    Costs paid as a percentage of a
    $10,000 investment
    iShares 0-5 Year High Yield Corporate Bond ETF $33 0.31%
    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 13.78%.
    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Markit iBoxx® USD Liquid High Yield 0-5 Index returned 13.93%.
    What contributed to performance?
    Short-term high yield bonds were supported during the reporting period by an environment of slowing pricing pressures and steady growth, including the first rate cut by the U.S. Federal Reserve since March 2020. These issues also benefited from declining credit spreads (the difference in the yield between two bonds with similar maturities but different credit qualities) during the reporting period as fundamentals remained resilient. Consumer service bonds within the consumer cyclicals sector were the strongest contributors to the Fund’s return. Within the communications sector, cable and satellite issues also supported performance. Within credit quality, all high yield rating buckets contributed positively to performance.
    What detracted from performance?
    There were no significant detractors to the Fund’s performance during the reporting period.

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 8.03%.
    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Markit iBoxx® USD Liquid Investment Grade 0-5 Index returned 8.04%.
    What contributed to performance?
    Bond returns were supported by an environment of slowing pricing pressures and steady growth in the United States. Expectations for interest rate cuts grew, and those hopes were realized in September 2024 when the U.S. Federal Reserve lowered short-term interest rates by a 50 basis point cut, its first rate reduction since March 2020. Investment-grade corporate bonds with short (zero to three years) to intermediate maturities (three to seven years)benefited from the decrease in yields over the period. The Fund’s allocation to 0-5 year bonds contributed to its positive performance. In terms of credit quality, bonds rated A and Baa by Moody’s, contributed the most to performance. Within sectors, banking aided returns, supported by the prospects of monetary easing.
    What detracted from performance?
    There were no meaningful detractors from the Fund’s performance during the reporting period.

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 6.52%.
    • For the same period, the FTSE World Broad Investment-Grade Bond Index returned 9.98% and  the FTSE World Government Bond Index – Developed Markets 1-3 Years Capped Select Index returned 6.76%.
    What contributed to performance?
    During the reporting period, short-term Treasury returns were supported by an environment of moderating inflationary pressures and stable economic growth. Amid worries about growth prospects, the European Central Bank cut rates three times, while the United States economy stayed strong, prompting the U.S. Federal Reserve Bank to wait until September before decreasing short-term interest rates for the first since 2020. Eurozone bonds were the Fund’s top performers, led by Italian bonds, which benefited from the economic and fiscal approach of Italy’s new government. French Treasury bonds also contributed. Bonds with maturities over 10 years, which are the most sensitive to interest rate changes, were also meaningful contributors.
    What detracted from performance?
    There were no significant detractors during the reporting period.

    What contributed to performance?

Leading up to the rate cut, Treasury yields moved lower, the 10-year note moving from 4.93% to end the reporting period at 4.28%. (Bond prices and yields move in opposite directions).
    What detracted from performance?
    During the reporting period, writing (selling) one-month covered call options to generate income detracted from the Fund’s performance.

Expectations for interest rate cuts grew, and those hopes were realized in September 2024 when the U.S. Federal Reserve Bank (“Fed”) lowered short-term interest rates by a 50 basis point cut, its first rate reduction since March 2020. Among sectors, industrial bonds, specifically consumer non-cyclical and technology, contributed positively to performance. Financial sector bonds also contributed positively to performance, driven by the banking sector. By credit quality, the Fund’s allocation to A-rated bonds benefited the Fund’s return.
    What detracted from performance?
    During the reporting period, there were no significant detractors from the Fund’s return.

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 14.44%.
    • For the same period, the ICE BofA US Broad Market Index returned 10.55% and the ICE BofA BB US High Yield Constrained Index returned 14.51%.
    What contributed to performance?
    U.S. intermediate-term bonds (between three and ten years) were the largest contributors to the Fund’s return during the reporting period. Bond prices rose as yields fell (bond yields and prices move in opposite directions) amid an environment of slowing pricing pressures and steady growth in the United States. Expectations for interest rate cuts grew, and those expectations were realized in September 2024 when the U.S. Federal Reserve Bank lowered short term interest rates by 50 basis points, its first-rate reduction since March 2020. Among sectors, notable contributors included consumer cyclical and financial bonds. Additionally, the Fund’s allocation to lower-risk high-yield bonds rated Ba by Moody’s, benefited performance.
    What detracted from performance?
    During the reporting period, there were no significant detractors from the Fund’s return.

