C000234050 Investment Objective and Strategy

iShares U.S. Intermediate Government Bond Index Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Blackrock Funds.

Investment objective

The investment objective of iShares U.S. Intermediate Government Bond Index Fund (the Fund), a series of BlackRock Funds SM (the Trust), is to seek to provide investment results that correspond to the total return performance of fixed-income securities, in aggregate, as represented by the Bloomberg U.S. Government: Intermediate Index (or the Underlying Index).

Principal investment strategy

Under normal circumstances, at least 90% of the value of the Funds assets, plus the amount of any borrowings for investment purposes, is invested in securities comprising the Bloomberg U.S. Government: Intermediate Index, which, for the Fund, are considered bonds issued or guaranteed by the U.S. Government and its agencies or instrumentalities. The Fund attempts to achieve, in both rising and falling markets, a correlation of at least 95% between the total return of its net assets before fees and expenses and the total return of the Funds benchmark index, the Bloomberg U.S. Government: Intermediate Index. Notwithstanding the factors described below, perfect (100%) correlation would be achieved if the total return of the Funds net assets, before fees and expenses, increased or decreased exactly as the total return of the Funds benchmark index increased or decreased.

The Funds ability to match its investment performance to the investment performance of its benchmark index may be affected by, among other things, the Funds expenses, the amount of cash and cash equivalents held by the Fund, the manner in which the total return of the Funds benchmark index is calculated, the size of the Funds investment portfolio, and the timing, frequency and size of shareholder purchases and redemptions. The Bloomberg U.S. Government: Intermediate Index is a capitalization weighted index that measures U.S. dollar-denominated, fixed-rate, nominal U.S. Treasuries and U.S. agency debentures (securities issued by U.S. government owned or government sponsored entities, and debt explicitly guaranteed by the U.S. government) with a maturity equal or greater than one year and less than ten years.

The index is rebalanced monthly. There were approximately 463 fixed-income securities included in the Bloomberg U.S. Government: Intermediate Index as of December 31, 2025. All securities in the Bloomberg U.S. Government: Intermediate Index are rated investment-grade. The Fund will be invested and reinvested primarily in U.S. debt securities with maturities greater than one year but less than ten years, with the objective of approximating as closely as practicable the total rate of return of the Bloomberg U.S. Government: Intermediate Index. Under normal circumstances, the Fund expects to have a dollar-weighted average maturity of three to ten years, although the Funds dollar-weighted average maturity may go below three years to the extent it does so for the benchmark index. The Fund utilizes sampling techniques that are designed to allow the Fund to duplicate substantially the investment performance of the Bloomberg U.S.

Government: Intermediate Index. However, the Fund is not expected to track the Bloomberg U.S. Government: Intermediate Index with the same degree of accuracy that complete replication of the Bloomberg U.S. Government: Intermediate Index would provide. No attempt is made to manage the Fund using economic, financial or market analysis. In addition, at times, the portfolio composition of the Fund may be altered (or rebalanced) to reflect changes in the characteristics of the index that the Fund tracks. The Fund also may engage in futures, forwards and options transactions and other derivative securities transactions and lend its portfolio securities, each of which involves risk. The Fund may use futures contracts, forwards, options and other derivative transactions to manage its short-term liquidity and/or as substitutes for comparable market positions in the securities in its benchmark index.

The Fund may also invest in high-quality money market instruments, including shares of money market funds advised by BFA or its affiliates.
