BLACKSTONE SECURED LENDING FUND

  % Notes due    

We are offering $     in aggregate principal amount of     % notes due     , which we refer to as the Notes. The Notes will mature on     ,     . We will pay interest on the Notes on    and    of each year, beginning on     , 2024. We may redeem the Notes in whole or in part at any time or from time to time at the redemption price discussed under the caption “Description of Notes — Optional Redemption” in this prospectus supplement. In addition, holders of the Notes can require us to repurchase the Notes at 100% of their principal amount upon the occurrence of a Change of Control Repurchase Event (as defined herein). The Notes will be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The Notes will be our direct, general unsecured obligations and rank pari passu, or equal, with all existing and future unsecured unsubordinated indebtedness issued by us, but will rank senior to our future indebtedness that is expressly subordinated in right of payment to the Notes. We are a specialty finance company that has elected to be regulated as a business development company under the Investment Company Act of 1940. We seek to generate current income primarily through direct originations of senior secured loans and, to a lesser extent, originations of mezzanine and unsecured loans and investments in corporate bonds and equity securities.

Blackstone Secured Lending Fund (together with its consolidated subsidiaries, the “Company”) is a Delaware statutory trust formed on March 26, 2018, and is structured as an externally managed, non-diversified, closed-end management investment company. The Company has 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 under Subchapter M of the Internal Revenue Code of 1986, as amended (together with the rules and regulations promulgated thereunder, the “Code”).

We are 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.

Our investment objectives are to generate current income and, to a lesser extent, long-term capital appreciation. We believe that Blackstone’s investment platform provides us with a competitive advantage in selecting investments, and to achieve our investment objectives, we will leverage the Adviser’s investment team’s and Blackstone’s extensive network of relationships with other sophisticated institutions to source, evaluate and, as appropriate, partner with on transactions. There are no assurances that we will achieve our investment objectives.

Investing in the Notes involves risks, including the risk of leverage, that are described in the “Risk Factors ” section beginning on page S-11 of this prospectus supplement and page 29 of the accompanying prospectus and the matters discussed in the documents incorporated or deemed to be incorporated by reference in this prospectus supplement and the accompanying prospectus.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Information included or incorporated by reference in this prospectus supplement and the accompanying prospectus 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:

S-2

Table of Contents

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 prospectus supplement should not be regarded as a representation by us that our plans and objectives will be achieved. The factors listed under “Risk Factors” in our annual report on Form 10-K for the year ended December 31, 2023, as amended or supplemented in any subsequent filings with the SEC, which are incorporated by reference in this prospectus supplement, as well as any cautionary language included or incorporated by reference in this prospectus supplement and the accompanying prospectus provide examples of risks, uncertainties and events that may cause our actual results to differ materially from the expectations we describe in our forward-looking statements. The occurrence of the events described in these risk factors and elsewhere in this prospectus supplement or the accompanying prospectus could have a material adverse effect on our business, results of operations and financial position. These forward-looking statements apply only as of the date of this prospectus supplement or the accompanying prospectus, and we assume no obligation to update any such forward-looking statements except as required by 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 will file with the SEC including registration statements on Form N-2, annual reports on Form 10-K, 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 prospectus supplement are excluded from the safe harbor protection provided by Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

RISK FACTORS

Investing in our securities involves a number of significant risks. Before deciding whether to invest in the Notes, you should carefully consider the risks and uncertainties described in the section titled “Risk Factors” in our annual report on Form 10-K for the year ended December 31, 2023, as well as in subsequent filings with the SEC, which are incorporated by reference into this prospectus supplement and the accompanying prospectus, in their entirety, together with other information in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein. The risks described in these documents are not the only ones we face. Additional risks and uncertainties not presently known to us or not presently deemed material by us might also impair our operations and performance. The Notes will not be an appropriate investment for you if you are not knowledgeable about significant features of the Notes or financial matters in general. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks occur, our business, financial condition and results of operations could be materially and adversely affected. In such case, our net asset value, the trading price of our common shares and the value of our other securities could decline, and you may lose all or part of your investment. Please also read carefully the section titled “Cautionary Statement Regarding Forward-Looking Statements” in this prospectus supplement.

Risks Related to This Offering

The Notes are unsecured and therefore are effectively subordinated to any secured indebtedness we have incurred or may incur in the future.

The Notes are not secured by any of our assets or any of the assets of our subsidiaries. As a result, the Notes are effectively subordinated, or junior, to any secured indebtedness or other obligations we or our subsidiaries have incurred and may incur in the future (or any indebtedness that is initially unsecured that we later secure) to the extent of the value of the assets securing such indebtedness. In any liquidation, dissolution, bankruptcy or other similar proceeding, the holders of any of our existing or future secured indebtedness and the secured indebtedness of our subsidiaries may assert rights against the assets pledged to secure that indebtedness in order to receive full payment of their indebtedness before the assets may be used to pay other creditors, including the holders of the Notes. As of March 31, 2024, we had $0.8 billion aggregate principal amount of outstanding indebtedness under our senior secured revolving credit facility (the “Revolving Credit Facility”). The Revolving Credit Facility is secured by a perfected first-priority security interest in substantially all the portfolio investments held by us and each guarantor party thereto; the indebtedness thereunder is therefore effectively senior to the Notes to the extent of the value of such assets.

The Notes are structurally subordinated to the indebtedness and other liabilities of our subsidiaries.

The Notes are obligations exclusively of the Company and not of any of our subsidiaries. None of our subsidiaries is a guarantor of the Notes and the Notes are not required to be guaranteed by any subsidiaries we may acquire or create in the future. As of March 31, 2024, approximately $1.7 billion of the indebtedness, at par value, required to be consolidated on our balance sheet was held through subsidiary financing vehicles and secured by certain assets of such subsidiaries. Except to the extent we are a creditor with recognized claims against our subsidiaries, all claims of creditors (including trade creditors) and holders of preferred stock, if any, of our subsidiaries will have priority over our equity interests in such subsidiaries (and therefore the claims of our creditors, including holders of the Notes) with respect to the assets of such subsidiaries. Even if we are recognized as a creditor of one or more of our subsidiaries, our claims would still be effectively subordinated to any security interests in the assets of any such subsidiary and to any indebtedness or other liabilities of any such subsidiary senior to our claims. Consequently, the Notes are structurally subordinated, or junior, to all existing and future indebtedness and other obligations (including trade payables) incurred by any of our subsidiaries, financing vehicles or similar facilities and any subsidiaries, financing vehicles or similar facilities that we may in the future acquire or establish. Our subsidiaries may incur substantial additional indebtedness in the future, all of which would be structurally senior to the Notes.

S-11

Table of Contents

Our amount of debt outstanding may increase as a result of this offering. Our current indebtedness could adversely affect our business, financial condition and results of operations and our ability to meet our payment obligations under the Notes and our other debt.

As of March 31, 2024, our total consolidated indebtedness, at par, was approximately $5.3 billion, $2.5 billion of which was secured (of which $1.7 billion was indebtedness of our subsidiaries) and $2.8 billion of which was unsecured. See “Capitalization.”

