**TOUCHSTONE FUNDS GROUP TRUST**

**Touchstone Ultra Short Duration Fixed** <br> **Income Fund (the "Fund")**

**Supplement dated April 10, 2026, to the Fund's Summary Prospectus dated January 28, 2026, as may be amended or supplemented from time to time**

**<u>Changes in Additional Indexes</u>**

The Board of Trustees of the Touchstone Funds Group Trust (the "Trust") has approved changes to the additional indexes of the Fund.

As of April 10, 2026 ("the Effective Date"), the first paragraph under the heading "The Fund's Performance" in the Summary Prospectus is deleted in its entirety and replaced with:

The bar chart and performance table below illustrate some indication of the risks and volatility of an investment in the Fund by showing changes in the Fund's performance from calendar year to calendar year and by showing how the Fund's average annual total returns for one year, five years, and ten years compare with the Bloomberg U.S. Aggregate Bond Index. The Bloomberg US Treasury Bellwether 3 Month Index, Bloomberg US Treasury Bellwether 1 Year Index, ICE BofA 3-Month U.S. Treasury Bill Index and ICE BofA 1-Year U.S. Treasury Note Index show how the Fund's performance compares against the returns of indexes with similar investment objectives. The bar chart does not reflect any sales charges, which would reduce your return. The performance table reflects any applicable sales charges. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. More recent performance information is available at no cost by visiting TouchstoneInvestments.com or by calling 1.800.543.0407.
