Introduction

Energy Future Holdings Corp. (“EFH Corp.”), Energy Future Competitive Holdings Company LLC (“EFCH”), Texas Competitive Electric Holdings Company LLC (“TCEH”), and Energy Future Intermediate Holding Company LLC (“EFIH” and together with EFH Corp., EFCH and TCEH, the “Companies”) executed confidentiality agreements (the “Confidentiality Agreements”) in September and October 2013 with certain unaffiliated holders of first lien senior secured claims against EFCH, TCEH and certain of TCEH’s subsidiaries (collectively, the “TCEH Creditors”), certain unaffiliated holders of unsecured claims against EFIH (collectively, the “EFIH Unsecured Creditors”), a significant unaffiliated holder of claims against TCEH, EFCH, EFIH and EFH Corp. (the “Significant Creditor”) and an unaffiliated holder of first lien claims against EFIH (the “EFIH First Lien Creditor” and, collectively with the TCEH Creditors, the EFIH Unsecured Creditors and the Significant Creditor, the “Creditors”), to facilitate discussions with the Creditors concerning the Companies’ potential restructuring (the “Restructuring”). Pursuant to certain of the Confidentiality Agreements, on October 15, 2013, the Companies publicly disclosed that they and certain of the Creditors had engaged in discussions concerning the Companies’ capital structure, as well as certain confidential information concerning the Companies that the Companies had provided to those Creditors.

Since October 15, 2013, from time to time, certain of the Creditors have continued to engage in negotiations with the Companies with respect to the Restructuring. Pursuant to the Confidentiality Agreements, the Companies agreed to disclose publicly after a specified period if certain conditions were met that the Companies and the Creditors have engaged in discussions concerning the Companies’ capital structure, information regarding such discussions and certain confidential information concerning the Companies that the Companies have provided to the Creditors. The information included in this Current Report on Form 8-K is being furnished to satisfy the Companies’ public disclosure obligations under the Confidentiality Agreements.

Discussions with Creditors

Following execution of certain of the Confidentiality Agreements and as previously disclosed, in September 2013, the Companies, principals of EFH Corp.’s existing equity holders (the “Equity Holders”) and certain of the Creditors engaged in discussions with respect to the Companies’ capital structure, including the possibility of a consensual, pre-packaged restructuring transaction. Following the disclosure on October 15, 2013, the Companies and the Equity Holders continued to engage in discussions with various Creditors from time to time.

During these continued discussions, the Companies shared with the Creditors prospective financial information. In addition, during discussions regarding the Restructuring, the Companies created a proposal as set forth in Exhibit 99.1 (the “Companies’ Proposal”) to, among other things, facilitate dialogue and consensus among the parties, the EFIH Unsecured Creditors made a proposal as set forth in Exhibit 99.2 (the “EFIH Unsecured Creditor Proposal”), the Significant Creditor made an oral proposal to the Companies and certain of the Creditors, the material terms and conditions of which are described in Exhibit 99.3 (the “Significant Creditor Proposal”), and the TCEH Creditors made a proposal as set forth in Exhibit 99.4 (the “TCEH Creditor Proposal” and collectively with the Companies’ Proposal, the EFIH Unsecured Creditor Proposal and the Significant Creditor Proposal, the “Proposals”).

In discussions among certain Creditors and the Equity Holders, the Equity Holders proposed that they would retain 4% of EFH Corp.’s common equity interests under the Companies’ Proposal after implementation of the Restructuring, with first lien senior secured creditors of TCEH receiving, among other things, the remaining 96% of EFH Corp.’s common equity interests (in both cases subject to dilution in the manner described in the Companies’ Proposal).

In addition, the Companies had various discussions with the EFIH First Lien Creditor and its advisors with respect to refinancing the first lien claims against EFIH. However, these discussions did not result in a consensus on the terms of such refinancing that was within the range of the refinancing terms for such claims contained in any of the Proposals.

2

The Companies’ objectives in these discussions were to promote a sustainable capital structure and maximize enterprise value by, among other things, encouraging agreement on a restructuring plan that would minimize time spent in a restructuring through a proactive and organized solution; minimizing any potential adverse tax impacts of a restructuring; maintaining the Companies in one consolidated group; maintaining focus on operating EFH Corp.’s businesses; and maintaining the Companies’ high-performing work force. The Companies, the Equity Holders and the Creditors have not reached agreement on the terms of any change in the Companies’ capital structure.

To effect a Restructuring, the Companies’ Proposal and the TCEH Creditor Proposal contemplated that some combination of EFH Corp. and certain of its subsidiaries (including EFIH, EFCH and TCEH but excluding Oncor Electric Delivery Holdings Company LLC (“Oncor Holdings”) and Oncor Electric Delivery Company LLC (“Oncor”)) would implement a plan of reorganization by commencing one or more voluntary cases under Chapter 11 of the United States Bankruptcy Code (“Code”), and the EFIH Unsecured Creditor Proposal contemplated that EFIH (excluding Oncor Holdings and Oncor) would implement a plan of reorganization by commencing a stand-alone voluntary case under the Code. The Companies’ Proposal and the TCEH Creditor Proposal would have resulted in a pre-negotiated restructuring of EFCH’s approximately $32.2 billion principal amount of debt, EFH Corp.’s approximately $650 million principal amount of debt and EFIH’s approximately $7.6 billion principal amount of debt (each as of September 30, 2013 and excluding debt held by affiliates). The confirmation of any plans of reorganization in such cases would be subject to applicable regulatory approvals. The Companies’ Proposal and the TCEH Creditor Proposal further contemplated that after the Restructuring EFH Corp. would continue to hold all of the equity interests in EFCH and EFIH; EFCH would continue to hold all of the equity interests in TCEH; and EFIH would continue to hold all of the equity interests in Oncor Holdings. The EFIH Unsecured Creditor Proposal contemplated that after the Restructuring certain creditors of EFIH would own a substantial majority of, and certain creditors of EFH Corp. and the Equity Holders would collectively own a minority of, the equity interests in EFIH.