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 16.68%.
    • For the same period, the ICE BofA US Broad Market Index returned 10.55% and the ICE BofA US High Yield Constrained Index returned 16.49%.
    What contributed to performance?
    Bond returns in the United States were supported during the reporting period by an environment of slowing pricing pressures and steady growth in the United States. Expectations for interest rate cuts grew, and those hopes were realized in September when the U.S. Federal Reserve lowered interest rates by a 50 basis point cut, its first rate reduction since March 2020. High-yield issues were helped by declining credit spreads (the difference in the yield between two bonds with similar maturities but different credit qualities) as fundamentals remained resilient. By sector, consumer cyclicals contributed the most to performance, as retailers were supported by a resilient consumer, while the consumer non cyclicals space was helped by healthcare issues. Within credit quality, performance was helped by bonds across the high-yield rating spectrum, with those rated BB delivering the strongest performance.
    What detracted from performance?
    There were no significant detractors to the Fund’s performance during the reporting period.

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 10.38%.
    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Bloomberg U.S. CMBS (ERISA Only) Index returned 10.75%.
    What contributed to performance?
    The largest driver of bond prices during the reporting period was the anticipation of easing monetary policy by the U.S. Federal Reserve, which increased optimism in commercial mortgage-backed securities (“CMBS”). The central bank did cut rates in September by 50 basis points amid an environment of slowing pricing pressures and steady growth. Spreads for CMBS over Treasuries have tightened, given the strong demand that absorbed new issue supply, especially for newly issued deals. (A spread is the difference in yield between a U.S. Treasury bond and a specific commercial mortgage-backed security.)
    What detracted from performance?
    While there were no significant detractors from the Fund’s return during the reporting period, secular challenges in the office sector remain as stalled rent growth, increased financing costs, higher operating expenses, and cap rate resets have raised refinancing hurdles in the commercial real estate market.

    • For the reporting period ended October 31, 2024, the Fund returned 20.91%.
    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Bloomberg U.S. Convertible Cash Pay Bond>$250MM Index returned 21.18%.
    What contributed to performance?
    Bond returns were supported by an environment of slowing pricing pressures and steady growth in the United States during the reporting period. Growing expectations for interest rate cuts, and the eventual rate cut in September pushed yields down and prices higher. (Bond yields and prices move in opposite directions.) The Fund’s substantial exposure to the consumer cyclicals (supported by robust consumer spending) and information technology sectors meaningfully contributed to performance. Given the hybrid structure of convertible bonds, rising equity prices, particularly among information technology companies, supported the Fund’s return. Convertible bonds are issued by companies with high expectations for future earnings, making them a popular form of financing for many companies. Among credit quality, much of the convertible universe is unrated, and these issues contributed positively to returns.
    What detracted from performance?
    Bonds rated B, slightly detracted from the Fund’s return during the reporting period.

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 7.81%.
    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Bloomberg U.S. Universal 1-5 Year Index returned 7.85%.
    What contributed to performance?
    Bond returns in the United States were supported during the reporting period by an environment of slowing pricing pressures and steady growth, including the first rate cut by the U.S. Federal Reserve Bank (“Fed”) since March 2020. Corporate bonds contributed the most to the Fund’s performance, led by the industrial and financial sector. Treasuries also registered solid gains, as clarity on the Fed’s policy direction drove Treasury yields lower, the 10-year Treasury decreased from 4.93% to 4.29% during the reporting period. (Bond yields and prices move in opposite directions.) Within credit quality, AA rated bonds contributed to performance.
    What detracted from performance?

