Costs paid as a percentage of a

iShares AAA CLO Active ETF $21 0.20%
How did the Fund perform last year?
  • For the reporting period ended July 31, 2025, the Fund returned 6.09%.
  • For the same period, the Bloomberg U.S. Universal Index returned 4.00%, and the J.P. Morgan Collateralized Loan Obligation AAA Index returned 5.97%.
What contributed to performance?
The largest contributor to the Fund’s absolute return was portfolio yield as the Secured Overnight Financing Rate which serves as the base rate for CLOs benefited from the U.S. Federal Reserve holding short term policy rates steady over the time frame. In addition, discount margins on the floating rate securities held generally tightened over the period, despite some volatility in April of 2025, resulting in a modest contribution from price appreciation. Modest allocations to CLOs rated AA and A also proved additive.
What detracted from performance?
There were no material detractors from performance.

How did the Fund perform last year?
  • For the reporting period ended July 31, 2025, the Fund returned 6.50%.
  • For the same period, the Bloomberg U.S. Universal Index returned 4.00%.
What contributed to performance?
For the 12-month period, positive contributions to the Fund’s performance were led by exposures to U.S. high yield and European high yield corporate bonds. The allocation to securitized assets including commercial mortgage-backed securities, collateralized loan obligations, asset-backed securities and non-agency residential mortgage-backed securities also proved additive. Positioning with respect to duration and corresponding interest rate sensitivity in emerging markets as well as in European and other developed international markets also contributed to return. Other contributors included exposures to emerging market hard currencies, agency mortgage-backed securities and European investment grade corporate bonds.
The Fund utilized derivatives to help manage interest rate and credit exposures, as well as to hedge foreign currency exposures. The use of derivatives contributed modestly to the Fund’s performance during the period.
What detracted from performance?
The Fund’s positioning with respect to duration and corresponding interest rate sensitivity in the U.S. market weighed most heavily on return over the 12-month period. Exposure to U.S. investment grade corporate bonds also detracted from performance.

How did the Fund perform last year?
  • For the reporting period ended July 31, 2025, the Fund returned 7.04%.
  • For the same period, the Bloomberg U.S. Universal Index returned 4.00%, and the Morningstar LSTA Leveraged Loan Index returned 7.50%.
What contributed to performance?
The core allocation to bank loans was the primary contributor to the Fund’s absolute return. The overall bank loan market experienced strong performance over the period, returning 7.50%. Allocations to both high yield corporate bonds and bank loans via indexed products also contributed positively to performance, as both asset classes posted strong returns over the period. In terms of credit categories, issues rated BB and higher led positive contributions, followed by those rated B2 and B3. In sector terms, holdings within technology, diversified manufacturing, and property & casualty insurance proved most additive.
What detracted from performance?
While there were no material detractors from performance, holdings within the lodging and construction machinery sectors detracted very slightly.

How did the Fund perform last year?
  • For the reporting period ended July 31, 2025, the Fund returned 2.01%.
  • For the same period, the Bloomberg Municipal Bond Index returned 0.00%, the Bloomberg Municipal Bond 3-10 Year Index returned 3.44%, and the Bloomberg Custom Blend Benchmark returned 1.98%.
What contributed to performance?
Income, which offset the impact of falling prices and widening yield spreads, was the key contributor to performance. At the sector level, transportation and corporate-backed issues made the largest contributions.
What detracted from performance?
Positions in longer-duration securities, which posted negative total returns, detracted from performance. (Duration is a measure of interest rate sensitivity.) The decision to add to the Fund’s weighting in the intermediate-term portion of the yield curve during the course of the period detracted from results.

How did the Fund perform last year?
  • For the reporting period ended July 31, 2025, the Fund returned 3.26%.
  • For the same period, the Bloomberg Municipal Bond Index returned 0.00%, and the Bloomberg California Municipal 0-2 Year Index returned 3.24%.
What contributed to performance?
Holdings in longer-dated securities—those with maturities of up to five years—in the corporate, prepaid gas, and transportation sectors contributed to performance, as did select holdings in the school district, tax-backed state, and tax-backed local categories. A focus on variable rate demand notes (VRDNs) and tender option bond floaters (TOBs) as core holdings, which in the adviser’s view featured both attractive yields and price stability, also contributed. Select commercial paper purchases, which offered additional yield and short maturity profiles, further helped results in a volatile interest rate environment. In terms of credit tiers, holdings in AA and A rated bonds had the strongest influence on the Fund’s performance.
What detracted from performance?
At a time of positive return for the California municipal market, there were no meaningful detractors from absolute returns.

How did the Fund perform last year?
  • For the reporting period ended July 31, 2025, the Fund returned 3.59%.
  • For the same period, the Bloomberg U.S. Aggregate Bond Index returned 3.38%.
What contributed to performance?
Over the 12-month period, economic growth generally surprised to the upside and credit sensitive sectors across fixed income performed well despite elevated interest rate volatility. Positive contributions to the Fund’s performance were led by the allocation to securitized assets including commercial mortgage-backed securities, non-agency mortgage-backed securities, collateralized loan obligations and asset-backed securities. The Fund’s allocation to and positioning within both investment grade corporate bonds and agency mortgage-backed securities also proved additive, along with an allocation to high yield corporate bonds.
What detracted from performance?
The Fund’s positioning with respect to duration and corresponding interest rate sensitivity was a modest detractor from performance over the period.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:

The Committee has adopted policies and procedures with regard to the pre-approval of services. Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the Investment Adviser and Affiliated Service Providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are (a) consistent with the SEC’s auditor independence rules and (b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis (“general pre-approval”). The term of any general pre-approval is 12 months from the date of the pre-approval, unless the Committee provides for a different period. Tax or other non-audit services provided to the registrant which have a direct impact on the operations or financial reporting of the registrant will only be deemed pre-approved provided that any individual project does not exceed $10,000 attributable to the registrant or $50,000 per project. For this purpose, multiple projects will be aggregated to determine if they exceed the previously mentioned cost levels.

Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting. At this meeting, an analysis of such services is presented to the Committee for ratification. The Committee may delegate to the Committee Chairman the authority to approve the provision of and fees for any specific engagement of permitted non-audit services, including services exceeding pre-approved cost levels.


(e)(2) None of the services described in each of Items 4(b) through (d) were approved by the Committee pursuant to the de minimis exception in paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not Applicable

(g) The aggregate non-audit fees, defined as the sum of the fees shown under “Audit-Related Fees,” “Tax Fees” and “All Other Fees,” paid to the accountant for services rendered by the accountant to the registrant, the Investment Adviser and the Affiliated Service Providers were:

On September 13, 2024, The Board of Trustees of the Trust (the “Board”) approved to change the name of iShares High Yield Muni Income Active ETF to iShares Short Duration High Yield Muni Active ETF. In connection with the Fund’s name change, the Fund made certain changes to its investment strategies, including (i) seeking a weighted average effective duration of less than 5 years and (ii) adding the ability to invest in derivatives, other investment companies, and tender option bonds. These changes were effective on July 1, 2025.
The Funds, together with certain other registered investment companies advised by BlackRock Fund Advisors (“BFA” or the “Manager”) or its affiliates, are included in a complex of funds referred to as the BlackRock Fixed-Income Complex.
2. SIGNIFICANT ACCOUNTING POLICIES
The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. Each Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies. Below is a summary of significant accounting policies:
InvestmentTransactions and Income Recognition: For financial reporting purposes, investment transactions are recorded on the dates the transactions are executed. Realized gains and losses on investment transactions are determined using the specific identification method. Dividend income and capital gain distributions, if any, are recorded on the ex-dividend date. Non-cash dividends, if any, are recorded on the ex-dividend date at fair value. Upon notification from issuers or as estimated by management, a portion of the dividend income received from a real estate investment trust may be redesignated as a reduction of cost of the related investment and/or realized gain. Interest income, including amortization and accretion of premiums and discounts on debt securities, is recognized daily on an accrual basis.
Foreign CurrencyTranslation: Each Fund's books and records are maintained in U.S. dollars. Securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars using exchange rates determined as of the close of trading on the New York Stock Exchange (“NYSE”). Purchases and sales of investments are recorded at the rates of exchange prevailing on the respective dates of such transactions. Generally, when the U.S. dollar rises in value against a foreign currency, the investments denominated in that currency will lose value; the opposite effect occurs if the U.S. dollar falls in relative value.
Each Fund does not isolate the effect of fluctuations in foreign exchange rates from the effect of fluctuations in the market prices of investments for financial reporting purposes. Accordingly, the effects of changes in exchange rates on investments are not segregated in the Statements of Operations from the effects of changes in market prices of those investments, but are included as a component of net realized and unrealized gain (loss) from investments. Each Fund reports realized currency gains (losses) on foreign currency related transactions as components of net realized gain (loss) for financial reporting purposes, whereas such components are generally treated as ordinary income for U.S. federal income tax purposes.  
Cash: The Funds may maintain cash at their custodian which, at times may exceed United States federally insured limits. The Funds may, at times, have outstanding cash disbursements that exceed deposited cash amounts at the custodian during the reporting period. The Fundsare obligated to repay the custodian for any overdraft, including any related costs or expenses, where applicable. For financial reporting purposes, overdraft fees, if any, are included in interest expense in the Statements of Operations.
Notes to Financial Statements
166

