Fund profile
As filed in the prospectus · 2025 Q3
The iShares Core S&P Mid-Cap ETF (the Fund ) seeks to track the investment results of an index composed of mid-capitalization U.S. equities.
The fund tracks the S&P MidCap 400 Index using representative sampling, holding a sample of mid-capitalization U.S. equities with similar investment and fundamental characteristics to the index rather than all constituents. Because the fund may not hold all index securities, its returns may diverge from the index it seeks to track.

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.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Feb 2026
Mar 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
