Q3 2025 Quarterly Update

Important Disclosure Information

This material was not created by any third-party registered broker-dealers or investment advisers who are distributing shares of BMACX (each, a “Dealer”). The Dealers are not affiliated with BMACX and have not prepared the material or the information herein.

Investments mentioned may not be in the best interest of, or is suitable for, all investors. Any product discussed herein may be purchased only after an investor has carefully reviewed the prospectus and executed the subscription documents.

Alternative investments often are speculative, typically have higher fees than traditional investments, often include a high degree of risk and are in the best interest of, or suitable for, eligible, long-term investors who are willing to forgo liquidity and put capital at risk for an indefinite period of time. They may be highly illiquid and can engage in leverage and other speculative practices that may increase volatility and risk of loss.

Although certain loans in which the Fund may invest will be secured by collateral, there can be no assurance that such collateral could be readily liquidated or that the liquidation of such collateral would satisfy the borrower’s obligation in the event of non-payment of scheduled interest or principal.

Blackstone products are subject to the risk of capital loss and investors may not get back the amount originally invested.

Further, opinions expressed herein may differ from the opinions expressed by a Dealer and/or other businesses / affiliates of a Dealer. This is not a “research report” as defined by FINRA Rule 2241 and was not prepared by the research departments of a Dealer or its affiliates.

Blackstone Securities Partners L.P. (“BSP”) is a member of FINRA and is a broker-dealer whose purpose is to distribute Blackstone managed or affiliated products. BSP provides services to its Blackstone affiliates, not to investors in its funds, strategies or other products. BSP does not make any recommendation regarding, and will not monitor, any investment. As such, when BSP presents an investment strategy or product to an investor, BSP does not collect the information necessary to determine and BSP does not engage in a determination regarding whether an investment in the strategy or product is in the best interests of, or is suitable for, the investor. You should exercise your own judgment and/or consult with a professional advisor to determine whether it is advisable for you to invest in any Blackstone strategy or product. Please note that BSP may not provide the kinds of financial services that you might expect from another financial intermediary, such as overseeing any brokerage or similar account. For financial advice relating to an investment in any Blackstone strategy or product, contact your own professional advisor.

Past performance does not predict future returns. Actual results may vary. Diversification of an investor’s portfolio does not assure a profit or protect against loss in a declining market.

Alternative investments involve complex tax structures, tax inefficient investing, and delays in distributing important tax information. Individual funds have specific risks related to their investment programs that will vary from fund to fund. Investors should consult their own tax and legal advisors as Dealers generally do not provide tax or legal advice. BDCs are generally not taxed at the corporate level to the extent they distribute all of their taxable income in the form of dividends. Ordinary income dividends are taxed at individual tax rates and distributions may be subject to state tax. Each investor’s tax considerations are different and consulting a tax advisor is recommended. Any of the data provided herein should not be construed as investment, tax, accounting or legal advice.

Interests in alternative investment products are distributed by the applicable Dealer and (1) are not FDIC-insured, (2) are not deposits or other obligations of such Dealer or any of its affiliates, and (3) are not guaranteed by such Dealer and its affiliates. Each Dealer is a registered broker-dealer or investment adviser, not a bank.

Use of Leverage. The Fund currently uses leverage. The use of leverage or borrowings magnifies investment, market and certain other risks and may be significant. The Fund’s performance will be affected by the availability and terms of any leverage as such leverage will enhance returns from investments to the extent such returns exceed the costs of borrowings by the Fund. The leveraged capital structure of such assets will increase their exposure to certain factors such as rising interest rates, downturns in the economy, or deterioration in the financial condition of such assets or industry. In the event an investment cannot generate adequate cash flow to meet its debt service, the Fund may suffer a partial or total loss of capital invested in the investment, which may adversely affect the returns of the Fund. In addition, because the Fund will pay all expenses, including interest, associated with the use of leverage or borrowings, investors will indirectly bear such cost.

Past performance does not predict future returns. The opinions expressed herein reflect the current opinions of Blackstone as of the date appearing in this material only. There can be no assurance that views and opinions expressed in this document will come to pass. Certain information contained in the materials discusses general market activity, industry or sector trends, or other broad-based economic, market or political conditions and should not be construed as research or investment advice.

Forward-Looking Statement Disclosure. Certain information contained in this communication constitutes “forward looking statements” within the meaning of the federal securities laws. These forward-looking statements can be identified by the use of forward-looking terminology, such as “outlook,” “indicator,” “believes,” “expects,” “potential,” “continues,” “may,” “can,” “could,” “will,” “should,” “seeks,” “approximately,” “predicts,” “intends,” “plans,” “estimates,” “anticipates”, “confident,” “conviction,” “identified” or the negative versions of these words or other comparable words thereof. These may include financial projections and estimates and their underlying assumptions, statements about plans, objectives and expectations with respect to future operations, statements regarding future performance, statements regarding economic and market trends and statements regarding identified but not yet closed investments. Such forward-looking statements are inherently subject to various risks and uncertainties. Accordingly, there are or will be important factors that could cause actual outcomes or results to differ materially from those indicated in such statements. BMACX believes these factors also include but are not limited to those described under the section entitled “Risk Factors” in its prospectus, and any such updated factors included in its periodic filings with the Securities and Exchange Commission (the “SEC”), which are accessible on the SEC’s website at www.sec.gov. These factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements that are included in this document (or BMACX’s prospectus and other filings). Except as otherwise required by federal securities laws, BMACX undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future developments or otherwise.

