Talen Energy Corporation (NASDAQ: TLN) announced today that its wholly owned subsidiary, Talen Energy Supply, LLC (“Talen” or the “Company”), received the requisite consents in its previously announced solicitation of consents (the “Consents”) from holders of its 8.625% Senior Secured Notes due 2030 (the “Notes”) with respect to the adoption of certain proposed amendments (the “Proposed Amendments”) to the Indenture, dated as of May 12, 2023 (as amended, supplemented or otherwise modified prior to the date hereof, the “Indenture”), among Talen, the guarantors party thereto and Wilmington Savings Fund Society, FSB, as trustee.

Talen sought the Proposed Amendments in order to (i) modify certain provisions, including certain covenants and related definitions, in the Indenture in order to substantially conform to the corresponding provisions set forth in the Company’s credit agreement dated May 17, 2023 (as amended, supplemented or otherwise modified prior to the date hereof) and (ii) waive Talen's right to optionally redeem up to 10.0% of the Notes prior to June 1, 2025 at a price equal to 103.000% of the aggregate principal amount of Notes to be redeemed.

The consent solicitation for the Notes (the “Consent Solicitation”) was made solely on the terms and subject to the conditions set forth in the consent solicitation statement dated January 6, 2025 (the “Consent Solicitation Statement”). The Consent Solicitation expired at 5:00 p.m. (New York City time) on January 13, 2025 (the “Expiration Time”). The Consents received in the Consent Solicitation were sufficient to effect the Proposed Amendments to the indenture governing the Notes.

Accordingly, the Company has entered into the fourth supplemental indenture to the Indenture (the “Fourth Supplemental Indenture”) to effect the Proposed Amendments. The Proposed Amendments will become operative upon the payment of the consent fee to the holders of the Notes who validly delivered Consents, which the Company expects to pay on January 14, 2025.