Notes to Financial Statements  (continued)
Collateralization: If required by an exchange or counterparty agreement, the Funds may be required to deliver/deposit cash and/or securities to/with an exchange, or broker-dealer or custodian as collateral for certain investments.
In-kind Redemptions: For financial reporting purposes, in-kind redemptions are treated as sales of securities resulting in realized capital gains or losses to the Funds. Because such gains or losses are not taxable to the Funds and are not distributed to existing Fund shareholders, the gains or losses are reclassified from accumulated net realized gain (loss) to paid-in capital at the end of the Funds’ tax year. These reclassifications have no effect on net assets or net asset value (“NAV”) per share.
Distributions: Dividends and distributions paid by each Fund are recorded on the ex-dividend dates. Distributions are determined on a tax basis and may differ from net investment income and net realized capital gains for financial reporting purposes. Dividends and distributions are paid in U.S. dollars and cannot be automatically reinvested in additional shares of the Funds.
Indemnifications: In the normal course of business, each Fund enters into contracts that contain a variety of representations that provide general indemnification. The Funds’ maximum exposure under these arrangements is unknown because it involves future potential claims against the Funds, which cannot be predicted with any certainty.
Segment Reporting:  The Funds adopted Financial Accounting Standards Board Update 2023-07, Segment Reporting (Topic 280) – Improvements to Reportable Segment Disclosures (“ASU 2023-07”) during the period. The Funds’ adoption of the new standard impacted financial statement disclosures only and did not affect each Fund’s financial position or results of operations.
The Chief Financial Officer acts as the Funds’ Chief Operating Decision Maker (“CODM”) and is responsible for assessing performance and allocating resources with respect to each Fund. The CODM has concluded that each Fund operates as a single operating segment since each Fund has a single investment strategy as disclosed in its prospectus, against which the CODM assesses performance. The financial information provided to and reviewed by the CODM is presented within each Fund's financial statements.  
3. INVESTMENTVALUATION AND FAIR VALUE MEASUREMENTS
Investment Valuation Policies: Each Fund’s investments are valued at fair value (also referred to as “market value” within the financial statements) each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date.  U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Board of each Fund has approved the designation of BFA , the Funds' investment adviser, as the valuation designee for each Fund. Each Fund determines the fair values of its financial instruments using various independent dealers or pricing services under BFA’s policies. If a security’s market price is not readily available or does not otherwise accurately represent the fair value of the security, the security will be valued in accordance with BFA’s policies and procedures as reflecting fair value. BFAhas formed a committee (the “Valuation Committee”) to develop pricing policies and procedures and to oversee the pricing function for all financial instruments, with assistance from other BlackRock pricing committees.
Fair Value Inputs and Methodologies: The following methods and inputs are used to establish the fair value of each Fund’s assets and liabilities:
• Equity investments traded on a recognized securities exchange are valued at that day’s official closing price, as applicable, on the exchange where the stock is primarily traded. Equity investments traded on a recognized exchange for which there were no sales on that day are valued at the last traded price.
• Fixed-income investments for which market quotations are readily available are generally valued using the last available bid price provided by independent dealers or third-party pricing services. Floating rate loan interests are valued at the mean of the bid prices from one or more independent brokers or dealers as obtained from a third-party pricing service.Pricing services generally value fixed income securities assuming orderly transactions of an institutional round lot size, but a fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots of securities in certain asset classes may trade at lower prices than institutional round lots, and the value ultimately realized when the securities are sold could differ from the prices used by a fund. The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data (e.g., recent representative bids and offers), market data, credit quality information, perceived market movements, news, and other relevant information. Certain fixed-income securities, including asset-backed and mortgage related securities may be valued based on valuation models that consider the estimated cash flows of each tranche of the entity, establish a benchmark yield and develop an estimated tranche specific spread to the benchmark yield based on the unique attributes of the tranche. The amortized cost method of valuation may be used with respect to debt obligations with sixty days or less remaining to maturity unless BFA determines such method does not represent fair value.
• Exchange-traded funds and closed-end funds traded on a recognized securities exchange are valued at that day’s official closing price, as applicable, on the exchange where the fund is primarily traded. Funds traded on a recognized exchange for which there were no sales on that day may be valued at the last traded price.
• Investments in open-end U.S. mutual funds (including money market funds) are valued at that day’s NAV.
• Futures contracts are valued based on that day’s last reported settlement or trade price on the exchange where the contract is traded.
• Forward foreign currency exchange contracts are valued at the mean between the bid and ask prices and are determined as of the close of trading on the New York Stock Exchange (“NYSE”) based on that day’s prevailing forward exchange rate for the underlying currencies.

2025 BlackRock Annual Financial Statements and Additional Information

Notes to Financial Statements  (continued)
• Swap agreements are valued utilizing quotes received daily by independent pricing services or through brokers, which are derived using daily swap curves and models that incorporate a number of market data factors, such as discounted cash flows, trades and values of the underlying reference instruments.
• Exchange-traded options are valued at the mean between the last bid and ask prices at the close of the options market in which the options trade. An exchange-traded option for which there is no mean price is valued at the last bid (long positions) or ask (short positions) price. If no bid or ask price is available, the prior day’s price will be used, unless it is determined that the prior day’s price no longer reflects the fair value of the option.
If events (e.g., market volatility, company announcement or a natural disaster) occur that are expected to materially affect the value of such investment, or in the event that application of these methods of valuation results in a price for an investment that is deemed not to be representative of the market value of such investment, or if a price is not available, the investment will be valued by the Valuation Committee in accordance with BFA’s policies and procedures as reflecting fair value (“Fair Valued Investments”). The fair valuation approaches that may be used by the Valuation Committee include market approach, income approach and cost approach. Valuation techniques such as discounted cash flow, use of market comparables and matrix pricing are types of valuation approaches and are typically used in determining fair value. When determining the price for Fair Valued Investments, the Valuation Committee seeks to determine the price that each Fund might reasonably expect to receive or pay from the current sale or purchase of that asset or liability in an arm’s-length transaction. Fair value determinations shall be based upon all available factors that the Valuation Committee deems relevant and consistent with the principles of fair value measurement as of the measurement date.
For investments in equity or debt issued by privately held companies or funds (“Private Company” or collectively, the “Private Companies”) and other Fair Valued Investments, the fair valuation approaches that are used by the Valuation Committee and third-party pricing services utilized by the Valuation Committee include one or a combination of, but not limited to, the following inputs:
(i)recent market transactions, including secondary market transactions, merger or acquisition activity and subsequent rounds of financing in the underlying investment or comparable issuers
(ii)recapitalizations and other transactions across the capital structure
(iii)market or relevant indices multiples of comparable issuers
(iv)future cash flows discounted to present and adjusted as appropriate for liquidity, credit, and/or market risks
(v)quoted prices for similar investments or assets in active markets
(vi)other risk factors, such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, recovery rates, liquidation amounts and/or default rates
(vii)audited or unaudited financial statements, investor communications and Private Company financial or operational metrics
(viii)relevant market news and other public sources.
Investments in series of preferred stock issued by Private Companies are typically valued utilizing a market approach to determine the enterprise value of the company. Such investments often contain rights and preferences that differ from other series of preferred and common stock of the same issuer. Enterprise valuation techniques such as an option pricing model (“OPM”), a probability weighted expected return model (“PWERM”), current value method or a hybrid of those techniques are used as deemed appropriate under the circumstances. The use of these valuation techniques involves a determination of the exit scenarios of the investment in order to appropriately allocate the enterprise value of the company among the various parts of its capital structure.
Private Companies are not subject to public company disclosure, timing, and reporting standards applicable to other investments held by a Fund. Certain information made available by a Private Company is as of a date that is earlier than the date a Fund is calculating its NAV. This factor may result in a difference between the value of the investment and the price a Fund could receive upon the sale of the investment.
Fair Value Hierarchy: Various inputs are used in determining the fair value of financial instruments at the measurement date. These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial reporting purposes as follows: 
• Level 1 – Unadjusted price quotations in active markets/exchanges that each Fund has the ability to access for identical assets or liabilities;
• Level  2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and
• Level 3 – Inputs that are unobservable and significant to entire fair value measurement for the asset or liability (including the Valuation Committee’s assumptions used in determining the fair value of financial instruments). 
The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. Investments classified within Level 3 have significant unobservable inputs used by the Valuation Committee in determining the price for Fair Valued Investments. Level 3 investments include equity or debt issued by Private Companies that may not have a secondary market and/or may have a limited number of investors. The categorization of a value determined for financial instruments is based on the pricing transparency of the financial instruments and is not necessarily an indication of the risks associated with investing in those securities.

