**NOTICE OF IMPORTANT INFORMATION**

**ABOUT PROPOSED FUND REORGANIZATIONS**

On May 15, 2025, the Board of Directors of Voya Partners, Inc. (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> T. Rowe Price Growth Equity Portfolio | Voya Large Cap Growth Portfolio (a series of Voya Investors Trust) |

---

The proposed 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 August 29, 2025, and a shareholder meeting is scheduled to be held on or about October 14, 2025. 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 at the close of business on or about November 21, 2025 (the "Closing Date").

If shareholders of the Disappearing Portfolio approve the proposed Reorganization, from the open of business on October 15, 2025 through the close of business on November 21, 2025, the Disappearing Portfolio will be in a "transition period" during which time the Disappearing Portfolio's holdings will be aligned with those 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.

X.75962-25A July 2025

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

The proposed 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 Portfolios' shareholders on or about October 1, 2025, and shareholder meetings are scheduled to be held on or about November 20, 2025. The Disappearing Portfolio will notify their shareholders if shareholder approval of a 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 December 5, 2025 (the "Closing Date").

If shareholders of the Disappearing Portfolio approve the proposed Reorganization, from the open of business on November 21, 2025 through the close of business on December 5, 2025, the Disappearing Portfolio will be in a "transition period" during which time a transition manager will, to the extent necessary, align the Disappearing Portfolio's holdings with those of the Surviving Fund. During this time, the Disappearing Portfolio may not be pursuing their 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.

Please note that the Disappearing Portfolio is 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. The Surviving Fund is offered directly to the public and eligibility to invest in the Surviving Fund is not restricted in the same manner as the Disappearing Portfolio. As a result, the Surviving Fund may not be appropriate for certain shareholders investing under Variable Contracts. Additional information will be provided in the forthcoming proxy statement/prospectus.

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