Illinois Power Generating Company Filed for Court Approval of Prepackaged Reorganization Plan

HOUSTON --(BUSINESS WIRE)--Dec. 9, 2016-- Dynegy Inc. (NYSE: DYN) and Illinois Power Generating Company ( Genco ), an indirect, wholly owned subsidiary of Dynegy , announced today that they received the requisite accepting votes in favor of a prepackaged plan of reorganization (the Plan) for Genco . Genco subsequently filed a case under Chapter 11 of the United States Code (the Chapter 11 Case) in the United States Bankruptcy Court for the Southern District of Texas , Houston Division, to pursue confirmation of the Plan.

The filing followed the successful solicitation of acceptances for the Plan pursuant to an Offering Memorandum and Disclosure Statement, dated November 7, 2016 with respect to (1) an out-of-court exchange offer (the Exchange Offer) relating to Genco's outstanding 7.00% Senior Notes, Series H, due 2018, 6.30% Senior Notes, Series I, due 2020 and 7.95% Senior Notes, Series F, due 2032 (collectively, the Genco Notes) and (2) the concurrent solicitation of votes in favor of the Plan.

The Exchange Offer was terminated because the requisite participation threshold of 97% of the outstanding principal amount of Genco Notes was not satisfied, but Genco received votes approving the Plan from approximately 97% in amount and 83% in number out of the holders of Genco Notes who voted on the Plan.

RECEIVING DISTRIBUTIONS ON GENCO NOTES UNDER THE PLAN

The Plan distributions will be the same as those disclosed in our November 7, 2016 news release. Additional information will be provided to the holders of Genco Notes with respect to the procedures that will be required in order to receive Plan distributions. If such procedures are approved by the Court, any holder who fails to follow the required distribution procedures with respect to its Genco Notes on or prior to the 165th day after the effective date of the Plan will have its Noteholder Claim (as defined in the Offering Memorandum and Disclosure Statement) and its distribution pursuant to the Plan on account of such Noteholder Claim discharged and forfeited and will not receive any distribution under the Plan. Any property in respect of such forfeited Noteholder Claims will revert to Dynegy or Genco , as applicable.

OPERATIONS TO CONTINUE AS USUAL

Genco has asked the Court for authority for standard and customary "first day" relief to continue its operations in the ordinary course during the restructuring process. Illinois Power Marketing Company (including Homefield Energy) and Dynegy Energy Services are not a part of the filing. The men and women operating the Genco plants (Coffeen and Newton Power Stations) remain dedicated to upholding the highest standards of operational safety and environmental stewardship during the financial restructuring.