The use of debt could have significant consequences on our future operations, including:

Any of the above-listed factors could have an adverse effect on our business, financial condition and results of operations and our ability to meet our payment obligations under the Notes and our other debt.

Our ability to meet our payment and other obligations under our debt agreements depends on our ability to generate significant cash flow in the future. This, to some extent, is subject to general economic, financial, competitive, legislative and regulatory factors as well as other factors that are beyond our control.

We cannot assure you that our business will generate sufficient cash flow from operations or that future borrowings will be available to us under our Revolving Credit Facility or otherwise in an amount sufficient to enable us to pay our indebtedness, including the Notes, or to fund our other liquidity needs. We may need to refinance all or a portion of our indebtedness, including the Notes, on or before it matures. We cannot assure you that we will be able to refinance any of our indebtedness on commercially reasonable terms or at all. If we cannot service our indebtedness, we may have to take actions such as selling assets or seeking additional equity. We cannot assure you that any such actions, if necessary, could be effected on commercially reasonable terms or at all, or on terms that would not be disadvantageous to our shareholders or on terms that would not require us to breach the terms and conditions of our existing or future debt agreements, including our payment obligations under the Notes.

A downgrade, suspension or withdrawal of the credit rating assigned by a rating agency to us or the Notes, if any, or change in the debt markets could cause the liquidity or market value of the Notes to decline significantly.

Our credit ratings are an assessment by rating agencies of our ability to pay our debts when due. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the Notes. These credit ratings may not reflect the potential impact of risks relating to the structure or marketing of the Notes. Credit ratings are not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any time by the issuing organization in its sole discretion. Neither we nor any underwriter undertakes any obligation to maintain our credit ratings or to advise holders of Notes of any changes in our credit

ratings. The Notes are rated by Moody’s Investor Service, or Moody’s, S&P Global Ratings, or S&P, and Fitch Ratings, or Fitch. There can be no assurance that their respective credit ratings will remain for any given period

S-12

Table of Contents

of time or that such credit ratings will not be lowered or withdrawn entirely by Moody’s, S&P or Fitch if in any of their respective judgments future circumstances relating to the basis of the credit rating, such as adverse changes in our company, so warrant. The conditions of the financial markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future.

An increase in market interest rates could result in a decrease in the market value of the Notes.

The condition of the financial markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future, which could have an adverse effect on the market prices of the Notes. In general, as market interest rates rise, debt securities bearing interest at fixed rates of interest decline in value. Consequently, if you purchase Notes bearing interest at fixed rates and market interest rates increase, the market values of those Notes may decline. We cannot predict the future level of market interest rates.

The indenture governing the Notes contains limited protection for holders of the Notes.

The indenture governing the Notes offers limited protection to holders of the Notes. The terms of the indenture and the Notes do not restrict our or any of our subsidiaries’ ability to engage in, or otherwise be a party to, a variety of corporate transactions, circumstances or events that could have an adverse impact on your investment in the Notes. In particular, the terms of the indenture and the Notes do not place any restrictions on our or our subsidiaries’ ability to:

Furthermore, the terms of the indenture and the Notes do not protect holders of the Notes in the event that we experience changes (including significant adverse changes) in our financial condition, results of operations or credit ratings, as they do not require that we or our subsidiaries adhere to any financial tests or ratios or specified levels of net worth, revenues, income, cash flow or liquidity.

S-13

Table of Contents

Our ability to recapitalize, incur additional debt and take a number of other actions that are not limited by the terms of the Notes may have important consequences for you as a holder of the Notes, including making it more difficult for us to satisfy our obligations with respect to the Notes or negatively affecting the trading value of the Notes.

Certain of our current debt instruments include more protections for their holders than the indenture and the Notes. In addition, other debt we issue or incur in the future could contain more protections for its holders than the indenture and the Notes, including additional covenants and events of default. The issuance or incurrence of any such debt with incremental protections could affect the market for and trading levels and prices of the Notes.

The optional redemption provision may materially adversely affect your return on the Notes.

The Notes are redeemable in whole or in part upon certain conditions at any time or from time to time at our option. We may choose to redeem the Notes at times when prevailing interest rates are lower than the interest rate paid on the Notes. In this circumstance, you may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as that of the Notes being redeemed.

If we default on our obligations to pay our other indebtedness, we may not be able to make payments on the Notes.

Any default under the agreements governing our indebtedness, including a default under our Revolving Credit Facility or under the Existing Unsecured Notes, or under other indebtedness to which we may be a party, that is not waived by the required lenders or holders and the remedies sought by the holders of such indebtedness could make us unable to pay principal, premium, if any, and interest on the Notes and substantially decrease the market value of the Notes.

If we are unable to generate sufficient cash flow and are otherwise unable to obtain funds necessary to meet required payments of principal, premium, if any, and interest on our indebtedness, or if we otherwise fail to comply with the various covenants, including financial and operating covenants, in the instruments governing our indebtedness, we could be in default under the terms of the agreements governing such indebtedness. In the event of such default, the holders of such indebtedness could elect to declare all the funds borrowed thereunder to be due and payable, together with accrued and unpaid interest, the lenders under our Revolving Credit Facility or other debt we may incur in the future could elect to terminate their commitments, cease making further loans and institute foreclosure proceedings against our assets, and we could be forced into bankruptcy or liquidation.

If our operating performance declines, we may in the future need to seek to obtain waivers from the required lenders or holders under the agreements governing our indebtedness, or other indebtedness that we may incur in the future, to avoid being in default. If we breach our covenants under the agreements governing our indebtedness and seek a waiver, we may not be able to obtain a waiver from the required lenders or holders. If this occurs, we would be in default and our lenders or debt holders could exercise their rights as described above, and we could be forced into bankruptcy or liquidation.

If we are unable to repay debt, lenders having secured obligations, including the lenders under our Revolving Credit Facility, could proceed against the collateral securing the debt. Because our Revolving Credit Facility and Existing Unsecured Notes have, the indenture will have, and any future debt will likely have, customary cross-default provisions, if the indebtedness thereunder, hereunder or under any future credit facility is accelerated, we may be unable to repay or finance the amounts due. See “Description of Notes” in this prospectus supplement and “Description of Our Debt Securities” in the accompanying prospectus.

We may not be able to repurchase the Notes upon a Change of Control Repurchase Event.

We may not be able to repurchase the Notes upon a Change of Control Repurchase Event because we may not have sufficient funds. Upon the occurrence of a Change of Control Repurchase Event, as defined in the indenture that governs the Notes, as supplemented, subject to certain conditions, we will be required to offer to

S-14

Table of Contents

repurchase all outstanding Notes at 100% of their principal amount, plus accrued and unpaid interest. The source of funds for that purchase of Notes will be our available cash or cash generated from our operations or other potential sources, including borrowings, investment repayments, sales of assets or sales of equity. We cannot assure you that sufficient funds from such sources will be available at the time of any Change of Control Repurchase Event to make required repurchases of Notes tendered. The terms of the Revolving Credit Facility provide that certain change of control events will constitute an event of default thereunder entitling the lenders to accelerate any indebtedness outstanding under the credit facility at that time and to terminate the credit facility. In addition, the indentures governing our Existing Unsecured Notes each contain a provision that would require us to offer to purchase the respective Existing Unsecured Notes upon the occurrence of a fundamental change.

