BXINFRA U.S., at the direction of the General Partner, has the authority to issue an unlimited number of Units of each class, or series of a class. As of December 31, 2025, BXINFRA U.S. offered three classes of limited partnership Units: Class I, Class S and Class D Units. The key differences among each class, or series of a class, of Units relate to the ongoing servicing fees, the upfront subscription fee and distribution channels. The term “Transactional NAV” refers to the price at which transactions in BXINFRA U.S. are made, calculated in accordance with a valuation policy that has been approved by the Board of Directors. The purchase price per Unit is equal to the Transactional NAV per Unit for such class, or series of a class, as of the last calendar day of the immediately preceding month. Before BXINFRA U.S. determined its first Transactional NAV, the initial subscription price for Units was $25.00 per Unit plus applicable subscription fees that are paid by the unitholder outside its investment in BXINFRA U.S. and not reflected in BXINFRA U.S.’s Transactional NAV. The Transactional NAV for each class, or series of a class, of Units was first determined as of the end of the first full month after the Initial Closing Date. Thereafter, BXINFRA U.S.’s Transactional NAV is based on the month-end values of investments, the addition of the value of any other assets such as cash, the deduction of any liabilities and the deduction of expenses attributable to certain classes, or series of classes, such as applicable servicing fees. At the end of each month, BXINFRA U.S. allocates its Net Investment Income (Loss) and Net Change in Unrealized Gain (Loss) on Investment in the Aggregator across each class, or series of a class, of Units based on their relative ownership share in BXINFRA U.S. as of the first calendar day of that month. From time to time, the Sponsor, out of its own resources and without additional cost to BXINFRA or its investors, may offer other discounts, waivers or other incentives to investors. Unit issuances related to monthly subscriptions are effective the first calendar day of each month. Units are issued at a price per Unit equivalent to BXINFRA U.S.’s most recent Transactional NAV per Unit available for each class, or series of a class, of Units, which is BXINFRA U.S.’s prior month-end Transactional NAV per Unit. The following tables present transactions in the Units during the periods:
Unit Redemption Plan In accordance with the BXINFRA U.S. Partnership Agreement (as defined below), BXINFRA U.S. expects to periodically redeem up to 3% of its Units outstanding (the “Unit Redemption Plan”). Under the Unit Redemption Plan, to the extent BXINFRA U.S. redeems Units in any particular quarter, BXINFRA U.S. expects to use a purchase price equal to the Transactional NAV per Unit as of the date specified in the Unit Redemption Plan. Any redemption requests of Units that have been outstanding for less than two years will be subject to an early redemption deduction equal to 5% of the value of such Transactional NAV of the Units being redeemed, subject to certain exceptions in the General Partner’s sole discretion (the “Early Redemption Deduction”). Any Early Redemption Deduction will be retained by BXINFRA U.S. for the benefit of all investors. In accordance with the terms of the Feeder’s limited partnership agreement, unitholders of the Feeder, as indirect holders of BXINFRA U.S., participate in BXINFRA U.S.’s Unit Redemption Plan under the same terms as direct unitholders of BXINFRA U.S. Accordingly, a redemption request by a unitholder of the Feeder will be satisfied by redeeming the same number of Units in BXINFRA U.S. If the quarterly volume limitation is reached in any particular calendar quarter or the General Partner determines to redeem fewer Units than have been requested to be redeemed in any particular calendar quarter, Units submitted for redemption during such quarter will be redeemed on a pro-rata basis after BXINFRA U.S. has redeemed all Units for which redemption has been requested due to death, disability or divorce and other limited exceptions. Unsatisfied redemption requests will not be automatically carried over to the next redemption period and, in order for a redemption request to be reconsidered, unitholders must resubmit their request in the next available redemption window. The General Partner, with the approval of the Independent Directors, as applicable, may make exceptions to, modify or suspend the Unit Redemption Plan if, in its reasonable judgment, it deems such action to be in the best interest of BXINFRA U.S. and its unitholders (including the Feeder), including, but not limited to, for tax, regulatory or other structuring reasons. As a result, Unit redemptions may not be available each quarter, such as when redemptions would place an undue burden on BXINFRA U.S.’s liquidity, adversely affect its operations or pose a potential adverse impact on BXINFRA U.S. that would outweigh the benefit of the redemptions. BXINFRA U.S. accepted its first redemptions pursuant to the Unit Redemption Plan on April 15, 2025. During the year ended December 31, 2025, Units were redeemed for an aggregate value, net of the Early Redemption Deduction, of $ million, of which 5,154 Units at an aggregate value of $ 0.1million related to redemptions by the Feeder. Distributions BXINFRA U.S. may declare quarterly distributions as authorized by the General Partner and may pay such distributions to unitholders on a quarterly basis. The following table presents a summary of the aggregate distributions declared and payable for the year ended December 31, 2025 for each applicable class of Units.