4. SECURITIES AND OTHER INVESTMENTS
Asset-Backed and Mortgage-Backed Securities: Asset-backed securities are generally issued as pass-through certificates or as debt instruments. Asset-backed securities issued as pass-through certificates represent undivided fractional ownership interests in an underlying pool of assets. Asset-backed securities issued as debt instruments, which are also known as collateralized obligations, are typically issued as the debt of a special purpose entity organized solely for the purpose of owning such assets and issuing such debt. Asset-backed securities are often backed by a pool of assets representing the obligations of a number of different parties. The yield characteristics of certain asset-backed securities may differ from traditional debt securities. One such major difference is that all or a principal part of the obligations may be prepaid at any time because the underlying assets (i.e., loans) may be prepaid at any time. As a result, a decrease in interest rates in the market may result in increases in the level of prepayments as borrowers, particularly mortgagors, refinance and repay their loans. An increased prepayment rate with respect to an asset-backed security will have the effect of shortening the maturity of the security. In addition, a fund may subsequently have to reinvest the proceeds at lower interest rates. If a fund has purchased such an asset-backed security at a premium, a faster than anticipated prepayment rate could result in a loss of principal to the extent of the premium paid.
For mortgage pass-through securities (the “Mortgage Assets”) there are a number of important differences among the agencies and instrumentalities of the U.S. Government that issue mortgage-related securities and among the securities that they issue. For example, mortgage-related securities guaranteed by Ginnie Mae are guaranteed as to the timely payment of principal and interest by Ginnie Mae and such guarantee is backed by the full faith and credit of the United States. However, mortgage-related securities issued by Freddie Mac and Fannie Mae, including Freddie Mac and Fannie Mae guaranteed mortgage pass-through certificates, which are solely the obligations of Freddie Mac and Fannie Mae, are not backed by or entitled to the full faith and credit of the United States, but are supported by the right of the issuer to borrow from the U.S. Treasury.
Non-agency mortgage-backed securities are securities issued by non-governmental issuers and have no direct or indirect government guarantees of payment and are subject to various risks. Non-agency mortgage loans are obligations of the borrowers thereunder only and are not typically insured or guaranteed by any other person or entity. The ability of a borrower to repay a loan is dependent upon the income or assets of the borrower. A number of factors, including a general economic downturn, acts of God, terrorism, social unrest and civil disturbances, may impair a borrower’s ability to repay its loans.
Collateralized Debt Obligations: Collateralized debt obligations (“CDOs”), including collateralized bond obligations (“CBOs”) and collateralized loan obligations (“CLOs”), are types of asset-backed securities. A CDO is an entity that is backed by a diversified pool of debt securities (CBOs) or syndicated bank loans (CLOs). The cash flows of the CDO can be split into multiple segments, called “tranches,” which will vary in risk profile and yield. The riskiest segment is the subordinated or “equity” tranche. This tranche bears the greatest risk of defaults from the underlying assets in the CDO and serves to protect the other, more senior, tranches from default in all but the most severe circumstances. Since it is shielded from defaults by the more junior tranches, a “senior” tranche will typically have higher credit ratings and lower yields than their underlying securities, and often receive investment grade ratings from one or more of the nationally recognized rating agencies. Despite the protection from the more junior tranches, senior tranches can experience substantial losses due to actual defaults, increased sensitivity to future defaults and the disappearance of one or more protecting tranches as a result of changes in the credit profile of the underlying pool of assets.
Zero-Coupon Bonds: Zero-coupon bonds are normally issued at a significant discount from face value and do not provide for periodic interest payments. These bonds may experience greater volatility in market value than other debt obligations of similar maturity which provide for regular interest payments.
TBA Commitments: TBAcommitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate and mortgage terms. When entering into TBAcommitments, a fund may take possession of or deliver the underlying mortgage-backed securities but can extend the settlement or roll the transaction. TBA commitments involve a risk of loss if the value of the security to be purchased or sold declines or increases, respectively, prior to settlement date, if there are expenses or delays in connection with the TBA transactions, or if the counterparty fails to complete the transaction.
To mitigate counterparty risk, a fund enters into a two-way collateral agreement for TBAtransactions with certain counterparties. Under such agreement, the “in-the-money” party of a TBAtransaction may at any time require the other party to pledge collateral assets (in the form of cash or securities) to offset any loss the in-the-money party would incur upon cancellation of the TBA transaction. A party is in-the-money if they are the buyer and the market value of the TBAtransaction increases or if they are the seller and the market value of the TBAtransaction decreases. Cash collateral received from the counterparty may be reinvested in money market funds, including those managed by the Funds’ investment adviser, or its affiliates. Such collateral, if any, is noted in the Schedule of Investments and the obligation to return the collateral is presented as a liability in the Statements of Assets and Liabilities. Securities pledged as collateral by a fund, if any, are noted in the Schedule of Investments.
Mortgage Dollar Roll Transactions: The Funds may sell TBA mortgage-backed securities and simultaneously contract to repurchase substantially similar (i.e., same type, coupon and maturity) securities on a specific future date at an agreed upon price. During the period between the sale and repurchase, a fund is not entitled to receive interest and principal payments on the securities sold. Mortgage dollar roll transactions are treated as purchases and sales and a fund realizes gains and losses on these transactions. Mortgage dollar rolls involve the risk that the market value of the securities that a fund is required to purchase may decline below the agreed upon repurchase price of those securities.
Securities Lending: Each Fund may lend its securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Fund collateral consisting of cash, an irrevocable letter of credit issued by an approved bank, or securities issued or guaranteed by the U.S. government. The initial collateral received by each Fund is required to have a value of at least 102% of the current market value of the loaned securities for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current value of the securities on loan. The market value of the loaned securities is determined at the close of each business day of the Fund and any additional required collateral is delivered to the Fund or excess collateral is returned by the Fund, on the next business day. During the term of the loan, each Fund is entitled to all distributions made on or in respect of the loaned

securities but does not receive interest income on securities received as collateral. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions.
As of period end, any securities on loan were collateralized by cash and/or U.S. Government obligations. Cash collateral invested in money market funds managed by BFA, or its affiliates is disclosed in the Schedule of Investments. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan, if any, are also disclosed in each Fund’s Schedule of Investments. The market value of any securities on loan and the value of any related cash collateral are disclosed in the Statements of Assets and Liabilities.
Securities lending transactions are entered into by the Funds under Master Securities LendingAgreements (each, an “MSLA”) which provide the right, in the event of default (including bankruptcy or insolvency) for the non-defaulting party to liquidate the collateral and calculate a net exposure to the defaulting party or request additional collateral. In the event that a borrower defaults, the Funds, as lender, would offset the market value of the collateral received against the market value of the securities loaned. When the value of the collateral is greater than that of the market value of the securities loaned, the lender is left with a net amount payable to the defaulting party. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of an MSLA counterparty’s bankruptcy or insolvency. Under the MSLA, absent an event of default, the borrower can resell or re-pledge the loaned securities, and the Funds can reinvest cash collateral received in connection with loaned securities. Upon an event of default, the parties’ obligations to return the securities or collateral to the other party are extinguished, and the parties can resell or re-pledge the loaned securities or the collateral received in connection with the loaned securities in order to satisfy the defaulting party’s net payment obligation for all transactions under the MSLA. The defaulting party remains liable for any deficiency.
As of period end, the following table is a summary of the securities on loan by counterparty which are subject to offset under an MSLA:

Collateral received, if any, in excess of the market value of securities on loan is not presented in this table. The total cash collateral received by each Fund is disclosed in the Fund’s
Statements of Assets and Liabilities.
The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, each Fund benefits from a borrower default indemnity provided by BlackRock Finance, Inc. BlackRock Finance, Inc.'s indemnity allows for full replacement of the securities loaned to the extent the collateral received does not cover the value of the securities loaned in the event of borrower default. Each Fund could incur a loss if the value of an investment purchased with cash collateral falls below the market value of the loaned securities or if the value of an investment purchased with cash collateral falls below the value of the original cash collateral received. Such losses are borne entirely by each Fund.
Floating Rate Loan Interests: Floating rate loan interests are typically issued to companies (the “borrower”) by banks, other financial institutions, or privately and publicly offered corporations (the “lender”). Floating rate loan interests are generally non-investment grade, often involve borrowers whose financial condition is troubled or uncertain and companies that are highly leveraged or in bankruptcy proceedings. In addition, transactions in floating rate loan interests may settle on a delayed basis, which may result in proceeds from the sale not being readily available for a fund to make additional investments or meet its redemption obligations. Floating rate loan interests may include fully funded term loans or revolving lines of credit. Floating rate loan interests are typically senior in the corporate capital structure of the borrower. Floating rate loan interests generally pay interest at rates that are periodically determined by reference to a base lending rate plus a premium. Since the rates reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the NAV of a fund to the extent that it invests in floating rate loan interests. The base lending rates are generally the lending rate offered by one or more European banks, such as the Secured Overnight Financing Rate (“SOFR”), the prime rate offered by one or more U.S. banks or the certificate of deposit rate. Floating rate loan interests may involve foreign borrowers, and investments may be denominated in foreign currencies. These investments are treated as investments in debt securities for purposes of a fund’s investment policies.
When a fund purchases a floating rate loan interest, it may receive a facility fee and when it sells a floating rate loan interest, it may pay a facility fee. On an ongoing basis, a fund may receive a commitment fee based on the undrawn portion of the underlying line of credit amount of a floating rate loan interest. Facility and commitment fees are typically amortized to income over the term of the loan or term of the commitment, respectively. Consent and amendment fees are recorded to income as earned. Prepayment penalty fees, which may be received by a fund upon the prepayment of a floating rate loan interest by a borrower, are recorded as realized gains. A fund may invest in multiple series or tranches of a loan. A different series or tranche may have varying terms and carry different associated risks.
Floating rate loan interests are usually freely callable at the borrower’s option. A fund may invest in such loans in the form of participations in loans (“Participations”) or assignments (“Assignments”) of all or a portion of loans from third parties. Participations typically will result in a fund having a contractual relationship only with the lender, not with the borrower. A fund has the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the Participation and only upon receipt by the lender of the payments from the borrower. In connection with purchasing Participations, a fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement, nor any rights of offset against the borrower. A fund may not benefit directly from any collateral supporting the loan in which it has purchased the Participation. As a result, a fund assumes the credit risk of both the borrower and the lender that is selling the Participation. A fund’s investment in loan participation interests involves the risk of insolvency of the financial intermediaries who are parties to the transactions. In the event of the insolvency of the lender selling the Participation, a fund may be treated as a general creditor of the lender and may not benefit from any offset between the lender and the borrower. Assignments typically result in a fund having a direct contractual relationship with the borrower, and a fund may enforce compliance by the borrower with the terms of the loan agreement.
In connection with floating rate loan interests, the Funds may also enter into unfunded floating rate loan interests (“commitments”). In connection with these commitments, a fund earns a commitment fee, typically set as a percentage of the commitment amount. Such fee income, which is included in interest income in the Statements of Operations, is recognized ratably over the commitment period. Unfunded floating rate loan interests are marked-to-market daily, and any unrealized appreciation