Any failure to comply with these provisions would constitute an event of default under each of the other agreements governing our indebtedness, including the indenture. Our future debt instruments also may contain similar restrictions and provisions. If the holders of the Notes exercise their right to require us to repurchase all the Notes upon a Change of Control Repurchase Event, the financial effect of this repurchase could cause a default under our future debt instruments, even if the Change of Control Repurchase Event itself would not cause a default. It is possible that we will not have sufficient funds at the time of the Change of Control Repurchase Event to make the required repurchase of the Notes or our other debt. See “Description of Notes — Offer to Repurchase Upon a Change of Control Repurchase Event.”

We cannot assure that an active trading market will be maintained for the Notes.

The Notes are a new issue of debt securities and there currently is no trading market for the Notes. We do not intend to apply for listing of the Notes on any securities exchange or for quotation of the Notes on any automated dealer quotation system. If no active trading market develops, you may not be able to resell your Notes at their fair market value or at all. If the Notes are traded after their initial issuance, they may trade at a discount from their initial offering price depending on prevailing interest rates, the market for similar securities, our credit ratings, general economic conditions, our financial condition, performance and prospects and other factors. Certain of the underwriters have advised us that they currently intend to make a market in the Notes but they are not obligated to do so. The underwriters may discontinue any market-making in the Notes at any time at their sole discretion. In addition, any market-making activity will be subject to limits imposed by law. Accordingly, we cannot assure you that a liquid trading market will be maintained for the Notes, that you will be able to sell your Notes at a particular time or that the price you receive when you sell will be favorable. To the extent an active trading market is not maintained, the liquidity and trading price for the Notes may be harmed. Accordingly, you may be required to bear the financial risk of an investment in the Notes for an indefinite period of time.

USE OF PROCEEDS

We estimate that the net proceeds we will receive from the sale of $    million aggregate principal amount of Notes in this offering will be approximately $    million, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us.

We intend to use the net proceeds from this offering for general corporate purposes, which may include, among other things, investing in accordance with our investment objectives and strategies described in this prospectus supplement and the accompanying prospectus and repaying indebtedness (which will be subject to reborrowing). We may use a portion of net proceeds to repay amounts outstanding under our Revolving Credit Facility and/or the secured financing facilities of certain of our wholly-owned subsidiaries, which includes the Jackson Hole Funding Facility, the Breckenridge Funding Facility and the Big Sky Funding Facility (collectively, the “SPV Financing Facilities”). For the three months ended March 31, 2024, amounts outstanding under the Revolving Credit Facility and the SPV Financing Facilities bore a weighted average interest rate (including unused fees and accretion of net discounts on unsecured debt) of 7.54% and the weighted average all-in cost of debt (including unused fees, accretion of net discounts on unsecured debt, and amortization of deferred financing costs) was 7.84%. The Revolving Credit Facility matures on June 28, 2028 (other than with respect to the foreign currency commitments of certain lenders in the amount of $200 million which mature on June 28, 2027) pursuant to an amortization schedule and the SPV Financing Facilities (Jackson Hole Funding Facility, Breckenridge Funding Facility and Big Sky Funding Facility) mature on May 17, 2027, December 21, 2026 and September 30, 2026, respectively.

Affiliates of certain of the underwriters are lenders under the Revolving Credit Facility or the SPV Financing Facilities. Accordingly, affiliates of certain of the underwriters may receive more than 5% of the proceeds of this offering to the extent such proceeds are used to repay or repurchase outstanding indebtedness under the Revolving Credit Facility or the SPV Financing Facilities.

DESCRIPTION OF NOTES

The following is a description of particular terms of the Notes.

We will issue the Notes under the base indenture between us and U.S. Bank Trust Company, National Association, as trustee, dated as of July 15, 2020, as supplemented by the separate sixth supplemental indenture between us and the trustee, to be dated as of the settlement date for the Notes. As used in this section, all references to the indenture mean the base indenture as supplemented by the sixth supplemental indenture. The terms of the Notes include those expressly set forth in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended.

The following description is a summary of the material provisions of the Notes and the indenture and does not purport to be complete. This summary is subject to and is qualified by reference to all the provisions of the Notes and the indenture, including the definitions of certain terms used in the indenture. We urge you to read these documents because they, and not this description, define your rights as a holder of the Notes. You may request a copy of the indenture from us by making a written request to Blackstone Secured Lending Fund, 345 Park Avenue, 31st Floor New York, NY 10154 or by calling us at (212) 503-2100. In addition, the SEC maintains a website at www.sec.gov that contains information we file with the SEC, including the indenture.

For purposes of this description, references to “we,” “our” and “us” refer only to Blackstone Secured Lending Fund and not to any of its current or future subsidiaries and references to “subsidiaries” refer to our consolidated subsidiaries and exclude any investments held by Blackstone Secured Lending Fund in the ordinary course of business which are not, under GAAP, consolidated on the financial statements of Blackstone Secured Lending Fund and its subsidiaries. Such references also include entities that engage in investment activities in securities or other assets that are primarily controlled by the Company. The Company complies with the provisions of the 1940 Act governing investment policies, capital structure, and leverage on an aggregate basis with its subsidiaries, and it treats subsidiary debt as its own. The principal investment strategies of the subsidiaries are substantially similar to those of the Company. The Company and its subsidiaries comply with provisions of the 1940 Act relating to affiliated transactions and custody.

General

The Notes:

S-18

Table of Contents

The indenture does not limit the amount of debt that may be issued by us or our subsidiaries under the indenture or otherwise. The indenture does not contain any financial covenants and does not restrict us from paying dividends or distributions or issuing or repurchasing our other securities. Other than restrictions described under “— Offer to Repurchase Upon a Change of Control Repurchase Event” and “— Covenants — Merger, Consolidation or Sale of Assets” in this prospectus supplement, the indenture does not contain any covenants or other provisions designed to afford holders of the Notes protection in the event of a highly leveraged transaction involving us or in the event of a decline in our credit rating as the result of a takeover, recapitalization, highly leveraged transaction or similar restructuring involving us that could adversely affect such holders.

We may, without the consent of the holders, issue additional Notes under the indenture with the same terms (except for the issue date, public offering price, and, if applicable, the initial interest payment date) as the Notes offered hereby in an unlimited aggregate principal amount; provided that, if such additional Notes are not fungible with the Notes offered hereby (or any other tranche of additional Notes) for U.S. federal income tax purposes, then such additional Notes will have different CUSIP numbers from the Notes offered hereby (and any such other tranche of additional Notes).

We do not intend to list the Notes on any securities exchange or any automated dealer quotation system.

Payments on the Notes; Paying Agent and Registrar; Transfer and Exchange

We will pay the principal of, and interest on, the Notes in global form registered in the name of or held by DTC or its nominee in immediately available funds to DTC or its nominee, as the case may be, as the registered holder of such Global Note (as defined below).

