ISHARES 7-10 YEAR TREASURY B

Investment objective: The iShares 7-10 Year Treasury Bond ETF (the Fund ) seeks to track the investment results of an index composed of U.S. Treasury bonds with remaining maturities between seven and ten years.

Principal investment strategies: The Fund seeks to track the investment results of the ICE U.S. Treasury 7-10 Year Bond Index (the Underlying Index ), which measures the performance of public obligations of the U.S. Treasury that have a remaining maturity of greater than seven years and less than or equal to ten years. As of February 28, 2026, there were 13 issues in the Underlying Index. The Underlying Index consists of publicly-issued U.S. Treasury securities that have a remaining maturity of greater than or equal to seven years and less than ten years and have $300 million or more of outstanding face value, excluding amounts held by the Federal Reserve System (the Fed ). In addition, the securities in the Underlying Index must be fixed-rate and denominated in U.S. dollars. Excluded from the Underlying Index are inflation-linked securities, Treasury bills, cash management bills, any government agency debt issued with or without a government guarantee, original issue zero-coupon securities and zero-coupon issues that have been stripped from coupon-paying bonds. However, the amounts outstanding of qualifying securities are not reduced by any individual components of such securities (i.e., coupon or principal) that have been stripped after inclusion in the Underlying Index. Securities issued or marketed primarily to retail investors do not qualify for inclusion in the Underlying Index. The Underlying Index is market value weighted, and the securities in the Underlying Index are updated on the last calendar day of each month. BFA uses an indexing approach to try to achieve the Funds investment objective. The Fund does not try to beat the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued. Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by aiming to keep portfolio turnover low in comparison to actively managed investment companies. BFA uses a representative sampling indexing strategy to manage the Fund. Representative sampling is an indexing strategy that involves investing in a representative sample of securities or other instruments that collectively has an investment profile similar to that of an applicable underlying index. The instruments selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and industry weightings), fundamental characteristics (such as return variability, duration ( i.e. , an instrument's price sensitivity to a change in interest rates), maturity or credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the components of the Underlying Index. The Fund will invest at least 80% of its assets in the component securities of the Underlying Index, and the Fund will invest at least 90% of its assets in U.S. Treasury securities that BFA believes will help the Fund track the Underlying Index. The Fund will invest no more than 10% of its assets in futures, options and swaps contracts that BFA believes will help the Fund track the Underlying Index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund. The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received). The Underlying Index is sponsored by ICE Data Indices, LLC (the Index Provider or IDI ), which is ? independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the components of the Underlying Index and publishes information regarding the market value of the Underlying Index.