5. DERIVATIVE FINANCIAL INSTRUMENTS
Futures Contracts: Futures contracts are purchased or sold to gain exposure to, or manage exposure to, changes in interest rates (interest rate risk) and changes in the value of equity securities (equity risk) or foreign currencies (foreign currency exchange rate risk).
Futures contracts are exchange-traded agreements between the Funds and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and on a specified date. Depending on the terms of a contract, it is settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash amount on the settlement date. Upon entering into a futures contract, the Funds are required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on a contract’s size and risk profile. The initial margin deposit must then be maintained at an established level over the life of the contract. Amounts pledged, which are considered restricted, are included in cash pledged for futures contracts in the Statements of Assets and Liabilities.
Securities deposited as initial margin are designated in the Schedule of Investments and cash deposited, if any, are shown as cash pledged for futures contracts in the Statements of Assets and Liabilities. Pursuant to the contract, the Funds agree to receive from or pay to the broker an amount of cash equal to the daily fluctuation in market value of the contract (“variation margin”). Variation margin is recorded as unrealized appreciation (depreciation) and, if any, shown as variation margin receivable (or payable) on futures contracts in the Statements of Assets and Liabilities. When the contract is closed, a realized gain or loss is recorded in the Statements of Operations equal to the difference between the notional amount of the contract at the time it was opened and the notional amount at the time it was closed. The use of futures contracts involves the risk of an imperfect correlation in the movements in the price of futures contracts and interest rates, foreign currency exchange rates or underlying assets.
Forward Foreign Currency Exchange Contracts: Forward foreign currency exchange contracts are entered into to gain or reduce exposure to foreign currencies (foreign currency exchange rate risk).
A forward foreign currency exchange contract is an agreement between two parties to buy and sell a currency at a set exchange rate on a specified date. These contracts help to manage the overall exposure to the currencies in which some of the investments held by the Funds are denominated and in some cases, may be used to obtain exposure to a particular market.The contracts are traded over-the-counter (“OTC”) and not on an organized exchange.
The contract is marked-to-market daily and the change in market value is recorded as unrealized appreciation or depreciation in the Statements of Assets and Liabilities. When the contract is closed, a realized gain or loss is recorded in the Statements of Operations equal to the difference between the value at the time it was opened and the value at the time it was closed. Non-deliverable forward foreign currency exchange contracts are settled with the counterparty in cash without the delivery of foreign currency. The use of forward foreign currency exchange contracts involves the risk that the value of a contract changes unfavorably due to movements in the value of the referenced foreign currencies, and such value may exceed the amount(s) reflected in the Statements of Assets and Liabilities. Cash amounts pledged for forward foreign currency exchange contracts are considered restricted and are included in cash pledged as collateral for OTC derivatives in the Statements of Assets and Liabilities. Afund’s risk of loss from counterparty credit risk on OTC derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund.
Options: The Funds may purchase and write call and put options to increase or decrease its exposure to the risks of underlying instruments, including equity risk, interest rate risk and/or commodity price risk and/or, in the case of options written, to generate gains from options premiums.
A call option gives the purchaser (holder) of the option the right (but not the obligation) to buy, and obligates the seller (writer) to sell (when the option is exercised) the underlying instrument at the exercise or strike price at any time or at a specified time during the option period. A put option gives the holder the right to sell and obligates the writer to buy the underlying instrument at the exercise or strike price at any time or at a specified time during the option period.
Premiums paid on options purchased and premiums received on options written, as well as the daily fluctuation in market value, are included in investments at value – unaffiliated and options written at value, respectively, in the Statements of Assets and Liabilities. When an instrument is purchased or sold through the exercise of an
Notes to Financial Statements

option,the premium is offset against the cost or proceeds of the underlying instrument. When an option expires, a realized gain or loss is recorded in the Statements of Operations to the extent of the premiums received or paid. When an option is closed or sold, a gain or loss is recorded in the Statements of Operations to the extent the cost of the closing transaction exceeds the premiums received or paid. When the Fund writes a call option, such option is typically “covered,” meaning that it holds the underlying instrument subject to being called by the option counterparty. When the Fund writes a put option, cash is segregated in an amount sufficient to cover the obligation. These amounts,which are considered restricted, are included in cash pledged as collateral for options written in the Statements of Assets and Liabilities.
• Swaptions – The Fund may purchase and write options on swaps (“swaptions”) primarily to preserve a return or spread on a particular investment or portion of the Fund's holdings, as a duration management technique or to protect against an increase in the price of securities it anticipates purchasing at a later date. The purchaser and writer of a swaption is buying or granting the right to enter into a previously agreed upon interest rate or credit default swap agreement (interest rate risk and/or credit risk) at any time before the expiration of the option.
• Interest rate — Interest rate caps and floors are entered into to gain or reduce exposure to interest rates (interest rate risk and/or other risk). Caps are agreements whereby one party agrees to make payments to the other, in return for a premium, to the extent that interest rate indexes exceed a specified rate, or“cap.” Floors are agreements whereby one party agrees to make payments to the other, in return for a premium, to the extent that interest rate indexes fall below a specified rate, or “floor.” The maximum potential amount of future payments that the Fund would be required to make under an interest rate cap would be the notional amount times the percentage increase in interest rates determined by the difference between the interest rate index current value and the value at the time the cap was entered into.
• Foreign currency options – The Fund may purchase and write foreign currency options, foreign currency futures and options on foreign currency futures to gain or reduce exposure to foreign currencies (foreign currency exchange rate risk). Foreign currency options give the purchaser the right to buy from or sell to the writer a foreign currency at any time before the expiration of the option.
In purchasing and writing options, the Fund bears the risk of an unfavorable change in the value of the underlying instrument or the risk that it may not be able to enter into a closing transaction due to an illiquid market. Exercise of a written option could result in the Fund purchasing or selling a security when it otherwise would not, or at a price different from the current market value.
Swaps: Swap contracts are entered into to manage exposure to issuers, markets and securities. Such contracts are agreements between the Funds and a counterparty to make periodic net payments on a specified notional amount or a net payment upon termination. Swap agreements are privately negotiated in the OTC market and may be entered into as a bilateral contract (“OTC swaps”) or centrally cleared (“centrally cleared swaps”).
For OTC swaps, any upfront premiums paid and any upfront fees received are shown as swap premiums paid and swap premiums received, respectively, in the Statements of Assets and Liabilities and amortized over the term of the contract. The daily fluctuation in market value is recorded as unrealized appreciation (depreciation) on OTC Swaps in the Statements of Assets and Liabilities. Payments received or paid are recorded in the Statements of Operations as realized gains or losses, respectively. When an OTC swap is terminated, a realized gain or loss is recorded in the Statements of Operations equal to the difference between the proceeds from (or cost of) the closing transaction and the Funds' basis in the contract, if any. Generally, the basis of the contract is the premium received or paid.
In a centrally cleared swap, immediately following execution of the swap agreement, the swap agreement is novated to a central counterparty (“CCP”) and the CCP becomes the Fund’s counterparty on the swap. Each Fund is required to interface with the CCP through a broker. Upon entering into a centrally cleared swap, each Fund is required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap. Securities deposited as initial margin are designated on the Schedule of Investments and cash deposited is shown as cash pledged for centrally cleared swaps on the Statements of Assets and Liabilities. Amounts pledged, which are considered restricted cash, are included in cash pledged for centrally cleared swaps in the Statements of Assets and Liabilities. Pursuant to the contract, each Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in market value of the contract (“variation margin”). Variation margin is recorded as unrealized appreciation (depreciation) and shown as variation margin receivable (or payable) on centrally cleared swaps in the Statements of Assets and Liabilities. Payments received from (paid to) the counterparty are amortized over the term of the contract and recorded as realized gains (losses) in the Statements of Operations, including those at termination.
Total return swaps are entered into by the iShares Flexible Income Active ETF and iShares Total Return Active ETF to obtain exposure to a security or market without owning such security or investing directly in such market or to exchange the risk/return of one security or market (e.g., fixed-income) with another security or market (e.g., equity or commodity prices) (equity risk, commodity price risk and/or interest rate risk).
Total return swaps are agreements in which there is an exchange of cash flows whereby one party commits to make payments based on the total return (distributions plus capital gains/losses) of an underlying instrument, or basket or underlying instruments, in exchange for fixed or floating rate interest payments. If the total return of the instruments or index underlying the transaction exceeds or falls short of the offsetting fixed or floating interest rate obligation, the Fund receives payment from or makes a payment to the counterparty.
Certain total return swaps are designed to function as a portfolio of direct investments in long and short equity positions. This means that the Fund has the ability to trade in and out of these long and short positions within the swap and will receive the economic benefits and risks equivalent to direct investment in these positions, subject to certain adjustments due to events related to the counterparty. Benefits and risks include capital appreciation (depreciation), corporate actions and dividends received and paid, all of which are reflected in the swap’s market value. The market value also includes interest charges and credits (“financing fees”) related to the notional values of the long and short positions and cash balances within the swap. These interest charges and credits are based on a specified benchmark rate plus or minus a specified spread determined based upon the country and/or currency of the positions in the portfolio.
173
2025 BlackRock Annual Financial Statements and Additional Information