Payment of principal (and premium, if any) and any such interest on the Notes will be made at the corporate trust office of the trustee in such coin or currency of the United States as at the time of payment is legal tender for payment of public and private debts; provided, however, that at our option payment of interest may be made by check mailed to the address of the person entitled thereto as such address will appear in the security register.

A holder of Notes may transfer or exchange Notes at the office of the security registrar in accordance with the indenture. The security registrar and the trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents. No service charge will be imposed by us, the trustee or the security registrar for any registration of transfer or exchange of Notes, but we may require a holder to pay a sum sufficient to cover any transfer tax or other similar governmental charge required by law or permitted by the indenture.

The registered holder of a Note will be treated as its owner for all purposes.

Interest

The Notes will bear cash interest at a rate of      % per year until maturity. Interest on the Notes will accrue from     , 2024. Interest on the Notes will be payable semi-annually in arrears on      and      of each year, beginning on     , 2024.

Interest on the Notes will be paid to the person in whose name a Note is registered at 5:00 p.m. New York City time, or the close of business, on      or     , as the case may be, immediately preceding the relevant interest payment date. Interest on the Notes will be computed on the basis of a 360-day year composed of twelve 30-day months.

If any interest payment date, redemption date, the maturity date or any earlier required repurchase date upon a Change of Control Repurchase Event (defined below) of a Note falls on a day that is not a business day, the required payment will be made on the next succeeding business day and no interest on such payment will accrue

As of March 31, 2024, our total consolidated indebtedness, at par, was approximately $5.3 billion, $2.5 billion of which was secured (of which $1.7 billion was indebtedness of our subsidiaries) and $2.8 billion of which was unsecured. See “Capitalization.”

In the event of our bankruptcy, liquidation, reorganization or other winding up, our assets that secure secured debt will be available to pay obligations on the Notes only after all indebtedness under such secured debt has been repaid in full from such assets. We advise you that there may not be sufficient assets remaining to pay amounts due on any or all the Notes then outstanding.

Optional Redemption

Prior to the Par Call Date, we may redeem the Notes at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

plus, in either case accrued and unpaid interest thereon to the redemption date of the Notes.

Notwithstanding the foregoing, at any time on or after the Par Call Date, we may redeem some or all of the Notes at any time, or from time to time, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus, in each case, accrued and unpaid interest, if any, to, but excluding, the redemption date of the Notes.

If we choose to redeem any Notes, we will deliver a notice of redemption to holders of the Notes to be redeemed not less than 10 nor more than 60 days before the redemption date. If we are redeeming less than all of the Notes, the particular Notes to be redeemed will be selected in accordance with the applicable procedures of the trustee and, so long as the Notes are registered to DTC or its nominee, the DTC; provided, however, that no such partial redemption will reduce the portion of the principal amount of a Note not redeemed to less than $2,000. Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Notes or portions of the Notes called for redemption.

S-20

Table of Contents

For purposes of calculating the redemption price in connection with the redemption of the Notes, on any redemption date, the following terms have the meanings set forth below:

“Par Call Date” means    , 20  (one month prior to the maturity date of the Notes).

“Treasury Rate” means, with respect to any redemption date of the Notes, the yield determined by us in accordance with the following two paragraphs.

The Treasury Rate shall be determined by us after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) — H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, we shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the maturity date of the Notes (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields — one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life — and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, we shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, we shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, we shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places. Our actions and determinations in determining the redemption price of any of the Notes shall be conclusive and binding for all purposes, absent manifest error.

Offer to Repurchase Upon a Change of Control Repurchase Event

If a Change of Control Repurchase Event occurs, unless we have exercised our right to redeem the Notes in full, we will make an offer to each holder of the Notes to repurchase all or any part (in minimum denominations of $2,000 and integral multiples of $1,000 principal amount in excess thereof) of that holder’s Notes at a repurchase price in cash equal to 100% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to, but not including, the date of purchase. Within 30 days following any Change of Control Repurchase Event or, at our option, prior to any Change of Control, but after

S-21

Table of Contents

the public announcement of the Change of Control, we will mail a notice to each holder describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase Notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice will, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice. We will comply with the requirements of Rule 14e-1 promulgated under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict.

On the Change of Control Repurchase Event payment date, subject to extension if necessary to comply with the provisions of the 1940 Act and the rules and regulations promulgated thereunder, we will, to the extent lawful:

The paying agent will promptly remit to each holder of Notes properly tendered the purchase price for the Notes, and the trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered; provided that each new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

We will not be required to make an offer to repurchase the Notes upon a Change of Control Repurchase Event if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and such third party purchases all Notes properly tendered and not withdrawn under its offer.

The source of funds that will be required to repurchase Notes in the event of a Change of Control Repurchase Event will be our available cash or cash generated from our operations or other potential sources, including funds provided by a purchaser in the Change of Control transaction, borrowings, sales of assets or sales of equity. We cannot assure you that sufficient funds from such sources will be available at the time of any Change of Control Repurchase Event to make required repurchases of Notes tendered. The terms of certain of our and our subsidiaries’ financing arrangements provide that certain change of control events will constitute an event of default thereunder entitling the lenders to accelerate any indebtedness outstanding under our and our subsidiaries’ financing arrangements at that time and to terminate the financing arrangements. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Financial Condition, Liquidity and Capital Resources” in our most recent Annual Report on Form 10-K and our most recent Quarterly Reports on Form 10-Q for a general discussion of our and our subsidiaries’ indebtedness, which are incorporated by reference into this prospectus supplement. Our and our subsidiaries’ future financing arrangements may contain similar restrictions and provisions. If the holders of the Notes exercise their right to require us to repurchase Notes upon a Change of Control Repurchase Event, the financial effect of this repurchase could cause a default under our and our subsidiaries’ future financing arrangements, even if the Change of Control Repurchase Event itself would not cause a default. It is possible that we will not have sufficient funds at the time of the Change of Control Repurchase Event to make the required repurchase of the

S-22

Table of Contents

Notes and/or our and our subsidiaries’ other debt. See “Risk Factors — Risks Related to the Notes — We may not be able to repurchase the Notes upon a Change of Control Repurchase Event” in this prospectus supplement for more information.

The definition of “Change of Control” includes a phrase relating to the direct or indirect sale, transfer, conveyance or other disposition of “all or substantially all” of our properties or assets and those of our subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise, established definition of the phrase under applicable law. Accordingly, the ability of a holder of Notes to require us to repurchase the Notes as a result of a sale, transfer, conveyance or other disposition of less than all of our assets and the assets of our subsidiaries taken as a whole to another person or group may be uncertain.

For purposes of the Notes:

“Below Investment Grade Rating Event” means the Notes are downgraded below Investment Grade by all three of the Rating Agencies on any date from the date of the public notice of an arrangement that results in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period will be extended so long as the rating of the Notes is under publicly announced consideration for possible downgrade by any of the Rating Agencies); provided that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating will not be deemed to have occurred in respect of a particular Change of Control (and thus will not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control will have occurred at the time of the Below Investment Grade Rating Event).