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 9.61%.
    • For the same period, the Bloomberg Global Aggregate Bond Index returned 9.54% and the Bloomberg Global Aggregate ex USD 10% Issuer Capped (Hedged) Index returned 9.56%.
    What contributed to performance?
    Euro bloc bonds were the largest contributors to the Fund’s return during the reporting period as slowing pricing pressures supported longer-term maturity treasury and government-related issues. Bond prices gained, and yields fell as both the European Central Bank (“ECB”) and the U.S. Federal Reserve began to ease monetary policy, with the ECB cutting rates three times. (Bond prices and yields move in opposite directions.) In particular, French debt benefited from the economic and fiscal strategy navigated by the country’s new government. Italian and German bonds were also meaningful contributors. In the Asia bloc, Chinese bonds were supported by government stimulus measures. Longer-term issues, which are more sensitive to interest rate movements, contributed to returns. By credit quality, investment-grade issues rated Aa supported performance.
    What detracted from performance?
    There were no significant detractors to the Fund’s returns during the reporting period.

Demand for green bonds, used to finance or refinance environmental or social projects or activities, has steadily increased. Wirelines bonds, as well as cable and satellite, in the communications sector, contributed the most to performance. Among consumer cyclicals bonds, retailers supported performance helped by a resilient consumer. Within credit quality, performance was strong across high-yield ratings.

    There were no significant detractors to the Fund’s performance during the reporting period.

    • For the reporting period ended October 31, 2024, the Fund returned 17.00%.
    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Bloomberg US High Yield Fallen Angel 3% Capped Index returned 16.13%.
    What contributed to performance?
    Bond returns were supported by an environment of slowing pricing pressures and steady growth in the United States during the reporting period. Expectations for interest rate cuts grew, and those hopes were realized in September 2024 when the U.S. Federal Reserve lowered short-term interest rates by a 50 basis point cut, its first rate reduction since March 2020. By sector, the consumer cyclicals sector led, supported by retailers and communication sectors. Within credit quality, the lowest risk rating of high-yield bonds, rated Ba by Moody’s contributed the most to performance, followed by bonds rated B.
    What detracted from performance?
    There were no significant detractors to the Fund’s performance during the reporting period.

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 6.61%.
    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Bloomberg US Floating Rate Note<5 Years Index returned 6.62%.
    What contributed to performance?
    Bond prices gained and yields fell during the reporting period as the U.S. Federal Reserve lowered short-term interest rates by 50 basis point cut, its first-rate reduction since March 2020. The prospect of lower rates put downward pressure on floating-rate bonds as interest rates fell. The European Central Bank began its monetary easing cycle prior to the United States. As such, U.S. rates were higher for longer and U.S. bonds were meaningful contributors to the Fund’s return. Among sectors, financials were the largest contributors, particularly the banking sector, which was supported by the prospect of monetary easing. By credit quality, A-rated bonds were the largest contributors to performance.
    What detracted from performance?
    There were no significant detractors from the Fund’s return during the reporting period.

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 10.75%.
    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Bloomberg U.S. GNMA Bond Index returned 10.69%.
    What contributed to performance?
    The largest driver of performance during the reporting period was the easing of monetary policy by the U.S. Federal Reserve Bank. The central bank cut rates in September by 50 basis points amid an environment of slowing pricing pressures and steady growth. This was beneficial to mortgage-backed securities, including Government National Mortgage Association (“GNMA”) bonds, as yields fell (bond prices and yields move in opposite directions). The pivot to lower interest rates benefited longer-term issues, which are more sensitive to interest rate movements, and the Fund’s allocation to issues between five and seven years meaningfully contributed to performance.
    What detracted from performance?
    There were no significant detractors from the Fund’s return during the reporting period.

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 9.21%.
    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Cboe HYG BuyWrite Index returned 9.23%.
    What contributed to performance?
    Bond returns were supported by an environment of slowing pricing pressures and steady growth in the United States during the reporting period. Expectations for interest rate cuts grew, and those expectations were realized in September 2024 when the U.S. Federal Open Market Committee lowered short-term interest rates by 50 basis point, its first-rate reduction since March 2020. The healthy economic backdrop further supported high-yield issues, which contributed to the Fund’s returns. During the reporting period, issues in the consumer cyclicals sector benefited performance, most notably among retailers and consumer service companies, supported by robust consumer strength and spending. Cable and satellite issues in the communications sector also registered strong returns. By credit rating, securities considered lower risk high yield, rated Ba and B by Moody’s were additive to performance amid a less risk-averse environment.
    What detracted from performance?
    During the reporting period, writing (selling) one-month covered call options to generate income detracted from the Fund’s performance.

