currently effective Prospectus and Statement of Additional Information ("SAI")

for each of the funds listed in Appendix A (each, a "Fund")

On or around November 10, 2025, Citibank, N.A. ("Citibank") will become the administrator, custodian and transfer agent for each Fund. Effective upon this change, the following changes will be made:

Administrator, Custodian and Transfer Agent. Citibank serves as administrator, custodian and transfer agent for the Funds under the Master Services Agreement (the "Master Services Agreement"). Citibank's principal address is 388 Greenwich Street, New York, NY 10013. Pursuant to the Master Services Agreement with the Trust, Citibank provides necessary administrative, tax and accounting and financial reporting services for the maintenance and operations of the Trust and each Fund. In addition, Citibank makes available the office space, equipment, personnel and facilities required to provide such services. Pursuant to the Master Services Agreement with the Trust, Citibank maintains, in separate accounts, cash, securities and other assets of the Trust and each Fund, keeps all necessary accounts and records and provides other services. Citibank is required, upon the order of the Trust, to deliver securities held by Citibank and to make payments for securities purchased by the Trust for each Fund. Citibank is authorized to appoint certain foreign custodians or foreign custody managers for Fund investments outside the U.S. Pursuant to the Master Services Agreement with the Trust, Citibank acts as a transfer agent for each Fund's authorized and issued shares of beneficial interest, and as dividend disbursing agent of the Trust. As compensation for these services, Citibank receives certain out-of-pocket costs, transaction fees and asset-based fees which are accrued daily and paid monthly by BFA. BFA pays the compensation because it has agreed to pay these operating expenses under the Investment Advisory Agreement as described therein.

Prior to November 10, 2025, State Street Bank and Trust Company ("State Street") served as administrator, custodian and transfer agent for each Fund.

Costs Associated with Creation Transactions.

A standard creation transaction fee is imposed to offset the transfer and other transaction costs associated with the issuance of Creation Units. Under an ETF Services Agreement, the Funds have retained BRIL, an affiliate of BFA, to perform the ETF Services. BRIL will receive from an Authorized Participant a standard transaction fee on each creation order, which consists of (1) a fee for providing the ETF Services (the "ETF Servicing Fee") and (2) transfer, processing and other transaction costs charged by a Fund custodian in connection with the issuance of Creation Units for such creation order ("Custody Transaction Costs"). BRIL is entitled to retain the ETF Servicing Fee pursuant to the ETF Services Agreement, but BRIL will reimburse any Custody Transaction Costs to the applicable Fund custodian according to the amounts invoiced by such custodian.

The ETF Servicing Fee is a flat fee per order regardless of the number of Creation Units being purchased, which amount will vary among different Funds based on a number of factors, including the complexity of the order and the types of securities or instruments included in a Fund's Creation Basket, among other variables. The ETF Servicing Fee may be equal to zero in certain instances, such as for creation transactions that consist solely of cash. The actual Custody Transaction Costs vary per order based on the number of trades, underlying markets and settlement locations associated with the issuance of a Creation Unit. The following table sets forth, for each Fund, an estimate of the creation transaction fee for a Creation Unit based on data as of October 1, 2025. The actual fee charged to an Authorized Participant in connection with a creation order will vary over time depending on the factors discussed above, and may be higher than the fee set forth below.

In order to defray transaction expenses for a Fund and protect against possible shareholder dilution, if a creation transaction consists solely or partially of cash, the Authorized Participant may also be required to cover (up to the maximum amount shown below) certain brokerage, tax, foreign exchange, execution and other costs and expenses related to the execution of trades resulting from such transaction (which may, in certain instances, be based on a good faith estimate of transaction costs based on historical data or other inputs, at BlackRock's discretion, and may include part or all of the spread between the expected bid and offer side of the market and anticipated market impact). However, a Fund is not obligated to trade identical securities to the securities identified by BlackRock in estimating these transaction and other costs and expenses. In certain cases, BlackRock or an affiliate may determine in its discretion to deviate from the regular charge, subject to the maximum amounts shown below.

Authorized Participants will also bear the costs of transferring the Deposit Securities to the Funds. Certain fees/costs associated with creation transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to acquire Fund shares may be charged a fee for such services.

The following table sets forth each Fund's estimated creation transaction fee based on data as of October 1, 2025 and maximum additional charge (as described above):

Costs Associated with Redemption Transactions.

A standard redemption transaction fee is imposed to offset transfer and other transaction costs that may be incurred by the relevant Fund. As described above, under an ETF Services Agreement, the Funds have retained BRIL, an affiliate of BFA, to perform certain ETF Services. BRIL will receive from an Authorized Participant a standard transaction fee on each redemption order, which consists of (1) the ETF Servicing Fee and (2) Custody Transaction Costs. BRIL is entitled to retain the ETF Servicing Fee pursuant to the ETF Services Agreement, but BRIL will reimburse any Custody Transaction Costs to the applicable Fund custodian according to the amounts invoiced by such custodian.

The ETF Servicing Fee is a flat fee per order regardless of the number of Creation Units being redeemed, which amount will vary among different Funds based on a number of factors, including the complexity of the order and the types of securities or instruments included in a Fund's Redemption Basket, among other variables.

The actual fee charged to an Authorized Participant in connection with a redemption order will vary over time depending on the factors discussed above, and may be higher than the fee set forth below.