The Companies also disclosed to the TCEH Creditors that they have negotiated for commitments from certain third-party financial institutions to provide, in the event EFCH, TCEH and certain of TCEH’s subsidiaries were to file for protection under the Code, up to $3.6 billion of senior secured debtor-in-possession loans, with an additional uncommitted facility of up to $750 million (such loans, the “Proposed TCEH DIP Loan”). The Proposed TCEH DIP Loan would, among other things, (i) be secured by a priming first priority lien on and security interest in substantially all of the assets of EFCH, TCEH and certain of TCEH’s subsidiaries (subject to certain exceptions), (ii) mature within twenty-four months (subject to extension by six months if certain conditions were satisfied) and (iii) include other terms and conditions customary for debtor-in-possession loans.

The Companies are not currently engaged in ongoing negotiations with the principals of any of the Creditors. Although the Creditors are not currently engaged in ongoing negotiations with the Companies, certain of the Creditors have directed their advisors to continue to work with the Companies and their advisors to explore further whether the parties can reach an agreement on the terms of a consensual restructuring.

The Companies expect to continue to explore all available restructuring alternatives to facilitate the creation of a sustainable capital structure for the Companies. In addition, the Companies and the Equity Holders may engage from time to time in additional discussions with the Creditors, other creditors of the Companies, and professional advisors to such creditors. Such discussions may include proposed changes to the Companies’ capital structure. There can be no guarantee that any future changes in the Companies’ capital structure will occur or, if any changes occur, that they will occur as described above or as set forth in any of the Proposals, ultimately be successful, or produce the desired outcome.

The TCEH Creditors that signed confidentiality agreements with the Companies and that supported the TCEH Creditor Proposal hold, in the aggregate, less than 66.7% of the total outstanding amount of the TCEH first lien debt. The EFIH Unsecured Creditors that signed confidentiality agreements with the Companies and that supported the EFIH Unsecured Creditor Proposal hold, in the aggregate, less than 66.7% of the total outstanding amount of EFIH unsecured debt.

Financial Information

3

EFH Corp. and its subsidiaries generally do not publicly disclose detailed prospective financial information. However, in connection with their discussions with the Creditors and their respective advisors, the Companies provided certain financial information, consisting largely of forecasts, to the Creditors and their respective advisors. Management of the Companies prepared the forecasts from certain internal financial projections based on reasonable expectations, beliefs, opinions, and assumptions of the Companies’ management at the time they were made. The forecasts were not prepared with a view towards public disclosure and were not prepared in accordance with generally accepted accounting principles (“GAAP”) or published guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of “prospective financial information.”

The inclusion of the forecasts in this Current Report on Form 8-K should not be regarded as an indication that the Companies or any other person considered, or now consider, this information to be necessarily predictive of actual future results, and does not constitute an admission or representation by any person that such information is material, or that the expectations, beliefs, opinions, and assumptions that underlie such forecasts remain the same as of the date of this Current Report on Form 8-K, and readers are cautioned not to place undue reliance on the prospective financial information.

Neither the independent auditor of the Companies nor any other independent accountant has examined, compiled, or performed any procedures with respect to the prospective financial information contained herein and, accordingly, none has expressed any opinion or any other form of assurance on such information or its achievability and none assumes any responsibility for the prospective financial information.

The prospective financial information:

All of the financial information contained in this section entitled “Financial Information” is forward-looking in nature. The information is subjective in many respects and thus subject to interpretation. Further, the information relates to multiple future years and such information by its nature becomes less predictive with each succeeding year. The Companies cannot provide assurance that the financial projections will be realized; rather, actual future financial results may vary materially from the forward-looking information presented herein.

Except as required by law, none of EFH Corp., EFCH or EFIH currently intends to update or revise publicly any of the information presented herein to reflect circumstances or other events occurring after the date the financial projections were prepared or to reflect the occurrence of future events. These considerations should be taken into account in reviewing the financial projections, which were prepared as of an earlier date. For additional information on factors that may cause actual future financial results to vary materially from the information presented herein, see the section entitled “Cautionary Note Regarding Forward-Looking Statements” below.

The Companies provided the Creditors and their respective advisors with the projected financial forecasts for EFH Corp. and EFIH below, assuming (i) as of June 30, 2014, payment of $1.150 billion of cash using funds distributed by TCEH in full satisfaction of $2.2 billion (including accrued interest) of EFH Corp. and EFIH unsecured debt, (ii) the redemption of $1 billion of EFIH second lien notes at emergence using funds distributed by TCEH to EFH Corp., and subsequently contributed by EFH Corp. to EFIH, (iii) a refinancing of the EFIH first lien notes and the EFIH second lien notes (other than the $1 billion of EFIH second lien notes to be redeemed at emergence) at certain market rates, and (iv) financing fees equal to 1.5%. The amounts may not foot due to rounding.

The information provided by the Companies to the Creditors and their advisors also included forecasts for debt and leverage ratios for EFH Corp. and EFIH based on the assumptions described above the immediately preceding table.

At September 30, 2013, EFH Corp. had $225 million of cash and cash equivalents, EFIH had $329 million of cash and cash equivalents and TCEH had $1.262 billion of cash and cash equivalents and $171 million of available capacity under its letter of credit facility.

Readers are cautioned not to place undue reliance on forward-looking statements.
