**NOTICE OF IMPORTANT INFORMATION ABOUT** 

**UPCOMING FUND CHANGES**

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.

On November 13, 2025, the Board of Trustees of Voya Investors Trust (the "Board") approved a proposal to reorganize the Disappearing Portfolio with and into the following "Surviving Portfolio" (the "Reorganization"):

---

| | |
|:---|:---|
| **Disappearing Portfolio** | **Surviving Portfolio** |
| VY<sup>®</sup> CBRE Global Real Estate Portfolio | VY<sup>®</sup> CBRE Real Estate Portfolio (*to be renamed prior to the merger date as* VY<sup>®</sup> Columbia Real Estate Portfolio) |

---

The Reorganization is subject to approval by the shareholders of the Disappearing Portfolio. A proxy statement/prospectus detailing the proposed Reorganization is expected to be mailed to the Disappearing Portfolio's shareholders on or about May 6, 2026, and a shareholder meeting is scheduled to be held on or about July 9, 2026. The Disappearing Portfolio will notify its shareholders if shareholder approval of the proposed Reorganization is not obtained. If shareholder approval of the proposed Reorganization is obtained, it is expected that the proposed Reorganization will take place on or about July 24, 2026 (the "Closing Date").

If shareholders of the Disappearing Portfolio approve the proposed Reorganization, from the close of business on July 13, 2026 through the close of business on July 24, 2026, the Disappearing Portfolio will be in a "transition period" during which time the Disappearing Portfolio's holdings will, to the extent necessary, be aligned with those

X.288655-26 June 2026

of the Surviving Portfolio. During this time, the Disappearing Portfolio may not be pursuing its investment objective and strategies, and limitations on permissible investments and investment restrictions will not apply. The sales and purchases of securities during the transition period are expected to result in buy and sell transactions and such transactions may be made at a disadvantageous time.

In January 2026, Columbia Management Investment Advisers, LLC replaced CBRE Investment Management Listed Real Assets, LLC as the sub-adviser for the Surviving Portfolio and the Surviving Portfolio was renamed VY<sup>®</sup> Columbia Real Estate Portfolio. Additional information about VY<sup>®</sup> Columbia Real Estate Portfolio will be provided in the proxy statement/prospectus.

Please note that the Disappearing Portfolio and the Surviving Portfolio are not offered directly to the public. Purchase and sale of shares of the Disappearing Portfolio may be made only by separate accounts of insurance companies serving as investment options under Variable Contracts or by Qualified Plans, custodian accounts, and certain investment advisers and their affiliates, other investment companies, or permitted investors.

Following the Reorganization, the Disappearing Portfolio's shareholders will hold shares of the Surviving Portfolio.
