(the "Fund"),

a series of Virtus Asset Trust

Supplement dated June 15, 2026 to the Fund's Summary Prospectus

and the Virtus Asset Trust Statutory Prospectus, each dated April 28, 2026, as supplemented

IMPORTANT NOTICE TO INVESTORS

As previously disclosed to shareholders, effective after the close of business on June 12, 2026, Virtus Fixed Income Advisers, LLC ("VFIA"), the subadviser to the Fund, has transferred the employees involved in the day-to-day management of the Fund from its Seix Investment Advisors ("Seix") division to its Newfleet Asset Management ("Newfleet") division. Accordingly, the Fund has been renamed Virtus Newfleet Intermediate Municipal Bond Fund, and all references to Virtus Seix Investment Grade Tax-Exempt Bond Fund are hereby changed to reflect the new name. Because Seix and Newfleet are both operating divisions of VFIA, this is not a change in subadviser and will not impact the management of the Fund.

Also effective after the close of business on June 12, 2026, the Fund's investment adviser has lowered the Fund's investment advisory fee rates so that they are contractually 0.45% on the first billion of the Fund's net assets and 0.40% on net assets over $1 billion. The resulting changes to the Fund's prospectuses are described in more detail below.