Notes to Financial Statements  (continued)
Positions within the swap and financing fees are reset periodically. During a reset, any unrealized appreciation (depreciation) on positions and accrued financing fees become available for cash settlement between the Fund and the counterparty. The amounts that are available for cash settlement are recorded as realized gains or losses in the Statements of Operations. Cash settlement in and out of the swap may occur at a reset date or any other date, at the discretion of the Fund and the counterparty, over the life of the agreement. Certain swaps have no stated expiration and can be terminated by either party at any time.
Interest rate swaps are entered into to gain or reduce exposure to interest rates or to manage duration, the yield curve or interest rate (interest rate risk).
Interest rate swaps are agreements in which one party pays a stream of interest payments, either fixed or floating, in exchange for another party’s stream of interest payments, either fixed or floating, on the same notional amount for a specified period of time. In more complex interest rate swaps, the notional principal amount may decline (or amortize) over time.
Swap transactions involve, to varying degrees, elements of interest rate, credit and market risks in excess of the amounts recognized in the Statements of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in interest rates and/or market values associated with these transactions.
Master Netting Arrangements: In order to define its contractual rights and to secure rights that will help mitigate its counterparty risk, a Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement with its derivative contract counterparties. An ISDA Master Agreement is a bilateral agreement between a Fund and a counterparty that governs certain OTC derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, a Fund may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default including the bankruptcy or insolvency of the counterparty. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency, or other events.
For derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the mark-to-market amount for each transaction under such agreement, and comparing that amount to the value of any collateral currently pledged by a fund and the counterparty. 
Cash collateral that has been pledged to cover obligations of the Funds and cash collateral received from the counterparty, if any, is reported separately in the Statements of Assets and Liabilities as cash pledged as collateral and cash received as collateral, respectively. Non-cash collateral pledged by the Funds, if any, is noted in the Schedules of Investments. Generally, the amount of collateral due from or to a counterparty is subject to a certain minimum transfer amount threshold before a transfer is required, which is determined at the close of business of the Funds. Any additional required collateral is delivered to/pledged by the Funds on the next business day. Typically, the counterparty is not permitted to sell, re-pledge or use cash and non-cash collateral it receives.Afund generally agrees not to use non-cash collateral that it receives butmay, absent default or certain other circumstances defined in the underlying ISDA Master Agreement, be permitted to use cash collateral received. In such cases, interest may be paid pursuant to the collateral arrangement with the counterparty. To the extent amounts due to the Funds from the counterparty are not fully collateralized, each Fund bears the risk of loss from counterparty non-performance. Likewise, to the extent the Funds have delivered collateral to a counterparty and stand ready to perform under the terms of their agreement with such counterparty, each Fund bears the risk of loss from a counterparty in the amount of the value of the collateral in the event the counterparty fails to return such collateral. Based on the terms of agreements, collateral may not be required for all derivative contracts.
For financial reporting purposes, each Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements, if any, in the Statements of Assets and Liabilities.

Notes to Financial Statements  (continued)
Distributor: BlackRock Investments, LLC ("BRIL"), an affiliate of BFA, is the distributor for each Fund. Pursuant to the distribution agreement, BFA is responsible for any fees or expenses for distribution services provided to the Funds.
ETFServicing Fees: Each Fund has entered into an ETF Services Agreement with BRIL to perform certain order processing, Authorized Participant communications, and related services in connection with the issuance and redemption of Creation Units (“ETF Services”). BRIL is entitled to a transaction fee from Authorized Participants on each creation or redemption order for the ETF Services provided. The Funds do not pay BRIL for ETF Services.
Securities Lending: The U.S. Securities and Exchange Commission (the "SEC") has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Funds, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to securities lending, including any custodial costs. Each Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan (the “collateral investment fees”). The cash collateral is invested in a money market fund, BlackRock Cash Funds: Institutional or BlackRock Cash Funds: Treasury, managed by BFA, or its affiliates. However, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees the Funds bear to an annual rate of 0.04%. The SLAgency Shares of such money market fund will not be subject to a sales load, distribution fee or service fee. BlackRock Cash Funds: Institutional may impose a discretionary liquidity fee of up to 2% on all redemptions. Discretionary liquidity fees may be imposed or terminated at any time at the discretion of the board of directors of the money market fund, or its delegate, if it is determined that such fee would be, or would not be, respectively, in the best interest of the money market fund. Additionally, BlackRock Cash Funds: Institutional will impose a mandatory liquidity fee if the money market fund's total net redemptions on a single day exceed 5% of the money market fund's net assets, unless the amount of the fee is less than 0.01% of the value of the shares redeemed. BlackRock Cash Funds: Institutional will determine the size of the mandatory liquidity fee by making a good faith estimate of certain costs the money market fund would incur if it were to sell a pro rata amount of each security in the portfolio to satisfy the amount of net redemptions on that day. There is no limit to the size of a mandatory liquidity fee.  If BlackRock Cash Funds: Institutional cannot estimate the costs of selling a pro rata amount of each portfolio security in good faith and supported by data, it is required to apply a default liquidity fee of 1% on the value of shares redeemed on that day.
Securities lending income is generally equal to the total of income earned from the reinvestment of cash collateral (and excludes collateral investment fees), and any fees or other payments to and from borrowers of securities. Each Fund retains a portion of the securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent.
Pursuant to the current securities lending agreement, each Fund retains 82% of securities lending income (which excludes collateral investment fees) and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.
In addition, commencing the business day following the date that the aggregate securities lending income plus the collateral investment fees generated across the BlackRock Fixed-Income Complex in that calendar year exceeds a specified threshold, each Fund, pursuant to the securities lending agreement, will retain for the remainder of that calendar year 85% of securities lending income (which excludes collateral investment fees), and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.
The share of securities lending income earned by each Fund is shown as securities lending income – affiliated – net in its Statements of Operations. For the year ended July 31, 2025, the Funds paid BTC the following amounts for securities lending agent services:

Each Fund is treated as an entity separate from the Trust’s other funds for federal income tax purposes.  It is each Fund’s policy to comply with the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute substantially all of its taxable income to its shareholders. Therefore, no U.S. federal income tax provision is required.
Management has analyzed tax laws and regulations and their application to the Funds as of July 31, 2025, inclusive of the open tax return years, and does not believe that there are any uncertain tax positions that require recognition of a tax liability in the Funds’ financial statements. Management’s analysis is based on the tax laws and judicial and administrative interpretations thereof in effect as of the date of these financial statements, all of which are subject to change, possibly with retroactive effect, which may impact the Funds’ NAV.
U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting.  These reclassifications have no effect on net assets or NAV per share. As of July 31, 2025, permanent differences attributable to distributions in connection with fund share redemptions were reclassified to the following accounts:

9. LINE OFCREDIT
The Trust, on behalf of the Funds, along with certain other funds managed by the Manager and its affiliates (“Participating Funds”), is party to a 364-day, $2.40 billion credit agreement with a group of lenders. Under this agreement, the Funds may borrow to fund shareholder redemptions. Excluding commitments designated for certain individual funds, the Participating Funds, including the Funds, can borrow up to an aggregate commitment amount of $1.75 billion at any time outstanding, subject to asset coverage and other limitations as specified in the agreement. With respect to Floating Rate Loan, of the aggregate $2.40 billion commitment amount, $650 million is specifically designated to the Fund and another participating Fund. The remaining $1.75 billion commitment is available to all Participating Funds, but Floating Rate Loan can borrow up to an additional $350 million in the aggregate of the remaining aggregate commitment, subject to asset coverage and other limitations as specified in the agreement. The credit agreement has the following terms: a fee of 0.10% per annum on unused commitment amounts and interest at a rate equal to the higher of (a) Overnight Bank Funding Rate (“OBFR”) (but in any event, not less than 0.00%) on the date the loan is made plus 0.80% per annum, (b) the Fed Funds rate (but in any event, not less than 0.00%) in effect from time to time plus 0.80% per annum on amounts borrowed or (c) the sum of (x) Daily Simple SOFR (but, in any event, not less than 0.00%) on the date the loan is made plus 0.10% and (y) 0.80% per annum . The agreement expires in April 2026 unless extended or renewed.  Floating Rate Loan paid an upfront commitment fee of 0.04% on new commitments of $250 million, in addition to administration, legal and arrangement fees, which are included in miscellaneous expenses in the Statements of Operations. These fees were allocated among such funds based upon portions of the aggregate commitment available to them and relative net assets of Participating Funds. During the year ended July 31, 2025, the Funds did not borrow under the credit agreement.
10. PRINCIPAL RISKS
In the normal course of business, each Fund invests in securities or other instruments and may enter into certain transactions, and such activities subject each Fund to various risks, including, among others, fluctuations in the market (market risk) or failure of an issuer to meet all of its obligations. The value of securities or other instruments may also be affected by various factors, including, without limitation: (i) the general economy; (ii) the overall market as well as local, regional or global political and/or social instability; (iii) regulation, taxation, tariffs or international tax treaties between various countries; or (iv) currency, interest rate or price fluctuations.  Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the Funds and their investments. Each Fund’s prospectus provides details of the risks to which the Fund is subject.
The Funds may be exposed to additional risks when reinvesting cash collateral in money market funds that do not seek to maintain a stable NAV per share of $1.00, which may be subject to mandatory and discretionary liquidity fees under certain circumstances.
Market Risk: Each Fund may be exposed to prepayment risk, which is the risk that borrowers may exercise their option to prepay principal earlier than scheduled during periods of declining interest rates, which would force each Fund to reinvest in lower yielding securities. Each Fund may also be exposed to reinvestment risk, which is the risk that income from each Fund’s portfolio will decline if each Fund invests the proceeds from matured, traded or called fixed-income securities at market interest rates that are below each Fund portfolio’s current earnings rate.
Municipal securities are subject to the risk that litigation, legislation or other political events, local business or economic conditions, credit rating downgrades, or the bankruptcy of the issuer could have a significant effect on an issuer’s ability to make payments of principal and/or interest or otherwise affect the value of such securities. Municipal securities can be significantly affected by political or economic changes, including changes made in the law after issuance of the securities, as well as uncertainties in the municipal market related to, taxation, legislative changes or the rights of municipal security holders, including in connection with an issuer insolvency. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the tax benefits supporting the project or assets or the inability to collect revenues for the project or from the assets. Municipal securities may be less liquid than taxable bonds, and there may be less publicly available information on the financial condition of municipal security issuers than for issuers of other securities.
Valuation Risk: The market values of equities, such as common stocks and preferred securities or equity related investments, such as futures and options, may decline due to general market conditions which are not specifically related to a particular company. They may also decline due to factors which affect a particular industry or industries. AFund may invest in illiquid investments. An illiquid investment is any investment that a Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. AFund may experience difficulty in selling illiquid investments in a timely manner at the price that it believes the investments are worth. Prices may fluctuate widely over short or extended periods in response to
179
2025 BlackRock Annual Financial Statements and Additional Information

