Item 1.01. Entry into a Material Definitive Agreement.

On June 13, 2016, Voya Financial, Inc. (“Voya”) completed its registered public offering (the “Offering”) of $500 million aggregate principal amount of 3.650% Senior Notes due 2026 (the “2026 Notes”) and $300 million aggregate principal amount of 4.800% Senior Notes due 2046 (the “2046 Notes”). The 2026 Notes and the 2046 Notes are each guaranteed by Voya Holdings Inc., a wholly-owned subsidiary of Voya (“Voya Holdings”). The Offering resulted in aggregate net proceeds to Voya of approximately $791.5 million, after deducting commissions and estimated expenses. Voya intends to use such net proceeds to purchase certain outstanding notes and debentures of Voya and Voya Holdings and to pay fees and expenses related to such purchases.

Voya issued the notes under an indenture dated as of July 13, 2012 (the “Base Indenture”), as supplemented, in the case of the 2026 Notes, by a fifth supplemental indenture dated as of June 13, 2016 (the “2026 Supplemental Indenture”) and, in the case of the 2046 Notes, by a sixth supplemental indenture dated as of June 13, 2016 (the “2046 Supplemental Indenture,” and, together with the 2026 Supplemental Indenture, the “Supplemental Indentures,” and the Supplemental Indentures together with the Base Indenture, the “Indenture”), each among Voya, Voya Holdings and U.S. Bank National Association, as trustee (the “Trustee”).

Voya will pay interest on each of the 2026 Notes and 2046 Notes on June 15 and December 15 of each year, beginning on December 15, 2016. The 2026 Notes will mature on June 15, 2026 and bear interest at a rate of 3.650% per annum. The 2046 Notes will mature on June 15, 2046 and bear interest at a rate of 4.800% per annum. The terms of the Indenture, among other things, limits Voya’s ability to create liens, dispose of stock of certain subsidiaries and merge, consolidate or sell assets. Voya may, at its option, redeem, in whole or in part, the 2026 Notes or the 2046 Notes, at any time and from time to time. The provision of the Indenture governing the 2026 Notes and 2046 Notes each provide that certain events will constitute an event of default with respect to such notes.

The foregoing is only a summary of certain provisions and is qualified in its entirety by the terms of the Base Indenture, as filed with the Securities and Exchange Commission and incorporated by reference as an exhibit to Voya’s Registration Statement on Form S-3 (No. 333-196883), the 2026 Supplemental Indenture, a copy of which is filed herewith as Exhibit 4.1 and incorporated by reference herein, and the 2046 Supplemental Indenture, a copy of which is filed herewith as Exhibit 4.2, and incorporated by reference herein.

Please refer to the discussion under Item 1.01 above, which is incorporated under this Item 2.03 by reference.