“Change of Control” means the occurrence of any of the following:

“Change of Control Repurchase Event” means the occurrence of a Change of Control and a Below Investment Grade Rating Event.

“Controlled Subsidiary” means any subsidiary of Blackstone Secured Lending Fund, 50% or more of the outstanding equity interests of which are owned by Blackstone Secured Lending Fund and its direct or indirect

S-23

Table of Contents

subsidiaries and of which Blackstone Secured Lending Fund possesses, directly or indirectly, the power to direct or cause the direction of the management or policies, whether through the ownership of voting equity interests, by agreement or otherwise.

“Fitch” means Fitch Ratings, Inc., or any successor thereto.

“Investment Grade” means a rating of BBB- or better by Fitch (or its equivalent under any successor rating categories of Fitch), Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s) and BBB- or better by S&P (or its equivalent under any successor rating categories of S&P) (or, in each case, if such Rating Agency ceases to rate the Notes for reasons outside of our control, the equivalent investment grade credit rating from any Rating Agency selected by us as a replacement Rating Agency).

“Moody’s” means Moody’s Investors Service or any successor thereto.

“Permitted Holders” means (i) us, (ii) one or more of our Controlled Subsidiaries and (iii) the Adviser, any affiliate of the Adviser or any entity that is managed by the Adviser that is organized under the laws of a jurisdiction located in the United States and in the business of managing or advising clients.

“Rating Agency” means:

“S&P” means S&P’s Global Ratings Services, or any successor thereto.

“Voting Stock” as applied to stock of any person, means shares, interests, participations or other equivalents in the equity interest (however designated) in such person having ordinary voting power for the election of a majority of the directors (or the equivalent) of such person, other than shares, interests, participations or other equivalents having such power only by reason of the occurrence of a contingency.

Covenants

In addition to the covenants described in the base indenture, the following covenants will apply to the Notes. To the extent of any conflict or inconsistency between the base indenture and the following covenants, the following covenants will govern:

Merger, Consolidation or Sale of Assets

The indenture will provide that we will not merge or consolidate with or into any other person (other than a merger of a wholly owned subsidiary into us), or sell, transfer, lease, convey or otherwise dispose of all or substantially all our property (provided that, for the avoidance of doubt, a pledge of assets pursuant to any secured debt instrument of Blackstone Secured Lending Fund or its Controlled Subsidiaries will not be deemed to be any such sale, transfer, lease, conveyance or disposition) in any one transaction or series of related transactions unless:

S-24

Table of Contents

For the purposes of this covenant, the sale, transfer, lease, conveyance or other disposition of all the property of one or more of our subsidiaries, which property, if held by us instead of such subsidiaries, would constitute all or substantially all of our property on a consolidated basis, will be deemed to be the transfer of all or substantially all of our property.

Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve “all or substantially all” of the properties or assets of a person. As a result, it may be unclear as to whether the merger, consolidation or sale of assets covenant would apply to a particular transaction as described above absent a decision by a court of competent jurisdiction. Although these types of transactions may be permitted under the indenture, certain of the foregoing transactions could constitute a Change of Control that results in a Change of Control Repurchase Event permitting each holder to require us to repurchase the Notes of such holder as described above.

An assumption by any person of obligations under the Notes and the indenture might be deemed for U.S. federal income tax purposes to be an exchange of the Notes for new Notes by the holders thereof, resulting in recognition of gain or loss for such purposes and possibly other adverse tax consequences to the holders. Holders should consult their own tax advisors regarding the tax consequences of such an assumption.

Other Covenants

Events of Default

Each of the following will be an event of default for the Notes:

S-25

Table of Contents

If an event of default occurs and is continuing, then and in every such case (other than an event of default specified in item (6) above) the trustee or the holders of at least 25% in principal amount of the Notes may declare the entire principal amount of the outstanding Notes to be due and payable immediately, by a notice in writing to us (and to the trustee if given by the holders), and upon any such declaration such principal or specified portion thereof will become immediately due and payable. Notwithstanding the foregoing, in the case of the events of bankruptcy, insolvency or reorganization described in item (6) above, 100% of the principal of and accrued and unpaid interest on the Notes will automatically become due and payable.

At any time after a declaration of acceleration with respect to the Notes has been made and before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding Notes, by written notice to us and the trustee, may rescind and annul such declaration and its consequences if (i) we have paid or deposited with the trustee a sum sufficient to pay all overdue installments of interest, if any, on all outstanding Notes, the principal of (and premium, if any, on) all outstanding Notes that have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates borne by or provided for in such Notes, to the extent that payment of such interest is lawful interest upon overdue installments of interest at the rate or rates borne by or provided for in such Notes, and all sums paid or advanced by the trustee and the reasonable compensation, expenses, disbursements and advances of the trustee, its agents and counsel, and (ii) all events of default with respect to the Notes, other than the nonpayment of the principal of (or premium, if any, on) or interest on such Notes that have become due solely by such declaration of acceleration, have been cured or waived. No such rescission will affect any subsequent default or impair any right consequent thereon.

S-26

Table of Contents

No holder of Notes will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture, or for the appointment of a receiver or trustee, or for any other remedy under the indenture, unless:

Notwithstanding any other provision in the indenture, the holder of any Note will have the right, which is absolute and unconditional, to receive payment of the principal of (and premium, if any, on) and interest, if any, on such Note on the stated maturity or maturity expressed in such Note (or, in the case of redemption, on the redemption date or, in the case of repayment at the option of the holders, on the repayment date) and to institute suit for the enforcement of any such payment, and such rights will not be impaired without the consent of such holder.

The trustee will be under no obligation to exercise any of the rights or powers vested in it by the indenture at the request or direction of any of the holders of the Notes unless such holders have offered to the trustee security or indemnity satisfactory to the trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction. Subject to the foregoing, the holders of a majority in principal amount of the outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the Notes, provided that (i) such direction may not be in conflict with any rule of law or with the indenture, (ii) the trustee may take any other action deemed proper by the trustee that is not inconsistent with such direction and (iii) the trustee need not take any action that it determines in good faith may involve it in personal liability or be unjustly prejudicial to the holders of Notes not consenting.

The holders of not less than a majority in principal amount of the outstanding Notes may on behalf of the holders of all of the Notes waive any past default under the indenture with respect to the Notes and its consequences, except a default (i) in the payment of (or premium, if any, on) or interest, if any, on any Note, or (ii) in respect of a covenant or provision of the indenture which cannot be modified or amended without the consent of the holder of each outstanding Note affected. Upon any such waiver, such default will cease to exist, and any event of default arising therefrom will be deemed to have been cured, for every purpose, but no such waiver may extend to any subsequent or other default or event of default or impair any right consequent thereto.

We are required to deliver to the trustee, within 120 days after the end of each fiscal year, an officers’ certificate as to the knowledge of the signers whether we are in default in the performance of any of the terms, provisions or conditions of the indenture.

Within 90 days after the occurrence of any default under the indenture with respect to the Notes, the trustee must transmit notice of such default known to the trustee, unless such default has been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of (or premium, if any, on) or interest, if any, on any Note, the trustee will be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors of the trustee in good faith determines that withholding of such notice is in the interest of the holders of the Notes.