Notes to Financial Statements  (continued)
company, market or economic news. Markets also tend to move in cycles, with periods of rising and falling prices. This volatility may cause each Fund’s NAV to experience significant increases or decreases over short periods of time. If there is a general decline in the securities and other markets, the NAV of a Fund may lose value, regardless of the individual results of the securities and other instruments in which a Fund invests. A Fund’s ability to value its investments may also be impacted by technological issues and/or errors by pricing services or other third-party service providers.
The price each Fund could receive upon the sale of any particular portfolio investment may differ from each Fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair valuation technique or a price provided by an independent pricing service. Changes to significant unobservable inputs and assumptions (i.e., publicly traded company multiples, growth rate, time to exit) due to the lack of observable inputs may significantly impact the resulting fair value and therefore each Fund’s results of operations. As a result, the price received upon the sale of an investment may be less than the value ascribed by each Fund, and each Fund could realize a greater than expected loss or lesser than expected gain upon the sale of the investment.
Counterparty Credit Risk: The Funds may be exposed to counterparty credit risk, or the risk that an entity may fail to or be unable to perform on its commitments related to unsettled or open transactions, including making timely interest and/or principal payments or otherwise honoring its obligations. The Funds manage counterparty credit risk by entering into transactions only with counterparties that BFA believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the Funds to market, issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of the Funds’ exposure to market, issuer and counterparty credit risks with respect to these financial assets is approximately their value recorded in the Statements of Assets and Liabilities, less any collateral held by the Funds.
A derivative contract may suffer a mark-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract.
With exchange-traded futures and centrally cleared swaps, there is less counterparty credit risk to the Funds since the exchange or clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, credit risk is limited to failure of the clearinghouse. While offset rights may exist under applicable law, a Fund does not have a contractual right of offset against a clearing broker or clearinghouse in the event of a default (including the bankruptcy or insolvency).Additionally, credit risk exists in exchange-traded futures and centrally cleared swaps with respect to initial and variation margin that is held in a clearing broker’s customer accounts. While clearing brokers are required to segregate customer margin from their own assets, in the event that a clearing broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the clearing broker for all its clients, typically the shortfall would be allocated on a pro rata basis across all the clearing broker’s customers, potentially resulting in losses to the Funds.
Geographic/Asset Class Risk: Adiversified portfolio, where this is appropriate and consistent with a fund’s objectives, minimizes the risk that a price change of a particular investment will have a material impact on the NAV of a fund. The investment concentrations within each Fund’s portfolio are disclosed in its Schedule of Investments.
The Funds invest a significant portion of their assets in securities of issuers located in the United States. A decrease in imports or exports, changes in trade regulations, inflation and/or an economic recession in the United States may have a material adverse effect on the U.S. economy and the securities listed on U.S. exchanges. Proposed and adopted policy and legislative changes in the United States may also have a significant effect on U.S. markets generally, as well as on the value of certain securities. Governmental agencies project that the United States will continue to maintain elevated public debt levels for the foreseeable future which may constrain future economic growth. Circumstances could arise that could prevent the timely payment of interest or principal on U.S. government debt, such as reaching the legislative “debt ceiling.” Such non-payment would result in substantial negative consequences for the U.S. economy and the global financial system. If U.S. relations with certain countries deteriorate, it could adversely affect issuers that rely on the United States for trade. The United States has also experienced increased internal unrest and discord. If these trends were to continue, they may have an adverse impact on the U.S. economy and the issuers in which the Funds invest.
Certain Funds invest a significant portion of their assets in issuers located in a single state or limited number of states, When a fund concentrates its investments in this manner, it assumes the risk that economic, regulatory, political or social conditions affecting that state or group of states could have a significant impact on the fund and could affect the income from, or the value or liquidity of, the fund’s portfolio. Investment percentages in specific states or U.S. territories are presented in the Schedule of Investments.
Certain Funds invest a significant portion of their assets in high yield securities. High yield securities that are rated below investment-grade (commonly referred to as “junk bonds”) or are unrated may be deemed speculative, involve greater levels of risk than higher-rated securities of similar maturity and are more likely to default. High yield securities may be issued by less creditworthy issuers, and issuers of high yield securities may be unable to meet their interest or principal payment obligations. High yield securities are subject to extreme price fluctuations, may be less liquid than higher rated fixed-income securities, even under normal economic conditions, and frequently have redemption features.
The Funds invest a significant portion of their assets in fixed-income securities and/or use derivatives tied to the fixed-income markets. Changes in market interest rates or economic conditions may affect the value and/or liquidity of such investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will decrease as interest rates rise and increase as interest rates fall. The Funds may be subject to a greater risk of rising interest rates during a period of historically low interest rates. Changing interest rates may have unpredictable effects on markets, may result in heightened market volatility, and could negatively impact the Funds’ performance.
The risks of investing in CLOs depend largely on the type of the collateral securities and the tranche of the CLO. In stressed market conditions, it is possible that even senior CLO debt tranches, such as those in which certain Funds  invest, could experience losses due to actual defaults, downgrades of the underlying collateral by rating agencies, forced liquidation of the collateral pool due to a failure of coverage tests, increased sensitivity to defaults due to collateral default and the disappearance of protecting tranches, market anticipation of defaults as well as investor aversion to CLO securities as an asset class. While certain Funds invest principally in CLO tranches that are
Notes to Financial Statements
180

Notes to Financial Statements  (continued)
rated BBB-B, such ratings do not constitute a guarantee of credit quality and may be downgraded. To the extent certain Funds invest in CLO tranches rated below BBB-B, the risks of investing in CLOs will be greater.
CLOs, and their underlying loan obligations, are typically not registered for sale to the public and therefore are subject to certain restrictions on transfer and sale, potentially making them less liquid than other types of securities. Some unrated CLO securities may not have an active trading market or may be difficult to value. As a result, proceeds from the sale of CLO securities may not be readily available to make additional investments or to meet certain Funds’ redemption obligations. During periods of limited liquidity and higher price volatility, certain Funds’ ability to acquire or dispose of CLO securities at a price and time such Funds deem advantageous may be impaired.
Significant Shareholder Redemption Risk: Certain shareholders may own or manage a substantial amount of fund shares and/or hold their fund investments for a limited period of time. Large redemptions of fund shares by these shareholders may force a fund to sell portfolio securities, which may negatively impact the fund’s NAV, increase the fund’s brokerage costs, and/or accelerate the realization of taxable income/gains and cause the fund to make additional taxable distributions to shareholders.

The consideration for the purchase of Creation Units of a fund in the Trust generally consists of the in-kind deposit of a designated portfolio of securities and a specified amount of cash. Certain funds in the Trust may be offered in Creation Units solely or partially for cash in U.S. dollars. Authorized Participants purchasing and redeeming Creation Units may pay a purchase transaction fee and a redemption transaction fee directly to State Street Bank and Trust Company, the Trust’s administrator or BRIL, to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units, including Creation Units for cash. Authorized Participants transacting in Creation Units for cash may also pay an additional variable charge to compensate the relevant fund for certain transaction costs (i.e., stamp taxes, taxes on currency or other financial transactions, and brokerage costs) and market impact expenses relating to investing in portfolio securities. Such variable charges, if any, are included in shares sold in the table above.
To the extent applicable, to facilitate the timely settlement of orders for the Funds using a clearing facility outside of the continuous net settlement process, the Funds, at their sole discretion, may permit an Authorized Participant to post cash as collateral in anticipation of the delivery of all or a portion of the applicable Deposit Securities or Fund Securities, as further described in the applicable Authorized Participant Agreement. The collateral process is subject to a Control Agreement among the Authorized Participant, each Fund’s custodian, and the Funds. In the event that the Authorized Participant fails to deliver all or a portion of the applicable Deposit Securities or Fund Securities, the Fund may exercise control over such collateral pursuant to the terms of the Control Agreement in order to purchase the applicable Deposit Securities or Fund Securities.
From time to time, settlement of securities related to in-kind contributions or in-kind redemptions may be delayed. In such cases, securities related to in-kind transactions are reflected as a receivable or a payable in the Statements of Assets and Liabilities.

Basis for Opinions
These financial statements are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. 
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of July 31, 2025 by correspondence with the custodian, transfer agent, agent banks and brokers; when replies were not received from agent banks and brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

