’s Common Shares, the Company’s capital needs, and the Company’s determination of the appropriate sources of funding to meet such needs. As of March 31, 2024, Common Shares with an aggregate sales price of $500.0 million remained available for issuance under the Equity Distribution Agreements.

The following table summarizes the total Common Shares issued and proceeds received, for the three months ended March 31, 2024, through the “at-the-market” offering program (dollars in thousands except share and per share amounts):

Issuances of Common Shares	Number of Common Shares Issued	Gross Proceeds		Placement Fees/Offering Expenses		Net Proceeds		Average Share Price (1)
“At-the-market” Offering	5,885,546	$	162,726	$	704	$	162,022	$	27.53

Total distributions			$	0.7000	$	112,400

Dividend Reinvestment

The Company has adopted the DRIP, pursuant to which it reinvests all cash dividends declared by the Board on behalf of its shareholders who do not elect to receive their dividends in cash. As a result, if the Board and the Company declares, a cash dividend or other distribution, then the Company’s shareholders who have not opted out of its dividend reinvestment plan will have their cash distributions automatically reinvested in additional shares as described below, rather than receiving the cash dividend or other distribution. Starting from the consummation of the IPO, the number of shares to be issued to a shareholder is determined by dividing the total dollar amount of the cash dividend or distribution payable to a shareholder by the market price per common share at the close of regular trading on the NYSE on the payment date of a distribution, or if no sale is reported for such day, the average of the reported bid and ask prices. However, if the market price per share on the payment date of a cash dividend or distribution exceeds the most recently computed NAV per share, the Company will issue shares at the greater of (i) the most recently computed NAV per share and (ii) 95% of the current market price per share (or such lesser discount to the current market price per share that still exceeded the most recently computed NAV per share). For example, if the most recently computed NAV per share is $25.00 and the market price on the payment date of a cash dividend is $24.00 per share, the Company will issue shares at $24.00 per share. If the most recently computed NAV per share is $25.00 and the market price on the payment date of a cash dividend is $27.00 per share, the Company will issue shares at $25.65 per share (95% of the current market price). If the most recently computed NAV per share is $25.00 and the market price on the payment date of a cash dividend is $26.00 per share, the Company will issue shares at $25.00 per share.

Shareholders who receive distributions in the form of shares will generally be subject to the same U.S. federal, state and local tax consequences as if they received cash distributions; however, since their cash distributions will be reinvested, those shareholders will not receive cash with which to pay any applicable taxes. The Company intends to use newly issued shares to implement the plan.

Pursuant to our dividend reinvestment plan, the following table summarizes the amounts and shares issued to shareholders who have not opted out of the Company’s DRIP during the three months ended March 31, 2024 (dollars in thousands except share amounts):

Payment Date	DRIP Shares Value		DRIP Shares Issued
January 26, 2024	$	5,614	206,465
Total distributions	$	5,614	206,465

Total distributions	$	5,132	208,510

Share Repurchase Plan

In February 2023, the Board approved a share repurchase plan, under which the Company was authorized to repurchase up to $250 million in the aggregate of its outstanding Common Shares in the open market at prices below the Company’s NAV per share for a one-year term, in accordance with the guidelines specified in Rule 10b-18 of the Exchange Act (the “10b-18 Plan”). The 10b-18 Plan was not renewed and terminated by its terms on February 22, 2024.

For the three months ended March 31, 2024 and 2023, the Company did not repurchase any of its shares under the 10b-18 Plan.

(1)The per share data was derived by using the weighted average shares outstanding during the period.

(2)The per share data for distributions was derived by using the actual shares outstanding at the date of the relevant transactions (refer to Note 8).

(3)Total return is calculated as the change in NAV per share during the period, plus distributions per share (assuming dividends and distributions are reinvested in accordance with the Company's dividend reinvestment plan) divided by the beginning NAV per share. Total return does not include sales load.

