**UPCOMING FUND CHANGE**

On May 20, 2026, the Board of Trustees of Voya Mutual Funds approved the following change to the Voya Multi-Manager International Small Cap Fund (the "Fund"), which is effective on June 22, 2026: the appointment of Lazard Asset Management LLC ("Lazard") as a sub-adviser to the Fund. Currently, Acadian Asset Management LLC ("Acadian") and Victory Capital Management Inc. ("Victory") each manage a portion of the Fund's assets. From June 22, 2026 through June 24, 2026, the Fund will be in a "transition period" during which time a portion of the Fund's assets currently managed by Acadian and Victory will be sold. During the transition period, the Fund may not be pursuing its investment objective and strategies with respect to this portion of the Fund's assets, and limitations on permissible investments and investment restrictions will not apply. The sale and purchase of securities during the transition period are expected to result in buy and sell transactions. Such transactions may be made at a disadvantageous time. These transactions will also result in costs, which will be borne by the Fund.