Expectations for interest rate cuts grew, and those hopes were realized in September 2024 when the U.S. Federal Reserve lowered interest rates by a 50 basis point cut, its first rate reduction since March 2020.

Allocations to financial bonds also contributed to performance.
    Additionally, Term Maturity Funds with earlier maturity dates benefited from bonds with credit ratings near the lower range of investment grade and the higher end of high yield (those rated Baa and Ba by Moody’s.) Term Maturity Funds with later maturity dates were supported by bonds with credit ratings that were on the lower risk spectrum of high yield (those rated Ba and B by Moody’s), as credit spreads (the difference in the yield between two bonds with similar maturities but different credit qualities) narrowed during the reporting period.

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 12.58%.
    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Bloomberg 2026 Term High Yield and Income Index returned 13.04%.
    What contributed to performance?
    U.S. corporate bonds registered solid gains during the reporting period, supported by an environment of slowing pricing pressures and steady growth in the United States. Expectations for interest rate cuts grew, and those hopes were realized in September 2024 when the U.S. Federal Reserve lowered interest rates by a 50 basis point cut, its first rate reduction since March 2020. Both Term Maturity Funds with earlier maturity dates and Term Maturity Funds with later maturity dates, consumer cyclicals and consumer non-cyclical bonds in the industrial sector contributed the most to returns. Allocations to financial bonds also contributed to performance.
    Additionally, Term Maturity Funds with earlier maturity dates benefited from bonds with credit ratings near the lower range of investment grade and the higher end of high yield (those rated Baa and Ba by Moody’s.) Term Maturity Funds with later maturity dates were supported by bonds with credit ratings that were on the lower risk spectrum of high yield (those rated Ba and B by Moody’s), as credit spreads (the difference in the yield between two bonds with similar maturities but different credit qualities) narrowed during the reporting period.
    What detracted from performance?
    During the reporting period, there were no significant detractors from the Fund’s  performance.

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 5.90%.
    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Bloomberg December 2024 Maturity Corporate Index returned 5.24%.
    What contributed to performance?
    U.S. corporate bond returns were supported by an environment of slowing pricing pressures and steady growth during the reporting period. The yield on the 10-year Treasury was volatile as investors tried to determine the next moves of the U.S. Federal Reserve. Expectations for interest rate cuts grew, and those hopes were realized in September 2024 when the U.S. Federal Reserve lowered short-term interest rates by 50 basis points, its first-rate reduction since March 2020.
    Leading up to the interest rate decision meeting, Treasury yields moved lower before trending steadily higher following September’s rate cut. In anticipation of rate cuts, the yield curve (the difference between a shorter-term bond and a longer-term bond, most often gauged by the two-year Treasury note and the 10-year Treasury note) narrowed. Intermediate maturity issues, those between three and five years for earlier term funds and those between seven and 10 years for later dated Term Funds, contributed to the Fund’s performance during the reporting period. For both earlier and later dated Term Funds, exposure to bonds that are on the lower range of investment grade benefited performance. At the sector level, financial issues performed well across Term Funds, particularly among banking bonds that were supported by hopes of a lower interest rate environment.
    What detracted from performance?
    There were no notable detractors from the Fund’s performance during the reporting period.
    The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

    iShares iBonds Dec 2025 Term Corporate ETF $10 0.10%
    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 6.73%.
    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Bloomberg December 2025 Maturity Corporate Index returned 6.80%.
    What contributed to performance?
    U.S. corporate bond returns were supported by an environment of slowing pricing pressures and steady growth during the reporting period. The yield on the 10-year Treasury was volatile as investors tried to determine the next moves of the U.S. Federal Reserve. Expectations for interest rate cuts grew, and those hopes were realized in September 2024 when the U.S. Federal Reserve lowered short-term interest rates by 50 basis points, its first-rate reduction since March 2020.
    Leading up to the interest rate decision meeting, Treasury yields moved lower before trending steadily higher following September’s rate cut. In anticipation of rate cuts, the yield curve (the difference between a shorter-term bond and a longer-term bond, most often gauged by the two-year Treasury note and the 10-year Treasury note) narrowed. Intermediate maturity issues, those between three and five years for earlier term funds and those between seven and 10 years for later dated Term Funds, contributed to the Fund’s performance during the reporting period. For both earlier and later dated Term Funds, exposure to bonds that are on the lower range of investment grade benefited performance. At the sector level, financial issues performed well across Term Funds, particularly among banking bonds that were supported by hopes of a lower interest rate environment.
    What detracted from performance?
    There were no notable detractors from the Fund’s performance during the reporting period.

