#### Supplement dated October 31, 2025

#### to the currently effective Summary Prospectus, Prospectus,

#### and Statement of Additional Information ("SAI") for the

#### iShares 0-3 Month Treasury Bond ETF (SGOV) and

#### iShares Short Treasury Bond ETF (SHV)

#### (each, a "Fund" and collectively, the "Funds")
Effective on or around December 10, 2025, the following name change will be effective:

| &nbsp;&nbsp;&nbsp; iShares Short Treasury Bond ETF | iShares 0–1 Year Treasury Bond ETF |

In addition, effective after the October 31, 2025 rebalancing, the Underlying Index of each Fund, as such term is defined in each Fund's Summary Prospectus and Prospectus, will reinvest cash flows from coupon payments and the proceeds of maturing component securities prior to the next rebalancing. Prior to October 31, 2025, the Underlying Index of each Fund did not reinvest the cash flows. Accordingly, the following strategy changes are effective immediately:

• The third paragraph of the section entitled Principal Investment Strategies of the Summary Prospectus and Prospectus for SGOV is deleted in its entirety.

• The following is added as the new third paragraph of the section entitled Principal Investment Strategies of the Summary Prospectus and Prospectus for each Fund:

• The Underlying Index's cash from coupon payments and the proceeds of maturing component securities will receive a return equal to that of the ICE US 1-Month Treasury Bill Index from the point of which cash is received until the end of the month. The Underlying Index's cash position is treated as cash and cash equivalents by the Fund, so the Fund may have material positions in cash and cash equivalents, including money market funds. Prior to October 31, 2025, the cash from coupon payments and the proceeds of maturing component securities did not earn any reinvestment income.

• The second and third to last sentences in ICE 0-3 Month US Treasury Securities Index and ICE Short US Treasury Securities Index sections of the Funds' SAI on pages 116 and 117 are each deleted in their entirety and replaced with the following:

• The Underlying Index's cash from coupon payments and the proceeds of maturing component securities will receive a return equal to that of the ICE US 1-Month Treasury Bill Index from the point of which cash is received until the end of the month when cash, including the return on cash, is removed as part of the rebalancing. Prior to October 31, 2025, cash flows from coupon payments and the proceeds of maturing component securities did not earn any reinvestment income.