Conflicts of Interest. There may be occasions when a Fund’s general partner and/or the investment advisor, and their affiliates will encounter potential conflicts of interest in connection with such Fund’s activities including, without limitation, the allocation of investment opportunities, relationships with Blackstone’s and its affiliates’ investment banking and advisory clients, and the diverse interests of such Fund’s limited partner group. There can be no assurance that Blackstone will identify, mitigate, or resolve all conflicts of interest in a manner that is favorable to the Fund.

Exchange Rate. Currency fluctuations may have an adverse effect on the value, price, income or costs of the product which may increase or decrease as a result of changes in exchange rates.

Limited Operating History. Prospective investors should note that the Fund has recently commenced operations and therefore has limited operating history upon which prospective investors may evaluate its performance. Past activities of investment vehicles managed or sponsored by Blackstone provide no assurance of future success. Moreover, the prior investment results of the existing BXCI Funds are provided for illustrative purposes only and not to imply that such results will be obtained in the future.

Recent Market Events Risk. Local, regional, or global events such as war (e.g., Russia/Ukraine), acts of terrorism, public health issues like pandemics or (e.g., COVID-19), recessions, or other economic, political and global macro factors and events could lead to a substantial economic downturn or recession in the U.S. and global economies and have a significant impact on the Fund and its investments. The recovery from such downturns is uncertain and may last for an extended period of time or result in significant volatility, and many of the risks discussed herein associated with an investment in the Fund may be increased.

Third Party Information. Certain information contained in this material has been obtained from sources outside Blackstone, which in certain cases have not been updated through the date hereof. While such information is believed to be reliable for purposes used herein, no representations are made as to the accuracy or completeness thereof and none of Blackstone, its funds, nor any of their affiliates takes any responsibility for, and has not independently verified, any such information. This information involves a number of assumptions and limitations, and you are cautioned not to give undue weight to these estimates.

Trends. There can be no assurances that any of the trends described herein will continue or will not reverse. Past events and trends do not imply, predict or guarantee, and are not necessarily indicative of, future events or results.

Additional Risks. The Fund and the investment in it is subject to further risks, including those related to unspecified use of proceeds, shareholder suitability, drawdowns of capital commitments, termination of the investment period, dependence on key individuals, retention and motivation of key employees, replacement of the Adviser, diverse shareholder group, enhanced scrutiny of the alternative investment industry, availability of leverage, non-US investments, anti-money laundering, limited liquidity, incentive allocation, policies and procedures of Blackstone and its affiliates, in-kind distributions, and investments with other clients.

Summary of Key Risk Factors

BMACX is a non-diversified, closed-end management company that is registered under the Investment Company Act of 1940, as amended, and operates as an interval fund. The Fund expects to be invested in across private corporate credit, asset based and real estate credit, structured credit, and liquid credit. This investment involves a high degree of risk. You should purchase our Common Shares only if you can afford a complete loss of your investment. You should read the prospectus carefully for a description of the risks associated with an investment in the Fund. Some of the more significant risks relating to an investment in our Common Shares include the following:

• There is no assurance that we will achieve our investment objectives.


• You should not expect to be able to sell all or most of your Common Shares regardless of how we perform.


• You should consider that you may not have access to the money you invest for an extended period of time.


• We do not intend to list our Common Shares on any securities exchange, and we do not expect a secondary market in our Common Shares to develop prior to any listing.


• Because you may be unable to sell your Common Shares, you may be unable to reduce your exposure in any market downturn.


• We have elected to operate as an “interval fund” and will make quarterly repurchase offers, but only a limited number of Common Shares will be eligible for repurchase and the need to fund repurchase obligations may affect our ability to be fully invested or force us to maintain a higher percentage of assets in liquid investments, which may harm our investment performance.


• An investment in the Fund is suitable only for investors who can bear the risks associated with limited liquidity. See “Share Repurchase Program” in the prospectus.


• You will bear substantial fees and expenses in connection with your investment. See “Fees and Expenses” in the prospectus.


• We cannot guarantee that we will make distributions, and if we do, we may fund such distributions from sources other than net investment income, including the sale of assets, borrowings, return of capital or offering proceeds, and although we generally expect to fund distributions from net investment income, we have not established limits on the amounts we may pay from such sources. A return of capital is not paid from tax earnings or profits and will have the effect of reducing the tax basis of a shareholder’s Common Shares, such that when a shareholder sells its Common Shares the sale may be subject to tax, even if the Common Shares are sold for less than the original purchase price.


• Distributions may also be funded in significant part, directly or indirectly, from temporary waivers or expense reimbursements borne by the Adviser or its affiliates, that may be subject to reimbursement to the Adviser or its affiliates. The repayment of any amounts owed to our affiliates will reduce future distributions to which you would otherwise be entitled.


• The Fund intends to utilize leverage and may utilize leverage to the maximum extent permitted by law for investment and other general corporate purposes, which will magnify the potential for loss on amounts invested in the Fund. See “Leverage,” “Risks—Leverage Risk” and “Description of Shares—Preferred Shares” in the prospectus.


• We intend to invest in securities that are rated below investment grade by rating agencies or that would be rated below investment grade if they were rated. Below investment grade securities, which are often referred to as “junk,” have predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal. They may also be illiquid and difficult to value.

Neither the Securities and Exchange Commission nor any state securities regulator has approved or disapproved of these securities or determined if the Fund’s prospectus is truthful or complete. Any representation to the contrary is unlawful.

The words “we”, “us”, and “our” refer to BMACX, unless the context requires otherwise.

Index Comparison. The volatility and risk profile of the index presented in this document is likely to be materially different from those of BMACX, including those related to fees and expenses, liquidity, safety, and tax features.
