Introductory Note

On April 29, 2014, Energy Future Holdings Corp. and the substantial majority of its direct and indirect subsidiaries, including Energy Future Intermediate Holding Company LLC, Energy Future Competitive Holdings Company LLC and Texas Competitive Electric Holdings Company LLC (collectively, the “Debtors”), but excluding Oncor Electric Delivery Holdings Company LLC and its direct and indirect subsidiaries, filed voluntary petitions for relief (the “Bankruptcy Filing”) under Chapter 11 of the United States Bankruptcy Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”). During the pendency of the Bankruptcy Filing, the Debtors are operating their businesses as debtors-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code.

Item 7.01. Regulation FD Disclosure.

On April 14, 2015, the Debtors filed a Joint Plan of Reorganization pursuant to Chapter 11 of the Bankruptcy Code and a related Disclosure Statement with the Bankruptcy Court. On July 23, 2015, the Debtors filed a First Amended Joint Plan of Reorganization pursuant to Chapter 11 of the Bankruptcy Code and a related amended Disclosure Statement with the Bankruptcy Court. On August 3, 2015, the Debtors filed a Second Amended Joint Plan of Reorganization pursuant to Chapter 11 of the Bankruptcy Code (the “Amended Plan”). A copy of the Amended Plan is attached hereto as Exhibit 99.1.

The Bankruptcy Code does not permit solicitation of acceptances of the Amended Plan until the Bankruptcy Court approves the applicable Disclosure Statement relating to the Amended Plan. Accordingly, this Current Report on Form 8-K is not intended to be, nor should it be construed as, a solicitation for a vote on the Amended Plan. There can be no assurance that the Bankruptcy Court will approve a Disclosure Statement for the Amended Plan, that the Debtors’ stakeholders will approve the Amended Plan, or that the Bankruptcy Court will confirm the Amended Plan. The Debtors will emerge from Chapter 11 if and when the Amended Plan receives the requisite approval from holders of claims, an order confirming the Amended Plan is entered by the Bankruptcy Court, and certain conditions to the effectiveness of the Amended Plan, as stated therein, are satisfied.

The Amended Plan shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, is not otherwise subject to the liabilities of that section, and is not deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in such a filing.

Cautionary Note Regarding Forward-Looking Statements

This Current Report on Form 8-K includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, which are subject to risks and uncertainties. All statements, other than statements of historical facts, are forward-looking statements. Readers are cautioned not to place undue reliance on forward-looking statements. Although we believe that in making any such forward-looking statement our expectations are based on reasonable assumptions, any such forward-looking statement involves uncertainties and is qualified in its entirety by reference to the discussion of risk factors under “Risk Factors” and the discussion under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q filed by each of Energy Future Holdings Corp., Energy Future Intermediate Holding Company LLC and Energy Future Competitive Holdings Company LLC and the following important factors, among others, that could cause actual results to differ materially from those projected in such forward-looking statements:

2

Any forward-looking statement speaks only at the date on which it is made, and except as may be required by law, we undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which it is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for us to predict all of them; nor can we assess the impact of each such factor or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement. As such, you should not unduly rely on such forward-looking statements.