(4)Total return based on market value is calculated as the change in market value per share during the respective periods, taking into account distributions, if any, reinvested in accordance with the Company’s dividend reinvestment plan.

(5)Amounts are annualized except for expense support amounts relating to organizational costs and management fee and income based incentive fee waivers by the Adviser (refer to Note 3). For the three months ended March 31, 2024 and 2023, the ratio of total operating expenses to average net assets was 10.7% and 11.9%, respectively, on an annualized basis, excluding the effect of expense support/(recoupment) and management fee and income based incentive fee waivers by the Adviser which represented 0.0% and (0.3)%, respectively, of average net assets. The Waiver Period ended on October 28, 2023.

General Description of Registrant [Abstract]

Investment Objectives and Practices [Text Block]

Our investment objectives are to generate current income and, to a lesser extent, long-term capital appreciation.

Under normal market conditions, we generally invest at least 80% of our total assets (net assets plus borrowings for investment purposes) in secured debt investments and our portfolio is composed primarily of first lien senior secured and unitranche loans. To a lesser extent, we have and may continue to also invest in second lien, third lien, unsecured or subordinated loans and other debt and equity securities. In limited instances we may retain the “last out” portion of a first-lien loan. In such cases, the “first out” portion of the first lien loan would receive priority with respect to payment over our “last out” position. In exchange for the higher risk of loss associated with such “last out” portion, we would earn a higher rate of interest than the “first out” position. We do not currently focus on investments in issuers that are distressed or in need of rescue financing.

Financial Condition, Liquidity and Capital Resources

Our liquidity and capital resources are generated primarily from cash flows from interest, dividends and fees earned from our investments and principal repayments, our credit facilities, debt securitization transactions, and other secured and unsecured debt. We may also generate cash flow from operations, future borrowings and future offerings of securities including public and/or private issuances of debt and/or equity securities through both registered offerings and private offerings. The primary uses of our cash and cash equivalents are for (i) originating loans and purchasing senior secured debt investments, (ii) funding the costs of our operations (including fees paid to our Adviser and expense reimbursements paid to our Administrator), (iii) debt service, repayment and other financing costs of our borrowings and (iv) cash distributions to the holders of our shares.

To facilitate public issuances of debt and/or equity securities, in July 2022, we filed a shelf registration statement with the SEC that is effective for a term of three years and expires in July 2025. The amount of securities to be issued pursuant to the shelf registration statement filed in July 2022 was not specified when it was filed and there is no specific dollar limit on the amount of securities we may issue. The securities covered by the registration statement filed in July 2022 include: (i) Common Shares; (ii) preferred shares; (iii) debt securities; (iv) subscription rights; and (v) warrants. The specifics of any future offerings, along with the use of proceeds of any securities offered, will be described in detail in a prospectus supplement, or other offering materials, at the time of any offering.

As of March 31, 2024 and December 31, 2023, our debt consisted of asset based leverage facilities, a revolving credit facility, and unsecured note issuances. We may from time to time enter into additional credit facilities, increase the size of our existing credit facilities or issue further debt securities. Any such incurrence or issuance would be subject to prevailing market conditions, our liquidity requirements, contractual and regulatory restrictions and other factors. In accordance with the 1940 Act, with certain limited exceptions, we are only allowed to incur borrowings, issue debt securities or issue preferred stock, if immediately after the borrowing or issuance, the ratio of total assets (less total liabilities other than indebtedness) to total indebtedness plus preferred stock, is at least 150%. As of March 31, 2024 and December 31, 2023, we had an aggregate amount of $5,298.0 million and $4,937.9 million of senior securities outstanding, respectively, and our asset coverage ratio was 197.3% and 200.3%, respectively. We seek to carefully consider our unfunded commitments for the purpose of planning our ongoing financial leverage. Further, we maintain sufficient borrowing capacity within the 150% asset coverage limitation to cover any outstanding unfunded commitments we are required to fund. From time to time we may also repurchase our outstanding debt. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions, and other factors. The amounts involved in any such purchase transactions, individually or in the aggregate, may be material.