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 11.67%.
    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Bloomberg December 2029 Maturity Corporate Index returned 11.70%.
    What contributed to performance?
    U.S. corporate bond returns were supported by an environment of slowing pricing pressures and steady growth during the reporting period. The yield on the 10-year Treasury was volatile as investors tried to determine the next moves of the U.S. Federal Reserve. Expectations for interest rate cuts grew, and those hopes were realized in September 2024 when the U.S. Federal Reserve lowered short-term interest rates by 50 basis points, its first-rate reduction since March 2020.
    Leading up to the interest rate decision meeting, Treasury yields moved lower before trending steadily higher following September’s rate cut. In anticipation of rate cuts, the yield curve (the difference between a shorter-term bond and a longer-term bond, most often gauged by the two-year Treasury note and the 10-year Treasury note) narrowed. Intermediate maturity issues, those between three and five years for earlier term funds and those between seven and 10 years for later dated Term Funds, contributed to the Fund’s performance during the reporting period. For both earlier and later dated Term Funds, exposure to bonds that are on the lower range of investment grade benefited performance. At the sector level, financial issues performed well across Term Funds, particularly among banking bonds that were supported by hopes of a lower interest rate environment.
    What detracted from performance?
    There were no notable detractors from the Fund’s performance during the reporting period.

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 9.14%.
    • For the same period, the FTSE World Broad Investment-Grade Bond Index returned 9.98% and the FTSE World Government Bond Index - Developed Markets Capped Select Index returned 9.39%.
    What contributed to performance?
    Treasury returns were supported during the reporting period by an environment of slowing pricing pressures. Amid worries about growth prospects, the European Central Bank cut rates three times, while the United States economy stayed strong, prompting the U.S. Federal Reserve Bank to wait until September before decreasing short-term interest rates for the first time since 2020. Euro bloc bonds were the Fund’s strongest performers, led by Italy. Italian government debt benefited from the economic and fiscal strategy implemented by the country’s new government. France’s Treasury bonds were also meaningful contributors. By maturity, bonds over 10 years, which are the most sensitive to interest rate changes, registered the largest returns.
    What detracted from performance?
    During the reporting period, Japanese Treasuries slightly detracted from the Fund’s performance. The country’s government bonds declined as the Bank of Japan raised interest rates in March 2024, for the first time since 2007, ending a period of negative rates. The central bank then raised rates in July 2024 again, which pushed yields higher (bond prices and yields move in opposite directions).

    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Cboe LQD BuyWrite Index returned 6.05%.
    What contributed to performance?
    Bond returns were supported by an environment of slowing pricing pressures and steady growth in the United States during the reporting period. Expectations for interest rate cuts grew, and those hopes were realized in September 2024 when the U.S. Federal Reserve lowered short-term interest rates by a 50 basis point cut, its first rate reduction since March 2020. During the reporting period, the strategy posted positive returns by seeking to track the investment results of an investment grade corporate index that reflects the iShares iBoxx $ Investment Grade Corporate Bond ETF while writing (selling) one-month covered call options to generate income. Over the reporting period, the financial sector contributed to the Fund’s return, led by the banking sector which benefited from the prospect of lower interest rates. By credit rating, investment-grade securities, particularly those rated A by Moody’s, were additive to performance. However, Baa-rated issues also contributed due to investors' increased risk appetite during the reporting period.
    What detracted from performance?
    During the reporting period, writing (selling) one-month covered call options to generate income detracted from the Fund’s performance.

