Fund profile

As filed in the prospectus · 2025 Q3

The iShares Russell 1000 ETF (the Fund ) seeks to track the investment results of an index composed of large- and mid-capitalization U.S. equities.

Strategy · summarised

The fund tracks the Russell 1000 Index, a float-adjusted market-capitalization-weighted index of approximately 1,007 large- and mid-capitalization U.S. equities, using representative sampling to hold a portfolio with similar investment and fundamental characteristics to the index. Because the fund may not hold all index securities, its returns may diverge from the index. A significant portion of the index is concentrated in technology sector securities.

The outer band is exposure held short — written against the portfolio rather than part of it, which is why it sits outside the ring and why the two are never netted into one figure.

Derivatives are shown at market value, not notional exposure.