2025 BlackRock Annual Financial Statements and Additional Information

Disclosure of Investment Advisory Agreement and Sub-Advisory Agreements
The Board of Trustees (the “Board,” the members of which are referred to as “Board Members”) of BlackRock ETF Trust II (the “Trust”) met on May 8, 2025 (the “May Meeting”) and June 5-6, 2025 (the “June Meeting”) to consider the approval to continue the investment advisory agreement (the “Advisory Agreement”) between the Trust, on behalf of iShares AAA CLO Active ETF (“CLOA”), iShares Flexible Income Active ETF (“BINC”), iShares Floating Rate Loan Active ETF (“BRLN”), iShares Intermediate Muni Income Active ETF (“INMU”), iShares Short Duration High Yield Muni Active ETF (“SHYM”), iShares Short-Term California Muni Active ETF (“CALI”) and iShares Total Return Active ETF (“BRTR” and collectively with CLOA, BINC, BRLN, INMU, SHYM and CALI, the “Funds” and each, a “Fund”), and BlackRock Fund Advisors (the “Manager”), each Fund’s investment advisor. The Board also considered the approval to continue the sub-advisory agreements (the “Sub-Advisory Agreements”) between (1) the Manager and BlackRock International Limited (“BIL”), with respect to BINC and BRTR, and (2) BlackRock (Singapore) Limited (“BSL” and together with BIL, the “Sub-Advisors”), with respect to BINC and BRTR. The Manager and the Sub-Advisors are referred to herein as “BlackRock.” The Advisory Agreement and the Sub-Advisory Agreements are referred to herein as the “Agreements.”
The Approval Process
Consistent with the requirements of the Investment Company Act of 1940 (the “1940 Act”), the Board considers the approval of the continuation of the Agreements for each Fund on an annual basis. The Board Members who are not “interested persons” of the Trust, as defined in the 1940 Act, are considered independent Board Members (the “Independent Board Members”). The Board’s consideration entailed a year-long deliberative process during which the Board and its committees assessed BlackRock’s various services to each Fund, including through the review of written materials and oral presentations, and the review of additional information provided in response to requests from the Independent Board Members. The Board had four quarterly meetings per year, as well as numerous ad hoc meetings and executive sessions throughout the year, as needed. The committees of the Board similarly met throughout the year. The Board also held the May Meeting to consider specific information regarding the renewal of the Agreements. In considering the renewal of the Agreements, the Board assessed, among other things, the nature, extent and quality of the services provided to each Fund by BlackRock, BlackRock’s personnel and affiliates, including (as applicable): investment management services; accounting oversight; administrative and shareholder services; oversight of each Fund’s service providers; risk management and oversight; and legal, regulatory and compliance services. Throughout the year, including during the contract renewal process, the Independent Board Members were advised by independent legal counsel, and met with independent legal counsel in various executive sessions outside of the presence of BlackRock’s management.
During the year, the Board, acting directly and through its committees, considered information that was relevant to its annual consideration of the renewal of the Agreements, including the services and support provided by BlackRock to each Fund and its shareholders. BlackRock also furnished additional information to the Board in response to specific questions from the Board. Among the matters the Board considered were:  (a) investment performance for one-year, three-year, five-year, and/or since inception periods, as applicable, against peer funds, relevant benchmarks, and other performance metrics, as applicable, as well as BlackRock senior management’s and portfolio managers’ investment performance analyses, and the reasons for any outperformance or underperformance relative to its peers, benchmarks, and other performance metrics, as applicable; (b) fees, including advisory, administration, if applicable, and other amounts paid to BlackRock and its affiliates by each Fund for services; (c) Fund operating expenses and how BlackRock allocates expenses to each Fund; (d) the resources devoted to, risk oversight of, and compliance reports relating to, implementation of each Fund’s investment objective, policies and restrictions, and meeting regulatory requirements; (e) BlackRock’s and each Fund’s adherence to applicable compliance policies and procedures; (f) the nature, character and scope of non-investment management services provided by BlackRock and its affiliates and the estimated cost of such services, as applicable; (g) BlackRock’s and other service providers’ internal controls and risk and compliance oversight mechanisms; (h) BlackRock’s implementation of the proxy voting policies approved by the Board; (i) execution quality of portfolio transactions; (j) BlackRock’s implementation of each Fund’s valuation and liquidity procedures; (k) an analysis of management fees paid to BlackRock for products with similar investment mandates across the open-end fund, exchange-traded fund (“ETF”), closed-end fund, sub-advised mutual fund, separately managed account, collective investment trust, and institutional separate account product channels, as applicable, and the similarities and differences between these products and the services provided as compared to each Fund; (l) BlackRock’s compensation methodology for its investment professionals and the incentives and accountability it creates, along with investment professionals’ investments in the fund(s) they manage; and (m) periodic updates on BlackRock’s business.
Prior to and in preparation for the May Meeting, the Board received and reviewed materials specifically relating to the renewal of the Agreements. The Independent Board Members continuously engaged in a process with their independent legal counsel and BlackRock to review the nature and scope of the information provided to the Board to better assist its deliberations. The materials provided in connection with the May Meeting included, among other things: (a) information independently compiled and prepared by Broadridge Financial Solutions, Inc. (“Broadridge”), based on either a Lipper classification or Morningstar category, regarding each Fund’s fees and expenses as compared with a peer group of funds as determined by Broadridge (“Expense Peers”) and the investment performance of each Fund as compared with a peer group of funds (“Performance Peers”); (b) information on the composition of the Expense Peers and Performance Peers and a description of Broadridge’s methodology; (c) information on the estimated profits realized by BlackRock and its affiliates pursuant to the Agreements and a discussion of fall-out benefits to BlackRock and its affiliates; (d) a general analysis provided by BlackRock concerning investment management fees received in connection with other types of investment products, such as institutional accounts, sub-advised mutual funds, ETFs, closed-end funds, open-end funds, and separately managed accounts, under similar investment mandates, as well as the performance of such other products, as applicable; (e) a review of non-management fees; (f) the existence, impact and sharing of potential economies of scale, if any, with each Fund; (g) a summary of aggregate amounts paid by each Fund to BlackRock; (h) sales and redemption data regarding each Fund’s shares; and (i) various additional information requested by the Board as appropriate regarding BlackRock’s and each Fund’s operations.
At the May Meeting, the Board reviewed materials relating to its consideration of the Agreements and the Independent Board Members presented BlackRock with questions and requests for additional information. BlackRock responded to these questions and requests with additional written information in advance of the June Meeting, and such responses were reviewed by the Board Members.
At the June Meeting, the Board concluded its assessment of, among other things: (a) the nature, extent and quality of the services provided by BlackRock; (b) the investment performance of each Fund as compared to its Performance Peers and to other metrics, as applicable; (c) the advisory fee and the estimated cost of the services and estimated profits realized by BlackRock and its affiliates from their relationship with each Fund; (d) each Fund’s fees and expenses compared to its Expense Peers; (e) the

Disclosure of Investment Advisory Agreement and Sub-Advisory Agreements  (continued)
existence and sharing of potential economies of scale; (f) any fall-out benefits to BlackRock and its affiliates as a result of BlackRock’s relationship with each Fund; and (g) other factors deemed relevant by the Board Members.
The Board also considered other matters it deemed important to the approval process, such as other payments made to BlackRock or its affiliates relating to securities lending and cash management, and BlackRock’s services related to the valuation and pricing of Fund portfolio holdings. The Board noted the willingness of BlackRock’s personnel to engage in open, candid discussions with the Board. The Board evaluated the information available to it on a fund-by-fund basis. The following paragraphs provide more information about some of the primary factors that were relevant to the Board’s decision. The Board Members did not identify any particular information, or any single factor as determinative, and each Board Member may have attributed different weights to the various items and factors considered.
A. Nature, Extent and Quality of the Services Provided by BlackRock
The Board, including the Independent Board Members, reviewed the nature, extent and quality of services provided by BlackRock, including the investment advisory services, and the resulting performance of each Fund. Throughout the year, the Board compared Fund performance to the performance of a comparable group of mutual funds, relevant benchmarks, and performance metrics, as applicable. The Board met with BlackRock’s senior management personnel responsible for investment activities, including the senior investment officers. The Board also reviewed the materials provided by each Fund’s portfolio management team discussing each Fund’s performance, investment strategies and outlook.
The Board considered, among other factors, with respect to BlackRock: the experience of each Fund’s portfolio management team; research capabilities; investments by portfolio managers in the funds they manage; portfolio trading capabilities; use of certain trading, portfolio management, operations and/or information systems owned by BlackRock; commitment to compliance; credit analysis capabilities; risk analysis and oversight capabilities; and the approach to training and retaining portfolio managers and other research, advisory and management personnel. The Board also considered BlackRock’s overall risk management program, including the continued efforts of BlackRock and its affiliates to address cybersecurity risks and the role of BlackRock’s Risk & Quantitative Analysis Group. The Board engaged in a review of BlackRock’s compensation structure with respect to each Fund’s portfolio management team and BlackRock’s ability to attract and retain high-quality talent and create performance incentives.
In addition to investment advisory services, the Board considered the nature and quality of the administrative and other non-investment advisory services provided to each Fund. BlackRock and its affiliates provide each Fund with certain administrative, shareholder and other services (in addition to any such services provided to each Fund by third parties) and officers and other personnel as are necessary for the operations of each Fund. In particular, BlackRock and its affiliates provide each Fund with administrative services including, among others: (i) responsibility for disclosure documents, such as the prospectus, the summary prospectus (as applicable), the statement of additional information and periodic shareholder reports; (ii) oversight of daily accounting and pricing; (iii) responsibility for periodic filings with regulators; (iv) overseeing and coordinating the activities of third-party service providers including, among others, each Fund’s custodian, fund accountant, transfer agent, and auditor; (v) organizing Board meetings and preparing the materials for such Board meetings; (vi) providing legal and compliance support; (vii) furnishing analytical and other support to assist the Board in its consideration of strategic issues such as the merger, consolidation or repurposing of certain open-end funds; and (viii) performing or managing administrative functions necessary for the operation of each Fund, such as tax reporting, expense management, fulfilling regulatory filing requirements, overseeing each Fund’s distribution partners, and shareholder call center and other services. The Board reviewed the structure and duties of BlackRock’s fund administration, shareholder services, and legal and compliance departments and considered BlackRock’s policies and procedures for assuring compliance with applicable laws and regulations. The Board also considered the operation of BlackRock’s business continuity plans.
The Board noted that the engagement of the Sub-Advisors with respect to BINC and BRTR facilitates the provision of investment advice and trading by investment personnel out of non-U.S. jurisdictions. The Board considered that this arrangement provides additional flexibility to the portfolio management team, which may benefit each of BINC and BRTR and its shareholders.
B. The Investment Performance of each Fund
The Board, including the Independent Board Members, reviewed and considered the performance history of each Fund throughout the year and at the May Meeting. The Board was provided with Fund performance reporting and analysis, relative to applicable performance metrics, by BlackRock throughout the year and at the May Meeting. In preparation for the May Meeting, the Board was also provided with reports independently prepared by Broadridge, which included an analysis of each Fund’s performance as of December 31, 2024, as compared to its Performance Peers. Broadridge ranks funds in quartiles, ranging from first to fourth, where first is the most desirable quartile position and fourth is the least desirable. In connection with its review, the Board received and reviewed information regarding the investment performance of each Fund as compared to its Performance Peers. The Board and its Performance Oversight Committee regularly review and meet with Fund management to discuss the performance of each Fund throughout the year.
The Board also noted that while it found the data provided by Broadridge generally useful, it recognized the limitations of such data, including in particular, that notable differences may exist between a fund and its Performance Peers (for example, the investment objectives and strategies). Further, the Board recognized that the performance data reflects a snapshot of a period as of a particular date and that selecting a different performance period could produce significantly different results. The Board also acknowledged that long-term performance could be impacted by even one period of significant outperformance or underperformance, and that a single investment theme could have the ability to disproportionately affect long-term performance.
The Board noted that for each of the one-year and since-inception periods reported, CLOA ranked in the first quartile against its Performance Peers.
The Board noted that for each of the one-year and since-inception periods reported, BINC ranked in the second quartile against its Performance Peers.
187
2025 BlackRock Annual Financial Statements and Additional Information

