Statements\n\nThis report may contain forward-looking statements, which involve certain known and unknown risks and uncertainties. Forward-looking statements predict or describe our future operations, business plans, business and investment strategies, portfolio management and the performance of our investments. These forward-looking statements are generally identified by their use of such terms and phrases as “intend,” “goal,” “estimate,” “expect,” “project,” “projections,” “plans,” “seeks,” “anticipates,” “will,” “should,” “could,” “may,” “designed to,” “foreseeable future,” “believe,” “scheduled” and similar expressions. Our actual results or outcomes may differ materially from those anticipated. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date the statement was made. Potential investors should not rely on these statements as if they were fact. We assume no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.\n\nReferences herein to “expertise” or any party being an “expert” are based solely on the belief of Blackstone (as defined below) and are intended only to indicate proficiency as compared to an average person and in no way limit any exculpation provisions or alter any standard of care applicable to Blackstone. Additionally, any awards, honors, or other references or rankings referred to herein with respect to Blackstone or any investment professional are provided solely for informational purposes and are not intended to be, nor should they be construed or relied upon as, any indication of future performance or other future activity. Any such awards, honors, or other references or rankings may have been based on subjective criteria and may have been based on a limited universe of participants, and there are other awards, honors, or other references or rankings given to others and not received by Blackstone and/or any investment professional of Blackstone.\n\nThere are or will be important factors that could cause actual outcomes or results to differ materially from those indicated in these statements. We believe these factors include, but are not limited to, those described under the section entitled “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2025, as such factors may be updated from time to time in our periodic filings with the United States Securities and Exchange Commission (the “SEC”), which are accessible on the SEC’s website at www.sec.gov or on our website at www.bxinfra.com. These factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements that are included in this report and in our other periodic filings. The forward-looking statements speak only as of the date of this report, and we undertake no obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise. Our website contains additional information about our business, but the contents of the website are not incorporated by reference in, or otherwise a part of, this report.\n\n________________________\n\nIn this report, except where the context suggests otherwise:\n\nThe term “Aggregator” refers to BXINFRA Aggregator (CYM) L.P.

Parallel Funds may be established to allow certain investors with particular legal, tax, regulatory, compliance, structuring or certain other operational requirements to participate in the Aggregator. Parallel Funds may not have investment objectives and/or strategies that are identical to the investment objectives and strategies of BXINFRA U.S. or the Feeder. One or more such Parallel Funds invest directly, or indirectly through one or more Intermediate Entities in the Aggregator alongside BXINFRA U.S.\n\nThe term “Portfolio Entity” refers to any individual, partnership, corporation, limited liability company, unincorporated organization or association, trust (including the trustees thereof, in their capacity as such) or other entity, in which Investments are made by BXINFRA U.S.\n\nThe term “Sponsor” refers to, as the context or applicable law requires, individually and collectively, the General Partner and the Investment Manager.\n\nThe term “Transactional NAV” refers to the price at which transactions in BXINFRA U.S.’s Units (as defined below) are made (as the context requires), calculated in accordance with a valuation policy that has been approved by BXINFRA U.S.’s board of directors (“Board of Directors” or “Board”).

The financial statements of each entity are presented in “Part I. Item 1. Financial Statements.” See also “Part I. Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.”\n\nThis report does not constitute an offer of BXINFRA or any Other Blackstone Accounts.\n\n3\n\nPart I.
