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, trade policies, 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 Private Credit Strategies LLC (the “Adviser”), Blackstone Credit BDC Advisors LLC (the “Sub-Adviser” and together with the Adviser, the “Advisers”) or any of their 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 macroeconomic effects;

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

•the impact of future acquisitions and divestitures;

•the ability of the Advisers or their 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 (“RIC”) 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, 2024 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, whether as a result of new information, future developments or otherwise, 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”).