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 17.10%.
    • For the same period, the J.P. Morgan EMBI Global Diversified Index returned 18.16% and the J.P. Morgan EM Sovereign and Corporate Credit Core Index returned 17.36%.
    What contributed to performance?
    Emerging market bonds delivered strong returns during the reporting period, particularly among sovereign bond issuers, which were leading contributors to the Fund’s return. U.S. dollar-denominated emerging market debt is sensitive to rate changes in the United States, as many of these countries borrow in U.S. dollars and must repay the principal and interest in U.S. dollars. Expectations of interest rate cuts and then a cut by the U.S. Federal Reserve in September helped these bonds move higher. Across emerging markets, all regions gained, led by Latin America. In particular, efforts by Argentina’s new administration to lower inflation improved investor sentiment and bolstered local bond markets. Longer-term duration bonds, those over 10 years, outpaced their shorter-term counterparts during the reporting period, followed by intermediate maturity bonds. While bonds of all credit ratings delivered positive performance, investment-grade bonds rated BBB had the greatest positive impact.
    What detracted from performance?
    There were no detractors from the Fund’s return during the reporting period.

    • For the same period, the J.P. Morgan EMBI Global Diversified Index returned 18.16% and the J.P. Morgan EMBI® Global Core Index returned 18.68%.
    What contributed to performance?
    Emerging market sovereign bonds were leading contributors to the Fund’s return during the reporting period. Expectations of interest rate cuts and then a cut by the U.S. Federal Reserve in September helped these bonds move higher. Across emerging markets, all regions gained, led by Latin America. In particular, efforts by Argentina’s new administration to lower inflation improved investor sentiment and bolstered local bond markets. In the Middle East, Egyptian bonds were bolstered on expectations that the country would receive billions in foreign loans and investments, potentially offsetting dismal economic growth and the threat of spillover from the war in Gaza. Longer-term duration bonds, those over 10 years, outpaced their shorter-term counterparts during the reporting period. While bonds of all credit ratings delivered positive performance, investment-grade bonds had the greatest positive impact.
    What detracted from performance?
    Venezuelan bonds detracted slightly from the Fund’s performance during the reporting period, as the country’s highly contested presidential election and economic crisis put downward pressure on bonds.

    How did the Fund perform during the period?
    • For the reporting period ended October 31, 2024, the Fund returned 2.26%.
    • For the same period, the iShares Russell 2000 ETF returned 8.92% and the Cboe FTSE Russell IWM 2% OTM BuyWrite Index returned 1.94%.
    What contributed to performance?
    During the reporting period, equity markets registered remarkably strong gains and contributed to the Fund’s return amid increasing investor confidence, limited volatility, and slowing inflation. Declining yields and solid economic growth resulted in a broad equity rally that extended to include small-cap stocks, which have historically done well in periods of moderating inflation. Investor appetite for equities continued to increase when the U.S. Federal Reserve Bank lowered short-term interest rates by 50 basis points in September, a larger-than-expected rate cut and the first since March 2020.
    By selling monthly options, the Fund generates option premium, which it distributes to investors monthly. The level of this premium is influenced by market-implied volatility.
    What detracted from performance?
    Against this backdrop, the Russell 2000 Index rallied in the second half of the year, and the iShares Russell 2000 BuyWrite ETF participated in a portion of these gains. However, as the Fund sells monthly call options approximately 2% out of the money, its price returns were capped, limiting participation in upside beyond the 2% call strike.

Leading up to the interest rate decision meeting, Treasury yields moved lower but have trended steadily higher following September’s rate cut, and the 10-year Treasury ultimately ending the period at 4.28%, down from 4.93%, while the yield on the three-month Treasury note sank to 4.54% from 5.46% a year earlier. (Bond prices and yields move in opposite directions.) Treasury floating rate notes are issued with maturities of two years and coupons that reset periodically based on the three-month Treasury bill rate.

    Annual Shareholder Report — October 31, 2024

    This annual shareholder report contains important information about iShares U.S. Fixed Income Balanced Risk Systematic ETF (the “Fund”) (formerly known as iShares U.S. Fixed Income Balanced Risk Factor ETF) for the period of November 1, 2023 to October 31, 2024. You can find additional information about the Fund at blackrock.com/fundreports. You can also request this information by contacting us at 1‑800‑iShares (1‑800‑474‑2737).