S-27

Table of Contents

Meetings of Noteholders

The indenture contains provisions relating to meetings of holders of the Notes, voting rights, conduct and adjournment of meetings, quorums, and actions that can be taken at such meetings.

Satisfaction and Discharge

We may satisfy and discharge our obligations under the indenture by delivering to the security registrar for cancellation all outstanding Notes or by depositing with the trustee or delivering to the holders, as applicable, after the Notes have become due and payable, or otherwise, moneys sufficient to pay all of the outstanding Notes and paying all other sums payable under the indenture by us. Such discharge is subject to terms contained in the indenture.

Defeasance

In addition, the Notes are subject to defeasance and covenant defeasance, in each case, in accordance with the terms of the indenture.

Covenant Defeasance

If certain conditions are satisfied, we can make the deposit described below and be released from some of the restrictive covenants in the indenture under which the Notes were issued. This is called “covenant defeasance.” In that event, you would lose the protection of those restrictive covenants but would gain the protection of having money and government securities set aside in trust to repay your Notes. In order to achieve covenant defeasance, we must do the following:

If we accomplished covenant defeasance, you can still look to us for repayment of the Notes if there were a shortfall in the trust deposit or the trustee is prevented from making payment. For example, if one of the remaining Events of Default occurred (such as our bankruptcy) and the Notes became immediately due and payable, there might be a shortfall. Depending on the event causing the default, you may not be able to obtain payment of the shortfall.

Legal Defeasance

If there is a change in U.S. federal income tax law, as described below, we can legally release ourselves from all payment and other obligations on the Notes (called “defeasance” or “legal defeasance”) if we put in place the following other arrangements for you to be repaid:

S-28

Table of Contents

If we ever accomplished legal defeasance, as described above, you would have to rely solely on the trust deposit for repayment of the Notes. You could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever became bankrupt or insolvent.

Trustee

U.S. Bank Trust Company, National Association is the trustee, security registrar and paying agent. U.S. Bank Trust Company, National Association, in each of its capacities, including without limitation as trustee, security registrar and paying agent, assumes no responsibility for the accuracy or completeness of the information concerning us or our affiliates or any other party contained in this document or the related documents or for any failure by us or any other party to disclose events that may have occurred and may affect the significance or accuracy of such information, or for any information provided to it by us, including but not limited to settlement amounts and any other information. U.S. Bank Trust Company, National Association’s address is One Federal Street, 3rd Floor, Boston, MA 02110, USA. We may maintain banking relationships in the ordinary course of business with the trustee and its affiliates.

Governing Law

The indenture provides that it and the Notes will be governed by and construed in accordance with the laws of the State of New York, without regard to principles of conflicts of laws that would cause the application of laws of another jurisdiction.

Book-Entry, Settlement and Clearance

Global Notes

The Notes will be initially issued in the form of one or more registered Notes in global form (the “Global Note”). Upon issuance, the Global Note will be deposited with the trustee as custodian for DTC and registered in the name of Cede & Co., as nominee of DTC.

Ownership of beneficial interests in a Global Note will be limited to persons who have accounts with DTC, Euroclear or Clearstream or DTC, Euroclear or Clearstream participants or persons who hold interests through DTC, Euroclear or Clearstream participants. We expect that under procedures established by DTC:

Beneficial interests in Global Notes may not be exchanged for Notes in physical, certificated form except in the limited circumstances described below.

S-29

Table of Contents

Book-Entry Procedures for Global Notes

All interests in the Global Notes will be subject to the operations and procedures of DTC. We provide the following summary of those operations and procedures solely for the convenience of investors. The operations and procedures of DTC are controlled by that settlement system and may be changed at any time. Neither we nor the underwriters are responsible for those operations or procedures.

DTC has advised us that it is:

DTC was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions between its participants through electronic book-entry changes to the accounts of its participants. DTC’s participants include securities brokers and dealers, including the underwriters; banks and trust companies; clearing corporations and other organizations. Indirect access to DTC’s system is also available to others such as banks, brokers, dealers and trust companies; these indirect participants clear through or maintain a custodial relationship with a DTC participant, either directly or indirectly. Investors who are not DTC participants may beneficially own securities held by or on behalf of DTC only through DTC participants or indirect participants in DTC.

Euroclear and Clearstream hold securities for participating organizations. They also facilitate the clearance and settlement of securities transactions between their respective participants through electronic book-entry changes in the accounts of such participants. Euroclear and Clearstream provide various services to their participants, including the safekeeping, administration, clearance, settlement, lending and borrowing of internationally traded securities. Euroclear and Clearstream interface with domestic securities markets. Euroclear and Clearstream participants are financial institutions such as underwriters, securities brokers and dealers, banks, trust companies and certain other organizations. Indirect access to Euroclear and Clearstream is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Euroclear and Clearstream participant, either directly or indirectly.

So long as the Notes are held in global form, Euroclear, Clearstream and/or DTC, as applicable, (or their respective nominees) will be considered the sole holders of Global Notes for all purposes under the indenture. As such, participants must rely on the procedures of Euroclear, Clearstream and/or DTC and indirect participants must rely on the procedures of Euroclear, Clearstream and/ or DTC and the participants through which they own interests in the Notes, or Book-Entry Interests, in order to exercise any rights of holders under the indenture.

So long as DTC, Euroclear or Clearstream’s nominee is the registered owner of a Global Note, that nominee will be considered the sole owner or holder of the Notes represented by that Global Note for all purposes under the indenture. Except as provided below, owners of beneficial interests in a Global Note:

S-30

Table of Contents

As a result, each investor who owns a beneficial interest in a Global Note must rely on the procedures of DTC, Euroclear or Clearstream to exercise any rights of a holder of Notes under the indenture (and, if the investor is not a participant or an indirect participant in DTC, Euroclear or Clearstream, on the procedures of the DTC, Euroclear or Clearstream participant through which the investor owns its interest).

Payments of principal and interest with respect to the Notes represented by a Global Note will be made by the trustee to DTC, Euroclear or Clearstream’s nominee as the registered holder of the Global Note. Neither we nor the trustee will have any responsibility or liability for the payment of amounts to owners of beneficial interests in a Global Note, for any aspect of the records relating to or payments made on account of those interests by DTC, Euroclear or Clearstream, or for maintaining, supervising or reviewing any records of DTC, Euroclear or Clearstream relating to those interests.

Payments by participants and indirect participants in DTC, Euroclear or Clearstream to the owners of beneficial interests in a Global Note will be governed by standing instructions and customary industry practice and will be the responsibility of those participants or indirect participants and DTC, Euroclear or Clearstream.

Transfers between participants in DTC, Euroclear or Clearstream will be effected under DTC, Euroclear or Clearstream’s procedures and will be settled in same-day funds.

Cross-market transfers of beneficial interests in Global Notes between DTC participants, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected within DTC through the DTC participants that are acting as depositaries for Euroclear and Clearstream. To deliver or receive an interest in a Global Note held in a Euroclear or Clearstream account, an investor must send transfer instructions to Euroclear or Clearstream, as the case may be, under the rules and procedures of that system and within the established deadlines of that system. If the transaction meets its settlement requirements, Euroclear or Clearstream, as the case may be, will send instructions to its DTC depositary to take action to effect final settlement by delivering or receiving interests in the relevant Global Notes in DTC, and making or receiving payment under normal procedures for same-day funds settlement applicable to DTC. Euroclear and Clearstream participants may not deliver instructions directly to the DTC depositaries that are acting for Euroclear or Clearstream.

Because the settlement of cross-market transfers takes place during New York business hours, DTC participants may employ their usual procedures for sending securities to the applicable DTC participants acting as depositaries for Euroclear and Clearstream. The sale proceeds will be available to the DTC participant seller on the settlement date. Thus, to a DTC participant, a cross-market transaction will settle no differently from a trade between two DTC participants. Because of time zone differences, the securities account of a Euroclear or Clearstream participant that purchases an interest in a Global Note from a DTC participant will be credited on the business day for Euroclear or Clearstream immediately following the DTC settlement date. Cash received in Euroclear or Clearstream from the sale of an interest in a Global Note to a DTC participant will be reflected in the account of the Euroclear of Clearstream participant the following business day, and receipt of the cash proceeds in the Euroclear or Clearstream participant’s account will be back-valued to the date on which settlement occurs in New York. DTC, Euroclear and Clearstream have agreed to the above procedures to facilitate transfers of interests in the Global Notes among participants in those settlement systems. However, the settlement systems are not obligated to perform these procedures and may discontinue or change these procedures at any time. Neither we nor the trustee will have any responsibility or liability for the performance by DTC, Euroclear or Clearstream or their participants or indirect participants of their obligations under the rules and procedures governing their operations, including maintaining, supervising or reviewing the records relating to, or payments made on account of, beneficial ownership interests in Global Notes.

CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain United States federal income tax consequences of the purchase, ownership and disposition of the Notes. This summary deals only with Notes held as capital assets (within the meaning of Section 1221 of the Code) by persons who purchase the Notes for cash upon original issuance at their “issue price” (the first price at which a substantial amount of the Notes is sold for money to investors, excluding sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriter, placement agent or wholesaler).

As used herein, a “U.S. holder” means a beneficial owner of the Notes that is, for United States federal income tax purposes, any of the following:

As used herein, a “non-U.S. holder” means a beneficial owner of the Notes (other than an entity or arrangement classified as a partnership for United States federal income tax purposes) that is not a U.S. holder.

If any entity or arrangement classified as a partnership for United States federal income tax purposes holds Notes, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership or a partner in a partnership considering an investment in the Notes, you should consult your own tax advisors.

This summary does not represent a detailed description of the United States federal income tax consequences applicable to you if you are a person subject to special tax treatment under the United States federal income tax laws, including, without limitation:

S-33

Table of Contents

This summary is based on the Code, United States Treasury regulations, administrative rulings and judicial decisions as of the date hereof. Those authorities may be changed, possibly on a retroactive basis, so as to result in United States federal income tax consequences different from those summarized below. We have not sought and will not seek any rulings from the Internal Revenue Service (“IRS”) regarding the matters discussed below. There can be no assurance that the IRS will not take positions concerning the tax consequences of the purchase, ownership or disposition of the Notes that are different from those discussed below.

This summary does not represent a detailed description of the United States federal income tax consequences to you in light of your particular circumstances, and does not address any United States federal taxes other than income taxes (such as estate and gift taxes), the Medicare tax on certain investment income or any state, local or non-U.S. tax laws. It is not intended to be, and should not be construed to be, legal or tax advice to any particular purchaser of Notes. We expect, and this summary assumes, that the Notes will be issued with less than a de minimis amount of original issue discount.

If you are considering the purchase of Notes, you should consult your own tax advisors concerning the particular United States federal income tax consequences to you of the purchase, ownership and disposition of the Notes, as well as the consequences to you arising under other United States federal tax laws and the laws of any other taxing jurisdiction.

Certain Tax Consequences to U.S. Holders

The following is a summary of certain United States federal income tax consequences that will apply to U.S. holders of the Notes.

Stated Interest. Stated interest on the Notes generally will be taxable to you as ordinary income at the time it is received or accrued, depending on your method of accounting for United States federal income tax purposes.

Sale, Exchange, Retirement, Redemption or Other Taxable Disposition of Notes. Upon the sale, exchange, retirement, redemption or other taxable disposition of a Note, you generally will recognize gain or loss equal to the difference, if any, between the amount realized upon the sale, exchange, retirement, redemption or other taxable disposition (less any amount attributable to accrued and unpaid stated interest, which will be treated in the manner described above) and the adjusted tax basis of the Note. Your adjusted tax basis in a Note will, in general, be your cost for that Note. Any gain or loss will generally be capital gain or loss and will generally be long-term capital gain or loss if you have held the Note for more than one year. Long-term capital gains of non-corporate U.S. holders (including individuals) are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

In certain circumstances, United States Treasury regulations require losses in excess of a threshold amount to be reported to the IRS. U.S. holders should consult their tax advisors to determine any reporting obligations they may have with respect to the sale, exchange, retirement, redemption or other taxable disposition of a Note.

Certain Tax Consequences to Non-U.S. Holders

The following is a summary of certain United States federal income tax consequences that will apply to non-U.S. holders of the Notes.

United States Federal Withholding Tax. Subject to the discussions of backup withholding and FATCA below, United States federal withholding tax will not apply to any payment of interest on the Notes under the “portfolio interest rule,” provided that:

If you cannot satisfy the requirements described above, payments of interest made to you will be subject to a 30% United States federal withholding tax, unless you provide the applicable withholding agent with a properly executed:

The 30% United States federal withholding tax generally will not apply to any payment of principal or gain that you realize on the sale, exchange, retirement, redemption or other taxable disposition of a Note.

United States Federal Income Tax. If you are engaged in a trade or business in the United States and interest on the Notes is effectively connected with the conduct of that trade or business (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment), then you will be subject to United States federal income tax on that interest on a net income basis in generally the same manner as if you were a United States person as defined under the Code (although you will be exempt from the 30% withholding tax described above, provided the certification requirements discussed above in “— United States Federal Withholding Tax” are satisfied). In addition, if you are a foreign corporation, you may be subject to a branch profits tax equal to 30% (or a lower applicable income tax treaty rate) of your effectively connected earnings and profits, subject to adjustments.

Subject to the discussion of backup withholding below, any gain realized on the sale or other taxable disposition of a Note generally will not be subject to United States federal income tax unless:

Information Reporting and Backup Withholding

U.S. Holders. In general, information reporting requirements will apply to payments of stated interest on the Notes and the proceeds of the sale or other taxable disposition (including a retirement or redemption) of a Note paid to you (unless you establish that you are an exempt recipient such as a corporation). Backup withholding may apply to any payments described in the preceding sentence if you fail to provide a correct taxpayer identification number and a certification that you are not subject to backup withholding.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against your United States federal income tax liability provided the required information is timely furnished to the IRS.