Cash and cash equivalents as of March 31, 2024, taken together with our $1,302.0 million of unused capacity under our credit facilities (subject to borrowing base availability, $1,302.0 million is available to borrow) is expected to be sufficient for our investing activities and to conduct our operations in the near term. Additionally, we held $108.8 million of Level 2 debt investments as of March 31, 2024, which could provide additional liquidity if necessary.

Although we have historically been able to obtain sufficient borrowing capacity, a deterioration in economic conditions or any other negative economic developments could restrict our access to financing in the future. We may not be able to find new financing for future investments or liquidity needs and, even if we are able to obtain such financing, such financing may not be on as favorable terms as we have previously obtained. These factors may limit our ability to make new investments and adversely impact our results of operations.

As of March 31, 2024, we had $147.7 million in cash and cash equivalents. During the three months ended March 31, 2024, cash used in operating activities was $395.5 million, primarily due to purchases of investments of $719.1 million partially offset by sales of investments and principal repayments of $186.7 million and receipt of interest payments from our investments. Cash provided by financing activities was $388.3 million during the period, which was primarily as a result of borrowings on our credit facilities and Unsecured Notes of $363.8 million and $162.0 million of proceeds from the issuance of our Common Shares partially offset by dividends paid in cash of $137.4 million.

Our liquidity and capital resources are generated primarily from cash flows from interest, dividends and fees earned from our investments and principal repayments, our credit facilities, debt securitization transactions, and other secured and unsecured debt.

From time to time we may also repurchase our outstanding debt. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions, and other factors. The amounts involved in any such purchase transactions, individually or in the aggregate, may be material.

Cash and cash equivalents as of March 31, 2024, taken together with our $1,302.0 million of unused capacity under our credit facilities (subject to borrowing base availability, $1,302.0 million is available to borrow) is expected to be sufficient for our investing activities and to conduct our operations in the near term. Additionally, we held $108.8 million of Level 2 debt investments as of March 31, 2024, which could provide additional liquidity if necessary.

Although we have historically been able to obtain sufficient borrowing capacity, a deterioration in economic conditions or any other negative economic developments could restrict our access to financing in the future. We may not be able to find new financing for future investments or liquidity needs and, even if we are able to obtain such financing, such financing may not be on as favorable terms as we have previously obtained. These factors may limit our ability to make new investments and adversely impact our results of operations.

As of March 31, 2024, we had $147.7 million in cash and cash equivalents. During the three months ended March 31, 2024, cash used in operating activities was $395.5 million, primarily due to purchases of investments of $719.1 million partially offset by sales of investments and principal repayments of $186.7 million and receipt of interest payments from our investments. Cash provided by financing activities was $388.3 million during the period, which was primarily as a result of borrowings on our credit facilities and Unsecured Notes of $363.8 million and $162.0 million of proceeds from the issuance of our Common Shares partially offset by dividends paid in cash of $137.4 million.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Uncertainty with respect to the economic conditions has introduced significant volatility in the financial markets, and the effect of the volatility could materially impact our market risks. We are subject to financial market risks, including valuation risk and interest rate risk. Our exposure to market risk has not materially changed from what was previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Effects of Leverage [Text Block]

Financial Condition, Liquidity and Capital Resources

Our liquidity and capital resources are generated primarily from cash flows from interest, dividends and fees earned from our investments and principal repayments, our credit facilities, debt securitization transactions, and other secured and unsecured debt. We may also generate cash flow from operations, future borrowings and future offerings of securities including public and/or private issuances of debt and/or equity securities through both registered offerings and private offerings. The primary uses of our cash and cash equivalents are for (i) originating loans and purchasing senior secured debt investments, (ii) funding the costs of our operations (including fees paid to our Adviser and expense reimbursements paid to our Administrator), (iii) debt service, repayment and other financing costs of our borrowings and (iv) cash distributions to the holders of our shares.