Distribution Reinvestment Plan BXINFRA U.S. has adopted an “opt out” DRIP for unitholders. When a cash distribution is declared, each unitholder that has not “opted out” of the DRIP prior to the payment date will have their distributions automatically reinvested in additional Units rather than receive cash distributions, for a purchase price equal to the most recently available Transactional NAV per Unit for such Unit. Distributions on fractional Units will be credited to each participating unitholder’s account to three decimal places. Investors and clients of certain participating brokers that do not permit automatic enrollment in BXINFRA U.S.’s DRIP will automatically receive their distributions in cash unless they elect to have their cash distributions reinvested in additional Units. Unitholders will not pay subscription fees when purchasing Units under the DRIP. For the year ended December 31, 2025, $17.8 million, $12.6 million and $1.3 million of distributions were reinvested in Class I, Class S and Class D Units, respectively. |

The Aggregator, at the direction of the General Partner, has the authority to issue an unlimited number of Class A Units and Class B Units (each, an “Aggregator Unit”). No Class B Units have been issued by the Aggregator since inception. As of December 31, 2025, the Aggregator has two limited partners, BXINFRA U.S. and a Parallel Fund. Class A Units are issued to both the BXINFRA U.S. limited partner and the Parallel Fund limited partner. BXINFRA U.S. and the Parallel Fund receive monthly subscriptions from their investors, which are in turn invested into the Aggregator. BXINFRA U.S. and the Parallel Fund are issued Class A Units in exchange for their contributions to the Aggregator. The term “Transactional NAV” refers to the price at which transactions in the Aggregator’s Units are made, calculated in accordance with a valuation policy that has been approved by the BXINFRA U.S. Board of Directors. The purchase price per Aggregator Unit of each limited partner is equal to the Transactional NAV per Aggregator Unit for such limited partner as of the last calendar day of the immediately preceding month. Before the Aggregator determined its first Transactional NAV, the initial purchase price for the Aggregator’s Units was $25.00 per Aggregator Unit. The Aggregator’s Transactional NAV was first determined as of the end of the first full month after the Initial Closing Date. Thereafter, the Transactional NAV is based on the month-end values of investments, the addition of the value of any other assets such as cash, the deduction of any liabilities, the accrual and allocation of the Management Fee, Administration Fee and the Performance Participation Allocation (each as defined in Note 8. “Related Party Transactions”) and the deduction of expenses. Aggregator Unit issuances related to monthly contributions are effective the first calendar day of each month. Aggregator Units are issued at a price per Aggregator Unit equivalent to the Aggregator’s most recent Transactional NAV per Aggregator Unit available for Class A Units, which is the Aggregator’s prior month-end Transactional NAV per Aggregator Unit. The following table presents transactions in the Aggregator’s Units during the periods:
In accordance with the Aggregator Partnership Agreement, the General Partner can cause the Aggregator to redeem Aggregator Units from limited partners to match any redemptions made by BXINFRA U.S. and any Parallel Fund. Any redemption of Aggregator Units will be effected by the Aggregator as needed to comply with the redemption plan of BXINFRA U.S. and any Parallel Fund and otherwise as determined by the General Partner. A Parallel Fund may withdraw entirely from the Aggregator and have all of its Aggregator Units redeemed by the Aggregator only with the consent of BXINFRA U.S., including, if applicable, approval by the Board of Directors. Distributions The Aggregator may declare quarterly distributions on Aggregator Units as authorized by the General Partner. The following tables present a summary of the aggregate distributions declared and payable for the year ended December 31, 2025 for each applicable class of Units.
Distribution Reinvestment Plan When a cash distribution is declared, each Aggregator unitholder that has not “opted out” of the Distribution Reinvestment Plan (“DRIP”) prior to the payment date will have their distributions automatically reinvested in additional Aggregator Units rather than receive cash distributions, for a purchase price equal to the most recently available Transactional NAV per Aggregator Unit for such Aggregator Unit. For further details on the DRIP, see Note 5. “Net Assets” in the “Notes to Financial Statements” of BXINFRA U.S. For the year ended December 31, 2025, $ 32.2 million of distributions were reinvested in Class A Units. |