Non-U.S. Holders. Generally, the amount of interest paid to you and the amount of tax, if any, withheld with respect to those payments will be reported to the IRS. Copies of the information returns reporting such interest payments and any withholding may also be made available to the tax authorities in the country in which you reside under the provisions of an applicable income tax treaty.

In general, you will not be subject to backup withholding with respect to payments of interest on the Notes that we make to you, provided that the applicable withholding agent does not have actual knowledge or reason to know that you are a United States person as defined under the Code, and such withholding agent has received from you the required certification that you are a non-U.S. holder described above in the fifth bullet point under “— Certain Tax Consequences to Non-U.S. Holders — United States Federal Withholding Tax.”

Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale or other taxable disposition (including a retirement or redemption) of Notes within the United States or conducted through certain United States-related financial intermediaries, unless you certify to the payor under penalties of perjury that you are a non-U.S. holder (and the payor does not have actual knowledge or reason to know that you are a United States person as defined under the Code), or you otherwise establish an exemption.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against your United States federal income tax liability provided the required information is timely furnished to the IRS.

Foreign Account Tax Compliance Act

Under Sections 1471 through 1474 of the Code (such Sections commonly referred to as “FATCA”), a 30% United States federal withholding tax may apply to any interest paid on the Notes to (i) a “foreign financial institution” (as specifically defined in the Code and whether such foreign financial institution is the beneficial owner or an intermediary) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) its compliance (or deemed compliance) with FATCA (which may alternatively be in the form of compliance with an intergovernmental agreement with the United States) in a manner which avoids withholding, or (ii) a “non-financial foreign entity” (as specifically defined in the Code and whether such non-financial foreign entity is the beneficial owner or an intermediary) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) adequate information regarding certain substantial United States beneficial owners of such entity (if any). If an interest payment is both subject to withholding under FATCA and subject to the withholding

Table of Contents

tax discussed above under “— Certain Tax Consequences to Non-U.S. Holders — United States Federal Withholding Tax,” an applicable withholding agent may credit the withholding under FATCA against, and therefore reduce, such other withholding tax. While withholding under FATCA would also have applied to payments of gross proceeds from the sale or other taxable disposition of the Notes, proposed United States Treasury regulations (upon which taxpayers may rely until final regulations are issued) eliminate FATCA withholding on payments of gross proceeds entirely. You should consult your own tax advisors regarding these rules and whether they may be relevant to your purchase, ownership and disposition of the Notes.

UNDERWRITING

Citigroup Global Markets Inc., Barclays Capital Inc., Goldman Sachs & Co. LLC, RBC Capital Markets, LLC and SMBC Nikko Securities America, Inc. are acting as representatives of each of the several underwriters named below. Subject to the terms and conditions set forth in an underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the aggregate principal amount of Notes set forth opposite its name below.

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the Notes sold under the underwriting agreement if any of these Notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”), or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the Notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the Notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officers’ certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commissions and Discounts

The following table shows the per Note and total underwriting discount that we are to pay to the underwriters in connection with this offering.

The underwriters propose to offer some of the Notes to the public at the public offering price set forth on the cover page of this prospectus supplement, and some of the Notes to certain other Financial Industry Regulatory Authority, or FINRA, members at the public offering price less a concession not in excess of   % of the aggregate principal amount of the Notes. The underwriters may allow, and the dealers may reallow, a discount not in excess of     % of the aggregate principal amount of the Notes. After the initial offering of the Notes to the public, the public offering price and such concessions may be changed. No such change shall change the amount of proceeds to be received by us as set forth on the cover page of this prospectus supplement.

The expenses of the offering, not including the underwriting discount, are estimated at $    million and are payable by us.

S-38

No Sales of Similar Securities

Subject to certain exceptions, we have agreed not to directly or indirectly, offer, pledge, sell, contract to sell, grant any option for the sale of or otherwise transfer or dispose of any debt securities issued or guaranteed by us or any securities convertible into or exercisable or exchangeable for debt securities issued or guaranteed by us or file any registration statement under the Securities Act with respect to any of the foregoing through the closing date of this offering without first obtaining the written consent of the representatives. This consent may be given at any time without public notice.

Listing

The Notes are a new issue of securities with no established trading market. The Notes will not be listed on any securities exchange or quoted on any automated dealer quotation system.

We have been advised by certain of the underwriters that they currently intend to make a market in the Notes after completion of the offering as permitted by applicable laws and regulations. The underwriters are not obligated, however, to make a market in the Notes and any such market-making may be discontinued at any time in the sole discretion of the underwriters without any notice. Accordingly, no assurance can be given as to the liquidity of, or development of a public trading market for, the Notes. If an active public trading market for the Notes does not develop, the market price and liquidity of the Notes may be adversely affected.

Price Stabilization, Short Positions

In connection with the offering, the underwriters may purchase and sell Notes in the open market. These transactions may include over-allotment, covering transactions and stabilizing transactions. Over-allotment involves sales of Notes in excess of the aggregate principal amount of Notes to be purchased by the underwriters in the offering, which creates a short position for the underwriters. Covering transactions involve purchases of the Notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions consist of certain bids or purchases of Notes made for the purpose of preventing or retarding a decline in the market price of the Notes while the offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives has repurchased Notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

Any of these activities may cause the price of the Notes to be higher than the price that otherwise would exist in the open market in the absence of such transactions. These transactions may be effected in the over-the-counter market or otherwise and, if commenced, may be discontinued at any time without any notice relating thereto.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Notes. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage, valuation services and other financial and non-financial activities and services. Certain of the underwriters and their respective affiliates have provided, currently provide, and may in the future provide, a variety of these services to us and to

S-39

Table of Contents

persons and entities with relationships with us, for which they received or will receive customary fees and expenses. For example, certain of the underwriters and their affiliates were underwriters in connection with the Company’s initial public offering and our subsequent debt and equity offerings, for which they received customary fees. Additionally, affiliates of certain underwriters are lenders under the credit facilities of the Company and its subsidiaries.

In the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively traded securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to assets, securities or instruments of us (directly, as collateral securing other obligations or otherwise) or persons and entities with relationships with us. Certain of the underwriters and their affiliates that have a lending relationship with us routinely hedge their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes offered hereby. The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long or short positions in such assets, securities and instruments.

The net proceeds of this offering may be used to pay down a portion of the outstanding indebtedness under the Revolving Credit Facility or the SPV Financing Facilities. Affiliates of certain of the underwriters are lenders under the Revolving Credit Facility or the SPV Financing Facilities. Accordingly, affiliates of certain of the underwriters may receive more than 5% of the proceeds of this offering to the extent such proceeds are used to repay or repurchase outstanding indebtedness under the Revolving Credit Facility or the SPV Financing Facilities.

Certain funds or accounts managed by the affiliates of the Adviser may purchase Notes in the transaction through the underwriters at the public offering price.

Settlement

We expect that delivery of the Notes will be made to investors on or about    , 2024, which will be the      business day following the date hereof. Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes on the date hereof or the next succeeding two business days will be required by virtue of the fact that the Notes initially settle in T+ , to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes on the date hereof or the next      succeeding business days should consult their own advisor.