To facilitate public issuances of debt and/or equity securities, in July 2022, we filed a shelf registration statement with the SEC that is effective for a term of three years and expires in July 2025. The amount of securities to be issued pursuant to the shelf registration statement filed in July 2022 was not specified when it was filed and there is no specific dollar limit on the amount of securities we may issue. The securities covered by the registration statement filed in July 2022 include: (i) Common Shares; (ii) preferred shares; (iii) debt securities; (iv) subscription rights; and (v) warrants. The specifics of any future offerings, along with the use of proceeds of any securities offered, will be described in detail in a prospectus supplement, or other offering materials, at the time of any offering.

As of March 31, 2024 and December 31, 2023, our debt consisted of asset based leverage facilities, a revolving credit facility, and unsecured note issuances. We may from time to time enter into additional credit facilities, increase the size of our existing credit facilities or issue further debt securities. Any such incurrence or issuance would be subject to prevailing market conditions, our liquidity requirements, contractual and regulatory restrictions and other factors. In accordance with the 1940 Act, with certain limited exceptions, we are only allowed to incur borrowings, issue debt securities or issue preferred stock, if immediately after the borrowing or issuance, the ratio of total assets (less total liabilities other than indebtedness) to total indebtedness plus preferred stock, is at least 150%. As of March 31, 2024 and December 31, 2023, we had an aggregate amount of $5,298.0 million and $4,937.9 million of senior securities outstanding, respectively, and our asset coverage ratio was 197.3% and 200.3%, respectively. We seek to carefully consider our unfunded commitments for the purpose of planning our ongoing financial leverage. Further, we maintain sufficient borrowing capacity within the 150% asset coverage limitation to cover any outstanding unfunded commitments we are required to fund. From time to time we may also repurchase our outstanding debt.

Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2024

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The condensed consolidated financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States (“GAAP”). As an investment company, the Company applies the accounting and reporting guidance in Accounting Standards Codification (“ASC”) Topic 946, “Financial Services – Investment Companies” (“ASC 946”) issued by the Financial Accounting Standards Board (“FASB”).

The interim condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 6 and Article 10 of Regulation S-X. Accordingly, certain disclosures accompanying the annual consolidated financial statements prepared in accordance with GAAP are omitted. In the opinion of management, all adjustments considered necessary for the fair presentation of the condensed consolidated financial statements for the interim period presented, have been included. The current period’s results of operations will not necessarily be indicative of results that ultimately may be achieved for the fiscal year ending December 31, 2024.

All intercompany balances and transactions have been eliminated.

Certain prior period information has been reclassified to conform to the current period presentation.

Use of Estimates

Use of Estimates

The preparation of condensed 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 condensed consolidated financial statements. Such amounts could differ from those estimates and such differences could be material. Assumptions and estimates regarding the valuation of investments involve a higher degree of judgment and complexity and these assumptions and estimates may be significant to the condensed consolidated financial statements. Actual results may ultimately differ from those estimates.

Consolidation

Consolidation

As provided under ASC 946, the Company will 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.

The Company consolidated the results of the Company’s wholly-owned subsidiaries which are considered to be investment companies. As of March 31, 2024 and December 31, 2023, the Company's consolidated subsidiaries were BGSL Jackson Hole Funding LLC (“Jackson Hole Funding”), BGSL Breckenridge Funding LLC (“Breckenridge Funding”), BGSL Big Sky Funding LLC (“Big Sky Funding”), BGSL Investments LLC (“BGSL Investments”), BXSL Associates GP (Lux) S.à r.l, BXSL Direct Lending (Lux) SCSp, BXSL C-1 LLC, and BXSL C-2 Funding LLC.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents consist of demand deposits and highly liquid investments, such as money market funds, with original maturities of three months or less. Cash and cash equivalents are carried at cost, which approximates fair value. The Company deposits its cash and cash equivalents with financial institutions and, at times, may exceed the Federal Deposit Insurance Corporation insured limit.

Investments/Receivables/Payables From Investments Sold/Purchased

Investments

Investment transactions are recorded on a trade date basis.

Realized gains or losses are measured by the difference between the net proceeds received (excluding prepayment fees, if any) and the amortized cost basis of the investment using the specific identification method without regard to unrealized gains or losses previously recognized, and include investments charged off during the period, net of recoveries, and is recorded within Net realized gain (loss) on the Condensed Consolidated Statements of Operations.

The net change in unrealized gains or losses primarily reflects the change in investment values, including the reversal of previously recorded unrealized gains or losses with respect to investments realized during the period, and is recorded within Net change in unrealized appreciation (depreciation) on the Condensed Consolidated Statements of Operations.

Valuation of Investments

The Company is required to report its investments, including those for which current market values are not readily available, at fair value.

The Company values its investments in accordance with ASC 820, Fair Value Measurements (“ASC 820”), which defines fair value as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the applicable measurement date, and Rule 2a-5 under the 1940 Act.

Under ASC 820, fair value is based on observable market prices or parameters or derived from such prices or parameters when such quotations are readily available. In accordance with Rule 2a-5 under the 1940 Act, fair value means the value of a portfolio investment for which market quotations are not readily available. A market quotation is “readily available” only when it is a quoted price (unadjusted) in active markets for identical instruments that a fund can access at the measurement date, provided that such a quotation is not considered to be readily available if it is not reliable.

Where prices or inputs are not available or, in the judgment of the Board, with assistance of the Adviser, the Audit Committee and independent valuation firm(s), determine to be not reliable, valuation techniques based on the facts and circumstances of the particular investment will be utilized. These valuation approaches involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the investments or market and the investments’ complexity. In the absence of observable, reliable market prices, the Company values its investments using various valuation methodologies applied on a consistent basis.

An enterprise value (“EV”) analysis is generally performed to determine the value of equity investments, control debt investments and non-control debt investments that are credit-impaired, and to determine if debt investments are credit-impaired. The Adviser will generally utilize approaches including the market approach, the income approach or both approaches, as appropriate, when calculating EV. The primary method for determining EV for non-control investments, and control investments without reliable projections, uses a multiple analysis whereby appropriate multiples are applied to the portfolio company’s earnings before interest, taxes, depreciation and amortization (“EBITDA”) or another key financial metric (e.g., such as revenues, cash flows or net income) (“Performance Multiple”). Performance Multiples are typically determined based upon a review of publicly-traded comparable companies and market comparable transactions, if any. The second method for determining EV (and primary method for control investments with reliable projections) uses a discounted cash flow analysis whereby future expected cash flows and the anticipated terminal value of the portfolio company are discounted to determine a present value using estimated discount rates. The income approach is generally used when the Adviser has visibility into the long term projected cash flows of a portfolio company.

If debt investments are credit-impaired, which occurs when there is insufficient coverage under the enterprise value analysis through the respective investment’s position in the capital structure, the Adviser generally uses the enterprise value “waterfall” approach or a recovery method (if a liquidation or restructuring is deemed likely) to determine fair value. For debt investments that are not determined to be credit-impaired, the Adviser generally uses a market interest rate yield analysis to determine fair value. To determine fair value using a yield analysis, the expected cash flows are projected based on the contractual terms of the debt security and discounted back to the measurement date based on a market yield. A market yield is determined based upon an assessment of current and expected market yields for similar investments and risk profiles. The Company considers the current contractual interest rate, the maturity and other terms of the investment relative to risk of the company and the specific investment. A key determinant of risk, among other things, is the leverage through the investment relative to the enterprise value of the portfolio company. As debt investments held by the Company are substantially illiquid with no active transaction market, the Company depends on primary market data, including newly funded transactions, as well as secondary market data with respect to high yield debt instruments and syndicated loans, as inputs in determining the appropriate market yield, as applicable. The fair value of loans with call protection is generally capped at par plus applicable prepayment premium in effect at the measurement date.