    How did the Fund perform last year?
    • For the reporting period ended October 31, 2024, the Fund returned 12.04%.
    • For the same period, the Bloomberg U.S. Universal Index returned 11.20% and the Bloomberg U.S. Fixed Income Balanced Risk Index returned 12.16%.
    What contributed to performance?
    Bond returns were supported by an environment of slowing pricing pressures and steady growth in the United States. Expectations for interest rate cuts grew, and those hopes were realized in September 2024 when the U.S. Federal Reverse lowered short-term interest rates by a 50 basis point cut, its first rate reduction since March 2020. By sector, industrial bonds, supported by consumer cyclical and communication, and banking bonds contributed to performance. Investment-grade bonds rated A and Baa by Moody’s were meaningful contributors.
    What detracted from performance?
    There were no significant detractors to the Fund’s performance during the reporting period.

Utility corporate bonds had a positive impact on performance, as did real estate investment trusts (“REITs”) and banking in the financial sector.

    (a)
    The Fund's classification changed from non-diversified to diversified during the reporting period.
    (b)
    The Fund commenced operations on May 22, 2024.
    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:
    Investment Transactions 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, and payment-in-kind interest are recognized daily on an accrual basis.
    Foreign Currency Translation: 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 prevailing market rates as quoted by one or more data service providers. 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.  
    Bank Overdraft: Certain Funds had outstanding cash disbursements exceeding deposited cash amounts at the custodian during the reporting period. The Funds are 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.
    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.

    3. INVESTMENT VALUATION 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 Trustees of the Trust (the “Board”) of each Fund has approved the designation of BlackRock Fund Advisors (“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. BFA has 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 or current market quotations provided by independent dealers or third-party pricing services. 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 may trade at lower prices than institutional round lots. 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.
    • Investments in open-end U.S. mutual funds (including money market funds) are valued at that day’s NAV.
    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.
    Fair value pricing could result in a difference between the prices used to calculate a fund’s NAV and the prices used by the fund’s underlying index, which in turn could result in a difference between the fund’s performance and the performance of the fund’s underlying index.
    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 the 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 privately held companies or funds 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
    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.

    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 Lending Agreements (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:

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.
    5. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
    Investment Advisory Fees: Pursuant to an Investment Advisory Agreement with the Trust, BFA manages the investment of each Fund’s assets. BFA is a California corporation indirectly owned by BlackRock. Under the Investment Advisory Agreement, BFA is responsible for substantially all expenses of the Funds, except (i) interest and taxes; (ii) brokerage commissions and other expenses connected with the execution of portfolio transactions; (iii) distribution fees; (iv) the advisory fee payable to BFA; and (v) litigation expenses and any extraordinary expenses (in each case as determined by a majority of the independent trustees).
    For its investment advisory services to each Fund, BFA is entitled to an annual investment advisory fee of 0.35%, accrued daily and paid monthly by the Funds, based on the average daily net assets of each Fund.

    Notes to Financial Statements  (continued)
    Expense Waivers: A fund may incur its pro rata share of fees and expenses attributable to its investments in other investment companies ("acquired fund fees and expenses"). The total of the investment advisory fee and acquired fund fees and expenses, if any, is a fund’s total annual operating expenses. Total expenses as shown in the Statements of Operations does not include acquired fund fees and expenses.
    BFA has contractually agreed to waive a portion of its investment advisory fee for each Fund through the termination date of such Fund, in an amount equal to acquired fund fees and expenses, if any, attributable to each Fund's investments in other funds advised by BFA or its affiliates.
    These amounts are included in investment advisory fees waived in the Statements of Operations. For the year ended October 31, 2024, the amounts waived in investment advisory fees pursuant to these arrangements were as follows:

    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.
    ETF Servicing 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.
    Prior to January 26, 2024 (date of conversion for respective funds), ETF Services were performed by State Street Bank and Trust Company.
    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 each Fund bears to an annual rate of 0.04%. The SL Agency 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 all 1940 Act iShares exchange-traded funds (the “iShares ETF 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 October 31, 2024, the Funds paid BTC the following amounts for securities lending agent services:

    Officers and Trustees: Certain officers and/or trustees of the Trust are officers and/or trustees of BlackRock or its affiliates.

    7. INCOME TAX INFORMATION
    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 October 31, 2024, 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 October 31, 2024, permanent differences attributable to certain deemed distributions and realized gains (losses) from in-kind redemptions were reclassified to the following accounts:
