(1)
and $130.5 million

The Funds invest alongside other Blackstone-managed vehicles with substantially similar investment objectives and strategies that, together with the Funds, collectively form the “BXPE Fund Program.” On September 1, 2025, the BXPE Fund Program (inclusive of the Funds) issued interests for aggregate consideration of approximately $740.0 million.
(2)
The Feeder was established to allow certain investors with particular tax characteristics, such as
tax-exempt
investors and
non-U.S.
investors, to participate in BXPE U.S. in a more tax efficient manner. Accordingly, the Feeder invests all or substantially all of its assets indirectly in BXPE U.S. in exchange for BXPE U.S. Class I Units. On September 1, 2025, the Feeder acquired 4,024,580 BXPE U.S. Class I Units for aggregate consideration of approximately $129.3 million.
(3)
The number of Units sold by each Fund was finalized on September 29, 2025, following the calculation of their respective transactional net asset values (each, a “Transactional NAV”) as of August 31, 2025. See Item 7.01 below for more information on the Funds’ Transactional NAVs.
The offer and sale of the Units were made as part of the Funds’ continuous private offerings to investors that are both (a) accredited investors (as defined in Regulation D under the Securities Act of 1933, as amended (the “Securities Act”)) and (b) qualified purchasers (as defined in the Investment Company Act of 1940, as amended, and the rules thereunder) and were exempt from the registration provisions of the Securities Act pursuant to Section 4(a)(2) and Regulation D thereunder.
 
Item 7.01
Regulation FD Disclosure
Transactional Net Asset Value
The Transactional NAV per Unit for each class of the Funds as of August 31, 2025, is as follows:
 
    
Transactional NAV

as of August 31, 2025
 
Blackstone Private Equity Strategies Fund L.P.
  
Class I Unit
   $ 32.12  
Class S Unit
   $ 31.67  
Class D Unit
   $ 31.99  
Class N Unit
   $ 25.46  
Blackstone Private Equity Strategies Fund (TE) L.P.
  
Class I Unit
   $ 31.86  
Class S Unit
   $ 31.41  
Class D Unit
   $ 28.46  
 
1

As of August 31, 2025, the BXPE Fund Program’s aggregate Transactional NAV was approximately $14.2 billion.
The Funds calculate Transactional NAV for purposes of establishing the price at which transactions in their respective Units are made. A description of the Funds’ valuation process was included under “
Part II, Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities—Calculation of Net Asset Value
” of BXPE U.S.’s Annual Report on Form 10-K filed on March 14, 2025. Transactional NAV is based on the
month-end
values of each Fund’s respective investments and other assets and the deduction of any respective liabilities, including certain fees and expenses, in all cases as determined in accordance with the valuation policy that has been approved by BXPE U.S. board of directors. Organizational and offering expenses advanced on the Funds’ behalf by the investment manager are recognized as a reduction to Transactional NAV ratably over 60 months beginning on January 1, 2025, and unitholder servicing fees, as applicable, are recognized as a reduction to Transactional NAV on a monthly basis as such fees are accrued. Certain contingent tax liabilities may not be recognized as a reduction to Transactional NAV if the Funds’ general partner reasonably expects such liabilities will not be recognized upon divestment of the underlying investment. Transactional NAV per Unit may differ from each Fund’s net asset value as determined in accordance with accounting principles generally accepted in the United States of America.