ASC 820 prioritizes the use of observable market prices derived from such prices. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The levels used for classifying investments are not necessarily an indication of the risk associated with investing in these securities. The three levels of the fair value hierarchy are as follows:

•Level 1: Inputs to the valuation methodology are quoted prices available in active markets for identical instruments as of the reporting date. The types of financial instruments included in Level 1 include unrestricted securities, including equities and derivatives, listed in active markets.

•Level 2: Inputs to the valuation methodology are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date. The types of financial instruments in this category include less liquid and restricted securities listed in active markets, securities traded in other than active markets, government and agency securities and certain over-the-counter derivatives where the fair value is based on observable inputs.

•Level 3: Inputs to the valuation methodology are unobservable and significant to overall fair value measurement. The inputs into the determination of fair value require significant management judgment or estimation. Financial instruments that are included in this category include debt and equity investments in privately held entities, collateralized loan obligations (“CLOs”) and certain over-the-counter derivatives where the fair value is based on unobservable inputs.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the overall fair value measurement. The Board’s assessment, with the assistance of the Adviser, the Audit Committee and independent valuation firm(s), of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment. Transfers between levels, if any, are recognized at the beginning of the quarter in which the transfer occurs.

The Company evaluates the source of the inputs, including any markets in which its investments are trading (or any markets in which securities with similar attributes are trading), in determining fair value. When an investment is valued based on prices provided by reputable dealers or pricing services (that is, broker quotes), the Company subjects those prices to various criteria in making the determination as to whether a particular investment would qualify for treatment as a Level 2 or Level 3 investment.

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 Company’s investments may fluctuate from period to period, and these differences could be material. Additionally, the fair value of the Company’s investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that the Company may ultimately realize. Further, such investments are generally subject to legal and other restrictions on resale or otherwise are less liquid than publicly-traded securities. If the Company was required to liquidate a portfolio investment in a forced or liquidation sale, it could realize significantly less than the value at which the Company has recorded it. In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the unrealized gains or losses reflected in the valuations currently assigned. See “Item 2. Management’s Discussion and Analysis of Financial Conditions and Results of Operations—Critical Accounting Estimates.”

Receivables/Payables From Investments Sold/Purchased

Receivables/payables from investments sold/purchased consist of amounts receivable to or payable by the Company for transactions that have not settled at the reporting date.

Derivative Instruments/Forward Purchase Agreement

Derivative Instruments

The Company recognizes all derivative instruments as assets or liabilities at fair value in its condensed consolidated financial statements. Derivative contracts entered into by the Company are not designated in hedge accounting relationships and all changes in fair value are recognized through current period gains or losses.

In the normal course of business, the Company has commitments and risks resulting from its investment transactions, which may include those involving derivative instruments. Derivative instruments are measured in terms of the notional contract amount and derive their value based upon one or more underlying instruments. While the notional amount gives some indication of the Company’s derivative activity, it generally is not exchanged, but is only used as the basis on which interest and other payments are exchanged. Derivative instruments are subject to various risks similar to non-derivative instruments including market, credit, liquidity, and operational risks. The Company manages these risks on an aggregate basis as part of its risk management process.

Forward Purchase Agreement

Forward purchase agreements are recognized at fair value through current period gains or losses on the date on which the contract is entered into and are subsequently re-measured at fair value. All forward purchase agreements are carried as assets when fair value is positive and as liabilities when fair value is negative. A forward purchase agreement is derecognized when the obligation specified in the contract is discharged, canceled or expired.

Foreign Currency Transactions

Foreign Currency Transactions

Amounts denominated in foreign currencies are translated into U.S. dollars on the following basis: (i) investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates effective on the last business day of the period; and (ii) purchases and sales of investments, borrowings and repayments of such borrowings, income, and expenses denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates prevailing on the transaction dates.

The Company includes net changes in fair values on investments held resulting from foreign exchange rate fluctuations in Translation of assets and liabilities in foreign currencies on the Condensed Consolidated Statements of Operations, if any. Foreign security and currency translations may involve certain considerations and risks not typically associated with investing in U.S. companies and U.S. government securities. 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.

Revenue Recognition

Revenue Recognition

Interest Income

Interest income is recorded on an accrual basis and includes the accretion of discounts and amortizations of premiums. Discounts from and premiums to par value on debt investments purchased are accreted/amortized into interest income over the life of the respective security using the effective interest method. The amortized cost of debt investments represents the original cost, including loan origination fees and upfront fees received that are deemed to be an adjustment to yield, adjusted for the accretion of discounts and amortization of premiums, if any. Upon prepayment of a loan or debt security, any prepayment premiums, unamortized upfront loan origination fees and unamortized discounts are recorded as interest income in the current period. For the three months ended March 31, 2024 and 2023, the Company recorded $1.9 million and $0.4 million, respectively, in non-recurring interest income (e.g., prepayment premiums, accelerated accretion of upfront loan origination fees and unamortized discounts).

PIK Income

The Company has loans in its portfolio that contain payment-in-kind (“PIK”) provisions. PIK represents interest that is accrued and recorded as interest income at the contractual rates, increases the loan principal on the respective capitalization dates, and is generally due at maturity. Such income is included in payment-in-kind interest income in the Condensed Consolidated Statements of Operations. If at any point the Company believes PIK is not expected to be realized, the investment generating PIK will be placed on non-accrual status. When a PIK investment is placed on non-accrual status, the accrued, uncapitalized interest is generally reversed through payment-in-kind interest income. To satisfy the Company’s annual RIC distribution requirements, this non-cash source of income must be included in determining the amounts to be paid out to shareholders in the form of dividends, even though the Company has not yet collected cash.

Dividend Income

Dividend income on preferred equity securities is recorded on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. 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.

Fee Income

The Company may receive various fees in the ordinary course of business such as structuring, consent, waiver, amendment, syndication and other miscellaneous fees as well as fees for managerial assistance rendered by the Company to the portfolio companies. Such fees are recognized as income when earned or the services are rendered.

Non-Accrual Income

Loans are generally placed on non-accrual status when there is reasonable doubt whether principal or interest will be collected in full. Accrued interest is generally reversed when a loan is placed on non-accrual status. Additionally, any original issue discount and market discount are no longer accreted to interest income as of the date the loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. Non-accrual loans are restored to accrual status when past due principal and interest is paid current and, in management’s judgment, are likely to remain current. Management may make exceptions to this treatment and determine to not place a loan on non-accrual status if the loan has sufficient collateral value and is in the process of collection.

For further information regarding the non-accrual status of investments refer to “Note 4. Investments”.

Organization Expenses and Offering Expenses

Organization Expenses and Offering Expenses

The Company records expenses related to public equity offerings as a reduction of capital upon completion of an offering of registered securities. The costs associated with any renewals of a shelf registration statement will be expensed as incurred.

Deferred Financing Costs and Debt Issuance Costs

Deferred Financing Costs and Debt Issuance Costs

Deferred financing and debt issuance costs represent fees and other direct incremental costs incurred in connection with the Company’s borrowings. These expenses are deferred and amortized into interest expense over the life of the related debt instrument. Deferred financing costs related to revolving credit facilities are presented separately as an asset on the Company’s Condensed Consolidated Statements of Assets and Liabilities. Debt issuance costs related to any issuance of installment debt or notes are presented net against the outstanding debt balance of the related security.

Income Taxes

Income Taxes

The Company has elected to be treated as a BDC under the 1940 Act. The Company also has elected to be treated as a RIC under the Code. So long as the Company maintains its status as a RIC, it generally will not pay corporate-level U.S. federal income taxes on any ordinary income or capital gains that it distributes at least annually to its shareholders as dividends. Rather, any tax liability related to income earned and distributed by the Company would represent obligations of the Company’s investors and would not be reflected in the condensed consolidated financial statements of the Company.

The Company evaluates tax positions taken or expected to be taken in the course of preparing its condensed consolidated financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are reserved and recorded as a tax benefit or expense in the current year. All penalties and interest associated with income taxes are included in income tax expense. Conclusions regarding tax positions are subject to review and may be adjusted at a later date based on factors including, but not limited to, on-going analyses of tax laws, regulations and interpretations thereof.

To qualify for and maintain qualification as a RIC, the Company must, among other things, meet certain source-of-income and asset diversification requirements. In addition, to qualify for taxation as a RIC, the Company must distribute to its shareholders, for each taxable year, at least 90% of the sum of (i) its “investment company taxable income” for that year (without regard to the deduction for dividends paid), which is generally its ordinary income plus the excess, if any, of its realized net short-term capital gains over its realized net long-term capital losses and (ii) its net tax-exempt income.

In addition, based on the excise tax distribution requirements, the Company is subject to a 4% nondeductible federal excise tax on certain undistributed income unless the Company distributes in a timely manner in each taxable year an amount at least equal to the sum of (i) 98% of its ordinary income for the calendar year, (ii) 98.2% of its capital gain net income (both long-term and short-term) for the one-year period ending October 31 in that calendar year and (iii) any income realized, but not distributed, in prior years. For this purpose, however, any ordinary income or capital gain net income retained by the Company that is subject to corporate income tax is considered to have been distributed.

Distributions

Distributions

To the extent that the Company has taxable income available, the Company intends to make quarterly distributions to its shareholders. Distributions to shareholders are recorded on the record date. All distributions will be paid at the discretion of the Board and will depend on the Company’s earnings, financial condition, maintenance of the Company's tax treatment as a RIC, compliance with applicable BDC regulations and such other factors as the Board may deem relevant from time to time.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In June 2022, the FASB issued Accounting Standards Update (“ASU”) 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions” (“ASU 2022-03”), which clarifies guidance for fair value measurement of an equity security subject to a contractual sale restriction and establishes new disclosure requirements for such equity securities. ASU 2022-03 is effective for fiscal years beginning after December 15, 2023 and for interim periods within those fiscal years, and has been adopted by the Company beginning with the condensed consolidated financial statements as of and for the three months ended March 31, 2024. The adoption of this guidance did not have a material impact on the Company’s condensed consolidated financial statements.

In November 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” (“ASU 2023-07”). ASU 2023-07 enhances the disclosures required for reportable segments on an annual and interim basis. ASU 2023-07 is effective on a retrospective basis for annual periods beginning after December 15, 2023, for interim periods within fiscal years beginning after December 15, 2024, and early adoption is permitted. The Company does not expect the adoption of ASU 2023-07 to have a material impact on its consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” (“ASU 2023-09”). ASU 2023-09 requires additional disaggregated disclosures on the entity’s effective tax rate reconciliation and additional details on income taxes paid. ASU 2023-09 is effective on a prospective basis, with the option for retrospective application, for annual periods beginning after December 15, 2024 and early adoption is permitted. The Company does not expect the adoption of ASU 2023-09 to have a material impact on its consolidated financial statements.

Fair Value Measurements

The significant unobservable input used in the yield analysis is the discount rate based on comparable market yields. The significant unobservable input used for market quotations are broker quoted prices provided by independent pricing services. The significant unobservable input used under the market approach is the Performance Multiple. Significant increases in discount rates would result in a significantly lower fair value measurement. Significant decreases in quoted prices or Performance Multiples would result in a significantly lower fair value measurement.