Disclosure of Investment Advisory Agreement and Sub-Advisory Agreements  (continued)
The Board noted that for the one-year and since-inception periods reported, BRLN ranked in the third and second quartiles, respectively, against its Performance Peers. The Board and BlackRock reviewed BRLN’s underperformance relative to its Performance Peers during the applicable period.
The Board noted that for each of the one-year, three-year and since-inception periods reported, INMU ranked in the first quartile against its Performance Peers.
The Board noted that for the one-year, three-year and since-inception periods reported, SHYM ranked in the first, second and first quartiles, respectively, against its Performance Peers. The Board also noted that the Fund has undergone certain changes in investment strategy, and in connection with such changes, the Fund had changed its name from the iShares High Yield Muni Income Active ETF to the iShares Short Duration High Yield Muni Active ETF effective on or about June 30, 2025.
The Board noted that for each of the one-year and since-inception periods reported, CALI ranked in the first quartile against its Performance Peers.
The Board noted that for each of the one-year and since-inception periods reported, BRTR ranked in the fourth quartile against its Performance Peers. The Board and BlackRock reviewed BRTR’s underperformance relative to its Performance Peers during the applicable periods.
C. Consideration of the Advisory/Management Fees and the Estimated Cost of the Services and Estimated Profits Realized by BlackRock and its Affiliates from their Relationship with each Fund
The Board, including the Independent Board Members, reviewed each Fund’s contractual management fee rate compared with those of its Expense Peers. The contractual management fee rate represents a combination of the advisory fee and any administrative fees, before taking into account any reimbursements or fee waivers. The Board also compared each Fund’s total expense ratio, as well as its actual management fee rate, to those of its Expense Peers. The total expense ratio represents a fund’s total net operating expenses, including any 12b-1 or non-12b-1 service fees. The total expense ratio gives effect to any expense reimbursements or fee waivers, and the actual management fee rate gives effect to any management fee reimbursements or waivers. The Board considered that the fee and expense information in the Broadridge report for each Fund reflected information for a specific period and that historical asset levels and expenses may differ from current levels, particularly in a period of market volatility. The Board also noted that while it found the expense comparison provided by Broadridge generally useful, it recognized that the comparison is subject to Broadridge’s defined peer selection criteria and methodology. The Board considered the services provided and the fees charged by BlackRock and its affiliates to other types of clients with similar investment mandates, as applicable, including institutional accounts and sub-advised mutual funds (including mutual funds sponsored by third parties).
The Board reviewed BlackRock’s profitability methodology and was also provided with an estimated profitability analysis that detailed the revenues earned and the expenses incurred by BlackRock for services provided to each Fund. The Board reviewed BlackRock’s estimated profitability with respect to each Fund and other funds the Board currently oversees for the year ended December 31, 2024 compared to available aggregate estimated profitability data provided for the prior two years. The Board reviewed BlackRock’s estimated profitability with respect to certain other U.S. fund complexes managed by the Manager and/or its affiliates. The Board reviewed BlackRock’s assumptions and methodology of allocating expenses in the estimated profitability analysis, noting the inherent limitations in allocating costs among various advisory products. The Board recognized that profitability may be affected by numerous factors including, among other things, fee waivers and expense reimbursements by the Manager, the types of funds managed, precision of expense allocations and business mix. The Board thus recognized the limitations of calculating and comparing profitability at the individual fund level.
The Board received and reviewed statements relating to BlackRock’s financial condition. The Board reviewed BlackRock’s overall operating margin, in general, compared to that of certain other publicly traded asset management firms. The Board considered the differences between BlackRock and these other firms, including the contribution of BlackRock’s technology business, BlackRock’s expense management, and the relative product mix. The Board noted that, in general, individual fund or product line profitability of other advisors is not publicly available.
The Board considered whether BlackRock has the financial resources necessary to attract and retain high quality investment management personnel to perform its obligations under the Agreements and to continue to provide the high quality of services that is expected by the Board. The Board further considered factors including but not limited to BlackRock’s commitment of time and resources, assumption of risk, and liability profile in servicing each Fund, including in contrast to what is required of BlackRock with respect to other products with similar investment mandates across the open-end fund, ETF, closed-end fund, sub-advised mutual fund, separately managed account, collective investment trust, and institutional separate account product channels, as applicable.
The Board noted that CLOA’s contractual management fee rate ranked in the first quartile, and that the actual management fee rate and total expense ratio each ranked in the first quartile relative to CLOA’s Expense Peers.
The Board noted that BINC’s contractual management fee rate ranked in the third quartile, and that the actual management fee rate and total expense ratio each ranked in the first quartile relative to BINC’s Expense Peers. The Board further noted that BlackRock had contractually agreed to waive a portion of the advisory fee payable by BINC.
The Board noted that BRLN’s contractual management fee rate ranked in the second quartile, and that the actual management fee rate and total expense ratio each ranked in the first quartile relative to BRLN’s Expense Peers. The Board also noted that BlackRock had contractually agreed to waive a portion of the advisory fee payable by BRLN.
The Board noted that INMU’s contractual management fee rate ranked in the first quartile, and that the actual management fee rate and total expense ratio each ranked in the second quartile relative to INMU’s Expense Peers. The Board also noted that BlackRock had contractually agreed to waive a portion of the advisory fee payable by INMU.
The Board noted that SHYM’s contractual management fee rate ranked in the second quartile, and that the actual management fee rate and total expense ratio each ranked in the second quartile relative to SHYM’s Expense Peers. The Board also noted that BlackRock had contractually agreed to waive a portion of the advisory fee payable by SHYM.
Disclosure of Investment Advisory Agreement

Disclosure of Investment Advisory Agreement and Sub-Advisory Agreements  (continued)
The Board noted that CALI’s contractual management fee rate ranked in the second quartile, and that the actual management fee rate and total expense ratio each ranked in the second quartile relative to CALI’s Expense Peers. The Board also noted that BlackRock had contractually agreed to waive a portion of the advisory fee payable by CALI.
The Board noted that BRTR’s contractual management fee rate ranked in the second quartile, and that the actual management fee rate and total expense ratio each ranked in the third quartile relative to BRTR’s Expense Peers. The Board also noted that BRTR has an advisory fee arrangement that includes breakpoints that adjust the fee rate downward as the size of BRTR increases above certain contractually specified levels. The Board additionally noted that the breakpoints can, conversely, adjust the advisory fee rate upward as the size of BRTR decreases below certain contractually specified levels. The Board further noted that BlackRock had contractually agreed to waive a portion of the advisory fee payable by BRTR.
D. Economies of Scale
The Board, including the Independent Board Members, considered the extent to which any economies of scale might benefit each Fund in a variety of ways as the assets of each Fund increase. The Board considered multiple factors, including the advisory fee rate and breakpoints, unitary fee structure, fee waivers, and/or expense caps, as applicable. The Board considered each Fund’s asset levels and whether the current fee schedule was appropriate.
E. Other Factors Deemed Relevant by the Board Members
The Board, including the Independent Board Members, also took into account other ancillary or “fall-out” benefits that BlackRock or its affiliates may derive from BlackRock’s respective relationships with each Fund, both tangible and intangible, such as BlackRock’s ability to leverage its investment professionals who manage other portfolios and its risk management personnel, an increase in BlackRock’s profile in the investment advisory community, and the engagement of BlackRock’s affiliates as service providers to each Fund, including for administrative, distribution, securities lending, ETF servicing and cash management services. With respect to securities lending, during the year the Board also considered information provided by independent third-party consultants related to the performance of each BlackRock affiliate as securities lending agent. The Board also considered BlackRock’s overall operations and its efforts to expand the scale of, and improve the quality of, its operations. The Board also noted that, subject to applicable law, BlackRock may use and benefit from third-party research obtained by soft dollars generated by certain registered fund transactions to assist in managing all or a number of its other client accounts.
In connection with its consideration of the Agreements, the Board also received information regarding BlackRock’s brokerage and soft dollar practices. The Board received reports from BlackRock which included information on brokerage commissions and trade execution practices throughout the year.
The Board noted the competitive nature of the ETF marketplace, and that shareholders are able to redeem or sell their Fund shares if they believe that each Fund’s fees and expenses are too high or if they are dissatisfied with the performance of each Fund.
Conclusion
At the June Meeting, in a continuation of the discussions that occurred during the May Meeting, and as a culmination of the Board’s year-long deliberative process, the Board, including the Independent Board Members, unanimously approved the continuation of the Advisory Agreement between the Manager and the Trust, on behalf of each Fund, for a one-year term ending June 30, 2026, and the Sub-Advisory Agreements between the Manager and the Sub-Advisor, with respect to BINC and BRTR, for a one-year term ending June 30, 2026. Based upon its evaluation of all of the aforementioned factors in their totality, as well as other information, the Board, including the Independent Board Members, was satisfied that the terms of the Agreements were fair and reasonable and in the best interest of each Fund and its shareholders. In arriving at its decision to approve the Agreements, the Board did not identify any single factor or group of factors as all-important or controlling, but considered all factors together, and different Board Members may have attributed different weights to the various factors considered. The Independent Board Members were advised by independent legal counsel throughout the deliberative process.
